The Merger shall become effective upon the date and time of the filing of the Certificate of Merger with the Secretary of State of the State of Delaware or such other date and time as may be mutually agreed upon by Parent and the Company and set forth in the Certificate of Merger (the "Effective Time").

Β Β Β Β 1.4Β Β Certificate of Incorporation and Bylaws.Β Β Unless otherwise determined by Parent and the Company prior to the Effective Time:

    Β Β Β Β (a)Β the Certificate of Incorporation of the Surviving Corporation shall be the certificate of incorporation of the Company as in effect at the Effective Time;

    Β Β Β Β (b)Β the Bylaws of the Surviving Corporation shall be the Bylaws of the Company as in effect immediately prior to the Effective Time; and

    Β Β Β Β (c)Β the directors of the Surviving Corporation immediately after the Effective Time shall be the respective individuals who are directors of Merger Sub immediately prior to the Effective Time.

Β Β Β Β 1.5Β Β Directors and Officers; Headquarters.Β Β 

    Β Β Β Β (a)Β Prior to the Effective Time, Parent shall take such action so that, from and after the Effective Time, until duly changed in compliance with applicable Legal Requirements and the Certificate of Incorporation and Bylaws of Parent, the Board of Directors of Parent shall consist of seven members as set forth in ExhibitΒ C.

    Β Β Β Β (b)Β Parent shall take such action so that, upon the Effective Time, the following persons, subject to availability, shall hold the following positions with Parent: Xx.Β Xxxxx Xxxxxxxxx shall be the Chairman of the Board of Directors and Xx.Β Xxxxxx Xxxxxxxxx shall be the Chief Executive Officer.

    Β Β Β Β (d)Β From and after the Effective Time, the location of the headquarters and principal executive offices of Parent and the Surviving Corporation shall each be that of the headquarters and principal executive offices of Parent as of the date of this Agreement.

Β Β Β Β 1.6Β Β Conversion of Shares.Β Β 

    Β Β Β Β (a)Β At the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Merger Sub, the Company or any stockholder of the Company:

      Β Β Β Β Β (i)Β subject to Sections 1.6(b), 1.6(c) and 1.6(d), each share of Company Common Stock, other than Excluded Shares, then outstanding shall be converted into the right to receive 1.254 shares (the "Exchange Ratio") of Parent Common Stock; provided, however, that if Parent is required to issue more than 16,081,759 shares of Parent Common Stock in the Merger, the Exchange Ratio shall be the quotient (rounded to the nearest thousandth) obtained by dividing (A)Β 16,081,759 by (B)Β the number of shares of Company Common Stock outstanding immediately prior to the Effective Time;

      Β Β Β Β (ii)Β each share of the Common Stock, $0.001 par value per share, of Merger Sub then outstanding shall be converted into one share of Common Stock of the Surviving Corporation; and

      Β Β Β Β (iii)Β any Excluded Shares shall be cancelled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor.

    Β Β Β Β (b)Β If, between the date of this Agreement and the Effective Time, the outstanding shares of Company Common Stock or Parent Common Stock are changed into a different number or class of shares by reason of any stock split, stock dividend, reverse stock split, reclassification, recapitalization or other similar transaction, then the Exchange Ratio shall be appropriately adjusted.

    Β Β Β Β (c)Β If any shares of Company Common Stock outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option, risk of forfeiture or other condition under any applicable restricted stock purchase agreement or other agreement with the Company or under which the Company has any rights, then the shares of Parent Common Stock issued in exchange for such shares of Company Common Stock will also be unvested and subject to the same repurchase option, risk of forfeiture or other condition, and the certificates representing such shares of Parent Common Stock may accordingly be marked with appropriate legends. The Company shall take all action that may be necessary to ensure that, from and after the Effective Time, Parent is entitled to exercise any such repurchase option or other right set forth in any such restricted stock purchase agreement or other agreement.

    Β Β Β Β (d)Β No fractional shares of Parent Common Stock shall be issued in connection with the Merger, and no certificates or scrip for any such fractional shares shall be issued. Any holder of Company Common Stock who would otherwise be entitled to receive a fraction of a share of Parent Common Stock (after aggregating all fractional shares of Parent Common Stock issuable to such holder) shall, in lieu of such fraction of a share and upon surrender of such holder's Company Stock Certificate(s) (as defined in SectionΒ 1.7), be paid in cash the dollar amount (rounded to the nearest whole cent), without interest, determined by multiplying such fraction by the closing price of a share of Parent Common Stock as reported on The Nasdaq National Market on the date the Merger becomes effective.

Β Β Β Β 1.7Β Β Closing of the Company's Transfer Books.Β Β At the Effective Time: (a)Β all shares of Company Common Stock outstanding immediately prior to the Effective Time shall automatically be canceled and retired and shall cease to exist, and all holders of certificates representing shares of Company Common Stock that were outstanding immediately prior to the Effective Time shall cease to have any rights as stockholders of the Company; and (b)Β the stock transfer books of the Company shall be closed

3

with respect to all shares of Company Common Stock outstanding immediately prior to the Effective Time. No further transfer of any such shares of Company Common Stock shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any shares of Company Common Stock (a "Company Stock Certificate") is presented to the Exchange Agent (as defined in SectionΒ 1.8) or to the Surviving Corporation or Parent, such Company Stock Certificate shall be canceled and shall be exchanged as provided in SectionΒ 1.8.

Β Β Β Β 1.8Β Β Exchange of Certificates.Β Β 

    Β Β Β Β (a)Β On or prior to the Closing Date, Parent shall select a reputable bank or trust company to act as exchange agent in the Merger (the "Exchange Agent"). Within 15 business days after the Effective Time, Parent shall deposit with the Exchange Agent, for the benefit of the holders of shares of the Company Common Stock, (i)Β certificates representing the shares of Parent Common Stock issuable pursuant to this SectionΒ 1, and (ii)Β cash sufficient to make payments in lieu of fractional shares in accordance with SectionΒ 1.6(d). The shares of Parent Common Stock and cash amounts so deposited with the Exchange Agent, together with any dividends or distributions with respect to such shares, are referred to collectively as the "Exchange Fund."

    Β Β Β Β (b)Β As soon as reasonably practicable after the Effective Time, the Exchange Agent will mail to the record holders of Company Stock Certificates (i)Β a letter of transmittal in customary form and containing such provisions as Parent and the Company may reasonably specify (including a provision confirming that delivery of Company Stock Certificates shall be effected, and risk of loss and title to Company Stock Certificates shall pass, only upon delivery of such Company Stock Certificates to the Exchange Agent), and (ii)Β instructions for use in effecting the surrender of Company Stock Certificates in exchange for certificates representing Parent Common Stock (plus cash in lieu of fractional shares, if any, of Parent Common Stock). Upon surrender of a Company Stock Certificate to the Exchange Agent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably required by the Exchange Agent or Parent, (1)Β the holder of such Company Stock Certificate shall be entitled to receive in exchange therefor a certificate representing the number of whole shares of Parent Common Stock that such holder has the right to receive pursuant to the provisions of SectionΒ 1.6 (and cash in lieu of any fractional share of Parent Common Stock), and (2)Β the Company Stock Certificate so surrendered shall be immediately canceled. Until surrendered as contemplated by this SectionΒ 1.8 each Company Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive shares of Parent Common Stock (and cash in lieu of any fractional share of Parent Common Stock) as contemplated by SectionΒ 1. If any Company Stock Certificate shall have been lost, stolen or destroyed, Parent may, in its discretion and as a condition precedent to the issuance of any certificate representing Parent Common Stock, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an appropriate affidavit and to deliver a bond (in such sum as Parent may reasonably direct) as indemnity against any claim that may be made against the Exchange Agent, Parent or the Surviving Corporation with respect to such Company Stock Certificate, and, in such case, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Company Stock Certificates the shares of Parent Common Stock and any cash in lieu of fractional shares.

    Β Β Β Β (c)Β No dividends or other distributions declared or made with respect to Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Company Stock Certificate with respect to the shares of Parent Common Stock that such holder has the right to receive in the Merger until such holder surrenders such Company Stock Certificate in accordance with this SectionΒ 1.8 (at which time such holder shall be entitled, subject to the effect of applicable escheat or similar laws, to receive all such dividends and distributions, without interest).

4

    Β Β Β Β (d)Β Any portion of the Exchange Fund that remains undistributed to holders of Company Stock Certificates as of the date 180Β days after the Effective Time shall be delivered to Parent upon demand, and any holders of Company Stock Certificates who have not theretofore surrendered their Company Stock Certificates in accordance with this SectionΒ 1.8 shall thereafter look only to Parent for satisfaction of their claims for Parent Common Stock, cash in lieu of fractional shares of Parent Common Stock and any dividends or distributions with respect to Parent Common Stock.

    Β Β Β Β (e)Β Each of the Exchange Agent, Parent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Company Common Stock such amounts as may be required to be deducted or withheld therefrom under the Code or any provision of state, local or foreign tax law or under any other applicable Legal Requirement. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

    Β Β Β Β (f)Β Β Neither Parent nor the Surviving Corporation shall be liable to any holder or former holder of Company Common Stock or to any other Person with respect to any shares of Parent Common Stock (or dividends or distributions with respect thereto), or for any cash amounts, delivered to any public official pursuant to any applicable abandoned property law, escheat law or similar Legal Requirement.

Β Β Β Β 1.9Β Β No Appraisal Rights.Β Β In accordance with SectionΒ 262 of the DGCL, no appraisal rights shall be available to the holders of shares of Company Common Stock in connection with the Merger.

Β Β Β Β 1.10Β Β Tax Consequences.Β Β For federal income tax purposes, the Merger is intended to constitute a reorganization within the meaning of SectionΒ 368 of the Code. The parties to this Agreement hereby adopt this Agreement as a "plan of reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Treasury Regulations.

Β Β Β Β 1.11Β Β Further Action.Β Β If, at any time after the Effective Time, any further action is determined by Parent to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of Merger Sub and the Company, the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Merger Sub, in the name of the Company and otherwise) to take such action.

SECTION 2.Β Β Representations and Warranties of the Company

This Agreement constitutes the legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, subject to (i)Β laws of general application relating to bankruptcy, insolvency and the relief of debtors, and (ii)Β rules of law governing specific performance, injunctive relief and other equitable remedies.
