This presentation contains “forward-looking statements,” as contemplated by the Private Securities Litigation Reform Act of 1995, in which the Company discusses factors it believes may affect its performance in the future. Forward-looking statements are all statements other than historical facts, such as statements regarding assumptions, expectations, beliefs and projections about future events or conditions. You can generally identify forward-looking statements by the appearance in such a statement of words like “anticipate,” “believe,”“continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “forecast,” “project,” “should” or “will” or other comparable words or the negative of such words. The accuracy of our assumptions, expectations, beliefs and projections depend on events or conditions that change over time and are thus susceptible to change based on actual experience, new developments and known and unknown risks. We give no assurance that the forward-looking statements will prove to be correct and does not undertake any duty to update them. Our actual future results might differ from the forward-looking statements made in this presentation for a variety of reasons, which include: our inability to successfully and timely complete our various vessel construction and conversion programs, especially our MPSV program, which involves the construction and integration of highly complex vessels and systems; unsuccessful operations of our MPSVs, which are a class of vessels that we have not previously owned or operated; the inability to successfully market our MPSVs at dayrates that we have forecasted; our inability to re-charter the Superior Achiever due to the bankruptcy proceedings involving Superior Offshore International, Inc.; further weakening of demand for our TTB services; our inability to offset the loss of TTB revenues with OSV revenue increases; our inability to effectively curtail TTB operating expenses from stacked vessels; unplanned customer suspensions; cancellations or non-renewals of vessel charters, or their failure to finalize commitments to charter vessels; loss of customers; uncollectible accounts receivable; the financial stability of our customers; industry risks; activity levels in the energy markets; changes in capital spending budgets by customers; effects of competition; fluctuations in oil and natural gas prices; variations in demand for vessel services; changes in demand for refined production products or methods of delivery; increases in operating costs; the inability to accurately predict vessel utilization levels and dayrates; changes in laws that affect our domestic or international operations; less than anticipated subseainfrastructure demand activity in the GoM and other markets; the level of fleet additions by competitors that could result in over-capacity; economic and political risks; weather related risks; the ability to attract and retain qualified marine personnel; regulatory risks; the repeal or administrative weakening of the Jones Act; our ability to successfully integrate acquisitions; our ability to maintain adequate levels of insurance; drydocking delays and cost overruns and related risks; vessel accidents; oil spills; acts of terrorism; unexpected litigation and insurance expenses; our ability to finance operations or access debt and equity markets; fluctuations in foreign currency valuations compared to the U.S. dollar; risks associated with foreign operations and the expansion thereof; adverse domestic or foreign taxconsequences; the strength of the global economy in general and the strength of the economies of the countries in which we conduct our operations in particular; that a strategic transaction involving the TTB business may not occur at all or within the expected timeframe or may occur on terms and conditions that are less favorable than expected; that the TTB business will continue to be a stable source of cash flow; the ability to maintain our reputation and promote our vessels and services and other risks described under the heading “Risk Factors” of our most recent Annual Report on Form 10-K as well as other filings the Company has made with the Securities and Exchange Commission which can be found on the Company’s website www.hornbeckoffshore.com.

5-year Trailing Average Return on Invested Capital (ROIC1)

1 Return on invested capital (ROIC) is defined as tax-affected GAAP operating income divided by average net book capital (BoY long-term debt less cash plus book equity + EoY long-term debt less cash plus book equity divided by 2). For comparison purposes, all data for the numerator has been conformed to the same definition of operating income using the effective tax rate for each period for HOS and each peer, respectively.

Each data point represents the 5-year trailing average ROIC for that respective calendar year. For example, for the year 2002, the data point represents the 5-year trailing average of the ROICs from 1998 through 2002.

Regulation G EBITDA ReconciliationThis presentation contains references to the non-GAAP financial measures of earnings (net income) before interest, income taxes, depreciation and amortization, or EBITDA, and Adjusted EBITDA. The Company views EBITDA and Adjusted EBITDA primarily as liquidity measures and, therefore, believes that the GAAP financial measure most directly comparable to such measures is cash flows provided by operating activities. Reconciliations of EBITDA and Adjusted EBITDA to cash flows provided by operating activities are provided in the table below. Management's opinion regarding the usefulness of EBITDA and the components of Adjusted EBITDA to investors and a description of the ways in which management uses such measures can be found in the Company's most recent Annual Report on Form 10-K filed with the SEC. The following data is as of 27-Aug-2008.

Year Ended December 31,

Projected cash flows provided by operating activities are based, in part, on estimated future “changes in working capital” and “changes in other, net,” that are susceptible to significant variances due to the timing at quarter-end of cash inflows and outflows, most of which are beyond the Company’s ability to control. However, any future variances in those two line items from the above forward-looking reconciliations should result in an equal and opposite adjustment to actual cash flows provided by operating activities.

“Pro Forma Run-Rate” scenario illustrates the estimated incremental operating results from the recently acquired Sea Mar Fleet, recently-delivered newbuild or rebuilt vessels and all remaining vessels, if any, that are currently under construction or conversion under the Company's MPSV program and fourth OSV newbuild program, assuming all of those vessels were placed in service as of January 1, 2008 and were working at their contracted dayrates or current market dayrates commensurate with their relative size and service capabilities. All other key assumptions related to the Company’s current operating fleet, including vessel dayrates, utilization, cash operating expenses, SG&A and income tax expense, are consistent with the Company’s current 2008 guidance.

Total interest expense, net, for the "Pro Forma Run-Rate" scenario assumes $24.4m of interest expense (without any capitalization of construction period interest) on a projected post-construction debt balanace of $550.0m, offset by $3.4m of interest income at an assumed rate of 2.25% on a projected post-construction cash balance of at least $150.0m.

Results for 2001 were impacted by a $2.0m after-tax ($0.19 per diluted share) charge on early extinguishment of debt relating to a July 2001 debt refinancing. Results for 2004 were impacted by a $14.7m after-tax ($0.75 per diluted share) charge on early extinguishment of debt relating to 91% of the November 2004 refinancing of our 10.625% Senior Notes due 2008. Results for 2005 were impacted by a $1.1m after-tax ($0.05 per diluted share) charge on early extinguishment of debt relating to the January 2005 redemption of the final 9% of our 10.625% Senior Notes due 2008.

Reflects mid-point of latest reported Company guidance and estimates for each income statement metric. Company guidance for 2008E reflects a partial-year contribution from one 60,000-barrel tank barge delivered during 2008 under the Company's TTB Newbuild Program #2. TTB segment EBITDA for 2008E is expected to be approximately 16% of the mid-point of the latest company-wide 2008E guidance range.

Rationale for 2006 Convertible Notes Offering

• Opportunistic financing allowed HOS to monetize its high stock volatility and strong credit profile

• Lowest-cost source of capital available to HOS at ~560 bps less than a fixed-rate HYD tack-on

• Lowered weighted-average fixed-rate cash coupon on company-wide debt from 6.125% to 4.1%

• Favorable interest rate arbitrage of ~350 bps versus current money market rates on invested cash

• Immediately accretive to 2007E diluted EPS

TEV/EBITDA HOS Avg Sector Avg

Rationale for 2006 HOS Common Stock Buy-Back

• HOS was trading near its historic low TEV/Forward EBITDA multiples

• HOS was trading below Oct-2005 follow-on pricing, despite a substantial increase in forward EPS guidance

• Severe multiple contraction created an opportunity to buy HOS stock at “private company” multiples

TEV / Forward EBITDA Multiples

1 HOS issued 6.1m shares of common stock at $13.00 on 31-Mar-20042 HOS issued 6.1m shares of common stock at $35.35 on 6-Oct-20053 Per Goldman Sachs equity research report dated 3-Aug-20074 HOS bought 1.8m shares of common stock at $35.26 on 13-Nov-2006

Rationale for MPSV Program Expansion• “Off-the-rack” approach rather than developing proprietary designs “from scratch”

– Same basic concept as originally envisioned in OSV#4 Phase 1, only larger in scope– Allows speed to market given current U.S. shipbuilding market conditions– Existing DP3 design was adapted by HOS to meet our customers’ objectives in the GoM

• Signed contract with reputable European shipyard for world-class DP3 MPSV– 4Q2009 delivery was earliest available slot for a DP3 vessel of this size and capability– Other worldwide shipyard order books were full with earliest deliveries in 2010-2012– Subsea DP3 vessel expertise currently resides in European shipyards– Proven “T-22” design with five recent “sister” newbuilds reportedly on multi-year charters

• Customer-driven need for additional high-end ultra-deepwater vessels– Worldwide and GoM markets are expanding and require this type of specialized equipment– More ultra-deepwater construction vessels are still needed for post-2009 market – U.S.-flagged vessels with multi-purpose DP3 capabilities will be unique in the GoM market

• Complements HOS 370 MPSV-DP2 vessels and expands GoM service-offering– Gives HOS a total of up to five high-end MPSVs with broadest array of service capabilities – Along with HOS Port, represents latest element of our “bundled service” strategy– Will be only MPSV-DP3 design to be owned by a U.S. operator in the GoM

• Subsea construction market is currently dominated by foreign vessels– HOS plans to U.S.-flag the foreign-built Merwede T-22 for certain strategic benefits– 4-year exclusive license agreement to build up to two Jones Act “sister” vessels in U.S.– Jones Act qualified vessels would have precedence over foreign-flag MPSVs in GoM

Sea Mar Fleet Acquisition• Deal Summary

– Acquired Sea Mar Fleet from affiliates of Nabors for $186m in an all-cash asset deal– Sea Mar Fleet was comprised of 10 new generation OSVs and 10 conventional OSVs– Purchased 285-ft DP2 OSV newbuild with 4Q2008 delivery for expected total cost of $34m– Agreed to manage five Mexican vessels owned by Nabors and five vessels owned by others

• Strategic Fleet Acquisition– All Sea Mar vessels are U.S.-flagged and Jones Act qualified, except one conventional OSV– Sea Mar “Super 200” OSVs are a “hybrid” (in size) between a HOS 200 and 240 class OSV– Represents 40% increase in the current HOS U.S.-flagged new generation OSV fleet– Ten conventional OSVs are considered by HOS as non-core assets and may be sold

• Complementary Culture– Sea Mar had outstanding reputation for quality and safety, similar to HOS– Professional mariners and shoreside managers and support staff had long tenure with Sea Mar– HOS was successful in retaining nearly 100% of eligible Sea Mar mariners and shoreside staff

• Customer Diversification– Two Super 200 OSVs on long-term contracts in Mexico providing well stimulation support– Two Super 200 OSVs on long-term contracts in Qatar

• Accretive Transaction– Immediately accretive to diluted EPS– Purchase price was funded with cash on-hand, which was earning interest income at 5.25%– Deal economics are expected to meet all HOS target investment parameter hurdles
