    <remarks>On April 20, 2006, Mr. Ward entered into a forward sale agreement (the &quot;Agreement&quot;) relating to up to 2,813,854 shares (the &quot;Base Amount&quot;) of common stock.  The Agreement provides that Mr. Ward will deliver on April 20, 2007 a number of shares of common stock or the cash equivalent of the shares of common stock equal to the product of (i) the Base Amount and (ii) the Settlement Ratio, which will be determined as follows:

(a)  If the closing price of the common stock on April 20, 2007 (the  &quot;Settlement Price&quot;) is less than or equal to $27.9683 (the &quot;Hedged Value&quot;), the Settlement Ratio will be one;

(b)  If the Settlement Price is greater than the Hedged Value but less than $42.3309 (the &quot;Upside Limit&quot;), the Settlement Ratio will be equal to the Hedged Value divided by the Settlement Price; and

(c)  If the Settlement Price is equal to or greater than the Upside Limit, the Settlement Ratio will be equal to the sum of the Hedged Value divided by the Settlment Price and a fraction the numerator of which is equal to the difference between the Settlement and the Upside Limit and the denominator of which is equal to the Settlement Price.

In consideration therefore, the Agreement provides that Mr. Ward will receive a purchase price of $74,669,378.78.</remarks>
