Options to purchase common stock of the Company were granted pursuant to the Company's Amended 2000 Long-Term Incentive Plan (the "Plan") at a purchase price of $37.70, the closing selling price per share of the Company's common stock on the New York Stock Exchange on the date of grant.  In accordance with the Plan, each option has a maximum term of ten years and will become exercisable for the option shares in four equal and successive annual installments over the optionee's period of service with the Company, beginning one year after the grant date.

With respect to the aforementioned grants, the Company's form option agreement under the Plan was amended such that accelerated vesting of options would not automatically occur upon a Change of Control (as such term is defined in the Plan), but only upon and in the event of a second triggering event: termination of the employee by the Company or resignation by the employee for good reason within 12 months following any such Change of Control. 

Revised Executive Employment Agreements:  The following description sets forth the material revisions to the standard executive employment agreements ("Agreements") approved by the Committee:

• With respect to the provisions related to termination without cause or resignation for good reason, the approved modifications to the Agreements will provide for:
• payment of full COBRA premiums for twenty-four (24) months following a termination;
• severance compensation to be calculated as a flat 36 months' severance, determined at the executive officer's then current rate of base pay; and
• a pro-rated amount, based on timing of the executive officer's termination or resignation relative to the end of the then current fiscal year, of the target bonus percentage applicable to such executive officer.

• With respect to the provisions related to termination due to Change of Control, the approved modifications to the Agreements will provide for:
• payment of full COBRA premiums for twenty-four (24) months following a termination;
• severance compensation to be calculated as a flat 36 months' severance, determined at the executive officer's then current rate of base pay; and
• one hundred percent (100%) of the target bonus percentage applicable to the executive officer.
