ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         EQUIMED ACQUISITION

         Physicians Resource Group, Inc., a Delaware corporation ("PRG")
entered into an Asset Purchase Agreement (herein so called) among PRG, PRG
Georgia, Inc., a Delaware corporation ("PRG Sub") and EquiMed, Inc., a Delaware
corporation ("EquiMed"), pursuant to which PRG will acquire (through PRG Sub, a
wholly owned subsidiary of PRG) substantially all of the assets and properties
and certain liabilities related to EquiMed's ophthalmological physician
practice management business operating through its Ophthalmology Division (the
"Division").  The Asset Purchase Agreement was executed on October 7, 1996.

         To the best knowledge of PRG, at the time of the execution of the
Asset Purchase Agreement there was no material relationship between (i) EquiMed
and its stockholders, on the one hand and (ii) PRG or any PRG affiliates,
directors or officers or any associate of such directors or officers on the
other.

         The consideration for the acquisition was determined by arms-length
negotiations between the parties.  The aggregate consideration to be paid for
the purchase of the assets of the Division generally is $54,563,400 plus a
multiple of the amount of change that any additional acquisitions of
ophthalmological practices by EquiMed that are closed or are the subject of
binding purchase agreements on or before March 31, 1997 would have had on
EquiMed's net income for the year ended December 31, 1996, had such additional
acquisitions been consummated by EquiMed on January 1, 1996.  The primary
source of funds to be used for the acquisition of the assets of the Division by
PRG will be cash from PRG's working capital.

         As a result of the acquisition, PRG will become the indirect holder
(through PRG Sub) of substantially all of the assets and properties and certain
liabilities related to the business of the Division.  PRG intends to provide
the use of such assets to the various ophthalmological practices pursuant to
the terms of the respective management services agreements entered into between
such practices and EquiMed.  The transaction contemplated by the Asset Purchase
Agreement is expected to be consummated in November 1996 following termination
of applicable waiting periods under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended.

         AMERICAN OPHTHALMIC ACQUISITION

         PRG also entered into an Agreement and Plan of Merger among PRG, PRG
Acquisition Corporation, a Delaware corporation ("Merger Sub") and American
Ophthalmic Incorporated, a Florida corporation ("AOI") (the "Merger
Agreement"), pursuant to which AOI shall merge with and into Merger Sub (the
"Merger").  The Merger Agreement was executed on October 7, 1996.

         As a result of the Merger, AOI will become a wholly-owned subsidiary
of PRG and PRG will become the indirect owner of all of the assets and
properties, real and personal, tangible and intangible, and liabilities of AOI,
a management services organization that is in the business of




                                      2

acquiring the assets of ophthalmological and optometric practices and providing
such practices with the use of the assets it acquires as well as other
management services under the terms of service agreements entered into with
such practices.  PRG intends to continue to provide the use of the assets
acquired through the Merger to such practices.

         To the best knowledge of PRG, at the time of the execution of the
Merger Agreement there was no material relationship between (i) AOI and its
stockholders on the one hand and (ii) PRG, or any of its affiliates, any
director or officer of PRG, or any associate of such director or officer on the
other.

         The aggregate consideration to be paid by PRG in connection with the
Merger (the "Merger Consideration") is expected to be $70,000,000.  Up to
$10,000,000 of the Merger Consideration may be placed into escrow for a period
of 135 days following Closing pending the provision by AOI of binding letters
of intent meeting certain specific acquisition criteria.  Half of the Merger
Consideration will be payable in cash and the remaining half of the Merger
Consideration will be payable in shares of the common stock, par value $.01 per
share, of PRG. The cash portion of the Merger Consideration shall be paid out
of PRG's working capital. The acquisition consideration for the Merger was
determined by arms-length negotiations between the parties to the Merger
Agreement.

         This ASSET PURCHASE AGREEMENT (this "Agreement"), made and executed as
of the 6th day of October, 1996, is by and among PRG GEORGIA, INC., a Delaware
corporation ("Purchaser"), PHYSICIANS RESOURCE GROUP, INC., a Delaware
corporation ("PRG") and EQUIMED, INC., a Delaware corporation ("Seller").
References contained herein to "Seller" and "Seller Sub" when used in the
context of description of the Business (hereinafter defined) or the Division
(hereinafter defined) shall be deemed to refer only to the ophthalmology
physician practice management and ambulatory surgery center business of Seller
and not to the oncology and other non-ophthalmology physician practice
management business of Seller.


                                  WITNESSETH:


         WHEREAS, Seller operates an ophthalmological physician practice
management business ("the Business") through its Ophthalmology Division (the
"Division");

         WHEREAS, Purchaser is a wholly-owned subsidiary of PRG, which is
engaged in the ophthalmological physician practice management business; and

         WHEREAS, Seller wishes to sell to Purchaser and Purchaser wishes to
acquire from Seller, substantially all of the assets used by the Division, all
upon the terms and subject to the 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:

SECTION 1.       DEFINITIONS.  As used in this Agreement, the following terms
shall have the meanings set forth below:

         (a)     "AAA" shall have the meaning set forth in Section 14.8.

         (b)     "Acquisition" shall mean the consummation of the transactions
contemplated by this Agreement.

         (c)     "Acquisition Pro Forma Net Income" shall mean the aggregate
amount of change determined on an accrual basis and with certain pro forma
adjustments that the Additional Acquisitions would have had on Purchaser's net
income for the year ended December 31, 1996 had the Additional Acquisitions
been consummated by Purchaser on January 1, 1996.  Acquisition Pro Forma Net
Income will include pro forma adjustments for (i) the effect on Purchaser's net
income for the year ended December 31, 1996 of amortization expense
attributable to the intangible assets created by acquiring the Additional
Acquisitions, (ii) an eight percent (8%) per annum pre-tax financing charge
applied to the dollar value of consideration paid in the acquisition of the
Additional Acquisitions, (iii) income taxes at the rate of 40% (assuming no
non-recurring tax benefits), and (iv) amortization expense related to the
direct expenses incurred by Purchaser in connection with consummation of the
Additional Acquisitions, including expenses for operational, accounting, legal
and Medicare compliance due diligence and related travel, but excluding any
general and administrative corporate expenses (including salary) of Purchaser,
all as if the Additional Acquisitions had been consummated on January 1, 1996,
as well as the other pro forma adjustments set forth on Exhibit 1(c) attached
hereto.  Acquisition Pro Forma Net Income shall be calculated by Purchaser in
accordance with work prepared by Arthur Andersen as reviewed and approved by
Ernst & Young using Purchaser's accounting methods, estimated useful lives, and
policies and in accordance with GAAP, consistently applied, and application of
the pro forma adjustments discussed above.





                                       1

         Within 30 days of the consummation of each Additional Acquisition, PRG
shall deliver to Seller in writing, PRG's calculation of Acquisition Pro Forma
Net Income related to such Additional Acquisition.  If Seller objects to PRG's
calculation of Acquisition Pro Forma Net Income, it shall so inform PRG in
writing (a "Dispute Notice") within five days of receipt by Seller of PRG's
calculation. In the absence of such Dispute Notice PRG's calculation shall be
final and binding on each party to this Agreement.  If a Dispute Notice is
delivered to PRG, Purchaser and Seller shall negotiate in good faith to resolve
any differences related to the calculation of Acquisition Pro Forma Net Income
promptly following delivery of the Dispute Notice.  If Purchaser and Seller
fail to reach agreement after three business days of such good faith
negotiations, then Acquisition Pro Forma Net Income shall be determined by a
partner in the Tampa, Florida office of Coopers & Lybrand, L.L.P. with
significant health care experience (the "Determining Party"), whose
determination of Acquisition Pro Forma Net Income shall be final and binding on
each party hereto.  In the event that it is necessary for the Determining Party
to calculate Acquisition Pro Forma Net Income, Purchaser and Seller will fully
cooperate with the Determining Party in order to enable the Determining Party
to reach its determination as soon as practicable, but in no event later than
15 days after the matter is referred to the Determining Party.  The cost of
retaining the Determining Party will be shared equally by Purchaser and Seller.

         (d)     "Acquisition Proposal" shall have the meaning set forth in
Section 5.5.

         (e)     "Acquisition Valuation" shall mean the product obtained by
multiplying (i) Acquisition Pro Forma Net Income times (ii) 12.

         (f)     "Accounts Payable" shall have the meaning set forth in Section
3.16.

         (g)     "Accounts Receivable" shall have the meaning set forth in
Section 3.16.

         (h)     "Additional Acquisitions" shall mean those acquisitions listed
on Exhibit 1(h) attached hereto, that, (i) on or prior to March 31, 1997, are
the subject of binding acquisition agreements with no material right of
termination on the part of the entity to be acquired and that are consummated
by the Division or by Purchaser or another wholly-owned subsidiary of PRG by
April 30, 1997 using the forms of acquisition agreements and service agreements
provided by Purchaser attached hereto as Exhibits 1(h)(i) and 1(h)(ii) with
such modifications as are reasonably necessary to consummate the acquisition
including a service fee containing the following components:  (1) a management
fee of 5% of net revenues, (2) an annual amortization charge equal to the
purchase price of the entity amortized over 18 years, (3) a net income fee
equal to maximum 51% of the net income of the practice calculated after the
application of (1) and (2), and such other modifications as are approved in
writing by Purchaser in advance of consummation of the Additional Acquisition,
which approval will not be unreasonably withheld, (ii) provide for a minimum of
fifty percent of the consideration for such Additional Acquisition in the form
of PRG Common Stock, the issuance of which is unregistered or which is
contractually restricted as to resale in accordance with the provisions of Rule
144 under the Securities Act of 1933, (iii) provide for a purchase price not to
exceed 10 times Annual After-Tax Contribution, with such variations in such
financial terms as may be consented to in writing by Purchaser in advance of
the consummation of the Additional Acquisition, (iv) comply with PRG's
financial, operational and legal due diligence standards as historically
applied (which the parties acknowledge include an audit by an independent
Medicare/Medicaid consultant) and (v) with respect to geographic markets in
which PRG or one of its subsidiaries currently manages an optometric or
ophthalmological practice or manages an ASC, the PRG-affiliated practices and
managed ASC's in that geographic market have approved the Additional
Acquisition.  The transaction referred to in the definition of CEC
Reimbursement shall be deemed to be an Additional Acquisition.

date of this Agreement, directly, or indirectly through one or more
intermediaries, controls, controlled, is controlled by, was controlled by, is

the laws of each jurisdiction in which the character of the properties owned or

Subs are entities duly organized, validly existing and in good standing under

         3.2     POWER AND AUTHORITY FOR TRANSACTIONS.  Seller 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

necessary action to approve 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 Seller, and constitute or will constitute the legal,
valid and binding obligation of Seller, enforceable against Seller 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 3.5, the consummation of the
actions contemplated hereby will not, violate any provision of the Certificate
of Incorporation or Bylaws of Seller 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 Seller
is a party or by





                                       8
<PAGE>   14
which Seller is bound, or violate any material restrictions of any kind to
which Seller is subject, or result in any lien or encumbrance on any of
Seller's assets.

         3.3     PERMITS, LICENSES AND GOVERNMENTAL AUTHORIZATIONS.  All
building or other permits, certificates of occupancy, concessions, grants,

modification, of any thereof.

to true and correct copies of the Certificate of Incorporation, Bylaws and
minutes of Seller and the Seller Subs (or, in the case of the Seller Subs that
are partnerships or limited liability companies, their organizational
documents) and all amendments thereto have been delivered to Purchaser.  The
minute books of Seller and Seller Subs that are corporations contain accurate
copies of all minutes of the meetings of and consents to actions taken without
meetings of the Board of Directors and stockholders of Seller since its
formation.  The books of account of Seller and the Seller Subs have been kept
accurately in the ordinary course of business and the revenues, expenses,
assets and liabilities of Seller and the Seller Subs have been properly
recorded in such books.

         3.5     CONSENTS.  Except as set forth on Exhibit 3.5, no consent,
approval, authorization, order, permit, license, filing or registration with

leases pursuant to which Seller or a Seller Sub leases, as lessor or lessee,
real or personal property that provide for payments to or by Seller or any of
the Seller Subs of an amount in excess of $25,000 per annum (which are not
cancelable on 30 days' notice) used in operating the Business or related to the
Assets and which are not cancelable on 30 days' notice.  All such leases listed
on Exhibit 3.7 are valid and enforceable in accordance with their respective
terms, and there is not under any such lease any existing default by Seller or
the Seller Subs, as lessor or lessee, or any condition or event of which Seller
has knowledge which with notice or lapse of time, or both, would constitute a
default, in respect of which Seller or the Seller Subs have not taken adequate
steps to cure such default or to prevent a default from occurring.

         3.8     CONDITION AND USEFULNESS OF ASSETS.  The Assets constitute the
only assets necessary for the conduct of the Business.  Seller has not made use

past operations of Seller or the Seller Subs in connection with the Assets
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.  Seller has the sole and exclusive right to use all

employees relating to the Business have no intention to and have not threatened
to organize or join a union, labor organization or collective bargaining unit,
and there are no existing or threatened labor strikes, disputes, grievances,

         3.14    CONTRACTS.  Seller has provided to Purchaser access to true

Business, all of which are listed or incorporated by reference on Exhibit 3.7

indicated on such Exhibits, all of such Contracts are valid, binding and

and no defenses, offsets or counterclaims have been asserted or may be made by
any party thereto.  Except as indicated on such Exhibits, there is not under

                 (l)      Experienced damage, destruction or loss (whether or

properties, assets or business or the Business or the Assets, or experienced
any other material adverse change in its financial condition, assets,
prospects, liabilities or business;

<PAGE>   18
                 (o)      Collected accounts receivable in a manner outside the
ordinary course of business or not consistent with past practice;

                 (p)      Suffered or caused to be suffered, or taken any
action that may result in, any material adverse change in the Business or to
the Assets; or

                 (q)      Effected any material change in Seller's respective
accounting principles, practices or methods as they relate to the Business or
the Division.

         3.16    ACCOUNTS RECEIVABLE/PAYABLE. The Balance Sheet reflects the
amount, as of the Balance Sheet Date and determined in conformity with GAAP and
the past practices employed by Seller, of the Division'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 3.16 contains a true and accurate (i) summary list of all
Accounts Receivable, (ii) summary list of all Accounts Payable and (iii)
statement of the working capital of the Division as of the Balance Sheet Date.
The Division maintains its accounting records in sufficient detail to
substantiate the accounts receivable reflected on the Balance Sheet and has
given and will give to Purchaser full and complete access to those records,
including the right to make copies therefrom.  Since the Balance Sheet Date,
neither Seller nor the Division has 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.  Seller is in
substantial compliance with the terms and conditions of such third-party payor
arrangements, and the reserves established by Seller are adequate to cover any
liability resulting from lack of compliance.

         3.17    TAXES.

                 (a)      RETURNS; PAYMENT OF TAXES.  All Tax Returns required
to have been filed by Seller, with respect to the Business of the Division, or
the Seller Subs have been timely filed (taking into account duly granted
extensions) and are true, correct and complete in all respects.  All Taxes
shown thereon as owing have been paid.  The Seller Subs and, to the extent
attributable to the Business of the Division, Seller, have withheld and paid
over all Taxes required to have been withheld and paid over and has complied
with all information reporting and back-up withholding requirements relating
thereto.  There are no liens with respect to Taxes on any of the Assets, other
than liens for Taxes not yet due and payable or for Taxes disclosed in Exhibit
3.17(a) that are being contested in good faith through appropriate proceedings
and for which adequate reserves have been established in the Financial
Statements.

                 (b)      DEFICIENCIES, PROCEEDINGS, WAIVERS.  No deficiencies
exist or have been asserted or, to the best knowledge of Seller, are expected
to be asserted (verbally or in writing) with respect to Taxes of the Seller
Subs or Seller attributable to the Business of the Division and Seller and the
Seller Subs have not received notice (verbally or in writing) that any of them
have not filed a Tax Return or paid any Taxes (attributable to the Business of
the Division, in the case of Seller) required to be filed or paid by it.  No
audit, examination, investigation, action, suit, claim or proceeding relating
to the determination, assessment or collection of any Tax of any Seller Sub or
of Seller attributable to the Business of the Division is currently in process,
pending or, to the best knowledge of Seller, threatened (verbally or in
writing).

                 (c)      SPECIAL STATUS.  The Contracts do not and will not
include any obligation to make any payment that under any circumstance will not
be deductible by Purchaser or any successor or assignee of Purchaser by reason
of Code Section 280G.  Except as disclosed in Exhibit 3.17(c), none of the
Assets and Contracts reflect any arrangement for which partnership Tax Returns
are required to be filed. None of the Assets are subject to any "safe harbor
lease" within the meaning of Code Section 168(f)(8) as in effect prior to
amendment by the Tax Equity and Fiscal Responsibility Act of 1982, or
constitute "tax-exempt use property" within the meaning of Code Section 168(h)
or "tax exempt bond financed property" within the meaning of Code Section
168(g)(5).

         3.18    LIABILITIES; DEBT.  Except to the extent reflected or reserved
against on the Balance Sheet, Seller and the Seller Subs did not have, as of
the Balance Sheet Date, and have not incurred since that date and will not have
incurred as of the Closing Date, any liabilities or obligations of any nature
(related to the Division, in the case of Seller), whether accrued, absolute,
contingent or otherwise, and whether due or to become due, other than those
incurred in the ordinary course of business.  Seller does not know, or have
reasonable grounds to know, of any basis for the assertion against Seller or
any of the Seller Subs, as of the Balance Sheet Date, of any claim or liability
of any nature (related to the Division, in the case of Seller) in any amount
not fully reflected or reserved against on the Balance Sheet, or of any claim
or liability of any nature (related to the Division, in the case of Seller)
arising since that date other than those incurred in the ordinary course of
business or contemplated by this Agreement.  All indebtedness of the Seller
Subs and of Seller related to the Division (including without limitation,
indebtedness for borrowed money, guaranties and capital lease obligations) is
described on Exhibit 3.18 attached hereto.

         3.19    INSURANCE.

                 (a)      Seller has property, fire and casualty insurance
policies, with extended coverage (subject to reasonable deductibles),
sufficient to allow Seller to replace any of its properties relating to the
Business that might be damaged or destroyed.  Except for professional liability
insurance which is specifically covered in Section 3.19(b) below, Seller, the
Practices and the ASC's have liability, workers compensation insurance and bond
and surety arrangements reasonably adequate, in light of the business in which
they are engaged, to protect them and their financial condition against the
risks involved in the business conducted by them.  Exhibit 3.19(b) sets forth a
list of all such policies as of the date thereof.

                 (b)      Exhibit 3.19(b) sets forth a list of each policy of
professional liability insurance and errors and omissions insurance, and all
amendments and endorsements thereto currently in effect, which provide
insurance for any of the Division, the Practices, the ASC's and the Additional
Acquisitions, including the name of each insurer, the amount of coverage
provided under the policy, all persons, groups and entities that are afforded
coverage under the policies, the term of the policy and type of coverage
(whether "claims made" or otherwise and whether such policies include "tail"
coverage) and whether the policy is in effect as of the date hereof.

                 (c)      Exhibit 3.19(c) sets forth any pending claims against
Seller under each of the policies described above, and there are no other
pending claims against Seller related to the Division, the Seller Subs, the
Practices and the ASC's under any of such policies, and to the knowledge of
Seller no event has occurred and no condition exists that could reasonably be
expected to give rise to or serve as a basis for any such claim.

                 (d)      Neither Seller nor any Seller Sub, Practice or ASC is
in default under any insurance policy or bond described in Sections 3.19(a) and
(b), and no event which would (with the passage of time, notice or both)
constitute a breach or default thereunder by Seller, any Seller Sub, any
Practice or any ASC or, to Seller's knowledge, the insurer thereunder, has
occurred, or, to Seller's knowledge, will occur as a result of the transactions
contemplated herein.  Consummation of the transactions contemplated herein will
not (and will not give any person or entity a right to) terminate or modify any
material rights of, or accelerate or augment any material obligation of Seller,
any Seller Sub, any Practice or any ASC under any insurance policy or bond
insofar as such policy or bond relates to or covers incidents that give rise to
claims for incidents taking place prior to the Closing Date.  Neither Seller,
any Seller Sub, any Practice nor any ASC has done anything by way of action or
inaction which might invalidate or diminish coverage under any of such policies
in whole or in part.  There are no outstanding requirements or recommendations
of any insurance company that has issued a policy to Seller, any Seller Sub,
any Practice or any ASC which require or recommend any changes to the conduct
of the business of Seller, any Seller Sub, any Practice or any ASC, or any
repair or other work with respect to any of its or their respective properties.

         3.20    EMPLOYEE BENEFIT PLANS.  Except as set forth on Exhibit 3.20
attached hereto and with respect to the employees of the Division, Seller 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





                                       14
<PAGE>   20
Employee Retirement Income Security Act of 1974, as amended ("ERISA").  All
such plans listed on Exhibit 3.20 (individually a "Seller Plan," and
collectively the "Seller Plans") have been operated and administered in all
material respects in accordance with all applicable laws, rules and
regulations, including without limitation, ERISA, the Code, 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 Seller has resulted
in a "prohibited transaction" (as defined in ERISA) with respect to the Seller
Plans.  No "reportable event" (as defined in ERISA) has occurred with respect
to any of the Seller Plans.  Seller has not previously made, is not currently
making, and is not obligated in any way to make, any contributions to any
multi-employer plan within the meaning of the Multi-Employer Pension Plan
Amendments Act of 1980.  With respect to each Seller 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.

         3.21    ADVERSE AGREEMENTS.  Neither Seller, any Seller Sub, any
Practice nor any ASC is, nor will 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, directly or indirectly, the
condition (financial or otherwise), operations, assets, liabilities, business
or prospects of the Division, the Business or the Assets.

         3.22    COMPLIANCE WITH LAWS IN GENERAL.  Seller, the Seller Subs, the
Practices and the ASC's hold all permits, licenses, variances, exemptions,
orders and approvals of all courts, administrative agencies or commissions or
other governmental authorities, instrumentalities or contractors, domestic or
foreign (each, a "Governmental Entity") necessary or advisable in the conduct
of the Business (or, in the case of the Seller Subs, the Practices, the ASC's
or their respective businesses) (the "Seller Permits").  Seller, the Seller
Subs, the Practices, the ASC's are in compliance with the terms of the Seller
Permits.  The Business (and, in the case of the Seller Subs, the Practices and,
the ASC's, their respective businesses) is not being conducted in violation of
any law, ordinance or regulation of any Governmental Entity, including, but not
limited to, laws, rules and regulations relating to professional and specialty
licensing, the corporate practice of medicine, prohibitions on kickbacks and
referrals under Medicare and Medicaid programs or under state law, health care,
drug enforcement, zoning ordinances, building codes, occupational health and
safety, employee benefits, immigration, wages, workplace safety, equal
employment opportunity and race, religious, sex and age discrimination.  No
investigation or review by any Governmental Entity with respect to Seller, any
of the Seller Subs, any of the Practices or the ASC's is pending, or, to the
knowledge of Seller, threatened, nor has any Governmental Entity indicated an
intention to conduct the same.

         3.23    MEDICARE AND MEDICAID PROGRAMS.  Each of the Practices and the
ASC's 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.  Each of the Practices, the
ASC's, the Seller Subs and Seller, as the case may be, 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 there is 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 any of the Practices,
the ASC's, the Seller Subs and Seller.  None of the Practices, the ASC's, the
Seller Subs and Seller have 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.

         3.24    FRAUD AND ABUSE.  None of the Practices or the ASC's (during
the time period in which any have been affiliated with Seller), the Seller Subs
and Seller have engaged in any activities which are prohibited under Section
1320a-7b or Section 1395nn of Title 42 of the United States Code or the
regulations promulgated thereunder, or related state or local statutes or
regulations, or which are prohibited by rules of professional conduct,
including, but not limited to, the following: (a) knowingly and willfully
making or causing to be made a false statement or representation of a material
fact in any application for any benefit or payment; (b) knowingly and willfully

for use in determining rights to any benefit or payment; (c) any failure by a
claimant to disclose knowledge of the occurrence of any event affecting the
initial or continued right to any benefit or payment on its own behalf or on
behalf of another, with the intent to fraudulently secure such benefit or
payment; and (d) knowingly and willfully soliciting or receiving any
remuneration (including any kickback, bribe or rebate) directly or indirectly,
overtly or covertly, in cash or in kind, or offering to pay or receive such
remuneration (i) in return for referring an individual to a person for the
furnishing or arranging for the furnishing of any item or service for which
payment may be made in whole or in part by Medicare or Medicaid, or (ii) in
return for purchasing, leasing or ordering or arranging for, or recommending,
purchasing, leasing or ordering any good, facility, service or item for which
payment may be made in whole or in part by Medicare or Medicaid, or (e)
referring a patient for designated health services to or providing designated

         10.1    NATURE AND SURVIVAL.  All statements contained in this
Agreement or in any Exhibit attached hereto, any agreement executed pursuant
hereto, and any certificate executed and delivered by any party pursuant to the
terms of this Agreement, shall constitute representations and warranties of
Seller, or of Purchaser, as the case may be.  All such representations and

this Agreement shall survive the date of this Agreement and the Closing Date
for a period of two (2) years following the Closing Date, except that the
representations and warranties set forth in Sections 3.17, 3.22, 3.23, 3.24,

Each party covenants with the other parties not to make any claim with respect
to such representations and warranties against any party after the date on
which such survival period shall terminate.  No party shall be entitled to

discharges the other party from any and all claims and demands, actions and
causes of action, damages, costs, expenses and rights of setoff with respect to
which the notices required by Section 10.2, 10.3 or 10.4, as applicable, are
not timely provided.

ARISING FROM OR BY REASON OF OR RESULTING FROM INDEMNITOR'S MANAGEMENT AND

         10.3    INDEMNIFICATION BY SELLER.  SELLER (FOR PURPOSES OF THIS
SECTION 10.3 AND, TO THE EXTENT APPLICABLE, SECTION 10.4, "INDEMNITOR"), SHALL
INDEMNIFY AND HOLD PURCHASER AND ITS OFFICERS, DIRECTORS, STOCKHOLDERS, AGENTS
AND EMPLOYEES (EACH OF THE FOREGOING, INCLUDING PURCHASER, FOR PURPOSES OF THIS
SECTION 10.3 AND, TO THE EXTENT APPLICABLE, SECTION 10.4, AS "INDEMNIFIED
PERSON") HARMLESS FROM AND AGAINST ANY AND ALL DAMAGES ARISING FROM OR BY
REASON OF OR RESULTING FROM ANY BREACH BY INDEMNITOR OF ANY REPRESENTATION,
WARRANTY, AGREEMENT OR COVENANT CONTAINED IN THIS AGREEMENT (INCLUDING THE
EXHIBITS HERETO) AND EACH DOCUMENT, CERTIFICATE, OR OTHER INSTRUMENT FURNISHED
OR TO BE FURNISHED BY INDEMNITOR HEREUNDER, AND, WITH RESPECT TO ALL TIMES
PRIOR TO OR AFTER THE CLOSING DATE, ARISING FROM OR BY REASON OF OR RESULTING
FROM THE INDEMNITOR'S MANAGEMENT AND CONDUCT OF THE OWNERSHIP OR OPERATION OF
THE BUSINESS OR THE ASSETS, AND WITH RESPECT TO (I) ANY VIOLATION BY SELLER OR
THEIR CONSULTANTS, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS AND AFFILIATES OF
STATE OR FEDERAL LAWS GOVERNING HEALTHCARE FRAUD AND ABUSE, OR ANY OVERPAYMENT
OR OBLIGATION ARISING OUT OF OR RESULTING FROM CLAIMS RELATED TO MEDICAL
TREATMENT OCCURRING ON OR PRIOR TO THE CLOSING DATE SUBMITTED TO ANY THIRD
PARTY PAYOR, WHETHER ON, PRIOR TO OR AFTER THE CLOSING DATE, ANY LIABILITIES
THAT ARE NOT SPECIFICALLY ASSUMED BY PURCHASER PURSUANT TO THE TERMS OF THIS
AGREEMENT AND ANY LIABILITIES NOT SET FORTH ON EXHIBIT 2.3(b) OR (II) ALL
LIABILITIES OF SELLER, IF ANY, FOR THE TAXES OF ANY OTHER PERSON PURSUANT TO
TREASURY REGULATIONS SECTION 1.1502-6 OR OTHER LAW, AS A TRANSFEREE OR
SUCCESSOR, BY CONTRACT OR OTHERWISE.

         10.4    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.

         10.5    RIGHT OF SETOFF.  In the event of any breach of warranty,
representation, covenant or agreement by Seller or any other event giving rise
to indemnification under Section 10.3 hereof, Purchaser shall be entitled to
offset the amount of damages incurred by it as a result of such breach of
warranty, representation, covenant or agreement against the amounts payable as
the Acquisition Valuation.  Purchaser shall notify Seller in writing in the
event that Purchaser claims a setoff with respect to such damages.  If Seller
objects to such setoff, in whole or in part, in writing within five (5)
business days following receipt of such notice of setoff claim and the disputed
claim is finally determined by arbitration or a court, as the case may be,
without any appeal of such determination having been filed within the
applicable period for appeal, then (A) Purchaser shall immediately pay to
Seller an amount equal to two (2) times the disputed amount of setoff taken by
Purchaser in the event that Seller is the prevailing





                                       25
<PAGE>   31
party and Purchaser has exercised its right to setoff hereunder and (B) Seller
shall immediately pay to Purchaser an amount equal to two (2) times the
disputed amount to which the court or arbitrator(s) has determined that
Purchaser is entitled in the event that Purchaser is the prevailing party and
has refrained from exercising its right to setoff hereunder following receipt
of objection to setoff until such time as the disputed claim is submitted for
determination and is determined by arbitration or litigation by any party
hereto.

         10.6    LIMITATION ON INDEMNIFICATION.  Notwithstanding any other
provision of this Section 10, in no event shall a person be entitled to
indemnification hereunder unless, and only to the extent that, the aggregate
amount of all Damages for which such person would otherwise be entitled to
indemnification exceeds in the aggregate (when considered together with other
persons similarly situated) one percent (1%) of the Closing Valuation.

SECTION 11.      TERMINATION.  This Agreement may be terminated:

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

         (b)     at any time by Purchaser 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 ten (10) days after receipt of written notice thereof; provided,
however, that in the case of a termination pursuant to this subsection,
Purchaser shall not have breached in any material respect its obligations under
this Agreement in any manner that shall have proximately contributed to the
occurrence of the failure referred to in this subsection;

         (c)     at any time by Seller if any representation or warranty of
Purchaser contained in this Agreement or in any certificate or other document
executed and delivered by Purchaser pursuant to this Agreement is or becomes
untrue or breached in any material respect or if Purchaser fails to comply in
any material respect with any covenant or agreement contained herein and such
misrepresentation, noncompliance or breach is not cured, waived or eliminated
within ten (10) days after receipt of written notice thereof; provided,
however, that in the case of a termination pursuant to this subsection, Seller
shall not have breached in any material respect its obligations under this
Agreement in any manner that shall have proximately contributed to the
occurrence of the failure referred to in this subsection;

         (d)     by either Purchaser or Seller if the transaction contemplated
hereby shall not have been consummated by November 30, 1996; provided that the
period set forth in this Section 11(d) shall automatically be extended until
such time as all applicable waiting periods under the HSR Act have expired; and
provided further that in the case of a termination pursuant to this subsection,
the terminating party shall not have breached in any material respect its
obligations under this Agreement in any manner; or

         (e)     by Purchaser at any time prior to November 6, 1996, if
Purchaser determines in its sole discretion as the result of its legal,
financial, environmental and operational due diligence with respect to Seller,
that such due diligence reveals a material adverse change or difference in the
financial condition of the Business from that reflected in the Financial
Statements or a material issue(s) with respect to the regulatory compliance of
the Division or the ophthalmological practices or ASC's managed or operated by
the Division.

SECTION 12.      NONCOMPETITION.

         12.1    PROHIBITED ACTIVITIES OF SELLER.  In order to protect
Purchaser and each of its affiliates (collectively, the "PRG Group") against
the unauthorized use or disclosure of any of their confidential information
presently known or hereinafter acquired by Seller and other good and valuable
consideration, Seller hereby agrees that, for a period of three (3) years
following the Closing Date, except as set forth on Exhibit 12.1 Seller and its
Affiliates shall not knowingly, directly or indirectly, for itself or on behalf
of any other corporation, person, firm,





                                       26
<PAGE>   32
partnership, association or any other entity (whether as an individual, agent,
employee, officer, director or in any other capacity):

                 (a)      engage or participate in or finance any business
which engages in direct competition with the ophthalmological or optometric
physician practice management business being conducted by PRG or any
ophthalmological or optometric practice or ophthalmological ambulatory surgical
center managed or operated by PRG or any member of the PRG Group anywhere
within 50 miles of any location of any member of the PRG Group or any
ophthalmological or optometric practice or ophthalmological ambulatory surgical
center managed or operated by PRG or any member of the PRG Group; provided,
however, that this provision shall not prohibit Seller or any of its Affiliates
from continuing to operate any existing facility that is not part of the
Business or Division or from purchasing or holding an aggregate equity interest
of up to 2%, so long as Seller and its Affiliates combined do not purchase or
hold an aggregate equity interest of more than 5%, in any business in direct
competition with the ophthalmological or optometric physician practice
management business of the PRG Group or any ophthalmological or optometric
practice managed by the PRG Group; or

                 (b)      induce or attempt to influence any employee of any
member of the PRG Group or any ophthalmological or optometric practice or
ophthalmological ambulatory surgical center managed or operated by PRG or any
member of the PRG Group 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.

         12.2    DAMAGES.  Because of the difficulty of measuring economic
losses as a result of the breach of the covenants set forth in Section 12.1 and
12.5, and because of the immediate and irreparable damage that would be caused
thereby for which the non-breaching party would have no other adequate remedy,
each party agrees that, in the event of a breach by it or any of its Affiliates
of the covenants set forth in Section 12.1 and 12.5, the covenants may be
enforced by the non-breaching party or parties by injunctions and restraining
orders.  The specific enforcement of the covenants set forth in Section 12.1
and 12.5 is nonexclusive and shall not preclude any party hereto from seeking
any other remedy available at law or in equity.

         12.3    REASONABLE RESTRAINT.  It is agreed by the parties that the
covenants in this Section 12 impose reasonable restraints on the parties hereto
in light of the activities and business of Seller, on the one hand, and
Purchaser and the PRG Group, on the other hand, on the date of the execution of
this Agreement and the future plans of Seller, on the one hand, and Purchaser,
on the other hand, and the PRG Group.

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

         12.5    PROHIBITED ACTIVITIES OF PURCHASER AND PRG.

                 (a)      In the event that the Acquisition is not consummated,
in order to protect Seller against unauthorized use of the information set
forth in Exhibit 1(h), Purchaser and PRG jointly and severally agree that for a
period of seven (7) months following the date of this Agreement, neither
Purchaser nor PRG will pursue or otherwise take action to acquire the practices
listed in Exhibit 1(h).

                 (b)      In the event that Seller presents to PRG a potential
acquisition that is a practice or ambulatory surgery center listed on Exhibit
1(h) and PRG declines to pursue the proposed acquisition because the financial
terms proposed by Seller do not fit the criteria for an Additional Acquisition,
then neither Purchaser nor PRG shall prior to November 30, 1997 consummate or
attempt to consummate an acquisition of the practice or ambulatory surgery
center that was the subject of the proposed acquisition on financial terms
substantially similar to those presented by Seller and declined by PRG.





                                       27
<PAGE>   33
         12.6    TERM.  It is specifically agreed that the time periods stated
in Sections 12.1 and 12.5 above shall be computed by excluding from such
computation any time during which Seller or any of its Affiliates is in
violation of any provision of this Section 12.  The covenants contained in this
Section 12 shall have no effect if the transactions contemplated by this
Agreement are not consummated for any reason but otherwise shall not be
affected by any breach of any other provision hereof by any party hereto.

SECTION 13.      NONDISCLOSURE OF CONFIDENTIAL INFORMATION.

                 (a)      Seller recognizes and acknowledges it had in the
past, currently has, and in the future may possibly have, access to certain
confidential information of the PRG Group that constitutes valuable, special
and unique assets of the PRG Group'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 Purchaser, 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 13, Purchaser shall be
entitled to an injunction restraining Seller from disclosing, in whole or in
part, such confidential information.  Nothing herein shall be construed as
prohibiting Purchaser from pursuing any other available remedy for such breach
or threatened breach, including the recovery of damages. The obligations of the
parties under this Section 13 shall survive the termination of this Agreement.

                 (b)      Purchaser recognizes and acknowledges it had in the
past, currently has, and in the future may possibly have, access to certain
confidential information of the Seller that constitutes valuable, special and
unique assets of Seller's businesses.  Purchaser 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 Purchaser, (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), Purchaser shall, if possible,
give prior written notice thereof to Seller, and provide such other parties
hereto with the opportunity to contest such disclosure, (iii) Purchaser
reasonably believes that such disclosure is required in connection with the
defense of a lawsuit against the disclosing party, or (iv) Purchaser 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 Purchaser of the provisions of this Section 13, Seller
shall be entitled to an injunction restraining Purchaser from disclosing, in
whole or in part, such confidential information.  Nothing herein shall be
construed as prohibiting Seller from pursuing any other available remedy for
such breach or threatened breach, including the recovery of damages. The
obligations of the parties under this Section 13 shall survive the termination
of this Agreement.

SECTION 14.      MISCELLANEOUS.

         14.1    ADDITIONAL ACQUISITIONS.  With respect to any Additional
Acquisitions that are consummated on or prior to the Closing Date, PRG shall
lend to Seller the funds necessary for Seller to consummate the Additional
Acquisition.  With respect to Additional Acquisitions in geographic areas in
which the Division currently conducts business, the loan shall be evidenced by
a promissory note that matures in 90 days and is secured by the assets acquired
and the service agreement (if applicable) entered into in connection with the
Additional Acquisition.  With respect to Additional Acquisitions in geographic
markets in which the Division does not currently conduct Business, the loan
shall be evidenced by a promissory note that matures in 90 days, is secured by
the assets acquired and the service agreement (if applicable) entered into in
connection with the Additional Acquisition and at PRG's option may be retired
by a conveyance to Purchaser of the assets securing the promissory note.

         14.2    DEFERRED COMPENSATION.

                 (a)      In the event that Salvitti P.A. makes a payment to
Dr. Salvitti (a "Salvitti Payment") pursuant to either Section 3.9 of that
certain Physician Employment Agreement dated April 1, 1996 between Salvitti
P.A. and Dr.  Salvitti (the "Salvitti Employment Agreement") or Section 3.9 of
the Salvitti Optional Employment Agreement, to the extent that for either of
the two succeeding twelve month periods beginning the first day of the month
following the date of the Salvitti Payment, the difference between the net
income of the Salvitti P.A. for such twelve month period and the net income of
Salvitti P.A. for the twelve month period ending the last day of the month
immediately preceding the date of the Salvitti Payment (such difference the
"Salvitti P.A. Differential) is less than 33% of the amount of the Salvitti
Payment, Seller shall pay to Salvitti P.A. (an intended third party beneficiary
of this Agreement) an amount equal to the difference between 33% of the amount
of the Salvitti Payment and the Salvitti P.A. Differential.  For each of such
two twelve month periods following the Salvitti Payment, in the event that the
Salvitti P.A. Differential is a negative number, Seller shall pay to Salvitti
P.A. 33% of the amount of the Salvitti Payment.

                 (b)      To the extent that future payments by the Practices
of deferred compensation obligations existing on the date of this Agreement
exceed $1,000,000 (excluding the Salvitti Payment), then with respect to each
such deferred compensation payment, to the extent that for either of the two
succeeding twelve month periods beginning the first day of the month following
the date of the deferred compensation payment, the difference between the net
income of the Practice making such deferred compensation payment (the "Paying
Practice") for such twelve month period and the net income of the Paying
Practice for the twelve month period ending the last day of the month
immediately preceding the date of the deferred compensation payment (the
"Paying Practice Differential") is less than 33% of the amount of such deferred
compensation payment, Seller shall pay the Paying Practice (an intended third
party beneficiary of this Agreement) an amount equal to the difference between
33% of the amount of the deferred compensation payment and the Paying Practice
Differential.  For each of such two succeeding twelve month periods following
the deferred compensation payment, in the event that the Paying P.A.
Differential is a negative number, Seller shall pay to the Paying P.A. 33% of
the amount of the deferred compensation payment.

         14.3    NOTICES.  Any communications required or desired to be given

All such communications shall be deemed to have been delivered on the date of
hand delivery or on the next business day following the deposit of such
communications, properly addressed and postage prepaid with the overnight
courier.

         14.4    FURTHER ASSURANCES.  Each party hereby agrees to perform any
further acts and to execute and deliver any documents which may be reasonably
necessary to carry out the provisions of Agreement.

         14.5    EACH PARTY TO BEAR COSTS.

                 (a)      Except as provided in Section 2.3(c) above and
subparagraphs (b) and (c) below, each of the parties to this Agreement shall
pay all of the costs and expenses incurred by such party in connection with the
transactions contemplated by this Agreement, whether or not such transactions
are consummated.  Without limiting the generality of the foregoing and whether
or not such liabilities may be deemed to have been incurred in the ordinary
course of business, Purchaser shall not be liable to or required to pay, either
directly or indirectly, any fees and expenses of legal counsel, accountants,
auditors or other persons or entities retained by Seller for services rendered
in connection with negotiating and closing the transactions contemplated by
this Agreement or the documents to be executed in connection herewith or the
costs and expenses incurred by Seller in connection with the consummation of
the Additional Acquisitions that are consummated prior to the Closing Date,
whether or not such costs or expenses are incurred before or after the Closing
Date.

                 (b)      Notwithstanding the foregoing, fees and expenses
incurred by Arthur Andersen and Ernst & Young in connection with the
determination of the Acquisition Valuation shall be shared equally by Purchaser
and Seller; provided that Seller shall not be liable for more than $100,000.00
in such fees and expenses.

                 (c)      In the event that this Agreement is terminated as a
result of an Acquisition Proposal being accepted by Seller, Seller will pay to
Purchaser a fee equal to all fees and expenses incurred by Purchaser in
connection with the transactions contemplated hereby, plus $1,800,000.00; which
amount shall be payable by wire transfer of same day funds; provided that no
fee shall be payable to Purchaser pursuant to this Section 14.5(c) unless and
until any person (other than Purchaser) and the Seller have entered into a
definitive agreement intended to consummate an Acquisition Proposal.  Seller
acknowledges that the agreements contained in this Section 14.5(c) are an
integral part of the transactions contemplated in this Agreement, and that,
without these agreements, Purchaser would not enter into this Agreement;
accordingly, if Seller fails to promptly pay the amount due pursuant to this
Section 14.5(c), and, in order to obtain such payment, Purchaser commences a
suit which results in a judgment against the Seller for the fee set forth in
this paragraph (c), the non-prevailing party shall pay to the prevailing party
its costs and expenses (including attorneys' fees) in connection with such
suit, together with interest on the amount of the fee at the prime rate of
NationsBank of Texas, N.A. in effect on the date such payment was required to
be made.

         14.6    PUBLIC DISCLOSURES.  Except as otherwise required by law, no
party to this Agreement shall make any public or other disclosure of this

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

         14.7    TRANSFER TAXES.  Each party to this Agreement shall be
responsible for payment of all of their respective sales, use, excise,
documentary, registration, stamp, stock transfer and other transfer Taxes and
fees (including any related interest, penalties or other additions to Tax)
(collectively, "Transfer Taxes") arising from the consummation of the
transactions contemplated by this Agreement, and for the costs and expenses
related to the filing of all required Tax Returns relating to such Transfer
Taxes.  The party regularly required by applicable law to file any such Tax
Return shall prepare the return and file the return and pay all Taxes required
in respect thereof.

         14.8    ARBITRATION.  The parties hereto shall submit to binding
arbitration by a board of three arbitrators any disputed question or
controversy arising under this Agreement or arising out of or relating to the
transaction contemplated by this Agreement.  Any such arbitration shall be
conducted in Wilmington, Delaware.  Any party may initiate the arbitration, by
notice in writing to the other party, setting forth the nature of the dispute,
the amount involved, if any, and the remedy sought.  Any party desiring to
initiate arbitration shall serve a written notice of intention to arbitrate to
the other party and to the American Arbitration Association ("AAA") office in
or closest to Wilmington, Delaware, and the AAA will administer such
arbitration in accordance with the Commercial Arbitration Rules of the AAA then
in effect (the "Arbitration Rules").

                 The board of three arbitrators shall be appointed promptly
upon written application of the initiating party, and shall be selected in
accordance with the Arbitration Rules.  All of the arbitrators shall be members
of the National Academy of Arbitrators.  The board of arbitrators appointed
hereunder shall conduct the arbitration pursuant to the Arbitration Rules,
except as such rules may be modified for the purpose of the arbitration
proceeding by mutual written agreement of the parties to this Agreement.  No
depositions may be taken or other discovery obtained except for the exchange of
documents and witness lists as provided by the Arbitration Rules or by the
mutual agreement of the parties.

                 The award of the arbitrators, or a majority of them, shall be
final and binding upon the parties hereto and judgment thereon may be entered
in any court having jurisdiction.  All statutes of limitations which would
otherwise be applicable shall apply to any arbitration proceeding hereunder.
The provisions of this section shall survive any termination, amendment, or
expiration of this Agreement unless all the parties hereto otherwise expressly
agree in writing.

                 The arbitrators, or a majority of them, may award reasonable
attorney's fees and costs to the prevailing party pursuant to the terms of this
Agreement.

                 Except as set forth above concerning awards to the prevailing
party, each party shall bear its own expenses in connection with preparation
for the presentation of its case at the arbitration proceedings and the fees
and expenses of the arbitrators and all other expenses of the arbitration
(except those referred to in the preceding sentence) shall be borne equally by
the parties to such arbitration.

         14.9    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.

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

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

         14.11   INTEGRATION OF EXHIBITS.  All Exhibits attached to this
Agreement are integral parts of this Agreement as if fully set forth herein,

and not only in connection with the specific representation in which they are
explicitly referenced.

         14.12   ENTIRE AGREEMENT .  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.

         14.13   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.

         14.14   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 (other than PRG, which is deemed to
be a third-party beneficiary with respect to this Agreement) 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
party; provided, however, that Purchaser may assign its rights and obligations
hereunder to an affiliate of Purchaser.

         14.15   NO RULE OF CONSTRUCTION.  The parties acknowledge that this
Agreement was initially prepared by Purchaser, 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.

         14.16   COSTS OF ENFORCEMENT. In the event that Purchaser, on the one
hand, or Seller, on the other hand, file suit in any court against the 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.

         14.17   PRORATIONS.  Seller agrees to reimburse Purchaser at Closing a
pro rata portion of all ad valorem Taxes levied upon the Assets for the
calendar year in which the Closing occurs.  Such ad valorem Taxes shall be
estimated, apportioned and pro-rated among Seller and Purchaser as of the
Closing Date, and the prorated amount due Purchaser shall be credited to the
Closing Valuation.  Upon payment by Purchaser of such ad valorem Taxes actually
assessed and paid on the Assets, Purchaser shall calculate the apportionment of
such ad valorem 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.

         14.18   WAIVER OF BULK TRANSFER COMPLIANCE.  Seller and Purchaser
hereby waive any compliance with the Bulk Transfers Acts of any states in which
the Assets are located.  Seller covenants and agrees that all of the creditors
with respect to the Business and the Assets will be paid in full by Seller
prior to the Closing Date, except to extent that any liability to such
creditors is assumed by Purchaser pursuant to this Agreement.  If required by
Purchaser, Seller shall furnish Purchaser with proof of payment of all
creditors with respect to the Business and the Assets.  Notwithstanding the
foregoing, Seller may dispute the validity or amount of any such creditor's
claim without being deemed to be in violation of this Section 14.18, provided
that such dispute is in good faith and does not unreasonably delay the
resolution of the claim.

         14.19   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.

         14.20   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





                                       32
<PAGE>   38
Section 14.3 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.

         14.21   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.

         14.22   EMPLOYEES (POST-CLOSING).  For a period of one (1) year
following the Closing Date, Seller shall not directly or indirectly employ or
solicit for employment any employee of the Business or the Division who accepts
employment with Purchaser or PRG.  With respect to persons listed on Exhibit
5.9, PRG will have the ability to continue to evaluate the possibility of
employing such individuals and Seller will cooperate with such evaluation.

         14.23   EQUIVISION NAME.  Following the Closing Date, Seller shall not
sell or license the right to use the names EquiVision or Equivision to any
other person or entity.

         14.24   PARTIES' OBLIGATIONS.  The obligations hereunder of the
parties hereto shall be binding solely with respect to the party to be bound,
and except as explicitly otherwise provided herein, no officer, director,
employee or shareholder of such party shall be a guarantor or shall otherwise
be bound by, or liable for, the non-performance of the obligations hereunder of
such party.

 Determination of Consideration; Escrow Adjustment; Conversion of Shares in the
                                    Merger

       4.1    Determination of Consideration.

           (i)       The aggregate value of the consideration to be paid by the
Acquiror in connection with the consummation of the Merger shall be
$70,000,000, subject to adjustment as set forth in subsection (iv) below.  The
aggregate Merger Consideration shall be comprised of $35,000,000 in cash,
subject to adjustment as set forth in subsection (iv) below (the "Cash
Consideration") and a number of fully paid and nonassessable shares of Acquiror
Common Stock determined in accordance with this Section 4.1 (such shares of
Acquiror Common Stock being referred to herein as the "Stock Consideration").
The Cash Consideration and Stock Consideration are collectively referred to
herein as the "Merger Consideration".

          (ii)       The number of shares of Acquiror Common Stock comprising
the Stock Consideration shall be the quotient of $35,000,000 and the Acquiror
Share Price, as defined in subsection (iii) below, subject to adjustment as set
forth in subsection (iv) below.

         (iii)       The Acquiror Share Price shall be $23.35.

          (iv)       The Merger Consideration shall be subject to reduction by
the Escrow Adjustment (as defined in Section 4.2), if any, and shall be reduced
by an amount equal to the aggregate of any and all of the Corporation's
contractual severance obligations to Messrs. Whatley, Billing and Robbins (the
"Severance Adjustment").  The Merger Consideration shall be subject to increase
by the amount of any Voting Debt (as hereinafter defined) that is converted
into shares of Corporation Common Stock or repaid between the date hereof and
the Effective Time.

       4.2    Mechanics of Escrow Adjustment.

           (i)       As used in this Agreement, the term "Escrow Adjustment"
shall mean that amount determined by multiplying (x) $400,000 less aggregate
Annual Pro Forma Net Income (hereafter defined) represented by letters of
intent (in substantially the form attached hereto as Exhibit 4.2(i)) to acquire
the assets or all of the outstanding capital stock of, and enter into
management services agreements with, eye care practices or ambulatory surgery
centers that are binding on the Acquisition Targets (hereafter defined) to
which the Corporation is a party on the tenth (10th) day prior to the Closing
Date, that meet the Purchase Price Criteria (hereinafter defined) and which
comply with Acquiror's financial, operational and legal due diligence standards
(which the parties acknowledge includes an audit by an independent





                                      3
<PAGE>   9
Medicare/Medicaid consultant) by (y) 25.00.  As used herein, the term
"Acquisition Target" shall mean one of the eye care practices or ambulatory
surgery centers that is identified on Exhibit 4.2(i)(c), which shall be
provided to Acquiror and Merger Sub by the Corporation by 5:00 p.m., e.d.t.
October 8, 1996.  As used herein, the term "Purchase Price Criteria" shall mean
a purchase price not to exceed fourteen (14) times Annual After Tax
Contribution (hereafter defined), a minimum of fifty percent (50%) of which
shall consist of shares of Acquiror Common Stock, the issuance of which is
unregistered or the resale of which is contractually restricted so that the
shares may be sold only in accordance with the holding period and volume
limitations of Rule 144 under the Securities Act, of 1933, as amended (the
"Securities Act") and thirty percent (30%) which shall  consist of freely
tradeable shares of Acquiror Common Stock.  As used in this Agreement, Annual
After Tax Contribution shall mean with respect to each Acquisition Target, the
pro forma impact of the Acquisition Target on Acquiror's net income as
calculated on Exhibit 4.2(i)(b).  If the amount calculated pursuant to the
first sentence of this clause (i) is a negative number, there shall be no
Escrow Adjustment.

          (ii)       As used in this Agreement, Annual Pro Forma Net Income
shall mean the net income determined on an accrual basis in accordance with
generally accepted accounting principles consistently applied of each
Acquisition Target adjusted to reflect the pro forma effect on the Acquiror's
Net Income of the acquisition of such Acquisition Target as if such acquisition
had been consummated on January 1, 1996 and annualized for the year ended
December 31, 1996 using Acquiror's accounting methods, estimated useful lives
and policies.  The pro forma adjustments to be made in calculating Annual Pro
Forma Net Income shall include, among other items (i) amortization of any
intangible assets created in the acquisition of an Acquisition Target, (ii) a
factor of 8% of the purchase price for an Acquisition Target representing the
cost of capital, and (iii) calculation of income taxes, exclusive of any
nonrecurring tax benefits.  Annual Pro Forma Net Income as of the Closing Date
shall be calculated by Acquiror and approved by the Corporation using
Acquiror's accounting methods, estimated useful lives, and policies and in
accordance with generally accepted accounting principles, consistently applied,
and application of the pro forma adjustments discussed above.  In order to
determine the amount of the Escrow Adjustment, on or prior to the sixth day
prior to the Closing Date, Acquiror shall deliver to Thomas R. Whatley, in
writing, Acquiror's calculation of the Annual Pro Forma Net Income.  If Thomas
R. Whatley objects to Acquiror's calculation of the Annual Pro Forma Net
Income, he shall so inform Acquiror in writing (a "Dispute Notice") within two
days of receipt by Thomas R. Whatley of Acquiror's calculation.  In the absence
of such Dispute Notice, Acquiror's calculation shall be final and binding on
each party to this Agreement.  If a Dispute Notice is delivered to Acquiror,
Acquiror and Thomas R. Whatley shall negotiate in good faith to resolve any
differences related to the calculation of the Annual Pro Forma Net Income
promptly following delivery of the Dispute Notice.  If Acquiror and Thomas R.
Whatley fail to reach agreement after one day of such good faith negotiations,
then the Annual Pro Forma Net Income shall be determined by a partner in the
Houston, Texas office of Coopers & Lybrand, L.L.P. with significant health care
experience (the "Determining Party"), whose determination of the Annual Pro
Forma Net Income shall be final and binding on each party hereto.  In the event
that it is necessary for the Determining Party to calculate the Annual Pro
Forma Net Income, Acquiror and Thomas R. Whatley will fully cooperate with the
Determining Party in order to enable the Determining Party to reach its
determination as soon as practicable, but in





                                      4
<PAGE>   10
no event later than the Closing Date.  The cost of retaining the Determining
Party will be borne fifty percent (50%) by Acquiror and fifty percent (50%)
through a deduction from the Escrow Adjustment.

         (iii)       On the Closing Date the Escrow Adjustment, if any, shall
be placed into escrow with U.S. Trust Company of Texas, N.A. or another
financial institution mutually acceptable to Acquiror and the Corporation
pursuant to an escrow agreement having terms reasonably acceptable to Acquiror
and the Corporation that are consistent with the terms of this Agreement.  The
amounts placed in escrow shall be comprised of fifty percent (50%) cash and
fifty percent (50%) freely tradeable shares of Acquiror Common Stock, based on
a per share value equal to the Acquiror Stock Price.

          (iv)       To the extent that within 30 days following the Closing
Date the Acquiror has been provided by any of Thomas R. Whatley, James C.
Washburn, Kathryn L. Sweers and Eric Ostarly with letters of intent related to
Acquisition Targets or that within 120 days following the Closing Date Acquiror
or any Acquiror Subsidiary has consummated an acquisition involving an
Acquisition Target (a "Subsequent Acquisition") representing Annual Pro Forma
Net Income in an amount up to the Escrow Adjustment, on the later of the 135th
day following the Closing Date or such date upon which the Determining Party
(as defined below) reaches its determination, that portion of the Escrow
Adjustment (together with any interest thereon) obtained by multiplying the
amount of additional Annual Pro Forma Net Income represented by the additional
letters of intent and Subsequent Acquisitions by 25, shall be transferred to
Exchange Agent (hereinafter defined) for the benefit of the shareholders of the
Corporation, fifty percent (50%) in cash and fifty percent (50%) in Acquiror
Common Stock based on the Acquiror Stock Price, and the remainder of the Escrow
Adjustment (together with any interest thereon) shall be released to Acquiror.
If the Annual Pro Forma Net Income represented by the additional letters of
intent and Subsequent Acquisitions is equal to or exceeds the Escrow
Adjustment, the entire Escrow Adjustment (together with any interest thereon)
shall be distributed to the Exchange Agent (hereinafter defined) for the
benefit of the shareholders of the Corporation.  If within 120 days following
the Closing Date, the Acquiror has not been provided any additional letters of
intent to acquire Acquisition Targets or consummated a Subsequent Acquisition,
on the 135th day following the Closing Date the Escrow Adjustment (together
with any interest thereon) shall be released to Acquiror.  On or prior to the
125th day following the Closing Date, Acquiror shall deliver to Thomas R.
Whatley in writing, Acquiror's calculation of the additional Annual Pro Forma
Net Income.  If Thomas R.  Whatley objects to Acquiror's calculation of the
additional Annual Pro Forma Net Income, he shall deliver to Acquiror a Dispute
Notice within five days of receipt by Thomas R. Whatley of Acquiror's
calculation.  In the absence of such Dispute Notice, Acquiror's calculation
shall be final and binding on each party to this Agreement.  If a Dispute
Notice is delivered to Acquiror, Acquiror and Thomas R. Whatley shall negotiate
in good faith to resolve any differences related to the calculation of the
additional Annual Pro Forma Net Income promptly following delivery of the
Dispute Notice.  If Acquiror and Thomas R. Whatley fail to reach agreement
after three business days of such good faith negotiations, then the additional
Annual Pro Forma Net Income shall be determined by the Determining Party, whose
determination of the additional Annual Pro Forma Net Income shall be final and
binding on each party hereto.  In the event that it is necessary for the





                                      5
<PAGE>   11
Determining Party to calculate the additional Annual Pro Forma Net Income,
Acquiror and Thomas R. Whatley will fully cooperate with the Determining Party
in order to enable the Determining Party to reach its determination as soon as
practicable, but in no event later than 15 days after the matter is referred to
the Determining Party.  The cost of retaining the Determining Party will be
borne equally fifty percent (50%) by Acquiror and fifty percent (50%) through a
deduction from the Escrow Adjustment.

       4.3    Conversion of Shares.

           (i)       (a)    At the Effective Time, each share of Corporation
       Common Stock issued and outstanding immediately prior to the Effective
       Time (other than shares of Corporation Common Stock held by persons who
       object to the Merger and comply with all provisions of the Florida law
       concerning the right of such holders to dissent from the Merger and
       demand appraisal of their shares ("Dissenting Common Holders")) 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 Merger Consideration
       Per Share and the Escrow Adjustment Per Share.  As used herein, the term
       "Merger Consideration Per Share" shall mean the amount determined in
       accordance with the following formula:

       M =  C - D 
            -----
              S

       M =    the Merger Consideration Per Share of Corporation Common Stock

       C =    $70,000,000 minus the Escrow Adjustment, minus the Severance
              Adjustment and minus the aggregate amount paid pursuant to
              Section 4.3(v) hereof and plus the amount of any Voting Debt that
              is converted into shares of Corporation Common Stock or repaid
              between the date hereof and the Effective Time.

       D =    the aggregate amount of accrued and unpaid dividends on the
              Convertible Preferred Stock as of the Effective Time.

       S =    the number of shares of Corporation Common Stock outstanding at
              the Effective Time (including as outstanding all shares issuable
              upon the conversion of all outstanding shares of Convertible
              Preferred Stock (as defined in Section 5.3 hereof) and the
              exercise of all outstanding warrants to purchase shares of
              Corporation Common Stock).

                     (b)    At the Effective Time, each share of Convertible
       Preferred Stock (as hereinafter defined) of the Corporation issued and
       outstanding immediately prior to the Effective Time (other than shares
       of Convertible Preferred Stock held by persons who object to the Merger
       and comply with all provisions of the Florida Act concerning the right
       of such holders to dissent from the Merger and demand appraisal of their
       shares (together with the Dissenting Common Holders, the "Dissenting
       Holders")) shall, by





                                      6
<PAGE>   12
       virtue of the Merger and without any action on the part of the holder
       thereof, be converted into the right to receive (A) an amount equal to
       accrued and unpaid dividends on such share as of the Effective Time,
       payable fifty percent (50%) in cash and fifty percent (50%) in shares of
       Acquiror Common Stock based on the Acquiror Stock Price, plus (B) an
       amount equal to the Merger Consideration Per Share multiplied by the
       number of shares of Corporation Common Stock into which such share is
       convertible, in accordance with its terms, as of the Effective Time,
       plus (C) an amount equal to the Escrow Adjustment Per Share multiplied
       by the number of shares of Corporation Common Stock into which such
       share is convertible, in accordance with its terms, as of the Effective
       Time.

The "Escrow Adjustment Per Share" shall mean the amount of the Escrow
Adjustment transferred to the Exchange Agent pursuant to Section 4.2(iv)
allocated on the same proportionate basis as the Merger Consideration Per
Share.  The Merger Consideration Per Share and Escrow Adjustment Per Share
shall be paid fifty percent (50%) in cash and fifty percent (50%) in shares of
Acquiror Common Stock based on the Acquiror Stock Price.

          (ii)       As a result of the Merger and without any action on the
part of the holder thereof, except as otherwise contemplated by Section
4.3(iii), all shares of Corporation Common Stock shall cease to be outstanding
and shall be cancelled and retired and shall cease to exist, and each holder of
a certificate (a "Certificate") representing any shares of Corporation Common
Stock or Convertible Preferred Stock shall thereafter cease to have any rights
with respect to such shares of Corporation Common Stock or Convertible
Preferred Stock, as the case may be, except the right to receive, without
interest, the Merger Consideration and cash for fractional interests of the
Acquiror Common Stock in accordance with Sections 4.1(i) and 4.4(v)) upon the
surrender of such Certificate.

         (iii)       Each share of Corporation Common Stock issued and
outstanding at the Effective Time and owned by any of the Acquiror, Acquiror
Subsidiaries, and each share of Corporation Common Stock issued and held in the
Corporation's treasury at the Effective Time, by virtue of the Merger and
without any action on the part of the holder thereof, shall cease to be
outstanding and shall be cancelled and retired without payment of any
consideration therefor and shall cease to exist.

          (iv)       At the Effective Time, each share of Common Stock, par
value $0.01 per share, of Merger Sub issued and outstanding immediately prior
to the Effective Time as a result of the Merger shall continue to be an issued
and outstanding share of Common Stock of the Surviving Corporation.  Each
certificate representing immediately prior to the Effective Date issued shares
of Common Stock of Merger Sub shall continue to evidence ownership of the same
number of shares of Common Stock of the Surviving Corporation.

           (v)       Prior to the Effective Time, the Corporation shall offer a
supplemental agreement or agreements to each of the holders of outstanding
options to purchase Corporation Common Stock providing that at the Effective
Time, unless such options have been previously





                                      7
<PAGE>   13
exercised, each such option shall then be automatically redeemed in
consideration for payment mutually agreed upon by such holder and the
Corporation.

          (vi)       At or prior to the Effective Time, any outstanding
redeemable preferred stock of a Corporation Subsidiary (as defined in Section
5.4) shall have been redeemed by such Corporation Subsidiary.

         (vii)       At or prior to the Effective Time, each outstanding
warrant to acquire Corporation Common Stock shall have been exercised by the
holder of such warrant pursuant to the terms thereof.

        (viii)       Notwithstanding anything in this Agreement to the
contrary, shares of Corporation Common Stock outstanding immediately prior to
the Effective Time held by a Dissenting Holder (if any) ("Dissenting Shares")
shall not be converted into a right to receive the Merger Consideration and
cash in lieu of fractional shares in accordance with Sections 4.1(i) and
4.4(v), unless such Dissenting Holder fails to perfect or otherwise loses such
holder's right to appraisal, if any.  If, after the Effective Time, such
Dissenting Holder fails to perfect or loses any such right to appraisal, such
shares shall be treated as if they had been converted as of the Effective Time
into the right to receive the Merger Consideration and cash in lieu of
fractional shares in accordance with Section 4.4(v) hereof.  The Corporation
shall give prompt notice to Acquiror of any demands received by the Corporation
for appraisal of shares of Corporation Common Stock, and Acquiror shall have
the right to participate in and direct all negotiations and proceedings with
respect to such demands.  The Corporation shall not, except with the prior
written consent of Acquiror, make any payment with respect to, or settle or
offer to settle, any such demands.

       4.4    Exchange of Certificates Representing Shares.

           (i)       As of the Effective Time, Acquiror shall make available,
or shall cause to be made available, with an exchange agent selected by
Acquiror, which shall be Acquiror's transfer agent or such other party
reasonably satisfactory to the Corporation (the "Exchange Agent"), for the
benefit of the holders of shares of Corporation Common Stock, for exchange in
accordance with this Article 4, the aggregate Cash Consideration and
certificates representing the aggregate Stock Consideration in each case, less
the Escrow Adjustment, if any (such aggregate Stock Consideration, together
with the amount of any dividends or distributions with respect thereto, the
aggregate Cash Consideration as so deposited, and any of the Escrow Adjustment
so deposited thereafter being hereinafter referred to as the "Exchange Fund")
in exchange for outstanding shares of Corporation Common Stock.

          (ii)       Within a reasonable period following the Effective Time,
Acquiror shall cause the Exchange Agent to mail to each person who was, at the
Effective Time, a holder of record (other than any of the Acquiror, Acquiror
Subsidiaries or the Corporation) of a Certificate or Certificates (a) a letter
of transmittal which shall specify that delivery shall be effected, and the
risk of loss and title to the Certificates shall pass, upon (and only upon)
delivery of the Certificates to the Exchange Agent, and which shall be in such
form and have





                                      8
<PAGE>   14
such other provisions as the Acquiror may reasonably specify, and (b)
instructions for use in effecting the surrender of the Certificates in exchange
for certificates representing Acquiror Common Stock.  Upon surrender to the
Exchange Agent of a Certificate for cancellation together with such letter of
transmittal, duly executed and completed in accordance with the instructions
thereto, the holder of such Certificate shall be entitled to receive in
exchange therefor a certificate representing that number of shares of Acquiror
Common Stock and unpaid dividends and distributions, if any, which such holder
has the right to receive in respect of the Certificate surrendered pursuant to
the provisions of this Article 4 and a check representing the Cash
Consideration which such holder has the right to receive pursuant to the
provisions of this Article 4 (including any cash payable in lieu of any
fractional share of Acquiror Common Stock in accordance with Section 4.4(v)
hereof), after giving effect to any required tax withholdings, and the
Certificate so surrendered shall forthwith be cancelled.  No interest will be
paid or accrued on the amount payable upon surrender of Certificates.  In the
event of a transfer of ownership of shares of Corporation Common Stock which is
not registered in the transfer records of the Corporation, a check and/or one
or more certificates representing the proper amount of Cash Consideration and
Stock Consideration, respectively, may be issued to such a transferee if the
Certificate representing such shares of Corporation Common Stock is presented
to the Exchange Agent, accompanied by all documents required by the Exchange
Agent to evidence and effect such transfer of shares of Corporation Common
Stock and to evidence that any applicable stock transfer taxes have been paid.

         (iii)       Notwithstanding any other provisions of this Agreement, no
dividends on Acquiror Common Stock shall be paid with respect to any shares of
Corporation Common Stock or Convertible Preferred Stock represented by a
Certificate until such Certificate is surrendered for exchange as provided
herein.  Subject to the effect of applicable laws, following surrender of any
such Certificate, there shall be paid to the holder of certificates
representing shares of Acquiror Common Stock issued in exchange therefor,
without interest, (a) at the time of such surrender, the amount of dividends or
other distributions with a record date after the Effective Time theretofore
payable with respect to such shares of Acquiror Common Stock and not paid, less
the amount of any withholding taxes which may be required thereon, and (b) at
the appropriate payment date, the amount of dividends or other distributions
with a record date after the Effective Time but prior to surrender thereof and
a payment date subsequent to surrender thereof payable with respect to such
shares of Acquiror Common Stock, less the amount of any withholding taxes which
may be required thereon.

          (iv)       At or after the Effective Time, there shall be no
transfers on the stock transfer books of the Corporation of shares of
Corporation Common Stock or Convertible Preferred Stock which were outstanding
immediately prior to the Effective Time.  If, after the Effective Time,
Certificates are presented to the Surviving Corporation, they shall be
cancelled and exchanged for certificates for shares of Stock Consideration and
the Cash Consideration in accordance with the procedures set forth in this
Article 4.

           (v)       Notwithstanding any other provision of this Article 4, no
fractional shares of Acquiror Common Stock will be issued and any holder of
shares of Corporation Common Stock or Convertible Preferred Stock entitled
hereunder to receive a fractional share of Acquiror





                                      9
<PAGE>   15
Common Stock but for this Section 4.4(v) will be entitled hereunder to receive
no such fractional share of Acquiror Common Stock but a cash payment in lieu
thereof, which payment shall represent such holder's proportionate interest in
the net proceeds from the sale by the Exchange Agent on behalf of all such
holders of the aggregate fractional shares of Acquiror Common Stock that such
holders would be entitled to receive but for this Section 4.4(v).  Any such
sale shall be made by the Exchange Agent within ten business days after the
date upon which the Certificate(s) that would otherwise result in the issuance
of shares of Acquiror Common Stock have been received by the Exchange Agent.

          (vi)       Any portion of the Exchange Fund (including the proceeds
of any investments thereof and any shares of Acquiror Common Stock) that is
unclaimed by the former shareholders of the Corporation on the first
anniversary of the Effective Time shall be delivered to the Surviving
Corporation.  Any former stockholders of the Corporation who have not
theretofore complied with this Article 4 shall thereafter look to the Surviving
Corporation only as general creditors for payment of their claim for Merger
Consideration, any cash in lieu of fractional shares, and any unpaid dividends
and distributions on shares of Acquiror Common Stock, deliverable in respect of
each share of Corporation Common Stock such stockholder holds as determined
pursuant to this Agreement, in each case without any interest thereon.

         (vii)       None of the Corporation, the Surviving Corporation, Merger
Sub, the Exchange Agent or any other person shall be liable to any former
holder of shares of Corporation Common Stock or Convertible Preferred Stock for
any amount properly delivered to a public official pursuant to applicable
abandoned property, escheat or similar laws.

        (viii)       In the event any Certificate shall have been lost, stolen
or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such person of a bond in such
reasonable amount as the Surviving Corporation may direct as indemnity against
any claim that may be made against it with respect to such Certificate, the
Exchange Agent will issue in exchange for such lost, stolen or destroyed
Certificate the Merger Consideration and cash in lieu of fractional shares, and
unpaid dividends and distributions on shares of Acquiror Common Stock,
deliverable in respect thereof pursuant to this Agreement.

of the properties owned or leased by it therein or in which the transaction of
its business makes such qualification necessary, except where the failure to be
so qualified would not have a material adverse effect on the business of the

copies of its articles of incorporation and bylaws, the articles of
incorporation and bylaws of each Corporation Subsidiary and the partnership
agreement for each Partnership, in each case as amended to the date hereof.

       5.2    Authorization, Validity and Effect of Agreements.  Subject only
to the approval of this Agreement and the Merger by the holders of a majority
of the outstanding shares of Corporation Common Stock, the Corporation has the
requisite corporate power and authority to execute and deliver this Agreement
and all agreements and documents contemplated hereby, and the consummation by
the Corporation of the transactions contemplated hereby, have been duly
authorized by all requisite corporate action.  This Agreement constitutes, and
all agreements and documents contemplated hereby (when executed and delivered
pursuant hereto for value received) will constitute, the valid and legally
binding obligations of the Corporation enforceable in accordance with their
terms, except as the same may be limited by bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting generally the
enforcement of creditors' rights and by general principles of equity.

       5.3    Capitalization.  The authorized capital stock of the Corporation
consists of 10,000,000 shares of Corporation Common Stock and 2,000,000 shares

contract or other funding arrangement has been administered and maintained in

regulations, and all reports required by any governmental agency have been
timely filed.  No Employee Benefit Plan or Compensation Plan is currently the
subject of an audit, investigation, enforcement action or other similar
proceeding conducted by any state or federal agency.  There is no proceeding,
claim (other than routine claims for benefits), lawsuit, or investigation
pending or, to the knowledge of the executive officers of the Corporation,
threatened, concerning or involving any Compensation Plan or Employee Benefit
Plan.  There is no litigation involving, and there are no proceedings before,
the U.S. Department of Labor or any other commission or administrative or
regulatory authority pending against the Corporation, any of the Corporation
Subsidiaries, or any ERISA Affiliate, or against any fiduciary of any
Compensation Plan or Employee Benefit Plan, relating to claims for benefits,
breaches of duties or relating in any way to the maintenance or operation of
such plans, and, to the knowledge of the executive officers of the Corporation,
no such claim exists or has been threatened.

           (v)       No prohibited transactions (within the meaning of Section
4975 of the Code and Section 406 of ERISA) have occurred with respect to any
Employee Benefit Plan nor has there been any transaction which could subject
any Corporation ERISA Entity to any material liability under Section 4972 and

respect to the Compensation Plans or the Employee Benefit Plans.

          (vi)       A Corporation ERISA Entity has received a current
favorable determination letter or ruling from the Internal Revenue Service for
each Employee Benefit Plan, and each amendment thereto, intended to be
qualified within the meaning of Section 401(a) of the Code and/or tax-exempt

meaning of Section 501(c)(9) of the Code, all necessary governmental approvals
for obtaining tax exempt status have been obtained, and such determination
letter is dated on or after January 1, 1985.

         (vii)       As of the last day of the most recent plan year ended

Corporation ERISA Entity under the terms of any Employee Benefit Plan have been
timely made or have been reflected on its balance sheet and (A) no accumulated
funding deficiency within the meaning of Section 412 of the Code or 302(f) of
ERISA, whether waived or unwaived, exists with respect to any Employee Benefit
Plan or any plan sponsored or maintained by any Corporation ERISA Entity, (B)

401(a)(29) of the Code, (C) no





                                      19
<PAGE>   25
lien exists or will arise within 60 days after the Closing Date pursuant to
Section 412(n) of the Code or Section 302(f) of ERISA due to any failure to
make any contributions required thereby and (D) the fair market value of the
assets of each funded defined benefit pension plan equals or exceeds the
actuarial present value of the vested and nonvested accrued benefits under such
pension plan as calculated upon a standard termination of a defined benefit
plan subject to Title IV of ERISA with such actuarial present value determined
by application of the actuarial methods and assumptions set forth in such
defined benefit pension plan or the methods and assumptions prescribed by the
Pension Benefit Guaranty Corporation ("PBGC") for the valuation of such
benefits in connection with such plans being terminated thereunder.
Administrative expenses, trustee fees, similar charges and taxes if any, shall
be taken into account for purposes of the foregoing computations.  The assets
of each voluntary employees beneficiary association maintained by each
Corporation ERISA Entity equal or exceed the present value of benefit
obligations incurred under each such plan (determined in accordance with
actuarial standards applied in the ongoing administration of such plans) as of
the last day of the most recent plan year ended prior to the date hereof.

        (viii)       No Corporation ERISA Entity is obligated to contribute to
a multi-employer plan within the meaning of Sections 3(37) and 4001(a)(3) of
ERISA and no Corporation ERISA Entity has incurred any "withdrawal liability"
(as defined in Section 4201 et seq. of ERISA) which has not been satisfied as
of the Closing.

          (ix)       No facts or circumstances exist that would result in the
imposition of liability against any Corporation ERISA Entity by the PBGC as a
result of any act or omission by any Corporation ERISA Entity.  No reportable
event (within the meaning of Section 4043 of ERISA) for which the notice
requirement has not been waived has occurred with respect to any Employee
Benefit Plan subject to the requirements of Title IV of ERISA.  No liability to
the PBGC has been incurred by any Corporation ERISA Entity on account of any

been required to be disclosed in the Corporation Disclosure Letter had such
contract or agreement been entered into prior to the date of this Agreement, is

of time or both, would be a material default) by the Corporation, any
Corporation Subsidiary, or any Partnership, or, to the knowledge of the
executive officers of the Corporation, any other party, in the timely
performance of any obligation to be performed or paid under any of Contracts or

       the Corporation which is still in effect, the Corporation is not in

              (c)    as of the date of this Agreement, to the knowledge of the
       executive officers of the Corporation, there are no pending or
       threatened condemnation or eminent domain proceedings with respect to

Partnerships, the Corporation ASC's and, to the knowledge of the executive
officers of the Corporation, the Affiliated Practices are in compliance with

including the name of each insurer, the amount of coverage provided under the
policy, all persons, groups and entities that are afforded coverage under the

any Partnership, any Corporation ASC or any Affiliated Practice is in default
under any insurance policy or bond described in Section 5.28, and no event
which would (with the passage of time, notice or both) constitute a breach or
default thereunder by the Corporation, any Corporation Subsidiary, any
Partnership, any Corporation ASC or any Affiliated Practice or, to the
knowledge of the executive officers of the Corporation, the insurer thereunder,
has occurred, or, to the knowledge of the executive officers of the
Corporation, will occur as a result of the transactions contemplated herein.
Consummation of the transactions contemplated herein will not (and will not
give any person or entity a right to) terminate or modify any material rights
of, or accelerate or augment any material obligation of the Corporation, any
Corporation Subsidiary, any Partnership, any Corporation ASC or any Affiliated
Practice under any insurance policy or bond insofar as such policy or bond
relates to or covers incidents that give rise to claims for incidents taking
place prior to the Closing Date.  Neither the Corporation, any Corporation
Subsidiary, any Partnership, any Corporation ASC nor any Affiliated Practice
have done anything by way of action or inaction which might invalidate or
diminish coverage under any of such policies in whole or in part.  There are no
outstanding requirements or recommendations of any insurance company that has
issued a policy to the Corporation, any Corporation Subsidiary, any
Partnership, any Corporation ASC or any Affiliated Practice which require or
recommend any material changes to the conduct of the business of the

<PAGE>   33
material mortgages, liens, charges, encumbrances, or title defects of any
nature whatsoever, except for such mortgages, liens, charges, encumbrances or
title defects which would not materially and adversely affect the value of such
property as carried on the Corporation's consolidated financial statements
contained in the Preliminary Prospectus or would not have a material adverse
effect on the Corporation, any Corporation Subsidiary or any Partnership.  The
Corporation, the Corporation Subsidiaries and the Partnerships have valid and
enforceable leases for the premises and the equipment, furniture and fixtures
purported to be leased by them, except for leases, the failure of which to have
or be enforceable, would not have a Corporation Adverse Effect.

         5.30    No Material Adverse Effect.  Except as disclosed in the
Corporation's financial reports set forth in the Preliminary Prospectus or in
the Corporation Disclosure Letter, the Corporation is not aware of any fact
which, alone or together with another fact, has resulted in or is likely to
result in a Corporation Adverse Effect.

existing options, warrants, calls, subscriptions, convertible securities, or
other rights or other agreements or commitments which obligate Acquiror or any
of the Acquiror Subsidiaries (hereinafter defined) to issue, transfer or sell
any shares of capital stock of Acquiror or any of the Acquiror Subsidiaries
(hereinafter defined).

         6.4     Subsidiaries.  Except as set forth in the Acquiror Disclosure
Letter, Acquiror owns directly or indirectly each of the outstanding shares of
capital stock of each of Acquiror's subsidiaries (individually, a "Acquiror
Subsidiary" and collectively, the "Acquiror Subsidiaries").  Each Acquiror
Subsidiary is duly licensed or qualified to do business as a foreign
corporation and is in good standing under the laws of each jurisdiction in
which the character of the properties owned or leased by it therein or in which
the transaction of its business makes such qualification necessary, except
where the failure to be so qualified would not have an Acquiror Adverse Effect.

         6.5     Noncontravention.  Except as set forth in the Acquiror
Disclosure Letter, neither the execution and delivery by Acquiror of this
Agreement, nor the consummation by Acquiror





                                      29
<PAGE>   35
of the transactions contemplated hereby in accordance with the terms hereof,
will:  (i) conflict with or result in a breach of any provisions of the
certificate of incorporation or bylaws of Acquiror; (ii) violate, or conflict
with, or result in a material breach of any provision of, or constitute a
default (or an event which, with notice or lapse of time or both, would
constitute a default) under, or result in the termination or in a right of
termination or cancellation of, or accelerate the performance required by, or
result in the creation of any material lien, security interest, charge or
encumbrance upon any of the material properties of Acquiror under, or result in
being declared void, voidable, or without further binding effect, any of the
terms, conditions or provisions of any Contract to which Acquiror is a party,
or by which Acquiror or any of its properties is bound or affected except with
respect to matters which are not material to the business of Acquiror taken as
a whole; or (iii) other than the filings specified in Article 1 hereof and the
Regulatory Filings, require any material consent, approval or authorization of,
or declaration, filing or registration with, any domestic governmental or
regulatory authority, of which the failure to obtain would have an Acquiror
Adverse Effect.

         6.6     Financial Statements.  Acquiror has delivered to the
Corporation Acquiror's Annual Report on Form 10-K for the year ended December
31, 1995, together with all amendments thereto, Acquiror's Quarterly Report on
Form 10-Q for the quarter ended March 31 and June 30, 1996, and Acquiror's
definitive proxy statement for the 1996 annual meeting of stockholders of
Acquiror held on May 21, 1996, and each of the Acquiror's Current Reports on
Form 8-K, each in the form (including exhibits and any amendments or
supplements thereto) filed with the Securities and Exchange Commission ("SEC")
(collectively, the "Acquiror Reports").  As of their respective dates, the
Acquiror Reports (i) were prepared in accordance with the requirements of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules
and regulations thereunder and (ii) did not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements made therein, in the light of the
circumstances under which they were made, not misleading.  Each of the
consolidated balance sheets of Acquiror included in the Acquiror Reports
(including any related notes and schedules) fairly presents the consolidated
financial position of Acquiror and the Acquiror Subsidiaries as of its date and
each of the consolidated statements of income, retained earnings and cash flows
of Acquiror included in the Acquiror Reports (including any related notes and
schedules) fairly presents the consolidated results of operations, retained
earnings and cash flows, as the case may be, of Acquiror and the Acquiror
Subsidiaries for the periods set forth therein (subject, in the case of
unaudited statements, to normal year-end adjustments which would not be
material in amount or effect), in each case in accordance with generally
accepted accounting principles consistently applied during the periods
involved, except as may be noted therein.  Except as and to the extent set
forth on the unaudited consolidated balance sheet of Acquiror and the Acquiror
Subsidiaries at June 30, 1996, including all notes thereto, neither Acquiror
nor any of the Acquiror Subsidiaries has any material liabilities or
obligations of any nature (whether accrued, absolute, contingent or otherwise)
that would be required to be reflected on, or reserved against in, a
consolidated balance sheet of Acquiror or in the notes thereto, prepared in
accordance with generally accepted accounting principles consistently applied,
except liabilities arising in the ordinary course of business since such date.

Acquiror, threatened against Acquiror or any Acquiror Subsidiary, at law or in
equity, or before or by any federal, state or local commission, board, bureau,
agency or instrumentality that are reasonably likely to have an Acquiror
Adverse Effect.

         6.8     Absence of Certain Changes.  Except as disclosed in the
Acquiror Disclosure Letter or Acquiror Reports filed with the SEC prior to the
date hereof and except for changes arising from the public announcement of the

conducted its business only in the ordinary course of such business and there
has not been (i) any material adverse change in such business; (ii) any
declaration, setting aside or payment of any dividend or other distribution

federal, state, local and foreign tax returns required to be filed by it for

expired and all such filed returns are complete in all material respects, (ii)

(iii) has properly accrued all such taxes for periods subsequent to the periods

         6.10    Labor Matters.  Acquiror is not a party to or bound by any
collective bargaining agreement.  There is no unfair labor practice or labor
arbitration proceeding pending or, to the actual knowledge of the executive
officers of Acquiror, threatened relating to its business.  To the actual
knowledge of the executive officers of Acquiror, there are not any
organizational efforts presently being made or threatened involving employees
of Acquiror.

         6.11    No Brokers.  Acquiror has not entered into any contract,
arrangement or understanding with any person or firm which may result in the
obligation of Acquiror to pay any finder's fees, brokerage or agent's
commissions or other like payments in connection with the negotiations leading
to this Agreement or the consummation of the transactions contemplated hereby,
except that Acquiror has retained Smith Barney Inc. as its financial advisor,
the arrangements with which have been set forth in the Acquiror Disclosure
Letter.

         6.12    Capital Stock.  The shares of Common Stock of Merger Sub are
validly issued, fully paid and nonassessable and are owned directly by
Acquiror, free and clear of all liens, claims and encumbrances.  The issuance
and delivery by Acquiror of shares of Acquiror Common Stock in connection with
the Merger have been duly and validly authorized by all necessary corporate
action on the part of Acquiror.  The shares of Acquiror Common Stock to be
issued in connection with the Merger, when issued in accordance with the terms
of this Agreement, will be validly issued, fully paid and nonassessable and
listed on the NYSE.

         6.13    Opinion of Acquiror's Financial Advisor.  The Board of
Directors of Acquiror has received the opinion of Smith Barney Inc., financial
advisor to Acquiror, to the effect that,





                                      31
<PAGE>   37
as of the date of this Agreement, the Merger Consideration is fair to Acquiror
from a financial point of view.

         6.14    Compliance with Applicable Laws.  Acquiror and the Acquiror
Subsidiaries hold all permits, licenses, variances, exemptions, orders and
approvals of all Governmental Entities, except for such permits, licenses,
variances, exemptions, orders and approvals the failure of which to hold would
not have an Acquiror Adverse Effect (the "Acquiror Permits").  Acquiror and the
Acquiror Subsidiaries are in compliance with the terms of the Acquiror Permits,
except for such failures to comply, which singly or in the aggregate, would not
have an Acquiror Adverse Effect.  Except as disclosed in the Acquiror Reports
filed prior to the date of this Merger Agreement, the businesses of Acquiror
and the Acquiror Subsidiaries are not being conducted in violation of any law,
ordinance or regulation of any Governmental Entity, except for possible
violations which individually or in the aggregate do not and would not have an
Acquiror Adverse Effect.  No investigation or review by any Governmental Entity
with respect to Acquiror or any of the Acquiror Subsidiaries is pending, or, to
the knowledge of the executive officers of Acquiror, threatened, nor has any
Governmental Entity indicated an intention to conduct the same, other than
those the outcome of which would not have an Acquiror Adverse Effect.

         6.15    Certain Agreements.  Except as disclosed in the Acquiror
Reports filed prior to the date of this Agreement or as set forth in the
Acquiror Disclosure Letter, neither Acquiror nor any of the Acquiror
Subsidiaries is a party to any oral or written (i) agreement, contract,
indenture or other instrument relating to Indebtedness in an amount exceeding
$1,000,000 or (ii) other contract, agreement or commitment (except those
entered into in the ordinary course of business).  Neither Acquiror nor any of
the Acquiror Subsidiaries is in default (with or without notice or lapse of
time, or both) under any indenture, note, credit agreement, loan document,
lease, license or other agreement including, but not limited to, any benefit
plan, whether or not such default has been waived, which default, alone or in
the aggregate with other such defaults, would have an Acquiror Adverse Effect.

         6.16    Accounts Receivable.  The accounts receivable of Acquiror and
the Acquiror Subsidiaries as reflected in the most recent financial statements
contained in the Acquiror Reports, to the extent uncollected on the date
hereof, and the accounts receivable reflected on the books of Acquiror and the
Acquiror Subsidiaries are valid and existing and represent monies due, and
Acquiror has made reserves reasonably considered adequate for receivables not
collectible in the ordinary course of business, and (subject to the aforesaid
reserves) are subject to no refunds or other adjustments and to no defenses,
rights of setoff, assignments, restrictions, encumbrances or conditions
enforceable by third parties on or affecting any thereof, except for such
refunds, adjustments, defenses, rights of setoff, assignments, restrictions,
encumbrances or conditions as would not have an Acquiror Adverse Effect.

         6.17    No Material Adverse Effect.  Except as disclosed in the

contained in this Agreement and no statement contained in any certificate,
list, exhibit or other instrument specified in this Agreement, including
without limitation the Acquiror Disclosure Letter, contains any untrue
statement of a material fact or omits or will omit to state a material fact
necessary to make the statements contained herein or therein, in light of the
circumstances under which they were made, not misleading.

         6.19    Inventory.  The inventories of Acquiror and the Acquiror
Subsidiaries as reflected in the most recent financial statements contained in
the Acquiror Reports, or acquired by Acquiror or any of the Acquiror
Subsidiaries after the date thereof, (i) are carried as provided in the
Acquiror Reports not in excess of the lower of cost or net realizable value and
(ii) do not include any inventory which is obsolete, surplus or not usable or
saleable in the lawful and ordinary course of business of Acquiror and the
Acquiror Subsidiaries as heretofore conducted, in each case net of reserves
provided therefor.

Subsidiaries have all patents, trademarks, trade names, service marks, trade
secrets, copyrights and licenses and other proprietary intellectual property
rights and licenses as are necessary in connection with the businesses of
Acquiror and the Acquiror Subsidiaries, the lack of which would have an
Acquiror Adverse Effect, and Acquiror does not have any knowledge of any
conflict with the rights of Acquiror and the Acquiror Subsidiaries therein or
any knowledge of any conflict by them with the rights of others therein which,
insofar as reasonably can be foreseen, could have an Acquiror Adverse Effect.

         6.21    Product Liability.  Except as disclosed in the Acquiror
Disclosure Letter, Acquiror is not aware of any claim, or the basis of any
claim, against Acquiror or any of the Acquiror Subsidiaries for injury to
person or property of employees or any third parties suffered as a result of
the sale of any product or performance of any service by Acquiror or any of the
Acquiror Subsidiaries, including claims arising out of the defective or unsafe
nature of its products or services, which could have an Acquiror Adverse

will have, full and adequate insurance coverage for potential product liability
claims against it.

         6.22    Environment.  Except as disclosed in the Acquiror Disclosure
Letter, there are, with respect to Acquiror or any of the Acquiror
Subsidiaries, no past or present violations of Environmental Laws, releases of
any material into the environment, actions, activities, circumstances,
conditions, events, incidents, or contractual obligations which may give rise
to any common law liability or any liability under CERCLA or similar state or
local laws, which liabilities, either individually or in the aggregate, would
have an Acquiror Adverse Effect.

         6.23    Title to Assets; Liens.  Except as disclosed in the Acquiror
Disclosure Letter, to the extent material to the business or operations of
Acquiror and the Acquiror Subsidiaries, Acquiror has good and marketable title

accounts receivable), property, equipment and other assets, and such assets are
free and clear of any material mortgages, liens, charges, encumbrances, or
title defects of





                                      33
<PAGE>   39
any nature whatsoever, except for such mortgages, liens, charges, encumbrances
or title defects which would not materially and adversely affect the value of
such property as carried on Acquiror's financial statements contained in the
Acquiror Reports or would not have an Acquiror Adverse Effect.  Acquiror and
the Acquiror Subsidiaries have valid and enforceable leases for the premises
and the equipment, furniture and fixtures purported to be leased by them,
except for leases, the failure of which to have or be enforceable, would not
have an Acquiror Adverse Effect.

statement on Form S-4 (registration no. 333- 09905), in the form in which it
became effective, and the prospectus forming a part thereof comply in all
material respects with the provisions of the Securities Act and do not contain
an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading.  The transaction pursuant to which the Stock Consideration will be
issued has been registered pursuant to such registration statement and the
Stock Consideration, upon its issuance pursuant to the terms hereof, shall be
freely tradeable, subject to the provisions of Rule 145 under the Securities
Act.

cooperate and promptly prepare as soon as practicable a proxy statement with
respect to the meetings of the stockholders of the Corporation to approve the

to the extent that any such untrue statement of a material fact or omission to
state a material fact was made by Acquiror in reliance upon and in conformity
with written information concerning the Corporation furnished to Acquiror by
the Corporation specifically for use in the Information Statement.  The
Corporation agrees that the information provided by it for inclusion in the
Information Statement, when the Information Statement is mailed to
Corporation's stockholders, will not include an untrue statement of a material
fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.  No amendment or supplement to the
Information Statement will be made by Acquiror until it has consulted with the
Corporation and its counsel.

             (ii)         Acquiror intends to file with the SEC a Current

executive officer of the Corporation relating to, a default or event that, with
notice or lapse of time or both, would become a default, received by the
Corporation, any of the Corporation Subsidiaries, or any Partnership,
subsequent to the date of this Agreement and prior to the Effective Time, under
any Contract material to the businesses of the Corporation, the Corporation
Subsidiaries and the Partnerships taken as a whole and to which the
Corporation, one of the Corporation Subsidiaries or a Partnership is a party or
is subject; and (b) any change that results in a Corporation Adverse Effect.
The Corporation shall give prompt notice to Acquiror when any notice or other
communication from any third party becomes known to an executive officer of the
Corporation alleging that the consent of such third party is or may be required
in connection with the transactions contemplated by this Agreement.

             (ii)         The Corporation shall give prompt notice to Acquiror,
and Acquiror or Merger Sub shall give prompt notice to the Corporation, of (a)
any representation or warranty made by it contained in this Agreement that is
qualified as to materiality becoming untrue or inaccurate in any respect or any
such representation or warranty that is not so qualified becoming untrue or
inaccurate in any material respect and (b) the failure by it to comply with





                                      39
<PAGE>   45
or satisfy in any material respect any covenant, condition or agreement to be

no such notification shall affect the representations, warranties, covenants or
agreements of the parties or the conditions to the obligations of the parties
under this Agreement.

         7.14    Legal Conditions to Merger.  Each party shall use its best
efforts to take, or cause to be taken, all actions necessary to comply promptly

conditions set forth in this Agreement, to consummate the transactions
contemplated by this Agreement.  Each party will promptly cooperate with and

suffered by, or requirement imposed upon, it or any of its subsidiaries or
affiliated partnerships in connection with the foregoing.

         7.15    Agreements by Affiliated Stockholders of the Corporation and

         At least ten days prior to the shareholders' meeting date for the
Corporation or the date upon which the shareholders take action by written
consent, the Corporation shall deliver to Acquiror a list of names and address
of those persons who were, in the Corporation's reasonable judgment, at the
record date for the stockholders' meeting, "affiliates" of the Corporation
within the meaning of Rule 145 (each such person, together with the persons
identified below, an "Affiliate") of the rules and regulations promulgated
under the Securities Act ("Rule 145").  The Corporation shall provide Acquiror
such information and documents as Acquiror shall reasonably request for
purposes of reviewing such list.  There shall be added to such list the names
and addresses of any other person (within the meaning of Rule 145) which
Acquiror reasonably identifies (by written notice to the Corporation within
five business days after Acquiror's receipt of such list) as being a person who
may be deemed to be an Affiliate of the Corporation within the meaning of Rule
145; provided that no such person identified by Acquiror shall be added to the
list of Affiliates of the Corporation if Acquiror shall receive from the
Corporation, on or before the Effective Time, an opinion of counsel reasonably
satisfactory to Acquiror to the effect that such person is not an Affiliate.
The Corporation shall use all reasonable efforts to deliver or cause to be
delivered to Acquiror, prior to the Effective Time, from each Affiliate who
will, upon consummation of the Merger, beneficially own in excess of 1% of the
outstanding shares of Acquiror Common Stock, Affiliates Letters in the form
attached hereto as Exhibit 7.15.  Acquiror and Merger Sub shall be entitled to
place legends as specified in such Affiliates Letters on the Certificate(s)
evidencing any Acquiror Common Stock to be received by such Affiliates pursuant
to the terms of this Agreement, and to issue appropriate stop transfer
instructions to the transfer agent for Acquiror Common Stock, consistent with
the terms of such Affiliate Letters.

         7.16    Service Agreements.  Following the review of the management
services agreements to which Corporation and the Corporation Subsidiaries are
parties, Acquiror may require certain modifications to conform those management
services agreements and other agreements with the Affiliated Practices to
similar agreements to which Acquiror or the Acquiror Subsidiaries are parties.
The Corporation shall use its best efforts to effect such modifications.

Acquiror and Merger Sub may rely on the failure of any condition set forth in
Section 8.1, 8.2 or 8.3, as the case may be, to be satisfied if such failure

efforts to consummate the Merger and the other transactions contemplated by

                                   ARTICLE 9

                                  Termination

         9.1     Termination by Mutual Consent.  This Agreement may be
terminated and may be abandoned at any time prior to the Effective Time, before
or after the approval of this Agreement by the shareholders of the Corporation,
by the mutual consent of Acquiror, Merger Sub and the Corporation.

         9.2     Termination by Either Acquiror or the Corporation.  This
Agreement may be terminated and the Merger may be abandoned by action of the
Board of Directors of either Acquiror or the Corporation if: (i) the Merger
shall not have been consummated by January 31, 1997; or (ii) the approval of
the Corporation's shareholders required by Section 8.1(i) shall not have been
obtained at a meeting duly convened therefor or at any adjournment thereof or
pursuant to written consent by the shareholders, by January 31, 1997; provided,
in the case of a termination pursuant to clause (i) above, the terminating

         9.3     Termination by the Corporation.  This Agreement may be
terminated and the Merger may be abandoned at any time prior to the Effective
Time, before or after the adoption and approval by stockholders of the

recommendation of this Agreement or the Merger, (ii) there has been a breach by
Acquiror or Merger Sub of any representation, warranty, covenant or agreement
contained in this Agreement which would have an Acquiror Adverse Effect which
is not curable or, if curable, is not cured within 30 days after written notice
of such breach is given by the Corporation to the party committing such breach,
or (iii) within three business days after receipt of the Acquiror Disclosure
Letter if, in the judgment of the Board of Directors of the Corporation, the
matters described in the Acquiror Disclosure Letter could, individually or in

Effect.

         9.4     Termination by Acquiror.

              (i)         This Agreement may be terminated and the Merger may
be abandoned at any time prior to the Effective Time by action of the Board of
Directors of Acquiror, if (a) the Board of Directors of the Corporation shall
have recommended to shareholders of the Corporation an Acquisition Proposal, or
(b) there has been a breach by the Corporation of any representation, warranty,
covenant or agreement contained in this Agreement which would have a
Corporation Adverse Effect which is not curable or, if curable, is not cured
within 30 days after written notice of such breach is given by Acquiror to the
party committing such breach.  The parties acknowledge that the failure to
obtain the consent of First Union to the Merger or a waiver from First Union of
the acceleration of any Indebtedness that would or could be caused by
consummation of the Merger shall not afford the Acquiror a right of termination
hereunder.

             (ii)         This Agreement may be terminated and the Merger may
be abandoned at any time on or prior to the close of business on October 14,
1996 by the Chairman and Chief Executive Officer or the Chief Financial Officer
of Acquiror by notice in writing to the Corporation if Acquiror determines in
its sole discretion as the result of its legal, financial, environmental and
operational due diligence with respect to the Corporation, that such due
diligence reveals a material adverse change or difference in the financial
condition of the Corporation together with the Corporation Subsidiaries and the
Partnerships, taken as a whole, from that reflected in the consolidated
financial statements of the Corporation set forth in Section 5.9 hereof.
Notwithstanding the foregoing sentence, the Agreement may be terminated and the
Merger may be abandoned at any time on or prior to the close of business on
November 5, 1996 by any such person delivering such notice if Acquiror
determines in its reasonable judgment as a result of its regulatory due
diligence with respect to the Corporation, that such due diligence reveals a
material issue(s) with respect to the regulatory compliance at any one of the
Affiliated Practices or Corporation ASCs.  None of the matters disclosed in the
Corporation Disclosure Letter shall give rise to a right of termination under
this Section 9.4(ii).

         9.5     Effect of Termination and Abandonment.

              (i)         In the event of termination of this Agreement and the
abandonment of the Merger pursuant to this Article 9, no party hereto (or any
of its directors or officers) shall have any liability or further obligation to
any other party to this Agreement except as provided in Section 9.5(ii),
Section 7.8 (subject to Section 9.5(ii)) and Section 10.6 below, and except
that nothing herein will relieve any party from liability for any breach of
this Agreement.

             (ii)         In the event that any person shall have made an
Acquisition Proposal for the Corporation and thereafter the Agreement is
terminated by either party (other than pursuant to the breach of this Agreement
by Acquiror or termination by Acquiror pursuant to Section 9.4(ii)) then the
Corporation, if requested by Acquiror, shall, subject to the provisions set
forth below, on the earlier of January 31, 1997 or the date the Corporation
consummates a transaction with any person who has made an Acquisition Proposal,
pay Acquiror a fee equal to all fees and expenses incurred by Acquiror in
connection with the transactions contemplated by this Agreement as reflected
upon an invoice prepared by Acquiror and delivered to the Corporation





                                      46
<PAGE>   52
and an amount equal to $2,450,000, which amount shall be payable by wire
transfer of same day funds (collectively, the "Break-Up Fee"); provided that no
fee shall be payable to Acquiror pursuant to this Section 9.5(ii) unless and
until (i) any person (other than Acquiror) (an "Acquiring Party") and the
Corporation have entered into a definitive agreement to consummate an
Acquisition Proposal.  Notwithstanding the foregoing in the event that the
Merger has not been consummated on or before November 30, 1996 and failure to
consummate the Merger by that time has not resulted from the action or inaction
of the Corporation (which action or inaction would include entertainment of an
Acquisition Proposal), Acquiror shall not be entitled to any Break-Up Fee;
provided that the November 30, 1996 date shall be subject to extension for up
to two 30-day periods (i) automatically if failure to close has been delayed by
third parties or events not within the control of any party hereto, or (ii) by
mutual written consent of the parties which shall not be unreasonably withheld.

         The Corporation acknowledges that the agreements contained in this
Section 9.5(ii) are an integral part of the transactions contemplated in this
Agreement, and that, without these agreements, Acquiror and Merger Sub would
not enter into this Agreement; accordingly, if the Corporation fails to
promptly pay the amount due pursuant to this Section 9.5(ii), and, in order to
obtain such payment, Acquiror or Merger Sub commences a suit which results in a
final judgment, the non-prevailing party shall pay to the prevailing party its
costs and expenses (including attorneys' fees) in connection with such suit,
together with interest on the amount of the fee at the prime rate of
NationsBank Texas, N.A. in effect on the date such payment was required to be
made.

            (iii)         In the event of termination of this Agreement
pursuant to Section 9.2(ii) hereof, the Corporation shall promptly pay Acquiror
a fee equal to all fees and expenses incurred by Acquiror in connection with
the transactions contemplated by this Agreement as reflected upon an invoice

and vice versa.

         10.10   Waivers.  Except as provided in this Agreement, no action
taken pursuant to this Agreement, including without limitation any
investigation by or on behalf of any party, shall be deemed to constitute a
waiver by the party taking such action of compliance with any representations,
warranties, covenants or agreements contained in this Agreement.  The waiver by
any party hereto of a breach of any provision hereunder shall not operate or be
construed as a waiver of any prior or subsequent breach of the same or any
other provision hereunder.

Exhibits attached hereto and referred to herein and the Corporation Disclosure
Letter and Acquiror Disclosure Letter referred to herein are hereby

of the provisions of this Agreement shall be held or deemed to be inoperative,
unenforceable or invalid as applied to any particular case or in all cases,

invalid in any other case or of rendering any of the other provisions of this
Agreement inoperative, unenforceable or invalid.
