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)	This transaction represents an allocation of shares held in trust by the Company's Employee Stock Ownership Plan on behalf of the reporting person. Shares held in trust by the plan are not distributed to the reporting person until retirement.
(2)	The price per share is the closing price of the Company's common stock on the date of the reported transaction.
(3)	The number of securities beneficially held following the reported transaction includes: 1,944 shares of restricted stock issued under Company's 2008 Stock Plan, which vest, subject to certain conditions, on 05/21/2013; 299 shares held in the Company's Employee Stock Ownership Plan for Mr. Ernst's benefit; 500 shares held in an individual retirement account for the benefit of Mr. Ernst's spouse; and approximately 4,372 shares held in a Company 401(k) account for Mr. Ernst's benefit based on a statement from the trustee.
(4)	The number of securities shown as being held in or acquired by the Company 401(k) account for Mr. Ernst's benefit are the approximate number of shares of common stock for which Mr. Ernst has the right to direct the vote under the 401(k) plan. Such shares are not directly allocated to plan participants, but are instead held in a unitized fund consisting primarily of common stock, together with a small percentage of short-term investments. Participants acquire units of this fund.
