Seller shall defend, indemnify and hold harmless Buyer and its respective
permitted assigns and agents, employees, officers, directors, shareholders,
subsidiaries and Affiliates and anyone else acting for or on behalf of Buyer and
their permitted assigns ("Buyer Indemnitees"), from and against all Damages
(excluding incidental or consequential damages incurred by Buyer Indemnitees;
provided, however, that such exclusion shall not apply to any third party claim
against Buyer Indemnitees) suffered, sustained or incurred by Buyer Indemnitees
as a result of or arising out of, or in connection with (i) any breach of any
Seller's representation, warranty or covenant contained in Section 2 of this
Agreement, and (ii) any distributions due to Far West Capital, Inc. under the
Operating Agreement accruing on or before the Closing Date of the transaction
contemplated


                                       6



hereby. Damages means all liabilities, assessments, levies, losses, fines,
penalties, damages, costs and expenses or any kind or character. Without
limiting the generality of the foregoing, Damages include reasonable attorneys',
arbitrators', accountants', investigators', environmental consultants' and
experts' fees and expenses, sustained or incurred in connection with the
enforcement or defense by an Indemnitee of its rights and remedies under this
Agreement or any agreement, instrument or document executed or to be delivered
in connection with this Agreement. Indemnification under this section shall be
the sole remedy of the Buyer Indemnitees for items for which indemnification is
provided under this section (other than actual fraud).

               (b) Subject to the following provisions of this Section 12, Buyer
shall defend, indemnify and hold harmless Seller and its permitted assigns and
agents, employees, officers, directors, shareholders, subsidiaries and
Affiliates and anyone else acting for or on behalf of Seller and its permitted
assigns ("Seller Indemnitees"), from and against all Damages (excluding
incidental or consequential damages incurred by Seller Indemnitees; provided,
however, that such exclusion shall not apply to any third party claim against
Seller Indemnitees) sustained or incurred by Seller as a result of or arising
out of, or in connection with (i) any breach of any Buyer's representation,
warranty or covenant contained in this Agreement (ii) except as set forth in
Section 12(a) hereof, the operation of the business of the Company after the
time of Closing on the Closing Date. Indemnification under this section shall be
the sole remedy of Seller Indemnitees for items for which indemnification is
provided under this section (other than for actual fraud).

               (c) The parties hereto agree that the provisions of this Section
12 shall govern any claims for indemnification under this Agreement. If and when
an indemnified party desires to assert a claim for Damages against an
indemnifying party pursuant to the provisions of this Agreement, the indemnified
party shall deliver to the indemnifying party reasonably promptly after its
receipt of a claim or specific and affirmative awareness of a potential claim, a
certificate signed by the indemnified party (the "Notice of Claim"): (i) stating
the amount of Damages (to the extent then known); and, (ii) specifying to the
extent possible (A) the individual items of Damages included in the amount so
stated, (B) the date each such item is to be paid or accrued and (C) the basis
upon which Damages are claimed. The indemnified party and the indemnifying party
shall proceed, in good faith, and using reasonable efforts, to agree upon the
amount of such Damages. If the indemnifying party does not notify the
indemnified party within thirty (30) days of the giving of such Notice of Claim
that the indemnifying party disputes such Damages, the amount of such Damages
shall be conclusively deemed a liability of the indemnifying party hereunder.

               (d) Each and every controversy or claim arising out of or
relating to indemnification for Damages pursuant to Section 12(a) or 12(b) of
this Agreement which the indemnifying Party and the indemnified Party (the
"Parties") have not resolved by themselves shall first be referred to a
non-binding mediation to be held in Reno, Nevada before a certified mediator
reasonably acceptable to both Parties. Such mediation shall be held within 30
calendar days of the written request of one of the Parties for such mediation.
The Parties shall split the fees for such mediation and otherwise bear their own
costs.

               (e) If either party shall receive notice or have knowledge of any
third party action that may result in a claim for indemnification against the
other party pursuant to this Section (a "Claim"), such party shall promptly give
the other party notice of such Claim. The


                                       7



parties shall consult and cooperate with each other regarding the response to
and defense of such Claim, and the indemnifying party shall be entitled to
assume the defense in respect of such Claim, including the right to select and
direct legal counsel and to accept or reject offers of settlement, all at its
sole cost and expense, provided that no such settlement shall be made without
the written consent of the Parties, such consent not to be unreasonably
withheld. Nothing herein shall prevent an indemnified party from retaining its
own counsel and participating in its own defense at its own cost and expense.

               (f) The indemnitees set forth in Section 12 shall survive the
Closing only as to Claims for indemnification that are made within 27 months of
the Closing.

               (g) Notwithstanding anything contained herein, in no event shall
the aggregate amount of indemnification payable by the Buyer to Seller
Indemnitees or by the Seller to Buyer Indemnitees, exceed the Purchase Price.
The parties agree that the amount of any indemnification payment otherwise
required to be made by the Buyer or the Seller hereunder shall be determined net
of insurance proceeds. In particular, the amount of an indemnification payment
shall be (i) the amount of the Damages (determined without regard to insurance
proceeds or tax adjustments), (ii) minus any insurance payments received by the
indemnified person attributable to the Damages.

          13. TAXES.

               (a) Transfer Taxes. Seller, on the one hand, and Buyer, on the
other, shall bear in equal portions and pay all sales, use, transfer, recording,
gains, stock transfer and other similar taxes and fees ("Transfer Taxes") if
any, arising out of or in connection with the sale of the Target Interest
pursuant to this Agreement.

               (b) Refunds. Any refund or credit of pre-closing taxes or overlap
period taxes paid by Seller on account of the Target Interest shall be for the
benefit of Seller. Company shall pay any such refund to Seller within thirty
(30) days after the Company receives such refund or actually realize the benefit
of such credit.

                  AGREEMENT REGARDING USE OF FIRE WATER SUPPLY

     This Agreement Regarding Use of Water Supply (this "Agreement") is entered
into this ______ day of _______________, 2003, by and between Steamboat
Development Corp. ("SDC"), a Utah corporation, and US Energy Geothermal, LLC
("SB1/1A"), a Delaware limited liability company.

                                    RECITALS

     A.   SB1/1A has a 200,000 gallon water storage tank (the "Tank") and diesel
          pump (the "Pump") maintained for fire-fighting purposes at its
          Steamboat Springs geothermal plant site ("Steamboat 1"), approximately
          10 miles south of Reno, Nevada.

     B.   SDC has built two 12 MW geothermal power plants ("Steamboat 2 & 3") on
          the Towne Lease immediately adjacent to the east of Steamboat 1.

     C.   SDC desires to contract with SB1/1A the use of the Tank and the Pump
          exclusively for purposes of feeding fire water to the fire-fighting
          system for Steamboat 2 & 3.

     D.   The purpose of this Agreement is to provide the terms and conditions
          under which SDC will be able to connect with and utilize the Tank and
          the Pump, as described above.

                                    AGREEMENT

     Now therefore, based on the foregoing and the mutual covenants contained
herein and for other good and valuable consideration, the receipt and adequacy
of which are hereby acknowledged, the parties hereto agree as follows:

     1.   SB1/1A hereby grants to SDC the right to connect to and utilize, on a
          non-exclusive basis, the Tank, the Pump and directly related piping,
          without interfering with SB1/1A's activities, exclusively for purposes
          of feeding the fire-fighting system in a reasonable manner at the
          Steamboat 2 & 3 power plants, subject to the availability of water and
          the making of all payments as provided in paragraph 2 below.

     2.   As consideration for the right granted in paragraph 1 above, SDC
          agrees to pay all costs and expenses involved in 1) replacing water as
          needed to keep


                                        2



          the Tank full, 2) maintaining and testing the Tank, the Pump and
          related piping as reasonably necessary to ensure that they are
          constantly in proper working order, and 3) connecting to and utilizing
          the Tank, the Pump and related piping.

     3.   The term of such right shall be for 30 years from the date hereof and
          for so long thereafter as each party hereto owns and operates its
          respective geothermal power plant, provided that this Agreement shall
          terminate automatically if the Tank, the Pump or related piping are
          destroyed or damaged, unless corrective action is funded by SDC in
          full.

     4.   This Agreement is binding on the heirs, successors and permitted
          assigns of the parties hereto.

     5.   This Agreement contains the entire agreement of the parties hereto
          with respect to the subject matter agreed to herein and shall not be
          amended or modified except by a writing signed by authorized
          representatives of each party hereto.

     6.   In the event of a dispute between the parties with respect to the
          interpretation or enforcement of any provision of this Agreement, it
          is agreed that action shall be brought exclusively in the Nevada state
          court having subject matter jurisdiction located in Reno, Nevada and
          that the prevailing party shall be entitled to reasonable attorney's
          fees in addition to any other relief to which that party may be
          entitled.

     7.   THE PARTIES AGREE THAT ALL OTHER PREVIOUS AGREEMENTS RESPECTING THE
          RIGHTS OF SDC TO USE THE FIRE WATER FACILITIES DESCRIBED HEREIN ARE,
          AND HAVE BEEN TERMINATED. SB1/1A ARE RELEASED FROM ANY LIABILITIES AND
          CLAIMS THEREUNDER.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement the day
and year first above written.
