capital and operating budgets reflecting in reasonable detail anticipated
revenues and expenses and sources and uses of capital for the development and

                  (a)      IPA hereby appoints Manager as its sole and exclusive
manager and administrator of all day-to-day business functions for IPA's risk
contract business. IPA agrees that the purpose and intent of this Agreement is
to relieve its Participating Physicians and other Providers, to the maximum
extent possible, of the administrative, accounting, personnel and business
aspects of IPA, with Manager assuming responsibility and being given all
necessary authority to perform these functions. Manager's specific
responsibilities shall include without limitation: (i) maintaining open

agree that IPA, through its governing body and Participating Physicians and
Providers, and not Manager, shall be responsible and liable for and shall have
complete authority, supervision, and control over the provision of all Medical
Services performed for patients and that all diagnoses, treatments and
procedures related to Medical Services shall be provided and performed under the
supervision of Physicians or other appropriately licensed professionals, as such
professionals, in their sole discretion, deem appropriate.

following purposes: (i) to bill managed care organizations in IPA's name and on
its behalf; (ii) to collect accounts receivable resulting from such billing in
IPA's name and on its behalf; (iii) to receive payments from Payors, including

checks, money orders, insurance payments and other instruments received in
payment of accounts receivable; (v) to determine, based on criteria set by IPA,
which claims for payment from Participating Physicians are appropriate and to
pay such claims on a prompt basis, including fee for service and capitation
payments due Participating Physicians pursuant to the Participation Agreement
and to make prompt payment within thirty days of properly submitted "clean"
claims presented for payment by any other providers who are to be paid by IPA,
and (vi) with IPA's prior written consent, to initiate the institution of legal
proceedings in the name of IPA to collect any accounts and monies owed to the
IPA, to enforce the rights of IPA as creditors under any contract or in
connection with the rendering of any Covered Service, and to contest adjustments
and denials by governmental agencies (or their fiscal intermediaries). Manager

mutually agreed to by Manager and IPA.

of attorney and appoints Manager as IPA's true and lawful agent and attorney-in
fact, and Manager hereby accepts such special power of attorney and appointment,
to deposit appropriate funds into the IPA account and to make withdrawals in
accordance with the banking resolution from the IPA account for payments
specified in this Agreement and as requested by IPA. Manager shall be obligated
to deposit any monies or other assets it receives for any reason on behalf of
IPA in the IPA account. Notwithstanding the special power of attorney granted to
Manager hereunder, IPA may continue to draw checks on the IPA account. Upon
request of Manager or the financial institution wherein the IPA account is
maintained, such additional documents or instruments as may be necessary to
evidence or effect the special power of attorney shall be granted to Manager by
IPA.

                  (d)      Manager shall design, supervise and maintain custody

remain the property of IPA or its Participating Physicians or Providers and
shall be located at clinical facilities where they are readily accessible for
patient care. The management of all medical records shall comply with applicable
state and federal statutes. Manager shall use its best efforts to preserve the
confidentiality of patient medical records and use information contained in such
records only for the limited purposes necessary for performing the services set

confidentiality requirement be deemed a default under this Agreement.

                  (e)      Manager shall provide the data necessary for IPA to
prepare its annual income tax returns and shall assist IPA in the preparation
and filing of such returns. Manager, however, shall have no responsibility for

to credentialing standards of IPA or the Payors), arranging interviews and
reporting the results of the credentialing of each physician to the appropriate

with credentialing and recredentialing standards of any physician to become
associated with IPA, and IPA shall be responsible for implementing the
appropriate credentialing standards and offering or denying a Participation
Agreement to a physician.

manner as to ensure timely and accurate processing and payment of claims
consistent with IPA's Participation Agreements and Payor Contracts. Manager
shall advise and consult with IPA regarding the fees for Covered Services;
however, physician members of the IPA Board shall establish the fees to be
charged for Covered Services, and Manager shall have no authority whatsoever
with respect to the establishment of such fees. If contracts are negotiated by
Manager with a Payor which involve a pass through of physician fees with little
or no integration of activities or which put physicians at little risk for the
performance of other physicians, then Manager shall comply with all requirements
established from time to time by applicable federal or state antitrust
enforcement authorities

reviewing each referral, based upon established medical criteria, to ensure that
the referral is appropriate under the applicable requirements regarding medical
necessity and utilization. Manager shall assist IPA in assuring that referral
authorizations are processed, routed to the appropriate specialty care provider,
or denied.

         3.12     NEW SERVICES. Manager shall work with IPA to consider from
time to time whether it would be in the best interests of IPA for Manager to
make additional services available to IPA at its expense. If the parties
mutually agree on a new service, Manager shall make a good faith effort to
develop or acquire such services for IPA. Manager and IPA will together
establish fees for such services, taking into account the costs involved in
providing them.

         3.13     COMPLIANCE WITH APPLICABLE LAWS. Manager shall comply with

professional liability insurance coverage is through a claims made policy shall
either purchase tail coverage for such period or else remain in the practice of

than those set forth above.

                  (b)      IPA Insurance. IPA shall purchase managed healthcare

         6.2      RECORDS. IPA shall maintain records and procedures as may be
required to account accurately for all Covered Services and other Medical
Services provided pursuant to this Agreement. Such records shall be kept in
accordance with generally accepted accounting principles, consistently applied,
and recognized standards of professional practice.

         6.3      INDEMNIFICATION.

                  (a)      IPA Indemnification. IPA shall indemnify, hold

cause of action, cost or expense, including reasonable attorneys' fees, caused
or asserted to have been caused, directly or indirectly, by or as a result of

                                  ARTICLE VII
                            COMPENSATION TO MANAGER

such costs and expenses can vary to a considerable degree. Furthermore, IPA and
Manager agree that it will be impracticable to ascertain and segregate the exact
costs and expenses that will be incurred by Manager from time to time in

provided, however, the fee increase shall not exceed 3% in any one year.

                  (b)      Incentive Fee. From time to time the IPA is expected
to accumulate an IPA Surplus. When Manager and IPA mutually determine, on a
quarterly basis, that sufficient funds are available to met IPA contingencies,
including an amount for reasonable reserves, and cash flow needs, Manager may
make available to IPA for distribution, fifty percent (50%) of such IPA Surplus
and may distribute fifty percent (50%) to itself as the incentive component of
its management service fee.

cost of the items identified as IPA Expenses, and Manager shall have no
liability therefor.

         2.1      RETENTION OF MANAGER. QCN, Ltd. hereby retains Manager for the
purpose of rendering all Managerial Services as specified in Article III hereof
(which shall not include any third party administrative services performed with
regard to any contract with a preferred provider organization), and Manager
accepts such retention, subject at all times to the provisions of this
Agreement.

         2.2      ENGAGEMENT TERMS. QCN, Ltd. retains Manager as its sole and
exclusive provider of Managerial Services. Subject to Section 8.2 hereof,
Manager agrees that Manager will provide all services described in this
Agreement exclusively to QCN, Ltd., and that Manager will not provide such
services to any other organizations in the Exclusive Area. Manager shall provide
such Managerial Services to QCN, Ltd. as QCN, Ltd. may reasonably request.
Manager is expressly authorized to provide such Managerial Services in any
reasonable manner Manager deems appropriate to meet the day-to-day requirements
of the business needs of QCN, Ltd. and the QCN Network, unless instructed
otherwise by QCN, Ltd. Manager shall perform the Managerial Services at
locations provided by Manager. Manager shall comply with all applicable federal,
state, and local laws, regulations and restrictions in the conduct of its
obligations under this Agreement.

         2.3      NEW SERVICES. Manager, at its option, shall have the first
right to provide additional or new business management and other services
necessary to support QCN, Ltd. if QCN, Ltd. deems such additional or new
services necessary. Should Manager decline to provide the new or additional
services, QCN, Ltd. may perform or purchase such services from others at its
own expense. The parties agree that for Payor Contracts which provide for the
payment of compensation amounts to Participating Physicians which are determined
by fee schedules in the Payor Contracts rather than capitation, NAMM shall be
authorized to negotiate for access fees to be paid to QCN, Ltd. (or for marginal
markups to the physician fee schedule amounts to be retained by QCN, Ltd.) to
compensate QCN, Ltd. for implementing the Payor Contracts and for its activities
in processing and repricing physician claims submitted to the Payor.

and shall provide each other the opportunity to be present at and participate
in all meetings of either QCN, Ltd. or Manager with any Payor or potential or
prospective Payor.

         3.1     PERFORMANCE OF MANAGEMENT FUNCTIONS. Manager may provide or
arrange for others to provide the Managerial Services called for by this
Agreement; provided, however, before any party other than Manager may provide
such services, QCN, Ltd. must have approved the provision of such services by

accordance with those general standards and instructions of QCN, Ltd. which
have been provided to Manager in writing. Manager covenants and agrees that,
at all times during the performance of its Managerial Services, it will adhere

year of QCN, Ltd. Manager and QCN, Ltd. agree to make decisions regarding
capitation rates, Manager's administrative budget, and other financial terms
consistent with prudent business practices and in the best interests of the
QCN Network. The parties acknowledge that the budget may need to be amended
from time to time to reflect variances reasonably explained by volume
fluctuations.

regarding the provision of its Managerial Services and shall prepare and
maintain financial books and records reflecting the administration of the Payor
Contracts, including any amounts retained in or distributed out of any Pools on

reasonable notice and at QCN, Ltd.'s cost; provided, however, if such audit
reveals that Manager has overstated its reimbursable costs to QCN, Ltd. by five
percent (5%) or more, the cost of such audit shall be borne by Manager, and the
expense of such audit shall not be reimbursable under Section 6.2 hereof.

         3.4      ACCESS. Upon reasonable notice to Manager, and without

                              TERM AND TERMINATION

         7.1      TERM AND RENEWAL OPTIONS. The initial term of this Agreement
shall commence on the date first set forth above and shall expire on the seventh
(7th) anniversary of that date, unless extended or earlier terminated pursuant
to the terms hereof. This Agreement shall automatically renew for two (2)
additional seven (7) year terms, unless either party (the "Non-Renewing Party")
provides written notice to the other at least one hundred eighty (180) days
prior to the expiration of the then current term that such other party is
currently failing to meet a Material Condition to Renewal (as hereinafter
defined), and that the Non-Renewing Party does not, as a consequence, elect to
renew the Agreement when the current term ends.

                  (a)      Material Conditions for Renewal - QCN, Ltd. Option.
Upon the occurrence of one or more of the following failures to meet expected
conditions, QCN, Ltd. may elect not to renew this Agreement for an additional
term:

                           (1)      The QCN Network has failed to generate a
surplus for two of the last three fiscal years prior to the end of the term. The
determination of whether the QCN Network will generate a surplus in the final
fiscal year of the term will be based upon projections for the QCN Network for
that year that incorporate reasonable estimates and assumptions.

                           (2)      The QCN Network enrollment during the prior
fiscal year has averaged less than 40,000 commercial equivalent lives (one
Medicare life is equal to three commercial equivalent lives and one commercial
life is equal to one commercial equivalent life).

                  (b)      Material Conditions for Renewal - Manager Option.
Upon the occurrence of one or more of the following failures to meet expected
conditions, Manager may elect not to renew this Agreement for an additional
term:

                           (1)      The QCN Network has failed to generate a
surplus for two of the last three fiscal years prior to the end of the term. The
determination of whether the QCN Network will generate a surplus in the final
fiscal year of the term will be, based upon

                                       9
<PAGE>   10

projections for the QCN Network for that year that incorporate reasonable
estimates and assumptions.

                           (2)      The QCN Network enrollment during the prior
fiscal year has averaged less than 40,000 commercial equivalent lives.

         7.2      Termination.  This Agreement may be terminated, other
provisions notwithstanding, under any of the following circumstances:

                  (a)      Termination by Agreement.  In the event QCN, Ltd. and
Manager shall mutually agree to terminate in writing.

                  (b)      Termination on Notice for Default.  This Agreement
may be terminated by either party in the event that the other party shall be in
default in the performance of any material covenant, duty or obligation under
this Agreement, and such default shall not have been cured within sixty (60)
days following written notice to the other party. The non-defaulting party shall
have the right to terminate this Agreement; provided, however, if during the
sixty (60) day cure period the defaulting party has made and is continuing to
make a good faith effort to cure such default, but the process of cure requires
additional time, and the granting of such additional time does not materially
damage or materially prejudice any rights of QCN, Ltd. or Manager, this
Agreement shall not terminate so long as the defaulting party is making a good
faith effort to cure such default, and so long as such continuing default does
not materially damage or materially prejudice any rights of QCN, Ltd. or
Manager.

                  (c)      Termination for Specific Events.  This Agreement may
be terminated by either party in the event of the dissolution of the other party
or upon the other party's failure to remain viable as a legal entity.

                  (d)      Bankruptcy or Insolvency.  By either party in the
event the other party shall apply for or consent to the appointment of a
receiver, trustee or liquidator of all or a substantial part of its assets, file
a voluntary petition in bankruptcy, admit in writing its inability to pay its
debts regularly as they become due, make a general assignment for the benefit of
creditors, file a petition or an answer seeking reorganization or arrangement
with creditors or to take advantage of any insolvency law, or in the event an
order, judgment or decree shall be entered by a court of competent jurisdiction
adjudicating such party a bankrupt or insolvent, or approving a petition seeking
reorganization of a party, or appointment of a receiver, trustee or liquidator
of all or a substantial part of its assets.

                  (e)      Material Corporate Malfeasance.  By either party in
the event the other party is convicted of a felony as an entity or commits an
act of corporate malfeasance which, in the reasonable opinion of the other
party, would have a high likelihood of injuring the reputation of the other
party or its members or affiliates.

<PAGE>   11

                  (f)      Termination Due to Legislative or Administrative
Changes. As set forth below, in the event that there shall be a change in
Medicare or Medicaid statutes, regulations, or instruction (or in the
application thereof), the adoption of new legislation, judicial interpretations,
or a change in any other third party payor reimbursement system, or any similar
matter which materially and adversely affects either party's rights or
obligations, then the parties shall cooperate to take such actions as may be
necessary to either reform the transaction such that the parties feel
comfortable with it or to the extent necessary to assure the closest possible
compliance with statutory, regulatory and common law demands. Nothing in this
Agreement shall be interpreted to require either party at any time to do
anything that is illegal or contrary to statute.

         7.3      EFFECT OF TERMINATION. Upon termination of this Agreement,
neither party shall have any further obligations hereunder, except for (i)
obligations accruing prior to the effective date of termination, and (ii)
obligations, promises or covenants set forth herein that are expressly made to
survive termination of this Agreement.

Providers may desire to interface with Manager's computer system or access data
via modem, and Manager agrees to accommodate the Participating Providers to the
extent it does not impose an undue financial or operational burden on Manager.

                  (b)      Ownership of Systems. The parties acknowledge that
MHS is the owner of a license (the "License") to use the EZ Cap software program

licensor of the Software to consent to the transfer of the License from MHS to
QCN, Ltd. If the License to use the Software is transferred to QCN, Ltd., such
License shall remain the exclusive property of QCN, Ltd. or its assigns;
provided, however, that Manager shall have access to data files created by and
stored within the Software for the purposes of performing the Managerial
Services. If it becomes necessary to expand the scope of the License as a result
of an increase in the number of Participating Providers in the QCN Network, QCN,
Ltd. shall be responsible for taking all actions necessary or required to expand
the scope of the License at its own expense. The parties further acknowledge

Software") to customize the functions of the Software to meet the Manager's
specifications. QCN, Ltd. hereby acknowledges that the Ancillary Software and

or to such other address of which either party shall notify the other in
writing.

         8.6      BINDING ON SUCCESSORS. This Agreement shall be binding upon
the parties hereto and their respective successors and assigns, if any. It is
not the intention of QCN, Ltd. or Manager that Payors or Enrollees shall be
third party beneficiaries of the obligations of either party to this Agreement,
and no such Payors and Enrollees shall have the right to enforce any such
obligations.

         8.7      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 subsequent breach of the same or any other terms and conditions hereof.

         8.8      GOVERNING LAW. The validity, interpretation and performance of
this Agreement shall be governed by and construed in accordance with the laws of
the State of Texas. The parties acknowledge that neither Manager nor QCN, Ltd.
is authorized or qualified to engage in any activity which may be construed or
deemed to constitute the practice of medicine or be in the business of
insurance. To the extent any act or service required of Manager in this
Agreement, or any obligation of QCN, Ltd., should be construed or deemed, by any
governmental authority, agency or court to constitute the practice of medicine
or be in the business of insurance, the performance of said act or service by
Manager or QCN, Ltd., as applicable, shall be deemed waived and forever
unenforceable.

         8.9      SEVERABILITY. The provisions of this Agreement shall be deemed
severable, and if any portion shall be held invalid, illegal or unenforceable
for any reason, the remainder of this Agreement shall be effective and binding
upon the parties provided that the substance of the economic relationship
created by this Agreement remains materially unchanged.

         8.17     EVENTS EXCUSING PERFORMANCE. Manager and QCN, Ltd. shall not
be liable to the other party for failure to perform any of the services required
herein in the event of strikes, lock-outs, calamities, acts of God, or other
events over which the respective party has no control for so long as such events
continue and for a reasonable period of time thereafter.

         8.18     DISPUTE RESOLUTION. Should a dispute arise out of this
contact, the parties to the dispute shall first attempt to resolve it through
direct discussions in the spirit of mutual cooperation. If the parties' attempts
to resolve their disagreements through negotiation fail, the dispute shall be
mediated by a mutually acceptable third party to be chosen by the disputing
parties within thirty (30) days after written notice by one of them demanding
mediation. The disputing parties shall share the costs of the mediation equally.
By mutual agreement the parties may postpone mediation until each has completed
some specified but limited discovery about the dispute. By mutual agreement the
parties may use a nonbinding form of dispute resolution other than mediation.
Any nonbinding dispute resolution process conducted under the term of this
section shall be confidential as required by the Tex. Civ. Prac. and Rem. Code
Sec. 154.053 and 154.073. In the event that a negotiated or mediated resolution
is not obtained within the time periods provided by this section, the parties
may pursue any available legal or equitable remedy.

         IN WITNESS WHEREOF, this Agreement is entered into and executed as of
the date first written above.
