The Plan sets forth certain earlier expiration dates upon the option holder's termination of employment or cessation of Board service, as the case may be.  In addition, the exercisability of outstanding options may be accelerated as approved by the committee administering the Plan, and will be accelerated upon the occurrence of certain specified &quot;change in control&quot; events, in which case the options will be automatically purchased by the Company at a defined acceleration price.</footnote>
        <footnote id="F3">These phantom stock units were allocated under the Company's Compensatory Benefit Plan (the &quot;Plan&quot;) and will be settled (on a 1-for-1 basis) upon the reporting person's retirement, death, disability, or other termination of employment.  Units included in column 9 that represent an increase from the last report filed by the reporting person and are not otherwise accounted for by a transaction on this form were allocated under the Plan as of January 2,  2004.
