Ladies and Gentlemen:

         Versatility Inc., a Delaware corporation (the "Company"), and the
persons listed on Schedule B hereto (the "Selling Shareholders"), confirm their
respective agreements with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner &
Smith Incorporated ("Merrill Lynch"), Montgomery Securities ("Montgomery") and
Oppenheimer & Co., Inc. ("Oppenheimer") and each of the other Underwriters named
in Schedule A hereto (collectively, the "Underwriters," which term shall also
include any underwriter substituted as hereinafter provided in Section 10
hereof), for whom Merrill Lynch, Montgomery and Oppenheimer are acting as
representatives (in such capacity, the "Representatives"), with respect to (i)
the sale by the Company and the purchase by the
   2
Underwriters, acting severally and not jointly, of the respective numbers of
shares of Common Stock, par value $.01 per share, of the Company ("Common
Stock") set forth in Schedule A hereto and (ii) the grant by the Company and the
Selling Shareholders to the Underwriters, acting severally and not jointly, of
the option described in Section 2(b) hereof to purchase all or any part of
330,000 additional shares of Common Stock to cover over-allotments, if any. The
aforesaid 2,200,000 shares of Common Stock (the "Initial Securities") to be
purchased by the Underwriters and all or any part of the 330,000 shares of
Common Stock subject to the option described in Section 2(b) hereof (the "Option
Securities") are hereinafter called, collectively, the "Securities."

         The Company and the Selling Shareholders understand that the
Underwriters propose to make a public offering of the Securities as soon as the
Representatives deem advisable after this Agreement has been executed and
delivered.

         The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-1 (No. 333-___) covering the
registration of the Securities under the Securities Act of 1933, as amended (the
"1933 Act"), including the related preliminary prospectus or prospectuses.
Promptly after execution and delivery of this Agreement, the Company will either
(i) prepare and file a prospectus in accordance with the provisions of Rule 430A
("Rule 430A") of the rules and regulations of the Commission under the 1933 Act
(the "1933 Act Regulations") and paragraph (b) of Rule 424 ("Rule 424(b)") of
the 1933 Act Regulations or (ii) if the Company has elected to rely upon Rule
434 ("Rule 434") of the 1933 Act Regulations, prepare and file a term sheet (a
"Term Sheet") in accordance with the provisions of Rule 434 and Rule 424(b). The
information included in such prospectus or in such Term Sheet, as the case may
be, that was omitted from such registration statement at the time it became
effective, but that is deemed to be part of such registration statement at the
time it became effective (a) pursuant to paragraph (b) of Rule 430A is referred
to as "Rule 430A Information" or (b) pursuant to paragraph (d) of Rule 434 is
referred to as "Rule 434 Information." Each prospectus used before such
registration statement became effective, and any prospectus that omitted, as
applicable, the Rule 430A Information or the Rule 434 Information, that was used
after such effectiveness and prior to the execution and delivery
   3
of this Agreement, is herein called a "preliminary prospectus." Such
registration statement, including the exhibits thereto and schedules thereto at
the time it became effective and including the Rule 430A Information and the
Rule 434 Information, as applicable, is herein called the "Registration
Statement." Any registration statement filed pursuant to Rule 462(b) of the 1933
Act Regulations is herein referred to as the "Rule 462(b) Registration
Statement," and after such filing the term "Registration Statement" shall
include the Rule 462(b) Registration Statement. The final prospectus in the form
first furnished to the Underwriters for use in connection with the offering of
the Securities is herein called the "Prospectus." If Rule 434 is relied on, the
term "Prospectus" shall refer to the preliminary prospectus dated ____________,
1996 together with the Term Sheet and all references in this Agreement to the
date of the Prospectus shall mean the date of the Term Sheet. For purposes of
this Agreement, all references to the Registration Statement, any preliminary
prospectus, the Prospectus or any Term Sheet or any amendment or supplement to
any of the foregoing shall be deemed to include the copy filed with the
Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval
system ("EDGAR").

         SECTION 1.  Representations and Warranties.

         (a) Representations and Warranties by the Company. The Company
represents and warrants to each Underwriter as of the date hereof, as of the
Closing Time referred to in Section 2(c) hereof, and as of each Date of Delivery
(if any) referred to in Section 2(b) hereof, and agrees with each Underwriter,
as follows:

                   (i)     Compliance with Registration Requirements.  Each
         of the Registration Statement and any Rule 462(b)
         Registration Statement has become effective under the 1933
         Act and no stop order suspending the effectiveness of the
         Registration Statement or any Rule 462(b) Registration
         Statement has been issued under the 1933 Act and no
         proceedings for that purpose have been instituted or are
         pending or, to the knowledge of the Company, are
         contemplated by the Commission, and any request on the part
   4
         of the Commission for additional information has been
         complied with.

              At the respective times the Registration Statement, any Rule
         462(b) Registration Statement and any post-effective amendments thereto
         became effective and at the Closing Time (and, if any Option Securities
         are purchased, at the Date of Delivery), the Registration Statement,
         the Rule 462(b) Registration Statement and any amendments and
         supplements thereto complied and will comply in all material respects
         with the requirements of the 1933 Act and the 1933 Act Regulations and
         did not and will 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. Neither the
         Prospectus nor any amendments or supplements thereto, at the time the
         Prospectus or any such amendment or supplement was issued and at the
         Closing Time (and, if any Option Securities are purchased, at the Date
         of Delivery), included or will include an untrue statement of a
         material fact or omitted or will omit 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. If Rule 434
         is used, the Company will comply with the requirements of Rule 434 and
         the Prospectus shall not be "materially different," as such term is
         used in Rule 434, from the prospectus included in the Registration
         Statement at the time it became effective. The representations and
         warranties in this subsection shall not apply to statements in or
         omissions from the Registration Statement or Prospectus made in
         reliance upon and in conformity with information furnished to the
         Company in writing by any Underwriter through Merrill Lynch expressly
         for use in the Registration Statement or Prospectus.

              Each preliminary prospectus and the prospectus filed as part of
         the Registration Statement as originally filed or as part of any
         amendment thereto, or filed pursuant to Rule 424 under the 1933 Act,
         complied when so filed in all material respects with the 1933 Act
         Regulations and each preliminary prospectus and the Prospectus
         delivered to the Underwriters for use in connection with this offering
         was identical to the electronically transmitted copies thereof filed
         with the
   5
         Commission pursuant to EDGAR, except to the extent permitted by
         Regulation S-T.

                  (ii) Independent Accountants. The accountants who certified
         the financial statements and supporting schedules included in the
         Registration Statement are independent public accountants as required
         by the 1933 Act and the 1933 Act Regulations.

                 (iii) Financial Statements. The financial statements included
         in the Registration Statement and the Prospectus, together with the
         related schedules and notes, present fairly the financial position of
         the Company and its consolidated subsidiaries at the dates indicated
         and the statement of operations, stockholders' equity and cash flows of
         the Company and its consolidated subsidiaries for the periods
         specified; said financial statements have been prepared in conformity
         with generally accepted accounting principles ("GAAP") applied on a
         consistent basis throughout the periods involved. The supporting
         schedules included in the Registration Statement present fairly in
         accordance with GAAP the information required to be stated therein. The
         selected financial data and the summary financial information included
         in the Prospectus present fairly the information shown therein and have
         been compiled on a basis consistent with that of the audited financial
         statements included in the Registration Statement.

                  (iv) No Material Adverse Change in Business. Since the
         respective dates as of which information is given in the Registration
         Statement and the Prospectus, except as otherwise stated therein, (A)
         there has been no material adverse change in the condition, financial
         or otherwise, or in the earnings, business affairs or business
         prospects of the Company and its subsidiaries considered as one
         enterprise, whether or not arising in the ordinary course of business
         (a "Material Adverse Effect"), (B) there have been no transactions
         entered into by the Company or any of its subsidiaries, other than
         those in the ordinary course of business, which are material with
         respect to the Company and its subsidiaries considered as one
         enterprise, and (C) there has been no dividend or distribution of any
         kind declared,
   6
         paid or made by the Company on any class of its capital
         stock.

                   (v) Good Standing of the Company. The Company has been duly
         organized and is validly existing as a corporation in good standing
         under the laws of the State of Delaware and has corporate power and
         authority to own, lease and operate its properties and to conduct its
         business as described in the Prospectus and to enter into and perform
         its obligations under this Agreement; and the Company is duly qualified
         as a foreign corporation to transact business and is in good standing
         in each other jurisdiction in which such qualification is required,
         whether by reason of the ownership or leasing of property or the
         conduct of business, except where the failure so to qualify or to be in
         good standing would not result in a Material Adverse Effect.

                  (vi) Good Standing of Subsidiaries. Each "significant
         subsidiary" of the Company (as such term is defined in Rule 1-02 of
         Regulation S-X) (each a "Subsidiary" and, collectively, the
         "Subsidiaries") is listed on Exhibit 21.1 to the Registration Statement
         and has been duly organized and is validly existing as a corporation in
         good standing under the laws of the jurisdiction of its incorporation,
         has corporate power and authority to own, lease and operate its
         properties and to conduct its business as described in the Prospectus
         and is duly qualified as a foreign corporation to transact business and
         is in good standing in each jurisdiction in which such qualification is
         required, whether by reason of the ownership or leasing of property or
         the conduct of business, except where the failure so to qualify or to
         be in good standing would not result in a Material Adverse Effect;
         except as otherwise disclosed in the Registration Statement, all of the
         issued and outstanding capital stock of each such Subsidiary has been
         duly authorized and validly issued, is fully paid and non-assessable
         and is owned by the Company, directly or through subsidiaries, free and
         clear of any security interest, mortgage, pledge, lien, encumbrance,
         claim or equity (except that the Company has pledged its shares of
         stock in each Subsidiary to Silicon Valley Bank to secure the line of
         credit described in the Prospectus); none of the outstanding shares of
         capital stock of any Subsidiary was issued in violation of the
         preemptive or similar rights of
   7
         any security holder of such Subsidiary. The only subsidiaries of the
         Company are the subsidiaries listed on Exhibit 21.1 to the Registration
         Statement.

                 (vii) Capitalization. The authorized, issued and outstanding
         capital stock of the Company is set forth in the Prospectus in the
         column entitled "Actual" under the caption "Capitalization" (except for
         subsequent issuances, if any, pursuant to this Agreement, pursuant to
         reservations, agreements or employee benefit plans referred to in the
         Prospectus or pursuant to the exercise of convertible securities or
         options referred to in the Prospectus). The shares of issued and
         outstanding capital stock, including the Securities to be purchased by
         the Underwriters from the Selling Shareholders, have been duly
         authorized and validly issued and are fully paid and non-assessable;
         none of the outstanding shares of capital stock, including the
         Securities to be purchased by the Underwriters from the Selling
         Shareholders, was issued in violation of the preemptive or other
         similar rights of any securityholder of the Company.

                  (viii) Authorization of Agreement. This Agreement has been
         duly authorized, executed and delivered by the Company.

                  (ix) Authorization and Description of Securities. The
         Securities to be purchased by the Underwriters from the Company have
         been duly authorized for issuance and sale to the Underwriters pursuant
         to this Agreement and, when issued and delivered by the Company
         pursuant to this Agreement against payment of the consideration set
         forth herein, will be validly issued and fully paid and non-assessable;
         the Common Stock conforms to all statements relating thereto contained
         in the Prospectus and such description conforms to the rights set forth
         in the instruments defining the same; no holder of the Securities will
         be subject to personal liability by reason of being such a holder; and
         the issuance of the Securities is not subject to the preemptive or
         other similar rights of any securityholder of the Company.

                  (x) Absence of Defaults and Conflicts. Neither the Company nor
         any of its Subsidiaries is in violation of its
   8
         charter or by-laws or in default in the performance or observance of
         any obligation, agreement, covenant or condition contained in any
         contract, indenture, mortgage, deed of trust, loan or credit agreement,
         note, lease or other agreement or instrument to which the Company or
         any of its Subsidiaries is a party or by which it or any of them may be
         bound, or to which any of the property or assets of the Company or any
         Subsidiary is subject (collectively, "Agreements and Instruments")
         except for such defaults that would not result in a Material Adverse
         Effect; and the execution, delivery and performance of this Agreement
         and the consummation of the transactions contemplated herein and in the
         Registration Statement (including the issuance and sale of the
         Securities and the use of the proceeds from the sale of the Securities
         as described in the Prospectus under the caption "Use of Proceeds") and
         compliance by the Company with its obligations hereunder have been duly
         authorized by all necessary corporate action and do not and will not,
         whether with or without the giving of notice or passage of time or
         both, conflict with or constitute a breach of, or default or Repayment
         Event (as defined below) under, or result in the creation or imposition
         of any lien, charge or encumbrance upon any property or assets of the
         Company or any subsidiary pursuant to, the Agreements and Instruments
         (except for such conflicts, breaches or defaults or liens, charges or
         encumbrances that would not result in a Material Adverse Effect), nor
         will such action result in any violation of the provisions of the
         charter or by-laws of the Company or any subsidiary or any applicable
         law, statute, rule, regulation, judgment, order, writ or decree of any
         government, government instrumentality or court, domestic or foreign,
         having jurisdiction over the Company or any Subsidiary or any of their
         assets, properties or operations.
          As used herein, a "Repayment Event" means any event or condition which
         gives the holder of any note, debenture or other evidence of
         indebtedness (or any person acting on such holder's behalf) the right
         to require the repurchase, redemption or repayment of all or a portion
         of such indebtedness by the Company or any Subsidiary.

                  (xi)     Absence of Labor Dispute.  No labor dispute with
         the employees of the Company or any Subsidiary exists or, to
         the knowledge of the Company, is imminent, and the Company
         is not aware of any existing or imminent labor disturbance
   9
         by the employees of any of its or any Subsidiary's principal suppliers,
         manufacturers, customers or contractors, which, in either case, may
         reasonably be expected to result in a Material Adverse Effect.

                 (xii) Absence of Proceedings. There is no action, suit,
         proceeding, inquiry or investigation before or brought by any court or
         governmental agency or body, domestic or foreign, now pending, or, to
         the knowledge of the Company, threatened, against or affecting the
         Company or any Subsidiary, which is required to be disclosed in the
         Registration Statement (other than as disclosed therein), or which
         might reasonably be expected to result in a Material Adverse Effect, or
         which might reasonably be expected to materially and adversely affect
         the properties or assets thereof or the consummation of the
         transactions contemplated in this Agreement or the performance by the
         Company of its obligations hereunder; the aggregate of all pending
         legal or governmental proceedings to which the Company or any
         Subsidiary is a party or of which any of their respective property or
         assets is the subject which are not described in the Registration
         Statement, including ordinary routine litigation incidental to the
         business, could not reasonably be expected to result in a Material
         Adverse Effect.

                (xiii) Accuracy of Exhibits. There are no contracts or documents
         which are required to be described in the Registration Statement or the
         Prospectus or to be filed as exhibits thereto which have not been so
         described and filed as required.

                 (xiv) Possession of Intellectual Property. The Company and its
         Subsidiaries own or possess, or can acquire on reasonable terms,
         adequate patents, patent rights, licenses, inventions, copyrights,
         know-how (including trade secrets and other unpatented and/or
         unpatentable proprietary or confidential information, systems or
         procedures), trademarks, service marks, trade names or other
         intellectual property (collectively, "Intellectual Property") necessary
         to carry on the business now operated by them, and neither the Company
         nor any of its Subsidiaries has received any notice or is otherwise
         aware of any infringement of or
   10
         conflict with asserted rights of others with respect to any
         Intellectual Property or of any facts or circumstances which would
         render any Intellectual Property invalid or inadequate to protect the
         interest of the Company or any of its Subsidiaries therein, and which
         infringement or conflict (if the subject of any unfavorable decision,
         ruling or funding) or invalidity or inadequacy, singly or in the
         aggregate, would result in a Material Adverse Effect.

                  (xv) Absence of Further Requirements. No filing with, or
         authorization, approval, consent, license, order, registration,
         qualification or decree of, any court or governmental authority or
         agency is necessary or required for the performance by the Company of
         its obligations hereunder, in connection with the offering, issuance or
         sale of the Securities hereunder or the consummation of the
         transactions contemplated by this Agreement, except such as have been
         already obtained or as may be required under the 1933 Act or the 1933
         Act Regulations, state securities laws or the rules and regulations of
         the National Association of Securities Dealers, Inc.

                 (xvi) Possession of Licenses and Permits. The Company and its
         Subsidiaries possess such permits, licenses, approvals, consents and
         other authorizations (collectively, "Governmental Licenses") issued by
         the appropriate federal, state, local or foreign regulatory agencies or
         bodies necessary to conduct the business now operated by them, except
         where the failure to possess such Governmental License would not,
         singly or in the aggregate, have a Material Adverse Effect; the Company
         and its Subsidiaries are in compliance with the terms and conditions of
         all such Governmental Licenses, except where the failure so to comply
         would not, singly or in the aggregate, have a Material Adverse Effect;
         all of the Governmental Licenses are valid and in full force and
         effect, except when the invalidity of such Governmental Licenses or the
         failure of such Governmental Licenses to be in full force and effect
         would not have a Material Adverse Effect; and neither the Company nor
         any of its Subsidiaries has received any notice of proceedings relating
         to the revocation or modification of any such Governmental Licenses
         which, singly or in the aggregate, if the subject of an unfavorable
         decision, ruling or funding, would result in a Material Adverse Effect.
   11
                (xvii) Title to Property. Neither the Company nor any of its
         Subsidiaries owns any real property; and all of the leases and
         subleases material to the business of the Company and its Subsidiaries,
         considered as one enterprise, and under which the Company or any of its
         Subsidiaries holds properties described in the Prospectus, are in full
         force and effect, and neither the Company nor any Subsidiary has any
         notice of any material claim of any sort that has been asserted by
         anyone adverse to the rights of the Company or any Subsidiary under any
         of the leases or subleases mentioned above, or affecting or questioning
         the rights of the Company or such Subsidiary to the continued
         possession of the leased or subleased premises under any such lease or
         sublease.

               (xviii) Compliance with Cuba Act. The Company has complied with,
         and is and will be in compliance with, the provisions of that certain
         Florida act relating to disclosure of doing business with Cuba,
         codified as Section 517.075 of the Florida statutes, and the rules and
         regulations thereunder (collectively, the "Cuba Act") or is exempt
         therefrom.

                 (xix) Investment Company Act. The Company is not, and upon the
         issuance and sale of the Securities as herein contemplated and the
         application of the net proceeds therefrom as described in the

                  (xx) Environmental Laws. Except as described in the
         Registration Statement and except as would not, singly or in the
         aggregate, result in a Material Adverse Effect, (A) neither the Company
         nor any of its Subsidiaries is in violation of any federal, state,
         local or foreign statute, law, rule, regulation, ordinance, code,

         governmental body or agency, against or affecting the Company or any of
         its Subsidiaries relating to Hazardous Materials or any Environmental
         Laws.

                 (xxi) Registration Rights. There are no persons with
         registration rights or other similar rights, which have not been
         satisfied or waived, to have any securities registered pursuant to the
         Registration Statement or otherwise registered by the Company under the
         1933 Act.

                   (b) Representations and Warranties by the Selling
Shareholders. Each Selling Shareholder, severally, represents and warrants to
each Underwriter as of the date hereof, as of the Closing Time, and, if such
Selling Shareholder is selling Option Securities on a Date of Delivery, as of
each such Date of Delivery, and agrees with each Underwriter, as follows:

                   (i) Accurate Disclosure. To the best knowledge of such
         Selling Shareholder, the representations and warranties of the Company
         contained in Section 1(a) hereof are true and correct; such Selling
         Shareholder has reviewed and is familiar with the Registration
         Statement and the Prospectus and neither the Prospectus nor any
         amendments or supplements thereto includes any untrue statement of a
         material fact or
   13
         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; such Selling Shareholder is not prompted to
         sell the Securities to be sold by such Selling Shareholder hereunder by
         any information concerning the Company or any subsidiary of the Company
         which is not set forth in the Prospectus.

                  (ii) Authorization of Agreements. Each Selling Shareholder has
         the full right, power and authority to enter into this Agreement and a
         Power of Attorney and Custody Agreement (the "Power of Attorney and
         Custody Agreement") and to sell, transfer and deliver the Securities to
         be sold by such Selling Shareholder hereunder. The execution and
         delivery of this Agreement and the Power of Attorney and Custody
         Agreement and the sale and delivery of the Securities to be sold by
         such Selling Shareholder and the consummation of the transactions
         contemplated herein and compliance by such Selling Shareholder with its
         obligations hereunder have been duly authorized by such Selling
         Shareholder and do not and will not, whether with or without the giving
         of notice or passage of time or both, conflict with or constitute a
         breach of, or default under, or result in the creation or imposition of
         any tax, lien, charge or encumbrance upon the Securities to be sold by
         such Selling Shareholder or any property or assets of such Selling
         Shareholder pursuant to any contract, indenture, mortgage, deed of
         trust, loan or credit agreement, note, license, lease or other
         agreement or instrument to which such Selling Shareholder is a party or
         by which such Selling Shareholder may be bound, or to which any of the
         property or assets of such Selling Shareholder is subject, nor will
         such action result in any violation of the provisions of the charter or
         by-laws or other organizational instrument of such Selling Shareholder,
         if applicable, or any applicable treaty, law, statute, rule,
         regulation, judgment, order, writ or decree of any government,
         government instrumentality or court, domestic or foreign, having
         jurisdiction over such Selling Shareholder or any of its properties.

                  (iii) Good and Marketable Title. Such Selling Shareholder has
         and will at the Closing Time and, if any
   14
         Option Securities are purchased, on the Date of Delivery, have good and
         marketable title to the Securities to be sold by such Selling
         Shareholder hereunder, free and clear of any security interest,
         mortgage, pledge, lien, charge, claim, equity or encumbrance of any
         kind, other than pursuant to this Agreement; and upon delivery of such
         Securities and payment of the purchase price therefor as herein
         contemplated, assuming each such Underwriter has no notice of any
         adverse claim, each of the Underwriters will receive good and
         marketable title to the Securities purchased by it from such Selling
         Shareholder, free and clear of any security interest, mortgage, pledge,
         lien, charge, claim, equity or encumbrance of any kind.

                  (iv) Due Execution of Power of Attorney and Custody Agreement.
         Such Selling Shareholder has duly executed and delivered, in the form
         heretofore furnished to the Representatives, the Irrevocable Power of
         Attorney with [Ronald R. Charnock and Donald C. Yount, Jr.], or either
         of them, as attorney-in-fact (the "Attorney-in-Fact") and the Custody
         Agreement with the Company as custodian (the "Custodian")(together, the
         "Power of Attorney and Custody Agreement"); the Custodian is authorized
         to deliver the Securities to be sold by such Selling Shareholder
         hereunder and to accept payment therefor; and the Attorney-in-Fact is
         authorized to execute and deliver this Agreement and the certificate
         referred to in Section 5(f) or that may be required pursuant to
         Sections 5(1) and 5(m) on behalf of such Selling Shareholder, to sell,
         assign and transfer to the Underwriters the Securities to be sold by
         such Selling Shareholder hereunder, to determine the purchase price to
         be paid by the Underwriters to such Selling Shareholder, as provided in
         Section 2(a) hereof, to authorize the delivery of the Securities to be
         sold by such Selling Shareholder hereunder, to accept payment therefor,
         and otherwise to act on behalf of such Selling Shareholder in
         connection with this Agreement.

                   (v) Absence of Manipulation. Such Selling Shareholder has not
         taken, and will not take, directly or indirectly, any action which is
         designed to or which has constituted or which might reasonably be
         expected to cause or result in stabilization or manipulation of the
         price of any security
   15
         of the Company to facilitate the sale or resale of the
         Securities.

                  (vi) Absence of Further Requirements. No filing with, or
         consent, approval, authorization, order, registration, qualification or
         decree of, any court or governmental authority or agency, domestic or
         foreign, is necessary or required for the performance by such Selling
         Shareholder of its obligations hereunder or in the Power of Attorney
         and Custody Agreement, or in connection with the sale and delivery of
         the Securities hereunder or the consummation of the transactions
         contemplated by this Agreement.

                 (vii) Restriction on Sale of Securities. During a period of 180
         days from the date of the Prospectus, such Selling Shareholder will
         not, without the prior written consent of Merrill Lynch, (i) offer,
         pledge, sell, contract to sell, sell any option or contract to
         purchase, purchase any option or contract to sell, grant any option,
         right or warrant to purchase or otherwise transfer or dispose of,
         directly or indirectly, any share of Common Stock or any securities
         convertible into or exercisable or exchangeable for Common Stock or
         file any registration statement under the 1933 Act with respect to any
         of the foregoing or (ii) enter into any swap or any other agreement or
         any transaction that transfers, in whole or in part, directly or
         indirectly, the economic consequence of ownership of the Common Stock,
         whether any such swap or transaction described in clause (i) or (ii)
         above is to be settled by delivery of Common Stock or such other
         securities, in cash or otherwise. The foregoing sentence shall not
         apply to the Securities to be sold hereunder.

                (viii) Certificates Suitable for Transfer. Certificates for all
         of the Securities to be sold by such Selling Shareholder pursuant to
         this Agreement, in suitable form for transfer by delivery or
         accompanied by duly executed instruments of transfer or assignment in
         blank with signatures guaranteed, have been placed in custody with the
         Custodian with irrevocable conditional instructions to deliver such
         Securities to the Underwriters pursuant to this Agreement.
   16
                  (ix) No Association with NASD. Neither such Selling
         Shareholder nor any affiliates of such Selling Shareholder, directly or
         indirectly through one or more intermediaries, controls, or is
         controlled by, or is under common control with, or has any other
         association with (within the meaning of Article I, Section 1(m) of the
         By-laws of the National Association of Securities Dealers, Inc.), any
         member firm of the National Association of Securities Dealers, Inc.

         (c) Officer's Certificates. Any certificate signed by any officer of
the Company or any of its Subsidiaries delivered to the Representatives or to
counsel for the Underwriters shall be deemed a representation and warranty by
the Company to each Underwriter as to the matters covered thereby, and any
certificate signed by or on behalf of the Selling Shareholders as such and
delivered to the Representatives or to counsel for the Underwriters pursuant to
the terms of this Agreement shall be deemed a representation and warranty by
such Selling Shareholder to the Underwriters as to the matters covered thereby.

         SECTION 2. Sale and Delivery to Underwriters; Closing.

         (a) Initial Securities. On the basis of the representations and
warranties herein contained and subject to the terms and conditions herein set
forth, the Company agrees to sell to each Underwriter, severally and not
jointly, and each Underwriter, severally and not jointly, agrees to purchase
from the Company, at the price per share set forth in Schedule C, that
proportion of the number of Initial Securities which the number of Initial
Securities set forth in Schedule A opposite the name of such Underwriter, plus
any additional number of Initial Securities which such Underwriter may become
obligated to purchase pursuant to the provisions of Section 10 hereof, bears to
the total number of Initial Securities, subject, in each case, to such
adjustments among the Underwriters as the Representatives in their sole
discretion shall make to eliminate any sales or purchases of fractional
securities.

         (b) Option Securities. In addition, on the basis of the representations
and warranties herein contained and subject to the terms and conditions herein
set forth, the Company and the Selling Shareholders, acting severally and not
jointly, hereby grant an option to the Underwriters, severally and not jointly,
to purchase up to an additional 330,000 shares of Common Stock,
   17
as set forth on Schedule B, at the price per share set forth in Schedule C, less
an amount per share equal to any dividends or distributions declared by the
Company and payable on the Initial Securities but not payable on the Option
Securities. The option hereby granted will expire 30 days after the date hereof
and may be exercised in whole or in part from time to time only for the purpose
of covering over-allotments which may be made in connection with the offering
and distribution of the Initial Securities upon notice by the Representatives to
the Company and the Selling Shareholders setting forth the number of Option
Securities as to which the several Underwriters are then exercising the option
and the time and date of payment and delivery for such Option Securities. Any
such time and date of delivery (a "Date of Delivery") shall be determined by the
Representatives, but shall not be later than seven full business days after the
exercise of said option, nor in any event prior to the Closing Time, as
hereinafter defined. If the option is exercised as to all or any portion of the
Option Securities, the Company and each Selling Shareholder, acting severally
and not jointly, will sell that proportion of the Option Securities then being
purchased which the Maximum Number of Option Securities set forth opposite the
name of such person in Schedule B hereto bears to the aggregate Maximum Number
of Option Securities to be sold by the Company and the Selling Shareholders in
the aggregate, and each of the Underwriters, acting severally and not jointly,
will purchase that proportion of the total number of Option Securities then
being purchased which the number of Initial Securities set forth in Schedule A
opposite the name of such Underwriter bears to the total number of Initial
Securities, subject in each case to such adjustments as the Representatives in
their discretion shall make to eliminate any sales or purchases of fractional
shares.

         (c) Payment. Payment of the purchase price for, and delivery of
certificates for, the Initial Securities shall be made at the offices of Hale
and Dorr, Washington, D.C., or at such other place as shall be agreed upon by
the Representatives and the Company at 10:00 A.M. (Eastern time) on the third
business day (or the fourth business day, if the pricing occurs after 4:30 P.M.
(Eastern time) pursuant to Rule 15c6-1(c) of the Securities Exchange Act of 1934
(the "1934 Act")) after the date hereof (unless postponed in accordance with the
provisions of
   18
Section 10), or such other time not later than ten business days after such date
as shall be agreed upon by the Representatives and the Company (such time and
date of payment and delivery being herein called "Closing Time").

         In addition, in the event that any or all of the Option Securities are
purchased by the Underwriters, payment of the purchase price for, and delivery
of certificates for, such Option Securities shall be made at the above-mentioned
offices, or at such other place as shall be agreed upon by the Representatives,
the Company and the Selling Shareholders on each Date of Delivery as specified
in the notice from the Representatives to the Company and the Selling
Shareholders.

         Payment shall be made to the Company and the Selling Shareholders by
wire transfer of immediately available funds to bank accounts designated by the
Company and the Custodian pursuant to each Selling Shareholder's Power of
Attorney and Custody Agreement, as the case may be, against delivery to the
Representatives for the respective accounts of the Underwriters of certificates
for the Securities to be purchased by them. It is understood that each
Underwriter has authorized the Representatives, for its account, to accept
delivery of, receipt for, and make payment of the purchase price for, the
Initial Securities and the Option Securities, if any, which it has agreed to
purchase. Merrill Lynch, individually and not as representative of the
Underwriters, may (but shall not be obligated to) make payment of the purchase
price for the Initial Securities or the Option Securities, if any, to be
purchased by any Underwriter whose funds have not been received by the Closing
Time or the relevant Date of Delivery, as the case may be, but such payment
shall not relieve such Underwriter from its obligations hereunder.

         (d) Denominations; Registration. Certificates for the Initial
Securities and the Option Securities, if any, shall be in such denominations and
registered in such names as the Representatives may request in writing at least
one full business day before the Closing Time or the relevant Date of Delivery,
as the case may be. The certificates for the Initial Securities and the Option
Securities, if any, will be made available for examination and packaging by the
Representatives in The City of New York not later than 10:00 A.M. (Eastern time)
on the business
   19
day prior to the Closing Time or the relevant Date of Delivery, as the case may
be.

         SECTION 3. Covenants of the Company. The Company covenants with each
Underwriter as follows:

         (a) Compliance with Securities Regulations and Commission Requests. The
Company, subject to Section 3(b), will comply with the requirements of Rule 430A
or Rule 434, as applicable, and will notify the Representatives immediately, and
confirm the notice in writing, (i) when any post-effective amendment to the
Registration Statement shall become effective, or any supplement to the
Prospectus or any amended Prospectus shall have been filed, (ii) of the receipt
of any comments from the Commission, (iii) of any request by the Commission for
any amendment to the Registration Statement or any amendment or supplement to
the Prospectus or for additional information, and (iv) of the issuance by the
Commission of any stop order suspending the effectiveness of the Registration
Statement or of any order preventing or suspending the use of any preliminary
prospectus, or of the suspension of the qualification of the Securities for
offering or sale in any jurisdiction, or of the initiation or threatening of any
proceedings for any of such purposes. The Company will promptly effect the
filings necessary pursuant to Rule 424(b) and will take such steps as it deems
necessary to ascertain promptly whether the form of prospectus transmitted for
filing under Rule 424(b) was received for filing by the Commission and, in the
event that it was not, it will promptly file such prospectus. The Company will
make every reasonable effort to prevent the issuance of any stop order and, if
any stop order is issued, to obtain the lifting thereof at the earliest possible
moment.

         (b) Filing of Amendments. The Company will give the Representatives
notice of its intention to file or prepare any amendment to the Registration
Statement (including any filing under Rule 462(b)), any Term Sheet or any
amendment, supplement or revision to either the prospectus included in the
Registration Statement at the time it became effective or to the Prospectus,
will furnish the Representatives with copies of any such documents a reasonable
amount of time prior to such proposed filing or use, as the case may be, and
will not file or use any
   20
such document to which the Representatives or counsel for the Underwriters shall
object.

         (c) Delivery of Registration Statements. The Company has furnished or
will deliver to the Representatives and counsel for the Underwriters, without
charge, signed copies of the Registration Statement as originally filed and of
each amendment thereto (including exhibits filed therewith or incorporated by
reference therein) and signed copies of all consents and certificates of
experts, and (if requested) will also deliver to the Representatives, without
charge, a conformed copy of the Registration Statement as originally filed and
of each amendment thereto (without exhibits) for each of the Underwriters. The
copies of the Registration Statement and each amendment thereto furnished to the
Underwriters will be identical to the electronically transmitted copies thereof
filed with the Commission pursuant to EDGAR, except to the extent permitted by
Regulation S-T.

         (d) Delivery of Prospectuses. The Company has delivered to each
Underwriter, without charge, as many copies of each preliminary prospectus as
such Underwriter reasonably requested, and the Company hereby consents to the
use of such copies for purposes permitted by the 1933 Act. The Company will
furnish to each Underwriter, without charge, during the period when the
Prospectus is required to be delivered under the 1933 Act or the 1934 Act, such
number of copies of the Prospectus (as amended or supplemented) as such
Underwriter may reasonably request. The Prospectus and any amendments or
supplements thereto furnished to the Underwriters will be identical to the
electronically transmitted copies thereof filed with the Commission pursuant to
EDGAR, except to the extent permitted by Regulation S-T.

         (e) Continued Compliance with Securities Laws. The Company will comply
with the 1933 Act and the 1933 Act Regulations so as to permit the completion of
the distribution of the Securities as contemplated in this Agreement and in the
Prospectus. If at any time when a prospectus is required by the 1933 Act to be
delivered in connection with sales of the Securities, any event shall occur or
condition shall exist as a result of which it is necessary, in the opinion of
counsel for the Underwriters or for the Company, to amend the Registration
Statement or amend or supplement the Prospectus in order that the Prospectus
will not include any untrue statements of a material fact or omit to state
   21
a material fact necessary in order to make the statements therein not misleading
in the light of the circumstances existing at the time it is delivered to a
purchaser, or if it shall be necessary, in the opinion of such counsel, at any
such time to amend the Registration Statement or amend or supplement the
Prospectus in order to comply with the requirements of the 1933 Act or the 1933
Act Regulations, the Company will promptly prepare and file with the Commission,
subject to Section 3(b), such amendment or supplement as may be necessary to
correct such statement or omission or to make the Registration Statement or the
Prospectus comply with such requirements, and the Company will furnish to the
Underwriters such number of copies of such amendment or supplement as the
Underwriters may reasonably request.

         (f) Blue Sky Qualifications. The Company will use its best efforts, in
cooperation with the Underwriters, to qualify the Securities for offering and
sale under the applicable securities laws of such states and other jurisdictions
as the Representatives may designate and to maintain such qualifications in
effect for a period of not less than one year from the later of the effective
date of the Registration Statement and any Rule 462(b) Registration Statement;
provided, however, that the Company shall not be obligated to file any general
consent to service of process or to qualify as a foreign corporation or as a
dealer in securities in any jurisdiction in which it is not so qualified or to
subject itself to taxation in respect of doing business in any jurisdiction in
which it is not otherwise so subject. In each jurisdiction in which the
Securities have been so qualified, the Company will file such statements and
reports as may be required by the laws of such jurisdiction to continue such
qualification in effect for a period of not less than one year from the
effective date of the Registration Statement and any Rule 462(b) Registration
Statement.

         (g) Rule 158. The Company will timely file such reports pursuant to the
1934 Act as are necessary in order to make generally available to its
securityholders as soon as practicable an earnings statement for the purposes
of, and to provide the benefits contemplated by, the last paragraph of Section
11(a) of the 1933 Act.
   22
         (h) Use of Proceeds. The Company will use the net proceeds received by
it from the sale of the Securities in substantially the manner specified in the
Prospectus under "Use of Proceeds."

         (i) Listing. The Company will use its best efforts to effect and
maintain the quotation of the Common Stock (including the Securities) on the
Nasdaq National Market and will file with the Nasdaq National Market all
documents and notices required by the Nasdaq National Market of companies that
have securities that are traded in the over-the-counter market and quotations
for which are reported by the Nasdaq National Market.

         (j) Restriction on Sale of Securities. During a period of 180 days from
the date of the Prospectus, the Company will not, without the prior written
consent of Merrill Lynch, (i) directly or indirectly, offer, pledge, sell,
contract to sell, sell any option or contract to purchase, purchase any option
or contract to sell, grant any option, right or warrant to purchase or otherwise
transfer or dispose of any share of Common Stock or any securities convertible
into or exercisable or exchangeable for Common Stock or file any registration
statement under the 1933 Act with respect to any of the foregoing or (ii) enter
into any swap or any other agreement or any transaction that transfers, in whole
or in part, directly or indirectly, the economic consequence of ownership of the
Common Stock, whether any such swap or transaction described in clause (i) or
(ii) above is to be settled by delivery of Common Stock or such other
securities, in cash or otherwise. The foregoing sentence shall not apply to (A)
the Securities to be sold hereunder, (B) any shares of Common Stock issued by
the Company upon the exercise of an option or warrant or the conversion of a
security outstanding on the date hereof and referred to in the Prospectus or (C)
any shares of Common Stock issued or options to purchase Common Stock granted
pursuant to existing employee benefit plans of the Company referred to in the
Prospectus.

         (k) Reporting Requirements. The Company, during the period when the
Prospectus is required to be delivered under the 1933 Act or the 1934 Act, will
file all documents required to be filed with the Commission pursuant to the 1934
Act within the time periods required by the 1934 Act and the rules and
regulations of the Commission thereunder.
   23
         (l) Compliance with Rule 463. The Company will file with the Commission
such reports on Form SR as may be required pursuant to Rule 463 of the 1933 Act
Regulations.

         SECTION 4.  Payment of Expenses.

         (a) Expenses. The Company and the Selling Shareholders will pay or
cause to be paid all expenses incident to the performance of their obligations
under this Agreement, including (i) the preparation, printing and filing of the

                           (ii) The Company has corporate power and authority to
         own, lease and operate its properties and to conduct its business as
         described in the Prospectus and to enter into and perform its

                           (iii) The Company is duly qualified as a foreign
         corporation to transact business and is in good standing in each
         jurisdiction listed on Schedule D hereto.

                           (iv) The authorized, issued and outstanding capital
         stock of the Company is as set forth in the Prospectus in the column
         entitled "Actual" under the caption "Capitalization" (except for
         subsequent issuances, if any, pursuant to this Agreement or pursuant to
         reservations, agreements or employee benefit plans referred to in the
         Prospectus or pursuant to the exercise of convertible securities or
         options referred to in the Prospectus); the shares of issued and
         outstanding capital stock of the Company have been duly authorized and
         validly issued and are fully paid and non-assessable; and none of the
         outstanding shares of capital stock of the Company was issued in
         violation of the preemptive or other similar rights of any
         securityholder of the Company.

                           (v) The Securities to be purchased by the
         Underwriters from the Company have been duly authorized for issuance

         issued and delivered by the Company pursuant to this Agreement against
         payment of the
   26
         consideration set forth in this Agreement, will be validly issued and

                          (vi) The issuance and sale of the Securities by the
         Company is not subject to the preemptive or other similar rights of any
         securityholder of the Company arising by operation of law, under the
         charter or by-laws of the Company, or, to the best of such counsel's
         knowledge, under any agreement to which the Company or any of its
         Subsidiaries is a party or otherwise.

                         (vii) Each Subsidiary has been duly incorporated and is
         validly existing as a corporation in good standing under the laws of
         the jurisdiction of its incorporation, has corporate power and
         authority to own, lease and operate its properties and to conduct its
         business as described in the Prospectus and is duly qualified as a
         foreign corporation to transact business and is in good standing in
         each jurisdiction in which such qualification is required, whether by
         reason of the ownership or leasing of property or the conduct of
         business, except where the failure so to qualify or to be in good
         standing would not result in a Material Adverse Effect; except as
         otherwise disclosed in the Registration Statement, all of the issued

         authorized and validly issued, is fully paid and non-assessable and, to
         the best of such counsel's knowledge, is owned by the Company, directly
         or through subsidiaries, free and clear of any security interest,
         mortgage, pledge, lien, encumbrance, claim or equity (except that the
         Company has pledged all shares of stock in the Subsidiaries to Silicon
         Valley Bank to secure the line of credit described in the Prospectus);
         none of the outstanding shares of capital stock of any Subsidiary was
         issued in violation of the preemptive or similar rights of any
         securityholder of such Subsidiary arising by operation of law, under
         the charter or by-laws of such Subsidiary, or, to the best of such
         counsel's knowledge, under any agreement to which such Subsidiary is a
         party or otherwise.

                           (viii) This Agreement has been duly authorized,
         executed and delivered by the Company.
   27
                          (ix) The Registration Statement, including any Rule
         462(b) Registration Statement, has been declared effective under the
         1933 Act; any required filing of the Prospectus pursuant to Rule 424(b)
         has been made in the manner and within the time period required by Rule
         424(b); and, to the best of such counsel's knowledge, no stop order
         suspending the effectiveness of the Registration Statement or any Rule
         462(b) Registration Statement has been issued under the 1933 Act and,
         to the best of such counsel's knowledge, no proceedings for that
         purpose have been instituted or are pending or threatened by the
         Commission.

                           (x) The Registration Statement, including any Rule
         462(b) Registration Statement, the Rule 430A Information and the Rule
         434 Information, as applicable, the Prospectus, and each amendment or
         supplement to the Registration Statement and Prospectus, as of their
         respective effective or issue dates (other than the financial
         statements and supporting schedules included therein or omitted
         therefrom, as to which such counsel need express no opinion) complied
         as to form in all material respects with the requirements of the 1933
         Act and the 1933 Act Regulations.

                          (xi) If Rule 434 has been relied upon, the Prospectus
         was not "materially different," as such term is used in Rule 434, from
         the prospectus included in the Registration Statement at the time it
         became effective.

                         (xii) The form of certificate used to evidence the
         Common Stock complies in all material respects with all applicable
         statutory requirements, with any applicable requirements of the charter
         and by-laws of the Company and the requirements of the Nasdaq National
         Market.

                        (xiii) To the best of such counsel's knowledge, there is
         not pending or threatened any action, suit, proceeding, inquiry or
         investigation, to which the Company or any Subsidiary is a party, or to
         which the property of the Company or any Subsidiary is subject, before
         or brought by any court or governmental agency or body, domestic or
         foreign, which might reasonably be expected to result in a
   28
         Material Adverse Effect, or which might reasonably be expected to
         materially and adversely affect the properties or assets thereof or the
         consummation of the transactions contemplated in this Agreement or the
         performance by the Company of its obligations thereunder.

                         (xiv) The information in the Prospectus under the
         captions "Business -- Legal Proceedings," "Management -- Stock Plans,"
         "Description of Capital Stock" and "Shares Eligible for Future Sale"
         and in the Registration Statement under Items 14 and 15, to the extent
         that it constitutes matters of law, summaries of legal matters, the
         Company's charter, bylaws or employee benefit plans or legal
         proceedings, or legal conclusions, has been reviewed by such counsel
         and is correct in all material respects.

                          (xv) To the best of such counsel's knowledge, there
         are no statutes or regulations that are required to be described in the
         Prospectus that are not described as required.

                         (xvi) All descriptions in the Registration Statement of
         contracts and other documents to which the Company or its Subsidiaries
         are a party are accurate in all material respects; to the best of such
         counsel's knowledge, there are no franchises, contracts, indentures,
         mortgages, loan agreements, notes, leases or other instruments required
         to be described or referred to in the Registration Statement or to be
         filed as exhibits thereto other than those described or referred to
         therein or filed or incorporated by reference as exhibits thereto, and
         the descriptions thereof or references thereto are correct in all
         material respects.

                        (xvii) To the best of such counsel's knowledge, neither
         the Company nor any Subsidiary is in violation of its charter or
         by-laws and no default by the Company or any Subsidiary exists in the
         due performance or observance of any material obligation, agreement,
         covenant or condition contained in any contract, indenture, mortgage,
         loan agreement, note, lease or other agreement or instrument that is
         described or referred to in the Registration Statement or the
         Prospectus or filed or incorporated by reference as an exhibit to the
         Registration Statement.
   29
                       (xviii) No filing with, or authorization, approval,
         consent, license, order, registration, qualification or decree of, any
         court or governmental authority or agency, domestic or foreign (other
         than under the 1933 Act and the 1933 Act Regulations, which have been
         obtained, or as may be required under the securities or blue sky laws
         of the various states, as to which such counsel need express no
         opinion) is necessary or required in connection with the due
         authorization, execution and delivery of this Agreement or for the
         offering, issuance, sale or delivery of the Securities.

                         (xix) The execution, delivery and performance of this
         Agreement and the consummation of the transactions contemplated in this
         Agreement and in the Registration Statement (including the issuance and
         sale of the Securities) and compliance by the Company with its
         obligations under this Agreement do not and will not, whether with or
         without the giving of notice or lapse of time or both, conflict with or
         constitute a breach of, or default or Repayment Event (as defined in
         Section 1(a)(x) of this Agreement) under or result in the creation or
         imposition of any lien, charge or encumbrance upon any property or
         assets of the Company or any Subsidiary pursuant to any contract,
         indenture, mortgage, deed of trust, loan or credit agreement, note,
         lease or any other agreement or instrument, known to such counsel, to
         which the Company or any Subsidiary is a party or by which it or any of
         them may be bound, or to which any of the property or assets of the
         Company or any Subsidiary is subject (except for such conflicts,
         breaches or defaults or liens, charges or encumbrances that would not
         have a Material Adverse Effect), nor will such action result in any
         violation of the provisions of the charter or by-laws of the Company or
         any Subsidiary, or any applicable law, statute, rule, regulation,
         judgment, order, writ or decree, known to such counsel, of any
         government, government instrumentality or court, domestic or foreign,
         having jurisdiction over the Company or any Subsidiary or any of their
         respective properties, assets or operations.
   30
                          (xx) To the best of such counsel's knowledge, there
         are no persons with registration rights or other similar rights, which
         have not been satisfied or waived, to have any securities registered
         pursuant to the Registration Statement or otherwise registered by the
         Company under the 1933 Act.

                         (xxi) The Company is not, and upon the issuance and
         sale of the Securities as contemplated in this Agreement and the
         application of the net proceeds therefrom 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 1940 Act.

                  Such opinion shall also include a statement to the effect that
         nothing has come to such counsel's attention that would lead it to
         believe that the Registration Statement or any amendment thereto,
         including the Rule 430A Information and Rule 434 Information (if
         applicable), (except for financial statements and schedules and other
         financial data included therein or omitted therefrom, as to which such
         counsel need make no statement), at the time such Registration
         Statement or any such 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 amendment or
         supplement thereto (except for financial statements and schedules and
         other financial data included therein or omitted therefrom, as to which
         such counsel need make no statement), at the time the Prospectus was
         issued, at the time any such amended or supplemented prospectus was
         issued or at the Closing Time, included or includes an 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 such opinion, such counsel may rely as to matters of fact
(but not as to legal conclusions), to the extent they deem proper, on
certificates of responsible officers of the Company and public officials, and as
to matters governed by the laws of states other than the Commonwealth of
Massachusetts, the Delaware General Corporation Law or Federal laws, on local
   31
counsel in such jurisdictions. Such opinion shall not state that it is to be
governed or qualified by, or that it is otherwise subject to, any treatise,
written policy or other document relating to legal opinions, including, without
limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991).

         (c) Opinion of Counsel for the Selling Shareholders. At Closing Time,
the Representatives shall have received the favorable opinion, dated as of
Closing Time, of ________, counsel for the Selling Shareholders, in form and
substance satisfactory to counsel for the Underwriters, to the effect that:

                  (i) No filing with, or consent, approval, authorization,
         license, order, registration, qualification or decree of, any court or
         governmental authority or agency, domestic or foreign, (other than the
         issuance of the order of the Commission declaring the Registration
         Statement effective and such authorizations, approvals or consents as
         may be necessary under state securities laws, as to which such counsel
         need express no opinion) is necessary or required to be obtained by the
         Selling Shareholders for the performance by each Selling Shareholder of
         its obligations under this Agreement or in the Power of Attorney and
         Custody Agreement, or in connection with the offer, sale or delivery of
         the Securities.

                  (ii) Each Power of Attorney and Custody Agreement has been
         duly executed and delivered by the respective Selling Shareholder named
         therein and constitutes the legal, valid and binding agreement of such
         Selling Shareholder.

                  (iii) This Agreement has been duly authorized, executed and
         delivered by or on behalf of each Selling Shareholder.

                  (iv) Each Attorney-in-Fact has been duly authorized by the
         Selling Shareholders to deliver the Securities on behalf of the Selling
         Shareholders in accordance with the terms of this Agreement.

                  (v)  The execution, delivery and performance of this

         transactions contemplated in this Agreement and in the Registration
         Statement and compliance by the Selling Shareholders with their
         obligations under this Agreement have been duly authorized by all
         necessary action on the part of the Selling Shareholders and do not and
         will not, whether with or without the giving of notice or passage of
         time or both, conflict with or constitute a breach of, or default under
         or result in the creation or imposition of any tax, lien, charge or
         encumbrance upon the Securities or any property or assets of the
         Selling Shareholders pursuant to, any contract, indenture, mortgage,
         deed of trust, loan or credit agreement, note, license, lease or other
         instrument or agreement to which any Selling Shareholder is a party or
         by which it may be bound, or to which any of the property or assets of
         the Selling Shareholders may be subject nor will such action result in
         any violation of the provisions of the charter or by-laws of the
         Selling Shareholders, if applicable, or any law, administrative
         regulation, judgment or order of any governmental agency or body or any
         administrative or court decree having jurisdiction over such Selling
         Shareholder or any of its properties.

                  (vi) To the best of such counsel's knowledge, each Selling
         Shareholder has valid and marketable title to the Securities to be sold
         by such Selling Shareholder pursuant to this Agreement, free and clear
         of any pledge, lien, security interest, charge, claim, equity or
         encumbrance of any kind, and has full right, power and authority to
         sell, transfer and deliver such Securities pursuant to this Agreement.
         By delivery of a certificate or certificates therefor, such Selling
         Shareholder will transfer to the Underwriters who have purchased such
         Securities pursuant to this Agreement (without notice of any defect in
         the title of such Selling Shareholder and who are otherwise bona fide
         purchasers for purposes of the Uniform Commercial Code) valid and
         marketable title to such Securities, free and clear of any pledge,
         lien, security interest, charge, claim, equity or encumbrance of any
         kind.

issuance and sale of the Securities as herein contemplated, or in order to
evidence the accuracy of any of the representations or warranties, or the
fulfillment of any of the conditions, herein contained; and all proceedings

terminated by the Representatives by notice to the Company at any time at or
prior to Closing Time or such Date of Delivery, as the case may be, and such
termination shall be without liability of any party to any other party except as
provided in Section 4 and except that Sections 1, 6, 7 and 8 shall survive any
such termination and remain in full force and effect.

         SECTION 6.  Indemnification.

         (a) Indemnification of Underwriters. The Company and the Selling
Shareholders, jointly and severally, agree to indemnify
   37
and hold harmless each Underwriter and each person, if any, who controls any
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act as follows:

                  (i) against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, arising out of any untrue statement or
         alleged untrue statement of a material fact contained in the
         Registration Statement (or any amendment thereto), including the Rule
         430A Information and the Rule 434 Information, if applicable, or the
         omission or alleged omission therefrom of a material fact required to
         be stated therein or necessary to make the statements therein not
         misleading or arising out of any untrue statement or alleged untrue
         statement of a material fact included in any preliminary prospectus or
         the Prospectus (or any amendment or supplement thereto), or the
         omission or alleged omission therefrom of a material fact necessary in
         order to make the statements therein, in the light of the circumstances
         under which they were made, not misleading;

                  (ii) against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, to the extent of the aggregate amount
         paid in settlement of any litigation, or any investigation or
         proceeding by any governmental agency or body, commenced or threatened,
         or of any claim whatsoever based upon any such untrue statement or
         omission, or any such alleged untrue statement or omission provided
         that (subject to Section 6(d) below) any such settlement is effected
         with the written consent of the Company and the Selling Shareholders;
         and

                  (iii) against any and all expense whatsoever, as incurred
         (including the fees and disbursements of counsel chosen by Merrill
         Lynch), reasonably incurred in investigating, preparing or defending
         against any litigation, or any investigation or proceeding by any
         governmental agency or body, commenced or threatened, or any claim
         whatsoever based upon any such untrue statement or omission, or any
         such alleged untrue statement or omission, to the extent that any such
         expense is not paid under (i) or (ii) above;
   38
         provided, however that this indemnity agreement shall not (i) apply to
         any loss, liability, claim, damage or expense to the extent arising out
         of any untrue statement or omission or alleged untrue statement or
         omission made in reliance upon and in conformity with written
         information furnished to the Company by any Underwriter through Merrill
         Lynch expressly for use in the Registration Statement (or any amendment
         thereto), including the Rule 430A Information and the Rule 434
         Information, if applicable, or any preliminary prospectus or the
         Prospectus (or any amendment or supplement thereto) or (ii) inure to
         the benefit of any Underwriter from whom the person asserting any loss,
         liability, claim, damage or expense purchased Securities, or any person
         controlling such Underwriter, if a copy of the Prospectus (as then
         amended or supplemented if the Company shall have furnished any
         amendments or supplements thereto) was not sent or given by or on
         behalf of such Underwriter to such person, if required by law to have
         been so delivered, at or prior to the written confirmation of such
         Securities to such person, and if the Prospectus (as so amended or
         supplemented) would have cured any defect giving rise to such loss,
         liability, claim, damage or expense; and further provided that each
         Selling Shareholder's aggregate liability under this Section 6 shall be
         limited to an amount equal to the net proceeds (after deducting the
         underwriting discount, but before deducting expenses) received by such
         Selling Shareholder from the sale of Securities pursuant to this
         Agreement.

                  (b) Indemnification of Company, Directors and Officers and
         Selling Shareholders. Each Underwriter severally agrees to indemnify
         and hold harmless the Company, its directors, each of its officers who
         signed the Registration Statement, and each person, if any, who
         controls the Company within the meaning of Section 15 of the 1933 Act
         or Section 20 of the 1934 Act, and each Selling Shareholder and each
         person, if any, who controls any Selling Shareholder within the meaning
         of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any
         and all loss, liability, claim, damage and expense described in the
         indemnity contained in subsection (a) of this Section , as incurred,
         but only with respect to untrue statements or omissions, or alleged
         untrue statements or omissions, made in the Registration Statement (or
         any amendment thereto), including the Rule 430A Information and
   39
         the Rule 434 Information, if applicable, or any preliminary prospectus
         or the Prospectus (or any amendment or supplement thereto) in reliance
         upon and in conformity with written information furnished to the
         Company by such Underwriter through Merrill Lynch expressly for use in
         the Registration Statement (or any amendment thereto) or such
         preliminary prospectus or the Prospectus (or any amendment or
         supplement thereto).

         (c) Actions against Parties; Notification. Each indemnified party shall
give notice as promptly as reasonably practicable to each indemnifying party of
any action commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify all indemnifying party shall not relieve
such indemnifying party from any liability hereunder to the extent it is not
materially prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement. In the case of parties indemnified pursuant to Section 6(a) above,
counsel to the indemnified parties shall be selected by Merrill Lynch, and, in
the case of parties indemnified pursuant to Section 6(b) above, counsel to the
indemnified parties shall be selected by the Company or the Selling
Shareholders. An indemnifying party may participate at its own expense in the
defense of any such action; provided, however, that counsel to the indemnifying
party shall not (except with the consent of the indemnified party) also be
counsel to the indemnified party. In no event shall the indemnifying parties be
liable for fees and expenses of more than one counsel (in addition to any local
counsel) separate from their own counsel for all indemnified parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances.
No indemnifying party shall, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 6 or Section 7 hereof (whether or not the indemnified parties
are actual or potential parties thereto), unless such settlement, compromise or
consent (i) includes an unconditional
   40
release of each indemnified party from all liability arising out of such
litigation, investigation, proceeding or claim and (ii) does not include a
statement as to or an admission of fault, culpability or a failure to act by or
on behalf of any indemnified party.

         (d) Settlement without Consent if Failure to Reimburse. If at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 6(a)(ii) effected without its written consent if (i) such settlement is
entered into more than 45 days after receipt by such indemnifying party of the
aforesaid request, (ii) such indemnifying party shall have received notice of
the terms of such settlement at least 30 days prior to such settlement being
entered into and (iii) such indemnifying party shall not have reimbursed such
indemnified party in accordance with such request prior to the date of such
settlement.

         SECTION 7. Contribution. If the indemnification provided for in Section
6 hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, liabilities, claims, damages or
expenses referred to therein, then each indemnifying party shall contribute to
the aggregate amount of such losses, liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Selling Shareholders on the one hand and the Underwriters on the other hand from
the offering of the Securities pursuant to this Agreement or (ii) if the
allocation provided by clause (i) 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 and the
Selling Shareholders on the one hand and of the Underwriters on the other hand
in connection with the statements or omissions which resulted in such losses,
liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations. Neither the Company, any Selling Shareholder nor any
Underwriter shall in any case be required to contribute any amounts under this
Section 7 which in the aggregate exceed the amount of indemnification payments
that the Company, such Selling Shareholder or Underwriter, as the case may be,
would otherwise

   41
have been obligated to make under Section 6 above, had the indemnification
provided for in such Section 6 been available.

         The relative benefits received by the Company and the Selling
Shareholders on the one hand and the Underwriters on the other hand in
connection with the offering of the Securities pursuant to this Agreement shall
be deemed to be in the same respective proportions as the total net proceeds
from the offering of the Securities pursuant to this Agreement (before deducting
expenses) received by the Company and the Selling Shareholders and the total
underwriting discount received by the Underwriters, in each case as set forth on
the cover of the Prospectus, or, if Rule 434 is used, the corresponding location
on the Term Sheet bear to the aggregate initial public offering price of the
Securities as set forth on such cover.

         The relative fault of the Company and the Selling Shareholders on the
one hand and the Underwriters on the other hand shall be determined by reference
to, among other things, whether any such untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company or the Selling Shareholders or by the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

         The Company, the Selling Shareholders and the Underwriters agree that
it would not be just and equitable if contribution pursuant to this Section 7
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 which does not
take account of the equitable considerations referred to above in this Section 
7. The aggregate amount of losses, liabilities, claims, damages and expenses
incurred by an indemnified party and referred to above in this Section 7 shall
be deemed to include any legal or other expenses reasonably incurred by such
indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.
   42
         Notwithstanding the provisions of this Section 7, no Underwriter shall
be required to contribute any amount in excess of the amount by which the total
price at which the Securities underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of any such untrue or
alleged untrue statement or omission or alleged omission.

         No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

         For purposes of this Section 7, each person, if any, who controls an
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 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 or any
Selling Shareholder within the meaning of Section 15 of the 1933 Act or Section 
20 of the 1934 Act shall have the same rights to contribution as the Company or
such Selling Shareholder, as the case may be. The Underwriters' respective
obligations to contribute pursuant to this Section 7 are several in proportion
to the number of Initial Securities set forth opposite their respective names in
Schedule A hereto and not joint.

         The provisions of this Section shall not affect any agreement among the
Company and the Selling Shareholders with respect to contribution.

         SECTION 8. Representations, Warranties and Agreements to Survive
Delivery. All representations, warranties and agreements contained in this
Agreement or in certificates of officers of the Company or any of its
subsidiaries or the Selling Shareholders submitted pursuant hereto, shall remain
operative and in full force and effect, regardless of any investigation made by
or on behalf of any Underwriter or controlling person, or by or on behalf of the
Company or the Selling Shareholders and shall survive delivery of the Securities
to the Underwriters.

         SECTION 9.  Termination of Agreement.
   43
         (a) Termination; General. The Representatives may terminate this
Agreement, by notice to the Company and the Selling Shareholders, at any time at
or prior to Closing Time (i) if there has been, since the time of execution of
this Agreement or since the respective dates as of which information is given in
the Prospectus, any material adverse change in the condition, financial or
otherwise, or in the earnings, business affairs or business prospects of the
Company and its subsidiaries considered as one enterprise, whether or not
arising in the ordinary course of business, or (ii) if there has occurred any
material adverse change in the financial markets in the United States or the
international financial markets, any outbreak of hostilities or escalation
thereof or other calamity or crisis or any change or development involving a
prospective change in national or international political, financial or economic
conditions, in each case the effect of which is such as to make it, in the
judgment of the Representatives, impracticable to market the Securities or to
enforce contracts for the sale of the Securities, or (iii) if trading in any
securities of the Company has been suspended or materially limited by the
Commission or the Nasdaq National Market, or if trading generally on the
American Stock Exchange or the New York Stock Exchange or in the Nasdaq National
Market has been suspended or materially limited, or minimum or maximum prices
for trading have been fixed, or maximum ranges for prices have been required, by
any of said exchanges or by such system or by order of the Commission, the
National Association of Securities Dealers, Inc. or any other governmental
authority, or (iv) if a banking moratorium has been declared by either Federal
or New York authorities.

         (b) Liabilities. If this Agreement is terminated pursuant to this
Section , such termination shall be without liability of any party to any other
party except as provided in Section 4 hereof, and provided further that Sections
1, 6, 7 and 8 shall survive such termination and remain in full force and
effect.

         SECTION 10. Default by One or More of the Underwriters. If one or more
of the Underwriters shall fail at Closing Time or a Date of Delivery to purchase
the Securities which it or they are obligated to purchase under this Agreement
(the "Defaulted Securities"), the Representatives shall have the right, within
24 hours thereafter, to make arrangements for one or more of the
   44
non-defaulting Underwriters, or any other underwriters, to purchase all, but not
less than all, of the Defaulted Securities in such amounts as may be agreed upon
and upon the terms herein set forth; if, however, the Representatives shall not
have completed such arrangements within such 24-hour period, then:

         (a) if the number of Defaulted Securities does not exceed 10% of the
number of Securities to be purchased on such date, each of the non-defaulting
Underwriters shall be obligated, severally and not jointly, to purchase the full
amount thereof in the proportions that their respective underwriting obligations
hereunder bear to the underwriting obligations of all non-defaulting
Underwriters, or

         (b) if the number of Defaulted Securities exceeds 10% of the number of
Securities to be purchased on such date, this Agreement or, with respect to any
Date of Delivery which occurs after the Closing Time, the obligation of the
Underwriters to purchase and of the Company to sell the Option Securities to be
purchased and sold on such Date of Delivery shall terminate without liability on
the part of any non-defaulting Underwriter.

         No action taken pursuant to this Section shall relieve any defaulting
Underwriter from liability in respect of its default.

         In the event of any such default which does not result in a termination
of this Agreement or, in the case of a Date of Delivery which is after the
Closing Time, which does not result in a termination of the obligation of the
Underwriters to purchase and the Company to sell the relevant Option Securities,
as the case may be, either the (i) Representatives or (ii) the Company and any
Selling Shareholder shall have the right to postpone Closing Time or the
relevant Date of Delivery, as the case may be, for a period not exceeding seven
days in order to effect any required changes in the Registration Statement or
Prospectus or in any other documents or arrangements. As used herein, the term
"Underwriter" includes any person substituted for an Underwriter under this
Section 10.

         SECTION 11. Default by one or more of the Selling Shareholders or the
Company.

         (a) If a Selling Shareholder shall fail at a Date of Delivery to sell
and deliver the number of Securities which such
   45
Selling Shareholder is obligated to sell hereunder, and the remaining Selling
Shareholders do not exercise the right hereby granted to increase, pro rata or
otherwise, the number of Securities to be sold by them hereunder to the total
number to be sold by all Selling Shareholders as set forth in Schedule B hereto,
then the Underwriters may, at the option of the Representatives, by notice from
the Representatives to the Company and the non-defaulting Selling Shareholders,
either (a) terminate this Agreement without any liability on the fault of any
non-defaulting party except that the provisions of Sections 1, 4, 6, 7 and 8
shall remain in full force and effect or (b) elect to purchase the Securities
which the non-defaulting Selling Shareholders and the Company have agreed to
sell hereunder. No action taken pursuant to this Section 11 shall relieve any
Selling Shareholder so defaulting from liability, if any, in respect of such
default.

         In the event of a default by any Selling Shareholder as referred to in
this Section 11, each of the Representatives and the non-defaulting Selling
Shareholders shall have the right to postpone the Date of Delivery for a period
not exceeding seven days in order to effect any required change in the
Registration Statement or Prospectus or in any other documents or arrangements.

         (b) If the Company shall fail at Closing Time or at the Date of
Delivery to sell the number of Securities that it is obligated to sell
hereunder, then this Agreement shall terminate without any liability on the part
of any nondefaulting party; provided, however, that the provisions of Sections 
1, 4, 6, 7 and 8 shall remain in full force and effect. No action taken pursuant
to this Section shall relieve the Company from liability, if any, in respect of
such default.

         SECTION 12. Notices. All notices and other communications hereunder
shall be in writing and shall be deemed to have been duly given if mailed or
transmitted by any standard form of telecommunication. Notices to the
Underwriters shall be directed to the Representatives in care of Merrill Lynch

         SECTION 13. Parties. This Agreement shall each inure to the benefit of
and be binding upon the Underwriters, the Company and the Selling Shareholders
and their respective successors. Nothing expressed or mentioned in this
Agreement is intended or shall be construed to give any person, firm or
corporation, other than the Underwriters, the Company, the Selling Shareholders
and their respective successors and the controlling persons and officers and
directors referred to in Sections 6 and 7 and their heirs and legal
representatives, any legal or equitable right, remedy or claim under or in
respect of this Agreement or any provision herein contained. This Agreement and
all conditions and provisions hereof are intended to be for the sole and
exclusive benefit of the Underwriters, the Company, the Selling Shareholders and
their respective successors, and said controlling persons and officers and
directors and their heirs and legal representatives, and for the benefit of no
other person, firm or corporation. No purchaser of Securities from any
Underwriter shall be deemed to be a successor by reason merely of such purchase.

         SECTION 14. GOVERNING LAW AND TIME. THIS AGREEMENT SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. SPECIFIED
TIMES OF DAY REFER TO NEW YORK CITY TIME.
