Explanation of Responses:

1. Shares acquired pursuant to conversion of Restricted Stock Units (RSUs) 1 for 1. RSUs issued pursuant to issuer's Management Stock Purchase Plan under which executives may make advance elections to receive RSUs in lieu of a specified percentage or dollar amount of their annual incentive cash bonus under the bonus plan applicable to the executive. RSUs issued on the basis of a 33% discount to the fair market value of the issuer's Common Stock on the date the underlying bonus otherwise would be paid and generally vest 3 years after the date of grant, at which time they are converted into shares of issuer's Common Stock unless the executive has previously elected a longer deferral period. Transactions reported herein reflect conversion of RSUs into shares and withholding of sufficient shares to pay income taxes due. Price reflected above is based on 33% discount from fair market value of a share of issuer's Common Stock on 8/11/1998, the date of grant of the RSUs.

2. 500 of the total number of shares beneficially owned by the reporting person are held indirectly by the reporting person as they are held in his spouse's name.

3. Price reflects the fair market value of a share of the issuer's Common Stock on the date the shares are withheld by the issuer to pay taxes.

4. The date reported above is the date to which the reporting person previously had elected to defer conversion of the RSUs into shares of Common Stock.

5. The RSUs convert into shares of Common Stock on a 1 for 1 basis.
