         2.1  Mariner   Obligations.   Each  of  the  Mariner   Entities  hereby
acknowledges  that,  subject to the  effect of the  filing of the  Cases,  it is
unconditionally  liable  to  SPTMNR  for the  full  and  immediate  payment  and
performance of each of the  obligations  under the terms of the Master Lease and
the other  documents,  instruments and agreements  listed in Schedule 2.1 hereto
(collectively,  the "Existing Documents"), plus all charges that may arise under
the various  documents  executed  or  delivered  by any of the Mariner  Entities
evidencing  or  relating  to such  obligations,  plus all  costs  of  collection
incurred  in  connection  with  such  obligations  by the SNH  Entities  and the
reasonable  fees  and  expenses  incurred  by  attorneys  for the  SNH  Entities

Obligations"),  and  that  none  of  the  Mariner  Entities  has  any  defenses,
counterclaims or set-offs with respect to the full and immediate  payment of any
or all of the Existing Mariner  Obligations other than as may arise by reason of
the filing of the Cases.

"Transaction  Approval  Motion"),  together  with a proposed  form of order (the
"Approval  Order") and the Approval  Order shall be in a form,  and include such
provisions,  as the SNH Entities and the Mariner  Entities may deem  appropriate
under the circumstances.

                                    ARTICLE 3

                   TRANSACTIONS TO OCCUR AT THE EFFECTIVE TIME

         At the Effective  Time,  the parties  hereto shall effect the following
transactions:

         3.1 Surrender of Master Lease.  AMS Properties and GCIHCC shall assume,
assign  and  surrender  to the New  Operator  designated  by  SPTMNR  all of AMS
Properties' and GCIHCC's  right,  title and interest in, to and under the Master
Lease,  and such New  Operator  shall  accept  such  assignment  and  surrender,
whereupon all of AMS Properties' and GCIHCC's rights and obligations  thereunder
(and the  rights and  obligations  of the  Mariner  Entities  under the  Mariner
Entities'   Guaranties)  shall  terminate.   All  cure  payments   allocable  to
pre-Petition Date periods will be waived.

         3.2 Transfer of Personal  Property,  Etc. AMS Properties  and/or GCIHCC

computer  equipment)  and,  subject to and upon the terms and  conditions of any
applicable  licensing  agreements with respect  thereto,  all software and other
software  licenses  used in the  normal  course of  business  operations  at the
Retained  Facilities.  The SNH Entities  acknowledge and agree that the terms of
certain site  licenses  entered into between the Mariner  Entities and Microsoft
Corporation and other software  licenses for  non-proprietary  software prohibit
the assignment  and transfer of those licenses to the SNH Entities.  The Mariner
Entities and the SNH Entities further agree to enter into licensing  agreements,
in a form and substance  reasonably  satisfactory to both parties, to permit the
SNH  Entities  to use and  operate  certain  clinical  software  which  has been
internally  developed by the Mariner  Entities to assist in the operation of the
Retained Facilities including, without limitation, those software programs which
are used to track the Minimum Data Set of Medicaid  Statistics  for each patient
in the Retained Facilities.

         3.3.  Transfer of Contracts and Permits.  AMS Properties  and/or GCIHCC
(as  applicable)  shall  assume and  assign,  set over and  transfer  to the New
Manager or New Operator all of their right, title and interest in and to (i) all
of the Subleases  (other than the right,  title and interest of GCIHCC in and to
the Tenant  Purchase and Sale Agreement  referred to in each of the South Dakota
Subleases,  or in and to any promissory note delivered by any Subtenant pursuant
thereto or otherwise  delivered in connection with any such Subleases),  (ii) to
the extent  permitted  by law,  all of the Permits  with respect to the Retained
Facilities that the New Manager or the New Operators elect to assume,  and (iii)
all of the  Contracts  with  respect  to the  Retained  Facilities  that the New
Manager or the New Operators elect to assume as provided in Section 10.7 hereof,
but specifically  excluding,  in each of the immediately  preceding clauses (i),
(ii)  and  (iii)  any  Pre-Closing  Obligations  (except,  in  the  case  of the
Contracts, as otherwise provided in Section 10.7 hereof).

thereof,  and the SNH Entities shall release to GranCare,  free and clear of all
liens, claims and encumbrances  arising by, through or under any SNH Entity, any
pledges of any stock of AMS  Properties or GCIHCC or other  collateral  securing
the Master Lease or any related guaranties,  including,  without limitation, any
interest in accounts receivable arising prior to the Effective Time.

Operators  shall  enter  into  an  interim  management  agreement  (an  "Interim
Management  Agreement"),  substantially  in the form attached as Schedule  3.5-A
hereto,  with  respect to the  Retained  Facilities  with the New Manager  under
which,  to the  extent  and  subject to the  limitations  imposed by  applicable
licensure and certificate or determination  of need laws and  regulations,  each
Mariner Operator shall agree to perform certain  management  services  described
therein with respect to the operation of the Retained Facilities and, subject to
the control and direction of the Mariner Operators,  as current  licensees,  the
New Manager may assume  responsibility  for  certain of such  services,  pending
receipt  by the New  Manager  and/or  New  Operator,  as the case may be, of all
licenses,  certificates,  permits  and  approvals  necessary  to  assume  direct
operating  control of such Retained  Facility.  The Mariner Operators also shall
enter into an interim occupancy  agreement (an "Interim  Occupancy  Agreement"),
substantially  in the form attached at Schedule  3.5-B  hereto,  with respect to
each of the Retained  Facilities with the appropriate New Operator,  which shall
provide that during the term of such Interim Occupancy  Agreement,  such Mariner
Operator shall  continue to occupy such Retained  Facility and have such control
over such Retained Facility as is necessary to comply with applicable  licensure
and certificate of need statutes and regulations.

         3.6  Conveyance of  Transferred  Facilities.  Each SNH Entity shall (i)
convey all of its respective  right,  title and interest,  if any, in and to the
parcels  of  real  property   described  in  Schedule  3.6,  together  with  all
improvements  thereon  (collectively,  the  "Transferred  Real Estate"),  to AMS

used in  connection  with the operation of the nursing  facility  located on the
Transferred  Real Estate,  in each case free and clear of all liens,  claims and
encumbrances,   except  Permitted  Encumbrances.   All  deeds,  bills  of  sale,
assignments  and other  instruments of transfer or releases  necessary to effect
such   conveyances   shall   expressly   state   that  they  are  made   without
representations  and  warranties,  express or implied,  except as expressly  set
forth in this Agreement.

         3.7 Bankruptcy Code Provisions.  Each of the transactions  provided for
in Sections 3.1,  3.2,  3.3, 3.4 and 3.5 shall be completed in  accordance  with
Sections 105, 363(b),  (f), and (m), and 365 and 1146(c) of the Bankruptcy Code,
as applicable,  and the provisions of the Approval Order,  with the SNH Entities

                                   ARTICLE 10

              CERTAIN MATTERS RELATING TO TRANSITION OF PROPERTIES

         10.1 Employees; Employee Benefits.

         10.1.1 After the Effective Time and subject to the terms of the Interim
Management  Agreement,  the Mariner Entities shall employ qualified nursing home
administrators who shall be responsible for the functional  day-to-day operation
of the  Retained  Facilities  and  supervision  of  personnel  at  the  Retained
Facilities,  as well  as all  on-site  professional,  custodial,  food  service,
cleaning,   maintenance,   clerical,   secretarial,   bookkeeping,   management,
collection,  and other  employees for the day-to-day  operations of the Retained
Facilities.  All such  administrators  and other personnel shall be employees of
the Mariner Entities.

         Notwithstanding  the foregoing,  the New Manager shall offer employment
to all or substantially  all of the qualified  nursing home  administrators  and
other  employees at the Retained  Facilities as soon after the Effective Time as
is reasonably practicable.  The Mariner Entities acknowledge that the ability of
the New Manager to make any such offer is contingent  upon the  employees  being
employable  under state and Federal law and may be subject to the New Operators'
or New Manager's receipt of all licenses,  permits,  approvals,  authorizations,
provider  agreements,  and  certificates  and  determinations  of  need  as  are
necessary for the New Operators and the New Manager to operate the Facilities as
licensees and to receive  Medicare and Medicaid  reimbursement  for the services
provided  therein,  and that in any event the New  Manager  will  first  have to
implement an appropriate  accounting and payroll function.  The Mariner Entities
further  acknowledge that the New Manager may not hire all such employees on the
same date or at the same time. The Mariner  Entities agree to cooperate with the
New  Manager in  connection  with such offers of  employment  and to release any
personnel  to  whom  the New  Manager  offers  employment  from  any  employment
agreements,  non-competition,  non-solicitation and non-disclosure agreements or
common law obligations relating to their employment with the Mariner Entities to
which they may be a party or subject.

         10.1.2  Payroll and payroll  related  costs shall be prorated as of the
Effective Time.

         In addition, the Mariner Entities shall pay to the New Manager for each
Facility an amount of cash  equivalent to all Employee  Accruals with respect to
such Retained Facility at the Effective Time and, in connection  therewith,  the
SNH Entities shall assume the Mariner Entities' obligation to pay the same.

         AMS Properties,  GCIHCC, or the New Manager,  as the case may be, shall
pay all payroll and payroll related costs, and maintain, prepare and process all
employee  payroll records and tax withholding  filings,  relating to, or arising
out of, any employee's employment from and after the Effective Date, as provided
in the Interim Management Agreement.



                                      -25-


         The  Mariner  Operator  of  each  Retained  Facility  shall,  as of the
Effective Time,  deliver to the New Manager all personnel  records for employees
at such Retained Facility.  Each Mariner Operator shall have the right to retain
copies  of any  files  which  are  delivered  to the New  Manager.  The  Mariner
Operators,  the New  Operators  and the New  Manager,  as the case may be,  each
further  acknowledge  and agree that, in order to facilitate the  application of
the proration  provisions of this Section 10.1, they shall generate  terminating
payrolls and make  corresponding  payments to employees with respect thereto for
each  Retained  Facility  on both the  Effective  Date and the date that the New
Manager  shall hire all or  substantially  all of the employees at such Retained
Facility.

         10.2 Prorations.

                  10.2.1  Revenues and expenses  pertaining to Contracts (to the
extent  applicable),  utility  charges  for the  billing  period  in  which  the
Effective Time occurs,  prepaid expenses,  real estate taxes, municipal charges,
payroll,  Employee  Accruals and Employee  Benefits and other  related  items of
revenue or expense  attributable  to any  Retained  Facility  shall be  prorated
between the Mariner  Operator  for such  Retained  Facility and the relevant New
Operator as of the Effective Time. In general,  such prorations shall be made so
as to reimburse such Mariner  Operator for prepaid expense items,  and to charge
the relevant  Mariner Operator for prepaid revenue items, to the extent that the
same are attributable to periods after the Effective Time.

                  10.2.2  All  such  prorations  shall  be made on the  basis of
actual days elapsed in the relevant  accounting or revenue period and (i) in the
case of utility charges, real estate taxes, municipal charges, payroll, Employee
Accruals and Employee  Benefits,  shall be calculated  and paid at the Effective
Time as provided  in Section  10.2.3  hereof,  based on  invoices,  remittances,
statements and other information available with respect to such charges, and, if
such invoices,  remittances,  statements and other information are not available
with  respect to such  charges,  on  estimates  based on prior  charges for such
items,  (ii) in the case of all Contracts (to the extent  applicable)  and other
items of revenue or expense  attributable  to any  Retained  Facility,  shall be
calculated  and paid on the date that is the sixtieth  (60th) day (the  "True-Up
Time") after the Effective Time, as provided in Section 10.2.3 hereof,  based on
invoices,  remittances,  statements  and other  information  then available with
respect to such charges,  and, if such  invoices,  remittances,  statements  and
other  information  continue to be unavailable with respect to such charges,  on
estimates  based on prior  charges for such items,  and (iii) to the extent that
any  prorations for payments and charges  outlined in the preceding  clauses (i)
and (ii) are based on estimates, the SNH Entities and the Mariner Entities agree
to reconcile the  estimates for such items against the actual costs  therefor by
no later than  September  30, 2000.  The SNH  Entities and the Mariner  Entities
agree  that the  calculation  of the  proration  at the  True-Up  Time  shall be
performed by Ernst & Young U.S.  LLP and that they shall each pay fifty  percent
(50%) of the cost therefor. Notwithstanding anything contained in this Agreement
to the contrary, the SNH Entities shall be obligated to make payment for amounts
it collects on account of any prorations paid to the SNH Entities by the Mariner
Entities in accordance with this Section 10.2.

                  10.2.3 The  accounts of the Mariner  Entities and SNH Entities
created pursuant hereto shall be netted against each other. If (i) the result is
a net positive balance for the



                                      -26-


Mariner Entities,  the SNH Entities shall pay to the Mariner Entities the amount
of such  balance by  corporate  check,  and (ii) if the result is a net positive
balance  for the SNH  Entities,  the  Mariner  Entities  shall pay to SPTMNR the
amount of such balance by corporate check.

                  10.2.4  There  shall  be no  prorations  with  respect  to the
Transferred  Facilities  (other  than with  respect  to rent and  other  amounts
payable  under the  Master  Lease),  as all such  expenses  with  respect to the
Transferred  Facilities are the  responsibility of the Mariner Entities prior to
the Effective Time, as lessee under the Master Lease,  and thereafter,  as owner
of the Transferred Facilities.

         10.3 Accounts  Receivable.  From and after the Effective  Time, (i) the
New Operators shall, to the extent permitted by applicable law, own all accounts
receivable  which  relate  to or arise  out of  services  provided  by or at the
Retained Facilities from or after the Effective Time (the "Post-Effective A/R"),
(ii)  the  Mariner   Operators   shall  make  and  effect   collections  of  all
Post-Effective  A/R,  (iii)  the  Mariner  Operators  shall  establish  new bank
accounts (the "New A/R  Accounts") in the name of each Mariner  Operator at such
local banks to be agreed upon by the SNH Entities and the Mariner Entities,  and
shall  instruct all Third Party Payors and other Persons that  directly  deposit
monies into the existing  bank  accounts  (the  "Existing  A/R  Accounts")  with
respect to the Retained Facilities to terminate such direct deposit and commence
depositing such monies into the New A/R Accounts from and after the date that is
sixty (60) days after the  Effective  Time (the "Account  Transfer  Time") or as
soon as is  practicable  thereafter  (and the Mariner  Entities  shall take such
further  action as may be reasonably  necessary to cause such Third Party Payors
and other Persons to comply with such  instructions  so that all  Post-Effective
A/R are deposited into the New A/R Accounts from and after the Account  Transfer
Time or as soon as is practicable thereafter),  (iv) the Mariner Operators shall
continue to endorse and deposit all monies,  checks, drafts or other instruments
or items  received as payment  for any  Post-Effective  A/R with  respect to any
Facility into the Existing A/R Accounts until the Account Transfer Time, (v) the
Mariner Operators shall endorse and deposit all monies,  checks, drafts or other
instruments  or items  received as payment for any  Post-Effective  A/R from and
after the Account Transfer Time into the New A/R Accounts,  (vi) within five (5)
days of the New Operators request therefor (but no sooner than the SNH Licensing
Date),  the Mariner  Operators  shall assign,  set over and transfer the New A/R
Accounts to the New Operators, and (vii) the Mariner Entities shall disburse all
proceeds  attributable  to  Post-Effective  A/R  deposited  in the  Existing A/R
Accounts or the New A/R  Accounts or  otherwise  received or held by the Mariner
Entities to the SNH  Entities  (or to such other  Person as the SNH Entities may
direct) within five (5) days of the Mariner Entities' receipt thereof.

         The SNH Entities and the Mariner  Entities  acknowledge  and agree that
(i) the Mariner  Entities  shall continue to own all accounts  receivable  which
relate to or arise out of  services  provided by or at the  Retained  Facilities
prior to the Effective Time (the "Pre-Effective A/R"), (ii) the Mariner Entities
shall be entitled  to retain all  proceeds  attributable  to  Pre-Effective  A/R
deposited  in the  Existing  A/R  Accounts or the New A/R  Accounts or otherwise
received  or held by the  Mariner  Entities,  and (iii) the SNH  Entities  shall
disburse  to the  Mariner  Entities  (or to



                                      -27-


such other Person as the Mariner Entities may direct) all such Pre-Effective A/R
within five (5) days of the SNH Entities' receipt thereof.

         10.4 No Assumption  of  Liabilities.  Notwithstanding  anything in this
Agreement or elsewhere to the  contrary,  no SNH Entity is assuming,  and no SNH
Entity shall be  responsible  for, any  liability of any kind or nature  whether
known or unknown, absolute, mature or not yet due, liquidated or non-liquidated,
contingent,  non-contingent,  direct or  indirect or  otherwise,  of any Mariner
Entity or any other person for:

                  (a) Any costs or  expenses,  including,  but not  limited  to,

         Entity or its or his employees,  agents or representatives or any other
         person  performing  services for or on behalf of any Mariner Entity (i)
         with respect to the Retained  Facilities,  prior to the Effective  Time
         and,  subject to, and upon the terms and  conditions  contained  in the
         Interim Management  Agreement,  after the Effective Time, and (ii) with
         respect to the  Transferred  Facilities or any other  operations of the

         or  judgment   retroactively   adjusting   the   amounts   payable  for
         reimbursement purposes or recovering overpayments made or requiring the
         payment of fines,  penalties or damages,  or  reduction of  prospective
         payments to any Facility or  interest,  with respect to, or based upon,
         the  services  rendered by any Mariner  Entity (i) with  respect to the
         Retained  Facilities,  prior to the Effective Time and, subject to, and

extent provided for in the Master Lease). The SNH Entities shall, in addition to

intended by the  parties  hereto  that if the New  Operators  elect to cause the
Mariner  Entities to assume and assign any such Contract in accordance with this
Section  10.7,  the New Operators  will pay any cure amounts  required to effect

                                    RELEASES

         12.1 Release of SNH  Entities.  Subject to, and in  consideration  for,
each SNH Entity entering into this Agreement and  consummating  the transactions
contemplated  hereby,  each Mariner Entity shall release and forever  discharge,
each SNH Entity and their respective successors,  assigns, agents, shareholders,
directors,   officers,   employees,   agents,  attorneys,  parent  corporations,
subsidiary corporations, affiliated corporations,  affiliates, and each of them,
from  any and all  claims,  debts,  liabilities,  demands,  obligations,  costs,
expenses, actions



                                      -31-


and causes of action, of every nature and description, whether known or unknown,
absolute,  mature,  or not yet due,  liquidated or  non-liquidated,  contingent,
non-contingent,  direct or indirect or otherwise,  which any Mariner  Entity now
has or at any time may hold, by reason of any matter,  cause or thing  occurred,
done,  omitted or suffered to be done on or prior to the  Effective  Time.  Each
Mariner  Entity waives the benefits of any law,  which may provide in substance:
"A general release does not extend to claims which the creditor does not know or
suspect to exist in his favor at the time of  executing  the  release,  which if
known by him must have materially affected his settlement with the debtor." Each
Mariner  Entity  understands  that the facts which it believes to be true at the
time of  making  the  release  provided  for  herein  may  later  turn out to be
different than it believes now or at the time of granting such release, and that
information which is not now or then known or suspected may later be discovered.
Each Mariner  Entity accepts this  possibility,  and each Mariner Entity assumes
the risk of the facts  turning out to be  different  and new  information  being
discovered; and each Mariner Entity further agrees that the release provided for
herein  shall in all  respects  continue  to be  effective  and not  subject  to
termination  or  rescission  because of any  difference in such facts or any new
information.

         Notwithstanding anything to the contrary contained in this Section 14.1
or  otherwise,  this release  shall only be effective on and as of the Effective
Time and specifically  only upon the  consummation of the transactions  provided
for in this Agreement and not otherwise.

         None of the  Mariner  Entities  is  releasing  any SNH Entity  from any
claims, debts, liabilities,  demands,  obligations,  costs, expenses, actions or
causes of action arising out of this Agreement,  any Settlement  Document or the
transactions  contemplated  hereby, or otherwise,  except as expressly  provided
herein.

         12.2 Release of Mariner Entities.  Subject to, and in consideration for
each  Mariner  Entity  entering  into  this  Agreement  and   consummating   the
transactions  contemplated  hereby,  each SNH Entity  shall  release and forever
discharge each Mariner Entity and their respective successors,  assigns, agents,
shareholders,   directors,   officers,   employees,  agents,  attorneys,  parent
corporations, subsidiary corporations, affiliated corporations,  affiliates, and
each of them, from any and all claims, debts, liabilities, demands, obligations,
costs, expenses,  actions and causes of action, of every nature and description,
whether known or unknown,  which any SNH Entity now has or at any time may hold,
by reason of any matter,  cause or thing occurred,  done, omitted or suffered to
be done on or prior to the Effective  Time.  Each SNH Entity waives the benefits
of any law, which may provide in substance:  "A general  release does not extend
to claims which the  creditor  does not know or suspect to exist in his favor at
the time of executing  the release,  which if known by him must have  materially
affected his settlement with the debtor." Each SNH Entity  understands  that the
facts which it  believes  to be true at the time of making the release  provided
for herein may later turn out to be  different  than it  believes  now or at the
time of granting such  release,  and that  information  which is not now or then
known or  suspected  may  later be  discovered.  Each SNH  Entity  accepts  this
possibility, and each SNH Entity assumes the risk of the facts turning out to be
different and new  information  being  discovered;  and each SNH Entity  further
agrees that the release provided for herein shall in all



                                      -32-


respects  continue to be effective and not subject to  termination or rescission
because of any difference in such facts or any new information.

         Notwithstanding anything to the contrary contained in this Section 14.2
or  otherwise,  this release  shall only be effective on and as of the Effective
Time and specifically  only upon the  consummation of the transactions  provided
for in this Agreement and not otherwise.

         None of the SNH  Entities  is  releasing  any  Mariner  Entity from any
claims, debts, liabilities,  demands,  obligations,  costs, expenses, actions or
causes of action arising out of this Agreement,  any Settlement  Document or the
transactions  contemplated  hereby, or otherwise,  except as expressly  provided
herein.

         12.3 No  Further  Commitments  by SNH  Entities.  Each  Mariner  Entity
further  acknowledges that, from and after the Effective Time, no SNH Entity has
any existing commitments, obligations or agreements to advance credits or loans,
or to lease property,  or make financial or other  accommodations to any Mariner
Entity,  except  as may be  specifically  set  forth  in this  Agreement  or the
Settlement Documents.

CONDUCT,  ACTS OR  OMISSIONS  OF ANY  PARTY  HERETO  OR ANY OF THEIR  DIRECTORS,
TRUSTEES, OFFICERS, EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED
WITH THEM; IN EACH OF THE FOREGOING CASES,  WHETHER SOUNDING IN CONTRACT OR TORT
OR OTHERWISE.

         13.2  Survival.  Except as otherwise  provided by this  Agreement,  all
covenants,  agreements,  representations  and  warranties  made by each  Mariner
Entity or SNH  Entity  herein  and in all  certificates  and  other  instruments
delivered pursuant to this Agreement shall survive the execution and delivery of
the deeds to the  Transferred  Facilities  and the  closing of the  transactions
contemplated  hereby,  and the Mariner  Entities  shall be and remain liable for
breaches of the provisions of this Agreement,  the Interim Management  Agreement
and the Interim  Occupancy  Agreements,  contravention  of the Approval Order or
otherwise  for the  period  including  the  greater  of one (1) year or the last
administrative claims bar date that is established by order of the Court (except
that the SNH Entities shall in all events remain liable to the Mariner  Entities
for the amount of any  deductible  or  self-insured  retention  amounts  paid or
payable  under Section  5.1(a) of the Interim  Management  Agreement  until such
deductible or  self-insured  retention  amounts shall have been paid). If and to

         WHEREAS, the Proposed SNH Licensees and the Mariner Licensees desire to
enter into certain arrangements  regarding the management of the Facilities and,
more  specifically,  to  provide  for  the  Mariner  Licensees  to  operate  the
Facilities  pending,  and in  anticipation  of, the receipt by the  Proposed SNH
Licensees  or the  Manager  of the  Necessary  Licenses  (the  date on which any
Proposed SNH  Licensee or the Manager  shall have  received  all such  Necessary


Licenses with respect to a Facility being referred to herein as such  Facility's
"SNH  Licensing  Date"),  and to consult and  cooperate  with the  Proposed  SNH
Licensees' designee, the Manager, in connection therewith;

         NOW,  THEREFORE,  for and in consideration of the premises,  the mutual
covenants  and  agreements   herein   contained  and  other  good  and  valuable
consideration,  the receipt and adequacy of which are hereby  acknowledged,  the
parties hereto agree as follows:

1. Mariner Licensee; Interim Occupancy Agreements.  Each Facility shall continue
to be operated  subject to the  direction  and control of the  relevant  Mariner
Licensee until such Facility's SNH Licensing Date and, in connection  therewith,
each  such  Mariner  Licensee  (i)  shall  retain  ultimate  authority  over the
business, policies, operations and assets of the Facility, (ii) shall remain the
responsible  licensee of such Facility and, as such, be fully liable and legally
accountable  at all  times to all  patients,  governmental  agencies  and  third
parties for all patient care and funds,  and all other  aspects of the operation
and  maintenance  of the  Facility,  and (iii) shall  perform  those general and
specific duties described in Sections 2 and 3 hereof.

         In  order  to  permit  the   foregoing,   each  Mariner   Licensee  is,
simultaneously   herewith,   entering  into  an  Interim   Occupancy   Agreement
(collectively,  the  "Occupancy  Agreements"),  [in the form attached  hereto as
Schedule C,] with the  relevant  Proposed  SNH  Licensee,  pursuant to which the
Proposed SNH Licensee  shall grant to such Mariner  Licensee the right to occupy
such  Facility  and use  certain  related  personal  property  for  purposes  of
exercising its rights, duties and obligations hereunder.

         The Mariner Licensees, the Proposed SNH Licensees and the Manager agree
that,  subject in all events to the  provisions  of the first  paragraph of this
Section 1, the SNH  Proposed  Licensees  or the  Manager  may from time to time,
notify the Mariner  Licensees that the Manager is prepared to provide any one or
more of those  services  (the  "Designated  Services")  designated in Schedule D
attached hereto (the "Designated Services Schedule"), with respect to any one or
more of the  Facilities,  and from and after the date  specified in such notice,
the Mariner  Licensee shall delegate to Manager and the Manager shall assume and
perform  such  Designated  Services.  The Mariner  Licensees,  the  Proposed SNH
Licensees and the Manager shall  reasonably  cooperate in the  transition of the
responsibility  for such  Designated  Service(s) to the Manager,  subject to the
continued  authority  and  responsibility  of the Mariner  Licensee  referred to
herein.

         The Mariner  Licensees,  the  Proposed  SNH  Licensees  and the Manager
acknowledge  and agree that the Mariner  Licensees have agreed in this Agreement
that the Mariner  Licensees may continue to provide  certain  services after the
SNH Licensing  Date. The Mariner  Licensees,  the Proposed SNH Licensees and the
Manager acknowledge and agree,  however,  that, from and after the SNH Licensing
Date with respect to a Facility, the relevant Proposed SNH Licensee shall direct
and control the operations of such Facility and, in connection therewith,  shall
have ultimate authority over the business, policies, operation and assets of the
Facility and be the responsible licensee of such Facility and, as such, be fully
liable and legally  accountable  at all times to all patients  and  governmental
agencies for all patient care and funds at such Facility,  and all other aspects
of the operation and maintenance of such Facility.

3. Specific  Duties.  The Mariner  Licensees  shall have the following  specific
duties:

         3.1  Employees.  The Mariner  Licensees  shall recruit,  evaluate,  and
select qualified  nursing home  administrators  who shall be responsible for the
functional  operation  of the  Facilities  and  supervision  of personnel at the
Facilities,  on a  day-to-day  basis,  as  well  as  all  on-site  professional,
custodial,  food  service,   cleaning,   maintenance,   clerical,   secretarial,
bookkeeping,  management,  collection,  and other  employees for the  day-to-day
operations of the Facilities.  Such  administrators and all such other personnel
shall be employees of the Mariner  Licensees,  and, subject to the provisions of
Section 5 hereof  (providing  for the Proposed SNH Licensees to pay expenses set
forth in the Expense Statement  (including,  without limitation,  those expenses
specified   in  Section   5.1(a))   the  Mariner   Licensees   shall  have  full
responsibility for payment of their wages,  salaries, and other compensation and
benefits.  The Mariner Licensees shall establish such personnel  policies,  wage
structures,  and  staff  schedules  as they

                                      -3-


deem  necessary  and advisable in accordance  with  applicable  law. The Mariner
Licensees shall have authority to continue to employ and to discharge employees.
The Mariner  Licensees  shall  maintain  payroll  records and shall  prepare and
process employee  payrolls,  and returns of withholding taxes in accordance with
current payroll schedules in place at each Facility.

         Anything  in this  Section  3.1 to the  contrary  notwithstanding,  the
Manager  shall offer  employment  to all or  substantially  all of the qualified
nursing home  administrators and other employees at the Facilities as soon after
the  Effective  Time  as  is  reasonably  practicable.   The  Mariner  Licensees
acknowledge that the ability of the Manager to make any such offer is contingent
upon the  employees  being  employable  under  state and  Federal law and may be
subject  to the  Proposed  SNH  Licensees'  and  the  Manager's  receipt  of all
licenses,   permits,   approvals,   authorizations,   provider  agreements,  and
certificates  and  determinations  of need as are necessary for the Proposed SNH
Licensees and the Manager to operate the  Facilities as licensees and to receive
Medicare and Medicaid  reimbursement for the services provided therein, and that
in any event the Manager will first have to implement an appropriate  accounting
and payroll function. The Mariner Licensees further acknowledge that the Manager
may not hire all  such  employees  on the  same  date or at the same  time.  The
Mariner  Licensees  agree to cooperate with the Manager in connection  with such
offers of  employment  and to release any  personnel to whom the Manager  offers
employment from any employment agreements, non-competition, non-solicitation and
non-disclosure agreements or common law obligations relating to their employment
with the Mariner Licensees to which they may be a party or subject.

         3.2  Purchasing.  The Mariner  Licensees  shall  (subject to Section 5)
purchase,  in the name, and for the account, of the Proposed SNH Licensees,  all
necessary  supplies,  foodstuffs,  materials,  appliances,  tools, and equipment
customarily used in the operation of the Facilities. The Mariner Licensees shall
use  commercially  reasonable  efforts to limit purchasing costs and to maintain
such costs at a level  reasonably  calculated to allow the Facilities to operate
profitably.  The Mariner Licensees may, but shall not be obligated to, make such
purchases in bulk under a centralized  purchasing system established by them for
other facilities under their operation or management in order to minimize costs.
The Mariner Licensees shall arrange contracts for electricity,  gas,  telephone,
and any other utility or service  necessary to the operation of the  Facilities,
in each case in the name,  and for the account,  of the Proposed SNH  Licensees.
The Mariner  Licensees  shall, on their own behalf and/or on behalf of the owner
of the buildings and real  property in and on which the  Facilities  are located
(the  "Real  Property  Owner"),  contract  for and  supervise  the making of any
necessary  repairs,  alterations,  and improvements to the Facilities,  provided
that in the case of any repair,  alteration  or  improvement,  the cost of which
exceeds  $5,000,  the Mariner  Licensees  shall obtain the prior approval of the
Proposed  SNH  Licensee/Manager,  except  that no such prior  approval  shall be
required if the  expenditure is made under  circumstances  reasonably  requiring
emergency action. The Mariner Licensees shall prepare such  certifications as to
expenses incurred in the operation of the Facilities as may be required in order
to comply with applicable law and regulations,  including,  without  limitation,
law and regulations applicable to preparation and submission of cost reports.

         3.3 Bookkeeping.  The Mariner  Licensees shall establish and maintain a
record and bookkeeping system for the operation and conduct of the Facilities in
accordance with generally accepted accounting principles.  Full books of account
with entries of all receipts and

                                      -4-


expenditures of the Facilities  shall be open for inspection by  representatives
of Proposed SNH Licensees and Manager upon  reasonable  notice and at reasonable
times.

         3.4 Financial  Reports.  The Mariner  Licensees  shall:  (a) as soon as
reasonably  possible  after the close of each  calendar  month,  furnish  to the
Proposed  SNH  Licensee  and Manager a statement of income for the month and for
the year to date, together with a detailed statement of billings, cash receipts,
cash disbursements,  accounts payable and accounts receivable (in hard copy and,
to the extent possible, in electronic format); (b) in the event the Proposed SNH
Licensee or Mariner  Licensee is required by applicable law,  regulations or the
provisions  of any  material  contract  to which it is a party or by which it is
bound or at such other time as the  Proposed  SNH  Licensees  may elect in their
reasonable  discretion,  to  conduct  an  audit  of  the  Facilities'  financial
performance,  make available all books and records of the Facilities on a timely
basis and cooperate fully with any auditors or accountants  selected by Proposed
SNH  Licensee;  (c) as soon as  reasonably  possible  after  the  close  of each
applicable  reporting period for rate setting  purposes,  and not later than the
applicable  deadline,  prepare and submit a cost report for each  Facility  (and
including in any event,  any short-year  cost report required to be submitted by
the  Mariner  Licensee  or  Proposed  SNH  Licensee),   showing  the  costs  and
expenditures  relating  to  resident  care for  such  Facility  and  such  other
information as is required by the applicable governmental  authority,  each such
report being in all material respects  (including as to form) in compliance with
the requirements of such applicable  governmental  authority;  and (d) cooperate
with and furnish  information  to each  Proposed  SNH  Licensee and Manager in a
timely  manner  in  connection  with the  preparation  of  applications  by such
Proposed SNH Licensee for any Necessary Licenses with respect to the Facilities.

         3.5 Marketing.  The Mariner Licensees shall use commercially reasonable
efforts  to market the  services  of the  Facilities  in order to  maintain  the
patient  or  resident  census  at the  Facilities  in such  numbers  and of such
categories  as, in the Mariner  Licensees'  judgment,  will tend to maintain the
financial  stability of the Facilities and to ensure  compliance with applicable
laws,  regulations,  orders and  judgments  applicable  to the  Facilities.  The
Mariner  Licensees  may design and  implement  programs with third party payors,
such as insurance companies,  federal agencies and state and local agencies, for
services to  patients on a contract  basis,  for the  purpose of  improving  the
financial stability of the Facilities.

         3.6 Liaison  with  Agencies.  In  consultation  with the  Proposed  SNH
Licensees  and Manager,  the Mariner  Licensees  shall appear in,  prosecute and
defend all formal and informal  proceedings  before any and all local, state and
federal agencies which regulate the Facilities.  Each of the Mariner  Licensees,
the Proposed SNH Licensees and Manager shall  promptly  inform the others of the
commencement  of any such  proceedings  known to it  which  may have a  material
impact upon the operation of the  Facilities or which affect  reimbursement  for
services provided in or by the Facilities, including challenging any findings of
violations or the creation of a duty to correct.

         3.7  Insurance.   The  Mariner  Entities  shall  obtain  on  behalf  of
themselves, the Proposed SNH Licensees, the Manager and the Real Property Owners
for each Facility, as their interests may appear, all customary liability,  fire
and  extended  coverage,  professional  or  malpractice  liability  and worker's
compensation insurance covering the Facilities, any equipment used in connection
with the Facilities,  the Facilities'  employees,  and the Mariner Entities, the

                                      -5-


Proposed  SNH  Licensees,  the  Manager  and the Real  Property  Owners for each
Facility,  as  their  interests  may  appear,  in such  amounts  and  with  such
deductibles and other provisions as may be reasonably agreed upon by the Mariner
Entities, the Proposed SNH Licensees, the Manager and the Real Property Owners.

         3.8  Technical  and  Professional  Services.  The Mariner  Entities may
secure such engineering, legal, and other specialized technical and professional
services as may be necessary to advise or to represent the Mariner Entities, the
Proposed  SNH  Licensees,  the  Manager  and the Real  Property  Owners for each
Facility,  in  connection  with  any  matter  involving  or  arising  out of the
operation of the Facilities or the conduct of the Facilities.

         3.9  Necessary  Licenses.  Upon  receipt by the  relevant  Proposed SNH
Licensee or the Manager of the  Necessary  Licenses  with respect to a Facility,
the  Proposed  SNH  Licensee  or the  Manager  shall give the  relevant  Mariner
Licensee prompt written notice.

         3.10 Collections, Accounts, Disbursements and Termination Accounting.

                  (a) Billing.  The Mariner  Licensees  shall prepare and submit
bills for all moneys owing,  whether from  patients or third party  payors,  for
services  provided by or at the Facilities at any time,  whether prior to ______

Effective Time.

                  (b) Collection of Accounts  Receivable.  The Mariner Licensees
acknowledge  that,  from and after the  Effective  Time,  (i) the  Proposed  SNH
Licensees  shall,  to the extent  permitted by applicable  law, own all accounts

Mariner Licensees shall make and effect collections of all  Post-Effective  A/R,
(iii) the Mariner  Licensees  shall  establish  new bank  accounts (the "New A/R

all Third  Party  Payors and other  Persons  (as such  terms are  defined in the
Settlement  Agreement)  that  directly  deposit  monies into the  existing  bank
accounts (the "Existing A/R Accounts")  with respect to the Retained  Facilities
to terminate  such direct deposit and commence  depositing  such monies into the
New A/R  Accounts  from and  after the date  that is sixty  (60) days  after the
Effective  Time  (the  "Account  Transfer  Time")  or as soon as is  practicable
thereafter  (and the Mariner  Licensees shall take such further action as may be
reasonably  necessary  to cause such  Third  Party  Payors and other  Persons to

applicable  Proposed SNH  Licensee's  request  therefor  (but no sooner than the
applicable SNH Licensing Date), the Mariner Licensees shall assign, set over and
transfer  the New A/R  Accounts to the  Proposed  SNH  Licensees,  and (vii) the
Mariner Licensees shall disburse all proceeds attributable to Post-Effective A/R
deposited  in the  Existing  A/R

                                      -6-


Accounts or the New A/R  Accounts or  otherwise  received or held by the Mariner
Licensees to the Proposed SNH Licensees (or to such other Person as the Proposed
SNH Licensees may direct) within five (5) days of the Mariner Licensees' receipt
thereof.

         The SNH Entities and the Mariner  Licensees  acknowledge and agree that

or to other checking  accounts,  which books and records shall be made available
to the SNH Licensees and the Manager upon request, and after termination of this
Agreement  shall make such  books and  records  available  to the  Proposed  SNH
Licensees  and the Manager to the extent  necessary  to enable the  Proposed SNH
Licensee  and the Manager to comply with all  applicable  laws and  regulations,
including  regulations governing preparation and submission of cost reports. The
Mariner  Licensees  shall  timely  prepare  and  file  any  cost  reports  which
applicable laws and regulations  require that they file after the termination of
this Agreement.

         3.11 Patient  Trust  Accounts.  At such time as a Proposed SNH Licensee
has received all Necessary Licenses with respect to a Facility and has given the
Mariner  Licensee  notice as provided in Section 3.9, the Mariner  Licensee will
transfer the patient  trust  accounts  held for the benefit of residents of such
Facility  to the  Proposed  SNH  Licensee,  together  with  all  records  and an
accounting regarding such accounts.

4. Fee.  The  Mariner  Licensees  shall  earn,  for  services  rendered  by them
hereunder, a servicer fee (the "Fee") on a  Facility-by-Facility  basis for each
calendar  month  during  the term of this  Agreement  in an amount  equal to the
lesser of (i) five  percent (5%) of net patient  revenues (as defined  below) of
such Facility for such month and (ii) an amount  calculated by  multiplying  (A)
the sum of the Designated Services  Percentages,  as specified in the Designated
Services  Schedule,  attributable to the Designated  Services being performed by
the  applicable  Mariner  Licensee  at such  Facility  for such month by (B) the
amount of net patient revenues of such Facility for such month.

         Until  the  Agreed  Deficiency  shall  have been  reduced  to zero (0),
payment of the Fee shall be made by  dollar-for-dollar  reduction of the Reduced
Deficiency   (as  such   term  is   defined   in  the   Settlement   Agreement).
Notwithstanding anything to the contrary contained in this Section 4, in each of
the first  three (3) months of the term  hereof,  the Fee earned by the  Mariner
Licensees  hereunder  shall be not less than Four  Hundred  Thousand  ($400,000)
(regardless  of the amount of net patient  revenues at the  Facilities  for such
month or whether  the  Manager  shall have  elected to

                                      -7-


discontinue the Mariner  Licensees'  provision of any services  specified herein
during such period).

         As used in this Agreement,  "net patient  revenues" shall mean, for any
period,  the aggregate  amount of all revenues  (determined  in accordance  with
generally accepted accounting principals, consistently applied), received by, or
by reason of the operation of, such Facility  during such period,  but excluding
(a) revenues from  professional  fees or charges by physicians and  unaffiliated
providers of ancillary  services to the extent such charges are paid over to, or
separately   billed  by,  such  physicians  and  unaffiliated   providers,   (b)
non-operating  revenues, (c) revenues attributable to services provided off-site
to  non-patients,  and (d) all  revenues,  if any,  attributable  to child  care
services provided  primarily to employees of such Facilities,  but in all events
excluding any revenues  generated for services  provided to patients referred by
any Mariner Entity.

5. Expenses.

         5.1  During  the  period  from and after  the  Effective  Time to,  but
excluding,  the date of termination of this  Agreement,  for each Facility,  the
Mariner Licensee shall provide the Proposed SNH Licensees and the Manager with a

the  operation  and  management  of such  Facility  (the  "Expense  Statements")
accompanied by such  documentation  as the Proposed SNH Licensee and the Manager
shall reasonably request:

                  (a)  salary  and  expenses  (including,   without  limitation,
payroll taxes, workers'  compensation,  costs of employee benefit plans (or such
portion thereof as is properly allocable to such Facility),  travel,  insurance,
and  fidelity  bonds)  of  employees  at  such  Facility,   including,   without
limitation, administrative,  professional, custodial, food service, cleaning and
maintenance, operational, secretarial and bookkeeping personnel;

                  (b) all supplies and  equipment  necessary  and  desirable for
operation  of the such  Facility  as a skilled  nursing,  intermediate  care and
residential  facility;  food; fuel; kitchen and food service equipment;  linens;
beds; furniture; clothing and all other supplies and equipment used in supplying

insurance shall be allocated among the facilities  covered thereby on such basis
as the Mariner Licensees deem commercially appropriate based on their experience
in such matters and reasonable business judgment, including an assessment by the
Mariner Licensees of the differing risk profiles  associated with the facilities
and business of the Mariner  Licensees,  on the one hand, and the Facilities and
the business of the Proposed SNH Licensees, on the other)); and


                                      -8-


                  (d) all other costs,  expenses and liabilities  arising out of
the operation, maintenance and management of the Facilities,  including, without
limitation,  fees of  professionals  engaged to fulfill the  Mariner  Licensees'
obligations  under  Section 3.6 and Section  3.8,  but  excluding  those  costs,
expenses  and  liabilities  arising  out of any such  Mariner  Licensee's  gross
negligence or willful misconduct.

         5.2 The following  expenses of the Mariner  Licensees  shall be for the
sole account of the Mariner  Licensees and shall not be subject to reimbursement
hereunder: (a) overhead and ordinary administrative expenses, salary (including,
without  limitation,  payroll taxes,  workers'  compensation,  costs of employee
benefit plans,  travel,  insurance and fidelity bonds) of financial,  accounting
and other  personnel  employed by the Mariner  Licensees to provide  centralized
billing,  collection,  bill  paying,  accounting,  record  keeping,  information
management,  purchasing, personnel and policy planning services to any Facility,
it being understood that in no event shall the salary of the  administrator of a
Facility be an expense of the Mariner  Licensees;  and (b) any losses,  cost and
expenses under Section 11(a).

         5.3 The Proposed SNH  Licensees  shall cause the Manager to establish a
bank  account  under its name and control and to deposit and  maintain a minimum
balance therein of $100,000.  The Mariner Licensees shall have signing authority

the Manager  shall fund such account with an amount  sufficient  (over and above
the  minimum  balance) to fund and for the  purpose of paying the  expenses  set
forth in the Expense  Statement.  If any Mariner Licensee advances its own funds
for any approved  Expense  Statement  expense,  the Manager and the Proposed SNH
Licensees shall promptly reimburse such Mariner Licensee therefor.

         5.4 Each Proposed SNH Licensee of each Facility shall pay the Manager a
monthly management fee (the "Manager's Fee") for each Facility, payable prior to
the __ day following the end of each calendar month during the term hereof,  (i)
for the first two (2) months of the term hereof, in an amount equal to the costs
and expenses actually incurred by the Manager in connection with the performance
of its duties hereunder  during such calendar month, and (ii) thereafter,  in an
amount equal to 4.5% of net patient revenues for such Facility for such calendar
month.

6. Access to Records. For the time and to the extent required by applicable law,
including, without limitation, Section 1861(v)(1)(I) of the Social Security Act,
the Mariner Licensees shall retain, and shall permit the Comptroller  General of
the United States, the U.S.  Department of Health and Human Services,  and their
respective  duly   authorized   representatives,   and  duly  authorized   state
representatives,  access to  examine  or copy  this  Agreement  and such  books,
documents,  and  records as are  reasonably  necessary  to verify the nature and
extent of goods and  services  supplied  and the costs of the goods and services
supplied,  and the  payments  claimed  under  this  Agreement.  In the event any
Mariner Licensee provides any of its services under this Agreement pursuant to a
subcontract and if (i) the services  provided pursuant to the subcontract have a
value or cost of  $10,000 or more over a twelve  (12) month  period and (ii) the
subcontract is with a related  organization,  then such Mariner  Licensee agrees
that the  subcontract  shall  contain a clause  requiring the  subcontractor  to
retain  and allow  access to its  records on the same  terms and  conditions  as
required by such Mariner Licensee.

                                      -9-


7. Duty of Mariner  Licensees;  Prohibited  Transactions.  The Mariner Licensees

Fee, none of the Mariner  Licensees or any person,  firm or  corporation  which,
directly or indirectly owns or controls,  is owned or controlled by, or is under
direct or indirect common ownership or control with the Mariner Licensees or any
person  related by blood or marriage  within the third degree to persons in such
control  (an   "Affiliate"),   shall  receive  any   remuneration   (other  than
reimbursements and other payments expressly provided for herein), whether direct
or  indirect,  for any  purchases  of goods or  services  made on  behalf of the
Mariner  Licensees,  the Proposed SNH Licensees or the Manager,  and none of the
Mariner  Licensees or any of their Affiliates shall markup,  increase the price,
or obtain any premium for goods or services purchased by any Mariner Licensee on
behalf  of or for  the  benefit  of the  Mariner  Licensees,  the  Proposed  SNH
Licensees or the Manager.

8.  Relationship  of Parties.  No party to this  Agreement is a partner or joint
venturer  with any other party,  and nothing  herein shall be construed so as to
make  them  such  partners  or  joint  venturers  or  impose  on any of them any
liability as partners or joint venturers.

9. Term and Termination.

         9.1 The term of this Agreement shall commence at the Effective Time and
shall continue in full force for twelve (12) months unless earlier terminated as

         Subject to the  provisions of the first  paragraph in Section 1 of this

Facility(ies) which would be affected.

         9.2 From and after the effective  date of termination of this Agreement
in accordance  with Section 9.1, the Mariner  Licensees shall not be entitled to
compensation  for  further   services   hereunder  (and,  in  the  case  of  the
discontinuation  of services at a Facility in accordance  with Section 9.1, from
and after the effective date of such discontinuance, the Mariner Licensees shall
not be  entitled  to  compensation  for further  services  with  respect to such
Facility).  Upon termination or  discontinuance,  the relevant Mariner Licensees
shall forthwith:

                  (a)  pay  over  to the  relevant  Proposed  SNH  Licensee  all

                           INTERIM OCCUPANCY AGREEMENT

         This Interim Occupancy  Agreement (this "Interim Occupancy  Agreement")
is made this ___ day of 2000,  between [insert name of applicable New Operator],
a Delaware  corporation  ("Sublessor"),  and [insert name of applicable  Mariner
Licensee], a Delaware corporation ("Sublessee").

                                   WITNESSETH

         WHEREAS,  SPTMNR  Properties  Trust, a Maryland real estate  investment
trust  ("SPTMNR"),  and Sublessor are parties to an Amended and Restated  Master
Lease  Agreement,  dated as of  ____________  ___,  ______ (the  "Lease"),  with
respect to the skilled  nursing  facility  known as "[insert  name of facility]"
(the "Facility"); and

         WHEREAS,  SPTMNR,  Sublessor,  Sublessee and various other parties have
entered into a Settlement  Agreement (the "Settlement  Agreement"),  pursuant to
which  Sublessee has agreed to manage the operation of the Facility on the terms
contained therein and in an Interim Management  Agreement,  dated as of the date
hereof (the "Interim  Management  Agreement"),  between Sublessor and Sublessee;
and

         WHEREAS, in order to accomplish the foregoing,  Sublessor has agreed to
sublease the Facility to Sublessee on the terms contained herein;

         NOW THEREFORE, in consideration of the premises, and for other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged by the parties hereto,  the parties hereto,  intending to be bound,
hereby agree as follows:

         1. Sublease.  Upon and subject to the terms and conditions  hereinafter
set forth,  Sublessor  subleases to  Sublessee,  and  Sublessee  subleases  from
Sublessor,  all of  Sublessor's  right,  title and  interest  in,  to,  under or
relating  to the  real  property,  improvements,  fixtures  and  related  rights
constituting  the  Facility  (the  "Demised   Premises"),   including,   without
limitation,  any leasehold rights of Sublessor  relating to the use or occupancy
thereto,  and  Sublessor  agrees that  Sublessee  has and will  continue to have
throughout the term of this Interim  Occupancy  Agreement,  the right to use and
occupy the Demised Premises as the licensed operator of the Facility.

         2. Term. The term of this Interim Occupancy Agreement shall commence on
the  date  hereof,  and  shall  end on the  earlier  of (i) the  date  on  which
Sublessee's  obligation to provide services in connection with the management of
the operation of the Facility under the Interim Management  Agreement shall have
expired  or been  terminated  pursuant  to the  terms  thereof  and (ii) the SNH
Licensing Date (as defined in the Interim Management  Agreement).  Sublessor and
Sublessee acknowledge that under the Interim Management Agreement, Sublessor may
terminate Sublessee's provision of one or more services thereunder,  and that if
Sublessor shall elect to do so, this Interim Occupancy Agreement shall remain in
effect  notwithstanding  such termination  until Sublessor shall have elected to
terminate  Sublessee's  provision of all services  under the Interim  Management
Agreement with respect to the Facility.


         3.  Rent.  Sublessee  shall pay to  Sublessor  as the rent  under  this
Interim Occupancy Agreement (the "Rent"),  all net patient revenues derived from
the  operation  of the  Facility  during  the  term  of this  Interim  Occupancy
Agreement  to the extent such net patient  revenues  are  actually  collected by
Sublessee.  Except as expressly set forth in the preceding  sentence,  Sublessee
shall  have no  obligation  to pay any  amounts or perform  any  obligations  in
respect of this Interim Occupancy Agreement;  it being the purpose and intent of
Sublessor and Sublessee that this Interim  Occupancy  Agreement is a gross lease
and  that  except  for  the  payment  of  the  Rent,  all  costs,  fees,  taxes,
impositions,  utility  charges,  repairs,  alterations,  restorations,  charges,
expenses,  reimbursements  and  obligations of every kind and manner  whatsoever
relating to the Demised  Premises  which may arise or become due during or after
the term of this Interim  Occupancy  Agreement,  shall be paid and discharged by
Sublessor.

         4.  Surrender  of  Possession.  At the end of the term of this  Interim
Occupancy Agreement, Sublessee shall surrender the Facility to Sublessor and, if
Sublessee shall fail to do so, Sublessee shall be a tenant-at-sufferance subject
to all of the terms of this Interim  Occupancy  Agreement except that Rent shall
be twice the Rent in effect  immediately  prior to the expiration or termination
hereof.  Sublessee  shall be liable for all damages  incurred by  Sublessor as a
result of such holding over.

         5. No Subletting or  Assignment.  Sublessee  shall not sublet or assign
any or all of the Facility  without the prior  consent of  Sublessor;  provided,
however,  that the  foregoing  shall not be deemed to  prohibit  Sublessee  from
permitting  patients or residents to occupy the Facility in the ordinary  course
of Sublessee's business.

         6. Notices.  All notices  required or permitted  hereunder  shall be in
writing and shall be deemed to be properly  given when  personally  delivered to
the party  entitled to receive the notice or on the date of actual  receipt,  if
sent by  certified  or  registered  mail,  postage  prepaid  and return  receipt
requested,  or one  business  day  after  being  sent by  nationally  recognized
