A.

WHEREAS, Lessee and Nevada Land & Resource Company, LLC ("NLRC") entered into a Geothermal Lease Agreement having an effective date of March 31, 2003 (as amended by the Pre-Sale Amendments, the "Agreement"), whereby NLRC granted Lessee the right to explore and develop Geothermal Resources on, among other parcels of real property, the property described on Exhibit "A" attached hereto and incorporated herein (the "Property"), which Agreement was (a) disclosed of record by that certain Memorandum of Geothermal Lease #189093 recorded on April 23, 2003 in the Official Records of Humboldt County, Nevada as Document No. 2003-2346 and (b) amended by each of the following amendments (collectively, the "Pre-Sale Amendments"):

C.

WHEREAS, NLRC and Lessee have subsequently entered into amendments (the "Post­-Sale Amendments") extending the term of the Agreement; and





D.

WHEREAS, the parties hereto wish to amend the terms of the Agreement insofar as they apply to Landowner, Lessee and the Property, to extend the term of the Agreement to coincide with the Post-Sale Amendments,



NOW, THEREFORE, for good and valuable consideration, the receipt of which is hereby acknowledged, the parties hereto agree as follows:



1.

Capitalized terms used and not defined herein shall have the meaning given the same in the Agreement.

2.

Section 3 of the Agreement is hereby deleted in its entirety and replaced by the following:



"Term:The initial term of this Agreement shall commence on March 31, 2003 and shall expire on March 30, 2013, unless this Agreement is sooner terminated, cancelled or extended, Landowner grants to Lessee and Lessee shall have the option and the right to extend the term of this Agreement in each of the following circumstances:



(a)

for ten (I 0) additional extension terms of one (1) year each on the express condition that Lessee is actively conducting exploration and development activities on the Property at the expiration of the term immediately preceding the proposed extension term. If Lessee elects to extend the term of this Agreement, Lessee shall notify Landowner not less than thirty (30) days before expiration of the term immediately preceding the proposed extension term; and



(b)

for ten (10) additional extension terms of five (5) years each on the express condition that Lessee is conducting production activities on the Property at the expiration of the term immediately preceding the proposed extension term. If Lessee elects to extend the term of this Agreement, Lessee shall notify Landowner not less than thirty (30) days before expiration of the term immediately preceding the proposed extension term.



Failure of Lessee to provide notice under subparagraphs (a) and (b) above shall constitute an irrevocable waiver by Lessee of the extension rights provided under this Section 3 and shall result in termination of this Agreement immediately at the expiration of the then current term without any ability to restore such extension rights."



For purposes of such amended Section 3, the term "Landowner" shall have the meaning given in this Amendment.



3.

As between Landowner and Lessee, and insofar as it relates to the Property, references in the Agreement, as amended hereby, to "NLRC" shall be deemed references to Landowner.



4.

Landowner and Lessee hereby ratify, approve and adopt the Agreement as amended hereby, and agree that the Agreement, as amended hereby, is in good standing and in full force and effect as between Landowner and Lessee. Without limiting the generality of the foregoing, the Pre- Sale Amendments are hereby ratified, approved and adopted by the parties hereto and, if and to the extent that any such Pre-Sale Amendments were incorrectly or partially executed by any party thereto (including by virtue of naming an affiliate of either such party as a party to such Pre-Sale Amendments rather than naming the Landowner or Lessee thereunder directly), Landowner and Lessee hereby ratify, adopt and approve such Pre-Sale Amendments, and agree to be bound by all the terms and provisions thereof. In addition, notwithstanding that the partial assignment described in Recital B refers to a lease dated May 1, 1986 and identifies an affiliate of Lessee as the lessee under the Agreement, the parties acknowledge and agree that such partial assignment pertains to the Agreement.
