     Section 4. Forbearance. The Company and Raser acknowledge the existence of the Specified Defaults, including the failure of Facility Substantial Completion and Final Completion to be achieved. Subject to the terms and conditions set forth herein, throughout the period commencing on the date of this Agreement and ending on the applicable date set forth in the first sentence of Section 6 (the “Forbearance Period”), the Lenders, the Administrative Lender, the Administrative Agent and the Collateral Agent (acting at the written direction of the Administrative Lender) hereby agree to forbear from exercising any and all available default rights and remedies under the Agreement, the Notes. the Account and Security Agreement, the deeds of trust creating the Liens described in Article XI of the Account and Security Agreement, the Class B Investors Pledge Agreement and the Special Interest Investors Pledge Agreement and at applicable law as the result of the occurrence and continuance of the Specified Defaults. The Company and Raser acknowledge and agree that the foregoing agreement to forbear exercising such default rights and remedies throughout the Forbearance Period shall not constitute a waiver of the Specified Defaults or a waiver of any other Credit Agreement Event of Default or Credit Agreement Default that is not waived by Section 3 of this Forbearance Agreement, and that the Lenders, the Administrative Lender, the Administrative Agent and the Collateral Agent expressly reserve all such default rights and remedies. The Company and Raser further acknowledge and agree that the Lenders, the Administrative Lender, the Administrative Agent and the Collateral Agent may exercise any and all such default rights and remedies at any time following the earliest to occur of (a) the expiration of the Forbearance Period, (b) the occurrence during the Forbearance Period of any additional Credit Agreement Default or Credit Agreement Event of Default, other than those potential Credit Agreement Defaults or Credit Agreement Events of Default expressly waived in Section 3 of this Forbearance Agreement (including, without limitation, any default under this Forbearance Agreement), (c) any of MLE, Merrill Lynch, Pierce, Fenner & Smith Incorporated (“MLP”), UTC, the Company, Raser or any of their respective Affiliates takes any action against the Facility, any other collateral for the Advances (including, without limitation, the additional collateral described in Article XI of the Account and Security Agreement), the Company or Raser or any of its Affiliates which the Administrative Lender believes would materially adversely affect the interests of the Lenders, the Administrative Lender, the Administrative Agent or the Collateral Agent, and (d) the aggregate balance in the Security Accounts under the Account and Security Agreement being less than $175,000 at any time from February 1 through February 24, 2011 or less than $250,000 at any time thereafter (any of the events described in clause (a), (b), (c) or (d) a “Forbearance Termination Event”).

     Section 3. Amendment of Section 6 of the Forbearance Agreement. Section 6 of the Forbearance Agreement is hereby deleted and replaced as follows:

     Section 6. Sale of the Facility or the Equity Interests in the Company. The Company and Raser hereby agree to use their commercially reasonable best efforts to sell, not later than March 15, 2011 (provided, that such date shall be extended to April 15, 2011 if, not later than March 15, 2011, the Company and Raser deliver to the Administrative Lender a letter of intent, which is not subject to any financing or similar condition or contingency, with respect to a Qualifying Sale or other transaction that will result in the Lenders receiving the cash payments provided for in this Section 6), the Facility and the other collateral described in Article XI of the Account and Security Agreement as an entirety or, in the case of Raser, to use its commercially reasonable best efforts to cause the Subsidiaries of Raser that are the owners of 100% of the Equity Interests in the Company to sell all such Equity Interests as an entirety; provided, that less than all the Facility and such other collateral, or less than all such Equity Interests, may be sold in a transaction that otherwise qualifies as a Qualifying Sale (as defined below) so long as the Lenders receive a $6,750,000 cash payment and all other requirements of the fourth sentence of this Section 6 are satisfied. Any such sale shall be solely for cash in Dollars and shall be made to a solvent Person that (a) is not an Affiliate of the Company, Raser, any Member in the Company, MLE, MLP, UTC or any other Person involved in the operation or development of the Project, (b) is not described in Section 1603(g) of ARRA, or described as being ineligible to receive payments under Section 1603 of ARRA or under any guidance, terms and conditions, frequently asked questions or other materials issued by the Department of the Treasury under Section 1603 of ARRA (“Treasury Guidance”), (c) has the requisite experience and resources to operate the Facility, and (d) agrees to operate the Facility continuously as “specified energy property” as such term is defined in Section 1603(d) of ARRA, and under any Treasury Guidance, through at least March 31, 2014 (a sale to any such Person meeting the foregoing requirements being a “Qualifying Sale”). Provided that no Forbearance Termination Event has occurred and is continuing at the time of any Qualifying Sale, the Lenders and the Administrative Lender agree to instruct the Collateral Agent in writing at such time to release its Liens under the Financing Documents in respect of the Facility and the other collateral described in Article XI of the Account and Security Agreement, or in respect of the Equity Interests in the Company, as the case may be (and any other collateral for the Obligations for which the Company has requested a lien release), against (x) payment in cash in Dollars to the Lenders of (i) 60% of the Net Proceeds (as hereafter defined) and (ii) all expenses (including legal fees) of the Administrative Lender and the Agents, provided, that the aggregate amount payable pursuant to subclause (i) of this sentence shall not exceed $6,750,000, and (y) delivery to the Lenders, the Administrative Lender and the Agents of a release which shall be executed by the Company, Raser and all Members in the Company and must be acceptable to the Administrative Lender and the Agents (it being understood that a release containing the terms, mutatis mutandis, of the release set out in Section 10 of this Forbearance Agreement shall be acceptable). Upon payment, at any time prior to the occurrence of a Forbearance Termination Event and whether from the Net Proceeds of a Qualifying Sale as described above or from a cash payment from the Company or Raser, equal to $6,750,000 plus the expenses (including legal fees) of the Administrative Lender and the Agents (and regardless of whether there has been a Qualifying Sale) and delivery of the releases, described in the preceding sentence, all obligations of the Company and Raser to the Administrative Agent, the Lenders and the Agents (other than those in Article IX of the Agreement and any others that expressly surv ive repayment of the Obligations) shall be extinguished. As used in this Section 6, “Net Proceeds” shall mean the gross proceeds of the sale of the Project and the other collateral described in Article XI of the Account and Security

Agreement as an entirety, or the proceeds of the sale of all the Equity Interests in the Company as an entirety, as the case may be, less the normal and customary costs of selling the foregoing (with brokerage commissions not to exceed 3% of the sales price and which may be payable only to Persons that are not Affiliates of the Company, Raser, any Member in the Company, MLE or any other Person involved in the operation or development of the Project). Normal and customary closing costs shall consist of any legal and professional fees and, in the case of the sale of the Facility and the other collateral described in Article XI of the Account and Security Agreement, premiums for a policy of owners’ title insurance but shall not include the payment of any Debt or of any obligation secured by a Lien against the asset being sold. The provisions of this Section 6 are in consideration for the amendments, consents, waivers forbearances and other agreements under this Forbearance Agreement, and such provisions shall not be deemed to create a joint venture, partnership or other joint ownership arrangement or relationship between the Lenders (including the Administrative Lender) and the Agents, on the one hand, and the Company, Raser and the Members in the Company on the other hand, and in no event do the parties intend, and in no event shall such provisions or any other portion of this Forbearance Agreement or any other Transaction Document be construed, to be an agreement by the Lenders (including the Administrative Lender) or the Agents to share in any operating or other losses or costs incurred by the Company, Raser or the Members in the Company or to be responsible, in any manner or to any extent, for any liabilities of the Company, Raser or the Members of the Company to any third party.
