     THIS AGREEMENT AND PLAN OF MERGER (this “Agreement”), dated as of May 1, 2008, is by and among Critical Therapeutics, Inc., a Delaware corporation (“Public Company”), Neptune Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of Public Company (the “Transitory Subsidiary”), and Cornerstone BioPharma Holdings, Inc., a Delaware corporation (“Merger Partner”).

     WHEREAS, the Board of Directors of Public Company (the “Public Company Board”) and the Board of Directors of Merger Partner (the “Merger Partner Board”) each deem it advisable and in the best interests of their respective corporation and its stockholders that Public Company and Merger Partner combine in order to advance the long-term business interests of Public Company and Merger Partner;

     WHEREAS, the combination of Public Company and Merger Partner shall be effected through a merger (the “Merger”) of the Transitory Subsidiary into Merger Partner in accordance with the terms of this Agreement and the General Corporation Law of the State of Delaware (the “DGCL”), as a result of which Merger Partner will become a wholly owned subsidiary of Public Company;

     WHEREAS, concurrently with the execution and delivery of this Agreement and as a condition and inducement to Public Company’s willingness to enter into this Agreement, the stockholders of Merger Partner listed on Schedule A-1 to this Agreement have entered into Stockholder Agreements, dated as of the date of this Agreement, in the form attached hereto as Exhibit A-1 (the “Merger Partner Stockholder Agreements”), pursuant to which such stockholders have, among other things, agreed (i) to give Public Company a proxy to vote all of the shares of capital stock of Merger Partner that such stockholders own and (ii) not to transfer or otherwise dispose of any shares of capital stock of Merger Partner that such stockholders own or, for 180 days after the Effective Time, any Public Company Common Stock received in exchange therefor pursuant to the Merger;

     WHEREAS, concurrently with the execution and delivery of this Agreement and as a condition and inducement to Public Company’s willingness to enter into this Agreement, Carolina Pharmaceuticals Ltd., a Bermuda Exempted Company (“Carolina Pharmaceuticals Bermuda”), the holder of that certain Promissory Note, dated April 19, 2004, with Cornerstone BioPharma, Inc., a Nevada corporation and a wholly owned subsidiary of Merger Partner (“Operating Company”), as amended by that certain Promissory Note Amendment and Waiver Agreement, dated June 6, 2006 (as amended, the “Carolina Note”), has entered into a Noteholder Agreement, dated as of the date of this Agreement, in the form attached hereto as Exhibit A-2 (the “Merger Partner Noteholder Agreement”), pursuant to which Carolina Pharmaceuticals Bermuda, among other things, has agreed (i) to exchange or convert the Carolina Note into the common stock, $0.0001 par value per share, of Merger Partner (the “Merger Partner Common Stock”) prior to the Effective Time in accordance with the terms of the Merger Partner Noteholder Agreement, (ii) to give Public Company a proxy to vote all of the shares of capital stock of Merger Partner that Carolina Pharmaceuticals Bermuda owns and (iii) not to transfer or otherwise dispose of any shares of Merger Partner Common Stock that Carolina Pharmaceuticals

Bermuda owns or, for 180 days after the Effective Time, any Public Company Common Stock received in exchange therefor pursuant to the Merger;

     WHEREAS, concurrently with the execution and delivery of this Agreement and as a condition and inducement to Merger Partner’s willingness to enter into this Agreement, the stockholders of Public Company listed on Schedule A-2 to this Agreement have entered into Stockholder Agreements, dated as of the date of this Agreement, in the form attached hereto as Exhibit A-3 (the “Public Company Stockholder Agreements”), pursuant to which such stockholders have, among other things, agreed to give Merger Partner a proxy to vote all of the shares of capital stock of Public Company that such stockholders own;

     WHEREAS, for United States federal income tax purposes, it is intended that the Merger shall qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”);

     NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth below, Public Company, the Transitory Subsidiary and Merger Partner agree as follows:

It is the intention of the parties that the Closing shall occur as soon as practicable after the Public Company Meeting.

     1.3 Effects of the Merger. At the Effective Time, the separate existence of the Transitory Subsidiary shall cease and the Transitory Subsidiary shall be merged with and into Merger Partner (Merger Partner following the Merger is sometimes referred to herein as the “Surviving Corporation”), and the Merger shall have the effects set forth in the DGCL.

     1.4 Certificate of Incorporation; Bylaws.

          (a) The Certificate of Incorporation of the Surviving Corporation shall be amended at the Effective Time in its entirety to read in the form attached hereto as Exhibit B.

          (b) The Bylaws of the Surviving Corporation immediately following the Effective Time shall be the same as the Bylaws of the Transitory Subsidiary immediately prior to the Effective Time, except that the name of the corporation set forth therein shall be changed to “Cornerstone BioPharma Holdings, Inc.”

     1.5 Directors and Officers of the Surviving Corporation.

          (a) The directors of Merger Partner immediately prior to the Effective Time shall be the initial directors of the Surviving Corporation, each to hold office in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation.

ARTICLE II

CONVERSION OF SECURITIES

     2.1 Reverse Split of Public Company Common Stock.

          (a) Immediately prior to the Effective Time, and subject to receipt of the Public Company Stockholder Approval, Public Company shall cause to be filed a Certificate of Amendment to its Certificate of Incorporation (the “Public Company Charter Amendment”), whereby, upon the effectiveness of filing of the Public Company Charter Amendment, without any further action on the part of Public Company, Merger Partner or any stockholder of Public Company:

               (i) Each share of common stock, $0.001 par value per share, of Public Company (“Public Company Common Stock”) issued and outstanding immediately prior to the effective time specified in the Public Company Charter Amendment shall be reclassified and combined into and become a fractional number of fully paid and nonassessable shares of Public Company Common Stock to be mutually agreed upon by Public Company and Merger Partner (the “Reverse Stock Split”).

               (ii) Any shares of Public Company Common Stock held as treasury stock or owned by Public Company immediately prior to the filing of the Public Company Charter Amendment shall each be reclassified and combined into and become an identical

fractional number of shares of Public Company Common Stock as determined by the Board of Directors of Public Company in connection with Section 2.1(a)(i).

          (b) No certificates or scrip representing fractional shares of Public Company Common Stock shall be issued in connection with the Reverse Stock Split. Each holder of shares of Public Company Common Stock who would otherwise have been entitled to receive a fraction of a share of Public Company Common Stock (after taking into account all fractional shares of Public Company Common Stock otherwise issuable to such holder) shall be entitled to receive, in lieu thereof, upon surrender of such holder’s certificate(s) representing such fractional shares of Public Company Common Stock, cash (without interest) in an amount equal to such fractional part of a share of Public Company Common Stock multiplied by the average last reported sales prices of Public Company Common Stock at the 4:00 p.m., Eastern time, end of regular trading hours on The NASDAQ Stock Market LLC (“NASDAQ”) during the ten consecutive trading days ending on the last trading day prior to the Effective Time.

          (c) To give effect to, and as of the effective time of, the Reverse Stock Split, Public Company shall adjust and proportionately decrease the number of shares of Public Company Common Stock reserved for issuance upon exercise of, and adjust and proportionately increase the exercise price of, all options, warrants and other rights to acquire Public Company Common Stock.

          (d) The Exchange Ratio shall be appropriately adjusted at the Effective Time to reflect fully the effect of the Reverse Stock Split.

          2.2 Conversion of Capital Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of the capital stock of Merger Partner or the holder of any shares of the capital stock of the Transitory Subsidiary:

          (a) Capital Stock of the Transitory Subsidiary. Each share of the common stock of the Transitory Subsidiary issued and outstanding immediately prior to the Effective Time shall be converted into and become one fully paid and nonassessable share of common stock, $0.001 par value per share, of the Surviving Corporation.

          (b) Cancellation of Treasury Stock and Public Company Owned Stock. All shares of Merger Partner Common Stock that are owned by Merger Partner as treasury stock or by any wholly owned Subsidiary of Merger Partner and any shares of Merger Partner Common Stock owned by Public Company, the Transitory Subsidiary or any other wholly owned Subsidiary of Public Company immediately prior to the Effective Time shall be cancelled and shall cease to exist and no stock of Public Company or other consideration shall be delivered in exchange therefor.

          (c) Exchange Ratio for Merger Partner Common Stock. Upon surrender of the certificate representing such share of Merger Partner Common Stock in the manner provided in Section 2.3 and subject to the provisions thereof, each share of Merger Partner Common Stock (other than shares to be cancelled in accordance with Section 2.2(b) and Dissenting Shares) shall be converted into and exchanged for the right to receive a number of shares of Public Company Common Stock equal to the product of (i) 2.3333 multiplied by (ii) the quotient of (A)

43,479,198 divided by (B) the sum of (x) the number of shares of Merger Partner Common Stock outstanding immediately prior to the Effective Time plus (y) the number of shares of Merger Partner Common Stock issuable upon exercise of Merger Partner Stock Options and Merger Partner Warrants outstanding immediately prior to the Effective Time, subject to adjustment as provided in Section 2.1(d) (the “Exchange Ratio”). As of the Effective Time, all such shares of Merger Partner Common Stock shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of a certificate representing any such shares of Merger Partner Common Stock shall cease to have any rights with respect thereto, except the right to receive the shares of Public Company Common Stock pursuant to this Section 2.2(c) and any cash in lieu of fractional shares of Public Company Common Stock to be issued or paid in consideration therefor upon the surrender of such certificate in accordance with Section 2.3, without interest. For purposes of this Agreement, “Dissenting Shares” shall mean Merger Partner Common Stock held as of the Effective Time that has not been voted in favor of the adoption of this Agreement and with respect to which appraisal shall have been duly demanded and perfected in accordance with the DGCL and not effectively withdrawn or forfeited prior to the Effective Time.

          (d) Unvested Stock. At the Effective Time, any shares of Public Company Common Stock issued in accordance with Section 2.2(c) with respect to any unvested shares of Merger Partner Common Stock awarded to employees, directors or consultants pursuant to any of Merger Partner’s plans or arrangements and outstanding immediately prior to the Effective Time shall remain subject to the same terms, restrictions and vesting schedule as in effect immediately prior to the Effective Time, except to the extent by their terms such unvested shares of Merger Partner Common Stock vest at the Effective Time. Copies of the relevant agreements governing such shares and the vesting thereof have been provided or made available to Public Company. All outstanding rights that Merger Partner may hold immediately prior to the Effective Time to repurchase unvested shares of Merger Partner Common Stock shall be assigned to Public Company in the Merger and shall thereafter be exercisable by Public Company upon the same terms and conditions in effect immediately prior to the Effective Time, except that the shares purchasable pursuant to such rights and the purchase price payable per share shall be appropriately adjusted to reflect the Exchange Ratio. Merger Partner shall take all steps necessary to cause the foregoing provisions of this Section 2.2(d) to occur.

     2.3 Exchange of Certificates. The procedures for exchanging outstanding shares of Merger Partner Common Stock for Public Company Common Stock pursuant to the Merger are as follows:

          (a) Exchange Agent. As of the Effective Time, Public Company shall deposit with BNY Mellon Shareowner Services or another bank or trust company designated by Public Company and reasonably acceptable to Merger Partner (the “Exchange Agent”), for the benefit of the holders of shares of Merger Partner Common Stock, for exchange in accordance with this Section 2.3, through the Exchange Agent, (i) certificates representing the shares of Public Company Common Stock (such shares of Public Company Common Stock, together with any dividends or distributions with respect thereto with a record date after the Effective Time, being hereinafter referred to as the “Exchange Fund”) issuable pursuant to Section 2.2 in exchange for outstanding shares of Merger Partner Common Stock, (ii) cash in an amount sufficient to make payments for fractional shares required pursuant to Section 2.3(c) and (iii) any dividends or

distributions to which holders of certificates that immediately prior to the Effective Time represented outstanding shares of Merger Partner Common Stock (the “Certificates”) whose shares were converted pursuant to Section 2.2 into the right to receive shares of Public Company Common Stock may be entitled pursuant to Section 2.3(d).

          (b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each holder of record of a Certificate (i) a letter of transmittal in customary form (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent) and (ii) instructions for effecting the surrender of the Certificates in exchange for certificates representing shares of Public Company Common Stock (plus cash in lieu of fractional shares, if any, of Public Company Common Stock and any dividends or distributions as provided below). Upon surrender of a Certificate for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Public Company, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate shall be entitled to receive in exchange therefor a certificate representing that number of whole shares of Public Company Common Stock which such holder has the right to receive pursuant to the provisions of this Article II plus cash in lieu of fractional shares pursuant to Section 2.3(c) and any dividends or distributions then payable pursuant to Section 2.3(d), and the Certificate so surrendered shall immediately be cancelled. In the event of a transfer of ownership of Merger Partner Common Stock which is not registered in the transfer records of Merger Partner, a certificate representing the proper number of shares of Public Company Common Stock plus cash in lieu of fractional shares pursuant to Section 2.3(c) and any dividends or distributions pursuant to Section 2.3(d) may be issued or paid to a person other than the person in whose name the Certificate so surrendered is registered, if such Certificate is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 2.3, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the certificate representing shares of Public Company Common Stock plus cash in lieu of fractional shares pursuant to Section 2.3(c) and any dividends or distributions then payable pursuant to Section 2.3(d), as contemplated by this Section 2.3.

          (c) No Fractional Shares. No certificate or scrip representing fractional shares of Public Company Common Stock shall be issued upon the surrender for exchange of Certificates, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of Public Company. Notwithstanding any other provision of this Agreement, each holder of shares of Merger Partner Common Stock converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Public Company Common Stock (after taking into account all Certificates delivered by such holder and the aggregate number of shares of Merger Partner Common Stock represented thereby) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of Public Company Common Stock multiplied by the average of the last reported sales prices of Public Company Common Stock at the 4:00 p.m., Eastern time, end of regular trading hours on NASDAQ during the ten consecutive trading days ending on the last trading day prior to the Effective Time.

          (d) Distributions with Respect to Unexchanged Shares. No dividends or other distributions declared or made after the Effective Time with respect to Public Company Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate until such Certificate is surrendered as described in Section 2.3(b), subject to Section 2.3(i). Subject to the effect of applicable laws, following surrender of any such Certificate, there shall be issued and paid to the record holder of the Certificate, at the time of such surrender the amount of dividends or other distributions with a record date after the Effective Time previously paid with respect to such whole shares of Public Company Common Stock, without interest, and at the appropriate payment date, the amount of dividends or other distributions having a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender that are payable with respect to such whole shares of Public Company Common Stock.

          (e) No Further Ownership Rights in Merger Partner Common Stock. All shares of Public Company Common Stock issued upon the surrender for exchange of Certificates in accordance with the terms hereof (including any cash or dividends or other distributions paid pursuant to Section 2.3(c) or 2.3(d)) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to such shares of Merger Partner Common Stock, and from and after the Effective Time there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Merger Partner Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Article II, subject to applicable law in the case of Dissenting Shares.

          (f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Merger Partner Common Stock for 180 days after the Effective Time shall be delivered to Public Company, upon demand, and any holder of Merger Partner Common Stock who has not previously complied with this Section 2.3 shall thereafter look only to Public Company, as a general unsecured creditor, for payment of its claim for Public Company Common Stock, any cash in lieu of fractional shares of Public Company Common Stock and any dividends or distributions with respect to Public Company Common Stock.

          (g) No Liability. To the extent permitted by applicable law, none of Public Company, the Transitory Subsidiary, Merger Partner, the Surviving Corporation or the Exchange Agent shall be liable to any holder of shares of Merger Partner Common Stock or Public Company Common Stock, as the case may be, for such shares (or dividends or distributions with respect thereto) delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate shall not have been surrendered immediately prior to such date on which any shares of Public Company Common Stock, and any cash payable to the holder of such Certificate or any dividends or distributions payable to the holder of such Certificate pursuant to this Article II would otherwise escheat to or become the property of any Governmental Entity, any such shares of Public Company Common Stock or cash, dividends or distributions in respect of such Certificate shall, to the extent permitted by applicable law, become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto.

          (h) Withholding Rights. Each of Public Company, the Surviving Corporation and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Merger Partner Common Stock and any other recipient of payments hereunder such amounts as it reasonably determines that it is required to deduct and withhold with respect to the making of such payment under the Code, or any other applicable provision of law. To the extent that amounts are so withheld by the Surviving Corporation, Public Company or the Exchange Agent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Merger Partner Common Stock or other recipient of payments hereunder in respect of which such deduction and withholding was made by the Surviving Corporation, Public Company or the Exchange Agent, as the case may be.

          (i) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such person of a bond in such reasonable amount as the Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificate the shares of Public Company Common Stock and any cash in lieu of fractional shares, and unpaid dividends and distributions on shares of Public Company Common Stock deliverable in respect thereof pursuant to this Agreement.

     2.4 Merger Partner Stock Plans and Merger Partner Warrants.

          (a) At the Effective Time, each outstanding option to purchase Merger Partner Common Stock (“Merger Partner Stock Options”), whether vested or unvested, and all stock option plans or other stock or equity-related plans of Merger Partner (the “Merger Partner Stock Plans”) themselves, insofar as they relate to outstanding Merger Partner Stock Options, shall be assumed by Public Company and shall become an option to acquire, on the same terms and conditions as were applicable under such Merger Partner Stock Option immediately prior to the Effective Time, such number of shares of Public Company Common Stock as is equal to the number of shares of Merger Partner Common Stock subject to the unexercised portion of such Merger Partner Stock Option immediately prior to the Effective Time multiplied by the Exchange Ratio (rounded down to the nearest whole share number), at an exercise price per share equal to the exercise price per share of such Merger Partner Stock Option immediately prior to the Effective Time divided by the Exchange Ratio (rounded up to the nearest whole cent); provided that the assumption of each Merger Partner Stock Option pursuant to this Section 2.4(a) shall comply with all requirements of Sections 424 and 409A of the Code and the final Treasury regulations issued thereunder. Such Merger Partner Stock Options shall continue in effect on the same terms and conditions to which they are currently subject (subject to the adjustments required by this Section 2.4 after giving effect to the Merger).

          (b) As soon as practicable after the Effective Time, Public Company shall deliver to the participants in the Merger Partner Stock Plans appropriate notice setting forth such participants’ rights pursuant to the Merger Partner Stock Options, as provided in this Section 2.4.

          (c) Public Company shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Public Company Common Stock for delivery upon exercise of the Merger Partner Stock Options assumed in accordance with this Section 2.4. As promptly as practicable after the Effective Time, Public Company shall file a registration statement on Form S-8 (or any successor form) or another appropriate form with respect to the shares of Public Company Common Stock subject to such options and shall use commercially reasonable efforts to maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such options remain outstanding.

          (d) Merger Partner shall terminate any employee stock purchase plans in accordance with their terms as of or prior to the Effective Time.

          (e) At the Effective Time, each Merger Partner Warrant outstanding immediately prior to the Effective Time shall be assumed by Public Company and shall become a warrant to acquire, on the same terms and conditions as were applicable under such Merger Partner Warrant, such number of shares of Public Company Common Stock as is equal to the number of shares of Merger Partner Common Stock subject to the unexercised portion of such Merger Partner Warrant immediately prior to the Effective Time multiplied by the Exchange Ratio (rounded down to the nearest whole share number), at an exercise price per share equal to the exercise price per share of such Merger Partner Warrant immediately prior to the Effective Time divided by the Exchange Ratio (rounded up to the nearest whole cent) (each, as so adjusted, an “Adjusted Warrant”). Prior to the Effective Time, Public Company shall take all necessary actions for the assumption of Merger Partner Warrants and their conversion into Adjusted Warrants, including the reservation and listing of Public Company Common Stock in a number at least equal to the number of shares of Public Company Common Stock that will be subject to the Adjusted Warrants.

     2.5 Dissenting Shares.

          (a) Dissenting Shares shall not be converted into or represent the right to receive Public Company Common Stock unless the stockholder holding such Dissenting Shares shall have forfeited his, her or its right to appraisal under the DGCL or properly withdrawn his, her or its demand for appraisal. If such stockholder has so forfeited or withdrawn his, her or its right to appraisal of Dissenting Shares, then (i) as of the occurrence of such event, such holder’s Dissenting Shares shall cease to be Dissenting Shares and shall be converted into and represent the right to receive the Public Company Common Stock issuable in respect of such Merger Partner Common Stock pursuant to Section 2.2(c), and (ii) promptly following the occurrence of such event, Public Company shall deliver to the Exchange Agent a certificate representing the Public Company Common Stock to which such stockholder is entitled pursuant to Section 2.2(c).

          (b) Merger Partner shall give Public Company (i) prompt notice of any written demands for appraisal of any Merger Partner Common Stock, withdrawals of such demands and any other instruments that relate to such demands received by Merger Partner and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the DGCL. Merger Partner shall not, except with the prior written consent of

Public Company, make any payment with respect to any demands for appraisal of Merger Partner Common Stock or offer to settle or settle any such demands.

     Merger Partner represents and warrants to Public Company and the Transitory Subsidiary that the statements contained in this Article III are true and correct, except as expressly set forth herein or in the disclosure schedule delivered by Merger Partner to Public Company and the Transitory Subsidiary on the date of this Agreement (the “Merger Partner Disclosure Schedule”). The Merger Partner Disclosure Schedule shall be arranged in sections corresponding to the numbered and lettered sections contained in this Article III and the disclosure in any section shall qualify (1) the corresponding section in this Article III and (2) the other sections in this Article III only to the extent that it is reasonably apparent from a reading of such disclosure that it also qualifies or applies to such other sections. For purposes hereof, “to the knowledge of Merger Partner” and similar expressions mean the knowledge of the persons identified on the Merger Partner Disclosure Schedule for this purpose, as well as any other knowledge which such persons would have possessed had they made reasonable inquiry with respect to the matter in question.

     3.1 Organization, Standing and Power. Merger Partner is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation, has all requisite corporate power and authority to own, lease and operate its properties and assets and to carry on its business as currently conducted and as currently proposed to be conducted, and is duly qualified to do business and is in good standing as a foreign corporation in each jurisdiction listed on Section 3.1 of the Merger Partner Disclosure Schedule, which jurisdictions constitute the only jurisdictions in which the character of the properties it owns, operates or leases or the nature of its activities makes such qualification necessary, except for such failures to be so organized, qualified or in good standing, individually or in the aggregate, that have not had, and are not reasonably likely to have, a Merger Partner Material Adverse Effect. For purposes of this Agreement, the term “Merger Partner Material Adverse Effect” means any material adverse change, event, circumstance or development with respect to, or material adverse effect on, (i) the business, assets, liabilities, condition (financial or other), or results of operations of Merger Partner and its Subsidiaries, taken as a whole, or (ii) the ability of Merger Partner and its Subsidiaries to consummate the transactions contemplated by this Agreement; provided, however, that the following shall not be deemed to be a Merger Partner Material Adverse Effect: any change or event caused by or resulting from (A) changes in prevailing economic or market conditions in the United States or any other jurisdiction in which such entity has substantial business operations (except to the extent those changes have a materially disproportionate effect on Merger Partner and its Subsidiaries as compared to other similarly situated participants in the industries or markets in which Merger Partner and its Subsidiaries operate), (B) changes or events, after the date hereof, affecting the industries in which they operate generally (except to the extent those changes or events have a materially disproportionate effect on Merger Partner and its Subsidiaries as compared to other similarly situated participants in the industries or markets in which Merger Partner and its Subsidiaries operate), (C) changes, after the date hereof, in generally accepted accounting principles or requirements applicable to Merger Partner and its Subsidiaries (except to the extent those

changes have a materially disproportionate effect on Merger Partner and its Subsidiaries as compared to other similarly situated participants in the industries or markets in which Merger Partner and its Subsidiaries operate), (D) changes, after the date hereof, in laws, rules or regulations of general applicability or interpretations thereof by any Governmental Entity (except to the extent those changes have a materially disproportionate effect on Merger Partner and its Subsidiaries as compared to other similarly situated participants in the industries or markets in which Merger Partner and its Subsidiaries operate), (E) the execution, delivery and performance of this Agreement or the consummation of the transactions contemplated hereby or thereby or the announcement thereof, or (F) any outbreak of major hostilities in which the United States is involved or any act of terrorism within the United States or directed against its facilities or citizens wherever located. For the avoidance of doubt, the parties agree that the terms “material,” “materially” and “materiality” as used in this Agreement with an initial lower case “m” shall have their respective customary and ordinary meanings, without regard to the meanings ascribed to Merger Partner Material Adverse Effect in the prior sentence of this paragraph or Public Company Material Adverse Effect in Section 4.1. Merger Partner has provided or made available to Public Company complete and accurate copies of its Certificate of Incorporation and Bylaws and is not in default under or in violation of any provision of either such document.

          (a) Merger Partner has all requisite corporate power and authority to enter into this Agreement, subject only to the adoption of this Agreement (the “Merger Partner Voting Proposal”) by Merger Partner’s stockholders under the DGCL (the “Merger Partner Stockholder Approval”), to consummate the transactions contemplated by this Agreement. Without limiting the generality of the foregoing, the Merger Partner Board, at a meeting duly called and held, by the unanimous vote of all directors, or by unanimous written consent in lieu of a meeting, (i) determined that the Merger is advisable, fair and in the best interests of Merger Partner and its stockholders, (ii) approved this Agreement and declared its advisability in accordance with the provisions of the DGCL, (iii) directed that this Agreement be submitted to the stockholders of Merger Partner for their adoption and resolved to recommend that the stockholders of Merger Partner vote in favor of the adoption of this Agreement and (iv) to the extent necessary, adopted a resolution having the effect of causing Merger Partner not to be subject to any state takeover law or similar law that might otherwise apply to the Merger and any other transactions contemplated by this Agreement.

Section 3.4(b) of the Merger Partner Disclosure Schedule lists all consents, waivers and approvals under any of Merger Partner’s or any of its Subsidiaries’ agreements, licenses or leases required to be obtained in connection with the consummation of the transactions contemplated by this Agreement, which, if individually or in the aggregate were not obtained, would result in a material loss of benefits to Merger Partner, Public Company or the Surviving Corporation as a result of the Merger.

          (c) No consent, approval, license, permit, order or authorization of, or registration, declaration, notice or filing with, any court, arbitrational tribunal, administrative agency or commission or other governmental or regulatory authority, agency or instrumentality (a “Governmental Entity”) is required by or with respect to Merger Partner or any of its Subsidiaries in connection with the execution and delivery of this Agreement by Merger Partner or the consummation by Merger Partner of the transactions contemplated by this Agreement, except for (i) the filing of the Certificate of Merger with the Delaware Secretary of State and appropriate corresponding documents with the appropriate authorities of other states in which Merger Partner is qualified as a foreign corporation to transact business, (ii) the filing of the Proxy Statement/Prospectus with the U.S. Securities and Exchange Commission (the “SEC”) in accordance with the Securities Exchange Act of 1934, as amended (the “Exchange Act”), (iii) such consents, approvals, orders, authorizations, registrations, declarations and filings as may be required under applicable state securities laws and (iv) such other consents, authorizations, orders, filings, approvals and registrations that, individually or in the aggregate, if not obtained or made, would not be reasonably likely to have a Merger Partner Material Adverse Effect.

          (d) The affirmative vote in favor of the Merger Partner Voting Proposal by the holders of a majority of the votes represented by the outstanding shares of Merger Partner Common Stock, which is to be delivered pursuant to written consents of stockholders in lieu of a

meeting (collectively, the “Written Consents”), is the only vote of the holders of any class or series of Merger Partner’s capital stock or other securities necessary to adopt this Agreement and for consummation by Merger Partner of the other transactions contemplated by this Agreement. There are no bonds, debentures, notes or other indebtedness of Merger Partner having the right to vote (or convertible into, or exchangeable for, securities having the right to vote) on any matters on which stockholders of Merger Partner may vote.

          (b) The execution and delivery of this Agreement and consummation of the Merger will not result in the breach of, or create on behalf of any third party the right to terminate or modify, (i) any license, sublicense or other agreement relating to any Intellectual Property owned by Merger Partner or any of its Subsidiaries that is material to the business of Merger Partner and its Subsidiaries, taken as a whole, including software that is used in the development or manufacture of or forms a part of any product or service sold by or expected to be sold by Merger Partner or any of its Subsidiaries (the “Merger Partner Intellectual Property”) or (ii) any license, sublicense and other agreement as to which Merger Partner or any of its Subsidiaries is a party and pursuant to which Merger Partner or any of its Subsidiaries is authorized to use any third party Intellectual Property that is material to the business of Merger Partner and its Subsidiaries, taken as a whole, including software that is used in the development or manufacture of or forms a part of any product or service sold by or expected to be sold by

No Merger Partner Employee Plan that is a “nonqualified deferred compensation plan” has been materially modified (as determined under Notice 2005-1) after October 3, 2004. No event has occurred that would be treated by Code Section 409A(b) as a transfer of property for purposes of Code Section 83.

REPRESENTATIONS AND WARRANTIES OF PUBLIC COMPANY AND THE

     Public Company and the Transitory Subsidiary represent and warrant to Merger Partner that the statements contained in this Article IV are true and correct, except as expressly set forth herein or in the disclosure schedule delivered by Public Company and the Transitory Subsidiary to Merger Partner on the date of this Agreement (the “Public Company Disclosure Schedule”). The Public Company Disclosure Schedule shall be arranged in sections corresponding to the numbered and lettered sections contained in this Article IV and the disclosure in any section shall qualify (1) the corresponding section in this Article IV and (2) the other sections in this Article IV only to the extent that it is reasonably apparent from a reading of such disclosure that it also qualifies or applies to such other sections. For purposes hereof, “to the knowledge of Public Company” and similar expressions mean the knowledge of the persons identified on the Public Company Disclosure Schedule for this purpose, as well as any other knowledge which such persons would have possessed had they made reasonable inquiry with respect to the matter in question.

     4.1 Organization, Standing and Power. Each of Public Company and the Transitory Subsidiary is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation, has all requisite corporate power and authority to own, lease and operate its properties and assets and to carry on its business as currently conducted and as currently proposed to be conducted, and is duly qualified to do business and is in good standing as a foreign corporation in each jurisdiction listed on Section 4.1(i) of the Public Company Disclosure Schedule, which jurisdictions constitute the only jurisdictions in which the character of the properties it owns, operates or leases or the nature of its activities makes such qualification necessary, except for such failures to be so organized, qualified or in good standing, individually or in the aggregate, that have not had, and are not reasonably likely to have, a Public Company Material Adverse Effect. For purposes of this Agreement, the term “Public Company Material Adverse Effect” means any material adverse change, event, circumstance or development with respect to, or material adverse effect on, (i) the business, assets, liabilities, condition (financial or other), or results of operations of Public Company and its Subsidiaries, taken as a whole, or (ii) the ability of Public Company and its Subsidiaries to consummate the transactions contemplated by this Agreement; provided, however, that the following shall not be deemed to be a Public Company Material Adverse Effect: any change or event caused by or resulting from (A) changes in prevailing economic or market conditions in the United States or any other jurisdiction in which Public Company has substantial business operations (except to the extent those changes have a materially disproportionate effect on Public Company and its Subsidiaries as compared to other similarly situated participants in the industries or markets in which Public Company and its Subsidiaries operate), (B) changes or events, after the date hereof, affecting the industries in which they operate generally (except to the extent those changes or events have a materially disproportionate effect on Public Company and its Subsidiaries as compared to other similarly situated participants in the industries or markets in which Public Company and its Subsidiaries operate), (C) changes, after the date hereof, in generally accepted accounting principles or requirements applicable to Public Company and its Subsidiaries (except to the extent those changes have a materially disproportionate effect on Merger Partner and its

Subsidiaries as compared to other similarly situated participants in the industries or markets in which Public Company and its Subsidiaries operate), (D) changes, after the date hereof, in laws, rules or regulations of general applicability or interpretations thereof by any Governmental Entity (except to the extent those changes have a materially disproportionate effect on Public Company and its Subsidiaries as compared to other similarly situated participants in the industries or markets in which Public Company and its Subsidiaries operate), (E) the execution, delivery and performance of this Agreement or the consummation of the transactions contemplated hereby or thereby or the announcement thereof, (F) any outbreak of major hostilities in which the United States is involved or any act of terrorism within the United States or directed against its facilities or citizens wherever located, or (G) the matters described on Section 4.1(ii) of the Public Company Disclosure Schedule; and provided, further, that in no event shall a change in the public trading price of Public Company Common Stock, by itself, be considered material or constitute a Public Company Material Adverse Effect, although the underlying cause of any change in the public trading price of Public Company Common Stock may nonetheless be considered in determining the occurrence of a Public Company Material Adverse Effect. For the avoidance of doubt, the parties agree that the terms “material,” “materially” and “materiality” as used in this Agreement with an initial lower case “m” shall have their respective customary and ordinary meanings, without regard to the meanings ascribed to Public Company Material Adverse Effect in the prior sentence of this paragraph or Merger Partner Material Adverse Effect in Section 3.1. Public Company has provided or made available to Merger Partner complete and accurate copies of its Certificate of Incorporation and Bylaws.

Neither Public Company, nor any of its Subsidiaries nor, to the knowledge of Public Company, any other party is in default under any of the Public Company Leases, except where the existence of such defaults, individually or in the aggregate, has not had, and is not reasonably

likely to have, a Public Company Material Adverse Effect. Neither Public Company nor any of its Subsidiaries leases, subleases or licenses any real property to any person other than Public Company and its Subsidiaries. Public Company has provided or made available to Merger Partner complete and accurate copies of all Public Company Leases.

     4.10 Intellectual Property.

          (b) The execution and delivery of this Agreement and consummation of the Merger will not result in the breach of, or create on behalf of any third party the right to terminate or modify, (i) any license, sublicense or other agreement relating to any Intellectual Property owned by Public Company or any of its Subsidiaries that is material to the business of Public Company and its Subsidiaries, taken as a whole, including software that is used in the development or manufacture of or forms a part of any product or service sold by or expected to be sold by Public Company or any of its Subsidiaries (the “Public Company Intellectual Property”) or (ii) any license, sublicense and other agreement as to which Public Company or any of its Subsidiaries is a party and pursuant to which Public Company or any of its Subsidiaries is authorized to use any third party Intellectual Property that is material to the business of Public Company and its Subsidiaries, taken as a whole, including software that is used in the development or manufacture of or forms a part of any product or service sold by or expected to be sold by Public Company or any of its Subsidiaries (the “Public Company Third Party Intellectual Property”). Section 4.10(b)(i) of the Public Company Disclosure Schedule sets forth a complete and accurate list of Public Company Intellectual Property (other than unregistered copyrights, trade secrets and confidential information) and Section 4.10(b)(ii) sets forth a complete and accurate list of all Public Company Third Party Intellectual Property.

          (c) All patents and registrations and applications for Trademarks, service marks and copyrights which are held by Public Company or any of its Subsidiaries and that are material to the business of Public Company and its Subsidiaries, taken as a whole, are valid and subsisting.

To the knowledge of Public Company, no other person or entity is infringing, violating or misappropriating any of the Public Company Intellectual Property or Public Company Third Party Intellectual Property, except for infringements, violations or misappropriations that, individually or in the aggregate, are not reasonably likely to have a Public Company Material Adverse Effect.

          (d) To the knowledge of Public Company, none of the (i) products previously or currently sold by Public Company or any of its Subsidiaries or (ii) business or activities previously or currently conducted by Public Company or any of its Subsidiaries infringes,

          (c) There is no non-competition or other similar agreement, commitment, judgment, injunction or order to which Public Company or any of its Subsidiaries is a party or is subject that has or could reasonably be expected to have the effect of prohibiting or impairing in any material respect the conduct of the business of Public Company or any of its Subsidiaries or Merger Partner or any of its Subsidiaries as currently conducted and as currently proposed to be conducted in any material respect. Neither Public Company nor any of its Subsidiaries has entered into (or is otherwise bound by) any agreement under which it is restricted in any material respect from selling, licensing or otherwise distributing any of its technology or products, or providing services to, customers or potential customers or any class of customers, in any geographic area, during any period of time or any segment of the market or line of business.

          (d) Except as identified on the exhibit index of any Public Company Recent SEC Document, neither Public Company nor any of its Subsidiaries is a party to any agreement under which is licensed any material Intellectual Property to or from any third party (excluding currently-available, off-the-shelf software programs that are licensed by Public Company or any of its Subsidiaries pursuant to “shrink wrap” licenses under which aggregate fees and royalties paid to the licensor do not exceed $50,000 annually).

Neither Public Company nor any of its Subsidiaries has received any notice in writing from any other party, and, to the knowledge of Public Company, no party has threatened, to terminate, cancel, fail to renew or otherwise materially modify any such agreements the loss of which, individually or in the aggregate, is reasonably likely to have a Public Company Material Adverse Effect.

Except as disclosed in the Public Company Recent SEC Documents, there is no action, suit, proceeding, claim, arbitration or investigation before any Governmental Entity or before any arbitrator that is pending or, to the knowledge of Public Company, has been threatened in writing against Public Company or any of its Subsidiaries that (a) seeks either damages in excess of $150,000 or equitable relief or (b) in any manner challenges or seeks to prevent, enjoin, alter or delay the transactions contemplated by this Agreement.

          (c) Each Public Company Employee Plan has been administered in all material respects in accordance with ERISA, the Code and all other applicable laws and the regulations thereunder and in accordance with its terms and each of Public Company and its Subsidiaries and their respective ERISA Affiliates has in all material respects met its obligations with respect to such Public Company Employee Plan and has made all required contributions thereto (or reserved such contributions on the Public Company Balance Sheet). Public Company and its Subsidiaries and each of their respective ERISA Affiliates and each Public Company Employee Plan are in compliance in all material respects with the currently applicable provisions of ERISA and the Code and the regulations thereunder (including Section 4980B of the Code, Subtitle K, Chapter 100 of the Code and Sections 601 through 608 and Section 701 et seq. of ERISA). All filings and reports as to each Public Company Employee Plan required to have been submitted to the IRS or to the United States Department of Labor have been timely submitted. With respect to Public Company Employee Plans, no event has occurred, and to the knowledge of Public Company, there exists no condition or set of circumstances in connection with which Public Company or any of its Subsidiaries could be subject to any liability that is reasonably likely, individually or in the aggregate, to have a Public Company Material Adverse Effect under ERISA, the Code or any other applicable law.

          (d) With respect to Public Company Employee Plans, there are no benefit obligations for which contributions have not been made or properly accrued and there are no benefit obligations that have not been accounted for by reserves, or otherwise properly footnoted in accordance with GAAP, on the financial statements of Public Company, which obligations are reasonably likely, individually or in the aggregate, to have a Public Company Material Adverse Effect. The assets of each Public Company Employee Plan that is funded are reported at their fair market value on the books and records of such Public Company Employee Plan.

          (e) All Public Company Employee Plans that are intended to be qualified under Section 401(a) of the Code have received determination letters from the IRS to the effect that such Public Company Employee Plans are qualified and the plans and trusts related thereto are exempt from federal income taxes under Sections 401(a) and 501(a), respectively, of the Code, no such determination letter has been revoked and revocation has not been threatened, and no such Employee Benefit Plan has been amended or operated since the date of its most recent determination letter or application therefor in any respect, and no act or omission has occurred, that would adversely affect its qualification or materially increase its cost. Each Public Company Employee Plan that is required to satisfy Section 401(k)(3) or Section 401(m)(2) of the Code has been tested for compliance with, and satisfies the requirements of, Section 401(k)(3) and Section 401(m)(2) of the Code, as the case may be, for each plan year ending prior to the Closing Date.

          (f) Neither Public Company nor any of its Subsidiaries nor any of their respective ERISA Affiliates has (i) ever maintained a Public Company Employee Benefit Plan that was ever subject to Section 412 of the Code or Title IV of ERISA or (ii) ever been obligated to contribute to a “multiemployer plan” (as defined in Section 4001(a)(3) of ERISA). No Public Company Employee Plan is funded by, associated with or related to a “voluntary employees’ beneficiary association” within the meaning of Section 501(c)(9) of the Code.

The investment vehicles used to fund Public Company Employee Plans may be changed at any time without incurring a material sales charge, surrender fee or other similar expense.

          (h) Except as identified on the exhibit index of any Public Company Recent SEC Document, neither Public Company nor any of its Subsidiaries is a party to any oral or written (i) agreement with any stockholders, director, executive officer or other employee of Public Company or any of its Subsidiaries (A) the benefits of which are contingent, or the terms of which are materially altered, upon the occurrence of a transaction involving Public Company or any of its Subsidiaries of the nature of any of the transactions contemplated by this Agreement, (B) providing any term of employment or compensation guarantee or (C) providing severance benefits or other benefits after the termination of employment of such director, executive officer or employee; (ii) agreement, plan or arrangement under which any person may receive payments from Public Company or any of its Subsidiaries that may be subject to the tax imposed by Section 4999 of the Code or included in the determination of such person’s “parachute payment” under Section 280G of the Code, without regard to Section 280G(b)(4); or (iii) agreement or plan binding Public Company or any of its Subsidiaries, including any stock option plan, stock appreciation right plan, restricted stock plan, stock purchase plan or severance benefit plan, any of the benefits of which shall be increased, or the vesting of the benefits of which shall be accelerated, by the occurrence of any of the transactions contemplated by this Agreement or the value of any of the benefits of which shall be calculated on the basis of any of the transactions contemplated by this Agreement.

          (i) None of the Public Company Employee Plans promises or provides retiree medical or other retiree welfare benefits to any person, except as required by applicable law.

          (j) Each Public Company Employee Plan that is a “nonqualified deferred compensation plan” (as defined in Code Section 409A(d)(1)) has been operated since January 1, 2005 in good faith reasonable compliance with Code Section 409A and IRS Notice 2005-1. No Public Company Employee Plan that is a “nonqualified deferred compensation plan” has been materially modified (as determined under Notice 2005-1) after October 3, 2004. No event has occurred that would be treated by Code Section 409A(b) as a transfer of property for purposes of Code Section 83. Since Public Company became subject to the reporting requirements of Section 13 or Section 15(d) of the Exchange Act, no stock option or equity unit option granted under any Public Company Employee Plan has an exercise price that has been or may be less than the fair market value of the underlying stock or equity units (as the case may be) as of the date such option was granted or has any feature for the deferral of compensation other than the deferral of recognition of income until the later of exercise or disposition of such option.

     4.15 Compliance With Laws. Public Company and each of its Subsidiaries has complied with, is not in violation of, and has not received any notice alleging any violation with respect to, any applicable provisions of any statute, law or regulation with respect to the conduct of its business, or the ownership or operation of its properties or assets, except for failures to comply or violations that, individually or in the aggregate, have not had, and are not reasonably likely to have, a Public Company Material Adverse Effect.

Public Company and its Subsidiaries are in compliance with the terms of the Public Company Authorizations, except where the failure to so comply, individually or in the aggregate, has not had, and is not reasonably likely to have, a Public Company Material Adverse Effect. No Public Company Authorization shall cease to be effective as a result of the consummation of the transactions contemplated by this Agreement.

          (b) All manufacturing, processing, distribution, labeling, storage, testing, specifications, sampling, sale or marketing of products performed by or on behalf of Public Company or any of its Subsidiaries are in compliance with all applicable laws, rules, regulations or orders administered or issued by the FDA or any other Governmental Entity exercising comparable authority, except where the failure to so comply, individually or in the aggregate, has not had, and is not reasonably likely to have, a Public Company Material Adverse Effect. Neither Public Company nor any of its Subsidiaries has received any notices or correspondence from the FDA or any other Governmental Entity exercising comparable authority, and to the knowledge of Public Company there is no action or proceeding pending or threatened (including any prosecution, injunction, seizure, civil fine, suspension or recall), in each case alleging that Public Company or any of its Subsidiaries is not currently in compliance with any and all applicable laws, regulations or orders implemented by the FDA or any other Governmental Entity exercising comparable authority, except where the failure to so comply, individually or in the aggregate, has not had, and is not reasonably likely to have, a Public Company Material Adverse Effect.

          (c) There are no seizures, recalls, market withdrawals, field notifications or corrective actions, notifications of misbranding or adulteration, destruction orders, safety alerts or similar actions relating to the safety or efficacy of any products marketed or sold by Public Company or any of its Subsidiaries being conducted, requested in writing or, to the knowledge of Public Company, threatened by the FDA or any other Governmental Entity exercising comparable authority.

          (d) The studies, tests and preclinical and clinical trials conducted by or on behalf of Public Company or any of its Subsidiaries were and, if still pending, are being conducted in all material respects in accordance with experimental protocols, procedures and controls pursuant to, where applicable, accepted professional and scientific standards; and neither Public Company nor any of its Subsidiaries has received any notices or correspondence from the FDA or any other Governmental Entity exercising comparable authority requiring the termination, suspension or material modification of any studies, tests or preclinical or clinical trials conducted by or on behalf of Public Company or any of its Subsidiaries, except for such terminations, suspensions or material modifications that, individually or in the aggregate, have not had, and are not reasonably likely to have, a Public Company Material Adverse Effect.

     4.17 Employees.

          (a) Substantially all current or past key employees of Public Company or any of its Subsidiaries have entered into confidentiality and assignment of inventions agreements with Public Company, a copy or form of which has previously been provided or made available to Merger Partner. To the knowledge of Public Company, no employee of Public Company or any Subsidiary of Public Company is in violation of any term of any patent disclosure agreement, non-competition agreement, or any restrictive covenant to a former employer relating to the right of any such employee to be employed by Public Company or any of its Subsidiaries because of the nature of the business currently conducted or currently proposed to be conducted by Public Company or any of its Subsidiaries or to the use of trade secrets or proprietary information of others, the consequences of which, individually or in the aggregate, are reasonably likely to have a Public Company Material Adverse Effect.

               (i) solicit, initiate, encourage or take any other action designed to facilitate any inquiries or the making of any proposal or offer that constitutes, or could reasonably be expected to lead to, any Acquisition Proposal, including without limitation (A) approving any transaction under Section 203 of the DGCL, (B) approving any person becoming an “interested stockholder” under Section 203 of the DGCL and (C) amending or granting any waiver or release under any standstill or similar agreement with respect to any Merger Partner Common Stock or Public Company Common Stock, respectively; or

Notwithstanding the foregoing, if at any time prior to the approval of the issuance of the shares of Public Company Common Stock in the Merger at the Public Company Meeting (the “Specified Time”) Public Company receives a written Acquisition Proposal from any person or group of persons that did not result from a breach by Public Company of this Section 6.1, (A) Public Company may contact such person or group of persons to clarify the terms and conditions thereof and (B) if the Public Company Board, or any committee thereof, determines in good faith, after consultation with outside legal counsel and a nationally recognized financial advisor, that such Acquisition Proposal constitutes or could reasonably be expected to lead to a Superior Proposal, then Public Company and its Representatives may, subject to compliance with Section 6.1(c), (x) furnish information with respect to Public Company to the person making such Acquisition Proposal and its Representatives pursuant to a customary confidentiality agreement

not less restrictive of the other party than the Confidentiality Agreement and (y) participate in discussions or negotiations with such person and its Representatives regarding any Superior Proposal. Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in this Section 6.1(a) or the taking of any actions inconsistent with the restrictions set forth in this Section 6.1(a) by any Representative of Public Company or any of its Subsidiaries, whether or not such person is purporting to act on behalf of Public Company or otherwise, shall be deemed to be a breach of this Section 6.1(a) by Public Company.

          (b) No Change in Recommendation or Alternative Acquisition Agreement. Neither the Merger Partner Board nor the Public Company Board nor any committee thereof shall:

               (i) except as set forth in this Section 6.1, withdraw or modify, or publicly (or in a manner designed to become public) propose to withdraw or modify, in a manner adverse to the other party, its approval or recommendation with respect to the Merger Partner Voting Proposal or the Public Company Voting Proposals, as the case may be;

               (iii) adopt, approve or recommend, or propose to adopt, approve or recommend, any Acquisition Proposal.

Notwithstanding the foregoing, the Public Company Board may withdraw or modify its recommendation with respect to the Public Company Voting Proposals if the Public Company Board determines in good faith after consultation with outside counsel that its fiduciary obligations require it to do so, but only at a time that is prior to the Specified Time and after the fifth business day following receipt by Merger Partner of written notice advising it that the Public Company Board desires to withdraw or modify the recommendation and, if such withdrawal is due to the existence of an Acquisition Proposal, specifying the material terms and conditions of such Acquisition Proposal and identifying the person making such Acquisition Proposal. Nothing in this Section 6.1 shall be deemed to (A) permit Public Company to take any action described in clauses (ii) or (iii) of the first sentence of this Section 6.1(b), (B) affect any obligation of Public Company under this Agreement or (C) limit Public Company’s obligation to call, give notice of, convene and hold the Public Company Meeting, regardless of whether the Public Company Board has withdrawn or modified its recommendation.

Public Company shall not provide any information to or participate in discussions or

negotiations with the person or entity making any Superior Proposal until five business days after it has first notified Merger Partner of such Acquisition Proposal as required by the preceding sentence.

Contemporaneously with providing any information to a third party in connection with any such Superior Proposal or inquiry, Public Company shall furnish a copy of such information to Merger Partner.

          (d) Certain Permitted Disclosure. Nothing contained in this Section 6.1 or in Section 6.5 shall be deemed to prohibit either party from taking and disclosing to its stockholders a position with respect to a tender offer contemplated by Rule 14e-2(a) promulgated under the Exchange Act if, in the good faith judgment of the Merger Partner Board or the Public Company Board, as the case may be, after consultation with outside counsel, failure to so disclose would be inconsistent with its obligations under applicable law.

          (e) Cessation of Ongoing Discussions. Each party shall, and shall cause its Subsidiaries and its and their Representatives to, cease immediately all discussions and negotiations regarding any proposal that constitutes, or could reasonably be expected to lead to, an Acquisition Proposal.

Without limiting the generality of the foregoing, Merger Partner agrees that its obligations under this Section 6.5(a) shall not be affected by the commencement, public proposal, public

disclosure or communication to Merger Partner of any Acquisition Proposal. Within five business days after the date of the Merger Partner Stockholder Approval, Merger Partner shall send, pursuant to Section 228 of the DGCL, a written notice to all of its stockholders that did not execute a Written Consent informing them that this Agreement and the Merger were adopted and approved by the stockholders of Merger Partner and that Merger Partner will provide such stockholders information at a later date regarding their Appraisal Rights.

Public Company shall take all action that is both reasonable and lawful (including the retention of a professional proxy solicitation firm, the scope and types of services of which shall be mutually agreed upon by the parties with a view towards securing stockholder approval of the Public Company Voting Proposals) to solicit from its stockholders proxies in favor of the Public Company Voting Proposals and shall take all other action necessary or advisable to secure the vote or consent of the stockholders of Public Company required by NASDAQ rules and the DGCL, as applicable, to obtain such approvals. Notwithstanding anything to the contrary contained in this Agreement, Public Company, after consultation with Merger Partner, may adjourn or postpone the Public Company Meeting to the extent necessary to ensure that any required supplement or amendment to the Proxy Statement/Prospectus is provided to Public Company’s stockholders or, if as of the time for which the Public Company Meeting is originally scheduled (as set forth in the Proxy Statement/Prospectus) there are insufficient shares of Public Company Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Public Company Meeting.

          (c) Public Company shall call, give notice of, convene and hold the Public Company Meeting in accordance with this Section 6.5, and shall submit the Public Company Voting Proposals to its stockholders for the purpose of acting upon such proposal whether or not (i) the Public Company Board at any time subsequent to the date hereof determines, in the manner permitted by Section 6.1(b), that this Agreement is no longer advisable or recommends that the stockholders of Public Company reject such proposal, or (ii) any actual, potential or

purported Acquisition Proposal or Superior Proposal has been commenced, disclosed, announced or submitted to Public Company.

The parties hereto will consult and cooperate with one another, and consider in good faith the views of one another, in connection with any analyses, appearances, presentations, memoranda, briefs,

arguments, opinions and proposals made or submitted by or on behalf of any party hereto in connection with proceedings under or relating to any Antitrust Law. Public Company shall be entitled to direct any proceedings or negotiations with any Governmental Entity relating to any of the foregoing, provided that it shall afford Merger Partner a reasonable opportunity to participate therein. Notwithstanding anything to the contrary in this Section 6.6, neither Public Company nor any of its Subsidiaries shall be under any obligation to (i) make proposals, execute or carry out agreements or submit to orders providing for the sale or other disposition or holding separate (through the establishment of a trust or otherwise) of any material assets or categories of assets of Public Company, any of its Affiliates or Merger Partner or any of its Subsidiaries or the holding separate of the shares of Merger Partner Common Stock (or shares of stock of the Surviving Corporation) or imposing or seeking to impose any material limitation on the ability of Public Company or any of its subsidiaries or Affiliates to conduct their business or own such assets or to acquire, hold or exercise full rights of ownership of the shares of Merger Partner Common Stock (or shares of stock of the Surviving Corporation) or (ii) take any action under this Section 6.6 if the United States Department of Justice or the United States Federal Trade Commission authorizes its staff to seek a preliminary injunction or restraining order to enjoin consummation of the Merger.

          (a) For a period of six years after the Effective Time, Public Company shall maintain in effect the current level and scope of directors’ and officers’ liability insurance as in effect immediately prior to the Effective Time (a copy of which has heretofore been delivered to Merger Partner) covering those persons who are covered by Public Company’s directors’ and officers’ liability insurance policy immediately prior to the Effective Time; provided, however, that if the aggregate annual premiums for such insurance at any time during such period exceed 150% of the per annum rate of premium currently paid by Public Company for such insurance on the date hereof, then Public Company will provide the maximum coverage that will then be available at an annual premium equal to 150% of such rate. Notwithstanding the foregoing, Public Company may satisfy its obligations under this Section 6.9(a) by procuring an equivalent six-year “tail” policy under Public Company’s existing directors’ and officers’ liability insurance policy, the equivalent annual premium for which “tail” policy shall not exceed 150% of the per annum rate of premium currently paid by Public Company for directors’ and officers’ liability insurance; provided that if the equivalent annual premium for such “tail” policy exceeds 150% of the per annum rate of premium currently paid by Public Company for directors’ and officers’ liability insurance, then Public Company will provide the maximum coverage that will then be available at an equivalent annual premium equal to 150% of such rate and in doing so will be deemed to have satisfied its obligations pursuant to this Section 6.9(a).

          (b) For a period of six years after the Effective Time, Public Company shall, to the fullest extent permitted by law indemnify and hold harmless each present and former director and officer of Public Company or any of its Subsidiaries (the “Indemnified Parties”), against any costs or expenses (including attorneys’ fees), judgments, fines, losses, claims, damages, liabilities or amounts paid in settlement incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to matters existing or occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent that Public Company or one of its Subsidiaries, as the case may be, would have been permitted under Delaware law and its Certificate of Incorporation or Bylaws in effect on the date of this Agreement to indemnify an Indemnified Party (and Public Company shall also advance expenses as incurred to the fullest extent permitted under applicable law, provided the Indemnified Party to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Indemnified Party is not entitled to indemnification).

          (c) If Public Company or any of its 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 Public Company shall assume the obligations set forth in this Section 6.9.

          (d) The obligations of Public Company under this Section 6.9 shall survive the consummation of the Merger and shall not be terminated or modified in such a manner as to adversely affect any Indemnified Party to whom this Section 6.9 applies without the written consent of such affected Indemnified Party. Public Company shall pay all expenses, including

reasonable attorneys’ fees, that may be incurred by any Indemnified Party in connection with enforcement of such person’s rights provided in this Section 6.9.

          (e) The provisions of this Section 6.9 are intended to be in addition to the rights otherwise available to the officers and directors of Public Company and its Subsidiaries by law, charter, statute, bylaw or agreement, and shall operate for the benefit of, and shall be enforceable by, each of the Indemnified Parties, their heirs and their representatives as third party beneficiaries.

     6.10 Notification of Certain Matters. Public Company shall give prompt notice to Merger Partner, and Merger Partner shall give prompt notice to Public Company, of the occurrence, or failure to occur, of any event, which occurrence or failure to occur would be reasonably likely to cause (a) (i) any representation or warranty of such party contained in this Agreement that is qualified as to materiality to be untrue or inaccurate in any respect or (ii) any other representation or warranty of such party contained in this Agreement to be untrue or inaccurate in any material respect, in each case, at any time from and after the date of this Agreement until the Effective Time, or (b) any material failure of Public Company and the Transitory Subsidiary or Merger Partner, as the case may be, or of any officer, director, employee or agent thereof, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it under this Agreement. Notwithstanding the above, the delivery of any notice pursuant to this Section 6.10 will not limit or otherwise affect the remedies available hereunder to the party receiving such notice or the conditions to such party’s obligation to consummate the Merger.

     6.11 Headquarters of Public Company. Immediately following the Effective Time, the headquarters of Public Company shall be located at Merger Partner’s headquarters.

     6.12 Corporate Identity. Immediately following the Effective Time, the corporate name of Public Company shall be “Cornerstone Therapeutics Inc.”

     6.15 Employee Communications. Public Company and Merger Partner will use reasonable efforts to consult with each other, and will consider in good faith each other’s advice, prior to sending any notices or other communication materials to its employees regarding this

Agreement, the Merger or the effects thereof on the employment, compensation or benefits of its employees.

     6.16 FIRPTA Tax Certificates. On or prior to the Closing, Merger Partner shall deliver to Public Company a certificate that the Merger Partner Common Stock is not a “U.S. real property interest” in accordance with the Treasury Regulations under Sections 897 and 1445 of the Code, together with evidence reasonably satisfactory to Public Company that Merger Partner delivered notice to the Internal Revenue Service in accordance with the provisions of Section 1.897-2(h)(2) of the Treasury Regulations. If Public Company does not receive the certificate described above on or before the Closing Date, Public Company shall be permitted to withhold from the payments to be made pursuant to this Agreement any required withholding tax under Section 1445 of the Code.

          (g) by Public Company, if there has been a breach of or failure to perform any representation, warranty, covenant or agreement set forth in this Agreement (other than those referred to elsewhere in this Section 8.1) on the part of Merger Partner, which breach would cause the conditions set forth in Section 7.2(a) or (b) not to be satisfied, and such failure or breach with respect to any such representation, warranty, covenant or agreement cannot be cured

or, if curable, shall continue unremedied for a period of 30 days after Merger Partner has received written notice from Public Company of the occurrence of such failure or breach (provided that in no event shall such 30 day period extend beyond the second business day immediately preceding the Outside Date), which written notice must be provided promptly following such time as Public Company obtains actual knowledge of such failure or breach;

          (h) by Merger Partner, if there has been a breach of or failure to perform any representation, warranty, covenant or agreement set forth in this Agreement (other than those referred to elsewhere in this Section 8.1) on the part of Public Company, which breach would cause the conditions set forth in Section 7.3(a) or (b) not to be satisfied, and such failure or breach with respect to any such representation, warranty, covenant or agreement cannot be cured or, if curable, shall continue unremedied for a period of 30 days after Public Company has received written notice from Merger Partner of the occurrence of such failure or breach (provided that in no event shall such 30 day period extend beyond the second business day immediately preceding the Outside Date), which written notice must be provided promptly following such time as Merger Partner obtains actual knowledge of such failure or breach;

     8.2 Effect of Termination. In the event of termination of this Agreement as provided in Section 8.1, this Agreement shall immediately become void and there shall be no liability or obligation on the part of Public Company, Merger Partner, the Transitory Subsidiary or their respective officers, directors, stockholders or Affiliates; provided that (a) any such termination shall not relieve any party from liability for any willful breach of this Agreement (which includes without limitation the making of any representation or warranty by a party in this Agreement that the party knew was not true and accurate when made) and (b) the provisions of Section 5.3 (Confidentiality), Section 8.2 (Effect of Termination), Section 8.3 (Fees and Expenses) and

          (c) Merger Partner and Operating Company hereby agree, jointly and severally, to pay Public Company a termination fee of $1,000,000 in the event of the termination of this Agreement:

               (ii) by Public Company pursuant to Section 8.1(e), Section 8.1(g) (as a result of Merger Partner’s failure to perform any covenant or agreement described therein), Section 8.1(i) (provided that Public Company shall not have provided its notice of termination under such Section on or before the second business day immediately following the date of this Agreement) or Section 8.1(j)(ii) or (j)(iii).

               (ii) by Merger Partner or Public Company pursuant to Section 8.1(d) as a result of the failure to receive the requisite vote for approval of the Public Company Voting Proposals by the stockholders of Public Company at the Public Company Meeting if, at or prior to the time of such failure, there shall have been announced an Acquisition Proposal relating to Public Company that shall not have been absolutely and unconditionally withdrawn and abandoned; or

               (iii) by Merger Partner pursuant to Section 8.1(f) or Section 8.1(h) (as a result of Public Company’s failure to perform any covenant or agreement described therein).

of such party.

The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

Any party to this Agreement may give any notice or other communication hereunder using any other means (including personal delivery, messenger service, telecopy, ordinary mail or electronic mail), but no such notice or other communication shall be deemed to have been duly given unless and until it actually is received by the party for whom it is intended. Any party to this Agreement may change the address to which notices and other communications hereunder are to be delivered by giving the other parties to this Agreement notice in the manner herein set forth.

     9.3 Entire Agreement. This Agreement (including the Schedules and Exhibits hereto and the documents and instruments referred to herein that are to be delivered at the Closing) constitutes the entire agreement among the parties to this Agreement and supersedes any prior understandings, agreements or representations by or among the parties hereto, or any of them, written or oral, with respect to the subject matter hereof; provided that the Confidentiality Agreement shall remain in effect in accordance with its terms.

     9.4 No Third Party Beneficiaries. Except as provided in Section 6.9, and subject to Section 9.5, this Agreement is not intended, and shall not be deemed, to confer any rights or remedies upon any person other than the parties hereto and their respective successors and permitted assigns, to create any agreement of employment with any person or to otherwise create any third-party beneficiary hereto.

     9.5 Assignment. No party may assign any of its rights or delegate any of its performance obligations under this Agreement, in whole or in part, by operation of law or otherwise without the prior written consent of the other parties. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and permitted assigns. Any purported assignment of rights or delegation of performance obligations in violation of this Section 9.5 shall be null and void.

     9.6 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.

     9.7 Counterparts and Signature. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original but all of which together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the parties hereto and delivered to the other parties, it being understood that all parties need not sign the same counterpart. The exchange of copies of this Agreement or amendments thereto and of signature pages by facsimile transmission or by email transmission in portable document format, or similar format, shall constitute effective execution and delivery of such instrument(s) as to the parties and may be used in lieu of the original Agreement or amendment for all purposes. Signatures of the parties transmitted by facsimile or by email transmission in portable document format, or similar format, shall be deemed to be their original signatures for all purposes.

     9.8 Interpretation. When reference is made in this Agreement to an Article or a Section, such reference shall be to an Article or Section of this Agreement, unless otherwise indicated. The table of contents, table of defined terms and headings contained in this Agreement are for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement. The language used in this Agreement shall be deemed to be the language chosen by the parties hereto to express their mutual intent, and no rule of strict construction shall be applied against any party. Whenever the context may require, any pronouns used in this Agreement shall include the corresponding masculine, feminine or neuter forms, and the singular form of nouns and pronouns shall include the plural, and vice versa. Any reference to any federal, state, local or foreign statute or law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” No summary of this Agreement prepared by any party shall affect the meaning or interpretation of this Agreement.

     9.9 Governing Law. All matters arising out of or relating to this Agreement and the transactions contemplated hereby (including without limitation its interpretation, construction, performance and enforcement) shall be governed by and construed in accordance with the internal laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of laws of any jurisdictions other than those of the State of Delaware.

     9.10 Remedies. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and that monetary damages would not be a sufficient remedy for a breach of this Agreement. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, this being in addition to any other remedy to which they are entitled at law or in equity.

     9.11 Submission to Jurisdiction. Each of the parties to this Agreement (a) consents to submit itself to the exclusive personal jurisdiction of the Court of Chancery of the State of Delaware in any action or proceeding arising out of or relating to this Agreement or any of the transactions contemplated by this Agreement, (b) agrees that all claims in respect of such action or proceeding may be heard and determined in such court, (c) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any court and (d) agrees not to bring any action or proceeding arising out of or relating to this Agreement or any of the transaction contemplated by this Agreement in any other court. Each of the parties hereto waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety or other security that might be required of any other party with respect thereto. Any party may make service on another party by sending or delivering a copy of the process to the party to be served at the address and in the manner provided for the giving of notices in Section 9.2. Nothing in this Section 9.11, however, shall affect the right of any party to serve legal process in any other manner permitted by law.

     9.12 WAIVER OF JURY TRIAL. EACH OF PUBLIC COMPANY, THE TRANSITORY SUBSIDIARY AND MERGER PARTNER HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF PUBLIC COMPANY, THE TRANSITORY SUBSIDIARY OR MERGER PARTNER IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT.

     9.13 Operating Company Guarantee. Operating Company unconditionally guarantees to Public Company the full and complete performance by Merger Partner or the Surviving Corporation, as applicable, of its respective obligations under this Agreement and shall be liable for any breach of any representation, warranty, covenant or obligation of Merger Partner or the Surviving Corporation, as applicable, under this Agreement. This is a guarantee of payment and performance and not collectibility. Operating Company hereby waives diligence, presentment, demand of performance, filing of any claim, any right to require any proceeding first against Merger Partner or the Surviving Corporation, as applicable, protest, notice and all demands whatsoever in connection with the performance of its obligations set forth in this Section 9.13. Prior to the Effective Time, Operating Company shall not have any right of subrogation, reimbursement or indemnity whatsoever, nor any right of recourse to security for any of the

agreements, covenants and obligations of Merger Partner or the Surviving Corporation under this Agreement.

     WHEREAS, the Noteholder is the holder of that certain Promissory Note, dated April 19, 2004, with Operating Company, as amended by that certain Promissory Note Amendment and Waiver Agreement, dated June 6, 2006 (as amended, the “Carolina Note”);

     WHEREAS, as a condition and inducement to Public Company’s willingness to enter into the Merger Agreement, Public Company requires that Noteholder enter into this Agreement, (i) to covenant that Noteholder will exchange or convert the Carolina Note into the common stock, $0.0001 par value per share, of Merger Partner (the “Merger Partner Common Stock”) prior to the Effective Time in accordance with the terms hereof, (ii) to give Public Company a proxy to vote all of the shares of capital stock of Merger Partner that Noteholder owns and (iii) not to transfer or otherwise dispose of any shares of Merger Partner Common Stock that Noteholder owns or, for 180 days after the Effective Time, any Public Company Common Stock received in exchange therefor pursuant to the Merger; and

     WHEREAS, in consideration of the execution and delivery of the Merger Agreement by Public Company and the Transitory Subsidiary, Noteholder is willing to take such actions to facilitate the consummation of the Merger;

     NOW, THEREFORE, in consideration of the foregoing, intending to be legally bound, the parties hereto hereby agree as follows:

     1. Certain Definitions.

          (a) Capitalized terms used but not otherwise defined herein shall have the meanings ascribed thereto in the Merger Agreement. For purposes of this Agreement, the following terms shall have the following meanings:

          “Constructive Sale” means with respect to any security, a short sale with respect to such security, entering into or acquiring an offsetting derivative contract with respect to such security, entering into or acquiring a futures or forward contract to deliver such security or entering into any other hedging or other derivative transaction that has the effect of either directly or indirectly materially changing the economic benefits or risks of ownership.

          “Shares” means (i) all shares of capital stock of Merger Partner owned, beneficially or of record, by Noteholder as of the date hereof, and (ii) all additional shares of

capital stock of Merger Partner acquired by Noteholder, beneficially or of record, during the period commencing with the execution and delivery of this Agreement and expiring on the Expiration Date (as such term is defined in Section 11 below), including shares of Merger Partner Common Stock issued to Noteholder pursuant to Section 2 hereof.

          “Transfer” means, with respect to any security, the direct or indirect assignment, sale, transfer, tender, exchange, pledge, hypothecation, or the grant, creation or suffrage of a lien, security interest or encumbrance in or upon, or the gift, placement in trust, or the Constructive Sale or other disposition of such security (including transfers by testamentary or intestate succession or otherwise by operation of law) or any right, title or interest therein (including, but not limited to, any right or power to vote to which the holder thereof may be entitled, whether such right or power is granted by proxy or otherwise), or the record or beneficial ownership thereof, the offer to make such a sale, transfer, Constructive Sale or other disposition, and each agreement, arrangement or understanding, whether or not in writing, to effect any of the foregoing.

     2. Conversion or Exchange of Carolina Note.

          (a) Prior to the date Public Company first files the Registration Statement with the SEC, Noteholder shall surrender for cancellation the Carolina Note to Operating Company along with written instructions to Operating Company and Merger Partner to cancel the Carolina Note and issue shares of Merger Partner Common Stock in exchange for, at Noteholder’s option, all or a portion of the Carolina Note (but in an amount not less than the principal amount outstanding under the Carolina Note on the date of exchange) (such amount to be converted or exchanged, the “Purchase Amount”). Upon receipt of the surrendered Carolina Note by Operating Company, Noteholder will be deemed to be the holder of record of the shares of Merger Partner Common Stock issuable with respect to the Purchase Amount (as calculated under Section 2(b)) as of the close of business on the date the Carolina Note is surrendered to Operating Company, and Merger Partner will promptly execute or cause to be executed and delivered to Noteholder a certificate or certificates representing such number of shares. If Noteholder chooses not to convert or exchange the entire amount of principal and accrued interest then outstanding under the Carolina Note, Operating Company will, concurrently with Merger Partner’s delivery of said stock certificate or certificates, deliver to Noteholder a new promissory note of like tenor evidencing the remaining outstanding amount of the Carolina Note not so converted or exchanged for shares of Merger Partner Common Stock. Upon surrender of the Carolina Note to Operating Company by Noteholder, all shares of Merger Partner Common Stock deliverable and issued hereunder will be duly authorized, duly and validly issued and outstanding, fully paid and nonassessable, and free from taxes, liens or charges.

          (b) Upon receipt of the written instructions from Noteholder pursuant to Section 2(a), Merger Partner shall issue to Noteholder in respect of the Purchase Amount a number of shares of Merger Partner Common Stock equal to (i) the quotient of (A) the Purchase Amount, divided by (B) the fair market value of Merger Partner on the conversion or exchange date as determined in good faith by the Merger Partner Board, multiplied by (ii) the sum of (A) the number of shares of Merger Partner Common Stock outstanding immediately prior to the conversion or exchange plus (B) the number of shares of Merger Partner Common Stock issuable upon exercise of Merger Partner Stock Options and Merger Partner Warrants outstanding immediately prior to the conversion or exchange.

     3. Transfer and Voting Restrictions With Respect to the Shares.

          (a) At all times during the period commencing with the execution and delivery of this Agreement and expiring on the Expiration Date, Noteholder shall not, except in connection with the Merger or as the result of the death of Noteholder, Transfer any of the Shares, or discuss, negotiate, make

          (a) Each Stockholder hereby represents and warrants to Merger Partner as follows: (i) Stockholder is the beneficial or record owner of the shares of capital stock of Public Company indicated on the signature page of this Agreement free and clear of any and all pledges, liens, security interests, mortgage, claims, charges, restrictions, options, title defects or encumbrances; (ii) Stockholder does not beneficially own any securities of Public Company other than the shares of capital stock and rights to purchase shares of capital stock of Public Company set forth on the signature page of this Agreement; (iii) Stockholder has full power and authority to make, enter into and carry out the terms of this Agreement and to grant the irrevocable proxy as set forth in Section 4; and (iv) this Agreement has been duly and validly executed and delivered by Stockholder and constitutes a valid and binding agreement of Stockholder enforceable against Stockholder in accordance with its terms. Each Stockholder agrees to notify Merger Partner promptly of any additional shares of capital stock of Public Company of which Stockholder becomes the beneficial owner after the date of this Agreement.

          (b) As of the date hereof and for so long as this Agreement remains in effect, except for this Agreement or as otherwise permitted by this Agreement, each Stockholder has full legal power, authority and right to vote all of the Shares then owned of record or beneficially by Stockholder, in favor of the approval and authorization of the Proposed Transaction without the consent or approval of, or any other action on the part of, any other person or entity (including, without limitation, any governmental entity). Without limiting the generality of the foregoing, no Stockholder has entered into any voting agreement (other than this Agreement) with any person with respect to any of the Shares, granted any person any proxy (revocable or irrevocable) or power of attorney with respect to any of the Shares, deposited any of the Shares in a voting trust or entered into any arrangement or agreement with any person limiting or affecting Stockholder’s legal power, authority or right to vote the Shares on any matter.

          (c) The execution and delivery of this Agreement and the performance by each Stockholder of his, her or its agreements and obligations hereunder will not result in any breach or violation of or be in conflict with or constitute a default under any term of any agreement, judgment, injunction, order, decree, law, regulation or arrangement to which Stockholder is a party or by which Stockholder (or any of his, her or its assets) is bound, except for any such breach, violation, conflict or default which, individually or in the aggregate, would not impair or adversely affect Stockholder’s ability to perform his, her or its obligations under this Agreement or render inaccurate any of the representations made by Stockholder herein.

          (d) Except as disclosed pursuant to the Merger Agreement, no investment banker, broker, finder or other intermediary is entitled to a fee or commission from Public Company, the Transitory Subsidiary or Merger Partner in respect of this Agreement based upon any arrangement or agreement made by or on behalf of any Stockholder.

          (e) Each Stockholder understands and acknowledges that Public Company, the Transitory Subsidiary and Merger Partner are entering into the Merger Agreement in reliance upon Stockholder’s execution and delivery of this Agreement and the representations and warranties of Stockholder contained herein.

     8. Confidentiality. Each Stockholder recognizes that successful consummation of the Proposed Transaction may be dependent upon confidentiality with respect to the matters referred to herein. In this connection, pending public disclosure thereof, and so that Public Company may rely on

the safe harbor provisions of Rule 100(b)(2)(ii) of Regulation FD promulgated under the Exchange Act, each Stockholder hereby agrees not to disclose or discuss such matters with anyone not a party to this Agreement (other than its counsel and advisors, if any) without the prior written consent of Public Company and Merger Partner, except for disclosures Stockholder’s counsel advises are required by applicable law, in which case Stockholder shall give notice of such disclosure to Public Company and Merger Partner as promptly as practicable so as to enable Public Company and Merger Partner to seek a protective order from a court of competent jurisdiction with respect thereto.

     9. Termination. This Agreement shall terminate and be of no further force or effect whatsoever as of the earlier of (a) such date and time as the Merger Agreement shall have been validly terminated pursuant to the terms of Article 8 thereof or (b) the Effective Time (the “Expiration Date”).

     10. Miscellaneous Provisions.

          (a) Amendments, Modifications and Waivers. This Agreement may not be amended or modified except by an instrument in writing signed on behalf of each of the parties hereto. Any agreement on the part of a party hereto to any waiver of any term or condition hereof shall be valid only if set forth in a written instrument signed on behalf of such party. Such waiver shall not be deemed to apply to any term or condition other than that which is specified in such waiver. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

          (b) Entire Agreement. This Agreement constitutes the entire agreement among the parties to this Agreement and supersedes any prior understandings, agreements or representations by or among the parties hereto, or any of them, written or oral, with respect to the subject matter hereof.

          (c) Governing Law. All matters arising out of or relating to this Agreement and the transactions contemplated hereby (including without limitation its interpretation, construction, performance and enforcement) shall be governed by and construed in accordance with the internal laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of laws of any jurisdictions other than those of the State of Delaware.

          (d) Submission to Jurisdiction. Each of the parties to this Agreement (i) consents to submit itself to the exclusive personal jurisdiction of the Chancery Court of the State of Delaware in any action or proceeding arising out of or relating to this Agreement or any of the transactions contemplated by this Agreement, (ii) agrees that all claims in respect of such action or proceeding may be heard and determined in such court, (iii) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from such court and (d) agrees not to bring any action or proceeding arising out of or relating to this Agreement or any of the transaction contemplated by this Agreement in any other court. Each of the parties hereto waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety or other security that might be required of any other party with respect thereto. Any party may make service on another party by sending or delivering a copy of the process to the party to be served at the address and in the manner provided for the giving of notices in Section 10(m) hereof. Nothing in this Section 10(d), however, shall affect the right of any party to serve legal process in any other manner permitted by law.

          (e) WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED

HEREBY OR THE ACTIONS OF ANY PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT.

          (f) Attorneys’ Fees. In any action at law or suit in equity to enforce this Agreement or the rights of any of the parties hereunder, the prevailing party in such action or suit shall be entitled to receive its reasonable attorneys’ fees and all other reasonable costs and expenses incurred in such action or suit.

          (g) Assignment and Successors. No party may assign any of its rights or delegate any of its performance obligations under this Agreement, in whole or in part, by operation of law or otherwise without the prior written consent of the other parties, except that Merger Partner, without obtaining the consent of any other parties hereto, shall be entitled to assign this Agreement or all or any of its rights or obligations hereunder to any one or more of its Affiliates. No assignment by Merger Partner under this Section 10(g) shall relieve Merger Partner of its obligations under this Agreement. Subject to the foregoing, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and permitted assigns, including, without limitation, Stockholder’s estate and heirs upon the death of Stockholder. Any purported assignment of rights or delegation of performance obligations in violation of this Section 10(g) shall be null and void.

          (h) No Third Party Beneficiaries. This Agreement is not intended, and shall not be deemed, to confer any rights or remedies upon any person other than the parties hereto and their respective successors and permitted assigns, or to otherwise create any third-party beneficiary hereto.

          (i) Cooperation. Each Stockholder agrees to cooperate fully with Merger Partner and to execute and deliver such further documents, certificates, agreements and instruments and to take such other actions as may be reasonably requested by Merger Partner to evidence or reflect the transactions contemplated by this Agreement and to carry out the intent and purpose of this Agreement. Each Stockholder hereby agrees that Public Company and Merger Partner may publish and disclose in the Registration Statement and any resale registration statement relating thereto (including all documents and schedules filed with the SEC) and the Proxy Statement/Prospectus, each such Stockholder’s identity and ownership of Shares and the nature of such Stockholder’s commitments, arrangements and understandings under this Agreement and may further file this Agreement as an exhibit to the Registration Statement or in any other filing made by Public Company or Merger Partner with the SEC relating to the Proposed Transaction.

          (j) Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.

          (k) Time of Essence. With regard to all dates and time periods set forth or referred to in this Agreement, time is of the essence.

          (l) Specific Performance; Injunctive Relief. The parties hereto acknowledge that Public Company and Merger Partner shall be irreparably harmed and that there shall be no adequate remedy at law for a violation of any of the covenants or agreements of each Stockholder set forth in this Agreement. Each Stockholder accordingly agrees that, in addition to any other remedies that may be available to Public Company or Merger Partner, as applicable upon any such violation, such party shall have the right to enforce such covenants and agreements by specific performance, injunctive relief or by any other means available to such party at law or in equity without posting any bond or other undertaking.

          (m) Notices. All notices and other communications hereunder shall be in writing and shall be deemed duly delivered (i) four business days after being sent by registered or certified mail, return receipt requested, postage prepaid, or (ii) one business day after being sent for next business day delivery, fees prepaid, via a reputable nationwide overnight courier service, in each case to the intended recipient as follows: (A) if to Public Company or Merger Partner, to the address provided in the Merger Agreement, including to the persons designated therein to receive copies, and (B) if to any Stockholder, to such Stockholder’s address shown below Stockholder’s signature on the signature page hereof.

          (n) Counterparts and Signature. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original but all of which together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the parties hereto and delivered to the other parties, it being understood that all parties need not sign the same counterpart. The exchange of copies of this Agreement of amendments thereto and of signature pages by facsimile transmission or by email transmission in portable document format, or similar format, shall constitute effective execution and delivery of such instrument(s) as to the parties and may be used in lieu of the original Agreement for all purposes. Signatures of the parties transmitted by facsimile or by email transmission in portable document format, or similar format, shall be deemed to be their original signatures for all purposes.

          (o) Headings. The headings contained in this Agreement are for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement.

          (p) Legal Representation. This Agreement was negotiated by the parties with the benefit of legal representation and any rule of construction or interpretation otherwise requiring this Agreement to be construed or interpreted against any party shall not apply to any construction or interpretation thereof.

CERTIFICATE OF INCORPORATION

OF

CORNERSTONE BIOPHARMA HOLDINGS, INC.

     FIRST: The name of the Corporation is: Cornerstone BioPharma Holdings, Inc.

     SECOND: The address of the Corporation’s registered office in the State of Delaware is Corporation Trust Center, ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇ ▇▇▇ ▇▇▇▇ ▇▇ ▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇ of New Castle. The name of its registered agent at such address is The Corporation Trust Company.

     THIRD: The nature of the business or purposes to be conducted or promoted by the Corporation is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware.

     FOURTH: The total number of shares of stock which the Corporation shall have authority to issue is 1,000 shares of Common Stock, $0.001 par value per share.

     The number of authorized shares of Common Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the stock of the Corporation entitled to vote, irrespective of the provisions of Section 242(b)(2) of the General Corporation Law of the State of Delaware.

     FIFTH: In furtherance of and not in limitation of powers conferred by statute, it is further provided:

          1. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors.

          2. Election of directors need not be by written ballot.

          3. The Board of Directors is expressly authorized to adopt, amend, alter or repeal the Bylaws of the Corporation.

     SIXTH: Except to the extent that the General Corporation Law of the State of Delaware prohibits the elimination or limitation of liability of directors for breaches of fiduciary duty, no director of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for any breach of fiduciary duty as a director, notwithstanding any provision of law imposing such liability. No amendment to or repeal of this provision shall apply to or have any effect on the liability or alleged liability of any director of the Corporation for or with respect to any acts or omissions of such director occurring prior to such amendment.

     SEVENTH: The Corporation shall, to the fullest extent permitted by Section 145 of the General Corporation Law of the State of Delaware, as amended from time to time, indemnify each person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative,

by reason of the fact that he or she is or was, or has agreed to become, a director or officer of the Corporation, or is or was serving, or has agreed to serve, at the request of the Corporation, as a director, officer, partner, employee or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise (including any employee benefit plan) (all such persons being referred to hereafter as an “Indemnitee”), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by or on behalf of an Indemnitee in connection with such action, suit or proceeding and any appeal therefrom.

     As a condition precedent to an Indemnitee’s right to be indemnified, the Indemnitee must notify the Corporation in writing as soon as practicable of any action, suit, proceeding or investigation involving such Indemnitee for which indemnity will or could be sought. With respect to any action, suit, proceeding or investigation of which the Corporation is so notified, the Corporation will be entitled to participate therein at its own expense and/or to assume the defense thereof at its own expense, with legal counsel reasonably acceptable to the Indemnitee.

     In the event that the Corporation does not assume the defense of any action, suit, proceeding or investigation of which the Corporation receives notice under this Article, the Corporation shall pay in advance of the final disposition of such matter any expenses (including attorneys’ fees) incurred by an Indemnitee in defending a civil or criminal action, suit, proceeding or investigation or any appeal therefrom; provided, however, that the payment of such expenses incurred by an Indemnitee in advance of the final disposition of such matter shall be made only upon receipt of an undertaking by or on behalf of the Indemnitee to repay all amounts so advanced in the event that it shall ultimately be determined that the Indemnitee is not entitled to be indemnified by the Corporation as authorized in this Article, which undertaking shall be accepted without reference to the financial ability of the Indemnitee to make such repayment; and provided, further, that no such advancement of expenses shall be made under this Article if it is determined that (i) the Indemnitee did not act in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the Corporation, or (ii) with respect to any criminal action or proceeding, the Indemnitee had reasonable cause to believe his conduct was unlawful.

     The Corporation shall not indemnify an Indemnitee pursuant to this Article in connection with a proceeding (or part thereof) initiated by such Indemnitee unless the initiation thereof was approved by the Board of Directors of the Corporation. In addition, the Corporation shall not indemnify an Indemnitee to the extent such Indemnitee is reimbursed from the proceeds of insurance, and in the event the Corporation makes any indemnification payments to an Indemnitee and such Indemnitee is subsequently reimbursed from the proceeds of insurance, such Indemnitee shall promptly refund such indemnification payments to the Corporation to the extent of such insurance reimbursement.

     All determinations hereunder as to the entitlement of an Indemnitee to indemnification or advancement of expenses shall be made in each instance (a) by a majority vote of the directors of the Corporation consisting of persons who are not at that time parties to the action, suit or

proceeding in question (“disinterested directors”), whether or not a quorum, (b) by a committee of disinterested directors designated by majority vote of disinterested directors, whether or not a quorum, (c) if there are no disinterested directors, or if the disinterested directors so direct, by independent legal counsel (who may, to the extent permitted by law, be regular legal counsel to the Corporation) in a written opinion, or (d) by the stockholders of the Corporation.

     The rights provided in this Article (i) shall not be deemed exclusive of any other rights to which an Indemnitee may be entitled under any law, agreement or vote of stockholders or disinterested directors or otherwise, and (ii) shall inure to the benefit of the heirs, executors and administrators of the Indemnitees. The Corporation may, to the extent authorized from time to time by its Board of Directors, grant indemnification rights to other employees or agents of the Corporation or other persons serving the Corporation and such rights may be equivalent to, or greater or less than, those set forth in this Article.

     EIGHTH: The Corporation reserves the right to amend, alter, change or repeal any provision contained in this Certificate of Incorporation, in the manner now or hereafter prescribed by statute and this Certificate of Incorporation, and all rights conferred upon stockholders herein are granted subject to this reservation.
