ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
    
 
     The Company is a Massachusetts corporation. Reference is made to Chapter
156B, Section 13 of the Massachusetts Business Corporation Law (the "MBCL"),
which enables a corporation in its original articles of organization or an
amendment thereto to eliminate or limit the personal liability of a director for
monetary damages for violations of the director's fiduciary duty, except (i) for
any breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) pursuant to Sections
61 and 62 of the MBCL (providing for liability of directors for authorizing
unauthorized distributions and for making loans to directors, officers and
certain shareholders) or (iv) for any transaction from which a director derived
an improper personal benefit.
 
     Reference also is made to Chapter 156B, Section 67 of the MBCL, which
provides that a corporation may indemnify directors, officers, employees and
other agents and persons who serve at its request as directors, officers,
employees or other agents of another organization or who serve at its request in
any capacity with respect to any employee benefit plan, to the extent specified
or authorized by the articles of organization, a by-law adopted by the
stockholders or a vote adopted by the holders of a majority of the shares of
stock entitled to vote on the election of directors. Such indemnification may
include payment by the corporation of expenses incurred in defending a civil or
criminal action or proceeding in advance of the final disposition of such action
or proceeding, upon receipt of an undertaking by the person indemnified to repay
such payment if he shall be adjudicated to be not entitled to indemnification
under Section 67 which undertaking may be accepted without reference to the
financial ability of such person to make repayment. Any such indemnification may
be provided although the person to be indemnified is no longer an officer,
director, employee or agent of the corporation or of such other organization or
no longer serves with respect to any such employee benefit plan. No
indemnification shall be provided, however, for any person with respect to any
matter as to which he shall have been adjudicated in any proceeding not to have
acted in good faith in the reasonable belief that his action was in the best
interest of the corporation or to the extent that such matter relates to service
with respect to an employee benefit plan, in the best interest of the
participants or beneficiaries of such employee benefit plan.
 
     Article VI.D of the Restated Articles of Organization of the Company
provides that, except under certain circumstances, directors of the Company
shall not be personally liable to the Company or its stockholders for monetary
damages for breach of fiduciary duties as a director.

     Article IV of the By-laws of the Company provides for indemnification of
the officers and directors of the Company to the full extent provided by
applicable law.

ITEM 17. UNDERTAKINGS.
    
 
     (a) The registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the registrant's
annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act
of 1934 that is incorporated by reference in the Registration Statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     (b) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the provisions described under Item 15 above, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer,
or controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.
 
     (c) The undersigned registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this Registration Statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

               (i) The Company meets the requirements for use of Form S-3 under

Securities, as amended at the time when it was or is declared effective,
including (A) all financial schedules and exhibits thereto, (B) all documents

Prospectus incorporated therein at the time such Registration Statement becomes
effective); the term "Registration Statement" includes both the Original
Registration Statement and any Rule 462(b) Registration Statement; the term
"Preliminary Prospectus" means each prospectus subject to completion filed with

          Sheet relating to the Securities that is first filed pursuant to Rule
          424(b)(7) under the Act, together with the Preliminary Prospectus
          identified therein that such Term Sheet supplements;

               (B) if the Company does not rely on Rule 434 under the Act, the
          prospectus first filed with the Commission pursuant to Rule 424(b)
          under the Act; or

          sheet that satisfies the requirements of Rule 434 under the Act. Any

          case may be; any reference herein to the "date" of a Prospectus that
          includes a Term Sheet shall mean the date of such Term Sheet. For
          purposes of the preceding sentence, any reference to the "effective

          the Exchange Act of a document incorporated by reference in such
          registration statement, be deemed to refer to the date on which such
          document was so filed with the Commission.

               (ii) The Commission has not issued any order preventing or
     suspending the use of any Preliminary Prospectus. When any Preliminary

     untrue statement of 

                                      3
<PAGE>   4
     a material fact or omit to state any material fact necessary in order
     to make the statements therein, in the light of the circumstances under
     which they were made, not misleading. When the Registration Statement or
     any amendment thereto was or is declared effective, it (A) contained or
     will contain all statements required to be stated therein in accordance

     requirements of, the Act, the Exchange Act and the respective rules and
     regulations of the Commission thereunder and (B) did not or will not
     include any untrue statement of a material fact or omit to state any
     material fact necessary to make the statements therein not misleading.
     When the Prospectus or any Term Sheet that is a part thereof or any
     Integrated Prospectus or any amendment or supplement thereto is filed with
     the Commission pursuant to Rule 424(b) (or, if the Prospectus or part
     thereof or such amendment or supplement is not required to be so filed,
     when the Registration Statement or the amendment thereto containing such
     amendment or supplement to the Prospectus was or is declared effective),
     on the date when the Prospectus is otherwise amended or supplemented and
     on the Firm Closing Date and any Option Closing Date (both as hereinafter
     defined), each of the Prospectus, and, if required to be filed pursuant to
     Rules 434(c)(2) and 424(b) under the Act, the Integrated Prospectus as
     amended or supplemented at any such time, (A) contained or will contain
     all statements required to be stated therein in accordance with, and
     complied or will comply in all material respects with the requirements of,
     the Act, the Exchange Act and the respective rules and regulations of the
     Commission thereunder and (B) did not or will not include any untrue
     statement of a material fact or omit to state any material fact necessary
     in order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading. The foregoing provisions of
     this paragraph (ii) do not apply to statements or omissions made in any
     Preliminary Prospectus or any amendment or supplement thereto, the
     Registration Statement or any amendment thereto, the Prospectus or, if
     required to be filed pursuant to Rules 434(c)(2) and 424(b) and the Act,
     the Integrated Prospectus or any amendment or supplement thereto in
     reliance upon and in conformity with written information furnished to the
     Company by any Underwriter through the Representatives specifically for
     use therein.

               (iii) If the Company has elected to rely on Rule 462(b) and the
     Rule 462(b) Registration Statement has not been declared effective (A) the
     Company has filed a Rule 462(b) Registration Statement in compliance with
     and that is effective upon filing pursuant to Rule 462(b) and has received

     organized and are validly existing as corporations in good standing under
     the laws of their respective jurisdictions of incorporation and are duly
     qualified to transact business as foreign corporations and are in good
     standing under the laws of all other jurisdictions where the ownership or
     leasing of their respective properties or the conduct of their respective
     businesses requires such qualification, except where the failure to be so
     qualified does not

     security interests, liens, encumbrances, equities or claims.

               (vii) The Company has an authorized, issued and outstanding

     Preliminary Prospectus). All of the issued shares of capital stock of the
     Company have been duly authorized and validly issued and are fully paid and
     nonassessable. The Firm Securities and the Option Securities have been duly
     authorized and at the Firm Closing Date or the related Option Closing Date
     (as the case may be), after payment therefor in accordance herewith, will
     be validly issued, fully paid and nonassessable. No holders of outstanding
     shares of capital stock of the Company are entitled as such to any
     preemptive or other rights to subscribe for any of the Securities, and no
     holder of securities of the Company has any right which has not been fully
     exercised or waived to require the Company to register the offer or sale of
     any securities owned by such holder under the Act in the public offering

               (xxvii) Neither the Company nor its subsidiaries own any items of
     real property and each of them has marketable title to all tangible
     personal property owned by each of them, in each case free and clear of any
     security interests, liens, encumbrances, equities, claims and other
     defects, except such as do not materially and adversely affect the value of
     such property and do not interfere with the use made or proposed to be made
     of such property by the Company or such subsidiary, and any real property
     and buildings held under lease by the Company or any such subsidiary are
     held under valid, subsisting and enforceable leases, with such exceptions
     as are not material and do not interfere with the use made or proposed to
     be made of such property and buildings by the Company or such subsidiary,
     in each case except as described in or contemplated by each of the
     Prospectus and any Integrated Prospectus (or, if the Prospectus and any
     required Integrated Prospectus are not in existence, the most recent
     Preliminary Prospectus).

               (xxviii) No labor dispute with the employees of the Company or
     any of its subsidiaries exists or, to the Company's and the Selling
     Securityholders' knowledge, is threatened or imminent that could result in
     a material adverse change in the condition (financial or otherwise),
     business prospects, net worth or results of operations of the Company and
     its subsidiaries, except as described in or contemplated by each of the
     Prospectus and any Integrated Prospectus (or, if the Prospectus and any
     required Integrated Prospectus are not in existence, the most recent
     Preliminary Prospectus).

               (xxix) The Company and each of its subsidiaries are insured by
     insurers of recognized financial responsibility against such losses and
     risks and in such amounts as are reasonably considered by the Company to be
     prudent and customary in the businesses in which they are engaged; neither
     the Company nor any subsidiary has been refused any insurance coverage
     sought or applied for; and neither the Company nor any subsidiary has any
     reason to believe that it will not be able to renew its existing insurance
     coverage as and when such coverage expires or to obtain similar coverage
     from similar insurers as may be necessary to continue its business at a
     cost that would not materially and adversely affect the condition
     (financial or otherwise), business prospects, net worth or results of
     operations of the Company and its subsidiaries, except as described in or
     contemplated by each of the Prospectus and any Integrated Prospectus (or,
     if the Prospectus and any required Integrated Prospectus are not in
     existence, the most recent Preliminary Prospectus).

               (xxx) No subsidiary of the Company is currently prohibited,
     directly or indirectly, from paying any dividends to the Company, from
     making any other distribution on such subsidiary's capital stock, from
     repaying to the Company any loans or advances to such subsidiary from the
     Company or from transferring any of such subsidiary's property or assets to
     the Company or any other subsidiary of the Company, except as described in
     or contemplated by each of the Prospectus and any Integrated Prospectus
     (or, if the Prospectus and any required Integrated Prospectus are not in
     existence, the most recent Preliminary Prospectus).

               (xxxi) Each certificate signed by any officer of the Company and
     delivered to the Representatives or counsel for the Underwriters pursuant
     to this Agreement shall be

                                       10

<PAGE>   11


     deemed to be a representation and warranty by the Company to each
     Underwriter as to the matters covered thereby.

               (xxxii) The Company and its subsidiaries own or possess, or can
     acquire on reasonable terms, all material patents, patent applications,
     trademarks, service marks, trade names, licenses, copyrights and
     proprietary or other confidential information (collectively, the
     "Intellectual Property") currently employed by them in connection with
     their respective businesses, and neither the Company nor any such
     subsidiary has received any notice of infringement of or conflict with
     asserted rights of any third party with respect to any of the foregoing
     which, singly or in the aggregate, if the subject of an unfavorable
     decision, ruling or finding, would result in a material adverse change in
     the condition (financial or otherwise), business prospects, net worth or
     results of operations of the Company and its subsidiaries, except as
     described in or contemplated by each of the Prospectus and any Integrated
     Prospectus (or, if the Prospectus and any required Integrated Prospectus
     are not in existence, the most recent Preliminary Prospectus).

               (xxxiii) All patents, patent applications, trademark
     registrations, trademark applications and registered copyrights which are
     owned by the Company and its subsidiaries have been duly registered in,
     filed in or issued by the United States Patent and Trademark Office, the
     United States Register of Copyrights, or the corresponding offices of other
     jurisdictions, and have been properly maintained and renewed in accordance
     with all applicable provisions of law and administrative regulations of the
     United States and each such jurisdiction.

               (xxxiv) All licenses or other agreements under which the Company
     or its subsidiaries are granted rights in Intellectual Property are in full
     force and effect, except for those licenses or other agreements which are
     not material to the Company or its subsidiaries and there is no default by
     any party thereto which default could reasonably be expected to result in
     a material adverse change in the condition (financial or otherwise),
     business prospects, net worth or results of operations of the Company and
     its subsidiaries. To the Company's and the Selling Securityholders'
     knowledge, the licensors under said licenses and other agreements have and
     had all requisite power and authority to grant the rights purported to be
     conferred thereby, to the extent material with respect to the Company and
     its subsidiaries. All licenses or other agreements under which the Company
     or its subsidiaries have granted rights to others in Intellectual Property
     owned or licensed by the Company or its subsidiaries are in full force and
     effect, except for those licenses or other agreements which are not
     material to the Company or its subsidiaries and there is no default by any
     party thereto which default could reasonably be expected to result in a
     material adverse change in the condition (financial or otherwise), business
     prospects, net worth or results of operations of the Company and its
     subsidiaries.

               (xxxv) The Company and its subsidiaries have taken reasonable
     steps in accordance with sound business practice to establish and preserve
     its ownership of all material Intellectual Property rights with respect to
     its products, services and technology. Except for those instances which
     could not reasonably be expected to have a material adverse effect on the
     condition (financial or otherwise), business prospects, net worth or

                                       11
<PAGE>   12



     results of operations of the Company and its subsidiaries, the Company and
     its subsidiaries have required all employees having access to non-public
     information of the Company and its subsidiaries to execute agreements under
     which such employees are required to convey to the Company ownership of all
     inventions and developments conceived or created by them in the course of
     their employment and to maintain the confidentiality of all such
     information of the Company. Except for those instances which could not
     reasonably be expected to have a material adverse effect on the condition
     (financial or otherwise), business prospects, net worth or results of
     operations of the Company and its subsidiaries, the Company and its
     subsidiaries have not made any such information available to any person
     other than employees of the Company or its subsidiaries except pursuant to
     written agreements requiring the recipients to maintain the confidentiality
     of such information and appropriately restricting the use thereof. The
     Company has no knowledge of any infringement by others of any Intellectual
     Property rights of the Company or its subsidiaries which infringement could
     reasonably be expected to result in a material adverse change in the
     condition (financial or otherwise), business prospects, net worth or
     results of operations of the Company and its subsidiaries.

          (b) Each of the Selling Securityholders represents and warrants to,
and agrees with, each of the several Underwriters that:

               (i) Such Selling Securityholder has full legal right and power to
     enter into this Agreement and to sell, assign, transfer and deliver to the
     Underwriters the Securities to be sold by such Selling Securityholder
     hereunder in accordance with the terms of this Agreement; and this
     Agreement has been duly executed and delivered by such Selling
     Securityholder, and is the valid and binding agreement of such Selling
     Securityholder, enforceable against such Selling Securityholder in
     accordance with its terms.

               (ii) Such Selling Securityholder has duly executed and delivered
     a power of attorney and custody agreement (with respect to such Selling
     Securityholder, the "Power-of-Attorney" and the "Custody Agreement",
     respectively), each in the form heretofore delivered to the
     Representatives, appointing Eric R. Giler and Robert C. Leahy as such
     Selling Securityholder's attorneys-in-fact (the "Attorneys-in-Fact") with
     authority to execute, deliver and perform this Agreement on behalf of such
     Selling Securityholder and appointing Fleet National Bank as custodian
     thereunder (the "Custodian"). Certificates in negotiable form, endorsed in
     blank or accompanied by blank stock powers duly executed, with signatures
     appropriately guaranteed, representing the Securities to be sold by such
     Selling Securityholder hereunder, have been deposited with the Custodian
     pursuant to the Custody Agreement for the purpose of delivery pursuant to
     this Agreement. Such Selling Securityholder has full legal right and power
     to enter into the Custody Agreement and the Power-of-Attorney and to
     perform its obligations under the Custody Agreement. The Custody Agreement
     and the Power-of-Attorney have been duly executed and delivered by such
     Selling Securityholder and, assuming due authorization, execution and
     delivery by the Custodian, are the legal, valid, binding and enforceable
     instruments of such Selling Securityholder. Such Selling Securityholder
     agrees that each of the Securities represented by the certificates on
     deposit with the Custodian is subject to

                                       12

<PAGE>   13



     the interests of the Underwriters hereunder, that the arrangements made for
     such custody, the appointment of the Attorneys-in-Fact and the right, power
     and authority of the Attorneys-in-Fact to execute and deliver this
     Agreement, to agree on the price at which the Securities (including such
     Selling Securityholder's Securities) are to be sold to the Underwriters,
     and to carry out the terms of this Agreement, are to that extent
     irrevocable and that the obligations of such Selling Securityholder
     hereunder shall not be terminated, except as provided in this Agreement or
     the Custody Agreement, by any act of such Selling Securityholder, by
     operation of law or otherwise, whether in the case of any individual
     Selling Securityholder by the death or incapacity of such Selling
     Securityholder, in the case of a trust or estate by the death of the
     trustee or trustees or the executor or executors or the termination of such
     trust or estate, or in the case of a corporate or partnership Selling
     Securityholder by its liquidation or dissolution, or by the occurrence of
     any other event. If any individual Selling Securityholder, trustee or
     executor should die or become incapacitated or any such trust should be
     terminated, or any corporate or partnership Selling Securityholder shall
     liquidate or dissolve, or if any other event should occur, before the
     delivery of such Securities hereunder, the certificates for such Securities
     deposited with the Custodian shall be delivered by the Custodian in
     accordance with the respective terms and conditions of this Agreement as if
     such death, incapacity, termination, liquidation or dissolution or other
     event had not occurred, regardless of whether or not the Custodian or the
     Attorneys-in-Fact shall have received notice thereof.

               (iii) Such Selling Securityholder is the lawful owner of the
     Securities to be sold by the such Selling Securityholder hereunder and upon
     sale and delivery of, and payment for, such Securities, as provided herein,
     such Selling Securityholder will convey good and marketable title to such
     Securities, free and clear of any security interests, liens, encumbrances,
     equities or claims.

               (iv) Such Selling Securityholder has not, directly or indirectly
     (except for the sale of Securities by such Selling Securityholder under
     this Agreement), (A) taken any action designed to cause or result in, or
     that has constituted or which might reasonably be expected to constitute,
     the stabilization or manipulation of the price of any security of the
     Company to facilitate the sale or resale of the Securities or (B) since the
     filing of the Registration Statement (1) sold, bid for, purchased, or paid
     anyone any compensation for soliciting purchases of, the Securities or (2)
     paid or agreed to pay to any person any compensation for soliciting another
     to purchase any other securities of the Company.

               (v) Such Selling Securityholder has not distributed and, prior to
     the later of (A) the Closing Date and (B) the completion of the
     distribution of the Securities, will not distribute any offering material
     in connection with the offering and sale of the Securities other than the
     Registration Statement or any amendment thereto, any Preliminary
     Prospectus, the Prospectus and any Integrated Prospectus or any amendment
     or supplement thereto, or other materials, if any, permitted by the Act.

               (vi) In order to document the Underwriters' compliance with the
     reporting and withholding provisions of the Internal Revenue Code of 1986,
     as amended,

                                       13
<PAGE>   14


     with respect to the transactions herein contemplated, such Selling
     Securityholder agrees to deliver to you prior to or on the Firm Closing
     Date, as hereinafter defined, a properly completed and executed United
     States Treasury Department Form W-8 or W-9 (or other applicable form of
     statement specified by Treasury Department regulations in lieu thereof).

               (vii) Such Selling Securityholder has reviewed the Prospectus,
     any Integrated Prospectus (or, if the Prospectus and any required
     Integrated Prospectus are not in existence, the most recent Preliminary
     Prospectus) and the Registration Statement, and the information regarding
     such Selling Securityholder set forth therein under the caption "Principal
     and Selling Stockholders" is complete and accurate.

               (viii) The sale by such Selling Securityholder of Securities
     pursuant hereto is not prompted by any adverse information concerning the
     Company that is not set forth in the Registration Statement, the Prospectus
     or any Integrated Prospectus (or, if the Prospectus and any required
     Integrated Prospectus are not in existence, the most recent Preliminary
     Prospectus).

               (ix) The sale of the Securities by such Selling Securityholder
     pursuant to this Agreement, the compliance by such Selling Securityholder
     with the other provisions of this Agreement, the Custody Agreement and the
     consummation of the other transactions herein contemplated do not (A)
     require the consent, approval, authorization, registration or qualification
     of or with any governmental authority, except such as have been obtained,
     such as may be required under state securities or blue sky laws and, if the
     registration statement filed with respect to the Securities (as amended) is
     not effective under the Act as of the time of execution hereof, such as may
     be required (and shall be obtained as provided in this Agreement) under the
     Act, or (B) conflict with or result in a breach or violation of any of the
     terms and provisions of, or constitute a default under any indenture,
     mortgage, deed of trust, lease or other agreement or instrument to which
     such Selling Securityholder is a party or by which such Selling
     Securityholder or any of such Selling Securityholder's properties are
     bound, or any statute or any judgment, decree, order, rule or regulation of
     any court or other governmental authority or any arbitrator applicable to
     such Selling Securityholder.

               (x) The representations and warranties of the Company contained
     in Section 2(a) of this Agreement are true and correct.

     3. Purchase, Sale and Delivery of the Securities.
        ---------------------------------------------

     (a) On the basis of the representations, warranties, agreements and
covenants herein contained and subject to the terms and conditions herein set
forth, the Company and the Selling Securityholders agree, severally and not
jointly, to issue and sell to each of the Underwriters, and each of the
Underwriters, severally and not jointly, agrees to purchase from the Company and
the Selling Securityholders, at a purchase price of $____ per share, the number
of Firm Securities set forth opposite the name of such Underwriter in Schedule 1
hereto. The Company agrees to issue and sell to the Underwriters 1,445,029 Firm
Securities and each Selling Securityholder agrees to sell to the Underwriters
the number of Firm Securities set forth opposite

                                       14
<PAGE>   15


such Selling Securityholder's name on Schedule 2 hereto. One or more
certificates in definitive form for the Firm Securities that the several
Underwriters have agreed to purchase hereunder, and in such denomination or
denominations and registered in such name or names as the Representatives
request upon notice to the Company at least 48 hours prior to the Firm Closing
Date, shall be delivered by or on behalf of the Company and the Selling
Securityholders to the Representatives for the respective accounts of the
Underwriters, against payment by or on behalf of the Underwriters of the
respective aggregate purchase prices therefor by wire transfer in same-day funds
(the "Wired Funds") to the respective accounts of the Company and the Selling
Securityholders. Such delivery of and payment for the Firm Securities shall be
made at the offices of Goodwin, Procter & Hoar LLP, Exchange Place, Boston,
Massachusetts, at 9:30 A.M., New York City time, on     , 1996, or at such other
place, time or date as the Representatives, the Company and the Selling
Securityholders may agree upon or as the Representatives may determine pursuant
to Section 9 hereof, such time and date of delivery against payment being herein
referred to as the "Firm Closing Date". The Company and the Selling
Securityholders will make such certificate or certificates for the Firm
Securities available for checking and packaging by the Representatives at the
offices in New York, New York of the Company's transfer agent or registrar or of
Prudential Securities Incorporated at least 24 hours prior to the Firm Closing
Date.

     (b) For the purpose of covering any over-allotments in connection with the
distribution and sale of the Firm Securities as contemplated by the Prospectus,
the Company hereby grants to the several Underwriters an option to purchase,
severally and not jointly, the Option Securities. The purchase price to be paid
for any Option Securities shall be the same price per share as the price per
share for the Firm Securities set forth above in paragraph (a) of this Section
3, plus if the purchase and sale of any Option Securities takes place after the
Firm Closing Date and after the Firm Securities are trading "ex-dividend", an
amount equal to the dividend payable on such Option Securities. The option
granted hereby may be exercised as to all or any part of the Option Securities
from time to time within thirty days after the date of the Prospectus (or, if
such 30th day shall be a Saturday or Sunday or a holiday, on the next business
day thereafter when the New York Stock Exchange is open for trading). The
Underwriters shall not be under any obligation to purchase any of the Option
Securities prior to the exercise of such option. The Representatives may from
time to time exercise the option granted hereby by giving notice in writing or
by telephone (confirmed in writing) to the Company setting forth the aggregate
principal amount of Option Securities as to which the several Underwriters are
then exercising the option and the date and time for delivery of and payment for
such Option Securities. Any such date of delivery shall be determined by the
Representatives but shall not be earlier than two business days or later than
five business days after such exercise of the option and, in any event, shall
not be earlier than the Firm Closing Date. The time and date set forth in such
notice, or such other time on such other date as the Representatives and the
Company may agree upon or as the Representatives may determine pursuant to
Section 9 hereof, is herein called the "Option Closing Date" with respect to
such Option Securities. Upon exercise of the option as provided herein, the
Company shall become obligated to sell to each of the several Underwriters, and,
subject to the terms and conditions herein set forth, each of the Underwriters
(severally and not jointly) shall become obligated to purchase from the Company,
the same percentage of the total number of the Option Securities as to which the
several Underwriters are then exercising the option as such Underwriter is
obligated to purchase of the aggregate number of Firm Securities,

                                       15

<PAGE>   16


as adjusted by the Representatives in such manner as they deem advisable to
avoid fractional shares. If the option is exercised as to all or any portion of
the Option Securities, one or more certificates in definitive form for such
Option Securities, and payment therefor, shall be delivered on the related
Option Closing Date in the manner, and upon the terms and conditions, set forth
in paragraph (a) of this Section 3, except that reference therein to the Firm
Securities and the Firm Closing Date shall be deemed, for purposes of this
paragraph (b), to refer to such Option Securities and Option Closing Date,
respectively.

     (c) The Company and the Selling Securityholders hereby acknowledge that the
wire transfer by or on behalf of the Underwriters of the purchase price for any
Securities does not constitute closing of a purchase and sale of the Securities.
Only execution and delivery of a receipt for Securities by the Underwriters
indicates completion of the closing of a purchase of the Securities from the
Company or the Selling Securityholders, as the case may be. Furthermore, in the
event that the Underwriters wire funds to the Company or any Selling
Securityholder prior to the completion of the closing of a purchase of
Securities, the Company and the Selling Securityholders hereby acknowledge that
until the Underwriters execute and deliver a receipt for the Securities, by
facsimile or otherwise, the Company and any Selling Securityholder, as the case
may be, will not be entitled to the wired funds and shall return the wired funds
to the Underwriters as soon as practicable (by wire transfer of same-day funds)
upon demand. In the event that the closing of a purchase of Securities is not
completed and the wired funds are not returned by the Company and any Selling
Securityholder, as the case may be, to the Underwriters on the same day the
wired funds were received by the Company or such Selling Securityholder, the
Company and any Selling Securityholder, as the case may be, agree to pay to the
Underwriters in respect of each day the wired funds are not returned by it, in
same-day funds, interest on the amount of such wired funds in an amount
representing the Underwriters' cost of financing as reasonably determined by
Prudential Securities Incorporated.

     (d) It is understood that any of you, individually and not as one of the
Representatives, may (but shall not be obligated to) make payment on behalf of
any Underwriter or Underwriters for any of the Securities to be purchased by
such Underwriter or Underwriters. No such payment shall relieve such Underwriter
or Underwriters from any of its or their obligations hereunder.

     4. OFFERING BY THE UNDERWRITERS. Upon your authorization of the release of
the Firm Securities, the several Underwriters propose to offer the Firm
Securities for sale to the public upon the terms set forth in the Prospectus.

     5. COVENANTS OF THE COMPANY AND THE SELLING SECURITYHOLDERS.

     (a) The Company covenants and agrees with each of the Underwriters that:

          (i) The Company will use its best efforts to cause the Registration
     Statement, if not effective at the time of execution of this Agreement, and
     any amendments thereto to become effective as promptly as possible. If
     required, the Company will file each of the Prospectus and any Integrated
     Prospectus and any amendment or supplement thereto or any Term Sheet that
     constitutes a part thereof with

                                       16
<PAGE>   17


     the Commission in the manner and within the time period required by Rule
     434 and 424(b) under the Act. During any time when a prospectus relating to
     the Securities is required to be delivered under the Act, the Company (A)
     will comply with all requirements imposed upon it by the Act, the Exchange
     Act and the Trust Indenture Act and the respective rules and regulations of
     the Commission thereunder to the extent necessary to permit the continuance
     of sales of or dealings in the Securities in accordance with the provisions
     hereof and of each of the Prospectus and any Integrated Prospectus, as then
     amended or supplemented, and (B) will not file with the Commission the
     prospectus or the amendment referred to in the third sentence of Section
     2(a) hereof, any amendment or supplement to such prospectus or any
     amendment to the Registration Statement or any Rule 462(b) Registration
     Statement of which the Representatives shall not previously have been
     advised and furnished with a copy for a reasonable period of time prior to
     the proposed filing and as to which filing the Representatives shall not
     have given their consent. The Company will prepare and file with the
     Commission, in accordance with the rules and regulations of the Commission,
     promptly upon reasonable request by the Representatives or counsel for the
     Underwriters, any amendments to the Registration Statement or amendments or
     supplements to the Prospectus and any Integrated Prospectus that may be
     necessary or advisable in connection with the distribution of the
     Securities by the several Underwriters, and will use its best efforts to
     cause any such amendment to the Registration Statement to be declared
     effective by the Commission as promptly as possible. The Company will
     advise the Representatives, promptly after receiving notice thereof, of the
     time when the Registration Statement or any amendment thereto has been
     filed or declared effective or the Prospectus and any Integrated Prospectus
     or any amendment or supplement thereto has been filed and will provide
     evidence satisfactory to the Representatives of each such filing or
     effectiveness.

          (ii) The Company will advise the Representatives, promptly after
     receiving notice or obtaining knowledge thereof, of (A) the issuance by the
     Commission of any stop order suspending the effectiveness of the Original
     Registration Statement or any Rule 462(b) Registration Statement or any
     post-effective amendment thereto or any order directed at any document
     incorporated by reference in the Registration Statement or if the
     Prospectus and any required Integrated Prospectus are or any amendment or
     supplement thereto or any order preventing or suspending the use of any
     Preliminary Prospectus with the Prospectus and any Integrated Prospectus or
     any amendment or supplement thereto, (B) the suspension of the
     qualification of the Securities for offering or sale in any jurisdiction,
     (C) the institution, threatening or contemplation of any proceeding for any
     such purpose or (D) any request made by the Commission for amending the
     Original Registration Statement or any Rule 462(b) Registration Statement,
     for amending or supplementing any Preliminary Prospectus, the Prospectus
     and any Integrated Prospectus or for additional information. The Company
     will use its best efforts to prevent the issuance of any such stop order
     and, if any such stop order is issued, to obtain the withdrawal thereof as
     promptly as possible.

          (iii) The Company will arrange for the qualification of the Securities
     for offering and sale under the securities or blue sky laws of such
     jurisdictions as the Representatives may designate and will continue such
     qualifications in effect for as long as

                                       17

<PAGE>   18



     may be necessary to complete the distribution of the Securities; provided,
     however, that in connection therewith the Company shall not be required to

     Act or (B) the Option Closing Date, any event occurs as a result of which
     the Prospectus or any Integrated Prospectus, as then amended or
     supplemented, would include any untrue statement of a material fact or omit

     arbitrator applicable to any Selling Securityholder.

Such counsel shall also state that they have no reason to believe that the
Registration Statement, as of its effective date, contained any untrue statement
of a material fact or omitted to state any material fact required to be stated
therein or necessary to make the statements therein not misleading or that the
Prospectus or any Integrated Prospectus, as of their respective dates or the
date of such opinion, included or includes any untrue statement of a material
fact or omitted or omits to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

     In rendering any such opinion, such counsel may rely, as to matters of
fact, to the extent such counsel deems proper, on certificates of responsible
officers of the Company and public officials.

     References to the Registration Statement, the Prospectus and any Integrated
Prospectus in this paragraph (b) shall include any amendment or supplement
thereto at the date of such opinion.

     (c) The Representatives shall have received an opinion, dated the Firm
Closing Date, of Gibson, Dunn & Crutcher LLP, counsel for the Underwriters, with
respect to the issuance and sale of the Firm Securities, the Registration
Statement, the Prospectus and any Integrated Prospectus, and such other related
matters as the Representatives may reasonably require, and the Company and the
Selling Securityholders shall have furnished to such counsel such documents as
they may reasonably request for the purpose of enabling them to pass upon such
matters.

     (d) The Representatives shall have received from Deloitte & Touche LLP a
letter or letters dated, respectively, the date hereof and the Firm Closing
Date, in form and substance satisfactory to the Representatives, to the effect
that:

          (i) they are independent accountants with respect to the Company and
     its consolidated subsidiaries within the meaning of the Act, the Exchange
     Act and the applicable rules and regulations thereunder;

          (ii) in their opinion, the audited supplemental consolidated financial
     statements and schedules examined by them and included in the Registration
     Statement, the Prospectus and any Integrated Prospectus comply in form in
     all material respects with the applicable accounting requirements of the
     Act, the Exchange Act and the related published rules and regulations
     thereunder;

          (iii) on the basis of a reading of the latest available interim
     unaudited supplemental consolidated condensed financial statements of the
     Company and its consolidated subsidiaries, carrying out certain specified
     procedures (which do not constitute an examination made in accordance with
     generally accepted auditing standards) that would not necessarily reveal
     matters of significance with respect to the comments set forth in this
     paragraph (iii), a reading of the minute books of the shareholders, the
     board of directors and any committees thereof of the Company and each of
     its consolidated subsidiaries, and inquiries of certain officials of the
     Company and its consolidated

                                       25

<PAGE>   26


     subsidiaries who have responsibility for financial and accounting matters,
     nothing came to their attention that caused them to believe that:

               (A) the unaudited supplemental consolidated condensed financial
          statements of the Company and its consolidated subsidiaries included
          in the Registration Statement, the Prospectus and any Integrated
          Prospectus do not comply in form in all material respects with the
          applicable accounting requirements of the Act, the Exchange Act and
          the related published rules and regulations thereunder, or are not in
          conformity with generally accepted accounting principles applied on a
          basis substantially consistent with that of the audited supplemental
          consolidated financial statements included in the Registration
          Statement, the Prospectus and any Integrated Prospectus, or

               (B) at a specific date not more than five business days prior to
          the date of such letter, there were any changes in the capital stock
          or long-term debt of the Company and its consolidated subsidiaries or
          any decreases in net current assets or stockholders' equity of the
          Company and its consolidated subsidiaries, in each case compared with
          amounts shown on the unaudited March 31, 1996 supplemental
          consolidated balance sheet included in the Registration Statement, the
          Prospectus and any Integrated Prospectus, or for the period from April
          1, 1996 to such specified date there were any decreases, as compared
          with the corresponding period beginning April 1, 1995, in sales, net
          revenues, net income before income taxes or total or per share amounts
          of net income of the Company and its consolidated subsidiaries, except
          in all instances for changes, decreases or increases set forth in such
          letter; and

          (iv) they have carried out certain specified procedures, not
     constituting an audit, with respect to certain amounts, percentages and
     financial information that are derived from the general accounting records
     of the Company and its consolidated subsidiaries and are included in the
     Registration Statement, the Prospectus and any Integrated Prospectus, in
     Exhibit II to the Registration Statement and in the Exchange Act reports
     incorporated by reference in the Registration Statement, the Prospectus and
     any Integrated Prospectus, and have compared such amounts, percentages and
     financial information with such records of the Company and its consolidated
     subsidiaries and with information derived from such records and have found
     them to be in agreement, excluding any questions of legal interpretation.

     In the event that the letters referred to above set forth any such changes,
decreases or increases, it shall be a further condition to the obligations of
the Underwriters that (A) such letters shall be accompanied by a written
explanation of the Company as to the significance thereof, unless the
Representatives deem such explanation unnecessary, and (B) such changes,
decreases or increases do not, in the sole judgment of the Representatives, make
it impractical or inadvisable to proceed with the purchase and delivery of the
Securities as contemplated by the Registration Statement, as amended as of the
date hereof.

     References to the Registration Statement, the Prospectus and any Integrated
Prospectus in this paragraph (d) with respect to either letter referred to above

     (e) The Representatives shall have received a certificate, dated the Firm
Closing Date, of Eric R. Giler and Robert C. Leahy in their capacities as the
principal executive officer and the principal financial or accounting officer,
respectively, of the Company to the effect that:

          (i) the representations and warranties of the Company in this
     Agreement are true and correct as if made on and as of the Firm Closing
     Date; the Registration Statement, as amended as of the Firm Closing Date,
     does not include any untrue statement of a material fact or omit to state
     any material fact necessary to make the statements therein not misleading,
     the Prospectus and any Integrated Prospectus, as amended or supplemented as
     of the Firm Closing Date, do not include any untrue statement of a material
     fact or omit to state any material fact necessary in order to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading; and the Company has performed all covenants and
     agreements and satisfied all conditions on its part to be performed or
     satisfied at or prior to the Firm Closing Date;

          (ii) no stop order suspending the effectiveness of the Registration
     Statement or any post-effective amendment thereto and no order directed at
     any document incorporated by reference in the Registration Statement or the
     Prospectus or any amendment or supplement thereto has been issued, and no
     proceedings for that purpose have been instituted or threatened or, to the
     best of the Company's knowledge, are contemplated by the Commission; and

          (iii) subsequent to the respective dates as of which information is
     given in the Registration Statement, the Prospectus and any Integrated
     Prospectus, neither the Company nor any of its subsidiaries has sustained
     any material loss or interference with their respective businesses or
     properties from fire, flood, hurricane, accident or other calamity, whether
     or not covered by insurance, or from any labor dispute or any legal or
     governmental proceeding, and there has not been any material adverse
     change, or any development involving a prospective material adverse change,
     in the condition (financial or otherwise), management, business prospects,
     net worth or results of operations of the Company or any of its
     subsidiaries, except in each case as described in or contemplated by the
     Prospectus or any Integrated Prospectus.

     (f) The Representatives shall have received a certificate, dated the
Closing Date, from the Attorney-in-Fact on behalf of each Selling
Securityholder, to the effect that:

          (i) the representations and warranties of such Selling Securityholder
     in this Agreement are true and correct as if made on and as of the Closing
     Date;

          (ii) such Selling Securityholder has performed all covenants and
     agreements on its part to be performed or satisfied at or prior to the

                                       27
<PAGE>   28


          (iii) such Selling Securityholder has reviewed the Prospectus and any
     Integrated Prospectus (or, if the Prospectus and any required Integrated
     Prospectus is not in existence, the most recent Preliminary Prospectus) and
     the Registration Statement, and the information regarding such Selling
     Securityholder set forth therein under the caption "Principal and Selling
     Stockholders" is complete and accurate.

     (g) The Representatives shall have received from each person who is a
director or officer of the Company an agreement to the effect that such person
will not, directly or indirectly, without the prior written consent of
Prudential Securities Incorporated, on behalf of the Underwriters, offer, sell,
offer to sell, contract to sell, grant any option to purchase or otherwise sell
or dispose (or announce any offer, sale, offer of sale, contract of sale grant
of an option to purchase or other sale or disposition) of any shares of Common
Stock or any securities convertible into, or exchangeable or exercisable for,
shares of Common Stock for a period of 120 days after the date of this
Agreement.

     (h) On or before the Firm Closing Date, the Representatives and counsel for
the Underwriters shall have received such further certificates, documents or
other information as they may have reasonably requested from the Company.

     (i) Prior to the commencement of the offering of the Securities, the
Securities shall have been included for trading on the Nasdaq National Market.

     All opinions, certificates, letters and documents delivered pursuant to
this Agreement will comply with the provisions hereof only if they are
reasonably satisfactory in all material respects to the Representatives and
counsel for the Underwriters. The Company shall furnish to the Representatives
such conformed copies of such opinions, certificates, letters and documents in
such quantities as the Representatives and counsel for the Underwriters shall
reasonably request.

     The respective obligations of the several Underwriters to purchase and pay
for any Option Securities shall be subject, in their discretion, to each of the
foregoing conditions to purchase the Firm Securities, except that all references
to the Firm Securities and the Firm Closing Date shall be deemed to refer to
such Option Securities and the related Option Closing Date, respectively.

     8. INDEMNIFICATION AND CONTRIBUTION.

     (a) The Company and each of the Selling Securityholders, jointly and
severally (subject to the provisos in this Section 8(a) and in Sections 8(e),
8(f) and 8(g) hereof), agree to indemnify and hold harmless each Underwriter and
each person, if any, who controls any Underwriter within the meaning of Section
15 of the Act or Section 20 of the Exchange Act against any losses, claims,
damages or liabilities, joint or several, to which such Underwriter or such
controlling person may become subject under the Act, the Exchange Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon:

                                       28

<PAGE>   29


          (i) any untrue statement or alleged untrue statement made by the
     Company or any of the Selling Securityholders in either of Section 2(a) or
     Section 2(b) of this Agreement,

          (ii) any untrue statement or alleged untrue statement of any material
     fact contained in (A) the Registration Statement or any amendment thereto,
     any Preliminary Prospectus, the Prospectus or any Integrated Prospectus or
     any amendment or supplement thereto or (B) any application or other
     document, or any amendment or supplement thereto, executed by the Company
     or any Selling Securityholder or based upon written information furnished
     by or on behalf of the Company or any Selling Securityholder filed in any
     jurisdiction in order to qualify the Securities under the securities or
     blue sky laws thereof or filed with the Commission or any securities
     association or securities exchange (each an "Application"),

          (iii) the omission or alleged omission to state in the Registration
     Statement or any amendment thereto, any Preliminary Prospectus, the
     Prospectus or any Integrated Prospectus or any amendment or supplement
     thereto, or any Application a material fact required to be stated therein
     or necessary to make the statements therein not misleading, or

          (iv) any untrue statement or alleged untrue statement of any material
     fact contained in any audio or visual materials used in connection with the
     marketing of the Securities, including without limitation, slides, videos,
     films, tape recordings,

and will reimburse, as incurred, each Underwriter and each such controlling
person for any legal or other expenses reasonably incurred by such Underwriter
or such controlling person in connection with investigating, defending against
or appearing as a third-party witness in connection with any such loss, claim,
damage, liability or action; PROVIDED, HOWEVER, that the Company and the Selling
Securityholders will not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in
such registration statement or any amendment thereto, any Preliminary
Prospectus, the Prospectus or any Integrated Prospectus or any amendment or
supplement thereto, or any Application in reliance upon and in conformity with
written information furnished to the Company by such Underwriter through the
Representatives specifically for use therein. This indemnity agreement will be
in addition to any liability which the Company and the Selling Securityholders
may otherwise have. Neither the Company nor any Selling Securityholder will,
without the prior written consent of the Underwriter or Underwriters purchasing,
in the aggregate, more than fifty percent (50%) of the Securities, settle or
compromise or consent to the entry of any judgment in any pending or threatened
claim, action, suit or proceeding in respect of which indemnification may be
sought hereunder (whether or not any such Underwriter or any person who controls
any such Underwriter within the meaning of Section 15 of the Act or Section 20
of the Exchange Act is a party to such claim, action, suit or proceeding),
unless such settlement, compromise or consent includes an unconditional release
of all of the Underwriters and such controlling persons from all liability
arising out of such claim, action, suit or proceeding.

                                       29
<PAGE>   30


     (b) Each Underwriter will, severally and not jointly, indemnify and hold
harmless the Company, each of its directors, each of its officers who signed the
Registration Statement, the Selling Securityholders and each person, if any, who
controls the Company within the meaning of Section 15 of the Act or Section 20
of the Exchange Act against any losses, claims, damages or liabilities to which
the Company, the Selling Securityholders or any such director, officer or
controlling person of the Company may become subject under the Act, the Exchange
Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon (i) any untrue
statement or alleged untrue statement of any material fact contained in the
Registration Statement or any amendment thereto, any Preliminary Prospectus, the
Prospectus or any Integrated Prospectus or any amendment or supplement thereto,
or any Application or (ii) the omission or the alleged omission to state therein
a material fact required to be stated in the Registration Statement or any
amendment thereto, any Preliminary Prospectus, the Prospectus or any Integrated
Prospectus or any amendment or supplement thereto, or any Application or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with written information furnished to the Company by any Underwriter
through the Representatives specifically for use therein; and, subject to the
limitation set forth immediately preceding this clause, will reimburse, as
incurred, any legal or other expenses reasonably incurred by the Company, the
Selling Securityholders or any such director, officer or controlling person of
the Company in connection with investigating or defending any such loss, claim,
damage, liability or any action in respect thereof. This indemnity agreement
will be in addition to any liability which such Underwriter may otherwise have.

     (c) Promptly after receipt by an indemnified party under this Section 8 of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party of the commencement thereof; but the
omission so to notify the indemnifying party will not relieve it from any
liability which it may have to any indemnified party except to the extent that
the indemnifying party is prejudiced as a result thereof. In case any such
action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party; PROVIDED, HOWEVER,
that if the defendants in any such action include both the indemnified party and
the indemnifying party and the indemnified party shall have reasonably concluded
that there may be one or more legal defenses available to it and/or other
indemnified parties which are different from or additional to those available to
the indemnifying party, the indemnifying party shall not have the right to
direct the defense of such action on behalf of such indemnified party or parties
and such indemnified party or parties shall have the right to select separate
counsel to defend such action on behalf of such indemnified party or parties.
After notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof and approval by such indemnified party
of counsel appointed to defend such action, the indemnifying party will not be
liable to such indemnified party under this Section 8 for any legal or other
expenses, other than reasonable costs of investigation, subsequently incurred by
such indemnified party in connection with the defense thereof, unless (i)


                                       30
<PAGE>   31


the indemnified party shall have employed separate counsel in accordance with
the proviso to the next preceding sentence (it being understood, however, that
in connection with such action the indemnifying party shall not be liable for
the expenses of more than one separate counsel (in addition to local counsel) in
any one action or separate but substantially similar actions in the same
jurisdiction arising out of the same general allegations or circumstances,
designated by the Representatives in the case of paragraph (a) of this Section
8, representing the indemnified parties under such paragraph (a) who are parties
to such action or actions) or (ii) the indemnifying party does not promptly
retain counsel reasonably satisfactory to the indemnified party (it being
understood that Goodwin, Procter & Hoar LLP shall be deemed reasonably
satisfactory as counsel to be retained by the Company and/or the Selling
Securityholders in any case) or (iii) the indemnifying party has authorized the
employment of counsel for the indemnified party at the expense of the
indemnifying party. After such notice from the indemnifying party to such
indemnified party, the indemnifying party will not be liable for the costs and
expenses of any settlement of such action effected by such indemnified party
without the consent of the indemnifying party.

     (d) In circumstances in which the indemnity agreement provided for in the
preceding paragraphs of this Section 8 is unavailable or insufficient, for any
reason, to hold harmless an indemnified party in respect of any losses, claims,
damages or liabilities (or actions in respect thereof), each indemnifying party,
in order to provide for just and equitable contribution, shall contribute to the
amount paid or payable by such indemnified party as a result of such losses,
claims, damages or liabilities (or actions in respect thereof) in such
proportion as is appropriate to reflect (i) the relative benefits received by
the indemnifying party or parties on the one hand and the indemnified party on
the other from the offering of the Securities or (ii) if the allocation provided
by the foregoing clause (i) is not permitted by applicable law, not only such
relative benefits but also the relative fault of the indemnifying party or
parties on the one hand and the indemnified party on the other in connection
with the statements or omissions or alleged statements or omissions that
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations. The relative
benefits received by the Company and the Selling Securityholders on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total proceeds from the offering (before deducting expenses) received by
the Company and the Selling Securityholders bear to the total underwriting
discounts and commissions received by the Underwriters. The relative fault of
the parties shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the
Company, the Selling Securityholders or the Underwriters, the parties' relative
intents, knowledge, access to information and opportunity to correct or prevent
such statement or omission, and any other equitable considerations appropriate
in the circumstances. The Company, the Selling Securityholders and the
Underwriters agree that it would not be equitable if the amount of such
contribution were determined by pro rata or per capita allocation (even if the
Underwriters were treated as one entity for such purpose) or by any other method
of allocation that does not take into account the equitable considerations
referred to above in this paragraph (d). Notwithstanding any other provision of
this paragraph (d), no Underwriter shall be obligated to make contributions
hereunder that in the aggregate exceed the total public offering price of the
Securities purchased by such Underwriter under this Agreement,

                                       31
<PAGE>   32



less the aggregate amount of any damages that such Underwriter has otherwise
been required to pay in respect of the same or any substantially similar claim,
and 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 hereunder are several in proportion to their
respective underwriting obligations and not joint, and contributions among
Underwriters shall be governed by the provisions of the Prudential Securities
Incorporated Master Agreement Among Underwriters. For purposes of this paragraph
(d), each person, if any, who controls an Underwriter within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act shall have the same
rights to contribution as such Underwriter, and each director of the Company,
each officer of the Company who signed the Registration Statement and each
person, if any, who controls the Company within the meaning of Section 15 of the
Act or Section 20 of the Exchange Act, shall have the same rights to
contribution as the Company.

     (e) A Selling Securityholder's liability for any claim under this Agreement
(except to the extent that such claim is based upon an untrue statement or
alleged untrue statement made by any Selling Securityholder in any of Sections
2(b)(i) through Sections 2(b)(ix), for which this limitation shall not apply)
shall not exceed such Selling Securityholder's "pro rata share" of the total
amount of the Underwriters' losses, claims, damages or liabilities and related
expenses including attorney's fees for which the Company and the Selling
Securityholders are liable under this Agreement, with respect to the facts,
circumstances, transaction or occurrence giving rise to such claim; with "pro
rata share" defined as that fraction which is equal to the number of Securities
sold by such Selling Securityholder in the offering divided by the aggregate
number of Securities sold by the Company and all Selling Securityholders in the
offering;

     (f) No Underwriter or controlling person may obtain any remedies from any
Selling Securityholder for any specific claim under this Agreement (except for
any claim based upon an untrue statement or alleged untrue statement made by any
Selling Securityholder in any of Sections 2(b)(i) through Sections 2(b)(ix) to
which this restriction shall not apply), until such Underwriter or controlling
person has first used its best efforts to pursue and exhaust all remedies
(including the enforcement and collection of judgments or claims against the
Company) it may have against the Company with respect to such specific claim.
Without limiting the generality of the foregoing, an Underwriter or controlling
person shall be deemed to have used its best efforts to pursue and exhaust all
remedies it may have against the Company with respect to such specific claim,
and may pursue any remedies it may have against the Selling Securityholder, if
(A) such Underwriter or controlling person is in the process of pursuing
remedies against the Company and any of the following events occurs, or,
immediately prior to the time at which such Underwriter or controlling person
commences the process of pursuing remedies against the Company, any of the
following events has occurred and is continuing: (1) the Company files a
petition, answer or any pleading seeking or acquiescing in any reorganization,
liquidation or other relief under chapter 7 or 11 of the Bankruptcy Code; (2)
the Company seeks or acquiesces in the appointment of a trustee (other than a
trustee appointed solely for the purposes of facilitating the issuance of any
debt securities of the Company), receiver or liquidator of all or part of its
assets; or (3) the Company makes a general assignment for the benefit of its
creditors, (B) a court of competent jurisdiction: (1) appoints a trustee,
receiver or liquidator of all or part of the Company's assets; or (2) determines
in any action, suit or proceeding that the Company is insolvent (in the
accounting,

                                       32

<PAGE>   33


bankruptcy, equity or legal definitions), or (C) a court or arbitration panel of
competent jurisdiction enters an order in any such action, suit or proceeding by
such Underwriter or controlling person against the Company that is adverse to
such Underwriter or controlling person. Notwithstanding the foregoing, if, in
the reasonable judgment of any Underwriter or controlling person, the applicable
statute of limitations for any potential action, suit or proceeding by such
Underwriter or controlling person for indemnification against the Selling
Securityholder will expire, such Underwriter or controlling person may name the
Selling Securityholder in any action, suit or proceeding to which the Company is
also a party solely for purposes of preserving any rights such Underwriter or
controlling person may have to seek indemnification from the Selling
Securityholder after having used its best efforts to pursue and exhaust all
remedies it may have against the Company.

     (g) The aggregate liability of each Selling Securityholder under all
provisions of this Agreement shall not exceed the amount equal to the aggregate
proceeds received by such Selling Securityholder for the Securities sold by such
Selling Securityholder to the Underwriters.

     9. DEFAULT OF UNDERWRITERS. If one or more Underwriters default in their
obligations to purchase Firm Securities or Option Securities hereunder and the
aggregate number of such Securities that such defaulting Underwriter or
Underwriters agreed but failed to purchase is ten percent or less of the
aggregate number of Firm Securities or Option Securities to be purchased by all
of the Underwriters at such time hereunder, the other Underwriters may make
arrangements satisfactory to the Representatives for the purchase of such
Securities by other persons (who may include one or more of the non-defaulting
Underwriters, including the Representatives), but if no such arrangements are
made by the Firm Closing Date or the related Option Closing Date, as the case
may be, the other Underwriters shall be obligated severally in proportion to
their respective commitments hereunder to purchase the Firm Securities or Option
Securities that such defaulting Underwriter or Underwriters agreed but failed to
purchase. If one or more Underwriters so default with respect to an aggregate
number of Securities that is more than ten percent of the aggregate number of
Firm Securities or Option Securities, as the case may be, to be purchased by all
of the Underwriters at such time hereunder, and if arrangements satisfactory to
the Representatives are not made within 36 hours after such default for the
purchase by other persons (who may include one or more of the non-defaulting
Underwriters, including the Representatives) of the Securities with respect to
which such default occurs, this Agreement will terminate without liability on
the part of any non-defaulting Underwriter or the Company other than as provided
in Section 10 hereof. In the event of any default by one or more Underwriters as
described in this Section 9, the Representatives shall have the right to
postpone the Firm Closing Date or the Option Closing Date, as the case may be,
established as provided in Section 3 hereof for not more than seven business
days in order that any necessary changes may be made in the arrangements or
documents for the purchase and delivery of the Firm Securities or Option
Securities, as the case may be. As used in this Agreement, the term
"Underwriter" includes any person substituted for an Underwriter under this
Section 9. Nothing herein shall relieve any defaulting Underwriter from
liability for its default.

     10. SURVIVAL. The respective representations, warranties, agreements,
covenants, indemnities and other statements of the Company, its officers, the
Selling Securityholders and the several Underwriters set forth in this Agreement
or made by or on behalf

                                       33

<PAGE>   34


of them, respectively, pursuant to this Agreement shall remain in full force and
effect, regardless of (i) any investigation made by or on behalf of the Company,
any of its officers or directors, any Underwriter or any controlling person
referred to in Section 8 hereof and (ii) delivery of and payment for the
Securities. The respective agreements, covenants, indemnities and other
statements set forth in Sections 6 and 8 hereof shall remain in full force and
effect, regardless of any termination or cancellation of this Agreement.

     11. TERMINATION.

     (a) This Agreement may be terminated with respect to the Firm Securities or
any Option Securities in the sole discretion of the Representatives by notice to
the Company given prior to the Firm Closing Date or the related Option Closing
Date, respectively, in the event that the Company or any Selling Securityholder
shall have failed, refused or been unable to perform all obligations and satisfy
all conditions on its or their respective part to be performed or satisfied
hereunder at or prior thereto or, if at or prior to the Firm Closing Date or
such Option Closing Date, respectively,

          (i) the Company or any of its subsidiaries shall have, in the sole
     judgment of the Representatives, sustained any material loss or
     interference with their respective businesses or properties from fire,
     flood, hurricane, accident or other calamity, whether or not covered by
     insurance, or from any labor dispute or any legal or governmental
     proceeding or there shall have been any material adverse change, or any
     development involving a prospective material adverse change (including
     without limitation a change in management or control of the Company), in
     the condition (financial or otherwise), business prospects, net worth or
     results of operations of the Company and its subsidiaries, except in each
     case as described in or contemplated by the Prospectus (exclusive of any
     amendment or supplement thereto);

          (ii) trading in the Common Stock shall have been suspended by the
     Commission or the Nasdaq National Market or trading in securities generally
     on the New York Stock Exchange or the Nasdaq National Market shall have
     been suspended or minimum or maximum prices shall have been established on
     either such exchange or market system;

          (iii) a banking moratorium shall have been declared by Massachusetts,
     New York or United States authorities; or

          (iv) there shall have been (A) an outbreak or escalation of
     hostilities between the United States and any foreign power, (B) an
     outbreak or escalation of any other insurrection or armed conflict
     involving the United States or (C) any other calamity or crisis or material
     adverse change in general economic, political or financial conditions
     having an effect on the U. S. financial markets that, in the sole judgment
     of the Representatives, makes it impractical or inadvisable to proceed with
     the public offering or the delivery of the Securities as contemplated by
     the Registration Statement, as amended as of the date hereof.

                                       34

<PAGE>   35


     (b) Termination of this Agreement pursuant to this Section 11 shall be
without liability of any party to any other party except as provided in Section
10 hereof.

binding upon the several Underwriters, the Company, the Selling Securityholders
and their respective successors and legal representatives, and nothing expressed

other person any legal or equitable right, remedy or claim under or in respect

agree to be bound by any judgment rendered thereby in connection with this
Agreement. The Company designates and appoints _____________, and the Selling
Securityholders designate and appoint _____________ and such other persons as
may hereafter be selected by the Company or any Selling Securityholder
irrevocably agreeing in writing to so serve, as their respective agents to
receive on their behalf service of all process in any such proceedings in any

Selling Securityholders to be effective and binding service in every respect. A
copy of any such process so served shall be mailed by registered mail to Company

provided in Section 13 hereof; PROVIDED, HOWEVER, that, unless otherwise
provided by applicable law, any failure to mail such copy shall not affect the
validity of service of such process. If any agent appointed by the Company or

Selling Securityholders hereby agree that service of process sufficient for
personal jurisdiction in any action against the Company and any such Selling
Securityholder in the State of New York may be made by registered or certified
mail, return receipt requested, to the Company and/or any such Selling

13 hereof, and the Company and the Selling Securityholder hereby acknowledge
that such service shall be effective and binding in every respect. Nothing
herein shall affect the right to serve process in any other manner permitted by
law or shall limit the right of any Underwriter to bring proceedings against the
Company or the Selling Securityholders in the courts of any other jurisdiction.

     17. COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

Ladies and Gentlemen:

        Re:  Registration Statement on Form S-3
             ----------------------------------

        This opinion is delivered in our capacity as counsel to Brooktrout
Technology, Inc. (the "Company") in connection with the preparation and filing
with the Securities and Exchange Commission under the Securities Act of 1933,
as amended, of Amendment No. 1 to the Registration Statement on Form S-3 (the
"Registration Statement") relating to 2,250,000 shares of Common Stock, par
value $.01 per share (the "Registered Shares"), including 337,500 shares which
the underwriters have an option to purchase solely for the purpose of covering
over-allotments. Of the 2,250,000 Registered Shares, 1,445,029 are to be sold
by the Company (the "Primary Shares"), 804,971 are to be sold by certain Selling
Stockholders (the "Selling Stockholder Shares") and 337,500 may be sold by the 
Company pursuant to the over-allotment option (collectively with the Primary
Shares, the "Company Shares") to underwriters (the "Underwriters") of which
Prudential Securities Incorporated, Smith Barney Inc. and Tucker Anthony
Incorporated are the representatives (the "Representatives") pursuant to an
Underwriting Agreement (the "Underwriting Agreement") between the Company and
the Representatives of the Underwriters.

        As counsel for the Company, we have examined the form of the proposed
Underwriting Agreement being filed as an exhibit to the Registration Statement,
the Restated Articles of Organization and the Company's Amended and Restated
By-laws, each as presently in effect, and such records, certificates and other
documents of the Company as we have deemed necessary or appropriate for the
purposes of this opinion.

        We are attorneys admitted to practice in The Commonwealth of
Massachusetts and certain other jurisdictions. We express no opinion concerning
the laws of any jurisdictions other than the laws of the United States of
America and The Commonwealth of Massachusetts, and also express no opinion with
respect to the blue sky or securities laws of any state, including
Massachusetts.

        Based on the foregoing, we are of the opinion that (A) when the
Underwriting Agreement is completed (including the insertion therein of pricing
terms) and executed by the Company and on behalf of the Underwriters, and the
Company Shares are sold to the Underwriters and paid for pursuant to the terms
of the Underwriting Agreement, the Company Shares will be duly authorized,
legally issued, fully paid and non-assessable by the Company under the Business
Corporation Law of The Commonwealth of Massachusetts (the "MBCL"), and (B) the
Selling Stockholder Shares are duly authorized, legally issued, fully paid and 
non-assessable by the Company under the MBCL.

        We hereby consent to being named as counsel to the Company in the
Registration Statement, to the references therein to our firm under the caption
"Legal Matters," and to the inclusion of this opinion as an exhibit to the
Registration Statement.

                                        Very truly yours,

historical financial statements of Brooktrout Technology, Inc., and of our
report dated March 8, 1996 (which includes an explanatory paragraph relating to
the acquisition of TSI by Brooktrout Technology, Inc.), appearing in the Proxy
Statement for the Annual Meeting of Stockholders held on May 29, 1996 of
Brooktrout Technology, Inc., related to the historical financial statements of
