        <footnote id="F1">Restricted Stock Units (RSUs) convert into Common Stock on a one-for-one basis.  These RSUs issued under the issuer's Management Stock Purchase Plan (MSPP) pursuant to which certain executives may make an advance election to receive RSUs in lieu of a specified percentage or dollar amount of such executive's annual incentive cash bonus under the bonus plan applicable to the executive.  The RSUs are issued in whole units on the basis of a 33% discount from the fair market value of the issuer's common stock on the date that the underlying bonus is determined and generally vest 3 years from the date of grant at which time they convert into shares of common stock unless the executive previously has selected a longer deferral period.</footnote>
        <footnote id="F2">The Restricted Stock Units (RSUs) granted herein are in connection with the Company's grant of long-term incentive awards for the 2010 Fiscal Year.  These RSUs, which represent 75% of the long-term incentive awarded to the executive, vest in three equal installments on April 1, 2011, March 1, 2012 and March 1, 2013 and convert into shares of common stock on a one-for-one basis unless the executive previously has selected a longer deferral period.</footnote>
        <footnote id="F3">The options vest 100% on 3/1/2013.  The options convert into shares of common stock on a one-for-one basis.</footnote>
