Dear Brian

This letter agreement confirms our understanding that Nevada Geothermal Power, Inc. (the “Company” or “you”) has engaged Markus K. Christen (“MC” or “I”) or his affiliates, as appropriate, to act as your Exclusive Financial Advisor in the arranging of debt financing and or equity/tax equity financing, or any combination thereof (together referred to as the “Project Financing”) through a special purpose entity (les) in order to fund construction of the Company's proposed Blue Mountain geothermal project (the “Project”), located in Humboldt County, Northern Nevada. In addition, MC may act as your Non-Exclusive Financial Advisor for the purpose of assisting in arranging financing (equity/debt or tax equity) for the special purpose entity in order to fund completion of feasibility work on the Project (the “Feasibility Financing”), which shall be completed prior to the Project Financing.

The term of this engagement shall be 12 months from the date of this agreement (the “Term”), unless extended by mutual agreement in writing.

MC acknowledges that the Company has previously granted a right of first refusal to Dundee Securities Inc. to lead manage all equity offerings by the Company and to act as Its financial advisor in certain transactions, such as a sale, reorganization of similar transactions (the °Dundee ROFR"), The Company anticipates that the intended structure of the Feasibility and Project Financing will fall outside of the Dundee ROFR; however, until the final structure is determined, the parties acknowledge that the Dundee ROFR may apply to the Feasibility and Project Financing.

As part of this engagement, I will, if appropriate and requested:

(a) assist in financial structuring the Project;

(b) assist in preparation of a financing plan;

(c) solicit proposals for funding senior debt, subordinated/mezzanine debt;

(d) solicit proposals for equity/tax equity;

(e) assist in the evaluation of such proposals;

(f) assist in structuring, negotiation and documentation.

In connection with MC's engagement, the Company will furnish MC with all information concerning the Company and any companies through which the Project is to be carried out (the Project Companies") which MC reasonably deems appropriate and will provide MC with access to the officers, directors, employees, accountants, counsel and other representatives (collectively, the "Representatives"), It being understood that MC will rely solely upon such information supplied by the Project Companies and their Representatives without assuming any responsibility for independent Investigation or verification thereof. All non-public information concerning the Project Companies given to MC will be used solely In the course of the performance of the services hereunder and will be treated confidentially for so long as it remains non-public. Except as otherwise required by few or judicial or regulatory process, MC wilt not disclose this Information to a third party without the consent of the Company.

As compensation for services hereunder, the Company agrees to pay MC as follows:

(a) financial advisory fees for services rendered at an hourly rate of US $200 per hour, subject to a daily maximum fee of US $1,000 per travel day, a daily maximum fee of US $1,600 per standard business day, and a monthly maximum fee- of US$12,500 per month (the "Service Fees"). One-Half of all Service Fees shall be credited against any Transaction Fee paid out as described in section (b) below.

(b) In connection with the Project Financing a success fee, (the "Transaction Fee"). Such Transaction Fee shall be the higher of US$500’000 and the sum of:(i) 4% of the amount of any equity placement (including drilling expenditures, accelerated depreciation, investment tax credits and depletion allowance) or sub debt/mezzanine debt; and (ii) 0.50% of the amount of any senior debt financing arranged; and (iii) 1% of production tax credit financing.

(c) In connection with the Feasibility Financing, the Company shall pay fees to MC In consideration for funding provided by investors introduced to the Company, calculated, depending of the form of such financing, at the rates described in sub-section (b) above, provided that the US$500,000 minimum fee shall not apply to Feasibility Financing. In the event that funding is provided through the efforts of another agent working with MC, then MC shall negotiate in good faith an equitable fee sharing arrangement with such agent. 

(d) In addition, the Company agrees to reimburse MC monthly for all reasonable out-of-pocket expenses.

All fees and expenses payable hereunder are net of all applicable withholding and similar taxes. it is understood that the consultant wilt be responsible for making any end all remittances required by law or with respect to taxation, unemployment Insurance, pension contributions or any other matters.

For purposes of this agreement, the "Transaction Fee" shall become due and payable when the Company signs project documentation for the Project Financing of the Project and shall be paid from the first drawdown. For the purposes of this engagement the term "Project Financing' shall include, without limitation, any (whether in one or a series of transactions) investment(s) of a third party in the assets or capital stock of any Project Company. In the event that MC should arrange Project Financing from an existing contact of the Company (such contacts being listed on Annex B) then MC agrees that the 4% Transaction Fee for equity placement or sub debt/mezzanine debt shall be reduced to 3%.

No advice rendered by MC, or a reference to MC, whether formal or informal, may be disclosed, in whole or In part, or summarized, excerpted from or otherwise referred to without our prior written consent, unless such disclosure is required to be made by the Company in order to comply with the applicable securities regulatory disclosure obligations of the Company, If requested by MC, the Company shall Include a mutually acceptable 

reference to MC in any press release or other public announcement made by the Company regarding the matters described in this letter.

Dear
  Brian

As
  you requested by you, I am working on a financing, which shall bridge the time
  between when an acceptable GeothermEx Report is available and when all the construction
  permits for the Blue Mountain project will be in place and the construction
  financing will be available. Such financing will give NGP the flexibility and
  necessary liquidity to continue the development process for Blue Mountain expeditiously
  and without interruption.

The
  engagement letter, dated January 12, 2007 addresses 3 different levels of fees
  payable in connection different financing Instruments;

i) 4% for equity or mezzanine debt

ii) 1% for PTC financing and

iii) 0.5% for senior
  debt financing.

The
  anticipated source of financing identified does not fit any of the three levels
  originally anticipated in the pure sense of its definitions. It gives NGP access
  to funds at the time when it only could be accessed through and instrument under
  i) above, but technically it will not be defined as equity or mezzanine debt
  I would like to clarify the situation and amend the Engagement Letter as follows:

Paragraph
  (b) shall be replaced by new paragraph (b)

(b)
  [old] in connection with the Project Financing a success fee, (the "Transaction
  Fee"). Such Transaction Fee shall be the higher of US$500'000 and the sum
  of:(i) 4% of the amount of any equity placement (including drilling expenditures,
  accelerated depreciation, investment tax credits and depletion allowance) or
  sub debt/mezzanine debt; and (ii) 0.50% of the amount of any senior debt financing
  arranged; and (Ili) 1% of production tax credit financing.

(b)
  [new] in connection with the Project Financing a success fee, (the "Transaction
  Fee). Such Transaction Fee shall be the higher of US$500'000 and the sum of:(i)
  4% of the amount of any equity placement (including drilling expenditure, accelerated
  depreciation, investment tax credits and depletion allowance) or sub debt/mezzanine
  debt; and (ii) 0.50% of the amount of any senior debt financing arranged; (iii)
  1% of production tax credit financing and (iv) 2% of any Bridge Financing.

  

Please
  review and if acceptable please execute and send back to me.
