of action, and expenses, including, without limitation, reasonable attorney's
fees and associated costs, associated with or directly or indirectly resulting
from any act or omission of Medical Practice, its employees, agents, or
independent contractors during the Term.  To be entitled to such
indemnification, the Manager shall give Medical Practice prompt written notice
of the assertion by a third party of any claim with respect to which the Manager
might bring a claim for indemnification hereunder, and in all events must
provide written notice to Medical Practice within the applicable period for
defense of such claim by Medical Practice.  Medical Practice shall, as a Medical
Practice Expense, have the right to defend and litigate any such third-party
claim.

          4.8 CONFIDENTIAL AND PROPRIETARY INFORMATION.  Medical Practice
acknowledges the confidentiality of its relationship with the Manager and of any
Confidential Information of which it may learn or obtain during the Term of this
Agreement.  Medical Practice shall not, either during the Term of this Agreement
or at any time after the expiration or sooner termination of this Agreement,
directly or indirectly, disclose to any person or entity other than employees,
agents or independent contractors engaged by Medical Practice, any Confidential
Information obtained or learned by Medical Practice.  Medical Practice also
agrees to place any person, including all Physicians, to whom confidential
information is disclosed for the purpose of performance under legal obligation
to treat Confidential Information as strictly confidential.

          4.9 NONCOMPETITION. Medical Practice recognizes and acknowledges that
the Manager will incur substantial costs in providing the equipment, support
services, personnel, marketing, management, administration, and other items and
services that are the subject matter of this Agreement, and that in the process
of providing services under this Agreement, Medical Practice will be privy to
financial and confidential information, to which Medical Practice would not
other wise be exposed. The parties also recognize that the services to be
provided by the Manager will

                                       14
<PAGE>
 
be feasible only if Medical Practice operates an active practice to which the
Physicians associated with Medical Practice devote their full time and
attention.

              4.9-1 Medical Practice agrees that ** CONFIDENTIAL INFORMATION **,
neither it nor any of its partners shall establish, operate, or provide
physician services at a medical office, clinic, or other health-care facility
providing services substantially similar to the services provided by Medical
Practice hereunder anywhere within
     ** CONFIDENTIAL INFORMATION **.

              4.9-2 Except as specifically agreed to by the Manager in writing,
Medical Practice covenants and agrees that during the Term, Medical Practice
shall not directly or indirectly own, manage, operate, control, or be otherwise
associated with, lend funds to, lend its name to, or maintain any interest
whatsoever in any enterprise (i) having to do with the provision, distribution,
marketing, promotion, or advertising of any type of management or administrative
services or products in competition with the Manager in Harris County, Texas;
and/or (ii) offering any type of service(s) or product(s) similar to those
offered by the Manager in Harris County, Texas.

              4.9-3 Medical Practice shall obtain and enforce formal agreements
from its partners, their shareholders, and physician employees pursuant to which
the partners, their shareholders and employees agree not to own, establish,
operate, manage, or provide physician services at any medical office, clinic, or
facility providing services similar to those provided by Medical Practice
hereunder within ** CONFIDENTIAL INFORMATION **. Medical Practice may provide
in such restrictive covenants that the former partner, shareholder, or employee
may be released from the restrictive covenant by paying liquidated damages.

              4.9-4 Medical Practice understands and acknowledges that the
foregoing provisions in Section 4.8 and Section 4.9 are designed to preserve the
goodwill of the Manager and the goodwill of the individual Physicians of Medical
Practice.  Accordingly, if Medical Practice breaches any obligation of Section
4.8 or Section 4.9, in addition to any other remedies available under this
Agreement, at law or in equity, the Manager shall be entitled to enforce this
Agreement by injunctive relief and by specific performance of the Agreement,
such relief to be without the necessity of posting a bond, cash or otherwise.
Additionally, nothing in this paragraph shall limit the Manager's right to
recover any other damages to which it is entitled as result of Medical
Practice's breach. If any provision of the restrictive covenants is held by a
court of competent jurisdiction to be unenforceable due to an excessive time
period, geographic area, or restricted activity, the restrictive covenant shall
be reformed to comply with the time period, geographic area, or restricted
activity that would be held enforceable.

V.  FINANCIAL ARRANGEMENT.

<PAGE>
 
          5.1 REIMBURSEMENT OF EXPENSES.  Medical Practice shall reimburse the
Manager for all out of pocket expenses, direct costs, and reasonable indirect
costs paid or incurred by the Manager on behalf of Medical Practice.

          5.2 AMOUNT OF MANAGEMENT FEES.

              5.2-1 Medical Practice and the Manager mutually recognize and
acknowledge that the Manager will incur substantial costs and business risks in
arranging for Medical Practice's use of the Office and in providing the
equipment, support services, personnel, marketing, office space, management,
administration, and other items and services that are the subject matter of this
Agreement.  Medical Practice and the Manager further recognize that certain of
such costs and expenses can vary to a considerable degree according to the
extent of Medical Practice's business and services.  It is the intent of the
parties that the fees paid to the Manager be reasonable and approximate its
costs and expenses plus a reasonable return considering the investment and risk
taken by the Manager and the value of the services provided by the Manager.  In
addition to the reimbursement of expenses and costs described in Section 5.1
above, Medical Practice shall pay to the Manager a Management Fee as described
in Exhibit A attached hereto and incorporated into this Agreement.

              5.2-2 The Management Fee amount shall be re-evaluated on not less
than a yearly basis in the anniversary month of the execution of this Agreement
or as changes in the Medical Practice dictate, to ensure that the Management Fee
reflects the fair market value of the Manager's services.  Payment of the
Management Fee is not intended to be and shall not be interpreted or applied as
permitting the Manager to share in Medical Practice's fees for Medical Services
or any other services but is acknowledged as the parties' negotiated agreement
as to the reasonable fair market value of the equipment, support services,
personnel, marketing, office space, management, administration, and other items
and services furnished by the Manager pursuant to this Agreement, considering
the nature and volume of the services required and the risks assumed by the
Manager.

              5.2-3 Notwithstanding the above, the Fixed Fee shall
increase each year by no less than the greater of five percent (5%) of the
increase in the Consumer Price Index for all Urban Consumers.

          5.3 PAYMENT OF MANAGEMENT FEE.  To facilitate the payment of the
Management Fee and the reimbursement of expenses, Medical Practice expressly
authorizes the Manager to withdraw the Management Fee and other amounts due to
the Manager as reimbursement of expenses from the Medical Practice Account, from
time to time at Manager's sole discretion.

          5.4 ADJUSTMENTS. Adjustments to the Management Fee calculation shall
be made as follows:

              5.4-1 Upon termination of this Management Services Agreement, a
liability for the Management Fee shall be established in an amount equal to the
difference, if any

                                       16
<PAGE>
 
between (i) ** CONFIDENTIAL INFORMATION ** less (ii)** CONFIDENTIAL INFORMATION
**.

              5.4-2 If there are not sufficient funds to pay the Bonus Fee,
unpaid amounts ** CONFIDENTIAL INFORMATION **. Furthermore, the amount of the
Bonus Fee paid will be monitored and reconciled on an annual basis and any
overpayments of the Bonus Fee shall be promptly refunded by the Manager.

          5.5 ACCOUNTS RECEIVABLE.  To assure that Medical Practice receives the
entire amount of professional fees for its services and to assist Medical
Practice in maintaining reasonable cash flow for the payment of Office Expenses,
Manager shall, during the Term, purchase,              ** CONFIDENTIAL
INFORMATION **, the accounts receivable of Medical Practice arising during the
previous month by transferring the amount set forth below into the Medical
Practice Account.  The consideration for the purchase shall be **CONFIDENTIAL
INFORMATION**. Manager shall be entitled to offset expense reimbursement and
Management Fees due to Manager against the amount payable for the accounts
receivable.  If and to the extent Manager determines an account to be
uncollectible, Manager shall  ** CONFIDENTIAL INFORMATION **. Although it is the
intention of the parties that Manager purchase and thereby become the owner of
the accounts receivable of Medical Practice, in the event such purchase shall be
ineffective for any reason, Medical Practice is concurrently herewith granting
to Manager a security interest in the accounts receivable, and Medical Practice
shall cooperate with Manager and execute all documents in connection with the
pledge of such accounts receivable to Manager.  All collections in respect to
such accounts receivable purchased by Manager shall be received by Manager as
the agent of Medical Practice and shall be endorsed to ** CONFIDENTIAL
INFORMATION ** and deposited in a bank account at a bank ** CONFIDENTIAL
INFORMATION **.  To the extent ** CONFIDENTIAL INFORMATION ** comes into
possession of any payments in respect of such accounts receivable,
** CONFIDENTIAL INFORMATION ** shall direct such payments to ** CONFIDENTIAL
INFORMATION ** for deposit in bank accounts ** CONFIDENTIAL INFORMATION **.

              5.5-1 The Medical Practice will execute a Promissory Note
and Security Agreement (in substantially the forms as are attached as Exhibit B
and C, respectively), plus any other documentation reasonably required by
Manager to evidence and secure the advances ("Advances") against all tangible
and intangible assets of Medical Practice, including, but not limited to, its
accounts receivable.

              5.5-2 The Medical Practice acknowledges that Manager is
borrowing the funds to make the Advances from a third party lender.  Medical
Practice consents to the assignment of the Promissory Note and Security
Agreement to the third party lender and agrees to execute all documents
reasonably necessary or required by the third party lender to evidence such
assignment. Medical Practice also agrees to execute and deliver all
documentation reasonably necessary and required by the third party lender to
evidence Manager's and the third party lender's security interest in all
accounts in which the ** CONFIDENTIAL INFORMATION **.

VII.  MISCELLANEOUS.

      7.1 ADMINISTRATIVE SERVICES ONLY.  Nothing in this Agreement is intended
or shall be construed to allow the Manager to exercise control or direction over
the manner or method by which Medical Practice and its Physicians perform
Medical Services or other professional health-care services.  The rendition of
all Medical Services, including, but not limited to, emergency medicine and the
prescription or administration of medicine and drugs, shall be the sole
responsibility of Medical Practice and its Physicians, and the Manager shall not
interfere in any manner or to any extent therewith.  Nothing in this Agreement
shall be construed to permit the Manager to engage in the practice of medicine,
it being the sole intention of the parties that the services to be rendered to
Medical Practice by the Manager are solely for the purpose of providing
nonmedical management and administrative services to Medical Practice so that
Medical Practice can devote its full time and energies to the professional
conduct of its medical practice and to the provision of Medical Services to its
patients and not to administration, marketing, or practice management.

      7.2 STATUS OF CONTRACTOR.  It is expressly acknowledged that the parties
are independent contractors, and nothing in this Agreement is intended and
nothing shall be construed to create an employer-employee, partnership, joint-
venture, or other type of relationship, or to allow either party to exercise
control or direction over the manner or method by which the other performs the
services that are the subject matter of this Agreement; provided always that the
services to be provided under this Agreement shall be furnished in a manner
consistent with the standards governing those services and the provisions of
this Agreement.   Each party understands and agrees that (i) the other will not
be treated as an employee for federal tax purposes, (ii) neither will withhold
on behalf of the other any sums for income tax, unemployment insurance, social
security, or any other withholding pursuant to any law or requirement of any
governmental body or make available any of the benefits afforded to its
employees, (iii) all of such payments, withholdings, and benefits, if any, are
the sole responsibility of the party incurring the liability, and (iv) each will
indemnify and hold the other harmless from any and all loss or liability arising
with respect to such payments, withholdings, and benefits, if any.

      7.3 NOTICES.  Any notice, demand, or communication required, permitted, or
desired to be given under this Agreement shall be deemed effectively given when
in writing and personally delivered or mailed by prepaid certified or registered

Agreement to any third party and (ii) collaterally to assign its interest in

any financial institution or other third party without the consent of Medical
Practice.

      7.6 WAIVER OF BREACH.  The waiver by either party of a breach or violation

further agreement by the parties; provided, however, at the request of either
party, the other party shall execute any additional instruments and take any
additional acts that are reasonable and that the requesting party may deem
necessary to effectuate this Agreement.

      7.10 CONSENTS, APPROVALS, AND EXERCISE OF DISCRETION.  Whenever this
Agreement requires any consent or approval to be given by either party or either
party must or may exercise discretion, the parties agree that the consent or
approval shall not be unreasonably withheld or delayed and that the discretion
shall be reasonably exercised.

      7.11 DISPUTE RESOLUTION.  Manager and Managing Physician shall use
good faith negotiation to resolve any dispute that may arise under this
Agreement.  In the event Manager and Managing Physician cannot reach agreement
on any issue, Medical Practice shall call a meeting of its partners, who shall
vote on whether to agree with Manager or Managing Physician on the issue in
dispute.  If the partners vote to agree with the Managing Physician, and the
parties remain in disagreement, the issue shall be submitted by either party to
binding arbitration according to the rules of arbitration of the National Health
Lawyers Association.  Arbitration shall take place in Houston, Texas.

      7.12 FORCE MAJEURE.  Neither party shall be liable or deemed to be

performance is expressly addressed elsewhere in this Agreement.

      7.13 SEVERABILITY.  The parties have negotiated and prepared the
terms of this Agreement in good faith and with the intent that every term,
covenant, and condition be binding upon and inure to the benefit of the
respective parties.  Accordingly, if any one or more of the terms, provisions,
promises, covenants, or conditions of this Agreement or the application thereof
to any person or circumstance shall be adjudged to any extent invalid,
unenforceable, void, or voidable for any reason whatsoever by a court of
competent jurisdiction, that provision shall be as narrowly construed as
possible, and all the remaining terms, provisions, promises, covenants, and
conditions of this Agreement or their application to other persons or
circumstances shall not be affected thereby and shall be valid and enforceable
to the fullest extent permitted by law.  To the extent this Agreement is in
violation of applicable law, then the parties agree to negotiate in good faith
to amend the Agreement, to the extent possible consistent with its purposes, to
conform to applicable law.

      7.14 DIVISIONS AND HEADINGS.  The divisions of this Agreement into
articles, sections, and subsections and the use of captions and headings in

                         COLLECTION SERVICES AGREEMENT
                         -----------------------------


     THIS COLLECTION SERVICES AGREEMENT ("Agreement") is made and entered into
effective as of the 1st day of March, 1995 ("Effective Date"), by and between
DRCA Houston Clinics, Inc., a Texas corporation ("Collection Agent"), and
Northshore Orthopedics Assoc., a Texas professional association ("Medical
Practice").

                                   RECITALS:

     This Agreement is made with reference to the following facts:

     A.  Medical Practice is a validly existing Texas professional association
formed for and engaged in the conduct and provision of medical services to the
general public in the State of Texas through physicians who are licensed to
practice medicine in the State of Texas and who are employed or otherwise
retained by Medical Practice.

     B.  Collection Agent is a validly existing Texas corporation that provides
administrative and related services to professional associations, physicians,
and other professional health care entities and individuals.  Collection Agent's
personnel are experienced in providing collection services for medical
practices.
 
     C.   Medical Practice wishes to engage Collection Agent to provide
collection services for Medical Practice, and Collection Agent desires to
provide such services, all upon the terms and conditions hereinafter set forth.

     D.   Medical Practice and Collection Agent have negotiated at arms-length
and determined a fair market value for the services to be rendered by Collection
Agent.  Based on this fair market value, Medical Practice and Collection Agent
have developed a formula to compensate Collection Agent that will allow the
parties to establish a relationship permitting each party to devote its skills
and expertise to the appropriate responsibilities and functions.

     NOW, THEREFORE, in consideration of the mutual terms, covenants and
conditions hereinabove and hereinafter set forth, the parties agree as follows:

I.  APPOINTMENT AND AUTHORITY OF COLLECTION AGENT.
    --------------------------------------------- 

      1.1  APPOINTMENT.  Medical Practice appoints Collection Agent as its sole
and exclusive agent for the provision of collection services on behalf of
Medical Practice, except as otherwise
<PAGE>
 
specifically agreed in writing by Medical Practice and Collection Agent, and
Collection Agent accepts the appointment, subject at all times to the provisions
of this Agreement.

      1.2  AUTHORITY.

     A.  Consistent with the provisions of this Agreement, Collection Agent
shall have the responsibility and commensurate authority to provide collection
services on behalf of Medical Practice.  In satisfying its obligations
hereunder, Collection Agent may perform any service or provide any material
directly or Collection Agent may engage an affiliate to perform any service or
provide any material.

     B.  Collection Agent will have no involvement in nor exercise any control
over Medical Practice's internal activities and management decisions, including,
but not limited to, decisions regarding Medical Practice membership or the
manner or method by which Medical Practice conducts its salary allocation.

     1.3  PATIENT REFERRALS.  Collection Agent and Medical Practice agree that
the benefits to Medical Practice hereunder do not require, are not payment for,
and are not in any way contingent upon a referral or any other arrangement for
the provision of any item or service offered by Collection Agent or any entity
affiliated with Collection Agent of any patient of Medical Practice to any
entity controlled, managed, or operated by Collection Agent.

II.  COVENANTS AND RESPONSIBILITIES OF COLLECTION AGENT

     2.1   COLLECTION.  On behalf of and for the account of Medical Practice,
Collection Agent shall establish and maintain collection policies and
procedures, and shall use Collection Agent's reasonable best efforts to collect
timely all professional and other fees for all billable medical services
provided by Medical Practice or its physicians as such amounts are represented
in Medical Practice's accounts receivable ledger dated 2/28/95, which amounts
represent all uncollected billable services of the Medical Practice as of the
date hereof, a copy of which is attached as Exhibit A (the "Accounts
Receivable").  Collection Agent shall not consult with Medical Practice
regarding the fees for medical services provided by Medical Practice; it being
understood that Medical Practice shall establish the fees to be charged for
medical services, and that Collection Agent shall have no authority whatsoever
with respect to the establishment of such fees.  In connection with the
collection services to be provided hereunder, and throughout the term of this
Agreement (and thereafter as provided in Section 5.3), Medical Practice grants
Collection Agent a special power of attorney and appoints Collection Agent as
Medical Practice's true and lawful agent and attorney-in-fact, and Collection
Agent accepts such special power of attorney and appointment, for the following
purposes:

     A.  To collect and receive, in Medical Practice's name and on Medical
Practice's behalf, all Accounts Receivable, to administer such accounts
including, but not limited to, extending the time of payment of any such
accounts for cash, credit or otherwise; discharging or releasing the obligors of
any such accounts; suing, assigning or

                                       2
<PAGE>
 
selling at a discount such accounts to collection agencies; or taking other
measures to require the payment of any such accounts Medical Practice shall be
responsible for fees, if any, to outside collection agencies.

     B.  To deposit all amounts collected into the bank account of Medical
Practice established pursuant to this Agreement ("Medical Practice Account"),
which shall be and at all times remain in Medical Practice's name.  Medical
Practice covenants to transfer and deliver to Collection Agent all funds
received by Medical Practice from patients or third-party payers for medical
services.  Upon receipt by Collection Agent of any funds from patients or third-
party payers or from Medical Practice for medical services, Collection Agent
shall immediately deposit the funds into the Medical Practice Account.
Collection Agent may draw checks on the Medical Practice Account as expressly
authorized herein. Medical Practice will not withdraw funds from the Medical
Practice Account without the prior written consent of Collection Agent.  Limits
on authority to sign checks shall be mutually agreed upon by Collection Agent
and Medical Practice; and

     C.  To take possession of, endorse in the name of Medical Practice, and
deposit into the Medical Practice Account any notes, checks, money orders,
insurance payments, and any other instruments received in payment of accounts
receivable for medical services.

Collection Agent shall have access to the Medical Practice Account solely for
the purposes stated in this Agreement.  Upon request of Collection Agent,
Medical Practice shall execute and deliver to the financial institution wherein
the Medical Practice Account is maintained any additional documents or
instruments that may be necessary to evidence or effect the special power of
attorney granted to Collection Agent by Medical Practice pursuant to this
Section.  The special power of attorney granted in this Agreement shall be
coupled with an interest and shall be irrevocable except with Collection Agent's
written consent.

shall prepare and send to Medical Practice Collection Agent's standard monthly
collection reports for the previous month.

upon procedure, including documentation, for the request, use, maintenance, and
return of Medical Practice's patient files.

     2.4  ASSUMPTION OF CERTAIN COSTS.  Collection Agent shall assume all costs
for postage, phone bills, forms, and supplies used by Collection Agent.

     2.5  CONFIDENTIALITY.  Collection Agent agrees to keep confidential and not
to take, retain, use, or disclose to others during the term of this Agreement
and for a period of two (2) years thereafter, except as expressly consented in
writing by Medical Practice or by law, any secrets or confidential technology,
proprietary information, strategic plans, patient lists or records, documents
pertaining to Medical Practice's business or financial conditions, trade secrets
of

                                       3

Medical Practice, or any matter or thing ascertained by Collection Agent through
Collection Agent's relationship with Medical Practice, the use or disclosure of
which matter or thing might reasonably be construed to be contrary to the best
interests of Medical Practice.  Collection Agent further agrees that upon
termination or expiration of this Agreement, Collection Agent and each and every
one of its members, partners, employees, contractors, or agents will neither
take nor retain, without prior written authorization from Medical Practice, any
papers, patient lists, fee books, files, or other documents or copies thereof or
other confidential information of any kind belonging to Medical Practice or
pertaining to Medical Practice's patients, business, financial condition, or
products.  Without limiting other possible remedies to Medical Practice for the
breach of this covenant, Collection Agent agrees that injunctive or other
equitable relief shall be available to enforce this covenant regarding
confidentiality of information.

     2.6  INDEMNIFICATION BY COLLECTION AGENT.  To the extent not otherwise
covered by insurance, Collection Agent shall indemnify and hold harmless Medical
Practice from and against any and all liability, losses, damages, claims, causes
of action, and expenses, including reasonable attorney's fees, associated with
or directly or indirectly resulting from any act or omission of Collection Agent
or the personnel under its supervision.  To be entitled to such indemnification,
Medical Practice shall give Collection Agent prompt written notice of the
assertion by a third party of any claim with respect to which Medical Practice
might bring a claim for indemnification hereunder, and in all events must
provide such written notice to Collection Agent within the applicable period for
defense of such claim by Collection Agent.  Collection Agent shall have the
right to defend and litigate any such third-party claim.

III.  MEDICAL PRACTICE RESPONSIBILITIES AND OBLIGATIONS.

     3.1  ORGANIZATION AND OPERATION.  Medical Practice, as a continuing
condition of Collection Agent's obligations under this Agreement, shall at all
times during the term of this Agreement be and remain legally organized and

action, and expenses, including, without limitation, reasonable attorney's fees
and associated costs, associated with or directly or indirectly resulting from
any act or omission of Medical Practice, its employees, agents, or independent
contractors during the term of this Agreement.  To be entitled to such
indemnification, Collection Agent shall give Medical Practice prompt written
notice of the assertion by a third party of any claim with respect to which
Collection Agent might bring a claim for indemnification hereunder, and in all
events must provide written notice to Medical Practice within the applicable
period for defense of such claim by Medical Practice.  Medical Practice, at its
own expense, has the right to defend and litigate any such third-party claim.

acknowledges the confidentiality of its relationship with Collection Agent and
of any confidential information of which it may learn or obtain during the term
of this Agreement.  Medical Practice agrees to keep confidential and not to

Agent's business or financial conditions (including the terms of this
Agreement), trade secrets of Collection Agent, or any matter or thing
ascertained by Medical Practice through Medical Practice's relationship with
Collection Agent, the use or disclosure of which matter or thing might
reasonably be construed to be contrary to the best interests of Collection
Agent.  Medical Practice further agrees that upon termination or expiration of
this Agreement, Medical Practice and each and every of its members, partners,

enforced in its place and remaining restrictions contained herein shall be
enforced independently of each other.

all medical services shall be the sole responsibility of Medical Practice and
its physicians, and Collection Agent shall not interfere in any manner or to any
extent therewith.  Nothing in this Agreement shall be construed to permit
Collection Agent to engage in the practice of medicine.  Collection Agent
renders solely nonmedical collection services to Medical Practice so that
Medical Practice can devote its full time and energies to the professional
conduct of its medical practice and to the provision of medical services to its
patients.

Physician's obligations under Section 3.2.  Physicians who provide services on
behalf of Physician shall be employees or independent contractors of Physician.
Physician shall be responsible for recruiting, contracting, scheduling,
compensating and supervising all such other physicians; however, prior approval
of any physician providing coverage for Physician must be obtained from DRCA.
Physicians engaged by Physician shall meet the same license, certification and
membership requirements required of Physician under this Agreement and shall
have and maintain professional insurance in a type and amount equivalent to that
which Physician is required to have and maintain under Section 3.5.

     3.5  INSURANCE.  Physician and all physicians who may provide services
hereunder for Physician will at all times throughout the term of this Agreement
maintain general and professional liability insurance, including malpractice
insurance, in an amount no less than One Million Dollars ($1,000,000) per
occurrence for each claim and Three Million Dollars ($3,000,000) annual
aggregate.  Such insurance shall be obtained from a reputable insurance company
authorized to sell liability insurance policies in Texas, rated A or better and
satisfactory to DRCA.  Such insurance may be in a combination of primary and
excess amounts.  Moreover, in the event that Physician (or any physician
providing services hereunder for Physician) ceases to provide services
hereunder, or upon the termination or expiration of this Agreement, Physician
and each physician whose insurance is "claims made" insurance rather than
"occurrence" insurance will either (i) purchase "tail" coverage to continue the
liability insurance coverage for the period during which Physician or any
physician rendered services hereunder or (ii) continue in full force and effect
the same level of liability insurance coverage on a claims made basis until the
longest

                                       3
<PAGE>
 
statute of limitations for professional liability has expired (recognizing that
the statute of limitations for minors is tolled until they reach the age of
majority).  This requirement shall be deemed continuing and shall survive any
termination or expiration of this Agreement.  Said insurance shall cover all of
Physician's professional services provided to patients, his private medical
practice, as well as his activities and responsibilities as a member of the
Medical Staff of the Medical Practice.  On or before the effective date of this
Agreement and thereafter on the first day of each year of the term of this
Agreement, Physician and each physician will deliver to DRCA a certificate of
insurance evidencing the required coverage and the payment of premiums by
Physician for the ensuing year.  Physician's insurer or insurers shall provide
written notice to DRCA of the cancellation or proposed cancellation of any such
liability insurance policy.

     3.6  DISCLOSURE OF INFORMATION.  Physician recognizes and acknowledges that
he will have access to certain confidential information of DRCA and that such
information constitutes valuable, special and unique property of DRCA.
Physician will not, during or after the term of this Agreement, without the
consent of DRCA, disclose any such confidential information to any other person,
