OTHER EVENTS On November 12, 2002, the Company announced that it had signed into an Agreement and Plan of Merger (the "Merger Agreement") with Monmouth Acquisition Corp., a Delaware corporation and a wholly-owned subsidiary of the Company ("MergerCo") and H Power pursuant to which, H Power will be merged with and into MergerCo (the "Merger"). Under the terms of the Merger Agreement, the Company will acquire H Power in a stock-for-stock exchange valued at approximately $50.7 million. The exchange ratio is initially set at approximately eight-tenths of a share of the Company for each H Power share. Based on this initial exchange ratio, H Power shareholders would receive shares of common stock of the Company equaling approximately $4.70 per share for each H Power share. The initial exchange ratio will vary within upper and lower bounds of 10% in the event that the value of Company common stock during a defined pre-closing period varies by more than 10% from $5.88 per share. In addition, the value to be paid will vary depending on the amount of H Power's cash, assets and liabilities at the closing date. The Merger is subject to customary closing conditions and regulatory approvals, as well as the approval of the stockholders of the Company and H Power. The Company also entered into voting agreements with H. Frank Gibbard, the Chief Executive Officer of H Power, Arthur Kaufman, the Chief Technology Officer of H Power, and ECO Fuel Cells, LLC ("ECO"). Pursuant to the voting agreements, such stockholders have agreed to vote their H Power shares in favor of the Merger. In addition, the voting agreements contain provisions regarding restrictions on selling or otherwise disposing of Company common stock received by such stockholders in the Merger. The voting agreement with ECO, however, does not contain such restrictions. A copy of the Merger Agreement and the form of voting agreement are attached to this Current Report on Form 8-K as Exhibit 2.1 and 99.1, respectively, and are incorporated herein by reference. A copy of the joint press release of the Company and H Power, dated November 12, 2002, issued in connection with the execution of the Merger Agreement is also filed as an exhibit hereto and is incorporated herein by reference.
