("MacAndrews & Forbes") today announced that they have entered into a definitive merger agreement under which MFW will be merged with a subsidiary of MacAndrews & Forbes and all outstanding shares of MFW common stock not owned by MacAndrews & Forbes will be converted into the right to receive $25 in cash per share. MacAndrews & Forbes currently owns approximately 43% of the outstanding shares of MFW common stock. The cash consideration represents a greater than 47% premium to the Company's closing share price on June 10, 2011, the last trading day prior to MacAndrews & Forbes' announcement of its proposal to acquire the shares of MFW common stock that it did not already own and a greater than 22% premium to the Company's closing share price on September 9, 2011, the last trading day prior to today's announcement of the execution of a definitive merger agreement.

The transaction was approved by the board of directors of MFW, upon the recommendation and approval of a special committee comprised entirely of independent directors that was formed to evaluate and consider the transaction. The special committee's recommendation and approval followed a thorough examination of the transaction, which occurred over a three-month period. Evercore Group L.L.C. acted as financial advisor and Willkie Farr & Gallagher LLP acted as legal counsel to the special committee. Moelis & Company acted as financial advisor and Skadden, Arps, Slate, Meagher & Flom LLP acted as legal counsel to MacAndrews & Forbes.

The transaction is subject to the receipt of regulatory approvals and other customary closing conditions. The transaction is also subject to a non-waivable condition that a majority of the outstanding shares of MFW common stock not owned by MacAndrews & Forbes or its directors and officers vote in favor of the adoption of the merger agreement. MacAndrews & Forbes has agreed to vote the shares of MFW common stock it owns in favor of the merger agreement. The transaction is not subject to any financing contingency.

The transaction is expected to close during the fourth quarter of 2011, subject to the review and clearance of required filings by the Securities Exchange Commission ("SEC").
