Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	The zeros in the table are placeholders only that are required by the EDGAR software and should be disregarded.
(2)	On June 9, 2003, Mittelstaedt Enterprises, L.P. ("Enterprises"), a partnership controlled by the reporting person, entered into a range forward purchase agreement (the "Agreement") with an unaffiliated third party (the "Buyer"), under which Enterprises agreed to deliver 135,000 shares of Common Stock to the Buyer on June 11, 2007 (the "Maturity Date"). Enterprises pledged 135,000 shares of Common Stock to the Buyer to secure its obligations under the Agreement.
(3)	The price per Share (the "Purchase Price") to be paid by the Buyer on the Maturity Date depended on the closing price of the Common Stock on that date (the "Maturity Price"). If the Maturity Price were less than or equal to $11.92, the Purchase Price would be $11.92. If the Maturity Price were greater than or equal to $19.39, the Purchase Price would be $19.39. If the Maturity Price were greater than $11.92 but less than $19.39, the Purchase Price would be the Maturity Price. (These share numbers and dollar amounts have been adjusted pursuant to the Agreement to reflect the two 3-for-2 stock splits of the Common Stock that occurred on June 25, 2004 and March 13, 2007.)
(4)	The Maturity Price was $30.00. Accordingly, the Purchase Price was $19.39. On June 11, 2007, Enterprises settled its obligation under the Agreement to deliver 135,000 shares to the Buyer, and was paid the Purchase Price in cash.
