11. Withholding. The Company shall have the right to require the grantee to remit to the Company an amount sufficient to satisfy any federal, state or local withholding tax requirements prior to the delivery of any certificate for shares of Class A common stock. If and to the extent the Board authorizes, in its sole discretion, a grantee may make an election, by means of a form of election the Board prescribes, to have shares of Class A common stock that are acquired upon exercise of a stock option withheld by the Company or to tender other shares of Class A common stock or other securities of the Company owned by the grantee to the Company at the time of exercise of a stock option to pay the amount of tax that would otherwise be required by law to be withheld by the Company. Any such election shall be irrevocable and shall be subject to termination by the Board, in its sole discretion, at any time. Any securities so withheld or tendered shall be valued by the Board as of the date of exercise.
12. Transferability of Awards. Only the grantee of an award may exercise rights under the award during the grantees lifetime, and a grantee may not transfer those rights except by will or by the laws of descent and distribution. When a grantee dies, the personal representative or other person entitled to succeed to the rights of the grantee may exercise those rights. Any successor to a grantee must furnish proof satisfactory to the Company of the successors right to receive the award under the grantees will or under the applicable laws of descent and distribution. Except as stated in this Section 12, no stock option or interest therein and, for a period of one year after the date of grant, no restricted stock award or any interest therein, shall be subject to the debts, contracts or engagements of the grantee or the grantees successors in interest, nor shall they be subject to disposition by transfer, alienation, anticipation, pledge, encumbrance, assignment or any other means, whether such disposition is voluntary or involuntary or by operation of law by judgment, levy, attachment, garnishment or any other legal or equitable proceedings, including bankruptcy, and any attempted disposition thereof shall be null and void and of no effect.
