Dear Mr. Misseldine:

	 






The Blue Mountain Unit Agreement, Humboldt County, Nevada is approved the date of this letter and is numbered N-82457X. As requested, the effective date of the Unit Agreement is June 1, 2006.

The request-for-approval package contained evidence that all lands in the unitized area are committed to the Unit Agreement which gives the unit operator, Nevada Geothermal Power Company, effective operational control of the Unit area.

Two changes from the model unit agreement language are accepted. Article 11.4 is revised to allow the drilling and completion of temperature gradient and observation wells within the first 24 month period of the effective date of this Unit. Within 36 months of the effective date of this Unit, the Unit Operator will commence drilling the initial unit well to a depth of not less than 2,500 feet. Articles 4.3, 4.5, 4.6 and 11.6 are revised to allow the period between the drilling of subsequent unit wells to be extended to six months.

Approval of this Unit Agreement does not warrant or certify that the Unit Operator thereof and other holders of operating rights hold legal or equitable title to those rights in the subject leases which are committed hereto.

One copy of the Unit Agreement is enclosed as requested. Please notify all interested parties of this action.




		
	 
	Sincerely,

Unit Agreement for the Development and Operation of the Blue Mountain Unit Area

County of Humboldt, State of Nevada




11.4

The Unit Operator shall conduct a progressive and reasonably continuous development program, approved by the authorized officer through successive Plans of Operation, until wells have been drilled that indicates that the geothermal resource can be produced in paying quantities (that is, quantities sufficient to repay the costs of drilling, completing, and producing operations, with a reasonable profit). The Unit Operator shall, at a minimum:




(a)

drill and complete additional temperature gradient and observation wells with a minimum cumulative total footage of no less than 2,000 feet within eighteen (18) months of the effective date of this Agreement. Each hole's total depth will qualify toward the 2,000 foot total (unless the Unit Operator can establish to the satisfaction of the authorized officer that drilling to such depth would be unwarranted or impracticable).

(b)

drill and complete wells with a combined drilled footage of no less than 7,500 feet within twenty-four (24) months of the effective date of this Agreement. Each development's total depth will qualify towards the 7,500 foot total footage (unless the Unit Operator can establish to the satisfaction of the authorized officer that drilling to such depth would be unwarranted or impracticable).

In any event, within thirty-six (36) months of the effective date of this Agreement, the Unit Operator shall commence the drilling of development wells to a depth of no less than 2,500 feet for each well, unless on such effective date a well is being drilled conformably with the terms, hereof, and thereafter continue such drilling diligently until unitized substances shall be discovered at or below this depth which can be produced in paying quantities (i.e., quantities sufficient to repay the costs of drilling, completing, and producing operations, with a reasonable profit) or the Unit Operator shall at any time establish to the satisfaction of the authorized officer that further drilling of said well would be unwarranted or impracticable, provided, however, that the Unit Operator shall not in any event be required to drill said well to a depth in excess of 4,500 feet.

11.5 

The initial Plan of Operation and/or subsequent Plans of Operation submitted under this Article shall provide that the Unit Operator shall initiate a continuous drilling program providing for drilling of no less than one well at a time, and allowing no more than six (6) months time to elapse between completion and testing of one well and the beginning of the next well, until a well capable of producing Unitized Substances in paying quantities is completed to the satisfaction of the authorized officer or until it is reasonably proved that the Unitized Land is incapable of producing Unitized Substances in paying quantities in the formations drilled under this Agreement.

11.6 

The authorized officer may modify the drilling requirements of this Article by granting reasonable extensions of time when, in his opinion, such action is warranted.

11.7

 Until a well is capable of producing Unitized Substances in paying quantities is completed, the failure of Unit Operator to timely drill any of the wells provided for in Plans of Operation required under this Article XI or to timely submit an acceptable subsequent Plan of Operation, shall, after notice of default or notice of prospective default to Unit Operator by the authorized officer and after failure of Unit Operator to remedy any actual default within a reasonable time (as determined by the authorized officer), result in automatic termination of this Agreement effective as of the date of the default, as determined by the authorized officer.

11.8

 Separate Plans of Operation may be submitted for separate productive zones, subject to the approval of the authorized officer. Also subject to the approval of the authorized officer, Plans of Operation shall be modified or supplemented when necessary to meet changes in conditions or to protect the interest of all parties to this Agreement.

ARTICLE XII - PARTICIPATING AREAS

12.1 

Prior to the commencement of production of Unitized Substances, the Unit Operator shall submit for approval by the authorized officer a schedule (or schedules) of all land then regarded as reasonably proved to be productive from a pool or deposit discovered or developed; all lands in said schedule (or schedules), on approval of the authorized officer, will constitute a Participating Area (or Areas) effective as of the date production commences or the effective date of this Unit Agreement, whichever is later. Said schedule (or schedules) shall also set forth the percentage of Unitized Substances to be allocated, as herein provided, to each tract in the Participating Area (or Areas) so established and shall govern the allocation of production commencing with the effective date of the Participating Area.

12.2 

A separate Participating Area shall be established for each separate pool or deposit of Unitized Substances or for any group thereof which is produced as a single pool or deposit and any two or more Participating Areas so established may be combined into one, on approval of the authorized officer. The effective date of any Participating Area established after the commencement of actual production of Unitized Substances shall be the first of the month in which is obtained the knowledge or information on which the establishment of said Participating Area is based, unless a more appropriate effective date is proposed by the Unit Operator and approved by the authorized officer.

12.3

 Any Participating Area (or Areas) established under 12.1 or 12.2 above shall, subject to the approval of the authorized officer, be revised from time to time to include additional land then regarded as reasonably proved to be productive from the pool or deposit for which the Participating Area was established or to include lands necessary to unit operations, or to exclude land then regarded as reasonably proved not to be productive from the pool or deposit for which the Participating Area was established or to exclude land not necessary to unit operations and the schedule (or schedules) of allocation percentages shall be revised accordingly.

12.4

 Subject to the limitation cited in 12.1 hereof, the effective date of any revision of a Participating Area established under Articles 12.1 or 12.2 shall be the first of the month in which is obtained the knowledge or information on which such revision is predicated, provided, however, that a more appropriate effective date may be used if justified by the Unit Operator and approved by the authorized officer.

12.5

No land shall be excluded from a Participating Area on account of depletion of the Unitized Substances, except that any Participating Area established under the provisions of this Article XII shall terminate automatically whenever all operations are abandoned in the pool or deposit for which the Participating Area was established.

12.6

 Nothing herein contained shall be construed as requiring any retroactive adjustment for production obtained prior to the effective date of the revision of a Participating Area.

ARTICLE XIII - ALLOCATION OF UNITIZED SUBSTANCES




13.1 

All Unitized Substances produced from a Participating Area, established under this Agreement, shall be deemed to be produced equally on an acreage basis from the several tracts of Unitized Land within the participating Area established for such production.

13.2

 For the purpose of determining any benefits accruing under this Agreement, each Tract of Unitized Land shall have allocated to it such percentage of said production as the number of acres in the Tract included in the Participating Area bears to the total number of acres of Unitized Land in said Participating Area.




13.3

Allocation of production hereunder for purposes other than for settlement of the royalty obligations of 

the respective Working Interest Owners, shall be on the basis prescribed in the

Unit Operating Agreement whether in conformity with the basis of allocation set forth above or otherwise.














Unit Agreement for the Development and Operation of the Blue Mountain Unit Area

County of Humboldt, State of Nevada




13.4 

The Unitized Substances produced from a Participating Area shall be allocated as

provided herein regardless of whether any wells are drilled on any particular part or tract of said Participating 

Area.

ARTICLE XLV - RELINQUISHMENT OF LEASES




14.1

 Pursuant to the provisions of the Federal leases and 43 CFR 3244.1, a lessee of record shall, subject to the provisions of the Unit Operating Agreement, have the right to relinquish any of its interests in leases committed hereto, in whole or in part; provided, that no relinquishment shall be made of interests in land within a Participating Area without the prior approval of the Director.




14.2

 A Working Interest Owner may exercise the right to surrender, when such right is vested in it by any non-Federal lease, sublease, or operating agreement, provided that each party who will or might acquire the Working Interest in such lease by such surrender or by forfeiture is bound by the terms of this Agreement, and further provided that no relinquishment shall be made

of such land within a Participating Area without the prior written consent of the non-Federal Lessor.

14.3

 If, as the result of relinquishment, surrender, or forfeiture the Working Interests become vested in the fee owner or lessor of the Unitized Substances, such owner may:




(a)
