(e) All licenses or other agreements under which the Company has granted rights to Intellectual Property to others (including all end-user agreements) are (i) in full force and effect, (ii) not subject to material default by the Company, and (iii) to the Company’s Knowledge, not subject to material default by any other party thereto.

To the Knowledge of the Company, the Company is not using unlawfully any Intellectual Property of any other Person, including, without limitation, any former employer of any past or present employees of the Company. To the Knowledge of the Company, neither the Company, nor any of its employees has any agreements or arrangements with former employers of such employees relating to any Intellectual Property of such employers, which materially interfere or conflict with the performance of such employee’s duties for the Company or result in any former employers of such employees having any rights in, or claims on, the Company’s Intellectual Property. Each current employee of the Company has executed agreements regarding confidentiality, proprietary information and assignment of inventions and copyrights to the Company, each independent contractor or consultant of the Company has executed agreements regarding confidentiality and proprietary information, and the Company has not received written notice that any employee, consultant or independent contractor is in violation of any agreement or in breach of any agreement or arrangement with former or present employers relating to proprietary information or assignment of inventions.

Other than with respect to the registration rights granted to various investors pursuant to that certain Registration Rights Agreement dated September 28, 2005, the Company has not granted or agreed to grant to any Person any rights (including “piggy-back” registration rights) to have any securities of the Company registered with the Commission or any other Governmental Authority, which registration obligation has not been satisfied in full or waived prior to the date hereof.

3.12 Solicitation; Other Issuances of Securities. Neither the Company nor any of its Affiliates, nor any Person acting on its or their behalf, (i) has engaged in any form of general solicitation or general

advertising (within the meaning of Regulation D) in connection with the offer or sale of the Securities, or (ii) has, directly or indirectly, made any offers or sales of any security or the right to purchase any security, or solicited any offers to buy any security or any such right, under circumstances that would require registration of the Securities under the Securities Act.

3.13 Fees. Except as otherwise disclosed to the Investors, the Company is not obligated to pay any brokers, finders or financial advisory fees or commissions to any underwriter, broker, agent or other representative in connection with the transactions contemplated hereby. The Company will indemnify and hold harmless such Investor from and against any claim by any Person alleging that such Investor is obligated to pay any such compensation, fee, cost or related expenditure in connection with the transactions contemplated hereby.

3.14 Foreign Corrupt Practices. Neither the Company, nor, to the Knowledge of the Company, any director, officer, agent, employee or other Person acting on behalf of the Company, has (i) used any corporate funds for any unlawful contribution, gift or entertainment expense relating to political activity, (ii) made any direct or indirect unlawful payment to any foreign or domestic government official or employee, or (iii) violated any provision of the Foreign Corrupt Practices Act of 1977, as amended, or made any bribe, rebate, payoff, influence payment, kickback or other unlawful payment to any foreign or domestic government official or employee.

The Company has complied in all material respects with all applicable federal and state equal opportunity and other laws related to employment.

3.16 Environment. Except as disclosed in the Disclosure Documents, the Company has no liabilities under any Environmental Law, nor, to the Company’s Knowledge, do any factors exist that are reasonably likely to give rise to any such liability, affecting any of the properties owned or leased by the Company that, individually or in the aggregate, has had or would reasonably be expected to have a Material Adverse Effect. The Company has not violated any Environmental Law applicable to it now or previously in effect, other than such violations or infringements that, individually or in the aggregate, have not had and would not reasonably be expected to have a Material Adverse Effect.

3.17 ERISA. The Company is in compliance with the presently applicable provisions of ERISA and the United States Internal Revenue Code of 1986, as amended, with respect to each Pension Plan except in any such case for any such matters that, individually or in the aggregate, have not had, and would not reasonably be expected to have, a Material Adverse Effect.

3.18 Disclosure. The representations, warranties and written statements contained in this Agreement and the other Transaction Documents and in the certificates, exhibits and schedules delivered to such Investor by the Company pursuant to this Agreement and the other Transaction Documents and in connection with such Investor’s due diligence investigation of the Company, do not contain any untrue statement of a material fact, and do not omit to state a material fact required to be stated therein or necessary in order to make such representations, warranties or statements not misleading in light of the circumstances under which they were made. The Company acknowledges that such Investor is relying on the representations, acknowledgments and agreements made by the Company in this Section 3.18 and elsewhere in this Agreement in making trading and other decisions concerning the Company’s securities.

3.19 Insurance. The Company maintains insurance in such amounts and covering such losses and risks as is reasonably sufficient and customary in the businesses in which the Company is engaged. As of the date hereof and as of the Closing Date, no notice of cancellation has been received for any of

such policies and the Company is in compliance in all material respects with all of the terms and conditions thereof. The Company has no reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue to conduct its business as currently conducted without a significant increase in cost. Without limiting the generality of the foregoing, the Company maintains director’s and officer’s insurance in an amount not less than $10 million for each covered occurrence.

Any Property held under lease by the Company is held by it under valid, subsisting and enforceable leases with such exceptions as are not material and do not interfere with the use made or proposed to be made of such Property by the Company.

3.21 Regulatory Permits. The Company possesses all certificates, authorizations and permits issued by the appropriate federal, state or foreign regulatory Governmental Authorities necessary to conduct its businesses, except where the failure to have any such authorization or permit would have a Material Adverse Effect, and the Company has not received any notice of proceedings relating to the revocation or modification of any such certificate, authorization or permit.

3.22 Exchange Act Registration. The Company’s Common Stock is registered pursuant to Section 12(g) of the Exchange Act and is listed on the Nasdaq Global Market.

The Company meets the continued listing requirements of the Nasdaq Global Market.

3.23 Investment Company Status. The Company is not, and immediately after receipt of payment for the Shares and the Warrants issued under this Agreement will not be, an “investment company” or an entity “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940, as amended (the “Investment Company Act”), and shall conduct its business in a manner so that it will not become subject to the Investment Company Act.

3.24 Transfer Taxes.

The Company’s accountants that rendered their opinion with respect to the financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2005, are, to the Knowledge of the Company, independent accountants as required by the Securities Act.

3.28 Compliance with Laws. The Company has conducted the business in compliance in all material respects with all applicable laws, except where non-compliance has not had or would not reasonably be expected to have a Material Adverse Effect.

3.29 No Integration. Assuming the accuracy of the Investors’ representations and warranties set forth in Section 2 of this Agreement, neither the Company, nor to the Knowledge of the Company, any of its Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities to be integrated with prior offerings by the Company for purposes of the Securities Act or any applicable shareholder approval provisions, including, without limitation, under the rules and regulations of the Nasdaq Global Market.

4. COVENANTS OF THE COMPANY AND EACH INVESTOR.

4.1 The Company agrees with each Investor that the Company will:

(a) file a Form D with respect to the Securities issued at the Closing as and when required under Regulation D and provide a copy thereof to such Investor promptly after such filing; and

(b) take such action as the Company reasonably determines upon the advice of counsel is necessary to qualify the sale of the Shares and Warrants to the Investors under applicable state or “blue-sky” laws or obtain an exemption therefrom, and shall promptly provide evidence of any such action to such Investor at such Investor’s request.

4.2 Existence and Compliance. The Company agrees that it will, while any Investor holds any Shares or Warrants:

(a) maintain its corporate existence in good standing;

(b) comply with all Governmental Requirements applicable to the operation of its business, except for instances of noncompliance that would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect;

(c) comply with all Material Contracts, except for instances of noncompliance that would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect;

(d) provide each Investor with copies of all materials sent to its shareholders at the same time as such materials are delivered to such shareholders;

(e) timely file with the Commission all reports required to be filed pursuant to the Exchange Act and refrain from terminating its status as an issuer required by the Exchange Act to file reports thereunder even if the Exchange Act or the rules or regulations thereunder would permit such termination;

(f) until the Effective Date, take commercially reasonable steps to restrict each of the Company’s executive officers (as defined in Rule 501(f) of the Securities Act) (each, a “Key Employee”) from selling shares of Common Stock, other than in connection with any 10b-5(1) trading plans in effect as of the Execution Date and disclosed to each Investor in writing; and

(g) use commercially reasonable efforts to maintain adequate insurance coverage (including D&O insurance) for the Company.

4.3 Reservation of Common Stock. The Company shall, on the Closing Date, have authorized and reserved for issuance to the Investors free from any preemptive rights, and shall keep available at all times during which any Warrants are outstanding, a number of shares of Common Stock (the “Reserved Amount”) that, on the Closing Date, is equal to the number of Warrant Shares issuable upon exercise of all of the Warrants issued at the Closing without regard to any limitation or restriction on exercise that may be set forth in the Warrants. The Reserved Amount shall be allocated in accordance with each Investor’s Pro Rata Share. In the event that an Investor shall sell or otherwise transfer any of such Investor’s Warrants, each transferee shall be allocated a pro rata portion of such transferor’s Reserved Amount. While any Warrants are outstanding, the Company shall not reduce the Reserved Amount without obtaining the prior written consent of each Investor then holding Warrants.

4.4 Use of Proceeds. The Company shall use the proceeds from the sale of the Shares and Warrants for working capital and general corporate purposes; provided that the Company shall not use any of such proceeds (i) to pay any dividend or make any distribution on any of its securities, or (ii) to repay any loan made to or incurred by any Key Employee or any other officer or director or Affiliate of the Company.

4.5 Transactions with Affiliates. The Company agrees that any transaction or arrangement between it and any Affiliate or employee of the Company shall be effected on an arms’ length basis and shall be approved by the Company’s independent directors.

4.6 Use of Investor Name. Except as may be required by applicable law and/or this Agreement, the Company shall not use, directly or indirectly, any Investor’s name or the name of any of its Affiliates in any advertisement, announcement, press release or other similar communication unless it has received the prior written consent of any Investor for the specific use contemplated or as otherwise required by applicable law or regulation.

4.7 Company’s Instructions to Transfer Agent. On or prior to the Closing Date, the Company shall execute and deliver irrevocable written instructions to the transfer agent for its Common Stock (the “Transfer Agent”), and provide each Investor with a copy thereof, directing the Transfer Agent (i) to issue certificates representing Warrant Shares upon exercise of the Warrants and (ii) to deliver such certificates to such Investor no later than the close of business on the third (3rd) business day following the related Exercise Date (as defined in the Warrants), as the case may be. Such certificates may bear legends pursuant to applicable provisions of this Agreement or applicable law. The Company shall instruct the transfer agent that, in lieu of delivering physical certificates representing shares of Common Stock to an Investor upon exercise of the Warrants, and as long as the Transfer Agent is a participant in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer program, and such Investor has not informed the Company that it wishes to receive physical certificates therefor, and no legend is

required to appear on any physical certificate if issued, the transfer agent shall effect delivery of Warrant Shares by crediting the account of such Investor or its nominee at DTC for the number of shares for which delivery is required hereunder within the time frame specified above for delivery of certificates. The Company represents to and agrees with each Investor that it will not give any instruction to the Transfer Agent that will conflict with the foregoing instruction or otherwise restrict such Investor’s right to exercise the Warrant or to receive Warrant Shares upon exercise of the Warrants. In the event that the Company’s relationship with the Transfer Agent should be terminated for any reason, the Company shall use its reasonable best efforts to cause the Transfer Agent to continue acting as transfer agent pursuant to the terms hereof until such time that a successor transfer agent is appointed by the Company and receives the instructions described above.

4.8 Limitations on Disposition. No Investor shall sell, transfer, assign or dispose of any Securities, unless:

(a) there is then in effect an effective registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or

(b) such Investor has notified the Company in writing of any such disposition, and furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such Securities under the Securities Act; provided, however, that no such opinion of counsel will be required (A) if the sale, transfer or assignment is made to an Affiliate of such Investor, or (B) in connection with a bona fide pledge or hypothecation of any Securities under a margin arrangement with a broker-dealer or other financial institution or the sale of any such Securities by such broker-dealer or other financial institution following such Investor’s default under such margin arrangement.

4.9 Disclosure of Non-public Information. The Company agrees that it will not at any time following the Execution Date disclose material non-public information to any Investor without first obtaining such Investor’s written consent to such disclosure.

4.10 Listing. The Company has, or promptly following the Closing shall, use its commercially reasonable efforts to include all of the Shares and all of the Warrant Shares issuable upon exercise of the Warrants (without regard to any limitation on such conversion or exercise) for listing on the Nasdaq Global Market.

4.11 Restriction on Issuances. During the period beginning on the Execution Date and ending on the date that is ninety (90) days after the Effective Date, the Company will not, directly or indirectly, effect a Subsequent Placement.

4.12 Indemnification of Investors. The Company will indemnify and hold each Investor and its directors, managers, officers, shareholders, members, partners, employees and agents (each, an “Investor Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any such Investor Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents or (b) any action instituted against an Investor, or any of them or their respective Affiliates, by any shareholder of the Company who is not an Affiliate of such Investor, with respect to any of the transactions contemplated by the Transaction Documents (unless such action is based upon a breach of such Investor’s representations, warranties or covenants under the Transaction Documents or any agreements or understandings such

Investor may have with any such shareholder or any violations by such Investor of state or federal securities laws or any conduct by such Investor which constitutes fraud, gross negligence, willful misconduct or malfeasance). If any action shall be brought against any Investor Party in respect of which indemnity may be sought pursuant to this Agreement, such Investor Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing. Any Investor Party shall have the right to engage separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Investor Party except to the extent that (i) the engagement thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time following such Investor Party’s written request that it do so, to assume such defense and to engage counsel or (iii) in such action there is, in the reasonable opinion of such separate counsel, a material conflict on any material issue between the position of the Company and the position of such Investor Party. The Company will not be liable to any Investor Party under this Agreement (i) for any settlement by an Investor Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (ii) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to such Investor Party’s wrongful actions or omissions, or gross negligence or to such Investor Party’s breach of any of the representations, warranties, covenants or agreements made by such Investor in this Agreement or in the other Transaction Documents.

6. MISCELLANEOUS.

6.1 Survival; Severability. The representations, warranties, covenants and indemnities made by the parties herein and in the other Transaction Documents shall survive the Closing (provided that such representations and warranties shall survive only for a period of two years after the Closing), notwithstanding any due diligence investigation made by or on behalf of the party seeking to rely thereon. In the event that any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Agreement shall continue in full force and effect without said provision; provided that in such case the parties shall negotiate in good faith to replace such provision with a new provision which is not illegal, unenforceable or void, as long as such new provision does not materially change the economic benefits of this Agreement to the parties.

6.2 Successors and Assigns. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors and permitted assigns of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and permitted assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. The Investors may assign their respective rights and obligations hereunder, in connection with any private sale or transfer of the Shares or Warrants in accordance with the terms hereof, as long as, as a condition precedent to such transfer, the transferee executes an acknowledgment agreeing to be bound by the applicable provisions of this Agreement, in which case the term “Investor” shall be deemed to refer to such transferee as though such transferee were an original signatory hereto. The Company may not assign its rights or obligations under this Agreement without the written consent of each Investor.

6.3 No Reliance. Each party acknowledges that (i) it has such knowledge in business and financial matters as to be fully capable of evaluating this Agreement, the other Transaction Documents and the transactions contemplated hereby and thereby, (ii) it is not relying on any advice or representation of any other party in connection with entering into this Agreement, the other Transaction Documents or such transactions (other than the representations made in this Agreement or the other Transaction Documents), (iii) it has not received from any other party any assurance or guarantee as to the merits (whether legal, regulatory, tax, financial or otherwise) of entering into this Agreement or the other Transaction Documents or the performance of its obligations hereunder and thereunder, and (iv) it has consulted with its own legal, regulatory, tax, business, investment, financial and accounting advisors to the extent that it has deemed necessary, and has entered into this Agreement and the other Transaction Documents based on its own independent judgment and on the advice of its advisors as it has deemed necessary, and not on any view (whether written or oral) expressed by any other party.

6.4 Independent Nature of Investors’ Obligations and Rights. The obligations of each Investor hereunder are several and not joint with the obligations of the other Investors hereunder, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor hereunder, or is relying upon the advice or assistance of any other Investor. The Company acknowledges and agrees that nothing contained herein or in any other agreement or document delivered at Closing, and no action taken by any Investor pursuant hereto or thereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or a “group” as described in Section 13(d) of the Exchange Act, or create a presumption that the Investors are in any way acting in concert with respect to such obligations or the transactions contemplated by this Agreement. Each

Investor has been represented by its own separate counsel in connection with the transactions contemplated hereby, shall be entitled to protect and enforce its rights, including without limitation rights arising out of this Agreement or the other Transaction Documents, individually, and shall not be required to be join any other Investor as an additional party in any proceeding for such purpose.

6.5 Investors’ Trading Activity. The Company acknowledges that, following the Closing and the press release described in Section 4.1 of this Agreement, each Investor shall have the right to purchase or sell, long or short, Common Stock and instruments or contracts whose value is derived from the market value of the Common Stock, and that sales of or certain derivative transactions relating to the Common Stock may have a negative impact on the market price of the Common Stock.

6.6 Injunctive Relief. The Company acknowledges and agrees that a breach by it of its obligations hereunder will cause irreparable harm to each Investor and that the remedy or remedies at law for any such breach will be inadequate and agrees, in the event of any such breach, in addition to all other available remedies, such Investor shall be entitled to an injunction restraining any breach and requiring immediate and specific performance of such obligations without the necessity of showing economic loss or the posting of any bond.

6.7 Governing Law; Jurisdiction. This Agreement shall be governed by and construed under the laws of the State of California applicable to contracts made and to be performed entirely within the State of California. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City and County of San Francisco for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law.

6.8 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, and all of which together shall constitute one and the same instrument. This Agreement may be executed and delivered by facsimile transmission.

(2) The Company has the requisite corporate power and authority to enter into and perform its obligations under the Transaction Documents, and to offer and sell the Securities, in accordance with the terms of the Transaction Documents. The execution and delivery of the Transaction Documents, and the performance of its obligations under the Transaction Documents, have been duly authorized by all necessary corporate action on the part of the Company. Each of the Transaction Documents has been duly executed and delivered, and constitute valid and binding obligations of the Company enforceable against the Company in accordance with their respective terms.

The Shares, when issued, sold and delivered against payment therefor in accordance with the provisions of the Purchase Agreement, and the Warrant Shares, when issued and paid for in accordance with the terms of the Warrant, will be validly issued, fully paid and non-assessable, and the issuance of the Shares and the Warrant Shares will not be subject to any preemptive rights under the Delaware General Corporation Law (“DGCL”), the Company’s Certificate or Bylaws or any material contract to which the Company is a party and which has been filed by the Company or incorporated by reference as an exhibit to its Annual Report on Form 10-K for the fiscal year ended December 31, 2005 (the “2005 10-K”), or any other report filed by the Company with the SEC under Section 13 of the Exchange Act since the filing by the Company of the 2005 10-K.
