ARTICLE II.

EFFECT OF THE MERGER ON CAPITAL STOCK

          Section 2.1 Effect of the Merger on Capital Stock . At the Effective Time, as a result of the Merger and without any action on the part of MergerCo or the Company or the holder of any capital stock of MergerCo or the Company:

          (a) Cancellation of Certain Common Stock . Each share of Common Stock that is owned by the Company (as treasury stock or otherwise), Parent or MergerCo or any of their direct or indirect wholly owned Subsidiaries (other than Shares held on behalf of third parties) will be cancelled automatically and will cease to exist, and no consideration will be delivered in exchange therefor (each such Share, an “ Excluded Share ” and such Shares collectively, the “ Excluded Shares ”).

          (b) Conversion of Common Stock . Each share of Common Stock (each, a “ Share ” and collectively, the “ Shares ”) issued and outstanding immediately prior to the Effective Time (other than Excluded Shares) will be converted into the right to receive $31.55 in cash, without interest (the “ Merger Consideration ”).

          (c) Cancellation of Shares . At the Effective Time, all Shares will no longer be outstanding and all Shares will be cancelled and will cease to exist, and each

holder of a certificate formerly representing any such Shares (each, a “ Certificate ”) will cease to have any rights with respect thereto, except (in the case of Shares other than Excluded Shares) the right to receive the Merger Consideration, without interest, in accordance with Section 2.2.

          (d) Conversion of MergerCo Capital Stock . Each share of common stock, par value $0.001 per share, of MergerCo issued and outstanding immediately prior to the Effective Time will be converted into one (1) share of common stock, par value $0.001 per share, of the Surviving Corporation.

          (e) No Dissenters’ Rights . Pursuant to Section 92A.390 of the NRS, no dissenters’ rights or rights of appraisal will apply in connection with the Merger.

          Section 2.2 Surrender of Certificates . (a) Paying Agent . Prior to the Effective Time, for the benefit of the holders of Shares (other than Excluded Shares), Parent will (i) designate, or cause to be designated, a bank or trust company that is reasonably acceptable to the Company (the “ Paying Agent ”) and (ii) enter into a paying agent agreement, in form and substance reasonably acceptable to the Company, with such Paying Agent to act as agent for the payment of the Merger Consideration in respect of Certificates upon surrender of such Certificates (or effective affidavits of loss in lieu thereof) in accordance with this Article II from time to time after the Effective Time. Promptly after the Effective Time, Parent will deposit, or cause to be deposited, with the Paying Agent cash in the amount necessary for the payment of the Merger Consideration pursuant to Section 2.1(b) upon surrender of such Certificates (such cash being herein referred to as the “ Payment Fund ”). The Payment Fund shall not be used for any other purpose. The Payment Fund shall be invested by the Paying Agent as directed by the Parent; provided , however , that such investments shall be in obligations of or guaranteed by the United States of America or any agency or instrumentality thereof and backed by the full faith and credit of the United States of America, in commercial paper obligations rated A-1 or P-1 or better by Moody’s Investors Service, 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 (based on the most recent financial statements of such bank which are then publicly available). Any net profit resulting from, or interest or income produced by, such investments shall be payable to the Parent.

          (b) Payment Procedures . As promptly as practicable after the Effective Time, the Surviving Corporation will instruct the Paying Agent to mail to each holder of record of Shares (other than Excluded Shares) a letter of transmittal in customary form as reasonably agreed by the parties specifying that delivery will be effected, and risk of loss and title to Certificates will pass, only upon proper delivery of Certificates (or effective affidavits of loss in lieu thereof) to the Paying Agent and instructions for use in effecting the surrender of the Certificates (or effective affidavits of loss in lieu thereof) in exchange for the Merger Consideration. Upon the proper surrender of a Certificate (or effective affidavit of loss in lieu thereof) to the Paying Agent, together with a properly completed letter of transmittal, duly executed, and such other documents as may reasonably be requested by the Paying Agent, the holder of such

Certificate will be entitled to receive in exchange therefor cash in the amount (after giving effect to any required tax withholdings) that such holder has the right to receive pursuant to this Article II, and the Certificate so surrendered forthwith will be cancelled. No interest will be paid or accrued on any amount payable upon due surrender of the Certificates. In the event of a transfer of ownership of Shares that is not registered in the transfer records of the Company, cash to be paid upon due surrender of the Certificate may be paid to such a transferee if the Certificate formerly representing such Shares is presented to the Paying Agent accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer Taxes have been paid or are not applicable.

          (c) Withholding Taxes . The Surviving Corporation and the Paying Agent will be entitled to deduct and withhold from amounts otherwise payable pursuant to this Agreement to any holder of Shares or holder of Stock Options or Company RSUs any amounts required to be deducted and withheld with respect to such payments under the Code and the rules and Treasury Regulations promulgated thereunder, or any provision of state, local or foreign Tax law. With respect to any such payment to be made to any Person, to the extent required by Law, the Parent may withhold from such payment an amount equal to 10% thereof and pay over such amount to the Internal Revenue Service if such Person (i) has, at any time during the shorter of the periods described in section 897(c)(1)(A)(ii) of the Code and the Treasury Regulations thereunder, beneficially owned more than 5%, taking into account the constructive ownership rules described in section 897(c)(6)(C) of the Code and the Treasury Regulations thereunder, of the fair market value of any class of stock of the Company, and (ii) has not, prior to the time for making such payment, delivered to the Acquisition Sub a certificate, as contemplated under and meeting the requirements of section 1.1445-2(b)(2)(i) of the Treasury Regulations, to the effect that such Person is not a foreign Person within the meaning of the Code and applicable Treasury Regulations; provided, however , that Parent shall not make any withholding pursuant to the foregoing sentence if the Company has delivered to Parent prior to Closing a statement described in Treasury Regulations section 1445-2(c)(3) reasonably acceptable to Parent. With respect to the foregoing sentence, the Parent shall not be deemed to be in default of any of its obligations under this Agreement by virtue of having withheld such amount and the amount so withheld shall be deemed to have been paid to such Person for all purposes under this Agreement. Any amounts so deducted and withheld will be timely paid to the applicable Tax authority and will be treated for all purposes of this Agreement as having been paid to the holder of the Shares or holders of Stock Options or Company RSUs, as the case may be, in respect of which such deduction and withholding was made.

          (d) No Further Transfers . After the Effective Time, there will be no transfers on the stock transfer books of the Company of Shares that were outstanding immediately prior to the Effective Time other than to settle transfers of Shares that occurred prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Paying Agent, they will be cancelled and exchanged for the Merger Consideration as provided in this Article II.

          (e) Termination of Payment Fund . Any portion of the Payment Fund that remains undistributed to the holders of the Certificates one year after the Effective Time will be delivered to the Surviving Corporation, on demand, and any holder of a Certificate who has not theretofore complied with this Article II will thereafter look only to the Surviving Corporation for payment of his or her claims for Merger Consideration. Notwithstanding the foregoing, none of Parent, the Company, the Surviving Corporation, the Paying Agent or any other Person will be liable to any former holder of Shares for any amount delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws.

          (f) Lost, Stolen or Destroyed Certificates . In the event any Certificate has 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 customary amount and upon such terms as the Surviving Corporation may determine are necessary as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration pursuant to this Agreement.

          Section 2.3 Adjustments to Prevent Dilution . In the event that the Company changes the number of Shares, or securities convertible or exchangeable into or exercisable for Shares, issued and outstanding prior to the Effective Time as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, subdivision, issuer tender or exchange offer, or other similar transaction, the Merger Consideration will be equitably adjusted to reflect such change; provided that nothing herein shall be construed to permit the Company to take any action with respect to its securities that is prohibited by the terms of this Agreement.

          Section 2.4 Treatment of Stock Options and Other Equity Based Awards . (a) Each option to purchase Shares, whether or not vested (collectively, the “ Stock Options ”), outstanding immediately prior to the Effective Time pursuant to the Company Benefit Plans will at the Effective Time be cancelled and the holder of such Stock Option, in full settlement of such Stock Option, will be entitled to receive from the Surviving Corporation an amount (subject to any applicable withholding tax) in cash equal to the product of (x) the excess, if any, of the Merger Consideration over the exercise price per Share of such Stock Option multiplied by (y) the number of Shares subject to such Stock Option (with the aggregate amount of such payment rounded up to the nearest whole cent). The holders of Stock Options will have no further rights in respect of any Stock Options from and after the Effective Time.

          (b) As of the Effective Time, each Company RSU, whether or not vested, that is outstanding immediately prior to the Effective Time will be cancelled and extinguished, and the holder thereof will be entitled to receive from the Surviving Corporation in respect of each such RSU an amount (subject to any applicable withholding tax) in cash equal to the Merger Consideration, without interest.

          (c) The Company shall take all actions with respect to the Company Employee Stock Purchase Plan (the “ Company ESPP ”), including, if appropriate, amending the terms of the Company ESPP, that are necessary to (i) cause the ending date of the Offering Period (as such term is defined in the Company ESPP) under the Company ESPP that is in effect as of the date of this Agreement to occur on or before the last trading day prior to the Effective Time, if the Effective Time is prior to the end of such Offering Period, (ii) cause all then-existing offerings under the Company ESPP to terminate immediately following the purchase on the earlier of the last trading day prior to the Effective Time or the ending date of the Offering Period that is in effect as of the date of this Agreement (such earlier date, the “ Final Purchase Date ”), (iii) suspend all future offerings that would otherwise commence under the Company ESPP following the Final Purchase Date and (iv) cease all further payroll deductions under the Company ESPP effective as of the Final Purchase Date. On the Final Purchase Date, the Company shall apply the funds credited as of such date under the Company ESPP within each participant’s payroll withholding account to the purchase of whole shares of Company Common Stock in accordance with the terms of the Company ESPP, which shares shall be treated in the manner described in Section 2.1.

          (d) Prior to the Effective Time, the Company will adopt such resolutions and will take such other actions including, without limitation, adopting any plan amendments and obtaining any required consents, as shall be required to effectuate the actions contemplated by this Section 2.4, without paying any consideration or incurring any debts or obligations on behalf of the Company or the Surviving Corporation.

          Section 2.5 Timing of Equity Rollover . For the avoidance of doubt, the parties acknowledge and agree that the contribution of Shares and certain other assets to Parent pursuant to the Equity Rollover Commitments shall be deemed to occur immediately prior to the Effective Time and prior to any other event described above.
