No Key Employee shall have any rights as a shareholder with respect to any share of Common Stock covered by an Option unless and until such Key Employee shall have become the holder of record of such share, and, other than pursuant to an adjustment made in accordance with Section 13.3 hereof, no adjustment shall be made for dividends (ordinary or extraordinary, whether in cash, securities or other property or distributions or other rights) in respect of such share for which the record date is prior to the date on which such Key Employee shall have become the holder of record thereof." 7.

Section 10.1 of the Plan is hereby amended by adding the following sentence to the end thereof to read as follows: "Following the Distribution (as defined below), a termination of employment with an Employer includes a transfer of employment from the Company (or a Subsidiary) to Resources (or a Resources Subsidiary) and vice versa.

The Committee may also permit withholding to be satisfied by the transfer to the Company of shares of Common Stock theretofore owned by the holder of the award with respect to which withholding is required, except with respect to Options. If shares of Common Stock are used to satisfy tax withholding, such shares shall be valued based on the fair market value when the tax withholding is required to be made."
