NEW YORK, Sept. 7 /PRNewswire/ -- Pershing Square Capital Management, L.P. announced today that it is sending the following letter to Ceridian stockholders: "Dear Fellow Ceridian Stockholder: We are pleased with Ceridian's recent commitment that if the merger does not close, the company will hold a new election of directors within 90 days after the merger agreement is terminated. In light of Ceridian's commitment, we no longer feel the need to nominate a full slate at the company's upcoming annual meeting. However, we note that under the terms of the company's commitment the new election could be held off until June 30, 2008 or even later depending on the circumstances. Accordingly, we plan to nominate a minority slate: John D. Barfitt, Robert J. Levenson and myself, William A. Ackman. I enclose with this letter a new BLUE proxy card that reflects this change. Our original GREEN card is no longer valid. We urge each of you to vote on the new BLUE proxy card by Internet or telephone, which will allow you to vote for the merger, for our three nominees and for all of the incumbent nominees other than Ronald T. LeMay, George R. Lewis and Alan F. White. That means you will be able to use our BLUE card by Internet or telephone to effectively vote for our three nominees as well as Ceridian's CEO and President Kathryn V. Marinello, Chairman L. White Matthews, III, and incumbent directors Richard Szafranski and William L. Trubeck.(*) Electing our three nominees will not constitute a change of control under Ceridian's compensation plans and as a result will not prematurely vest any employee grants. In addition, electing our three nominees renders moot the risks that Ceridian claims may be created if the incumbent board were replaced in its entirety: -- The buyers will continue to work opposite the same team that negotiated the transaction (including Ms. Marinello, Mr. Matthews and the company's legal and financial advisors). -- Electing our three nominees will not pose a risk to consummation of the merger. According to Institutional Shareholder Services (ISS), minority representation will "minimize the negligible risk to the deal while still providing the impetus for change if the deal fails to close."(+) Despite Ceridian's commitment, we continue to think this election contest is of critical importance. -- The 'drop-dead' date under the merger agreement can be as late as March 31, 2008 so it is possible that Ceridian could delay elections until June 30, 2008 or even longer depending on the circumstances. In our view, that is simply too long a period for the board to continue without: * a director who has a substantial equity stake in Ceridian and * two directors (Messrs. Barfitt and Levenson) who spent years serving at high level positions with ADP and First Data and therefore will be able to provide the board with substantial and directly relevant business expertise. -- In the unlikely event that the deal encounters any turbulence, we believe that stockholders would be best served if Ceridian has a board member with a substantial equity stake. Given Pershing Square's investment in Ceridian of over $700 million, we believe the election of our nominees will give stockholders greater confidence that the interests of the board and stockholders are fully aligned. Pershing Square strongly recommends that you vote "FOR" the merger and "FOR" Pershing Square nominees William A. Ackman, John D. Barfitt and Robert J. Levenson and all of the incumbent nominees other than Ronald T. LeMay, George R. Lewis and Alan F. White as soon as possible by voting the enclosed BLUE proxy card by telephone or by Internet whether or not you plan to attend the annual meeting. Instructions are on the BLUE proxy card. Time is short, please use one of the following simple methods to vote your shares: 1. Vote by Internet: Go to the website http://www.proxyvote.com/. Have your control number listed on the BLUE proxy card ready and follow the online instructions. The control number is located in the rectangular box on the right side of your BLUE proxy card. You can use the Internet to vote until 11:59 p.m., ET on September 11, 2007. 2. Vote by Telephone: Call toll-free (800) 454-8683. Have your control number listed on the BLUE proxy card ready and follow the simple instructions. You can vote by phone until 11:59 p.m., ET on September 11, 2007. Since our original GREEN card is no longer valid, you must use the BLUE proxy card to vote by telephone or Internet if you want to vote for our nominees. If we receive BLUE proxy cards that have no explicit voting instructions, we intend to vote such proxy cards "FOR" the merger, "FOR" Pershing Square nominees William A. Ackman, John D. Barfitt and Robert J. Levenson and all of the incumbent nominees other than Ronald T. LeMay, George R. Lewis and Alan F. White, "FOR" ratification of the appointment of KPMG and "FOR" adjournment if there are insufficient votes to approve the merger. However, the BLUE proxy card will also allow stockholders to vote individually on each of the proposals, including withholding authority to vote for one or more nominees. NOTE: THE GREEN CARD PREVIOUSLY SENT TO YOU IS NO LONGER VALID. WE URGE YOU TO VOTE THE ENCLOSED BLUE PROXY CARD AS PROMPTLY AS POSSIBLE BY TELEPHONE OR INTERNET. Thank you for your support.
