                           EMPLOYEE LEASING AGREEMENT

     THIS EMPLOYEE LEASING AGREEMENT (the "Agreement") is entered into
effective as of October 15, 1999, by and between Iasis Healthcare Corporation,
a Delaware corporation, as successor-in-interest to JLL Hospital, LLC, a
Delaware limited liability company (the "Lessee") and Tenet Healthcare
Corporation, a Nevada corporation (the "Lessor"); provided, however that OrNda
HealthCorp. of Phoenix, Inc., American Medical (Central), Inc. S.C. San
Antonio, Inc., Mesa General Hospital Medical Center, Inc., Tenet Texas
Employment, Inc., National Medical Services, Inc. and Tenet HealthSystem
Medical, Inc. shall each be a party to this Agreement and a Lessor to the
extent each employs individuals at any of the Facilities.

     WHEREAS, the Lessor has agreed to sell to the Lessee, and the Lessee has
agreed to purchase from the Lessor, certain healthcare assets and businesses of
the Lessor and its affiliates (the "Facilities") upon the terms and conditions
set forth in the Asset Sale Agreement by and between Lessee and Lessor dated as
of August 15, 1999 and the Asset Sale Agreement between Odessa Hospital, Ltd.
and Lessee dated August 15, 1999 (collectively, "Asset Sale Agreements"); and

     WHEREAS, the Lessee desires to retain, and the Lessor desires to provide,
the temporary services of the Lessor's work force at the Facilities (the
"Facility Employees") in order to continue without interruption the operation
of the transferred assets and business following sale of the same by the Lessor
to the Lessee, until such time as the Facility Employees shall become employed
by Lessee.

     NOW THEREFORE, in consideration of the premises and the representations,
warranties, covenants, agreements and undertakings hereinafter made, the
parties hereby agree as follows:

     1. Term. The term of this Agreement shall be from the "Closing Date," as
such term is defined in the Asset Sale Agreements, through December 31, 1999.

     2. Staffing. Lessor agrees to continue to employ the Facility Employees,
and to make the services of such employees available to Lessee, for the term of
this Agreement. Subject to Sections 3, 5 and 7 hereof, Lessor will continue to
be responsible for all wages, salaries and other compensation, employee
benefits, insurance, workers' compensation, employment taxes, withholding,
employee-related reporting, filing, and disclosure obligations, compliance with
all employment laws, and all other employment-related liabilities for the
Facility Employees which arise during the term of this Agreement.

     3. Compensation. In exchange for Lessor's provision of staffing services,
Lessee shall pay as described below an amount equal to the out-of-pocket costs
or expenses (including but not limited to wages, salaries and other
compensation, employee benefits, insurance, workers' compensation, employment
taxes, withholding, administration, and insurance costs) incurred by Lessor in
connection with continued employment of its employees for the term of this
Agreement. Lessor shall provide the amount of such out-of -pocket costs or
expenses to Lessee by 5:00 p.m. Eastern Time on the Wednesday immediately
preceding the payday for the Facility Employees and Lessee shall wire said
amount on the following day, Thursday, so as to

<PAGE>   2

ensure that Lessor receives said amount no later than 5:00 p.m. Eastern Time
the following day, Thursday, in Lessor's account as designated by Lessor from
time to time.

     4. Supervision. During the term of this Agreement, Lessor agrees that the
Facility Employees will perform such services as may be mutually agreed upon by
Lessor and Lessee. Lessee shall not act as an employer with respect to the
Facility Employees and shall have no responsibility, authority, or liability as
such. Lessor reserves the right and authority, in its capacity as employer, to
direct, supervise, and discipline (including hire, retain, and terminate) the
Facility Employees. However, Lessee shall be permitted to reasonably request
that Lessor release or replace any Facility Employee, which request shall be
promptly considered by Lessor. In particular, Lessee shall have the authority
to designate tasks to be performed, and shall have the authority to instruct
and oversee employees in the manner, means and method of accomplishing such
tasks.

     5. Compliance. To the extent that Lessor is responsible for any legal
liability relating to or arising out of events, occurrences, conditions,
actions, or inactions with respect to the Facility Employees during the term of
this Agreement, including, without limitation, claims of, for, or relating to
employment discrimination, unfair labor practices, wage and hour violations,
health and safety violations, workers' compensation, employee benefits,
wrongful discharge, tort liability, breach of agreement, or any other violation
of sate or federal law or regulation, Lessee agrees to defend, indemnify, and
hold harmless Lessor from and against any and all such liabilities; provided,
however, that Lessee shall not be required to indemnify Lessor from any
liability resulting from Lessor's gross negligence or willful misconduct.

     6. Wages and Salaries. Lessor shall pay the Facility Employees such wages,
salaries and bonuses, at such rate and at such times as it shall determine from
time to time for each Facility Employee, consistent with past employment
practices as of the effective date of this Agreement. Subject to Section 3
hereof, all withholding and payroll taxes due with respect to such payments, as
well as any other legally required contributions (such as in the nature of
social security payments) shall be the sole responsibility of Lessor. Lessee
shall not be obligated to pay any wage or salary to the Facility Employees
directly, nor shall it be responsible for any withholding taxes or
contributions due with respect to such payments.

     7.   Employee Benefits.

          (a) During the term of this Agreement, Lessor shall continue to
     maintain its employee benefit and fringe benefit plans, programs and
     arrangements in effect at the execution of this Agreement and continue to
     provide its employees with such employee benefits and fringe benefits as
     authorized and provided pursuant to those plans, programs and arrangements
     as of such date, or as thereafter amended, and Lessee shall fully
     reimburse Lessor for all benefit costs, including without limitation claim
     costs, premium costs and costs of administration paid by Lessor with
     respect to all such benefits including, without limitation, the ongoing
     costs associated with offering COBRA coverage to any Facility Employees
     (or dependent thereof) who terminates employment with Lessor (or otherwise
     incurs a qualified event) during the term of this Agreement (collectively,
     the "Benefit Costs"). Lessor shall provide the amount of the Benefit Costs
     to Lessee for a particular calendar month by 5:00 p.m. Eastern Time on the
     day which is

<PAGE>   3

     two (2) calendar days prior to the last calendar day of such month (the
     "Submittal Date"), and Lessee shall wire said amount on the following
     calendar day (the "Pay Date"), so as to ensure that Lessor receives said
     amount no later than 5:00 p.m. Eastern Time on the Pay Date, in Lessor's
     account as designated from time to time. Notwithstanding the foregoing, if
     either the Submittal Date or the Pay Date falls on a day which is not a
     business day, the Submittal Date and the Pay Date shall be accelerated in
     such calendar month to the first date in such calendar month which would
     enable both the Submittal Date and the Pay Date to fall on a business day.
     Lessor shall give Lessee 30 days advance notice of any plan amendment that
     would increase the employer costs thereunder.

          (b) Lessor agrees to purchase and maintain from vendors recommended
     and secured by Lessee, at Lessee's expense, such stop loss insurance as
     may be requested and secured by Lessee with respect to the medical and
     dental benefits provided to the Facility Employees.

     8. Personnel Policies. Except as specified herein, all terms and
conditions of employment applicable to the Facility Employees shall be governed
by Lessor's personnel policies and practices in effect at the execution of this
Agreement, or as amended from time to time, and Lessee shall have no authority
to enforce, alter or interpret such policies and practices.

     9. Workers' Compensation. Lessor shall provide workers' compensation
insurance for Lessor's employees during the term of the Agreement, provided,
however, that Lessee shall fully reimburse Lessor for any and all claims,
premiums and administrative costs associated with such coverage.

     10. Transfer. Upon termination of this Agreement, Lessee shall
unconditionally make offers of employment to all Facility Employees who are
leased to Lessee under this Agreement at the expiration of the term hereof in
accordance with section 5.3 of the Asset Sale Agreements.

     11. Third Party Beneficiaries. This Agreement and all conditions and
provisions hereof are for the sole and exclusive benefit of the parties hereto
and their respective successors and assigns and are not intended for the
benefit of any other person. In particular, nothing expressed by or mentioned
in this Agreement is intended or shall be construed to give any Facility
Employee or his or her respective heirs, assigns and beneficiaries, any legal
or equitable right, remedy or claim under or in respect to this Agreement or
any provision herein contained.

     12. Notices. Any notice or other communication required or which may be
given hereunder shall be in writing and either be (i) delivered personally,
(ii) deposited in the United States mail, first class, certified, return
receipt requested, postage prepaid, or (iii) sent by electronic transmission,

                                 TENET BUYPOWER
                         PURCHASING ASSISTANCE AGREEMENT

This Purchasing Assistance Agreement (this "Agreement") is entered into by and
between Iasis Healthcare Corporation, a Delaware corporation as successor in
interest to JLL Hospital, LLC, a Delaware limited liability company, for itself
and on behalf of its subsidiaries identified on Exhibit A, attached hereto and
incorporated herein by this reference (collectively hereinafter, "Purchaser"),
located at 104 Woodmont, Suite 101, Nashville, Tennessee 37205, and Tenet
HealthSystem Medical, Inc., on behalf of itself and its affiliates, a Delaware
Corporation ("Tenet"), located at 14001 Dallas Parkway, Dallas, Texas 75240.

                                   WITNESSETH:

A.       Purchaser (through its direct and indirect subsidiaries) owns and/or
         operates those certain facilities listed on Exhibit B, attached hereto
         and incorporated herein by this reference (hereinafter referred to as
         "a facility" or collectively as "the facilities"), through which
         Purchaser and its direct and indirect subsidiaries (collectively,
         "Hospital") provides medical and hospital services.

B.       Tenet maintains agreements for purchasing various goods, supplies,
         materials, dietary products, pharmaceutical and equipment used by
         hospitals on a national basis.

C.       Hospital desires to purchase such goods, supplies, materials, dietary
         products, pharmaceutical and equipment under said national supply and
         purchase agreements to the extent permitted by such agreements, and to
         the extent that the price for purchase hereunder would be based upon
         meeting vendor terms and conditions.

NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth, it is agreed as follows:

1.       PURPOSE:

         Hospital hereby employs Tenet to assist Hospital in the purchasing of
         various supplies, goods, materials, dietary products, pharmaceutical
         and equipment used in the Hospital's normal and customary operations of
         the facilities and Tenet agrees to assist Hospital in the purchasing of
         such supplies, goods, materials, dietary products, pharmaceutical and
         equipment for the facilities, all as is more fully set forth below.

2.       TERM:

         Subject to prior termination under Paragraph 6, below, the term of this
         Agreement shall be for a period of one year commencing on October 5,
         1999, and ending on October 16, 2000 (the "Initial Term"); provided,
         however, that unless notice of termination is provided by Hospital at
         least 30 days prior to the expiration of the Initial Term or any
         renewal term, this agreement shall automatically be extended for
         successive one year periods.

<PAGE>   2

3.       TENET'S RESPONSIBILITIES:

         a.       Prior to the commencement date of this Agreement, Tenet has
                  delivered, or caused to be delivered, to Hospital a copy (or
                  brief summary hereof) of all national purchase and supply
                  agreements which Tenet has in effect at that time.
                  Additionally, Tenet will, during the term hereof, provide
                  Hospital with copies of any additional amendments, changes, or
                  terminations to such agreements on a timely basis so that
                  Hospital can be advised thereof.

         b.       Tenet will provide consultation with Hospital to effect a
                  smooth transition.

         c.       Tenet shall notify each of the contracting parties to such
                  national purchase and supply agreements that Hospital is
                  participating in such agreements to the extent permitted by
                  such agreements and accordingly is entitled to purchase of
                  such goods, supplies, materials, dietary products,
                  pharmaceutical and equipment and receive the same discounts
                  thereunder as Tenet.

         d.       Hospital acknowledges that Tenet has certain subsidiaries and
                  divisions in the health care field. Certain of these
                  subsidiaries or divisions may, from time to time, make
                  proposals to or do business with Hospital. Tenet shall in each
                  instance cause the disclosure of the related nature of such
                  enterprises, and Hospital shall in each such instance be free
                  to enter into or reject any such proposals or business dealing
                  solely on the respective merits.

4.       REPRESENTATIONS AND COVENANTS OF HOSPITAL:

         Hospital hereby represents to and covenants with Tenet as follows:

         a.       All purchasing by Hospital of goods, supplies, materials,
                  dietary products, pharmaceuticals and equipment under said
                  national purchasing and supply agreements shall be in the name
                  of Hospital or its controlled affiliates, and Hospital shall
                  be solely responsible for payment therefor.

         b.       Any purchase by Hospital under any such national purchase and
                  supply agreement will be between Hospital and the respective
                  contractor; Tenet does not make any warranty, express or
                  implied, as to such goods, supplies, materials, dietary
                  products, pharmaceuticals or equipment.

         c.       Hospital shall indemnify and hold Tenet harmless from any
                  liability brought against them or any of them as a result of
                  Hospital's action or inaction with respect to such national
                  purchase and supply agreements.

5.       ADMINISTRATIVE FEES:

         Tenet shall share back 50% of all administrative fees paid by suppliers
         against the Hospital's purchases as identified in Paragraph 8 of this
         Agreement.

6.       TERMINATION:

         a.       During the term hereof, either party may terminate this
                  Agreement with or without

<PAGE>   3

                  cause at any time by giving written notice to the other, such
                  termination to be effective sixty (60) days after the date
                  such notice is given.

         b.       Upon termination of this Agreement, whether by expiration of
                  its term or otherwise, provided that Tenet is not performing
                  services on a month-to-month basis as provided in Paragraph 2
                  above, neither Hospital nor Tenet shall have any further
                  obligations hereunder, and particularly no obligation to
                  maintain, update, or advise concerning any system or procedure
                  provided hereunder.

7.       SUCCESSORS AND ASSIGNS:

         a.       No party hereto may assign its interest in or delegate the
                  performance of its obligations under this Agreement to any
                  other person without obtaining the prior written consent of
                  the other party. Hospital may assign its interest to a duly
                  authorized successor in interest provided, however, that any
                  such transferee or assignee shall expressly assume in writing
                  the obligations of Hospital to Tenet as set forth herein.

         b.       The terms, provisions, covenants, obligations and conditions
                  of this Agreement shall be binding upon and shall inure to the
                  benefit of the successors in interest and the assigns of the
                  parties hereto, provided that no assignment, transfer, pledge
                  or mortgage by or through either party, as the case may be, in
                  violation of the provisions of this Agreement, shall vest any
                  rights in the assignee, transferee, pledgee or mortgagee.

8.       FEE FOR PURCHASING ASSISTANCE AGREEMENT:

         Hospital acknowledges that, as part of an agreement to furnish goods or
         services to Hospital, Tenet may receive a group purchasing
         administrative fee in connection with certain products that are
         purchased, licensed or leased by Hospital. Such payment shall equal 3%
         or less of the purchase price of the goods or services provided by the
         participating vendor. Tenet shall disclose to Hospital in writing, on
         an annual basis, and to the Secretary of Health and Human Services upon
         his or her request, the amount received from each vendor with respect
         to purchases made by or on behalf of Hospital. Within 90 days after the
         end of each fiscal quarter of Tenet (FYE May 31) during the term of
         this Agreement, Tenet shall provide Hospital with information from
         venders regarding administrative fees with respect to purchases by
         Hospital hereunder for such quarterly period.

9.       NOTICES:

         Any notice by any party to the other shall be in writing and shall be

         delivered personally or (b) four (4) days after it is deposited in the
         U.S. mail, postage prepaid, certified with return receipt requested and

         this Agreement shall be brought in the courts of the State of New York.

11.      ACCESS TO BOOKS AND RECORDS OF TENET BY SECRETARY OF HHS OR AUTHORIZED
         REPRESENTATIVE:

         Upon written request of the Secretary of Health and Human Services or
         the Comptroller General or any of their duly authorized
         representatives, Tenet or any other related organization providing
         services with a value or cost of ten thousand dollars ($10,000.00) or

         such services. Such inspection shall be available up to four (4) years
         after the rendering of such services. This paragraph is not intended to
         prohibit or impede any state audits pursuant to state law.

12.      ENTIRE AGREEMENT:

         This Agreement constitutes the sole and only Agreement of the parties
         hereto with respect to purchasing assistance services to the facilities
         and correctly sets forth the rights, duties, and obligations of each to
         the other as of its date. Any and all prior agreements, promises,
