              $500,000,000    % SENIOR SUBORDINATED NOTES DUE 2007
 
    The Senior Notes and Senior Subordinated Notes (collectively, the "Notes")
are being offered by Tenet Healthcare Corporation ("Tenet" or the "Company").
The net proceeds from the sale of the Notes offered hereby (the "Offering"),
together with borrowings under the New Credit Facility (as defined herein), will
be used to consummate the Refinancing (as defined herein) in connection with the
acquisition by the Company of OrNda Healthcorp ("OrNda"). The Offering is
contingent upon the consummation of such acquisition, the OrNda Tender Offers
(as defined herein) and the establishment of the New Credit Facility. Interest
on the Notes will be payable semi-annually on January 15 and July 15 of each
year, commencing July 15, 1997. The Senior Notes will not be redeemable by the
Company prior to maturity. The Senior Subordinated Notes will be redeemable at
the option of the Company, in whole or from time to time in part, at any time on
or after January 15, 2002 at the redemption prices set forth herein, plus
accrued and unpaid interest to the date of redemption. In addition, upon the
occurrence of a Change of Control Triggering Event (as defined herein), each
holder of Notes may require the Company to repurchase such Notes at 101% of the
principal amount thereof, plus accrued and unpaid interest to the date of
repurchase. The Company will apply to list the Senior Notes and Senior
Subordinated Notes on the New York Stock Exchange ("NYSE").
 
    The Senior Notes will be general unsecured obligations of the Company
ranking senior to all subordinated indebtedness of the Company, including the
Senior Subordinated Notes, and PARI PASSU in right of payment with all other
unsubordinated indebtedness of the Company, including borrowings under the New
Credit Facility. On a pro forma basis, as of November 30, 1996, after giving
effect to the Merger (as defined herein) and the Refinancing, approximately
$   billion in principal amount of outstanding indebtedness of Tenet will by its
terms be subordinated to the Senior Notes. The Senior Subordinated Notes will be
general unsecured obligations of the Company, subordinated in right of payment
to all existing and future Senior Debt (as defined herein) of the Company,
including the Senior Notes and borrowings under the New Credit Facility. On a
pro forma basis, as of November 30, 1996, after giving effect to the Merger and
the Refinancing, Senior Debt of the Company would have been approximately $
billion. In addition, the Notes will be effectively subordinated to all
indebtedness and other obligations of the Company's subsidiaries which, on a pro
forma basis, as of November 30, 1996, after giving effect to the Merger and the
Refinancing, would have been approximately $   billion (excluding trade payables
of $   million and intercompany indebtedness).
 
    SEE "RISK FACTORS" BEGINNING ON PAGE 11 FOR A DISCUSSION OF CERTAIN FACTORS
THAT SHOULD BE CONSIDERED BY PROSPECTIVE PURCHASERS IN EVALUATING AN INVESTMENT
IN THE NOTES.
 
 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
      EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
    SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
         PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY
             REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

psychiatric facilities. Tenet intends to continue its strategic acquisitions of
and partnerships with additional hospitals in order to expand and enhance its
integrated healthcare delivery systems. For the 12 months ended August 31, 1996,
Tenet had net operating revenues, EBITDA (as defined herein) and income from
continuing operations, adjusted to reflect acquisitions, divestitures and
related adjustments, of $5.9 billion, $1.1 billion and $226.3 million,
respectively. See "Pro Forma Financial Information."
 
    On October 16, 1996, Tenet entered into an Agreement and Plan of Merger (the
"Merger Agreement") with OrNda, pursuant to which OrNda will become a wholly
owned subsidiary of Tenet (the "Merger"). OrNda is the third largest
investor-owned provider of healthcare services in the United States, delivering
a broad range of inpatient and outpatient healthcare services to urban and
suburban communities in 15 states. At October 31, 1996, OrNda operated 49
general hospitals with a total of 9,599 licensed beds. OrNda also owns or
operates six surgery centers, numerous outpatient and specialty clinics, one
psychiatric hospital and a managed healthcare Medicaid plan (the "Medicaid HMO")
with approximately 34,000 participants. For the year ended August 31, 1996,
OrNda had net operating revenues, EBITDA and income from continuing operations,
adjusted to reflect acquisitions and related adjustments, of $2.8 billion,
$409.9 million and $106.4 million, respectively. See "Pro Forma Financial
Information."
 
    Following the Merger, the Company will operate 125 general hospitals serving
urban and rural communities in 22 states, with a total of 26,949 licensed beds,
excluding pending acquisitions. For the 12 months ended August 31, 1996, on a
pro forma combined basis, the Company's net operating revenues, EBITDA and
income from continuing operations, including the pending acquisitions of three
hospitals subject to definitive agreements (the "Pending Acquisitions"), would
have been approximately $8.7 billion, $1.6 billion and $339.7 million,
respectively. See "Pro Forma Financial Information." These pro forma combined
results do not give effect to certain cost savings that management believes may
be realized following the Merger. No assurances can be made as to the amount of
cost savings, if any, that actually will be realized.
 
    Tenet believes that the Merger represents an opportunity to acquire a
substantial portfolio of hospitals providing quality care responsive to the
current managed care environment. Many of OrNda's general hospitals are located
in geographic areas where Tenet currently operates hospitals, including southern
California and south Florida. The Merger will provide an opportunity for the
Company to coordinate the services it provides in these geographic areas with
the services provided by OrNda, which the Company believes will accelerate its
development of integrated healthcare delivery systems in these areas. The Merger
also expands the Company's operations into several new geographic areas,
including Arizona, Iowa, Massachusetts, Mississippi, Nevada, Oregon, Washington,
West Virginia and Wyoming. The Company believes it will be able to integrate
effectively the operations of OrNda based on its successful integration of the
operations of American Medical Holdings, Inc. ("AMH"), which was acquired by
Tenet in March 1995.
 
    The Company's principal executive offices are located at 3820 State Street,
Santa Barbara, California 93105, and its telephone number is (805) 563-7000.

                               BUSINESS STRATEGY
 
    The Company's strategic objective is to provide quality healthcare services
responsive to the current managed care environment. Tenet believes that
competition among healthcare providers occurs primarily at the local level.
Accordingly, the Company tailors its local strategies to address the specific
competitive characteristics of the geographic areas in which it operates,
including the number of facilities operated by Tenet, the nature and structure
of physician practices and physician groups, the extent of managed care
penetration, the number and size of competitors and the demographic
characteristics of the area. Key elements of the Company's strategy are:
 
    - to develop integrated healthcare delivery systems by coordinating the
      operations and services of the Company's facilities with other hospitals
      and ancillary care providers and through alliances with physicians and
      physician groups;
 
    - to reduce costs through enhanced operating efficiencies while improving
      the quality of care provided;
 
    - to develop and maintain its strong relationships with physicians and
      generally to foster a physician-friendly culture;
 
    - to enter into discounted fee for service arrangements, capitated contracts
      and other managed care contracts with third party payors; and
 
    - to acquire and enter into strategic partnerships with hospitals, groups of
      hospitals, other healthcare businesses, ancillary healthcare providers,
      physician practices and physician practice assets where appropriate to
      expand and enhance quality integrated healthcare delivery systems
      responsive to the current managed care environment.
 
    By providing Tenet with the opportunity to combine with a company having a
substantial portfolio of large, attractive urban and suburban hospitals known
for quality care and strong financial performance, the Merger supports a major
strategic objective of Tenet to reinforce its position as a significant provider
of healthcare services in selected geographic areas throughout the United States
and to enter new geographic areas attractive to Tenet such as Arizona and
Massachusetts. Tenet believes that the Merger will create a stronger, more
geographically diverse company that will be better able to grow through
strategic acquisitions and partnerships. The combined company will continue to
emphasize the creation of strong integrated healthcare delivery systems.

Ranking......................  The Senior Notes will be general unsecured obligations of
                               the Company ranking senior to all subordinated indebtedness
                               of the Company, including the Senior Subordinated Notes, and
                               PARI PASSU in right of payment with all other existing and
                               future unsubordinated indebtedness of the Company, including
                               the Existing Senior Notes and borrowings under the New

                               the Merger and the Refinancing, Senior Debt of the Company
                               would have been approximately $  billion. See "Historical
                               and Pro Forma Capitalization," "Related Transactions,"
                               "Description of the New Credit Facility," "Description of

                               other obligations of the Company's subsidiaries which, on a
                               pro forma basis, as of November 30, 1996, after giving
                               effect to the Merger and the Refinancing, would have been
                               approximately $  billion (excluding trade payables of $
                               million and intercompany indebtedness). See "Pro Forma
                               Financial Information." The indenture governing the Senior
                               Notes (the "Senior Note Indenture") and the indenture
                               governing the Senior Subordinated Notes (the "Senior
                               Subordinated Note Indenture" and, together with the Senior
                               Note Indenture, the "Indentures") will limit the ability of
                               subsidiaries of Tenet to incur additional indebtedness.
 
Certain Covenants............  The Indentures will contain certain covenants, including,
                               but not limited to, covenants limiting: (i) the incurrence
                               by the Company and its subsidiaries of additional
                               indebtedness; (ii) the payment of dividends on and the
                               redemption of capital stock by the Company; (iii) the
                               creation of liens securing indebtedness; (iv) restrictions
                               on the ability of subsidiaries to pay dividends; (v)
                               transactions with affiliates; and (vi) the Company's ability
                               to consolidate or merge with or into, or to transfer all or
                               substantially all of its assets to, another person. See
                               "Description of Notes--Certain Covenants."
 
Use of Proceeds..............  The net proceeds to the Company from the sale of the Notes
                               are estimated to be approximately $  billion (after
                               deducting estimated expenses and underwriting discounts and
                               commissions). The Company intends to use such net proceeds,
                               together with borrowings under the New Credit Facility, to
                               consummate the Refinancing and to pay related transaction
                               fees and expenses. See "Use of Proceeds" and "Related
                               Transactions."

                              RELATED TRANSACTIONS
 
    In connection with the consummation of the Merger, the Company anticipates
registering for issuance approximately 86 million shares of its common stock to
OrNda stockholders. In addition, Tenet intends to refinance approximately $525.0
million of OrNda's outstanding public debt securities through a tender offer to
repurchase such securities (the "OrNda Tender Offers") with a portion of the
proceeds of the Offering. Tenet also intends to refinance the existing credit
facilities of Tenet and OrNda, which at August 31, 1996 had outstanding balances
of $984.0 million and $692.2 million, respectively, with the remaining proceeds
of the Offering, together with borrowings under a new credit facility (the "New
Credit Facility") providing for aggregate commitments of up to $2.5 billion. The
refinancing transactions described above are herein collectively referred to as
the "Refinancing." The Refinancing extends the maturities of the Company's
indebtedness at favorable rates and positions the Company to take advantage of
future strategic acquisition and partnership opportunities. See "Risk
Factors--Certain Financing Considerations; Leverage" and "Historical and Pro
Forma Capitalization."
 
    The Offering is conditioned upon the consummation of the Merger, the OrNda
Tender Offers and the establishment of the New Credit Facility. See "Related
Transactions."

    The unaudited Pro Forma Financial Information does not purport to present
the financial position or results of operations of Tenet had the transactions
and events assumed therein occurred on the dates specified, nor are they
necessarily indicative of the results of operations that may be achieved in the
future.
 
    The pro forma operating results do not give effect to certain cost savings
that management believes may be realized as a result of the Merger. There can be
no assurance that such cost savings, if any, will be achieved. See "Risk
Factors--Forward Looking Statements." The pro forma operating results also do
not reflect certain non-recurring costs expected to be incurred by Tenet in
connection with the Merger.

- ------------------------------
 
(1) The ratio of earnings to fixed charges is calculated by dividing income from
    continuing operations before income taxes plus fixed charges by fixed
    charges. Fixed charges consist of interest expense, including amortization
    of financing costs, and that portion of rental expense deemed to be
    representative of the interest component of rental expense.
 
(2) EBITDA represents operating income before depreciation, amortization and
    impairment losses. While EBITDA should not be construed as a substitute for
    operating income or a better indicator of liquidity than cash flows from
    operating activities, which are determined in accordance with generally
    accepted accounting principles, it is included herein to provide additional
    information with respect to the ability of the Company to meet its future
    debt service, capital expenditure and working capital requirements. EBITDA
    is not necessarily a measure of the Company's ability to fund its cash
    needs. See the Consolidated Statements of Cash Flows of Tenet and OrNda and
    the related notes thereto included in this Prospectus. EBITDA is included
    herein because management believes that certain investors find it to be a
    useful tool for measuring the ability to service debt.
 
(3) Net of capitalized portion and of pro forma interest income.
 
(4) The ratio of pro forma combined total debt outstanding at August 31, 1996 of
    $4,856.3 million to pro forma EBITDA of $1,555.8 million for the 12 months
    ended August 31, 1996 was 3.1x.

    IN ADDITION TO THE OTHER INFORMATION CONTAINED OR INCORPORATED BY REFERENCE
IN THIS PROSPECTUS, PROSPECTIVE INVESTORS SHOULD CONSIDER CAREFULLY THE
FOLLOWING FACTORS BEFORE PURCHASING THE NOTES OFFERED HEREBY. THIS PROSPECTUS
CONTAINS, IN ADDITION TO HISTORICAL INFORMATION, "FORWARD-LOOKING STATEMENTS"
UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995 (THE "REFORM ACT").
REFERENCES HEREIN TO TENET AFTER THE MERGER SHALL BE DEEMED TO INCLUDE TENET AND
ORNDA.
 
CERTAIN FINANCING CONSIDERATIONS; LEVERAGE
 
    As of August 31, 1996, Tenet had $3.2 billion of outstanding indebtedness,
which amounted to approximately 54.0% of its total capitalization including
short-term borrowings and notes and the current portion of long-term debt, and
OrNda had $1.3 billion of outstanding indebtedness, which amounted to
approximately 66.8% of its total capitalization including short-term borrowings
and notes and the current portion of long-term debt. In connection with the
Merger, Tenet is refinancing approximately $525.0 million of OrNda's public debt
securities and the existing credit facilities of Tenet and OrNda, which at
August 31, 1996 had outstanding balances of $984.0 million and $692.2 million,
respectively. On a pro forma basis, as of August 31, 1996, after giving effect
to the Merger and the Refinancing, Tenet would have had $4.9 billion of
outstanding indebtedness, which would amount to approximately 59.3% of its total
capitalization including short-term borrowings and notes and the current portion
of long-term debt, and $3.3 billion of shareholders' equity. See "Historical and
Pro Forma Capitalization," "Related Transactions" and "Pro Forma Financial
Information."
 
    Tenet anticipates that the New Credit Facility will include covenants
limiting, among other things, borrowings by, and liens on the assets of, Tenet
and its subsidiaries, investments, the sale of all or substantially all assets
and prepayment of subordinated debt, and prohibiting the repurchase of Tenet
stock and the payment of dividends, in addition to a minimum consolidated net
worth requirement and certain coverage ratio tests. In addition, the Indentures
will include, among other things, covenants limiting the incurrence of
additional debt and liens and the payment of dividends. Tenet's failure to
comply with any of these covenants could result in an event of default under its
indebtedness including the Notes and the New Credit Facility, which in turn
could cause an event of default to occur under substantially all of Tenet's
debt. An event of default could have a material adverse effect on Tenet's
business, financial condition and results of operations. See "--Possible
Inability to Repurchase Notes Upon a Change of Control," "Description of Notes"
and "Description of the New Credit Facility."
 
    The degree to which Tenet is leveraged and the covenants described above may
adversely affect Tenet's ability to finance its future operations and could
limit its ability to pursue business opportunities that may be in the interests
of Tenet and its securityholders. In particular, changes in medical technology,
existing, proposed and future legislation, regulations and the interpretation
thereof, and the increasing importance of managed care contracts and integrated
healthcare delivery systems may require significant investment in facilities,
equipment, personnel or services. Although Tenet believes that cash generated
from operations, amounts available under the New Credit Facility and its ability
to access capital markets will be sufficient to allow it to make such
investments, there can be no assurance that Tenet will be able to obtain the
funds necessary to make such investments. Furthermore, tax-exempt or
government-owned competitors have certain financial advantages such as
endowments, charitable contributions, tax-exempt financing and exemption from
sales, property and income taxes not available to Tenet, providing them with a
potential competitive advantage in making such investments. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations of
Tenet."

<PAGE>
RISKS ASSOCIATED WITH ACQUISITION STRATEGY
 
    Tenet's ability to continue to compete successfully for managed care
contracts or to expand and enhance its integrated healthcare delivery systems
may depend upon, among other things, Tenet's ability to increase the number of
its facilities and services offered. Part of Tenet's business strategy is to
expand its facilities and services through the acquisition of hospitals, groups
of hospitals, other healthcare businesses, ancillary healthcare providers,
physician practices and physician practice assets. There can be no assurance
that suitable acquisitions can be consummated on terms favorable to Tenet or
that financing, if necessary, can be obtained for such acquisitions. See
"--Certain Financing Considerations; Leverage." Further, there is no assurance
that, as Tenet continues to acquire additional facilities and related healthcare
service providers in the geographic areas in which it currently operates, it
will not face constraints on its ability to grow from Federal and state
regulatory agencies. In addition, there can be no assurance that Tenet will be
able to operate profitably any hospitals, facilities, businesses or other assets
it may acquire, effectively integrate the operations of such acquisitions or
otherwise achieve the intended benefits of such acquisitions. While management
believes that certain cost savings may be realized following the Merger, there
can be no assurance that any such savings will actually be realized or as to the
timing thereof. See "Business-- Business Strategy."
 
COMPETITION
 
    The healthcare industry has been characterized in recent years by increased
competition for patients and staff physicians, excess capacity at general
hospitals, a shift from inpatient to outpatient treatment settings and increased
consolidation. New competitive strategies of hospitals and other healthcare
providers place increasing emphasis on the use of alternative healthcare
delivery systems (such as home health services, outpatient surgery and emergency
and diagnostic centers) that eliminate or reduce lengths of hospital stays. The
principal factors contributing to these trends are advances in medical
technology and pharmaceuticals, cost-containment efforts by managed care payors,
employers and traditional health insurers, changes in regulations and
reimbursement policies, increases in the number and type of competing healthcare
providers and changes in physician practice patterns. The revenues and operating
results of most of Tenet's hospitals are significantly affected by the
hospitals' ability to negotiate favorable contracts with managed care payors.
Tenet's future success will depend, in part, on the ability of Tenet's hospitals
to continue to attract and retain staff physicians, to enter into managed care
contracts and to organize and structure integrated healthcare delivery systems
with other healthcare providers and physician practice groups. There can be no
assurance that Tenet's hospitals will continue to be able to, on terms favorable
to Tenet, attract and retain physicians to their staffs, enter into managed care
contracts or organize and structure integrated healthcare delivery systems, for
which other healthcare companies with greater financial resources or a wider
range of services may be competing. See "Business--Competition."
 
LIMITS ON REIMBURSEMENT
 
    Tenet derives a substantial portion of its net operating revenues from
third-party payors, including the Medicare and Medicaid programs. Changes in
government reimbursement programs have resulted in limitations on, increases in,
and in some cases reduced levels of, reimbursement for healthcare services, and
additional changes are anticipated. Such changes are likely to result in further
limitations on reimbursement levels especially because, in order to reach a
balanced budget, the U.S. Congress and the President are in favor of legislating
savings under both the Medicare and Medicaid programs. In addition, private
payors, including managed care payors, increasingly are demanding discounted fee
structures or the assumption by healthcare providers of all or a portion of the
financial risk through prepaid capitation arrangements. Inpatient utilization,
average lengths of stay and occupancy rates continue to be negatively affected
by payor-required pre-admission authorization and utilization review and by
payor pressure to maximize outpatient and alternative healthcare delivery
services for less acutely ill patients. In addition, efforts to impose reduced
allowances, greater discounts and more stringent cost controls by government and
other payors are expected to continue. Although Tenet is unable to predict the
effect these changes will have on its operations, as the number of patients
covered by managed care payors increases, significant
 
                                       12
<PAGE>
limits on the scope of services reimbursed and on reimbursement rates and fees
could have a material adverse effect on its business, financial condition and
results of operations.
 
EXTENSIVE REGULATION
 
    The healthcare industry is subject to extensive Federal, state and local
regulation relating to licensure, conduct of operations, ownership of
facilities, addition of facilities and services and prices for services. In
particular, Medicare and Medicaid antikickback, antifraud and abuse amendments
codified under Section 1128B(b) of the Social Security Act (the "Antikickback
Amendments") prohibit certain business practices and relationships that might
affect the provision and cost of healthcare services reimbursable under Medicare
and Medicaid, including the payment or receipt of remuneration for the referral
of patients whose care will be paid for by Medicare or other governmental
programs. Sanctions for violating the Antikickback Amendments include criminal
penalties and civil sanctions, including fines and possible exclusion from
government programs such as the Medicare and Medicaid programs. Pursuant to the
Medicare and Medicaid Patient and Program Protection Act of 1987, the Department
of Health and Human Services ("HHS") has issued regulations that describe some
of the conduct and business relationships permissible under the Antikickback
Amendments ("Safe Harbors"). The fact that a given business arrangement does not
fall within a Safe Harbor does not render the arrangement PER SE illegal.
Business arrangements of healthcare service providers that fail to satisfy the
applicable Safe Harbor criteria, however, risk increased scrutiny by enforcement
authorities. Because Tenet may be less willing than some of its competitors to
enter into business arrangements that do not clearly satisfy the Safe Harbors,
it could be at a competitive disadvantage in entering into certain transactions
and arrangements with physicians and other healthcare providers. See "--Certain
Legal Proceedings."
 
    The "Health Insurance Portability and Accountability Act of 1996," which
becomes effective January 1, 1997, amends, among other things, Title XI (42
U.S.C. 1301 ET SEQ.) to broaden the scope of current fraud and abuse laws to
include all health plans, whether or not they are reimbursed as a Federal
program.
 
    In addition, Section 1877 of the Social Security Act, which restricts
referrals by physicians of Medicare and other government-program patients to
providers of a broad range of designated health services with which they have
ownership or certain other financial arrangements, was amended effective January
1, 1995, to significantly broaden the scope of prohibited physician referrals
under the Medicare and Medicaid programs to providers with which they have
ownership or certain other financial arrangements (the "Self-Referral
Prohibitions"). Many states have adopted or are considering similar legislative
proposals, some of which extend beyond the Medicaid program to prohibit the
payment or receipt of remuneration for the referral of patients and physician
self-referrals regardless of the source of the payment for the care. Tenet's
participation in and development of joint ventures and other financial
relationships with physicians and others could be adversely affected by these
amendments and similar state enactments. The Company systematically reviews all
of its operations to ensure that it complies with the Social Security Act and
similar state statutes.
 
    Both Federal and state government agencies have announced heightened and
coordinated civil and criminal enforcement efforts. One pilot project, Operation
Restore Trust, is focused on investigating healthcare providers in the home
health and nursing home industries as well as on medical suppliers to these
providers in California, Florida, Texas, Illinois and New York. Tenet provides
home health and nursing home care in California, Florida and Texas.
 
    Some states require state approval for construction and expansion of
healthcare facilities, including findings of need for additional or expanded
healthcare facilities or services. Certificates of Need, which are issued by
governmental agencies with jurisdiction over healthcare facilities, are at times
required for capital expenditures exceeding a prescribed amount, changes in bed
capacity or services and certain other matters. Following a number of years of
decline, the number of states requiring Certificates of Need is once again on
the rise as state legislators once again are looking at the Certificate of Need
process as a way to contain rising healthcare costs. At November 30, 1996, Tenet
operated hospitals in 11 states, and OrNda operated hospitals in seven
additional states, that require state approval under Certificate of Need
 
                                       13
<PAGE>
programs. Tenet is unable to predict whether it will be able to obtain any
Certificates of Need in any jurisdiction where such Certificates of Need are
required.
 
    Tenet is unable to predict the future course of Federal, state and local
regulation or legislation, including Medicare and Medicaid statutes and
regulations. Further changes in the regulatory framework could have a material
adverse effect on Tenet's business, financial condition and results of
operations. See "Business--Healthcare Reform, Regulation and Licensing."
 
HEALTHCARE REFORM LEGISLATION
 
    Healthcare is one of the largest industries in the United States and
continues to attract much legislative interest and public attention. Medicare,
Medicaid, mandatory and other public and private hospital cost-containment
programs, proposals to limit healthcare spending, proposals to limit prices and
industry competitive factors are highly significant to the healthcare industry.
In addition, the healthcare industry is governed by a framework of Federal and
state laws, rules and regulations that are extremely complex and for which the
industry has the benefit of little or no regulatory or judicial interpretation.
Although Tenet believes it is in compliance in all material respects with such
laws, rules and regulations, if a determination is made that the Company was in
material violation of such laws, rules or regulations, its business, financial
condition and results of operations could be materially adversely affected.
 
    There continue to be Federal and state proposals that would, and actions
that do, impose more limitations on government and private payments to providers
such as Tenet and OrNda and proposals to increase co-payments and deductibles
from program and private patients. At the Federal level, both Congress and the
President have in the past, and are expected to in the future, propose
healthcare budgets that substantially reduce payments under the Medicare and
Medicaid programs. For example, in May 1996, both houses of Congress passed
bills that would have significantly reduced Medicare and Medicaid funding by
limiting future increases to the funding for such programs. Although President
Clinton vetoed those bills, the President's own proposals also propose to limit
or reduce increases in future Medicare and Medicaid payments.
 
    Many states have enacted or are considering enacting measures that are
designed to reduce their Medicaid expenditures and to make certain changes to
private healthcare insurance. Various states have applied, or are considering
applying, for a Federal waiver from current Medicaid regulations to allow them
to serve some of their Medicaid participants through managed care providers.
Tennessee has implemented such a revision and Texas has passed a law mandating
the state to apply for such a waiver. Louisiana also is considering wider use of
managed care for its Medicaid populations. California has created a voluntary
health insurance purchasing cooperative that seeks to make healthcare coverage
more affordable for businesses with five to 50 employees and, effective January
1, 1995, began changing the payment system for participants in its Medicaid
program in certain counties from fee-for-service arrangements to managed care
plans. Florida limits the amount by which a hospital's net revenues per
admission may be increased each year, has enacted a program creating a system of
local purchasing cooperatives and has proposed other changes that have not yet
been enacted. Florida has adopted, and other states are considering adopting,
legislation imposing a tax on revenues of hospitals to help finance or expand
those states' Medicaid systems. A number of other states are considering the
enactment of managed care initiatives designed to provide universal low-cost
coverage. These proposals also may attempt to include coverage for some people
who presently are uninsured.
 
    While Tenet anticipates that payments to hospitals will be reduced as a
result of future federal and state legislation, it is uncertain at this time
what legislation regarding healthcare reform may ultimately be enacted or
whether other changes in the administration or interpretation of governmental
healthcare programs will occur. There can be no assurance that future healthcare
legislation or other changes in the administration or interpretation of
governmental healthcare programs will not have a material adverse effect on
either Tenet's or OrNda's business, financial condition and results of
operations. A significant reduction in the amount of payments received by
hospitals under government programs such as Medicare
 
                                       14
<PAGE>
and Medicaid could have a material adverse effect on Tenet's business, financial
condition and results of operations. See "Business--Healthcare Reform,
Regulation and Licensing."
 
CERTAIN LEGAL PROCEEDINGS
 
    Tenet continues to defend a greater than normal level of litigation relating
to its subsidiaries' former psychiatric operations. The majority of the lawsuits
filed contain allegations of medical malpractice as well as allegations of fraud
and conspiracy against Tenet and certain of its subsidiaries and former
employees. Also named as defendants are numerous doctors and other healthcare
professionals. Tenet believes that the increase in litigation arose primarily
from advertisements made by certain lawyers seeking former psychiatric patients
in order to file claims against Tenet and certain of its subsidiaries. The
advertisements focused, in many instances, on Tenet's settlement of past
disputes involving the operations of its discontinued psychiatric business,
including Tenet's 1994 resolution of the Federal government's investigation and
a corresponding criminal plea agreement involving such discontinued psychiatric
business of Tenet. Among the suits filed during fiscal 1995 were two lawsuits in
Texas state court with approximately 740 individual plaintiffs at present who
purport to have been patients in certain Texas psychiatric facilities. During
fiscal 1996, 64 plaintiffs voluntarily withdrew from one of the lawsuits and
Tenet's motion to recuse the original trial judge in that lawsuit has been
granted. The cases of three of the 740 individual plaintiffs within one of the
lawsuits currently are set for trial in April 1997.
 
    During fiscal 1995 and 1996, lawsuits with approximately 210 plaintiffs at
present who purport to have been patients in certain Washington, D.C.
psychiatric facilities, containing allegations similar to those contained in the
Texas cases described above, were filed in the District of Columbia.
 
    In addition to the above, a purported class action was filed in Texas state
court in May 1995, containing allegations of fraud and conspiracy similar to
those described in the preceding paragraphs. The plaintiff purports to represent
all persons who were voluntarily admitted to one of 11 psychiatric hospitals in
Texas between January 1, 1981 and December 31, 1991, and satisfied certain other
criteria. In February 1996, this case was removed to Federal court. A motion by
the plaintiff to remand the case to Texas state court currently is pending. A
class has not been certified and Tenet believes that a class is not capable of
being certified.
 
    Tenet expects that additional lawsuits with similar allegations will be
filed. Tenet believes it has a number of defenses to each of these actions and
will defend these and any additional lawsuits vigorously. Until the lawsuits are
resolved, however, Tenet will continue to incur substantial legal expenses.
Although, based upon information currently available to it, management believes
that the amount of damages, if any, in excess of the reserves Tenet has recorded
for unusual litigation costs that may be awarded in any of the foregoing
unresolved legal proceedings cannot reasonably be estimated, management does not
believe it is likely that any such damages will have a material adverse effect
on Tenet's business, financial condition and results of operations. There can be
no assurance, however, that the ultimate liability will not exceed such
reserves, which primarily represent the estimated costs of defending the
actions.
 
    Two additional Federal class actions filed in August 1993 were consolidated
into one action pending in the U.S. District Court in the Central District of
California captioned In re: National Medical Enterprises Securities Litigation
II. These consolidated actions are on behalf of a purported class of
shareholders who purchased or sold stock of Tenet between January 14, 1993 and
August 26, 1993, and allege that each of the defendants violated Section 10(b)
of the Exchange Act. Based on these claims, plaintiffs seek compensatory
damages, injunctive relief, attorneys' fees, interest and costs. Tenet believes
it has meritorious defenses to this action and will defend this litigation
vigorously.
 
    In connection with the merger of American Medical Holdings, Inc. ("AMH," now
known as Tenet HealthSystem Holdings, Inc.) with and into a subsidiary of Tenet
in March 1995, a total of nine purported class actions were filed in both
Delaware and California. Such class actions were settled in August 1996. Under
the terms of that settlement, Tenet agreed to pay $350,000 for the plaintiffs'
attorneys fees and agreed that for a period of one year following final approval
of the settlement it will not engage in any transaction that will be dilutive to
existing shareholders without that transaction being approved by a
 
                                       15
<PAGE>
majority of its outside directors. Tenet believes the Merger with OrNda will not
be dilutive after taking into account the cost savings that management believes
may be realized following the Merger. Nevertheless, the Merger has been approved
by the required majority of Tenet's outside directors.
 
    In February 1996, OrNda's Midway Hospital Medical Center ("Midway") in Los
Angeles, California, which was acquired from Summit Health Ltd. ("Summit") in
April 1994, received an investigative subpoena from the Office of the Inspector
General of the United States Department of Health and Human Services (the
"OIG"). The subpoena states that it was issued in connection with an
investigation being conducted by the OIG concerning possible violations of
Medicare rules and regulations. OrNda has been advised that the investigation is
in connection with a civil investigation under the direction of the Civil
Division of the Department of Justice. OrNda is fully cooperating with the
government investigation. In June 1996 the government expanded this civil
investigation to arrangements between physicians and the remaining eleven
hospitals which OrNda acquired from Summit in 1994. Also, in an apparently
unrelated matter, the government has requested and OrNda has agreed to provide
similar records from a single hospital outside the group acquired from Summit in
1994. Tenet understands that OrNda and its outside counsel have held numerous
meetings with the governmental attorneys in respect of this matter and, as a
result, OrNda believes that at this time this investigation is focused primarily
on its hospitals' physician arrangements and not the hospitals' Medicare or
Medicaid billing practices. Although no proceedings have been instituted, in the
event that the OIG believes that any wrongdoing has occurred, civil and possibly
criminal proceedings could be instituted. If any such proceedings were
instituted and the outcome were unfavorable, OrNda could be subject to fines,
penalties and damages and also could be excluded from Medicare and other
government reimbursement programs. The aggregate amount of such fines, penalties
and damages and any such exclusion could have a material adverse effect on
OrNda's financial position or results of operations. The results of this
investigation and its impact, if any, cannot be predicted or estimated at this
time. Tenet understands that, based on information currently available to OrNda,
management of OrNda believes that if the investigation remains limited to
physician arrangements, remains civil in nature and, with the single exception
noted above, relates only to the practices of the hospitals of an acquired
corporation, the final outcome of this investigation will not have a material
adverse effect on OrNda's financial position or results of operations. If any of
the foregoing matters was to have a material adverse effect on OrNda, it could
also have a material adverse effect on Tenet's business, financial condition and
results of operations following the Merger. See "Business--Legal Proceedings."
 
POSSIBLE INABILITY TO REPURCHASE NOTES UPON A CHANGE OF CONTROL
 
    The New Credit Facility will prohibit Tenet from repurchasing Notes upon the
occurrence of a Change of Control Triggering Event. Any future credit agreements
or other agreements relating to indebtedness to which Tenet becomes a party may
contain similar restrictions and provisions. The indentures relating to the
Senior Notes and the Existing Senior Notes of Tenet may restrict the Company's
ability to purchase the Senior Subordinated Notes upon a Change of Control
Triggering Event. Accordingly, Tenet may not be able to satisfy its obligations
to repurchase the Notes unless Tenet is able to refinance or obtain waivers with
respect to the New Credit Facility and certain other indebtedness, including, in
the case of the Senior Subordinated Notes, the Existing Senior Notes and the
Senior Notes. There can be no assurance that Tenet will have the financial
resources to repurchase the Notes in the event of a Change of Control Triggering
Event, particularly if such Change of Control Triggering Event requires Tenet to
refinance, or results in the acceleration of, other indebtedness. See "--Certain
Financing Considerations; Leverage" and "Description of Notes--Repurchase at
Option of Holder Upon a Change of Control."
 
SUBSIDIARY OPERATIONS; SUBORDINATION
 
    Both before and after consummation of the Merger, substantially all of the
Company's operations are and will be conducted, and substantially all of the
assets of Tenet are and will be owned, by its subsidiaries. Accordingly, the
Notes effectively will be subordinated to all existing and future obligations
and other liabilities (including trade payables) of Tenet's subsidiaries. Any
right of Tenet to the assets of any of its subsidiaries upon the liquidation,
reorganization or insolvency of such subsidiary (and the consequent right
 
                                       16
<PAGE>
of the holders of the Notes to participate in those assets) will be effectively
subordinated to the claims of the creditors (including trade creditors) and
preferred stockholders, if any, of such subsidiary, except to the extent Tenet
has a claim against such subsidiary as a creditor of such subsidiary. In
addition, in the event that claims of Tenet as a creditor of a subsidiary are
recognized, such claims would be subordinate to any security interest in the
assets of such subsidiary and any indebtedness of such subsidiary senior to that
held by Tenet. The ability of Tenet and its subsidiaries to incur certain
obligations is limited by certain of the restrictive covenants contained in the
New Credit Facility and in the Indentures governing the Notes. The Indentures
will limit the ability of Tenet's subsidiaries to incur additional indebtedness.
On a pro forma basis, as of November 30, 1996, after giving effect to the Merger
and the Refinancing, the outstanding indebtedness and other obligations of
Tenet's subsidiaries would have been approximately $    billion (excluding trade
payables of $    million and intercompany indebtedness).
 
    In addition, Tenet's ability to make required principal and interest
payments with respect to Tenet's indebtedness, including the Notes, depends on
the earnings of its subsidiaries and on its ability to receive funds from such
subsidiaries through dividends or other payments. Since the Notes are
obligations of Tenet only, Tenet's subsidiaries are not obligated or required to
pay any amounts due pursuant to the Notes or to make funds available therefor in
the form of dividends or advances to Tenet.
 
    Further, the subordination provisions of the Senior Subordinated Note
Indenture will provide that the Company may not pay any principal of, premium,
if any, or interest on the Senior Subordinated Notes, or defease, repurchase,
redeem or otherwise acquire or retire Senior Subordinated Notes during the
continuance of a payment default with respect to any Designated Senior Debt
(which will include all borrowings under the New Credit Facility and, after the
repayment of the New Credit Facility, any other Senior Debt permitted under the
Senior Subordinated Note Indenture the principal amount of which is $100.0
million or more and that has been designated by the Company as "Designated
Senior Debt"), other than certain payments in the form of subordinated
securities or from a defeasance trust. In addition, if any non-payment default
occurs that would permit acceleration of any Designated Senior Debt, the holders
of such Designated Senior Debt may prohibit the Company from making any payment
upon or in respect of the Senior Subordinated Notes for a period of up to 179
days. Upon any liquidation or dissolution of the Company or in a bankruptcy,
reorganization, insolvency, receivership or similar proceeding relating to the
Company, holders of Senior Debt will be entitled to receive payment in full
prior to any payment to the holders of the Senior Subordinated Notes (other than
certain payments in the form of subordinated securities or from a defeasance
trust). See "Description of Notes--Subordination of Senior Subordinated Notes."
 
NO PRIOR PUBLIC MARKET
 
    Although the Company will apply for listing of the Notes on the NYSE, the
Notes are a new issue of securities with no established trading market. The
Company has been advised by the Underwriters (as defined herein) that, following
the completion of the Offering, the Underwriters presently intend to make a
market in the Notes as permitted by applicable laws and regulations. However,
the Underwriters are under no obligation to do so and may discontinue any market
making activities at any time at the sole discretion of the Underwriters. There
can be no assurance as to the liquidity of the market that may develop for the
Notes, the ability of holders of the Notes to sell their Notes or the prices at
which holders would be able to sell their Notes. The Notes could trade at prices
that may be higher or lower than the initial offering price thereof depending on
many factors, including prevailing interest rates, the Company's operating
results and the markets for similar securities. See "Underwriting."

                              RELATED TRANSACTIONS
 
THE MERGER
 
    On October 16, 1996, Tenet, OHC Acquisition Co., a Delaware corporation and
a newly formed, wholly owned subsidiary of Tenet ("Merger Sub") and OrNda
entered into the Merger Agreement, pursuant to which, among other things, Merger
Sub will be merged with and into OrNda and OrNda will become a wholly owned
subsidiary of Tenet in a transaction to be accounted for as a pooling of
interests. As a result of the Merger, each share of common stock, par value $.01
per share, of OrNda (the "OrNda Common Stock") outstanding immediately prior to
the effective time (the "Effective Time") of the Merger (other than treasury
shares and shares held by Tenet or any subsidiary of Tenet or OrNda which will
be cancelled) will be converted into the right to receive 1.35 (the "Exchange
Ratio") shares of common stock, par value $0.075 per share, of Tenet (the "Tenet
Common Stock"), and the associated preferred stock purchase rights (the
"Rights") issued in accordance with the Rights Agreement, dated as of December
7, 1988, as amended from time to time (the "Rights Agreement"), between Tenet
and Bank of America NT&SA as successor to Bankers Trust Company. Cash will be
paid in lieu of any fractional shares of Tenet Common Stock. As of November 30,
1996, OrNda had an aggregate of approximately 64.0 million shares of common
stock outstanding on a fully diluted basis. Certain stockholders of OrNda (the
"Consenting Holders") who hold in the aggregate approximately 14.0% of OrNda's
outstanding shares have executed Stockholder Voting Agreements (the "Stockholder
Voting Agreements"), pursuant to which such stockholders have agreed to vote in
favor of the Merger Agreement and the transactions contemplated thereby and
against any proposals that would impede or delay the Merger. The shares of Tenet
Common Stock to be issued pursuant to the Merger will be registered pursuant to
a Registration Statement on Form S-4 which Tenet will file with the Commission
under the Securities Act. Tenet has also granted registration rights to the
Consenting Holders with respect to the shares of Tenet Common Stock such holders
will receive in the Merger.
 
    In addition, Tenet and OrNda have entered into stock option agreements (the
"Stock Option Agreements"), pursuant to which OrNda has granted to Tenet an
option to purchase up to approximately 19.9% of the outstanding shares of OrNda
Common Stock at a price of $29.869 per share, and Tenet has granted to OrNda an
option to purchase up to approximately 10.5% of the Tenet Common Stock (on a
fully diluted basis) at a price of $22.125 per share, each under certain
circumstances. The options are exercisable in whole or in part upon the
occurrence of certain "triggering events" relating to an acquisition of the
grantor by a third party. None of such triggering events has occurred as of the
date of this Prospectus. The options will terminate upon the consummation of the
Merger or upon termination of the Merger Agreement for certain reasons.
 
THE REFINANCING
 
    As part of the Refinancing, Tenet will commence tender offers to purchase
for cash any and all of OrNda's outstanding 12.25% Senior Subordinated Notes due
2002 (the "OrNda 12.25% Notes") and 11.375% Senior Subordinated Notes due 2004
(the "OrNda 11.375% Notes" and collectively, the "OrNda Debt Securities"). The
OrNda Debt Securities had an aggregate outstanding principal amount of
approximately $525.0 million at November 30, 1996.
 
    In connection with the OrNda Tender Offers, Tenet is soliciting consents
(the "Consent Solicitations") from the holders of the OrNda Debt Securities to
eliminate certain of the restrictive covenants in the indentures relating to
such securities, including restricted payment covenants that would limit Tenet's
access to the cash flow of OrNda following the Merger.
 
    Each of the indentures relating to the OrNda Debt Securities requires the
affirmative consent of holders of record of not less than 50% of the outstanding
principal amount of the securities issued thereunder in order to effect the
proposed amendments. The amendments will become effective upon the acceptance
for purchase and payment of the OrNda Debt Securities pursuant to the OrNda
Tender Offers. The obligation pursuant to the OrNda Tender Offers to purchase
securities of each issue properly tendered and not withdrawn is conditioned
upon, among other things, (i) the execution of a supplemental indenture with
respect to the applicable indenture providing for the proposed amendments, (ii)
the consummation of
 
                                       19
<PAGE>
the Merger and (iii) the consummation of the Offering. In addition, Tenet's
obligation to make consent payments with respect to each issue of the OrNda Debt
Securities is conditioned upon Tenet's acceptance of securities of such issue
for purchase pursuant to the applicable OrNda Tender Offer. The OrNda Tender
Offers are subject to a number of additional conditions. The OrNda Tender Offers
are expected to expire on the day subsequent to the Effective Time. Tenet
currently estimates that substantially all of the OrNda Debt Securities will be
tendered and repurchased pursuant to the OrNda Tender Offers. If a lesser
aggregate principal amount of OrNda Debt Securities is tendered pursuant to the
OrNda Tender Offers, Tenet currently intends to permit the untendered securities
to remain outstanding and reduce the application of the proceeds of the Offering
accordingly. Changes in the assumptions regarding the aggregate amount of OrNda
Debt Securities purchased pursuant to the OrNda Tender Offers are not expected
to have a significant impact on Tenet's pro forma interest expense or
consolidated indebtedness following the Merger although the Notes will be
effectively subordinated to any untendered OrNda Debt Securities with respect to
the assets of OrNda. The Offering is conditioned upon consummation of the
Merger, the OrNda Tender Offers and the establishment of the New Credit
Facility.
 
    Tenet also intends to refinance the existing credit facilities of Tenet and
OrNda, which at August 31, 1996 had outstanding balances of $984.0 million and
$692.2 million, respectively, with the remaining proceeds of the Offering,
together with borrowings under the New Credit Facility. The Refinancing extends
the maturities of the Company's indebtedness at favorable rates and positions
the Company to take advantage of future strategic acquisition and partnership
opportunities.
 
SOURCES AND USES OF FUNDS
 
    The following table sets forth the sources and uses of funds to be used to
consummate the Refinancing assuming that (i) the Notes are sold at a price to
the public equal to 100% of the principal amount thereof and (ii) all of the
OrNda Debt Securities are properly tendered and not withdrawn pursuant to the
OrNda Tender Offers. The sources and uses of funds set forth below are based
upon amounts outstanding as of August 31, 1996 and the Company's best estimate
of the results of the OrNda Tender Offers and the other assumptions described
above, which estimates and assumptions are subject to change.

                                USE OF PROCEEDS
 
    Tenet intends to use the proceeds from the Offering, together with
anticipated initial borrowings of $981.8 million under the New Credit Facility,
as follows: (i) $400.0 million will be used to purchase the OrNda 12.25% Notes
pursuant to the OrNda Tender Offers (assuming 100% of the OrNda 12.25% Notes are
tendered); (ii) $125.0 million will be used to purchase the OrNda 11.375% Notes
pursuant to the OrNda Tender Offers (assuming 100% of the OrNda 11.375% Notes
are tendered); (iii) $984.0 million will be used to repay all of the outstanding
indebtedness under the existing Tenet credit facility (based upon amounts
outstanding as of August 31, 1996); (iv) $692.2 million will be used to repay
all of the outstanding indebtedness under the existing OrNda credit facility
(based upon amounts outstanding as of August 31, 1996); and (v) an estimated
$80.6 million will be applied to pay fees and expenses relating to the
Refinancing, including tender premiums and consent fees in connection with the
OrNda Tender Offers, underwriting discounts and commissions, financial advisory
fees and legal and accounting expenses. See "Related Transactions."
 
    The OrNda 12.25% Notes bear interest at 12.25% per annum and mature on May
15, 2002. The OrNda 11.375% Notes bear interest at 11.375% per annum and mature
on August 15, 2004. Borrowings under the existing Tenet credit facility bear
interest at a floating rate per annum (a weighted average rate of 6.050% at
November 30, 1996) and have a scheduled maturity of March 1, 2001. Borrowings
under the existing OrNda credit facility bear interest at a floating rate per
annum (a weighted average rate of 6.375% at November 30, 1996) and have a
scheduled maturity of October 30, 2001.

                        PRO FORMA FINANCIAL INFORMATION
 
    The following unaudited Pro Forma Financial Information is presented
assuming the Merger will be accounted for as a pooling of interests, whereby
Tenet will restate its historical consolidated financial statements to include
the assets, liabilities, shareholders' equity and results of operations of
OrNda.
 
    The statement of operations data included in the unaudited Pro Forma
Financial Information reflects the combination of the historical operating
results of Tenet for the years ended May 31, 1994 and 1995, with the historical
operating results of OrNda for the years ended August 31, 1994 and 1995 and the

historical as adjusted operating results of OrNda for the year ended August 31,
1996 and for the three months ended August 31, 1995 and 1996, respectively.
Tenet reports its financial information on the basis of a May 31 fiscal year.
OrNda reports its financial information on the basis of an August 31 fiscal
year. The Pro Forma Financial Information does not reflect the results of
operations of AMH prior to its acquisition by the Company on March 1, 1995.
 
    The unaudited Condensed Combined Pro Forma Balance Sheet gives effect to the
following transactions and events as if they had occurred as of August 31, 1996:
(i) the October 1996 acquisition by Tenet of the Lloyd Noland Hospital and the
pending acquisition by Tenet of North Shore Medical Center pursuant to the North
Shore Agreement, (ii) the September 1996 acquisition by OrNda of The Saint
Vincent Healthcare System and the pending acquisition by OrNda of the Western
Medical Centers pursuant to the United Western Agreement and (iii) the
consummation of the Merger and the Refinancing.
 
    The unaudited Pro Forma Condensed Combined Statements of Operations give
effect to the following transactions and events as if they had occurred as of
June 1, 1995 for the Tenet transactions and events and as of September 1, 1995
for the OrNda transactions and events: (i) the August 1995 acquisition by Tenet

Only material pending transactions with respect to which Tenet and OrNda have
entered into definitive agreements have been included in the unaudited Pro Forma
Financial Information.
 
    The unaudited Pro Forma Financial Information does not purport to present
the financial position or results of operations of Tenet had the transactions
and events assumed therein occurred on the dates specified, nor are they
necessarily indicative of the results of operations that may be achieved in the
future.
 
    The unaudited Pro Forma Financial Information does not give effect to
certain cost savings that Tenet management believes may be realized as a result
of the Merger. There can be no assurance that such cost savings, if any, will be
achieved. See "Risk Factors--Forward Looking Statements." The Unaudited Pro
Forma Condensed Combined Statements of Operations do not reflect certain
non-recurring costs expected to be incurred in connection with the Merger. These
costs are expected to include investment advisory fees and legal, accounting and
other professional fees and certain charges associated with the combination of
Tenet and OrNda, primarily severance costs, costs of restructuring of benefit
packages and charges related to reduction of corporate overhead costs and
consolidation of duplicative services or facilities in certain markets.
 
    The unaudited Pro Forma Financial Information is based on certain
assumptions and adjustments described in the Notes to Pro Forma Financial
Information included in this Prospectus and should be read in conjunction
therewith and with "Management's Discussion and Analysis of Financial Condition
and Results of Operations of Tenet," "Management's Discussion and Analysis of
Financial Condition and Results of Operations of OrNda" and the consolidated
financial statements of Tenet and OrNda and the related notes thereto included
herein.
 
    The Unaudited Pro Forma Condensed Combined Statements of Operations for the
years ended May 31, 1994, 1995 and 1996 combines Tenet's Consolidated Statements
of Operations for the fiscal years ended May 31, 1994, 1995 and 1996 with
OrNda's Consolidated Statements of Operations for the fiscal years ended August
31, 1994, 1995 and 1996, respectively. The Unaudited Pro Forma Condensed
Combined Statements of Operations for the three months ended August 31, 1995 and
1996 combine the Consolidated Statements of Operations of Tenet and the
Consolidated Statements of Operations of OrNda for the same three-month periods.

                    NOTES TO PRO FORMA FINANCIAL INFORMATION
 
    The adjustments to arrive at the unaudited Pro Forma Financial Information
are as follows:
 
        (a) To reflect the October 1996 acquisition by Tenet of certain assets
    and liabilities of Lloyd Noland Hospital and Tenet's pending acquisition of
    substantially all of the assets of North Shore Medical Center pursuant to
    the North Shore Agreement, both under the purchase method of accounting. The
    assets acquired and liabilities assumed in this transaction are recorded at
    their estimated fair values. The excess of the aggregate purchase price of
    $93.3 million over the aggregate estimated fair values of the net assets
    acquired is expected to be approximately $23.5 million. The acquisition of
    Lloyd Noland Hospital was financed, and the acquisition of North Shore
    Medical Center is assumed to be financed, using Tenet's existing credit
    facility.
 
        (b) To reflect the September 1996 acquisition by OrNda of The Saint
    Vincent Healthcare System and OrNda's pending acquisition of substantially
    all of the assets of the Western Medical Centers pursuant to the United
    Western Agreement, consisting primarily of two acute care hospitals and a
    skilled nursing facility. Both transactions will be accounted for by the
    purchase method of accounting. The assets acquired and liabilities assumed
    in these transactions are recorded at their estimated fair values. The
    excess of the aggregate purchase price of $188.0 million over the aggregate
    fair values of the net assets acquired is approximately $56.2 million. The
    acquisition of The Saint Vincent Healthcare System was financed, and the
    acquisition of the Western Medical Centers is assumed to be financed, using
    OrNda's existing credit facility.
 
        (c) To reclassify OrNda's current deferred tax asset to conform to
    Tenet's presentation.
 
        (d) To reflect the Refinancing and the following related items: an
    increase to intangible assets of $5.3 million (reflecting estimated debt
    issuance costs of $35.1 million to be amortized over the lives of the Notes
    and the New Credit Facility less $29.8 million in unamortized issuance costs
    to be written off); and a tax benefit of $30.1 million related to the
    payment of estimated tender premiums and consent fees and the write-off of
    the unamortized issuance costs. The $45.2 million after-tax effect of the
    write-off, the tender premiums and the consent fees will be charged to
    operations as an extraordinary item in the period the Refinancing is
    completed.
 
        (e) To record estimated transaction costs in the amount of $30.0 million
    in connection with the Merger. The unaudited Pro Forma Financial Information
    does not reflect other charges expected to be incurred by Tenet and OrNda in
    connection with the Merger. These charges may include costs associated with
    the combination of Tenet and OrNda, primarily severance costs, costs of
    restructuring benefit packages and charges related to reduction of corporate
    overhead costs and the consolidation of duplicative services or facilities
    in certain markets.
 
        (f) To reflect the historical operations of the following facilities
    prior to their acquisition by Tenet to give effect to the transactions as if
    they had occurred as of the beginning of the respective period: the August
    1995 acquisition of Memorial Medical Center (formerly known as Mercy+Baptist
    Medical Center); the September 1995 acquisition of Providence Memorial
    Hospital; the October 1995 acquisition of Medical Center of Manchester; the
    November 1995 acquisition of Methodist Hospital of Jonesboro; the June 1996
    acquisition of Hialeah Hospital; the October 1996 acquisition of Lloyd
    Noland Hospital and the pending acquisition of North Shore Medical Center
    pursuant to the North Shore Agreement.
 
        (g) To reflect the following sales by Tenet as if they had occurred as
    of the beginning of the respective period: the June 1995 sale of its two
    hospitals and related healthcare businesses in Singapore, the October 1995
    sales of its interest in AME and its equity interest in a hospital in
    Malaysia, the February 1996 sale of its equity interest in a hospital in
    Thailand and the May 1996 sale of its equity interest in Westminster.
 
        (h) To reflect the historical operations of the following facilities
    prior to their acquisition by OrNda to give effect to the transactions as if
    they had occurred as of the beginning of the respective
 
                                       30

    period: the November 1995 acquisition of Universal Medical Center
    (subsequently renamed Florida Medical Center-South); the January 1996
    acquisition of a controlling equity interest in HNW; the July 1996
    acquisitions of Cypress Fairbanks Medical Center and Westside Medical
    Center; the August 1996 acquisition of Centinela Hospital Medical Center;
    the September 1996 acquisition of The Saint Vincent Healthcare System and
    the pending acquisition by OrNda of the Western Medical Centers pursuant to
    the United Western Agreement.
 
        (i) To adjust depreciation expense to reflect the estimated fair values
    of the buildings and equipment acquired in the purchases of the general
    hospital facilities referred to in Notes (f) and (h) above.
 
        (j) To reflect the amortization of the excess of the purchase price of
    the general hospital facilities referred to in Notes (f) and (h) above over
    the estimated fair values of the net assets acquired using the straight-line
    method.
 
        (k) To reclassify OrNda's amortization of capitalized financing costs to
    interest expense in accordance with Tenet's accounting policy.
 
        (l) To reflect additional interest expense for the periods prior to the
    acquisitions described in Note (h) above ($26.3 million for the year ended
    August 31, 1996 and $4.6 million and $10.2 million for the three months
    ended August 31, 1996 and 1995, respectively) on $387.4 million of
    borrowings under OrNda's secured bank credit facility, based on an average
    historical interest rate of 7.08%.
 
       (m) To reflect additional interest expense for the periods prior to
    acquisitions described in Note (f) above ($16.8 million for the year ended
    May 31, 1996 and $1.5 million and $8.0 million for the three months ended
    August 31, 1996 and 1995, respectively) on $511.0 million of borrowings
    under Tenet's credit facilities, based on an average historical interest
    rate of 6.5%.
 
        (n) To reflect the reduction in interest expense ($13.2 million for the
    year ended May 31, 1996 and $6.1 million for the three months ended August
    31, 1995) from the application of an aggregate of $536.1 million in net
    proceeds from the sale of certain of Tenet's international assets, as
    described in Note (g) above, and the $91.8 million proceeds from Hillhaven's
    redemption of its Series C and Series D Preferred Stock held by Tenet, as
    described in Note (p) below, to repay borrowings under its credit agreements
    with an average historical interest rate of 6.5%.
 
        (o) To adjust interest expense, including the amortization of deferred
    financing costs over the term of the related indebtedness, and to reflect
    income taxes at an assumed rate of 40.0% for the year ended May 31, 1996, as
    follows (dollars in millions):

       The adjustments made for the three months ended August 31, 1995 and 1996
       are equal to one fourth of the amounts above.
 
        (p) To reflect Vencor's acquisition of Hillhaven. Because Tenet owns
    less than 20% of Vencor and does not have the ability to exercise
    significant influence over Vencor, Tenet now accounts for its interest in
    Vencor in accordance with SFAS No. 115. Tenet had accounted for its interest
    in Hillhaven
 
                                       31

    using the equity method of accounting for investments in unconsolidated
    subsidiaries. The Unaudited Pro Forma Condensed Combined Statements of
    Operations reflect adjustments made to eliminate Tenet's equity in the
    earnings of Hillhaven ($7.2 million for the year ended May 31, 1996 and $3.9
    million for the three months ended August 31, 1995) that had been recognized
    by Tenet, as well as the dividends ($1.7 million) on the Hillhaven Series C
    and Series D Preferred Stock held by Tenet prior to their September 1995
    redemption by Vencor.
 
        Also to reflect the dilution in Tenet's equity interest in TRC from an
    approximately 25% interest to an approximately 13.6% interest as a result of
    TRC's completion in October 1995 of an initial public offering of its common
    stock. Because Tenet owned less than 20% of TRC's common shares after the
    October 1995 stock sale by TRC, and does not have the ability to exercise
    significant influence over TRC, Tenet has been accounting for its investment
    in accordance with SFAS No. 115 since October 1995. Tenet's equity in the
    earnings of TRC recognized under the equity method amounted to $1.4 million
    for the year ended May 31, 1996.
 
        (q) To reflect the elimination of non-recurring gains on disposals of
    facilities and long-term investments in the amount of $346.2 million in the
    year ended May 31, 1996 and $123.5 million in the three months ended August
    31, 1995.
 
        (r) Represents the weighted average common shares and common equivalent
    shares that would have been outstanding in addition to Tenet's historical
    weighted average common shares as a result of the Merger.
 
        (s) To reflect the historical operations of Lloyd Noland Hospital prior
    to its acquisition by Tenet in October 1996 and the pending acquisition of
    North Shore Medical Center pursuant to the North Shore Agreement, giving
    effect to both transactions as if they had occurred as of the beginning of
    the period.
 
        (t) To reflect the historical operations of the following facilities
    prior to their acquisition by OrNda, giving effect to the transactions as if
    they had occurred as of the beginning of the period: the July 1996
    acquisitions of Cypress Fairbanks Medical Center and Westside Medical
    Center; the August 1996 acquisition of Centinela Hospital Medical Center;
    the September 1996 acquisition of The Saint Vincent Healthcare System and
    the pending acquisition by OrNda of the Western Medical Centers pursuant to
    the United Western Agreement.

               SELECTED HISTORICAL FINANCIAL INFORMATION OF TENET
                 TENET HEALTHCARE CORPORATION AND SUBSIDIARIES
 
    The following tables set forth selected historical financial data and other
operating information for Tenet for each of the fiscal years in the five-year
period ended May 31, 1996 and for the three months ended August 31, 1995 and
1996. The selected financial information for each of the five fiscal years has
been derived from the consolidated financial statements of Tenet, which have
been audited by KPMG Peat Marwick LLP, independent auditors for Tenet, and from
the underlying accounting records of Tenet. The report of KPMG Peat Marwick LLP
covering the consolidated financial statements of Tenet refers to a change in
the method of accounting for income taxes in 1994. The selected financial
information for the three-month periods has been derived from unaudited
condensed consolidated financial statements of Tenet and reflects all
adjustments (consisting of normal recurring adjustments) that, in the opinion of
the management of Tenet, are necessary for a fair presentation of such
information. Operating results for the three months ended August 31, 1996 are
not necessarily indicative of the results that may be expected for fiscal 1997.
 
    All information included in the following tables should be read in
conjunction with "Management's Discussion and Analysis of Financial Condition
and Results of Operations of Tenet" and with the condensed consolidated
financial statements and related notes of Tenet included herein. Certain amounts
derived from the consolidated statements of operations have been reclassified to
conform with the presentation below.

(1) Results of operations for all periods presented exclude Tenet's former
    psychiatric division which was discontinued as of November 30, 1993, but
    include, through the dates of their divestitures, other divested businesses
    that were not classified as discontinued operations.
 
(2) Results of operations for periods prior to April 1993 include, on a
    consolidated basis, the results of Westminster, the ownership of which was
    reduced from approximately 90% to 42% in April 1993 through a public
    offering of Westminster common stock.
 
(3) On March 1, 1995, Tenet acquired, in a transaction accounted for as a
    purchase, all the outstanding common stock of AMH for $1.5 billion in cash
    and 33.2 million shares of Tenet's Common Stock valued at approximately
    $488.0 million (the "AMH Merger").
 
(4) Results of operations for the periods presented include the results, through
    the respective dates of sale, of 29 inpatient rehabilitation hospitals and
    45 related satellite outpatient clinics sold in fiscal 1994, 23 long-term
    care facilities sold to Hillhaven in fiscal 1994, TRC, in which Tenet sold
    an approximately 75% interest in August 1994, two hospitals and related
    healthcare businesses in Singapore sold in June 1995, Tenet's interests in
    AME and in a hospital in Malaysia sold in October 1995, Tenet's equity
    interest in a hospital in Thailand sold in February 1996 and Tenet's equity
    interest in Westminster sold in May 1996. See Note (g) of notes to the
    unaudited Pro Forma Financial Information.
 
(5) The restructuring charges for fiscal 1992 and fiscal 1993 relate to the
    combination of Tenet's rehabilitation hospital division into its general
    hospital division, a corporate overhead reduction program begun in April
    1993 and severance costs incurred in connection with a change in senior
    executive management. The restructuring charges for fiscal 1994 relate to a
    plan initiated by Tenet in April 1994 to significantly decrease overhead
    costs by reducing corporate and division staffing levels and selling Tenet's
    corporate headquarters building in Santa Monica, California. The
    restructuring charges for fiscal 1995 relate to severance payments and
    outplacement services for involuntary terminations of former employees and
    other related costs in connection with Tenet's relocation of substantially
    all of its hospital support activities previously located in southern
    California and Florida to new offices in Dallas, Texas following the AMH
    Merger.
 
(6) The impairment losses for fiscal 1996 relate to three rehabilitation
    hospitals, four general hospitals and a parcel of undeveloped land.
 
(7) The net after-tax effect of the gains from disposals of facilities and
    long-term investments was $181.1 million or $0.84 per share, fully-diluted,
    for the year ended May 31, 1996 and $59.4 million or $0.28 per share,
    fully-diluted, for the three months ended August 31, 1995.
 
(8) The ratio of earnings to fixed charges is calculated by dividing income from
    continuing operations before income taxes plus fixed charges by fixed
    charges. Fixed charges consist of interest expense, including amortization
    of financing costs, and that portion of rental expense deemed to be
    representative of the interest component of rental expense.

IMPACT OF THE MERGER
 
    On October 16, 1996, Tenet and OrNda entered into the Merger Agreement,
pursuant to which OrNda will become a wholly owned subsidiary of Tenet in a
transaction to be accounted for as a pooling of interests. Under the terms of
the Merger Agreement, each share of OrNda Common Stock outstanding immediately
prior to the Effective Time of the Merger will be converted into the right to
receive 1.35 shares of Tenet Common Stock and the associated Rights issued in
accordance with the Rights Agreement. In connection with the consummation of the
Merger, the Company anticipates registering for issuance approximately 86.0
million shares of its common stock to OrNda stockholders. The Merger is expected
to close in the first calendar quarter of 1997.
 
    Tenet's subsidiaries operated 76 general hospitals and OrNda's subsidiaries
operated 49 general hospitals at October 31, 1996. Management believes that
joining together Tenet's general hospitals and related healthcare operations
with OrNda's general hospitals and related healthcare operations will create a
stronger, more geographically diverse company that will be better able to
compete in certain key geographic areas, such as south Florida and southern
California, and to grow through strategic acquisitions and partnerships. The
healthcare industry has undergone, and continues to undergo, tremendous change,
including cost-containment pressures by government payors, managed care
providers and others, as well as technological advances that require increased
capital expenditures. The combined company will continue to emphasize the
creation of strong integrated healthcare delivery systems. The Merger is
expected to enable the combined company to realize certain cost savings. No
assurances can be made as the amount of cost savings, if any, that actually will
be recognized.
 
    Following the Merger, the Company believes that its primary liquidity needs
will consist of capital expenditures, debt service and working capital.
Estimated capital expenditures for the combined entity are expected to be up to
approximately $[    ] million per year for each of the next three fiscal years.
The Company believes that cash generated by operations and amounts available
under the New Credit Facility will be sufficient to meet its liquidity needs
over the short term (up to 18 months) and the long term (18 months to three
years). The Company's strategy includes the pursuit of growth through strategic
acquisitions and partnerships, including the development of integrated
healthcare delivery systems in selected geographic areas. All or a portion of
such acquisitions may be financed through cash generated by operations,
available credit under the New Credit Facility or by accessing the capital
markets. At the closing of the Merger, the Company expects to have significant
unused borrowing capacity under the New Credit Facility. The New Credit Facility
and the Notes will include various affirmative, negative and financial covenants
with which the Company must comply, including among others, a requirement to
maintain certain financial ratios and limitations on the Company's ability to
incur additional indebtedness. In addition, the New Credit Facility will
prohibit dividends and stock repurchases prior to the Senior Notes being rated
investment grade by Moody's (as defined herein) or S&P (as defined herein), with
limitations on such matters thereafter.
 
RESULTS OF OPERATIONS
 
  THREE MONTHS ENDED AUGUST 31, 1996 COMPARED TO THREE MONTHS ENDED AUGUST 31,
    1995.
 
    Income before income taxes was $128.4 million in the quarter ended August
31, 1996, compared with $228.9 million in the quarter ended August 31, 1995. The
prior-year quarter includes $123.5 million in gains on sales of facilities
during the quarter, primarily the sales of the Company's interest in its
hospitals in Singapore. Excluding these gains, pre-tax income for the quarter
ended August 31, 1995 was $105.4 million.

(1) Net operating revenues of other domestic operations consist primarily of
    revenues from (i) physician practices; (ii) the Company's rehabilitation
    hospitals, long-term care facilities and psychiatric hospitals that are
    located on or near the same campuses as the Company's general hospitals;
    (iii) healthcare joint ventures operated by the Company; (iv) subsidiaries
    of the Company offering health maintenance organizations, preferred provider
    organizations and indemnity products; and (v) revenues earned by the Company
    in consideration of the guarantees of certain indebtedness and leases of
    third parties.
 
    Operating income increased by $24.7 million (or 14.2%) to $198.6 million for
the quarter ended August 31, 1996 from $173.9 million for the quarter ended
August 31, 1995. The operating margin for the current quarter increased to 13.8%
from 13.5% a year ago. The increase in the operating margin is due primarily to
effective cost-control programs in the hospitals and the continuing
implementation of overhead reduction plans.

- ------------------------------
 
*   The change is the difference between the 1995 and 1996 amounts shown.
 
    There continue to be increases in inpatient acuity and intensity as less
intensive services shift from inpatient to outpatient settings or to alternative
healthcare delivery services because of technological improvements and continued
pressures by payors to reduce admissions and lengths of stay.
 
    The Medicare program accounted for 38.2% of the net patient revenues of the
Company's domestic general hospitals for the three months ended August 31, 1996,
compared with 38.4% for the prior year quarter. Historically, rates paid under
Medicare's prospective payment system for inpatient services have increased, but
such increases have been less than cost increases. Payments for Medicare
outpatient services presently are cost reimbursed, but there are certain
proposals pending that would convert Medicare reimbursement for outpatient
services to a prospective payment system which, if implemented, may result in
reduced payments. Medicaid programs in certain states in which the Company
operates also are undergoing changes that will result in reduced payments to
hospitals.
 
    The Company has implemented hospital cost-control programs and overhead
reductions and is forming integrated healthcare delivery systems to address the
prospect of reduced payments. Pressures to control healthcare costs have
resulted in an increase in the percentage of revenues attributable to managed
care payors. The Company anticipates that its managed care business will
increase in the future.
 
    The general hospital industry in the United States and the Company's general
hospitals continue to have significant unused capacity, and thus there is
substantial competition for patients. Inpatient utilization continues to be
negatively affected by payor-required pre-admission authorization and by payor
pressure to maximize outpatient and alternative healthcare delivery services for
less acutely ill patients. Increased competition, admission constraints and
payor pressures are expected to continue. The Company's general hospitals have
been improving operating margins in a very competitive environment, due in large
part to enhanced cost controls and efficiencies being achieved throughout the
Company.
 
    Net operating revenues from the Company's other domestic operations
increased 99.6% to $149.3 million for the three months ended August 31, 1996,
compared to $74.8 million for the prior year period, representing an increase of
$74.5 million. This increase primarily reflects continued growth of physician
practices and National Health Plans, the Company's health maintenance
organization ("HMO") and insurance subsidiary.
 
    Net operating revenues from the Company's former international operations
were $33.9 million in the quarter ended August 31, 1995. During and subsequent
to that fiscal quarter, the Company sold all of its hospitals and related
healthcare businesses in Singapore and Australia.
 
    Operating expenses, which include salaries and benefits, supplies, provision
for doubtful accounts, depreciation and amortization, and other operating
expenses, were $1,240.0 million for the quarter ended August 31, 1996 and
$1,110.0 million for the prior year quarter. Operating margins for the quarters
ended August 31, 1996 and 1995 were 13.8% and 13.5%, respectively.
 
                                       38
<PAGE>
    Salaries and benefits expense as a percentage of net operating revenues was
39.5% in the quarter ended August 31, 1996 and 39.1% in the prior year quarter.
The increase is primarily due to acquisitions of physician practices.
 
    Supplies expense as a percentage of net operating revenues was 13.3% in the
quarter ended August 31, 1996 and 14.0% in the prior year quarter. The Company
has reduced supplies expense through fully incorporating acquired facilities
into the Company's group purchasing program.
 
    The provision for doubtful accounts as a percentage of net operating
revenues was 5.2% for the quarter ended August 31, 1996, and the prior year
quarter. The Company, through its collection subsidiary, Syndicated Office
Systems ("SOS"), has been establishing improved follow-up collection systems by
consolidating the collection of accounts receivable in all the Company's
facilities.
 
    Other operating expenses as a percentage of net operating revenues was 22.4%
for the quarter ended August 31, 1996 and 21.9% in the prior year quarter. The
increase is primarily attributable to acquisitions since August 31, 1995.
 
    Depreciation and amortization expense as a percentage of net operating
revenues was 5.8% in the quarter ended August 31, 1996, and 6.3% in the prior
year quarter.
 
    Interest expense, net of capitalized interest, was $71.0 million in the
quarter ended August 31, 1996 and $77.1 million in the prior year quarter. The
reduction is due to lower borrowings and interest rates in the current period.
 
    Investment earnings were $4.8 million in the quarter ended August 31, 1996,
compared with $7.3 million in the quarter ended August 31, 1995.
 
    Equity in earnings of unconsolidated affiliates was $639 thousand in the
quarter ended August 31, 1996, compared to $6.9 million in the quarter ended
August 31, 1995. The prior year quarter included $6.1 million in earnings from
two unconsolidated affiliates that were sold during fiscal 1996 and two in which
the Company's ownership interest was reduced and thus they are no longer
accounted for on the equity method of accounting. These latter two investments
are now carried in the Company's balance sheet at their fair value.
 
    Minority interests in the income of consolidated subsidiaries was $4.6
million during the quarter ended August 31, 1996, compared to $5.6 million in
the prior year quarter. The decrease is largely due to the sale of the Company's
interests in Australia during fiscal 1996.
 
    Taxes on income as a percentage of income before income taxes were 43.6% in
the August 31, 1996 quarter compared with 48.3% in the prior year quarter. The
decrease in the Company's effective income tax rate from the prior year quarter
is due primarily to gains from the sales of substantially all of the Company's
international operations in the prior year quarter.

  FISCAL YEARS ENDED MAY 31, 1996, 1995 AND 1994
 
    On March 1, 1995, in a transaction accounted for as a purchase, the Company
acquired AMH for $1.5 billion in cash and 33.2 million shares of the Company's
common stock valued at approximately $488.0 million. In connection with the AMH
Merger, the Company also repaid $1.8 billion of debt. The acquisition and debt
retirements were financed by borrowings under Tenet's then existing credit
agreement and the public issuance of $1.2 billion in new debt securities.
 
    Prior to the AMH Merger, the Company operated 33 domestic general hospitals
with 6,620 licensed beds in six states and a small number of skilled nursing
facilities, rehabilitation hospitals and psychiatric hospitals located on or
near its general hospital campuses. With the AMH Merger, the Company acquired 37
domestic general hospitals with 8,831 beds, bringing its total number of
domestic general hospitals to 70 hospitals with 15,451 licensed beds in 13
states. The acquisition also included ancillary facilities at or nearby many of
AMH's hospitals, including outpatient surgery centers, rehabilitation units,
long-term-care facilities, a psychiatric hospital, home healthcare programs and
ambulatory, occupational and rural healthcare clinics.
 
    Management believes that the AMH Merger has strengthened the Company in its
existing markets and enhanced its ability to deliver quality, cost-effective
healthcare services in new markets. The consolidation of the two companies has
resulted in certain cost savings, estimated to be at least $60.0 million in the
fiscal year ended May 31, 1996. These savings are before any severance or other
costs of implementing certain efficiencies and have been realized through (i)
the elimination of duplicate corporate overhead expenses, (ii) reduced supplies
expense through the incorporation of the acquired facilities into the Company's
existing group-purchasing program, (iii) the achievement of lower information
system costs through consolidation and outsourcing and (iv) improved collection
of the acquired AMH facilities' accounts receivable.
 
    The Company's income from continuing operations before income taxes was $746
million in 1996, compared with $329 million and $360 million in 1995 and 1994,
respectively. The most significant transactions affecting the results of
continuing operations were (i) the acquisition of AMH, (ii) the financing of the
acquisition, which added more than $250 million annually in interest expense and
(iii) a series of divestitures during fiscal 1996, 1995 and 1994.
 
    Fiscal 1996 includes the sales of the Company's interests in its hospitals
and related healthcare businesses in Singapore, Australia, Malaysia and
Thailand, its interest in Westminster, the sale of the Company's investment in
preferred stock of Hillhaven, and the exchange of its interest in the common
stock of Hillhaven for 8,301,067 shares of common stock of Vencor. Fiscal 1995
includes the sale of a 75% interest in TRC. Fiscal 1994 includes the sale of all
but six of the Company's rehabilitation hospitals and related outpatient clinics
and the sale to Hillhaven of all but seven of the Company's long-term-care
facilities, all of which had been leased to Hillhaven. These transactions and
other unusual pretax items relating to impairment losses and restructuring
charges are shown below:

- ------------------------------
 
(1) Net operating revenues of other domestic operations consist primarily of
    revenues from (i) the Company's rehabilitation hospitals, long-term care
    facilities and psychiatric hospitals which have not been divested; (ii)
    healthcare joint ventures operated by the Company; (iii) subsidiaries of the
    Company offering health maintenance organizations, preferred provider
    organizations and indemnity products; and (iv) revenues earned by the
    Company in consideration of the guarantees of certain indebtedness and
    leases of Vencor and other third parties.
 
(2) Net operating revenues of divested operations consist of revenues from (i)
    TRC prior to the August 1994 sale of the Company's approximately 75% equity
    interest; (ii) 29 rehabilitation hospitals and 45 related satellite
    outpatient clinics prior to their sales to HealthSouth Rehabilitation
    Corporation in January and March of 1994; and (iii) and lease income from
    long-term care facilities prior to their sales to Hillhaven in fiscal 1994.
 
    Net operating revenues were $5.6 billion in 1996, compared with $3.3 billion
in 1995 and $2.9 billion in 1994. The current year includes revenues
attributable to facilities acquired in the AMH Merger for the entire fiscal
year. The prior year includes three months of revenues attributable to the
facilities acquired in the AMH Merger.
 
    Operating income before impairment losses and restructuring charges
increased 81.8% to $778 million in 1996 from $428 million in 1995 and $376
million in 1994. The operating margin on this basis increased to 14.0% from
12.9% in 1995 and 12.8% in 1994. The increase in the operating margin is due
primarily to effective cost-control programs in the hospitals and the
implementation of overhead reduction plans.

- ------------------------------
 
*   The change is the difference between the 1995 and 1996 amounts shown.
 
    There continue to be increases in inpatient acuity and intensity of services
as less-intensive services shift from an inpatient to an outpatient basis or to
alternative healthcare delivery services because of technological improvements
and continued pressures by payors to reduce admissions and lengths of stay.
 
    The Company continues to experience an increase in Medicare revenues as a
percentage of total patient revenues. The Medicare program accounted for
approximately 40% of the net patient revenues of the domestic general hospitals
in 1996 and 39% and 36% in 1995 and 1994, respectively. Historically, rates paid
under Medicare's prospective payment system for inpatient services have
increased, but such increases have been less than cost increases. Payments for
Medicare outpatient services are presently cost-reimbursed, but there are
certain proposals pending that would convert Medicare reimbursement for
outpatient services to a prospective payment system which, if implemented, may
result in reduced payments. Medicaid programs in certain states in which the
Company operates also are undergoing changes that will result in reduced
payments to hospitals.
 
    The Company has implemented hospital cost-control programs and overhead
reductions and is forming integrated healthcare delivery systems to address the
reduced payments. Pressures to control healthcare costs have resulted in an
increase in the percentage of revenues attributable to managed care payors. The
percentage of the Company's net operating revenues attributable to managed care
was
 
                                       42
<PAGE>
approximately 28.6% in 1996, 26.7% in 1995, and 23.9% in 1994. The Company
anticipates that its managed care business will continue to increase in the
future.
 
    The general hospital industry in the United States and the Company's general
hospitals continue to have significant unused capacity, and thus there is
substantial competition for patients. Inpatient utilization continues to be
negatively affected by payor-required pre-admission authorization and by payor
pressure to maximize outpatient and alternative healthcare delivery services for
less acutely ill patients. Increased competition, admission constraints and
payor pressures are expected to continue. The Company's general hospitals have
been improving operating margins in a very competitive environment, due in large
part to enhanced cost controls and efficiencies being achieved throughout the
Company.
 
    Net operating revenues from the Company's other domestic operations
increased 21.0% to $375 million in 1996, compared with $310 million in 1995 and
$275 million in 1994. This increase primarily reflects continued growth of
National Health Plans, the Company's HMO and health insurance subsidiary, and
the growth of joint ventures and physician practices.
 
    The $163 million decrease in net operating revenues from the Company's
international operations for the current fiscal year compared to the prior
fiscal year is attributable to the sales of the Company's hospitals and related
healthcare businesses in Singapore and Australia. Net operating revenues and
operating profits of the sold international facilities for the period from June
1, 1995 through the dates of sales were $51 million and $7 million,
respectively.
 
    Operating expenses, which include salaries and benefits, supplies, provision
for doubtful accounts, depreciation and amortization, impairment losses,
restructuring charges and other operating expenses, were $4.9 billion in 1996,
$2.9 billion in 1995 and $2.6 billion in 1994. Operating expenses for the
current year include 12 months of operating expenses from the facilities
acquired in the AMH Merger and the prior year includes three months of operating
expenses from the facilities acquired in the AMH Merger, and to that extent, the
current and prior-year periods are not comparable. Fiscal 1995 and 1994 also
include the operating expenses of the international and other divested
operations discussed above.
 
    Salaries and benefits expense as a percentage of net operating revenues was
39.5% in 1996, 41.2% in 1995 and 43.9% in 1994. The improvement in 1996 is
attributable primarily to reductions in staffing levels in the hospitals and
corporate offices, implemented following the AMH Merger.
 
    Supplies expense as a percentage of net operating revenues was 13.7% in
1996, 13.0% in 1995 and 11.5% in 1994. The increase over the prior year is
attributable primarily to a higher supplies expense in the facilities acquired
in the AMH Merger and subsequent thereto. The increase is also attributable to
the sales of the Company's international operations. Supplies expense as a
percentage of net operating revenues at the international facilities was
substantially less than supplies expense as a percentage of net operating
revenues at the domestic general hospital operations. The Company expects to
continue to reduce supplies expense through incorporating acquired facilities
into the Company's existing group-purchasing program.
 
    The provision for doubtful accounts as a percentage of net operating
revenues was 5.2% in 1996, 4.1% in 1995 and 3.6% in 1994. The increase is
attributable primarily to higher bad debt experience at the facilities acquired
in the AMH Merger and subsequent thereto. The Company, through its collection
subsidiary, Syndicated Office Systems, has been establishing improved follow-up
collection systems by consolidating the collection of accounts receivable in all
the Company's facilities.
 
    Other operating expenses as a percentage of net operating revenues were
21.8% in 1996, 22.9% in 1995 and 22.7% in 1994. The improvement in 1996 reflects
the effects of the cost-control programs and overhead-reduction plans mentioned
herein.
 
    Depreciation and amortization expense increased from 1995 and 1994 primarily
due to the AMH Merger. Goodwill amortization associated with the AMH Merger is
approximately $64 million annually.
 
                                       43
<PAGE>
    Impairment losses representing noncash charges of $86 million were recorded
in fiscal 1996 in accordance with Statement of Financial Accounting Standards
No. 121, under which the carrying value of property, plant and equipment and
intangible assets at four general hospitals and three rehabilitation hospitals
and the cost of one undeveloped parcel of land have been written down to their
fair values.
 
    Restructuring charges of $37 million in fiscal 1995 were recorded in
connection with the AMH Merger. These charges included severance payments and
outplacement services for involuntary terminations of approximately 890 former
employees of the Company and other costs related to consolidating the operations
of the two companies. Restructuring charges of $77 million in fiscal 1994 were
recorded in connection with a plan to significantly decrease overhead costs
through a reduction in corporate and divisional staffing levels and to review
the resulting office space needs of all corporate operations.
 
    Interest expense, net of capitalized interest, was $312 million in 1996,
compared with $138 million in 1995 and $70 million in 1994. The increase between
1995 and 1996 was due primarily to the acquisition of AMH and the senior notes
and bank loans used to finance the acquisition and to retire debt in connection
with the AMH Merger.
 
    Investment earnings were $22 million in 1996, $27 million in 1995 and $28
million in 1994, and were derived primarily from notes receivable and
investments in debt and equity securities.
 
    Equity in earnings of unconsolidated affiliates was $20 million in 1996, $28
million in 1995 and $23 million in 1994. Substantially all of the decrease
between 1995 and 1996 is due to the exchange of the Company's investment in
Hillhaven for common stock in Vencor. During 1995 the Company's equity in the
earnings of Hillhaven was $16 million. In 1996 it was $7 million through the
date of the exchange and nothing thereafter. The Company's equity in the
earnings of Westminster was $6 million in 1995 and $7 million in 1996. The
Company sold its investment in Westminster in May 1996.
 
    Minority interest in income of consolidated subsidiaries increased in the
current year due to improved operating results at consolidated, but not
wholly-owned facilities and to the effects of minority interests recorded at
facilities acquired in the AMH Merger. Minority interest expense was $22 million
in 1996, $9 million in 1995 and $8 million in 1994.
 
    Taxes on income as a percentage of pretax income from continuing operations
were 47% in 1996, 41% in 1995 and 40% in 1994. The Company's effective tax-rate
increase in 1996 is primarily due to (i) additional amortization of goodwill
resulting from the AMH Merger and (ii) gains from the sales of international
operations. The amortization expense arising from the AMH Merger is a noncash
charge but provides no income tax benefits.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company's liquidity for the quarter ended August 31, 1996 was derived
principally from the cash proceeds of operating activities and borrowings under
the Company's unsecured revolving bank credit agreement. For the year ended May
31, 1996, additional liquidity was derived from disposals of assets and
investments, the public issuance of debt securities, realization of tax benefits
associated with losses from its discontinued psychiatric business, proceeds from
the exercises of performance investment plan options and borrowings under the
Company's existing credit facility. Net cash provided by operating activities
for the quarter ended August 31, 1996 was $39.3 million after expenditures of
$16.6 million for discontinued operations and restructuring charges. Net cash
provided by operating activities in the quarter ended August 31, 1995 was $60.8
million after expenditures of $16.3 million for discontinued operations and
restructuring charges. Net cash provided by operating activities for the year
ended May 31, 1996 was $195.0 million after net expenditures of $97.0 million
for discontinued operations and restructuring charges. Management believes that
cash flow from operations will continue to be positive. The Company's liquidity,
including cash provided by operating activities and amounts available under the
New Credit Facility is believed to be adequate to finance planned capital
expenditures, acquisitions and other known operating needs over the short-term
(up to 18 months) and the long-term (18 months to three years).
 
                                       44
<PAGE>
    The Company's cash and cash equivalents at August 31, 1996 were $104.1
million, an increase of $14.9 million from May 31, 1996. The ratio of total debt
to equity was 1.2 to 1.0 at August 31, 1996 and May 31, 1996. Working capital at
August 31, 1996 was $553.5 million, compared to $410.3 million at May 31, 1996.
At August 31, 1996 the current portion of long-term debt was $40.4 million
compared to $60.0 million at May 31, 1996.
 
    Cash proceeds from the sale of property and equipment in the quarter ended
August 31, 1996 were $40.3 million, primarily from the sale of the Company's
former corporate headquarters building in Santa Monica, California. Proceeds
from the sales of facilities, investments and other assets were $548.0 million
in the year ended May 31, 1996. During 1996 the Company sold its two hospitals
and related businesses in Singapore, its interests in a hospital in Malaysia and
in a hospital in Thailand and its interest in a company owning nine hospitals
and a pathology business in Australia. The net cash proceeds from all of these
sales aggregated approximately $324.0 million. In May 1996 the Company sold its
interest in Westminster for approximately $120.0 million. Also during 1996, the
Company received $91.8 million for the redemption of its Hillhaven preferred
stock.
 
    Cash payments for property and equipment were $43.4 million in the quarter
ended August 31, 1996, compared to $95.1 million in the quarter ended August 31,
1995. They were $370.0 million in the year ended May 31, 1996 and $264.0 million
in 1995. Capital expenditures for the Company, before any significant
acquisitions of facilities and other healthcare operations, are expected to be
approximately $300.0 million to $400.0 million annually. Such capital
expenditures relate primarily to the development of healthcare services networks
in selected geographic areas, design and construction of new buildings,
expansion and renovation of existing facilities, equipment additions and
replacements, introduction of new medical technologies and various other capital
improvements.
 
    During fiscal 1996, the Company spent $410.0 million for purchases of new
businesses. These included six general hospitals (or interests in hospitals) and
a number of physician practices.
 
BUSINESS OUTLOOK
 
    The challenge facing the Company and the healthcare industry is to continue
to provide quality patient care in an environment of rising costs, strong
competition for patients, and a general reduction of reimbursement by both
private and government payors. Because of national, state and private industry
efforts to reform healthcare delivery and payment systems, the healthcare
industry as a whole faces increased uncertainty. The Company is unable to
predict whether any healthcare legislation at the federal and/or state level
will be passed in the future, but it continues to monitor all proposed
legislation and analyze its potential impact in order to formulate the Company's
future business strategies.

(1) Merger transaction expenses for fiscal 1994 relate to the merger with
    American Healthcare Management Inc. ("American Healthcare") on April 19,
    1994.
 
(2) The restructuring charges for fiscal 1992 include $6.1 million for special
    executive compensation related to the employment of Charles N. Martin, Jr.,
    OrNda's Chairman, President and Chief Executive Officer, and $6.9 million
    related to employee severance and relocation expenses related to relocating
    the corporate office from Dallas, Texas to Nashville, Tennessee.
    Restructuring charges for fiscal 1994 relate to $2.5 million of special
    executive compensation related to the issuance of options to purchase stock
    to certain executives at prices below market.
 
(3) HNW is a 498-bed acute care facility located in Houston Texas. Effective
    January 1, 1996, OrNda purchased the controlling equity interests in HNW.
    Prior to January 1996, OrNda's investments in HNW consisted of (i) two
    classes of mandatorily redeemable preferred stock; (ii) a mortgage note
    receivable; and, (iii) prior to February 28, 1994, an investment in HNW's
    common stock. In applying the equity method of accounting for the investment
    prior to February 28, 1994, OrNda's investment in mandatorily redeemable
    preferred stock of HNW was considered an advance to HNW and was combined
    with the common stock. As a result, 100% of HNW's losses attributable to its
    common stock were recognized as losses to OrNda and reduced OrNda's combined
    investments in HNW. On February 28, 1994, OrNda irrevocably transferred its
    investment in common stock of HNW to the HNW Employee Stock Ownership Plan
    and HNW for nominal consideration. The effect of this transfer eliminated
    the requirement for OrNda to apply the equity method of accounting
    subsequent to February 28, 1994. Beginning March 1, 1994, OrNda's method of
    income recognition for its investments in HNW's mandatorily redeemable
    preferred stock was accretion of the HNW mandatorily redeemable preferred
    stock, recognition of cash dividends paid by HNW and accrual of cumulative,
    compounded, mandatorily redeemable dividend not paid by HNW.
 
(4) Per share information for the years ended August 31, 1992, 1993 and 1994 is
    based on primary shares because earnings per share assuming full dilution is
    anti-dilutive.
 
(5) The ratio of earnings to fixed charges is calculated by dividing income from
    continuing operations before income taxes plus fixed charges by fixed
    charges. Fixed charges consist of interest expense, including amortization
    of financing costs, and that portion of rental expense deemed to be
    representative of the interest component of rental expense. Earnings were
    inadequate to cover fixed charges by $68,836 for the year ended August 31,
    1992.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
           OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF ORNDA
 
    To provide prospective purchasers of the Notes with certain additional
information about OrNda, set forth below is the Management's Discussion and
Analysis of Financial Condition and Results of Operations of OrNda substantially
in the form included in OrNda's Annual Report on Form 10-K for the fiscal year
ended August 31, 1996.
 
    MERGERS AND ACQUISITIONS.  OrNda's recent operating results were
significantly affected by mergers, acquisitions and divestitures as discussed
below. As discussed in Note 2 to the accompanying consolidated financial
statements, OrNda completed the American Healthcare and Summit mergers on April
19, 1994. The American Healthcare merger was accounted for as a
pooling-of-interests and, accordingly, the operations of American Healthcare and
OrNda have been combined in the accompanying consolidated financial statements.
The Summit Merger was accounted for as a purchase and, accordingly, its
operations have been included since the date of the merger. The discussion
herein is based upon the combined operations of OrNda and American Healthcare
for all periods presented in the accompanying consolidated financial statements
and including Summit Health effective April 19, 1994. To enhance
understandability, discussion and analysis of financial condition and results of
operations of the separate companies is included, where necessary. For purposes
of "Management's Discussion and Analysis of Financial Condition and Results of
Operations of OrNda," references herein to OrNda include the operations of the
combined entity of OrNda and American Healthcare, unless the context requires
otherwise.
 
    In addition to the American Healthcare and Summit mergers, OrNda'a results
of operations have been impacted by the August 1994 acquisition of Fountain
Valley Regional Hospital and Medical Center ("Fountain Valley") and related
businesses in Fountain Valley, California, the February 1995 acquisition of
three hospitals and related businesses that comprise the St. Luke's Health
System ("St. Luke's") in Arizona, the January 1996 acquisition of HNW, the July
1996 acquisition of Cypress Fairbanks Medical Center in Houston, Texas ("Cypress
Fairbanks") and the August 1996 acquisition of Centinela Medical Center in
Inglewood, California ("Centinela").
 
    Cost in excess of net assets acquired ("Goodwill"), net of amortization,
increased approximately $179.8 million in fiscal 1996 primarily from goodwill
associated with the acquisitions of HNW ($100.0 million), Cypress Fairbanks
($24.4 million) and Centinela ($52.1 million). Goodwill, net of amortization,
increased approximately $43.9 million in fiscal 1995 primarily from the
acquisition of St. Luke's of $4.0 million; adjustments associated with the
acquisition of Fountain Valley of $2.9 million; in connection with the buy out
of a joint venture at one of OrNda's hospitals of $11.5 million; and, final
adjustments to the acquisition of Summit of $31.6 million. The adjustments to
the Summit goodwill resulted principally from the finalization of appraisals on
fixed assets acquired, resolution of certain assumed litigation, and receipt of
actuarial estimates on termination of pension plans.
 
    DIVESTITURES.  Effective in the third quarter of fiscal 1994, OrNda's
management decided upon a plan of disposition to sell Decatur Hospital in
Decatur, Georgia. During the fourth quarter of fiscal 1994, OrNda's management
also entered into plans to dispose of Lewisburg Community Hospital in Lewisburg,
Tennessee, Gibson General Hospital in Trenton, Tennessee, and Pasadena General
Hospital in Pasadena, Texas. These four hospitals have a total of 486 licensed
beds. OrNda consummated the sale of the Decatur Hospital in June 1994 and the
sale of the Gibson Hospital effective October 31, 1994. Effective December 31,
1994, OrNda sold Ross Hospital, a 92-bed psychiatric facility in Kentfield,
California.
 
    OrNda sold the hospital in Lewisburg on March 1, 1995 and had definitive
agreements to lease the Pasadena General Hospital real property and sell the
operations of Pasadena General Hospital to the lessee. The lessee assumed
ownership of operations and began leasing Pasadena General Hospital on March 3,
1995. On or about March 27, 1995, OrNda became aware that the buyer/lessee of
Pasadena had failed to perform under its contractual agreement. On March 31,
1995, OrNda re-assumed management of the facility until the facility was closed
on May 14, 1995. On July 7, 1995, OrNda entered into a definitive agreement to
sell the real property of Pasadena General Hospital to a third party. The sales
price resulted in an additional loss on sale of $5.7 million which was recorded
in the third quarter of fiscal 1995. The above noted divestitures did not have a
significant impact on subsequent operations.

    GEOGRAPHIC CONCENTRATION.  OrNda operates hospitals in greater southern
California, south Florida, Arizona and Texas which generated the following
percentages of OrNda's total revenue for the years ended August 31, 1995 and
1996, respectively:

    To the extent favorable or unfavorable changes in regulations or market
conditions occur in these areas, such changes would likely have a corresponding
impact on OrNda's results of operations.
 
RESULTS OF OPERATIONS
 
    GENERAL TRENDS.  During the periods discussed below, OrNda's results of
operations were affected by certain industry trends, changing components of
total revenue, and changes in OrNda's debt structure. OrNda's results of
operations have also been impacted by the mergers, acquisitions and divestitures
discussed above.
 
    INDUSTRY TRENDS.  Outpatient services accounted for 31.3% and 28.8% of
actual gross patient revenue for the years ended August 31, 1996 and 1995,
respectively, reflecting the industry trend towards greater use of outpatient
services and the expansion of OrNda's outpatient services primarily achieved
through the opening of new outpatient clinics in key markets in fiscal 1996 and
1995. OrNda expects the industry trend towards outpatient services to continue
as procedures currently being performed on an inpatient basis become available
on an outpatient basis through technological and pharmaceutical advances. OrNda
plans to provide quality health care services as an extension of its hospitals
through a variety of outpatient activities including surgery, diagnostics,
physician clinics and home health.
 
    As discussed below, excluding the effect of the acquisitions and the
divestitures noted above ("same-hospitals basis"), total revenues have
increased, reflecting higher utilization of outpatient and ancillary services,
increased acuity of patients admitted, and an increase in admissions for
inpatient procedures. The impact on revenue of increased patient acuity and
general price increases has been partially offset by the increasing proportion
of revenues derived from managed care providers. These major payors
substantially pay on a fixed payment rate on a per patient or a per diem basis
instead of a cost or charge reimbursement methodology. Fixed payments limit the
ability of OrNda to increase revenues through price increases. While these fixed
payment rates have increased annually, the increases have historically been at a
rate less than OrNda's increases in costs, and have been inadequate to reflect
increases in costs associated with improved medical technologies. OrNda has been
able to mitigate such inflationary pressures through cost control programs, as
well as utilization management programs which reduce the number of days that
patients stay in the hospital and the amount of hospital services provided to
the patient. The average length of stay has decreased from 5.3 days for the year
ended August 31, 1995 to 5.0 days for the year ended August 31, 1996. OrNda has
programs designed to improve the margins associated with the revenues derived
from government payors and managed care providers. In addition, OrNda has
programs designed to enhance overall hospital margins.
 
  YEAR ENDED AUGUST 31, 1996 COMPARED WITH THE YEAR ENDED AUGUST 31, 1995.
 
    Total revenue for the year ended August 31, 1996 increased over the same
period in the prior year by $304.5 million or 16.5% to $2.1 billion. The 16.5%
increase is primarily a result of the acquisitions discussed above as well as an
increase in same hospitals revenue as discussed below. The increase in total
revenue attributable to acquisitions, net of divestitures, was $179.9 million.
Net income applicable to
 
                                       49
<PAGE>
common shares for the year ended August 31, 1996 was $99.5 million, or $1.73 per
share, compared to $69.3 million, or $1.53 per share, in the same period last
year.
 
    Operating expenses in the year ended August 31, 1996 increased 14.1% ($222.1
million) compared to the same period in the prior year primarily as a result of
acquisitions and the increase in same hospital revenues and volumes discussed
below.
 
    On a same-hospitals basis, total revenue increased 7.6% ($124.6 million)
primarily as a result of a 2.9% increase in admissions and a 13.5% increase in
gross outpatient revenue. On a same-hospitals basis, salaries and benefits
increased as a percent of total revenue from 45.3% in fiscal 1995 to 45.4% in
fiscal 1996. Supplies expense increased 11.4% ($24.1 million) and as a
percentage of total revenue increased from 12.8% in fiscal 1995 to 13.3% in
fiscal 1996. Purchased services decreased 5.6% ($10.6 million) and as a
percentage of total revenue decreased from 11.6% in fiscal 1995 to 10.2% in
fiscal 1996 primarily due to a reclassification in fiscal 1996 of the supply
component of major contracts from purchased services to supplies expense. The
provision for doubtful accounts increased 1.1% ($1.3 million) but decreased from
7.1% of total revenue for the year ended August 31, 1995 to 6.7% for the year
ended August 31, 1996. Other operating expenses increased 7.0% ($9.5 million)
and as a percentage of total revenue was 8.3% in fiscal 1995 and 1996.
 
    The effect of price increases implemented by OrNda's hospitals was nominal
as gross revenue from fixed reimbursement third-party payors represented
approximately 87.5% of OrNda's total gross revenue in 1996. Over the last
several years, the portion of OrNda's total revenue derived from fixed
reimbursement third-party payors has increased while rates of increases from
these payors have generally been less than medical-related inflation, resulting
in increased efforts by OrNda to implement cost containment initiatives and
re-evaluate hospital programs for adequacy of profitability. Since these trends
are likely to continue, OrNda's ability to improve operating results at its
existing hospitals is dependent on its continued effectiveness in reducing its
costs of services. OrNda's operations may also be enhanced through strategic
acquisitions as was particularly evident in fiscal 1994 and fiscal 1995 with the
mergers with American Healthcare and Summit and the individual hospital
acquisitions. OrNda intends to pursue strategic acquisitions of health care
providers in geographic areas and with service capabilities that will facilitate
the development of integrated networks.
 
    Depreciation and amortization for fiscal 1996 increased 21.9% ($18.7
million) over the prior year primarily as a result of the acquisitions of St.
Luke's, HNW, Cypress Fairbanks and Centinela. The increase in depreciation and
amortization attributable to acquisitions, net of divestitures, was $11.1
million. In addition, amortization on intangibles increased as a result of new
business units.
 
    Interest expense for fiscal 1996 as compared to the same period last year
decreased 1.7% ($1.9 million) primarily as a result of a decline in the average
debt balance outstanding and improved pricing under the existing credit
facility. Such decrease was partially reduced by the effect of a $2.2 million
reduction in interest expense in the third quarter of fiscal 1995 related to an
interest rate swap agreement. Of OrNda's total indebtedness of $1.3 billion at
August 31, 1996, approximately $692.2 million bears interest at rates that
fluctuate with market rates, such as the Prime Rate or LIBOR. Increases in
market interest rates will adversely affect OrNda's net income.
 
    Minority interest, which represents the amounts paid or payable to
physicians pursuant to OrNda's joint venture arrangements, increased $7.5
million in fiscal 1996 as compared to fiscal 1995, primarily as a result of a
$9.4 million exchange of minority interest ownership in two hospitals for
minority interest investment in two group physician practices in the first
quarter of fiscal 1996 and the acquisition of HNW which had existing joint
ventures.
 
    In fiscal 1996, OrNda recorded income of $5.1 million, compared to $14.0
million in fiscal 1995, related to its investments in HNW which primarily
represented non-cash income related to OrNda's investment in HNW redeemable
preferred stock. Effective January 1, 1996, OrNda acquired HNW from the
hospital's ESOP. Following the transaction, HNW became a wholly owned subsidiary
of OrNda. See Note 2 to the accompanying consolidated financial statements for
further discussion of OrNda's investments in HNW as well as the acquisition of
HNW.
 
                                       50
<PAGE>
    OrNda accounts for income taxes in accordance with Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS No. 109").
The majority of OrNda's deferred tax assets related to approximately $198.9
million of tax loss and credit carryforwards at August 31, 1996, which OrNda has
available to offset future taxable income. The American Healthcare merger (see
Note 2 to the consolidated financial statements) caused an "ownership change"
within the meaning of Section 382(g) of the Internal Revenue Code (the "IRC")
for both OrNda and American Healthcare. Consequently, allowable federal
deductions relating to tax attribute carryforwards of OrNda and American
Healthcare arising in periods prior to the merger are thereafter subject to
annual limitations (OrNda - $19.0 million; American Healthcare - $16.0 million).
For American Healthcare, such tax attribute carryforwards can only be applied
against the prospective taxable income of the entities that previously comprised
American Healthcare. These limitations may be increased for "built-in-gains," as
defined under the IRC, recognized during a five-year period following the date
of the merger. Management assesses the realizability of the deferred tax assets
on at least a quarterly basis and currently is satisfied, despite the annual
limitations, that it is more likely than not that the deferred tax assets
recorded at August 31, 1996, net of the valuation allowance, will be realized
through reversal of deferred tax liabilities.
 
    For the year ended August 31, 1996, OrNda recorded income tax expense of
$35.2 million on pre-tax income of $135.1 million, an amount less than the
statutory rate, primarily due to the availability of net operating loss
carryforwards.
 
  YEAR ENDED AUGUST 31, 1995 COMPARED WITH THE YEAR ENDED AUGUST 31, 1994.
 
    Total revenue for the year ended August 31, 1995, increased over the prior
year by $568.3 million or 44.6% to $1.8 billion. The 44.6% increase is primarily
a result of the Summit merger and other hospital acquisitions discussed above.
The increase in total revenue attributable to acquisitions, net of divestitures
was $496.5 million. Net income applicable to common shares for the year ended
August 31, 1995, was $69.3 million, or $1.53 per share compared to a net loss of
$61.2 million, or $(1.62) per share in prior year.
 
    Operating expenses for the year ended August 31, 1995, increased 44.4%
($485.8 million) over the prior year primarily as a result of the acquisitions
discussed above. Actual salaries and benefits as a percentage of total revenue
declined from 45.1% in fiscal 1994 to 43.6% in fiscal 1995 mainly as a result of
reductions in corporate office personnel attained in combining the OrNda and
American Healthcare corporate offices and due to labor efficiencies achieved at
certain facilities.
 
    Actual other operating expenses increased 35.2% ($55.1 million). This
category of expense increased at a rate greater than other categories due to the
1994 acquisition of Summit, which owns a Medicaid HMO that includes the majority
of its non-salary expenses in other operating expense. In addition, the St.
Luke's acquisition in fiscal 1995 also included a Medicaid HMO. Operating
expenses for the year ended August 31, 1995, increased approximately $17.4
million for claims payments made by the Medicaid HMO to third-party providers.
In addition, other operating expenses increased $12.3 million for rent expense
related to acquisitions financed through leasing agreements with third parties.
 
    On a same-hospitals basis, total revenue increased 6.9% ($71.9 million)
primarily as a result of a 3.9% increase in admissions and a 18.7% ($105.2
million) increase in gross outpatient revenue. On a same-hospitals basis,
salaries and benefits increased 8.7% ($41.7 million) primarily due to
inflationary increases and an increase in same hospital revenue. Supplies
expense increased 3.9% ($5.0 million) and as a percentage of total revenue
decreased from 12.4% in fiscal 1994 to 12.1% in fiscal 1995, primarily as a
result of favorable reductions in expenses under supply contracts in
pharmaceuticals and other areas. Purchased services increased 3.5% ($4.0
million) but as a percentage of total revenue remained at 14.4% in fiscal 1994
and fiscal 1995 primarily as a result of increases in marketing and rent
expenses. Other operating expenses increased 10.1% ($9.2 million) and as a
percentage of total revenue increased from 8.8% in fiscal 1994 to 9.0% in fiscal
1995, primarily as a result of increases in marketing and rent expenses. The
provision for doubtful accounts increased 17.0% ($12.4 million) and increased
from 7.0% of total revenue in 1994 to 7.6% in 1995. In connection with the
American Healthcare and Summit mergers, during the year ended August 31, 1994,
OrNda changed the methodologies used by the previously separate companies to
calculate the allowance for doubtful accounts to conform to a single method for
OrNda and
 
                                       51
<PAGE>
American Healthcare which resulted in a $3.3 million favorable impact on the
provision for doubtful accounts in 1994.
 
    Depreciation and amortization for the year ended August 31, 1995, increased
27.6% ($18.4 million) over the prior year primarily as a result of the Summit
merger and other acquisitions discussed previously. The increase in depreciation
and amortization attributable to acquisitions, net of divestitures, was $19.1
million.
 
    Interest expense increased 30.8% ($25.7 million) as a result of additional
indebtedness incurred to finance the acquisitions discussed above as well as
increases in market interest rates. Such increase was partially offset by a
decrease in interest expense of $2.2 million related to an interest rate swap
agreement in the third quarter of fiscal 1995. Of OrNda's total indebtedness of
$1.1 billion at August 31, 1995, approximately $480.2 million bore interest at
rates that fluctuate with market rates, such as the Prime Rate or LIBOR. Market
interest rates increased from 1994 to 1995 causing OrNda's interest expense to
increase.
 
    Minority interest, which represents the amounts paid or payable to
physicians pursuant to OrNda's joint venture arrangements, decreased 94.0% ($3.8
million) in fiscal 1995 as compared to fiscal 1994, primarily as a result of the
repurchase of joint venture interests and a decline in operations at certain of
OrNda's joint ventures.
 
    In fiscal 1995, OrNda recorded income of $14.0 million, compared to $3.6
million in fiscal 1994, related to its investments in HNW which primarily
represented non-cash income related to OrNda's investment in HNW redeemable
preferred stock. See Note 2 to the accompanying consolidated financial
statements for further discussion of OrNda's investments in HNW.
 
    For the year ended August 31, 1995, OrNda recorded income tax expense of
$15.8 million on pretax income of $87.1 million, an amount less than the
statutory rate, primarily due to the availability of net operating loss
carryforwards.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    At August 31, 1996, OrNda had working capital of $88.1 million, of which
$17.4 million was cash, compared with $5.4 million at August 31, 1995. OrNda's
cash portion of working capital is primarily managed through a revolving credit
arrangement, whereby excess cash generated through operations or otherwise is
generally used to reduce the outstanding revolving credit facility. When cash
requirements arise, the revolving credit facility is drawn upon as needed. On
October 27, 1995, OrNda executed its existing revolving credit facility to
increase its borrowing capacity from $660.0 million to $900.0 million. Under the
terms of its existing credit facility, as of August 31, 1996, OrNda had $146.6
million of borrowing capacity available for general corporate purposes and
acquisitions. See Note 5 to the accompanying consolidated financial statements
for further discussion of its existing credit facility. The existing credit
facility was amended on November 27, 1996 to increase OrNda's borrowing capacity
to $1.2 billion. The existing credit facility matures on October 30, 2001 and is
classified as long-term debt on OrNda's balance sheet.
 
    In fiscal 1996, OrNda's operating activities provided cash of $154.4
million. Cash from operations was used for the $16.2 million increase in patient
accounts receivable, net of the provision for doubtful accounts. The increase in
patient accounts receivable resulted primarily from the increase in same store
revenues, delays in payment from certain state Medicaid/Medicare programs and
due to the acquisition and start-up of new business units during fiscal 1996.
Cash from operations was used for income tax payments of $28.9 million and
interest payments of $107.4 million. Such uses were partially offset by $20.6
million of proceeds from sales of an investment security classified as trading.
 
    Net cash used in investing activities of $532.6 million during fiscal 1996
consisted primarily of capital expenditures of $102.6 million and $431.2 million
for the acquisitions of hospitals and related assets. OrNda's management
currently expects to incur approximately $125.0 million of capital expenditures
in fiscal 1997 for replacement equipment and construction at existing
facilities.
 
                                       52
<PAGE>
    Net cash provided by financing activities for the year ended August 31, 1996
of $390.7 million resulted primarily from $199.3 million sale of common stock
and exercise of stock options and the $200.6 million excess of long-term debt
borrowings over principal payments on long-term debt. On November 6, 1995, OrNda
completed the sale of 10,000,000 shares of its common stock at a $17.625 per
share public offering price. On November 9, 1995, the underwriters exercised an
option to purchase an additional 1,500,000 shares to cover over-allotments. The
net proceeds of approximately $192.3 million, after deducting offering expenses
and underwriting discounts, was used to reduce the indebtedness under the
revolving portion of the existing credit facility in the amount of $27.2 million
and for general corporate purposes.
 
    On November 7, 1995, OrNda issued a notice of redemption to the holders of
its Payable in Kind Cumulative Redeemable Convertible Preferred Stock (the "PIK
Preferred") for $15 per share with a redemption date of December 8, 1995. In the
quarter ended November 30, 1995, 1,355,519 shares of PIK Preferred were
converted into 1,355,519 shares of OrNda's common stock and 7,416 shares of the
PIK Preferred remained outstanding. On December 8, 1995, the remaining 7,416
shares of PIK Preferred were redeemed for $15 per share plus dividends of $0.16
per share accrued through the redemption date.
 
    OrNda believes that its cash flows generated by operations together with
availability of credit under its existing credit facility will be sufficient to
meet its short and long-term operational cash needs. However, OrNda's net
debt-to-total-capitalization ratio at August 31, 1996 is 66.5%. Such leverage
limits the amount of additional indebtedness available to OrNda for acquisitions
(including certain announced and pending acquisitions) requiring capital in
excess of amounts currently available under its existing credit facility. On
November 27, 1996, OrNda increased its credit facility to $1.2 billion, an
amount sufficient to finance its announced and pending acquisitions. Alternative
financing may also be available under other arrangements, such as
off-balance-sheet financing arrangements.
 
    As of August 31, 1996, OrNda had approximately $692.2 million of debt
outstanding under its existing credit facility with an interest rate of LIBOR
plus 1.25%. Interest rates in the future may be subject to upward and downward
adjustments based on OrNda's leverage ratio. Such credit facility is expected to
be repaid as part of the Refinancing.
 
    The ratio of earnings to fixed charges and preferred stock dividends was
0.51, 1.61 and 1.99 for the years ended August 31, 1994, 1995 and 1996,
respectively. The ratio of earnings to fixed charges and preferred stock
dividends is calculated by dividing earnings before income taxes plus fixed
charges by the sum of fixed charges which consists of interest expense,
amortization of financing costs, preferred stock dividends and the portion of
rental expense which is deemed to be representative of the interest component.
The ratio of earnings to fixed charges and preferred stock dividends is an
indication of OrNda's ability to pay interest expense and other fixed charges.
 
    In recent years the IRS was examining the federal income tax returns for
fiscal years 1984, 1985 and 1986 of Summit, which became a wholly-owned
subsidiary of OrNda in April 1994 and merged into OrNda in September 1994.
Summit received a revenue agent's report from the IRS with proposed adjustments
for the years 1984 through 1986 aggregating as of August 31, 1996 approximately
$16.6 million of income tax, $66.4 million of interest on the tax, $43.9 million
of penalties and $25.6 million of interest on the penalties. After receiving the
revenue agent's report, Summit filed a protest contesting the proposed
adjustments. On October 28, 1996, OrNda entered into a Closing Agreement on
Final Determination with the IRS for the above audit period, by agreeing and
paying additional tax of $647,000 and interest of $888,000 to close the audit of
Summit for the fiscal years 1984 through 1986. The Closing Agreement is subject
to review by the Joint Congressional Committee on Taxation since the matter
relates to a refund of taxes to Summit in excess of $1 million.
 
    INFLATION. A significant portion of OrNda's operating expenses are subject
to inflationary increases, the impact of which OrNda has historically been able
to substantially offset through charge increases, expanding services and
increased operating efficiencies. To the extent that inflation occurs in the
future, OrNda may not be able to pass on the increased costs associated with
providing health care services to patients with government or managed care
payors, unless such payors correspondingly increase reimbursement rates.

GENERAL
 
    Tenet is the second largest investor-owned healthcare services company in
the United States. Tenet's subsidiaries own or operate general hospitals and
related healthcare facilities serving urban and rural communities in 13 states
and hold investments in other healthcare companies. At October 31, 1996, Tenet's
subsidiaries and affiliates operated 76 general hospitals with 17,350 licensed
beds. Tenet's subsidiaries also own or operate various ancillary healthcare
businesses, including outpatient surgery centers, home healthcare programs,
ambulatory, occupational and rural healthcare clinics, a health maintenance
organization with approximately 58,000 members, a preferred provider
organization and a managed care insurance company as well as a small number of
rehabilitation hospitals, specialty hospitals, long-term care facilities and
psychiatric facilities. Tenet intends to continue its strategic acquisitions of
and partnerships with additional hospitals in order to expand and enhance its
integrated healthcare delivery systems. For the 12 months ended August 31, 1996,
Tenet had net operating revenues, EBITDA and income from continuing operations,
adjusted to reflect acquisitions, divestitures and related adjustments, of $5.9
billion, $1.1 billion and $226.3 million, respectively. See "Pro Forma Financial
Information."
 
    At October 31, 1996, Tenet's investments in other healthcare companies
included: (i) an approximately 12.1% interest in Vencor, which operates nursing
homes and other healthcare businesses, (ii) an approximately 11.6% interest in
TRC, which operates kidney dialysis units and certain related healthcare
businesses and (iii) an approximately 23% interest in Health Care Property
Partners ("HCPP"). See "--Investments."
 
    As a result of the Merger, OrNda will become a wholly owned subsidiary of
the Company. OrNda is the third largest investor-owned provider of healthcare
services in the United States, delivering a broad range of inpatient and
outpatient healthcare services to urban and suburban communities in 15 states.
At October 31, 1996, OrNda operated 49 general hospitals with a total of 9,599
licensed beds, six surgery centers, numerous outpatient and specialty clinics,
one psychiatric hospital and a Medicaid HMO with approximately 34,000
participants. For the year ended August 31, 1996, OrNda had net operating
revenues, EBITDA and income from continuing operations, adjusted to reflect
acquisitions and related adjustments, of $2.8 billion, $409.9 million and $106.4
million, respectively. See "Pro Forma Financial Information."
 
    Following the Merger, the Company will operate 125 general hospitals serving
urban and rural communities in 22 states, with a total of 26,949 licensed beds,
excluding pending acquisitions. For the 12 months ended August 31, 1996, on a
pro forma combined basis, the Company's net operating revenues, EBITDA and
income from continuing operations, including the Pending Acquisitions, would
have been approximately $8.7 billion, $1.6 billion and $339.7 million,
respectively. See "Pro Forma Financial Information." These pro forma combined
results do not give effect to certain cost savings that management believes may
be realized following the Merger. No assurances can be made as to the amount of
cost savings, if any, that actually will be realized.
 
    Tenet believes that the Merger represents an opportunity to acquire a
substantial portfolio of hospitals providing quality care responsive to the
current managed care environment. Many of OrNda's general hospitals are located
in geographic areas where Tenet currently operates hospitals, including southern
California and south Florida. The Merger will provide an opportunity for the
Company to coordinate the services it provides in these geographic areas with
those services provided by OrNda, which the Company believes will accelerate its
development of integrated healthcare delivery systems in these areas. The Merger
also expands the Company's operations into several new geographic areas,
including Arizona, Iowa, Massachusetts, Mississippi, Nevada, Oregon, Washington,
West Virginia and Wyoming. The Company believes it will be able to integrate
effectively OrNda's operations based on its successful integration of the
operations of AMH, which was acquired by Tenet in March 1995.
 
                                       54
<PAGE>
BUSINESS STRATEGY
 
    The Company's strategic objective is to provide quality healthcare services
responsive to the current managed care environment. Tenet believes that
competition among healthcare providers occurs primarily at the local level.
Accordingly, the Company tailors its local strategies to address the specific
competitive characteristics of the geographic areas in which it operates,
including the number of facilities operated by Tenet, the nature and structure
of physician practices and physician groups, the extent of managed care
penetration, the number and size of competitors and the demographic
characteristics of the area. Key elements of the Company's strategy are:
 
    - to develop integrated healthcare delivery systems by coordinating the
      operations and services of the Company's facilities with other hospitals
      and ancillary care providers and through alliances with physicians and
      physician groups;
 
    - to reduce costs through enhanced operating efficiencies while improving
      the quality of care provided;
 
    - to develop and maintain its strong relationships with physicians and
      generally to foster a physician-friendly culture;
 
    - to enter into discounted fee for service arrangements, capitated contracts
      and other managed care contracts with third party payors; and
 
    - to acquire and enter into strategic partnerships with hospitals, groups of
      hospitals, other healthcare businesses, ancillary healthcare providers,
      physician practices and physician practice assets where appropriate to
      expand and enhance quality integrated healthcare delivery systems
      responsive to the current managed care environment.
 
    DEVELOP INTEGRATED HEALTHCARE DELIVERY SYSTEMS.  In each geographic area it
serves, the Company has established or is developing an integrated healthcare
delivery system to offer a full range of quality patient care responsive to the
current managed care environment by coordinating the services offered by its
hospitals and related facilities with the services offered by other providers.
The Company believes that general hospitals will serve as the hubs for the
development of integrated healthcare delivery systems due to their highly
developed infrastructure, extensive service base, sophisticated equipment and
skilled personnel.
 
    The Company's strategy is implemented in a number of ways depending upon the
characteristics of the local area. In areas where there is significant managed
care penetration or in which the Company anticipates such penetration, the
Company encourages physicians practicing at its hospitals to form independent
physician associations ("IPAs"). As part of its strategy, the Company intends to
form physician hospital organizations ("PHOs") that bring together its hospitals
and IPAs, physicians or physician groups under a variety of arrangements to
negotiate for managed care contracts, including capitated contracts. Tenet has
formed a PHO for the New Orleans area and is in the process of forming PHOs in
several other geographic areas. The Company also has formed management service
organizations ("MSOs"), which provide management and administrative services to
physicians, physician group practices and IPAs, and which enter into managed
care contracts on behalf of these groups and, in certain circumstances in the
future, PHOs. Where appropriate, the Company also purchases physician and
physician group practices and employs such physicians or purchases the assets of
those practices and manages such practices through its MSOs or otherwise.
 
    The Company uses various combinations of one or all of the foregoing methods
in each geographic area to create a community of interest between its hospitals
and the physicians who practice there, to which it adds additional resources,
where necessary, to create an integrated healthcare delivery system capable of
providing a full range of healthcare services to the community. One example of
how this integrated delivery strategy is being implemented is the Company's
Redding Medical Center, a tertiary care hospital located in a primarily rural
area in northern California, around which hospital the Company is developing
such a system, with the hospital itself acting as the hub. Affiliations with
physician practices, non-Tenet primary care hospitals, an outpatient surgery
center developed in partnership with local physicians and
 
                                       55
<PAGE>
affiliated ancillary care providers in the surrounding area enable this system
to provide a full range of healthcare services. In addition, the Company
recently has introduced its HMO product to this geographic area. The Company
believes that the development of such integrated healthcare delivery systems
will enhance its ability to contract with payors in those areas that have
experienced or will experience a high degree of managed care penetration.
 
    The Company believes that the Merger will enhance its ability to expand and
enhance its integrated healthcare delivery systems. In south Florida, Tenet will
be able to expand its existing Tenet South Florida HealthSystem with the
inclusion of OrNda's four general hospitals and related healthcare operations
with Tenet's eight existing general hospitals and related heathcare operations.
In southern California, Tenet plans to continue to develop and expand its
existing healthcare delivery system, which would combine OrNda's 19 hospitals
and related healthcare operations with Tenet's existing 15 hospitals and related
healthcare operations. These systems will provide a full range of services over
a large geographic area. In addition, the Merger will extend the Company's
operations into several additional geographic areas, some of which do not yet
exhibit (and in some cases are not expected to exhibit in the near term) the
high degree of managed care penetration experienced in California and in certain
other parts of the country.
 
    REDUCE COSTS THROUGH ENHANCED OPERATING EFFICIENCY WHILE IMPROVING THE
QUALITY OF CARE.  The Company continues to position itself as a provider of
quality healthcare services responsive to the current managed care environment
by enhancing operating efficiencies at the hospital, regional and corporate
levels. For example, the Company has implemented programs at the hospital level
to monitor and adjust staffing levels in response to patient acuity and hospital
census, and to improve service and the quality of outcomes while reducing
operating expenses through the reengineering of the delivery of patient care in
its hospitals. At several of the Company's hospitals, job functions have been
redefined and services have been moved directly to the patient floors. Tenet
believes that increasing the amount of patient care delivered at the bedside
will increase patient satisfaction while reducing costs. This initiative also
has enhanced the ability of professionals to focus their attention on higher
levels of patient care.
 
    In order to reduce costs and achieve economies of scale at the regional
level, the Company has combined the hospital business offices of facilities
located in close geographic proximity. Consolidating business offices allows the
Company's hospitals to reduce staffing levels while enhancing the effectiveness
of their billing and collection efforts. The Company also has reduced costs and
achieved economies of scale at the hospital, regional and corporate levels by
consolidating the collection of accounts receivable through SOS and negotiating
purchase contracts that take greater advantage of its group purchasing program.
In addition, management believes that certain cost savings may be realized
following the Merger. No assurances can be made as to the amount of cost
savings, if any, that actually will be realized.
 
    DEVELOP AND MAINTAIN STRONG RELATIONSHIPS WITH PHYSICIANS.  Tenet believes
that its success will depend in large part on maintaining strong relationships
with physicians, including physicians previously associated with OrNda. To
better serve the needs of its patients, Tenet has devoted substantial management
effort and resources to establishing and maintaining such relationships and to
fostering a physician-friendly culture at each of its hospitals. The Company
attracts physicians to its hospitals by equipping its hospitals with
technologically advanced equipment, sponsoring training programs to educate
physicians on advanced medical procedures, using governing boards for each
hospital, the sole voting members of which are physicians and community members,
to develop short and long-term plans for the hospital and review and approve, as
appropriate, actions of the medical staff, including staff appointments,
credentialing, peer review and quality assurance, and otherwise creating an
environment within which physicians prefer to practice. The Company often is at
the forefront in introducing new services, medical equipment and medical
technologies designed to improve patient care and assist physicians. These
efforts serve the dual purposes of developing and maintaining strong
relationships with physicians and better serving the needs of patients.
 
    The Company looks to physicians to play an active role in the governance of
its hospitals. For example, each of the Company's hospitals has a governing
board, the only voting members of which are physicians who are active members of
the medical staff and local community members. The Company has
 
                                       56
<PAGE>
no voting representatives on any of its hospitals' governing boards. These
boards develop short and long-term plans for the hospitals and review and
approve, as appropriate, actions of the medical staff, including staff
appointments, credentialing, peer review and quality assurance. The Company also
maintains a physician advisory board that provides advice to the Company with
respect to long-term strategy, emerging technologies, training programs and
significant hospital operational issues. This advisory board serves as another
vehicle through which physicians on the staffs of the Company's hospitals can
communicate their views to the Company.
 
    ENTER INTO MANAGED CARE CONTRACTS.  The Company believes that its extensive
experience operating in California, which has a high degree of managed care
penetration, will enhance its ability to compete successfully in other
geographic areas that are experiencing an increase in managed care. Pressures to
control healthcare costs have resulted in a continuing increase in the
percentage of the United States population that is covered by managed healthcare
plans. To increase the cost-effectiveness of healthcare delivery, managed care
payors have introduced new utilization review systems, increased the use of
discounted and capitated fee arrangements and have attempted, where appropriate,
to direct patients to less intensive alternatives along the continuum of patient
care. Managed care payors typically require members or provide financial
incentives for members to utilize only those healthcare providers that have
contracted with such payors to provide care on a discounted or capitated basis.
Accordingly, in order to maintain and increase their patient base as managed
care penetration increases, it is important for providers to enter into such
contracts. In determining with which providers to contract, payors consider,
among other factors, the quality of care provided, the range of services, the
geographic coverage and the cost-effectiveness of the care provided. Tenet
believes that the development and expansion of its integrated healthcare
delivery systems will enable it to better compete for managed care contracts,
which, in turn, should allow it to expand its patient volume and cash flow,
notwithstanding the reduced rates at which services may be provided under such
contracts.
 
    PURSUE STRATEGIC ACQUISITIONS AND PARTNERSHIPS.  The Company intends to
continue to pursue strategic acquisitions of and partnerships with hospitals,
other healthcare businesses, ancillary healthcare providers, physician practices
and physician practice assets, where appropriate, to expand and enhance its
integrated healthcare delivery systems. One example of a recent strategic
acquisition is the Company's June 1996 acquisition of Hialeah Hospital, a
378-bed general hospital located in Hialeah, Florida. Hialeah Hospital's
location in north Dade County enhanced the geographic coverage of the Tenet
South Florida HealthSystem and increased the number of general hospitals in that
system to seven. Tenet believes that significant opportunities will exist to
enter into additional partnerships and make strategic acquisitions, including
partnerships with and acquisitions of tax-exempt hospitals and physician groups
or physician practice assets, where appropriate. On a pro forma basis,
immediately following the Merger and the Refinancing the Company expects to have
approximately $[ ] million available under the New Credit Facility to take
advantage of strategic acquisition and partnership opportunities.
 
DOMESTIC HEALTH CARE OPERATIONS
 
    As a result of the Merger, the Company will operate 125 general hospitals
serving communities in 22 states, before taking into account the Pending
Acquisitions. On a combined basis, Tenet's and OrNda's general hospitals had a
total of 26,949 licensed beds at October 31, 1996. In addition, the Company and
OrNda operate numerous ancillary healthcare facilities, including a small number
of rehabilitation hospitals, long-term care facilities and psychiatric
facilities located on the same campus as, or nearby, their general hospitals,
and operated all or a substantial part of [ ] medical office buildings as of
October 31, 1996. With the exception of one general hospital that was acquired
in fiscal 1996 and that is in the process of becoming accredited for the first
time, each of the Company's and OrNda's facilities that is eligible for
accreditation is fully accredited by the Joint Commission on Accreditation of
Healthcare Organizations ("JCAHO"), the Commission on Accreditation of
Rehabilitation Facilities (in the case of the rehabilitation hospitals) or
another appropriate accreditation agency. With such accreditation, the Company's
and OrNda's hospitals are eligible to participate in the Medicare and Medicaid
programs.
 
                                       57
<PAGE>
    Each of Tenet's and OrNda's general hospitals offers acute care services and
most offer operating and recovery rooms, radiology services, intensive care and
coronary care nursing units, pharmacies, clinical laboratories, respiratory
therapy services, physical therapy services and outpatient facilities. A number
of the hospitals also offer tertiary care services such as open heart surgery,
neonatal intensive care, neuroscience, orthopedics services and oncology
services. Three of the Company's hospitals, Memorial Medical Center (formerly
known as Mercy+Baptist Medical Center), USC University Hospital and Sierra
Medical Center, offer quartenary care in such areas as heart, lung, liver and
kidney transplants and USC University Hospital and Sierra Medical Center also
offer gamma knife brain surgery.
 
    Technological developments permitting more procedures to be performed on an
outpatient basis, in conjunction with pressures to contain healthcare costs,
have led to a shift from inpatient care to ambulatory or outpatient care. Tenet
has responded to this trend by enhancing its hospitals' outpatient service
capabilities, including (i) establishing freestanding outpatient surgery centers
at or near certain of its hospital facilities, (ii) reconfiguring certain
hospitals to more effectively accommodate outpatient treatment by, among other
things, providing more convenient registration procedures and separate
entrances, and (iii) restructuring existing surgical capacity to allow a greater
number and range of procedures to be performed on an outpatient basis. Tenet's
facilities will continue to emphasize those outpatient services that can be
provided on a quality, cost-effective basis and that the Company believes will
experience increased demand. The patient volumes and net operating revenues at
both the Company's general hospitals and its outpatient surgery centers are
subject to seasonal variations caused by a number of factors, including but not
necessarily limited to, seasonal cycles of illness, climate and weather
conditions, vacation patterns of both patients and physicians and other factors
relating to the timing of elective procedures.
 
    In addition, inpatient care is continuing to move from acute care to
sub-acute care, where a less-intensive level of care is provided. Tenet has been
proactive in the development of a variety of sub-acute inpatient services to
utilize a portion of its unused capacity, thereby retaining a larger share of
overall healthcare expenditures. By offering cost-effective ancillary services
in appropriate circumstances, Tenet is able to provide a continuum of care where
the demand for such services exists. For example, in certain hospitals the
Company has developed transitional care, rehabilitation and long-term care
sub-acute units. Such units utilize less intensive staffing levels to provide
the range of services sought by payors with a lower cost structure.
 
    Tenet has acquired eight general hospitals (or interests in general
hospitals) since June 1, 1995, and currently has pending the acquisition of one
additional general hospital (pursuant to the North Shore Agreement). In July
1995, Tenet acquired a one-third interest (which subsequently was increased to a
50% interest) in the 82-bed St. Clair Hospital located outside of Birmingham,
Alabama, which formerly was a not-for-profit general hospital. In August 1995,
Tenet acquired Memorial Medical Center (formerly known as Mercy+Baptist Medical
Center), formerly a not-for-profit system, consisting of two general hospitals
with an aggregate of 759 licensed beds located in New Orleans, Louisiana, and
related physician practices. In September 1995, Tenet acquired Providence
Memorial Hospital located in El Paso, Texas, which also was a not-for profit
general hospital. Providence is licensed for 471 general hospital beds (34 of
which may be used as skilled nursing beds) and is licensed for 30 additional
rehabilitation and subacute care beds. In October 1995, Tenet entered into a
long-term lease of the 49-bed Medical Center of Manchester and its home health
business, in central Tennessee. In November 1995, Tenet acquired the 104-bed
Methodist Hospital of Jonesboro, a not-for-profit general hospital located in
Jonesboro, Arkansas. That hospital now is owned by a limited liability company
of which Tenet owns 95% and is the manager and Tenet's not-for profit partner
St. Vincent TotalHealth Corporation, owns 5%. In June 1996, Tenet acquired the
378-bed Hialeah Hospital in Hialeah, Florida. In October 1996, Tenet acquired
the 319-bed Lloyd Noland Hospital in Birmingham, Alabama. In the fourth quarter
of fiscal 1996, Tenet converted the Jo Ellen Smith general hospital in New
Orleans, Louisiana, into a specialty hospital. In November 1996, Tenet entered
into an agreement to acquire the 357-bed North Shore Medical Center in Miami,
Florida. See "Pro Forma Financial Information." In August 1995, Tenet entered
into an agreement with the Cleveland Clinic
 
                                       58
<PAGE>
Florida to develop a new 150-bed general hospital in western Broward County,
Florida. Completion of that project is subject to governmental approvals.
 
    During the same period, OrNda has completed the acquisition of six general
hospitals (or interests in general hospitals) and currently has pending the
acquisition of two additional general hospitals (pursuant to the United Western
Agreement). OrNda acquired Universal Medical Center (subsequently re-named
Florida Medical Center-South) in November 1995, a controlling equity interest in
Houston Northwest Medical Center in January 1996, Cypress Fairbanks Medical
Center and Westside Medical Center in July 1996, Centinela Hospital Medical
Center in August 1996 and The Saint Vincent Healthcare System in September 1996.
See "Pro Forma Financial Information."
 
    The Company also has been actively pursuing the acquisition and management
of physician practices and physician practice assets where doing so would
enhance the Company's goal of expanding and enhancing its integrated healthcare
delivery systems. During fiscal 1996, the Company acquired or assumed the
management of physician practices in many key geographic areas, such as Alabama,
Arkansas, southern California, South Carolina, south Florida, the greater New
Orleans, Louisiana area and Texas. Tenet also has established the Tenet
Physician Services department, based at its Dallas Operations Center, to plan
Tenet's strategy for and coordinate its efforts towards developing innovative
ways of working with physicians. The Company has developed and is continuing to
expand information systems for more efficiently managing all aspects of
physician practices, including billing, medical records, tracking managed care
contracts and accounting.
 
    During the last three fiscal years, Tenet and OrNda have spent an aggregate
of approximately $705.3 million and $222.2 million, respectively, on capital
expenditures at their domestic hospitals to expand and upgrade the facilities
and to acquire medical equipment. The Company expects to continue to make the
capital expenditures necessary to maintain and improve the Tenet and OrNda
facilities. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Tenet-- Liquidity and Capital Resources" and
"Management's Discussion and Analysis of Financial Condition and Results of

GEOGRAPHIC AREA DISCUSSION
 
    By providing Tenet with the opportunity to combine with a company having a
substantial portfolio of large, attractive urban and suburban hospitals known
for quality care and strong financial performance, the Merger supports a major
strategic objective of Tenet to reinforce its position as a significant provider
of healthcare services in selected geographic areas throughout the United States
and to enter new geographic areas attractive to Tenet such as Arizona and
Massachusetts. Tenet believes that the Merger will create a stronger, more
geographically diverse company that will be better able to grow through
strategic acquisitions and partnerships. The combined company will continue to
emphasize the creation of strong integrated healthcare delivery systems. The
Merger also expands the Company's operations into several new geographic areas,
including Arizona, Iowa, Massachusetts, Mississippi, Nevada, Oregon, Washington,
West Virginia and Wyoming. The following discussion summarizes the Company's
strategy in two of the principal geographic areas where the OrNda hospitals
being acquired pursuant to the Merger will complement Tenet's existing
integrated systems.
 
    SOUTHERN CALIFORNIA.  Southern California is geographically large and
densely populated. Los Angeles and Orange counties alone had a combined
population of over 11.3 million people in 1990 according to the United States
Bureau of the Census. For healthcare services companies, southern California is
a highly competitive environment characterized by an increasingly high degree of
managed care penetration.
 
    Tenet's strategy in southern California is to develop and expand its
integrated healthcare delivery system by combining its general hospitals and
related healthcare businesses with physicians, physician groups and ancillary
healthcare providers where appropriate in order to compete more effectively for
managed care contracts. Furthermore, Tenet intends to continue to join with
physicians and physician groups to form IPAs, PHOs or other appropriate
organizations that will enhance the ability of Tenet and its partners to enter
into additional managed care contracts, including capitated contracts under
which Tenet receives a fixed monthly payment per covered person in exchange for
which Tenet meets the healthcare needs of those covered by such contracts.
 
    The Merger provides Tenet with the opportunity to expand and enhance its
integrated healthcare delivery system by adding OrNda's 17 southern California
hospitals and related healthcare operations to Tenet's 15 existing hospitals and
related healthcare operations. Following the Merger, Tenet will be the largest
integrated healthcare provider in southern California and will have the widest
geographical representation in the area. Tenet's 31 general hospitals will
include three tertiary hospitals (Centinela Hospital Medical Center, Fountain
Valley Regional Hospital and Medical Center and Tarzana Regional Medical Center)
and one quartenary hospital (USC University Hospital), offering heart, liver and
lung transplants as well as gamma knife brain surgery. OrNda's pending
acquisition of the Western Medical Centers will add two additional hospitals to
the network, one of which is another tertiary care hospital.
 
    The table below sets forth, on a historical combined basis, certain selected
historical operating statistics for those hospitals operated by Tenet and OrNda
in the southern California area.

    SOUTH FLORIDA.  South Florida is a rapidly expanding metropolitan area that
encompasses Palm Beach, Broward and Dade counties. Those counties had a combined
population of approximately 4.1 million people in 1990 according to the United
States Bureau of the Census. The highly competitive south Florida healthcare
environment is characterized by an increasingly high degree of managed care
penetration.
 
    The Tenet South Florida HealthSystem is an integrated healthcare delivery
system that currently consists of seven general hospitals, four of which are
tertiary care hospitals, and numerous related healthcare operations, including a
physical rehabilitation facility, a psychiatric hospital, two skilled nursing
facilities, over 50 owned or managed physician practices and outpatient surgery,
diagnostic, workers' compensation occupational therapy and health and fitness
centers. The Merger will enhance Tenet's ability to compete for managed care and
other contracts by adding OrNda's four general hospitals, one of which is a
tertiary care hospital, and related healthcare businesses to the Tenet South
Florida HealthSystem and expanding the system's geographic reach further south
to Miami and Coral Gables. Tenet's pending acquisition of North Shore Medical
Center in Miami will further strengthen the network. Tenet intends to continue
to acquire or manage physician practices and to join with physicians and
physician groups to form IPAs, PHOs or other appropriate organizations that will
enhance the ability of Tenet and its partners to enter into more managed care
contracts, including capitated contracts.

in the south Florida area.

(1) For purposes of the above, financial and operating data for each of Tenet's
    fiscal years ended May 31 of the respective years has been combined with
    financial and operating data for each of OrNda's fiscal years ended August
    31 of such year.
 
OTHER DOMESTIC OPERATIONS
 
    At October 31, 1996, Tenet's subsidiaries owned or operated a small number
of rehabilitation hospitals, specialty hospitals, long-term care facilities and
psychiatric facilities as well as various ancillary healthcare businesses,
including outpatient surgery centers, home healthcare programs, ambulatory,
occupational and rural healthcare clinics, a health maintenance organization, a
preferred provider organization and a managed care insurance company. OrNda's
subsidiaries also own or operate extensive ancillary healthcare operations
similar to those of Tenet.
 
INVESTMENTS
 
    At October 31, 1996, Tenet held as investments (i) 8,301,067 shares of
Vencor, representing an approximately 12.1% interest in Vencor, which operates
nursing homes and other healthcare businesses, (ii) 3,000,000 shares of TRC,
representing an approximately 11.6% interest in TRC, which operates kidney
dialysis units and certain related healthcare businesses, and (iii) an
approximately 23% interest in HCPP, a partnership originally formed by the
Company and Health Care Property Investors, Inc. for the purpose of acquiring
from and leasing back to the Company 21 long-term care facilities, two general
hospitals and one psychiatric facility. Since that time, the Company has
assigned to Vencor (as successor to Hillhaven), and other third parties its
leasehold interests in the 21 long-term care facilities and the psychiatric
hospital, but remains contingently liable for the lease payments on those
facilities. The Company continues to lease the
 
                                       63
<PAGE>
two general hospitals from HCPP. HCPP does not own any properties other than
those originally purchased from the Company.
 
    In connection with the September 1995 merger transaction in which Vencor
acquired Hillhaven, Tenet received 8,301,067 shares of Vencor common stock in
exchange for its 8,878,147 shares of Hillhaven common stock. As part of that
transaction, Tenet also received approximately $91.8 million for the redemption
of its Hillhaven Series C Preferred Stock and Hillhaven Series D Preferred
Stock. In January 1996, Tenet sold $320 million principal amount of its 6%
Exchangeable Subordinated Notes due 2005, which Notes are exchangeable into
Tenet's 8,301,067 shares of Vencor common stock.
 
COMPETITION
 
    Tenet's general hospitals, rehabilitation hospitals, specialty hospitals,
long-term care facilities, psychiatric facilities, outpatient surgery centers
and other ancillary businesses operate in competitive environments. A facility's
competitive position within the geographic area in which it operates is affected
by such competitive factors as the quality of care provided, including the
number, quality and specialties of the physicians, nurses and other healthcare
professionals on staff, the quality of services provided by the hospital to
patients and their physicians, its reputation, the number of competitive
facilities, the state of its physical plant, the quality and the state of the
art of its medical equipment, its location and its charges for services.
Tax-exempt competitors may have certain financial advantages such as endowments,
charitable contributions, tax-exempt financing and exemption from sales,
property and income taxes not available to Tenet facilities. The length of time
a facility has been a part of the community and the availability of other
healthcare alternatives also are competitive factors.
 
    One factor of ever-increasing importance in the competitive position of
Tenet's facilities is the ability of those facilities to obtain managed care
contracts. The importance of obtaining managed care contracts has increased over
the years and is expected to continue to increase as employers, private and
government payors and others turn to the use of managed care in an attempt to
control rising healthcare costs. In fact, the revenues and operating results of
most of the Company's hospitals' are significantly affected by the hospitals'
ability to negotiate favorable contracts with managed care payors. Under such
contracts, healthcare providers agree to provide services on a discounted-fee or
capitated basis in exchange for the payors agreeing to send some or all of their
members/employees to those providers. With capitated contracts, a healthcare
provider such as Tenet receives specific fixed periodic payments from a health
maintenance organization, preferred provider organization or employer based on
the number of members of such organization being serviced by the provider. In
return, the provider agrees to provide healthcare services to such members
regardless of the actual costs incurred and services provided. A healthcare
provider's ability to compete for such contracts is affected by many factors,
such as the competitive factors referred to above, the scope, breadth and
quality of services a hospital offers in a given geographic area, its ability to
form its own, or to join with other healthcare providers to form, integrated
healthcare delivery systems and the scope, breadth and quality of services
offered by competing healthcare providers and/or systems. Tenet evaluates
changing circumstances in each geographic area on an ongoing basis and positions
itself to compete in the managed care market by forming its own or joining with
others to form integrated healthcare delivery systems, such as the Tenet South
Florida HealthSystem in South Florida, Sierra Providence Health Network in El
Paso, Texas and Tenet Louisiana HealthSystem in the greater New Orleans area,
that actively pursue and enter into managed care contracts. Tenet's integrated
healthcare delivery systems also compete for traditional fee-for-service
patients and contracts with traditional health insurers.
 
    The healthcare industry also has been characterized in recent years by
increased competition for patients and staff physicians, significant excess
capacity at general hospitals, a shift from inpatient to outpatient treatment
settings and increased consolidation. New competitive strategies of hospitals
and other healthcare providers place increasing emphasis on the use of
alternative healthcare delivery systems (such as home health services,
outpatient surgery and emergency and diagnostic centers) that eliminate or
reduce lengths of hospital stays. The principal factors contributing to these
trends are advances in medical
 
                                       64
<PAGE>
technology and pharmaceuticals, cost-containment efforts by managed care payors,
employers and traditional health insurers, changes in regulations and
reimbursement policies, increases in the number and type of competing healthcare
providers and changes in physician practice patterns. Tenet's future success
will depend, in part, on the ability of the Company's hospitals to continue to
attract and retain staff physicians, enter into managed care contracts and
organize and structure integrated healthcare delivery systems, including those
with other healthcare providers and physician practice groups.
 
    The Company's hospitals, and the healthcare industry as a whole, also face
the challenge of continuing to provide quality patient care while dealing with
strong competition for patients and with pressure on reimbursement rates not
only by private payors, but also by government payors. National and state
efforts to reform the United States healthcare system may further impact
reimbursement rates. Changes in medical technology, existing and future
legislation, regulations and interpretations and competitive contracting for
provider services by payors may require changes in the Company's facilities,
equipment, personnel, procedures, rates and/or services in the future.
 
    Inpatient admissions, average lengths of stay and average occupancy at
general hospitals, including the Company's general hospitals, continue to be
adversely affected by payor-required pre-admission authorization and utilization
review and payor pressure to maximize outpatient and alternative healthcare
delivery services for less acutely ill patients. Increased competition,
admissions constraints and payor pressures are expected to continue. Inpatient
acuity and intensity of services continue to increase as less intensive services
shift from an inpatient to an outpatient basis or to alternative healthcare
delivery services because of technological improvements and as payors continue
to limit or reduce payments. Those pressures imposed by government and private
payors and the increasing percentage of business negotiated with purchasers of
group healthcare services are expected to continue to put pressure on the
per-patient revenues received by the Company. To meet these challenges, the
Company (i) has expanded or converted many of its general hospitals' facilities
to include distinct outpatient centers, (ii) offers discounts to private payor
groups, (iii) enters into capitation contracts in some service areas, (iv)
upgrades facilities and equipment, (v) offers new programs and services, (vi)
has been reducing its costs, for example, through the implementation of a case
management system designed to maximize efficiency by identifying cost-per-
procedure variables among physicians performing the same procedures,
standardizing supplies used and negotiating volume discounts for purchases and
(vii) has developed a computerized outcomes management system that contains
clinical and demographic information from the Company's hospitals and physicians
and allows users to identify "best practices" for treating specific diagnostic
related groups. Nevertheless, there can be no assurance that these measures will
be successful or, if successful, will serve to compensate for the reduction in
inpatient admissions, average lengths of stay and average occupancy, and the
consequent reductions in per-patient revenue, resulting from the payor pressures
referred to above.
 
    As noted above, the Company also is responding to these changes by forming
integrated healthcare delivery systems. Components of these systems include: (i)
encouraging physicians practicing at its hospitals to form IPAs, (ii) having the
Company join with those IPAs, physicians and physician group practices to form
PHOs to contract with managed care and other payors and (iii) forming MSOs to
(A) purchase physician practices or their assets, as appropriate, (B) provide
management and administrative services to physicians, physician group practices
and IPAs and (C) enter into managed care contracts both on behalf of those
groups and, in certain circumstances, on behalf of PHOs.
 
    In large part, a hospital's revenues, whether from managed care payors,
traditional health insurance payors or directly from patients, depends on the
quality and scope of practices of physicians on staff. Physicians refer patients
to hospitals on the basis of the quality of services provided by the hospital to
patients and their physicians, the hospital's location, the quality of the
medical staff affiliated with the hospital and the quality and state of the art
of the hospital's facilities, equipment and employees. The Company attracts
physicians to its hospitals by equipping its hospitals with technologically
advanced equipment, sponsoring training programs to educate physicians on
advanced medical procedures, using governing boards for each hospital, the sole
voting members of which are physicians and community members, to develop short
and long-term plans for the hospital and review and approve, as appropriate,
actions of the medical staff, including staff appointments, credentialing, peer
review and quality assurance,
 
                                       65
<PAGE>
and otherwise creating an environment within which physicians prefer to
practice. While physicians may terminate their association with a hospital at
any time, Tenet believes that by striving to maintain and improve the level of
care at its hospitals and by maintaining ethical and professional standards, it
will attract and retain qualified physicians with a variety of specialties.
 
    There has been significant consolidation in the hospital industry over the
past decade due, in large part, to continuing pressures on payments from
government and private payors and increasing shifts away from the provision of
traditional in-patient services. Those economic trends have caused many
hospitals to close and many to consolidate either through acquisitions or
affiliations. Tenet's management believes that these cost-containment pressures
will continue and will lead to further consolidation in the hospital industry.
 
    Tenet and its hospitals strive, on terms favorable to the Company, to
attract and retain physicians to their staffs, enter into managed care
contracts, organize and structure integrated healthcare delivery systems,
organize and structure integrated healthcare delivery systems, acquire hospitals
or other healthcare facilities and acquire or assume the management of physician
practices. Other healthcare companies with greater financial resources, with
more facilities in a given geographic area or offering a wider range of services
may be competing in each of these areas. These competitive factors may result in
Tenet and its hospitals being less successful than they would hope to be in
accomplishing one or more of these goals.
 
MEDICARE, MEDICAID AND OTHER REVENUES
 
    Tenet receives payments for patient care from private insurance carriers,
Federal Medicare programs for elderly and disabled patients, HMOs, preferred
provider organizations ("PPOs"), state Medicaid programs for indigent and cash
grant patients, the Civilian Health and Medical Program of the Uniformed
Services ("CHAMPUS"), employers and patients directly. In general, Medicare
payments for general hospital outpatient services, psychiatric care, physical
rehabilitation and nursing home care are based on the lower of charges and
allowable costs, subject to certain limits. General hospital inpatient services
are reimbursed under Medicare based on a prospective payment system, discussed
below. Payments from state Medicaid programs are based on reasonable costs or
are at fixed rates. Substantially all Medicare and Medicaid payments are below
retail rates for Tenet facilities. Payments from other sources usually are based
on the hospital's established charges, a percentage discount or all-inclusive
per diem rates.
 
    The approximate percentages of Tenet's net patient revenue by payment
sources for Tenet's general hospitals are as follows:

    Medicare payments for general hospital inpatient care are based on a
prospective payment system ("PPS") that generally has been applicable to Tenet's
facilities since 1984. Under the PPS, a general hospital receives for each
Medicare patient a fixed amount for operating costs based on each Medicare
patient's assigned diagnostic related group ("DRG"). DRG payments do not
consider a specific hospital's costs, but are adjusted for area wage
differentials. As discussed below, DRG payments exclude the reimbursement of (a)
capital costs, including depreciation, interest relating to capital
expenditures, property tax and lease expenses and (b) outpatient services.
 
    For several years the percentage increases to the DRG rates have been lower
than the percentage increases in the cost of goods and services purchased by
general hospitals. The index used by the Health Care Financing Administration to
adjust the DRG rates gives consideration to the cost of goods and services
purchased by hospitals as well as non-hospitals (the "Market Basket"). The
increase in the Market Basket for the year beginning October 1, 1996, was 2.5%.
The Omnibus Budget Reconciliation Act of 1993 ("OBRA '93") provides that the DRG
rates for urban hospitals will be adjusted by the annual Market Basket
percentage change: (1) minus 2.5%, effective October 1, 1994, (2) minus 2.0%,
effective October 1, 1995, (3) minus .5%, effective October 1, 1996, and (4)
without reduction, effective October 1, 1997 and each year thereafter, unless
altered by subsequent legislation (which legislation Tenet believes has become
more likely in light of the stated desire of both the current Administration and
Congress to balance the Federal budget). There was an increase of 2.0% in the
DRG rates for Federal fiscal year 1997 over what they were for Federal fiscal
year 1996. Congress is in the process of establishing the healthcare budget for
future periods, including Federal fiscal year 1997. Tenet anticipates that
payments to hospitals will be reduced as a result of future legislation but is
unable to predict what the amount of the final reduction will be.
 
    Medicare reimburses general hospitals' capital costs separately from DRG
payments. Beginning in 1992, a prospective payment system for Medicare
reimbursement of general hospitals' inpatient capital costs ("PPS-CC") generally
became effective with respect to the Company's general hospitals. During Tenet's
fiscal year ended May 31, 1996, Tenet's hospitals in the aggregate received
reimbursement for approximately 95% of their actual capital costs under the
PPS-CC. Tenet anticipates that future legislation may reduce the aggregate
reimbursement received, but is unable to predict what the amount of the final
reduction will be.
 
    Outpatient services provided at general hospitals, physical rehabilitation
hospitals and psychiatric facilities generally are reimbursed by Medicare at the
lower of customary charges or 94.2% of actual cost. Notwithstanding the
foregoing, Congress has established additional limits on the reimbursement of
the following outpatient services: (i) clinical laboratory services, which are
reimbursed based on a fee schedule and (ii) ambulatory surgery procedures and
certain imaging and other diagnostic procedures, which are reimbursed based on a
blend of the hospital's specific cost and the rate paid by Medicare to
non-hospital providers for such services.
 
    Hospitals exempt from the PPS, such as qualified psychiatric facilities and
physical rehabilitation hospitals, are reimbursed by Medicare on a cost-based
system wherein target rates for each facility are used in applying various
limitations and incentives. Tenet's exempt facilities received a Market Basket
increase of 3.4% in target rates effective for cost reporting periods commencing
in Federal fiscal year 1996. Based on OBRA '93, the target rates for Tenet's
hospitals exempt from the PPS will be adjusted in cost reporting years through
1997 by the applicable annual Market Basket percentage change minus 1%.
Proposals have been made that would change the method of payment for services
provided at these facilities to a prospective payment system. The Omnibus Budget
Reconciliation Act of 1990 requires the Department of Health and Human Services
to develop a proposal to modify the current target rate system or to replace it
with a prospective payment system. It is not known if any such proposals will be
implemented.
 
    OBRA '93 provides for certain budget targets through Federal fiscal year
1997, which, if not met, may result in adjustments in payment rates. Both
Congress and the current Administration have proposed
 
                                       67
<PAGE>
healthcare budgets that reduce Federal payments to hospitals and other
providers. The Company anticipates that payments to hospitals will be reduced as
a result of future legislation but is unable to predict what the amount of the
final reduction will be.
 
    The Medicare, Medicaid and CHAMPUS programs are subject to statutory and
regulatory changes, administrative rulings, interpretations and determinations,
requirements for utilization review and new governmental funding restrictions,
all of which may materially increase or decrease program payments as well as
affect the cost of providing services and the timing of payments to facilities.
The final determination of amounts earned under the programs often requires many
years, because of audits by the program representatives, providers' rights of
appeal and the application of numerous technical reimbursement provisions.
Management believes that adequate provision has been made for such adjustments.
Until final adjustment, however, significant issues remain unresolved and
previously determined allowances could become either inadequate or more than
ultimately required.
 
HEALTHCARE REFORM, REGULATION AND LICENSING
 
    CERTAIN BACKGROUND INFORMATION.  Healthcare, as one of the largest
industries in the United States, continues to attract much legislative interest
and public attention. Medicare, Medicaid, mandatory and other public and private
hospital cost-containment programs, proposals to limit healthcare spending,
proposals to limit prices and industry competitive factors are highly
significant to the healthcare industry. In addition, the healthcare industry is
governed by a framework of Federal and state laws, rules and regulations that
are extremely complex and for which the industry has the benefit of little or no
regulatory or judicial interpretation. Although the Company believes it is in
compliance in all material respects with such laws, rules and regulations, if a
determination is made that the Company was in material violation of such laws,
rules or regulations, its operations and financial results could be materially
adversely affected.
 
    There continue to be Federal and state proposals that would, and actions
that do, impose more limitations on government and private payments to providers
such as Tenet and proposals to increase co-payments and deductibles from program
and private patients. Tenet's and OrNda's facilities also are affected by
controls imposed by government and private payors designed to reduce admissions
and lengths of stay. Such controls, including what is commonly referred to as
"utilization review," have resulted in fewer of certain treatments and
procedures being performed. Utilization review entails the review of the
admission and course of treatment of a patient by a third party. Utilization
review by third-party peer review organizations ("PROs") is required in
connection with the provision of care paid for by Medicare and Medicaid.
Utilization review by third parties also is a requirement of many managed care
arrangements.
 
    Many states have enacted or are considering enacting measures that are
designed to reduce their Medicaid expenditures and to make certain changes to
private healthcare insurance. Various states have applied, or are considering
applying, for a Federal waiver from current Medicaid regulations to allow them
to serve some of their Medicaid participants through managed care providers.
Tennessee has implemented a revision and Texas has passed a law mandating the
State to apply for such a waiver. Louisiana is considering wider use of managed
care for its Medicaid populations. California has created a voluntary health
insurance purchasing cooperative that seeks to make healthcare coverage more
affordable for businesses with five to 50 employees and, effective January 1,
1995, began changing the payment system for participants in its Medicaid program
in certain counties from fee-for-service arrangements to managed care plans.
Florida limits the amount by which a hospital's net revenues per admission may
be increased each year, has enacted a program creating a system of local
purchasing cooperatives and has proposed other changes that have not yet been
enacted. Florida also has adopted, and other states are considering adopting,
legislation imposing a tax on revenues of hospitals to help finance or expand
those states' Medicaid systems. A number of other states are considering the
enactment of managed care initiatives designed to provide universal low-cost
coverage. These proposals also may attempt to include coverage for some people
who presently are uninsured.
 
                                       68
<PAGE>
    CERTIFICATE OF NEED REQUIREMENTS.  Some states require state approval for
construction and expansion of healthcare facilities, including findings of need
for additional or expanded healthcare facilities or services. Certificates of
Need, which are issued by governmental agencies with jurisdiction over
healthcare facilities, are at times required for capital expenditures exceeding
a prescribed amount, changes in bed capacity or services and certain other
matters. Following a number of years of decline, the number of states requiring
Certificates of Need is once again on the rise as state legislators once again
are looking at the Certificate of Need process as a way to contain rising
healthcare costs. At November 30, 1996, Tenet operated hospitals in 11 states
and OrNda operated hospitals in seven additional states that require state
approval under Certificate of Need Programs. Tenet is unable to predict whether
it will be able to obtain any Certificates of Need in any jurisdiction where
such Certificates of Need are required.
 
    ANTIKICKBACK AND SELF-REFERRAL REGULATIONS.  The healthcare industry is
subject to extensive Federal, state and local regulation relating to licensure,
conduct of operations, ownership of facilities, addition of facilities and
services and prices for services. In particular, the Antikickback Amendments
prohibit certain business practices and relationships that might affect the
provision and cost of healthcare services reimbursable under Medicare and
Medicaid, including the payment or receipt of remuneration for the referral of
patients whose care will be paid for by Medicare or other government programs.
Sanctions for violating the Antikickback Amendments include criminal penalties
and civil sanctions, including fines and possible exclusion from government
programs such as the Medicare and Medicaid programs. Pursuant to the Medicare
and Medicaid Patient and Program Protection Act of 1987, HHS has issued
regulations that describe Safe Harbors under the Antikickback Amendments. The
fact that a given business arrangement does not fall within a Safe Harbor does
not render the arrangement PER SE illegal. Business arrangements of healthcare
service providers that fail to satisfy the applicable Safe Harbor criteria,
however, risk increased scrutiny by enforcement authorities. Because Tenet may
be less willing than some of its competitors to enter into business arrangements
that do not clearly satisfy the Safe Harbors, it could be at a competitive
disadvantage in entering into certain transactions and arrangements with
physicians and other healthcare providers.
 
    The "Health Insurance Portability and Accountability Act of 1996," which
becomes effective January 1, 1997, amends, among other things, Title XI (42
U.S.C. 1301 ET SEQ.) to broaden the scope of current fraud and abuse laws to
include all health plans, whether or not they are reimbursed as a Federal
program.
 
    In addition, Section 1877 of the Social Security Act, which restricts
referrals by physicians of Medicare and other government-program patients to
providers of a broad range of designated health services with which they have
ownership or certain other financial arrangements, was amended effective January
1, 1995, to significantly broaden the scope of prohibited physician referrals
under the Medicare and Medicaid programs to providers with which they have
ownership or certain other financial arrangements. Many states have adopted or
are considering similar legislative proposals, some of which extend beyond the
Medicaid program to prohibit the payment or receipt of remuneration for the
referral of patients and physician self-referrals regardless of the source of
the payment for the care. Tenet's participation in and development of joint
ventures and other financial relationships with physicians could be adversely
affected by these amendments and similar state enactments. The Company
systematically reviews all of its operations to ensure that it complies with the
Social Security Act and similar state statutes.
 
    Both Federal and state government agencies have announced heightened and
coordinated civil and criminal enforcement efforts. One pilot project, Operation
Restore Trust, is focused on investigating healthcare providers in the home
health and nursing home industries as well as on medical suppliers to these
providers in California, Florida, Texas, Illinois and New York. The Company
provides home health and nursing home care in California, Florida and Texas.
 
    Tenet is unable to predict the future course of Federal, state and local
regulation or legislation, including Medicare and Medicaid statutes and
regulations. Further changes in the regulatory framework could have a material
adverse effect on Tenet's business, financial condition and results of
operations.
 
    ENVIRONMENTAL REGULATIONS.  The Company's healthcare operations generate
medical waste that must be disposed of in compliance with Federal, state and
local environmental laws, rules and regulations. The
 
                                       69
<PAGE>
Company's operations, as well as the Company's purchases and sales of
facilities, are also subject to compliance with various other environmental
laws, rules and regulations. Such compliance does not, and the Company
anticipates that such compliance will not, materially affect the Company's
capital expenditures, earnings or competitive position.
 
    HEALTHCARE FACILITY LICENSING REQUIREMENTS.  Tenet's healthcare facilities
are subject to extensive Federal, state and local legislation and regulation. In
order to maintain their operating licenses, healthcare facilities must comply
with strict standards concerning medical care, equipment and hygiene. Various
licenses and permits also are required in order to dispense narcotics, operate
pharmacies, handle radioactive materials and operate certain equipment. Tenet's
healthcare facilities hold all required governmental approvals, licenses and
permits. With the exception of one general hospital that has not sought to be
accredited, each of Tenet's facilities that is eligible for accreditation is
fully accredited by the JCAHO, the Commission on Accreditation of Rehabilitation
Facilities (in the case of rehabilitation hospitals) or another appropriate
accreditation agency. With such accreditation, the Company's hospitals are
eligible to participate in government-sponsored provider programs such as the
Medicare and Medicaid programs.
 
    UTILIZATION REVIEW COMPLIANCE AND HOSPITAL GOVERNANCE.  Tenet's healthcare
facilities are subject to and comply with various forms of utilization review.
In addition, under the Medicare PPS, each state must have a PRO to carry out a
federally mandated system of review of Medicare patient admissions, treatments
and discharges in general hospitals. Medical and surgical services and practices
are extensively supervised by committees of staff doctors at each healthcare
facility, are overseen by each healthcare facility's local governing board,
comprised of healthcare professionals, community members and hospital
representatives, and are reviewed by Tenet's quality assurance personnel. The
local governing boards also help maintain standards for quality care, develop
long-range plans, establish, review and enforce practices and procedures and
approve the credentials and disciplining of medical staff members.
 
LEGAL PROCEEDINGS
 
    The Company continues to defend a greater than normal level of litigation
relating to its subsidiaries' former psychiatric operations. The majority of the
lawsuits filed contain allegations of medical malpractice as well as allegations
of fraud and conspiracy against the Company and certain of its subsidiaries and
former employees. Also named as defendants are numerous doctors and other
healthcare professionals. The Company believes that the increase in litigation
stems, in whole or in part, from advertisements by certain lawyers seeking
former psychiatric patients in order to file claims against the Company and
certain of its subsidiaries. The advertisements focus, in many instances, on the
Company's settlement of past disputes involving the operations of its
discontinued psychiatric business, including the Company's 1994 resolution of
the Federal government's investigation and a corresponding criminal plea
agreement involving such discontinued psychiatric business of the Company. Among
the suits filed during fiscal 1995 were two lawsuits in Texas state court with
approximately 740 individual plaintiffs at present who purport to have been
patients in certain Texas psychiatric facilities. During fiscal 1996, 64
plaintiffs voluntarily withdrew from one of the lawsuits and the Company's
motion to recuse the original trial judge in that lawsuit has been granted. In
the second lawsuit, the Texas Supreme Court has ruled that lead counsel for the
plaintiffs may not continue to represent the plaintiffs due to a conflict of
interest as asserted by the defendants. The cases of three of the 740 individual
plaintiffs within one of the lawsuits currently are scheduled for trial in April
1997.
 
    During fiscal 1995 and 1996, lawsuits with approximately 210 plaintiffs at
present who purport to have been patients in certain Washington, D.C.
psychiatric facilities, containing allegations similar to those contained in the
Texas cases described above, were filed in the District of Columbia.
 
    In addition to the above, a purported class action was filed in Texas state
court in May 1995, entitled Justin Love vs. National Medical Enterprises, et al.
The case contains allegations of fraud and conspiracy similar to those described
in the preceding paragraphs. The plaintiff purports to represent all persons who
were voluntarily admitted to one of 11 psychiatric hospitals in Texas between
January 1, 1981 and December 31, 1991, and who also fit into one or more of
eight categories based on such factors as their age
 
                                       70
<PAGE>
at the time of admission, status of their insurance at the time of discharge and
whether a certain type of examination was conducted prior to their being
admitted. In February 1996, an insurance company that purports to have paid
claims on behalf of the potential class intervened in the action and the case
was removed to the U.S. District Court in Houston, Texas. A motion by the
plaintiffs to remand the case to Texas state court currently is pending. A class
has not been certified and the Company believes that a class is not capable of
being certified.
 
    The Company expects that additional lawsuits with similar allegations will
be filed. The Company believes it has a number of defenses to each of these
actions and will defend these and any additional lawsuits vigorously. Until the
lawsuits are resolved, however, the Company will continue to incur substantial
legal expenses. Although, based upon information currently available to it,
management believes that the amount of damages, if any, in excess of the
reserves the Company has recorded for unusual litigation costs that may be
awarded in any of the foregoing unresolved legal proceedings cannot reasonably
be estimated, management does not believe it is likely that any such damages
will have a material adverse effect on the Company's results of operations,
liquidity or capital resources. There can be no assurance, however, that the
ultimate liability will not exceed such reserves, which primarily represent the
estimated costs of defending the actions.
 
    Two additional federal class actions filed in August 1993 were consolidated
into one action pending in the U.S. District Court in the Central District of
California captioned In re: National Medical Enterprises Securities Litigation
II. These consolidated actions are on behalf of a purported class of
shareholders who purchased or sold stock of the Company between January 14, 1993
and August 26, 1993, and allege that each of the defendants violated Section
10(b) of the Exchange Act. Specifically, plaintiffs allege that each defendant
knew or recklessly disregarded that the public statements made by the Company
and several of its officers and directors in reports filed with the Commission,
in press releases, communications with shareholders, and communications with the
financial community were false and misleading because the financial data and
projections were based upon a number of alleged illegal practices at many of the
Company's psychiatric facilities. Plaintiffs claim that each of the defendants
was a direct participant in this wrongdoing and conspired with and aided and
abetted each of the other defendants in perpetrating the alleged fraudulent
scheme. Based on these claims, plaintiffs seek compensatory damages, injunctive
relief, attorneys' fees, interest and costs. The parties commenced a voluntary
mediation in July 1994. The mediation efforts were unsuccessful and in May 1995
the parties agreed to proceed with the litigation. On June 23, 1995, the
defendants filed a motion to dismiss and to strike plaintiffs' complaint, which
motion is still pending. The Company believes it has meritorious defenses to
this action and will defend this litigation vigorously.
 
    In connection with the merger of AMH with and into a subsidiary of Tenet in
March 1995, a total of nine purported class actions, entitled in re: American
Medical Holdings, Inc., Shareholders Litigation, C.A. No. 13797, Ruth LeWinter
and Raymond Cayuso v. the AMH Directors (with the exception of Harold S.
Williams), NME and AMH, Case No. BC-115206, and David F. and Sylvia Goldstein v.
O'Leary, NME, AMH, et al., Case No. BC-116104 (the "Merger Class Actions"), were
filed challenging the AMH Merger in both Delaware and California. In April 1996,
the parties to the Merger Class Actions executed a stipulation of settlement and
in August 1996 the court issued an order approving the settlement. Under the
terms of that settlement, the Company agreed to pay $350,000 for the plaintiffs'
attorneys fees and agreed that for a period of one year following final approval
of the settlement it will not engage in any transaction that will be dilutive to
existing shareholders without that transaction being approved by a majority of
its outside directors. Tenet believes the Merger with OrNda will not be dilutive
after taking into account the cost savings that management believes may be
realized following the Merger. Nevertheless, the Merger has been approved by the
required majority of Tenet's outside directors.
 
    In February 1996, OrNda's Midway Hospital Medical Center in Los Angeles,
California, which was acquired from Summit in April 1994, received an
investigative subpoena from the OIG. The subpoena states that it was issued in
connection with an investigation being conducted by the OIG concerning possible
violations of Medicare rules and regulations. OrNda has been advised that the
investigation is in connection with a civil investigation under the direction of
the Civil Division of the Department of Justice.
 
                                       71
<PAGE>
OrNda is fully cooperating with the government investigation. In June 1996, the
government expanded this civil investigation to arrangements between physicians
and the remaining eleven hospitals which OrNda acquired from Summit in 1994.
Also, in an apparently unrelated matter, the government has requested and OrNda
has agreed to provide similar records from a single hospital outside the group
acquired from Summit in 1994. Tenet understands that OrNda and its outside
counsel have held numerous meetings with the governmental attorneys in respect
of this matter and, as a result, OrNda believes that at this time this
investigation is focused primarily on its hospitals' physician arrangements and
not the hospitals' Medicare or Medicaid billing practices. Although no
proceedings have been instituted, in the event that the OIG believes that any
wrongdoing has occurred, civil and possibly criminal proceedings could be
instituted. If any such proceedings were instituted and the outcome were
unfavorable, OrNda could be subject to fines, penalties and damages and also
could be excluded from Medicare and other government reimbursement programs. The
aggregate amount of such fines, penalties and damages and any such exclusion
could have a material adverse effect on OrNda's financial position or results of
operations. The results of this investigation and its impact, if any, cannot be
predicted or estimated at this time. Tenet understands that, based on
information currently available to OrNda, management of OrNda believes that if
the investigation remains limited to physician arrangements, remains civil in
nature and, with the single exception noted above, relates only to the practices
of the hospitals of an acquired corporation, the final outcome of this
investigation will not have a material adverse effect on OrNda's financial
position or results of operations. If any of the foregoing matters was to have a
material adverse effect on OrNda, it could also have a material adverse effect
on Tenet's business, financial condition and results of operations following the
Merger.
 
    In its normal course of business the Company also is subject to claims and
lawsuits relating to injuries arising from patient treatment. The Company
believes that its liability for damages resulting from such claims and lawsuits
in its normal course of business is adequately covered by insurance or is
adequately provided for in its consolidated financial statements. See "Risk
Factors--Legal Proceedings."
 
COMPLIANCE PROGRAM
 
    The Company maintains a multi-faceted corporate compliance and ethics
program. A portion of the program results from a 1994 settlement between the
Company and HHS. The mandated portion of the program, which is in effect until
June 1999, provides, in part, that the Company will not own or operate
psychiatric facilities (defined for the purposes of the agreement to include
residential treatment centers and substance abuse facilities) except as
specifically provided for under the terms of the agreement (which permits the
Company's subsidiaries to own and operate a small number of psychiatric
facilities on the same campus as or nearby certain of Tenet's general hospitals)
and requires self-reporting of credible evidence of violations of criminal law
or material violations of civil laws, rules or regulations governing federally
funded programs. The Company now has in place a program designed to provide
annual ethics training to every employee and to encourage all employees to
report any ethical violations to a toll-free telephone hotline.

                              DESCRIPTION OF NOTES
 
GENERAL
 
    The Senior Notes will be issued pursuant to an Indenture (the "Senior Note
Indenture") between the Company and The Bank of New York, as Trustee (the
"Senior Note Trustee"). The Senior Subordinated Notes will be issued pursuant to
an Indenture (the "Senior Subordinated Note Indenture" and, together with the
Senior Note Indenture, the "Indentures") between the Company and The Bank of New
York, as Trustee (the "Senior Subordinated Note Trustee" and, together with the
Senior Note Trustee, the "Trustees"). The terms of the Notes include those
stated in the Indentures and those made part of the Indentures by reference to
the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The
Notes are subject to all such terms, and Holders of Notes are referred to the
Indentures and the Trust Indenture Act for a statement thereof. The following
summary of certain provisions of the Indentures does not purport to be complete
and is qualified in its entirety by reference to the Indentures, including the
definitions therein of certain terms used below. Copies of the proposed forms of
Indentures have been filed as exhibits to the Registration Statement of which
this Prospectus is a part. The definitions of certain terms used in the
following summary are set forth below under "--Certain Definitions." As used in
this "Description of Notes," the term the "Company" refers to Tenet Healthcare
Corporation and not to any of its Subsidiaries.
 
    The Senior Notes will be general unsecured obligations of the Company,
senior to all subordinated Indebtedness of the Company, including the Senior
Subordinated Notes, the Company's 10 1/8% Senior Subordinated Notes due 2005
(the "2005 Senior Subordinated Notes") and the Company's 6% Exchangeable
Subordinated Notes due 2005 (the "2005 Exchangeable Subordinated Notes"), and
PARI PASSU in right of payment with all other existing and future unsubordinated
Indebtedness of the Company, including the Company's 9 5/8% Senior Notes due
2002 (the "2002 Senior Notes"), the Company's 8 5/8% Senior Notes due 2003 (the
"2003 Notes" and, together with the 2002 Senior Notes, the "Existing Senior
Notes") and all Obligations under the New Credit Facility. On a pro forma basis,
as of November 30, 1996, after giving effect to the Merger and the Refinancing,
approximately $   billion in principal amount of outstanding indebtedness of the
Company will by its terms be subordinated to the Senior Notes.
 
    The Senior Subordinated Notes will be general unsecured obligations of the
Company, subordinated in right of payment to all existing and future Senior Debt
of the Company, including the Senior Notes, the Existing Senior Notes and all
Obligations under the New Credit Facility, and will be PARI PASSU in right of
payment to the 2005 Senior Subordinated Notes and senior to the 2005
Exchangeable Subordinated Notes. On a pro forma basis, as of November 30, 1996,
after giving effect to the Merger and the Refinancing, Senior Debt of the
Company would have been approximately $   billion. See "Historical and Pro Forma
Capitalization," "Related Transactions," "Description of the New Credit
Facility" and "--Subordination of Senior Subordinated Notes."
 
    The operations of the Company are conducted through its Subsidiaries and,
therefore, the Company is dependent upon the cash flow of its Subsidiaries to
meet its obligations, including its obligations under the Notes. The Notes will
be effectively subordinated to all outstanding Indebtedness and other
liabilities and commitments (including trade payables and lease obligations) of
the Company's Subsidiaries. Any right of the Company to receive assets of any of
its Subsidiaries upon the latter's liquidation or reorganization or insolvency
(and the consequent right of the Holders of Notes to participate in those
assets) will be effectively subordinated to the claims of that Subsidiary's
creditors and preferred stockholders, except to the extent that the Company is
itself recognized as a creditor of such Subsidiary, in which case the claims of
the Company would still be subordinate to any security interest in the assets of
such Subsidiary and any Indebtedness of such Subsidiary senior to that held by
the Company. On a pro forma basis, as of November 30, 1996, after giving effect
to the Merger and the Refinancing, the outstanding Indebtedness and other
obligations of the Company's Subsidiaries would have been approximately $
billion (based upon certain assumptions as to the amounts of indebtedness of
OrNda to be redeemed or repurchased and excluding trade payables of $   million
and intercompany Indebtedness). See "Risk Factors--Subsidiary Operations;
Subordination" and "Pro Forma Financial Information."

comprised of twelve 30-day months. Principal, premium, if any, and interest on
the Notes will be payable at the office or agency of the Company maintained for
such purpose within the City and State of New York or, at the option of the
Company, payment of interest may be made by check mailed to the Holders of the
Notes at their respective addresses set forth in the register of Holders of
Notes; provided that all payments with respect to Notes, the Holders of which
have given wire transfer instructions, on or prior to the relevant record date,
to the paying agent, will be required to be made by wire transfer of immediately
available funds to the accounts specified by such Holders. Until otherwise
designated by the Company, the Company's office or agency in New York will be
the office of the applicable Trustee maintained for such purpose. The Notes will
be issued in denominations of $1,000 and integral multiples thereof.

    If less than all of the Senior Subordinated Notes are to be redeemed at any
time, selection of Senior Subordinated Notes for redemption will be made by the
applicable Trustee in compliance with the requirements of the principal national
securities exchange, if any, on which the Senior Subordinated Notes are then

Senior Subordinated Note in
 
                                       77
<PAGE>
principal amount equal to the unredeemed portion thereof will be issued in the
name of the Holder thereof upon cancellation of the original Senior Subordinated
Note. On and after the redemption date, interest will cease to accrue on Senior
Subordinated Notes or portions of them called for redemption.
 
    The New Credit Facility will prohibit the Company from redeeming or

MANDATORY REDEMPTION
 
    Except as set forth below under "--Repurchase at the Option of Holders," the
Company will not be required to make any mandatory redemption or sinking fund
payments with respect to the Notes.
 
REPURCHASE AT THE OPTION OF HOLDERS UPON A CHANGE OF CONTROL
 
    Upon the occurrence of a Change of Control Triggering Event, each Holder of
Notes will have the right to require the Company to repurchase all or any part
(equal to $1,000 or an integral multiple thereof) of such Holder's Notes
pursuant to the offer described below (the "Change of Control Offer") at an
offer price in cash equal to 101% of the aggregate principal amount thereof plus
accrued and unpaid interest thereon to the date of purchase (the "Change of
Control Payment") on a date that is not more than 90 days after the occurrence
of such Change of Control Triggering Event (the "Change of Control Payment
Date"). Within 30 days following any Change of Control Triggering Event, the
Company will mail, or at the Company's request the applicable Trustee will mail,
a notice to each Holder offering to repurchase the Notes held by such Holder
pursuant to the procedures specified in such notice. The Company will comply
with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of the Notes as a
result of a Change of Control Triggering Event.
 
    On the Change of Control Payment Date, the Company will, to the extent
lawful, (1) accept for payment all Notes or portions thereof properly tendered
and not withdrawn pursuant to the Change of Control Offer, (2) deposit with the
paying agent an amount equal to the Change of Control Payment in respect of all
Notes or portions thereof so tendered and (3) deliver or cause to be delivered
to the applicable Trustee the Notes so accepted together with an Officers'
Certificate stating the aggregate principal amount of Notes or portions thereof
being purchased by the Company. The paying agent will promptly mail to each
Holder of Notes so tendered the Change of Control Payment for such Notes, and
the applicable Trustee will promptly authenticate and mail (or cause to be
transferred by book entry) to each Holder a new Note equal in principal amount
to any unpurchased portion of the Notes surrendered, if any; provided that each
such new Note will be in a principal amount of $1,000 or an integral multiple
thereof. The Senior Subordinated Note Indenture will provide that, prior to
complying with the provisions of this covenant, but in any event within 90 days
following a Change of Control Triggering Event, the Company will either repay
all outstanding Senior Debt or obtain the requisite consents, if any, under all
agreements governing outstanding Senior Debt to permit the repurchase of Senior
Subordinated Notes required by this covenant. The Company will publicly announce
the results of the Change of Control Offer on or as soon as practicable after
the Change of Control Payment Date.
 
    A failure by the Company to comply with the provisions of the two preceding
paragraphs will constitute an Event of Default under the applicable Indenture.
Except as described above with respect to a Change of Control, the Indentures
will not contain provisions that permit the Holders of the Notes to require that
the Company purchase or redeem the Notes in the event of a takeover,
recapitalization or similar transaction. See "--Events of Default and Remedies."
 
    The New Credit Facility will prohibit the Company from redeeming or
otherwise repurchasing the Senior Subordinated Notes prior to the stated
maturity thereof, and also will provide that certain change of control events
with respect to the Company will constitute a default thereunder. See
"Description of the New Credit Facility." Any future credit agreements or other
agreements relating to Senior Debt to which the Company becomes a party may
contain similar restrictions and provisions. The indentures relating to
 
                                       78
<PAGE>
the Existing Senior Notes may restrict the Company's ability to purchase the
Senior Subordinated Notes upon a Change of Control Triggering Event. In the
event a Change of Control occurs at a time when the Company is prohibited from
purchasing the Senior Subordinated Notes, the Company could seek the consent of
its lenders or noteholders to the purchase of the Senior Subordinated Notes or
could attempt to refinance the Indebtedness that contains such prohibition. If
the Company does not obtain such a consent or repay such Indebtedness, the
Company will remain prohibited from purchasing the Senior Subordinated Notes. In
such case, the Company's failure to purchase tendered Senior Subordinated Notes
would constitute an Event of Default under the Senior Subordinated Notes
Indenture which could, in turn, constitute a default under other outstanding
Indebtedness. In such circumstances, the subordination provisions in the Senior
Subordinated Note Indenture would likely restrict payments to the Holders of
Senior Subordinated Notes. See "Risk Factors--Possible Inability to Repurchase
Notes Upon a Change of Control" and "--Subsidiary Operations; Subordination."
 
SUBORDINATION OF SENIOR SUBORDINATED NOTES
 
    The payment of principal of, premium, if any, and interest on the Senior
Subordinated Notes will be subordinated in right of payment, as set forth in the
Senior Subordinated Note Indenture, to the prior payment in full of all Senior
Debt, whether outstanding on the date of the Senior Subordinated Note Indenture
or thereafter incurred.
 
    Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property, an
assignment for the benefit of creditors or any marshalling of the Company's
assets and liabilities, the holders of Senior Debt will be entitled to receive
payment in full of all Obligations due in respect of such Senior Debt (including
interest accruing after the commencement of any such proceeding at the rate
specified in the applicable Senior Debt, whether or not allowed or allowable as
a claim in such proceeding) before the Holders of Senior Subordinated Notes will
be entitled to receive any payment with respect to the Senior Subordinated
Notes, and until all Obligations with respect to Senior Debt are paid in full,
any distribution to which the Holders of Senior Subordinated Notes would be
entitled shall be made to the holders of Senior Debt (except (a) that Holders of
Senior Subordinated Notes may receive securities that (i) are subordinated at
least to the same extent as the Senior Subordinated Notes to Senior Debt and any
securities issued in exchange for Senior Debt, (ii) are unsecured (except to the
extent the Senior Subordinated Notes are secured), (iii) are not Guaranteed by
any Subsidiary of the Company (except to the extent the Senior Subordinated
Notes are so Guaranteed), and (iv) have a Weighted Average Life to Maturity and
final maturity that are not shorter than the Weighted Average Life to Maturity
of the Senior Subordinated Notes or any securities issued to holders of Senior
Debt under the New Credit Facility pursuant to a plan of reorganization or
readjustment, and (b) payments made from the trust described under "--Legal
Defeasance and Covenant Defeasance").
 
    The Company also may not make any payment upon or in respect of the Senior
Subordinated Notes (except in such subordinated securities or from the trust
described under "--Legal Defeasance and Covenant Defeasance") if (i) a default
in the payment of the principal of, premium, if any, or interest on Designated
Senior Debt occurs and is continuing beyond any applicable period of grace or
(ii) any other default occurs and is continuing with respect to Designated
Senior Debt that permits holders of the Designated Senior Debt as to which such
default relates to accelerate its maturity and the Senior Subordinated Note
Trustee receives a notice of such default (a "Payment Blockage Notice"), for so
long as any Obligations are outstanding under the New Credit Facility, from the
Representative thereunder and, thereafter, from the holders or Representative of
any Designated Senior Debt. Payments on the Senior Subordinated Notes may and
shall be resumed (a) in the case of a payment default, upon the date on which
such default is cured or waived and (b) in the case of a nonpayment default, the
earlier of the date on which such nonpayment default is cured or waived or 179
days after the date on which the applicable Payment Blockage Notice is received,
unless the maturity of any Designated Senior Debt has been accelerated. No new
period of payment blockage may be commenced within 360 days after the receipt by
the Senior Subordinated Note Trustee of any prior Payment Blockage Notice. No
nonpayment default that
 
                                       79
<PAGE>
existed or was continuing on the date of delivery of any Payment Blockage Notice
to the Subordinated Note Trustee shall be, or be made, the basis for a
subsequent Payment Blockage Notice.
 
    The Senior Subordinated Note Indenture will further require that the Company
promptly notify holders of Senior Debt if payment of the Senior Subordinated
Notes is accelerated because of an Event of Default.
 
    As a result of the subordination provisions described above, in the event of
a liquidation or insolvency, Holders of Senior Subordinated Notes may recover
less ratably than creditors of the Company who are Holders of Senior Debt. On a
pro forma basis, as of November 30, 1996, after giving effect to the Merger and
the Refinancing, Senior Debt of the Company would have been approximately $
billion. The Senior Subordinated Note Indenture will limit, subject to certain
financial tests, the amount of additional Indebtedness, including Senior Debt,
that the Company and its Subsidiaries can incur. See "--Certain
Covenants--Incurrence of Indebtedness and Issuance of Preferred Stock."
 
    "DESIGNATED SENIOR DEBT" means (i) so long as any Obligations are
outstanding under the New Credit Facility, such Obligations and (ii) thereafter,
any other Senior Debt permitted under the Senior Subordinated Note Indenture the
principal amount of which is $100.0 million or more and that has been designated
by the Company as "Designated Senior Debt."
 
    "SENIOR DEBT" means (i) Indebtedness under the New Credit Facility, (ii) the
Senior Notes, the Existing Senior Notes, any other Indebtedness permitted to be
incurred by the Company under the terms of the Senior Subordinated Note
Indenture, unless the instrument under which such Indebtedness is incurred
expressly provides that it is on a parity with or subordinated in right of
payment to the Senior Subordinated Notes and (iii) all Obligations with respect
to any of the foregoing. Notwithstanding anything to the contrary in the
foregoing, Senior Debt will not include (v) the Senior Subordinated Notes, the
2005 Senior Subordinated Notes and the 2005 Exchangeable Subordinated Notes, (w)
any liability for Federal, state, local or other taxes owed or owing by the
Company, (x) any Indebtedness of the Company to any of its Subsidiaries or other
Affiliates, (y) any trade payables or (z) any Indebtedness that is incurred in
violation of the Senior Subordinated Note Indenture.
 
CERTAIN COVENANTS
 
  RESTRICTED PAYMENTS
 
    The Indentures will provide that the Company will not, and will not permit
any of its Subsidiaries to, directly or indirectly: (i) declare or pay any
dividend or make any distribution on account of the Company's or any of its
Subsidiaries' Equity Interests (other than (w) Physician Joint Venture
Distributions, (x) dividends or distributions payable in Qualified Equity
Interests of the Company, (y) dividends or distributions payable to the Company
or any Subsidiary of the Company, and (z) dividends or distributions by any
Subsidiary of the Company payable to all holders of a class of Equity Interests
of such Subsidiary on a PRO RATA basis); (ii) purchase, redeem or otherwise
acquire or retire for value any Equity Interests of the Company; or (iii) make
any principal payment on, or purchase, redeem, defease or otherwise acquire or
retire for value any Indebtedness that is subordinated to the Notes issued under
such Indenture, except at the original final maturity date thereof or pursuant
to a Specified Exchange or the Refinancing (all such payments and other actions
set forth in clauses (i) through (iii) above being collectively referred to as
"Restricted Payments"), unless, at the time of and after giving effect to such
Restricted Payment (the amount of any such Restricted Payment, if other than
cash, shall be the fair market value (as conclusively evidenced by a resolution
of the Board of Directors set forth in an Officers' Certificate delivered to the
Trustees within 60 days prior to the date of such Restricted Payment) of the
asset(s) proposed to be transferred by the Company or such Subsidiary, as the
case may be, pursuant to such Restricted Payment):
 
        (a) no Default or Event of Default shall have occurred and be continuing
    or would occur as a consequence thereof; and
 
        (b) the Company would, at the time of such Restricted Payment and after
    giving pro forma effect thereto as if such Restricted Payment had been made
    at the beginning of the most recently
 
                                       80
<PAGE>
    ended four full fiscal quarter period for which internal financial
    statements are available immediately preceding the date of such Restricted
    Payment, have been permitted to incur at least $1.00 of additional
    Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in
    the first paragraph of the covenant in the Indentures described below under
    the caption "--Incurrence of Indebtedness and Issuance of Preferred Stock";
    and
 
        (c) such Restricted Payment, together with the aggregate of all other
    Restricted Payments made by the Company and its Subsidiaries after March 1,
    1995 (excluding Restricted Payments permitted by clauses (v), (w) and (x) of
    the next succeeding paragraph), is less than the sum of (i) 50% of the
    Consolidated Net Income of the Company for the period (taken as one
    accounting period) from the beginning of the first fiscal quarter commencing
    after March 1, 1995 to the end of the Company's most recently ended fiscal
    quarter for which internal financial statements are available at the time of
    such Restricted Payment (or, if such Consolidated Net Income for such period
    is a deficit, less 100% of such deficit), PLUS (ii) 100% of the aggregate
    net cash proceeds received by the Company from the issue or sale (other than
    to a Subsidiary of the Company) since March 1, 1995 of Qualified Equity
    Interests of the Company or of debt securities of the Company or any of its
    Subsidiaries that have been converted into or exchanged for such Qualified
    Equity Interests of the Company, plus (iii) $20.0 million.
 
    If no Default or Event of Default has occurred and is continuing, or would
occur as a consequence thereof, the foregoing provisions will not prohibit the
following Restricted Payments: (u) the payment of any dividend within 60 days
after the date of declaration thereof, if at said date of declaration such
payment would have complied with the provisions of the Indentures; (v) the
payment of cash dividends on any series of Disqualified Stock issued after the
date of the Indentures in an aggregate amount not to exceed the cash received by
the Company since the date of the Indentures upon issuance of such Disqualified
Stock; (w) the redemption, repurchase, retirement or other acquisition of any
Equity Interests of the Company or any Subsidiary in exchange for, or out of the
net cash proceeds of, the substantially concurrent sale (other than to a
Subsidiary of the Company) of Qualified Equity Interests of the Company;
PROVIDED that the amount of any such net cash proceeds that are utilized for any
such redemption, repurchase, retirement or other acquisition shall be excluded
from clause (c)(ii) of the preceding paragraph; (x) the defeasance, redemption
or repurchase of subordinated Indebtedness with the net cash proceeds from an
incurrence of Permitted Refinancing Indebtedness or in exchange for or out of
the net cash proceeds from the substantially concurrent sale (other than to a
Subsidiary of the Company) of Qualified Equity Interests of the Company;
PROVIDED that the amount of any such net cash proceeds that are utilized for any
such redemption, repurchase, retirement or other acquisition shall be excluded
from clause (c)(ii) of the preceding paragraph; (y) the repurchase, redemption
or other acquisition or retirement for value of any Equity Interests of the
Company or any Subsidiary of the Company held by any member of the Company's (or
any of its Subsidiaries') management pursuant to any management equity
subscription agreement or stock option agreement; PROVIDED that the aggregate
price paid for all such repurchased, redeemed, acquired or retired Equity
Interests shall not exceed $15.0 million in any twelve-month period; and (z) the
making and consummation of (A) a senior subordinated asset sale offer in
accordance with the provisions of the indenture relating to the 2005 Senior
Subordinated Notes or (B) a Change of Control Offer with respect to the Senior
Subordinated Notes in accordance with the provisions of the Senior Subordinated
Note Indenture or a change of control offer with respect to the 2005 Senior
Subordinated Notes or the 2005 Exchangeable Subordinated Notes in accordance
with the provisions of the indentures relating thereto.
 
    Not later than the date of making any Restricted Payment, the Company shall
deliver to the Trustees an Officers' Certificate stating that such Restricted
Payment is permitted and setting forth the basis upon which the calculations
required by the covenant described under the caption "--Restricted Payments"
were computed.

  INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK
 
    The Indentures will provide that the Company will not, and will not permit
any of its Subsidiaries to, directly or indirectly, create, incur, issue,
assume, Guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, "incur") after the
date of the Indentures any Indebtedness (including Acquired Debt) and that the
Company will not issue any Disqualified Stock and will not permit any of its
Subsidiaries to issue any shares of preferred stock; PROVIDED, HOWEVER, that the
Company may incur Indebtedness (including Acquired Debt) and the Company may
issue shares of Disqualified Stock if the Fixed Charge Coverage Ratio for the
Company's most recently ended four full fiscal quarters for which internal
financial statements are available immediately preceding the date on which such
additional Indebtedness is incurred or such Disqualified Stock is issued would
have been at least 2.5 to 1, determined on a pro forma basis (including a pro
forma application of the net proceeds therefrom), as if the additional
Indebtedness had been incurred, or the Disqualified Stock had been issued, as
the case may be, at the beginning of such four-quarter period. Indebtedness
consisting of reimbursement obligations in respect of a letter of credit will be
deemed to be incurred when the letter of credit is first issued.
 
    The foregoing provisions will not apply to:
 
        (i) the incurrence by the Company of Indebtedness pursuant to the New
    Credit Facility in an aggregate principal amount at any time outstanding not
    to exceed an amount equal to $2.5 billion less the aggregate amount of all
    mandatory repayments applied to permanently reduce the commitments with
    respect to such Indebtedness;
 
        (ii) the incurrence by the Company of Indebtedness represented by the
    Notes;
 
       (iii) the incurrence by the Company and its Subsidiaries of the Existing
    Indebtedness;
 
        (iv) the incurrence by the Company or any of its Subsidiaries of
    Permitted Refinancing Indebtedness in exchange for, or the net proceeds of
    which are used to extend, refinance, renew, replace, defease or refund,
    Indebtedness that was permitted by the Indentures to be incurred (including,
    without limitation, Existing Indebtedness);
 
        (v) the incurrence by the Company or any of its Subsidiaries of
    intercompany Indebtedness between or among the Company and any of its
    Subsidiaries;
 
        (vi) the incurrence by the Company of Hedging Obligations that are
    incurred for the purpose of fixing or hedging interest rate or currency risk
    with respect to any fixed or floating rate Indebtedness that is permitted by
    the Indentures to be outstanding or any receivable or liability the payments
    of which is determined by reference to a foreign currency; PROVIDED that the
    notional principal amount of any such Hedging Obligation does not exceed the
    principal amount of the Indebtedness to which such Hedging Obligation
    relates;
 
       (vii) the incurrence by the Company or any of its Subsidiaries of
    Physician Support Obligations;
 
      (viii) the incurrence by the Company or any of its Subsidiaries of
    Indebtedness represented by tender, bid, performance, government contract,
    surety or appeal bonds, standby letters of credit or warranty or contractual
    service obligations of like nature, in each case to the extent incurred in
    the ordinary course of business of the Company or such Subsidiary;
 
        (ix) the incurrence by any Subsidiary of the Company of Indebtedness,
    the aggregate principal amount of which, together with all other
    Indebtedness of the Company's Subsidiaries at the time outstanding
    (excluding the Existing Indebtedness until repaid or refinanced and
    excluding Physician Support Obligations), does not exceed the greater of (1)
    10% of the Company's Stockholders' Equity as of the date of incurrence or
    (2) $10.0 million; PROVIDED that, in the case of clause (1) only, the Fixed
    Charge Coverage Ratio for the Company's most recently ended four full fiscal
    quarters for which internal financial statements are available immediately
    preceding the date on which such Indebtedness is incurred would have been at
    least 2.5 to 1, determined on a pro forma basis (including a pro
 
                                       82
<PAGE>
    forma application of the net proceeds therefrom), as if such Indebtedness
    had been incurred at the beginning of such four-quarter period; and
 
        (x) the incurrence by the Company of Indebtedness (in addition to
    Indebtedness permitted by any other clause of this paragraph) in an
    aggregate principal amount at any time outstanding not to exceed $250.0
    million.
 
  LIENS
 
    The Senior Note Indenture will provide that the Company will not, and will
not permit any of its subsidiaries to, directly or indirectly, create, incur,
assume or suffer to exist any Lien (except Permitted Liens) on any asset now
owned or hereafter acquired, or any income or profits therefrom or assign or
convey any right to receive income therefrom unless all payments due under the
Senior Note Indenture and the Senior Notes are secured on an equal and ratable
basis with the Obligations so secured until such time as such obligations are no
longer secured by a Lien.
 
    The Senior Subordinated Note Indenture will provide that the Company will
not, and will not permit any of its Subsidiaries to, directly or indirectly,
create, incur, assume or suffer to exist any Lien to secure Indebtedness that is
pari passu with or subordinated in right of payment to the Senior Subordinated
Notes (except Permitted Liens) on any asset now owned or hereafter acquired, or
any income or profits therefrom or assign or convey any right to receive income
therefrom unless all payments due under the Senior Subordinated Note Indenture
and the Senior Subordinated Notes are secured on an equal and ratable basis with
the Obligations so secured until such time as such Obligations are no longer
secured by a Lien.
 
  DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES
 
    The Indentures will provide that the Company will not, and will not permit
any of its Subsidiaries to, directly or indirectly, create or otherwise cause or
suffer to exist or become effective any consensual encumbrance or restriction on
the ability of any Subsidiary to (i)(a) pay dividends or make any other
distributions to the Company or any of its Subsidiaries (1) on its Capital Stock
or (2) with respect to any other interest or participation in, or measured by,
its profits, or (b) pay any Indebtedness owed to the Company or any of its
Subsidiaries, (ii) make loans or advances to the Company or any of its
Subsidiaries or (iii) transfer any of its properties or assets to the Company or

Indentures, (b) the Indentures, (c) applicable law, (d) any instrument governing
Indebtedness or Capital Stock of a Person acquired by the Company or any of its
Subsidiaries as in effect at the time of such acquisition (except to the extent
such Indebtedness was incurred in connection with or in contemplation of such
acquisition, unless such Indebtedness was incurred in connection with or in
contemplation of such acquisition for the purpose of refinancing Indebtedness
which was tax-exempt, or in violation of the covenant described above under the
caption "--Incurrence of Indebtedness and Issuance of Preferred Stock"), which
encumbrance or restriction is not applicable to any Person, or the properties or
assets of any Person, other than the Person, or the property or assets of the
Person, so acquired, provided that the Consolidated Cash Flow of such Person is
not taken into account in determining whether such acquisition was permitted by
the terms of the Indentures except to the extent that such Consolidated Cash
Flow would be permitted to be dividends to the Company without the prior consent
or approval of any third party, (e) customary non-assignment provisions in
leases entered into in the ordinary course of business, (f) purchase money
obligations for property acquired in the ordinary course of business that impose
restrictions of the nature described in clause (iii) above on the property so
acquired, (g) Permitted Refinancing Indebtedness, provided that the restrictions
contained in the agreements governing such Permitted Refinancing Indebtedness
are no more restrictive than those contained in the agreements governing the
Indebtedness being refinanced, or (h) the New Credit Facility and related
documentation as the same is in effect on the date of the Indentures and as
amended or replaced from time to time, provided that no such amendment or
replacement is more restrictive as to the matters enumerated above than the New
Credit Facility and related documentation as in effect on the date of the
Indentures.

Net Worth immediately after the transaction equal to or greater than the
Consolidated Net Worth of the Company immediately preceding the transaction and
(B) will, at the time of such transaction and after giving pro forma effect
thereto as if such transaction had occurred at the beginning of the applicable
four-quarter period, be permitted to incur at least $1.00 of additional
Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the
first paragraph of the covenant in the applicable Indenture described above
under the caption "--Incurrence of Indebtedness and Issuance of Preferred

  TRANSACTIONS WITH AFFILIATES
 
    The Indentures will provide that the Company will not, and will not permit
any of its Subsidiaries to, sell, lease, transfer or otherwise dispose of any of
its properties or assets to, or purchase any property or assets from, or enter
into or make any contract, agreement, understanding, loan, advance or Guarantee
with, or for the benefit of, any Affiliate (each of the foregoing, an "Affiliate
Transaction"), unless (i) such Affiliate Transaction is on terms that are no
less favorable to the Company or the relevant Subsidiary than those that could
have been obtained in a comparable transaction by the Company or such Subsidiary
with an unrelated Person and (ii) the Company delivers to the applicable Trustee
(a) with respect to any Affiliate Transaction involving aggregate consideration
in excess of $5.0 million, a resolution of the Board of Directors set forth in
an Officers' Certificate certifying that such Affiliate Transaction complies
with clause (i) above and that such Affiliate Transaction has been approved by a
majority of the disinterested members of the Board of Directors and (b) with
respect to any Affiliate Transaction involving aggregate consideration in excess

  LIMITATIONS ON ISSUANCES OF GUARANTEES OF INDEBTEDNESS BY SUBSIDIARIES
 
    The Senior Note Indenture will provide that the Company will not permit any
Subsidiary, directly or indirectly, to Guarantee or secure the payment of any
other Indebtedness of the Company or any of its Subsidiaries (except
Indebtedness of a Subsidiary of such Subsidiary or Physician Support
Obligations) unless such Subsidiary simultaneously executes and delivers a
supplemental indenture to the Senior Note Indenture providing for the Guarantee
of the payment of the Senior Notes by such Subsidiary, which Guarantee shall be
senior to or PARI PASSU with such Subsidiary's Guarantee of or pledge to secure
such other Indebtedness. The Senior Subordinated Note Indenture will provide
that the Company will not permit any Subsidiary, directly or indirectly, to
Guarantee or secure the payment of any other Indebtedness of the Company or any
of its Subsidiaries (except Indebtedness of a Subsidiary of such Subsidiary or
Physician Support Obligations) unless such Subsidiary simultaneously executes
and delivers a supplemental indenture to the Senior Subordinated Note Indenture
providing for the Guarantee of the payment of the Senior Subordinated Notes by
such Subsidiary, which Guarantee shall be subordinated to such Subsidiary's
Guarantee of or pledge to secure such other Indebtedness to the same extent as
the Senior Subordinated Notes are subordinated to such other Indebtedness under
the Senior Subordinated Note Indenture. Notwithstanding the foregoing, any such
Guarantee by a Subsidiary of the Notes shall provide by its terms that it shall
be automatically and unconditionally released and discharged upon the sale or
other disposition, by way of merger or otherwise, to any Person not an Affiliate
of the Company, of all of the Company's stock in, or all or substantially all
the assets of, such Subsidiary. The forms of such supplemental indentures will
be attached as exhibits to the Indentures. The foregoing provisions will not be
applicable to any one or more Guarantees that otherwise would be prohibited of
up to $10.0 million in aggregate principal amount of Indebtedness of the Company
or its Subsidiaries at any time outstanding.
 
  NO AMENDMENT TO SUBORDINATION PROVISIONS
 
    The Senior Note Indenture will provide that the Company will not amend,
modify or alter the Senior Subordinated Note Indenture or the indentures
relating to the 2005 Senior Subordinated Notes or the 2005 Exchangeable
Subordinated Notes in any way that would (i) increase the principal of, advance
the final maturity date of or shorten the Weighted Average Life to Maturity of
(a) any 2005 Senior Subordinated Notes or 2005 Exchangeable Subordinated Notes
or (b) any Senior Subordinated Notes such that the final maturity date of the
Senior Subordinated Notes is earlier than the 91st day following the final
maturity date of the Senior Notes or (ii) amend the provisions of Article 10 of
the Senior Subordinated Note Indenture (which relates to subordination) or the
subordination provisions of the indentures relating to the 2005 Senior
Subordinated Notes or the 2005 Exchangeable Subordinated Notes or any of the
defined terms used therein in a manner that would be adverse to the Holders of
the Senior Notes.
 
  NO SENIOR SUBORDINATED DEBT
 
    The Senior Subordinated Note Indenture will provide that the Company will
not incur any Indebtedness that is subordinate or junior in right of payment to
any Senior Debt and senior in any respect in right of payment to the Senior
Subordinated Notes.
 
  REPORTS
 
    The Indentures will provide that, whether or not required by the rules and
regulations of the Commission, so long as any Notes are outstanding, the Company
will furnish to the Holders of Notes (i) all quarterly and annual financial
information that would be required to be contained in a filing with the
Commission on Forms 10-Q and 10-K if the Company were required to file such
Forms, including a "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and, with respect to the annual information only, a
report thereon by the Company's certified independent accountants and (ii) all
current reports that would be required to be filed with the Commission on Form
8-K if the Company were required to file such reports. In addition, whether or
not required by the rules and regulations of the Commission, the Company will
file a copy of all such information and reports
 
                                       85
<PAGE>
with the Commission for public availability and make such information available
to securities analysts and prospective investors upon request.
 
EVENTS OF DEFAULT AND REMEDIES
 
    The Indentures will provide that each of the following constitutes an Event
of Default: (i) default for 30 days in the payment when due of interest on the
respective series of Notes (whether or not prohibited by the subordination
provisions of the Senior Subordinated Note Indenture); (ii) default in payment
when due of the principal of or premium, if any, on the respective series of
Notes (whether or not prohibited by the subordination provisions of the Senior
Subordinated Note Indenture); (iii) failure by the Company to comply with the
provisions described under the captions "--Repurchase at the Option of Holders
Upon a Change of Control," "--Certain Covenants--Restricted Payments" or
"--Incurrence of Indebtedness and Issuance of Preferred Stock"; (iv) failure by
the Company for 60 days after notice to comply with any of its other agreements
in the Indentures or the Notes; (v) in the case of the Senior Notes Indenture
only, any default occurs under any mortgage, indenture or instrument under which
there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Company or any of its Significant
Subsidiaries (or the payment of which is Guaranteed by the Company or any of its
Significant Subsidiaries), whether such Indebtedness or Guarantee exists on the
date of the Indentures or is thereafter created, which default (a) constitutes a
Payment Default or (b) results in the acceleration of such Indebtedness prior to
its express maturity and, in each case, the principal amount of any
Indebtedness, together with the principal amount of any other such Indebtedness
under which there has been a Payment Default or that has been so accelerated,
aggregates $25.0 million or more; (vi) in the case of the Senior Subordinated
Note Indenture only, any default occurs under any mortgage, indenture or
instrument under which there may be issued or by which there may be secured or
evidenced any Indebtedness for money borrowed by the Company or any of its
Significant Subsidiaries (or the payment of which is guaranteed by the Company
or any of its Significant Subsidiaries), whether such Indebtedness or Guarantee
exists on the date of the Senior Subordinated Note Indenture or is thereafter
created, which default (a) constitutes a failure to pay principal at final
maturity or (b) results in the acceleration of such Indebtedness prior to its
express maturity and, in each case, the principal amount of such Indebtedness,
together with the principal amount of any other such Indebtedness that has not
been paid at final maturity or that has been so accelerated, aggregates $25.0
million or more; (vii) failure by the Company or any of its Significant
Subsidiaries to pay final judgments aggregating in excess of $25.0 million,
which judgments are not paid, discharged or stayed for a period of 60 days; and
(viii) certain events of bankruptcy or insolvency with respect to the Company or
any of its Significant Subsidiaries.
 
    If any Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in principal amount of the then outstanding Senior Notes or
Senior Subordinated Notes, as the case may be, may declare all the Senior Notes
or Senior Subordinated Notes, as the case may be, to be due and payable
immediately. Notwithstanding the foregoing, in the case of an Event of Default
arising from certain events of bankruptcy or insolvency with respect to the
Company or any of its Significant Subsidiaries, all outstanding Notes will
become due and payable without further action or notice. Holders of the Notes
may not enforce the Indentures or the Notes except as provided in the
Indentures. Subject to certain limitations, Holders of a majority in principal
amount of the then outstanding Notes may direct the applicable Trustee in its
exercise of any trust or power. Either Trustee may withhold from Holders of the
Notes notice of any continuing Default or Event of Default (except a Default or
Event of Default relating to the payment of principal or interest) if it
determines that withholding notice is in their interest.
 
    In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have had
to pay if the Company then had elected to redeem the Senior Subordinated Notes
pursuant to the optional redemption provisions of the Senior Subordinated Note
Indenture, an equivalent premium shall also become and be immediately due and
payable to the extent permitted by law upon the acceleration of the Senior
Subordinated Notes. If an Event of Default occurs under the Senior Note
Indenture prior to maturity or under the Senior Subordinated Note Indenture
prior to January 15,
 
                                       86
<PAGE>
2002 by reason of any willful action (or inaction) taken (or not taken) by or on
behalf of the Company with the intention of avoiding the prohibition on
redemption of such Notes prior to such dates, then the premium specified in the
applicable Indenture shall also become immediately due and payable to the extent
permitted by law upon the acceleration of such Notes.
 
    The Holders of a majority in aggregate principal amount of the Senior Notes
or Senior Subordinated Notes, as the case may be, then outstanding by notice to
the applicable Trustee on behalf of the Holders of all of the Senior Notes or
Senior Subordinated Notes, as the case may be, may waive any existing Default or
Event of Default and its consequences under the applicable Indenture except a
continuing Default or Event of Default in the payment of interest on, or the
principal of, the Senior Notes or Senior Subordinated Notes, as the case may be.
 
    The Company is required to deliver to each Trustee annually a statement
regarding compliance with the respective Indentures, and the Company is required
upon becoming aware of any Default or Event of Default, to deliver to the
Trustees a statement specifying such Default or Event of Default.
 
NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDER
 
    No director, officer, employee, incorporator or stockholder of the Company,
as such, shall have any liability for any obligations of the Company under the
Notes, the Indentures or for any claim based on, in respect of, or by reason of,
such obligations or their creation. Each Holder of Notes by accepting a Note
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes. Such waiver may not be effective to
waive liabilities under the Federal securities laws and it is the view of the
Commission that such a waiver is against public policy.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
    The Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding Senior Notes or Senior
Subordinated Notes ("Legal Defeasance") except for (i) the rights of Holders of
outstanding Notes to receive payments in respect of the principal of, premium,
if any, and interest on such Notes when such payments are due from the trust
referred to below, (ii) the Company's obligations with respect to the Notes
concerning issuing temporary Notes, registration of Notes, mutilated, destroyed,
lost or stolen Notes and the maintenance of an office or agency for payment and
money for security payments held in trust, (iii) the rights, powers, trusts,
duties and immunities of the applicable Trustee, and the Company's obligations
in connection therewith and (iv) the Legal Defeasance provisions of the
applicable Indenture. In addition, the Company may, at its option and at any
time, elect to have the obligations of the Company released with respect to
certain covenants that are described in the Senior Note Indenture or the Senior
Subordinated Note Indenture ("Covenant Defeasance") and thereafter any omission
to comply with such obligations shall not constitute a Default or Event of
Default with respect to the Senior Notes or the Senior Subordinated Notes, as
the case may be. In the event Covenant Defeasance occurs, certain events (not
including non-payment, bankruptcy, receivership, rehabilitation and insolvency
events) described under "--Events of Default and Remedies" will no longer
constitute an Event of Default with respect to the Senior Notes or the Senior
Subordinated Notes, as the case may be.
 
    In order to exercise either Legal Defeasance or Covenant Defeasance, (i) the
Company must irrevocably deposit with the appropriate Trustee, in trust, for the
benefit of the Holders of the Senior Notes or the Senior Subordinated Notes, as
the case may be, cash in U.S. dollars, non-callable Government Securities, or a
combination thereof, in such amounts as will be sufficient, in the opinion of a
nationally recognized firm of independent public accountants, to pay the
principal of, premium, if any, and interest on such outstanding Notes on the
stated maturity or on the applicable redemption date, as the case may be, and,
in the case of the Senior Subordinated Notes, the Company must specify whether
the Senior Subordinated Notes are being defeased to maturity or to a particular
redemption date (in which case the Company shall issue an irrevocable notice of
redemption as of a specified date that will be delivered by the applicable
Trustee in accordance with the redemption provisions of the Senior Subordinated
Note Indenture); (ii) in the case of Legal Defeasance, the Company shall have
delivered to the appropriate
 
                                       87
<PAGE>
Trustee an opinion of counsel in the United States confirming that (A) the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling or (B) since the date of the applicable Indenture, there has
been a change in the applicable Federal income tax law, in either case to the
effect that, and based thereon such opinion of counsel shall confirm that, the
Holders of such outstanding Notes will not recognize income, gain or loss for
Federal income tax purposes as a result of such Legal Defeasance and will be
subject to Federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such Legal Defeasance had not
occurred; (iii) in the case of Covenant Defeasance before the date that is one
year prior to the final maturity of the Notes, the Company shall have delivered
to the appropriate Trustee an opinion of counsel in the United States confirming
that the Holders of such outstanding Notes will not recognize income, gain or
loss for Federal income tax purposes as a result of such Covenant Defeasance and
will be subject to Federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such Covenant Defeasance
had not occurred; (iv) no Default or Event of Default shall have occurred and be
continuing on the date of such deposit (other than a Default or Event of Default
resulting from the borrowing of funds to be applied to such deposit) or insofar
as Events of Default from bankruptcy or insolvency events are concerned, at any
time in the period ending on the 91st day after the date of deposit; (v) such
Legal Defeasance or Covenant Defeasance will not result in a breach or violation
of, or constitute a default under any material agreement or instrument (other
than the applicable Indenture) to which the Company or any of its Subsidiaries
is a party or by which the Company or any of its Subsidiaries is bound (other
than a breach, violation or default resulting from the borrowing of funds to be
applied to such deposit); (vi) the Company must have delivered to the
appropriate Trustee an opinion of counsel to the effect that after the 91st day
following the deposit, the trust funds will not be subject to the effect of any
applicable bankruptcy, insolvency, reorganization or similar laws affecting
creditors' rights generally; (vii) the Company must deliver to the appropriate
Trustee an Officers' Certificate stating that the deposit was not made by the
Company with the intent of preferring the Holders of such Notes over the other
creditors of the Company with the intent of defeating, hindering, delaying or
defrauding creditors of the Company or others; and (viii) the Company must
deliver to the appropriate Trustee an Officers' Certificate stating that all
conditions precedent provided for relating to the Legal Defeasance or the
Covenant Defeasance have been complied with.
 
TRANSFER AND EXCHANGE
 
    A Holder may transfer or exchange Notes in accordance with the Indentures.
The Registrar and the Trustees may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and the Company may
require a Holder to pay any taxes and fees required by law or permitted by the
Indentures. The Company is not required to transfer or exchange any Senior
Subordinated Note selected for redemption. Also, the Company is not required to
transfer or exchange any Senior Subordinated Note for a period of 15 days before
a selection of Senior Subordinated Notes to be redeemed.
 
    The registered Holder of a Note will be treated as the owner of it for all
purposes. See "--Global Notes."
 
GLOBAL NOTES
 
    The Notes will each be issued in the form of one or more registered Notes in
book-entry form (each, a "Global Note") that will be deposited with, or on
behalf of, The Depositary Trust Company ("DTC") and registered in the name of
DTC's nominee. Except as set forth below, a Global Note may not be transferred
except as a whole by DTC to a nominee of DTC or any such nominee to a successor
of DTC or a nominee of such successor.
 
    So long as DTC or its nominee is the registered Holder of a Global Note, DTC
or its nominee, as the case may be, will be treated as the sole owner of it for
all purposes under the Indenture and the beneficial owners of Notes will be
entitled only to those rights and benefits afforded to them in accordance with
DTC's regular operating procedures. Upon specified written instructions of a
Participant (defined below), DTC will have its nominee assist Participants in
the exercise of certain Holders' rights, such as a demand
 
                                       88
<PAGE>
for acceleration or an instruction to the Trustee. Except as provided below,
owners of beneficial interests in a Global Note will not be entitled to have
Notes represented by a Global Note registered in their names, will not receive
or be entitled to receive physical delivery of Notes in certificated form and
will not be considered the registered Holders thereof under the Indenture.
 
    If (i) DTC is at any time unwilling or unable to continue as depository or
if at any time DTC ceases to be a clearing agency registered under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and a
successor depository is not appointed by the Company within 90 days, (ii) an
Event of Default under the applicable Indenture with respect to the notes has
occurred and is continuing and the beneficial owners representing a majority in
principal amount of the Notes advise DTC to cease acting as depository or (iii)
the Company, in its sole discretion, determines at any time that the Notes shall
no longer be represented by a Global Note, the Company will issue individual
Notes of the applicable amount and in certificated form in exchange for a Global
Note. In any such instance, an owner of a beneficial interest in the Global Note
will be entitled to physical delivery of individual notes in certificated form
of like tenor, equal in principal amount to such beneficial interest and to have
such Notes in certificated form registered in its name.
 
    DTC has advised the Company that it is a limited-purpose trust company
organized under the New York Banking Law, a "banking organization" within the
meaning of the New York Banking Law, a member of the Federal Reserve System, a
"clearing corporation" within the meaning of the New York Uniform Commercial
Code and a "clearing agency" registered pursuant to the provisions of Section
17A of the Exchange Act. DTC holds certificates that its participants
("Participants") deposit with DTC. DTC also facilitates the settlement among
Participants of securities transactions, such as transfers and pledges, in
deposited securities through electronic computerized book-entry changes in
Participants' accounts, thereby eliminating the need for the physical movement
of securities certificates. Direct Participants include securities brokers and
dealers, banks, trust companies, clearing corporations and certain other
organizations ("Direct Participants"). DTC is owned by a number of its Direct
Participants and by the New York Stock Exchange, Inc., the American Stock
Exchange, Inc. and the National Association of Securities Dealers, Inc. Access
to the DTC system is also available to others such as securities brokers and
dealers, banks and trust companies that clear through or maintain a custodial
relationship with a Direct Participant, either directly or indirectly ("Indirect
Participants"). The rules applicable to DTC and its Participants are on file
with the Commission.
 
    None of the Company, the Trustee or the Underwriters will have any
responsibility for any aspect of the records relating to or payments made on
account of beneficial interests in a Global Note, or for maintaining,
supervising or reviewing any records relating to such beneficial interests.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
    Except as provided in the next two succeeding paragraphs, the Indentures or
the Notes may be amended or supplemented with the consent of the Holders of at
least a majority in principal amount of the Senior Notes or Senior Subordinated
Notes, as the case may be, then outstanding (including consents obtained in
connection with a tender offer or exchange offer for such Notes), and any
existing default or compliance with any provision of the Indentures or the Notes
may be waived with the consent of the Holders of a majority in principal amount
of the then outstanding Senior Notes or Senior Subordinated Notes, as the case
may be (including consents obtained in connection with a tender offer or
exchange offer for such Notes).
 
    Without the consent of each Holder affected, an amendment or waiver may not
(with respect to any Notes held by a non-consenting Holder): (i) reduce the
principal amount of Notes whose Holders must consent to an amendment, supplement
or waiver, (ii) reduce the principal of or change the fixed maturity of any Note
or, in the case of the Senior Subordinated Note Indenture, alter the provisions
with respect to the redemption of the Senior Subordinated Notes (other than
provisions relating to the covenants described above under the caption
"--Repurchase at the Option of Holders Upon a Change of Control"), (iii) reduce
the rate of or change the time for payment of interest on any Note, (iv) waive a
Default or
 
                                       89
<PAGE>
Event of Default in the payment of principal of or premium, if any, or interest
on the Notes (except a rescission of acceleration of the Senior Notes or Senior
Subordinated Notes, as the case may be, by the Holders of at least a majority in
aggregate principal amount and a waiver of the payment default that resulted
from such acceleration), (v) make any Note payable in money other than that
stated in the Notes, (vi) make any change in the provisions of the Indentures
relating to waivers of past Defaults or the rights of Holders of Notes to
receive payments of principal of or premium, if any, or interest on the Notes,
(vii) in the case of the Senior Subordinated Note Indenture, waive a redemption
payment with respect to any Senior Subordinated Note (other than a payment
required by one of the covenants described above under the caption "--Repurchase
at the Option of Holders Upon a Change of Control") or (viii) make any change in
the foregoing amendment and waiver provisions. In addition, any amendment to the
provisions of Article 10 of the Senior Subordinated Note Indenture (which relate
to subordination) will require the consent of the Holders of at least 75% in
aggregate principal amount of the Senior Subordinated Notes then outstanding if
such amendment would adversely affect the rights of Holders of Senior
Subordinated Notes.
 
    Notwithstanding the foregoing, without the consent of any Holder of Notes,
the Company and the appropriate Trustee may amend or supplement the Indentures
or the Notes to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for any supplemental indenture described above under the caption
"--Certain Covenants-- Limitation on Issuances of Guarantees of Indebtedness by
Subsidiaries," to provide for the assumption of the Company's obligations to
Holders of Notes in the case of a merger or consolidation, to make any change
that would provide any additional rights or benefits to the Holders of Notes or
that does not adversely affect the legal rights under the Indentures of any such
Holder, or to comply with requirements of the Commission in order to effect or
maintain the qualification of the Indentures under the Trust Indenture Act.
 
CONCERNING THE TRUSTEE
 
    The Indentures will contain certain limitations on the rights of the
Trustees, should either Trustee become a creditor of the Company, to obtain
payment of claims in certain cases, or to realize on certain property received
in respect of any such claim as security or otherwise. The Trustees will be
permitted to engage in other transactions; however, if either Trustee acquires
any conflicting interest it must eliminate such conflict within 90 days, apply
to the Commission for permission to continue or resign.
 
    The Holders of a majority in principal amount of the then outstanding Senior
Notes or Senior Subordinated Notes, as the case may be, will have the right to
direct the time, method and place of conducting any proceeding for exercising
any remedy available to the applicable Trustee, subject to certain exceptions.
The Indentures provide that in case an Event of Default shall occur (which shall
not be cured), the Trustees will be required, in the exercise of their power, to
use the degree of care of a prudent man in the conduct of his own affairs.
Subject to such provisions, neither Trustee will be under any obligation to
exercise any of its rights or powers under the Indentures at the request of any
Holder of Notes, unless such Holder shall have offered to the appropriate
Trustee security and indemnity satisfactory to it against any loss, liability or
expense.
 
CERTAIN DEFINITIONS
 
    Set forth below are certain defined terms used in the Indentures. Reference
is made to the Indentures for a full disclosure of all such terms, as well as
any other capitalized terms used herein for which no definition is provided.
 
    "ACQUIRED DEBT"  means, with respect to any specified Person, (i)
Indebtedness of any other Person existing at the time such other Person is
merged with or into or became a Subsidiary of such specified Person, including,
without limitation, Indebtedness incurred in connection with, or in
contemplation of, such other Person merging with or into or becoming a
Subsidiary of such specified Person, and (ii) Indebtedness secured by a Lien
encumbering any asset acquired by such specified Person.
 
                                       90
<PAGE>
    "AFFILIATE"  of any specified Person means any other Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with such specified Person. For purposes of this definition, "control"
(including, with correlative meanings, the terms "controlling," "controlled by"
and "under common control with"), as used with respect to any Person, shall mean
the possession, directly or indirectly, of the power to direct or cause the
direction of the management or policies of such Person, whether through the
ownership of voting securities, by agreement or otherwise; provided that
beneficial ownership of 10% or more of the voting securities of a Person shall
be deemed to be control.
 
    "ASSET SALE"  means (i) the sale, lease, conveyance or other disposition of
any assets (including, without limitation, by way of a sale and leaseback) other
than in the ordinary course of business consistent with past practices and (ii)
the issuance or sale by the Company or any of its Subsidiaries of Equity
Interests of any of the Company's Subsidiaries, in the case of either clause (i)
or (ii), whether in a single transaction or a series of related transactions (a)
that have a fair market value in excess of $25.0 million or (b) for net proceeds
in excess of $25.0 million. Notwithstanding the foregoing: (a) a transfer of
assets by the Company to a Subsidiary or by a Subsidiary to the Company or to
another Subsidiary, (b) an issuance of Equity Interests by a Subsidiary to the
Company or to another Subsidiary, (c) a Restricted Payment that is permitted by
the covenant described above under the caption "--Certain Covenants--Restricted
Payments" and (d) a Hospital Swap will not be deemed to be an Asset Sale.
 
    "CAPITAL LEASE OBLIGATION"  means, at the time any determination thereof is
to be made, the amount of the liability in respect of a capital lease that would
at such time be required to be capitalized on a balance sheet in accordance with
GAAP.
 
    "CAPITAL STOCK"  means (i) in the case of a corporation, corporate stock,
(ii) in the case of an association or business entity, any and all shares,
interests, participations, rights or other equivalents (however designated) of
corporate stock, (iii) in the case of a partnership, partnership interests
(whether general or limited) and (iv) any other interest or participation that
confers on a Person the right to receive a share of the profits and losses of,
or distributions of assets of, the issuing Person.
 
    "CHANGE OF CONTROL"  means the occurrence of any of the following: (i) the
sale, lease, transfer, conveyance or other disposition, in one or a series of
related transactions, of all or substantially all of the assets of the Company
and its Subsidiaries taken as a whole to any Person or group (as such term is
used in Sections 13(d)(3) and 14(d)(2) of the Exchange Act) other than to a
Person or group who, prior to such transaction, held a majority of the voting
power of the voting stock of the Company, (ii) the acquisition by any Person or
group (as defined above) of a direct or indirect interest in more than 50% of
the voting power of the voting stock of the Company, by way of merger or
consolidation or otherwise, or (iii) the first day on which a majority of the
members of the Board of Directors of the Company are not Continuing Directors.
 
    The phrase "all or substantially all" of the assets of the Company will
likely be interpreted under applicable state law and will be dependent upon
particular facts and circumstances. As a result, there may be a degree of
uncertainty in ascertaining whether a sale or transfer of "all or substantially
all" of the assets of the Company has occurred, in which case a holder's ability
to obtain the benefit of a Change of Control Offer may be impaired. In addition,
no assurances can be given that the Company will be able to acquire Notes
tendered upon the occurrence of a Change of Control Triggering Event.
 
    "CHANGE OF CONTROL TRIGGERING EVENT"  means the occurrence of both a Change
of Control and a Rating Decline.
 
    "CONSOLIDATED CASH FLOW"  means, with respect to any Person for any period,
the Consolidated Net Income of such Person for such period PLUS (i) an amount
equal to any extraordinary loss plus any net loss realized in connection with an
Asset Sale (to the extent such losses were deducted in computing such
Consolidated Net Income), PLUS (ii) provision for taxes based on income or
profits of such Person and its Subsidiaries for such period, to the extent that
such provision for taxes was included in computing such Consolidated Net Income,
PLUS (iii) the Fixed Charges of such Person and its Subsidiaries for such
period,
 
                                       91
<PAGE>
to the extent that such Fixed Charges were deducted in computing such
Consolidated Net Income, PLUS (iv) depreciation and amortization (including
amortization of goodwill and other intangibles but excluding amortization of
prepaid cash expenses that were paid in a prior period) of such Person and its
Subsidiaries for such period to the extent that such depreciation and
amortization were deducted in computing such Consolidated Net Income, in each
case, on a consolidated basis and determined in accordance with GAAP.
 
    Notwithstanding the foregoing, the provision for taxes on the income or
profits of, and the depreciation and amortization of, a Subsidiary of the
referent Person shall be added to Consolidated Net Income to compute
Consolidated Cash Flow only to the extent (and in same proportion) that the Net
Income of such Subsidiary was included in calculating the Consolidated Net
Income of such Person and only if a corresponding amount would be permitted at
the date of determination to be dividended to the Company by such Subsidiary
without prior approval (that has not been obtained), pursuant to the terms of
its charter and all agreements, instruments, judgments, decrees, orders,
statutes, rules and governmental regulations applicable to that Subsidiary or
its stockholders.
 
    "CONSOLIDATED NET INCOME"  means, with respect to any Person for any period,
the aggregate of the Net Income of such Person and its Subsidiaries for such

Underwriters are subject to certain conditions precedent, including the
consummation of the Merger and the OrNda Tender Offers. The Company has agreed
to indemnify the Underwriters against certain liabilities and expenses,
including liabilities under the Securities Act or to contribute to payments that

Notes directly to the public initially at the public offering price set forth on

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors
Tenet Healthcare Corporation:
 
    We have audited the accompanying consolidated balance sheets of Tenet
Healthcare Corporation and subsidiaries as of May 31, 1996 and 1995, and the
related consolidated statements of operations, shareholders' equity and cash
flows for each of the years in the three-year period ended May 31, 1996. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Tenet
Healthcare Corporation and subsidiaries as of May 31, 1996 and 1995, and the
results of their operations and their cash flows for each of the years in the
three-year period ended May 31, 1996, in conformity with generally accepted
accounting principles.
 
    As discussed in Note 6 to the consolidated financial statements, the Company
changed its method of accounting for income taxes effective June 1, 1993.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1. SIGNIFICANT ACCOUNTING POLICIES
 
A.  THE COMPANY
 
    Tenet Healthcare Corporation is an investor-owned healthcare services
company that owns or operates, through its subsidiaries and affiliates, general
hospitals and related healthcare facilities serving urban and rural communities
in 13 states and holds investments in other healthcare companies. At May 31,
1996, the Company's subsidiaries operated 74 domestic general hospitals, with a
total of 16,666 licensed beds, located in Alabama, Arkansas, California,
Florida, Georgia, Indiana, Louisiana, Missouri, Nebraska, North Carolina, South
Carolina, Tennessee and Texas. The largest concentrations of hospitals are in
California, Florida, Louisiana and Texas. At May 31, 1996, the Company's
subsidiaries also owned or operated a small number of rehabilitation hospitals,
long-term-care facilities and psychiatric facilities located on the same campus
as, or nearby, the Company's general hospitals, in addition to numerous other
ancillary healthcare operations.
 
B.  PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements include the accounts of Tenet
Healthcare Corporation and its wholly-owned and majority-owned subsidiaries.
Significant investments in other affiliated companies generally are accounted
for by the equity method. Intercompany accounts and transactions are eliminated
in consolidation.
 
C.  USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management of the Company to make
estimates and assumptions that affect the amounts reported in the consolidated
financial statements and accompanying notes. Actual results could differ from
those estimates.
 
D.  NET OPERATING REVENUES
 
    Net operating revenues consist primarily of net patient-service revenues,
which are based on the hospitals' established billing rates less allowances and
discounts principally for patients covered by Medicare, Medicaid and other
contractual programs. These allowances and discounts were $2.7 billion, $3.4
billion and $6.2 billion for the years ended May 31, 1994, 1995 and 1996,
respectively. Payments under these programs are based on either predetermined
rates or the costs of services. Settlements for retrospectively determined rates
are estimated in the period the related services are rendered and are adjusted
in future periods as final settlements are determined. Management believes that
adequate provision has been made for adjustments that may result from final
determination of amounts earned under these programs. These contractual
allowances and discounts are deducted from accounts receivable in the
accompanying consolidated balance sheets. Approximately 43% of fiscal 1996
consolidated net operating revenues is from participation of the Company's
hospitals in Medicare and Medicaid programs. In 1994 and 1995 it was
approximately 40%.
 
    The Company provides care to patients who meet certain financial or economic
criteria without charge or at amounts substantially less than its established
rates. Because the Company does not pursue collection of amounts determined to
qualify as charity care, they are not reported as gross revenue and are not
included in deductions from revenue or in operating and administrative expenses.
 
E.  CASH EQUIVALENTS
 
    The Company treats highly liquid investments with an original maturity of
three months or less as cash equivalents.

NOTE 1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
F.  INVESTMENTS IN DEBT AND EQUITY SECURITIES
 
    Investments in debt and equity securities are classified as
available-for-sale, held-to-maturity or as part of a trading portfolio. The
Company has no significant investments in securities classified as either
held-to-maturity or trading. Securities classified as available-for-sale are
carried at fair value if unrestricted and their unrealized gains and losses, net
of tax, are reported as an adjustment to shareholders' equity. Restricted
securities are carried at cost, adjusted for dividends in excess of earnings
subsequent to the date of investment and for decreases in value that are other
than temporary. Realized gains or losses are included in net income on the
specific identification method, and are immaterial for all years presented.
 
G.  LONG-LIVED ASSETS
 
  PROPERTY, PLANT AND EQUIPMENT
 
    The Company uses the straight-line method of depreciation for buildings,
building improvements and equipment over their estimated useful lives as
follows: buildings and improvements--generally 25 to 40 years; equipment--five
to 15 years.
 
  INTANGIBLE ASSETS
 
    Preopening costs are amortized over one year. Costs in excess of the fair
value of the net assets of purchased businesses (goodwill) generally are
amortized over 40 years. The straight-line method is used to amortize these
intangible assets. Deferred financing costs are amortized over the lives of the
related loans using the interest method.
 
    Impairment of long-lived assets, including goodwill related to such assets,
is recognized whenever events or changes in circumstances indicate that the
carrying amount of the asset, or related groups of assets, may not be
recoverable. Measurement of the amount of impairment may be based on appraisal,
market values of similar assets or estimates of future discounted cash flows
resulting from use and ultimate disposition of the asset.
 
H. LEASES
 
    Capital leases are recorded at the beginning of the lease term as assets and
liabilities at the lower of the present value of the minimum lease payments or
the fair value of the assets, and such assets are amortized over the shorter of
the lease term or their useful life.
 
I.  INTEREST RATE SWAP AGREEMENTS
 
    The differentials to be paid or received under interest rate swap agreements
are accrued as the interest rates change and are recognized over the lives of
the agreements as adjustments to interest expense.
 
J.  SALES OF COMMON STOCK OF SUBSIDIARIES
 
    At the time a subsidiary or equity affiliate sells existing or newly issued
common stock to unrelated parties at a price in excess of its book value, the
Company records a gain reflecting its share of the change in the subsidiary's
shareholders' equity resulting from the sale.
 
K. EARNINGS PER SHARE
 
    Primary earnings per share of common stock is based on after-tax income
applicable to common stock and the weighted average number of shares of common
stock and common stock equivalents outstanding

during each period as appropriate. Fully diluted earnings-per-share calculations
are based on the assumption that all dilutive convertible debentures are
converted into shares of common stock as of the beginning of the year, or as of
the issue date if later, and (i) that those shares are added to the weighted
average number of common shares and share equivalents outstanding used in the
calculation of primary earnings per share, and (ii) that after-tax income is
adjusted accordingly.
 
L.  TRANSLATION OF FOREIGN CURRENCIES
 
    The financial statements of the Company's foreign subsidiaries have been
translated into U.S. dollars in accordance with Statement of Financial
Accounting Standards ("SFAS") No. 52. Exchange gains and losses on forward
exchange contracts designated as hedges of foreign net investments are reported
as an adjustment to shareholders' equity. Currency translation adjustments and
the effect of transaction gains and losses and exchange gains and losses on
forward exchange contracts are insignificant for all years presented. At May 31,
1996, the Company had sold substantially all of its foreign operations.
 
NOTE 2. ACQUISITIONS AND DISPOSALS OF FACILITIES
 
  DOMESTIC
 
    In July 1995, the Company acquired a one-third interest (which subsequently
has been increased to a 50% interest) in the leased 82-bed St. Clair Hospital
located outside Birmingham, Alabama. In August 1995, the Company acquired
Memorial Medical Center (formerly known as Mercy+Baptist Medical Center), a
system of two general hospitals with an aggregate of 759 licensed beds located
in New Orleans, Louisiana, and a related physician practice. In September 1995,
the Company acquired Providence Memorial Hospital, a general hospital located in
El Paso, Texas. Providence is licensed for 471 general hospital beds (34 of
which may be used as skilled nursing beds) and is licensed for 30 additional
rehabilitation and sub-acute care beds. In October 1995, the Company entered
into a long-term lease of the 49-bed Medical Center of Manchester in central
Tennessee. In November 1995, the Company acquired the 104-bed Methodist Hospital
of Jonesboro, a general hospital located in Jonesboro, Arkansas. That hospital
is now owned by a limited liability company of which Tenet owns 95% and is the
manager. In fiscal 1996 the Company also acquired several other physician
practices and other healthcare operations. These acquisitions were all accounted
for as purchases. On June 1, 1996, the Company acquired Hialeah Hospital, a
378-bed acute care hospital in Hialeah, Florida. The Company also has entered
into a definitive agreement to purchase Lloyd Noland Hospital in Birmingham,
Alabama, which purchase the Company expects to complete prior to the end of the
second quarter of fiscal 1997.
 
    In March 1995, in a transaction accounted for as a purchase, the Company
acquired all the outstanding common stock of American Medical Holdings, Inc.
("AMH") for $1.5 billion in cash and 33,156,614 shares of the Company's common
stock valued at $488 million. The total purchase price was allocated to the
assets and liabilities of AMH based on their estimated fair values. The total
purchase price exceeded the fair value of the net assets acquired by
approximately $2.5 billion.
 
  INTERNATIONAL
 
    In June 1995, the Company sold two hospitals and related healthcare
businesses in Singapore for approximately $243 million, net of $78 million in
debt assumed by the buyer. In October 1995, the Company sold its interest in
Australian Medical Enterprises, Limited ("AME") for a net cash consideration of
approximately $68 million, and the Company sold its interest in a hospital in
Malaysia for net cash consideration of approximately $12 million. In February
1996, the Company also sold its 40% interest in a hospital in Thailand for net
cash consideration of approximately $21 million. These transactions resulted in

NOTE 2. ACQUISITIONS AND DISPOSALS OF FACILITIES (CONTINUED)
gains of approximately $158 million. The net proceeds from these sales were used
to repay secured bank loans under the Company's February 28, 1995 credit
agreement. Net operating revenues of the sold facilities were $202 million in
1995 and $51 million in 1996. Operating profits before general corporate
overhead costs were $39 million in 1995 and $7 million in 1996.
 
    In May 1996, the Company also sold its approximately 42% interest in
Westminster for a gain of $34 million. Pretax cash proceeds from this
transaction were approximately $120 million and were used to repay bank loans.
 
NOTE 3. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The carrying amounts of cash, accounts receivable, short-term borrowings and
notes, current portion of long-term debt, accounts payable and interest payable
approximate fair value because of the short maturity of these instruments. The
carrying values of investments, both short-term and long-term (excluding
investments accounted for by the equity method), long-term receivables and
long-term debt are not materially different from the estimated fair values of
these instruments. The estimated fair values of interest rate swap agreements
are not material to the Company's financial position.

  LOANS PAYABLE TO BANKS
 
    In March 1996, a syndicate of banks entered into a new, five-year $1.55
billion unsecured revolving credit agreement with the Company. The agreement
replaced the Company's $2.3 billion secured bank term loan and revolving credit
agreement dated February 28, 1995. Unamortized costs of issuance written off in
connection with the refinancing were $36 million. The write-off is reflected as
an extraordinary charge from early extinguishment of debt in the quarter ended
May 31, 1996 in the amount of $23 million, which is net of tax benefits of $13
million. The $2.3 billion in secured bank loans was used to finance the AMH
merger and repay existing indebtedness. The early extinguishment of debt in 1995
resulted in an extraordinary loss of $20 million, net of tax benefits of $12
million.
 
    Borrowings under the new agreement are unsecured and will mature on March 1,
2001. The Company generally may repay or prepay loans made under the agreement
and may reborrow at any time prior to such maturity date. The Company's unused
borrowing capacity under the new agreement was $575 million as of May 31, 1996.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 5. LONG-TERM DEBT AND LEASE OBLIGATIONS (CONTINUED)
    Loans under the new credit agreement generally bear interest at a base rate
equal to the prime rate or, if higher, the federal funds rate plus 0.50%, plus
an interest margin ranging from zero to 25 basis points, or, at the option of
the Company, an adjusted London interbank offered rate ("LIBOR") for one-, two-,
three- or six-month periods plus an interest margin of from 30 to 87.5 basis
points. The Company has agreed to pay the lenders under the new credit agreement
a facility fee on the total loan commitment at rates ranging from 15 to 37.5
basis points. The interest margins and facility fee rates are based on the
ratios of the Company's consolidated net earnings before interest, taxes,
depreciation and amortization ("EBITDA") to interest expense and the ratio of
the Company's consolidated total debt to EBITDA. During the three months ended
May 31, 1996 the weighted average interest rates on these borrowings was 6.1%.
 
  SENIOR NOTES AND SENIOR SUBORDINATED NOTES
 
    In connection with the AMH merger and related refinancing, the Company sold,
on March 1, 1995, $300 million of 9 5/8% Senior Notes due September 1, 2002 and
$900 million of 10 1/8% Senior Subordinated Notes due March 1, 2005. The
proceeds to the Company were $1.17 billion, after underwriting discounts and
commissions. The senior notes are not redeemable by the Company prior to
maturity. The senior subordinated notes are redeemable at the option of the
Company, in whole or from time to time in part, at any time after March 1, 2000,
at redemption prices ranging from 105.063% in 2000 to 100% in 2003 and
thereafter.
 
    The senior notes are unsecured obligations of the Company ranking senior to
all subordinated indebtedness of the Company, including the senior subordinated
notes, and pari passu in right of payment with all other indebtedness of the
Company, including borrowings under the new credit facility described above. The
senior subordinated notes also are unsecured obligations of the Company
subordinated in right of payment to all existing and future senior debt,
including the senior notes and borrowings under the new credit facility.
 
    In October 1995, the Company sold $500 million of Senior Notes due December
2003. The notes have a coupon of 8 5/8% and were priced at 99.666% of par to
yield 8.68%. In January 1996, the Company issued $320 million of 6% Exchangeable
Subordinated Notes due 2005 that will be exchangeable at the option of the
holder for shares of common stock of Vencor (see Note 12) at any time on or
after November 6, 1997 at an exchange rate of 25.9403 shares per $1,000
principal amount of the notes, subject to the Company's right to pay an amount
in cash equal to the market price of the shares of Vencor common stock in lieu
of delivery of such shares. The notes will be redeemable at the option of the
Company at any time on or after January 15, 1999 at the redemption prices set
forth in the indenture, plus accrued and unpaid interest. The net proceeds from
the notes sold in October 1995 and January 1996 were applied to repay secured
bank loans under the Company's February 28, 1995 credit agreement.
 
    If the fair market value of the Company's investment in common stock of
Vencor ever exceeds the carrying value of the notes, the Company will adjust the
carrying value of the notes to the fair market value of the investment through a
charge or credit to earnings. Corresponding adjustments to the carrying value of
the investment in Vencor will be credited or charged directly to shareholders'
equity as unrealized gains or losses.
 
  CONVERTIBLE FLOATING-RATE DEBENTURES
 
    All of the Company's Convertible Floating-Rate Debentures due in April 1996
were redeemed or converted prior to that date into shares of the Company's
common stock through the exercise of

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 5. LONG-TERM DEBT AND LEASE OBLIGATIONS (CONTINUED)
performance investment plan options purchased by key employees of the Company.
The performance investment plan options permitted the holder to purchase
debentures at 95% of their $105,264 face value. The debentures were convertible
into preferred stock, which, in turn, was convertible into common stock at an
exercise price equivalent to $15.83 per share. The proceeds from the conversions
during the year were used to repay bank loans under the Company's credit
agreements.
 
    During 1996, the Company reduced taxable income by the excess of the fair
market value of the stock obtained at the date of exercise over the principal
amount of the debentures redeemed. The resulting tax benefit of $20 million, was
credited to additional paid-in capital.
 
    As a result of the redemption and/or conversions of all of the Company's
convertible floating-rate debentures during fiscal 1996, at May 31, 1996 there
are no potentially dilutive securities except for employee stock options, which
are common stock equivalents for purposes of calculating earnings per share.
 
  UNSECURED MEDIUM-TERM NOTES
 
    The weighted average interest rates on the medium-term notes were 8.1% in
1994, 8.3% during 1995 and 9.0% during 1996.
 
  LOAN COVENANTS
 
    The new credit facility and the indentures governing the senior notes and
the senior subordinated notes have, among other requirements, limitations on
borrowings by, and liens on the assets of, the Company and its subsidiaries,
investments, the sale of all or substantially all assets and prepayment of
subordinated debt, a prohibition against the Company declaring or paying
dividends on or purchasing its stock unless its senior long-term unsecured debt
securities are rated BBB- or higher by Standard and Poor's Rating Services and
Baa3 or higher by Moody's Investors Service, Inc., and covenants regarding
maintenance of specified levels of net worth, debt ratios and fixed-charge
coverage ratios. Because of dividend restrictions, all of the Company's retained
earnings are restricted. The Company is in compliance with its loan covenants.
There are no compensating balance requirements for any credit line or borrowing.

NOTE 7. CLAIMS AND LAWSUITS
 
A.  PROFESSIONAL AND GENERAL LIABILITY INSURANCE
 
    In the normal course of business the Company is subject to claims and
lawsuits relating to injuries arising from patient treatment. The Company
believes that its liability for damages resulting from such claims and lawsuits
is adequately covered by insurance or is adequately provided for in its
consolidated financial statements.
 
    The Company insures substantially all of its professional and comprehensive
general liability risks in excess of self-insured retentions, which vary by
hospital and by policy period from $500,000 to $3 million per occurrence,
through an insurance company owned by several healthcare companies and in which
the Company has a majority equity interest. A significant portion of these risks
is, in turn, reinsured with major independent insurance companies. Through May
31, 1994, the Company insured its professional and comprehensive general
liability risks related to its psychiatric and rehabilitation hospitals through
a wholly-owned insurance subsidiary, which reinsured risks in excess of $500,000
with major independent insurance companies. The Company has reached the policy
limits provided by this insurance subsidiary related to the psychiatric
hospitals in certain years. In addition, damages, if any, arising from fraud and
conspiracy claims in psychiatric malpractice cases may not be insured.
 
    In addition to the reserves recorded by the above insurance subsidiaries,
the Company maintains an unfunded reserve based on actuarial estimates for the
self-insured portion of its professional liability risks. Reserves for losses
and related expenses are estimated using expected loss-reporting patterns and
have

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 7. CLAIMS AND LAWSUITS (CONTINUED)
been discounted to their present value using a weighted average discount rate of
approximately 9%. Adjustments to the reserves are included in results of
operations.
 
B.  SIGNIFICANT LEGAL PROCEEDINGS
 
    The Company has been involved in significant legal proceedings of an unusual
nature related principally to its psychiatric business. During the years ended
May 31, 1994, 1995 and 1996, the Company recorded provisions to estimate the
cost of the ultimate disposition of all of these proceedings and to estimate the
legal fees that it expected to incur. The Company has settled the most
significant of these matters. The remaining reserves for unusual litigation
costs that relate to matters that had not been settled as of May 31, 1996 and an
estimate of the legal fees to be incurred subsequent to May 31, 1996 represent
management's estimate of the remaining net costs of the ultimate disposition of
these matters. There can be no assurance, however, that the ultimate liability
will not exceed such estimates. Although, based upon information currently
available to it, management believes that the amount of damages, if any, in
excess of the reserves for unusual litigation costs that may be awarded in any
of the following unresolved legal proceedings cannot reasonably be estimated,
management does not believe it is likely that any such damages will have a
material adverse effect on the Company's results of operations, liquidity or
capital resources. All of the costs associated with these legal proceedings
except those relating to the AMH merger are classified in discontinued
operations.
 
    PSYCHIATRIC MALPRACTICE CASES  The Company continues to defend a greater
than normal level of litigation relating to certain of its subsidiaries' former
psychiatric operations. The majority of the lawsuits filed contain allegations
of medical malpractice as well as allegations of fraud and conspiracy against
the Company and certain of its subsidiaries and former employees. Also named as
defendants are numerous doctors and other healthcare professionals. The Company
believes that the increase in litigation stems, in whole or in part, from
advertisements by certain lawyers seeking former psychiatric patients in order
to file claims against the Company and certain of its subsidiaries. The
advertisements focus, in many instances, on the Company's settlement of past
disputes involving the operations of its psychiatric subsidiaries, including the
Company's 1994 resolution of the government's investigation and a corresponding
criminal plea agreement involving a psychiatric subsidiary of the Company. Among
the suits filed during fiscal 1995 were two lawsuits in Texas state court with
approximately 740 individual plaintiffs at present who purport to have been
patients in certain Texas psychiatric facilities. During fiscal 1996, 64
plaintiffs voluntarily withdrew from one of the lawsuits, and the Company's
motion to recuse the original trial judge in that lawsuit has been granted. In
the second lawsuit, the Texas Supreme Court has ruled that lead counsel for the
plaintiffs may not continue to represent the plaintiffs due to a conflict of
interest as asserted by the defendants. Neither of the two cases currently is
set for trial.
 
    During fiscal 1995 and 1996 lawsuits with approximately 210 individual
plaintiffs at present who purport to have been patients in certain Washington,
D.C. psychiatric facilities, containing allegations similar to those in the
Texas cases described above, were filed in the District of Columbia.
 
    In addition to the above, a purported class action was filed in Texas state
court in May 1995 also containing allegations of fraud and conspiracy similar to
those described in the preceding paragraphs. The plaintiff purports to represent
all persons who were voluntarily admitted to one of 11 psychiatric hospitals in
Texas between January 1, 1981, and December 31, 1991, and who also fit into one
or more of eight categories based on such factors as their age at the time of
admission, status of their insurance at the time of discharge and whether a
certain type of examination was conducted prior to their being admitted. In
February 1996, an insurance company that purports to have paid claims on behalf
of the potential class intervened in the action and the case was removed to the
U.S. District Court in Houston, Texas. A motion

NOTE 7. CLAIMS AND LAWSUITS (CONTINUED)
by the plaintiffs to remand the case to Texas state court currently is pending.
The class has not been certified and the Company believes that the class is not
capable of being certified.
 
    The Company expects that additional lawsuits with similar allegations will
be filed. The Company believes it has a number of defenses to each of these
actions and will defend the litigation vigorously. Until the lawsuits are
resolved, however, the Company will continue to incur substantial legal
expenses. At May 31, 1996, the reserves for unusual litigation costs related to
these actions primarily represent the estimated costs of defending the actions.
 
    SHAREHOLDER LAWSUITS  As a result of mediation, the parties in the
shareholder derivative and class action suits filed against the Company in 1991
agreed to a global settlement of all plaintiffs' claims. Pursuant to the
settlement, which was approved by the court in January 1996, a total of $63.75
million plus interest was paid by or on behalf of the defendants. Of this
amount, Tenet's directors' and officers' liability insurance ("D&O") carriers
paid a total of $32.5 million plus interest on behalf of the individual
defendants. In addition, one of the D&O carriers reimbursed the Company for $5.5
million in attorneys' fees expended on the litigation.
 
    Two additional federal class actions filed in August 1993 were consolidated
into one action. This consolidated action is on behalf of a purported class of
shareholders who purchased or sold stock of the Company between January 14, 1993
and August 26, 1993, and alleges violations of securities laws by the Company
and certain of its executive officers. After unsuccessful mediation, the parties
agreed in May 1995 to proceed with the litigation. In June 1995, the defendants
filed a motion to dismiss and to strike plaintiffs' complaint, which motion is
still pending.
 
C.  LITIGATION RELATING TO THE AMH MERGER
 
    A total of nine purported class actions were filed challenging the merger in
both Delaware and California. In April 1996, the parties to the class actions
executed a stipulation of settlement, and the court has issued an order
approving the settlement. Under the terms of that settlement, the Company agreed
to pay $350,000 for the plaintiffs' attorneys fees and agreed that for a period
of one year following final approval of the settlement it will not engage in any
transaction that will be dilutive to existing shareholders without that
transaction being approved by a majority of its outside directors.
 
NOTE 8. PREFERRED STOCK PURCHASE RIGHTS AND PREFERRED STOCK
 
    In 1988 the Company distributed Preferred Stock Purchase Rights to holders
of the Company's common stock and authorized the issuance of additional rights
for common stock issued after that date. The rights expire in December 1998
unless previously exercised or redeemed and do not entitle the holders thereof
to vote as shareholders or receive dividends.
 
    The Company may redeem the rights at $.025 per right at any time up to the
10th business day after a public announcement that a person has acquired 20% or
more of the Company's common stock in a transaction or transactions not approved
by the Board of Directors. The rights are not exercisable until after the date
on which the Company's right to redeem the rights has expired. When exercisable,
each right entitles the holder thereof to purchase from the Company one
two-thousandth of a share of Series A Junior Participating Preferred Stock
("Series A Preferred Stock") at a price of $40.61, subject to adjustment.
 
    Subject to the foregoing, in the event the Company is acquired in a merger
or other business combination transaction in which shares of the Company's
common stock are exchanged for shares of another company or more than 50% of the
Company's assets are sold, each holder of a right generally will

be entitled upon exercise to purchase, for the then-current exercise price of
the right, common stock of the surviving company having a market value equal to
two times the exercise price of the rights. The plan also provides that, in the
event of certain other mergers or business combinations, certain self-dealing
transactions or the acquisition by a person of stock having 30% or more of the
Company's general voting power, each holder of a right generally will be
entitled upon exercise to purchase, for the then-current exercise price of the
right, the number of shares of Series A Preferred Stock having a market value
equal to two times the exercise price of the rights.
 
    The Series A Junior Participating Preferred Stock for which the Preferred
Stock Purchase Rights may be exchanged is nonredeemable and has a par value of
$0.15 per share. None of the 225,000 authorized shares are outstanding.
 
NOTE 9. STOCK BENEFIT PLANS
 
    Under the Company's 1983, 1991 and 1995 stock incentive plans, stock options
and incentive stock awards have been made to certain officers and other key
employees. Stock options generally are granted at an exercise price equal to the
fair market value of the Company's shares on the date of grant and are normally
exercisable at the rate of one-third per year beginning one year from the date
of grant. Stock options generally expire 10 years from the date of grant. No
incentive stock awards have been granted since 1994.
 
    All awards granted under the 1983, 1991 and 1995 plans will vest under
circumstances defined in the plans or under certain employment arrangements,
including, with the consent of the Compensation and Stock Option Committee of
the Board of Directors, upon a change in control of the Company.
 
    Charges to continuing operations associated with these stock benefit plans
were $12 million in fiscal 1994, $4 million in 1995, and $2 million in 1996.
 
    New stock awards may be made only under the 1991 and 1995 plans. At May 31,
1996, there were 295,647 shares of common stock available under the 1991 plan
and 9,137,472 shares available under the 1995 plan for future awards. The table
below summarizes the transactions in all stock option plans in which employees

    In September 1994 a new 1994 Directors Stock Option Plan replaced a 1991
Director Restricted Share Plan which replaced a 1985 Director Stock Option Plan.
Awards previously made under the 1985 and 1991 plans remain outstanding, but new
awards are made only under the 1994 plan. The plan makes available for issuance
to nonemployee directors options to purchase 500,000 shares of common stock.
Under the plan each nonemployee director will receive a stock option for 5,000
common shares upon initially being elected to the Board of Directors and on each
January thereafter. Awards will have an exercise price equal

to the fair market value of the Company's shares on the date of grant, will vest
one year after the date of grant and will expire 10 years after the date of
grant. At May 31, 1996, there were options outstanding under the Directors plans
for 322,820 shares of common stock at exercise prices of $8.67 to $21.50 per
share.
 
    In November 1995, the Financial Accounting Standards Board (FASB) issued
SFAS No. 123-- "Accounting for Stock-Based Compensation," which establishes a
new accounting standard for the measurement and recognition of stock-based
awards to employees and others. This standard permits entities to continue to
account for stock-based awards using present standards prescribed by APB Opinion
No. 25--"Accounting for Stock Issued to Employees." The Company has elected to
continue using the provisions of APB Opinion No. 25 in accounting for its
stock-based awards. Under this option, however, the Company will be required to
disclose the pro forma effect of stock-based awards on net income and earnings
per share as if SFAS No. 123 had been adopted. The disclosure requirements of
SFAS No. 123 are effective for fiscal years beginning after December 15, 1995.
The pro forma disclosures will include the effect of all awards granted in
fiscal years that began after December 15, 1994.
 
NOTE 10. EMPLOYEE STOCK PURCHASE PLAN
 
    On September 27, 1995, the Company's shareholders approved its 1995 Stock
Purchase Plan under which the Company is authorized to issue up to 2,000,000
shares of common stock to eligible employees of the Company or its designated
subsidiaries who customarily work at least 20 hours per week and six months per
year. Under the terms of the plan, employees can elect to have between 1% and
10% of their base earnings withheld each calendar quarter to purchase, on the
last day of the quarter, shares of the Company's common stock at a purchase
price equal to 85% of the lower of the closing price on the first day of the
quarter or its closing price on the last day of the quarter. The plan commenced
on April 1, 1996. Under the plan, the Company sold 114,876 shares to 3,666
employees on June 30, 1996 at a price of $17.85 per share.
 
NOTE 11. EMPLOYEE RETIREMENT PLANS
 
    Substantially all domestic employees who are employed by the Company or its
subsidiaries, upon qualification, are eligible to participate in a defined
contribution 401(k) plan. Employees who elect to participate make contributions
of from 1% to 16% of their eligible compensation, and the Company matches such
contributions up to a maximum of 3% of eligible compensation. Company
contributions to the plans for fiscal 1996 were approximately $27 million, they
were $17 million in each of 1994 and 1995.
 
    Substantially all employees who were employed by AMI prior to the merger
were eligible to participate in one of AMI's defined benefit pension plans (the
"AMI Plans"). The benefits under the plans are based on years of service and the
employee's base compensation as defined in the AMI Plans. The Company's policy
is to fund pension costs accrued within the limits allowed under federal income
tax regulations. Contributions are intended to provide not only for benefits
attributed to credited service to date, but also for those expected to be earned
in the future. Effective December 31, 1995, the AMI Plans were frozen. As of
that date, participants under the AMI Plans ceased accruing new benefits and the
AMI Plans ceased accepting new participants. The Company continues to fund
benefits accrued prior to that date.

    Net pension cost for the AMI Plans was $2 million and $4 million for the
three months ended May 31, 1995 and for the year ended May 31, 1996,
respectively. The discount rate used in determining the actuarial present value
of the projected benefit obligation for the AMI Plans approximated 7.0% at May
31, 1995 and 8.0% as of May 31, 1996. The Company does not have a plan that
provides any postretirement benefits other than pensions to retired employees.
 
NOTE 12. INVESTMENTS
 
    In September 1995, Vencor acquired all of the outstanding common stock of
Hillhaven. As a result of the transaction, the shares of Hillhaven common stock
that had been owned by the Company were exchanged for 8,301,067 shares of Vencor
common stock. In addition, the Company received approximately $92 million in
cash for its Hillhaven Series C and Series D preferred stock. The exchange and
sale of preferred stock resulted in a gain of approximately $176 million. The
Company's investment in Hillhaven previously had been accounted for under the
equity method. Following the exchange, the Company owned less than 20% of
Vencor's common stock and began to account for its investment in Vencor common
stock in accordance with SFAS No. 115 "Accounting for Certain Investments in
Debt and Equity Securities." The Company classifies such securities as
"available for sale" whereby the carrying value of the unrestricted Vencor
shares will be adjusted to market value at the end of each accounting period
through a credit or charge, net of income taxes, to shareholders' equity. At May
31, 1996, the market value of the investment was approximately $263 million.
(See Note 5)
 
    The Company is contingently liable under various guarantees for $146 million
of Vencor's obligations to third parties, including $139 million of lease
obligations and $7 million of long-term debt obligations. The Company is also
contingently liable for approximately $75 million in lease obligations relating
to certain rehabilitation facilities sold in 1994.
 
    In August 1994, the Company completed the sale of a controlling interest in
TRC, an operator of outpatient renal dialysis centers. This transaction resulted
in a $32 million gain to the Company. As part of the transaction, the Company
also received a $75 million cash distribution from TRC prior to the sale and
retained an approximate 25% minority interest. In October 1995, TRC completed an
initial public offering of 6,000,000 shares of its common stock, which resulted
in an additional gain to the Company of

NOTE 12. INVESTMENTS (CONTINUED)
approximately $17 million in fiscal 1996. The Company's ownership interest was
reduced to approximately 11.6% as a result of a secondary offering by TRC in
April 1996.
 
    Because the Company owned less than 20% of the common shares after the
October 1995 stock sale by TRC, and does not exercise significant influence over
TRC, the Company began accounting for its investment in accordance with SFAS No.
115. At May 31, 1996, the Company's carrying value in its investment in TRC was
$49 million and the market value of this investment was approximately $124
million.
 
NOTE 13. IMPAIRMENT LOSSES
 
    In March 1995, the FASB issued SFAS No. 121--"Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to be Disposed Of." The statement
is effective for fiscal years beginning after December 15, 1995, but the Company
has elected to adopt it for the year ended May 31, 1996. Accordingly, the
Company recorded, in the fourth quarter of fiscal 1996, an impairment loss of
approximately $86 million, before tax benefits of approximately $32 million
($0.25 per fully diluted share). The assets deemed to be impaired consist of
three rehabilitation hospitals, four general hospitals and a parcel of
undeveloped land. Two of the seven facilities are being held for sale. In the
case of the rehabilitation hospitals, the principal facts and circumstances
leading to the impairment include recent and forecast reductions in hospital
admissions and payment rates caused by payor-driven shifts in care from
traditional rehabilitation services to skilled nursing facilities. The
impairment of the general hospitals is the result of (i) a change in the use of
one of the facilities from acute care to less-intense specialty care, (ii) lower
patient volumes, and (iii) adverse changes in payor mix.
 
    In determining the amount of the impairment loss, the assets' fair values
were determined by specific market appraisals, reference to recent sales prices
of comparable facilities, either on a per-bed or earnings multiple basis, or by
the present values of discounted expected future cash flows. The two facilities
held for sale had operating losses aggregating $5 million in fiscal 1996, have
carrying amounts totaling $34 million as of May 31, 1996 and are expected to be
sold by December 31, 1996.
 
NOTE 14. RESTRUCTURING CHARGES
 
    In connection with the AMH merger, the Company relocated substantially all
of its hospital support activities previously located in Southern California and
Florida to the former corporate headquarters of AMH located in Dallas, Texas.
Severance payments and outplacement services for involuntary terminations of
approximately 890 former employees and other related costs in connection with
this move were estimated to be $37 million ($0.12 per fully diluted share) and
were classified as restructuring charges in the accompanying consolidated
statements of operations for the year ended May 31, 1995.
 
    During the fourth quarter of fiscal 1994, the Company initiated a plan to
significantly decrease overhead costs through a reduction in corporate and
division staffing levels and to review the resulting office space needs of all
corporate operations. The Company decided to sell its Santa Monica, California,
corporate headquarters building and to lease substantially less office space in
that building or at an alternative site. Costs of the write-down of the
building, employee severance benefits for approximately 110 employees and other
expenses directly related to the overhead reduction plan were estimated to be
approximately $77 million. The Company's corporate headquarters were moved to
new leased office space in Santa Barbara, California, in May 1996 and the former
headquarters building was sold the following month.

NOTE 14. RESTRUCTURING CHARGES (CONTINUED)
    Actual costs incurred and charged against the restructuring reserves were
approximately $35 million in 1994, $23 million in 1995 and $32 million in 1996.
The balances of the reserves are included in other current liabilities or other
long-term liabilities in the Company's consolidated balance sheets at May 31,
1995 and 1996.
 
NOTE 15. DISCONTINUED OPERATIONS--PSYCHIATRIC HOSPITAL BUSINESS
 
    In November 1993, the Company decided to discontinue its psychiatric
hospital business and adopted a plan to dispose of its psychiatric hospitals and
substance abuse recovery facilities. The consolidated statements of operations
reflect the operating results of the discontinued business separately from
continuing operations. All operating results and gains or losses on disposals of
facilities for the discontinued business for periods subsequent to November 30,
1993, have been charged to the reserve for estimated losses during the phase-out
period, except for the following: (i) in the fourth quarter of fiscal 1995, the
Company recorded an additional $16 million of estimated litigation costs (less
income tax benefits of $7 million) and (ii) in the fourth quarter of fiscal
1996, the Company recorded $16 million (less income tax benefits of $6 million)
for additional estimated legal costs and $25 million (less tax benefits of $10
million) to increase the reserves of the Company's wholly-owned insurance
subsidiary for professional liability claims, all of which related to the former
psychiatric hospitals.
 
    Net operating revenues for the discontinued operations for fiscal 1994 were
$476 million. Losses from operations during the year were $266 million, before
income tax benefits of $111 million. In fiscal 1994, the Company recognized a
charge for estimated losses upon disposal amounting to $414 million, including
$379 million of costs to settle federal and state investigations and other
unusual legal costs related to the psychiatric hospital business, along with
$433 million of estimated operating losses during the phase-out period, less tax
benefits of $301 million. By May 31, 1995, substantially all of the assets of
the discontinued operations had been sold.
 
NOTE 16. DERIVATIVE FINANCIAL INSTRUMENTS
 
    The Company has only limited involvement with derivative financial
instruments and does not use them for trading purposes. These derivatives are
nonleveraged and involve little complexity. They are used to manage well-defined
interest risks. The notional amounts of derivatives in the tables below do not
represent amounts exchanged by the parties and, thus, are not a measure of the
exposure of the Company through its use of derivatives. There are no cash or
collateral requirements in connection with these agreements.
 
    INTEREST RATE SWAPS  These derivative financial instruments allow the
Company to make long-term borrowings at floating rates and then swap them into
fixed rates that are lower than those available to the Company if fixed-rate
borrowings were made directly. Under interest rate swaps, the Company agrees
with other parties to exchange, at specified intervals, the difference between
fixed-rate and floating-rate interest amounts calculated by reference to an
agreed notional principal amount. Cross-currency interest rate swaps allow
borrowings to be made in foreign currencies, gaining access to additional
sources of financing while limiting foreign exchange risk. The Company's
exposure to credit loss under these agreements is limited to the interest rate
spread in the event of nonperformance by the other parties. Because the other
parties are creditworthy financial institutions, generally commercial banks, the
Company does not expect nonperformance.

                 TENET HEALTHCARE CORPORATION AND SUBSIDIARIES
 
         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
1.  The unaudited financial information furnished herein, in the opinion of
    management, reflects all adjustments that are necessary to fairly state the
    financial position of Tenet Healthcare Corporation, its cash flows and the
    results of its operations for the periods indicated. All the adjustments
    affecting net income are of a normal recurring nature.
 
   The Company presumes that users of this interim financial information have
    read or have access to the Company's audited financial statements and
    Management's Discussion and Analysis of Financial Condition and Results of
    Operations for the preceding fiscal year and that the adequacy of additional
    disclosure needed for a fair presentation may be determined in that context.
    Accordingly, footnotes and other disclosure which would substantially
    duplicate the disclosure contained in the Company's most recent annual
    report to security holders have been omitted. The patient volumes and net
    operating revenues of the Company's domestic general hospitals are subject
    to seasonal variations caused by a number of factors, including but not
    necessarily limited to, seasonal cycles of illness, climate and weather
    conditions, vacation patterns of both hospital patients and admitting
    physicians and other factors relating to the timing of elective hospital
    procedures. Net income also is not necessarily representative of operations
    for a full year for various reasons, including interest rates, acquisitions
    and disposals of facilities and long-term assets, revenue allowances and
    discount fluctuations, the timing of price changes and fluctuations in
    quarterly tax rates. These same considerations apply to all year-to-year
    comparisons.
 
2.  The Company's net operating revenues consist primarily of net patient
    service revenues, which are based on established billing rates less
    applicable allowances and discounts. These allowances and discounts,
    primarily for patients covered by Medicare, Medicaid and other contractual
    programs, amounted to $1.4 billion and $1.7 billion for the three-month
    periods ended August 31, 1995 and 1996, respectively.
 
3.  During the three-month period ended August 31, 1996, actual costs incurred
    and charged against the Company's reserves for discontinued operations were
    approximately $13.5 million. Costs incurred and charged against
    restructuring reserves were approximately $3.1 million. These reserves are
    included in other current liabilities or other long-term liabilities in the
    Company's balance sheets at May 31, 1996 and August 31, 1996.
 
4.  During the quarter ended August 31, 1996, the Company acquired Hialeah
    Hospital, a 378-bed acute care hospital in Hialeah, Florida for $67.1
    million in cash. The Company also acquired several physician practices
    during the quarter. All of these transactions were accounted for as
    purchases. The results of operations of the acquired businesses have been
    included in the Company's Consolidated Statements of Income from the dates
    of acquisition. On October 4, 1996, the Company acquired the Lloyd Noland
    Hospital, a 319-bed acute care hospital in Birmingham, Alabama.
 
5.  As a result of the redemption and/or conversion of all of the Company's
    convertible subordinated floating-rate debentures during the year ended May
    31, 1996, there are no potentially dilutive securities except for employee
    stock options. Consequently, primary and fully-diluted earnings per share
    for the quarter ended August 31, 1996 are the same. Fully-diluted earnings
    per share for the quarter ended August 31, 1995 include the effects of the
    convertible subordinated floating-rate debentures which were outstanding
    during the period.
 
6.  On August 30, 1996 the Company announced that it would redeem all of its
    then outstanding 11% Senior Notes due 2000 for $1,031.40 per $1,000
    principal amount, on October 15, 1996, and pay accrued interest of $55.00
    per original principal amount through the redemption date.

7.  There have been no material changes to the description of i) Professional
    and General Liability Insurance set forth in Note 7A or ii) Significant
    Legal Proceedings set forth in Note 7B of Notes to Consolidated Financial
    Statements incorporated by reference in the Company's annual report on Form
    10-K for the year ended May 31, 1996. Although, based upon information
    currently available to it, management believes that the amount of damages,
    if any, in excess of the reserves for unusual litigation costs that may be
    awarded in any of the unresolved legal proceedings cannot reasonably be
    estimated, management does not believe it is likely that any such damages
    will have a material adverse effect on the Company's results of operations,
    liquidity or capital resources.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors and Shareholders
OrNda HealthCorp
 
    We have audited the accompanying consolidated balance sheets of OrNda
HealthCorp and Subsidiaries as of August 31, 1995 and 1996, and the related
consolidated statements of operations, shareholders' equity, and cash flows for
each of the three years in the period ended August 31, 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
OrNda HealthCorp and Subsidiaries at August 31, 1995 and 1996, and the
consolidated results of operations and cash flows for each of the three years in
the period ended August 31, 1996, in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                                AUGUST 31, 1996
 
NOTE 1--GENERAL AND ACCOUNTING POLICIES
 
    REPORTING ENTITY:  OrNda HealthCorp ("Company"), which is incorporated in
the State of Delaware, is a provider of health care services through the
operation of general acute care hospitals located primarily in the southern and
western United States. Of the 49 general acute care hospitals operated by the
Company at August 31, 1996, 19 hospitals are located in California of which 17
hospitals are located in the southern California area. In addition, 5 hospitals
are located in southern Florida and 6 hospitals are located in Arizona. The
concentration of hospitals in California, southern Florida and Arizona increases
the risk that any adverse economic, regulatory or other developments that may
occur in such areas may adversely affect the Company's operations or financial
condition.
 
    CONSOLIDATION:  The consolidated financial statements include the accounts
of the Company, its majority owned subsidiaries and limited liability
corporations and partnerships in which the Company or one of its subsidiaries is
a general partner and has a controlling interest. Limited partner distributions
are shown as "minority interests" in the Consolidated Statements of Operations.
All material intercompany accounts and transactions have been eliminated in
consolidation. Certain prior year amounts have been reclassified to conform to
the current year presentation. The results of hospital operations acquired in
purchase transactions are included from their respective acquisition dates.
 
    USE OF ESTIMATES IN FINANCIAL STATEMENTS:  Judgment and estimation is
exercised by management in certain areas of the preparation of financial
statements. Some of the more significant areas include the allowance for
uncollectible accounts, settlement amounts due to or receivable from fiscal
intermediaries, reserves for self-insurance risks, and reserves for litigation.
Management believes that such estimates are adequate.
 
    TOTAL REVENUE:  Total revenue represents net patient service revenue and
other revenue and is reported at the net realizable amounts due from patients,
third-party payors, and others for services rendered. Net patient service
revenue generated from Medicare and Medicaid/Medi-Cal reimbursement programs
accounted for approximately 57%, 51% and 52% of total net patient service
revenue for the years ended August 31, 1994, 1995 and 1996, respectively.
Settlement amounts due to or receivables from Medicare and Medicaid/Medi-Cal
programs are determined by fiscal intermediaries. The difference between the
final determination and estimated amounts accrued is accounted for as an
adjustment to revenue in the year of final determination. Management believes
that adequate provision has been made in the consolidated financial statements
for potential adjustments resulting from such examinations. Recapture amounts
due to or receivable from the Medicare program are determined by fiscal
intermediaries. The difference between the final determination and estimated
amounts accrued for recapture related to sold facilities is accounted for as an
adjustment to gain or loss on asset sales in the year of final determination.
Management believes that adequate provision has been made in the consolidated
financial statements for potential adjustments resulting from examinations of
such recapture amounts.
 
    As stated above, the Company derives a substantial portion of its revenue
from the Medicare and Medicaid/Medi-Cal programs. Changes in existing
governmental reimbursement programs in recent years have resulted in reduced
levels of reimbursement for health care services. Additional changes are
anticipated which are likely to result in further reductions in the rate of
increase in reimbursement levels.
 
    EARNINGS (LOSS) PER COMMON SHARE:  Earnings (loss) per common and common
equivalent share is based on the Company's weighted average number of shares of
common stock outstanding during the year adjusted to give effect to dilutive
stock options and warrants using the treasury stock method. The dilutive

NOTE 1--GENERAL AND ACCOUNTING POLICIES (CONTINUED)
effect of stock options and warrants was 1.1 million shares in fiscal 1995 and
1.9 million shares in fiscal 1996. The effect of stock options and warrants was
anti-dilutive for fiscal 1994.
 
    Earnings (loss) per share assuming full dilution also assumes the conversion
of the Company's redeemable convertible preferred stock into common shares in
fiscal 1995 and 1996. The effect of the redeemable convertible preferred stock
was anti-dilutive in fiscal 1994.
 
    CASH AND CASH EQUIVALENTS:  For purposes of the Consolidated Statements of
Cash Flows, the Company considers all highly liquid debt instruments with a
maturity of three months or less when purchased to be cash equivalents. The
carrying amount reported in the balance sheet for cash and cash equivalents
approximates fair value.
 
    SUPPLIES:  Supplies are priced at cost (first-in, first-out method) and are
not in excess of market.
 
    PROPERTY, PLANT AND EQUIPMENT:  Depreciation is computed using the
straight-line method over the estimated useful lives of the assets. The range of
useful lives estimated for buildings and improvements is 10 to 40 years, and for
equipment and fixtures is 3 to 25 years. Assets related to capital leases
including improvements are amortized on a straight-line basis over the terms of
the leases or the useful lives of the assets, whichever is shorter and the
amortization expense is included with depreciation expense. Buildings and
Improvements include construction in progress of $27.2 million and $31.0 million
at August 31, 1995 and 1996, respectively. The Company capitalized interest
costs of $1.3 million, $1.3 million and $1.5 million related to construction in
progress for the years ended August 31, 1994, 1995 and 1996, respectively.
 
    INTANGIBLE ASSETS:  Deferred financing costs of $29.8 million and $28.1
million at August 31, 1995 and 1996, respectively, are included in Other Assets
in the accompanying Consolidated Balance Sheets and are amortized over the life
of the related debt using the effective interest method. Deferred financing
costs are net of accumulated amortization of $7.1 million and $12.6 million at
August 31, 1995 and 1996, respectively.
 
    Goodwill is amortized on a straight line basis and the amortization period
(20 to 40 years for hospitals and 5 to 10 years for non-hospital acquisitions)
is based upon the estimated economic lives of the hospital buildings acquired
which range from 25 to 40 years as determined by independent appraisers, the
indefinite useful life of any Certificates of Need acquired and competition
within the local markets. Goodwill is net of accumulated amortization of $15.9
million and $30.8 million at August 31, 1995 and 1996, respectively. The
carrying value of goodwill is reviewed by the Company on a quarterly basis if
the facts and circumstances suggest that it may be impaired. Factors considered
in evaluating impairment include unexpected or adverse changes in the following:
(i) the economic, competitive or regulatory environments in which the Company
operates, (ii) profitability and (iii) cash flows. If the review indicates that
goodwill will not be recoverable, as determined based on the undiscounted cash
flows of the entity acquired over the remaining amortization period, the
Company's carrying value of the goodwill is reduced by the estimated shortfall
of cash flows.
 
    IMPAIRMENT OF LONG-LIVED ASSETS:  In March 1995, the Financial Accounting
Standards Board issued
Financial Accounting Standard No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" (SFAS No. 121),
which requires impairment losses to be recorded on long-lived assets used in
operations when indicators of impairment are present and the undiscounted cash
flows estimated to be generated by those assets are less than the assets'
carrying amount. SFAS No. 121 also addresses the accounting for long-lived
assets that are expected to be disposed of. The

NOTE 1--GENERAL AND ACCOUNTING POLICIES (CONTINUED)
Company currently plans to adopt SFAS No. 121 in the first quarter of fiscal
1997 and, based on current circumstances, does not believe the effect of
adoption will be material.
 
    PROFESSIONAL LIABILITY INSURANCE:  At August 31, 1994, 1995 and 1996, the
general and professional liability risks of the Company were self-insured up to
$3.0 million on a per-occurrence basis and up to $30.0 million on an
aggregate-per-claim-year basis. At August 31, 1996, the Company carried general
and professional liability insurance from an unrelated commercial carrier for
losses above the self-insurance limits to $50.0 million. Liabilities for
self-insured professional and general liability risks at August 31, 1996, for
both asserted and unasserted claims, are based on actuarially projected
estimates discounted at an average rate of 8.0% to their present value based on
historical loss payment patterns. Although the ultimate settlement of these
liabilities may vary from such estimates, management believes the amount
provided in the Company's financial statements is adequate.

FISCAL 1994
 
  AHM
 
    On April 19, 1994, the Company completed a merger with American Healthcare
Management, Inc. ("AHM"), a health care services company engaged in the
operation of general acute care hospitals. AHM owned or leased 16 hospitals in 9
states, with a total of 2,028 licensed beds. The AHM Merger was accounted for as
a pooling of interests in which shareholders of AHM received 0.6 of a share of
the Company's common stock, representing 16.6 million additional shares issued,
in exchange for each share of AHM common stock held. In connection with the AHM
Merger, the Company recorded $30.0 million of nonrecurring charges and an
extraordinary loss of $8.4 million as a result of refinancing OrNda's and AHM's
senior credit facilities. Prior to the AHM Merger, AHM used a fiscal year ending
December 31. Accordingly, the recast operating results of AHM for the year ended
September 30, 1993, were combined with the operating results of OrNda for the
year ended August 31, 1993, and the AHM balance sheet accounts at September 30,
1993, were combined with OrNda's balance sheet accounts at August 31, 1993, in
order to restate the accompanying financial statements for periods prior to the
AHM Merger. As a result of this restatement, an adjustment for AHM's net income
for the month of September 1993 is reflected as a 1994 adjustment to the
consolidated retained earnings (deficit) and the Consolidated Statement of Cash
Flows for fiscal 1994 includes an adjustment to the balance at the beginning of
the period for AHM's cash activity for the month of September 1993. The effect
of the differing fiscal years on the Company's financial statements is not
significant.

OrNda and AHM included in the Consolidated Statements of Operations (in

    The AHM Merger caused an "ownership change" within the meaning of Section
382(g) of the Internal Revenue Code for both OrNda and AHM. Consequently,
allowable federal deductions relating to NOL's of OrNda and AHM arising in
periods prior to the AHM Merger are thereafter subject to annual limitations of
approximately $19 million and $16 million for OrNda and AHM, respectively. In
addition, approximately $55 million of the NOL's are subject to an annual
limitation of approximately $3 million due to prior "ownership changes" of
OrNda. The annual limitations may be increased in order to offset certain
built-in gains which are recognized during the five year period following an
ownership change. In addition, the NOL's from pre-merger tax years of AHM may
only be applied against the prospective taxable income of the AHM entities. The
limitations described above are not currently expected to significantly affect
the ability of the Company to ultimately recognize the benefit of these NOL's in
future years.
 
    The Company's federal income tax returns are not presently under audit by
the Internal Revenue Service (the "IRS"), except in respect to Summit as
disclosed below. Furthermore, the Company's federal income tax returns for
taxable years through August 31, 1991 are no longer subject to IRS audit, except
for net operating loss and credit carry forwards for income tax purposes from
prior years which may be subject to IRS audit as net operating loss and credit
carry forwards are utilized in subsequent tax years. Also, Summit Health has
extended the statute of limitations for fiscal years 1987 to 1992 through March
31, 1997.
 
    In recent years the IRS was examining the federal income tax returns for
fiscal years 1984, 1985 and 1986 of Summit Health, which became a wholly-owned
subsidiary of the Company in April 1994 and merged into the Company in September
1994. Summit Health received a revenue agent's report from the IRS with proposed
adjustments for the years 1984 through 1986 aggregating as of August 31, 1996
approximately $16.6 million of income tax, $66.4 million of interest on the tax,
$43.9 million of penalties

and $25.6 million of interest on the penalties. After receiving the revenue
agent's report, Summit Health filed a protest contesting the proposed
adjustments. On October 28, 1996, the Company entered into a Closing Agreement
on Final Determination with the IRS for the above audit period, by agreeing and
paying additional tax of $647,000 and interest of $888,000 to close the audit of
Summit Health for the fiscal years 1984 through 1986. The Closing Agreement is
subject to review by the Joint Congressional Committee on Taxation since the
matter relates to a refund of taxes to Summit Health in excess of $1 million.

SENIOR CREDIT FACILITIES
 
    On October 27, 1995, the Company executed an amended and restated credit
agreement (the "Restated Credit Facility") which increased the Company's
borrowing capacity under its credit facility from approximately $660.0 million
to $900.0 million, of which $692.2 million was outstanding on August 31, 1996
and of which commitment availability had been reduced by issued letters of
credit of $27.4 million and scheduled principal payments of $33.8 million,
resulting in available credit of $146.6 million. The Restated Credit Facility,
which amends the Company's previous credit agreement dated April 19, 1994, will
mature on October 30, 2001, and consists of the following facilities (the
"Senior Credit Facilities"): (i) revolving commitment of $440.0 million to
refinance the debt under the previous credit agreement, for general corporate
purposes, to issue up to $50 million of letters of credit, and for strategic
acquisitions; and (ii) a $460.0 million term loan to refinance debt under the
previous credit agreement payable in incremental quarterly installments.
 
    Loans under the Restated Credit Facility bear interest, at the option of the
Company, at a rate equal to either (i) the "alternate base rate" plus 0.25% or
(ii) LIBOR plus 1.25%, in each case subject to potential decreases or increases
dependent on the Company's leverage ratio. Interest is payable quarterly if a
rate based on the alternate base rate is elected or at the end of the LIBOR
period (but in any event not to exceed 90 days) if a rate based on LIBOR is
elected. The weighted average interest rate on the Company's borrowings under
the Senior Credit Facilities at August 31, 1996, was 6.7%.
 
    In certain circumstances, the Company is required to make principal
prepayments on the Senior Credit Facilities, including the receipt of proceeds
from the issuance of additional subordinated indebtedness, certain asset sale
proceeds not used to acquire additional assets within a specified period, and
50% of the proceeds in excess of $50 million from the issuance of additional
equity not used to acquire additional assets, fund capital expenditures or repay
subordinated debt within one year. The Company may prepay at any time all or
part of the outstanding Senior Credit Facilities without penalty.

NOTE 5--LONG-TERM DEBT (CONTINUED)
    The Restated Credit Facility limits, under certain circumstances, the
Company's ability to incur additional indebtedness, sell material assets,
acquire the capital stock or assets of another business, or pay dividends. The
Restated Credit Facility also requires the Company to maintain a specified net
worth and meet or exceed certain coverage, leverage, and indebtedness ratios.
Indebtedness under the Restated Credit Facility is secured by a perfected, first
priority security interest in the stock of all existing and future subsidiaries
of the Company, intercompany notes of indebtedness, majority-owned partnerships
and certain specified investments.
 
12.25% SENIOR SUBORDINATED NOTES
 
    In May 1992, OrNda issued $400 million aggregate principal amount of 12.25%
senior subordinated notes due May 2002 ( the "12.25% Notes"). The 12.25% Notes
are subordinated to the Company's Senior Credit Facilities and to indebtedness
of the Company's subsidiaries. Interest on the 12.25% Notes is payable
semiannually on May 15 and November 15, commencing November 15, 1992. The 12.25%
Notes mature on May 15, 2002, but may be redeemed in whole or in part at the
option of the Company on or after June 1, 1997 through June 1, 2000, at

    On July 28, 1993, AHM issued $100 million aggregate principal amount of 10%
senior subordinated notes due July 2003 (the "10% Notes"). Interest on the 10%
Notes is payable semiannually on February 1 and August 1 of each year. The 10%
Notes mature on August 1, 2003, but may be redeemed in whole or in part at the
option of the Company on or after August 1, 1998 through July 1, 2000 at
specified redemption prices in excess of par and thereafter at par.
 
    Pursuant to the Waiver and Consent Agreement dated February 3, 1994, by and
among the Company and the holders of a majority in principal amount of the 10%
Notes, as consideration for their agreement to make certain changes to the
Notes' Indenture to effect the AHM Merger (see Note 2) and other matters, the
Company (i) paid to the holders on the closing date of the AHM Merger $15.00 for
each $1,000 principal amount of outstanding 10% Notes and (ii) increased the
rate of interest on the 10% Notes from 10% per annum to 10.25% per annum
(redefined as the "10.25% Notes"). The AHM Merger caused a "change of control,"
as defined in the Notes' Indenture, which required the Company to make a prompt
offer to repurchase all or any portion of the 10.25% Notes owned by the holders
thereof at 101% of the principal amount, together with accrued interest thereon,
to the date of repurchase. Pursuant to the offer, $99.3 million of 10.25% Notes
were redeemed through August 31, 1994, resulting in a loss on early
extinguishment of debt of $4.1 million. The 10.25% Notes are subordinated to the
Company's Senior Credit Facilities and subsidiary indebtedness.
 
11.375% SENIOR SUBORDINATED NOTES
 
    On August 23, 1994, the Company issued $125 million aggregate principal
amount of 11.375% senior subordinated notes due August 15, 2004 (the "11.375%
Notes"). The 11.375% Notes are subordinated to the Company's Senior Credit
Facilities and subsidiary indebtedness but rank pari passu in right of payment
to the Company's 12.25% Notes and 10.25% Notes. Interest on the 11.375% Notes is
payable semiannually on February 15 and August 15 of each year. The 11.375%
Notes may be redeemed in whole or in part at the option of the Company on or
after August 15, 1999 through August 15, 2002, at specified redemption

    In connection with the Summit merger (see Note 2), the Company acquired a
38.6% interest in Summit Care Corporation ("Summit Care") which operates nursing
care and retirement centers. At August 31, 1994, approximately $37.4 million
aggregate principal amount of the Company's 7.5% Exchangeable Subordinated Notes
due 2003 (the "7.5% Notes"), which were exchangeable, at the option of the
holders, into the Company's 38.6% interest in the Summit Care Common Stock, were
outstanding. The investment in Summit Care was increased approximately $30.5
million in the Summit merger purchase price allocation to estimated fair value
of $37.4 million which was the carrying value of the 7.5% Notes at the merger
date. The 7.5% Notes, as well as accrued interest on the 7.5% Notes, and the
investment in Summit Care common stock were accounted for as an asset held for
sale and the net investment was included in other assets.
 
    From September 1, 1994 through July 31, 1995, $9.6 million of the 7.5% Notes
were voluntarily exchanged for Summit Care common stock. Effective June 1, 1995,
with the consent of the holders of the 7.5% Notes, the Indenture in respect of
the 7.5% Notes was amended to change the earliest redemption date of the 7.5%
Notes from April 1, 1996 to June 1, 1995. The Company issued a redemption notice
for 100% of the outstanding 7.5% Notes on August 3, 1995, and the holders of
$27.8 million of the 7.5% Notes exchanged for Summit Care common stock prior to
the August 28, 1995, redemption date for the balance of the 7.5% Notes. As a
result, as of August 31, 1996, the Company owned 1,414 shares, .02% of the
common stock of Summit Care.
 
NOTE 6--LEASES

COMMON STOCK
 
    The Company has not paid any dividends on its common stock. Under the terms
of the Company's Restated Credit Facility, the Company may not pay dividends on
its common stock.
 
    On November 6, 1995, the Company completed the sale of 10,000,000 shares of
its common stock at a $17.625 per share public offering price. On November 9,
1995, the underwriters exercised an option to purchase an additional 1,500,000
shares to cover over-allotments. The net proceeds of approximately $192.7
million, after deducting offering expenses and underwriting discounts, were used
to reduce all of the indebtedness under the revolving portion of the Restated
Credit Facility in the amount of $27.2 million. The remaining proceeds were used
for general corporate purposes.

WARRANTS
 
    At August 31, 1996, there were warrants outstanding to purchase 92,600
shares of common stock at an exercise price of $17.89 per share. Warrants can be
exercised through April 30, 2000.
 
STOCK OPTIONS AND STOCK BONUS PLANS
 
    On April 19, 1994, OrNda's shareholders approved the 1994 Management Equity
Plan to replace the 1992 Management Equity Plan. No awards were granted under
the 1992 Management Equity Plan. The 1994 Management Equity Plan provides for
the granting of stock options (either incentive or nonqualified), stock
appreciation rights, or limited stock appreciation rights to key employees and
consultants of the Company. Under the 1994 Management Equity Plan, the Company
may grant awards for up to 6,550,000 shares of common stock. Generally, the 1994
Management Equity Plan provides that options may be outstanding for a period of
up to ten years from the date of the grant and may become exercisable at such
time or under such conditions as the compensation committee of the Company's
Board of Directors shall determine. For incentive stock options granted, the
exercise price generally will equal the fair market value of the Company's
common stock on the date of the grant.
 
    Effective November 29, 1995, OrNda's shareholders approved the Outside
Directors Stock Option Plan, under which the Company may grant options to
outside directors for up to 300,000 shares of common stock.
 
    On April 19, 1994, the Company's shareholders approved the Incentive Stock
Bonus Plan which provides for the payment of cash and issuance of shares of the
Company's common stock to key employees as an annual incentive bonus based upon
the extent to which the Company achieves certain performance goals specified in
advance by the compensation committee of the Company's Board of Directors. Under
the Incentive Stock Bonus Plan, the Company may issue up to 600,000 shares of
the Company's common stock. As of August 31, 1996, no options have been granted
under this plan.
 
    In addition to the 7,450,000 shares of common stock reserved for issuance
under the 1994 Management Equity Plan, the Outside Directors Stock Option Plan
and the Incentive Stock Bonus Plan, the Company has reserved 1,434,958 shares of
common stock at August 31, 1996, for issuance pursuant to options granted under
various stock option plans for OrNda, AHM and Summit prior to the AHM Merger and
the Summit merger. No options are available for future grant under the stock
option plans established prior to the April 19, 1994 mergers. On December 31,
1993, OrNda granted options to purchase 500,000 shares of common stock to key
employees at exercise prices ranging from $7.75 to $10.75 per share. Since the
exercise price was below the market value of the Company's common stock on the
date of grant, the Company recorded $2,530,000 of noncash stock option
compensation in fiscal 1994 with an offsetting increase to Additional Paid-In
Capital for the excess of the market price at the date of grant over the
exercise price.

January 1, 1995, through December 31, 1995, the 401(k) Plan was amended to allow
eligible employees to make contributions of 2% to 15% of their annual
compensation and employer contributions were made at a rate of 50% of the
employee contributions up to a maximum of 1.5% of annual compensation. Effective
January 1, 1996, the 401(k) Plan was amended such that employer contributions
are now made in the Company's common stock at a rate of 50% of the employee
contributions up to a maximum of 2.0% of annual compensation. Employer
contributions vest 20% after three years of service and continue vesting at 20%
per year until fully vested. The Company's matching expense for fiscal years
1994, 1995, and 1996 was approximately $3.2 million, $4.5 million, and $4.8
million, respectively.
 
    The carrying amounts and fair values of certain financial instruments,

NOTE 9--COMMITMENTS AND CONTINGENCIES
 
    The Company continually evaluates contingencies based upon the best
available information. Final determination of amounts earned from certain
third-party payors is subject to review by appropriate governmental authorities
or their agents. In the opinion of management, adequate provision has been made
for any adjustments that may result from such reviews.
 
    Broad provisions in the Medicare and Medicaid laws deal with fraud and
abuse, false claims and physician self-referrals as well as similar provisions
in many state laws. In recent years, government investigations of alleged
violations of these laws have become common place in the health care industry.
The Company is currently under civil investigation under the direction of the
Civil Division of the Department of Justice concerning possible violations of
Medicare rules and regulations. The investigation is primarily related to
arrangements between physicians and the twelve hospitals which the Company
acquired from Summit Health, Ltd. in 1994. The Company is fully cooperating with
the government investigation and is voluntarily producing documents related to
the investigation. Also, in an apparently unrelated matter, the government has
requested and the Company has agreed to provide similar records from a single
hospital outside the group acquired from Summit Health, Ltd. in 1994. Although

NOTE 9--COMMITMENTS AND CONTINGENCIES (CONTINUED)
proceedings have been instituted, in the event that the Office of the Inspector
General of the United States Department of Health and Human Services believes
that any wrongdoing has occurred, civil and possibly criminal proceedings could
be instituted. If any such proceedings were instituted and the outcome were
unfavorable, the Company could be subject to fines, penalties and damages
("Monetary Payments") and also could be excluded from Medicare and other
government reimbursement programs. The aggregate amount of the Monetary Payments
and any such exclusion could have a material adverse effect on the Company's
financial position or results of operations. The result of this investigation
and its impact, if any, cannot be predicted or estimated at this time. Based on
information currently available to it, management believes that if the
investigation remains limited to relationships with physicians, remains civil in
nature and, with the single exception noted above, relates to the practices of
the hospitals of an acquired corporation, the final outcome of this
investigation will not have a material adverse effect on the Company's financial
position or results of operations.
 
    The Company is subject to various legal proceedings and claims which arise
in the ordinary course of business. In the opinion of management, the ultimate
resolution of such pending legal proceedings will not have a material effect on
the Company's financial position or results of operations.
 
NOTE 10--SUBSEQUENT EVENTS
 
    Effective September 1, 1996, the Company completed the acquisition of The
Fallon Healthcare System's Saint Vincent Healthcare System, located in
Worcester, Massachusetts, consisting of a 432-bed acute care teaching hospital,
three skilled nursing facilities and other health related companies, and a
minority interest in the 280-member multi-specialty group physician practice,
The Fallon Clinic. The Company has committed to fund the construction, estimated
at $225.0 million, of a new replacement hospital, known as Medical City.
 
    On October 8, 1996, the Company entered into a definitive agreement with
United Western Medical Centers, a not-for-profit corporation headquartered in
Santa Ana, California, to acquire substantially all of United's assets which
consist primarily of Western Medical Center, a 288-bed acute care hospital in
Santa Ana, California; Western Medical Center-Anaheim, a 193-bed acute care
hospital in Anaheim, California; and Western Medical Center-Bartlett, a 202-bed
skilled nursing facility in Santa Ana, California. United Western Medical
Centers has approximately $185 million in annual net revenues in its most recent
fiscal year. The closing of this transaction is subject to customary closing
conditions, Board of Directors' approvals and review by the California Attorney
General.
 
    On October 16, 1996, the Company entered into a definitive agreement to
merge with Tenet Healthcare Corporation ("Tenet"). Under the terms of the
definitive agreement, which was unanimously approved by the Board of Directors
of both companies, shareholders of OrNda common stock would receive 1.35 shares
of Tenet common stock and the associated preferred stock purchase rights for
each share of OrNda common stock. The merger transaction will be tax-free and
accounted for as a pooling of interests and is expected to close in March 1997.
Consummation of the merger is subject to a number of conditions, including
shareholder approval of both companies. The merger is also subject to the
applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements
Act, local regulatory approvals, and confirmation that the transaction qualifies
as a pooling-of-interests for accounting purposes and as a tax-free
reorganization under the Internal Revenue Code.
 
    As of November 13, 1996, the Company is in discussion with its current
syndicate of banks to increase its credit facility to $1.2 billion, an amount
sufficient to cover the Company's pending acquisitions.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Section 78.751 of the Nevada General Corporation Law ("Nevada Law") provides
generally and in pertinent part that a Nevada corporation may indemnify its
directors and officers against expenses, judgments, fines, and settlements
actually and reasonably incurred by them in connection with any civil suit or
action, except actions by or in the right of the corporation, or any
administrative or investigative proceeding if, in connection with the matters in
issue, they acted in good faith and in a manner they reasonably believed to be
in, or not opposed to, the best interests of the corporation, and in connection
with any criminal suit or proceeding, if in connection with the matters in
issue, they had no reasonable cause to believe their conduct was unlawful.
Section 78.751 further provides that, in connection with the defense or
settlement of any action by or in the right of the corporation, a Nevada
corporation may indemnify its directors and officers against expenses actually
and reasonably incurred by them if, in connection with the matters in issue,
they acted in good faith, in a manner they reasonably believed to be in, or not
opposed to, the best interest of the corporation. Section 78.751 further permits
a Nevada corporation to grant its directors and officers additional rights of
indemnification through by-law provisions and otherwise.
 
    Article IX of the Restated By-Laws, as amended, of the Registrant provide
that the Registrant shall indemnify its directors and officers to the fullest
extent permitted by Nevada Law. The Registrant has entered into indemnification
agreements with each of its directors and executive officers. Such
indemnification agreements are intended to provide a contractual right to
indemnification, to the maximum extent permitted by law, for expenses (including
attorneys' fees), judgments, penalties, fines, and amounts paid in settlement
actually and reasonably incurred by the person to be indemnified in connection
with any proceeding (including, to the extent permitted by applicable law, any
derivative action) to which they are, or are threatened to be made, a party by
reason of their status in such positions. Such indemnification agreements do not
change the basic legal standards for indemnification set forth under Nevada Law
or the Restated Articles of Incorporation, as amended, of the Registrant. Such
agreements are intended to be in furtherance, and not in limitation of, the
general right to indemnification provided in the Registrant's Restated Articles
of Incorporation, as amended.
 
    Section 78.037 of the Nevada Law provides that the articles of incorporation
may contain a provision eliminating or limiting the personal liability of a
director or officer to the corporation or its shareholders for monetary damages
for breach of fiduciary duty as a director provided that such provision shall
not
 
                                      II-1
<PAGE>
eliminate or limit the liability of a director or officer (i) for acts or
omissions which involve intentional misconduct or a knowing violation of law, or
(ii) under Section 78.300 of the Nevada Law (relating to liability for
unauthorized acquisitions or redemptions of, or dividends on, capital stock).
Article X of the Restated Articles of Incorporation contains a provision
eliminating the liability of directors and officers to the extent permitted
under Section 78.037 of Nevada law.
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling the Registrant
pursuant to the foregoing provisions, the Registrant has been informed that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act and is therefore
unenforceable.

ITEM 17.  UNDERTAKINGS.
 
    (a) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the Registration Statement shall be
deemed to be a new registration statement relating to the securities offered
herein, and the offering of such securities at that time shall be deemed to be
the initial BONA FIDE offering thereof.
 
    (b) The undersigned Registrant hereby undertakes to deliver or cause to be
delivered with the Prospectus, to each person to whom the Prospectus is sent or
given, the latest annual report, to security holders that is incorporated by
reference in the Prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X is not set forth in the Prospectus, to deliver, or
cause to be delivered to each person to whom the Prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the Prospectus to provide such interim financial information.
 
    (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, the Nevada Law, the
Restated Articles of Incorporation, and the Restated Bylaws, as amended, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

    (d) The Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of Prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in the form of
Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities Act of
1933, each post-effective amendment that contains a form of prospectus shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial BONA FIDE offering thereof.
