You have advised us that you intend to finance the Transaction and the costs and expenses related to the Transaction (as hereinafter defined) from the following sources: (a) an equity contribution representing no less than $23 million of development costs in respect of the Project will have been contributed prior to the Closing Date (the Equity Financing) to the Borrower by you and your affiliates and (b) senior bank debt in the form of a construction loan facility (the Credit Facility) with a principal amount up to $100 million or, in the event that the Tax Investor referred to in the Summary of Terms has agreed to increase its commitment above $100 million, an amount equal to such higher equity commitment; provided that the principal amount of the Credit Facility shall not exceed $115 million.  The Equity Financing and the entering into and funding of the Credit Facility and all related transactions are hereinafter collectively referred to as the Transaction.

1.

Commitments.  In connection with the foregoing, (a) each of MSSF and Glitnir is pleased to advise you of its commitment to severally (and not jointly) provide 50% of the principal amount of the Credit Facility and (ii) MSSF is pleased to advise you of its commitment to act as the sole and exclusive administrative agent (in such capacity, the Administrative Agent) for the Credit Facility, all upon and subject to the terms and conditions set forth in this letter and in the summary of terms attached as Annex I (collectively, the Summary of Terms and, together with this letter agreement, the Commitment Letter), and (b) each of MS&Co and Glitnir is pleased to advise you of its willingness to act, as arranger and book running manager (with MS&Co having left side designation) (in such capacity, the Joint Lead Arrangers) for the Credit Facility, and to use commercially reasonable efforts to form a syndicate of financial institutions and institutional lenders (collectively, the Lenders) in consultation with you for the Credit Facility. It is a condition to each of Glitnirs and MSSFs commitment hereunder that sufficient funding is available for the construction of the Project at Closing. All capitalized terms used and not otherwise defined herein shall have the same meanings as specified therefor in the Summary of Terms.  If you accept this letter as provided below in respect of the Credit Facility, the date of the initial funding under the Credit Facility is referred to herein as the Closing Date.

2.

Syndication.  The Joint Lead Arrangers intend to commence syndication of the Credit Facility at a time in their discretion after your acceptance of the terms of this Commitment Letter and the Fee Letters, and the commitments of MSSF and Glitnir hereunder, as applicable, related to the Credit Facility shall be reduced dollar-for-dollar on a pro rata basis as and when corresponding commitments are received from the Lenders.  You agree to actively assist, and to cause the Borrower to actively assist, the Joint Lead Arrangers in achieving a syndication of the Credit Facility that is satisfactory to the Joint Lead Arrangers.  Such assistance shall include (a) your providing and causing your advisors to provide the Joint Lead Arrangers and the Lenders upon request with all information reasonably deemed necessary by the Joint Lead Arrangers to complete such syndication, including, but not limited to, information and evaluations prepared by you, the Borrower and your and its advisors, or on your or their behalf, relating to the Transaction, (b) your assistance in the preparation of an Information Memorandum to be used in connection with the syndication of  the Credit Facility, (c) your using your best efforts to ensure that the syndication efforts of the Joint Lead Arrangers benefit materially from your existing lending relationships and the existing lending relationships of the Borrower and (d) your otherwise assisting the Joint Lead Arrangers in their syndication efforts, including by making your officers and advisors and the officers and advisors of the Borrower available from time to time to attend and make presentations regarding the business and prospects of the Borrower, as appropriate, at one or more meetings of prospective Lenders.

It is understood and agreed that the Joint Lead Arrangers will manage and control all aspects of the syndication of the Credit Facility, including decisions as to the selection of prospective Lenders and any titles offered to proposed Lenders, when commitments will be accepted and the final allocations of the commitments among the Lenders.  It is understood that no Lender participating in the Credit Facility will receive compensation from you in order to obtain its commitment, except on the terms contained herein and in the Summary of Terms. It is understood that the Morgan Stanley name will appear to the left of the name of any other Joint Lead Arranger, agent or arranger on any Information Memorandum or other document related to the Facility.

It is also understood and agreed that the amount and distribution of the fees among the Lenders will be at the sole discretion of the Joint Lead Arrangers. It is further understood that all Lenders participating in the Credit Facility will sign confidentiality agreements in form and substance similar to the confidentiality agreement signed by MSSF and Glitnir in connection with the Power Purchase Agreement with Nevada Power Company, dated August 18, 2006.

3.

Information Requirements.  You hereby represent, warrant and covenant that (a) all information, other than Projections (as defined below), that has been or is hereafter made available to MSSF, the Joint Lead Arrangers or any of the Lenders by you or any of your representatives (or on your or their behalf) or by the Borrower or any of its representatives (or on their behalf) in connection with any aspect of the Transaction (the Information) is and will be complete and correct in all material respects and does not and will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein not misleading and (b) all financial projections concerning the Borrower that have been or are hereafter made available to MSSF, the Joint Lead Arrangers or any of the Lenders by you or any of your representatives (or on your or their behalf) or by the Borrower or its representatives (or on its behalf) (the Projections) have been or will be prepared in good faith based upon reasonable assumptions.  You agree to furnish us with such Information and Projections as we may reasonably request and to supplement the Information and the Projections from time to time until the Closing Date so that the representation, warranty and covenant in the immediately preceding sentence is correct on the Closing Date.  In issuing this commitment and in arranging and syndicating the Credit Facility, Morgan Stanley, Glitnir and their respective affiliates are and will be using and relying on the Information and the Projections without independent verification thereof.

You hereby acknowledge that (a) MSSF and Glitnir will make available Information and Projections (collectively, Borrower Materials) to the proposed syndicate of Lenders by posting the Borrower Materials on IntraLinks or another similar electronic system (the Platform) and (b) certain of the proposed Lenders may be public-side Lenders (i.e., Lenders that do not wish to receive material non-public information with respect to the Borrower or its securities) (each, a Public Lender).  You hereby agree that (w) you will use commercially reasonable efforts to identify that portion of the Borrower Materials that may be distributed to the Public Lenders and include a reasonably detailed term sheet among such Borrower Materials and that all Borrower Materials that are to be made available to Public Lenders shall be clearly and conspicuously marked PUBLIC which, at a minimum, shall mean that the word PUBLIC shall appear prominently on the first page thereof; (x) by marking Borrower Materials PUBLIC, you shall be deemed to have authorized MSSF and the proposed Lenders to treat such Borrower Materials as not containing any material non-public information with respect to the Borrower or its securities for purposes of United States federal and state securities laws, it being understood that certain of such Borrower Materials may be subject to the confidentiality requirements of the definitive credit documentation; (y) all Borrower Materials marked PUBLIC are permitted to be made available through a portion of the Platform designated Public Investor; and (z) the Joint Lead Arrangers shall be entitled to treat any Borrower Materials that are not marked PUBLIC as being suitable only for posting on a portion of the Platform not designated Public Investor.

4.

Fees and Indemnities.  You agree to reimburse each of the Joint Lead Arrangers from time to time on demand for all reasonable out-of-pocket fees and expenses (including, but not limited to, the reasonable fees, disbursements and other charges of counsel to the Joint Lead Arrangers and the Administrative Agent, and of any special and local counsel to the Lenders retained by the Joint Lead Arrangers, and due diligence expenses) incurred in connection with the Credit Facility, the syndication thereof, the preparation of the definitive documentation therefor and the other transactions contemplated hereby.

You also agree to indemnify and hold harmless Morgan Stanley, Glitnir, each other Lender and each of their affiliates and their officers, directors, employees, agents, advisors and other representatives (each an Indemnified Party) from and against (and will reimburse each Indemnified Party as the same are incurred for) any and all claims, damages, losses, liabilities and expenses (including, without limitation, the reasonable fees, disbursements and other charges of counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or by reason of (including, without limitation, in connection with any investigation, litigation or proceeding or preparation of a defense in connection therewith) (a) any aspect of the Transaction or any similar transaction and any of the other transactions contemplated thereby or (b) the Credit Facility and any other financings, or any use made or proposed to be made with the proceeds thereof, except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Partys gross negligence or willful misconduct.  In the case of an investigation, litigation or proceeding to which the indemnity in this paragraph applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by you, your equity holders or creditors or an Indemnified Party, whether or not an Indemnified Party is otherwise a party thereto and whether or not any aspect of the Transaction is consummated.  You also agree that no Indemnified Party shall have any liability (whether direct or indirect, in contract or tort or otherwise) to you or your subsidiaries or affiliates or to your or their respective equity holders or creditors arising out of, related to or in connection with any aspect of the Transaction, except only for (a) direct (as opposed to special, indirect, consequential or punitive) damages determined in a final non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Partys gross negligence or willful misconduct and (b) that each Lender shall remain liable to you (and only to you) severally in respect solely of its own commitment in respect of the Credit Facility and not jointly, for direct, as opposed to special, indirect, consequential or punitive, damages determined in a final non-appealable judgment by a court of competent jurisdiction to have been caused by breach of its obligations hereunder to negotiate in good faith definitive documentation for the Credit Facility on the terms set forth herein.

5.
