The acquisition was effected through a merger (the "Merger") of Monmouth Acquisition Corp. with and into H Power, with H Power surviving the Merger as a wholly-owned subsidiary of Plug Power. Based upon the factors discussed in the Merger Agreement which were utilized to determine the exchange ratio, each share of H Power common stock, par value $0.001 per share ("H Power Common Stock"), outstanding immediately prior to the effective time of the Merger is entitled to receive .8305 shares of Plug Power common stock, par value $0.01 per share ("Plug Power Common Stock"). Any holder of H Power Common Stock who would otherwise be entitled to receive a fraction of a share of Plug Power Common Stock will instead receive an amount of cash equal to the product of such fraction and $5.08. Approximately 8.95 million shares of Plug Power Common Stock will be issued in the Merger, bringing the total number of shares of Plug Power Common Stock outstanding immediately following the Merger to 60.0 million. Plug Power will issue the shares of Plug Power Common Stock out of its authorized but unissued shares and will issue the cash in lieu of fractional shares from its general working capital. The Merger is being accounted for as a purchase transaction for accounting purposes. The Merger Agreement was negotiated at arm's length between representatives of Plug Power and representatives of H Power. Neither Plug Power nor any officer or director of Plug Power was affiliated with or had a material relationship with H Power.
