AGREEMENT

The parties to this Agreement, intending to be legally bound, agree as follows:

Section 1. DESCRIPTION OF TRANSACTION

1.1 Structure of the Merger.

(a) Merger of Merger Sub into Merger Partner. Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time (as defined in Section 1.3), Merger Sub shall be merged with and into Merger Partner, and the separate existence of Merger Sub shall cease. Merger Partner will continue as the surviving corporation in the Merger (the “Surviving Corporation”).

(b) Alternative Structure. If all of the conditions to the Merger, except for the conditions set forth in Section 7.4(a) and Section 8.4(a) (the “Tax Opinion Conditions”), have been satisfied or waived, and the Tax Opinion Conditions could be satisfied if, immediately following the Merger, as part of one integrated plan for U.S. federal income tax purposes, the Surviving Corporation were merged in accordance with Delaware law into a limited liability company wholly-owned by Pivot that is disregarded as an entity separate from its owner for U.S. federal income tax purposes (the “LLC”) with the LLC surviving (such merger, the “Second Merger”), then the Second Merger shall be consummated; provided, however, that (i) the LLC shall become a party to, and shall become bound by, the terms of this Agreement and (ii) the Tax Representation Letters shall be executed and delivered. If the Second Merger occurs, references to the Merger in Recital B, Section 1.11, Section 2.12(n), Section 3.10(n), and Section 5 shall be to the Merger and the Second Merger, taken together as one integrated transaction for U.S. federal income tax purposes.

1.2 Effects of the Merger. The Merger shall have the effects set forth in this Agreement and in the applicable provisions of the DGCL. As a result of the Merger, Merger Partner will become a wholly-owned subsidiary of Pivot.

1.3 Closing; Effective Time. Unless this Agreement is earlier terminated pursuant to the provisions of Section 9.1 of this Agreement, and subject to the satisfaction or waiver of the conditions set forth in Sections 6, 7 and 8 of this Agreement, the consummation of the Merger (the “Closing”) shall take place at the offices of Latham & Watkins LLP, 140 Scott Drive, Menlo Park, California, as promptly as practicable (but in no event later than the third Business Day following the satisfaction or waiver of the last to be satisfied or waived of the conditions set forth in Sections 6, 7 and 8, other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of each of such conditions), or at such other time, date and place as Pivot and Merger Partner may mutually agree in writing. The date on which the Closing actually takes place is referred to as the “Closing Date.” At the Closing, the Parties hereto shall cause the Merger to be consummated by executing and filing with the Secretary of State of the State of Delaware a Certificate of Merger with respect to the Merger, satisfying the applicable requirements of the DGCL and in a form reasonably acceptable to Pivot and Merger Partner. The Merger shall become effective at the time of the filing of such Certificate of Merger with the Secretary of State of the State of Delaware or at such later time as may be specified in such Certificate of Merger with the consent of Merger Partner (the time as of which the Merger becomes effective being referred to as the “Effective Time”).

1.4 Certificate of Incorporation and Bylaws; Directors and Officers. At the Effective Time:

(a) the Certificate of Incorporation of the Surviving Corporation shall be amended and restated in its entirety to read identically to the Certificate of Incorporation of Merger Sub as in effect immediately prior to the Effective Time, until thereafter amended as provided by the DGCL and such Certificate of Incorporation;

(b) the Certificate of Incorporation of Pivot shall be the Certificate of Incorporation of Pivot immediately prior to the Effective Time, until thereafter amended as provided by the DGCL and such Certificate of Incorporation; provided, however, that at the Effective Time, Pivot shall file an amendment to its certificate of incorporation to change the name of Pivot to “Transcept Pharmaceuticals, Inc.;”

(c) the Bylaws of the Surviving Corporation shall be amended and restated in its entirety to read identically to the Bylaws of Merger Sub as in effect immediately prior to the Effective Time, until thereafter amended as provided by the DGCL and such Bylaws;

(d) the directors and officers of Pivot shall be as set forth in Section 5.17; and

(e) the directors and officers of the Surviving Corporation, each to hold office in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation, shall be the directors and officers of Pivot as set forth in Section 5.17, after giving effect to the provisions of Section 5.17.

1.5 Conversion of Shares and Issuance of Warrants.

(a) At the Effective Time, by virtue of the Merger and without any further action on the part of Pivot, Merger Sub, Merger Partner or any stockholder of Merger Partner:

(i) any shares of Merger Partner Common Stock or Merger Partner Preferred Stock held as treasury stock or held or owned by Merger Partner, Merger Sub or any Subsidiary of Merger Partner immediately prior to the Effective Time shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor;

(ii) Merger Partner shall have taken such action to effect a conversion of Merger Partner Series A Preferred Stock, Merger Partner Series B Preferred Stock, Merger Partner Series C Preferred Stock and Merger Partner Series D Preferred Stock (collectively, the “Merger Partner Preferred Stock”) to be converted into Common Stock immediately prior to the Effective Time (the “Preferred Stock Conversion”); and

(iii) subject to Section 1.5(c), each share of Merger Partner Common Stock outstanding immediately prior to the Effective Time (excluding shares to be canceled pursuant to Section 1.5(a)(i) and excluding Dissenting Shares) shall be converted solely into the right to receive a number of shares of Pivot Common Stock equal to the Exchange Ratio.

(b) If any shares of Merger Partner Common Stock outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option or the risk of forfeiture or under any applicable restricted stock purchase agreement or other agreement with Merger Partner, then the shares of Pivot Common Stock issued in exchange for such shares of Merger Partner Common Stock will to the same extent be unvested and subject to the same repurchase option or risk of forfeiture, and the certificates representing such shares of Pivot Common Stock shall accordingly be marked with appropriate legends. Merger Partner shall take all action that may be necessary to ensure that, from and after the Effective Time, Pivot is entitled to exercise any such repurchase option or other right set forth in any such restricted stock purchase agreement or other agreement.

(c) No fractional shares of Pivot Common Stock shall be issued in connection with the Merger, and no certificates or scrip for any such fractional shares shall be issued. Any holder of Merger Partner Common Stock who would otherwise be entitled to receive a fraction of a share of Pivot Common Stock (after aggregating all fractional shares of Pivot Common Stock issuable to such holder) shall, in lieu of such fraction of a share and upon surrender of such holder’s Merger Partner Stock Certificate(s) (as defined in Section 1.7), be paid in cash the dollar amount (rounded to the nearest whole cent), without interest, determined by multiplying such fraction by the closing price of a share of Pivot Common Stock on The NASDAQ Global Market (or such other NASDAQ market on which the Pivot Common Stock then trades) on the date the Merger becomes effective.

(d) All Merger Partner Options outstanding immediately prior to the Effective Time under the Merger Partner Stock Option Plan and all Merger Partner Warrants outstanding immediately prior to the Effective Time shall be exchanged for options to purchase Pivot Common Stock or warrants to purchase Pivot Common Stock, as applicable, in accordance with Section 5.5.

(e) Each share of Common Stock, $0.0001 par value per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and nonassessable share of Common Stock, $0.0001 par value per share, of the Surviving Corporation. Each stock certificate of Merger Sub evidencing ownership of any such shares shall, as of the Effective Time, evidence ownership of such shares of Common Stock of the Surviving Corporation.

(f) If, between the date of this Agreement and the Effective Time, the outstanding shares of Merger Partner Capital Stock or Pivot Common Stock shall have been changed into, or exchanged for, a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares, the Exchange Ratio shall be correspondingly adjusted to provide the holders of Merger Partner Common Stock, Merger Partner Preferred Stock, Merger Partner Options and Merger Partner Warrants the same economic effect as contemplated by this Agreement prior to such event.

1.6 Calculation of Net Cash.

(a) For the purposes of this Agreement, the “Determination Date” shall be the date that is ten (10) calendar days prior to the anticipated date for Closing, as agreed upon by Pivot and Merger Partner at least ten (10) calendar days prior to the Pivot Stockholders Meeting (the “Anticipated Closing Date”); provided, that, notwithstanding the foregoing, if the Form S-4 Registration Statement is not filed on or before October 5, 2008, then the “Determination Date” shall be December 31, 2008. Merger Partner shall reasonably cooperate with Pivot and provide Pivot, and require its Representatives, advisors, accountants and attorneys to provide, Pivot and its Representatives, advisors, accountants and attorneys, with all true, correct and complete information regarding Merger Partner that is required by law to be included in the Form S-4 Registration Statement or reasonably requested from Merger Partner to be included in the Form S-4 Registration Statement. On the fifth calendar day after the Determination Date, Pivot shall deliver to Merger Partner a schedule (an “Estimated Net Cash Schedule”) setting forth, in reasonable detail, Pivot’s calculation of Net Cash (using an estimate of Pivot’s accounts payable and accrued expenses, in each case as of such date and determined in a manner substantially consistent with the manner in which such items were determined for Pivot’s most recent SEC filings) (the “Net Cash Calculation”) as of such applicable Determination Date prepared by Pivot’s Chief Financial Officer. Within five (5) calendar days following the Determination Date, Pivot shall deliver to Merger Partner a schedule (a “Final Net Cash Schedule”) setting forth the Net Cash Calculation as of such Determination Date prepared by Pivot. Pivot shall make the work papers and back-up materials used in preparing the applicable Estimated Net Cash Schedule and Final Net Cash Schedule available to Merger Partner and, if requested by Merger Partners, its accountants and counsel at reasonable times and upon reasonable notice.

(b) Within three (3) calendar days after Pivot delivers the applicable Estimated Net Cash Schedule or Final Net Cash Schedule (a “Response Date”), Merger Partner shall have the right to dispute any part of such Estimated Net Cash Schedule or Final Net Cash Schedule by delivering a written notice to that effect to Pivot (a “Dispute Notice”). Any Dispute Notice shall identify in reasonable detail the nature of any proposed revisions to the applicable Net Cash Calculation.

(c) If on or prior to any Response Date, (i) Merger Partner notifies Pivot in writing that it has no objections to the applicable Net Cash Calculation or (ii) Merger Partner fails to deliver a Dispute Notice as provided in Section 1.6(b), then the Net Cash Calculation as set forth in the applicable Estimated Net Cash Schedule or Final Net Cash Schedule shall be deemed to have been finally determined for purposes of this Agreement and to represent the Net Cash at the Determination Date for purposes of this Agreement.

(d) If Merger Partner delivers a Dispute Notice on or prior to the applicable Response Date, then Representatives of Pivot and Merger Partner shall promptly meet and attempt in good faith to resolve the disputed item(s) and negotiate an agreed-upon determination of Net Cash, which agreed upon Net Cash amount shall be deemed to have been finally determined for purposes of this Agreement and to represent the Net Cash at the Determination Date for purposes of this Agreement.

(e) If Representatives of Pivot and Merger Partner are unable to negotiate an agreed-upon determination of Net Cash at a Determination Date pursuant to Section 1.6(d) within three (3) calendar days after delivery of the applicable Dispute Notice (or such other period as Pivot and Merger Partner may mutually agree upon), then Pivot and Merger Partner shall jointly select an independent auditor of recognized national standing (the “Accounting Firm”) to resolve any remaining disagreements as to the Net Cash Calculation. Pivot shall promptly deliver to the Accounting Firm the work papers and back-up materials used in preparing the applicable Estimated Net Cash Schedule or Final Net Cash Schedule, and Pivot and Merger Partner shall use their best efforts to cause the Accounting Firm to make its determination within ten (10) calendar days of accepting its selection. Merger Partner and Pivot shall be afforded the opportunity to present to the Accounting Firm any material related to the unresolved disputes and to discuss the issues with the Accounting Firm; provided, however, that no such presentation or discussion shall occur without the presence of a Representative of each of Merger Partner and Pivot. The determination of the Accounting Firm shall be limited to the disagreements submitted to the Accounting Firm. The determination of the amount of Net Cash made by the Accounting Firm shall be deemed to have been finally determined for purposes of this Agreement and to represent the Net Cash at the Determination Date for purposes of this Agreement, and the Parties shall delay the Closing until the resolution of the matters described in this Section 1.6(e). The fees and expenses of the Accounting Firm shall be allocated between Pivot and Merger Partner in the same proportion that the disputed amount of the Net Cash that was unsuccessfully disputed by such Party (as finally determined by the Accounting Firm) bears to the total disputed amount of the Net Cash amount. If this Section 1.6(e) applies as to the determination of the Net Cash at the Determination Date described in Section 1.6(a), upon resolution of the matter in accordance with this Section 1.6(e), the Parties shall not be required to determine Net Cash again even though the Closing Date may occur later than the Anticipated Closing Date.

1.7 Closing of Merger Partner’s Transfer Books. At the Effective Time: (a) all shares of Merger Partner Common Stock and Merger Partner Preferred Stock outstanding immediately prior to the Effective Time shall automatically be canceled and retired and shall cease to exist, and all holders of certificates representing shares of Merger Partner Common Stock and Merger Partner Preferred Stock that were outstanding immediately prior to the Effective Time shall cease to have any rights as stockholders of Merger Partner; and (b) the stock transfer books of Merger Partner shall be closed with respect to all shares of Merger Partner Common Stock and Merger Partner Preferred Stock outstanding immediately prior to the Effective Time. No further transfer of any such shares of Merger Partner Common Stock shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any shares of Merger Partner Common Stock outstanding immediately prior to the Effective Time (a “Merger Partner Stock Certificate”) is presented to the Exchange Agent (as defined in Section 1.8) or to the Surviving Corporation, such Merger Partner Stock Certificate shall be canceled and shall be exchanged as provided in Sections 1.5 and 1.8.

1.8 Surrender of Certificates.

(a) On or prior to the Closing Date, Pivot and Merger Partner shall agree upon and select a reputable bank, transfer agent or trust company to act as exchange agent in the Merger (the “Exchange Agent”). At the Effective Time, Pivot shall deposit with the Exchange Agent: (i) certificates representing the shares of Pivot Common Stock issuable pursuant to Section 1.5(a) and (ii) cash sufficient to make payments in lieu of fractional shares in accordance with Section 1.5(c). The shares of Pivot Common Stock and cash amounts so deposited with the Exchange Agent, together with any dividends or distributions received by the Exchange Agent with respect to such shares, are referred to collectively as the “Exchange Fund.”

(b) At or before the Effective Time, Merger Partner will deliver to Pivot a true, complete and accurate listing of all record holders of Merger Partner Stock Certificates at the Effective Time, including the number and class of shares of Merger Partner’s capital stock held by such record holder and the number of shares of Pivot Common Stock such holder is entitled to receive pursuant to Section 1.5. Promptly after the Effective Time, the Parties shall cause the Exchange Agent to mail to the Persons who were record holders of Merger Partner Stock Certificates immediately prior to the Effective Time: (i) a letter of transmittal in customary form and containing such provisions as Pivot may reasonably specify (including a provision confirming that delivery

of Merger Partner Stock Certificates shall be effected, and risk of loss and title to Merger Partner Stock Certificates shall pass, only upon delivery of such Merger Partner Stock Certificates to the Exchange Agent); and (ii) instructions for use in effecting the surrender of Merger Partner Stock Certificates in exchange for certificates representing Pivot Common Stock. Upon surrender of a Merger Partner Stock Certificate to the Exchange Agent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably required by the Exchange Agent or Pivot: (A) the holder of such Merger Partner Stock Certificate shall be entitled to receive in exchange therefor a certificate representing the number of whole shares of Pivot Common Stock that such holder has the right to receive pursuant to the provisions of Section 1.5(a) (and cash in lieu of any fractional share of Pivot Common Stock); and (B) the Merger Partner Stock Certificate so surrendered shall be canceled. Until surrendered as contemplated by this Section 1.8(b), each Merger Partner Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive shares of Pivot Common Stock (and cash in lieu of any fractional share of Pivot Common Stock). If any Merger Partner Stock Certificate shall have been lost, stolen or destroyed, Pivot may, in its discretion and as a condition precedent to the delivery of any shares of Pivot Common Stock and in the case of Merger Partner Certificates representing Merger Partner Preferred Stock, require the owner of such lost, stolen or destroyed Merger Partner Stock Certificate to provide an applicable affidavit with respect to such Merger Partner Stock Certificate and post a bond indemnifying Pivot against any claim suffered by Pivot related to the lost, stolen or destroyed Merger Partner Stock Certificate or any Pivot Common Stock issued in exchange therefor as Pivot may reasonably request.

(c) No dividends or other distributions declared or made with respect to Pivot Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Merger Partner Stock Certificate with respect to the shares of Pivot Common Stock that such holder has the right to receive in the Merger until such holder surrenders such Merger Partner Stock Certificate in accordance with this Section 1.8 (at which time such holder shall be entitled, subject to the effect of applicable abandoned property, escheat or similar laws, to receive all such dividends and distributions, without interest).

(d) Any portion of the Exchange Fund that remains undistributed to holders of Merger Partner Stock Certificates as of the date 180 days after the Closing Date shall be delivered to Pivot upon demand, and any holders of Merger Partner Stock Certificates who have not theretofore surrendered their Merger Partner Stock Certificates in accordance with this Section 1.8 shall thereafter look only to Pivot for satisfaction of their claims for Pivot Common Stock, cash in lieu of fractional shares of Pivot Common Stock and any dividends or distributions with respect to shares of Pivot Common Stock.

(e) Each of the Exchange Agent, Pivot and the Surviving Corporation shall be entitled to deduct and withhold from any consideration deliverable pursuant to this Agreement to any holder of any Merger Partner Stock Certificate such amounts as are required to be deducted or withheld from such consideration under the Code or under any other applicable Legal Requirement and shall be entitled to request any reasonably appropriate Tax forms, including Form W-9 (or the appropriate Form W-8, as applicable) from any recipient of payments hereunder. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

(f) No party to this Agreement shall be liable to any holder of any Merger Partner Stock Certificate or to any other Person with respect to any shares of Pivot Common Stock (or dividends or distributions with respect thereto) or for any cash amounts, delivered to any public official pursuant to any applicable abandoned property law, escheat law or similar Legal Requirement.

1.9 Appraisal Rights.

(a) Notwithstanding any provision of this Agreement to the contrary, shares of Merger Partner Capital Stock that are outstanding immediately prior to the Effective Time and which are held by stockholders who have exercised and perfected appraisal rights for such shares of Merger Partner Capital Stock in accordance with the DGCL and/or Chapter 13 of the California General Corporation Law (the “CGCL”) (collectively, the

“Dissenting Shares”) shall not be converted into or represent the right to receive the per share amount of the merger consideration described in Section 1.5 attributable to such Dissenting Shares. Such stockholders shall be entitled to receive payment of the appraised value of such shares of Merger Partner Capital Stock held by them in accordance with the DGCL or the CGCL, unless and until such stockholders fail to perfect or effectively withdraw or otherwise lose their appraisal rights under the DGCL or CGCL. All Dissenting Shares held by stockholders who shall have failed to perfect or who effectively shall have withdrawn or lost their right to appraisal of such shares of Merger Partner Capital Stock under the DGCL or CGCL shall thereupon be deemed to be converted into and to have become exchangeable for, as of the Effective Time, the right to receive the per share amount of the merger consideration attributable to such Dissenting Shares upon their surrender in the manner provided in Section 1.5.

(b) Merger Partner shall give Pivot prompt written notice of any demands by dissenting stockholders received by Merger Partner, withdrawals of such demands and any other instruments served on Merger Partner and any material correspondence received by Merger Partner in connection with such demands.

1.10 Further Action. If, at any time after the Effective Time, any further action is determined by the Surviving Corporation to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of Merger Partner, then the officers and directors of the Surviving Corporation shall be fully authorized, and shall use their commercially reasonable efforts (in the name of Merger Partner, in the name of Merger Sub and otherwise) to take such action.

1.11 Tax Consequences. For federal income tax purposes, the Merger is intended to constitute a reorganization within the meaning of Section 368(a) of the Code and the Treasury Regulations promulgated thereunder. The parties to this Agreement adopt this Agreement as a “plan of reorganization” within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the Treasury Regulations.

Section 2. REPRESENTATIONS AND WARRANTIES OF MERGER PARTNER

Merger Partner represents and warrants to Pivot and Merger Sub as follows, except as set forth in the written disclosure schedule delivered by Merger Partner to Pivot (the “Merger Partner Disclosure Schedule”). The Merger Partner Disclosure Schedule shall be arranged in sections and subsections corresponding to the numbered and lettered sections and subsections contained in this Section 2. The disclosures in any section or subsection of the Merger Partner Disclosure Schedule shall qualify other sections and subsections in this Section 2 to the extent it is reasonably clear from a reading of the disclosure that such disclosure is applicable to such other sections and subsections. The inclusion of any information in the Merger Partner Disclosure Schedule (or any update thereto) shall not be deemed to be an admission or acknowledgment, in and of itself, that such information is required by the terms hereof to be disclosed, is material, has resulted in or would result in a Merger Partner Material Adverse Effect, or is outside the Ordinary Course of Business.

2.1 Subsidiaries; Due Organization; Etc.

(a) Merger Partner has no Subsidiaries, except for the Entities identified in Part 2.1(a) of the Merger Partner Disclosure Schedule; and neither Merger Partner nor any of the other Entities identified in Part 2.1(a) of the Merger Partner Disclosure Schedule owns any capital stock of, or any equity interest of any nature in, any other Entity, other than the Entities identified in Part 2.1(a) of the Merger Partner Disclosure Schedule. Merger Partner has not agreed nor is obligated to make, nor is bound by any Contract under which it may become obligated to make, any future investment in or capital contribution to any other Entity.

(b) Each of Merger Partner and the Merger Partner Subsidiaries is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation and has all necessary power and authority: (i) to conduct its business in the manner in which its business is currently being conducted; (ii) to own and use its assets in the manner in which its assets are currently owned and used; and (iii) to perform its obligations under all Contracts by which it is bound.

(c) Each of Merger Partner and the Merger Partner Subsidiaries is qualified to do business as a foreign corporation, and is in good standing, under the laws of all jurisdictions where the nature of its business requires such qualification other than in jurisdictions where the failure to be so qualified individually or in the aggregate would not be reasonably expected to have a Merger Partner Material Adverse Effect.

2.2 Certificate of Incorporation; Bylaws; Charters and Codes of Conduct. Merger Partner has delivered to Pivot accurate and complete copies of the certificate of incorporation, bylaws and other charter and organizational documents, including all currently effective amendments thereto for Merger Partner and each Merger Partner Subsidiary. Part 2.2 of the Merger Partner Disclosure Schedule lists, and Merger Partner has delivered to Pivot, accurate and complete copies of: (a) the charters of all committees of Merger Partner’s board of directors; and (b) any code of conduct or similar policy adopted by Merger Partner or by the board of directors, or any committee of the board of directors, of Merger Partner. Neither Merger Partner nor any Merger Partner Subsidiary has taken any action in breach or violation of any of the provisions of its certificate of incorporation, bylaws and other charter and organizational documents nor is in breach or violation of any of the material provisions of their respective certificates of incorporation, bylaws and other charter and organizational documents, except as would not reasonably be expected to have, individually or in the aggregate, a Merger Partner Material Adverse Effect.

(a) The authorized capital stock of Merger Partner consists of (i) 66,000,000 shares of Merger Partner Common Stock, par value $0.001 per share, of which 3,528,961 shares have been issued and are outstanding as of the date of this Agreement, (ii) 426,008 shares of Series A Preferred Stock, par value $0.001 per share of which 426,008 shares have been issued and are outstanding; (iii) 7,966,748 shares of Series B Preferred Stock, par value $0.001 per share of which 7,966,748 shares have been issued and are outstanding; (iv) 21,300,000 shares of Series C Preferred Stock, par value $0.001 per share of which 20,079,889 shares have been issued and are outstanding; and (v) 24,029,412 shares of Series D Preferred Stock, par value $0.001 per share of which 23,529,410 shares have been issued and are outstanding.

Preferred Stock filed an election under Section 83(b) of the Code with respect to such Merger Partner Common Stock or Merger Partner Preferred Stock within thirty (30) days of purchase. Each share of Merger Partner Preferred Stock is convertible into one share of Merger Partner Common Stock.

(b) Except for the Merger Partner Amended and Restated 2002 Stock Option Plan (the “Merger Partner Stock Option Plan”), Merger Partner does not have any stock option plan or any other plan, program, agreement or arrangement providing for any equity-based compensation for any Person.

Pivot shall not withdraw or modify in a manner adverse to Merger Partner the Pivot Board Recommendation unless specifically permitted pursuant to the terms of Section 5.3(b).

5.4 Regulatory Approvals. Each Party shall use commercially reasonable efforts to file or otherwise submit, as soon as practicable after the date of this Agreement, all applications, notices, reports and other documents reasonably required to be filed by such Party with or otherwise submitted by such Party to any Governmental Body with respect to the Merger and the other Contemplated Transactions, and to submit promptly any additional information requested by any such Governmental Body.

Merger Partner and Pivot shall respond as promptly as is practicable to respond in compliance with: (i) any inquiries or requests received from the Federal Trade Commission or the Department of Justice for additional information or documentation; and (ii) any inquiries or requests received from any state attorney general, foreign antitrust or competition authority or other Governmental Body in connection with antitrust or competition matters.

5.5 Merger Partner Options and Warrants.

(a) Subject to Section 5.5(c), at the Effective Time, each Merger Partner Option that is outstanding and unexercised immediately prior to the Effective Time, whether or not vested, shall be converted into and become an option to purchase Pivot Common Stock, and Pivot shall assume the Merger Partner Stock Option Plan each such Merger Partner Option in accordance with the terms (as in effect as of the date of this Agreement) of the Merger Partner Stock Option Plan was issued and the terms of the stock option agreement by which such Merger Partner Option is evidenced. All rights with respect to Merger Partner Common Stock under Merger Partner Options assumed by Pivot shall thereupon be converted into rights with respect to Pivot Common Stock. Accordingly, from and after the Effective Time: (i) each Merger Partner Option assumed by Pivot may be exercised solely for shares of Pivot Common Stock; (ii) the number of shares of Pivot Common Stock subject to each Merger Partner Option assumed by Pivot shall be determined by multiplying (A) the number of shares of Merger Partner Common Stock that were subject to such Merger Partner Option, as in effect immediately prior to the Effective Time by (B) the Exchange Ratio and rounding the resulting number down to the nearest whole number of shares of Pivot Common Stock; (iii) the per share exercise price for the Pivot Common Stock issuable upon exercise of each Merger Partner Option assumed by Pivot shall be determined by dividing (A) the per share exercise price of Merger Partner Common Stock subject to such Merger Partner Option, as in effect immediately prior to the Effective Time, by (B) the Exchange Ratio and rounding the resulting exercise price up to the nearest whole cent; and (iv) any restriction on the exercise of any Merger Partner Option assumed by Pivot shall continue in full force and effect and the term, exercisability, vesting schedule and other provisions of such Merger Partner Option shall otherwise remain unchanged; provided, however, that: (A) to the extent provided under the terms of a Merger Partner Option, such Merger Partner Option assumed by Pivot in accordance with this Section 5.5(a) shall, in accordance with its terms, be subject to further adjustment as appropriate to reflect any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction with respect to Pivot Common Stock subsequent to the Effective Time; and (B) Pivot’s Board of Directors or a committee thereof shall succeed to the authority and

responsibility of Merger Partner’s Board of Directors or any committee thereof with respect to each Merger Partner Option assumed by Pivot. Notwithstanding anything to the contrary in this Section 5.5(a), the conversion of each Merger Partner Option (regardless of whether such option qualifies as an “incentive stock option” within the meaning of Section 422 of the Code) into an option to purchase shares of Pivot Common Stock shall be made in a manner consistent with Treasury Regulation Section 1.424-1, such that the conversion of a Merger Partner Option shall not constitute a “modification” of such Merger Partner Option for purposes of Section 409A or Section 424 of the Code.

(b) Pivot shall file with the SEC, no later than 60 days after the Effective Time, a registration statement on Form S-8, if available for use by Pivot, relating to the shares of Pivot Common Stock issuable with respect to Merger Partner Options assumed by Pivot in accordance with Section 5.5(a).

(c) Subject to Section 5.5(d), at the Effective Time, each Merger Partner Warrant that is outstanding and unexercised immediately prior to the Effective Time, shall become converted into and become a warrant to purchase Pivot Common Stock and Pivot shall assume each such Merger Partner Warrant in accordance with its terms. All rights with respect to Merger Partner Common Stock or Merger Partner Preferred Stock under Merger Partner Warrants assumed by Pivot shall thereupon be converted into rights with respect to Pivot Common Stock. Accordingly, from and after the Effective Time: (i) each Merger Partner Warrant assumed by Pivot may be exercised solely for shares of Pivot Common Stock; (ii) the number of shares of Pivot Common Stock subject to each Merger Partner Warrant assumed by Pivot shall be determined by multiplying (A) the number of shares of Merger Partner Common Stock, or the number of shares of Merger Partner Common Stock issuable upon conversion of the shares of Merger Partner Preferred Stock issuable upon exercise of the Merger Partner Warrant, as applicable, that were subject to such Merger Partner Warrant immediately prior to the Effective Time by (B) the Exchange Ratio and rounding the resulting number down to the nearest whole number of shares of Pivot Common Stock; (iii) the per share exercise price for the Pivot Common Stock issuable upon exercise of each Merger Partner Warrant assumed by Pivot shall be determined by dividing the effective per share exercise price of Merger Partner Common Stock or Merger Partner Preferred Stock, subject to such Merger Partner Warrant, as in effect immediately prior to the Effective Time, by the Exchange Ratio and rounding the resulting exercise price up to the nearest whole cent; and (iv) any restriction on any Merger Partner Warrant assumed by Pivot shall continue in full force and effect and the term and other provisions of such Merger Partner Warrant shall otherwise remain unchanged.

(d) Prior to the Effective Time, Merger Partner shall take all actions that may be necessary (under the Merger Partner Stock Option Plan, the Merger Partner Warrants and otherwise) to effectuate the provisions of this Section 5.5 and to ensure that, from and after the Effective Time, holders of Merger Partner Options and Merger Partner Warrants have no rights with respect thereto other than those specifically provided in this Section 5.5.

5.6 Employee Benefits. Pivot and Merger Partner shall cause Pivot to comply with terms of any employment, severance, retention, change of control, or similar agreement specified on Part 3.11(c) of the Pivot Disclosure Schedule as being applicable to this Section 5.6, as of the date of this Agreement, subject to the provisions of such agreements, including the maintenance of COBRA insurance for Pivot’s former officers and employees.

5.7 Indemnification of Officers and Directors.

(a) From the Effective Time through the sixth anniversary of the date on which the Effective Time occurs, each of Pivot and the Surviving Corporation shall, jointly and severally, indemnify and hold harmless each person who is now, or has been at any time prior to the date hereof, or who becomes prior to the Effective Time, a director or officer of Pivot or Merger Partner (the “D&O Indemnified Parties”), against all claims, losses, liabilities, damages, judgments, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements (collectively, “Costs”), incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to the fact that

the D&O Indemnified Party is or was a director or officer of Pivot or Merger Partner, whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent permitted under the DGCL for directors or officers of Delaware corporations. Each D&O Indemnified Party will be entitled to advancement of expenses incurred in the defense of any such claim, action, suit, proceeding or investigation from each of Pivot and the Surviving Corporation, jointly and severally, upon receipt by Pivot or the Surviving Corporation from the D&O Indemnified Party of a request therefor; provided that any person to whom expenses are advanced provides an undertaking, to the extent then required by the DGCL or the laws of the state of California, as applicable, to repay such advances if it is ultimately determined that such person is not entitled to indemnification.

(b) The certificate of incorporation and bylaws of each of Pivot and the Surviving Corporation shall contain, and Pivot shall cause the certificate of incorporation and bylaws of the Surviving Corporation to so contain, provisions no less favorable with respect to indemnification, advancement of expenses and exculpation of present and former directors and officers of each of Pivot and Merger Partner than are presently set forth in the certificate of incorporation and bylaws of Pivot and Merger Partner, as applicable, which provisions shall not be amended, modified or repealed for a period of six years time from the Effective Time in a manner that would adversely affect the rights thereunder of individuals who, at or prior to the Effective Time, were officers or directors of Pivot or Merger Partner.

(c) Merger Partner shall purchase an insurance policy, with an effective date as of the Closing, which maintains in effect for six years from the Closing the current directors’ and officers’ liability insurance policies maintained by Merger Partner (provided that Pivot may substitute therefor policies of at least the same coverage containing terms and conditions that are not materially less favorable); provided, however, that in no event shall Pivot be required to expend pursuant to this Section 5.7(c) more than an amount equal to 200% of current annual premiums paid by Merger Partner for such insurance.

(d) Pivot shall maintain directors’ and officers’ liability insurance policies, with an effective date as of the Closing, on commercially available terms and conditions and with coverage limits customary for U.S. public companies similarly situated to Pivot.

(e) Pivot shall pay all expenses, including reasonable attorneys’ fees, that may be incurred by the persons referred to in this Section 5.7 in connection with their enforcement of their rights provided in this Section 5.7.

(f) The provisions of this Section 5.7 are intended to be in addition to the rights otherwise available to the current and former officers and directors of Pivot and Merger Partner by law, charter, statute, bylaw or agreement, and shall operate for the benefit of, and shall be enforceable by, each of the D&O Indemnified Parties, their heirs and their representatives.

(g) In the event Pivot or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers all or substantially all of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of Pivot or the Surviving Corporation, as the case may be, shall succeed to the obligations set forth in this Section 5.7. Pivot shall cause the Surviving Corporation to perform all of the obligations of the Surviving Corporation under this Section 5.7.

5.10 Listing. Pivot shall use its commercially reasonable efforts to maintain its existing listing on the NASDAQ Global Market, to obtain approval of the listing of the combined company on the NASDAQ Global Market and to cause the shares of Pivot Common Stock being issued in the Merger to be approved for listing (subject to notice of issuance) on the NASDAQ Global Market at or prior to the Effective Time.

5.13 Legends.
