                         DEFINED CARE PARTNER AGREEMENT


     This DEFINED CARE PARTNER AGREEMENT is entered into effective as of January
5,  1996  (the  "Effective  Date")  among  AmHS  Purchasing  Partners,  L.P.,  a
California limited partnership ("AmHSPP"), Mariner Health Care, Inc., a Delaware
corporation (the "Partner"),  and, solely with respect to Article 3, Section 4.1
and Article 8 hereof, Mariner Health Group, Inc., a Delaware corporation and the
parent  company of the Partner (the  "Parent"),  with reference to the following
facts:

     A.  AmHSPP  and the  Partner  desire to create a  strategic  alliance  (the
"Association"),  on the terms set forth  herein,  pursuant  to which the Partner
will be the AmHSPP-recommended resource to assist the hospitals and other health
facilities  which   participate  in  AmHSPP's  group  purchasing   program  (the
"Facilities")  in developing  subacute care,  post acute care and other mutually
agreed  upon  services  and  resources  from among  those  listed on  Appendix 1
attached hereto (collectively, "Defined Care").

     B. Primary goals for the Association are as follows:

        (1) To establish the Partner as a flexible  resource for the  Facilities
     with the ability, through a variety of potential relationships (e.g., joint
     ventures,   subcontracting  services,  co-development  of  new  facilities,
     co-investment, etc.), to meet the Defined Care needs of each Facility; and

        (2)  To  develop   Defined  Care  outcome   databases  for  use  by  the
     participants in the Association as set forth herein.

     NOW, THEREFORE,  based upon the foregoing premises and the mutual covenants
herein set forth,  the parties,  intending to be legally bound,  hereby agree as
follows:

                                    ARTICLE 1

                        CONTRIBUTIONS TO THE ASSOCIATION

     1.1 AmHSPP/Facilities.

     a. Access.  AmHSPP will (1) represent the Partner to the  Facilities as the
AmHSPP-selected  and  endorsed  resource  for  Defined  Care and (2) promote the
establishment of business relationships among the Partner and the Facilities for
the use of resources to assist the  Facilities  in  developing  or arranging for
Defined Care (with resulting  agreements  between the Partner and the Facilities
being herein referred to as the "Facility Agreements").




         b.  Consultant's   Services.  For  interested  Facilities  electing  to
participate in the Association,  AmHSPP will make arrangements for the retention
of a consultant (the  "Consultant") with expertise in post acute care strategies
and development to assist the Partner and such Facilities in developing mutually
satisfactory  relationships.  AmHSPP's  arrangements with the Consultant are not
intended to obligate the  Partner;  rather,  it is the  intention of the parties
that the Partner will compensate the Consultant only in those  situations  where
the Partner makes  arrangements  with the Consultant and/or any Facility(ies) to
such effect.

         c. Exclusivity.  During the Term (defined below), AmHSPP will not enter
into a  national  agreement  with any  entity,  other  than the  Partner  or its
affiliates, to provide or to arrange to provide to the Facilities those services
described  in items 1, 2, 3 and 7 of the first group of items listed on Appendix
1 attached hereto (the "Exclusive Defined Care").

     1.2 Partner.

         a.  Performance  Standards.  The  parties  expect  that  each  Facility
Agreement will address the scope,  terms and conditions of the Partner's Defined
Care relationship with the respective Facility, as well as performance standards
for the Partner's services;  however, in all instances the Partner's performance
will meet or exceed all applicable  state and federal  standards with respect to
the  provision of Defined Care and the  maintenance  of related  facilities  and
resources.

         b. Efforts.

            i.  Negotiation  with  Facilities.  The Partner  will  exercise  its
commercially reasonable best efforts to negotiate a mutually acceptable Facility
Agreement with each Facility  indicating an interest in working with the Partner
as a Defined  Care  resource.  Such  commercially  reasonable  best efforts will
include,  without  limitation,  the Partner (x)  offering to each  Facility  the
elements set forth on Appendix 2 attached hereto (titled  "Guiding  Principles")
and (y) making Defined Care available to each interested  Facility on such terms
and conditions as the Partner and the Facility may agree.

            ii. Terms of Facility Agreements. Without limiting the provisions of
Sections 1.2(a) and 1.2(b)(i) above, the Partner agrees that, at the election of
any  Facility,  it will  negotiate the terms of a Facility  Agreement  with such
Facility  with  reference  to the  elements  for a joint  venture or  management
services arrangement as set forth on Appendix 3 attached hereto.

            iii. Market Analysis. At the request of any Facility,  and without a
charge or  obligating  the  Facility in any way,  the Partner  will provide such
Facility  with a preliminary  

                                       2

analysis  regarding the Defined Care market within such Facility's Territory 
(defined below).

         c. Exclusivity.

            i. Statement of Intent. It is the agreement of the parties that each
of  the  Facilities  will  have a  right  of  first  opportunity,  within  their
respective geographical territories (each, a "Territory"),  to have an exclusive
Facility Agreement for Exclusive Defined Care. However,  the parties acknowledge
the  following:  (1) since  each  Facility  may  determine  not to enter  into a
Facility Agreement,  the Partner should thereafter have the ability to work with
other parties in such a Facility's  Territory;  (2) future  acquisitions  by the
Partner  and/or  its  affiliates  (a  "Partner  Acquisition")  could  result  in
situations where the Partner and/or its affiliates are working,  in Territories,
with parties other than  Facilities  ("Outside  Relationships");  and (3) future
acquisitions by APS Healthcare, Inc., an affiliate of AmHSPP ("APS"), and/or the
affiliates  of  APS  (an  "APS  Acquisition")   could  also  result  in  Outside
Relationships  despite the desire of affected  Facilities to enter into Facility
Agreements.

            ii. National  Agreement.  Notwithstanding  any Partner  Acquisition,
during the Term the Partner will not enter into, or otherwise maintain, directly
or  indirectly,  an agreement  to provide  Exclusive  Defined Care  resources or
services  to the  facilities  of any  national  alliance  of  hospital-based  or
hospital dominated health systems (other than APS and its affiliates).

            iii. Negotiations with each Facility.

                  (1) Formal  Contact.  If the  Partner  and/or  its  affiliates
determine  to enter a  Facility's  Territory,  the  Partner  will  exercise  its
commercially reasonable best efforts to negotiate a mutually acceptable Facility
Agreement with such Facility. The Partner will commence its efforts with respect
to each Facility by formally contacting the Facility in writing and inquiring as
to  the  Facility's  interest  regarding  discussion/negotiation  of a  Facility
Agreement.  The  Partner  will  advise  AmHSPP  in  writing  promptly  upon  the
initiation  of any formal  contact by the  Partner  or its  affiliates  with any
Facility.

                  (2) Facility Response and Discussion. If the Facility fails to
respond  in  writing,  within  thirty  (30)  days of the date of the  Facility's
receipt of such Partner's formal contact, that it is so interested (e.g., with a
letter of  interest  from such  Facility to the  Partner),  then the Partner may
enter into  arrangements for Exclusive  Defined Care with parties other than the
Facility.  If the Facility  does respond in writing  within such thirty (30) day
period that it is interested in pursuing such discussion/negotiation (e.g., with
a  letter  of  interest),  then  the  Partner  will  exercise  its  commer-

                                       3

cially  reasonable  best  efforts,  for a period of sixty  (60)  days  following
receipt of such response,  to negotiate a Facility  Agreement (with reference to
the provisions of Section 1.2(b) above and which  efforts,  without  limitation,
shall be exclusive  within the  Facility's  Territory  during such period).  If,
after such sixty (60) day period, the Facility and the Partner have not achieved
an understanding  regarding the material terms of a mutually acceptable Facility
Agreement (with the existence of such an  understanding  to be ascertained,  for
example,  by the existence of a non-binding letter of intent between the Partner
and the Facility),  then the Partner may enter into  arrangements  for Exclusive
Defined Care with parties other than the Facility.

                  (3) Items of Exclusivity.  Following compliance by the Partner
with the  provisions of the foregoing  paragraph (2), if the material terms of a
mutually  acceptable  Facility  Agreement  involve  less  than  all  "items"  of
Exclusive  Defined  Care (with  reference  to the items set forth on  Appendix 1
attached  hereto),  then the Partner may enter into  arrangements  for Exclusive
Defined Care with parties  other than the Facility  with respect to the excluded
items;  however,  for those items of Exclusive  Defined Care which are or become
the  subject of a Facility  Agreement,  such  Facility  Agreement  with  respect
thereto  shall  be  the  Partner's  exclusive  arrangement  within  the  subject
Facility's Territory (subject to the provisions of paragraph (vii) below).

            iv. Partner Acquisitions. If (i) a Partner Acquisition results in an
Outside  Relationship,  (ii) any affected Facility  indicates that it desires to
enter into a Facility  Agreement and (iii) the terms of such  proposed  Facility
Agreement are commercially  reasonable,  then the Partner will,  consistent with
its contractual obligations with respect to such Outside Relationship,  exercise
its commercially  reasonable best efforts to terminate the Outside  Relationship
and thereafter establish the proposed Facility Agreement.

            v. APS Acquisitions. If (i) an APS Acquisition results in an Outside
Relationship, (ii) any affected Facility indicates that it desires to enter into
a Facility  Agreement,  and (iii) the terms of such proposed Facility  Agreement
are commercially  reasonable,  then the Partner may (at its option),  consistent
with its  contractual  obligations  with respect to such  Outside  Relationship,
exercise its  commercially  reasonable  best  efforts to  terminate  the Outside
Relationship and thereafter establish the proposed Facility Agreement.  However,
if the Outside Relationship should terminate for any reason, then, at such time,
the affected  Facility will have a right of first opportunity (with reference to
the  provisions of paragraphs (i) and (iii) above) and the Partner will exercise
its commercially  reasonable best efforts to establish a Facility Agreement with
such Facility (with reference to the provisions of paragraph (iii) above).

                                       4

            vi. Partner's Existing  Arrangements.  The agreements  undertaken by
the  Partner  prior to the date  hereof and  identified  on  Appendix 4 attached
hereto,  as well as agreements  which may result from current  discussions  with
parties  regarding the provision of Defined Care in  territories  which are also
identified on such Appendix 4 (collectively, "Outside Agreements"), shall not be
deemed a breach of the Partner's  obligations under this Section 1.2;  provided,
however, that if any Outside Agreement should terminate for any reason, then, at
such time,  any Facility  with a Territory  affected by such  Outside  Agreement
shall have a right of first  opportunity  (with  reference to the  provisions of
paragraphs  (i) and (iii) above) and the Partner will exercise its  commercially
reasonable  best efforts to establish a Facility  Agreement  with such  Facility
(with reference to the provisions of paragraph (iii) above).

            viii.  Local  Arrangements.  This Section 1.2 shall not be deemed to
prevent  any  Facility  from  agreeing  with  the  Partner  to  separate  and/or
alternative  exclusivity  provisions in a Facility Agreement (e.g.,  exclusivity
for items of Defined Care in addition to Exclusive Defined Care).

     1.3  Association  Staff/Cost  Sharing.  An  employee  of APS,  AmHSPP or an
affiliate  of AmHSPP (the  selection  of whom shall be subject to the consent of
the Partner,  which consent shall not be unreasonably withheld or delayed) shall
be  designated  to  work  on  behalf  of  the  Facilities  with  respect  to the
Association  (referred to herein as the  "Association  Staff").  The Association
Staff shall (i) have a broad base of  experience  with  respect to the  subacute
care  industry,  (ii) be dedicated to subacute  care issues within the employing
entity and/or its affiliates and (iii) be subject to the employment,  travel and
other policies of the employing entity, and such entity shall also determine the
compensation  and  benefits  for the  Association  Staff.  The Partner  will pay
[CONFIDENTIAL  TREATMENT REQUESTED] per year (to be paid [CONFIDENTIAL TREATMENT
REQUESTED] per calendar  quarter,  in advance) to the employing  entity to cover
the costs and expenses associated with the Association Staff; provided, however,
that the Partner may, in its reasonable discretion,  advise the employing entity
of any material problem  regarding the performance of the Association Staff and,
if such  problem is not  substantially  cured  within sixty (60) days after such
notice,  then the  Partner  may suspend  such  payments  until such time as such
problem is substantially  resolved (or new Association Staff has been designated
with such new Association  Staff meeting the  requirements of this Section 1.3).
Office  space and  related  costs for  Association  Staff  shall be borne by the
hosting  entity(ies)  (i.e.,  APS,  AmHSPP,  the  Partner  and/or  participating
Facilities).

                         REPRESENTATIONS AND WARRANTIES

     4.1 Parent and  Partner.  The Parent and the  Partner  each  represent  and
warrant to AmHSPP that, as of the Effective Date:

         a. Corporate Organization and Qualification. Each of the Parent and the
Partner is a corporation  duly organized,  validly existing and in good standing
under the laws of the State of  Delaware  and is in good  standing  as a foreign
corporation in each jurisdiction where the properties owned, leased or operated,
or the  business  conducted,  by it require such  qualification  except for such
failure to so qualify or to be in such good standing, which, when taken together
with all other such  failures,  would not have a material  adverse effect on the
financial condition, properties, business or results of operations of the Parent
and its  subsidiaries,  taken as a whole (a "Parent Material  Adverse  Effect").
Each of the  Parent  and the  Partner  has the  requisite  corporate  power  and
authority to carry on its business as it is now being conducted.  The Parent has
provided AmHSPP with a complete and correct copy of the Parent's  Certificate of
Incorporation  and  By-laws,  each as


                                       6
 

amended  to date and each of which, as so provided, is in full force and effect.

         b.  Corporate  Authority.  Each of the Parent and the  Partner  has the
requisite  corporate  power and  authority  and has taken all  corporate  action
necessary in order to execute and deliver this  Agreement  (and, in the instance
of the Parent,  the Warrants) and to consummate  the  transactions  contemplated
hereby.  Except  as  may  be  limited  by  applicable  bankruptcy,   insolvency,
reorganization,  moratorium  and similar laws  affecting  creditors'  rights and
remedies  generally  and general  principles  of equity and the  discretion of a
court in  granting  equitable  remedies  (whether  validity,  binding  effect or
enforceability  is  considered  in a proceeding  at law or in equity),  (i) this
Agreement  is a valid  and  binding  agreement  of each  of the  Parent  and the
Partner,  enforceable  against the Parent and the Partner in accordance with its
terms and (ii) the Warrants are the valid and binding  agreements  of the Parent
enforceable against the Parent in accordance with their terms.

         c. Governmental Filings; No Violations.

             i. Other than (i) the filing and approval of an application for the
listing of the shares of Common Stock issuable upon any exercise of the Warrants
on the Nasdaq  National  Market,  (ii) those  notices,  disclosures  and similar
regulatory filings which the Partner intends to make, if necessary or advisable,
in the normal course of its affairs,  (iii) those  notices and filings  required
pursuant to applicable  state securities or "Blue Sky" laws and (iv) any filings
and/or approvals or clearances  required under the  Hart-Scott-Rodino  Antitrust
Improvements  Act of 1976,  as amended (the "HSR Act"),  no notices,  reports or
other  filings are required to be made by either the Parent or the Partner with,
nor  are  any  consents,   registrations,   approvals,  clearances,  permits  or
authorizations required to be obtained by either the Parent or the Partner from,
any governmental or regulatory  authority,  agency,  commission or other entity,
domestic or foreign  ("Governmental  Entity"),  in connection with the execution
and  delivery  of this  Agreement  by either the Parent or the  Partner  and the
consummation  by the Parent and the  Partner  of the  transactions  contemplated
hereby  (including,  without  limitation,  the  issuance of the  Warrants by the
Parent),  the  failure  to make or  obtain  any or all of which  could  prevent,
materially  delay or materially  burden the  transactions  contemplated  by this
Agreement.

             ii. The execution and delivery of this  Agreement by the Parent and
the Partner do not, and the consummation of the transactions contemplated hereby
by the Parent and the Partner will not,  constitute or result in (1) a breach or
violation of, or a default under,  the Parent's or the Partner's  Certificate of
Incorporation or By-Laws,  or (2) assuming  compliance with the matters referred
to in the foregoing


                                       7
 

paragraph (i), a breach or violation of, a default under, the acceleration of or
the creation of a lien, pledge, security interest or other encumbrance on assets
(with or  without  the giving of notice or the lapse of time)  pursuant  to, any
provision  of  any  agreement,  lease,  contract,  note,  mortgage,   indenture,
arrangement  or other  obligation (a "Contract") of the Parent or the Partner or
any law,  ordinance,  rule or regulation or judgment,  decree,  order,  award or
governmental  or  non-governmental  permit or license to which the Parent or the
Partner is subject,  except, in the case of clause (2) above, for such breaches,
violations, defaults or accelerations that, alone or in the aggregate, could not
prevent,  materially delay or materially burden the transactions contemplated by
this Agreement.

         d. Capital Structure.

             i. As of the close of business on January 2, 1996,  the  authorized
capital  stock of the Parent  consisted  of (i)  1,000,000  shares of  preferred
stock, par value $.01 per share, of which 500,000 shares have been designated as
"Series A Junior Participating Preferred Stock," although no shares of preferred
stock were issued and  outstanding  or held in the  treasury of the Parent,  and
(ii) 50,000,000  shares of Common Stock, of which 26,326,904  shares were issued
and outstanding and no shares were held in the treasury of the Parent. As of the

the  Parent's  various  stock plans (the  "Parent  Plans") an aggregate of up to
4,516,590  shares of Common  Stock,  subject to an increase on January 1 of each
year (after  1996) by an amount equal to two percent (2%) of the total number of
shares of Common Stock  outstanding  on December 31 of the preceding  year,  (b)
approximately  79,000  shares of Common Stock in  connection  with a transaction
currently  being  negotiated  by the  Parent  or its  affiliates,  (c) under the
Warrants an  aggregate  of  2,100,000  shares of Common  Stock and (d) under the

the Parent and State Street Bank & Trust Company an aggregate of 500,000  shares
of Series A Junior  Participating  Preferred Stock issuable upon the exercise of
rights distributed to the Parent's stockholders pursuant to the Rights Agreement
(the  "Rights"),  subject to adjustment from time to time in accordance with the
terms of the Rights Agreement. Except for outstanding options to purchase shares
of Common Stock under the Parent Plans and the Rights, and as otherwise provided
in the immediately preceding sentence of this Section 4.1(d)(i), as of the close
of  business  on January 2, 1996 there were no  outstanding  options,  warrants,
calls, rights, commitments or agreements to which the Parent or the Partner is a
party or by which  either the  Parent or the  Partner  is bound  obligating  the
Parent or the  Partner  to (x) issue,  deliver  or sell,  or cause to be issued,
delivered  or sold,  additional  shares of  capital  stock of the  Parent or (y)
grant, extend or enter into any such option, warrant, call, right, commitment or
agreement.

                                      8


             ii. All  outstanding  shares of Common  Stock are duly  authorized,
validly issued, fully paid and nonassessable,  and are not subject to preemptive
rights.  The shares of Common Stock  issuable  upon any exercise of the Warrants
have been duly authorized  and, when issued and sold after an exercise  therefor
pursuant to the terms of the Warrants,  will be validly  issued,  fully paid and
nonassessable and will not be subject to preemptive rights.

             iii.  All issued  and  outstanding  shares of capital  stock of the
Partner are owned by the Parent, and there are no outstanding options, warrants,
calls, rights, commitments or agreements to which the Parent or the Partner is a
party or by which  either the  Parent or the  Partner  is bound  obligating  the
Parent or the  Partner  to (x) issue,  deliver  or sell,  or cause to be issued,
delivered or sold,  shares of capital stock of the Partner or (y) grant,  extend
or enter into any such option, warrant, call, right, commitment or agreement.

         e. Parent Reports.

             i. The  Parent has  previously  furnished  to AmHSPP  copies of the
following  Parent  documents:  (i) its annual report on Form 10-K for the fiscal
year ended  December 31,  1994,  as amended on May 1, 1995 and October 30, 1995;
(ii) its quarterly  reports on Form 10-Q for the fiscal quarters ended March 31,
1995 (as  amended on May 25,  1995),  June 30,  1995 (as  amended on October 30,
1995) and September 30, 1995;  (iii) its current  reports on Form 8-K dated July
1, 1994 (as amended on August 12, 1994 and March 16,  1995),  September 26, 1994

1995),  October  3, 1994 (as  amended  on March 16,  1995),  October 2, 1995 (as
amended on November 22, 1995 and  December 14, 1995) and October 31, 1995;  (iv)
the description of the Rights  contained in its  registration  statement on Form

Securities  Exchange  Act of 1934,  as  amended,  since  December  31,  1994 and
publicly  available  prior to the  Effective  Date,  all in the form  (including
exhibits) so filed (collectively,  the "Parent Reports"). As of their respective
dates  (which  shall  mean the date of the last  amendment  of each such  Parent
Report which has been  amended),  the Parent  Reports did not contain any untrue
statement  of a material  fact or omit to state a material  fact  required to be
stated  therein or necessary  to make the  statements  therein,  in light of the
circumstances  under which they were made, not  misleading;  provided,  however,
that,  notwithstanding  anything to the contrary in this  Agreement,  the Parent
makes no representations or warranties regarding its proxy statement dated March
16, 1995 (as supplemented on April 1, 1995).


                                       9

 
            ii. Each of the financial  statements of the Parent included in the
Parent  Reports  has  been  prepared  in  accordance  with  generally   accepted
accounting  principles applied on a consistent basis (except as may be indicated
therein or in the notes thereto) and fairly presents the consolidated  financial
position of the Parent and its  subsidiaries as of its date or the  consolidated
results of operations, stockholders' equity or cash flows, as is appropriate, of
the Parent and its subsidiaries for the periods then ended (subject, in the case
of unaudited interim financial statements,  to normal year-end audit adjustments
and any other adjustments described therein).

         f.  Absence of Certain  Changes or Events.  Except as  disclosed in the
Parent Reports filed with the SEC and publicly  available prior to the Effective
Date,  since September 30, 1995 the Parent and its  subsidiaries  have conducted
their  businesses  only in the ordinary  course,  and there has not been (i) any
material  adverse  change in the assets,  liabilities,  financial  condition  or
operating results of the Parent from that reflected in the most recent financial
statements filed with the SEC as part of a Parent Report and publicly  available
prior to the Effective Date, (ii) any  declaration,  setting aside or payment of
any dividend or other  distribution  (whether in cash,  stock or property)  with
respect to any of the Parent's capital stock (except for the distribution of the
Rights), (iii) any split,  combination or reclassification of any of its capital
stock  or  any  issuance  or the  authorization  of any  issuance  of any  other
securities  in  respect  of,  in lieu of or in  substitution  for  shares of the
Parent's  capital stock (except for the  distribution  of the Rights),  (iv) any
damage,  destruction or loss,  whether or not covered by insurance,  which would
have a Parent Material  Adverse Effect or (v) any change in accounting  methods,
principles  or  practices  by  the  Parent  materially   affecting  its  assets,
liabilities or business, except insofar as may have been required by a change in
generally accepted accounting principles.

         g. Brokers and Finders.  Neither the Parent nor the Partner, nor any of
their respective officers, directors,  affiliates or employees, has employed any
broker or finder or incurred any liability for any brokerage  fees,  commissions
or finders' fees in connection with the transactions contemplated hereby.

         h.  Information.  This  Agreement  together with the Parent Reports and
other information disclosed by the Partner to AmHSPP, taken as a whole, does not
contain an untrue statement of a material fact made by the Parent or the Partner
or omit to state a material fact  necessary to make the statements by the Parent
or the Partner herein and therein,  in light of the  circumstances in which they
were made, not misleading.

         4.2 AmHSPP.  AmHSPP  represents  and warrants to each of the Parent and
the Partner that, as of the Effective Date:


                                       10

            a. Organization and Qualification.  AmHSPP is a limited  partnership
duly  organized,  validly  existing and in good  standing  under the laws of the
State of  California  and is in good  standing  in each  jurisdiction  where the
properties owned, leased or operated,  or the business conducted,  by it require
such  qualification  except for such failure to so qualify or to be in such good
standing,  which,  when taken together with all other such  failures,  would not
have a material adverse effect on the financial condition,  properties, business
or results of operations of AmHSPP. AmHSPP has the requisite power and authority
to carry on its business as it is now being conducted.

            b.  Authority.  AmHSPP has the requisite power and authority and has
taken all action necessary in order to execute and deliver this Agreement and to
consummate the  transactions  contemplated  hereby.  Except as may be limited by
applicable bankruptcy, insolvency,  reorganization,  moratorium and similar laws
affecting  creditors'  rights and remedies  generally and general  principles of
equity and the  discretion of a court in granting  equitable  remedies  (whether
validity,  binding effect or enforceability is considered in a proceeding at law
or in  equity),  this  Agreement  is a valid and  binding  agreement  of AmHSPP,
enforceable against AmHSPP in accordance with its terms.

            c. Governmental Filings; No Violations.

                 i. Except for (i) those filings  which AmHSPP  intends to make,
if  necessary  or  advisable,  in the normal  course of its affairs and (ii) any
filings and/or  approvals or clearances  required under the HSR Act, no notices,
reports or other  filings are  required to be made by AmHSPP  with,  nor are any
consents,  registrations,   approvals,  clearances,  permits  or  authorizations
required to be obtained by AmHSPP from,  any  Governmental  Entity in connection
with the execution and delivery of this Agreement by AmHSPP and the consummation
by AmHSPP of the transactions contemplated hereby, the failure to make or obtain
any or all of which could  prevent,  materially  delay or materially  burden the
transactions contemplated by this Agreement.

                 ii. The execution  and delivery of this  Agreement by AmHSPP do
not, and the consummation of the transactions contemplated hereby by AmHSPP will
not,  constitute or result in (1) a breach or violation of, or a default  under,
AmHSPP's Agreement of Limited  Partnership or, (2) assuming  compliance with the
matters referred to in the foregoing  paragraph (i), a breach or violation of, a
default under, the acceleration of or the creation of a lien,  pledge,  security
interest or other encumbrance on assets (with or without the giving of notice or
the lapse of time)  pursuant to, any  provision of any Contract of AmHSPP or any
law,  ordinance,  rule or  regulation  or  judgment,  decree,  order,  award  or
governmental or  non-governmental  permit or license to which AmHSPP is subject,
except, in the case of clause (2) above, for such breaches, violations, defaults
or

                                     11


accelerations  that,  alone or in the aggregate,  could not prevent,  materially
delay or materially burden the transactions contemplated by this Agreement.

            d.  Brokers and  Finders.  Neither  AmHSPP nor any of its  officers,
directors, affiliates or employees has employed any broker or finder or incurred
any liability for any brokerage fees, commissions or finders' fees in connection
with the transactions contemplated hereby.

            e. Investment  Intent.  The Warrants are being, and AmHSPP presently
intends that the shares of Common Stock to be received  upon any exercise of the
Warrants  (the  "Shares")  will be,  acquired  for  investment  for AmHSPP's own
account and not with a view to the resale or  distribution  of any part thereof,
and AmHSPP has no present intention of selling, granting any participation in or
otherwise  distributing the same. AmHSPP is an "accredited  investor" within the
meaning of Rule 501 under the  Securities  Act of 1933,  as  amended  (the "1933
Act"),  and was not organized for the specific purpose of acquiring the Warrants
or the Shares;  AmHSPP has  sufficient  knowledge and experience in investing in
companies similar to the Parent in terms of the Parent's state of development so
as to be able to evaluate the risks and merits of its  investment  in the Parent
and it is able  financially  to bear the risks  thereof;  without  limiting  the
representations  of the Parent and the Partner  set forth above in Section  4.1,
AmHSPP has had an opportunity to discuss the Parent's  business,  management and
financial  affairs with the  Parent's  management  and to obtain any  additional
information  necessary to verify the accuracy of the information furnished to it
concerning  the business,  management and financial  affairs of the Parent;  and
AmHSPP understands that (A) the issuance of the Warrants to AmHSPP has not been,
and the issuance of the Shares upon any  exercise of the  Warrants  will not be,
registered  under  the 1933 Act by  reason of their  issuances  in  transactions
exempt from the  registration  requirements of the 1933 Act (including,  without
limitation,  pursuant  to Section  4(2)  thereof or Rule 505 or 506  promulgated
under the 1933 Act),  (B) the Warrants and the Shares must be held  indefinitely
unless a subsequent  disposition  thereof is registered under the 1933 Act or is
exempt  from such  registration,  (C) the  Warrants  and the Shares  will bear a
legend to such effect and (D) the Parent  will make a notation  on its  transfer
books to such effect.

         a.  Information.  The Partner  shall  contribute  (i) the Defined  Care
outcomes  information  of the  Partner  and its  affiliates  and other  relevant
information  to each Database (to the extent  permitted by  applicable  laws and
regulations)  and (ii) other  specified  resources  necessary to establish  each

Database and (ii) make  available  to each  participating  Facility  options for
accessing the content of its respective Database which are within the reasonable
technical ability of the Partner.

     5.3 Participating Facilities.  Each participating Facility which desires to
establish a Database with the Partner shall contribute  thereto its Defined Care
outcomes  information  which is  generated  through its Facility  Agreement  and
affiliation  with the Partner (to the extent  permitted by  applicable  laws and
regulations).   Each  Facility  shall  retain   ownership  of  the   information
contributed by such Facility.

     5.4 Use of the Database.

         a.  Facilities.  Each  participating  Facility  may use its  respective
Database,  during  the term of the  Facility  Agreement  at issue,  for (i) best
demonstrated  practice  comparisons  and  other  comparative  purposes  and (ii)
contract  negotiation  and  marketing  with third  parties  (including,  without
limitation,   third  party  payors).  Any  other  uses  of  the  Database  by  a
participating  Facility  (and/or AmHSPP) shall require the prior written consent
of the Partner.

         b.  Partner.  The Partner  may use a  Database,  during the term of the
Facility  Agreement at issue,  for purposes  related  directly to such  Facility

modified, with respect to any Facility Agreement, by the terms of such Facility
Agreement.

                   CLINICAL ADVISORY GROUP AND RELATED MATTERS

     6.1 Clinical Advisory Group.

         a. Formation/Purpose. Within ninety (90) days after the Effective Date,
the parties agree to form a clinical  advisory group with  representatives  from
the Partner and certain of the  Facilities  interested in  participating  in the
Association (the "Advisory Group"). The purpose of the Advisory Group will be to
provide  information to the Partner,  AmHSPP and the Facilities and to assist in
the  development  of resources  available  for  utilization  with respect to the
Association   (including,   without  limitation,   an  outcomes  database,  best
demonstrated  practices,  managed care  contracting  and clinical  protocols and
pathways).

         b.  Meetings/Attendance.  The Advisory Group will plan to meet at least
four times per year,  and the  Partner and its  representatives  will attend and
participate in such meetings at their own expense.

         c. Speakers.  The Partner may provide  reasonable  financial support to
host and  compensate  speakers for  meetings of the Advisory  Group and/or other
national  meetings of  representatives  of the Facilities as may be agreed to by
the Partner from time to time.

     6.2 Subacute Care Studies.  In the event that one or more Facilities desire
to conduct or otherwise  cause the  performance of studies  relevant to subacute
care,  the  Partner  will  consider  providing  such  financial  support for the
performance and publishing of such studies as the Partner and such Facility(ies)
shall agree.


                                    ARTICLE 7

                             PURCHASING AFFILIATION

     AmHSPP   acknowledges   that  the  Partner  meets  the   requirements   for
participation  in APS'  Affiliates-Corporate  Entity ("ACE")  program and, at no
additional cost, may have access to AmHSPP's purchasing contracts. The Partner's
participation  in the ACE program  will be the  subject of a separate  agreement
between the Partner and APS (or its affiliates)  with such reasonable  terms and
provisions as shall be mutually satisfactory to the parties; provided,  however,
that the Partner  acknowledges that it will not be eligible for any dividends or
distributions  made to the direct or indirect  shareholders of AmHSPP and/or APS
(including, without limitation, dividends resulting from ACE-related revenue).

                                    ARTICLE 8

                                  MISCELLANEOUS

     8.1 No Partnership.  Nothing in this Agreement shall be construed to create
any  partnership,  joint  venture,  franchise or similar  arrangement  among the
parties. No party has the right or authority to enter into any Contract,  assume
any  obligation  or make any  warranty or  representation  on behalf of another,
except where and to the extent specifically authorized in writing to do so.

     8.2 Assignment.

         a. The  Partner  acknowledges  that the  Partner  has been  selected by
AmHSPP for  participation  in the  Association  due to unique  attributes of the
Partner.  Accordingly,  the Partner's  involvement in the  Association  (and any
rights and  obligations  with  respect  thereto) may not be assigned by contract
without the prior written consent of AmHSPP (in its sole discretion);  provided,
however,  that the Partner may (i) assign any or all of its rights and interests
with  respect  to the  Association  to one or more or its  affiliates  and  (ii)
designate one or more of its affiliates to perform its obligations  with respect
to the Association (in any or all of which cases the Partner  nonetheless  shall
remain liable and responsible for the performance of all of its obligations with
respect to the Association); and provided, further, that any assignment must not
materially  and  adversely  affect the ability of the parties to comply with the
provisions of Section 8.10 below.

         b.  Except  for any  assignment  to a  direct  or  indirect  affiliate,
AmHSPP's  involvement in the Association  (and any rights and  obligations  with
respect  thereto)  may not be  assigned by  contract  without the prior  written
consent of the Partner (in its sole discretion). Without limitation, the Partner
(i)  acknowledges  that  American  Healthcare  Systems (an affiliate of AmHSPP),
Premier Health Alliance and SunHealth Alliance, Inc. have recently been combined
into APS and (ii) agrees that the Association  (and the  participation of AmHSPP

any  successor  entities in  connection  with such  combination  (so long as the
transactions do not conflict with any material applicable law).  Notwithstanding
the  foregoing  provisions  of this  Section  8.2(b),  any  assignment  must not
materially  and  adversely  affect the ability of the parties to comply with the
provisions of Section 8.10 below.

limitation,  the Warrants) shall be governed by New York law (without  reference

     8.4  Agreement/Amendment.  This  Agreement and the  Appendices and Exhibits
hereto  contain  the entire  agreement  among the  parties  with  respect to the
subject  matter hereof and supersede all prior  arrangements  or  understandings
with respect thereto (including,  without limitation, that certain Memorandum of
Understanding  among  the  parties  dated  October  12,  1995).  The  terms  and
provisions  of  this  Agreement  may be  modified  or  amended,  temporarily  or

party to this  Agreement  may,  by written  notice to the other  parties,  waive
compliance  with any of the  provisions of this  Agreement  binding on the other
parties for its benefit.  The failure of any party hereto to enforce at any time
any of the  provisions  of this  Agreement  shall in no way be construed to be a
waiver of any such  provision,  nor in any way to affect  the  validity  of this
Agreement  or the  right of such  party  thereafter  to  enforce  each and every
provision.  No waiver of any  breach of or  non-compliance  with this  Agreement
shall  be  held  to  be  the  waiver  of  any  other  or  subsequent  breach  or
non-compliance.

      I.   The Partner intends to provide resources and its commitment to create

      II.  The  Partner  will  offer  a  comprehensive  list  of services  and

           fits its needs.

           to maximize the local "fit" and meet the cultural needs of each 
           Facility. Options discussed include everything from management 
           services and sub-contracting to formal joint ventures and 
           co-investments.

           clinical  practice  comparisons will be provided to those Facilities
           participating   in  the Association (through Facility Agreements).

                          ELEMENTS FOR JOINT VENTURE OR
                     MANAGEMENT SERVICES FACILITY AGREEMENTS


Joint Venture Terms

o        Exit Strategy: an ability for either party to exit the venture, in such
         party's discretion, and thereby dissolve the venture.

o        Non-Compete:  a non-compete covenant by the Partner for the term of the
         venture and a reasonable  period of time  following the  dissolution of
         any equity relationship (with due respect, as applicable,  to antitrust
         and related laws).

o        Structural  Flexibility:  structuring of the venture to avoid conflicts
         with  a  Facility's   tax-exempt   status,   general  fraud  and  abuse
         considerations and  other potentially applicable
         restrictions/considerations.

o        Governance:   creation   of  (i)  a   governing   body   comprised   of
         representatives of both parties and (ii) a clinical advisory board also
         comprised  of  representatives  of  both  parties  (to  report  to  the
         governing body).

o        Net Income  Calculation:  a  mutually-acceptable  method of calculating
         venture  profit  for  purposes  of  determining  distributions  to  the
         parties.

o        Management  Services:  the Partner will agree to consider the provision
         of management services [CONFIDENTIAL  TREATMENT REQUESTED] in any joint
         venture  relationship  pending  the  negotiation  of  preferred  terms;
         however, if a series of joint venture Facility  Agreements  indicates a
         tendency  toward  a  certain  fee  structure  or a  selected  group  of
         alternative  fee  structures,  such  structure(s)  shall  be  used as a
         benchmark  for  the  negotiation  of  future  joint  venture   Facility
         Agreements.

Management Services

o        Fees: to be  established  at  competitive  market rates;  however,  the
         Partner  agrees  to  limit  its  subacute  care   management   fees  to
         [CONFIDENTIAL  TREATMENT  REQUESTED]  percent of any Facility's Defined
         Care revenue which is the subject of an agreement with the Partner.

o        Term:  the Partner is willing to negotiate a  three-year  term with the
         option to renew for two additional terms of three years each.




o        Termination:  either party may terminate with the written  agreement of
         the other or upon  provision of 90 days' written notice to the other in
         such party's discretion.

o        Non-Compete:   a  non-compete   covenant  by  the  Partner  with  terms
         satisfactory  to both parties  (with due  respect,  as  applicable,  to
         antitrust and related laws).

                               WARRANT TO PURCHASE
                                 210,000 SHARES
                 OF THE COMMON STOCK, PAR VALUE $.01 PER SHARE,
                          OF MARINER HEALTH GROUP, INC.





         For value  received,  AmHS  PURCHASING  PARTNERS,  L.P.,  a  California
limited partnership,  or its permitted successors or assigns (collectively,  the
"Investor"),  are entitled to subscribe  for and  purchase  from MARINER  HEALTH
GROUP,  INC., a Delaware  corporation (the  "Company"),  from and after the date
hereof, up to 210,000 fully paid and nonassessable  shares (the "Shares") of the
Company's  common  stock,  par value  $.01 per share  ("Common  Stock"),  at the
purchase  price of $11.375  per Share  (the  "Exercise  Price").  The number and
character of Shares issuable  pursuant to this Warrant are subject to adjustment
as provided  herein.  The Investor's  right to purchase  Shares pursuant to this
Warrant shall terminate on January 5, 2001.


         This Warrant is subject to the following additional  provisions,  terms
and conditions:


   1.    Exercise of Warrant.


         a. Manner of  Exercise.  This  Warrant may be  exercised  by the holder
hereof, in whole or in part, by surrender of this Warrant, together with written
notice of exercise (a sample form of exercise is attached  hereto as Exhibit A),
to the Company at the principal  office of the Company  (which,  for purposes of
this Warrant, shall be deemed to be the Company's address for notice purposes as
provided in Section 8 below) accompanied by payment (in cash, certified check or
bank draft payable to the order of the Company) of the Exercise Price multiplied
by the  number of Shares  for  which  this  Warrant  is being  exercised,  or by
exercise of the Net Exercise Right as provided in Section 1(b) below.

         b.  Net  Exercise  Right.  In lieu of  payment  of the  Exercise  Price
pursuant to Section 1(a) above, this Warrant may 

                                      1

also be exercised,  in whole or in part,  by surrender of this Warrant  together
with written notice of exercise specifying the holder's election to convert all,
or any specified  portion,  of this Warrant (the "Net Exercise  Right") into the
number of Shares equal to the quotient obtained by dividing:

         (x) the  value of the  Shares  for  which  the  Warrant  is then  being
         exercised  (determined by subtracting  the aggregate  Exercise Price of
         such  Shares in effect  immediately  prior to the  exercise  of the Net
         Exercise  Right  from the  aggregate  fair  market  value of the Shares
         immediately prior to the exercise of the Net Exercise Right) by

         (y) the  fair  market  value  of one  Share  immediately  prior  to the
         exercise of the Net Exercise Right.

The fair market value of a Share as of a particular  date shall be determined as
follows:

                   (1) If the Common  Stock is publicly  traded on a  particular
valuation date, fair market value on such date shall be:

         (i) the  closing  sale  price of the  Common  Stock,  as  quoted on any
         national  securities  exchange  on which such stock shall be listed and
         registered,  on the business day  immediately  preceding  the valuation
         date;

         (ii) the closing sale price of the Common Stock,  if such stock is then
         quoted  on  the  National  Association  of  Securities  Dealers,   Inc.
         ("NASDAQ")  National Market, on the business day immediately  preceding
         the valuation date; or

         (iii) if the Common  Stock is not then traded on a national  securities
         exchange or on the NASDAQ National Market, but is quoted on NASDAQ, the
         average of the  closing  bid and asked  prices for the Common  Stock as
         reported  on NASDAQ  on the  business  day  immediately  preceding  the
         valuation date.

                   (2)  If  the  Common  Stock  is  not  publicly  traded  on  a
particular valuation date, fair market value on such date shall be determined by
the Board of Directors of the Company acting in good faith (taking into account,
as such Board of Directors  acting in good faith deems  appropriate,  any recent
corporate events involving a determination of value for the Company's securities
(e.g.,  the closing of an offering of  securities  or the  granting of incentive
stock options)).

         c. When  Exercise  Effective.  Each  exercise of this Warrant  shall be
deemed to have been effected on the date on which the Company  issues the Shares
for which the Warrant has been exercised;  provided,  however,  that the Company
shall issue (or cause to be issued)  the Shares for which this  Warrant has been
exercised  within  three (3)  business  days after an  exercise

                                      2

pursuant to the  provisions of Section 1(a) above (and, if  applicable,  the Net
Exercise Right provisions of Section 1(b) above).

         d. Delivery of Stock Certificates. Certificates representing the Shares
purchased  upon any exercise of this Warrant shall bear the  restrictive  legend
set forth in Section 9 below and shall be  delivered  to the  Investor  promptly
following such exercise.  A new Warrant exercisable for the number of Shares, if
any, with respect to which this Warrant shall not have been exercised shall also
be  delivered to the  Investor.  No  fractional  Shares shall be issued upon the
exercise of this Warrant; rather, the Investor shall receive an amount, in cash,
equal to the fair market value of any such fractional  Shares  (determined  with
reference to the provisions of Section 1(b) above).

         e. Automatic  Exercise.  In the event that the fair market value of the
Shares (determined with reference to the provisions of Section 1(b) above) shall
at any time exceed the Exercise  Price,  on a per-Share  basis,  by  one-hundred
dollars ($100.00), then this Warrant, with respect to all Shares then available,
shall,  without action on the part of any party hereto, be deemed  automatically
exercised (pursuant to the net exercise provisions of Section 1(b) above, unless
the Investor  promptly  provides the  appropriate  Exercise  Price amount to the
Company). The Investor will provide the Company with prompt notice regarding any
automatic exercise pursuant to the provisions of this Section 1(e).

     2.    Shares Issuable Upon Exercise.

         a. Reserved.  The Company covenants and agrees that all Shares that may
be issued upon the exercise of this Warrant shall,  upon issuance pursuant to an
exercise of this Warrant in accordance  with its terms,  be duly  authorized and
validly  issued,  fully  paid and  nonassessable  Shares,  free and clear of all
preemptive  rights.  The Company will at all times  reserve and keep  available,
solely for issuance and delivery upon the exercise of this Warrant,  such number
of Shares of the Common  Stock as shall be  issuable  from time to time upon the
exercise of this Warrant.

         b.  Listed.  Prior to the  issuance  of any Shares,  the Company  shall
secure the listing or  quotation  of such Shares upon each  national  securities
exchange or  automated  quotation  system,  if any,  upon which shares of Common
Stock are then listed or traded  (subject to  official  notice of issuance  upon
exercise of this  Warrant)  and shall  maintain,  so long as any other shares of
Common  Stock shall be so listed or traded,  such  listing or  quotation  of all
Shares from time to time issuable upon the exercise of this Warrant. The Company
shall so list or  secure  quotation  on each  national  securities  exchange  or
automated quotation system, and shall maintain such listing or

 
                                        3

quotation of, any other shares issuable upon any exercise of this Warrant if and
so long as any  shares  of the same  class  shall be  listed  or  quoted on such
national securities exchange or automated quotation system.

     3. Adjustment.  The Exercise Price and/or the number and type of securities
issuable upon any exercise of this Warrant  shall be subject to adjustment  from
time to time as hereinafter provided in this Section 3.

         a. If the Company,  at any time,  divides the outstanding shares of its
Common Stock into a greater number of shares (whether pursuant to a stock split,
stock dividend or otherwise),  and conversely,  if the outstanding shares of its
Common Stock are combined into a smaller number of shares, the Exercise Price in
effect   immediately   prior  to  such   division   or   combination   shall  be
proportionately  adjusted to reflect the  reduction  or increase in  outstanding
shares.

         b. If any capital  reorganization  or  reclassification  of the capital
stock of the  Company,  or  consolidation  or merger of the Company with another
corporation,  or the sale of all or  substantially  all of its assets to another
corporation  shall be  effected  in such a way that  holders of shares of Common
Stock  shall be  entitled  to receive  stock,  other  securities  or assets with
respect to or in exchange for such shares of Common Stock,  then, as a condition
of such  reorganization,  reclassification,  consolidation,  merger or sale, the
holder of this  Warrant  shall have the right to purchase  and receive  upon the
basis and upon the terms and conditions specified in this Warrant and in lieu of
the Shares immediately  theretofore purchasable and receivable upon the exercise
of this Warrant,  such shares of stock, other securities or assets as would have
been issued or delivered to the  Investor if the  Investor  had  exercised  this
Warrant   and  had   received   such  Shares   prior  to  such   reorganization,
reclassification,  consolidation,  merger or sale.  The Company shall not effect
any such consolidation or merger unless, prior to the consummation  thereof, the
successor   corporation  (if  other  than  the  Company)   resulting  from  such
consolidation or merger shall assume by written  instrument  executed and mailed
to the Investor  (i) the  obligation  to deliver to the Investor  such shares of
stock,  other  securities  or  assets  as,  in  accordance  with  the  foregoing
provisions,  the  Investor  may be  entitled  to  purchase  and (ii)  the  other
obligations of the Company set forth or referred to in this Warrant.

         c. If, after the initial issuance of this Warrant to the Investor,  the
Company  shall  declare a  dividend  or  distribution  payable to holders of the
Common  Stock  (whether  payable  in cash,  securities  or other  assets  of the
Company),  upon any exercise of this  Warrant the Investor  shall be entitled to
receive,  and  the  Company  shall  promptly  pay  to  the  Investor,  any  such
dividend(s)  and/or  distribution(s)  (as well as any other cash,  securities or
other assets which the Investor  would 

                                       4


have received had it held any securities received in any such dividend(s) and/or
distribution(s)), also giving effect to the other provisions of this Section 3.

         d. Upon each  adjustment  of the Exercise  Price,  the  Investor  shall
thereafter be entitled to purchase,  at the Exercise  Price  resulting from such
adjustment,  the number of Shares  obtained by multiplying the Exercise Price in
effect  immediately prior to such adjustment by the number of Shares purchasable
pursuant  hereto  immediately  prior to such adjustment and dividing the product
thereof by the Exercise Price resulting from such adjustment.

         e. Promptly following any adjustment of the Exercise Price, the Company
shall give written notice thereof (by first class mail,  postage prepaid) to the
Investor (at the Investor's address as shown on the books of the Company), which
notice shall state the Exercise  Price  resulting  from such  adjustment and the
increase or decrease,  if any, in the number of Shares purchasable at such price
upon the exercise of this Warrant, setting forth in reasonable detail the method
of calculation and the facts upon which such calculation is based.

         f. The terms of this Warrant  shall be binding upon the  successors  of
the Company.

     4. No Rights as  Stockholder;  Notice.The  Investor  shall not by virtue of
this Warrant be entitled to any rights of a stockholder of the Company. However,
the  Company  shall  give  notice to the  Investor  if at any time  prior to the
expiration or exercise in full of this Warrant any of the following events shall
occur:

     (a) the Company shall declare any dividend or distribution  with respect to
         its capital stock;

     (b) a  dissolution,  liquidation  or  winding  up of the  Company  shall be
         proposed; or

     (c) a capital  reorganization or  reclassification  of the capital stock of
         the Company,  any  consolidation  or merger of the Company with or into
         another corporation, any transaction or series of transactions in which
         more than fifty percent  (50%) of the voting  securities of the Company
         are  transferred  to another  person,  or of any sale or  conveyance to
         another  corporation  of the  property of the Company as an entirety or
         substantially as an entirety.

Such giving of notice  shall be effected at least  fifteen  (15)  business  days
prior  to the  date  fixed as a  record  date or  effective  date or the date of
closing of the  Company's  stock  transfer  books for the  determination  of the
stockholders entitled to such dividend or distribution, or for the 

                                       5

determination  of the  stockholders  entitled to vote on such  proposed  merger,
consolidation,  sale, conveyance,  dissolution,  liquidation or winding up. Such
notice shall specify such record date or the date of closing the stock  transfer
books, as the case may be.

     5.  Transfers.  This Warrant may not be  transferred,  in whole or in part,
without the prior written consent of the Company;  provided,  however, that such
consent  shall not be  unreasonably  withheld in the event of any transfer to an
affiliate of the Investor.  Until any such  transfer,  the Company may treat the
registered  owner  hereof  as the owner for all  purposes  (notwithstanding  any
markings or notations on the face of this Warrant).

     6. Loss, Theft,  Destruction or Mutilation.  Upon receipt by the Company of
satisfactory  evidence of the loss,  theft,  destruction  or  mutilation of this
Warrant and either (in the case of loss,  theft or destruction)  indemnification
satisfactory to the Company or (in the case of mutilation) the surrender of this
Warrant for cancellation,  the Company will execute and deliver to the Investor,
without charge, a Warrant of like denomination.

     7. Public  Reporting.  With a view to making  available to the Investor the
benefits of Rule 144 ("Rule 144")  promulgated under the Securities Act of 1933,
as amended (the "1933 Act"),  and any other rule or regulation of the Securities
and Exchange  Commission (the "SEC") that may at any time permit the Investor to
sell Shares to the public without registration,  the Company agrees that, for so
long  as a  class  of its  securities  is  registered  under  Section  12 of the
Securities  Exchange Act of 1934, as amended (the "1934 Act"), the Company will:
(i) make and keep public  information  available,  as those terms are understood
and defined in Rule 144, at all times; (ii) file with the SEC in a timely manner
all reports and other  documents  required of the Company under the 1933 Act and
the 1934 Act; and (iii) furnish to the Investor,  forthwith upon request,  (a) a
written  statement  by the  Company  that it has  complied  with  the  reporting
requirements  of Rule 144, the 1933 Act and the 1934 Act, (b) a copy of the most
recent  annual or  quarterly  report of the Company  filed with the SEC and such
other  reports and  documents  so filed by the Company  which the  Investor  may
reasonably  request,  and  (c)  such  other  information  as may  be  reasonably
requested in availing the  Investor of any rule or  regulation  of the SEC which
permits the selling of any Shares without registration under the 1933 Act.

     8. Notices.  Any notice or demand desired or required to be given hereunder
shall be in writing and given (except as

                               WARRANT TO PURCHASE
                             UP TO 1,890,000 SHARES
                 OF THE COMMON STOCK, PAR VALUE $.01 PER SHARE,
                          OF MARINER HEALTH GROUP, INC.





         For value  received,  AmHS  PURCHASING  PARTNERS,  L.P.,  a  California
limited partnership,  or its permitted successors or assigns (collectively,  the
"Investor"),  are entitled to subscribe  for and  purchase  from MARINER  HEALTH
GROUP,  INC., a Delaware  corporation (the  "Company"),  from and after the date
hereof,  up to 1,890,000 fully paid and  nonassessable  shares (the "Shares") of
the  Company's  common stock,  par value $.01 per share  ("Common  Stock").  The
number and character of Shares issuable  pursuant to this Warrant are subject to
adjustment as provided herein.


         This Warrant is subject to the following additional  provisions,  terms
and conditions:


        1.  Vesting of Shares; Termination.

                    a. Measurement  Dates. On December 31 of each year following
the date hereof  (excluding  December  31, 1995) and ending on December 31, 2000
(each such date being herein referred to as a "Measurement  Date"),  a number of
the Shares (a "Tranche of Shares") shall "vest" (i.e.,  the Investor's  right to
purchase such shares shall become  exercisable)  as  determined  pursuant to the
provisions of Schedule 1 attached hereto.

                    b.  Vesting  Tranches.  Each  Tranche  of  Shares  shall  be
purchasable at the price per Share (the "Exercise Price") determined pursuant to
Section 2 below. Promptly following each Measurement Date (or as soon thereafter
as information  regarding  vesting  criteria becomes  available),  the number of
Shares  which shall  comprise  the Tranche of Shares for such  Measurement  Date
shall be determined (as provided herein),  and a statement of such determination
as well as a statement of the Exercise Price for such Tranche of Shares shall be
provided  by the Company to the  Investor.  Copies of such  statements  for each
Measurement

                                      1


Date shall be kept with the Company's  records (and, if the Investor  chooses to
do so, attached to this Warrant).

                    c.  Termination of Purchase Right. The right of the Investor
to purchase Shares shall terminate, with respect to each Tranche of Shares, five
years after the relevant Measurement Date for such Tranche of Shares.

           2. Exercise Price. The Exercise Price, on a per-share of Common Stock
basis, for each Tranche of Shares shall be the "fair market value" of a Share as
of the relevant  Measurement  Date for such Tranche of Shares.  The "fair market
value" of a Share,  as of a  particular  Measurement  Date (or  other  specified
date), shall be determined as follows:

                    a. Publicly  Traded.  If the Common Stock is publicly traded
on a particular  Measurement  Date (or other  specified  date),  the fair market
value of a Share on such Measurement Date (or other specified date) shall be:

           (i) the average of the closing sale prices for the Common  Stock,  as
         quoted on any national securities exchange on which such stock shall be
         listed and  registered,  for the ten  trading  days ending on the third
         trading day prior to the Measurement Date (or other specified date);

           (ii) the average of the closing sale prices for the Common Stock,  if
         such stock is then quoted on the  National  Association  of  Securities
         Dealers,  Inc.  ("NASDAQ")  National  Market,  for the ten trading days
         ending on the third trading day prior to the Measurement Date (or other
         specified date); or

           (iii) if the Common Stock is not then traded on a national securities
         exchange or on the NASDAQ National Market, but is quoted on NASDAQ, the
         average of the closing bid and asked  prices for the Common  Stock,  as
         reported  on  NASDAQ,  for the ten  trading  days  ending  on the third
         trading day prior to the Measurement Date (or other specified date);

provided,  however, that if the Company shall declare a dividend or distribution
(as  discussed in Section 5(c) below)  payable to holders of the Common Stock of
record on any date during the period  (inclusive)  beginning with the first date
of any period of trading days utilized to determine an Exercise  Price (or other
calculation  of fair market value) and ending on the date  immediately  prior to
the  Measurement  Date (or other specified  date),  then such Exercise Price (or
other  calculation  of fair market value) shall be  appropriately  discounted to
remove  the  effect  of the  value of such  dividend  or  distribution  from the
calculation  of the Exercise  Price (or other  calculation of fair market value)
for dates prior to and including the record date.


                                       2


                    b. Not Publicly Traded.  If the Common Stock is not publicly
traded on a particular  Measurement  Date (or other  specified  date),  the fair
market value of a Share as of such  Measurement  Date (or other  specified date)
shall be  determined  by the Board of  Directors  of the Company  acting in good
faith  (taking into  account,  as such Board of  Directors  acting in good faith
deems  appropriate,  any recent  corporate  events  involving a determination of
value  for the  Company's  securities  (e.g.,  the  closing  of an  offering  of
securities or the granting of incentive stock options)).

           3. Exercise of Warrant.

                    a. Manner of Exercise. To the extent then exercisable,  this
Warrant may be exercised by the holder hereof, in whole or in part, by surrender
of this Warrant,  together with written  notice of exercise in the form attached
hereto as Exhibit A ("Exercise Notice"),  to the Company at the principal office
of the Company (which,  for purposes of this Warrant,  shall be deemed to be the
Company's  address  for  notice  purposes  as  provided  in  Section  10  below)
accompanied  by payment (in cash,  certified  check or bank draft payable to the
order of the Company) of the aggregate  Exercise  Price for the number of Shares
for which this Warrant is being exercised (as set forth in the Exercise Notice),
or by exercise of the Net Exercise Right as provided in Section 3(b) below.

                    b. Net Exercise  Right. To the extent then  exercisable,  in
lieu of payment  of the  Exercise  Price  pursuant  to  Section  3(a) above this
Warrant may also be exercised, in whole or in part, by surrender of this Warrant
together with a written notice of exercise  specifying the holder's  election to
convert all, or any  specified  portion,  of the vested  portion of this Warrant
(the "Net  Exercise  Right")  into the  number of Shares  equal to the  quotient
obtained by dividing:

         (x) the  value of the  Shares  for  which  the  Warrant  is then  being
         exercised  (determined by subtracting  the aggregate  Exercise Price of
         such  Shares in effect  immediately  prior to the  exercise  of the Net
         Exercise  Right  from the  aggregate  fair  market  value of the Shares
         immediately prior to the exercise of the Net Exercise Right) by

         (y) the  fair  market  value  of one  Share  immediately  prior  to the
         exercise of the Net Exercise Right.

The fair market  value of a Share as of a  particular  date shall be  determined
pursuant to Section 2 above.

                    c. When  Exercise  Effective.  Each exercise of this Warrant
shall be deemed to have been  effected on the date on which the  Company  issues
the Shares for which the Warrant has been exercised; provided, however, that the
Company  shall issue (or cause to be issued)  the Shares for which this  Warrant
has

                                       3


been exercised within three (3) business days after an exercise  pursuant to the
provisions of Section 3(a) above (and,  if  applicable,  the Net Exercise  Right
provisions of Section 3(b) above).

                    d. Delivery of Stock Certificates. Certificates representing
the  Shares  purchased  upon  any  exercise  of  this  Warrant  shall  bear  the
restrictive  legend set forth in Section 11 below and shall be  delivered to the
Investor  promptly  following such exercise.  A new Warrant  exercisable for the
number of Shares, if any, with respect to which this Warrant shall not have been
exercised shall also be delivered to the Investor. No fractional Shares shall be
issued upon the exercise of this Warrant;  rather, the Investor shall receive an
amount,  in cash,  equal to the fair market value of any such fractional  Shares
(determined with reference to the provisions of Section 2 above).

                    e.  Automatic  Exercise.  In the event that the fair  market
value of any Tranche of Shares  (determined  with reference to the provisions of
Section 2 above) shall at any time exceed the Exercise Price for such Tranche of
Shares,  on a per-Share  basis,  by  one-hundred  dollars  ($100.00),  then this
Warrant,  with respect to all Shares  within any such Tranche of Shares,  shall,
without  action  on the  part  of any  party  hereto,  be  deemed  automatically
exercised  (pursuant to the Net Exercise Right provisions of Section 3(b) above,
unless the Investor promptly  provides the appropriate  Exercise Price amount to
the  Company).  Such an  automatic  exercise  shall not affect (i) the  unvested
portion  of this  Warrant  nor (ii) this  Warrant  insofar  as it relates to any
Tranche of Shares which does not trigger the condition of the first  sentence of
this  Section  3(e).  The Investor  will provide the Company with prompt  notice
regarding  any  automatic  exercise  pursuant to the  provisions of this Section
3(e).

           4. Shares Issuable Upon Exercise.

                    a.  Reserved.  The  Company  covenants  and agrees  that all
Shares that may be issued upon the exercise of this Warrant shall, upon issuance
pursuant to an exercise of this Warrant in  accordance  with its terms,  be duly
authorized and validly issued,  fully paid and  nonassessable  Shares,  free and
clear of all preemptive  rights.  The Company will at all times reserve and keep
available,  solely for issuance and delivery  upon the exercise of this Warrant,
such number of Shares of the Common Stock as shall be issuable from time to time
upon the exercise of this Warrant.

                    b. Listed.  Prior to the issuance of any Shares, the Company
shall  secure  the  listing  or  quotation  of such  Shares  upon each  national
securities  exchange or automated quotation system, if any, upon which shares of
Common Stock are then listed or traded  (subject to official  notice of issuance
upon

                                       4


exercise of this  Warrant)  and shall  maintain,  so long as any other shares of
Common  Stock shall be so listed or traded,  such  listing or  quotation  of all
Shares from time to time issuable upon the exercise of this Warrant. The Company
shall so list or  secure  quotation  on each  national  securities  exchange  or
automated quotation system, and shall maintain such listing or quotation of, any
other  shares  issuable  upon any exercise of this Warrant if and so long as any
shares of the same class shall be listed or quoted on such  national  securities
exchange or automated quotation system.

           5.  Adjustment.  The Exercise  Price(s) and/or the number and type of
securities  issuable  upon any  exercise  of this  Warrant  shall be  subject to
adjustment from time to time as hereinafter provided in this Section 5.

                    a. If the  Company,  at any time,  divides  the  outstanding
shares of its Common Stock into a greater number of shares (whether  pursuant to
a stock split, stock dividend or otherwise),  and conversely, if the outstanding
shares of its Common Stock are  combined  into a smaller  number of shares,  the
Exercise  Price(s) in effect  immediately  prior to such division or combination
shall be  proportionately  adjusted  to reflect  the  reduction  or  increase in
outstanding shares.

                    b. If any capital  reorganization or reclassification of the
capital  stock of the Company,  or  consolidation  or merger of the Company with
another  corporation,  or the sale of all or substantially  all of its assets to
another  corporation  shall be effected in such a way that  holders of shares of
Common Stock shall be entitled to receive stock, other securities or assets with
respect to or in exchange for such shares of Common Stock,  then, as a condition
of such  reorganization,  reclassification,  consolidation,  merger or sale, the
holder of this  Warrant  shall have the right to purchase  and receive  upon the
basis and upon the terms and conditions specified in this Warrant and in lieu of
the Shares immediately  theretofore purchasable and receivable upon the exercise
of this Warrant,  such shares of stock, other securities or assets as would have
been issued or delivered to the  Investor if the  Investor  had  exercised  this
Warrant   and  had   received   such  Shares   prior  to  such   reorganization,
reclassification,  consolidation,  merger or sale.  The Company shall not effect
any such consolidation or merger unless, prior to the consummation  thereof, the
successor   corporation  (if  other  than  the  Company)   resulting  from  such
consolidation or merger shall assume by written  instrument  executed and mailed
to the Investor  (i) the  obligation  to deliver to the Investor  such shares of
stock,  other  securities  or  assets  as,  in  accordance  with  the  foregoing
provisions,  the  Investor  may be  entitled  to  purchase  and (ii)  the  other
obligations of the Company set forth or referred to in this Warrant.

                    c. If the Company shall  declare a dividend or  distribution
payable  to  holders  of the  Common  Stock of  record on


                                       5


a date on or after the  Measurement  Date for a vested  Tranche  of  Shares  (as
provided in Section 1(a) above)  (whether  payable in cash,  securities or other
assets of the  Company),  then upon any exercise of this Warrant with respect to
such vested Tranche of Shares the Investor shall be entitled to receive, and the
Company  shall  promptly  pay to  the  Investor,  any  such  dividend(s)  and/or
distribution(s) (as well as any other cash, securities or other assets which the
Investor  would have  received had it held any  securities  received in any such
dividend(s) and/or distribution(s)),  also giving effect to the other provisions
of this Section 5.

                    d.  Upon  each  adjustment  of the  Exercise  Price  for any
Tranche of Shares, the Investor shall thereafter be entitled to purchase, at the
Exercise Price  resulting from such  adjustment and with respect to such Tranche
of Shares, the number of Shares obtained by multiplying the applicable  Exercise
Price in effect immediately prior to such adjustment by the applicable number of
Shares  purchasable  pursuant  hereto  immediately  prior to such adjustment and
dividing  the  product  thereof  by  the  Exercise  Price  resulting  from  such
adjustment.  Upon any  adjustment  contemplated  by the first  sentence  of this
Section 5(d),  the number of Shares as to which an Exercise  Price has not as of
then been determined (i.e., those Shares which have not become part of a Tranche
of Shares) shall be the subject of an  appropriate  adjustment to protect fairly
the purchase rights of the Investor.

                    e. Promptly  following any adjustment of an Exercise  Price,
the Company  shall give  written  notice  thereof (by first class mail,  postage
prepaid) to the Investor (at the Investor's address as shown on the books of the
Company),  which  notice  shall state the  Exercise  Price  resulting  from such
adjustment  and the  increase  or  decrease,  if any,  in the  number  of Shares
purchasable  at such price upon the exercise of this  Warrant,  setting forth in
reasonable  detail  the  method of  calculation  and the facts  upon  which such
calculation is based.

                    f. The  terms of this  Warrant  shall  be  binding  upon the
successors of the Company.

           6. No Rights as Stockholder; Notice. The Investor shall not by virtue
of this  Warrant be  entitled  to any rights of a  stockholder  of the  Company.
However,  the Company  shall give notice to the Investor if at any time prior to
the  expiration or exercise in full of this Warrant any of the following  events
shall occur:

                  (a)   the Company shall  declare any dividend or  distribution
                        with respect to its capital stock;

                  (b)   a dissolution,  liquidation or winding up of the Company
                        shall be proposed; or


                                       6


                  (c)   a  capital  reorganization  or  reclassification  of the
                        capital  stock  of the  Company,  any  consolidation  or
                        merger of the Company with or into another  corporation,
                        any  transaction or series of transactions in which more
                        than fifty percent (50%) of the voting securities of the
                        Company are  transferred  to another  person,  or of any
                        sale  or  conveyance  to  another   corporation  of  the
                        property of the Company as an entirety or  substantially
                        as an entirety.

Such giving of notice  shall be effected at least  fifteen  (15)  business  days
prior  to the  date  fixed as a  record  date or  effective  date or the date of
closing of the  Company's  stock  transfer  books for the  determination  of the
stockholders entitled to such dividend or distribution, or for the determination
of the  stockholders  entitled to vote on such proposed  merger,  consolidation,
sale,  conveyance,  dissolution,  liquidation  or winding up. Such notice  shall
specify such record date or the date of closing the stock transfer books, as the
case may be.

           7.  Transfers.  This Warrant may not be  transferred,  in whole or in
part, without the prior written consent of the Company; provided,  however, that
such consent shall not be unreasonably  withheld in the event of any transfer to
an affiliate  of the Investor  (except that the Company may withhold its consent
in its sole discretion with respect to a transfer of any portion of this Warrant
which relates to unvested Shares (with reference to Section 1(a) above)).  Until
any such  transfer,  the Company may treat the  registered  owner  hereof as the
owner for all purposes (notwithstanding any markings or notations on the face of
this Warrant).

           8.  Loss,  Theft,  Destruction  or  Mutilation.  Upon  receipt by the
Company of satisfactory  evidence of the loss, theft,  destruction or mutilation
of  this  Warrant  and  either  (in the  case of  loss,  theft  or  destruction)
indemnification  satisfactory  to the Company or (in the case of mutilation) the
surrender of this Warrant for cancellation, the Company will execute and deliver
to the Investor, without charge, a Warrant of like denomination.

           9. Public Reporting.  With a view to making available to the Investor
the benefits of Rule 144 ("Rule 144")  promulgated  under the  Securities Act of
1933,  as amended  (the "1933  Act"),  and any other rule or  regulation  of the
Securities and Exchange  Commission  (the "SEC") that may at any time permit the
Investor to sell Shares to the public without  registration,  the Company agrees
that, for so long as a class of its securities is registered under Section 12 of
the  Securities  Exchange Act of 1934, as amended (the "1934 Act"),  the Company
will:  (i)  make and keep  public  information  available,  as those  terms  are
understood  and defined in Rule 144,  at all times;  (ii) file with the SEC in a
timely manner all reports and other documents


                                       7


required of the Company  under the 1933 Act and the 1934 Act; and (iii)  furnish
to the Investor,  forthwith upon request, (a) a written statement by the Company
that it has complied with the reporting  requirements  of Rule 144, the 1933 Act
and the 1934 Act, (b) a copy of the most recent  annual or  quarterly  report of
the Company  filed with the SEC and such other reports and documents so filed by
the  Company  which the  Investor  may  reasonably  request,  and (c) such other
information as may be reasonably  requested in availing the Investor of any rule
or  regulation  of the SEC which  permits  the  selling  of any  Shares  without
registration under the 1933 Act.

           10.  Notices.  Any notice or demand  desired or  required to be given
hereunder shall be in writing and given (except as otherwise provided herein) by

         registered or qualified  under the Federal  Securities Act of 1933 (the

                                       8


         absence  of  effective   registration  under  the  1933  Act  or  other
         compliance  under or exemption from the 1933 Act and  applicable  state
         securities laws."

           12.  Taxes.  The Company  agrees that it will pay,  and will hold the
Investor  harmless  from any and all  liability  with  respect  to, any stamp or
similar  taxes which may be determined to be payable to the State of Delaware in
connection  with the issuance,  delivery or exercise of this Warrant (as well as
the issuance or delivery of Shares upon any exercise of this Warrant).

           13.  Miscellaneous.  Neither  this Warrant nor any term hereof may be
changed,  waived,  discharged or terminated orally, but only by an instrument in
writing  signed by the party against which  enforcement  of the change,  waiver,
discharge or termination is sought. This Warrant shall be construed and enforced
in accordance with, and governed by, the laws of the State of Delaware  (without
regard to conflict of law provisions).  The Section headings in this Warrant are
for  purposes  of  reference  only and shall not limit or  otherwise  affect the
meaning hereof.


         IN WITNESS  WHEREOF,  the Company has caused this  Warrant to be signed
and delivered by a duly authorized officer as of the fifth (5th) day of January,
1996.

                                   SCHEDULE 1

                                     VESTING



         As referenced,  certain terms with initial letters  capitalized in this
Schedule 1 shall have their  respective  meanings  as set forth in that  certain
Defined Care Partner  Agreement  dated January 5, 1996 among the  Investor,  the
Company and Mariner Health Care, Inc. (the "Agreement").  Otherwise,  terms with
initial  letters  capitalized  in this  Schedule 1 shall  have their  respective
meanings as set forth in the Warrant to which this  Schedule 1 is attached  (the
"Warrant").

         Insofar  as  any  obligation  is  set  forth  in  this  Schedule  1 for
performance  by the  Partner (as defined in the  Agreement),  the Company  shall
cause the Partner to perform such  obligation or substitute its own  performance
in lieu thereof consistent with the provisions of this Schedule 1.

         Shares shall vest under the Warrant,  as of any particular  Measurement
Date, pursuant to the following formula:


           SVmd    =     (PTNII/Ratiomd) - SPV

where:
                           
           SVmd    =     The number of Shares vesting as of any Measurement Date
                         (which  number shall be rounded up to the nearest whole
                         number),  representing  the  Tranche of Shares for such
                         Measurement Date;

           PTNII   =     The number of dollars comprising Pre-Tax Net Income (as
                         defined below) for the applicable  Interval (as defined
                         below);

           Ratiomd =     The applicable Pre-Tax Net Income-to-Shares  conversion
                         ratio for the applicable  Measurement  Date (determined
                         pursuant to the Measurement  Date/Conversion Ratio grid
                         set forth below); and

           SPV     =     The number of Shares previously vested, as of any given
                         time,  under the Warrant  pursuant to the provisions of
                         this Schedule 1.
   

                                   1-1


Regardless of the results of the foregoing formula:

         (1) no more than 1,890,000 Shares,  in the aggregate,  shall vest or be
         issued upon any  exercise(s)  of the Warrant  (subject to adjustment as
         provided in Section 5 of the Warrant);

         (2) once a Tranche of Shares has vested under the Warrant, such Tranche
         of Shares (and all Shares  included  therein)  cannot  become  divested
         (e.g.,  if the  formula  produces  a  negative  number  for  any  given
         Measurement  Date, a vested Tranche of Shares (and all Shares  included
         therein) shall not be lost under the Warrant as a result); and

         (3) if the Agreement is terminated for any reason, then no Shares shall
         vest under the Warrant for any period (or as of any date) following the
         Measurement  Date which  immediately  precedes the Agreement's  date of
         termination;

provided, however, that:

         (x) if the Agreement's date of termination is a Measurement  Date, such
         Measurement  Date  shall be deemed  to be the  Measurement  Date  which
         immediately  precedes the Agreement's  date of termination for purposes
         of the Warrant  and this  Schedule 1 (e.g.,  a Tranche of Shares  shall
         vest,  as  provided  in the  Warrant  and this  Schedule  1, as of such
         Measurement Date despite the Agreement's termination);

         (y) to the extent a Tranche of Shares for a Measurement  Date preceding
         such  date  of  termination  has not as of then  been  determined,  the
         Agreement's  termination  shall not affect the determination or vesting
         of such Tranche of Shares (including,  without limitation, a Tranche of
         Shares which is the subject of the foregoing clause (x)); and

         (z) the Agreement's  termination shall not affect the provisions of the
         Warrant  with  respect  to vested  Tranches  of Shares  (and all Shares
         included therein).


Pre-Tax Net Income

         Pre-Tax Net Income,  for purposes of the  foregoing  formula,  shall be
equal to:

                  (i) the total revenue derived  (consistent with the accounting
                      principles   consistently  applied  by  the  Partner  with
                      respect to its  component of the  financial  statements of
                      the  Company  filed with the SEC) by the  Partner  (or its
                      affiliates) pursuant to Facility Agreements (as defined in
                      the  Agreement)  in the  calendar  year  leading up to the
                      relevant  Measurement  Date (inclusive of such Measurement
                      Date and, in the


                                      1-2


                      instance of the first  Measurement Date  (12/31/96),  from
                      and  including  the  Effective  Date  (as  defined  in the
                      Agreement)  through  such  first  Measurement  Date - each
                      period being herein referred to as an "Interval"); LESS

                 (ii) the sum of (a) plus (b) where:

                  (a)  =  the  aggregate  amount  of  any  reasonable  operating
                  expenses  (excluding,  without limitation,  any allocation for
                  overhead)  incurred by the Partner  (or its  affiliates)  with
                  respect to such revenue (also  consistent  with the accounting
                  principles consistently applied by the Partner with respect to
                  its component of the financial statements of the Company filed
                  with the SEC) in the applicable Interval; and

                  (b) = the  aggregate  amount  of (x)  the sum of  twenty  (20)
                  percent of the "Interval Value" (as defined below) for each of
                  the prior Measurement Dates (if any and subject, in any event,
                  to a maximum  of four)  plus (y)  twenty  (20)  percent of the
                  Interval Value for the Measurement Date at issue.1


To calculate  Pre-Tax Net Income (and otherwise  provide a mechanism whereby the
parties to the Agreement are able to monitor the Association's activities),  the
Partner will prepare or cause to be prepared:

(1)      separate  consolidated  monthly  statements setting forth total revenue
         (pursuant to clause (i) above) and related

___________

1 The intent of using a twenty (20) percent figure and a five-year  period is to
apply the  "charge"  for any given  Interval  Value over a period of five years;
however,  to the extent any such charge (or portion thereof) is thereby extended
beyond the last Measurement Date, the effect of such charge (or portion thereof)
shall not impact the formula.

         An example of the application of Interval Value to the determination of
Pre-Tax  Net  Income  is as  follows:  if,  as of  the  third  Measurement  Date
(12/31/98),  the Interval Value for the first  Measurement  Date  (12/31/96) was
determined (in connection with the vesting of the first Tranche of Shares) to be
$100,000 and the Interval Value for the second  Measurement  Date (12/31/97) was
determined (in  connection  with the vesting of the second Tranche of Shares) to
be $60,000,  then the amounts of $20,000 (20% of the first  Interval  Value) and
$12,000  (20% of the second  Interval  Value) would be added to 20% of the third
Interval  Value (the amount of which will depend upon the results of the formula
of this Schedule 1,  including  solving for the third  Interval Value itself) to
derive  "(b)" for  purposes  of clause  (ii) of the  definition  of Pre-Tax  Net
Income.

         operating expenses (pursuant to clause (ii)(a) above) and an additional
         monthly statement for each venture or relationship  between the Partner
         (or its affiliates) and any Facility(ies) (as defined in the Agreement)
         involving equity ownership;

(2)      combined  statements,  over  the  period  of each  Interval,  for  each
         specific   venture  or   relationship   between  the  Partner  (or  its
         affiliates) and any Facility(ies); and

(3)      following each Interval,  a sufficiently  detailed calculation prepared
         by the independent  accounting firm used by the Partner with respect to
         its public reporting (a "Calculation"),  with respect to the Interval's
         ending  Measurement  Date, of the value of the Warrant as it relates to
         the Tranche of Shares which shall vest pursuant to the Warrant and this
         Schedule 1 as of such  Measurement  Date (which value,  with respect to
         each Measurement Date, is referred to herein as the "Interval Value").2

         Monthly  statements shall be distributed by the Partner to the Investor
within sixty (60) days after the applicable  month-end,  and Interval statements
(which  shall  include the relevant  Calculation)  shall be  distributed  by the
Partner to the  Investor  within  sixty (60) days  after the  Interval's  ending
Measurement Date.

         Notwithstanding  any  Calculation,  the  Investor may elect to have the
Interval Value as of any Measurement  Date determined (a  "Determination")  by a
third party (e.g., an independent accounting firm, an investment banking firm or
another person or entity reasonably  competent to perform a Determination) which
third party shall be reasonably  acceptable to the Company.  Such election shall
be made by the Investor,  with respect to any Measurement  Date,  within 30 days
after the Investor shall have been advised,  in writing,  of the Calculation for
such Measurement Date.  Thereafter,  the parties shall be bound, for purposes of
the  Interval  Value for any  Measurement  Date,  by the lesser of the amount of
Interval Value derived from (i) the  Determination or (ii) the Calculation.  The
Company and the Investor shall each bear  responsibility  for fifty (50) percent
of the fees and expenses of the third party making any

____________

2 Each Calculation shall be performed using the Black-Scholes formula (with such
assumptions as the Partner can reasonably support (e.g., assumptions used by the
Company  with  respect to public  reporting  of the value of options  granted to
executives and/or employees of the Company and/or its affiliates)).

         In the event that any Calculation  produces an Interval Value which the
independent accounting firm producing such Calculation determines is immaterial,
the Interval Value at issue shall be deemed to be $0.00.

Determination;  however,  each of the Company and the Investor  shall have equal
access to the  personnel  and working  papers  involved in or  pertinent  to the
Determination.

         The Partner shall keep complete and proper  records and accounts of all
Association-related operations in sufficient detail to enable Pre-Tax Net Income
to be determined for each month and Interval.  The Investor shall have the right
to appoint an independent  certified public accounting firm to audit the records
of the Partner  and/or the Company as  necessary to verify the amount of Pre-Tax
Net Income set forth in any monthly or Interval  statement.  Such audit shall be
at the Investor's expense;  provided,  however, that if the audit discloses that
Pre-Tax Net Income,  as calculated by the Partner,  is deficient for the related
period by at least five  percent  (5%),  then the Partner  shall  reimburse  the
Investor  for any such audit  costs and  expenses.  The  Partner and the Company
shall  preserve  and  maintain all such records as may be necessary or advisable
for  review  in the  course  of such an audit  for a period  of three  (3) years
following the final Measurement Date (12/31/00).

Measurement Date/Conversion Ratio

         The applicable conversion ratio for each Measurement Date (to insert as
the  "Ratiomd"  for purposes of the formula set forth above) shall be determined
as follows:

         Measurement Date                   Conversion Ratio
         ----------------                   ----------------

         12/31/96                             [CONFIDENTIAL TREATMENT REQUESTED]
         12/31/97                             [CONFIDENTIAL TREATMENT REQUESTED]
         12/31/98                             [CONFIDENTIAL TREATMENT REQUESTED]
         12/31/99                             [CONFIDENTIAL TREATMENT REQUESTED]
         12/31/00                             [CONFIDENTIAL TREATMENT REQUESTED]


Example of Calculation

         If, in the Interval  from  12/31/97 to 12/31/98,  Pre-Tax Net Income is
$1,000,000  and 100,000  Shares have  previously  vested under the Warrant,  the
number of Shares (comprising the Tranche of Shares for the 12/31/98  Measurement
Date) which shall vest as of the 12/31/98  Measurement  Date shall be calculated
as follows:

         SV12/31/98 = (1,000,000/[CONFIDENTIAL TREATMENT REQUESTED]) - 100,000

         or [CONFIDENTIAL TREATMENT REQUESTED] Shares vesting as of the 12/31/98
         Measurement Date.
