4. No Rights in Shares Until Issued. Neither the Grantee nor Grantee’s heirs, executor or administrator shall be, or have any of the rights or privileges of, a stockholder of the Corporation in respect of any of the shares issuable upon the exercise of the option herein granted, unless and until such shares are fully paid and issued to him/her upon exercise of this Option.

5. Option Not Transferable During Grantee’s Lifetime. This option shall not be transferable by Grantee other than by last will and testament or by the laws of descent and distribution. During Grantee’s lifetime, this option shall be exercisable only by Grantee or Grantee’s guardian or legal representative. In the event of the Grantee’s death, the personal representative of the Grantee’s estate or the person or persons to whom the Option is transferred by will or the laws of descent and distribution may exercise the Option in accordance with its terms.

6. Effect of Change in Stock. In the event of a reorganization, recapitalization, stock split, stock dividend, merger, consolidation, rights offering or like transaction, the Committee shall make or provide for such adjustment in the exercise price of the option or in the number of kinds of stock covered by the option as it may, in its discretion, deem to be equitable provided, however, in the event of (a) the merger or consolidation of the Corporation with or into another corporation or corporations in which the Corporation is not the surviving corporation, (b) the adoption of any plan for the dissolution of the Corporation, or (c) the sale or exchange of all or substantially all the assets of the Corporation for cash or for shares of stock or other securities of another corporation, the Committee may elect to cancel this option. In the event the option is canceled, the Corporation, or the corporation assuming the obligations of the Corporation hereunder, shall pay Grantee an amount of cash or stock, as determined by the Committee, equal to the Fair Market Value per share of the Stock immediately preceding such cancellation over the option exercise price, multiplied by the number of shares subject to the option.
