         Section 2.1 Independent Contractors. The Group and Administrator intend
to act and perform as independent contractors, and the provisions hereof are not
intended to create any partnership, joint venture, agency or employment
relationship between the parties. Administrator and the Group agree that the

and ethical aspects of its medical practice. Administrator shall neither
exercise control or direction over the medical methods, procedures or decisions
nor interfere with the physician-patient relationships of the Group, which shall
be maintained strictly between the physicians of the Group, Physician Employees
and/or Physician Extender Employees and their patients.

         Section 2.2 Practice of Medicine. The parties hereto acknowledge that
neither Administrator nor Parent is authorized or qualified to engage in any
activity which may be construed or deemed to constitute the practice of medicine
and that nothing herein shall be construed as the practice of medicine by
Administrator or Parent. To the extent any act or service required of
Administrator is construed or deemed to constitute the practice of medicine,
Administrator is released from any obligation to provide, and the Group shall be
deemed not to have requested Administrator to provide, such act or service
without otherwise affecting the other terms of this Agreement.

         Section 2.3 No Payment or Other Compensation for Referrals. The parties
hereby agree that the benefits to the Group hereunder do not require, are not

                                   ARTICLE III

                    Services to be Provided by Administrator

         Section 3.1 General. Administrator shall provide or arrange for the
services set forth in this Article III, and the costs, fees, expenses and other
disbursements incurred by Administrator or Parent in connection therewith shall
be included in Practice Expenses, except to the extent such costs, fees or
expenses are expressly included in Excluded Practice Expenses or Administrator
Expenses. Administrator is authorized to perform its services hereunder as is
necessary or appropriate for the efficient operation of the Practice, including,
without limitation, performance of some of the business office functions at
locations other than the Practice. Except to the extent necessary to comply with
applicable laws, regulations or professional ethical standards, the Group will
not act in a manner which would prevent Administrator from performing its duties
hereunder and will provide such information and assistance to Administrator as
is reasonably required by Administrator to perform its services hereunder.
Administrator shall cause its employees, to comply with all applicable federal,
state and local laws, rules and regulations in Administrator's provision of
services hereunder.

         Section 3.2         General Administrative Services.

         (a) Exclusive Management Services; Scope of Services. The Group hereby
engages Administrator to serve as its exclusive manager and administrator of
non-medical business services relating to the operation of the Practice, subject
to matters reserved for the Group or referred to the Joint Planning Board as
herein contemplated, and Administrator shall have all necessary authority and
hereby agrees to perform such services. The Group agrees that the purpose and
intent of this Agreement is to relieve the Group to the maximum extent possible
of the administrative, accounting, purchasing, non-physician personnel and other
non-medical business aspects of the Practice. Administrator agrees that the
Group, Physician Employees and Physician Extender Employees, and only the Group,
Physician Employees and Physician Extender Employees, will perform the
professional medical functions of the Practice. Administrator shall have no
authority, directly or indirectly, to perform, and shall not perform, any
professional medical function. Administrator may, however, advise the Group as
to the relationship between the Group's performance of professional medical
functions and the overall administrative and business functions of the Practice
to the extent permitted by applicable law.

         (b)      Billing and Collection.

                  (i) Administrator shall, in the name of and on behalf of the
Group, bill patients, insurance companies, Managed Care Payors, and other
third-party payors and collect all fees for services rendered in connection with
the Practice at the Premises or any Practice Site(s) (including all fees
generated by both the Technical Operations and the Professional Operations), for
services performed outside the Practice for its hospitalized patients, and for
all other professional and Practice services. The Group hereby appoints
Administrator for the term of this Agreement to be its true and lawful
attorney-in-fact, for the following purposes:

                           (A) to bill patients, insurance companies, Managed
Care Payors, and other third-party payors in the Group's name and on its behalf;




                                       8
<PAGE>   14

                           (B) to collect accounts receivable resulting from
such billing not otherwise purchased by Administrator (as provided for in
Section 3.2(e) hereof) in the Group's name and on its behalf;

                           (C) to receive payments on behalf of the Group from
insurance companies, prepayments received from health care plans, Medicare,
Medicaid, Managed Care Payors and all other third-party payors;

                           (D) to ensure the collection and receipt in
Administrator's name and for Administrator's account of all accounts receivable
of the Practice purchased by Administrator, and to deposit such collections in
the Account;

                           (E) to take possession of and endorse in the name of
the Group and deposit into the Deposit Account (and/or in the name of an
individual physician, such payment intended for purpose of payment of
professional fees related to the Practice) any notes, checks, money orders,
insurance payments and other instruments received in payment of accounts
receivable not otherwise purchased by Administrator; and

                           (F) upon the prior consent of the Group, which
consent shall not be unreasonably withheld or delayed, to initiate the
institution of legal proceedings in the name of the Group or a Physician
Employee to collect any accounts and monies owed to the Group or the Physician
Employee, to enforce the rights of the Group or the Physician Employee, as the
case may be, as creditor under any contract or in connection with the rendering
of any service, and to contest adjustments and denials by governmental agencies
(or their fiscal intermediaries) as third-party payors.

                  (ii)    The Group hereby appoints Administrator as its true 
and lawful attorney-in-fact to deposit into the Deposit Account all Professional
Revenues and Technical Revenues collected by Administrator as provided for in
this Section 3.2(b). The Group covenants, and shall cause all Physician
Employees and Physician Extender Employees to covenant, to forward any payments
received with respect to any Professional Revenues or Technical Revenues
generated for services provided by the Group or any of its Physician Employees
and Physician Extender Employees to Administrator for deposit. Administrator
shall have the right to withdraw funds from the Deposit Account and all owners
of the Deposit Account shall execute a revocable standing transfer order (the
"Transfer Order") under which the bank maintaining the Deposit Account shall
periodically transfer the entire balance of the Deposit Account to a separate
bank account owned solely by Administrator (the "Administrator Account"). The
Group and Administrator hereby agree to execute from time to time such documents
and instructions as shall be required by the bank maintaining the Deposit
Account and mutually agreed upon to effectuate the foregoing provisions and to
extend or amend such documents and instructions. Any action by the Group that
materially interferes with the operation of this Section, including but not
limited to, any failure to deposit or to have Administrator deposit any
Professional Revenues and/or Technical Revenues into the Deposit Account, any
withdrawal of any funds from the Deposit Account not authorized by the express
terms of this Agreement or any other written agreement executed by each of the
parties, or any revocation of or attempt to revoke the Transfer Order (otherwise
than upon expiration or termination of this Agreement), will constitute a breach
of this Agreement and will entitle Administrator, in addition to any other
remedies it may have at law or in equity, to seek a court ordered assignment of
the rights provided to Administrator pursuant to subparagraph (i) above.

                  (iii)    All monies shall be accounted for by Administrator as
being distinctly





                                       9

attributable to the Group. The Group may perform the functions or exercise the
rights set forth in this Section 3.2(b) only with the prior written consent of
Administrator. The Group shall execute such documents in form and substance as
approved by Administrator and its legal counsel to permit Administrator to
exercise the rights and powers granted to Administrator pursuant to this Section
3.2(b). The Group shall cooperate with, and at the request of Administrator
shall provide reasonable assistance to, Administrator with the functions set
forth herein. In the performance of the services described in this Section
3.2(b), Administrator shall use commercially reasonable efforts to collect such
professional fees and shall comply with all applicable Managed Care Contracts
and all applicable laws, rules and regulations.

         (c) Accounting. Administrator shall administer and maintain the

representatives shall have the right to review all financial books and records

information shall be provided by Administrator to the Group in any media
reasonably requested upon reimbursement of Administrator's actual cost.

         (d) Cash Management. Administrator shall manage the cash and cash
equivalents of the Group and Administrator shall be entitled (and is hereby
authorized) to transfer such cash to the account of Administrator and to use
such cash for purposes as Administrator deems appropriate, subject to and
consistent with the terms and provisions of this Agreement.

         (e) Purchase of Accounts Receivable and Right of Offset. Effective each
business day of the month and subject to applicable law, Administrator shall
purchase all accounts receivable of the Group arising during the day or days
just ended and shall make payment to Group therefor or offset, without further
notice or authorization, sums owed Administrator by Group as the parties have
agreed herein. The purchase price shall be an amount equal to the aggregate face
amount of the accounts receivable being sold less contractual adjustments and
estimated allowances for bad debt as determined from time to time based on
recent historical collection experience of one year or less. Administrator shall
make appropriate adjustments for bad debt and contractual allowances following
the close of each fiscal quarter of the Administrator.

         (f) Obligations of Administrator. Administrator shall supply to the
Group all ordinary, necessary or appropriate services for the efficient
operation of the Practice, including without limitation, clerical, accounting,
purchasing, payroll, legal, bookkeeping and computer services, information
management, preparation of Tax Returns, printing, postage and duplication

Practice Expenses. Administrator shall prepare monthly unaudited accrual or
cash-basis (as designated by the Group) financial statements for the Group

may elect to have an audit conducted with respect to such financial statements
by an accounting firm selected by Group in its sole discretion, in which case

and/or Parent's cash or other resources including the assumption of any Practice
Expenses or liabilities incurred or reasonably expected to be incurred as a

                  (i) Budgeted Expenditures. All budgeted capital expenditures
and improvement projects shall be subject to final review and approval by the
Joint Planning Board prior to the making of any actual expenditure. Such review

Employees employed at the time the capital budget for such Group for the
applicable year is determined (provided, however, that such aggregate amount
shall not exceed $100,000 for any calendar year) must be approved by the Board
of Directors of Parent or by any committee specifically designated by the Board
of Directors of Parent for such purposes.

         (c)      Capital Improvements and Expansion. Subject to Section 3.5(b),
any site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and
approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

         Section 3.6 Personnel. Administrator shall provide non-physician
professional support (other than Physician Extender Employees) including,
without limitation, nurses, technologists, physicists and administrative,
clerical, secretarial, bookkeeping and collection personnel as is reasonably
necessary for the efficient conduct of the Practice's operations. All such
personnel shall be duly qualified by education or experience for their
respective positions and shall possess all licenses which may be required by
law. Such personnel shall be employees of Administrator, and Administrator shall
determine and cause to be paid the salaries and benefits of all such personnel.
Such personnel shall be supervised by and comply with the directions and orders
of Administrator, except as otherwise required by applicable law. If the Group
is dissatisfied with the services of any such personnel who provide services
primarily for the Practice at the Premises, the Group shall consult with
Administrator, and Administrator shall in good faith determine whether the
performance of that employee could be brought to acceptable levels through
counsel and assistance, or whether such employee should be considered for
termination. If Administrator determines to retain such employee and the Group
is still dissatisfied with the services provided by such employee after a
reasonable period of time, Administrator shall either relocate such employee or
otherwise cease to utilize such employee in providing services to the Practice
hereunder. Administrator shall maintain established working relationships
wherever possible and Administrator shall make every effort consistent with
sound business practices to honor the specific requests of the Group with regard
to the assignment of Administrator's employees.

         Section 3.7 Inventory and Supplies. Administrator shall order, purchase
and provide to the Group on a timely basis inventory and supplies, and such
other ordinary, necessary or appropriate materials which are requested by the
Group and which the Group shall reasonably determine to be necessary in the
operation of the Practice on the same terms commercially available to
Administrator. Such inventory, supplies and other materials shall be included in
Practice Expenses at their cost to Parent or Administrator, as the case may be.

         Section 3.8 Advertising and Public Relations. In consultation with the
Joint Planning Board, Administrator shall implement (and design where requested)
an appropriate local public relations or advertising program on behalf of the
Practice, with appropriate emphasis on public awareness of the availability of
services at the Practice. Prior to publication or distribution of such marketing
or public relations material or information, Administrator shall submit such
material to the Group for its review and approval, which shall not be
unreasonably withheld. Administrator shall also design and implement all
national or other non-local public relations or advertising programs on behalf
of the Practice, the cost of which shall be included in Administrator Expenses,
except to the extent such national programs are reasonably designed to replace
or supplement the marketing benefits derived from local public relations or
advertising programs, in which case, a pro rata share of such costs will be
included in Practice Expenses as determined by the Joint Planning Board. The
parties hereto agree that all public relations and advertising programs shall be
conducted in compliance with applicable standards of medical ethics, laws and
regulations.

         Section 3.9 Quality Assurance. Subject to Article II, Administrator
shall assist the Group in fulfilling its obligations to its patients to maintain
a high quality of medical and professional services. Any expenses that are
related to the overall maintenance of Administrator's quality assurance program
shall be included in Administrator Expenses; provided, however, that any
expenses related to such program that are incurred for services provided solely
for the direct benefit of the Practice shall be included in Practice Expenses.

         Section 3.10 Other Consulting and Advisory Services. Administrator will
provide such consulting and other advisory services as reasonably requested by
the Group in all areas of the Group's business functions, including, without
limitation, financial planning, acquisition and expansion strategies,
development of long-term business objectives and other related matters.

         Section 3.11 Events Excusing Performance. In the event of strikes,
lock-outs, calamities, acts of God, unavailability of supplies or other events
over which Administrator has no control, Administrator shall not be liable to
the Group for failure to perform any of the services required hereunder and the
Group shall not have the right to terminate this Agreement pursuant to Section
10.3(b), for so long as such events continue and for a reasonable period of time
thereafter; provided however that if such events continue and Administrator is
not able to perform any material portion of the services required hereunder for
a period of 120 consecutive days or more, either Administrator or Group may
terminate this Agreement by written notice to the other.

                                   ARTICLE IV

                            Obligations of the Group

         Section 4.1 Employment of Physician Employees and Physician Extender
Employees. Except as set forth in Article V, the Group shall have complete
control of and responsibility for the hiring, compensation, supervision,
training, evaluation and termination of its Physician Employees and Physician
Extender Employees. The Group shall conduct an appropriate and reasonable due
diligence review in connection with the hiring of any physician or the
acquisition of any physician group or practice. Although Administrator may
provide payroll and other related services to the Group, the Group shall be
solely responsible for the payment of such Physician Employees' and Physician
Extender Employees' salaries and wages, payroll taxes and all other taxes now or
hereafter applicable to their employment. The Group and its Physician Employees
and Physician Extender Employees shall not have any claim under this Agreement
or otherwise against Administrator or Parent for workers' compensation,
unemployment compensation or Social Security benefits, all of which shall be the
sole responsibility of the Group. The Group shall only employ or contract with
licensed physicians or other persons meeting applicable credentialing guidelines
established by the Group after consultation with the Joint Planning Board. The
Group shall cooperate in the obtaining and retaining of professional liability
insurance by ensuring that its Physician Employees and Physician Extender
Employees, and other employees who may have malpractice exposure or liability,
are insurable and by participating in an ongoing risk management program.

         Section 4.2 Professional Services. The Group shall provide professional
services to its patients in compliance at all times with ethical standards,
laws, rules and regulations applicable to the operations of the Practice, the
Physician Employees and Physician Extender Employees. The Group shall ensure
that each Physician Employee and each Physician Extender Employee has all
required licenses, credentials, approvals or other certifications to perform his
or her duties and services for the Practice and, in the event that the Group
becomes aware of any disciplinary actions or medical malpractice actions
initiated against any Physician Employee or Physician Extender Employee, the
Group shall promptly inform Administrator of such action and the underlying
facts and circumstances. If required by applicable law, any state or federal
regulatory agency or any contractual obligations, the Group shall carry out a
program to monitor the quality of medical care practiced at the Practice;
provided, however, that the preceding language shall not limit the Group's
obligation to participate in or comply with any programs established by
Administrator or Parent for purposes of ensuring that the Group complies with
applicable law. The Group shall employ Physician Employees and Physician
Extender Employees as is necessary to provide efficient medical care to patients
of the Practice.

         Section 4.3 Medical Practice. The Group shall use and occupy the
Premises exclusively for the practice of medicine and for providing other
related services and products. Unless otherwise approved in writing in advance
by Administrator, which approval shall not be unreasonably withheld or delayed,
it is expressly acknowledged by the parties hereto that the professional medical
practice or practices conducted at the Premises shall be conducted solely by
Physician Employees, and, no other physician or medical practitioner shall be
permitted to use or occupy the Premises; provided, however, if any test or
procedure is required to be performed jointly with another physician who is not
a Physician Employee or Physician Extender Employee, then such physician may use
and occupy the Premises for purposes of performing such procedure or test so
long as the Group receives usual and customary fees in connection with such
procedure or test. The Group shall be solely and exclusively in control of all
aspects of the practice of medicine and the delivery of medical services at the
Group's facilities and at such outpatient surgery centers, acute care hospitals
and other facilities as the Group may deem appropriate from time to time. The
rendition of all






                                       16
<PAGE>   22

professional medical services, including, but not limited to, diagnosis,
treatment, therapy, the prescription of medicine and drugs, and the supervision
and preparation of medical reports shall be the sole responsibility of the
Group. From time to time the Group, after consultation with the Joint Planning
Board, will adopt and implement fee schedules for (i) non-prepaid patients which
shall be reasonable in relation to fees generally being charged in the same or
similar market areas and (ii) for all rebillings and recovery items on prepaid
Managed Care Contracts which are authorized and permitted by such contracts. A
copy of such agreements and any amendment thereto shall be provided to
Administrator for review no later than thirty (30) days prior to the proposed
effective date thereof.

         Section 4.4 Group's Internal Matters. The Group shall be responsible
for matters involving its corporate governance, employees and similar internal
matters, including, but not limited to, preparation and contents of such reports
to regulatory authorities governing the Group that the Group is required by law
to provide, distribution of professional fee income among the Group Physician
Stockholders, disposition of the Group's property and stock (subject to any
restrictions contained herein), hiring and firing of its employees, licensing
and implementing all compliance plans and procedures as described in Section
4.6. Except for the expenses attributable to the distribution of professional
fee income among the Group Physician Stockholders, which will be included in
Excluded Practice Expenses, the costs incurred in connection with the foregoing
matters shall be Practice Expenses.

         Section 4.5 Name. Administrator agrees that the Group shall be entitled
to use on a non-exclusive and non-transferable basis for the term of this
Agreement the names set forth on Schedule 4.5 as may be necessary or appropriate
in the performance of the Group's services and obligations hereunder.

         Section 4.6 Compliance with Laws. The Group shall, and shall use its
reasonable efforts to cause the Physician Employees, Physician Extender
Employees and other employees of the Group to, comply with all applicable
federal, state and local laws, rules, regulations and restrictions in the
conduct of the Practice's business. Without limiting the generality of the
foregoing, the Group shall comply and shall cause each Physician Employee,
Physician Extender Employee and other employee of the Group to comply, with all
laws applicable to the operation of the Practice in the generation,
transportation, treatment, storage, disposal or other handling of radioactive,
medical, biological or hazardous materials or waste, and the Group shall not,
and shall use its reasonable efforts to prohibit any Physician Employee,
Physician Extender Employee and any employee of the Group from:

         (a) entering into any contract, lease, agreement or arrangement,
including, but not limited to, any joint venture or consulting agreement, to
provide services, lease space, lease equipment or engage in any other venture or
activity with any physician, hospital, pharmacy, home health agency or other
person or entity which is in a position to make or influence referrals to, or
otherwise generate business for, the Practice, if such transaction is in
violation of any applicable law, rule or regulation;

         (b) 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 from a Managed Care Payor or any other Payor;

         (c) knowingly and willfully making or causing to be made a false
statement or representation of a material fact for use in determining rights to

<PAGE>   23

         (d) failing to disclose knowledge by a claimant 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 intent to fraudulently secure such
benefit or payment;

         (e) knowingly and willfully paying, 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; and

         (f) referring a patient for health services or products to or providing
health services to a patient upon a referral from an entity or person with which
the physician or an immediate family member has a financial relationship, other
than as permitted by exceptions set forth in federal or state anti-referral laws
or regulations; and

         (g) undertaking any action that is not in accord with the regulatory
compliance plans, policies and manuals developed by or in conjunction with
Administrator.

         Section 4.7 Ancillary Services. Except as set forth in Section 3.4(b),
the Group shall not acquire, establish or commence the operation of any
satellite location, medical office, imaging center, health maintenance
organization, preferred provider organization, exclusive provider organization
or similar entity or organization established or operated by the Group after the
date hereof without the prior written consent of Administrator.

         Section 4.8 Premises and Personal Property. The Group shall use its
best efforts to prevent damage, excessive wear and tear, and malfunction or
other breakdown of the Premises and Personal Property or any part thereof by the
Physician Employees and Physician Extender Employees or other employees of the

of any and all necessary replacements, repairs or maintenance to any of the
Premises or Personal Property and any failures of equipment of which it becomes

the express written consent of Administrator, which consent shall not be
unreasonably withheld.

         Section 4.10 Events Excusing Performance. In the event of strikes,
lock-outs, calamities, acts of God, unavailability of supplies or other events
over which the Group has no control, the Group shall not be liable to
Administrator, Parent or their Affiliates for failure to perform any of its
obligations required hereunder as may be materially restricted by any such event
and Administrator shall not have the right to terminate this Agreement pursuant
to Section 10.4(a), for so long as such events continue and for a reasonable

                                    ARTICLE V

                              Joint Planning Board

         Section 5.1 Formation and Operation of the Joint Planning Board.

         (a) The parties hereto shall establish the Joint Planning Board which
shall be responsible for developing long-term strategic planning objectives and
management policies for the overall operation of the Practice and shall
facilitate communication and interaction between Administrator and the Practice.
The Joint Planning Board shall consist of no less than three (3) or more than
six (6) members. Administrator shall designate, in its sole discretion, two (2)
members of the Joint Planning Board, who shall serve at the pleasure of
Administrator and who may be removed or replaced by Administrator at any time.
The Group shall designate, in its sole discretion, no less than one (1) or more
than four (4) members of the Joint Planning Board, who shall serve at the
pleasure of the Group and who may be removed and replaced by the Group at any
time. Each member appointed by Administrator shall be entitled to one (1) vote
per member, and each member appointed by the Group shall be entitled to that
number of votes equal to the quotient determined by dividing (x) two (2) votes
by (y) the number of members designated by the Group to the Joint Planning
Board. The act of the members holding a majority of the voting power of the
Joint Planning Board shall be the act of the Joint Planning Board.

         (b) Each member of the Joint Planning Board shall have the right to
vote on every matter either in person, by telephone, by written consent or by
one or more agents, who are also members of the Joint Planning Board, authorized
by a written proxy signed by the member and filed with the Joint Planning Board.
A proxy shall state that it either shall be voted for or against a specific
matter or matters identified in the proxy or shall be voted identically to the
vote of the agent specified in the proxy on any and all matters that may come
before and be voted on by the Joint Planning Board. A validly executed proxy
which does not state that it is irrevocable shall continue in full force and
effect unless (i) revoked by the member executing it, before the vote pursuant
to that proxy, by a writing delivered to the Joint Planning Board stating that
the proxy is revoked, or by a subsequent proxy executed by, or attendance at the
meeting and voting in person by, the member executing the proxy; or (ii) written
notice of the death or incapacity of the maker of that proxy is received by the
Joint Planning Board before the vote pursuant to that proxy is counted;
provided, however, that no proxy shall be valid after the expiration of eleven
(11) months from the date of the proxy, unless otherwise provided in the proxy.

         Section 5.2 Duties and Responsibilities of the Joint Planning Board.
The Joint Planning Board shall advise the Group on the following matters:

         (a) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and
approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

         (b) Annual Budgets. The Joint Planning Board shall collaborate with
Administrator on all annual capital and operating budgets prepared by
Administrator, as set forth in Section 3.5(b) and after the annual capital and
operating budgets have been approved as provided in Section 3.5(b), no
substantial






                                       19
<PAGE>   25

changes may be made in such budgets without the approval of the Joint Planning
Board. For purposes of this Section 5.2, substantial means any change
individually or in the aggregate which would result in a change in excess of
five percent (5%) to the annual capital or operating budgets.

         (c) Advertising. The Joint Planning Board shall consult with
Administrator on all local advertising and other marketing of the services
performed by or for the Group.

         (d) Patient Fees. As a part of the annual operating budget, in
consultation with and upon recommendation of the Joint Planning Board, the Group
shall review and adopt the fee schedule for all professional services rendered
by the Practice.

         (e) Ancillary Services and Fees. The Joint Planning Board shall approve
Practice-provided non-medical ancillary services (including, without limitation,
fees for technical services which do not generate Professional Revenues) based
upon the pricing, access to, and quality of such services and shall review and
adopt the fee schedule for all ancillary services.

         (f) Provider and Payor Relationships. Subject to Section 3.7, decisions
regarding the establishment or maintenance of relationships with institutional
health care providers and payors shall be approved by the Group after
consultation with the Joint Planning Board.

         (g) Strategic Planning. The Joint Planning Board shall develop a plan
which depicts the strategic direction of the Practice, as updated from time to
time. Such plan will, among other things, identify opportunities, objectives,
and the resources required to effect such plan.

         (h) Capital Expenditures. The Joint Planning Board shall determine the
priority of capital expenditures in accordance with Section 3.5(b) hereof.

         (i) Provider Hiring. The Joint Planning Board shall consult with the
Group to recommend the number and type of Physician Employees and Physician
Extender Employees required for the efficient operation of the Practice.

         (j) Non-Physician Personnel. The Joint Planning Board shall consult
with Administrator to recommend the number and type of non-physician employees
required for the efficient operation of the Practice.

         Section 5.3 Acts of the Joint Planning Board. Except as otherwise
specifically provided herein, the act of the members holding a majority of the
voting power of the Joint Planning Board shall be the act of the Joint Planning
Board. The Group agrees that, unless the following are approved in advance by
the Joint Planning Board and such act of the Joint Planning Board includes the
approval by both of the members designated by Administrator, it shall take no
action or implement any decision that would (i) require Administrator to expend
funds or incur obligations beyond those set forth under Sections 3.5 or 5.2 of
this Agreement; (ii) have a material adverse effect on the amount of
Administrator's management fee under Article VII; or (iii) otherwise have a
material adverse effect on Administrator's financial interests under this
Agreement. Except as provided in the prior sentence, the Group and Administrator
hereby agree to be bound by the act of the Joint Planning Board if such act was
approved by the members holding at least a majority of the voting power of the
Joint Planning Board. No action of the Joint Planning Board shall be effective
unless authorized by the members holding a majority of the voting power of the
Joint Planning Board present or represented by proxy at the applicable meeting.
In the event that a matter cannot





                                       20
<PAGE>   26

be resolved by the Joint Planning Board due to a tie vote, and no compromise can
be reached, then either (x) the Board of Directors of Parent or (y) a committee
designated by the Board of Directors of Parent containing at least one (1)
physician member will make a final determination on the matter in dispute
provided that both the Group and Administrator shall have had an opportunity to
make a presentation to the Board of Directors of Parent or a committee thereof,
as applicable. A quorum of the Joint Planning Board shall consist of the members
holding a majority of the voting power of the Joint Planning Board, present in
person, by telephone, or by proxy and the quorum must remain for the duration of
the meeting.

         Section 5.4 Joint Planning Board Meetings. Meetings of the Joint
Planning Board may be held by telephone or similar communication equipment so
long as all members participating in a meeting can hear and speak to each other.
The Joint Planning Board shall prepare and maintain written minutes of all
meetings and shall provide a copy of the minutes to the members within fifteen
(15) business days following each meeting.

         (a)      Regular Meetings. The Joint Planning Board shall hold not less
than four (4) regular meetings each year, at such specific times and places as
the members may determine.

         (b)      Special Meetings. A special meeting of the Joint Planning
Board may be called by fifty percent (50%) of the votes.

         (c)      Notice Requirement. A member calling a special meeting must
provide all other members with ten (10) days' advance written or telephonic
notice. Notice must be given or sent to the member's address or telephone number
as shown on the records of the Joint Planning Board. Notice may be delivered
directly to each member or to a person at the member's principal place of
business who would reasonably be expected to communicate that notice promptly to
the member.

         (d)      Waiver of Notice Requirement.

                  (i) Written Waiver, Consent or Approval. Notice of a special
meeting need not be given to any member who, either before or after the meeting,
signs a waiver of notice or a written consent to the holding of the special
meeting, or an approval of the minutes of the special meeting. Such waiver,
consent or approval need not specify the purpose of the special meeting. All
such waivers, consents, and approvals shall be filed with the Joint Planning
Board records or made a part of the minutes of the special meetings.

                  (ii) Failure to Object. Notice of special meeting need not be
given to any member who attends the special meeting and does not protest before
or at the commencement of the special meeting such lack of notice.

                  (iii) Quorum. The smallest number of members that hold votes
that exceed fifty percent (50%) of all voting power shall constitute a quorum of
the Joint Planning Board.

                  (iv) Proxies. The Joint Planning Board shall provide for the
use of proxies, telephonic conference calls, written consents or other
appropriate methods by which the full participation of the Group members and
Administrator members can be assured.

                                   ARTICLE VI

                              Restrictive Covenants

         The parties recognize that the services to be provided by Administrator
hereunder shall be feasible only if the Group operates active Professional
Operations and Technical Operations to which the physicians associated with the
Practice devote their full medical time and attention. Accordingly, the parties
hereto agree as follows:

         Section 6.1         Restrictive Covenants of the Group.

         (a)      Noncompetition. During the term of this Agreement, the Group 
shall not, without the prior written consent of Administrator, (i) establish,
operate or provide professional radiology, radiation oncology or diagnostic
services at any medical office, practice or other health care facility (other
than a Practice Site) providing services similar to those provided by the
Practice or enter into an agreement with any third party payor to provide such
services, (ii) enter into any other management or administrative services
agreement or other arrangement with any other person or entity (other than with
Administrator) for purposes of obtaining management, administrative or other
support services, or (iii) engage or participate in any business which engages
in competition with the business conducted by the APPM Group anywhere within 15
miles of any location at which any member of the APPM Group conducts business.

         (b)      Covenant Not to Solicit. During the term of this Agreement and
for twenty-four (24) months following the termination of this Agreement, the
Group shall not, without the prior written consent of Administrator: (i) unless
the Group acquires the Practice Assets pursuant to Article X, directly or
indirectly recruit or hire, or induce any party to recruit or hire any person
who is an employee of, or who has entered into an independent contractor
arrangement with, any member of the APPM Group; (ii) directly or indirectly,
whether for itself or for any other person or entity, call upon, solicit, divert
or take away, or attempt to solicit, call upon, divert or take away any
customers, business, or clients of any member of the APPM Group; (iii) directly
or indirectly solicit, or induce any party to solicit, any contractors of any
member of the APPM Group, to enter into the same or a similar type of contract
with any other party; or (iv) disrupt, damage, impair or interfere with the

         (c)      Engagement of Administrator. If (i) this Agreement is 
terminated pursuant to Section 10.4(a) or (c), and (ii) the Group does not
acquire the Purchase Assets as provided in Article X, then if the Group
establishes, operates or provides professional services at any office, practice,
diagnostic imaging center, hospital or other health care facility providing
services substantially similar to those provided by the Practice pursuant to
this Agreement anywhere within 15 miles of any location of any Practice Site(s),
the Group or any successor thereto shall engage Administrator as the sole and
exclusive manager and administrator of the nonprofessional functions and
services of such other office, practice, hospital or health care facility on the
same terms and conditions as contained herein.

         (d)      Administration's Obligations Regarding Proprietary Interest.

                  (i) Acknowledgement of Proprietary Interest. Administrator,
Parent or their Affiliates hereto recognize the proprietary interest of the
Group in any Confidential and Proprietary Information (as hereinafter defined).
Administrator, Parent and their Affiliates acknowledge and agree that any and
all Confidential and Proprietary Information of the Group ("Group's Confidential

otherwise acquired by Administrator, Parent and their Affiliates during the term
of this Agreement shall be the property of the Group. Administrator, Parent and






                                       22
<PAGE>   28

their Affiliates further acknowledge and understand that disclosure of any of
Group's Confidential and Proprietary Information will result in irreparable
injury and damage to the Group. As used herein, "Group's Confidential and

         (f)      Third Party Beneficiaries. The members of the APPM Group not
party to this Agreement are hereby specifically made third party beneficiaries
of this Section 6.1, with the power to enforce the provisions hereof.

         Section 6.2 Restrictive Covenants. The Group shall obtain and enforce
formal agreements with each Physician Employee who is either (i) a Group
Physician Stockholder or (ii), to the extent permitted under applicable law, a
Full-time Physician Employee which each contain certain restrictive covenants
thereof pertaining to covenants not to compete and/or solicit with and not to
divulge the Confidential and Proprietary Information of any member of the APPM
Group or the Practice (the "Restrictive Covenants"). Except as otherwise
approved by the Joint Planning Board, each Group Physician Stockholder or
Full-time Physician Employee shall agree, during the term of his/her employment
or contractor agreement with the Practice and for a period of twenty-four (24)
months after any termination





                                       25
<PAGE>   31

of such agreement: (i) not to establish, operate or provide professional
radiology services at any office, practice, hospital or health care facility
providing services substantially similar to those provided by the Practice
pursuant to this Agreement within 15 miles of any location of any Practice
Site(s) and (ii) to be bound by non-solicitation, noncompetition and
nondisclosure of confidential/proprietary information and engagement of
Administrator covenants similar to those applicable to the Group as contained in
Section 6.1 hereof. Except as otherwise approved by the Joint Planning Board,
each Group Physician Stockholder or Full-time Physician Employee shall agree
that during the term of his/her employment or contractor agreement with the
Group (w) not to practice radiological medicine other than at the Premises or
such other location or Practice Site(s) as approved by the Joint Planning Board;
(x) to devote substantially all of his or her professional time, effort and
ability to the Practice; (y) to request in writing and receive in writing prior
approval from the Joint Planning Board to engage in any outside medical
activities; and (z) to turn over to the Practice, to be included in Professional
Revenues attributed to the Practice, any income derived by such Group Physician
Stockholder or Full-time Physician Employee from any outside medical activity or
related source including, but not limited to, the following medically-related
activities: teaching, consulting, medical research, inventions developed
utilizing the Group's or the Practice's time and material, testimony for
litigation, and insurance examinations. The Group shall not amend, alter or
otherwise change any term or provision of any Stockholder Employment Agreement
or Physician Employee Employment Agreement relating to the foregoing covenants
in this Section 6.2 without the prior written consent of Administrator;
notwithstanding the foregoing, any such amendment, alteration or change shall
not be inconsistent with the terms or provisions of this Agreement. Following
termination of this Agreement, the Group shall not amend, alter or otherwise
change any term or provision of the Restrictive Covenants, unless such
provisions are no longer in force and effect pursuant to the terms of the
applicable Stockholder Employment Agreement or Physician Employee Employment
Agreement at the time of termination of this Agreement. In the event the
Purchase Assets are acquired by the Group pursuant to Article X, the obligation
of the Group to enforce Restrictive Covenants shall be limited to enforcement of
non-solicitation and nondisclosure of confidential/proprietary information
covenants.

         Section 6.3 Enforcement of Restrictive Covenants and Other Provisions.
The Group shall enforce the Stockholder Employment Agreements and, to the extent
permitted under applicable law, the Physician Employee Employment Agreements,
including, without limitation, the Restrictive Covenants. The costs and expenses
of such enforcement shall be included in Professional Expenses and all damages
and other amounts recovered thereby shall be included in Professional Revenues.
In the event that, after a request by Administrator, the Group does not pursue
any remedy that may be available to it by reason of a breach or default of the
Restrictive Covenants or any other provision of the Stockholder Employment
Agreements and, to the extent permitted under applicable law, the Physician
Employee Employment Agreements, upon the request of Administrator, the Group
shall assign to Administrator such causes of action and/or other rights it has
related to such breach or default and shall cooperate with and provide
reasonable assistance to Administrator with respect thereto; in which case, all
costs and expenses incurred in connection therewith shall be borne by
Administrator and shall be included in Administrator Expenses, and Administrator
shall be entitled to all damages and other amounts recovered thereby. In the
event the Purchase Assets are acquired by the Group pursuant to Article X, the
obligation of the Group to enforce Restrictive Covenants shall be limited to
enforcement of non-solicitation and nondisclosure of confidential/proprietary
information covenants.

         Section 6.4 Remedies. Administrator and the Group acknowledge and agree
that a remedy at law for any breach or attempted breach of the provisions of
this Article VI shall be inadequate, and therefore, either party shall be
entitled to specific performance and injunctive or other equitable relief in the
event of any such breach or attempted breach, in addition to any other rights or
remedies available to either






                                       26
<PAGE>   32

party at law or in equity. Each party hereto waives any requirement for the
securing or posting of any bond in connection with the obtaining of any such
injunctive or other equitable relief. If any provision of the Restrictive
Covenants or this Article VI relating to the restrictive period, scope of
activity restricted and/or the territory described therein shall be declared by
a court of competent jurisdiction to exceed the maximum time period, scope of
activity restricted or geographical area such court deems reasonable and
enforceable under applicable law, the time period, scope of activity restricted
and/or area of restriction held reasonable and enforceable by the court shall
thereafter be the restrictive period, scope of activity restricted and/or the
geographical area applicable to such provision of the Restrictive Covenants or
this Article VI. The invalidity or non-enforceability of any provision of the
Restrictive Covenants or this Article VI in any respect shall not affect the
validity or enforceability of the remainder of the Restrictive Covenants or this
Article VI or of any other provisions of this Agreement.

         Section 6.5 Condition Precedent to Release of Obligations. In the event
a Group Physician Stockholder or Full-time Physician Employee terminates his/her
employment agreement with the Group, the Group shall be entitled to release
(with the consent of Administrator in its sole and absolute discretion) such
Group Physician Stockholder or Full-time Physician Employee from the restrictive
covenants contained in Section 6.2, above. In the event the Group elects to
release such Group Physician Stockholder or Full-time Physician Employee, the
Group hereby covenants that it shall obtain a formal agreement between each
Group Physician Stockholder or Full-time Physician Employee, as the case may be,
and Administrator which provides that, for a period of two (2) years following
termination of any employment agreement with the Group, such Group Physician
Stockholder or Full-time Physician Employee agrees to (a) engage Administrator
as the sole and exclusive manager and administrator of the non-medical functions
and services of said Group Physician Stockholder's or Full-time Physician
Employee's medical practice and (b) pay to Administrator the identical amount of
revenues paid by the Group to the Administrator attributable to such Group
Physician Stockholder or Full-time Physician Employee derived from such Group
Physician Stockholder's or Full-time Physician Employee's performance of
professional medical services within 15 miles of any Practice Site.

         Section 6.6         Service Area Rights and Obligations.

         (a) Primary Service Area. During the term of this Agreement and within
any Primary Service Area, Parent, Administrator or their Affiliates shall not,
without the prior consent of the Group, (i) acquire or lease the non-medical
assets (through an asset acquisition, merger or other consolidation or
otherwise) of any Radiologist, group of Radiologists or professional corporation
or association (or other professional entity) whose owners are Radiologists,
(ii) acquire any imaging center where, within a reasonable time period following
such acquisition, the Group will not be entitled to provide professional
Radiology services for such imaging center, or (iii) contract to provide
management and administrative services similar to those provided under this
Agreement to any Radiologist, group of Radiologists or professional corporation
or association (or other professional entity) whose owners are Radiologists.
Following a request for consent by Administrator, Parent or their Affiliates
hereunder, the Group shall respond upon the earlier of (i) thirty (30) days from
receipt of such request and all other necessary information related thereto or
(ii) one-half of the time during which Administrator, Parent or their Affiliates
must respond. In the event the Group, Parent, Administrator or their Affiliates
acquire a Professional Service Opportunity, the Group shall accept such
Professional Service Opportunity and shall perform any and all professional
Radiology services that are reasonably required at such location(s) in
accordance with the terms and provisions of this Agreement; provided (x) that
the professional reimbursement for such services is reasonable in relation to
the overall market environment and work effort required and (y) the Group shall
not be required to employ any Radiologist previously associated with such
Professional Service Opportunity.





                                       27
<PAGE>   33


         (b) Secondary Service Area. During the term of this Agreement and
within any Secondary Service Area, Parent, Administrator or their Affiliates
shall first offer to the Group any New Professional Service Opportunity;
provided, however, that this provision shall not be applicable to any merger of
a Radiologist, group of Radiologists or professional corporation or association
(or other professional entity) whose owners are Radiologists with the Group.
Administrator shall give notice (the "Administrator Notice") to the Group
describing the New Professional Service Opportunity. Within the earlier of (i)
thirty (30) days or (ii) one-half of the time during which the Administrator,
Parent or their Affiliates must respond to an offer described in the
Administrator's Notice, the Group shall provide notice to Administrator notice
stating whether or not the Group elects to accept or reject the New Professional
Service Opportunity, which election shall be binding on the Group. If the Group
does not elect to exercise the right or fails to provide notice to Administrator
within the time frame herein provided, Administrator shall be released from the
right of first offer with respect to that particular New Professional Service
Opportunity.

         (c) Determination of Primary and Secondary Service Area. The existence
and location of each of the Group's Primary Service Areas and Secondary Service
Areas shall be determined each time the Group, Parent, Administrator or their
Affiliates propose an acquisition, management relationship, Professional Service
Opportunity or New Professional Service Opportunity as contemplated in
subsections (a) and (b) above.

         (d) Dispute Resolution. Any disputes regarding the interpretation of
the provisions of this Section 6.6 shall be referred to and decided by the Joint
Planning Board as provided in Section 5.3 of this Agreement.

         (e) Definitions. The definitions utilized in connection with this
Section 6.6 shall have the following meanings:

         "New Professional Service Opportunity" shall mean a Professional
Service Opportunity pursuant to which the Group or any other member of an APPM
Group managed by Parent, Administrator or their Affiliates is not currently
providing professional Radiology services.

         "Primary Service Area" shall mean that area within a five (5) mile
radius from any imaging center owned, operated or managed by Administrator,
Parent or their Affiliates for which the Group provides professional Radiology
services or any hospital at which on-site professional Radiology services are
then provided by Physician Employee(s) or Physician Extender Employee(s) of the
Group.

         "Professional Service Opportunity" shall mean any opportunity to
perform professional Radiology services for any hospital, hospital system or
imaging center under a formal agreement with such entity.

         "Radiologist" shall mean and include both radiologists and radiation
oncologists.

         "Radiology" shall mean and include diagnostic imaging, interventional
radiology and radiation oncology services.

         "Secondary Service Area" shall mean that area which extends five (5)
miles beyond the boundary of any Primary Service Area.

         Section 6.7 Survival of Certain Covenants. If this Agreement is
terminated pursuant to






                                       28
<PAGE>   34

Section 10.4(a),(b) or (c), the provisions of Section 6.2 and Section 6.3 shall
survive such termination if the actions or events giving rise to a breach of the
Restrictive Covenants or other provisions occurred prior to such termination. If
the Agreement is terminated pursuant to the preceding sentence, all of the
provisions of Section 6.1 shall survive. However, regardless of the reason for
termination, or upon expiration of this Agreement, the provisions of Section
6.1(d),(e),(f) and (g) shall survive such termination or expiration indefinitely
unless otherwise expressly limited as to a period of time.

         Section 6.8 Definition. The term "Full-time Physician Employee" as used
in Sections 6.2 and 6.5 of this Article VI only, shall mean a Full-time
Physician Employee who shall have been employed by the Group for two (2) years;
provided, that such Full-time Physician Employee shall enter into a written
agreement at the commencement of the later of (i) his/her employment or (ii) the
Acquisition, which includes the provisions set forth in Sections 6.2 and 6.5,
above, and acknowledges his/her understanding that such provisions will be
enforceable against such Full-time Physician Employee following such two (2)
year period. Notwithstanding the foregoing, the Group shall be entitled to apply
to the Joint Planning Board for the purpose of requesting that a particular
Full-time Physician Employee not be required to execute an employment agreement
that contains the provisions contained in Sections 6.2 and 6.5, which such
release by Administrator shall not be unreasonably withheld.

                                   ARTICLE VII

                       Financial and Security Arrangements

         Section 7.1 Service Fee. The Group and Administrator agree that the
compensation set forth in this Article VII is being paid to Administrator in
consideration of the services provided and the substantial commitment and effort
made by Administrator hereunder and that such fees have been negotiated at arms'
length and are fair, reasonable and consistent with fair market value.
Administrator shall be paid the service fee (the "Service Fee") as set forth on
Exhibit 7.1 hereto. Payment of the Service Fee is not intended to and shall not
be interpreted or implied as permitting Administrator to share in the Group's
fees for medical services but is acknowledged as the negotiated fair market
value compensation to Administrator considering the scope of services and the
business risks assumed by Administrator.

         Section 7.2 Payments. Except as otherwise set forth on Exhibit 7.1
hereto, the amounts to be paid to Administrator under this Article VII shall be
calculated by Administrator on the accrual basis of accounting and shall be
payable monthly. Payments due for any Service Fee shall be made by the Group
each calendar month as provided herein and shall be paid on the 15th day
following the end of such month (or the first preceding day that is a business
day if the 15th day is not a business day) (a "Payment Date"). Except as
otherwise set forth on Exhibit 7.1, such amounts paid shall be estimates based
upon available information for such month, and adjustments to the estimated
payments shall be made to reconcile final amounts due under Section 7.1 on the
next Payment Date.

         Section 7.3 Advances. The Group shall be entitled to an advance from
Administrator of such additional sums, over and above the Group's right to the
amounts otherwise set forth in this Article VII, as shall be required by the
Group to pay Practice Expenses (excluding Technical Expenses) consistent with
the annual capital and operating budgets of the Practice (prepared as provided
in Section 3.5 hereof), the Service Fee as provided in Exhibit 7.1 hereto and
Excluded Practice Expenses at the discretion of Administrator. Any amounts
advanced to the Group pursuant to this Section 7.3 shall be repaid by the Group
in such priority as set forth in Section 7.6 below and shall bear interest at
Parent's then available, borrowing rate offered by Administrator's or Parent's
senior lender (which rate shall be charged consistently 







                                       29
<PAGE>   35

to each physician group who enters into a Service Agreement with Administrator)
until all such amounts of principal and interest are repaid to Administrator as
provided herein. Notwithstanding the foregoing, no interest shall accrue or be
paid by the Group for amounts advanced to the Group pursuant to this Section 7.3
during the forty-five (45)-day period immediately following the Acquisition
Effective Date.

         Section 7.4 Security Agreement. In order to enforce its rights granted
hereunder and subject to applicable law, the Group shall execute a Security
Agreement in substantially the form attached hereto as Exhibit 7.4 (the
"Security Agreement"), which Security Agreement grants a security interest in
all of the Group's accounts receivable (as more fully described in the Security
Agreement) to Administrator. In addition, the Group shall cooperate with
Administrator and execute all necessary documents in connection with the pledge
of such accounts receivable to Administrator or at Administrator's option, its
lenders.

         Section 7.5 Adjustment of Fees. In addition to the adjustments provided
for in Section 7.2, Service Fees payable by Group pursuant to this Article VII
shall be adjusted as appropriate upon agreement of the parties upon the
divestiture or acquisition by the Group of, or affiliation with, a radiology or
diagnostic practice group. Whether or not Parent capital stock or funds are
utilized to fund the acquisition or affiliation, the Service Fee and other
related provisions of this Agreement shall be adjusted as agreed upon by the
parties on a case by case basis. Under either acquisition or affiliation model,
the precise adjustment to the Service Fee and to other related provisions of
this Agreement shall be a joint decision of the parties, shall be memorialized
in a written amendment to this Agreement, and shall be based upon the
methodology used to generally determine Services Fees hereunder.

         Section 7.6 Priority of Payments. Administrator shall administer and
make disbursements from amounts deposited into the Deposit Account or
transferred from the Deposit Account to pay (including, without limitation the
making of advances as provided in Section 7.3) the Practice Expenses and
Excluded Practice Expenses as the same become due and payable, and for which the
Group shall remain responsible; provided, however, that if Technical Expenses
exceed Technical Revenues, then the amount by which Technical Expenses exceed
Technical Revenues shall be excluded for purposes of the priority of payments
set forth below and the Group shall not be responsible for such amount. In
performing its obligations pursuant to Article III, on the fifteenth (15th) day
following the end of each calendar month, Administrator shall apply an amount
equal to the aggregate face amount of the prior month's accounts receivables,
less contractual adjustments and estimated allowances for bad debt as determined
in accordance with Section 3.2(e), in the following order of priority:

         (a)      payment of all accrued Practice Expenses for the prior month
                  (subject to the proviso in the preceding sentence);

         (b)      payment of the accrued Service Fee for the prior month;

         (c)      payment of outstanding balance of all amounts advanced to the
                  Group through the end of the prior month, and applicable
                  interest thereon (as contemplated in Section 7.3); and

         (d)      payment of all Excluded Practice Expenses.

Any amounts which remain following the payment of the items set forth in
subparagraphs (a) through (d) above shall be deposited into the Group Account on
the fifteenth (15th) day following the end of each calendar month (or the first
preceding day if the 15th day is not a business day).

                                  ARTICLE VIII

                                     Records

         Section 8.1 Records. All records relating in any way to the operation
of the Practice (other than Group Records) shall, subject to the obligations of
the Practice to maintain patient medical records pursuant to Section 3.2(g), at
all times be the property of Administrator as set forth in Section 3.2(g).
During the term of this Agreement, and for a reasonable time thereafter, the
Group or its agents shall have reasonable access during normal business hours to
the Group's and Administrator's personnel and financial records relating to the
Practice, including, but not limited to, records of collections, expenses and
disbursements as kept by Administrator in performing Administrator's obligations
under this Agreement, and the Group may copy any or all such records.

                                   ARTICLE IX

                          Insurance and Indemnification

         Section 9.1         Insurance to be Maintained by the Group.

         (a) During the term of this Agreement, the Group shall maintain
comprehensive professional medical/malpractice liability insurance with such
carrier as determined jointly by Administrator and the Group with minimum legal
limits or such higher limits as shall be required under the Group's contracts
with hospitals or other third parties. Such insurance shall be on a per claim
and per physician basis and a separate limit for the Group to the extent
available and permitted by law with such deductible as is mutually agreeable by
Administrator and the Group. All comprehensive professional medical/malpractice
liability insurance premiums and deductibles shall be included in Practice
Expenses; provided, that if the Group elects to maintain coverage that exceeds
minimum requirements, such additional premiums shall be included in Excluded
Practice Expenses. All costs, expenses and liabilities incurred by the Group in
excess of the limits of such policies identified in the preceding sentence shall
be included in Excluded Practice Expenses. Administrator, Parent or their
Affiliates shall attempt to secure excess liability for the types of coverages
contemplated by this Section 9.1(a). If successful, the Group shall have the
opportunity to purchase at Administrator's cost, as an Excluded Practice
Expense, such coverage to the extent permitted by the then-applicable
restrictions set forth in such policy.

         (b) The Group, Administrator and Parent each waives any right one may
have against the other, to the extent allowed by the waiving party's insurance
coverage, on account of any loss or damage occasioned to any party by another
party, their respective real and personal property, the Premises or its
contents, arising from any risk generally covered by fire and extended coverage
insurance or from vandalism or malicious mischief; and the parties, on behalf of
their respective insurance companies, waive any right to subrogation, except
when such loss or damage is due to the gross negligence or willful misconduct of
the other party.

         Section 9.2 Insurance to be Maintained by Administrator. During the
term of this Agreement, Administrator will provide and maintain (i) as a
Technical Expense, comprehensive professional medical/malpractice liability
insurance for all applicable employees of Administrator and (ii) as a Practice
Expense, comprehensive general liability and property insurance covering the
Practice's premises (including, without limitation, the Premises), personal
property and operations with such limits and coverages as a reasonable business
person under similar circumstances would maintain. All costs, expenses and
liabilities incurred by Administrator in excess of the limits of such policies
identified in subsections (i) and (ii) hereof shall be included in Administrator
Expenses.

         Section 9.3 Continuing Liability Insurance Coverage. The Group shall
obtain or require each of its Physician Employees and Physician Extender
Employees to obtain continuing liability insurance coverage under either a "tail
policy" or a "prior acts policy," with the same limits and deductibles as the
insurance coverage provided pursuant to Section 9.1 upon the termination of such
physician's relationship with the Group for any reason, unless such physician
was covered with an occurrence-based policy while employed or retained by the
Group. In the event that the Group, any Physician Employee or Physician Extender
Employees fails to obtain such continuing liability insurance coverage,
Administrator may do so. The cost of such continuing liability insurance
coverage shall be included in Practice Expenses unless such cost is borne by the
Physician Employee.

         Section 9.4 Additional Insureds. The Group and Administrator agree to
use their reasonable efforts to have each other named as an additional insured
on the other's respective professional liability insurance programs. The
additional cost, if any, associated therewith shall be a Practice Expense.

         Section 9.5 Indemnification.

         (a) By the Group. The Group shall indemnify, defend and hold
Administrator, Parent, their Affiliates and their respective officers,
directors, shareholders, employees, agents, attorneys and consultants (other
than such persons who are also officers, directors, shareholders, employees,
agents or consultants of the Group) harmless, from and against any and all
liabilities, losses, damages, claims, causes of action and expenses (including
reasonable attorneys' fees), not covered by insurance (including self-insured
insurance and reserves), whenever arising or incurred, that are caused or
asserted to have been caused, directly or indirectly, by or as a result of the
performance of medical services or the performance of any intentional acts,
negligent acts or omissions by the Group and/or its shareholders, employees
and/or subcontractors (other than Administrator, Parent, Affiliates or their
employees, officers, directors, agents, attorneys and consultants) during the
term of this Agreement. Provided, however, that in the event an indemnification
obligation under the preceding sentence arises as of the result of any act or
omission of a person who is an officer, shareholder or other equity holder,
director, employee, agent, attorney or consultant of Administrator, Parent or
any of their Affiliates (other than in connection with the activities of the
Joint Planning Board), such person shall not be entitled to indemnification in
connection therewith and any other adjustment as is equitable shall be made to
the Group's indemnification obligation arising thereby.

         (b) By the Administrator. Administrator and Parent, jointly and
severally, shall indemnify, defend and hold the Group and its officers,
shareholders, directors, employees, agents, attorneys and consultants, harmless
from and against any and all liabilities, losses, damages, claims, causes of
action and expenses (including reasonable attorneys' fees), not covered by
insurance (including self-insured insurance and reserves), whenever arising or
incurred, that are caused or asserted to have been caused, directly or
indirectly, by or as a result of the performance of any intentional acts,
negligent acts or omissions by Administrator, Parent or Affiliates and/or any of
their respective shareholders, employees and/or subcontractors (other than the
Group or its employees) during the term of this Agreement. Provided, however
that in the event an indemnification obligation under the preceding sentence
arises as a result of any act or omission of a person who is an officer,
shareholder or other equity holder, director, employee, agent, attorney or
consultant of the Group (other than in connection with the activities of the
Joint Planning Board), such person shall not be entitled to indemnification in
connection therewith and any other adjustment as is equitable shall be made to
Administrator's or Parent's indemnification obligation arising thereby.

                                    ARTICLE X

                              Term and Termination

         Section 10.1 Term of Agreement. This Agreement shall commence on the
date hereof and shall expire on the 40th anniversary hereof unless earlier
terminated pursuant to the terms of either Section 10.3 or Section 10.4 or
automatically extended pursuant to the terms of Section 10.2.

         Section 10.2 Extended Term. Unless earlier terminated as provided for
in either Section 10.3 or Section 10.4, the term of this Agreement shall be
automatically extended for additional terms of five (5) years each, unless
either party delivers to the other party, not less than twelve (12) months nor
earlier than fifteen (15) months prior to the expiration of the preceding term,
written notice of such party's intention not to extend the term of this
Agreement.

         Section 10.3 Termination by the Group. The Group may, in its sole
discretion, terminate this Agreement by giving written notice thereof to
Administrator (after the giving of any required notices and the expiration of
any applicable waiting periods set forth below) upon the occurrence of any the
following events:

         (a) Administrator or Parent shall admit in writing its inability to
generally pay its debts when due, apply for or consent to the appointment of a
receiver, trustee or liquidator of all or substantially all of its assets, file
a petition in bankruptcy or make an assignment for the benefit of creditors, or
upon other action taken or suffered by Administrator or Parent, voluntarily or
involuntarily, under any federal or state law for the benefit of creditors,
except for the filing of a petition in involuntary bankruptcy against
Administrator or Parent which is dismissed within ninety (90) days thereafter.

         (b) Administrator or Parent shall default in the performance of any
material duty or material obligation imposed upon it by this Agreement (a
"Material Administrator Default") and such default shall continue for a period
of sixty (60) days after written notice thereof has been given to Administrator
by the Group with a copy to the financial institution contemplated in Section
12.1(a) at the address provided by Administrator, provided that the Group may
terminate this Agreement, if and only if, such termination shall have been
approved by the affirmative vote of the holders of two-thirds of the interests
of the equity holders of the Group. The Group agrees that the financial
institution contemplated in Section 12.1(a) shall have 






                                       33
<PAGE>   39

the right, but not the obligation, to cure any Material Administrator Default.
Notwithstanding anything to the contrary in this Agreement, following receipt by
Administrator of the notice of a Material Administrator Default and until such
Material Administrator Default shall be cured, the Group may take such action as
may be reasonably required to cover such Material Administrator Default so as to
maintain for the Group the same level of service as before the Material
Administrator Default, without prejudicing in any way the Group's other rights
and remedies, and may offset all of its costs from the amounts which may
otherwise be due to Administrator under this Agreement.

         (c) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         Section 10.4 Termination by Administrator. Administrator may, in its
sole discretion, terminate this Agreement by giving written notice thereof to
the Group (after the giving of any required notices and the expiration of any
applicable waiting periods set forth below) upon the occurrence of any of the
following events:

         (a) The Group shall default in the performance of any material duty or
material obligation imposed upon it by this Agreement (a "Material Group
Default") and (i) the Group fails to deliver to Administrator within thirty (30)
days after written notice of such Material Group Default has been given to Group
a written plan (reasonably acceptable to Administrator) detailing the methods
and procedures that the Group shall utilize to cure such Material Group Default,
(ii) the Group has delivered a plan but has failed to utilize its best efforts
to cure such Material Group Default within sixty (60) days after written notice
thereof has been given to the Group by Administrator or (iii) the Group has
delivered the plan but, after utilizing its best efforts, is unable to cure such
Material Group Default within ninety (90) days after written notice thereof has
been given to the Group by Administrator. The term "Material Group Default" for
purposes of this Section 10.4 shall include, but not be limited to, (A) the
Group's admission in writing of its inability to generally pay its debts when
due, application for or consent to the appointment of a receiver, trustee or
liquidator of all or substantially all of its assets, filing of a petition in
bankruptcy or making an assignment for the benefit of creditors, or upon other
action taken or suffered by the Group, voluntarily or involuntarily, under any
federal or state law for the benefit of debtors, except for the filing of a
petition in involuntary bankruptcy against the Group which is dismissed within
ninety (90) days thereafter or (B) the Group or any Physician Employee (1) fails
to adhere to any compliance plan, policy, or manual as described in Section 4.6
hereof that has been approved by the Group and made applicable to all
shareholders and employees of the Group, or (2) engages in any conduct or is
formally accused of conduct for which the Group's ability or license, or a
Physician Employee's license to practice medicine reasonably would be expected
to be subject to revocation or suspension, whether or not actually revoked or
suspended, or (3) is notified in writing of any adverse action by any state or
federal department or agency that has the effect of either excluding that
individual from participating in or from receiving reimbursement under any
program funded by the federal government or by any state government,
notwithstanding any available post-sanction remedies, or (4) is otherwise
disciplined by any licensing, regulatory or professional entity or institution,
the result of any of which event does or is reasonably expected to materially
adversely affect the Practice, the result of any of which event described in
subparagraphs (1) through (4) above, in the absence of termination of a
Physician Employee or a Physician Extender Employee or other action of the Group
to monitor and cure such act or conduct by such employee, does or reasonably
would be expected to materially and adversely affect the Practice or the Group.
Notwithstanding anything to the 






                                       34
<PAGE>   40

contrary in this Agreement, following receipt by the Group of the notice of a
Material Group Default, and until such Material Group Default shall be cured,
the Administrator may take such action as may be reasonably required to cover
such Material Group Default so as to maintain for the Administrator the same
level of service at the Premises as before the Material Group Default, without
prejudicing in any way Administrator other rights and remedies, and may offset
all of its costs of cover from amounts which may otherwise due to the Group
under this Agreement.

         (b) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         (c) At any time during the five-year period following the Acquisition
Effective Date if more than thirty-three and one-third percent (33 1/3%) of the
total number of Group Physician Stockholders and Full-time Physician Employees
retained or employed by the Group at the time of the Acquisition Effective Date
are no longer employed or retained by the Group for reasons other than (i)
death, (ii) permanent disability, (iii) loss of a hospital contract or
privileges for reasons other than voluntary resignation by the Group or a
failure to renew or a failure to respond to a reasonable proposal to extend the
term of such contract or (iv) voluntary closing of facilities by Administrator.
For purposes of this Section 10.4(c), if Parent and/or Administrator are
notified in writing by the Group at or prior to the Acquisition Effective Date
of any Physician Employee that intends to retire prior to expiration of such
five-year period, then such Physician Employee or Physician Extender Employee
shall not be counted for purposes of determining the above percentage.

         Section 10.5 Effective Date of Termination. Any termination of this
Agreement shall be effective (the "Termination Date") as follows:

         (a) Immediately upon receipt of a termination notice pursuant to
Section 10.3 or Section 10.4 (a "Termination Notice") and expiration of
applicable cure periods; or

         (b) Upon the expiration of this Agreement pursuant to Sections 10.1 or
10.2.

         Section 10.6 Purchase of Assets. Upon the termination of this
Agreement, subject to the provisions of subparagraphs (a) through (e) set forth
below, if Administrator is the defaulting party, the Group shall have the option
to require Administrator and/or Parent to sell to the Group, and if the Group is
the defaulting party, Administrator and/or Parent shall have the option to
require the Group to purchase from Administrator, and/or Parent the Purchase
Assets and assume the Practice Related Liabilities below:

         (a) Purchase Assets. The Group shall purchase, free and clear of all
liens and encumbrances other than those arising from Practice Related
Liabilities (as defined below), from Administrator, and/or Parent or its
Affiliates, as the case may be, pursuant to subparagraph (c) below, all assets,
tangible or intangible real or personal, of Administrator, Parent or their
Affiliates that relate primarily to the Practice other than Administrator's,
Parent's or their Affiliates' accounting and financial records (the "Purchase
Assets"), including, but not limited to, without duplication, (i) all equipment,
furniture, fixtures, furnishings, inventory, supplies, improvements, additions
and leasehold improvements utilized by the Practice, (ii) any real estate owned
by Administrator, Parent or Affiliates that is occupied by or used primarily for
the benefit of the Practice, (iii) all unamortized intangible assets (including,
without 





                                       35
<PAGE>   41

limitation, goodwill) set forth on the financial statements of Administrator,
Parent or their Affiliates used in connection with the Practice or otherwise
resulting from the Acquisition, (iv) all Confidential and Proprietary
Information that relates solely to the Practice, and (v) all other assets that
would be set forth on a balance sheet of Administrator, Parent or their
Affiliates prepared as of the date of the Purchase Closing relating primarily to
the Practice.

         (b)      Practice Related Liabilities. The Group shall assume all of
Administrator's and its Affiliates' liabilities, debt, payables and other
obligations (including lease and other contractual obligations), or portions
thereof, which relate directly or are directly attributable to the Practice
and/or the Purchase Assets other than previously accrued Practice Expenses (the
"Practice Related Liabilities").

         (c)      Purchase Price. The Purchase Price shall be the lesser of (i) 
Fair Market Value of the Purchase Assets subject to the assumption of the
Practice Related Liabilities or (ii) the value of the Actual Consideration
(defined below)(alternatively, the "Purchase Price"); provided, however, the
Purchase Price shall not be less than the net book value of the Purchase Assets
at the Termination Date. The Purchase Price shall be paid pursuant to Section
10.7. For purposes of this subparagraph (c), the term "Actual Consideration"
shall mean (i) cash consideration paid to the Group pursuant to the Acquisition
Agreement and (ii) an amount equal to the number of shares of Parent Common
Stock (as adjusted for stock splits, stock dividends, recapitalizations,
reorganizations, or any similar transaction whereby the Parent Common Stock is
increased or decreased or exchanged for a different number or kind of
securities) issued pursuant to the Acquisition Agreement multiplied by the fair
market value of Parent Common Stock immediately prior to the time that a
Termination Notice is provided pursuant to Section 10.7. The Purchase Price
shall be appropriately adjusted to offset and account for any monetary
obligations of the Group or Administrator owing to the other as provided herein.

         (d)      Exercise of Option.

                  (i) The Group. Upon a termination of this Agreement, the Group
shall be entitled to exercise its option to require Administrator, Parent or
their Affiliates to sell the Purchase Assets and shall assume the Practice
Related Liabilities pursuant to this Section 10.6 at any time (unless this
Agreement is terminated pursuant to Section 10.4(a) or 10.4(c)).

                  (ii) Administrator. Upon termination of this Agreement,
Administrator shall be entitled to exercise its option to require the Practice
to purchase the Purchase Assets and assume the Practice Related Liabilities
pursuant to this Section 10.6 (i) during the five-year period following the
Acquisition Effective Date if this Agreement is terminated pursuant to Sections
10.3(c), 10.4(b) or 10.4(c) and (ii) at any time in the event of a termination
pursuant to Section 10.4(a).

         (e)      Notice. Each party shall exercise its option under this 
Section 10.6 by giving written notice thereof in the Termination Notice, if
applicable, or prior to ninety (90) days before the Termination Date if this
Agreement expires pursuant to Sections 10.1 or 10.2.

         Section 10.7 Terms of Purchase. The closing of the transactions
contemplated by Section 10.6 (the "Purchase Closing") shall occur (a) on the
Termination Date if this Agreement expires pursuant to the terms of Sections
10.1 and 10.2, or (b) on a date mutually acceptable to the parties hereto that
shall be within 180 days after receipt of a Termination Notice. The parties
shall enter into an asset purchase agreement containing representations,
warranties and conditions customary to a transaction of this size involving the
purchase and sale of similar businesses. Subject to the conditions set forth
below, at





                                       36
<PAGE>   42

the Purchase Closing, Administrator and/or its Affiliates, as the case may be,
shall transfer and assign the Purchase Assets to the Group, and in consideration
therefor, the Group shall (a) pay to Administrator, Parent and/or their
Affiliates an amount in cash or, at the option of the Group (subject to the
conditions set forth below), Parent Common Stock (valued at the fair market
value immediately prior to the Purchase Closing), or some combination of cash
and Parent Common Stock equal to the Purchase Price and (b) assume the Practice
Related Liabilities. Each party shall execute such documents or instruments as
are reasonably necessary, in the opinion of each party and its counsel, to
effect the foregoing transaction. The Group shall, and shall use its best
efforts to cause each shareholder of the Group to, execute such documents or
instruments as may be necessary to cause the Group to assume the Practice
Related Liabilities and to release Administrator, Parent and/or their
Affiliates, as the case may be, from any liability or obligation with respect
thereto. In the event the Group desires to pay all or a portion of the Purchase
Price in shares of Parent Common Stock, such transaction shall be subject to the
satisfaction of each of the following conditions:

         (a) The holders of such shares of Parent Common Stock shall transfer to
Administrator, Parent and/or their Affiliates good, valid and marketable title
to the shares of Parent Common Stock, free and clear of all adverse claims,
security interests, liens, claims, proxies, options, stockholders' agreements
and encumbrances (not including any applicable securities restrictions and
lock-up arrangements with the Parent or any underwriter); and

         (b) The holders of such shares of Parent Common Stock shall make such
representations and warranties as to title to the stock, absences of security
interests, liens, claims, proxies, options, stockholders' agreements and other
encumbrances and other matters as reasonably requested by Administrator, Parent
and/or their Affiliates.

         Section 10.8 Exception to Purchase. Notwithstanding anything contained
herein to the contrary, Administrator, Parent and/or their Affiliates shall not
be obligated to sell the Purchase Assets to the Group as provided in Section
10.6(d)(i) above if the Group is not able to pay the Purchase Price pursuant to
the terms set forth above and assume the Practice Related Liabilities at the
Purchase Closing. In such event, the Group shall surrender the Purchase Assets
to Administrator, Parent and/or their Affiliates as of the Purchase Closing. If
the Practice fails to so surrender the Purchase Assets, Administrator, Parent
and/or their Affiliates may, if permitted by applicable law, without prejudice
to any other remedy which it may have hereunder or otherwise, enter the Premises
and take possession of the Purchase Assets and expel or remove the Group and any
other person who may be occupying the Premises or any part thereof, by force if
necessary, without being liable for prosecution or any claim for damages
therefor.

         Section 10.9 Effect Upon Termination. Upon the Termination Date, except
as provided below, this Agreement shall terminate and shall be of no further
force and effect and all further obligations of Administrator, Parent and/or
their Affiliates and the Group under this Agreement shall terminate without
further liability of the Administrator or Parent and/or their Affiliates to the
Group or the Group to the Administrator or Parent and/or their Affiliates
(including, without limitation, any liability for loss of anticipated profits
over the remaining term of this Agreement or from a sale of the Purchase Assets
pursuant to this Article X at less than Fair Market Value), except with respect
to the obligations set forth below. The foregoing to the contrary
notwithstanding:

         (a) Administrator and Parent and/or their Affiliates shall use their
best efforts to cooperate with the Group for the appropriate transfer of
management services.



                                       37
<PAGE>   43


         (b) Each party hereto shall provide the other party with reasonable
access to books and records owned by it to permit such requesting party to
satisfy reporting and contractual obligations which may be required of it.

         (c) Any other amounts due and owing but unpaid to either Administrator,
Parent and/or their Affiliates or the Group as of the Termination Date shall be
paid promptly by the appropriate party.

         (d) Any and all covenants and obligations of either party hereto which
by their terms or by reasonable implication are to be performed, in whole or in
part, after the termination of this Agreement, shall survive such termination,
including, without limitation, the obligations of the parties pursuant to the
following Sections: 6.1(b), 6.1(c), 6.1(d), 6.1(e), 6.2, 6.3, 9.5, Article VIII
and the applicable provisions of Article X and XI.

                                   ARTICLE XI

                               Dispute Resolution

         Section 11.1 Informal Dispute Resolution. In the event of any claim,
controversy, dispute or disagreement between or among the parties hereto which
is not subject to the dispute resolution methodology set forth in Article V
hereof, the parties hereto agree that such other claims, controversies, disputes
or disagreements shall be presented to the Joint Planning Board for hearing and
resolution. In the event the Joint Planning Board is unable to resolve such
matter within a reasonable period following presentation to the Joint Planning
Board, such matter shall be presented to either (a) the Board of Directors of
Parent or (b) a committee designated by the Board of Directors of Parent which
contains at least one (1) physician member. The Board of Directors of Parent or
such committee shall meet within thirty (30) days to attempt to resolve such
claim, controversy, dispute or disagreement.

                                   ARTICLE XII

                               General Provisions

         Section 12.1 Assignment. Administrator shall have the right to assign
its rights hereunder to Parent or any direct or indirect wholly-owned subsidiary
of Administrator or Parent (that remains a wholly-owned subsidiary of
Administrator or Parent) or to a financial institution as collateral security
for the indebtedness of Parent, Administrator or their Affiliates without the
consent of the Group.

         Section 12.2 Amendments. This Agreement shall not be modified or
amended except by a written document executed by all parties to this Agreement,
and such written modification(s) or amendment(s) shall be attached hereto.

         Section 12.3 Waiver of Provisions. Any waiver of any 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.

         Section 12.5 Attorneys' Fees. If legal action is commenced by either
party to enforce or defend its rights under this Agreement, the prevailing party
in such action shall be entitled to recover all reasonable attorneys' fees,

other relief granted.

         Section 12.6 Contract Modifications for Prospective Legal Events. In
the event any state or federal laws or regulations, now existing or enacted or
promulgated after the date hereof, are interpreted by judicial decision, a
regulatory agency or independent legal counsel in such a manner as to indicate
that this Agreement or any provision hereof may be in violation of such laws or
regulations, the Group and Administrator shall amend this Agreement as necessary
to preserve the underlying economic and financial arrangements between the Group
and Administrator and without substantial economic detriment to either party. If
this Agreement cannot be so amended, the terms of Section 10.3(c) and 10.4(b)
shall apply. To the extent any act or service required of Administrator in this
Agreement should be construed or deemed, by any governmental authority, agency
or court to constitute the practice of medicine, the performance of said act or
service by Administrator shall be deemed waived and forever unenforceable and
the provisions of this Section 12.6 shall be applicable. Neither party shall
claim or assert illegality as a defense to the enforcement of this Agreement or
any provision hereof; instead, any such purported illegality shall be resolved
pursuant to the terms of this Section 12.6 and Section 12.9.

         Section 12.7 Parties In Interest; No Third Party Beneficiaries. Except
as otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and permitted assigns of the parties hereto. Except
as provided in Section 6.1(g), neither this Agreement nor any other agreement
contemplated hereby shall be deemed to confer upon any person not a party hereto
or thereto any rights or remedies hereunder or thereunder.

         Section 12.8 Entire Agreement. This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,
both written and oral, among the parties, or any of them, with respect to the
subject matter hereof.

         Section 12.9 Severability. If any provision of this Agreement is held
to be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
herefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 12.10 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULE GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF FLORIDA.

         Section 12.11 No Waiver; Remedies Cumulative. No party hereto shall by
any act (except by written instrument pursuant to Section 12.3 hereof), delay,
indulgence, omission or otherwise be deemed to 





                                       39
<PAGE>   45

have waived any right or remedy hereunder or to have acquiesced in any default
in or breach of any of the terms and conditions hereof. No failure to exercise,
nor any delay in exercising, on the part of any party hereto,. any right, power
or privilege hereunder shall operate as a waiver thereof. No single or partial
exercise of any right, power or privilege hereunder shall preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
No remedy set forth in this Agreement or otherwise conferred upon or reserved to
any party shall be considered exclusive of any other remedy available to any
party, but the same shall be distinct, separate and cumulative and may be
