Ladies and Gentlemen:

     Five Star Quality Care, Inc., a Maryland corporation (the "Company"),
proposes to issue and sell to the underwriters named in Schedule A annexed
hereto (the "Underwriters") an aggregate of 3,000,000 shares of Common Stock,
$0.01 par value per share (the "Common Stock"), of the Company (the "Firm
Shares"). In addition, solely for the purpose of covering over-allotments, the
Company proposes to grant to the Underwriters the option to purchase from the
Company up to an additional 450,000 shares of Common Stock (the "Additional
Shares"). The Firm Shares and the Additional Shares are hereinafter collectively
sometimes referred to as the "Shares." The Shares are described in the
Prospectus which is referred to below.

     The Company has filed, in accordance with the provisions of the Securities
Act of 1933, as amended, and the rules and regulations thereunder (collectively,
the "Act"), with the Securities and Exchange Commission (the "Commission") a
registration statement on Form S-1 (File No. 333-119955) including a prospectus,
relating to the Shares. The Company has furnished to you, for use by the
Underwriters and by dealers, copies of one or more preliminary prospectuses
(each thereof being herein called a "Preliminary Prospectus") relating to the
Shares. Except where the context otherwise requires, the registration statement,
as amended when it becomes effective, including all documents filed as a part
thereof, and including any information contained in a prospectus subsequently
filed with the Commission pursuant to Rule 424(b) under the Act and deemed to be
part of the registration statement at the time of effectiveness pursuant to Rule
430(A) under the Act, and also including any registration statement filed
pursuant to Rule 462(b) under the Act, is herein called the "Registration
Statement," and the prospectus, in the form filed by the Company with the
Commission pursuant to Rule 424(b) under the Act on or before the second
business day after the date hereof (or such earlier time as may be required
under the Act) or, if no such filing is required, the form of final prospectus
included in the Registration Statement at the time it became effective, is
herein called the "Prospectus." Any reference herein to the Registration
Statement, a Preliminary Prospectus or the Prospectus shall be deemed to refer
to and include the copy of the Registration Statement, Preliminary Prospectus or
Prospectus filed with the Commission pursuant to its Electronic Data Gathering,
Analysis and Retrieval system ("EDGAR").

                                       1

     The Company and the Underwriters agree as follows:

     1. SALE AND PURCHASE. On the basis of the representations and warranties
herein and subject to the terms and conditions herein set forth, the Company
agrees to issue and sell to each Underwriter and, upon the basis of the
representations, warranties and agreements of the Company herein contained and
subject to all the terms and conditions set forth herein, each Underwriter
agrees, severally and not jointly, to purchase from the Company, at a purchase
price of $_____ per Share (the "purchase price per share"), the number of Firm
Shares set forth opposite the name of such Underwriter in Schedule A annexed
hereto (or such number of Firm Shares increased as set forth in Section 8
hereof).

     The Company is advised by you that the Underwriters intend (i) to make a
public offering of their respective portions of the Firm Shares as soon after
the effective date of the Registration Statement as in your judgment is
advisable and (ii) initially to offer the Firm Shares upon the terms set forth
in the Prospectus. You may from time to time increase or decrease the public
offering price after the initial public offering to such extent as you may
determine.

     In addition, the Company hereby grants to the several Underwriters the
option to purchase, and upon the basis of the representations, warranties and
agreements of the Company and subject to the terms and conditions herein set
forth, the Underwriters shall have the right to purchase, severally and not
jointly, from the Company all or a portion of the Additional Shares as may be
necessary to cover over-allotments made in connection with the offering of the
Firm Shares, at the same purchase price per share to be paid by the Underwriters
to the Company for the Firm Shares. This option may be exercised by you on
behalf of the several Underwriters at any time on or before the 30th day
following the date hereof by written notice to the Company. Such notice shall
set forth the aggregate number of Additional Shares as to which the option is
being exercised and the date and time when the Additional Shares are to be
delivered (such date and time being herein referred to as the "additional time
of purchase"); PROVIDED, HOWEVER, that the additional time of purchase shall not
be earlier than the time of purchase (as defined below) nor earlier than the
second business day1 after the date on which the option shall have been
exercised nor later than the tenth business day after the date on which the
option shall have been exercised. The number of Additional Shares to be sold to
each Underwriter shall be the number which bears the same proportion to the
aggregate number of Additional Shares being purchased as the number of Firm
Shares set forth opposite the name of such Underwriter on Schedule A hereto
bears to the total number of Firm Shares (subject, in each case, to such
adjustment as you may determine solely to eliminate fractional shares).

     2. PAYMENT AND DELIVERY. Payment of the purchase price for the Firm Shares
shall be made to the Company by Federal Funds wire transfer, against delivery of
the certificates for the Firm Shares to you through the facilities of the
Depository Trust Company ("DTC") for the respective accounts of the
Underwriters. Such payment and delivery shall be made at 10:00 A.M., New York

     ensure that material information relating to the Company, including its
     consolidated Subsidiaries, is made known to the Company's Chief Executive
     Officer and its Chief Financial Officer by others within those entities,
     and such disclosure controls and procedures are effective to perform the
     functions for which they were established; the Company's auditors and the
     Audit Committee of the Board of Directors have been advised by the
     Company's Chief Executive Officer and Chief Financial Officer of (i) any
     significant deficiencies in the design or operation of the Company's
     internal control over financial reporting which are reasonably likely to
     adversely affect the Company's ability to record, process, summarize, and

                                       10

     the Company's internal control over financial reporting; any material
     weaknesses in the Company's internal control over financial reporting have
     been identified for the Company's auditors; and since the date of the most
     recent evaluation of such disclosure controls and procedures, there has

     to materially affect, the Company's internal control over financial
     reporting;

          (ff) the Company has provided you true, correct, and complete copies

     of any director or executive officer of the Company; and since July 30,
     2002, the Company has not, directly or indirectly, including through any
     Subsidiary (i) extended credit, arranged to extend credit, or renewed any
     extension of credit, in the form of a personal loan, to or for any director
     or executive officer of the Company, or to or for any family member or
     affiliate of any director or executive officer of the Company or (ii) made
     any material modification, including any renewal thereof, to any term of
     any personal loan to any director or executive officer of the Company, or
     any family member or affiliate of any director or executive officer, which
     loan was outstanding on July 30, 2002;

          (gg) the Company has taken all necessary actions to ensure that, upon
     and at all times after the effectiveness of the Registration Statement, the
     Company and the Subsidiaries and, to the Company's knowledge, any of the
     officers and directors of the Company and any of the Subsidiaries, in their
     capacities as such, will be in compliance in all material respects with the
     applicable provisions of the Sarbanes-Oxley Act of 2002 and the rules and
     regulations promulgated thereunder;

          (hh) the Company and the Subsidiaries have filed all federal, state,

     all taxes shown by such returns or otherwise assessed that are due or
     payable have been paid, except such taxes as are being contested in good
     faith and as to which adequate reserves have been provided; all payroll
     withholdings required to be made by the Company and the Subsidiaries with
     respect to employees have been made except where the failure to fulfill or
     perform, would not, individually or in the aggregate, have a Material
     Adverse Effect; the charges, accruals and reserves on the books of the
     Company and the Subsidiaries in respect of any tax liability for any year
     not finally determined are adequate to meet any assessments or
     reassessments for additional taxes; there have been no tax deficiencies
     asserted and, to the Company's knowledge, no tax deficiency might be
     reasonably asserted or threatened against the Company and/or the
     Subsidiaries that would, individually or in the aggregate, have a Material
     Adverse Effect;

          (ii) the outstanding Common Stock is, and the Shares will be, subject

     Exchange (the "AMEX"); and

     Material Adverse Effect, the Company and the Subsidiaries own, possess,
     license or have other rights to use, all patents, trademarks, servicemarks,
     trade names, copyrights, trade secrets, information, proprietary rights and
     processes necessary for their business as described in the Registration
     Statement and the Prospectus.

In addition, any certificate signed by any officer of the Company and delivered
to the Underwriters or counsel for the Underwriters in connection with the
offering of the Shares shall be deemed to be a representation and warranty by
the Company, as to matters covered thereby, to each Underwriter.

          express no opinion) comply as to form in all material respects with
          the requirements of the Act;

               (iv) the Registration Statement has become effective under the
          Act and, to such counsel's knowledge, no stop order proceedings with
          respect thereto are pending or threatened under the Act and any
          required filing of the Prospectus, and any supplement thereto pursuant
          to Rule 424 under the Act, has been made in the manner and within the
          time period required by such Rule 424;

               (v) each Delaware Subsidiary is a corporation or other legal
          entity duly formed, existing and in good standing under the laws of
          its jurisdiction of organization. Each Delaware Subsidiary has the
          corporate, trust, partnership or other power to own or hold under
          lease the properties it purports to own or hold under lease and to
          transact the business it transacts and proposes to transact to the
          extent described in the Registration Statement and Prospectus. All of
          the issued and outstanding shares of beneficial ownership or shares of
          capital stock of, or other ownership interests in, each Delaware
          Subsidiary have been duly authorized and validly issued, are fully
          paid and except as to Delaware Subsidiaries that are limited liability
          companies or partnerships, non-assessable; and, to such counsel's
          knowledge, all issued and outstanding shares of beneficial ownership
          or shares of capital stock of, or other ownership interests in, each
          Delaware Subsidiary and each Maryland Subsidiary are owned by the
          Company, directly or through subsidiaries, free and clear of any
          security interest, mortgage, pledge, lien or encumbrance, except as
          disclosed in the Registration Statement and Prospectus;

               (vi) the execution, delivery and performance of this Agreement by
          the Company and the transactions contemplated hereby do not and will
          not result in a Default Event under (nor constitute any event which
          with notice, lapse of time, or both, would result in any breach of, or
          constitute a Default Event under) (A) any provisions of the charter or
          by-laws or other organizational documents of the Delaware
          Subsidiaries, (B) any provision of any agreement or other instrument
          to which the Company or any of the Delaware Subsidiaries is a party or
          by which their respective properties may be bound or affected, that is
          described in the Prospectus or filed as an exhibit to the Registration
          Statement or is otherwise known to such counsel, (C) any federal,
          state, local or foreign law, regulation or rule, or any decree, to
          which the Company or the Delaware Subsidiaries may be subject, other
          than, in the case of clauses (B) and (C), such Default Events as would
          not, individually or in the aggregate, have a Material Adverse Effect;

               (vii) to such counsel's knowledge, there are no contracts,
          licenses, agreements, leases or documents of a character which are
          required to be filed as exhibits to the Registration Statement or to
          be described in the Prospectus which have not been so filed or
          described;

               (viii) to such counsel's knowledge, except as described in the
          Prospectus or as would not, individually or in the aggregate, have a
          Material Adverse Effect, there are no private or governmental actions,
          suits, claims, investigations or proceedings pending, threatened or
          contemplated to which the Company or any of the Delaware Subsidiaries
          or any of their officers is subject or of which any of their
          properties is subject, whether at law, in equity or before or by any
          federal, state, local or foreign governmental or regulatory
          commission, board, body, authority or agency;

                                       17
<Page>

               (ix) to such counsel's knowledge, no person has the right,
          pursuant to the terms of any contract, agreement or other instrument
          described in or filed as an exhibit to the Registration Statement, to
          cause the Company to register under the Act any shares of beneficial
          interest or other equity interests as a result of the filing or
          effectiveness of the Registration Statement or the sale of the Shares
          as contemplated hereby, except for such rights as have been complied
          with or waived; and to the knowledge of such counsel, except as
          described in the Registration Statement and Prospectus, no person is
          entitled to registration rights with respect to shares of capital
          stock or other securities of the Company;

               (x) the Company is not, and after the offering and sale of the
          Shares and the application of the proceeds as described in the
          Prospectus, will not be, an "investment company," or an entity
          controlled by an "investment company," as such terms are defined in
          the Investment Company Act; and

               (xi) to such counsel's knowledge, the statements in the
          Registration Statement and the Prospectus under the captions "Business
          - Communities Leased From Senior Housing and Managed by Sunrise",
          "Business - Our Senior Housing Leases", "Business - Sunrise Management
          Agreements", "Business - Government Regulation and Reimbursement",
          "Business - Environmental Matters" in each case insofar as such
          statements purport to summarize matters arising under Massachusetts or
          New York law or the federal law of the United States, or provisions of
          documents as to which the Company is a party specifically referred to
          therein, are accurate in all material respects.

     Also, such counsel shall state that it has participated in conferences with
officers and other representatives of the Company, representatives of the
independent public accountants of the Company and representatives of the
Underwriters at which the contents of the Registration Statement and Prospectus
were discussed and, although such counsel is not passing upon and does not
assume responsibility for the accuracy, completeness or fairness of the
statements contained in the Registration Statement or Prospectus (except as and
to the extent stated in subparagraph (xi) above), on the basis of the foregoing
nothing has come to the attention of such counsel that causes them to believe
that the Registration Statement or any amendment thereto at the time such
Registration Statement or amendment became effective contained an untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary to make the statements therein not misleading, or
that the Prospectus or any supplement thereto at the date of the Prospectus
Supplement or such other supplement, and at all times up to and including the
time of purchase or additional time of purchase, as the case may be, contained
an untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading (it being
understood that such counsel need express no opinion with respect to the
financial statements and schedules and other financial and statistical data and
exhibits included or incorporated by reference in the Registration Statement or
Prospectus).

          (b) The Company shall furnish to you at the time of purchase and at
     the additional time of purchase, as the case may be, an opinion of Venable
     LLP, special Maryland counsel of the Company, addressed to the
     Underwriters, and dated the time of purchase or the additional time of
     purchase, as the case may be, with reproduced copies for each of the other
     Underwriters and in form satisfactory to Willkie Farr & Gallagher LLP,
     counsel for the Underwriters, stating that:

               (i) the Company has been duly incorporated, is existing as a
          corporation in good standing under the laws of the State of Maryland,
          with corporate power to own, lease and operate its properties and
          conduct its business in all material respects as described in the
          Registration Statement and the Prospectus, to execute and deliver this
          Agreement and to issue, sell and deliver the Shares as herein
          contemplated;

               (ii) each Subsidiary of the Company identified on Schedule D
          hereto (each a "Maryland Subsidiary") is a corporation or other legal
          entity duly formed, existing and in good standing under the laws of
          its jurisdiction of organization. Each Maryland Subsidiary has the
          corporate or other power to own or hold under lease the properties it
          purports to own or hold under lease and to transact the business it
          transacts and proposes to transact. All of the issued and outstanding
          shares of capital stock of each Maryland Subsidiary have been duly
          authorized and validly issued, are fully paid and non-assessable and
          are owned by the Company, directly or through subsidiaries;

               (iii) the execution, delivery and performance of this Agreement
          by the Company and the transactions contemplated hereby and by the
          Registration Statement do not and will not conflict with, or result in
          any breach of, or constitute a default under (nor constitute any event
          which with notice, lapse of time, or both, would result in any breach
          of, or constitute a default under) (A) any provisions of the Articles
          of Amendment and Restatement, charter or by-laws or other
          organizational documents of the Company or any of the Maryland
          Subsidiaries or (B) any local or state Maryland law or administrative
          regulation applicable to the Company and the Maryland Subsidiaries;

               (iv) the Company has authorized and outstanding shares of capital
          stock as set forth in the Registration Statement and the Prospectus;
          the outstanding shares of capital stock of the Company have been duly
          and validly authorized and issued by all necessary corporate action
          and are fully paid, nonassessable and free of any preemptive rights,
          resale rights, rights of first refusal and similar rights under the
          MGCL; the Shares, when issued, will be duly and validly authorized and
          issued by all necessary corporate action, fully paid, nonassessable
          and free of any preemptive rights, resale rights, rights of first
          refusal and similar rights under the MGCL; and the certificates for
          the Shares are in due and proper form and conform in all material
          respects to the requirements of the MGCL;

                                       19
<Page>

               (v) no approval, authorization, consent or order of or filing
          with any Maryland governmental or regulatory commission, board, body,
          authority or agency having jurisdiction over the Company is required
          in connection with the execution, delivery and performance of this
          Agreement, the issuance and sale of the Shares being delivered at the
          time of purchase and at the additional time of purchase, as the case
          may be, and the consummation of the transactions contemplated hereby
          and by the Prospectus (in rendering the opinion expressed in this
          paragraph (v), such counsel need express no opinion concerning the
          securities laws of the State of Maryland.);

               (vi) to such counsel's knowledge, the statements in the
          Registration Statement and the Prospectus under the captions
          "Description of capital stock" and "Material provisions of Maryland
          law, our charter and bylaws" and in each case insofar as such
          statements purport to summarize matters arising under Maryland law are
          accurate in all material respects; and

               (vii) to such counsel's knowledge, neither the Company nor any of
          the Maryland Subsidiaries is in violation of its charter or by-laws or
          other organizational documents or in violation of any local or state
          Maryland law or administrative regulation applicable to the Company
          and the Maryland Subsidiaries.

          (c) You shall have received at the time of purchase and at the
     additional time of purchase, as the case may be, the opinion of Willkie
     Farr & Gallagher LLP, counsel for the Underwriters, dated the time of
     purchase or the additional time of purchase, as the case may be, with
     respect to the issuance and sale of the Shares by the Company, the
     Registration Statement, the Prospectus (together with any supplement
     thereto) and other related matters as the Underwriters may require. In
     addition, Willkie Farr & Gallagher LLP may rely on the opinion of Venable
     LLP as to all matters of Maryland law.

          (d) You shall have received from Ernst & Young LLP letters dated,
     respectively, the date of this Agreement and the time of purchase and
     additional time of purchase, as the case may be, and addressed to the
     Underwriters (with reproduced copies for each of the Underwriters) in the
     forms heretofore approved by Willkie Farr & Gallagher LLP, counsel for the
     Underwriters.

          (e) No amendment or supplement to the Registration Statement or
     Prospectus, or document which upon filing with the Commission would be
     incorporated by reference therein, shall at any time have been filed to
     which you have objected in writing.

          (f) The Registration Statement shall have become effective not later
     than 5:30 PM New York City time on the date of this Agreement and, if Rule
     430A under the Act is used, the Prospectus shall have been filed with the
     Commission pursuant to Rule 424(b) under the Act at or before 5:30 PM New
     York City time on the second full business day after the date of this
     Agreement.

          (g) Prior to the time of purchase or the additional time of purchase,
     as the case may be, (i) no stop order with respect to the effectiveness of
     the Registration Statement shall have been issued under the Act or
     proceedings initiated under Section 8(d) or 8(e) of the Act; (ii) the
     Registration Statement and all amendments thereto, or modifications
     thereof, if any, shall not contain an untrue statement of a material fact
     or omit to state a material fact required to be stated therein or necessary
     to make the statements therein not misleading; and (iii) the Prospectus and
     all amendments or supplements thereto, or modifications thereof, if any,
     shall not contain an untrue statement of a material fact or omit to state a
     material fact required to be stated therein or necessary to make the
     statements therein, in the light of the circumstances under which they are
     made, not misleading.

          (h) Between the time of execution of this Agreement and the time of
     purchase or the additional time of purchase, as the case may be, (i) no
     material and adverse change or any prospective material and adverse change
     (other than as specifically described in the Registration Statement and
     Prospectus), in the business, properties, condition (financial or
     otherwise) or results of operations of the Company and the Subsidiaries,
     taken as a whole, shall occur or become known and (ii) no transaction which
     is material and adverse to the Company and the Subsidiaries of the Company
     taken as a whole shall have been entered into by the Company or any of the
     Subsidiaries.

          (i) You shall have received the letters referred to in Section 3(aa).

          (j) The Company will, at the time of purchase or additional time of
     purchase, as the case may be, deliver to you a certificate signed by two of
     the Company's executive officers to the effect that the representations and
     warranties of the Company as set forth in this Agreement are true and
     correct as of each such date, that the Company has performed such of its
     obligations under this Agreement as are to be performed at or before the
     time of purchase and at or before the additional time of purchase, as the
     case may be, and the conditions set forth in paragraphs (f), (g) and (h) of
     this Section 6 have been met.

          (k) The Shares shall have been approved for listing for quotation on

     purchase or the additional time of purchase, as the case may be.

          (l) The Company shall have furnished to you such other documents and
     certificates as to the accuracy and completeness of any statement in the
     Registration Statement and the Prospectus as of the time of purchase and
     the additional time of purchase, as the case may be, as you may reasonably
     request.

          7. EFFECTIVE DATE OF AGREEMENT; TERMINATION. This Agreement shall
     become effective (i) if Rule 430A under the Act is not used, when you shall
     have received notification of the effectiveness of the Registration
     Statement, or (ii) if Rule 430A under the Act is used, when the parties
     hereto have executed and delivered this Agreement.

                                       21
<Page>

     The obligations of the several Underwriters hereunder shall be subject to
termination in the absolute discretion of you or any group of Underwriters
(which may include you) which has agreed to purchase in the aggregate at least
50% of the Firm Shares (i) if, since the time of execution of this Agreement or
the respective dates as of which information is given in the Registration
Statement and Prospectus, there has been any material adverse and unfavorable
change, financial or otherwise (other than as referred to in the Registration
Statement and Prospectus), in the business, prospects, properties, condition
(financial or otherwise) or results of operations of the Company and the
Subsidiaries taken as a whole, which would, in your judgment or in the judgment
of such group of Underwriters, make it impracticable to market the Shares or
(ii) if, at any time prior to the time of purchase or, with respect to the
purchase of any Additional Shares, the additional time of purchase, as the case
may be, trading in securities on the NYSE, the American Stock Exchange or the
Nasdaq Stock Market Inc. ("Nasdaq") shall have been suspended or limitations or
minimum prices shall have been established on the NYSE, the American Stock
Exchange or the Nasdaq or (iii) if, at any time prior to the time of purchase
or, with respect to the purchase of any Additional Shares, the additional time
of purchase, as the case may be, a banking moratorium shall have been declared
either by the United States or New York State authorities or (iv) if, at any
time prior to the time of purchase or, with respect to the purchase of any
Additional Shares, the additional time of purchase, as the case may be, the
United States shall have declared war in accordance with its constitutional
processes or there shall have occurred any material outbreak or escalation of
hostilities or other national or international calamity or crisis of such
magnitude in its effect on the financial markets of the United States as, in
your judgment or in the judgment of such group of Underwriters, to make it
impracticable to market the Shares.

     If you or any group of Underwriters elects to terminate this Agreement as
provided in this Section 7, the Company and each other Underwriter shall be
notified promptly by letter, telegram or telecopy.

     If the sale to the Underwriters of the Shares, as contemplated by this
Agreement, is not carried out by the Underwriters for any reason permitted under
this Agreement or if such sale is not carried out because the Company shall be
unable to comply with any of the terms of this Agreement, the Company shall not
be under any obligation or liability under this Agreement (except to the extent
provided in Sections 4(l), 5 and 9 hereof), and the Underwriters shall be under
no obligation or liability to the Company under this Agreement (except to the
extent provided in Section 9 hereof) or to one another hereunder.

     8. INCREASE IN UNDERWRITERS' COMMITMENTS. Subject to Sections 6 and 7, if
any Underwriter shall default in its obligation to purchase and pay for the Firm
Shares to be purchased by it hereunder (otherwise than for a reason sufficient
to justify the termination of this Agreement under the provisions of Section 7
hereof) and if the number of Firm Shares which all Underwriters so defaulting
shall have agreed but failed to purchase and pay for does not exceed 10% of the
total number of Firm Shares, the non-defaulting Underwriters shall purchase and
pay for (in addition to the aggregate number of Firm Shares they are obligated
to purchase pursuant to Section 1 hereof) the number of Firm Shares agreed to be
purchased by all such defaulting Underwriters, as hereinafter provided. Such
Firm Shares shall be purchased and paid for by such non-defaulting Underwriter
or Underwriters in such amount or amounts as you may designate with the consent
of each Underwriter so designated or, in the event no such designation is made,

                                       22
<Page>

such Firm Shares shall be purchased and paid for by all non-defaulting
Underwriters pro rata in proportion to the aggregate number of Firm Shares set
opposite the names of such non-defaulting Underwriters in Schedule A.

     Without relieving any defaulting Underwriter from its obligations
hereunder, the Company agrees with the non-defaulting Underwriters that it will
not sell any Firm Shares hereunder unless all of the Firm Shares are purchased
by the Underwriters (or by substituted Underwriters selected by you with the
approval of the Company or selected by the Company with your approval).

     If a new Underwriter or Underwriters are substituted by the Underwriters or
by the Company for a defaulting Underwriter or Underwriters in accordance with
the foregoing provision, the Company or you shall have the right to postpone the
time of purchase for a period not exceeding five business days in order that any
necessary changes in the Registration Statement and Prospectus and other
documents may be effected.

     The term Underwriter as used in this Agreement shall refer to and include
any Underwriter substituted under this Section 8 with like effect as if such
substituted Underwriter had originally been named in Schedule A.

     If the aggregate number of Shares which the defaulting Underwriter or
Underwriters agreed to purchase exceeds 10% of the total number of Shares which
all Underwriters agreed to purchase hereunder, and if neither the non-defaulting
Underwriters nor the Company shall make arrangements within the five business
day period stated above for the purchase of all the Shares which the defaulting
Underwriter or Underwriters agreed to purchase hereunder, this Agreement shall
terminate without further act or deed and without any liability on the part of
the Company to any non-defaulting Underwriter and without any liability on the
part of any non-defaulting Underwriter to the Company. Nothing in this
paragraph, and no action taken hereunder, shall relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.

     9. INDEMNITY AND CONTRIBUTION.

     (a) The Company agrees to indemnify, defend and hold harmless each
Underwriter, its partners, directors, officers, employees and agents and any
person who controls any Underwriter within the meaning of Section 15 of the Act
or Section 20 of the Exchange Act, and the successors and assigns of all of the
foregoing persons from and against any loss, damage, expense, liability or claim
(including the reasonable cost of investigation) which, jointly or severally,
any such Underwriter or any such person may incur under the Act, the Exchange
Act, the common law or otherwise, insofar as such loss, damage, expense,
liability or claim arises out of or is based upon (i) any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement (or in the Registration Statement as amended by any post-effective
amendment thereof by the Company) or in a Prospectus (the term Prospectus for
the purpose of this Section 9 being deemed to include any Preliminary
Prospectus, the Prospectus and the Prospectus as amended or supplemented by the
Company), or arises out of or is based upon any omission or alleged omission to
state a material fact required to be stated in either such Registration
Statement or Prospectus or necessary to make the statements made

                                       23
<Page>

therein not misleading, except insofar as any such loss, damage, expense,
liability or claim arises out of or is based upon any untrue statement or
alleged untrue statement of a material fact contained in and in conformity with
information furnished by or on behalf of any Underwriter through you to the
Company expressly for use with reference to such Underwriter in such
Registration Statement or such Prospectus or arises out of or is based upon any
omission or alleged omission to state a material fact in connection with such
information required to be stated in such Registration Statement or such
Prospectus or necessary to make such information not misleading, (ii) any untrue
statement or alleged untrue statement made by the Company in Section 3 of this
Agreement or the failure by the Company to perform when and as required any
agreement or covenant contained herein or (iii) any untrue statement or alleged
untrue statement of any material fact contained in any audio or visual materials
provided by the Company or based upon written information furnished by or, with
the approval of the Company, on behalf of the Company including, without
limitation, slides, videos, films or tape recordings, used in connection with
the marketing of the Shares; PROVIDED, HOWEVER, that, solely with regard to
clause (i), the foregoing indemnity agreement with respect to any Prospectus or
Preliminary Prospectus shall not inure to the benefit of any Underwriter from
whom the person asserting such losses, claims, damages or liabilities purchased
Shares, or any person controlling the Underwriter, if sufficient copies of the
Prospectus were timely delivered to such Underwriter pursuant to Section 4
hereof and a copy of the Prospectus (as then amended or supplemented if the
Company shall have furnished any amendments or supplements thereto) was not
given or sent to such person, if required by law to have been delivered, at or
prior to the written confirmation of the sale of the Shares to such person, and
if the Prospectus (as so amended or supplemented) would have cured the defect
giving rise to such losses, claims, damages or liabilities.

     If any action, suit or proceeding (together, a "Proceeding") is brought
against an Underwriter or any such person in respect of which indemnity may be
sought against the Company pursuant to the foregoing paragraph, such Underwriter
or such person shall promptly notify the Company in writing of the institution
of such Proceeding and the Company shall assume the defense of such Proceeding,
including the employment of counsel reasonably satisfactory to such indemnified
party and payment of all fees and expenses related thereto; PROVIDED, HOWEVER,
that the omission to so notify the Company shall not relieve the Company from
any liability which the Company may have to any Underwriter or any such person
or otherwise. Such Underwriter or such person shall have the right to employ its
or their own counsel in any such case, but the fees and expenses of such counsel
shall be at the expense of such Underwriter or of such person unless the
employment of such counsel shall have been authorized in writing by the Company
in connection with the defense of such Proceeding or the Company shall not have,
within a reasonable period of time in light of the circumstances, employed
counsel to have charge of the defense of such Proceeding or such indemnified
party or parties shall have reasonably concluded that there may be defenses
available to it or them which are different from, additional to or in conflict
with those available to the Company (in which case the Company shall not have
the right to direct the defense of such Proceeding on behalf of the indemnified
party or parties), in any of which events such fees and expenses shall be borne
by the Company and paid as incurred (it being understood, however, that the
Company shall not be liable for

                                       24
<Page>

the expenses of more than one separate counsel (in addition to any local
counsel) in any one Proceeding or series of related Proceedings in the same
jurisdiction representing the indemnified parties who are parties to such
Proceeding). The Company shall not be liable for any settlement of any
Proceeding effected without its prior written consent, but if settled with the
written consent of the Company, the Company agrees to indemnify and hold
harmless any Underwriter and any such person from and against any loss or
liability by reason of such settlement. Notwithstanding the foregoing sentence,
if at any time an indemnified party shall have requested an indemnifying party
to reimburse the indemnified party for fees and expenses of counsel as
contemplated by the second sentence of this paragraph, then the indemnifying
party agrees that it shall be liable for any settlement of any Proceeding
effected without the Company's written consent if (i) such settlement is entered
into more than 60 business days after receipt by the indemnifying party of the
aforesaid request, (ii) such indemnifying party shall not have reimbursed the
indemnified party in accordance with such request prior to the date of such
settlement and (iii) such indemnified party shall have given the indemnifying
party at least 30 days' prior notice of its intention to settle. No indemnifying
party shall, without the prior written consent of the indemnified party, effect
any settlement of any pending or threatened Proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such Proceeding and does not include an admission
of fault, culpability or a failure to act, by or on behalf of such indemnified
party.

     (b) Each Underwriter severally agrees to indemnify, defend and hold
harmless the Company, its directors, officers, employees and agents and any
person who controls the Company within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act and the successors and assigns of all of the
foregoing persons from and against any loss, damage, expense, liability or claim
(including the reasonable cost of investigation) which, jointly or severally,
the Company or any such person may incur under the Act, the Exchange Act, the
common law or otherwise, insofar as such loss, damage, expense, liability or
claim arises out of or is based upon any untrue statement or alleged untrue
statement of a material fact contained in and in conformity with information
furnished by or on behalf of such Underwriter through you to the Company
expressly for use with reference to such Underwriter in the Registration
Statement (or in the Registration Statement as amended by any post-effective
amendment thereof by the Company) or in a Prospectus, or arises out of or is
based upon any omission or alleged omission to state a material fact in
connection with such information required to be stated in such Registration
Statement or such Prospectus or necessary to make such information not
misleading.

     If any Proceeding is brought against the Company or any such person in
respect of which indemnity may be sought against any Underwriter pursuant to the
foregoing paragraph, the Company or such person shall promptly notify such
Underwriter in writing of the institution of such Proceeding and such
Underwriter shall assume the defense of such Proceeding, including the
employment of counsel reasonably satisfactory to such indemnified party and
payment of all fees and expenses; PROVIDED, HOWEVER, that the omission to so
notify such Underwriter shall not relieve such Underwriter from any liability
which such Underwriter may have to the Company or any such person or otherwise.
The Company or such person shall have the right to employ their or its own
counsel in any such case, but the fees and expenses of such counsel shall be at
the expense of the Company or such person unless the employment of such counsel
shall have been authorized in writing by such Underwriter in connection with the
defense of such Proceeding or such

                                       25
<Page>

Underwriter shall not have employed counsel to defend such Proceeding or such
indemnified party or parties shall have reasonably concluded that there may be
defenses available to it or them which are different from or additional to or in
conflict with those available to such Underwriter (in which case such
Underwriter shall not have the right to direct the defense of such Proceeding on
behalf of the indemnified party or parties, but such Underwriter may employ
counsel and participate in the defense thereof but the fees and expenses of such
counsel shall be at the expense of such Underwriter), in any of which events
such fees and expenses shall be borne by such Underwriter and paid as incurred
(it being understood, however, that such Underwriter shall not be liable for the
expenses of more than one separate counsel (in addition to any local counsel) in
any one Proceeding or series of related Proceedings in the same jurisdiction
representing the indemnified parties who are parties to such Proceeding). No
Underwriter shall be liable for any settlement of any such Proceeding effected
without the written consent of such Underwriter but if settled with the written
consent of such Underwriter, such Underwriter agrees to indemnify and hold
harmless the Company and any such person from and against any loss or liability
by reason of such settlement. Notwithstanding the foregoing sentence, if at any
time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel as contemplated
by the second sentence of this paragraph, then the indemnifying party agrees
that it shall be liable for any settlement of any Proceeding effected without
the Underwriters' written consent if (i) such settlement is entered into more
than 60 business days after receipt by such indemnifying party of the aforesaid
request, (ii) such indemnifying party shall not have reimbursed the indemnified
party in accordance with such request prior to the date of such settlement and
(iii) such indemnified party shall have given the indemnifying party at least 30
days' prior notice of its intention to settle. No indemnifying party shall,
without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened Proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such Proceeding.

     (c) If the indemnification provided for in this Section 9 is unavailable to
an indemnified party under subsections (a) and (b) of this Section 9 in respect
of any losses, damages, expenses, liabilities or claims referred to therein,
then each applicable indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, damages, expenses, liabilities or
claims (i) in such proportion as is appropriate to reflect the relative benefits
received by the Company on the one hand and the Underwriters on the other hand
from the offering of the Shares or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Company on the one hand and of the Underwriters
on the other in connection with the statements or omissions which resulted in
such losses, damages, expenses, liabilities or claims, as well as any other
relevant equitable considerations. The relative benefits received by the Company
on the one hand and the Underwriters on the other shall be deemed to be in the
same respective proportions as the total proceeds from the offering (net of
underwriting discounts and commissions but before deducting expenses) received
by the Company and the total underwriting discounts and commissions received by
the Underwriters, bear to the aggregate public offering price of the Shares. The
relative fault of the Company on the one hand and of the Underwriters on the
other shall be determined by reference to, among other things, whether the
untrue statement or alleged untrue statement of a material fact or

                                       26
<Page>

omission or alleged omission relates to information supplied by the Company or
by the Underwriters and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The amount paid or payable by a party as a result of the losses, damages,
expenses, liabilities and claims referred to in this subsection shall be deemed
to include any legal or other fees or expenses reasonably incurred by such party
in connection with investigating, preparing to defend or defending any
Proceeding.

     (d) The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Section 9 were determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in subsection (c) above. Notwithstanding
the provisions of this Section 9, in no case shall any Underwriter be required
to contribute any amount in excess of the amount by which the total price at
which the Shares underwritten by such Underwriter and distributed to the public
were offered to the public exceeds the amount of any damage which such
Underwriter has otherwise been required to pay by reason of such untrue
statement or alleged untrue statement or omission or alleged omission. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation. The Underwriters' obligations to contribute
pursuant to this Section 9 are several in proportion to their respective
underwriting commitments and not joint.

     (e) The indemnity and contribution agreements contained in this Section 9
and the covenants, warranties and representations of the Company contained in
this Agreement shall remain in full force and effect regardless of any
investigation made by or on behalf of any Underwriter, its partners, directors,
officers, employees or agents or any person (including each partner, officer,
director, employee or agent of such person) who controls any Underwriter within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act, or by or
on behalf of the Company, its directors, officers, employees or agents or any
person who controls any of the foregoing within the meaning of Section 15 of the
Act or Section 20 of the Exchange Act, and shall survive any termination of this
Agreement or the issuance and delivery of the Shares. The Company and each
Underwriter agree promptly to notify each other of the commencement of any
Proceeding against it and against any of the officers, directors, employees or
agents of the Company in connection with the issuance and sale of the Shares, or
in connection with the Registration Statement or Prospectus.

     10. NOTICES. Except as otherwise herein provided, all statements, requests,
notices and agreements shall be in writing or by telegram and, if to the
Underwriters, shall be sufficient in all respects if delivered or sent to UBS
Securities LLC, 299 Park Avenue, New York, NY 10171-0026, Attention: Syndicate
Department; and if to the Company, shall be sufficient in all respects if
delivered or sent to the Company at the offices of the Company at 400 Centre
Street, Newton, Massachusetts 02458, Attention: Evrett W. Benton, Chief
Executive Officer and President.

     11. INFORMATION FURNISHED BY THE UNDERWRITERS. The statements set forth in
the last sentence on the cover page of the Prospectus, the Underwriters listed

respective participation in the sale of the Shares set forth under the caption
"Underwriting" in the Prospectus, the statements set forth in

                                       27
<Page>

the two sentences immediately preceding the caption "Underwriting -
Over-allotment Option" in the Prospectus, the statements set forth in the first
paragraph and the last sentence of the second paragraph under the caption
"Underwriting - Commissions and Discounts" in the Prospectus and the statements
set forth under the caption "Underwriting - Price Stabilization, Short

information furnished by or on behalf of the Underwriters as such information is
referred to in Sections 3 and 9 hereof.

     12. GOVERNING LAW; CONSTRUCTION. This Agreement and any claim, counterclaim
or dispute of any kind or nature whatsoever arising out of or in any way
relating to this Agreement ("Claim"), directly or indirectly, shall be governed
by, and construed in accordance with, the laws of the State of New York. The
Section headings in this Agreement have been inserted as a matter of convenience
of reference and are not a part of this Agreement.

     13. SUBMISSION TO JURISDICTION. Except as set forth below, no Claim may be
commenced, prosecuted or continued in any court other than the courts of the
State of New York located in the City and County of New York or in the United
States District Court for the Southern District of New York, which courts shall
have jurisdiction over the adjudication of such matters, and you and the Company
consent to the jurisdiction of such courts and personal service with respect
thereto. The Company hereby consents to personal jurisdiction, service and venue
in any court in which any Claim arising out of or in any way relating to this
Agreement is brought by any third party against an Underwriter or any
indemnified party. Each Underwriter and the Company (on its behalf and, to the
extent permitted by applicable law, on behalf of its stockholders and
affiliates) waives all right to trial by jury in any action, proceeding or
counterclaim (whether based upon contract, tort or otherwise) in any way arising
out of or relating to this Agreement. The Company agrees that a final judgment
in any such action, proceeding or counterclaim brought in any such court shall
be conclusive and binding thereupon, and may be enforced in any other courts in
the jurisdiction to which the Company is or may be subject, by suit upon such
judgment.

     14. PARTIES AT INTEREST. The Agreement herein set forth has been and is
made solely for the benefit of the Underwriters, the Company and, to the extent
provided in Section 9 hereof, the controlling persons, directors, officers,
employees and agents referred to in such section, and their respective
successors, assigns, heirs, personal representatives and executors and
administrators. No other person, partnership, association or corporation
(including a purchaser, as such purchaser, from any of the Underwriters) shall
acquire or have any right under or by virtue of this Agreement.

     15. COUNTERPARTS. This Agreement may be signed by the parties in one or
more counterparts which together shall constitute one and the same agreement
among the parties.

     16. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the
Underwriters and the Company and their successors and assigns and any successor
or assign of any substantial portion of the Company's and any of the
Underwriters' respective businesses and/or assets.

     17. MISCELLANEOUS. UBS Securities LLC, an indirect, wholly owned subsidiary
of UBS AG, is not a bank and is separate from any affiliated bank, including any
U.S.

                                       28
<Page>

branch or agency of UBS Securities LLC. Because UBS Securities LLC is a
separately organized entity, it is solely responsible for its own contractual
obligations and commitments, including obligations with respect to sales and
purchases of securities. Securities sold, offered or recommended by UBS
Securities LLC are not deposits, are not insured by the Federal Deposit
Insurance Corporation, are not guaranteed by a branch or agency, and are not
otherwise an obligation or responsibility of a branch or agency.

     A lending affiliate of UBS Securities LLC may have lending relationships
with issuers of securities underwritten or privately placed by UBS Securities
LLC. To the extent required under the securities laws, prospectuses and other
disclosure documents for securities underwritten or privately placed by UBS
Securities LLC will disclose the existence of any such lending relationships and
whether the proceeds of the issue will be used to repay debts owed to affiliates
of UBS Securities LLC.
