                                    RECITALS

      A. Pursuant to the terms of the Amended and Restated Regulations of THVGl
(the "THVGl Regulations") and those certain Transfer Agreements and Consents,
all of which were effective as of February 1, 1999 and have been executed and
delivered by USP, Baylor and certain other parties, USP and Baylor are each
members of and each owns a 50% Ownership Interest (as such term is defined in
the THVGl Regulations) in THVGl.

      B. USP's parent company, United Surgical Partners International, Inc., a
Delaware corporation ("USP Parent"), is a party to that certain Asset Purchase
Agreement, dated as of December 18, 1998, as modified and supplemented by that
certain Option and Amendment Agreement, dated as of December 22, 1998
(collectively, the "HealthFirst Purchase Agreement"), with HealthFirst
Management, L.L.C., a Texas limited liability company ("HealthFirst"), and
certain other parties. The HealthFirst Purchase Agreement is attached hereto as
EXHIBIT A. Prior to the consummation of the transactions provided for in the
HealthFirst purchase Agreement, USP Parent assigned all of its rights and
interests in the HealthFirst Purchase Agreement to USP and, accordingly, upon
the consummation of the transactions provided for therein, USP acquired the
"Transferred Assets" (as such term is defined in the HealthFirst Purchase
Agreement).

      C. Unless otherwise defined in this Agreement, the capitalized terms used
in this Agreement shall have the meanings ascribed to them in the HealthFirst
Purchase Agreement. Any capitalized terms used in this Agreement that are not
defined either in this Agreement or in the HealthFirst Purchase Agreement shall
have the meanings ascribed to them in the THVGl Regulations.

      D. Baylor currently owns and operates, either directly or through a
partnership that is 100% owned by Baylor and its Subsidiaries, both (1) Baylor
Surgicare, located at 3920

                                        1
<PAGE>
Worth Street, Dallas, Texas 75246 ("Baylor Surgicare"), and (2) Texas Surgery
Center, located at 3535 Worth Street, Suite 700, Dallas, Texas 75246 ("Texas
Surgery Center"). Baylor Surgicare and Texas Surgery Center are sometimes
hereinafter collectively referred to as the "Baylor Centers."

      E. Pursuant to the terms of the HealthFirst Purchase Agreement, USP has
acquired (1) a 20% general partner interest in both DeSoto Surgicare Partners,
Ltd., a Texas limited partnership ("DeSoto") , and Metroplex Surgicare Partners,
Ltd., a Texas limited partnership ("Metroplex"), (2) options (the "HealthFirst
Options") to purchase the partnership interests formerly held by HealthFirst in
Irving Surgery Center, Ltd., a Texas limited partnership ("Irving"), Dallas
Surgery Partners, a Texas general partnership ("DSP"), and Forth Worth Surgicare
Partners, Ltd., a Texas limited partnership ("Fort Worth"), and (3) all rights
and interests of HealthFirst and the Management Sellers in and to the respective
HealthFirst Management Agreements with DeSoto, Metroplex, Irving, DSP and Fort
Worth.

      F. The purpose of this Agreement is to set forth the terms and conditions
of the following transactions:

      (1) Baylor will contribute to THVGl all of the assets (other than land and
buildings), subject to certain designated liabilities, of the Baylor Centers in
exchange for an additional Ownership Interest in THVGl. USP shall concurrently
purchase one-half of such additional Ownership Interest from Baylor.

      (2) THVGl has formed a wholly owned limited liability company, known as
Texas Health Venture VII L.L.C. (the "Baylor Center General Partner"), which in
turn has formed Dallas Surgical Partners L.P., a Texas limited partnership (the
"Baylor Limited Partnership"), and THVGl shall contribute to the Baylor Center
General Partner, which in turn shall contribute to the Baylor Limited
Partnership, all of the assets (subject to all assumed liabilities) of the
Baylor Centers acquired by THVGl from Baylor.

      (3) The Baylor Limited Partnership will (a) obtain a loan that is secured
by the assets of the Baylor Centers, which loan shall be in an amount and on
terms approved by the Managers of THVGl, and (b) syndicate to local
physician/investors limited partnership interests in the Baylor Limited
Partnership representing up to a 25% interest in the Baylor Limited Partnership.
The proceeds of said loan and said syndication of limited partnership interests
shall be distributed by the Baylor Limited Partnership to the Baylor Center
General Partner and, in

                                        2
<PAGE>
turn, to THVGl and to Baylor and USP (subject to any retention by THVGl approved
by its members).

      (4) USP and Baylor have organized THVG2 by entering into Regulations (the
"THVG2 Regulations") substantially in the form of Exhibit D attached hereto. USP
shall contribute the Transferred Assets to THVG2 in exchange for a 51% interest
in THVG2 and the cash contribution to be made by Baylor for its 49% interest in
THVG2.

      (5) THVG2, Baylor and USP shall enter into a Management Agreement (the
"THVG2 Management Agreement") substantially in the form of Exhibit D attached to
the THVG2 Regulations, and Baylor shall pay to USP a pro rata share (based on
Baylor's share of the management fees payable to Baylor under the THVG2
Management Agreement) of USP's cost of acquiring the HealthFirst Management
Agreements that are included in the Transferred Assets.

      (6) Baylor Health Care System, a Texas non-profit corporation ("BHCS"),
and Baylor (each as landlord) shall enter into a Lease Agreement with the Baylor
Limited Partnership for the real property used by each of the Baylor Centers
(collectively, the "Baylor Real Property").

      THEREFORE, in consideration of the foregoing premises and the mutual
covenants contained herein, the parties hereto agree as follows:

   1. CONTRIBUTION OF BAYLOR CENTER ASSETS TO THVG1.

      1.1 BAYLOR AGREEMENT TO CONTRIBUTE ASSETS. Subject to the terms and
conditions of this Agreement, at the Closing (as defined below), Baylor shall
contribute to THVG1 all tangible and intangible assets owned by Baylor that are
primarily used in the operations of the business of the Baylor Centers (other
than the Excluded Assets, as defined below), including without limitation cash
in an amount equal to $100,000 (the "Transferred Baylor Center Cash"), all
accounts receivable, prepaid expenses (other than prepaid insurance expenses),
deposits, inventory and supplies, contract rights, other current assets,
licenses (to the extent transferable), computer software, equipment, fixtures,
furniture, surgical instruments (including without limitation the equipment,
fixtures, furniture and instruments described in Schedule 1.1A attached hereto),
books and records (including without limitation computer stored records) and
goodwill (collectively, the "Baylor Center Assets") ; provided, however,

                                        3
<PAGE>
that with respect to such books and records that are integrated with the books
and records of Baylor or its Affiliates and cannot be readily separated for
transfer to THVG1, Baylor shall instead provide THVG1 with access to and the
right to copy (at no expense to THVG1) the portion of such books and records
that are Baylor Center Assets. Notwithstanding the foregoing, the following
assets shall not be part of the Baylor Center Assets (the "Excluded Baylor
Assets"): (a) cash and cash equivalents in excess of the Transferred Baylor
Center Cash; (b) Baylor's rights under this Agreement; (c) all rights under
insurance policies and self-insurance programs; (d) leasehold improvements; (e)
assets that are not owned by Baylor or are not used primarily in the business of
the Baylor Centers; and (f) managed care contracts not listed in SCHEDULE 9.6. A
list of all material items used in the business of the Baylor Centers that are
owned by a Baylor Affiliate (and not Baylor) is set forth in SCHEDULE 1.lB
attached hereto; Baylor will use reasonable efforts to cause its Affiliates to
provide these items to the Baylor Limited Partnership in accordance with past
practices for a fair market use or rental charge so long as they are needed by
the Baylor Limited Partnership and they are available for such use.

      1.2 ISSUANCE OF OWNERSHIP INTEREST; PARTIAL BY USP. In consideration for
Baylor's contribution and transfer of the Baylor Center Assets to THVG1, Baylor
shall be issued a 97% Ownership Interest in THVG1. Immediately after such
issuance, Baylor shall sell to USP, and USP agrees to purchase from Baylor, one
half of such Ownership Interest for the following consideration:

      (a) CLOSING DATE PAYMENT. At the Closing, USP shall pay to Baylor cash in
the aggregate amount of $6,503,080.

      (b) CONTINGENT POST-CLOSING PAYMENTS. In addition to the payments to be
made pursuant to Section 1.2(a) above and as additional consideration for the
sale of such Ownership Interest, USP shall pay to Baylor 50% of the following
additional amounts:

            (i) An amount equal to four times the excess (if any) of (A) the
      aggregate net earnings before interest, taxes, depreciation, amortization
      and management fees earned by the Baylor Limited Partnership (the total of
      which is hereinafter collectively referred to as the "EBITDAM"), for the
      12 month period beginning on the "Effective Date" (as defined in Section 6
      below) (the "First Year") over (B) $1,858,023 (the "Base Amount"); plus

                                        4
<PAGE>
            (ii) Three times the amount by which EBITDAM for the 12 month period
      beginning on the first anniversary of the Effective Date (the "Second
      Year") exceeds the greater of the Base Amount or the EBITDAM for the First
      Year; plus

            (iii) Three times the amount by which EBITDAM for the 12 month
      period beginning on the second anniversary of the Effective Date (the
      "Third Year") exceeds the greatest of (A) the Base Amount, (B) the EBITDAM
      for the First Year or (C) the EBITDAM for the Second Year;

provided, however, that the total amount payable pursuant to this Section 1.2(b)
shall not exceed $2,601,232.

      For purposes of this Section 1.2(b), EBITDAM shall be determined in
accordance with generally accepted accounting principles applied in a manner
consistent with the attached SCHEDULE 1.2 ("GAAP"); provided, however, that (1)
extraordinary items (as determined in accordance with GAAP) shall be excluded,
(2) if the EBITDAM for the First Year or the Second Year is a negative amount,
such negative amount shall carryover and be treated as an expense in the next 12
month period, (3) the calculation shall not include reserves or contingencies
for expenses as to which any party has an indemnification obligation to the
other party under this Agreement and (4) there shall be no charge for
professional services (including without limitation legal expenses) incurred by
any party in connection with this Agreement or the transactions provided for
herein. Baylor and USP each shall have access to all books and records and (at
their expense) the right to review and audit all financial statements relating
to the Baylor Centers and/or the Baylor Limited Partnership.

      The calculation of EBITDAM for each of the First, Second and Third Years
shall initially be made by USP and a statement (the "Statement") reflecting each
such calculation in reasonable detail shall be provided to Baylor within 60 days
after the end of the respective periods for which such calculations are to be
made. If Baylor does not notify USP of any objection to a Statement within 60
days after the receipt of such Statement, the Statement shall be deemed accepted
on behalf of each of the parties hereto. If Baylor provides notice of any
objection to a Statement (which notice shall include a description of such
objections) within such 60 day period, USP and Baylor shall use their
commercially reasonable efforts to resolve any differences relating to the
Statement within 15 days after such objection is delivered to USP. If the
disagreement is

                                        5
<PAGE>
not resolved by that date, however, either Baylor or USP may submit the matter
for a binding determination of the calculation of EBITDAM set forth in the
Statement to THVG1's outside accounting firm or another nationally recognized
accounting firm approved by USP and Baylor, which firm shall act as an expert
and not as an arbitrator in making such determination; the fees of such
accounting firm, which shall be billed separately and independently from any
other services provided by such firm, shall be paid 50% by USP and 50% by
Baylor.

      1.3. ASSUMPTION OF CERTAIN LIABILITIES; EXCLUDED LIABILITIES. THVG1 shall
assume and be responsible for all of the obligations, duties and liabilities
relating to the Baylor Centers (i) that are current trade payables incurred in
the ordinary course of business of the Baylor Centers and are outstanding on the
Effective Date, (ii) that are accrued employee vacation or sick leave benefits
for employees of the Baylor Centers who are hired by USP on or immediately
following the Closing Date or (iii) that arise due to acts or omissions
occurring on or after the Effective Date, including without limitation
obligations under the contracts, leases and other instruments or commitments
that either (A) are described in SCHEDULE 9.6 attached hereto or (B) relate to
the Baylor Centers, do not involve a non-cancellable financial obligation of
more than $25,000 and are cancellable without cost or penalty no later than 12
months after the Closing Date. It is understood and agreed, however, that THVG1
shall not assume, pay or be responsible for any other liability, duty or
obligation of Baylor or any of its Affiliates (except for THVG1 and its
Subsidiaries) arising due to any act or omission occurring prior to the
Effective Date, including without limitation: (a) any trade payable that is more
than 60 days past due; (b) any obligation under any of Baylor's current real
property leases relating to any Baylor Center (which shall be replaced at the
Closing as provided in Section 12.8) or any other outstanding contract, lease,
instrument or commitment not described in clause (iii) (A) or (8) above; (c) any
claim or contingent liability arising from the operations of any Baylor Center
prior to the Effective Date, or based upon any acts or omissions of Baylor or
its Affiliates, employees, agents or independent contractors, or any other event
that has occurred, prior to the Effective Date, including without limitation any
malpractice claim, EEOC claim, workers' compensation claim or other claim by any
present or former employee; (d) liabilities or obligations of Baylor or its
Affiliates arising under the Medicare or Medicaid program or any other third
party payor program; (e) the costs and expenses associated with this Agreement
that, as provided in Section 10.4, are to be borne by Baylor; (f) any obligation
or liability under any employee benefit plan (including without limitation any

                                        6
<PAGE>
bonus, retirement, pension, profit sharing or similar plan) in which any
employee of a Baylor Center participates, other than accrued employee vacation
and sick time as described in subsection (ii) above; (g) any obligation relating
to any professional liability insurance policy, including without limitation
premiums, assessments and charges for underpayments, for any period prior to the
Effective Date; (h) any indebtedness or payment obligation to Baylor or any
Affiliate of Baylor; (i) any federal, state or local income taxes or
liabilities; or (j) any obligation, liability or claim as to which Baylor would
have an indemnity obligation under Section 13.1 hereof (collectively, the
"Excluded Liabilities").

   2. CONTRIBUTION OF USP ASSETS TO THVG2.

      2.1 USP'S .AGREEMENT TO TRANSFER ASSETS. Subject to the terms and
conditions of this Agreement, at the Closing, USP shall transfer to THVG2 the
Transferred Assets (as that term is defined in HealthFirst Purchase Agreement),
all rights and interest of USP in and under the HealthFirst Purchase Agreement
and the HealthFirst Management Agreements, all books and records, computer
hardware and software and other assets of USP or its Affiliates that are
primarily used in the operations of the business of DeSoto or Metroplex or used
primarily in performing the HealthFirst Management Agreements (collectively, the
"USP assets"). Not withstanding the foregoing, the following assets shall not
be part of the USP Assets: (a) USP's share of cash and cash equivalent assets of
DeSoto that are in excess of the $50,000 as of the Effective Date; (b) USP's
share of cash and cash equivalent assets of Metroplex that are in excess of
$50,000 as of the Effective Date; (c) all earned but unpaid management fees
under the HealthFirst Management Agreements as of the effective Date; and (d)
USP's rights under this Agreement.

      2.2 CONSIDERATION. In full consideration for USP's contribution of the USP
Assets to THVG2:

      (a) CLOSING DATE CONSIDERATION. At the Closing, (i) THVG2 shall issue to
USP membership interests in THVG2 representing a 51% ownership interest in THVG2
and (ii) THVG2 shall pay to USP cash in the amount of $1,287,275.

      (b) ASSUMPTION OF FURTHER PAYMENT OBLIGATIONS. In addition, THVG2 hereby
assumes the obligation to make any and all payments that become due to the
Partnership Sellers pursuant to Sections l(c) and 8(e)(iv) of the HealthFirst
Purchase Agreement. To the extent that USP is obligated to deliver shares of the
Class A Common Stock, par value $.01 per share, of USP

                                        7
<PAGE>
Parent (the "USP Common Stock") in connection with any such payment obligation
(as provided in Section l(d). of the HealthFirst Purchase Agreement), USP shall
deliver such USP Common Stock to the parties entitled to receive such shares and
THVG2 shall pay cash to USP equal to the fair market value of such USP Common
Stock, determined in accordance with the provisions of said Section l(d) of the
HealthFirst Purchase Agreement.

      (c) MANAGEMENT AGREEMENTS. Concurrently with USP's contribution of the USP
Assets to THVG2, which assets include the HealthFirst Management Agreements,
THVG2, USP and Baylor shall enter into the THVG2 Management Agreement. Since the
THVG2 Management Agreement provides for the payment of management fees to USP
and Baylor that total 100% of all management fees that THVG2 will earn under the
Management Agreements, the parties hereto agree that, for capital account
purposes, the Management Agreements contributed by USP as part of the USP Assets
shall have a value of zero. Accordingly, the value of the USP Assets to be
credited to USP's capital account in THVG2 shall be $2,627,092 (less the payment
made to USP pursuant to Section 2.2(a)(ii) above). In consideration for USP's
execution of the THVG2 Management Agreement, Baylor agrees to pay to USP, at the
Closing, cash in the amount of $1,928,571.

      2.3 ASSUMPTION OF CERTAIN OTHER LIABILITIES. THVG2 shall assume and shall
perform and discharge the liabilities and obligations (a) that were assumed by
USP pursuant to Section l(e) of the HealthFirst Purchase Agreement, as and to
the extent any such liability or obligation arises due to acts or omissions
occurring on or after the Effective Date, and (b) that arise on or after the
Effective Date under Sections l(c), l(d) (ii) (subject to Section 2.2(b) above),
2 (penultimate sentence only), 8(a)(iii) and (iv) (but only to the extent THVG2
is the indemnified party thereunder), 8(b) (subject to Section 8.8 hereof),
8(d), 8(e), 8(f) (if THVG2 exercises the HealthFirst Option included therein),
8(f)(iv) (if THVG2 does not exercise the HealthFirst Option included therein,
but only as to management fees accrued on and after the Effective Date of this
Agreement), 8(g) (if THVG2 exercises the HealthFirst Option included therein),
8(i)(iii), 8(k), 8(1) and 10 through 16, 18 and 19 of the HealthFirst Purchase
Agreement and Sections 1 and 2 through 5 (if THVG2 exercises the HealthFirst
Option included in Section 2) of the Option and Amendment Agreement included
therein, including without limitation all payment obligations arising under
Section 8(e) of the HealthFirst Purchase Agreement or resulting from any
exercise of a HealthFirst Option. In addition, THVG2 shall be subject to all
other relevant provisions of the HealthFirst Purchase Agreement in connection
with any

                                        8
<PAGE>
exercise of THVG2's rights and benefits thereunder. Except for the liabilities
and obligations described in this Section 2.3, THVG2 will not assume or be
liable for any other obligation or liability of USP, HealthFirst or any other
party to the HealthFirst Purchase Agreement due to any act or omission occurring
prior to the Effective Date, including without limitation: (i) any trade payable
that is more than 60 days past due; (ii) any claim or contingent liability
arising from the operations of DeSoto or Metroplex, or based upon any acts or
omissions of USP or its Affiliates, employees, agents or independent
contractors, or any other event that has occurred prior to the Effective Date,
including without limitation any malpractice claim, EEOC claim, workers'
compensation claim or other claim by any present or former employee; (iii)
liabilities or obligations of DeSoto or Metroplex arising under the Medicare or
Medicaid program or any other third party payor program; (iv) the costs and
expenses associated with this Agreement that, as provided in Section 10.4, are
to be borne by USP; (v) any federal, state or local income taxes or liabilities;
or (vi) any obligation, liability or claim as to which USP would have an
indemnity obligation under Section 13.1 hereof.

      3. CAPITAL CONTRIBUTION OBLIGATIONS. In order to provide the funds needed
by THVG2 to make the payments called for by Section 2 hereof (but subject to
Section 4 hereof), USP and Baylor agree as follows:

      (a) In consideration for the issuance to Baylor of a 49% membership
interest in THVG2, Baylor agrees to contribute to THVG2 on the Closing Date the
amount that THVG2 is required to pay to USP pursuant to Section 2.2(a) (ii).

      (b) USP and Baylor each agrees to contribute to THVG2 its pro rata share
(based upon their respective ownership interests in THVG2 at the time such
payment is due) of the amount needed by THVG2 to make any payment it is required
to make under the HealthFirst Purchase Agreement pursuant to Section 2.2(b)
hereof or Section 8(e) of the HealthFirst Purchase Agreement; provided, however,
that the parties acknowledge that Baylor's obligations under this Section 3(b)
and Section 3(c) are subject to its rights under Sections 4(b) and (d).

      (c) Subject to Sections 4(b) and (d), USP and Baylor each agrees to
contribute to THVG2 its pro rata share (based upon their respective ownership
interests in THVG2 as of the date any such payment IS due) of the amount needed
by THVG2 to make any payment that results from an exercise of a HealthFirst
Option by THVG2.

                                        9
<PAGE>
      4. ANNUAL RECONCILIATION 0F CAPITAL CONTRIBUTION OBLIGATIONS. Anything
herein or in the THVG1 Regulations or the THVG2 Regulations to the contrary
notwithstanding, the parties agree that, for their convenience, USP and Baylor
will prepare an annual reconciliation of their respective payment and capital
contribution obligations described in Sections 1, 2 and 3 hereof, upon the
following terms:

      (a) On the Closing Date and on each date that a payment called for by
subsection (i), (ii) or (iii) of Section 1.2(b) hereof is to be made, and on
each anniversary of the date the payment called for by Section 1.2(b) (iii)
hereof is made (each, a "Reconciliation Date"), USP and Baylor shall
reconcile all payment and capital contributions that they are required to have
made pursuant to this Agreement since the prior Reconciliation Date (or, with
respect to the first Reconciliation Date, that they are required to make on the
Closing Date).

      (b) THVG2 shall immediately give Baylor and USP notice if a payment
obligation of THVG2 referred to in Section 2.2(b) or 2.3(b) arises. Unless
Baylor elects otherwise within 10 days of such notice, USP shall fund 100% of
the payment obligations of THVG2 referred to in Sections 2.2(b) and 2.3(b) that
are due between Reconciliation Dates, which payments shall be treated for
accounting purposes as capital contributions made by USP. In such event, the
Ownership Interest of Baylor in THVG2 shall be diluted as of the date of each
such payment by USP and until the next Reconciliation Date for purposes of
allocations of profits and losses of THVG2 during such period (but not for
purposes of capital transactions, including additional capital contribution
obligations), all as provided in the THVG2 Regulations.

      (c) The following calculations shall be made on the Reconciliation Dates:

            (i) On the Closing Date, the amount due to Baylor pursuant to
      Section 1.2(a) shall be reduced by the amounts due from Baylor to USP
      pursuant to Section 2.2(c) and from Baylor to THVG2 pursuant to Section
      3(a), resulting in an amount due to Baylor from USP equal to $3,287,234
      (the "Closing Date Baylor Payment") Such payment shall satisfy the parties
      respective obligations under Sections 1.2(a), 2.2(a) (ii) , 2.2(c) and
      3(a) hereof.

            (ii) On each subsequent Reconciliation Date, USP and Baylor shall
      prepare an accounting (a "Reconciliation Statement") showing all of the
      payment

                                       10
<PAGE>
      obligations of USP and Baylor to and from each other, THVGl and THVG2
      pursuant to this Agreement. Each Reconciliation Statement shall show the
      amount that is necessary for USP to pay Baylor or for Baylor to pay USP
      (as the case may be) in order to fully satisfy all such payment
      obligations. For purposes of this Section 4(c), the payment due from USP
      to Baylor or from Baylor to USP is hereinafter referred to as the
      "Reconciliation Payment," the party that owes the Reconciliation Payment
      is referred to the "Shortfall Party" and the party that is to receive the
      Reconciliation Payment is referred to as the "Compensated Party." If
      Baylor is the Compensated Party, USP will cause the Reconciliation
      Statement to include a statement of the fair market value of USP Common
      Stock as of the date of the Reconciliation Statement. A sample
      Reconciliation Statement is attached hereto as SCHEDULE 4.

            (iii) Any dispute between USP and Baylor relating to a
      Reconciliation Statement shall be submitted to and resolved by THVG1's
      independent accounting firm, acting as an expert and not as an arbitrator.

      (d) The following shall apply to the Closing Date Baylor Payment and to
each Reconciliation Payment:

      (i) USP shall pay the Closing Date Baylor Payment by the issuance and
delivery to Baylor of a USP Parent Convertible Subordinated Promissory Note
("Convertible Note") in the amount of the Closing Date Baylor Payment, which
Convertible Note shall be convertible into USP Common Stock at an initial
conversion price of $3.50 per share and will be substantially in the form of
EXHIBIT C attached hereto.

      (ii) The Shortfall Party may elect, by giving written notice to the
Compensated Party within five business days after a Reconciliation Statement is
finalized, to make the Reconciliation Payment by suffering a dilution in its
ownership interest in either THVGl or THVG2 (as elected by the Shortfall Party)
in accordance with the procedures for such dilution set forth in the THVGl
Regulations or the THVG2 Regulations (as the case may be). In such event, the
Compensated Party shall be deemed to have made a capital contribution on the
Reconciliation Date to THVGl or THVG2 (as the case may be) in an amount equal to
the Reconciliation Payment.

      (iii) If the Shortfall Party does not make the election described in
subsection (ii) above, the Reconciliation Payment shall be paid promptly by the
Shortfall

                                       11
<PAGE>
Party to the Compensated Party; provided, however, that: (A) in the event that
Baylor is the Compensated Party with respect to a Reconciliation Statement
relating to the First Year, the Second Year or the Third Year, and if USP does
not elect to make the Reconciliation Payment by suffering dilution pursuant to
subsection (ii) above, Baylor shall have the right to elect, by giving written
notice to USP within five business days after the date that such Reconciliation
Statement is finalized, to receive all or any portion of the Reconciliation
Payment in the form of a USP Parent Convertible Note substantially in the form
of EXHIBIT C attached hereto, which Convertible Note shall be convertible into
USP Common Stock at an initial conversion price of $3.50 per share (subject to
adjustment as provided in the anti-dilution provisions of the Convertible Note
as if such Convertible Note had been issued on the Closing Date) with respect to
any Convertible Note issued on the Reconciliation Date relating to the First
Year and, for the Second and Third Years, at a conversion price equal to greater
of $3.50 per share (subject to such adjustment) or the fair market value of the
USP Common Stock as of the date such Convertible Note is issued (as determined
in good faith by the Board of Directors of USP Parent); (B) in the event that
Baylor is the Shortfall Party, Baylor shall have the further option (exercisable
by giving written notice of its election under this subsection (B) on the date
that the Reconciliation Payment is to be paid by Baylor) to pay the
Reconciliation Payment by reducing the outstanding principal amount of any
Convertible Note of USP Parent then held by Baylor; and (C) if Baylor is the
Shortfall Party, to the extent the Reconciliation Payment is created by Baylor's
election under Section 4(b) not to make a capital contribution to THVG2 that was
otherwise required in connection with an exercise of a HealthFirst Option or the
purchase by THVG2 of additional partnership interests in any partnership as to
which THVG2 (or any of its Subsidiaries) is then the general partner, then
Baylor shall be entitled to pay all or a portion of the Reconciliation Payment
by causing THVG2 to distribute to Baylor and USP (in accordance with their
respective Ownership Interests in THVG2 as of the prior Reconciliation Date) an
appropriate portion of such additional partnership interests that were so
acquired (as designated by USP) and then transferring the partnership interests
so acquired by Baylor through such distribution to USP, with the additional
partnership interests so transferred valued at the purchase price paid by THVG2
therefor; provided, further, that subsection (C) shall not apply if any such
transfers of partnership interests by THVG2 would (in the reasonable opinion of
USP) prevent USP from consolidating for financial accounting purposes with the
affected partnerships. In the event any such partnership interests are
transferred to USP pursuant to subsection (C), USP shall be entitled to hold,
vote, sell and otherwise deal with such additional partnership interests in its

                                       12
<PAGE>
sole discretion notwithstanding any contrary provisions set forth in any other
agreement or in the THVG2 Regulations (but, in any event, subject to any
restrictions set forth in the partnership agreement applicable to such
partnership interests).

      An example of the potential application of subsection (C) above is as
follows*.

      Assume that:

First Year purchase of Metroplex LP interests: $1,500,000**

First Year HealthFirst Option exercise price: $1,500,000**

First Year HealthFirst earn-outs: $1,200,000**

First Year Baylor earn-out owed by USP: $l,000,000

---------------------------
* For simplicity of presentation, this example assumes that the Ownership
Percentages in THVG2 are 50/50 rather than 51/49. ** 100% funded by USP pursuant
to Section 4(b).

      Then:

      Reconciliation Payment owed by Baylor (50% of [$1,500,000 + $1,500,000 +
$1,200,000] minus $1,000,000) = $1,100,000

      Baylor can elect to require THVG2 to distribute all of the $l,500,000 of
the additional Metroplex limited partnership interests acquired during the year
and satisfy $750,000 of its Reconciliation Payment by transferring its share of
those limited partner interests to asp. The remaining $350,000 can be paid
either in cash, by dilution in THVG2 or THVG1 or by reducing the Convertible
Note.

      (e) Notwithstanding any provisions of this Section 4 to the contrary, for
accounting and tax purposes, once a Reconciliation Payment is made or satisfied
in accordance with this Section 4: (i)USP and Baylor shall be deemed to have
made all payments to each other and capital contributions to THVG1 and THVG2
that were included in the Reconciliation Statement (except to the extent the
Shortfall Party has elected to suffer dilution pursuant to Section 4(d) (iii)
above); and (ii) THVG1 and THVG2 shall be deemed to have made the payments to
Baylor and USP required by this Agreement that were included in such
Reconciliation Statement.

                                       13
<PAGE>
      5. SALES TAX AND FILING FEES. THVGl and THVG2 (as the case may be) shall
pay any sales tax, filing fee or other similar tax or fee associated the sale of
the Baylor Center Assets to THVG1, the transfer of the USP Assets to THVG2 or
the assumption of liabilities pursuant to Sections 1.3, 2.2(b) and 2.3. It is
not anticipated that the transactions contemplated by this Agreement will result
in the imposition of any such tax or fee.

      6. CLOSING AND EFFECTIVE DATE. The "Closing" referred to herein will take
place at the offices of Baylor at 2:00 p.m., local time, on June 1, 1999, or on
the fifth business day following the satisfaction of the conditions to the
Closing described in Sections 11 and 12 hereof, whichever is later, or at such
other place or at such other date and time as the parties hereto shall agree.
Such time and date are referred to herein as the "Closing Date. " Regardless of
when the Closing occurs, it shall be effective as of 12:01 a.m. June 1, 1999
(the "Effective Date"). The parties hereto agree to acknowledge and use said
Effective Date for all purposes, including for accounting and federal and state
tax reporting purposes. Except as provided in Section 14 hereof, failure to
consummate the Closing on the date and time and at the place selected pursuant
to this Section 6 shall not result in the termination of this Agreement and
shall not relieve any party to this Agreement of any obligation hereunder.

      7. [INTENTIONALLY OMITTED.]

Texas and Delaware, respectively. Each of Desoto, Metroplex, Irving and Fort
Worth is a limited partnership that is duly organized and validly existing under
the laws of the State of Texas. DSP is a general partnership that is duly

and the shareholders

                                       14
<PAGE>
of USP and USP Parent and constitutes the valid and binding obligation of USP
and USP Parent. No provisions exist in any agreement to which USP or USP Parent
or any of their Restricted Affiliates (including without limitation the
Partnerships) is a party or by which any of their assets are bound which would
be violated by the execution, delivery or consummation of this Agreement or the
transactions contemplated hereby.

      8.3. TITLE TO THE USP ASSETS.

      (a) USP has good title to all of the USP Assets, subject to no mortgage,

applicable federal and state securities laws, (iii) the terms of the HealthFirst
Purchase Agreement, (iv) liens for taxes not yet due or that are being contested
in good faith, (v) liens pursuant to agreements listed in the Schedules to this

the Partnerships, the Surgery Centers and the HealthFirst Management Agreements.

      (b) All outstanding partnership interests in DeSoto and Metroplex are
currently held as set forth in Schedule 7 to the HealthFirst Purchase Agreement.
USP is not subject to any options or other rights to purchase or sell any
partnership interest in Metroplex or DeSoto (other than as set forth in Section
8(e) of the HealthFirst Purchase Agreement), and neither Metroplex nor DeSoto
has any binding obligation to issue or sell any partnership interest. USP is
currently the sole general partner of both DeSoto and Metroplex, and the
partnership interests in DeSoto and Metroplex owned by USP are duly authorized
and validly issued Partnership Interests. USP has not breached and, to the
knowledge of USP, no other partner of either DeSoto or Metroplex has breached
any provision of, and there are no facts or circumstances which would reasonably
indicate that USP or (to the knowledge of USP) any other partner of DeSoto or
Metroplex will or may be in default or breach under, the respective Limited
Partnership Agreements of DeSoto and Metroplex, which breach or default would
have a material adverse effect on USP, Metroplex or DeSoto.

      (c) DeSoto and Metroplex each has good title to its respective assets
shown on its balance sheet included in

                                       15

lessors in leased assets, (ii) liens for taxes not yet due or that are being
contested in good faith, (iii) liens pursuant to the agreements listed on
Schedules to this Agreement and (iv) other liens, the existence of which, in the

assets owned or leased by DeSoto and Metroplex, respectively, constitute all of
the assets currently in existence that are being used in their respective
businesses, other than assets held by USP that it uses to provide services under
the respective HealthFirst Management Agreements with DeSoto and Metroplex or to
provide other services to DeSoto and/or Metroplex (which services USP will
continue to provide pursuant to the THVG2 Management Agreement).

      8.4 FINANCIAL STATEMENTS. USP has delivered to Baylor copies of the

attached hereto as SCHEDULE 8.4): (a)unaudited balance sheet as of February 28,
1999 (the "Balance Sheet Date"); (b) unaudited statement of operations for the
two month period ended on the Balance Sheet Date; and (c) unaudited balance

accordance with generally accepted accounting principles consistently applied

present fairly the financial condition of DeSoto and Metroplex, respectively, as

referenced balance sheets, (ii) liabilities created by the agreements described

obligation of the types described in Sections 2.3(i)-(iii) and (v). Each of
DeSoto and Metroplex is and as of the Closing Date will be current in all
payment obligations to which it is subject, other than trade payables that are
not more than 60 days past due.

      8.5 LICENSING 0F SURGERY CENTERS. The Surgery Centers owned and operated
by DeSoto and Metroplex, respectively, are licensed by the Texas Department of
Health Services ("TDH") as freestanding facilities. Subject to obtaining the
approval of TDH with respect to the change of ownership of the Transferred
Partnership Interests contemplated by this Agreement and the other approvals
listed in SCHEDULE 8.16, USP is not aware of any

                                       16
<PAGE>
reason that DeSoto and Metroplex will not be able to continue to operate such
Surgery Centers upon transfer of the Transferred Partnership Interests to THVG2
as contemplated hereby.

      8.6 CONTRACTS. USP has delivered to Baylor an accurate list (attached
hereto as SCHEDULE 8.6) of all material contracts, leases and instruments to

or by which any assets of DeSoto or Metroplex are bound, including without
limitation the following: (a) all real estate leases, equipment leases and

Metroplex); (d) all employment and consulting agreements; (e) all agreements
with employers, health maintenance organizations, insurance companies, preferred
provider organizations and other managed care entities whereunder DeSoto or
Metroplex provides surgery center services; and (f) contracts to which USP is a
party that are material to the performance of USP's obligations under the
HealthFirst Management Agreements or by which any assets of USP material to such
performance are bound; provided, however, that SCHEDULE 8.6 need not include
contracts that do not involve a non-cancellable financial commitment of more
than $25,000 and are cancellable without cost or penalty no later than 12 months
after the Closing Date. No Partnership is (i) obligated to take any action that
would violate the THVG2 Regulations or (ii) obligated to not take any action
that is required by the THVG2 Regulations. USP has delivered or made available
to Baylor or its counsel true and complete copies of the documents described in
SCHEDULE 8.6. All of the agreements, contracts, leases and instruments listed in
SCHEDULE 8.6 are valid and binding, and neither DeSoto, Metroplex, USP nor any
of USP's Affiliates has breached and, to the knowledge of USP, no other party
thereto has breached any provision of, and there are no facts or circumstances
known to USP which would reasonably indicate that DeSoto, Metroplex, USP or any
of USP's Affiliates will or may be in such breach under, any such agreement,
contract, lease or instrument, which invalidity or breach would have a material
adverse effect on DeSoto, Metroplex or USP (with respect to USP's operation of
the HealthFirst Management Agreements). Each of the HealthFirst Management
Agreements is in full force and effect and represents the binding obligations of
the parties thereto. USP is the sole manager or similar party under each of the
HealthFirst Management Agreements. Except as described in SCHEDULE 8.6, neither
USP, any USP Affiliate nor any Partnership is in breach of the terms

                                       17
<PAGE>
of, and there are no facts or circumstances known to USP which would reasonably
indicate that USP, any USP Affiliate or any Partnership will or may be in breach
of its obligations under, any HealthFirst Management Agreement.

      8.7 LITIGATION AND PROCEEDINGS. Except for malpractice claims arising
before the Effective Date covered by insurance policies, there are no legal
claims, actions, suits, arbitrations or other legal, administrative or
governmental proceedings pending or, to USP's knowledge, threatened against
DeSoto or Metroplex or their respective properties, assets or business, and to
USP's knowledge no facts exist which might form the basis for any such claim,
action, suit or other proceeding, other than claims, actions, suits or other
proceedings that, in the aggregate, will not have a material adverse effect on
DeSoto or Metroplex. The operations of DeSoto and Metroplex have not caused
DeSoto or Metroplex to be in default with respect to any judgment, order or
decree of any court, governmental agency or instrumentality. Neither USP nor any
of its Affiliates is a party to any litigation that would materially affect the
HealthFirst Management Agreements.

      8.8 COMPLIANCE WITH LAW AND INSTRUMENTS. The business and operations of
DeSoto and Metroplex each have been and are being conducted in material
compliance with all applicable laws, rules, regulations and licensing
requirements of all authorities, the violation of which, individually or in the
aggregate, would materially affect in any way the business of DeSoto or
Metroplex. USP is unaware of any facts which might form the basis for a claim
that any such violation exists. USP is in compliance in all material respects
with all of its material obligations that have arisen to date under the
HealthFirst Purchase Agreement. The business and operations of USP in performing
its obligations under the HealthFirst Management Agreements have been and are
being conducted in material compliance with all applicable laws, rules,
regulations and licensing requirements of all authorities, the violation of
which, individually or in the aggregate, would materially affect USP's ability
to receive the benefits of the HealthFirst Management Agreements in any way.
DeSoto and Metroplex each meets in all material respects the conditions for
participation in the Medicare and Medicaid programs. Neither the U.S. Department
of Health and Human Services nor any state agency has conducted, or has given
USP, DeSoto or Metroplex any notice that it intends to conduct, any audit or
other review of the participation of DeSoto or Metroplex in the Medicare and
Medicaid programs (other than annual surveys, reviews and audits), and no such
audit or review would result in any material liability by DeSoto or Metroplex
for any reimbursement, penalty or interest

                                       18
<PAGE>
with respect to payments received by DeSoto or Metroplex thereunder.

      8.9 ACCOUNTS RECEIVABLE. All of the accounts receivable of DeSoto and
Metroplex are and will be valid and enforceable claims and are not subject to
any defenses, offsets, claims or counterclaims. Notwithstanding the foregoing,
USP expressly makes no warranty or guaranty as to the collectibility of such
accounts receivable.

      8.10 ABSENCE OF SPECIFIED CHANGES. Except as provided on SCHEDULE 8.10 and
except for the transactions provided for herein, since the Balance Sheet Date
there has not been (a) any transaction by DeSoto or Metroplex relating to or

strike or work stoppages by any employees of DeSoto, Metroplex or USP.

      8.12 INSURANCE POLICIES. USP has policies of insurance in effect for
DeSoto and Metroplex, and each of Irving and DSP has policies of insurance in
effect, in such amounts and insuring against such losses and risks as are normal
for their business, including without limitation medical malpractice insurance
coverage.

      8.13 NO BROKERS OR FINDERS. As a result of any act or failure to act by
USP, USP Parent or any of their agents, no person or entity has, or as a result

commission, fee or other compensation as a broker, finder or any similar
capacity.

Affiliates will not be subject to any such noncompetition covenant or
restrictive agreement by virtue of THVG2's acquisition of the USP Assets.

assets, (b) liens for taxes not yet due or that are being contested in good
faith, (c) liens pursuant to agreements listed on the Schedules to this

Baylor Centers as of the Balance Sheet Date. Except for (i) the liabilities
reflected in the above referenced balance sheets, (ii) liabilities created by
the agreements described in SCHEDULE 9.6 attached hereto and (iii) other
obligations incurred in the ordinary course of business since March 31, 1999,

hereto as SCHEDULE 9.6) of all material contracts, leases (excluding the current
real property leases relating to the facilities in which the Baylor Centers are
located and managed care contracts or arrangements covering services provided by
a Baylor Center and one or more facilities other than the Baylor Centers, as to

<PAGE>

Baylor Center Assets are bound, including without limitation the following: (a)

agreements relating to the purchase of equipment; (c) all agreements with any

organizations, insurance companies, preferred provider organizations and other
managed care entities whereunder a Baylor Center (and only one or both Baylor
Centers) provides surgery center services; provided, however, that SCHEDULE 9.6
need not include contracts that do not involve a non-cancellable financial
commitment of more than $25,000 and are cancellable without cost or penalty no
later than 12 months after the Closing Date. There are no managed care contracts
that relate only to services provided by the Baylor Centers. Baylor has
delivered to USP or its counsel true and complete copies of the documents
described in SCHEDULE 9.6. All of the agreements, contracts, leases and
instruments listed in SCHEDULE 9.6 are valid and binding, and neither Baylor nor
any of its Affiliates has breached and, to the knowledge of Baylor, no other
party thereto has breached any provision of, and there are no facts or
circumstances known to Baylor which would reasonably indicate that Baylor or any
of its Affiliates will or may be in such breach under, any such agreement,
contract, lease or instrument, which invalidity or breach would have a material
adverse effect on any Baylor Center.

      9.7 LITIGATION AND PROCEEDINGS. Except for malpractice claims arising
before the Effective Date covered by self-insurance programs of Baylor and its
Affiliates or insurance policies (the responsibility for which shall be retained
by Baylor) and as described in SCHEDULE 9.7, there are no legal claims, actions,
suits, arbitrations or other legal, administrative or governmental proceedings
pending or, to Baylor's knowledge, threatened against Baylor relating to or
affecting either of the Baylor Centers or the Baylor Center Assets, and to
Baylor's knowledge no facts exist which might form the basis for any such claim,
action, suit or other proceeding, other than claims, actions, suits or other
proceedings that, in the aggregate, will not have a material adverse effect on
any Baylor Center. Baylor's operation of the Baylor Centers has not caused
Baylor to default with respect to any judgment, order or decree of any court,
governmental agency or instrumentality.

Baylor is unaware of any facts which might form the basis for a claim that any
such violation exists. Each Baylor Center meets in all material respects the
conditions for participation in the Medicare and Medicaid programs. Neither the
U.S. Department of Health and Human Services nor any state agency has conducted,
or has given Baylor or its Affiliates any notice that it intends to conduct, any
audit or other review of a Baylor Center's participation in the Medicare and
Medicaid programs (other than annual surveys, reviews and audits), and no such
audit or review would result in any material liability by Baylor or its
Affiliates for any reimbursement, penalty or interest with respect to payments
received by Baylor or its Affiliates thereunder.

      9.9 ACCOUNTS RECEIVABLE. All of the accounts receivable of the Baylor
Centers are and will be valid and enforceable claims and are not subject to any

accounts receivable.

      13.1 INDEMNIFICATION.

      (a) USP hereby covenant and agrees that it will indemnify and hold Baylor
at all times harmless from and against any loss, damage and expense (including
reasonable attorneys' fees and other costs of defense) caused by or arising out
of or in connection with (i) any liability or obligation arising out of the
business of USP as conducted on or before the Effective Date that is not
expressly assumed by THVG2 pursuant to Section 2.3 or

                                       35
<PAGE>
(ii) any misrepresentation, breach of warranty or nonfulfillment of any covenant
made by USP under or pursuant to this Agreement.

      (b) Baylor hereby covenants and agrees that it will indemnify and hold USP
at all times harmless from and against any loss, damage and expense (including
reasonable attorneys' fees and other costs of defense) caused by or arising out
of or in connection with (i) any liability or obligation arising out of the
business of the Baylor Centers as conducted on or before the Effective Date that
is not expressly assumed by the THVG1 pursuant to Section 1.3 or (ii) any
misrepresentation, breach of warranty or nonfulfillment of any covenant made by
Baylor under or pursuant to this Agreement.

      (c) Any party that intends to enforce an indemnity obligation shall give
the indemnifying party notice of any claim as soon as possible, but the failure
to give such notice shall not constitute a waiver or release of the indemnifying
party and shall not affect the rights of the indemnified party to recover under
this indemnity, except to the extent the indemnifying party is prejudiced
thereby.

      (d) In connection with any claim giving rise to indemnity under this
Section 13.1 resulting from or arising out of any claim or legal proceeding by a
person who is not a party to this Agreement, the indemnifying party, at its sole
cost and expense, may, upon written notice to the indemnified party, assume
control of the defense of such claim or legal proceeding, to the extent that the
indemnifying party admits in writing its indemnification liability to the
indemnified party with respect to all material elements thereof. If the
indemnifying party assumes the defense of any such claim or legal proceeding,
the obligations of the indemnifying party hereunder as to such claim or legal
proceeding shall be to take all steps necessary in the defense or settlement
thereof and to hold the indemnified party harmless from and against any losses,
damages, expenses or liability caused by or arising out of any settlement
approved by the indemnifying party and the indemnified party or any judgment in
connection with such claim or legal proceeding. Each indemnified party agrees
that it will cooperate with the indemnifying party in the defense of any such
action, the defense of which is assumed by the Indemnifying Party. Except with
the consent of the indemnified party, which consent may be withheld at the
indemnified party's sole discretion, the indemnifying party shall not consent to
any settlement or the entry of any judgment arising from any such claim or legal
proceeding which, in each case, does not include as an unconditional term
thereof the delivery by the claimant or the plaintiff to the indemnified party
of a release from all liability in respect thereof. The

                                       36
<PAGE>
indemnified party shall be entitled to settle any claim without the consent of
the indemnifying party where the settlement does not obligate the indemnifying
party to pay any monetary damages or obligate or restrict the Indemnifying Party
in any way. If the indemnifying party does not assume the defense of any claim
or litigation, any indemnified party may defend against such claim or litigation
in such manner as it may deem appropriate, including but not limited to settling
such claim or litigation, after giving notice of the same to the indemnifying
party, on such terms as the indemnified party may deem appropriate. The
indemnifying party will, promptly after any of the same is incurred, reimburse
the indemnified party in accordance with the provisions hereof for all damages,
losses, liabilities, costs and expenses incurred by the indemnified party.

      13.2 NO-SHOP CLAUSE. Unless and until this Agreement is terminated in
accordance with Section 14, neither USP nor Baylor will, without the approval of
the other, (a) offer for sale the USP Assets or the Baylor Center Assets (or any
material portion thereof), (b) solicit offers to buy all or any material portion
of such assets, (c) hold discussions with any other party looking toward such an
offer or solicitation or, looking toward a merger or consolidation of any
entity that directly owns any such assets or (d) enter into any agreement with
any other party with respect to the sale or other disposition of the USP Assets
or the Baylor Center Assets or any material portion thereof or with respect to
any merger, consolidation or similar transaction involving any entity that
directly owns any of such assets.

      13.3 PROPOSED SYNDICATION 0F BAYLOR LIMITED PARTNERSHIP. USP, Baylor and
THVGl acknowledge and agree that it is their intention to conduct a syndication
of limited partnership interests in the Baylor Limited Partnership on
substantially the following terms and conditions: (a) the Baylor limited
Partnership will offer Limited Partnership Units representing up to a 25%
interest in the Baylor Limited Partnership; (b) all of the proposed offerees
will be physicians who are on the medical staff of one or both of the Baylor
Centers or who have agreed to apply to join the medical staff of one or both of
the Baylor Centers; (c) the investors in the offering will be subject to the
mutual approval of USP and Baylor; (d) the offering price for the Limited
Partnership Units will be based upon an evaluation of the Baylor Limited
Partnership that is mutually acceptable to Baylor and USP; and (e) the proceeds
of this syndication shall be distributed by the Baylor Limited Partnership to
the Baylor Center General Partner and to Baylor and USP (subject to any
retention by THVG1 approved by its members).

                                       37
<PAGE>
      13.4 EXERCISE OF HEALTHFIRST OPTIONS. In the event that Baylor elects to
cause THVG2 not to exercise any HealthFirst Option, or if Baylor does not
consent to allow THVG2 to exercise any HealthFirst Option within 30 days prior
to the expiration of such HealthFirst Option, such HealthFirst Option shall be
deemed to have been conveyed to USP and USP shall be free to exercise such
HealthFirst Option and to own the assets acquired thereby (and any other
partnership interest in the partnership that is the subject of such HealthFirst
Option thereafter acquired by USP) independent of THVG1, THVG2, Baylor and its
affiliates notwithstanding any contrary provisions set forth in the THVGl
Regulations, the THVG2 Regulations or any other agreement that may otherwise be
applicable. USP shall not be obligated to pay any consideration to THVG2 or
Baylor for the transfer of any such HealthFirst Option to USP pursuant to this
Section 13.4. Nothing in this Section 13.4, or any transfer of a HealthFirst
Option to USP pursuant hereto, shall affect any Management Agreement between
THVG2 and the partnership that is the subject of such HealthFirst Option or the
THVG2 Management Agreement as it relates to Baylor and USP providing services to
THVG2 in connection with such Management Agreement between THVG2 and such
partnership.

      13.5 GUARANTEES 0F USP PARENT AND BHCS. By their execution of this
Agreement as set forth on the signature pages hereof, (a) USP Parent hereby
guarantees the performance of the obligations of USP that arise under this
Agreement and (b) BHCS hereby guarantees the performance of the obligations of
Baylor that arise under this Agreement. The guarantees set forth herein are
intended to be guarantees of performance and not merely of collection. If the
proposed Southwest Health System transaction closes, BHCS may assign its
obligations under this Section 13.5 to Baylor University Medical Center, a Texas
non-profit corporation ("BUMC"). Notwithstanding the foregoing, however, the
obligations guaranteed by USP Parent and BHCS pursuant hereto are limited to
those that arise under this Agreement and shall not include the obligations of
USP and Baylor, respectively, that arise under the THVGl Regulations or the
THVG2 Regulations or any other obligations that arise outside of this Agreement.

      13.6 POSSIBLE ACQUISITION 0F BAYLOR IRVING SURGERY CENTER BY THVG1. Baylor
will use reasonable efforts to arrange for the purchase by THVGl of the assets
of Baylor Irving Surgery Center from its current owner, Baylor Medical Center at
Irving (which is affiliated with Baylor), if and when Baylor Irving Surgery
Center is licensed as a freestanding surgery center. The purchase price will be
negotiated between USP and said owner and will be subject to approval of the
Managers of THVGl in accordance with the THVGl Regulations. The terms of
purchase

                                       38
<PAGE>
shall otherwise be substantially similar to those set forth herein relating to
the acquisition of the Baylor Center Assets by THVG1.

      13.7 USP PARENT STOCKHOLDERS AGREEMENT AND REGISTRATION RIGHTS AGREEMENT.
On the Closing Date, Baylor, USP Parent and certain other Persons will enter
into (a) an amendment, in the form of EXHIBIT H attached hereto, to USP Parent's
Amended and Restated Stockholders Agreement, and (b) an amendment, in the form
of EXHIBIT I attached hereto, to USP Parent's Amended and Restated Registration
Rights Agreement.

      13.8 USP BOARD OF DIRECTORS REPRESENTATIVE. At all times prior to the
earlier of (a) the initial sale by USP Parent of any class of its equity
securities pursuant to a registration statement filed under the Securities Act
of 1933, as amended, or (b) the registration of the USP Common Stock under the
Securities Exchange Act of 1934, as amended, and so long as Baylor and its
Affiliates own at least a 30 percent interest in THVG1, Baylor shall have the
right to designate, subject to the reasonable approval of the Board of Directors
of USP Parent, an officer of BHCS who is at the Senior Vice President level or
above to the Board of Directors of USP Parent. USP and USP Parent will use
reasonable efforts to cause such designee to be elected to USP Parent's Board of
Directors. The parties acknowledge and agree that Baylor has initially
designated, and the USP Parent Board of Directors has approved, Boone Powell as
Baylor's representative on the USP Parent Board of Directors.

      13.9 MEDICAL DIRECTORS. The parties hereto acknowledge and agree that: (a)
Robert Rehmet, M.D. will be offered the position of Medical Director of Baylor
Surgicare at his current rate of compensation for a minimum term of three years
from the Effective Date; (b) Tom Swygert, M.D. will be offered the position of
Medical Director of Texas Surgery Center at his current level of compensation
for a minimum period of three years from the Effective Date; and (c) USP will
offer to Dr. Rehmet the position of Regional Medical Director for the North
Texas Region for compensation to be agreed upon by USP and Dr. Rehmet (which
shall include stock options in USP Parent in accordance with the polices and
procedures of USP Parent with respect to the grant of stock options to
equivalent officers), but such employment shall not be subject to an employment
agreement and shall be terminable at will by either USP or Dr. Rehmet.

      13.10 DEVELOPMENTS OUTSIDE OF NORTH TEXAS. USP and Baylor acknowledge and
agree that the THVG1 Regulations and

                                       39
<PAGE>
the THVG2 Regulations include certain restrictions on their ability to own and
operate outpatient surgical facilities within the North Texas Region. In
addition, from time to time during the period beginning on the date hereof and
ending on June 1, 2002, Baylor and its Affiliates may (but shall not be
obligated to) make introductions and otherwise assist USP and its Affiliates in
locating potential development or acquisition opportunities for outpatient
surgical facilities outside of the North Texas Region. If USP or any of its
Affiliates develops or acquires an outpatient surgical facility as a result of
or in connection with an opportunity so presented to USP by Baylor or its
Affiliates, and if USP or any Affiliate was not already involved in sharing
information related to the opportunity prior to such presentation to USP, USP
will pay Baylor a fee equal to the lesser of $100,000 or 3% of the capital cost
incurred by USP and its Affiliates in acquiring or developing such outpatient
surgical facility. Any such fee shall be payable in cash concurrently with the
acquisition of or, in the case of a development, the opening of such surgical
facility. In order for Baylor to receive credit for this fee, Baylor must
present the opportunity in writing and disclose Baylor's relationship (if any)
with the project. USP will respond in writing to all such opportunities
presented by Baylor within 30 days after the receipt of such written
information. If Baylor has or acquires any ownership interest in, or is to
receive any other fee with respect to, the acquisition or development of the
proposed outpatient surgical facility, no fee shall be payable to Baylor
pursuant to this Section 13.10.

      13.11 POTENTIAL CONSOLIDATION 0F USP WITH THVG1 AND/OR THVG2. Baylor
acknowledges that an important element of the transactions provided for in this
Agreement is that USP intends to consolidate with THVG2 for financial accounting
purposes. In addition, USP would like to explore opportunities in the future to
consolidate with THVG1. To the extent that any of the proposed terms set forth
in this Agreement or in the THVG2 Regulations would prevent or significantly
impair USP's ability to so consolidate with THVG2, Baylor will negotiate in good
faith with USP to modify such terms so as to allow such consolidation. In
addition, if future interpretations of accounting guidelines have the effect of
permitting USP to consolidate with THVG1 for financial accounting purposes while
still allowing Baylor to retain its required control of THVG1 under applicable
federal tax laws and regulations (as interpreted by Baylor) then the parties
will agree to negotiate in good faith to modify such terms so as to allow such
consolidation.

      13.12 USE 0F BAYLOR NAME AND LOGO. Subject to the approval of Baylor
University and execution of an acceptable

                                       40
<PAGE>
sublicense agreement, the Baylor Limited Partnership shall be entitled to
continue to use the name "Baylor" with respect to the Baylor Center currently
known as "Baylor Surgicare. "Baylor agrees to use reasonable efforts to obtain
such approval of Baylor University. However, the approval is in Baylor
University's sole discretion, and Baylor can not guarantee that the approval
will be obtained. In any event, the Baylor Limited Partnership shall be
entitled, subject to the execution of an acceptable license or sublicense
agreement, as applicable, to state that the Baylor Centers are "affiliated with
Baylor" and to use Baylor's "flame" logo in connection with the business of the
Baylor Centers. Baylor and THVG1 will prepare and enter into a related
sublicensing agreement (which agreement will not require THVG1 or the Baylor
Limited Partnership to pay any additional fee or other charge).

      14. TERMINATION.

      14.1 BY MUTUAL CONSENT. This Agreement may be terminated without further
obligation of the parties at any time prior to Closing by mutual consent of the
parties hereto.

      14.2 DAMAGES. No party shall be liable in damages to any other party as a
result of the failure to consummate the transactions contemplated by this
Agreement unless such failure is caused by the material breach by such party of
any of the terms of this Agreement.

      14.3 UNILATERAL TERMINATION. If, through no fault of or breach by a party
hereto, the transactions contemplated hereby have not been consummated on or
before June 2, 1999, this Agreement may be terminated by written notice given by
any such non-breaching party to the other parties without further obligation of
the parties.

      15. CONFIDENTIALITY. In the event that this Agreement is terminated
pursuant to Section 14 hereof, or otherwise, or the Closing does not occur by
reason of failure of one of the conditions to the Closing, the parties hereto
agree (a) to return to the other parties all originals and copies of all
documents, financial statements and other information furnished or copied in
connection with the transactions contemplated by this Agreement and (b) not to
disclose without the prior written consent of the disclosing party any
information obtained with respect to the business or operations of the
disclosing party or any affiliate of such party.

be governed by and construed and enforced in accordance with the laws of the

or to affect the meaning or interpretation of this Agreement in any way.

      18. GENERAL. This Agreement (including the Exhibits and Schedules attached
hereto and the other documents and agreements referred to herein) sets forth the
entire agreement and understanding of the parties with respect to the
transactions contemplated hereby, and supersedes all prior agreements,
arrangements and understandings related to the subject matter hereof. No
representation, promise, inducement or statement of intention has been made by
any party hereto which is not embodied in this Agreement, or in the Exhibits and
Schedules attached hereto or the written statements, certificates or other
documents delivered pursuant hereto. All of the terms, provisions, covenants,
representations, warranties and conditions of this Agreement shall survive the
Closing and shall be binding upon and inure to the benefit of and be enforceable
by the parties hereto and their respective successors and assigns. This
Agreement may be amended, modified, superseded or canceled, and any of the
terms, provisions, covenants, representations, warranties or conditions hereof
may be waived, only by a written instrument executed by all parties hereto or,
in the case of a waiver, by the party waiving compliance. The failure of any
party at any time or times to require performance of any provision hereof shall
in no manner affect the right to enforce the same. No waiver by any party of any
condition, or of the breach of any term, provision, covenant, representation or
warranty contained in this Agreement, whether by conduct or otherwise, in any
one or more instances, shall be deemed to be or construed as a further 0f
continuing waiver of any such condition or breach or a waiver of any other
condition or of the breach of any other term, provision, covenant,
representation or warranty. In the event that any one or more of the provisions
of this Agreement shall be held or otherwise found to be invalid, illegal or
unenforceable, all other provisions hereof shall be given effect separately
therefrom and shall not be affected thereby. No party hereto shall assign any of
its rights or obligations hereunder without the prior written consent of the
other parties; provided, however, that without such consent, Baylor may assign
its rights and obligations under Section 1.2(b) hereof to a Person to which
Baylor may assign its membership interests in THVGl under Section 4.1(a) of the
THVGl Regulations, as amended. This Agreement is for the sole benefit of the
undersigned parties hereto and is not for the benefit of any third party.

      19. FURTHER ASSURANCES. USP and Baylor each agrees to execute and deliver
such other documents and instruments and take such other actions as any party
hereto may reasonably request in order more fully to vest in THVGl and THVG2,
and to perfect their title and interest in and to, the Baylor Center Assets and
the USP Assets, respectively.

      20. COUNTERPARTS. Separate copies of this Agreement may be signed by the

pay the successful party or parties all costs, expenses and reasonable
attorneys' fees incurred therein by such party or parties (including without
limitation such costs, expenses and fees on any appeal or in connection with any
bankruptcy proceeding), and if the successful party recovers judgment in any
such action or proceeding, such costs, expenses and attorneys' fees shall be
included in and as a part of such judgment.

      22. DISPUTE RESOLUTION MECHANISMS. The parties have agreed on the
following mechanisms in order to obtain prompt and expeditious resolution of
disputes hereunder (other than a dispute relating to any calculation of EBITDAM
pursuant to Section 1.2(b), which shall be resolved as provided therein):

      22.1 BINDING ARBITRATION. If any dispute arises between the parties with
respect to the interpretation or enforcement of this Agreement, the parties
agree to work in good faith to resolve such dispute or disagreement in good
faith and, if they are unable to resolve the dispute, they shall submit it to
binding arbitration.

      22.2 CHOICE 0F ARBITRATOR. If the parties can agree to a single arbitrator
within 30 days of one party receiving notice from the other party of the dispute
or disagreement, such arbitrator shall be chosen. The arbitrator(s) shall not be
required to have qualifications other than a reasonable amount of experience and
specialty in the area which is the subject of the dispute.

                                       44

      22.3 FAILURE TO CHOOSE ARBITRATOR. If the parties do not agree as to the
choice of an arbitrator, each party shall choose an arbitrator within 10 days
after the expiration of the 30 day period referred to in Section 22.2 and those
chosen arbitrators shall choose an additional arbitrator within 20 days of the
date in which the last arbitrator is chosen. If at the end of said 20 days the
parties' designated arbitrators cannot agree on the selection of the third
arbitrator, such selection shall be made by the American Arbitration Association
upon the application of either party.

      22.6 EFFECT 0F ARBITRATION. The decision of the arbitrator(s) shall be
final and binding on the parties.

      23. INTERPRETATION 0F AGREEMENT. The parties hereto acknowledge and agree
that this Agreement has been negotiated at arm's length and between parties
equally sophisticated and knowledgeable in the matters dealt with in this
Agreement. Accordingly, any rule of law or legal decision that would require
interpretation of any ambiguities in this Agreement against the party that has
drafted it is not applicable and is waived. The provisions of this Agreement
shall be interpreted in a reasonable manner to effect the intent of the parties
as set forth in this Agreement.

           SELLER                      PARTNERSHIP
           ------                      -----------
           HFMA                        DeSoto Surgicare Partners, Ltd.,
                                       a Texas limited partnership
                                       ("DeSoto")

           HFMB                        Metroplex Surgicare Partners,
                                       Ltd., a Texas limited
                                       partnership ("Metroplex")

           HFMD                        Irving Surgery Center, Ltd., a
                                       Texas limited partnership
                                       ("Irving")

           VVSC                        Dallas Surgery Partners, a Texas
                                       general partnership ("DSP")

           HFMFW                       Fort Worth Surgicare Partners,
                                       Ltd., a Texas limited
                                       partnership ("Fort Worth")

The above named partnerships are sometimes hereinafter collectively referred to
as the "Partnerships" and, individually, as a "Partnership". DeSoto, Metroplex
and Irving are sometimes hereinafter collectively referred to as the "Initial
Partnerships". The partnership agreements of the Partnerships, which are more
fully described in Schedule 9 attached hereto, are sometimes hereinafter
collectively referred to as the "Partnership Agreements". HFMA, HFMB, HFMD and

                                       1
<PAGE>

HFMFW (which are hereinafter collectively referred to as the "Former Owners"
and, individually, as a "Former Owner") have assigned the ownership interests
held by each such Former Owner in the Partnership in which such Former Owner was
a general partner (the "Associated Partnership") to Forest Edge and Oak Mount,
whose current ownership interests in the Partnerships are set forth in Schedule
1 attached hereto.

            B. The Principals are the sole members of HealthFirst and HFMFW and
own 100% of the issued and outstanding stock of HFMA, HFMB and HFMD. The
Principals own the percentage of the issued and outstanding stock of VVSC
described in Schedule 1.

            C. Each of the Partnerships owns and operates an ambulatory surgery
center in the Dallas/Ft. Worth area. The outpatient surgery centers owned and
operated by the Partnerships are sometimes hereinafter referred to collectively
as the "Surgery Centers" and, individually, as a "Surgery Center".

            D. Prior to the formation of Bingham Management and Disney
Management (the "Management Sellers"), HealthFirst provided management services
to each of the Partnerships pursuant to either a direct Management Agreement
between HealthFirst and such Partnership or through the assignment of a
Management Agreement entered into by a Former Owner or VVSC with its Associated
Partnership. All of HealthFirst's rights, interests and obligations under such
Management Agreements have been assigned to and assumed by the Management
Sellers, Such Management Agreements are hereinafter collectively referred to as
the "HealthFirst Management Agreements".

            E. Certain of the Partnerships lease the real property associated
with their respective Surgery Centers. Schedule 2 attached hereto identifies the
real property (if any) that is owned by each Partnership and, where applicable,
the lessor, lessee and each of the real property lease agreements (including all
amendments) to which each of the Partnerships is a party. The lease agreements
identified in Schedule 2 are sometimes hereinafter collectively referred to as
the "Real Property Leases", and the real property covered thereby, together with
real property that is owned by any of the Partnerships, is sometimes hereinafter
collectively referred to as the "Real Property".

            F. Subject to the terms and conditions set forth herein, Sellers
have agreed to sell and Buyer (either directly or through a wholly owned
subsidiary that it may form for purposes of such acquisitions) has agreed to
purchase (1) the Management Sellers' interests in the HealthFirst Management
Agreements and all books, records, computer hardware and software and other
assets of HealthFirst and/or Sellers associated with the Surgery Centers or used
in performing the HealthFirst Management Agreements, including without
limitation the tangible personal property listed in Schedule 3 attached hereto
(collectively, the "HealthFirst Transferred Assets"), and (2) all of the
interests in the Partnerships held by Forest Edge and Oak Mount (the
"Partnership Sellers") in DeSoto, Metroplex and Irving.

            G. The Partnership Sellers will grant Buyer an option to purchase
all of their interests in Fort Worth, and VVSC will grant Buyer an option to
Purchase all of the interest in DSP indirectly owned by the Principals and
Kathleen Disney (and the proceeds of such sale by VVSC shall be used to redeem
the shares in VVSC held by the Principals and Kathleen Disney).

                                       2
<PAGE>

            H. The percentage interest in the Partnerships owned by each
Partnership Seller is set forth in Schedule 1 attached hereto. The Partnership
interests owned by the Partnership Sellers in the Initial Partnerships and all
of their respective right, title and interest in and to the Initial
Partnerships, including all rights and interests under the respective
Partnership Agreements and all related assets (the "Transferred Partnership
Interests"), together with the "HealthFirst Transferred Assets," are hereinafter
collectively referred to as The "Transferred Assets."

            I. The Transferred Assets shall not include (1) any cash or cash
equivalent assets of any Seller, (2) any interest in Texas Health Ventures
Group, L.L.C., a Texas limited liability company ("THVG"), (3) assets of
HealthFirst or any Seller used exclusively in connection with the business of
THVG or (4) any of the other assets listed in Schedule 4 attached hereto
(collectively, the "Excluded Assets")

            THEREFORE, the parties hereto agree as follows:

                               A G R E E M E N T

            1. Purchase and Sale of Transferred Assets. Subject to the terms and
conditions of this Agreement, Sellers agree to sell, transfer and deliver the
Transferred Assets to Buyer, and Buyer agrees to purchase and accept their
respective Transferred Assets from Sellers, at the Closing on the Closing Date
(as those terms are defined in Section 2). In full consideration for the sale,
transfer and delivery to Buyer of the Transferred Assets at the Closing:

                  (a) Closing Date Payment. At the Closing, Buyer shall pay to
Sellers cash in the aggregate amount of $8,001,047, subject to post-Closing
adjustment in accordance with Section 8(b). Such Closing Date payment shall be
allocated among Sellers as provided in Schedule 5 attached hereto, which shall
be prepared by Principals and submitted to Buyer at least three business days
prior to the Closing Date and, if accepted by Buyer, shall be attached hereto
and shall be used for purposes of this Section 1(a). (Schedule 5 shall also
include the information described in Sections 1(d)(i), 1(f) and 8(e)(iv)
hereof.)

                  (b) Intentionally omitted.

                  (c) Contingent Post-Closing Payments. In addition to the
payments to be made pursuant to Sections 1(a) and (b) above and as additional
consideration for the sale of the Transferred Partnership Interests, Buyer shall
pay to the Partnership Sellers, in the aggregate, the following additional
amounts:

                        (i) An amount equal to four times the excess (if any) of
            the aggregate net earnings before interest, taxes, depreciation and
            amortization allocated to Buyer by the Initial Partnerships on the
            Transferred Partnership Interests (not including any management fees
            earned by Buyer from the Partnerships) (the total of which is
            hereinafter collectively referred to as the "EBITDA"), for the 12
            month period beginning on the Effective Date ("Year One") over (B)
            $620,900 (the "Base Amount"); plus

                                       3
<PAGE>

                        (ii) Three times the amount by which EBITDA for the 12
            month period beginning on the first anniversary of the Effective
            Date ("Year Two") exceeds the greater of the Base Amount or the
            EBITDA for Year One; plus

                        (iii) Three times the amount by which EBITDA for the 12
            month period beginning on the second anniversary of the Effective
            Date ("Year Three") exceeds the greatest of (A) the Base Amount, (B)
            the EBITDA for Year Two or (C) the EBITDA for Year One;

provided, however, that the total amount payable pursuant to this Section 1(c)
shall not exceed 25% of the sum of (x) the Closing Date payments to the
Partnership Sellers pursuant to Section 1(a) and (y) plus or minus any
adjustment to such payments pursuant to Section 8(b).

            For purposes of this Section 1(c), EBITDA shall be determined in
accordance with generally accepted accounting principles in effect on the date
of this Agreement applied in a manner consistent with the calculation of the
Base Amount ("GAAP"); provided, however, that (1) extraordinary items (as
determined in accordance with GAAP) shall be excluded, (2) if the EBITDA for
Year One or Year Two is a negative amount, such negative amount shall carry over
and be treated as an expense in the next 12 month period, (3) Buyer shall
allocate the expenses of the Center Support Organization acquired by Buyer from
the Management Sellers substantially in the same manner as HealthFirst has
heretofore allocated such expenses to the Surgery Centers, which Center Support
Organization shall include Buyer's regional surgery center management personnel
(other than the Principals) that have responsibility for the Surgery Centers
(who initially will be Carolyn Exley) and other personnel whose services are
devoted to the Surgery Centers (provided that, in the event Buyer otherwise
significantly modifies the "Center Support Organization" structure used by
HealthFirst, the manner of allocating the equivalent expenses in the new format
shall be agreed upon in good faith by the Principals and Buyer, but such costs
shall in any event be allocated only for the portion of such time that is
directly spent on the Surgery Centers), (4) each Surgery Center shall be treated
as a separate accounting unit of Buyer that is unaffected by acquisitions or
sales by Buyer that do not relate to the Surgery Centers, (5) the calculation
shall not include reserves or contingencies for expenses which any party has an
indemnification obligation to the other party under this Agreement, (6) there
shall be no charge for professional services (including legal expenses) incurred
by Buyer in connection with this Agreement or the transactions provided for
herein, including without limitation any costs of obtaining funding to pay the
purchase price for the Transferred Assets, (7) the calculation shall not include
any adverse consequence of Buyer refinancing any Partnership debt (other than
any such refinancing that is done at the time of, or within six months prior to,
the maturity date of any such debt) and (8) if a Surgery Center does not have
sufficient cash to operate in accordance with past practices, and if Buyer
elects not to provide such funds itself, then Sellers or the Principals shall be
entitled to provide loans to the Partnership that owns such Surgery Center to
cover such cash shortfalls, which loans shall be made on reasonable terms that
are acceptable to Sellers or the Principals (as the case may be), including a
provision that liability for such loan shall be limited to the assets of the
Partnership - i.e., there shall no recourse to the general partner of the
Partnership with respect to any such loan. The Principals shall have access to
appropriate books and records, and (at their expense) the right to review and
audit the financial statements, relating to the Surgery Centers and/or the
Partnerships.

                                       4

            The calculation of EBITDA for each of Year One, Two and Three, and
of the Partnership EBITDA for each "Base Year" pursuant to Section 8(e)(ii)(A),
and the EBITDA calculations pursuant to Sections 8(f)(ii) or 8(g)(ii), shall
initially be made by Buyer and a statement (the "Statement") reflecting each
such calculation in reasonable detail shall be provided to the Principals within
60 days after the end of the respective periods for which such calculations are
to be made. If neither of the Principals notifies Buyer of any objection to a
Statement within 60 days after the receipt of such Statement, the Statement
shall be deemed accepted on behalf of each of the Sellers. If either Principal
provides notice of any objection to a Statement (which notice shall include a
description of such objections) within such 60 day period, the Principals and
Buyer shall use their best efforts to resolve any differences relating to the
Statement within 15 days after such objection is delivered to Buyer. If the
disagreement is not resolved by that date, however, either Buyer or any
Principal may submit the matter for a binding determination of the calculation
of EBITDA or Partnership EBITDA (as the case may be) set forth in the Statement
to KPMG Peat Marwick LLP or another nationally recognized accounting firm
approved by Buyer and the Principals, which firm shall act as an expert and not
as an arbitrator in making such determination; the fees of such accounting firm,
which shall be billed separately and independently from any other services
provided by such firm, shall be paid by Buyer if the final determination of the
amount payable pursuant to subsection (i), (ii) or (iii) above or Section 8(e),
8(f) or (g), as the case may be, based upon such Statement is at least 10% over
the amount shown to be payable by the Statement as initially submitted by Buyer
and, otherwise, such expenses shall be paid by the Principals as a reduction of
any consideration then due pursuant to this Section 1(c) or Section 8(e), 8(f)
or (g) or if no such consideration is then due or the amount of such
consideration is less than the amount of such fees, such shortfall shall be paid
by Principals.

            Each Statement delivered by Buyer pursuant to subsection (i), (ii)
or (iii) or Section 8(e), 8(f) or (g), as the case may be, shall be accompanied
by payment of the amount (if any) that is shown to be due based upon such
Statement. In the event of any dispute regarding a Statement, the balance (if
any) that is due as a result of the resolution of such dispute shall be paid by
Buyer within five business days after a final determination of the EBITDA in
accordance with the foregoing procedures.

            Any payments made pursuant to this Section 1(c) shall be paid in
cash and stock as provided in Section 1(d) and shall be allocated one-half to
each of the Partnership Sellers.

                  (d) Form of Consideration. The consideration to be delivered
by Buyer to Sellers pursuant to Sections 1(a) and 1(c) hereof shall be paid as
follows:

                        (i) The consideration due to Sellers pursuant to Section
            1(a) shall be paid by Buyer's check or, if a Seller so requests and
            provides appropriate instructions at least three business day prior
            to the Closing Date, by wire transfer of immediately available
            funds. The allocation of such cash payment among Sellers shall be as
            set forth in Schedule 5 to be attached hereto.

                        (ii) Each payment obligation that arises pursuant to
            Section 1(c) shall be made either (A) all in cash by Buyer's check
            or, in the event the recipient of such payment provides wire
            transfer instructions at least three

                                       5
<PAGE>

            business days prior to the date such payment is to be made, by wire
            transfer of immediately available funds, or (B) if the party that is
            to receive such payment so elects by giving written notice to Buyer
            at least 10 business days prior to the date such payment is to be
            made, at least 80% of such payment shall be made in cash (as
            described in clause (A) above) and up to 20% of such amount shall be
            payable by the issuance of shares of Buyer's Class A Common Stock,
            par value $0.01 per share (the "Buyer Stock"), valued at the greater
            of $4.00 per share or the fair market value per share of Buyer Stock
            at the time such payment is due, as determined in good faith by the
            Board of Directors of Buyer; provided, however, that in the event
            Buyer is required to make any such payment in cash but is unable to
            do so (as a result of not having either sufficient cash or cash
            equivalent assets or the ability to draw on available lines of
            credit in order to obtain such cash), the following shall apply to
            the extent of such cash shortfall:

                  (x) If the Buyer Stock is then registered under the Securities
      Exchange Act of 1934, and if Buyer delivers shares of Buyer Stock that are
      registered and freely tradable under the Securities Act of 1933, then
      Buyer shall be entitled to make such payment in Buyer Stock, valued at the
      average closing sales price on the primary stock exchange (or NASDAQ) on
      which the Buyer Stock is then traded over the ten trading days ended three
      business days prior to the date that such Buyer Stock is issued;

                  (y) If the Buyer Stock is then registered under the Securities
      Exchange Act of 1934, but Buyer does not deliver shares of Buyer Stock
      that are registered and freely tradable under the Securities Act of 1933,
      then Buyer shall be entitled to make such payment through the issuance of
      shares of Buyer Stock valued at 80% of the average closing sales price on
      the primary stock exchange (or NASDAQ) on which such shares are then
      traded over the ten trading days ended three business days prior to the
      issuance of such shares; and

                  (z) If the Buyer Stock is not then registered under the
      Securities Exchange Act of 1934, Buyer shall be entitled to make such
      payment in shares of Buyer Stock valued at the fair market value per share
      of Buyer Stock at the time such payment is due, (i) as determined by the
      Board of Directors of Buyer in good faith based upon one or more issuances
      of Buyer Stock in arm's length transactions within six months prior to the
      date of the issuance pursuant hereto, or (ii) if no such issuance has
      occurred within said six month period, as agreed upon by Buyer and the
      Principals, but if Buyer and the Principals are not able to agree on such
      fair market value, then they shall agree upon an independent appraiser to
      appraise the Buyer Stock or, if they cannot agree on an appraiser, they
      shall each select an independent appraiser who shall appraise the Buyer
      Stock. If the two appraisers agree on an appraised price, such price shall
      be the fair market value of the Buyer Stock for purposes hereof. If the
      two appraisers cannot so agree, then the average of the two appraisals
      shall govern if the higher appraisal is no greater than 120% of the lower
      appraisal and, if there is greater than such a 20% variance, the two
      appraisers shall select a third appraiser who shall determine the final
      fair market value of Buyer Stock for purposes of such payment. The dollar
      amount of any payment that is made pursuant to this subsection (z) shall
      be increased to 125% of the amount that would otherwise be payable
      pursuant to this subsection (ii).

<PAGE>

                        (iii) Anything herein to the contrary notwithstanding,
            the right to receive shares of Buyer Stock hereunder shall apply
            only to those Sellers that are owned 100% by the Principals and/or
            their immediate families (or trusts for their benefit), except that
            VVSC shall be entitled to receive Buyer Stock only if there is a
            binding agreement among the Principals and VVSC to concurrently
            retransfer such shares of Buyer Stock to the Principals and Kathleen
            Disney in connection with the redemption of their shares in VVSC.

                        (iv) Each Principal and Seller acknowledges and agrees
            that any shares of Buyer Stock to be issued pursuant to this
            Agreement (other than shares issued pursuant to subsection (ii)(ii)
            (x) above) (A) will be "restricted stock" under federal and state
            securities laws, (B) are being acquired for investment purposes only
            and without any view toward the resale or distribution thereof
            (other than a transfer by any Seller to the Principals) and (C)
            shall be subject to the provisions of Buyer's Amended and Restated
            Registration Rights Agreements and its Amended and Restated
            Stockholders Agreement pursuant to the Amendments to be entered into
            in accordance with Section 6 (k).

                  (e) Assumption of Obligations. Buyer shall assume and shall
perform and discharge (i) the obligations of Sellers set forth on Schedule 5A
attached hereto, (ii) the liabilities and obligations of the Management Sellers

Except for the liabilities and obligations described in this Section 1(e), and

            3. Representations and Warranties by HealthFirst, Sellers and
Principals. Except as specifically set forth in Schedule 6 attached hereto,
HealthFirst and the Principals, jointly and severally, and each Seller (as to
its own Transferred Assets, contracts, liabilities and other operations),
represent and warrant to Buyer as follows:

                  (a) Organization, Standing, etc. The information set forth in
Schedule 1 and the information relating to Sellers, the Former Owners and
Principals set forth in Recitals A and B is accurate and complete with respect
to the matters purported to be covered thereby. HealthFirst and HFMFW each is a
duly and validly organized and existing limited liability company, and each
other Former Owner is a duly and validly organized and existing corporation, in
good standing under the laws of the State of Texas, with full power and
authority to carry on its business as presently conducted. Each Seller is a duly
and validly organized and existing limited liability partnership or limited
partnership (as the case may be) in good standing under the laws of the State of
Texas and has full power and authority to carry on its business as presently
conducted. The Partnerships have no direct or indirect interest of any kind in
any other corporation, partnership, association or business. Each of the
Partnerships is duly organized and validly existing under the laws of the State
of Texas, with all requisite power and authority to carry on its business as
presently conducted. None of the Partnerships has conducted any business or
engaged in any activity outside of the State of Texas, except where such conduct
or activities will not have a material adverse effect on the business,
properties, operations, condition, financial or otherwise, or results of
operations of the Partnerships taken as a whole (a "Material Adverse Effect").

                  (b) Due Authorization. The execution, delivery and performance
of this Agreement by HealthFirst and Sellers have been duly and validly approved
by the members and managers of HealthFirst and by the partners of each Seller
and no further action is necessary to make this Agreement valid and binding upon
HealthFirst and Sellers in accordance with its terms.

                  (c) Compliance with Instruments and Agreements. The
transactions whereby any or all of the Transferred Assets were contributed or
otherwise transferred by HealthFirst and the Former Owners to Sellers: (i) were
effective to transfer good title to the Transferred Assets to Sellers; (ii) were
conducted in compliance with the charter documents (including without limitation
shareholders agreements, regulations or operating agreements) of HealthFirst and
the Former Owners; (iii) were approved by all requisite action of the owners and
the governing bodies of HealthFirst and each Former Owner; (iv) did not result
in any breach of any term or provision of, or constitute a default under, any
order, judgment, injunction, decree, indenture, mortgage, lease, lien, agreement
or other instrument to which HealthFirst or any Former Owner is a party or by
which any of the Transferred Assets is bound; and (v) were in compliance with
all applicable laws and did not constitute a "fraudulent conveyance" under state
law or federal bankruptcy law. The performance of this Agreement and the
consummation of the transactions contemplated hereby will not result in any
breach or violation of any of the terms or provisions of, or constitute a
default under, (i) the articles of organization, regulations or operating
agreement of either HealthFirst or HFMFW, (ii) the partnership certificate or
partnership agreement or any Seller, (iii) articles of incorporation, bylaws or
any shareholders agreement of VVSC or any Former Owner, (iv) any Partnership
Agreement, (v) any statute, order, rule or regulation of any court or
governmental agency or

                                       8
<PAGE>

body having jurisdiction over HealthFirst or any Seller, Former Owner or
Partnership or (vi) assuming that the required consents referred to in Schedule
11 attached hereto are obtained at or prior to the Closing Date, any agreement,
instrument or commitment to which HealthFirst or any Principal, Seller, Former
Owner or Partnership is a party, by which any of them is bound or to which any
of their property is subject.

                  (d) Capitalization and Indebtedness for Borrowed Moneys.

                        (i) Capitalization. Schedule 7 attached hereto is a true
            and complete list of the names, types of equity interests owned and
            percentage interests held by each person or entity who has any legal
            or beneficial ownership interest in each of the Partnerships and in
            VVSC. HealthFirst has delivered to Buyer true and complete copies of
            the articles of organization, regulations, partnership certificates,
            partnership agreements, articles of incorporation and bylaws (as
            applicable) of HealthFirst and each of the Former Owners and
            Sellers, each shareholders agreement among the shareholders of any
            Seller and each of the Partnership Agreements and certificates of
            partnership of each of the Partnerships, which certificates of
            partnership have been filed with all appropriate state and local
            government authorities.

                        (ii) Indebtedness for Borrowed Moneys. The Partnerships
            have no outstanding indebtedness for borrowed moneys, indebtedness
            to any Seller, HealthFirst, Former Owner or Principal, long term
            leases or other obligations required by GAAP to be shown on a
            balance sheet as long term liabilities (collectively,
            "Indebtedness"), except for the Indebtedness described in Schedule
            8A attached hereto. True and complete copies of every instrument,
            agreement and other document relating to any such Indebtedness have
            been delivered to Buyer. Immediately following the Closing, no
            Partnership will be indebted to or have any obligation to
            HealthFirst or any Seller, Principal or Former Owner, or any partner
            or shareholder of any Seller or Former Owner or any of their
            respective relatives or affiliates other than the Indebtedness
            described in Schedule 8k attached hereto.

                        (iii) Options or Rights. Except for the rights of first
            refusal provided for in the Partnership Agreements, there are no
            outstanding agreements, rights, subscriptions, options, warrants,
            convertible securities, commitments, arrangements or understandings
            of any character under which any of the Partnerships or any Seller
            is or may be obligated to issue or purchase any interest in any of
            the Partnerships or any Seller.

                  (e) Financial Statements. Attached hereto as Schedule 8 are
true and complete copies of unaudited balance sheets (the "Balance Sheets") of
HealthFirst and each of the Partnerships as of July 31, 1998 (the "Balance Sheet
Date"). HealthFirst has also provided to Buyer unaudited statements of
operations for the fiscal year ended December 31, 1997 and the seven month
period ended on the Balance Sheet Date for HealthFirst and each of the
Partnerships and all other financial information requested by Buyer and its
professional advisors, all of which has been reviewed by Buyer. The Balance
Sheets and such statements of operations

                                       9
<PAGE>

(i) are in accordance with the books and records of HealthFirst and the
respective Partnerships to which they relate, (ii) fairly present the financial
condition of HealthFirst and the Partnerships to which they relate at the
Balance Sheet Date and the results of operations for the entities and periods
therein specified and (iii) except as stated in the notes to such financial
statements, have been prepared in accordance with GAAP consistently applied
(excluding footnotes and normal year end adjustments). Except for the
liabilities reflected in the Balance Sheets, the documents described in
Schedules 8A and 9 and other obligations incurred in the ordinary course of
business since the Balance Sheet Date (none of which will have a Material
Adverse Effect), none of the Partnerships has or is subject to any liability of
any nature, whether accrued, absolute, contingent or otherwise. Each Partnership
is and as of the Closing Date will be current in all payment obligations to
which it is subject, other than payment obligations to HealthFirst or a Seller,
Former Owner or Principal described in Schedule 8A.

                  (f) Title to Transferred Assets. Each Partnership Seller has
good and marketable title to the interest in the Partnerships identified in
Schedule 1, free and clear of all liens, claims, encumbrances and restrictions,
legal or equitable, of every kind, except for restrictions on transfer imposed
by federal or state securities laws or the applicable Partnership Agreement of
the Associated Partnership. Each Management Seller has good and marketable title
to the HealthFirst Transferred Assets, free and clear of all liens, claims,
encumbrances and restrictions, legal or equitable, of every kind, except for
restrictions on transfer identified in Schedule 11 that are set forth in any
HealthFirst Management Agreement. Each Seller has full and unrestricted legal
right, power and authority to sell, assign and transfer the Transferred Assets
without obtaining the consent or approval of any other person, entity or
governmental authority (other than the consents described in Schedule 9), and
the delivery of the Transferred Assets to Buyer pursuant to this Agreement will
transfer valid title thereto, free and clear of all liens, encumbrances, claims
and restrictions of every kind, except for restrictions on transferability
imposed by federal and state securities laws or said partnership agreements.

                  (g) Partnerships' Assets. Each Partnership has good and
marketable title to all of the properties and assets used in its business
(including leasehold interests as to such assets that are leased by a
Partnership), subject to no mortgage, pledge, lien, security interest,
encumbrance or other charge, other than (i) the interests of equipment lessors
with respect to leased equipment under the equipment leases identified in
Schedule 9, (ii) liens in favor of lenders with respect to the loans reflected
on the Balance Sheets, (iii) liens for taxes not yet due or being contested in
good faith, (iv) liens created pursuant to the contracts listed on Schedule 9
and (v) other liens that will not have a Material Adverse Effect. The assets
owned or leased by the Partnerships constitute all of the assets currently in
existence which are being used in the Surgery Centers.

                  (h) Non-Competition Covenants. Except for the noncompetition
covenant contained herein and in each Principal's Employment Agreement entered
into pursuant to Sections 6(j)and 7(e), neither HealthFirst nor any of the
Sellers or the Partnerships is subject to any non-competition covenant or other
similar agreement restricting its ability to engage in competitive businesses.
Following the Closing, Buyer and its affiliates will not be subject to any such
non-competition covenant or restrictive agreement by virtue of Buyer's
acquisition of the Transferred Assets.

                                       10

                  (i) Accounts Receivable. True and complete lists of all
outstanding accounts receivable of the Partnerships as of the Balance Sheet Date
(including agings) have been delivered to Buyer. All of the accounts receivable
held by any Partnership are valid and enforceable claims and are not subject to
any defenses, offsets, claims or counterclaims. Although the Principals know of
no reason why such accounts will not be collected on a timely basis, no
representation is made hereby that such accounts will be collected and,
notwithstanding any of the provisions of this Agreement, no party hereto
guarantees collection of any such accounts receivable. The allowances for
doubtful accounts and contractual adjustments reflected in the Balance Sheets
are based upon historic collection activities of the Partnerships and have been
determined in accordance with GAAP.

                  (j) Real Property Leases. HealthFirst has provided to Buyer
true and complete copies of each of the Real Property Leases Except as shown in
Schedule 2, none of the lessees under any of the Real Property Leases have
assigned, subleased or conveyed any interest in any of the Real Property Leases
or the premises covered thereby. Each of the Real Property Leases is in full
force and effect and constitutes the valid and binding agreement of the tenant
and (to the best knowledge of the Principals) the landlord named therein. No
Partnership or (to the best knowledge of the Principals) other party is in
default under any of the Real Property Leases and no event or condition has
occurred or exists which, with the passage of time, the giving of notice or
both, would cause either a Partnership or (to the best knowledge of the
Principals) any other party under any Real Property Lease to be in default
thereunder,

                  (k) Material Contracts. HealthFirst has delivered to Buyer an
accurate list and brief description (attached hereto as Schedule 9) as of the
date hereof of all material contracts, leases (other than the Real Property
Leases) and instruments to which any of the Partnerships is a party or by which
it or any of its assets are bound. For purposes hereof, the term "material
contracts" shall mean the following: (i) all equipment leases where the
aggregate rent required to be paid on or after the Effective Date under the
terms of such lease (excluding rent payments that could be avoided by exercising
cancellation or non-renewal rights) is at least $10,000; (ii) all executory
purchase agreements relating to the purchase of equipment, supplies or other
goods where the non-cancellable amount that is payable after the Effective Date
is at least $10,000; (iii) all agreements to which any Partnership (on the one
hand) and any partner of any Partnership, any partner or shareholder of any
Seller or Former Owner or any physician or any member of the medical staff of
any of the Surgery Centers, or any of their relatives or affiliates (on the
other hand), is a party; (iv) all employment and consulting agreements; (v) all
agreements with health maintenance organizations, insurance companies, provider
organizations and other managed care entities, or other contract whereunder any
Surgery Center is committed to provide Surgery Center services; and (vi) all
other agreements and commitments in which the non-cancellable financial
obligation of the Partnership as of the Effective Date is at least $25,000. Also
included in Schedule 9 is a list of all material contracts to which HealthFirst
or any Seller is a party, including without limitation any commitment or
proposal to acquire, develop or affiliate with any ambulatory surgery center or
any health facility (but not including debt instruments not involving a
Partnership). HealthFirst has delivered to Buyer or its counsel true and
complete copies of documents and instruments (if any) described in Schedules 2
and 9. To the best knowledge of Principals, all of the agreements, contracts,
leases and instruments listed in Schedule 9 are valid and binding. Neither
HealthFirst nor any Seller, Former Owner or Partnership has breached and, to the
knowledge of the Principals, no other party thereto has

                                       11
<PAGE>

breached any provision of, or is in default under the terms of, and there are no
facts or circumstances which would reasonably indicate that HealthFirst or any
Seller, Former Owner or Partnership will or may be in such breach or default
under, any such agreement, contract, lease or instrument, which invalidity,
breach or default could have a Material Adverse Effect.

                  (l) Tax Returns and Audits. HealthFirst and the Partnerships
have accurately prepared and filed all federal, state and local income,
withholding, sales and property tax returns and all information statements
required to be filed prior to the date of this Agreement (subject to any
extensions available without penalty). True and complete copies of each of the
two most recent of each such return or statement have been provided to Buyer.
All federal, state and local taxes required to be paid or withheld with respect
to the periods covered by such returns and statements have been paid or
withheld. Except for Buyer's share of federal and state income tax liabilities
with respect to income for the Partnership's tax years ending on December 31,
1998 (as provided in Section 8(i) below), Buyer shall not be liable for any tax
obligation of HealthFirst or any Seller, Former Owner, Principal or Partnership
resulting from the business of HealthFirst or any Seller, Former Owner or
Partnership prior to the Effective Date. No tax liability will be incurred by
any of the Partnerships as a result of the transactions contemplated by this
Agreement. Neither HealthFirst nor any Seller or Partnership has been delinquent
in any withholding of employee taxes or in the payment of any tax, assessment or
governmental charge. No Partnership has ever had any tax deficiency proposed or
assessed against it and has not executed any waiver of any statute of
limitations on the assessment or collection of any tax. Neither the federal
income tax returns nor the state income or franchise tax returns (if any) of
HealthFirst or any Partnership have ever been audited by any governmental
authority.

                  (m) Litigation and Proceedings. Except as described in
Schedule 10, there are no legal claims, actions, suits, medical staff disputes,
arbitrations or other legal, administrative or governmental proceedings pending
or, to the knowledge of the Principals, threatened against any Partnership or
any properties, assets or business of any Partnership, and to the Principal's
knowledge no facts exist which would form the basis for any such action or which
have been or should be reported under any professional liability insurance
policy covering any Surgery Center. Neither HealthFirst nor any Seller, Former
Owner or Partnership is involved in any material dispute with any shareholder or
partner of a Seller or any partner of a Partnership. No Seller, Former Owner or
Partnership is in default with respect to any judgment, order or decree of any
court, governmental agency or instrumentality. Schedule 10 contains a complete
and accurate description of the status of any matter covered thereby and Sellers
and the Partnerships carry adequate insurance to cover the cost, expenses and
damages of each of the matters described therein. Except for normal collection
efforts relating to accounts receivable, none of the Partnerships is engaged in
any legal action to recover money due to or damages sustained by any of them.

                  (n) Compliance with Law and Instruments. The business and
operations of HealthFirst and each Seller and Partnership have been and are
being conducted in compliance in all material respects with all applicable laws,
rules and regulations and licensing requirements of all authorities, the
violation of which could have a Material Adverse Effect HealthFirst and each
Principal, Former Owner, Seller and Partnership has complied with all applicable
federal and state securities laws in connection with the sale or resale of any
equity

                                       12
<PAGE>

interest in any Partnership. Each of the Surgery Centers meets (i) the
conditions for participation in the Medicare program and (ii) the requirements
for accreditation of ambulatory surgical centers of, and each Surgery Center is
accredited by, the Joint Commission on Accreditation of Healthcare
Organizations. No certificates of need were required for the construction or
operation of the Surgery Centers. Except for the consents and notice
requirements described in Schedule 11, the execution and delivery of this
Agreement and the consummation of the transactions provided herein will not
require any governmental consent, review or other process or the consent of any
party to any material lease, contract, agreement or instrument to which
HealthFirst or any of the Partnerships or Sellers is a party or by which any of
their respective assets is subject. Each of the Surgery Centers is authorized to
receive (and has received) payments for procedures covered by the Medicare
program. Neither the U.S. Department of Health and Human Services nor any state
agency has conducted, or has given HealthFirst or any Seller, Former Owner,
Principal or Partnership written notice that it intends to conduct, any audit or
other review of any Surgery Center's participation in the Medicare or Medicaid
programs (other than routine annual surveys, reviews and audits), and no such
audit or review would result in any material liability by HealthFirst or any
Seller, Former Owner or Partnership for any reimbursement, penalty or interest
with respect to payments received by HealthFirst or any Seller, Former Owner or
Partnership thereunder. The Principals do not know of any reason why the
Partnerships will not or may not be able to continue their respective
businesses, as presently conducted, after the Closing.

                  (o) Absence of Specified Changes. Except for the transactions
and agreements provided for herein, since the Balance Sheet Date there have not
been: (i) any transactions by any Partnership except in the ordinary course of
business as conducted on the Balance Sheet Date; (ii) any capital expenditure by
any Partnership exceeding $25,000; (iii) any cancellation of any debt or claim
or waiver of any right of substantial value; (iv) any material change in the
quantity or quality of the equipment, surgical instruments and supplies of any
of the Surgery Centers, except for changes due to ordinary wear and tear and
changes in quantities of supplies in the ordinary course of business; (v) any
destruction, damage to or loss of any material asset of any of the Partnerships,
whether or not covered by insurance; (vi) the creation or imposition of any
mortgage, pledge or other encumbrance on any asset of any Partnership, other
than purchase money liens on newly acquired assets; (vii) any increase in
salaries or benefits to employees or independent contractors of any Partnership
other than annual increases implemented in accordance with the past practices of
such Partnership; (viii) any material amendment to any of the material contracts
listed in Schedule 9, other than in the ordinary course of business of any
Partnership; (ix) any material adverse change in the financial condition,
business or prospects of any Partnership; (x) any sale, transfer or disposition
of any equipment that is material to such Partnership; or (xi) any agreement by
HealthFirst or any Seller, Former Owner or Partnership to do any of the things
described in this subsection (o).

                  (p) Insurance Policies. Each Partnership maintains in full
force and effect, and has maintained at all times since its inception, insurance
coverage on its assets, properties, operations and personnel in such amounts and
against such risks and losses as are described in Schedule 12 attached hereto,
which includes a brief description of all outstanding insurance policies in
effect as of the date hereof covering HealthFirst or any of the Partnerships or
any of their respective properties, employees, partners or businesses.
HealthFirst has provided to Buyer complete and accurate copies of all insurance
policies or certificates of insurance under

                                       13

which any of the Partnerships is insured, including the coverage limits and
deductibles applicable thereto. HealthFirst, Sellers, the Former Owners and the
Partnerships are in compliance in all material respects with all of their
respective obligations under such insurance policies. All such policies are now
and will be through the Closing Date in full force and effect.

                  (q) Compensation and Benefits. Schedule 13 is an accurate and
complete list setting forth the names, salaries or other remuneration, bonuses
and employee benefits (including all severance benefits) of all current
employees whose annual base salary is in excess of $30,000 and of all
consultants (other than accountants and attorneys) of HealthFirst, Sellers and
each of the Partnerships. Neither HealthFirst nor any Seller or Partnership has
any collective bargaining agreement with any labor union and is not currently
negotiating with a labor union and no employee of HealthFirst or any Seller or
Partnership or has ever petitioned for a representation election. No employee of
HealthFirst or any Partnership, Former Owner or Seller has ever filed with any
governmental authority any claim asserting sexual harassment, age, racial or
other employment discrimination or violation of OSHA or any similar state law
against HealthFirst or any Principal, Seller, Former Owner or Partnership.
Neither HealthFirst nor any Seller, Former Owner or Partnership has received any
"right to sue" letter relating to any of their respective employees or former
employees from any federal or state agency.

                  (r) Retirement Plans. Except as set forth in Schedule 13, none
of the Partnerships has ever maintained or participated in any pension, profit
sharing or other retirement plan, nor have they ever participated in, any
multi-employer plan as defined in Section 4001(a) (3) of the Employee Retirement
Income Security Act of 1974 ("ERISA") . Neither Buyer nor any Partnership will
incur any obligation or liability under or relating to the Plan as a result of
the transactions contemplated by this Agreement, or otherwise.

                  (s) No Brokers or Finders. As a result of any act or failure
to act by HealthFirst, any Seller, any Former Owner, any Principal or any
Partnership, no person or entity has, or as a result of the transactions
contemplated hereby will have, any right, interest or valid claim against or
upon Buyer or any Partnership for any commission, fee or other compensation as a
broker, finder or any similar capacity.

                  (t) Contracts with Affiliates. Except as described in Schedule
9, there are no contracts, agreements, understandings or other relationships
between any of the Partnerships, on the one hand, and any person or entity that
owns any equity interest in any Seller or Partnership, on the other hand, except
as expressly described or provided for in this Agreement.

                  (u) The Real Property.

                        (i) Neither HealthFirst nor any Seller, Former Owner,
            Principal or Partnership has received written notice of either a
            violation of any applicable ordinance or other law, order,
            regulation or requirement, or any condemnation, lien, assessment or
            the like, relating to any part of the Real Property or the operation
            thereof and, to the best knowledge of the Principals, there is not
            presently contemplated or proposed any condemnation or similar

            Property and its operation are in compliance with all applicable
            zoning ordinances (including without limitation parking
            requirements) and building codes, and the consummation of the
            transactions contemplated herein will not result in the termination
            of any current zoning variance;

                        (iii) The Real Property and all buildings, improvements
            and fixtures thereon or therein, and all parts thereof and
            appurtenances thereto, including without limitation the plumbing,
            electrical, mechanical, heating, ventilation and air conditioning
            systems, are in good operating condition and in a reasonable state
            of maintenance and repair, except for normal wear and tear;

of satisfactory due diligence by Buyer and to the receipt of all necessary

necessary or appropriate by the Principals, Baylor Health Care System shall have
acknowledged that the execution of such binding agreement shall not breach any
obligations of HealthFirst, Disney THVG, L.L.P or Bingham THVG, L.L.P. with
respect to THVG or cause any rights of first refusal or other similar provisions
to be applicable with respect to their respective interests in THVG.

                  (m) Insurance Coverage for Pre-Effective Date Malpractice
Claims. Each Partnership shall have obtained (at its expense) "tail" or "prior

            8. Post-Closing Covenants.

                  (a) Indemnification.

                        (i) Buyer covenants and agrees that it will indemnify
            and hold HealthFirst, Sellers and Principals, and their respective
            successors and assigns and their respective officers, directors,
            employees, stockholders and agents at all times harmless from and
            against any loss, liability, damage and expense (including
            reasonable attorneys' fees and other costs of defense) caused by or
            arising out of or in connection with (A) any liability or obligation
            expressly assumed by Buyer pursuant to Section 1(e) or (B) any
            misrepresentation, breach of warranty or nonfulfillment of any
            agreement on the part of Buyer under this Agreement. Without
            limiting the generality of the foregoing, HealthFirst, Sellers and
            Principals shall have the right to be put in the same financial
            position as they would have been in had each of the representations
            and warranties of Buyer been true and correct and had each of the
            covenants of Buyer been performed in full.

                        (ii) HealthFirst, Sellers and the Principals jointly and
            severally covenant and agree that they will indemnify and hold Buyer
            and its successors and assigns and their respective officers,
            directors, employees, stockholders and agents at all times harmless
            from and against any loss, liability, damage and expense (including
            reasonable attorneys' fees and other costs of defense) caused by or
            arising out of or in connection with (A) any liability of
            HealthFirst or any Seller or Former Owner not expressly assumed by
            Buyer pursuant to Section 1(e) hereof, (B) any dispute between or
            among any partner or former partner of a Partnership (on the one
            hand) and HealthFirst and/or any Seller, Former Owner, Principal
            and/or Partnership (on the other hand) relating to any obligation
            that was to be performed, or action that was taken, on or before the
            Effective Date or any misrepresentation, breach of warranty or
            nonfulfillment of any agreement on the part of HealthFirst or any
            Seller or Principal under this Agreement, provided, however, that
            Buyer shall not be entitled to make any claim for indemnification
            pursuant to clause (C) above (I) with respect to any such breach of
            representations and warranties unless and until the monetary value
            of all such breaches (on a cumulative basis) exceeds $50,000, in
            which event HealthFirst, Sellers and the Principals shall be liable
            for the full monetary value of all such breaches (including the
            initial $50,000), (II) at any time after the second anniversary of
            the Closing Date, except for (x) claims asserted in writing pursuant
            to this Section 8(a) (ii) prior to such second anniversary, (y)
            claims made with respect to any

                                       25
<PAGE>

            breach of Section 3(a), (b), (f), (g), (h), (l), (s), (x) or (bb) or
            Section 8(c), (d), (e), (f), (g), (i) or (l) hereof and (z) claims
            relating to any liability of HealthFirst or any Seller or Former
            Owner not assumed by Buyer, which shall remain the obligation of
            HealthFirst, Sellers, the Former Owners and the Principals at all
            times, or (III) that, when aggregated with all other claims made
            pursuant to clause (C), would cause the total liability of
            HealthFirst, Sellers and Principals thereunder to exceed $5,000,000.
            Notwithstanding the foregoing, clauses (I), (II) and (III) above
            shall not apply to Section 8(n), which shall be an independent
            covenant that is not subject to any such limitations. In addition,
            with respect to any claim under this subsection (ii) that arises out
            of a liability or obligation of a Partnership, the indemnity
            obligation of Sellers, HealthFirst and the Principals hereunder (1)
            shall relate only to their direct or indirect percentage interest in
            such Partnership represented by the Transferred Partnership Interest
            in such Partnership and (2) shall be owing directly to Buyer and not
            such Partnership. Without limiting the generality of the foregoing,
            but subject to the limitations set forth above, Buyer shall have the
            right to be out in the same financial position as it would have been
            had each of the representations and warranties of HealthFirst,
            Sellers and the Principals been true and correct and had each of the
            covenants of HealthFirst, Sellers and the Principals been performed
            in full.

                        (iii) Any party that intends to enforce an indemnity
            obligation (the "Indemnified Party") shall give the party from whom
            indemnification is sought (the "Indemnifying Party") notice of any
            claim as soon as possible, but the failure to give such notice shall
            not relieve the Indemnifying Party of any of its obligations
            hereunder unless and only to the extent that the Indemnifying Party
            shall have been prejudiced thereby.

                        (iv) In the event such indemnification involves a claim
            by a third party (a "Third Party Claim"), the Indemnifying Party may
            elect to assume the defense of the Third Party Claim at its own
            expense with counsel selected by the Indemnifying Party and approved
            by the Indemnified Party (which approval shall not be unreasonably
            withheld), and the assertion of such right shall constitute an
            acknowledgment by the Indemnifying Party that such Third Party Claim
            is an indemnifiable claim for which the Indemnifying Party is
            responsible under this Section 8(a). If the Indemnifying Party
            assumes the defense of a Third Party Claim, (A) the Indemnifying
            Party shall not thereafter be liable for any fees or expenses of
            counsel for the Indemnified Party, (B) the Indemnified Party shall
            make available to the Indemnifying Party or its representatives all
            records and other materials reasonably required by the Indemnifying
            Party for use in contesting such Third Party Claim and shall
            cooperate fully with the Indemnifying Party in the defense thereof,
            (C) the Indemnified Party shall have the right to participate in the
            handling of such Third Party claim at its expense and (D) the
            Indemnified Party shall not voluntarily settle any such Third Party
            Claim without the prior written approval of the Indemnifying Party,
            which approval shall not be unreasonably withheld. If the
            Indemnifying Party does not assume such defense, the Indemnifying
            Party shall be liable for all costs and expenses incurred

                                       26
<PAGE>

            by the Indemnified Party in defending the Third Party Claim,
            including reasonable fees and disbursements of counsel.

                        (v) If, after having first provided the Indemnifying
            Party an opportunity to fulfill its obligations to the Indemnified
            Party hereunder, the Indemnified Party then brings an action against
            the Indemnifying Party upon any claim under this Section 8(a), the
            Indemnifying Party shall be liable to the Indemnified Party for its
            reasonable fees and disbursements of counsel in connection therewith
            if the Indemnified Party prevails in the action.

                        (vi) In case any event shall occur which would otherwise
            entitle any party to assert a claim for indemnification hereunder,
            no loss, damage or expense shall be deemed to have been sustained by
            such party to the extent of any proceeds received by such party from
            any insurance policies with respect thereto.

                        (vii) In order to secure any valid claim for
            indemnification that Buyer may have against HealthFirst or any
            Seller or Principal hereunder (but not as a sole source for the
            payment of any such claim), (A) HealthFirst and each Seller and
            Principal hereby grants to Buyer a security interest in any and all
            shares of Buyer Stock issued to any Seller or Principal pursuant to
            this Agreement or transferred by a Seller to any of its partners and
            (B) Buyer is authorized to retain any consideration that would
            otherwise be due to any Seller or Principal pursuant to this
            Agreement as to and to the extent necessary to pay any such valid
            claim for indemnification for which such party is liable and which
            has not been paid at the time Buyer is obligated to deliver such
            consideration under the terms of this Agreement. Buyer shall have no
            obligation to exercise its rights under this subsection (vii) in
            order to obtain payment of any indemnification obligation under this
            Section 8(a).

                  (b) Working Capital Requirements and Post-Closing Adjustment
of Purchase Price.

                        (i) Within 90 days after the Closing Date Buyer shall
            prepare and deliver to the Principals unaudited balance sheets and
            any other appropriate statements (the "Effective Date Balance
            Sheets") necessary to establish, as of the Effective Date: (A) 20%
            of the net working capital (defined in accordance with GAAP, but
            excluding cash and cash equivalent assets and excluding all
            Indebtedness that was outstanding on November 30, 1998 and included
            in the calculation of the amount payable pursuant to Section 1(a)
            above) of the Initial Partnerships; (B) 20% of the Initial
            Partnerships' outstanding Indebtedness (other than the November 30,
            1998 Indebtedness that is included in the calculation of the amount
            payable pursuant to Section 1(a) above), if any; (C) 20% of all
            employee benefit obligations with respect to employees whose costs
            are allocated to the Surgery Centers operated by the Initial
            Partnerships through the Center Support Organization and that are
            not included in the computation of net working capital pursuant to
            Clause (A) above; and (D) 100% of all employee benefit obligations
            of other employees of HealthFirst or any Seller, and other current
            liabilities (if

                                       27
<PAGE>

            any) of HealthFirst or any Seller not included in such net working
            capital calculation, that are assumed by Buyer pursuant to Section
            1(e)(iii). The amount obtained by subtracting the amounts described
            in clauses (B), (C) and (D) from the amount described in clause (A)
            is hereinafter referred to as the "Effective Date Working Capital".
            An example of the methodology used to calculate the Effective Date
            Working Capital of the Initial Partnerships as of July 31, 1998 is
            attached hereto as Schedule 15.

                        (ii) If the Effective Date Working Capital is less than
            $528,923, then Sellers shall pay to Buyer an amount equal to such
            shortfall.

                        (iii) If the Effective Date Working Capital is greater
            than $528,923, then Buyer shall pay Sellers an amount equal to such
            excess.

                        (iv) Each of the Initial Partnerships must have at least
            $50,000 in cash and cash equivalent assets as of the Effective Date.
            All cash assets in excess of $50,000 held by any Initial Partnership
            as of. the Effective Date shall be distributed to the partners of
            such Initial Partnership at or prior to the Closing Date.

                        (v) The payment, if any, required to be made under this
            Section 8(b) by Buyer to Sellers, or by Sellers to Buyer, as the
            case may be, shall be made based upon the Effective Date Balance
            Sheets unless a Principal notifies Buyer in writing of any objection
            thereto (which objection shall be specifically described therein)
            within 30 days after the Principals' receipt thereof. If a Principal
            notifies Buyer of any such objection, the Principals and Buyer shall
            use their best efforts to resolve such objection, but if they are
            not able to reach a resolution within 15 days after the date notice
            of such objection is delivered to Buyer, the matter shall be
            submitted to KPMG Peat Marwick LLP or, at the request of the
            Principals, to Ernst and Young, which accounting firm shall act as
            an expert and not as an arbitrator, for a final and binding
            determination of the Effective Date Working Capital. The expenses of
            such accounting firm in resolving any dispute shall be paid by Buyer
            if the final determination of the amount due under this Section 8(b)
            is changed in a manner that is favorable to Sellers by at least
            $25,000 as compared to the amount determined pursuant to the
            Effective Date Balance Sheets prepared by Buyer and, otherwise, such
            expenses shall be paid by Sellers.

                        (vi) The payment required by either Sellers or Buyer
            pursuant to this Section 8(b) shall be made promptly after the
            expiration of the 30 day period following Buyer's delivery of the
            Effective Data Balance Sheets to the Principals or, if a Principal
            notifies Buyer of an objection to the Effective Date Balance Sheets
            as described in subsection (v) above within such 30 day period, the
            payment shall be made promptly after resolution of such dispute as
            provided in subsection (v) above.

                  (c) Termination of Partnerships' Participation in Retirement
Plans. Subject to compliance with the current agreements between Administaff
Companies, Inc.

                                       28
<PAGE>

and either HealthFirst, Sellers or the Partnerships, upon termination of said
agreements with Administaff Companies, Inc., employees of HealthFirst, Sellers
and the Partnerships shall cease to participate in or accrue benefits under any
current pension, profit sharing or similar plan (the "Plans"). HealthFirst and
Sellers agree that, to the extent allowed by applicable laws and regulations, as
soon as practicable following the Closing, at the expense of HealthFirst and/or
Sellers (or, if applicable, their employee leasing company), they (or, if
applicable, their employee leasing company) will take all steps and make all
filings necessary or appropriate in order to terminate the participation of the
employees of HealthFirst, Sellers and the Partnerships in the Plans, and
HealthFirst and Sellers shall take any and all action necessary to authorize and
direct the administrator of the Plans to take such actions. HealthFirst
acknowledges and agrees that it and the Sellers (or, if applicable, their
employee leasing company) will retain responsibility for the funding,
administration and distribution of benefits under the Plans. Buyer agrees to use
its best efforts to facilitate the rollover of any and all funds and accounts
held for the participating employees of HealthFirst, Sellers and the
Partnerships who voluntarily elect to make such rollovers into one or more of
the pension and/or profit sharing plans maintained by Buyer or its affiliates,
as and to the extent such rollovers are permissible under applicable laws and
regulations.

                  (d) Books and Records; Personnel. For a period of seven years
from the Closing Date:

                        (i) Buyer shall not dispose of or destroy any of the
            material books and records of the Partnerships, Sellers or
            HealthFirst relating to periods prior to the Effective Date ("Books
            and Records") without first offering to turn over possession thereof
            to Sellers by written notice to Sellers at least 15 days prior to
            the proposed date of such disposition or destruction.

                        (ii) Buyer shall allow Sellers and their agents access
            to all Books and Records during normal working hours at Buyer's
            principal place of business or at any location where any Books and
            Records are stored, and Sellers shall have the right, at their
            expense, to make copies of any Books and Records; provided, however,
            that any such access or copying shall be had or done in such a
            manner so as not to interfere with the normal conduct of the
            Partnerships' businesses.

                        (iii) Buyer shall make available to Sellers upon written
            notice copies of any Books and Records, (B) Buyer's and the
            Partnerships' personnel to assist HealthFirst in locating and
            obtaining any Books and Records and (C) any of Buyer's or the
            Partnerships' personnel whose assistance or participation is
            reasonably required by Sellers or any of their affiliates in
            anticipation of, or preparation for, any investigation, inquiry,
            pending or threatened litigation, tax or other matters in which
            Sellers or any of their affiliates is involved; provided, however,
            that any such copying or assistance shall be had or done in such a
            manner so as not to interfere with the normal conduct of Buyer's and
            the Partnerships' businesses. Sellers shall reimburse Buyer for the
            reasonable direct and indirect expenses incurred by Buyer in
            performing the covenants contained in this Section 8(d)(iii).

                  (e) Offer to Purchase Additional Limited Partner Interests.

                        (i) Within 60 days following the Closing Date, and
            continuing until the first anniversary of the Closing Date, Buyer
            (or the wholly owned subsidiary to which Buyer has assigned its
            rights to acquire the Transferred Partnership Interests hereunder,
            all of which are for convenience referred to in this Section 8(e) as
            "Buyer") shall offer to purchase from each Initial Partnership newly
            authorized limited partnership interests that would, upon the issue
            and sale thereof, represent 50% of the total outstanding interests
            in such Partnership, subject to approval by the requisite percentage
            of the partners in such Partnership of an amendment to its
            Partnership Agreement (A) to authorize such issuance and sale, (B)
            to approve the use of the proceeds of such sale first to pay off any
            outstanding Indebtedness shown in Schedule 8A that is owing to
            HealthFirst or any Seller, Former Owner or Principal and then to
            distribute the balance to the partners in the Partnership according
            to their ownership interests in the Partnership following the
            issuance and sale of such new partnership interests and (C) to add a
            noncompetition covenant that is applicable to the limited partners
            (other than Buyer or any of its affiliates).

                        (ii) The purchase price offered to each Initial
            Partnership shall be seven times the earnings before interest,
            taxes, depreciation and amortization of such Partnership (the
            "Partnership EBITDA") for the 12 calendar months (the "Base Year")
            ended prior to the date of the closing of such sale, less the
            Partnership's outstanding debt as of the last day of the Base Year,
            plus three times the increase (if any) in the average 12 month
            Partnership EBITDA for the period from the end of the Base Year to
            the end of Year Two (as defined in Section 1(c)(i)(A) above) over
            the Partnership EBITDA for the Base Year, plus three times any
            increase in the Partnership EBITDA for Year Three over the greater
            of the Partnership EBITDA for the Base Year or the average 12 month
            Partnership EBITDA for the period from the end of the Base Year to
            the end of Year Two, provided, however, that the aggregate amount
            payable to any Partnership pursuant to clauses (B) and (C) shall not
            exceed 25% of the amount payable pursuant to clause (A).

                        (iii) The purchases provided for in this Section 8(e)
            shall be consummated as soon as practicable following Buyer's
            calculation of the Partnership EBITDA of each Initial Partnership
            for the Base Year (and, if applicable, the resolution of any dispute
            between Buyer and the Principals relating to Base Year Partnership
            EBITDA calculation pursuant to the third paragraph of Section 1(c)
            above), at which time the portion of the purchase price calculated
            pursuant to subsection 8(e)(ii)(A) above shall be paid. The payments
            to be made pursuant to subsections 8(e)(ii)(B) and 8(e)(ii)(C) above
            shall be made within 60 days after the end of Year Two and Year
            Three, respectively.

                        (iv) If Buyer is successful in purchasing additional
            limited partnership interests in any Initial Partnership pursuant to
            this Section 8(e), then (A) Buyer shall be obligated to pay to the
            Partnership Sellers an additional

                                       30
<PAGE>

            amount equal to (in the aggregate) (I) seven times the percentage
            interest in such Initial Partnership represented by the Transferred
            Partnership Interest therein sold to Buyer pursuant to Section 1
            multiplied by the Base Year Partnership EBITDA minus (II) the
            allocation of the payment made by Buyer to Sellers pursuant to
            Section 1(a) that is attributable to such Initial Partnership (as
            adjusted pursuant to Section 8(b) above), as identified in Schedule
            5, which payment shall be made concurrently with the payment to the
            Initial Partnership of the initial installment of the purchase price
            pursuant to subsection (ii)(A) above, and (B) no payment shall be
            due to the Partnership Sellers with respect to the Year One EBITDA
            attributable to such Initial Partnership pursuant to Section
            1(c)(i).

                        (v) All payments made pursuant to this Section 8(e)
            shall be payable one-half to each Partnership Seller in cash by
            Buyer's checks or, if wire transfer instructions are given to Buyer
            at least three business days prior to the payment date, by wire
            transfer of immediately available funds.

                  (f) Management and Option to Purchase Fort Worth Surgery
Center. The Partnership Sellers are the sole general partners of Fort Worth
Surgicare Partners, Ltd. (the "Fort Worth Partnership"). The Fort Worth
Partnership has been formed for the purpose of developing, owning and operating
an outpatient surgery center in Fort Worth, Texas (the "Fort Worth Surgery
Center") and has concluded the syndication of its limited partnership interests
to local investors (the "Other Fort Worth Partners") . The Principals represent
and warrant that the foregoing facts are true and correct and anticipate that
the Fort Worth Surgery Center should be completed and opened on or about March
31, 1999, and Principals know of no reason why such completion and opening
schedule will not be met, it being understood by Buyer that construction
projects are subject to circumstances beyond the Principals' control and acts of
God. Sellers agree that, if the Closing occurs, the Fort Worth Partnership will
engage Buyer (or its designated subsidiary) to manage the Fort Worth Surgery
Center and Buyer will have an option to purchase Sellers' interests in the Fort
Worth Partnership, as follows:

                        (i) At the Closing the Management Sellers will assign to
            Buyer (or a designated wholly owned subsidiary of Buyer) the
            HealthFirst Management Agreement with the Fort Worth Partnership
            whereunder Buyer (or its subsidiary) will provide day-to-day
            management services to the Fort Worth Surgery Center for a
            management fee equal to 7% of the net revenues of the Fort Worth
            Surgery Center.

                        (ii) The Partnership Sellers hereby grant to Buyer an
            option to purchase their respective general partner interests and
            any limited partner interest in the Fort Worth Partnership held by
            the Partnership Sellers, which option shall be exercisable by Buyer
            giving written notice of exercise to the Partnership Sellers or any
            Principal at any time during the 60 day period that begins 18 months
            after the date that the Fort Worth Surgery Center receives Medicare
            certification, which date shall be identified by a written notice to
            be given by a Principal to Buyer following receipt of said
            certification and is hereinafter referred to as the "Medicare
            Certification Date." If Buyer properly exercises such option to
            purchase the Partnership Sellers' interests in the Fort Worth
            Partnership,

                                       31
<PAGE>

            the purchase price shall be equal to six times the EBITDA (defined
            and calculated as described in Section 1(c)(i)(A) and subject to the
            dispute resolution provisions set forth in the third paragraph of
            Section 1(c) above) attributable to management fees from and the
            percentage interest in the Fort Worth Partnership to be purchased
            for the most recent 12 calendar month period ended on or immediately
            prior to the date that is 18 months after the Medicare Certification
            Date, less such percentage of the outstanding debt of the Fort Worth
            Partnership as of the end of such 18 calendar month period.

                        (iii) If Buyer exercises its option to acquire the
            Partnership Sellers' interests in the Fort Worth Partnership
            pursuant to subsection (ii) above, Buyer shall thereupon make an
            offer to the Other Fort Worth Partners to acquire additional
            interests in the Fort Worth Partnership, which offer shall be on the
            terms described in Section 8(e)(i) and shall remain outstanding
            until the second anniversary of the Medicare Certification Date. The
            purchase price to be offered to the Other Fort Worth Partners shall
            be the same as the price paid to the Partnership Sellers, except
            that the multiple of EBITDA shall increase to seven and, if the
            requisite percentage of the Other Fort Worth Limited Partners vote
            to approve the sale of such interests in the Fort Worth Partnership,
            the purchase price payable to the Partnership Sellers for their
            interests in the Fort Worth Partnership pursuant to subsection (ii)
            shall also be increased to be based upon a seven times multiple. Any
            such additional amount payable to the Partnership Sellers pursuant
            hereto shall be paid concurrently with Buyer's completion of its
            purchase of the additional interests in the Fort Worth Partnership.

                        (iv) Prior to the closing of any purchase of interests
            in the Fort Worth Partnership pursuant to subsection (ii) or (iii)
            above, the Fort Worth Partnership shall distribute to its partners
            all cash assets in excess of $50,000 held as of the effective date
            of such purchase.

                        (v) If Buyer does not exercise its option to purchase
            the Partnership Sellers' partnership interests in the Fort Worth
            Partnership pursuant to subsection (ii) above, the Management
            Agreement assigned to Buyer pursuant to subsection (i) above shall
            be reassigned to the Management Sellers on the date that is 21
            months after the Medicare Certification Date, whereupon Buyer shall
            be obligated to pay to the Management Sellers an amount equal to
            5/7ths of the total management fees paid by the Fort Worth
            Partnership to Buyer pursuant to said Management Agreement.

                        (vi) All payments made pursuant this Section 8(f) shall
            be payable in cash by Buyer's checks or, if wire transfer
            instructions are given to Buyer at least three business days prior
            to the payment date, by wire transfer of immediately available
            funds.

                  (g) Management and Option to Purchase Valley View Surgery
Center. As indicated in Recitals B and G above, the Principals and Kathleen
Disney own certain of the issued and outstanding stock of VVSC, which is the
managing general partner of DSP.

                                       32
<PAGE>

The Principals and VVSC agree that, if the Closing occurs, DSP will engage Buyer
(or its designated subsidiary) to manage the Valley View Surgery Center and
Buyer will have an option to purchase a portion of VVSC's interest in DSP, as
follows:

                        (i) Pursuant to Section 1, at the Closing the Management
            Sellers will assign to Buyer the existing Management Agreement with
            DSP whereunder Buyer (or its subsidiary) will provide day-to-day
            management services to DSP for a management fee equal to 6% of the
            net revenues of the valley View Surgery Center (where "net revenues"
            are defined as gross revenues less contractual allowances and
            adjustments for uncollectible accounts and charity work, all
            determined in accordance with GAAP).

                        (ii) VVSC hereby grants to Buyer an option to purchase
            the percentage interest in DSP held by VVSC equal to the percentage
            interest in VVSC held by the Principals and Kathleen Disney (as
            reflected in Schedule 1) multiplied by the percentage interest in
            DSP held by VVSC (as reflected in Schedule 1), which option shall be
            exercisable by Buyer giving written notice of exercise to VVSC or
            any Principal at any time during the 60 day period that beings 12
            months after the Closing Date or, with the consent of the VVSC and
            the Principals, at any time during the initial 12 months following
            the Closing Date. If Buyer properly exercises such option to
            purchase said portion of VVSC's interest in DSP, the purchase price
            shall be equal to six times the EBITDA (defined and calculated as
            described in Section 1(c)(i)(A) and subject to the dispute
            resolution escrows set forth in the third paragraph of Section 1(c)
            above) attributable to the percentage interest in DSP to be
            purchased for the most recent 12 calendar month period ended on or
            immediately prior to the date on which the notice of exercise is
            given, less said percentage of the outstanding debt of DSP as of the
            end of such 12 month period. In addition, the completion of the
            purchase of said portion of VVSC's interest in DSP shall be subject
            to satisfaction of the following conditions: (A) the requisite
            percentage of the partners of DSP shall have approved an amendment
            of the Partnership Agreement of DSP to designate Buyer (or its
            subsidiary) as the managing partner of DSP (having powers and
            authority similar to the sole general partner of a Texas limited
            partnership); and (B) VVSC and the Principals and shall have agreed
            to a redemption of the shares in VVSC held by the Principals and
            Kathleen Disney, using the proceeds of the sale of the partnership
            interest in DSP pursuant hereto.

                        (iii) The Principals and VVSC will use their best
            efforts as soon as is reasonably practicable following the Closing
            Date (A) to cause DSP to issue and sell to new investors who are
            approved by both VVSC and Buyer newly authorized and issued
            partnership interests in DSP representing up to a 12% interest in
            DSP, and (B) to amend the existing lease agreement between DSP and
            Valley View MOB, a Texas general partnership that owns the building
            in which Valley View Surgery Center conducts business, which
            amendment shall be in form and substance reasonably satisfactory to
            Buyer, provide for the elimination of any "percentage rent" and set
            the rental rate thereunder at the current fair market rental value
            of the leased premises.

<PAGE>

                        (iv) If Buyer exercises its option to acquire a portion
            of VVSC's interest in DSP pursuant to subsection (ii) above, Buyer
            shall thereupon make an offer to VVSC and the other partners (as of
            the Closing Date) in DSP (the "Other Valley View Partners") to
            purchase one-half of their respective interests in DSP, which offer
            shall remain outstanding until the first anniversary of the Closing
            Date. The purchase price offered to the Other Valley View Partners
            shall be the same as the price paid to VVSC pursuant subsection
            (ii), except that the multiple of EBITDA shall increase to seven if
            all of the Other Valley View Partners accept such offer and agree to
            sell one-half of their respective interests in DSP, in which event
            the purchase price payable to VVSC for its interest in DSP pursuant
            to subsection (ii) shall also be increased to be based upon a seven
            times multiple. Any such additional amount payable to VVSC pursuant
            hereto shall be paid concurrently with Buyer's completion of its
            purchase of one-half of the interest of the Other Valley View
            Partners.

                        (v) Prior to the closing of any purchase of interests in
            DSP pursuant to subsection (iii) or (iv) above, DSP shall distribute
            to its partners all cash assets in excess of $50,000 held as of the
            effective date of such purchase.

                        (vi) All payments made pursuant to this Section 8(g)
            shall be made, pursuant to the Principal's written instructions, in
            cash by Buyer's checks or, if wire transfer instructions are given
            to Buyer at least three business prior to the payment date, by wire
            transfer of immediately available funds.

                  (h) Tax Election. If requested by Buyer, each Seller shall,
either at the Closing or thereafter, cause the Partnerships to make the election
permitted under Section 754 of the Code.

                  (i) Certain Tax Matters.

                        (i) Buyer and Sellers acknowledge and agree that the
            taxable income, losses, deductions, credits and similar items
            generated by the Partnerships during the Partnerships' tax years
            ending December 31, 1998 shall be allocated among Sellers and Buyer
            based on the number of days in 1998 before and after the Effective
            Date, except that for DeSoto such allocation shall be based on an
            interim closing of DeSoto's books on the Effective Date.

                        (ii) Buyer shall prepare or cause to be prepared, and
            shall file or cause to be filed, the 1998 partnership income tax
            returns for the Partnerships Buyer shall permit Sellers to review
            and comment on each such partnership tax return prior to filing
            Buyer shall follow Sellers' requests for any changes in such returns
            as and to the extent such change, in the reasonable judgment of
            Buyer's independent accountants who are responsible for preparing
            such tax returns, (A) constitutes a reasonable filing position and
            (B) either (I) is consistent with the past practices of the
            Partnership or (II) relates to a matter that will not have any
            effect on the Partnership's returns for calendar years 1999 and
            thereafter.

                                       34
<PAGE>

                        (iii) Buyer and Sellers shall cooperate fully, as and to
            the extent reasonably requested by the other party, in connection
            with the filing of tax returns pursuant to this Section 8(i) and any
            audit, litigation or other proceeding with respect to federal, state
            or local taxes of the Partnerships for 1998. Such cooperation shall
            include the retention and (upon the other party's request) the
            provision of records and information which are reasonably relevant
            to any such audit, litigation or other proceeding and making
            employees available on a mutually convenient basis to provide
            additional information and explanation of any material provided
            hereunder.

                  (j) Texas Health Ventures Group. HealthFirst, Sellers and the
Principals agree to assist Buyer in its current discussions with Baylor Health
Care System regarding Buyer's proposed acquisition of the interest in THVG held
by Bingham THVG, L.L.P. and Disney THVG, L.L.P. and the expansion of THVG to
include the Surgery Centers and certain outpatient surgery centers currently
owned by Baylor Health Care System.

                  (k) Assignment of Surgery Center Personnel. Until three years
after the Closing Date or the date on which the maximum payments have been made
pursuant to Section 1(c), whichever is sooner, Buyer must obtain the approval of
a Principal before assigning a task to any person who is an employee of a
Surgery Center or HealthFirst on or before the Closing Date if such task does
not relate to the business of that employee's Surgery Center, provided, however,
that (i) such approval shall not be unreasonably withheld and (ii) the
Principals acknowledge that certain services will be required of Surgery Center
personnel in order to integrate the operations and financial reporting of the
Surgery Centers into Buyer's overall operations and financial reporting system.

                  (l) Payment of Certain Indebtedness. Payments on the
Indebtedness described in Schedule 8A that is owing to HealthFirst or any
Seller, Former Owner or Principal (the "HealthFirst Debt") shall be due by the
Partnerships only as follows: (i) the proceeds of any sale of interests in a
Partnership pursuant to Section 8(e) or 8(f)(iii) shall be used first to pay off
the HealthFirst Debt owing by such Partnership, and (ii) to the extent the
proceeds of any such sale of Partnership interests by a Partnership are not
sufficient to pay that Partnership's HealthFirst Debt in full, or if no such
sale is made, the unpaid portion of the HealthFirst Debt shall be due and
payable in 36 equal monthly installments beginning on the first day of the
calendar month following the date of the sale of Partnership interests (if
applicable) or the date that Buyer's offer to purchase Partnership interests
expires pursuant to Section 8(e)(i) or 8(f)(iii), as the case may be.

                  (m) Effective Date of Employment Agreements. The Employment
Agreements to be entered into by Buyer and the Principals pursuant to Sections
6(j) and 7(e) are not effective until January 1, 1999 and, accordingly, the
Principals shall continue to be employed by Administaff Companies, Inc. through
December 31, 1998 and shall be entitled to all employee benefits in effect under
such arrangement. During the period from the Effective Date through December 31,
1998, however, the Principals' base salaries under such arrangement shall be as
set forth in their respective Employment Agreements.

                  (n) Noncompetition Covenants. The Sellers, HealthFirst and the
Principals (who are collectively referred to in this Section 8(n) as the
"Covenantors" and, individually, as a "Covenantor") each hereby agrees, as to
himself or itself and not as to any other Covenantor, as follows:

                        (i) For a period of five years from and after the
            Closing Date, such Covenantor will not own, acquire or have any

            ownership interests held by immediate family members of any
            Principal or trusts for the benefit of any Principal's immediate
            family members), in any outpatient surgery center or in any hospital
            with surgical facilities located within a 30 mile radius of any of
            the Surgery Centers or any of the hospitals or outpatient surgery

            (collectively, the "Non-Compete Areas"), including an operating room
            or rooms in doctors' offices where surgical procedures are performed
            that are customarily performed in hospitals or outpatient surgical
            centers or for which a facility fee is charged, or in any other firm
            or entity that owns or operates such a surgical center or hospital
            within any Non-Compete Area; provided, however, that this subsection
            (i) shall not apply to (A) any direct or indirect ownership interest
            held by any Covenantor in THVG, (B) the ownership interest of the
            Principals or their family members in HealthFirst or any Seller, (C)
            any ownership interest with Prime Medical or an affiliate in an

            are unrelated to surgical services.

                        (ii) During the five year period referred to in
            subsection (i) above, such Covenantor shall not (A) be engaged as an
            employee, officer, director, agent, manager or consultant, or in any
            similar capacity, with any firm or entity in which Covenantor would
            not be permitted to have a financial interest pursuant to the
            provisions of subsection (i) above; (B) influence or attempt to
            influence, either directly or indirectly, any physician, supplier,
            health care facility, preferred provider organization, health
            maintenance organization or other third party payor not to continue
            such person's or entity's relationship with Buyer or its domestic
            affiliates; (C) knowingly solicit any patient of Buyer or its
            domestic affiliates to obtain medical services in outpatient surgery
            centers; or (D) solicit (other than solicitations in the form of
            general employment advertisements placed in newspapers or other
            publications of general circulation), induce or attempt to induce
            any employee, independent contractor, consultant, physician or any
            other person associated with Buyer or any of its domestic affiliates
            to leave the employment of, or to otherwise discontinue his, her or
            its association with, Buyer or such domestic affiliate.

                        (iii) If this Section 8(n) is declared unenforceable in
            any judicial proceeding for being of too long a duration or covering
            too large a geographic

                                       36
<PAGE>

            area, then this Section 8(n) shall still be enforceable for such
            maximum period of time and within such geographic area as will make
            the provisions hereof enforceable.

                        (iv) The Covenantors acknowledge that the rights and
            privileges granted to Buyer herein are of special and unique
            character, which gives them a peculiar value, the loss of which may
            not be reasonably or adequately compensated for by damages in an
            action at law, and that a breach by any Covenantor of this Section
            8(n) will cause Buyer great and irreparable injury and damage.
            Accordingly, the Covenantors hereby agree that Buyer, together with
            its affiliates or any of them, shall be entitled to remedies of
            injunction, specific performance or other equitable relief to
            prevent a breach of this Section 8(n). This provision shall not be
            construed as a waiver of any other rights or remedies which Buyer
            may have for damages or otherwise.

            9. Termination.

                  (a) By Mutual Consent. This Agreement may be terminated
without further obligation of the parties at any time prior to Closing by mutual
consent of the parties hereto.

                  (b) Damages. No party shall be liable in damages to any other
party as a result of the failure to consummate the Closing transactions
contemplated by this Agreement unless such failure is caused by the material
breach of such party of any of the terms of this Agreement.

                  (c) Unilateral Termination. If, through no fault of or breach
by a party hereto, the Closing is not consummated on or before December 31,
1998, this Agreement may be unilaterally terminated by written notice given by
such party to the other parties If the Closing has not occurred by December 31,
1998, but the parties do not terminate this Agreement pursuant to this Section
9(c), either party may require that the purchase price for the Transferred
Assets be recalculated as described in paragraph 2(i) of the letter of intent,
dated as of August 6, 1998, between HealthFirst and Buyer.

            10. Assignment. None of the parties hereto shall assign any of its
rights or obligations hereunder without the prior written consent of the other
parties hereto, provided, however, that at or prior to the Closing Buyer may
assign its rights hereunder to one or more wholly owned subsidiaries of Buyer.

            11. Notices. All notices, requests, demands and other communications
required or permitted to be given hereunder shall be in writing and shall be

SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE INTERNAL
LAWS OF THE STATE OF TEXAS. The section headings contained herein are for

this Agreement or to affect the meaning or interpretation of this Agreement in
any way.

            13. General. This Agreement (including the Schedules and Exhibits
referred to herein) sets forth the entire agreement and understanding of the
parties with respect to the transactions contemplated hereby and supersedes all
prior agreements, arrangements and understandings related to the subject matter
hereof, including without limitation the letter of intent, dated as of August 6,
1998, between HealthFirst and Buyer. No representation, promise, inducement or
statement of intention has been made by any party hereto which is not embodied
in this Agreement, or in the Exhibits hereto or the written statements,
certificates or other documents delivered pursuant hereto. All the terms,
provisions, covenants, representations, warranties and conditions of this
Agreement shall survive the Closing and shall be binding upon and inure to the
benefit of and be enforceable by the parties hereto and their respective
successors and assigns. This Agreement may be amended, modified, superseded or

<PAGE>

and any of the terms, provisions, covenants, representations, warranties or
conditions hereof may be waived, only by a written instrument executed by all
parties hereto, or, in the case of a waiver, by the party waiving compliance.
The failure of any party at any time or times to require performance of any
provision hereof shall in no manner affect the right to enforce the same. No
waiver by any party of any condition, or of the breach of any term, provision,
covenant, representation or warranty contained in this Agreement, whether by
conduct or otherwise, in any one or more instances, shall be deemed to be or
construed as a further or continuing waiver of any such condition or breach or a
waiver of any other condition or of the breach of any other term, provision,
covenant, representation or warranty. In the event that any one or more of the
provisions of this Agreement shall be held or otherwise found to be invalid,
illegal or unenforceable, all other provisions hereof shall be given effect
separately therefrom and shall not be affected thereby. This Agreement is for
the sole benefit of the undersigned parties hereto and is not for the benefit of
any third party.

            14. Further Assurances. HealthFirst, Sellers and Principals shall
execute and deliver such other documents and instruments, and take such other
actions, as Buyer may reasonably request in order more fully to vest and perfect
in Buyer all right, title and interest in and to the Transferred Assets. Buyer

actions, as HealthFirst or any Principal may reasonably request in order to more
fully provide to HealthFirst, Sellers and Principals the intended benefits of
this Agreement.

            15. Counterparts; Facsimile Signatures. This Agreement may be
executed in one or more counterparts, all of which together shall constitute one
and the same instrument. It shall not be necessary in making proof of this
Agreement to produce or account for more than one such counterpart. A facsimile
copy of a signature hereto shall be effective as if an original.

            16. Attorneys' Fees. In any action at law or equity to enforce any
of the provisions or rights under this Agreement, the unsuccessful party to such
litigation, as determined by the court in any final judgment or decree, shall
pay the successful party or parties all costs, expenses and reasonable
attorneys' fees incurred therein by such party or parties (including without
limitation such costs, expenses and fees on any appeal or in connection with any
bankruptcy proceeding), and if the successful party recovers judgment in any
such action or proceeding, such costs, expenses and attorneys' fees shall be
included in and as a part of such judgment.

            17. Confidentiality. In the event that this Agreement is terminated
pursuant to Section 9 hereof, or otherwise, or the Closing does not occur by
reason of failure of one of the conditions to the Closing, each of the parties
hereto agrees (a) to return to the other parties all documents, financial
statements and other information furnished or copied in connection with the
transactions contemplated by this Agreement and (b) not to disclose without the
prior written consent of the disclosing party any information obtained with
respect to the business or operations of such other party or any affiliate of
such party.

            18. Dispute Resolution Mechanisms. The parties have agreed on the
following mechanisms in order to obtain prompt and expeditious resolution of
disputes hereunder:

                                       39
<PAGE>

                  (a) Binding Arbitration. If any dispute arises between the
parties with respect to the interpretation or enforcement of this Agreement, the
parties agree to work in good faith to resolve such dispute or disagreement in
good faith and, if they are unable to resolve the dispute within 15 days, they
shall submit it to binding arbitration.

                  (b) Choice of Arbitrator. If the parties can agree to a single
arbitrator within 30 days of one party receiving notice from the other party of
the dispute or disagreement, such arbitrator shall be chosen. The arbitrator(s)
shall not be required to have qualifications other than a reasonable amount of
experience and specialty in the area which is the subject of the dispute.

                  (c) Failure to Choose Arbitrator. If the parties do not agree
as to the choice of an arbitrator, each party shall choose an arbitrator within
10 days after the expiration of the 30 day period referred to in Section 18(b)
and those chosen arbitrators shall choose an additional arbitrator within 20
days of the date in which the last arbitrator is chosen. If at the end of said
20 days the parties' designated arbitrators cannot agree on the selection of the
third arbitrator, such selection shall be made by the American Arbitration
Association office located nearest to Buyer's headquarters office in Dallas,
Texas upon the application of either party.

                  (d) Conduct. The arbitration shall be conducted pursuant to
the Commercial Rules of the American Arbitration Association; provided, however,
that the federal rules of civil procedure, evidence and discovery shall be
applicable to such arbitration proceeding (including without limitation the
requirement that all witnesses may be deposed under oath). The parties shall
diligently cooperate with one another and the arbitrator(s), and shall perform
such acts as may be necessary to obtain a prompt and expeditious resolution of
the dispute. If either party refuses to diligently cooperate and the other
party, after first giving notice of its intent to rely on the provisions of this
Section 18(d), incurs additional expenses or attorneys' fees as a result of such
failure to diligently cooperate, the arbitrator(s) may award such additional
expenses and attorneys' fees to the party giving such notice, even if such party
is not the prevailing party in the dispute.

                  (e) Resolution of Dispute. The dispute between the parties
shall be heard by the arbitrator(s) within 90 days after the date on which the
arbitrator(s) have been chosen. The arbitrator(s) shall, by a majority vote,
resolve any dispute or disagreement within 30 days of hearing the dispute The
arbitrator(s) shall render a reasoned, written opinion, citing applicable case
law and statutes.

                  (f) Effect of Arbitration. The decision of the arbitrator(s)
shall be final and binding on the parties.

                  (g) Allocation of Costs. The cost of the arbitration shall
initially be borne equally by the parties to the dispute, but the prevailing
party in such arbitration shall be entitled to recover, in addition to
reasonable attorneys' fees and all other costs, its contribution for the
reasonable cost of the arbitrator(s) as an item of recoverable costs. If either
party refuses to pay its share of the costs of the proceeding at the time(s)
required, the other party may do so, in which event that party will be entitled
to recover (or offset) the amount advanced, with interest

                                       40
<PAGE>

at the maximum rate permitted by law, even if that party is not the prevailing
party. The arbitrator(s) shall include such costs in the judgment or award.

            19. Remedies. Except as otherwise expressly provided in this
Agreement, following the Closing, the indemnification provisions set forth in
Section 8(a) of this Agreement shall be the sole and exclusive remedy of the
parties hereto for breaches of representations and warranties, covenants and
other agreements.

            20. Interpretation of Agreement. The parties hereto acknowledge and
agree that this Agreement has been negotiated at arm's length and between
parties equally sophisticated and Knowledgeable in the matters dealt with in
this Agreement Accordingly, any rule of law or legal decision that would require
interpretation of any ambiguities in this Agreement against the party that has
drafted it is not applicable and is waived. The provisions of this Agreement
shall be interpreted in a reasonable manner to effect the intent of the parties
as set forth in this Agreement.

      4.2 Right of First Refusal. After the fifth anniversary of these
Regulations and subject to this Section 4.2, any Member (the "Offering Holder")
who desires to Dispose of Membership Interests to a bona fide prospective
third-party purchaser independent of the Offering Holder ("Third-Party
Purchaser") for value shall give a written notice ("Offering Notice") signed by
the Offering Holder to the Company and the other Member(s) of such Offering
Holder's desire to do so. The Notice shall be sent in accordance with Section
18.2 and shall set forth in reasonable detail the terms and provisions of the
proposed Disposition, including, without limitation, (i) the Membership
Interest(s) to be Disposed of (the "Offered Interest"), (ii) the identity and
address of the Third-Party Purchaser to whom the Offering Holder proposes to
Dispose of the Offered Interest and (iii) the price (the "Offered Price"), terms
and conditions of the proposed Disposition. The Offering Holder may Dispose of
the Offered Interest only as follows:

            (a) The non-selling Member(s) shall have the option, but not the
obligation, for thirty (30) Business Days following receipt of the Offering
Notice, to purchase all, but not less than all, of the Offered Interest at a
price established pursuant to Section 4.2(c) (which if there are more than one
non-selling Members that desire to purchase the Offered Interest shall be in
proportion to their Membership Interests).

            (b) If the non-selling Member(s) does not exercise its option with
respect to the Offered Interest, the Offering Holder shall, in accordance with
Section 18.2, notify the Company of the Offered Interest, and the Company shall
have the option, but not the obligation, for thirty (30) Business Days following
the expiration of the non-selling Member's(s') option, to purchase not less than
all of the Offered Interest at a price established pursuant to Section 4.2(c).

            (c) The price that the Member(s) or the Company (the "Purchaser(s)")
will pay to the Offering Holder under Section 4.2(a) or (b), as appropriate,
will be the lower of (i) the Offered Price and (ii) a price per Membership
Interest based on a Membership Interest's Agreed Value (defined herein). The
"Agreed Value" of each Membership Interest will equal (x) the Fair Market Value
of the Company (as determined pursuant to this Section 4.2(c)) (y) divided by
the number of Membership Interests issued and outstanding at the time of the
Offering Notice. For purposes of this Article IV and Articles V and XV only, the
"Fair Market Value" of the Company shall be determined as follows:

      If the Purchaser(s) give notice to the Offering Holder that the
Purchaser(s) intend to purchase the Offered Interest, a qualified appraiser
agreed upon by the Purchaser(s) and the Offering Holder will determine the
Company's Fair Market Value. If the Purchaser(s) and the Offering Holder cannot
agree on an appraiser within thirty (30) days after the giving of the Offering
Notice, the Purchasers) will name one (1) qualified appraiser and the Offering
Holder will name one (1) qualified appraiser, in each case by notice delivered
in accordance with Section 18.2 to the other parties, within ten (10) days after
such 30-day period elapses. If only one party delivers the name of a qualified
appraiser within such l0-day period, then such appraiser shall be deemed to be
the agreed upon appraiser for purposes of this Section 4.2(c). If both the
Purchaser(s) and the Offering Holder name a qualified appraiser in accordance
with this Section 4.2(c), these appraisers shall select a third appraiser and
all three appraisers shall independently and promptly appraise the Fair Market
Value of the Company and deliver written reports of such appraisals to all
parties. These appraisals shall be averaged, the appraisal that differs most
from the average shall be disregarded, and the average of the remaining
appraisals shall be the Fair Market Value of the Company for purposes of this
Section 4.2(c). If one appraiser is used under this Section 4.2(e), then the
Purchaser(s) will pay one-half (1/2) of appraisal cost and the Offering Holder
will pay one-half (1/2) of the appraisal cost. If more than one appraiser is
used under this Section 4.2(c), then each party will pay the cost of the
appraiser it selects and the Purchaser(s) will pay one-half (1/2) of the cost of
the third appraiser and the Offering Holder will pay one-half (1/2) of the cost
of the third appraiser.

                                       13

            (d) The closing of the purchase of the Offered Interest shall be
within ninety (90) days from the date of the Offering Notice. Payment of the
purchase price shall be made by certified car cashier's check at the Closing.

            (e) The Purchaser(s) shall exercise their options to purchase the
Offered Interests hereunder by actual delivery to the Offering Holder of a
written notice of intent to purchase such Offered Interest given in accordance
with Section 18.2. Upon the exercise of an option, the Purchaser(s) shall be
obligated to make payment at the closing as provided in Section 4.2(d).

            (f) If neither the non-selling Member(s) nor the Company elects to
purchase all of the Offered Interest during the option periods, the options to
purchase the Offered Interest shall be deemed to be lapsed without exercise by
the non-selling Member(s) or the Company, and the Offering Holder shall be
permitted, at any time or times within, but not after, thirty (30) days after
the expiration of the option periods to sell the Offered Interest which was the
subject of the Offering Notice; provided, however, that no such sale shall be
made at a lower price or to any Third-Party Purchaser other than as specified in
the Offering Notice. Any Third-Party Purchaser purchasing the Offered Interest
in accordance with the terms of this Section 4.2(f) shall comply with the
provisions of Section 4.4.

      4.3 Compliance with Section 17.2. On the occurrence of any event that

must comply with Section 17.2.

and USP) may become a Member without the consent of all existing Members. No
assignee, other than Baylor and UP, taking or acquiring, by whatever means, the
Membership Interest of any Member shall be admitted as a Successor Member unless
such admission is approved by all of the existing Members; provided, however,
that a Person acquiring Membership Interest pursuant to Section 4.1(a), Section
4.2(f) or Article V may be admitted as a Member with respect to such Membership
Interest without the consent of any Member. To become a Member, an assignee of

respect to such Membership Interest.

the Company, at the request of the transferee of the interest the president may,

provisions of this Article IV either directly or indirectly or through its
agents by entering an appropriate stop transfer order on its books or otherwise

Membership Interest in the Company during any accounting period in compliance
with the provisions of this Article IV, Company income, gain, deductions and
losses attributable to such interest for the respective period shall be divided
and allocated between the transferor and the transferee by taking into account
their varying interests during the applicable accounting period in accordance
with Code section 706(d). All Company distributions on or before the effective
date of such transfer shall be made to the transferor, and all such Company

      "SEE RESTRICTIONS ON TRANSFER HEREOF ON REVERSE SIDE."

      4.11 Information. In addition to any other rights specifically set forth
in these Regulations, each Member is entitled to all information to which that
Member is entitled to have access pursuant to Article 2.22 of the Act under the
circumstances and subject to the conditions therein stated.

      4.12 Lack of Authority. No Member (other than a Manager or an officer of
the Company, acting in such capacity) has the authority or power to act for or
on behalf of the Company, to do any act that would be binding on the Company, or

                                   Article V
                             CAPITAL CONTRIBUTIONS

      5.1 Initial Contributions. Each initial member made an initial Capital
Contribution to the Company equal to the amount set forth on Exhibit A to these
Regulations, opposite the initial member's name. In addition, each initial
Member shall make the contributions required by the Contribution Agreement.

      5.2 Subsequent Contributions.

            (a) Without creating any rights in favor of any third party, each
Member may be asked by the Managers to contribute to the Company in cash, on or
before a date approved by the Managers (the "Contribution Date"),that Member's
share (as determined by the Member's Ownership Interest, without regard to any
Current Year Section 5.8 Adjustments) of all monies that, in the judgment of the
Managers, are necessary to enable the Company to cause the business of the
Company to be properly operated and maintained and to discharge its costs,
expenses, obligations and liabilities. The Managers shall notify each Member (a
"Capital Call") of the need for Capital Contributions pursuant to this Section
5.2 when appropriate. This notice must include a statement in reasonable detail
of the current financial condition of the Company, the reasons) for the Capital
Call and the proposed uses of the Capital Contributions. To the extent a Member
(a "Non-Contributing Member") cannot or elects not to contribute Capital
Contributions requested pursuant to this Section 5.2, the Managers shall notify
the other Member(s) (the "Contributing Member(s)") of such fact and shall
request that additional Capital Contributions be made by one or more of the
Contributing Member(s) in an amount equal to the amount originally requested of
the Non-Contributing Member, and a Contributing Member may make an additional
Capital Contribution (a "Shortfall Contribution") of a portion or all of such
amount.

            (b) Subject to Section 5.2(c), to the extent a Non-Contributing
Member cannot or elects not to make Capital Contributions requested pursuant to
this Section 5.2, the Non-Contributing Member's Ownership Interest will be
decreased proportionately (and the Contributing Member's Ownership Interest
increased proportionately) so that Ownership Interests are proportionate to the
FMV Capital Accounts after the Capital Contributions. Subject to Section 5.2(c),
to the extent that any Contributing Member(s) makes a Shortfall Contribution,
such Contributing Member's(s') Ownership Interests) will be increased
proportionately (and the Non-contributing Member's Ownership Interest decreased
proportionately) so that Ownership Interests are proportionate to the FMV
Capital Accounts after the Capital Contributions. The

                                       16
<PAGE>

proportionate increase and decrease in Ownership Interest under this Section
5.2(b) will be made in accordance with Section.

            (c) The proportionate increases and decreases in Ownership Interests
required under Section 5.2(b) will not occur until the date (the "Adjustment
Date") that is ninety (90) days from the Contribution Date. During this 90-day
period, the Non-Contributing Member will have the right to make a Capital
Contribution equal to the amount originally requested of the Non-Contributing
Member. If the Non-Contributing Member makes such a Capital Contribution, (i)
the Ownership Interests will not be adjusted as a result of the Capital Call
related to such Contribution Date and (ii) the Company will distribute to the
Contributing Member(s) that made Shortfall Contributions (if any) an amount
equal to the Shortfall Contribution such Contributing Member made.

      5.3 Issuance of Additional Membership Interests. If there is a
Non-Contributing Member with respect to any Capital Call (unless such
Non-Contributing Member executes its rights under Section 5.2(c)), the
Contributing Members will be issued additional Membership Interests on the
Adjustment Date in an amount, determined by the Managers, necessary to cause the
Ownership Interests to be proportional to the FMV Capital Accounts.

      5.4 Catch-up Rights. If an adjustment of Ownership Interests occurs under
Section 5.2(b) (a "Dilution") (and not as a result of the application of this
Section 5.4) (the date of such adjustment being referred to as the "Dilution
Date"), the party whose Ownership Interest was reduced in the Dilution will have
the right, subject to this Section 5.4, for a period ending one (1) year from
the Dilution Date, to make Capital Contributions to the Company sufficient to
reverse the Dilution (based on the Members' respective FMV Capital Accounts). If
any Member makes a Capital Contribution under this Section 5.4, such Member will
be issued additional Membership Interests, effective as of the date of such
Capital Contribution, sufficient to reverse the Dilution. No Member will have
any rights under this Section 5.4 if, after a Dilution Date, such Member either
(i) has less than 40% Ownership Interest or (ii) has greater than 50% Ownership
Interest.

      5.5 Return of Contributions. A Member is not entitled to the return of any
part of its Capital Contributions or to be paid interest in respect of either
its Capital Account or its Capital Contributions. An unrepaid Capital
Contribution is not a liability of the Company or of any Member. A Member is not
required to contribute or to lend any cash or property to the Company to enable
the Company to return any Member's(s') Capital Contributions.

      5.6 Advances by Members. If the Company does not have sufficient cash to
pay its obligations reasonably timely, any Member that may agree to do so with
the Managers' consent may advance all or part of the needed funds to or on
behalf of the Company. An advance described in this Section 5.6 constitutes a
loan from the Member to the Company, bears interest at the General Interest Rate
from the date of the advance until the date of payment, and is not a Capital
Contribution.

      5.7 Capital Accounts.

            (a) A Capital Account shall be established and maintained for each
Member in accordance with the rules set forth in Treas.
Reg,ss.1.704-1(b)(2)(iv).

            (b) If any additional Membership Interests are to be issued in
consideration for a contribution of property or cash or if any Company property
is to be distributed in liquidation of the Company or a Membership Interest, the
Capital Accounts of the Members (and the amounts at which all Company properties
are carried on its books and records) shall, immediately prior to the issuance
or distribution, as the case may be, be adjusted (consistent with the provisions
of section 704(b) of the Code

                                       17
<PAGE>

and the Treasury Regulations promulgated thereunder) upward or downward to
reflect any unrealized gain or unrealized loss attributable to all Company
properties (as if such unrealized gain or unrealized loss had been recognized
upon the actual sale of the properties upon a liquidation of the Company
immediately prior to the issuance). If the Carrying Value of any property of the
Company is properly reflected on the books of the Company at a value that
differs from the adjusted tax basis of such property, this Section 5.7 shall be
applied with reference to that different value.

      5.8 Special Dilution Provision.

            (a)   If

                  (i) the Managers make a Capital Call in connection with a
                  payment the Company is permitted or obligated to make under
                  the HealthFirst Purchase Agreement (including payments under
                  sections 1(c) and 8(e)-(g) of the HealthFirst Purchase
                  Agreement), and

                  (ii) a Member fails to make the Capital Contribution requested
                  of such Member in connection with a Capital Call referenced in
                  Section 5.8(a)(i),

then such Member will be diluted pursuant to Section 5.2(b); provided, however,
not apply to such dilution.

            (b)   If, during any Contribution Agreement Year,

                  (i) Baylor is diluted under Section 5.8(a) in connection with
                  a Capital Call necessary in connection with a payment the
                  Company is obligated to make pursuant to section 1(e) of the
                  HealthFirst Purchase Agreement (i.e., the HealthFirst earn-out
                  payments), and,

                  (ii) On the Reconciliation Date that concludes such
                  Contribution Agreement Year, Baylor is owed a Baylor Earn-Out
                  Amount (as shown on the Reconciliation Statement related to
                  such Contribution Year),

then, on the Reconciliation Date that concludes such Contribution Agreement ear,
Baylor must use the Baylor Earn-Out Amount to reverse Baylor's dilution (to the
extent (x) of such Baylor Earn-Out Amount and (y) necessary to reverse any
dilution occurring under Section 5.8(b) during such Contribution Agreement
Year). Such reversal will occur in accordance with Section 5.2(b) (with "USP
deemed to be the "Non-Contributing Member" with respect to the calculation
related to such reversal); provided, however, Section 5.2(c) and Section 5.4
will not apply to such reversal.

            (c)   If, during any Contribution Agreement Year,

                  (i) Baylor is diluted under Section 5.8(a) as a result of a
                  Capital Call necessary in connection with a payment the
                  Company is obligated or permitted to make pursuant to any
                  provision of the HealthFirst Purchase Agreement other than
                  Section 1(c), and

                  (ii) Baylor is credited with a Net Earn-Out Amount in the
                  Reconciliation Statement related to such Contribution
                  Agreement Year,

then, on the Reconciliation Date that concludes such Contribution Agreement
Year, Baylor must use the credit associated with such Net Earn-Out Amount to
reverse Baylor's dilution (to the extent (x) of such credit and (y) necessary to
reverse any dilution Baylor has suffered under Section 5.8(a) during such
Contribution Agreement Year). Such reversal will occur in accordance with
Section 5.2(b) (with USP

                                       18
<PAGE>

deemed to be the "Non-Contributing Member" with respect to the calculation
related to such reversal); provided, however, Section 5.2(c) and Section 5.4
will not apply to such reversal.

            (d) Any Capital Contribution made or deemed made in connection with
a Reconciliation Statement will be deemed to have been made during the
Contribution Agreement Year to which such Reconciliation Statement relates.

      5.9 Contribution Agreement. There are additional provisions in the
Agreement relating to adjustments to the Ownership Interests, which provisions
are incorporated herein by reference.

                                   Article VI

following the adjustment.

            (b) Any income, gain or loss attributable to the taxable disposition

to time pursuant to the terms hereof

            (b) From time to time, upon the approval of Managers elected by
Members with greater than 66?% Ownership Interest, the Managers may cause
property of the Company other than cash to be distributed to the Members, which

be made subject to existing liabilities and obligations. Immediately before a
distribution of non-cash property, the Capital Accounts of the Members shall be
adjusted as provided in Treas. Reg. ss. 1.704-1(b)(2)(iv)(f).

            (c) The date on which the resolution of the Managers declaring a
distribution is adopted shall be the record date for the determination of the
Members entitled to receive the distribution. The Company must give the Members
at least 10 days notice of a distribution, in accordance with Section 18.2. in
advance of any record date of such distribution; provided, however, no such
notice need be given to a Member if a Manager that Member elected votes in favor

to be prepared and filed all necessary federal and state income tax returns for
the Company. These returns will be prepared either (i) by KPMG Peat Marwick LLP
or such other accounting firm of similar national reputation that is acceptable

Company or USP employee prepares such returns, an Acceptable Firm will review
and formally indicate its approval of such returns before they are filed. Each
Member shall furnish to the Managers all pertinent information in its possession
relating to Company operations that is necessary to enable the Company's income
tax returns to be prepared and filed in a timely manner.

            (a) to adopt the year ending December 31 as the Company's fiscal
year;

best interests of the Members.

Neither the Company nor any Manager or Member may make an election for the
Company to be excluded from the application of the provisions of subchapter K of

      11.3 Tax Matters Partner." USP is hereby designated as the Tax Matters
Partner. The Tax Matters Partner shall take such action as may be necessary to
cause Baylor to become a "notice partner" within the meaning of section 6223 of
the Code. USP shall inform the Members of all significant matters that may come
to its attention in its capacity as "tax matters partner" by giving notice
thereof on or before the 30th Business Day after becoming aware thereof and,
within that time, shall forward copies of all significant written communications
it may receive in that capacity. The Tax Matters Partner may take any action
contemplated by sections 6222 through 6232 of the Code, but this sentence does
not authorize USP to take any action left to the determination of an individual
Member under sections 6222 through 6232 of the Code.

                                  Article XII
                   BOOKS, RECORDS, REPORTS AND BANK ACCOUNTS

      12.1 Maintenance of Books. The Company shall keep books and records of
accounts and shall keep minutes of the proceedings of its Members, its Managers
and each committee of the Managers. The books of accounts for the Company shall
be maintained on an accrual basis in accordance with the terms of these
Regulations, except that the capital accounts of the Members shall be maintained
in accordance with Section 5.7. The year ending December 31 shall be the
accounting year of the Company.

      12.2 Reports. On or before the seventy-fifth (75th) day following the end
of each fiscal year during the term of the Company, the Managers shall cause
each Member to be furnished with the following:

            (a) For the Company, audited (unless the Managers elect otherwise)
(by an Acceptable Firm) balance sheet and statement of operations, Members'
equity and changes in financial position, all of which shall be prepared in
accordance with accounting principles generally employed for accrual-basis
records consistently applied (except as therein noted). Subject to the next
sentence, for any audit of financial statements relating to fiscal years ending
after January 1, 2000, if the Company must pay an Acceptable Firm a fee that
exceeds twenty-thousand dollars ($20,000) for such audit, Baylor, rather than
the Company, will pay the amount of such fee that exceeds twenty-thousand
dollars ($20,000). Baylor will not be obligated to pay such excess for any
fiscal year if (i) a Baylor Manager voted against the Company doing an audit for
that fiscal year and (ii) no Baylor Manager voted in favor of the Company doing
an audit for that fiscal year.

            (b) For each Subsidiary, unaudited balance sheet and statement of
operations, members' or stockholders' or partners' (as applicable) equity, and
changes in financial position, all of which shall be prepared in accordance with
accounting principles generally employed for accrual-basis records consistently
applied (except as therein noted). The Managers may, in their discretion, cause
such financial statements to be audited by an Acceptable Firm.

            (c) (i) U.S. federal income tax Form K-1 and any similar forms
required by any state or local taxing authority and (ii) any other information
concerning the Company reasonably necessary for the preparation of the Members'
federal and state income tax returns.

            Upon showing good cause (which shall be determined without regard to
the foreseeability of such cause), the Managers shall be entitled to a
reasonable extension of the 75-day period applicable to the items described in
Section 12.2(b). The Managers also may cause to be prepared or delivered such
other reports as they may deem appropriate. The Company shall bear the costs of
all these reports.

      12.3 Accounts. The Managers shall establish and maintain one or more
separate bank and investment accounts and arrangements for Company funds in the
Company name with financial institutions and firms that the Managers determine.
The Managers may not commingle the Company's funds with the

                                       30
<PAGE>

funds of any Member; provided, however, subject to Section 7.2 and Section 3.6.
Company funds may be invested in a manner the same as or similar to the
Managers' investment of their own funds or investments by their Affiliates.

                                  Article XIII
                    DISSOLUTION, LIQUIDATION AND TERMINATION

wound up on the first to occur of the following (each, an "Event of
Dissolution"):

            (a) subject to Section 3.6, the written consent of the Members;

            (b) an entry of a decree of judicial dissolution of the Company
under article 6.02 of the Act;

            (c) the determination by Baylor or the Managers (in reliance on the
advice of legal counsel) under Section 15.5 that the ownership of a Membership
Interest in the Company by one or more Members or the referrals, items or
services furnished, or business otherwise generated from the Members has caused
the violation of a law to occur or has caused the risk that a violation of a law
will occur, and Baylor's or the Managers decision not to cause the Company to
purchase such Member's Membership Interest in accordance with Section 15.5;

            (d) At Baylor's option, if. (i) before the USP IPO Date, a Baylor
Competitor becomes able, directly or indirectly, to elect a majority of the
board of directors or similar governing body of UP, USP Parent or any Person of
which USP is a Subsidiary, (ii) after the USP IPO Date, a Baylor Competitor
becomes the Beneficial Owner of more than 25% of the outstanding voting
securities of USP, USP Parent or any Person of which USP is a Subsidiary or,
(iii) at any time, UP, USP Parent, any Restricted Affiliate of USP Parent or any
Person of which USP is a Subsidiary becomes a Baylor Competitor;

            (e) After notice to the Company in accordance with Section 18.2 and
a 30-day cure period, at Baylor's option, if the Company breaches Article XV;

            (f) At Baylor's option, if USP Parent dissolves or sells all or
substantially all of its assets;

            (g) If any Member declares an Unresolved Impasse in accordance with
Section 14.6, the Members are unable to resolve the Unresolved Impasse within
twenty (20) days of its declaration (the "Impasse Deadline") and, within thirty
(30) days after the Impasse Deadline, any Member gives notice to the Company in
accordance with Section 18.2 that the Company should be dissolved; or

            (h) Any other event causing or requiring the Company's dissolution
under the Act.

      13.2 Liquidation and Termination. On occurrence of an Event of
Dissolution, the Managers shall act as liquidator or may appoint a liquidator.
The liquidator shall proceed diligently to wind up the affairs of the Company
and make final distributions as provided herein and in the Act. The costs of
liquidation shall be borne as a Company expense. Until final distribution, the
liquidator shall continue to operate the Company properties with all of the
power and authority of the Managers. The steps to be accomplished by the
liquidator are as follows:

            (a) As promptly as possible after an Event of Dissolution, the
liquidator shall cause the Company to offer to Baylor all interests (the "Baylor
Interests") the Company directly or indirectly owns in all ambulatory surgery
centers or other outpatient centers located On or Adjacent to the Campus of a
Baylor

                                       31
<PAGE>

Hospital or Similar Facility (including interests in the relevant management
contracts) at the Fair Price of the Baylor Interests (to be determined by Baylor
and USP pursuant to Section 17.3).

            (b) If necessary, as promptly as possible after an Event of
Dissolution, the liquidator, USP and Baylor will cooperate pursuant to Section
17.3 to appraise the interests the Company owns other than Baylor Interests
(including interests in the relevant management contracts) (the "Other
Interests," and, with the Baylor Interests, the "ASC Interests"). Baylor or USP
may offer to purchase the Other Interests from the Company at a price equal to
or higher than the Fair Price of the Other Interests (determined under Section
17.3). If Baylor does not purchase all of the Baylor Interests, USP may offer to
purchase the remaining Baylor interests at a price equal to or higher than the
Fair Price of the Baylor Interests. Subject to Section 13.2(a), if Baylor or USP
offers a price higher than or equal to the Fair Price of an ASC Interest, the
liquidator will cause the Company to sell such ASC Interest to the higher
bidder. If neither Baylor or USP offers a price for an ASC Interest that is
equal to or higher than the Fair Price of such ASC Interest, the liquidator will
market the Centers to third parties and will sell the ASC Interests at the
highest available price; provided however, that Baylor and USP shall each have
the opportunity to match or exceed the highest third-party bid, and, in the
event Baylor's or USP's bid for an ASC Interest is equal to a third-party bid,
the liquidator will sell such ASC Interest to Baylor or USP. The liquidator
will, at a minimum, observe commercially reasonable standards when marketing the
Centers to third parties.

            (c) As promptly as possible after an Event of Dissolution and again
after final liquidation, the liquidator shall cause a proper accounting to be
made by an Acceptable Firm of the Company's assets, liabilities and operations
through the last day of the calendar month in which the dissolution occurs or
the final liquidation is completed, as applicable;

            (d) The liquidator shall cause the notice described in article
6.05A(2) of the Act to be mailed to each known creditor of and claimant against
the Company in the manner described in such article 6.05A(2);

            (e) The liquidator shall pay, satisfy or discharge from Company
funds all of the debts, liabilities and obligations of the Company (including
without limitation, all expenses incurred in liquidation and any advances
described in Section 5.6) or otherwise make adequate provision for payment and
discharge thereof (including, without limitation., the establishment of a cash
escrow fund for contingent liabilities in such amount and for such term as the
liquidator may reasonably determine); and

            (f)   All remaining assets of the Company shall be distributed to
the Members as follows:

                  (i) The liquidator may sell any or all Company property,
                  including to Members, and any resulting gain or loss from each
                  sale shall be computed and allocated to the Capital Accounts
                  of the Members;

                  (ii) With respect to all Company property that has not been
                  sold, the fair market value of that property shall be
                  determined and the Capital Accounts of the Members shall be
                  adjusted to reflect the manner in which the unrealized income,
                  gain, loss and deduction inherent in property that has not
                  been reflected in the Capital Accounts previously would be
                  allocated among the Members if there were a taxable
                  disposition of that property for the fair market value of that
                  property on the date of distribution; and

                  (iii) Company property shall be distributed among the Members
                  in accordance with the positive Capital Account balances of
                  the Members, as determined after taking into account all
                  Capital Account adjustments for the taxable year of the
                  Company

                                       32
<PAGE>

                  during which the liquidation occurs (other than those made by
                  reason of this clause (iii)); and those distributions shall be
                  made by the end of the taxable year of the Company during
                  which the liquidation of the Company occurs (or, if later, 90
                  days after the date of the liquidation).

All distributions in kind to the Members shall be made subject to the liability
of each distributee for costs, expenses and liabilities theretofore incurred or
for which the Company has committed prior to the date of termination and those
costs, expenses and liabilities shall be allocated to the distributee pursuant
to this Section 13.2. The distribution of cash or property to a Member in
accordance with the provisions of this Section 13.2 constitutes a complete
return to the Member of its Capital Contributions and a complete distribution to
the Member of its Membership Interest and all the Company's property. To the
extent that a Member returns funds to the Company, it has no claim against the
other Member for those funds.

      13.3 Deficit Capital Account. Notwithstanding anything to the contrary
contained in these Regulations, and notwithstanding any custom or rule of law to
the contrary, to the extent that the deficit, if any, in the Capital Account of
any Member results from or is attributable to deductions and losses of the
Company (including non-cash items such as depreciation), or distributions of
money pursuant to these Regulations to both Members in proportion to their
respective Ownership Interests, upon dissolution of the Company such deficit
shall not be an asset of the Company and such Members shall not be obligated to
contribute such amount to the Company to bring the balance of such Member's
Capital Account to zero.

      13.4 Articles of Dissolution. On completion of the distribution of Company
assets as provided herein, the Company is terminated, and the Managers (or such
other Person or Persons as the Act may require or permit) shall file articles of
dissolution with the Secretary of State of Texas and take such other actions as
may be necessary to terminate the Company.

                                  Article XIV
                                    IMPASSE

      14.1 Impasse Defined. An "Impasse" will be deemed to exist if (a) a matter
is brought to the Managers or the Members for their approval, (b) the Managers
or the Members, as the case may be, fail to approve this matter, and (c) Members
owning 20% or higher Ownership Interest authorize, in writing, a Member to give
notice of an Impasse with respect to this matter and that Member gives notice,
in accordance with Section 18.2, to the other Members and the Company that the
Member considers the failure of the Members or the Managers to approve the
matter to have caused an Impasse. An Impasse shall occur on the date the Member
gives the other Member(s) notice under this Section 14.1.

      14.2 Negotiation. In the event of an Impasse, the Members and the Company
shall promptly, amicably and in good faith attempt to resolve the Impasse
through negotiation. If the Members and the Company are unable to resolve the
Impasse within thirty (30) days of the occurrence of the Impasse (the date such
30-day period elapses is referred to as the "Mediation Initiation Date"), any
Member may submit the Impasse to mediation as set forth in Section 14.3.

      14.3 Mediation. The mediation of any Impasse hereunder shall be conducted
in accordance with the Commercial Mediation Rules and Procedures of the American
Arbitration Association ("AAA"). The Members shall attempt to agree upon an
impartial mediator to mediate the Impasse, but if they are unable or fail to
appoint a mediator within ten (10) days of the filing of a written request for
mediation with the AAA, the AAA will appoint a qualified mediator to mediate the
Impasse. The mediation shall be held in Dallas, Texas, within thirty (30) days
of appointment of the mediator. In connection with the mediation, the parties
will instruct the mediator to take into account the provisions of Article XV.

                                       33
<PAGE>

      14.4 Interim Measures. At any time after an Impasse occurs, any Member may
request a court of competent jurisdiction to grant interim measures of
protection (1) to preserve the status quo pending resolution of the Impasse, (2)
to prevent the destruction of documents and other information or things related
to the Impasse or (3) to prevent the transfer, dissipation or hiding of Company
assets. A request for such interim measures to a judicial authority shall not be
deemed incompatible with the provisions of this Article V or a waiver of a
Member's right to mediate the Impasse.

      14.5 CEO Meeting. In the event the Members and the Company are unable to
resolve the Impasse under Section 14.2 or 14.3 or the mediation does not occur
within sixty (60) days of the Mediation Initiation Date, any Member that has
made a good faith effort to comply with Sections 14.2 and 14.3 (which good faith
cannot be shown unless a written request for mediation has been filed with the
AAA) may, by written notice to the Company and the other Members in accordance
with Section 18.2, convene a meeting (a "CEO Meeting") to resolve the Impasse
between Donald E. Steen and Boone Powell, Jr., or their respective successors as
chief executive officers (or individuals serving in a similar capacity) of USP
Parent and BRCS.

      14.6 Unresolved Impasse. In the event (i) the Members and the Company are
unable to resolve the Impasse under Section 14.2, 14.3 or 14.5 or (ii) a Member
has convened a CEO Meeting under Section 14.5 and the CEO Meeting did not occur
within sixty (60) days of the date the Member sends notice to the other Member
to convene the CEO Meeting, any Member that has made a good faith effort to
comply with Sections 14.2, 14.3 and 14.5 (which good faith can not be shown
unless a written request for mediation has been filed with the AAA and a notice
convening a CEO Meeting has been sent) may, by written notice to the Company and
the other Members in accordance with Section 18.2, declare an unresolved impasse
(an "Unresolved Impasse"); provided, however, that no Member may declare a
Unresolved Impasse with respect to an Impasse unless the Impasse concerns an
issue listed in Section 14.7. An Unresolved Impasse may become an Event of
Dissolution under Section 13.1(x). The right under this Section 14.6 to declare
an Unresolved Impasse related to an Impasse will expire if the Impasse is
resolved before a Member declares an Unresolved Impasse related to the Impasse.

      14.7 Impasse Issues. A Member may declare an Unresolved Impasse only with
respect to an Impasse concerning one or more of the following items.

            (a) whether to sell, alienate, mortgage, pledge or otherwise
encumber all or substantially all of the assets of the Company or the rights
belonging thereto or connected therewith;

            (b) whether to renew any management or development contract between
the Company and USP or Baylor-,

            (c) whether to merge or consolidate with any Person; or

United States Code, as amended or recodified from time to time, or under any
similar or other law relating to bankruptcy, insolvency, reorganization or other
relief, or appoint a receiver for or liquidator of or for any part of the assets
or property of the Company or make a general assignment for the benefit of
creditors of the Company.

                                   Article XV
                              COMPLIANCE WITH LAW

      15.1 Corporate Practice of Medicine. Nothing contained in these
Regulations is intended to constitute the use of a medical license for the
practice of medicine by anyone other than a licensed

                                       34
<PAGE>

      15.2 Fraud and Abuse Law and Texas Health and Safety Code. The Members
enter into these Regulations with the intent of conducting the relationship in
full compliance with applicable state, local and federal law, including, but not
limited to, the Health Laws. Notwithstanding any unanticipated effect of any of
the provisions hereof, no Member or any Manager or other Person acting for or on
behalf of the Company will intentionally conduct itself under the terms of these
Regulations in a manner that constitutes a violation of the Health Laws.

      15.3 Referral Policy. Nothing contained in these Regulations shall require
(directly or indirectly, explicitly or implicitly) any Member to refer or direct
any patients or other business to the Company or to use the Company's
facility(ies) as a pre-condition to receiving the benefits set forth herein or
distributions under these Regulations nor will the assumption that requirement
exists be used in establishing the valuation of a Membership Interest.

      15.4 Tax Exempt .Status of Affiliate. For so long as an organization mated
with the Company is tax-exempt under section 501(c)(3) of the Code, the health
care facilities in which the Company directly or indirectly own an interest
shall be operated and managed in a manner that furthers charitable purposes by
promoting health for a broad cross section of the community. Specifically, the
Company and such health care facility shall be operated and managed in a manner:

            (a) That provides access to patient care services based on medical
necessity, without regard to the patient's ability to pay;

            (b) That provides access to patient care services to individuals
covered by Medicare or Medicaid;

            (c) That will not, in the reasonable opinion of the tax-exempt
organization on advice of the tax-exempt organization's legal and/or tax
counsel, cause such affiliated tax-exempt organization to act other than
exclusively in furtherance of its tax-exempt purposes or adversely affect its
tax-exempt status under section 501(e)(3) of the Code; or

            (d) That would not require such facility to offer or provide
services of a nature that are contrary to the expressed religious tenets of the
tax-exempt organization upon request.

      The duty of the Managers to operate and manage such health care facilities
in a manner that furthers charitable purposes by promoting health for a broad
cross section of the community overrides any duty the Managers may have to
operate and manage such health care facilities for the financial benefit of its
owners.

      The Company shall cause the organizational documents of all Subsidiaries
to include a provision similar to this Section 15.4.

      15.5 Reformation Upon Change in or Violation of Health Laws.

            (a) Reformation. In the event that the contents or validity of these
Regulations or the operations of the Company or any of its Subsidiaries are
successfully challenged by any governmental authority under applicable law,
particularly a Health Law, or any Member determines, based upon advice received
from legal counsel, that a violation of a Health Law has occurred as a result of
these Regulations or the operations of the Company or any of its Subsidiaries,
or that a violation of a law, particularly a Health Law, will occur as a result
of these Regulations or the operations of the Company or any of its

                                       35
<PAGE>

Subsidiaries, the Person who learns of a challenge by a governmental authority
of the contents or validity of these Regulations or the operations of the
Company or any of its Subsidiaries or the Member that determines that a
violation of a law has occurred or may occur, as applicable, shall promptly
notify the Members and the Managers. The Managers shall promptly use reasonable
efforts to analyze, revise, reform and, to the extent necessary, restructure the
relationship among the Members or the operations of the Company or any of its
Subsidiaries in order to fully comply with applicable law in a manner that is
equitable to all Members in light of the intent of the Members regarding the
operations of the Company and its Subsidiaries as contemplated by these
Regulations. The Managers shall recommend its reformation plan for accomplishing
the desired results to the Members for approval. As long as Baylor is a Member,
unless Baylor approves a reformation plan, a reformation plan will not be deemed
to be approved by the Members.

            (b) Failure to Reform. In the event the Managers are unable to
formulate a plan to revise, reform and restructure these Regulations and the
operations of the Company and its Subsidiaries in order to fully comply with all
applicable laws or the reformation plan fails to receive the necessary
affirmative vote of the Members, the Managers will do as follows: if Baylor
determines in good faith that it is the ownership of a Membership Interest in
the Company by one or more of the Member(s) other than Baylor or the referrals,
items or services furnished, or business otherwise generated from such Members
that has caused the violation of a law to occur or that has caused the risk that
a violation of a law will occur, Baylor may, at its option, direct the Managers
to (A) cause the Company to purchase the Membership Interest(s) of one or more
of such Members at a purchase price equal to the Fair Market Value of such
Member's(s) Membership Interest calculated in accordance with Section 4.2(c); or
(B) cause the Company to be dissolved in accordance with Article XIII; or if
Baylor determines in good faith that it is the ownership of a Membership
Interest in the Company by Baylor that has caused the violation of a Health Law
to occur or that has caused the risk that a violation of a law will occur and
Baylor gives the other Member(s) written notice of its determination to that
effect (the "Determination Notice"), then Baylor may direct the Managers to
cause the Company to be dissolved in accordance with Article III hereof.

      15.6 ASC Operating Covenants. The Company will cause all ambulatory
surgery centers in which the Company owns a direct or indirect interest (the
"ASCs") to operate in accordance with the following guidelines:

            (a) Baylor will have the right to approve the medical director of
each AC located On or Adjacent to the Campus of a Baylor Hospital or Similar
Facility.

            (b) Standards of quality patient care at the ASC will be
commensurable with the standards of quality patient care at BHCS.

            (c) Each ASC will have a conflict-of-interest policy acceptable to
Baylor.

            (d) Each ASC will have a charity care, Medicare and Medicaid policy
acceptable to Baylor and

            (e) Physician credentialing for the ASCs must meet or exceed NCQA
requirements.

            (f) The ASCs must follow Baylor's policies in effect from time to
time regarding prohibited medical procedures (for example abortions).

            (g) The ASCs must maintain all necessary licenses and must maintain
accreditation in good standing with JCAHO or ABC, or comparable accrediting
organizations for free standing and ambulatory surgery centers.

                                       36
<PAGE>

            (h) If an ASC is On or Adjacent to the Campus of a Baylor Hospital
or Similar Facility affiliated with Baylor, that ASC's medical staff bylaws must
require that physicians be on staff with such Hospital or Similar Facility or in
the process of being admitted on staff before joining the staff of the ASC,
except as otherwise agreed by USP and Baylor in consultation with such ASC's
medical director.

                                  Article XVI
                       RIGHT OF FIRST REFUSAL/EXCLUSIVITY

      16.1 Initial Notice. As more fully described in this Article XVI. the
Company will have a right of first refusal on all ambulatory surgery center
projects within the North Texas Region in which any Member or Restricted Person
(as defined in this Section 16.1) proposes to participate. The parties intend
for the Company's right of first refusal to be subject to and secondary in right
to the right of first refusal included in article XVI of the THVG #1
regulations. Subject to Section 16.2, before a Member, UP Parent (or any
Restricted Affiliate of USP Parent) or BHC(or Person that is, as of the date of
these Regulations, an existing Restricted Affiliate of BHCS) (collectively, the
"Restricted Persons") may participate in a Venture in the North Texas Region,
the Member affiliated with the Restricted Person (the "Proposing Member") must
first give the Company and the other Members a notice, in accordance with
Section 18.2, that describes in reasonable detail sufficient to male an informed
decision the Venture and the proposed participation therein (the "Initial
Notice"). No Member will be deemed to be a Proposing Member with respect to a
Venture unless such Member has given an Initial Notice regarding such Venture.
Any initial notice USP gives under article XVI of the THVG 4 1 regulations will
constitute an Initial Notice under this Section 16.1. No Member may propose a
Venture to the Company unless such Member has previously been deemed to be a
"proposing member" with respect to such Venture under article XVI of the THVG #1
regulations.

      16.2 USP and BIAS Carve-outs. This Article XVI does not apply to Ventures
related to ambulatory surgery centers in which the entire interest of each
Member is owned through THVG #1 or any of its Subsidiaries. This Article XVI
does not apply to the participation of Baylor and any Restricted Person
affiliated with Baylor in Ventures related to ambulatory surgery centers that
are located tin or Adjacent to the Campus of a Baylor Hospital or Similar
Facility. After the closing of the proposed transaction or affiliation among
BRCS and one or more of Harris Methodist Health System, Presbyterian Healthcare
Resources and Arlington Memorial Hospital Foundation, Inc., BHCS and all
Southwest Health System Entities (other than existing Restricted Affiliates of
BHCS as of the date of these Regulations) will not be subject to this Article
XVI. After the date of such closing, without first complying with this Article
XVI, USP, USP Parent or any Restricted Affiliate of USP Parent may participate
in Ventures related to an ambulatory surgery center if any Southwest Health
System Entity (other than the Company, THVG # 1 and their Subsidiaries) owns a
direct interest in that ambulatory surgery center.

      16.3 Company Response; Restrictions on Participation.

            (a) Within sixty (60) days of receipt of an Initial Notice (the
"Response Period"), the Company will elect, if so directed by all Members other
than the Proposing Member by written notice given in accordance with Section
18.2 (the "Company Response"), to participate in the Venture that is the subject
of such Initial Notice.

            (b) If the Company elects to participate in such Venture, subject to
Section 16.2, no Restricted Person may participate in such Venture without
approval of all of the Members. Subject to Sections 16.5 and 16.7, if all other
Member(s) give notice to the Proposing Member that such Member(s) will not cause
the Company to give a Company Response, or if the Company does not send a
Company Response within the Response Period, the Proposing Member and the
Restricted Persons affiliated with the Proposing Member may participate in such
Venture so long as the terms of such Venture are not materially more favorable
than the terms described in the Initial Notice and the Proposing Member provides
a

                                       37
<PAGE>

certificate to this effect, executed by an executive officer of the Proposing
Member, and, in the case of USP, the USP Parent, to the Company.

            (c) If USP proposes a Venture to THVG #1 and THVG #1 chooses not to
participate in such Venture, USP must propose such Venture to the Company
pursuant to this Article XVI.

            (d) If Baylor proposes a Venture to THVG #1, THVG #1 chooses not to
participate in such Venture and such Venture is not related to an ambulatory
surgery center located (in or Adjacent to the Campus of a Baylor Hospital or
Similar Facility, Baylor must propose such Venture to the Company pursuant to
this Article XVI. Baylor need not propose such Venture to the Company if such
Venture is related to an ambulatory surgery center located On or Adjacent to the
Campus of a Baylor Hospital or Similar Facility.

      16.4 Breaches by Affiliates. Subject to Section 16.2, if a Restricted
Person affiliated with a Member breaches this Article XVI, that Member will be
deemed to have breached this Article XVI.

      16.5 Material Changes. If any significant detail of a Venture materially
changes after a Member gives an Initial Notice describing such Venture, and such
change would reasonably be expected to affect a decision whether to participate
in such Venture, a Member must again comply with this Article XVI before such
Member or any Restricted Person mated with such Member may participate in such
Venture

      16.6 Carve-Out and Termination. This Article XVI will not apply to (i) a
Venture of BHCS or a Person that is, as of the date of these Regulations, an
existing Restricted Affiliate of BHCS or (ii) the participation of BHCS or such
Person in such Venture if, in either case, in the reasonable opinion of BHCS's
or such Person's national health care or tax counsel (which at the request of UP
shall be a nationally-recognized law firm with expertise in the field of
tax-exempt organizations that does not regularly represent Baylor or its
Affiliates), the application of this Article 2M, or the Company's participation
in such Venture, would result in a violation of Health Laws or adversely affect
the tax-exempt status of BHCS or such Person. In the event BHCS or such Person
obtains such an opinion, this Article XVI will terminate and be of no force and
effect as of the date of such opinion, unless both UP and Baylor waive this
provision in writing. This Article XVI will terminate and be of no force and
effect as of the earlier to occur of the following: (x) either Baylor or USP
cease to own Membership Interest or (y) either Baylor or USP (A) terminates
article XVI of the THVG #1 regulations in accordance with the last sentence of
section 16.6 of the THVG #1 regulations and, (B) within sixty (60) days of such
termination, gives the other Member(s) and the Company notice, in accordance
with Section 18.2, that Article XVI of these Regulations is also terminating.

      16.7 Baylor Campus Restriction. USP and the Restricted Persons affiliated
with USP may not participate in a Venture related to an ambulatory surgery
center located Can or Adjacent to the Campus of a Baylor Hospital without
Baylor's consent.

      16.8 Goad Faith Requirement. Each Member will use good faith efforts to
cause the terms of each Venture such Member proposes to the Company to be such
that, if the Company elects to participate in such Venture, such participation
will not violate these Regulations.

                                  Article XVII
                          INTERESTS IN SURGERY CENTERS

      17.1 Baylor Right of First Refusal. Without Baylor's written consent,
before the Company may Dispose of any Baylor Interest, (i) the Company must
first offer to sell Baylor such Baylor Interest (the

                                       38
<PAGE>

"First Refusal Offer") at the Fair Price of the Baylor Interest (to be
determined by Baylor and USP in accordance with Section 17.3) and (ii) Baylor
must reject the First Refusal Offer.

      17.2 Membership Interest Transfer. On the occurrence of any event that
causes Baylor to cease to own a 20% or higher Ownership Interest, the Company
must offer to sell Baylor the Baylor Interests (the "Baylor Offer") at the Fair
Price of the Baylor Interests (to be determined by Baylor and UP in accordance
with Section 17.3). Baylor will have an option expiring ninety (90) days from
the determination of the Fair Price of Baylor Interests to purchase the Baylor
Interests from the Company.

      17.3 Fair Price of the ASC Interests. For purposes of this Agreement,
including this Article XVII and Section 13.2 the "Fair Price" of ASC Interests
(including Baylor Interests) will be determined as follows:

      A qualified appraiser agreed upon by Baylor and USP will determine the
Fair Price of the relevant AC Interests. If Baylor and USP cannot agree on an
appraiser within thirty (30) days of (i) the notice delivering a First Refusal
Offer under Section 17.1, (ii) the notice delivering a Baylor Offer under
Section 17.2 or (iii) an Event of Dissolution, as applicable, Baylor will name
one qualified appraiser and USP will name one qualified appraiser, in each case
by notice delivered in accordance with Section 18.2 to the other party, within
ten (10) days after such 30-day period elapses. If only one party delivers the
name of a qualified appraiser within such 10-day period, then such appraiser
shall be deemed to be the agreed upon appraiser for purposes of this Section
17.3. If both Baylor and USP name a qualified appraiser in accordance with this
Section 17.3. these appraisers shall select a third appraiser and all three
appraisers shall independently and promptly appraise the Pair Price of the ASC
Interests and deliver written reports of such appraisals to all parties. These
appraisals shall be averaged, the appraisal that differs most from the average
shall be disregarded, and the average of the remaining appraisals shall be the
Fair Price of the ASC Interests for purposes of this Section 17.3. If one
appraiser is used under this Section 17.3, then Baylor will pay one-half (1/2)
of appraisal cost and USP will pay one-half (1/2) of the appraisal cost, If more
than one appraiser is used under this Section 17.3, then each party will pay the
cost of the appraiser it selects and one-half (1/2) of the cost of the third
appraiser.

                                 Article XVIII
                               GENERAL PROVISIONS

      18.1 Offset. Whenever the Company is to pay any sum to a Member, any
amounts that Member owes the Company may be deducted from that sum before
payment.

      Any notice, request or consent to the Company must be given to both of the
following addresses:

                             USP North Texas, Inc.

              Executive Vice President and Chief Operating Officer

Whenever any notice is required to be given by law, the Articles of Organization
or these Regulations, a written waiver thereof, signed by the Person entitled to
notice, whether before or after the time stated therein, shall be deemed
equivalent to the giving of such notice.

      18.3 Entire Agreement; Supersedure. Subject to the provisions of these
Regulations that reference or incorporate other documents or agreements, these
Regulations constitute the entire agreement of the Members relating to
governance of the Company and supersede all prior contracts or agreements with
respect to the governance of Company, whether oral or written.

      18.4 Effect of Waiver or Consent. A waiver or consent, express or implied,
to or of any breach or default by any Person in the performance by that Person
of its obligations with respect to the Company is not a consent or waiver to or
of any other breach or default in the performance by that Person of the same or
any other obligations of that Person with respect to the Company. Failure on the
part of a Person to complain of any act of any Person or to declare any Person
in default with respect to the Company, irrespective of how long that failure
continues, does not constitute a waiver by that Person of its rights with
respect to that default until the applicable statute of limitations period has
run.

      18.5 Amendment or Modification. These Regulations maybe amended or
modified from time to time only by a written instrument approved by Baylor and
USP; provided, however, if either Baylor or USP ceases to be a Member of the
Company, its approval will not be necessary to amend these Regulations.

assigns.

      18.7 Governing Law; Severability. THESE REGULATIONSARE GOVERNED BY AND
SHALL HE CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF TEXAS, EXCLUDING
ANY CONFLICT-Off'-LAWS RULE OR PRINCIPLE THAT MIGHT REFER THE GOVERNANCE OR THE
CONSTRUCTION OF THESE REGULATIONS TO THE LAW OF ANOTHER JURISDICTION. In the
event of a direct conflict between the provisions of these Regulations and (a)
any provision of the Articles of Organization or (b) any mandatory provision of
the Act or, to the extent such statutes are incorporated into the Act, the TBCA
or the Texas Miscellaneous Corporation Laws Act, the applicable provision of the
Articles of Organization, the Act, the TBCA or the Texas Miscellaneous
Corporation Laws Act shall control. If any provision of these Regulations or the
application thereof to any Person or circumstance is held invalid or
unenforceable to any extent, the remainder of these Regulations and the
application of that provision to other Persons or circumstances root affected
thereby and that provision shall be enforced to the greatest extent permitted by
law.

      18.8 Further Assurances. In connection with these Regulations and the
transactions contemplated hereby, each Member shall execute and deliver any
additional documents and instruments and perform any additional acts that may be
necessary or appropriate to effectuate and perform the provisions of these
Regulations and those transactions.

      18.9 Waiver of Certain Rights. Subject to Article MR, each Member
irrevocably waives any right it may have to maintain any action for dissolution
of the Company or for partition of the property of the Company.

      18.10 Notice to Members of Provisions of this Agreement. By executing
these Regulations, each Member acknowledges that it has actual notice of (a) all
of the provisions of this Agreement, including, without limitation, the
restrictions on the transfer of Membership Interests set forth in Article IV

                  UNITED SURGICAL PARTNERS INTERNATIONAL, INC.

                    Convertible Subordinated Promissory Note

        $3,287,234                                            June 1, 1999

            UNITED SURGICAL PARTNERS INTERNATIONAL, INC., a Delaware corporation
(hereinafter called the "Corporation"), for value received, hereby promises to
pay to Baylor Health Services, a Texas non-profit corporation, the principal sum
of Three Million Two Hundred Eighty Seven Thousand Two Hundred Thirty Four
Dollars ($3,287,234) on June 1, 2007 (subject to applicable restrictions set
forth in Section 12 hereof), and to pay interest (computed on the basis of a
365-day year) from the date hereof on the unpaid principal amount hereof at the
rate of __ per annum, payable quarterly in arrears on the first day of January,
April, July and October of each year (each said day being an "Interest Payment
Date"), commencing on July 1, 1999, and until the date the outstanding principal
amount hereof shall have become due and payable in full, whether at maturity or
by acceleration or otherwise. If the principal amount hereof shall not be paid
when the same shall have become due and payable in full, whether at maturity or
by acceleration or otherwise, then such overdue principal amount and (to the
extent permitted by applicable law) any overdue interest shall thereupon bear
interest until paid in full at a floating rate per annum equal to the lesser of
(a) 2% plus the "prime rate" from time to time published in the Wall Street
Journal or (b) the maximum rate permitted under applicable law, as and when
amended from time to time.

            All payments of principal and interest on this Convertible
Subordinated Promissory Note ("Note") shall be in such coin or currency of the
United States of America as at the time of payment shall be legal tender for
payment of public and

                                       1
<PAGE>

private debts, and shall be made at the offices of the person deemed the holder
hereof in accordance with Section 4 below.

            1. Conversion of the Note.

                  (a) The holder of this Note shall have the right, at such
holder's option, at any time to convert, subject to the terms and provisions of
this Section 1, the principal of this Note or any portion hereof into shares of
Class A Common Stock, par value $.01 per share (the "Common Stock"), of the
Corporation at a price of $3.50 per share or, in case of an adjustment of such
price has taken place pursuant to the provisions of paragraph (d) below, then at
the price as last adjusted (referred to herein as the "Conversion Price"), upon
surrender of the Note to the Corporation at any time during normal business
hours together with written notice (hereinafter referred to as the "Conversion
Notice") that the holder elects to convert this Note into such Common Stock in
accordance with the provisions of this Section 1, and specifying the name or
names in which the shares of stock issuable upon conversion shall be registered,
together with the addresses of the persons so named, and, if any such name is
different from the holder's name, shall be accompanied by a written instrument
or instruments of transfer in form satisfactory to the Corporation duly executed
by the registered holder and the documents described in Section 2. Upon
surrender of any Note which is to be converted in part only, the Corporation
shall execute and deliver to the holder thereof, at the expense of the
Corporation, a new Note in principal amount equal to the unconverted portion of
the Note so surrendered.

                  (b) As promptly as practicable after the surrender, as herein
provided, of this Note for conversion and the receipt of the Conversion Notice
relating thereto, the Corporation shall deliver to or upon the written order of
the holder of the Note so surrendered certificates representing the number of
fully paid and non-assessable shares of Common Stock of the Corporation into
which this Note may be converted in accordance with the provisions of this
Section 1 and a new Note for any unconverted portion of the principal amount.
Such conversion shall be deemed to have been made at the close of business on
the date that such Note shall have been surrendered for conversion together with
the Conversion Notice, so that the rights of the holder of the portion of this
Note that is so converted shall cease at such time (with respect to such
converted portion) and the person or persons entitled to receive the shares of
Common Stock upon conversion of such Note shall be treated for all purposes as
having become the record holder or holders of such shares of Common Stock at
such time, and such conversion shall be at the Conversion Price in effect at
such time.

                  (c) Except as provided in paragraph (d) below, no adjustments
in respect of dividends shall be made upon the conversion of any Note,

                  (d) The Conversion Price shall be adjusted as follows:

                        (i) In case the Corporation shall at any time (A) make a
subdivision of shares of Common Stock outstanding or (B) pay a dividend in
shares of Common Stock or make a distribution in shares of Common Stock. In any
such case the Conversion Price in effect immediately prior to such action shall
be proportionately decreased, and in case the Corporation shall at any time
combine the shares of Common Stock outstanding, the Conversion Price in effect
immediately prior to such combination shall be proportionately increased. An
adjustment made pursuant to this clause (i) of paragraph (d) shall, in the case
of a subdivision or combination, become effective retroactively on the effective
date thereof and shall, in the case of such a dividend or distribution, become
effective retroactively immediately on the record date for the determination of
stockholders entitled thereto.

                        (ii) In case the Corporation shall, by dividend or
otherwise, distribute to all holders of its Common Stock, or to all holders of
the Corporation's Common Stock, par value $.01 per share (the "Conversion
Common"), evidences of its indebtedness, shares of any class of capital stock
(other than Common Stock), cash or assets (including securities, but excluding
(A) any rights or warrants entitling the holders thereof to subscribe for or
purchase shares of Common Stock or other securities at a price per share less
than the fair market value thereof at the time such rights or warrants are
issued, (B) any dividend or distribution paid exclusively in cash out of the
retained earnings of the Corporation and (C) any dividend or distribution
referred to in clause (i) above). In any such case the Conversion Price shall be
reduced by multiplying the Conversion Price in effect immediately prior to the
effectiveness of such distribution by a fraction, (x) the numerator of which
shall be the current fair market price per share of the Common Stock on such
date less the fair market value of the portion of the evidences of indebtedness,
shares of capital stock, cash and assets so distributed that is directly or
indirectly applicable to one share of Common Stock, and (y) the denominator of
which shall be the current fair market price per share on such date. Any
reduction in the Conversion Price pursuant to this clause (ii) shall become
effective immediately prior to the opening of business on the day following the
date fixed for the determination of stockholders entitled to receive such
distribution.

                        (iii) In case the Corporation shall issue capital stock
at a net price per share or unit less than the fair market value per share of
such capital stock or unit on the date

                                       3
<PAGE>

the Corporation fixes the offering price of such additional shares or units. In
any such case the Conversion Price shall be reduced immediately thereafter so
that it shall be equal to the price determined by multiplying the Conversion
Price in effect immediately prior thereto by a fraction, (x) the numerator of
which shall be the number of shares of Common Stock outstanding immediately
prior to the issuance of such additional capital stock or units plus the number
of shares of Common Stock that would be purchased (at the then current fair
market value per share of the Common Stock) with the aggregate sales price of
the shares of additional capital stock or units so issued, and (y) the
denominator of which shall be the number of shares of Common Stock outstanding
immediately prior to the issuance of such additional shares or units plus the
number of shares of Common Stock that would be purchased (at the then current
fair market value per share of the Common Stock) with the aggregate sales price
that would have been received by the Corporation for such shares of additional
shares of capital stock or units if they had been offered and sold at their fair
market value, Such adjustment shall be made successively whenever such an
issuance is made. For purposes of this clause (iii) the number of shares of
stock at any time outstanding shall not include shares held in the treasury of
the Corporation, but shall include shares issuable in respect of script
certificates issued in lieu of fractions of shares of Common Stock. This clause
(iii) shall not apply to (A) Common Stock issued under bona fide benefit plans
adopted by the Board of Directors for the benefit of the Corporation's
directors, employees, consultants and advisors and, to the extent required by
law, approved by the holders of Common Stock, (B) issuances of shares of stock
upon the exercise of rights or options or the conversion of convertible
securities where the exercise price of such rights or options or the conversion
price of such convertible securities was at or above the fair market price per
share of such securities at the time such rights, options or convertible
securities were initially issued, (C) issuances of equity securities (including
options for and securities convertible into equity securities) at a price
committed to (whether such commitment is legally binding or not) in connection
with a proposed transaction where the price so committed to was at or above the
fair market price of such securities at the time of such commitment and the
securities are actually issued within six months after the date of such
commitment.

            Until such time as the Common Stock is publicly traded, the fair
market price of the Corporation's securities, and all other determinations of
fair market value required by this paragraph (d), shall be as determined by the
Board of Directors of the Corporation in good faith, which determination shall
be described in a resolution of the Board of Directors.

      (e) Whenever the Conversion Price is adjusted, pursuant to paragraph (d)
above, the Corporation shall promptly cause a notice to be given to the holder
of this Note at its

                                       4
<PAGE>

address appearing on the Note registry books, which notice will state the
adjusted Conversion Price, the number of shares of Common Stock or other
securities, cash or property issuable upon conversion of this Note resulting
from such adjustment, setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based.

      (f) No fractional shares or script representing fractional shares shall be
issued upon the conversion of this Note and, if the conversion of the Note
results in a fraction, in lieu of any such fractional share the Company shall
pay cash equal to such fraction multiplied by the then effective Conversion
Price.

      (g) In case of any reorganization, reclassification or change of
outstanding shares of Common Stock issuable upon conversion of the Notes
(including any conversion of Common Stock into the Conversion Common pursuant to
the Corporation's Certificate of Incorporation) or in case of any consolidation
or merger of the Corporation with or into another corporation (other than a
merger in which the Corporation is the continuing corporation and which does not
result in any reclassification or change of outstanding shares of Common Stock)
or in case of any sale or conveyance to another corporation of the property of
the Corporation as an entirety or substantially as an entirety, then prior to
and as a condition to any such reorganization, reclassification, consolidation,
merger or sale, lawful and adequate provision shall be made whereby the holder
of this Note shall have the right thereafter to convert this Note into the kind
and amount of shares of stock and other securities and property receivable upon
such reorganization, reclassification, change, consolidation, merger, sale or
conveyance by a holder of the number of shares of Common Stock of the
Corporation into which such Note might have been converted immediately prior to
such reorganization, reclassification, change, consolidation, merger, sale or
conveyance and in any such case appropriate provision shall be made with respect
to the rights and interest of the holder of this Note to the end that the
provisions hereof shall thereafter be applicable, as nearly as may be, in
relation to any such shares of stock, securities or assets thereafter
deliverable upon the exercise of such conversion rights. In the event of a
merger or consolidation of the Corporation as a result of which a greater or
lesser number of shares of Common Stock of the surviving corporation are
issuable to holders of Common Stock outstanding immediately prior to such merger
or consolidation, the Conversion Price shall be adjusted in the same manner as
though there were a subdivision or combination of the outstanding shares of
Common Stock of the Corporation. The Company shall not effect any such
consolidation, merger or sale unless prior to or simultaneously with the
consummation thereof the survivor or successor corporation (if other than the
Corporation) resulting from such consolidation or merger or the corporation
purchasing such assets shall assume, by written instrument executed and sent to
the

                                       5
<PAGE>

holder of this Note, the obligation to deliver to such holder shares of stock,
securities or assets as, in accordance with the foregoing provisions, such
holder may be entitled to receive, and containing the express assumption by such
successor corporation of the due and punctual performance and observance of
every provision of this Note to be performed and observed by the Corporation and
of all liabilities and obligations of the Corporation hereunder. The provisions
of this paragraph (g) shall apply to successive reorganizations,
reclassifications, consolidations, mergers and sales.

      (h) The Corporation covenants that it will at all times reserve and keep
available out of its authorized Common Stock, solely for the purpose of issuance
upon conversion of this Note as herein provided, such number of shares of Common
Stock as shall then be issuable upon the conversion of this Note. The
Corporation covenants that all shares of Common Stock which shall be so issuable
shall be duly and validly issued, fully paid and non-assessable.

      (i) The issuance of certificates for shares of Common Stock upon the
conversion of this Note shall be made without charge to the converting holder
for any tax in respect of the issuance of such certificates; provided, however,
that the Corporation shall not be required to pay any tax which may be payable
in respect of any transfer involved in the issuance and delivery of any such
certificate in a name other than that of the holder of the Note converted.

      (j) In the event that this Note is assigned, the provisions of this
Section 1 shall terminate and be of no further force or effect, but the
termination of this Section 1 shall not affect the other obligations of the
Corporation under this Note; provided, however that this paragraph (j) shall not
apply to an assignment to Baylor Health Care System Foundation or to any party
to which the initial holder is entitled to assign its membership interest in
Texas Health Ventures Group L.L.C. pursuant to the terms of said entity's Second
Amended and Restated Regulations, dated as of June 1, 1999 (as hereinafter
amended).

      (k) The Corporation will at no time close its transfer books against the
transfer of any Common Stock or any other securities issued or issuable upon the
conversion of this Note in any manner which interferes with the timely
conversion of this Note.

      (l) So long as this Note is outstanding, the Corporation shall give to the
holder of this Note written notice at. least 15 days prior to the proposed
record or effective date of (i) any dividend to be paid with respect to any of
the Corporation's shares of capital stock, (ii) any proposed initial public
offering (as described in paragraph (a) in Section 5

                                       6
<PAGE>

below), and (iii) any consolidation, merger, sale of assets or similar
transaction by the Corporation with or in to another entity (other than such a
transaction in which the stockholders of the Corporation immediately prior to
such transaction own in excess of 50% of the voting capital stock of the
Corporation outstanding immediately after the effective date of such transaction
in the same proportions in which such shares were held immediately prior to such
transaction).

            2. Transfer, Etc. of Notes. The Corporation shall keep at its office
or agency maintained as provided in paragraph (a) of Section 6 a register in
which the Corporation shall provide for the registration of this Note and for
the registration of transfer and exchange of this Note. The holder of this Note
may, at its option, and either in person or by duly authorized attorney,
surrender the same for registration of transfer or exchange at the office or
agency of the Corporation maintained as provided in paragraph (a) of Section 6
and, without expense to such holder (except for transfer taxes, if any, imposed
in connection therewith), receive in exchange therefor a Note or Notes each in
such denomination or denominations as such holder may request (which
denominations shall be $100,000 or an integral multiple thereof, except for any
balance which may be less than $100,000), dated as of the date to which interest
has been paid on the Note or Notes so surrendered for transfer or exchange, for
the same aggregate principal amount as the then unpaid principal amount of the
Note or Notes so surrendered for transfer or exchange, and registered in the
name of such person or persons as may be designated by such holder, This Note,
when presented or surrendered for registration of transfer or exchange, shall be
duly endorsed, or shall be accompanied by a written instrument of transfer,
satisfactory in form to the Corporation, duly executed by the holder of such
Note or his attorney duly authorized in writing. Every Note so made and
delivered in exchange for this Note shall in all other respects be in the same
form and have the same terms as this Note. No transfer or exchange of any Note
shall be valid unless made in the foregoing manner at such office or agency.

            3. Loss, Theft, Destruction or Mutilation of Note. Upon receipt of
evidence satisfactory to the Corporation of the loss, theft, destruction or
mutilation of this Note and, in the case of any such loss, theft or destruction,
upon receipt of an affidavit of loss and indemnity from the holder hereof
reasonably satisfactory to the Corporation or, in the case of any such
mutilation, upon surrender and cancellation of this Note, the Corporation will
make and deliver, in lieu of this Note, a new Note of like tenor and unpaid
principal amount and dated as of the date to which interest has been paid on
this Note.

            4. Persons Deemed Owners; Ho1ders. The Corporation may deem and
treat the person or entity in whose name this Note

                                       7
<PAGE>

is registered as the owner and holder of this Note for the purpose of receiving
payment of principal of and interest on this Note and for all other purposes
whatsoever, whether or not this Note shall be overdue. With respect to any Note
at any time outstanding, the term "holder" as used herein shall be deemed to
mean the person or entity in whose name such Note is registered as aforesaid at
such time.

            5. Prepayments. The Corporation may prepay this Note as follows:

      (a) Mandatory Prepayment. Except as and to the extent expressly prohibited
by applicable law, the Corporation shall prepay the principal amount, plus
accrued and unpaid interest, of all Notes which shall then be outstanding upon
the consummation by the Corporation of an initial public offering of its Common
Stock, par value $.01 per share, registered under the Securities Act of 1933, as
amended.

      (b) Optional Prepayment. At any time after the occurrence of an "Event of
Dissolution" as such term is defined in the Second Amended and Restated
Regulations, dated as of June 1, 1999 of Texas Health Ventures Group L.L.C., a
Texas limited liability company, the Corporation may, at its option, prepay this
Note, without penalty, in whole or in part, by paying the principal amount to be
prepaid plus all accrued but unpaid interest thereon. If such Event of
Dissolution occurred pursuant to Section 13.1(d) of said Second Amended and
Restated Regulations (or any successor provision), the holder of this Note may,
at its option (and regardless of whether the Corporation exercises its option
pursuant to the preceding sentence), require the Corporation to prepay this
Note, without penalty, in whole or in part, by paying the principal amount to be
prepaid plus all accrued but unpaid interest thereon. Any date on which the
Corporation elects or is required to prepay any of the Notes as provided in this
paragraph (b) and each date on which the Corporation shall be required to prepay
the Notes as provide in paragraph (a) above shall be referred to as a
"Prepayment Date."

      (c) Notice of Prepayment. Not less than 30 days prior to a Prepayment
Date, written notice shall be given by registered or certified mail or by
overnight courier to the holders of record of the Notes to be prepaid, such
notice to be addressed to each such holder at his post office address as shown
by the records of the Corporation, specifying the dollar amount to be prepaid,
the paragraph or paragraphs of this Note pursuant to which such prepayment shall
be made, and the date of such prepayment, which date shall not be a day on which
the banks of New York are required or authorized to be closed. Upon notice of
prepayment being given as aforesaid, the Corporation covenants and agrees that
it will prepay, on the date therein fixed for

                                       8
<PAGE>

prepayment, this Note or the portion hereof, as the case may be, so called for
prepayment, at the prepayment price determined in accordance with paragraph (a)
or (b) above. A prepayment of less than all of the outstanding principal amount
of this Note shall not relieve the Corporation of its obligation to make
scheduled payments of interest payable in respect of the principal remaining
outstanding on the Interest Payment Dates.

      (d) Allocation of All Payments. In the event of any partial payment of
less than all of the interest then due on the Notes then outstanding or any
prepayment, purchase, redemption or retirement of less than all of the
outstanding principal amount of the Notes, the Corporation will allocate the
amount of interest so to be paid and the principal amount so to be prepaid,
purchased, redeemed or retired to each Note in proportion, as nearly as may be,
to the aggregate principal amount of all Notes then outstanding.

      (e) Interest After Date Fixed for Prepayment. If this Note or a portion
hereof is called for prepayment as herein provided, this Note or such portion
shall cease to bear interest on and after the date fixed for such prepayment
unless, upon presentation for such purpose, the Corporation shall fail to pay
this Note or such portion, as the case may be, in which event this Note or such
portion, as the case may be, and, so far as may be lawful, any overdue
installment of interest, shall bear interest on and after the date fixed for
such prepayment and until paid at the rate per annum provided herein.

      (f) Surrender of Note; Notation Thereon. Upon any prepayment of a portion
of the principal amount of this Note, the holder hereof, at its option, may
require the Corporation to execute and deliver at the expense of the Corporation
(other than for transfer taxes, if any), upon surrender of this Note, a new Note
registered in the name of such person or persons as may be designated by such
holder for the principal amount of this Note then remaining unpaid, dated as of
the date to which the interest has been paid on the principal amount of this
Note then remaining unpaid, or may present this Note to the Corporation for
notation hereon of the payment of the portion of the principal amount of this
Note so prepaid.

            6. Covenants. The Corporation covenants and agrees that, so long as
this Note shall be outstanding:

      (a) Maintenance of Office. The Corporation will maintain an office or
agency in such place in the United States of America as the Corporation may
designate in writing to the registered holder hereof, where this Note may be
presented for registration of transfer and exchange as herein provided, where

                                       9
<PAGE>

notices and demands to or upon the Corporation in respect of this Note may be
served and where, at the option of the holder thereof, this Note may be
presented for payment. Until the Corporation otherwise notifies the holder of
this Note, said office shall be the principal office of the Corporation at 17103
Preston Road, Suite 190 North, Dallas, Texas 75248,

      (b) Corporate Existence. The Corporation will do or cause to be done all
things necessary and lawful to preserve and keep in full force and effect its
corporate existence, rights and franchises and the corporate or partnership
existence, rights and franchises of each of its subsidiaries; provided, however,
that nothing in this paragraph (b) shall prevent (1) a consolidation or merger
of, or a sale, transfer or disposition of all or any substantial part of the
property and assets of, the Corporation or (ii) the abandonment or termination
of any rights or franchises of the Corporation, or the liquidation or
dissolution of, or a sale, transfer or disposition (whether through merger,
consolidation, sale or otherwise) of all or any substantial part of the property
and assets of, any subsidiary or the abandonment or termination of the corporate
or partnership existence, rights and franchises of any subsidiary if such
abandonment, termination, liquidation, dissolution, sale, transfer or
disposition is, in the good faith business judgment of the Corporation, in the
best interests of the Corporation and is not disadvantageous in any material
respect to the holder of this Note.

      (c) Notice of Default. If any one or more events which constitute, or
which with notice or lapse of time or both would constitute, an Event of Default
under Section 8 of this Note shall occur, or if any holder of the Notes shall
demand payment or take any other action permitted upon the occurrence of any
such Event of Default, the Corporation shall, immediately after it becomes aware
that any such event has occurred or that such demand has been made or that any
such action has been taken, give notice to all holders of the Notes, specifying
the nature of such event or of such demand or action, as the case may be;
provided, however, that if such event, in the good faith judgment of the
Corporation, will be cured within ten days after the Corporation has knowledge
that such event would, with or without notice or lapse of time or both,
constitute such an Event of Default, no such notice need be given if such Event
of Default shall be cured within such ten day period.

      (d) Merger or Consolidation. If the Corporation shall effect a merger or
consolidation in which it is not the surviving entity, then the Corporation
shall take such action as may be necessary, as a condition to consummating such
transaction, to cause the surviving entity to assume all of the Corporation's
obligations under this Note, as if such entity had

                                       10
<PAGE>

been the original issuer thereof, and such entity shall acknowledge in writing
its obligation to fully and timely honor the Corporation's obligations under
this Note.

            7. Modification; Waiver. The Corporation may, with the written
consent of the holders of not less than 66 2/3% in principal amount of the Notes
then outstanding, modify the terms and provisions of the Notes or the rights of
the holders of the Notes or the obligations of the Corporation thereunder, and
the observance by the Corporation of any term or provision of the Notes may be
waived with the written consent of the holders of not less than 66 2/3% in
principal amount of the Notes then outstanding, provided, however, that no such
modification or waiver shall:

      (a) change the maturity of any Note or reduce the principal amount thereof
or reduce the rate or extend the time of payment of interest thereon or reduce
the amount or change the time of payment of premium payable on any prepayment
thereof without the consent of the holder of each Note so affected; or

      (b) give any Note any preference over any other Note; or

      (c) reduce the aforesaid percentage of Notes, the consent of the holders
of which is required for any such modification.

            Any such modification or waiver shall apply equally to all the
holders of the Notes and shall be binding upon them, upon each future holder of
any Note and upon the Corporation, whether or not such Note shall have been
marked to indicate such modification or waiver, but any Note issued thereafter
shall bear a notation referring to any such modification or waiver. Promptly
after obtaining the written consent of the holders as herein provided, the
Corporation shall transmit a copy of such modification or waiver to all the
holders of the Notes at the time outstanding.

            8. Events of Default. If any one or more of the following events
(herein called "Events of Default"), shall occur, for any reason whatsoever, and
whether such occurrence shall, on the part of the Corporation or any subsidiary,
be voluntary or involuntary or come about or be effected by operation of law or
pursuant to or in compliance with any judgment, decree or order of a court of
competent jurisdiction or any order, rule or regulation of any administrative or

                                       11
<PAGE>

other governmental authority, and such Event of Default shall be continuing:

                  (a) default shall be made in the payment of the principal when
and as the same shall become due and payable, whether on demand or at a date
fixed for prepayment or by acceleration or otherwise; or

                  (b) default shall be made in the payment of any installment of
interest when and as the same shall become due and payable or at a date fixed
for prepayment or by acceleration or otherwise and such default shall continue
for a period of 5 days; or

                  (c) default shall be made in the due observance or performance
of any other covenant, condition or agreement on the part of the Corporation to
be observed or performed pursuant to the terms hereof and such default shall

having jurisdiction in the premises in respect of the Corporation or any

liquidator, assignee, custodian, trustee, sequestrator (or similar official) of
the Corporation or any subsidiary or for any substantial part of any of their
property, or ordering the winding-up or liquidation of any of their affairs and

due and payable together with interest accrued thereon without presentment,
demand, protest or further notice of any kind, all of which are expressly waived
to the extent permitted by law; provided, however, that, upon the occurrence and
during the continuance of any of the events specified in paragraph (a) or (b) of
this Section 8, the holder of any Note at the time outstanding may, at its
option by notice in writing to the Corporation, declare any Note or Notes then
held by it to be, and such Note or Notes shall thereupon be and become,
forthwith due and payable together with interest accrued thereon without
presentment, demand, protest or further notice of any kind, all of which are
expressly waived to the extent permitted by law.

            At any time after any declaration of acceleration has been made as
provided in this Section 8, the holders of at least 66 2/3% in principal amount
of the Notes then outstanding may, by notice to the Corporation, rescind such
declaration and its consequences, provided, however, that no such rescission
shall extend to or affect any subsequent default or Event of Default or impair
any right consequent thereon.

            Without limiting the foregoing, the Corporation hereby waives any
right to trial by jury in any legal proceeding related in any way to this Note
or the Notes and agrees that any such proceeding may, if the holder so elects,
be brought and enforced in the courts in the State of Texas and the Corporation
hereby waives any objection to jurisdiction or venue in any such proceeding
commenced in such courts. The Corporation further agrees that any process
required to be served on it for purposes of any such proceeding may be served on
it, with the same effect as personal service by registered mail addressed to it
at its office or agency set forth in paragraph (a) of Section 6 for purposes of
notices hereunder.

            9. Suits for Enforcement. Subject to the provisions of Section 12 of
this Note, in case any one or more of the Events of Default specified in Section
8 of this Note shall occur and be continuing, the holder of this Note may
proceed to protect and enforce its rights by suit in equity, action at law
and/or by other appropriate proceeding, whether for the specific performance of
any covenant or agreement contained in this Note or in aid of the exercise of
any power granted in this Note, or may proceed to enforce the payment of this
Note or to enforce any other ~1egal or equitable right of the holder of this
Note.

            In case of any default under this Note, the Corporation will pay to
the holder thereof such amounts as shall be sufficient to cover the reasonable
costs and expenses of such holder due to said default, including without
limitation collection

                                       13
<PAGE>

costs and reasonable attorneys' fees, to the extent actually incurred.

            10. Remedies Cumulative. No remedy herein conferred upon the holder
of this Note is intended to be exclusive of any other remedy and each and every
such remedy shall be cumulative and shall be in addition to every other remedy
given hereunder or now or hereafter existing at law or in equity or by statute
or otherwise.

            11. Remedies Not Waived. No course of dealing between the
Corporation and the holder of this Note or any delay on the part of the holder
hereof in exercising any rights hereunder shall operate as a waiver of any right
of any holder of this Note.

            12. Subordination. (a) Anything contained in this Note to the
contrary notwithstanding, the indebtedness evidenced by this Note shall be
subordinate and junior, to the extent set forth in the following paragraphs (A),
(B), (C) and (D), to all Senior Indebtedness of the Corporation. "Senior
Indebtedness" shall mean the principal of, premium, if any, and interest
~including any interest accruing subsequent to the filing of a petition of
bankruptcy at the rate provided for in the documentation with respect thereto,
whether or not such interest is an allowed claim under applicable law and
including any loans made to the Corporation as a debtor in possession in any
bankruptcy proceeding by any persons who were the holders of any Senior
Indebtedness on the date such bankruptcy proceeding was commenced) on all
indebtedness to a bank or banks for borrowed money now existing or hereinafter
incurred which by its terms is not subordinated to any other indebtedness of the
Corporation.

            (A) In the event of any insolvency, bankruptcy, liquidation,
reorganization or other similar proceedings, or any receivership proceedings in
connection therewith, relative to the Corporation or its creditors or its
property, and in the event of any proceedings for voluntary liquidation,
dissolution or other winding up of the Corporation, whether or not involving
insolvency or bankruptcy proceedings, then all Senior Indebtedness shall first
be paid in full before any payment, whether on account of principal, interest or
otherwise, is made upon the Notes.

            (B) In any of the proceedings referred to in paragraph (A) above,
any payment or distribution of any kind or character, whether in cash, property,
stock or obligations which may be payable or deliverable in respect of the Notes
shall be paid or delivered directly to the holders of Senior Indebtedness for

                                       14
<PAGE>

application in payment thereof, unless and until all Senior Indebtedness shall
have been paid in full.

            (C) No payment shall be made, directly or indirectly, on account of
the Notes (i) upon maturity of any Senior Indebtedness obligation, by lapse of
time, acceleration (unless waived) , or otherwise, unless and until all
principal thereof and interest thereon and all other obligations in respect
thereof shall first be paid in full and have terminated, or (ii) upon the
happening of any default in payment of any principal of, premium, if any, or
interest on or any other amounts payable in respect of Senior Indebtedness when
the same becomes due and payable whether at maturity or at a date fixed for
prepayment or by declaration or otherwise (a "Senior Payment Default"), unless
and until such Senior Payment Default shall have been cured or waived or shall
have ceased to exist.

            (D) Upon the happening of an event of default (other than as
described in clause (A), (B) or (C) above) with respect to any Senior
Indebtedness permitting (after notice or lapse of time or both) one or more
holders of such Senior Indebtedness to declare such Senior Indebtedness due and
payable prior to the date on which it is otherwise due and payable (a
"Nonmonetary Default"), upon the occurrence of (i) receipt by the holder of this
Note of written notice from a holder of said Senior Indebtedness of a
Nonmonetary Default (any such notice, a "Blockage Notice") , or (ii) if such
Nonmonetary Default results from the acceleration of this Note, the date of such
acceleration; then (x) the Corporation will not make, directly or indirectly, to
the holder of this Note any payment of any kind of or on account of this Note,
(y) the holder of this Note will not accept from the Corporation any payment of
any kind of or on account of this Note and (z) the holder of this Note may not
take, demand, receive, sue for, accelerate or commence any remedial proceedings
with respect to any amount payable under this Note, unless and until in each
case described in clauses (x), (y) and (z) all such Senior Indebtedness shall
have been paid in full; provided, however, that if such Nonmonetary Default
shall have occurred and be continuing for a period (a "Blockage Period")
commencing on the earlier of the date of receipt of such Blockage Notice or the
date of the acceleration of this Note and ending 179 days thereafter (it being
understood that not more than one Blockage Period may be commenced with respect
to this Note during any period of 360 consecutive days), and during such
Blockage Period (i) such Nonmonetary Default shall not have been cured or
waived, (ii) the holder of such Senior Indebtedness shall not have made a demand
for payment and commenced an action, suit or other proceeding against the
Corporation and (iii) none of the events described in subsection (A) above shall
have occurred, then (to the extent not otherwise prohibited by subsections (A),
(B) or (C) above) the Corporation may, not less than 10 days after receipt by
the holders of such Senior Indebtedness of written

                                       15
<PAGE>

notice to such effect from the holder of this Note, make and the holder of this
Note may accept from the Corporation all past due and current payments of any
kind of or on account of this Note, and such holder may demand, receive, retain,
sue for or otherwise seek enforcement or collection of all amounts payable on
account of principal of or interest on this Note.

                  (b) Subject to the payment in full of all Senior Indebtedness
as aforesaid, the holder of this Note shall be subrogated to the rights of the
holders of Senior Indebtedness to receive payments or distributions of any kind
or character, whether in cash, property, stock or obligations, which may be
payable or deliverable to the holders of Senior Indebtedness, until the
principal of, and interest on, this Note shall be paid in full in cash, and, as
between the Corporation, its creditors other than the holders of Senior
Indebtedness, and the holders of this Note, no such payment or distribution made
to the holders of Senior Indebtedness by virtue of this Section 12 which
otherwise would have been made to the holder of this Note shall be deemed a
payment by the Corporation on account of the Senior Indebtedness, it being
understood that the provisions of this Section 12 are and are intended solely
for the purposes of defining the relative rights of the holder of this Note, on
the one hand, and the holders of the Senior Indebtedness, on the other hand,
Subject to the rights, if any, under this Section 12 of holders of Senior
Indebtedness to receive cash, property, stock or obligations otherwise payable
or deliverable to the holder of this Note, nothing herein shall either impair,
as between the Corporation and the holder of this Note, the obligation of the
Corporation, which is unconditional and absolute, to pay to the holder of this
Note the principal hereof and interest hereon in accordance with its terms or
prevent (except as otherwise specified herein) the holder of this Note from
exercising all remedies otherwise permitted by applicable law or hereunder upon
default hereunder.

                  (c) If any payment or distribution of any character or any
security, whether in cash, securities or other property, shall be received by
any holder of this Note in contravention of any of the terms hereof or before
all the Senior Indebtedness obligations have been paid in full, such payment or
distribution or security shall be received in trust for the benefit of, and
shall be paid over or delivered and transferred to, the holders of the Senior
Indebtedness at the time outstanding in accordance with the priorities then
existing among such holders for application to the payment of all Senior
Indebtedness remaining unpaid, to the extent necessary to pay all such Senior
Indebtedness in full in cash, In the event of the failure of any such holder to
endorse or assign any such payment, distribution or security, each holder of any
Senior Indebtedness is hereby irrevocably authorized to endorse or assign the
name.

good condition and repair. Tenant shall repair or replace, subject to Landlord's
direction and supervision, any damage to the Building caused by Tenant or
Tenant's agents, employees, contractors, or invitees. If Tenant fails to make
such repairs or replacements within fifteen (15) days after the occurrence of
such damage, or longer period if reasonably necessary to complete the repair or
replacement, then Landlord may make such repairs or replacements at Tenant's
cost, in which event the sums paid by Landlord shall be reimbursed by Tenant
within ten (10) days after Landlord has delivered to Tenant an invoice therefor.
Tenant shall surrender to Landlord immediate possession of the Premises and all
keys thereto at the expiration of this Lease, in as good condition as when
received, ordinary wear and tear excepted.

      9. Taxes. Landlord shall pay the real estate taxes on the Property during
the Lease Term.

      (i) Tenant shall pay Landlord, as Additional Rent, Tenant's Share of the
ad valorem taxes on the Property for any year during the Lease Term. Tenant
shall be responsible for the pro rata portion of such Additional Rent for any
fractional part of a calendar year at the beginning, or preceding the end, of
the Lease Term. If the termination of this Lease occurs before the tax rate is
fixed for the particular year, the proration shall be upon the basis of the tax
rate for the preceding year applied to the latest assessed valuation, and,
notwithstanding the termination of this Lease, any difference in the actual real
estate taxes for such year shall be adjusted between the parties upon receipt of
written evidence of the payment thereof.

      (ii) In the event the real estate taxes levied against the Property for
any calendar year during the Lease Term are increased as a result of any
alterations, additions or improvements made by Tenant or by Landlord at the
request of Tenant, Tenant shall pay to Landlord the amount of such increase
within fifteen (15) days after Landlord's billing therefor. Landlord shall
obtain from the tax assessor or assessors a written statement of the total
amount of such increase.

      (iii) Tenant shall pay all taxes charged against trade fixtures,
furnishings, equipment or any other personal property belonging to Tenant.
Tenant shall try to have its personal property taxed separately from the

after Tenant receives a written statement for such personal property taxes.

      10. Compliance With Laws. Tenant shall comply with all laws, ordinances,
orders, rules and regulations of all governmental bodies (federal, state,
municipal and other agencies or bodies having any jurisdiction) pertaining to
the use, condition, or occupancy of the Premises. Tenant will not occupy or use,
or permit any portion of the Premises to be occupied or used, for any business
or purpose which is illegal or disreputable in any manner, or extra hazardous on
account of fire, or permit anything to be done which will in any way increase
the rate of fire insurance on the Building or its contents, and in the event
that there shall be any increase in the rate of the insurance on the Building or
its contents created by Tenant's acts or the conduct of its business therein,
Tenant agrees to pay such increase.

      11. Alterations and Improvements. Tenant shall make no alterations,
changes or improvements to the Premises without the prior written consent of
Landlord, not to be unreasonably withheld or delayed, and without first
submitting to Landlord plans and specifications for such work. All work done by
Tenant shall be performed in a good and workmanlike manner, in compliance with
all applicable laws and at such times and in such manner as not to cause
interference with any work of Landlord or with other tenants in the Building.
Any alterations, additions, or improvements (whether temporary or permanent in
character) made in or upon the Premises, either by Landlord or Tenant (including
but not be limited to, wall covering, carpeting or other floor covering,
paneling, built-in trac moveable file systems, nurses call systems, built-in
book shelves and built-in cabinet work), shall be deemed a part of the property
of Landlord and shall be surrendered with the Premises at termination of this
Lease and shall remain on the Premises without compensation to Tenant. All other
furniture, movable trade fixtures (including but not be limited to, x-ray
equipment, audio booths and laboratory equipment) and equipment installed by
Tenant may (and shall at Landlord's option) be removed by Tenant at the
termination of this Lease. Landlord reserves the right to prescribe that all
improvements by Tenant shall be the same as or shall conform with Building
standard items, materials and types of construction. All alterations, physical
additions or improvements must be constructed by a contractor and workmen
approved by Landlord, which approval shall not be unreasonably withheld or
delayed. All furniture, movable trade and equipment installed by Tenant not
removed from the Premises within fifteen (15) days of the termination of the
Lease shall be conclusively presumed to have been abandoned by Tenant and
Landlord may, at its option, take over the possession of such property and
either (a) declare same to be property of Landlord by written notice thereof to
Tenant or (b) at the sole risk, cost, and expense of Tenant, remove the same or
any part thereof in any manner that Landlord shall choose and dispose of or
store the same without incurring liability to Tenant or to any other person.

      *

      13. Assignment and Subletting. Tenant shall not sublet the Premises in
whole or in part, nor assign or transfer this Lease or any interest herein in
any manner whatsoever, directly or indirectly, voluntarily or by operation of
law without Landlord's prior written consent, which consent shall not be
unreasonably withheld or delayed.

      14. Indemnification. Landlord shall not be liable to Tenant or to Tenant's
employees, agents, subtenants, guests or invitees, or to any other person
whomsoever, for any injury to persons or damage to the property on or about the
Premises or any other part of the Building or Land from any cause, including,
any injury or damages caused by or arising out of the negligence or misconduct
of any person entering upon the Land, the Premises or the Building. Tenant shall
indemnify and hold Landlord harmless from and against any and all claims,
demands, losses, fines, assessments, penalties, damages to persons (including
damages for personal injury and death), damages to property, causes of action
and costs (including, without limitation, costs of reasonable attorneys' fees)
caused by or arising out of (i) the negligence or misconduct of Tenant or its
employees, agents, subtenants, guests or invitees, or any other person entering
the Premises or Building under the express or implied invitation of Tenant; (ii)
the use or occupancy of the Premises by Tenant and the conduct of its business
therein; or (iii) any breach or default by Tenant in the performance of its
obligations hereunder. Tenant's obligations hereunder shall survive the
termination of this Lease. Tenant shall have no obligation to indemnify Landlord
for Landlord's negligence, willful misconduct or breach of this Lease.

                                      -4-

      15. Insurance. Tenant shall at all times during the term of this Lease, at
its own expense, keep in full force and effect (a) all risk insurance insuring
all property of Tenant located in the Premises at its full replacement value,
(b) commercial general liability insurance covering personal injury, including
death, and contractual liability, and broad form property damage with combined
single limits of not less than $1,000,000 to one or more than one person as the
result of any one accident or occurrence, and (C) workmen's compensation and
employer's liability insurance in form and amount as required by law. Landlord
shall be named an additional insured on all such policies. The policies or duly
executed certificates for the same, together with satisfactory evidence of the
payment of the premiums therefor, shall be delivered to Landlord prior to
Tenant's occupancy of the Premises and upon renewals of such policies not less
than fifteen (15) days prior to the expiration of the term of such coverage. All
such policies and certificates shall be in form and issued by companies
reasonably satisfactory to Landlord.

      (i) During the Lease Term, Landlord shall maintain policies of insurance
covering loss of or damage to the Property in such amount or percentage of
replacement value as Landlord may determine, in its sole discretion. Such
policies shall provide protection against all perils included within
classification of fire and extended coverage and any other perils which Landlord
deems necessary. Landlord may obtain insurance coverage for building
improvements installed by Tenant in or on the Leased Space. Tenant shall, at
Tenant's expense, maintain such primary or additional insurance on its fixtures,
equipment and building improvements as Tenant deems necessary to protect its
interest and its obligations hereunder. Tenant shall not do or permit to be done
anything which invalidates any such insurance policies. Any casualty insurance
which may be carried by Landlord or Tenant shall be for the sole benefit of the
party carrying such insurance and under its sole control.

      (ii) Tenant shall not permit any operation or activity to be conducted or
storage or use of any volatile or any other materials on the Property that would
cause suspension or cancellation of any fire and extended coverage insurance
policy carried by Landlord, or increase the premiums therefor, without the prior
written consent of Landlord. If Tenant's use and occupancy of the Leased Space
causes an increase in the premiums for any fire and extended coverage insurance
policy carried by Landlord on the day before Tenant shall have first gone into
possession of the Leased Space under this Lease, Tenant shall pay the amount of
such increase to Landlord within fifteen (15) days after billing and
presentation of written evidence of the increase by Landlord.

      (iii) Tenant shall pay Landlord, as Additional Rent, Tenant's Share of the
excess, if any, of the costs of insurance maintained by Landlord pursuant to
Section 14(i) for any calendar year during the Lease Term over the costs for
such insurance for the calendar year in which the Commencement Date occurs; if
the Commencement Date is not the first day of a calendar year, the insurance
costs for the first calendar year of the Lease Term shall be annualized. Such
Additional Rent shall be due and payable as provided in Section 6.

      16. Mutual Waivers of Recovery. Landlord, Tenant and all parties claiming
under them each mutually release and discharge each other from all claims and
liabilities arising from or caused by fire or other casualty or hazard which is
covered or could be covered by fire and extended coverage or all-risk property
insurance in respect of the Building, the Premises and the personal property
situated therein, or in connection with activities conducted in the Premises or
in the Building, no matter how caused, including negligence, and each waives any
right of recovery which might otherwise exist on account thereof; provided, the
provisions of this paragraph shall not prevent any action by Landlord against
Tenant or by Tenant against Landlord for the amount of any deductible.

      17. Hazardous Materials. Tenant shall not permit within the Premises, or
cause within the Building or Land, the storage, use, discharge, escape, disposal
or release of any biologically

                                      -5-
<PAGE>

or chemically active or other hazardous substances or materials (collectively
"Hazardous Substances") in any manner not permitted by law or by the highest
standards prevailing in the industry for the storage and use of Hazardous
Substances, nor allow to be brought into the Premises any such Hazardous
Substances except for use in the ordinary course of Tenant's business, and then
only after written notice is given to Landlord of the identity of such Hazardous
Substances. Without limitation, Hazardous Substances shall include those
substances defined as "hazardous substances," "hazardous materials," "hazardous
wastes," "toxic substances," or other similar classifications described in the
Comprehensive Environmental Response Compensation and Liability Act of 1960, as
amended, 42 U.S.C. ss. 9601 et seq., the Resource Conservation and Recovery Act,
as amended, 42 U.S.C. ss. 6901 et seq., and any other applicable federal, state
or local laws and regulations. Tenant shall indemnify and hold Landlord harmless
from any and all claims, demands, losses, fines, assessments, penalties and
damages arising from any discharge or release of any Hazardous Substances on or
about the Premises during the period Tenant is in possession of the Premises or
arising out of Tenant's use or occupancy of the Premises or breach of the terms
of this paragraph. The covenants contained in this paragraph shall survive the
expiration or earlier termination of the Lease.

      18. Rules and Regulations. Tenant covenants and agrees that Tenant will
comply fully with all of the rules and regulations of the Building, a copy of
which are attached hereto as Exhibit "D" and made a part hereof for all
purposes. Landlord shall at all times have the right to change or amend such
rules and regulations or to make such other rules and regulations as may be
deemed advisable by Landlord for the safety, care and cleanliness of the
Building and for preservation of good order therein, all of which changes and
amendments will be sent by Landlord to Tenant in writing and thereafter carried
out and observed by Tenant. Tenant shall be responsible for the compliance with
the rules and regulations by Tenant's agents, employees, guests, visitors and
invitees.

      19. Acceptance of Premises. Tenant accepts the Premises as suitable for
the purposes for which same are leased, and accepts the Building and each and
every appurtenance thereof and waives visible defects therein.

      20. Entry and Inspection. Tenant will permit Landlord and its agents and
representatives to enter the Premises, at all reasonable hours and with 24 hours
prior notice (or at any time in the event of an emergency), to inspect the
Premises or to clean or make repairs, alterations, or additions as Landlord may
deem necessary or desirable to the Premises or to other portions of the Building
or to show the Premises to prospective purchasers, tenants or lenders. Tenant
shall not be entitled to any abatement or reduction of rent by reason of such
entry.

      21. Tenant's Risk. All personal property of Tenant, its employees and
invitees shall remain in the Premises at the sole risk of the owners thereof,
and Landlord shall not be liable for burglary, theft, damage or loss thereto.
Landlord shall not be liable for any losses to Tenant, its employees and
invitees due to fire, windstorm, hail, water, explosion, aircraft or other means
of locomotion, leaking gas, other physical causes. Tenant shall maintain all
equipment and appliances installed by Tenant in the Premises so that the same
will not cause damage to the Building or other tenants therein.

      22. Damage or Destruction. If the Premises or other improvements situated
on the Property should be in part or in whole damaged or destroyed by fire,
tornado or other casualty, Tenant shall immediately give written notice thereof
to Landlord. If the Premises or other improvements situated on the Property
should be damaged by fire, tornado or other casualty but to such an extent that
rebuilding or repairs can reasonably be completed within one hundred eighty
(180) days from the date Tenant delivers written notification to Landlord of the
happening of the damage, this Lease shall not terminate, but Landlord shall, at
its sole cost and expense, proceed

                                      -6-
<PAGE>

forthwith and use reasonable diligence to rebuild or repair such Premises and
other improvements on the Property to substantially the condition in which they
existed prior to such damage; provided, however, if the casualty occurs during
the final six (6) months of the Lease Term, Landlord shall not be required to
rebuild or repair such damage unless Tenant shall exercise its renewal option
within fifteen (15) days after the date of receipt by Tenant of the notification
of the occurrence of the damage. If Tenant does not elect to exercise its
renewal option or if there is no renewal option contained herein or previously
unexercised at such time, this Lease shall terminate at the option of Landlord
and rent shall be abated for the unexpired portion of the Lease, effective from
the date of actual receipt by Landlord of the written notification of the
damage. If the Premises and other improvements are to be rebuilt or repaired and
are untenable in whole or in part following such damage, the rent payable
hereunder during the period in which they are untenable shall be abated with
respect to that portion of the Premises rendered untenable during such period.
If the Premises or other improvements situated on the Property should be
substantially or totally destroyed by fire, tornado or other casualty, or so
damaged that rebuilding or repairs cannot reasonably be completed within one
hundred eighty (180) days from the date Tenant delivers written notification to
Landlord of the happening of the damage, this Lease shall terminate at the
option either of the Landlord or Tenant and rent shall be abated for the
unexpired portion of this Lease, effective from the date of receipt by Landlord
of such written notification. If this Lease is not terminated, the Premises and
the improvements shall be rebuilt or repaired and rent abated to the extent
provided above.

      23. Condemnation. If, during the term of this Lease or any renewal
thereof, all or a substantial part of the Premises should be taken for any
public or quasi-public use under any governmental law, ordinance or regulation
or by right of eminent domain, or should be sold to the condemning authority
under threat of condemnation, this Lease shall terminate and the rent shall be
abated during the unexpired portion of this Lease, effective from the date of
taking of the Premises by the condemning authority. If less than a substantial
part of the Premises is taken for public or quasi-public use under any
governmental law, ordinance or regulation, or by right of eminent domain, or is
sold to the condemning authority under threat of condemnation, Landlord, at its
option, may by written notice terminate this Lease or shall forthwith at its
sole expense restore and reconstruct the Premises and improvements therein, and
in the event Landlord fails to complete the restoration and construction within
one hundred eighty (180) days of its notice to Tenant advising of its intention
to restore and reconstruct the Premises, Tenant shall have the right to
terminate this Lease. The rent payable hereunder during the unexpired portion of
this Lease shall be adjusted proportionately taking into account such portion of
the Premises taken by the condemning authority. If any condemnation occurs,
Landlord shall receive the entire award or other compensation for the Land, and
all or any portion of the Building, and other improvements taken, and Tenant may
separately pursue a claim against the condemnor for the value of Tenant's
personal property which Tenant is entitled to remove under the Lease, moving
costs, loss of business, and other claims it may have.

                  written notice from Landlord to Tenant of the occurrence of

                  such 30-day period and Tenant commences to cure such failure
                  within such 30-day period and thereafter diligently pursues
                  such cure to completion, then such failure shall not be a
                  default or an event of default unless it is not fully cured
                  within an additional sixty (60) days following the expiration

                  or arrearages in rent, enter upon and take possession of the
                  Premises and expel or remove Tenant and any other person who
                  may be occupying said Premises, or any part thereof, without
                  being liable for prosecution or any claim of damages therefor
                  and Tenant hereby agrees to pay to Landlord on demand the
                  amount of all loss and damage which Landlord may suffer by
                  reason of such termination, whether through inability to relet
                  the Premises on satisfactory terms or otherwise, specifically
                  including but not

                                      -8-
<PAGE>

                  limited to (1) all reasonable expenses necessary to relet the
                  Premises which shall include the cost of renovating,
                  repairing, and altering the Premises for a new tenant or
                  tenants, and all leasing costs associated therewith; and (2)
                  any increase in insurance premiums caused by the vacancy of
                  the Premises.

            (ii)  Enter upon and take possession of the Premises and expel or
                  remove Tenant or any other person who may be occupying said
                  Premises, or any part thereof, without terminating this Lease.
                  Landlord may (but shall be under no obligation to) relet the
                  Premises or any part thereof for the account of Tenant, in the
                  name of Tenant or Landlord or otherwise, without notice to
                  Tenant for such term or terms and on such conditions and for
                  such uses as Landlord in its absolute discretion may determine
                  and Landlord may collect and receive any rents payable by
                  reason of such reletting; and Tenant agrees to pay Landlord on
                  demand ail reasonable expenses necessary to relet the Premises
                  which shall include the cost of renovating, repairing, and

                  liable for any failure to relet the Premises or any part
                  thereof or for any failure to collect any rent due upon any
                  such reletting. No such re-entry or taking of possession of
                  the Premises by Landlord shall be construed as an election on
                  Landlord's part to terminate this Lease unless a written
                  notice of such termination is given to Tenant pursuant to
                  subparagraph (b)(1) above.

            (iii) No repossession or re-entering on the Premises or any part
                  thereof pursuant to subparagraphs (b)(i) and (ii) above or
                  otherwise and no reletting of the Premises or any part thereof
                  pursuant to subparagraph (b)(ii) shall relieve Tenant of its
                  liabilities and obligations hereunder, all of which shall
                  survive such repossession or re-entering, except if the
                  Premises are re-let, Tenant shall only be responsible for the
                  difference in rent if the Premises are re-let at a lower
                  rental rate, and Tenant shall have no indemnity obligations
                  related to the use of the Premises by the new tenant.

            (iv)  In the event Landlord elects to re-enter or take possession of
                  the Premises after Tenant's default, with or without
                  terminating this Lease, Landlord may change locks or alter
                  security devices and lock out, expel or remove Tenant and any
                  other person who may be occupying all or any part of the
                  Premises without being liable for any claim for damages.

            (v)   Nothing contained in this Lease shall be construed as imposing
                  any enforceable duty upon Landlord to relet the Premises and
                  Landlord shall have no duty to mitigate or minimize Landlord's
                  damages by virtue of Tenant's default.

            (vi)  No right or remedy herein conferred upon Landlord is intended
                  to be exclusive of any other right or remedy, and each and
                  every right and remedy shall be cumulative and in addition to
                  any other right or remedy given hereunder or now or hereafter
                  existing at law or in equity or by statute.

      27 Transfer of Landlord's Interest. Landlord may transfer, in whole or in
part, the Building and any of its rights under this Lease. If Landlord transfers
or assigns its rights under this Lease, then Landlord shall be released from any
further obligations arising from and after the date of such transfer.

      28. Waiver. The failure of Landlord to insist at any time upon the strict
performance of any covenant or agreement or to exercise any right, power, or
remedy contained in this Lease shall not be construed as a waiver or a
relinquishment thereof for the future. The waiver of any violation of any term,
covenant, agreement, or condition contained in this Lease shall not prevent a
subsequent act, which would have originally constituted a violation from having
all the force and effect of an original violation. A receipt by Landlord of any
rent with knowledge of the breach of any covenant or agreement contained in this
Lease shall not be deemed a waiver of such breach, and no waiver by Landlord of
any provision of this Lease shall be deemed to have been made unless expressed
in writing and signed by Landlord.

      29. Subordination of Lease. This Lease shall be subordinate to any and all
deeds of trust and ground leases now or hereafter encumbering the Building, and
all refinancings, renewals, modifications, extensions or consolidations thereof.
Tenant agrees to attorn to any mortgagee or trustee under a deed of trust or
purchaser at a foreclosure sale or trustee's sale as Landlord under this Lease
provided such mortgagee, trustee or purchaser delivers to Tenant a
nondisturbance agreement whereby it agrees to honor the Lease (including all
renewal options) so long as Tenant is not in default under the Lease. Tenant
covenants and agrees that Tenant shall, within five (b) days after Landlord's
request, execute and deliver to Landlord whatever instruments may be reasonably
required to acknowledge and further evidence the subordination of this Lease
and/or the attornment by Tenant to such mortgagee, trustee or purchaser, if the
nondisturbance agreement described above is provided. Any holder of a deed of
trust covering all or any part of the Building may at any time elect to have
this Lease have priority over its deed of trust by executing an instrument of
subordination or placing a clause of such subordination in any pleadings or in
its deed of trust and recording the same.

      30. Possession. Landlord shall use reasonable diligence to complete the
Premises by the Commencement Date; however, if for any reason the Premises shall
not be ready for occupancy by Tenant at such time, this Lease shall not be
affected thereby except that the Commencement Date of this Lease shall be
deferred to and begin upon the date that the Premises shall be ready for
occupancy and this Lease shall run for the full term thereafter, and Tenant
shall have no claim against Landlord by reason thereof.

date of this Lease or applicable option term. If such option is exercised,
Tenant shall have the right to renew this Lease for a second three-year renewal
term, by delivering Landlord written notice not later than ninety (90) days
prior to the expiration of the first renewal term. Any renewal of this Lease
shall be on the terms and conditions set forth in this Lease and at a monthly
rental equal to the prevailing rate then being charged by Landlord for
comparable space in the Building to tenants that are not affiliated with
Landlord, taking into account the quality, size, utility and location of the
Premises, and subject to increase or adjustment as provided in Section 6 above,

      34. Sales Tax. In the event that any sales, use or revenue tax is levied
or imposed by any governmental authority upon the rent paid by Tenant herein or
for the use or occupancy of the Premises try Tenant, then Tenant agrees to pay
such tax monthly to the Landlord, as an additional consideration and rent for
the use and occupancy of the Premises, unless such tax results from the actions
of Landlord.

      35. Independence and Purpose of Relationship. Tenant and Landlord each
represent and warrant to the other that the transactions contemplated by this
Lease are lease transactions only and that the only relationship between the
parties hereto is that of landlord and tenant. Notwithstanding the foregoing,
Tenant and Landlord recognize that the Tenant may have patients who require
services offered by the Landlord or its affiliates. Landlord and Tenant hereby
represent and warrant that nothing in this Lease is intended to require or
involve in any manner whatsoever the referral of patients to the Landlord or its
affiliates and no payments made under any terms or conditions of this Lease are
in exchange for or conditioned upon any referral of patients. Any referral of
patients for medical services by Landlord or its affiliates or Tenant shall be
based solely on the medical needs and wishes of such patients, and nothing in
this Lease prohibits Tenant or Landlord from referring patients to other
healthcare providers or physicians. It is expressly the intent of Landlord and
Tenant to comply with all federal and state laws limiting, prohibiting, or
otherwise pertaining to referrals or remuneration for the furnishing of health
services, including, but not limited to, 42 U.S.C. ss. 1320a-7(b), et seq., 42

(18%) per annum or the highest lawful rate of interest permitted by Texas or
federal law, whichever rate of interest is lower.

      (l) Personal Liability. The liability of Landlord to Tenant for any
default by Landlord under the terms of this Lease shall be limited to the

remedies which Tenant may have in the event of default by Landlord hereunder

however, if the casualty occurs during the final six (6) months of the Lease
Term, Landlord shall not be required to rebuild or repair such damage unless
Tenant shall exercise its renewal option within fifteen (15) days after the date
of receipt by Tenant of the notification of the occurrence of the damage. If
Tenant does not elect to exercise its renewal option or if there is no renewal
option contained herein or previously unexercised at such time, this Lease shall
terminate at the option of Landlord and rent shall be abated for the unexpired
portion of the Lease, effective from the date of actual receipt by Landlord of
the written notification of the damage. If the Premises and other improvements
are to be rebuilt or repaired and are untenable in whole or in part following
such damage, the rent payable hereunder during the period in which they are
untenable shall be abated with respect to that portion of the Premises rendered
untenable during such period. If the Premises or other improvements situated on
the Property should be substantially or totally destroyed by fire, tornado or
other casualty, or so damaged that rebuilding or repairs cannot reasonably be
completed within one hundred eighty (180) days from the date Tenant delivers
written notification to Landlord of the happening of the damage, this Lease
shall terminate at the option either of the Landlord or Tenant and rent shall be
abated for the unexpired portion of this Lease, effective from the date of
receipt by Landlord of such written notification. If this Lease is not
terminated, the Premises and the improvements shall be rebuilt or repaired and
rent abated to the extent provided above.

      22. Condemnation. If, during the term of this Lease or any renewal
thereof, all or a substantial part of the Premises should be taken for any
public or quasi-public use under any governmental law, ordinance or regulation
or by right of eminent domain, or should be sold to the condemning authority
under threat of condemnation, this Lease shall terminate and the rent shall be
abated during the unexpired portion of this Lease, effective from the date of
taking of the Premises by the condemning authority. If less than a substantial
part of the Premises is taken for public or quasi-public use under any
governmental law, ordinance or regulation, or by right of eminent domain, or is
sold to the condemning authority under threat of condemnation, Landlord, at its
option, may by written notice terminate this Lease or shall forthwith at its
sole expense restore and reconstruct the Premises and improvements therein, and
in the event Landlord fails to complete the restoration and construction within
one hundred eighty (180) days of its notice to Tenant advising of its intention
to restore and reconstruct the Premises, Tenant shall have the right to
terminate this Lease. The rent payable hereunder during the unexpired portion of
this Lease shall be adjusted proportionately taking into account such portion of
the Premises taken by the condemning authority. If any condemnation occurs,
Landlord shall receive the entire award or other compensation for the Land, and
all or any portion of the Building, and other improvements taken, and Tenant may
separately pursue a claim against the condemnor for the value of Tenant's
personal property which Tenant is entitled to remove under the Lease, moving
costs, loss of business, and other claims it may have.

      23. Mechanic's Liens. Tenant shall not permit any mechanic's liens to be
filed against the Premises or the Building for any work performed, materials
furnished, or obligation incurred by or at the request of Tenant. If such a lien
is filed, then Tenant shall, within ten (10) days after Landlord has delivered
notice of the filing to Tenant, either pay the amount of the lien or diligently
contest such lien and deliver to Landlord a bond or other security reasonably
satisfactory' to Landlord. If Tenant fails to timely take either such action,
then Landlord may pay the lien clam without inquiry as to the validity thereof,
and any amounts so paid, including expenses and interest, shall be paid by
Tenant to Landlord within ten (10) days after Landlord has delivered to Tenant
an invoice therefor.

      24. Holding Over. No holding over by Tenant after the term of this Lease,
either with or without consent and acquiescence of Landlord, shall operate to
extend this Lease for a period longer than one month and any holding over with
the consent of Landlord in writing shall constitute a lease from month to month
at a

                                      -6-

monthly rental equal to 125% of the then applicable monthly rent and other sums
provided herein, and subject to all of the other terms, provisions, covenants
and agreements on the part of Tenant hereunder.

defaults or events of default by Tenant under this Lease:

            (i)   Tenant shall fail to pay when due any installment of rent or
                  any other sum of money payable by Tenant to Landlord and such
                  failure shall continue for a period of ten (10) days following
                  written notice thereof from Landlord to Tenant, provided,
                  Landlord shall not be required to deliver to Tenant more than
                  two (2) such notices in any calendar year.

            (ii)  Tenant shall fail to comply with any term, provision, or

                  written notice from Landlord to Tenant of the occurrence of
                  such failure; however, if such failure cannot be cured within
                  such 30-day period and Tenant commences to cure such failure
                  within such 0-day period and thereafter diligently pursues
                  such cure to completion, then such failure shall not be a
                  default or an event of default unless it is not fully cured
                  within an additional sixty (60) days following the expiration
                  of the 30-day period.

            (iii) Any petition shall be filed by or against Tenant under the
                  United States Bankruptcy Code, as amended, or under any

                  thereof, and such petition shall not be dismissed within sixty
                  (60) days of filing, or Tenant shall be adjudged bankrupt or
                  insolvent in any proceedings filed thereunder.

            (iv)  A receiver or trustee shall be appointed for all or

                  the action in which such appointment was ordered dismissed,
                  within sixty (60) days of filing.

            (v)   Tenant shall make a general assignment for the benefit of

      (b) If any default or event of default shall have occurred, Landlord shall
have the right at its election, then or any time thereafter while such default
or event of default shall continue, to pursue any one or more of the following
remedies:

            (i)   Terminate this Lease by giving notice thereof to Tenant, in
                  which event Tenant shall immediately surrender the Premises to
                  Landlord and if Tenant fails to do so, Landlord may without
                  prejudice to any other remedy which it may have for possession
                  or arrearages in rent, enter upon and take possession of the
                  Premises and expel or remove Tenant and any other person who
                  may be occupying said Premises, or any part thereof, without
                  being liable for prosecution or any claim of damages therefor
                  and Tenant hereby agrees to pay to Landlord on demand the
                  amount of all loss and damage which Landlord may suffer by
                  reason of such termination, whether through inability to relet
                  the Premises on satisfactory terms or otherwise, specifically
                  including but not limited to (1) all reasonable expenses
                  necessary to relet the Premises which shall include the cost
                  of renovating, repairing, and altering the Premises for a new
                  tenant or tenants, and all

                                      -7-
<PAGE>

                  leasing costs associated therewith; and (2) any increase in
                  insurance premiums caused by the vacancy of the Premises.

            (ii)  Enter upon and take possession of the Premises and expel or
                  remove Tenant or any other person who may be occupying said
                  Premises, or any part thereof, without terminating this Lease.
                  Landlord may (but shall be under no obligation to) relet the
                  Premises or any part thereof for the account of Tenant, in the
                  name of Tenant or Landlord or otherwise, without notice to
                  Tenant for such term or terms and on such conditions and for
                  such uses as Landlord in its absolute discretion may determine
                  and Landlord may collect and receive any rents payable by
                  reason of such reletting; and Tenant agrees to pay Landlord on
                  demand all reasonable expenses necessary to relet the Premises
                  which shall include the cost of renovating, repairing, and
                  altering the Premises for a new tenant or tenants and all
                  leasing costs associated therewith and Tenant further agrees
                  to pay Landlord on demand any deficiency that may arise by
                  reason of such reletting. Landlord shall not be responsible or
                  liable for any failure to relet the Premises or any part
                  thereof or for any failure to collect any rent due upon any
                  such reletting. No such re-entry or taking of possession of
                  the Premises by Landlord shall be construed as an election on
                  Landlord's part to terminate this Lease unless a written
                  notice of such termination is given to Tenant pursuant to
                  subparagraph (b)(i) above.

            (iii) No repossession or re-entering on the Premises or any part
                  thereof pursuant to subparagraphs (b)(i) and (ii) above or
                  otherwise and no reletting of the Premises or any part thereof
                  pursuant to subparagraph (b)(ii) shall relieve Tenant of its
                  liabilities and obligations hereunder, all of which shall
                  survive such repossession or re-entering, except if the
                  Premises are re-let, Tenant shall only be responsible for the
                  difference in rent if the Premise are re-let at a lower rental
                  rate, and Tenant shall have no indemnity obligations related
                  to the use of the Premises by the new tenant.

            (iv)  In the event Landlord elects to re-enter or take possession of
                  the Premises after Tenant's default, with or without
                  terminating this Lease, Landlord may change locks or alter
                  security devices and lock out, expel or remove Tenant and any
                  other person who may be occupying all or any part of the
                  Premises without being liable for any claim for damages.

            (v)   Nothing contained in this Lease shall be construed as imposing
                  any enforceable duty upon Landlord to relet the Premises and
                  Landlord shall have no duty to mitigate or minimize Landlord's
                  damages by virtue of Tenant's default.

            (vi)  No right or remedy herein conferred upon Landlord is intended
                  to be exclusive of any other right or remedy, and each and
                  every right and remedy shall be cumulative and in addition to
                  any other right or remedy given hereunder or now or hereafter
                  existing at law or in equity or by statute.

      26. Transfer of Landlord's Interest. Landlord may transfer, in whole or in
part, the Building and any of its rights under this Lease. If Landlord transfers

further obligations arising from and after the date of such transfer.

      27. Waiver. The failure of Landlord to insist at any time upon the strict
performance of any covenant or agreement or to exercise any right, power, or
remedy contained in this Lease shall not be construed as a waiver or a
relinquishment thereof for the future. The waiver of any violation of any term,
covenant, agreement, or condition contained in this Lease shall not prevent a
subsequent act, which would have originally constituted a violation from having
all the force and effect of an original violation. A receipt by Landlord of any
rent with knowledge of the breach of any covenant or agreement contained in this
Lease shall not be deemed a waiver of such breach, and no waiver by Landlord of
any provision of this Lease shall be deemed to have been made unless expressed
in writing and signed by Landlord.

deeds of trust and ground leases now or hereafter encumbering the Building, and

purchaser at a foreclosure sale or trustee's sale as Landlord under this Lease,
provided such mortgagee, trustee or purchaser delivers to Tenant a
nondisturbance agreement whereby it agrees to honor the Lease (including all
renewal options) so long as Tenant is not in default under the Lease. Tenant
covenants and agrees that Tenant shall, within five (5) stays after Landlord's
request, execute and deliver to Landlord whatever instruments may be reasonably
required to acknowledge and further evidence the subordination of this Lease
and/or the attornment by Tenant to such mortgagee, trustee or purchaser, if the
nondisturbance agreement describe above is provided. Any holder of a deed of
trust covering all or any part of the Building may at any time elect to have
this Lease have priority over its deed of trust by executing an instrument of
subordination or placing a clause of such subordination in any pleadings or in
its deed of trust and recording the same.

      29. Possession. Landlord shall use reasonable diligence to complete the
Premises by the Commencement Date; however, if for any reason the Premises shall
not be ready for occupancy by Tenant at such time, this Lease shall not be
affected thereby except that the Commencement Date of this Lease shall be
deferred to and begin upon the date that the Premises shall be ready for
occupancy and this Lease shall run for the full term thereafter, and Tenant
shall have no claim against Landlord by reason thereof.

            (Amendment to USP Parent's Registration Rights Agreement)

<PAGE>

                                 AMENDMENT NO. 5

                                       TO

                              AMENDED AND RESTATED
                          REGISTRATION RIGHTS AGREEMENT

      AMENDMENT NO. 5 to the Amended and Restated Registration Rights Agreement,
dated as of June 1, 1999 (the "Amendment"), among United Surgical Partners
International, Inc., a Delaware corporation (the "Company"), and the several
other parties named at the foot hereof, amending the Amended and Restated
Registration Rights Agreement dated as of April 30, 1998 among the Company and
the several signatories thereto (the "Registration Rights Agreement"). All
capitalized terms used and not defined herein shall have the meaning set forth
in the Contribution and Purchase Agreement dated as of May 11, 1999 (the
"Contribution Agreement") among USP North Texas, Inc., Baylor Health Services,
Texas Health Ventures Group LLC and THVG/HealthFirst L.L.C.

      On the date hereof, USP, Baylor, THVGI and THVG2 are consummating the
transactions contemplated by the Contribution Agreement pursuant to which the
Company has agreed to issue to Baylor a Convertible Subordinated Promissory Note
(the "Note") convertible into shares of the Company's Class A Common Stock, $.01
par value ("Class A Common Stock").

      It is a condition to the closing of the transactions contemplated by the
Contribution Agreement that the Company and the parties hereto execute this
Amendment.

      Pursuant to Section 13(d) of the Registration Rights Agreement, the
Registration Rights Agreement is hereby amended as follows:

            1. Baylor is hereby made a party to the Registration Rights
Agreement with the same rights (including the right to receive notices under
Sections 4, 5 and 6 of the Registration Rights Agreement) and obligations as a
holder of "Restricted Stock" (with respect to the shares of Class A Common Stock
into which the Note is convertible) as set forth in the Registration Rights
Agreement. Baylor is hereby deemed to be a holder of "Restricted Stock" with all
the rights and, with respect to the shares of Class A Common Stock into which
the Note is convertible, obligations of such a holder as set forth in the
Registration Rights Agreement. Baylor, or its assignee, shall continue to be
deemed such a holder of Restricted Stock for so long as Baylor, or its assignee
holds the Note. Upon any conversion of the Note, the converted shares held by
Baylor or its assignee, will be "Restricted Stock" and Baylor, or its assignee,
will be a holder of "Restricted Stock" with respect to such converted shares and
will have all the rights and obligations of a holder of "Restricted Stock."

            2. Section 13(d) of the Registration Rights Agreement is hereby
amended and restated in its entirety as follows:

                  "(d) This Agreement constitutes the entire agreement of the
                  parties with respect to the subject matter hereof and may be
                  modified or amended except in writing signed by the Company
                  and the holders of not less than two thirds of the Restricted
                  Stock and Investor

                                       1
<PAGE>

                  Shares then outstanding; provided that no such modification or
                  amendment shall deprive any holder of Restricted Stock
                  (including Baylor or its assignee) or Investor Shares of any
                  material right under this Agreement without such holder's
                  consent. The Company will not grant any registration rights to
                  any other person without the written consent of the holders of
                  at least two-thirds of the Restricted Stock and Investor
                  Shares then outstanding if such rights could reasonably be
                  expected to conflict with, or be an a party with, the rights
                  of holders of Restricted Stock or Investor Shares granted
                  under this Agreement; provided, however, that notwithstanding
                  the foregoing, any amendment solely to grant registration
                  rights to additional holders of the capital stock of the
                  Company may be effected in a writing executed solely by the
                  Company and such additional holders if such registration
                  rights are no more favorable than the registration rights
                  granted to any holder of Investor Shares. Any amendment to
                  this Agreement to grant such registration rights to such
                  additional holders of the capital stock of the Company shall
                  not be deemed to be an amendment that adversely affects the
                  rights of any holder hereunder."

            3. The first paragraph of Section 3 of the Registration Rights
Agreement is hereby amended and restated in its entirety as follows:

                  "3. Notice of Proposed Transfer. Prior to any proposed
                  transfer of any Restricted Stock or Investor Shares, as the
                  case may be, (other than under the circumstances described in
                  Section 4, 5 or 6 hereof), the holder thereof shall give
                  written notice to the Company of its intention to effect such
                  transfer. Each such notice shall describe the manner of the
                  proposed transfer and, if requested by the Company, shall be
                  accompanied by an opinion of counsel reasonably satisfactory
                  to the Company (it being agreed that Nossaman, Guthner, Knox &
                  Elliott, LP" shall be satisfactory) to the effect that the
                  proposed transfer of the Restricted Stock or Investor Shares,
                  as the case may be, may be effected without registration under
                  the Securities Act, whereupon the holder of such Restricted
                  Stock or Investor Shares, as the case may be, shall be
                  entitled to transfer such Restricted Stock or Investor Shares,
                  as the case may be, in accordance with the terms of its
                  notice; provided, however, that no such opinion or other
                  documentation shall be required if such notice shall cover a
                  distribution by Welsh, Carson, Anderson & Stowe VII, L.P.
                  ("WCAS VII") or WCAS Healthcare Partners, L.P. to their
                  respective partners; and further provided, that no such
                  opinion or documentation shall be required if such notice
                  shall cover a transfer by Baylor Health Services ("Baylor") to
                  an entity to which Baylor may transfer its membership interest
                  in Texas Health Ventures Group L.L.C. ("THVG I") under Section
                  4.1(a) of the Second Amended and Restated Regulations of THVG
                  I dated as of June 1,

                                       2
<PAGE>

                  1999, so long as Baylor delivers other evidence, reasonably
                  acceptable to the Company to the effect that the proposed
                  transfer may be effected without registration under the
                  Securities Act. Each certificate for Restricted Stock or
                  Investor Shares as the case may be, transferred as above
                  provided shall bear the legend set forth in Section 2 unless
                  (i) such transfer is in accordance with the provisions of Rule
                  144 (or any other rule permitting public sale without
                  registration under the Securities Act) or (ii) the opinion of
                  counsel referred to above is to the further effect that the
                  transferee and any subsequent transferee (other than an
                  affiliate of the Company) would be entitled to transfer such
                  securities in a public sale without registration under the
                  Securities Act."

            4. Schedule I to the Registration Rights Agreement is hereby amended
by adding the following Baylor notice information under the heading of
"Restricted Stockholders":

is hereby in all respects confirmed.

            6. This Amendment shall be governed by and construed in accordance
with the laws of the State of Delaware.

of which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

      1.3. REPRESENTATIONS AND WARRANTIES OF HDT. HDT hereby represents and
warrants to USPI as follows:

         (a) ENFORCEABILITY. HDT is a company organized under the laws of Spain.
HDT has the requisite corporate power and authority to enter into this Agreement
and to consummate the transactions contemplated hereby. This Agreement has been
duly authorized, executed and delivered by HDT and constitutes a valid and
binding obligation of HDT, enforceable in accordance with its terms, except as
enforceability may be limited by bankruptcy, insolvency or other similar laws or
equitable principles affecting the enforcement of creditors' rights generally.
No consents, including but not limited to governmental consents, are required
for HDT to enter into this Agreement and to perform its obligations hereunder.

         (b) CONFLICTS. The execution, delivery and performance of this
Agreement by HDT will not conflict with, result in any breach of or constitute a
default under any agreement, instrument, order, judgment, decree, law or
governmental regulation to which HDT is subject.

         (c) INVESTMENT REPRESENTATIONS.

             (i) HDT acknowledges and understands that the USPI-B Stock has not
been registered under the United States Securities Act of 1933, as amended, and
the rules and regulations thereunder (the "Securities Act"). HDT will purchase
and hold the USPI-B Stock for investment purposes only and not with a view to
the sale or distribution of any part thereof in violation of the Securities Act.

issued in transfer thereof will bear a legend required under the Securities Act
and any applicable state securities law.

             (iii) HDT understands that an investment in the USPI-B Stock is an
illiquid investment, which means that (A) HDT must bear the economic risk of
investment in the USPI-B Stock for an indefinite period of time, since the
USPI-B Stock has not been registered under the Securities Act nor any state
securities laws and cannot be sold unless the USPI-B Stock is either
subsequently registered under the Securities Act and applicable state laws
(which is neither contemplated by nor required of USPI) or an exemption from
such registration is available, and (B) there is no established market for the
USPI-B Stock and that it is not anticipated that any public market for the
USPI-B Stock will develop in the near future.

converted into other securities (as hereinafter defined, the "Conversion
Securities") under certain circumstances. HDT acknowledges (A) that it has no
control over such conversion and (B) that the Conversion Securities will
constitute an illiquid investment, which means that (1) HDT must bear the
economic risk of investment in the Conversion Securities for an indefinite
period of time, since the Conversion Securities have not been registered under
the Securities Act nor any state securities laws and cannot be sold unless the
Conversion Securities are either subsequently registered under the Securities
Act and applicable state laws (which is neither contemplated by nor required of
the issuers of such securities) or an exemption from such registration is

         (b) CONFLICTS. The execution, delivery and performance of this
Agreement by USPI will not conflict with, result in any breach of or constitute

                                   ARTICLE II

                         ADDITIONAL INVESTMENTS IN USPE

      2.1. USPI INVESTMENTS IN USPE. USPI may invest additional sums in USPE at
any time and from time to time in one or more transactions. USPI plans to invest
a minimum of $100 million (including monies previously invested) in USPE subject
to approval, on a case by case basis, by the Board of Directors of USPI,
assuming such projects have reasonable returns, which generally shall be deemed
to occur if projects are available with acquisition multiples ranging from 4 to
7 times first year EBITDA of the project. USPI may infuse additional equity to
purchase certain strategic acquisitions above the mentioned multiples when
approved on a case-by-case basis by the Board of Directors of USPI. Investments
in USPE will take the form of debt to the extent of USPE's borrowing limits
under its Societe Generale Credit Facility dated March 3, 2000. The amount of
any investment which exceeds the borrowing limit would be in the form of an
equity investment. Equity investments made after the date of this Agreement by
USPI in USPE Shares shall constitute "Qualified Investments" to the extent that
the aggregate amount of such equity investments made after the date of this
Agreement is less than or equal to $70,247,336. USPE agrees to accept all
Qualified Investments, and to issue additional USPE Shares to USPI in
consideration for such Qualified Investments. The purchase price per additional
USPE Share will be equal to the weighted average share price on the most recent
$1,000,000 of capital raised through the sale of shares of USPI Common Stock
(including USPI A-Stock or USPI B-Stock, but excluding USPI B-Stock issued
pursuant to SECTION 1.1) to third parties (provided there has been $1,000,000 of
sales of such common stock within the 12-month period preceding the Qualified
Investment). If there has not been $1,000,000 of sales within the 12-month
period preceding the date of the Qualified Investment, then the most recent
$1,000,000 of sales shall be used to determine the purchase price, unless either
USPI or HDT objects to using the most recent sales, then USPI and HDT shall
jointly select a third party appraiser to determine the fair market value
purchase price for the USPE Shares. If USPI has made $70,247,336 in Qualified
Investments or if HDT's USPI B-Stock has been converted into USPE Shares, then
any further investments made by USPI in USPE shall not constitute Qualified

                                        4
<PAGE>
Investments, and such further investments may be on such terms and conditions,
including purchase price, as USPI and USPE shall determine.

      2.2. NOTICE OF QUALIFIED INVESTMENT. USPI shall give written notice of
each Qualified Investment to HDT within five days after the date of consummation
of such investment (each, a "Notice of Qualified Investment").

                                   ARTICLE III

                          CO-INVESTMENTS BY HDT IN USPI

      3.1. HDT CO-INVESTMENTS IN USPI. In connection with each Qualified
Investment, HDT may, but is not obligated to, invest additional sums in USPI by
purchasing additional shares of USPI-B Stock. Any such investments made after
the date of this Agreement by HDT in USPI-B Stock in compliance with this
Agreement shall constitute "HDT Co-Investments." HDT Co-Investments must be made
within 30 days after the date of the corresponding Qualified Investment. The
amount of each HDT Co-Investment shall be determined by HDT separately in its
discretion in connection with each separate Qualified Investment (subject in
each case to a minimum of 0% and a maximum of 8.0% of the Qualified Investment).
USPI agrees to accept all HDT Co-Investments, and to issue additional shares of
USPI-B Stock to HDT in consideration of such HDT Co-Investments at a purchase
price per share of USPI-B Stock equal to the purchase price per share paid for
the USPE Shares in the relevant Qualified Investment. USPI shall cooperate with
the reasonable due diligence requests of HDT by providing information and making
its management personnel available to answer questions. USPI shall provide HDT
with quarterly financial statements relating to its results of operations and
financial conditions. In connection with each HDT Co-Investment, HDT and USPI
agree to execute documentation containing representations, warranties and other
terms and conditions customary in this type of transaction (including
representations by HDT with respect to the matters addressed in SECTIONS 1.3(A),
B) AND (C), and representations by USPI with respect to the matters addressed in
SECTIONS 1.4(A), (B), (C) AND (D)), all of which must be acceptable to both
parties in their reasonable discretion. All HDT Co-Investments shall be made by
wire transfer to USPI of immediately available funds in dollars based upon the
Exchange Rate actually achieved by USPI in consummating the corresponding
Qualified Investment.

      3.2. LOANS TO FINANCE HDT INVESTMENTS.

         (a) On the date hereof, USPI shall make a recourse loan to HDT in the
amount of $811,093 to pay a portion of the Purchase Price pursuant to SECTION
1.1 hereof. Such loan shall be made pursuant to a Promissory Note substantially
in the form of EXHIBIT B attached hereto.

         (b) In connection with each HDT Co-Investment, USPI shall make a
recourse loan to HDT in order to finance a portion of such HDT Co-Investment. If
the HDT Co-Investment is less than or equal to 5.0% of the Qualified Investment,
then such loan shall be in the amount of up to 90% of the HDT Co-Investment. If
the HDT Co-Investment is greater than 5.0% (up to the

                                        5
<PAGE>
maximum of 8.0% of the Qualified Investment), then the loan shall be in a
principal amount of up to the sum of (i) 90% of the amount of HDT Co-Investment
up to 5.0%, and (ii) 75% of the HDT Co-Investment greater than 5.0%. Each such
loan shall be made pursuant to a Promissory Note substantially in the form of
EXHIBIT B attached hereto.

         (c) All such loans made pursuant to paragraphs (a) and (b) above shall
be guaranteed by the shareholders of HDT pursuant to Guaranty Agreements
substantially in the form of EXHIBIT C attached hereto, and secured by a pledge
of the USPI-B Stock pursuant to the Pledge Agreement substantially in the form
of EXHIBIT D attached hereto.

                                   ARTICLE IV

                              TRANSFER RESTRICTIONS

      4.1. INITIAL TRANSFER RESTRICTION. From and after the date hereof until
June 1, 2002, HDT shall not sell, transfer or otherwise dispose of any shares of
USPI-B Stock or USPE Shares (if the USPI B-Stock has been converted into USPE
Shares), except (i) upon conversion in accordance with the provisions of the
Certificate, (ii) pursuant to buy backs in accordance with ARTICLE V, or (iii)
with the prior written consent of USPI, which consent may be withheld in USPI's
sole and absolute discretion.

      4.2. RIGHT OF FIRST REFUSAL. After June 1, 2002, HDT may sell for cash all
or any portion of the USPI-B Stock or USPE Shares (if the USPI B-Stock has been
converted into USPE Shares) that it then holds pursuant to a bona fide offer
from an unrelated third party, subject to HDT's compliance with the following
provisions (provided that this SECTION 4.2 shall not apply to conversion of such
USPI-B Stock in accordance with the provisions of the Certificate or buy backs
in accordance with ARTICLE V);

         (a) HDT shall promptly deliver a notice of intention to sell (the "Sale
Notice") to USPI setting forth in reasonable detail the USPI-B Stock or USPE
Shares to be sold (the "Subject Securities"), attaching a photocopy of the bona
fide offer extended by the potential purchaser, which must be binding, and
indicating the price and the remaining conditions of the offer, the name of the
potential purchaser, as well as its ultimate controlling shareholder (to HDT's
knowledge).

         (b) Upon receipt of such Sale Notice, USPI shall have the first right
and option to elect to purchase at the price and on the terms stated in the Sale
Notice, all or part of the Subject Securities. In the event USPI shall elect to
purchase all or part of the Subject Securities, USPI shall so notify HDT in
writing (the "Election Notice") within 30 days after receipt by USPI of the Sale
Notice (the "Option Period").

         (c) Upon receipt of the Election Notice, HDT shall sell to USPI the
Subject Securities subject to such Election Notice at a price and on the terms
stated in the Sale Notice. The closing of such sale shall take place at the
offices of USPI no later than 30 days following the expiration of the

                                        6
<PAGE>
Option Period (or upon the expiration of such longer period required by law), or
at such other place or earlier date as may be mutually agreed by USPI and HDT.
At such closing, HDT shall deliver a certificate or certificates for the Subject
Securities to be sold, accompanied by stock powers duly authorized in blank,
against receipt of the purchase price therefor by wire transfer of immediately
available funds.

         (d) Any Subject Securities not sold pursuant to the provisions of this
SECTION 4.2 may be sold to the person identified in the related Sale Notice for
a period of 90 days following the expiration of the Option Period upon the terms
and conditions set forth in the Sale Notice. Any Subject Securities not sold to
such person on such terms during such 90-day period shall again be subject to
the restrictions contained in this SECTION 4.2.

      4.3. RESTRICTIVE LEGEND. Each certificate representing USPI-B Stock or
USPE Shares shall conspicuously bear the following legend until such time as the
USPI-B Stock or USPE Shares, as the case may be, represented thereby are no
longer subject to the provisions hereof

      THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD,
      TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS THEY HAVE BEEN REGISTERED
      UNDER THAT ACT OR AN EXEMPTION FROM REGISTRATION IS AVAILABLE. THE RIGHTS
      OF THE HOLDER OF THE SHARES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO
      THE TERMS AND CONDITIONS OF A STOCKHOLDERS AGREEMENT, DATED AS OF
      SEPTEMBER 26, 2000, AMONG THE ISSUER AND THE OTHER PARTIES THERETO, AS THE
      SAME MAY BE AMENDED, RESTATED, SUPPLEMENTED OR OTHERWISE MODIFIED FROM
      TIME TO TIME. COPIES OF SUCH AGREEMENT MAY BE OBTAINED AT NO COST BY
      WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE
      ISSUER.

                                    ARTICLE V

                                 BUY BACK RIGHTS

      If at any time prior to the occurrence of a Triggering Event (i) any
shareholder of HDT who provides services to USPE pursuant to a management
contract between HDT and USPE shall cease to provide services to USPE due to
either the shareholder's voluntary termination of employment or such person's
dismissal declared for just cause in accordance with Article 54 of the Spanish
Workers Statute, and if USPI and HDT do not agree on a replacement who shall
become a shareholder of HDT within 60 days after such discontinuation of
services, or (ii) any of HDT's capital shares shall ultimately be owned by a
person or entity other than a current shareholder of HDT or someone providing
services to USPE under a management contract (whether by judicial or
administrative executory proceeding, realization of a right of pledge or
otherwise), then, and in each such case, USPI shall have an option to purchase
that number of the shares of USPI-B Stock held

                                        7
<PAGE>
by HDT determined in accordance with the formula B-1 set forth in APPENDIX B at
a purchase price equal (on an "as converted" basis, as if USPI B-Stock was
converted into USPI Common Stock) to the weighted average share price on the
most recent $1,000,000 of capital raised through the sale of shares of USPI
Common Stock (including USPI A-Stock or USPI B-Stock, but excluding USPI B-Stock
issued pursuant to SECTION 1.1) to third parties (provided there has been
$1,000,000 of sales of such common stock within the 12-month period preceding
the date of exercise of the option). If there has not been $1,000,000 of sales
of such common stock within the 12-month period preceding the date of the
exercise of the option, then the most recent $1,000,000 of sales shall be used
to determine the purchase price, unless either USPI or HDT objects to using the
most recent sales, then USPI and HDT shall jointly select a third party
appraiser to determine the fair market value exercise price for the USPI
B-Stock. USPI shall notify HDT of its election to exercise the option within 90
days after USPI receives notice of such discontinuation of services or transfer
of ownership, and USPI shall consummate the option exercise within 30 days after
providing notification to HDT. Notwithstanding the foregoing, USPI shall not
have the option to purchase up to 20% of the outstanding USPI B-Stock which
would otherwise be subject to the option hereinabove provided if the other
shareholders of HDT who provide services to USPE pursuant to a management
contract acquire the underlying shares of HDT which give rise to the repurchase
option.

                                   ARTICLE VI

                                  EXIT PAYMENT

      6.1. EXIT PAYMENT. (a) Subject to the provisions of SECTION 6.1(B), an IPO
of either USPE or USPI has not occurred prior to the termination hereof, USPE
shall pay HDT an exit payment (the "Exit Payment") calculated in accordance with
SECTION 6.2 upon the occurrence of a Triggering Event at USPE (other than an
IPO).

         (b) If (i) HDT has converted its USPI B-Stock into USPE Shares prior to
the occurrence of an IPO of either USPE or USPI, and (ii) an IPO of USPE has not
occurred prior to the termination hereof, USPE shall pay HDT the Exit Payment
calculated in accordance with SECTION 6.2 upon the occurrence of a Triggering
Event at USPE (other than an IPO at USPE).

      6.2. CALCULATION OF EXIT PAYMENT.

         (a) If the total investment in USPE Shares made by USPI and HDT both
prior to and after the date of this Agreement (the "Total Investment") is equal
to or exceeds $100 million, the Exit Payment shall be calculated according to
the following table, as modified by subsection (c) below:

-------------------------------------------------------------------------------

         (b) If the Total Investment is less than $100 million, the Exit Payment
shall be calculated according to the table set forth above but such amount shall
be proportionately reduced by the ratio of the Total Investment to $100 million,
and thereafter reduced as specified in subsection (c) below.

         (c) The total amount of the Exit Payment to be paid will be the amount
resulting from subsection (a) or (b) above, as appropriate, minus an amount
calculated as follows: (1) $1,760,811 plus (2) with respect to each Qualified
Investment, the amount of such Qualified Investment multiplied by a percentage
equal to 7%.

                                   ARTICLE VII

                            PROVISIONS REGARDING HDT

      7.1. HDT SHAREHOLDERS AGREEMENT. HDT shall cause all of its present and
future shareholders (the "HDT Shareholders") to enter into and be bound by a
shareholders agreement (the "HDT Shareholders Agreement") reasonably acceptable
to USPI which limits transfers of HDT's capital shares. The provisions of the
HDT Shareholders Agreement dealing with transfers of HDT's capital shares may
not be amended without USPI's written consent, which shall not be unreasonably
withheld.

      7.2. HDT CHANGE OF CONTROL. If an HDT Change of Control shall occur, (i)
HDT's rights under SECTION 3.1 shall immediately terminate, (ii) the obligations
of USPI and USPE under SECTION 2.1 shall immediately terminate, and (iii) any
investments made by USPI in USPE after the date of such HDT Change of Control
(A) shall not constitute Qualified Investments and (B) may be made on such terms
and conditions, including purchase price, as USPI and USPE shall determine.

                                  ARTICLE VIII

                           SALE OF USPE SHARES BY USPI

      If at any time USPI intends to transfer, sell or dispose in any way of its
investment in USPE to an Unrelated Third Party in such a way as to cause a
Triggering Event at USPE, HDT shall have the right to sell all or part of the
USPE Shares that HDT would receive (or, as of such date, has received) upon
conversion of the USPI-B Stock pursuant to the provisions of the Certificate in
the economic conditions stated in the final sentence of this paragraph, in which
case USPI shall not proceed with the sale of its USPE Shares until and unless
the potential purchaser of its USPE Shares has effectively extended a binding
offer to HDT, as well, under the same terms and conditions as those offered to
USPI. To this effect, when HDT receives a notification in which it is informed
of USPI's intention to sell, transfer or dispose in any other way of its
investment in USPE to an Unrelated Third Party, HDT shall communicate its
intention of selling the USPE Shares it would receive upon conversion to the
acquiror within a maximum period of 15 days after such notification. The price
per share at which HDT shall exercise its right to sell USPE Shares will be the
price per share offered by the buyer to USPI, and payment and other conditions
shall be the same as those offered to USPI.

                                   ARTICLE IX

                                  MISCELLANEOUS

      9.1. TERMINATION. This Agreement shall terminate upon the earlier to occur
of (i) (A) if HDT has not converted its shares of USPI B-Stock into USPE Shares
as of the time a USPI or USPE Triggering Event occurs, at the time of the
occurrence of a USPI or USPE Triggering Event, or (B) if HDT has converted its
shares of USPI B-Stock into USPE Shares prior to the time a USPI or USPE
Triggering Event occurs, at the time of the occurrence of a USPE Triggering
Event, or (ii) the mutual agreement of the Parties.

      9.2 COUNTERPARTS; FAX SIGNATURES. This Agreement may be executed in any
number of counterparts, each of which will be deemed to be an original
agreement, but all of which will constitute one and the same agreement. Any
Party may execute and deliver this Agreement by an executed signature page
transmitted by a facsimile machine. If a Party transmits its signature page by a
facsimile machine, such Party will promptly thereafter deliver an originally
executed signature page to the other Parties, provided that any failure to
deliver such an originally executed signature page will not affect the validity,
legality, or enforceability of this Agreement.

understanding between the Parties and supersedes all prior agreements and
understandings, both written and oral, and all contemporaneous oral agreements
and understandings with respect to the subject matter of this Agreement,

      9.8 REPRESENTATION BY LEGAL COUNSEL. Each Party is a sophisticated person
that was advised by experienced legal counsel and other advisors in the
negotiation and preparation of this Agreement.

      9.9 SEVERABILITY. Any provision of this Agreement that is prohibited or
unenforceable in any jurisdiction will not invalidate the remaining provisions
of this Agreement or affect the validity or enforceability of such provision in
any other jurisdiction. In addition, any such prohibited or unenforceable
provision will be given effect to the extent possible in the jurisdiction where
such provision is prohibited or unenforceable.

      9.10 SUCCESSORS. This Agreement will be binding upon and will inure to the
benefit of each Party and its heirs, legal representatives, permitted assigns,
and permitted successors, provided that this Section will not permit the
assignment or other transfer of this Agreement, whether by operation of law, or
otherwise, if such assignment or other transfer is not otherwise permitted under
this Agreement.

      9.11 TIME OF THE ESSENCE. Time is of the essence in the performance of
this Agreement and all dates and periods specified in this Agreement.

      9.12 WAIVER. No provision of this Agreement will be considered waived
unless such waiver is in writing and signed by the Party that benefits from the
enforcement of such provision. No waiver of any provision in this Agreement,
however, will be deemed a waiver of a subsequent breach of such provision or a
waiver of a similar provision. In addition, a waiver of any breach or a failure
to enforce any term or condition of this Agreement will not in any way affect,
limit, or waive a Party's rights under this Agreement at any time to enforce
strict compliance thereafter with every term and condition of this Agreement.

      9.13 LANGUAGE. This Agreement has been signed in both English and Spanish
language versions. Both versions are valid, but in the event of any
inconsistency or ambiguity, the English version shall prevail.

      9.14 EUROPEAN HOLDING COMPANY. The Parties acknowledge that USPI may
choose to create an intermediate holding company that would be a wholly-owned
subsidiary of USPI and the holder of some or all of USPI's investments in USPE
("EuroHoldCo"). If USPI determines to create EuroHoldCo, the Parties agree to
execute and deliver such further agreements and instruments, including, without
limitation, amendments to this Agreement, as are necessary and appropriate in
order to permit the creation of EuroHoldCo, and, at the option of USPI, the
transfer of some or all

                                       12
<PAGE>
of USPI's investment in USPE to EuroHoldCo, while preserving in substance the
relative rights and benefits (including tax consequences) of the Parties
provided for in this Agreement. Without limiting the generality of the
foregoing, the Parties contemplate that the creation of EuroHoldCo would require
an amendment and restatement of this Agreement addressing, among other items,
the following issues: (i) the modification of SECTIONS 2.1 AND 2.2 to provide
for investments by EuroholdCo in USPE, (ii) the modification of the definition
of the term "Triggering Event" to include events occurring at or with respect to
EuroHoldCo, (iii) the creation of a definition of the "EuroHoldCo Conversion
Ratio", which would be similar in structure to the USPI Conversion Ratio, and
(iv) the inclusion of an IPO at EuroHoldCo in the first clause of SECTION 6.1.

      9.15 JUDGMENT CURRENCY. This is an international loan transaction in which
the specification of Spanish pesetas or U.S. dollars is of the essence, and the
stipulated currency shall in each instance be the currency of account and
payment in all instances. A payment obligation in one currency hereunder (the
"Original Currency") shall not be discharged by an amount paid in another
currency ("Other Currency"), whether pursuant to any judgment expressed in or
converted into the Other Currency or otherwise except to the extent that such
tender or recovery results in the effective receipt by the payee of the full
amount of the Original Currency payable to it under this Agreement.

      9.16 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations and
warranties contained herein shall survive the execution and delivery of this
Agreement and the Closing, regardless of any investigation at any time made by
or on behalf of any Party hereto.

      9.17 USPE OBLIGATIONS. Upon completion of the transaction contemplated by
SECTION 1.1 hereof, USPE shall become a wholly-owned subsidiary of USPI. USPI
has the legal capacity to cause, and it shall cause, USPE to meet all of its
obligations under this Agreement. With respect to USPE Shares issuable upon
conversion of the USPI B-Stock, USPI undertakes to transfer the applicable
number of USPI's USPE Shares to the holder of such converted USPI B-Stock or,
alternatively, to pass or cause to be passed a shareholders' resolution at USPE
in order to agree to a share capital increase in USPE to provide the applicable
number of USPE Shares which shall be subscribed by the holder of the converted
USPI B-Stock by means of a contribution in kind of such holder's converted USPI
B-Stock.

      9.18 TAX RESTRUCTURING. In the event HDT elects to convert the USPI
B-Stock into USPE Shares, then the Parties agree to consider structuring the
conversion as a redemption of HDT's USPI B-Stock in exchange for a market rate
promissory note of USPI. The USPI promissory note would be exchanged by HDT for
the USPE Shares. The foregoing transactions must be structured in such a manner
as to preserve in substance the relative rights and benefits (including tax
consequences) of the Parties provided for in this Agreement.

      All cross-references in each subdivision of this Article FOURTH refer to

      The following is a statement of the designations, and the powers,
preferences and rights, and the qualifications, limitations or restrictions
thereof, in respect of each class of stock of the Corporation:

                                       1.

                                 PREFERRED STOCK

      Except as otherwise expressly provided herein, all shares of Preferred
Stock shall be identical and shall entitle the holders thereof to the same
rights and privileges.

      1. Cumulative Dividends. The holders of shares of Series A Preferred Stock
and Series B Preferred Stock shall be entitled to receive, on April 30th of each
year beginning April 30, 2000, out of funds legally available for such purpose,
cash dividends at the rate of (x) $50.00 per share per annum on April 30, 2000
arid (y) $75.00 per share per annum thereafter, and no more, payable (as
determined from time to time by the Board of Directors) on each share of
Preferred Stock that shall then be outstanding (each annual period ended April
30th being referred to for the purposes of this subdivision I as a "Dividend
Period"). Such dividends shall be cumulative (so that if for any Dividend Period
such dividends are not paid or declared and set apart therefor, the deficiency
shall be paid, in whole or in part (without interest), on the next succeeding
dividend payment date on which the Corporation has any funds legally available
therefor) and shall accrue from and after the date of issue whether or not
declared and whether or not there are any funds of the Corporation legally
available for the payment of dividends. Accrued but unpaid dividends shall not
bear interest. The Board of Directors of the Corporation may fix a record date
for the determination of holders of Series A Preferred Stock and Series B
Preferred Stock entitled to receive payment of a dividend declared thereon,
which record date shall be no more than 60 days prior to the date fixed for the
payment thereof

      As long as any shares of Preferred Stock shall remain outstanding, in no
event (without the written consent of the holders of a majority of the
outstanding Preferred Stock) shall any dividend whatsoever be paid upon, nor any
distribution be made upon, any shares of Class A Common Stock, Class B Common
Stock or Common Stock, other than a dividend or distribution payable in shares
of Class A Common Stock, Class B Common Stock or Common Stock, as the case may
be, nor except for the repurchase of shares (x) from participants under any
stock option plans approved by a majority of the Board of Directors of the
Corporation, (y) pursuant to employment agreements or stock purchase agreements
with employees approved by the Board of Directors of the Corporation, and (z) of
Class B Common Stock pursuant to the Stockholders Agreement dated as of
September 26, 2000, by and among Health Dream Team, S.C., the Corporation and
United Surgical Partners Europe, S.L., as such may be amended from time to time
in accordance with the terms thereof (the "Stockholders Agreement"), shall any
shares of Class A Common Stock, Class B Common Stock or Common Stock be
purchased or redeemed by the Corporation, nor shall any moneys be paid to or
made available for a sinking fund for the purchase or redemption of shares of
any Class A Common Stock, Class B Common Stock or Common Stock, unless, in each
such case, accrued and unpaid dividends on all outstanding

                                       2
<PAGE>

shares of Preferred Stock for all prior Quarterly Payment Dates and Dividend
Periods shall have been declared and paid in full and the full dividend on all
outstanding shares of Preferred Stock for the then-current Quarterly Payment
Date and Dividend Period shall have been paid or declared and sufficient funds
for the payment thereof set apart, and any arrears or defaults in any redemption
of shares of Preferred Stock shall have been cured. In the event that the
Corporation shall at any time pay a dividend on the Class A Common Stock or
Common Stock (other than a dividend payable solely in shares of Class A Common
Stock or Common Stock) in accordance with this paragraph, it shall, at the same
time, pay to each holder of Series C Preferred Stock (in addition to any payment
such holder is entitled to receive pursuant to this paragraph 1), a dividend
equal to the dividend that would have been payable to such holder if the shares
of Series C Preferred Stock held by such holder had been converted into Class A
Common Stock or Common Stock, as the case may be, on the date of determination
of holders of Class A Common Stock or Common Stock entitled to receive such
dividend.

      2. Redemption. The shares of Series A Preferred Stock and Series B
Preferred Stock (collectively, the "Redeemable Preferred Stock") shall be
redeemable as follows:

      2A. Mandatory Redemption. Except as and to the extent expressly prohibited
by applicable law, the Corporation shall redeem (in the manner and with the
effect provided in subparagraphs 2C through 2E below) all shares of Redeemable
Preferred Stock which shall then be outstanding, on the earlier to occur of (i)
the consummation by the Corporation of an initial public offering of its Common
Stock registered under the Securities Act of 1933, as amended (an "Initial
Public Offering") or (ii) April 30, 2008. In case of the occurrence of any of
the following (each a "Change of Control Event"): (i) a consolidation or merger
of the Corporation with or into any other corporation (other than a merger which
will not result in more than 50% of the voting capital stock of the Corporation
outstanding immediately after the effective date of such merger being owned of
record or beneficially by persons other than the holders of such voting capital
stock immediately prior to such merger in the same proportions in which such
shares were held immediately prior to such merger), (ii) a sale of all or
substantially all of the properties and assets of the Corporation as an entirety
in a single transaction or in a series or related transactions to any other
person or (iii) the acquisition of "beneficial ownership" by any "person" or
"group" (other than Welsh, Carson, Anderson & Stowe VII, L.P. or its affiliates)
of voting stock of the Corporation representing more than 50% of the voting
power of all outstanding shares of such voting stock, whether by way of merger
or consolidation or otherwise, the Corporation shall, not later than 20 days
prior to the effective date of any such Change of Control Event, give notice
thereof to the holder or holders of shares of Redeemable Preferred Stock and, in
the event that within 15 days after receipt of such notice, any holder or
holders of shares of Redeemable Preferred Stock shall elect, by written notice
to the Corporation, to have any or all of its shares of Redeemable Preferred
Stock redeemed, the Corporation shall redeem the same (in the manner and with
the effect provided in subsections 2C through 2E below) not later than the
effective date and time of such Change of Control Event. In addition, at any
time on or after the second anniversary of the date on which shares of Series B
Preferred Stock are first issued, the Corporation shall, not later than 30 days
after receipt of written notice from any holder of shares of Series B Preferred
Stock requesting redemption of any or all of its shares of Series B Preferred
Stock, redeem such shares of Series B Preferred Stock (in the manner and with
the effect provided in subparagraphs 2C through 2E below).

                                       3
<PAGE>

      As used herein, (i) the terms "person" and "group" shall have the meaning
set forth in Section 1 3(d)(3) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), whether or not applicable, (ii) the term
"beneficial owner" shall have the meaning set forth in Rules 1 3d-3 and 1 3d-S
under the Exchange Act, whether or not applicable, except that a person shall be
deemed to have "beneficial ownership" of all shares that any such person has the
right to acquire, whether such right is exercisable immediately or only after
the passage of time or upon the occurrence of certain events, and (iii) any
"person" or "group" will be deemed to beneficially own any voting stock of the
Corporation so long as such person or group beneficially owns, directly or
indirectly, in the aggregate a majority of the voting stock of a registered
holder of the voting stock of the Corporation.

      2B. Optional Redemption. The Corporation may, in its sole discretion,
redeem at any time and from time to time (in the manner and with the effect
provided in subparagraphs 2C through 2E below), any whole number of shares of
Redeemable Preferred Stock. Any date on which the Corporation elects to redeem
shares of Redeemable Preferred Stock as provided in this subparagraph 2B and
each date on which the Corporation shall be required to redeem shares of
Redeemable Preferred Stock as provided in subparagraph 2A above shall be
referred to as a "Redemption Date."

      2C. Redemption Price; Notice of Redemption. The Redeemable Preferred Stock
to be redeemed on a Redemption Date shall be redeemed by paying for each share
the sum of (i) $1,000, plus (ii) an amount equal to dividends accrued and unpaid
thereon from the date of issuance of such share of Redeemable Preferred Stock to
such Redemption Date, the sum of (i) and (ii) being herein sometimes referred to
as the "Redemption Price". Not less than 20 days before such Redemption Date,
written notice shall be given by mail, postage prepaid to the holders of record
of the Redeemable Preferred Stock to be redeemed, such notice to be addressed to
each such stockholder at his post office address as shown by the records of the
Corporation, specifying the number of shares to be redeemed, the paragraph or
paragraphs of this Certificate of Incorporation pursuant to which such
redemption shall be made, the Redemption Price and the place and date of such
redemption, which date shall not be a day on which banks in the City of New York
are required or authorized to close. If such notice of redemption shall have
been duly given and if on or before such Redemption Date the funds necessary for
redemption shall have been set aside so as to be and continue to be available
therefor, then, notwithstanding that any certificate for shares of Redeemable
Preferred Stock to be redeemed shall not have been surrendered for cancellation,
after the close of business on such Redemption Date, the shares so called for
redemption shall no longer be deemed outstanding, the dividends thereon shall
cease to accrue, and all rights with respect to such shares shall forthwith
after the close of business on the Redemption Date, cease, except only the right
of the holders thereof to receive, upon presentation of the certificate
representing shares so called for redemption, the Redemption Price therefor,
without interest thereon.

      2D. Redeemed or Otherwise Acquired Shares to Be Retired. Any shares of the
Redeemable Preferred Stock redeemed pursuant to this paragraph 2 or otherwise
acquired by the Corporation in any manner whatsoever shall be permanently
retired and shall not under any circumstances be reissued; and the Corporation
may from time to time take such appropriate corporate action as may be necessary
to reduce the number of authorized shares of Redeemable Preferred Stock
accordingly.

                                       4
<PAGE>

      2E. Shares to be Redeemed. In case of the redemption, for any reason, of
only part of the outstanding shares of Redeemable Preferred Stock on a
Redemption Date, all shares of Redeemable Preferred Stock to be redeemed shall
be selected pro rata, and there shall be so redeemed from each registered holder
in whole shares, as nearly as practicable to the nearest whole share, that
proportion of all the shares to be redeemed which the number of shares held of
record by such holder bears to the total number of shares of Redeemable
Preferred Stock at the time outstanding. Any shares of Redeemable Preferred
Stock that are designated for redemption on a Redemption Date and are not so
redeemed shall be redeemed as soon thereafter as possible and in the manner in
which shares are otherwise redeemed on a Redemption Date, and, in such event, as
provided in this subdivision I, dividends shall continue to accrue on such
shares.

      3. Liquidation. Upon any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, the holders of the shares of
Series A Preferred Stock and the holders of the shares of Series B Preferred
Stock shall be entitled, before any distribution or payment is made upon any
Class A Common Stock, Class B Common Stock or Common Stock, to be paid an amount
equal to $1,000 per share plus any accrued but unpaid dividends, and the holders
of the shares of Series C Preferred Stock shall be entitled before any
distribution or payment is made upon any Class A Common or Common Stock to be
paid an amount equal to the Series C Preferred Liquidation Value with respect to
each outstanding share plus any accrued but unpaid dividends thereon (such
amounts being sometimes referred to as the "Preferred Liquidation Payments"). If
upon such liquidation, dissolution or winding up of the Corporation, whether
voluntary or involuntary, the assets to be distributed among the holders of the
Preferred Stock of the Corporation shall be insufficient to permit payment to
such holders of the full amount of the Preferred Liquidation Payments, then the
entire assets of the Corporation to be so distributed shall be distributed
ratably per share among the holders of Preferred Stock in proportion to the full
per share amounts to which they respectively are entitled. Upon any such
liquidation, dissolution or winding up of the Corporation, after the holders of
Preferred Stock shall have been paid in full the preferential amounts to which
they shall be entitled as provided herein, the remaining net assets of the
Corporation shall be distributed to the holders of Class A Common Stock, Class B
Common Stock and Common Stock in accordance with this Certificate of
Incorporation, Written notice of such liquidation, dissolution or winding up,
stating a payment date, the amount of the Preferred Liquidation Payments to be
made pursuant hereto and the place where said Preferred Liquidation Payments
shall be payable shall be given by mail, postage prepaid, not less than 30 days
prior to the payment date stated therein to the holders of record of the
Preferred Stock, such notice to be addressed to each such holder at his post
office address as shown by the records of the Corporation; provided, however,
that failure to give notice pursuant to this sentence shall not invalidate the
action involved. A Change of Control Event shall not, for purposes of this
paragraph 3, be deemed a liquidation, dissolution or winding up of the
Corporation,

      "Series C Preferred Liquidation Value" determined as of any date shall
mean, in respect of each share of Series C Preferred Stock, an amount equal to
$1,000 (appropriately adjusted to reflect stock splits and combinations and
stock dividends, the "Initial Purchase Price") plus an amount equal to seven
percent (7%) of the Initial Purchase Price, compounded quarterly on each of
March 31, June 30, September 30 and December 31.

      4. Conversion of Convertible Preferred Stock.

      4A(l) Optional Conversion of Series B Preferred Stock. At any time on or
after the second anniversary of the date on which shares of Series B Preferred
Stock are first issued, subject to and upon compliance with the provisions of
this paragraph 4, the holder of any share or shares of Series B Preferred Stock
shall have the right, at its option, to convert any such shares of Series B
Preferred Stock (except that upon any liquidation, dissolution or winding up of
the Corporation or upon any redemption of the Series B Preferred Stock in
accordance with paragraph 2, the right of conversion shall terminate at the
close of business on the last full business day next preceding the date fixed
for payment of the amount distributable on Series B Preferred Stock or payable
with respect thereto) into such number of fully paid and non-assessable whole
shares of Class A Common Stock as is obtained by multiplying the number of
shares of Series B Preferred Stock so to be converted by $1,000 (plus any
accrued and unpaid per share dividends through the time of conversion) and
dividing the result by the greater of (x) $2.00 (such price, or such price as
last adjusted hereunder, the "Series B Base Conversion Price") and (y) the fair
market value per share of Class A Common Stock at the time of conversion as
determined in good faith by the Board of Directors of the Corporation. Such
rights of conversion shall be exercised by the holder thereof by giving written
notice that the holder elects to convert a stated number of shares of Series B
Preferred Stock into Class A Common Stock and by surrender of a certificate or
certificates for the shares so to be converted to the Corporation at its
principal office (or such other office or agency of the Corporation as the
Corporation may designate by notice in writing to the holder or holders of the
Series B Preferred Stock) at any time during its usual business hours on the
date set forth in such notice, together with a statement of the name or names
(with address), subject to compliance with applicable laws to the extent such
designation shall involve a transfer, in which the certificate or certificates
for shares of Class A Common Stock shall be issued,

      4A(2) Optional Conversion of Series C Preferred Stock. At any time on or
after the date on which shares of Series C Preferred Stock are first issued,
subject to and upon compliance with the provisions of this paragraph 4, the
holder of any share or shares of Series C Preferred Stock shall have the right,
at its option, to convert any such shares of Series C Preferred Stock (except
that upon any liquidation, dissolution or winding up of the Corporation or upon
any redemption of the Series C Preferred Stock in accordance with paragraph 2,
the right of conversion shall terminate at the close of business on the last
full business day next preceding the date fixed for payment of the amount
distributable on Series C Preferred Stock or payable with respect thereto) into
such number of fully paid and non-assessable whole shares of Class A Common
Stock as is obtained by multiplying the number of shares of Series C Preferred
Stock so to be converted by the Series C Preferred Liquidation Value and
dividing the result by $3.50, or by the conversion price as last adjusted and in
effect at the date any share of shares of Series C Preferred Stock are
surrendered for conversion (such price, or such price as last adjusted
hereunder, the "Series C Conversion Price's). Such rights of conversion shall be
exercised by the holder thereof by giving written notice that the holder elects
to convert a stated number of shares of Series C Preferred Stock into Class A
Common Stock and by surrender of a certificate or certificates for the shares so
to be converted to the Corporation at its principal office (or such other office
or agency of the Corporation as the Corporation may designate by notice in
writing to the holder or holders of the Series C Preferred Stock) at any time
during its usual business hours on the date set forth in such notice, together
with a statement of the name or names (with address), subject to compliance

                                       6
<PAGE>

with applicable laws to the extent such designation shall involve a transfer, in
which the certificate or certificates for shares of Class A Common Stock shall
be issued.

      4B. Issuance of Certificates: Time Conversion Effected. Promptly after the
receipt by the Corporation of a written notice referred to in subparagraph 4A(1)
or (2) and surrender of the certificate or certificates for the share or shares
of the Convertible Preferred Stock to be converted, the Corporation shall issue
and deliver, or cause to be issued and delivered, to the holder, registered in
such name or names as such holder may direct, subject to compliance with
applicable laws to the extent such designation shall involve a transfer, a
certificate or certificates for the number of whole shares of Class A Common
Stock issuable upon the conversion of such share or shares of Convertible
Preferred Stock. To the extent permitted by law, such conversion shall be deemed
to have been effected immediately prior to the close of business on the day the
certificate or certificates for such share or shares shall have been surrendered
as aforesaid, and at such time the rights of the holder of such share or shares
of Convertible Preferred Stock shall cease, and the person or persons in whose
name or names any certificate or certificates for shares of Class A Common Stock
shall be issuable upon such conversion shall be deemed to have become the holder
or holders of record of the shares represented thereby.

      4C. Fractional Shares Dividends: Partial Conversion. No fractional shares
shall be issued upon conversion of the Convertible Preferred Stock into Class A
Common Stock. In ease the number of shares of Convertible Preferred Stock
represented by the certificate or certificates surrendered pursuant to
subparagraph 4A(l) or (2) exceeds the number of shares converted, the
Corporation shall, upon such conversion, execute and deliver to the holder
thereof, at the expense of the Corporation, a new certificate or certificates
for the number of shares of Convertible Preferred Stock, represented by the
certificate or certificates surrendered which arc not to be converted. If any
fractional interest in a share of Class A Common Stock would, except for the
provisions of the first sentence of this subparagraph 4C, be deliverable upon
any such conversion, the Corporation, in lieu of delivering the fractional share
thereof, shall pay to the holder surrendering the Convertible Preferred Stock
for conversion an amount in cash equal to the current fair value of such
fractional interest as determined in good faith by the Board of Directors of the
Corporation.

      4D. Adjustment of Series C Conversion Price Upon Issuance of Common Stock.
Except as provided in subparagraph 4F hereof, if and whenever the Corporation
shall issue or sell, or is in accordance with subparagraphs 4D(1) through 4D(5)
deemed to have issued or sold, any shares of its Common Stock or Class A Common
Stock for a consideration per share less than the Series C Conversion Price in
effect immediately prior to the time of such issue or sale, then, forthwith, the
Series C Conversion Price shall be reduced to the price (calculated to the
nearest cent) determined by dividing (x) an amount equal to the sum of (1) the
number of shares of Common Stock outstanding immediately prior to such issue or
sale (including as outstanding all shares of Common Stock issuable upon
conversion of (i) outstanding Class A Common Stock, Series B Preferred Stock and
Series C Preferred Stock and (ii) the Corporation's Convertible Promissory Note
dated June 1, 1999 issued to Baylor Health Services) multiplied by the then
existing Series C Conversion Price, and (2) the consideration, if any, received
by the Corporation upon such issue or sale, by (y) the total number of shares of
Common Stock outstanding immediately after such issue or sale (including as
outstanding all shares of Common Stock issuable upon conversion of (i)
outstanding Class A Common Stock, Series B Preferred

                                       7
<PAGE>

Stock and Series C Preferred Stock and (ii) the Corporation's Convertible
Promissory Note dated June 1, 1999 issued to Baylor Health Services, without
giving effect to any adjustment in the number of shares so issuable by reason of
such issue or sale).

      For purposes of this subparagraph 4D, the following subparagraphs 4D(1) to
4D(7) shall also be applicable:

      4D(1). Issuance of Rights or Options. In case at any time the Corporation
shall in any manner grant any rights to subscribe for or to purchase, or any
options for the purchase of, Common Stock, Class A Common Stock or any stock or
securities convertible into or exchangeable for Common Stock or Class A Common
Stock (such rights or options being herein called "Options" and such convertible
or exchangeable stock or securities being herein called "Convertible
Securities") whether or not such Options or the right to convert or exchange any
such Convertible Securities are immediately exercisable, and the price per share
for which Common Stock or Class A Common Stock, as the case may be, is issuable
upon the exercise of such Options or upon conversion or exchange of such
Convertible Securities (determined by dividing (i) the total amount, if any,
received or receivable by the Corporation as consideration for the granting of
such Options, plus the minimum aggregate amount of additional consideration
payable to the Corporation upon the exercise of all such Options, plus, in the
case of such Options which relate to Convertible Securities, the minimum
aggregate amount of additional consideration, if any, payable upon the issue or
sale of such Convertible Securities and upon the conversion or exchange thereof,
by (ii) the total maximum number of shares of Common Stock or Class A Common
Stock issuable upon the exercise of such Options or upon the conversion or
exchange of all such Convertible Securities issuable upon the exercise of such
Options) shall be less than the Series C Conversion Price in effect immediately
prior to the time of the granting of such Options, then the total maximum number
of shares of Common Stock or Class A Common Stock issuable upon the exercise of
such Options or upon conversion or exchange of the total maximum amount of such
Convertible Securities issuable upon the exercise of such Options shall be
deemed to have been issued for such price per share as of the date of granting
of such Options and thereafter shall be deemed to be outstanding. Except as
otherwise provided in subparagraph 4E(3), no adjustment of the Series C
Conversion Price shall be made upon the actual issue of such Common Stock or
Class A Common Stock or of such Convertible Securities upon exercise of such
Options or upon the actual issue of such Common Stock or Class A Common Stock,
as the case may be, upon conversion or exchange of such Convertible Securities.

      4D(2). Issuance of Convertible Securities. In case the Corporation shall
in any manner issue (whether directly or by assumption in a merger or otherwise)
or sell any Convertible Securities, whether or not the rights to exchange or
convert thereunder are immediately exercisable, and the price per share for
which Common Stock or Class A Common Stock is issuable upon such conversion or
exchange (determined by dividing (i) the total amount received or receivable by
the Corporation as consideration for the issue or sale of such Convertible
Securities, plus the minimum aggregate amount of additional consideration, if
any, payable to the Corporation upon the conversion or exchange thereof, by (ii)
the total maximum number of shares of Common Stock and Class A Common Stock
issuable upon the conversion or exchange of all such Convertible Securities)
shall be less than the Series C Conversion Price in effect immediately prior to
the time of such issue or sale, then the total maximum number of shares of

                                       8
<PAGE>

Common Stock or Class A Common Stock issuable upon conversion or exchange of all
such Convertible Securities shall be deemed to have been issued for such price
per share as of the date of the issue or sale of such Convertible Securities and
thereafter shall be deemed to be outstanding, provided that (a) except as
otherwise provided in subparagraph 4D(3) below, no adjustment of the Series C
Conversion Price shall be made upon the actual issue of such Common Stock or
Class A Common Stock, as the case maybe, upon conversion or exchange of such
Convertible Securities, and (b) if any such issue or sale of such Convertible
Securities is made upon exercise of any Option to purchase any such Convertible
Securities for which adjustments of the Series C Conversion Price have been or
are to be made pursuant to other provisions of this subparagraph 4D, no further
adjustment of the Series C Conversion Price shall be made by reason of such
issue or sale.

      4D(3). Change in Option Price or Conversion Rate. If (i) the purchase
price provided for in any Option referred to in subparagraph 4D(l), (ii) the
additional consideration, if any, payable upon the conversion or exchange of any
Convertible Securities referred to in subparagraph 4D(1) or 4D(2) or (iii) the
rate at which any Convertible Securities referred to in subparagraph 4D(1) or
4D(2) are convertible into or exchangeable for Common Stock or Class A Common
Stock shall change at any time (in each case other than under or by reason of
provisions designed to protect against dilution), then the Series C Conversion
Price in effect at the time of such event shall, as required, forthwith be
readjusted to such Series C Conversion Price which would have been in effect at
such time had such Options or Convertible Securities still outstanding provided
for such changed purchase price, additional consideration or conversion rate, as
the case may be, at the time initially granted, issued or sold; and on the
expiration of any such Option or the termination of any such right to convert or
exchange such Convertible Securities, the Series C Conversion Price then in
effect hereunder shall, as required, forthwith be increased to the Series C
Conversion Price which would have been in effect at the time of such expiration
or termination had such Option or Convertible Securities, to the extent
outstanding immediately prior to such expiration or termination, never been
issued, and the Common Stock or Class A Common Stock, as the case maybe,
issuable thereunder shall no longer be deemed to be outstanding. If the purchase
price provided for in any such Option referred to in subparagraph 4D( 1) or the
rate at which any Convertible Securities referred to in subparagraph 4D(1) or
4D(2) are convertible into or exchangeable for Common Stock or Class A Common
Stock shall be reduced at any time under or by reason of provisions with respect
thereto designed to protect against dilution, then, in case of the delivery of
Common Stock or Class A Common Stock upon the exercise of any such Option or
upon conversion or exchange of any such Convertible Securities, the Series C
Conversion Price then in effect hereunder shall, as required, forthwith be
adjusted to such respective amount as would have been obtained had such Option
or Convertible Securities never been issued as to such Common Stock or Class A
Common Stock, as the case may be, and had adjustments been made upon the
issuance of the shares of Common Stock or Class A Common Stock delivered as
aforesaid, but only if as a result of such adjustment the Series C Conversion
Price then in effect hereunder is thereby reduced.

      4D(4). Stock Dividends. In case the Corporation shall declare a dividend
or make any other distribution upon any stock of the Corporation payable in
Common Stock, Class A Common Stock, Options or Convertible Securities, any
Common Stock, Class A Common Stock, Options or Convertible Securities, as the
case may be, issuable in payment of such dividend or distribution shall be
deemed to have been issued or sold without consideration, and the Series C

                                       9
<PAGE>

Conversion Price shall be reduced as if the Corporation had subdivided its
outstanding shares of Common Stock and Class A Common Stock into a greater
number of shares, as provided in subparagraph 4E hereof.

      4D(5). Consideration for Stock. In case any shares of Common Stock, Class
A Common Stock, Options or Convertible Securities shall be issued or sold for
cash, the consideration received therefor shall be deemed to be the amount
received by the Corporation therefor, without deduction therefrom of any
expenses incurred or any underwriting commissions or concessions paid or allowed
by the Corporation in connection therewith. In case any shares of Common Stock,
Class A Common Stock, Options or Convertible Securities shall be issued or sold
for a consideration other than cash, the amount of the consideration other than
cash received by the Corporation shall be deemed to be the fair value of such
consideration as determined in good faith by the Board of Directors of the
Corporation, without deduction therefrom of any expenses incurred or any
underwriting commissions or concessions paid or allowed by the Corporation in
connection therewith, In case any Options shall be issued in connection with the
issue and sale of other securities of the Corporation, together comprising one
integral transaction in which no specific consideration is allocated to such
Options by the Corporation, such Options shall be deemed to have been issued
without consideration.

      4D(6). Treasury Shares. The number of shares of Common Stock and Class A
Common Stock outstanding at any given time shall not include shares owned or
held by or for the account of the Corporation, and the disposition of any such
shares shall be considered an issue or sale of Common Stock or Class A Common
Stock for the purposes of this subparagraph 4D.

      4D(7). Record Date. In case the Corporation shall take a record of the
holders of its Common Stock or Class A Common Stock for the purpose of entitling
them (i) to receive a dividend or other distribution payable in Common Stock,
Class A Common Stock, Options or Convertible Securities, or (ii) to subscribe
for or purchase Common Stock, Class A Common Stock, Options or Convertible
Securities, then such record date shall be deemed to be the date of the issue or
sale of the shares of Common Stock or Class A Common Stock, as the case may be,
deemed to have been issued or sold upon the declaration of such dividend or the
making of such other distribution or the date of the granting of such right of
subscription or purchase, as the case maybe, provided that such shares of Common
Stock or Class A Common Stock, as the case may be, shall in fact have been
issued or sold.

      4E. Subdivision or Combination of Stock. In case the Corporation shall at
any time subdivide its outstanding shares of Class A Common Stock into a greater
number of shares or shall declare or pay a dividend on its outstanding shares of
Class A Common Stock payable in shares of Class A Common Stock, then in each
case the Series B Base Conversion Price and the Series C Base Conversion Price
shall be similarly reduced, and conversely, in case the outstanding shares of
Class A Common Stock of the Corporation shall be combined into a smaller number
of shares, the Base Conversion Price shall be similarly increased.

      4F Certain Issues of Common Stock Excepted. Anything herein to the
contrary notwithstanding, the Corporation shall not be required to make any
adjustment of the Series C Conversion Price upon the occurrence of any of the
following events: (i) the issuance of Class A Common Stock upon conversion of
outstanding shares of Series B Preferred Stock or Series C

                                       10
<PAGE>

Preferred Stock, (ii) the issuance and sale of, or grant of options to purchase
shares of Common Stock or Class A Common Stock to employees and advisors of the
Corporation pursuant to the Corporation's stock option plan or otherwise
approved by the Board of Directors of the Company, (iii) the issuance of Common
Stock upon conversion of outstanding shares of Class B Common Stock, and (iv)
the issuance and sale of shares of Class B Common Stock pursuant to the
Stockholders Agreement.

      4G. Reorganization. Reclassification. Merger of Sale. If any capital
reorganization or reclassification of the capital stock of the Corporation shall
be effected in such a way (including, without limitation, by way of
consolidation or merger) that holders of Class A Common Stock shall be entitled
to receive stock, securities or assets with respect to or in exchange for Class
A Common Stock, then, as a condition of such reorganization or reclassification,
lawful and adequate provision shall be made whereby each holder of a share or
shares of Convertible Preferred Stock shall thereafter have the right to
receive, upon the basis and upon the terms and conditions specified herein and
in lieu of the shares of Class A Common Stock of the Corporation immediately
theretofore receivable upon the conversion of such share or shares of
Convertible Preferred Stock, such shares of stock, securities or assets as may
be issued or payable with respect to or in exchange for a number of outstanding
shares of such Class A Common Stock equal to the number of shares of such stock
immediately theretofore so receivable had such reorganization or
reclassification not taken place, and in any such case appropriate provision
shall be made with respect to the rights and interests of such holder to the end
that the provisions hereof shall thereafter be applicable, as nearly as may be,
in relation to any shares of stock, securities or assets thereafter deliverable
upon the exercise of such conversion rights. In the event of a merger or
consolidation of the Corporation as a result of which a greater or lesser number
of shares of common stock of the surviving corporation are issuable to holders
of Class A Common Stock of the Corporation outstanding immediately prior to such
merger or consolidation, the Series B Base Conversion Price and the Series C
Base Conversion Price shall be adjusted in the same manner as though there were
a subdivision or combination of the outstanding shares of Class A Common Stock
of the Corporation. The Corporation will not effect any such consolidation or
merger, or any sale of all or substantially all its assets and properties,
unless prior to the consummation thereof the successor corporation (if other
than the Corporation) resulting from such consolidation or merger or the
corporation purchasing such assets shall assume by written instrument executed
and mailed or delivered to each holder of shares of Convertible Preferred Stock
at the last address of such holder appearing on the books of the Corporation,
the obligation to deliver to such holder such shares of stock, securities or
assets as, in accordance with the foregoing provisions, such holder may be
entitled to receive.

      4H. Notice of Adjustment. Upon any adjustment made pursuant to 4C or 4D,
then and in each such case the Corporation shall give written notice thereof, by
first class mail, postage prepaid, addressed to each holder of shares of
Convertible Preferred Stock at the address of such holder as shown on the books
of the Corporation, which notice shall state the number of shares of Class A
Common Stock or other securities, cash or property issuable upon conversion of
the Convertible Preferred Stock resulting from such adjustment, setting forth in
reasonable detail the method of calculation and the facts upon which such
calculation is based.

                                       11
<PAGE>

      4I. Stock to be Reserved. The Corporation will at all times reserve and
keep available out of its authorized but unissued Class A Common Stock, solely
for the purpose of issuance upon the conversion of the Convertible Preferred
Stock as herein provided, such number of shares of Class A Common Stock as shall
then be issuable upon the conversion of all outstanding shares of Convertible
Preferred Stock, All shares of Class A Common Stock which shall be so issued
shall be duly and validly issued and fully paid and non-assessable and free from
all taxes, liens and charges arising out of or by reason of the issue thereof.
The Corporation will take all such action within its control as may be necessary
on its part to assure that all such shares of Class A Common Stock may be so
issued without violation of any applicable law or regulation, or of any
requirements of any national securities exchange upon which the Class A Common
Stock of the Corporation may be listed.

      4J. No Reissuance of Convertible Preferred Stock. Shares of Convertible
Preferred Stock which are converted into shares of Class A Common Stock as
provided herein shall not be reissued.

      4K. Issue Tax. The issuance of certificates for shares of Class A Common
Stock upon conversion of the Convertible Preferred Stock shall be made without
charge to the holders thereof for any issuance tax in respect thereof, provided
that the Corporation shall not be required to pay any tax which may be payable
in respect of any transfer involved in the issuance and delivery of any
certificate in a name other than that of the holder of the Convertible Preferred
Stock which is being converted.

      4L. Closing of Books. The Corporation will at no time close its transfer
books against the transfer of any Convertible Preferred Stock or of any shares
of Class A Common Stock issued or issuable upon the conversion of any shares of
Convertible Preferred Stock in any manner which interferes with the timely
conversion of such Convertible Preferred Stock.

      4M(1). Definition of Class A Common Stock. As used in this paragraph 4,
the term "Class A Common Stock" shall mean and include the Corporation's
authorized Class A Common Stock, $.01 par value, as constituted on the date of
filing of this Certificate of Amendment to the Certificate of Incorporation and
shall also include any capital stock of any class of the Corporation thereafter
authorized which shall not be limited to a fixed sum or percentage of par value
in respect of the rights of the holders thereof to participate in dividends or
in the distribution of assets upon the voluntary or involuntary liquidation,
dissolution or winding up of the Corporation; provided that the shares of Class
A Common Stock receivable upon conversion of shares of the Convertible Preferred
Stock, or in case of any reorganization or reclassification of the outstanding
shares thereof, the stock, securities or assets provided for in subparagraphs 4C
and 4D, shall include only shares designated as Class A Common Stock of the
Corporation on June 1, 2000.

      4M(2). Definition of Common Stock. As used in this paragraph 4, the term

the holders thereof to participate in dividends or in the distribution of assets
upon the

                                       12
<PAGE>

voluntary or involuntary liquidation, dissolution or winding up of the
Corporation; provided that the shares of Common Stock receivable upon conversion
of shares of the Convertible Preferred Stock, or in case of any reorganization
or reclassification of the outstanding shares thereof, the stock, securities or
assets provided for in subparagraphs 4C and 4D, shall include only shares
designated as Common Stock of the Corporation on June 1,2000.

      5. Restrictions. At any time when shares of Preferred Stock are
outstanding, except where the vote or written consent of the holders of a
greater number of shares of the Corporation is required by law or by this
Certificate of Incorporation, and in addition to any other vote required by law,
without the prior consent of the holders of a majority of the outstanding
Preferred Stock, given in person or by proxy, either in writing or at a special
meeting called for that purpose, at which meeting the holders of the shares of
such Preferred Stock shall vote together as a class:

      (a) The Corporation will not (i) create or authorize the creation of any
additional class or series of shares unless the same ranks junior to the
Preferred Stock as to the distribution of assets upon the liquidation,
dissolution or winding up of the Corporation and as to the distribution of
dividends, (ii) increase the authorized amount of the Preferred Stock or the
authorized amount of any additional class or series of shares unless the same

security convertible into shares of Preferred Stock or into shares of any other
class or series unless the same ranks junior to the Preferred Stock as to the
distribution of assets upon the liquidation, dissolution or winding up of the
Corporation and as to the distribution of dividends, in each such case whether
any such creation or authorization or increase shall be by means of amendment of
the Certificate of Incorporation, merger, consolidation or otherwise.

      (b) The Corporation will not amend, alter or repeal the Corporation's
Certificate of Incorporation or By-laws in any manner, or file any directors'
resolutions pursuant to Section 151(g) of the General Corporation Law of the

affects the respective preferences, qualifications, special or relative rights
or privileges of the Preferred Stock or which in any manner adversely affects
the Preferred Stock or the holders thereof. In addition, no action shall be
taken that would adversely alter or change the powers, preferences or special
rights of one, series of Preferred Stock, but not so affect all of the Preferred
Stock, without the consent of the holders of a majority of the outstanding stock
of such series of Preferred Stock voting separately as a class.

      In addition, no such action shall be taken that would have the effect of
creating any additional differences between the respective preferences,
qualifications, special or relative rights or privileges of the Series A
Preferred Stock, the Series B Preferred Stock and the Series C Preferred Stock
without the consent of the holders of a majority of the outstanding Series A
Preferred Stock, the consent of the holders of a majority of the outstanding
Series B Preferred Stock and the consent of the holders of a majority of the
outstanding Series C Preferred Stock, voting separately.

      (c) The Corporation will not enter into any transaction that will result

Incorporation, the holders of Series C Preferred Stock shall vote together with
the holders of Common Stock on all matters to be voted on by the stockholders of
the Corporation, and each share of Series C Preferred Stock shall entitle the
holder thereof to such number of votes per share on each such action as shall
equal the number of shares of Class A Common Stock (including fractions of a
share) into which each share of Series C Preferred Stock is then convertible.

                                       II.

Class A Common Stock and Class B Common Stock shall be identical and shall
entitle the holders thereof to the same rights and privileges,

Common Stock and Common Stock shall be entitled to receive such dividends as
from time to time may be declared by the Board of Directors of the Corporation
out of any funds legally available therefor, subject to the provisions of
subdivision I above with respect to the rights of holders of the Preferred
Stock. The Corporation shall declare a dividend on the Class A Common Stock and
Class B Common Stock on each occasion that dividends are declared on the Common
Stock of the Corporation. No dividend shall be paid on or declared and set apart
for the shares of any class of common stock for any dividend period unless at
the same time a like proportionate dividend for the same dividend period shall
be paid on or declared and set apart for the shares and all other classes of
common stock of the Corporation. The holders of shares of Class A Common Stock
and Common Stock shall receive dividends in accordance with the number of shares
of Class A Common Stock or Common Stock then outstanding. Each holder of shares
of Class B Common Stock shall receive a dividend equal to the dividend that
would have been payable to such holder if the shares of Class B Common Stock had
been converted into Common Stock on the date of determination of holders of
Common Stock entitled to receive such dividend.

      2. Liquidation. Upon any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, (i) pursuant to and as more
particularly described in paragraph 4, all shares of Class B Common Stock shall
automatically convert into the number of shares of Common Stock specified in
paragraph 4, and (ii) subject to the prior rights of the holders of Preferred
Stock, the holders of the shares of Class A Common Stock and Common Stock,
according to the number of shares of Class A Common Stock and Common Stock then
outstanding, shall be entitled to share ratably in all assets of the Corporation
available for distribution to its stockholders; provided, however, (x) that in
the event that the amount available for distribution to the holders of Class A
Common Stock is insufficient to permit the holders of Class A Common Stock to be
paid an amount equal to (1) the original per share purchase price paid to the
Corporation with respect to each such share of Class A Common Stock plus any
accrued but unpaid dividends, or, (2) with respect to those shares of Class A
Common Stock outstanding as a result of the conversion of shares of Series B
Preferred Stock, $2.00 per share

                                       14
<PAGE>

plus any accrued but unpaid dividends, or (3) with respect to those shares of
Class A Common Stock outstanding as a result of the conversion of shares of
Series C Preferred Stock, $3.50 per share plus any accrued and unpaid dividends
(such amounts being sometimes referred to as the "Class A Liquidation
Payments"), then the holders of Class A Common Stock shall be entitled before
any distribution or payment is made upon any Common Stock, to be paid an amount
equal to the Class A Liquidation Payments and (y) that if the assets to be
distributed among the holders of the Class A Common Stock shall be insufficient
to permit payment to such holders of the full amount of the Class A Liquidation
Payments, then the entire assets of the Corporation to be so distributed shall
be distributed ratably among the holders of Class A Common Stock. Upon any such
liquidation, dissolution or winding up of the Corporation in which the amount
available for distribution to the holders of Class A Common Stock is sufficient
to permit such holders to be paid the full amount of the Class A Liquidation
Payments (as described in clauses (x) and (y) above), after the holders of Class
A Common Stock shall have been paid in full the preferential amounts to which
they shall be entitled as provided herein, all remaining assets of the
Corporation which are available for distribution to its stockholders shall be
distributed ratably among the holders of Common Stock. Written notice of such
liquidation, dissolution or winding up, stating a payment date, the amount of
the Class A Liquidation Payments and the place where said Class A Liquidation
Payments shall be payable, shall be given by mail, postage prepaid, not less
than 30 days prior to the payment date stated therein, to the holders of record
of Class A Common Stock, such notice to be addressed to each such holder at his
post office address as shown by the records of the Corporation; provided,
however, that failure to give notice pursuant to this sentence shall not
invalidate the action involved. A Change of Control Event shall not, for
purposes of this paragraph 2, be deemed a liquidation, dissolution or winding up
of the Corporation.

      3. Conversion of Class A Common Stock.

      3A. Optional Conversion of Class A Common Stock. Subject to and upon
compliance with the provisions of this paragraph 3 and after receiving the
written consent of the holders of the majority of the outstanding shares of
Class A Common Stock ("Conversion Consent"), the holder of any share or shares
of Class A Common Stock shall have the right, at its option, to convert any such
shares of Class A Common Stock (except that upon any liquidation, dissolution or
winding up of the Corporation the right of conversion shall terminate at the
close of business on the last full business day next preceding the date fixed
for payment of the amount distributable on Class A Common Stock) into an equal
number of fully paid and non-assessable whole shares of Common Stock. Such
rights of conversion shall be exercised by the holder thereof by giving written
notice (which notice shall attach the Conversion Consent) that the holder elects
to convert a stated number of shares of Class A Common Stock into Common Stock
and by surrender of a certificate or certificates for the shares so to be
converted to the Corporation at its principal office (or such other office or
agency of the Corporation as the Corporation may designate by notice in writing
to the holder or holders of the Class A Common Stock) at any time during its
usual business hours on the date set forth in such notice, together with a
statement of the name or names (with address), subject to compliance with
applicable laws to the extent such designation shall involve a transfer, in
which the certificate or certificates for shares of Common Stock shall be
issued.

                                       15
<PAGE>

      3B. Automatic Conversion of Class A Common Stock. Notwithstanding anything
else herein to the contrary in this Section 3, in the event that, at any time
while any of the Class A Common Stock shall be outstanding, (i) the Corporation
shall complete a firm commitment underwritten public offering of Common Stock
registered under the Securities Act of 1933, as amended, in which (x) the
aggregate price paid for such shares by the public shall be at least $30,000,000
and (y) the price per share paid by the public for such shares shall be at least
$6 per share (appropriately adjusted to reflect stock splits and combinations
and stock dividends) (a "Qualified Offering") or (ii) a majority of the issued
shares of Class A Common Stock shall have been converted into Common Stock, then
all outstanding shares of Class A Common Stock shall be automatically and
without further action on the part of the holders of the Class A Common Stock
converted into shares of Common Stock in accordance with the terms of subsection
3A hereof with the same effect as if the certificates evidencing such shares had
been surrendered for conversion, such conversion to be effective immediately
prior to the closing of such Qualified Offering or immediately prior to the
conversion of Class A Common Stock satisfying clause (ii) above, as the case may
be; provided, however, that certificates evidencing the shares of Common Stock
issuable upon such conversion shall not be issued except on surrender of the
certificates for the shares of the Class A Common Stock so converted.

      3C. Issuance of Certificates: Time Conversion Effected. Promptly after the
receipt by the Corporation of the written notice referred to in subparagraph 3A
and surrender of the certificate or certificates for the share or shares of the
Class A Common Stock to be converted, the Corporation shall issue and deliver,
or cause to be issued and delivered, to the holder, registered in such name or
names as such holder may direct, subject to compliance with applicable laws to
the extent such designation shall involve a transfer, a certificate or
certificates for the number of whole shares of Common Stock issuable upon the
conversion of such share or shares of Class A Common Stock. To the extent
permitted by law, such conversion shall be deemed to have been effected
immediately prior to the close of business on the day the certificate or
certificates for such share or shares shall have been surrendered as aforesaid,
and at such time the rights of the holder of such share or shares of Class A
Common Stock shall cease, and the person or persons in whose name or names any
certificate or certificates for shares of Common Stock shall be issuable upon
such conversion shall be deemed to have become the holder or holders of record
of the shares represented thereby.

      3D. Fractional Shares: Dividends: Partial Conversion. No fractional shares
shall be issued upon conversion of the Class A Common Stock into Common Stock,
nor shall any payment or adjustment be made upon any conversion on account of
any cash dividends on the Class A Common Stock so converted or the Common Stock
issued upon such conversion. In case the number of shares of Class A Common
Stock represented by the certificate or certificates surrendered pursuant to
subparagraph 3A exceeds the number of shares converted, the Corporation shall,
upon such conversion, execute and deliver to the holder thereof, at the expense
of the Corporation, a new certificate or certificates for the number of shares
of Class A Common Stock, represented by the certificate or certificates
surrendered which are not to be converted. If any fractional interest in a share
of Common Stock would, except for the provisions of the first sentence of this
subparagraph 3D, be deliverable upon any such conversion, the Corporation, in
lieu of delivering the fractional share thereof, shall pay to the holder
surrendering the Class A Common Stock for conversion an amount in cash equal to
the current fair value of such fractional interest as determined in good faith
by the Board of Directors of the Corporation.

                                       16
<PAGE>

      3E. Subdivision or Combination of Stock. In case the Corporation shall at
any time subdivide its outstanding shares of Common Stock into a greater number
of shares or shall declare or pay a dividend on its outstanding shares of Common
Stock payable in shares of Common Stock, then in each case the Class A Common
Stock shall be similarly subdivided, and conversely, in case the outstanding
shares of Common Stock of the Corporation shall be combined into a smaller
number of shares, the Class A Common Stock shall be similarly combined.

      3F. Reorganization. Reclassification, Merger or Sale. If any capital
reorganization or reclassification of the capital stock of the Corporation shall
be effected in such a way (including, without limitation, by way of
consolidation or merger) that holders of Common Stock shall be entitled to
receive stock, securities or assets with respect to or in exchange for Common
Stock, then, as a condition of such reorganization or reclassification, lawful
and adequate provision (in form satisfactory to the holders of at least a
majority of the outstanding shares of Class A Common Stock) shall be made
whereby each holder of a share or shares of Class A Common Stock shall
thereafter have the right to receive, upon the basis and upon the terms and
conditions specified herein and in lieu of the shares of Common Stock of the
Corporation immediately theretofore receivable upon the conversion of such share
or shares of Class A Common Stock, such shares of stock, securities or assets as
may be issued or payable with respect to or in exchange for a number of
outstanding shares of such Common Stock equal to the number of shares of such
stock immediately theretofore so receivable had such reorganization or
reclassification not taken place, and in any such case appropriate provision
shall be made with respect to the rights and interests of such holder to the end
that the provisions hereof shall thereafter be applicable, as nearly as maybe,
in relation to any shares of stock, securities or assets thereafter deliverable
upon the exercise of such conversion rights. In the event of a merger or
consolidation of the Corporation as a result of which a greater or lesser number
of shares of common stock of the surviving corporation are issuable to holders
of Common Stock of the Corporation outstanding immediately prior to such merger
or consolidation, the number of shares of Common Stock into which Class A Common
Stock may be converted shall be adjusted in the same manner as though there were
a subdivision or combination of the outstanding shares of Common Stock of the
Corporation. The Corporation will not effect any such consolidation or merger,
or any sale of all or substantially all its assets and properties, unless prior
to the consummation thereof the successor corporation (if other than the
Corporation) resulting from such consolidation or merger or the corporation
purchasing such assets shall assume by written instrument (in form reasonably
satisfactory to the holders of at least a majority of the shares of Class A
Common Stock at the time outstanding) executed and mailed or delivered to each
holder of shares of Class A Common Stock at the last address of such holder
appearing on the books of the Corporation, the obligation to deliver to such
holder such shares of stock, securities or assets as, in accordance with the
foregoing provisions, such holder may be entitled to receive,

      3G. Notice of Adjustment. Upon any adjustment made pursuant to 3E or 3F,
then and in each such case the Corporation shall give written notice thereof, by
first class mail, postage prepaid, addressed to each holder of shares of Class A
Common Stock at the address of such holder as shown on the books of the
Corporation, which notice shall state the number of shares of Common Stock or
other securities, cash or property issuable upon conversion of the Class A
Common Stock resulting from such adjustment, setting forth in reasonable detail
the method of calculation and the facts upon which such calculation is based.

                                       17
<PAGE>

      3H. Stock to be Reserved. The Corporation will at all times reserve and
keep available out of its authorized but unissued Common Stock, solely for the
purpose of issuance upon the conversion of the Class A Common Stock as herein
provided, such number of shares of Common Stock as shall then be issuable upon
the conversion of all outstanding shares of Class A Common Stock. All shares of
Common Stock which shall be so issued shall be duly and validly issued and fully
paid and non-assessable and free from all taxes, liens and charges arising out
of or by reason of the issue thereof, The Corporation will take all such action
within its control as may be necessary on its part to assure that all such
shares of Common Stock may be so issued without violation of any applicable law
or regulation, or of any requirements of any national securities exchange upon
which the Common Stock of the Corporation may be listed.

      3I. No Reissuance of Class A Common Stock. Shares of Class A Common Stock
which are converted into shares of Common Stock as provided herein shall not be
reissued,

      3J. Issue Tax. The issuance of certificates for shares of Common Stock
upon conversion of the Class A Common Stock shall be made without charge to the
holders thereof for any issuance tax in respect thereof, provided that the
Corporation shall not be required to pay any tax which may be payable in respect
of any transfer involved in the issuance and delivery of any certificate in a
name other than that of the holder of the Class A Common Stock which is being
converted.

      3K. Closing of Books. The Corporation will at no time close its transfer
books against the transfer of any Class A Common Stock or of any shares of
Common Stock issued or issuable upon the conversion of any shares of Class A
Common Stock in any manner which interferes with the timely conversion of such
Class A Common Stock,

      3L. Definition of Common Stock. As used in this paragraph 3, the term
"Common Stock" shall mean and include the Corporation's authorized Common Stock,
$.01 par value, as constituted on June 1, 2000 and shall also include any
capital stock of any class of the Corporation thereafter authorized which shall
not be limited to a fixed sum or percentage of par value in respect of the
rights of the holders thereof to participate in dividends or in the distribution
of assets upon the voluntary or involuntary liquidation, dissolution or winding
up of the Corporation; provided that the shares of Common Stock receivable upon
conversion of shares of the Class A Common Stock, or in case of any
reorganization or reclassification of the outstanding shares thereof, the stock,
securities or assets provided for in subparagraphs 3E or 3F, shall include only
shares designated as Common Stock of the Corporation on June 1, 2000.

      4. Conversion of Class B Common Stock.

      4A. Optional Conversion of Class B Common Stock. Subject to and upon
compliance with the provisions of this paragraph 4 and at any time prior to the
occurrence of a Triggering Event (as defined below), the holder of the
outstanding shares of Class B Common Stock shall have the right, at its option,
to convert all such shares of Class B Common Stock into shares of the common
capital stock ("USPE Shares") of United Surgical Partners Europe, S .L., a
company organized under the laws of Spain ("USPE"), in accordance with the
formula set forth in subsection 4D hereof. The conversion right granted by this
subsection 4A shall be on a one-time, all or none basis with respect to all of
the outstanding shares of Class B Common Stock. Such

                                       18
<PAGE>

right of conversion shall be exercised by the holder thereof by giving written
notice that the holder elects to convert all of the shares of Class B Common
Stock into USPE Shares and by surrender of a certificate or certificates for the
shares so to be converted to the Corporation at its principal office (or such
other office or agency of the Corporation as the Corporation may designate by
notice in writing to the holder of the Class B Common Stock) at any time during
its usual business hours, together with a statement of the name or names (with
address), subject to compliance with applicable laws to the extent such
designation shall involve a transfer, in which the USPE Shares shall be issued,
To the extent permitted by law, such conversion shall be deemed to have been
effected immediately prior to the close of business on the day the certificate
or certificates for such shares shall have been surrendered as aforesaid, and at
such time the rights of the holder of such shares of Class B Common Stock shall
cease, and the person or persons in whose name or names any certificate or
certificates for USPE Shares shall be issuable upon such conversion shall be
deemed to have become the holder or holders of record of the shares represented
thereby. Notwithstanding the provisions of the preceding sentence, the holder of
shares of Class B Common Stock shall have the right to deliver written notice of
conversion which provides (i) that the conversion of the Class B Common Stock
into USPE Shares is conditioned upon the occurrence of a specified USPE
Triggering Event, and (ii) that such holder may rescind the conversion notice by
delivering written notice of such rescission to the Corporation in the manner
provided above prior to the conversion of the Class B Common Stock; if the
holder of the Class B Common Stock delivers a conditional notice as provided
herein, the conversion of the Class B Common Stock shall be effective
immediately prior to the applicable USPE Triggering Event (unless rescinded as
provided above).

      4B. Automatic Conversion of Class B Common Stock. Upon the occurrence of a
Triggering Event at the Corporation or USPE, all outstanding shares of Class B
Common Stock shall be automatically and without further action on the part of
the holders of the Class B Common Stock converted into shares of Common Stock in
accordance with the terms of subsection 4C hereof, such conversion to be
effective immediately prior to the Triggering Event; provided, however, that
certificates evidencing the shares of Common Stock issuable upon such conversion
shall not be issued except on surrender of the certificates for the shares of
the Class B Common Stock so converted. The Corporation shall provide the holders
of the shares of Class B Common Stock at least 30 days (or such shorter period
as may be acceptable to the holders) prior written notice of the proposed
Triggering Event. Such notice will be sent by first class mail, postage prepaid,
addressed to each holder of shares of Class B Common Stock at the address of
such holder as shown on the books of the Corporation and the Corporation shall
also concurrently provide notice to such holders by e-mail or facsimile
transmission; provided, however, that failure to give notice pursuant to this
sentence shall not invalidate the underlying Triggering Event, Notwithstanding
the foregoing, in addition to any other remedies available under applicable law,
if the Corporation fails to give notice of a Triggering Event pursuant to the
provisions of this Section 4B, the holders of the Class B Common Stock
(immediately prior to the occurrence of such Triggering Event) shall have the
right to cause the Corporation to convert such holders Common Stock issued upon
conversion of such Class B Common Stock into USPE Shares or, if as of such time
a USPE Triggering Event shall have occurred, to exchange such Common Stock into
the consideration that such holder would have received in connection with the
USPE Triggering Event had such holder exercised its conversion rights under
Section 4A prior to such USPE Triggering Event; the right set forth in this
sentence shall expire thirty days

                                       19
<PAGE>

after the Corporation shall have delivered notice of the applicable Triggering
Event to such holder.

      4C. USPI Conversion Ratio. Each share of Class B Common Stock shall, upon
the occurrence of a Triggering Event, be converted into that number of fully
paid and non-assessable whole shares of Common Stock which results from the
product of one times the USPI Conversion Ratio, The USPI Conversion Ratio is:

      (QI x .07) + (HMTIS x ERI/ERL) + ~HMTCO)
      ----------------------------------------
      (HMTIS x ERI/ERL) + (HMTCO)

      Where,

      QI = the number of shares issued in a Qualified Investment (as defined in
the Stockholders Agreement)

      ERI = 160 Spanish pesetas (or, if as of the applicable time, the Spanish
peseta is no longer in use, then equivalent amount as of the applicable date in
Euros)

      ERL = the Exchange Rate, in Spanish pesetas per dollar, on the date of the
Triggering Event (or, if as of the applicable time, the Spanish peseta is no
longer in use, then equivalent amount as of the applicable date in Euros)

      HMTIS = the number of shares of Class B Common Stock outstanding on the
date hereof (1,000,000)

      HMTCO = the number of shares of Class B Common Stock issued in HMT
Co-Investments (as defined in the Stockholders Agreement)

      For purposes of this ratio, notwithstanding the fact that QI represents
shares of capital stock of USPE and not USPI, QI, HMTIS and HMTCO shall be
appropriately adjusted to reflect stock splits and combinations and stock
dividends of the Class B Common Stock or the Common Stock but not the USPE
Shares)

      4D. USPE Conversion Formula. All of the outstanding shares of Class B
Common Stock shall, upon the exercise of the conversion right granted by
subsection 4A hereof, be converted into that number of fully paid and
non-assessable whole USPE Shares which results in a percentage ownership in USPE
equal to that obtained by applying the following formula:

      (BV x .12) + (QI x .07) + MCOINV
      --------------------------------
                    BV+QI

      Where,

      BV = the Corporation's equity investment in USPE on the date hereof
($29,752,664)

                                       20
<PAGE>

      QI = the Corporation's additional equity investments in USPE after the
date hereof, in dollars (measured as of the date of each such investment based
upon the Exchange Rate in effect on each such date)

      MCOINV = the dollar value of shares of Class B Common Stock issued
pursuant to HMT Co-Investments (as defined in the Stockholders Agreement)
(measured as of the date of each such investment based upon the Exchange Rate in
effect on each such date)

      4E. Stock to be Reserved. USPE and the Corporation, as applicable, will at
all times reserve and keep available out of the authorized but unissued USPE
Shares or Common Stock, as applicable, solely for the purpose of issuance upon
conversion in accordance with subsection 4A or 4B, as applicable, such number of
USPE Shares or shares of Common Stock, as applicable, as shall then be issuable
upon the conversion of all outstanding shares of Class B Common Stock, With
respect to USPE Shares issuable upon conversion of the Class B Common Stock,
USPI undertakes to transfer the applicable number of USPI's USPE Shares to the
holder of such converted Class B Common Stock or, alternatively, to pass a
shareholders' resolution at USPE in order to agree to a share capital increase
in USPE to provide the applicable number of USPE Shares which shall be
subscribed by the holder of the converted Class B Common Stock by means of a
contribution in kind of such holder's converted Class B Common Stock. USPE and
the Corporation, as applicable, shall take all such action within their control
as may be necessary on their part to assure that all such shares may be so
issued without violation of any applicable law or regulation, or of any
requirements of any securities exchange upon which such shares may be listed.

      4F. Issuance of Certificates: No Fractional Shares. Promptly after the
receipt by the Corporation of the written notice referred to in subsection 4A or
the Triggering Event giving rise to a conversion under subsection 4B and
surrender by the holder of the certificate or certificates representing the
holder's shares of Class B Common Stock, USPE or the Corporation, as
appropriate, shall issue and deliver, or cause to be issued and delivered, to
the holder, registered in such name or names as such holder may direct, subject
to applicable law to the extent such designation shall involve a transfer, a
certificate or certificates for the number of whole USPE Shares or shares of
Common Stock, as applicable, issuable upon the conversion of the holder's Class
B Common Stock. If any fractional interest in a USPE Share or share of Common
Stock would, except for the provisions of this subsection, be deliverable upon
conversion, the Corporation, in lieu of delivery by USPE or the Corporation, as
appropriate, of the fractional share thereof, shall pay to the holder upon
surrender of the certificates representing the holder's Class B Common Stock for
conversion an amount in cash equal to the current fair market value of such
fractional interest as determined in good faith by the Board of Directors of the
Corporation.

      4G. Subdivision or Combination of Stock. In case the Corporation shall at
any time subdivide its outstanding shares of Common Stock into a greater number
of shares or shall declare or pay a dividend on its outstanding shares of Common
Stock payable in shares of Common Stock, then in each case the Class B Common
Stock shall be similarly subdivided, and conversely, in case the outstanding
shares of Common Stock of the Corporation shall be combined into a smaller
number of shares, the Class B Common Stock shall be similarly combined.

                                       21
<PAGE>

      4H. Reorganization. Reclassification, Merger or Sale. If any capital
reorganization or reclassification of the capital stock of the Corporation shall
be effected in such a way (including, without limitation, by way of
consolidation or merger) that holders of Common Stock shall be entitled to
receive stock, securities or assets with respect to or in exchange for Common
Stock, then, as a condition of such reorganization or reclassification, lawful
and adequate provision (in form satisfactory to the holders of at least a
majority of the outstanding shares of Class B Common Stock) shall be made
whereby each holder of a share or shares of Class B Common Stock shall
thereafter have the right to receive, upon the basis and upon the terms and
conditions specified herein and in lieu of the shares of Common Stock of the
Corporation immediately theretofore receivable upon the conversion of such share
or shares of Class B Common Stock, such shares of stock, securities or assets as
may be issued or payable with respect to or in exchange for a number of
outstanding shares of such Common Stock equal to the number of shares of such
stock immediately theretofore so receivable had such reorganization or
reclassification not taken place, and in any such case appropriate provision
shall be made with respect to the rights and interests of such holder to the end
that the provisions hereof shall thereafter be applicable, as nearly as may be,
in relation to any shares of stock, securities or assets thereafter deliverable
upon the exercise of such conversion rights. In the event of a merger or
consolidation of the Corporation as a result of which a greater or lesser number
of shares of common stock of the surviving corporation are issuable to holders
of Common Stock of the Corporation outstanding immediately prior to such merger
or consolidation, the number of shares of Common Stock into which the Class B
Common Stock may be converted shall be adjusted in the same manner as though
there were a subdivision or combination of the outstanding shares of Common
Stock of the Corporation. The Corporation will not effect any such consolidation
or merger, or any sale of all or substantially all its assets and properties,
unless prior to the consummation thereof the successor corporation (if other
than the Corporation) resulting from such consolidation or merger or the
corporation purchasing such assets shall assume by written instrument (in form
reasonably satisfactory to the holders of at least a majority of the outstanding
shares of Class B Common Stock at the time outstanding) executed and mailed or
delivered to each holder of shares of Class B Common Stock at the last address
of such holder appearing on the books of the Corporation, the obligation to
deliver to such holder such shares of stock, securities or assets as, in
accordance with the foregoing provisions, such holder may be entitled to
receive.

      4I. Notice of Adjustment. Upon any adjustment made pursuant to 4G or 4H,
then and in each such case the Corporation shall give written notice thereof, by
first class mail, postage prepaid, addressed to each holder of shares of Class B
Common Stock at the address of such holder as shown on the books of the
Corporation, which notice shall state the number of USPE Shares or shares of
Common Stock or other securities, cash or property issuable upon conversion of
the Class B Common Stock resulting from such adjustment, setting forth in
reasonable detail the method of calculation and the facts upon which such
calculation is based.

      4J. Cancellation of Class B Common Stock upon Conversion. Upon any
conversion under subsection 4A or 4B, the holder's Class B Common Stock shall be
canceled and shall cease to be outstanding.

      4K. Issue Tax. The issuance of certificates for USPE Shares or shares of
Common Stock upon conversion of the Class B Common Stock shall be made without
charge to the

                                       22
<PAGE>

holders thereof for any issuance tax in respect thereof, provided that the
Corporation shall not be required to pay any tax which may be payable in respect
of any transfer involved in the issuance and delivery of any certificate in a
name other than that of the holder of the Class B Common Stock which is being
converted.

      4L. Definition of Triggering Event. As used in this paragraph 4, the term
"Triggering Event" at the Corporation or USPE means any of the following: (i) a
consolidation or merger of the Corporation or USPE, as applicable, with or into
any other entity (other than a merger which will not result in more than 50% of
the voting capital stock of the Corporation or USPE, as applicable, outstanding
immediately after the effective date of such merger being owned of record or
beneficially by persons other than the holders of such voting capital stock
immediately prior to such merger in the same proportions in which such shares
were held immediately prior to such merger), (ii) a sale of all or substantially
all of the properties and assets of the Corporation or USPE, as applicable, as
an entirety in a single transaction or in a series of transactions to any other
person or persons, (iii) the acquisition of "beneficial ownership" by any
"person" or "group" (other than Welsh, Carson, Anderson & Stowe VII, L.P. or its
affiliates) of voting stock of the Corporation or USPE, as applicable,
representing more than 50% of the voting power of all outstanding shares of such
voting stock, whether by way of merger, consolidation or otherwise, (iv) the
completion by the Corporation or USPE, as applicable, of a firm commitment
underwritten public offering of Common Stock or USPE Shares, as applicable,
registered under applicable securities laws, in which (x) the aggregate price
paid for such shares by the public is at least $30,000,000, or (y) the price per
share paid by the public shall be at least $6 per share (appropriately adjusted
to reflect stock splits and combinations and stock dividends), (v) a sale by the
Corporation, to one or more persons other than affiliates of the Corporation, of

                                    GUARANTY

      For good and valuable consideration, the receipt and sufficiency of which
is hereby acknowledged, and to induce United Surgical Partners International,
Inc., a company incorporated in the State of Delaware (herein, with its
successors and assigns, called the "Lender"), at any time or from time to time,
to make loans or extend other accommodations to or for the account of Health
Dream Team, S.C., a company incorporated in Spain (herein called "Borrower'"),
the undersigned (the "Guarantor"), an individual residing in Spain, and a
shareholder of Borrower, hereby absolutely and unconditionally guarantees to
Lender the full and prompt payment when due, whether at maturity or earlier by
reason of acceleration or otherwise, of the debts, accounts, and obligations
herein described.

      WHEREAS, the Lender has agreed to advance sums or extend credit to or for
of the Borrower pursuant to the terms of Section 3.2 of a Stockholders Agreement
dated September 26, 2000, by and among Borrower, Lender and United Surgical
Partners Europe, S.L., a company incorporated in Spain (the "Stockholders
Agreement");

      WHEREAS, Borrower is indebted to Lender pursuant to a promissory note
dated September 26, 2000, issued pursuant to the Stockholders Agreement in the
original principal amount of $811,093.00 (the "Note");

      WHEREAS, as security for repayment of the amounts due any additional
promissory notes issued pursuant to Section 3.2 of the Stockholders Agreement
(together, the "Notes"), Borrower has pledged certain assets to the Lender as
described in a Stock Pledge Agreement dated September 26, 2000 ("Collateral");
and

      WHEREAS, in order to induce Lender to extend to Borrower the loan or loans
evidenced by the Notes, Borrower has agreed to procure and deliver, and the
Guarantor has agreed to give this Guaranty, and Lender has refused to extend
said loan or loans to Borrower unless this Guaranty is executed by the Guarantor
and delivered to Lender.

      NOW, THEREFORE, in consideration of these premises, the Guarantor hereby
covenants and agrees with Lender as follows:

Section 1. Guaranty.

                                       5
<PAGE>

      The Guarantor guarantees to Lender the payment and performance of the
debts, liabilities and obligations of Borrower to Lender evidenced by or arising
out of the Notes, and any extensions, renewals or replacements thereof and
including also all amounts paid to the Lender by the Borrower that are recovered
from Lender in any legal proceeding (herein referred to as the "Indebtedness");
provided, however, notwithstanding the foregoing, the liability of the
undersigned shall not exceed the Applicable Pro Rata Portion of the principal
sum of the Indebtedness at any one time outstanding, together with accrued but
unpaid interest thereon, and costs of collection including reasonable attorneys
fees. "Applicable Pro Rata Portion" means the principal sum of the Indebtedness
at any one time outstanding, together with accrued but unpaid interest thereon,
and costs of collection including reasonable attorneys fees times the percentage
of Borrower's capital shares held by Guarantor.

Section 2. No Contingencies.

      No act or thing need occur to establish the liability of the Guarantor
hereunder, and no act or thing, except full payment and discharge of the
Indebtedness or the payment by the Guarantor of his Applicable Pro Rata Portion
of the Indebtedness, shall in any way exonerate the Guarantor or modify, reduce,
limit or release the liability of the Guarantor hereunder.

Section 3 Continuing Guaranty; Revocation.

      This is an absolute, unconditional and continuing guarantee of payment of
the Indebtedness and shall continue to be in force and be binding upon the
Guarantor, whether or not the Indebtedness is paid in full. The death or
incompetence of the Guarantor shall not revoke this Guaranty as to the
Indebtedness or any part thereof.

Section 4. Intentionally Omitted.

Section 5. Other Collateral.

      The Guarantor hereby agrees that Lender may take other guarantees,
collateral or security to further secure the Indebtedness, and any terms,
covenants and conditions contained in any note or agreement evidencing or
relating to the Indebtedness may be altered, extended, changed, modified, or
released without in any manner affecting this Guaranty or releasing the
Guarantor. The Guarantor shall remain liable to pay Guarantor's Applicable Pro
Rata Portion of the Indebtedness as so altered, extended, changed or modified,
notwithstanding the taking of such other guarantees, collateral or security.

Section 6. Subordination.

      The Guarantor will not exercise or enforce any right of contribution,
reimbursement, recourse or subrogation available to the Guarantor against any
person liable for payment of the Indebtedness, or as to any collateral security
therefor, unless and until all the Indebtedness shall have been fully paid and
discharged. Any such right of contribution, reimbursement, recourse or
subrogation available to the Guarantor is expressly made subordinate to the
lien, time of payment

                                       6
<PAGE>

and in all other respects to the amounts owing to Lender under this Guaranty and
on the Indebtedness.

Section 7. Costs Expenses and Attorneys' Fees.

      The Guarantor will pay or reimburse Lender for all costs and expenses
(including reasonable attorneys' fees and legal expenses) actually incurred by
Lender in connection with the protection, defense or enforcement of this
Guaranty.

Section 8. Consent to Certain Actions.

      Whether or not any existing relationship between the Guarantor and
Borrower has been changed or ended and whether or not this Guaranty has been
revoked, Lender may, but shall not be obligated to, enter into transactions
resulting in the creation or continuance of the Indebtedness, without any
consent or approval by the undersigned and without any notice to the Guarantor.
The liability of the Guarantor shall not be affected or impaired by any of the
following acts or things (which Lender is expressly authorized to do, omit or
suffer from time to time, both before and after revocation of this Guaranty,
without notice to or approval by the Guarantor): (i) any acceptance of
collateral security, guarantors, accommodation parties or sureties for any or
all of the Indebtedness; (ii) any one or more extensions or renewals of the
Indebtedness (whether or not for longer than the original period) or any
modification of the interest rates, maturities or other contractual term
applicable to any of the Indebtedness; (iii) any waiver or indulgence granted to
Borrower, any delay or lack of diligence in the enforcement of the Indebtedness,
or any failure to institute proceedings, file a claim, give any required notices
or otherwise protect any of the Indebtedness; (iv) any full or partial release
of, settlement with, or agreement not to sue Borrower or any other guarantor or
other person liable in respect to any of the Indebtedness; (v) any discharge of
any evidence of the Indebtedness or other acceptance of any instrument in
renewal thereof or substitution therefor; (vi) any failure to obtain collateral
security (including rights of setoff) for the Indebtedness, or to see to the
proper or sufficient creation and perfection thereof, or to establish the
priority thereof, or to protect, insure or enforce any collateral security; or
any modification, substitution, discharge, impairment, or loss of any collateral
security; (vii) any foreclosure or enforcement of any collateral security;
(viii) any transfer of any of the Indebtedness or any evidence thereof; (ix) any
order of application of any payments or credits upon the Indebtedness; or (x)
any election by the Lender under Sec. 1111(b)(2) of the United States Bankruptcy
Code.

Section 9. Waiver of Defenses: Deficiency.

      The Guarantor waives any and all defenses, claims and discharges of
Borrower, or any other obligor, pertaining to the Indebtedness, except the
defense of discharge by payment in full. Without limiting the generality of the
foregoing, the Guarantor will not assert, plead or enforce against Lender any
defense of waiver, release, discharge in bankruptcy, statute of limitations, res
judicata, statute of frauds, antideficiency statute, fraud, incapacity,
minority, usury, illegality or unenforceability which may be available to
Borrower or any other person liable in respect to any of the Indebtedness, or
any setoff available against Lender to Borrower or any such other person,
whether or not on account of a related transaction.

<PAGE>

Section 10. Cumulative Remedies.

      The Guarantor waives presentment, demand for payment, notice of dishonor
or nonpayment, and protest of any instrument evidencing the Indebtedness,
notices of default and all other notices now or hereafter provided by law.
Lender shall not be required to resort first to Borrower for payment of the
Indebtedness or to other persons or their properties, nor to enforce, realize
upon or exhaust any collateral security for the Indebtedness, before enforcing
this Guaranty. All remedies afforded to Lender by reason of this Guaranty are
separate and cumulative, and no one of such remedies, whether exercised by
Lender or not, shall be deemed an exclusion of any other remedies available to
Lender, and shall in no way limit or prejudice any other legal or equitable
remedies Lender may have against Borrower or any Guarantor pursuant to the
Stockholders Agreement, the Notes or any other documents or instruments executed
or delivered in connection therewith. All payments made by Borrower and the
Guarantor or by any other person, and the proceeds of any security, may be
applied by Lender to the Indebtedness as Lender may determine, whether the same
be due or not. Any remedy or right hereby granted which shall be found to be
unenforceable as to any person or circumstance, for any reason, shall in no way
limit or prevent the enforcement of such remedy or right as to any other person
or circumstance, nor shall such unenforceability limit or prevent enforcement of
any other remedy or right hereby granted.

Section 11. Rescinded Payments.

      If any payment applied by Lender to the Indebtedness is thereafter set
aside, recovered, rescinded or required to be returned for any reason
(including, without limitation, the bankruptcy, insolvency or reorganization of
Borrower or any other obligor), the Indebtedness to which such payment was
applied shall, for the purposes of this Guaranty, be deemed to have continued in
existence, notwithstanding such application, and this Guaranty shall be
enforceable as to such Indebtedness as fully as if such application had never
been made.

      The liability of the Guarantor under this Guaranty is in addition to and
shall be cumulative with all other liabilities of the Guarantor to the Lender as
guarantor or otherwise, without any limitation as to amount, unless the
instrument or agreement evidencing or creating such other liability specifically
provides to the contrary. Execution of this Guaranty shall not act as a
revocation of any prior guarantee by the Guarantor of the Indebtedness of
Borrower.

Section 13. Liability Acceptance Enforceability, Waiver Governing, Law.

      This Guaranty shall be effective upon delivery to the Lender, without
further act, condition or acceptance by Lender and shall be binding upon the
Guarantor and heirs, representatives, successors and assigns of the Guarantor,

incorporated in Spain ("HDT"), and (ii) UNITED SURGICAL PARTNERS INTERNATIONAL,
INC., a company incorporated in the State of Delaware ("USPI").

      RECITALS:

      A. HDT is indebted to USPI pursuant to that certain Promissory Note (the
"Note") of even date herewith in the face amount of $811,093.00 made by HDT and
payable to the order of USPI.

      C. Pursuant to Section 3.2 of a Stockholders Agreement dated September 26,
2000 (the Stockholders Agreement"), by and among HDT, USPI and United Surgical
Partners Europe, S.L., a company organized under the laws of Spain ("USPE"), HDT
may become further indebted to USPI, as evidenced by additional promissory notes
(such additional promissory notes, together with the Note, the "Notes").

      B. In order to induce USPI to make the loans to HDT evidenced by the
Notes, HDT has agreed to pledge 1,000,000 shares of Class B Common Stock of USPI
(the "Stock") to USPI, to assure repayment of the Notes by HDT.

      AGREEMENT:

      Now, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereto hereby covenant,
agree, represent and warrant as follows:

      1. PLEDGE AND DEPOSIT OF SHARES. HDT hereby pledges and assigns to USPI,
and grants to USPI a security interest in, the Stock, as represented by
certificate number CB-001 now standing in HDT's name, which certificate has been
delivered by HDT to USPI contemporaneously herewith, together with a duly
executed blank stock power attached thereto, all as collateral security for all
amounts which HDT may owe USPI pursuant to the Notes.

      The certificates or other instruments evidencing all new shares of capital
stock and all other securities, rights, warrants, options and the like hereafter
created in respect of the Stock, whether by stock split, stock dividend, merger,
consolidation or otherwise, shall be delivered by HDT to, and shall be held by,
USPI under the terms and conditions of this Agreement and subject to the pledge
and security interest herein granted, and the term "Stock" as used herein shall
be deemed to include all such new shares, securities, rights, warrants, options
and the like.

      2. VOTING RIGHTS. So long as no "Event of Default" as hereinafter defined,
shall have occurred and be continuing, HDT shall be entitled to exercise any and
all voting

<PAGE>

and/or consensual rights and powers relating or pertaining to the Stock or any
part thereof for any purpose not inconsistent with the terms of this Agreement.

      Notwithstanding anything to the contrary contained in this Section 2, upon
the occurrence of any Event of Default, USPI shall be entitled to exercise all
voting rights and privileges whatsoever with respect to the Stock, and to that
end HDT hereby constitutes USPI as its proxy and attorney-in-fact for all
purposes of voting the Stock under such circumstances, and this appointment
shall be deemed coupled with an interest and is and shall be irrevocable until
the Notes have been fully paid. HDT shall execute and deliver to USPI any and
all additional proxies and powers of attorney that USPI may desire in order to
vote more effectively the Stock in its own name.

      3. STATUS OF STOCK. HDT hereby represents and warrants to USPI that (a)
all of the Stock is free and clear of all liens, charges and encumbrances, and
(b) HDT has the full power and authority to pledge the Stock to USPI pursuant to
this Agreement. No part of the Stock shall be sold, transferred or assigned by
HDT without the prior written consent of USPI, which consent may be arbitrarily
withheld so long as this Agreement is in effect.

      4. MAINTENANCE OF PRIORITY of PLEDGE. HDT shall be liable for and shall
from time to time pay and discharge all taxes, assessments and governmental
charges imposed upon the Stock by any federal, state, local or foreign
authority, the liens of which would or might be held prior to the right of USPI
in and to the Stock or which are imposed on the holders or registered owners of
the Stock. HDT shall not, at any time while this Agreement is in effect, do or
suffer any act or thing whereby the rights of USPI in the Stock would or might
be materially impaired or diminished. HDT shall execute and deliver such further
documents and take such further actions as may be required to confirm the rights
of USPI in and to the Stock or otherwise to effectuate the intention of this
Agreement.

      5. EVENTS of DEFAULT. Each of the following shall be deemed an "Event of
Default" hereunder:

      (a) The occurrence of any "Default" under the Notes not cured within the
applicable grace period;

      (b) The occurrence of any default of any kind whatsoever other than as
provided in subparagraph (a) above, under the terms, covenants and conditions of
this Agreement not cured within thirty (U) days following receipt by HDT of
written notice from USPI specifying such default; or

      (c) If any representation or warranty made by HDT in this Agreement, the
Stockholders Agreement, the Management Agreement or the Guaranty shall prove to
be untrue and misleading in any material respect.

      6. REMEDIES UPON DEFAULT. Upon the occurrence of any Event of Default
referred to in Section S above, USPI shall have all rights and remedies in and
against the Stock and otherwise of a secured party under the Uniform Commercial
Code as enacted in the State of Delaware (the "UCC") and all other applicable
domestic and foreign laws and shall also have all

foregoing, USPI shall have the right:

      (a) To sell the Stock in one or more lots, and from time to time, upon ten

upon credit or for future delivery. HDT hereby waives all rights, if any, of
marshaling the Stock for its obligations to USPI under this Agreement or
otherwise. USPI may, at its sole option, either:

      (1) sell the Stock at a public sale or sales, including a sale at or on
any broker's board or stock exchange; or

      (2) sell the Stock at a private sale or sales.

      (b) USPI may bid for and acquire the Stock or any portion thereof at any
public sale, free from any redemption rights of HDT, and in lieu of paying cash
therefor, may make settlement for the selling price of the Stock or any part
thereof by crediting the net selling price of the Stock against sums payable by
HDT after deducting all of USPI's costs and expenses of every kind and nature
therefrom, including USPI's attorneys' fees incurred in connection with
realizing upon the Stock, provided the same is not prohibited by the laws of the
State of Delaware.

      (c) From time to time USPI may, but shall not be obligated to, postpone
the time of any proposed sale of any of the Stock which has been the subject of
a notice as provided above, and also, upon ten (10) days' prior written notice
to HDT (which notice HDT conclusively agrees is commercially reasonable), may
change the time and/or place of such sale.

      7. FUTURE ADVANCES. This Agreement secures all additional loans and/or
future advances that may be made hereafter at any time by USPI to HDT pursuant
to Section 3.2 of the Stockholders Agreement. HDT agrees that upon additional
indebtedness being incurred by HDT under the terms of the Stockholders
Agreement, HDT will make any and all undertakings necessary or reasonably
required by USPI to modify or amend this Agreement to effectuate the pledge,
delivery and deposit of all future acquired Stock.
