THIS AGREEMENT AND PLAN OF MERGER (this “Agreement”), dated as of August 9, 2010, is by and among Endo Pharmaceuticals Holdings Inc., a Delaware corporation (“Parent”), West Acquisition Corp., a Delaware corporation and an indirect, wholly-owned Subsidiary of Parent (“Merger Sub”), and Penwest Pharmaceuticals Co., a Washington corporation (the “Company”).

W I T N E S S E T H:

WHEREAS, Parent desires to acquire the Company on the terms and subject to the conditions set forth in this Agreement;

WHEREAS in furtherance of the acquisition of the Company by Parent, Parent proposes to cause Merger Sub to commence an offer (as it may be amended from time to time as permitted under this Agreement, the “Offer”) to purchase all of the outstanding shares of common stock, par value $0.001 per share, of the Company (the “Company Common Stock”) at a price per share of Company Common Stock of $5.00, net to the seller in cash, without interest (such consideration or any other consideration paid per share pursuant to the Offer, the “Offer Price”), upon the terms and subject to the conditions set forth in this Agreement;

WHEREAS, it is proposed that, on the terms and subject to the conditions set forth in this Agreement, following the consummation of the Offer, Merger Sub shall, in accordance with the Washington Business Corporation Act (the “WBCA”) and the General Corporation Law of the State of Delaware (the “DGCL”), merge with and into the Company (the “Merger”), pursuant to which each share of Company Common Stock, other than (i) shares of Company Common Stock directly or indirectly owned by Parent, Merger Sub or the Company and (ii) Dissenting Shares, will be converted into the right to receive the Merger Consideration;

WHEREAS, the board of directors of the Company (the “Company Board”) has unanimously (i) determined that the Offer, the Merger and the other transactions contemplated hereby (the “Transactions”), are advisable, fair to and in the best interests of the shareholders of the Company, (ii) adopted and approved this Agreement and the Transactions and declared it advisable that the Company enter into this Agreement and consummate the Transactions, (iii) resolved to recommend that the Company’s shareholders accept the Offer and approve the Merger and the Plan of Merger and (iv) taken all actions so that the restrictions contained in the Articles of Incorporation and the WBCA applicable to a “significant business transaction” (as defined in Chapter 23B.19 of the WBCA) will not apply to the execution, delivery or performance of this Agreement or the Shareholder Tender Agreements (as defined below), or to the consummation of the Transactions, including the Merger;

WHEREAS, the Continuing Directors of the Company (as such term is defined in the Company’s Articles of Incorporation), voting separately as a subclass of the Company Board, have unanimously adopted and approved this Agreement and the Merger pursuant to Section 13.2.2 of the Company’s Articles of Incorporation, including the Merger;

WHEREAS, the board of directors of Merger Sub has adopted, approved and declared it advisable for Merger Sub to enter into this Agreement and to consummate the Transactions upon the terms and subject to the conditions set forth herein;

WHEREAS, the board of directors of Parent has approved this Agreement and the Transactions, and Parent, in its capacity as the sole shareholder of Merger Sub, has adopted and approved the Merger and the Plan of Merger upon the terms and subject to the conditions set forth herein;

WHEREAS, concurrently with the execution and delivery of this Agreement, Parent and Merger Sub have entered into a Shareholder Tender Agreement in the form attached as Exhibit B hereto with each of Tang Capital Partners L.P., Xxxxx X. Xxxx, Perceptive Advisors LLC and Xxxxxxxx Xxxx (collectively, the “Shareholder Tender Agreements”), pursuant to which, among other things, each of them has irrevocably agreed to tender shares of Company Common Stock beneficially owned by them in the Offer (the shares subject to such agreements constituting, in the aggregate, approximately 38.6% of the fully diluted Company Common Stock on the date hereof); and

WHEREAS, concurrently with the execution and delivery of this Agreement, Parent and the Company will enter into the Sixth Amendment to the Amended and Restated Strategic Alliance Agreement in the form attached as Exhibit D hereto, effective in accordance with its terms;

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements contained in this Agreement and intending to be legally bound hereby, the parties hereto agree as follows:

ARTICLE I

THE OFFER

Section 1.1 The Offer.

(a) Upon the terms and subject to the conditions of this Agreement (including ARTICLE VIII), as promptly as practicable (but in no event later than August 20, 2010), Merger Sub shall, and Parent shall cause Merger Sub to, commence, within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended (together with the rules and regulations promulgated thereunder, the “Exchange Act”), the Offer; provided, that the Company agrees that no shares of Company Common Stock owned by the Company will be tendered pursuant to the Offer. The obligations of Merger Sub to, and of Parent to cause Merger Sub to, accept for payment, and pay for, any shares of Company Common Stock tendered pursuant to the Offer are subject only to the satisfaction or waiver (to the extent permitted under this Agreement) of the conditions set forth in Exhibit A (as they may be amended in accordance with this Agreement, the “Offer Conditions”).

(i) The initial Expiration Date (defined in Exhibit A) shall be 12:00 midnight, New York City time, at the end of the 20^th Business Day following commencement of the Offer (determined pursuant to Rules 14d-1(g)(3) and 14d-2 under

- 2 -

the Exchange Act). Merger Sub expressly reserves the right, at any time, to, in its sole discretion, waive, in whole or in part, any Offer Condition or modify the terms of the Offer; provided, however, that, without the prior written consent of the Company, Merger Sub shall not (A) reduce the number of shares of Company Common Stock subject to the Offer, (B) reduce the Offer Price or change the form of consideration payable in the Offer, (C) change, modify or waive the Minimum Tender Condition (as defined in Exhibit A), (D) impose conditions to the Offer that are different than or in addition to the Offer Conditions, (E) extend the Offer except as provided in this Section 1.1 for a period of five (5) Business Days on each such occasion or (F) otherwise amend the Offer in any manner adverse to the holders of Company Common Stock or that would reasonably be expected to prevent, materially delay or impair the ability of Parent or Merger Sub to consummate the Offer, the Merger or the other Transactions.

(ii) Notwithstanding anything in this Agreement to the contrary, Merger Sub (A) may, in its sole discretion (subject to the obligations of Parent and Merger Sub under Section 1.1(a)(ii)(B) and Section 1.1(a)(iii)), without consent of the Company, extend the Offer on one or more occasions for a period of five (5) Business Days on each such occasion if, on any then-scheduled Expiration Date (defined in Exhibit A), any of the Offer Conditions shall not be satisfied or, in Merger Sub’s sole discretion, waived (if permitted under this Agreement) until such time as such condition or conditions are satisfied or waived and (B) shall extend the Offer for any period required by any rule, regulation, interpretation or position of the United States Securities and Exchange Commission (the “SEC”), the staff thereof or the Nasdaq Stock Market (the “Nasdaq”) applicable to the Offer, and until any waiting period (and any extension thereof) applicable to the consummation of the Offer under the Xxxx-Xxxxx-Xxxxxx Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and any other applicable foreign antitrust, competition or similar Law shall have expired or been terminated; provided, however, that in no event shall Merger Sub be required to extend the Offer (1) beyond the Outside Date or (2) at any time that Parent or Merger Sub is permitted to terminate this Agreement pursuant to ARTICLE VIII.

(iii) In addition to the extension obligation set forth in Section 1.1(a)(ii)(B), Parent and Merger Sub agree that if on any scheduled Expiration Date of the Offer, the Minimum Tender Condition is not satisfied but all of the other Offer Conditions set forth in Exhibit A are satisfied or, in Merger Sub’s sole discretion, waived, then Merger Sub shall, and Parent shall cause Merger Sub to, on each of the first two such scheduled expiration dates, extend the Offer for periods of five (5) Business Days on each such occasion; provided, however, that this provision shall not require Merger Sub to extend the expiration of the Offer more than two times, for five (5) Business Days on each such occasion, and in no event shall Merger Sub be required to extend the Offer (1) beyond the Outside Date or (2) at any time that Parent or Merger Sub is permitted to terminate this Agreement pursuant to ARTICLE VIII.

(iv) On the terms and subject to the conditions of this Agreement, Merger Sub shall, and Parent shall cause Merger Sub to, accept and pay for (subject to any applicable Tax withholding pursuant to Section 1.1(d)) all shares of Company Common Stock validly tendered and not validly withdrawn pursuant to the Offer as soon as

- 3 -

practicable after the Expiration Date (defined in Exhibit A) (as it may be extended and re-extended in accordance with this Section 1.1(a)). The Offer Price payable in respect of each share of Company Common Stock pursuant to the preceding sentence shall be paid net to the seller in cash, without interest, on the terms and subject to the conditions of this Agreement. Acceptance for payment of shares of Company Common Stock pursuant to and subject to the conditions of the Offer upon the expiration of the Offer is referred to in this Agreement as the “Offer Closing,” and the date on which the Offer Closing occurs is referred to in this Agreement as the “Offer Closing Date.” Merger Sub expressly reserves the right to, in its sole discretion, following the Offer Closing, extend the Offer for a “subsequent offering period” in accordance with Rule 14d-11 under the Exchange Act; provided, however, such period (including any extensions thereof) shall not exceed twenty (20) Business Days. The Offer Documents (as defined below) may, in Merger Sub’s sole discretion, provide for such a reservation of right.

(v) Nothing contained in this Section 1.1(a) shall affect any termination rights in ARTICLE VIII. Unless this Agreement is terminated pursuant to Section 8.1, neither Parent nor Merger Sub shall terminate or withdraw the Offer prior to any scheduled Expiration Date without the prior written consent of the Company in its sole discretion. In the event this Agreement is terminated pursuant to Section 8.1, Merger Sub shall promptly (and in any event within one (1) Business Day) following such termination irrevocably and unconditionally terminate the Offer and shall not acquire any shares of Company Common Stock pursuant thereto. If the Offer is terminated in accordance with this Agreement prior to the purchase of shares of Company Common Stock in the Offer, Merger Sub shall promptly return, or cause any depositary acting on behalf of Merger Sub to promptly return, all tendered shares to the tendering shareholders.

(b) On the date of commencement of the Offer, Parent and Merger Sub shall file with the SEC a Tender Offer Statement on Schedule TO with respect to the Offer (together with all amendments and supplements thereto and including exhibits thereto, the “Schedule TO”), which shall contain an offer to purchase and a related letter of transmittal and summary advertisement and other appropriate ancillary offer documents (such Schedule TO and the documents included therein pursuant to which the Offer will be made, together with any supplements or amendments thereto, the “Offer Documents”), and cause the Offer Documents to be disseminated to the shareholders of the Company as and to the extent required by United States federal securities Laws. The Company shall promptly furnish or otherwise make available to Parent or Parent’s legal counsel in writing upon request all information concerning the Company that may be required by applicable securities Laws or be reasonably requested by Parent in connection with any action contemplated by this Section 1.1(b). Parent shall cause the Schedule TO and other Offer Documents to comply in all material respects with the provisions of applicable Law. Each of Parent, Merger Sub and the Company shall promptly correct any information supplied by it for inclusion or incorporation by reference in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect, and each of Parent and Merger Sub shall take all steps necessary to amend or supplement the Offer Documents and to cause the Offer Documents as so amended or supplemented to be filed with the SEC and disseminated to the shareholders of the Company, in each case as soon as reasonably practicable and as and to the extent required by applicable

- 4 -

United States federal securities Laws. Parent and Merger Sub shall promptly notify the Company upon the receipt of any comments from the SEC, or any request from the SEC for amendments or supplements, to the Offer Documents, and shall promptly provide the Company with copies of all correspondence and summaries of all material oral communications between them and their Representatives, on the one hand, and the SEC, on the other hand. Prior to the filing of the Offer Documents (including any amendment or supplement thereto) with the SEC or dissemination thereof to the shareholders of the Company, or responding to any comments of the SEC with respect to the Offer Documents, Parent and Merger Sub shall provide the Company and its counsel a reasonable opportunity to review and comment on such Offer Documents or response, and Parent and Merger Sub shall give reasonable and good faith consideration to any such comments. In the event that Parent or Merger Sub receives any comments from the SEC or its staff with respect to the Offer Documents, each shall use its reasonable best efforts to (i) respond promptly to such comments and (ii) take all other actions necessary to resolve the issues raised therein.

(i) holders of Company Options (whether or not such Company Options shall otherwise be exercisable) may tender shares of Company Common Stock issuable upon exercise of such Company Options pursuant to the Offer by delivering to the Paying Agent prior to the Offer Closing such documents as may be required pursuant to the terms of the Company Options to effect the exercise thereof for shares of Company Common Stock (other than payment of the exercise price of such Company Options) (together with all other documentation required in connection with the valid tender of shares of Company Common Stock pursuant to the Offer), provided, that such exercise shall not be deemed to occur unless and until Merger Sub accepts for payment and pays for shares of Company Common Stock tendered pursuant to the Offer at the Offer Closing. Any exercise of Company Options in accordance with this Section shall be deemed to have occurred as of immediately prior to the Offer Closing, and such Paying Agent shall pay to the holder of the Company Options the aggregate Offer Price with respect to the shares of Company Common Stock issuable upon exercise of the Company Options less an amount equal to the aggregate exercise price of such Company Options so exercised. Holders of Company Options that tender shares of Company Common Stock issuable upon exercise of such Company Options in accordance with this Section shall have the right to withdraw such tender (and revoke the related conditional exercise of such Company Options) on the same terms and conditions as would apply if they had tendered outstanding shares of Company Common Stock into the Offer.

(ii) holders of Company Warrants (whether or not such Company Warrants shall otherwise be exercisable) may tender shares of Company Common Stock issuable upon exercise of such Company Warrants pursuant to the Offer by delivering to the Paying Agent prior to the Offer Closing such documents as may be required pursuant to the terms of the Company Warrants to effect the exercise thereof for shares of Company Common Stock (other than payment of the exercise price of such Company Warrants) (together with all other documentation required in connection with the valid tender of shares of Company Common Stock pursuant to the Offer), provided, that such

- 5 -

exercise shall not be deemed to occur unless and until Merger Sub accepts for payment and pays for shares of Company Common Stock tendered pursuant to the Offer at the Offer Closing. Any exercise of Company Warrants in accordance with this Section shall be deemed to have occurred as of immediately prior to the Offer Closing, and such Paying Agent shall pay to the holder of the Company Warrants the aggregate Offer Price with respect to the shares of Company Common Stock issuable upon exercise of the Company Warrants less an amount equal to the aggregate exercise price of such Company Warrants so exercised. Holders of Company Warrants that tender shares of Company Common Stock issuable upon exercise of such Company Warrants in accordance with this Section shall have the right to withdraw such tender (and revoke the related conditional exercise of such Company Warrants) on the same terms and conditions as would apply if they had tendered outstanding shares of Company Common Stock into the Offer.

(d) Parent shall provide or cause to be provided to Merger Sub on a timely basis the consideration necessary to pay for any Company Stock Rights that Merger Sub becomes obligated to accept for payment and pay for pursuant to the Offer, and shall cause Merger Sub to fulfill all of Merger Sub’s obligations under this Agreement.

(e) Parent, Merger Sub, and the paying agent for the Offer (the “Paying Agent”) shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to the Offer to any holder of Company Stock Rights such amounts as Parent, Merger Sub, or the Paying Agent, as applicable, is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), and Treasury Regulations promulgated thereunder, or any other provision of Tax Law. To the extent that amounts are so withheld and paid over by Parent, Merger Sub or the Paying Agent, as applicable, to the appropriate taxing authority, such withheld amounts shall be treated for all purposes as having been paid to the holder of the Company Stock Rights to whom such withheld amounts would otherwise have been paid.

Section 1.2 Company Actions.

(a) The Company hereby approves and consents to the Transactions and represents that:

(i) the Company Board, at a meeting duly called and held, has unanimously:

(A) determined that the Transactions are advisable, fair to and in the best interests of the shareholders of the Company;

(B) adopted and approved this Agreement and the Transactions and declared it advisable that the Company enter into this Agreement and consummate the Transactions;

(C) resolved to recommend that the Company’s shareholders accept the Offer and approve the Merger and the Plan of Merger; and

(ii) the Continuing Directors of the Company (as such term is defined in the Company’s Articles of Incorporation), voting separately as a subclass of the Company Board, have unanimously adopted and approved this Agreement and the Merger pursuant to Section 13.2.2 of the Company’s Articles of Incorporation.

(b) On the date the Offer Documents are filed with the SEC, the Company shall file with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the Offer (such Schedule 14D-9, together with any supplements or amendments thereto, the “Schedule 14D-9”) containing, subject to Section 6.5(b), the recommendation described in Section 1.2(a)(iii) and shall disseminate the Schedule 14D-9 to the shareholders of the Company as and to the extent required by Rule 14d-9 under the Exchange Act. Each of Parent and Merger Sub shall promptly furnish or otherwise make available to the Company or the Company’s legal counsel in writing upon request all information concerning Parent and Merger Sub that may be required by applicable securities Laws or reasonably requested by the Company for inclusion in the Schedule 14D-9. The Company shall cause the Schedule 14D-9 to comply in all material respects with the provisions of applicable Law. Each of the Company, Parent, and Merger Sub shall promptly correct any information supplied by it for inclusion or incorporation by reference 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 shall 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 shareholders of the Company, in each case as soon as reasonably practicable and as and to the extent required by applicable United States federal securities Laws. The Company shall promptly notify Parent upon the receipt of any comments from the SEC, or any request from the SEC for amendments or supplements, to the Schedule 14D-9, and shall promptly provide Parent with copies of all correspondence and summaries of all material oral communications between the Company and its Representatives, on the one hand, and the SEC, on the other hand. Prior to the filing of the Schedule 14D-9 (including any amendment or supplement thereto) that does not contain or relate to a Company Adverse Recommendation Change with the SEC or mailing thereof to the shareholders of the Company, or responding to any comments of the SEC with respect to the Schedule 14D-9, the Company shall provide Parent, Merger Sub and their counsel a reasonable opportunity to review and comment on such Schedule 14D-9 or response, and the Company shall give reasonable and good faith consideration to any such comments. The Company hereby consents to the inclusion in the Offer Documents of the recommendation of the Company Board contained in the Schedule 14D-9. In the event that the Company receives any comments from the SEC or its staff with respect to the Schedule 14D-9, it shall use its reasonable best efforts to (i) respond promptly to such comments and (ii) take all other actions necessary to resolve the issues raised therein.

(c) In connection with the Offer and the Merger, the Company shall instruct its transfer agent to furnish Parent and Merger Sub promptly with mailing labels containing the names and addresses of the record holders of Company Common Stock as of the latest

- 7 -

practicable date, together with copies of all lists of shareholders, security position listings and computer files and all other information in the Company’s possession or control regarding the beneficial owners of Company Common Stock, in each case as of the latest date practicable, and shall furnish to Parent and Merger Sub such information and assistance (including periodically updated lists of shareholders, security position listings and computer files) as Parent may reasonably request in communicating the Offer to holders of Company Common Stock. Except for such steps as are necessary to disseminate the Offer Documents and any other documents necessary to consummate the Offer or the Merger, Parent, Merger Sub and their respective affiliates, associates and Representatives shall use the information contained in any such labels, listings and files only in connection with the Offer and the Merger, shall treat such information and materials in accordance with the terms and conditions of the Confidentiality Agreement, and, if this Agreement shall be terminated, will deliver to the Company all copies of such information then in their possession or under their control promptly upon the request of the Company.

Section 1.3 Directors.

(a) Effective upon the Offer Closing and from time to time thereafter, Parent shall be entitled to designate the number of directors, rounded up to the next whole number, on the Company Board that equals the product of (i) the total number of directors on the Company Board (giving effect to the election of any additional directors pursuant to this Section 1.3) and (ii) the percentage that the number of shares of Company Common Stock beneficially owned by Parent and/or Merger Sub (including shares accepted for payment pursuant to the Offer) bears to the total number of shares outstanding, and the Company shall, promptly following Parent’s written request, cause Parent’s designees to be elected or appointed to the Company Board, including by increasing the number of directors and seeking and accepting resignations of incumbent directors (with such method to be by the election of Parent, including the selection of the individuals designated for resignation). The Company shall take such actions necessary to cause Parent’s designees to be Continuing Directors under the Company’s Articles of Incorporation. At each such time, the Company shall also cause individuals designated by Parent to constitute the proportional number of members, rounded up to the next whole number, on each committee of the Company Board in proportion to the number of directors designated by Parent to the Company Board, to the extent permitted by applicable Law and the Nasdaq Marketplace Rules.

(b) The Company’s obligations to appoint Parent’s designees to the Company Board shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder and, to the extent applicable to a “controlled company,” the Nasdaq Marketplace Rules. The Company shall promptly take all actions necessary to effect the appointment of Parent’s designees, including mailing to its shareholders such information with respect to the Company and its officers and directors as Section 14(f) and Rule 14f-1 require in order to fulfill its obligations under this Section 1.3(b), which, unless Parent otherwise elects, shall be mailed together with the Schedule 14D-9.

ARTICLE III

EFFECTS OF THE MERGER; EXCHANGE OF CERTIFICATES

Section 3.1 Effect on Capital Stock. Upon the terms and subject to the conditions of this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holders of any shares of Company Common Stock or of any shares of capital stock of Parent or Merger Sub:

(a) Conversion of Company Common Stock. Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (including without limitation all vested and unvested shares of restricted stock, but not including shares to be cancelled pursuant to Section 3.1(c) hereof and Dissenting Shares) shall be converted into the

- 10 -

right to receive in cash an amount equal to the Offer Price paid in the Offer (the “Merger Consideration”). As of the Effective Time, all such shares of Company Common Stock shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of any Company Common Stock shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration, to be issued or paid in consideration therefor in accordance with Section 3.2, without interest.

(b) Conversion of Merger Sub Common Stock. Each share of common stock, par value $0.01 per share, of Merger Sub (the “Merger Sub Common Stock”) that is issued and outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and nonassessable share of common stock, par value $0.001 per share, of the Surviving Corporation, and the shares of the Surviving Corporation into which the shares of Merger Sub Common Stock are so converted shall be the only shares of the Surviving Corporation that are issued and outstanding immediately after the Effective Time. Following the Effective Time, each certificate evidencing ownership of shares of Merger Sub Common Stock shall evidence ownership of such shares of the Surviving Corporation.

(c) Cancellation of Certain Shares. Each share, if any, of Company Common Stock that is owned by Parent or by any direct or indirect wholly-owned Subsidiary of Parent shall be cancelled without any conversion, and no consideration shall be delivered in respect thereof.

(d) Company Options. Effective as of the Closing, the Company Stock Plans and all Company Options outstanding immediately before the Closing shall be cancelled and of no further force or effect. In consideration for such cancellation of Company Options outstanding under the Company Stock Plans immediately before the Closing, the holders thereof (whether or not such Company Options shall otherwise be exercisable at the Effective Time) shall automatically (and without any further action being required on the part of the holders thereof) receive, at the Effective Time, an amount of cash equal to (i) the number of shares of Company Common Stock subject to each such Company Option held by such holder multiplied by (ii) the excess, if any, of (A) the Merger Consideration over (B) the per-share exercise price under such Company Option (with such payments to be subject to any applicable Tax withholding in accordance with Section 3.1(h)).

(e) Company Warrants. Effective as of the Closing, each warrant to acquire shares of Company Common Stock (collectively, “Company Warrants”) shall become a warrant to receive, subject to the conditions set forth therein, an amount of cash determined pursuant to the terms of such Company Warrant. The Company shall give notice of the Merger to the holders of Company Warrants as required pursuant to the terms thereof. Following the Closing, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, pay any consideration owed to a holder of a Company Warrant in accordance with the terms of such Company Warrant.

(f) Other Equity Awards. Prior to the Effective Time, the Company shall take all actions necessary such that no Person has any rights to acquire Company Common Stock or common stock of the Parent or any of its Subsidiaries (including the Surviving Corporation) pursuant to any Company Benefit Plan or Company Benefit Agreement following the Effective Time.

- 11 -

(g) Employee Stock Purchase Plan. After the date hereof, no future offering periods shall be commenced under Company’s 1997 Employee Stock Purchase Plan (the “ESPP”). Prior to the Effective Time, the Company shall take all actions necessary such that effective as of immediately prior to the Closing the ESPP shall terminate and no Person shall hold any right to acquire Company Stock pursuant to the ESPP on or following the Effective Time.

(h) Withholding. Parent, the Company, the Surviving Corporation and the Exchange Agent shall be entitled to deduct from the consideration otherwise payable pursuant to this Agreement to any holder of Company Options or Company Warrants such amounts as Parent, the Company, the Surviving Corporation or the Exchange Agent, as applicable, is or may be required to deduct and withhold with respect to the making of such payment under the Code and Treasury Regulations promulgated thereunder, or any other provision of Tax Law. To the extent that amounts are so withheld and paid over to the appropriate taxing authority by Parent, the Company, the Surviving Corporation or the Exchange Agent, as applicable, such withheld amounts shall be treated for all purposes as having been paid to the holder of the Company Options or Company Warrants to whom such withheld amounts would otherwise have been paid.

(i) Adjustments to Merger Consideration. The Merger Consideration shall be adjusted to reflect fully the effect of any reclassification, stock split, reverse split, stock dividend (including any dividend or distribution of securities convertible into Company Common Stock), reorganization, recapitalization or other like change with respect to Company Common Stock occurring (or for which a record date is established) after the date hereof and prior to the Effective Time.

Section 3.2 Exchange of Shares and Certificates.

(a) Exchange Agent. At or prior to the Effective Time, Parent shall engage a nationally recognized financial institution reasonably satisfactory to the Company to act as exchange agent in connection with the Merger (the “Exchange Agent”). At the Effective Time, Parent shall deposit with the Exchange Agent, in trust for the benefit of the holders of shares of Company Common Stock immediately prior to the Effective Time, the Merger Consideration to be paid in respect of Company Common Stock. All cash deposited with the Exchange Agent shall hereinafter be referred to as the “Exchange Fund.”

(b) Exchange Procedures. Promptly after the Effective Time, Parent shall cause the Exchange Agent to mail to each holder of record of (i) a certificate or certificates that immediately prior to the Effective Time represented outstanding shares of Company Common Stock (the “Certificates”) or (ii) uncertificated shares of Company Common Stock represented by book-entry (the “Uncertificated Shares”), in each case, which at the Effective Time were converted into the right to receive the Merger Consideration pursuant to Section 3.1, (A) a letter of transmittal (which, in the case of the Certificates, shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Parent may

- 12 -

reasonably specify) and (B) instructions for use in effecting the surrender of the Certificates or Uncertificated Shares in exchange for the Merger Consideration. Upon (1) surrender of the Certificates for cancellation to the Exchange Agent or receipt of an “agent’s message” by the Exchange Agent (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto and (2) such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificates or Uncertificated Shares shall be entitled to receive in exchange the portion of the Merger Consideration to which such holder is entitled pursuant to Section 3.1, and any Certificates so surrendered shall forthwith be cancelled. If any portion of the Merger Consideration is to be paid to a Person, other than the Person in whose name the surrendered Certificate or the transferred Uncertificated Share is registered, it shall be a condition to such payment that (I) either such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer or such Uncertificated Share shall be properly transferred and (II) the Person requesting such payment shall pay to the Exchange Agent any transfer or other Taxes required as a result of such payment to a Person other than the registered holder of such Certificate or Uncertificated Share or establish to the satisfaction of Parent that such Tax has been paid or is not payable. Until surrendered as contemplated by this Section 3.2(b), each Certificate or Uncertificated Share shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration upon such surrender.

(c) No Further Ownership Rights in Company Common Stock. All Merger Consideration issued and paid upon the surrender for exchange of the Certificates or Uncertificated Shares in accordance with the terms of this ARTICLE III shall be deemed to have been issued and paid in full satisfaction of all rights pertaining to the shares of Company Common Stock previously represented by such Certificates or Uncertificated Shares. 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 of Company Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificates or Uncertificated Shares are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this ARTICLE III.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund (including any interest received with respect thereto) which remains undistributed to the holders of Company Common Stock twelve (12) months after the Effective Time shall be delivered to Parent, upon demand, and any holders of Company Common Stock who have not theretofore complied with this ARTICLE III shall thereafter look only to Parent (subject to abandoned property, escheat or other similar Laws) for payment of their claim for the Merger Consideration.

(e) No Liability. None of Parent, Merger Sub, the Company or the Exchange Agent or any of their respective directors, officers, employees and agents shall be liable to any Person in respect of the Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. Any cash remaining in the Exchange Fund that is unclaimed by holders of Certificates or Uncertificated Shares as of a date immediately prior to such time that such amounts would otherwise escheat to or become property of a Governmental Authority shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation on such date, free and clear of all claims or interests of any Person previously entitled thereto.

- 13 -

(f) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent on a daily basis; provided, that no such investment or loss thereon shall affect the amounts payable to former shareholders of the Company after the Effective Time pursuant to this ARTICLE III. If at any time the funds held in the Exchange Fund are insufficient to satisfy the obligations of Parent and/or Merger Sub under this Agreement, Parent shall or shall cause Merger Sub to promptly deposit additional funds held in the Exchange Fund such that the funds held in the Exchange Fund are thereafter sufficient to satisfy the obligations of Parent and Merger Sub hereunder. Any interest and other income resulting from such investment shall become a part of the Exchange Fund, and any amounts in excess of the amounts payable pursuant to this ARTICLE III shall promptly be paid to Parent.

(g) Withholding Rights. Parent and the Exchange Agent shall be entitled to deduct and withhold from any consideration payable pursuant to this Agreement to any Person that was a holder of Company Common Stock immediately prior to the Effective Time such amounts as Parent or the Exchange Agent, as applicable, is or may be required to deduct and withhold with respect to the making of such payment under the Code and Treasury Regulations promulgated thereunder and under any other provision of Tax Law. To the extent that amounts are so withheld and paid over to the appropriate taxing authority by Parent or the Exchange Agent, as applicable, such withheld amounts shall be treated for all purposes as having been paid to the Person to whom such withheld amounts would otherwise have been paid.

(h) Lost, Stolen or Destroyed Certificates. In the event any Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making and delivery of an affidavit of that fact by the holder thereof and delivery of a properly completed letter of transmittal to the Exchange Agent, such portion of the Merger Consideration as may be required pursuant to Section 3.1(a); provided, however, that Parent may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificates to deliver an agreement of indemnification in form reasonably satisfactory to Parent, or a bond in such sum as Parent may reasonably direct as indemnity, against any claim that may be made against Parent or the Exchange Agent in respect of the Certificates alleged to have been lost, stolen or destroyed.

Section 3.3 Dissenting Shares.

(a) Notwithstanding anything in this Agreement other than Section 3.3(b) hereof to the contrary, any shares of Company Common Stock that are issued and outstanding immediately prior to the Effective Time and held by a shareholder who is entitled to dissent from the Merger under Chapter 23B.13 of the WBCA and who has exercised, when and in the manner required by Chapter 23B.13 of the WBCA to the extent so required prior to the Effective Time, such right to dissent and to obtain payment of the fair value of such shares under Chapter 23B.13 of the WBCA in connection with the Merger (the “Dissenting Shares”) shall not be converted into the right to receive the Merger Consideration unless and until such shareholder shall have effectively withdrawn or lost (through failure to perfect or otherwise) such shareholder’s right to obtain payment of the fair value of such shareholder’s Dissenting Shares under Chapter 23B.13

- 14 -

of the WBCA, but shall instead be entitled only to such rights with respect to such Dissenting Shares as may be granted to such shareholder under Chapter 23B.13 of the WBCA. From and after the Effective Time, Dissenting Shares shall not be entitled to vote for any purpose or be entitled to the payment of dividends or other distributions (except dividends or other distributions payable to shareholders of record prior to the Effective Time), and holders of Dissenting Shares shall have no rights as a shareholder of the Surviving Corporation with respect to such Dissenting Shares, except those provided under Chapter 23B.13 of the WBCA.

(b) If any shareholder who holds Dissenting Shares effectively withdraws or loses (through failure to perfect or otherwise) such shareholder’s right to obtain payment of the fair value of such shareholder’s Dissenting Shares under Chapter 23B.13 of the WBCA, then, as of the later of the Effective Time and the occurrence of such effective withdrawal or loss, such shareholder’s shares of Company Common Stock shall no longer be Dissenting Shares and, if the occurrence of such effective withdrawal or loss is later than the Effective Time, shall be treated as if they had as of the Effective Time been converted into the right to receive the Merger Consideration, without any interest thereon, as set forth in Section 3.1(a) or converted or cancelled in accordance with of Sections 3.1(b) or (c), as applicable.

(c) The Company shall give Parent (i) prompt notice of any notices of intent to demand payment for any shares of Company Common Stock, attempted withdrawals of such demands for payment and any other instruments served pursuant to the WBCA and received by the Company relating to the exercise of dissenters’ rights under Chapter 23B.13 of the WBCA and (ii) the opportunity to participate in all negotiations and proceedings that take place prior to the Effective Time with respect to the exercise of dissenters’ rights under the WBCA. Except with the prior written consent of Parent, the Company shall not voluntarily make any payment with respect to the exercise of dissenters’ rights or settle or offer to settle any demands for payment with respect to Dissenting Shares.

(a) The Company has all necessary corporate power and authority to execute and deliver this Agreement, to perform its obligations hereunder and, subject to obtaining the Company Shareholder Approval if required in connection with the Merger, to consummate the Transactions. The execution, delivery and performance by the Company of this Agreement and the consummation by the Company of the Transactions, have been duly authorized by all necessary corporate action on the part of the Company and no other corporate proceedings on the

- 17 -

part of the Company are necessary to authorize this Agreement or to consummate the Transactions (other than obtaining the Company Shareholder Approval for consummation of the Merger and the filing and recordation of appropriate merger documents as required by the WBCA). This Agreement has been duly executed and delivered by the Company and, assuming the due authorization, execution and delivery by the other parties hereto, constitutes the legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms subject, as to enforcement of remedies, to bankruptcy, insolvency, reorganization, moratorium or similar Laws affecting the rights and remedies of creditors generally and to the effect of general principles of equity. The affirmative vote of a majority of outstanding shares of Company Common Stock entitled to vote in accordance with the WBCA and the Company Organizational Documents (the “Company Shareholder Approval”) is the only vote of the holders of capital stock of the Company necessary to approve the Merger. No other vote of the holders of the capital stock of the Company is required to approve this Agreement and the Transactions.

(b) The Company Board, at a meeting duly called and held, duly and unanimously adopted resolutions (i) determining that the Transactions are advisable, fair to and in the best interests of the shareholders of the Company, (ii) adopting and approving this Agreement and the Transactions and declaring it advisable that the Company enter into this Agreement and consummate the Transactions, and (iii) recommending that the Company’s shareholders accept the Offer and approve the Merger and the Plan of Merger.

(c) Xxxxxxx Lynch, Pierce, Xxxxxx & Xxxxx Incorporated (“Xxxxxxx Xxxxx”) has delivered to the Company Board an opinion to the effect that, as of the date of such opinion and subject to the assumptions, qualifications and limitations contained therein, the $5.00 per share in cash to be received pursuant to the Offer and the Merger by the holders of Company Common Stock (other than Parent, Merger Sub, any beneficial owner of more than five percent (5%) of the outstanding shares of Company Common Stock who is a reporting person on a Statement of Beneficial Ownership on Schedule 13D (or amendment thereto) filed with the SEC with respect to the Company Common Stock, and their respective affiliates) is fair, from a financial point of view, to such holders. The Company will make available to Parent a correct and complete copy of the form of such opinion solely for informational purposes after receipt thereof by the Company.

Section 4.4 No Conflict. Neither the execution and delivery of this Agreement by the Company nor the consummation by the Company of the Transactions, nor performance of this Agreement by the Company will (a) assuming the Company Shareholder Approval is obtained for the Merger, conflict with or violate the Company Organizational Documents; (b) assuming compliance with Section 4.5 hereof and assuming the Company Shareholder Approval is obtained for consummation of the Merger, conflict with or violate any United States federal, state or local or any foreign statute, law, rule, regulation, ordinance, code or any other requirement or rule of law (a “Law”) or any charge, temporary restraining order or other order, writ, injunction (whether preliminary, permanent or otherwise), judgment, decree, ruling, determination, directive, award or settlement, whether civil, criminal or administrative (an

- 18 -

Parent, use its commercially reasonable efforts to obtain the required consent of any third party to such access or disclosure, it being understood that the Company shall not be required to make any payments in connection with the fulfillment of its obligations under this clause (B)), or (C) result in the loss of attorney-client privilege (provided, that the Company shall use its commercially reasonable efforts to allow for such access or disclosure in a manner that does not result in a loss of attorney-client privilege, it being understood that the Company shall not be required to make any payments in connection with the fulfillment of its obligations under this clause (C)). In addition, the Company and its officers and employees shall reasonably cooperate with Parent, at Parent’s sole cost and expense, in Parent’s efforts to comply with the rules and regulations affecting public companies, including the Xxxxxxxx-Xxxxx Act.

Notwithstanding anything to the contrary in this Agreement, the Company hereby consents to Parent contacting any time after the date hereof those Persons set forth on Section 6.2 of the Company Disclosure Letter in connection with supplies to the Company following the Closing.

Section 6.3 Notification of Certain Matters. Parent shall give prompt notice to the Company and the Company shall give prompt notice to Parent, as the case may be, of the occurrence, or failure to occur, of any event, in each case if known by the party otherwise required to give such notice, which occurrence or failure to occur is reasonably likely to cause (a)(i) any representation or warranty of such party contained in this Agreement that is qualified as to “materiality,” or “Company Material Adverse Effect” to be untrue or inaccurate in any respect or (ii) any other representation or warranty of such party contained in this Agreement to be untrue or inaccurate in any material respect, in each case at any time from and after the date of this Agreement until the Offer Closing or (b) any material failure of Parent or Merger Sub or the Company, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it under this Agreement.

- 43 -

Each party shall use its reasonable best efforts to furnish to each other party all information required for any filing, form, declaration, notification, registration and notice with respect to Competition Laws and the Transactions. Each party shall give the other parties hereto reasonable prior notice of any communication with, and any proposed understanding or agreement with, any Governmental Entity regarding any filings, forms, declarations, notifications, registrations or notices with respect to Competition Laws and the Transactions, and permit the other parties hereto to review and discuss in advance, and consider in good faith the views of the other parties hereto in connection with, any proposed communication, understanding or agreement with any Governmental Entity with respect to the Transactions. None of the parties hereto shall independently participate in any meeting, or engage in any substantive conversation, with any Governmental Entity in respect of any filings or inquiry with respect to Competition Laws and the Transactions without giving the other parties hereto prior notice of the meeting and, unless prohibited by such Governmental Entity, the opportunity to attend and/or participate. The parties hereto will consult and cooperate with one another in connection with any information or proposals submitted in connection with proceedings under or relating to any Competition Law with respect to the Transactions. Without limiting the foregoing, the Company and Parent shall each use its reasonable best efforts: (A) to avoid the entry of any judgment that would restrain, prevent or delay the Closing, (B) to eliminate every impediment under any Competition Law that may be asserted by any Governmental Entity so as to enable the Closing to occur as soon as reasonably possible (and in any event no later than the Outside Date) and (C) vigorously to contest and resist any such action or proceeding, including any administrative or judicial action.

(b) Subject to Section 6.4(c), each of the parties hereto agrees to use its reasonable best 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 hereto in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Transactions, including (i) the obtaining of all other necessary actions or nonactions, waivers, consents, licenses, permits, authorizations, orders and approvals from Governmental Entities and the making of all other necessary registrations and filings (including filings with Governmental Entities, if any), (ii) the obtaining of all consents, approvals or waivers from third parties necessary to consummate the Transactions, (iii) the preparation of the Proxy Statement and any other documents that may be required to be filed with the SEC, (iv) the execution and delivery of any additional instruments reasonably necessary to consummate any of the Transactions, and to fully carry out the purposes of, this Agreement and (v) the providing of all such information concerning such party, its Subsidiaries, its Affiliates and its Subsidiaries’ and Affiliates’ officers, directors, employees and partners as may be reasonably requested in connection with any of the matters set forth in Section 6.4(a) or this Section 6.4(b).

- 44 -

(c) Notwithstanding anything to the contrary in this Section 6.4, neither Parent nor the Company shall be required in order to resolve any objections asserted under Competition Laws by any Governmental Entity with respect to any of the Transactions to divest any of its businesses, product lines or assets, or take or agree to take any other action or agree to any limitation or restriction.

Section 6.5 No Solicitation; Company Board Recommendation.

(a) Except as set forth in this Section 6.5, the Company shall not, nor shall it authorize or permit any of its Representatives to, directly or indirectly, (i) solicit, initiate or knowingly encourage, or take any other action designed to, or which would reasonably be expected to, facilitate, any Company Takeover Proposal, (ii) enter into any agreement with respect to any Company Takeover Proposal, or (iii) enter into, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any Person any information with respect to, or otherwise take any action for the purpose of knowingly encouraging or facilitating, any proposal that constitutes, or would reasonably be expected to lead to, any Company Takeover Proposal. The Company shall, and shall cause its Representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any Person conducted heretofore with respect to any proposal that constitutes, or would reasonably be expected to lead to, any Company Takeover Proposal and request the prompt return or destruction of all confidential information previously furnished pursuant thereto. Notwithstanding the foregoing, at any time prior to the Offer Closing, in response to a bona fide written Company Takeover Proposal that the Company Board in good faith determines (after consultation with outside counsel and a financial advisor of nationally recognized reputation) constitutes, or would reasonably be expected to lead to, a Superior Proposal, and which Company Takeover Proposal did not result from a breach of this Section 6.5(a), the Company may, if a majority of the Company Board determines (after consultation with outside counsel) that failure to take such action would be inconsistent with its fiduciary duties to the shareholders of the Company (including the standards of conduct set forth in Section 23B.08.300 of the WBCA) under applicable Law, and subject to compliance with this Section 6.5(a) and Section 6.5(c) and after giving Parent written notice of such determination, (A) furnish information with respect to the Company to the Person making such Company Takeover Proposal (and its Representatives) pursuant to a customary confidentiality agreement (which agreement shall include a customary “standstill” or similar covenant) and containing provisions allowing necessary disclosures to Parent pursuant to Section 6.5(c) hereof; provided, that (1) all such information has previously been provided to Parent or is provided to Parent at the time it is provided to such Person and (2) such customary confidentiality agreement expressly provides the right for the Company to comply with the terms of this Agreement, including Section 6.5(b) and Section 6.5(c), and (B) participate in discussions or negotiations with the Person making such Company Takeover Proposal (and its Representatives) regarding such Company Takeover Proposal. Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in this Section 6.5(a) by any Representative of the Company shall be deemed to be a breach of this Section 6.5(a) by the Company.

- 45 -

The term “Company Takeover Proposal” means any inquiry, proposal or offer (whether in writing or otherwise) from any Person (other than Parent or Merger Sub) contemplating, or that is reasonably expected to lead to, any direct or indirect acquisition or purchase by such Person, in one transaction or a series of transactions, of assets that generate 20% or more of the revenues or constitute 20% or more of the assets of the Company, or 20% or more of any class of equity securities of the Company, any tender offer or exchange offer that if consummated would result in any Person beneficially owning 20% or more of any class of equity securities of the Company, or any merger, consolidation, business combination, recapitalization, liquidation, dissolution, joint venture, binding share exchange or similar transaction involving the Company pursuant to which any Person or the shareholders of any Person would own 20% or more of any class of equity securities of the Company or of any resulting parent company of the Company, in each case other than any of the Transactions.

The term “Superior Proposal” means a bona fide written proposal that did not arise from a material breach of Section 6.5 or offer constituting a Company Takeover Proposal (provided, that for purposes of this definition references to 20% in the definition of “Company Takeover Proposal” shall be deemed to be references to 50%) which a majority of the Company Board determines in good faith (after consultation with outside counsel and a financial advisor of nationally recognized reputation) to be (i) more favorable to the shareholders of the Company from a financial point of view than the Offer and the Merger, taking into account all relevant factors (including all the terms and conditions of such proposal and the Offer and this Agreement (including any changes to the terms of the Offer and this Agreement proposed by Parent in response to such offer or otherwise)) and (ii) reasonably capable of being completed, taking into account all financial, legal, regulatory and other aspects of such proposal.

(b) Except as set forth in this Section 6.5, neither the Company Board nor any committee thereof shall, (i)(A) withdraw (or qualify or modify in a manner adverse to Parent or Merger Sub), or publicly propose to withdraw (or qualify or modify in a manner adverse to Parent or Merger Sub), the adoption, approval, recommendation or declaration of advisability by the Company Board or any such committee thereof of this Agreement or the Transactions or (B) recommend, adopt, approve or declare advisable, or propose publicly to recommend, adopt, approve or declare advisable, any Company Takeover Proposal (any action described in this clause (i) being referred to as a “Company Adverse Recommendation Change”) or (ii) adopt, approve, recommend or declare advisable, or publicly propose to adopt, approve, recommend or declare advisable, or allow the Company to execute or enter into, any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, or other similar agreement with respect to any Company Takeover Proposal (other than a confidentiality agreement referred to in Section 6.5(a) pursuant to and in accordance with the limitations set forth therein). Notwithstanding the foregoing, at any time prior to the Offer Closing Date, the Company Board may make a Company Adverse Recommendation Change if (x) the Company has received a Company Takeover Proposal that constitutes a Superior Proposal or (y) a development or a change in circumstances occurs or arises after the date of this Agreement that was not known by the Company Board as of the date of this Agreement and, in the case of either of the foregoing clauses (x) or (y), a majority of the Company Board determines (after consultation with outside counsel) that failure to take such action would be inconsistent with its fiduciary duties to the shareholders of the Company (including the standards of conduct set forth in Section 23B.08.300 of the WBCA) under applicable Law; provided,

- 46 -

however, that no such Company Adverse Recommendation Change may be made until after the third (3^rd) Business Day following Parent’s receipt of written notice (a “Company Notice of Adverse Recommendation”) from the Company advising Parent that the Company Board intends to take such action and specifying the reasons therefor, including the terms and conditions of the Superior Proposal, if any, that is the basis of the proposed action by the Company Board (it being understood and agreed that (1) any amendment to any material term of the Superior Proposal, if any, resulting in the Company Notice of Adverse Recommendation or (2) with respect to any previous Company Adverse Recommendation Change, any material change in the principal stated rationale by the Company Board for such previous Company Adverse Recommendation Change, shall, in the case of either of the foregoing clauses (1) or (2), require a new Company Notice of Adverse Recommendation and a new three (3) Business Day period). The Company Board shall take into account any changes to the terms of this Agreement proposed by Parent in response to a Company Notice of Adverse Recommendation. Notwithstanding the foregoing, if fewer than three (3) Business Days remain before the then scheduled Expiration Date, the notice period with respect to the Company Board effecting a Company Adverse Recommendation Change pursuant to this Section 6.5(b) shall be no less than twenty-four (24) hours.

(c) In addition to the obligations of the Company set forth in Section 6.5(a) and Section 6.5(b), (i) the Company shall promptly advise Parent in writing no later than twenty-four (24) hours after it receives any Company Takeover Proposal or any inquiry that would reasonably be expected to lead to any Company Takeover Proposal and the material terms and conditions of any such Company Takeover Proposal or inquiry and (ii) the Company shall (A) keep Parent reasonably and promptly informed of the status of and any material change to any material term of any such Company Takeover Proposal or inquiry and (B) provide to Parent promptly after receipt or delivery thereof copies of all correspondence sent to or received by the Company and all information provided by the Company to any Person pursuant to such Company Takeover Proposal or inquiry. In addition, during the period from the date of this Agreement through the Offer Closing, the Company shall not terminate, amend, modify or waive any provision of any confidentiality or standstill agreement to which it is a party.

(d) Nothing contained in this Agreement shall prohibit the Company or the Company Board from (i) taking and disclosing to the Company’s shareholders a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act, or from issuing a “stop, look and listen” statement pending disclosure of its positions thereunder or (ii) from making any disclosure to the Company’s shareholders (including, without limitation, any amendments to its Schedule 14D-9 relating to a Company Adverse Recommendation Change) if, in the case of this clause (ii), in the good faith judgment of a majority of the Company Board, after consultation with outside counsel, failure to so disclose would be inconsistent with applicable Law.

Section 6.6 Shareholder Litigation. Prior to termination of this Agreement, the Company shall give Parent the opportunity to participate (at Parent’s expense) in the defense or settlement of any shareholder Litigation against the Company and its directors relating to the Transactions; provided, however, that no such settlement shall be agreed to without Parent’s prior written consent (such consent not to be unreasonably withheld, conditioned or delayed).

- 47 -

Section 6.7 Indemnification; Director and Officer Insurance.

(a) For not less than six (6) years from and after the Effective Time, Parent agrees to, and to cause the Surviving Corporation to, indemnify and hold harmless each person who is now, or has been at any time prior to the date hereof, a director or officer of the Company (the “Indemnified Parties”), to the same extent such Persons are indemnified as of the date of this Agreement against all claims, losses, liabilities, damages, judgments, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements, incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to acts or omissions occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent permitted by Law (including to the fullest extent authorized or permitted by any amendments to or replacements of the WBCA adopted after the date of this Agreement that increase the extent to which a corporation may indemnify its officers and directors). Each Indemnified Party will be entitled to advancement of expenses incurred in the defense of any such claim, action, suit, proceeding or investigation from each of Parent and the Surviving Corporation within ten (10) business days of receipt by Parent or the Surviving Corporation from the Indemnified Party of a request therefore; provided, that such Indemnified Party shall promptly reimburse Parent or the Surviving Corporation for any expenses so advanced if it is subsequently determined that such Person was not entitled to indemnification hereunder.

(b) For not less than six (6) years from and after the Effective Time, the Company Organizational Documents shall contain, and Parent shall cause the Company Organizational Documents of the Surviving Corporation to so contain, provisions no less favorable with respect to indemnification, advancement of expenses and exculpation of present and former directors and officers of the Company than are presently set forth in the Company Organizational Documents.

(c) Subject to the next sentence, the Company and the Surviving Corporation shall maintain, and Parent shall cause the Company and the Surviving Corporation to maintain for not less than six (6) years from and after the Effective Time, at no expense to the beneficiaries, the current policies of the directors’ and officers’ liability insurance maintained by the Company with respect to matters existing or occurring at or prior to the Effective Time (including the Transactions), so long as the annual premium therefor would not be in excess of 250% of the last annual premium paid prior to the Effective Time (such 250%, the “Maximum Premium”). If the Company’s existing insurance expires, is terminated or canceled during such six-year period or exceeds the Maximum Premium, the Surviving Corporation shall obtain, and Parent shall cause the Surviving Corporation to obtain, as much directors’ and officers’ liability insurance as can be obtained for the remainder of such period for an annualized premium not in excess of the Maximum Premium, on terms and conditions no less favorable to the Indemnified Parties than the Company’s existing directors’ and officers’ liability insurance. In lieu of the foregoing insurance coverage, Parent may after the Offer Closing Date instruct the Company to purchase prior to the Effective Time, a six-year prepaid “tail policy” on terms and conditions reasonably acceptable to Parent providing substantially equivalent benefits as the current policies of directors’ and officers’ liability insurance maintained by the Company with respect to matters existing or occurring at or prior to the Effective Time, covering without limitation the Transactions. If such prepaid “tail policy” has been obtained by the Company at the instruction of Parent prior to the Effective Time, Parent shall cause such policy to be maintained in full force and effect, for its full term, and cause all obligations thereunder to be honored by the Surviving Corporation.

- 48 -

(d) Parent shall pay all expenses, including reasonable attorneys’ fees, that may be incurred by any Indemnified Party in connection with their enforcement of their rights provided in this Section 6.7; provided, that such Indemnified Party is successful in enforcing such claim.

(e) Parent and Merger Sub agree that all rights to exculpation, indemnification and advancement of expenses for acts or omissions occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, now existing in favor of the current or former directors, officers or employees, as the case may be, of the Company as provided in the Company Organizational Documents shall survive the Merger and shall continue in full force and effect. The provisions of this Section 6.7 are intended to be in addition to the rights otherwise available by law, charter, statute, by-law or agreement, and shall operate for the benefit of, and shall be enforceable by, each of the Indemnified Parties, their heirs and their representatives. The obligations set forth in this Section 6.7 shall not be terminated, amended or otherwise modified in any manner that adversely affects any Indemnified Party and their heirs and representatives, without the prior written consent of such affected Indemnified Party or other Person.

(f) If the Surviving Corporation (or Parent) or any of its successors or assigns shall (i) consolidate with or merge into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfer all or substantially all of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Corporation shall assume all of the obligations of the Surviving Corporation (or Parent) set forth in this Section 6.7.

(g) Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to the Company for any of their respective directors, officers or other employees, it being understood and agreed that the indemnification provided for in this Section 6.7 is not prior to or in substitution for any such claims under such policies.

Section 6.8 Public Announcements. Each of the Company and Parent shall issue a press release announcing the execution of this Agreement in forms mutually agreed to by the Company and Parent. During the period between the date of this Agreement and the earlier of the Offer Closing and the termination of this Agreement in accordance with Section 8.1, the Company shall obtain the prior written consent of Parent, and Parent or Merger Sub shall obtain the prior written consent of the Company, prior to issuing any press releases with respect to any of the Transactions, except as may be required by Law or by obligations pursuant to any listing agreement with or rules of Nasdaq. In addition, the Company and Parent shall develop a joint communications strategy with respect to the matters set forth in Section 6.8 of the Company Disclosure Letter and each party shall ensure that, during the period between the date of this Agreement and the earlier of the Offer Closing and the termination of this Agreement in accordance with Section 8.1, all public statements and communications (including any communications that would require a filing under Rules 14d-2 or 14d-9 of the Exchange Act),

- 49 -

with analysts, members of the financial community or otherwise, with respect to any of the Transactions shall be consistent in all material respects with such joint communications strategy. Notwithstanding the foregoing, this Section 6.8 shall not apply with respect to any communications regarding any Company Takeover Proposal or Company Adverse Recommendation Change.

Section 6.9 Preparation of SEC Documents; Shareholders’ Meeting.

(a) As soon as practicable after the date hereof, and in any event no later than September 1, 2010, the Company shall prepare and file with the SEC, subject to the prior review and comment of Parent (it being understood that the Company shall consider in good faith any comments made by Parent), a proxy statement relating to the Company Shareholder Approval (such proxy statement, as amended or supplemented from time to time, the “Proxy Statement”). The Company shall use its reasonable best efforts to cause the Proxy Statement to be mailed to the Company’s shareholders as promptly as practicable after clearing comments received from the SEC. No filing of, or amendment or supplement to, the Proxy Statement will be made by the Company without providing Parent the reasonable opportunity to review and comment thereon. The Company will advise Parent promptly of any request by the SEC for amendment of the Proxy Statement or comments thereon and responses thereto or requests by the SEC for additional information. If at any time prior to the Effective Time any information relating to Parent or the Company, or any of their respective Affiliates, officers or directors, should become known to Parent or the Company which should be set forth in an amendment or supplement to the Proxy Statement, so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other parties hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by Law, disseminated to the shareholders of the Company.

(b) Each of the Company and Parent shall supply such information specifically for inclusion or incorporation by reference in the Proxy Statement necessary so that, at the date it is first mailed to the Company’s shareholders or at the time of the Company Shareholders’ Meeting, the Proxy Statement 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 are made, not misleading. Each of the parties hereto shall use their reasonable best efforts so that the Proxy Statement will comply as to form in all material respects with the requirements of the Exchange Act and the rules and regulations thereunder.

(c) The Company shall take all action necessary to duly call, give notice of, convene and hold a meeting of its shareholders as promptly as practicable for the purpose of obtaining the approval by the Company’s shareholders in accordance with the WBCA (the “Company Shareholders’ Meeting”). The Company shall ensure that the Company Shareholders’ Meeting is called, noticed, convened, held and conducted, and that all proxies solicited in connection with the Company Shareholders’ Meeting are solicited in compliance with applicable Law, the rules of Nasdaq and the Company Organizational Documents.

Section 6.12 Takeover Statutes. The Company and the Company Board shall take all actions necessary so that the restrictions contained in Chapter 23B.19 of the WBCA shall remain inapplicable to any and all of the Transactions.

(a) For a period of one (1) year following the Offer Closing, Parent shall or shall cause the Surviving Corporation to either (i) provide the employees of the Company and the Company Subsidiaries who are employed immediately prior to the Effective Time (the “Covered Employees”) who remain employed during such period by Parent, the Surviving Corporation or any of their respective Subsidiaries with compensation (excluding equity based compensation) that, taken as a whole, has a value not materially less, in the aggregate, than the compensation provided by the Company and the Company Subsidiaries to such employees as of the date hereof or (ii) provide or cause the Surviving Corporation (or, in such case, its successors or assigns) to provide Covered Employees who remain employed during such period by Parent, the Surviving Corporation or their respective Subsidiaries with compensation (excluding equity based compensation) that, taken as a whole, has a value not materially less, in the aggregate, than the compensation provided to similarly situated employees of Parent and its Subsidiaries from time to time. In addition, for a period of one (1) year following the Offer Closing, Parent shall or shall cause the Surviving Corporation provide or cause the Surviving Corporation (or, in such case, its successors or assigns) to provide Covered Employees who remain employed during such period by Parent, the Surviving Corporation or their respective Subsidiaries with benefits that, taken as a whole, have a value not materially less, in the aggregate, than the benefits provided to similarly situated employees of Parent and its Subsidiaries from time to time.

(b) For a period of one (1) year following the Offer Closing, Parent shall or shall cause the Surviving Corporation to provide Covered Employees whose employment is terminated by Parent or the Surviving Corporation with severance benefits in accordance with such employee’s individual compensatory agreement, if any, or, in the absence of any such agreement, in accordance with the Company’s severance policy in effect on the date hereof as set forth in Section 6.16 of the Company Disclosure Letter. Parent shall have no obligation and the Company shall take no action that would have the effect of requiring Parent or the Surviving Corporation to continue any specific plans (except with respect to existing individual compensatory agreements) or to continue the employment of any specific Person.

(c) For purposes of determining eligibility to participate in, and non-forfeitable rights under any employee benefit plan or arrangement of Parent or the Surviving Corporation or any of their respective Subsidiaries (including for purposes of vacation eligibility), but not for purposes of benefit accrual under any defined benefit pension plan of Parent or any of its Subsidiaries, Covered Employees shall receive service credit for service with the Company (and with any predecessor or acquired entities or any other entities for which the Company granted service credit) as if such service had been completed with Parent; provided, however, that such service need not be recognized to the extent that such recognition would result in any duplication of benefits for the same period of service.

- 52 -

(d) To the extent applicable, Parent shall or shall cause the Surviving Corporation and any of their respective Subsidiaries to waive, or use reasonable best efforts to cause its insurance carriers to waive, any pre-existing condition limitation on participation and coverage applicable to any Covered Employee or any of his or her covered dependents under any health or welfare plan of Parent or the Surviving Corporation or any of their respective Subsidiaries (a “New Plan”) in which such Covered Employee or covered dependent shall become eligible to participate after the Effective Time to the extent such Covered Employee or covered dependent was no longer subject to such pre-existing condition limitation under the corresponding Company Benefit Plan in which such Covered Employee or such covered dependent was participating immediately before he or she became eligible to participate in the New Plan. Parent shall or shall cause the Surviving Corporation or the relevant Subsidiary of either to provide each Covered Employee with credit for any co-payments and deductibles paid prior to the Effective Time and during the calendar year in which the Effective Time occurs under any Company Benefit Plan in satisfying any applicable co-payment and deductible requirements for such calendar year under any New Plan in which such Covered Employee participates after the Effective Time.

(e) Nothing in this Section 6.16 shall (i) confer any rights or remedies of any kind or description upon any Covered Employee or any other Person other than the Company and Parent and their respective successors and assigns, (ii) be construed as an amendment, waiver or creation of or limitation on the ability to terminate any Company Benefit Plan or Company Benefit Agreement or benefit plan or agreement of Parent or (iii) limit the ability of the Parent, the Company, the Surviving Corporation or any of their respective Subsidiaries to terminate the employment of any Covered Employee at any time.

- 57 -

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

the Company and Parent shall not have reached an agreement that the Offer or the Agreement be terminated, and the Agreement shall not have been terminated in accordance with its terms.

The foregoing conditions shall be in addition to, and not a limitation of, the rights of Parent and Merger Sub to extend, terminate and/or modify the Offer pursuant to the terms of the Agreement.

The foregoing conditions are for the benefit of Parent and Merger Sub, may be asserted by Parent or Merger Sub regardless of the circumstances giving rise to any such conditions and may be waived by Parent or Merger Sub in whole or in part at any time and from time to time in their sole discretion (except for the Minimum Tender Condition (defined herein)), in each case, subject to the terms of the Agreement and the applicable rules and regulations of the SEC. The failure by Parent or Merger Sub at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right and each such right shall be deemed an ongoing right which may be asserted at any time and from time to time.
