APPROVAL OF STATE
ENGINEER

     This is to certify that
I have examined the foregoing application, and do hereby grant the same, subject
to the following limitations and conditions: This permit is issued subject to
existing rights. It is understood that the amount of water herein granted is
only a temporary allowance and that the final water right obtained under this
permit will be dependent upon the amount of water actually placed to beneficial
use. It is also understood that this right must allow for a reasonable lowering
of the static water level. This well shall be equipped with a two (2) inch
opening for measuring depth to water. If the well is flowing, a valve must be
installed and maintained to prevent waste. A totalizing meter must be installed
and maintained in the discharge pipeline near the point of diversion and
accurate measurements must be kept of wirer placed to beneficial use.The
totalizing meter must be installed before any use of water begins, or before the
Proof of Completion of Work is filed. This source is located within an area
designated by the State Engineer, pursuant to NRS 534.030. The State retains the
right to regulate the use of the water herein granted at any and all
times.
     This permit does not
extend the permitted the right of ingress and egress on public, private or
corporate lands.
     The
issuance of this permit does not waive the requirements that the permit holder
obtain other permits from State, Federal and local agencies.
     This permit is issued under the provisions
of NRS 534.120(2) as a preferred
use.
     This permit is issued
under the preferred use provisions of NRS Chapter 534. The manner of use of
water under this permit is by nature of its activity a temporary use and any
application to change the manner of use granted under this permit will be
subject to additional determination and evaluation with respect to the permanent
effects on existing rights and the resource within the ground water
basin.
     The total combined
duty of water under Permits 72978,73541, 73542 and 73543 shall not exceed 2,186
acre-feet per year.
     This
project is a renewable energy generation project as defined in NRS 701.080. An
annual report that documents the amount of water diverted and beneficially used
under. Permits 72978, 73541, 73542 and 73543 shall be filed not later than
January 31, of the year following the reporting year. A ground water monitoring
plan shall be submitted for approval by the State Engineer and shall be
implemented prior to development of water under these permits. The ground water
monitoring plan shall be sufficient to establish the magnitude and areal extent
of water level impacts that may result from pumpage under these permits. If
ground water monitoring data indicate an unreasonable effect upon prior water
rights to the extent those rights cannot be satisfied, diversion of water under
these permits may be curtailed or mitigation measures may be
required.

Item 12 Remarks

Nevada Geothermal Power, Inc. and its affiliates
(NGP) are developing a 30-megawatt geothermal power plant located 24 miles west
of Winnemucca in Humboldt County, Nevada. The plant will be situated in the
Desert Valley water basin (Basin 31) on the western slope of Blue Mountain and
will be water-cooled to enhance its production capability during critical peak
periods of electrical consumption. To optimize generation, the facilities will
include a cooling tower that will require approximately 1,400-1600 GPM (see
attached Power Engineers letter) of make-up water (evaporation in the cooling
process) and blown-down water (replacement for saturation). The following
summarizes the process and benefits of the water that will be consumed in the
electrical generation process.

NGP has acquired several geothermal leases on private
and federal lands to provide the geothermal resource necessary to power the
plant. In each lease, NGP has reserved the rights to use the surface of the
leased lands as required for project development. The intended point of
diversion for plant cooling water is currently located on a private lease with
Nevada Land and Resource Company (NLRC), NLRC lease terms require NGP to file
jointly with them for water rights, but reserve to NGP the right to use the
water in its generation process.

While the location of the plant is relatively remote,
it is easily accessed via existing roads. The footprint of the plant is small
and additional impact to the area will be limited. The project will add 10 to 15
permanent full-time jobs to the local economy while increasing the county
property tax base and providing
an additional opportunity for increased Net Proceeds Tax revenues to the state
and county.

The total required for the cooling tower may be
pumped from one well, or may be taken from two or more of the four wells
planned. The area has wells with varied productivity and so production may be
split between them or taken from one well.

Item 12 Remarks

Nevada Geothermal Power, Inc. and its affiliates
(NGP) are developing a 30-megawatt geothermal power plant located 24 miles west
of Winnemucca in Humboldt County, Nevada. The plant will be situated in the
Desert Valley water basin (Basin 31) on the western slope of Blue Mountain and
will be water-cooled to enhance its production capability during critical peak
periods of electrical consumption. To optimize generation, the facilities will
include a cooling tower that will require approximately 1,400-1600 GPM (see
attached Power Engineers letter) of make-up water (evaporation in the cooling
process) and blown-down water (replacement for saturation). The following
summarizes the process and benefits of the water that will be consumed in the
electrical generation process.

NGP has acquired several geothermal leases on private
and federal lands to provide the geothermal resource necessary to power the
plant. In each lease, NGP has reserved the rights to use the surface of the
leased lands as required for project development. The intended point of
diversion for plant cooling water is currently located on a private lease with
Nevada Land and Resource Company (NLRC). NLRC lease terms require NGP to file
jointly with them for water rights, but reserve to NGP the right to
use the water in its generation
process.

While the location of the plant is relatively remote,
it is easily accessed via existing roads. The footprint of the plant is small
and additional impact to the area will be limited. The project will add 10 to 15
permanent full-time jobs to the local economy while increasing the county
property tax base and providing an additional opportunity for increased Net
Proceeds Tax revenues to the state and county.

The total required for the cooling tower may be
pumped from one well, or may be taken from two or more of the four wells
planned. The area has wells with varied productivity and so production may be
split between them or taken from one well.

only a temporary allowance and that the final water right obtained under this
permit will be dependent upon the amount of water actually placed to beneficial
use. It is also understood that this right must allow for a reasonable lowering
of the static water level. This well shall be equipped with a two (2) inch
opening for measuring depth to water. If the well is flowing, a valve must be
installed and maintained to prevent waste. A totalizing meter must be installed
