Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Committee shall notify each Optionee and Participant as soon as practicable prior to the effective date of such proposed transaction. The Committee in its sole discretion may permit an Optionee to exercise an Option until ten days prior to such transaction with respect to all vested and exercisable Shares covered thereby and with respect to such number of unvested Shares as the Committee shall determine. In addition, the Committee may provide that any forfeiture provision or Company repurchase option applicable to any Restricted Share Award shall lapse as to such number of Shares as the Committee shall determine, contingent upon the occurrence of the proposed dissolution or liquidation at the time and in the manner contemplated. To the extent an Option has not been previously exercised, the Option shall terminate automatically immediately prior to the consummation of the proposed action. To the extent a forfeiture provision applicable to a Restricted Share Award has not been waived by the Committee, the related Restricted Share Award shall be forfeited automatically immediately prior to the consummation of the proposed action.
