(this "Agreement"), among PERBIO SCIENCE AB, a Swedish corporation ("Parent"), EWOK ACQUISITION CORP., a Massachusetts corporation and a wholly owned subsidiary of Parent ("Sub"), and ENDOGEN, INC., a Massachusetts corporation (the "Company"). WHEREAS the respective Boards of Directors of Parent, Sub and the Company have approved the acquisition of the Company by Parent on the terms and subject to the conditions set forth in this Agreement and believe that the Merger (as defined below), is advisable and in the best interests of their respective Stockholders; WHEREAS, in furtherance of such acquisition, pursuant to this Agreement, Parent has agreed to cause Sub to make a tender offer to purchase all the outstanding shares of Common Stock, par value $.01 per share, of the Company (the "Company Common Stock"; all the outstanding shares of Company Common Stock being hereinafter collectively referred to as the "Shares") at a purchase price of $3.75 per Share in U.S. dollars (the "Offer Price"), net to the seller in cash, without interest thereon, upon the terms and subject to the conditions set forth in this Agreement (as it may be amended from time to time as permitted under this Agreement, the "Offer"); and the Board of Directors of the Company has adopted resolutions approving the Offer and the Merger recommending that the Company's stockholders accept the Offer and approving the acquisition of Shares by Sub pursuant to the Offer and the Stockholder Agreement (as defined herein); WHEREAS the respective Boards of Directors of Parent, Sub and the Company have each approved the merger of Sub into the Company (the "Merger"), upon the terms and subject to the conditions set forth in this Agreement, whereby each Share, other than Shares owned directly or indirectly by Parent or the Company and Dissenting Shares (as defined in Section 3.1(d)), will be converted into the right to receive the price per share paid in the Offer; WHEREAS, concurrently with the execution of this Agreement and as an inducement to Parent to enter into this Agreement, Parent, Sub and certain stockholders of the Company including all of the Company's executive officers and directors are entering into a Stockholder Agreement (the "Stockholder Agreement") pursuant to which such stockholders have, among other things, agreed to sell or tender all of such stockholders' Shares to Sub at a cash price per Share equal to the Offer Price, upon the terms and subject to the conditions set forth in the Stockholder Agreement WHEREAS, concurrently with the execution of this Agreement and as an inducement to Parent to enter into this Agreement, Sub and certain employees of the Company are executing and delivering Employment Agreements (the "Employment Agreements") copies of which have been delivered to the Company; and WHEREAS Parent, Sub and the Company desire to make certain representations, warranties, covenants and agreements in connection with the Offer and the Merger and also to prescribe various conditions to the Offer and the Merger. NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, Parent, Sub and the Company hereby agree as follows: ARTICLE I THE OFFER 1.1 The Offer. (a) Subject to the terms and conditions set forth in this Agreement, within five (5) business days after the date of the public announcement, which shall occur on the date hereof or the following day, by Parent and the Company of this Agreement, Sub shall, and Parent shall cause Sub to, commence (within the meaning of Rule 14d-2 under the Exchange Act (as hereinafter defined)) the Offer, which shall expire at midnight, New York City time, on the date that is twenty (20) business days after the date the Offer is commenced (the initial "Expiration Date," and any expiration time and date established pursuant to an authorized extension of the Offer as so extended, also an "Expiration Date"). The obligation of Sub to, and of Parent to cause Sub to, commence the Offer, conduct and consummate the Offer as soon as practicable after the date hereof and accept for payment, and pay for, any Shares tendered and not withdrawn pursuant to the Offer shall be subject only to the conditions set forth in Exhibit A (the "Offer Conditions") (any of which may be waived in whole or in part by Sub in its sole discretion, provided that, without the express written consent of the Company, Sub may not waive the Minimum Condition (as defined in Exhibit A)). Sub expressly reserves the right, subject to compliance with the Exchange Act, to modify the terms of the Offer, except that, without the express written consent of the Company, Sub shall not (i) reduce the number of Shares subject to the Offer, (ii) reduce the Offer Price, (iii) add to or modify the Offer Conditions, including the Minimum Condition, (iv) except as provided in the next sentence, extend the Offer, if all of the Offer Conditions are satisfied or waived, (v) change the form of consideration payable in the Offer or (vi) amend or alter any term of the Offer in any manner materially adverse to the holders of the Shares, provided, however, that nothing contained herein shall prohibit Sub, in its sole discretion without the consent of the Company, from waiving satisfaction of any condition to the Offer other than the Minimum Condition. Notwithstanding the foregoing, Sub may, without the consent of the Company, (A) extend the Offer (each individual extension not to exceed five (5) business days after the previously scheduled Expiration Date), if at the then scheduled Expiration Date of the Offer any of the Offer Conditions shall not be satisfied or waived, until such time as such conditions are satisfied or waived, (B) extend the Offer for any period required by any rule, regulation, interpretation or position of the Securities and Exchange Commission (the "SEC") or the staff thereof applicable to the Offer, and (C) extend the Offer on up to two occasions in each case for period of not more than five (5) business days beyond the latest Expiration Date if on 2 such Expiration Date there shall have been tendered more than the number of Shares sufficient to satisfy the Minimum Condition but less than 90% of the Shares; provided, Parent agrees to permanently waive the Offer Conditions. Subject to the terms and conditions of the Offer and this Section 1.1(a), Sub shall, and Parent shall cause Sub to, accept for payment, and pay for, all Shares validly tendered and not withdrawn pursuant to the Offer that Sub becomes obligated to accept for payment, and pay for, pursuant to the Offer as soon as practicable after the expiration of the Offer. (b) On the date of commencement of the Offer, Parent and Sub shall file with the SEC a Tender Offer Statement on Schedule 14D-1 (the "Schedule 14D-1") with respect to the Offer, which shall contain an offer to purchase and a related letter of transmittal (such Schedule 14D-1 and the documents included therein pursuant to which the Offer will be made, together with any supplements or amendments thereto, the "Offer Documents"). Parent and Sub agree that the Offer Documents shall comply as to form in all material respects with the Securities Exchange Act of 1934, as amended and the rules and regulations promulgated thereunder (the "Exchange Act"), and the Offer Documents, on the date first published, sent or given to the Company's stockholders, shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, except that no representation or warranty is made by Parent or Sub with respect to written information supplied by or on behalf of the Company or any of its stockholders for inclusion or incorporation by reference in the Offer Documents. Parent, Sub and the Company each agrees promptly to correct any written information provided by it for use in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect, and Parent and Sub further agree to take all steps necessary to cause the Schedule 14D-1 as so corrected to be filed with the SEC and the other Offer Documents as so corrected to be disseminated to holders of Shares, in each case as and to the extent required by applicable laws. The Company and its counsel shall be given reasonable opportunity to review and comment upon the Offer Documents prior to their filing with the SEC or dissemination to the stockholders of the Company. Parent and Sub agree to provide the Company and its counsel any comments Parent, Sub or their counsel may receive from the SEC or its staff with respect to the Offer Documents promptly after the receipt of such comments. (c) Parent shall provide or cause to be provided to Sub on a timely basis the funds sufficient to accept for payment, and pay for, any and all Shares that Sub becomes obligated to accept for payment, and pay for, pursuant to the Offer. 1.2. Company Actions. (a) The Company hereby approves of and consents to the Offer and represents that the Board of Directors of the Company, at a meeting duly called and held, duly adopted resolutions approving this Agreement and the Stockholder Agreement, the Offer and the Merger, determining that the terms of the Offer and the Merger are fair to, and in the best interests of, the Company and its stockholders and recommending that the Company's stockholders accept the Offer, tender their Shares pursuant to the Offer and approve and adopt the Merger and this 3 Agreement (if required); provided, however, that such recommendation and approval may be withdrawn, modified or amended to the extent that the Board of Directors of the Company determines in good faith, after consultation with its outside legal counsel, that failure to take such action could reasonably be expected to result in a breach of the Board of Directors' fiduciary obligations under applicable law and the Company terminates this Agreement pursuant to Section 9.1(d). The Company represents that its Board of Directors has received the opinion of Adams, Harkness & Hill, Inc. ("AH&H") dated the date of this Agreement to the effect that, as of such date and based upon and subject to the matters set forth therein, the cash consideration to be received by the holders of Shares (other than Parent and its Affiliates) pursuant to the Offer and the Merger is fair from a financial point of view to such holders, and a complete and correct signed copy of such opinion will promptly be delivered by the Company to Parent. The Company has been authorized by AH&H to permit the inclusion of such opinion (or a reference thereto) in the Schedule 14D-1, the Schedule 14D-9 (as hereinafter defined) and the Proxy Statement (as hereinafter defined). (b) On the date the Offer Documents are filed with the SEC, or promptly thereafter, the Company shall file with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the Offer (such Schedule 14D-9, as amended from time to time, the "Schedule 14D-9") containing the recommendation described in paragraph (a) and shall mail the Schedule 14D-9 to the stockholders of the Company to the extent required by Rule 14d-9 promulgated under the Exchange Act and any other applicable federal securities laws; provided, however, that if the Board of Directors of the Company determines in good faith, after consultation with its outside legal counsel, that the amendment or withdrawal of such recommendation is likely to be required in order for its members to comply with their fiduciary duties under applicable law and the Company terminates this Agreement pursuant to Section 9.1(d), then any such amendment or withdrawal, and any related amendment of the Schedule 14D-9, shall not constitute a breach of this Agreement. The Schedule 14D-9 shall comply as to form in all material respects with the requirements of the Exchange Act and the rules and regulations promulgated thereunder and, on the date filed with the SEC and on the date first published, sent or given to the Company's stockholders, shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, except that no representation or warranty is made by the Company with respect to written information supplied by or on behalf of Parent or Sub for inclusion in the Schedule 14D-9. Each of the Company, Parent and Sub agrees promptly to correct any written information provided by it for use in the Schedule 14D-9 if and to the extent that such information shall have become false or misleading in any material respect, and the Company further agrees to take all steps necessary to amend or supplement the Schedule 14D-9 and to cause the Schedule 14D-9 as so amended or supplemented to be filed with the SEC and disseminated to the Company's stockholders, in each case as and to the extent required by applicable laws. Parent and its counsel shall be given reasonable opportunity to review and comment upon the Schedule 14D-9 prior to its filing with the SEC or dissemination to stockholders of the Company. The Company agrees to provide Parent and its counsel any comments the Company or its counsel may receive from the SEC or its staff with respect to the Schedule 14D-9 promptly after the receipt of such comments. 4 (c) In connection with the Offer and the Merger, the Company shall cause its transfer agent to furnish Sub promptly with mailing labels containing the names and addresses of the record holders of Shares as of a recent date and of those persons becoming record holders subsequent to such date, together with copies of all lists of stockholders, security position listings and computer files and all other information in the Company's possession or control regarding the beneficial owners of Shares, and shall furnish to Sub such information and assistance (including updated lists of stockholders, security position listings and computer files) as Parent may reasonably request in communicating the Offer to the Company's stockholders. Subject to the requirements of applicable law, and except for such steps as are necessary to disseminate the Offer Documents and any other documents necessary to consummate the Merger, Parent and Sub and their agents shall hold in confidence the information contained in any such labels, listings and files, will use such information only in connection with the Offer and the Merger and, if this Agreement shall be terminated, will, upon request, promptly deliver, and will use their best efforts to cause their agents promptly to deliver, to the Company all copies of such information then in their possession or control. ARTICLE II THE MERGER 2.1. The Merger.

The Merger shall become effective at such time as the Articles of Merger filed with the Secretary of the Commonwealth of the Commonwealth of Massachusetts are duly accepted for record with the Massachusetts Secretary of the Commonwealth (the time the Merger becomes effective being hereinafter referred to as the "Effective Time"). 2.4. Effects of the Merger. The Merger shall have the effects set forth in the MBCL. The purpose of the Surviving Corporation shall be to engage in the business of research related to, and the development of proprietary products for, laboratory and clinical use and to engage in any other business activity now or hereafter permitted by the Commonwealth of Massachusetts to a corporation organized under Chapter 156B of the MBCL. 2.5. Articles of Organization and By-laws. (a) The Articles of Organization of the Company (the "Articles of Organization"), as in effect immediately prior to the Effective Time, shall be the articles of organization of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable law; provided, that Parent shall be entitled, in its sole discretion, to amend and/or restate the Articles of Organization simultaneously with the Effective Time. (b) The by-laws of Sub (the "By-laws") as in effect immediately prior to the Effective Time shall be the by-laws of the Surviving Corporation, until thereafter changed or amended as provided therein or by applicable law. 2.6. Directors. The directors of Sub immediately prior to the Effective Time shall be the directors of the Surviving Corporation, until the earlier of their death, resignation or removal or until their respective successors are duly elected and qualified, as the case may be. 2.7. Officers. The officers of Sub and such other persons as designated by Parent immediately prior to the Effective Time shall be the officers of the Surviving Corporation, until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be. 6 ARTICLE III EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES 3.1. Effect on 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 or any shares of capital stock of Sub: (a) Capital Stock of Sub. Each issued and outstanding share of capital stock of Sub shall be converted into and become one fully paid and nonassessable share of Common Stock, par value $.01 per share, of the Surviving Corporation. (b) Cancellation of Treasury Stock and Parent Owned Stock. Each share of the Common Stock of the Company that is owned by the Company and each Share that is owned by Parent or any other direct or indirect wholly owned subsidiary of Parent shall automatically be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor. (c) Conversion of Company Common Stock. Subject to Section 3.1(d), each issued and outstanding Share (other than shares to be canceled in accordance with Section 3.1(b)) shall be converted into the right to receive from the Surviving Corporation in cash, without interest, the price actually paid in the Offer (the "Merger Consideration"). As of the Effective Time, all such Shares shall no longer be outstanding and shall be canceled and retired automatically and shall cease to exist, and each holder of a certificate representing any such Shares shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration, without interest. (d) Shares of Dissenting Stockholders. Notwithstanding anything in this Agreement to the contrary, any issued and outstanding Shares held by a person (a "Dissenting Stockholder") who has neither voted in favor of the Merger nor consented in writing thereto and otherwise complies with all the applicable provisions of the MBCL concerning the right of holders of Company Common Stock to dissent from the Merger and require appraisal of their Shares ("Dissenting Shares") shall not be converted as described in Section 3.1(c) but shall become the right to receive such consideration as may be determined to be due to such Dissenting Stockholder pursuant to the laws of the Commonwealth of Massachusetts. If, after the Effective Time, such Dissenting Stockholder withdraws his demand for appraisal or fails to perfect or otherwise loses his right of appraisal, in any case pursuant to the MBCL, his Shares shall be deemed to be converted as of the Effective Time into the right to receive the Merger Consideration. The Company shall give Parent (i) prompt notice of any demands for appraisal of Shares received by the Company and (ii) if and after Sub shall have accepted for payment Shares pursuant to and subject to the conditions of the Offer (including the Minimum Condition), the opportunity to participate in and direct all negotiations and proceedings with respect to any such demands. The Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle, offer to settle or otherwise negotiate, any such demands. 7 3.2. Exchange of Certificates. (a) Paying Agent. Prior to the Effective Time, Parent shall designate a commercial bank or trust company to act as paying agent in the Merger (the "Paying Agent"). As of the Effective Time, Parent shall cause the Surviving Corporation to deposit with the Paying Agent in separate trust for holders of the Certificates (as hereinafter defined) cash in U.S. dollars in an amount sufficient for the payment of the aggregate Merger Consideration for the shares converted pursuant to Section 3.1(c) (it being understood that any and all interest earned on funds made available to the Paying Agent pursuant to this Agreement shall be turned over to Parent). (b) Exchange Procedure. As soon as reasonably practicable after the Effective Time, the Paying Agent shall mail to each holder of record of a certificate or certificates that immediately prior to the Effective Time represented Shares (the "Certificates"), (i) a letter of transmittal (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 Paying Agent and shall be in a form and have such other provisions as Parent may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Upon surrender of a Certificate for cancellation to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Paying Agent, the holder of such Certificate shall be entitled to receive in exchange therefor, and the Paying Agent shall pay pursuant to irrevocable instructions given by Sub or Parent, the amount of cash into which the Shares theretofore represented by such Certificate shall have been converted pursuant to Section 3.1, and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Shares that is not registered in the transfer records of the Company, payment may be made to a person other than the person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment shall pay any transfer or other taxes required by reason of the payment to a person other than the registered holder of such Certificate or establish to the satisfaction of the Surviving Corporation that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the amount of cash, without interest, into which the Shares theretofore represented by such Certificate shall have been converted pursuant to Section 3.1. No interest will be paid or will accrue on the cash payable upon the surrender of any Certificate. (c) No Further Ownership Rights in Company Common Stock. All cash paid upon the surrender of Certificates in accordance with the terms of this Article III shall be deemed to have been paid in full satisfaction of all rights pertaining to the Shares formerly represented by such Certificates. At the Effective Time, the stock transfer books of the Company shall be closed, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Paying Agent for any reason except notation thereon that a stockholder has elected to exercise his right 8 to appraisal pursuant to the MBCL they shall be canceled and exchanged as provided in this Article III. (d) No Liability. Any funds deposited with the Paying Agent that remain unclaimed by the former stockholders of the Company for three (3) months after the Effective Time shall be paid to the Surviving Corporation upon demand, and any former stockholders of the Company who have not theretofore complied with the instructions for exchanging their Certificates provided herein shall thereafter look only to the Surviving Corporation for payment of their claims for the Merger Consideration set forth in Section 3.1 hereof for each Share held by such stockholder, without any interest thereon. None of Parent, Sub, the Company or the Paying Agent shall be liable to any person in respect of any cash delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificates shall not have been surrendered prior to seven years after the Effective Time (or immediately prior to such earlier date on which any payment pursuant to this Article III would otherwise escheat to or become the property of any Governmental Entity (as defined in Section 4.5)), the cash payment 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 interests of any person previously entitled thereto. ARTICLE IV REPRESENTATIONS AND WARRANTIES OF THE COMPANY The Company represents and warrants to Parent and Sub as follows: 4.1. Organization.

Without limiting the foregoing, it is understood that any violation of the restrictions set forth in the preceding sentence by any director, officer or employee of the Company or any Subsidiary or any investment banker, financial advisor, attorney, accountant or other representative of the Company, acting on behalf of the Company, shall be deemed to be a breach of this Section 6.2(a) by the Company.

Notwithstanding the preceding sentence, if the Company's Board determines in its good faith judgment, after taking into consideration the advice of its outside legal counsel, that it is required by reason of their fiduciary duties under applicable law, the Company's Board of Directors may subject to Section 9.1(d): (A) withdraw its recommendation of the Offer or the Merger and the other transactions contemplated hereby, or (B) approve or recommend or cause the Company to enter into an agreement with respect to a Superior Proposal; provided, however, that the Company concurrently terminates this Agreement pursuant to Section 9.1(d).

(d) Nothing contained in this Section 6.2 shall prohibit the Company from at any time taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a) promulgated under the Exchange Act or from making any disclosure to the Company's stockholders, in each case with respect to any Third Party Proposal, if (i) in the good faith judgment of the Board of Directors of the Company, after consultation with its outside counsel, such disclosure is required by reason of the Board of Directors' fiduciary duties under applicable law and (ii) the Company shall have provided Parent and Sub with reasonable advance notice of its position and proposed disclosure under the circumstances; provided, however, that neither the Company nor its Board of Directors nor any committee thereof shall, except as permitted by Section 6.2(b), withdraw or modify, or propose to withdraw or modify, its position with respect to the Offer, the Merger or this Agreement or approve or recommend, or propose to approve or recommend, an Alternative Transaction. 28 6.3 Certain Tax Matters.

(b) The Company shall use its best efforts to obtain from all its employees who exercised a Company Stock Option or Warrants for which the proper amount of payroll or employment taxes were not withheld by the Company upon the exercise of such Company Stock Option or Warrant, a properly executed IRS Form 4669 from each such employee, in which such employee certifies that such employee has paid in full all taxes applicable to the compensation income attributable to such exercise. 6.4 Other Actions. The Company shall not, and shall cause each Subsidiary not to, take or omit to take any action, the taking or omission of which would reasonably be expected to result in (a) any of the representations and warranties of the Company set forth in this Agreement becoming untrue or inaccurate in any material respect or (b) any of the Offer Conditions not being satisfied (subject to the Company's right to take actions specifically permitted by Section 6.2 or 9.1). For purposes of this Section 6.4, "in any material respect" shall mean that claims, demands, damages, liabilities and losses arising out of such untruth or inaccuracy will actually or may reasonably be expected to result in damages, losses, costs and expenses (including reasonable attorney's fees and court costs) (collectively, "Losses") suffered or incurred by the Company, Parent or Sub, when taken as a whole, in excess of $300,000. 6.5 Advice of Changes; Filings. The Company shall confer with Parent on a regular and frequent basis as reasonably requested by Parent, report on operational matters and promptly advise Parent orally and, if requested by Parent, in writing of any material change with respect to the Company or any Subsidiary.

In such connection, Parent agrees that for purposes of any length of service requirements, waiting periods, vesting periods or differential benefits based on length of service in any such benefit programs, each such employee's service with the Company shall be deemed to have been service with Parent or such Affiliate of Parent.

(a) If the Company Stockholder Approval is required by law to consummate the Merger, the Company will, as soon as practicable following the consummation of the Offer, duly call, give notice of, convene and hold a meeting of its stockholders (the "Stockholders Meeting") for the purpose of obtaining the Company Stockholder Approval. The Company will, through its Board of Directors, and subject to such board's fiduciary duties under applicable law after consultation with its outside counsel, recommend to its stockholders that the Company Stockholder Approval be given. Notwithstanding the foregoing, if Sub or any other subsidiary of Parent shall acquire at least 90% of the outstanding Shares, the parties shall, at the request of Parent, take all necessary and appropriate action to cause the Merger to become effective as soon as practicable after the consummation of the Offer without a Stockholders Meeting in accordance with Section 82 of the MBCL. 30 (b) If the Company Stockholder Approval is required by law to consummate the Merger, the Company will, at Parent's request, as soon as practicable following consummation of the Offer, prepare and file a preliminary Proxy Statement with the SEC and will use its best efforts to respond to any comments of the SEC or its staff and to cause the Proxy Statement to be mailed to the Company's stockholders as promptly as practicable after responding to all such comments to the satisfaction of the staff. The Company will notify Parent promptly of the receipt of any comments from the SEC or its staff and of any request by the SEC or its staff for amendments or supplements to the Proxy Statement or for additional information and will supply Parent with copies of all correspondence between the Company or any of its representatives, on the one hand, and the SEC or its staff, on the other hand, with respect to the Proxy Statement or the Merger. If at any time prior to the Stockholders Meeting there shall occur any event that should be set forth in an amendment or supplement to the Proxy Statement, the Company will promptly prepare and mail to its stockholders such an amendment or supplement. The Company will not mail any Proxy Statement, or any amendment or supplement thereto, to which Parent reasonably objects, unless required by law, rule, regulation or the SEC staff, in the opinion of outside counsel; provided, that Parent shall identify its objections and fully cooperate with the Company to create a mutually satisfactory Proxy Statement. In connection with such preliminary proxy statement, Proxy Statement and any amendment or supplement thereto, Parent and Sub should promptly provide all information reasonably requested by the Company. (c) Following the purchase of Shares, if any, pursuant to the Offer, Parent shall ensure that all such Shares purchased continue to be held by Parent, Sub, and/or a direct or indirect wholly-owned subsidiary of Parent until such time as the Merger is consummated.

(a) Upon the terms and subject to the conditions set forth in this Agreement, each of the parties agrees to use all reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Offer and the Merger, and the other transactions contemplated by this Agreement, including (i) the obtaining of all necessary actions or nonactions, waivers, consents and approvals from Governmental Entities and the making of all necessary registrations and filings (including filings with Governmental Entities, if any) and the taking of all reasonable steps as may be necessary to obtain an approval or waiver from, or to avoid an action or proceeding by, any Governmental Entity, (ii) the obtaining of all necessary consents, approvals or waivers from third parties, (iii) the defending of any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of any of the transactions contemplated by this Agreement, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Entity vacated or reversed, and (iv) the execution and delivery of any additional instruments necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement. In connection with and without limiting the foregoing, the Company and its Board of Directors shall (i) take all action necessary to ensure that no state takeover statute or similar statute or regulation is or becomes applicable to the Offer, the Merger, this Agreement, the Stockholder Agreement or any of the other transactions contemplated by this Agreement or the Stockholder Agreement and (ii) if any state takeover statute or similar statute or regulation becomes applicable to the Offer, the Merger, this Agreement, the Stockholder Agreement or any other transaction contemplated by this Agreement or the Stockholder Agreement, take all action reasonably necessary to ensure that the Offer, the Merger and the other transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on the Offer, the Merger, this Agreement, the Stockholder Agreement and the other transactions contemplated by this Agreement or the Stockholder Agreement. Nothing in this Agreement shall be deemed to require Parent to dispose of or hold separate any asset or collection of assets. (b) Each of the Company and Parent shall keep the other apprised of the status of matters relating to completion of the transactions contemplated by this Agreement, including promptly furnishing the other with copies of notices or other communications received by Parent or the Company, as the case may be, or their respective Subsidiaries, from any third party and/or any Governmental Entity alleging that the consent of such third party or Governmental Entity is or may be required with respect to the Offer, the Merger and the other transactions contemplated by this Agreement. Each of the Company and Parent shall give prompt notice to the other of (i) the occurrence or non-occurrence of any fact or event which would be reasonably likely (x) to cause any representation or warranty contained in this Agreement to be untrue or inaccurate at any time from the date hereof to the Effective Time or (y) to cause any covenant, condition or agreement under this Agreement not to be complied with or satisfied and (ii) any failure of the Company, 32 Parent or Sub, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder; provided, however, that no such notification shall affect the representations, warranties, covenants or agreement of the parties or the conditions to the obligations of the parties under this Agreement. 7.4 Stock Option Plans and Warrants; Employee Stock Purchase Plan.

Promptly upon the acceptance for payment of, and payment for, any Shares by Sub pursuant to and subject to the conditions (including the Minimum Condition) of the Offer, Sub shall be entitled to designate such number of directors on the Board of Directors of the Company as will give Sub, subject to compliance with Section 14(f) of the Exchange Act, a majority of such directors, and the Company shall, at such time, cause Sub's designees to be so elected by its existing Board of Directors. Subject to applicable law, the Company shall take all action requested by Parent necessary to effect any such election, including mailing to its stockholders the Information Statement containing the information required by Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder, and the Company agrees to make such mailing with the mailing of the Schedule 14D-9 (provided that Parent and Sub shall have provided to the Company on a timely basis in writing all information required to be included in the Information Statement and Schedule 14D-9 with respect to Sub's designees).

(b) In the event that this Agreement is terminated (i) by Parent or Sub pursuant to Section 9.1(c), (ii) by Parent pursuant to and in accordance with Section 9.1(b)(i)(x) if such termination results from the failure of the Offer Conditions described in paragraphs (c), (f) or (h) of Exhibit A as a result of any breach by the Company of any covenant or agreement (including, without limitation, the covenants set forth in Section 6.2(b)) or any representation or warranty made by the Company in this Agreement or (iii) pursuant to Section 9.1(d), in each case, in lieu of any liability or obligation to pay damages, the Company shall promptly pay to Parent in immediately available funds a termination fee including all Expenses (as defined herein) equal to One Million and No/100 Dollars ($1,000,000.00). The Company acknowledges that the agreements contained in this Section 7.7(b) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Parent would not enter into this Agreement.

(c) By Parent or Sub prior to Sub's obligation to accept Shares for payment pursuant to the Offer in the event of a material breach by the Company of any representation, warranty, covenant or other agreement contained in this Agreement which would or reasonably would be expected to give rise to the failure of a condition set forth in Exhibit A.

(e) By the Company, if Sub or Parent shall have (i) failed to commence the Offer within five business days of the date hereof, (ii) failed to pay for Shares pursuant to the Offer to the extent required by Section 1.1(a) hereof or (iii) breached in any material respect any of their respective representations, warranties, other covenants or other agreements contained in this Agreement, which breach or failure to perform in respect of clause (iii) is incapable of being cured or has not been cured within 30 days after the giving of written notice to Parent or Sub, as applicable, except, in any case under clause (iii), such breaches and failures which would not prevent the consummation of the Offer or the Merger subject to the terms and conditions of this Agreement. 9.2 Effect of Termination.

Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party.
