         Pursuant to the Acquisition Agreements, the respective Acquisition

of the assets and properties, real and personal, tangible and intangible, and
certain liabilities of the Practices.

         The Acquisitions were consummated on August 30, 1996.

         As a result of the Acquisitions, the Company became the indirect
holder (through the respective Acquisition Subs) of, with certain limited
exceptions, all of the assets and properties, real and personal, tangible and
intangible, and certain liabilities of the Practices.  The respective
Acquisition Subs intend to provide the use of such assets to the respective
ophthalmological practices from which they were acquired pursuant to the terms
of the management services agreements entered into at the time of the
Acquisitions.
<PAGE>   3
         To the best knowledge of the Company, at the time of the Acquisitions
there was no material relationship between (i) the Practices and the
Physicians, on the one hand, and (ii) the Company, or any of its affiliates,
any director or officer of the Company, or any associate of such director or
officer on the other.

         The aggregate consideration paid by the Company as a result of the
Acquisitions was approximately 3,360,000 shares of the common stock, par value
$.01 per share, of the Company ("Common Stock") and approximately $210,000 cash,
of which (i) approximately 1,540,000 shares of Common Stock were issued in
connection with the Cincinnati Eye Acquisition, (ii) approximately 840,000
shares of Common Stock were issued, and approximately $210,000 was paid, in
connection with the Houston Eye Acquisition, (iii) approximately 510,000 shares
were issued in connection with the Henderson Acquisition, and (iv) approximately
470,000 shares were issued in connection with the Tampa Acquisition.  The
various acquisition considerations for such acquisitions were determined by
arms-length negotiations between the parties to the applicable acquisition
agreements.

         The primary source of funds used in the Acquisitions was cash from the
Company's working capital.

         The Company and various wholly-owned subsidiaries of the Company (each

personal, tangible and intangible, and certain liabilities of the Additional
Practices.

         The Additional Acquisitions were consummated on August 30, 1996.

         As a result of the Additional Acquisitions, the Company became the
indirect holder (through the respective Additional Acquisition Subs) of, with
certain limited exceptions, all of the assets and properties, real and
personal, tangible and intangible, and certain liabilities of the Additional
Practices.  The respective Additional Acquisition Subs intend to provide the
use of such assets to the respective ophthalmological practices from which they

on the one hand, and (ii) the Company, or any of its affiliates, any director
or officer of the Company, or any associate of such director or officer on the
other.

         The aggregate consideration paid by the Company as a result of the

Company common stock have been surrendered by Shareholders and replaced by
certificates representing PRG common stock, the certificates for Company common
stock shall, for all purposes, be deemed to evidence ownership of PRG common
stock.

                 (b)      The Shareholders shall deliver to PRG on the Closing

personal property used in operating the business of the Company or otherwise.
All such leases listed on Exhibit 2.7 are valid and enforceable in accordance

default by the Company, as lessor or lessee, or any condition or event of which
the Company or any Shareholder has knowledge which with notice or lapse of

not taken adequate steps to cure such default or to prevent a default from
occurring.

         2.8     CONDITION OF ASSETS.  All of the plants, structures and

the best knowledge of the Company and the Shareholders, may be used for their
intended purposes.  All of the inventory owned or used by the Company is in

         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, to the best knowledge of the
Company and Shareholders, 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").  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 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 the best
knowledge of the Company and the Shareholders, 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.

         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 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 pending or in
process or to the knowledge of the Company or Shareholders, threatened.  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.
Notwithstanding the foregoing, there shall be no breach by the Company or any
of the Shareholders of this Agreement for any disclosed pre- closing tax
liabilities.

         2.18    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,





                                       8
<PAGE>   10
and whether due or to become due, which is required to be reflected or reserved
on a non-footnoted balance sheet under GAAP or of any material liability or
obligation, other than those incurred in the ordinary course of business.  The
Company and the Shareholders do not know, or have reasonable grounds to know,
of any basis for the assertion against the Company as of the Balance Sheet
Date, of any claim or liability of any nature in any amount not fully reflected
or reserved against on the Balance Sheet which is required to be reflected or
reserved on a non-footnoted balance sheet under GAAP or any material claim. All
indebtedness of the Company (including without limitation, indebtedness for
borrowed money, guaranties and capital lease obligations) is described on
Exhibit 2.18 attached hereto.

         2.19    INSURANCE POLICIES.  The Company, each Shareholder and each
physician employee of the Company carries property, liability, malpractice,
workers' compensation and such other types of insurance as is customary in the
industry.  Valid 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 2.19 attached hereto and true and correct
copies have been delivered to PRG Sub.  Neither the Company nor any Shareholder
has received notice or other communication from the issuer of any such
insurance policy cancelling or amending such policy or threatening to do so.
Neither the Company, nor each Shareholder nor any physician employee of the
Company has any outstanding claims, settlements or premiums owed and past due
against any insurance policy.

         2.20    EMPLOYEE BENEFIT PLANS.  Except as set forth on Exhibit 2.20
attached hereto, the Company has neither established, nor maintains, nor is
obligated to make contributions to or under or otherwise participate in, (a)
any bonus or other type of compensation or employment plan, program, agreement,
policy, commitment, contract or arrangement (whether or not set forth in a
written document); (b) any pension, profit-sharing, retirement or other plan,
program or arrangement; or (c) any other employee benefit plan, fund or
program, including, but not limited to, those described in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA").  All
such plans listed on Exhibit 2.20 (individually "Company Plan," and
collectively "Company Plans") have been operated and administered in all
material respects in accordance with all applicable laws, rules and
regulations, including without limitation, ERISA, the Internal Revenue Code of
1986, as amended, Title VII of the Civil Rights Act of 1964, as amended, the
Equal Pay Act of 1967, as amended, the Age Discrimination in Employment Act of
1967, as amended, and the related rules and regulations adopted by those
federal agencies responsible for the administration of such laws.  No act or
failure to act by the Company has resulted in a "prohibited transaction" (as
defined in ERISA) with respect to the Company Plans.  No "reportable event" (as
defined in ERISA) has occurred with respect to any of the Company Plans.  The
Company has not previously made, is not currently making, and is not obligated
in any way to make, any contributions to any multiemployer plan within the
meaning of the Multi-Employer Pension Plan Amendments Act of 1980.  With
respect to each Company Plan, either (i) the value of plan assets (including
commitments under insurance contracts) is at least equal to the value of plan
liabilities or (ii) the value of plan liabilities in excess of plan assets is
disclosed on the Balance Sheet, all as of the Closing Date.

         2.21    COMPLIANCE WITH LAWS IN GENERAL.  The Company, the
Shareholders and Company's physician and licensed employees 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 Americans with Disabilities Act and any
environmental laws and medical waste laws, and there exist no violations by the
Company, any Shareholder or any physician or licensed employee of the Company
of any federal, state or local law or regulation.  Neither the Company nor any
Shareholder has received any notice of a violation of any federal, state and
local laws, regulations and ordinances relating to the operations of the
business and assets of the Company and no notice of any pending inspection or
violation of any such law, regulation or ordinance has been received by the
Company or any Shareholder.

         2.22    MEDICARE AND MEDICAID PROGRAMS.  The Company, each Shareholder
and each physician and licensed employee of the Company is qualified for
participation in the Medicare and Medicaid programs and is party to provider
agreements for such programs which are in full force and effect with no
defaults having occurred thereunder.  The Company, each Shareholder and each
physician and licensed employee of the Company has timely filed all claims or
other reports required to be filed with respect to the purchase of services by
third-party payors, and all such claims or reports are complete and accurate,
and has no liability to any payor with respect thereto.  There are no pending





                                       9
<PAGE>   11
appeals, overpayment determinations, adjustments, challenges, audit, litigation
or notices of intent to open Medicare or Medicaid claim determinations or other
reports required to be filed by the Company, each Shareholder and each licensed
employee of the Company. Neither the Company, nor any Shareholder, nor any
physician or licensed employee of the Company has been convicted of, or pled
guilty or nolo contendere to, patient abuse or negligence, or any other
Medicare or Medicaid program related offense and to the knowledge of the
Company and the Shareholders, none has committed any offense which may serve as
the basis for suspension or exclusion from the Medicare and Medicaid programs.

         2.23    FRAUD AND ABUSE.  The Company, the Shareholders and all
persons and entities providing professional services for the Company's business
have not, to the knowledge of the Company and the Shareholders, engaged in any

<PAGE>   23
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.

         11.4    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.

         11.5    LIMITATION ON INDEMNIFICATION.  Notwithstanding anything
contained herein to the contrary, any indemnification by the Company and
Shareholders in favor of PRG or PRG Sub shall not exceed in all cases the
Escrowed Shares, and such indemnification shall be limited to recourse against
the Escrowed Shares only, and any indemnification by PRG and PRG Sub in favor
of the Company and Shareholders shall not exceed in all cases $2,633,176.00.
Furthermore, no claim for Damages shall be made by any party more than one (1)
year after the Closing Date.  Notwithstanding the provisions hereof, the
Shareholder and the Company shall not be required to indemnify  PRG or PRG Sub
unless, and to the extent that, the aggregate amount of damages, losses,
liabilities, costs and other sums ("Damages") incurred by PRG and PRG Sub shall
exceed an amount equal to $526,635.22. Notwithstanding the provisions hereof,
PRG and PRG Sub shall not be required to indemnify the Company and the
Shareholder unless, and to the extent that, the aggregate amount of Damages
incurred by the Shareholder shall exceed an amount equal to $526,635.22.

         11.6    CERTAIN TAX MATTERS.  Shareholders shall within fifteen (15)
days after payment thereof and receipt of notice of such payment, reimburse,
indemnify and hold harmless PRG and Surviving Corporation for all undisclosed
taxes, and all related interest, penalties, and additions to tax ("Taxes") with
respect to full or partial taxable periods of the Company ending on or before
the Closing Date (other than income taxes).  For such purposes, the portion of
any Tax allocable to a partial taxable period ending on the Closing Date shall
be determined by apportioning the Tax for the entire taxable period based on
the number of days therein.


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





                                       22
<PAGE>   24
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 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 or the Company if the merger contemplated
hereby shall not have been consummated by August 31, 1996; or

         (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.


SECTION 13.      NONCOMPETITION.

         13.1    PROHIBITED ACTIVITIES.  In consideration of the amounts set
forth on Annex I hereto and 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, Corwin
and Smith, and other good and valuable consideration, each Shareholder, Corwin
and Smith  hereby agrees that, subject to adjustment pursuant to Section 13.5,
for a period of five (5) years following the Closing Date (provided, however,
that with respect to activities conducted in Kentucky, such period shall be
three hundred and sixty four days following the Closing Date), each
Shareholder, Corwin and Smith 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 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, Corwin or Smith or any of his or
her affiliates from purchasing or holding an aggregate equity interest of up to
2%, so long as such Shareholder, Corwin and Smith  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, other





                                       23
<PAGE>   25
than as set forth below, each Shareholder, Corwin and Smith agrees that, in the
event of a breach by such Shareholder, Corwin or Smith 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.
Notwithstanding the foregoing, in the event that Robert W. Nash, M.D. no longer
provides services to the Clinic within two years from the date hereof, PRG and
PRG Sub shall not be entitled to seek an injunction or restraining order
against Dr. Nash for the breach of Section 13.1 hereof;  provided, however,
that in the event Dr. Nash breaches Section 13.1 hereof at any time during the
two years or during the five years following the Closing Date, Section 13.2(b)
shall be applicable to such breach.

                 (b)      Because of the difficulty of measuring economic
losses as a result of a breach by a Shareholder, Corwin or Smith of the
foregoing covenant, such Shareholder, Corwin and Smith agrees to that in the
event of a breach of Section 13.1, the breaching Shareholder, Corwin or Smith
shall be obligated to pay to PRG as liquidated damages an amount set forth on
Exhibit 13.2.

         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, Corwin or Smith 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, Corwin or Smith  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 are not
consummated for any reason but otherwise shall not be affected by any breach of
any other provision hereof by any party hereto.   The covenants contained in
this Section 13 shall be of no further force and effect if the Service
Agreement is terminated pursuant to Section 9.3, 9.4(ii) or 10.6 thereof.

         13.6    PAYMENT OF OBLIGATION.   Subject to PRG's approval as set
forth below, each Shareholder, Smith and Corwin may satisfy his or her
obligation under Section 13.2(b) above by transferring to PRG or PRG Sub such
number of shares of PRG common stock owned by the Shareholder, Corwin or Smith
having an aggregate fair market value (based on the average of the last
reported sale price of PRG common stock on the NYSE or other exchange on which
PRG common stock is then listed or the last quoted ask price on any
over-the-counter market through which the PRG common stock is then quoted of
the ten business days ending three business days preceding the day on which the
Shareholder, Smith or Corwin transfers shares of PRG common stock to PRG
hereunder) equal to the obligation owing pursuant to Section 13.2; provided
that each of the following conditions are satisfied:

         (a)     The Shareholder, Corwin or Smith, as applicable,  shall
transfer to PRG or PRG Sub,  good, valid and marketable title to the shares of
PRG common stock, free and clear of all adverse claims, security interests,
liens, proxies, options, stockholder's agreements and encumbrances;

         (b)     The Shareholder, Corwin or Smith, as applicable,  shall make
such representations and warranties as to title to the stock, absences of
security interests, liens, claims, proxies, options, stockholder's agreements
and other encumbrances and other matters as reasonably requested by PRG or PRG
Sub; and

         (c)     The other terms and conditions of any transaction contemplated
pursuant to this Section and the effects thereof, including any legal or tax
consequences, shall be reasonably satisfactory to PRG and PRG Sub.

SECTION 14.      NONDISCLOSURE OF CONFIDENTIAL INFORMATION.  The Shareholders
recognize and acknowledge that they





                                       24
<PAGE>   26
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    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 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.

         15.2    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.

                                  WITNESSETH:

         WHEREAS, HEA PA operates an ophthalmology practice in Houston, Texas;

         WHEREAS, Shareholders are the only shareholders of the Company;

         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, immediately  prior to the Merger, HEA, Inc. ("HEA Inc.")
shall be the successor by merger to HEA PA; provided, that following such
merger, "Company" as used herein shall refer jointly and severally to HEA PA
and HEA Inc.;

         WHEREAS, it is intended that for federal income tax purposes the
Merger shall qualify as a reorganization within the meaning of Section
368(a)(1)(A), (a)(1)(B)  and (a)(2)(E) of the Internal Revenue Code of 1986, as
amended.

         NOW THEREFORE, in consideration of the mutual promises and covenants
hereinafter set forth, and for other good and valuable consideration, the

follows:

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 HEA INC.   On the Closing Date, PRG Sub
shall be merged with and into HEA Inc.  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.  HEA Inc. 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.

Shareholders' expense, affixed and cancelled.  The Shareholders agree to cure
any deficiencies with respect to the endorsement of the certificates or other
documents of conveyance with respect to such HEA Inc. common stock or with
respect to the stock powers accompanying any HEA Inc.  common stock.  Upon such
delivery, the Shareholders shall be entitled to receive in exchange therefor a
certificate representing that number of shares of PRG common stock and the
amount of any cash

about HEA PA as set forth on Exhibit 2.6 attached hereto, including the
unaudited Balance Sheet ("Balance Sheet") as of June 30, 1996 ("Balance Sheet
Date").  All such financial statements have been prepared in accordance with
generally accepted accounting principles consistently followed throughout the
periods indicated, and present fairly the financial position of HEA PA as of
such dates and the results of operations and cash flows for the period or
periods reflected therein (subject to normal year end adjustments and the
absence of notes for any unaudited Financial Statements), except as otherwise
indicated in the Financial Statements.  HEA Inc. has no financial information
as of the date hereof.

         2.7     LEASES.  Exhibit 2.7 attached hereto sets forth a list of all
leases pursuant to which the Company leases, as lessor or lessee, (i) real
property, or (ii) personal property involving rental payments within any
12-month period in excess of $5,000, used in operating the business of the
Company or otherwise.  All such leases listed on Exhibit 2.7 are valid and
enforceable in accordance with their respective terms, and there is not under
any such lease any existing default by the Company, as lessor or lessee, or any
condition or event of which the Company or any Shareholder has knowledge which
with notice or lapse of time, or both, would constitute a default, in respect
of which the Company has not taken adequate steps to cure such default or to
prevent a default from occurring, other than such defaults that would not,
individually or in the aggregate, result in a Material Adverse Effect.  For
purposes of this Agreement, the Company shall





                                       4
<PAGE>   10
be deemed to have "knowledge" of a particular fact or other matter if any
member of the Executive Committee of the Company, or any officer of the
Company, has actual conscious knowledge of the fact or other matter, and each
Shareholder shall be deemed to have "knowledge" of a particular fact or other
matter if such Shareholder has actual conscious knowledge of the fact or other
matter.

         2.8     CONDITION OF ASSETS.  All of the plants, structures and
equipment used by the Company in its business are in good condition and repair
in all material respects subject to normal wear and tear and conform, in all
material respects,  with all applicable ordinances, regulations and other laws,
and the Company and the Shareholders have no actual knowledge of any latent
defects therein.

         2.9     TITLE TO AND ENCUMBRANCES ON PROPERTY; ASC.  The Company does
not own any interest (other than leasehold interests referred to in Exhibit
2.7) in real property.  The leased real property referred to in Exhibit 2.7
constitutes the only real property necessary for the conduct of the Company's
business.  Except as set forth in Exhibit 2.9, the Company has good, valid and
marketable title to all the personal property owned by it ("Personal
Property").  The Personal Property and the leased personal property referred to
in Exhibit 2.7 constitute the only personal property necessary for the conduct
of the Company's business.  Except as set forth on Exhibit 2.7, upon
consummation of the transactions contemplated hereby, such leasehold interests
in real property and such Personal Property and leasehold interests in personal
property shall be free and clear of all liens, security interests, claims and
encumbrances.   HEA PA owns 21.5% of an outpatient surgery center that is
adjacent to its corporate headquarters and is majority owned and managed by
Columbia/HCA Healthcare.

         2.10    INVENTORIES.  All inventories of the Company used in the
conduct of its business are reflected on the Balance Sheet in accordance with
generally accepted accounting principles consistently applied.  The items of
the Company's inventory have been acquired in the ordinary course of its
business, are adequate for the reasonable requirements of its business, and, to
the best knowledge of the Company and the Shareholders, may be used for their
intended purposes.  All of the inventory owned or used by the Company is in
good, current, standard and merchantable condition and is not obsolete or
defective, other than as would not have a Material Adverse Effect.

         2.11    INTELLECTUAL PROPERTY RIGHTS; NAMES.  Except as set forth on
Exhibit 2.11, the Company has no right, title or interest in or to patents,
patent rights, corporate names, assumed names, manufacturing processes, trade

the only such items necessary for the conduct of its business. Set forth in
Exhibit 2.11 is a listing of all names of all predecessor companies of the
Company, including the names of any entities from whom the Company previously
acquired significant assets.  Except for off-the-shelf software licenses and
except as set forth on Exhibit 2.11, the Company is not a licensee in respect
of any patents, trademarks, service marks, trade names, copyrights or
applications therefor, or manufacturing processes, formulas or trade secrets or
similar items and no such licenses are necessary for the conduct of its
business.  To the best knowledge of the Company and Shareholders, no claim is
pending or has been made to the effect that the present or past operations of
the Company infringe upon or conflict with the asserted rights of others to any
patents, patent rights, manufacturing processes, trade names, trademarks,
service marks, inventions, licenses, specialized treatment protocols,
copyrights, formulas, know-how and trade secrets.  The Company has the sole and
exclusive right to use all such proprietary rights without infringing or
violating the rights of any third parties and no consents of any third parties
are required for the use thereof by the Surviving Corporation.

         2.12    DIRECTORS AND OFFICERS; PAYROLL INFORMATION; EMPLOYEES.  Set

compliance with all applicable laws, rules, regulations and ordinances
respecting employment and employment practices.  The Company has not engaged in
any unfair labor practice.  There are no unfair labor practices charges or
complaints pending or threatened against the Company, and the Company has never
been a party to any agreement with any union, labor organization or collective
bargaining unit.

         2.13    LEGAL PROCEEDINGS. Except as described in Exhibit 2.13 or
otherwise disclosed pursuant to this Section 2, there are no legal actions or
administrative proceedings or investigations instituted, or to the actual
knowledge of the Company or any Shareholder, threatened, against the Company or
affecting or that could affect the outstanding shares of the Company's stock,
any of the assets of the Company, or the operations, business, condition
(financial or otherwise) or results of operations of the Company which (i) if
successful, could, individually or in the aggregate, have a Material Adverse
Effect, or (ii) could adversely affect the ability of the Company or any
Shareholder to effect the transactions contemplated hereby.

         2.14    CONTRACTS.  With the exception of contracts or agreements that
involve either an unperformed commitment of less than $10,000 or that can be
terminated by the Company without liability within 30 days of the date hereof,
the Company has delivered to PRG Sub true copies of all written, and disclosed
to PRG Sub all oral, outstanding contracts, obligations and commitments of the
Company ("Contracts"), all of which are listed or incorporated by reference on
Exhibit 2.7 (in the case of leases), Exhibit 2.12 (in the case of employment
agreements) and Exhibit 2.14 (in the case of Contracts other than leases and
employment agreements) attached hereto.  Except as otherwise indicated on such
Exhibits, all of such Contracts are valid, binding and enforceable in
accordance with their terms and are in full force and effect, and no defenses,
offsets or counterclaims have been asserted or may be made by any party
thereto, except as may be limited by applicable bankruptcy, insolvency or
similar laws affecting creditors' rights generally or the availability of
equitable remedies.  Except as indicated on such Exhibits, there is not under
any such Contract any existing default by the Company, or any condition or
event of which the Company or any Shareholder has knowledge which with notice
or lapse of time, or both, would constitute a default, other than such defaults
which would not, individually or in the aggregate, result in a Material Adverse
Effect.   The Company and the Shareholders have no knowledge of any default by
any other party to such Contracts, other than such defaults which would not,
individually or in the aggregate, result in a Material Adverse Effect.  Neither
the Company nor the Shareholders have received written notice of the intention
of any party to any Contract to cancel or terminate any Contract, other than
terminations or cancellations that would not result in a Material Adverse
Effect. Other than those contracts, obligations and commitments of the Company
listed on Exhibit 2.7, Exhibit 2.12 and Exhibit 2.14, the Company is not a
party to any material written or oral agreement contract, lease or arrangement,

of the Company or to the assets of the Company.

         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 HEA
PA, of HEA PA's (i) accounts receivable, to the knowledge of the Company and
Shareholders, 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"). To the knowledge of the Company and Shareholders, Exhibit 2.16
contains a true and accurate statement of the working capital ("Working
Capital") of HEA PA as of the Balance Sheet Date.  HEA PA 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, HEA PA 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.  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.  Following Closing, the
administration of the collection of Accounts Receivable and the payment of
Accounts Payable shall be as set forth in Section 7.3(c) of the Service
Agreement.

         2.17    TAXES.  The Company has filed all tax returns (including tax
reports and other statements) required to be filed by it, and, except for such
items as the Company may be disputing in good faith and disclosed to PRG,  made
all payments of taxes (including any interest, penalty or addition thereto)
required to be made by it, on or before the date of this Agreement, with
respect to income taxes, real and personal property taxes, sales taxes, use
taxes, employment taxes, excise taxes and other taxes.  All such tax returns
are complete and accurate in all material  respects and properly reflect the
relevant taxes for the periods covered thereby.   The Company has paid all
taxes, penalties, assessments, and interest that have become due with respect
to any Tax Returns that it has filed, and the Company is not delinquent in the
payment of any tax, assessment or governmental charges, whether or not
reflected on the Tax Returns.  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
taxable 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.  Except as set forth on
Exhibit 2.17, 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    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
those incurred in the ordinary course of business, and other than liabilities
which would not, individually or in the aggregate, result in a Material Adverse
Effect.  The Company and the Shareholders do not know of any basis for the
assertion against the Company, as of the Balance Sheet Date, of any claim or
liability of any nature in any amount not fully reflected or reserved against
on the Balance Sheet, other than those incurred since that date in the ordinary
course of business or contemplated by this Agreement.  All indebtedness of the
Company (including without limitation, indebtedness for borrowed money,
guaranties and capital lease obligations) is described on Exhibit 2.18 attached
hereto.

         2.19    INSURANCE POLICIES.  The Company, each Shareholder and each
physician employee of the Company carries property, liability, malpractice,
workers' compensation and such other types of insurance pursuant to the
policies described on Exhibit 2.19, true and correct copies of which have been
delivered to PRG Sub.  Valid and enforceable policies of such types are
outstanding and duly in force and will remain duly in force through the Closing
Date.  Neither the Company nor any Shareholder has received notice or other
communication from the issuer of any such insurance policy cancelling or
amending such policy or threatening to do so.  Neither the Company, nor each
Shareholder nor any physician employee of the Company, has any outstanding
claims, settlements or premiums owed against any insurance policy.

         2.20    EMPLOYEE BENEFIT PLANS.  Except as set forth on Exhibit 2.20
attached hereto, the Company has neither established, nor maintains, nor is
obligated to make contributions to or under or otherwise participate in, (a)
any bonus or other type of compensation or employment plan, program, agreement,
policy, commitment, contract or arrangement (whether or not set forth in a
written document); (b) any pension, profit-sharing, retirement or other plan,
program or arrangement; or (c) any other employee benefit plan, fund or
program, including, but not limited to, those described in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA").  All
such plans listed on Exhibit 2.20 (individually "Company Plan," and
collectively "Company Plans") have been operated and administered in all
material respects in accordance with all applicable laws, rules and
regulations, including without limitation, ERISA, the Internal Revenue Code of
1986, as amended, Title VII of the Civil Rights Act of 1964, as amended, the
Equal Pay Act of 1967, as amended, the Age Discrimination in Employment Act of
1967, as amended, and the related rules and regulations adopted by those
federal agencies responsible for the administration of such laws.  No act or
failure to act by the Company has resulted in a "prohibited transaction" (as
defined in ERISA) with respect to the Company Plans.  No "reportable event" (as
defined in ERISA) has occurred with respect to any of the Company Plans.  The

RELATED PARTIES, in connection with (i) any material, waste or substance the
use, collection, handling, recycling, generation, treatment, storage, disposal,

authority, or the improper management or disposal of which may affect human
health or safety of the environment or (ii) the compliance by the Company, or

         11.4    INDEMNIFICATION PROCEDURE.  (a) As promptly as possible 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, but in any event at least ten (10) days prior to the due date
for any responsive pleadings, filings or other documents, 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.   In the event Indemnitor assumes the defense of such action or
proceeding, Indemnitor shall have full control thereof, including any
compromise or settlement.  Notwithstanding the foregoing, if the named parties
to any such action (including any impleaded parties) include both the
Indemnitor and Indemnified Person, and the Indemnified Person has been advised
by counsel that there may be one or more legal defenses available to it that
are different from or additional to those available to the Indemnitor, then the
Indemnified Person may employ separate counsel, reasonably acceptable to
Indemnitor, at the expense of the Indemnitor, and upon written notification
thereof, the Indemnitor shall not have the right to assume the defense of such
action on behalf of the Indemnified Person; provided, however, that the
Indemnitor shall not, in connection with any one such action or separate but
substantially similar or related actions in the same jurisdiction arising out
of the same general allegations or circumstances, be liable for the reasonable
fees and expenses of more than one separate firm of attorneys at any time for
the Indemnified Person, which firm shall be designated in writing by the
Indemnified Person.

         (b)     If the Indemnitor does not initially assume the defense of
such action or proceeding, then the Indemnified Person shall have the right of
defense thereof, at the sole cost and expense of the Indemnitor (if the
Indemnitor is entitled to indemnification hereunder); provided, however, that
the Indemnitor retains the right to assume the defense thereof at any time upon
delivery of written notice to the Indemnified Person.  If the Indemnified
Person defends an action or proceeding pursuant to this Section 11.4(b), the
Indemnified Person may not enter into, without the Indemnitor's consent, any
compromise or settlement thereof, which consent shall not be unreasonably
withheld.  Notwithstanding the foregoing, if the Indemnitor has delivered a
written notice to the Indemnified Person to the effect that the Indemnitor
disputes its potential liability to the Indemnified Person under this Section
11 and if such dispute is resolved in favor of the Indemnitor, the Indemnitor
shall not be required to bear the costs and expenses of the Indemnified
Person's defense pursuant to this Section or of the Indemnitor's participation
therein at the Indemnified Person's request, and the Indemnified Person shall
reimburse the Indemnitor in full for all costs and expenses of such matter. The
Indemnitor may participate in, but not control, any defense or settlement
controlled by the Indemnified Person pursuant to this Section 11.4, and the
Indemnitor shall bear its own costs and expenses with respect to such
participation; provided, however, that if the named parties to any such action
(including any impleaded parties) include





                                       21
<PAGE>   27
both the Indemnitor and the Indemnified Person, and the Indemnitor has been
advised by counsel that there may be one or more legal defenses available to it
that are different from or additional to those available to the Indemnified
Person, then the Indemnitor may employ separate counsel, reasonably acceptable
to Indemnified Person, and upon written notification thereof, the Indemnified
Person shall not have the right to assume the defense of such action on behalf
of the Indemnitor.

         11.5    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.  Shareholders 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 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.  PRG agrees not to take any position with
respect to the Tax Returns that is inconsistent with the position taken by the
Company in prior periods.

                 (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"). Shareholders 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 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, 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.

                 (d)      The Company and the Shareholders shall have the right
to review and approve (such approval not to be unreasonably withheld) any Tax
Returns prepared by PRG or PRG Sub in accordance with this Section 11.5 to the
extent such returns relate to taxes arising on or prior to the Closing Date.

         11.6    INDEMNIFICATION LIMITATIONS. Notwithstanding the provisions of
Section 11, (i) no parties shall be required to indemnify another party with
respect to a breach of a representation, warranty or covenant, unless the claim
for indemnification is brought within the time limits set forth in Section 11.1
hereof, (ii) the Shareholder on the one hand, and PRG and PRG Sub on the other
hand, shall not be required to indemnify PRG and PRG Sub, on the one hand, and
the Shareholders and the Company, on the other hand, with respect to a breach
of a representation, warranty or covenant, unless and to the extent that, the
aggregate amount of damages incurred by the Shareholders, on the one hand, or
PRG Sub and PRG, on the other hand, shall exceed $200,000.  In no event shall
the Company or the Shareholders, with respect to indemnification owed by the
Company to PRG or PRG Sub, be required to indemnify PRG or PRG Sub in an amount
exceeding, in the aggregate, $20,000,000.00; provided, however, that the
indemnification owing by any Shareholder (and not the Company) to PRG or PRG
Sub shall not exceed, in the aggregate, the Merger Consideration received by
such Shareholder in connection with the transactions evidenced hereby and set
forth on Annex I; provided, however, notwithstanding anything contained herein,
the limitations set forth above for indemnification obligations shall not be
applicable to any Shareholder who commits malpractice or causes a breach of
Section 2.23 giving rise to an indemnification obligation in excess of
$20,000,000.  In no event shall PRG or PRG Sub be required to indemnify the
Company or the Shareholders in an amount exceeding, in the aggregate,
$20,000,000.00.

         11.7    TAX BENEFITS; INSURANCE PROCEEDS.   The total amount of any
indemnity payments owed by one party to another party to this Agreement shall
be reduced by any correlative tax benefit received by the party to be
indemnified or the net proceeds received by the party to be indemnified with
respect to recovery from third parties or insurance proceeds, and such
correlative insurance benefit shall be net of the insurance premium, if any,
that becomes due as a result of such claims.

         11.8    PAYMENT OF INDEMNIFICATION OBLIGATION.   In the event any
Shareholder has an indemnification obligation to any Indemnified Person
hereunder, subject to the Indemnified Person's approval as set forth below,
such Shareholder may satisfy such obligation by transferring to such
Indemnified Person such number of shares of PRG common stock owned by the
Shareholder having an aggregate fair market value (based on the last reported
sale price of PRG common stock on the NYSE or other exchange on which PRG
common stock is then listed or the last quoted ask price on any
over-the-counter market through which the PRG common stock is then quoted on
the last trading day immediately preceding the day on which the Shareholder
transfers shares of PRG common stock to such Indemnified Person hereunder)
equal to the indemnification obligation; provided that each of the following
conditions are satisfied:

         (a)     The Shareholder shall transfer to such Indemnified Person
good, valid and marketable title to the shares of PRG common stock, free and
clear of all adverse claims, security interests, liens, proxies, options,
stockholder's agreements and encumbrances;

         (b)     The Shareholder shall make such representations and warranties
as to title to the stock, absences of security interests, liens, claims,
proxies, options, stockholder's agreements and other encumbrances and other
matters as reasonably requested by such Indemnified Person; and

         (c)     The other terms and conditions of any transaction contemplated
pursuant to this Section and the effects thereof, including any legal or tax
consequences, shall be reasonably satisfactory to such Indemnified Person.


SECTION 12.      TERMINATION; REMEDIES.

         12.1    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
respect or if the Company or any Shareholders fails to comply in any 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; provided,
however, this shall not apply to any such misrepresentation, noncompliance or
breach that would not, individually or in the aggregate, result in a Material
Adverse Effect; provided that termination of this Agreement shall be PRG's and
PRG Sub's sole remedy prior to the Closing Date with respect to any such
misrepresentation, noncompliance or breach;

         (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 respect or
if PRG or PRG Sub fails to comply in any respect with any covenant or agreement
contained herein and such misrepresentation, noncompliance or breach is not
cured, waived or eliminated within twenty (20) days after receipt of written
notice thereof; provided, however, this shall not apply to such
misrepresentation, noncompliance or breach that would not, individually or in
the aggregate, result in a Material Adverse Effect; provided that termination
of this Agreement shall be the Company's or the Shareholders' sole remedy prior
to the Closing Date with respect to any such misrepresentation, noncompliance
or breach;

         (d)     by PRG, PRG Sub, the Company or the Shareholders if the merger
contemplated hereby shall not have been consummated by August 31, 1996;
provided, further, that if the failure to consummate by such date is the result
of a party's breach of or noncompliance with this Agreement, then such party
shall not be entitled to terminate this Agreement pursuant to this Section
12.1(d); or





                                       23
<PAGE>   29
         (e)     by PRG at any time prior to August 22, 1996 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.

         (f)     by PRG, PRG Sub, the Company or any Shareholder if any court
of competent jurisdiction in the United States of America or other (federal or
state) governmental body shall have issued an order, decree or ruling, or taken
any other action restraining, enjoining or otherwise prohibiting the Merger and
such order, decree, ruling or other action shall have become final and
non-appealable.

         12.2    EXCLUSIVE RIGHTS AND REMEDIES.  The remedies of PRG, PRG Sub,
the Company and each Shareholder under Section 11 of this Agreement shall be
each respective party's sole and exclusive remedies.

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 ophthalmological
physician services at any medical office, clinic or out-patient and/or
ambulatory treatment or diagnostic facility or other healthcare 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 by PRG, PRG Sub, Surviving Corporation or any
practice managed by PRG or any subsidiary of PRG at the time of the Closing, in
either case, anywhere within 25 miles of any location of PRG, PRG Sub,
Surviving Corporation or any practice managed by PRG or any subsidiary of PRG
at the time of Closing that is located in a Standard Statistical Metropolitan
Area having a population of 1,000,000 or more or within 50 miles of any other
location of PRG, PRG Sub, Surviving Corporation or any practice managed by PRG
or any subsidiary of PRG at the time of Closing;  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 in any entity of up to
2%, so long as such Shareholder and his or her affiliates 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 unreasonably
withheld.

         Notwithstanding the foregoing, the investments or activities set forth
in Section 6.2(f) of the Service Agreement or on Exhibit 13.1, hereof shall not
be deemed to be a breach hereof.  Provided, further that this Section 13 shall
be of no further force and effect if the Service Agreement is terminated
pursuant to Section 3.11 or 9.3 thereof.

         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





                                       24
<PAGE>   30
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, times the pro rata amount of the Merger Consideration being
received by such Shareholder in connection with the transactions contemplated
hereby and as set forth on Annex I.

</TABLE>

         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 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.      CONFIDENTIAL INFORMATION.

         14.1    NONDISCLOSURE BY SHAREHOLDERS.     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 a valuable, special and unique asset of PRG's,
Surviving Corporation's or PRG Sub's businesses.  Each Shareholder agrees that

corporation, association or other entity for any purpose or reason whatsoever,

generally through no fault of such Shareholder, (ii) disclosure is required by
law or the order of any governmental authority under color of law, provided,

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, (iv) the Shareholder is the sole and exclusive owner of such
confidential information as a result of the transactions contemplated hereunder

that the source of such information was not bound to a confidentiality
agreement with PRG or PRG Sub or otherwise prohibited from transmitting such
information to the Shareholder by a contractual, legal or fiduciary obligation
of which PRG or PRG Sub had actual conscious knowledge, or (vii) such
information becomes available to such Shareholder on a non-confidential basis
from a source other than PRG or PRG Sub, provided that such source is not bound
by a confidentiality agreement with PRG or PRG Sub or otherwise prohibited from
transmitting such information to the Shareholder by any contractual, legal or
fiduciary obligation of which the Shareholder had actual conscious knowledge.
In the event of a breach or threatened breach by the





                                       25
<PAGE>   31
Shareholders of the provisions of this Section 14.1, 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 14.1 shall survive the termination of this Agreement.

         14.2    NONDISCLOSURE BY PRG OR PRG SUB.     PRG and PRG Sub recognize
and acknowledge that they had in the past, currently have, and in the future
may possibly have, access to certain confidential information of the Company or
the Shareholders that is a valuable, special and unique asset of the Company's
business.  PRG and PRG Sub 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 PRG or PRG Sub, (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), PRG and PRG Sub 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) PRG or PRG Sub reasonably
believes that such disclosure is required in connection with the defense of a
lawsuit against the disclosing party, (iv) PRG or PRG Sub is the sole and
exclusive owner of such confidential information as a result of the
transactions contemplated hereunder or otherwise, (v) such information was in
the possession of PRG or PRG Sub on a non-confidential basis prior to its
disclosure by the Company or the Shareholder, provided that the source of such
information was not bound to a confidentiality agreement with the Company or
the Shareholders or otherwise prohibited from transmitting such information to
PRG or PRG Sub by a contractual, legal or fiduciary obligation of which the
Shareholder had actual conscious knowledge, or (vi) such information becomes
available to PRG or PRG Sub on a non-confidential basis from a source other
than the Company or the Shareholders that is not bound by a confidentiality
agreement with the Company or the Shareholders or otherwise prohibited from
transmitting such information to PRG or PRG Sub by any contractual, legal or
fiduciary obligation of which PRG or PRG Sub had actual conscious knowledge.
In the event of a breach or threatened breach by PRG or PRG Sub of the
provisions of this Section 14.2, the Company or any Shareholder shall be
entitled to an injunction restraining PRG or PRG Sub from disclosing, in whole
or in part, such confidential information.  Nothing herein shall be construed
as prohibiting the Company or the Shareholders 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 14.2 shall
survive the termination of this Agreement.

SECTION 15.      INVESTMENT REPRESENTATIONS.     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 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.

         16.5    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.

         16.6    CAPTIONS. The captions or headings in this Agreement are made
for convenience and general reference only and shall not be construed to
describe, define or limit the scope or intent of the provisions of this
Agreement.

         16.7    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
explicitly referenced.

         16.8    ENTIRE AGREEMENT/AMENDMENT.   THIS INSTRUMENT, INCLUDING ALL
EXHIBITS ATTACHED HERETO, CONTAINS THE ENTIRE AGREEMENT OF THE PARTIES AND
SUPERSEDES ANY AND ALL PRIOR OR CONTEMPORANEOUS AGREEMENTS BETWEEN THE PARTIES,
WRITTEN OR ORAL, WITH RESPECT TO THE TRANSACTIONS CONTEMPLATED HEREBY.

         16.9    COUNTERPARTS.  This Agreement may be executed in several
counterparts, each of which when so executed shall be deemed to be an original,
and such counterparts shall together constitute and be one and the same
instrument

         16.10   BINDING EFFECT/ASSIGNMENT.  This Agreement shall be binding
on, and shall inure to the benefit of, the parties hereto, and their respective
successors and assigns, and no other person shall acquire or have any right
under or by virtue of this Agreement.  No party may assign any right or
obligation hereunder without the prior written consent of the other parties;
provided, however, that PRG Sub, Surviving Corporation and PRG may, after the
Closing Date, assign its rights and obligations hereunder to an affiliate, and
prior to the Closing Date, PRG Sub may assign its rights and obligations to
another wholly owned subsidiary of PRG.

         16.11   NO RULE OF CONSTRUCTION.  The parties acknowledge that this
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

drafting this Agreement.

         16.12   COSTS OF ENFORCEMENT. In the event that PRG Sub, Surviving
Corporation or PRG, on the one hand, or the Company or the Shareholders, on the
other hand, file suit in any court against any other party to enforce the terms
of this Agreement against the other party or to obtain performance by it
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.

         16.13   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
signed by the parties hereto.  The waiver of any of the terms and conditions of
this Agreement shall not be construed as a waiver of any other terms and
conditions hereof.

         16.14   CHOICE OF FORUM.  Each of the parties hereto agree that should
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 or Harris County, Texas.  Each of the parties hereto consents to
the in personam jurisdiction of any state or federal court in Dallas County,
Texas or Harris 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 or Harris 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 or Harris County, Texas, the party
instituting such proceeding shall indemnify any other party hereto for





                                       28
<PAGE>   34
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 or Harris County, Texas.

         16.15   SERVICE OF PROCESS.  Service of any and all process that may
be served on any party hereto in any suit, action or proceeding arising out of
this Agreement may be made in the manner and to the address set forth in
Section 16.1 and service thus made shall be taken and held to be valid personal
service upon such party by any party hereto on whose behalf such service is
made.

         16.16   SEVERABILITY.  If any provision of this Agreement shall be
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.

         16.17   AFFILIATE OF THE COMPANY.  The parties hereto agree and
acknowledge that the landlord under the Building Lease is not an affiliate of
the Company for purposes of this Agreement.

         16.18   POST-CLOSING MATTER; DISPOSAL OF ASSETS BY PRG.   After the
Closing Date, PRG and PRG Sub shall not and shall not permit any of its
affiliates to dispose of a significant part of the assets of the Company within
the two years following the Closing Date except (a) in the ordinary course of
business, or (ii) to affiliates of PRG or PRG Sub, or (iii) to eliminate
duplicate services or excess capacity.

         16.19   ARBITRATION AND MEDIATION.   The parties agree to utilize the
following procedure with regard to any contention or claim arising out of or
relating to this Agreement or any breach thereof (a "Dispute").  If any Dispute
cannot be settled through direct discussions, the parties hereto agree to
endeavor first to resolve the Dispute through mediation in accordance with
Section 16.19(a).  If the Dispute cannot be resolved through such mediation,
the parties hereto agree to resolve such Dispute by arbitration in accordance
with Section 16.19(b).

         (a)     MEDIATION.

                 (i)      INITIATION OF PROCEDURE.  The initiating party shall
         give written notice to the other parties, describing the nature of the
         Dispute and its claim for relief and identifying one or more of the
         individuals with authority to resolve the Dispute on such parties'
         behalf.  The other parties shall have five (5) business days from
         receipt of such notice within which to designate in writing one or
         more individuals with authority to resolve the Dispute on each such
         party's behalf.

                 (ii)     SELECTION OF MEDIATOR.  Within ten (10) business days
         from the date of designation by the non- initiating party, the parties
         shall make a good faith effort to select a person to mediate the
         Dispute.  If no mediator has been selected under this procedure, the
         parties shall jointly request a State or Federal District Judge of
         their choosing (or if they cannot agree, the President of the Dallas
         Bar Association) to supply within ten (10) business days a list of
         potential qualified attorney-mediators in Dallas, Texas.  Within five
         (5) business days of receipt of the list, the parties shall rank the
         proposed mediators in numerical order of preference, simultaneously
         exchange such list and select as the mediator the individual receiving
         the highest combined ranking.  If such mediator is not available to
         serve, they shall proceed to contact the mediator who was next highest
         in ranking until they select a mediator.

                 (iii)    TIME AND PLACE FOR MEDIATION; PARTIES REPRESENTED.
         In consultation with the mediator selected, the parties shall promptly
         designate a mutually convenient time in Dallas, Texas for the
         mediation, such time to be no later than sixty (60) days after
         selection of the mediator.  In the mediation, each party shall be
         represented by persons with authority and discretion to negotiate a
         resolution of the Dispute, and may be represented by counsel.

                 (iv)     CONDUCT OF MEDIATION.  The mediator shall determine
         the format for the meetings and the mediation sessions shall be in
         private.  The mediator will keep confidential all information learned
         in private caucus with any party unless specifically authorized by
         such party to make disclosure of the information to the





                                       29
<PAGE>   35
         other party.  The parties agree that the mediation shall be governed
         by the provisions of Chapter 154 of the Tex. Civ. Pract. & Rem. Code
         and such other rules as the mediator shall reasonably prescribe.

                 (v)      FEES OF MEDIATOR; DISQUALIFICATION.  The fees and
         expenses of the mediator shall be borne by the prevailing party.  The
         mediator shall be disqualified as a witness, consultant, expert or
         counsel for any party with respect to the Dispute and any related
         matters.

                 (vi)     CONFIDENTIALITY.  Mediation is a compromise
         negotiation for purposes of federal and state Rules of Evidence and
         constitutes privileged communications under Texas law.  The entire
         mediation process is confidential, and such conduct, statement,
         promises, offers, views and opinions shall not be discoverable or
         admissible in any proceeding for any purpose.

         (b)     ARBITRATION.

                 (i)      Following the close of any unsuccessful mediation
         proceeding with respect to a Dispute, such Dispute shall, at the
         written request of any party, be determined and settled pursuant to
         arbitration in Dallas, Texas, by three arbitrators, one to be
         appointed by the Shareholders, and one by PRG, and a neutral
         arbitrator to be appointed by such two-party arbitrators.  The neutral
         arbitrator shall be an attorney and shall act as chairman.  Should (x)
         any party fail to appoint an arbitrator as hereinabove contemplated
         within ten (10) days after the party not requesting arbitration has
         received such written request, or (y) the two arbitrators appointed by
         or on behalf of the parties as contemplated in this Section 16.19(b)
         fail to appoint a neutral arbitrator as hereinabove contemplated
         within ten days after the date of appointment of the last arbitrator
         appointed by or on behalf of the parties, then any person sitting as
         Judge of the United States District Court for the Northern District of
         Texas, Dallas, Division, upon application of the Shareholders or PRG,
         shall appoint such arbitrator to fill such position with the same
         force and effect as though such arbitrator had been appointed as
         hereinabove contemplated.

                 (ii)     The arbitration proceeding shall be conducted in
         accordance with the Commercial Arbitration Rules of the American
         Arbitration Association.  A determination, award, or other action
         shall be considered the valid action of the arbitrators if supported
         by the affirmative vote of two or three of the three arbitrators.  The
         costs of arbitration (exclusive of attending the arbitration, and of
         the fees and expenses of legal counsel to such party, all of which
         shall be borne by such party) shall be borne by the prevailing party.
         The arbitration award shall be final and conclusive and shall receive
         recognition, and judgment upon such award may be entered and enforced
         in any court of competent jurisdiction.

                 (iii)    For purposes of this Section 16.19(b), the act of
         Shareholders who are receiving a majority of the PRG common stock
         being issued hereunder shall constitute the act of the Shareholders.
         Upon the written request of any party initiating the applicability of
         this Section 16.19(b), the parties shall discuss in good faith for a
         period of five (5) days after the delivery of such request, whether to
         adopt additional or different arbitration rules, different arbitrators
         or a different venue than those set forth above.  In the event that
         the parties do not agree to any such changes within such ten-day
         period, then the arbitration provisions of this Section 16.19(b) shall
         be followed without amendment or further delay.

affecting creditors' rights generally or the availability of equitable
remedies.  The execution and delivery of this Agreement, and the agreements

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.

and any indemnification by PRG and PRG Sub in favor of Seller shall not exceed

<PAGE>   21
         (b)     at any time by PRG or PRG Sub if any representation or
warranty of Seller contained in this Agreement or in any certificate or other
document executed and delivered by Seller pursuant to this Agreement is or
becomes untrue or breached in any material respect or if Seller 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 Seller 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 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

         (d)     by PRG, PRG Sub or by Seller if the merger contemplated hereby
shall not have been consummated by August 31, 1996; or

         (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 Seller, that such termination is desirable and in

SECTION 11.      [INTENTIONALLY LEFT BLANK].



SECTION 12.      NONDISCLOSURE OF CONFIDENTIAL INFORMATION.  Seller recognizes
and acknowledges that it had in the past, currently have, and in the future may
possibly have, access to certain confidential information of PRG or PRG Sub
that is valuable, special and unique assets of PRG's or PRG Sub's businesses.
Seller agrees that it 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 Seller, (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), Seller
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) Seller reasonably believes that such disclosure is
required in connection with the defense of a lawsuit against the disclosing
party, or (iv) Seller 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 Seller of the
provisions of this Section 12, PRG or PRG Sub shall be entitled to an
injunction restraining Seller and from disclosing, in whole or in part, such
confidential information.  Nothing herein shall be construed as prohibiting PRG
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 12 shall survive the termination of this Agreement.


SECTION 13.      INVESTMENT REPRESENTATIONS.

         13.1    ECONOMIC RISK; SOPHISTICATION.  Seller 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 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.  Seller or its 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.  Seller or its purchaser representatives has asked
any and all questions in the nature described in the preceding sentence and all
questions have been answered to their satisfaction.

                         GREGORY L. HENDERSON, M.D.,

                              PRG IV ACQ. CORP.,

                          AGREEMENT AND PLAN OF MERGER


         This AGREEMENT AND PLAN OF MERGER, made and executed as of the 13th
day of August, 1996, is by and among PRG IV ACQ. CORP., a Delaware corporation
("PRG Sub"); PHYSICIANS RESOURCE GROUP, INC., a Delaware corporation ("PRG");
GREGORY L. HENDERSON, M.D., P.A., a Florida professional association (the
Company"), and  GREGORY L. HENDERSON, M.D.,  an individual resident of the
State of Florida (the "Shareholder").





                                  WITNESSETH:

         WHEREAS, the Company operates an ophthalmology practice in Brandon, 
Florida;

         WHEREAS, Shareholders are the only shareholders of the Company;

         WHEREAS, PRG Sub is engaged in the business of acquiring the assets of
and operating 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"), and for
financial accounting purposes 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 Sub with and into the Company shall occur on the
31st day of August, 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 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 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 Florida 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 Florida Business Corporation Law.





                                       1
<PAGE>   3
         1.2     MERGER CERTIFICATES.  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 shall cause to be properly executed and filed on the Closing
Date Articles of Merger meeting the requirements of the Florida Business
Corporation Law.  The Merger shall become effective on the Closing Date.

         1.3     CERTIFICATE OF INCORPORATION OF SURVIVING CORPORATION.
Effective on the Closing Date, the Certificate of Incorporation of PRG Sub
shall be the Articles of Incorporation of the Surviving Corporation and to the
extent the foregoing is not permitted by law, the Articles of Incorporation of
the Surviving Corporation shall be the Articles of Incorporation of the Company
and shall immediately be amended to contain the terms and provisions of the
Articles of Incorporation of PRG Sub.

         1.4     BYLAWS OF THE SURVIVING CORPORATION.  The Bylaws of PRG Sub on
the Closing Date shall be the Bylaws of the Surviving Corporation, until duly
amended in accordance with their terms.

         1.5     DIRECTORS OF THE SURVIVING CORPORATION.  The persons who are
directors of PRG Sub immediately prior to the Closing Date shall, from and
after the Closing Date, be the directors of the Surviving Corporation until
their successors have been duly elected or appointed and qualified or until
their earlier death, resignation or removal in accordance with the Surviving
Corporation's Articles or Certificate of Incorporation and Bylaws.

         1.6     OFFICERS OF THE SURVIVING CORPORATION.  The persons who are
officers of PRG Sub immediately prior to the Closing Date shall, from and after
the Closing Date, be the officers of the Surviving Corporation and shall hold
their same respective office(s) until their earlier death, resignation or
removal.

         1.7     CONVERSION OF COMPANY COMMON STOCK.  The manner of converting
shares of the Company 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 shares of Company common stock issued and
outstanding 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 fully registered 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 shares of the Company shall cease to be outstanding
and shall be cancelled and retired and shall cease to exist, and each holder of
a certificate representing any such shares of Company common stock shall
thereafter cease to have any rights with respect to such shares of Company
common stock, except the right to receive, without interest, the Merger
Consideration.

                 (b)      Each share of Company common stock held in the
Company's treasury, if any, on the Closing Date, by virtue of the Merger, shall
cease to be outstanding and shall be cancelled and retired without payment of
any consideration therefor and shall cease to exist.

                 (c)      On the Closing Date, each share of PRG Sub common
stock issued and outstanding as of the Closing Date shall be surrendered in
exchange for a share of validly issued, fully paid and nonassessable share of
common stock of Surviving Corporation.

         1.8     EXCHANGE OF CERTIFICATES REPRESENTING SHARES OF COMPANY COMMON
STOCK.

                 (a)      At or after the Closing Date, (i) the Shareholders,
as the holders of all outstanding certificates representing shares of Company
common stock, shall, upon surrender of such certificates, be entitled to
receive the Merger Consideration and (ii) until the certificates representing
Company common stock have been surrendered by Shareholders and replaced by
certificates representing PRG common stock, the certificates for Company common
stock shall, for all purposes, be deemed to evidence ownership of PRG common
stock.

<PAGE>   4
                 (b)      The Shareholders shall deliver to PRG on the Closing
Date the certificates representing Company common stock owned by them, duly
endorsed in blank by the Shareholders, or accompanied by blank stock powers and
with all necessary transfer tax and other revenue stamps, acquired at the
Shareholders' expense, affixed and cancelled.  The Shareholders agree to cure
any deficiencies with respect to the endorsement of the certificates or other
documents of conveyance with respect to such Company common stock or with
respect to the stock powers accompanying any Company Common Stock.  Upon such
delivery, the Shareholder shall be entitled to receive in exchange therefor a
certificate representing that number of shares of PRG common stock Shareholder
is entitled to receive pursuant to Section 1.7.

                 (c)      Notwithstanding Section 1.7 or any other provision of
this Section 1.8, no fractional shares of PRG common stock will be issued.

         1.9     ESCROW.  In addition to the shares issuable to the
Shareholders at Closing, PRG shall deposit in escrow the number of shares of
PRG Common Stock set forth on Annex I (the "Escrowed Shares") pursuant to the
terms of an Escrow Agreement (the "Escrow Agreement") in the form attached
hereto as Exhibit 1.9, to be entered into among Shareholders, the Company, PRG
Sub, PRG and Jackson &Walker, L.L.P. , 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 Sub may be entitled to indemnification
pursuant to Article XI in accordance with the terms of the Escrow Agreement.

         1.10    SUBSEQUENT ACTIONS. If, at any time after the Closing Date,
the Surviving Corporation 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
Corporation its right, title or interest in, to or under any of the rights,
properties or assets of the Company or PRG Sub acquired or to be acquired by

hereby represent and warrant to PRG Sub and PRG as follows:

         2.1     CORPORATE EXISTENCE; GOOD STANDING.  The Company is a

outstanding shares of capital stock free of all security interests, claims,
encumbrances and liens in the amounts set forth on Exhibit 2.1.  The
Shareholders have owned the equity interests set forth on Exhibit 2.1 since

nonassessable.  No shares of capital stock of the Company are owned by the
Company in treasury. The Company has not acquired any treasury shares since

other obligations the holders of which have the right to vote with the
stockholders of the Company on any matter, (b) securities of the Company
convertible into equity interests in the Company, or (c) commitments,

options, rights or warrants to issue any such equity interests in the Company,
to issue securities of the Company convertible into such equity interests, or
to redeem any securities of the Company. No shares of capital stock of the
Company have been issued or disposed of in violation of the preemptive rights,
rights of first refusal or similar rights of any of the Company's stockholders.
The Company is not required to qualify to do business as a foreign corporation

         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 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
pending or in process, or to the knowledge of the Company and Shareholders,
threatened.  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    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,





                                       8
<PAGE>   10
and whether due or to become due, other than those incurred in the ordinary
course of business.  The Company and the Shareholders do not know, or have
reasonable grounds to know, of any basis for the assertion against the Company
as of the Balance Sheet Date, of any claim or liability of any nature in any
amount not fully reflected or reserved against on the Balance Sheet, or of any
claim or liability of any nature arising since that date other than those
incurred in the ordinary course of business or contemplated by this Agreement.
All indebtedness of the Company (including without limitation, indebtedness for
borrowed money, guaranties and capital lease obligations) is described on
Exhibit 2.18 attached hereto.

         2.19    INSURANCE POLICIES.  The Company, each Shareholder and each
physician employee of the Company carries property, liability, malpractice,
workers' compensation and such other types of insurance as is customary in the
industry.  Valid 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 2.19 attached hereto and true and correct
copies have been delivered to PRG Sub.  Neither the Company nor any Shareholder
has received notice or other communication from the issuer of any such
insurance policy cancelling or amending such policy or threatening to do so.
Neither the Company, nor each Shareholder nor any physician employee of the
Company has any outstanding claims, settlements or premiums owed against any
insurance policy.

         2.20    EMPLOYEE BENEFIT PLANS.  Except as set forth on Exhibit 2.20
attached hereto, the Company has neither established, nor maintains, nor is
obligated to make contributions to or under or otherwise participate in, (a)
any bonus or other type of compensation or employment plan, program, agreement,
policy, commitment, contract or arrangement (whether or not set forth in a
written document); (b) any pension, profit-sharing, retirement or other plan,
program or arrangement; or (c) any other employee benefit plan, fund or
program, including, but not limited to, those described in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA").  All
such plans listed on Exhibit 2.20 (individually "Company Plan," and
collectively "Company Plans") have been operated and administered in all
material respects in accordance with all applicable laws, rules and
regulations, including without limitation, ERISA, the Internal Revenue Code of
1986, as amended, Title VII of the Civil Rights Act of 1964, as amended, the
Equal Pay Act of 1967, as amended, the Age Discrimination in Employment Act of
1967, as amended, and the related rules and regulations adopted by those
federal agencies responsible for the administration of such laws.  No act or
failure to act by the Company has resulted in a "prohibited transaction" (as
defined in ERISA) with respect to the Company Plans.  No "reportable event" (as
defined in ERISA) has occurred with respect to any of the Company Plans.  The
Company has not previously made, is not currently making, and is not obligated
in any way to make, any contributions to any multiemployer plan within the
meaning of the Multi-Employer Pension Plan Amendments Act of 1980.  With
respect to each Company Plan, either (i) the value of plan assets (including
commitments under insurance contracts) is at least equal to the value of plan
liabilities or (ii) the value of plan liabilities in excess of plan assets is
disclosed on the Balance Sheet, all as of the Closing Date.

         2.21    ADVERSE AGREEMENTS.  The Company is not, and will not be as of
the Closing Date, a party to any agreement or instrument or subject to any
charter or other corporate 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 Company.

         2.22    COMPLIANCE WITH LAWS IN GENERAL.  The Company, the
Shareholders and Company's physician and licensed employees 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 Americans with Disabilities Act and any
environmental laws and medical waste laws, and there exist no violations by the
Company, any Shareholder or any physician or licensed employee of the Company
of any federal, state or local law or regulation.  Neither the Company nor any
Shareholder has received any notice of a violation of any federal, state and
local laws, regulations and ordinances relating to the operations of the
business and assets of the Company and no notice of any pending inspection or
violation of any such law, regulation or ordinance has been received by the
Company or any Shareholder.

         2.23    MEDICARE AND MEDICAID PROGRAMS.  The Company, each Shareholder

which are in full force and effect with no defaults having occurred thereunder.
The Company, each Shareholder and each physician and licensed employee of the
Company has timely filed all claims or other reports required to be filed with
respect to the purchase of services by third-party payors, and all such claims
or reports are complete and accurate, and has no liability to any payor with
respect thereto.  There are no pending appeals, overpayment determinations,
adjustments, challenges, audit, litigation or notices of intent to open
Medicare or Medicaid claim determinations or other reports required to be filed
by the Company, each Shareholder and each licensed employee of the Company.
Neither the Company, nor any Shareholder, nor any physician or licensed
employee of the Company has been convicted of, or pled guilty or nolo
contendere to, patient abuse or negligence, or any other Medicare or Medicaid
program related offense and none has committed any offense which may serve as
the basis for suspension or exclusion from the Medicare and Medicaid programs.

         2.24    FRAUD AND ABUSE.  The Company, the Shareholders and all
persons and entities providing professional services for the Company's business
have not, to the knowledge of the Company and the Shareholders, engaged in any

<PAGE>   24
OR THE OTHER DOCUMENTS TO BE EXECUTED IN CONNECTION HEREWITH, OR.

         (VIII)  ANY ACCRUED UNFUNDED RETIREMENT OR PENSION PLAN LIABILITIES.

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

EXTENT THAT IT IS FINALLY JUDICIALLY DETERMINED THAT SUCH INDEMNIFIED PERSON IS
NOT ENTITLED TO INDEMNIFICATION HEREUNDER.

         11.4    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.

         11.5    LIMITATION ON INDEMNIFICATION.  Notwithstanding anything
contained herein to the contrary, any indemnification by the Company and
Shareholders in favor of PRG or PRG Sub shall not exceed in all cases the
Escrowed Shares, and any indemnification by PRG and PRG Sub in favor of the
Company and Shareholders shall not exceed in all cases the Escrowed Shares.
Furthermore, no claim for Damages shall be made by any party more than one (1)
year after the Closing Date.

         11.6    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
Corporation covering taxable periods ending on or before the Closing Date which
have not been filed on or before the Closing Date.  Shareholders 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 Corporation for all taxes (excluding, however, income taxes of the
Company and the tax liabilities, if any, disclosed on the Financial
Statements), 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"). Shareholders 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 Corporation for all Taxes for any Straddle





                                       23
<PAGE>   25
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, 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.

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

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

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 on Schedule 13.2.

         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 are not consummated for any
reason but otherwise shall not be affected by any breach of any other provision
hereof by any party hereto.  The covenants contained in this Section 13 shall
terminate in the event the Service Agreement is terminated pursuant to Section
3.11 or Section 9.3 thereto.

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    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.

         16.9    COUNTERPARTS.  This Agreement may be executed in several
counterparts, each of which when so executed shall be deemed to be an original,
and such counterparts shall together constitute and be one and the same
instrument

         16.10   BINDING EFFECT/ASSIGNMENT.  This Agreement shall be binding
on, and shall inure to the benefit of, the parties hereto, and their respective
successors and assigns, and no other person shall acquire or have any right

rights and obligations hereunder to an affiliate and to their lender or
lenders.

         16.11   NO RULE OF CONSTRUCTION.  The parties acknowledge that this
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

language in favor of or against any party by reason of that party's role in
drafting this Agreement.

         16.12   COSTS OF ENFORCEMENT. In the event that PRG Sub, Surviving
Corporation or PRG, on the one hand, or the Company or the Shareholders, on the
other hand, file suit in any court against any other party to enforce the terms
of this Agreement against the other party or to obtain performance by it
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.

         16.13   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
signed by the parties hereto.  The waiver of any of the terms and conditions of
this Agreement shall not be construed as a waiver of any other terms and
conditions hereof.

         16.14   CHOICE OF FORUM.  Each of the parties hereto agree that should
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.

         16.15   SERVICE OF PROCESS.  Service of any and all process that may
be served on any party hereto in any suit, action or proceeding arising out of
this Agreement may be made in the manner and to the address set forth in
Section 16.1 and service thus made shall be taken and held to be valid personal
service upon such party by any party hereto on whose behalf such service is
made.

         16.16   SEVERABILITY.  If any provision of this Agreement shall be
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.

         16.17   ARBITRATION.  Except for matters for which an injunction,
restraining order, writ of mandamus, specific





                                       28

performance or other equitable relief may be sought by a party hereunder, any
disputes between the parties arising out of or otherwise relating to this
Agreement (whether based in contract, tort, or other legal theory), shall be
resolved by and through an arbitration proceeding to be conducted under the
auspices of the American Arbitration Association (or any like organization
successor thereto) in Dallas, Texas.  Such arbitration proceeding shall be
conducted in as expedited a manner as is then permitted by the commercial
arbitration rules (formal or informal) of the American Arbitration Association,
and the arbitrator or arbitrators in any such arbitration shall be persons who
are expert in the subject matter of the dispute.  Both the foregoing agreement
of the parties to arbitrate any and all such claims, and the results,
determination, finding, judgment and/or award rendered through such
Arbitration, shall be final and binding on the parties hereto and may be
specifically enforced by legal proceedings, and the parties agree that a
judgment of any court of competent jurisdiction may be rendered upon any
arbitration rendered pursuant to this Section.  Such arbitration may be
initiated by written notice from any party to the others which shall be a
compulsory and binding proceeding on each party.  The arbitration shall be
conducted before a panel of arbitrators selected in accordance with the rules
of the American Arbitration Association.  The costs of the arbitrators and the
arbitration, including the cost of their respective attorneys, witnesses and
experts in connection with such arbitration, incurred by the prevailing party
in the arbitration shall be paid by the other parties thereto.  Time is of the
essence of this arbitration procedure, and the arbitrators shall be instructed
and required to render their decision within ten (10) days following completion
of the arbitration.  Any and all legal proceedings to enforce this Agreement
(including any action to compel arbitration hereunder or to enforce any award
or judgment rendered thereby) shall be governed in accordance with this
Section.

         16.18   GOOD FAITH.  The parties agree to act in good faith and
reasonably with respect to the exercise of their respective rights, duties and
obligations .

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 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
pending or in process, or to the knowledge of the Company and Shareholders,
threatened.  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    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,





                                       8
<PAGE>   10
and whether due or to become due, other than those incurred in the ordinary
course of business.  The Company and the Shareholders do not know, or have
reasonable grounds to know, of any basis for the assertion against the Company
as of the Balance Sheet Date, of any claim or liability of any nature in any
amount not fully reflected or reserved against on the Balance Sheet, or of any
claim or liability of any nature arising since that date other than those
incurred in the ordinary course of business or contemplated by this Agreement.
All indebtedness of the Company (including without limitation, indebtedness for
borrowed money, guaranties and capital lease obligations) is described on
Exhibit 2.18 attached hereto.

         2.19    INSURANCE POLICIES.  The Company, each Shareholder and each
physician employee of the Company carries property, liability, malpractice,
workers' compensation and such other types of insurance as is customary in the
industry.  Valid 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 2.19 attached hereto and true and correct
copies have been delivered to PRG Sub.  Neither the Company nor any Shareholder
has received notice or other communication from the issuer of any such
insurance policy cancelling or amending such policy or threatening to do so.
Neither the Company, nor each Shareholder nor any physician employee of the
Company has any outstanding claims, settlements or premiums owed against any
insurance policy.

         2.20    EMPLOYEE BENEFIT PLANS.  Except as set forth on Exhibit 2.20
attached hereto, the Company has neither established, nor maintains, nor is
obligated to make contributions to or under or otherwise participate in, (a)
any bonus or other type of compensation or employment plan, program, agreement,
policy, commitment, contract or arrangement (whether or not set forth in a
written document); (b) any pension, profit-sharing, retirement or other plan,
program or arrangement; or (c) any other employee benefit plan, fund or
program, including, but not limited to, those described in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA").  All
such plans listed on Exhibit 2.20 (individually "Company Plan," and
collectively "Company Plans") have been operated and administered in all
material respects in accordance with all applicable laws, rules and
regulations, including without limitation, ERISA, the Internal Revenue Code of
1986, as amended, Title VII of the Civil Rights Act of 1964, as amended, the
Equal Pay Act of 1967, as amended, the Age Discrimination in Employment Act of
1967, as amended, and the related rules and regulations adopted by those
federal agencies responsible for the administration of such laws.  No act or
failure to act by the Company has resulted in a "prohibited transaction" (as
defined in ERISA) with respect to the Company Plans.  No "reportable event" (as
defined in ERISA) has occurred with respect to any of the Company Plans.  The
Company has not previously made, is not currently making, and is not obligated
in any way to make, any contributions to any multiemployer plan within the
meaning of the Multi-Employer Pension Plan Amendments Act of 1980.  With
respect to each Company Plan, either (i) the value of plan assets (including
commitments under insurance contracts) is at least equal to the value of plan
liabilities or (ii) the value of plan liabilities in excess of plan assets is
disclosed on the Balance Sheet, all as of the Closing Date.

         2.21    ADVERSE AGREEMENTS.  The Company is not, and will not be as of
the Closing Date, a party to any agreement or instrument or subject to any
charter or other corporate 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 Company.

         2.22    COMPLIANCE WITH LAWS IN GENERAL.  The Company, the
Shareholders and Company's physician and licensed employees 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 Americans with Disabilities Act and any
environmental laws and medical waste laws, and there exist no violations by the
Company, any Shareholder or any physician or licensed employee of the Company
of any federal, state or local law or regulation.  Neither the Company nor any

business and assets of the Company and no notice of any pending inspection or
violation of any such law, regulation or ordinance has been received by the
Company or any Shareholder.

         (VII)   ANY LIABILITY OF THE COMPANY OR THE SHAREHOLDERS FOR COSTS AND

OR THE OTHER DOCUMENTS TO BE EXECUTED IN CONNECTION HEREWITH, OR.

         (VIII)  ANY ACCRUED UNFUNDED RETIREMENT OR PENSION PLAN LIABILITIES.

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.

         11.4    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.

         11.5    LIMITATION ON INDEMNIFICATION.  Notwithstanding anything
contained herein to the contrary, any indemnification by the Company and
Shareholders in favor of PRG or PRG Sub shall not exceed in all cases the
Escrowed Shares, and any indemnification by PRG and PRG Sub in favor of the
Company and Shareholders shall not exceed in all cases the Escrowed Shares.
Furthermore, no claim for Damages shall be made by any party more than one (1)
year after the Closing Date.

         11.6    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
Corporation covering taxable periods ending on or before the Closing Date which
have not been filed on or before the Closing Date.  Shareholders 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 Corporation for all taxes (excluding, however, income taxes of the
Company and the tax liabilities, if any, disclosed on the Financial
Statements), 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"). Shareholders 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 Corporation for all Taxes for any Straddle





                                       23
<PAGE>   25
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, 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 August 31, 1996; or

         (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.


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):





                                       24
<PAGE>   26
                 (a)      except as set forth on Exhibit 13.1(a),  attached
hereto, 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 by PRG, PRG Sub, Surviving Corporation or any
practice managed by PRG or any subsidiary of PRG anywhere within, as of the
Closing Date, (i) 25 miles of any location of the Clinic, the practices set
forth on Exhibit 13.1(a), and any ophthalmology practice managed by PRG or any
subsidiary of PRG located outside of a Standard Statistical Metropolitan Area
having a population of greater than 1,000,000, or (ii) 10 miles of any location
of any ophthalmology practice managed by PRG or any subsidiary of PRG located
within a Standard Statistical Metropolitan Area having a population of greater
than 1,000,000; provided, however, that this provision shall not prohibit (a)
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) a Shareholder from performing surgery at any hospital or outpatient
surgical facility which provides services similar to those provided by the
Clinic, PRG or any of its Affiliates; 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 on Schedule 13.2.

         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 are not consummated for any
reason but otherwise shall not be affected by any breach of any other provision
hereof by any party hereto.  The covenants contained in this Section 13 shall
terminate in the event the Service Agreement is terminated pursuant to Section
3.11 or Section 9.3 thereto.

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    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.

on, and shall inure to the benefit of, the parties hereto, and their respective
successors and assigns, and no other person shall acquire or have any right

of this Agreement against the other party or to obtain performance by it
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.

         16.13   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

this Agreement shall not be construed as a waiver of any other terms and
conditions hereof.

         16.14   CHOICE OF FORUM.  Each of the parties hereto agree that should
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.

         16.15   SERVICE OF PROCESS.  Service of any and all process that may
be served on any party hereto in any suit, action or proceeding arising out of
this Agreement may be made in the manner and to the address set forth in
Section 16.1 and service thus made shall be taken and held to be valid personal
service upon such party by any party hereto on whose behalf such service is
made.

         16.16   SEVERABILITY.  If any provision of this Agreement shall be
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.

         16.17   ARBITRATION.  Except for matters for which an injunction,
restraining order, writ of mandamus, specific





                                       28

performance or other equitable relief may be sought by a party hereunder, any
disputes between the parties arising out of or otherwise relating to this
Agreement (whether based in contract, tort, or other legal theory), shall be
resolved by and through an arbitration proceeding to be conducted under the
auspices of the American Arbitration Association (or any like organization
successor thereto) in Dallas, Texas.  Such arbitration proceeding shall be
conducted in as expedited a manner as is then permitted by the commercial
arbitration rules (formal or informal) of the American Arbitration Association,
and the arbitrator or arbitrators in any such arbitration shall be persons who
are expert in the subject matter of the dispute.  Both the foregoing agreement
of the parties to arbitrate any and all such claims, and the results,
determination, finding, judgment and/or award rendered through such
Arbitration, shall be final and binding on the parties hereto and may be
specifically enforced by legal proceedings, and the parties agree that a
judgment of any court of competent jurisdiction may be rendered upon any
arbitration rendered pursuant to this Section.  Such arbitration may be
initiated by written notice from any party to the others which shall be a
compulsory and binding proceeding on each party.  The arbitration shall be
conducted before a panel of arbitrators selected in accordance with the rules
of the American Arbitration Association.  The costs of the arbitrators and the
arbitration, including the cost of their respective attorneys, witnesses and
experts in connection with such arbitration, incurred by the prevailing party
in the arbitration shall be paid by the other parties thereto.  Time is of the
essence of this arbitration procedure, and the arbitrators shall be instructed
and required to render their decision within ten (10) days following completion
of the arbitration.  Any and all legal proceedings to enforce this Agreement
(including any action to compel arbitration hereunder or to enforce any award
or judgment rendered thereby) shall be governed in accordance with this
Section.

         16.18   GOOD FAITH.  The parties agree to act in good faith and
reasonably with respect to the exercise of their respective rights, duties and
obligations .

         WHEREAS, Shareholders are the only shareholders of the Company;

         WHEREAS, PRG Sub is engaged in the business of acquiring the assets of

and

         WHEREAS, the Boards of Directors of each of the Company, PRG and PRG

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;

         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:

subject to the terms and conditions herein stated.

         1.1     MERGER OF PRG SUB INTO THE COMPANY.  On the Closing Date, PRG

Effective on the Closing Date, the Certificate of Incorporation of PRG Sub
shall be the Articles of Incorporation of the Surviving Corporation and to the
extent the foregoing is not permitted by law, the Articles of Incorporation of

Articles of Incorporation of PRG Sub.

         1.4     BYLAWS OF THE SURVIVING CORPORATION.  The Bylaws of PRG Sub on
the Closing Date shall be the Bylaws of the Surviving Corporation, until duly
amended in accordance with their terms.

         1.5     DIRECTORS OF THE SURVIVING CORPORATION.  The persons who are

shares of the Company in the Merger shall be as follows:

                 (a)      As a result of the Merger and without any action on

action on the part of the holder thereof, be converted into the right to
receive the number of fully registered shares of PRG common stock set forth on

Consideration").  As a result of the Merger and without any action on the part
of the holder thereof, all shares of the Company shall cease to be outstanding

a certificate representing any such shares of Company common stock shall
thereafter cease to have any rights with respect to such shares of Company
common stock, except the right to receive, without interest, the Merger
Consideration.

                 (b)      Each share of Company common stock held in the
Company's treasury, if any, on the Closing Date, by virtue of the Merger, shall
cease to be outstanding and shall be cancelled and retired without payment of
any consideration therefor and shall cease to exist.

                 (c)      On the Closing Date, each share of PRG Sub common
stock issued and outstanding as of the Closing Date shall be surrendered in
exchange for a share of validly issued, fully paid and nonassessable share of
common stock of Surviving Corporation.

         1.8     EXCHANGE OF CERTIFICATES REPRESENTING SHARES OF COMPANY COMMON
STOCK.

                 (a)      At or after the Closing Date, (i) the Shareholders,
as the holders of all outstanding certificates representing shares of Company
common stock, shall, upon surrender of such certificates, be entitled to
receive the Merger Consideration and (ii) until the certificates representing
Company common stock have been surrendered by Shareholders and replaced by
certificates representing PRG common stock, the certificates for Company common
stock shall, for all purposes, be deemed to evidence ownership of PRG common
stock.

with all necessary transfer tax and other revenue stamps, acquired at the
Shareholders' expense, affixed and cancelled.  The Shareholders agree to cure
any deficiencies with respect to the endorsement of the certificates or other
documents of conveyance with respect to such Company common stock or with

delivery, the Shareholder shall be entitled to receive in exchange therefor a
certificate representing that number of shares of PRG common stock Shareholder
is entitled to receive pursuant to Section 1.7.

Sub, PRG and Jackson &Walker, L.L.P. , 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 Sub may be entitled to indemnification
pursuant to Article XI in accordance with the terms of the Escrow Agreement.

         1.10    SUBSEQUENT ACTIONS. If, at any time after the Closing Date,
the Surviving Corporation 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
Corporation its right, title or interest in, to or under any of the rights,

SECTION 2.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY AND THE
SHAREHOLDERS.

         The Company and the Shareholders, jointly (with respect to

severally (with respect to representations and warranties by such Shareholder),
hereby represent and warrant to PRG Sub and PRG as follows:

         2.1     CORPORATE EXISTENCE; GOOD STANDING.  The Company is a
professional association duly organized, validly existing and in good standing
under the laws of the State of Florida.  The Company has all necessary
corporate powers to own all of its assets and to carry on its business as such
business is now being conducted.  The Company does not own stock in or control,
directly or indirectly, any other corporation, association or business
organization, nor is the Company a party to any joint venture or partnership.
The shareholders are the sole shareholders of the Company and own all
outstanding shares of capital stock free of all security interests, claims,

Company common stock has been legally and validly issued and fully paid and
nonassessable.  No shares of capital stock of the Company are owned by the
Company in treasury. The Company has not acquired any treasury shares since
January 1, 1994.  There are no outstanding (a) bonds, debentures, notes or
other obligations the holders of which have the right to vote with the
stockholders of the Company on any matter, (b) securities of the Company
convertible into equity interests in the Company, or (c) commitments,





                                       3
<PAGE>   5
options, rights or warrants to issue any such equity interests in the Company,
to issue securities of the Company convertible into such equity interests, or
to redeem any securities of the Company. No shares of capital stock of the
Company have been issued or disposed of in violation of the preemptive rights,
rights of first refusal or similar rights of any of the Company's stockholders.
The Company is not required to qualify to do business as a foreign corporation
in any other state or jurisdiction by reason of its business, properties or
activities in or relating to such other state or jurisdiction.  The Company
does not have any assets, employees or offices in any state other than Florida.

         The Company has not been a division or subsidiary of PRG or any of its
subsidiaries since January 1, 1994.  The Company and each Shareholder do not
own any stock of PRG.

         2.2     POWER AND AUTHORITY FOR TRANSACTIONS.  The Company has the
corporate power to execute, deliver and perform this Agreement and all
agreements and other documents executed and delivered by it pursuant to this
Agreement or to be executed and delivered on the Closing Date, and has taken
all action required by law, its Articles of Incorporation, its Bylaws or
otherwise, to authorize the execution, delivery and performance of this
Agreement and such related documents.  Each Shareholder has the legal capacity
to enter into and perform this Agreement and the other agreements to be

approval of its stockholders necessary to the consummation of the transactions
contemplated herein.  This Agreement and all agreements and documents executed

Date, duly executed and delivered by the Company and the Shareholders, as
appropriate, and constitute or will constitute the legal, valid and binding
obligations of the Company and the Shareholders, enforceable against the
Company and the Shareholders in accordance with their respective terms, except
as may be limited by applicable bankruptcy, insolvency or similar laws
affecting creditors' rights generally or the availability of equitable
remedies.  The execution and delivery of this Agreement, and the agreements
executed and delivered pursuant to this Agreement or to be executed and
delivered on the Closing Date, do not, and, subject to the receipt of consents
described on Exhibit 2.5, the consummation of the actions contemplated hereby
will not, violate any provision of the Articles of Incorporation or Bylaws of
the Company or any provisions of, or result in the acceleration of, any
obligation under any mortgage, lien, lease, agreement, rent, instrument, order,
arbitration award, judgment or decree to which the Company or any Shareholder
is a party or by which the Company or any Shareholder is bound, or violate any
material restrictions of any kind to which the Company is subject, or result in
any lien or encumbrance on any of the Company's assets.

         2.3     PERMITS, LICENSES AND GOVERNMENTAL AUTHORIZATIONS.  All
building or other permits, certificates of occupancy, concessions, grants,
franchises, licenses, certificates of need and other governmental
authorizations and approvals required to be maintained by the Company, the
Shareholders and each physician or licensed employee of the Company have been
duly obtained and are in full force and effect and are described on Exhibit
2.3.  There are no proceedings pending or, to the knowledge of the Company and
the Shareholders, threatened, which may result in the revocation, cancellation
or suspension, or any adverse modification, of any thereof.

         2.4     CORPORATE RECORDS.  True and correct copies of the Articles of
Incorporation, Bylaws and minutes of the Company and all amendments thereto of
the Company have been delivered to PRG Sub.  The minute books of the Company
contain all accurate minutes of the meetings of and consents to actions taken
without meetings of the Board of Directors and stockholders of the Company
since its formation.

         2.5     CONSENTS.  Except as set forth on Exhibit 2.5, no consent,

lender, lessor, any manufacturer or supplier or any other person or entity is
required to authorize, or is required in connection with, the execution,

leases pursuant to which the Company leases, as lessor or lessee, real or
personal property used in operating the business of the Company or otherwise.
All such leases listed on Exhibit 2.7 are valid and enforceable in accordance
with their respective terms, and there is not under any such lease any existing
material default by the Company, as lessor or lessee, or any condition or event
of which the Company or any Shareholder has knowledge which with notice or
lapse of time, or both, would constitute a material default, in respect of
which the Company has not taken adequate steps to cure such default or to
prevent a default from occurring.

         2.8     CONDITION OF ASSETS.  All of the plants, structures and
equipment used by the Company in its business are in good condition and repair
subject to normal wear and tear and conform with all applicable ordinances,

business, are adequate for the reasonable requirements of its business, and, to
the best knowledge of the Company and the Shareholders, may be used for their
intended purposes.  All of the inventory owned or used by the Company is in

claim is pending or has been made to the effect that the present or past
operations of the Company infringe upon or conflict with the asserted rights of
others to any patents, patent rights, manufacturing processes, trade names,
trademarks, service marks, inventions, licenses, specialized treatment
protocols, copyrights, formulas, know-how and trade secrets.  The Company has
the sole and exclusive right to use all such proprietary rights without

not engaged in any unfair labor practice.  There are no unfair labor practices
charges or complaints pending or threatened against the Company, and the
Company has never been a party to any agreement with any union, labor

         2.13    LEGAL PROCEEDINGS.  Neither the Company nor any Shareholder
nor outstanding shares of the Company's stock nor any of the Company's assets
is subject to any pending, nor does the Company or any Shareholder have

condemnation or other proceeding against or relating to or affecting the
Company, any Shareholder, the outstanding shares of the Company's stock, any of
the assets of the Company, the operations, business or prospects of the Company
or the transactions contemplated by this Agreement, and, to the knowledge of
the Company and the Shareholders, no basis for any such action exists, nor is

would constitute a default.   The Company and the Shareholders have no
knowledge of any default by any other party to such Contracts.  Neither the
Company nor the Shareholders have received notice of the intention of any party

of the Company or to the assets of the Company.

         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 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
pending or in process, or to the knowledge of the Company and Shareholders,
threatened.  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    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,





                                       8
<PAGE>   10
and whether due or to become due, other than those incurred in the ordinary
course of business.  The Company and the Shareholders do not know, or have
reasonable grounds to know, of any basis for the assertion against the Company
as of the Balance Sheet Date, of any claim or liability of any nature in any
amount not fully reflected or reserved against on the Balance Sheet, or of any
claim or liability of any nature arising since that date other than those
incurred in the ordinary course of business or contemplated by this Agreement.
All indebtedness of the Company (including without limitation, indebtedness for
borrowed money, guaranties and capital lease obligations) is described on
Exhibit 2.18 attached hereto.

         2.19    INSURANCE POLICIES.  The Company, each Shareholder and each
physician employee of the Company carries property, liability, malpractice,
workers' compensation and such other types of insurance as is customary in the
industry.  Valid 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 2.19 attached hereto and true and correct
copies have been delivered to PRG Sub.  Neither the Company nor any Shareholder
has received notice or other communication from the issuer of any such
insurance policy cancelling or amending such policy or threatening to do so.
Neither the Company, nor each Shareholder nor any physician employee of the
Company has any outstanding claims, settlements or premiums owed against any
insurance policy.

         2.20    EMPLOYEE BENEFIT PLANS.  Except as set forth on Exhibit 2.20
attached hereto, the Company has neither established, nor maintains, nor is
obligated to make contributions to or under or otherwise participate in, (a)
any bonus or other type of compensation or employment plan, program, agreement,
policy, commitment, contract or arrangement (whether or not set forth in a
written document); (b) any pension, profit-sharing, retirement or other plan,
program or arrangement; or (c) any other employee benefit plan, fund or
program, including, but not limited to, those described in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA").  All
such plans listed on Exhibit 2.20 (individually "Company Plan," and
collectively "Company Plans") have been operated and administered in all
material respects in accordance with all applicable laws, rules and
regulations, including without limitation, ERISA, the Internal Revenue Code of
1986, as amended, Title VII of the Civil Rights Act of 1964, as amended, the
Equal Pay Act of 1967, as amended, the Age Discrimination in Employment Act of
1967, as amended, and the related rules and regulations adopted by those
federal agencies responsible for the administration of such laws.  No act or
failure to act by the Company has resulted in a "prohibited transaction" (as
defined in ERISA) with respect to the Company Plans.  No "reportable event" (as
defined in ERISA) has occurred with respect to any of the Company Plans.  The
Company has not previously made, is not currently making, and is not obligated
in any way to make, any contributions to any multiemployer plan within the
meaning of the Multi-Employer Pension Plan Amendments Act of 1980.  With
respect to each Company Plan, either (i) the value of plan assets (including
commitments under insurance contracts) is at least equal to the value of plan
liabilities or (ii) the value of plan liabilities in excess of plan assets is
disclosed on the Balance Sheet, all as of the Closing Date.

         2.21    ADVERSE AGREEMENTS.  The Company is not, and will not be as of
the Closing Date, a party to any agreement or instrument or subject to any
charter or other corporate 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 Company.

         2.22    COMPLIANCE WITH LAWS IN GENERAL.  The Company, the
Shareholders and Company's physician and licensed employees 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 Americans with Disabilities Act and any
environmental laws and medical waste laws, and there exist no violations by the
Company, any Shareholder or any physician or licensed employee of the Company
of any federal, state or local law or regulation.  Neither the Company nor any
Shareholder has received any notice of a violation of any federal, state and
local laws, regulations and ordinances relating to the operations of the
business and assets of the Company and no notice of any pending inspection or
violation of any such law, regulation or ordinance has been received by the
Company or any Shareholder.

         2.23    MEDICARE AND MEDICAID PROGRAMS.  The Company, each Shareholder
and each physician and

which are in full force and effect with no defaults having occurred thereunder.
The Company, each Shareholder and each physician and licensed employee of the
Company has timely filed all claims or other reports required to be filed with
respect to the purchase of services by third-party payors, and all such claims
or reports are complete and accurate, and has no liability to any payor with
respect thereto.  There are no pending appeals, overpayment determinations,
adjustments, challenges, audit, litigation or notices of intent to open
Medicare or Medicaid claim determinations or other reports required to be filed
by the Company, each Shareholder and each licensed employee of the Company.
Neither the Company, nor any Shareholder, nor any physician or licensed
employee of the Company has been convicted of, or pled guilty or nolo
contendere to, patient abuse or negligence, or any other Medicare or Medicaid
program related offense and none has committed any offense which may serve as
the basis for suspension or exclusion from the Medicare and Medicaid programs.

         2.24    FRAUD AND ABUSE.  The Company, the Shareholders and all
persons and entities providing professional services for the Company's business
have not, to the knowledge of the Company and the Shareholders, engaged in any

Board Opinion No. 16, the interpretative releases issued pursuant thereto and
the pronouncements of the Securities and Exchange Commission ("SEC").

<PAGE>   24
OR THE OTHER DOCUMENTS TO BE EXECUTED IN CONNECTION HEREWITH, OR.

         (VIII)  ANY ACCRUED UNFUNDED RETIREMENT OR PENSION PLAN LIABILITIES.

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.

         11.4    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.

         11.5    LIMITATION ON INDEMNIFICATION.  Notwithstanding anything
contained herein to the contrary, any indemnification by the Company and
Shareholders in favor of PRG or PRG Sub shall not exceed in all cases the
Escrowed Shares, and any indemnification by PRG and PRG Sub in favor of the
Company and Shareholders shall not exceed in all cases the Escrowed Shares.
Furthermore, no claim for Damages shall be made by any party more than one (1)
year after the Closing Date.

         11.6    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
Corporation covering taxable periods ending on or before the Closing Date which
have not been filed on or before the Closing Date.  Shareholders 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 Corporation for all taxes (excluding, however, income taxes of the
Company and the tax liabilities, if any, disclosed on the Financial
Statements), 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"). Shareholders 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 Corporation for all Taxes for any Straddle





                                       23
<PAGE>   25
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, 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 August 31, 1996; or

         (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.


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):





                                       24
<PAGE>   26
                 (a)      except as set forth on Exhibit 13.1(a),  attached
hereto, 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 by PRG, PRG Sub, Surviving Corporation or any
practice managed by PRG or any subsidiary of PRG anywhere within, as of the
Closing Date, (i) 25 miles of any location of the Clinic, the practices set
forth on Exhibit 13.1(a), and any ophthalmology practice managed by PRG or any
subsidiary of PRG located outside of a Standard Statistical Metropolitan Area
having a population of greater than 1,000,000, or (ii) 10 miles of any location
of any ophthalmology practice managed by PRG or any subsidiary of PRG located
within a Standard Statistical Metropolitan Area having a population of greater
than 1,000,000; provided, however, that this provision shall not prohibit (a)
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) a Shareholder from performing surgery at any hospital or outpatient
surgical facility which provides services similar to those provided by the
Clinic, PRG or any of its Affiliates; 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 on Schedule 13.2.

         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 are not consummated for any
reason but otherwise shall not be affected by any breach of any other provision
hereof by any party hereto.  The covenants contained in this Section 13 shall
terminate in the event the Service Agreement is terminated pursuant to Section
3.11 or Section 9.3 thereto.

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    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.

on, and shall inure to the benefit of, the parties hereto, and their respective
successors and assigns, and no other person shall acquire or have any right

         16.11   NO RULE OF CONSTRUCTION.  The parties acknowledge that this
Agreement was initially prepared by PRG Sub, and that all parties have read and

Corporation or PRG, on the one hand, or the Company or the Shareholders, on the

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.

         16.13   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
signed by the parties hereto.  The waiver of any of the terms and conditions of
this Agreement shall not be construed as a waiver of any other terms and
conditions hereof.

         16.14   CHOICE OF FORUM.  Each of the parties hereto agree that should
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.

         16.15   SERVICE OF PROCESS.  Service of any and all process that may
be served on any party hereto in any suit, action or proceeding arising out of
this Agreement may be made in the manner and to the address set forth in
Section 16.1 and service thus made shall be taken and held to be valid personal
service upon such party by any party hereto on whose behalf such service is
made.

         16.16   SEVERABILITY.  If any provision of this Agreement shall be
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.

         16.17   ARBITRATION.  Except for matters for which an injunction,
restraining order, writ of mandamus, specific





                                       28

performance or other equitable relief may be sought by a party hereunder, any
disputes between the parties arising out of or otherwise relating to this
Agreement (whether based in contract, tort, or other legal theory), shall be
resolved by and through an arbitration proceeding to be conducted under the
auspices of the American Arbitration Association (or any like organization
successor thereto) in Dallas, Texas.  Such arbitration proceeding shall be
conducted in as expedited a manner as is then permitted by the commercial
arbitration rules (formal or informal) of the American Arbitration Association,
and the arbitrator or arbitrators in any such arbitration shall be persons who
are expert in the subject matter of the dispute.  Both the foregoing agreement
of the parties to arbitrate any and all such claims, and the results,
determination, finding, judgment and/or award rendered through such
Arbitration, shall be final and binding on the parties hereto and may be
specifically enforced by legal proceedings, and the parties agree that a
judgment of any court of competent jurisdiction may be rendered upon any
arbitration rendered pursuant to this Section.  Such arbitration may be
initiated by written notice from any party to the others which shall be a
compulsory and binding proceeding on each party.  The arbitration shall be
conducted before a panel of arbitrators selected in accordance with the rules
of the American Arbitration Association.  The costs of the arbitrators and the
arbitration, including the cost of their respective attorneys, witnesses and
experts in connection with such arbitration, incurred by the prevailing party
in the arbitration shall be paid by the other parties thereto.  Time is of the
essence of this arbitration procedure, and the arbitrators shall be instructed
and required to render their decision within ten (10) days following completion
of the arbitration.  Any and all legal proceedings to enforce this Agreement
(including any action to compel arbitration hereunder or to enforce any award
or judgment rendered thereby) shall be governed in accordance with this
Section.

         16.18   GOOD FAITH.  The parties agree to act in good faith and
reasonably with respect to the exercise of their respective rights, duties and
obligations .

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 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
pending or in process, or to the knowledge of the Company and Shareholders,
threatened.  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    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,





                                       8
<PAGE>   10
and whether due or to become due, other than those incurred in the ordinary
course of business.  The Company and the Shareholders do not know, or have
reasonable grounds to know, of any basis for the assertion against the Company
as of the Balance Sheet Date, of any claim or liability of any nature in any
amount not fully reflected or reserved against on the Balance Sheet, or of any
claim or liability of any nature arising since that date other than those
incurred in the ordinary course of business or contemplated by this Agreement.
All indebtedness of the Company (including without limitation, indebtedness for
borrowed money, guaranties and capital lease obligations) is described on
Exhibit 2.18 attached hereto.

         2.19    INSURANCE POLICIES.  The Company, each Shareholder and each
physician employee of the Company carries property, liability, malpractice,
workers' compensation and such other types of insurance as is customary in the
industry.  Valid 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 2.19 attached hereto and true and correct
copies have been delivered to PRG Sub.  Neither the Company nor any Shareholder
has received notice or other communication from the issuer of any such
insurance policy cancelling or amending such policy or threatening to do so.
Neither the Company, nor each Shareholder nor any physician employee of the
Company has any outstanding claims, settlements or premiums owed against any
insurance policy.

         2.20    EMPLOYEE BENEFIT PLANS.  Except as set forth on Exhibit 2.20
attached hereto, the Company has neither established, nor maintains, nor is
obligated to make contributions to or under or otherwise participate in, (a)
any bonus or other type of compensation or employment plan, program, agreement,
policy, commitment, contract or arrangement (whether or not set forth in a
written document); (b) any pension, profit-sharing, retirement or other plan,
program or arrangement; or (c) any other employee benefit plan, fund or
program, including, but not limited to, those described in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA").  All
such plans listed on Exhibit 2.20 (individually "Company Plan," and
collectively "Company Plans") have been operated and administered in all
material respects in accordance with all applicable laws, rules and
regulations, including without limitation, ERISA, the Internal Revenue Code of
1986, as amended, Title VII of the Civil Rights Act of 1964, as amended, the
Equal Pay Act of 1967, as amended, the Age Discrimination in Employment Act of
1967, as amended, and the related rules and regulations adopted by those
federal agencies responsible for the administration of such laws.  No act or
failure to act by the Company has resulted in a "prohibited transaction" (as
defined in ERISA) with respect to the Company Plans.  No "reportable event" (as
defined in ERISA) has occurred with respect to any of the Company Plans.  The
Company has not previously made, is not currently making, and is not obligated
in any way to make, any contributions to any multiemployer plan within the
meaning of the Multi-Employer Pension Plan Amendments Act of 1980.  With
respect to each Company Plan, either (i) the value of plan assets (including
commitments under insurance contracts) is at least equal to the value of plan
liabilities or (ii) the value of plan liabilities in excess of plan assets is
disclosed on the Balance Sheet, all as of the Closing Date.

         2.21    ADVERSE AGREEMENTS.  The Company is not, and will not be as of
the Closing Date, a party to any agreement or instrument or subject to any
charter or other corporate 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 Company.

         2.22    COMPLIANCE WITH LAWS IN GENERAL.  The Company, the

all applicable laws, rules, regulations and licensing requirements, including,
without limitation, the Federal Environmental Protection Act, the Occupational
Safety and Health Act, the Americans with Disabilities Act and any
environmental laws and medical waste laws, and there exist no violations by the
Company, any Shareholder or any physician or licensed employee of the Company
of any federal, state or local law or regulation.  Neither the Company nor any

business and assets of the Company and no notice of any pending inspection or
violation of any such law, regulation or ordinance has been received by the

adjustments, challenges, audit, litigation or notices of intent to open
Medicare or Medicaid claim determinations or other reports required to be filed

CONSULTANTS, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS AND AFFILIATES OF STATE OR
FEDERAL LAWS GOVERNING HEALTHCARE FRAUD AND ABUSE, WHETHER ON OR AFTER THE
CLOSING DATE,

         (V)      ANY OVERPAYMENT OR OBLIGATION ARISING OUT OF OR RESULTING

PRIOR TO THE CLOSING DATE,

         (VI)    TAXES OF THE COMPANY OR ANY OTHER PERSON (INCLUDING ANY
SHAREHOLDER) ARISING FROM OR AS A RESULT OF THE TRANSACTIONS CONTEMPLATED BY
THIS AGREEMENT (NOT INCLUDING INCOME TAXES OF THE COMPANY),

         (VII)   ANY LIABILITY OF THE COMPANY OR THE SHAREHOLDERS FOR COSTS AND

OR THE OTHER DOCUMENTS TO BE EXECUTED IN CONNECTION HEREWITH, OR.

         (VIII)  ANY ACCRUED UNFUNDED RETIREMENT OR PENSION PLAN LIABILITIES.

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.

         11.4    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.

         11.5    LIMITATION ON INDEMNIFICATION.  Notwithstanding anything
contained herein to the contrary, any indemnification by the Company and
Shareholders in favor of PRG or PRG Sub shall not exceed in all cases the
Escrowed Shares, and any indemnification by PRG and PRG Sub in favor of the
Company and Shareholders shall not exceed in all cases the Escrowed Shares.
Furthermore, no claim for Damages shall be made by any party more than one (1)
year after the Closing Date.

         11.6    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
Corporation covering taxable periods ending on or before the Closing Date which
have not been filed on or before the Closing Date.  Shareholders 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 Corporation for all taxes (excluding, however, income taxes of the
Company and the tax liabilities, if any, disclosed on the Financial
Statements), 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"). Shareholders 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 Corporation for all Taxes for any Straddle





                                       23
<PAGE>   25
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, 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 August 31, 1996; or

         (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.


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):





                                       24
<PAGE>   26
                 (a)      except as set forth on Exhibit 13.1(a),  attached
hereto, 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 by PRG, PRG Sub, Surviving Corporation or any
practice managed by PRG or any subsidiary of PRG anywhere within, as of the
Closing Date, (i) 25 miles of any location of the Clinic, the practices set
forth on Exhibit 13.1(a), and any ophthalmology practice managed by PRG or any
subsidiary of PRG located outside of a Standard Statistical Metropolitan Area
having a population of greater than 1,000,000, or (ii) 10 miles of any location
of any ophthalmology practice managed by PRG or any subsidiary of PRG located
within a Standard Statistical Metropolitan Area having a population of greater
than 1,000,000; provided, however, that this provision shall not prohibit (a)
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) a Shareholder from performing surgery at any hospital or outpatient
surgical facility which provides services similar to those provided by the
Clinic, PRG or any of its Affiliates; 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 on Schedule 13.2.

         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 are not consummated for any
reason but otherwise shall not be affected by any breach of any other provision
hereof by any party hereto.  The covenants contained in this Section 13 shall
terminate in the event the Service Agreement is terminated pursuant to Section
3.11 or Section 9.3 thereto.

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    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.

         16.9    COUNTERPARTS.  This Agreement may be executed in several
counterparts, each of which when so executed shall be deemed to be an original,
and such counterparts shall together constitute and be one and the same
instrument

         16.10   BINDING EFFECT/ASSIGNMENT.  This Agreement shall be binding
on, and shall inure to the benefit of, the parties hereto, and their respective
successors and assigns, and no other person shall acquire or have any right

lenders.

         16.11   NO RULE OF CONSTRUCTION.  The parties acknowledge that this

         16.12   COSTS OF ENFORCEMENT. In the event that PRG Sub, Surviving
Corporation or PRG, on the one hand, or the Company or the Shareholders, on the
other hand, file suit in any court against any other party to enforce the terms
of this Agreement against the other party or to obtain performance by it
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.

         16.13   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
signed by the parties hereto.  The waiver of any of the terms and conditions of
this Agreement shall not be construed as a waiver of any other terms and
conditions hereof.

         16.14   CHOICE OF FORUM.  Each of the parties hereto agree that should
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.

         16.15   SERVICE OF PROCESS.  Service of any and all process that may
be served on any party hereto in any suit, action or proceeding arising out of
this Agreement may be made in the manner and to the address set forth in
Section 16.1 and service thus made shall be taken and held to be valid personal
service upon such party by any party hereto on whose behalf such service is
made.

         16.16   SEVERABILITY.  If any provision of this Agreement shall be
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.

         16.17   ARBITRATION.  Except for matters for which an injunction,
restraining order, writ of mandamus, specific





                                       28
<PAGE>   30
performance or other equitable relief may be sought by a party hereunder, any
disputes between the parties arising out of or otherwise relating to this
Agreement (whether based in contract, tort, or other legal theory), shall be
resolved by and through an arbitration proceeding to be conducted under the
auspices of the American Arbitration Association (or any like organization
successor thereto) in Dallas, Texas.  Such arbitration proceeding shall be
conducted in as expedited a manner as is then permitted by the commercial
arbitration rules (formal or informal) of the American Arbitration Association,
and the arbitrator or arbitrators in any such arbitration shall be persons who
are expert in the subject matter of the dispute.  Both the foregoing agreement
of the parties to arbitrate any and all such claims, and the results,
determination, finding, judgment and/or award rendered through such
Arbitration, shall be final and binding on the parties hereto and may be
specifically enforced by legal proceedings, and the parties agree that a
judgment of any court of competent jurisdiction may be rendered upon any
arbitration rendered pursuant to this Section.  Such arbitration may be
initiated by written notice from any party to the others which shall be a
compulsory and binding proceeding on each party.  The arbitration shall be
conducted before a panel of arbitrators selected in accordance with the rules
of the American Arbitration Association.  The costs of the arbitrators and the
arbitration, including the cost of their respective attorneys, witnesses and
experts in connection with such arbitration, incurred by the prevailing party
in the arbitration shall be paid by the other parties thereto.  Time is of the
essence of this arbitration procedure, and the arbitrators shall be instructed
and required to render their decision within ten (10) days following completion
of the arbitration.  Any and all legal proceedings to enforce this Agreement
(including any action to compel arbitration hereunder or to enforce any award
or judgment rendered thereby) shall be governed in accordance with this
Section.

         16.18   GOOD FAITH.  The parties agree to act in good faith and
reasonably with respect to the exercise of their respective rights, duties and
obligations .

("PRG Sub"); PHYSICIANS RESOURCE GROUP, INC., a Delaware corporation ("PRG");

                                  WITNESSETH:

         WHEREAS, the Company operates an ophthalmology practice in Tampa, 
Florida;

         WHEREAS, Shareholders are the only shareholders of the Company;

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

         WHEREAS, the Boards of Directors of each of the Company, PRG and PRG

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)

financial accounting purposes 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:

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

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 Florida Business Corporation Law.

<PAGE>   3
         1.2     MERGER CERTIFICATES.  If all conditions to the Merger set

Effective on the Closing Date, the Certificate of Incorporation of PRG Sub
shall be the Articles of Incorporation of the Surviving Corporation and to the
extent the foregoing is not permitted by law, the Articles of Incorporation of
the Surviving Corporation shall be the Articles of Incorporation of the Company
and shall immediately be amended to contain the terms and provisions of the
Articles of Incorporation of PRG Sub.

         1.4     BYLAWS OF THE SURVIVING CORPORATION.  The Bylaws of PRG Sub on
the Closing Date shall be the Bylaws of the Surviving Corporation, until duly
amended in accordance with their terms.

         1.5     DIRECTORS OF THE SURVIVING CORPORATION.  The persons who are
directors of PRG Sub immediately prior to the Closing Date shall, from and

         1.7     CONVERSION OF COMPANY COMMON STOCK.  The manner of converting
shares of the Company 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 shares of Company common stock issued and
outstanding 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 fully registered shares of PRG common stock set forth on

Consideration").  As a result of the Merger and without any action on the part
of the holder thereof, all shares of the Company shall cease to be outstanding

a certificate representing any such shares of Company common stock shall
thereafter cease to have any rights with respect to such shares of Company
common stock, except the right to receive, without interest, the Merger
Consideration.

                 (b)      Each share of Company common stock held in the
Company's treasury, if any, on the Closing Date, by virtue of the Merger, shall
cease to be outstanding and shall be cancelled and retired without payment of
any consideration therefor and shall cease to exist.

                 (c)      On the Closing Date, each share of PRG Sub common
stock issued and outstanding as of the Closing Date shall be surrendered in
exchange for a share of validly issued, fully paid and nonassessable share of
common stock of Surviving Corporation.

         1.8     EXCHANGE OF CERTIFICATES REPRESENTING SHARES OF COMPANY COMMON
STOCK.

                 (a)      At or after the Closing Date, (i) the Shareholders,
as the holders of all outstanding certificates representing shares of Company
common stock, shall, upon surrender of such certificates, be entitled to
receive the Merger Consideration and (ii) until the certificates representing
Company common stock have been surrendered by Shareholders and replaced by
certificates representing PRG common stock, the certificates for Company common
stock shall, for all purposes, be deemed to evidence ownership of PRG common
stock.

with all necessary transfer tax and other revenue stamps, acquired at the
Shareholders' expense, affixed and cancelled.  The Shareholders agree to cure
any deficiencies with respect to the endorsement of the certificates or other
documents of conveyance with respect to such Company common stock or with
respect to the stock powers accompanying any Company Common Stock.  Upon such
delivery, the Shareholder shall be entitled to receive in exchange therefor a
certificate representing that number of shares of PRG common stock Shareholder
is entitled to receive pursuant to Section 1.7.

Sub, PRG and Jackson &Walker, L.L.P. , 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 Sub may be entitled to indemnification
pursuant to Article XI in accordance with the terms of the Escrow Agreement.

         1.10    SUBSEQUENT ACTIONS. If, at any time after the Closing Date,
the Surviving Corporation 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
Corporation its right, title or interest in, to or under any of the rights,

SECTION 2.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY AND THE
SHAREHOLDERS.

         The Company and the Shareholders, jointly (with respect to
representations and warranties by such Shareholder or the Company) and
severally (with respect to representations and warranties by such Shareholder),
hereby represent and warrant to PRG Sub and PRG as follows:

         2.1     CORPORATE EXISTENCE; GOOD STANDING.  The Company is a
professional association duly organized, validly existing and in good standing
under the laws of the State of Florida.  The Company has all necessary
corporate powers to own all of its assets and to carry on its business as such
business is now being conducted.  The Company does not own stock in or control,
directly or indirectly, any other corporation, association or business
organization, nor is the Company a party to any joint venture or partnership.
The shareholders are the sole shareholders of the Company and own all
outstanding shares of capital stock free of all security interests, claims,
encumbrances and liens in the amounts set forth on Exhibit 2.1.  The
Shareholders have owned the equity interests set forth on Exhibit 2.1 since
January 1, 1994 in the amounts set forth on such Exhibit.  Each share of
Company common stock has been legally and validly issued and fully paid and
nonassessable.  No shares of capital stock of the Company are owned by the
Company in treasury. The Company has not acquired any treasury shares since
January 1, 1994.  There are no outstanding (a) bonds, debentures, notes or
other obligations the holders of which have the right to vote with the
stockholders of the Company on any matter, (b) securities of the Company
convertible into equity interests in the Company, or (c) commitments,





                                       3
<PAGE>   5
options, rights or warrants to issue any such equity interests in the Company,
to issue securities of the Company convertible into such equity interests, or
to redeem any securities of the Company. No shares of capital stock of the
Company have been issued or disposed of in violation of the preemptive rights,
rights of first refusal or similar rights of any of the Company's stockholders.
The Company is not required to qualify to do business as a foreign corporation
in any other state or jurisdiction by reason of its business, properties or
activities in or relating to such other state or jurisdiction.  The Company
does not have any assets, employees or offices in any state other than Florida.

         The Company has not been a division or subsidiary of PRG or any of its
subsidiaries since January 1, 1994.  The Company and each Shareholder do not
own any stock of PRG.

         2.2     POWER AND AUTHORITY FOR TRANSACTIONS.  The Company has the
corporate power to execute, deliver and perform this Agreement and all
agreements and other documents executed and delivered by it pursuant to this
Agreement or to be executed and delivered on the Closing Date, and has taken
all action required by law, its Articles of Incorporation, its Bylaws or
otherwise, to authorize the execution, delivery and performance of this
Agreement and such related documents.  Each Shareholder has the legal capacity
to enter into and perform this Agreement and the other agreements to be
executed and delivered in connection herewith.  The Company has obtained the
approval of its stockholders necessary to the consummation of the transactions
contemplated herein.  This Agreement and all agreements and documents executed
and delivered in connection herewith have been, or will be as of the Closing
Date, duly executed and delivered by the Company and the Shareholders, as
appropriate, and constitute or will constitute the legal, valid and binding
obligations of the Company and the Shareholders, enforceable against the
Company and the Shareholders in accordance with their respective terms, except
as may be limited by applicable bankruptcy, insolvency or similar laws
affecting creditors' rights generally or the availability of equitable
remedies.  The execution and delivery of this Agreement, and the agreements
executed and delivered pursuant to this Agreement or to be executed and
delivered on the Closing Date, do not, and, subject to the receipt of consents
described on Exhibit 2.5, the consummation of the actions contemplated hereby
will not, violate any provision of the Articles of Incorporation or Bylaws of
the Company or any provisions of, or result in the acceleration of, any
obligation under any mortgage, lien, lease, agreement, rent, instrument, order,
arbitration award, judgment or decree to which the Company or any Shareholder
is a party or by which the Company or any Shareholder is bound, or violate any
material restrictions of any kind to which the Company is subject, or result in
any lien or encumbrance on any of the Company's assets.

         2.3     PERMITS, LICENSES AND GOVERNMENTAL AUTHORIZATIONS.  All
building or other permits, certificates of occupancy, concessions, grants,
franchises, licenses, certificates of need and other governmental
authorizations and approvals required to be maintained by the Company, the
Shareholders and each physician or licensed employee of the Company have been
duly obtained and are in full force and effect and are described on Exhibit
2.3.  There are no proceedings pending or, to the knowledge of the Company and
the Shareholders, threatened, which may result in the revocation, cancellation
or suspension, or any adverse modification, of any thereof.

         2.4     CORPORATE RECORDS.  True and correct copies of the Articles of
Incorporation, Bylaws and minutes of the Company and all amendments thereto of
the Company have been delivered to PRG Sub.  The minute books of the Company

without meetings of the Board of Directors and stockholders of the Company
since its formation.

         2.5     CONSENTS.  Except as set forth on Exhibit 2.5, no consent,
authorization, permit, license or filing with any governmental authority, any
lender, lessor, any manufacturer or supplier or any other person or entity is
required to authorize, or is required in connection with, the execution,
delivery and performance of this Agreement and the agreements and documents
contemplated hereby on the part of the Company or the Shareholders.

         2.6     THE COMPANY'S FINANCIAL INFORMATION.  The Company has
heretofore furnished PRG Sub with financial information about the Company,
which information is set forth in the financial statements on Exhibit 2.6

to be reported in accordance with GAAP, as of their respective dates, and

leases pursuant to which the Company leases, as lessor or lessee, real or
personal property used in operating the business of the Company or otherwise.
All such leases listed on Exhibit 2.7 are valid and enforceable in accordance
with their respective terms, and there is not under any such lease any existing
material default by the Company, as lessor or lessee, or any condition or event
of which the Company or any Shareholder has knowledge which with notice or
lapse of time, or both, would constitute a material default, in respect of
which the Company has not taken adequate steps to cure such default or to
prevent a default from occurring.

         2.8     CONDITION OF ASSETS.  All of the plants, structures and
equipment used by the Company in its business are in good condition and repair
subject to normal wear and tear and conform with all applicable ordinances,

operations of the Company infringe upon or conflict with the asserted rights of
others to any patents, patent rights, manufacturing processes, trade names,
trademarks, service marks, inventions, licenses, specialized treatment
protocols, copyrights, formulas, know-how and trade secrets.  The Company has
the sole and exclusive right to use all such proprietary rights without

         2.13    LEGAL PROCEEDINGS.  Neither the Company nor any Shareholder

Company, any Shareholder, the outstanding shares of the Company's stock, any of
the assets of the Company, the operations, business or prospects of the Company
or the transactions contemplated by this Agreement, and, to the knowledge of
the Company and the Shareholders, no basis for any such action exists, nor is

Company nor the Shareholders have received notice of the intention of any party

of the Company or to the assets of the Company.

         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 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
pending or in process, or to the knowledge of the Company and Shareholders,
threatened.  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    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,





                                       8
<PAGE>   10
and whether due or to become due, other than those incurred in the ordinary
course of business.  The Company and the Shareholders do not know, or have
reasonable grounds to know, of any basis for the assertion against the Company
as of the Balance Sheet Date, of any claim or liability of any nature in any
amount not fully reflected or reserved against on the Balance Sheet, or of any
claim or liability of any nature arising since that date other than those
incurred in the ordinary course of business or contemplated by this Agreement.
All indebtedness of the Company (including without limitation, indebtedness for
borrowed money, guaranties and capital lease obligations) is described on
Exhibit 2.18 attached hereto.

         2.19    INSURANCE POLICIES.  The Company, each Shareholder and each
physician employee of the Company carries property, liability, malpractice,
workers' compensation and such other types of insurance as is customary in the
industry.  Valid 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 2.19 attached hereto and true and correct
copies have been delivered to PRG Sub.  Neither the Company nor any Shareholder
has received notice or other communication from the issuer of any such
insurance policy cancelling or amending such policy or threatening to do so.
Neither the Company, nor each Shareholder nor any physician employee of the
Company has any outstanding claims, settlements or premiums owed against any
insurance policy.

         2.20    EMPLOYEE BENEFIT PLANS.  Except as set forth on Exhibit 2.20
attached hereto, the Company has neither established, nor maintains, nor is
obligated to make contributions to or under or otherwise participate in, (a)
any bonus or other type of compensation or employment plan, program, agreement,
policy, commitment, contract or arrangement (whether or not set forth in a
written document); (b) any pension, profit-sharing, retirement or other plan,
program or arrangement; or (c) any other employee benefit plan, fund or
program, including, but not limited to, those described in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA").  All
such plans listed on Exhibit 2.20 (individually "Company Plan," and
collectively "Company Plans") have been operated and administered in all
material respects in accordance with all applicable laws, rules and
regulations, including without limitation, ERISA, the Internal Revenue Code of
1986, as amended, Title VII of the Civil Rights Act of 1964, as amended, the
Equal Pay Act of 1967, as amended, the Age Discrimination in Employment Act of
1967, as amended, and the related rules and regulations adopted by those
federal agencies responsible for the administration of such laws.  No act or
failure to act by the Company has resulted in a "prohibited transaction" (as
defined in ERISA) with respect to the Company Plans.  No "reportable event" (as
defined in ERISA) has occurred with respect to any of the Company Plans.  The
Company has not previously made, is not currently making, and is not obligated
in any way to make, any contributions to any multiemployer plan within the
meaning of the Multi-Employer Pension Plan Amendments Act of 1980.  With
respect to each Company Plan, either (i) the value of plan assets (including
commitments under insurance contracts) is at least equal to the value of plan
liabilities or (ii) the value of plan liabilities in excess of plan assets is
disclosed on the Balance Sheet, all as of the Closing Date.

         2.21    ADVERSE AGREEMENTS.  The Company is not, and will not be as of
the Closing Date, a party to any agreement or instrument or subject to any
charter or other corporate 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 Company.

         2.22    COMPLIANCE WITH LAWS IN GENERAL.  The Company, the
Shareholders and Company's physician and licensed employees 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 Americans with Disabilities Act and any
environmental laws and medical waste laws, and there exist no violations by the
Company, any Shareholder or any physician or licensed employee of the Company
of any federal, state or local law or regulation.  Neither the Company nor any
Shareholder has received any notice of a violation of any federal, state and
local laws, regulations and ordinances relating to the operations of the
business and assets of the Company and no notice of any pending inspection or
violation of any such law, regulation or ordinance has been received by the
Company or any Shareholder.

         2.23    MEDICARE AND MEDICAID PROGRAMS.  The Company, each Shareholder
and each physician and

which are in full force and effect with no defaults having occurred thereunder.
The Company, each Shareholder and each physician and licensed employee of the
Company has timely filed all claims or other reports required to be filed with
respect to the purchase of services by third-party payors, and all such claims
or reports are complete and accurate, and has no liability to any payor with
respect thereto.  There are no pending appeals, overpayment determinations,
adjustments, challenges, audit, litigation or notices of intent to open
Medicare or Medicaid claim determinations or other reports required to be filed
by the Company, each Shareholder and each licensed employee of the Company.
Neither the Company, nor any Shareholder, nor any physician or licensed
employee of the Company has been convicted of, or pled guilty or nolo
contendere to, patient abuse or negligence, or any other Medicare or Medicaid
program related offense and none has committed any offense which may serve as
the basis for suspension or exclusion from the Medicare and Medicaid programs.

         2.24    FRAUD AND ABUSE.  The Company, the Shareholders and all
persons and entities providing professional services for the Company's business
have not, to the knowledge of the Company and the Shareholders, engaged in any

Board Opinion No. 16, the interpretative releases issued pursuant thereto and
the pronouncements of the Securities and Exchange Commission ("SEC").

<PAGE>   24
OR THE OTHER DOCUMENTS TO BE EXECUTED IN CONNECTION HEREWITH, OR.

         (VIII)  ANY ACCRUED UNFUNDED RETIREMENT OR PENSION PLAN LIABILITIES.

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.

         11.4    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.

         11.5    LIMITATION ON INDEMNIFICATION.  Notwithstanding anything
contained herein to the contrary, any indemnification by the Company and
Shareholders in favor of PRG or PRG Sub shall not exceed in all cases the
Escrowed Shares, and any indemnification by PRG and PRG Sub in favor of the
Company and Shareholders shall not exceed in all cases the Escrowed Shares.
Furthermore, no claim for Damages shall be made by any party more than one (1)
year after the Closing Date.

         11.6    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
Corporation covering taxable periods ending on or before the Closing Date which
have not been filed on or before the Closing Date.  Shareholders 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 Corporation for all taxes (excluding, however, income taxes of the
Company and the tax liabilities, if any, disclosed on the Financial
Statements), 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"). Shareholders 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 Corporation for all Taxes for any Straddle





                                       23
<PAGE>   25
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, 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 August 31, 1996; or

         (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.


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):





                                       24
<PAGE>   26
                 (a)      except as set forth on Exhibit 13.1(a),  attached
hereto, 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 by PRG, PRG Sub, Surviving Corporation or any
practice managed by PRG or any subsidiary of PRG anywhere within, as of the
Closing Date, (i) 25 miles of any location of the Clinic, the practices set
forth on Exhibit 13.1(a), and any ophthalmology practice managed by PRG or any
subsidiary of PRG located outside of a Standard Statistical Metropolitan Area
having a population of greater than 1,000,000, or (ii) 10 miles of any location
of any ophthalmology practice managed by PRG or any subsidiary of PRG located
within a Standard Statistical Metropolitan Area having a population of greater
than 1,000,000; provided, however, that this provision shall not prohibit (a)
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) a Shareholder from performing surgery at any hospital or outpatient
surgical facility which provides services similar to those provided by the
Clinic, PRG or any of its Affiliates; 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 on Schedule 13.2.

         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 are not consummated for any
reason but otherwise shall not be affected by any breach of any other provision
hereof by any party hereto.  The covenants contained in this Section 13 shall
terminate in the event the Service Agreement is terminated pursuant to Section
3.11 or Section 9.3 thereto.

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    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.

or supplemented only by an instrument in writing executed by all the parties

to institute proceedings only in a state or federal court in Dallas County,
Texas.

service upon such party by any party hereto on whose behalf such service is
made.

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.

restraining order, writ of mandamus, specific

Agreement (whether based in contract, tort, or other legal theory), shall be
resolved by and through an arbitration proceeding to be conducted under the
auspices of the American Arbitration Association (or any like organization
successor thereto) in Dallas, Texas.  Such arbitration proceeding shall be
conducted in as expedited a manner as is then permitted by the commercial
arbitration rules (formal or informal) of the American Arbitration Association,
and the arbitrator or arbitrators in any such arbitration shall be persons who
are expert in the subject matter of the dispute.  Both the foregoing agreement
of the parties to arbitrate any and all such claims, and the results,
determination, finding, judgment and/or award rendered through such
Arbitration, shall be final and binding on the parties hereto and may be
specifically enforced by legal proceedings, and the parties agree that a
judgment of any court of competent jurisdiction may be rendered upon any
arbitration rendered pursuant to this Section.  Such arbitration may be

arbitration, including the cost of their respective attorneys, witnesses and
experts in connection with such arbitration, incurred by the prevailing party

and required to render their decision within ten (10) days following completion
of the arbitration.  Any and all legal proceedings to enforce this Agreement
(including any action to compel arbitration hereunder or to enforce any award
or judgment rendered thereby) shall be governed in accordance with this
Section.

         16.18   GOOD FAITH.  The parties agree to act in good faith and
reasonably with respect to the exercise of their respective rights, duties and
obligations .

                          AGREEMENT AND PLAN OF MERGER


         This AGREEMENT AND PLAN OF MERGER, made and executed as of the 13th day
of August, 1996, is by and among PRG VI ACQ. CORP., a Delaware corporation ("PRG
Sub"); PHYSICIANS RESOURCE GROUP, INC., a Delaware corporation ("PRG"); J.
BURNS CREIGHTON, M.D., P.A., a Florida professional corporation (the Company"),
and J. BURNS CREIGHTON, M.D., an individual resident of the State of 
Florida (the "Shareholder").





                                  WITNESSETH:

         WHEREAS, the Company operates an ophthalmology practice in Tampa, 
Florida;

         WHEREAS, Shareholders are the only shareholders of the Company;

         WHEREAS, PRG Sub is engaged in the business of acquiring the assets of
and operating 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"), and for
financial accounting purposes 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 Sub with and into the Company shall occur on the
31st day of August, 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 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 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 Florida 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 Florida Business Corporation Law.

         1.2     MERGER CERTIFICATES.  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 shall cause to be properly executed and filed on the Closing
Date Articles of Merger meeting the requirements of the Florida Business
Corporation Law.  The Merger shall become effective on the Closing Date.

         1.3     CERTIFICATE OF INCORPORATION OF SURVIVING CORPORATION.
Effective on the Closing Date, the Certificate of Incorporation of PRG Sub
shall be the Articles of Incorporation of the Surviving Corporation and to the
extent the foregoing is not permitted by law, the Articles of Incorporation of
the Surviving Corporation shall be the Articles of Incorporation of the Company
and shall immediately be amended to contain the terms and provisions of the
Articles of Incorporation of PRG Sub.

         1.4     BYLAWS OF THE SURVIVING CORPORATION.  The Bylaws of PRG Sub on
the Closing Date shall be the Bylaws of the Surviving Corporation, until duly
amended in accordance with their terms.

         1.5     DIRECTORS OF THE SURVIVING CORPORATION.  The persons who are
directors of PRG Sub immediately prior to the Closing Date shall, from and

their successors have been duly elected or appointed and qualified or until
their earlier death, resignation or removal in accordance with the Surviving
Corporation's Articles or Certificate of Incorporation and Bylaws.

         1.6     OFFICERS OF THE SURVIVING CORPORATION.  The persons who are
officers of PRG Sub immediately prior to the Closing Date shall, from and after
the Closing Date, be the officers of the Surviving Corporation and shall hold
their same respective office(s) until their earlier death, resignation or
removal.

         1.7     CONVERSION OF COMPANY COMMON STOCK.  The manner of converting
shares of the Company 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 shares of Company common stock issued and
outstanding 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 fully registered 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 shares of the Company shall cease to be outstanding
and shall be cancelled and retired and shall cease to exist, and each holder of
a certificate representing any such shares of Company common stock shall
thereafter cease to have any rights with respect to such shares of Company
common stock, except the right to receive, without interest, the Merger

leases pursuant to which the Company leases, as lessor or lessee, real or
personal property used in operating the business of the Company or otherwise.
All such leases listed on Exhibit 2.7 are valid and enforceable in accordance
with their respective terms, and there is not under any such lease any existing
material default by the Company, as lessor or lessee, or any condition or event
of which the Company or any Shareholder has knowledge which with notice or
lapse of time, or both, would constitute a material default, in respect of
which the Company has not taken adequate steps to cure such default or to
prevent a default from occurring.

         2.8     CONDITION OF ASSETS.  All of the plants, structures and
equipment used by the Company in its business are in good condition and repair

no spinoffs of assets have occurred since January 1, 1994.

         2.10    INVENTORIES.  All inventories of the Company used in the

generally accepted accounting principles consistently applied.  The items of
the Company's inventory have been acquired in the ordinary course of its
business, are adequate for the reasonable requirements of its business, and, to
the best knowledge of the Company and the Shareholders, may be used for their
intended purposes.  All of the inventory owned or used by the Company is in
good, current, standard and merchantable condition and is not obsolete or
defective.

         2.11    INTELLECTUAL PROPERTY RIGHTS; NAMES.  Except as set forth on
Exhibit 2.11, the Company has no right, title or interest in or to patents,

patents, trademarks, service marks, trade names, copyrights or applications
therefor, or manufacturing processes, formulas or trade secrets or similar

claim is pending or has been made to the effect that the present or past
operations of the Company infringe upon or conflict with the asserted rights of
others to any patents, patent rights, manufacturing processes, trade names,
trademarks, service marks, inventions, licenses, specialized treatment
protocols, copyrights, formulas, know-how and trade secrets.  The Company has
the sole and exclusive right to use all such proprietary rights without

         2.12    DIRECTORS AND OFFICERS; PAYROLL INFORMATION; EMPLOYEES.  Set

not engaged in any unfair labor practice.  There are no unfair labor practices
charges or complaints pending or threatened against the Company, and the
Company has never been a party to any agreement with any union, labor

         2.13    LEGAL PROCEEDINGS.  Neither the Company nor any Shareholder
nor outstanding shares of the Company's stock nor any of the Company's assets
is subject to any pending, nor does the Company or any Shareholder have

of the Company or to the assets of the Company.

         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 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
pending or in process, or to the knowledge of the Company and Shareholders,
threatened.  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    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,





                                       8
<PAGE>   10
and whether due or to become due, other than those incurred in the ordinary
course of business.  The Company and the Shareholders do not know, or have
reasonable grounds to know, of any basis for the assertion against the Company
as of the Balance Sheet Date, of any claim or liability of any nature in any
amount not fully reflected or reserved against on the Balance Sheet, or of any
claim or liability of any nature arising since that date other than those
incurred in the ordinary course of business or contemplated by this Agreement.
All indebtedness of the Company (including without limitation, indebtedness for
borrowed money, guaranties and capital lease obligations) is described on
Exhibit 2.18 attached hereto.

         2.19    INSURANCE POLICIES.  The Company, each Shareholder and each
physician employee of the Company carries property, liability, malpractice,
workers' compensation and such other types of insurance as is customary in the
industry.  Valid 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 2.19 attached hereto and true and correct
copies have been delivered to PRG Sub.  Neither the Company nor any Shareholder
has received notice or other communication from the issuer of any such
insurance policy cancelling or amending such policy or threatening to do so.
Neither the Company, nor each Shareholder nor any physician employee of the
Company has any outstanding claims, settlements or premiums owed against any
insurance policy.

         2.20    EMPLOYEE BENEFIT PLANS.  Except as set forth on Exhibit 2.20
attached hereto, the Company has neither established, nor maintains, nor is
obligated to make contributions to or under or otherwise participate in, (a)
any bonus or other type of compensation or employment plan, program, agreement,
policy, commitment, contract or arrangement (whether or not set forth in a

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.

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.

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, 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 August 31, 1996; or

         (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.


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):





                                       24
<PAGE>   26
                 (a)      except as set forth on Exhibit 13.1(a),  attached
hereto, 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 by PRG, PRG Sub, Surviving Corporation or any
practice managed by PRG or any subsidiary of PRG anywhere within, as of the
Closing Date, (i) 25 miles of any location of the Clinic, the practices set
forth on Exhibit 13.1(a), and any ophthalmology practice managed by PRG or any
subsidiary of PRG located outside of a Standard Statistical Metropolitan Area
having a population of greater than 1,000,000, or (ii) 10 miles of any location
of any ophthalmology practice managed by PRG or any subsidiary of PRG located
within a Standard Statistical Metropolitan Area having a population of greater
than 1,000,000; provided, however, that this provision shall not prohibit (a)
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) a Shareholder from performing surgery at any hospital or outpatient
surgical facility which provides services similar to those provided by the
Clinic, PRG or any of its Affiliates; 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 on Schedule 13.2.

         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 are not consummated for any
reason but otherwise shall not be affected by any breach of any other provision
hereof by any party hereto.  The covenants contained in this Section 13 shall
terminate in the event the Service Agreement is terminated pursuant to Section
3.11 or Section 9.3 thereto.

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    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.

         16.9    COUNTERPARTS.  This Agreement may be executed in several
counterparts, each of which when so executed shall be deemed to be an original,

lenders.

         16.11   NO RULE OF CONSTRUCTION.  The parties acknowledge that this
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,

         16.12   COSTS OF ENFORCEMENT. In the event that PRG Sub, Surviving
Corporation or PRG, on the one hand, or the Company or the Shareholders, on the
other hand, file suit in any court against any other party to enforce the terms
of this Agreement against the other party or to obtain performance by it
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.

         16.13   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
signed by the parties hereto.  The waiver of any of the terms and conditions of
this Agreement shall not be construed as a waiver of any other terms and
conditions hereof.

         16.14   CHOICE OF FORUM.  Each of the parties hereto agree that should
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.

         16.15   SERVICE OF PROCESS.  Service of any and all process that may
be served on any party hereto in any suit, action or proceeding arising out of
this Agreement may be made in the manner and to the address set forth in
Section 16.1 and service thus made shall be taken and held to be valid personal
service upon such party by any party hereto on whose behalf such service is
made.

         16.16   SEVERABILITY.  If any provision of this Agreement shall be
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.

         16.17   ARBITRATION.  Except for matters for which an injunction,
restraining order, writ of mandamus, specific





                                       28
<PAGE>   30
performance or other equitable relief may be sought by a party hereunder, any
disputes between the parties arising out of or otherwise relating to this
Agreement (whether based in contract, tort, or other legal theory), shall be
resolved by and through an arbitration proceeding to be conducted under the
auspices of the American Arbitration Association (or any like organization
successor thereto) in Dallas, Texas.  Such arbitration proceeding shall be
conducted in as expedited a manner as is then permitted by the commercial
arbitration rules (formal or informal) of the American Arbitration Association,
and the arbitrator or arbitrators in any such arbitration shall be persons who
are expert in the subject matter of the dispute.  Both the foregoing agreement
of the parties to arbitrate any and all such claims, and the results,
determination, finding, judgment and/or award rendered through such
Arbitration, shall be final and binding on the parties hereto and may be
specifically enforced by legal proceedings, and the parties agree that a
judgment of any court of competent jurisdiction may be rendered upon any
arbitration rendered pursuant to this Section.  Such arbitration may be
initiated by written notice from any party to the others which shall be a
compulsory and binding proceeding on each party.  The arbitration shall be
conducted before a panel of arbitrators selected in accordance with the rules
of the American Arbitration Association.  The costs of the arbitrators and the
arbitration, including the cost of their respective attorneys, witnesses and
experts in connection with such arbitration, incurred by the prevailing party
in the arbitration shall be paid by the other parties thereto.  Time is of the
essence of this arbitration procedure, and the arbitrators shall be instructed
and required to render their decision within ten (10) days following completion
of the arbitration.  Any and all legal proceedings to enforce this Agreement
(including any action to compel arbitration hereunder or to enforce any award
or judgment rendered thereby) shall be governed in accordance with this
Section.

         16.18   GOOD FAITH.  The parties agree to act in good faith and
reasonably with respect to the exercise of their respective rights, duties and
obligations .

receive the Merger Consideration and (ii) until the certificates representing

stock shall, for all purposes, be deemed to evidence ownership of PRG common
stock.

         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 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
pending or in process, or to the knowledge of the Company and Shareholders,
threatened.  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    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,





                                       8
<PAGE>   10
and whether due or to become due, other than those incurred in the ordinary
course of business.  The Company and the Shareholders do not know, or have
reasonable grounds to know, of any basis for the assertion against the Company
as of the Balance Sheet Date, of any claim or liability of any nature in any
amount not fully reflected or reserved against on the Balance Sheet, or of any
claim or liability of any nature arising since that date other than those
incurred in the ordinary course of business or contemplated by this Agreement.
All indebtedness of the Company (including without limitation, indebtedness for
borrowed money, guaranties and capital lease obligations) is described on
Exhibit 2.18 attached hereto.

         2.19    INSURANCE POLICIES.  The Company, each Shareholder and each
physician employee of the Company carries property, liability, malpractice,
workers' compensation and such other types of insurance as is customary in the
industry.  Valid 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 2.19 attached hereto and true and correct
copies have been delivered to PRG Sub.  Neither the Company nor any Shareholder
has received notice or other communication from the issuer of any such
insurance policy cancelling or amending such policy or threatening to do so.
Neither the Company, nor each Shareholder nor any physician employee of the
Company has any outstanding claims, settlements or premiums owed against any
insurance policy.

         2.20    EMPLOYEE BENEFIT PLANS.  Except as set forth on Exhibit 2.20
attached hereto, the Company has neither established, nor maintains, nor is
obligated to make contributions to or under or otherwise participate in, (a)
any bonus or other type of compensation or employment plan, program, agreement,
policy, commitment, contract or arrangement (whether or not set forth in a
written document); (b) any pension, profit-sharing, retirement or other plan,
program or arrangement; or (c) any other employee benefit plan, fund or
program, including, but not limited to, those described in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA").  All
such plans listed on Exhibit 2.20 (individually "Company Plan," and
collectively "Company Plans") have been operated and administered in all
material respects in accordance with all applicable laws, rules and
regulations, including without limitation, ERISA, the Internal Revenue Code of
1986, as amended, Title VII of the Civil Rights Act of 1964, as amended, the
Equal Pay Act of 1967, as amended, the Age Discrimination in Employment Act of
1967, as amended, and the related rules and regulations adopted by those
federal agencies responsible for the administration of such laws.  No act or
failure to act by the Company has resulted in a "prohibited transaction" (as
defined in ERISA) with respect to the Company Plans.  No "reportable event" (as
defined in ERISA) has occurred with respect to any of the Company Plans.  The
Company has not previously made, is not currently making, and is not obligated
in any way to make, any contributions to any multiemployer plan within the
meaning of the Multi-Employer Pension Plan Amendments Act of 1980.  With
respect to each Company Plan, either (i) the value of plan assets (including
commitments under insurance contracts) is at least equal to the value of plan
liabilities or (ii) the value of plan liabilities in excess of plan assets is
disclosed on the Balance Sheet, all as of the Closing Date.

         2.21    ADVERSE AGREEMENTS.  The Company is not, and will not be as of
the Closing Date, a party to any agreement or instrument or subject to any
charter or other corporate 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 Company.

         2.22    COMPLIANCE WITH LAWS IN GENERAL.  The Company, the
Shareholders and Company's physician and licensed employees 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 Americans with Disabilities Act and any
environmental laws and medical waste laws, and there exist no violations by the
Company, any Shareholder or any physician or licensed employee of the Company
of any federal, state or local law or regulation.  Neither the Company nor any
Shareholder has received any notice of a violation of any federal, state and
local laws, regulations and ordinances relating to the operations of the
business and assets of the Company and no notice of any pending inspection or
violation of any such law, regulation or ordinance has been received by the
Company or any Shareholder.

         2.23    MEDICARE AND MEDICAID PROGRAMS.  The Company, each Shareholder

which are in full force and effect with no defaults having occurred thereunder.
The Company, each Shareholder and each physician and licensed employee of the
Company has timely filed all claims or other reports required to be filed with
respect to the purchase of services by third-party payors, and all such claims
or reports are complete and accurate, and has no liability to any payor with
respect thereto.  There are no pending appeals, overpayment determinations,
adjustments, challenges, audit, litigation or notices of intent to open
Medicare or Medicaid claim determinations or other reports required to be filed
by the Company, each Shareholder and each licensed employee of the Company.
Neither the Company, nor any Shareholder, nor any physician or licensed
employee of the Company has been convicted of, or pled guilty or nolo
contendere to, patient abuse or negligence, or any other Medicare or Medicaid
program related offense and none has committed any offense which may serve as

persons and entities providing professional services for the Company's business

SECTION 4.       CLOSING DATE REPRESENTATIONS AND WARRANTIES OF THE
SHAREHOLDERS.

         The Shareholders, jointly and severally, represent and warrant that
the following will be true and correct as of the Closing Date as if made on
such date:

         4.1     CORPORATE EXISTENCE AND GOOD STANDING OF THE CLINIC.   On or
prior to the Closing Date, the Shareholders shall form a Florida professional
service corporation (the "Clinic") which shall be duly organized, validly
existing and in good standing under the laws of the State of Florida. The
Clinic has all necessary corporate power to own all of its assets and to carry
on its business as such business is now being conducted.  The Shareholders are
the sole shareholders of the Clinic and own such interests free of all security
interests, claims, encumbrances and liens in the amounts set forth on Exhibit
4.1.  Each interest of the Clinic has been legally and validly issued and fully
paid and nonassessable.  There are no outstanding (a) bonds, debentures, notes
or other obligations the holders of which have the right to vote with the
shareholders of the Clinic on any matter, (b) securities of the Clinic
convertible into equity interests in the Clinic, or (c) commitments, options,
rights or warrants to issue any such equity interests in the Clinic, to issue
securities of the Clinic convertible into such equity interests, or to redeem
any securities of the Clinic.  No interests of the Clinic have been issued or
disposed of in violation of the preemptive rights, rights of first refusal or
similar rights of any of the Clinic's shareholders.  The Clinic is not required
to qualify to do business as a foreign entity in any other state or
jurisdiction by reason of its business, properties or activities in or relating
to such other state or jurisdiction.  The Clinic does not have any assets,
employees or offices in any state other than Florida.

         4.2     CORPORATE RECORDS.  True and correct copies of the Articles of
Incorporation, Bylaws and minutes of the Clinic and all amendments thereto of
the Clinic have been delivered to PRG and are in form and substance
satisfactory to PRG and PRG Sub.  The minute books of the Clinic contain all
accurate minutes of the meetings of and consents to actions taken without
meetings of the shareholders of the Clinic since its formation.  The books of
account of the Clinic have been kept accurately in the ordinary course of
business and the revenues, expenses, assets and liabilities of the Clinic have
been properly recorded in such books.

         4.3     POWER AND AUTHORITY FOR TRANSACTIONS.  The Clinic has the
corporate power to execute, deliver and perform its obligations under all
agreements and other documents to be executed and delivered by it pursuant to
this Agreement, including without limitation, the Service Agreement and each
Physician Employment Agreement or to be executed and delivered on the Closing
Date, and has taken all action required by law, its Articles of Incorporation,
its Bylaws or otherwise, to authorize the execution, delivery and performance
of such documents.  The Service Agreement, the Physician Employment Agreement
and the other agreements contemplated hereby have been duly executed and
delivered by the Clinic and constitute or will constitute the legal, valid and
binding obligations of the Clinic enforceable against the Clinic in accordance
with their respective terms, except as may be limited by applicable bankruptcy,
insolvency or similar laws affecting creditors' rights generally or the
availability of equitable remedies.  The execution and delivery of the Service
Agreement, the Physician Employment Agreements and the other agreements
contemplated hereby will not violate any provision of the organizational
documents of the Clinic or any provisions of, or result in the acceleration of,
any obligation under any mortgage, lien, lease, agreement, rent, instrument,
order, arbitration award, judgment or decree to which the Clinic is a party or
by which the Clinic is bound, or violate any material restrictions of any kind
to which the Clinic is subject, or result in any lien or encumbrance on any of
the Clinic's assets.

         4.4     NO BUSINESS.  The Clinic has not commenced business since its
organization.  Other than its Articles of Incorporation, Bylaws and as of the
Closing Date, the Service Agreement and the Physician Employment Agreements,
the Clinic is not a party to or subject to any agreement, indenture or other
instrument.  The Clinic does not own any assets (tangible or intangible) other
than (i) the assets described on Exhibit 4.4 attached hereto, and (ii) the

consideration received upon the issuance of shares of its capital stock, and
the Clinic does not have any liabilities, accrued, contingent or otherwise
(known or unknown and asserted or unasserted).

applicable laws, regulations and licensing requirements and has filed with the
proper authorities all necessary statements and reports.

<PAGE>   24
OR THE OTHER DOCUMENTS TO BE EXECUTED IN CONNECTION HEREWITH, OR.

         (VIII)  ANY ACCRUED UNFUNDED RETIREMENT OR PENSION PLAN LIABILITIES.

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.

         11.4    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.

         11.5    LIMITATION ON INDEMNIFICATION.  Notwithstanding anything
contained herein to the contrary, any indemnification by the Company and
Shareholders in favor of PRG or PRG Sub shall not exceed in all cases the
Escrowed Shares, and any indemnification by PRG and PRG Sub in favor of the
Company and Shareholders shall not exceed in all cases the Escrowed Shares.
Furthermore, no claim for Damages shall be made by any party more than one (1)
year after the Closing Date.

         11.6    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
Corporation covering taxable periods ending on or before the Closing Date which
have not been filed on or before the Closing Date.  Shareholders 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 Corporation for all taxes (excluding, however, income taxes of the
Company and the tax liabilities, if any, disclosed on the Financial
Statements), 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"). Shareholders 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 Corporation for all Taxes for any Straddle





                                       23
<PAGE>   25
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, 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 August 31, 1996; or

         (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.


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):





                                       24
<PAGE>   26
                 (a)      except as set forth on Exhibit 13.1(a),  attached
hereto, 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 by PRG, PRG Sub, Surviving Corporation or any
practice managed by PRG or any subsidiary of PRG anywhere within, as of the
Closing Date, (i) 25 miles of any location of the Clinic, the practices set
forth on Exhibit 13.1(a), and any ophthalmology practice managed by PRG or any
subsidiary of PRG located outside of a Standard Statistical Metropolitan Area
having a population of greater than 1,000,000, or (ii) 10 miles of any location
of any ophthalmology practice managed by PRG or any subsidiary of PRG located
within a Standard Statistical Metropolitan Area having a population of greater
than 1,000,000; provided, however, that this provision shall not prohibit (a)
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) a Shareholder from performing surgery at any hospital or outpatient
surgical facility which provides services similar to those provided by the
Clinic, PRG or any of its Affiliates; 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 on Schedule 13.2.

         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 are not consummated for any
reason but otherwise shall not be affected by any breach of any other provision
hereof by any party hereto.  The covenants contained in this Section 13 shall
terminate in the event the Service Agreement is terminated pursuant to Section
3.11 or Section 9.3 thereto.

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    AFFILIATES.  PRG shall be entitled to place legends as
specified in the Affiliates Letters on the certificate(s) evidencing any common

provided, however, that PRG Sub, Surviving Corporation and PRG may assign its
rights and obligations hereunder to an affiliate and to their lender or
lenders.

         16.11   NO RULE OF CONSTRUCTION.  The parties acknowledge that this
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
rule of construction shall apply to this Agreement which construes ambiguous
language in favor of or against any party by reason of that party's role in
drafting this Agreement.

         16.12   COSTS OF ENFORCEMENT. In the event that PRG Sub, Surviving
Corporation or PRG, on the one hand, or the Company or the Shareholders, on the
other hand, file suit in any court against any other party to enforce the terms
of this Agreement against the other party or to obtain performance by it
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.

         16.13   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
signed by the parties hereto.  The waiver of any of the terms and conditions of
this Agreement shall not be construed as a waiver of any other terms and
conditions hereof.

         16.14   CHOICE OF FORUM.  Each of the parties hereto agree that should
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.

         16.15   SERVICE OF PROCESS.  Service of any and all process that may
be served on any party hereto in any suit, action or proceeding arising out of
this Agreement may be made in the manner and to the address set forth in
Section 16.1 and service thus made shall be taken and held to be valid personal
service upon such party by any party hereto on whose behalf such service is
made.

         16.16   SEVERABILITY.  If any provision of this Agreement shall be
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.

         16.17   ARBITRATION.  Except for matters for which an injunction,
restraining order, writ of mandamus, specific





                                       28

performance or other equitable relief may be sought by a party hereunder, any
disputes between the parties arising out of or otherwise relating to this
Agreement (whether based in contract, tort, or other legal theory), shall be
resolved by and through an arbitration proceeding to be conducted under the
auspices of the American Arbitration Association (or any like organization
successor thereto) in Dallas, Texas.  Such arbitration proceeding shall be
conducted in as expedited a manner as is then permitted by the commercial
arbitration rules (formal or informal) of the American Arbitration Association,
and the arbitrator or arbitrators in any such arbitration shall be persons who
are expert in the subject matter of the dispute.  Both the foregoing agreement
of the parties to arbitrate any and all such claims, and the results,
determination, finding, judgment and/or award rendered through such
Arbitration, shall be final and binding on the parties hereto and may be
specifically enforced by legal proceedings, and the parties agree that a
judgment of any court of competent jurisdiction may be rendered upon any
arbitration rendered pursuant to this Section.  Such arbitration may be
initiated by written notice from any party to the others which shall be a
compulsory and binding proceeding on each party.  The arbitration shall be
conducted before a panel of arbitrators selected in accordance with the rules
of the American Arbitration Association.  The costs of the arbitrators and the
arbitration, including the cost of their respective attorneys, witnesses and
experts in connection with such arbitration, incurred by the prevailing party
in the arbitration shall be paid by the other parties thereto.  Time is of the
essence of this arbitration procedure, and the arbitrators shall be instructed
and required to render their decision within ten (10) days following completion
of the arbitration.  Any and all legal proceedings to enforce this Agreement
(including any action to compel arbitration hereunder or to enforce any award
or judgment rendered thereby) shall be governed in accordance with this
Section.

         16.18   GOOD FAITH.  The parties agree to act in good faith and
reasonably with respect to the exercise of their respective rights, duties and
obligations .

("PRG Sub"); PHYSICIANS RESOURCE GROUP, INC., a Delaware corporation ("PRG");
LEWIS LAURING, M.D., P.A., a Florida professional corporation (the Company"),
and  LEWIS LAURING, M.D.,  an individual resident of the State of Florida (the
"Shareholder").





                                  WITNESSETH:

         WHEREAS, the Company operates an ophthalmology practice in Tampa, 
Florida;

         WHEREAS, Shareholders are the only shareholders of the Company;

         WHEREAS, PRG Sub is engaged in the business of acquiring the assets of
and operating 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"), and for
financial accounting purposes 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 Sub with and into the Company shall occur on the
31st day of August, 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 SUB INTO THE COMPANY.  On the Closing Date, PRG
Sub shall be merged with and into the Company in accordance with this Agreement

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 Florida Business Corporation Law.

<PAGE>   3
         1.2     MERGER CERTIFICATES.  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 shall cause to be properly executed and filed on the Closing
Date Articles of Merger meeting the requirements of the Florida Business
Corporation Law.  The Merger shall become effective on the Closing Date.

         1.3     CERTIFICATE OF INCORPORATION OF SURVIVING CORPORATION.
Effective on the Closing Date, the Certificate of Incorporation of PRG Sub
shall be the Articles of Incorporation of the Surviving Corporation and to the
extent the foregoing is not permitted by law, the Articles of Incorporation of
the Surviving Corporation shall be the Articles of Incorporation of the Company
and shall immediately be amended to contain the terms and provisions of the
Articles of Incorporation of PRG Sub.

         1.4     BYLAWS OF THE SURVIVING CORPORATION.  The Bylaws of PRG Sub on
the Closing Date shall be the Bylaws of the Surviving Corporation, until duly
amended in accordance with their terms.

         1.5     DIRECTORS OF THE SURVIVING CORPORATION.  The persons who are
directors of PRG Sub immediately prior to the Closing Date shall, from and

         1.6     OFFICERS OF THE SURVIVING CORPORATION.  The persons who are
officers of PRG Sub immediately prior to the Closing Date shall, from and after
the Closing Date, be the officers of the Surviving Corporation and shall hold

         1.7     CONVERSION OF COMPANY COMMON STOCK.  The manner of converting
shares of the Company 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 shares of Company common stock issued and
outstanding 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 fully registered 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 shares of the Company shall cease to be outstanding
and shall be cancelled and retired and shall cease to exist, and each holder of
a certificate representing any such shares of Company common stock shall
thereafter cease to have any rights with respect to such shares of Company
common stock, except the right to receive, without interest, the Merger
Consideration.

                 (b)      Each share of Company common stock held in the
Company's treasury, if any, on the Closing Date, by virtue of the Merger, shall
cease to be outstanding and shall be cancelled and retired without payment of
any consideration therefor and shall cease to exist.

                 (c)      On the Closing Date, each share of PRG Sub common
stock issued and outstanding as of the Closing Date shall be surrendered in
exchange for a share of validly issued, fully paid and nonassessable share of
common stock of Surviving Corporation.

         1.8     EXCHANGE OF CERTIFICATES REPRESENTING SHARES OF COMPANY COMMON
STOCK.

                 (a)      At or after the Closing Date, (i) the Shareholders,
as the holders of all outstanding certificates representing shares of Company
common stock, shall, upon surrender of such certificates, be entitled to
receive the Merger Consideration and (ii) until the certificates representing
Company common stock have been surrendered by Shareholders and replaced by
certificates representing PRG common stock, the certificates for Company common
stock shall, for all purposes, be deemed to evidence ownership of PRG common
stock.

Date the certificates representing Company common stock owned by them, duly
endorsed in blank by the Shareholders, or accompanied by blank stock powers and
with all necessary transfer tax and other revenue stamps, acquired at the
Shareholders' expense, affixed and cancelled.  The Shareholders agree to cure
any deficiencies with respect to the endorsement of the certificates or other
documents of conveyance with respect to such Company common stock or with
respect to the stock powers accompanying any Company Common Stock.  Upon such
delivery, the Shareholder shall be entitled to receive in exchange therefor a
certificate representing that number of shares of PRG common stock Shareholder
is entitled to receive pursuant to Section 1.7.

                 (c)      Notwithstanding Section 1.7 or any other provision of
this Section 1.8, no fractional shares of PRG common stock will be issued.

         1.9     ESCROW.  In addition to the shares issuable to the
Shareholders at Closing, PRG shall deposit in escrow the number of shares of

terms of an Escrow Agreement (the "Escrow Agreement") in the form attached
hereto as Exhibit 1.9, to be entered into among Shareholders, the Company, PRG
Sub, PRG and Jackson &Walker, L.L.P. , 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 Sub may be entitled to indemnification
pursuant to Article XI in accordance with the terms of the Escrow Agreement.

         1.10    SUBSEQUENT ACTIONS. If, at any time after the Closing Date,
the Surviving Corporation 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
Corporation its right, title or interest in, to or under any of the rights,
properties or assets of the Company or PRG Sub acquired or to be acquired by

otherwise to carry out this Agreement, and to effect the cancellation of all
outstanding shares of Company common stock in return for the consideration set

         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 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
pending or in process, or to the knowledge of the Company and Shareholders,
threatened.  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    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,





                                       8
<PAGE>   10
and whether due or to become due, other than those incurred in the ordinary
course of business.  The Company and the Shareholders do not know, or have
reasonable grounds to know, of any basis for the assertion against the Company
as of the Balance Sheet Date, of any claim or liability of any nature in any
amount not fully reflected or reserved against on the Balance Sheet, or of any
claim or liability of any nature arising since that date other than those
incurred in the ordinary course of business or contemplated by this Agreement.
All indebtedness of the Company (including without limitation, indebtedness for
borrowed money, guaranties and capital lease obligations) is described on
Exhibit 2.18 attached hereto.

         2.19    INSURANCE POLICIES.  The Company, each Shareholder and each
physician employee of the Company carries property, liability, malpractice,
workers' compensation and such other types of insurance as is customary in the
industry.  Valid 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 2.19 attached hereto and true and correct
copies have been delivered to PRG Sub.  Neither the Company nor any Shareholder
has received notice or other communication from the issuer of any such
insurance policy cancelling or amending such policy or threatening to do so.
Neither the Company, nor each Shareholder nor any physician employee of the
Company has any outstanding claims, settlements or premiums owed against any
insurance policy.

         2.20    EMPLOYEE BENEFIT PLANS.  Except as set forth on Exhibit 2.20
attached hereto, the Company has neither established, nor maintains, nor is
obligated to make contributions to or under or otherwise participate in, (a)
any bonus or other type of compensation or employment plan, program, agreement,
policy, commitment, contract or arrangement (whether or not set forth in a
written document); (b) any pension, profit-sharing, retirement or other plan,
program or arrangement; or (c) any other employee benefit plan, fund or
program, including, but not limited to, those described in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA").  All
such plans listed on Exhibit 2.20 (individually "Company Plan," and
collectively "Company Plans") have been operated and administered in all
material respects in accordance with all applicable laws, rules and
regulations, including without limitation, ERISA, the Internal Revenue Code of
1986, as amended, Title VII of the Civil Rights Act of 1964, as amended, the
Equal Pay Act of 1967, as amended, the Age Discrimination in Employment Act of
1967, as amended, and the related rules and regulations adopted by those
federal agencies responsible for the administration of such laws.  No act or
failure to act by the Company has resulted in a "prohibited transaction" (as
defined in ERISA) with respect to the Company Plans.  No "reportable event" (as
defined in ERISA) has occurred with respect to any of the Company Plans.  The
Company has not previously made, is not currently making, and is not obligated
in any way to make, any contributions to any multiemployer plan within the
meaning of the Multi-Employer Pension Plan Amendments Act of 1980.  With
respect to each Company Plan, either (i) the value of plan assets (including
commitments under insurance contracts) is at least equal to the value of plan
liabilities or (ii) the value of plan liabilities in excess of plan assets is
disclosed on the Balance Sheet, all as of the Closing Date.

         2.21    ADVERSE AGREEMENTS.  The Company is not, and will not be as of
the Closing Date, a party to any agreement or instrument or subject to any
charter or other corporate 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 Company.

         2.22    COMPLIANCE WITH LAWS IN GENERAL.  The Company, the
Shareholders and Company's physician and licensed employees 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 Americans with Disabilities Act and any
environmental laws and medical waste laws, and there exist no violations by the
Company, any Shareholder or any physician or licensed employee of the Company
of any federal, state or local law or regulation.  Neither the Company nor any
Shareholder has received any notice of a violation of any federal, state and
local laws, regulations and ordinances relating to the operations of the
business and assets of the Company and no notice of any pending inspection or
violation of any such law, regulation or ordinance has been received by the
Company or any Shareholder.

         2.23    MEDICARE AND MEDICAID PROGRAMS.  The Company, each Shareholder
and each physician and

which are in full force and effect with no defaults having occurred thereunder.
The Company, each Shareholder and each physician and licensed employee of the
Company has timely filed all claims or other reports required to be filed with
respect to the purchase of services by third-party payors, and all such claims
or reports are complete and accurate, and has no liability to any payor with
respect thereto.  There are no pending appeals, overpayment determinations,
adjustments, challenges, audit, litigation or notices of intent to open
Medicare or Medicaid claim determinations or other reports required to be filed
by the Company, each Shareholder and each licensed employee of the Company.
Neither the Company, nor any Shareholder, nor any physician or licensed
employee of the Company has been convicted of, or pled guilty or nolo
contendere to, patient abuse or negligence, or any other Medicare or Medicaid
program related offense and none has committed any offense which may serve as
the basis for suspension or exclusion from the Medicare and Medicaid programs.

persons and entities providing professional services for the Company's business
have not, to the knowledge of the Company and the Shareholders, engaged in any

<PAGE>   24
OR THE OTHER DOCUMENTS TO BE EXECUTED IN CONNECTION HEREWITH, OR.

         (VIII)  ANY ACCRUED UNFUNDED RETIREMENT OR PENSION PLAN LIABILITIES.

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

         11.4    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.

         11.5    LIMITATION ON INDEMNIFICATION.  Notwithstanding anything
contained herein to the contrary, any indemnification by the Company and
Shareholders in favor of PRG or PRG Sub shall not exceed in all cases the
Escrowed Shares, and any indemnification by PRG and PRG Sub in favor of the
Company and Shareholders shall not exceed in all cases the Escrowed Shares.
Furthermore, no claim for Damages shall be made by any party more than one (1)
year after the Closing Date.

         11.6    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
Corporation covering taxable periods ending on or before the Closing Date which
have not been filed on or before the Closing Date.  Shareholders 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 Corporation for all taxes (excluding, however, income taxes of the
Company and the tax liabilities, if any, disclosed on the Financial
Statements), 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

Periods"). Shareholders 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 Corporation for all Taxes for any Straddle





                                       23
<PAGE>   25
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, 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.

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 on Schedule 13.2.

         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 are not consummated for any
reason but otherwise shall not be affected by any breach of any other provision
hereof by any party hereto.  The covenants contained in this Section 13 shall
terminate in the event the Service Agreement is terminated pursuant to Section
3.11 or Section 9.3 thereto.

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    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.

         16.9    COUNTERPARTS.  This Agreement may be executed in several
counterparts, each of which when so executed shall be deemed to be an original,
and such counterparts shall together constitute and be one and the same
instrument

         16.10   BINDING EFFECT/ASSIGNMENT.  This Agreement shall be binding
on, and shall inure to the benefit of, the parties hereto, and their respective
successors and assigns, and no other person shall acquire or have any right
under or by virtue of this Agreement.  No party may assign any right or
obligation hereunder without the prior written consent of the other parties;
provided, however, that PRG Sub, Surviving Corporation and PRG may assign its
rights and obligations hereunder to an affiliate and to their lender or
lenders.

         16.11   NO RULE OF CONSTRUCTION.  The parties acknowledge that this
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
rule of construction shall apply to this Agreement which construes ambiguous
language in favor of or against any party by reason of that party's role in
drafting this Agreement.

         16.12   COSTS OF ENFORCEMENT. In the event that PRG Sub, Surviving
Corporation or PRG, on the one hand, or the Company or the Shareholders, on the
other hand, file suit in any court against any other party to enforce the terms
of this Agreement against the other party or to obtain performance by it
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.

         16.13   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
signed by the parties hereto.  The waiver of any of the terms and conditions of
this Agreement shall not be construed as a waiver of any other terms and
conditions hereof.

         16.14   CHOICE OF FORUM.  Each of the parties hereto agree that should
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.

         16.15   SERVICE OF PROCESS.  Service of any and all process that may
be served on any party hereto in any suit, action or proceeding arising out of
this Agreement may be made in the manner and to the address set forth in
Section 16.1 and service thus made shall be taken and held to be valid personal
service upon such party by any party hereto on whose behalf such service is
made.

         16.16   SEVERABILITY.  If any provision of this Agreement shall be
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.

         16.17   ARBITRATION.  Except for matters for which an injunction,
restraining order, writ of mandamus, specific





                                       28
<PAGE>   30
performance or other equitable relief may be sought by a party hereunder, any
disputes between the parties arising out of or otherwise relating to this
Agreement (whether based in contract, tort, or other legal theory), shall be
resolved by and through an arbitration proceeding to be conducted under the
auspices of the American Arbitration Association (or any like organization
successor thereto) in Dallas, Texas.  Such arbitration proceeding shall be
conducted in as expedited a manner as is then permitted by the commercial
arbitration rules (formal or informal) of the American Arbitration Association,
and the arbitrator or arbitrators in any such arbitration shall be persons who
are expert in the subject matter of the dispute.  Both the foregoing agreement
of the parties to arbitrate any and all such claims, and the results,
determination, finding, judgment and/or award rendered through such
Arbitration, shall be final and binding on the parties hereto and may be
specifically enforced by legal proceedings, and the parties agree that a
judgment of any court of competent jurisdiction may be rendered upon any
arbitration rendered pursuant to this Section.  Such arbitration may be
initiated by written notice from any party to the others which shall be a
compulsory and binding proceeding on each party.  The arbitration shall be
conducted before a panel of arbitrators selected in accordance with the rules
of the American Arbitration Association.  The costs of the arbitrators and the
arbitration, including the cost of their respective attorneys, witnesses and
experts in connection with such arbitration, incurred by the prevailing party
in the arbitration shall be paid by the other parties thereto.  Time is of the
essence of this arbitration procedure, and the arbitrators shall be instructed
and required to render their decision within ten (10) days following completion
of the arbitration.  Any and all legal proceedings to enforce this Agreement
(including any action to compel arbitration hereunder or to enforce any award
or judgment rendered thereby) shall be governed in accordance with this
Section.

         16.18   GOOD FAITH.  The parties agree to act in good faith and
reasonably with respect to the exercise of their respective rights, duties and
obligations .

securities of Seller convertible into equity interests in Seller, or (c)
commitments, options, rights or warrants to issue any such equity interests in
Seller, to issue securities of Seller convertible into such equity interests,
or to redeem any securities of Seller.  No equity interests of Seller have been

Agreement and such related documents.  Each Member has the legal capacity to

to the consummation of the transactions contemplated herein.  This Agreement
and all agreements and documents executed and delivered in connection herewith

affecting creditors' rights generally or the availability of equitable
remedies.  The execution and delivery of this Agreement, and the agreements

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

Indemnified Person, be entitled to assume the defense of such action or
proceeding with counsel chosen by Indemnitor and reasonably satisfactory to

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.

<PAGE>   21
         (b)     at any time by PRG or PRG Sub if any representation or
warranty of Seller contained in this Agreement or in any certificate or other
document executed and delivered by Seller pursuant to this Agreement is or
becomes untrue or breached in any material respect or if Seller 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 Seller 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 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

         (d)     by PRG, PRG Sub or by Seller if the merger contemplated hereby
shall not have been consummated by August 31, 1996; or

         (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 Seller, that such termination is desirable and in

SECTION 11.      [INTENTIONALLY LEFT BLANK].



SECTION 12.      NONDISCLOSURE OF CONFIDENTIAL INFORMATION.  Seller recognizes
and acknowledges that it had in the past, currently have, and in the future may
possibly have, access to certain confidential information of PRG or PRG Sub
that is valuable, special and unique assets of PRG's or PRG Sub's businesses.
Seller agrees that it 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 Seller, (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), Seller
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) Seller reasonably believes that such disclosure is
required in connection with the defense of a lawsuit against the disclosing
party, or (iv) Seller 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 Seller of the
provisions of this Section 12, PRG or PRG Sub shall be entitled to an
injunction restraining Seller and from disclosing, in whole or in part, such
confidential information.  Nothing herein shall be construed as prohibiting PRG
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 12 shall survive the termination of this Agreement.


SECTION 13.      INVESTMENT REPRESENTATIONS.

         13.1    ECONOMIC RISK; SOPHISTICATION.  Seller 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 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.  Seller or its 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.  Seller or its purchaser representatives has asked
any and all questions in the nature described in the preceding sentence and all
questions have been answered to their satisfaction.

amount due PRG Sub shall be credited to the Acquisition Consideration.  Upon
payment by PRG Sub of such taxes actually assessed and paid on the Assets, PRG
Sub shall calculate the apportionment of such taxes and shall pay Seller or may
demand from Seller, and Seller agrees to pay, the amount necessary to correct
the estimate and proration made at Closing.
