         2.16    ACCOUNTS RECEIVABLE/PAYABLE.  The Balance Sheet reflects the
amount, as of the Balance Sheet Date and determined in conformity with
generally accepted accounting principles and the past practices employed by the
Company, of the Company's (i) accounts receivable, net of allowances for
uncollectible and doubtful amounts  ("Accounts Receivable") and (ii) current
accounts payable and current accrued liabilities (other than the current
portion of long-term debt) ("Accounts Payable").  Exhibit 2.16 contains a true
and accurate (i) list of all Accounts Receivable, (ii) list of all Accounts
Payable and (iii) statement of the working capital ("Working Capital") of the
Company as of the Balance Sheet Date.  The Company maintains its accounting
records in sufficient detail to substantiate the accounts receivable reflected
on the Balance Sheet and has given and will give to PRG Sub full and complete
access to those records, including the right to make copies therefrom.  Since
the Balance Sheet Date, the Company has not changed any





                                       7
<PAGE>   9
principle or practice with respect to the recordation of accounts receivable or
the calculation of reserves therefor, or any material collection, discount or
write-off policy or procedure.  Accounts Receivable are recorded in amounts
estimated to be net of contractual allowances related to third-party payor
arrangements.  The Company is in substantial compliance with the terms and
conditions of such third-party payor arrangements, and the reserves established
by the Company are adequate to cover any liability resulting from lack of
compliance.

         2.17    TAXES.  The Company has filed all tax returns required to be
filed by it, and made all payments of taxes, including any interest, penalty or
addition thereto, required to be made by it, with respect to income taxes, real
and personal property taxes, sales taxes, use taxes, employment taxes, excise
taxes and other taxes due and payable on or before the date of this Agreement.
All such tax returns are complete and accurate in all respects and properly
reflect the relevant taxes for the periods covered thereby.  The Company has no
tax liability, except for real and personal property taxes for the current
period not yet due and payable and sales, use, employment and similar taxes for
periods as to which such taxes have not yet become due and payable.   The
unpaid taxes of the Company did not, as of the Balance Sheet Date, exceed the
reserve for taxes (rather than any reserve for deferred taxes established to
reflect timing differences between book and income tax income) set forth on the
face of the Balance Sheet (rather than in any notes thereto), as adjusted for
the passage of time through the Closing Date (in accordance with the past
custom and practice of the Company).  The Company and the Shareholders have not
received any notice that any tax deficiency or delinquency has been asserted
against the Company.  There are no audits relating to taxes of the Company
threatened, pending or in process.  The Company is not currently the
beneficiary of any waiver of any statute of limitations in respect of taxes nor
of any extension of time within which to file any tax return or to pay any tax
assessment or deficiency.  There are no liens or encumbrances relating to taxes
on or threatened against any of the assets of the Company.  The Company has
withheld and paid all taxes required by law to have been withheld and paid by
it.  Neither the Company nor any predecessor of the Company is or has been a
party to any tax allocation or sharing agreement or a member of an affiliated
group of corporations filing a consolidated federal income tax return.  The
Company has delivered to PRG Sub correct and complete copies of the Company's
three most recently filed annual state and federal income tax returns, together
with all examination reports and statements of deficiencies assessed against or
agreed to by the Company during the three calendar year period preceding the
date of this Agreement.  The Company has neither made any payments, is
obligated to make any payments, or is a party to any agreement that under any
circumstance could obligate it to make any payments that will not be deductible
under Code section 280G.

         2.18    COMMISSIONS AND FEES.  There are no claims for brokerage
commissions or finder's or similar fees in connection with the transactions
contemplated by this Agreement which may be now or hereafter asserted against
PRG, PRG Sub, the Company or the Shareholders resulting from any action taken
by the Company or the Shareholders or their respective agents or employees, or
any of them.

         2.19    LIABILITIES; DEBT.  Except to the extent reflected or reserved
against on the Balance Sheet, the Company did not have, as of the Balance Sheet
Date, and has not incurred since that date and will not have occurred as of the
Closing Date, any liabilities or obligations of any nature, whether accrued,
absolute, contingent or otherwise, and whether due or to become due, other than

of a Straddle Period ending on the Closing Date and beginning after the Closing
Date shall be determined by apportioning the Tax for the entire Straddle Period
among such periods based on the number of days in each such period, provided
that, in the case of Taxes based upon or related to income or receipts, such
portion shall be the amount of Tax which would have been due if the relevant
Straddle Period ended on the Closing Date.  Any credits relating to a Straddle
Period shall be taken into account as though the relevant Straddle Period ended
on the Closing Date.  All determinations necessary to give effect to the
foregoing allocations shall be made in a manner consistent with prior practices
of the Company.

                 (c)      The Company, Shareholders, PRG, Surviving Corporation
and PRG Sub shall reasonably cooperate with each other in connection with the
filing of Tax Returns pursuant to this Section 11.5(c) and any audit,
litigation or other proceeding with respect to Taxes.  Such cooperation shall
include the provision of copies, at the requesting party's expense, of records
and information relevant to any such Tax Return or proceeding and making
employees available on a mutually convenient basis to provide additional
information and explanation of any material provided hereunder.

SECTION 12.      TERMINATION.  This Agreement may be terminated:

         (a)     at any time by mutual agreement of all parties;

         (b)     at any time by PRG or PRG Sub if any representation or
warranty of the Company or any Shareholder contained in this Agreement or in
any certificate or other document executed and delivered by the Company or any
Shareholder pursuant to this Agreement is or becomes untrue or breached in any
material respect or if the Company or any Shareholders fails to comply in any
material respect with any covenant or agreement contained herein, and any such
misrepresentation, noncompliance or breach is not cured, waived or eliminated
within twenty (20) days after receipt of written notice thereof;

         (c)     at any time by the Company or the Shareholders if any
representation or warranty of PRG or PRG Sub contained in this Agreement or in
any certificate or other document executed and delivered by PRG or PRG Sub
pursuant to this Agreement is or becomes untrue or breached in any material
respect or if PRG or PRG Sub fails to comply in any material respect with any
covenant or agreement contained herein and such misrepresentation,
noncompliance or bread is not cured, waived or eliminated within twenty (20)
days after receipt of written notice thereof;

         (d)     by PRG, PRG Sub, the Company or the Shareholders if the merger
contemplated hereby shall not have been consummated by June 28, 1996;

         (e)     by PRG at any time prior to the Closing Date if PRG determines
in its sole discretion as the result of its legal, financial and operational
due diligence with respect to the Company, that such termination is desirable
and in the best interests of PRG; or

         (f)     by the Shareholders if counsel for the Shareholders shall
determine, in its reasonable good faith judgment, that the provisions of
Section 11.3(III) shall not be satisfactory to protect the Shareholders with
respect to the claims discussed therein.


SECTION 13.      NONCOMPETITION.

         13.1    PROHIBITED ACTIVITIES.  In order to protect PRG, PRG Sub, the
Surviving Corporation and each of their affiliates (collectively, the "PRG
Group") against the unauthorized use or disclosure of any of their confidential
information presently known or hereinafter acquired by the Shareholders and
other good and valuable consideration, each Shareholder hereby agrees that,
subject to adjustment pursuant to Section 13.5, for a period of five (5) years
following the Closing Date, each Shareholder and his or her respective
affiliates shall not knowingly, directly or indirectly, for herself or himself
or on or behalf of any other corporation, person, firm, partnership,
association or any other entity (whether as an individual, agent, employee,
offer director or in any other capacity):

                 (a)      establish, operate or provide physician services at
any medical office, clinic or out-patient and/or ambulatory treatment or
diagnostic facility providing services similar to those provided by the Company
or engage or participate in or finance any business which engages in direct
competition with the business being conducted





                                       23
<PAGE>   25
by PRG, PRG Sub, Surviving Corporation or any practice managed by PRG or any
subsidiary of PRG anywhere within 50 miles of any location of PRG, PRG Sub,
Surviving Corporation or any practice managed by PRG or any subsidiary of PRG;
provided, however, that this provision shall not prohibit each Shareholder or
any of his or her affiliates from purchasing or holding an aggregate equity
interest of up to 2%, so long as such Shareholder and his or her affiliates
combined do not purchase or hold an aggregate equity interest of more than 5%,
in any business in direct competition with the PRG, PRG Sub, Surviving
Corporation or any practice managed by PRG or any subsidiary of PRG; or

                 (b)      induce or attempt to influence any employee of PRG,
PRG Sub, Surviving Corporation or any practice managed by PRG or any subsidiary
of PRG to terminate his or her employment, or to hire any such employee,
whether or not so induced or influenced, except that any such employee may be
hired with PRG's prior written consent.

         13.2    DAMAGES.

                 (a)      Because of the difficulty of measuring economic
losses to PRG, Surviving Corporation and PRG Sub as a result of the breach of
the foregoing covenant, and because of the immediate and irreparable damage
that would be caused to PRG, Surviving Corporation and PRG Sub for which it
would have no other adequate remedy, the Shareholders agree that, in the event
of a breach by them of the foregoing covenant, the covenant may be enforced by
PRG, Surviving Corporation or PRG Sub by injunctions and restraining orders.
The foregoing right is in addition to the right to receive liquidated damages
set forth in subparagraph (b) below.

                 (b)      Because of the difficulty of measuring economic
losses as a result of a breach by a Shareholder of the foregoing covenant, such
Shareholder agrees to that in the event of a breach of the foregoing covenant
the breaching Shareholder shall be obligated to pay to PRG as liquidated
damages an amount set forth below opposite the year following Closing in which
the breach occurs:

         13.3    REASONABLE RESTRAINT.  It is agreed by the parties that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
Shareholders in light of the activities and business of PRG and PRG Sub on the
date of the execution of this Agreement and the future plans of PRG and
Surviving Corporation.

         13.4    SEVERABILITY; REFORMATION.  The covenants in this Section 13
are severable and separate, and the unenforceability of any specific covenant
shall not affect the provisions of any other covenant.  Moreover, in the event
any court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention
of the parties that such restrictions be enforced to the fullest extent which
the court deems reasonable, and the Agreement shall thereby be reformed.

         13.5    TERM.  It is specifically agreed that the period of five (5)
years stated above, shall be computed by excluding from such computation any
time during which any Shareholder is in violation of any provision of this
Section 13.  The covenants contained in this Section 13 shall have no effect if
the transactions contemplated by this Agreement





                                       24
<PAGE>   26
are not consummated for any reason but otherwise shall not be affected by any
breach of any other provision hereof by any party hereto.


SECTION 14.      NONDISCLOSURE OF CONFIDENTIAL INFORMATION.  The Shareholders
recognize and acknowledge that they had in the past, currently have, and in the
future may possibly have, access to certain confidential information of PRG,
Surviving Corporation or PRG Sub that is valuable, special and unique assets of
PRG's, Surviving Corporation's or PRG Sub's businesses.  The Shareholders agree
that they will not disclose such confidential information to any person, firm,
corporation, association or other entity for any purpose or reason whatsoever,
unless (i) such information becomes available to or known by the public
generally through no fault of the Shareholders, (ii) disclosure is required by
law or the order of any governmental authority under color of law, provided,
that prior to disclosing any information pursuant to this clause (ii), the
Shareholders shall, if possible, give prior written notice thereof to the other
parties hereto, and provide such other parties hereto with the opportunity to
contest such disclosure, (iii) the Shareholders reasonably believe that such
disclosure is required in connection with the defense of a lawsuit against the
disclosing party, or (iv) the Shareholders are the sole and exclusive owner of
such confidential information as a result of the transactions contemplated
hereunder or otherwise.  In the event of a breach or threatened breach by the
Shareholders of the provisions of this Section 14, PRG, Surviving Corporation
or PRG Sub shall be entitled to an injunction restraining the Shareholders from
disclosing, in whole or in part, such confidential information.  Nothing herein
shall be construed as prohibiting PRG, Surviving Corporation or PRG Sub from
pursuing any other available remedy for such breach or threatened breach,
including the recovery of damages. The obligations of the parties under this
Section 14 shall survive the termination of this Agreement.


SECTION 15.      INVESTMENT REPRESENTATIONS.

         15.1    INVESTMENTS; COMPLIANCE WITH LAW.   The Shareholders
acknowledge that the shares of PRG common stock to be delivered to the
Shareholders pursuant to this Agreement have not been and other than as set
forth in the Registration Rights Agreement, will not be registered under the
Securities Act and may not be resold without compliance with the Securities
Act.  The PRG common stock to be acquired by the Shareholders pursuant to this
Agreement is being acquired solely for their own account, for investment
purposes only and with no present intention of distributing, selling or
otherwise disposing of it in connection with a distribution.  The Shareholders
covenant, warrant and represent that none of the shares of PRG common stock
issued to them will be offered, sold, assigned, pledged, hypothecated,
transferred or otherwise disposed of except after full compliance with all of
the applicable provisions of the Securities Act, as amended, and the rules and
regulations of the Securities Exchange Commission and applicable state
securities laws and regulations.  All certificates evidencing shares of PRG
common stock shall bear the following legend in addition to the legend
referenced in Section 15.1.

                 The shares represented hereby have not been registered under
                 the Securities Act of 1933 (the "Act") and may only be sold or
                 otherwise transferred if the holder hereof complies with the
                 Act and applicable securities law or complies with the terms
                 and provisions of that certain Registration Rights Agreement
                 executed among the holder hereof, the Company and certain
                 other persons dated [Closing Date], a copy of which will be
                 provided by the Company upon written request.

In addition, certificates evidencing shares of PRG common stock shall bear any
legend required by the securities or blue sky laws of any state where a
Shareholder resides.

         15.2    ECONOMIC RISK; SOPHISTICATION.  The Shareholders are able to
bear the economic risk of an investment in PRG common stock acquired pursuant
to this Agreement and can afford to sustain a total loss of such investment and
have such knowledge and experience in financial and business matters that they
are capable of evaluating the merits and risks of the proposed investment and
therefore have the capacity to protect their own interests in connection with
the acquisition of the PRG common stock.  The Shareholders or their respective
purchaser representatives have had an adequate opportunity to ask questions and
receive answers from the officers of PRG concerning any and all matters
relating to the background and experience of the officers and directors of PRG,
the plans for the operations of the business of PRG, and any plans for
additional acquisitions and the like.  The Shareholders or





                                       25
<PAGE>   27
their respective purchaser representatives have asked any and all questions in
the nature described in the preceding sentence and all questions have been
answered to their satisfaction.

         15.3    AFFILIATES.  PRG shall be entitled to place legends as
specified in the Affiliates Letters on the certificate(s) evidencing any common
stock to be received by such Affiliates pursuant to the terms of this Agreement
and to issue appropriate stock transfer instructions to the transfer agent for
common stock of PRG, consistent with the terms of such Affiliate Letters.

                                  WITNESSETH:

         WHEREAS, PRG owns a 100% interest in both Physicians Resource Group

         WHEREAS, the parties have determined that a business combination

and partners and accordingly have agreed to effect the Merger (hereinafter
defined) upon the terms and conditions set forth herein;

         WHEREAS, it is intended that for financial accounting purposes the
Merger shall be accounted for as a "pooling of interests."

         NOW THEREFORE, in consideration of the mutual promises and covenants
hereinafter set forth, and for other good and valuable consideration, the
sufficiency of which is hereby acknowledged, the parties hereby agree as
follows:


SECTION 1.       THE MERGER.

         The Merger of PRG Partnership with and into the Partnership shall
occur on the 28th day of June, 1996, to be effective as of 11:59 p.m. on June
30, 1996 ("Closing Date"), unless another date is mutually agreed upon among
the parties hereto, shall be based on the respective representations,
warranties and agreements of the parties hereto, and shall be subject to the
terms and conditions herein stated.

         1.1     MERGER OF PRG PARTNERSHIP INTO THE PARTNERSHIP.  On the
Closing Date, PRG Partnership shall be merged with and into the Partnership in
accordance with this Agreement and the separate legal existence of PRG
Partnership shall thereupon cease (the "Merger").  The Partnership shall be the
surviving entity in the Merger (in such capacity, hereinafter referred to as
the "Surviving Partnership") and shall continue to be governed by the laws of
the State of Florida and the separate legal existence of Surviving Partnership
with all its rights, privileges, powers, immunities, purposes and franchises
shall continue unaffected by the Merger, except as set forth herein.  The
Merger shall have the effects specified in Chapter 620 of the Florida Statutes
for partnerships which elect to be governed by the Revised Uniform Partnership
Act.

         1.2     MERGER STATEMENT.  If all conditions to the Merger set forth
herein have been fulfilled or waived in accordance herewith and this Agreement
shall not have been terminated pursuant to the terms hereof, the parties hereto





                                       1
<PAGE>   3
shall cause to be properly executed and filed on the Closing Date a Statement
of Merger meeting the requirements of Section 620.8907 of the Florida Statutes.
The Merger shall become effective on the Closing Date.

         1.3     CONVERSION OF PARTNERSHIP INTERESTS.  The manner of converting
the partnership interests of the Partners in the Merger shall be as follows:

                 (a)      As a result of the Merger and without any action on
the part of the holder thereof, all of the Partners' interest in the
Partnership on the Closing Date shall, by virtue of the Merger and without any
action on the part of the holder thereof, be converted into the right to
receive the number of shares of PRG common stock set forth on Annex I attached
hereto less the Escrowed Shares (in the aggregate, the "Merger Consideration").
As a result of the Merger and without any action on the part of the holder
thereof, all of the Partners' interest in the Partnership shall be purchased
and shall cease to exist, and each Partner shall be deemed to be dissociated
from the Partnership as of the Closing Date (as provided in Section 620.8906 of
the Florida Statutes) and such Partner shall thereafter cease to have any
rights with respect to his interest in the Partnership, except the right to
receive, without interest, the Merger Consideration.

                 (b)      On the Closing Date, all of the PRG Partnership
interests outstanding as of the Closing Date shall be surrendered in exchange
for  an equal interest in the Surviving Partnership.

         1.4     [INTENTIONALLY DELETED].

         1.5     ESCROW.  In addition to the shares issuable to the Partners at
Closing, PRG shall deposit in escrow 4,870 shares of PRG Common Stock (the
"Escrowed Shares") pursuant to the terms of an Escrow Agreement (the "Escrow
Agreement") in substantially the form attached hereto as Exhibit 1.5 and with
such changes to be agreed upon between the parties, to be entered into among
Partners, the Partnership, PRG Partnership, PRG and the person named therein as
escrow agent ("Escrow Agent").  The Escrowed Shares shall be issued in the name
of the Escrow Agent, as escrow agent.  The Escrowed Shares shall be released
from escrow, after provision for any Damages for which PRG or PRG Partnership
may be entitled to indemnification pursuant to Article XI in accordance with
the terms of the Escrow Agreement.

         1.6     SUBSEQUENT ACTIONS. If, at any time after the Closing Date,
the Surviving Partnership shall consider or be advised that any deeds, bills of
sale, assignments, assurances or any other actions or things are necessary or
desirable to vest, perfect or confirm of record or otherwise in the Surviving
Partnership its right, title or interest in, to or under any of the rights,
properties or assets of the Partnership or PRG Partnership acquired or to be
acquired by the Surviving Partnership as a result of, or in connection with,
the Merger or otherwise to carry out this Agreement, and to effect the purchase
and cancellation of the Partners' interest in the Partnership in return for the
consideration set forth in this Agreement, the partners of the Surviving
Partnership or their duly authorized officers, directors and agents, shall be
authorized to execute and deliver, in the name and on behalf of the
Partnership, each Partner and PRG Partnership or otherwise, to carry out all
such deeds, bills of sale, assignments and assurances and to take and do, in
the name and on behalf of the Partnership and PRG Partnership or otherwise, all
such other actions and things as may be necessary or desirable to vest, perfect
or confirm any and all right, title and interest in, to and under such rights,
properties or assets in the Surviving Partnership or otherwise to carry out
this Agreement.

         1.7     ASSUMPTIONS OF OR PREPAYMENT OF DEBT.  In connection with the
Merger, PRG shall assume or prepay all indebtedness of the Partnership and
shall take such actions as may be necessary, desirable or appropriate to
absolve and release the Partners from any further personal liability with
respect to such indebtedness.

                 PARTNERS.

         The Partnership and the Partners, jointly (with respect to

amount, as of the Balance Sheet Date and determined in conformity with
generally accepted accounting principles and the past practices employed by the
Partnership, of the Partnership's (i) accounts receivable, net of allowances
for uncollectible and doubtful amounts ("Accounts Receivable") and (ii)
accounts payable and  accrued liabilities (other than the current portion of
long-term debt) ("Accounts Payable").  Exhibit 2.16 contains a true and
accurate (i) list of all Accounts Receivable, (ii) list of all Accounts Payable
and (iii) statement of the working capital ("Working Capital") of the
Partnership as of the Balance Sheet Date.  The Partnership maintains its
accounting records in sufficient detail to substantiate the accounts receivable
reflected on the Balance Sheet and has given and will give to PRG Partnership
full and complete access to those records, including the right to make copies
therefrom.  Since the Balance Sheet Date, the Partnership has not changed any
principle or practice with respect to the recordation of accounts receivable or
the calculation of reserves therefor, or any material collection, discount or
write-off policy or procedure.

         2.17    TAXES.  The Partnership has filed all tax returns required to
be filed by it, and made all payments of taxes, including any interest, penalty
or addition thereto, required to be made by it, with respect to income taxes,
real and personal property taxes, sales taxes, use taxes, employment taxes,
excise taxes and other taxes due and payable on or before the date of this
Agreement.  All such tax returns are complete and accurate in all respects and
properly reflect the relevant taxes for the periods covered thereby.  The

for the current period not yet due and payable and sales, use, employment and
similar taxes for periods as to which such taxes have not yet become due and
payable.   The unpaid taxes of the Partnership did not, as of the Balance Sheet
Date, exceed the reserve for taxes (rather than any reserve for deferred taxes
established to reflect timing differences between book and income tax income)
set forth on the face of the Balance Sheet (rather than in any notes thereto),
as adjusted for the passage of time through the Closing Date (in accordance
with the past custom and practice of the Partnership).  The Partnership and the
Partners have not received any notice that any tax deficiency or delinquency
has been asserted against the Partnership.  There are no audits relating to
taxes of the Partnership threatened, pending or in process.  The Partnership is
not currently the beneficiary of any waiver of any statute of limitations in
respect of taxes nor of any extension of time within which to file any tax
return or to pay any tax assessment or deficiency.  There are no liens or
encumbrances relating to taxes on or threatened against any of the assets of
the Partnership.  The Partnership has withheld and paid all taxes required by
law to have been withheld and paid by it.  Neither the Partnership nor any
predecessor of the Partnership is or has been a party to any tax allocation or
sharing agreement or a member of an affiliated group of corporations filing a
consolidated federal income tax return.  The Partnership has delivered to PRG
Partnership correct and complete copies of the Partnership's three most
recently filed annual state and federal income tax returns, together with all
examination reports and statements of deficiencies assessed against or agreed
to by the Partnership during the three calendar year period preceding the date

commissions or finder's or similar fees in connection with the transactions
contemplated by this Agreement which may be now or hereafter asserted against
PRG, PRG Partnership, the Partnership or the Partners resulting from any action
taken by the Partnership or the Partners or their respective agents or
employees, or any of them.

         2.19    LIABILITIES; DEBT.  Except to the extent reflected or reserved
against on the Balance Sheet, the Partnership did not have, as of the Balance
Sheet Date, and has not incurred since that date and will not have occurred as
of the Closing Date, any liabilities or obligations of any nature required to
be disclosed in accordance with GAAP, whether accrued, absolute, contingent or
otherwise, and whether due or to become due, other than those incurred in the
ordinary course of business.  The Partnership and the Partners do not know, or
have reasonable grounds to know, of any basis for the assertion against the

nature in any amount not fully reflected or reserved against on the Balance
Sheet which is required to be disclosed in accordance with GAAP, or of any
claim or liability of any nature arising since that date other than those

and enforceable policies in such amounts are outstanding and duly in force and
will remain duly in force through the Closing Date.  All such policies are
described in Exhibit 2.20 attached hereto and true and correct copies have been
delivered to PRG Partnership.  Neither the Partnership nor any Partner has
received notice or other communication from the issuer of any such insurance
policy cancelling or amending such policy or threatening to do so.  The
Partnership has no outstanding claims, settlements or premiums owed against any
insurance policy.

         2.21    EMPLOYEE BENEFIT PLANS.  The Partnership has no employees and

any other restriction or any judgment, order, writ, injunction, decree, rule or
regulation that materially and adversely affects the condition (financial or
otherwise), operations, assets, liabilities, business or prospects of the
Partnership.

         2.23    COMPLIANCE WITH LAWS IN GENERAL.  The Partnership and the
Partners have complied with all applicable laws, rules, regulations and
licensing requirements, including, without limitation, the Federal
Environmental Protection Act, the Occupational Safety and Health Act, the

Indemnified Person receives written notice of the commencement of any action or
other proceeding in respect of which indemnification or reimbursement may be
sought hereunder, or within such lesser time as may be provided by law for the
defense of such action or proceeding, such Indemnified Person shall notify
Indemnitor thereof.  If any such action or other proceeding shall be brought
against any Indemnified Person, Indemnitor shall, upon written notice given
within a reasonable time following receipt by Indemnitor of such notice from
Indemnified Person, be entitled to assume the defense of such action or
proceeding with counsel chosen by Indemnitor and reasonably satisfactory to
Indemnified Person; provided, however, that any Indemnified Person may at its
own expense retain separate counsel to participate in such defense.
Notwithstanding the foregoing, Indemnified Person shall have the right to
employ separate counsel at Indemnitor's expense and to control its own defense
of such action or proceeding if, in the reasonable opinion of counsel to such
Indemnified Person, (a) there are or may be legal defenses available to such

additional to those available to Indemnitor and which could not be adequately
advanced by counsel chosen by Indemnitor, or (b) a conflict or potential
conflict exists between Indemnitor and such Indemnified Person that would make
such separate representation advisable; provided, however, that in no event
shall Indemnitor be required to pay fees and expenses hereunder for more than
one firm of attorneys of Indemnified Person in any jurisdiction in any one
action or proceeding or group of related actions or proceedings.  Indemnitor
shall not, without the prior written consent of any Indemnified Person, settle
or compromise or consent to the entry of any judgment in any pending or
threatened claim, action or proceeding to which such Indemnified Person is a
party unless such settlement, compromise or consent includes an unconditional
release of such Indemnified Person from all liability arising or potentially
arising from or by reason of such claim, action or proceeding.

         9.5     LIMITATION ON INDEMNIFICATION.  Notwithstanding anything

and filed any tax returns, statements and reports ("Tax Returns") of Surviving
Partnership covering taxable periods ending on or before the Closing Date which
have not been filed on or before the Closing Date.  Partners shall, jointly and
severally, within fifteen (15) days after payment thereof and receipt of notice

after payment thereof and notice of such payment, reimburse, indemnify and hold
harmless PRG and the Surviving Partnership for all Taxes for any Straddle
Period, to the extent related to the portion of the Straddle Period ending on
the Closing Date.  For such purposes, the portion of any Tax attributable to
the portions of a Straddle Period ending on the Closing Date and beginning
after the Closing Date shall be determined by apportioning the Tax for the
entire Straddle Period among such periods based on the number of days in each
such period, provided that, in the case of Taxes based upon or related to
income or receipts, such portion shall be the amount of Tax which would have
been due if the relevant Straddle Period ended on the Closing Date.  Any
credits relating to a Straddle Period shall be taken into account as though the
relevant Straddle Period ended on the Closing Date.  All determinations
necessary to give effect to the foregoing allocations shall be made in a manner
consistent with prior practices of the Partnership.

                 (c)      The Partnership, Partners, PRG, Surviving Partnership
and PRG Partnership shall reasonably cooperate with each other in connection
with the filing of Tax Returns pursuant to this Section 11.5(c) and any audit,
litigation or other proceeding with respect to Taxes.  Such cooperation shall

representation or warranty of PRG or PRG Partnership contained in this
Agreement or in any certificate or other document executed and delivered by PRG
or PRG Partnership pursuant to this Agreement is or becomes untrue or breached
in any material respect or if PRG or PRG Partnership fails to comply in any

         (e)     by PRG at any time prior to the Closing Date if PRG determines
in its sole discretion as the result of its legal, financial and operational
due diligence with respect to the Partnership, that such termination is
desirable and in the best interests of PRG; or

         (f)     by the Partners if counsel for the Partners shall determine,
in its reasonable good faith judgment, that the provisions of Section 11.3(III)
shall not be satisfactory to protect the Partners with respect to the claims
discussed therein.


SECTION 11.      NONDISCLOSURE OF CONFIDENTIAL INFORMATION.  The Partners
recognize and acknowledge that they had in the past, currently have, and in the
future may possibly have, access to certain confidential information of PRG,
Surviving Partnership or PRG Partnership that is valuable, special and unique
assets of PRG's, Surviving Partnership's or PRG Partnership's businesses.  The
Partners agree that they will not disclose such confidential information to any
person, firm, corporation, association or other entity for any purpose or
reason whatsoever, unless (i) such information becomes available to or known by
the public generally through no fault of the Partners, (ii) disclosure is
required by law or the order of any governmental authority under color of law,
provided, that prior to disclosing any information pursuant to this clause
(ii), the Partners shall, if possible, give prior written notice thereof to the
other parties hereto, and provide such other parties hereto with the
opportunity to contest such disclosure, (iii) the Partners reasonably believe
that such disclosure is required in connection with the defense of a lawsuit
against the disclosing party, or (iv) the Partners are the sole and exclusive
owner of such confidential information as a result of the transactions
contemplated hereunder or otherwise.  In the event of a breach or threatened
breach by the Partners of the provisions of this Section 14, PRG, Surviving
Partnership or PRG Partnership shall be entitled to an injunction restraining
the Partners from disclosing, in whole or in part, such confidential
information.  Nothing herein shall be construed as prohibiting PRG, Surviving
Partnership or PRG Partnership from pursuing any other available remedy for
such breach or threatened breach, including the recovery of damages. The
obligations of the parties under this Section 14 shall survive the termination
of this Agreement.

SECTION 12.      INVESTMENT REPRESENTATIONS.

         12.1    ECONOMIC RISK; SOPHISTICATION.  The Partners are able to bear
the economic risk of an investment in PRG common stock acquired pursuant to
this Agreement and can afford to sustain a total loss of such investment and
have such knowledge and experience in financial and business matters that they
are capable of evaluating the merits and risks of the proposed investment and
therefore have the capacity to protect their own interests in connection with
the acquisition of the PRG common stock.  The Partners or their respective
purchaser representatives have had an adequate opportunity to ask questions and
receive answers from the officers of PRG concerning any and all matters
relating to the background and experience of the officers and directors of PRG,
the plans for the operations of the business of PRG, and any plans for
additional acquisitions and the like.  The Partners or their respective
purchaser representatives have asked any and all questions in the nature
described in the preceding sentence and all questions have been answered to
their satisfaction.

         12.2    AFFILIATES.  PRG shall be entitled to place legends as
specified in the Affiliates Letters on the certificate(s) evidencing any common
stock to be received by such Affiliates pursuant to the terms of this Agreement
and to issue appropriate stock transfer instructions to the transfer agent for
common stock of PRG, consistent with the terms of such Affiliate Letters.

         NOW THEREFORE, in consideration of the mutual promises and covenants
hereinafter set forth, and for other good and valuable consideration, the
sufficiency of which is hereby acknowledged, the parties hereby agree as
follows:


SECTION 1.       THE MERGER.

         The Merger of PRG Partnership with and into the Partnership shall
occur on the 28th day of June, 1996, to be effective as of 11:59 p.m. on June

the parties hereto, shall be based on the respective representations,
warranties and agreements of the parties hereto, and shall be subject to the
terms and conditions herein stated.

         1.1     MERGER OF PRG PARTNERSHIP INTO THE PARTNERSHIP.  On the
Closing Date, PRG Partnership shall be merged with and into the Partnership in
accordance with this Agreement and the separate legal existence of PRG

surviving entity in the Merger (in such capacity, hereinafter referred to as
the "Surviving Partnership") and shall continue to be governed by the laws of
the State of Florida and the separate legal existence of Surviving Partnership
with all its rights, privileges, powers, immunities, purposes and franchises

the part of the holder thereof, all of the Partners' interest in the
Partnership on the Closing Date shall, by virtue of the Merger and without any
action on the part of the holder thereof, be converted into the right to
receive the number of shares of PRG common stock set forth on Annex I attached

As a result of the Merger and without any action on the part of the holder
thereof, all of the Partners' interest in the Partnership shall be purchased
and shall cease to exist, and each Partner shall be deemed to be dissociated
from the Partnership as of the Closing Date (as provided in Section 620.8906 of

         1.5     ESCROW.  In addition to the shares issuable to the Partners at
Closing, PRG shall deposit in escrow 4,870 shares of PRG Common Stock (the
"Escrowed Shares") pursuant to the terms of an Escrow Agreement (the "Escrow
Agreement") in substantially the form attached hereto as Exhibit 1.5 and with
such changes to be agreed upon between the parties, to be entered into among
Partners, the Partnership, PRG Partnership, PRG and the person named therein as

may be entitled to indemnification pursuant to Article XI in accordance with
the terms of the Escrow Agreement.

the Surviving Partnership shall consider or be advised that any deeds, bills of
sale, assignments, assurances or any other actions or things are necessary or
desirable to vest, perfect or confirm of record or otherwise in the Surviving
Partnership its right, title or interest in, to or under any of the rights,
properties or assets of the Partnership or PRG Partnership acquired or to be

accurate (i) list of all Accounts Receivable, (ii) list of all Accounts Payable
and (iii) statement of the working capital ("Working Capital") of the
Partnership as of the Balance Sheet Date.  The Partnership maintains its
accounting records in sufficient detail to substantiate the accounts receivable
reflected on the Balance Sheet and has given and will give to PRG Partnership
full and complete access to those records, including the right to make copies
therefrom.  Since the Balance Sheet Date, the Partnership has not changed any

real and personal property taxes, sales taxes, use taxes, employment taxes,
excise taxes and other taxes due and payable on or before the date of this
Agreement.  All such tax returns are complete and accurate in all respects and
properly reflect the relevant taxes for the periods covered thereby.  The

for the current period not yet due and payable and sales, use, employment and
similar taxes for periods as to which such taxes have not yet become due and
payable.   The unpaid taxes of the Partnership did not, as of the Balance Sheet
Date, exceed the reserve for taxes (rather than any reserve for deferred taxes
established to reflect timing differences between book and income tax income)
set forth on the face of the Balance Sheet (rather than in any notes thereto),
as adjusted for the passage of time through the Closing Date (in accordance
with the past custom and practice of the Partnership).  The Partnership and the
Partners have not received any notice that any tax deficiency or delinquency
has been asserted against the Partnership.  There are no audits relating to
taxes of the Partnership threatened, pending or in process.  The Partnership is
not currently the beneficiary of any waiver of any statute of





                                       7
<PAGE>   9
limitations in respect of taxes nor of any extension of time within which to
file any tax return or to pay any tax assessment or deficiency.  There are no
liens or encumbrances relating to taxes on or threatened against any of the
assets of the Partnership.  The Partnership has withheld and paid all taxes
required by law to have been withheld and paid by it.  Neither the Partnership
nor any predecessor of the Partnership is or has been a party to any tax
allocation or sharing agreement or a member of an affiliated group of
corporations filing a consolidated federal income tax return.  The Partnership
has delivered to PRG Partnership correct and complete copies of the
Partnership's three most recently filed annual state and federal income tax
returns, together with all examination reports and statements of deficiencies
assessed against or agreed to by the Partnership during the three calendar year
period preceding the date of this Agreement.  The Partnership has neither made

IN CONNECTION WITH INDEMNITOR'S OBLIGATION TO INDEMNIFY FOR EXPENSES,
INDEMNITOR SHALL REIMBURSE EACH INDEMNIFIED PERSON FOR ALL SUCH EXPENSES AS
THEY ARE INCURRED BY SUCH INDEMNIFIED PERSON, PROVIDED THAT SUCH INDEMNIFIED
PERSON AGREES IN WRITING TO REFUND ALL SUCH REIMBURSED EXPENSES IF AND TO THE
EXTENT THAT IT IS FINALLY JUDICIALLY DETERMINED THAT SUCH INDEMNIFIED PERSON IS
NOT ENTITLED TO INDEMNIFICATION HEREUNDER.

         9.4     INDEMNIFICATION PROCEDURE.  Within sixty (60) days after
Indemnified Person receives written notice of the commencement of any action or
other proceeding in respect of which indemnification or reimbursement may be
sought hereunder, or within such lesser time as may be provided by law for the
defense of such action or proceeding, such Indemnified Person shall notify
Indemnitor thereof.  If any such action or other proceeding shall be brought
against any Indemnified Person, Indemnitor shall, upon written notice given
within a reasonable time following receipt by Indemnitor of such notice from
Indemnified Person, be entitled to assume the defense of such action or
proceeding with counsel chosen by Indemnitor and reasonably satisfactory to
Indemnified Person; provided, however, that any Indemnified Person may at its
own expense retain separate counsel to participate in such defense.
Notwithstanding the foregoing, Indemnified Person shall have the right to
employ separate counsel at Indemnitor's expense and to control its own defense
of such action or proceeding if, in the reasonable opinion of counsel to such
Indemnified Person, (a) there are or may be legal defenses available to such
Indemnified Person or to other Indemnified Persons that are different from or
additional to those available to Indemnitor and which could not be adequately
advanced by counsel chosen by Indemnitor, or (b) a conflict or potential
conflict exists between Indemnitor and such Indemnified Person that would make
such separate representation advisable; provided, however, that in no event
shall Indemnitor be required to pay fees and expenses hereunder for more than
one firm of attorneys of Indemnified Person in any jurisdiction in any one
action or proceeding or group of related actions or proceedings.  Indemnitor
shall not, without the prior written consent of any Indemnified Person, settle
or compromise or consent to the entry of any judgment in any pending or
threatened claim, action or proceeding to which such Indemnified Person is a
party unless such settlement, compromise or consent includes an unconditional
release of such Indemnified Person from all liability arising or potentially
arising from or by reason of such claim, action or proceeding.

         9.5     LIMITATION ON INDEMNIFICATION.  Notwithstanding anything
contained herein to the contrary, any indemnification by the Partnership and
Partners in favor of PRG or PRG Partnership shall not exceed in all cases the
Escrowed Shares, and any indemnification by PRG and PRG Partnership in favor of
the Partnership and Partners shall not exceed in all cases (other than as set
forth in Section 11.2(III) $139,392.  Furthermore, other than claims pursuant

no claim for Damages shall be made by any party more than one (1) year after
the Closing Date.

         9.6     CERTAIN TAX MATTERS.

                 (a)      PRG shall prepare and file or cause to be prepared
and filed any tax returns, statements and reports ("Tax Returns") of Surviving
Partnership covering taxable periods ending on or before the Closing Date which
have not been filed on or before the Closing Date.  Partners shall, jointly and
severally, within fifteen (15) days after payment thereof and receipt of notice
of such payment, reimburse, indemnify and hold harmless PRG and the Surviving
Partnership for all taxes, and all related interest, penalties and additions to
tax ("Taxes"), with respect to taxable periods of the Partnership ending on or
before the Closing Date.

                 (b)      PRG shall prepare and file or cause to be prepared
and filed any Tax Returns of Surviving Partnership covering taxable periods
which begin before the Closing Date and end after the Closing Date ("Straddle
Periods"). Partners shall, jointly and severally, within fifteen (15) days
after payment thereof and notice of such payment, reimburse, indemnify and hold
harmless PRG and the Surviving Partnership for all Taxes for any Straddle
Period, to the extent related to the portion of the Straddle Period ending on
the Closing Date.  For such purposes, the portion of any Tax attributable to
the portions of a Straddle Period ending on the Closing Date and beginning
after the Closing Date shall be determined by apportioning the Tax for the
entire Straddle Period among such periods based on the number of days in each
such period, provided that, in the case of Taxes based upon or related to
income or receipts, such portion shall be the amount of Tax which would have
been due if the relevant Straddle Period ended on the Closing Date.  Any
credits relating to a Straddle Period shall be taken into account as though the
relevant Straddle Period ended





                                       17
<PAGE>   19
on the Closing Date.  All determinations necessary to give effect to the
foregoing allocations shall be made in a manner consistent with prior practices
of the Partnership.

                 (c)      The Partnership, Partners, PRG, Surviving Partnership
and PRG Partnership shall reasonably cooperate with each other in connection
with the filing of Tax Returns pursuant to this Section 11.5(c) and any audit,
litigation or other proceeding with respect to Taxes.  Such cooperation shall
include the provision of copies, at the requesting party's expense, of records
and information relevant to any such Tax Return or proceeding and making
employees available on a mutually convenient basis to provide additional
information and explanation of any material provided hereunder.

warranty of the Partnership or any Partner contained in this Agreement or in
any certificate or other document executed and delivered by the Partnership or
any Partner pursuant to this Agreement is or becomes untrue or breached in any
material respect or if the Partnership or any Partners fails to comply in any
material respect with any covenant or agreement contained herein, and any such
misrepresentation, noncompliance or breach is not cured, waived or eliminated
within twenty (20) days after receipt of written notice thereof;

         (c)     at any time by the Partnership or the Partners if any
representation or warranty of PRG or PRG Partnership contained in this
Agreement or in any certificate or other document executed and delivered by PRG
or PRG Partnership pursuant to this Agreement is or becomes untrue or breached
in any material respect or if PRG or PRG Partnership fails to comply in any
material respect with any covenant or agreement contained herein and such
misrepresentation, noncompliance or bread is not cured, waived or eliminated
within twenty (20) days after receipt of written notice thereof;

         (d)     by PRG, PRG Partnership, the Partnership or the Partners if
the merger contemplated hereby shall not have been consummated by June 28,

         (e)     by PRG at any time prior to the Closing Date if PRG determines
in its sole discretion as the result of its legal, financial and operational
due diligence with respect to the Partnership, that such termination is
desirable and in the best interests of PRG; or

         (f)     by the Partners if counsel for the Partners shall determine,
in its reasonable good faith judgment, that the provisions of Section 11.3(III)
shall not be satisfactory to protect the Partners with respect to the claims
discussed therein.


SECTION 11.      NONDISCLOSURE OF CONFIDENTIAL INFORMATION.  The Partners
recognize and acknowledge that they had in the past, currently have, and in the
future may possibly have, access to certain confidential information of PRG,
Surviving Partnership or PRG Partnership that is valuable, special and unique
assets of PRG's, Surviving Partnership's or PRG Partnership's businesses.  The
Partners agree that they will not disclose such confidential information to any
person, firm, corporation, association or other entity for any purpose or
reason whatsoever, unless (i) such information becomes available to or known by
the public generally through no fault of the Partners, (ii) disclosure is
required by law or the order of any governmental authority under color of law,
provided, that prior to disclosing any information pursuant to this clause
(ii), the Partners shall, if possible, give prior written notice thereof to the
other parties hereto, and provide such other parties hereto with the
opportunity to contest such disclosure, (iii) the Partners reasonably believe
that such disclosure is required in connection with the defense of a lawsuit
against the disclosing party, or (iv) the Partners are the sole and exclusive
owner of such confidential information as a result of the transactions
contemplated hereunder or otherwise.  In the event of a breach or threatened
breach by the Partners of the provisions of this Section 14, PRG, Surviving
Partnership or PRG Partnership shall be entitled to an injunction restraining
the Partners from disclosing, in whole or in part, such confidential
information.  Nothing herein shall be construed as prohibiting PRG,





                                       18
<PAGE>   20
Surviving Partnership or PRG Partnership from pursuing any other available
remedy for such breach or threatened breach, including the recovery of damages.
The obligations of the parties under this Section 14 shall survive the
termination of this Agreement.


SECTION 12.      INVESTMENT REPRESENTATIONS.

         12.1    ECONOMIC RISK; SOPHISTICATION.  The Partners are able to bear
the economic risk of an investment in PRG common stock acquired pursuant to
this Agreement and can afford to sustain a total loss of such investment and
have such knowledge and experience in financial and business matters that they
are capable of evaluating the merits and risks of the proposed investment and
therefore have the capacity to protect their own interests in connection with
the acquisition of the PRG common stock.  The Partners or their respective
purchaser representatives have had an adequate opportunity to ask questions and
receive answers from the officers of PRG concerning any and all matters
relating to the background and experience of the officers and directors of PRG,
the plans for the operations of the business of PRG, and any plans for
additional acquisitions and the like.  The Partners or their respective
purchaser representatives have asked any and all questions in the nature
described in the preceding sentence and all questions have been answered to
their satisfaction.

         12.2    AFFILIATES.  PRG shall be entitled to place legends as
specified in the Affiliates Letters on the certificate(s) evidencing any common
stock to be received by such Affiliates pursuant to the terms of this Agreement
and to issue appropriate stock transfer instructions to the transfer agent for
common stock of PRG, consistent with the terms of such Affiliate Letters.

                      AGREEMENT AND PLAN OF REORGANIZATION


         This AGREEMENT AND PLAN OF REORGANIZATION, made and executed as of the
30th day of June, 1996, is by and among PRG TX ACQUISITION CORP. I, a Texas
corporation ("PRG Sub"); PHYSICIANS RESOURCE GROUP, INC., a Delaware
corporation ("PRG"); SOUTH TEXAS RETINA AFFILIATES, INC., a Texas corporation
(the Company"), SOUTH TEXAS RETINA CONSULTANTS, L.L.P., a Texas limited
liability partnership ("LLP") and CHARLES H. CAMPBELL, M.D., P.A., a Texas
professional association ("PA") (collectively, the LLP and the PA are referred
to herein as the "Practice") and CHARLES H. CAMPBELL, M.D., an individual
resident of the State of Texas ("Shareholder").

                                  WITNESSETH:

         WHEREAS, the Practice operates an ophthalmology practice in Corpus
Christi, Texas;

         WHEREAS, the Company owns all of the assets (other than the
physicians) used in the business of LLP and has a service arrangement with the
LLP whereby the Company performs all non-medical services for LLP; and

         WHEREAS, Shareholder is the only Shareholder of the Company, and the
Shareholder and PA are the only partners of LLP;

         WHEREAS, PRG Sub is engaged in the business of acquiring the assets of
and managing non-medical aspects of ophthalmology practices and is a
wholly-owned subsidiary of PRG; and

         WHEREAS, the Boards of Directors of each of the Company, PRG and PRG
Sub have determined that a business combination between the parties is in the
best interests of their respective companies and stockholders and accordingly
have agreed to effect the Merger (hereinafter defined) upon the terms and
conditions set forth herein;

         WHEREAS, it is intended that for federal income tax purposes the
Merger shall qualify as a reorganization within the meaning of Section 368(a)
of the Internal Revenue Code of 1986, as amended (the "Code").

         NOW THEREFORE, in consideration of the mutual promises and covenants
hereinafter set forth, and for other good and valuable consideration, the
sufficiency of which is hereby acknowledged, the parties hereby agree as
follows:


SECTION 1.       THE MERGER.

         The Merger of PRG Sub with and into the Company shall occur on the

the parties hereto, shall be based on the respective representations,
warranties and agreements of the parties hereto, and shall be subject to the
terms and conditions herein stated.

         1.1     MERGER OF PRG SUB INTO THE COMPANY.  On the Closing Date, PRG
Sub shall be merged with and into the Company in accordance with this Agreement
and the separate corporate existence of PRG Sub shall thereupon cease (the
"Merger").  The Merger is intended to be a "tax-free reorganization" pursuant
to Section 368(a) of the Code and the parties hereto shall not report the
transaction in a manner inconsistent therewith or otherwise take any action
that would prevent the Merger from qualifying as such; provided, however, that
the actual tax effect of the transactions contemplated by this Agreement is not
a condition precedent to the closing of the transactions contemplated hereby
and no party hereto makes or has made any representation, warranty or covenant
to any other party hereto as to such qualification.  The Company shall be the
surviving corporation in the Merger (in such capacity, hereinafter referred to
as the "Surviving Corporation") and shall continue to be governed by the laws
of the State of Texas and the separate corporate existence of Surviving
Corporation with all its rights, privileges, powers, immunities, purposes and
franchises shall continue unaffected by the Merger, except as set forth herein.
The Merger shall have the effects specified in the Texas Business Corporation
Act ("TBCA").

                                       19
<PAGE>   24
INCURRED BY SUCH INDEMNIFIED PERSON, PROVIDED THAT SUCH INDEMNIFIED PERSON
AGREES IN WRITING TO REFUND ALL SUCH REIMBURSED EXPENSES IF AND TO THE EXTENT
THAT IT IS FINALLY JUDICIALLY DETERMINED THAT SUCH INDEMNIFIED PERSON IS NOT
ENTITLED TO INDEMNIFICATION HEREUNDER.

         10.4    INDEMNIFICATION PROCEDURE.  (a)  Within sixty (60) days after
Indemnified Person receives written notice of the commencement of any action or
other proceeding in respect of which indemnification or reimbursement may be
sought hereunder, or within such lesser time as may be provided by law for the
defense of such action or proceeding, such Indemnified Person shall notify
Indemnitor thereof.  Notwithstanding the foregoing, failure of Indemnified
Person to give such notice shall not affect the right of Indemnified Party to
be indemnified pursuant to the terms hereof.  If any such action or other
proceeding shall be brought against any Indemnified Person, Indemnitor shall,
upon written notice given within a reasonable time following receipt by
Indemnitor of such notice from Indemnified Person, be entitled to assume the
defense of such action or proceeding with counsel chosen by Indemnitor and
reasonably satisfactory to Indemnified Person; provided, however, that any
Indemnified Person may at its own expense retain separate counsel to
participate in such defense.  Notwithstanding the foregoing, Indemnified Person
shall have the right to employ separate counsel at Indemnitor's expense and to
control its own defense of such action or proceeding if, in the reasonable
opinion of counsel to such Indemnified Person, (a) there are or may be legal
defenses available to such Indemnified Person or to other Indemnified Persons
that are different from or additional to those available to Indemnitor and
which could not be adequately advanced by counsel chosen by Indemnitor, or (b)
a conflict or potential conflict exists between Indemnitor and such Indemnified
Person that would make such separate representation advisable; provided,
however, that in no event shall Indemnitor be required to pay fees and expenses
hereunder for more than one firm of attorneys of Indemnified Person in any
jurisdiction in any one action or proceeding or group of related actions or
proceedings.  Indemnitor shall not, without the prior written consent of any
Indemnified Person, settle or compromise or consent to the entry of any
judgment in any pending or threatened claim, action or proceeding to which such
Indemnified Person is a party unless such settlement, compromise or consent
includes an unconditional release of such Indemnified Person from all liability
arising or potentially arising from or by reason of such claim, action or
proceeding.

                 (b)      Notwithstanding the provisions of Section 10.3, the
Shareholder, the Company and the Practice shall not be required to indemnify
PRG unless, and to the extent that, the aggregate amount of damages, losses,
liabilities, costs and other sums ("Damages") incurred by PRG and PRG Sub
unless, and to the extent that, the aggregate amount of Damages incurred by PRG
and PRG Sub shall exceed an amount equal to $49,000.  Notwithstanding the
provisions of Section 10.2, PRG and PRG Sub shall not be required to indemnify
the Company, the Practice and the Shareholder unless, and to the extent that
the aggregate amount of Damages incurred by the Shareholder shall exceed an
amount equal to $49,000.

         10.5    CERTAIN TAX MATTERS.

                 (a)      PRG shall prepare and file or cause to be prepared
and filed any tax returns, statements and reports ("Tax Returns") of Surviving
Corporation covering taxable periods ending on or before the Closing Date which
have not been filed on or before the Closing Date.  Shareholder shall, within
fifteen (15) days after payment thereof and receipt of notice of such payment,
reimburse, indemnify and hold harmless PRG and the Surviving Corporation for
all taxes, and all related interest, penalties and additions to tax ("Taxes"),
with respect to taxable periods of the Company ending on or before the Closing
Date.

                 (b)      PRG shall prepare and file or cause to be prepared
and filed any Tax Returns of Surviving Corporation covering taxable periods
which begin before the Closing Date and end after the Closing Date ("Straddle
Periods"). Shareholder shall, within fifteen (15) days after payment thereof
and notice of such payment, reimburse, indemnify and hold harmless PRG and the
Surviving Corporation for all Taxes for any Straddle Period, to the extent
related to the portion of the Straddle Period ending on the Closing Date.  For
such purposes, the portion of any Tax attributable to the portions of a
Straddle Period ending on the Closing Date and beginning after the Closing Date
shall be determined by apportioning the Tax for the entire Straddle Period
among such periods based on the number of days in each such period, provided
that, in the case of Taxes based upon or related to income or receipts, such
portion shall be the amount of Tax which would have been due if the relevant
Straddle Period ended on the Closing Date.  Any credits relating to a Straddle
Period shall be taken into account as though the relevant Straddle Period ended
on the Closing Date.  All determinations necessary to give effect to the
foregoing allocations shall be made in a manner consistent with prior practices
of the Company.

                 (c)      The Company, Shareholder, PRG, Surviving Corporation
and PRG Sub shall reasonably cooperate with each other in connection with the
filing of Tax Returns pursuant to this Section 10.5(c) and any audit,
litigation or other proceeding with respect to Taxes.  Such cooperation shall
include the provision of copies, at the requesting party's expense, of records
and information relevant to any such Tax Return or proceeding and making
employees available on a mutually convenient basis to provide additional
information and explanation of any material provided hereunder.

         10.6    RIGHT OF SETOFF. In the event of any breach of warranty,
representation, covenant or agreement by the Company or the Shareholder giving
rise to indemnification under Section 10.3 or Section 10.5 hereof, PRG,
Surviving Corporation or PRG Sub shall be entitled to offset the amount of
damages incurred by it as a result of such breach of warranty, representation,
covenant or agreement against any amounts payable by PRG, PRG Sub or Surviving
Corporation, including the amounts payable under the Service Agreement.


SECTION 11.      TERMINATION.  This Agreement may be terminated:

                 (a)      at any time by mutual agreement of all parties;

                 (b)      at any time by PRG or PRG Sub if any representation
or warranty of the Company, the Practice or Shareholder contained in this
Agreement or in any certificate or other document executed and delivered by the
Company, the Practice or Shareholder pursuant to this Agreement is or becomes
untrue or breached in any material respect or if the Company, the Practice or
Shareholder fails to comply in any material respect with any covenant or
agreement contained herein, and any such misrepresentation, noncompliance or
breach is not cured, waived or eliminated within twenty (20) days after receipt
of written notice thereof;

                 (c)      at any time by the Company, the Practice or the
Shareholder if any representation or warranty of PRG or PRG Sub contained in
this Agreement or in any certificate or other document executed and delivered
by PRG or PRG Sub pursuant to this Agreement is or becomes untrue in any
material respect or PRG or PRG Sub fails to comply in any material respect with
any covenant or agreement contained herein and such misrepresentation,
noncompliance or bread is not cured, waived or eliminated within twenty (20)
days of written notice thereof;

                 (d)      by PRG, PRG Sub, the Company, the Practice or the
Shareholder if the merger contemplated hereby shall not have been consummated
by July 4, 1996; or





                                       21
<PAGE>   26
                 (e)      by PRG at any time prior to the Closing Date if PRG
determines in its sole discretion as the result of its legal, financial and
operational due diligence with respect to the Company or the Practice, that
such termination is desirable and in the best interests of PRG.


SECTION 12.      NONCOMPETITION.

         12.1    PROHIBITED ACTIVITIES.  In order to protect PRG, PRG Sub, the
Surviving Corporation and each of their affiliates (collectively, the "PRG
Group") against the unauthorized use or disclosure of any of their confidential
information presently known or hereinafter acquired by the Shareholder and
other good and valuable consideration, Shareholder hereby agrees that, subject
to adjustment pursuant to Section 12.5, for a period of five (5) years
following the Closing Date, Shareholder and his or her respective affiliates
shall not knowingly, directly or indirectly, for herself or himself or on or
behalf of any other corporation, person, firm, partnership, association or any
other entity (whether as an individual, agent, employee, officer, director or
in any other capacity)(other than through the provision of services by Practice
in accordance with the Service Agreement):

                 (a)      establish, operate or provide physician services at
any medical office, clinic or out-patient and/or ambulatory treatment or
diagnostic facility providing services similar to those provided by the
Practice or engage or participate in or finance any business which engages in
direct competition with the heathcare business being conducted by PRG, PRG Sub,
Surviving Corporation or any practice managed by PRG or any subsidiary of PRG
anywhere within 50 miles of any location of PRG, PRG Sub, Surviving Corporation
or any practice managed by PRG or any subsidiary of PRG; provided, however,
that this provision shall not prohibit the Shareholder or any of his or her
affiliates from purchasing or holding an aggregate equity interest of up to 2%,
so long as such Shareholder and his or her affiliates combined do not purchase
or hold an aggregate equity interest of more than 5%, in any business in direct
competition with the PRG, PRG Sub, Surviving Corporation or any practice
managed by PRG or any subsidiary of PRG; or

                 (b)      induce or attempt to influence any employee of PRG,
PRG Sub, Surviving Corporation or any practice managed by PRG or any subsidiary
of PRG to terminate his or her employment, or to hire any such employee,
whether or not so induced or influenced, except that any such employee may be
hired with PRG's prior written consent, which consent shall not be unreasonable
withheld.

         12.2    DAMAGES.

                 (a)      Because of the difficulty of measuring economic
losses to PRG, Surviving Corporation and PRG Sub as a result of the breach of
the foregoing covenant, and because of the immediate and irreparable damage
that would be caused to PRG, Surviving Corporation and PRG Sub for which it
would have no other adequate remedy, the Shareholder agrees that, in the event
of a breach by them of the foregoing covenant, the covenant may be enforced by
PRG, Surviving Corporation or PRG Sub by injunctions and restraining orders.
The foregoing right is in addition to the right to receive liquidated damages
set forth in subparagraph (b) below.

                 (b)      Because of the difficulty of measuring economic
losses as a result of a breach by Shareholder of the foregoing covenant,
Shareholder agrees that in the event of a breach of the foregoing covenant the
Shareholder shall be obligated to pay to PRG as liquidated damages an amount
set forth below opposite the year following Closing in which the breach occurs:

         PRG and PRG Sub agree that, prior to the imposition of the liquidated
damages set forth above, PRG or PRG Sub shall give the Shareholder notice of
the breach of Section 12.1 above and for a period of twenty (20) days from such
notice, the opportunity to cure such breach; provided, however, that PRG and
PRG Sub shall not be required to give such notice and opportunity to cure if
PRG or PRG Sub believes, in its reasonable discretion, that such breach was
willful.

         12.3    REASONABLE RESTRAINT.  It is agreed by the parties that the
foregoing covenants in this Section 12 impose a reasonable restraint on the
Shareholder in light of the activities and business of PRG and PRG Sub on the
date of the execution of this Agreement and the future plans of PRG and
Surviving Corporation.

         12.4    SEVERABILITY; REFORMATION.  The covenants in this Section 12
are severable and separate, and the unenforceability of any specific covenant
shall not affect the provisions of any other covenant.  Moreover, in the event
any court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention
of the parties that such restrictions be enforced to the fullest extent which
the court deems reasonable, and the Agreement shall thereby be reformed.

         12.5    TERM.  It is specifically agreed that the period of five (5)
years stated above, shall be computed by excluding from such computation any
time during which Shareholder is in violation of any provision of this Section
12.  The covenants contained in this Section 12 shall have no effect if the
transactions contemplated by this Agreement are not consummated for any reason
but otherwise shall not be affected by any breach of any other provision hereof
by any party hereto.


SECTION 13.      NONDISCLOSURE OF CONFIDENTIAL INFORMATION.  The Shareholder
recognizes and acknowledges that he had in the past, currently have, and in the
future may possibly have, access to certain confidential information of PRG,
Surviving Corporation or PRG Sub that is valuable, special and unique assets of
PRG's, Surviving Corporation's or PRG Sub's businesses.  The Shareholder agrees
that he will not disclose such confidential information to any person, firm,
corporation, association or other entity for any purpose or reason whatsoever,
unless (i) such information becomes available to or known by the public
generally through no fault of the Shareholder, (ii) disclosure is required by
law or the order of any governmental authority under color of law, provided,
that prior to disclosing any information pursuant to this clause (ii), the
Shareholder shall, if possible, give prior written notice thereof to the other
parties hereto, and provide such other parties hereto with the opportunity to
contest such disclosure, (iii) the Shareholder reasonably believes that such
disclosure is required in connection with the defense of a lawsuit against the
disclosing party, or (iv) the Shareholder is the sole and exclusive owner of
such confidential information as a result of the transactions contemplated
hereunder or otherwise.  In the event of a breach or threatened breach by the
Shareholder of the provisions of this Section 13, PRG, Surviving Corporation or
PRG Sub shall be entitled to an injunction restraining the Shareholder from
disclosing, in whole or in part, such confidential information.  Nothing herein
shall be construed as prohibiting PRG, Surviving Corporation or PRG Sub from
pursuing any other available remedy for such breach or threatened breach,
including the recovery of damages. The obligations of the parties under this
Section 13 shall survive the termination of this Agreement.


SECTION 14.      INVESTMENT REPRESENTATIONS. The Shareholder is able to bear
the economic risk of an investment in PRG common stock acquired pursuant to
this Agreement and can afford to sustain a total loss of such investment and
has such knowledge and experience in financial and business matters that he is
capable of evaluating the merits and risks of the proposed investment and
therefore has the capacity to protect his own interests in connection with the
acquisition of the PRG common stock.  The Shareholder or his respective
purchaser





                                       23

representatives have had an adequate opportunity to ask questions and receive
answers from the officers of PRG concerning any and all matters relating to the
background and experience of the officers and directors of PRG, the plans for
the operations of the business of PRG, and any plans for additional
acquisitions and the like.  The Shareholder or his respective purchaser
representatives have asked any and all questions in the nature described in the
preceding sentence and all questions have been answered to their satisfaction.

<PAGE>   29
liabilities may be deemed to have been incurred in the ordinary course of

consent of the other parties.  The parties to this Agreement shall cooperate
with respect to the form and content of any such disclosures.

         15.5    GOVERNING LAW.  THIS AGREEMENT SHALL BE INTERPRETED, CONSTRUED
AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS AND APPLIED
WITHOUT GIVING EFFECT TO ANY CONFLICTS OF LAWS PRINCIPLES.

         15.6    CAPTIONS. The captions or headings in this Agreement are made

describe, define or limit the scope or intent of the provisions of this
Agreement.

         15.7    INTEGRATION OF EXHIBITS.  All Exhibits attached to this
Agreement are integral parts of this Agreement as if fully set forth herein,
and all statements appearing therein shall be deemed disclosed for all purposes
and not only in connection with the specific representation in which they are

instrument

         15.10   BINDING EFFECT/ASSIGNMENT.  This Agreement shall be binding

lenders.

Agreement was initially prepared by PRG Sub, and that all parties have read and
negotiated the language used in this Agreement.  The parties agree that,
because all parties participated in negotiating and drafting this Agreement, no

hereunder, the prevailing party will be entitled to recover all reasonable
costs, including reasonable attorneys' fees, from the other party as part of
any judgment in such suit. The term "prevailing party" shall mean the party in
whose favor final judgment after appeal (if any) is rendered with respect to
the claims asserted in the Complaint.  "Reasonable attorneys' fees" are those
reasonable attorneys' fees actually incurred in obtaining a judgment in favor
of the prevailing party.

         15.13   AMENDMENTS; WAIVERS. This Agreement may be amended, modified
or supplemented only by an instrument in writing executed by all the parties
hereto.  Any waiver of the terms and conditions hereof must be in writing, and

any suit, action or proceeding arising out of this Agreement be instituted by
any party hereto (other than a suit, action or proceeding to enforce or realize
upon any final court judgment arising out of this Agreement), such suit, action
or proceeding shall be instituted only in a state or federal court in Dallas
County, Texas.  Each of the parties hereto consents to the in personam
jurisdiction of any state or federal court in Dallas County, Texas and waives
any objection to the venue of any such suit, action or proceeding.  The parties
hereto recognize that courts outside Dallas County, Texas may also have
jurisdiction over suits, actions or proceedings arising out of this Agreement,
and in the event that any party hereto shall institute a proceeding involving
this Agreement in a jurisdiction outside Dallas County, Texas, the party
instituting such proceeding shall indemnify any other party hereto for any
losses and expenses that may result from the breach of the foregoing covenant
to institute proceedings only in a state or federal court in Dallas County,
Texas.

found to be illegal, invalid or unenforceable under present or future laws,
such provision shall be fully severable and this Agreement shall be construed
and enforced as if such provision never comprised a part hereof; and the
remaining provisions hereof shall remain in full force and effect.  In lieu of
such provision, there shall be added automatically as part of this Agreement, a
provision as similar in its terms to such provision as may be possible and be
legal, valid and enforceable.
