In addition, pursuant to a Letter Agreement among the Company, Evergreen Clean Energy, LLC ("Evergreen"), and Raser Power Systems, LLC ("Raser Power"), dated October 27, 2010 (the "Letter Agreement"), Evergreen agreed to advance certain funds to the Company from time to time, including an initial advance of $1,150,000 on October 28, 2010. As additional consideration for the Letter Agreement, the Company and Raser Power agreed not to solicit additional potential purchasers for the purchase of any interests in Thermo on or before November 30, 2010, and agreed to pay a break-up fee in certain circumstances.    The Company's obligation to repay the initial advance of $1,150,000 was made pursuant to a Secured Promissory Note, dated October 28, 2010, issued by the Company to Evergreen (the "Secured Promissory Note"). The terms of the Secured Promissory Note allow for the Company to receive advances from Evergreen in one or more loans (each, a "Loan" and collectively, the "Loans") for up to $2,500,000. Principal and accrued interest on all Loans shall be payable to Evergreen on the earlier of June 30, 2011 or the date on which the Company closes a transaction for the sale of its Thermo No. 1 Plant ("Maturity Date"). The Loans bear interest at the rate of twelve percent (12%) per annum or, with respect to any amounts not paid to Evergreen by the Maturity Date, at the rate of eighteen percent (18%) per annum. The Company's obligations under the Secured Promissory Note are secured by a first priority security interest in, and lien on all of the Company's right, title, and interest in its Alvord prospect (formerly the Borax Lake prospect) located in Harney County, Oregon and certain transformer equipment, pursuant to the Deed of Trust and Security Agreement, dated October 28, 2010, executed by Raser Power for the benefit of Evergreen (the "Deed of Trust") and the Security Agreement, dated as of October 28, 2010, between Raser Power and Evergreen (the "Security Agreement").
