3. EFFECT OF REVERSION; RETURN OF STOCK CERTIFICATE(S).

If Stockholder holds physical stock certificates, Stockholder agrees in the event of reversion to promptly return the stock certificates(s) representing the reverted shares to the Company. Upon return of such stock certificate(s), the Company will issue the vested shares, if any, to Stockholder in electronic form to the extent that they are not repurchased by the Company pursuant to its right to repurchase as set forth in this Agreement or in Article Fourth. Notwithstanding the foregoing, if Stockholder has not returned such stock certificate(s) within sixty (60) days following the date the Bonus Stock reverted to the Company, in whole or in part, Stockholder hereby appoints the Company or its agents to take all such action needed to effect the cancellation of such stock certificate(s).

5. CONTINUATION OF VESTING UPON SPECIAL RETIREMENT. If Stockholder is a director of the Company or an Executive Officer and Stockholder’s affiliation with the Company or any Affiliate terminates as a result of Stockholder’s Special Retirement, any unvested shares of Bonus Stock shall continue to vest in accordance with the vesting schedule set forth in Section 2 above. If Stockholder is not a director of the Company or an Executive Officer and Stockholder’s affiliation with the Company or an Affiliate terminates as a result of Stockholder’s Special Retirement, unvested shares of Bonus Stock that Stockholder has held at least twelve (12) months prior to the date of Special Retirement shall continue to vest in accordance with the vesting schedule set forth in Section 2 above, and any unvested shares of Bonus Stock that Stockholder did not hold at least twelve (12) months prior to the date of Special Retirement shall revert to the Company, as described in Section 3 above. Notwithstanding anything to the contrary above, all unvested shares of Bonus Stock shall revert to the Company in the event that Stockholder violates the terms of his or her inventions, copyright and confidentiality agreement with the Company or breaches his or her other contractual or legal obligations to the Company.

6. TAX WITHHOLDING. If the Company is required to withhold any federal, state, local or other taxes upon the vesting or any acceleration of vesting of the Bonus Stock, Stockholder agrees that the Company has the right to repurchase a sufficient number of shares of Bonus Stock at the then current Formula Price (as defined in the Plan) to meet the withholding obligation based on the minimum rates required by law. However, the Committee, in its sole and absolute discretion, may permit the Stockholder to satisfy the withholding obligations by cash payment or through payroll deductions in an amount sufficient to meet this obligation at the time of vesting or acceleration of vesting.

7. RIGHTS, RESTRICTIONS AND LIMITATIONS.

(a) Article Fourth. All shares of Bonus Stock issued to Stockholder pursuant to this Agreement are subject to the rights, restrictions and limitations set forth in Article Fourth.

(b) Additional Right of Repurchase. In addition to any other rights the Company may have pursuant to Article Fourth or any Company repurchase deferral program, the Company shall have the right to repurchase all or any portion of the Bonus Stock that vests: (i) after the date that is one hundred eighty (180) days prior to the date of termination of Stockholder’s affiliation with the Company or an Affiliate as an employee, director or consultant; and (ii) during a Special Retirement. The Company’s right to repurchase such Bonus Stock shall begin on the one hundred eightieth (180^th) day after the first, second, third and fourth anniversaries of the Commencement Date. The Company shall exercise its right to repurchase within two hundred forty (240) days after a Commencement Date anniversary, by mailing written notice of the number of shares of Bonus Stock that the Company desires to repurchase to Stockholder’s address of record with the Company’s transfer agent. The purchase price for the Bonus Stock shall be the Formula Price (as defined in the Plan) in effect on the Commencement Date anniversary immediately preceding the date on which the Company exercises its right of repurchase. The Company shall pay for such shares in cash, by Company check or via electronic transfer within two hundred seventy (270) days of such Commencement Date anniversary. The Company may exercise its repurchase right on one or multiple Commencement Date anniversary periods with respect to all or any portion of the Bonus Stock.

10. EMPLOYMENT AT WILL.

(a) If Stockholder is an employee or consultant of the Company or an Affiliate, such employment or affiliation is not for any specified term and may be terminated by employee or by the Company or an Affiliate at any time, for any reason, with or without cause and with or without notice. Nothing in this Agreement (including, but not limited to, the vesting of the Bonus Stock pursuant to the schedule set forth in Section 2 herein), the Plan or any covenant of good faith and fair dealing that may be found implicit in this Agreement or the Plan shall: (i) confer upon Stockholder any right to continue in the employ of, or affiliation with, the Company or an Affiliate; (ii) constitute any promise or commitment by the Company or an Affiliate regarding the fact or nature of future positions, future work assignments, future compensation or any other term or condition of employment or affiliation; (iii) confer any right or benefit under this Agreement or the Plan unless such right or benefit has specifically accrued under the terms of this Agreement or Plan; or (iv) deprive the Company of the right to terminate Stockholder at will and without regard to any future vesting opportunity that Stockholder may have.

(b) Stockholder acknowledges and agrees that the right to continue vesting in the Bonus Stock pursuant to the schedule set forth in Section 2 is earned only by continuing as an employee or consultant at the will of the Company or as a director (not through the act of being hired, being granted this Bonus Stock or any other award or benefit) and that the Company has the right to reorganize, sell, spin-out or otherwise restructure one or more of its businesses or Affiliates at any time or from time to time, as it deems appropriate (a “reorganization”). Stockholder acknowledges and agrees that such a reorganization could result in the termination of Stockholder’s relationship as an employee or consultant to the Company or an Affiliate, or the termination of Affiliate status of Stockholder’s employer and the loss of benefits available to Stockholder under this Agreement, including but not limited to, the termination of the right to continue vesting the Bonus Stock under this Agreement. Stockholder further acknowledges and agrees that this Agreement, the Plan, the transactions contemplated hereunder and the vesting schedule set forth herein or any covenant of good faith and fair dealing that may be found implicit in any of them do not constitute an express or implied promise of continued engagement as an employee or consultant for the term of this Agreement, for any period, or at all, and shall not interfere in any way with Stockholder’s right or the Company’s right to terminate Stockholder’s relationship as an employee or consultant at any time, with or without cause and with or without notice.

11. CAPITAL ADJUSTMENTS. The Formula Price and number of shares of Bonus Stock shall be appropriately adjusted for any increase or decrease in the number of shares of stock which the Company has issued and outstanding resulting from any stock split, stock dividend, combination of shares or any other change, or any exchange for other securities or any reclassification, reorganization, redesignation, recapitalization or otherwise.
