ARTICLE I

THE MERGER

1.1 The Merger. At the Effective Time, and subject to and upon the terms and conditions of this Agreement and the applicable provisions of Delaware Law, Merger Sub shall merge with and into Company. Company shall be the Surviving Corporation in the Merger and shall continue its corporate existence under the laws of the State of Delaware. Upon consummation of the Merger, the separate corporate existence of Merger Sub shall terminate.

1.2 Closing. The Closing shall take place as soon as practicable, and in any event not later than two (2) Business Days after the satisfaction or waiver of each of the conditions set forth in Article VII hereof or at such other time as the parties hereto may agree (the “Closing Date”). The Closing shall take place at the offices of ▇▇▇▇▇▇ ▇▇▇▇ Nemerovski ▇▇▇▇▇▇ ▇▇▇▇ & Rabkin, A Professional Corporation, ▇ ▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, or at such other location as the parties hereto may agree in writing.

1.3 Effective Time. Prior to the Closing, Parent and Company shall prepare, and on the Closing Date the parties shall file, a certificate of merger (the “Certificate of Merger”) with the Secretary of State of the State of Delaware in accordance with the relevant provisions of Delaware Law. The Merger shall become effective at the Effective Time as set forth in the Certificate of Merger which shall be filed with the Secretary of State of the State of Delaware on the Closing Date (the time the Merger becomes effective being the “Effective Time”).

1.4 Effects of the Merger. At and after the Effective Time, the Merger shall have the effects set forth in the applicable provisions of the Delaware Law. Without limiting the generality of the foregoing, at the Effective Time, all the property, rights, privileges, powers and franchises of Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

1.5 Certificate of Incorporation; By-Laws; Directors and Officers. Unless otherwise determined by Merger Sub before the Effective Time, at the Effective Time:

(a) The Certificate of Incorporation of Merger Sub, as in effect immediately before the Effective Time, shall be the Certificate of Incorporation of the Surviving Corporation.

(b) The By-Laws of Merger Sub, as in effect immediately before the Effective Time, shall be the By-Laws of the Surviving Corporation.

(c) The directors of Merger Sub immediately before the Effective Time will be the initial directors of the Surviving Corporation, and, except as Merger Sub may otherwise notify Company in writing prior to the Effective Time, the officers of Company immediately before the Effective Time will be the initial officers of the Surviving Corporation.

1.6 Conversion of Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, Company or the stockholders of any of the foregoing, the shares of stock of the constituent corporations shall be converted as follows:

(a) Common Stock of Merger Sub. Each share of common stock, par value $0.01 per share, of Merger Sub (the “Merger Sub Common Stock”) 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 $0.01 per share, of the Surviving Corporation.

(b) Cancellation of Treasury Stock and Parent and Merger Sub-Owned Company Common Stock. Each issued and outstanding share of common stock, par value $0.001 per share, of Company (the “Company Common Stock”) that is owned by Parent, Merger Sub or any other wholly owned subsidiary of Parent or held in the treasury of Company (collectively, the “Excluded Shares”) shall automatically be canceled and retired and shall cease to exist, and no cash, Company Common Stock or other consideration shall be delivered or deliverable in exchange therefor.

(c) Conversion or Retention of Company Common Stock. Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than Excluded Shares and Dissenting Shares and subject to Section 1.8 with respect to Restricted Stock and Escrowed Shares) shall be converted into the right to receive an amount equal to $18.50 in cash (the “Merger Consideration”) upon surrender of the certificate representing such share of Company Common Stock following the Merger in the manner set forth in Section 1.7. All shares of Company Common Stock converted into Merger Consideration pursuant to this Section 1.6(c) shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and each certificate previously representing any such shares of Company Common Stock shall thereafter represent the right to receive with respect to each underlying share of Company Common Stock the Merger Consideration. If, prior to the Effective Time, the outstanding shares of Company Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar change in capitalization, then an appropriate and proportionate adjustment shall be made to the Merger Consideration.

(d) Dissenting Shares. Holders of Dissenting Shares shall have those rights, but only those rights, of holders who perfect their appraisal rights under Section 262 of the Delaware Law. Company shall give Parent prompt notice of any demand, purported demand, objection, notice, petition, or other communication received from stockholders or provided to stockholders by Company with respect to any Dissenting Shares or shares claimed to be Dissenting Shares, and Parent shall have the right to participate in all negotiations

and proceedings with respect to such shares. Payment of any amount payable to the holders of Dissenting Shares shall be the obligation of Company. However, Company agrees that, without the prior written consent of Parent, it shall not voluntarily make any payment with respect to, or settle or offer to settle, any demand or purported demand respecting such shares.

1.7 Exchange of Certificates.

(a) Exchange Agent. At or prior to the Effective Time, Parent shall appoint a bank or trust company to act as exchange agent (the “Exchange Agent”) for the payment of the Merger Consideration. Immediately after the Effective Time, Parent shall deposit or cause the Surviving Corporation to deposit with the Exchange Agent, for the benefit of the holders of shares of Company Common Stock, for exchange in accordance with this Article Article I, an amount of cash equal to the product of the Merger Consideration and the total number of outstanding shares of Company Common Stock (such product, the “Aggregate Merger Consideration,” and such aggregate cash being deposited, the “Exchange Fund”). The Exchange Agent shall, pursuant to irrevocable instructions of the Surviving Corporation, make payments of the Merger Consideration out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose. Any and all interest earned on the Exchange Fund shall be paid to Parent.

(b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each holder of record of a certificate or certificates, or an electronic book entry position in lieu of a physical certificate or certificates, that immediately prior to the Effective Time represented outstanding shares of Company Common Stock (a “Certificate”) whose shares were converted into the right to receive Merger Consideration pursuant to Section 1.6, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass to the Exchange Agent, only upon delivery of the Certificates to the Exchange Agent, and shall be in such form and have such other provisions as Parent may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Upon surrender of a Certificate for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration payable in respect of the shares of Company Common Stock theretofore represented by such Certificate pursuant to the provisions of this Article I, and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Company Common Stock that is not registered in the transfer records of Company, payment may be made to a person other than the person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment shall pay any transfer or other taxes required by reason of the payment to a person other than the registered holder of such Certificate or establish to the satisfaction of Parent that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 1.7, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration as contemplated by this Section 1.7. No interest shall be paid or accrue on any cash payable upon surrender of any Certificate.

(c) No Further Ownership Rights in Company Common Stock Exchanged For Cash. The Merger Consideration paid upon the surrender for exchange of Certificates representing shares of Company Common Stock in accordance with the terms of this Article I shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Company Common Stock exchanged for cash theretofore represented by such Certificates.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of the Certificates for six months after the Effective Time shall be delivered to the Surviving Corporation and any holders of shares of Company Common Stock prior to the Merger who have not theretofore complied with this Article I shall thereafter look only to the Surviving Corporation and only as general creditors thereof for payment of the Merger Consideration.

(e) No Liability. None of Parent, Merger Sub, the Surviving Corporation, Company or the Exchange Agent, or any employee, officer, director, agent or affiliate thereof, shall be liable to any Person in respect of any cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate has not been surrendered prior to five years after the Effective Time (or immediately prior to such earlier date on which the Merger Consideration would otherwise escheat to or become the property of any Governmental Entity), any such cash in respect of such Certificate shall, to the extent permitted by applicable law, become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto.

(f) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund, as directed by the Surviving Corporation, on a daily basis. Any interest and other income resulting from such investments shall be paid to Parent. To the extent that there are losses with respect to such investments, or the Exchange Fund diminishes for other reasons below the level required to make prompt payments of the Merger Consideration to all of the holders of Company Common Stock as contemplated hereby, Parent shall promptly replace or restore the portion of the Exchange Fund lost through investments or other events so as to ensure that the Exchange Fund is, at all times, maintained at a level sufficient to make such payments.

(g) Withholding Rights. The Surviving Corporation or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock such amounts as the Surviving Corporation or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended and the treasury regulations promulgated thereunder (the “Code”), or any provision of state, local or foreign Tax law. To the extent that amounts are so deducted and withheld by the Surviving Corporation or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of which such deduction and withholding was made by the Surviving Corporation or the Exchange Agent.

(h) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such Person of a bond in such reasonable amount as the Surviving Corporation may require as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect thereof, pursuant to this Agreement.

1.8 Equity Incentive Plans and Related Matters.

(a) Company Options.

(i) At the Effective Time, each Company Option that is then outstanding with an exercise price less than the Merger Consideration (an “In-the-Money Option”) shall be assumed and converted into the right to receive an amount in cash equal to the product of (i) the total number of shares of Company Common Stock subject to such In-the-Money Option multiplied by (ii) the excess, if any, of the Merger Consideration over the exercise price per share of Company Common Stock, with such amount rounded down to the nearest whole cent (the “Option Consideration”).

(ii) Immediately prior to the Effective Time, each Company Option that is then outstanding with an exercise price greater than the Merger Consideration (an “Underwater Option”) shall become fully vested and exercisable. At the Effective Time, each Underwater Option shall terminate.

(iii) Parent shall, or shall cause the Company to: (x) pay to holders of In-the-Money Options that immediately prior to the Effective Time were vested, the Option Consideration less applicable Taxes required to be withheld with respect to such payment related to such vested In-the-Money Options promptly after the Effective Time and (y) pay to holders of In-the-Money Options that immediately prior to the Effective Time were unvested, the Option Consideration less applicable Taxes required to be withheld with respect to such payment over time and without interest in accordance with the vesting schedule set forth in the agreement evidencing such In-the-Money Options.

(iv) Subject to the foregoing provisions of this Section 1.8(a), each In-the-Money Option so assumed by Parent shall continue to have, and be subject to, the same terms and conditions set forth in the agreement evidencing such option and the applicable Company Equity Incentive Plan immediately prior to the Effective Time, including provisions with respect to vesting, except that each In-the-Money Option shall be converted into the right to receive the Option Consideration as described in this Section 1.8(a), and except that payment of the Option Consideration shall be made promptly after the Effective Time or promptly after the applicable vesting dates, as described in this Section 1.8(a), and not upon exercise of the assumed In-the-Money Options by the holder.

(v) Prior to the Effective Time, the Company shall provide notice (in a form reasonably satisfactory to Parent) to each holder of an outstanding Company Option describing the treatment of the Company Option in accordance with this Section 1.8(a).

(b) Restricted Stock. At the Effective Time, the unvested shares of Restricted Stock that are then outstanding shall be converted into the Merger Consideration; provided, however, that the Merger Consideration issuable in exchange therefor shall remain subject to the terms and conditions of the applicable Company Equity Incentive Plan or other agreements by which such shares of Restricted Stock were issued or are otherwise subject, including the vesting schedule. Parent shall, or shall cause the Company to, pay to holders of Restricted Stock the Merger Consideration less applicable Taxes required to be withheld with respect to such payment over time and without interest in accordance with the vesting schedule set forth in the agreement by which such shares of Restricted Stock were issued or are otherwise subject. Prior to the Effective Time, the Company shall provide notice (in a form reasonably satisfactory to Parent) to each holder of Restricted Stock describing the treatment of the Restricted Stock in accordance with this Section 1.8(b).

(c) Employee Stock Purchase Plan. Prior to the Effective Time, the Board of Directors shall terminate Company’s Employee Stock Purchase Plan and return all cash accumulated in each participant’s account to such participants.

(d) Escrowed Shares. At the Effective Time, the Escrowed Shares that are then outstanding shall be converted into the Merger Consideration; provided that for the avoidance of doubt, such conversion and the consummation of the Merger shall not affect in any manner the Escrow Agreement or the rights and obligations of the parties thereto under the Escrow Agreement. Without limiting the generality of the foregoing, the rights of the holders of the Escrowed Shares to obtain the Merger Consideration for their Escrowed Shares pursuant to Section 1.7 or otherwise shall be subject to the rights of the Company against the Escrowed Shares under the Escrow Agreement (and the Company’s right to the Merger Consideration into which the Escrowed Shares have been converted).

(e) Other Actions. At or prior to the Effective Time, Company’s Board of Directors shall adopt any resolutions and take any actions which are necessary to effectuate this Section 1.8. At the Effective Time, the Company agrees to effect the termination of the Company’s Equity Incentive Plans.

1.9 Taking of Necessary or Further Action. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of Company and Merger Sub, Company, Parent and Merger Sub shall cause their respective officers to take all such lawful and necessary action, so long as such action is not inconsistent with this Agreement.
