THE OFFER AND MERGER

Section 1.1 The Offer . (a) Provided that this Agreement shall not have been terminated in accordance with Section 8.1 and none of the events or conditions set forth in

Annex I hereto shall have occurred and be continuing and not have been waived by Parent or Purchaser, as promptly as reasonably practicable and, in any event, within ten (10) Business Days of the date of this Agreement, the Purchaser shall commence (within the meaning of Rule 14d-2 under the U.S. Securities Exchange Act of 1934, as amended (together with the rules and regulations thereunder, the “ Exchange Act ”)) the Offer to purchase for cash all Shares at the Offer Price. The obligations of the Purchaser to accept for payment and to pay for any Shares validly tendered on or prior to the expiration of the Offer and not withdrawn shall be subject to (i) there being validly tendered and not withdrawn prior to the expiration of the Offer that number of Shares which represents a majority of the Shares outstanding on a fully-diluted basis (the “ Minimum Condition ”) and (ii) the other conditions set forth in Annex I hereto. Subject to the prior satisfaction or waiver by Parent or the Purchaser of the Minimum Condition and the other conditions of the Offer set forth in Annex I hereto, the Purchaser shall, in accordance with the terms of the Offer, consummate the Offer and accept for payment and pay for all Shares validly tendered and not withdrawn pursuant to the Offer promptly after expiration of the Offer, which shall initially be the 20th Business Day following the commencement of the Offer; provided , however , that (x) if on the initial expiration date of the Offer or on any subsequent scheduled expiration date of the Offer (as extended in accordance with this Agreement), all conditions to the Offer shall not have been satisfied or waived, the Purchaser may, from time to time, in its sole discretion, extend the Offer for such period as the Purchaser may determine; provided , however , that if on the initial expiration date of the Offer the conditions to the Offer set forth in paragraphs (c), (d) and (e) of Annex I hereto shall each be satisfied (or, in the case of paragraphs (d) and (e), if any such breach or failure to comply that has caused such non-satisfaction of the condition is objectively curable within ten (10) Business Days) but any other condition to the Offer shall not have been satisfied or waived, Purchaser shall be obligated to extend the Offer for one or more periods of time of up to ten (10) Business Days each (or such longer period as Purchaser may agree in writing) until such conditions have been satisfied or waived; provided , that Purchaser shall not be required to extend the Offer beyond the date that is thirty (30) Business Days following the initial expiration of the Offer; (y) the Purchaser may, in its sole discretion, extend the Offer for any period required by any rule, regulation, interpretation or position of the SEC or the staff thereof applicable to the Offer; and (z) the Purchaser may, in its sole discretion, provide a “subsequent offering period” for three (3) to twenty (20) Business Days to acquire outstanding untendered Shares in accordance with Rule 14d-11 under the Exchange Act if the Minimum Condition and all of the other conditions set forth in Annex I hereto are satisfied or waived, but the number of Shares that have been validly tendered and not withdrawn in the Offer and accepted for payment, together with any Shares then owned by Parent, is less than 90% of the outstanding Shares. Purchaser shall not extend the Offer following the termination of this Agreement. In addition, the Purchaser may increase the Offer Price and extend the Offer to the extent required by Law in connection with such increase, in each case in its sole discretion and without the Company’s consent, but Purchaser and Parent shall not, without the prior written consent of the Company, (A) decrease the Offer Price (as it may have been increased hereunder) or change the form of consideration payable in the Offer, (B) decrease the number of Shares sought pursuant to the Offer, (C) amend or waive the Minimum Condition, (D) add to the conditions to the Offer set forth in Annex I hereto or modify such conditions in a manner adverse to the holders of Shares, (E) extend the Offer, except as permitted by this Section 1.1(a) or (F) make any other change in the terms or conditions of the Offer that is adverse to the holders of Shares.

such expiration date may be extended and re-extended in accordance with this Agreement), unless this Agreement is validly terminated in accordance with Article VIII .

The Company agrees to cause the Schedule 14D-9 to be filed with the SEC and, subject to the Purchaser’s compliance with Section 1.1(a) , disseminated to holders of Shares as required by and in accordance with applicable U.S. federal securities laws.

Section 1.3 Directors . Promptly upon the acceptance for payment of any Shares by Parent or the Purchaser or any of their affiliates pursuant to the Offer (the “ Acceptance Time ”) and from time to time thereafter, Parent shall be entitled, subject to Section 1.3(b) , to elect or designate such number of directors, rounded up to the next whole number, on the Company Board of Directors as is equal to the product of (i) the total number of directors on the Company Board of Directors (giving effect to the directors elected or designated by Parent pursuant to this Section 1.3 ) multiplied by (ii) the quotient obtained by dividing the aggregate number of Shares beneficially owned by the Purchaser, Parent and any of their affiliates by the total number of Shares then outstanding (on a fully-diluted basis). The Company shall, upon Parent’s request, either use its reasonable best efforts to promptly increase the size of the Company Board of Directors, or use its reasonable best efforts to promptly secure the resignations of such number of its incumbent directors, or both, as is necessary to enable Parent’s designees to be so elected or designated to the Company’s Board of Directors, and shall use its reasonable best efforts to take all actions necessary to cause Parent’s designees to be so elected or designated at such time. At such time, the Company shall, upon Parent’s request, also use its reasonable best efforts to cause persons elected or designated by Parent to constitute the same percentage (rounded up to the next whole number) as is on the Company Board of Directors of each committee of the Company Board of Directors, subject to appropriate qualification. The Company’s obligations under this Section 1.3 shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 thereunder. The Company shall promptly take all actions required pursuant to such Section 14(f) and Rule 14f-1 in order to fulfill its obligations under this Section 1.3 , including, but not limited to, mailing to stockholders (together with the Schedule 14D-9) such information as is required by such Section 14(f) and Rule 14f-1 to enable Parent’s designees to be elected or designated to the Company Board of Directors. Parent or the Purchaser shall supply the Company with the information and consents with respect to either of them and their nominees, officers, directors and affiliates to the extent required by such Section 14(f) and Rule 14f-1.

(b) In the event that Parent’s designees are elected or designated to the Board of Directors of the Company, then, until the Effective Time, the Company shall cause the Board of Directors of the Company to have at least three (3) directors who are (i) directors on the date of this Agreement, (ii) independent directors for purposes of the continued listing requirements of the Nasdaq Global Market (“ NASDAQ ”) and (iii) reasonably satisfactory to Parent (such directors, the “ Independent Directors ”); provided , however , that, if any Independent Director is unable to serve due to death or disability or any other reason (including as a result of removal for cause pursuant to the last sentence of this Section 1.3(b) ), the remaining Independent Directors (or Independent Director) shall be entitled to elect or designate another individual (or individuals) who serve(s) as a director (or directors) on the date of this Agreement (provided that no such individual is an employee of the Company) to fill the vacancy, and such director (or directors) shall be deemed to be an Independent Director (or Independent Directors) for purposes of this Agreement. If no Independent Director remains prior to the Effective Time, a majority of the members of the Board of Directors of the Company at the time of the execution of this Agreement shall be entitled to designate three persons to fill such vacancies; provided that such individuals shall not be employees or officers of the Company, Parent or the Purchaser and shall be reasonably satisfactory to Parent, and such persons shall be deemed Independent Directors for purposes of this Agreement. Following the Acceptance Time and prior to the Effective Time, Parent and Purchaser shall not cause any amendment or termination of this Agreement, any extension by the Company of the time for the performance of any of the obligations or other acts

5

of Purchaser or Parent or waiver of any of the Company’s rights under this Agreement or other action adversely affecting the rights of the Company Stockholders (other than Parent or the Purchaser), to be effected without the affirmative vote of a majority of the Independent Directors. Following the Acceptance Time and prior to the Effective Time, neither Parent nor Purchaser shall take any action to remove any Independent Director unless the removal shall be for cause.

Section 1.4 Top-Up Option .

(a) Subject to the requirements of Section 1.4(b) , the Company hereby grants to Parent and the Purchaser an irrevocable option (the “ Top-Up Option ”) to purchase from the Company that number (but not less than that number) of shares of Company common stock (the “ Top-Up Option Shares ”) equal to the number of shares of Company common stock that, when added to the Shares owned by Parent and Purchaser immediately following consummation of the Offer, shall constitute one share more than 90% of the Shares outstanding (after giving effect to the issuance of the Top-Up Option Shares) for consideration per Top-Up Option Share equal to the Offer Price.

(b) The Top-Up Option shall be exercisable only one time and only after the purchase of and payment for Shares pursuant to the Offer by Parent or the Purchaser as a result of which Parent and the Purchaser own beneficially at least 80% of the Shares outstanding. The Top-Up Option shall not be exercisable if the number of shares of Company common stock subject thereto exceeds the number of authorized shares of Company common stock available for issuance and not otherwise reserved for issuance by the Company.

(c) In the event that Parent or Purchaser wishes to exercise the Top-Up Option, Parent or the Purchaser shall give the Company written notice specifying the number of shares of Company common stock that are or will be owned by Parent and the Purchaser immediately following consummation of the Offer and specifying a place and a time for the closing of the purchase (which shall not be more than three (3) Business Days after delivery of such notice) and certifying that as promptly as practicable following such exercise the Purchaser and Parent intend to (and Purchaser and Parent shall as promptly as practicable after such exercise) consummate the Merger in accordance with Section 253 of the DGCL as contemplated by Section 1.11 . The Company shall, as soon as practicable following receipt of such notice, deliver written notice to the Purchaser specifying the number of Top-Up Shares. At the closing of the purchase of the Top-Up Shares, the purchase price owing upon exercise of the Top-Up Option that equals the product of (i) the number of shares of Company common stock purchased pursuant to the Top-Up Option, multiplied by (ii) the Offer Price, shall be paid to the Company, at the election of Parent and Purchaser, in cash (by wire transfer or cashier’s check) or by delivery of a promissory note having full recourse to Parent.

(d) The Top-Up Option may not be exercised if any provision of applicable Law or any judgment, injunction, order or decree of any Governmental Entity shall prohibit, or require any action, consent, approval, authorization or permit of, or action by, or filing with or notification to, any Governmental Entity or the Company Stockholders in connection with the exercise of the Top-Up Option or the delivery of the Top-Up Shares in respect of such exercise, which action, consent, approval, authorization or permit, action, filing or notification has not theretofore been obtained or made, as applicable.

6

(e) Each of Parent and the Purchaser understands that the Shares that Purchaser may acquire upon exercise of the Top-Up Option will not be registered under the Securities Act, and will be issued in reliance upon an exemption thereunder for transactions not involving a public offering. Parent and the Purchaser represent and warrant to the Company that the Purchaser is, and will be upon exercise of the Top-Up Option, an “accredited investor” (as defined in Rule 501 of Regulation D promulgated under the Securities Act). The Purchaser agrees that the Top-Up Option and the Top-Up Shares to be acquired upon exercise thereof are being and will be acquired for the purpose of investment and not with a view to or for resale in connection with any distribution thereof within the meaning of the Securities Act. Any certificates evidencing Top-Up Shares may include any legends required by applicable securities laws.

Section 2.2 Paying Agent .

(a) Prior to the Effective Time, Parent shall designate an agent reasonably acceptable to the Company (the “ Paying Agent ”) for the holders of Shares in connection with the Merger and to receive the funds to which holders of Shares shall become entitled pursuant to Section 2.1(c) . At the Effective Time, Parent shall deposit, or shall cause the Surviving Corporation to deposit, with the Paying Agent cash in an amount sufficient to pay the aggregate Merger Consideration and Option Consideration required to be paid pursuant to Section 2.1(c) . Such funds shall be invested by the Paying Agent as directed by Parent or the Surviving Corporation, in its sole discretion, pending payment thereof by the Paying Agent to the holders of the Shares; provided that such investments shall be in obligations of or guaranteed by the United States of America, in commercial paper obligations rated A-1 or P-1 or better by Moody’s Investor Services, Inc. or Standard & Poor’s Corporation, respectively, or in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $1 billion and no such investment or loss thereon shall effect the amounts payable to the Company’s stockholders pursuant to this Article II . Earnings from such investments shall be the sole and exclusive property of Parent and the Surviving Corporation, and no part of such earnings shall accrue to the benefit of holders of Shares.

(b) Promptly after the Effective Time (and in any event within three (3) Business Days thereafter), the Paying Agent shall mail to each holder of record of Shares (the “ Certificates ”), whose Shares were converted pursuant to Section 2.1 into the right to receive the Merger Consideration (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 which shall be in customary form and shall include customary provisions with respect to delivery of an “agent’s message” with respect to shares held in book-entry form) and (ii) instructions for effecting the surrender of the Certificates in exchange for payment of 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, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration for each Share formerly represented by such Certificate and the Certificate so surrendered shall forthwith be cancelled. If payment of the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition precedent of payment that (x) the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer, and (y) the Person requesting such payment shall have paid any transfer and other taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate surrendered or shall have established to the satisfaction of the Surviving Corporation that such tax either has been paid or is not required to be paid. Until surrendered as contemplated by this Section 2.2 , each Certificate shall be deemed after the Effective Time to represent only the right to receive the Merger Consideration, without interest thereon.

(c) At the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of Shares on the

10

records of the Company. From and after the Effective Time, the holders of Certificates evidencing ownership of Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares, except as otherwise provided for herein or by applicable Law. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in this Article II .
