Way, Edward P. Garden, Jerry W. Levin and Triarc Companies, Inc. (collectively, the "Trian Entities") regarding their respective interests in the Common Stock because they might have been deemed to constitute a "group" with respect to such Common Stock for purposes of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). On September 16, 2008, Trian Fund Management, L.P. and Sandell Asset Management Corp. entered into a Termination Agreement ("Termination Agreement") pursuant to which the Agreement between Trian Fund Management, L.P. and Sandell Asset Management Corp., dated November 4, 2005, as amended (the "Agreement") was terminated, effective immediately, with certain provisions relating to expenses, indemnification, contribution and regulatory reporting surviving the termination, but each disclaim membership in any "group" for the foregoing purposes by reason of any continuing rights or obligations that may exist under the CUSIP NO. 950590109 SCHEDULE 13D/A PAGE 8 OF 10 PAGES Agreement. As a result, the Reporting Entities disclaim membership in any "group" with the Trian Entities, for purposes of Section 13(d)(3) of the Exchange Act or otherwise, and will no longer be filing a joint Statement on Schedule 13D with the Trian Entities.

On September 16, 2008, Sandell Asset Management Corp, and Trian Fund Management, L.P., entered into the Termination Agreement, terminating the parties' respective obligations under the Agreement. This description of the Termination Agreement is a summary only and is qualified by reference to the Termination Agreement, a copy of which was filed as Exhibit 23 to the Schedule 13D/A filed with the SEC by the Trian Entities on September 16, 2008 and is incorporated herein by reference. In view of the proposed acquisition of the Company by Triarc Companies, Inc., and the likelihood that this transaction will be completed regardless of any action taken by the Reporting Persons prior to the Company's next annual meeting of shareholders, the Reporting Persons have terminated the proxy granted to Trian Fund Management, L.P. pursuant to the Agreement. Each of the Reporting Entities continues to beneficially own the shares of Common Stock to which this Statement relates for investment purposes in the ordinary course of business pursuant to the investment strategies of Castlerigg Master Investments Ltd.
