The Blue Harbour Reporting Persons and Mr. Cooperman do not have any agreements or understandings between them relating to the acquisition, disposition, holding or voting of the Common Stock held by them and each expressly disclaims beneficial ownership for all purposes of the Common Stock held by the others. The Blue Harbour Reporting Persons and Mr. Cooperman have, on occasion, coordinated their market purchases of the Common Stock and call options to purchase Common Stock in the past, and may decide to coordinate purchases and sales in the future. The Reporting Persons have filed this statement solely because they may be deemed to be a "group" for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the "Act"), as a result of their agreement to submit the May 1 Letter to the Company's Chief Executive Officer. However, the Blue Harbour Reporting Persons and Mr. Cooperman each disclaim membership in a "group" with the other Reporting Person. (1) The Blue Harbour Reporting Persons. (a) - (c) and (f) The Blue Harbour Reporting Persons are Blue Harbour Strategic Value Partners Master Fund, LP, a Cayman Islands exempted limited partnership (the "Fund"), Blue Harbour GP, LLC, a Delaware limited liability company ("Fund GP"), Blue Harbour Group, LP, a Delaware limited partnership ("Manager"), Blue Harbour Holdings, LLC, a Delaware limited liability company ("Manager GP"), and Clifton S. Robbins ("Mr. Robbins"), a citizen of the United States of America. The address of the principal office of each of the Fund, Manager, Manager GP and Fund GP is 240 Greenwich Avenue, 3rd Floor, Greenwich, Connecticut 06830, and Mr. Robbins' business address is c/o Manager at the foregoing address.

Manager GP is principally involved in the business of serving as the general partner of Manager. (d) - (e) During the last five years, none of the Blue Harbour Reporting Persons nor, to the best of their knowledge, any of their officers and directors, has (i) been convicted in a criminal proceeding (excluding traffic 8 violations or similar misdemeanors) or (ii) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws (2) Leon G.

Mr. Cooperman is the ultimate controlling person of Associates, Capital LP, Investors LP, Equity LP, and Advisors.
