Effect of Change in Control on Options and SARs.
(a) Accelerated Vesting. Notwithstanding any other provision of the Plan to the contrary except as provided in this Section 14.1(a), the Committee, in its sole discretion, may provide in any Award Agreement or, in the event of a Change in Control, may take such actions as it deems appropriate to provide for the acceleration of the exercisability and vesting in connection with such Change in Control of any or all outstanding Options and SARs and shares acquired upon the exercise of such Options and SARs upon such conditions and to such extent as the Committee shall determine. Any unexercisable or unvested portion of each outstanding Nonemployee Director Option and any shares acquired upon the exercise thereof shall be immediately exercisable and vested in full as of the date ten (10) days prior to the date of the Change in Control but conditioned upon the consummation of the Change in Control.
(b) Assumption or Substitution. In the event of a Change in Control, the surviving, continuing, successor, or purchasing entity or parent thereof, as the case may be (the Acquiror), may, without the consent of any Participant, either assume the Companys rights and obligations under outstanding Options and SARs or substitute for outstanding Options and SARs substantially equivalent options and SARs (as the case may be) for the Acquirors stock. Any Options or SARs which are not assumed by the Acquiror in connection with the Change in Control nor exercised as of the time of consummation of the Change in Control shall terminate and cease to be outstanding effective as of the time of consummation of the Change in Control.
(c) Cash-Out of Options. The Committee may, in its sole discretion and without the consent of any Participant, determine that, upon the occurrence of a Change in Control, each or any Option or SAR outstanding immediately prior to the Change in Control shall be canceled in exchange for a payment with respect to each vested share of Stock subject to such canceled Option or SAR in (i) cash, (ii) stock of the Company or of a corporation or other business entity a party to the Change in Control, or (iii) other property which, in any such case, shall be in an amount having a Fair Market Value equal to the excess of the Fair Market Value of the consideration to be paid per share of Stock in the Change in Control over the exercise price per share under such Option or SAR (the Spread). In the event such determination is made by the Committee, the Spread (reduced by applicable withholding taxes, if any) shall be paid to Participants in respect of their canceled Options and SARs as soon as practicable following the date of the Change in Control.
