       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
Group shall retain the exclusive authority to direct the medical, professional,
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 payment or compensation in cash or in kind for, and are not in any way
contingent upon the admission, referral or any other arrangement for the
provision of any item or service offered by Administrator or any of its
Affiliates to any of the Group's patients in any facility controlled, managed

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

in Administrator's provision of services hereunder.

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

Administrator for the term of this Agreement to be its true and lawful
attorney-in-fact, for the following purposes:





                                       9
<PAGE>   15
                     (A)    to bill patients, insurance companies, Managed Care
Payors, and other third-party payors in the Group's name and on its behalf;

                     (B)    to collect accounts receivable resulting from such

3.2(e) hereof) in the Group's name and on its behalf;

                     (C)    to receive payments on behalf of the Group from

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

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 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

request of Administrator shall provide reasonable assistance to, Administrator

the Joint Planning Board in the preparation of all annual capital and operating
budgets.  These annual budgets shall be subject to the review, amendment and
approval or disapproval of the Board of Directors of Parent or a committee
designated by such Board of Directors.  For purposes of developing the initial
annual operating budget, the Joint Planning Board shall take into account the
categories of expenses determined by Administrator and Joint Planning Board.
The projected annual operating budget for each subsequent year shall be subject
to the approval of the Joint Planning Board and shall reflect the Group's
anticipated staffing requirements for the next fiscal year, as well as other
anticipated expenses of the Practice.  For purposes of developing the annual
capital budget, the Joint Planning Board will include budgeted amounts for any
anticipated expansion of existing facilities, acquisition of new facilities,
acquisition or upgrades of equipment, any practice asset acquisitions, and any
other anticipated capital expenses of the Practice.

       (b)    Capital Expenditures.  Subject to the terms contained herein,
Administrator will make funds available for capital expenditures and
improvements by Administrator on behalf of the Practice as follows:

              (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 and approval shall be based on confirming that the assumption, facts and
circumstances on which the decision to budget for such expenditure was based
still support and justify the actual expenditures.

              (ii)   Non-Budgeted Expenditures.  Requests for non-budgeted
capital expenditures and improvement projects shall be evaluated and prepared
by the Joint Planning Board in consultation with the Group and Administrator.
All requests for non-budgeted capital expenditures and improvements at or for
the benefit of the Practice in excess of either $50,000 individually or an
aggregate amount equivalent to $2,500 multiplied by the number of Full-time
Physician 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.

<PAGE>   21
       (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   Provider and Payor Relationships.  Administrator shall
provide financial and business assistance to the Group in the negotiation,
establishment, supervision and maintenance of contracts and relationships
(collectively, the "Managed Care Contracts") with all managed care,
institutional health care providers and payors, health maintenance
organizations, preferred provider organizations, exclusive provider
organizations, Medicare, Medicaid, insurance companies, hospitals and other
similar persons (collectively, "Managed Care Payors").  Approval, disapproval,
termination or amendment of any contract or relationship of such Managed Care
Payors with the Group shall, after consultation with the Joint Planning Board,
be the responsibility of the Group.  [Notwithstanding the preceding language,
if a contract or relationship between any Managed Care Payor and the Group
involves or affects a contract or relationship with any other physician group
or practice serviced or managed by Administrator, Parent or any of their
Affiliates (the "Other Practices") and a consensus among the Group and the
Other Practices cannot be reached regarding the contract or relationship, then
the ultimate decision as to the approval, disapproval, termination or amendment
of such contract or relationship involving the Group, the Other Practices and
such Managed Care Payor shall be determined by the affirmative vote of the
Physician Board Members (as defined below) who hold a majority of the Group
Voting Power (as defined below).  For purposes of this Section 3.7, (i) the
term "Physician Board Members" shall mean (a) those members appointed by the
Group who serve on the Joint Planning Board and (b) those persons appointed by
the Other Practices who serve on the Other Practices' joint boards (in a
similar capacity to the Joint Planning Board) as





                                       16
<PAGE>   22
part of their contractual relationship with Parent, Administrator or any of
their Affiliates, and (ii) the term "Group Voting Power" shall mean the total
voting percentage which may be cast by the Physician Board Members on a
collective basis, with the percentage of votes able to be cast by any Group or
Other Practice, as applicable, shall be equal to the quotient determined by
dividing (x) the total estimated annual professional revenues to be generated
by the Group from such Managed Care Contract as determined by Administrator,
Parent or their Affiliates, as appropriate, in its sole discretion, by (y) the
total estimated annual professional revenues to be generated by the Group and
all Other Practices from such Managed Care Contract as determined by the
Administrator, Parent or their Affiliates, as appropriate, in its sole
discretion.]

       Section 3.8   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 3.9   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 3.10  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 3.11  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 3.12  Events Excusing Performance.  In the event of strikes,
lock-outs, calamities, acts of God, unavailability of supplies or other events
over which Administrator has





                                       17
<PAGE>   23
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.

<PAGE>   24
       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 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





                                       19

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 best
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

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;

any event affecting the initial or continued right to any benefit or payment on

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

       Section 4.8   Premises and Personal Property.   The Group shall use its
[reasonable] efforts to prevent damage, excessive wear and tear, and

both orally and in writing 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 aware.  The Group shall comply with all covenants

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

                                   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





                                       21
<PAGE>   27
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 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.





                                       22
<PAGE>   28
       (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 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.

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

                             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 APPI Group anywhere within 15
miles of any location at which any member of the APPI 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 APPI 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 APPI Group; (iii) directly
or indirectly solicit, or induce any party to solicit, any contractors of any
member of the APPI 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
business of any member of the APPI Group.

       (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.

       (f)    Third Party Beneficiaries.  The members of the APPI Group not

       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 APPI
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,





                                       28
<PAGE>   34
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 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





                                       29
<PAGE>   35
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 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   Survival of Certain Covenants.  If this Agreement is
terminated pursuant to 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





                                       30
<PAGE>   36
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 6.7   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





                                       31
<PAGE>   37
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 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;





                                       32
<PAGE>   38
       (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.

<PAGE>   39
                                   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





                                       34
<PAGE>   40
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.

                              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 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 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





                                       37
<PAGE>   43
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 [or Physician Extender 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,





                                       38
<PAGE>   44
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
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).





                                       39
<PAGE>   45
       (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 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.

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.

       (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.

                               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.

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

any 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

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.
