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)	Sellers Capital Master Fund, Ltd. is a privately offered collective investment vehicle. Sellers Capital LLC is the investment adviser to and has investment discretion over securities of the issuer held by Sellers Capital Master Fund, Ltd. and therefore may be considered an indirect beneficial owner of those securities. Mr. Sellers is the Managing Member of Sellers Capital LLC and therefore also may be considered an indirect beneficial owner of those securities. Sellers Capital LLC and Mr. Sellers each disclaim beneficial ownership of the securities except to the extent of their pecuniary interest therein.
(2)	On March 6th, 2007, the number of shares beneficially owned, directly or indirectly, by the filing persons, pursuant to the definition of beneficial ownership set forth in Securities Exchange Act Rules 13d-3 and 16a-1(a)(1), exceeded 10 percent of the total shares outstanding of the class. However, due to an administrative oversight, Forms 4 were not filed with respect to the transactions set forth on this Form 4 filing.
(3)	As the number of transactions reportable on Table 1 exceeds the number of lines available on the form, this is the second of four Form 4s to be filed.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
