Ladies and Gentlemen:

        Genencor International, Inc., a Delaware corporation (the "Company"),
confirms its agreements with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner
& Smith Incorporated ("Merrill Lynch") 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, Salomon Smith Barney Inc., Chase Securities
Inc. and Credit Suisse First Boston Corporation are acting as representatives
(in such capacity, the "Representatives"), with respect to (i) the sale by the
Company and the purchase by the 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 to the Underwriters, acting severally and not jointly, of
the option described in Section 2(b) hereof to purchase all or any part of
1,050,000 additional shares of Common Stock to cover over-allotments, if any.
The aforesaid 7,000,000 shares of Common Stock (the "Initial Securities") to be
purchased by the Underwriters and all or any part of the 1,050,000 shares of
Common Stock subject to the option


<PAGE>   6

described in Section 2(b) hereof (the "Option Securities") are hereinafter
called, collectively, the "Securities."

        In connection with the execution and delivery of this Agreement and the
sale of the Securities hereunder, the Company has effected, or prior to the
Closing Time (as hereinafter defined) will effect, the following transactions:
(i) the filing of an amended and restated certificate of incorporation of the
Company with the Secretary of State of the State of Delaware (the "Filing");
(ii) the reverse stock split as described in the Prospectus (as hereinafter
defined) (the "Stock Split"); and (iii) the execution and delivery of the new
stockholder agreement among the Company, Eastman Chemical Company and Danisco
A/S substantially in the form previously furnished to the Representatives (the
"New Stockholder Agreement"). The Filing, the Stock Split and the execution and
effectiveness of the New Stockholder Agreement are hereinafter collectively
called the "Related Transactions".

        The Company understands 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 and the Underwriters agree that up to 550,000 shares of the
Initial Securities to be purchased by the Underwriters (the "Reserved
Securities") shall be reserved for sale by the Underwriters to certain eligible
employees and persons having business relationships with the Company, as part of
the distribution of the Securities by the Underwriters, subject to the terms of
this Agreement, the applicable rules, regulations and interpretations of the
National Association of Securities Dealers, Inc. (the "NASD") and all other
applicable laws, rules and regulations. To the extent that such Reserved
Securities are not orally confirmed for purchase by such eligible employees and
persons having business relationships with the Company by the end of the first
business day after the date of this Agreement, such Reserved Securities may be
offered to the public as part of the public offering contemplated hereby.

        The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-1 (No. 333-36452) 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
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. The information included in any such prospectus that
was omitted from such registration statement at the time it became effective
pursuant to paragraph (b) of Rule 430A is referred to as "Rule 430A
Information". Each prospectus used before such registration statement became
effective, and any prospectus that omitted the Rule 430A Information that was
used after



                                       2
<PAGE>   7

such effectiveness and prior to the execution and delivery 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 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 form of prospectus in
the form first furnished to the Underwriters for use in connection with the
offering of the Securities is herein called the "Prospectus". For purposes of
this Agreement, all references to the Registration Statement, any preliminary
prospectus, the Prospectus or any amendment or supplement thereto 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. 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 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 and the Prospectus and any
        preliminary prospectuses and any supplement thereto or prospectus
        wrapper prepared in connection therewith, at their respective times of
        issuance and at the Closing Time, complied and will comply in all
        material respects with any applicable laws or regulations of foreign
        jurisdictions in which the Prospectus and



                                       3
<PAGE>   8

        such preliminary prospectuses, as amended or supplemented, if
        applicable, are distributed in connection with the offer and sale of
        Reserved Securities. Neither of the Prospectus nor any amendments or
        supplements thereto (including any prospectus wrapper), at the time the
        Prospectus or any amendments or supplements thereto were 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. The
        representations and warranties in this subsection shall not apply to
        statements in or omissions from the Registration Statement or the
        Prospectus made in reliance upon and in conformity with information
        furnished to the Company in writing by any Underwriter through the
        Representatives expressly for use in the Registration Statement or the
        Prospectus.

             Each preliminary prospectus and the prospectuses 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, except that offering price range, share and related pricing
        information was omitted in the preliminary prospectus filed as part of
        the Registration Statement as originally filed, 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 Commission pursuant to EDGAR,
        except to the extent permitted by Regulation S-T.

             (ii) Independent Accountants. PricewaterhouseCoopers LLP 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, shareholders' 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.



                                       4

             (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, 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") has been
        duly organized and is validly existing as a corporation in good standing
        (where applicable) 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 (where applicable) 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; 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, equity or
        charge of any kind (collectively, "Liens"); and 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.
        The only Subsidiaries of the Company are the Subsidiaries listed on
        Exhibit 21 to the Registration Statement.

             (vii) Capitalization. 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 pursuant to this Agreement, pursuant to 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. The shares of
        issued and outstanding capital stock of the Company have been issued in
        compliance, in all material respects, with all federal and state
        securities laws. Except as disclosed in the Registration Statement or
        the Prospectus, as of the dates as to which such information is
        provided, there are no outstanding options or warrants to purchase, or
        any preemptive rights or other rights to subscribe for or to purchase,
        any securities or obligations convertible into, or any contracts or
        commitments to issue or sell, shares of the Company's capital stock or
        any such options, warrants, rights, convertible securities or
        obligations. The description of the Company's stock option plan and the
        options granted thereunder set forth in the Prospectus accurately and
        fairly describe, in all material respects, the information required to
        be shown with respect to such plan and options.

             (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, 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 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



                                       6
<PAGE>   11

        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. The
        execution, delivery and performance of this Agreement, the consummation
        of the transactions contemplated in this Agreement and in the
        Registration Statement (including each of the Related Transactions, 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
        under this Agreement 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 (i) 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, except for
        such violations that would not result in a Material Adverse Effect, or
        (ii) the provisions of the charter or by-laws of the Company or any of
        its subsidiaries. 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, which, in either case, would result in a Material
        Adverse Effect.

             (xii) Absence of Proceedings. Except as described in the
        Registration Statement or the Prospectus, 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 (in
        respect of which the Company or any of its subsidiaries has been served
        with process or otherwise has notice), or, to the knowledge of the
        Company, threatened, against or affecting the Company or any subsidiary,
        or to which the property of the Company or any subsidiary is subject,
        which is required to be disclosed in the Registration Statement, or
        which would result in a Material Adverse Effect, or which would
        materially and adversely affect the consummation of the transactions
        contemplated in this Agreement (including each of the Related
        Transactions) or the performance by the Company of its obligations
        hereunder; and the aggregate of all pending legal or



                                       7
<PAGE>   12

        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, would not result
        in a Material Adverse Effect.

             (xiii) Accuracy of Contract Descriptions. All of the descriptions
        of contracts or other documents contained in the Registration Statement
        and the Prospectus are accurate descriptions of such contracts or other
        documents in all material respects. 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 or 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, including, without limitation, all of the
        intellectual property described in the Prospectus as being owned or
        licensed by the Company and its subsidiaries (collectively,
        "Intellectual Property"), necessary to carry on the business now
        operated by them. Neither the Company nor any of its subsidiaries has
        received any notice or is otherwise aware of any infringement of or
        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, which infringement or
        conflict (if the subject of any unfavorable decision, ruling or finding)
        or invalidity or inadequacy, singly or in the aggregate, would result in
        a Material Adverse Effect.

             (xv) Patents and Patent Applications. The Company has provided to
        counsel for the Representatives a complete and correct list, dated March
        17, 2000, of all patents owned (the "Owned Patents") or in-licensed by
        the Company and its subsidiaries and all patent applications filed by or
        on behalf of the Company and its subsidiaries (the "Patent
        Applications"); all of the Owned Patents and Patent Applications have
        been duly registered with, filed in or issued by, as the case may be,
        the United States Patent and Trademark Office or other filing offices,
        domestic or foreign, to the extent necessary or desirable to ensure full
        protection under any applicable law or regulation, and such
        registrations, filings, issuances and other actions remain in full force
        and effect; to the knowledge of the Company, there is no patent or
        patent application of any person that conflicts with any Owned Patent,
        other than any such conflict that would not have a Material Adverse
        Effect. To the Company's knowledge, there are no unpaid maintenance fees
        relating to the Owned Patents; and no Owned Patent has lapsed and no
        Patent



                                       8
<PAGE>   13

        Application been abandoned, in either case, that is material to the
        business of the Company and its subsidiaries as currently conducted.

             (xvi) Trademarks and Trademark Applications. The Company has
        provided to counsel for the Representatives a complete and correct list,
        dated March 17, 2000, of all trademarks and service marks that are
        material to the business of the Company and its subsidiaries as
        currently conducted (the "Registered Marks") and owned by the Company
        and its subsidiaries and all trademarks and service marks applications
        that are material to the business of the Company and its subsidiaries as
        currently conducted (the "Applied Marks") and filed by or on behalf of
        the Company and its subsidiaries; all of the Registered Marks and
        Applied Marks have been duly registered with, filed in or issued by, as
        the case may be, the United States Patent and Trademark Office or other
        filing offices, domestic or foreign, to the extent necessary or
        desirable to ensure full protection under any applicable law or
        regulation, and such registrations, filings, issuances and other actions
        remain in full force and effect; the Company or a subsidiary of the
        Company is the sole and exclusive owner of all right, title and interest
        in the Registered Marks; there are no claims, actions or proceedings
        pending or, to the knowledge of the Company, threatened challenging the
        validity of any of the Registered Marks or the registration relating to
        any Applied Marks that, if adversely determined, would result in a
        Material Adverse Effect; and the Company has taken all reasonable steps
        to secure, protect, and maintain the Registered Marks and Applied Marks.

             (xvii) Employee and Customer Confidentiality. To the best of the
        Company's knowledge, (a) each current and former employee, each
        consultant and each customer who has access to proprietary information
        of the Company and its subsidiaries has executed a confidentiality
        agreement and (b) all such agreements are presently in effect and are
        enforceable.

             (xviii) 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 under this Agreement, in connection with the offering,
        issuance or sale of the Securities under this Agreement or the
        consummation of the transactions contemplated by this Agreement
        (including each of the Related Transactions), except (i) such as have
        been already completed or obtained or, in the case of the Related
        Transactions, will be completed or obtained prior to the Closing Time or
        as may be required under the 1933 Act or the 1933 Act Regulations and
        state securities laws and (ii) such as have been obtained under the laws
        and regulations of jurisdictions outside the United States in which the
        Reserved Securities are offered.

             (xix) 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, including without limitation, the U.S. Food and Drug
        Administration ("FDA"), the United States Environmental Protection
        Agency ("EPA") and the United States Department of Agriculture ("USDA"),
        necessary to conduct the business now operated by them; the Company and
        its subsidiaries are in compliance with the terms and conditions of all
        such Governmental Licenses and all applicable rules of the FDA, EPA and
        USDA, except where the failure so to comply would not result in a
        Material Adverse Effect; all of the Governmental Licenses are valid and
        in full force and effect, except where the invalidity of such
        Governmental Licenses or the failure of such Governmental Licenses to be
        in full force and effect would not result in 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 finding, would result in a
        Material Adverse Effect.

             (xx) Title to Property. The Company and its subsidiaries have good
        and marketable title to all material real property owned by the Company
        and its subsidiaries and good title to all other material properties
        owned by them, in each case, free and clear of all mortgages, pledges,

        property and do not interfere with the use made and proposed to be made
        of such property by the Company or any of its subsidiaries; 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 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,
        except for any such claim that would not result in a Material Adverse
        Effect.

             (xxi) 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 Prospectus

                                       10
<PAGE>   15

             (xxii) Environmental Laws. Except as described in the Registration
        Statement or the Prospectus and except as would not, singly and 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, policy or
        rule of common law or any judicial or administrative interpretation
        thereof, including any judicial or administrative order, consent, decree
        or judgment, relating to pollution or protection of human health, the
        environment (including, without limitation, ambient air, surface water,
        groundwater, land surface or subsurface strata) or wildlife, including,
        without limitation, laws and regulations relating to the release or
        threatened release of chemicals, pollutants, contaminants, wastes, toxic
        substances, hazardous substances, petroleum or petroleum products

        distribution, use, treatment, storage, disposal, transport or handling
        of Hazardous Materials (collectively, "Environmental Laws"), (B) the

        approvals required under any applicable Environmental Laws and are each
        in compliance with their requirements, (C) there are no pending or
        threatened administrative, regulatory or judicial actions, suits,
        demands, demand letters, claims, liens, notices of noncompliance or
        violation, investigation or proceedings relating to any Environmental
        Law against the Company or any of its subsidiaries and (D) there are no
        events or circumstances that would reasonably be expected to form the
        basis of an order for clean-up or remediation, or an action, suit or
        proceeding by any private party or governmental body or agency, against
        or affecting the Company or any of its subsidiaries relating to
        Hazardous Materials or any Environmental Laws.

             (xxiii) Insurance. The Company and its subsidiaries are insured by
        insurers of recognized financial responsibility against such losses and
        risks and in such amounts as are prudent and customary in the businesses
        in which they are engaged; and the Company does not have any reason to
        believe that it or any of its subsidiaries will not be able to renew
        their existing insurance coverage as and when such coverage expires or
        to obtain similar coverage from similar insurers as may be necessary to
        continue their operations, except where the failure to renew or maintain
        such coverage would not result in a Material Adverse Effect.

             (xxiv) Tax Returns and Payment of Taxes. The Company and its
        subsidiaries have timely filed all federal, state, local and foreign tax
        returns that are required to be filed or have duly requested extensions
        thereof and all such tax returns are true, correct and complete, except
        to the extent that any failure to file or request an extension, or any
        incorrectness, would not result in a Material Adverse Effect. The
        Company and its subsidiaries have timely paid all taxes shown as due on
        such filed tax returns (including any related assessments, fines or
        penalties), except to the extent that any such taxes are being contested
        in good



                                       11
<PAGE>   16

        faith and by appropriate proceedings, or to the extent that any failure
        to pay would not result in a Material Adverse Effect; and adequate
        charges, accruals and reserves have been provided for in the financial
        statements referred to in Section 1(a)(iv) above in accordance with GAAP
        in respect of all Federal, state, local and foreign taxes for all
        periods as to which the tax liability of the Company and its
        subsidiaries has not been finally determined or remains open to
        examination by applicable taxing authorities. Neither the Company nor
        any of its subsidiaries is a "United States real property holding
        corporation" within the meaning of Section 897(c)(2) of the Internal
        Revenue Code of 1986, as amended.

             (xxv) No Stabilization or Manipulation. Neither the Company nor, to
        the best of its knowledge, any of its directors, officers or affiliates
        has taken or will take, directly or indirectly, any action designed to,
        or that would be reasonably expected to, cause or result in
        stabilization or manipulation of the price of the Securities in
        violation of Regulation M under the Securities Exchange Act of 1934, as
        amended (the "1934 Act").

             (xxvi) Registration Rights. There are no persons with registration
        rights or other similar rights to have any securities registered

        Registration Statement or the Prospectus, otherwise registered by the
        Company under the 1933 Act.

             (xxvii) Certain Relationships. There is no relationship, direct or
        indirect, between or among the Company or any of its affiliates on the
        one hand and any director, officer, stockholder, customer or supplier of
        any of them on the other hand, which is required by the 1933 Act or the
        1933 Act Regulations to be described in the Registration Statement and
        the Prospectus that is not so described or is not described as required.

             (xxviii) Statistical and Market Data. The statistical and
        market-related data included in the Prospectus are derived from sources
        that the Company reasonably and in good faith believes to be accurate,
        reasonable and reliable and such data agree with the sources from which
        it was derived.

             (xxix) Accounting and other Controls. The Company has established a
        system of internal accounting controls sufficient to provide reasonable
        assurances that (i) transactions were, are and will be executed in
        accordance with management's general or specific authorization; (ii)

        preparation of financial statements in conformity with GAAP and to
        maintain accountability for assets; (iii) access to assets was, is and
        will be permitted only in accordance with a management's general or
        specific authorizations; and (iv) the recorded accountability for assets



                                       12

        was, is and will be compared with existing assets at reasonable
        intervals and appropriate action was, is and will be taken with respect
        to any differences.

             (xxx) Related Transactions. Each of the Related Transactions has
        been duly and validly authorized by all necessary corporate action of
        the Company's stockholders and board of directors.

        (b) Officer's Certificates. Any certificate signed by any officer of
the Company or any of its subsidiaries delivered to Merrill Lynch, 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.

        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 B, 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.

        (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 hereby grants an option to the Underwriters, severally
and not jointly, to purchase up to an additional 1,050,000 shares of Common
Stock at the price per share set forth in Schedule B, 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 Merrill Lynch to the
Company 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 for the
Option Securities (a "Date of Delivery") shall be determined by Merrill Lynch,
but shall not be later than three (four, if the exercise of the option occurs
after 4:30 p.m. (Eastern time) on any given day) 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, 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



                                       13
<PAGE>   18

Underwriter bears to the total number of Initial Securities, subject in each
case to such adjustments as Merrill Lynch in its 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 Latham
& Watkins, 135 Commonwealth Drive, Menlo Park, CA 94025, or at such other place
as shall be agreed upon by Merrill Lynch and the Company, at 9:00 A.M. (Eastern
time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern time)
on any given day) business day after the date hereof (unless postponed in
accordance with the provisions of Section 10), or such other time not later than
ten business days after such date as shall be agreed upon by Merrill Lynch 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 Merrill Lynch and the
Company, on each Date of Delivery as specified in the notice from Merrill Lynch
to the Company.

        Payment shall be made to the Company by wire transfer of immediately
available funds to the bank account designated by the Company 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 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
and will notify Merrill Lynch 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 Merrill Lynch notice of
its intention to file or prepare any amendment to the Registration Statement
(including any filing under Rule 462(b)), 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 Merrill Lynch 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 such document to
which Merrill Lynch 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 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.



                                       15
<PAGE>   20

        (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 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
(domestic or foreign) as Merrill Lynch may reasonably 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



                                       16
<PAGE>   21

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.

        (h) Use of Proceeds. The Company will use the net proceeds received by
it from the sale of the Securities in 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
lend, transfer or dispose of, directly or indirectly, any share of Common Stock
or any securities convertible into, exercisable or exchangeable for or repayable
with 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 under this Agreement, (B) any shares of Common Stock issued by the Company
upon the exercise of an option or the conversion of a security outstanding on
the date hereof and referred to in the Prospectus, (C) any shares of Common
Stock issued or options to purchase Common Stock granted pursuant to the stock
option plans of the Company referred to in the Prospectus, (D) the filing of any

Company's stock option plans described in the Prospectus and (E) any option or
warrant to purchase shares of Common Stock or shares of Common Stock issued or
sold in connection with an acquisition by the Company and the filing of any
registration statement on Form S-4 in connection therewith as long as all
executive officers, directors and other affiliates of the person being acquired
who will receive shares in the acquisition



                                       17
<PAGE>   22

have agreed in writing to be bound by the obligations and restrictions of the
foregoing sentence of this Section 3(j).

        (k) Reporting Requirements. The Company, during the period when the
Prospectus as 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.

        (l) Compliance with NASD Rules. The Company hereby agrees that it will
ensure that the Reserved Securities will be restricted if and as required by the
NASD or the NASD rules from sale, transfer, assignment, pledge or hypothecation
for a period of three months following the date of this Agreement. The
Underwriters will notify the Company as to which persons will need to be so
restricted. At the request of the Underwriters, the Company will direct the
transfer agent to place a stop transfer restriction upon such securities for
such period of time. Should the Company release, or seek to release, from such
restrictions any of the Reserved Securities, the Company agrees to reimburse the
Underwriters for any reasonable expenses (including, without limitation, legal
expenses) they incur in connection with such release.

        SECTION 4. Payment of Expenses.

        Information, 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, arising out of (A) the violation of any
        applicable laws or regulations of foreign jurisdictions where Reserved
        Securities have been offered and (B) any untrue statement or alleged
        untrue statement of a material fact included in the supplement or
        prospectus wrapper material distributed in any jurisdiction in
        connection with the reservation and sale of the Reserved Securities to
        employees and persons having business relationships with the Company or
        any omission or alleged omission therefrom of a material fact necessary
        to make the statements therein, when considered in conjunction with the
        Prospectus or preliminary prospectuses, not misleading;

             (iii) 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 or in connection with any
        violation of the nature referred to in Section 6(a)(ii)(A) hereof;
        provided that (subject to Section 6(d) below) any such settlement is
        effected with the written consent of the Company; and

             (iv) 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 or in connection with any violation of the nature
        referred to in Section 6(a)(ii)(A) hereof, to the extent that any such
        expense is not paid under (i), (ii) or (iii) above;



                                       23
<PAGE>   28

provided, however, that this indemnity agreement shall not 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 the Representatives expressly for use in the Registration
Statement (or any amendment thereto), including the Rule 430A Information, or
any preliminary prospectus or the Prospectus (or any amendment or supplement
thereto).

        (b) Indemnification of Company and Directors and Officers. 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 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, 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 the Representatives 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 an 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. 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



                                       24
<PAGE>   29

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 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)(iii) 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.

        (e) Indemnification for Reserved Securities. In connection with the
offer and sale of the Reserved Securities, the Company agrees, promptly upon a
request in writing, to indemnify and hold harmless the Underwriters from and
against any and all losses, liabilities, claims, damages and expenses incurred
by them as a result of the failure of the employees and persons having business
relationships with the Company to pay for and accept delivery of Reserved
Securities which, by the end of the first business day following the date of
this Agreement, were subject to a properly confirmed agreement to purchase.

        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 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 on the one hand and of the Underwriters on the
other hand in connection with the statements or omissions, or in connection with
any violation of the nature referred to in Section 6(a)(ii)(A) hereof, which
resulted in such losses, liabilities, claims, damages or expenses, as well as
any other relevant equitable considerations.



                                       25
<PAGE>   30

        The relative benefits received by the Company 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 total underwriting discount received by the Underwriters, in each case
as set forth on the cover of the Prospectus bear to the aggregate initial public
offering price of the Securities as set forth on such cover.

        The relative fault of the Company 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 by the Underwriters and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission or any violation of the nature referred to in Section
6(a)(ii)(A) hereof.

        The Company 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.

        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



                                       26
<PAGE>   31

person, if any, who controls the Company 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. 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.

        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 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, and shall
survive delivery of the Securities to the Underwriters.

        SECTION 9. Termination of Agreement.

        (a) Termination; General. The Representatives may terminate this
Agreement, by notice to the Company, 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 NASD 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



                                       27
<PAGE>   32

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 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 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. 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 at North Tower, World
Financial Center, New York, New York 10281-1201, attention of Syndicate
Operations; and notices to the Company shall be directed to them at 925 Page
Mill Road, Palo Alto, California 94304, attention of Stuart L. Melton, Senior
Vice President of Commercial and Legal Affairs.

        SECTION 12. Parties. This Agreement shall each inure to the benefit of
and be binding upon the Underwriters, the Company 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 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 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 13. GOVERNING LAW AND TIME. THIS AGREEMENT SHALL BE CONSTRUED
AND ENFORCED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW
YORK (WITHOUT GIVING EFFECT TO ITS PRINCIPLES OR RULES OF CONFLICT OF LAWS TO
THE EXTENT SUCH PRINCIPLES OR RULES WOULD REQUIRE OR PERMIT THE APPLICATION OF
THE LAWS OF ANOTHER JURISDICTION). SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY
TIME.

        SECTION 14. Effect of Headings. The Article and Section headings herein
and the Table of Contents are for convenience only and shall not affect the
construction hereof.

                      FORM OF OPINION OF COMPANY'S COUNSEL
                           TO BE DELIVERED PURSUANT TO
                                  SECTION 5(b)


             (i) The Company has been duly incorporated and is validly existing
as a corporation in good standing under the laws of the State of Delaware.

             (ii) The Company has corporate power and corporate 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 the
Purchase Agreement.

             (iii) Based solely on certificates from the Secretaries of State of
the States of California, New York, Indiana and Illinois and Iowa, the Company
is duly qualified as a foreign corporation to transact business and is in good
standing in the states of California, New York, Indiana, Illinois and Iowa.

             (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 pursuant to the
Purchase Agreement or pursuant to agreements or employee benefit plans referred
to in the Prospectus or pursuant to the exercise of 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 to our knowledge 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 and sale to the Underwriters
pursuant to the Purchase Agreement and, when issued and delivered by the Company
pursuant to the Purchase Agreement against payment of the consideration set
forth in the Purchase Agreement, 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; and under the DGCL no holder of the
Securities is or will be subject to personal liability for the debts and
obligations of the Company as a result of its status as a stockholder, except as
any stockholder may be liable by reason of its own conduct or acts.

             (vi) The issuance and sale of the Securities are not subject to the
preemptive or other similar rights of any securityholder of the Company arising
under the DGCL, any federal, New York or California law, statute, rule or
regulation or the



                                      A-1
<PAGE>   39

certificate of incorporation or bylaws of the Company or, to our knowledge,
under any agreement or instrument to which the Company is a party.

             (vii) The Purchase Agreement has been duly authorized, executed and
delivered by the Company.

             (viii) 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 our
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 our knowledge, no proceedings for that purpose have been
instituted or are pending or are threatened by the Commission.

             (ix) The Registration Statement, including any Rule 462(b)
Registration Statement and the Rule 430A Information, as applicable, the
Prospectus, and each amendment or supplement to the Registration Statement and
the 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 we need express no opinion) complied as to form in all
material respects with the requirements of the 1933 Act and the 1933 Act
Regulations.

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

             (xi) To our knowledge, 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 threatened against or affecting the
Company or any subsidiary, or to which the property of the Company or any
subsidiary is subject, which is required to be disclosed in the Registration
Statement (other than as disclosed therein).

             (xii) The description of the new stockholders agreement in the
Prospectus under "Certain Transactions-Agreements with Significant Stockholders"
and the information under "Description of Capital Stock" and "United States
Federal Tax Consideration for Non-U.S. Holders" and in the Registration
Statement under Items 14 and 15, to the extent that such description and
information constitute summaries of legal matters under federal or California
law or the DGCL, agreements described therein or the Company's certificate of
incorporation and by-laws, are accurate in all material respects.

             (xiii) No filing with, or authorization, approval, consent,
license, order, registration, qualification or decree of, any federal, New York
or California court or



                                      A-2

governmental authority or agency or under the DGCL (other than those which have
been obtained, or as may be required under state securities or blue sky laws, as
to which we need express no opinion) is required by or on behalf of the Company
for the due authorization, execution and delivery of the Purchase Agreement by
the Company, the offering, issuance, sale or delivery of the Securities by the
Company under the Purchase Agreement or the consummation by the Company of each
of the Related Transactions.

             (xiv) The execution, delivery and performance of the Purchase
Agreement by the Company and the consummation of the Related Transactions do
not, as of the date of the opinion, (i) violate the provisions of the Company's
certificate of incorporation or bylaws, (ii) result in the breach of or a
default under any of the agreements filed as exhibits to the Registration
Statement (except for such breaches or defaults as would not have a Material
Adverse Effect), (iii) result in the breach of or a default under any court or
administrative order, writ, judgment or decree specifically directed to the
Company and identified to us by an officer of the Company (except for such
breaches or defaults as would not have a Material Adverse Effect), or (iv)
violate any federal, New York or California statute, rule or regulation, or any
provision of the DGCL, applicable to the Company.

             (xv) To our knowledge, there are no persons with registration
rights to have any securities registered pursuant to the Registration Statement
or, except as described in the Registration Statement or the Prospectus,
otherwise registered by the Company under the 1933 Act.

             (xvi) The Company is not and, after giving effect to the offering
and sale of the Securities, will not be an "investment company" as such term is
defined in the 1940 Act.

        We have participated in conferences with officers and other
representatives of the Company, representatives of the independent public
accountants for the Company and your representatives, at which the contents of
the Registration Statement and the Prospectus and any supplements or amendments
thereto, and related matters were discussed and, although we are not passing
upon, and do not assume any responsibility for, the accuracy, completeness or
fairness of the statements contained in the Registration Statement or the
Prospectus and have not made any independent check or verification thereof, and
any supplements or amendments thereto, based on such participation, no facts
came to our attention that lead us to believe that the Registration Statement or
any amendment thereto, including the Rule 430A Information (except for financial
statements and schedules and other financial data included therein or omitted
therefrom, as to which we 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



                                      A-3

(except for financial statements and schedules and other financial data included
therein or omitted therefrom, as to which we need make no statement), at the
time the Prospectus were 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. 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).

                       FORM OF OPINION OF STUART L. MELTON
                           TO BE DELIVERED PURSUANT TO
                                  SECTION 5(b)




        (i) To my knowledge, the Company and its Subsidiaries have obtained such
licenses, permits, approvals and authorizations required by the appropriate
federal, state, local or foreign regulatory agencies or bodies that are
necessary for the conduct of the businesses of the Company and its Subsidiaries
as they are currently conducted and described in the Prospectus and, to my
knowledge, such authorizations are in full force and effect, except where the
failure to have licenses, permit, approvals or such authorizations would not
result in a Material Adverse Effect.

        (ii) To my knowledge, 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 threatened against the Company or any
subsidiary, or to which the property of the Company or any subsidiary is
subject, which might reasonably be expected to result in a Material Adverse
Effect.

        (iii) The information in the Prospectus under "Business -- Regulatory
Environment" and "Business -- Legal Proceedings," to the extent it constitutes
matters of law, summaries of legal matters or legal proceedings, or legal
conclusions, has been reviewed by me and is correct in all material respects.

        In rendering such opinion, such counsel may rely, as to matters of fact
(but not as to legal conclusions), to the extent he deems proper, on the
certificates of responsible officers of the Company and public officials. 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
opinions, including without limitation, the Legal Opinion Accord of the ABA
Section of Business Law (1991).

                          FORM OF OPINION OF COMPANY'S
                          INTELLECTUAL PROPERTY COUNSEL
                           TO BE DELIVERED PURSUANT TO
                                  SECTION 5(b)


             (i) Based upon a review of patent applications identified in (iii)
below and discussions with in-house counsel of the Company, in our opinion the
Company and its Subsidiaries own or possess or can acquire on commercially
reasonable terms all patents necessary for the businesses now operated by them,
except where the failure to own or possess or otherwise be able to acquire such
patents would not result in a Material Adverse Effect.

             (ii) Based upon a review of third party rights made known to us,
discussions with in-house counsel of the Company and opinions of outside counsel
made available to us, we are not aware of any valid United States or foreign
patent that, in our opinion, is or would be infringed by the activities of the
Company or its Subsidiaries in the development, manufacture, use or sale of any
presently commercialized product or product in stage 4 development, except where
any such infringements would not result in a Material Adverse Effect.

             (iii) We have reviewed representative patent applications of the
Company identified by in-house counsel which claim technology described as
patented and/or proprietary in the Registration Statement under "Business -- Our
Technology Platforms," "Business -- Products and Product Development -- Products
Under Development" and "Business -- Proprietary Rights" in the Prospectus and,
in our opinion, based on our review of the representative patent applications
and discussions with in-house counsel of the Company, the Company follows
standardized practices which strongly suggest that the Company's patent
applications have been properly prepared and filed, are being diligently pursued
by the Company, and that the inventions described in the Company's patent
applications are owned by, have been assigned to or are licensed to the Company
or its Subsidiaries.

             (iv) Based upon a review of third-party rights known to us by
in-house counsel of the Company, discussions with in-house counsel of the
Company and opinions of outside counsel made available to us, no party or
individual has any right or claim in any of the inventions, patents or patent
applications of the Company and its Subsidiaries, which claim technology
identified as patented and/or proprietary in the Registration Statement under
"Business -- Our Technology Platforms," "Business -- Products and Product
Development -- Products Under Development and "Business -- Proprietary Rights"
in the Prospectus that would result in a Material Adverse Effect.

<PAGE>   44

             (v) Based upon a review of third-party rights known to us by
in-house counsel of the Company, discussions with in-house counsel of the
Company and opinions of outside counsel made available to us, neither the
Company nor any of its Subsidiaries is infringing or otherwise violating any
patents of others, and there are no infringements by others of any of the
Company's or its Subsidiaries' patents where infringement or violation would
result in a Material Adverse Effect. Based upon a review of third-party rights
known to us by in-house counsel of the Company, discussions with in-house
counsel of the Company and opinions of outside counsel made available to us, the
Company and its Subsidiaries have not received any notice of patent infringement
where such infringement or conflict would result in a Material Adverse Effect.

             (vi) We know of no legal or governmental proceedings that are
pending or, to our knowledge, that are threatened, relating to any Intellectual
Property, except (A) as disclosed in the Prospectus or (B) which, if the subject
of an unfavorable decision, ruling or finding, would not result in a Material
Adverse Effect.

        We are generally familiar with the Intellectual Property used by the
Company and its Subsidiaries in their business and the manner of such use and we
have reviewed the Prospectus, including the portions of the Prospectus
describing or referring to any Intellectual Property (collectively, the
"Intellectual Property Disclosure").

        Nothing has come to our attention that would lead us to believe that the
Intellectual Property Disclosure in the Registration Statement or any amendment
thereto, at the time the 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 Intellectual Property Disclosure
in the Prospectus or any amendment or supplement thereto, 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. 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).
