Item 2.  Acquisition or Disposition of Assets

     On  October  1,  1997,  ProMedCo  Management  Company  ("ProMedCo"  or  the
"Company"),  a Delaware  corporation,  through its wholly owned subsidiary,  PHB
Management Company, Inc., ("PHB") acquired from HealthAmerica Pennsylvania, Inc.
("HealthAmerica")  substantially  all of the operating  assets of Beacon Medical
Group  ("Beacon"),  including  accounts  receivable and furniture and equipment.
Concurrent with the acquisition,  PHB entered into a long-term service agreement
(the "Service  Agreement") with Beacon.  Beacon has a total of 14 physicians and
two  physician  extenders  at four sites  serving the  Harrisburg,  Pennsylvania
market.  The total  consideration  for the  transaction was  approximately  $4.2
million, which consisted of a combination of cash and deferred cash payments and
the assumption of certain liabilities.  The consideration was determined through
arm's length negotiations between representatives of ProMedCo and HealthAmerica.
The factors  considered in determining  the purchase price included  information
with  respect to the  financial  condition,  assets,  liabilities,  business and
operations  of Beacon  on both a  historical  and  prospective  basis.  The cash
portion of the  purchase  price was  funded  with  proceeds  from the March 1997
public offering of the Company's Common Stock.

     Assets acquired will be used by PHB to provide  administrative  and medical
support services to Beacon pursuant to the terms of the Service Agreement.

(iv)     ProMedCo-Harrisburg    shall   pay    HealthAmerica,    as   contingent

         disbursed by HealthAmerica under Section 2 of the Inducement  Agreement
         for the  period  from July 1, 1997  through  the  Closing  Date had the
         Inducement  Agreement  been  in  effect  during  such  period  and  the
         obligations under such Section 2 commenced on July 1, 1997.

(b) In at other times, the following will occur:

(i)      As soon as the Definitive  Closing  Statement is prepared in accordance

         shall prepare and deliver to  HealthAmerica  a final closing  statement
         ("Final  Closing  Statement") of  HealthAmerica  as of August 12, 1997.
         ProMedCo-Harrisburg covenants that the Final Closing Statement shall be
         true, complete and accurate


<PAGE>



         and will present fairly the assets and  liabilities  items set forth in
         ss.ss.  2.1 and 2.2 hereof as at the August 12, 1997,  calculated  in a
         manner  consistent  with GAAP (except as disclosed in Exhibit 3.3B), as
         applied in the  HealthAmerica  Financial  Statements (as defined in ss.
         3.3), and the  requirements  of this Agreement.  HealthAmerica  and its
         representatives  shall be  provided  access to the books and records of
         ProMedCo-Harrisburg  as  necessary  to  verify  the  accuracy  of  such
         calculations.  If  within  30  business  days of  receipt  of the Final
         Closing    Statement,     HealthAmerica    fails    to    deliver    to
         ProMedCo-Harrisburg  written notice specifying any unacceptable entries
         on the Final Closing  Statements  and the reasons  therefor,  then such
         Final  Closing  Statement  shall  constitute  the  Definitive   Closing
         Statements.  If  HealthAmerica  timely and duly  delivers  such  notice
         within 30 business days of receipt  thereof,  the parties shall attempt
         in good faith to resolve the differences,  and if they are unable to do
         so,  within  20 days  thereafter  either  party may  deliver  the Final
         Closing Statement to a "big six" accounting firm mutually  agreeable to
         the parties (the "CPA Firm"), who shall have 20 business days to review
         the Final  Closing  Statement and make such  adjustments  thereto as it
         deems  necessary to ensure that the Final  Closing  Statement  has been
         prepared  in  a  manner   consistent   with  GAAP  as  applied  in  the
         HealthAmerica Financial Statements calculated on a consistent basis and
         the requirements of this Agreement.  The Final Closing  Statement as so
         adjusted shall constitute the Definitive Closing Statement and shall be
         binding  on  the  parties  hereto.  If  the  total  amount  payable  by
         ProMedCo-Harrisburg  pursuant to clause (b) below  increases  from that
         shown on the Final Closing Statement, ProMedCo-Harrisburg shall pay the
         fees and  expenses of the CPA Firm,  otherwise  such fees and  expenses
         shall be borne by HealthAmerica.  If the parties are unable to mutually
         agree on a CPA firm,  they  shall  select  one by using  the  following
         process: First  ProMedCo-Harrisburg shall nominate a "big six" firm; if
         that  firm is  unacceptable  to  HealthAmerica,  it  shall  nominate  a
         different   "big  six"   firm;   if  that  firm  is   unacceptable   to
         ProMedCo-Harrisburg,  each party shall  designate a partner of the firm
         nominated  by it, and the two  partners  shall choose a third "big six"
         firm which that thereupon be the "CPA Firm" contemplated hereby.

(b)      Balance Sheet  Adjustment.  To the extent that the  Definitive  Closing
         Statement  shows  Assets  at  Closing  net  of  Assumed  Balance  Sheet
         Liabilities  to be  different  from  the  same  assets  net of the same
         liabilities on the  HealthAmerica  Financial  Statements as of June 30,
         1997, the Consideration  shall be increased or reduced, as the case may
         be, on a dollar for dollar basis;  provided however,  if the adjustment
         is less than $5,000, neither party shall have an obligation to make any
         payment to the other.

being  conducted,   to  enter  into  this  Agreement,   and  to  consummate  the
transactions  contemplated  hereby. No jurisdiction  where  HealthAmerica is not
presently  qualified as a foreign  corporation  has made any assertion that such

Incorporation  and all  amendments  thereto of  HealthAmerica  and a copy of its
by-laws,  as amended to the date hereof  (both  certified  by the  Secretary  of
HealthAmerica to be true and correct copies as in effect as of the date hereof),

authority to enter into this Agreement and,  subject to approval by its Board of
Directors,  to carry out the transactions  contemplated  hereby.  The execution,
delivery,  and  performance of this Agreement  constitutes the valid and binding
agreement of  HealthAmerica  enforceable in accordance  with its terms,  and the
execution,  delivery and  performance  of this Agreement is not in conflict with
any other  agreement,  and will not result in the  acceleration or imposition of
any other obligation that will have a material adverse effect on the Assets.

         3.3  Financial  Statements.  Exhibit  3.3A  consists  of the  following
financial  statements of HealthAmerica:  unaudited schedule of assets and of the

directors, officers or employees of HealthAmerica, whether due to become payable
and regardless of when or by whom asserted) relating to the Clinic Facility. The

appropriate for the continued  operation of the Clinic  Facility.  HealthAmerica
shall  remove all liens and  encumbrances  on the Assets,  if any,  prior to the

sale and the assignments  and other  instruments to be executed and delivered by
HealthAmerica  at the  Closing  will be valid and  binding  and  enforceable  in
accordance  with  their   respective   terms,   and  will  effectively  vest  in
ProMedCo-Harrisburg   good  and   marketable   title  to  all  the  Assets.   If
HealthAmerica    shall   fail   to   remove   all   such   security   interests,
ProMedCo-Harrisburg  shall  have the right to do so and shall  have the right to
off-set the cost of doing so against the Cash  Consideration  payable  under ss.

employment  agreements or other agreements to which Health-America is a party or
by which  HealthAmerica  is bound that contain any severance or termination  pay
liabilities or obligations.

Alliance4Health NetSource Agreement.

         3.8 Burdensome Agreements. Except as is set forth in Exhibit 3.8 of the

any such affiliated person or entity.  Except as set forth on Exhibit 3.9, there
are no  debts  owing to  HealthAmerica  by,  or any  contractual  agreements  or
understandings  between HealthAmerica and, any shareholder,  director or officer
of HealthAmerica,  any member of their respective families,  or any affiliate or
associate  of any of the  foregoing  individuals,  as the  term  "affiliate"  is
defined for purposes of the Securities Act of 1933 and the rules and regulations
thereunder,  and none of the foregoing individuals or any affiliate or associate
of them owns any  property  or rights,  tangible  or  intangible  (other than an

<PAGE>






indenture, mortgage, contract, instrument or agreement to which HealthAmerica is
a party or by which  HealthAmerica  may be bound or under any  provision  of the
Articles of Incorporation or by-laws of HealthAmerica.  The execution,  delivery
and  performance  of this  Agreement and the  consummation  of the  transactions

injunction or decree of any court,  governmental agency or arbitration tribunal;
constitute a violation of or a default  under,  or a conflict  with, any term or
provision of the Articles of  Incorporation  or by-laws of  HealthAmerica or any

other restriction of any kind to which  HealthAmerica is a party or is bound; or
cause, or give any party grounds to cause (with or without  notice,  the passage

PURPOSE.  The  Inventory  is treated as a current  expense on the  HealthAmerica

have been additions or sales in the ordinary course of business.


         3.12 Equipment. All Assets consisting of equipment being sold hereunder
on an AS IS WHERE IS BASIS  WITHOUT ANY  WARRANTIES,  INCLUDING  ANY WARRANTY OF

<PAGE>



HealthAmerica  is not  required to obtain any  additional  permits,  licenses or
similar   authorizations   (including,   without   limitation,   any  additional
certificates of need) from any governmental  authority for the proper conduct of
its  business  or to  become a member of or  accredited  by any  association  or
governmental  authority  other than those  listed on Exhibit 3.14 in the Exhibit
Volume, and there are no proceedings  pending, or to the best of HealthAmerica's
knowledge,  threatened,  which  may  result  in  the  revocation,  cancellation,
suspension,  or other adverse  modification  of, any license or permit listed in
Exhibit 3.14. All of such permits,  licenses and authorizations will continue to
be valid and in full force and effect in accordance with their  respective terms
after the consummation of the transactions contemplated hereby.

         3.15  Litigation,  etc.  Except  as set  forth in  Exhibit  3.15 of the
Exhibit  Volume,  there  is  no  litigation,  arbitration,  governmental  claim,
investigation or proceeding  pending or, to the best knowledge of HealthAmerica,
threatened  against  HealthAmerica  at  law  or in  equity,  before  any  court,
arbitration  tribunal or  governmental  agency.  No such proceeding set forth in
Exhibit 3.15  concerns the ownership or other rights with respect to the Assets.
To the best  knowledge  of  HealthAmerica,  there  are no  facts  based on which
material claims may be hereafter made against HealthAmerica.  Any and all claims
arising  from  incidents  on or  before  the  Closing  Date  shall  be the  sole
responsibility  of  HealthAmerica   and  are  specifically   excluded  from  the
liabilities  to be  assumed  by  ProMedCo-Harrisburg  hereunder.  All claims and
litigations against HealthAmerica are fully covered by insurance.  HealthAmerica
shall unconditionally  indemnify and hold  ProMedCo-Harrisburg  harmless against
any loss or liability including, without limitation,  attorney's fees, resulting
from any claims or litigation arising out of incidents relating to HealthAmerica
which  occurred  prior to the Closing Date, to the extent such loss or liability
is not covered by insurance.

         3.16 Court Orders,  Decrees and Laws.  There is not  outstanding or, to
the best knowledge of HealthAmerica,  threatened any order, writ,  injunction or
decree of any court,  governmental  agency or  arbitration  tribunal  against or
affecting  HealthAmerica or the Assets.  HealthAmerica is in compliance with all
applicable federal,  state and local laws, regulations and administrative orders
which are  material  to the  business of  HealthAmerica  and  HealthAmerica  has
received no notices of alleged violations thereof.  No governmental  authorities
are  presently  conducting  proceedings  against  HealthAmerica  and to the best
knowledge of  HealthAmerica,  no such  investigation or proceeding is pending or
being threatened.

         3.17 Taxes.  All federal,  state and other tax returns of HealthAmerica
required by law to be filed have been timely filed, and  HealthAmerica  has paid
or provided for all taxes  (including taxes on properties,  income,  franchises,
licenses,  sales and payrolls) which have become due pursuant to such returns or
pursuant to any  assessment,  except for any taxes and  assessments of which the
amount,  applicability or validity is currently being contested in good faith by
appropriate proceedings and with respect to which HealthAmerica has set aside on
its  books  adequate  reserves.  All such tax  returns  have  been  prepared  in
compliance with all applicable laws and


<PAGE>






regulations and are true and accurate in all respects. There are no tax liens on
any of the Assets except those with respect to taxes not yet due and payable and
except  for any taxes and  assessments  of which the  amount,  applicability  or
validity is currently being  contested in good faith by appropriate  proceedings
and with  respect  to which  HealthAmerica  has set aside on its books  adequate
reserves. There are no pending tax examinations nor has HealthAmerica received a
revenue agent's report asserting a tax deficiency. HealthAmerica does not expect
any taxing  authority to claim or assess any amount of additional  taxes against
it. No claim has ever been made by a taxing  authority in a  jurisdiction  where
HealthAmerica  does not file tax returns that HealthAmerica is or may be subject
to taxes  assessed by such  jurisdiction.  HealthAmerica  has withheld from each
payment  made to its  employees  the  amount  of all taxes  (including,  but not
limited  to,  federal,  state  and local  income  taxes  and  Federal  Insurance
Contribution  Act taxes)  required  to be  withheld  therefrom  and all  amounts
customarily   withheld   therefrom,   and  has  set  aside  all  other  employee
contributions  or payments  customarily set aside with respect to such wages and
has paid or will pay the same to, or has  deposited or will deposit such payment
with, the proper tax receiving officers or other appropriate authorities, except
to the extent of any liabilities to be assumed by ProMedCo-Harrisburg  under ss.
11.3 hereof.

         3.18 Immigration Act.  HealthAmerica is in material compliance with the
terms and provisions of the Immigration Act in all material  respects.  For each
employee  (as  defined in 8 C.F.R.  ss.  274a.I(f))  of  HealthAmerica  for whom
compliance with the Immigration Act by HealthAmerica is required,  HealthAmerica
has obtained and retained a complete and true copy of each such  employee's Form
I-9  (Employment  Eligibility  Verification  Form)  and  all  other  records  or
documents  prepared,  procured  or  retained  by  HealthAmerica  pursuant to the
Immigration  Act.  There  are  no  violations  or  potential  violations  of the
Immigration  Act by  HealthAmerica.  HealthAmerica  has not been  cited,  fined,
served with a Notice of Intent to Fine or with a Cease and Desist Order, nor, to
HealthAmerica's  knowledge,  has any action or  administrative  proceeding  been
initiated  or  threatened  against  HealthAmerica,  by reason  of any  actual or
alleged failure to comply with the Immigration Act.

         3.19 Program Compliance. To the best of HealthAmerica's knowledge after
due inquiry,  neither  HealthAmerica nor any of its  shareholders,  employees or
agents have engaged in or is being  investigated  for any  activities  which are
prohibited  under  either (a)  Section  1320a-7a  or 1320a-7b of Title 42 of the
United States Code, (b) Section 1395nn of Title 42 of the United States Code, or
(c)  Section  3729 of Title 31 of the United  States  Code,  or the  regulations
promulgated  thereunder,  or any similar or related  state or local  statutes or
regulations,   or  which  are  prohibited  by  rules  of  professional  conduct,
including,  but not limited  to, the  following:  (1)  knowingly  presenting  or
causing to be presented a false claim for payment; (2) knowingly making or using

material fact in any application  for any benefit or payment;  (4) knowingly and
willfully making or causing to be made any false statement or  representation of
a material fact for use in determining rights to any benefit or payment; (5) any
failure by a claimant  to  disclose  knowledge  of the  occurrence  of any event
affecting  the initial or  continued  right to any benefit or payment on its own
behalf or on behalf of  another,  with the intent to  fraudulently  secure  such
benefit or payment;  (6)  knowingly  and  willfully  soliciting or receiving any
remuneration  (including any kickback,  bribe or rebate) directly or indirectly,
overly or  covertly,  in cash or in kind,  or  offering  to pay or receive  such
remuneration  (A) in return  for  referring  an  individual  to a person for the
furnishing  or  arranging  for the  furnishing  of any item or service for which
payment  may be made in  whole or in part by  Medicare  or  Medicaid,  or (B) in
return for  purchasing,  leasing or ordering or arranging for, or  recommending,
purchasing,  lease or  ordering  any good,  facility,  service or item for which
payment  may be  made  in  whole  or in part by  Medicare  or  Medicaid;  or (7)

         3.20  Environmental Matters.  Except as disclosed on Exhibit 3.20:

         (a)      There are no  outstanding  violations  or any consent  decrees
                  entered against HealthAmerica regarding environmental matters,
                  including,  but not limited to, matters affecting the emission
                  of air  pollutants,  the  discharge of water  pollutants,  the
                  management  of hazardous  or toxic  substances  or wastes,  or
                  noise.

         (b)      There are no claimed,  threatened or alleged  violations  with
                  respect  to any  federal,  state or local  environmental  law,
                  rule, regulation, ordinance, permit, license or authorization,
                  and there are no present  discussions with any federal,  state

          summaries of material  modifications  pertaining thereto, (iii) copies
          of the most recent Internal Revenue Service determination  letters, if
          any,  relating to such plans, (iv) copies of the last three (3) years'
          Annual Report (Form 5500 series),  as filed with respect to such plans
          with the Internal  Revenue  Service,  together  with all Schedules and
          attachments thereto, including, without limitation, copies of the plan

          (within  the  meaning  of  Section  3(1) of  ERISA)  that  has been in
          existence during any part of the last three years.

         (c)      No  "prohibited  transaction",  as such term is defined  under
                  Section 4975(c) of the Code or under Section 406 of ERISA, and
                  the  respective  regulations  thereunder,  has  occurred or is
                  occurring   with  respect  to  any  "employee   benefit  plan"
                  maintained by  HealthAmerica or with respect to any trustee or
                  administrator thereof.

         3.22  Pension, etc.

         (a)      No "unfunded accrued liability", as such term is defined under
                  Section  3(30) of ERISA,  exists with respect to any "employee
                  pension  benefit plan" listed in Exhibit 3.21 (each a "Pension
                  Plan" and collectively the "Pension Plans").

         (b)      None of the  Pension  Plans or any  related  trusts  have been
                  partially or fully terminated  (through the complete cessation

                  adverse  effect on the condition,  financial or otherwise,  of
                  HealthAmerica.

     (d)  With respect to each  Pension  Plan,  there are not in  existence  any
          liabilities  other than those  liabilities shown on the Annual Reports
          (Form 5500 series)  delivered  to  ProMedCo-Harrisburg  in  connection
          herewith.  No material  change with respect to the matters  covered by
          the most recent Annual Report for each Pension Plan has occurred since
          the filing date thereof.  The terms and operation of each Pension Plan
          have complied,  and are in compliance,  with the applicable provisions
          of ERISA and the Code.  All  Pension  Plans have at all times been and
          are  qualified  under  Section  401(a) of the Code,  except  for those
          Pension Plans set forth in Exhibit 3.22 of the Exhibit Volume. None of
          the Pension Plans listed in Exhibit 3.21 is unfunded.

         3.23 Employee Matters.  Included as Exhibit 3.23A of the Exhibit Volume
is a list of all employees of HealthAmerica  together with their annual rates of
compensation  and a list of all people who were paid  bonuses in the last twelve
months  plus the  amount  thereof.  No  written  employment  agreement  to which
HealthAmerica  is a  party  requires  longer  than  a  four-week  notice  before
termination,  and there is no agreement to lend,  or guarantee  any loan,  to an
employee,  or an agreement  relating to a bonus,  severance pay or similar plan,
agreement,  arrangement or understanding,  except as set forth in Exhibit 3.23B.
Exhibit  3.23C of the  Exhibit  Volume  is a  written  description  of  employee
benefits of HealthAmerica.

         3.24  Insurance and Bonds.  Exhibit 3.24A contains a description of all
fire,  liability  and  other  insurance  coverage  maintained  by  HealthAmerica
currently in force, including the amounts and losses and risks covered; all such
policies  are  fully  paid as to all  premiums  heretofore  due.  Exhibit  3.24B
contains a  description  of all  malpractice  liability  insurance  policies  of
HealthAmerica  since  January  1, 1994.  Except as set forth on  Exhibit  3.24B,
HealthAmerica  has not had in the last seven years  filed a written  application
for any  insurance  coverage  which has been  denied by an  insurance  agency or
carrier.  HealthAmerica is not in material default with respect to any provision
contained  in any such  policy  and has not failed to give any notice or present
any claim under any such policy in due and timely fashion.

         3.25 Labor Matters.  There are no collective bargaining agreements with
any labor union to which  HealthAmerica is a party or by which  HealthAmerica is
bound,  and it is not currently  negotiating with a labor union. No employees of
HealthAmerica have ever petitioned for a representation election.  HealthAmerica
is in compliance with all applicable  laws respecting  employment and employment
practices,  terms and conditions of employment  and wages and hours,  and is not
engaged  in any  unfair  labor  practice.  There  is no  unfair  labor  practice
complaint  against  HealthAmerica  pending before the National  Labor  Relations
Board. There is no labor strike, dispute,  slowdown or stoppage actually pending
or,  to  its  knowledge,  threatened  against  or  affecting  HealthAmerica.  No
grievance  which might have a material  adverse effect on  HealthAmerica  or the
conduct of its business nor any such  arbitration  proceeding  arising out of or
under collective  bargaining agreements is pending and no claim therefor exists.
HealthAmerica has not experienced any employee strikes during the


<PAGE>






last three  years.  HealthAmerica  will advise  ProMedCo-Harrisburg  of any such
labor dispute,  petition for  representative  election or negotiations  with any
labor union which shall arise before the Closing Date. Except as may be required
by ss. 4980B of the Code or applicable state health care  continuation  coverage
statutes,  HealthAmerica  has no liability  under any plan or arrangement  which
provides welfare benefits,  including medical and life insurance, to any Current
or future retiree or terminated employee.

         3.26 Third Party Payor Compliance. HealthAmerica is participating in or
otherwise  authorized to receive  reimbursement  from or is a party to Medicare,
Medicaid,  and other third-party payor programs (collectively "Third Party Payor
Programs").   All   necessary   certifications   and   contracts   required  for
participation  in such  programs  are in full force and effect and have not been
amended or  otherwise  modified,  rescinded,  revoked or assigned as of the date
hereof,  and to the best of  HealthAmerica's  knowledge,  no condition exists or
event has occurred  which in itself or with the giving of notice or the lapse of
time or both would result in the suspension,  revocation, impairment, forfeiture
or  non-renewal  of  any  such  Third  Party  Payor  Program.  To  the  best  of
HealthAmerica's  knowledge,   HealthAmerica  is  in  full  compliance  with  the
requirements of all such Third Party Payor Programs applicable thereto.

         3.27 Facility  Compliance.  The Clinic Facility is duly licensed and is
lawfully  operated in accordance with the requirements of all applicable law and
has all necessary  authorizations for the use and operation, all of which are in
full force and effect. There are no outstanding notices of deficiencies relating
to  HealthAmerica  issued by any  governmental  authority  or Third  Party Payor
Program requiring  conformity or compliance with any applicable law or condition
for participation of such  governmental  authority or Third Party Payor Program,
and  after   reasonable   and   independent   inquiry  and  due   diligence  and
investigation,  HealthAmerica  has neither received notice nor has any knowledge
or reason to believe that such  necessary  authorizations  may be revoked or not
renewed in the ordinary course.

         3.28  Improper  Payments.  Neither  HealthAmerica  nor any  officer  or
employee of  HealthAmerica  have made any bribes,  kickbacks  or other  improper
payments on behalf of  HealthAmerica or received any such payments from vendors,
suppliers or other persons contracting with HealthAmerica.

         3.29 Books of Account;  Reports.  The books of account of HealthAmerica
in reasonable  detail,  accurately and fairly reflect its  transactions  and the
disposition  of its  assets.  HealthAmerica  has filed all  reports  and returns
required  by any law or  regulation  to be filed by it for which the  failure to
file  would  have a  material  adverse  effect on the  operations  of the Clinic
Facility or the Assets.

director of  HealthAmerica  has engaged any finder or broker in connection  with
the transactions contemplated hereunder.

         3.31   Consents  and   Approvals  of   Governmental   Authorities.   No

registration  with any  governmental or regulatory  authority in connection with
the  execution  and  delivery  of this  Agreement  and the  consummation  of the

third parties are required in connection with the execution and delivery of this
Agreement by HealthAmerica and the consummation of the transactions contemplated
hereby.

         3.33 No Adverse Effect. To the best knowledge of  HealthAmerica,  there
is no event or condition of any kind or character  pertaining  to the  business,
assets or prospects of  HealthAmerica  that may adversely  affect such business,
assets or prospects other than general economic conditions  affecting the United
States.

         3.34 Disclosure.  No representations and warranties by HealthAmerica in
this Agreement and no statement in this Agreement or any document or certificate

breach of the Alliance4Health NetSource Agreement caused, or resulting from 
actions of, HealthAmerica.

         6.4  Compliance  with  Agreement.  Prior to the Closing,  HealthAmerica
shall not undertake any course of action  inconsistent  with satisfaction of the
conditions  applicable to it set forth in this Agreement,  and shall do all such
acts and take all such  measures as may be  reasonably  necessary to comply with
the  representations,  agreements,  conditions  and  other  provisions  of  this
Agreement.  Prior to the Closing,  HealthAmerica shall give  ProMedCo-Harrisburg
prompt  written  notice  of any  change  in  any  information  contained  in the
representations  and  warranties  made in Article 3 hereof  and on the  Exhibits
referred  to  therein  (provided,  however  that  such  notice  shall  not limit

which constitutes a default of any covenant or agreement made in Article 6 or in
any other section hereof.

         6.5  Necessary   Consents.   HealthAmerica  shall  take  the  necessary
corporate and other actions,  including  submitting  required notices to various

the  Assets so as to enable  ProMedCo-Harrisburg  to enjoy all of the rights now
enjoyed by HealthAmerica with respect to the Assets. Said consents shall be in a
form  acceptable  to  ProMedCo-Harrisburg  and,  if executed  with  respect to a
contract,   shall  contain  an  acknowledgment  by  the  consenting  party  that
HealthAmerica  has fully complied with and is not in default under any provision
of the particular  contract.  Nothing in this Agreement shall be construed as an
attempt  to  agree  to  assign  any  contract  which  is by law or by  agreement
nonassignable  without the consent of the other party or parties thereto,  or of
any  governmental  authority,  as the case may be,  unless such consent shall be
given.

         6.6  Unusual  Events.  Until  the  Closing  Date,  HealthAmerica  shall
supplement or amend all relevant  Exhibits in the Exhibit Volume with respect to
any matter  thereafter  arising or discovered which, if existing or known at the
date of this Agreement, would have been required to be set forth or described in
such  Exhibits;  provided,  however,  that for the  purposes  of the  rights and
obligations of the parties hereunder, any such supplemental disclosure shall not
be  deemed to have  been  disclosed  as of the date  HealthAmerica  delivers  to
ProMedCo-Harrisburg  the Exhibit Volume pursuant to ss. 9.1 of this Agreement or
any other date,  and shall not be deemed to amend or supplement  any Exhibits or
to  prevent  or cure any  misrepresentation,  breach  of  warranty  or breach of
covenant, unless agreed to in writing by ProMedCo-Harrisburg.

         6.7 Confidential Information. HealthAmerica shall keep confidential all
information provided by ProMedCo and ProMedCo-Harrisburg  regarding the business
plan,  financial  condition and operations of ProMedCo and  ProMedCo-Harrisburg,
which is not in the public domain,  and shall exercise the same care in handling
such


<PAGE>






information  as  it  would  exercise  with  similar   information  of  its  own.
HealthAmerica  may disclose  information  it deems  advisable  to its  physician
employees  provided such  physician  employees  are advised of the  confidential
nature of such  information and agree to keep such  information  confidential as
provided  herein.  ProMedCo  and  ProMedCo-Harrisburg  shall  be a  third  party
beneficiaries of such agreements.

         6.8 Interim Financial Statements.  Within 30 days after the end of each
calendar month subsequent to the date of this Agreement and prior to the Closing
Date,  HealthAmerica shall deliver to  ProMedCo-Harrisburg  an unaudited balance
sheet of  HealthAmerica  as of the end of such calendar  month together with the
related  statement of  operations.  All such financial  statements  shall fairly
present the financial  position,  results of  operations  and cash flows for the
financial periods indicated,  in accordance with generally  accepted  accounting
principles  consistently applied except that footnote information may be omitted
in such statements, and that such statements shall be subject to normal year-end
audit adjustments,  but only if such adjustments are of a normal, recurring type
and are not material in the aggregate.  So long as the Interim Service Agreement
is in full force and effect,  HealthAmerica  shall be deemed to be in compliance
with this ss. 6.8.

         6.9 Departmental Violations.  All notes or notices of violations of law
or  municipal  ordinances,  orders  or  requirements  noted in or  issued by the
departments of buildings,  fire, labor,  health, or any other state or municipal
department having  jurisdiction  against or affecting the business,  property or
assets of  HealthAmerica  shall be complied with prior to the Closing Date.  All
such notes or  notices,  after the date  hereof and prior to the  Closing  Date,
shall be complied with by HealthAmerica  prior to the Closing Date. Upon written
request,  HealthAmerica shall furnish  ProMedCo-Harrisburg with an authorization

         indemnity contained in this Article 10, stating the nature and basis of
         the claim and the amount thereof.

     (b)  In the event any claim,  action, suit or proceeding is brought against
          a party  (the  "Indemnified  Party")  with  respect to which the other
          party  (the  "Indemnifying   Party")  may  have  liability  under  the
          indemnity  contained in this Article 10, the  Indemnified  Party shall
          permit the Indemnifying  Party to assume the defense of any such claim
          or  any   litigation   resulting   from  such  claim,   provided  that
          ProMedCo-Harrisburg  shall not be required to permit  HealthAmerica to
          assume the  defense of any third  party claim which if not first paid,
          discharged, or otherwise complied with would result in an interruption
          or cessation of the conduct of the  ProMedCo-Harrisburg's  business or
          any material part thereof. Failure by the Indemnifying Party to notify
          the  Indemnified  Party of its  election  to defend  any such claim or
          action by a third party within  thirty (30) days after notice  thereof
          shall  have been  given by the  Indemnified  Party,  shall be deemed a
          waiver of any such  election.  If the  Indemnifying  Party assumes the
          defense  of  such  claim  or  litigation  resulting   therefrom,   the
          obligations of the Indemnifying Party hereunder as to such claim shall
          include  taking  all steps  reasonably  necessary  in the  defense  or
          settlement  of such claim or  litigation  resulting  in the defense or
          settlement of such claim or litigation resulting therefrom,  including
          the retention of counsel  satisfactory to the Indemnified  Party,  and
          holding the  Indemnified  Party  harmless from and against any and all
          damage resulting from, arising out of, or incurred with respect to any
          settlement


<PAGE>



         approved by the  Indemnifying  Party or any judgment in connection with
         such claim or litigation  resulting  therefrom.  The Indemnifying Party
         shall not, in the defense of such claim or  litigation,  consent to the
         entry of any judgment (other than a judgment of dismissal on the merits
         with costs) except with the written  consent of the  Indemnified  Party
         nor enter into any settlement  (except with the written  consent of the
         Indemnified  Party)  which does not  include as an  unconditional  term
         thereof the giving by the claimant or the plaintiff to the  Indemnified
         Party a  release  from  all  liability  in  respect  to such  claim  or
         litigation.

     (c)  If the  Indemnifying  Party  shall not assume the  defense of any such
          claim  by  a  third  party  or  litigation  resulting  therefrom,  the
          Indemnified  Party may defend against such claim or litigation in such
          manner as it deems  appropriate.  The  Indemnifying  Party  shall,  in
          accordance  with  the  provisions   hereof,   promptly  reimburse  the
          Indemnified Party for the amount of any settlement  reasonably entered
          into by the  Indemnified  Party  and for all  damage  incurred  by the
          Indemnified Party in connection with the defense against or settlement
          of such claim or litigation.

         10.4  Remedies  Cumulative.  The  remedies  provided  herein  shall  be
cumulative  and  shall  not  preclude  ProMedCo  and  ProMedCo-Harrisburg   from
asserting any other rights or seeking any other remedies  against  HealthAmerica
to which ProMedCo and ProMedCo-Harrisburg  are entitled by law.  Notwithstanding
the foregoing,  neither party shall have any liability  under this Article 10 in
excess  of the  Consideration  hereunder  except  for  cases  of  fraud or other
intentional  misconduct  and neither  party shall  assert any claims for matters
involving less than $5,000 in the aggregate.

         11.3 Occasional Sale.  HealthAmerica,  ProMedCo and ProMedCo-Harrisburg
believe that the transaction  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 the  Pennsylvania  Tax Code,  and,
therefore,  the  sale of any and all  items of  tangible  personal  property  to
ProMedCo-Harrisburg  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  Commonwealth  of  Pennsylvania  seeks to collect  sale or use tax under the
Pennsylvania Tax Code,  ProMedCo-Harrisburg  shall be liable and responsible for
any  such  tax.  HealthAmerica  shall  cooperate  with   ProMedCo-Harrisburg  in
connection with any audit of this  transaction  regarding the application of the
sales tax law thereto.

         11.4  Non-Assignable Property Interests.

     (a)  To the  extent  that any  lease,  contract,  permit or other  property
          interest which would otherwise  constitute a part of the Assets is not
          capable  of  being  assigned,  transferred  or  subleased  or if  such
          assignment,  transfer or sublease or attempted assignment, transfer or
          sublease would  constitute a breach thereof or a violation of any law,
          decree,  order,  regulation or other governmental edict,  neither this
          Agreement nor the Closing shall constitute an assignment,  transfer or
          sublease  thereof,  or an attempted  assignment,  transfer or sublease
          thereof.

(b)      To the  extent  that any  lease,  contract,  permit  or other  property
         interest  constituting  a part of the  Assets is not  capable  of being
         assigned,  transferred  or subleased,  from and after the Closing Date,
         and to the extent  reasonably  possible,  HealthAmerica  shall make all
         benefits    of   such    non-assignable    interests    available    to
         ProMedCo-Harrisburg    at   no    charge,    cost   or    expense    to
         ProMedCo-Harrisburg.

         11.5  Cooperation  by ProMedCo  and  ProMedCo-Harrisburg.  In the event
HealthAmerica  is required to defend  against  any  action,  suit or  proceeding
arising  out  of  a  claim   pertaining   to  the  business  or   operations  of
HealthAmerica,  ProMedCo and  ProMedCo-Harrisburg  shall provide such assistance
and cooperation,  including,  without  limitation,  witnesses and documentary or
other  evidence as may  reasonably be requested by  HealthAmerica  in connection
with its defense.

         11.6   Cooperation   by   HealthAmerica.   In  the  event  ProMedCo  or
ProMedCo-Harrisburg is required to defend against any action, suit or proceeding
arising out of a claim pertaining to a liability assumed by  ProMedCo-Harrisburg
pursuant  to  this   Agreement   relating  to  the  business  or  operations  of

                                SERVICE AGREEMENT

         Service  Agreement  ("Agreement")  dated  October 1, 1997,  between PHB
Management Company, Inc., a Pennsylvania corporation ("ProMedCo-Harrisburg") and
Beacon Medical Group, P.C. a Pennsylvania professional corporation ("BEACON").

RECITALS:

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

         The parties agree as follows:

1.  RESPONSIBILITIES OF THE PARTIES

         1.1 General Responsibilities of the Parties.  ProMedCo-Harrisburg shall
provide BEACON with offices, facilities,  equipment, supplies,  non-professional
support   personnel,   and   management   and   financial   advisory   services.
ProMedCo-Harrisburg  shall neither  exercise control over nor interfere with the
physician-patient  relationship,  which shall be maintained strictly between the
physicians of BEACON and their patients.

         1.2  BEACON's  Matters.  BEACON  shall  maintain  sole  discretion  and
authority over the financial  matters  relative to its corporate  existence.  It
shall  set  compensation  levels  for  BEACON  Employees.  BEACON  will  also be
responsible  for all other  matters  pertaining  to the  operation of BEACON not
otherwise assumed by ProMedCo-Harrisburg under the terms of this Agreement.

         1.3 Patient Referrals. The parties agree that the benefits to BEACON 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-Harrisburg  to any of  BEACON's  patients  in any
facility or laboratory controlled, managed or operated by ProMedCo-Harrisburg.

2.  POLICY COUNCIL

         2.1  Formation and Operation of the Policy  Council.  A Policy  Council
will be established which shall be responsible for the major policies which will
serve as the basis for  operations  of the  Clinic.  The  Policy  Council  shall
consist  of six  members.  ProMedCo-Harrisburg  shall  designate,  at  its  sole
discretion,  three members of the Policy Council.  Members of the Policy Council
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 and the
most senior  member of the group of designees of Pro  MedCo-Harrisburg  shall be
deemed to hold the proxy of any  designee of  ProMedCo-Harrisburg  who is absent
from the meeting.  BEACON at its sole discretion  shall designate three members.
Except as may otherwise be provided, the act of a majority of the members of the
Policy Council shall be the act of the Policy Council.

         2.2 Duties and Responsibilities of the Policy Council.  During the term
of this  Agreement,  the  Policy  Council  shall have the  following  duties and
responsibilities.

         (a)      Annual  Budgets.  All annual  capital  and  operating  budgets
                  prepared by ProMedCo-Harrisburg, as set forth in Section 3 and
                  employing  ProMedCo-Harrisburg's financial expertise, shall be
                  subject  to the  review and  approval  of the Policy  Council,
                  provided;   however,   ProMedCo-Harrisburg  shall  have  final
                  approval of any capital expenditure required by BEACON.

     (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 BEACON  is  dissatisfied  with the  services
          provided by the  Administrator,  BEACON  shall refer the matter to the
          Policy Council.  ProMedCo-Harrisburg  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-Harrisburg
          shall have the ultimate authority to terminate the Administrator.

         (c)      Advertising. All advertising,  marketing, and public relations
                  shall be  subject  to the prior  review  and  approval  of the
                  Policy  Council,   in  compliance  with  applicable  laws  and
                  regulations   governing   professional   advertising   and  in
                  accordance  with  the  standards  and  medical  ethics  of the
                  American  Medical  Association  and the  Pennsylvania  Medical
                  Society.

         (d)      Ancillary  Services.  The Policy  Council shall approve Clinic
                  provided ancillary services based upon the pricing,  access to
                  and quality of such services.

         (e)      Capital  Improvements and Expansion.  The Policy Council shall
                  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,

                  any capital expenditures.

         (f)      Exceptions  to Inclusion in the Net Revenue  Calculation.  The
                  exclusion of any revenue from Net Clinic Revenues, whether now
                  or in the  future,  shall be  subject to the  approval  of the
                  Policy Council.

         (g)      Grievance Issues.  Subject to the provisions of Section 1.2 of
                  this  Agreement,  the Policy  Council shall  consider and make
                  final decisions regarding grievances pertaining to matters not
                  specifically  addressed in this Agreement as referred to it by
                  BEACON's Board or ProMedCo-Harrisburg.

         (h)      Patient    Fees.    In    consultation    with    BEACON   and
                  ProMedCo-Harrisburg, the Policy Council shall review and adopt

                  rendered by the Clinic.

                  analysis provided by ProMedCo-Harrisburg,  shall determine the
                  number  and  type of  physicians  required  for the  efficient
                  operation  of  the  Clinic  and  BEACON  shall  determine  the
                  individual physicians to be hired to fill such positions.  The
                  approval  of  ProMedCo-Harrisburg  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  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-Harrisburg  and BEACON 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 BEACON.

     (k)  Strategic  Planning.  The  Policy  Council,  with  the  assistance  of

accordance with policies  approved by the Policy Council,  and including without
limitation,  performance  of some  functions at locations  other than the Clinic

a  businesslike  manner.  BEACON,  through  BEACON  Employees,  will provide all
medical  services.  ProMedCo-Harrisburg  will  have no  authority,  directly  or

brought to acceptable  levels through  counsel and  assistance,  or whether such

regarding  staff  shall be  governed  by the  overriding  principle  and goal of

a cost effective manner.

         3.1.7 Managed Care Contracting. ProMedCo-Harrisburg will be responsible
for  marketing,  negotiation,  and  administering  all managed  care  contracts,
subject to the  provisions  of Section  2.20);  provided,  however,  except with
respect to the existing  relationship with  AllianceHealth  NetSource,  Inc., no
contract or  arrangement  regarding the provision of clinical  services shall be
entered into without BEACON's  consent.  The parties agree that in the event the
Policy  Council  determines to pursue the formation of an IPA,  other  physician
organization  or hospital  network,  or enter into risk  assumption  contractual
arrangements,  the parties  will  structure  the IPA,  hospital  network or such
arrangements  in the  manner  in which  the  Policy  Council  determines  unless
otherwise specifically addressed in this Agreement. The IPA or hospital

                                                         5

<PAGE>



network   will  be   managed  by   ProMedCo-Harrisburg   or  an   affiliate   of
ProMedCo-Harrisburg. In the event a management agreement is entered into for the
management of an IPA or hospital network,  the management agreement will provide
for a management fee to be paid to the management  organization by the IPA. Such
management  fee shall be  approved  by the Policy  Council and set at a level to
cover the costs of the management agreement.

         3.1.8 Billing and Collections.  ProMedCo-Harrisburg shall bill patients
and  collect  all fees for  services  performed  inside or  outside  the  Clinic
Facility or arrange for such  billing and  collection.  BEACON  hereby  appoints
ProMedCo-Harrisburg,   for  the  term   hereof,   to  be  its  true  and  lawful
Attorney-in-fact  for the  following  purposes (i) to bill  patients in BEACON's
name and on its behalf, (ii) to collect accounts receivable  resulting from such
billing in BEACON'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 BEACON (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 BEACON to collect any accounts and monies owed
to the Clinic,  to enforce the rights of BEACON or BEACON  Employees as creditor
under any contract or in connection  with the  rendering of any service,  and to
contest   adjustments   and  denials   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-Harrisburg'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 BEACON shall
be the owner  ("Account").  ProMedCo-Harrisburg  and BEACON shall maintain their
accounting  records in such a way as to clearly  segregate  Net Clinic  Revenues
from other  funds of  ProMedCo-Harrisburg  or  BEACON.  BEACON  hereby  appoints
ProMedCo-Harrisburg  as its true and lawful  attorney-in-fact  to deposit in the
Account all revenues  collected.  BEACON  covenants,  and shall cause all BEACON
Employees to  covenant,  to forward any  payments  received  with respect to Net
Clinic  Revenues  for  services  provided  by BEACON  and  BEACON  Employees  to
ProMedCo-Harrisburg  for  deposit.  ProMedCo-Harrisburg  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-Harrisburg
("ProMedCo-Harrisburg Account"). BEACON and ProMedCo-Harrisburg hereby agree

                                                         6

<PAGE>






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 BEACON that  interferes  with the operation of this
Section,  including,  but  not  limited  to,  any  failure  to  deposit  or have
ProMedCo-Harrisburg  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-Harrisburg,  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 BEACON and the BEACON Employees;

     (b)  To receive payments from patients,  third party payor plans, insurance
          companies,  Medicare,  Medicaid  and all other  payors with respect to
          services rendered by BEACON and its BEACON Employees;

     (c)  To take  possession  of and endorse any notes,  checks,  money orders,
          insurance  payments and any other  instruments  received as payment of
          such accounts receivable; and

     (d)  To collect all revenues of the Clinic.

         3.1.10     Management     Information     Systems/Computer     Systems.
ProMedCo-Harrisburg  shall  supervise and provide  information  systems that are
necessary and appropriate for the operation of the Clinic.

         3.1.11 Legal and Accounting Services. ProMedCo-Harrisburg shall arrange
for or render to BEACON such business and financial management  consultation and
advice as may be reasonably required or requested by BEACON and directly related
to the operations of the Clinic,  including the attorneys'  fees and other costs
of  enforcing  any  physician  contract  containing  restrictive  covenants  and
attorneys' fees and other costs and expenses of litigation, arbitration or other
proceeding  for  malpractice  suits against the Clinic and the BEACON  Employees
other  than the  Physician  Shareholders  to the  extent  such  fees,  costs and
expenses are not covered by insurance;  provided, such services must be approved
in advance  by the  Administrator  and shall be paid by BEACON and  treated as a
Clinic Expense.  ProMedCo-Harrisburg  shall not be responsible for rendering any
legal or tax advice or

                                                         7

services or personal financial services to BEACON or any employee or agent of
BEACON.

procedures.

7.  FINANCIAL ARRANGEMENTS

         7.1   Payments   to  BEACON   and   ProMedCo-Harrisburg.   BEACON   and

against any liability,  loss, damages,  claims,  causes of action and reasonable

previous   month.   Although  it  is  the   intention   of  the   parties   that
ProMedCo-Harrisburg purchase and thereby become owner of the accounts receivable
of BEACON, in case such purchase shall be ineffective for any reason, BEACON, as
of the  Effective  Date of this  Agreement,  grants and shall cause each Medical
Professional  to  grant  to  ProMedCo-Harrisburg  a first  priority  lien on and
security  interest  in and to any and all  interest  of BEACON and such  Medical

BEACON and the Medical  Professionals  Employees or otherwise  generated through
the operations of the Clinic,  and all proceeds with respect thereto,  to secure
the payment to  ProMedCo-Harrisburg  of all such accounts  receivable,  and this

give  effect  to  the  foregoing.  In  addition,  BEACON  shall  cooperate  with
ProMedCo-Harrisburg and execute and deliver, and cause each Medical Professional
to execute and deliver, all necessary documents in connection with the pledge of
such accounts  receivable  to  ProMedCo-Harrisburg  or at  ProMedCo-Harrisburg's
option,  its lenders.  All  collections  in respect of such accounts  receivable

9.  RESTRICTIVE COVENANTS AND LIQUIDATED DAMAGES

         The   parties   recognize   that  the   services   to  be  provided  by

practice to which the physicians  associated  with BEACON devote their full time
and attention. To that end:

         9.1 Restrictive Covenants by BEACON. During the term of this Agreement,
except as approved by the Policy  Council  pursuant  to Section  2.2(e)  hereof,
BEACON 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 BEACON pursuant to this Agreement anywhere within a
radius of 15 miles of the Clinic Facility, or within a radius of 15 miles of any
current or future  medical  office,  clinic or other health care  facility  from
which BEACON provides medical services.

         9.2 Restrictive Covenants By Medical Professionals. BEACON shall obtain
and  enforce  formal  employment  agreements  from  each of its  future  Medical
Professionals in  substantially  the form attached as Appendix 2.9C to the Asset

                                                        14

<PAGE>






during the term of such Medical Professional's  employment agreement,  and for a
period of two years  after any  termination  of  employment  with  BEACON,  such
Medical  Professional will not 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 BEACON pursuant to this Agreement  within a radius of 15 miles of any medical
office,  clinic or other health care facility operated by BEACON from which such
Medical  Professional  had provided  medical  services within 24 months prior to
such termination and that  ProMedCo-Harrisburg  shall have third-party rights to
enforce  such  agreements.  BEACON  shall also  ensure  that any of its  current
Medical Professionals whose employment agreements are extended beyond an initial
five year term are subject to the  provisions  set forth in this  paragraph  for
such extension.

         9.3    Physician Shareholder and Physician Employee Liquidated Damages.

     (a)  Release  from  Restrictive   Covenants.   The  restrictive   covenants
          described  in Section  9.2 of this  Agreement  will  provide  that the
          Medical Professionals  (existing Medical Professionals with respect to
          renewal terms thereof,  and future Medical  Professionals with respect
          to the initial and renewal  terms  thereof) may be released  from such
          restrictive  covenants by paying  Liquidated  Damages in the amount of
          $20,000.

     (b)  Repayment  of  Consideration  in Certain  Events.  In  addition,  if a
          Medical Professional received a $20,000 payment pursuant to the Beacon
          Inducement   Agreement  to  terminate  his  or  her  employment   with
          HealthArnerica  and said Medical  Professional  terminates  his or her
          employment  agreement  with BEACON for any reason (other than death or
          Total Disability as defined in the employment  agreement  between such
          Medical Professional and BEACON) prior to the fifth anniversary of the
          Closing  under the Asset  Purchase  Agreement,  or is  terminated  for
          cause, as that term is defined in such employment agreement, by BEACON
          prior to the fifth anniversary of the Closing under the Asset Purchase
          Agreement,   then  the  Medical  Professional  shall  be  required  to
          reimburse back to ProMedCo-Harrisburg such $20,000. Such payment shall
          be passed on to  ProMedCo-Harrisburg by BEACON simultaneously with the
          payment thereof by the Medical  Professional  to BEACON.  All payments
          made to  ProMedCo-Harrisburg  under  this  clause  (b)  shall be first
          applied  to  all  costs   incurred  by   ProMedCo-Harrisburg   in  the
          enforcement  of the employment  agreement for that  departing  Medical
          Professional and in recruiting a replacement Medical  Professional for
          that departing  Medical  Professional.  The  remainder,  if any, shall
          become an  additional  service  fee to be paid to  ProMedCo-Harrisburg
          pursuant to Section 7. The accounting treatment of such funds shall be
          consistently applied and

                                                        15

<PAGE>



                  approved by ProMedCo-Harrisburg's independent certified public
                  accountants and the Policy Council.

         9.4 Enforcement.  ProMedCo-Harrisburg  and BEACON 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
