LETTER OF INTENT This Letter of Intent dated May 2, 1997 sets forth the terms and conditions of the proposed series of two linked transactions. The first transaction (the "Stock Purchase") is the purchase by The UB Group, One Harbor Drive, Suite 102, Sausalito, CA 95965 of an equity interest in Mendocino Brewing Company, Inc. ("Mendocino") located at 13351 South Highway 101, Hopland, CA 95449-0400. The purchaser may be The UB Group or a corporation controlled by Mr. Vijay Mallya, Chairman of The UB Group (the "Purchaser"). The second transaction (the "Merger") is the proposed merger of Mendocino into a publicly traded affiliate of Purchaser in a related transaction. A. THE INVESTMENT - SECURITIES TO BE PURCHASED AND PURCHASE PRICE 1. At the closing of the Stock Purchase (the "Closing"), which will be simultaneous with the execution of definitive documents, Purchaser will purchase preferred and/or common equity securities in Mendocino (the "Securities") and the purchase price for the Securities will consist of between $3,000,000 to $4,000,000, payable in cash upon Closing and as adjusted for the creditable refundable deposit described in Section F.7. The exact amount of the investment within the prescribed range will be determined during Purchaser's due diligence through an assessment of Mendocino's cash flow needs through December 31, 1997 as mutually agreed to between Purchaser and Mendocino. The cash price per share for the purchased Securities is set to $4.50 as warranted by performance versus 1996, but not less than $4.00. B. THE PROPOSED MERGER - MENDOCINO AND UCB 1. It is the intention of the Parties that at a later stage, but no later than September 30, 1997, Mendocino should merge into United Craft Brewers, Inc. ("UCB"), a corporation to be formed by The UB Group and listed on NASDAQ. UCB will be a holding company for various constituent corporations ("Subsidiaries") involved in the business of brewing and selling craft beers. The merger will take place on the basis of a conversion factor based upon the relative valuations, relating to then prevailing market prices of their respective listed shares, or such other basis to be agreed upon, together with other reasonable mutually agreed terms. There will be appropriate non-manipulation covenants. The Purchaser and the Original Partners agree to exercise their voting power to approve the merger. C.
