July 20, 2007 Mr. Andrew Dillenburg Lehman Brothers Real Estate Private Equity 399 Park Avenue, 11th Floor New York, New York 10022 RE: Heritage Fields Master-plan (2,107± Gross Acres)

Irvine, California 92618 C&W File ID. 07-31028-9175 Dear Mr. Dillenburg: Pursuant to your request, we performed a real property appraisal of the Heritage Fields master-plan project (formerly Marine Corp Air Station El Toro) in El Toro, California as more particularly described in the self-contained narrative appraisal report to follow. The appraisal was prepared to estimate the market value “as is” of the subject property. The intended use of this report is for the client, Lehman Brothers, for loan underwriting. It may be used in connection with the acquisition, disposition, and financing of the sale of the property. As currently proposed, Heritage Fields will consist primarily of residential, parks/recreation, and R&D land uses. Land uses and allocated acreages vary by district. The total land area for that area of the project which is the subject of this appraisal is approximately 2,107 gross acres or 2,086 acres net. The majority of the land within the Heritage Fields project is dedicated for residential development. Based on current entitlements, upon buildout the project could include up to 3,625 residential units. In the Lifelong Learning District, 1,026 homes are planned on 116 residential acres with construction types including but not limited to: faculty housing, mid-rise flats, single-family detached, and luxury triplexes. Other significant land use distributions in the Lifelong Learning District are 223 education acres, 215 exposition acres, 163.2 agricultural acres, 77.8 R&D acres, and 73.2 cemetery acres. For the Park District, 1,100 homes are planned on 365 residential acres with a wide range of single-family detached housing types. Other substantial land uses in the Park District are 306 golf course acres and 85 park/recreation acres. The Transit-Oriented District has approximately 1,500 housing units planned for 134.7 residential acres with townhome, apartment, and single-family detached construction types. The other primary land use in the Transit-Oriented District is 113 R&D acres.

We, Brian J. Curry, MAI, SRA, and Edward A. Carlson, MAI, made a careful inspection of the property, gathered and analyzed considerable data and information having a bearing on its values. Our findings are submitted in this report. Based on our investigation and analyses, it was our opinion that as of July 1, 2007, the market value “as is” as defined herein, representing the fee simple interest in this property and subject to the assumptions as set forth within the body of this report, was as follows:

$1,060,000,000 One Billion Sixty Million Dollars

Date of Value – July 1, 2007 The appraisers recognize the assistance of Richard Zbranek, MAI, Tim Garey, Michele Kauffman, Chris Kelsey, Lori Matzke, and Tracie Tyler, all appraisers with Cushman & Wakefield, in various analyses, valuation, and final report preparation. As the subject is a master-planned community, the valuation methodology incorporated land use and cost assumptions. Of significant importance is that the appraisers relied upon the proposed land use and development cost budgets provided by the master developer. It was assumed that the submitted project costs and reimbursements were accurate for use in this analysis. Please reference the Extraordinary and General Limiting Conditions section of this report regarding additional assumptions relevant to the analyses and valuation conclusions contained herein. This report contains a total of 344 pages plus separately bound Addenda, which is a required portion of this report. The appraisal was prepared in conformance with the Uniform Standards of Professional Appraisal Practice (USPAP) adopted by the Appraisal Foundation, the regulations adopted by the Office of the Comptroller of the Currency; the Code of Professional Ethics and Standards of Professional Conduct of the Appraisal Institute; and Lehman Brothers Appraisal Guidelines. This appraisal report was prepared for use by Lehman Brothers. The appraisers and Lehman Brothers make no express or implied representation or warranty of any kind, and expressly disclaim any liability to any other person or entity with respect to the appraisal report. Again, the reader of this report is advised to give special attention to the Extraordinary and General Limiting Conditions upon which the valuation analyses and conclusions were drawn.

EXTRAORDINARY ASSUMPTIONS 1. The appraisers relied on land development cost and reimbursements estimates provided by the

developer. It was assumed that the costs were reasonably true and correct. Any substantial changes in the cost estimates could have an effect on the value conclusions and the feasibility of development. It was assumed that competent and professional engineering has been completed and that the cost estimates were prepared by a qualified, professional service. A copy of the developer’s pro forma with estimated costs is included the Addenda.

2. The developer provided the appraisers with a land development pro forma. The pro forma presented

land sale revenues, critical path, etc. that may have been relied upon for this appraisal. It was assumed that information in the pro forma, and subsequent “verbal” updates by the developer, was true and correct. Note that any substantial changes in the estimates would have an effect on market value conclusions. A copy of the developer’s pro forma is included the Addenda.

3. It was assumed that the subject site is of a physical and legal nature that would allow for the

development of all residential and non-residential property types as presented in the developer’s latest business plan.

4. The developer intends to finance major backbone and/or other improvements via a public financing

vehicle through a Community Facility Districts (CFDs). Per the developer, it was assumed that the overall tax rate, including base and special assessments, for market rate units will be 1.75% and for active-adult housing will be 1.55%. For non-residential commercial property the burden is estimated at $4.00 per square foot. It was assumed the agricultural parcels will not be subject to special assessments. Any changes in the proposed tax burden structure would likely affect the appraisal analyses and conclusions.

5. It was assumed that land development of the subject property will proceed as currently proposed with

no substantial delays due to legal consequences, lack of adequate infrastructure, utilities, etc. 6. This appraisal report was prepared for use by Lehman Brothers. The appraisers and Lehman Brothers

make no express or implied representation or warranty of any kind, and expressly disclaim any liability to any other person or entity with respect to the appraisal report.

7. The property, being a former US Navy facility, includes several so-called LIFOC (Lease In

Furtherance of Conveyance) parcels which will be conveyed to the developer subsequent to final environmental clearance hurdles. This protocol is standard in base realignment and disposition scenarios such as the Heritage Fields project. It was assumed that environmental clearance and conveyance will proceed with no substantial obstacles that would alter the development plan as currently proposed by the master developer.

8. Acceptance of, and/or use of this report constitutes acceptance of the above extraordinary

assumptions.

GENERAL ASSUMPTIONS AND LIMITING CONDITIONS 1. The property benefits from an approved vesting tentative tract map. This is typical of master-planned

communities in the area and not anticipated to unduly hinder the subject’s development as proposed. It is recommended that the client have available a copy of the Tentative Map(s) Conditions of Approval and retain appropriate legal council to review said document to assess the impact of the Conditions in their lending decisions.

2. The developer provided a preliminary title report (Order No. 7002439-23) prepared by First

American Title Company, dated December 7, 2006. The report is included in the addenda. There were numerous listed exceptions, primarily utility easements. No significant adverse easements, conditions, or encroachments, which were deemed to have a substantial impact on value, were noted upon review of the report or during the onsite inspection. The property was appraised assuming clear title and no unknown adverse easements or encroachments. A full title review is recommended.

3. The property rights appraised were the fee simple interest. It is recognized there are several short-term

leases for older properties on the property. We have not specifically analyzed said leases. 4. The appraisers relied on various information provided by the County of Orange, Lennar, the Concord

Group, Hanley Wood, REIS, and others. All of said information was assumed reasonably true and correct.

5. The appraisers included adjustment grids in the analyses. Specific adjustments were not deemed to be

absolute but were the appraisers’ attempt to reflect value contributions of the various factors in the marketplace. The adjustment process is sometimes fairly subjective in nature, primarily due to the many characteristics of value, variances in buyer/seller influences, imperfections in the market, etc. The adjustment grids represent an empirical format to simply lead the reader to a logical conclusion of the appraisers’ estimates.

6. Individual residential planning area values incorporated hypothetical product line assumptions, which

is typical of master-planned communities. No guarantee can be made as to eventual specific product constructed in each respective neighborhood. However, it was assumed that the planning areas/parcels would be developed with product relatively similar to that of the assumed hypothetical product.

7. The appraisers were provided copies of Soils, Hazardous Waste, Geotechnical, Environmental site

assessment reports prepared by various individuals and/or professional services. Per the studies, there were no soils, hazardous waste, geotechnical, or environmental conditions that would preclude development as proposed. It was assumed that all mitigation measures can be accomplished per the provisions found in the Environmental Impact Report. Further, it was assumed that any and all costs of potential mitigation measures, the responsibility of the master developer (buyer), have been discovered and included in the developer’s cost budget. For further details, it is recommended that the reader refer to a copy of the Environmental Impact Report.

8. All exhibits included in this report, including all maps, are for illustrative purposes only. The

appraisers make no guaranty as to the absolute accuracy of the boundaries depicted on any map, or the exact location of any properties illustrated on any exhibit.

9. No responsibility was assumed for the legal description or title considerations. Title to the property was assumed to be good and marketable unless otherwise stated.

10. The property was appraised free and clear of any or all liens or encumbrances unless otherwise stated. 11. Responsible ownership and competent property management were assumed. 12. The information furnished by the client and others was believed to be reliable. However, no warranty

is given for its accuracy. 13. All engineering was assumed to be correct. The sketches and maps in this report were included to

GENERAL INFORMATION PROPERTY IDENTIFICATION / LEGAL DESCRIPTION The subject property encompasses the proposed Heritage Fields master-plan in El Toro, California. Heritage Fields represents the redevelopment of the former Marine Corps Air Station El Toro and generally located north of Interstate 5, south of Portola Parkway and Irvine Boulevard, west of Alton Parkway and east of Highway 133. A full legal description of the property may be found in the preliminary title report in the Addenda.

STATEMENT OF OWNERSHIP According to the developer, as of the date of value, title to the estate, or interest, was vested in the name of Heritage Fields, LLC. Title was held in fee. DATE OF APPRAISAL / DATE OF REPORT The date of market value “as is” was July 1, 2007. The date of appraisal report was July 20, 2007.

INTENDED USE / INTENDED USER The appraisal was prepared to estimate the market value “as is” of the subject property. The intended use of this report is for the client, Lehman Brothers, for loan underwriting. It may be used in connection with the acquisition, disposition, and financing of the sale of the property. This appraisal report was prepared for use by Lehman Brothers. The appraisers and Lehman Brothers make no express or implied representation or warranty of any kind, and expressly disclaim any liability to any other person or entity with respect to the appraisal report. SCOPE OF THE APPRAISAL The client requested a comprehensive narrative appraisal reported in a self-contained narrative report. The appraisal was prepared in conformance with the Uniform Standards of Professional Appraisal Practice (USPAP) adopted by the Appraisal Foundation; the regulations adopted by the Office of the Comptroller of the Currency; the Code of Professional Ethics and Standards of Professional Conduct of the Appraisal Institute; and Lehman Brothers Appraisal Guidelines. The appraisal assignment was not based on a requested minimum valuation, a specific valuation, or the approval of a loan. The property was last inspected in June 2006. The developer, Lennar, provided pertinent information regarding the project, including title report, proposed land use plan, lot/planning area exhibits, Environmental Impact Report, Design Guidelines, Tentative Map, business plan, revenue/costs pro forma, and other general information regarding the subject. Regional, city, and neighborhood data were based on numerous public and private sources, published studies, reports, and articles. The regional, city, and neighborhood descriptions were also based on a physical inspection by the appraisers. Site and improvement

data were based on physical inspection of the subject, as well as plans, studies, assessor's records, budgets/schedules, and exhibits provided to the appraisers. In estimating the highest and best use for the property, an analysis was made of the data compiled in the above noted steps. Furthermore, a study and analysis of the residential and commercial markets in the subject area (Market Analysis) was performed to determine the financial feasibility and maximally profitable use of the proposed community. In developing the appropriate approaches to value, market data were collected from Comps Incorporated, Hanley Wood, The Concord Group, Orange County deed records, in-house materials, and other sources. The appraisers confirmed all sales, market, and/or other data used in the report with one or more persons and focused the data search on the subject's sphere of influence. Persons contacted included buyers, sellers, brokers, property developers, public officials, and others. The data collected and confirmed has been reported to an extent sufficient for the particular appraisal problem involved. After assembling and analyzing the data defined in the scope of the appraisal, a final estimate of market value was made. In the valuation process, three approaches to value are typically used. The cost approach requires an analysis of sales of similar parcels into an estimate of market value for the subject site. An estimate is then made as to the cost to replace the subject’s improvements at today’s costs using reliable sources of cost data. Depreciation or obsolescence from all causes is estimated based on the experiences of similar properties. This is then deducted from the replacement cost if new to arrive at the present worth of the improvements and the site. In analyzing the property, the appraisers performed static and yield residual analyses of the subdivision development method for residential product. This methodology is essentially an inverse cost approach analysis used by investors/builders analyzing a probable purchase price for the subject after deducting the appropriate costs for all other agents of production. Therefore, a cost approach analysis was inherently performed by the appraisers in the valuation of the subject. In the income approach, the property’s ability to generate net operating income is fully analyzed. The basis of this approach is founded on the principle of discounting the anticipated flow of future benefits into a present value indication. A variation of the income approach and cost approach, the development method, was used to estimate the market values of the various residential planning areas/parcels. This method provided estimates of the market value as finished superpads by estimating aggregate retail sales proceeds from proposed improvements and deducting profit and expenses in an appropriate manner. The development method accounts for the cost to develop the homes and all expenses, including a profit factor for the risk involved. A static residual model and yield analysis discounted cash flow (DCF) were used for this procedure. For the yield analysis, the periodic net revenues are discounted to determine the present worth of the future income stream after deducting development costs, costs to complete, and expenses. The sum of the discounted net incomes results in the estimated market value of the planning area (land). The static model incorporated the features of the yield model, but was presented in a cumulative line format. After the market values “at completion” of the residential planning areas/parcels were estimated, these figures were inputted into a larger master discounted cash flows to estimate the “as is” market value for the entire property.

For land, the sales comparison approach is typically deemed the most appropriate. The sales comparison approach involves the comparison of sales, listings, expired listings, offers, etc. of properties to the subject (comparables) to indicate and provide a basis for determining its value. Adjustments and/or comparisons of the comparables are made to the subject relative to differences or similarities in property rights conveyed, financing, sale conditions, market conditions, location, legal, and physical characteristics. The basis for the adjustments and/or comparisons is generally formulated from data which indicate reactions of buyers and sellers to these differences. A range of adjusted values for the subject is usually found in this approach. The appraisers must correlate the range into a final indicated value by selectively rating the comparables as to their overall comparative values. The sales comparison approach was used in estimating the market value of the individual subject planning areas/parcels for both residential and commercial use. Also, a sales comparison analysis was considered in valuing the entire property. Said analysis would involve comparing larger master-planned community land sales to the subject property, adjusting for the various differences discussed above. In that there were few recent master-planned community sales from the larger Orange County area, and each master-planned community varies substantially in physical and financial characteristics (i.e. development potential), this approach had very limited application in this analysis. Additionally, due to the large project size of master-planned communities, most developers/buyers of master-plans analyze the individual component neighborhoods within the master-plans in arriving at a reasonable price for the entire property. Accordingly, the sales comparison approach to the entire master-plan was not deemed appropriate. HISTORY OVERVIEW OF SUBJECT PROPERTY The subject property represents a portion of what was the Marine Corp Air Station El Toro (MCAS El Toro). The decision to close MCAS El Toro was made by the Department of Navy (DON) under the Base Realignment and Closure Act in July, 1993. Since that time several plans for the reuse of the site have been prepared by various entities including the County of Orange, El Toro Reuse Planning Authority (ETRPA), and the City of Irvine. The current plan, called the Orange County Great Park Plan, is consistent with the concept for reuse of El Toro approved by the voters of Orange County in the March, 2002 initiative (Measure W). The Measure W initiative resulted in the designation of MCAS El Toro for park, open space and other uses and incorporating the site into the City of Irvine. On April 23, 2002, shortly after the passage of Measure W, the DON announced its intention to sell the property by public auction in accordance with federal surplus property disposal procedures. Following the DON decision to sell the land at public auction, the City of Irvine developed a concept plan to assure that the orderly development of the “great park” consistent with the Measure W initiative could be realized through the private sector. The objective of the Orange County Great Park Plan was to allow a reasonable economic return to the private sector buyer while assuring park, open space and other public areas would be dedicated to the City or other non-profit or governmental entity in perpetuity and improved without cost to the local taxpayer.

The City prepared a land plan that would allow for increased development intensities in exchange for the private sector participation in a development agreement that required the full dedication and improvement of public infrastructure and open space amenities. The City’s strategy was to allow for intensified private development under a Development Agreement arrangement in return for dedication of lands to be used for park, open space and public and institutional purposes. The City also created a less intense development plan as the base/underlying zoning designation which would allow for the future private sector owner to decide for itself as to whether or not to pursue the more development intense overlay zoning through a development agreement. On July 8, 2003, the Irvine City Council adopted Ordinance No. 03-19, approving the original version of the development agreement and on July 1, 2004 the Planning Commission of the City held a public hearing, after certain findings and determinations had been made in regards to the development, recommending the City Council that the earlier agreement be approved. On October 12, the City Council also held a public hearing and adopted Ordinance No. 04-13, approving the earlier version of this agreement. Upon completion of the bidding process and the purchase of the property, in 2005 the city sought to revise the 2004 version of the Development Agreement and on May, 5, 2005 the Planning Commission held a public hearing for the new agreement and recommended its approval. On May 10, 2005, the City Council also held a public hearing for the new agreement and on May 24, 2005 adopted Ordinance No. 05-10 approving the new agreement.

The purchase of the former Marine Corps Air Station at El Toro took place in early 2005. By way of winning bid via online auction, Heritage Fields, LLC acquired the property for a total purchase price of $649,500,000. The land was subsequently transferred on July 12, 2005 from federal control to Heritage Fields, which voluntarily entered into a Development Agreement with the City of Irvine that guaranteed limited development rights in return for a package of land dedication and fees to be used by the City to develop the Orange County Great Park. The market value “as is” has been reconciled at $1,060,000,000, which is substantially higher than the most recent 2005 acquisition price of $649,500,000. A review of the builder’s cost budget indicated approximately $270,000,000 have been expended on the project to-date. Thus, total costs to date, including the land basis, were nearly $920,000,000. This figure does not include an additional $74,000,000 paid to SunCal Communities as a “redemption fee” to dissolve a partnership and various indirects costs such as property taxes, management, etc. Thus, total expenditures to date are over $1,000,000,000, quite similar to the “as is” appraised value. The property has benefited from extensive cost expenditures and advancement in entitlements since acquisition. On the other hand, market conditions have softened since the purchase date in 2005. The appraised value was deemed reasonable given the foregoing discussion

EXPOSURE AND MARKETING TIME The estimated market value of the subject was premised on achieving a sale of the project in a reasonable exposure and marketing time. Indications of the exposure time associated with the market value estimate were provided by exposure times of master-planned community land sales in Los Angeles, Orange, Riverside, and San Diego Counties, interviews with participants in the market, and an analysis of general economic conditions. Exposure times were quoted as typically ranging from three to twelve months depending on the complexity of the property, size of investment, etc. Given that the subject is located in an active for-sale housing submarket with strong potential for future housing demand, it would likely generate substantial interest on part of potential buyers if offered for purchase. However, the large scale of the project, and the significant investment capacity to execute an acquisition of this type, limits the number of qualified buyers. A marketing and/or exposure period of six to twelve months was deemed reasonable for the larger property “as is.” An acquisition such as the subject property would require a large equity investment. The most probable buyer profile for a project such as the subject would include larger regional and national developers and/or builders, which often joint venture with various equity partners. PERSONAL PROPERTY, FIXTURES, AND INTANGIBLE ITEMS The property valued in this assignment did not include any personal property, fixtures, equipment, or intangibles. The contributory value of any such items was not applicable for this assignment and was not reflected in the reported value conclusions. Notable is that the model homes in the planned development would likely include various personalities and furnishings, which were not included in the appraised values. DEFINITION OF FEE SIMPLE ESTATE The property rights of ownership appraised were the fee simple estate. The fee simple title is regarded as an estate without limitations or restrictions and can be defined as:

Absolute ownership unencumbered by any other interest or estate, subject only to the limitations imposed by the governmental powers of taxation, eminent domain, police power, and escheat.1

DEFINITION OF MARKET VALUE For this assignment, market value can be defined as:

The most probable price which a property should bring in a competitive and open market under all conditions requisite to a fair sale, the buyer and seller, each acting prudently and knowledgeably, and assuming the price is not affected by undue stimulus. Implicit in this definition is the consummation of a sale as of a specified date and the passing of title from seller to buyer under conditions whereby: (1) buyer and seller are typically motivated; (2) both parties are well informed or well advised, and acting in what they consider their own best

interest; (3) a reasonable time is allowed for exposure in the open market;

(4) payment is made in terms of cash in U. S. dollars or in terms of financial arrangements

comparable thereto; and (5) the price represents the normal consideration for the property sold unaffected by special or

creative financing or sales concessions granted by anyone associated with the sale.2 DEFINITION OF MARKET VALUE “AS IS” The scope of this assignment included providing a market value “as is” estimate for the entire property. Market value “as is” can be defined as:

The value of specific ownership rights to an identified parcel of real estate as of the effective date of the appraisal; relates to what physically exists and is legally permissible and excludes all assumptions concerning hypothetical market conditions or possible rezoning.3

DEFINITION OF MARKET VALUE “AT COMPLETION” The scope of this assignment included providing market value “at completion” estimates for the individual planning areas as graded superpads. Prospective market value “at completion” can be defined as:

Market value as if complete on appraisal date means the market value of a property with all proposed construction, conversion, or rehabilitation hypothetically completed, or under other specified hypothetical conditions as of the date of the appraisal.4

DEFINITION OF FINISHED LOTS For this assignment, finished lots can be defined as:

A parcel which as legal development entitlements created by a recorded subdivision map and a physical condition which includes fine graded, level building pads with an intract infrastructure abutting the individual lots consisting of asphalt paved right-of-way with concrete curb, gutter, sidewalks and street lighting in addition to necessary wet and dry utilities. With the exception of building permit and plan check fees, the finished lot condition also assumes prepayment of all applicable development fees including school and development impact fees.5

DEFINITION OF BLUE TOP LOTS For this assignment, blue top lots can be defined as:

A parcel which has legal development entitlements created by a recorded subdivision map and a physical condition which includes graded, level “certified” building pads and streets with offsite infrastructure abutting the neighborhood perimeter. A blue top condition would not include street improvements and completed intracts but would include installed utilities in the rights-of-way and stubbed to individual lots.6

DEFINITION OF AGGREGATE RETAIL REVENUES For this assignment, aggregate retail revenues can be defined as:

The sum of a number of individual market values of discrete units of realty: e.g., finished sites, condominiums, detached single family residences, individual units in a planned unit development, etc. Aggregate retail revenues is not a market value. The basic assumption underlying this value is that each unit will be sold individually at full market (retail) price (i.e., market value) to as many buyers as there are units on the same (effective) date of value. In the market valuation process each unit is individually valued based on market evidence. Then, those individual market values are totaled to arrive at the aggregate retail revenues.8

REGIONAL DESCRIPTION “Orange County”

MARKET OUTLOOK The outlook for the Santa Ana-Anaheim-Irvine Metropolitan Division (Orange County) remains good. Its economy is expected to outperform the U.S., although the lead will be much narrower than that seen in the first half of this decade.

• The loss of housing as a driver of the economy is one factor. Another is the end of accelerated defense spending, which will make aerospace a stable but no longer expanding industry in Orange County.

• International trade, technology-producing industries and tourism will continue to support the economy over the long term.

• Economic diversification has shielded the economy from potential risks. Household income is among the highest in the nation, supporting retail and local services. Orange County’s economy is expected to perform above-average over the long term.

MARKET DEFINITION The Los Angeles-Long Beach-Santa Ana Metropolitan Statistical Area (MSA) in Southern California is the largest of the three MSAs within the Los Angeles Combined Statistical Area (Los Angeles CSA), which also includes the Riverside-San Bernardino-Ontario and Oxnard-Thousand Oaks-Ventura MSAs. The Los Angeles-Long Beach-Santa Ana MSA is further divided into two metropolitan divisions—Los Angeles-Long Beach-Glendale and Santa Ana-Anaheim-Irvine. The Santa Ana-Anaheim-Irvine metropolitan division, which is the subject of this analysis, consists solely of Orange County and encompasses 34 incorporated cities.

CURRENT TRENDS The Orange County economy is expanding, however its pace of growth has moderated since mid-year 2004. Job growth no longer exceeds the national average, but income growth is projected to lead both the U.S. and California. Supporting the economy are stable manufacturing industries, as indicated by estimated industrial production rising well ahead of the U.S. average. Travel and tourism as well as aerospace industries create stable growth for this region. The pace of growth has slowed, but not decreased, as indicated by a leveling of the trade sector and a moderate downturn in financial services. Near-term prospects for Orange County’s technology-producing industries remain good. Employment in the aerospace and defense sector are benefiting from the state’s increase in defense contracts in 2005 and a demand for commercial aircraft. Office-space using employment has flattened as of year-end 2006 but is expected to increase by mid-year 2007. Office vacancy rates maintain record lows despite a slight increase. To accommodate the demand, record levels of construction permits have been issued over the past year, and construction of new office space is underway. The increase in construction of new office space is anticipated to keep rental rates affordable. Construction employment will benefit from both residential development and from the extensive commercial projects in the pipeline. House-price appreciation has slowed to less than 10 percent over the year, and the volume of sales has declined in recent months. Yet even with slower appreciation, affordability is at its lowest point since 1983, indicating a severe imbalance between household income and home prices. Thus, even with moderate job growth and only a moderate imbalance between supply and demand, prices could fall as buyers balk at the higher prices and higher interest rates. ECONOMICS Historically, Orange County’s gross metro product (GMP) has exhibited considerably greater volatility than the nation’s Top 100 metro areas (Top 100). In the following exhibit and all subsequent time-series graphs, the shaded bars indicate the periods of a U.S. economic recession. The Top 100 Metro Areas are comprised of the 100 largest metropolitan statistical areas within the U.S. in terms of total employment as of 2006.

• Orange County’s annualized growth for GMP of 5.7 percent between 1996 and 2006 exceeded that of the Top 100 average annual GMP rate of 3.7 percent.

• The projected growth in the Orange County economy at 2.9 percent annually through 2011 is greater than that of the projected growth of the Top 100 Metro Areas of 2.7 percent annually.

ANNUALIZED POPULATION GROWTH BY MSASanta Ana-Anaheim-Irvine MD

1996 – 2011

Demographics are a challenge over the long term for Orange County, as population growth shifts to the more inland regions of southern California. Orange County’s rate of population growth is constrained not only by very high business and living costs, but also by a limited amount of space for new home construction and low housing affordability. Orange County ranks highest in median household income among the Los Angeles CSA’s counties.

• Orange County’s 2006 estimated median household income was $67,300, 25 percent higher than the Top 100 median of $53,900.

• Over the past 10 years, Orange County’s 3.8 percent average annual growth in median household income was one-half of a percent higher than the Top 100 average annual increase of 3.3 percent.

• Through 2011, Orange County’s median household income is expected to grow an average of 3.2 percent per year, higher than the projected Top 100 average of 3.0 percent.

Orange County’s most significant concentrations of households with median incomes over $100,000 per year are located in the more sparsely populated northeast area near Yorba Linda and Placentia, within the southeast in Santa Margarita, and along the south coast from Newport Beach to Laguna Beach. Among the more densely populated communities, Costa Mesa and Newport Beach have the highest median household incomes. The north and west portions of the county are predominantly populated by middle income households.

Source: Claritas, Inc., Cushman & Wakefield Analytics

MARKET COMPETITIVENESS Orange County continues to attract a well-educated, affluent population, and is the Los Angeles region’s most diverse economy in terms of industry sectors.

• International trade with Asia in particular has resulted in Asian firms expanding into Orange County and establishing their U.S. headquarters offices within the region.

• Orange County is well-positioned to benefit from an accelerating global economy, particularly the Pacific Rim economies, which should deepen demand for electronics and tech equipment.

• While Orange County’s costs of doing business and living are high, its excellent quality of life is often considered conducive for top-level operations.

• The high costs of living and doing business generate some friction for long-term growth, but this is offset by the high quality of Orange County’s labor force, and the area’s good quality of life that make the area a good home for high-value added production of goods and services.

• Downside risk comes from Orange County’s exposure to the housing market. Should the housing market plummet under high interest rates, broad employment losses in the financial services sector are likely to follow.

CITY DESCRIPTION "City of Irvine"

The subject property is located in the northern portion of the City of Irvine, just southeast of the former Tustin Marine Corps Air Station. The subject’s city and neighborhood are within an area commonly referred to as the Greater Airport Area. At the end of World War II, most of the land near John Wayne Airport was either vacant or used for agricultural purposes. Following World War II, several large aerospace companies built sprawling defense and research and development facilities in the area. For example, Ford Aerospace and Communications opened a 99 acre plant, on land leased from the Irvine Company, in Newport Beach in 1960. Demonstrating the area's continued transition from high technology and defense employment, this plant, which sold to Loral Aeronautics in 1990, closed and is being redeveloped with estate homes. The district's manufacturing plants were spawned by the area's favorable climate, low land costs, and proximity to Marine Corps Air Stations (MCAS) El Toro and Tustin. MCAS El Toro and Tustin were established during World War II. Camp Pendleton, which is the largest amphibious training base in the world, forms the southern boundary of the County and is home to the First Marine Division. Both MCAS Tustin and El Toro were recently closed as part of downsizing the American defense system. The Airport District is the most expensive commercial and residential district in Orange County, and is the county's largest employment center. The district consists of the cities of Costa Mesa, Irvine, Santa Ana, and Newport Beach. The focus of this district is John Wayne Airport. ACCESS AND TRANSPORTATION The City of Irvine is served by the Southern California freeway system. The San Diego (I-405) Freeway extends in a northwest-southeast direction through the central portion of the city. The Costa Mesa (SH-55) Freeway runs in a northeast-southeast direction along the western edge of the city. The Santa Ana (I-5) Freeway, situated approximately five miles north of the subject, runs in a northwest-southeast direction. Additionally, the SH-73, San Joaquin Hills Transportation Corridor, extends along the southerly portions of the city. Irvine offers specific transportation advantages for servicing the industrial and commercial markets with direct freeway links with downtown Los Angeles, Long Beach, San Diego and Orange County. Irvine is serviced by three major railroads: Santa Fe, Southern Pacific, and Union Pacific. The closest of these lines to the subject are the Southern Pacific and the Santa Fe Railroads. The railroads provide daily scheduled service to all transcontinental points with 24-hour switching service, reciprocal switching agreements, "piggy-back" service, and passenger service. The area is also served by AMTRAK and Metrolink. There are 14 local and long distance trucking lines serving the region. Greyhound Lines

Household formation in the subject’s three-mile radius is projected to increase by 2.14 percent during the next five years to 2.86 persons per household. INCOME Irvine has a 2006 average household income level of $107,885, which compares favorably with the Orange County average household income level of $89,328 and the State of California level of $74,936. Irvine also has a relatively high proportion of upper income households, with 41.11 percent of all households having an income level of more than $100,000 annually. The 2006 average household income in the subject’s three-mile radius is $90,215.

EMPLOYMENT AND LABOR BASE The City of Irvine is home to approximately 9,800 businesses and approximately 168,000 employees. The unemployment rate is 3.4 percent. Major employers in Irvine include the University of California, Irvine (11,350 employees), St. Johns Knits (2,900 employees), Toshiba (2,500 employees), Irvine Unified School District (2,400 employees), and Verizon Wireless (2,300 employees). Irvine is also home to a world-class research institution at the University of California, Irvine, which has attracted a number of companies to this area, including Toshiba, Sony, Gateway, Oracle, Johnson & Johnson, Medtronic, and Allergan. The majority of the workforce is employed in the office sector (64%) with remaining workforce employed in the industrial sector (24%), institutional sector (6%), and retail sector (6%). The unemployment rate for the City of Irvine compares to 3.3 percent for Orange County and 4.4 percent for California. While most cities in Orange County experienced increases in unemployment rates during the recession, the City of Irvine improved. This increase is primarily attributed to increasing job opportunities in the textile/apparel manufacturing sector and transportation/utilities sector. subject neighborhood The subject is located on Corporate Park, which is basically a “loop” street improved with low-rise office buildings. Corporate Park is situated just off (easterly) Jamboree Road, and also “backs” to Barranca Parkway to the north. The subject is located just east of a retail strip center which is accessed off Corporate Park and Barranca. The tenants include several smaller restaurants/fast food restaurants including Arby’s, McDonalds, El Pollo Loco, and a Japanese restaurant and a sandwich shop, as well as several convenience tenants including a dry cleaners, photo shop, and a salon. The former Tustin Marine Air Base is located diagonally northwest across the intersection of Jamboree Road and Barranca Parkway. Portions of the site are being developed with a major retail center at this location. In addition to the projects above, the City of Irvine recently annexed the former El Toro Marine Base in southern Orange County, which is proposed for development as a Great Park. The proposed plan includes several thousand acres of open space, 3,400 homes, and 800 senior housing units. CONCLUSION The subject's location within the City of Irvine is a positive influence on its value. The property is located a few miles north of the City of Newport Beach and competes within one of the most prestigious office markets of Orange County. The subject's location is considered desirable based on the factors identified below:

• Employment in the area is strong. The Irvine Business Complex and the Greater Airport Area of Orange County have led the county in employment growth during the past decade.

• Transportation linkages to the area are convenient. Interstate-405 (San Diego Freeway) is 1.5 miles south of the subject.

Large, natural open spaces within the Santiago Hills lie to the north, and the community of Foothill Ranch is located east of the project site. The subject is approximately 45 miles away from Downtown Los Angeles. Regional access is provided via Interstate 5 (I-5) in a northwest/southeast direction, Interstate 405 (I-405) in a southeast direction, and the State Highway 133 (SH-133) in a northeast/southwest direction. The project site is adjacent to the meeting point of two major freeways, as well as a significant state highway that runs from the Pacific Coast Highway in Laguna Beach to its junction with State Highway 241 (SH-241). PROJECT BACKGROUND AND ENTITLEMENTS The subject property represents a portion of what was the Marine Corp Air Station El Toro (MCAS El Toro). The decision to close MCAS El Toro was made by the Department of Navy (DON) under the Base Realignment and Closure Act in July, 1993. Since that time several plans for the reuse of the site have been prepared by various entities including the County of Orange, El Toro Reuse Planning Authority (ETRPA), and the City of Irvine. The current plan, called the Orange County Great Park Plan, is consistent with the concept for reuse of El Toro approved by the voters of Orange County in the March, 2002 initiative (Measure W). The Measure W initiative resulted in the designation of MCAS El Toro for park, open space and other uses and incorporating the site into the City of Irvine. On April 23, 2002, shortly after the passage of Measure W, the DON announced its intention to sell the property by public auction in accordance with federal surplus property disposal procedures. Following the DON decision to sell the land at public auction, the City of Irvine developed a concept plan to assure that the orderly development of the “great park” consistent with

the Measure W initiative could be realized through the private sector. The objective of the Orange County Great Park Plan was to allow a reasonable economic return to the private sector buyer while assuring park, open space and other public areas would be dedicated to the City or other non-profit or governmental entity in perpetuity and improved without cost to the local taxpayer. The City prepared a land plan that would allow for increased development intensities in exchange for the private sector participation in a development agreement that required the full dedication and improvement of public infrastructure and open space amenities. The City’s strategy was to allow for intensified private development under a Development Agreement arrangement in return for dedication of lands to be used for park, open space and public and institutional purposes. The City also created a less intense development plan as the base/underlying zoning designation which would allow for the future private sector owner to decide for itself as to whether or not to pursue the more development intense overlay zoning through a development agreement.

Appraisal Note: The name of the master-planned community – Heritage Fields – was established by the current ownership subsequent to its purchase of the property from the DON. The planning framework for the project that was set out by the City of Irvine refers to the subject property and the adjacent park land/open space collectively as The Great Park. The EIR, for example, evaluates the subject MPC and the public park collectively, and the project is dubbed Orange County Great Park. On July 8, 2003, the Irvine City Council adopted Ordinance No. 03-19, approving the original version of the development agreement and on July 1, 2004 the Planning Commission of the City held a public hearing, after certain findings and determinations had been made in regards to the development, recommending the City Council that the earlier agreement be approved. On October 12, the City Council also held a public hearing and adopted Ordinance No. 04-13, approving the earlier version of this agreement. Upon completion of the bidding process and the purchase of the property, in 2005 the city sought to revise the 2004 version of the Development Agreement and on May, 5, 2005 the Planning Commission held a public hearing for the new agreement and recommended its approval.

2005, the City Council also held a public hearing for the new agreement and on May 24, 2005 adopted Ordinance No. 05-10 approving the new agreement.

The purchase of the former Marine Corps Air Station at El Toro took place in early 2005 by Heritage Fields, LLC. The land was subsequently transferred on July 12, 2005 from federal control to Heritage Fields, which voluntarily entered into a Development Agreement with the City of Irvine that guaranteed limited development rights in return for a package of land dedication and fees to be used by the City to develop the Orange County Great Park. Development Agreement – The document governing the development of the Heritage Fields project is a Development Agreement entered into by Heritage Fields, LLC and the City of Irvine. The DA guaranteed Heritage Fields, LLC development rights for the project in exchange for a package of land dedications and fees that are to be used by the city to develop The Great Park. Per the terms of the DA, Heritage Fields, LLC has the rights to develop 3,625 residential units and 5.3 million square feet of commercial uses. The City of Irvine receives approximately $672 million in development fees as follows:

$200 million Development Agreement Fees

$201 million Community Facilities District (CFD) bonds

$191 million Redevelopment Tax Increment (RDA TI)

$80 million Housing Set Aside Funds

It should be noted that Heritage Fields, LLC is proposing a series of changes to the DA. Under the terms of the DA, any changes to the plan may be proposed by the City and agreed to by Heritage Fields, LLC; however. According to the developer, in the fall of 2006, the Irvine City Council appointed a Committee composed of Mayor Krom and Councilman Agran to negotiate any proposed changes in the DA with Heritage Fields, LLC. The proposed changes to the plan include increasing the residential unit total by 5,875 for a total of 9,500 units. The commercial space would be reduced by 30 percent or 1.6 million square feet to a total of 3.7 million square feet. The proposed Amended Plan would also include the dedication of an additional 402 acres of land to the city including a 211-acre golf course, 131 acres in the Exposition Area, and 60 acres for affordable housing. This appraisal makes reference to the proposed Amended Plan, which is currently being considered by the City of Irvine and Heritage Fields, LLC, as the proposed modifications would have significant implications for the overall project if adopted. However, as of the date of value, the timing and the ultimate outcome of the proposed modifications is uncertain. As a result, we have not specifically analyzed the proposed modifications but have considered the potential benefit of the increase in project yield in the “as is” value discount rate selection.

PRODUCT AND PHASING PLAN The 2007 Adopted Business Plan (ABP) for Heritage Fields provides the projected completion/land sale dates for the specific developments within each district. The timing referenced herein is based on the developer’s plans and does not necessarily correlate to the absorption schedule employed in our valuation. In the Lifelong Learning District, the cemetery is expected to be sold by September of 2007; there is a contract in-place for the cemetery. The developer contemplates that the first 139 single-family detached homesites are expected to be completed by June 2008 along with approximately four acres of retail in the south central portion of the district. By the end of 2008, another 136 homesites are anticipated for completion in addition to 30 acres of R&D. Per the ABP, in 2009 another 366 homesites are expected to be completed in the district as well as 2.5 acres of R&D, almost 10 retail acres, and 82 educational acres. In 2010, Heritage Fields is projecting the completion of 254 additional homesites, and the sale of approximately 100 acres of educational land and 160 acres of agricultural land in addition to 36 acres of R&D land. In 2011, the final 131 homesites, 26 educational acres, and the Expo Center are expected to be delivered/sold. According to the ABP, in the Park District the completion of 548 homesites is forecast for 2008 - 442 by June and the remainder in December. In 2010, another 269 homesites are planned for completion. The Golf Course is projected for delivery in 2011 along with an additional 62 homesites. In 2012, 94 homesites are to be completed followed by the final 70 the following year. Per the ABP, the Transit Oriented District is to experience significant activity through 2011. In 2007, 512 homesites and 6 R&D acres are projected for completion/sale. In May of 2008, 16.1 auto center acres are anticipated and in 2009 approximately 11 R&D acres, 11.6 auto center acres, and 12.5 agricultural acres are planned. In 2010, 50 R&D acres, 891 homesites, 10.5 office, and 6 retail acres are to be completed. In 2011 the final 46.6 R&D acres are scheduled for sale. The final 47 homesites are anticipated to be delivered in 2012. AFFORDABLE HOUSING REQUIREMENT Per law, a minimum of 15% of the total home count must satisfy affordable housing requirements. Because the property is located in a redevelopment district, 6% must be available for families qualifying for Very Low-Income Homes (VLIH), 4% for Low-Income Homes (LIH) and 5% for Moderate-Income Homes (MIH). As a condition of the Navy’s auction process, the LLC entered into an agreement to construct a total of 165 homes for families in transition (e.g., homeless). It is assumed that the 165 homes will not qualify for affordable housing, i.e., will not be a credit against the 15% requirement. In accordance with an executed agreement with homeless service providers, a 22.2-acre site (L24) is assumed conveyed for “transitional housing.” The current agreement anticipates that the site for the 165 transitional homes would be within

the 215.7-acre Exposition Center area (L27), but the service provider, ETHIC, has stated an interest in being located with the Long-Term Learning District (LLD). VLIH and LIH requirements are to be met by conveying 18.8 acres of land (T10a) to the City’s Affordable Housing Trust, with required homes constructed by the Trust using RDA housing set-aside funds. MIH requirements are to be met by the construction of market-rate apartments, the intend being no reduction in land value for the apartment site (T8). Further, a total of 60 homes for faculty and staff are to be constructed on a LLD site (L10).

AFFORDABLE HOUSING SUMMARYHeritage Fields (El Toro MCAS)

The current proposal meets, and essentially over-mitigates, for the affordable housing requirement, which is 544 affordable homes (3,625 units x 15%). The four planning areas discussed have not been designated as land sale revenue events in the developer’s business plan and the appraisers have assumed the same, understanding that such sites are often conveyed to various affordable housing development entities with no effective land basis possible due to the high cost of constructing affordable housing and feasibility standards. EXISTING LAND USES The former MCAS El Toro base was developed in 1942 on land purchased from The Irvine Company. The former base operated continuously as a military air facility from that time until it was closed in July 1999, as part of the federal 1993 Base Realignment and Closure (BRAC) process. Since closure, existing buildings, structures, ancillary facilities, runways, etc. have been left on-site. Portions of the site are also currently used for agricultural operations. The current ownership is leasing some of the existing facilities for various interim activities, such as the golf course and equestrian facilities and the Cal State University, Fullerton Extension Campus, agricultural operations, and recreational vehicle storage. The former MCAS El Toro base generally consists of approximately 500 existing structures with approximately 4.6 million square feet of space. There are approximately 1,100 existing former military housing units. Development includes the MCAS and COMCABWEST headquarters building and the officers club, unoccupied residential housing, maintenance, operation, and storage uses, the airfield

operations building, an equestrian center, golf course and industrial uses, with predominantly hangers and warehouses. The former base airfield also included five runways. It is our understanding, through conversations with the current ownership, that some of the existing improvements may have re-use potential within the context of the master-plan. However, the primary strategy for the ownership is to implement a land development/lot sale program consistent with the planning and zoning framework for the Heritage Fields project. Therefore, we have not considered the contributory value, if any, of the existing improvements. SURROUNDING USES Surrounding land uses include the Irvine Spectrum business park, Wild Rivers Water Park and the Verizon Wireless Amphitheater to the southwest, industrial/business parks to the southeast, residential neighborhoods to the west within the City of Irvine, residential neighborhoods to the southeast within the City of Lake Forest, and agriculture and open space to the northeast. TOPOGRAPHY The majority of the subject property has little topographic relief, with a slight slope (1.5 to 2.5 percent) to the west and southwest, and a gently sloping to steep hillside area at the eastern section of the site. Elevations in this portion of the project area range from approximately 200 feet above mean sea level (MSL) at the western corner of PA 51 to approximately 450 feet above MSL on Irvine Boulevard at the Wherry Housing Area and rising to over 750 feet above MSL at the eastern corner by the Foothill Transportation Corridor. The Santa Ana Mountains are north and east of the property and rise to 6,698 feet above MSL. The San Joaquin Hills south of the site rise to approximately 1,170 feet above MSL. The area south of Barranca Parkway has moderate slopes ranging from five to 20 percent. The site’s southwestern slope is interrupted by the manmade undulations at the Marine Memorial Golf Course (southeastern section) and the drainage areas along this course. The topography of the subject property does not present an obstacle to its future development. ACCESS AND CIRCULATION The project area is located north of the Santa Ana (I-5) Freeway, east of the Eastern Transportation Corridor (SR-133), and south of the Foothill Transportation Corridor (SR-241). Major roadways bordering the project area include Barranca Parkway to the south, Sand Canyon Avenue to the west, Portola Parkway and Irvine Boulevard to the north, and Alton Parkway to the east. The Irvine Transportation Center, a major multimodal transit center linking Orange County Transportation Authority (OCTA) bus, Metrolink commuter rail, and Amtrak rail services, is adjacent to the Southern California Regional Rail Authority (SCRRA) tracks, which bisects the area of the subject property.

The subject property is serviced by a series of significant roadways. The Eastern (SR-133) Transportation Corridor is located to the west and travels in a northwest-southeast direction. The Foothill (SR-241) Transportation Corridor navigates the northern section of the project site in a southeast-northwest direction until intersecting with the SR-133 just north of Portola Parkway. Portola Parkway is a sizeable highway to both the east and west of Jeffrey Road. Irvine Boulevard travels in a northwest-southeast direction through approximately the center of the project site. Sand Canyon Road crosses under the I-5 and intersects with Portola Parkway, Irvine Boulevard, and Trabuco Road, while running parallel the SR-133 on a northwestern border of Heritage Fields. Alton Parkway and Barranca Parkway venture along the perimeter of the former El Toro Golf Course and Bake Parkway is a major north/south roadway just east of the Heritage Fields project. The subject property is very well served by the regional transportation network and has access to mass transit. Overall access and internal circulation, upon completion of the project infrastructure, is considered very good. UTILITIES WATER Irvine Ranch Water District (IRWD) is the jurisdictional agency responsible for providing domestic water service to the Specific Plan area. According to the EIR, the IRWD does not have any adopted expansion plans for the potable water system within the project area. The Metropolitan Water District of Southern California (MWD) is planning for a parallel pipeline to the Allen-McColloch Pipeline (AMP), which currently traverses the EIR project area. The City of Irvine acknowledges that only existing infrastructure that meets current IRWD standards will be preserved for use in the future. Infrastructure considered below the IRWD standard will be replaced and/or upgraded based on IRWD recommendations during implementation of the Heritage Fields project. The IRWD will have sufficient water supply to serve the subject property. SEWER The Irvine Ranch Water District (IRWD) operates the Michelson Water Reclamation Plant (MWRP) located off Michelson Drive in the San Joaquin Marsh. The IRWD is a member of the County Sanitation Districts of Orange County (CSDOC) and is capable of conveying all sewage flows not treated at the MWRP to CSDOC facilities in Fountain Valley for treatment and disposal. The IRWD does not anticipate problems in supplying wastewater service to any current and future development in the City of Irvine. The subject project, therefore, will be sufficiently served by municipal sewer. SOLID WASTE Solid waste is collected by private waste haulers in unincorporated areas of the County. Solid waste generated at the subject property is collected by Waste Management Inc., a private solid waste hauler. Waste Management Inc. is also one of the private hauling firms permitted to work within the City of Irvine. Solid waste collected at the subject property is currently disposed of at the Frank R.

Landfill. The County of Orange Integrated Waste Management Department (IWMD) owns and operates the facility. STORM DRAINAGE Regional flood control and drainage systems exist throughout the vicinity of the Heritage Fields project area. Presently, the Eastern/Foothill Transportation Corridor, Partola Parkway, Irvine Boulevard and Jeffrey Road have major storm drain systems. Sand Canyon Avenue and Trabuco Road have no major drainage facilities. Of the five existing regional storm water basins relevant to the project site, no modifications are required except for the Marshburn Basin which will require the construction of the ultimate intake and outtake systems. The EIR determined that with the implementation of various mitigation measures storm water, flood plains, and groundwater impacts were deemed less than significant. For further details, it is recommended that the reader refer to a copy of the Final Environmental Impact Statement/Environmental Impact Report and Addendum. POWER Southern California Edison (SCE) is the jurisdictional agency currently responsible for providing electricity service to the area. A “The Orange County Great Park Program EIR Infrastructure Report” (Fuscoe Engineering, November, 21 2002) was prepared to design the backbone infrastructure system. This report is provided in Appendix J of the Final Program EIR. It is our understanding that in connection with the development of the Heritage Fields project, the existing electrical system will be replaced and the new system will comply with modern design methods, performance standards and specifications. The new system will be installed to generally coincide with the routing of new and existing roadways circulating throughout the project. Electrical lines will be required to be undergrounded pursuant to City standards. NATURAL GAS Southern California Gas Company (SCGC) is the jurisdictional agency currently responsible for providing natural gas service to the area of the subject property. The new on-site gas distribution infrastructure can be connected to and served from the existing SCGC infrastructure mentioned previously. The existing SCGC facilities are located within and adjacent to the subject property. The new gas distribution facilities will typically be installed in the right-of-ways of existing and proposed streets and will be located to efficiently meet the needs of the project. The new gas distribution systems will utilize current design, construction, and operating standards to meet the energy distribution needs of the proposed project. TELEPHONE The project site is located within the service area of Pacific Bell. Pacific Bell has existing telephone facilities within the vicinity of the subject property. Facilities exist near the intersection of Irvine Boulevard and Jeffrey Road and near Portola Parkway. Pacific Bell will need to extend/enhance existing facilities in order to accommodate the project. PacBell is capable of such an expansion.

CABLE TELEVISION CoxCom, Inc. is the cable franchise currently providing cable television service to the subject property and the vicinity. The provider will be able to accommodate the needs for cable service for the project during buildout and upon completion. PUBLIC SERVICES FIRE AND EMERGENCY MEDICAL The subject development will be served by The Orange County Fire Authority (OCFA). OCFA provides fire protection and paramedic services to the City of Irvine, and 19 other jurisdictions. The subject property and vicinity are currently served by OCFA stations No. 20, 26, 36, 51, and 38. There is one operational fire station on the former base (Station No. 20). Station No. 20 provides fire protection service to both the former base property, as well as the surrounding off-base properties. LAW ENFORCEMENT The subject development will be served by the Irvine Police Department in Central Irvine.

EASEMENTS AND / OR ENCROACHMENTS The developer provided a title report (Order No. 7002439-23) prepared by the North American Title Company, dated December 7, 2006. The report is included in the addenda. There were numerous listed exceptions, primarily utility easements. No significant adverse easements, conditions, or encroachments, which were deemed to have a substantial impact on value, were noted upon review of the report or during the onsite inspection. The property was appraised assuming clear title and no unknown easements or encroachments. A full title review is recommended. SEISMIC HAZARDS According to the Environmental Impact Report, the project area is located in the seismically active Southern California region. There is no known active or potentially active fault crossing or projecting into the project area. Ground shaking has been experienced in the past and may occur in the future. The site has a low susceptibility for liquefaction because the alluvial sediments are relatively coarse and the water table is generally more than 80 feet below the ground surface. In order to assess the geologic/seismic risk associated with potential development, the City evaluates five general types of geologic conditions through Seismic Response Areas (SRA). SRAs describe the different types and magnitudes of potential seismic hazards, making it possible to evaluate the risks of property damage, personal injury, and loss of vital services which may result from an earthquake. The majority of the subject property is located within SRA-2. SRA-2 consists of denser soils/deeper ground water. The primary potential seismic hazard in this area is ground motion. The majority of the project area is within SRA-2 and is considered suitable for development. The northeastern portion of the project area is located

within SRA-3 and SRA-4. SRA-3 consists of shallow alluvium over and abutting bedrock. In this area, the primary potential seismic hazard is ground motion. According to the EIR, many of the existing buildings on the former MCAS El Toro do not meet current seismic codes. Many are older structures that were constructed prior to seismic codes being in place or were constructed to federal military standards, not California Seismic Code standards. According to the EIR, the potential for fault rupture in the project area is extremely low, whether the project site is developed according to the land uses identified in the Base Plan or the Overlay Plan. According to the City of Irvine there are no known active or potentially active faults crossing or projecting into the project area. The project is considered geotechnically feasible. For further details, it is recommended that the reader refer to a copy of the Environmental Impact Report and Addendum. FLOOD HAZARDS According to the EIR, it is anticipated that project will not have a significant cumulative impact on water quality, nor would the project adversely impact the beneficial uses of the relevant water bodies. In a number of cases, post-development runoff from the project site is expected to improve, thereby potentially improving water quality over current conditions. Storm water and ground water impacts are summarized as not significant and, with city coordinated flood control improvements, the impact on flooding, erosion or siltation in the watershed is likewise deemed not significant. For Further details, it is recommended that the reader refer to a copy of the Final Environmental Impact Report and Addendum. HAZARDOUS MATERIALS The operation of facilities located in the former MCAS El Toro historically included many activities involving the use, storage, transfer, and disposal of hazardous materials. According to the Orange County Great Park EIR, during the approximate 55 years of military operation, air station activities, the operation and maintenance of military aircraft and automotive vehicles, required the use of a large variety of hazardous materials. These hazardous materials consisted of petroleum-based products such as aviation and vehicular fuels, engine and lubricating oils, solvents, cleaners, paints, thinners, pesticides and herbicides; chlorinated/halogenated compounds, including trichloroethylene (TCE) and polychlorinated biphenyls (PCB); some radioactive materials; ordnance munitions; and propellants. Use of these materials typically involves the generation of hazardous byproducts and waste. Many of the existing buildings and facilities may contain hazardous building materials such as asbestos-containing building materials (ACM) and lead-based paint (LBP). The DON was required to complete all necessary remedial actions before the fee title to the former MCAS El Toro was transferred from federal ownership. The federal government is also required to

conduct further remediation if additional contamination caused by DON actions is discovered or of a remedy fails to perform adequately subsequent to the transfer. The property, being a former US Navy facility, includes several so-called LIFOC (Lease In Furtherance of Conveyance) parcels which will be conveyed to the developer subsequent to final environmental clearance hurdles. This protocol is standard in base realignment and disposition scenarios such as the Heritage Fields project. It was assumed that environmental clearance and conveyance will proceed with no substantial obstacles that would alter the development plan as currently proposed by the master developer. The EIR outlines the mitigation measures that are required by the DON to remediate the adverse conditions on the subject property that result from the existence of hazardous materials on the site. Subsequent to mitigation, the EIR suggested that there would be no adverse impacts anticipated, as a result of the project, in relation to hazardous substances or the creation of any health hazards. The appraisers have no expertise in determining the existence of hazardous waste and are unable to make substantiated remarks in this field of study. It is assumed that any and all costs of potential mitigation measures are the responsibility of the DON. The appraisers’ descriptions and resulting comments are the result of the routine observations made during the appraisal process. For further details, it is recommended that the reader refer to a copy of the Final Environmental Impact Report and Addendum. BIOLOGICAL / ENVIRONMENTAL The subject property is located adjacent to the south of the NCCP Wildlife Reserve. The EIR and addendum report that the proposed project would not result in any direct impacts to the adjacent NCCP Reserve. Some indirect effects impacts include: intrusion of humans and domestic pets into the Reserve, predation of sensitive wildlife by domestic animals, increase population of species adapted to urban development (e.g. raccoons, opossum, and skunk) at the expense of more sensitive wildlife, increased fire risk and increased risk of invasion by exotic plant species. The indirect impacts associated with construction activities include potential erosion on exposed slopes, sedimentation of watercourses, dust accumulation on native vegetation and increased dumping of trash and other pollutants. The report concluded that implementation of the adopted mitigation measures will reduce all project-specific and cumulative biological impacts to a level of insignificance. For further details, it is recommended that the reader refer to a copy of the Final Environmental Impact Statement/Environmental Impact Report and Addendum. AGRICULTURAL RESOURCES The subject property is situated within an area with long-standing agricultural uses. The land use context is changing as agriculture becomes a less economically viable use of land. Areas of the subject property are currently utilized for farming and approximately 177 acres of the subject property are designated for agricultural land uses within the context of the master-plan we are evaluating in this appraisal.

The City is working to establish an Agricultural Legacy Program, which is intended to address the local and regional loss of agricultural land. The Program attempts to maintain agricultural lands for “metro farming”, which may include such activities as specialty farming, model farming, heritage farming, and community service/educational farming. Those areas within the subject property designated for agriculture could be suitable for such uses under the project zoning. Despite any City actions to zone land for agricultural uses on-site, the City does not have the authority to require landowners to continue farming operations on land that is zoned for agricultural use. The retention of agricultural land use designations on the site will not, therefore, necessarily result in the continuation of agricultural uses. For further details, it is recommended that the reader refer to a copy of the Final Environmental Impact Statement/Environmental Impact Report and Addendum. LAND DEVELOPMENT LAND DEVELOPMENT COSTS

The developer’s adopted business plan supplies income and expense estimates through 1st quarter 2015 reporting total master developer costs at $1,504,347,193 (untrended) and total revenues at $2,348,496,917 (untrended). Accordingly, the net cash flow is $844,149,724 (untrended). Note that substantial costs have been expended thus the $1,504,347,193 budget is over-stating remaining costs as of the date of value. Further discussion on projected revenues and remaining land development costs is presented in the “as is” valuation section of this report. DESIGN CRITERIA The subject site is a property of regional significance and is one of the largest remaining underdeveloped sites in central Orange County. The development plan encourages a mixed community of cutting edge technologies, research and job centers, which are integrated with learning, living, and recreational uses. The purpose of the urban design concept is to achieve aesthetic integration of uses within the site and with surrounding uses in the adjacent communities. The focus is to integrate anticipated land uses with existing facilities, and provide for architectural, landscape, streetscape, and site design enhancements to improve the character of the site. The existence of the Great Park, the proximity to permanent open space, and the orientation of the surrounding major access routes informs the formation of the three subject districts – the Park District, the Lifelong Learning District and the Transit Oriented Development District. As described previously, the plan for the Heritage Fields project is governed by the overall plan for the Great Park. The Heritage Fields project will be contained within distinct districts. The district structure concept addresses the major circulation corridors, entries into the site, the orientation of the districts relative to the Great Park and other site-wide design considerations that will provide an overall “look” or identity for each individual district.

The visual continuity throughout the Heritage Fields project will be created through streetscape design, entry features, and project landscaping. Edges of the planning areas shall transition to blend with the adjoining streetscapes. Landscapes between planning areas shall blend to avoid abrupt landscape edges. The intent of site planning is to integrate buildings and site improvements into a unified setting with minimal impact of the development on adjacent land uses. Site planning concentrates on the proper placement of buildings, roads, and services. MAINTENANCE PLAN Maintenance responsibilities for the common project facilities would be divided among a Master Homeowners’ Association, Neighborhood Associations, Community Service District, and/or similar maintenance mechanisms. For maintenance costs not covered by public services, the developer has yet to form a community-wide association with monthly assessments. Said assessments are expected to be consistent with competing projects. TAX AND ASSESSMENT INFORMATION Current California taxation law requires a 1% of market value tax rate, plus additional assessments determined through individual communities bond indebtedness (Proposition 13). Actual assessments are typically based on the market value, as determined by the most recent acquisition price. Future assessments will be based upon the most recent acquisition price until additional improvements (land and/or homes) are constructed onsite or a subsequent change of ownership of the property or portions thereof. Subsequent annual tax increases are limited to a maximum of 2% per year. Disposition of the property, as of the date of study, would place the subject under Proposition 13 guidelines. Historical taxes are not available for the subject parcels given the property owners were the federal government with tax exempt status. The following table summarizes the current (FY 2006) real estate tax assessments for the subject property. The information was obtained from the Orange County Assessor. The Assessor’s Tax Maps outlining the subject’s Assessor’s parcels. As of the date of value, the subject’s Assessor’s Parcels do not correspond to the parcelization set forth in the Tentative Tract Map summarized previously. Our review of the subject’s tax records and parcel maps suggest that there are a number of parcels that are not currently assessed. These parcels, in some cases, seem to correspond to what are not currently roadways or access areas.

Per the terms of the Development Agreement, the Developer shall form a Community Facilities District (CFD) for the issuance of bonds, the proceeds of which would be used to construct and/or acquire and maintain the Proposed Public Benefit Facilities and Services and levy a special tax sufficient to pay principal and interest on the CFD bonds and associated costs. The maximum amount of the CFD is $201,000,000. For the market rate housing in the Heritage Fields project, the developer has estimated an

overall rate of 1.75% to the homeowners. The active adult housing tax rate is slightly lower at 1.55%. For the commercial portion, the developer has estimated a tax burden of $4.00 per square foot of land (this figure is adjusted from the business plan, which includes $2.50 per square foot). Said tax rate would be fairly typical of most new larger master-plans in the area, which typically range from 1.10% to nearly 1.80%. Recent trends in property taxation laws seem to be of similar nature with no immediate changes anticipated. CONCLUSIONS Overall, the subject Heritage Field site was deemed to have very good development potential as planned. The property is one of the largest tracts of infill land remaining to be developed in Orange County. Both residential and commercial uses are situated near the property. Agricultural uses and significant open space are also adjacent to and incorporated within the project. The physical characteristics of the property are good for master-planned development. Employment centers, support facilities, and major transportation corridors (current and proposed) are within a reasonable distance from the property. The subject property benefits from an approved Development Agreement (contingent on conditions within the FEIR) which allows for 3,625 units, 6,585,594 square feet of commercial space, golf use, schools, and expo uses. As of the date of value, no physical or legal issues were apparent that would prohibit development to its highest and best use.

Detached housing priced above $750,000 made up 79% of the sales in the 1st quarter 2007. An additional 16% was priced slightly below in the $600,000 to $749,999 range. Only 4% of the sales activity was for housing priced $599,999 or below, however, this is due to the lack of available product rather than demand.

Most economists, builders, and other knowledgeable market participants anticipate a stabilizing trend in home prices in the short term. However, with the onset of less aggressive economic growth, and strains on housing affordability due to the rapid recent increase in home prices, there may be a moderate downward correction, which has been reported in more recent articles and surveys. NEW HOME SALES TRENDS Annual new home sales activity in Orange County has decreased in three of the last four years. From 2003 to 2005, total annual new home sales decreased nearly 9%± from 6,171 to 5,612 units (2005 had a slight increase over 2004). In 2006, total net sales were just over 3,500 units. As of the 1st quarter 2007, approximately 1,000 net sales were recorded, which if annualized, would suggest 4,000 sales by year end. Given the softening in demand, this figure is unlikely. Notable is a steady decline in the number of detached units sold annually, countered by a steady increase in attached units sold. These trends are seen as a combination of a general slowing trend in the market and also to the lack of available inventory. Historically, detached housing has made up the majority of sales in Orange County. As earlier noted, the number of attached projects has been increasing over the last few years due to increasing detached prices, demand for affordable housing, and a new regulatory climate governing the way lawsuits had previously discouraged attached housing developers. Given the increasing prices of traditional detached single family housing in Orange, Los Angeles, and West Riverside Counties, there has been and will likely continue to be growing demand for new homes in price ranges more consistent with small lot detached and attached housing, similar to the proposed product in the subject’s Heritage Fields.

SUMMARY – PRICING AND SALES ACTIVITY Product pricing trends had been generally positive up to about the 1st quarter of 2005, where in all categories of detached sale indicators have shown a potential for decline. Notable is that while the detached market has shown a decline in number of sales, the attached product has been on a general increase. Similarly, the subject’s Central submarket posted the highest price point over the past 3 years for both detached and attached product. A stabilization of pricing is anticipated over the next 12 to 24 months. A trend in sales velocity is not yet readily refined, however, based on recent surveys figures for 2007 indicate a slower year than 2006. Short-term projections are for a continuation of the “soft” market. Long-term projections, however, are for a positive trend in both pricing and sales activity with most knowledgeable market participants anticipating this market shift in 2008 or 2009. HOUSING SUPPLY OVERVIEW Hanley Wood reported that as of 1st quarter 2007, there were 335 units of unsold inventory in the 143 actively selling projects in Orange County. Unsold inventory defines product that has been released for sale but not yet sold and can be considered existing inventory. Another 5,540 units in active projects is considered remaining inventory or product that has received full approvals and has not been released for sale. This product may be under construction or pending construction and can be considered near-term inventory. Total existing and near-term inventory was 5,875 units. In addition, Hanley Wood reported that in

At the regional level, the continued reduced availability of land had allowed supply to decrease more rapidly than demand. However, the submarket’s level of detached units remaining for development (future construction) has remained fairly steady. The most recent number of remaining detached units (2,110) is up about 149% since the 2nd quarter of 2004, where there were 1,710 units remaining for development. The most dramatic trend is in the Central submarket, where there are currently 1,060 units remaining for development, up about 96% from 540 units in the 2nd quarter of 2004.

Over the same period, the future construction of attached product has grown dramatically from 1,374 units in the 2nd quarter of 2004 to 3,430 units in the 1st quarter of 2007 (a 1.50% increase). The Central Submarket had an even more dramatic increase from 472 units in the 2nd quarter of 2004 to 2,659 units in the 1st quarter of 2007 (a 463% increase). SUMMARY – SUPPLY Based on the inventory and sales data, it appears that the long-term trend in Orange County is for a steady supply of housing product. However, it appears based on affordable housing demand, attached product will continue to represent a larger portion of the overall housing inventory. Supply is the more inelastic factor in the supply-demand equation, and if demand remains constant in conjunction with the economic expansion being experienced, there is a potential for a shortage in supply. However, this is not anticipated in the immediate future given the 34,828± units in the planning stages. In the short-term, the large supply of housing, along with moderate decreasing levels of demand, should continue to result in product pricing sensitivity, especially in the Orange County market where there has been the emergence of several large simultaneously selling master-planned communities. Overall, inventory has been decreasing in both the larger Orange County market and in the subject’s Central submarket. The submarket continues to encompass a sizable portion of new housing in Orange County, averaging 28% of total unsold Orange County inventory in the 1st quarter 2007 period. There are 3,534 detached units and 23,426 units of attached units of future supply in the subject’s submarket. Considering actual active and proposed supply in reported projects, the figure is 26,960 detached and attached units. The long-term trend is for a steady supply of housing product with a possible decrease in submarkets with scarce developable land. In the short-term, the decreasing number of sales, along with moderate to declining levels of demand, should continue to result in product pricing sensitivity. To summarize, the current supply of detached homes is on the decline due mainly to the scarcity of available land, while planned and existing attached product is on the increase, due to the demand for a more affordable housing. Some softening in the market is seen as the general economy slows and consumer confidence wavers. Long-term demand, however, appears to be sufficient for planned construction. RESIDENTIAL DEMAND OVERVIEW POPULATION The California Department of Finance reported the Orange County population was estimated at 3,098,121 as of January 1, 2007. This represents a 0.9%± increase from the previous year’s population of 3,071,924. The greatest population growth in the county was seen during the 1980s as the population grew annually by 2.5%± on average. However, the high growth rate did not persist throughout the 1990s as the population grew by an average of 1.8%± annually by the year 2000. Since then the population has grown annually by 1.4%± on average. The county population is projected to continue to grow at an annual average rate of 1.4%± reaching 3,291,628 by 2010, and

The city's population is forecast to increase to 10,703, or 3.4%± per annum, by the year 2010. The majority of demand is anticipated to be a combination of internal Orange County household growth and additional households moving into the area from other areas of Southern California. Long-term forecasts indicate that population levels should continue to increase, thus substantiating the need, or demand, for housing.

EMPLOYMENT Historically, excluding 1993, the average unemployment rate for Orange County has been lower than the state and national rates. The county’s lowest average unemployment rate of 2.8% was attained in 1999, a year before the state’s and nation’s lowest average rates were recorded over the reported period. Since then, the county rate has been lower than the state’s and nation’s rates but generally closer than historical rates prior to 1999. The average unemployment rate for the county decreased to 3.5% in 2006, and was at 3.5% as of May of 2007, lower than the nation’s and state’s rates of 4.7% and 5.0% respectively.

United States California Orange County

Southern California Association of Governments projects steady employment gains for the Orange County region. Orange County is projected to increase its share of service employment approximately 0.9% annually over the 2000-2030 forecast period. The manufacturing sector share of total Orange County employment is expected to decline in this forecast period. Reportedly, a high number of tech jobs will be created around Irvine center in South Orange County. Wholesale, retail, and FIRE sectors are projected to slightly increase their shares of total county employment during the forecast period. As demonstrated in the following chart, employment levels in the Irvine area are forecast to increase at a slightly higher percentage than Orange County on a whole. At 1.3% annually, Irvine is forecasted to experience long-term projections of strong job growth. As economic expansion and development continues, the long-term projections are for continued increases in employment, which increases demand for housing.

Prime Rate 11th District Cost of Funds Freddie Mac 30-YR Fixed

Although difficult to predict over an extended period, mortgage interest rates continue to remain at levels allowing for consistent purchasing power by prospective buyers. Mortgage interest fixed rates on 30-year conforming loans and 1-year adjustable loans were recently at their lowest in 40 years but have been increasing of late. It should be noted that interest rates are projected to increase from record lows. As of the “as is” date of value, the prime rate was 8.25%, which has held steady since June 2006. The appraisers analyzed Orange County and the city of Irvine with regard to household income levels as shown in the following chart. The city of Irvine’s 2000 median household income was $72,057 per year.

This is more than the county, which had a median household income of $58,820. Within Irvine, 32% of the population earns over $100,000 per year while 33% earn less than $50,000 per year. The city income levels are expected to increase at a slightly greater rate than the county.

2000 HOUSEHOLD INCOMEHeritage Fields Master Plan, Irvine, California

Orange County

Given these figures, and anticipated price points for product in Heritage Hills, only a small portion of the submarket household could qualify for a home purchase in the project. However, these percentages do not account for households relocating from Los Angeles, Riverside, or San Diego counties. Further, these figures do not account for that portion of the population with sufficient cash or other assets to purchase a home without meeting the income criteria assumed in this analysis. Some prospective buyers in this submarket have diverse income and asset sources including older, more mature buyers with accumulated cash reserves. Buyers may also be moving up or down equity that effectively reduces mortgage payments. As evidenced by absorption of similar product in the submarket, there are a reasonable number of prospective buyers having sufficient purchasing power for the subject units, which translates into effective demand. CONCLUSIONS ON RESIDENTIAL HOUSING DEMAND Those factors typically gauged to determine demand for housing would indicate that demand in this submarket should continue at moderate levels. The population is increasing, steady gains in employment are forecasted, and interest rates are at acceptable levels. As discussed, growth rates are expected to continue in Orange County, Central, and Irvine submarkets. However, overall buyer motivation has slowed in the last year, while many factors such as population, interest rates, and overall business markets have remained strong. Although many potential buyers have the “ability” to purchase, they are not motivated to acquire given the latest softening in the market. Provided economic conditions do not deteriorate and/or interest rates do not increase substantially, demand for product in the submarkets should remain, which is further evidenced by absorption in area developments. RESIDENTIAL PRODUCT AND PRICING SUBJECT LAND USE The proposed land use plan was utilized by the appraisers in formulating product build-out and pricing scenarios. Lot sizes, master phasing, and project location essentially dictate the product segmentation.

family product (for sale units). The single family product (including zero lot line and courtyard homes) will be offered on minimum lot sizes ranging from 2,400 to 18,000 square feet. The attached product will be offered in projects consisting of medium and medium-high density condominiums and townhomes with densities of approximately 5.5 to 25.0 units per acre. Of note is that a variety of additional residential product will be offered, including faculty housing and moderate income affordable rental and for sale housing.

Per a review of the latest proposal, the Heritage Fields unit mix would include approximately 60% detached units and 40% attached units, not including faculty housing or affordable housing. Of the detached units, the mix is evenly weighted, with 52% of the lots having minimum lots sizes of 2,400 to 6,000 square feet and 48% having minimum lot sizes greater than 6,000 to 8,000 square feet. Of the 1,678 total multi-family units, approximately 70% are for sale condominiums and townhomes and 30% are rental apartments. The rental apartments include approximately 23% market rate units (117) and 77% affordable units (392). The total unit mix also includes 617 non-market units (17% of the total), including 60 faculty units and 165 units in the ETHIC planning area.

A likely project build-out would consist primarily of first-time and move-up housing for the smaller to mid-size production product and move-up or move-down housing for the larger production product. Preliminary base pricing and home sizes were provided for the residential product lines proposed by Lennar Homes (see proposed pricing summary table at the beginning of the Market Analysis section and below). The master developer utilized these preliminary product lines and projected the overall product build-out as summarized in the tables on the following pages. As shown, product would range from 1,125 to 5,900 square feet, with an overall average of 2,563 square feet.

PROPOSED RESIDENTIAL LAND USE SUMMARYHeritage Fields Master Plan, Irvine, California

The developer’s preliminary pricing for Heritage Fields is summarized in the following chart. The pricing was based on a preliminary market study for Heritage Fields prepared for the developer by Real Estate Economics (REE), dated December 2006. A subsequent market study of Heritage Fields, dated April 2007, was prepared by The Concord Group. The pricing recommendations for Heritage Fields by The Concord Group varied slightly from those provided by REE due to changes in the residential market from December 2006 to April 2007. The Concord Group’s market study, which provided the support for the appraisers’ home pricing assumptions, is discussed later in the Market Analysis section of this report. The

The ensuing discussion analyzes recent pricing trends in Orange County, the subject’s Central submarket, and comparative submarkets. This is followed by more specific pricing for active or recently active projects in master-plans and stand-alone subdivisions in these areas relative to the subject’s proposed pricing. ORANGE COUNTY NEW HOME PRICING OVERVIEW Based on a 1st quarter 2007 survey by Hanley Wood, the average new attached home price in Orange County was $540,365, or $383 per square foot. The Central submarket, with an average attached home price of $544,531 and $373 per square foot, was the 3rd least affordable submarket on an overall price and

a price point basis (per square foot) out of five submarkets. The $373 per square foot figure was 3% lower than the county average of $383 per square foot. Of note is that the average size of an attached home in the subject’s submarket was 70 square feet (5%) larger than the county average, which would explain, in part, the difference in price points as a larger size typically correlates to a lower price per square foot. An overview of detached product indicated an average new detached home price in Orange County of $1,162,420, or $367 per square foot. The Central submarket, with an average detached home price of $947,064 and $366 per square foot, was the most affordable submarket on an overall price and 2nd least affordable submarket (out of five submarkets) on an price point (per square foot) basis. The $366 per square foot figure was virtually identical to the county average of $367 per square foot. Of note is the average size of a detached home in the subject’s submarket was 552 square feet (17%) smaller than the county average. The smaller size typically correlates to a higher price per square foot.

NEW PRODUCT PRICING SUMMARY BY SUBMARKETOrange County

Detached Housing (Averages) Attached Housing (Averages)

The Central submarket represents a competitive submarket in Orange County when considering overall price, price per square foot, and home size. In general, the Central submarket is priced lower than the coastal submarkets and higher than the other inland submarkets, which would be expected given the relative desirability of the various locations.

The submarket’s central Orange County location, with a variety of pricing and price points, allows it to be competitive with the majority of competing submarkets that attract a similar buyer profile. The Central submarket is offering a mix of stand-alone projects and housing in larger master-planned communities with companion amenities such as new schools, parks, infrastructure, etc. Overall, the submarket’s central location near to major employment centers has resulted in similar to higher price points compared to most other submarkets within the Orange County region. CENTRAL SUBMARKET NEW HOME PRICING OVERVIEW The subject property is located in the city of Irvine in the Central submarket. Based on the 1st quarter 2007 active project survey by Hanley Wood, the average new attached home price in the submarket was $544,531, or $373 per square foot and the average new detached home price in the submarket was $947,064, or $366 per square foot.

Although specific average pricing data were not available for the city of Irvine, this city’s average pricing for detached and attached product is above the average pricing for the Central submarket due to the downward influence of other cities such as Tustin, Yorba Linda, Orange and Santa Ana on the overall submarket average pricing. The lower pricing of these cities compared to Irvine is expected given their greater distance from Irvine’s major employment centers and/or inferior quality product. ORANGE COUNTY DETACHED PRICING – BY LOT SIZE The price point research was further refined to reflect the regional Orange County detached product by lot size. As exhibited in the following table, the weighted average detached home price ranged from about $810,117 to $2,855,885 and $344 to $554 per square foot, depending on lot size category. Overall, the weighted average was about $1,338,000, or $393 per square foot. The weighted average home sizes ranged from 2,356 to 5,158 square feet. The data revealed increasing home prices on larger lot sizes, due to the larger home sizes that can be accommodated, and higher price points for the homes on larger lots due to the progressively better quality typically constructed. The median prices were slightly lower than the averages, ranging from about $797,000 to $1,538,000, or $1,229,000 overall. Based on the average absorption information, sales rates were generally consistent for all of the lot and product sizes, with slightly higher rates on the smaller lot sizes (lower prices) and slightly lower rates on the larger lots (higher prices), which would be expected due to the larger buyer pool and availability of product at the lower prices.

CENTRAL SUBMARKET DETACHED PRICING – BY LOT SIZE The price point research was further refined to reflect the Central submarket product by lot size. As exhibited in the following table, the weighted average detached home price ranged from about $757,000 to $2,085,000 and $316 to $553 per square foot, depending on lot size category. The overall weighted average was about $1,036,000, or $356 per square foot. The weighted average home sizes ranged from 2,090 to 3,770 square feet. The median price was slightly lower ranging from about $720,000 to $1,910,000, or $985,000 overall. Overall pricing generally increased with lot and product size. Atypical was the trend of price points (per square foot basis) increasing with lot and product size.

differences. Notable is that there was only one project within the largest lot size category and only 2 to 7 projects on the other categories, which tended to result in less conclusive data than for Orange County overall that had a larger pool of projects reporting information. Typical of market trends, however, the absorption rates in the Central submarket were generally higher for the lower-priced product and slower for the higher-priced product.

DETACHED PRICING SUMMARY BY LOT SIZE-CENTRAL SUBMARKET(1)

Heritage Fields Master Plan, Irvine, California

COMPETITIVE PROJECTS AND PRICING The reasonableness of the developer’s preliminary proposed pricing was investigated using several sources of information. As mentioned earlier, the developer’s preliminary pricing was based on a market study prepared for the proposed Heritage Fields master-plan by Real Estate Economics (REE), of Irvine, California, dated December 2006. However, of greater relevance to this appraisal was a subsequent market analysis for Heritage Fields prepared by The Concord Group, of Newport Beach, California, dated April 2007. The more recent market study provided a better indication of market trends as of the subject’s date of value. A copy of The Concord Group’s in-depth market study in its entirety (titled, “Market Analysis And Product Program Validation For The Heritage Fields Master-planned Community in Irvine, California”) is in the Addenda to this appraisal report. In addition to The Concord Group’s market study the appraisers also conducted a survey of actively selling and/recently sold out projects in the subject’s market area. The appraisers’ survey was utilized to ascertain the reasonableness of The Concord Group’s market study and to support reasonable indications of attached and detached pricing trends for the Heritage Fields Master-plan product. The Concord Group’s market study (“market study”) analyzed the primary market area (PMA) of Orange County, as well as several submarkets including the South Inland CMA that incorporates Irvine and the proposed Heritage Fields project. The market study surveyed more than 40 active projects in the subject’s market area. The results of the market study’s findings, as well as the study’s pricing recommendations for the subject’s proposed product types in relation to the active projects, are illustrated in the graphs on the next 12 pages. A location map showing the locations of the majority of the projects in the nearby master-plans follows the graphs.

The appraisers also surveyed active projects in the subject’s market area based on information provided through Hanley Wood Market Intelligence and our primary research as of April 2007 and May 2007. Nearly all of the projects surveyed by the appraisers were included in The Concord Group’s market study. The results of the appraisers’ survey are shown in Tables A (attached product) and B (detached product) that follow the market study graphs and location map. The information compiled in the appraisers’ survey (product size and pricing, minimum lot sizes, and absorption rates) was virtually identical to that in The Concord Group’s market study. Given the similarity in the information, the appraisers accepted the results of the market study survey information.

V A L U A T I O N S E R V I C E S 1 0 3

After analyzing the data, certain trends were noted. Compared to other Orange County submarkets, there were more attached and detached projects within the subject’s submarket, which was to be expected given its overall size and central location. Overall, the subject’s submarket had similar to higher price points than the North submarket and lower price points than the North Coastal submarket. This is expected given the subject is closer to employment centers than the North submarket and further from the coast than the North Coastal submarket. Within the subject’s submarket, projects within master-plan communities were similar to higher in overall price points than stand-alone projects. This is typical given the additional amenities and homogeneous living environment offered in master-plans. The market study charts show a fairly consistent trend in pricing from low to high for progressively larger home sizes and in price points from high to low for progressively larger home sizes. Notable in all the charts is that the developer’s pricing is in line with the competitive base pricing and price points. Overall, the market study’s attached and detached base subject pricing is in the upper half of the range when compared to the currently active projects within the submarket and surrounding areas. This would be expected given the subject’s excellent location and amenities that would warrant above-average pricing. The market study’s pricing estimates for the majority of the subject’s attached products are approximately 1% to 4% above the developer’s pricing, indicating a relatively strong demand for more moderate-priced housing compared to single family product. The Concord Group estimated lower pricing than the developer’s pricing for only two of the attached projects (luxury attached and triplex; product lines 3 and 9) at 1% to 5% lower, respectively. Overall, the developer’s preliminary detached base pricing was slightly high when compared to the currently active projects within the submarket and surrounding areas, which was supported by The Concord Group’s market study. With the exception of product line 16 (SFD 70 x 110 lots), the market study estimated pricing for all of the subject’s detached product types to be approximately 1% to 6% below the developer’s preliminary estimated pricing. The Concord Group’s estimated pricing for product line 16 is 15% higher than the developer’s pricing. After analyzing the subject’s competing market, The Concord Group’s pricing recommendations were within the price ranges for the active subdivisions in the area and were considered to be well supported. Thus, the appraisers accepted The Concord Group’s pricing recommendations for all of the subject’s product types. The home pricing assumptions used in this appraisal for the subject’s detached and attached product types, which coincide with The Concord Group’s recommendations, are summarized in the Market Value “At Completion” – Planning Areas/Parcels section later in this report. It must be noted that product lines 7, 8, 24 and 25 were not compared to the market given that product lines 7 and 8 are non-revenue generating product (ethic and faculty housing), and product lines 24 and 25 involve affordable units and have regulated set pricing.

ASSESSMENT RISK In addition to estimating pricing for the subject product types, The Concord Group also assessed the market risk for Heritage Fields, based on the health of the national home market, local employment trends, the subject’s competitive market area (CMA), the characteristics of the Heritage Fields project, and future supply trends. The risk assessment’s primary points are summarized as follows (details are in The Concord Group’s market study in the Addenda of the appraisal). In spite of the nationwide housing downturn, sales volumes in the subject’s CMA are healthy compared to the national average. Orange County is a major economic engine in Southern California, with consistent positive employment growth since 1994 and positive forecasts (albeit at a slower pace) for 2007 and 2008. During the past year approximately 40% of the county’s new home sales occurred in the subject’s CMA, with average new home prices approximately 10% higher than the county average. Prices and absorption rates have declined somewhat during the past year. Although builder home price concessions are prevalent, the concessions comprise a small percentage of the home prices. In regard to Heritage Fields, the project benefits from significant financial support from private and government organizations; the master-plan calls for a wide diversity of product that will create considerable synergy; the Great Park is envisioned as an iconic community landmark; and the lifestyle appeal of the Great Park and related amenities will provide a competitive advantage during market fluctuations. The risk assessment did note the potential for considerable additional units coming on line in the next several years, with several projects offering competition to the subject’s proposed product types. However, demand for new homes in Orange County is projected to remain strong over the next five years. The Concord Group’s overall assessment risk for Heritage Fields was 2.2 out of 5.0, or “low to moderate.” The reader is urged to review the market study in the Addenda to the appraisal. Product Line 1-Mid Rise Luxury Flats-(Planning Areas L11, L11a, L11b) Lennar Homes has proposed 271 mid-rise luxury flats with a weighted average product size of 1,125 square feet with estimated base pricing of $570,313, or $507 per square foot. The luxury flats are located in the Lifelong Learning District, adjacent to the Great Park and single family residences. A market study provided by the developer from The Concord Group dated April 2007 estimated an average base price of $575,000, or $511 per square foot for a 1,125 square foot unit. This product line is the densest project of the master-plan and offers minimal premium potential. After considering various elements relating to location and appeal, the developer’s proposed pricing for this product line was concluded to be inline with the market parameters for the subject’s Central submarket. Thus, the appraisers concurred with The Concord Group’s average base pricing of $575,000 or $511 per square foot for product line 1, which is 0.82% higher than the developer’s estimate. Product Line 2-Row Townhomes (Planning Areas L14b, L15, L22a-iii) Lennar Homes has proposed 232 row townhomes with a weighted average product size of 1,725 square feet with estimated base pricing of $743,750, or $431 per square foot. The townhomes are located in the Lifelong Learning District, adjacent to the Great Park, a luxury triplex and single family residences. A market study provided by the developer from The Concord Group dated April 2007 estimated an average

SUMMARY The appraisers’ projected base pricing generally followed the typical trend of higher pricing and lower price points for progressively larger homes. However, several product types on the largest lot sizes had price points at the upper end of the range due to the proposed high quality of the residences, consistent with other large lot subdivisions. In addition, several different subject product types are proposed for planning areas having similar lot sizes in order to minimize direct competition between the subdivisions. For example, Product Type 6 has an average proposed base price of $1,169,000, or $441 per square foot, on 6,300 square foot minimum lots, compared to an average base price of $1,510,000, or $382 per square foot, for Product Type 33 on 6,000 square foot minimum lots. The appraisers’ proposed product and pricing for the subject, based on the developer’s product proposal and The Concord Group’s pricing recommendations, were well supported per an analysis of the most competitive comparable projects. The subject’s estimated detached base pricing, shown in the following summary chart, ranged from $884,000 to $2,797,000, or $380 to $474 per square foot. It was noted that the highest price and price point were for Product Type 22 due to the large home size (average of 5,900 square feet) and better quality construction in this price range. The projected prices are higher than the average detached home price in the Central submarket of $947,064 and $366 per square foot, as well as that for Orange County of $1,162,420 and $367 per square foot. The subject’s estimated attached base pricing ranged from $575,000 to $916,000, or $407 to $511 per square foot. These prices are higher than the average attached home price in the Central submarket of $544,531 and $373 per square foot, as well as that for Orange County of $540,365 and $383 per square foot. The subject’s pricing would be expected to be higher than the averages for the submarket and the county given the subject’s master-plan location in Irvine and the above-average appeal that would be generated by the Great Park and other amenities (golf courses and open space) in Heritage Fields.

PRODUCT ABSORPTION ATTACHED PRODUCT Per the appraisers’ competitive project survey (Table A) monthly project absorption rates for attached product ranged up to about 16 sales per month. The average and median absorption rates for the 20 projects surveyed in master-plans were approximately 4 sales per month. The projects located in master-plans revealed a central tendency of between 3 and 6 sales per month. The absorption rates for the 20 stand-alone projects surveyed in Table A ranged up to approximately 15 sales per month, with an average and median of approximately 3 sales per month. The higher absorption rates in the master-plan projects were attributed to superior marketing and amenities that are generally associated with these types of large developments. Recent absorption rates (past 3 months) in both the master-plan and stand-alone projects were mixed, with an equal number of projects reporting slower absorption than the overall absorption rates (since opening for sale) as those reporting more rapid absorption than the overall absorption rates.

For the most part smaller, less expensive product sells more quickly than larger, more expensive product, which would be expected as effective demand is greater for lower priced product and decreases as pricing increases. In addition, there is typically a more limited supply of higher priced product, which is the case in the subject’s submarket and overall region. The Concord Group projected sustained absorption rates for each of the subject’s proposed attached product types, ranging from 4.0 to 6.0 sales per month, which was slightly higher than the absorption rates reported in the competitive projects. The appraisers concurred with the market study absorption projections for several reasons. The subject product will be located in one of the most appealing master-plans in central Orange County, with above-average amenities and excellent access and proximity to employment centers. In addition, the subject’s product is not anticipated to be available for sale until 2009 at the earliest. In spite of the relatively slow current market conditions, based on historical trends in the real estate market absorption rates could reasonably be expected to accelerate in the coming years. Thus, the market study’s absorption rate projections were considered reasonable and were accepted for purposes of this analysis. DETACHED PRODUCT Per the appraisers’ competitive project survey (Table B) monthly project absorption rates for detached product ranged up to about 6 sales per month. The average and median absorption rates for the 23 projects surveyed in master-plans were approximately 3 sales per month. The projects located in master-plans revealed a central tendency of between 3 and 4 sales per month. The absorption rates for the 4 stand-alone projects surveyed in Table B were considerably lower, ranging up to approximately 1 sale per month, with an average and median of less than 1 sale per month. Obviously, a master-plan location has a positive effect on a detached project’s absorption potential. As for the attached product, the higher absorption rates in the master-plan projects were attributed to superior marketing and amenities that are generally associated with these types of large developments. Recent absorption rates (during the past 3 months) in both the master-plan and stand-alone projects were mixed, with a similar number of projects reporting slower absorption than the overall absorption rates (since opening for sale) as those reporting more rapid absorption than the overall absorption rates. For the most part smaller, less expensive product sells more quickly than larger, more expensive product, for similar reasons as stated for attached product. The Concord Group projected sustained absorption rates for each of the subject’s proposed detached product types, ranging from 2.0 to 5.0 sales per month, which was slightly higher than the absorption rates reported in the competitive projects. Again, the appraisers concurred with the market study absorption projections due to the subject’s appealing location and amenities, and the likelihood of absorption rate increases in coming years based on historical real estate cycles. Thus, the market study’s absorption rate projections were considered reasonable and were accepted for purposes of this analysis.

PRODUCT ABSORPTION SUMMARY The appraisers’ absorption rate projections are summarized in the following chart. Consistent with market trends, the lower-priced product (attached and small lot detached) has the highest absorption rate projections, in a range of 4.0 to 6.0 sales per month. Several of the median lot size products also have above-average absorption rate projections. This reflects the appeal of single family detached housing in the subject’s market compared to attached product, in spite of somewhat higher base pricing. The slowest absorption rates of 2.0 to 3.5 sales per month applied to the higher-priced product on the larger single family lot sizes. The slowest rate of 2.0 sales per month was projected for Product Type 22, which has an average base price of $2,797,000 and an 18,000 square foot minimum lot size, consistent with market trends of slower absorption for higher priced product due to the limited number of qualified buyers. Effective absorption, which reflects the average sales rate based on the actual number of projected months of sales (from initial release to final closings; see planning area valuation section to follow), ranged from 1.95 to 4.86 sales per month, depending on the planning area and product type. The reconciled sustained and effective absorption rates were within the range indicated by the market data, which takes into account a continuing supply of direct competition to the subject, as well as the pricing and product delineation within the Heritage Fields Master-plan. Detailed absorption and development schedules for each planning area can be found in the Addenda.

Heritage Fields Master Plan, Irvine, CaliforniaMonthly Absorption

PLANNING AREA ABSORPTION AND CAPTURE Based on the master development phasing plan, critical path, proposed land use mix, and forecasted project absorption rates, a project sequencing schedule was formulated. The appraisers assigned anticipated prospective dates of completion for the individual planning areas/parcels. Prospective dates of completion were formulated so as to prevent substantial intra-project competition and to be compatible with the master phasing infrastructure construction plan. The development plan allows several non-competing projects to open simultaneously. With the wide variety of attached and detached product lines within the subject, there was only moderate direct competition amongst product lines. This strategy continues throughout the project life cycle for the various for-sale planning areas/parcels within each neighborhood.

The appraisers reviewed the master developer’s critical path in formulating the development timing for both revenues and costs. The developer re-confirmed that the timing in their latest plan remains fairly consistent with their expectations. The developer’s latest plan has residential land sale revenue events occurring from the 4th quarter 2007 through the 3rd quarter 2014. The appraisers considered the developer’s timing for the residential product reasonable and market supported given our estimates of absorption and capture. However, due to initial delays in development and delivery, the appraisers did move back residential land sale events scheduled for 2007 to the 1st quarter 2008. The schedule for remaining residential land sale events were similar to those presented in the latest plan, including various “rolling option” events for the higher-priced Park District planning areas.

The developer’s capture projections assume the overall community will be able to support an average of 600 market-rate home sales per year, plus affordable homes/rentals. A survey of larger area master-plans in the submarket indicated that capture rates, defined here as annual homes sales in a specific master-plan, have ranged from around 100 to over 500 units. Capture rates had been increasing since the recessionary years of the early 1990s, but have declined during the past year due to decreasing demand. Per a survey of market participants, most developers of larger master-plans anticipate an average of 200 to 400 sales per year. Said capture rates typically reflect sales from an average of four to eight simultaneous selling projects averaging 3.0 to 6.0 sales per month. However, depending upon the location and product, annual sales and the number of selling projects can be above/below these averages.

In 2005, the Central submarket of Orange County captured 2,807 net sales. In 2006, the figure was 24% lower at 2,128 net sales. In the 1st quarter, there were reportedly 596 net sales, which if annualized at the same rate would suggest nearly 2,400 net sales in 2007. Given softening demand, this figure is unlikely. If assuming the submarket averages 2,000 net sales per annum, the subject sales (market rate units) would encompass approximately 17% of the submarket (340 / 2,000). Given Orange County continues to approach build-out, this figure is substantiated. Heritage Hills will, in all likelihood, be one of only several active master-plans at the time its product becomes available and should have moderate competition. In addition, Heritage Hills will offer a diverse range of product types and sizes which should assist in above average absorption. Accordingly, the projected sales rate for the subject, per the formulated development and sales schedule, represented a reasonable rate of overall capture of the Central submarket and overall Orange County activity. Projections reflect average stabilized absorption and capture through the development period. As past years have demonstrated, however, housing markets are cyclical and projections over the long-term are conjectural.

CONCLUSIONS Market conditions and elements of supply and demand support the proposed residential land uses for Heritage Hills. The subject's submarket continues to exhibit moderate residential sales activity albeit with some softening in the last year. Demand is adequate to provide for reasonable absorption of new product provided the product is priced competitively and aggressively marketed. It appears the supply of housing in the Orange County market will be constrained over the coming years as the availability of developable land diminishes. However, the forecasted population growth, expanding economy, increasing employment opportunities, and rising household income levels suggest demand should exceed supply for the foreseeable future. Provided economic conditions do not deteriorate and/or interest rates do not increase substantially, demand for product in the submarket should remain moderate, which is further evidenced by absorption in area housing developments. Slowing absorption over the last year and pending uncertainty would suggest that absorption forecasts should be on the conservative side. The subject's proposed residential land use mix is sufficiently broad as to allow capture of a relatively wide range of household income levels. As compared to existing and planned communities in the vicinity, Heritage Hills would match favorably and competitively to said communities.

R&D LAND MARKET ANALYSIS The subject property will include R&D land area both within the LLD and within the TOD. The majority of this land area will be concentrated within the TOD with approximately 113.2 net acres. This area is located primarily north of the 5 Freeway between Alton Parkway and Bake Parkway. Additionally, there are two larger parcels located on the northern portion of the LLD along Irvine Boulevard close to the 133 Freeway. There is also a smaller parcel close to Trabuco Road. The total R&D acreage within the LLD is 68.6 net acres. The total R&D acreage within the development is 182.1 net acres. Lennar intends on selling this land area to R&D users and local developers. The discussion below gives an overview of the Orange County Flex/R&D market with additional discussion relating to the South Orange County submarket where the subject is located. Lastly, we will discuss how the subject property relates to its market area and our estimates of revenue and absorption. FLEX / R&D MARKET DATA The market data for this flex / research and development (R&D) market analysis report was attained from the CoStar Group, Inc. Flex market property subtype is defined as and not limited too R&D, office service, high technology and most specialized uses (excluding warehouse and manufacturing). Due to the wide-ranging classification of the flex property type, all market information concerning research and development property specifically are based on the data gathered from the larger spectrum of the flex property type supplied by CoStar. CURRENT TRENDS Conditions in Orange County’s flex / research and development market remained strong through the first quarter 2007 despite an increase in overall vacancy over the previous quarter. Broad-based growth in industries varying from communications to pharmaceuticals has led to a tight market with limited amount of available space. Tenants have found it difficult to find space that meets their exact needs, and many have found that they must compromise.

• The vacancy rate for the first quarter of 2007 decreased fifty basis points over the same period a year ago, from 5.5 percent in first quarter 2006 to 5.0 percent in first quarter 2007.

• Direct average rents continued to trend upward in comparison to first quarter 2006 with rents up

18.1 percent to reach $14.22 per square foot per-year, net. Despite a stabilization in vacancy over last year, the overall trend-line represents a tightening market as rents are driven upward.

• Regardless of low vacancies and increasing rents, new construction remains low due to a shortage

of space. With the specialty driven flex / research and development property unique for each tenant, the broad array of industry located in Orange County maintains strong demand for flex / R&D property.

VACANCY The flex / R&D vacancy rate in Orange County has been declining consistently since it last peaked during mid-year 2004 at 9.9 percent. By year-end 2006, the vacancy rate had dropped to 4.7 percent, and remained committed at this low rate through the first quarter of 2007.

• Orange County’s lowest vacancy rate on record occurred during fourth quarter 2006 with a 4.7 percent vacancy, although first quarter 2007 vacancy rate has risen 30 basis points over last quarter, it remains the lowest on record (last 10 years).

• Through first quarter 2007, the West County submarket posted a 1.5 percent vacancy rate, the

lowest in Orange County. Conversely, South County recorded the highest rate in Orange County’s flex / R&D market with a vacancy of 5.9 percent.

ASKING RENTS Since year-end 2002, the direct average asking rent for flex / R&D space has been rising steadily. During second quarter, 2005 rents reached $11.49 per square foot, surpassing the pervious high in first quarter 2001. Since then rents have progressed upward every quarter. As with all previous quarter direct average rents since mid-quarter 2005, first quarter 2007 posted historically high rents, this quarter recorded rents at $14.22 per square foot.

• With the first quarter vacancy rate holding stable at a low 5.0 percent, and near-term new supply limited, landlords have been able to apply aggressive increases in asking rents.

• The West County submarket is the most affordable with a direct average asking rent of $10.94

per square foot; consequently, West County has the lowest vacancy rate of 1.5 percent.

SOUTH COUNTY ABSORPTION The South County submarket (following graph) recorded a negative 88,266 square feet of absorption through first quarter 2007, the first weakening in absorption since second quarter 2004 where absorption activity registered negative 447,795 square feet. The increase in available space is credited to large blocks of space coming onto the market due to recent lease expirations. Historically, the South County submarket absorbs vacant space relatively quick, with current trends pointing toward a slight weakening in absorption and vacancy through year-end 2007. Greater absorption and decreasing vacancies are expected by year-end 2008 and the years ahead.

• South County’s strongest recorded year-end absorption was in 2000 with 932,645 square feet, and 2005 with 813,485 square feet.

• The weakest year-end absorption was recorded in 1997 with negative 152,348 square feet, and

2002 with negative 69,949 square feet.

• In comparison to the Orange County market, the South County submarket absorption cycle follows closely to that of the aggregate Orange County market.

• Steady demand for Flex/R&D space in South County will continue to drive up asking rents and

overall inventory, while absorption is expected to rebound.

CONSTRUCTION Construction activity has been quite restrained since 2002, considering the tight market conditions of the past five years. Despite the high level of demand and increased rental rates, developers have not delivered significant quantities of new flex / R&D space. Since the beginning of 2002, only 2.2 million square feet of flex / R&D space have been completed throughout Orange County.

• In addition to last quarter’s 22,269 square feet of new space in Orange County, and another 83,242 square feet completed this quarter, new projects currently under construction make up a modest 96,685 square feet.

• New construction activity has been limited due to the scarcity of available land combined with

escalating construction costs. FLEX / R&D MARKET OUTLOOK The Orange County flex / R&D market can be expected to maintain its strength in the near term, given a positive economic outlook and support from increasing international trade volumes. Low vacancy rates and the accompanying upward pressure on rental rates is expected to persist.

• The volume of leasing transactions, however, will likely subside mostly due to a lack of readily available space.

• With the supply of available land for all industrial/flex space in Orange County diminishing due

to rezoning, the viability of infill and renovation projects could heighten. HERITAGE FIELDS – R&D LAND As mentioned earlier, the total R&D acreage within the development is 182.1 net acres. Lennar intends on selling this land area to users and local developers. Based upon our conversations with Mr. Kevin Hanson, Senior Vice President, Commercial Property Group with LNR Property Corporation, the R&D land area will have an overall FAR of 32% to 35% based upon the entitlements currently in place with the City of Irvine. This equates to a total building improvement area of 1.6 million square feet for the TOD and 1 million square feet of improvements for the LLD for a total of 2.6 million square feet for the entire development. The developer has indicated that a CFD estimate of $4.00 per square foot would be an additional load on the commercial land. In our conversations with local area brokers, they indicated that the subject is well positioned to absorb the projected demand for new R&D space within the South Orange County market. The Irvine Spectrum (adjacent) and South Orange County are mostly built-out. Future R&D demand will be attracted to the subject’s central location and the proposed amenities and existing retail amenities. These brokers indicated that the subject parcels would most likely sell in the $30.00 to $40.00 per square foot range based on size and location. Additionally, they projected absorption of the subject acreage at 20 to 25 acres per year. We have considered this information for both our revenue and absorption estimates for the subject.

In estimating our absorption of the subject R&D land area, we have considered the historical overall average net absorption for Flex/R&D space for the last 10 years within South Orange County. The R&D market has a tendency to go through peaks and valleys so we also examined the overall average net absorption per year for our analysis. The South Orange County market absorbed 4,141,749 square feet between 1st quarter 1997 and 4th quarter 2006 for an overall average net absorption of 414,175 square feet per year. As mentioned previously, the South Orange County market is mostly built-out with very little land available for R&D development. Consequently, we have assumed that the subject would capture approximately 75% of the future demand for R&D space. Utilizing 75% of the South Orange County historical average absorption for R&D space equates to 310,631 square feet per year of potential R&D capture for the subject. The subject has approximately 2.6 million square feet of entitlements for future R&D development. This would equate to an absorption rate for the subject of 8.37 years. Given the subject has approximately 182.1 acres for R&D space; the average absorption would be 21.76 acres annually. These absorption projections were incorporated into the “as is” valuation (to follow). The developer 2007 Overlay Business Plan Revenue Timing shows a much quicker sell-off of the subject parcels. This plan shows initial sales in November 2007 and final lot sales in May 2011. (Please see the R&D absorption chart on the following page). The plan indicates that approximately 5.9 acres will be delivered in 2007, 41.1 acres in 2008, 75.1 acres in 2009 and 60 acres in 2010. The developer’s estimates seem aggressive given historical absorption of R&D space within the South Orange County market. Part of the explanation may lie with the fact that their revenue estimates for the R&D land appear to be below the current market. Given this pricing, it is conceivable that the land could be sold off faster but probably somewhere between their current estimates and our projections. However, we have mirrored the developer’s sequencing in our absorption schedule for the subject, delivering the acreage in the same order as the developer over the total development period. Overall, we project that the subject is well positioned to capture future R&D land demand within the South Orange County market. The residential development and retail amenities provided by the Heritage Fields master-plan should contribute to this future success. Moreover, the subject’s centralized location along both the 5 and 405 freeways should appeal to both R&D users wishing to construct an R&D facility as well as local developers looking for speculative opportunities.

AUTO CENTER LAND MARKET ANALYSIS The subject property is a proposed auto center location known as Autoland at Heritage Fields. The focus of this analysis is to discuss local demographic characteristics, retailing trends within the automobile industry; dealership profit centers; historical and forecasted automobile sales trends; and the subject's competitive position. AUTOMOBILE INDUSTRY RETAILING TRENDS Automobile dealerships have undergone considerable changes since their inception. The first dealerships were small businesses usually located in downtown areas. As cars became more affordable and dealers carried a wider selection of models, dealerships transitioned from small showrooms to larger sites that were specifically designed for auto sales and service. Dealerships also began to locate in suburban areas, to follow population growth and to secure larger, less costly sites. Two trends changed automobile retailing during the 1960s and 1970s. The first was a rapidly increasing number of imported car brands being marketed in the United States. Many of these manufacturers desired dealership locations adjacent to existing domestic dealerships in order to gain market acceptance and exposure. This led to the development of “auto rows,” in which several different dealerships were located along the same arterial, in close proximity to each other. The “auto row” was generally not a planned development. It usually contained a variety of retail/commercial uses mixed in with the automobile dealerships. The second major change was the elimination of the requirement for domestic car dealers to market only one line of vehicles. This allowed dealership owners to market several different vehicle lines, either from a single point (dealership) or several points located along an “auto row.” During the 1980s a number of communities developed planned clusters of automobile dealership sites. These planned developments became known as “Automalls.” Through 1985, there were only a handful of Automalls located in the United States, with the majority located in the west. The Automall is distinctly different from an auto row. An Automall is a planned development that is usually highly visible and accessible from major surface and freeway arterials, has no non-automotive land uses, and has an interior roadway design that allows the consumer to shop many dealers within a small area. During the mid-to-late 1980s, a considerable number of new car lines (e.g., Hyundai, Acura, Infiniti, Lexus, and Saturn) entered the market. Many of these new lines were marketed separately from other models made by the same company, which necessitated separate dealerships, and created a strong new demand for dealer locations. This trend supported the expansion of the number of dealers during the mid and late 1980s, the majority of which were in Automalls. The success of Automalls, it is believed, is due to the synergism created by the comparison opportunities presented by multiple dealerships, which outweighs the negative ramifications associated with competition. Further, most dealers agree that without the competition, it is difficult to attract the consumer, who would prefer not to travel significant distances to investigate choices. In addition, the

individual dealerships benefit from the purchasing power of the overall “Automall” in terms of advertising and promotion. Most cities desire Automalls due to the significant amount of retail sale taxes generated in comparison with the limited impact on municipal services. This has created a competition between cities to attract dealerships. Many cities offer incentives, which may include reducing the price of dealership land, attractive financing and sales tax rebates. To date, the majority of the Automalls developed within California have been located in suburban communities. The main reason for this is the lack of available “low cost” land to support an Automall in central city areas. A more recent occurrence in the marketing of new and used cars throughout the nation, similar to recent trends within the retailing industry towards large discount retailers, several new dealerships have developed around the “superstore” concept. CarMax is a used car superstore developed and then spun off by the electronics retailer Circuit City Stores, Inc. CarMax currently operates 80 used car superstores in 38 markets. CarMax also operates seven new car franchises, all of which are integrated or co-located with its used car superstores. During the twelve-month period ended February 28, 2007, the company retailed 337,021 used cars, which is 95 percent of the total 355,584 vehicles retailed during that period. Another leader in this trend is AutoNation, Inc. an automotive retailer that owns and operates approximately 331 new vehicle franchises at 257 dealership locations across 16 states. AutoNation has not had the level of success that CarMax has had in the used car sector. However they are heavily involved in new car sales and remain the largest auto group as noted below. Another trend is a shift to larger dealerships, as the number of facilities selling more than 750 new units per year has risen by almost 30 percent since 1994 while the number selling less than 150 units fell 22 percent during the same period. Dealer groups, a single private dealer owning multiple outlets, now comprise 40 percent of all dealership owners. In addition to the above referenced mega-dealers, there are several automotive groups that are public retailers operating multiple dealerships across the country. We have provided a financial summary of these top five public retailers below.

Capital Automotive Real Estate Services (formerly Capital Automotive REIT), better known as CARS is another player within the automotive industry. The real estate investment trust invests in properties used by automobile dealerships and other automobile-related businesses. The company usually buys the property of existing multi-franchised dealerships and then leases it back to the operator on a triple-net basis for 15 to 20 years. CARS own properties in nearly 33 states and Canada; most are in major cities. The properties include more than 500 automobile franchises representing some 45 major brands of automobiles. CARS was acquired in 2005 by clients of DRA Advisors for a reported $3.4 billion. The question remains as to whether the most recent trends will be successful or short-lived. Used car superstores have under-performed expectations, due mostly to today’s aggressive new car pricing, as well as a glut of used cars on the market. Buying a car “sight unseen” over the Internet or through a club store has an inherent disadvantage versus going to a dealership for a test drive. Internet activity has largely involved comparative pricing, with buyers still feeling more comfortable. Centralization of ownership is likely to be a growing trend, however. All of these trends point to the reduction in the number of stand-alone new car dealerships. Especially vulnerable are those stand-alone dealers that are functionally obsolete. Overall, the total number of automobile dealerships declined from a peak of 47,500 in 1951 to 22,400 in January 1999, 200 fewer than in January 1998. This trend is expected to continue as many major manufacturers have announced programs to limit the number of new dealerships or eliminate existing ones. The most prominent example of this is General Motors Corporation’s current $1 billion plan to eliminate 1,500 of its 8,500 dealers over the next five years. However, as with most trends, there are significant exceptions. High end, functionally designed stand-alone dealerships have begun to reappear, especially in upscale locations. These dealerships capture an exclusivity of location that cannot be achieved in an Automall setting, and upscale shoppers are not likely to shop at club stores or over the Internet. WARDS TOP 500 DEALERSHIPS In its 20th year, The Ward’s Dealer 500 is a list of top U.S. dealerships ranked by total revenues, including sales from new and used vehicles, finance and insurance and fixed-operations departments (service, parts and body shops). It's another record year in total revenue for the nation's top dealers on the Ward's Dealer 500. However, many dealers are losing money, others have gone out of business while others are barely hanging on, but the Ward's 500 members continue to sail along. Ward’s reports the total revenue for the group increased to a record $39 million. At first glance, the numbers seem to indicate the Ward's 500 had a strong year in 2006. Dig beneath the numbers, though, and troubling trends begins to emerge. The number of new units sold dropped by almost

40,000, the first time that has happened in recent memory. Similarly, used vehicle sales also went down by 16,000 vehicles. If sales continue to decrease, dealers on the Ward's 500 likely will see their overall revenue drop in the next couple of years. Decreasing sales has a cascading effect on other areas of the operation, such as service, parts and financing. Sam Pack, who has two Dallas-area Ford Motor Co.-branded dealerships (ranked 46th and 131st), admits it is a challenge offsetting the impact vehicle sales has on all of the operations. “We study the markets, we are again trying to make sure that we're taking advantage of the opportunities that exist,” he says. “We aren't focused just on vehicle sales. We're respectful of the impact of vehicle sales, but we also know we have to have the revenues of all the other departments.” Pack's Carollton store gained nearly $20 million in new-revenue, while his North Richland Hills dealership lost almost $30 million in new-car sales. Despite that, Pack says 2006 was a strong year. “It was a year in which we performed from a competitive point of view at a very high level,” he says. “We were successful in growing our business and protecting our margins. We continued to gain share of the market.” Pack's dealerships saw large jumps in parts revenue and in finance and insurance sales, while service and used-car sales provided modest gains. “We were very disciplined in our approached to the market,” Pack says. Dig into the overall revenue numbers a little deeper and there is even more cause for concern. There is an increasing difference between the haves and the have-nots, even for dealerships on the Ward's 500. For example, the top 100 dealerships on the list increased their total revenue by nearly $505 million compared with 2005 revenue. But dealers, who make up the bottom 100 of the list, may want to put away the champagne glasses. Those dealerships as a group saw $556 million less in total revenue compared with 2005. One can almost predict the brand trends. Not counting the single-point Porsche dealership on the list, Toyota Motor North America Inc. dealerships led all brands with an average store revenue increase of $6.8 million, good for $139 million per store. Of course, it helps when you have Greg Penske's Longo Toyota beefing up the numbers. The El Monte, CA, dealership continues to set new thresholds year after year in both total revenue and vehicles sold. In 2006, the world's largest dealership sold more than 27,300 new and used vehicles while generating more than $703 million in total revenue. Interestingly, two domestic brands fared well improving their average per-store revenue. General Motors Corp.'s two Buick Pontiac GMC dealerships increased their per-store revenue by $3.9 million. Meanwhile, DaimlerChrysler's eight Dodge dealerships also increased their revenue by $2.5 million. But, the 11 Chrysler-Dodge-Jeep dealerships experienced a miserable year, watching their per-store revenue plummet by $9.7 million. Cadillac dealers also had it tough losing a whopping $16.9 million in average store revenue. Not surprisingly, Ford Motor Co. dealerships also suffered as average store revenue fell $3.5 million.

So what is the bottom line for these trends? It means the ability to grow quickly is becoming the sole property of a few large dealerships or groups owning large stores. As large dealerships get bigger, their value increases, putting them out of reach of smaller and mid-sized stores. If the trend continues, it is not far-fetched to see a world in which only public dealer groups or large private investment firms have access to the type of capital that can net profitable and attractive stores. Dave Conant, who owns a large group in southern California — his Honda Superstore of Cerritos with $252 million is 18th on this year's Ward's 500 — is concerned about the trend. He questioned Irv Miller, a vice president for Toyota Motor Sales, USA Inc., during a panel in May at an American International Automobile Dealers Assn. gathering, about a Toyota dealership in Arizona that recently sold for reportedly more than $15 million. “How do you keep metro points in the hands of private dealers?” Conant asks. Miller says prices for some of their dealerships are coming down, and that Toyota would like to keep private owners in control of their dealerships as much as possible. “There will be a balance between public and private ownership of our dealerships,” Miller says. Toyota can accomplish this, and does, with strict framework agreements that dictate how many stores any one person or company can own. But over time, as private dealers find it increasingly harder to grow their portfolios; one has to wonder if the future of automotive retail will be controlled by large corporations.

DEALERSHIP BRANDING A recent phenomenon over the last decade has been the branding of dealership facilities. This is a new trend that is primarily affecting newly built dealerships. This is accomplished by the use of unique design characteristics that distinguish one facility carrying a particular car line from another. Manufacturers such as Mercedes Benz, Lexus, Nissan, Volkswagen, and GM have mandated the use of certain design features as a part of the facility. These range from minor details like use of particular color schemes on the showroom interiors to the direction of the actual construction quality of the building (i.e., Lexus which has pre-formed concrete on its showroom buildings and Mercedes-Benz that has aluminum cladding called alucabond on the exterior of its dealerships). These aesthetic and architectural features are designed to enhance the image of each of the individual brands. However, the cost of these building characteristics may not translate into value for the dealerships. In fact, in extreme cases the additional features may make the dealership less marketable to potential buyers at a later date that may want to market another line of vehicles. As such, functional obsolescence is a distinct possibility that must be considered during the appraisal process. REGIONAL AUTOMOBILE DEALERSHIP RETAIL SALES Similar to the nation overall, the onset of the recession in the late 1980s and early 1990s caused a decline in consumer spending, especially on big ticket items such as cars and homes. The overall result of the decline in sales was an oversupply of new car dealerships. The better conceived and strategically located dealerships within Automalls and established auto rows proved most resilient to the recession. Older and less functional dealerships did not survive. However, despite the recent economic recovery, level new car sales and a trend toward centralized operations indicate that there will not be a significant increase in the number of new automotive dealerships. More likely, new dealerships will be constructed within Automalls to replace one or more nearby stand-alone dealerships. It should be noted that vehicle sales are most directly related to the business operation of a dealership. Increasing or decreasing sales are typically attributable to changes in business operations rather than factors associated with the real estate. DEMOGRAPHIC CHARACTERISTICS Demographically, Southern California is considered one of the best locations in the country for automotive sales and service facilities. Southern California’s large population, high household income, and reliance on private vehicles for transportation are all desirable for the automotive industry. To assess local area demographics, we have referenced statistics within a one-, three- and five-mile radius from the subject property. These radii were selected as representing, respectively, the subject’s immediate area, primary trade area, and maximum protected trade area. The demographics statistics are provided by Claritas, Inc.

AUTOLAND AT HERITAGE FIELDSBake Parkway and 5 Freeway

Irvine, California

As shown above, the population within a one-mile radius is relatively low. This is because of the undeveloped nature of the local surroundings and the mostly office/industrial uses nearby. However, the population within a three-mile radius is relatively high. This is because of the mostly build-out nature of the larger area with lots of residential development nearby. The table demonstrates that within the three-mile radius the population has grown by 1,711 (2.33% growth) since 2000. Moreover, the population within a five-mile radius is over three times that of the three-mile radius. The average household income within a three-mile radius is below the average for the County. The population in a five-mile radius (where most potential customers are estimated to reside) is large enough to support a number of dealerships, as well. Overall, the area’s demographics are supportive of a successful new car dealership. COMPETITION/COMPETITIVE POSITION OF THE SUBJECT The subject property is located adjacent to the Irvine Auto Center within the Heritage Fields master-plan. The subject property benefits by having good exposure along the north side of the 5 Freeway and access/exposure along Bake Parkway. Presently, competition within a ten-mile radius includes 46 dealerships. To determine the supply of locally competitive new car dealers, we consulted an internet directory. It showed the following listings for new car dealers within a ten-mile radius of the subject. There are 46 automobile line-makes considered primary competition to the subject property. This is important because within the State of California a new auto dealership franchise cannot locate within 10 miles of another franchise of the same make. Vehicle Code section 3062(a)(1) gives a dealer the right to protest an additional dealership or relocation of an existing dealership of the same line-make within a ten-mile radius of the protesting dealers dealership. This statute requires that the manufacturer or distributor must first give written notice to the New Motor Vehicle Board in Sacramento and to the dealerships of the “same line-make” within the “relevant market area.”

As seen from the chart there would be very few opportunities for a buyer to establish a new franchise at this location as most of the makes are represented within a 10-mile radius from the subject. Consequently, the most likely buyer would be a dealership group within the 10-mile radius that already has an existing franchise that would like to have another point within their own trade area. In our conversations with the listing broker, Ms. Allison Schneider, with CBRE most of the potential buyers for the subject have been auto related uses such as RV, high end auto custom groups, or used vehicle sales. Aside from the above primary competition, automobile dealerships are also available in other neighboring cities. Based upon our inspection of the subject property and its surrounding environs, the subject's immediate neighborhood is recognized by local customers as a primary automobile sales and service destination.

Subject’s Marketability In comparison to the current market and competition, the subject property is considered to represent a good auto center location. The subject is directly north of the 5 Freeway and should be marketable to a number of auto related entities. (Please see proposed site plan below).

The Irvine Auto Center is located just southeast from the subject parcels. It currently contains 14 vehicle makes (The Lincoln Mercury site shown below was recently purchased by a high end used car dealership). Additionally, not included within this list are Irvine BMW and Power Toyota both located southwest of the 5 Freeway in Irvine. The center is an established auto retailing location that should appeal to other new car dealership operators that may wish to have a presence in the Irvine area but are already a part of the local trade area or from an existing dealership within the auto center looking for additional land area. The one disadvantage of the Irvine Auto Center has been its lack of adequate patron

parking area along Auto Center Drive. Consequently, other auto centers in the local area (i.e. Santa Ana, Tustin) and auto row areas within South Orange County have increased sales where the Irvine Auto Center has not seen the growth of some of these other areas. Existing dealers within the auto center could benefit from additional offsite parking area.

Based on our conversations with market participants the primary disadvantage with the subject property is the limited building area allocated to the site based on its existing zoning. Most new car dealerships require larger facilities to adequately house sales with service and parts. As seen from the list of primary dealership competition, the local area is saturated with existing auto dealerships within 10 miles of the subject. However, there are very few alternatives for auto related uses within the South Orange County area because of the built out nature of the market. The subject should absorb fairly quickly once brought to market.

Currently, there is an offer of $45.00 per square foot for the subject Parcel 5 that is located along the 5 Freeway and is 4.3 acres in size. Additionally, there is an RV dealership that has offered $40.00 per square foot for Parcel 4. At this point in time discussions are still preliminary as the subject land will not be available until mid next year. Additionally, the developer may pursue re-subdividing the site with smaller parcels as demand has been strongest for 2 acre parcels given the limitations on building area with the overall site. The developer is having ongoing discussions with the City of Irvine regarding this issue. We have taken all of this information into account with our revenue and timing assumptions for the subject.

The subject's location at the junction of the 5 and 405 Freeways is supportive of an auto center at this location. Additionally, it is located in an established auto retailing location. Overall, it is our opinion that the subject is well positioned in its marketplace and will be a viable automobile center location over the short- and long-term.

OVERVIEW OF SUBJECT EDUCATION/INSTITUTIONAL LAND USE Associated with the objectives for providing a variety of educational resources that appeal to the full spectrum of future residents of the Heritage Fields project and the larger Irvine and Orange County communities, the Great Park Plan and ultimately the project plan for Heritage Fields includes a total of 238.5 acres concentrated in the Lifelong Learning District of the Heritage Fields MPS. According to the Overlay Plan, a maximum of 1,460,000 square feet of improvements classified as educational uses may be constructed on the land parcels that are designated for institutional uses in addition to 731,300 square feet of improvements that are classified as institutional/cultural uses. The overall FAR for the maximum density permitted across institutional/cultural and educational improvements on the parcels that are designated for educational land uses is 0.21 FAR The concept of the Lifelong Learning District was addressed in the Property Description section. The intent of the district is to provide for land uses that will provide not only primary and secondary educational facilities for the new residents generated by the housing elements of the project, but more importantly, provide for uses that could support higher education such as colleges, universities, trade and technical schools as well as corporate educational and training facilities. The LLD is further expected to act as an incubator for the Research and Development Uses intended for the TODD district. According to the developer’s/owner’s 2007 business plan, all of the Educational land use parcels were expected to be sold by May 2011. We considered the terms of two written proposals we reviewed for educational land within the subject project. The first proposal is from California State University, Fullerton (January 17, 2007) discussing the acquisition of a 20-acre parcel in the Lifelong Learning District for $30 million. This equates to $34.43 per square foot of land area prior to considerations for the CFD assessment of $4.00 per square foot. However, the proposal includes one of the existing buildings (Building 829) from the former Air Base, which is currently occupied by CSUF’s Irvine campus. This proposal includes an existing facility in which California State University, Fullerton is an occupant. A second proposal was received from Lutheran High South (April 17, 2007). The letter expressed the school’s interest in purchasing approximately 35 acres in the Lifelong Learning District for $146 per square feet of FAR and requests 225,000 to 250,000 square feet of FAR. MARKETPLACE FOR EDUCATIONAL LAND The Exposition land use classification is a fairly unique land use designation that is based on one of the main “themes” underlying the Great Park plan which establishes the land uses for the subject Heritage Fields MPC. Typically, municipalities due not zone land specifically for educational or cultural purposes. In some instances, special purpose zoning classifications are established, but most often educational institutions such as private schools, trade schools, and cultural organizations acquire land through a typical market-based transaction or the land/real estate is donated to the organization. Public schools

acquire sites through both market based transactions and eminent domain as well as requiring set-asides for sites in large-scale developments such as the subject Heritage Fields project. As such, there is no truly defined, efficient marketplace for the purchase and sale of land intended specifically for educational or cultural purposes. Cultural and educational land uses are not typically income producing properties that are purchased by investors. Instead, these assets are purchased, owned and operated by the users themselves. Due to the special purpose nature of this land use, there is no readily available market data from which to develop and analysis and draw conclusions for the subject educational and cultural land use parcels. Instead, we have investigated similar uses throughout Southern California to demonstrate, in a case study format, the “market” for such land uses in the region. Our search focused on the existing public schools in the City of Irvine, the institutions of higher education found in Orange County, as well as several trade schools that are located in Orange County. PRIMARY AND SECONDARY EDUCATION The table on the following page summarizes the public schools located in the City of Irvine based on information published by the school district. Total public school enrollment totals approximately 26,630 students in 22 elementary schools, seven middle schools and five high schools. Primary and secondary education is augmented through a number of private schools. Based on information we collected in the course of our research another 700 students are served by private primary and secondary schools.

Application to the Subject Property Based on our research of public and private schools in the City of Irvine, we estimated that approximately 27,344 students are currently enrolled in primary and secondary educational institutions in the City of Irvine. Based on the most current population estimate for the City published by Claritas, Inc. primary and secondary school enrollment is equal to approximately 0.14 students per capita in the City of Irvine as illustrated in the following table. Based on the per capita ratio of students to population, we considered the “demand” for educational uses that could be generated over the next five years based on population growth estimates forecast by Claritas, and assuming that the per capita ratio would remain constant. Based on this analysis, approximately 5,101 new students will generate demand for new educational facilities in the City of Irvine over the next five years.

We applied a similar methodology for estimating possible demand for the subject’s educational land by considering the per capita ratio of students throughout Orange County. Again, based on our research, intuitions of higher education, including trade and technical schools, totals 201,259 students representing approximately 0.07 students per person in Orange County. Based on population growth estimates published by Claritas, Inc., an estimated 11,105 students will demand facilities for higher education in Orange County over the next five years.

According to the project EIR for the subject, the project entitlements are anticipated to result in a population of approximately 9,000 residents in the Heritage Fields MPC. Based on the population/student housing ratios discussed above, the population increase anticipated for the project would contribute to the demand for educational facilities to accommodate 1,893 students upon project build out. However, project-generated demand is not the only source of demand for the subject’s educational land uses, particularly for facilities of higher education. Considering the 9,000 new residents of the Heritage Fields project, the pro rata share of the overall Irvine population is approximately 4 percent of the 2011 forecast population. The subject’s 9,000 new residents also represent 0.28 percent of the forecast (2011) population of Orange County. If the subject project were to capture its pro rata share of primary/secondary and higher education students generated from forecast population growth, in addition to the 1,893 students in demand the project itself generates, an additional demand of 235 students would be created for a total demand of 2,128 students over the next five years (2007-2011). As previously referenced, the subject’s overlay plan includes a maximum development capacity of 7,800 students in 1,452,600 square feet of improvements, in addition to 731,300 square feet of institutional improvements. The letters of intent we have reviewed have indicated there exists a marketplace for educational sites within the subject development. However, the capacity of the overall project for educational and cultural land uses is significant. Based on our analysis set forth above, we estimate that the subject’s absorption period would exceed five years, and would in fact fall in the range of approximately 10 years from our date of value. We recognize that demand for the subject’s educational

land may be robust in the early phases of the development, particularly from private intuitions that are currently in the marketplace for well located, affordable sites. However, due to the somewhat limited pool of users for these sites, the typical capital structure of these organizations, their governance, and the timeframe in which they can execute a significant transaction, we have estimated an absorption timeframe that is more in line with the indications of demand suggested by population growth trends and concluded an eight year timeframe from the date of value was appropriate for the subject. We estimated the final revenue event for the educational/cultural land parcels would occur in October 2015. OFFICE MARKET ANALYSIS CURRENT CONDITIONS The Orange County office market continued to experience shifts in activity in the first quarter of 2007.

• The overall vacancy rate decreased through the first quarter of 2007 by 60 basis points to 9.1 percent, when compared to last quarter’s vacancy rate of 9.7 percent, but remains 20 basis points above first quarter 2006 vacancy rate of 8.9 percent.

• Absorption was active for the first quarter of 2007, with a positive 323,400 square feet absorbed, yet well below the 891,300 square feet absorbed in first quarter 2006.

• The overall average asking rent has increased 10.6 percent in the past year to $2.40 per square foot per month, up from first quarter 2006’s $2.17 per square foot.

MARKET CHARACTERISTICS The Orange County office market contains 74.3 million square feet of space, which ranks the market among the top 15 in the nation, on par with that of San Francisco County, Seattle-Bellevue and Central New Jersey.

• Orange County’s largest major office submarket by far is its CBD, which is comprised of 32.5 million square feet of office space. Located in proximity to the interchange of Highway 55 and Interstate 405, it includes the cities of Costa Mesa, Irvine, Newport Beach and the southern portion of Santa Ana.

• Orange County’s other sizable office markets are Central County and South County, containing 17.9 and 14.5 million square feet of space, respectively.

Office Market Statistics by SubmarketOrange County

First Quarter 2007

VACANCY Orange County’s overall vacancy rate has been on the decline since 2002. The Non-CBD market’s vacancy rate peaked during 2001 at 18.1 percent, while the CBD peaked at 19.2 percent during 2002. Since then, both markets have seen annual vacancies decline dramatically. At first quarter-end 2007, the overall vacancy rate was up 20 basis points from one year earlier, but remained tight.

ASKING RENTS The current scarcity of space, particularly for full floor availabilities in the CBD, has prompted landlords to both raise asking rents (over $3.00 per square foot per month in certain buildings) and reduce concession packages.

• The average asking rent in the CBD climbed 5.7 percent to $2.59 per square foot per month, when compared to the asking rents in the same quarter last year at $2.45 per square foot.

• In the Non-CBD markets, the average rental rate as of first quarter 2007 was $2.18 per square foot per month—10.7 percent above the first quarter 2006 rate of $1.97 per square foot.

• In the CBD, the Newport Beach submarket had the highest average asking rent at $3.12 per square foot per month, and likewise had the highest direct Class A rent of $3.14 per square foot per month.

• In the Non-CBD markets, the S.J. Cap./S. Clemente/D.P./C.B submarket in South County had the highest average asking rent at $2.68 per square foot per month. Irvine Spectrum had the highest direct Class A rent at $3.12 per square foot per month.

LEASING ACTIVITY Leasing activity was healthy for the first quarter of 2007 totaling 1.8 million square feet, yet well off the pace set in the first quarter of 2006.

• Through the first quarter of 2007, Orange County’s leasing activity totaled 953,900 and 912,900 square feet between the CBD and Non-CBD markets, respectively.

• The 1.8 million square feet of leasing activity in the first quarter 2007 has fallen below the pace set in first quarter 2006 and 2005, when activity totaled 2.4 and 3.9 million square feet, respectively.

• After the 2001 recession, the Orange County office market continued to improve, and in 2003 and

2004 recorded absorption of 2.1 and 2.0 million square feet respectively. However, since that time absorption levels have been decreasing with a yearly average of 1.1 million square feet absorbed thru year-end 2006.

• Since 2001, absorption in the CBD has averaged 0.4 million square feet annually while the Non-CBD market has averaged 0.9 million square feet annually.

Since 2002, first quarter absorption has averaged 374,610 square feet, as of first quarter 2007, absorption remains on par with the historical average posting 323,400 square feet of absorption through the quarter.

financing. In addition, the extremely high cost of new construction has many developers unwilling to undertake significant risk of long periods of vacancy after completion.

• During first quarter 2007, construction completions within Orange County totaled 101,900 square feet, 31 percent of which was delivered in the CBD.

• Office space under construction has increased sharply since last year with over 3.4 million square feet underway compared to 2.7 million square feet the same quarter last year. The limited available office space over the last few years has resulted in a surge of construction that is expected to continue through 2009.

• Future construction projects consist of a proposed 2.4 million square feet of office space throughout Orange County.

OFFICE-USING EMPLOYMENT In 2006, Orange County’s growth rate in office-using employment fell below the average for the Top 100 metro areas (Top 100) for the first time since 1999.

• Between 1996 and 2006, Orange County’s office-using employment increased at an average annual rate of 3.6 percent—far outpacing the Top 100 average of 2.0 percent.

• Between year-end 2006 and 2011, Orange County’s growth in office-using employment is forecast to slow to an average of 1.7 percent per year—just below the Top 100’s projected growth rate of 1.9 percent.

• Orange County’s office-using employment is concentrated in the center of the county north of the split of Interstates 5 and 405. The market areas with relatively high shares of office employment include the Greater Airport Area, from Irvine to Fountain Valley; South County near Lake Forest and Laguna Hills; and Central County, near the cities of Orange, Santa Ana, Tustin and Garden Grove.

OFFICE MARKET OUTLOOK Over the course of this year, the Orange County office leasing market is expected to experience its current path by tightening further. Office vacancies are anticipated to remain in the single digits along with a steady rise in rents.

• Orange County’s construction pipeline remains modest relative to expected demand; new product coming online is expected to exhibit asking rental rates in excess of $40.00 per square foot annually.

• With vacancy rates holding steady and 3.4 million square feet of new office space coming online during 2007 and 2008, construction is expected to slow over the next five years until enough space is absorbed to warrant any new large scale development.

• The office market in Orange County is expected to continue to thrive due to a diversity of industries within the market and a highly skilled labor pool.

• As Orange County remains a desirable location for office operations, including corporate headquarters, the long-term outlook for the office market is quite positive.

RETAIL MARKET & TRADE AREA ANALYSIS TRADE AREA OVERVIEW A retail center’s trade area contains people who are likely to patronize that particular retail center. These customers are drawn by a given class of goods and services from a particular tenant mix. A center’s fundamental drawing power comes from the strength of the major tenants as well as the regional and local tenants which complement and support the anchors. A successful combination of these elements creates a destination for customers seeking a variety of goods and services while enjoying the comfort and convenience of an integrated shopping environment. In order to define and analyze the subject’s market potential, it is important to first establish the boundaries of the trade area from which the subject retail center may draw its customers. In some cases, defining the trade area may be complicated by the existence of other retail facilities on main thoroughfares within the trade areas that are not clearly defined or whose trade areas overlap with that of the subject. We have made certain reasonable assumptions of the extent of the boundaries of the primary and secondary trade areas this area based upon physical, demographic, and geographic data available. MARKET OVERVIEW The Orange County Metro Statistical Area (MSA) retail market is a diverse compilation of strip and convenience centers, neighborhood, community, and regional shopping centers, and other retail property types. Neighborhood centers are the smallest type of shopping center, generally with a gross leaseable area of less than 100,000 square feet. Typical anchors include supermarkets, pharmacies and personal services. Community centers consist of 100,000 to 300,000 square feet and usually contain one junior department store, a variety store or discount department store, a supermarket and specialty stores. The Orange County MSA is comprised of five submarkets. The following charts illustrate the layout of the Orange County MSA submarkets and the retail data for each of the submarkets segregated by anchored and non-anchored centers. The subject property is located in the Central submarket of the greater Orange County retail market.

edged up to 3.1%. Vacancy remains extremely low in the MSA as the vacancy rate has been below 5.0% since 1997, and historically in our data range, vacancy remains on the low of the spectrum. Vacancy for both the neighborhood and community centers in the MSA is expected to increase over the next five years, exceeding to 4.5% by 2011, according to the Reis forecast. Forecasted absorption is expected to trail new completions, however it will not do so by a significant amount, and vacancy will increase in the foreseeable future.

Source: REIS 1Q07 CONSTRUCTION According to REIS, neighborhood and community center development has been steady in Orange County within the last five years. The 405,000 square feet completed in 2006 was the largest addition to the inventory since 2002, although in the 1990s, annual completion volumes in excess of one million square feet were common. The 2000 to 2006 period saw an annual average of just 276,143 square feet completed and vacancy continued to fall. With just 57,000 square feet of neighborhood and community center space under construction at first quarter 2007, a much larger completion volume of 575,000 square feet is forecast through the end of the year. Beginning in 2007, however, supply is forecast to take a slight lead over demand, with an average just over one-half million square feet per year during the 2007 to 2010 forecast period. Below is a chart of projects for the MSA as of first quarter 2007.

Effective rents have also historically consistently increased with the greatest growth in 1998 at 6.5%. The lowest effective rent increase was in 1996 when growth was reported at 2.5% over the prior year.

rents, like asking rents, have been fluctuating. The greatest growth in effective rent was in 2006 when effective rents increased 6.9%. The last two years effective rents have increased significantly, rising 5.9% in 2004 and 2004. The first quarter 2007 data demonstrates continued growth in both asking and effective rental rate trends at 1.5 and 1.0%, respectively.

NEIGHBORHOOD AND COMMUNITY CENTERS - DATA CONCLUSION The tight 37.3 million square foot Orange County neighborhood and community center sector remains tight which exerts upward pressure on rents. The Orange County market not only has low single digit vacancy, with an average of less than 2% vacancy of anchor spaces in many submarkets, but also has the consistency of rent gains from year to year and even quarter to quarter. The area had the upper tier on rent gain of the top markets tracked by Reis in first quarter 2007 and some of the lowest vacancy rates, although new development remains limited throughout the Orange County MSA. CONCLUSION We have analyzed the retail trade history and profile of the subject's region and primary trade area in order to make reasonable assumptions as to the continued performance of the property. A metropolitan and locational overview was presented which highlighted important points about the study area. Demographic and economic data specific to the trade area were also presented. The data is useful in giving quantitative dimensions of the total trade area, while our comments serve to provide qualitative insight into this market. A compilation of this data provides the basis for our projections and forecasts particular to the subject property. The following summarizes our key conclusions. The Orange County retail real estate market has shown healthy rental growth and solid occupancy. For the neighborhood and community center segment of the market, Reis reports a first quarter 2007 vacancy rate of 3.1%, up 10 basis points from the prior quarter, and up 120 basis points from year-end 2005, which had a vacancy rate of 1.9%, the lowest on record in the MSA. Reis reports that rent increased by an average of about 1.6% in each of the four quarters of 2006, with the fourth quarter featuring respective gains of 1.4% in both asking and effective rents. With few exceptions, the average asking rent has risen by between 0.7% and 2.0% in every quarter since early 2002. The year 2007 will mark a shift in the supply-demand dynamic for neighborhood and community center space, at least to a small extent. During the 2000 to 2004 period, net absorption averaged 400,000 square feet per year, somewhat more than the increase in supply. During 2006 the negative 15,000 square feet of net absorption fell far short of the increase in supply, and increasing overall vacancy slightly. Beginning in 2007, however, supply is forecast to continue its slight lead over demand, with the former averaging over 532,000 square feet per year and the latter 497,000 square feet per year during the 2007 to 2011 forecast period. Despite its recent weakness, the Orange County economy remains one of the nation’s largest. Its diverse economy includes major industries such as service-producing, aerospace, defense, high-tech manufacturing, electronics and government which help buffer losses in any one sector. APPLICATION TO THE SUBJECT PROPERTY We have considered the macro level market trends as well as the subject’s submarket performance relative to the greater Orange County retail market. We have weighed the market trend against the

planned retail component of the subject Heritage Fields project and have reached the following conclusions. The subject Heritage Fields project is entitled for 225,000 square feet of retail development. This represents 0.60% of the total Orange County retail inventory and 2.66% of the subject’s Central submarket’s current inventory. The subject’s retail land area per the overlay plan totals 40.5 acres in the LLD and the TODD. The overall retail density for the subject’s retail component is 0.127:1 FAR. According to information compiled by REIS, a total of 1,883,000 square feet of new retail space is currently under construction in the Orange County market. Another 2,231,900 square feet is planned or proposed. However, only 242,000 square feet of the 2,231,900 square feet of planned/proposed retail space is located in Irvine. These figures are not inclusive of the subject’s 225,000 square feet. The owner/developer’s business plan contemplates delivery of the subject’s retail space as follows:

Parcel Use C&W Value/SF Total Value

Lennar Est. Absorption

C&W Est. Absorption Acres

L17 Retail $30.00 $25,613,280 Sep-09 Sep-09 19.6 L20 Retail $35.00 $14,026,320 Oct-09 Oct-09 9.2 L21 Retail $35.00 $6,403,320 Jun-08 Jun-08 4.2 T1c Retail $35.00 $9,100,000 Feb-10 Feb-10 6.0 T12e Retail $40.00 $2,696,960 Dec-07 Jun-08 1.5

Given the strength of the Orange County retail market, and in consideration of the limited supply anticipated for the subject’s Irvine area, it is our opinion that the developer’s contemplated timing for delivery of the subject’s retail component (superpads) is reasonable. We have therefore estimated absorption of the subject’s retail component consistent with the timing set forth in the developer’s 2007 adopted business plan with one minor exception. The ownership/developer estimates a December 2007 absorption for a small 1.5-acre parcel within the TODD. To the best of our knowledge, as of the date of the appraisal, there were no offers or letters of intent for this parcel. The timing of delivery/sale seems aggressive based on the current status of the project and the lack of a contract in place as of the date of the appraisal. We therefore extended the developer’s forecast absorption by six months for this parcel, which we have estimated will be absorbed in June 2008. OVERVIEW OF ORANGE COUNTY AGRICULTURE Historically, agriculture was one of the dominant industries in Orange County. Much of the land was in agricultural production dominated by citrus and fruit production. Over the course of the last century, agricultural land uses gave way to more profitable enterprises as the Orange County area developed. Agricultural uses are still found throughout Orange County; however, large scale production has greatly

diminished. In fact, in many instances, agriculture is viewed as an “interim” as opposed to a primary land use. The subject Heritage Fields project features 177.4 acres within the Lifelong Learning District that have been dedicated for agricultural uses. Due to the nature of the project, and the history of the entitlements, for the purposes of our analysis we have considered the agricultural uses as permanent uses within the context of the project. Although agriculture is not a high-profile industry in Orange County, the Farm Bureau estimates that it contributes more than $300 million to the local economy. When all economic factors are considered, including payroll, purchase of goods and transportation, agriculture has a total value to the local economy of $1 billion. In compliance with the California Food and Agricultural Code Section 2279, the Agricultural Commissioner compiles Orange County agricultural production information. We reviewed a copy of the 2005 Crop Report prepared by the Orange County Agricultural Commission, which we have summarized below. The report is based on basic crop and plant production data collected from many sources including grower surveys, regulatory and inspection data, shipment data, and industry assessments. The total gross value of Orange County agricultural products for the year 2005 (most current report available) was $312,336,287 representing a 6% increase compared to the 2004 overall income. Agricultural production values are based upon the “free on board” packed price at the first point of delivery, and include cost of production, harvesting, and preparation for market. Gross values, therefore, do not reflect net returns to the producer. Federal incentive, conservation and other support payments are excluded from this report. The following are highlights of the 2005 Orange County Crop Report:

1. Strawberry value decreased by 15% with a reduction in acreage. 2. Nursery stock value increased by 14% to $240,609,723. 3. Avocado value decreased by 22% due to a decrease in production. 4. Vegetable production, acreage and value decreased.

Strawberry value decreased by 15% with a reduction in acreage. Avocado value was down 22% in 2005 due to a decrease in production.

Apiary income showed an increase of $3,291 in 2005. Orange County apiary owners reported an

increase of 3% in the total value of apiary products.

Nursery stock and cut flowers continue to rank first in Orange County agricultural production. Gross returns increased by $29,171,063 from the previous year. The total nursery stock and cut flower income was $240,609,723. Shipments of nursery stock to other states continued to help this industry.

The total value of livestock production was increased by $125,363. This was 41% more than the

income for 2004. This was in part due to the favorable weather conditions allowing a longer time for the cattle to graze in Orange County. The total income from livestock was $430,933.

The total value for the vegetable crops was $16,599,448. This is a decrease of 9% from 2004.

Key crops include green beans, cabbage and peppers.

Total field crop value increased by $31,119. This increased the overall value of the field crops by 3%.

The California Department of Conservation tracks agricultural land use throughout the various counties in California. According to their most recent report (2004), the amount of agricultural land continued to decrease in Southern California overall, and in Orange County in particular due to increased urbanization. Since a 1998-2000 study, nearly 6,800 acres of farmland and grazing land have been removed from agricultural categories in Los Angeles, Ventura and Orange counties, while 5,339 acres were added to the urban total. Since the 1990 survey, more than 130,000 acres have been removed from agricultural uses in the five-county Southern California area while urbanization claimed more than 144,000 acres. Over the 1990-

2002 period, new urbanization in the greater Los Angeles area was equivalent to the size of all 16 Orange County cities from the Los Angeles County line south to Costa Mesa and east to Anaheim/Yorba Linda. Annually, this equates to new urban land acreage larger than the city of Thousand Oaks. In Orange County, 4,609 acres of new urban land were developed on a mixture of irrigated farmland and non-agricultural land. Urbanization accounted for almost all the net decrease of 3,348 acres in agricultural categories. Since 1990, Orange County gained just over 25,000 urban acres as it lost 9,400 farmland acres. Orange County cities reported that 9,920 acres have been committed to non-agricultural uses due to the approval of subdivision maps, the sale of bonds for infrastructure, or other permanent commitments. The agricultural land in these Southern California and in Orange County specifically will continue to face development pressure in the foreseeable future. Public subsidies and financial assistance programs are in place to encourage continued agricultural uses in urbanizing areas. Land use “dedications” such as the designation in Heritage Fields are an example. Through the Department of Conservation, the state offers programs that provide financial incentives to keep land in agricultural use. The California Farmland Conservancy Program makes grants available to local governments, land trusts or resource conservation districts to purchase permanent agricultural conservation easements from willing landowners. These easements prohibit future development. Farmland Security Zone and Williamson Act contracts provide potential tax breaks to landowners who commit to keeping their land in agricultural use for periods of 20 or 10 years, respectively. Enrollment in the Williamson Act – a voluntary program that gives landowners potential property tax breaks in exchange for a 10-year commitment to maintain agricultural or open-space uses – dropped by 33 percent between 1991 and 2002 in the five-county Southern California area. Removing land from a Williamson Act contract is often a precursor to development. According to the California Department of Food and Agriculture, Ventura County remained in the top 10 counties for gross agricultural value at more than $1.16 billion in 2002, while Riverside County was in the number 11 position at $1.06 billion. San Bernardino, Orange and Los Angeles counties had a combined 2002 production value of $1.25 billion.

available fore agriculture, the economics of agriculture in the county suggest that there is growth in the industry (6 percent between 2004 and 2005). The value of agricultural land that can be put to a “higher and better use” often outweighs the economic returns that can be generated from agricultural production. However, the agricultural data suggest that agriculture is a viable land use, particularly considering the subsidies that are available. In contrast to much of the A-zoned land in Orange County, the subject’s agricultural parcels do not possess an alternative use. Therefore, due to the nature of the project entitlements, the highest and best use of these parcels is for agricultural production. The subject’s 177.4 acres represents less than 1/10th of one percent (0.70) percent of the 25,133 total “bearing” agricultural acres in Orange County according to the 2005 Crop Report. This increase in inventory is very minimal, and given the overall increase in the value of production, it is our opinion that the subject’s agricultural land will be absorbed at the rate forecast by the subject ownership/developer as outlined in their adopted 2007 business plan.

OVERVIEW OF SUBJECT EXPOSITION LAND USE Associated with the objectives for providing a variety of recreational and open space uses, the Great Park Plan and ultimately the project plan for Heritage Fields includes a 215.7-acre land parcel that is designated “Exposition” land use. This parcel, identified as L27, is located in the Lifelong Learning District. According to the Overlay Plan, a maximum of 708,000 square feet of improvements may be constructed on the Exposition parcel. The permitted uses are referred to in the project EIR as “commercial recreational” uses. Commercial recreational uses may include performance and concert venues, fairgrounds, convention and exposition centers, demonstration shows, training venues and a variety of other recreation and learning activities. We were not provided with a description of the developer’s/owner’s specific plans for the Exposition parcel, if any such plans are available. To the best of our knowledge, there are no letters of interest or contracts in place for this parcel as of the date of value. According to the developer’s/owner’s 2007 business plan, the Exposition parcel was intended for disposition in September 2011. MARKETPLACE FOR EXPOSITION LAND The Exposition land use classification is a highly specialized designation that is somewhat unique to the Heritage Fields plan. Due to the special purpose nature of this land use, there is no readily available market data from which to develop and analysis and draw conclusions for the subject parcel. Instead, we have investigated similar uses throughout Southern California to demonstrate, in a case study format, the

Convention Centers Anaheim Convention Center The Anaheim Convention Center is the largest convention center on the west coast with a total 1.4 million square feet. Space is categorized and allocated within three major categories: 815,000 square feet of exhibition space, 200,000 square feet of pre-function space, and 130,000 square feet of ballroom and meeting space. The convention center was completed in 1967 and has since undergone three substantial expansions. The project is adjacent to the Disneyland Resort, a recreational resort complex with three hotels, two theme parks, and a shopping, dining, and entertainment area. The Disneyland hotel, the oldest of the three, was opened in 1955 and provides 990 rooms in three high-rise towers as well as unparalleled conference facilities. Disney’s Grand Californian Hotel and Paradise Pier Hotel offer 745 rooms and 489 rooms, respectively. Los Angeles Convention Center The Los Angeles Convention Center is located in Downtown Los Angeles and hosts 350 annual events such as the Greater Los Angeles Auto Show. Its events attract 2.5 million visitors annually, generate secondary client spending in excess of $1 billion, and generates 12,000 hospitality and service sector jobs. The center was opened in 1971 with over 210,000 square feet of exhibition space and went through major expansion projects in 1993 and 1997. Currently the center offers 720,000 square feet of exhibition space, 147,000 square feet of meeting rooms with a 299 seat presentation theater, and on site parking for 5,600 vehicles. The center has suffered due to the lack of convention hotel rooms in proximity to the center. Currently under construction is a convention center hotel with both Ritz-Carlton and J.W. Marriott flags that is intended to bolster the ability of Los Angeles to attract convention business. The hotel project has been heavily subsidized by the City of Los Angeles. San Diego Convention Center The San Diego Convention Center is situated in the Marina District of Downtown San Diego and, per 2005 statistics, hosts 224 events annually. For the same 2005 period, these events generated $1.2 billion in regional economic impact and $25.5 million in hotel room and sales tax revenues. The facility opened in November 1989 and currently features 615,701 square feet of exhibition space, 204,114 square feet of meeting space, and 284,494 square feet of pre-function, lobby, and registration areas. The convention center is within walking distance of 90 restaurants, 35 nightclubs, and 100 retail shops. There are an estimated 7,500 first-class hotel rooms within a mile of the convention center, which is located approximately 10 minutes from the airport. PERFORMANCE VENUES Orange County Performing Arts Center The Orange County Performing Arts Center, located in Costa Mesa, is home to the Pacific Symphony Orchestra, Opera Pacific, the Philharmonic Society of Orange County, and the Pacific Chorale. The center officially opened in 1986 and today has several theaters of various sizes and a 46,000 square feet community plaza. The largest of the theaters are Segerstrom Hall, an opera style house with 3,000 seats and the Renee and Segerstrom Concert Hall with 2,000 seats. The two smaller theaters, Samueli Theater and Founders Hall, seat 500 and 250, respectively.

Copley Symphony Hall The Copley Symphony Hall in San Diego was constructed in 1929 as the 68,000 square feet luxury movie theater, Fox Theater. The hall has a seating capacity of 2,252 and is home to the San Diego Symphony. Dorothy Chandler Pavilion The Dorothy Chandler Pavilion in downtown Los Angeles, opened December 1964, seats 3,197 people and is home to the Los Angeles Opera and Music Center Dance. Application to the Subject Property While the Exposition land use nomenclature pre-supposes convention or exposition type uses, our research indicates that a successful convention or exposition-type venue that draws regional and national convention business demands hotel accommodations in close proximity to the venue. Our research into similar uses, convention or exposition uses in particular, suggests that typically, quasi-governmental agencies or authorities are established to construct and operate convention or exposition-type facilities in major markets. Los Angeles and San Diego, for example, both have quasi-governmental authorities that developed the convention centers in these cities. The Heritage Fields plan does not include specific plans for hotel uses, which would limit the appeal of such a facility for this type of business. Furthermore, as of the date of value, there are no plans for the formation of an operating entity that would develop and operate such a venue at the subject property. A possible use for the subject’s designated Exposition property could be an event area that would host live music performances or other public arts and entertainment events. As demonstrated by the discussion above, there are many facilities like these in Southern California. Due to the costs of construction, high operating costs, and the scarcity of land and corresponding land prices, such venues are generally not economically viable without government subsidy, corporate ownership/sponsorship or private contributions. The developer’s 2007 adopted business plan estimates a revenue event/sale of the subject’s 215.7-acre Exposition parcel will occur in September 2011, or approximately 4.5 years from our date of value. As demonstrated anecdotally in the discussion above, significant public venues such as that contemplated for the subject (708,000 square feet is approved) are delivered to the Southern California region on a sporadic basis that can be measured in decades. The complexity of these developments, the scale of the construction projects themselves, and the magnitude of the investment require a structured arrangement, typically involving public and private entities as well as large donors and/or corporate sponsorships to come to fruition. To the best of our knowledge, such a structure is not currently in place nor contemplated for the subject’s Exposition parcel. We assume that such an entity, if formed, would not have the capability to purchase a site for a project prior to having a structure and some degree of financing commitments in place.

As the subject’s Exposition land is also categorized as “recreational” it is conceivable that a professional or semi-professional sports area would be suitable for the property from a land use perspective. Locations for sports teams are a highly complex matter involving multiple layers of government stakeholders as well as the team franchises themselves. Investigation of this particular use for the subject is beyond the scope of our expertise and this assignment; however, we note that the size of the subject’s Exposition parcel and the magnitude of the approvals (708,000) would likely be suitable for such a venue. For these reasons, and in consideration of the most recent examples in Southern California, we have estimated that it will require approximately five years to structure and begin implementation of a strategy for the development of a commercial recreation facility on the subject’s Exposition parcel. We have, therefore, extended the owner's/developer’s timeframe by one year to September 2012. This extension also considers the status of the implementation of the balance of the Heritage Fields project as of 2012. The improvements to the infrastructure, the completion of the vertical construction of the earlier phases, and the critical mass resulting from new residents and businesses will add to the viability of a community serving commercial recreational use at this location.

HIGHEST AND BEST USE COMMENTARY The appraisers must properly develop highest and best use conclusions of a property from two perspectives: 1) as if vacant, and 2) as if improved as proposed. Highest and best use can be defined as:

1. Highest & Best Use - The reasonably probable and legal use of vacant land or an improved property, which is physically possible, appropriately supported, financially feasible, and that results in the highest value. The four criteria the highest and best use must meet are legal permissibility, physical possibility, financial feasibility and maximum profitability. 2. Highest & Best Use As Vacant - Among all reasonable, alternative uses, the use that yields the highest present land value, after payments are made for labor, capital, and coordination. The use of a property based on the assumption that the parcel of land is vacant or can be made vacant by demolishing any improvements. 3. Highest & Best Use As Improved - The use that should be made of a property as it exists. An existing property should be renovated or retained as is so long as it continues to contribute to the total market value of the property, or until the return from a new improvement would more than offset the cost of demolishing the existing building and constructing a new one. 9

HIGHEST AND BEST USE AS VACANT LEGAL PERMISSIBILITY The subject is the Phase I portion of the 4-phase development of the Legacy Park Master-plan, the vital central portion of the MCAS Tustin Specific Plan. This specific plan stems from the MCAS Tustin Reuse Plan which was adopted October 31, 1996 and amended on September 8, 1998. The Final Joint Environmental Impact Statement/Environmental Impact Report (FEIS/EIR) was adopted by the Tustin City Council on January 16, 2001. The MCAS Tustin Specific Plan was adopted by City Council Ordinance No. 1257 on February 3, 2003. Subsequently, Tustin Legacy Community Partners, LLC, and the city of Tustin proposed modifications to the MCAS Tustin Specific Plan which entailed a proposed zone change, MCAS Tustin Specific Plan Amendment 05-002. The zone change 05-002 was approved by the Tustin City Council on April 3, 2006 per Resolution No. 06-43. MCAS Tustin Specific Plan Amendment was adopted on April 17, 2006 with the Tustin Legacy Disposition and Development Agreement (Master Development) approved by the Tustin City Council on May 4, 2006. Permitted uses and development standards shall be in accordance with the MCAS Tustin Specific Plan/Reuse Plan.

The property includes approved Tentative Tract Map 17026 provided by the developer with a copy located in the Addenda. Notable is that the tentative map approval is pending the developer meeting typical conditions of approval by the city of Tustin. This is typical of master-planned communities in the area and not anticipated to unduly hinder the subject’s development as proposed. It is recommended that the client have available a copy of the Tentative Map(s) Conditions of Approval and retain appropriate legal council to review said document to assess the impact of the Conditions in their lending decisions.

PHYSICALLY POSSIBLE The topography of the subject property is flat terrain. Proposed road improvements and utility connections are in place, adjoin the subject's perimeter, or will be available via extensions from existing mains. Geotechnical investigations indicate that development of the subject is physically possible, provided the conclusions and recommendations of the study are incorporated into planning and construction. Per extensive studies, there are no soils, hazardous waste, geotechnical, biological, environmental, archeological, or paleontological conditions that would preclude development as proposed. Residential development is common in the area and the site was not reported to vary substantially in site characteristics from other improved properties. Thus, to the best knowledge of the appraisers, the legally permitted land uses were physically possible.

FINANCIALLY FEASIBLE The ongoing sales activity for master-plans and entitled land throughout Southern California and Orange County would indicate that an element of profit exists between costs of development and final sale revenues, providing acquisition of land at market prices and development at anticipated construction costs.

As demonstrated in the market value “as is” section, the discounted cash flow indicated a total property value of negative $5,899,945. Of note is that the Phase I “as is” value reflects the heavy burden of extensive backbone and local infrastructure costs that will not only benefit the subject’s Phase I portion but the remaining 3 phases. While the costs are incurred up front, the additional value of future phases are not included in the “as is” value of Phase I. Therefore, the subject land, Phase 1 of Legacy Park Master-plan, as a stand alone entity based on the current allocation of costs and projected revenues has no supportable value.

Under the 20% IRR assumption, the implied static profit was $44,310,928, or 13.45% of land sale revenues. Said profit would equate to 15.54% of the total costs including the indicated negative land basis. Note that this analysis was nonleveraged. Thus, the actual return on equity, or cash-on-cash, would be higher if the investment was financed. However, given the negative land value basis, financing would have to consider future revenues to some extent to support the potential of value within the subject land. Assuming all costs of development were financed, and a developer could secure a land acquisition loan of some magnitude, the cash-on-cash return could be 40%±. Per a survey of active market participants involved in the acquisition and development of similar properties, these rates of return would be adequate to attract investment into a development project such as Legacy Park Master-plan (Phase I). Note that the profit indicators are for master land development only and do not reflect any additional profit from construction of product in the individual planning areas. MAXIMALLY PROFITABLE Based on the previous discussion, the Legacy Park Master-plan (Phase I) project as proposed via the Area Plan and Tentative Tract Map was considered to be a market acceptable plan, and would bring the highest return to the land in obtainable revenues (with consideration for the entire master-plan), and is the maximally profitable use of the subject site as vacant. Finally, as previously discussed in this report, the subject’s submarket is being developed with new master-planned projects. Considering the current and proposed infrastructure and the trend in development of vacant land in this area, a residential project is appropriate and conforming to the area and is the Highest and Best Use of the site as vacant. HIGHEST AND BEST USE AS IMPROVED OR AS PROPOSED The proposed land use, per the current and/or pending entitlements, was also found to meet the criteria of Highest and Best Use (see “as vacant” discussion). MOST PROBABLE BUYER The most probable buyer of the subject property, “as is,” “as proposed,” or “as improved,” would require a buyer that could support a large equity investment. The most probable buyer profile for a project such as the subject would include larger regional and national developers and/or builders, which often joint venture with various equity partners.

MARKET VALUE “AT COMPLETION” - PLANNING AREAS / PARCELS This initial analysis involved estimating the market value of specific planning areas/parcels within the Heritage Fields Master-plan. The development and/or sales comparison approaches were utilized in estimating the market value for each planning area/parcel. Four of the superpad parcels include affordable low income housing and ethic and faculty housing (L10, L24, T8 and T10a) totaling 734 units. Typical of master-plan communities and affordable housing requirements, each parcel or portion is essentially a “cost” of development and are not revenue generating from land sale proceeds. These parcels would likely be transferred to an affordable housing developer. The following assumptions were deemed reasonable for the analyses and valuation of the larger project as a whole and reflect the currently intended build-out proposal on the part of the developer. DEVELOPMENT METHOD (RESIDENTIAL LAND) The development method is used by developers to determine the price they can afford to pay for land assuming certain costs, gross sales, and return considerations. This approach "backs out" a value for the land, taking into account anticipated sales revenues of the proposed homes, costs of construction, absorption projections, lending criteria, and return expectations. Basically, it is the inverse of the cost approach, which results in a residual to land value indication. In this case, the appraisers developed “generic” build-out models for each respective planning area/parcel by minimum lot and/or product type. Note that the planning areas/parcel designations are consistent with the developer’s pro forma. Thus, 24 residential residual models were formulated, reflecting the 24 various product proposals where a development method analysis was applicable. Individual planning area development approach assumptions, development and sales schedules, static models, and yield (discounted cash flow) models can be found in the Addenda. The following information summarizes the content and conclusions of the comprehensive analyses.

PLANNING AREA MARKET VALUATIONHeritage Fields Master Plan, Irvine, California

Approach To Value

STATIC ANALYSES In the static method, total costs, expenses, and profit were deducted from the total aggregate of retail revenues on a straight line basis, indicating a residual to land value. The planning areas, including detached lots, attached residential units, mixed-use product, and commercial uses were analyzed assuming a “superpad” condition, which is a common method of delivering these types of sites to builders in this submarket. Base Pricing As exhibited in the following table with consideration for only those planning areas and parcels to be analyzed with the development method, the appraisers assumed average weighted base pricing from $538,000 to $2,797,000 and $374 to $511 per square foot, depending on product. Further discussion on base pricing assumptions can be found in the Market Analysis. Please refer to the market analysis for additional detail on the product line designations and pricing.

HYPOTHETICAL PRODUCT BASE PRICING BY PRODUCT TYPE(1)

Heritage Fields Master Plan, Irvine, California

Lot Premiums / Options In addition to base pricing, the appraisers also included retail lot premiums for the various delineated planning areas (groups). In allocating lot premiums, consideration was given primarily to view potential, lot sizes, negative locational features, and in-project location characteristics. The developer estimated 1.0% to 5.0% of the proposed base pricing for lot premiums on average for both detached and attached product lines. The appraisers surveyed current projects within the subject submarket as detailed in the following table. Lot premiums ranged upward to $250,000 with a premium to base ratio ranging from 0.0% to 6.85% with an average of 2.19%. The majority of similar projects to the subject with flat terrain and similar locations were typically on the low end of the range at 0% to 2% per unit on average. Of the attached projects surveyed, premium estimates ranged from $0 to $50,000 for luxury attached product. For attached product, the majority of premium estimates indicated an average unit premium range of about 1% to 5% of base pricing. In all likelihood, the subject’s attached product would also have limited to moderate premium opportunities given the flat terrain and lack of significant views. However, premium

LOT PREMIUM SURVEYHeritage Fields Master Plan, Irvine, California

Based on the foregoing, the appraisers estimated the average lot premium potential for each planning area. Also taken into consideration was the intended product for each planning area. Lot premium potential tends to increase companion to an increase in product size and pricing, and vice-versa. For the most part, the proposed land use plan should result in minimal to average premium potential for the majority of the planning areas/parcels. Select oversized lots with adjacent open space would result in the highest lot premiums. The flat topography should minimize area view potential. Further, the proposed street plan should result in favorable in-project lot characteristics such as cul-de-sacs, low traffic patterns, etc. and a minimization of negative impacts. However, pending completion of grading, it was difficult to adequately quantify lot premium or discount potential resulting from views, lot size, negative factors, etc.

Based on the survey and the subject’s flat terrain, lack of significant views, and smaller lot sizes, the appraisers estimated base detached residential lot premiums of 1% of the base price. Premiums of 2% were estimated for detached product with good locations, but average view potential. The highest premiums of 5% were estimated for detached product with golf course and park adjacent locations, larger lot sizes, low densities and above average view potential. The appraisers estimated base unit premiums of 1.0% to 1.5% of the base price for the attached product. For the luxury attached product, a premium of 5.0% was estimated. The previous survey of similar developments indicated that premium revenues of 1.0% to 5.0% of base pricing are common in Orange County. The subject’s premium potential is minimal to moderate due to the overall size of the project and the large number of product lines offering no or minimal view potential. However, the few product lines that do offer view potential (golf course and park locations) will command significant premiums. Thus, the estimated lot premium revenues were supported and fairly conservative compared with many new developments in the submarket.

source as a separate item, and was not included in the base pricing. Typical option revenue percentages for option upgrades in the subject’s market have averaged 5% to 10% over the last few years with upper-priced homes usually at the higher end of the range and vice versa due to the general affordability and buyer profile at each end of the spectrum. With the housing market downturn over the last year or so, average option revenues at the lower end of the range are more reasonable. Considering the foregoing, average net options revenues of 3% of the base price for each planning area/parcel, or $4,000 to $19,000 per unit, depending on planning area/parcel, were considered reasonable at this preliminary stage of development.

Developers typically anticipate a 60% to 100% recovery of permanent model upgrades (i.e. floor coverings, wall coverings, appliances, landscaping, etc.). Commonly, marketable model upgrades are approximately 50% of the total model home budget. For example, assuming a $200,000 average model home budget, 50%, or $100,000, would be “marketable” permanent upgrades. Of this, a 60% to 100% recovery is expected, or $60,000 to $100,000. A review of model home sales indicated typical model premiums ranging from $50,000 to $200,000, depending upon home size. The appraisers allocated model unit premiums from $59,000± to $280,000±, depending on the assumed model upgrade budget (discussion to follow), as shown next.

Summary of Aggregate Retail Revenues As exhibited in the following table, average home pricing (including base pricing, lot and model premiums, and options) ranged from $564,299 to $3,042,275 and $390 to $535 per square foot, depending on product. The overall average is $1,119,011, or $437 per square foot. This is generally inline with the previous base pricing indications of $255 to $657 per square foot for detached product and $312 to $634 for attached product for those comparables most similar to the subject in location and product. As would be expected due to lot premiums, model premiums, and options, the price per square foot is toward

the middle of the overall base price range of $255 to $657. Further discussion on product pricing assumptions can be found in the Market Analysis section of the report. Predevelopment Costs A cost of 0.5% of revenues was estimated for predevelopment, architecture and acquisition costs. After a market comparison and review of the developer’s pro forma, this cost was considered to be reasonable for the subject. Backbone Infrastructure / Mass Grading / Majors Reimbursements The subject planning areas (detached lots, commercial and attached units) were assumed to be in superpad condition with all offsites installed, rough grading having occurred, and master development in-place. Accordingly, major backbone infrastructure, master development, common area costs, and companion reimbursements were not included in the planning area valuation but were recognized in the forthcoming “as is” valuation for the entire property.

Hard Construction Costs The appraisers reviewed several cost breakdowns from other residential subdivisions appraised throughout Orange County. These cost breakdowns reflected direct hard construction costs from approximately $75 to $150 per square foot for detached residential product and $100 to $150 per square foot for attached residential product, varying primarily with quality, product size, and subdivision location.

(1) Directs do not include individual lot landscaping, fencing, or indirects. Per the developer, direct costs (excluding option upgrade costs) were estimated at $77 to $107 per square foot for the detached residential product and $83 to $124 per square foot for the attached residential product. For the most part, all other variables being the same, smaller product generally costs more to build on a per square foot basis than larger product due to economies of scale. Typically, however, the higher costs generally associated with more amenitized larger product will more than offset the economies of scale. Based on the subject's assumed product lines and pricing in comparison to other cost breakdowns, and per information from other market participants, the appraisers reconciled direct construction costs of $77 to $124 per square foot. These estimated direct costs were inline with the local

market indications. Note that direct costs do not include onsite indirects (supervision, general conditions, temporary utilities, etc.), nor individual lot landscape and fencing. Indirect Construction Costs Indirect construction costs, including such items as onsite water, utilities, temporary power, general labor, supervision, etc., were estimated on a cost per square foot of livable area basis. The appraisers reviewed indirect construction costs from similar projects in Southern California. The market survey indicated that costs from similar projects ranged from $3.00 to $8.00 per square foot, varying primarily with project size, development duration, and subdivision location. For the subject planning areas, indirect costs were estimated at $4.00 per square foot, which was reasonable and consistent with indirect costs experienced in other projects in the area. Intract Land Development / Development Impact Fees The subject planning areas were assumed to be in a superpad condition with all offsites installed and master development in-place. Builders (buyers) of the lots would be responsible for final intract land development and development impact fees at permit. Per the budget provided by the developer, intract land development costs range from $11,000 to $161,765 per lot, depending on planning area/parcel. It should be noted that the developer’s intracts are on the high end of the range of $15,000 to $60,000 per unit typically seen by the appraisers. The developer indicated that their estimates were in line with other Orange County projects and may be high due to increasing costs over the last two years. With this in consideration, intract costs were deemed to be slightly high but reasonable given the range of lot sizes. Fees at permit, exclusive of building permit/plan check fees, ranged from $4,844 to $21,518 per lot depending upon planning area/parcel, and averaged $10,900 per lot. Note that the fees at permit figures do not include building permit and plan check fees, which were included as an additional construction cost category. The appraisers relied upon the estimates provided in the developer’s cost analysis, which were assumed to be reasonably true and correct.

BUILDERS' INTRACTS & FEES BY PRODUCT TYPEHeritage Fields Master Plan, Irvine, California

Landscape / Fencing (Individual Lots) Product pricing was assumed to reflect standard side/rear-yard fencing and front yard landscaping. Non-house construction costs vary substantially between projects depending on landscape requirements, fencing, offsite requirements, etc. Allowances of $3,000 to $10,000 per lot are common in similar subdivisions. Based on a review of subdivision cost budgets, an allowance of $5,000 to $10,000 per non-model production lot, depending on planning area and lot size, was deemed reasonable for side/rear-yard wood or wrought iron view fencing, front yard landscaping, and/or other site improvements. For the subject, the attached product was estimated to have minimal, if any, non-house construction costs and no costs were allocated. Any costs that would be incurred are assumed to be included in the developer’s direct costs. The costs were deemed reasonable given the early development stage.

NON-HOUSE CONSTRUCTION COSTS BY PRODUCT TYPE(1)

Heritage Fields Master Plan, Irvine, California

Building Permit / Plan Check Fees Building permit/plan check fees were estimated at $1.50 per square foot. Said cost was based on a review of building permit/plan check fees from comparable subdivisions in the Orange County area. Master Developer Profit Participation In addition to the purchase price of each residential planning area/parcel, merchant builders shall pay to the master developer 70% of all net profit (above 7% and 8%) realized from the construction of homes (after allowable deductions for merchant builder development costs, land purchase price, and a profit allowance). Based on the information provided by the developer, the appraisers utilized a 7% profit deduction on all detached product planning areas and an 8% profit deduction on all attached product planning areas. The net profit would be calculated and paid semi-annually.

General and Administrative Costs Management fees include typical G&A such as offsite management, administration, and overhead. The costs are generally projected as either a percentage of sales and/or a monthly allowance. A market survey indicated management fees typically range from 3.0% to 5.0% but most often 3.0%, which was used in the development method analyses.

Marketing and Sales A marketing and sales budget category includes all advertising, marketing, brochures, publications, commissions, closing costs, warranties, escrow fees, and miscellaneous legal fees. A market survey indicated sales costs from similar projects were typically 3.0% to 5.0% and marketing/advertising costs ranged from 2.0% to 3.0%, depending on product, price range, joint marketing programs, etc. In this case, considering the price of the product and development/sales term, marketing costs were estimated at 2.0% of revenues. The marketing expense figure was assumed to be inclusive of a master marketing fee paid to the master developer, which contributes to the community advertising program coordinated by the master developer. Sales/closing costs of 3.00% were incorporated into the analyses.

Model Complex Budgets Model budgets typically include the cost for decorating, sales office, upgrades, furnishings, site improvements, and customer parking. Renovation costs would be required for the removal of the sales office, front perimeter fencing, and the parking lot. Based on a review of other model budgets, and per conversations with several builders, model home decorating/upgrade/merchandising budgets of $133,333 to $700,000 per model, depending on product, were incorporated into the production lot build-out assumptions. An additional $2,500 to $5,000 per model home conversion allowance was included in the month prior to delivery of the models dependent upon product type.

MODEL HOME COSTS BY PRODUCT TYPE(1)

Heritage Fields Master Plan, Irvine, California

Homeowners’ Fees The developer would be required to pay association fees on unsold standing inventory in phased construction. Due to the early development stage, the developer has not formulated the Heritage Fields Master-plan community-wide association fees. Therefore, the appraisers surveyed similar master-plans within the subject’s submarket. Homeowner association (HOA) fees range from $110 to $323 per unit per month for comparative detached residential projects and from $290 to $401 per unit per month for comparative attached residential projects within the subject’s submarket. With the comparables, the study in

consideration, and the costs reported by the developer, HOA fees of $115 per unit per month for the detached product and $315 per unit per month for the attached product were incorporated into all of the planning area/parcel cost budgets. Base Property Taxes and Special Assessments The developer is required to pay normal property taxes and any other assessments over the course of development. Property taxes assumed an initial purchase at the indicated value from this approach, a 1.75% overall tax rate, 2.00% annual escalations (maximum allowed by law), and a diminishing inventory. Financing / Holding Costs A typical subdivision development package usually consists of construction financing for the full hard and related soft costs at rates of .25% to 1.00% over prime with accelerated repayments based on 110% to 120% of the prorated loan per unit. As of the date of value, the prime rate was 8.25%. Interest rates were recently near historically low levels and are anticipated to be increasing over the short- and long-term. Accordingly, holding costs for the production lots were based on a total loan-to-value ratio of 75%, 110% release price, and 9.00% interest rate. Construction and land development were financed up to a maximum loan-to-aggregate retail value ratio of 75%. A land loan (draw) was included, provided total construction costs resulted in a loan-to-value ratio not exceeding the maximum. Monthly interest payments were made throughout the sell-out period until the note was paid off. Loan points and fees, or the equivalent facility fee, of 1.25% were included. Miscellaneous A miscellaneous allowance of 1.00% of sales was included for costs and contingencies not accounted for in the other cost categories. The allowance is allocated monthly over the course of development. Profit In a static analysis, a typical developer/builder will evaluate profit by deducting all construction and sell-off costs from the projected selling price of the completed units. The remaining figure represents the developer's lump sum profit figure. The developer then relates this figure back to the projected selling price, or a construction cost figure, to determine the percentage return. The ratio provides a unit of measure to judge the adequacy of the venture's profit in relation to the developer's perceived risk. The appraisers surveyed consultants, builders, and developers regarding required profit for this type of investment. Overall, a consensus was that a static analysis profit rate ranging from 7% to 12% of sales was reasonable on detached residential construction, typically at the lower end of the range. Most participants in tract housing, primarily represented by larger national builders, are anticipating 8% to 10% in static profit in this submarket. Given the site is “infill” in nature, builders would be acquiring superpads, and the competition amongst national builders for “vertical” only construction and sales programs, an 8% static profit was deemed reasonable for detached residential lot development. Attached residential development static profit rates are typically higher than standard detached production housing, normally ranging from about 10% to

15%. We have utilized a 10% profit factor for the attached residential The appraisers’ profit rates consider development by national, regional, and local builders which are represented by the overall ranges previously mentioned. SUMMARY OF STATIC ANALYSES The indicated residual land values via the static model are exhibited in the following table. For the development method, the market value for the detached product as totally finished lots with fees was estimated by summing fees at permit with the residual land value indicated from the development method. On those planning areas/parcels with attached product, no costs to finish were applicable. Summation of the land residual finished lot figures with the costs to finish indicated finished lot/superpad values ranging from $222,166 to $1,452,531 per lot, depending on the planning area/parcel. Note that the implied superpad values include fees due at permit for detached product while the attached product superpad values do not include intracts or fees due at permit.

YIELD ANALYSES The yield analysis was accomplished by applying a discounted cash flow technique. Anticipated sale revenues, loan criteria, profit, costs, expenses, etc., were projected over the total development period and periodic net cash flows were discounted on an annual basis at an appropriate discount (return) rate.

sum of the discounted cash flows resulted in a present value, or residual to land value. Assumptions were similar to those in the static analysis. The only cost variances were in property taxes and financing, which reflected a land basis per this model. The other major difference would be utilization of the discount rate (IRR) as opposed to static profit rate. Timing and Absorption The Development and Sales Schedules for the respective product types, included in the Addenda, provide an overview of the absorption and development assumptions for each product type. For the subject detached and attached product, the first month in the cash flows correlates to the acquisition date of the lots and planning areas/parcels in a superpad condition. Intract/offsite development was assumed in Month 1 for both attached and detached product. Model construction was scheduled for Month 4. Start of production unit construction was in Month 6 and initial release was scheduled for Month 5. Initial delivery would be in Month 11. Subsequent construction cycles for both attached and detached product were scheduled at five-month intervals. The appraisers were provided a Market Analysis and Product Program Study for the Heritage Fields Master-planned Community completed by The Concord Group dated April 10, 2007. The appraisers analyzed the subject and the competition and concurred with the absorption rates presented in the Concord Study. The product absorption rates are presented in the following table.

PRODUCT ABSORPTION RATES BY PRODUCT TYPE(1)

Heritage Fields Master Plan, Irvine, CaliforniaMonthly Absorption

Sustained absorption reflects the sales period from initial product release to the date the product sells out. Effective absorption reflects the actual number of months from initial release to final close of escrow and delivery to the individual buyer(s). Overall, absorption was scheduled at a sustained rate of 2.00 to 6.00 homes per project per month, depending on product type. Detached product has sustained monthly absorptions between 2.00 and 5.50 home sales per month, with effective absorptions ranging from 1.95 to 4.44 home sales per month. Attached product has sustained monthly absorptions ranging from 4.00 to 6.00 sales per month. Effective monthly absorptions for attached product range from 3.27 to 4.86 homes per month. Typically, final absorption rates obtained from builders include the closing period. Thus, the effective absorption rates offer an additional comparison indicator. Revenue and Expense Escalation Considering the scheduled development, sales, and build-out duration, neither revenue nor expense trending was incorporated into the cash flow. Reconciled static profit and discount rates (IRR) reflected the “static” assumptions for home revenues and costs.

Entrepreneurial Reward / Discount Rate Developer's profit and discount rate assumptions are interrelated. Profit can be included as a line item expense in the cash flow or reflected in the discount rate. There are several ways to handle entrepreneurial profit in a cash flow forecast. The two most common in this market are 1) deduction as a line item expense based on a percentage of retail sales revenues under a static residual model and 2) increase the discount rate to account for the entrepreneur’s contribution in addition to project risk under a yield residual model. As merchant developers in this market typically recognize profit and return requirements in yields to equity under a yield analysis, this method was used. Since there is no deduction for profit, the bottom line cash flow must be discounted to account for the overall required return to the property. Under these assumptions, the sum of the net cash flows, discounted appropriately, results in the amount a developer/builder could pay for the land, while realizing given profit, equity yield, and financial criteria. Yield rates for subdivision development are not generally published. Several consultants, builders, developers, and other investors were surveyed regarding yield requirements for this type of investment. Overall, a consensus was that equity internal rates of return were greatly dependent on the term of the investment. Due to costs and delays in acquiring alternative developments, short-term projects often have equity yield rates well above 40% whereas longer-term projects typically required internal rates of returns from just below 20% to over 30%. Iterating to the static method resulted in leveraged IRRs ranging from 32.16% to 52.05%. The higher IRR indications for the attached product are not unusual given the shorter build-out periods on the town home product where revenues are not obtained till the last half of the cash flow. With consideration for the above along with the projected development durations for the subject product types, the leveraged discount rates were deemed appropriate. Said rates reflect the non-trending assumption discussed above. The following table summarizes the yield residual land values and leveraged internal rates of return per product type.

SALES COMPARISON APPROACH (RESIDENTIAL – ATTACHED AND DETACHED PRODUCT) The appraisers have analyzed the residential planning areas based on the 24 product types. In our analysis, we chose a representative planning area population for each product type. In a later section of this report, we will extrapolate our product type analysis to all residential planning areas. The residential portion of the Heritage Fields project consists of 16 detached products and 8 attached products. In the sales comparison approach we have analyzed both attached and detached land sales based on a finished lot price (detached) or superpad price (attached). Quantitative adjustments, if appropriate, were applied for property rights conveyed, terms of sale, conditions of sale, market conditions, overall tax rate, and physical characteristics. Specific adjustments were not deemed to be absolute, but were the appraisers’ attempt to account for the value contributions of the various factors in the marketplace. This analysis involved a comparison of sales, pending sales, listings, etc., to the subject’s planning areas/parcels. The appraisers gathered extensive land sale transaction data from Orange County and more specifically, the Central submarket and similar submarkets. More than 10 multi-family and 20 single

family land transactions, listings, and/or contracts were researched and confirmed. Multi-family sales ranged from about $182,953 to over $695,000 per unit based on superpad condition. With regard to single family product, more recent finished lot prices were in the general range of $270,000 to $3,000,000, depending on specific lot size, location, etc.

ATTACHED RESIDENTIAL PRODUCT TYPES Heritage Fields includes eight attached product types. These product types are identified as Products 1, 2, 3, 9, 26, 27, 28 and 51. The following is a summary of the product types analyzed:

• Product 1 is mid-rise flats (136 units analyzed); • Product 2 is row townhouse (101 units analyzed); • Product 3 is luxury triplex (100 units analyzed); • Product 9 is luxury attached (85 units analyzed); • Product 26 is garden flats/town homes (85 units analyzed); • Product 27 is brownstone villas (112 units analyzed), • Product 28 is townhomes (112 units analyzed); • Product 51 is attached product (112 units analyzed).

A search was made for attached residential land sales in the Orange County area. Overall, eight sales were deemed relevant and specifically analyzed herein. The eight sales were analyzed on a superpad price per unit basis, which is typical for attached residential land in this market. The attached product types for Heritage Fields vary from 5.5 to 25.0 dwelling units per acre (DU/acre). For the purposes of this analysis we have grouped the attached land sales by density, specifically: low, medium and high density. The low density analysis addresses Products 3 and 9 (densities ranging from 5.5 to 6.0 DU/acre), the medium density analysis addresses Products 2, 26, 27, 28 and 51 (13.0 to 18.0 DU/acre), and the high density analysis addresses Product 1 (25.0 DU/acre). The attached land sales adjustment grids (by the three groupings) follow the discussion of the sales and the adjustment process.

City of San Juan Capistrano approximately 14.0± miles southeast of the subject. The density is 8.0 dwelling units per acre. The property was entitled with a tentative map in place and was in superpad condition at the time of sale. The seller was Suncal Companies and the buyer was Centex Homes. The site is planned for development with 58 attached homes. As mentioned, for the purposes of this analysis we have grouped the attached land sales by low, medium and high density. The low density analysis addresses Products 3 and 9 (densities ranging from 5.5 to 6.0 DU/acre) will be identified as Group 1. The medium density analysis addresses Products 2, 26, 27, 28 and 51 (13.0 to 18.0 DU/acre) will be identified as Group 2. The high density analysis addresses Product 1 (25.0 DU/acre) will be referred to as Group 3. Property Rights Conveyed No adjustments were warranted for property rights conveyed as all of the land data sold with fee simple property rights. Financing (Terms of Sale) None of the sales was reported to include atypical financing warranting adjustments. Conditions of Sale Sales conditions include any distress influences, less than arm’s length transactions, improvements on the site contributing to value, and other related influences that were not attributable to financing, market conditions, or physical differences. None of the sales required adjustments for condition of sale. Market Conditions (Time of Sale) The sales used in the adjustment grid analysis occurred between October 2003 and February 2006. As previously discussed, residential land prices incurred appreciation in the Orange County submarket over the 2003, 2004, and 2005 periods with a softening occurring in 2006 and 2007 due to decreasing demand. Based upon an internal comparison of the data, and an examination of current or pending prices for similar lots in the submarket, upward adjustments were warranted for the earlier sales. Overall, we applied upward adjustments for sales that occurred in 2004 of 10% and downward adjustments of 10% for sales in 2005 and 2006.

General Location / Specific Location / Overall Tax Rate The economic, political, and social influences in a community, as well as the specific orientation of a site within a neighborhood, require consideration for possible location adjustment. All of the data were from the Orange submarket, and deemed similar in general location. Location takes into consideration the comparables’ and the subject’s physical orientation to the surrounding area, including proximity to local services and the quality and appeal of the community at large. Heritage Fields, will be a “trophy” master-planned community and will include several significant amenities such as the Great Park, golf courses, club houses, various trails, and a main street retail component. Most of the comparables used in this analysis have inferior specific location compared to the subject property. The comparables located in Tustin and Anaheim (Land Sales 2, 3, and 7) were adjusted upward 13%± to 15%±. The comparable located in Stanton was adjusted upward 35%±. The comparable located in Orange (Land Sale 5) was adjusted upward 25%±. The comparables located in Irvine (Land Sales 1 and 6) were adjusted upward 10%±. The comparables located in San Juan Capistrano (Land Sale 8) were adjusted downward 15%±. San Juan Capistrano is a superior location to the subject property due to its coastal proximity and southern Orange County location with proximity to San Diego County. This category also addresses the subject’s and the comparables’ overall tax rates. Buyers are often unwilling to pay a similar price for a home in an area having a high tax rate (resulting from CFDs or Mello Roos fees) as in an area with a low tax rate due to the additional monthly payments involved. Consequently, merchant builders typically pay lower prices for the land in high tax rate areas. As all of the comparables have similar overall tax rates as the subject (1.70%± to 2.00±) no adjustments were required in this analysis. Premium Potential The premium potential for the subject property varies with location in the master-plan. The primary premium potential for the subject property’s attached product would be associated with limited views and elevations. Overall, the subject’s attached product indicated average premium potential. All the comparables had similar premium potential and no adjustment was made for this element of comparison. Economy of Scale It would seem reasonable that in comparison to smaller-sized developments, larger-sized projects would typically sell for a slightly lower price per unit since the builder would have more extensive carrying costs. The inverse would be expected for smaller projects. Another consideration influencing this adjustment is that builders require a project of sufficient size to amortize many of the fixed costs of doing business, as well as to provide the homebuyer with ample selection. That minimum project size depends upon the particular demands and financial ability of the individual builder. The subject product types, for the attached product, vary from 85 to 136 units. The analyzed land comparables ranged from 38 to 255 lots. Note that although a smaller project would have lower overall carrying costs, it would also have higher costs in amortization of marketing expenses, models, etc. Further, some builders are willing to pay a premium to have a larger number of lots in a single location rather than a similar number of lots dispersed in several locations. Demand for residential land has also resulted in minimal, if any, economy

of scale discounts for larger lot count projects. In the current market, there is no measurable difference for the project sizes bracketing the subject. Density All other factors being similar, parcels with a higher density tend to have a lower price per unit, though the overall price of the land is higher. It has been our experience that only significant differences in density fall into this category. This may be due to differences in product which can offset density or possibly developers in Orange County do not differentiate most small to moderate differences in density due to the high demand for attached land in Orange County. The subject lots were divided into three categories. The low density analysis addresses Products 3 and 9 (densities ranging from 5.5 to 6.0 DU/acre) will be identified as Group 1. The medium density analysis addresses Products 2, 26, 27, 28 and 51 (13.0 to 18.0 DU/acre) will be identified as Group 2. The high density analysis addresses Product 1 (25.0 DU/acre) will be referred to as Group 3. In Group 1 the subject densities vary from 5.5 to 6.0 DU/acre. The comparables used in this analysis varied in densities from 8.0 to 13.0 DU/acre. Upward adjustments were applied to Land Sales 3 and 6 of $12,000 per unit, or 4%± to 7%± of adjusted sales price per unit. Upward adjustments of $5,000 were applied to Land Sales 7 and 8, or approximately 1%± of the adjusted sales price per unit. In Group 2 the subject densities vary from 13.0 to 18.0 DU/acre. The comparables used in this analysis varied in densities from 15.2 to 17.1 DU/acre. No adjustments were applied. In Group 3 the subject density is 25.0 DU/acre. The comparables used in this analysis varied in densities from 12.1 to 17.1 DU/acre. Downward adjustments were applied to Land Sales 1 through 4 of $15,000 per unit, or between 5%± and 8%± of adjusted sales price per unit. Proposed Product The proposed product size of the subject and comparables was also considered. For the most part, variances in proposed product are companion to the lot size adjustment. For this analysis, the proposed product of the comparables was considered similar to the subject. Entitlements It is often expected that due to risk, costs, and additional carry, lower prices would be paid for projects in the earlier stages of development (i.e., un-entitled land) than for projects closer to completion (i.e., Final Map). The subject planning areas were assumed to be in superpad condition, with tentative map approval. All of the comparable sales had tentative map approval at the time of sale and/or delivery of the lots/units to the buyer. As all the comparables have similar entitlements compared to the subject property no adjustments were applied.

Profit Participation The subject property will be subject to a Profit Participation Agreement between the master developer (Lennar) and the prospective home builder. In addition to the purchase price of each residential planning area/parcel, merchant builders shall pay to the master developer 70% of all net profit realized from the construction of homes. The net profit shall be paid at the time of home sales. Essentially, merchant builders are obligated to acquire the land on terms where they pay the master developer 70% of net profits for distribution, after all costs (including 8% for profit). Based on the results of the development method residual analysis, various profit participation requirements resulted for the various product types. Calculation of this cost to the builder results in the following: Group 1 – a downward adjustment of 10.8%; for Group 2 – a downward 10.3% adjustment, and for Group 3 – a downward adjustment of 11.3% of the adjusted sales price per unit for those comparables that are not subject to a profit participation agreement. Entitlement Risk Due to added carrying costs and exposure risk from extended project life, it is expected that lower prices are paid for projects in earlier stages of development (i.e., unentitled land) than for projects closer to completion (i.e., final map). The risk associated with entitlements also varies upon specific market conditions at the time of sale. Entitled land in appreciating markets with strong demand would have a lower perceived risk than similar land in stabilizing or depreciating markets with little demand. It is expected that higher prices are paid for projects with lower entitlement risk relative to demand. As previously discussed, the subject is assumed to have a tentative map in place and all the comparables are entitled with tentative maps. Therefore, no adjustments were necessary for this element of comparison. Stage of Development For similar reasons to those stated above (carry costs and exposure risk from an extended project life), it is expected that lower prices are paid for projects in earlier stages of development (i.e., raw land) than for projects closer to completion (i.e., blue top and finished site). The subject is assumed to be in superpad condition. Comparables in superpad condition were considered similar to the subject property and no adjustment was warranted. Land Sale 4 is in raw condition and an upward adjustment of $10,000 or approximately 5%± of the adjusted sales price per unit was applied to this comparable. RECONCILIATION – ATTACHED RESIDENTIAL PRODUCT TYPES As previously mentioned, the subject product types were split into three groups represented by three adjustment grids. Group 1 (Products 3 and 9) applies to the subject’s lower density product between 5.5 to 6.0 DU/acre. For this group, before adjustments the sales prices for Comparables 3, 6, 7, and 8 ranged from $203,355 to $695,000 per unit, with an average of $395,702 per unit. After having applied relevant quantitative adjustments to the comparable data, the adjusted prices narrowed to $199,020 to $536,500 per unit, with an average of $358,021. All of the sales were taken into consideration and the analysis of the comparable data would suggest that a per unit value of $340,000 would be reasonable for Products 3 and 9 via the sales comparison approach.

Group 2 (Products 2, 26, 27, 28 and 51) applies to the subject’s medium density products between 13.0 to 18.0 DU/acre. For this group, before adjustments the sales prices for Comparables 1, 2, 4, and 5 ranged from $182,953 to $308,461 per unit, with an average of $230,608 per unit. After having applied relevant quantitative adjustments to the comparable data, the adjusted price range narrowed to $188,658 to $290,615 per unit, with an average of $241,664. Most reliance was placed on Comparables 1, 2, and 4 and the analysis of the comparable data would suggest that a per unit value of $260,000 would be reasonable for Products 2, 26, 27 and 28 via the sales comparison approach. We have concluded of $265,000 for Product 51 due to its slightly larger proposed product. Group 3 (Product 1) applies to subject’s high density product at 25.0 DU/acre. For this group, before adjustments the sales prices for Comparables 1, 2, 3, and 4 ranged from $217,337 to $308,461 per unit, with an average of $235,708 per unit. After having applied relevant quantitative adjustments to the comparable data, the adjusted prices ranged narrowed to $221,071 to $273,615 per unit, with an average of $212,004. Most reliance was placed on Comparables 1, 2 and 4 and the analysis of the comparable data would suggest that a per unit value of $205,000 would be reasonable for Product 1 via the sales comparison approach. The value conclusions also reflected an internal comparison between the subject’s various product types, utilizing similar adjustments as in the adjustment grids. The adjustment grids are located on the following pages. A summary of the estimated values, for attached product, is as follows:

There has been considerable land sales activity for production home lots in the Orange County area. The most recent sales, or pending sales from the Central submarket and comparable submarkets were deemed to be the best available and most appropriate for comparison to the subject’s production lot product types. A search was made for detached residential land sales in the Orange County area. Overall, nineteen sales were deemed relevant and specifically analyzed herein. Of these, the majority were incorporated into individual adjustment grids representing the various minimum lot size classes of the subject’s product. Specifically, the detached land sales were grouped, by size, into five adjustment grids for analysis. The

Quantitative adjustments, if appropriate, were applied for property rights conveyed, terms of sale, conditions of sale, market conditions, overall tax rate, and physical characteristics. Specific adjustments were not deemed to be absolute, but were the appraisers’ attempt to account for the value contributions of the various factors in the marketplace.

Sale 18 (Crystal Cove – Nautilus III) represents the June 2005 sale of 20 lots located at the Nautilus III area of Crystal Cove in Newport Beach, approximately 6.5 miles southwest of the subject. The reported finished price was $2,000,000 per lot for 12,000 minimum square foot lots. The lots were to be delivered in a finished condition with Final Map. The preliminary home sizes and pricing were estimated at 3,182 to 4,102 square feet and from $3,200,000 to $4,600,000. Lot premiums are significantly above average due to ocean views. Sale 19 (Crystal Cove – Seacrest) represents the July 2005 sale of 29 lots located in the Seacrest community of Crystal Cove, approximately 6.5± miles southwest of the subject. The reported finished price was $3,000,000 per lot for 21,000 minimum square foot lots. The lots were to be delivered in a finished condition with Final Map. The preliminary home sizes and pricing were estimated at 6,519 to 7,678 square feet and from $5,800,000 to $7,900,000. Lot premiums are significantly above average due to ocean views. As mentioned, for the purposes of this analysis we have grouped the detached land sales by lot size. Specifically, the detached land sales were grouped, by size, into five adjustment grids for analysis. The minimum lot sizes examined included (1) Group 1 - 2,400 to 3,300 square feet; (2) Group 2 - 4,424 to 5,000 square feet; (3) Group 3 - 6,000 to 7,000 square feet; (4) Group 4 - 8,250 to 10,200 square feet; and (5) Group 5 - 12,000 to 18,000 square feet. COMPARISON / ADJUSTMENT PROCESS Property Rights Conveyed No adjustments were warranted for property rights conveyed as all of the land data sold with fee simple property rights. Conditions of Sale Sales conditions include any distress influences, less than arm's length transactions, improvements on the site contributing to value, and other related influences that were not attributable to financing, market conditions, or physical differences. No conditions of sale were found to exist with the comparables. Financing (Terms of Sale) Anything less than a cash equivalent basis sale might require adjustment for financing considerations. This includes below or above market interest rates, atypical payback period, buy-downs, and exchange influences. None of the sales were reported to include atypical financing warranting adjustments. Market Conditions (Time of Sale) The sales occurred between January 2004 and February 2006. As previously discussed, residential land prices incurred appreciation in the Orange County submarket over the 2003, 2004, and 2005 periods with a softening occurring in 2006 due to decreasing demand. Based upon an internal comparison of the data, and an examination of current or pending prices for similar lots in the submarket, upward adjustments were warranted for the earlier sales. According to Hanley Wood data, detached home price points (price per square foot) decreased an average of 0.06% monthly from the 3-year period starting 2nd quarter 2004

to the 1st quarter 2007. Monthly price decreased 0.33% monthly for 2004 (9 months data), increased 0.48% monthly for 2005, and decreased 0.02% monthly for 2006. In the first quarter of 2007 the average price per square foot was $367, a decrease of 6.85% from the prior quarter. During the same 3-year period, the average home size increased about 8.71%. Overall, we applied downward adjustments of 10% for sales in 2005 (including January 2006), and no adjustments for sales in 2006 and 2007.

Overall Tax Rate The subject’s overall tax rate is estimated to be 1.75% by the developer. The sales overall tax rates range from 1.01% to 1.20%. Variances in tax rates are interrelated with locational factors and location adjustments, if applied. Often times the negative impact of higher tax rates is offset by superior locational amenities and infrastructure. Further, those projects within a CFD and having higher tax rates continue to find strong demand as most product is being sold while under construction.

The adjustment applied to the comparables initially isolates the difference between the comparable tax rate and the subject tax rate. That tax differential is applied to the average home price of the products in the lot size class. The present worth of the annual tax differential was calculated, and further discounted at 40% to identify a land adjustment. The adjustments ranged from -$90,000 to -$25,000 depending on the tax rate and the estimated home price. General Location The economic, political, and social influences in a community, as well as the specific orientation of a site within a neighborhood, require consideration for possible location adjustment. All of the data were from Orange County submarkets, and deemed similar in general location. Specific Location Location takes into consideration the comparables’ and the subject’s physical orientation to the surrounding area, including proximity to local services and the quality and appeal of the community at large. Heritage Fields will be a “trophy” master-planned community and will include several significant amenities such as the Great Park, golf courses, club houses, various trails, and a main street retail component. The comparable located in Santa Ana was adjusted upward 15%± (Land Sale 3); in Orange upward 25%± (Land Sale 9); in Irvine upward 10%± (Land Sales 1, 10 and 12); and in Yorba Linda upward 5%± (Land Sale 4). The locations of Santa Ana, Orange, Irvine, and Yorba Linda are considered inferior to the subject location and amenity level. Comparables located in San Juan Capistrano were adjusted downward 15%± (Land Sales 7, 8 and 13); in Newport Beach downward 25%± (Land Sale 14); and in San Clemente downward 10%± (Land Sales 16 and 17). Newport Beach, San Juan Capistrano and San Clemente (Talega) are superior locations to the subject property due to their coastal proximity and/or southern Orange County location with proximity to San Diego County.

V A L U A T I O N S E R V I C E S 2 2 4

Premium Potential As the retail prices of future home sales are upwardly influenced by lot sizes over the minimum and view potential, these factors are important value influences for subdivision land. At this stage of development, it appears that the subject product types will have average to good premium potential. Each sale was rated for lot premium potential in comparison to the subject product types. Land Sales 7, 8 and 13 are located in the Pacifica San Juan community in San Juan Capistrano, and have minor elevations and views. For the subject product types that have good view potential (Groups 3 to 5) upward adjustments of $25,000 to $70,000 were applied to these comparables. Land Sales 16 and 17, located in the community of Talega in the City of San Clemente also have minor elevations and views. These comparables were adjusted upward between $50,000 and $70,000 for Groups 4 and 5. Land Sale 14 is located in the Crystal Cove community of Newport Beach. Sale 14 has superior elevations and views and downward adjustments of $50,000 to $70,000 were applied to this comparable. Land Sale 12 is located in Irvine and has fairly level topography with premium potential primarily attributable to lot size. An upward adjustment of $35,000 was applied to this comparable. Economy of Scale/Project Size The economy of scale adjustment assumes that in purchasing decisions a potential buyer of subdivision land would consider the carrying costs and risks associated with the development term of a project. It would seem reasonable that in comparison to smaller-sized developments, larger-sized projects would typically sell for a slightly lower price per lot since the developer would have more extensive carrying costs. The converse would be expected for smaller projects. Another consideration influencing this adjustment is that developers require a project of sufficient size to amortize many of the fixed costs of doing business, as well as to provide the home buyer with ample selection. The minimum project size depends upon the particular demands and financial ability of the individual developer. However, with the demand for entitled, ready-to-develop residential land at strong levels, a project size adjustment is nominal, if at all. The comparables involved purchases of 20 to 113 lots, compared to 39 to 100 lot populations examined at the product level for Heritage Fields. Thus, no adjustments were warranted for economy of scale. Minimum Lot Size Lot size adjustments and project density were also considered. Although “minimum” lot sizes are the typical standard for comparison, lot width and depth considerations are critical (when available) in analyzing and comparing lot sizes. In addition to adjusting for differences in minimum lot size, width, depth, and/or density, the appraisers considered the housing (size) proposed for construction on the respective sites. This rationale is reasonable in that in planned communities the master developer and merchant builder usually agree upon the product size as a condition of the sale, which often affects the ultimate price per lot. The master developer and merchant builder agree on the product size to reduce direct competition among active projects in the same community. Considering the above, the appraisers applied adjustments to several of the comparables as follows: Group 1: -$15,000 to -$10,000 (Land Sales 3, 9, and 10); Group 2: -$25,000 (Land Sale 8); Group 3: +$10,000 to +$20,000 (Land Sale 7 and 8); Group 4: -$50,000 (Land Sales 14 and 16), Group 5: +$50,000 to +$150,000 (Land Sales 13, 14, 16, and 17). Larger adjustments were required for Group 5 as the comparables used in this adjustment grid

analysis range varied from 8,400 to 12,500 square feet, whereas, the subject lot sizes range from 12,000 to 18,000 square feet. Proposed Product The proposed product size of the subject and comparables was also considered. For the most part (Groups 1 to 3), variances in proposed product size and pricing are companion to the lot size adjustment. In Group 4, the subject proposed product ranges from 4,100 to 4,600 square feet with average home prices of $1,740,000± to $2,100,000±. Adjustments of -$100,000 to $300,000 were applied to Land Sales 14, 14, 17 and 13, due to the differential in proposed product. In Group 5, the subject’s proposed product ranges from 5,200 to 5,900 square feet and $2,400,000± to $2,800,000±. Adjustments between $300,000 and $400,000 were applied to Land Sales 16, 17, and 13. Profit Participation The subject property will be subject to a Profit Participation Agreement between the master developer (Lennar) and the prospective home builder. In addition to the purchase price of each residential planning area/parcel, merchant builders shall pay to the master developer 70% of all net profit realized from the construction of homes. The net profit shall be paid at the time of home sales. Essentially, merchant builders are obligated to acquire the land on terms where they pay the master developer 70% of profits for distribution, after all costs (including 7% for profit). Based on the results of the residual analysis in the development method, calculation of this cost to the builder results in downward adjustments to the comparables with no profit participation agreement of 5%±, or -$90,000 to -$20,000. This adjustment is downward to reflect the burden the subject property carries for the profit participation. Entitlements/Risk It is often expected that due to risk, costs, and additional carry, lower prices would be paid for projects in the earlier stages of development (i.e., un-entitled land) than for projects closer to completion (i.e., Final Map). The subject product types were assumed for this analysis to have tentative map approvals. All of the comparable sales had tentative map or final map approval at the time of sale and/or delivery of the lots/units to the buyer. As all the comparables have similar entitlements compared to the subject property no adjustments were applied. Stage of Development For similar reasons to those stated above (carry costs, exposure, extended project life, etc.), it is expected that lower prices would be paid for projects in the earlier stages of development (i.e., raw land) than for projects closer to completion (i.e., finished lots). In this analysis, the subject lots were assumed to be in a superpad condition. The majority of the sales involved lots sold in a blue top or finished lot condition and rated similar to the subject in this regard. Land Sale 1 was reportedly purchased in raw or improved condition. An upward adjustment of $20,000 or approximately 4%± of the adjusted sales price, was applied to this comparable and considered reasonable for the additional risk.

RECONCILIATION – DETACHED RESIDENTIAL PRODUCT TYPES As previously mentioned, the subject detached product types were split into five groups represented by five adjustment grids. Group 1 (Products 29 and 30) applies to the subject’s smaller lot product between 2,400 and 3,300 square feet. For this group, before adjustments the sales prices for Comparables 3, 9, and 10 ranged from $399,000 to $499,000 per unit, with an average of $441,000 per unit. After having applied relevant quantitative adjustments to the comparable data, the adjusted price range narrowed to $381,500 to $436,000 per unit, with an average of $415,867. All of the sales were taken into consideration and the analysis of the comparable data would suggest that a per unit value of $410,000 would be reasonable for Products 29 and 30 via the sales comparison approach. Group 2 (Products 4, 5, 10, 31 and 32) applies to the subject lot product between 4,424 to 5,000 square feet. For this group, before adjustments the sales prices for Comparables 1, 4, and 8 ranged from $550,000 to $712,467 per unit, with an average of $622,181 per unit.

RECONCILIATION OF PRODUCT TYPES RESIDENTIAL LAND PRODUCT TYPES The appraisers applied two methods for estimating the finished land values for the residential product types intended for for-sale housing. As exhibited in the next table, the approaches provided various value indicators. With current and comparative land sales, the sales comparison approach is typically considered the most reliable indicator of value for subdivision land. The development method focuses on the development opportunity provided by the site under consideration and is not directly tied to the historical actions of buyers and sellers, as is the sales comparison approach. Although the subjectivity in many of these inputs tends to limit reliance on this technique, the development method is a tool relied upon by developers when estimating the amount they are willing to pay for a residential development site.

RECONCILED RESIDENTIAL FINISHED LAND VALUES BY PRODUCT TYPE (PER LOT BASIS) Heritage Fields Master Plan, Irvine, California

The sales comparison approach generally indicated lower finished lot values than the development method. The difference between the maximum and minimum value indications for each product group ranged from less than 0.5% (Product 31 – 4,500 square foot SFD) to 50%± (Product 16 – 7,700 square foot SFD). The finished lot value indications increased commensurate with progressively larger product type and/or lot size, as it would be reasonable to assume that larger and higher priced homes could feasibly be built on larger lot sizes.

Detached Residential For detached residential land, given the limited availability of comparative land sales in the overall Orange County submarket, the appraisers strongly considered the developmental method. However, the appraisers note the lack of 2006 land sales to support recent slowing in the residential housing market.

The sales comparison approach indicated a finished lot value of $525,000 per lot, and the developmental model indicated a value of $464,386 per lot. The appraisers placed greater reliance on the developmental method and reconciled at $470,000 per lot. Product 5 – The appraisers examined 52 lots of 4,725 square foot lot detached product.

approaches were considered in all cases. The resulting conclusions were deemed reasonable given the progression in the proposed lot and home sizes and home pricing for the subject’s product types.

As a final check to the reasonableness of the appraisers’ conclusions, the appraisers calculated the ratio of finished lot to average home price, including option revenues, as well as lot and model premiums, for the residential products. As shown in the following chart, the ratios ranged from about 46%± to 52%± on the detached residential product and 34%± to 41%± on the attached residential product.

FINISHED LOT / AVG PRICE RATIOS BY PRODUCT TYPEHeritage Fields Master Plan, Irvine, California

In general, for attached product there was an inverse relationship between the ratio and density, i.e. the ratio goes up as density goes down. This is expected as the overall costs (construction and profit) of higher density product is higher resulting in less allocation of land value to the overall price. In addition, for detached product the ratios generally increased with increasing unit size and larger lot sizes. Typically, ratios for medium to high density product will range from 15% to 35% with high density product at the lower end. Ratios for low density product will range from 40% to 50% with the majority falling toward the middle to higher end of this range for Orange County. Overall, the subject ratios were deemed reasonable and in line with the local submarket and were within the range of ratios indicated by comparable sales. The reader should note that the assumed average retail product prices for the subject lots were based on the appraisers’ hypothetical product and pricing. Any variations in product proposals by particular product types would likely affect the land/price ratio equation.

In order to derive appropriate values for use in the “as is” valuation analysis, it was necessary to deduct the estimated intract costs and fees due at permit for the detached product types. The result of this

VALUATION SUMMARY BY PRODUCT TYPEHeritage Fields Master Plan, Irvine, California

In the final step, the appraisers apply the conclusions of the product type analysis and apply it to the residential planning areas of Heritage Fields. The following table summarizes our revenue estimates.

As mentioned, Heritage Fields has 103 planning areas and 24 product types. The appraisers have analyzed the residential planning areas based on the 24 product types. In our analysis of 24 product types we chose a representative planning area population for each product type. As part of the methodology employed, for the residential planning areas, we conducted a developmental method and a sales comparison analysis for each product type, and reconciled a value indication for each product type utilizing these approaches. In the next step we are using the reconciled product type value indication and applying to all residential planning areas in the Heritage Fields Master-plan. As demonstrated in the Residential Revenues by Planning Area Summary Table, on the following page, the aggregate of land sale revenues from the various planning area valuations was $1,557,171,797.

This figure represents the aggregate of superpad land values excluding fees due at permit for the 2,891 residential units for Heritage Fields. Note, the 2,891 units does not include Faculty Housing (60 units), ETHIC (165 units), Apartments (117 units), and Low Affordable Housing (392 units), which would result in the total of 3,625 units. It is especially important to note that any substantial changes in the costs to finish the lots and/or superpad parcels, basically the builder’s costs, would affect the indicated land value indications. It was assumed that the costs provided were reasonably true and correct.

COMMERCIAL LAND PARCEL (INDUSTRIAL OFFICE / R&D) Heritage Fields includes two 30.3 to 35.9± acre sites within the LLD and various sites within the TOD ranging from 0.6 to 5± acres designated for industrial office / R&D facilities. There are a total of 68.6 acres within the LLD and 113.2 acres within the TOD. A search was made for land sales where the intended use was to develop industrial office or R&D buildings. Overall, five sales were deemed relevant and specifically analyzed herein. The five sales were analyzed on a price per square foot basis (net site area), which is typical for industrial land in this market. The industrial site sales comparison approach adjustment grid follows the ensuing discussion of the sales and the adjustment process. Sale 1, at $29.90 per square foot, sold in January of 2005, closing on June 23, 2005. The property consisted of a 22.18± acre parcel located in the Irvine Spectrum Technology Park, just west of Interstate 5, in Irvine. The area is a newly developed industrial area, which would be similar to the subject’s development, though overall superior in area. The site is being developed as a technology park with office / R&D buildings. Sale 2, at $52.29 per square foot, sold in July 2005. The property consisted of 1.44 acres, which was essentially the net acreage. The buyer is currently developing a commercial property on the site. Overall, this location is superior and is close to the freeway on-ramps to Interstate 5 and 405. The site was in a graded superpad condition at the time of sale. Sale 3, at $36.00 per square foot, was a 2.09 acre parcel which sold in May of 2005 and closed on September 30, 2005. This is a triangular shaped lot, located on the corner of Research Drive and Scientific Way, within a high-tech Industrial / R&D / Office park. The surrounding buildings are of a good quality, concrete tilt up construction, with good glass and some headquarter buildings were observed in the area. Overall, this location is superior and is close to freeway on-ramps to Interstate 5. The site, which has 2 story office buildings under construction, was in a graded superpad condition at the time of the sale. Sale 4, at $34.44 per square foot, sold in October of 2005 and closed on December 15, 2005. This was an 11.33 acre parcel with an easement and net acreage of 8.80 acres. The site, which is planned for development with several freestanding industrial office and R&D buildings, was in a graded superpad condition at the time of the sale. There was an existing church on the property, which added $0.25 per square foot to the land for demolition costs.

Sale 5, at $32.50 per square foot, sold in October 2006. The property consisted of a 1.44± acre parcel located in the Irvine Spectrum. The area is a newly developed industrial area, which would be similar to the subject’s development. The site is being developed with an office building.

Property Rights Conveyed No adjustments were warranted for property rights conveyed as all of the land data sold with fee simple property rights. Financing (Terms of Sale) None of the sales was reported to include atypical financing warranting adjustments. Conditions of Sale None of the sales was reported to include any conditions of sale. Market Conditions (Time of Sale) The comparable sales closed between June 2005 and October 2006. All commercial land uses have appreciated in Orange County submarket. A 12% annual adjustment was concluded based on the survey of all commercial property over the past four to five quarters (as discussed in the Market Conditions section). Adjustments are made from the date of sale. General Location Location takes into consideration the comparables’ and the subject’s physical orientation to the surrounding area, including proximity to local services and the quality and appeal of the community at large. All of the sales are rated similar in location. Specific Location Sales 1, 2 and 3 were rated superior in location with better access to the 5 and 405 freeways and local retail amenities. These sales were given a downward adjustment of 15% to 20%. The other sales were rated similar. Economy of Scale All other factors being similar, smaller parcels tend to command higher unit prices than larger parcels due to economies of scale and the more limited number of buyers that can afford to pay for larger parcels. The subject has two larger parcels (30.3 to 35.9± acre sites within the LLD). Comparable Sales 2 through 5 were adjusted upward because of their smaller size. Our adjustments ranged from 10% to 25%. Additionally, the subject includes parcels that range from .6 to 5 acres in size within the TOD (There is also a 2.5 acre parcel within the LLD). Sale 1 was given a 20% upward adjustment versus the subject smaller parcels. Utilities Utilities reflect a parcel’s accessibility to the local infrastructure. When taking into consideration utilities for commercial/institutional sites, electricity, gas, water, and sewer are all required in the typical market. All of the land comparables used in this analysis had utility services available, similar to the subject site.

Zoning / Use When analyzing this category of comparison, the appraisers took into consideration the subject’s land use designation, which allows an industrial office and R&D type product. Sales 1, 3 and 5 had similar office /

V A L U A T I O N S E R V I C E S 2 4 5

R&D type development, requiring no adjustment. Sale 2 is being developed with retail type uses, which fits the area. This sale is adjusted downward 10%. Sale 4 is being developed with an industrial park and was given a slight upward adjustment. Access / Exposure The subject sites are located in a master-planned community with average visibility and access. Sale 5 is located along a smaller cul-de-sac and was given a 10% upward adjustment versus the subject parcels. Stage of Development In this analysis, the subject site was assumed to be in a superpad condition. Sale 4 had an existing building that had to be demolished, adding to the cost of the land. This sale was adjusted according to the estimated costs for demolition. Community Facilities Assessment Bond assessments for the creation of infrastructure are typically passed on to the purchaser and add to the cost of the land. This additional fee is considered by the buyer as part of the land price. The subject has a $4.00 per square foot CFD. Variances in CFDs were used for the adjustments applied. RECONCILIATION – INDUSTRIAL / R&D - LARGER R&D PARCELS WITHIN LLD Before adjustments, the sales prices ranged from $29.90 to $52.29 per square foot. After having applied relevant quantitative adjustments to the comparable data, the adjusted prices ranged from $25.14 to $37.29 per square foot for the 30.3± to 35.9± acre sites within the LLD. We placed most emphasis on Sale 1 because of its similar size and Sale 5 because of its similar location and recent sale date. The data would suggest that the value of R&D land would fall in the range of $30.00 to $33.00 per square foot. After analyzing the available relevant data, a value of $30.00± per square foot was reconciled for the subject’s R&D sites in the LLD. Said value reflects the site being in a superpad condition. An adjustment grid follows this discussion. RECONCILIATION – INDUSTRIAL / R&D - R&D PARCELS WITHIN TOD Before adjustments, the sales prices ranged from $29.90 to $52.29 per square foot. After having applied relevant quantitative adjustments to the comparable data, the adjusted prices ranged from $36.34 to $45.30 per square foot for the .6 to 5.0± acre sites within the TOD. The data would suggest that the value of R&D land would fall in the range of $35.00 to $40.00 per square foot. After analyzing the available relevant data, a value of $37.00 per square foot was reconciled for the subject’s R&D sites in the TOD for the non-freeway exposed sites. A slightly higher value of $39.00 per square foot was reconciled for the freeway exposed sites. Said value reflects the site being in a superpad condition. An adjustment grid follows this discussion.

COMMERCIAL LAND PARCELS (AUTO CENTER) The Heritage Fields TOD consists of five parcels intended for auto center uses. The total area is 27.7± acres, and includes the following: Parcel T19-1 will have 5.2 acres, Parcel T19-2 will have 5.3 acres, Parcel T19-3 will have 5.6 acres, Parcel T19-4 will have 7.3 acres and Parcel T19-5 will have 4.3 acres. Parcels 1 and 2 will have Bake Parkway access and exposure and Parcels 3, 4 and 5 will have freeway exposure. According to the developer there is 102,000 square feet of entitlements that have been allocated to the auto center uses. Auto dealership land sales are not common given the maturity of the market. The Irvine Auto Center immediately adjacent has been built-out for over a decade. Additionally, neighboring auto centers within nearby communities have also been built-out for several years. Consequently, the appraisers have searched the general Los Angeles and Orange County area for sales of similar retail land and auto dealership use land. The appraisers found four land sales that were purchased for auto dealership use and one land sale that was purchased for retail use that is within an existing auto center. The five land sales were analyzed on a price per net square foot basis, which is typical for commercial land in this market. The sales comparison approach adjustment grid follows the ensuing discussion of the sales and the adjustment process. Sale 1, at $27.00 per square foot closed on December 12, 2006. This was a 4.20-acre parcel in the Foothill Ranch area, within the Foothill Ranch auto center. The site was originally purchased for auto dealership use but has since been purchased for future retail use. The site was in rough graded condition at the time of sale and had all offsite improvements to the site. The property is vacant. Sale 2, at $30.00 per square foot, sold in January of 2005 and closed on January 31, 2006. This is the purchase of a 6.40-acre parcel in a mature commercial district along the 60 Freeway in the City of Industry. According to the buyer’s the city was motivated to sell the property at a below market rate because of future retail tax benefits to be derived by the city. The property, which was in a rough graded condition at the time of the sale, had all offsite improvements to the site. The property was improved with a Chrysler/Jeep/Dodge auto dealership. The property was improved with the auto dealership at the time of inspection.

Sale 3, at $32.39 per square foot, closed on December 1, 2005. This was the acquisition of a 1.13-acre parcel located along North Hacienda Boulevard in La Puente. The property was vacant at time of sale. The area is a mature area and was purchased for additional parking area for a nearby dealership. Sale 4, at $47.51 per square foot, closed on May 1, 2005. This was a 3.01-acre parcel located on the along the north side of East Garvey Avenue and the 10 Freeway. The area is an existing auto dealership area and the site was purchased for expansion purposes by a nearby dealership. The site will house a service/parts facility for Mercedes Benz. The site was previously developed with a motel that was demolished by the buyer. The site has excellent visibility and immediate freeway access.

Sale 5, at $27.20 per square foot, closed on September 8, 2005. This was a 1.95-acre parcel located along Hatcher Avenue, north of Gale Avenue within the City of Industry. According to the buyer’s the city was motivated to sell the property at a below market rate because of future retail tax benefits to be derived by the city. The site will be used to develop an auto dealership. It was vacant at time of inspection. Property Rights Conveyed No adjustments were warranted for property rights conveyed as all of the land data sold with fee simple property rights. Financing (Terms of Sale) None of the sales was reported to include atypical financing warranting adjustments. Conditions of Sale The sales were considered similar in conditions of sale except for Sales 2 and 5 where the city was motivated to sell the property at a below market rate because of future retail tax benefits to be derived by the city. These sales were given upward adjustments of 10%. Also, Sale 4 which was an expansion of an existing facility and the buyers were more motivated to acquire the site than is typical. This sale was given a downward 10% adjustment. Market Conditions (Time of Sale) The comparable sold between May 2005 and December 2006. As stated earlier, all commercial land uses have appreciated in the Los Angeles and Orange County submarkets, as detailed in the Market Conditions section. A 12% annual adjustment was considered reasonable. General Location Location takes into consideration the comparables’ and the subject’s physical orientation to the surrounding area, including proximity to local services and the quality and appeal of the community at large. All of the sales were rated similar in general location. Specific Location The subject’s location adjacent to the Irvine Auto Center is considered to be superior to the older commercial districts of Sales 2, 3 and 5. Sale 1 is within Foothill Ranch which has a smaller trade area because of the mountains to one side. Sale 1 was adjusted upward 20%, while Sales 2, 3 and 5 were adjusted upward 15%. Economy of Scale All other factors being similar, smaller parcels tend to command higher unit prices than larger parcels due to economies of scale and the more limited number of buyers that can afford to pay for larger parcels. All of the sales were similar to the subject in size.

Utilities Utilities reflect a parcel’s accessibility to the local infrastructure. When taking into consideration utilities for commercial/institutional sites, electricity, gas, water, and sewer are all required in the typical market. All of the land comparables used in this analysis had utility services available, similar to the subject site. Zoning / Use When analyzing this category of comparison, the appraisers took into consideration the subject’s land use designation, which allows auto uses including auto dealership use. Only Sale 5 was considered to have an inferior industrial zoning and was adjusted upward 10%. As mentioned previously, the subject is limited in the building square footage allowed per the existing zoning. We have made a downward adjustment to all of the comparables for this condition of 5%. Access / Exposure Sales 1, 3, and 5 were rated inferior in access and were given upward adjustments from 5% (Sale 3), 10% (Sale 5) and 20% (Sale 1). Comparable Sale 4 was rated superior in access/exposure and was given a downward adjustment of 10%. Stage of Development In this analysis, the subject site was assumed to be in a superpad condition, similar to all of the comparables. Sale 4, however, had a sizeable existing motel building, which required demolition, estimated at $1.85 per square foot. Community Facilities Assessment Bond assessments for the creation of infrastructure are typically passed on to the purchaser and add to the cost of the land. This additional fee is considered by the buyer as part of the land price. The subject has a $4.00 per square foot CFD. Variances in CFDs were used for the adjustments applied. RECONCILIATION – AUTO CENTER PARCELS Before adjustments, the sales prices ranged from $27.00 to $47.51 per square foot. After having applied relevant quantitative adjustments to the comparable data, the adjusted prices ranged from $37.19 to $44.07 per square foot. The data would suggest that the value of auto center land would fall in the range of $40.00 to $43.00 per square foot. According to the brokers currently marketing the sites there are offers in for three of the sites. The 7.3-acre site (T19-4) has an offer in at $40.00 per square foot for an RV dealership use. Parcel T19-5 has an offer in at $45.00 per square foot for a custom auto use. After analyzing the available relevant data, a value of $40.00 per square foot, was reconciled for the subject’s non-freeway exposed sites and the larger freeway site. We have concluded to a slightly higher value for the freeway exposed sites of $43.00 per square foot. Said value reflects the sites being in superpad condition. An adjustment grid follows this discussion.

COMMERCIAL LAND PARCEL (EDUCATIONAL) One of the “cornerstone” land use designations within the Heritage Park project is “Institutional” land uses, which basically restrict development to educational-related institutions ranging from public and private schools to institutions of higher education as well as trade and technical schools. All of the Institutional uses are concentrated in the Lifelong Learning District. The total land area for Institutional uses is 238.5 acres with individual parcels ranging from 2.3 to 35.0 acres. A search was made for educational land sales throughout Southern California. Our search resulted in seven closed sales and a current offer involving sites that were purchased for the development of education-related uses such as public schools, private schools and libraries. The sales occurred between December 2004 and May 2007 and represent sites in the subject’s Orange County market as well as Los Angeles, San Diego, Riverside and Santa Barbara counties. The subject parcels that are designated for educational land uses range widely in size from 2.3 acres to 64 acres. The comparable data, in comparison, range from 0.6 acres to 7.34 acres in size. We have accounted for the wide range in size among the subject sites and accounted for the variations in size between the subject parcels and the comparables by segregating the subject parcels into three size cohorts and adjusting the comparables relative to the average size among those cohorts. We then made our conclusions for the three subject size cohorts based on these adjustments. SUMMARY OF LAND SALES (EDUCATIONAL) Sale 1 summarizes a current offer for a 5.08-acre site located in Santa Barbara, California. The site is currently improved with an auto dealership. The prospective buyer plans to demolish the existing improvements and construct a private school on the site. The property is zoned ES/PD/SD-2, which allows for residential and commercial uses. Zoning allows for the construction of 26,000 square feet. All utilities are in place. The current offer for the property is $12.6 million or $56.94 per square foot of land area. Sale 2 is the May 2007 sale of a 5.23-acre site located on the north side of San Marcos Boulevard, west of First Street, in the City of San Marcos, San Diego County. The property is identified by the San Diego Assessor as APN 219-210-40. The buyer intends to construct a high school on the site. The property was sold for $5 million or $21.95 per square foot of land area. The property was not previously developed; however, all utilities were reportedly in-place. Sale 3 corresponds to the January 2007 purchase of a 7.34-acre site located on the west side of El Fuerte Street, south of Poinsettia Lane, in the City of Carlsbad, San Diego County. The property is identified by the San Diego Assessor as APN 213-122-08 and 09. The corresponding street address is 6269 El Fuerte Street. Reportedly, the site will be constructed with an independent non-profit school for grades 7-12. The school will be constructed in phases, starting with grades 7 and 9 in 2007, grades 8 and 10 in 2008 and grades 11 and 12 will be added in 2009 and 2010. The property was purchased for $5,148,490 or $16.10 per square foot. The property was not previously developed but the site is served by utilities.

Market Conditions (Time of Sale) The sales closed between December 2004 and May 2007. We have also included a current offer to purchase (current as of July 2007). The land investment market in Southern California has been dominated by demand from residential developers over the past several years. In many cases, residential developers have purchased commercially and industrially zoned land and have taken the entitlement risk to re-zone for residential uses. Due to the competition in the marketplace, land values overall have risen sharply during the timeframe represented by the comparables. As the residential market has cooled over the past 18 months, land sales prices in most markets have stabilized. Based on land investment trends, we have applied an adjustment equal to approximately 10% per year for the data included in our survey, which represents a mix of zoning types ranging from commercial to industrial to special purpose uses. Location Due to the disparity among the educational land sales in terms of location, the general location adjustment considers the macro level locational considerations for the comparable relative to the subject. This adjustment also takes into consideration the comparables’ and the subject’s physical orientation to the surrounding area, including proximity to local services and the quality and appeal of the neighborhood, and proximity to transportation. The adjustments are summarized on the accompanying adjustment grid. Economy of Scale All other factors being similar, smaller parcels tend to command higher unit prices than larger parcels due to economies of scale and the more limited number of buyers that can afford to pay for larger parcels. The subject parcels that are designated for educational land uses range widely in size from 2.3 acres to 64 acres. The comparable data, in comparison, range from 0.6 acres to 7.34 acres in size. We have accounted for the wide range in size among the subject sites and accounted for the variations in size between the subject parcels and the comparables by segregating the subject parcels into three size cohorts and adjusting the comparables relative to the average size among those cohorts. We then made our conclusions for the three subject size cohorts based on these adjustments, which are summarized in three associated adjustment grids. Utilities Utilities reflect a parcel’s accessibility to the local infrastructure. For the development of educational facilities, electricity, gas, water, and sewer are all required. All of the land comparables used in this analysis had utility services available, similar to the subject site. No adjustments are warranted. Zoning – Land Use When analyzing this category of comparison, the appraisers took into consideration the subject’s land use. The zoning for the subject parcels restricts the use to educational uses. In contrast, the comparable data has underlying zoning that allows for a range of commercial or industrial uses. Some of the commercial zones even permit residential uses by right. Therefore, all of the comparable data are superior to the subject due to the alternative uses that are permissible on the sites even through they were all purchased for educational uses. We have made downward adjustments to the comparable data as shown in the accompanying adjustment grid.

Access / Exposure The subject educational parcels are located in the Lifelong Learning District of the master-planned community. Overall, the sites do not have extensive exposure, but will have good access and visibility from the project’s internal roadways. Overall, the district is accessible from SH 133. All of the sales are located in close proximity to major transportation corridors and have good visibility and access for the intended use. No adjustments were warranted for this category. Stage of Development In this analysis, the subject site was assumed to be in a superpad condition. Several of the comparables were improved or previously improved sites as indicated in the descriptions, while others were raw or undeveloped land that was served by municipal utilities. We applied adjustments to the comparables based on the condition of the property at the time of sale. Community Facilities Assessment Bond assessments for the creation of infrastructure are typically passed on to the purchaser and add to the cost of the land. This additional fee is considered by the buyer as part of the land price. The subject has a $4.00 per square foot CFD, which is deducted from the comparable sales which have no CFDs.

RECONCILIATION – EDUCATIONAL PARCELS Before adjustments, the sales prices ranged from about $14.75 to $59.49 per square-foot with an average of $33.88 per square foot. After having applied relevant quantitative adjustments to the comparable data, inclusive of the adjustment for CFD, the adjusted prices ranged from $15.44 to $31.39 for the adjustments based on the smallest subject size cohort, $9.52 to $24.56 for the medium-sized cohort, and $4.11 to $17.42 for the large subject parcel. In addition to the comparable data, we considered the terms of two written proposals we reviewed for educational land within the subject project. The first proposal is from California State University, Fullerton dated January 17, 2007 discussing the acquisition of a 20-acre parcel in the Lifelong Learning District for $30 million. This equates to $34.43 per square foot of land area prior to considerations for the CFD assessment of $4.00 per square foot. However, the proposal includes one of the existing buildings (Building 829) from the former Air Base, which is currently occupied by CSUF’s Irvine campus. Because this proposal includes an existing facility in which the offer is an occupant, this proposal can not be considered a market based indication of the value of the underlying land. The second proposal was received from Lutheran High South dated April 17, 2007 (appraisers copy was not complete and did not include a signature page). The letter expressed the school’s interest in purchasing approximately 35 acres in the Lifelong Learning District for $146 per square feet of FAR and requests 225,000 to 250,000 square feet of FAR. The implied land pricing is therefore in the range of $32,850,000 to $36,500,000 or approximately $21.55 to $23.94 per square foot of land area. This offer is considered an indication of the market value of the subject’s educational land and we have considered this proposal in our final land value estimate. After analyzing the available relevant data, a value of $25.00 per square-foot was concluded for the smaller subject parcels, $20.00 was selected for the medium-sized subject parcels and $15.00 per square-foot was selected for the largest subject parcel. The aggregate market value is $199,003,000 (rounded) as shown in the following table. The said value reflects the site being in a superpad condition.

COMMERCIAL LAND (EDUCATIONAL) VALUATIONHeritage Fields, Irvine, California

COMMERCIAL LAND PARCELS (OFFICE) The Heritage Fields project includes 10.5± acres of office designated land within a single parcel, identified as Parcel T7 in the TODD. The office site will have a good corner location at the intersection of two of the project’s new interior arterial roadways. The office site is also in proximity to the Irvine Spectrum, a notable office node in the subject’s Irvine submarket. A search was made for land sales where the intended use was to develop office buildings. Overall, six sales were found which were deemed relevant and specifically analyzed herein. The sales were analyzed on a price per square foot basis (net site area), which is typical for commercial land in this market. We also evaluated the sales on a price per square foot of buildable area for those data items for which such information was available. SUMMARY OF LAND SALES (OFFICE) Sale 1 refers to the January 2007 sale of a 2.61-acre site located at the northwest corner of State College Boulevard and Rampart Street in the City of Orange, California. At the time of sale, the property was improved with a former hotel but the improvements were allocated no value. The location is adjacent to the Platinum Triangle and high-density residential land uses are in development in the immediate location. The site is rectangular in shape and is positioned across Rampart Street from a newly constructed apartment community. On/off ramp service to the I-5 freeway is within one block of the site. The buyer paid an all cash price of $9,700,000 or $85.32 per square foot for the site. The site is zoned C-2, Commercial, by the city of Orange. Future development plans are unknown as of the date of this appraisal. Sale 2 corresponds to the August 2006 sale of a 6.25-acre site located along the west side of Jamboree Road just south of Teller Avenue in the City of Irvine. The property was improved with a vacant industrial building. The site has a mid-block location along the west side of Jamboree Road between Michelson Drive to the north and Dupont Drive to the south. The site is considered in the “path of

development” and was acquired by Jamboree Hines, LLC for an all cash price of $21,350,000 or $78.42 per square foot. The site is located in the IBC-5.1 zone within the City of Irvine which allows for commercial development. Hines planned to assemble “trip” counts to the site that would allow for the eventual development of up to 250,000 square feet of office. The indicted per-buildable-square-foot sale price equals $85.40. Sale 3 refers to the August 2006 sale of a 3.12-acre site located at the southwest corner of Laguna Canyon Road and Waterworks Way in the Spectrum Area of the City of Irvine. The site was owned by Irvine Medical Plaza LLC and was sold to Irvine Medical Holdings for an all cash price of $9,329,000 or $68.66 per square foot. The buyer intended to develop a three-story medical office building and related surface parking improvements. The site is adjacent to major medical land uses including Kaiser Permanente and Irvine Medical Center, which are both approximately two blocks south. The site is in the MS zone of the city of Irvine, which allows for medical office development.

Sale 4 corresponds to the November 2005 sale of a parcel located along the north side of Katella Avenue east of Lewis Street in the City of Anaheim. The property consists of a 4.88-acre site improved with an older industrial building which was allocated no value at the time of the sale. The site is zoned ML (light manufacturing) by the City of Anaheim, but is a part of the Platinum Triangle Mixed Use Overlay Zone. The buyer intends to develop the site with a high density residential project, the scope of which has yet to be determined. The buyer paid an all cash price of $14,000,000 or $65.86 per square foot for the property. Sale 5 refers to the October 2005 sale of a prime development parcel located along the east side of Von Karman Avenue in the City of Irvine. The property consists of a 3.98-acre parcel and trip allocations for the development of roughly 159,000 square feet of office space and related parking improvements. The property was acquired in January 2005 by Sanmina for office development. However, residential development activity was very strong during 2005 and the site’s highest and best use was determined (at the time) to be for high-density residential development. Allergan Pharmaceuticals, which owns and occupies adjacent property, acquired the site from Sanmina in order to control its future development. Allergan paid an all cash price of $12,000,000 or $70.17 per square foot for the property. The price paid represents a 99.2% increase over the $6.1 million price paid just 10 months prior. Sale 6 is the June, 2005 purchase of the site for 2211 Michelson, which is currently under construction. The property was acquired by a partnership consisting of Hines and Crescent Realty, who is developing a 12-story, 265,277 square-foot office building on the site. The property is part of the larger “Irvine Business Complex,” which was previously known as “Koll Center Irvine.” The property was entitled at sale for the proposed development. The acquisition also include an undivided interest in common areas for the larger Irvine Business Complex, which results in a “grossed up” land area of 3.62 acres including the allocation of common areas. The sales price of $12,000,000 equaled $45.24 per square foot of proposed building area (rentable), and $228.44 per square foot of “pad” area including only the 1.206-acre parcel owned in fee. Including the allocated portion of the common area parcel, however, the price per square foot of land area equals $76.10 per square foot of land area (refer to accompanying summary chart). SUMMARY OF ADJUSTMENTS (OFFICE) Property Rights Conveyed No adjustments were warranted for property rights conveyed as all of the land data sold with fee simple property rights. Financing (Terms of Sale) None of the sales was reported to include atypical financing warranting adjustments. Conditions of Sale None of the sales was reported to include any conditions of sale.

Market Conditions (Time of Sale) The comparable sales closed between June 2005 and January 2007. All commercial land uses have appreciated in Orange County submarket over this timeframe. A 10% annual adjustment was concluded based on the survey of all commercial property over the past four to five quarters (as discussed in the Market Conditions section). Adjustments are made from the date of sale. Location Location takes into consideration the comparables’ and the subject’s physical orientation to the surrounding area, including proximity to local services and the quality and appeal of the community at large. For office land sales, we have also taken into account the relative strength of the office submarket of the comparables relative to the subject’s submarket. Comparables 2, 3, 5 and 6 are located in the subject’s Irvine market; however, the relative locations of these comparables are superior to that of the subject. Comparable 1 is located in Orange, which is an inferior location, but this comparable is located adjacent to the Platinum Triangle which strengthens the specific location of this comparable. Comparable 4 is located in Anaheim which is inferior overall. Adjustments were made to the comparables as shown in the adjustment grid. Economy of Scale All other factors being similar, smaller parcels tend to command higher unit prices than larger parcels due to economies of scale and the more limited number of buyers that can afford to pay for larger parcels. The subject’s office site totals 10.5± acres. The comparables ranged in size from 1.21± to 6.25± acres, which is less than the size of the subject. The comparable sales were adjusted downward for their smaller land area relative to the subject as shown in the accompanying adjustment grid. Utilities Utilities reflect a parcel’s accessibility to the local infrastructure. For the development of professional office space, electricity, gas, water, and sewer are all required. All of the land comparables used in this analysis had utility services available, similar to the subject site. No adjustments are warranted. Zoning / Use When analyzing this category of comparison, the appraisers took into consideration the subject’s proposed land use, which will be for office development. Though land sales with different zoning classifications were utilized to value the subject site, all of the zoning classifications for the sales considered allowed for professional office development by right. Sale 4 was purchased unentitled for residential development. The buyer intended to pursue re-zoning for the site that would permit residential uses, but none were permitted at the time of sale. All of the other comparables were purchased with plans for development of office buildings or with undetermined plans. The subject property and all of the comparable data items permit office development by right. The subject; however, does not permit any uses other than office development, which is somewhat limiting relative to the comparables. Furthermore, the overall density of the subject at .35 FAR is considerably less than the comparables (for which information is available) that range from .91 to 1.68 FAR. Due to the somewhat more restrictive flexibility in use, and the lower maximum permissible density of the subject site, we have applied downward adjustments to the comparable data.

Access / Exposure The subject sites are located in the TODD of the Heritage Fields master-planned community. Upon completion of the community’s infrastructure, the subject office site will have good visibility and access from two of the new arterials. All sales were similar in street frontage, access and exposure, and no adjustments are warranted. Stage of Development In this analysis, the subject site was assumed to be in a superpad condition, similar to all of the comparables. No adjustments were necessary. Community Facilities Assessment Bond assessments for the creation of infrastructure are typically passed on to the purchaser and add to the cost of the land. This additional fee is considered by the buyer as part of the land price. The subject has a $4.00 per square foot CFD, which is deducted from other sales which have no CFDs.

RECONCILIATION – OFFICE PARCELS The preceding data included six closed sales (excluding multiple sales involving the same site) in the Central Orange County market over the past two years. Four sales (2, 3, 5 and 6) are located in the Irvine submarket of the Greater Airport Area with the remaining sale (4) is in the Anaheim submarket. Four of the closed sales (2, 3, 5, and 6) were sites acquired for office development, while Sale 4 was acquired for residential use but was not entitled for that use at the time of sale. The per square foot prices based on land area range from (rounded) $66 to $85 prior to any adjustment, with the pricing for Sale 6 based on the site area including allocated interest in the common area. Excluding allocated common area, the pricing for this sale is $228 per square foot. The sales with available FAR data, or Sales 2, 5 and 6, show a range in FAR pricing from (rounded) $45 to $85. While not a precise “matched pair”, Sales 2 and 6 provide an indication of the increase in FAR pricing for office use from 2005 to 2006. Sale 6 involved the purchase of an entitled office site for $45 per FAR by a Hines entity; Sale 2 was also acquired by Hines, and involved an as-yet un-entitled site for office development in the same market location (Irvine) as Sale 6, at a significantly higher price per FAR of $85. We note that the density (FAR) for Sale 6 is higher than for Sale 2, however, which typically will result in a downward adjustment in the FAR price (and an upward adjustment in the price per land foot). After having applied relevant quantitative adjustments to the comparable data, the adjusted prices ranged from $32.31 to $45.27 per square-foot with an average of $41.41. To the best of our knowledge, the subject ownership/developer has not received any offers or letters of intent for the subject office land. We have therefore relied on the comparable data to estimate the value of the subject site. The greatest weight was given to Sales 2, 3 5 and 6 which are located in the subject’s Irvine market; however, these sales enjoy stronger locations due to their concentration in an existing, well established office market. After analyzing the available relevant data, a value of $40.00± per square foot, or a total of $18,295,000 was reconciled for the subject’s office site T7 (10.5 acres) within the TODD. Said value reflects the site being in a superpad condition. Said value also considers the $4.00 per square foot in CFD obligations attributed to commercial parcels in the Heritage Fields MPC.

V A L U A T I O N S E R V I C E S 2 7 5

COMMERCIAL LAND PARCELS (RETAIL) Heritage Fields’ LLD consists of five individual parcels intended for retail uses. The total land area designated for retail uses is 40.5± acres, and includes three parcels in the LLD - L17 (19.6 acres), L20 (9.2 acres), and L21 (4.2 acres) – and two parcels in the TODD – L1c (6.0 acres) and L12e (1.5 acres). The retail parcels in the LLD will have frontage and exposure from Trabuco Road and are situated at the primary entrance to the project area from SH 133. The two retail parcels located in the TODD will most likely be improved with uses that serve the surrounding R&D and automotive development that dominates this planning area. In contrast, the retail development that is most likely for the LLD retail sites will be positioned to serve the large resident and student population in this district based on the designated land uses. We have searched the general Orange County area for sales of similar retail land sales. Our search produced very limited results. There has been a very limited investment market for retail land sales over the past several years. We have considered the terms of five comparable sales in our analysis. The sales were analyzed on a price per square foot basis (net site area), which is typical for commercial land in this market. SUMMARY OF LAND SALES (RETAIL) Sale 1 corresponds to the April 2006 sale of a 1.2-acre site located at the northeast corner of Fabricante and Alicia Parkway in the City of Newport Beach. The property is zoned NC-C, Commercial, and retail uses are permitted by right. The property was improved with a vacant freestanding retail building at the time of sale, which was intended for demolition (former auto center). The site is fully improved and served by all utilities. The property was purchased by a local buyer for $4,230,000 or $80.92 per square-foot subsequent to a formal marketing effort. Sale 2 corresponds to the February 2006 purchase of a 3.03-acre site located at the intersection of Katella Avenue and Walker Street in the City of Cypress. The property is located to the east of the Los Calamitous Race Track. The corner site features frontage on Walker Street and Katella Avenue. The property was formerly improved and is fully served by all municipal utilities. The Cypress Redevelopment Agency sold the property to Newport Beach based Jones Cypress Plaza, LP who intends to construct a small retail center on the site. The purchase price of $2,493,500 is equal to $18.89 per square foot of land area. Sale 3 corresponds to the August 2005 sale of a 20.72-acre site located at the southwest corner of Hyland Avenue and Sunflower Avenue in the City of Costa Mesa. The property fronts the San Diego Freeway, which forms the property’s southernmost boundary. The site features extensive frontage along both Hyland Avenue and Sunflower Avenue. The property is the site of a former State Farm Insurance headquarters building. State Farm sold the property to South Cost Home Furnishings of Irvine. The buyer intends to demolish the existing improvements and redevelop the site with an eight-building, 300,000 square-foot home furnishings center that will house approximately 30 retailers. The purchase price of $29,000,000 is equal to $32.13 per square-foot of land area. The property was fully improved and fully served by public utilities.

Sale 4 corresponds to the May 2005 sales of a 0.73-acre site located at the northwest corner of Younger Drive and Knott Avenue in the City of Buena Park. The site is the location of a former carwash that was to be demolished. The property was purchased by Akash Investments of Corona for the development of a small retail development. The purchase price of $1,200,000 is equal to $37.50 per square foot of land area. The site is rectangular in shape with frontage along both Younger Drive and Knott Avenue. The site is fully served by public utilities. The C-S zoning permits retail development by right. Sale 5 corresponds to the March 2005 sale of a 1.66-acre site located along the north side of Los Alisos Boulevard between El Toro Road and Melina Road, south of Highway 241 in the City of Mission Viejo. The site has approximately 715 feet of frontage along Los Alisos Boulevard. The property was purchased by Anaheim-based Milan Real Estate Investments III from Lancaster Realty Holdings, LP for the development of a retail and office project. Plans include the construction of three small buildings of approximately 4,000 square feet each. Two retail uses and a medical use were contemplated. The property was fully served by public utilities. The purchase price of $2,000,000 is equal to $27.59 per square foot of land area. SUMMARY OF ADJUSTMENTS (OFFICE) Property Rights Conveyed No adjustments were warranted for property rights conveyed as all of the land data sold with fee simple property rights. Financing (Terms of Sale) None of the sales was reported to include atypical financing warranting adjustments. Conditions of Sale None of the sales was reported to include any conditions of sale. Market Conditions (Time of Sale) The comparable sold between March 2005 and April 2006. No more current retail land sales transactions could be located. As stated earlier, all commercial land uses have appreciated in Orange County submarket, as detailed in the Market Conditions section. A 10% annual adjustment was considered reasonable from the date of the sale. Location Location takes into consideration the comparables’ and the subject’s physical orientation to the surrounding area, including proximity to local services and the quality and appeal of the community at large. The subject property is bracketed by the data in terms of location. Sale 1 is located in Newport Beach, which is quite superior, and Sale 2 is in Cypress, a somewhat inferior location. The subject’s “village” or neighborhood concept will result in a prime location for retail and is considered to be superior to the older commercial districts of Sales 4 and 5.

Economy of Scale All other factors being similar, smaller parcels tend to command higher unit prices than larger parcels due to economies of scale and the more limited number of buyers that can afford to pay for larger parcels. The comparable sales bracket the subject in size, which has individual parcels ranging widely from 1.55 to 19.60 acres. We adjusted the comparable data considering the “average” size of the subject retail parcels. Subsequent to adjustment, we concluded a range of per square-foot pricing for the subject’s individual retail sites that takes into account the size variations among the parcels. Utilities Utilities reflect a parcel’s accessibility to the local infrastructure. When taking into consideration utilities for commercial/institutional sites, electricity, gas, water, and sewer are all required in the typical market. All of the land comparables used in this analysis had utility services available, similar to the subject site. No adjustments are required. Zoning / Use When analyzing this category of comparison, the appraisers took into consideration the subject’s land use designation, which allows for traditional retail development. All of the comparables were permitted for retail development by right, and were purchased with the intention of retail construction. No adjustments to the comparable data were warranted. Access / Exposure The subject sites are located in a master-planned community with average visibility and access. All of the sales were essentially similar to the subject in this respect. Stage of Development In this analysis, the subject site was assumed to be in a superpad condition, similar to all of the comparables. Costs for the demolition of existing improvements on the comparable sites that were improved are not known. Costs to demolish any existing improvements on the subject’s retail sites are also not known. Adjustments, therefore, have no been considered. Community Facilities Assessment Bond assessments for the creation of infrastructure are typically passed on to the purchaser and add to the cost of the land. This additional fee is considered by the buyer as part of the land price. The subject has a $4.00 per square foot CFD.

RECONCILIATION – OFFICE PARCELS Before adjustments, the sales prices ranged from $18.89 to $80.92 per square foot. After having applied relevant quantitative adjustments to the comparable data, the adjusted prices ranged from $23.51 to $45.85 per square foot. Emphasis was applied to Sale 3 due to the proximity to the subject and lower net adjustment, and Sales 4 and 6 due to their lower net adjustment. The data for these three sales would suggest that the value of the subject retail land would fall in the range of $34.00 to $38.00 per square foot. After analyzing the available relevant data, a value of $35± per square foot, was reconciled for the subject’s retail sites, on average. The L7 site, at 19.6 acres, was further adjusted downward for size and we estimated a $30.00 per square-foot value for this parcel. Likewise, our conclusion was adjusted upward for Parcel T12e which is 1.55 acres in size. We estimated a per square-foot land value of $40.00 for this parcel. Said value reflects the sites being in superpad condition. A summary of the estimated retail land values by parcel is as follows.

V A L U A T I O N S E R V I C E S 2 8 2

COMMERCIAL LAND PARCELS (AGRICULTURAL) Heritage Fields’ LLD consists of three individual parcels intended for agricultural uses. The total land area designated for retail uses is 175.7 acres. Two agriculturally designated parcels are located in the LLD - L1 (141.3 acres) and L2 (21.9 acres). The third parcel is locate din the TODD – T4 (12.5 acres). The agricultural parcels in the LLD form the northernmost boundary of the property and act as a buffer between the more intensely developed portions of the project and the UC Research Center and Marshburn Basin. The Agricultural parcel in the TODD is a parcel along the eastern project boundary adjacent to the golf course and the wildlife corridor. Our research suggests that a considerable amount of land sale activity involving agriculturally zoned property has occurred in Orange County as well as the neighboring counties of Los Angeles and San Diego. However, it is common practice in most jurisdictions to permit low density residential development by right in A-zoned districts. Generally speaking, home sites of one to ten acres are permitted in the A zones in various communities. The subject Agriculture sites, in contrast, have no future residential development potential. We have also reviewed a number of sites purchased for permanent open space. Again, these sales are not comparable with the subject Agricultural sites because the subject parcels afford a buyer economic opportunity and have income generating potential. We have, therefore, limited our selection of comparable sales to those with known agricultural uses that were known to be in place at the time of sale and continued in the near term. We have also included sales of agriculturally zoned land whose buyers had no near-term plans for pursuing residential development. The sales were analyzed on a price per acre basis (net site area), which is typical for large parcel agricultural land in this market. SUMMARY OF LAND SALES (AGRICULTURAL) Sale 1 corresponds to the April 2007 sale of a 33.45-acre site located along the south side of Agoura Road, west of Reyes Adobe Road in the City of Agoura Hills, Los Angeles County. The site is irregular in shape, with a rolling topography. The property was previously undeveloped. The site features 1,120 feet of frontage along Agoura Road. The property is zoned SP by the City. The property was purchased by the Conrad N. Hilton Foundation from the Tohl Family Trust subsequent to a formal marketing effort. The purchase price of $3,500,000 id equal to $104,634 per acre. The buyer purchased the property in order to construct a new 35,000 square-foot headquarters for their charitable foundation. Sale 2 corresponds to the March 2007 sale of a 106-acre site located along the south side of Bandy Canyon Road in Escondido, San Diego County. The property is zoned A70 and was previously undeveloped. The property was purchased by CGA Properties, LLC from the Fenton JB Family Trust for $3,150,000 or approximately $29,717 per acre. The property was purchased for long-term investment. The site has limited frontage along Bandy Canyon Road, but the bulk of the site is interior. Topography is rolling. Utilities are in the street but not throughout the site.

Sale 3 corresponds to the May 2006 sale of an 80.17-acre site located along the east side of Betsworth Road at the eastern terminus of Aere Road in Valley Center, San Diego County. The property is zoned A70 and was improved with a nursery facility (Santa’s Forest Nursery) at the time of sale. The buyer is an owner/user as was the seller. The property was purchased for $2,475,000 or $30,872 per acre. The site has 1,341 feet of frontage along Betsworth Road, which provides good access. Utilities are available throughout the property. Sale 4 corresponds to the March 2006 sale of a 362.0-acre site located along both the east and west sides of Valley Center Road in Valley Center, San Diego County. The property is zoned A70 and was improved with a horse boarding facility at the time of sale. The property was purchased by MLSK LLC of San Diego after a formal marketing effort. The buyer and seller are both owner/user investors. The property is fully served by public utilities. There are several structures on the site including two caretaker homes, a cottage, 9 apartment units, 2 barns and a 6-room bunkhouse. The purchase price of $11,665,000 is equal to $32,224 per acre. No allocation between the value (if any) of the existing improvements and the underlying land was available. Sale 5 summarizes the terms of a January 2006 sale involving a 14.71-acre site located along the south side of El Camino Real, south of San Dieguito Road in San Diego, San Diego County. The property is zoned A1-10 and was unimproved at the time of sale. The property was purchased by Strawberry Hut LLC of San Diego. Future plans for the property were undetermined. The purchase price of $2,700,000 is equal to $183,548 per acre. Topography is rolling and utilities are available in the street and may be available throughout the site. SUMMARY OF ADJUSTMENTS (AGRICULTURAL) Property Rights Conveyed No adjustments were warranted for property rights conveyed as all of the land data sold with fee simple property rights. Financing (Terms of Sale) None of the sales was reported to include atypical financing warranting adjustments. Conditions of Sale None of the sales was reported to include any conditions of sale. Market Conditions (Time of Sale) The comparable sold between January 2006 and April 2007. As stated earlier, nearly all commercial land uses have appreciated in Southern California over the past 12 months, however, the pace of appreciation for large tracts of previously undeveloped or nearly undeveloped land have not experienced the same rate of appreciation as urban infill sites with clear entitlement potential. An annual adjustment of approximately 8% per year was considered reasonable for the comparable data.

Location Location takes into consideration the comparables’ and the subject’s physical orientation to the surrounding area, including proximity to local services and the quality and appeal of the community at large. No comparable sales were located within the subject’s Orange County market area. The data from Los Angeles is considered superior in location, while the San Diego County data is considered inferior, with the exception of Sale 5 which is located in the City of San Diego and is considered somewhat superior. The subject’s agricultural sites will be situated within the context of a comprehensive master-planned community. In comparison, the comparable sales are generally located in outlying areas with large concentrations of other similar uses. We have considered the context of the subject relative to the comparables in our overall location adjustment. Economy of Scale All other factors being similar, smaller parcels tend to command higher unit prices than larger parcels due to economies of scale and the more limited number of buyers that can afford to pay for larger parcels. The comparable sales range in size from 14.71 to 362.00 acres, which compares to the subject’s parcels ranging from 12.5 to 141.3 acres. We adjusted the comparable sales considering the 12.5 and the 21.9 acre subject parcels. Subsequent to the overall adjustment, we made a further adjustment to our per acre indication for the subject’s 141.3-acre parcel. Utilities Utilities reflect a parcel’s accessibility to the local infrastructure. When taking into consideration utilities for commercial/agricultural sites, electricity and water are generally required in the typical market; however, the entire site does not necessarily need to be fully serviced. Gas and sewer are not considered required utilities. All of the land comparables used in this analysis had utility services available, similar to the subject site. Zoning / Use When analyzing this category of comparison, the appraisers took into consideration the subject’s land use designation, which allows for agricultural uses. Unlike most of the comparable data, residential uses are not permitted in the subject’s agricultural parcels. We applied a downward adjustment to the comparable data, which have potential for development of alternative non-agricultural uses.

Access / Exposure The subject sites are located in a master-planned community with average visibility and access. All of the sales were essentially similar to the subject in this respect. Sale 1 has extensive frontage along a primary roadway in proximity to Highway 101. A downward adjustment for this comparable’s superior access was warranted.

Stage of Development In this analysis, the subject site was assumed to be in a superpad condition. In contrast, the comparable data represents sites that are not served by the same level of infrastructure as the subject will be. We accordingly have adjusted four of the sales upward. Community Facilities Assessment Bond assessments for the creation of infrastructure are typically passed on to the purchaser and add to the cost of the land. The developer reported that the agricultural land will not be subject to additional special assessments. The comparables were similar in this respect and not adjustments were applied.

RECONCILIATION – AGRICULTURAL PARCELS Before adjustments, the sales prices ranged from $29,717 to $183,548 per acre. After having applied relevant quantitative adjustments to the comparable data, the adjusted prices ranged from $40,920 to $90,857 per acre and averaged $60,047 per acre. After analyzing the available relevant data, a value of $85,000± per acre, was reconciled for the subject’s smaller agricultural parcels, consistent with the upper end of the range, which corresponds to Sale 5. Sale 5 is the most similar in size to the subject’s smaller agricultural parcels. As previously mentioned we applied a further downward adjustment to this estimate to account for the larger size of subject parcel L1 and concluded at $60,000 per acre for this subject parcel. Our estimates of value for the subject agricultural parcels are summarized as follows:

COMMERCIAL LAND PARCEL (EXPOSITION) The Heritage Fields project includes a 215.7-acre parcel (L27) located in the LLD that is planned for development of an Expo Center. As discussed in the Property Description Section, the Expo Center use is limited to commercial recreation, demonstration shows, training venues and a variety of other recreation and learning activities. We have searched for sales of land throughout California that are intended for a similar use. Our search resulted in no relevant, comparable data from which to appropriately value the subject Expo Center site. Our research into similar uses suggests that typically, quasi-governmental agencies or authorities are established to construct and operate convention or exposition-type facilities in major markets. Los Angeles and San Diego, for example, both have quasi-governmental authorities that developed the convention centers in these cities. A possible use for the subject’s designated Exposition property could be an event area that would host live music performances or other public arts and entertainment events. Similar facilities exist in Southern California such as the Gibson Amphitheater at Universal Studios, the Verizon Wireless Amphitheatre in Irvine. Generally, these facilities are subject to long-term operating agreements with entities like Live Nation that specialize in booking acts and managing ticket sales and operations. Absent specific plans for the development of the subject’s Exposition-designated site that could possibly result in a valuation via land residual analysis, we have considered the land value indications from the agricultural land sales we considered previously. The value indications for the subject’s agricultural sites are in a range of $60,000 to $85,000 per acre. We applied a 15% downward adjustment to the high end of these indications to account for the size of the subject’s Exposition site, which is 215.7 acres. We applied a further downward adjustment of 5% to account for the limited use and ultimate limitations on the possible buyer pool for this type of development site. The resulting value indication for the subject Exposition site is a rounded $65,000 acre of land area or $14,020,500.

COMMERCIAL LAND (EXPOSITION) VALUATIONHeritage Fields, Irvine, California

The owner’s business plan indicated that a September 2011 absorption or sell-off date was anticipated for the Exposition site. To the best of our knowledge, the ownership is not currently in discussions/negotiations with a possible buyer. Based on our understanding of the restricted use of this site, and given the very finite number of market buyers or the limitations of the forming of a quasi-public entity to purchase such a site, we have extended the absorption by one year.

COMMERCIAL LAND PARCEL (CEMETERY) The Heritage Field’s project includes a 73.2-acre cemetery site within the LLD. It is our understanding that the subject ownership has negotiated the terms of a purchase and sale agreement with a buyer for this site. Due to issues of confidentiality, the ownership did not share a copy of this agreement with the appraisers. It has been represented to us that the purchase price for the 73.2 acre site is $20,054,795 or approximately $6.29 per square foot of land area. We searched for sales of land intended for use as a cemetery or other related use. Our search produced no results in the State of California. We have maintained the records of three sales in our files. The sales represent sites in Houston, TX; Aberdeen, MD and Boca Raton, FL. These sales, while not comparable to the subject for purposes of valuation, demonstrate that there is support in the marketplace for sales of cemetery sites such as the subject’s. For purposes of our analysis, we have utilized the owner/developer’s reported contract pricing and timing for the sale in our analysis.

NATIONAL GOLF MARKET ANALYSIS OVERVIEW For the last several years, the golf industry has continued to suffer from golf course oversupply. The majority of markets throughout the United States are oversupplied and demand has been relatively flat for over five years. Golf player retention and player participation rates continue to be the challenges for the business of golf. Over the last century, the golf market has experienced three boom periods; the 1920s, the 1970s and the 1990s. In the 1990s the majority of golf course development was connected to residential developments. Two sectors that experienced very significant increases in supply were the premium daily fee and the premium private courses. The source of our national golf course market data is the National Golf Foundation (“NGF”). The NGF publishes annual reports on the supply and demand conditions for selected markets throughout the United States, with the most recent being the Golf Facilities in the U.S., 2007 Edition (incorporating data available through 2006). Despite the oversupply of golf courses many developers continue to add courses as an amenity to master-planned communities, regardless of the supply/demand characteristics of the market. In fact, 67% of all new facilities opened in 2006 were associated with real estate development, with either a hotel or master-planned community. However, new golf course construction slowed considerably in the 21st century. The National Golf Foundation (NGF) reported that in 2006, 119.5 18-hole equivalent golf courses opened, which reflects a decrease from 125 new courses opened in 2005, 146 new courses in 2004 and 171 new courses in 2003. Clearly, course openings are showing a declining trend. NGF data indicates that 283 golf courses are currently under construction, which will open in 2007-2008. The NGF estimates that 110-120 new courses will open in 2007 and between 100 and 125 courses will open annually for the next few years. Course closures are becoming an increasingly important part of the equation in terms of supply. In 2006, 146 18-hole equivalent courses closed throughout the U.S., causing a net decrease in course supply for the first time since World War II. While the trend in openings is declining, the trend in closures is increasing, up from 93.5 in 2005 and 62.5 in 2004. The primary reason for the closings is land redevelopment to residential or commercial uses, i.e. a change in highest and best use. The majority (97%) of closures were public facilities, with the majority of those facilities being executive/short courses and 9-hole facilities. With a net decrease in golf facilities, and with most being in the range of quality for beginning and intermediate golfers, some concern has been expressed about player development, and the access to lower quality public facilities that enable beginners to play. The NGF also divides the national market into nine-submarkets. The subject property is located in the State of California, which is in the Pacific market. The Pacific market includes the states of Alaska, Washington, Oregon, California, and Hawaii. This market comprises 9.3% of the total national supply of golf facilities in the United States. At the year end 2006, there were 921 golf courses (facilities) in the

State of California, which is the second regarding the number of facilities just behind the state is Florida which has 1,075 golf courses. In the 1990-2000 decade, most of the golf club sales and investment activity was attributed to sales to owner operators or club membership upon sellout of the residential component of the overall project. Also, there were numerous sales of clubs under financial distress related to failed residential communities. There still remains a significant presence of private golf clubs located primarily in gated residential communities that will be targets for sale, either to outside operators or conversion to member ownership. Golf investment continues to be attractive to traditional golf investor/operators, but also to Wall Street due to their access to capital and their need to get higher returns than traditional real estate. Certain buyers have emerged such as KSL, formerly KSL Fairways, which purchased the ClubCorp portfolio for $1.8 billion. CNL Properties has also been a buying mode, acquiring over 20 golf courses in the last two years. The industry is speculating whether KSL/ClubCorp will be a buyer, wishing to expand its portfolio, or a seller, divesting of certain assets that do not fit their corporate model. Certainly, CNL will continue to be a buyer in the market, focusing on existing profitable facilities in markets that fit their business model. Further, it is widely known that the American Golf portfolio is likely going to be on the market in 2007. While some consolidation is occurring, the industry remains very fragmented, with over 80% of all facilities owned by small one or two property operators. Golf club financing is typically available from golf oriented lenders with strict guidelines including Textron Financial Corp., Pacific Life Insurance, CitiCapital, Bank One, Capmark, GE Capital, Wells Fargo and to a some extent, regional and local commercial banks. Bank of America was a major lender in the 1990s but closed its golf financing unit in the fall of 2000. There are a sufficient number of golf course lenders with ample funds to place in the market. In fact, traditional lenders and non-traditional lenders have been attracted to golf properties due to the relatively low returns in more traditional real estate investments. However, a significant number of facilities are not performing well, making it difficult for those properties to obtain mortgage financing. Only properties with well established levels of cash flow are attractive to the lender mentioned. Given the current economics for golf, financing for new projects will likely be even more difficult in the near term. Lenders in today’s market are seeking debt coverage ratios of 1.2 or higher on the trailing twelve months of net income, with loan to value ratios up to 75%. Properties without a consistent positive cash flow can expect L/V ratios of no more than 50% from most lenders. Several factors will influence the operating performance and desirability of golf facilities as investment real estate:

1. Demographics are growing for golfing population with 78 million "baby boomers" moving into prime golfing age;

2. Number of core golfers is declining while the number of occasional golfers is growing (women and youth);

3. Golf course owners and managers are becoming more sophisticated and courses are becoming more profit oriented;

The table below presents the number of facilities and courses by type every 2-years from 1996-2000 and for each year from 2000-2006, the most recent available data. It is important to note that the NGF has changed its methodology and the categorization methods in 2001. In the year 2000, the NGF tracked the par-three and executive courses and included these courses in the total supply number. Most importantly in the year 2000, the NGF changed from tracking each individual golf course to tracking facilities. A facility is defined as a complex containing at least one golf course. It is important to note that the actual supply of golf courses did not decrease, the methodology changed. In addition, in 2001, the category was only public and private, not daily fee, municipal, and private. It is important to note that from 2004 to 2005 the net number of golf courses decreased by 5 facilities, and as stated the total number of facilities decreased by 62 from 2005 to 2006.

TYPES OF GOLF COURSES 1996-2006Heritage Fields Master Plan, Irvine, California

The trend in the number of facilities is important to consider as the characteristics of supply have changed slightly. Daily fee has clearly increased as a percentage of total facilities over the eleven year study period, from 53.6% of total facilities in 1996 to 57.3% in 2006. Overall, 2004 was the peak at 16,057 facilities, with the next two years showing decreases. The daily fee class experienced the decline over the two years, whereas municipal and private facilities have actually increased. This phenomenon is consistent with the primary cause of course closures, which is real estate redevelopment. Daily fee courses are more apt to be profit oriented and cognizant of the highest and best use of the real estate, whereas private clubs owned by the membership and not as motivated by the changing real estate economics. However, 56.9% of all new courses opened in 2006 were daily fee. Industry leaders expect openings and closings to be in balance for the next few years, with no appreciable change in the number of golf facilities. During the 1990s, approximately 35 to 40 percent of all golf course development in the U.S. was a part of a residential development, and since 2000, that figure has increased to 50 to 60 percent. Additionally, of the 119.5 18-hole golf courses that opened last year, approximately sixty-nine percent were built with accompanying residential communities. The National Golf Association (NGF) also tracks the development pipeline of courses that are in planning or under construction. The chart below shows the development summary, breaking down the new, under construction and proposed golf courses as of fourth quarter 2006.

percentage and total rounds data was unavailable so the appraisers estimated the participation percentage by using the 2005 population and the total rounds by applying the CAGR to the 2005 total rounds. While total rounds are unavailable, the NGF tracks same-store rounds. Same-store rounds grew by 0.8% in 2006, after a 0.1% decline in 2005. Those gains made up for a 1.5% decline in 2003, but not for the 3.0% decline in 2002, the year most affected by 9/11. In 2006, the Gulf Coast and Southeastern U.S. had the largest gains by region, ranging from 3-5% growth. The West and Mountain regions had a negative 1% change in rounds. Most of the regional changes can be attributed to the areas of facility growth and weather issues. OUTLOOK Industry owners and operators are slightly more upbeat about the industry going into 2007. Based on surveys by NGF in late 2006, respondents are encouraged by the negative change in total courses, although local supply and demand characteristics may not reflect that change. The slight increase in rounds is also seen as a positive. Most operators realize that revenues will be flat to very mildly increasing, and that survival will depend upon controlling expenses and cash management. Issues such as weather, the stock market and the housing market are out of the operator’s control, but may have a significant impact on the profitability of each golf course. The golf industry continues to look to the future for the impending impact of the “baby boomer” generation. However, the oldest of the baby boomers are 60 and the real positive impact may be ten years away. Historically low course openings and stable rounds in the near term will allow operators to maintain their assets for the next few years. The industry is in agreement that the most important proactive strategy that golf operators can take is player development, by removing the game’s historical barriers to entry in order to attract the non-golfer to try the game, and by creating an environment that moves the occasional golfer to a core golfer. NATIONAL TRENDS CONCLUSION Overall, the national golf market continues to suffer from oversupply and relatively flat demand. Total rounds and total golfers in the U.S. remained relatively stable over the past two years. The western markets of California, Arizona, and Nevada have experienced improved conditions over the last two years. The period from 1990 to 2004 experienced continuous growth in the golf industry despite the recessionary economy the early 1990s. The decrease in new courses developed and the level of course closings are combining to bring slow improvement to the golf course market. Over the past few years, golf course development has shifted toward public daily fee use as opposed to private country club development, a trend which can be expected to continue due to the most recent federal tax laws, which reduces the deductibility of private country club memberships. All the figures presented are indicators of trends in the golf industry on a national basis. Consequently, local market conditions may differ from these national trends significantly. Some markets have experienced growth at even higher rates while others may have exhibited no growth or possibly some decline.

In summary, golf continues its popularity in the United States and there is little indication that this popularity will experience a significant decline, although minor fluctuations will occur. The demographics of the U.S. population indicate that public access golf facilities will be in strong demand for at least the next 20 years, while the national and regional economies will determine the economic success of high end daily play and private membership clubs. An overview of local market conditions is a necessary aspect of the appraisal process. The market analysis forms a basis for assessing market area boundaries, supply and demand factors, and indications of financial feasibility. We have outlined the competitive facilities below. This competitive set included both public golf courses that were chosen for their locational and economic similarities. In the communities with private courses, there is typically one public course as well. COMPETITIVE FACILITIES To determine the golf facilities which were most competitive, with the subject, we selected comparable 18 and 36 hole, daily-fee courses within Orange County, more specifically, within approximately 20 miles of the subject. To verify and support this methodology, we interviewed club managers, head professionals, and general managers at each of these selected courses to determine what other courses they competed with. The facilities found to be most competitive with the subject are summarized on the charts below. The courses have a wide range of quality and pricing. Generally the older courses have the lower rates while the new courses are priced in the upper end of the range.

AVERAGE COMPETITIVE GREEN FEESHeritage Fields Master Plan, Irvine, California

ANNUAL ROUNDS PLAYED The subject is a proposed, 27-hole, daily-fee, public golf course located at the proposed Heritage Hills master-plan in Irvine, California. We have estimated that the course will be similar to the surrounding, competitive, daily-fee courses. As presented, the annual rounds played by the competitive courses range between 80,000 and 110,000 per 18 holes. Generally, there is a connection between the overall quality of a golf course, its supporting facilities and price, and the number of rounds played. The Orange County area benefits from a year-round, mild to moderate climate, dense population, average to high household income levels, and good overall competition. Thus, the round count for courses in the market area is some of the highest in the country. CONCLUSIONS The subject is a proposed 27-hole, daily-fee, public golf course with supporting golf course facilities. It is projected to be a good quality course which is representative of the local competition with respect to length, rating, par and handicap. Additionally, we have estimated by the green fees which are in line with the market. Overall, the subject facility, as it proposed condition, will be physically similar with respect to the other daily-fee golf courses within the market. DESCRIPTION OF THE PROPOSED GOLF COURSE IMPROVEMENTS Proposed is a 306.30-acre, 27-hole, public championship golf course expected to compete with similar public, daily-fee courses within the 20 mile radius of Orange County, California. It is assumed that the fairways will have ample width, with tees and greens being build up in elevation. Also, each hole will generally will include separate tee boxes for men and women that play from three to four different distances. The yardage range for the subject should be approximately 3,200 to over 3,500 yards per nine-hole loop, varying in handicap and par. According to the development plans there will be a large driving range constructed adjacent to the golf course. The golf course irrigation system will consist of an

automatic, fully computer-monitored system. The course will feature cart paths around the tees and paths near the tees and greens. The master developer has budgeted $21,000,000 for golf course improvements and an additional $4,000,000 for clubhouse and recreational amenities. Additional costs, not directly associated with golf course construction but attributable to Park District parks and lakes total $19,600,000. PROPOSED IMPROVEMENTS AND SUPPORT FACILITIES Clubhouse: Based on the presented development plan the clubhouse will be

a permanent building that will contain approximately 25,000 square feet.

Maintenance Buildings: Permanent maintenance buildings will be constructed in

association with the golf course which are assumed to be adequate to host the maintenance operations of a high quality 27-hole daily fee operation.

Year Built: Course anticipated opening in 2009. On-Site Parking: A parking lot located adjacent to the clubhouse is proposed. Landscaping: The grounds will be attractively landscaped with trees, bushes,

shrubs, sod and underground irrigation. Personal Property (FF&E) Personal property typically included in the operation of the

subject consists of furniture, various fixtures, golf course maintenance equipment, office equipment and related items. We anticipate that these items will be owned by the golf course operation and are included in the going concern value stated.

AMERICANS WITH DISABILITIES ACT The Americans with Disabilities Act (ADA) became effective January 26, 1992. We have not made, nor are we qualified to make a compliance survey of this property to determine whether or not it is in conformity with the requirements of the ADA. It is possible that a compliance survey could reveal that the property is not in compliance with one or more of the requirements of the Act. If so, this fact could have a negative effect upon the value of the property. Since we have not been provided with the results of a survey, we did not analyze the results of possible non-compliance. HAZARDOUS SUBSTANCES We are not aware of the existence or nature of any potentially hazardous materials (such as formaldehyde foam insulation, asbestos insulation, radon gas emitting materials, or other potentially hazardous materials) which may on the property. We assume that the property is clean of any hazardous materials. However, we are not qualified to detect such materials and urge the client to employ an expert in the field to determine if such hazardous materials exist.

METHODOLOGY There are three generally accepted approaches available in developing an opinion of value: the Cost, Sales Comparison and Income Capitalization approaches. We have considered each in this appraisal to develop an opinion of the market value of the subject property. In appraisal practice, an approach to value is included or eliminated based on its applicability to the property type being valued and the quality of information available. The reliability of each approach is dependent upon the availability and comparability of the market data uncovered as well as the motivation and thinking of purchasers in the market for a property such as the subject. Each approach is discussed below, and applicability to the subject property is briefly addressed in the following summary. COST APPROACH The Cost Approach is based upon the proposition that an informed purchaser would pay no more for the subject than the cost to produce a substitute property with equivalent utility. This approach is particularly applicable when the property being appraised involves relatively new improvements which represent the highest and best use of the land; or when relatively unique or specialized improvements are located on the site, for which there exist few improved sales or leases of comparable properties. In the Cost Approach, the appraisers forms an opinion of the cost of all improvements, depreciating them to reflect any value loss from physical, functional and external causes. Land value, entrepreneurial profit and depreciated improvement costs are then added resulting in a value estimate for the subject property. SALES COMPARISON APPROACH The Sales Comparison Approach utilizes sales of comparable properties, adjusted for differences, to indicate a value for the subject property. Valuation is typically accomplished using a unit of comparison such as price per square foot of building area, effective gross income multiplier or net income multiplier. Adjustments are applied to the unit of comparison from an analysis of comparable sales, and the adjusted unit of comparison is then used to derive a value for the subject property. INCOME CAPITALIZATION APPROACH This approach first determines the income-producing capacity of a property by estimating revenue from all potential sources including dues, green fees, food and beverage and merchandise sales. Deductions then are made for operating expenses necessary to operate the golf club. The resulting net operating income is divided by an overall capitalization rate to derive an opinion of value for the subject property. The capitalization rate represents the relationship between net operating income and value. This method is referred to as Direct Capitalization. Related to the Direct Capitalization Method is the Discounted Cash Flow Method. In this method, periodic cash flows (which consist of net operating income less capital costs) and a reversionary value are developed and discounted to a present value using an internal rate of return that is determined by analyzing current investor yield requirements for similar investments. This appraisal employs the Income Capitalization Approach. Based on our analysis and knowledge of the subject property type and relevant investor profiles, it is our opinion that this approach would be

considered applicable and/or necessary for market participants. The subject's use as an amenity makes it difficult to accurately form an opinion of external obsolescence and tends to make the Cost Approach unreliable. Investors do not typically rely on the Cost Approach when purchasing a property such as the subject of this report. Therefore, we have not utilized the Cost Approach to develop an opinion of market value. The valuation process is concluded by analyzing each approach to value used in the appraisal. When more than one approach is used, each approach is judged based on its applicability, reliability, and the quantity and quality of its data. A final value opinion is chosen that either corresponds to one of the approaches to value, or is a correlation of all the approaches used in the appraisal. SALES COMPARISON APPROACH In the Sales Comparison Approach, we developed an opinion of value by comparing the subject property with similar, recently sold properties in the surrounding or competing area. Inherent in this approach is the principle of substitution, which states that when a property is replaceable in the market, its value tends to be set at the cost of acquiring an equally desirable substitute property, assuming that no costly delay is encountered in making the substitution. By analyzing sales that qualify as arm’s-length transactions between willing and knowledgeable buyers and sellers, we can identify value and price trends. The basic steps of this approach are:

1. Research recent, relevant property sales and current offerings throughout the competitive area;

2. Select and analyze properties that are similar to the property appraised, analyzing changes in economic conditions that may have occurred between the sale date and the date of value, and other physical, functional, or locational factors;

3. Identify sales that include favorable financing and calculate the cash equivalent price;

4. Reduce the sale prices to a common unit of comparison such as price per hole and net income;

5. Make appropriate comparative adjustments to the prices of the comparable properties to relate them to the property being appraised; and

6. Interpret the adjusted sales data and draw a logical value conclusion.

In this instance, the sale prices of the comparables were reduced to those common units of comparison used by purchasers, sellers, brokers and appraisers to analyze improved properties that are similar to the subject. Of the available units of comparison we have utilized the sales price per hole, which is typically used by buyers, sellers, and brokers. As discussed, golf courses are a specialty property and sales are limited due to a number of factors. There are private, member-owner courses which very rarely ever transfer, and the private, corporate, for-profit courses represent a smaller portion of the golf course pool and also turn over on a fairly limited basis. There are municipal courses owned by cities, counties, or states which also generally never sell. Finally, the daily fee courses are the more common course which sells; however, these can be due to financial duress or the owner is looking to get out of the business.

We have provided 38 national sales which include both public and private golf courses, throughout the region. We have not relied on these sales in order to conclude a price per hole, only to present them with the purpose to provide a supporting range of value, capitalization rates and NOI estimates. This can be clearly seen by the wide range in the price per hole value as well as the revenue and NOI/hole ranges. IMPROVED SALES ANALYSIS In the analysis of golf course sales, several comparative factors can be extracted. These include relationships to income that are utilized in the income approach, and relationships to physical characteristics that can be analyzed and adjusted for dissimilar qualities. The Sales Comparison Approach to value is based upon the principle of substitution. In theory, the purchaser of a property will pay no more than the cost of acquiring an equally desirable substitute property without undue delay. To estimate the degree of comparability between two golf courses, many judgment decisions are required. A search was made throughout the state of California and western U.S. market to obtain golf course sales that were comparable to the subject property. Geographically comparable sales were not found; therefore, we have utilized the most recent sales that would be considered comparable in terms of income relationships. In choosing comparable golf course or country club sales, it should be noted that unlike other real estate investments, intangible qualities contribute to the financial capabilities of a golf course. Because golf demand is an emotional and discretionary activity, demand for play at certain facilities may be based on the course architect, such as a Jack Nicklaus, Pete Dye, Donald Ross or Robert Trent Jones. This can be true on a regional level, such hosting a U.S. Open qualifier or PGA sectional event. The subject is somewhat affected by emotional characteristics such as these. It may be due to the course's items that cannot be adjusted for in a purely physical sense. They can only be measured through market acceptance in the form of revenue and net operating income. The subject will not have a name designer, but will have some characteristics that are memorable, scenic and enjoyable. However, for the most part, it is very similar to its direct competitors, and its characteristics can only be measured through an analysis of revenue and net operating income. Therefore, the sales comparison analysis for golf courses is heavily weighted to income and revenue comparisons. From the comparable sales, several potential relationships have been presented. Methods of comparison include the relationship of revenue sources to total revenue utilized in the Income Approach (Capitalization Rate); between sale price and revenue (Gross Income Multiplier or GIM); and price per hole and price per acre. The final two, while physical comparisons, are only meaningful when compared with income per hole or acre. Given the variances in physical characteristics and the difficulty in making adjustments, emphasis is placed on the income related characteristics of the property. PRICE PER HOLE The sales available represent transactions in the U.S. market that are considered to be similarly effected by economic conditions of the market. The sales range in date of sale from July 1998 to September 2006, and are considered to represent current market conditions for properties of this type. Green fees and

revenues in general have declined or remained flat in the submarket and throughout the U.S. over the past three to five years. Some courses have increased rates nominal amounts in the last year, but at levels less than their increase in expenses. Interest rates have declined, but risk has increased. Overall, the relationship of income to price is considered to have remained declined, meaning that overall capitalization rates for golf courses has declined as investors seek properties. Therefore, movement in market price is reflected in the net operating income estimate of the subject. Sales prices range from $46,111 to over $2,000,000 per hole, while the sales show a range of $5,429 to over $200,000 per hole in net operating income. Certainly the subject is not comparable to the upper end of the range; however, the revenue and income relationships are the key indicator. The subject is projected to have an NOI in Year 1 of $118,937 per hole. It is our opinion that the subject would have a price in the upper portion of the range of these sales, or about $900,000 to $1,000,000 per hole at stabilization. The value range at stabilization on a price per hole basis would be $24,300,000 to $27,000,000, say $26,000,000. Income loss prior to stabilization must then be deducted, calculated as follow:

Stabile Cash Flow $2,975,449 $2,975,449 $2,975,449Yearly Cash Flor $335,800 $1,273,306 $2,276,389

Variance $2,639,649 $1,702,143 $699,060

Total $5,040,851

INCOME LOSS PRIOR TO STABILIZATIONHeritage Fields Master Plan, Irvine, California

Thus, the value at completion, via the NOI versus price per hole method is $21,000,000 ($26,000,000 less $5,000,000). GROSS INCOME MULTIPLIER ANALYSIS: The GIM of the sales range from 0.67 to 4.52 with expense ratios ranging from 60.26% to 91.87%. The subject is expected to stabilize in Year 4 with an expense ratio of 62.2%. With an expense ratio in the lower portion of the comparable sales range, the subject GIM should be near the upper end of the range. It is our opinion that the appropriate GIM range for the subject, using a Gross Revenue of $7,861,302 is in a range of 3.00 to 3.25, shown as follows:

Gross Income Multiplier Value$7,861,302 x 3.00 = $23,583,905 Low$7,861,302 x 3.50 = $27,514,555 High

GROSS INCOME MULTIPLIER ANALYSISHeritage Fields Master Plan, Irvine, California

Based on this analysis, the stabilized market value for the subject via the GIM method is also $26,000,000. Again, deducting the income loss over the first three years of $5,000,000 rounded indicates a value at completion of $21,000,000 via the GIM method.

INCOME APPROACH The Income Capitalization Approach reflects the subject’s income-producing capabilities. This approach is based on the assumption that value is created by the expectation of benefits to be derived in the future. Specifically estimated is the amount an investor would be willing to pay to receive an income stream plus reversion value from a property over period of time. The two common valuation techniques associated with the Income Capitalization Approach are direct capitalization and the discounted cash flow (DCF) analysis. Market value of income producing real estate is typically determined by the amount of net income the property can be expected to generate over a projected investment holding period, as well as the rates of return available to potential buyers on alternative investments. An analysis of the income generating characteristics of the property and how they impact the net income available for providing a return on, and a return of, the original investment is typically considered paramount to a potential buyer. Since the Income Approach technique is that appraisal procedure and analysis which converts anticipated benefits, in terms of dollar income to be derived from the ownership of a property, into a value estimate, this procedure has been utilized as the primary analysis for purposes of this report. As discussed, the subject is a proposed, 27-hole, daily-fee golf course with proposed permanent clubhouse; therefore, we have utilized the Discounted Cash flow analysis. Given the property type and the fact that the property represents non-stabilized operations, this technique would likely be employed by a potential purchaser of the subject. ESTIMATED INCOME AND EXPENSES The next step in this approach is to estimate revenues and expenses generated by the golf course. We have itemized the revenue and expenses to include the following.

PROJECTED GOLF ROUNDS Before making other revenues and expense projections, the primary unit of comparison and analysis for golf courses is the revenue/expense per round. At a daily fee facility the number of rounds played directly relates to the largest revenue source known as greens fees. Other revenue sources have strong connection to rounds played such as cart fees, pro shop sales and driving range fees. As noted, the subject is a proposed 27-hole, daily fee golf course located within a densely populated area, with a moderate, year-round climate. We presented 18, daily-fee, golf courses within the Orange County area which is within a 20-mile radius of the proposed golf course. They range between 80,000 and 110,000 annual rounds played. Discussions with head professionals of these courses have indicated that this range is easily attainable and if they slow down they can offer specials and increase their rounds played. We have estimated that for the Year 1 of the golf course’s opening, we have estimated 60,000 annual rounds played. From here it will be expected to increase to approximately 75,000 in Year 2, 90,000 in Year 3 and stabilize in Year 4 at approximately 100,000 annual rounds played. POTENTIAL REVENUE Income sources vary depending on the type of operation such as daily fee or public course, semi-private or private. The income associated with the proposed daily-fee golf course, generally derives its income from the greens fees, driving range, as well as food and beverage revenue, and merchandise sales. We have not been provided with any proposed budgets for the golf course; therefore, the appraisers have reconstructed an operating statement for the subject based on the competitive property income and expense performances. Green Fees As noted, we have not been presented with any potential green fees for the subject. As indicated by the presented by the competitive courses within the area indicate that typical green fees a broken down between weekdays, Friday’s, weekend, twilight, or super twilight rates and all include the cart rental. Assuming the subject as proposed is within these courses based on its yardage, par, rating and handicap, we have estimated average green fees to be approximately $56.00 per round for Year 1. This fee includes the rental of a golf cart. The per round indicator will increase yearly based on inflation. Driving Range This category is related to the income derived by the use of the driving range. Based on competitive property data, we have estimated this income category to be $3.00 per round or $180,000 in Year 1. The per round indicator will increase yearly based on inflation. Food and Beverage Revenue This category includes all food and beverage sales in the clubhouse, any snack shack, the beverage cart and vending. Based on the historical performances of competitive golf courses, we have estimated this revenue to be $10.00 per round or $600,000 in Year 1. The per round indicator will increase yearly based on inflation.

Merchandise Sales This category includes the sales of all merchandise within the pro shop and ranges between golf balls, hats, shirts, clubs and bags, along with club repair and rental. Based on historical performances of competitive golf courses, we have estimated this income category to be approximately $4.00 per round or $240,000 in Year 1. We have estimated this category will increase yearly based on inflation. COST OF SALES Most clubs account for the cost of golf pro shop merchandise as a separate line item under a cost of good sold category. All items purchased for the golf shop are included in these costs. We have presented golf course expense comparables which indicates cost of goods sold for merchandise of between 65 and 79 percent. We have concluded a cost percentage of 72 percent of sales. Food and beverage sales are also included as a separate line item under a cost of goods sold category. All food and beverage costs are grouped as one general line item expense. In keeping with market standards, we have developed a formal cost of goods sold deduction for food and beverage sales. The expense comparables indicate a cost range of between 27 and 39 percent of the food and beverage sales. For the purposes of the subject, we have used a cost percentage of 40 percent of sales. EXPENSES We have relied on the historical expenses of confidential operating statements of other similar golf courses. We have separated the clubs expenses into four separate sections; Golf Operations, Course Maintenance, Food & Beverage, and Undistributed Expenses which includes Management, General & Administrative, Real Estate Taxes, Insurance, and Building Occupancy. Due to the subject being a proposed golf course with no historical information, along with no budget provided, we have relied on the previously presented expense comparables. A discussion of each expense category is described on the following pages.

C&W Year 1 Forecast Analysis

Golf Operations $600,000 Items included in this category are payroll, and payroll expenses which include the head professional, starters, and the marshalls. It also includes the repair and expenses for the maintenance of the course and includes golf course and pro shop supplies. Our estimate is based on the historical and budgeted expenses, plus expense levels at competing properties.

Course Maintenance $1,200,000 Items included in this category are payroll, and payroll expenses which include the superintendent, the assistant superintendent, the grounds crews as well as any contracted labor. It also includes all suppilies necessary for the general upkeep of the golf course. The presented expense comparables indicate a range of between 18 and 21 percent of total revenue. Due to the subject being a new course it will require a higher level of maintenence in it's first years. Therefore, we have estimated an expense of $1,200,000 or approximately 27 percent of the potential gross revenue.

Food and Beverage $300,000 This category includes all expenses for the operations of the food and beverageservice. It generally includes payroll, taxes and associates supplies. We haveestimated this cost to be approximately 50 percent of the Food and Beveragerevenue category. This amount is supported by the presented expensecomparables which indicate a range of between 35 and 65 percent.

General & AdministrativeC&W Year 1

Forecast AnalysisManagement Fee $250,000 This fee is approximately 5.5 percent of the total potential revenue figure.

General & Administrative $700,000 This category includes all dues, licensing, telephone, office supplies, bankcharges and computer support and software. This estimate is approximately 16percent of the total revenue. The expense comparables range between 7 and 17percent.

Real Estate Taxes $100,000 This category includes only the taxes associated with the golf course.

Insurance $200,000 This expense includes the liability insurance for the golf course. This estimate isapproximately 4.5 percent of the total gross revenue amount.

Building Occupancy $150,000 This category includes all utilities and maintenance of the clubhouse. It isestimated at approximately 3.4 percent of the total revenue. The expensecomparables range from 1 and 7 percent.

TOTAL EXPENSES AND NET OPERATING INCOME The Year 1 pro forma reflects total expenses, excluding reserves of $3,912,800 or approximately 89.3 percent of the potential revenue and results in a net operating income of $467,200. It should be noted that this conclusion of a high percentage of expenses and lower net operating income is not necessarily atypical for a golf course which is proposed or has been in existence for less than ten years. Often golf courses require a period of time to post positive income; it can be anywhere between 5 to 15 years, assuming they are managed professionally. This is generally due to the very high up-front capital expenditures as well as the time period in order for the course to become established. CAPITAL EXPENDITURES The subject operation includes items that require periodic replacement within the life of the property for which a reserve account should be maintained. This includes all furnishings, fixtures and equipment in the club and for course maintenance. The subject FF&E and other short lived items have been periodically replaced by ownership on a consistent basis over the last five years and the majority of FF&E appears in adequate condition.

Historical surveys for capital reserves indicate a general range from 1% to 11% with an average of 3.4%. We have also relied upon historical periodic capital replacement at competitive properties. In addition, our estimate of capital reserves going forward is estimated to be in 3% of gross revenue. DISCOUNTED CASH FLOW ANALYSIS In order to recognize the value attributable to the projected renovation, we have used the discounted cash flow analysis (DCF). Using the DCF, we are able to model the projects increases in revenue and expenses related to the renovation of the property. The Discounted Cash Flow Analysis utilizes a discounting procedure to convert future benefits to present value based upon required rates of return on investor capital and upon specific characteristics of the subject property. This method of valuation has wide acceptance among buyers and sellers of investment quality income producing property. Based upon the assumptions utilized in the Cash Flow Analysis, a resulting net cash flow was developed which includes the sale of the property at the end of the holding period, in this case five years. The value of the property is obtained by discounting the net cash flows at a discount rate which is obtained through an analysis of and review of investor requirements as published by several reliable sources. Rates to be estimated include a discount rate (cash flows) and a terminal capitalization rate (resale). The steps utilized in the Income Approach are as follows:

• Determination of the projected investment holding period and appropriate growth rate for income and expenses;

• Estimation of annual operating income and expenses during the holding period;

• Valuation analysis, and selection of capitalization method and rates;

• Conversion of projected income benefits into value.

We believe that the marketplace would want to project the performance of the property over a 5-year holding period, followed by a hypothetical sale (reversion) at the end of this term. INVESTMENT HOLDING PERIOD The first step is to project an investment holding period. In our analysis, we projected income and expenses for the subject property for a period of five years, with the reversion based on the sixth year net income. This projection is based on an analysis of market conditions for the subject property and the fact that buyers of golf properties typically base purchase decisions and investment analysis on either a 5-or 7-year time frame.

GROWTH RATES - INCOME AND EXPENSES In this analysis, we will present a discounted cash flow of the golf course using the scenario of the increase of green fees, rentals, food and beverage and tournament revenue. While we cannot be certain about future inflationary trends, we have utilized a growth rate assumption for the income categories at 3.0 percent. For expenses, we utilized a 3.0 percent growth rate for all expenses, except costs of goods sold, which was based on a fixed percentage of sales. These figures are supported by the PriceWaterhouseCoopers survey which indicates growth rates for income at 2.85% and the growth rates for expenses at 3.10%. The following table illustrates the assumptions used in the discounted cash flow analysis followed by the Discounted Cash Flow Analysis summary page for the subject value via the Income Capitalization Approach.

CAPITALIZATION RATE AND DISCOUNT RATE SUPPORT The selection of these rates has been supported by three main sources. First, we have displayed the 2005 PWC Korpacz survey for the National Golf Market, which is the most recent survey available. This survey has been discontinued. Despite being a bit dated, we have included it since it was always considered a very credible source and the timeframe is still meaningful. As can be seen below, the average cap rate was 10.77 percent and the average discount rate was 13.78 percent.

KORPACZ INVESTOR SURVEY - NATIONAL GOLF MARKETHeritage Fields Master Plan, Irvine, California

* Source: PWC- Korpacz Spring, 2005 National Golf Market Investment Survey Another source of golf capitalization rates is from an internet based service named realtyrates.com. Their quarterly survey provides capitalization rates for various property types including the golf sector. As can be seen below in the first quarter of 2006 the average golf cap rate was 11.69 percent. In the second quarter of 2006 the cap rate rose to 12.02. The average 2006 golf rate was indicated to be 11.86 percent. In addition to supporting capitalization rates from investor surveys there is also a very reliable method whereby actual capitalization rates (overall rates or OARs) can be derived from transactions of golf courses. The comparable sales chart included in each of the individual golf course appraisals supplied us with overall capitalization rates when available. The chart indicated a range from a low of 7.83 percent to a high of 15.40 percent for 24 sales across the United States. The average cap rate was 10.20 percent. However, note that the most recent sales/current contracts indicate capitalization rates lower than the average in the range of 8.50% to 10.50%.

In summarizing our capitalization rate study, the average golf capitalization rate from the three sources is as follows:

Source Cap Rate AveragePWC Korpacz 10.77%

RealtyRates.com 11.86%C&W Comparable Sales 10.20%

GOLF COURSE CAP RATESHeritage Fields Master Plan, Irvine, California

It should be emphasized that the survey results reference a wide range of golf course properties that surely differ from the subject property. We believe the general golf course quality and stable cash flow characteristics of the subject are most likely at or below the type of course assumed in the three surveys highlighted above.

Another correlation that is relevant to our capitalization rate discussion is the average rates for the hospitality or lodging industry. Since both golf and hospitality have a similar going-concern component it is reasonable to compare the hospitality asset class with golf. For instance, in the RealtyRates.com survey, lodging is running about 100 basis points below golf but still well above the non-going-concern asset classes like office and retail. Similarly, in the current PWC Korpacz lodging segment, National Full-Service Hotels are averaging 8.81 percent while the National Economy lodging segment is averaging 9.83 percent. We believe this also lends further support to the golf capitalization rates utilized by C&W.

With respect to discount rates (IRRs), we have primarily relied on the PWC Korpacz surveys. Their 2005 golf survey indicated an average discount rate of 13.78 percent. Using the same going-concern correlation between golf and lodging for discount rates, their current lodging segment, and National Full-Service Hotel discount rates are averaging 11.35 percent while the National Economy lodging segment is averaging 12.50 percent. We have also considered the spread between the going-in capitalization rate and the IRR in the Korpacz Hospitality survey data, lending support for our capitalization/discount rate spread. We believe these indices lend further support to the discount rates utilized by C&W. Specifically, the subject property is an above average golf club with a good quality pro shop building and golf course that is in need of some capital expenditures. It has a history of a growing round activity and an annual cash flow that has been trending upward over the past three years. Given the strong physical and economic characteristics of the subject, we believe our terminal capitalization rate selection of 11.00 percent is reasonable and well supported by the market data included above.

MARKET VALUE “AS IS” Previously in this report the appraisers separately analyzed and valued, in current dollars, the individual planning areas and parcels intended for future land sale revenue events. The resulting “as if complete” market values for these planning areas did not take into account the additional costs of development, primarily on- and offsite land development costs, associated with the entire master development program. In this analysis, the entire property was considered as one holding. Thus, the valuation accounts for the various remaining (as of the “as is” date of value) major backbone infrastructure land development costs, common area costs, master development costs, timing for development, profit in land development, etc. for the entire development as opposed to a single planning area/parcel. Two methods of valuation to the entire property are typically considered, the sales comparison approach and the development approach. The appraisers first considered the sales comparison approach. There have been very few recent larger master-planned land sales in Orange County. One property in nearby Orange County, the former Tustin Marine Corp Air Station (Legacy Park master-plan) was negotiated for purchase by Centex Homes and Shea Homes in 2006. The total price for the 423-acre project, in a 4-phase take-down, was $236,000,000. The project is proposed for 2,105± housing units and 6.87 million square feet of commercial space. The purchase price would correlate to $558,000 per acre and/or $112,000 per proposed housing unit. Several other dated land sales were encountered in Los Angeles, Orange, Riverside and San Diego Counties that were acquired for potential master-planned development. As individual master-plans involve a unique array of planned/proposed development, it was not possible to analyze the data in an appropriate way that would render a meaningful value for the subject. Thus, a sales comparison approach to the larger property as a whole was not utilized. In this case, the development approach was deemed the appropriate method of valuation to market value “as is” as it is the most commonly applied methodology utilized by buyers and sellers of master-planned communities in their purchasing and selling decisions. DEVELOPMENT METHOD For this analysis, the appraisers utilized the yield model (discounted cash flow) of the development method. The appraisers integrated the individual market values “as if complete” of the specific neighborhoods/planning area groups into the discounted cash flow at their prospective dates of sale. A discount was then applied for the time lag between the prospective dates of sale and the date of value "as is." There are several reasons supporting the rationale for this analysis. First, it is common for developers to analyze master-plans on a neighborhood-by-neighborhood (planning area/parcel) basis. As developers typically analyze master-plans by their individual components, the appraisers concluded market values for each respective neighborhood (planning area/parcel). This valuation process allows a master developer to identify the estimated incremental value of each neighborhood (planning area/parcel) for possible sale to guest builders or for internal purposes if proceeding with their own build-out of the project. Assuming a master developer builds out all or portions of the master-plan, separate cash flows of the individual neighborhoods allow for considerations of equity partners, accounting, allocating costs, tracking profit and

internal rates of return, land and home construction loans, etc., for each respective planning area. This methodology also allows for any profit applicable to the master developer for master land development, if applicable. Lots can be delivered in a variety of conditions, from sheet graded to fully finished with all fees paid. For the purposes of this analysis, the appraisers valued all of the individual planning areas (excluding golf course) assuming a sheet graded superpad condition as currently intended by the master developer. The revenue event for the golf course represented an “at completion” but not yet stabilized condition. ABSORPTION / PROSPECTIVE DATES OF COMPLETION The date of market value "as is" was July 1, 2007. Utilizing the master development schedule the appraisers developed prospective dates of completion and sale for specific planning areas and parcels. The prospective dates represent the time period in which individual neighborhoods would be delivered and subsequently built out by merchant builders per the developer’s critical path timeline. The prospective dates of completion were formulated so as to limit intra-project competition and allow for absorption of inventory with maximum absorption without extensive overlapping and competition among similar product types. It was assumed that physical development of the project would proceed as projected, allowing for delivery of the neighborhoods as of the dates identified by the developer and/or appraisers for prospective dates of completion. The appraisers reviewed the master developer’s critical path in formulating the development timing for both revenues and costs. The developer re-confirmed that the timing in their latest plan remains fairly consistent with their expectations. The developer’s latest plan has land sale revenue events occurring through the 3rd quarter 2014 and costs through the 1st quarter 2015. As discussed in the market analysis, the appraisers considered the developer’s timing for the residential product reasonable and market supported given our estimates of absorption and capture. However, due to initial delays in development and delivery, the appraisers did move back residential land sale events scheduled for 2007 to the 1st quarter 2008. The schedule for remaining residential land sale events were similar to those presented in the latest plan, including various “rolling option” events for the higher-priced Park District planning areas. With regard to non-residential revenue events, the appraisers’ absorption and hence timing of land sale events was more conservative than those proposed in the latest plan. Given the large amount of R&D and Education space, many cash flow events were several quarters subsequent to those projected by the developer. Again, further elaboration on timing and absorption is found in the market analysis. Per the appraisers’ schedule, the final land sale event would occur in the 4th quarter 2015, or quarter 34 of the cash flow. Tables summarizing estimated land sale revenues and projected timing for planning area land sale revenue events follow.

LAND SALE REVENUES As previously detailed and summarized in the preceding table, the appraisers concluded individual market values for the subject's respective residential and commercial planning areas/parcels, and any miscellaneous revenue events. These figures were integrated into the cash flow as revenues at their respective prospective dates of sale per the master absorption schedule. The aggregate of land sale revenues from the planning area valuation was $2,201,387,672. The golf course “at completion” value was $21,500,000. Thus, total proceeds were $2,222,887,672. As a matter of reference, this figure is 4.82% below the developer’s scheduled land sale proceeds were $2,335,384,907. The figure represents the aggregate of superpad parcel values for both residential and non-residential land. Again, any changes in actual lot yield and/or land development costs would affect the indicated revenue event assumptions. REVENUE APPRECIATION The marketing and sale of the planning areas will occur over an extended term. For this reason, it would be imprudent to assume no change in underlying land values that contribute to improved property values. In the late 1980s, the residential land market was characterized by rapidly appreciating values that at times exceeded 20% annually. Residential land values were observed to have substantially declined between 1990 and 1994, oftentimes exceeding a 50% decrease. During 1994, several submarkets experienced moderate increases as builders/developers appeared to be anticipating a shortage of available lots for construction. Between late 1993 and early 1995, increases of up to 20% were demonstrated in certain areas of Southern California. This trend stabilized in 1995 and into 1996. However, beginning in mid-1996 through 2005, demand for residential land ready for immediate development in desirable areas progressively increased. This situation, combined with the steadily decreasing supply of improved sites, fueled rapid price increases of residential land in most areas of Orange County. Starting in 2006 and through 2007 to-date demand substantially decreased, companion to decreasing home sales rates, home and land pricing. The majority of market participants surveyed anticipate 2007 to remain “soft” with positive movement in sales velocity, home, and land pricing sometime in 2008 or 2009. In general, the overall trend during the past two decades has been one of upward change. The observed fluctuation serves to illustrate the fact that changes in value do occur as normal economic cycles but are rarely predictable. Per historical home pricing information from Hanley Wood, price points (psf basis) for attached and detached housing in Orange County were increasing significantly into 2006 and then decreased in late 2006 and early 2007. Based on historical trends, a continuation in the rapid increase in pricing experienced from 1997-2005 would not be expected. The short-term projection is for flat pricing and/or stabilization. The long-term projections are for moderate positive growth in nearly all sectors. A general consensus, based upon interviews with builders, developer’s, and brokers active in the market, is for no major shifts in pricing in 2007 and into 2008. The majority of those interviewed suggested an anticipated recovery, and hence renewed price appreciation, in late 2008 or 2009. This anticipated trend is also presented in various published sources.

In that the master development cash flow incorporates “land” rather than “home” sale revenues, consideration must be given to the relative price trending in underlying land resulting from the assumed home trending assumptions. As exhibited in the following table, the appraisers prepared a land sale revenues trending analysis, which incorporates pertinent assumptions relative to said trending (i.e. home prices, home price trending, profit, costs, cost trending, time frame, etc.). The analysis was specifically tailored to the appraisers’ product and cost assumptions for Heritage Fields. Per the appraisers’ assumptions, the average home price (present dollars) in the for-sale residential neighborhoods was $1,120,000± or $437± per square foot. Static profit was assumed to remain constant at about 9% of sales when considering the weighting of multiple product lines ranging from 8% to 10%. Turn-key construction costs and fees (present dollars) were assumed to be approximately $210± per square foot with consideration of a weighted average of detached and attached product within the subject project. Finally, the term of land development and land sales (to merchant builders) was assumed to be 7.25 years.

LAND SALE REVENUES TRENDING ANALYSIS

Scenario 3 Scenario 4

Scenario 1 Scenario 2

Heritage Fields (El Toro MCAS)General Product & Pricing Assumptions

The two variables in each respective scenario were home and cost trending. Effective land price annual trending factors ranged from 0.80% to 6.99%, depending on the Scenario. As will be discussed further, the appraisers have assumed a cost inflation factor of 3.00%. Scenario 1 reflected an inverse revenue/cost trending situation in which cost increases were slightly higher than revenue appreciation. In this case, 2.00% revenue and 3.00% cost trending resulted in a net land trending factor of 0.80%. Scenario 2 demonstrated that the underlying land would trend similar to revenues and costs if both were assumed to be trending forward at the same rate of 3.00%.

Scenarios 3 and 4 demonstrated that if revenue trending exceeds cost trending, the implied land trending would increase at a greater rate. A combination of 4.00% home and 3.00% cost trending assumptions indicated an underlying land appreciation rate of 5.05% (Scenario 3). Finally, if assuming more aggressive price trending at 5.00%, and cost trending at 3.00%, the inflation factor for land would increase substantially, at 6.99% (Scenario 4). Finally, and perhaps most relative to estimated trending rates, are those assumptions being made by market participants in their selling and buying decisions. The majority of more recent pro formas indicate level pricing in the immediate near-term with 3.00% to 5.00% price trending starting in 2008 or 2009. Of note is that the subject’s developer integrated a 6.00% land trending factor in the business plan. Considering the foregoing, and assuming a 4.00% positive price trending for improved residential and commercial property starting in 2009, a 5.00% land trending factor was deemed reasonable (see Scenario 3). The 5.00% per annum increase was held constant in the valuation analysis commencing in 2009 and reflects an overall trend rather than potential cyclical variances in inflation rates over an extended period of time. Increases were calculated on a compounded quarterly basis. Again, it is important to recognize that the assumed revenue trending assumptions were made companion to cost trending assumptions (to follow). OTHER REVENUES CFD Reimbursements The total budget for CFD reimbursements is $215,000,000. The developer’s plan scheduled reimbursements to commence in 2007. However, confirmation with the developer suggests reimbursements will more likely commence in the 1st quarter 2008. For the cash flow, the appraisers scheduled 2007 reimbursements for the 1st quarter 2008 and additional reimbursements one quarter subsequent to those presented in the plan. Note that the $215,000,000 CFD reimbursement figure is in addition to the schedule $201,000,000 CFD proceeds for other public related improvements (see CFD City Obligation discussion below). The appraisers have assumed the budgeted CFD figures are reasonably true and correct. Golf Course Sale “At Completion” The appraisers valued the proposed golf course “at completion” and “at stabilized occupancy.” For the master cash flow, the “at completion” value of $21,500,000 was incorporated as a sale event in the 3rd quarter 2008, the projected date of completion. This golf course revenue figure, and corresponding date, reflect the golf course value “at completion” but not yet at stabilized occupancy. It was assumed that all golf course development and construction costs were incorporated into the LLC backbone infrastructure budget provided.

Interim Income Properties The master developer has secured various interim income streams from current and/or proposed tenancy in Heritage Hills. The income properties are managed and operated by LNR, a commercial property entity of Lennar. Per the plan, net income from these sources totals $13,112,010. The majority of this figure has already been recognized since Lennar acquired the property in 2005. Of the total, $5,798,811 is scheduled from the 3rd quarter 2007 through the 2nd quarter 2011, after which no additional income stream is anticipated. The revenue was allocated over the course of the cash flow per the developer’s schedule and reflects diminishing tenancy (income and expenses) as the project is redeveloped. The appraisers have assumed the reported income stream is reasonably true and correct and has not been provided nor reviewed leases and expenses relative. A summary of tenancy, income, and expense projections is retained in our file. MASTER-PLAN DEVELOPMENT COSTS The proposed master-planned community is subject to extensive on- and offsite development costs. Land development cost estimates were provided by the developer. The appraisers assumed the on- and offsite costs and reimbursements submitted by the developer were correct and reasonable for use in this analysis. The developer’s submitted pro forma is included in the Addenda. Engineering The total budget for non-CFD engineering costs is $47,618,055 of which $31,988,733 was reportedly remaining as of July 1, 2007. The appraisers have assumed the budgeted figures are reasonably true and correct. The remaining engineering cost was allocated over the course of the cash flow per the developer’s schedule. CFD Engineering The total budget for CFD-related engineering costs is $11,570,742 of which $7,772,963 was reportedly remaining as of July 1, 2007. The appraisers have assumed the budgeted figures are reasonably true and correct. The remaining CFD-related engineering cost was allocated over the course of the cash flow per the developer’s schedule. LLC Backbone Infrastructure The total budget for backbone land development infrastructure is $222,514,276 of which $202,581,280 was reportedly remaining as of July 1, 2007. The appraisers have assumed the budgeted figures are reasonably true and correct. The remaining backbone infrastructure cost was allocated over the course of the cash flow per the developer’s schedule. CFD Backbone Infrastructure The total budget for CFD-related backbone land development infrastructure is $155,968,635 of which $141,580,122 was reportedly remaining as of July 1, 2007. The appraisers have assumed the budgeted figures are reasonably true and correct. The remaining CFD-related backbone infrastructure cost was allocated over the course of the cash flow per the developer’s schedule.

Real Estate Taxes & Assessments Property taxes were calculated assuming a conservative 1.75% overall tax rate, initial purchase at the indicated land basis, and subsequent diminishing inventory (planning areas) as the sites are sold. The revised annual basis (remaining inventory) was increased 2.00% per annum per California law. Planning area revenue event totals were used to revise the diminishing basis for each assessment period due to diminishing inventory. Thus, the assessment to the master developer decreases as the planning areas/parcels are delivered and released from the assessment calculation. Redemption Price Per the budget, a negotiated redemption price payable to SunCal Communities totaled $74,000,000. The redemption price was negotiated for partnership dissolution. Per the developer, the redemption price has been paid in full. Acquisition, Closing Costs, & Predevelopment A land acquisition such as the subject would warrant extensive due diligence activity pertaining to entitlement issues, feasibility studies, professional services, etc. Acquisition and closing costs include title work, escrow charges, etc. The developer’s budget totaled $2,982,790, all of which had been expended as of July 1, 2007. However, a new acquisition would still require a budget for initial pre-acquisition due diligence and closing costs. Based on a review of cost budgets from other larger development properties an allowance of $500,000 was included in the first quarter of the cash flow. Homeless Provider Agreements The total budget for various negotiated homeless provider agreements is $30,580,000 of which $29,530,000 was reportedly remaining as of July 1, 2007. The remaining agreement costs were allocated over the course of the cash flow per the developer’s schedule. Development Agreement Fees Companion to the acquisition and disposition agreement are $200,000,000 in development agreement fees due the city. Per the developer, the entire $200,000,000 budget has been paid in full. North Irvine Traffic Mitigation Fee (NITM Fee) The total budget for a North Irvine Traffic Mitigation (NITM) Fee is $85,239,600. This fee was allocated over the course of the cash flow per the developer’s schedule. Planning The total budget for project planning expenses is $5,005,000 of which $1,661,660 was reportedly remaining as of July 1, 2007. The remaining planning-related costs were allocated over the course of the cash flow per the developer’s schedule.

Entitlements The total budget for project entitlement expenses is $5,500,000 of which $1,826,000 was reportedly remaining as of July 1, 2007. The budget was deemed reasonable and remaining entitlement-related costs were allocated over the course of the cash flow per the developer’s schedule. Financing / Holding Costs Land developers will commonly analyze property acquisitions with leveraged and/or unleveraged cash flows. In this analysis, the cash flows were prepared on an unleveraged basis and the reconciled discount rate (IRR) reflected the non-leveraged assumption. It is recognized that the developer will likely leverage the project with financing. However, as the discount rate employed reflected an unleveraged assumption the analysis correlated accordingly. General Legal The budget for legal expenses totaled $2,000,000 of which $1,000,000 was reportedly remaining as of July 1, 2007. This budget was deemed reasonable and remaining legal-related costs were allocated over the course of the cash flow per the developer’s schedule. Public Affairs (Special Projects) Developers will commonly allow a budget for public affair events, special projects, and other unforeseen expenditures relative to advancing the project accordingly. The budget for public affairs totaled $6,550,000 of which $3,630,000 was reportedly remaining as of July 1, 2007. This budget was deemed adequate and remaining special project costs were allocated over the course of the cash flow per the developer’s schedule. Income Property (Other Expenses) The master developer has secured various interim income streams from current and/or proposed tenancy in Heritage Hills. The net income previously reported as a revenue source was that “net” income after certain operating expenses relative to respective tenants. The master developer is responsible for additional interim income property operating expenses not reflected in the previous net income calculation. The budget totaled $7,006,396 of which $2,453,342 was reportedly remaining as of July 1, 2007. This figure was allocated per the developer’s schedule and reflects diminishing tenancy (income and expenses) as the project is redeveloped. A summary of tenancy, income, and expense projections is retained in our file. Caretaking Caretaking involves all expenses relative to security, project maintenance, etc. not reflected in any of the other cost categories. Caretaking expenses are often reflected as part of indirect construction and/or general conditions. The budget totaled $15,405,351 of which $12,452,415 was reportedly remaining as of July 1, 2007. The appraisers included an additional $250,000 allocated over the last four quarters in the cash flow for a total of $12,702,415. This cost was allocated over the course of the cash flow per the developer’s schedule.

Environmental Insurance Premium The total budget for an environmental insurance policy is $8,844,882 and the entire premium has reportedly been paid as of July 1, 2007 and therefore not included in the cash flow analysis. Environmental Cleanup The total budget for yet-to-be discovered adverse environmental conditions is $10,000,000. This figure is essentially a contingency above and beyond those environmental clean-up responsibilities borne by the US Navy. This cost was allocated over the first seven quarters of the cash flow per the developer’s schedule. CFD City Obligation The developer has budgeted $33,561,229 as a future payment to cover a financial obligation to the city. As part of the development and disposition agreement the city will receive $201,000,000 in CFD-related engineering and infrastructure construction for public improvements. Per the developer’s budget, and as reflected herein, CFD engineering and backbone infrastructure total $167,539,377 ($11,570,742 + $155,968,635). This figure is $33,460,623 less than the $201,000,000 obligation. Note that the budgeted figure is $100,606 higher than the correlation presented and the developer reported it was due to various calculations not clarified. The higher, more conservative, figure was utilized in the cash flow and allocated in Quarters 13-17 per the developer’s schedule. General Liability Insurance The general liability insurance budget totaled $20,152,018 of which $17,273,652 was reportedly remaining as of July 1, 2007. The appraisers included an additional $2,323,268 allocated over the last four quarters in the cash flow ($580,817 per quarter) for a total of $20,152,018. This cost was allocated over the course of the cash flow per the developer’s schedule. Land Sales Closing Costs Land sale commissions were assumed to be minimal in that the majority of residential planning area/parcel sales within master-planned communities occur between guest builders and the master developer without broker representation. The developer has budgeted .959% for land sale closing costs. Per their key assumptions overview, this figure reflects .29% for closing costs on residential land sales and 3.00% for commissions and closing costs on non-residential land sales. With the inclusion of commercial land parcels, an allowance of 1.50% of total land sale revenues (excluding golf course) was reasonable for closing costs, legal fees, and any brokerage fees, referral fees, etc. Master Marketing / HOA As is typical in master-planned communities, the appraisers assumed a cooperative marketing program would be created to provide additional marketing for the community. The developer has budgeted total master marketing expenses at 1.00% of home sales and assumed a 100% recovery via builder co-op. In this analysis, the appraisers assumed the co-op reimbursement program would fall slightly short of the net master marketing costs. An allowance of 0.50% of sale revenues, or $11,006,938 was included and allocated over the initial 10 quarters of the cash flow, reflecting a net cost to the developer after co-op reimbursements from

participating builders. Costs within this category also incorporated any homeowners’ fee subsidies required on the part of the master developer. In all likelihood, given the timing projected by the master developer, HOA costs would be minimal. Master Contingency The developer has included a master contingency at 20% of LLC backbone infrastructure costs. A review of other master developer budgets indicates such contingencies are typically 10% to 20% of costs. Given the scope of the project, and the other expense/cost categories, a 20% figure was deemed reasonable and included in the cash flow companion to the LLC backbone infrastructure cost expenditures. Master Management (Overhead / General & Administration) Over the duration of the project, the master developer's staff and/or hired consultants will have to oversee all aspects of the project, including planning, entitlements, development and construction oversight, land sales, master marketing, financial reporting, etc. The subject developer included this cost at 1.00% of land sale revenues. Per a review of other master developer budgets this figure was considered slightly understated and a 1.50% of land sale revenues (excluding golf course) figure was included. The management expense was allocated over the course of the cash flow with diminishing expenditures toward the end of the development duration. Development Costs Summary As summarized in the following table, remaining master development costs totaled $763,923,469. Note these cost figures do not include builder costs of intracts and residential fees due at permit, which ere passed on to guest builders and were incorporated into the individual residential planning area/parcel analyses.

COST INFLATION The development of the project will occur over an extended term. For this reason, it would be imprudent to assume no change in development costs. As detailed in the following table, the appraisers gathered historical cost information from two sources, The Engineering News Record and Marshall Valuation Service. The Marshall cost index indicated an average annual increase of 4.89% over the past 27 years ending January 2007 with an average compounded increase of 3.16% per annum. A review of the Engineering News Record (ENR) building cost index indicated an average annual increase of 4.76% over the past 25 years ending January 2005 and an average compounded increase of 3.19% per annum.

Cost increases are also commonly tied to annual CPI increases. Over the past several years, the CPI has indicated fairly modest increases, typically 2.50%± to 3.00%±. Finally, perhaps most relative to estimated cost trending rates are those assumptions being made by market participants in their selling and buying decisions. A survey of developers and builders indicated that many are incorporating slight cost inflation trending assumptions, typically ranging from 2.00% to 4.00% as of late. Of note, the subject developer utilized a construction cost trending figure of 4.00% in the business plan. Considering the foregoing, costs for labor and materials were projected to remain flat through 2008 and increasing 3.00% per annum (compounded quarterly) commencing in 2009. DISCOUNT RATE (IRR) / IMPLIED STATIC PROFIT Finally, the appraisers considered the inclusion of profit or entrepreneurial reward for the master developer.

form of return is appropriate to the master development position. In projects of lesser risk, proven success, lower costs of development, and/or smaller in size, profit is often attributable to construction and product sales only. Many considerations were taken into account in reconciling an appropriate rate for the subject, including the risk in development, timing, stage of development, cost of funds, etc. Risk elements can vary depending upon location and product but overall the following elements are typically weighed in determining an appropriate discount rate that can range from 15% to 25% for a residential master-planned community. Elements considered are stage of entitlements, developer demand for subject product, inventory competition, number of units, type of master development program, lot and product type, duration of the development, overall range of product pricing, maturity of the submarket, lot condition, and other items. This range of discount rates is also confirmed via published data such as Korpacz and RealtyRates.com. A survey of master developers and a review of master development pro formas indicate that most participants are typically requiring non-leveraged IRR hurdle rates at 20%± in a typical master development program of moderate risk. A survey of master developer’s land development pro formas indicates across the board use of single unleveraged discount rate regardless of positive or negative cash flows. No bifurcated rates were presented in any master developer pro formas utilized in the land basis purchase pro formas. In that a large portion of the profit is realized in construction, the internal rate of return (IRR), or discount rate, applicable to the master developer’s position must reflect any remaining applicable profit to the master developer for remaining land development, management, risk, time, etc. The discount rate would also account for the time (holding period) from the date of value “as is” to the prospective dates for each of the individual neighborhoods. The subject project is a large sized master-plan and has substantial cost obligations with regard to on- and offsite improvements. However, the project is an infill reuse site within a relatively mature submarket, base entitlements and discretionary permits are secured, and there is effective demand for the land uses detailed in the land use plan. The master developer’s risk would arise primarily from the long-term holding period and installation of on- and offsite improvements over the development term. Finally, there appears to be substantial interest in the acquisition of properties such as the subject. Results of this strong demand for residential land are narrow margins and lower required returns on equity. With regard to the subject, higher risk ratings relate to the recent softening in demand and price points (stage of market cycle) and fairly high proposed price points. However, the higher pricing is indeed common for this more coastal Orange County location. Lower risk ratings relate to the infill Orange County location, wide variety of product type, and secured entitlements and development agreements. In addition, the developer is currently processing a new plan, which if approved, would result in a much higher residential yield potentially exceeding 9,000 housing units. This “upside” should be recognized in the risk (discount rate) applied. Finally, it is common for master developer’s to integrate profit participation agreements with guest builders with provide an additional revenue stream over the course of the development duration. Indeed, the appraisers did

consider master developer profit participation in the planning area cash flow analyses in estimating planning area “at completion” values. Participation revenues are not guaranteed but have been achievable in previous master-plans. In this case, profit participation revenues were not included as revenue events. However, given the potential upside from such revenues, the risk rating should be indicative (lower risk).

Master Plan Product Risk / Discount Rate Ranking

The subject represents one of very few opportunities to acquire development potential land in Orange County. The Orange County infill location, current entitlements, great upside do to re-entitlement, and potential for additional participation revenues would warrant a lower discount rate moderate risk master-plans which have been typically acquired at 20%± rates. Considering these and other factors, an unleveraged IRR at the lower end of the range would be appropriate. Accordingly, 16% to 20% unleveraged discount rates would be reasonable for the subject based on a land sales model. With this in consideration, a mid-range rate of 18% was incorporated into the cash flow. Based on analysis of similar projects and past interviews with participants in large land developments this rate was sufficient to attract investment capital, considering the risk of land development and additional reward attributable to product construction and sales. Said static rate also reflects the trending assumptions for land, product, development, and construction costs. The discounted cash flow and static presentation of the revenue and cost assumptions and relative rates of return follow.

CONCLUSION Incorporating the foregoing assumptions, the discounted cash flow indicated a total property “as is” value of $1,060,047,797. The indicated value range utilizing a range of discount rates from 16% to 20% is approximately $1.00 to $1.12 billion. Under the 18% discount rate assumption, the implied static profit was $619,715,217. Said profit would equate to 33.98% of the total costs including the indicated land basis. Note that this analysis was unleveraged. Thus, the actual return on equity, or cash-on-cash, would be higher if the investment was financed. Assuming all costs of development were financed and the land represents the equity contribution, the cash-on-cash return would be 58.46%. Assuming a developer could also secure a land acquisition loan of 50%, the cash-on-cash return would be 116.92%±. These rates of return were deemed adequate to attract capital to this type investment. It should also be recognized that a master developer might also recognize additional profit in the planning area/parcel build-outs. Based upon the comprehensive analyses presented, and subject to the limiting conditions and assumptions outlined in this report, the market value “as is” of the Heritage Fields property appraised was reconciled at $1,060,000,000 as of July 1, 2007. As a matter of reference, the only larger master-plan sale comparable warranting comparison is previously mentioned former Tustin Marine Corp Air Station (Legacy Park master-plan). The total price for the 423-acre project, in a 4-phase take-down, was $236,000,000. The project is proposed for 2,105± housing units and 6.87 million square feet of commercial space. The purchase price would correlate to $558,000 per acre and/or $112,000 per proposed housing unit. The appraised value for the subject property would correlate to $503,085 per acre and $292,414 per unit. The overall value per acre is substantiated by this land sale. Due to the great variances in intended land use, commercial, number of units, unit types, etc., the indicated value per unit is not applicable for direct comparison.
