agrees to make Advances to Borrower from time to time during the Availability
Period in an aggregate principal amount up to, but not in excess of an aggregate
of $20,000,000 (the "Loans"). The Loans may from time to time be Base
Rate Loans or LIBOR Loans as determined by the Borrower in the applicable
Borrowing Request and notified to the Lender in accordance with Section 2.4
below.

     2.2 Promissory Note for
Loans. The Loans made by the Lender shall be evidenced by,
and shall be due and payable in accordance with the terms of, a promissory note
executed by Borrower in favor of the Lender in an amount equal to the aggregate
amount of Loans committed to under Section 2.1, substantially in the form of
Exhibit A attached hereto (the "Note"). The Initial Advance shall be evidenced

requirement of at least US$23,000,000 described in clause (xxviii) under
"Conditions Precedent" in the commitment letter described in clause (i) of the
definition of Construction Financing Documents.

and upon the terms and conditions set forth in this Agreement and upon
satisfaction of the conditions precedent set forth in Sections 3.1 and 3.2
hereto, as applicable:




18

     (a) The Lender shall make
Advances to Borrower of the proceeds of the Loans as follows: (i) the Initial
Advance, in accordance with Section 2.4(b), and (ii) subsequent Advances, in
accordance with the procedures set forth in Section 2.4(c) .

     (b) The Initial Advance for a
minimum of $5,000,000 up to the aggregate amount of the Loans shall be made on
the Effective Date and shall be disbursed by the Lender in Dollars in
immediately available funds to the Borrower Account (such date of disbursement,
the "Initial Disbursement Date") subject to the receipt by the Lender at
least three (3) Business Days prior to the Effective Date of a written notice in
the form of Exhibit B-I attached hereto (the "Initial Request").

     (c) With respect to each Advance
of the Loans (other than the Initial Advance) requested in accordance with the
Development Loan Budget, Lender shall receive written notice in the form of
Exhibit B-2 attached hereto (a "Subsequent Advance
Request") from Borrower by 10:00 a.m. New York City time at least five
(5) Business Days prior to the date of such Advance. Each Subsequent Advance
Request shall specify the aggregate amount of the Advances requested from
Lender, such amount to be for a minimum of five million dollars ($5,000,000) or,
if less, the remaining amount of undrawn Loans. The Borrower shall only be
entitled to submit two (2) Subsequent Advance Requests (other than the Initial
Request) during the Availability Period. Provided that Borrower has complied
with the conditions set forth in Section 3.2, not later than 12:00 noon, New
York City time, on the fifth (5th) Business Day after the delivery of the
Subsequent Advance Request, the Lender shall disburse the requested Advance in
Dollars in immediately available funds to the Borrower Account (such date of
disbursement, the "Subsequent Disbursement Date").

     2.5 Interest.

     (a) From the Initial Disbursement
Date or relevant Subsequent Disbursement Dates until paid in full, as long as no
Event of Default has occurred and is continuing, the outstanding principal
balance of the Loans shall bear interest at a rate equal to the Interest Rate,
compounded annually. From the date hereof until paid in full, as long as no
Event of Default has occurred and is continuing, the Deferred Commitment Fees,
if any, shall accrue interest at a rate equal to the Interest Rate, compounded
annually.

     (b) Interest and fees under this
Agreement shall be calculated on the basis of the actual number of days
(including the first day but excluding the last day) elapsed during the period
for which such interest or fee is payable over a year




19

comprised of 360 days (or in the case of a Base Rate Loan
calculated at other than the Federal Funds Effective Rate, 365 days or, if
appropriate 366 days).

     (c) Upon the occurrence and
during the continuance of any Event of Default, and upon notice to the Borrower,
the outstanding principal balance of the Loans and the Deferred Commitment Fees,
if any, shall bear interest at a rate equal to the Default Rate, compounded
annually.

     (d) It is the intention of the
Parties to conform strictly to applicable usury laws and anything herein or
elsewhere to the contrary notwithstanding, the Obligations shall be subject to
the limitation that Borrower shall not be required to pay, and Lender shall not
be entitled to charge or receive, any interest to the extent that such interest
exceeds the maximum rate of interest which Lender is permitted by applicable Law
to contract for, charge or receive and which would not give rise to any claim or
defense of usury. If, as a result of any circumstances whatsoever, performance
of any provision hereof shall, at the time performance of such provision is due,
violate applicable usury law, then, ipso facto, the Obligation to be
performed shall be reduced to the highest lawful rate, and if, from any such
circumstance, Lender shall ever receive interest or anything which might be
deemed interest under applicable Law which would exceed the highest lawful rate,
the amount of such excess interest shall be applied to the reduction of the
principal amount owing on account of the Note or the amounts owing on other
Obligations and not to the payment of interest, or if such excessive interest
exceeds the unpaid principal balance of the Obligations, such excess shall be
refunded to Borrower.

     (e) By delivering a
Continuation/Conversion Notice in the form attached hereto as Exhibit B-3 to the
Lender on or before 12:00 noon on a Business Day, the Borrower may from time to
time irrevocably elect, on not less than three (3) Business Days' notice that
all, or any portion in an aggregate minimum amount of $5,000,000 and an integral
multiple of $1,000,000, be, in the case of Base Rate Loans, converted into LIBOR
Loans or be, in the case of LIBOR Loans, converted into Base Rate Loans or
continued as LIBOR Loans (in the absence of the delivery of a
Continuation/Conversion Notice with respect to any LIBOR Loan at least three
Business Days before the last day of the then current Interest Period with
respect thereto, such LIBOR Loan shall, on such last day, automatically convert
to a Base Rate Loan); provided, however, that, at the election of Lender,
no portion of the outstanding principal amount of any Loans may be continued as,
or be converted into, LIBOR Loans when any Default has occurred and is
continuing.

     (f) The Lender may, if it so
elects, fulfill its obligation to make, continue or convert LIBOR Loans
hereunder by causing one of its foreign branches or Affiliates (or an
international banking facility created by the Lender) to make or




20

maintain such LIBOR Loan; provided, however, that such
LIBOR Loan shall nonetheless be deemed to have been made and to be held by the
Lender, and the obligation of the Borrower to repay such LIBOR Loan shall
nevertheless be to the Lender for the account of such foreign branch, Affiliate
or international banking facility. In addition, the Borrower hereby consents and
agrees that, for purposes of any determination to be made for purposes of this
Agreement, it shall be conclusively assumed that the Lender elected to fund all
LIBOR Loans by purchasing Dollar deposits in its LIBOR Office's interbank
eurodollar market.

     2.6 Repayment.
Notwithstanding anything herein to the contrary, Borrower shall have no
obligation to make any payment of principal or interest on the Loans, or in
respect of any Obligation (other than indemnity obligations pursuant to Sections
5.1(c) and 7.12 of this Agreement), prior to the Maturity Date.

     (b) On the Maturity Date, the

and without any premium, penalty or other additional charge, at any time.

     2.9 Certain LIBOR and Interest
Provisions.

     (a) LIBOR Lending Unlawful.
If the Lender shall determine (which determination shall, upon notice
thereof to the Borrower, be conclusive and binding on the Borrower) that the
introduction of or any change in or in the interpretation of any law makes it
unlawful, or any Governmental Authority asserts that it is unlawful, for the
Lender to make or continue any Loan as, or to convert any Loan into, a LIBOR
Loan, the obligations of the Lender to make, continue or convert any such LIBOR
Loan shall, after the determination thereof, forthwith be suspended until the
Lender shall notify the Borrower that the circumstances causing such suspension
no longer exist, and all outstanding LIBOR Loans payable to the Lender shall
automatically convert into Base Rate Loans at the end of the then current
Interest Periods with respect thereto or sooner, if required by such law or
assertion.

its relevant market; or

     (ii) by reason of circumstances
affecting its relevant market, adequate means do not exist for ascertaining the
interest rate applicable hereunder to LIBOR Loans for such Interest Period;

  obligations of the Lender to make or continue any Loans under Section 2.1 and
  Section 2.4 on the last day of the Interest Period applicable thereto as, or
  to convert any Loans into, LIBOR Loans shall forthwith be suspended until the
  Lender shall notify the Borrower that the circumstances causing such suspension
  no longer exist.

     (c) Increased LIBOR Loan Costs
  etc.

     (i) The Borrower agrees to
reimburse the Lender for any increase in the cost to the Lender, or any
reduction in the amount of any sum receivable by the Lender in respect of, the
Lender's commitments and the making of Loans hereunder (including the making,
continuing or maintaining (or of its obligation to make or continue) any Loans
as, or of converting (or of its obligation to convert) any Loans into, LIBOR
Loans) that arise in connection with any change in, or the introduction,
adoption, effectiveness, interpretation, reinterpretation or phase in after the
Closing Date of; any law or regulation, directive, guideline, decision or
request (whether or not having the force of law) of any Governmental Authority
(each, a "Change in Law"), that (a) imposes, modifies or deems applicable
any reserves, special deposit or similar requirement against assets of, deposits
with or for the account of, or credit extended by the Lender, or (b) imposes on
the Lender or the London interbank market any other condition affecting this
Agreement or LIBOR Loans made by the Lender or participation therein, except for
(i) such changes with respect to increased capital costs and Taxes which are
governed by Sections 2.9(e) and 2.9(f), respectively, and (ii) increased costs
which are already included in the determination of the Statutory Reserve Rate.
The Lender shall promptly notify the Borrower in writing of the occurrence of
any such event, stating the reasons therefor and the additional amount required
to fully compensate the Lender for such increased cost or reduced amount. Such
additional amounts shall be payable by the Borrower directly to the Lender
within 10 days of its receipt of such notice, and such notice shall, in the
absence of manifest error, be conclusive and binding on the Borrower.

     (ii) A certificate of an officer
of the Lender setting forth the amount or amounts necessary to compensate the
Lender as specified in this Section 2.9(c) shall be delivered to the Borrower
and shall be conclusive absent manifest error.




23

The Borrower shall pay the Lender the amount shown as due on
any such certificate within 5 days after receipt thereof.

     (iii) Promptly after the Lender
has determined that it will make a request for increased compensation pursuant
to this Section 2.9(c), the Lender shall notify the Borrower thereof Failure or
delay on the part of the Lender to demand compensation pursuant to this Section
shall not constitute a waiver of the Lender's right to demand such
compensation.

     (d) Funding Losses.
In the event the Lender shall incur any loss or expense (including any loss
or expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired by the Lender to make or continue any portion of the
principal amount of any Loan as, or to convert any portion of the principal
amount of any Loan into, a LIBOR Loan) as a result of:

     (i) any conversion or repayment
or prepayment of the principal amount of any LIBOR Loan on a date other than the
scheduled last day of the Interest Period applicable thereto;

     (ii) any Loans not being made as
LIBOR Loans in accordance with the Borrowing Request therefor;

     (iii) any Loans not being
continued as, or converted into, LIBOR Loans in accordance with the
Continuation/Conversion Notice therefor; or

     (iv) any LIBOR Loans not being
prepaid in accordance with any notice delivered pursuant to Section 2.7;

then, upon the written notice of the Lender to the Borrower,
the Borrower shall, within 10 days of its receipt thereof, pay directly to the
Lender such amount as will (in the reasonable determination of the Lender)
reimburse the Lender for such loss or expense. Such written notice shall, in the
absence of manifest error, be conclusive and binding on the Borrower. In the
case of a LIBOR Loan, such loss, cost or expense to the Lender shall be deemed
to be the amount determined by the Lender to be the excess, if any, of (i) the
amount of interest which would have accrued on the principal amount of such Loan
had such event not occurred, as the Adjusted LIBOR that would have been
applicable to such Loan, for the period from the date of such event to the last
day of the then current Interest Period therefor (or, in the case of a failure
to borrow, convert or continue a LIBOR Loan, for the period that would have been
the Interest Period for such Loan), over (ii) the amount of interest which would
accrue on such principal




24

amount for such period at the interest rate which the Lender
  would bid were it to bid, at the commencement of such period, for deposits in
  dollars of a comparable amount and period from other banks in the Eurodollar
  market. Such written notice shall, in the absence of manifest error, be conclusive
  and binding on the Borrower.

     (e) Increased Capital
Costs. If, after the Effective Date, any Change in Law affects or
would affect the amount of capital required or expected to be maintained by the
Lender or any Person controlling the Lender, and the Lender determines (in good
faith but in its sole and absolute discretion) that the rate of return on its or
its controlling Person's capital as a consequence of the commitment or the Loans
made, by the Lender is reduced to a level below that which the Lender or
controlling Person could have achieved but for the occurrence of any such
circumstance, then upon notice from time to time by the Lender to the Borrower,
the Borrower shall within five days following receipt of such notice pay
directly to the Lender additional amounts sufficient to compensate the Lender or
controlling Person for such reduction in rate of return. A statement of the
Lender as to any such additional amount or amounts shall, in the absence of
manifest error, be conclusive and binding on the Borrower. In determining such
amount, the Lender may use any reasonable method of averaging and attribution
that it (in its sole and absolute discretion) shall deem applicable.

     A certificate of an officer of
the Lender setting forth the amount or amounts necessary to compensate the
Lender as specified in this Section 2.9(e) shall be delivered to the Borrower
and shall be conclusive absent manifest error.

     Promptly after the Lender has
determined that it will make a request for increased compensation pursuant to
this Section 2.9(e), the Lender shall notify the Borrower thereof. Failure or
delay on the part of the Lender to demand compensation pursuant to this Section
2.9(e) shall not constitute a waiver of the Lender's right to demand such
compensation.

     (f) Taxes. The Borrower
covenants and agrees as follows with respect to Taxes.

     (i) Any and all payments by the
Borrower under each Loan Document shall be made free and clear of, and without
deduction or withholding for or on account of, any Taxes, except to the extent
such deduction or withholding is required by Law. In the event that any Taxes
are required by Law to be deducted or withheld from any payment required to be
made by or on behalf of the Borrower to the Lender under any Loan Document,
then:




25

     (1) if such Taxes are Non-Excluded Taxes, the amount payable by the
Borrower shall be increased as may be necessary such that the net payment, after
withholding or deduction for or on account of such Non-Excluded Taxes, is equal
to the amount provided for in such Loan Document (and for the avoidance of
doubt, it shall be the sole responsibility of the Borrower to pay such increased
amounts without regard to whether such Taxes are imposed on the Borrower or
another party); and

     (2) the Borrower shall withhold
or cause to be withheld the full amount of such Taxes from such payment (as
increased pursuant to clause (i)(1), if applicable) and shall pay or cause to be
paid such amount to the Governmental Authority imposing such Taxes in accordance
with applicable law.

     (ii) Without duplication, the
Borrower shall pay any and all Other Taxes that arise from the transactions
contemplated by any of the Loan Documents to the relevant Governmental Authority
imposing such Other Taxes in accordance with applicable Law.

     (iii) As promptly as practicable
after the payment of any Taxes or Other Taxes, and in any event within 45 days
of any such payment, the Borrower shall furnish to the Lender a copy of an
official receipt (or a certified copy thereof) or other documentation reasonably
satisfactory to the Lender evidencing the payment of such Taxes or Other
Taxes.

     (iv) The Borrower shall indemnify
the Lender for any Non-Excluded Taxes and Other Taxes levied, imposed, assessed
on or actually paid by or on behalf of the Lender. With respect to
indemnification for Non-Excluded Taxes and Other Taxes actually paid by the
Lender or the indemnification provided in the immediately preceding sentence,
such indemnification shall be made within 45 days after the date the Lender
makes written demand therefor. A certificate stating the amount of such
liability and setting forth in reasonable detail the calculation thereof
delivered to the Borrower by the Lender shall be conclusive absent manifest
error.

     (v) The Lender shall deliver
documentation prescribed by applicable Law as will enable the Borrower to
determine whether or not and to what extent the Lender is subject to
withholding, backup withholding or information reporting requirements. Without
limiting the generality of the foregoing, the Lender shall deliver to the
Borrower, on or before it becomes a party to this Agreement and upon expiration
of a previously delivered form, two duly completed original copies of (i) if
such Lender is a "United States person" within the meaning of Section
7701(a)(30) of the Code, Internal Revenue Service Form W-9 or (ii) if such
Lender is not a "United States person" within the meaning of Section 7701(a)(30)
of the Code, Internal Revenue Service Form W-8BEN (properly establishing a
complete exemption from or reduction in the United States withholding tax with
respect




26

to payments to be received under this Agreement or the Loans)
or W-8ECI. The Lender shall promptly notify the Borrower at any time it is no
longer qualified for the reduction or exemption from the United States
withholding tax as claimed in any previously delivered form.

     (g) Payments, Computations,

made by the Borrower to the Lender without setoff, deduction or counterclaim not
later than 1:00 p.m. New York City time on the date due in same day or
immediately available funds to such account as the Lender shall specify from
time to time by notice to the Borrower. Funds received after that time shall be
deemed, in the Lender's sole discretion, to have been received by the Lender on
the next succeeding Business Day. Except as otherwise set forth herein, payments
due on a day other than a Business Day shall be made on the preceding Business
Day.

     (h) Setoff. The Lender
shall, upon the occurrence and during the continuance of any Event of Default,
have the right to appropriate and apply to the payment of the Obligations owing
to it (whether or not then due), and (as security for such Obligations) the
Borrower hereby grants to the Lender a continuing security interest in, any and
all balances, credits, deposits, accounts, or moneys of the Borrower then or
thereafter maintained with the Lender; the Lender agrees promptly to notify the
Borrower after any such setoff and application made by the Lender; provided,
however, that the failure to give such notice shall not affect the validity
of such setoff and application. The rights of the Lender under this Section are
in addition to other rights and remedies (including other rights of setoff under
applicable law or otherwise) which the Lender may have.

Section 7.7 shall preclude the Lender from bringing any legal suit, action or
proceeding against Borrower in the courts of any jurisdiction where Borrower or
any of its property or assets may be found or located. To the extent permitted
by the Laws of any such jurisdiction, Borrower hereby irrevocably submits to the
jurisdiction of any such court and expressly waives, in respect of any such
suit, action or proceeding, the jurisdiction of any court or courts which now or
hereafter, by reason of its present or future domiciles, or otherwise, may be
available to it.

     (i) Borrower hereby irrevocably
waives any objection which it may now or hereafter have to the laying of venue
of any of the aforesaid actions or proceedings arising out of or in connection
with any Loan Document or the transactions in connection with, or relating
hereto or thereto, brought in the courts referred to in clause (d) above and
hereby further irrevocably waives and agrees not to plead or claim in any such
court that any such action or proceeding brought in any such court has been
brought in an inconvenient forum.

     7.8 Notices. Without
modifying any of the provisions of this Agreement concerning the requirements
for, or waiver of, any notice, all notices, consents, or other
communications required or permitted to be given pursuant to this Agreement
shall be in writing and shall be considered properly given if mailed by first
class United States mail,




58

postage prepaid, registered or certified with return receipt
requested, facsimile, by delivering same in person or by a nationally recognized
overnight courier service to the intended addressee. Notice so mailed shall be
effective three (3) days after it is deposited in a receptacle maintained by the
United States Postal Office for the acceptance of mail. Notice given in any
other manner shall be effective only if and when received by the addressee. For
purposes of notice, the addresses of the Parties shall be as set forth on
Schedule 7.8 to this Agreement; provided, however, that any Party shall have the
right to change its address for notice hereunder to any other location within
the continental United States by the giving of ten (10) days' notice to the
other Parties in the manner set forth hereinabove.

     7.9 Counterparts. To
facilitate execution, this Agreement may be executed in as many counterparts as
may be required; and it shall not be necessary that the signature of, or on
behalf of, each party, or that the signatures of all persons required to bind
any party, appear on such counterpart, but it shall be sufficient that the
signature of, or on behalf of, each party, or that the signature of the persons
required to bind any party, appear on one or more of the counterparts. All
counterparts shall collectively constitute a single agreement. It shall not be
necessary in making proof of this Agreement to produce or account for more than
a number of counterparts containing the respective signatures of, or on behalf
of, all of the Parties hereto.

     7.10 Confidentiality. The
Lender agrees to hold any information designated as "confidential" that it
receives from Borrower pursuant to this Agreement in confidence in accordance
with procedures adopted by Lender in good faith to protect confidential
information of third parties delivered to it, except for disclosure (a) to the
Lender's directors, owners, officers, employees, agents, legal counsel,
accountants and other professional consultants, provided that such Persons are
bound by the provisions of this Section 7.10, have a professional obligation to
maintain the confidentiality of confidential information supplied to them or
agree to maintain the confidentiality thereof on substantially the same basis as
is provided under this Section 7.10, (b) to other professional advisors for the
Lender, provided that such other professional advisor agrees to maintain the
confidentiality thereof on substantially the same basis as is provided under
this Section 7.10, (c) to any Governmental Authority having jurisdiction over
the Lender as required by such Governmental Authority pursuant to any applicable
Law, (d) as required by applicable Law or legal process or in connection with
any legal proceeding to which the Lender is a party, (e) to another Person in
connection with a participation or assignment or a proposed participation or
assignment as contemplated by Section 7.1 (which Person shall be required to
sign a confidentiality agreement provided by the Lender with respect to such
confidential information), (f) to any Affiliate of the Lender provided that such
Affiliate shall be subject to the same obligations of confidentiality under this
Section 7.10 as the Lender, (g) to prospective purchasers of any Collateral in
connection with any disposition thereof, and (h) to any other Lender. The
confidentiality




59

obligations set forth above shall not, however, apply to any
information (i) which is not treated by Borrower in a manner designed to
maintain the confidentiality thereof; (ii) filed with any Governmental Authority
and available to the public, (iii) published in any public medium from a source
other than, directly or indirectly, the Lender, or (iv) disclosed by Borrower to
any Person not associated with Borrower without first obtaining a
confidentiality agreement substantially similar to this Section 7.10. Nothing in
this Section 7.10 shall be construed to create or give rise to any fiduciary
duty on the part of the Lender to Borrower.

      7.11 Indemnity. Borrower
shall pay, indemnify, defend and hold the Indemnified Parties harmless from and
against any and all losses, claims, demands, suits, actions, investigations,
proceedings, and damages, and all reasonable attorneys' fees and disbursements
and other costs and expenses actually incurred in connection therewith (as and
when they are incurred and irrespective of whether suit is brought), which are
asserted against, imposed upon or incurred by any of them (a) in connection with
or as a result of or related to the Project or the execution, delivery,
enforcement, performance, or administration of this Agreement or the
transactions contemplated hereby or thereby, and (b) with respect to any
investigation, litigation, or proceeding related to the Project or this
Agreement or any Loan Document (irrespective of whether any Indemnified Party is
a party thereto), or any act, omission, event, or circumstance in any manner
related thereto (all the foregoing, collectively, the "Indemnified
Liabilities"). The foregoing to the contrary notwithstanding, Borrower shall
have no obligation to any Indemnified Party under this paragraph with respect to
any Indemnified Liability that a court of competent jurisdiction finally
determines to have resulted from the gross negligence or willful misconduct of
such Indemnified Party. If any Indemnified Party makes any payment to any other
Indemnified Party with respect to an Indemnified Liability as to which Borrower
was required to indemnify the Indemnified Party receiving such payment, the
Indemnified Party making such payment is entitled to be indemnified and
reimbursed by Borrower with respect thereto. Lender may notify Borrower of the
progress of any claims with respect to Indemnified Liabilities pursuant to this
Section 7.11 and Borrower shall be entitled, at its own cost and expense, to
participate in the defense of any third party claim for which it may owe the
Lender an indemnity, pursuant to this Section 7.11, it being understood that the
Lender shall control such defense. The obligations of Borrower in this Section
7.11 shall survive the termination of this Agreement and the discharge of
Borrower's other obligations under this Agreement. The provisions of this
Section 7.11 shall not he applicable to claims made by third parties in the
event Lender acquires an equity interest in Borrower.

      7.12 Scope of Liability.
Notwithstanding any other provision of the Loan Documents (except to the extent
of the Owner's interest in the Collateral pledged under the Pledge Agreement),
there shall be no recourse against Owner, Nevada Geothermal Power Company, Blue
Mountain Power Company, Inc., Nevada Geothermal




60

Power Inc. or their Affiliates (except Borrower), or the
stockholders or other owners, officers, directors or employees of any of them
(each, a "Non-Recourse Party"), for any liability to Lender arising in
connection with any breach or default under this Agreement except to the extent
the same is enforced against Borrower and the Collateral and the rents, issues,
profits, proceeds and products of the Collateral, and Lender shall look solely
to Borrower (but not to any Non-Recourse Party or to any distributions received
by any Non-Recourse Party in accordance with the terms of this Agreement) and
the Collateral and the rents, issues, profits, proceeds and products of the
Collateral in enforcing rights and Obligations under and in connection with the
Loan Documents; provided that (a) the foregoing provisions of this
Section 7.12 shall not constitute a waiver, release or discharge of any of the
indebtedness, or of any of the terms, covenants, conditions, or provisions of
this Agreement, the Note, or any other Loan Document (but without
personal liability to the Non-Recourse Parties), and the same shall continue
until this Agreement has terminated and all Obligations have been fully paid,
discharged, observed, or performed; and (b) the foregoing provisions of this
Section 7.12 shall not limit or restrict the right of Lender to name Borrower,
Owner or any other Non-Recourse Party as a defendant in any action or
suit for a judicial foreclosure or for the exercise of any other remedy under or
with respect to this Agreement or any other Loan Document, or otherwise, or for
injunction or specific performance, so long as no judgment in the nature of a
deficiency judgment shall be enforced against any Non-Recourse Party out of any
property, assets or funds other than the Collateral and the rents, issues,
profits, proceeds or products of the Collateral, and any other property of
Borrower.

as the Lender may reasonably request for the purposes of obtaining or preserving
the full benefits of this Agreement and of the rights and powers herein granted,
including, without limitation, filing any financing or continuation statements
under the Code (or other similar laws) in effect in any jurisdiction with
respect to the security interests created hereby.

-4-




          (iii)
If any amount payable under or in connection with any of the Collateral shall be

notice to the Lender.

     (h) Notices. The Pledgor
will advise the Lender promptly, in reasonable detail, of the occurrence of any
other event which could reasonably be expected to have a Material Adverse Effect
on the aggregate value of the Collateral or on the security interests created
hereby.

     (i) Pledged Interests.

same forthwith to the Lender in the exact form received, duly indorsed by such
Pledgor to the Lender, if required, together with an undated stock or equivalent
power covering such certificate duly executed in blank by the Pledgor and with,
if the Lender so requests, signature guaranteed, to be held by the Lender,
subject to the terms hereof, as additional collateral security for the
Obligations. Any sums paid upon or in respect of the Pledged Interests upon the
liquidation or dissolution of the Borrower shall be paid over to the Lender to
be held by it hereunder as additional collateral security for the Obligations,
and in case any distribution of capital shall be made on or in respect of the
Pledged Interests or any property shall be distributed upon or with respect to
the Pledged Interests pursuant to the recapitalization or reclassification of
the capital of the Borrower or pursuant to the reorganization thereof, the
property so distributed shall be delivered to the Lender to be held by it
hereunder as additional collateral security for the Obligations. If any sums of
money or property so paid or distributed in respect of the Pledged Interests
pursuant to the recapitalization or reclassification of the capital of the
Borrower or pursuant to the reorganization thereof shall be received by the
Pledgor, the Pledgor shall, until such money or property is paid or delivered to
the Lender, hold such money or property in trust for the Lender, segregated from
other funds of the Pledgor, as additional collateral security for the
Obligations.

          (ii)
Without the prior written consent of the Lender, the Pledgor shall not (1) vote
to enable, or take any other action to permit, the Borrower to distribute any
membership interests or other equity securities of any nature or to issue any
other securities convertible into or granting the right to purchase or exchange
for any membership interest or other equity securities of any nature of the
Borrower (2) sell, assign, transfer, exchange, or otherwise dispose of, or grant
any option with respect to, the Collateral, (3) create, incur or permit to exist
any Lien or option in favor of, or any claim of any Person with respect to, any
of the

-5-




Collateral, or any interest therein, except for the security
interests created by this Agreement or (4) enter into any agreement or
undertaking restricting the right or ability of the Pledgor or the Lender to
sell, assign or transfer any of the Collateral.

SECTION 5. VOTING RIGHTS. Unless an Event of Default shall have
occurred and be continuing and the Lender shall have given notice to the Pledgor
of its intent to exercise its corresponding rights pursuant to Section 6 below,
the Pledgor shall be permitted to exercise all voting and other rights with
respect to the Pledged Interests; provided, however, that no vote shall
be cast or other right exercised or other organizational action taken which, in
the Lender's judgment, would impair the Collateral or which would be
inconsistent with or result in any violation of any provision of the Loan
Agreement, the Note, this Agreement or any other Loan Document or Security
Document.

SECTION 6. RIGHTS OF THE LENDER.

     (a) If an Event of Default shall
occur and be continuing, all Proceeds received by the Pledgor shall be held by
the Pledgor in trust for the Lender, segregated from other funds of the Pledgor,
and shall, forthwith upon receipt by the Pledgor, he turned over to the Lender
in the exact form received by the Pledgor (duly indorsed by the Pledgor to the
Lender, if required). All money Proceeds received by the Lender hereunder shall
be held in a Collateral Account. All Proceeds while held by the Lender in a
Collateral Account (or by the Pledgor in trust for the Lender) shall continue to
be held as collateral security for all the Obligations and shall not constitute
payment thereof until applied as provided in paragraph (b).

     (b) If an Event of Default shall
occur and be continuing and the Lender shall give notice of its intent to
exercise such rights to the Pledgor, (1) the Lender shall have the right to
receive any and all cash dividends, payments or other Proceeds paid in respect
of the Pledged Interests and make application thereof to the Obligations in such
order as the Lender may determine, and (2) all of the Pledged Interests shall be
registered in the name of the Lender or its nominee, and the Lender or its
nominee may thereafter exercise (A) all voting and other rights pertaining to
the Pledged Interests at any meeting of members of the Borrower or otherwise and
(B) any and all rights of conversion, exchange, subscription and any other
rights, privileges or options pertaining to the Pledged Interests as if it were
the absolute owner thereof (including, without limitation, the right to exchange
at its discretion any and all of the Pledged Interests upon the merger,
consolidation, reorganization, recapitalization or other fundamental change in
the organizational structure of the Borrower, or upon the exercise by the
Pledgor or the Lender of any right, privilege or option pertaining to such
Pledged Interests, and in connection therewith, the right to deposit and deliver
any and all of the Pledged Interests with any committee, depositary, transfer
agent, registrar or other designated agency upon such terms and conditions as
the Lender may determine), all without liability except to account for property
actually received by it, but the Lender shall have no duty to the Pledgor to
exercise any such right, privilege or option and shall not be responsible for
any failure to do so or delay in so doing.

SECTION 7. REMEDIES.

-6-




     (a) Application of
Proceeds. If an Event of Default shall have occurred and be continuing, at
any time at the Lender's election, the Lender may apply all or any part of
Proceeds constituting Collateral, whether or not held in any Collateral Account,
in payment of the Obligations in such order as the Lender may elect.

     (b) Code and Other
Remedies. If an Event of Default shall have occurred and be continuing, the
Lender, may exercise, in addition to all other rights and remedies granted in
this Agreement and in any other instrument or agreement securing, evidencing or
relating to the Obligations, all rights and remedies of a secured party under
the Code or any other applicable law. Without limiting the generality of the
foregoing, the Lender, without demand of performance or other demand,
presentment, protest, advertisement or notice of any kind (except any notice
required by law referred to below) to or upon the Pledgor or any other Person
(all and each of which demands, defenses, advertisements and notices are hereby
waived), may in such circumstances forthwith collect, receive, appropriate and
realize upon the Collateral, or any part thereof, and/or may forthwith sell,
assign, give option or options to purchase or otherwise dispose of and deliver
the Collateral or any part thereof (or contract to do any of the foregoing), in
one or more parcels at public or private sale or sales, in the over-the-counter
market, at any exchange, broker's board or office of the Lender or elsewhere
upon such terms and conditions as it may deem advisable and at such prices as it
may deem best, for cash or on credit or for future delivery without assumption
of any credit risk. The Lender shall have the right upon any such public sale or
sales, and, to the extent permitted by law, upon any such private sale or sales,
to purchase the whole or any part of the Collateral so sold, free of any right
or equity of redemption in the Pledgor, which right or equity is hereby waived
or released. The Lender shall apply any Proceeds from time to time held by it
and the net proceeds of any such collection, recovery, receipt, appropriation,
realization or sale, after deducting all costs and expenses of every kind
incurred in respect thereof or incidental to the care or safekeeping of any of
the Collateral or in any way relating to the Collateral or the rights of the
Lender hereunder, including, without limitation, attorney's fees and
disbursements, to the payment in whole or in part of the Obligations, in such
order as the Lender may elect, and only after such application and after the
payment by the Lender of any other amount required by any provision of law, need
the Lender account for the surplus, if any, to the Pledgor. To the extent
permitted by applicable law, the Pledgor waives all claims, damages and demands
it may acquire against the Lender arising out of the exercise by them of any
rights hereunder. If any notice of a proposed sale or other disposition of
Collateral shall be required by law, such notice shall be deemed reasonable and
proper if given at least ten (10) days before such sale or other
disposition.

SECTION 8. [Intentionally omitted] 

SECTION 9. PRIVATE SALES.

     (a) The Pledgor recognizes that
the Lender may be unable to effect a public sale of any or all the Pledged
Interests, by reason of certain prohibitions under applicable federal and state
law or otherwise, and may be compelled to resort to one or more private sales
thereof to a restricted group of purchasers which will be obliged to agree,
among other things, to acquire such securities for their own account for
investment and not with a view to the distribution or resale thereof. The
Pledgor acknowledges and agrees that any such private sale may result in prices
and other terms less favorable than if such sale were a public sale and,
notwithstanding such circumstances, agrees that any such private sale shall be
deemed to have been made in a commercially reasonable manner. The Lender shall
be under no obligation to delay a sale of any

-7-




of the Pledged Interests for the period of time necessary to
permit the Borrower to register such securities for public sale under the
Securities Act, or under applicable state securities laws, even if the Borrower
would agree to do so.

     (b) The Pledgor further agrees to
use its best efforts to do or cause to be done all such other acts as may be
necessary to make such sale or sales of all or any portion of the Pledged
Interests pursuant to this Section valid and binding and in compliance with any
and all other applicable requirements of federal or state law. The Pledgor
further agrees that a breach of any of the covenants contained in this Section 9
will cause irreparable injury to the Lender, that the Lender has no adequate
remedy at law in respect of such breach and, as a consequence, that each and
every covenant contained in this Section 9 shall be specifically enforceable
against the Pledgor, and the Pledgor hereby waives and agrees not to assert any
defenses against an action for specific performance of such covenants.

SECTION 10. SUBORDINATION. The Pledgor hereby agrees that, upon
the occurrence and during the continuance of an Event of Default, unless
otherwise agreed by the Lender, all Indebtedness owing by it shall be fully
subordinated to the indefeasible payment in full in cash of the Obligations.

SECTION 11. IRREVOCABLE AUTHORIZATION AND INSTRUCTION TO
BORROWER. The Pledgor hereby authorizes and instructs the Borrower to comply
with any instruction received by it from the Lender in writing that (a) states
that an Event of Default has occurred and (b) is otherwise in accordance with
the terms of this Agreement, without any other or further instructions from the
Pledgor.

SECTION 12. LENDER'S APPOINTMENT AS ATTORNEY-IN-FACT.

     12.1 Lender's Appointment as
Attorney-in-Fact, etc.

          (a)
The Pledgor hereby irrevocably constitutes and appoints the Lender and any
officer or agent of the Lender, with full power of substitution, as its true and
lawful attorneyin-fact with full irrevocable power and authority in the place
and stead of the Pledgor and in the name of the Pledgor or in its own name, from
time to time in the Lender's discretion, for the purpose of carrying out the
terms of this Agreement, to take any and all appropriate action and to execute
any and all documents and instruments which may be necessary or desirable to
accomplish the purposes of this Agreement.

          (b)
If the Pledgor fails to perform or comply with any of its agreements contained
herein, the Lender, at its option, but without any obligation so to do, may
perform or comply, or otherwise cause performance or compliance, with such
agreement (and shall give the Pledgor notice thereof).

          (c)
The Pledgor hereby ratifies all that said attorneys shall lawfully do or cause
to be done by virtue hereof. All powers, authorizations and agencies contained
in this Agreement are coupled with an interest and are irrevocable until this
Agreement is terminated and the security interests created hereby are
released.

SECTION 13. DUTY OF LENDER. The Lender's sole duty with respect
to the custody, 

-8-




safekeeping and physical preservation of the Collateral in its
possession shall be to deal with it in the same manner as the Lender deals with
similar securities and property for its own account.

-9-




Neither the Lender nor any of its directors, officers,
employees or agents shall be liable for failure to demand, collect or realize
upon any of the Collateral or for any delay in doing so or shall be under any
obligation to sell or otherwise dispose of any Collateral upon the request of
the Pledgor or any other Person or to take any other action whatsoever with
regard to the Collateral or any part thereof. The powers conferred on the Lender
hereunder are solely to protect the Lender's interests in the Collateral and
shall not impose any duty upon the Lender to exercise any such powers. The
Lender shall be accountable only for amounts that it actually receives as a
result of the exercise of such powers, and neither it nor any of its officers,
directors, employees or agents shall be responsible to the Pledgor for any act
or failure to act hereunder.

SECTION 14. EXECUTION OF FINANCING STATEMENTS. The Pledgor
hereby irrevocably authorizes the Lender to file or record at any time and from
time to time in any jurisdiction in which the Code has been adopted initial
financing statements or amendments thereof and other filing or recording
documents or instruments with respect to the Collateral without the signature of
the Pledgor in such form and in such filing offices as the Lender determines
appropriate. The Pledgor hereby ratifies and authorizes the filing by the Lender
of any financing statement with respect to the Collateral made prior to the date
hereof. A carbon, photographic or other reproduction of this Agreement shall be
sufficient as a financing statement for filing in any jurisdiction.

SECTION 15. NOTICES. All notices, requests and demands to or
upon the Lender or the Pledgor to be effective shall be in writing (or by telex,
fax or similar electronic transfer confirmed in writing) and shall be deemed to
have been duly given or made (1) when delivered by hand or (2) if given by mail,
three (3) days after being deposited in the mails by certified mail, return
receipt requested, or (3) if by telex, fax or similar electronic transfer, when
sent and receipt has been confirmed, addressed to the Lender or the Pledgor at
its address or transmission number for notices as set forth below.

SECTION 16. SEVERABILITY. Any provision of this Agreement which
is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any

     (c) agrees that service of
process in any such action or proceeding may be effected by mailing a copy
thereof by registered or certified mail (or any substantially similar form of
mail), postage prepaid, to the Pledgor at its address referred to in Section 15
or at such other address of which the Lender shall have been notified pursuant

relinquishes, to the maximum extent permitted by applicable law, all rights and

require the Lender to proceed against any Person or to proceed against or
exhaust any security held by the Lender at any time or to pursue any other
remedy in the Lender's powers before proceeding against Pledgor; (ii) any
defense that may arise by reason of the incapacity, lack of power or authority,
death, dissolution, merger, termination or disability of Pledgor or any other
Person or the failure of the Lender to file or enforce a claim against the
estate (in administration, bankruptcy or any other proceeding) of Pledgor or any
other Person; (iii) any right to enforce any remedy that the Lender may have
against any Person and any right to participate in any security

-14-




held by the Lender until the Obligations have been paid in
full; (iv) any right to require the Lender to give any notices of any kind,
including, without limitation, notices of nonpayment, nonperformance, protest,
dishonor, default, delinquency or acceleration, or to make any presentments,
demands or protests; (v) any right to assert the bankruptcy or insolvency of any
Person as a defense hereunder or as the basis for rescission hereof and any
defense arising because of the Lender's election, in any proceeding instituted
under the Bankruptcy Code, of the application of Section 1111(b)(2) of the
Bankruptcy Code; (vi) any right under any law purporting to reduce Pledgor's
obligations hereunder if the Obligations are reduced other than as a result of
payment of such Obligations; (vii) any defense based on the repudiation of the
Loan Documents by any Person, the failure by the Lender to enforce any claim
against Pledgor or any other Person or the unenforceability in whole or in part
of any Loan Document; (viii) all suretyship and guarantor's defenses generally;
(ix) any right to insist upon, plead or in any manner whatever claim or take the
benefit or advantage of, any appraisal, valuation, stay, extension, marshaling
of assets, redemption or similar law, or exemption, whether now or at any time
hereafter in force, which may delay, prevent or otherwise affect the performance
by Pledgor of its obligations under, or the enforcement by the Lender of, this
Agreement; (x) any requirement on the part of the Lender to mitigate the damages
resulting from any default; (xi) any defense based upon an election of remedies
by the Lender, including an election to proceed by non judicial rather than
judicial foreclosure, which destroys or otherwise impairs the subrogation rights
of Pledgor, the right of Pledgor to proceed against another Person for
reimbursement, or both; (xii) any duty on the part of the Lender to disclose to
Pledgor any facts the Lender may now or hereafter know, regardless of whether
the Lender has reason to believe that any such facts materially increase the
risk beyond that which Pledgor intends to assume, or has reason to believe that
such facts are unknown to Pledgor, or has a reasonable opportunity to
communicate such facts to Pledgor; (xiii) any defense based on any change in the
time, manner or place of any payment under, or in any other term of, the Loan
Documents or any other amendment, renewal, extension, acceleration, compromise
or waiver of or any consent or departure from the terms of the Loan Documents;
and (xiv) any defense based upon any borrowing or grant of a security interest
under Section 364 of the Bankruptcy Code.

     (b) To the extent permitted by
law, Pledgor waives the posting of any bond otherwise required of the Lender in
connection with any judicial process or proceeding to obtain possession of,
replevy, attach, or levy upon the Collateral, to enforce any judgment or other
security for the Obligations, to enforce any judgment or other court order
entered in favor of the Lender, or to enforce by specific performance, temporary
restraining order, preliminary or permanent injunction, this Agreement or any
other agreement or document between Pledgor and the Lender. Pledgor further
agrees that upon the occurrence and during the continuation of an Event of
Default, the Lender may elect to nonjudicially or judicially foreclose against
any real or personal property security it holds for the Obligations or any part
thereof; or to exercise any other remedy against any Person, any security or any
guarantor, even if the effect of that action is to deprive Pledgor of the right
to collect reimbursement from any Person for any sums paid by Pledgor to the
Lender.

and "hereunder" and words of similar import when used in this Agreement shall

Agreement, and section and paragraph references are to this Agreement unless
otherwise specified.

Litigation

In December 2006, an Affiliate of the Borrower and its former
drilling contractor agreed to the binding arbitration process under the laws of
the State of Nevada in order to resolve certain disputes regarding drilling
services rendered. The maximum amount under dispute approximates $900,000 USD.
The Borrower is confident that the amounts owing are substantially less and
accordingly has accrued a smaller amount; however the outcome of the arbitration
process is not presently determinable.
