          (b) The Top-Up Option shall be exercisable once in whole and not in part during the twenty (20) Business Day period immediately following the Acceptance Time or, if any Subsequent Offering Period is provided, during the twenty (20) Business Day period following the expiration date of such Subsequent Offering Period; provided , however , that in no event shall the Top-Up Option be exercisable (i) for a number of Shares in excess of the Company’s then authorized and unissued shares of common stock (giving effect to Shares reserved for issuance under the Company Equity Plans (as defined in Section 3.2(a) hereof) and pursuant to the exercise of any other securities convertible into or exchangeable into Shares, if any, as if such Shares were outstanding but not giving effect to Shares reserved for issuance

pursuant to the Rights, but including as authorized and unissued shares of common stock, for purposes of this Section 1.5 , any shares held in the treasury of the Company), (ii) if the issuance of Shares upon exercise of the Top-Up Option would require approval of the Company’s stockholders under the rules and regulations of the Nasdaq Stock Market or (iii) if, after the exercise of the Top-Up Option, Parent and Merger Sub would not hold a sufficient number of Shares to cause a short-form merger of the Company pursuant to Section 253 of the DGCL; provided , further , that the Top-Up Option shall automatically terminate upon the earlier to occur of (i) the Effective Time and (ii) the termination of this Agreement in accordance with its terms.

The Company shall, as soon as practicable following receipt of such notice, notify Parent and Merger Sub in writing of the number of Shares then outstanding and the number of Top-Up Shares. At the Top-Up Closing, Merger Sub shall pay to the Company in cash the aggregate purchase price required to be paid for the Top-Up Shares (calculated by multiplying the number of such Top-Up Shares by the Offer Price) and the Company shall cause to be issued to Merger Sub a certificate representing the Top-Up Shares, which certificate may include any legends required by applicable securities Laws; provided , however , at Parent’s election, instead of in cash the aggregate purchase price for the Top-Up Shares may be paid through the issuance of a full-recourse promissory note by Parent and Merger Sub, bearing simple interest at five percent (5%) per annum and due on the first anniversary of the Top-Up Closing, which promissory note may be prepaid, in whole or in part, without premium or penalty.

          (d) Merger Sub acknowledges that the Shares that Merger Sub 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. Merger Sub represents and warrants to the Company that Merger Sub is, and will be upon the purchase of the Top-Up Shares, an “accredited investor,” as defined in Rule 501 of Regulation D under the Securities Act of 1933, as amended (the “ Securities Act ”).

          (b) As soon as reasonably practicable after the Effective Time, the Surviving Corporation shall cause the Exchange Agent to mail to each holder of record of (i) a certificate or certificates (“ Certificates ”) that immediately prior to the Effective Time represented outstanding Shares or (ii) uncertificated Shares represented by book-entry (“ Book-Entry Shares ”) which, in each case, were converted into the right to receive the Merger Consideration with respect thereto pursuant to Section 3.1(a) , (A) a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates or Book-Entry Shares held by such Person (as defined in Section 9.3(f) hereof) shall pass, only upon proper delivery of the Certificates to the Exchange Agent or, in the case of Book-Entry Shares, upon adherence to the procedures set forth in the letter of transmittal, as applicable, and shall be in customary form and contain such other provisions as Parent or the Exchange Agent may reasonably specify) and (B) customary instructions for use in effecting the surrender of Certificates or Book-Entry Shares in exchange for the Merger Consideration payable with respect thereto pursuant to Section 3.1(a) and customary instructions consistent with Section 3.3(e) for use in effecting payment for lost, stolen or destroyed Certificates. Upon surrender of a Certificate or Book-Entry Share to the Exchange Agent, together with such letter of transmittal, properly completed and duly executed, and such other documents as the Exchange Agent may reasonably require, the holder of such Certificate or Book-Entry Share shall be entitled to receive in exchange therefor the Merger Consideration for each Share formerly represented by such Certificate or Book-Entry Share (in each case, subject to deduction for any required withholding Taxes), and such Certificate or Book-Entry Share shall forthwith be canceled. No interest shall be paid or shall accrue on any cash payable upon surrender of any Certificate or Book-Entry Share. In the event that the Merger Consideration is to be paid to a Person other than the Person in whose name any Certificate is registered, it shall be a condition of payment that the Certificate so surrendered shall be properly endorsed or otherwise in proper form for transfer, that the signatures on such Certificate or any related stock power shall be properly guaranteed and that the Person requesting such payment shall pay any transfer or other Taxes required by reason of such payment to a Person other than the registered holder of such Certificate or establish to the satisfaction of the Surviving Corporation that such Taxes have been paid or are not applicable. Until surrendered as contemplated by this Section 3.3 , each Certificate or Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender or transfer the Merger Consideration pursuant to Section 3.1(a) payable in respect of Shares theretofore represented by such Certificate or Book-Entry Shares, as applicable, without any interest thereon.

          (c) The payment of the applicable Merger Consideration upon the surrender for exchange of Certificates or Book-Entry Shares in accordance with the terms of this Article III

shall be deemed to have been delivered and paid in full satisfaction of all rights pertaining to the Shares (including the associated Rights) formerly represented by such Certificates or Book-Entry 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 that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Exchange Agent for transfer or transfer is sought for Book-Entry Shares, such Certificates or Book-Entry Shares shall be canceled and exchanged as provided in this Article III , subject to applicable Law in the case of Dissenting Shares (as defined in Section 3.5 hereof). The Exchange Agent shall invest the cash included in the Exchange Fund as directed by Parent; provided , however , that no such investment income or gain or loss thereon shall affect the amounts payable to holders of Shares. Any interest and other income resulting from such investments shall be the sole and exclusive property of Parent payable to Parent upon its request, and no part of such earnings shall accrue to the benefit of holders of Shares.

          (d) Any portion of the Exchange Fund (and any interest or other income earned thereon) that remains undistributed to the holders of Certificates or Book-Entry Shares nine (9) months after the Effective Time shall be delivered to the Surviving Corporation or one of its Affiliates upon demand, and any holders of Certificates or Book-Entry Shares who have not theretofore complied with this Article III shall thereafter look only to the Surviving Corporation, as general creditors thereof, for payment of the Merger Consideration with respect to Shares formerly represented by such Certificate or Book-Entry Share, without interest. Notwithstanding the foregoing, neither the Surviving Corporation nor any of its Affiliates shall be liable to any holder of Shares for any amount paid to a public official pursuant to applicable abandoned property, escheat or similar Laws. Any amounts remaining unclaimed by holders of Shares two (2) years after the Effective Time (or such earlier date immediately prior to such time when the amounts would otherwise escheat to or become property of any Governmental Entity (as defined in Section 4.4(b) hereof)) shall become, to the extent permitted by applicable Law, the property of the Surviving Corporation free and clear of any claims or interest of any Person previously entitled thereto.

          (e) If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit, in form and substance reasonably acceptable to Parent, of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent or the Exchange Agent, the posting by such Person of a bond in such amount as Parent or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Exchange Agent will deliver in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect thereof pursuant to this Agreement.

          (f) Any portion of the Merger Consideration made available to the Exchange Agent pursuant to Section 3.3(a) to pay for Dissenting Shares for which appraisal rights have been perfected shall be returned to the Surviving Corporation or one of its Affiliates, upon demand.

     Section 3.4 Withholding Rights . Parent, the Surviving Corporation or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable to any

holder of Shares, Company Stock Options, Company RSUs, or restricted stock or otherwise pursuant to this Agreement such amounts as Parent, 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 (the “ Code ”), or any provision of state, local or foreign tax Law. To the extent that amounts are so withheld and paid over to the appropriate taxing authority by Parent, 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 Person in respect of which such deduction and withholding was made.

     Section 3.5 Dissenting Shares . Notwithstanding anything in this Agreement to the contrary, Shares issued and outstanding immediately prior to the Effective Time that are held by any holder who has not voted in favor of the Merger and who is entitled to demand and properly demands appraisal of such Shares pursuant to, and who complies in all respects with, Section 262 of the DGCL (“ Dissenting Shares ”) shall not be converted into the right to receive the Merger Consideration, unless and until such holder shall have failed to perfect, or shall have effectively withdrawn or lost, such holder’s right to appraisal under the DGCL. Dissenting Shares shall be treated in accordance with Section 262 of the DGCL. If any such holder fails to perfect or withdraws or loses any such right to appraisal, then each such Share of such holder shall thereupon be converted into and become exchangeable only for the right to receive, as of the later of the Effective Time and the time that such right to appraisal has been irrevocably lost, withdrawn or expired, the Merger Consideration in accordance with Section 3.1(a) . Prior to the Effective Time, the Company shall promptly notify Parent of any demands for appraisal of any Shares, attempted withdrawals of such notices or demands and any other instruments received by the Company relating to rights to appraisal, and Parent shall have the right to participate in and direct all negotiations and proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Parent, make any payment with respect to, settle or offer to settle, or approve any withdrawal of any such demands.
