Ladies and Gentlemen:

Captiva Software Corporation, a Delaware corporation (the “Company”), proposes to sell to the several underwriters (the “Underwriters”) named in Schedule I hereto for which you are acting as representatives (the “Representatives”) an aggregate of 2,500,000 shares of the Company’s Common Stock, $0.001 par value (the “Firm Shares”). The respective numbers of Firm Shares to be so purchased by the several Underwriters are set forth opposite their names in Schedule I hereto. The Company also proposes to sell at the Underwriters’ option an aggregate of up to 375,000 additional shares of the Company’s Common Stock (the “Option Shares”) as set forth below.

As the Representatives, you have advised the Company (a) that you are authorized to enter into this Agreement on behalf of the several Underwriters, and (b) that the several Underwriters are willing, acting severally and not jointly, to purchase the numbers of Firm Shares set forth opposite their respective names in Schedule I, plus their pro rata portion of the Option Shares if you elect to exercise the over-allotment option in whole or in part for the accounts of the several Underwriters. The Firm Shares and the Option Shares (to the extent the aforementioned option is exercised) are herein collectively called the “Shares.”

¹ Plus an option to purchase up to 375,000 additional shares to cover over-allotments.

In consideration of the mutual agreements contained herein and of the interests of the parties in the transactions contemplated hereby, the parties hereto agree as follows:

1. Representations and Warranties of the Company.

The Company represents and warrants to each of the Underwriters as follows:

(a) A registration statement on Form S-3 (File No. 333-114415) with respect to the Shares has been prepared by the Company in conformity with the requirements of the Securities Act of 1933, as amended (the “Act”), and the Rules and Regulations (the “Rules and Regulations”) of the Securities and Exchange Commission (the “Commission”) thereunder and has been filed with the Commission. The Company has complied with the conditions for the use of Form S-3. Copies of such registration statement, including any amendments thereto, the preliminary prospectuses (meeting the requirements of the Rules and Regulations) contained therein and the exhibits, financial statements and schedules, as finally amended and revised, have heretofore been delivered by the Company to you. Such registration statement, together with any registration statement filed by the Company pursuant to Rule 462(b) of the Act, herein referred to as the “Registration Statement,” which shall be deemed to include all information omitted therefrom in reliance upon Rule 430A and contained in the Prospectus referred to below, has become effective under the Act and no post-effective amendment to the Registration Statement has been filed as of the date of this Agreement. “Prospectus” means the form of prospectus first filed with the Commission pursuant to Rule 424(b). Each preliminary prospectus included in the Registration Statement prior to the time it becomes effective is herein referred to as a “Preliminary Prospectus.”

(b) The Commission has not issued an order preventing or suspending the use of any Prospectus relating to the proposed offering of the Shares nor instituted proceedings for that purpose. The Registration Statement contains, and the Prospectus and any amendments or supplements thereto will contain, all statements that are required to be stated or incorporated by reference therein by, and will conform to, the requirements of the Act and the Rules and Regulations. The Registration Statement and any amendments thereto do not contain, and will not contain, any untrue statement of a material fact and do not omit, and will not omit, to state any material fact required to be stated therein or necessary to make the statements therein not misleading. The Prospectus and any amendments and supplements thereto do not contain, and will not contain, any untrue statement of a material fact; and do not omit, and will not omit, to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company makes no representations or warranties as to information contained in or omitted from the Registration Statement or the Prospectus, or any such amendment or supplement, in reliance upon, and in conformity with, written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for use in the preparation thereof. There are no contracts or documents that are required to be filed as exhibits to the Registration Statement or described in the Registration Statement or the Prospectus that are not so filed or described as required, and such contracts and documents as are summarized in the Registration Statement or the Prospectus are fairly summarized in all material respects.

(c) This Agreement has been duly authorized, executed and delivered by the Company, and constitutes a valid, legal and binding obligation of the Company, enforceable in

accordance with its terms, except as rights to indemnity hereunder may be limited by federal or state securities laws and except as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting the rights of creditors generally, and subject to general principles of equity. The Company has full power and authority to enter into this Agreement and to authorize, issue and sell the Shares as contemplated by this Agreement.

(d) The Company has been duly organized and is validly existing as a corporation in good standing under the laws of the State of Delaware, with corporate power and authority to own or lease its properties and conduct its business as described in the Registration Statement. Each of the subsidiaries of the Company, as listed in Schedule II hereto (collectively, the “Subsidiaries”), has been duly organized and is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, with corporate power and authority to own or lease its properties and conduct its business as described in the Registration Statement. The Subsidiaries are the only subsidiaries, direct or indirect, of the Company. The Company and each of the Subsidiaries are duly qualified to transact business and are in good standing in all jurisdictions in which the conduct of their business requires such qualification; except where the failure to be so qualified or to be in good standing would not have a material adverse effect on the condition (financial or otherwise), properties, assets, liabilities, rights, operations, earnings, business, management or prospects of the Company and its Subsidiaries taken as a whole, whether or not arising from transactions in the ordinary course of business (a “Material Adverse Effect”). The outstanding shares of capital stock of each of the Subsidiaries have been duly authorized and validly issued, are fully paid and non-assessable and are wholly owned by the Company or another Subsidiary free and clear of all liens, encumbrances and equities and claims; and no options, warrants or other rights to purchase, agreements or other obligations to issue or other rights to convert any obligations into shares of capital stock or ownership interests in the Subsidiaries are outstanding.

(e) The outstanding shares of Common Stock of the Company have been duly authorized and validly issued and are fully paid and non-assessable; the Shares to be issued and sold by the Company have been duly authorized and when issued and paid for as contemplated herein will be validly issued, fully paid and non-assessable; and no preemptive rights of Stockholders exist with respect to any of the Shares or the issue and sale thereof. Neither the filing of the Registration Statement nor the offering or sale of the Shares as contemplated by this Agreement gives rise to any rights, other than those that have been waived or satisfied, for or relating to the registration of any shares of Common Stock.

(f) All of the Shares conform to the description thereof incorporated by reference in the Registration Statement. The form of certificates for the Shares conforms to the corporate law of the jurisdiction of the Company’s incorporation. Immediately after the issuance and sale of the Shares to the Underwriters, no shares of Preferred Stock of the Company shall be issued and outstanding and no holder of any shares of capital stock, securities convertible into or exchangeable or exercisable for capital stock or options, warrants or other rights to purchase capital stock or any other securities of the Company shall have any existing or future right to acquire any shares of Preferred Stock of the Company. No holders of securities of the Company have rights to the registration of such securities under the Registration Statement that have not been waived.

(g) The Company has not distributed and will not distribute any prospectus or other offering material (including, without limitation, content on the Company’s website that may be deemed to be a prospectus or other offering material) in connection with the offering and sale of the Shares other than any Preliminary Prospectus or the Prospectus or other materials permitted by the Act to be distributed by the Company.

(h) The consolidated financial statements of the Company and the Subsidiaries, together with related notes and schedule, as set forth or incorporated by reference in the Registration Statement, present fairly the financial position and the results of operations and cash flows of the Company and the consolidated Subsidiaries, at the indicated dates and for the indicated periods. Such financial statements and related schedule have been prepared in accordance with U.S. generally accepted principles of accounting, consistently applied throughout the periods involved, except as disclosed therein, and all adjustments necessary for a fair presentation of results for such periods have been made. The summary financial and statistical data included or incorporated by reference in the Registration Statement present fairly the information shown therein, and such data have been compiled on a basis consistent with the financial statements presented therein and the books and records of the Company. The pro forma financial statements and other pro forma financial information included or incorporated by reference in the Registration Statement and the Prospectus present fairly the information shown therein, have been prepared in accordance with the Commission’s rules and guidelines with respect to pro forma financial statements and have been properly compiled on the pro forma bases described therein, and, in the opinion of the Company, the assumptions used in the preparation thereof are reasonable and the adjustments used therein are appropriate to give effect to the transactions or circumstances referred to therein.

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

(j) PricewaterhouseCoopers LLP, which has certified certain financial statements of the Company and delivered its opinion with respect to the audited financial statements and schedule included in the Registration Statement and the Prospectus, are independent public accountants with respect to the Company within the meaning of the Act and the Rules and Regulations.

(k) There is no action, suit, claim or proceeding pending or, to the Company’s knowledge, threatened against the Company or any of the Subsidiaries before any court or administrative agency or otherwise that if determined adversely to the Company or any of its Subsidiaries might have a Material Adverse Effect or prevent the consummation of the transactions contemplated hereby, except as set forth in the Registration Statement and the Prospectus.

(l) No labor problem or dispute with the employees of the Company or any of the Subsidiaries exists or, to the Company’s knowledge, is threatened or imminent, and the Company is not aware of any existing or imminent labor disturbance by the employees of any of its

or its Subsidiaries’ principal suppliers, contractors or customers, that could have a Material Adverse Effect.

(m) The Company and the Subsidiaries have good and marketable title to all of the properties and assets reflected in the financial statements (or as described in the Registration Statement) hereinabove described, subject to no lien, mortgage, pledge, charge or encumbrance of any kind except those reflected in such financial statements (or as described in the Registration Statement) or that are not material in amount. The Company and the Subsidiaries occupy their leased properties under valid and binding leases conforming in all material respects to the description thereof set forth or incorporated by reference in the Registration Statement and the Prospectus.

(n) The Company and the Subsidiaries have filed all Federal, State, local and foreign tax returns that have been required to be filed and have paid all taxes indicated by said returns and all assessments received by them or any of them to the extent that such taxes have become due and are not being contested in good faith and for which an adequate reserve for accrual has been established in accordance with U.S. generally accepted accounting principles. All tax liabilities have been adequately provided for in the financial statements of the Company, and the Company does not know of any actual or proposed additional material tax assessments. There are no transfer taxes or other similar fees or charges under Federal law or the laws of any state, or any political subdivision thereof, required to be paid in connection with the execution and delivery of this Agreement or the issuance or sale by the Company of the Shares.

(o) Since the respective dates as of which information is given in the Registration Statement and the Prospectus, as it may be amended or supplemented, there has not been any material adverse change or any development involving a prospective change that has had or is reasonably likely to have a Material Adverse Effect, whether or not occurring in the ordinary course of business, and there has not been any material transaction entered into or any material transaction that is probable of being entered into by the Company or the Subsidiaries, other than transactions in the ordinary course of business and changes and transactions described in the Registration Statement and the Prospectus, as it may be amended or supplemented. The Company and the Subsidiaries have no material contingent obligations that are not disclosed in the Company’s financial statements in the Registration Statement and the Prospectus.

(p) Neither the Company nor any of the Subsidiaries is, or with the giving of notice or lapse of time or both will be, in violation of or in default under its Certificate of Incorporation (“Charter”) or By-Laws or under any agreement, lease, contract, indenture or other instrument or obligation to which it is a party or by which it, or any of its properties, is bound and which default has had or is reasonably likely to have a Material Adverse Effect. The execution and delivery of this Agreement and the consummation of the transactions herein contemplated and the fulfillment of the terms hereof will not conflict with or result in a breach of any of the terms or provisions of, or constitute a default under, any contract, indenture, mortgage, deed of trust or other agreement or instrument to which the Company or any of the Subsidiaries is a party, or of the Charter or By-Laws of the Company or of any order, rule or regulation applicable to the Company or any of the Subsidiaries of any court or of any regulatory body, administrative agency or other governmental body having jurisdiction.

(q) Each approval, consent, order, authorization, designation, declaration or filing by or with any regulatory, administrative or other governmental body necessary in connection with the execution and delivery by the Company of this Agreement and the consummation of the transactions herein contemplated (except such additional steps as may be required by the Commission or the National Association of Securities Dealers, Inc. (the “NASD”) or such additional steps as may be necessary to qualify the Shares for public offering by the Underwriters under state securities or Blue Sky laws) has been obtained or made and is in full force and effect.

(r) The Company and each of the Subsidiaries have all material licenses, certifications, permits, franchises, approvals, clearances and other regulatory authorizations (“Permits”) from governmental authorities as are necessary to conduct their respective businesses as currently conducted and to own, lease and operate their respective properties in the manner described in the Prospectus. There is no claim, proceeding or controversy, pending or, to the knowledge of the Company or any of the Subsidiaries, threatened, involving the status of or sanctions under any of the Permits. The Company and each of the Subsidiaries have fulfilled and performed all of their respective material obligations with respect to the Permits, and no event has occurred that allows, or after notice or lapse of time would allow, the revocation, termination, modification or other impairment of the rights of the Company or any of the Subsidiaries under any Permit. None of the Permits contains any restriction that is materially burdensome on the Company or any of its Subsidiaries.

(s) To the Company’s knowledge, there are no affiliations or associations between any member of the NASD and any of the Company’s officers, directors or 5% or greater security holders, except as set forth in the Registration Statement.

(t) Neither the Company nor, to the Company’s knowledge, any of its affiliates has taken or may take, directly or indirectly, any action designed to cause or result in, or that has constituted or that might reasonably be expected to constitute, the stabilization or manipulation of the price of the shares of the Company’s Common Stock to facilitate the sale or resale of the Shares. The Company acknowledges that the Underwriters may engage in passive market making transactions in the Shares on The Nasdaq Stock Market in accordance with Regulation M under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

All policies of insurance insuring the Company or any Subsidiary or any of their respective businesses, assets, employees, officers and directors are in full force and effect, and the Company and the Subsidiaries are in compliance with the terms of such policies in all material respects. There are no claims by the Company or any Subsidiary under any such policy or instrument as to which an insurance company is denying liability or defending under a reservation of rights clause.

(w) The Company is in compliance in all material respects with all presently applicable provisions of the Employee Retirement Income Security Act of 1974, as amended, including the regulations and published interpretations thereunder (“ERISA”); no “reportable event” (as defined in ERISA) has occurred with respect to any “pension plan” (as defined in ERISA) for which the Company would have any liability; the Company has not incurred and does not expect to incur liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “pension plan” or (ii) Section 412 or 4971 of the Internal Revenue Code of 1986, as amended, including the regulations and published interpretations thereunder (the “Code”); and each “pension plan” for which the Company would have any liability that is intended to be qualified under Section 401(a) of the Code is so qualified in all material respects and nothing has occurred, whether by action or by failure to act, that would cause the loss of such qualification.

Neither the Company nor any Subsidiary, nor, to the Company’s knowledge, any director, officer, agent, employee or other person associated with

None of the technology employed by the Company has been obtained or, to the Company’s knowledge, is being used by the Company in violation of the rights of any person or third party. The Company knows of no infringement or misappropriation by others of Intellectual Property. Schedule III lists all of the issued patents in which the Company or any of the Subsidiaries has rights.

(dd) The conduct of business by the Company and each of the Subsidiaries complies, and at all times has complied, in all material respects with federal, state, local and foreign laws, statutes, ordinances, rules, regulations, decrees, orders, Permits and other similar items

(“Laws”) applicable to its business, including, without limitation, (a) the Occupational Safety and Health Act, the Environmental Protection Act and the Toxic Substance Control Act and (b) licensing and certification Laws covering any aspect of the business of the Company or any of the Subsidiaries. Neither the Company nor any of the Subsidiaries has received any notification asserting, or has knowledge of, any present or past failure to comply with or violation of any such Laws.

(ee) The information contained in the Registration Statement and the Prospectus regarding the Company’s expectations, plans and intentions, and any other information that constitutes “forward-looking” information within the meaning of the Act and the Exchange Act were made by the Company on a reasonable basis and reflect the Company’s good faith belief and/or estimate of the matters described therein.

(ff) Any certificate signed by any officer of the Company and delivered to the Representatives or counsel for the Underwriters in connection with the offering of the Shares contemplated hereby shall be deemed a representation and warranty by the Company to each Underwriter and shall be deemed to be a part of this Section 1 and incorporated herein by this reference.

2. Purchase, Sale and Delivery of the Firm Shares.

(a) On the basis of the representations, warranties and covenants herein contained, and subject to the conditions herein set forth, the Company agrees to sell to the Underwriters and each Underwriter agrees, severally and not jointly, to purchase, at a price of $ per share, the number of Firm Shares set forth opposite its name in Schedule I hereof, subject to adjustments in accordance with Section 9 hereof.

(b) Payment for the Firm Shares to be sold hereunder is to be made in Federal (same day) funds to an account designated by the Company against delivery of certificates therefor to the Representatives for the several accounts of the Underwriters. Such payment and delivery are to be made through the facilities of the Depository Trust Company, New York, New York at 10:00 a.m., New York time, on the third business day after the date of this Agreement or at such other time and date not later than five business days thereafter as you and the Company shall agree upon, such time and date being herein referred to as the “Closing Date.” As used herein, “business day” means a day on which the New York Stock Exchange is open for trading and on which banks in New York are open for business and are not permitted by law or executive order to be closed. [For non-FASS issues only: The certificates for the Firm Shares will be delivered in such denominations and in such registrations as the Representatives request in writing not later than the second full business day prior to the Closing Date, and will be made available for inspection by the Representatives at least one business day prior to the Closing Date.]

(c) 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 several Underwriters to purchase the Option Shares at the price per share set forth in the first paragraph of this Section. The option granted hereby may be exercised, in whole or in part by giving written notice (i) at any time before the Closing Date and (ii) only once thereafter within 30 days after the date of this Agreement, by you, as the Representatives of the several Underwriters, to the Company setting

forth the number of Option Shares as to which the several Underwriters are exercising the option, the names and denominations in which the Option Shares are to be registered and the time and date at which such certificates are to be delivered. The time and date at which certificates for Option Shares are to be delivered shall be determined by the Representatives but shall not be earlier than three nor later than 10 full business days after the exercise of such option, nor in any event prior to the Closing Date (such time and date being herein referred to as the “Option Closing Date”). If the date of exercise of the option is three or more days before the Closing Date, the notice of exercise shall set the Closing Date as the Option Closing Date. The number of Option Shares to be purchased by each Underwriter shall be in the same proportion to the total number of Option Shares being purchased as the number of Firm Shares being purchased by such Underwriter bears to the total number of Firm Shares, adjusted by you in such manner as to avoid fractional shares. The option with respect to the Option Shares granted hereunder may be exercised only to cover over-allotments in the sale of the Firm Shares by the Underwriters. You, as the Representatives of the several Underwriters, may cancel such option at any time prior to its expiration by giving written notice of such cancellation to the Company. To the extent, if any, that the option is exercised, payment for the Option Shares shall be made on the Option Closing Date in Federal (same day) funds drawn to the order of the Company against delivery of certificates therefor through the facilities of the Depository Trust Company in New York, New York drawn to the order of the Company.

3. Offering by the Underwriters.

It is understood that the several Underwriters are to make a public offering of the Firm Shares as soon as the Representatives deem it advisable to do so. The Firm Shares are to be initially offered to the public at the public offering price set forth in the Prospectus. The Representatives may from time to time thereafter change the public offering price and other selling terms. To the extent, if at all, that any Option Shares are purchased pursuant to Section 2 hereof, the Underwriters will offer them to the public on the foregoing terms.

It is further understood that you will act as the Representatives for the Underwriters in the offering and sale of the Shares in accordance with a Master Agreement Among Underwriters entered into by you and the other several Underwriters.

4. Covenants of the Company.

The Company covenants and agrees with the several Underwriters that:

(a) The Company will (i) use its best efforts to cause the Registration Statement to become effective or, if the procedure in Rule 430A of the Rules and Regulations is followed, to prepare and timely file with the Commission under Rule 424(b) of the Rules and Regulations a Prospectus in a form approved by the Representatives containing information previously omitted at the time of effectiveness of the Registration Statement in reliance on Rule 430A of the Rules and Regulations; (ii) not file any amendment to the Registration Statement or supplement to the Prospectus of which the Representatives shall not previously have been advised and furnished with a copy or to which the Representatives shall have reasonably objected in writing or which is not in compliance with the Rules and Regulations; and (iii) file on a timely basis all reports and any definitive proxy or information statements required to be filed by the Company with the Commission subsequent to the date of the Prospectus and prior to the termination of the offering of the Shares by the Underwriters.

(b) The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of any securities of the Company.

(c) The Company will advise the Representatives promptly (i) when the Registration Statement or any post-effective amendment thereto shall have become effective; (ii) of receipt of any comments from the Commission; (iii) of any request of the Commission for amendment of the Registration Statement or for supplement to the Prospectus or for any additional information; and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the use of the Prospectus or of the institution of any proceedings for that purpose. The Company will use its best efforts to prevent the issuance of any such stop order preventing or suspending the use of the Prospectus and to obtain as soon as possible the lifting thereof, if issued.

(d) The Company will cooperate with the Representatives in endeavoring to qualify the Shares for sale under the securities laws of such jurisdictions as the Representatives may reasonably have designated in writing and will make such applications, file such documents and furnish such information as may be reasonably required for that purpose, provided the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent. The Company will, from time to time, prepare and file such statements, reports and other documents, as are or may be required to continue such qualifications in effect for so long a period as the Representatives may reasonably request for distribution of the Shares.

(e) The Company will deliver to, or upon the order of, the Representatives, from time to time, as many copies of any Preliminary Prospectus as the Representatives may reasonably request. The Company will deliver to, or upon the order of, the Representatives during the period when delivery of a Prospectus is required under the Act, as many copies of the Prospectus in final form, or as thereafter amended or supplemented, as the Representatives may reasonably request. The Company will deliver to the Representatives at or before the Closing Date, four signed copies of the Registration Statement and all amendments thereto including all exhibits filed therewith, and will deliver to the Representatives such number of copies of the Registration Statement (including such number of copies of the exhibits filed therewith as may reasonably be requested) and of all amendments thereto, as the Representatives may reasonably request.

(f) The Company will comply with the Act and the Rules and Regulations, the Exchange Act, and the rules and regulations of the Commission thereunder, so as to permit the completion of the distribution of the Shares as contemplated in this Agreement and the Prospectus. If, during the period in which a prospectus is required by law to be delivered by an Underwriter or dealer, any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Underwriters, it becomes necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances existing at the time the Prospectus is delivered to a purchaser, not misleading, or, if it is necessary at any time to amend or supplement the Prospectus to comply with any law, the Company promptly will prepare and file with the Commission an appropriate amendment to the Registration Statement or supplement to the

(vi) The statements under the captions “Employment, Severance and Change in Control Agreements” and “Certain Transactions” in the Company’s definitive proxy statement filed on April , 2004 and in the Forms 8-A incorporated by reference in the Prospectus, insofar as such statements constitute a summary of documents referred to therein or matters of law, fairly summarize in all material respects the information called for with respect to such documents and matters.

(xii) The Company is not, and will not become, as a result of the consummation of the transactions contemplated by this Agreement and application of the net proceeds therefrom as described in the Prospectus, required to register as an investment company under the 1940 Act.

In addition to the matters set forth above, such opinion shall also include a statement to the effect that nothing has come to the attention of such counsel which leads them to believe that (i) the Registration Statement, at the time it became effective under the Act (but after giving effect to any modifications incorporated therein pursuant to Rule 430A under the Act) and as of the Closing Date or the Option Closing Date, if any, 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, and (ii) the Prospectus, or any supplement thereto, on the date it was filed pursuant to the Rules and Regulations and as of the Closing Date or the Option Closing Date, if any, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements, in the light of the circumstances under which they are made, not misleading (except that such counsel need express no view as to financial statements and related schedules therein). With respect to such statement, ▇▇▇▇▇▇ Godward LLP may state that their belief is based upon the procedures set forth therein, but is without independent check and verification.

(c) The Representatives shall have received from Fenwick & West LLP, counsel for the Underwriters, an opinion dated the Closing Date and the Option Closing Date, if any, with respect to the formation of the Company, the validity of the Shares and such other related matters as the Representatives reasonably may request, and such counsel shall have received such papers and information as they request to enable them to pass upon such matters.

(e) The Representatives shall have received, on each of the dates hereof, the Closing Date and the Option Closing Date, if any, a letter dated the date hereof, the Closing Date or the Option Closing Date, if any, in form and substance satisfactory to you, of PricewaterhouseCoopers LLP confirming that they are independent public accountants within the meaning of the Act and the applicable published Rules and Regulations thereunder and stating that in their opinion the financial statements and schedules examined by them and included in the Registration Statement comply as to form in all material respects with the applicable accounting requirements of the Act and the related published Rules and Regulations; and containing such other statements and information as is ordinarily included in accountants’ “comfort letters” to Underwriters with respect to the financial

statements and certain financial and statistical information contained or incorporated by reference in the Registration Statement and the Prospectus.

(f) The Representatives shall have received on the Closing Date and the Option Closing Date, if any, a certificate or certificates of the Company’s Chief Executive Officer and Chief Financial Officer to the effect that, as of the Closing Date or the Option Closing Date, if any, each of them severally represents as follows:

(i) The Registration Statement has become effective under the Act and no stop order suspending the effectiveness of the Registrations Statement has been issued, and no proceedings for such purpose have been taken or are, to his knowledge, contemplated by the Commission;

(ii) The representations and warranties of the Company contained in Section 1 hereof are true and correct as of the Closing Date or the Option Closing Date, if any;

(iii) All filings required to have been made pursuant to Rule 424 or 430A under the Act have been made;

(iv) They have carefully examined the Registration Statement and the Prospectus and, in their opinion, as of the effective date of the Registration Statement, the statements contained in the Registration Statement were true and correct, and such Registration Statement and Prospectus and the documents incorporated therein by reference did not omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading, and since the effective date of the Registration Statement, no event has occurred that should have been set forth in a supplement to or an amendment of the Prospectus which has not been so set forth in such supplement or amendment; and

(v) Since the respective dates as of which information is given in the Registration Statement and the Prospectus, there has not been any material adverse change or any development involving a prospective change that has had or is reasonably likely to have a Material Adverse Effect, whether or not arising in the ordinary course of business.

(g) The Company shall have furnished to the Representatives such further certificates and documents confirming the representations and warranties, covenants and conditions contained herein and related matters as the Representatives may reasonably have requested.

(h) The Firm Shares and Option Shares, if any, have been approved for designation upon notice of issuance on The Nasdaq Stock Market.

(i) The Lockup Agreements described in Section 4(k) are in full force and effect.

(j) The Representatives shall have received on the Closing Date and the Option Closing Date, if any, opinions of LLP, special counsel for the Company with respect to patent and proprietary rights, dated the Closing Date and the Option Closing Date, if any, addressed to the Underwriters (and stating that it may be relied upon by Fenwick & West LLP, counsel for the Underwriters) to the effect that:

(i) To such counsel’s knowledge, except as described in the Prospectus, (A) the Company and its Subsidiaries have valid license rights or clear title to the Intellectual Property referenced in the Prospectus, and there are no rights of third parties to any such Intellectual Property; (B) there is no infringement, misappropriation or other violation by third parties of any of the Intellectual Property of the Company and its Subsidiaries referenced in the Prospectus; (C) there is no infringement, misappropriation or other violation by the Company and its Subsidiaries of any Intellectual Property of others; (D) there is no pending or threatened action, suit, proceeding or claim by governmental authorities or others that the Company and its Subsidiaries infringe or otherwise violate any Intellectual Property of others, and such counsel is unaware of any facts that would form a reasonable basis for any such claim; and (E) there is no pending or threatened action, suit, proceeding or claim by governmental authorities or others challenging the rights of the Company and its Subsidiaries in or to, or challenging the scope of, any Intellectual Property of the Company and its Subsidiaries referenced in the Prospectus, and such counsel is unaware of any facts that would form a reasonable basis for any such claim.

(ii) To such counsel’s knowledge, the patent applications of the Company and its Subsidiaries presently on file disclose patentable subject matter, and such counsel is not aware of any inventorship challenges, any interference that has been declared or provoked, or any other material fact with respect to the patent applications of the Company and its Subsidiaries presently on file that (A) would preclude the issuance of patents with respect to such applications or (B) would lead such counsel to conclude that such patents, when issued, would not be valid and enforceable in accordance with applicable regulations.

(iii) Such counsel has reviewed the “Risk Factors” and “Business” portions of the Registration Statement and the Prospectus referencing certain Company patent rights, (collectively, the “Patent Sections”). On the basis of such counsel’s representation of the Company, such counsel has no reason to believe that the information in the Patent Sections contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements therein not misleading and insofar as such Patent Sections constitute statements or summaries of matters of law, to such counsel’s knowledge, are, in all material respects, accurate and complete statements or summaries, as the case may be, of the matters referred to therein.

The opinions and certificates mentioned in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in all material respects satisfactory to the Representatives and to Fenwick & West LLP, counsel for the Underwriters.

If any of the conditions hereinabove provided for in this Section shall not have been fulfilled when and as required by this Agreement to be fulfilled, the obligations of the Underwriters hereunder may be terminated by the Representatives by notifying the Company of such termination in writing on or prior to the Closing Date or the Option Closing Date, if any.

In such event, the Company and the Underwriters shall not be under any obligation to each other (except to the extent provided in Sections 5 and 8 hereof).

7. Conditions of the Obligations of the Company.

The obligations of the Company to sell and deliver the portion of the Shares required to be delivered as and when specified in this Agreement are subject to the conditions that, at the Closing Date or the Option Closing Date, if any, no stop order suspending the effectiveness of the Registration Statement shall have been issued and in effect or proceedings therefor initiated or threatened.

8. Indemnification.

(a) The Company agrees:

(i) to indemnify and hold harmless each Underwriter, and each person, if any, who controls any Underwriter within the meaning of the Act, against any losses, claims, damages or liabilities to which such Underwriter or any such controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any act or failure to act or any alleged act or failure to act by any Underwriter in connection with, or relating in any manner to, the Shares or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clause (i) or (ii) above (provided, however, that the Company shall not be liable under this clause (iii) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Underwriter through its gross negligence or willful misconduct); provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Prospectus, or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by or through the Representatives specifically for use in the preparation thereof.

(ii) to reimburse each Underwriter and each such controlling person upon demand for any legal or other out-of-pocket expenses reasonably incurred by such Underwriter or such controlling person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding or in responding to a subpoena or governmental inquiry related to the offering of the Shares, whether or not such Underwriter or controlling person is a party to any action or proceeding. In the event that it is finally judicially determined that the Underwriters were not entitled to receive payments for legal and other expenses pursuant to this subparagraph, the Underwriters will promptly return all sums that had been advanced pursuant hereto.

(b) Each Underwriter severally and not jointly will indemnify and hold harmless the Company, each of its directors, each of its officers who have signed the Registration Statement and each person, if any, who controls the Company within the meaning of the Act, against any losses, claims, damages or liabilities to which the Company or any such director, officer or controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities

(or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, or (ii) the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; and will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer or controlling person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however, that each Underwriter will be liable in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any Preliminary Prospectus, the Prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by or through the Representatives specifically for use in the preparation thereof.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing. No indemnification provided for in Section 8(a) or (b) shall be available to any party who shall fail to give notice as provided in this Subsection if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability that it or they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 8(a) or (b). In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party and shall pay as incurred the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the fees and expenses of the counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party shall have failed to assume the defense and employ counsel acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action.

It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm for all such indemnified parties. Such firm shall be designated in writing by you in the case of parties indemnified pursuant to Section 8(a) and by the Company in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but, if a matter settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. In addition, the indemnifying party will not, without the prior written consent of the

indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding for which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding.

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

The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Subsection were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to above in this Subsection. The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Subsection shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Subsection, (i) no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares purchased by such Underwriter and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this Subsection to contribute are several in proportion to their respective underwriting obligations and not joint.

(f) In any proceeding relating to the Registration Statement, any Preliminary Prospectus, the Prospectus or any supplement or amendment thereto, each party against whom contribution may be sought under this Section hereby consents to the jurisdiction of any court having jurisdiction over any other contributing party, agrees that process issuing from such court may be

served upon him or it by any other contributing party and consents to the service of such process and agrees that any other contributing party may join him or it as an additional defendant in any such proceeding in which such other contributing party is a party.

(g) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section and the representations and warranties of the Company set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter, the Company, its directors or officers or any persons controlling the Company, (ii) acceptance of any Shares and payment therefor hereunder, and (iii) any termination of this Agreement. A successor to any Underwriter, or to the Company, its directors or officers, or any person controlling the Company, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section.

9. Default by Underwriters.

If on the Closing Date or the Option Closing Date, if any, any Underwriter shall fail to purchase and pay for the portion of the Shares that such Underwriter has agreed to purchase and pay for on such date (otherwise than by reason of any default on the part of the Company), you, as the Representatives of the Underwriters, shall use your reasonable efforts to procure within 36 hours thereafter one or more of the other Underwriters, or any others, to purchase from the Company, in such amounts as may be agreed upon and upon the terms set forth herein, the Firm Shares or Option Shares, as the case may be, that the defaulting Underwriter or Underwriters failed to purchase. If during such 36 hours you, as such Representatives, shall not have procured such other Underwriters, or any others, to purchase the Firm Shares or Option Shares, as the case may be, agreed to be purchased by the defaulting Underwriter or Underwriters, then (a) if the aggregate number of shares with respect to which such default shall occur does not exceed 10% of the Firm Shares or Option Shares, as the case may be, covered hereby, the other Underwriters shall be obligated, severally, in proportion to the respective numbers of Firm Shares or Option Shares, as the case may be, that they are obligated to purchase hereunder, to purchase the Firm Shares or Option Shares, as the case may be, that such defaulting Underwriter or Underwriters failed to purchase or (b) if the aggregate number of Firm Shares or Option Shares, as the case may be, with respect to which such default shall occur exceeds 10% of the Firm Shares or Option Shares, as the case may be, covered hereby, the Company or you as the Representatives of the Underwriters will have the right, by written notice given within the next 36-hour period to the parties to this Agreement, to terminate this Agreement without liability on the part of the non-defaulting Underwriters or of the Company except to the extent provided in Section 8 hereof. In the event of a default by any Underwriter or Underwriters, as set forth in this Section, the Closing Date or Option Closing Date, if any, may be postponed for such period, not exceeding seven days, as you, as Representatives, may determine in order that the required changes in the Registration Statement or in the Prospectus or in any other documents or arrangements may be effected. The term “Underwriter” includes any person substituted for a defaulting Underwriter. Any action taken under this Section shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.
