Pursuant to the terms of the Plan, the Compensation Committee of the Board (the “Committee”) has authorized this Agreement and approved the grant of restricted stock units (“RSUs”) evidenced hereby.

Unless otherwise indicated, any capitalized term used herein, but not defined herein, shall have the meaning ascribed to such term in the Plan.

(b)    Subject to Section 4 hereof, one-third (1/3) of the RSUs granted under this Agreement shall vest on each of the first, second, and third anniversaries of the Grant Date; provided that, on each vesting date, the Participant has been in Continuous Service through such date. For avoidance of doubt, subject to Section 4 hereof, the Participant shall not proportionately or partially vest in any RSUs during any period prior to each vesting date, and the Participant shall become vested in the RSUs only on the applicable vesting dates pursuant to this Section 1(b).

(c)    Upon satisfaction of the vesting requirements set forth in Section 1(b) and within ten (10) days following each vesting date, the Company shall issue the Participant one (1) share of Stock free and clear of any restrictions for each vested RSU.

(d)    For purposes of this Agreement, “Continuous Service” shall mean that the Participant’s service with the Company or any Subsidiary or Affiliate whether as an employee, director or consultant, is not interrupted or terminated.

The Participant shall not be entitled to receive any dividends or dividend equivalents in respect of any distributions paid with respect to any share of Stock underlying the RSUs granted under this Agreement that become declared or payable with respect to a record date prior to the dates on which shares of Stock are issued to the Participant pursuant to this Agreement.

3.    No Voting Rights

The Participant shall not be a stockholder of record and shall have no voting or other stockholder rights with respect to shares of Stock underlying the RSUs granted under this Agreement prior to the Company’s issuance of such shares following the applicable vesting date to the Participant.

(a)    Subject to Sections 4(b), (c) and (d), upon the Participant’s termination of Continuous Service for any reason, the unvested portion of the RSUs granted under this Agreement shall be immediately forfeited and cancelled.

(b)    Notwithstanding Section 1(b) or 4(a), upon the date of a termination of Continuous Service by the Participant on account of death, the Participant’s designated beneficiary shall be fully vested in any RSUs that remain unvested as of such date. The Company shall issue the Participant’s designated beneficiary one (1) share of Stock free and clear of any restrictions for each RSU that vests pursuant to this Section 4(b) within ten (10) days following the Participant’s death.

(c)    Notwithstanding Section 1(b) or 4(a), upon the date of a termination of Continuous Service by the Participant on account of Disability, the Participant shall be vested in a ProRata Number of RSUs (in addition to any RSUs that have vested as of such date pursuant to Section 1(b) hereof), and any unvested RSUs shall be immediately forfeited and canceled. The Company shall issue the Participant one (1) share of Stock free and clear of any restrictions for each RSU that vests pursuant to this Section 4(c) within ten (10) days following the date of termination of Continuous Service on account of Disability.

(d)    A “ProRata Number of RSUs” means a number of RSUs equal to one-third (1/3) of the RSUs granted under this Agreement, multiplied by a fraction, the numerator of which is the number of days that have elapsed during the period commencing on either (i) the Grant Date, if the date of termination of Continuous Service occurs prior to the first anniversary of the Grant Date or (ii) the anniversary of the Grant Date that immediately precedes the date of termination of Continuous Service, if the date of termination of Continuous Service occurs on or after the first anniversary of the Grant Date, and ending on the date of termination of Continuous Service, and the denominator of which is the number of days during the period commencing on either (A) the Grant Date, if the date of termination of Continuous Service occurs prior to the first anniversary of the Grant Date or (B) the anniversary of the Grant Date that immediately precedes the date of termination of Continuous Service, if the date of termination of Continuous Service occurs on or after the first anniversary of the Grant Date, and ending on the anniversary of the Grant Date that immediately follows the date of termination of Continuous Service.

(e)    For the purposes of Section 4, “Disability” shall mean (i) any physical or mental condition that would qualify the Participant for a disability benefit under any long-term disability plan maintained by the Company and applicable to him or her, (ii) if there is no such plan, such condition provided in any applicable governmental statute or regulation that constitutes a Disability,

or (iii) if there is no such applicable statute or regulation, such other condition as may be determined by the Committee in its sole discretion to constitute a Disability.

Except as otherwise provided herein or in the Plan, the RSUs shall not be assigned, negotiated, pledged, or hypothecated in any way or be subject to execution, attachment or similar process. No transfer of the Participant’s rights with respect to the RSUs, whether voluntary or involuntary, by operation of law or otherwise, shall be permitted. Immediately upon any attempt to transfer such rights, such RSUs, and all of the rights related thereto, shall be forfeited by the Participant.

(b)    The existence of this Agreement and the RSUs granted hereunder shall not affect in any way the right or power of the Board or the stockholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, any merger or consolidation of the Company or any affiliate, any issue of bonds, debentures, preferred or prior preference stocks ahead of or affecting the Stock, the authorization or issuance of additional shares of Stock, the dissolution or liquidation of the Company or any affiliate or sale or transfer of all or part of the assets or business of the Company or any affiliate, or any other corporate act or proceeding.

(c)    Upon a Change in Control, the purchaser(s) of the Company’s assets or stock or the surviving entity in a merger or consolidation may, in his, her or its discretion, deliver to the Participant the same kind of consideration that is delivered to the stockholders of the Company as a result of such Change in Control, or the Board may cancel all outstanding RSUs in exchange for consideration in cash or in kind, which consideration in both cases shall be determined by the Board.

Each determination, interpretation or other action made or taken pursuant to the provisions of this Agreement by the Committee or the Board in good faith shall be final, conclusive and binding for all purposes and upon all persons, including, without limitation, the Participant and the Company, and their respective heirs, executors, administrators, personal representatives and other successors in interest.

The transfer of any shares of Stock underlying the RSUs shall be effective only at such time as counsel to the Company shall have determined that the issuance and delivery of such shares are

in compliance with all applicable laws, regulations of governmental authority and the requirements of any securities exchange on which Stock is traded.

The Participant shall be liable for any and all taxes and contributions of any kind required by law to be withheld or made with respect to the vesting of the RSUs and delivery of any shares of Stock under this Agreement. The Participant authorizes the Participant’s employer (the “Employer”), in its discretion, to (a) require the Participant to remit to the Employer on the date on which the RSUs vest cash in an amount sufficient to satisfy all applicable required withholding taxes and social security or other contributions related to such vesting, (b) deduct from his or her regular salary payroll cash, on a payroll date following the date on which the RSUs vest, in an amount sufficient to satisfy such obligations, or (c) withhold from the total number of shares of Stock the Participant is to receive on a determination date a number of shares that has a total value equal to the amount necessary to satisfy any and all such obligations.
