                       TENET TO MERGE WITH ORNDA IN TRANSACTION
                                VALUED AT $3.1 BILLION

              Combination Creates Company with $8.5 Billion in Revenues

    NEW YORK, N.Y. - OCTOBER 17, 1996  - Tenet Healthcare Corporation and OrNda
HealthCorp today jointly announced the signing of a definitive merger agreement
under which Tenet will acquire OrNda.  The transaction values OrNda at more than
$3.1 billion.  The resulting company will have pro forma revenues of
approximately $8.5 billion and operate 126 acute care hospitals in 22 states,
principally through the Sunbelt.

    Under terms of the agreement, which was approved yesterday by the boards of
both companies, OrNda shareholders will receive 1.35 shares of Tenet common
stock for each share of OrNda stock in a tax-free exchange.  Based on
approximately 60 million fully diluted OrNda shares and yesterday's closing
price of $22.1/8 per Tenet share.  OrNda shareholders would receive $1.8 billion
in Tenet stock.

    The pooling of interests transaction will create a consolidated company
with pro forma

                                        -more-



earnings before interest, taxes, depreciation and amortization (EBITDA) of
approximately $1.5 billion.  The transaction will be accretive to earnings per
share.

    "Joining these dynamic companies continues the momentum begun with the
creation of Tenet," said Jeffrey C. Barbakow, Tenet chairman and chief executive
officer.  "Less than two years ago, we created a new force in healthcare with
the formation of Tenet.  At that time, we committed ourselves to the delivery of
quality, community-based healthcare, unquestionable business integrity and the
enhancement of shareholder value.  This combination with OrNda will further
these goals.

    "The strategic and geographic match are perfect," Barbakow continued.
"Thirty-two of OrNda's 50 hospitals are a solid fit with existing Tenet
networks.  Also, OrNda meshes very well with us culturally.  During recent
months we have come to know OrNda well and we've been impressed with their
hospitals and their corporate and operating management.  Their facilities and
their pool of talent will be of great benefit to Tenet.  Together, we believe we
will be particularly attractive to other hospitals and health systems seeking
partners to enhance their strategic futures."

    The combination of the two companies is expected to result in approximately
$70 million in annual cost savings, interest reductions and operating synergies
following the first full fiscal year of combined operations.

    Barbakow, 52, will continue as chairman and chief executive officer of the
combined company and Michael H. Focht Sr., 54, will continue as president and
chief operating officer.  Charles N. Martin Jr., 53, OrNda's chairman, president
and chief executive officer, will become Tenet's vice chairman and will be a
member of the executive committee of the company's board

                                        -more-



of directors.  He will also serve as a member of the company's management
committee.

    Tenet's board of directors will be expanded from 11 members to 14 to
welcome Martin and two OrNda board members, Paul S. Levy and Peter A. Joseph,
partners in the merchant banking firm of Joseph, Littlejohn & Levy, an affiliate
of which is OrNda's largest shareholder.

    "Five years ago, OrNda was a collection of 11 hospitals with less than $500
million in revenue," said Martin.  "Today, we have 50 hospitals with pro forma
revenues of approximately $2.7 billion.  Just this year we have substantially
transformed this company in terms of the size and quality of our operations.
This merger creates a large, strong competitor with tremendous momentum and no
constraints on its ability to grow."

    The acquisition will enhance Tenet's competitive presence in Southern
California, South Florida, Dallas and Houston.  In addition, it will give the
company entry into other attractive regions such as the Northwest, New England,
Arizona and Nevada.

    In sprawling Southern California, the transaction more than doubles Tenet's
holdings from 13 hospitals to 29.  Pending transactions previously announced by
OrNda would increase the count to 31.

    "We will be the largest integrated provider system in Southern California
and the only one with a full geographical representation," said Barbakow.  "This
will allow us to work with payors of all types - both private and governmental -
across all of Southern California for the delivery of efficient healthcare
services."

    In South Florida, the transaction further enhances Tenet's strong
integrated delivery system by increasing its acute care hospitals from seven to
11 and expanding the network's geographic reach south to Miami and into Coral
Gables.  Tenet's pending transaction previously

                                        -more-



announced would increase the number of hospitals to 12.

    Key OrNda shareholders representing approximately 14 percent of OrNda's
shares outstanding have agreed to vote in favor of the transaction.

    The companies hope to close the transaction in early March 1997.  It is
subject to approval of shareholders of both companies, review under the Hart-
Scott-Rodino Antitrust Improvements Act and other customary regulatory
approvals.

    Under the terms of the agreement, Tenet or OrNda is each entitled, under
certain circumstances, to receive a termination fee of $50 million from the
other in the event the merger is not completed.  In addition, Tenet has granted
OrNda an option to purchase approximately 10.5 percent of its common stock and
OrNda has granted Tenet an option to purchase 19.9 percent of its common stock
under certain circumstances.

    Donaldson, Lufkin & Jenrette Securities Corporation is serving as financial
advisor to Tenet.  Merrill Lynch & Co. is serving as financial advisor to OrNda.

    OrNda HealthCorp, based in Nashville, Tenn., is the third largest investor-
owned hospital management company in the United States.  It is a leading
provider of healthcare services, delivering a broad range of inpatient and
outpatient healthcare services principally through the operation of 50 acute
care hospitals located in urban and suburban communities in 15 states.

    Tenet, based in Santa Barbara, Calif., is the second-largest investor-owned
healthcare company in the U.S., generating more than $5.5 billion in annual net
operating revenues.  Through its subsidiaries, Tenet owns and operates 76 acute
care hospitals and related businesses in 13 states.
