Forward-Looking StatementsCertain statements contained in this presentation constitute forward-looking statements. Such forward-looking statements are based on management's current expectations and involve known and unknown risks, uncertainties and other factors that may cause the Company’s actual results to be materially different from those expressed or implied by such forward-looking statements. Such factors include, among others, the following: general economic and business conditions, both nationally and regionally; industry capacity; demographic changes; changes in, or the failure to comply with, laws and governmental regulations; the ability to enter into managed care provider arrangements on acceptable terms; changes in Medicare and Medicaid payments or reimbursement, including those resulting from a shift from traditional reimbursement to managed care plans; liability and other claims asserted against the Company; competition, including the Company’s failure to attract patients to its hospitals; the loss of any significant customers; technological and pharmaceutical improvements that increase the cost of providing, or reduce the demand for, health care; a shortage of raw materials, a breakdown in the distribution process or other factors that may increase the Company’s cost of supplies; changes in business strategy or development plans; the ability to attract and retain qualified personnel, including physicians, nurses and other health care professionals, including the impact on the Company’s labor expenses resulting from a shortage of nurses or other health care professionals; the significant indebtedness of the Company; the availability of suitable acquisition opportunities and the length of time it takes to accomplish acquisitions; the Company's ability to integrate new businesses with its existing operations; and the availability and terms of capital to fund the expansion of the Company's business, including the acquisition of additional facilities. Certain additional risks and uncertainties are discussed in the Company’s filings with the Securities and Exchange Commission, including the Company’s annual report on Form 10-K and quarterly reports on Form 10-Q. Do not rely on any forward-looking statement, as we cannot predict or control many of the factors that ultimately may affect our ability to achieve the results estimated. We make no promise to update any forward-looking statement, whether as a result of changes in underlying factors, new information, future events or otherwise.

This document includes certain financial measures and statistics, including measures such as adjusted EBITDA, which are not calculated in accordance with Generally Accepted Accounting Principles (GAAP). Management recommends that you focus on the GAAP numbers as the best indicator of financial performance. These alternative measures are provided only as a supplement to aid in analysis of the Company.

Reconciliation between non-GAAP measures and related GAAP measures can be found in our quarterly earnings release issued on August 5, 2008.

Growth strategies and performance improvement initiatives are working

� 2.2% growth in core, same-hospital admissions� Extends recent admissions growth trends� Strongest growth in four years

� 2.2% increase in paying admissions� 0.6% increase in paying outpatient visits

� Commercial admissions declined by 1.7% (core, same-hospital)� Over 90% of commercial decline in OB admissions, which is generally de-

emphasized under TGI

� 1.9% increase in commercial admissions in eight primary TGI service lines (core, same-hospital)

� 3.2% increase in same-hospital controllable operating expense per adjusted patient day� 2.6% increase on a core, same-hospital basis

� 3.0% increase in core, same-hospital surgeries

2008 - 2009 Outlook updated only for USC sale

� California concentration reduced� USC plus four other hospital divestitures and/or lease expirations

� Encino and Tarzana sales (already in disc ops) reduces cash drain

� Broadlane investment to be monetized

� $155mm

� MOB sale of 31 buildings continues to move forward

� $750mm to $950mm in cash expected to be raised in next 18 months

� Including $650mm to $850mm in 2008

� Approx $50mm raised through 6/30/08

2009 P & L impact of actions to enhance balance sheet efficiencies (1)

� $50 million = approximate full run rate(2) reduction in EBITDA

� $80 million = approximate full year reduction of net interest expense, depreciation, and other items

� Up to $30 million = net positive future impact on pre-tax income and free cash flow

And,� $50mm in seismic requirements eliminated� $40mm annual cash flow consumption at Encino-Tarzana curtailed

(1) Tenet has not yet made a final decision on use of cash proceeds. Analysis is illustrative, for modeling purposes only.

(2) Results for 2008 are not fully impacted as $10mm to $15mm still in 2008 results

Key strategies are working

�Supporting evidence visible in:

� Admissions growth

� Commercial volume growth in TGI service lines

� Net growth of active medical staff

10

Admissions growth is accelerating

�Admissions increased by 2.2% (core, same-hospital)

� Every region up by 2.5%, or greater, with exception of Southern States Region� Florida admissions increased by 3.0%

� Philadelphia admissions increased by 5.1%

� Philadelphia’s Q3’08 growth will be reduced by pre-admission review diverting incremental patients to observation status

�While Florida and Philadelphia are not large commercial markets, their volume growth is solidly profitable

(1) 2008: assumes admissions growth of 1.5%; flat outpatient visit volumes; using 2007’s average pricing. 2009: admissions growth of 2.0%; outpatient visit growth of 1.5%; using 2008’s average pricing. Margin assumption on incremental revenues is 40%.

(2) Base line pricing increases of 4.4% for 2008. These assumptions are before discrete initiatives valued in this analysis, and include certain assumptions on adverse mix change

(3) Rate parity price increases in existing contracts and anticipated future increases.(4) Full-year impact of 2007’s ED acuity capture effort and incremental adjustments to chargemaster.(5) Inflation rate reflecting normal merit increases, union contract adjustments, supplies cost increases and other items before discrete initiatives valued in

this analysis.(6) Full year impact of cost initiatives initiated in 2007.(7) Includes impact of Sierra Providence East Medical Center (El Paso), Coastal Carolina Hospital, physician practices and other non-acute operations.(8) Various risks including volume growth, volume mix, and bad debt create at least $75 million in uncertainties for 2008 performance, hence the adjusted

EBITDA outlook range from $750 mm to $825mm. 2009 uncertainties exceed those identified for 2008. This schedule is not intended to provide a series o f spot estimates or line item guidance. Other combi nations of line item

performance could produce the same or higher, or lo wer results.
