Lessor, for and in consideration of the sum of $10.00 and other good and valuable consideration and of the rentals and royalties herein provided and of the covenants and agreements hereinafter contained, hereby grants, demises, leases and lets unto Lessee the Rights with the sole and exclusive right to Lessee to drill for, produce, extract, take and remove from the Lands: (1) all products of geothermal processes, embracing indigenous steam, hot water and hot brines; (2) steam and other gases, hot water and hot brines resulting from water, gas, or other fluids artificially introduced into subsurface formations; (3) heat or other associated energy found beneath the surface of the earth; (4) geothermal water from geopressured zones; and (5) by products of any of the foregoing such as solution minerals (exclusive of oil or hydrocarbon gas that can be separately produced) which are found in solution or in association with or derived from any of the foregoing (each collectively referred to as "Substances"). For the same consideration, Lessee is hereby granted the right to store, utilize, process, convert, and otherwise use such Substances on or off the Lands and to sell the same or any part thereof on or off the Lands during the term hereof, with the right of entry to the extent that right of entry belongs to Lessor thereon at all times for said purposes, and Lessee shall obtain from the surface landowner the right to construct, use, maintain, erect, repair and replace thereon, and to remove therefrom all roads, pipelines, ditches and lanes, telephone and telegraph lines, utility installations power lines, poles tanks, evaporation or settling basins, extraction or processing plants, machinery, equipment, buildings, electric power plants and equipment for generation and transmission of electric power, and for the handling, treatment or storage of the Substances, and all structures and facilities relating thereto, which Lessee may desire to erect, construct, or install in carrying on Lessee's business and operations on or from the Lands; and Lessee shall obtain from the surface landowner the right to erect, maintain, operate and remove a plant or plants, structures and facilities with all necessary appurtenances for the conversion of the Substances into heat, power or another form of energy, and for the extraction of products from steam, brine or water produced from the Lands, including all rights necessary or convenient thereto, together with rights of way for passage over, upon and across and ingress and egress to and from the Lands for any or all of the above mentioned purposes. Lessee shall also have the right to utilize or to dispose of waste brine and other waste products from a well or wells on the Lands into a well or wells drilled or converted for that purpose on the Lands, and the right to inject water, brine, steam and gases from a well or wells on the Lands for the purpose of maintaining or restoring pressure, increasing or maintaining production, or testing in the productive zones beneath the Lands. Lessee acknowledges that Lessor does not own the surface water rights with respect to the Lands, therefore Lessor's activities, to the extent that they affect surface water rights, shall be subject to agreements to be entered into with the holders of such rights.

(c)

Lessee shall be entitled, without accounting to Lessor therefor in any manner, to flow and/or blow wells without restriction for testing or operating purposes.



2. LEASE TERMS AND RENTALS



(a)

The Lease shall be for a term of ten (10) years from and after the date hereof ("Primary Term") and for so long thereafter as (i) any of the Substances shall be produced in Commercial Quantities from any of the Lands or (ii) for so long as the Lease may be kept in force under any other provision hereof. For the purposes of the Lease, the term "Commercial Quantities" shall mean the production and sale of Substances derived from the Lands to parties dealing at arm's length in amounts sufficient to maintain a profitable level of operations.

(b)

If at the expiration of the Primary Term hereof none of the Substances is being produced in Commercial Quantities, but on or before that date reworking operations (including, among other things, cleaning, testing, repair, and replacement of wells and related facilities and equipment necessary to cause production from such wells), or the actual drilling in search of any of the Substances are commenced on the Lands, the Lease will continue in force for so long as such operations are continuously prosecuted and Lessee shall be obligated to continue the rental payments at the rate in effect for the tenth (10th) year of the lease, and such operations shall be considered to be continuously prosecuted if not more than six (6) months shall elapse between completion or abandonment of one well and beginning of the actual drilling or reworking of another well. If, as a result of such operations, any of the Substances are produced in Commercial Quantities or production is restored, the Lease will remain in force for so long as any of the Substances shall be so produced in Commercial Quantities. If said Substances are being so produced in Commercial Quantities from any part of the Lands at or after expiration of the Primary Term hereof and all of such production shall thereafter cease, Lessee may, within six (6) months from cessation of such production, resume drilling or reworking operations in an effort to obtain or restore such production of any of the Substances, in which event the Lease shall remain in force for so long as such operations are continuously prosecuted, as provided above; and, if such operations shall result in production in Commercial Quantities of any of the Substances, for so long as any of them are produced in Commercial Quantities.

(d)

Allocation, as aforesaid, shall cease upon any termination, either in whole or in part (by surrender, forfeiture or otherwise), of this or any other lease covering lands in such Unit as to the lands covered by such terminated lease or part thereof. In the event of the failure of Lessor's or any other owner's title as to any portion of the lands included in any such Unit, such portion of such land shall likewise be excluded in allocating production from such Unit; provided, however, Lessee shall not be held to account for any production allocated to any lands to be excluded, as aforesaid, from such Unit unless and until Lessee has actual knowledge of the aforesaid circumstances requiring such exclusion,

14. SURRENDER

(a)

Lessee may, at any time, surrender the Lease to Lessor in its entirety or, from time to time, surrender only so much of the Lands as Lessee may elect in the instrument of surrender by executing and delivering to the Lessor and recording in the Official Records of Humboldt County, Nevada in which the Lands are located a quitclaim deed or deeds covering all or any part of the Lands so selected by Lessee for surrender, and Lessee shall thereby be relieved of all obligations as to the acreage so surrendered, except for obligations for rental payments provided for under Section 2(c) which shall not be affected, and obligations already accrued by the terms hereof or as provided by Section 15 and 16 hereof.

If Lessee shall be in default in the performance of any obligations under the Lease other than the payment of rental or royalty, and if for a period of thirty (30) days after written notice is given to Lessee by Lessor of such default and Lessee shall fail to commence and thereafter diligently and in good faith prosecute action to remedy such default, Lessor may terminate the Lease. No default in the performance of any condition or obligation hereof or termination by reason thereof shall affect the Rights of Lessee hereunder with respect to any drilling, injection, disposal, or producing well or wells and related facilities and rights of access thereto, in regard to which Lessee is not in default, together with an area of acreage reasonably necessary for operation and maintenance thereof in the form of a square surrounding each such well then completed or being drilled, and rights of way, easements, and surface areas necessary for continuing Lessee's operations on the Lands retained, or on other lands in the vicinity thereof, including without limitation sites for electric generating plants or for other processing or use of Substances.
