AGREEMENT AND PLAN OF MERGER

            This AGREEMENT AND PLAN OF MERGER (this "Agreement") is made and entered into as of December 13, 2006 by and among Forest Laboratories, Inc., a Delaware corporation ("Acquiror"), FL Acquisition Corp., a Delaware corporation which is a wholly-owned subsidiary of Acquiror ("Merger Sub"), Cerexa, Inc., a Delaware corporation ("Target"), and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ and ▇▇▇▇▇▇ ▇▇▇▇▇, as Stockholders’ Agent (solely for purposes of Section 5.12, Section 5.13 and Section 8). Acquiror, Merger Sub and Target may be referred to herein individually as a "Party", and collectively as the "Parties". Capitalized terms used in this Agreement shall have the meanings ascribed to such term in Exhibit A of this Agreement, or if applicable as provided in the text of this Agreement.

RECITALS

            A.        The Boards of Directors of Target, Acquiror and Merger Sub believe it is in the best interests of their respective companies and the stockholders of their respective companies for Target and Merger Sub to combine into a single company through the statutory merger of Merger Sub with and into Target (the "Merger") and, in furtherance thereof, have approved this Agreement and the Merger.

            B.        In connection with the Merger, the outstanding shares of Target’s capital stock will be converted into the right to receive the cash amount described in this Agreement.

            C.        Acquiror, Target and the Stockholders’ Agent will enter into an Escrow Agreement to be executed and delivered in accordance with Section 5.5 (the "Escrow Agreement").

            D.        Target, Acquiror and Merger Sub desire to make certain representations and warranties and enter into certain covenants in connection with the Merger.

            E.        As an inducement to the Acquiror to enter into this Agreement, certain holders of Target Capital Stock (the "Majority Holders") having voting power equal to or greater than the Required Stockholder Vote have indicated their intention to deliver, as promptly as practicable following the execution of this Agreement, their irrevocable approval of the Merger, this Agreement and the transactions contemplated hereby pursuant to a written consent, substantially in the form attached hereto as Exhibit B (the "Written Consent"), signed and dated by the Majority Holders in their capacity as Target stockholders as promptly as practicable following the execution of this Agreement, pursuant to and in strict accordance with the applicable provisions of the Delaware Law, the Target certificate of incorporation and the Target bylaws.

            NOW, THEREFORE, in consideration of the covenants, representations and warranties set forth herein, and for other good and valuable consideration, the Parties, intending to be legally bound, agree as follows:

            1. The Merger.

                      1.1         The Merger. At the Effective Time and upon the terms and subject to the conditions set forth in this Agreement, in the Certificate of Merger filed pursuant to Section 1.2 and in the applicable provisions of the Delaware General Corporation Law ("Delaware Law"), Merger Sub shall be merged with and into Target, the separate corporate existence of Merger Sub shall cease and Target shall continue as the surviving corporation in the Merger (the "Surviving Corporation").

                      1.2         Closing; Effective Time. The consummation of the Merger (the "Closing") shall take place as soon as practicable, but no later than two Business Days, after the satisfaction or waiver of the last of the conditions set forth in Section 6 to be satisfied or waived (other than those conditions that by their nature are to be satisfied at the Closing), or at such other time as the Parties agree (the actual date on which the Closing takes place being the "Closing Date"). The Closing shall take place at the offices of Cooley Godward Kronish LLP, ▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, or at such other location as the Parties agree. In connection with the Closing, Target shall cause the Merger to be made effective by filing the Certificate of Merger in substantially the form attached hereto as Schedule 1.2 with the Secretary of State of the State of Delaware in accordance with the relevant provisions of Delaware Law (the time of such filing or such later time as agreed to by the Parties and provided in the Certificate of Merger being the "Effective Time").

                      1.3         Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in this Agreement, the Certificate of Merger filed pursuant to Section 1.2 and the applicable provisions of Delaware Law.

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

                                   (a)        the certificate of incorporation of Target shall be amended to read as set forth in Exhibit C, and as so amended shall be the certificate of incorporation of the Surviving Corporation until thereafter amended as provided by Delaware Law and such certificate of incorporation; and

                                   (b)        the bylaws of Merger Sub, as in effect immediately prior to the Effective Time, shall be the bylaws of the Surviving Corporation until thereafter amended.

                      1.5         Directors and Officers. At the Effective Time, the directors and officers of Merger Sub immediately prior to the Effective Time shall be the directors and officers of the Surviving Corporation, to serve until their respective successors are duly elected or appointed and qualified.

                      1.6         Effect on Capital Stock. Subject to Sections 1.7(a), 8.1 and 8.3(a), at the Effective Time, by virtue of the Merger and without any further action on the part of Acquiror, Merger Sub, Target, the Stockholders’ Agent or the holders of any of the securities identified below:

                                   (a)        each share of Target Common Stock, Series A Preferred Stock and Series B Preferred Stock issued and outstanding immediately prior to the Effective Time (excluding Dissenting Shares and shares owned by Target, Acquiror, Merger Sub or any of their respective wholly owned subsidiaries) shall be converted into the right to receive (without interest) (i) an amount of cash equal to (A) the Merger Consideration divided by the sum of (1) the aggregate number of shares of Target Capital Stock outstanding immediately prior to the Effective Time plus (2) the aggregate number of shares of Target Capital Stock subject to unexercised Target Options (whether vested or unvested) that are outstanding immediately prior to the Effective Time (the amount determined pursuant to this subclause (A) being the "Per Share Price"); minus (B) the Escrow Contribution Amount per share of Target Capital Stock; plus (C) any cash disbursements required to be made from the Escrow Fund with respect to such share to the Former Holder thereof in accordance with the terms of the Escrow Agreement, as and when such disbursements are required to be made; plus (ii) if the Milestone Event occurs, an amount of cash equal to the Additional Merger Consideration divided by the sum of (1) the aggregate number of shares of Target Capital Stock outstanding immediately prior to the Effective Time plus (2) the aggregate number of shares of Target Capital Stock subject to unexercised Target Options (whether vested or unvested) that are outstanding immediately prior to the Effective Time;

                                   (b)        each share of Target Capital Stock that is owned by Target as treasury stock, or by Acquiror or Merger Sub or any of their respective wholly owned subsidiaries, shall automatically be canceled and shall cease to exist, and no consideration shall be delivered in exchange therefore; and

                                   (c)        each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into one share of common stock of the Surviving Corporation.

            The amount of cash, if any, that each Former Holder of Target is entitled to receive for the shares of Target Capital Stock held by such Former Holder and/or Target Options held by such Former Holder (as provided in Section 1.11) shall be rounded to the nearest cent (with $0.005 being rounded upward) and computed after aggregating the cash amounts payable for all shares of each class and series of Target Capital Stock held by such Former Holder and all Target Options held by such Former Holder,

                      1.7        Cancellation and Surrender of Certificates.

                                   (a)         No Further Rights as Target Stockholders. At the Effective Time, all shares of Target Capital Stock outstanding immediately prior to the Effective Time shall automatically be cancelled and retired and shall cease to exist, and no holder of record of a certificate that immediately prior to the Effective Time represented outstanding shares of Target Capital Stock (a "Certificate") shall have any rights as a stockholder of Target.

                                   (b)         Exchange Procedures. Upon surrender of a Certificate for cancellation to Acquiror, together with a letter of transmittal in form reasonably acceptable to Acquiror (which letter of transmittal shall include an undertaking of the signatory thereto not to violate Section 1.13 hereof) providing that risk of loss shall pass only upon delivery of such certificates to Acquiror, duly completed and validly executed in accordance with the instructions thereto, (i) the holder of such Certificate shall be entitled to receive in exchange therefor cash in an amount equal to the share of the Merger Consideration which such holder has the right to receive pursuant to Section 1.6(a), and (ii) the Certificate so surrendered shall forthwith be canceled. Acquiror shall: (x) as promptly as practicable after receipt of each properly surrendered Certificate, but in no event later than five Business Days after such receipt, cause the payment described in the preceding sentence (not including any amounts covered by Section 1.6(a)(i)(C) or Section 1.6(a)(ii)) to be made to the holder of such Certificate by wire transfer of immediately available funds to the account designated by such holder in the letter of transmittal delivered with such Certificate, and (y) if the Milestone Event occurs, as promptly as practicable thereafter, but in no event later than forty-five days after such occurrence, cause the payment described in Section 1.6(a)(ii) to be made to the holder of such Certificate by wire transfer of immediately available funds to the account designated by such holder in the letter of transmittal delivered with such Certificate (or such other account as designated in writing by such holder). Until so surrendered, each outstanding Certificate that prior to the Effective Time represented shares of Target Capital Stock (other than Dissenting Shares) will be deemed from and after the Effective Time, for all purposes, to evidence the right to receive the amount equal to the share of the Merger Consideration which such holder has the right to receive pursuant to Section 1.6(a). If, after the Effective Time, any Certificate is presented to the Surviving Corporation or Acquiror, it shall be cancelled and exchanged as provided in this Section 1.7.

                                   (c)         Transfers of Ownership. After the Effective Time, there shall be no further registration of transfers of shares of Target Capital Stock outstanding immediately prior to the Effective Time on the records of Target.

                                   (d)         No Liability. Notwithstanding anything to the contrary in this Section 1.7, neither Acquiror nor the Surviving Corporation or any other party hereto shall be liable to any person for any amount properly paid to a public official pursuant to any applicable abandoned property law, escheat law or similar law. Any amounts remaining unclaimed by Former Holders two years after the Effective Time (or such earlier date which is immediately prior to such time as the amounts would otherwise escheat to or become the property of any Governmental Authority) shall become, to the fullest extent permitted by Applicable Laws, the property of the Acquiror, free and clear of any claims or interests of any Person previously entitled thereto.

                      1.8         Lost, Stolen or Destroyed Certificates. In the event any Certificate shall have been lost, stolen or destroyed, Acquiror shall pay to the record holder of such Certificate the consideration into which the shares of Target Capital Stock formerly represented by such Certificate have been converted pursuant to Section 1.6, upon the making of an affidavit of that fact by such record holder; provided, however, that Acquiror may, in its discretion and as a condition precedent to the payment of such consideration, require such record holder to deliver a bond in such sum as Acquiror may reasonably direct as indemnity against any claim that may be made against Acquiror or the Surviving Corporation with respect to such Certificate.

                      1.9         Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, any Dissenting Share shall not be converted into the right to receive the consideration to which the holder of such share (a "Dissenting Stockholder") would be entitled pursuant to Section 1.6, but rather shall be entitled to receive such amount as may be determined to be due with respect to such Dissenting Share pursuant to Delaware Law. If any Dissenting Stockholder fails to perfect such stockholder’s dissenters’ rights under Delaware Law or effectively withdraws or otherwise loses such rights with respect to any Dissenting Shares, such Dissenting Shares shall thereupon automatically be converted into the right to receive the consideration referred to in Section 1.6, pursuant to the exchange procedures set forth in Section 1.7. Target shall give Acquiror (a) prompt notice of any demand for payment of the fair value of any shares of Target Capital Stock or any attempted withdrawal of any such demand for payment and any other instrument served pursuant to Delaware Law and received by Target relating to any stockholder’s dissenters’ rights, and (b) the opportunity to direct all negotiations and proceedings with respect to any such demands for payment under Delaware Law.

                      1.10        Taking of Further Action. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of Target and Merger Sub, Acquiror and the Surviving Corporation are fully authorized in their respective names to take, and will take, all such lawful and necessary or desirable action, so long as such action is not inconsistent with this Agreement.

                      1.11        Target Options. As soon as practicable following the date of this Agreement, the Board of Directors of Target (or, if appropriate, any committee thereof administering the 2005 Equity Incentive Plan) shall adopt such resolutions or take such other actions as may be required to adjust the terms of all outstanding Target Options, whether vested or unvested, as necessary to provide that Target Options will become fully exercisable and may be exercised before the Effective Time at such applicable time or times as specified in the 2005 Equity Incentive Plan, and at the Effective Time, each Target Option outstanding immediately prior to the Effective Time, whether or not then vested or exercisable, shall be canceled and the holder thereof shall then become entitled to receive, in full satisfaction of the rights of such holder with respect thereto, an amount equal to: (a) an amount of cash equal to (i) the product of (A) the number of shares of Target Common Stock subject to such Target Option immediately prior to the Effective Time, multiplied by (B) the amount by which the Per Share Price exceeds the exercise price per share of Target Common Stock that is subject to such Target Option; minus (ii) the Escrow Contribution Amount for such Target Option; plus (iii) any cash disbursements required to be made from the Escrow Fund with respect to such Target Option to the Former Optionholder thereof in accordance with the terms of the Escrow Agreement, as and when such disbursements are required to be made; plus (b) if the Milestone Event occurs, an amount of cash equal to the product of (i) the number of shares of Target Common Stock subject to such Target Option immediately prior to the Effective Time, multiplied by (ii) an amount equal to (A) the Additional Merger Consideration divided by (B) the sum of (1) the aggregate number of shares of Target Capital Stock outstanding immediately prior to the Effective Time plus (2) the aggregate number of shares of Target Capital Stock subject to unexercised Target Options (whether vested or unvested) that are outstanding immediately prior to the Effective Time. As soon as practicable following the Effective Time, Acquiror shall cause the payment described in subsections (a)(i), as reduced by subsection (a)(ii), of the preceding sentence to be made to the holder of such Target Option by wire transfer of immediately available funds to the account designated by such holder in writing, and such holder shall remain entitled to receive any additional cash disbursements as provided in subclause (a)(iii) and subclause (b) (if applicable). If the Milestone Event occurs, Acquiror shall, as promptly as practicable thereafter, but in no event later than forty-five days after such occurrence, cause the payment described in Section 1.11(b) to be made to the holder of such Target Option by wire transfer of immediately available funds to the account designated by such holder in writing.

                      1.12        Withholding Rights. Acquiror shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to this Article 1 such withholding, employment and similar taxes and all other amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of federal, state, local or foreign law. If the Acquiror so withholds amounts, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Target Capital Stock or Target Options in respect of whom the Acquiror made such deduction and withholding.

                      1.13        Non-Transferability of Contingent Rights. No Former Holder shall directly or indirectly sell, assign, gift, pledge, hypothecate, or otherwise voluntarily or involuntarily or by operation of law encumber, transfer or dispose of (other than pursuant to the laws of descent and distribution or by will) (each a "Transfer") any of its rights to receive consideration under Section 1.6(a)(ii) or 1.11(b), and neither the Surviving Corporation nor Acquiror shall be obligated to effect or recognize a Transfer prohibited by this Section 1.13. The right to receive consideration under Section 1.6(a)(ii) or 1.11(b) shall not constitute an equity interest in Acquiror or the Surviving Corporation and shall not vest in or otherwise provide any Former Holder with any voting rights or other rights of ownership of any security.

            2. Representations and Warranties of Target. Target represents and warrants to Acquiror as of the date of this Agreement (for all purposes except for purposes of Section 8), and as of the date of this Agreement and as of the Closing Date (for purposes of Section 8) that the statements contained in this Section 2 are true and correct except as disclosed in a disclosure schedule of even date herewith delivered by Target to Acquiror and complying with the provisions of Section 9.2 (the "Target Disclosure Schedule"):

                      2.1         Organization, Standing and Power. Each of Target and its Subsidiaries is a corporation duly organized, validly existing and in good standing, if applicable, under the laws of the jurisdiction of its incorporation. There is no pending or, to the knowledge of Target, threatened action for the dissolution, liquidation or insolvency of Target or any of its Subsidiaries. Target and its Subsidiaries have the corporate power to own their properties and to carry on their business as now being conducted (collectively, the "Current Target Business"). Each of Target and its Subsidiaries is duly qualified to do business, and is in good standing (if such concept is applicable in the relevant jurisdiction), in each jurisdiction where the operation of the Current Target Business by Target and its Subsidiaries requires such qualification. Target has delivered, or made available for review in a data room, to Acquiror or its advisors true and correct copies of the respective certificates of incorporation and bylaws or other equivalent organizational documents, as applicable, of Target and each of its Subsidiaries, each as in effect as of the date of this Agreement. The minute books of Target and its Subsidiaries have been made available in a data room for review by Acquiror or its advisors and contain a materially complete and accurate summary of all meetings of directors and stockholders or actions by written consent since the time of incorporation of each such company through the date of this Agreement. Neither Target nor any of its Subsidiaries is in violation of any of the provisions of its certificate of incorporation or bylaws or equivalent organizational documents. Target has no Subsidiaries other than those listed in Section 0 of Target Disclosure Schedule, and neither Target nor any such Subsidiary owns directly or indirectly any equity or similar interest in, or any interest convertible or exchangeable or exercisable for, any equity or similar interest in, any corporation, partnership, joint venture or other business association or entity.

                      2.2         Authority. Target has all requisite corporate power and authority to enter into this Agreement and to consummate the Merger. The affirmative vote or consent of the holders of (i) a majority of the shares of Target Common Stock and Target Preferred Stock (voting together as a single class) outstanding on the record date chosen for purposes of determining the stockholders of Target entitled to vote on the adoption of this Agreement, (ii) a majority of the shares of Target Preferred Stock (voting together as a single class) outstanding on the record date chosen for purposes of determining the stockholders of Target entitled to vote on the adoption of this Agreement and (iii) at least 60% of the shares of Target Series B Preferred Stock outstanding on the record date chosen for purposes of determining the stockholders of Target entitled to vote on the adoption of this Agreement are the only votes of the holders of any Target Capital Stock necessary under Delaware Law and the Certificate of Incorporation of Target to approve this Agreement and the Merger (the "Required Stockholder Vote"). The Board of Directors of Target has unanimously (a) adopted this Agreement and declared it advisable and approved its execution and delivery and the consummation of the Merger; (b) determined that the Merger is in the best interests of the stockholders of Target, and (c) recommended that the holders of Target Capital Stock approve this Agreement and the Merger and the transactions contemplated by this Agreement. This Agreement has been duly executed and delivered by Target and, assuming this Agreement constitutes a valid and binding obligation of the other parties hereto, this Agreement constitutes a valid and binding obligation of Target, enforceable against Target in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, moratorium or other similar laws affecting or relating to creditors’ rights generally and general principles of equity, regardless of whether asserted in a proceeding in equity or at law. The execution and delivery of this Agreement by Target does not constitute, and the consummation by Target of the transactions contemplated hereby will not result in, a termination, or breach or violation by Target of, or a default by Target under (with or without notice or lapse of time, or both), (a) any provision of the certificate of incorporation or bylaws of Target, as amended, (b) any Material Contract or (c) any judgment, order, decree, statute, law, ordinance, rule or regulation applicable to Target or any of its properties or assets. No material consent, approval, order or authorization of, or registration, declaration or filing with, any court, administrative agency or commission or other governmental authority or instrumentality (each, a "Governmental Entity") is required to be obtained or made by Target at or prior to the Effective Time in order for Target to execute and deliver this Agreement or consummate the Merger, except for: (a) the filing of Certificate of Merger as provided in Section 0 and (b) such filings as may be required under the ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Antitrust Improvements Act of 1976, as amended ("HSR"), and foreign antitrust laws. The holders of Target Capital Stock are not entitled to appraisal, dissenter’s or similar rights under any Applicable Laws except as provided in Section 262 of the Delaware Law ("Section 262").

                      2.3         Governmental Authorizations. Target and its Subsidiaries have obtained each material federal, state, county, local or foreign governmental consent, license, permit, grant or other authorization of a Governmental Entity that is required, as of the date hereof, for the operation by Target and its Subsidiaries of the Current Target Business, and all of such consents, licenses, permits, grants and authorizations are in full force and effect.

                      2.4         Financial Statements. Target has delivered to Acquiror or its advisors (a) the audited consolidated balance sheets and statements of operations of Target and its Subsidiaries as of and for the fiscal year ended December 31, 2005 and (b)(i) the unaudited consolidated balance sheet of Target and its Subsidiaries as of September 30, 2006 (the "Target Balance Sheet") and (ii) the unaudited consolidated statement of operations of Target and its Subsidiaries for the nine-month period ended September 30, 2006 (collectively, the "Target Financial Statements"). The Target Financial Statements have been prepared in accordance with GAAP (except as disclosed in the notes thereto and except that the unaudited Target Financial Statements do not contain footnotes and are subject to normal year-end audit adjustments) applied on a consistent basis throughout the periods covered. The Target Financial Statements fairly present, in all material respects and in accordance with GAAP, the financial condition of Target as of the dates indicated therein and the operating results of Target for the periods indicated therein, subject to normal year-end audit adjustments and the absence of footnotes in the case of the unaudited Target Financial Statements.

                      2.5         Capitalization; Shares and Stockholder Information.

                                   (a)         Capitalization. The authorized capital stock of Target consists of (i) 84,000,000 shares of Target Common Stock, of which there were issued and outstanding as of the date of this Agreement, 9,750,249 shares, and (ii) 64,000,000 shares of Target Preferred Stock, of which as of the date of this Agreement 20,000,000 were designated Series A Preferred Stock and 44,000,000 were designated Series B Preferred Stock. As of the date of this Agreement, there were issued and outstanding: 20,000,000 shares of Series A Preferred Stock convertible into the same number of shares of Common Stock, and 42,176,299 shares of Series B Preferred Stock convertible into the same number of shares of Common Stock. Each outstanding share of Series A Preferred Stock and Series B Preferred Stock is convertible into one share of Target Common Stock. All outstanding shares of Target Common Stock and Target Preferred Stock (i) are duly authorized, validly issued, fully paid and non-assessable, (ii) are free of any liens or encumbrances created by Target, and, to the knowledge of Target, free of any liens or encumbrances created by or imposed upon the holders thereof and (iii) were not issued in violation of any preemptive rights or rights of first refusal created by statute, the certificate of incorporation or bylaws of Target or any agreement to which Target is a party or by which it is bound. As of the date of this Agreement, there were 14,584,563 shares of Target Common Stock reserved for issuance under the 2005 Equity Incentive Plan, of which 4,672,674 shares of Target Common Stock were subject to outstanding options and 161,640 shares of Target Common Stock were reserved for future option grants. Target has delivered to Acquiror or its advisors (or made available in a data room) true and complete copies of the 2005 Equity Incentive Plan and each form of agreement evidencing each Target Option (and each such agreement accurately reflects the actual date of grant of such Target Option determined in accordance with GAAP). Except for the rights created pursuant to this Agreement and the options and other rights disclosed in the preceding sentences, there are no options, warrants, calls, rights, commitments or agreements that are outstanding to which Target is a party or by which it is bound, obligating Target to issue, deliver, sell, repurchase or redeem, or cause to be issued, delivered, sold, repurchased or redeemed, any shares of Target Capital Stock or other equity securities of Target or its Subsidiaries or obligating Target to grant, extend, accelerate the vesting of, change the price of, or otherwise amend or enter into any option, warrant, call, right, commitment or agreement regarding shares of Target Capital Stock or other equity securities of Target or its Subsidiaries. All shares of Target Common Stock issuable upon conversion of the outstanding shares of Target Preferred Stock or upon exercise of the options described in this Section 0 will be, when issued pursuant to the respective terms of such Target Preferred Stock or options, duly authorized, validly issued, fully paid and nonassessable. There are no other contracts, commitments or agreements relating to the voting, purchase or sale of Target’s capital stock (a) between or among Target and any of its stockholders; and (b) to Target’s knowledge, between or among any of Target’s stockholders.

                                   (b)        The authorized capital stock of each of the Subsidiaries and the issued and outstanding shares of such capital stock as of the date of this Agreement are reflected on Section 2.5(b) of the Target Disclosure Schedule. All such outstanding shares (i) are duly authorized, validly issued, fully paid and non-assessable, (ii) are free of any liens or encumbrances created by the Subsidiary and free of any liens or encumbrances created by or imposed upon Target and (iii) were not issued in violation of any preemptive rights or rights of first refusal created by statute, the certificate of incorporation or bylaws of any Subsidiary or any agreement to which Target or any Subsidiary is a party or by which it is bound.

                                   (c)         Shares and Stockholder Information. Section 2.5(c) of the Target Disclosure Schedule sets forth, as of the date hereof: (i) the number of shares of Target Capital Stock that each current stockholder of Target holds of record; and (ii) to the knowledge of Target, the address and state of residence of such stockholder.

                      2.6         Absence of Certain Changes. Between September 30, 2006 (the "Target Balance Sheet Date") and the date of this Agreement, Target and its Subsidiaries have conducted their business in the ordinary course consistent with past practice, and there has not occurred (a) any acquisition, sale or transfer of any material asset of Target or its Subsidiaries other than in the ordinary course of business; (b) any amendment to the certificate of incorporation or bylaws or equivalent organizational documents of Target or its Subsidiaries; (c) any material increase in, or material modification of, the compensation or benefits payable by Target or its Subsidiaries to any of their respective directors or executive officers; (d) any declaration, setting aside or payment of a dividend or other distribution with respect to shares of Target Capital Stock; or (e) any incurrence of indebtedness for borrowed money. Between the Target Balance Sheet Date and the date of this Agreement, there has not been any event or occurrence that has had, individually or in the aggregate, a Target Material Adverse Effect.

                      2.7         Absence of Undisclosed Liabilities. Neither Target nor any of its Subsidiaries has any material obligations or liabilities of any nature (matured or unmatured, fixed or contingent) other than: (a) those set forth or adequately provided for in the Target Balance Sheet; (b) those not required to be reflected in the liabilities column of a balance sheet prepared in accordance with GAAP; (c) those incurred in the ordinary course of business since the Target Balance Sheet Date; and (d) those incurred pursuant to or in connection with the execution, delivery or performance of this Agreement.

                      2.8         Litigation; Orders. There is no private or governmental action, suit, proceeding, arbitration or, to the knowledge of Target, investigation, pending before any Governmental Entity or threatened against Target or its Subsidiaries or against any of their respective officers or directors (in their capacities as such). There is no judgment, decree or order against Target or its Subsidiaries or against any of their respective directors or officers (in their capacities as such), that specifically names Target or its Subsidiaries or such directors or officers and (i) restricts in any material manner the use, transfer or licensing by Target or its Subsidiaries of any right or interest of Target or its Subsidiaries in any Material Target IP Right; or (ii) otherwise materially and adversely affects the conduct of the Current Target Business.

                      2.9         Intellectual Property.

                                   (d)        violate any order, writ, injunction or decree applicable to Acquiror or Merger Sub or any of their respective properties or assets, except for any violation that would

not reasonably be expected to have an Acquiror Material Adverse Effect;

                                   (b)        There is no judgment, decree or order against Acquiror or Merger Sub or, to the knowledge of Acquiror and Merger Sub, against any of their respective directors or officers (in their capacities as such) that specifically names Acquiror or its Subsidiaries or such directors or officers and that would reasonably be expected to result in an Acquiror Material Adverse Effect.

Until the effective date of the enrollment of the Continuing Employees in a particular Acquiror Employee Plan, Acquiror shall continue in effect without amendment or reduction in benefits the existing Target Employee Plan covering the same or similar benefits as would be covered by such Acquiror Employee Plan. Nothing in this Section 5.6 is intended to prevent Acquiror from terminating any of its benefit plans in a manner that does not affect the vested or other pre-existing rights of any Continuing Employee.

                                   (b)        Effective as of the day immediately preceding the Closing Date, Target and any ERISA Affiliate, shall have terminated any and all Target Employee Plans intended to include a Code Section 401(k) arrangement (each a "Target 401(k) Plan" and collectively, the "Target 401(k) Plans") (unless Acquiror shall have provided written notice to Target that such Target 401(k) Plans shall not be terminated).

                      5.7         FIRPTA Matters. At the Closing, Target shall deliver to Acquiror: (a) a statement conforming to the requirements of Section 1.897 - 2(h)(1)(i) of the United States Treasury Regulations; and (b) the notification to the Internal Revenue Service required under ▇▇▇▇▇▇▇ ▇.▇▇▇ - ▇(▇)(▇) ▇▇ ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇ Treasury Regulations.

                      5.8         Indemnification of Officers and Directors of Target and its Subsidiaries.

                                   (a)        From and after the Effective Time, Acquiror shall, and shall cause the Surviving Corporation and its Subsidiaries to, fulfill and honor in all respects the obligations of Target and its Subsidiaries pursuant to any indemnification provisions under the certificate of incorporation and bylaws of Target and the equivalent organization documents of its Subsidiaries as each is in effect on the date of this Agreement (the persons entitled to be indemnified pursuant to such provisions, and all other current and former directors and officers of Target and its Subsidiaries, being referred to collectively as the "Indemnified Parties").

                                   (b)        During the period ending on the sixth (6^th) anniversary of the Effective Time, Acquiror will, to the maximum extent provided by law (but subject to any limitations that are applicable to Target and its Subsidiaries under Applicable Laws and the provisions of the certificate of incorporation and bylaws of Target and the equivalent organizational documents of its Subsidiaries with respect to indemnification and exculpation from liability as in effect on the date of this Agreement) indemnify and hold harmless the Indemnified Parties against and from any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, to the extent such claim, action, suit, proceeding or investigation arises out of or pertains to (i) any action or omission or alleged action or omission in such Indemnified Party’s capacity as a director, officer or employee of Target or any of its Subsidiaries or (ii) any of the transactions contemplated by this Agreement (the "Indemnified Matters"); provided, however, that if, at any time prior to the sixth anniversary of the Effective Time, any Indemnified Party delivers to Acquiror a written notice asserting a claim for indemnification under this Section 5.8(b), then the claim asserted in such notice shall survive the sixth anniversary of the Effective Time until such time as such claim is fully and finally resolved. In the event of any such claim, action, suit, proceeding or investigation, (i) Acquiror will have the right to control the defense thereof after the Effective Time (it being understood that, by electing to control the defense thereof, Acquiror will be deemed to have waived any right to object to the Indemnified Parties’ entitlement to indemnification hereunder with respect thereto), (ii) any counsel retained by the Indemnified Parties with respect to the defense thereof for any period after the Effective Time must be reasonably satisfactory to Acquiror, and (iii) after the Effective Time, Acquiror will pay the reasonable fees and expenses of such counsel, promptly after statements therefor are received (provided that in the event of a final non-appealable judicial determination that any Indemnified Party is not entitled to indemnification hereunder, any amounts advanced on his or her behalf shall be remitted to the Surviving Corporation); provided, however, that neither Acquiror nor the Surviving Corporation, nor any Indemnified Party, will be liable for any settlement effected without its, his or her express written consent. The Indemnified Parties as a group may retain only one law firm (in addition to local counsel) to represent them with respect to any single action unless counsel for any Indemnified Party determines in good faith that, under applicable standards of professional conduct, a conflict exists or is reasonably likely to arise on any material issue between the positions of any two or more Indemnified Parties. Notwithstanding anything to the contrary contained in this Section 5.8(b) or elsewhere in this Agreement, Acquiror shall not settle or compromise or consent to the entry of any judgment or otherwise seek termination with respect to any claim, action, suit, proceeding or investigation for which indemnification may be sought under this Section 5.8 unless such settlement, compromise, consent or termination includes an unconditional release of all Indemnified Parties from all liability arising out of such claim, action, suit, proceeding or investigation.

                                   (c)        Acquiror and the Surviving Corporation jointly and severally agree to pay all expenses, including attorneys’ fees, that may be incurred by the Indemnified Parties in enforcing the indemnity and other obligations provided for in this Section 5.8.

                                   (d)        Through the sixth (6^th) anniversary of the Effective Time, Acquiror shall cause to be maintained in effect, for the benefit of the Indemnified Parties, directors’ and officers’ liability insurance coverage for all Indemnified Matters which is substantially equivalent to that provided under Target’s directors’ and officers’ liability insurance policy in effect as of the date of this Agreement; provided, however, that in no event shall Acquiror be required pursuant to this Section 5.8(d) to expend in any one year an amount in excess of 125% of the annual premium currently payable by Target with respect to such current policy, it being understood that if the annual premiums payable for such insurance coverage exceed such amount, Acquiror shall be obligated to obtain a policy with the greatest coverage available for a cost equal to such amount. . In lieu of such annual coverage, Acquiror may or may cause Target to purchase at the Effective Time a 6 year tail insurance policy complying with the coverage requirements set forth in the preceding sentence.

                                   (e)        This Section 5.8 shall survive the consummation of the Merger and the Effective Time, is intended to benefit and may be enforced by the Indemnified Parties, and shall be binding on all successors and assigns of Acquiror and the Surviving Corporation.

                      5.9         No Solicitation by Target; Board Recommendation; Fiduciary Exceptions.

                                   (a)        Subject to Section 5.9(b), prior to the receipt of the Required Stockholder Vote, Target shall not, nor shall it authorize or permit any of its Subsidiaries or any of its or their respective directors or officers, investment bankers, financial advisors, attorneys, accountants or other advisors, agents or representatives (each, a "Representative") (and Target shall use its reasonable efforts to cause its employees not), directly or indirectly, to (i) solicit, initiate or knowingly encourage, or take any other action designed to facilitate, any Takeover Proposal (as defined below) or (ii) enter into any discussions or negotiations with any third party regarding, or furnish to any person any information in connection with, any Takeover Proposal. Target shall, and shall cause its Subsidiaries and Representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any person conducted heretofore with respect to any Takeover Proposal (it being understood that if any executive officer or director of Target shall become aware that any of Target’s Representatives is violating this Section 5.9, Target shall instruct such person, and otherwise use reasonable efforts to cause such person, to cease such violation).

            The term "Takeover Proposal" means any proposal or offer from any person with respect to any transaction involving the acquisition or purchase (including in the case of Target IP Rights any material license or similar agreement other than one that is in the ordinary course (and in furtherance) of Target’s business) in one transaction or a series of related transactions, of assets (including Target IP Rights) or businesses that constitute 15% or more (on either a book value or fair market basis) of the revenues, net income or the assets of Target and its Subsidiaries, taken as a whole, or 15% or more of any class of equity securities of Target, any tender offer or exchange offer that if consummated would result in any person beneficially owning 15% or more of any class of equity securities of Target, or any merger, consolidation, business combination, recapitalization, liquidation, dissolution, joint venture, binding share exchange or similar transaction involving Target or any of its Subsidiaries pursuant to which any person or the stockholders of any person would own 15% or more of any class of equity securities of Target or of any resulting parent of Target or 15% or more (on either a book value or fair market basis) of the revenues, net income or the assets of Target and its Subsidiaries, taken as a whole, other than the transactions contemplated by this Agreement.

                                   (b)        Notwithstanding the provisions of clause (a) of this Section 5.9 or anything else in this Agreement, prior to receipt of the Required Stockholder Vote and in response to any bona fide written Takeover Proposal that the Board of Directors of Target determines in good faith (after consultation with a financial advisor of nationally recognized reputation) constitutes or would reasonably be expected to lead to a Superior Proposal, and which Takeover Proposal did not result from a breach of this Section 5.9 by Target, Target may, if its Board of Directors determines in good faith (after consultation with outside counsel) that failure to do so is reasonably likely to be inconsistent with its fiduciary duties to the stockholders of Target under Applicable Laws, (x) furnish information with respect to Target and its Subsidiaries to the person making such Takeover Proposal and such person’s representatives pursuant to a customary confidentiality agreement, provided that all such information has previously been provided to Acquiror or is provided to Acquiror prior to or substantially concurrent with the time it is provided to such person and (y) participate in discussions or negotiations with the person making such Takeover Proposal (and such person’s representatives) regarding such Takeover Proposal.

                                   (c)        The term "Superior Proposal" means any bona fide written proposal made by a third party that if consummated would result in such person (or its stockholders) owning, directly or indirectly, (A) all or substantially all of the shares of capital stock of Target then outstanding, or (B) all or substantially all of the assets of Target and its Subsidiaries, taken as a whole, in each case which the Board of Directors of Target determines in good faith (after consultation with a financial advisor of nationally recognized reputation) to be (x) more favorable to the stockholders of Target from a financial point of view than the transactions contemplated by this Agreement and (y) reasonably capable of being completed, taking into account all financial, legal, regulatory and other aspects of such proposal.

                                   (d)        Except as permitted by this Section 5.9(d), prior to the receipt of the Required Stockholder Vote, neither the Board of Directors of Target nor any committee thereof shall (i) (A) withdraw (or modify in a manner adverse to Acquiror), or publicly propose to withdraw (or modify in a manner adverse to Acquiror), the approval, recommendation or declaration of advisability by such Board of Directors or any such committee thereof of this Agreement, the Merger or the other transactions contemplated by this Agreement or (B) recommend, adopt or approve, or propose publicly to recommend, adopt or approve, any Takeover Proposal or (ii) allow, cause or authorize Target or any of its Subsidiaries to execute or enter into, any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other similar agreement providing for or contemplating the consummation of any Takeover Proposal (other than a confidentiality agreement as provided in Section 5.9(b)). Notwithstanding the foregoing or any other provision of this Agreement, prior to receipt of the Required Stockholder Vote, the Board of Directors of Target may take the actions set forth in clause (i)(A) above if such Board determines in good faith (after consultation with outside counsel) that the failure to do so would constitute a breach by the Board of Directors of Target of its fiduciary duties to the stockholders of Target under Applicable Laws.

                                   (e)        Target shall, promptly (and in no event later than 48 hours) after receipt of any Takeover Proposal or indication of interest that would reasonably be expected to lead to a Takeover Proposal, indication of interest or any request for nonpublic information relating thereto (which Takeover Proposal, indication of interest or request is received after the execution and delivery of this Agreement), advise Acquiror orally and in writing of such Takeover Proposal, indication of interest or request (including the identity of the person making or submitting such Takeover Proposal, indication of interest or request, and the material terms thereof). Target shall keep Acquiror reasonably informed with respect to the status of any such Takeover Proposal, indication of interest or request received and any modification or proposed modification thereto.

                      5.10        Notification of Certain Matters.

                                   (a)        Target shall use commercially reasonable efforts to give prompt notice to Acquiror of the occurrence, or failure to occur, of any event before the Closing which occurrence or failure causes (i) any representation or warranty of Target contained in this Agreement or any exhibit or schedule hereto to be untrue or inaccurate in any material respect or (ii) Target to be unable to comply with or satisfy by the Closing any material covenant, obligation, condition or agreement to be complied with or satisfied by it under this Agreement any exhibit or schedule hereto; provided, however, that such disclosure shall not be deemed to cure any breach of a representation, warranty, covenant, obligation, or agreement or to satisfy any condition. Target shall use commercially reasonable efforts to give prompt notice to Acquiror of any event or state of facts before the Closing that has or is reasonably likely to have a Target Material Adverse Effect. Any such notification by the Target shall not be deemed to amend the schedules hereto for purposes of determining whether the conditions set forth in Article 6 hereof have been satisfied and shall not be deemed to cure any breach of any representation or warranty or to limit the rights and remedies of the parties under this Agreement for any breach by the other parties of such representations and warranties.

                                   (b)        Acquiror shall give prompt notice to the Target of the occurrence, or failure to occur, of any event before the Closing which occurrence or failure causes Acquiror to be unable to comply with or satisfy by the Closing any material covenant, condition or agreement to be complied with or satisfied by it under this Agreement or any exhibit or schedule hereto; provided, however, that such disclosure shall not be deemed to cure any breach of a representation, warranty, covenant or agreement or to satisfy any condition.

                                   (c)        Not earlier than 10 and not less than 2 days before the date scheduled for Closing, Target shall correct and supplement in writing any information furnished on Schedules provided by Target that are incorrect or incomplete, and shall promptly furnish such corrected and supplemented information to Acquiror, so that all provided information shall be correct and complete at the time such updated information is so provided. Thereafter, prior to the Closing, the Target shall correct and supplement in writing any information furnished on its Schedules that is incorrect or incomplete. It is agreed that no such correction or supplement shall be deemed to create any presumption that such information constitutes or evidences the existence of a material change to, or a breach or violation by Target of, any provision of this Agreement. Any corrected and supplemental information shall not be deemed to amend the Schedules for purposes of determining whether the conditions set forth in Article 6 hereto have been satisfied and shall not be deemed to cure any breach of any representation or warranty or to limit the rights and remedies of Acquiror and Merger Sub under this Agreement for any breach by the Target such representations and warranties.

                      5.11        Payment of Transaction Expenses. Without limiting any obligation of the Surviving Corporation, Acquiror shall ensure that all Transaction Expenses and Severance Obligations not paid prior to the Closing shall be paid at or immediately after the Closing (it being understood that Acquiror and Target hereby acknowledge and agree that: (a) as a result of, and upon consummation of, the Merger (and without any other event occurring or circumstance existing), a "Constructive Termination" shall be deemed to have occurred pursuant to the change in control provisions in the offer letters from Target provided to those Target employees with offer letters as identified in Section 2.5(a) of the Target Disclosure Schedule; and (b) the payments that become due to such employees as a result of the deemed "Constructive Termination" referred to in this sentence shall be deemed to be "Severance Obligations" for purposes of this Agreement, including this Section 5.11), provided that the payment obligation of Acquiror, as to a particular employee, with respect thereto may be conditioned upon receipt by Acquiror of the release contemplated by such employee’s offer letter and an acknowledgement by such employee that such offer letter is no longer in force, except with respect to the obligation in the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ offer letter with respect to payment of amounts described in subclause (x) below. If the Milestone Event occurs, Acquiror shall pay, or shall cause Surviving Corporation to pay: (x) ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ the amount, net of applicable withholding taxes, owed based on the occurrence of such Milestone Event pursuant to the terms of ▇▇. ▇▇▇▇▇▇▇▇’▇ offer letter with Target; and (y) as promptly as practicable thereafter, but in no event later than forty-five days thereafter, Credit Suisse the amount, if any, due to Credit Suisse as set forth in the CFO Certificate.

                      5.12        Diligence and Reporting Regarding Ceftaroline Products. At all times prior to the occurrence of the Milestone Event, Acquiror shall comply with, and shall ensure that the Surviving Corporation shall comply with, all obligations under the Takeda Agreement regarding the development, seeking regulatory approval of and commercialization of products containing Ceftaroline. Further, after first approval of an NDA in the United States covering a product containing Ceftaroline, Acquiror shall, and shall insure that Surviving Corporation and any applicable other affiliates of Acquiror shall, promote all such products in the United States and take orders, make sales and fill orders for products containing Ceftaroline in the United States on a commercially reasonable basis consistent with Acquiror’s (or its affiliates’, as applicable) policies and practices with respect to its other products of similar market opportunity in the United States. Acquiror shall provide Stockholders’ Agent (after regulatory approval of any product containing Ceftaroline in the United States) with a written report every year that lists in reasonable detail all the promotion, marketing and sales efforts undertaken and/or conducted by or on behalf of Acquiror or Surviving Corporation (or their respective successors in interest) during the prior twelve months in the United States, the results of such sales efforts including a complete and accurate report of the actual Product Net Sales resulting in the United States in such twelve months period. The Former Holders are intended third party beneficiaries of the provisions of this Section 5.13, and the Stockholders’ Agent may enforce the Former Holders’ interests under this Section in case of breach hereof by Acquiror (and such enforcement by Stockholder’s Agent shall be the sole remedy for enforcing such Former Holders’ interests).

                      5.13        Audit Rights. Upon the written request of the Stockholders’ Agent and not more than once in each calendar year, Acquiror shall permit the Stockholders’ Agent and/or an independent certified public accounting firm of nationally recognized standing selected by the Stockholders’ Agent, at the expense of the Stockholders’ Agent (except as otherwise provided below), to have access during normal business hours to all of the records of Acquiror and the Surviving Corporation (and any affiliate or successor of interest of either as is applicable), for inspection, copying and analysis, as may be reasonably necessary to verify (a) the accuracy of the reports of Product Net Sales provided as required in Section 5.13 for any year or years ending not more than five years prior to the date of such request, and (b) the performance by Acquiror of its other obligations in Section 5.13. Such access and inspection shall be pursuant to reasonable and customary confidentiality agreements entered into between the inspecting party and the inspected party. If such accounting firm identifies a discrepancy in the amount of Product Net Sales made during the period audited, and such discrepancy indicates that the Milestone Event occurred at a time earlier than such reports would indicate, then (if not paid previously) the amounts of the Additional Merger Consideration owed to Former Holders under the terms of this Agreement based on such Milestone Event occurring shall be paid by Acquiror promptly after such payment obligation is identified, and if such discrepancy shows the Additional Merger Consideration should have been paid 90 or more days earlier than it was actually paid, then in addition all fees of such accounting firm in conducting such inspection shall be paid by Acquiror.

                      5.14        Right to Pursue [***] Opportunity if Acquiror Declines. Acquiror agrees that if Acquiror does not consent to Target entering into, prior to the Closing, the License Agreement with [***] (the "[***] Agreement") that is contemplated by the [***] Letter of Intent (as such term is defined in Target Disclosure Schedule), and if Acquiror does not subsequent to the Closing enter into the [***] Agreement, then at the request of Stockholders’ Agent, Acquiror will, and will cause Surviving Corporation to, discuss reasonably with Stockholder’s Agent (or appropriate institutional investors who are Former Holders) the reasonable terms under which certain interested Former Holders could pursue the business opportunity reflected in the [***] Letter of Intent by entering into a similar license agreement directly with [***]. Target acknowledges that it is important to Acquiror to obtain information promptly regarding the [***] Letter of Intent, the proposed [***] Agreement, and the technical information in Target’s possession regarding the [***] opportunity covered by the [***] Agreement, and as such Target shall request from [***] as soon as practicable the right to disclose such information to Acquiror, pursuant to a confidentiality agreement between Acquiror and [***], and shall use reasonable efforts to pursue obtaining the right to make such disclosure. Target shall also request [***].

                                   (c)         Limitations of Liability.

                                               (i)        Subject to Section 8.2(c)(iii), the right of Acquiror to be indemnified from the Escrow Fund pursuant to this Section 8 shall be the sole and exclusive remedy with respect to any inaccuracy of any representation or warranty of Target contained in, or any breach by Target of, this Agreement, or otherwise in connection with the transactions contemplated by this Agreement. Subject to Section 8.2(c)(iii), no current or former stockholder, optionholder, director, officer, employee, affiliate or advisor of Target shall have any personal or individual liability of any nature to Acquiror, the Surviving Corporation or any affiliate of Acquiror or the Surviving Corporation with respect to any inaccuracy of any representation or warranty contained in, or any breach of, this Agreement or the Target Closing Certificate, or otherwise in connection with the transactions contemplated by this Agreement. The parties acknowledge that (A) no current or former stockholder, director, officer, employee, affiliate or advisor of Target has made or is making any representations, warranties or commitments whatsoever regarding the subject matter of this Agreement, express or implied, (B) except as expressly provided in Section 2, Target has not made and is not making any representations, warranties or commitments whatsoever regarding the subject matter of this Agreement, express or implied, and (C) except as expressly provided in Section 2, Acquiror is not relying and has not relied on any representations, warranties or commitments whatsoever regarding the subject matter of this Agreement, express or implied.

                                               (ii)       Without limiting the effect of any other limitation contained in this Section 8, the indemnification provided for in this Section 8.2 shall not apply, and Acquiror shall not be entitled to exercise any indemnification rights under this Agreement: (A) with respect to any inaccuracy in any representation or warranty of Target set forth in Section 2 or the breach of any covenant by Target if the Damages relating to such inaccuracy or breach do not exceed $50,000; or (B) except to the extent that the aggregate amount of Damages relating to matters other than any claim for indemnification based on any inaccuracy in the CFO Certificate and against which Acquiror would otherwise be entitled to be indemnified under this Section 8.2 exceeds $1,500,000. If the aggregate amount of such Damages exceeds $1,500,000, then Acquiror shall, subject to the other limitations contained herein, be entitled to be indemnified from the Escrow Fund only against the portion of such Damages in excess of $1,500,000. Notwithstanding the foregoing, no claim for indemnification based on any inaccuracy in the CFO Certificate shall be subject to such $50,000 or $1,500,000 exclusion, and Acquiror shall be entitled to indemnity therefor on a "first dollar" basis.

                                               (iii)      Nothing in this Section 8.2(c) shall limit any remedy Acquiror may have against any person for fraud under applicable tort laws or with respect to the breach by such person of any contractual obligations (excluding obligations under this Agreement or the Escrow Agreement) to which such person is subject, including but not limited to any obligations not to compete with Target, not to disclose Target’s confidential information, or to assign to Target certain intellectual property rights.

                                   (d)         Defense of Third-Party Claims. Promptly after Acquiror obtains knowledge of any actual or possible claim, demand, suit, action, arbitration, investigation, inquiry or proceeding that has been or may be brought or asserted by a third party against Acquiror or any of Acquiror’s Subsidiaries or other affiliates and that may be subject to indemnification hereunder (a "Third-Party Claim"), Acquiror shall promptly give notice of such Third-Party Claim to the Stockholders’ Agent, stating the nature and basis of such Third-Party Claim and the dollar amount of such Third-Party Claim, to the extent known. The Stockholders’ Agent shall have the right at its election, at any time, to defend any Third-Party Claim if the sole remedy sought thereby is for money damages in an amount which is not more than 25% of the amount which is then remaining in the Escrow Fund and available to pay such damages (a "Qualifying Claim"). Any such election shall constitute an irrevocable acknowledgement by the Stockholders’ Agent and to conclusively establish that the Aquiror and the Merger Sub are entitled to be indemnified hereunder in respect of such Third Party Claim, and if such election is exercised, : (i) Stockholders’ Agent shall diligently and in good faith defend such Third-Party Claim; (ii) the attorneys’ fees of counsel reasonably acceptable to Acquiror (approval of such counsel not to be unreasonably withheld), other professionals’ and experts’ fees and court or arbitration costs incurred by the Stockholders’ Agent in connection with defending such Third-Party Claim shall be payable from the Escrow Fund with the approval of the Acquiror which approval will not be unreasonably withheld; (iii)  Acquiror shall be entitled to monitor such defense at its expense; (iv) Acquiror shall make available to the Stockholders’ Agent all books, records and other documents and materials that are under the direct or indirect control of Acquiror or any of its Subsidiaries or other affiliates and that the Stockholders’ Agent considers necessary or desirable for the defense of such Third-Party Claim; (v) Acquiror shall execute such documents and take such other actions as the Stockholders’ Agent may reasonably request for the purpose of facilitating the defense of, or any settlement, compromise or adjustment relating to, such Third-Party Claim; (vi) Acquiror shall otherwise fully cooperate as reasonably requested by the Stockholders’ Agent in the defense of such Third-Party Claim; (vii) Acquiror shall not admit any liability with respect to such Third-Party Claim; and (viii) the Stockholders’ Agent shall not enter into any settlement agreement providing for the settlement of such Third-Party Claim without the prior written consent of Acquiror (which consent shall not be unreasonably withheld) if such settlement agreement imposes on Acquiror or any of its Subsidiaries or other affiliates any obligation, other than an obligation to pay monetary damages in an amount less than the aggregate cash amount remaining in the Escrow Fund and available to pay such damages. Acquiror shall diligently defend (i) any Qualifying Claim which the Stockholder’s Agent elects not to defend as provided herein , and any other Third-Party Claim but (ii) Acquiror shall have no right to seek indemnification under this Section 8 in respect of any settlement of any such Claim entered into without the prior written consent of the Stockholders’ Agent, which consent shall not be unreasonably withheld, and (iii) Stockholder’s Agent shall be entitled to monitor such defense at its expense (any such expense to be paid out of the Escrow Fund subject to the Acquiror’s approval which approval will not be unreasonably withheld or delayed).

                      8.3         Stockholders’ Agent.

                                   (a)        Notwithstanding any other provision of this Agreement, at the Effective Time, Acquiror shall deposit, or shall cause to be deposited, with respect to each share of Target Capital Stock held by the Non-Dissenting Former Stockholders immediately prior to the Effective Time, an amount equal to the Stockholders’ Agent Expense Contribution Amount, and with respect to each Target Option outstanding immediately prior to the Effective Time, an amount equal to the Stockholders’ Agent Expense Contribution Amount times the number of shares of Target Capital Stock that are subject to such Target Option, by wire transfer of immediately available funds in an account designated by the Stockholders’ Agent to be used for payment of any Stockholders’ Agent Expenses (the "Stockholders’ Agent Expense Account"). The amount that is deposited by Acquiror into the Stockholders’ Agent Expense Account pursuant to this Section 8.3(a) with respect to each share of Target Capital Stock and each Target Option shall reduce the amount that, but for the provisions of this Section 8.4, the holder of such share of Target Capital Stock would have otherwise been entitled to receive at the Effective Time in respect of such share of Target Capital Stock pursuant to Section 1.6 hereof and the holder of such Target Option would have otherwise been entitled to receive at the Effective Time in respect of such Target Option pursuant to Section 1.11 hereof.

                                   (b)        The Stockholders’ Agent may, from time to time, withdraw amounts from the Stockholders’ Agent Expense Account for the payment of Stockholders’ Agent Expenses. Upon termination of the Escrow Agreement, if there shall be any amount on deposit in the Stockholders’ Agent Expense Account, the Stockholders’ Agent shall cause such amount to be distributed to the Former Holders ratably based on their Pro Rata Portion thereof.

                                   (c)        By virtue of the adoption of this Agreement by Target’s stockholders, and without further action of any Target stockholder or option holder, each Former Holder shall be deemed to have irrevocably constituted and appointed ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ and ▇▇▇▇▇▇ ▇▇▇▇▇ (and by execution of this Agreement each of them hereby accepts such appointment) as agent and attorney-in-fact ("Stockholders’ Agent") for and on behalf of the Former Holders, with full power of substitution, to act in the name, place and stead of each Former Holder with respect to this Section 8 and the Escrow Agreement and the taking by the Stockholders’ Agent of any and all actions and the making of any decisions required or permitted to be taken by the Stockholders’ Agent under this Agreement or the Escrow Agreement, including the exercise of the power to: (i) give and receive notices and communications under this Section 8 or the Escrow Agreement; (ii) authorize delivery to Acquiror of cash from the Escrow Fund in satisfaction of claims for indemnification made by Acquiror under this Section 8; (iii) object to claims for indemnification made by Acquiror under this Section 8; (iv) agree to, negotiate, enter into settlements and compromises of, and comply with orders of courts with respect to claims for indemnification made by Acquiror under this Section 8; and (v) take all actions necessary or appropriate in the good faith judgment of the Stockholders’ Agent for the accomplishment of the foregoing. The power of attorney granted in this Section 8.3 is coupled with an interest and is irrevocable, may be delegated by the Stockholders’ Agent and shall survive the death or incapacity of any Former Holder. The identity of the Stockholders’ Agent and the terms of the agency may be changed, and a successor Stockholders’ Agent may be appointed, from time to time (including in the event of the death, disability or other incapacity of the Stockholders’ Agent) by Former Holders whose aggregate Pro Rata Portions exceed 50%, and any such successor shall succeed the Stockholders’ Agent as Stockholders’ Agent hereunder. No bond shall be required of the Stockholders’ Agent, and the Stockholders’ Agent shall receive no compensation for his services.

                                   (d)        The Stockholders’ Agent shall not be liable to any Former Holder for any liability, loss, damage, suffered by such Former Stockholder while acting in good faith and arising out of or in connection with the acceptance or administration of his duties hereunder (it being understood that any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith).

                                   (e)        From and after the Effective Time, Acquiror shall cause the Surviving Corporation to provide the Stockholders’ Agent with access to information about the Surviving Corporation and the assistance of the officers and employees of Acquiror and the Surviving Corporation, in each case to the extent reasonably necessary to enable the Stockholder’s Agent to perform his duties and exercise his rights under this Agreement, provided that the Stockholders’ Agent shall treat confidentially any nonpublic information he receives from Acquiror regarding the Surviving Corporation.

                                   (f)        The Stockholders’ Agent shall be entitled to no compensation for his service in such capacity.

                      8.4         Actions of the Stockholders’ Agent. From and after the Effective Time, a decision, act, consent or instruction of the Stockholders’ Agent shall constitute a decision of all Former Stockholders and shall be final, binding and conclusive upon each Former Stockholder, and the Escrow Agent and Acquiror may rely upon any decision, act, consent or instruction of the Stockholders’ Agent as being the decision, act, consent or instruction of each Former Stockholder. Acquiror and Surviving Corporation are hereby relieved from any liability to any person for any acts done by Stockholders’ Agent and any acts done by Acquiror or Surviving Corporation in accordance with any such decision, act, consent or instruction of the Stockholders’ Agent. For all purposes of this Agreement involving Stockholders’ Agent, any document executed or purported to be executed by either ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ or ▇▇▇▇▇▇ ▇▇▇▇▇ (or by both of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ and ▇▇▇▇▇▇ ▇▇▇▇▇) in their capacity as Stockholders’ Agent shall constitute a document executed by, and action authorized by, the Stockholders’ Agent.

                      9.2         Target Disclosure Schedule. Target Disclosure Schedule will be arranged to correspond to the representations and warranties in Section 2 of this Agreement, or as applicable to the relevant other Section of this Agreement, and the disclosure in any portion of Target Disclosure Schedule shall qualify the corresponding provision in Section 2 and any other provision of Section 2 to which it is reasonably apparent on its face that such disclosure relates.

                      9.3         Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement, and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart.

                      9.4         Entire Agreement; Nonassignability; Parties in Interest. This Agreement and the documents and instruments delivered pursuant hereto, including the exhibits hereto, Target Disclosure Schedule and the other schedules hereto: (a) together constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof, except for the Confidentiality Agreement, which shall continue in full force and effect in accordance with their terms and shall survive any termination of this Agreement; (b) are not intended to confer upon any other person any rights or remedies hereunder, except as provided in the final sentence of this Section 9.4; and (c) shall not be assigned by Acquiror or Merger Sub, on the one hand, or by Target, on the other hand (by operation of law or otherwise), without the written consent of each of the parties hereto. Notwithstanding anything to the contrary contained in this Agreement (but without limiting any of the rights of the Stockholders’ Agent hereunder), if the Merger is consummated, (i) the Former Holders shall be third party beneficiaries of the provisions set forth in Section 1 and Section 5.13 and (ii) the Indemnified Parties shall be third party beneficiaries of the provisions set forth in Section 5.8.

                      9.5         Severability. In the event that any provision of this Agreement, or the application thereof becomes, or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement, and the application of such provision to other persons or circumstances other than those as to which it is determined to be illegal, void or unenforceable, will not be impaired or otherwise affected and will continue in full force and effect and be enforceable to the fullest extent permitted by law.

                      9.6         Remedies Cumulative. Except as otherwise provided in this Agreement, 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.

                      9.7         Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Delaware applicable to parties residing in the State of Delaware, without regard to applicable principles of conflicts of law. Each of the parties irrevocably consents to the exclusive jurisdiction of the Delaware Court of Chancery or any federal court sitting in Delaware in connection with any action or proceeding based upon or arising out of this Agreement or the transactions contemplated hereby that is instituted by any other party or third party beneficiary of this Agreement, and agrees that process in any such action or proceeding may be served upon it in any manner authorized by the laws of the State of Delaware and waives and covenants not to assert or plead any objection which it might otherwise have to such jurisdiction and such process. Each of the parties irrevocably waives the right to trial by jury in connection with any matter based upon or arising out of this Agreement or the transactions contemplated hereby.

                      9.8         Rules of Construction.

                                   (a)        The parties hereto agree that they have been represented by counsel during the negotiation, preparation and execution of this Agreement and, therefore, waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

                                   (b)        For purposes of this Agreement, whenever the context requires: the singular number shall include the plural, and vice versa; the masculine gender shall include the feminine and neuter genders; the feminine gender shall include the masculine and neuter genders; and the neuter gender shall include the masculine and feminine genders.

                                   (c)        As used in this Agreement, (i) the words "include" and "including," and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words "without limitation" and (ii) the words "hereby," "herein," "hereunder" and "hereto" shall be deemed to refer to this Agreement in its entirety and not to any specific section of this Agreement.

                                   (d)        Except as otherwise indicated, all references in this Agreement to "Sections," "Schedules" and "Exhibits" are intended to refer to Sections of this Agreement and Schedules and Exhibits to this Agreement.

                      9.9         Time is of the Essence; Enforcement. Time is of the essence of this Agreement. Each of the parties hereto agrees that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. 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.

                      9.10        Amendment; Waiver. At or prior to the Effective Time, this Agreement may be amended by the parties hereto; provided, however, that after the Required Stockholder Vote has been obtained, there shall be made no amendment that by law requires further approval of the stockholders of Target without such approval having been obtained. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto. Any waiver of any of the terms or conditions of this Agreement must be in writing and must be duly executed by or on behalf of the party to be charged with such waiver. Except as expressly set forth in this Agreement, the failure of a party to exercise any of its rights hereunder or to insist upon strict adherence to any term or condition hereof on any one occasion shall not be construed as a waiver or deprive that party of the right thereafter to insist upon strict adherence to the terms and conditions of this Agreement at a later date. Further, no waiver of any of the terms and conditions of this Agreement shall be deemed to or shall constitute a waiver of any other term of condition hereof (whether or not similar).
