ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Company's Certificate of Incorporation and By-laws provide for
indemnification of directors, officers, agents, and employees of the Company to
the fullest extent permitted by law. Under Delaware law, a corporation may
indemnify any person who was or is a party or is threatened to be made a party
to an action (other than an action by or in the right of the corporation) by
reason of his service as a director or officer of the corporation, or his
service, at the corporation's request, as a director, officer, employee or agent
of another corporation or other enterprise, against expenses (including
attorneys' fees) that are actually and reasonably incurred by him ("Expenses"),
and judgments, fines and amounts paid in settlement that are actually and
reasonably incurred by him, in connection with the defense or settlement of such
action, provided that he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the corporation's best interests and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
that his conduct was unlawful. Although Delaware law permits a corporation to
indemnify any person referred to above against Expenses in connection with the
defense or settlement of an action by or in the right of the corporation,
provided that he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the corporation's best interests, if such person has
been judged liable to the corporation, indemnification is only permitted to the
extent that the Court of Chancery (or the court in which the action was brought)
determines that, despite the adjudication of liability, such person is entitled
to indemnity for such Expenses as the court deems proper. The determination as
to whether a person seeking indemnification has met the required standard of
conduct is to be made (1) by a majority vote of a quorum of disinterested
members of the board of directors, or (2) by independent legal counsel in a
written opinion, if such a quorum does not exist or if the disinterested
directors so direct, or (3) by the stockholders. The General Corporation Law of
the State of Delaware also provides for mandatory indemnification of any
director, officer, employee or agent against Expenses to the extent such person
has been successful in any proceeding covered by the statute. In addition, the
General Corporation Law of the State of Delaware provides the general
authorization of

                                                        II-1

<PAGE>



advancement of a director's or officer's litigation expenses in lieu of
requiring the authorization of such advancement by the board of directors in
specific cases, and that indemnification and advancement of expenses provided by
the statute shall not be deemed exclusive of any other rights to which those
seeking indemnification or advancement of expenses may be entitled under any
bylaw, agreement or otherwise.

ITEM 17.  UNDERTAKINGS.

         The undersigned Registrant hereby undertakes:


                                                        II-4

<PAGE>



         (1) To provide to the Underwriters at the closing specified in the
Purchase Agreement certificates in such denominations and registered in such
names as required by the Underwriters to permit prompt delivery to each
purchaser.

         (2) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

         (3) For purposes of determining any liability under the Securities Act
of 1933, the information omitted from the form of prospectus filed as part of a
registration statement in reliance upon Rule 430A and contained in the form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of the registration
statement as of the time it was declared effective.

         (4) For the purpose of determining any liability under the Securities
Act of 1933, each post-effective amendment that contains a form of prospectus
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

         THIS ASSET PURCHASE  AGREEMENT  ("Agreement")  is entered into this the
19th day of January,  1996, by and among ABILENE DIAGNOSTIC CLINIC,  P.L.L.C., a
professional  limited liability company organized under the laws of the State of
Texas  (hereinafter  referred  to  as  "ADC"),  PROMEDCO,  INC.,  a  corporation
organized  under  the laws of the  State of Texas  (hereinafter  referred  to as
"ProMedCo")  and PROMEDCO OF ABILENE,  INC., a corporation  organized  under the
laws of the State of Texas (hereinafter referred to as "POA").

                                 WITNESSETH:

         WHEREAS,  ADC is the owner and operator of a group medical  practice in
Taylor County,  Texas  ("Practice")  and is engaged in the practice of providing
medical care to patients;

         WHEREAS, ProMedCo, through its 100% owned subsidiary POA, is engaged in
the business of providing medical practice facilities, nonmedical personnel, and
medical practice management and administrative  services (ProMedCo and POA being
herein collectively referred to as "Purchaser");

     WHEREAS,  ADC wishes to transfer  certain of the Practice  Assets to POA in
exchange for voting shares of ProMedCo; and

     WHEREAS,  the  parties  desire  to set  forth  in  writing  the  terms  and
conditions under which said exchange will be consummated.

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
set forth  herein,  and other good and valuable  consideration,  the receipt and
sufficiency  of which are hereby  acknowledged  by the parties,  it is agreed as
follows:

                                  ARTICLE I.
                         PURCHASE OF CERTAIN ASSETS

        1.1       Purchase of Certain Assets.  On the Closing Date (as hereafter
defined) ProMedCo and POA shall acquire from ADC certain of the Practice assets
(the "Practice Assets") of ADC.  The Practice Assets shall be more particularly
described on Exhibit 1. 1.

        The Practice  Assets shall include,  but not be limited to ADC's certain
accounts receivable,  furnishings and equipment that are currently covered under
the Hospital Agreements referenced in Section 1.5. The furnishings and equipment
subject to the  Hospital  Agreements  shall  become the property of POA upon the
reimbursement  of ADC by POA for the cost of the  furnishings  and  equipment as
specified  in the  purchase  option  detailed in the  Hospital  Agreements.  The
reimbursement of ADC by POA, in the event that the Hospital  Agreements complete
their initial terms, shall be the reacquisition  price incurred by ADC according
to the Hospital Agreements for furnishings,  equipment and replacements  thereof
purchased by the hospitals prior to January 17, 1996,  plus any furnishings, 
equipment and replacements thereof that were

<PAGE>



purchased pursuant to the Hospital  Agreements after January 17, 1996, that were
approved by the Policy Council,  as defined in that Interim  Services  Agreement
between the parties dated January 19, 1996 (the "Interim  Services  Agreement").
In the event that the Hospital Agreements are terminated,  with or without cause
by  ADC  prior  to the  initial  term  of  the  Hospital  Agreements,  then  the
reimbursement  of ADC by POA  shall  be  limited  to ten  percent  (10%)  of the
original  acquisition  price of such  furnishings,  equipment  and  replacements
thereof  that were  purchased  pursuant  to such  Hospital  Agreements  prior to
January 17, 1996, plus the reacquisition  price,  according to the terms of such
Hospital Agreements, of any furnishings, equipment and replacements thereof that
were purchased pursuant to such Hospital  Agreements after January 17, 1996, and
that were  approved by the Policy  Council,  as defined in the Interim  Services
Agreement.

        In either case above,  the  reimbursement of ADC by POA shall be reduced
by the  reacquisition  price of any assets  associated  with any  physicians who
became members of ADC concurrent  with the formation of ADC on January 17, 1996,
and who sold their  assets to either  local  hospital  according to the Hospital
Agroctnents, subsequent to January 17, 1996.

exercise its option to repurchase the equipment  owned by the hospital under the
Hospital Agreements.

interest in and  possession of the  financial  books and records of ADC shall be

preparing for federal, state and local tax audits, any governmental  enforcement
procedures  or  preparing  for the  defenses of any claims,  causes of action or
other  similar  matters;  provided  however,  POA shall provide one copy of such
financial books and records to ADC as are sufficient for ADC to maintain its own
books and records at Closing at no cost.

        1.3 Assumption of Certain Liabilities. At the Closing, POA shall assume,
pay, perform and discharge only the liabilities of ADC set forth on Exhibit 1.3.
To the  extent  POA  assumes  any  liabilities,  ADC must pay cash  equal to the

transaction herein contemplated;

         (d) any liability  arising out of any employee benefit plans maintained

liabilities of ADC not expressly  assumed by POA and that POA shall have a right
of offset as set forth in Section 1.7.

          1.5 Service Agreement.  At the time of the Closing,  ADC and POA shall
have entered into a Service Agreement ("Service  Agreement") to be effective the
later date of (a) February 16, 1997 or (b) the first day of the month  following
the  date of the  Initial  Public  Offering  ("IPO")  of  ProMedCo,  in the form
attached as Exhibit 1.5 (the  "Effective  Date").  This  Agreement  is different
from,  and shall not  effect  the terms of,  that  certain  Practice  Management
Agreement by and between Southwestern Health Development Corporation and Abilene
Diagnostic Clinic  Associates,  P.A. ("PA"), a Texas  professional  association,
dated as of October 13, 1993, and that certain Practice Management  Agreement by
and between Abilene  Medical  Management  Services,  Inc. and PA dated as of the
June 20, 1994, (collectively the "Hospital Agreements").


         1.6   Collection of Accounts Receivable.  ADC agrees to cooperate with
POA in the collection of the Accounts Receivable transferred pursuant to 
Section 1.1.

          1.7 Right of Offset.  In  addition  to all other  rights and  remedies
available to POA at law or in equity, and notwithstanding any other provision of
this  Agreement to the contrary,  POA may offset against any amounts it owes ADC
under this Agreement, the Services Agreement, or any other agreement any amounts
due POA due to a failure of ADC to perform any indemnity pursuant to Section 10,
or  created  by  POA's  payment  of any ADC  liability.  In the  event  that POA
determines that an amount is to be so offset,  as a condition  precedent to such
right of  offset,  POA  shall  give ADC  written  notice  of the  amount of such
proposed offset and the basis  therefore  within thirty (30) days after the date
on which  such  amount is  finally  determined.  If POA shall not have  received
written notice from ADC contesting  such offset within thirty (30) days of their
receipt of such

<PAGE>



written notice from POA, the offset shall be deemed to have been consented to by
ADC and POA shall be entitled to deduct the entire  amount  claimed as an offset
from the  agreements  referenced  within this Section 1.7. In the event that ADC
shall object to the  proposed  offset by written  notice  received by POA during
such thirty (30) day period,  the entitlement of POA to the claimed offset shall
be determined by arbitration as described in Section 18.10.

        In the event that any offset is determined to be due POA, and POA elects
to offset that amount against any stock due ADC pursuant to this Agreement, then
the basis of value for that stock shall be its fair market  value on the date of
offset for purposes of satisfying the amount of the offset.

        1.8  Occasional  Sale. ADC and Purchaser  believe that the  transactions
contemplated by this Agreement  constitute the sale of an entire  operating unit
or a separate  division  or a  separate  identifiable  segment of a division  in
accordance with Section 151.304(b)(2) of the Texas Tax Code and Section 3.316(d)
of Title 34 of the Texas  Administrative  Code, and, therefore,  the sale of any
and all items of tangible personal property to POA pursuant to this Agreement is
exempt  from any and all  state and  local  sales and use tax.  In the event the
transactions contemplated by this Agreement do not qualify for such exemption or
other applicable exemption, and the State of Texas seeks to collect sales or use
tax under the Texas Tax Code,  Purchaser shall be liable and responsible for any
such tax. ADC agrees to cooperate with Purchaser in connection with any audit of
this transaction regarding the application of the sales tax law thereto.

                                 ARTICLE II.

to 20% of the shares  extending to any  secondary  offerings for five (5) years.
The  piggyback  rights are subject to  limitations  from  underwriters,  and any
restrictions would be shared pro rata with others that have similar rights.

<PAGE>



be  distributed  at the  Closing  Date shall be adjusted  downward.  The rate of
adjustment  shall be a reduction  of 3.57 Shares  (rounded to the nearest  whole
number) for every 1 share affecting ADC that is limited by underwriters.

accounts receivable as of the Execution Date.

        2.3  Stockholders  Agreement.  The Shares shall be issued subject to the
Stockholders Agreement datedas of the Closing Date ("Stockholders  Agreement") a
copyofwhich  is  attachedas  Exhibit  2.3 and which shall be executed by ADC and
ProMedCo.  ADC understands  that ADC only will be allowed to transfer the Shares
in accordance with the  Stockholders  Agreement.  ADC also  understands that any
document  evidencing  the  Shares  will bear a  restrictive  legend  prohibiting
transfer other than in accordance with the Stockholders Agreement.

    2.4 Tax. All transfer and similar taxes, fees and assessments  incurred as a
result of the transactions contemplated by this Agreement shall be paid by ADC.

        2.5 Allocation of Purchase Price.  The Purchase Price shall be allocated
to the Assets and shall be reported for tax  purposes by each party,  consistent
with a method mutually agreed upon by  representatives of ADC, ProMedCo and POA.
If ADC,  ProMedCo and POA are unable to agree, a "Big Six" accounting firm shall
be engaged to allocate the Purchase Price equitably.

                                 ARTICLE III.

                                   CLOSING

        The purchase of the Practice Assets as  contemplated  hereby shall close
("Closing")  by the later of: (a) February 16, 1997; or (b) the first day of the

         6.10     Employee Benefit Plans.

                  (a) List of Plans.  Set forth on Exhibit  6.10 is an  accurate
and complete  list of all employee  benefit  plans  ("Employee  Benefit  Plans")
within the meaning of Section 3(3) of the Employee  Retirement  Income  Security
Act of 1974, as amended ("ERISA"), whether or not any Employee Benefit Plans are
otherwise  exempt  from the  provisions  of ERISA,  established,  maintained  or
contributed  to by ADC,  including all employers  (whether or not  incorporated)
which by reason of common  control  are  treated  together  with ADC as a single
employer within the meaning of Section 414 of the Code since September 2, 1974.

                  (b) Status of Plans. ADC has never maintained and does not now
maintain or  contribute  to any Employee  Benefit Plan subject to ERISA which is
not in substantial  compliance with ERISA, or which has incurred any accumulated
funding  deficiency within the meaning of Section 412 or 418B of ERISA, or which
has applied for or obtained a waiver from the  Internal  Revenue  Service of any
minimum funding requirement under Section 412 of the Code or which is subject to
Title IV of ERISA.  ADC has not  incurred any  liability to the Pension  Benefit
Guaranty  Corporation  ("PBGC") in  connection  with any  Employee  Benefit Plan
covering any employees of ADC or ceased  operations at any facility or withdrawn
from any such Plan in a manner which could subject it to liability under Section
4062(f),  4063 or 4064 of ERISA,  and knows of no facts or  circumstances  which
might give rise to any liability of ADC to the PBGC under Tide IV of ERISA which
could  reasonably  be  anticipated  to result in any claim  being  made  against
Purchaser by the PBGC. ADC has not incurred any withdrawal liability (including


<PAGE>



any contingent or secondary withdrawal liability) within the meaning of Sections
4201 and 4202 of ERISA,  to any Employee  Benefit Plan which is a  Multiemployer
Plan (as defined in Section 4001 of ERISA), and no event has occurred, and there
exists no condition or set of circumstances, which represents a material risk of
the  occurrence  of  any   withdrawaL-from   or  the   partition,   termination,
reorganization or insolvency of any Multiemployer Plan which would result in any
liability to a Multiemployer Plan.

                (c)  Contributions.  Full  payment  has been made of an  amounts
which ADC is required,  under  applicable law or under any Employee Benefit Plan
or any agreement  relating to any Employee Benefit Plan to which ADC is a party,
to have  paid as  contributions  thereto  as of the last day of the most  recent
fiscal year such Employee  Benefit Plan ended prior to the date hereof.  ADC has
made adequate  provision for reserves to meet  contributions  that have not been
made because  they are not yet due under the terms of any Employee  Benefit Plan
or  related  agreements.  Benefits  under  all  Employee  Benefit  Plans  are as
represented  and  have  not been  increased  subsequent  to the date as of which
documents have been provided.

                (d) Tax Qualification. Each Employee Benefit Plan intended to be
qualified  under  Section  401 (a) of the  Code  has  been  determined  to be so
qualified by the  Internal  Revenue  Service and nothing has occurred  since the
date of the last such  deten-nination  which  resulted or is likely to result in
the revocation of such determination.

                (e)  Transactions.  ADC has not engaged in any transaction  with
respect to the Employee  Benefit Plans which would subject it to a tax,  penalty
or liability for prohibited  transactions  under ERISA or the Code.  Neither ADC
nor any of its employees, to the extent they or any of them are fiduciaries with
respect to such plans, have breached any of the  responsibilities or obligations
imposed upon fiduciaries under Title I of ERISA, nor have they taken any actions
which would  result in any claim being made under or by or on behalf of any such
plans by any party with standing to make such claim.

                (f)  Other Plans.  ADC presently does not maintain any employee
benefit plans or any other foreign pension, welfare or retirement benefit
plans other than those listed on Exhibit 6.10.

                (g)  Documents.  ADC has  delivered or caused to be delivered to

Plans as in effect,  together  with all  amendments  thereto  which will  become

determination  letter  obtained with respect to any such  Employee  Benefit Plan
qualified  under Section 401 or 501 of the Code, and (ii) Form 5500 for the most
recent  completed  fiscal year for each  Employee  Benefit Plan required to file

material  disagreements with any third parties with which it does business,  and
ADC will use its best efforts from the date of this Agreement  until the Closing

contained  herein,  no  representation or warranty made by ADC in this Agreement
contains or will  contain any untrue  statement  of a material  fact or omits or
will omit or fail to state a  material  fact  necessary  to make the  statements
contained herein or therein not materially misleading;  provided, 'however, that

liabilities  associated  with  ADC's  Practice.  ADC  has no  other  liabilities

opportunity  to ask  questions of its officers and directors and to acquire such
additional information about the Shares and the business and financial condition

<PAGE>



                (b) In  deciding  to acquire  the  Shares,  ADC has relied  upon
consultations with ADC's legal,  financial and tax advisers with respect to this
transaction  and the  nature  of the  investment  together  with the  additional
information concerning ProMedCo provided under subsection (a) above.

                (c) The financial condition of ADC is such that ADC can bear the
risk  of  this  investment  indefinitely.   ADC,  either  alone  or  with  ADC's
representatives  has such  knowledge  and  experience  in financial and business
matters that ADC is capable of evaluating  the merits and risks of an investment
in ProMedCo.

                (d) ADC wil-I not transfer or otherwise dispose of the Shares or
any interest therein, except in accordance with the Stockholder Agreement and in
such manner as to not violate any  registration  provision of the Securities Act
of  1933,  as  amended  (the  "Securities  Act"),  or of  any  applicable  state
securities law regulating the disposition  thereof.  Except for the shares to be
registered under Section 2.1(a) of this Agreement,  ADC is aware that the Shares
have not been registered  under the Securities Act or any state  securities laws
or any other applicable securities  legislation and that the Shares must be held
indefinitely  unless they are subsequently  registered or an exemption from such
registration  is available.  ProMedCo will permit  transfer of the Shares by ADC
only when such  securities  have been  registered  under the Securities Act, any
applicable state securities law and any other applicable securities  legislation
or when the  request is  accompanied  by an opinion of  counsel,  acceptable  to
ProMedCo,  to the effect  that the sale or  proposed  transfer  does not require
registration  under the  Securities  Act, any state  securities law or any other
applicable  securities  legislation,  or when presented with evidence  otherwise
satisfactory  to ProMedCo.  ADC agrees that the following  legend to such effect
and any other legends required by applicable state securities law will be placed
on the  unregistered  Shares  and a stop  transfer  order  shall be placed  with
respect thereto, for as long as ProMedCo deems it necessary:

"The shares  represented by this  certificate have not been registered under the
Securities  Act of 1933 as amended,  or any state  securities  laws (Acts).  The
shares have been acquired for investment and may not be sold or offered for sale
in the absence of an effective  registration  statement for the shares under the
Acts or an opinion of counsel or other  evidence  satisfactory  to ProMedCo that
such registration is not required."

                (e)  ADC   acknowledges   that  ADC  has  not   relied   on  any
representation by any person,  whether such  representation was made directly or
indirectly,  regarding  the amount,  percentage  or type of profit or loss to be
realized,  if any, from an investment  in the Shares.  ADC further  acknowledges
that the prior  experience  of ProMedCo or any other  person is not in any way a
prediction of the results which ADC may obtain as a result of its  investment in
the Shares.  ADC further  acknowledges that ADC is familiar with the business to
be  conducted  by the  ProMedCo  and has had full  access to the  business  plan
formulated by the ProMedCo.

                (f)  The  representations,   warranties  and  covenants  of  ADC
contained  herein shall survive the execution and delivery of this Agreement and
the issuance of the Shares.

Parties may defend  against such claim or litigation in such manner as they deem
appropriate.  The  Indemnifying  Party shall,  in accordance with the provisions
hereof,  promptly  reimburse  th6  Indemnified  Parties  for the  amount  of any

6.       FACILITIES TO BE PROVEDED BY PROMEDCO

         6.1  Facilities.  ProMedCo  hereby  agrees to  provide  or arrange as a

professional, and ethical aspects of its medical practice. If a Physician Member
or a Physician Employee performs abortion  procedures in any facility,  ProMedCo
shall not receive any ProMedCo Distribution from the revenue generated from such
procedures.

set forth  herein is being paid to ProMedCo in  consideration  of a  substantial
commitment  made  by  ProMedCo  hereunder  and  that  such  fees  are  fair  and
reasonable. Upon execution of this Agreement, but in no event not later than the
Effective  Date of this  Agreement,  ADC will pay  ProMedCo  an  estimate of the
monthly amount of all Clinic Expenses paid


<PAGE>

Date of this Agreement  ProMedCo shall be paid the amount of all Clinic Expenses
and the ProMedCo Distribution.

         7.2 Clinic Expenses.  Commencing on the Effective Date,  ProMedCo shall
pay all Clinic Expenses as they fall due, provided,  however, that ProMedCo may,
in the name of and on behalf of ADC,  contest in good faith any  claimed  Clinic
Expenses as to which there is any dispute  regarding  the nature,  existence  or
validity of such claimed Clinic  Expenses.  ProMedCo  hereby agrees to indemnify
and hold ADC harmless from and against any  liability,  loss,  damages,  claims,
causes of action and  reasonable  expenses of ADC resulting  from the contest of
any Clinic Expenses.  Any Clinic Expenses  incurred and not paid by ADC prior to

to ProMedCo by ADC within 30 days of payment by ProMedCo.

Clinic  Expense,  all  necessary  insurance,  including,  but  not  limited  to,
comprehensive professional liability insurance for all professional employees of
ProMedCo  and ADC with  limits  as  determined  reasonable  by  ProMedCo  in its
national  program,   comprehensive  general  liability  insurance  and  property
insurance covering the Clinic Facility and operations.

professional liability insurance with limits of not less than $300,000 per claim
and with  aggregate  policy limits of not less than $600,000 per physician and a
separate limit for ADC. ADC shall be responsible for all liabilities  (including
without  limitation  deductibles  and excess  liabilities)  not paid  within the
limits of such  policies.  ProMedCo  shall have the option,  with Policy Council
approval,  of  providing  such  professional   liability  insurance  through  an
alternative  program,  provided  such  program  meets  the  requirements  of the
Insurance Commissioner of the State of Texas.

         8.3  Tail  Insurance  Coverage.   Unless  covered  by  an  "occurrence"
malpractice policy, ADC will cause each individual physician associated with the
Clinic  to  enter  into an  agreement  with ADC that  upon  termination  of such
physician's  relationship with ADC, for any reason, tail insurance coverage will
be purchased by the individual  physician.  Such  provisions may be contained in
employment  agreements,  restrictive  covenant  agreements  or other  agreements
entered into by ADC and the individual physicians, and ADC hereby covenants with
ProMedCo to enforce such provisions  relating to the tail insurance  coverage or
to provide such


<PAGE>



cover-age at the expense of ADC.

         8.4      Additional Insured.  ADC and ProMedCo agree to use their best
efforts to have each other named as an additional insured on the other's

ProMedCo,  its officers,  directors and employees,  from and against any and all
liability,  loss,  damage,  claim,  causes of action,  and  expenses  (including
reasonable  attorneys' fees), to the extent not covered by insurance,  caused or
asserted to have been caused,  directly or indirectly,  by or as a result of (i)
the performance of medical services or any other acts or omissions by ADC and/or
its members,  agents,  employees  and/or  subcontractors  (other than  ProMedCo)
during the term hereof, including any claim against ProMedCo by an ADC Employee,
which claim arises out of such ADC Employees'  employment  relationship with ADC
or as a result of services performed by such ADC Employee, and which claim would
typically  be  covered by  worker's  compensation  and (ii) any  claims  made by
Hospitals  against  ProMedCo  because  of  ProMedCo's   entering  into  and  its
performance of the terms and conditions of this  Agreement,  including,  but not
limited to, any and all liability,  loss, damage,  claim,  causes of action, and
expenses  (including  reasonable  attorneys'  fees)  for  alleged  breach  of or
tortious  interference with the Hospital  Agreements.  ProMedCo shall indemnify,
hold harmless and defend ADC, its officers,  directors and  employees,  from and
against  any and all  liability,  loss,  damage,  claim,  causes of action,  and
expenses  (including  reasonable  attorneys' fees), to the extent not covered by
insurance, 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  ProMedCo   and/or  its   members,   agents,   employees   and/or
subcontractors  (other than ADC) during the term of this  Agreement,  except for
any liability,  loss, damage,  claim, causes of action, and expenses which might
arise in connection with the Hospital Agreements.

9. RESTRICTIVE COVENANTS AND LIQUIDATED DAMAGES

         The  parties  recognize  that the  services  to be provided by ProMedCo
shall be feasible only if ADC operates an active  medical  practice to which the
physicians  associated  with ADC devote their full time and  attention.  To that
end:

         9.1  Restrictive  Covenants by ADC.  During the term of this Agreement,
ADC shall not establish,  operate or provide  physician  services at any medical
office,  clinic or other health care facility providing  services  substantially
similar to those  provided by ADC pursuant to this Agreement  anywhere  within a
radius of  twenty-five  (25) miles of the Taylor  County  Courthouse in Abilene,
Texas,  or within a radius of  twenty-five  (25) miles of any  current or future
medical  office,  clinic or other health care  facility  from which ADC provides
medical services.

         9.2      Restrictive Covenants By Current Physician Members and
Physician Employees. ADC shall enforce the employment agreements with its
current Physician Members and Physician Employees in a form satisfactory
to ProMedCo, pursuant to which the Physician Members and Physician


<PAGE>



Employees agree not to establish,  operate or provide physician  services at any
medical office,  clinic or outpatient and/or ambulatory  treatment or diagnostic
facility  providing  services  substantially  similar to those  provided  by ADC
pursuant  to this  Agreement  within a radius of  twenty-five  (25) miles of the
Taylor County  Courthouse in Abilene,  Texas,  or within a radius of twenty-five
(25) miles of any current or future medical office,  clinic or other health care
facility  from  which  ADC  provides  medical  services,  and  for a  period  of
thirty-six (36) months after the first date of such Physician  Shareholder's  or
such Physician  Employee's  employment with ADC. ProMedCo shall have third-party
rights to enforce such agreements.

         9.3  Restrictive  Covenants By Future  Physician  Employees.  ADC shall
obtain  and  enforce  formal  employment  agreements  from  each  of its  future
Physician  Members and Physician  Employees in a form  satisfactory to ProMedCo,
pursuant to which such  physicians  agree not to  establish,  operate or provide
physician services at any medical office, clinic or outpatient and/or ambulatory
treatment or diagnostic  facility  providing services  substantially  similar to
those provided by ADC pursuant to this Agreement  within a radius of twenty-five
(25) miles of the Taylor County Courthouse in Abilene, Texas, or within a radius
of  twenty-five  (25) miles of any current or future medical  office,  clinic or
other health care facility from which ADC provides  medical  services during the
term of said  Physician  Employee's  employment  with  ADC and for a  period  of
thirty-six  (36)  months  after  the date of their  first  employment  with ADC.
ProMedCo shall have third-party rights to enforce such agreements.

         9.4 Physician  Shareholder and Physician Employee  Liquidated  Damages.
The  restrictive  covenants  described in Sections 9.2 and 9.3 of this Agreement
shall provide that the Physician  Members and Physician  Employees  (existing or
future) may be released from their  restrictive  covenants by paying  Liquidated
Damages in the amount of Two  Hundred  Thousand  Dollars  ($200,000.00)  or such
physician's  income from the practice of  medicine,  as reported to the Internal
Revenue  Service for the  previous  twelve (12) months,  whichever is less.  The
accounting treatment of such funds shall be consistently applied and approved by
ProMedCo's independent certified public accountants and the Policy Council.

         9.5  Enforcement.  ProMedCo and ADC  acknowledge and agree that since a
remedy at law for any  breach or  attempted  breach  of the  provisions  of this
Section 9 shall be  inadequate,  either  party  shall be  entitled  to  specific
performance and injunctive or other equitable  relief in case of any such breach
or attempted  breach,  in addition to whatever  other remedies may exist by law.
All parties hereto also waive 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 Section 9 relating to 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  deemed to be reasonable  and
enforceable by the court shall thereafter be the time period, scope of activity,
restricted  and/or area of restriction  applicable to the  restrictive  covenant
provisions  in this  Section 9. The  invalidity  of  non-enforceability  of this
Section 9 in any respect shall


<PAGE>



not affect the validity of  enforceability of the remainder of this Section 9 or
of any other provisions of this Agreement unless the invalid or  non-enforceable
provisions  materially  affect the  benefits  either  party would  otherwise  be
entitled  to  receive  under  this  Section  9 or any  other  provision  of this
Agreement.

         9.6 Termination of Restrictive Covenants.  Notwithstanding  anything to
the contrary  contained herein,  if this Agreement is terminated,  the rights of
ProMedCo under these restrictive  covenants contained in this Section 9 shall be
null and void and of no force or effect.

from the Account not authorized by the express terms of this  Agreement,  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  ProMedCo,  in addition to any other remedies that it
may  have  at law or in  equity,  to  seek a  court  ordered  assignment  of the

reasonable time during business hours.

         5.3  Access  to  Records.  During  the  term  of  this  Agreement,  and

obligations under this Agreement, and ADC may copy any or all such records.

6.  FACILITIES TO BE PROVIDED BY PROMEDCO

         6.1  Facilities.  ProMedCo hereby agrees to provide or arrange as a 
Clinic Expense the offices and facilities for Clinic operations, including but

<PAGE>



improvements,   utility  (telephone,  electric,  gas,  water)  expenses,  normal
janitorial  services,  related real or personal property lease cost payments and
expenses, taxes and insurance,  refuse disposal and all other costs and expenses
reasonable  incurred in conducting  operations in the Clinic Facility during the
term of this Agreement.

         6.2 Use of  Facilities.  Voluntary  abortions  will not be performed in
facilities  that are owned or leased by  ProMedCo  or any of its  affiliates  in
whole or in part. ProMedCo and ADC agree that ADC, as an independent contractor,
is a separate  organization  that  retains the  authority to direct the medical,
professional, and ethical aspects of its medical practice. If a Physician Member
or a Physician Employee performs abortion  procedures in any facility,  ProMedCo
shall not receive any ProMedCo Distribution from the revenue generated from such
procedures.

7.  FINANCIAL ARRANGEMENTS

         7.1  Payments  to ADC and  ProMedCo.  ADC and  ProMedCo  agree that the
compensation  set forth herein is being paid to ProMedCo in  consideration  of a
substantial  commitment  made by ProMedCo  hereunder and that such fees are fair
and reasonable. As payment for its services rendered to ADC, each month ProMedCo
shall be paid the amount of all Clinic  Expenses and the ProMedCo  Distribution.
All Net Clinic  Revenues after  deduction of Clinic  Expenses,  and the ProMedCo
Distribution, shall be referred to as the "ADC Distribution. "


         7.2  Calculation  of Payments.  ProMedCo shall pay to ADC in accordance
with the provisions of Section 7.4 the ADC Distribution  amounts on or about the
15th day of such following  month.  Some amounts may need to be estimated,  with
Adjustments made as necessary the following month. Any audit  Adjustments  would
be made after completion of the fiscal year audit.

         7.3 Clinic Expenses.  Commencing on the Effective Date,  ProMedCo shall
pay all Clinic Expenses as they fall due, provided,  however, that ProMedCo may,
in the name of and on behalf of ADC,  contest in good faith any  claimed  Clinic
Expenses as to which there is any dispute  regarding  the nature,  existence  or
validity of such claimed Clinic  Expenses.  ProMedCo  hereby agrees to indemnify
and hold ADC harmless from and against any  liability,  loss,  damages,  claims,
causes of action and  reasonable  expenses of ADC resulting  from the contest of
any Clinic Expenses.

         7.4 Accounts Receivables. Except for the first month of this Agreement,
on  approximately  the 15th  day of each  month,  ProMedCo  shall  purchase  the
accounts  receivable  of ADC arising  during the previous  month,  by payment of
cash, or other readily available funds into an account of ADC. The consideration
for the  purchase  shall be an  amount  equal to actual  charges  of ADC for the
previous month, less  Adjustments.  The Purchase Amount shall be further reduced
by the amount due to ProMedCo  for the  previous  month's  Clinic  Expenses  and
ProMedCo Distribution and such reduction shall serve as payment for such month's
Clinic Expenses and ProMedCo  Distribution as provided for in Section 7.1 above.
Although it is the intention of the parties that  ProMedCo  purchase and thereby
become owner of the accounts  receivable of ADC, in case such purchase  shall be
ineffective  for any reason,  ADC, as of the Effective  Date of this  Agreement,
grants and shall cause each ADC  Employee to grant to ProMedCo a first  priority
lien on and security interest in and to any and all interest of ADC and such ADC
Employees in any accounts  receivable  generated by the medical  practice of ADC
and the ADC  Employees  or otherwise  generated  through the  operations  of the
Clinic, and all proceeds with respect thereto, to secure the payment to ProMedCo
of all such  accounts  receivable,  and this  Agreement  shall be deemed to be a
security  agreement to the extent necessary to give effect to the foregoing.  In
addition,  ADC shall cooperate with ProMedCo and execute and deliver,  and cause
each ADC Employee to execute and deliver,  all necessary documents in connection
with the pledge of such accounts receivable to ProMedCo or at ProMedCo's option,
its lenders.  All  collections in respect of such accounts  receivable  shall be
deposited in a bank account at a bank designated by ProMedCo. To the extent ADC


<PAGE>



or any ADC  Employee  comes into  possession  of any payments in respect of such
accounts  receivable,  ADC or such ADC Employee  shall  direct such  payments to
ProMedCo for deposit in bank accounts designated by ProMedCo.


8.       INSURANCE AND INDEMNITY

         8.1 Insurance to Be Maintained by ProMedCo. Throughout the term of this
Agreement,  ProMedCo will use reasonable  efforts to provide and maintain,  as a
Clinic  Expense,  all  necessary  insurance,   including,  but  not  limited  to
comprehensive professional liability insurance for all professional employees of
ProMedCo  and ADC with  limits  as  determined  reasonable  by  ProMedCo  in its
national  program,   comprehensive  general  liability  insurance  and  property
insurance covering the Clinic Facility and operations.

professional liability insurance with limits of not less than $300,000 per claim
and with  aggregate  policy limits of not less than $600,000 per physician and a
separate limit for ADC. ADC shall be responsible for all liabilities  (including
without  limitation  deductibles  and excess  liabilities)  not paid  within the
limits of such  policies.  ProMedCo  shall have the option,  with Policy Council
approval,  of  providing  such  professional   liability  insurance  through  an
alternative  program,  provided  such  program  meets  the  requirements  of the
Insurance Commissioner of the State of Texas.

         8.3  Tail  Insurance  Coverage.   Unless  covered  by  an  "occurrence"
malpractice policy, ADC will cause each individual physician associated with the
Clinic  to  enter  into an  agreement  with ADC that  upon  termination  of such
physician's  relationship with ADC, for any reason, tail insurance coverage will
be purchased by the individual  physician.  Such  provisions may be contained in
employment  agreements,  restrictive  covenant  agreements  or other  agreements
entered into by ADC and the individual physicians, and ADC hereby covenants with
ProMedCo to enforce such provisions  relating to the tail insurance  coverage or
to provide such coverage at the expense of ADC.

         8.4  Additional  Insured.  ADC and  ProMedCo  agree to use  their  best
efforts  to have  each  other  named as an  additional  insured  on the  other's
respective professional liability insurance programs at ProMedCo's expense.

         8.5  Indemnification.  ADC shall  indemnify,  hold  harmless and defend
ProMedCo,  its officers,  directors and employees,  from and against any and all
liability,  loss,  damage,  claim,  causes of action,  and  expenses  (including
reasonable  attorneys' fees), to the extent not covered by insurance,  caused or
asserted to have been caused,  directly or indirectly,  by or as a result of (i)
the performance of medical services or any other acts or omissions by ADC and/or
its Members,  agents,  employees  and/or  subcontractors  (other than  ProMedCo)
during the term hereof, including any claim against ProMedCo by an ADC Employee,
which claim arises out of such ADC Employees'  employment  relationship with ADC
or as a result of services performed by such ADC Employee, and which claim would
typically  be  covered by  worker's  compensation  and (ii) any  claims  made by
Hospitals  against  ProMedCo  because  of  ProMedCo's   entering  into  and  its
performance of the terms and conditions of this  Agreement,  including,  but not
limited to, any and all liability,  loss, damage,  claim,  causes of action, and
expenses  (including  reasonable  attorneys'  fees)  for  alleged  breach  of or
tortious  interference with the Hospital  Agreements.  ProMedCo shall indemnify,
hold harmless and defend ADC, its officers,  directors and  employees,  from and
against  any and all  liability,  loss,  damage,  claim,  causes of action,  and
expenses  (including  reasonable  attorneys' fees), to the extent not covered by
insurance, 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  ProMedCo   and/or  its   Members,   agents,   employees   and/or
subcontractors  (other than ADC) during the term of this  Agreement,  except for
any liability,  loss, damage,  claim, causes of action, and expenses which might
arise in connection with the

Hospital Agreements.

9. RESTRICTIVE COVENANTS AND LIQUIDATED DAMAGES

         The  parties  recognize  that the  services  to be provided by ProMedCo
shall be feasible only if ADC operates an active  medical  practice to which the
physicians  associated  with ADC devote their full time and  attention.  To that
end:

         9.1  Restrictive  Covenants by ADC.  During the term of this Agreement,
ADC shall not,  outside  the  Clinic,  establish,  operate or provide  physician
services at any medical office,  clinic or other health care facility  providing
services  substantially  similar  to  those  provided  by ADC  pursuant  to this
Agreement  anywhere  within a radius of  twenty-five  (25)  miles of the  Taylor
County  Courthouse in Abilene,  Texas,  or within a radius of  twenty-five  (25)
miles of any  current or future  medical  office,  clinic or other  health  care
facility from which ADC provides medical services.

         9.2 Restrictive  Covenants By Current  Physician  Members and Physician
Employees.  ADC  shall  enforce  the  employment  agreements  with  its  current
Physician  Members and Physician  Employees in a form  satisfactory to ProMedCo,
pursuant to which the  Physician  Members and Physician  Employees  agree not to
establish,  operate or provide physician services at any medical office,  clinic
or  outpatient  and/or  ambulatory  treatment or diagnostic  facility  providing
services  substantially  similar  to  those  provided  by ADC  pursuant  to this
Agreement  within a radius  of  twenty-five  (25)  miles  of the  Taylor  County
Courthouse in Abilene,  Texas,  or within a radius of twenty-five  (25) miles of
any current or future medical office,  clinic or other health care facility from
which ADC provides medical services,  and for a period of thirty-six (36) months
after  the  first  date  of  such  Physician  Shareholder's  or  such  Physician
Employee's  employment  with ADC.  ProMedCo  shall  have  third-party  rights to
enforce such agreements.

         9.3  Restrictive  Covenants By Future  Physician  Employees.  ADC shall
obtain  and  enforce  formal  employment  agreements  from  each  of its  future
Physician  Members and Physician  Employees in a form  satisfactory to ProMedCo,
pursuant to which such  physicians  agree not to  establish,  operate or provide
physician services at any medical office, clinic or outpatient and/or ambulatory
treatment or diagnostic  facility  providing services  substantially  similar to
those provided by ADC pursuant to this Agreement  within a radius of twenty-five
(25) miles of the Taylor County Courthouse in Abilene, Texas, or within a radius
of  twenty-five  (25) miles of any current or future medical  office,  clinic or
other health care facility from which ADC provides  medical  services during the
term of said  Physician  Employee's  employment  with  ADC and for a  period  of
thirty-six  (36)  months  after  the date of their  first  employment  with ADC.
ProMedCo shall have third-party rights to enforce such agreements.

         9.4 Physician  Shareholder and Physician Employee  Liquidated  Damages.
The  restrictive  covenants  described in Sections 9.2 and 9.3 of this Agreement
will provide that the  Physician  Members and Physician  Employees  (existing or
future) may be released from their  restrictive  covenants by paying  Liquidated
Damages in the amount of Two  Hundred  Thousand  Dollars  ($200,000.00)  or such
physician's  income from the practice of  medicine,  as reported to the Internal
Revenue  Service for the previous  twelve (12) months,  whichever is less.  Such
payment shall be made to ProMedCo by ADC simultaneously  with the payment by the
physician to ADC. Such payment  shall be first applied to all costs  incurred by
ProMedCo in the  enforcement  of the  restrictive  covenant  for that  departing
physician  and  in  recruiting  a  replacement   physician  for  that  departing
physician.  The remainder,  if any, shall become an additional service fee to be
paid to ProMedCo  pursuant to Section 7. The accounting  treatment of such funds
shall be consistently applied and approved by ProMedCo's  independent  certified
public accountants and the Policy Council.

         9.5  Enforcement.  ProMedCo and ADC  acknowledge and agree that since a
remedy at law for any  breach or  attempted  breach  of the  provisions  of this
Section 9 shall be inadequate, either party shall be entitled to specific


<PAGE>



performance and injunctive or other equitable  relief in case of any such breach
or attempted  breach,  in addition to whatever  other remedies may exist by law.
All parties hereto also waive 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 Section 9 relating to 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  deemed to be reasonable  and
enforceable by the court shall thereafter be the time period, scope of activity,
restricted  and/or area of restriction  applicable to the  restrictive  covenant
provisions  in this  Section 9. The  invalidity  of  non-enforceability  of this
Section 9 in any respect shall not affect the validity of  enforceability of the
remainder of this Section 9 or of any other  provisions of this Agreement unless
the invalid or non-enforceable  provisions materially affect the benefits either
party would  otherwise be entitled to receive  under this Section 9 or any other
provision of this Agreement.

         9.6 Termination of Restrictive Covenants.  Notwithstanding  anything to
the contrary  contained  herein,  if this  Agreement is  terminated  pursuant to
Section 10.2 herein, the restrictive covenants contained in this Section 9 shall
be null and void and of no force or effect.

remedies  herein  granted to the  aggrieved  party  shall be  cumulative  and in

14. TERMINATION OF EMPLOYMENT - The employee's employment under the Agreement,
shall be terminated immediately upon the happening of any of the following

<PAGE>




(a) The termination by the Employer of the Employee's employment without cause
upon at least ninety (90) days written notice to the Employee; provided,

cause pursuant to Paragraph 14(a) or 14(b), the Employer, at its option, may
require the Employee to cease providing services to the Employer immediately;
provided, however, that the Employee shall receive his compensation and other
benefits, if any, hereunder until the effective date of such termination.

15.      PAYMENTS BY EMPLOYER UPON TERMINATION. Within fifty (50) days
following the effective date of the Employee's termination of


<PAGE>



employment (the "Termination Date"), the Employer shall pay the Employee (or his
legal representative, as the case may be) his compensation due under Paragraph 8
above prorated through the Termination Date. Except as provided in this
Paragraph, the Employee shall not be entitled to receive any severance pay or
other compensation. The Employee shall not have nor acquire any interest in the
Employer's accounts receivable, shall not be entitled to receive any payment
from or on account of such accounts receivable and shall have no interest in or
claim to the nonvested portion of his benefits in any qualified retirement plan
maintained by the Employer.

16.      PAYMENTS BY EMPLOYEE UPON TERMINATION.  Upon the termination
of the Employee's employment, the Employee (or his legal
representative, as the case may be) shall pay the Employer an
amount equal to the sum of:

(a)  all amounts owed by the Employee to the Employer as of the
Termination Date; and

(b) the value of all prepaid and unearned items and expenses paid by the
Employer for the benefit of the Employee including, without limitation, all
prepaid and unearned premiums for health insurance prorated through the
Termination Date but only to the extent the Employee continues to derive
benefits from such coverage after the Termination Date.

The amount payable to the Employer pursuant to this Paragraph shall be
determined by the accountant retained by the Employer and such determination,
when made and delivered to the Employer and the Employee (or his legal
representative, as the case may be), shall be conclusive and binding on the
Employer and the Employee (or his legal representative, as the case may be) -
The Employer may offset any amounts payable to it pursuant to this Paragraph
against any amounts payable by the Employer to the Employee (or his legal
representative, as the case may be) under this Agreement.

17.      DISABILITY.

(a) Amount. Notwithstanding anything to the contrary herein, in the event the
Employee becomes totally disabled, as defined below, and is unable to perform
his normal duties as an employee of the Employer, then the Employee, in lieu of
any compensation due under Paragraph 8 above, shall pay Employee only such
compensation as the Board may approve. The parties acknowledge that Employee's
compensation and disability benefits hereunder shall be based on Employee's
productivity and that Employee's disability will likely result in a reduction
and possible elimination of Employee's compensation hereunder.

(b) Termination of Employment. In the event such total disability continues for
a period of (_) months in a month period, such disability shall be deemed to be
permanent total disability, and the Employee's employment hereunder shall, at
the end of such (_)


<PAGE>



month period, be automatically terminated. If, however, prior to the end of such
(_) month period of total disability, the Employee's total disability shall have
ceased and he shall have resumed the performance of his normal duties hereunder,
the Employee shall thereafter receive his full compensation as set forth in
Paragraph 8 hereof.

(c) Definition and Determination of Total Disability. For purposes of this
Agreement, the term "total disability" shall mean the Employee's inability to
perform the normal duties of his employment by the Employer as a physician. If
there is any disagreement between the Employer and the Employee as to the
disability or non-disability of the Employee or as to the effective date of any
such disability, the same shall be determined after an examination of the
Employee by a physician to be selected by the Board and ProMedCo. The Employee
shall be available for such an examination at any reasonable time. The
determination of such physician selected by the Employer shall be conclusive
evidence of the disability or the nondisability of the Employee and of the date
any such disability began. If the Employee should not cooperate in the
examination by such physician selected by the Employer, then, for purposes
hereof, the determination of the Employee's disability or nondisability and the
date any such disability began shall be made by the Employer and ProMedCo in
their sole discretion.

18. PROFESSIONAL LIABILITY INSURANCE. The Employer, at its expense shall carry
professional liability (malpractice) insurance for the Employee in the same
manner, with the same limitations and to the same extent and amount, if any, as
is provided by the Employer for its other professional employees. Upon the
termination of his employment, the Employee shall pay the "tail premium," "final
endorsement premium" or any other premium or charge for extending the coverage
of the professional liability insurance then carried by the Employer for the
nine (9) year period beginning on the date of such termination or otherwise
cause such insurance to remain in effect for such nine (9) year period. if the
Employee fails to pay such tail premium or cause such insurance to remain in
effect for such nine (9) year period, the Employer may pay such tail premium and
the Employee shall reimburse the Employer for any and all costs incurred by the
Employer in connection with the Employer's payment of such tail premium
including interest on such amount at a rate of 15% per annum. Any premium refund
or similar reimbursement which may be payable by any malpractice insurance
company upon the cancellation of the Employee's coverage on account of the
termination of his employment with the Employer shall be the exclusive property
of the Employer and the Employee shall cooperate in good faith with the
Employer's efforts to collect any such amounts.

19.      PROMEDCO CONSIDERATION.  In the event that, during the Initial
Term of this Agreement, the Employee is terminated by Employer
pursuant to Paragraphs 14(c), (e), (f), (h), (i) or (j), or by the
Employee pursuant to Paragraph 14(b), the Employee shall forfeit
any Unredeemed Equity (as defined in the Service Agreement) that


<PAGE>



was yet to be received by him pursuant to the Stock Purchase Agreement (this
would include any future interest or principal payments under the Convertible
Subordinated Note, and any future Converted Shares) attributable to the sale of
his shares in CFP, Inc. Said future consideration will be transferred to
ProMedCo (the "Transfer"). The Employee acknowledges that in the event that,
during the Initial Term, Employee is terminated by Employer pursuant to
Paragraph 14(c), (e), (f), (h), (i) or (j) or the Employee's termination of his
or her employment pursuant to Paragraph 14(b), it would be difficult to
calculate the precise amount of damages and for that reason the parties have
determined that the Transfer will be appropriate liquidated damages for such
actions during the Initial Term hereof. The Transfer shall be effective as of
the date of the event giving rise to the termination of Employee's employment
hereunder by Employer or Employee as aforesaid. The Employee hereby appoints
ProMedCo as its attorney in fact to cause such Transfer. The Employer and
ProMedCo shall be entitled to specific performance and other equitable relief to
enforce the Transfer. This provision is in addition to the rights of Employer
pursuant to Paragraph 14 of this Agreement.

20.      NON-COMPETITION AND NON-SOLICITATION.

(a) Noncompetition. During the term of his employment hereunder (including any
extensions thereof), the Employee shall not, either directly as a partner,
employer, agent, independent contractor, employee or indirectly through a
corporation, partnership, affiliate, subsidiary or otherwise:

(1) establish, operate or provide professional medical services at any medical
office, clinic or outpatient and/or ambulatory treatment or diagnostic facility
within the geographic area described in Exhibit A attached hereto (the "Area")
other than such offices, clinics or facilities owned, operated, managed, staffed
or leased by ProMedCo, or any affiliate thereof;

(2) solicit, induce or attempt to induce, in connection with any business
competitive with that of the Employer, patients of any physician associated with
the Employer to leave the care of physicians associated with the Employer; or

(3) solicit, induce or attempt to induce any employee, consultant or other
persons associated with the Employer or ProMedco to leave the employment of, or
to discontinue their association with the Employer or ProMedCo, or any affiliate
thereof.

(b) Employee agrees and covenants that for a period of twenty-four (24) months
after the date of termination of his employment with CPC during the Initial
Term, the Employee shall not, either directly as a partner, employer, agent,
independent contractor, employee or indirectly through a corporation,
partnership, affiliate, subsidiary or otherwise, (a) enter into a provider
agreement or other contract with, nor provide any medical services


<PAGE>



in connection with or pursuant to any such provider agreement or other contract,
any third party payor having a provider agreement or other contract with CPC or
any other employee of CPC at any time within 120 days prior to and including the
date of Employee's termination of employment with CPC or (b) solicit, induce or
attempt to induce any patient of CPC to become a patient of Employee or any
partner, employee or affiliate of Employee. As used herein, a third party payor
shall include, without limitation, any employer, coalition of employers, union
or similar organization maintaining a health benefit plan for the benefit of its
employees or members, any insurance company, any Blue Cross/Blue Shield plan,
any health maintenance organization, preferred provider organization,
independent physicians association, physicians hospital organization, or similar
entity or arrangement which contracts for physician services on behalf of its
employees or members or other third party payors. However, as used herein, the
term "third party payor" shall not include the federal Medicare program or the
state Medicaid program, although such terms shall include any health maintenance
organization providing Medicare or Medicaid benefits to plan participants. This
provision shall be limited in its application to the Area.

(c) Covenants Necessary. The covenants contained in Paragraphs 20 and 22 herein
are necessary to protect the business and goodwill of the Employer and ProMedCo
and a breach of these covenants will result in the irreparable harm and
continuing damage to the Employer and ProMedCo. In the event the Employee
breaches such covenants during the Initial Term, the Employer and ProMedCo shall
be entitled to specific performance and/or injunctive or other equitable relief
in order to prevent the continuation of such harm, as well as money damages. The
Employee waives any requirement for the securing or posting of any bond in
connection with the obtaining of any such equitable relief. The Employee
acknowledges that if the Employee breaches the covenants contained in Paragraph
20(b) and the Employer or ProMedCo is unable for any reason to obtain a
restraining order from a court of competent jurisdiction within thirty (30) days
after application enjoining the breach by the Employee, it will be difficult to
calculate the precise amount of the Employer's damages. As a result, the parties
have determined that, in the event of such a breach, the Employer's damages
shall be equal to Liquidated Damages in the amount of the physician's total
compensation for the most recent 12 month period, but not in excess of $200,000.

(d) Limitations. The parties have attempted to limit the provisions of this
Paragraph 20 only to the extent necessary to protect each parties' interest. In
the event that any provision, section or subsection of this Paragraph 20 is
adjudged by any court of competent jurisdiction to be void or unenforceable, in
whole or part, such court shall modify and enforce any such provision, section,
or subsection to the extent and geographic area that it believes to be
reasonable under the circumstances.

         Service Agreement  ("Agreement")  dated April 1, 1996, between ProMedCo
of Mayfield,  Inc., a Kentucky corporation ("ProMedCo") which is an affiliate of
ProMedCo,  Inc., a Texas  corporation  ("Parent") and  Morgan-Haugh,  P.S.C.,  a
Kentucky professional corporation ("MH").

RECITALS:

         MH is a multi-specialty medical practice in Mayfield,  Kentucky,  which
provides  professional  medical care to the general  public.  ProMedCo is in the
business of owning  certain  assets of and  managing and  administering  medical
clinics,  and  providing  non-professional  support  services to and  furnishing
medical practices with the necessary facilities,  equipment, personnel, supplies
and support staff. Pursuant to an Asset Purchase Agreement dated as of April 25,
1996, between ProMedCo, Inc. and MH ("Asset Purchase Agreement") ProMedCo agreed
to assume certain  liabilities and purchase certain assets used in the operation
of the medical practice to be conducted by MH.

         Subject  to the terms  and  conditions  hereof,  MH  desires  to engage
ProMedCo to provide to MH management services, facilities,  personnel, equipment
and supplies  necessary  to operate the Clinic (as defined  herein) and ProMedCo
desires to accept such engagement.

         The parties agree as follows:

1.  RESPONSIBILITIES OF THE PARTIES

         1.1 General Responsibilities of the Parties.  ProMedCo shall provide MH
with  offices,  facilities,   equipment,   supplies,   non-professional  support
personnel,   and  management  and  financial  advisory  services.  MH  shall  be
responsible for the recruitment  and hiring of physicians,  Technical  Employees
and all issues related to patient care and documentation thereof. ProMedCo shall
neither  exercise   control  over  nor  interfere  with  the   physician-patient
relationship,  which shall be maintained  strictly  between the physicians of MH
and their patients.

         1.2 MH's Matters.  MH shall maintain sole discretion and authority over
the  financial  matters  relative  to its  corporate  existence.  It  shall  set
compensation levels for MH Employees.  MH will also be responsible for all other
matters pertaining to the operation of MH.

         1.3 Patient Referrals. The parties agree that the benefits to MH do not
require,  are not  payment  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  ProMedCo  to any of  MH's  patients  in  any  facility  or
laboratory controlled, managed or operated by ProMedCo.

2.  POLICY COUNCIL

         2.1  Formation and Operation of the Policy  Council.  A Policy  Council

serve as the basis for  operations  of the  Clinic.  The  Policy  Council  shall
consist of four members. ProMedCo shall designate, at its sole

discretion,  two members of the Policy  Council.  Members of the Policy  Council
designated  by  ProMedCo  shall be  entitled  to attend and vote by proxy at any
meetings of the Policy  Council so long as at least one such  representative  is
present in person. MH at its sole discretion shall designate two members. Except

Council shall be the act of the Policy Council.

         2.2 Duties and Responsibilities of the Policy Council.  During the term

expertise,  shall be subject to the review and  approval of the Policy  Council,
provided; however, ProMedCo shall have final approval of any capital expenditure
required by ProMedCo.

     (b)  Administrator.  The  selection  and  retention  of  the  Administrator
pursuant  to  Section  3.1 shall be subject to the  reasonable  approval  of the
Policy  Council.  If MH is  dissatisfied  with  the  services  provided  by  the
Administrator,  MH shall refer the matter to the Policy  Council.  ProMedCo  and
Policy  Council shall in good faith  determine  whether the  performance  of the
Administrator  could  be  brought  to  acceptable  levels  through  counsel  and
assistance,  or whether the Administrator  should be terminated.  ProMedCo shall
have the ultimate authority to terminate the Administrator.

     (c) Physician  Hiring.  The Policy Council,  with  information and analysis
provided by ProMedCo, shall determine the number and type of physicians required
for the efficient  operation of the Clinic and MH shall determine the individual
physicians to be hired to fill such positions. The approval of ProMedCo shall be
required  for any  variations  to the  restrictive  covenants  in any  physician
employment contract.

shall review and adopt the fee schedule for all physician and ancillary services
rendered by the Clinic.

ancillary  services  based  upon the  pricing,  access  to and  quality  of such
services.

     (f) Provider and Payor  Relationships.  The Policy  Council  shall make the

institutional  health care  providers  and payors.  The Policy  Council shall be
responsible  for approving the  allocation of capitation  risk pools between the
professional  and  institutional   components  of  these  pools  to  the  extent
applicable  under a payor  agreement.  ProMedCo and MH shall use actuarial  data
from a nationally  recognized  actuarial firm as agreed to by both parties,  for
the purposes of allocating  capitation  funds, for those  professional  services
provided directly by MH.

its services in whatever manner it deems reasonably  appropriate,  in accordance
with policies approved by the Policy Council,  and including without limitation,

                  3.1.3  Non-Physician  Personnel.  ProMedCo  will  provide  all
         personnel  reasonably  necessary  for the conduct of Clinic  operations

         segregate  Net Clinic  Revenues  from other funds of ProMedCo or MH. MH
         hereby  appoints  ProMedCo as its true and lawful  attorney-in-fact  to

         by ProMedCo  ("ProMedCo  Account").  MH and  ProMedCo  hereby  agree to
         execute from time to time such documents and  instructions  as shall be
         required by the bank  maintaining  the Account and mutually agreed upon
         to  effectuate  the  foregoing  provisions  and to extend or amend such
         documents and  instructions.  Any action by MH that interferes with the

Agreement,  grants and shall cause each MH Employee to grant to ProMedCo a first
priority lien on and security  interest in and to any and all interest of MH and

security  agreement to the extent necessary to give effect to the foregoing.  In
addition,  MH shall  cooperate with ProMedCo and execute and deliver,  and cause
each MH Employee to execute and deliver,  all necessary  documents in connection

accounts  receivable,  MH or such MH  Employee  shall  direct  such  payments to
ProMedCo for deposit in bank accounts designated by ProMedCo.

Council,  throughout  the term of this  Agreement,  subject to the provisions of
Section  4.5 and  Section  8.1,  MH shall  maintain  comprehensive  professional
liability  insurance with limits of not less than  $1,000,000 per claim and with
aggregate policy limits of not less than $3,000,000 per physician and a separate
limit for MH. MH shall be responsible  for all  liabilities  (including  without
limitation  deductibles  and excess  liabilities)  not paid within the limits of
such policies.  ProMedCo  shall have the option of providing  such  professional
liability insurance through an alternative program,  provided such program meets
the  requirements of the Insurance  Commissioner of the State of Kentucky and is
approved by the Policy Council.

         8.3 Tail Insurance  Coverage.  MH will cause each individual  physician
associated  with  the  Clinic  to  enter  into an  agreement  with MH that  upon
termination  of such  physician's  relationship  with MH, for any  reason,  tail
insurance  coverage  will  be  purchased  by  the  individual  physician.   Such
provisions  may be  contained in  employment  agreements,  restrictive  covenant
agreements or other agreements entered into by MH and the individual physicians,
and MH hereby covenants with ProMedCo to enforce such provisions relating to the
tail insurance coverage or to provide such coverage at the expense of MH.

         8.4 Additional Insured. MH and ProMedCo agree to use their best efforts
to have each other  named as an  additional  insured on the  other's  respective
professional liability insurance programs at ProMedCo's expense.

         8.5  Indemnification.  MH shall  indemnify,  hold  harmless  and defend
ProMedCo,  its officers,  directors and employees,  from and against any and all
liability,  loss,  damage,  claim,  causes of action,  and  expenses  (including
reasonable  attorneys' fees), to the extent not covered by insurance,  caused or
asserted to have been caused,  directly or indirectly,  by or as a result of (i)
the performance of medical  services or any other acts or omissions by MH and/or
its shareholders,  agents, employees and/or subcontractors (other than ProMedCo)
during the term hereof,  including any claim against  ProMedCo by a MH Employee,
which claim arises out of such MH Employees' employment  relationship with MH or
as a result of services  performed  by such MH  Employee,  and which claim would
typically be covered by worker's  compensation and (ii) ProMedCo's entering into
and its  performance  of the terms and  conditions of this  Agreement.  ProMedCo
shall  indemnify,  hold  harmless  and defend MH, its  officers,  directors  and
employees,  from and against any and all liability,  loss, damage, claim, causes
of action, and expenses  (including  reasonable  attorneys' fees), to the extent
not covered by  insurance,  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  ProMedCo  and/or  its  shareholders,  agents,
employees  and/or  subcontractors  (other  than  MH)  during  the  term  of this
Agreement.

9.   RESTRICTIVE COVENANTS AND LIQUIDATED DAMAGES

         The  parties  recognize  that the  services  to be provided by ProMedCo
shall be feasible  only if MH operates an active  medical  practice to which the
physicians associated with MH devote their full time and attention. To that end:



<PAGE>


                                                       -13-

         9.1 Restrictive Covenants by MH. During the term of this Agreement,  MH
shall not  establish,  operate  or provide  physician  services  at any  medical
office,  clinic or other health care facility providing  services  substantially
similar to those  provided by MH pursuant to this  Agreement  anywhere  within a
radius of 30 miles of Mayfield,  Kentucky, or within a radius of 30 miles of any
current or future  medical  office,  clinic or other health care  facility  from
which MH provides medical services.

         9.2  Restrictive  Covenants  By  Current  Physician   Shareholders  and
Physician  Employees.  MH  shall  enforce  employment  agreements,   in  a  form
satisfactory to ProMedCo,  with its current Physician Shareholders and Physician
Employees pursuant to which the Physician  Shareholders and Physician  Employees
agree not to  establish,  operate or provide  physician  services at any medical
office,  clinic or outpatient and/or ambulatory treatment or diagnostic facility
providing  services  substantially  similar to those  provided by MH pursuant to
this Agreement  within a radius of 30 miles of Mayfield,  Kentucky,  or within a
radius of 30 miles of any  current  or future  medical  office,  clinic or other
health care facility from which MH provides medical services, during the term of
said Physician Shareholder or Physician Employee's employment agreement, and for
a  period  equal  to the  lesser  of (i) one  year or (ii)  the  maximum  period
permitted by Kentucky law after any  termination of employment with MH. ProMedCo
shall have third-party rights to enforce such agreements.

         9.3  Restrictive  Covenants  By Future  Physician  Employees.  MH shall
obtain  and  enforce  formal  employment  agreements  from  each  of its  future
Physician   Shareholders  and  Physician  Employees,   pursuant  to  which  such
physicians agree not to establish,  operate or provide physician services at any
medical office,  clinic or outpatient and/or ambulatory  treatment or diagnostic
facility  providing  services  substantially  similar  to those  provided  by MH
pursuant to this Agreement within a radius of 30 miles of Mayfield, Kentucky, or
within a radius of 30 miles of any current or future medical  office,  clinic or
other health care facility from which MH provides medical  services,  during the
term of said Physician Employee's employment  agreement,  and for a period equal
to the lesser of (i) one year or (ii) the maximum  period  permitted by Kentucky
law after any termination of employment with MH. ProMedCo shall have third-party
rights to enforce such agreements.

         9.4 Physician  Shareholder and Physician Employee  Liquidated  Damages.
The  restrictive  covenants  described in Sections 9.2 and 9.3 of this Agreement
will provide that the Physician  Shareholders and Physician  Employees (existing
or future) may be released from their employment  agreement by paying Liquidated
Damages in the amount of one times such physician's  income,  as reported to the
Internal Revenue Service for the previous 12 months. In addition, if a Physician
Shareholder or Physician Employee received any ProMedCo  consideration  pursuant
to the Asset Purchase  Agreement,  and said  Physician  Shareholder or Physician
Employee  terminates  their  employment  agreement with MH for any reason (other
than death or  disability)  prior to the fifth  anniversary of the Closing under
the Asset  Purchase  Agreement,  or is  terminated  for cause by MH prior to the
fifth anniversary of the Closing under the Asset Purchase  Agreement,  then said
Physician  Shareholder or Physician Employee shall be required to reimburse back
to ProMedCo some or all of the consideration received by that physician pursuant
to the Asset Purchase Agreement as follows: (i) if such termination occurs prior
to the  third  such  anniversary,  100%  of  such  consideration;  (ii)  if such
termination  occurs thereafter and prior to the fourth such anniversary,  67% of
such


<PAGE>


                                                       -14-

consideration.; and (iii) if such termination occurs thereafter and prior to the
fifth such anniversary, 33% of such consideration. Such payments shall be passed
on to ProMedCo by MH simultaneously with the payment thereof by the physician to
MH. Such payment shall be first applied to all costs incurred by ProMedCo in the
enforcement  of the  employment  agreement for that  departing  physician and in
recruiting a replacement physician for that departing physician.  The remainder,
if any, shall become an additional  service fee to be paid to ProMedCo  pursuant
to Section 7. The  accounting  treatment  of such  funds  shall be  consistently
applied and approved by ProMedCo's  independent certified public accountants and
the Policy Council.

         9.5  Enforcement.  ProMedCo and MH  acknowledge  and agree that since a
remedy at law for any  breach or  attempted  breach  of the  provisions  of this
Section 9 shall be  inadequate,  either  party  shall be  entitled  to  specific
performance and injunctive or other equitable  relief in case of any such breach
or attempted  breach,  in addition to whatever  other remedies may exist by law.
All parties hereto also waive 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 Section 9 relating to 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  deemed to be reasonable  and
enforceable by the court shall thereafter be the time period, scope of activity,
restricted  and/or area of restriction  applicable to the  restrictive  covenant
provisions  in this  Section 9. The  invalidity  of  non-enforceability  of this
Section 9 in any respect shall not affect the validity of  enforceability of the
remainder of this Section 9 or of any other  provisions of this Agreement unless
the invalid or non-enforceable  provisions materially affect the benefits either
party would  otherwise be entitled to receive  under this Section 9 or any other
provision of this Agreement.

         9.6 Termination of Restrictive Covenants.  Notwithstanding  anything to
the contrary  contained  herein,  if this  Agreement is  terminated  pursuant to
Section 10.2 herein,  the employment  agreement term contained in this Section 9
shall be null and void and of no force or effect.

10.  TERM RENEWAL; TERMINATION;

         10.1 Term and Renewal. The term of this Agreement shall commence on the
date hereof and shall continue for 40 years, after which it shall  automatically
renew for five-year  terms unless either party  provides the other party with at
least 12 months but not more than 13 months  written notice prior to any renewal
date.

         10.2  Termination by MH.  MH may terminate this Agreement as follows:

                           creditors by ProMedCo,  or upon other action taken or
                           suffered,  voluntarily  or  involuntarily,  under any
                           federal  or state law for the  benefit  of debtors by
                           ProMedCo,  except  for the  filing of a  petition  in
                           involuntary  bankruptcy  against  ProMedCo  which  is
                           dismissed  within  30 days  thereafter,  MH may  give

                           suffered,  voluntarily  or  involuntarily,  under any

                           within 30 days  thereafter,  ProMedCo may give notice

12.  GENERAL PROVISIONS

         12.1 Independent Contractor.  It is acknowledged and agreed that MH and
ProMedCo  are at all  times  acting  and  performing  hereunder  as  independent
contractors.  ProMedCo  shall neither have nor exercise any control or direction
over the methods by which MH or the MH  Employees  practice  medicine.  The sole
function  of  ProMedCo  hereunder  is to provide  all  management  services in a
competent,  efficient and satisfactory  manner.  ProMedCo shall not, by entering
into and performing its obligations under this Agreement,  become liable for any
of the  existing  obligations,  liabilities  or  debts  of MH  unless  otherwise
specifically  provided for under the terms of this  Agreement.  ProMedCo will in
its management  role have only an obligation to exercise  reasonable care in the
performance of the management  services.  Neither party shall have any liability
whatsoever  for  damages  suffered  on  account  of the  willful  misconduct  or
negligence of any employee,  agent or independent contractor of the other party.
Each party shall be solely responsible for compliance with all state and federal
laws  pertaining  to  employment   taxes,   income   withholding,   unemployment
compensation contributions and other employment related statutes regarding their
respective employees, agents and servants.

     12.2 Other Contractual  Arrangement.  (a) The parties acknowledge and agree
that they have been  advised  and  consent  to the fact that  ProMedCo,  or it's
affiliates (i) may have, prior to the


<PAGE>


                                                       -20-

date of this Agreement,  discussed  proposals with respect to, or (ii) may, from
time to time  hereafter,  enter into agreements with one or more MH Employees to
provide consulting,  medical direction, advisory or similar services relating to
activities of ProMedCo or its  affiliates in clinical  areas.  The parties agree
that such agreement, if any, shall be entered into at the sole discretion of the
parties  thereto and subject to such terms and  conditions to which such parties
may agree, and any compensation payable to or by ProMedCo,  on the one hand, and
such MH Employees,  on the other hand, shall not constitute Net Clinic Revenues,
or MH Compensation, and shall otherwise not be subject to the provisions of this
Agreement.  (b) Each current  Physician  Shareholder,  by his  execution of this
Agreement  as provided on the  signature  page  hereof,  agrees that neither the
negotiation  nor the entry into any agreement or arrangement of a type described
in Section 12.2 (a) above shall  constitute  a breach of any  fiduciary or other
duty owned by any MH Employee to another, or by ProMedCo, to MH or any Physician
Shareholder.  Accordingly,  MH and each Physician  Shareholder  hereby waive any
right  to  disclosure  of the  negotiations,  proposals  or  terms  of any  such
agreement,  arrangement or right to participate in and/or share revenues derived
from any such agreement or arrangement with any MH Employee,  and hereby forever
release  and  discharge  MH, the  Physician  Shareholders,  ProMedCo,  and their
respective  representatives  (including,  but not limited to,  their  respective
attorneys, accountants,  affiliates, shareholders, officer, directors, employees
and  agents)  from any and all  actions,  claims,  charges,  suits,  damages and
liabilities  of  any  kind   whatsoever   arising  from  or  by  reason  of  the
participation  of any MH Employee in any agreement or arrangement with ProMedCo,
or their  affiliates of a type described in Section  12.2(a) above or from or by
reason  of  the  failure  of  ProMedCo,  any MH  Employee  or  their  respective
representatives  to disclose  the  negotiation,  existence  or terms of any such
agreement or  arrangement.  In keeping with the private nature of these matters,
the Physician  Shareholders  further agree that such negotiations,  proposals or
terms of agreement are to be kept confidential  between a MH Employee on the one
hand,  and  ProMedCo,  on the other hand,  and shall not be disclosed by them or
their representatives, except as required by applicable law.

         12.3  Proprietary Property.

                  12.3.1 Each party  agrees that the other  party's  proprietary
         property shall not be possessed,  used or disclosed  otherwise than may
         be  necessary  for  the  performance  of  this  Agreement.  Each  party
         acknowledges that its violation of this Agreement would cause the other
         party  irreparable  harm,  and may (without  limiting the other party's
         remedies  for such  breach) be  enjoined  at the  instance of the other
         party.  Each party agrees that upon  termination  of this Agreement for
         any reason,  absent the prior  written  consent of the other party,  it
         shall  have no right to and shall  cease  all use of the other  party's
         proprietary property, and shall return all such proprietary property of
         the other party in its possession to the other party.

                  12.3.2  ProMedCo  shall be the sole  owner  and  holder of all
         right, title and interest, to all intellectual property furnished by it
         under  this  Agreement,  including,  but not  limited to the trade name
         "ProMedCo,"  all  computer  software,   copyright,  services  mark  and
         trademark  right  to any  material  or  documents  acquired,  prepared,
         purchased or furnished by ProMedCo pursuant to this Agreement. MH shall
         have no right, title or interest in or to such material


<PAGE>


                                                       -21-

         and shall not, in any manner,  distribute  or use the same  without the
         prior written  authorization of ProMedCo,  provided,  however, that the
         foregoing  shall  not  restrict  MH  from  distributing   managed  care
         information  brochures and materials without the prior written approval
         of ProMedCo  provided no Proprietary  Property of ProMedCo is contained
         therein. Not withstanding the preceding,  however, ProMedCo agrees that
         MH shall be entitled to use on a nonexclusive and nontransferable basis
         for the term of this  Agreement  the name "MH" as may be  necessary  or
         appropriate  in  the  performance  of  MH's  services  and  obligations
         hereunder.

         12.4  Cooperation.  Each of the parties shall  cooperate fully with the
other  in  connection  with  the  performance  of their  respective  duties  and
obligations under this Agreement.

         12.5  Licenses,  Permits and  Certificates.  ProMedCo and MH shall each
obtain and maintain in effect, during the term of this Agreement,  all licenses,
permits  and  certificates  required  by  law  which  are  applicable  to  their
respective performance pursuant to this Agreement.

         12.6 Compliance with Rules, Regulations and Laws. ProMedCo and MH shall
comply with all federal and state laws and  regulations  in performance of their
duties and obligations hereunder.  Neither party, nor their employees or agents,
shall take any action that would jeopardize the other party's participation,  if
applicable,  in any  federal or state  health  program  including  Medicare  and
Medicaid.  ProMedCo and MH shall take particular care to ensure that no employee
or agent of either party takes any action  intended to violate  Section 1128B of
the Social  Security  Act with  respect to  soliciting,  receiving,  offering or
paying any remuneration  (including any kickback,  bribe, or rebate) directly or
indirectly,  overtly or covertly,  in cash or in kind 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 under Title
XVIII or XIX of the Social Security Act, or for purchasing,  leasing,  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
under Title XVIII or XIX of the Social Security Act.

         12.7 Generally  Accepted  Accounting  Principles  (GAAP). All financial
statements and  calculations  contemplated by this Agreement will be prepared or
made in accordance with generally accepted  accounting  principles  consistently
applied unless the parties agree otherwise in writing.

         12.8 Notices.  Any notices  required or permitted to be given hereunder
by either party to the other may be given by personal  delivery in writing or by
registered or certified mail,  postage prepaid,  with return receipt  requested.
Notices  shall be  addressed  to the parties at the  addresses  appearing on the
signature page of the Agreement,  but each party may change such party's address
by written  notice given in  accordance  with this  Section.  Notices  delivered
personally will be deemed communicated as of actual receipt; mailed notices will
be deemed communicated as of three days after mailing.

         12.9 Attorneys'  Fees.  ProMedCo and MH agree that the prevailing party
in any legal  dispute  among the parties  hereto shall be entitled to payment of
its attorneys' fees by the other party.

         12.10  Severability.  If any  provision of this  Agreement is held by a
court of competent  jurisdiction  or  applicable  state or federal law and their
implementing  regulations to be invalid,  void or  unenforceable,  the remaining
provisions will nevertheless continue in full force and effect.

         12.11 Arbitration.  Any controversy or claim arising out of or relating
to this Agreement or the breach  thereof will be settled by binding  arbitration
in  accordance  with  the  rules  of  commercial  arbitration  of  the  American
Arbitration   Association,   and  judgment  upon  the  award   rendered  by  the
arbitrator(s)  may be entered in any court  having  jurisdiction  thereof.  Such
arbitration  shall occur within the County of Graves,  Commonwealth of Kentucky,
unless the parties mutually agree to have such proceedings in some other locale.
The  arbitrator(s) may in any such proceeding award attorneys' fees and costs to
the prevailing party.

         12.12  Construction  of Agreement.  This Agreement shall be governed by
and construed in accordance with the laws of the State of Kentucky.  The parties
agree  that the terms and  provisions  of this  Agreement  embody  their  mutual
interest and agreement and that they are not to be construed  more  liberally in
favor of, nor more strictly against, any party hereto.

assign its rights  hereunder  to any person,  firm or  corporation  controlling,
controlled  by or  under  common  control  with  ProMedCo  and  to  any  lending
institution,  for security purposes or as collateral, from which ProMedCo or the
Parent  obtains  financing  for itself and as agent.  Except as set forth above,
neither ProMedCo nor MH shall have the right to assign their  respective  rights
and obligations hereunder without the written consent of the other party. MH may
not delegate  any of MH's duties  hereunder,  except as  expressly  contemplated
herein;  however,  ProMedCo  may  delegate  some or all of  ProMedCo'  s  duties
hereunder  to the  extent  it  concludes,  in its  sole  discretion,  that  such
delegation is in the mutual interest of the parties hereto.

         12.14  Confidentiality.  The terms of this  Agreement and in particular
the  provisions  regarding  compensation,  are  confidential  and  shall  not be

provision of this Agreement must be set forth specifically in writing and signed

provision.

this  Agreement  are  included for  purposes of  convenience  only and shall not
affect the construction or interpretation of any of its provisions.

         12.17 No Third Party Beneficiaries.  Nothing in this Agreement, express
or implied, is intended or shall be construed to confer upon any person, firm or
corporation  other than the parties  hereto and their  respective  successors or
assigns,  any remedy or claim under or by reason of this  Agreement or any term,
covenant or condition hereof, as third party beneficiaries or otherwise, and


<PAGE>


                                                       -23-

all of the terms,  covenants  and  conditions  hereof  shall be for the sole and
exclusive benefit of the parties hereto and their successors and assigns.

     12.18 Time is of the Essence.  Time is hereby  expressly  declared to be of
the essence in this Agreement.

         12.19  Modifications of Agreement for Prospective  Legal Events. In the
event any state or  federal  laws or  regulations,  now  existing  or enacted or
promulgated  after the effective  date of this  Agreement,  are  interpreted  by
judicial decision, a regulatory agency or legal counsel for both parties in such
a manner as to indicate that the structure of this Agreement may be in violation
of such laws or regulations, or in the event the Kentucky State Board of Medical
Examiners or other authority with legal jurisdiction  shall, solely by virtue of
this Agreement,  initiate an action to revoke,  suspend, or restrict the license
of any physician  retained by MH to practice  medicine in the State of Kentucky,
MH and ProMedCo shall amend this  Agreement as necessary.  To the maximum extent
possible,  any  such  amendment  shall  preserve  the  underlying  economic  and
financial  arrangements between MH and ProMedCo. In the event it is not possible
to amend this  Agreement  to preserve in all material  respects  the  underlying
economic and financial arrangements between MH and ProMedCo,  this Agreement may
be terminated by written notice by either party within 90 days from date of such
interpretation or action, termination to be effective no sooner than the earlier
of 180 days from the date notice of termination is given or the latest  possible
date  specified  for  such  termination  in  any  regulatory  order  or  notice.
Termination  pursuant to this Section 12.19 by MH shall require the  affirmative
vote of a majority of Physician Shareholders.

         12.20  Whole  Agreement  Modification;.  A contract in which the amount
involved exceeds $50,000 in value is not enforceable  unless the Agreement is in
writing  and  signed  by the  party to be bound  or by that  party's  authorized
representative.  The rights  and  obligations  of the  parties  hereto  shall be
determined solely from written  agreements.  Documents and instruments,  and any
prior oral agreements between the parties are superseded by and merged into such
writings.  This  Agreement  (As  amended  in  writing  from time to  time),  the
exhibits, and the schedules delivered pursuant hereto


<PAGE>


                                              -24-

represent  the  final  agreement  between  the  parties  hereto  and  may not be
contradicted  by;  evidence  of  prior,  contemporaneous,   or  subsequent  oral

                  determine the priority for any renovation, expansion plans and
                  major equipment  expenditures with respect to the Clinic based
                  upon economic feasibility, physician support, productivity and
                  market  conditions.  Any  capital  expenditure  in  excess  of
                  $10,000 shall require the approval of the Policy Council.

subject to the approval of the Policy Council.

         (g)      Grievance Issues.  Subject to the provisions of Section 1.2 of

                  and type of physicians required for the efficient operation of
                  the  Clinic  and  Tarrant  shall   determine  the   individual
                  physicians to be hired to fill such positions. The approval of
                  ProMedCo-LW  shall  be  required  for  any  variations  to the
                  restrictive covenants in any physician employment contract.

     (j) Provider and Payor  Relationships.  The Policy  Council  shall make the
decisions  regarding the  establishment  and maintenance of  relationships  with

3.  OBLIGATIONS OF PROMEDCO-LW

         During the term of this Agreement, ProMedCo-LW shall provide or arrange
for the  services set forth in this Section 3, the cost of all of which shall be
included in Clinic  Expenses.  ProMedCo-LW  is hereby  expressly  authorized  to
perform its  services in whatever  manner it deems  reasonably  appropriate,  in
accordance with policies  approved by the Policy Council,  and including without
limitation,  performance  of some  functions at locations  other than the Clinic
Facility.  Tarrant will not act in a manner which would prevent ProMedCo-LW from
efficiently  managing the Clinic Facility  operations in a businesslike  manner.
Tarrant,   through  Tarrant  Employees,   will  provide  all  medical  services.
ProMedCo-LW will have no authority, directly or indirectly, to perform, and will
not perform, any medical function.  ProMedCo-LW may, however,  advise Tarrant as
to the relationship between its performance of medical functions and the overall
administrative and business functioning of the Clinic.

         3.1 Management and  Administration.  During the term of this Agreement,
Tarrant  hereby  appoints  ProMedCo-LW  as the sole and  exclusive  manager  and
administrator  of all  non-medical  functions and services  related to Tarrant's
services  at the  Clinic.  Tarrant  shall  perform  all  medical  services,  and
ProMedCo-LW  shall have no authority,  directly or indirectly,  to perform,  and
will not perform,  any medical function.  Without limiting the generality of the
foregoing,  ProMedCo-LW shall provide the following  administrative,  management
and marketing services as may be required in conjunction with Tarrant's services
at the Clinic. ProMedCo-LW shall hire and supervise an Administrator, subject to
the reasonable  approval of the Policy Council,  to manage and administer all of
the day-to-day business functions of ProMedCo-LW, including without limitation:

                  3.1.1 Annual  Budgets.  Financial  planning and preparation of
         annual budgets. Annually and at least 30 days prior to the commencement
         of each fiscal year,  ProMedCo-LW  shall prepare and deliver to Tarrant
         capital  and  operating   budgets   reflecting  in  reasonable   detail
         anticipated  revenues  and  expenses,  sources  and uses of  capital to
         maintain and enhance Tarrant's medical practice and Clinic services.

                  3.1.2 Financial Statements.  ProMedCo-LW shall prepare monthly
         and fiscal year  unaudited  financial  statements  containing a balance
         sheet and a statement of income for Clinic  operations,  which shall be
         delivered  to Tarrant  within  thirty (30) days after the close of each
         calendar  month.  The fiscal  year  statement  shall be  reviewed  by a
         certified  public  accountant as selected by  ProMedCo-LW in connection
         with the audit of the  financial  statements  of  ProMedCo.  If Tarrant
         desires an audit in addition to the audit provided by ProMedCo-LW, such
         an audit would be at Tarrant's expense.

     3.1.3  Non-Physician  Personnel.  ProMedCo-LW  will  provide all  personnel
reasonably  necessary for the conduct of Clinic operations with the exception of

         salaries,  fringe benefits and any sums for income taxes,  unemployment
         insurance,  social  security  taxes or any  other  withholding  amounts
         required  by  applicable  law or  governmental  authority,  of all such
         personnel. Such personnel shall be under the direction, supervision and
         control of ProMedCo-LW,  with those personnel  performing  patient care
         services subject to the professional supervision of Tarrant. If Tarrant
         is dissatisfied with the services of any person,  Tarrant shall consult
         with ProMedCo-LW. ProMedCo-LW 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
         terminated.  All of ProMedCo-LW's  obligations regarding staff shall be
         governed by the overriding principle and goal of providing high quality
         medical care. At ProMedCo-LW's  option some or all of the non-physician
         personnel may be carried on the books of Tarrant as Tarrant's employees
         in which  event the costs  associated  with  such  employees  will be a
         Clinic Expense.

                  3.1.4 Quality  Assurance.  ProMedCo-LW  will assist Tarrant in
         fulfilling  its  obligation  to its  patients to maintain  high quality
         medical  and  professional  services,  including  patient  satisfaction
         programs,  employee  education,  outcomes  analysis,  clinical protocol
         development and to implement a risk management program.

                  3.1.5  Facilities and Equipment.  ProMedCo-LW  will ensure the
         proper cleanliness of the premises,  maintenance and cleanliness of the
         equipment, furniture and furnishings located on the premises.

                  3.1.6 Inventory Control and Purchasing  Supplies.  ProMedCo-LW
         shall  order  and  purchase  inventory  and  supplies,  and such  other
         ordinary,  necessary or appropriate  materials which  ProMedCo-LW shall
         deem to be necessary in the operation of the Clinic, to deliver quality
         Clinic services in a cost effective manner.

                  3.1.7   Managed   Care   Contracting.   ProMedCo-LW   will  be
         responsible for marketing,  negotiation,  and administering all managed
         care contracts,  subject to the provisions of Section 2.2(j); provided,
         however, no contract or arrangement regarding the provision of clinical
         services shall be entered into without Tarrant's consent.

                  3.1.8 Billing and Collections. ProMedCo-LW shall bill patients
         and  collect  all fees for  services  performed  inside or outside  the
         Clinic  Facility or arrange for such  billing and  collection.  Tarrant
         hereby appoints  ProMedCo-LW,  for the term hereof,  to be its true and
         lawful attorney-in-fact for the following purposes (i) to bill patients
         in  Tarrant's  name  and  on  its  behalf,  (ii)  to  collect  accounts
         receivable  resulting  from such billing in  Tarrant's  name and on its
         behalf,  (iii) to receive  payments  from Blue  Cross and Blue  Shield,
         Medicare,  Medicaid,  payments from health  plans,  and all other third
         party  payors;  (iv) to  receive  the  cash  proceeds  of any  accounts
         receivable;  (v) to  take  possession  of and  endorse  in the  name of
         Tarrant  (and/or in the name of an individual  physician,  such payment
         intended for purpose of payment of a

         physician's bill) any notes, checks,  money orders,  insurance payments
         and other instruments received in payment of accounts  receivable;  and
         (vi) in accordance  with  policies  adopted by the Policy  Council,  to
         initiate  legal  proceedings  in the name of  Tarrant  to  collect  any
         accounts  and  monies  owed to the  Clinic,  to  enforce  the rights of
         Tarrant as  creditors  under any  contract  or in  connection  with the
         rendering of any  service,  and to contest  adjustments  and denials by
         governmental  agencies (or its fiscal  intermediaries)  as  third-party
         payors. All adjustments made for uncollectible  accounts,  professional
         courtesies and other  activities that do not generate a collectible fee
         shall be done in a  reasonable  and  consistent  manner  acceptable  to
         ProMedCo- LW's independent certified public accountants.

                  3.1.9 Deposit of Net Clinic Revenues.  During the term of this
         Agreement,  all  Net  Clinic  Revenues  collected  resulting  from  the
         operations  of the  Clinic  shall  be  deposited  directly  into a bank
         account of which  Tarrant shall be the owner  ("Account").  ProMedCo-LW
         and Tarrant shall maintain their accounting records in such a way as to
         clearly  segregate Net Clinic  Revenues from other funds of ProMedCo-LW
         or Tarrant. Tarrant hereby appoints ProMedCo- LW as its true and lawful
         attorney-in-fact  to deposit in the  Account  all  revenues  collected.
         Tarrant  covenants,  and shall cause all Tarrant Employees to covenant,
         to forward any payments  received  with respect to Net Clinic  Revenues
         for services  provided by Tarrant and Tarrant  Employees to ProMedCo-LW
         for deposit.  ProMedCo-LW  shall have the right to withdraw  funds from
         the  Account and all owners of the  Account  shall  execute a revocable
         standing  transfer  order  ("Transfer  Order")  under  which  the  bank
         maintaining the Account shall periodically  transfer the entire balance
         of the Account to a separate bank account  owned solely by  ProMedCo-LW
         ("ProMedCo-LW  Account").  Tarrant  and  ProMedCo-LW  hereby  agree  to
         execute from time to time such documents and  instructions  as shall be
         required by the bank  maintaining  the Account and mutually agreed upon
         to  effectuate  the  foregoing  provisions  and to extend or amend such
         documents and instructions.  Any action by Tarrant that interferes with
         the  operation  of this  Section,  including,  but not  limited to, any
         failure to deposit or have ProMedCo-LW  deposit any Net Clinic Revenues
         into the  Account,  any  withdrawal  of any funds from the  Account not
         authorized by the express terms of this Agreement, 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  ProMedCo-LW,  in  addition  to any  other
         remedies that it may have at law or in equity,  to seek a court ordered
         assignment of the following rights:

     (a) To collect accounts receivable resulting from the provision of services
to patients of Tarrant and the Tarrant Employees;

                  (b)      To receive payments from patients,  third party payor
                           plans,  insurance companies,  Medicare,  Medicaid and

         7.2 Use of  Facilities.  Voluntary  abortions  will not be performed in
facilities  that are owned or leased by  ProMedCo-LW or any of its affiliates in
whole or in part.  ProMedCo-LW and Tarrant agree that Tarrant, as an independent
contractor,  is a separate organization that retains the authority to direct the
medical,  professional,  and  ethical  aspects  of its  medical  practice.  If a
Physician  Shareholder or a Physician  Employee performs abortion  procedures in

the revenue generated from such procedures.

8.  FINANCIAL ARRANGEMENTS

         8.1 Payments to Tarrant and ProMedCo-LW.  Tarrant and ProMedCo-LW agree
that  the  compensation  set  forth  herein  is  being  paid to  ProMedCo-LW  in
consideration of a substantial commitment made by ProMedCo-LW hereunder and that
such fees are fair and  reasonable.  As payment  for its  services  rendered  to
Tarrant,  each month ProMedCo-LW shall be paid the amount of all Clinic Expenses
and the  ProMedCo-LW  Distribution.  All Net Clinic  Revenues after deduction of
Clinic Expenses, and the ProMedCo-LW  Distribution,  shall be referred to as the
"Tarrant Distribution."

         8.2  Distribution.  The  amounts to be paid to  ProMedCo-LW  under this
Section  8.2 shall be payable  monthly.  ProMedCo-LW  shall pay to  Tarrant,  in
accordance with the provisions of Section 8.4, the Tarrant  Distribution amounts
on or about the 15th day of such  following  month.  Some amounts may need to be
estimated,  with  adjustments  made as necessary the following  month. Any audit
adjustments would be made after completion of the fiscal year audit.

         8.3 Clinic  Expenses.  Commencing  on the Effective  Date,  ProMedCo-LW
shall pay all Clinic Expenses as they fall due (including without limitation any
Non-Physician  Personnel  carried on the books of Tarrant at the  requirement of
ProMedCo-LW),  provided,  however,  that  ProMedCo-LW may, in the name of and on
behalf of Tarrant, contest in good faith any claimed Clinic Expenses as to which
there is any dispute regarding the nature, existence or validity of such claimed
Clinic  Expenses.  ProMedCo-LW  hereby  agrees  to  indemnify  and hold  Tarrant
harmless from and against any liability, loss, damages, claims, causes of action
and  reasonable  expenses  of Tarrant  resulting  from the contest of any Clinic
Expenses.

         8.4 Accounts Receivables. Except for the first month of this Agreement,
on  approximately  the 15th day of each month,  ProMedCo-LW  shall  purchase the
accounts  receivable of Tarrant arising during the previous month, by payment of
cash,  or  other  readily  available  funds  into an  account  of  Tarrant.  The
consideration  for  the  purchase  shall  be an  amount  equal  to  the  Tarrant
Distribution  for such  previous  month.  Although  it is the  intention  of the
parties  that  ProMedCo-LW  purchase  and thereby  become  owner of the accounts
receivable  of  Tarrant,  in case such  purchase  shall be  ineffective  for any
reason,  Tarrant,  as of the Effective Date of this Agreement,  grants and shall
cause each Tarrant Employee to grant to ProMedCo-LW a first priority lien on and
security  interest in and to any and all  interest  of Tarrant and such  Tarrant
Employees  in any  accounts  receivable  generated  by the  medical  practice of
Tarrant and the Tarrant Employees or otherwise  generated through the operations

Clinic,  and all  proceeds  with  respect  thereto,  to secure  the  payment  to
ProMedCo-LW of all such accounts receivable,  and this Agreement shall be deemed
to be a  security  agreement  to the  extent  necessary  to give  effect  to the
foregoing. In addition, Tarrant shall cooperate with ProMedCo-LW and execute and
deliver,  and cause each Tarrant Employee to execute and deliver,  all necessary
documents  in  connection  with  the  pledge  of  such  accounts  receivable  to
ProMedCo-LW or at ProMedCo-LW's  option, its lenders. All collections in respect
of such  accounts  receivable  shall be  deposited  in a bank  account at a bank
designated by ProMedCo-LW.  To the extent Tarrant or any Tarrant  Employee comes
into possession of any payments in respect of such accounts receivable,  Tarrant
or such Tarrant  Employee shall direct such payments to ProMedCo-LW  for deposit
in bank accounts designated by ProMedCo-LW.

9.  INSURANCE AND INDEMNITY

         9.1 Insurance to Be Maintained by  ProMedCo-LW.  Throughout the term of
this Agreement, ProMedCo-LW will use reasonable efforts to provide and maintain,

by Tarrant on the date  hereof if such  limits are at least  $200,000  per claim
with  aggregate  policy limits of at least  $600,000 per such  physician  with a
separate  limit for Tarrant.  Tarrant shall be responsible  for all  liabilities
(including  without  limitation  deductibles  and excess  liabilities)  not paid
within  the  limits  of such  policies.  ProMedCo-LW  shall  have the  option of
providing such professional  liability insurance through an alternative program,
provided such program meets the  requirements  of the Insurance  Commissioner of
the State of Texas and is approved by the Policy Council.

         9.3  Tail  Insurance  Coverage.  Tarrant  will  cause  each  individual
physician  associated  with the Clinic to enter into an  agreement  with Tarrant
that upon termination of such  physician's  relationship  with Tarrant,  for any
reason,  tail insurance coverage will be purchased by the individual  physician.
Such provisions may be contained in employment agreements,  restrictive covenant
agreements  or other  agreements  entered  into by  Tarrant  and the  individual
physicians,  and Tarrant  hereby  covenants  with  ProMedCo-LW  to enforce  such
provisions  relating to the tail insurance  coverage or to provide such coverage
at the expense of Tarrant.

         The parties  recognize  that the services to be provided by ProMedCo-LW

that end:

         10.1  Restrictive  Covenants  by  Tarrant.  During  the  term  of  this
Agreement, Tarrant shall not establish, operate or provide physician services at
any medical  office,  clinic or other health care  facility  providing  services

Employee's  employment  agreement,  and for a  period  of two  years  after  any

of 25 miles of the Clinic Facility or within a radius of 25 miles of any medical
office, clinic or other health care facility from which Tarrant provides medical
services or is in the process of developing.  ProMedCo-LW shall have third-party
rights to enforce such agreements.

         10.3 Restrictive Covenants By Future Physician Employees. Tarrant shall
obtain  and  enforce  formal  employment  agreements  from  each  of its  future
Physician Shareholders and Physician Employees in the form attached to the Asset
Purchase Agreement, pursuant to which such physicians agree that during the term
of  said  future  Physician   Shareholder  or  Physician  Employee's  employment
agreement,  and for a period of two years after any  termination  of  employment
with Tarrant,  not to establish,  operate or provide  physician  services at any
medical office,  clinic or outpatient and/or ambulatory  treatment or diagnostic
facility providing services  substantially  similar to those provided by Tarrant
pursuant to this Agreement within a radius of 25 miles of the Clinic Facility or

agreements.

         10.4  Physician Shareholder and Physician Employee Liquidated Damages.

         (a)      Release from Restrictive Covenants.  The restrictive covenants
                  described  in Sections  10.2 and 10.3 of this  Agreement  will
                  provide  that  the   Physician   Shareholders   and  Physician
                  Employees  (existing  or  future)  may be  released  from such
                  restrictive  covenants  by paying  Liquidated  Damages  in the
                  amount of one times  such  physician's  income  related to the
                  Clinic,  as reported to the Internal  Revenue  Service for the
                  previous 12 months.

     (b)  Repayment  of  Consideration  in Certain  Events.  In  addition,  if a
Physician   Shareholder   or  Physician   Employee   received  any   ProMedCo-LW
consideration  pursuant  to the Asset  Purchase  Agreement,  and said  Physician
Shareholder or Physician  Employee  terminates their  employment  agreement with
Tarrant  for any  reason  (other  than death or  disability)  prior to the fifth
anniversary of the Closing under the Asset Purchase Agreement,  or is terminated
for cause by Tarrant  prior to the fifth  anniversary  of the Closing  under the
Asset  Purchase  Agreement,  then Tarrant (or if the Physician  Shareholder  has
received any of the  consideration  paid to HealthFirst by ProMedCo-LW under the
Asset  Purchase  Agreement,  said Physician  Shareholder or Physician  Employee)
shall  be  required  to  reimburse  back  to  ProMedCo-LW  some  or  all  of the
consideration  received  by  Tarrant  (or  that  physician,  as the case may be,
pursuant to the Asset  Purchase  Agreement as follows:  (i) if such  termination
occurs prior to the third such anniversary, 100% of such consideration;  (ii) if
such termination occurs thereafter and prior to the fourth such anniversary, 67%
of such consideration; and (iii) if such termination occurs thereafter and prior
to the fifth such anniversary, 33% of such

                  consideration. Such payments shall be passed on to ProMedCo-LW
                  by  Tarrant  simultaneously  with the  payment  thereof by the
                  physician to Tarrant.  For the purposes of this clause (b) Dr.
                  Jay H.  Haynes,  III shall be deemed to have  received  38,697
                  shares of ProMedCo  Stock,  net of any reductions  required by
                  ss.  2.13(d)(i)(1)  of the Asset  Purchase  Agreement;  in the
                  event   the   management   agreement   contemplated   by   ss.
                  2.13(d)(i)(1)  of the Asset  Purchase  Agreement is terminated
                  under circumstances which, if it were a employment  agreement,
                  would require some or all of such consideration to be returned
                  hereunder  each  individual  of Tarrant who received  ProMedCo
                  Stock  as a result  of the  transactions  contemplated  by the
                  Asset Purchase  Agreement  shall be responsible  for returning
                  such  shares pro rata in  relation  to the number of shares of
                  the Stock  Consideration  (as  defined  in the Asset  Purchase
                  Agreement)  received by such individual.  All payments made to
                  ProMedCo-LW  under this  clause (b) shall be first  applied to
                  all costs incurred by  ProMedCo-LW  in the  enforcement of the
                  employment  or management  agreement,  as the case may be, for
                  that  departing  physician  and the balance,  if any,  held in
                  escrow by  ProMedCo-LW  to be used  solely  for new  physician
                  growth  within  Tarrant,  subject  to  approval  of the Policy
                  Council.  The  accounting  treatment  of such  funds  shall be
                  consistently applied and approved by ProMedCo-LW's independent
                  certified public accountants and the Policy Council.

         10.5  Enforcement.  ProMedCo-LW and Tarrant  acknowledge and agree that
since a remedy at law for any breach or attempted  breach of the  provisions  of
this Section 10 shall be inadequate,  either party shall be entitled to specific
performance and injunctive or other equitable  relief in case of any such breach
or attempted  breach,  in addition to whatever  other remedies may exist by law.
All parties hereto also waive 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 Section 10 relating to 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  deemed to be reasonable  and
enforceable by the court shall thereafter be the time period, scope of activity,
restricted  and/or area of restriction  applicable to the  restrictive  covenant
provisions  in this Section 10. The  invalidity  of  non-enforceability  of this
Section 10 in any respect shall not affect the validity of enforceability of the
remainder of this Section 10 or of any other provisions of this Agreement unless
the invalid or non-enforceable  provisions materially affect the benefits either
party would  otherwise be entitled to receive under this Section 10 or any other
provision of this Agreement.

         10.6 Termination of Restrictive Covenants.  Notwithstanding anything to
the contrary  contained  herein,  if this  Agreement is  terminated  pursuant to
Section 11.2 herein, the employment  agreement term contained in this Section 10
shall be null and void and of no force or effect.

obligations,  liabilities  or debts of  Tarrant  unless  otherwise  specifically
provided  for  under  the  terms  of  this  Agreement.  ProMedCo-LW  will in its
management  role have only an  obligation  to  exercise  reasonable  care in the
performance of the management  services.  Neither party shall have any liability
whatsoever  for  damages  suffered  on  account  of the  willful  misconduct  or
negligence of any employee,  agent or independent contractor of the other party.
Each party shall be solely responsible for compliance with all state and federal
laws  pertaining  to  employment   taxes,   income   withholding,   unemployment
compensation contributions and other employment related statutes regarding their
respective employees, agents and servants.

         13.2  Other Contractual Arrangement.

     (a) The  parties  acknowledge  and agree  that they have been  advised  and
consent to the fact that  ProMedCo-LW,  or its affiliates (i) may have, prior to
the date of this  Agreement,  discussed  proposals with respect to, or (ii) may,
from time to time  hereafter,  enter into  agreements  with one or more  Tarrant
Employees to provide consulting, medical direction, advisory or similar services
relating to activities of ProMedCo-LW or its affiliates in clinical  areas.  The
parties agree that such  agreements,  if any,  shall be entered into at the sole
discretion  of the parties  thereto and subject to such terms and  conditions to
which such parties may agree, and any compensation payable to or by ProMedCo-LW,
on the one  hand,  and such  Tarrant  Employees,  on the other  hand,  shall not
constitute Net Clinic Revenues, or Tarrant Compensation, and shall otherwise not
be subject to the provisions of this Agreement.

     (b) Each current Physician Shareholder,  by his execution of this Agreement
as provided on the signature  page hereof,  agrees that neither the  negotiation
nor the entry into any agreement or  arrangement  of a type described in Section
13.2(a) above shall  constitute a breach of any fiduciary or other duty owned by
any Tarrant Employee to another, or by ProMedCo-LW,  to Tarrant or any Physician
Shareholder.  Accordingly,  Tarrant and each Physician  Shareholder hereby waive
any right to  disclosure  of the  negotiations,  proposals  or terms of any such
agreement,  arrangement or right to participate in and/or share revenues derived
from any such agreement or  arrangement  with any Tarrant  Employee,  and hereby
forever release and discharge Tarrant, the Physician Shareholders,  ProMedCo-LW,
and their  respective  representatives  (including,  but not limited  to,  their
respective attorneys, accountants, affiliates, shareholders, officer, directors,
employees and agents) from any and all actions,  claims, charges, suits, damages
and  liabilities  of any  kind  whatsoever  arising  from  or by  reason  of the
participation  of any Tarrant  Employee in any  agreement  or  arrangement  with
ProMedCo-LW, or their affiliates of a type described in Section 13.2(a) above or
from or by reason of the failure of ProMedCo-LW,  any Tarrant  Employee or their
respective  representatives  to disclose the negotiation,  existence or terms of
any such agreement or  arrangement.  In keeping with the private nature of these
matters, the Physician

                  Shareholders  further agree that such negotiations,  proposals
                  or terms of agreement  are to be kept  confidential  between a
                  Tarrant  Employee on the one hand,  and  ProMedCo-  LW, on the
                  other  hand,  and  shall  not be  disclosed  by them or  their
                  representatives, except as required by applicable law.

         13.3  Proprietary Property.

                  13.3.1 Each party  agrees that the other  party's  proprietary
         property shall not be possessed,  used or disclosed  otherwise than may
         be  necessary  for  the  performance  of  this  Agreement.  Each  party
         acknowledges that its violation of this Agreement would cause the other
         party  irreparable  harm,  and may (without  limiting the other party's
         remedies  for such  breach) be  enjoined  at the  instance of the other
         party.  Each party agrees that upon  termination  of this Agreement for
         any reason,  absent the prior  written  consent of the other party,  it
         shall  have no right to and shall  cease  all use of the other  party's
         proprietary property, and shall return all such proprietary property of
         the other party in its possession to the other party.

                  13.3.2  ProMedCo-LW  shall be the sole owner and holder of all
         right, title and interest, to all intellectual property furnished by it
         under  this  Agreement,  including,  but not  limited to the trade name
         "ProMedCo,"  all  computer  software,   copyright,  services  mark  and
         trademark  right  to any  material  or  documents  acquired,  prepared,
         purchased or  furnished  by  ProMedCo-  LW pursuant to this  Agreement.
         Tarrant  shall have no right,  title or interest in or to such material
         and shall not, in any manner,  distribute  or use the same  without the
         prior written authorization of ProMedCo-LW, provided, however, that the
         foregoing  shall not restrict  Tarrant from  distributing  managed care
         information  brochures and materials without the prior written approval
         of  ProMedCo-LW  provided no  Proprietary  Property of  ProMedCo-LW  is
         contained therein.  Notwithstanding the preceding, however, ProMedCo-LW
         agrees that  Tarrant  shall be entitled  to use on a  nonexclusive  and
         nontransferable  basis for the term of this Agreement the name "Tarrant
         Family  Practice" as may be necessary or appropriate in the performance
         of Tarrant's services and obligations hereunder.

respective performance pursuant to this Agreement.

Tarrant  shall  comply  with all  federal  and  state  laws and  regulations  in
performance of their duties and obligations hereunder.  Neither party, nor their
employees  or  agents,  shall take any action  that would  jeopardize  the other
party's  participation,  if  applicable,  in any federal or state health program
including Medicare and

1128B of the Social Security Act with respect to soliciting, receiving, offering
or paying any remuneration  (including any kickback,  bribe, or rebate) directly
or indirectly,  overtly or covertly,  in cash or in kind in return for referring

provisions will nevertheless continue in full force and effect.

         (b) If the Policy  Council  determines  that the  relationship  between
ProMedCo  and  NTMS  (and  other  clinics  similarly  situated)  constitutes  an
"affiliated  service  group" (as defined in Code Section  414(m)),  ProMedCo and
NTMS  shall  take  such   actions  as  may  be   necessary   to  avoid  the  tax
disqualification  of the Plans. Such actions may include the amendment,  freeze,
termination or merger of the NTMS Plan.

         (c) NTMS  shall  not enter  into any new  "employee  benefit  plan" (as
defined  in  Section  3(3) of ERISA)  without  the  express  written  consent of
ProMedCo.  Except as otherwise required by law, NTMS shall not materially amend,
freeze,  terminate or merge any NTMS Plan without the express written consent of
ProMedCo. In the event of either of the foregoing,  ProMedCo's consent shall not
be withheld if such action would not jeopardize the  qualification of any of the
Plans.  NTMS agrees to make such  changes to NTMS' Plan,  including  the freeze,
termination, or merger of such NTMS Plan, as may be approved by ProMedCo.

         (d)  Expenses  incurred  in  connection  with  any  NTMS  Plan or other
employee  benefit plan  maintained by NTMS,  including  without  limitation  the
compensation of counsel, accountants,  corporate trustees and other agents shall
be included in Clinic Expenses.

         (e)  The  contribution  and   administration   expenses  for  Physician
Shareholders and Physician Employees shall be an expense of NTMS. ProMedCo shall
make  contributions  or  payments  with  respect to any NTMS  Plan,  as a Clinic
Expense,  on  behalf of  eligible  Technical  Employees  and  designated  leased
employees.

         (f)  ProMedCo  shall have the sole and  exclusive  authority  to adopt,
amend, or terminate any employee  benefit plan for the benefit of its employees,
regardless of whether such employees are  designated  leased  employees,  unless
such actions would require the amendment, freeze or termination of any NTMS Plan
to avoid  disqualification  of such plan, in which case any such action would be
subject to the express prior  written  consent of the Policy  Council.  ProMedCo
shall have the sole and exclusive  authority to appoint the trustee,  custodian,
and administrator of any such plan.

         (g)  In the event that any employee welfare benefit plan maintained or
sponsored by NTMS must be amended, terminated, modified, or changed as the


<PAGE>



result of NTMS and ProMedCo  being deemed to be a part of an affiliated  service
group,  the Policy  Council  will  replace any such plan or plans with a plan or
plans that provides those  benefits  approved by ProMedCo with the advice of the
Poky  Council.  It shall  be the goal of the  Policy  Council  in such  event to
provide  substantially  similar  or  comparable  benefits  that  the same can be
provided at a substantially similar cost to the replaced plan.

         4.11  Physician  Powers  of  Attorney.  NTMS  shall  require  all  NTMS
Employees to execute and deliver to ProMedCo powers of attorney, satisfactory in
form and substance to ProMedCo and NTMS, appointing ProMedCo as attorney-in-fact
for each for the purposes set forth in Section  3.1.9,  which powers of attorney
shall immediately terminate upon termination of this Agreement.

         4.12  Spokesperson.  NTMS shall  serve as  spokesperson  for  ProMedCo,
Parent and Clinic sales and development activities.  The parties agree that Drs.
Blucker,  Taylor and Shelton, or such other Physician Shareholders as the Policy
Council shall appoint, shall serve in this capacity on behalf of NTMS.

                                                    5.  RECORDS

         5.1 Patient  Records.  Upon  termination of this Agreement,  NTMS shall
retain all patient medical records maintained by NTMS or ProMedCo in the name of
NTMS. NTMS shall,  at its option,  be entitled to retain copies of financial and
accounting records relating to all services performed by NTMS.

         5.2    Other Records.  All records relating in any way to the operation
of the Clinic which are not the property of NTMS under the provisions of
Section 5.1 above, shall at all times be the property of ProMedCo.

         5.3  Access  to  Records.  During  the  term  of  this  Agreement,  and
thereafter,  NTMS or its accountant or other designee shall upon 24 hours notice
have  reasonable  access during normal  business  hours to NTMS's and ProMedCo's
financial  records,  including,  but not  limited  to,  records of  collections,
expenses  and  disbursements  as  kept  by  ProMedCo  in  performing  ProMedCo's
obligations under this Agreement, and NTMS may copy any or all such records.

                                     6.  FACILITIES TO BE PROVIDED BY PROMEDCO

         6.1  Facilities.  ProMedCo hereby agrees to provide as a Clinic Expense
the offices and facilities for Clinic operations,  including but not limited to,
the Clinic  Facility  and all costs of repairs,  maintenance  and  improvements,
utility (telephone,  electric, gas, water) expenses, normal janitorial services,
related real or personal  property  lease cost payments and expenses,  taxes and
insurance,  refuse disposal and all other costs and expenses reasonable incurred
in  conducting  operations  in the  Clinic  Facility  during  the  term  of this
Agreement.

         6.2 Use of  Facilities.  Voluntary  abortions  will not be performed in
facilities  that are owned or leased by  ProMedCo  or any of its  affiliates  in
whole  or in  part.  ProMedCo  and  NTMS  agree  that  NTMS,  as an  independent
contractor,  is a separate organization that retains the authority to direct the
medical,  professional,  and  ethical  aspects  of its  medical  practice.  If a
Physician  Shareholder or a Physician  Employee performs abortion  procedures in
any  facility,  ProMedCo  shall not receive any ProMedCo  Distribution  from the
revenue generated from such procedures.

                                            7.  FINANCIAL ARRANGEMENTS

         7.1 Payments to NTMS and  ProMedCo.  NTMS and  ProMedCo  agree that the
compensation  set forth herein is being paid to ProMedCo in  consideration  of a
substantial  commitment  made by ProMedCo  hereunder and that such fees are fair
and  reasonable.  As  payment  for its  services  rendered  to NTMS,  each month
ProMedCo  shall be paid the amount of all  Clinic  Expenses  and New  Investment
Expenses  and  the  ProMedCo  Distribution.  All  Net  Clinic  Revenues  and New
Investment Revenues after deduction of Clinic Expenses,  New Investment Expenses
and the ProMedCo Distribution, shall be referred to as the "NTMS Distribution."

         7.2  Calculation of Payments.  The amounts to be paid to ProMedCo under
this Section 7 shall be payable  monthly.  ProMedCo  shall,  to the extent it is
reasonably  able,  estimate such amounts by the 10th day of the following  month
and shall pay to NTMS in accordance  with the provisions of Section 7.4 the NTMS
Distribution  amounts  on or about the 15th day of such  following  month.  Some
amounts  may  need to be  estimated,  with  adjustments  made as  necessary  the
following  month.  Any audit  adjustments  would be made after completion of the
fiscal year audit.

         7.3 Clinic Expenses.  Commencing on the Effective Date,  ProMedCo shall
pay all Clinic Expenses as they fall due, provided,  however, that ProMedCo may,
in the name of and on behalf of NTMS,  contest in good faith any claimed  Clinic
Expenses as to which there is any dispute  regarding  the nature,  existence  or
validity of such claimed Clinic  Expenses.  ProMedCo  hereby agrees to indemnify
and hold NTMS harmless from and against any liability,  loss,  damages,  claims,
causes of action and  reasonable  expenses of NTMS resulting from the contest of
any Clinic Expenses.



<PAGE>




         7.4 Accounts Receivables.  On approximately the 15th day of each month,
ProMedCo  shall  purchase the  accounts  receivable  of NTMS arising  during the
previous  month,  by payment of cash, or other readily  available  funds into an
account of NTMS. The  consideration for the purchase shall be an amount equal to
the NTMS  Distribution for such previous month.  Although it is the intention of
the parties  that  ProMedCo  purchase  and thereby  become owner of the accounts
receivable of NTMS, in case such purchase shall be  ineffective  for any reason,
NTMS, as of the Effective  Date of this  Agreement,  grants and shall cause each
NTMS  Employee  to grant  to  ProMedCo  a first  priority  lien on and  security
interest in and to any and all  interest of NTMS and such NTMS  Employees in any
accounts  receivable  generated  by the  medical  practice  of NTMS and the NTMS
Employees or otherwise  generated through the operations of the Clinic,  and all
proceeds  with  respect  thereto,  to secure the payment to ProMedCo of all such
accounts  receivable,  and this  Agreement  shall  be  deemed  to be a  security
agreement to the extent necessary to give effect to the foregoing.  In addition,
NTMS shall cooperate with ProMedCo and execute and deliver,  and cause each NTMS
Employee to execute and deliver,  all necessary documents in connection with the
pledge of such  accounts  receivable to ProMedCo or at  ProMedCo's  option,  its
lenders.  All  collections  in  respect  of such  accounts  receivable  shall be
deposited in a bank account at a bank designated by ProMedCo. To the extent NTMS
or any NTMS  Employee  comes into  possession of any payments in respect of such
accounts  receivable,  NTMS or such NTMS Employee  shall direct such payments to
ProMedCo for deposit in bank accounts designated by ProMedCo.

         7.5  Additional  NTMS  Payments.  In addition to the NTMS  Distribution
provided for in Section 7.1 of this Agreement,  within 45 days following the end
of each fiscal quarter of ProMedCo,  ProMedCo shall  determine its net after-tax
income for such quarter,  in accordance with GAAP, and shall distribute to NTMS,
as an additional  payment,  an amount equal to 15% of such net after-tax income.
Any audit adjustments would be made after completion of the fiscal year audit.

         7.6 NTMS Advance.  In the event that for either of the second and third
years  following  the  Effective  Date of this  Agreement  (each  of such  years
hereafter referred to as the "Computation  Year"), the NTMS Distribution  amount
plus the  Additional  NTMS  Payments  payable to NTMS  pursuant  to Section  7.5
hereof,  payable to NTMS during such Computation Year  (collectively,  the "NTMS
Payments") are not equal to or greater than what would have been computed as the
Distribution Funds for North Texas Medical-Surgical,  P.A., the Seller under the
Asset  Purchase  Agreement,  (the  "Predecessor  Corporation")  for the 12-month
period  immediately  prior to the Effective Date of this Agreement  ("Historical
Distribution  Funds"),  then for such Computation Year NTMS shall be entitled to
an advance in accordance with the following terms:

         (a) For the Computation Year,  ProMedCo shall advance to NTMS an amount
equal to the difference,  if any, between the Historical  Distribution Funds and
the actual NTMS Payments for such Computation Year; provided,  however,  that in
no event shall the advance for any Computation Year exceed 15% of the Historical
Distribution Funds.

         (b) ProMedCo  shall be obligated to make such advance and NTMS shall be
eligible for such advance only in the event that the Net Clinic Revenues for the
Computation  Year are equal to or  greater  than the Net  Clinic  Revenue of the
Predecessor  Corporation  for the  12-month  period  immediately  preceding  the
Effective Date of this Agreement.

         (c)      For purposes of computing the advance amount set forth in
subparagraph (a) above, for each Computation Year the Historical Distribution


<PAGE>



Funds  shall  be  subject  to an  adjustment  in  the  event  that  during  such
Computation  Year all of the original  NTMS  shareholders  (other than Robert J.
Lee,  M.D. who is  retiring)  shall no longer be employed by NTMS on a full-time
basis. In such event, the Historical Distribution Fund for such Computation Year
shall be reduced by 1/7 of the Historical Distribution Fund amount for each such
original shareholder no longer employed on a full-time basis by NTMS.

     (d) The Computation  Year shall be a 12 month period which commences on the
second and third anniversary dates of the Effective Date of this Agreement.  The
advance,  if any,  shall be paid by  ProMedCo  within  15 days of  review of the
financial  statement by a certified  public  accountant,  as provided in Section
3.1.2 hereof, for each of such Computation Years.

         (e) With respect to any advance made in accordance  with the provisions
of this  Section,  ProMedCo  shall be  entitled to charge  interest  against the
balance of such advance at the minimum  applicable  federal rate for such period
of time as the advance shall remain outstanding.

         (f) Any advances made, and interest thereon,  shall be paid to ProMedCo
by NTMS  from  future  NTMS  Payments,  but only to the  extent  that  such NTMS
Payments exceed the Historical Distribution Funds.

                                            8.  INSURANCE AND INDEMNITY

         8.1 Insurance to be Maintained by ProMedCo. Throughout the term of this
Agreement,  ProMedCo will use reasonable  efforts to provide and maintain,  as a
Clinic  Expense,   comprehensive   professional   liability  insurance  for  all
professional employees of ProMedCo and NTMS with limits as determined reasonable
by ProMedCo in its national program,  comprehensive  general liability insurance
and property insurance covering the Clinic Facility and operations.

         8.2 Insurance to be Maintained by NTMS. Unless otherwise  determined by
the  Policy  Council,  throughout  the term of this  Agreement,  subject  to the
provisions  of Section 4.5 and Section 8.1,  NTMS shall  maintain  comprehensive
professional liability insurance with limits of not less than $500,000 per claim
and with aggregate policy limits of not less than $1,000,000 per physician and a
separate  limit  for  NTMS.  NTMS  shall  be  responsible  for  all  liabilities
(including  without  limitation  deductibles  and excess  liabilities)  not paid
within the limits of such policies.  ProMedCo shall have the option, with Policy
Council approval, of providing such professional  liability insurance through an
alternative  program,  provided  such  program  meets  the  requirements  of the
Insurance Commissioner of the State of Texas.

         8.3 Tail Insurance Coverage.  NTMS will cause each individual physician
associated  with the  Clinic  to enter  into an  agreement  with  NTMS that upon
termination of such  physician's  relationship  with NTMS, for any reason,  tail
insurance  coverage  will  be  purchased  by  the  individual  physician.   Such
provisions  may be  contained in  employment  agreements,  restrictive  covenant
agreements  or  other  agreements  entered  into  by  NTMS  and  the  individual
physicians,  and NTMS hereby  covenants with ProMedCo to enforce such provisions
relating  to the tail  insurance  coverage  or to provide  such  coverage at the
expense of NTMS.

         8.4      Additional Insured.  NTMS and ProMedCo agree to use their best
efforts to have each other named as an additional insured on the other's
respective professional liability insurance programs at ProMedCo's expense.


<PAGE>



         8.5  Indemnification.  NTMS shall  indemnify,  hold harmless and defend
ProMedCo,  its officers,  directors and employees,  from and against any and all
liability,  loss,  damage,  claim,  causes of action,  and  expenses  (including
reasonable  attorneys' fees), to the extent not covered by insurance,  caused or
asserted to have been caused,  directly or indirectly,  by or as a result of the
performance  of medical  services or any other acts or  omissions by NTMS and/or
its shareholders,  agents, employees and/or subcontractors (other than ProMedCo)
during  the  term  hereof,  including  any  claim  against  ProMedCo  by an NTMS
Employee, which claim arises out of such NTMS Employees' employment relationship
with NTMS or as a result of services performed by such NTMS Employee,  and which
claim  would  typically  be covered by  worker's  compensation.  ProMedCo  shall
indemnify, hold harmless and defend NTMS, its officers, directors and employees,
from and against any and all liability,  loss, damage,  claim, causes of action,
and expenses (including  reasonable  attorneys' fees), to the extent not covered
by insurance, caused or asserted to have been caused, directly or indirectly, by
or as a result of the  performance  of an  intentional  acts,  negligent acts or
omissions  by  ProMedCo  and/or  its  shareholders,   agents,  employees  and/or
subcontractors (other than NTMS) during the term of this Agreement.

                         9.   RESTRICTIVE COVENANTS AND LIQUIDATED DAMAGES

         The  parties  recognize  that the  services  to be provided by ProMedCo
shall be feasible only if NTMS operates an active medical  practice to which the
physicians  associated  with NTMS devote their full time and attention.  To that
end:

         9.1 Restrictive  Covenants by NTMS.  During the term of this Agreement,
NTMS shall not establish,  operate or provide physician  services at any medical
office,  clinic or other health care facility providing  services  substantially
similar to those  provided by NTMS pursuant to this  Agreement  anywhere  within
Denton County, Texas. The restrictive covenant contained within this Section 9.1
shall not apply to any Clinic Facility approved by the Policy Council.

         9.2  Restrictive  Covenants  By  Current  Physician   Shareholders  and
Physician  Employees.  NTMS shall  enforce the  employment  agreements  with its
current Physician  Shareholders and Physician  Employees  obtained in connection
with the Asset Purchase Agreement,  pursuant to which the Physician Shareholders
and Physician  Employees  agree not to establish,  operate or provide  physician
services at any medical office, clinic or outpatient and/or ambulatory treatment
or  diagnostic  facility  providing  services  substantially  similar  to  those
provided  by NTMS  pursuant to this  Agreement  within  Denton  County and for a
period  of  thirty-six  (36)  months  after  the  first  date of such  Physician
Shareholder's or such Physician Employee's  employment with NTMS. ProMedCo shall
have third-party rights to enforce such agreements.

         9.3 Restrictive  Covenants By Future  Physician  Employees.  NTMS shall
obtain  and  enforce  formal  employment  agreements  from  each  of its  future
Physician   Shareholders  and  Physician  Employees,   pursuant  to  which  such
physicians agree not to establish,  operate or provide physician services at any
medical office,  clinic or outpatient and/or ambulatory  treatment or diagnostic
facility  providing  services  substantially  similar to those  provided by NTMS
pursuant  to  this  Agreement  within  Denton  County  during  the  term of said
Physician  Employee's  employment  with NTMS and for a period of thirty-six (36)
months after the date of their first employment,  with NTMS. ProMedCo shall have
third-party rights to enforce such agreements.

         9.4   Physician Shareholder and Physician Employee Liquidated Damages.
The restrictive covenants described in Sections 9.2 and 9.3 of this Agreement
may provide that the Physician Shareholders and Physician Employees (existing


<PAGE>



or future) may be released from their restrictive covenants by paying Liquidated
Damages in the amount of $75,000. Such payment shall be made to ProMedCo by NTMS
simultaneously  with the payment by the physician to NTMS. Such payment shall be
first  applied to all costs  incurred  by  ProMedCo  in the  enforcement  of the
restrictive   covenant  for  that  departing   physician  and  in  recruiting  a
replacement physician for that departing physician. The remainder, if any, shall
become an additional  service fee to be paid to ProMedCo  pursuant to Section 7.
The  accounting  treatment  of such  funds  shall be  consistently  applied  and
approved by ProMedCo's  independent  certified public accountants and the Policy
Council.

         9.5 Additional  Covenants with Respect to Payor Contracts.  In addition
to the  restrictive  covenants set forth in Sections 9.2 and 9.3 of this Section
9, the employment agreements with Physician Shareholders and Physician Employees
shall  require  that  for  the  period  stated  hereafter  each  such  Physician
Shareholder and Physician  Employee shall not enter into a provider agreement or
other  contract  with,  nor provide any medical  services in connection  with or
pursuant to any such provider agreement or other contract, any third party payor
having a provider  agreement or other contract with NTMS or any NTMS Employee at
any time  within 120 days prior to and  including  the date of such  physician's
termination of employment  with NTMS. For Physician  Shareholders  and Physician
Employees  employed  by NTMS on the  date of  this  Agreement,  the  restrictive
covenants  contained  in this Section 9.5 shall apply for the  four-year  period
commencing on the first date of such Physician  Shareholder's  or such Physician
Employee's  employment  with NTMS.  For  Physician  Shareholders  and  Physician
Employees  who are not  employed  by NTMS  on the  date of this  Agreement,  the
restrictive  covenants set forth in this Section 9.5 shall apply for a period of
12  months  following  the date of such  Physician  Shareholder's  or  Physician
Employee's  termination of employment  with NTMS. As used herein,  a third party
payor shall include, without limitation,  any employer,  coalition of employers,
union or similar organization  maintaining a health benefit plan for the benefit
of its employees or members,  any insurance company,  any Blue Cross/Blue Shield
plan, any health  maintenance  organization,  preferred  provider  organization,
independent physicians association,  physician hospital organization, or similar
entity or arrangement  which  contracts for physician  services on behalf of its
employees or members or other third party  payors.  However,  as used herein the
term "third party payor" shall not include the federal  Medicare  program or the
state Medicaid program, although such terms shall include any health maintenance
organization providing Medicare or Medicaid benefits to plan participants.

         9.6  Enforcement.  ProMedCo and NTMS acknowledge and agree that since a
remedy at law for any  breach or  attempted  breach  of the  provisions  of this
Section 9 shall be  inadequate,  either  party  shall be  entitled  to  specific
performance and injunctive or other equitable  relief in case of any such breach
or attempted  breach,  in addition to whatever  other remedies may exist by law.
All parties hereto also waive 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 Section 9 relating to 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  deemed to be reasonable  and
enforceable by the court shall thereafter be the time period, scope of activity,
restricted  and/or area of restriction  applicable to the  restrictive  covenant
provisions  in this Section 9. The  invalidity  of non-  enforceability  of this
Section 9 in any respect shall not affect the validity of  enforceability of the
remainder of this Section 9 or of any other  provisions of this Agreement unless
the invalid or non-enforceable  provisions materially affect the benefits either
party would otherwise be entitled to


<PAGE>



receive under this Section 9 or any other provision of this Agreement.

         9.7 Termination of Restrictive Covenants.  Notwithstanding  anything to
the contrary  contained  herein,  if this  Agreement is  terminated  pursuant to
Section 10.2 herein, the restrictive covenants contained in this Section 9 shall
be null and void and of no force or effect.

                                          10.  TERM; RENEWAL; TERMINATION

         10.1 Term and Renewal. The term of this Agreement shall commence on the
date  hereof and shall  continue  for forty  (40)  years,  after  which it shall
automatically  renew for 5-year  terms unless  either  party  provides the other
party with at least  twelve (12)  months but not more than  fifteen (I 5) months
written notice prior to any renewal date.

follows:

     10.2.1 In the event of the filing of a petition in voluntary  bankruptcy or
an  assignment  for the benefit of creditors  by ProMedCo,  or upon other action
taken or suffered, voluntarily or involuntarily,  under any federal or state law
for the benefit of debtors by  ProMedCo,  except for the filing of a petition in
involuntary  bankruptcy  against  ProMedCo  which is  dismissed  within  30 days
thereafter, NTMS may give notice of the immediate termination of this Agreement.

     10.2.2 In the event ProMedCo shall materially default in the performance of
any duty or obligation  imposed upon it by this Agreement and such default shall

ProMedCo by NTMS;  or ProMedCo  shall fail to remit the payments due as provided
in Section 7 hereof and such failure to remit shall  continue for a period of 15
days  after  written  notice   thereof,   NTMS  may  terminate  this  Agreement.
Termination  of this  Agreement  pursuant to this  subsection  (2) by NTMS shall

     10.2.3    In the event ProMedCo intentionally misappropriates or misapplies
the NTMS Distribution.

     10.2.4  In the  event  a  court  of  competent  jurisdiction  makes a final
determination that ProMedCo has breached a fiduciary duty owed to NTMS.

     10.2.5 In the event Parent shall  default in any  obligation it may have to
purchase the Shares owned by any  Stockholder in accordance  with the provisions

NTMS dated of even date with this Agreement.

         10.3 Termination by ProMedCo.  ProMedCo may terminate this Agreement as
follows:

     10.3.1 In the event of the filing of a petition in voluntary  bankruptcy or
an  assignment  for the benefit of creditors by NTMS, or upon other action taken

the  benefit  of  debtors  by NTMS,  except  for the  filing  of a  petition  in
involuntary   bankruptcy   against  NTMS  which  is  dismissed  within  30  days
thereafter,  ProMedCo  may give  notice  of the  immediate  termination  of this
Agreement.

     10.3.2 In the event NTMS shall materially default in the performance of any
duty or obligation  imposed upon it by this Agreement or in the event a majority
of the Physicians  Shareholders  shall materially  default in the performance of
any  duty  or  obligation  imposed  upon  them  by this  Agreement  or by  their
employment agreements with NTMS, and such default shall continue for a period of
90 days after written  notice  thereof has been given to NTMS and such Physician
Shareholders by ProMedCo, ProMedCo may terminate this Agreement.

         10.4 Actions After Termination.  In the event that this Agreement shall
be terminated, the NTMS Compensation and the ProMedCo Distribution shall be paid
through the effective date of termination.  In addition,  the various rights and
remedies  herein  granted to the  aggrieved  party  shall be  cumulative  and in
addition to any others such party may be entitled to by law. The exercise of one
or more rights or remedies shall not impair the right of the aggrieved  party to
exercise any other right or remedy,  at law. Upon termination of this Agreement,
NTMS shall:



<PAGE>



         10.4.1  Asset  Repurchase.  Purchase  from  ProMedCo  at book value the
Restrictive  Covenants provided for in Section 9 and any other intangible assets
set forth on the Opening Balance Sheet, as adjusted  through the last day of the

         12.1  Independent  Contractor.  It is acknowledged and agreed that NTMS
and  ProMedCo are at all times acting and  performing  hereunder as  independent
contractors.  ProMedCo  shall neither have nor exercise any control or direction

function  of  ProMedCo  hereunder  is to provide  all  management  services in a
competent,  efficient and satisfactory  manner.  ProMedCo shall not, by entering
into and performing its obligations under this Agreement,  become liable for any
of the  existing  obligations,  liabilities  or debts of NTMS  unless  otherwise
specifically  provided for under the terms of this  Agreement.  ProMedCo will in
its management  role have only an obligation to exercise  reasonable care in the
performance of the management  services.  Neither party shall have any liability
whatsoever  for  damages  suffered  on  account  of the  willful  misconduct  or
negligence of any employee,  agent or independent contractor of the other party.
Each party shall be solely responsible for compliance with all state and federal
laws  pertaining  to  employment   taxes,   income   withholding,   unemployment
compensation contributions and other employment related statutes regarding their
respective employees, agents and servants.

         12.2     Other Contractual Arrangement.

                  (a) The  parties  acknowledge  and  agree  that they have been
advised and consent to the fact that  ProMedCo,  or its affiliates (i) may have,
prior to the date of this  Agreement,  discussed  proposals  with respect to, or
(ii) may, from time to time  hereafter,  enter into  agreements with one or more
NTMS Employees to provide  consulting,  medical  direction,  advisory or similar
services relating to activities of ProMedCo or its affiliates in clinical areas.
The parties agree that such agreement, if any, shall be entered into at the sole
discretion  of the parties  thereto and subject to such terms and  conditions to
which such parties may agree, and any compensation payable to or by ProMedCo, on
the one hand, and such NTMS Employees,  on the other hand,  shall not constitute
Net Clinic Revenues, or NTMS Compensation, and shall otherwise not be subject to
the provisions of this Agreement.

                  (b) Each current  Physician  Shareholder, by his execution of
this Agreement as provided on the signature page hereof, agrees that neither the
negotiation  nor the entry into any agreement or arrangement of a type described
in Section 12.2 (a) above shall  constitute  a breach of any  fiduciary or other
duty  owned by any NTMS  Employee  to  another,  or by  ProMedCo  to NTMS or any
Physician Shareholder.  Accordingly,  NTMS and each Physician Shareholder hereby
waive any right to  disclosure  of the  negotiations,  proposals or terms of any
such  agreement,  arrangement  or right to  participate in and/or share revenues
derived  from any such  agreement or  arrangement  with any NTMS  Employee,  and
hereby forever release and discharge NTMS, the Physician Shareholders, ProMedCo,
and their  respective  representatives  (including,  but not limited  to,  their
respective attorneys, accountants, affifiates, shareholders, officer, directors,
employees and agents) from any and all actions,  claims, charges, suits, damages
and  liabilities  of any  kind  whatsoever  arising  from  or by  reason  of the
participation  of  any  NTMS  Employee  in any  agreement  or  arrangement  with
ProMedCo,  or their  affiliates of a type described in Section  12.2(a) above or
from or by reason of the failure of


<PAGE>



ProMedCo, any NTMS Employee or their respective  representatives to disclose the
negotiation, existence or terms of any such agreement or arrangement. In keeping
with the private nature of these  matters,  the Physician  Shareholders  further
agree that such  negotiations,  proposals or terms of  agreement  are to be kept
confidential  between an NTMS  Employee on the one hand,  and  ProMedCo,  on the
other hand, and shall not be disclosed by them or their representatives,  except
as required by applicable law.

     12.3.1 Each party agrees that the other party's proprietary  property shall

limiting the other parts'  remedies for such breach) be enjoined at the instance
of the other party.  Each party agrees that upon  termination  of this Agreement
for any reason,  absent the prior written  consent of the other party,  it shall
have no  right to and  shall  cease  all use of the  other  party's  proprietary

pursuant to this Agreement. NTMS shall have no right, title or interest in or to
such  material and shall not, in any manner,  distribute or use the same without
the  prior  written  authorization  of  ProMedCo,  provided,  however,  that the
foregoing  shall not restrict NTMS from  distributing  managed care  information
brochures and materials  without the prior written approval of ProMedCo provided
no Proprietary  Property of ProMedCo is contained therein.  Notwithstanding  the
preceding,  however,  ProMedCo  agrees  that NTMS shall be  entitled to use on a
nonexclusive and  nontransferable  basis for the term of this Agreement the name

performance of NTMS' services and obligations hereunder.

that no employee or agent of either  party takes any action  intended to violate

implementing  regulations to be invalid,  void or  unenforceable,  the remaining
provisions will nevertheless continue in full force and effect.

(c)(i)Acquisition  Loans shall be available in the sole good faith discretion of
the Agent and the Required Lenders for the purpose of financing  Acquisitions by
the  Company,  in an  aggregate  principal  amount  not to  exceed  at any  time

Capital Loans.

(ii)Acquisition Loans may be made in such amounts and at such times as the Agent

Acquisition  and any  borrowing  of  Acquisition  Loans,  the Company  agrees to
provide  the  Agent  and  the  Lenders,  as soon as  practicable  following  the
execution thereof,  with copies of any term sheet or commitment letter agreed to
in  connection  with such  Acquisition.  As  promptly as  practicable  following
receipt of such termsheet and/or commitment,  the Agent and the Required Lenders
agree to notify the Company whether they can consent to the proposed Acquisition
as the  basic  terms  thereof  are  outlined  in the  documents  provided.  Such
indication shall be subject to approval of the definitive  documentation and the
results of any due diligence performed in connection  therewith.  At the time of
such approval, the Agent shall notify the Company of any due diligence materials
that it  wishes  to  review.  Promptly  upon the  completion  of the  definitive
documentation and as soon as the due diligence materials required are available,
the Company shall furnish a copy of such documentation  and/or such materials to
the  Agent  and the  Agent and the  Required  Lenders  agree to review  the same
promptly  and respond to the Company as  promptly as  practicable  as to whether
they approve the Acquisition.

in an aggregate  principal amount equal to the amount of such Lender's Revolving
Credit Commitment,  duly executed and delivered and payable to such Lender. Each
Lender  shall record the date and amount of each  Revolving  Credit Loan made by
it,  whether  such  Revolving  Credit  Loan  was a  Working  Capital  Loan or an
Acquisition  Loan,  and the date and amount of each payment of principal made by

Credit Note shall  endorse on Schedule A thereto (or any  continuation  thereof)
forming  a  part  thereof  appropriate   notations  to  evidence  the  foregoing
information  with respect to each such Revolving  Credit Loan then  outstanding;
provided  that  the  failure  of any  Lender  to make any  such  recordation  or
endorsement  shall not affect the obligations of the Company  hereunder or under
the Revolving Credit Notes. Each Lender is hereby irrevocably


                                                      -19-

authorized by the Company so to endorse its Revolving  Credit Note and to attach
to and  make a part of its  Revolving  Credit  Note a  continuation  of any such
schedule as and when required.

SECTION 2.03.  Interest on the Revolving Credit Loans. (a) The Company shall pay
interest on the Revolving  Credit Loans to the Lenders monthly in arrears on the
first (1st) day of each  calendar  month  immediately  succeeding  the month for
which such interest accrues, commencing with the first (1st) day of the calendar
month  following  the calendar  month in which the Closing  Date occurs.  In all
cases accrued  interest on all of the Revolving Credit Loans shall be payable by
the Company to the Lenders on the  Commitment  Termination  Date.  Interest that
accrues at the Default Rate shall be payable upon demand by the Lenders.  If any
interest on any of the Revolving  Credit Loans accrues or remains  payable after
the Commitment  Termination  Date, such interest shall be payable by the Company
upon demand by the Lenders.

(b)Except as provided in paragraphs (c) below, the Company shall be obligated to
pay  interest  to the  Lenders  on the  outstanding  principal  balance  of each
Revolving  Credit  Loan from the date such  Revolving  Credit Loan is made until
such  Revolving  Credit  Loan is repaid in full.  Subject  to  Section  2.03(e),
interest on all Loans  outstanding  during any month shall  accrue at a floating
rate per annum  (each such rate,  a "Floating  Rate")  equal,  at the  Company's
option,  to one of:  (i) the Index Rate plus  three and  one-quarter  percentage
points (3.25%), (ii) Adjusted LIBOR plus three and one-quarter percentage points
(3.25%), or (iii) the Prime Rate plus one-half of a percentage point (0.50%). On
the Closing Date, continuing through the last day of the calendar month in which
the Closing Date occurs and  thereafter  unless the Company  shall have selected
another rate or shall be deemed to have selected another rate as provided below,
the  Revolving  Credit  Loans  shall  bear  interest  based on the  Prime  Rate.
Thereafter,  provided  that no Default or Event of Default has  occurred  and is
then continuing,  and subject to the terms and conditions set forth herein,  the
Company may by written  notice (or by telephonic  notice  confirmed  promptly in
writing) delivered to the Agent not later than the Second Business Day preceding
the beginning of each calendar  month,  elect whether the Floating Rate for such
calendar  month  shall be based on the Prime Rate,  Adjusted  LIBOR or the Index
Rate  (each  such  notice  being  referred  to as a  "Notice  of  Floating  Rate
Election").  In the event that the  Company  shall fail to deliver any Notice of
Floating Rate Election on the date required  above,  provided that no Default or
Event of Default  shall have  occurred and be  continuing,  the Company shall be
deemed to have  delivered  a Notice of  Floating  Rate  Election  that elects to
continue in effect for the calendar  month the  Floating  Rate in effect for the
previous month.

(c)The Agent shall be entitled to rely upon and shall be fully  protected  under
this  Agreement in relying on any Notice of Floating Rate  Election  believed by
the Agent to be genuine and to assume that the persons giving the same on behalf
of the Company were duly  authorized  unless the responsible  individual  acting
thereon for the Agent shall have actual notice to the contrary.

(d)All  computations of interest hereunder or under the other Loan Documents for
Revolving Credit Loans shall be made by the Agent on the basis of a 360 day year
for the actual number of days


                                                      -20-

<PAGE>



occurring in the period for which such interest is payable.  Each  determination
by the Agent of an interest rate  hereunder  shall be conclusive and binding for
all purposes, absent manifest error.

(e)So long as any Event of Default  shall have occurred and be  continuing,  the
interest rate applicable to the Loans or other Obligations of the Company or any
of its  Subsidiaries  under the  Financing  Documents  may be  increased  by the
Required Lenders, at their option, by up to two percentage points (2%) per annum
above the rate otherwise applicable (the "Default Rate").

SECTION  2.04.  Advancing  Revolving  Credit Loans (a) Except as provided in the
last sentence of this Section 2.04(a),  each Revolving Credit Loan shall be made
on notice by the Company to the Agent,  given no later than 11:00 a.m. (New York
time) on the  Business Day of the proposed  Revolving  Credit Loan.  Such notice
(each a "Notice of Borrowing")  shall be  substantially in the form of Exhibit B
hereto,  shall be duly  completed and executed by an Authorized  Signatory,  and
shall specify  therein the requested  date and amount of such  Revolving  Credit
Loan, and such other information as may be required by the Agent. Each Notice of
Borrowing  shall  be given in  writing  (by  telecopy,  telex  or  cable)  or by
telephone and confirmed  immediately in writing.  Notwithstanding the foregoing,
no Notice of  Borrowing  that  requests an  Acquisition  Loan shall be effective
until the Agent  notifies the Company  that the Agent and the  Required  Lenders
have  consented to the proposed  Acquisition  after  having been  provided  such
information  respecting the proposed  Acquisition as is required to be delivered
pursuant  to Section  3.02 and such time to review the same as the Agent and the
Required Lenders shall reasonably deem necessary.

(b) Not later than 1:00 P.M. (New York City time) on the date of each  borrowing
specified in a Notice of Borrowing, each Lender shall make available its ratable
share of such  borrowing of Working  Capital  Loans,  in  immediately  available
funds, to the Company Account.

(c)The  failure of any Lender to make a Loan on any date shall not  relieve  any
other Lender of its obligation, if any, hereunder to make its Loan on that date.
Neither  the Agent nor any Lender  shall be  responsible  for the failure of any
other Person to make any Loan hereunder on the date required therefor.

SECTION 2.05.  Mandatory  Repayments and  Prepayments.  (a) The Revolving Credit
Commitment of each Lender shall  terminate at the opening of business on July 1,
2001 (the  "Commitment  Termination  Date"),  and there shall become due and the
Company shall pay on the Commitment  Termination  Date,  the entire  outstanding
principal amount of each Revolving Credit Loan, together with accrued and unpaid
interest thereon to but excluding the Termination Date.

(b)If at any time (i) the  aggregate  unpaid  principal  balance of the  Working
Capital Loans exceeds the Working  Capital  Availability,  or (ii) the aggregate
unpaid  principal  balance of the  Acquisition  Loans  exceeds  the  Acquisition
Availability,  then,  on the next  succeeding  Business  Day, the Company  shall
prepay Working Capital Loans and/or Acquisition Loans in an aggregate principal


                                                      -21-

continuing  on each  Quarterly  Date  thereafter,  the  Company  shall repay the

day following the last day of each Fiscal Year,  beginning  with the Fiscal Year
ending  December 31, 1998,  an aggregate  principal  amount of Revolving  Credit
Loans equal to fifty percent (50%) of the Excess Cash Flow for such Fiscal Year.

SECTION 2.06. Optional Prepayments.  The Company may prepay the Revolving Credit
Loans in whole or in part (in  minimum  principal  amounts of $100,000 or in any
larger integral multiple of $10,000,  or the total remaining amount outstanding)
upon at least three  Business  Days'  prior  irrevocable  written  notice to the
Lenders,  without  premium or penalty.  The  aggregate  principal  amount of the
Revolving  Credit  Loans  designated  for  prepayment  in any notice of optional
prepayment  given  pursuant to this section  shall become due and payable on the
date fixed for prepayment as specified in such notice.

SECTION 2.07.  Application of Payments.  Each payment or prepayment of less than
all the outstanding aggregate principal amount of the Acquisition Loans shall be
applied  pro rata to the  Acquisition  Loans of each Lender  according  to their
respective  outstanding  principal amounts. The principal amount of each payment
on Revolving  Credit Loans pursuant to Section  2.05(d) or Section 2.06 shall be
applied to reduce the remaining  payments required by Section 2.05(c) (i) 50% in
inverse  order of the  maturity  thereof  and (ii) 50% in the order of  maturity
thereof. Except as provided in the definition of Excess Cash Flow, no payment of
the principal amount of Acquisition  Loans pursuant to Section 2.05(b),  2.05(c)
or 2.06 shall reduce the amount of any payment required by 2.05(d). Each payment
of less than all outstanding aggregate principal amount of Working Capital Loans
shall be  applied  pro rata to all  Working  Capital  Loans  according  to their
respective outstanding principal amounts.

SECTION 2.08.  Reduction of  Commitments.  (a) The Revolving  Credit  Commitment
shall reduce: (i) to the amount of the aggregate outstanding principal amount of
the Revolving Credit Loans on the Availability  Termination Date, and after such
date by the amount of each payment made  pursuant to Section  2.06,  and (ii) by
the amount of each payment required pursuant to Section 2.05(c) or (d).

Agreement, or from time to time, irrevocably to reduce in part the amount of the

least  15  days'  prior  written  notice  to the  Agent.  Such  notice  shall be
irrevocable  on the part of the Company and shall specify the effective  date of
such reduction or termination, whether a termination or reduction is being made,
and, in the case of any  reduction,  the amount thereof shall be in an amount of
Two Million Five Hundred Thousand Dollars  ($2,500,000) or an integral  multiple
thereof.  Upon any such reduction,  the Company shall simultaneously  prepay any
outstanding Revolving Credit Loans to the extent necessary so that the aggregate
outstanding  principal  amount of the Revolving Credit Loans does not exceed the
amount of the  Revolving  Credit  Commitment  after giving effect to any partial
reduction thereof. The aforesaid prior notice requirement shall not apply to the
Agent's  exercise  of  remedies  under  Section  7.01.  In the event the Company
exercises its rights under this  paragraph to prepay the Revolving  Credit Loans
and terminate this Agreement,  the Company agrees that such prepayment  shall be
accompanied by the payment by the Company of all accrued and unpaid interest and
all fees and other  remaining  Obligations.  The amount of the Revolving  Credit
Commitment  may not be  reinstated  if it is  reduced  or if this  Agreement  is
terminated by the Company.

The Company  represents  and warrants as to itself and each of its  Subsidiaries

limitation,  accreditations  and  certifications  as a provider  of health  care
services  eligible to receive payment and compensation and to participate  under
Medicare,  Medicaid,  CHAMPUS or CHAMPVA).  The Company and each  Subsidiary  is
qualified to do business as a foreign  corporation in each jurisdiction in which
the  failure  of  the  Company  or  such  Subsidiary  to be so  qualified  could
reasonably be expected to have a Material Adverse Effect.

SECTION 4.02. Corporate and Governmental  Authorization;  No Contravention.  The
execution,  delivery and performance by the Company and each of its Subsidiaries
of the  Financing  Documents to which it is a party are within the  Company's or

authorized by all necessary corporate action, require no action by or in respect
of, or filing with, any  governmental  body,  agency or official (other than the

and effect) and do not contravene,  or constitute a default under, any provision
of applicable law or regulation  (including  specifically any applicable rule or
regulation  relating to the  eligibility of any Credit Party to receive  payment
and to  participate  as an  accredited  and  certified  provider  of health care
services  under  Medicare,  Medicaid,  CHAMPUS,  CHAMPVA or any Blue  Cross/Blue
Shield or  equivalent  program or relating to the licenses and permits  required
therein or in connection  therewith) or of the certificate of  incorporation  or
by-laws of the Company or any of its Subsidiaries or of any agreement, judgment,
injunction, order, decree or other instrument binding upon the Company or any of
its Subsidiaries or result in the creation or imposition of any Lien (other than
the Liens created by the Security  Documents) on any asset of the Company or any
of its Subsidiaries.

SECTION  4.03.  Binding  Effect;  Liens of Security  Documents.  (a) Each of the
Financing  Documents  to which the  Company is a party  (other  than the Notes,)
constitutes a valid and binding agreement of the Company, and each of the Notes,
when executed and delivered in accordance with this  Agreement,  will constitute
valid and  binding  obligations  of the  Company,  in each case  enforceable  in
accordance  with  its  respective  terms,  subject  to:  (i) the  effect  of any
applicable   bankruptcy,    fraudulent   transfer,    moratorium,    insolvency,
reorganization   or  other  similar  laws  affecting  the  rights  of  creditors
generally;  and (ii) the effect of general  principles of equity whether applied
by a court of equity or law.

(b)Each of the Financing  Documents to which any  Subsidiary of the Company is a
party constitutes a valid and binding  agreement of such Subsidiary  enforceable
in  accordance  with its terms,  subject  to:  (i) the effect of any  applicable
bankruptcy, fraudulent transfer, moratorium, insolvency, reorganization or other
similar laws affecting the rights of creditors generally; and (ii) the effect of
general principles of equity whether applied by a court of equity or law.

(c)The  Security  Documents  create valid security  interests in, the Collateral
purported to be covered  thereby,  which security  interests are and will remain
perfected  security  interests,  prior to all other Liens  other than  Permitted
Liens. Each of the representations and warranties made by the Company

consistent  basis the  consolidated  financial  position  of the Company and its
Consolidated  Subsidiaries  as of such date and their  consolidated  results  of
operations and cash flows for the periods then ended (subject to normal year-end
adjustments).  As of the date of the  latest  such  balance  sheet  and the date
hereof,  neither the Company nor any of its Subsidiaries had or has any material
liabilities, contingent or otherwise, including liabilities for taxes, long-term
leases or forward or long-term commitments,  which are not properly reflected on
such balance sheet.

(b)The  information  contained in the most  recently  delivered  Borrowing  Base

Receivables" have been determined as provided in the Financing Documents.

of whatever  nature that  constitutes,  or that could  reasonably be expected to
result in, a Material Adverse Effect.

SECTION  4.05.  Litigation.  There  is no  action,  suit or  proceeding  pending
against, or to the knowledge of the Company threatened against or affecting, the
Company  or any of its  Subsidiaries  before  any  court  or  arbitrator  or any
governmental  body,  agency or official  which, if adversely  determined,  could
reasonably be expected to have a Material  Adverse  Effect.  There is no action,
suit  or  proceeding  pending  against,  or to  the  knowledge  of  the  Company
threatened  against or affecting,  any party to any of the  Financing  Documents
before any court or  arbitrator  or any  governmental  body,  agency or official
which in any manner draws into  question  the  validity of any of the  Financing
Documents.  There is no pending investigation of any Credit Party by HCFA or any
other governmental authority,  which investigation is not otherwise conducted in
the ordinary course of business and no criminal, civil or administrative action,
audit,  or  investigation  by a fiscal  intermediary  or by or on  behalf of any
governmental  authority  exists or, to the best  knowledge  of the  Company,  is
threatened  with respect to any Credit Party which could  reasonably be expected
to  materially  and  adversely  affect  such  Credit  Party's  right to  receive
Medicare,  Medicaid, CHAMPUS or CHAMPVA reimbursement to which such Credit Party
would otherwise be entitled, or right to


                                                      -28-

have a Material Adverse Effect on the receipt of Medicare,  Medicaid, CHAMPUS or
CHAMPVA  reimbursement  by such Credit Party,  and, to the best knowledge of the
Company,  no Credit  Party is subject to any  pending but  unassessed  Medicare,
Medicaid,  CHAMPUS or CHAMPVA  claim payment  adjustments,  except to the extent
that  such  Credit  Party  is  contesting  such  assessment  in  good  faith  by
appropriate proceedings diligently pursued and has established and will maintain
adequate reserves for such adjustments in accordance with GAAP.

SECTION 4.06.  Ownership of Property,  Liens. On and as of the Closing Date, the
Company  and each  Subsidiary  is the lawful  owner of, has good and  marketable
title to and is in lawful  possession of, or has valid  leasehold  interests in,

mixed)  purported  to be owned or leased (as the case may be) by such  Person on
the balance  sheet  referred to in Section  4.04(a),  and none of such  Person's
properties  and  assets is subject to any Liens,  except  Permitted  Liens.  The
Company and its  Subsidiaries  conduct their business  without  infringement  or
claim of infringement of any material license,  patent,  trademark,  trade name,
service mark,  copyright,  trade secret or other intellectual  property right of
others and there is no  infringement  or claim of  infringement by others of any
material license, patent, trademark,  trade name, service mark, copyright, trade
secret  or  other  intellectual  property  right  of the  Company  or any of its
Subsidiaries.

SECTION 4.07. No Default.  No Default has occurred and is continuing and neither
the Company nor any of its  Subsidiaries  is in default under or with respect to
any material contract, agreement, lease or other material instrument to which it
is a party or by which its  property is bound or  affected.  Neither the Company
nor any other  Credit  Party has  received  notification  from any  governmental
authority  that any such  governmental  authority  has taken or  intends to take
action  to  revoke,  terminate  or  adversely  amend any  license,  certificate,
accreditation  or permit of such Person to operate a  healthcare  facility or to
participate under Medicare, Medicaid, CHAMPUS or CHAMPVA.

SECTION 4.08. No Burdensome Restrictions. No contract, lease, agreement or other
instrument  to which the  Company  or any of its  Subsidiaries  is a party or by
which  any  of  its  property  is  bound  or  affected,  no  charge,   corporate
restriction,  judgment,  decree or order and no provision of  applicable  law or
governmental  regulation  is  reasonably  likely to have or result in a Material
Adverse Effect.

SECTION  4.09.  Labor  Matters.  There are no  strikes or other  labor  disputes
pending  or, to the best  knowledge  of the  Company,  threatened,  against  the
Company  or any of its  Subsidiaries.  Hours  worked  and  payments  made to the
employees of the Company and its Subsidiaries  have not been in violation of the
Fair Labor Standards Act or any other  applicable law dealing with such matters.
All payments due from the Company or any of its  Subsidiaries,  or for which any
claim may be made  against  any of them,  on account of wages and  employee  and
retiree  health  and  welfare  insurance  and other  benefits  have been paid or
accrued as a liability on their books,  as the case may be. The  consummation of
the transactions contemplated by the Financing Documents will not give rise to


                                                      -29-

any  collective  bargaining  agreement  to which it is a party or by which it is
bound.

SECTION 4.10. Subsidiaries; Other Equity Investments. Other than as set forth on
Schedule 4.10,  the Company has no  Subsidiaries  on the date hereof.  Each such
Subsidiary is, and, in the case of any additional corporate  Subsidiaries formed
after the Closing Date, each of such additional  corporate  Subsidiaries will be
at each  time that this  representation  is made or deemed to be made  after the
Closing Date, a wholly-owned Subsidiary that is a corporation duly incorporated,
validly  existing and in good  standing  under the laws of its  jurisdiction  of
incorporation,  and has all  corporate  powers  and  all  material  governmental
licenses,  authorizations,  consents  and  approvals  required  to  carry on its
business as then conducted.  Neither the Company nor any of its  Subsidiaries is
engaged in any joint venture or partnership with any other Person.

SECTION 4.11. Investment Company Act. The Company is not an "investment company"
as defined in the Investment  Company Act of 1940, as amended.  The consummation
of the transactions  contemplated by the Financing Documents do not and will not
violate any provision of such Act or any rule, regulation or order issued by the
Securities and Exchange Commission thereunder.

SECTION 4.12. Margin Regulations.  None of the proceeds from the Loans have been
or will be used,  directly  or  indirectly,  for the  purpose of  purchasing  or
carrying  any  Margin  Stock,  for the  purpose  of  reducing  or  retiring  any
indebtedness which was originally incurred to purchase or carry any Margin Stock
or for any other purpose which might cause any of the loans under this Agreement
to be considered a "purpose  credit"  within the meaning of Regulation G, U or X
of the Board of Governors of the Federal Reserve Board.

SECTION  4.13.  Taxes.  The  Company's  federal  tax  identification  number  is
75-2529809  and the federal tax  identification  number for each  Subsidiary  is

of the  Company  and its  Subsidiaries  have  been  filed  with the  appropriate
governmental  agencies in all  jurisdictions in which such returns,  reports and
statements  are required to be filed,  and all taxes  (including  real  property
taxes) and other charges shown to be due and payable have been timely paid prior
to the date on which any fine,  penalty,  interest,  late  charge or loss may be

subject to a Permitted Contest. All state and local sales and use taxes required
to be paid by the Company or any of its Subsidiaries  have been paid, except any
of the foregoing as may be subject to a Permitted Contest. All Federal and state
returns have been filed by the Company and its  Subsidiaries for all periods for
which returns were due with respect to employee income tax  withholding,  social
security and  unemployment  taxes,  and the amounts  shown thereon to be due and
payable have been paid in full or adequate provisions therefor have been made.

SECTION  4.14.  Compliance  with  ERISA.  Each  member  of the  ERISA  Group has
fulfilled its

extensions  of credit under this  Agreement)  and the use or intended use of the
proceeds  of the  Notes,  except  that  the  Company  shall  have no  obligation
hereunder to an  Indemnitee  with respect to any  liability  resulting  from the
gross negligence or willful  misconduct of such  Indemnitee.  To the extent that
the  undertaking  set  forth  in  the  immediately  preceding  sentence  may  be
unenforceable,  the Company  shall  contribute  the maximum  portion which it is
permitted  to  pay  and  satisfy  under   applicable  law  to  the  payment  and
satisfaction of all such indemnified  liabilities incurred by the Indemnitees or
any of them.  Without  limiting the generality of any provision of this Section,
to the fullest extent permitted by law, the Company hereby waives all rights for
contribution  or any other  rights of  recovery  with  respect  to  liabilities,
losses,  damages,  costs and expenses arising under or relating to Environmental
Laws that it might have by statute or otherwise  against any Indemnitee;  except
to the extent that any thereof are finally  determined  by a court of  competent
jurisdiction to have resulted from the gross negligence or willful misconduct of
such Indemnitee.

SECTION 8.06.  Taxes.  The Company agrees to pay all  governmental  assessments,
charges or taxes (except  income or other similar taxes imposed on any Lender or
any holder of a Note),  including any interest or penalties thereon, at any time
payable  or ruled to be  payable  in  respect  of the  existence,  execution  or
delivery of this Agreement,  the other Financing  Documents,  or the issuance of
the Notes,  and to  indemnify  and hold each Lender and each and every holder of
the Notes harmless  against  liability in connection with any such  assessments,
charges or taxes.

SECTION  8.07.  Funding  Losses.  If the Company fails to borrow any Loans after
notice has been given to any Lender in accordance  with Section 2.04 or make any
payment when due (including  pursuant to a notice of optional  prepayment),  the
Company  shall  reimburse  each  Lender  within  15 days  after  demand  for any
resulting  loss or expense  incurred  by it (or by an  existing  or  prospective
participant  in the related  Loan),  including  any loss  incurred in obtaining,
liquidating  or employing  deposits from third  parties,  but excluding  loss of
margin for the period after any such payment or failure to borrow; provided that
such Lender shall have  delivered to the Company a  certificate  calculating  in
reasonable detail the amount of such loss or expense, which certificate shall be
conclusive in the absence of manifest error.

SECTION 8.08. Maximum Interest.  (a) In no event shall the interest charged with
respect to the Note or any other  obligations  of the Company or any  Subsidiary
under the Financing Documents exceed the maximum amount permitted under the laws
of the State of Georgia or of any other applicable jurisdiction.

(b)Notwithstanding  anything to the contrary herein or elsewhere, if at any time
the rate of interest  payable for the account of any Lender  hereunder  or under
the Note or other  Financing  Document  (the  "Stated  Rate")  would  exceed the
highest rate of interest  permitted  under any  applicable  law to be charged by
such Lender (the "Maximum Lawful Rate"),  then for so long as the Maximum Lawful
Rate would be so exceeded,  the rate of interest payable for the account of such
Lender shall be equal to the Maximum Lawful Rate; provided,  that if at any time
thereafter the Stated Rate is less


                                                      -55-

<PAGE>



than the Maximum Lawful Rate, the Company shall, to the extent permitted by law,
continue to pay  interest  for the account of such Lender at the Maximum  Lawful
Rate until such time as the total  interest  received by such Lender is equal to
the total  interest  which such Lender  would have  received had the Stated Rate
been (but for the  operation  of this  provision)  the  interest  rate  payable.
Thereafter,  the  interest  rate payable for the account of such Lender shall be
the Stated Rate unless and until the Stated Rate again would  exceed the Maximum
Lawful Rate, in which event this provision shall again apply.

(c)In no event shall the total interest received by any Lender exceed the amount
which such Lender could lawfully have received had the interest been  calculated
for the full term hereof at the Maximum Lawful Rate with respect to such Lender.

(d)In  computing  interest  payable with  reference  to the Maximum  Lawful Rate
applicable  to any Lender,  such  interest  shall be  calculated at a daily rate
equal to the Maximum  Lawful  Rate  divided by the number of days in the year in
which such calculation is made.

(e)If any Lender has received interest hereunder in excess of the Maximum Lawful
Rate with  respect to such  Lender,  such excess  amount shall be applied to the
reduction of the principal  balance of its Loans or to other amounts (other than
interest) payable hereunder,  and if no such principal or other amounts are then
outstanding, such excess or part thereof remaining shall be paid to the Company.


                                                    ARTICLE IX

                                                     THE AGENT

SECTION 9.01.  Appointment and Authorization.  Each Lender irrevocably  appoints
and  authorizes  the Agent to enter into each of the  Security  Documents on its
behalf  and to take such  action as agent on its  behalf  and to  exercise  such
powers under the Financing  Documents as are delegated to the Agent by the terms
thereof, together with all such powers as are reasonably incidental thereto.

SECTION 9.02. Agent and Affiliates. NationsCredit shall have the same rights and
powers  under the  Financing  Documents  as any other Lender and may exercise or
refrain  from  exercising  the  same as  though  it  were  not  the  Agent,  and
NationsCredit  and its affiliates may lend money to and generally  engage in any
kind of business with the Company or any  Subsidiary or affiliate of the Company
as if it were not the Agent hereunder.

SECTION 9.03.  Action by Agent.  The obligations of the Agent hereunder are only
those  expressly  set forth  herein  and under  the other  Financing  Documents.

required to take any action with  respect to any  Default,  except as  expressly
provided in Article VII.

SECTION  9.04.  Consultation  with  Experts.  The Agent may  consult  with legal
counsel (who may be counsel for the Company), independent public accountants and
other  experts  selected  by it and shall not be liable for any action  taken or
omitted  to be taken by it in good faith in  accordance  with the advice of such
counsel, accountants or experts.

SECTION 9.05.  Liability of Agent.  Neither the Agent nor any of its  directors,
officers,  agents or employees shall be liable for any action taken or not taken
by it in connection with the Financing  Documents (i) with the consent or at the
request  of the  Required  Lenders  or (ii)  in the  absence  of its  own  gross
negligence or willful  misconduct.  Neither the Agent nor any of its  directors,
officers,  agents  or  employees  shall be  responsible  for or have any duty to
ascertain, inquire into or verify (i) any statement,  warranty or representation
made in connection with any Financing Document or any borrowing hereunder;  (ii)
the  performance  or  observance  of any of the  covenants or  agreements of the
Company;  (iii) the  satisfaction  of any  condition  specified  in Article III,
except  receipt of items  required  to be  delivered  to the Agent;  or (iv) the
validity, effectiveness, sufficiency or genuineness of any Financing Document or
any other  instrument or writing  furnished in connection  therewith.  The Agent
shall not incur any  liability by acting in reliance  upon any notice,  consent,
certificate,  statement,  or other  writing  (which may be a bank  wire,  telex,
facsimile transmission or similar writing) believed by it to be genuine or to be
signed by the proper party or parties.

SECTION 9.06. Indemnification. Each Lender shall, ratably in accordance with its
Revolving Credit  Commitment  (whether or not the Revolving  Credit  Commitments
have been terminated),  indemnify the Agent (to the extent not reimbursed by the
Company) against any cost, expense  (including counsel fees and  disbursements),
claim, demand, action, loss or liability (except such as result from the Agent's
gross  negligence or willful  misconduct)  that the Agent may suffer or incur in
connection  with the  Financing  Documents or any action taken or omitted by the
Agent hereunder or thereunder.

SECTION  9.07.   Credit  Decision.   Each  Lender   acknowledges  that  it  has,
independently and without reliance upon the Agent or any other Lender, and based
on such  documents and  information as it has deemed  appropriate,  made its own
credit  analysis  and  decision to enter into this  Agreement.  Each Lender also
acknowledges that it will,  independently and without reliance upon the Agent or
any other Lender,  and based on such documents and  information as it shall deem
appropriate at the time,  continue to make its own credit decisions in taking or
not taking any action under the Financing Documents.

SECTION  9.08.  Successor  Agent.  The  Agent  may  resign at any time by giving
written  notice  thereof  to  the  Lenders  and  the  Company.   Upon  any  such
resignation, the Required Lenders shall have the

right to appoint a successor Agent which,  absent the occurrence and continuance
of a Default,  must be  reasonably  acceptable  to the Company.  If no successor
Agent  shall have been so  appointed  by the  Required  Lenders,  and shall have
accepted such appointment,  within 30 days after the retiring Agent gives notice
of resignation, then the retiring Agent may, on behalf of the Lenders, appoint a
successor Agent,  which shall be an institution  organized or licensed under the
laws  of the  United  States  of  America  or of any  State  thereof.  Upon  the
acceptance of its  appointment  as Agent  hereunder by a successor  Agent,  such
successor Agent shall thereupon succeed to and become vested with all the rights
and duties of the retiring  Agent,  and the retiring  Agent shall be  discharged
from  its  duties  and  obligations   hereunder.   After  any  retiring  Agent's
resignation  hereunder as Agent,  the  provisions of this Article shall inure to
its  benefit as to any  actions  taken or omitted to be taken by it while it was
Agent.

indemnities  and  agreements set forth in Articles VIII and IX shall survive the
payment of the Notes and the termination of this Agreement.

SECTION  10.02.  No  Waivers.  No failure or delay by the Agent or any Lender in
exercising  any right,  power or privilege  under any Financing  Document  shall
operate as a waiver  thereof  nor shall any single or partial  exercise  thereof
preclude  any other or further  exercise  thereof or the  exercise  of any other
right,  power or privilege.  The rights and remedies herein and therein provided
shall be cumulative and not exclusive of any rights or remedies provided by law.

forthwith  upon such  assignment)  or at such other address or telecopy or telex
number as such  party may  hereafter  specify  for the  purpose by notice to the
Agent and the Company. Each such notice, request or other communication shall be

SECTION 10.04.  Severability.  In case any provision of or obligation under this
Agreement or the Notes or any other Financing Document shall be invalid, illegal
or unenforceable in any jurisdiction,  the validity, legality and enforceability
of the remaining  provisions or obligations,  or of such provision or obligation
in any other jurisdiction, shall not in any way be affected or impaired thereby.

SECTION 10.05.  Amendments  and Waivers.  Any provision of this Agreement or the
Notes may be amended or waived if, but only if, such  amendment  or waiver is in
writing and is signed by the  Company  and the  Required  Lenders  (and,  if the
rights or duties of the Agent are affected thereby, by the Agent); provided that
no such  amendment  or  waiver  shall,  unless  signed by all the  Lenders,  (i)
increase or decrease any Revolving Credit Commitment of any Lender (except for a
ratable decrease in the Revolving Credit  Commitments of all Lenders) or subject
any Lender to any additional obligation, (ii) reduce the principal of or rate of
interest on any Loan or fees  hereunder,  (iii)  postpone the date fixed for any

which shall be required  for the Lenders or any of them to take any action under
this Section or any other provision of this Agreement.

SECTION 10.06. Successors and Assigns;  Registration. (a) The provisions of this
Agreement  shall be binding upon and inure to the benefit of the parties  hereto
and their  respective  successors  and assigns  (including any transferee of any
Note),  except that the Company may not assign or otherwise  transfer any of its
rights under this Agreement without the prior written consent of all Lenders.

(b)The terms and provisions of this Agreement  shall inure to the benefit of any
transferee  or assignee of any Note to which the Company,  in the absence of the
occurrence  and  continuance  of an Event of  Default  (in which case no consent
shall be required),  shall have consented  (such consent not to be  unreasonably
withheld)  and,  in the event of such  transfer  or  assignment,  the rights and
privileges herein conferred upon the assigning Lender shall automatically extend
to and be vested in such  transferee  or assignee,  all subject to the terms and
conditions  hereof.  Any  assignment  shall be for an equal  percentage  of such
assignor  Lender's  Loans  and its  Revolving  Credit  Commitment,  and any such
assignee Lender shall,  upon its  registration in the Note Register  referred to
below, become a "Lender" for all purposes  hereunder.  Upon any such assignment,
the assignor  Lender shall be released from its Revolving  Credit  Commitment to
the extent assigned to and assumed by the assignee Lender.  Notwithstanding  the
foregoing,  in the  absence of the  occurrence  and  continuance  of an Event of
Default, NationsCredit covenants for the benefit of the Company that it will not
assign  its  Revolving   Credit   Commitment  below   $15,000,000   except  that
NationsCredit retains the unrestricted right to transfer,  sell or assign any or
all of its interest and obligations in the Revolving  Credit  Commitment and the
Obligations  without  respect  to this  sentence  in the  following  cases:  the
transfer,  sale or  assignment  to any  Affiliate  of  NationsCredit,  (ii)  any
transfer, sale or assignment to any Person to the extent required to comply with
any order, directive or request from any

regulating authority, or (iii) any transfer, sale or assignment to any Person in
connection with the sale by NationsCredit  of all or any substantial  portion of
its corporate finance portfolio.

(c)Upon any assignment of any Note(s),  the assigning Lender shall surrender its
Note(s) to the Company for exchange or registration of transfer, and the Company
will promptly execute and deliver in exchange  therefor a new Note or Note(s) of
the same tenor and  registered in the name of the assignor  Lender (if less than
all of such Lender's Notes are assigned) and the name of the assignee Lender.

(d)The  Company shall  maintain a register (the "Note  Register") of the Lenders
and all assignee  Lenders that are the holders of all the Notes issued  pursuant
to this  Agreement.  The Company  will allow any Lender to inspect and copy such
list at the Company's  principal place of business during normal business hours.
Prior to the due  presentment  for  registration  of transfer  of any Note,  the
Company may deem and treat the Person in whose name a Note is  registered as the
absolute owner of such Note for the purpose of receiving payment of principal of
and premium and interest on such Note and for all other purposes whatsoever, and
the Company shall not be affected by notice to the contrary.

(e)Each Lender  (including any assignee  Lender at the time of such  assignment)
represents that it (i) is acquiring its Note solely for investment  purposes and
not  with a view  toward,  or for  sale in  connection  with,  any  distribution
thereof,  (ii) has received and reviewed such  information as it deems necessary
to  evaluate  the merits and risks of its  investment  in the Note,  (iii) is an
"accredited investor" within the meaning of Rule 501(a) under the Securities Act
and (iv) has such knowledge and experience in financial and business  matters as
to be capable of evaluating  the merits and risks of its investment in the Note,
including a complete loss of its investment.

(f)Each Lender  understands that the Note is being offered only in a transaction
not involving any public  offering within the meaning of the Securities Act, and
that,  if in the future  such  Lender  decides to  resell,  pledge or  otherwise
transfer the Note, the Note may be resold,  pledged or  transferred  only (i) to
the Company, (ii) to a person who such Lender reasonably believes is a qualified
institutional  buyer that  purchases for its own account or for the account of a
qualified  institutional buyer to whom notice is given that such resale,  pledge
or transfer is being made in reliance on Rule 144A under the  Securities  Act or
(iii) pursuant to an exemption from registration under the Securities Act.

(g)Each Lender  understands  that the Note will,  unless otherwise agreed by the
Company and the holder thereof, bear a legend to the following effect:

         THIS SECURITY IS NOT BEING REGISTERED UNDER THE SECURITIES ACT OF
         1933, AS AMENDED (THE "SECURITIES ACT"). THE HOLDER HEREOF, BY
         PURCHASING THIS SECURITY, AGREES FOR THE BENEFIT OF THE ISSUER THAT

<PAGE>



         THIS SECURITY MAY BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1)
         TO THE COMPANY, (2) TO A PERSON WHO THE SELLER REASONABLY BELIEVES IS A
         QUALIFIED INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A UNDER THE
         SECURITIES  ACT  PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A
         QUALIFIED  INSTITUTIONAL BUYER THAT IS AWARE THAT THE RESALE, PLEDGE OR
         OTHER  TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A OR (3)  PURSUANT
         TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT.

(h)If the Note becomes  mutilated and is  surrendered by the Lender with respect
thereto to the  Company,  or if any Lender  claims  that its Note has been lost,
destroyed or  wrongfully  taken,  the Company  shall execute and deliver to such
Lender a replacement  Note, upon the affidavit of such Lender  attesting to such
loss,  destruction  or wrongful  taking with respect to such Note and such lost,
destroyed, mutilated, surrendered or wrongfully taken Note shall be deemed to be
canceled  for  all  purposes  hereof.   Such  affidavit  shall  be  accepted  as
satisfactory evidence of the loss, wrongful taking or destruction thereof and no
indemnity  shall be required as a condition of the  execution  and delivery of a
replacement  Note.  Any costs and expenses of the Company in replacing  any such
Note shall be for the account of such Lender.

SECTION 10.07. Collateral.  Each of the Lenders represents to the Agent and each
of the other  Lenders that it in good faith is not relying upon any Margin Stock
as collateral in the extension or maintenance of the credit provided for in this
Agreement.

SECTION 10.08.  Headings.  Headings and captions used in the Financing Documents
(including  the Exhibits and Schedules  hereto and thereto) are included  herein
and therein for convenience of reference only and shall not constitute a part of
this Agreement for any other purpose or be given any substantive effect.

SECTION 10.09.  GOVERNING LAW;  SUBMISSION TO  JURISDICTION.  THIS AGREEMENT AND
EACH NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE  WITH THE LAWS OF THE
STATE OF GEORGIA. THE COMPANY HEREBY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF
THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF GEORGIA AND OF ANY
GEORGIA COURT SITTING IN THE CITY OF ATLANTA,  GEORGIA FOR PURPOSES OF ALL LEGAL
PROCEEDINGS  ARISING OUT OF OR RELATING TO THIS  AGREEMENT  OR THE  TRANSACTIONS

PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING
OF THE VENUE OF ANY SUCH  PROCEEDING  BROUGHT IN SUCH A COURT AND ANY CLAIM THAT
ANY SUCH PROCEEDING  BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT
FORUM. EACH OF THE PARTIES HERETO IRREVOCABLY

Company has knowledge,  or with the exercise of reasonable  diligence could have
had  knowledge,  of any such action or inaction),  the Company shall not assert,
and the Company  shall be deemed to have  waived,  any claim or defense  arising
therefrom to the extent that the Agent or any Lender could have  mitigated  such
claim or defense after receipt of such notice.
