THIRD AMENDMENT TO TENET HEALTHCARE CORPORATION
                     SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN

     This Third Amendment to the Tenet Healthcare Corporation Supplemental
Executive Retirement Plan (the "Amendment") is made, entered into and effective
as of January 28, 1997.

                                    RECITALS

     A.   Tenet Healthcare Corporation, a Nevada corporation formerly known as
National Medical Enterprises, Inc. ("Tenet") adopted the Supplemental Executive
Retirement Plan (the "Plan") on November 1, 1984, and amended the Plan on May
21, 1986, April 24, 1994, and July 25, 1994.

     B.   Section 5.4 of the Plan provides that Tenet reserves the right, in its
sole discretion, to amend the Plan.

     C.   Tenet desires to amend the Plan as more particularly described below.

     NOW, THEREFORE, intending to be legally bound, Tenet hereby amends the Plan
as follows:

                                    AMENDMENT

     1.   Section 2.10 of the Plan is hereby amended by deleting such Section in
its entirety and replacing it with the following:

          "2.10  EARNINGS.  "Earnings" means the base salary paid to a
          Participant by Tenet or a Subsidiary, excluding bonuses, car
          and other allowances and other cash and non-cash
          compensation.  However, for all Participants actively at
          work on or after February 1, 1997 as full-time, regular
          employees, "Earnings" means the base salary and annual cash
          bonus paid to a Participant by Tenet or a Subsidiary
          excluding car and other allowances and other cash and non-
          cash compensation."

     2.   Section 2.14 is hereby amended by deleting such Section in its
entirety and replacing it with the following:

          "2.14  EXISTING RETIREMENT BENEFIT PLANS ADJUSTMENT FACTOR.
          "Existing Retirement Benefit Plans Adjustment Factor or
          Factors" means the assumed benefit the Participant would be
          eligible for under Social Security and all retirement plans
          of Tenet and its Subsidiaries whether



          or not he participates in such plans.  This Factor will be used for
          calculating all benefits under the Plan and is a projection of the
          benefits payable under the Social Security regulations in effect June
          1, 1984, and retirement plans of Tenet in effect on June 1, 1984, or
          the participant's Date of Enrollment in the Plan, if later.  Once
          established for a Participant this Factor will not thereafter be
          altered to reflect any reduction in benefits under Social Security.
          This Factor will be adjusted to reflect changes in benefits under
          Tenet retirement plans if a Participant is transferred to different
          retirement plans or the Company contribution to a retirement plan is
          increased or decreased from the percentage used for original
          calculation of the Participant's Factor or the Participant becomes
          eligible for other retirement plans adopted by the Company which would
          provide benefits greater or less than the Plan considered in
          calculating the Participant's original Factor, except that such Factor
          for Participant's who are regular, full-time employees actively at
          work with the Company on April 1, 1994, with the corporate office or a
          division or Subsidiary that is not announced as a discontinued
          operation shall be revised based upon the Participant's actual base
          salary as of April 1, 1994, but no Factor will be increased as a
          result of revision of the Factor to use the base salary as of April 1,
          1994; provided, however, for a Participant who is a full-time, regular
          employee actively at work on or after February 1, 1997, the Existing
          Retirement Benefit Plans Adjustment Factor shall be applied only to
          the base salary component of Final Average Earnings."

     3.   Section 2.15 of the Plan is hereby amended by deleting such Section in
its entirety and replacing it with the following:

          "2.15  FINAL AVERAGE EARNINGS.  "Final Average Earnings"
          means the lesser of (i) Actual Final Average Earnings, or
          (ii) if the Participant has completed at least sixty (60)
          months of service, Projected Final Average Earnings;
          however, for a Participant who is actively at work as a
          full-time, regular employee on or after February 1, 1997
          "Final Average Earnings" means Actual Final Average
          Earnings."

     4.   Section 3.2(a)(iii) is hereby amended by deleting such Section in its
entirety and replacing it with the following:

          "3.2(a)(iii)  To arrive at the payments to commence at age
          65 for a Participant whose termination occurs prior to
          February 1, 1997 the amount calculated under paragraphs a(i)
          and a(ii) of this Section 3.2 will be reduced by 0.42% for
          each month Early Retirement commences before age 62.  To
          arrive at the payments to commence

          this Section 3.2 will be reduced by 0.25% for each month
          Early Retirement commences before age 62."

     5.   Section 3.2(b) is hereby amended by deleting such Section in its
entirety and replacing it with the following:

          "3.2(b)  Upon the written request of a Participant prior to
          termination of employment, the Committee, in its sole and
          absolute discretion, may authorize payment of the Early
          Retirement Benefit at a date prior to the Participant's
          attainment of age 65; provided, however, that in such event
          the amount calculated under paragraphs a(i) and a(iii) of
          this Section 3.2 shall be further reduced by 0.42% for each
          month that the  date of the commencement of payment precedes
          the date on which the Participant will attain age 62;
          however, for a Participant who is actively at work as a
          full-time, regular employee on or after February 1, 1997,
          the amount of further reduction under paragraphs a(i) and
          a(iii) of this Section 3.2 shall be 0.25% for each month
          that the date of commencement of payment precedes the date
          on which the Participant will attain age 62."

     6.   Section 3.4(c)(iii) is hereby amended by deleting such Section in its
entirety and replacing it with the following:

          "3.4(c)(iii)  If a Participant, who has a vested interest
          under Section 3.3, dies while still actively employed by
          Tenet or a Subsidiary or on Disability before he was
          eligible for Early Retirement, his Surviving Spouse or
          Eligible Children shall be entitled at the Participant's
          death to receive 50% of the Retirement Benefit (in
          accordance with Sections 3.5 and 3.6) calculated as if the
          Participant was age 55 and eligible for Early Retirement on
          the day before the Participant's death; provided, however,
          that the combined reductions for Early Retirement and early
          payment shall not exceed 21% of the amount calculated under
          paragraphs a(i) and a(ii) of Section 3.2."

          percentage reduction for Early Retirement at age 55 (i.e.,
          21%)."



     8.   Section 3.8(b) is hereby amended by deleting such Section in its

          yet begun to receive benefit payments under the Plan and
          whose employment is Terminated without cause or who
          voluntarily Terminates Employment following (a) a material
          downward change in the functions, duties, or
          responsibilities which reduce the rank or position of the
          Participant, (b) (i) a reduction in the Participant's annual
          base salary, or (ii) a material reduction in the

          transfer of a Participant's office to a location that is
          more than fifty (50) miles from the Participant's current
          principal office location, if such Termination of Employment
          occurs within two years following a Change of Control of
          Tenet while this Plan remains in effect, the provisions of
          Section 3.8(a) above shall not apply and (i) a Participant's
          Early or Normal Retirement Benefits under this Plan (a) will

          a Participant by Tenet or a Subsidiary, excluding (A) any
          cash bonus paid under the LTIP, (B) any car and other
          allowances and (C) other cash and non-cash compensation",
          and (iii) notwithstanding any other provision of this Plan
          to the contrary, a Participant will be entitled to receive
          the Normal Retirement Benefit on or after the age of 60,
          without reduction, and after the age of 55 with a reduction
          of 0.25% per month for each month for which the benefit
          commences to be paid prior to the Participant's attaining
