Explanation of Responses:

1. Accrual of Deferred Stock Units pursuant to the Elective Deferral Plan for Non-Employee Directors. Deferred Stock Units under the Plan accrue on the first day of each calendar year (at the closing price of a share of the Company's common stock on the last day of the preceding month) and on each dividend record date (at the closing price of a share of the Company's common stock on such dividend record dates).

2. Converts on a 1 for 1 basis.

3. Deferred Stock Units are settled in cash upon the reporting person's retirment as provided in the Company's Elective Deferral Plan. Once each plan year, deferred compensation under the Elective Deferral Plan may be reallocated by the reporting person, effective as of the following plan year, to an interest-bearing cash account or as Deferred Stock Units under the plan.

4. Includes Deferred Stock Units accrued pursuant to a dividend reinvestment feature of the Elective Deferral Plan.
