                  (a) PAYMENT FOR SERVICES. RMR shall be paid a fee for the
         Services provided to the Company under this Agreement (the "Service
         Fee") equal to 0.6% of total revenues ("Revenues") of the Company from
         all sources reportable under generally accepted accounting principles
         ("GAAP"). The Service Fee shall be estimated and paid monthly by the
         Company in advance based upon the prior calendar month's Revenues, and
         such payment shall be paid within 15 calendar days of the end of the
         applicable prior calendar month. The calculation of the fee for any
         month shall be based upon the Company's monthly financial statements
         and shall be in reasonable detail. A copy of the computations shall
         promptly be delivered to RMR accompanied by payment of the Service Fee
         thereon to be due and payable. The Services Fee shall be pro-rated for
         any partial month this Agreement shall be in effect.

                  The aggregate Service Fee paid in any fiscal year shall be
         subject to adjustment as of the end of that year. On or before the 30th
         day after public availability of the Company"s annual audited financial
         statements for each fiscal year, the Company shall deliver to RMR a
         notice setting forth (i) the Company's Revenues for such year, (ii) the
         Company"s computation of the Service Fee payable for such year and
         (iii) the amount of the Service Fee theretofore paid to RMR in respect
         of such year. If the Service Fee


                                      -4-


         payable for any fiscal year exceeds the aggregate amounts previously
         paid by the Company, the Company shall pay the deficit to RMR at the
         time of delivery of such notice. If the aggregate Service Fee payable
         for any fiscal year as shown in the notice is less than the aggregate
         amounts previously paid by the Company, the Company shall specify in
         such notice whether RMR should (i) refund to the Company an amount
         equal to the difference or (ii) grant the Company a credit against the
         Service Fee next coming due in the amount of the difference until that
         amount has been fully paid or otherwise discharged.

                  (b) PAYMENT SUBORDINATION. No Service Fee payments shall be
         paid by the Company to RMR if any of the contractual rent obligations
         of the Company or any of its subsidiaries to Senior Housing Properties
         Trust or any of its subsidiaries (collectively "Senior Housing")
         pursuant to any lease agreement are in arrears or if such Service Fee
         payment would leave the Company with insufficient cash, credit
         facilities or current accounts receivable to make its next scheduled
         rent payment to Senior Housing pursuant to any lease agreement. Any
         Service Fee payment unpaid as a result of the preceding sentence shall
         accrue interest until paid at the Prime Rate (as defined below), and
         shall be automatically due and payable: (i) as and to the extent cash,
         credit facilities or current accounts receivable are available after
         payment of, or provision for, rent, (ii) upon any termination of the
         Agreement, or (iii) upon the occurrence of any event of default by the
         Company enumerated in subparagraph 3.2. This subparagraph 1.3(b) is
         only intended to define the relative rights of RMR and Senior Housing.
         Without intending to limit the generality of the foregoing, nothing in
         this subparagraph 1.3(b) shall: (i) impair, as between the Company and
         RMR, the obligation of the Company to pay any amounts owing hereunder
         in accordance with the terms hereof; or (ii) affect the relative rights
         of RMR and creditors of the Company other than Senior Housing. For
         purposes of this Agreement, "Prime Rate" shall mean the Prime Rate or
         base rate on corporate loans at large U.S. money center commercial
         banks as published in the WALL STREET JOURNAL or, if publication of
         such rate shall be suspended or terminated, Prime Rate shall mean the
         annual rate of interest, determined daily and expressed as a
         percentage, from time to time announced by one of the three largest
         national or New York State chartered banking institutions having their
         principal office in New York, New York and selected by RMR at the time
         such publication is suspended or terminated. All interest hereunder
         shall be calculated on the basis of actual days elapsed and a 360-day
         year.

                 1.4 REIMBURSEMENT. The Company shall reimburse RMR for
reasonable out-of-pocket expenses of RMR employees incurred in their performance
of the Services (the "Expenses") and for reasonable third party expenses RMR
incurs on behalf of the Company that are not billed directly to the Company, in
each case within 30 days of receipt of the invoice therefor, but only to the
extent, as to such third party expenses and costs, the Company shall have
approved such expenses and costs. RMR shall submit to the Company such reports
detailing said expenses and supporting receipts and bills, or other suitable
evidence, as may be, reasonably requested by the Company.

inadequate. Upon any such breach, the relevant Benefited Party shall be entitled
(in addition to any other rights or remedies it may have at law) to seek an
injunction enjoining and restraining the Company or such subsidiaries from
continuing such breach. The Company agrees that the period of restriction and
the geographical area of restriction imposed upon the Company are fair and
reasonable. If the provisions of this subparagraph 6.1 relating to the period or
the area of restriction are determined to exceed the maximum period or areas
which a court having jurisdiction over the matter would deem enforceable, such
period or area shall, for purposes of this Agreement, be deemed to be the
maximum period or area which such court determines valid and enforceable.

                 6.2 ADDITIONAL COVENANTS. In the event RMR shall enter into an
advisory arrangement or agreement with any other publicly owned entity, other
than the Benefited Parties, RMR shall provide the Company with notice thereof.
The notice shall specify in reasonable detail the identity of the entity, the
types of properties owned or financed by such additional entity, and such entity
shall be deemed and become a "Benefited Party" for all purposes of this
Agreement.

         Section 7. RMR RESTRICTIONS. Other than activities or arrangements
existing as of the date hereof or those consented to by the Company, RMR shall
not directly or indirectly provide any advice or assistance to any business or
enterprise that is competitive with the Company's business, including, but not
limited to, any business or enterprise that manages or operates senior
apartments, congregate communities, assisted living properties, nursing homes or
other healthcare properties.

         Section 8. INDEMNIFICATION; REMEDIES.

                 8.1 BY THE COMPANY. The Company shall indemnify, defend and
hold RMR, and its directors, officers, employees and agents harmless from and
against any and all damages, claims, losses, expenses, costs, obligations and
liabilities, including, without limiting the generality of the foregoing,
liabilities for all reasonable attorneys', accountants' and experts' fees and
expenses incurred (collectively, "Losses and Expenses") or suffered by them by
reason of or arising out of the course of performing the Services and any duties
on behalf of the Company and its subsidiaries as prescribed hereby, except for
matters covered by subparagraph 8.2 hereof.

                 8.2 BY RMR. RMR shall indemnify, defend and hold the Company
and its subsidiaries and their respective directors, trustees, officers,
employees and agents harmless from and against Losses and Expenses suffered by
them by reason of or arising out of any willful bad faith or gross negligence in
the performance of any obligation or agreement of RMR herein.

                 8.3 COMPANY REMEDIES. Except as otherwise provided in
subparagraph 8.2 hereof, RMR does not assume any responsibility under this
Agreement other than to render the Services called for under this Agreement in
good faith. Except as otherwise provided in subparagraph 8.2 hereof, the
Company's remedy on account of the failure of RMR to render the Services as and
when required hereunder shall be to terminate this Agreement; provided however,
that if RMR acts with willful bad faith or gross negligence, the Company's
remedy shall be to procure services elsewhere and to charge RMR the difference
between the reasonable increased cost, if any, to procure new services, and the
Service Fee, pro-rated, that would have been payable to RMR had RMR performed
such Services under this Agreement.

                 8.4 RMR REMEDIES. Except as otherwise provided in subparagraph
8.1, the Company does not assume any responsibility under this Agreement other
than to pay the Services Fee in accordance with the terms of this Agreement.
Except as otherwise provided in subparagraph 8.1, RMR's sole remedy on account
of the failure of the Company to pay the Service Fee as and when required under
this Agreement shall be to terminate this Agreement and receive the Service Fee
payable for the then remaining Initial Term or Renewal Term of this Agreement,
as the case may be.

         Section 9. SELF-DEALING. Neither RMR nor any Affiliate of RMR shall,
directly or indirectly, sell any property or assets to the Company or purchase
any property or assets from the Company, lease any property from the Company or
borrow any money from the Company, except as approved by the Company. In
addition, except as otherwise provided in Section 1 hereof, neither RMR nor any
Affiliate of RMR shall receive any commission or other remuneration, directly or
indirectly, in connection with the activities of the Company or any joint
venture or partnership in which the Company is a party. The foregoing
prohibitions shall not apply to (i) the lease of office space by the Company
from an Affiliate of RMR, (ii) the Company's acquisition of FSQ, Inc., or (iii)
FSQ, Inc.'s provision of management services to or on behalf of the Company.

         As used in this Agreement, the term "Affiliate" means, as to RMR, (i)
any other Person (as defined below) directly or indirectly controlling,
controlled by or under common control with RMR, (ii) any other Person that owns
beneficially, directly or indirectly, five percent (5%) or more of the
outstanding capital stock, shares or equity interests of RMR, or (iii) any
officer, director, trustee, employee or general partner of RMR or of any Person
controlling, controlled by


                                      -9-


or under common control with RMR. The term "Person" means and includes
individuals, corporations, limited partnerships, general partnerships, limited
liability companies, joint stock companies or associations, joint ventures,
associations, companies, trusts, banks, trust companies, land trusts, business
trusts and other entities.

         Section 10. RELATIONSHIP OF THE PARTIES.

                 10.1 NO PARTNERSHIP OR JOINT VENTURE. The parties are not
partners or joint venturers with each other and neither the terms of this
Agreement nor the fact that the Company and RMR have joint interests in any one
or more investments, have common employees or have a tenancy relationship shall
be construed so as to make them partners or joint venturers or impose any
liability on either of them.

                 10.2 CONFLICTS OF INTEREST. The parties acknowledge that, as of
the date hereof, (i) the Company is a tenant of an Affiliate of RMR pursuant to
a lease agreement relating to office space, (ii) the Company and its
subsidiaries lease all or substantially all of their real estate from Senior
Housing and may enter into additional leases or other transactions with Senior
Housing, and (iii) RMR is the investment advisor to Senior Housing pursuant to
an advisory agreement. The parties agree that these relationships shall not
affect either party's rights and obligations under this Agreement; PROVIDED,
HOWEVER, the Company acknowledges and agrees that whenever any conflicts of
interest arise resulting from the relationships described in this subparagraph
10.2 or any such relationship as may arise or be present in the future by and
between the Company and any of RMR, Affiliates of RMR or any publicly owned
entity with whom RMR has a relationship or contract: (i) RMR will act on its own
behalf and on behalf of Senior Housing or such entity and not on the Company's
behalf, and (ii) the Company shall make its own decisions and require and obtain
the advice and assistance of independent third parties at its own cost, as it
may deem necessary.

         Section 11. RECORDS. RMR shall maintain appropriate books and records
relating to Services performed pursuant to this Agreement, which books and
records shall be available for inspection by representatives of the Company upon
reasonable notice during ordinary business hours.

         Section 12. ASSIGNMENT. The Company may terminate this Agreement in the
event of its assignment by RMR except in the case of an assignment to a
corporation, partnership, trust, or other successor entity which may take over
the property and carry on the affairs of RMR; provided that, following such a
permitted assignment, one or more of the persons who controlled the operations
of RMR immediately prior to the assignment shall control the operations of the
successor, including the performance of its duties under this Agreement, and
this successor shall be bound by the same restrictions by which RMR was bound
prior to such assignment. A permitted assignment or any other assignment of this
Agreement by RMR shall bind the assignee hereunder in the same manner as RMR is
bound hereunder. This Agreement shall not be assignable by the Company without
the prior written consent of RMR, except in the case of any assignment by the
Company to a trust, corporation, partnership or other entity which is the
successor to the Company so long as there is no Change in Control, in which case
the successor shall be bound hereby and by the terms of said assignment in the
same manner and to the same extent as the Company is bound hereby. For purposes
of this Agreement, a "Change in Control"


                                      -10-


shall mean (a) the acquisition by any person or entity (each a "Person"), or two
or more Persons acting in concert, of beneficial ownership (within the meaning
of Rule 13d-3 of the SEC) of 9.8% or more, or rights, options or warrants to
acquire 9.8% or more, of the outstanding shares of voting stock of the Company,
(b) any one or more sales or conveyances to any Person of all or any material
portion of the assets (including capital stock) or business of the Company, or
(c) the cessation, for any reason, of the individuals who at the beginning of
any twenty-four (24) consecutive month period commencing on the date hereof, or
any anniversary thereof, constitute the Board of Directors of the Company
(together with any new directors whose election by such Board or whose
nomination for election by the shareholders of the Company, was approved by a
vote of a majority of the directors then still in office who were either
directors at the beginning of any such period or whose election or nomination
for election was previously so approved) to constitute a majority of the Board
of Directors of the Company then in office.

         Section 13. ARBITRATION. The Company and RMR agree that any and all
disputes and disagreements arising out of or relating to this Agreement, other
than actions or claims for injunctive relief or claims raised in actions or
proceedings brought by third parties, shall be resolved through negotiations or,
if the dispute is not so resolved, through binding arbitration conducted in
Boston, Massachusetts under the J.A.M.S./Endispute Comprehensive Arbitration
Rules and Procedures, with the following amendments to those rules. First, the
parties agree that in no event shall the arbitration from commencement to
issuance of an award take longer than 180 days. Second, the parties agree that
the arbitration tribunal shall consist of three arbitrators and that the parties
elect not to have the optional appeal procedure provided for in Rule 23. Third,
in lieu of the depositions permitted in Rule 15(E) and (F), the parties agree
that the only depositions shall be a single deposition to last no longer than
one six-hour day that each party may take of the opposing party or an individual
under the control of the opposing party. Judgment on the award rendered by the
arbitrators may be entered in any court having jurisdiction thereof.

         Section 14. NOTICES.

                  (a) Any and all notices, demands, consents, approvals, offers,
         elections and other communications required or permitted under this
         Agreement shall be deemed adequately given if in writing and the same

         similar expedited commercial carrier, addressed to the recipient of the
         notice, postpaid and registered or certified with return receipt
         requested (if by mail), or with all freight charges prepaid (if by

         Agreement a notice is either received on a day which is not a business
         day or is required to be delivered on or before a specific day which is
         not a business day, the day of receipt or required delivery shall
         automatically be extended to the next business day.
