Unregistered Sale of our Common Stock

On October 22, 2007, we agreed to issue 1,105,004 shares of common stock in a transaction complying with the requirements of Regulation S under the Securities Act of 1933 to our parent, Ormat Industries, for an aggregate purchase price of approximately $50.7 million, which was determined based on the public offering price in this offering minus underwriting discounts and commissions. Closing of the transaction was expected to occur concurrently with the closing of this offering, subject to certain customary closing conditions, including the closing of this offering. In order to ensure compliance with rules of the New York Stock Exchange, we have agreed with Ormat Industries to reduce the number of shares of common stock being sold in the unregistered transaction to 381,254, for an aggregate purchase price of $17.5 million. All other terms and conditions of the transaction will remain the same, including the price per share to be paid by Ormat Industries.

As a result of the decision to reduce the number of shares to be sold to Ormat Industries in the unregistered transaction, we have amended certain sections of the Prospectus Supplement we filed on October 23, 2007. These changes relate to: (i) the amount of proceeds we will receive in the unregistered transaction and (ii) the number of shares of our common stock that will be outstanding after the completion of the unregistered sale and this public offering.
