Ladies and Gentlemen:

proposes, subject to the terms and conditions stated herein, to issue and sell
to the Underwriters named in Schedule I hereto (the "Underwriters") an aggregate
of 1,000,000 shares of Common Stock, $.001 par value per share ("Stock") of the
Company and the stockholders of the Company named in Schedule II-A hereto (the
"Selling Stockholders") propose, subject to the terms and conditions stated
herein, severally to sell to the Underwriters an aggregate of 2,800,000 shares
and, at the election of the Underwriters, certain of the Selling Stockholders
named in Schedule II-B hereto (the "Optional Selling Stockholders") propose,

         1. (a) The Company represents and warrants to, and agrees with, each of
the Underwriters that:

            (i) A registration statement on Form S-1 (File No. 333-31770)

         Registration Statement") in respect of the Shares has been filed with
         the Securities and Exchange Commission (the "Commission"); the Initial
         Registration Statement and any post-effective amendment thereto, each
         in the form heretofore delivered to you for each of the other
         Underwriters, and, excluding exhibits thereto, have been declared
         effective by the Commission in such form; other than a registration
         statement, if any, increasing the size of the offering (a "Rule 462(b)
         Registration Statement"), filed pursuant to Rule 462(b) under the
         Securities Act of 1933, as amended (the "Act"), which became effective
         upon filing, no other document with respect to the Initial Registration
         Statement has heretofore been filed with the Commission; and no stop
         order suspending the effectiveness of the Initial Registration






         Statement, any post-effective amendment hereto or the Rule 462(b)
         Registration Statement, if any, has been issued and no proceeding for
         that purpose has been initiated or threatened by the Commission (any
         preliminary prospectus included in the Initial Registration Statement
         or filed with the Commission pursuant to Rule 424(a) of the rules and
         regulations of the Commission under the Act is hereinafter called a
         "Preliminary Prospectus"; the various parts of the Initial Registration
         Statement, any post-effective amendment and the Rule 462(b)
         Registration Statement, if any, including all exhibits thereto and
         including the information contained in the form of final prospectus
         filed with the Commission pursuant to Rule 424(b) under the Act in
         accordance with Section 5(a) hereof and deemed by virtue of Rule 430A
         under the Act to be part of the Initial Registration Statement at the
         time it was declared effective, each as amended at the time such part
         of the Initial Registration Statement became effective or such part of
         the Rule 462(b) Registration Statement, if any, became or hereafter
         becomes effective, are hereinafter collectively called the
         "Registration Statement"; and such final prospectus, in the form first
         filed pursuant to Rule 424(b) under the Act, is hereinafter called the
         "Prospectus").

               (ii) No order preventing or suspending the use of any Preliminary
         Prospectus has been issued by the Commission, and each Preliminary
         Prospectus, at the time of filing thereof, conformed in all material
         respects to the requirements of the Act and the rules and regulations
         of the Commission thereunder. The Preliminary Prospectus and the
         Prospectus, as each may be or have been amended or supplemented, as of
         its date and at all subsequent times, did not contain an untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary to make the statements therein, in
         the light of the circumstances under which they were made, not
         misleading; provided, however, that this representation and warranty
         shall not apply to any statements or omissions made in reliance upon
         and in conformity with information furnished in writing to the Company
         by an Underwriter through Goldman, Sachs & Co. expressly for use
         therein or by a Selling Stockholder expressly for use in the
         preparation of the answers therein to Items 7 and 11(m) of Form S-1.

               (iii) The Registration Statement conforms, and any further
         amendments or supplements to the Registration Statement will conform,
         in all material respects, to the requirements of the Act and the rules
         and regulations of the Commission thereunder, and does not and will
         not, as of the applicable effective date of the Registration Statement,
         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; provided, however, that this
         representation and warranty shall not apply to any statements or
         omissions made in reliance upon and in conformity with information
         furnished in writing to the Company by an Underwriter through Goldman,
         Sachs & Co. expressly for use therein or by a Selling Stockholder
         expressly for use in the preparation of the answers therein to Items 7
         and 11(m) of Form S-1.

               (iv) Neither the Company nor any of its subsidiaries has
         sustained since the date of the latest audited financial statements
         included in the Prospectus any material loss or interference with its
         business from fire, explosion, flood or other calamity, whether or not
         covered by insurance, or from any labor dispute or court or
         governmental action, order or decree, otherwise than as set forth or
         contemplated in the Prospectus; and, since the respective dates as of
         which information is given in the Registration Statement and the
         Prospectus, there has not been any change in the capital stock or
         long-term debt of the Company or any of its subsidiaries or any
         material adverse change, or any development involving a prospective
         material adverse change, in or affecting the management, financial







                                        2


         position, stockholders' equity or results of operations of the Company
         and its subsidiaries taken as a whole (each such change or resulting
         effect, a "Material Adverse Change" or "Material Adverse Effect," as
         the context requires), otherwise than as set forth in or contemplated
         by the Prospectus;

               (v) The Company and its subsidiaries have good and marketable
         title in fee simple to all real property and good and marketable title
         to all personal property owned by them, in each case free and clear of
         all liens, encumbrances and defects except such as are described in the
         Prospectus or such as do not materially and adversely affect the value
         of such property and do not materially interfere with the use made and
         proposed to be made of such property by the Company and its
         subsidiaries; and any real property and buildings held under lease by
         the Company and its subsidiaries are held by them under valid,
         subsisting and enforceable leases with such exceptions as are not
         material and do not materially interfere with the use made and proposed
         to be made of such property and buildings by the Company and its
         subsidiaries;

               (vi) The Company has been duly incorporated and is validly
         existing as a corporation in good standing under the laws of the State
         of Delaware, with full corporate power and authority to own its
         properties and conduct its business as described in the Prospectus, and
         has been duly qualified as a foreign corporation for the transaction of
         business and is in good standing under the laws of each other
         jurisdiction in which it owns or leases properties or conducts any
         business so as to require such qualification, except where the failure
         to do so would not result in a Material Adverse Effect; and each
         subsidiary of the Company has been duly incorporated and is validly
         existing as a corporation in good standing under the laws of its
         jurisdiction of incorporation;

               (vii) The Company has an authorized capitalization as set forth
         in the Prospectus under the caption "Capitalization" (other than
         subsequent issuances, if any, pursuant to the Company's employee
         benefit plans, or upon the exercise of outstanding options or warrants,
         if any), and all of the issued shares of capital stock of the Company
         have been duly authorized and validly issued, are fully paid and
         non-assessable and conform to the description of the Stock contained in
         the Prospectus; and all of the issued shares of capital stock of each
         subsidiary of the Company have been duly authorized and validly issued,
         are fully paid and non-assessable and (except for directors' qualifying
         shares and except as set forth in the Prospectus) are owned directly or
         indirectly by the Company, free and clear of all liens, encumbrances,
         equities or claims;

               (viii) The Shares to be issued and sold by the Company to the
         Underwriters hereunder have been duly authorized and, when issued and
         delivered against payment therefor as provided herein, will be validly
         issued and fully paid and non-assessable and will conform to the
         description of the Stock contained in the Prospectus;

               (ix) The issue and sale of the Shares to be sold by the Company
         and the compliance by the Company with all of the provisions of this
         Agreement and the consummation of the transactions herein contemplated
         will not conflict with or result in a breach or violation of any of the
         terms or provisions of, or constitute a default under, any indenture,
         mortgage, deed of trust, loan agreement or other agreement or
         instrument to which the Company or any of its subsidiaries is a party
         or by which the Company or any of its subsidiaries is bound or to which
         any of the property or assets of the Company or any of its subsidiaries
         is subject, except, in any such case, for such conflicts, breaches,
         violations or defaults which could reasonably be expected to result in
         a Material Adverse Effect, nor will such action result in any violation
         of the provisions of the Certificate of Incorporation or By-laws of the
         Company or any statute or any order, rule or regulation of any court or
         governmental agency or body having jurisdiction over the Company or any






                                        3


         of its subsidiaries or any of their properties; and no consent,
         approval, authorization, order, registration or qualification of or
         with any such court or governmental agency or body is required for the
         issue and sale of the Shares or the consummation by the Company of the
         transactions contemplated by this Agreement, except the registration
         under the Act of the Shares and such consents, approvals,
         authorizations, registrations or qualifications as may be required (A)
         under state securities or Blue Sky laws in connection with the purchase
         and distribution of the Shares by the Underwriters, (B) by the National
         Association of Securities Dealers, Inc., or (C) by the Nasdaq National
         Market;

               (x) Neither the Company nor any of its subsidiaries is (A) in
         violation of its Certificate of Incorporation or By-laws or (B) in
         default in the performance or observance of any material obligation,
         agreement, covenant or condition contained in any indenture, mortgage,
         deed of trust, loan agreement, lease or other agreement or instrument
         to which it is a party or by which it or any of its properties may be
         bound, except, with respect to clause (B), as otherwise disclosed in
         the Prospectus and except for such violations or defaults which could
         not reasonably be expected to result in a Material Adverse Effect;

               (xi) The statements set forth in the Prospectus under the caption
         "Description of Capital Stock", insofar as they purport to constitute a
         summary of the terms of the Stock, and under the caption
         "Underwriting", insofar as they purport to describe the provisions of
         the laws and documents referred to therein, are accurate, complete and
         fair;

               (xii) Other than as set forth in the Prospectus, there are no
         legal or governmental proceedings pending to which the Company or any
         of its subsidiaries is a party or of which any property of the Company
         or any of its subsidiaries is the subject which, if determined
         adversely to the Company or any of its subsidiaries, would individually
         or in the aggregate have a Material Adverse Effect; and, to the best of
         the Company's knowledge, no such proceedings are threatened or
         contemplated by governmental authorities or threatened by others;

               (xiii) The Company is not and, after giving effect to the
         offering and sale of the Shares, will not be an "investment company",
         as such term is defined in the Investment Company Act of 1940, as
         amended (the "Investment Company Act");

               (xiv) Arthur Andersen LLP, who have certified certain financial
         statements of the Company and its subsidiaries, are independent public
         accountants as required by the Act and the rules and regulations of the
         Commission thereunder;

               (xv) The Company has reviewed its operations and that of its
         subsidiaries and any third parties with which the Company or any of its
         subsidiaries has a material relationship to evaluate the extent to
         which the business or operations of the Company or any of its
         subsidiaries will be affected by the Year 2000 Problem. As a result of
         such review, the Company has no reason to believe, and does not
         believe, that the Year 2000 Problem will have a Material Adverse
         Effect. The "Year 2000 Problem" as used herein means any significant
         risk that computer hardware or software used in the receipt,
         transmission, processing, manipulation, storage, retrieval,
         retransmission or other utilization of data or in the operation of
         mechanical or electrical systems of any kind will not, in the case of
         dates or time periods occurring after December 31, 1999, function at
         least as effectively as in the case of dates or time periods occurring
         prior to January 1, 2000;

               (xvi) There are no persons with registration or other similar
         rights to have any equity or debt securities registered for sale under
         the Registration Statement or included in the offering contemplated by
         this Agreement, except for such rights as have been duly waived;




                                        4



               (xvii) The Company and each of its subsidiaries maintain a system
         of accounting controls sufficient to provide reasonable assurances that
         (i) transactions are executed in accordance with management's general
         or specific authorization; (ii) transactions are recorded as necessary
         to permit preparation of financial statements in conformity with
         generally accepted accounting principles as applied in the United
         States and to maintain accountability for assets; (iii) access to
         assets is permitted only in accordance with management's general or
         specific authorization; and (iv) the recorded accountability for assets
         is compared with existing assets at reasonable intervals and
         appropriate action is taken with respect to any differences;

               (xviii)The financial statements filed with the Commission as a
         part of the Registration Statement and included in the Prospectus
         present fairly the consolidated financial position of the Company and
         its subsidiaries as of and at the dates indicated and the results of
         their operations and cash flows for the periods specified. The
         supporting schedules included in the Registration Statement, if any,
         present fairly the information required to be stated therein. Such
         financial statements and supporting schedules have been prepared in
         conformity with generally accepted accounting principles as applied in
         the United States on a consistent basis throughout the periods
         involved, except as may be expressly stated in the related notes
         thereto. No other financial statements or supporting schedules are
         required to be included in the Registration Statement. The financial
         data set forth in the Prospectus under the captions "Prospectus
         Summary--Summary Selected Financial Data", "Selected Financial Data"
         and "Capitalization" fairly present the information set forth therein
         on a basis consistent with that of the audited financial statements
         contained in the Registration Statement;

               (xix) The Company and its consolidated subsidiaries have filed
         all necessary federal, state and foreign income and franchise tax
         returns or have properly requested extensions thereof and have paid all
         taxes required to be paid by any of them and, if due and payable, any
         related or similar assessment, fine or penalty levied against any of
         them, except where such failure could not reasonably result in a
         Material Adverse Effect. The Company has made adequate charges,
         accruals and reserves in the applicable financial statements referred
         to in Section 1(xviii) above in respect of all federal, state and
         foreign income and franchise taxes for all periods as to which the tax
         liability of the Company or any of its consolidated subsidiaries has
         not been finally determined. The Company is not aware of any tax
         deficiency that has been or might be asserted or threatened against the
         Company that could result in a Material Adverse Effect;

               (xx) Except as disclosed in the Prospectus, each of the Company
         and its subsidiaries owns or possesses adequate rights to use all
         patents, patent rights or licenses, inventions, collaborative research
         agreements, trade secrets, know-how, trademarks, service marks, trade
         names and copyrights and other intellectual property rights which are
         necessary to conduct its businesses as described in the Registration
         Statement and Prospectus; except as disclosed in the Prospectus, the
         expiration of any patents, patent rights, trade secrets, trademarks,
         service marks, trade names or copyrights would not result in a Material
         Adverse Effect that is not otherwise disclosed in the Prospectus; the
         Company has not received any notice of, and has no knowledge of, any
         infringement of or conflict with asserted rights of the Company by
         others with respect to any patent, patent rights, inventions, trade
         secrets, know-how, trademarks, service marks, trade names or
         copyrights; and the Company has not received any notice of, and has no
         knowledge of, any infringement of or conflict with asserted rights of
         others with respect to any patent, patent rights, inventions, trade
         secrets, know-how, trademarks, service marks, trade names or copyrights
         which, singly or in the aggregate, if the subject of an unfavorable





                                        5


         decision, ruling or finding, might have a Material Adverse Effect. To
         the Company's knowledge, there is no claim being made against the
         Company regarding patents, patent rights or licenses, inventions,
         collaborative research, trade secrets, know-how, trademarks, service
         marks, trade names or copyrights. The Company and its subsidiaries do
         not in the conduct of their business as now or proposed to be conducted
         as described in the Prospectus infringe or conflict with any right or
         patent of any third party, or any discovery, invention, product or
         process which is the subject of a patent application filed by any third
         party, known to the Company or any of its subsidiaries, which such
         infringement or conflict is reasonably likely to result in a Material
         Adverse Effect;

               (xxi) Each of the Company and its subsidiaries is insured by
         recognized, financially sound and reputable institutions with policies
         in such amounts and with such deductibles and covering such risks as
         are generally deemed adequate and customary for their businesses
         including, but not limited to, policies covering real and personal
         property owned or leased by the Company and its subsidiaries against
         theft, damage, destruction, acts of vandalism and earthquakes, general
         liability and Directors and Officers liability. The Company has no
         reason to believe that it or any subsidiary will not be able (i) to
         renew its existing insurance coverage as and when such policies expire
         or (ii) to obtain comparable coverage from similar institutions as may
         be necessary or appropriate to conduct its business as now conducted
         and at a cost that would not result in a Material Adverse Effect.
         Neither of the Company nor any subsidiary has been denied any insurance
         coverage which it has sought or for which it has applied; and

               (xxii) The Company and its subsidiaries and any "employee benefit
         plan" (as defined under the Employee Retirement Income Security Act of
         1974, as amended, and the regulations and published interpretations
         thereunder (collectively, "ERISA")) established or maintained by the
         Company, its subsidiaries or their "ERISA Affiliates" (as defined
         below) are in compliance in all material respects with ERISA, except
         where the failure to comply would not reasonably be expected to result
         in a Material Adverse Effect. "ERISA Affiliates" means, with respect to
         the Company or a subsidiary, any member of any group of organizations
         described in Sections 414(b),(c),(m) or (o) of the Internal Revenue
         Code of 1986, as amended, and the regulations and published
         interpretations thereunder (the "Code") of which the Company or such
         subsidiary is a member. No "reportable event" (as defined under ERISA)
         has occurred or is reasonably expected to occur with respect to any
         "employee benefit plan" established or maintained by the Company, its
         subsidiaries or any of their ERISA Affiliates. No "employee benefit
         plan" established or maintained by the Company, its subsidiaries or any
         of their ERISA Affiliates, if such "employee benefit plan" were
         terminated, would have any "amount of unfounded benefit liabilities"
         (as defined under ERISA). Neither the Company, its subsidiaries nor any
         of their ERISA Affiliates has incurred or reasonably expects to incur
         any liability under (i) Title IV of ERISA with respect to termination
         of, or withdrawal from, any "employee benefit plan" or (ii) Sections
         412, 4971, 4975 or 4980B of the Code. Each "employee benefit plan"
         established or maintained by the Company, its subsidiaries or any of
         their ERISA Affiliates that is intended to be qualified under Section
         401(a) of the Code is so qualified and nothing has occurred, whether by
         action or failure to act, which would cause the loss of such
         qualification.

         (b) Each of the Selling Stockholders severally represents and warrants
to, and agrees with, each of the Underwriters and the Company that:

         Stockholder hereunder and the compliance by such Selling Stockholder
         with all of the provisions of this Agreement, the Power of Attorney and
         the Custody Agreement and the consummation of the transactions herein
         and therein contemplated will not conflict with or result in a breach
         or violation of any of the terms or provisions of, or constitute a
         default under, any statute, indenture, mortgage, deed of trust, loan
         agreement or other agreement or instrument to which such Selling
         Stockholder is a party or by which such Selling Stockholder is bound or
         to which any of the Shares to be sold by the Selling Stockholder is

         Stockholder if such Selling Stockholder is a corporation, the
         partnership agreement of such Selling Stockholder if such Selling
         Stockholder is a partnership or any statute or any order, rule or

         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 of the
         Company to facilitate the sale or resale of the Shares;

               (vi) To the extent that any statements or omissions made in the
         Registration Statement, any Preliminary Prospectus, the Prospectus or
         any amendment or supplement thereto are made in reliance upon and in

         other applicable form or statement specified by Treasury Department
         regulations in lieu thereof);

               (viii) Certificates in negotiable form representing all of the
         Shares to be sold by such Selling Stockholder hereunder have been
         placed in custody under a Custody Agreement, in the form heretofore
         furnished to you (the "Custody Agreement"), duly executed and delivered
         by such Selling Stockholder to the Company, as custodian (the

         delivered a Power of Attorney, in the form heretofore furnished to you

         attorneys-in-fact (the "Attorneys-in-Fact") with authority to execute
         and deliver this Agreement on behalf of such Selling Stockholder, to
         determine the purchase price to be paid by the Underwriters to the
         Selling Stockholders as provided in Section 2 hereof, to authorize the
         delivery of the Shares to be sold by such Selling Stockholder hereunder
         and otherwise to act on behalf of such Selling Stockholder in
         connection with the transactions contemplated by this Agreement, the

         for such Selling Stockholder under the Custody Agreement are subject to
         the interests of the Underwriters hereunder; the arrangements made by
         such Selling Stockholder for such custody, and the appointment by such
         Selling Stockholder of the Attorneys-in-Fact by the Power of Attorney,
         are to that extent irrevocable; the obligations of the Selling
         Stockholders hereunder shall not be terminated by operation of law,
         whether by the death or incapacity of any individual Selling
         Stockholder or, in the case of an estate or trust, by the death or
         incapacity of any executor or trustee or the termination of such estate
         or trust, or in the case of a partnership or corporation, by the
         dissolution of such partnership or corporation, or by the occurrence of
         any other event; if any individual Selling Stockholder or any such
         executor or trustee should die or become incapacitated, or if any such
         estate or trust should be terminated, or if any such partnership or
         corporation should be dissolved, or if any other such event should
         occur, before the delivery of the Shares hereunder, certificates
         representing the Shares shall be delivered by or on behalf of the
         Selling Stockholders in accordance with the terms and conditions of
         this Agreement and of the Custody Agreements; and actions taken by the
         Attorneys-in-Fact pursuant to the Powers of Attorney shall be as valid
         as if such death, incapacity, termination, dissolution or other event
         had not occurred, regardless of whether or not the Custodian, the
         Attorneys-in-Fact, or any of them, shall have received notice of such
         death, incapacity, termination, dissolution or other event.

         2. Subject to the terms and conditions herein set forth, (a) the
Company and each of the Selling Stockholders agree, severally and not jointly,
to sell to each of the Underwriters, and each of the Underwriters agrees,







                                        8


severally and not jointly, to purchase from the Company and each of the Selling
Stockholders, at a purchase price per share of $.............., the number of
Firm Shares (to be adjusted by you so as to eliminate fractional shares)
determined by multiplying the aggregate number of Shares to be sold by the
Company and each of the Selling Stockholders as set forth opposite their
respective names in Schedule II-A hereto by a fraction, the numerator of which
is the aggregate number of Firm Shares to be purchased by such Underwriter as
set forth opposite the name of such Underwriter in Schedule I hereto and the
denominator of which is the aggregate number of Firm Shares to be purchased by
all of the Underwriters from the Company and all of the Selling Stockholders
hereunder and (b) in the event and to the extent that the Underwriters shall
exercise the election to purchase Optional Shares as provided below, each of the
Selling Stockholders listed on Schedule II-B agrees, severally and not jointly,
to sell to each of the Underwriters, and each of the Underwriters agrees,
severally and not jointly, to purchase from each of such Selling Stockholders,
at the purchase price per share set forth in clause (a) of this Section 2, that
portion of the number of Optional Shares as to which such election shall have
been exercised (to be adjusted by you so as to eliminate fractional shares)
determined by multiplying such number of Optional Shares by a fraction the
numerator of which is the maximum number of Optional Shares which such
Underwriter is entitled to purchase as set forth opposite the name of such
Underwriter in Schedule I hereto and the denominator of which is the maximum
number of Optional Shares that all of the Underwriters are entitled to purchase
hereunder.

         The Selling Stockholders listed on Schedule II-B, as and to the extent
indicated in Schedule II-B hereto, hereby grant, severally and not jointly, to
the Underwriters the right to purchase at their election up to an aggregate of
570,000 Optional Shares, at the purchase price per share set forth in the
paragraph above, for the sole purpose of covering sales of shares in excess of
the number of Firm Shares. Any such election to purchase Optional Shares shall
be made in proportion to the maximum number of Optional Shares to be sold by
each Selling Stockholder as set forth in Schedule II-B hereto. Any such election
to purchase Optional Shares may be exercised only by written notice from you to
the Attorneys-in-Fact, given within a period of 30 calendar days after the date
of this Agreement and setting forth the aggregate number of Optional Shares to
be purchased and the date on which such Optional Shares are to be delivered, as
determined by you but in no event earlier than the First Time of Delivery (as
defined in Section 4 hereof) or, unless you and the Attorneys-in-Fact otherwise
agree in writing, earlier than two or later than ten business days after the
date of such notice.

         3. Upon the authorization by you of the release of the Firm Shares, the
several Underwriters propose to offer the Firm Shares for sale upon the terms
and conditions set forth in the Prospectus.

         4. (a) The Shares to be purchased by each Underwriter hereunder, in
definitive form, and in such authorized denominations and registered in such
names as Goldman, Sachs & Co. may request upon at least forty-eight hours' prior
notice to the Company and the Selling Stockholders shall be delivered by or on
behalf of the Company and the Selling Stockholders to Goldman, Sachs & Co.,
through the facilities of the Depository Trust Company ("DTC"), for the account
of such Underwriter, against payment by or on behalf of such Underwriter of the
purchase price therefor by wire transfer of Federal (same-day) funds to the
account specified by the Company and the Custodian to Goldman, Sachs & Co. at
least forty-eight hours in advance. The Company will cause the certificates
representing the Shares to be made available for checking and packaging at least
twenty-four hours prior to the Time of Delivery (as defined below) with respect
thereto at the office of DTC or its designated custodian Goldman, Sachs & Co.,
85 Broad Street, New York, New York 10004 (the "Designated Office"). The time
and date of such delivery and payment shall be, with respect to the Firm Shares,





                                        9

Shares, or such other time and date as Goldman, Sachs & Co. the Selling
Stockholders may agree upon in writing. Such time and date for delivery of the
Firm Shares is herein called the "First Time of Delivery", such time and date
for delivery of the Optional Shares, if not the First Time of Delivery, is
herein called the "Second Time of Delivery", and each such time and date for
delivery is herein called a "Time of Delivery".

         (b) The documents to be delivered at each Time of Delivery by or on
behalf of the parties hereto pursuant to Section 7 hereof, including the cross
receipt for the Shares and any additional documents requested by the
Underwriters pursuant to Section 7(k) hereof, will be delivered at the offices
of Brobeck, Phleger & Harrison LLP, 1633 Broadway, New York, New York 10019 (the
"Closing Location"), and the Shares will be delivered at the Designated Office,
all at such Time of Delivery. A meeting will be held at the Closing Location at
 .......p.m., New York City time, on the New York Business Day next preceding
such Time of Delivery, at which meeting the final drafts of the documents to be

is required at any time prior to the expiration of nine months after the time of
issue of the Prospectus in connection with the offering or sale of the Shares
and if at such time any events shall have occurred as a result of which the
Prospectus as then amended or supplemented would include an untrue statement of
a material fact or omit to state any material fact necessary in order to make
the statements therein, in the light of the circumstances under which they were
made when such Prospectus is delivered, not misleading, or, if for any other
reason it shall be necessary during such period to amend or supplement the
Prospectus in order to comply with the Act, to notify you and upon your request
to prepare and furnish without charge to each Underwriter and to any dealer in
securities as many copies as you may from time to time reasonably request of an
amended Prospectus or a supplement to the Prospectus which will correct such
statement or omission or effect such compliance, and in case any Underwriter is
required to deliver a prospectus in connection with sales of any of the Shares
at any time nine months or more after the time of issue of the Prospectus, upon
your request but at the expense of such Underwriter, to prepare and deliver to

Annex II hereto throughout the remainder of the 90-day period;

         (f) To furnish to its stockholders as soon as practicable after the end

               information and statements contained in the Registration
               Statement and the Prospectus, such counsel has participated in
               conferences with certain officers and other representatives of
               the Company, its independent public accountants, the Underwriters
               and the Underwriters' counsel at which the contents of the

               requirements of the Act and the applicable rules and regulations
               thereunder; (ii) such counsel confirms that they have no reason
               to believe that the Registration Statement (other than the
               financial statements, including the notes and schedules thereto
               and the other financial data, included in the Registration
               Statement, as to which they need express no belief), at the time

               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; and (iii) such counsel confirms that they
               have no reason to believe that the Prospectus (other than the
               financial statements, including the notes and schedules thereto
               and the other financial data, included in the Prospectus, as to
               which they need express no belief), as of its date and on the
               date of such opinion, contained or contains any untrue statement
               of a material fact or omitted or omits to state a material fact
               necessary in order to make the statements therein, in light of
               the circumstances under which they were made, not misleading.

furnished to the Company by such Underwriter through Goldman, Sachs & Co.
expressly for use therein; and will reimburse the Company and each Selling
Stockholder for any legal or other expenses reasonably incurred by the Company
or such Selling Stockholder in connection with investigating or defending any
such action or claim as such expenses are incurred.



                                       18



         (d) Promptly after receipt by an indemnified party under subsection
(a), (b) or (c) above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection. In case any such
action shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party (who shall not,
except with the consent of the indemnified party, be counsel to the indemnifying
party), and, after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, the indemnifying party shall
not be liable to such indemnified party under such subsection for any legal
expenses of other counsel or any other expenses, in each case subsequently
incurred by such indemnified party, in connection with the defense thereof other
than reasonable costs of investigation. No indemnifying party shall, without the
written consent of the indemnified party, effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending or
threatened action or claim in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified party is an actual or
potential party to such action or claim) unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability arising out of such action 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.

         (e) If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a), (b) or (c) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by the Company and the Selling Stockholders on the
one hand and the Underwriters on the other from the offering of the Shares. If,
however, the allocation provided by the immediately preceding sentence is not
permitted by applicable law or if the indemnified party failed to give the
notice required under subsection (d) above, then each indemnifying party shall
contribute to such amount paid or payable by such indemnified party in such
proportion as is appropriate to reflect not only such relative benefits but also
the relative fault of the Company and the Selling Stockholders on the one hand
and the Underwriters on the other in connection with the statements or omissions
which resulted in such losses, claims, damages or liabilities (or actions in
respect thereof), as well as any other relevant equitable considerations. The
relative benefits received by the Company and the Selling Stockholders on the
one hand and the Underwriters on the other shall be deemed to be in the same
proportion as the total net proceeds from the offering (before deducting
expenses) received by the Company and the Selling Stockholders bear to the total
underwriting discounts and commissions received by the Underwriters, in each
case as set forth in the table on the cover page of the Prospectus. The relative
fault shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
or the Selling Stockholders on the one hand or the Underwriters on the other and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission. The Company, each of the
Selling Stockholders and the Underwriters agree that it would not be just and
equitable if contributions pursuant to this subsection (e) were determined by




                                       19


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 subsection (e). The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
in this subsection (e) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
subsection (e), no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Shares 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 such untrue or alleged untrue statement or omission or alleged
omission. Notwithstanding anything to the contrary set forth in this Section
8(e), no Selling Stockholder shall be required to contribute any amounts in
excess of the product of the number of Shares sold by such Selling Stockholder,
including Optional Shares, and the public offering price of the Shares as set
forth in the Prospectus. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations in this subsection (e) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

         (f) The obligations of the Company and the Selling Stockholders under
this Section 8 shall be in addition to any liability which the Company and the
respective Selling Stockholders may otherwise have and shall extend, upon the
same terms and conditions, to each person, if any, who controls any Underwriter
within the meaning of the Act; and the obligations of the Underwriters under
this Section 8 shall be in addition to any liability which the respective
Underwriters may otherwise have and shall extend, upon the same terms and
conditions, to each officer and director of the Company and to each person, if
any, who controls the Company or any Selling Stockholder within the meaning of
the Act.

         9. (a) If any Underwriter shall default in its obligation to purchase
the Shares which it has agreed to purchase hereunder at a Time of Delivery, you
may in your discretion arrange for you or another party or other parties to
purchase such Shares on the terms contained herein. If within thirty-six hours
after such default by any Underwriter you do not arrange for the purchase of
such Shares, then the Company and the Selling Stockholders shall be entitled to
a further period of thirty-six hours within which to procure another party or
other parties satisfactory to you to purchase such Shares on such terms. In the
event that, within the respective prescribed periods, you notify the Company and
the Selling Stockholders that you have so arranged for the purchase of such
Shares, or the Company and the Selling Stockholders notify you that they have so
arranged for the purchase of such Shares, you or the Company and the Selling
Stockholders shall have the right to postpone a Time of Delivery for a period of
not more than seven days, in order to effect whatever changes may thereby be
made necessary in the Registration Statement or the Prospectus, or in any other
documents or arrangements, and the Company agrees to file promptly any
amendments to the Registration Statement or the Prospectus which in your opinion
may thereby be made necessary. The term "Underwriter" as used in this Agreement
shall include any person substituted under this Section with like effect as if
such person had originally been a party to this Agreement with respect to such
Shares.

         (b) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company and
the Selling Stockholders as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased does not exceed one-eleventh of
the aggregate number of all the Shares to be purchased at such Time of Delivery,




                                       20



then the Company and the Selling Stockholders shall have the right to require
each non-defaulting Underwriter to purchase the number of Shares which such
Underwriter agreed to purchase hereunder at such Time of Delivery and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the number of Shares which such Underwriter agreed to purchase
hereunder) of the Shares of such defaulting Underwriter or Underwriters for
which such arrangements have not been made; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

         (c) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company and
the Selling Stockholders as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased exceeds one-eleventh of the
aggregate number of all of the Shares to be purchased at such Time of Delivery,
or if the Company and the Selling Stockholders shall not exercise the right
described in subsection (b) above to require non-defaulting Underwriters to
purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement
(or, with respect to the Second Time of Delivery, the obligations of the
Underwriters to purchase and of the Optional Selling Stockholders to sell the
Optional Shares) shall thereupon terminate, without liability on the part of any
non-defaulting Underwriter or the Company or the Selling Stockholders, except
for the expenses to be borne by the Company and the Selling Stockholders and the
Underwriters as provided in Section 6 hereof and the indemnity and contribution
agreements in Section 8 hereof; but nothing herein shall relieve a defaulting
Underwriter from liability for its default.

         10. The respective indemnities, agreements, representations, warranties
and other statements of the Company, the Selling Stockholders and the several
Underwriters, as set forth in this Agreement or made by or on behalf of them
severally, respectively, pursuant to this Agreement, shall remain in full force
and effect, regardless of any investigation (or any statement as to the results
thereof) made by or on behalf of any Underwriter or any controlling person of
any Underwriter, or the Company, or any of the Selling Stockholders, or any
officer or director or controlling person of the Company, or any controlling
person of any Selling Stockholder, and shall survive delivery of and payment for
the Shares.

         11. If this Agreement shall be terminated pursuant to Section 9 hereof,
neither the Company nor the Selling Stockholders shall then be under any
liability to any Underwriter except as provided in Sections 6 and 8 hereof; but,
if for any other reason any Shares are not delivered by or on behalf of the
Company and the Selling Stockholders as provided herein, the Company and each of
the Selling Stockholders severally pro rata (based on the number of Shares to be
sold by the Company and such Selling Stockholder hereunder) will reimburse the
Underwriters through you for all out-of-pocket expenses approved in writing by
you, including reasonable fees and disbursements of counsel, reasonably incurred
by the Underwriters in making preparations for the purchase, sale and delivery
of the Shares not so delivered, but the Company and the Selling Stockholders
shall then be under no further liability to any Underwriter in respect of the
Shares not so delivered except as provided in Sections 6 and 8 hereof.

         12. In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by Goldman, Sachs & Co. on behalf of you as the
representatives; and in all dealings with any Selling Stockholder hereunder, you
and the Company shall be entitled to act and rely upon any statement, request,
notice or agreement on behalf of such Selling Stockholder made or given by any
or all of the Attorneys-in-Fact for such Selling Stockholder.




                                       21



         All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of Goldman, Sachs &
Co., 32 Old Slip, 21st Floor, New York, New York 10005, Attention: Registration
Department; if to any Selling Stockholder shall be delivered or sent by mail,
telex or facsimile transmission to counsel for such Selling Stockholder at its
address set forth in Schedule II hereto; and if to the Company shall be
delivered or sent by mail, telex or facsimile transmission to the address of the
Company set forth in the Registration Statement, Attention: Secretary; provided,
however, that any notice to an Underwriter pursuant to Section 8(d) hereof shall
be delivered or sent by mail, telex or facsimile transmission to such
Underwriter at its address set forth in its Underwriters' Questionnaire or telex
constituting such Questionnaire, which address will be supplied to the Company
or the Selling Stockholders by you on request. Any such statements, requests,
notices or agreements shall take effect upon receipt thereof.

         13. This Agreement shall be binding upon, and inure solely to the
benefit of, the Underwriters, the Company and the Selling Stockholders and, to
the extent provided in Sections 8 and 10 hereof, the officers and directors of
the Company and each person who controls the Company, any Selling Stockholder or
any Underwriter, and their respective heirs, executors, administrators,
successors and assigns, and no other person shall acquire or have any right
under or by virtue of this Agreement. No purchaser of any of the Shares from any
Underwriter shall be deemed a successor or assign by reason merely of such
purchase.

         14. Time shall be of the essence of this Agreement. As used herein, the
term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

         15. This Agreement shall be governed by and construed in accordance
with the laws of the State of New York.

         16. This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such counterparts shall together constitute one and the same
instrument.

         If the foregoing is in accordance with your understanding, please sign
and return to us one for the Company and each of the Representatives plus one
for each counsel and the Custodian, if any, and upon the acceptance hereof by
you, on behalf of each of the Underwriters, this letter and such acceptance
hereof shall constitute a binding agreement among each of the Underwriters, the
Company and each of the Selling Stockholders. It is understood that your
acceptance of this letter on behalf of each of the Underwriters is pursuant to
the authority set forth in a form of Agreement among Underwriters, the form of
which shall be submitted to the Company and the Selling Stockholders for
examination, upon request, but without warranty on your part as to the authority
of the signers thereof.




                                       22


         Any person executing and delivering this Agreement as Attorney-in-Fact
for a Selling Stockholder represents by so doing that he has been duly appointed
as Attorney-in-Fact by such Selling Stockholder pursuant to a validly existing
and binding Power-of-Attorney which authorizes such Attorney-in-Fact to take
such action.


                                              Very truly yours,

         Pursuant to Section 7(d) of the Underwriting Agreement, the accountants
shall furnish letters to the Underwriters to the effect that:

               (i) They are independent certified public accountants with
         respect to the Company and its subsidiaries within the meaning of the
         Act and the applicable published rules and regulations thereunder;

               (ii) In their opinion, the financial statements and any
         supplementary financial information and schedules (and, if applicable,
         financial forecasts and/or pro forma financial information) examined by
         them and included in the Prospectus or the Registration Statement
         comply as to form in all material respects with the applicable
         accounting requirements of the Act and the related published rules and
         regulations thereunder; and, if applicable, they have made a review in
         accordance with standards established by the American Institute of
         Certified Public Accountants of the unaudited consolidated interim
         financial statements, selected financial data, pro forma financial
         information, financial forecasts and/or condensed financial statements
         derived from audited financial statements of the Company for the
         periods specified in such letter, as indicated in their reports
         thereon, copies of which have been separately furnished to the
         representatives of the Underwriters (the "Representatives");

               (iii) They have made a review in accordance with standards
         established by the American Institute of Certified Public Accountants
         of the unaudited condensed consolidated statements of income,
         consolidated balance sheets and consolidated statements of cash flows
         included in the Prospectus as indicated in their reports thereon copies
         of which have been separately furnished to the Representatives and on
         the basis of specified procedures including inquiries of officials of
         the Company who have responsibility for financial and accounting
         matters regarding whether the unaudited condensed consolidated
         financial statements referred to in paragraph (vi)(A)(i) below comply
         as to form in all material respects with the applicable accounting
         requirements of the Act and the related published rules and
         regulations, nothing came to their attention that caused them to
         believe that the unaudited condensed consolidated financial statements
         do not comply as to form in all material respects with the applicable
         accounting requirements of the Act and the related published rules and
         regulations;

               (iv) The unaudited selected financial information with respect to
         the consolidated results of operations and financial position of the
         Company for the five most recent fiscal years included in the
         Prospectus agrees with the corresponding amounts (after restatements
         where applicable) in the audited consolidated financial statements for
         such five fiscal years which were included or incorporated by reference
         in the Company's Annual Reports on Form 10-K for such fiscal years;

               (v) They have compared the information in the Prospectus under
         selected captions with the disclosure requirements of Regulation S-K
         and on the basis of limited procedures specified in such letter nothing
         came to their attention as a result of the foregoing procedures that
         caused them to believe that this information does not conform in all
         material respects with the disclosure requirements of Items 301, 302,
         402 and 503(d), respectively, of Regulation S-K;


                                      F-1



               (vi) On the basis of limited procedures, not constituting an
         examination in accordance with generally accepted auditing standards,
         consisting of a reading of the unaudited financial statements and other
         information referred to below, a reading of the latest available
         interim financial statements of the Company and its subsidiaries,
         inspection of the minute books of the Company and its subsidiaries
         since the date of the latest audited financial statements included in
         the Prospectus, inquiries of officials of the Company and its
         subsidiaries responsible for financial and accounting matters and such
         other inquiries and procedures as may be specified in such letter,
         nothing came to their attention that caused them to believe that:

                      (A) (i) the unaudited consolidated statements of income,
               consolidated balance sheets and consolidated statements of cash
               flows included in the Prospectus do not comply as to form in all
               material respects with the applicable accounting requirements of
               the Act and the related published rules and regulations, or (ii)
               any material modifications should be made to the unaudited
               condensed consolidated statements of income, consolidated balance
               sheets and consolidated statements of cash flows included in the
               Prospectus for them to be in conformity with generally accepted
               accounting principles;

                      (B) any other unaudited income statement data and balance
               sheet items included in the Prospectus do not agree with the
               corresponding items in the unaudited consolidated financial
               statements from which such data and items were derived, and any
               such unaudited data and items were not determined on a basis
               substantially consistent with the basis for the corresponding
               amounts in the audited consolidated financial statements included
               in the Prospectus;

                      (C) the unaudited financial statements which were not
               included in the Prospectus but from which were derived any
               unaudited condensed financial statements referred to in clause
               (A) and any unaudited income statement data and balance sheet
               items included in the Prospectus and referred to in clause (B)
               were not determined on a basis substantially consistent with the
               basis for the audited consolidated financial statements included
               in the Prospectus;

                      (D) any unaudited pro forma consolidated condensed
               financial statements included in the Prospectus do not comply as
               to form in all material respects with the applicable accounting
               requirements of the Act and the published rules and regulations
               thereunder or the pro forma adjustments have not been properly
               applied to the historical amounts in the compilation of those
               statements;

                      (E) as of a specified date not more than five days prior
               to the date of such letter, there have been any changes in the
               consolidated capital stock (other than issuances of capital stock
               upon exercise of options and stock appreciation rights, upon
               earn-outs of performance shares and upon conversions of
               convertible securities, in each case which were outstanding on
               the date of the latest financial statements included in the
               Prospectus) or any increase in the consolidated long-term debt of
               the Company and its subsidiaries, or any decreases in
               consolidated net current assets or stockholders' equity or other
               items specified by the Representatives, or any increases in any
               items specified by the Representatives, in each case as compared
               with amounts shown in the latest balance sheet included in the

               decreases which the Prospectus discloses have occurred or may
               occur or which are described in such letter; and

                      (F) for the period from the date of the latest financial
               statements included in the Prospectus to the specified date
               referred to in clause (E) there were any decreases in
               consolidated net revenues or operating profit or the total or per
               share amounts of consolidated net income or other items specified
               by the Representatives, or any increases in any items specified
               by the Representatives, in each case as compared with the
               comparable period of the preceding year and with any other period
               of corresponding length specified by the Representatives, except
               in each case for decreases or increases which the Prospectus
               discloses have occurred or may occur or which are described in
               such letter; and

               (vii) In addition to the examination referred to in their

         specified procedures, not constituting an examination in accordance
         with generally accepted auditing standards, with respect to certain
         amounts, percentages and financial information specified by the
         Representatives, which are derived from the general accounting records
