On March 23, 2009, Domino’s Pizza, Inc. (“Domino’s” or the “Company”) filed a Definitive Proxy Statement for the Annual Meeting of Stockholders of Domino’s to be held on April 28, 2009 (the “Proxy Statement”), which, among other things, contains a proposal submitted to the Company’s shareholders to approve a stock option exchange program (the “Proposed Option Exchange Program”) for all current employees of the Company who hold outstanding options that satisfy the conditions specified for the Proposed Option Exchange Program. The Company subsequently filed a Schedule TO (the “Schedule TO”) on March 24, 2009 relating to the Proposed Option Exchange Program that included as an exhibit, among other items, the Offering Memorandum (the “OM”) relating to the Proposed Option Exchange Program.

On April 10, 2009, in response to comments received from the Securities and Exchange Commission relating to the Schedule TO and the terms of the Proposed Option Exchange Program, Domino’s filed Amendment No. 1 to the Schedule TO in order to make certain modifications to the terms of the Proposed Option Exchange Program. Under the terms of the Proposed Option Exchange Program as revised by Amendment No. 1 to the Schedule TO, Domino’s will determine the exercise price and the number of shares underlying the replacement option grants based upon the closing price of Domino’s common stock on the New York Stock Exchange on the business day immediately preceding the expiration date of the tender offer, rather than on the expiration date of the tender offer. As a result, based upon the current terms of the tender offer, the exercise price and the number of shares underlying the replacement option grants will be determined on Friday May 1, 2009, rather than on Monday May 4, 2009, which remains the expiration date for the tender offer.
