Item 2. Identity and Background. (a) This statement is filed by: (i) Eminence Partners, LP, a New York limited partnership ("Eminence I"), with respect to the shares of Common Stock directly owned by it; (ii) Eminence Partners II, LP, a New York limited partnership ("Eminence II" and together, with Eminence I, the "Partnerships"), with respect to the shares of Common Stock directly owned by it; (iii) Eminence GP, LLC, a New York limited liability company ("Eminence GP"), which serves as General Partner to the Partnerships, with respect to the shares of Common Stock directly owned by the Partnerships; (iv) Eminence Capital, LLC, a New York limited liability company (the "Investment Manager"), which serves as the investment manager to the Partnerships and Eminence Fund, Ltd., a company organized under the laws of the Cayman Islands ("Eminence Offshore"), with respect to the shares of Common Stock directly owned by the Partnerships and Eminence Offshore; and (v) Ricky C. Sandler, with respect to the shares of Common Stock directly owned by the Partnerships, Eminence Offshore and certain other accounts. The foregoing persons are hereinafter sometimes collectively referred to as the "Reporting Persons." Any disclosures herein with respect to persons other than the Reporting Persons are made on information and belief after making inquiry to the appropriate party. (b) The address of the principal business and principal office of the Partnerships, Eminence GP and the Investment Manager is 65 East 55th Street, 25th Floor, New York, NY 10022. The business address of Mr. Sandler is 65 East 55th Street, 25th Floor, New York, NY 10022. (c) The principal business of the Partnerships is serving as private investment limited partnerships. The principal business of Eminence GP is serving as a general partner to the Partnerships. The principal business of the Investment Manager is that of an investment manager engaging in the purchase and sale of securities on behalf of clients. Mr. Sandler serves as the Managing Member of Eminence GP and the Investment Manager. CUSIP No. 575384102 13D Page 8 of 18 pages (d) None of the Reporting Persons has, during the last five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors). (e) None of the Reporting Persons has, during the last five years, 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. (f) The Partnerships are limited partnerships organized under the laws of the State of New York. Each of Eminence GP and the Investment Manager is a limited liability company organized under the laws of the State of New York. Mr. Sandler is a United States citizen. Item 3. Source and Amount of Funds and Other Consideration. The net investment cost (including commissions, if any) of the shares of Common Stock directly owned by the Partnerships, Eminence Offshore and the certain other accounts is approximately $115,400,000. Mr. Sandler, Eminence GP and the Investment Manager do not directly own any shares of Common Stock. Item 4. Purpose of the Transaction. The purpose of the acquisition of the shares of Common Stock by the Reporting Persons is for investment, and the purchases of the shares of Common Stock by the Reporting Persons were made in the ordinary course of business and were not made for the purpose of acquiring control of the Company. Although the acquisition of the shares of Common Stock by the Reporting Persons is for investment purposes, the Reporting Persons have had discussions with management in an effort to maximize long-term value for shareholders. Previously, the Reporting Persons had objected to, and have voted their proxy against, the proposed sale of Masonite to KKR (the "Transaction"). On February 17, 2005 (two days after the last purchase of Masonite stock by the Reporting Persons) KKR contacted a representative (the "Representative") of the Reporting Persons seeking support for the Transaction. In that discussion KKR had asked at what price the Reporting Persons would support the Transaction. The Representative told KKR that the Reporting Persons would support a transaction at a price no less than CAD $42.25. No understandings or agreements of any kind were entered into as a result of that conversation. Subsequently, KKR contacted the Representative and indicated they would modify the Transaction price to CAD $42.25 per share if the Reporting Persons agreed, in writing, to vote their proxy in favor of the Transaction. The Representative has in turn entered into an agreement with KKR to support the Transaction at CAD $42.25 and to vote their proxy in favor of the Transaction. In the event the Transaction is voted down at the March 31, 2005 special meeting of shareholders or the Transaction is terminated for any reason the Reporting Persons intend to continue discussions with the management of Masonite regarding how they may maximize the long-term value for shareholders.
