                                      -5-
<PAGE>



     4.1. ORGANIZATION, ETC.

     FSQ is duly organized, validly existing and in good standing as a
corporation under the laws of the state of Delaware and has all requisite power
and authority (i) to conduct its business as it is now conducted, (ii) to own or
lease all of the properties owned or leased by it, (iii) to enter into and
perform this Agreement and (iv) to otherwise consummate the transactions
contemplated by this Agreement. The records and minute books of FSQ contain
complete and accurate, in all material respects, minutes of all meetings of the
directors and the shareholders of FSQ since the date of its formation, all such
meetings were duly called and held, and the stock record books and register of
holders of common stock of FSQ are complete and accurate. FSQ is duly qualified
to do business and is in good standing in all jurisdictions in which the
ownership or lease of property by it or the conduct of its business makes such
qualification necessary, except where the failure to be qualified does not have
and would not be reasonably expected to have a Material Adverse Effect on FSQ.

     4.2. AUTHORIZATION; EXECUTION; BINDING EFFECT.

     The execution and delivery of this Agreement, and the consummation of the
transactions provided for in this Agreement, have been duly authorized by all
necessary corporate and stockholder action on the part of FSQ and this Agreement
constitutes the legal, valid and binding obligation of FSQ, enforceable against
it in accordance with its terms, except as enforceability may be limited by
bankruptcy, insolvency, reorganization, or other laws affecting creditors'
rights and remedies generally and by general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law).

     4.3. CAPITALIZATION.

     The authorized capital stock of FSQ consists of 3,000 shares of common
stock $0.01 par value, of which 1,000 shares are issued and outstanding. FSQ has
not issued any options or any securities convertible into common stock of FSQ.
All of such outstanding common stock of FSQ has been duly authorized and validly
issued, is fully paid and nonassessable and is not subject to any preemptive or
similar rights. FSQ is not a party to or bound by any agreement, put or
commitment pursuant to which it is obligated to purchase, redeem or otherwise
acquire any of its common stock or any options or securities convertible into
its common stock.

     4.4. SUBSIDIARIES.

     FSQ does not have any Subsidiaries or own, directly or indirectly, or
control any equity or voting interest in any Person, except for Advertising.

     Advertising is duly organized, validly existing and in good standing as a
corporation under the laws of the state of Delaware. Advertising has not engaged
in any business, and has not incurred any liabilities of any nature whatsoever,
except for franchise taxes and like expenses required to be incurred by it to
maintain its existence or qualification. The authorized capital stock of
Advertising consists of 3,000 shares of common stock $0.01 par value, of which
1,000 shares are issued and outstanding. All of such outstanding common stock of
Advertising has been duly authorized and validly issued, is fully paid and
nonassessable and is not subject to any preemptive or similar rights. All of the
issued and outstanding common stock of Advertising is


                                      -6-
<PAGE>



owned beneficially and of record by FSQ, free and clear of all Liens. There are
no outstanding options, rights or agreements of any kind relating to the
issuance, sale or transfer of any capital stock of Advertising.

     4.5. NO CONFLICTING AGREEMENTS OR CHARTER PROVISIONS.

     The execution, delivery and compliance with and performance of the terms
and provisions of this Agreement will not conflict with or result in a breach of
the terms, conditions or provisions of, or constitute a default under, or result
in any violation of, (i) the Charter or Bylaws of FSQ or Advertising or any
resolutions adopted by their respective directors or stockholders, (ii) any
provision of any material Contract to which FSQ or Advertising is a party or by
which they or any part of their respective assets may be bound, or (iii) any
order, judgment, decree, license, permit, statute, law, rule or regulation to
which FSQ or Advertising is subject. The execution, delivery and performance of
this Agreement will not result in the creation of any Lien upon or any
preferential arrangement with respect to the business or any part of the assets
or properties of FSQ or Advertising.

     4.6. LITIGATION.

     There is (whether insured or uninsured) no action, suit, proceeding or
investigation pending or, to the knowledge of FSQ, threatened, at law or in
equity, in any court or before or by any federal, state, municipal or other
governmental authority, department, commission, board, agency or other
instrumentality (i) against FSQ or Advertising or, to the knowledge of FSQ,
affecting FSQ or Advertising, except for private civil litigation involving
claims which will not have a Material Adverse Effect on FSQ, (ii) to the
knowledge of FSQ, against or adversely affecting any officer or director of FSQ
or Advertising, or (iii) adversely affecting this Agreement or any action taken
or to be taken or documents executed or to be executed pursuant to or in

(financial or otherwise), assets, liabilities, personnel, and policies contained
herein, in any Schedule (as the same are superseded or supplemented prior to the

                            INDEMNIFICATION AGREEMENT
                                (see attachment)



<PAGE>

                            INDEMNIFICATION AGREEMENT

     THIS INDEMNIFICATION AGREEMENT ("AGREEMENT") is made and entered into
___________, 2001, by and among the undersigned stockholders (the
"STOCKHOLDERS") of FSQ, Inc., a Delaware corporation ("FSQ"), and FIVE STAR
QUALITY CARE, INC., a Maryland corporation ("FIVE STAR").

                                    RECITALS


     A. Five Star, FSQ Acquisition, Inc., a Delaware corporation ("MERGER SUB")
and FSQ have entered into an Agreement of Merger, dated December 5, 2001 (the
"MERGER AGREEMENT"), pursuant to which Merger Sub will be merged with and into
FSQ, with FSQ remaining as the survivor (the "MERGER").

     B. Pursuant to the Merger Agreement, each share of common stock of FSQ
outstanding immediately prior to the Merger will be converted into a right to
receive 250 shares of common stock, par value $0.01, of Five Star (the "FIVE
STAR COMMON SHARES").

     C. On the date hereof, each Stockholder owns 50% of the issued and
outstanding shares of common stock of FSQ.

     D. Pursuant to the terms of the Merger Agreement, and as a condition to
Five Star's obligations under the Merger Agreement, the Stockholders have agreed
to provide certain indemnities to Five Star and the other Indemnified Parties
(as hereinafter defined).

     NOW, THEREFORE, the parties agree as follows:

     1. DEFINITIONS. Capitalized terms used but not otherwise defined in this
Agreement shall have the meanings given therefor in the Merger Agreement.

     2. INDEMNIFICATION BY THE STOCKHOLDERS.

     Subject to the other provisions of this Agreement, for the period from and
after the Closing and ending January 1, 2003 (the "CLAIM PERIOD"), each of the
Stockholders shall indemnify and hold harmless, Five Star and its subsidiaries
and affiliates, each of their respective officers, trustees, directors,
employees, agents and representatives, and each of the heirs, executors,
successors and assigns of any of the foregoing (collectively, the "INDEMNIFIED
PARTIES"), against such Stockholder's Allocable Portion (as defined in PARAGRAPH
4 below) of any losses, claims, damages, liabilities or expenses whenever
arising or incurred (including, without limitation, amounts paid in settlement,
reasonable costs of investigation and reasonable attorneys' fees and expenses)
(collectively, "LOSSES") arising out of or relating to any breach of any
representation or warranty made by FSQ in the Merger Agreement, provided that,
solely for the purposes of this Agreement no breach shall be deemed to have
occurred if the applicable representation and warranty made by FSQ (other than
the representations and warranties made by FSQ in Sections 4.1 though 4.4, 4.5
(as to clauses (i) and (ii) of the first sentence thereof and


<PAGE>


the second sentence thereof), 4.6 (except to the extent such representation is
qualified as to knowledge), 4.9 (except to the extent such representation is
qualified as to knowledge), 4.11, 4.16 and 4.20 of the Merger Agreement) would
have been true and correct in all material respects had it been qualified by the
phrase "to the knowledge of FSQ" (as defined in the Merger Agreement), whether
or not so qualified in the Merger Agreement.

     3. INDEMNIFICATION PROCEDURE.

           (a) Promptly after receipt by an Indemnified Party of notice of
     the commencement of any action or proceeding involving a claim to which
     indemnification is being sought, such Indemnified Party will, if a claim
     is to be made against any Stockholder, give notice to each stockholder
     of the commencement of such action or proceeding.

           (b) In case any such action is brought against an Indemnified
     Party, unless in such Indemnified Party's reasonable judgment a conflict
     of interest between the Indemnified Party and either Stockholder may
     exist in respect of such claim, the Stockholders shall be entitled to
     assume and control the defense of such action to the extent that they
     may wish, with counsel reasonably satisfactory to such Indemnified
     Party, and after notice from the Stockholders to such Indemnified Party
     of their election so to assume and control the defense of such action,
     the Stockholders shall not be liable to such Indemnified Party for any
     legal or other expenses subsequently incurred by the latter in
     connection with the defense of such action other than reasonable costs
     of investigation. Notwithstanding the foregoing, in any such action, any
     Indemnified Party shall have the right to retain its own counsel, but
     the fees and disbursements of such counsel shall be at the expense of
     such Indemnified Party unless the Stockholders shall have failed to
     retain counsel for the Indemnified Party. It is understood that the
     Stockholders shall not, in connection with any action or related actions
     in the same jurisdiction, be liable for the fees and disbursements of
     more than one separate firm qualified in such jurisdiction to act as
     counsel for all Indemnified Parties, unless in any such Indemnified
     Party's reasonable judgment a conflict of interest between such
     Indemnified Party and any other indemnified party may exist in respect
     of such claim. the Stockholders shall not be liable for any settlement
     of any proceeding effected without their consent; no Stockholder shall,
     without the consent of the Indemnified Party, consent to entry of any
     judgment or enter into any settlement which does not include as an
     unconditional term the giving by the claimant or plaintiff to such
     Indemnified Party of a release from all liability in respect to such
     claim or litigation.

     4. LIABILITY LIMITS; ALLOCABLE PORTION; ETC.

           (a) The Stockholders shall have no liability for losses until such
     time as the aggregate of such Losses exceeds $50,000 (the "DEDUCTIBLE"),
     and thereafter each Stockholder shall indemnify the Indemnified Parties
     for such Stockholder's Allocable Portion of all Losses incurred in
     excess of the Deductible.

           (b) Each Stockholder's aggregate liability for all Losses under
     this Agreement shall not exceed the value of the Merger Consideration
     paid to such Stockholder,

                                      -2-


<PAGE>


     determined as of the Closing Date. The value of each Five Star Common
     Share paid as Merger Consideration shall be deemed to equal the closing
     sale price for a Five Star Common Share as reported by the American
     Stock Exchange for the Closing Date.

           (c) In satisfaction of any liability hereunder, each Stockholder
     shall tender to the Indemnified Party such number of Five Star Common
     Shares as is sufficient to satisfy his Allocable Portion of such
     liability. Each Five Star Common Share delivered in satisfaction of a
     claim made under PARAGRAPH 2 or 3 above shall be valued at the closing
     sale price for a Five Star Common Share as reported by the American
     Stock Exchange for the Closing Date.

           (d) A Stockholder's "Allocable Portion" of any Losses or claims
