Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 5(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)	In addition to Pershing Square Capital Management, L.P., a Delaware limited partnership ("Pershing Square"), this Form 3 is being filed jointly by PS Management GP, LLC, a Delaware limited liability company ("PS Management"), and William A. Ackman, a citizen of the United States of America (collectively, the "Reporting Persons"), each of whom has the same business address as Pershing Square and may be deemed to have a pecuniary interest in securities reported on this Form 3 (the "Subject Securities").
(2)	Pershing Square advises the accounts of Pershing Square, L.P., a Delaware limited partnership ("PS"), Pershing Square II, L.P., a Delaware limited partnership ("PS II"), Pershing Square International, Ltd., a Cayman Islands exempted company ("PS International"), and Pershing Square Holdings, Ltd., a limited liability company incorporated in Guernsey ("PSH" and together with PS, PS II and PS International, the "Pershing Square Funds").
(3)	Pershing Square, as the investment adviser to the Pershing Square Funds, may be deemed to be the beneficial owner of the Subject Securities for purposes of Rule 16a-1(a) under the Securities Exchange Act of 1934. As the general partner of Pershing Square, PS Management may be deemed to be the beneficial owner of the Subject Securities for purposes of Rule 16a-1(a). By virtue of William A. Ackman's position as Chief Executive Officer of Pershing Square and managing member of PS Management, William A. Ackman may be deemed to be the beneficial owner of the Subject Securities for purposes of Rule 16a-1(a). Each of the Reporting Persons disclaims any beneficial ownership of any of the Subject Securities, except to the extent of any pecuniary interest therein.
(4)	William Doyle, a member of the board of directors of the Issuer, was elected to that board as a representative of the Reporting Persons, the Pershing Square Funds and Pershing Square GP, LLC. As a result, each of those persons are directors by deputization for purposes of Section 16 of the Securities Exchange Act of 1934.
(5)	The total return swaps referred to in Table II provide for cash settlement at their expiration date. They do not give the Reporting Persons or the Pershing Square Funds direct or indirect voting, investment or dispositive control over any securities of the Issuer and do not require the counterparty thereto to acquire, hold, vote or dispose of any securities of the Issuer. Accordingly, the Reporting Persons disclaim any beneficial ownership of any shares of Common Stock that may be referenced in the swap contracts or shares of Common Stock or other securities or financial instruments that may be held from time to time by the counterparty thereto.
