	(3) 	If, at any time during the term of this Agreement,
        the Escrow Agent is prohibited from releasing escrow securities on a release
        date specified schedule B(4) as a result of section 2.3(2) above, then

        then: 

	 	 

	 	 (a) 
	the Escrow Agent will deliver a notice to the Issuer,
        and will include with the notice any certificates that the Escrow Agent
        holds which evidence the escrow securities; and 

      
	 	 	 
	 	 (b)

	 the Issuer and the Escrow Agent will take such action as is necessary

 PART 3           EARLY RELEASE
  ON CHANGE OF ISSUER STATUS  

 3.1          Early Release
  – Graduation to Tier 1 

	(1) 	When a Tier 2 Issuer becomes a Tier 1 Issuer, the
        release schedule for its escrow securities changes. 

	 	 
	(2)	 If the Issuer reasonably believes that it meets
        the Minimum Listing Requirements of a Tier 1 Issuer as described in Policy
        2.1 – Minimum Listing Requirements, the Issuer may make
        application to the Exchange to be listed as a Tier 1 Issuer. The Issuer
        must also concurrently provide notice to the Escrow Agent that it is making
        such an application. 

	 	 
	(3)	 If the graduation to Tier 1 is accepted by the Exchange,
        the Exchange will issue an Exchange Bulletin confirming final acceptance
        for listing of the Issuer on Tier 1. Upon issuance of this Bulletin the
        Issuer must immediately: 

	 	 

	 	(a)	 issue a news release: 
	 	 	 

	 	 	(i) 	disclosing that it has been accepted for graduation to Tier 1; and 
	 	 	 	 
	 	 	(ii) 	disclosing the number of escrow securities to be
        released and the dates of release under the new schedule; and 

	 	 	 	 
	 	(b)	 provide the news release, together with a copy
      of the Exchange Bulletin, to the Escrow Agent. 
	 	 	 	 

	(4) 	Upon completion of the steps in section 3.1(3) above,
        the Issuer’s release schedule will be replaced as follows: 

	Applicable Schedule Pre-Graduation	Applicable Schedule Post-Graduation
	Schedule B(2)	Schedule B(1)

	(5) 	Within 10 days of the Exchange Bulletin confirming
        the Issuer’s listing on Tier 1, the Escrow Agent must release any
        escrow securities from escrow securities which under the new release schedule
        would have been releasable at a date prior to the Exchange Bulletin. 

PART 4           DEALING WITH
  ESCROW SECURITIES  

 4.1           Restriction
  on Transfer, etc.  

 Unless it is expressly permitted in this Agreement, you will
  not sell, transfer, assign, mortgage, enter into a derivative transaction concerning,
  or otherwise deal in any way with your escrow 

	 
	FORM 5D	ESCROW AGREEMENT	Page 5

	(as at August 2002)	 	 

 securities or any related share certificates or other evidence
  of the escrow securities. If a Securityholder is a private company controlled
  by one or more Principals of the Issuer, the Securityholder may not participate
  in a transaction that results in a change of its control or a change in the
  economic exposure of the Principals to the risks of holding escrow securities.

 4.2          Pledge,
  Mortgage or Charge as Collateral for a Loan  

 Subject to Exchange acceptance, you may pledge, mortgage or
  charge your escrow securities to a financial institution as collateral for a
  loan, provided that no escrow securities or any share certificates or other
  evidence of escrow securities will be transferred or delivered by the Escrow
  Agent to the financial institution for this purpose. The loan agreement must
  provide that the escrow securities will remain in escrow if the lender realizes
  on the escrow securities to satisfy the loan. 

 4.3          
  Voting of Escrow Securities  

 Although you may exercise voting rights attached to your escrow
  securities, you may not, while your securities are held in escrow, exercise
  voting rights attached to any securities (whether in escrow or not) in support
  of one or more arrangements that would result in the repayment of capital being
  made on the escrow securities prior to a winding up of the Issuer. 

 4.4          
  Dividends on Escrow Securities  

 You may receive a dividend or other distribution on your escrow
  securities, and elect the manner of payment from the standard options offered
  by the Issuer. If the Escrow Agent receives a dividend or other distribution
  on your escrow securities, other than additional escrow securities, the Escrow
  Agent will pay the dividend or other distribution to you on receipt. 

 4.5          
  Exercise of Other Rights Attaching to Escrow Securities  

 You may exercise your rights to exchange or convert your escrow
  securities in accordance with this agreement.

	(4) 	If the Issuer is a Tier
        2 Issuer and the successor issuer is a Tier 1 Issuer, the release provisions

        Issuer will be responsible for ensuring that the Escrow Agent is replaced
        not later than the resignation or termination date by another escrow agent
        that is acceptable to the Exchange and that has accepted such appointment,
        which appointment will be binding on the Issuer and the Securityholders.
        

          

	(4) 	The resignation or termination of the Escrow Agent
        will be effective, and the Escrow Agent will cease to be bound by this
        Agreement, on the date that is 60 days after the date of receipt of the
        notices referred to above by the Escrow Agent or Issuer, as applicable,
        or on such other date as the Escrow Agent and the Issuer may agree upon
        (the “resignation or termination date”), provided that the resignation
        or termination date will not be less than 10 business days before a release
        date. 

          

	(5) 	If the Issuer has not appointed a successor escrow
        agent within 60 days of the resignation or termination date, the Escrow
        Agent will apply, at the Issuer’s expense, to a court of competent
        jurisdiction for the appointment of a successor escrow agent, and the
        duties and responsibilities of the Escrow Agent will cease immediately
        upon such appointment.

        Escrow Agent will be vested 

	 
	FORM 5D	ESCROW AGREEMENT	Page 13

	(as at August 2002)	 	 

 with the same powers, rights, duties
  and obligations as if it had been originally named herein as Escrow Agent, without
  any further assurance, conveyance, act or deed. The predecessor Escrow Agent,
  upon receipt of payment for any outstanding account for its services and expenses
  then unpaid, will transfer, deliver and pay over to the successor Escrow Agent,
  who will be entitled to receive, all securities, records or other property on
  deposit with the predecessor Escrow Agent in relation to this Agreement and
  the predecessor Escrow Agent will thereupon be discharged as Escrow Agent.

	(7) 	If any changes are made to Part 8 of this Agreement
        as a result of the appointment of the successor Escrow Agent, those changes
        must not be inconsistent with the Policy and the terms of this Agreement
        and the Issuer to this Agreement will file a copy of the new Agreement
        with the Exchange. 

PART 8           OTHER CONTRACTUAL
  ARRANGEMENTS  

 8.1           Escrow Agent
  Not a Trustee

  Agent Not Responsible for Furnished Information 

 The Escrow Agent will have no responsibility for seeking,

  any and all claims, demands, losses, penalties, costs, expenses, fees and liabilities,
  including, without limitation, legal fees and expenses, directly or indirectly

  or bad faith on the part 

	 
	FORM 5D	ESCROW AGREEMENT	Page 14

	(as at August 2002)	 	 

 of the Escrow Agent. This indemnity survives the release of
  the escrow securities, the resignation or termination of the Escrow Agent and
  the termination of this Agreement. 

 8.6          Additional Provisions
   

 (1) The Escrow Agent will be protected in acting and relying
  reasonably upon any notice, direction, instruction, order, certificate, confirmation,
  request, waiver, consent, receipt, statutory declaration or other paper or document
  (collectively referred to as “Documents”) furnished to it and
  purportedly signed by any officer or person required to or entitled to execute
  and deliver to the Escrow Agent any such Document in connection with this Agreement,
  not only as to its due execution and the validity and effectiveness of its provisions,
  but also as to the truth or accuracy of any information therein contained, which
  it in good faith believes to be genuine. 

 (2) The Escrow Agent will not be bound by any notice of a
  claim or demand with respect thereto, or any waiver, modification, amendment,
  termination or rescission of this Agreement unless received by it in writing,
  and signed by the other Parties and approved by the Exchange, and, if the duties
  or indemnification of the Escrow Agent in this Agreement are affected, unless
  it has given its prior written consent. 

 (3) The Escrow Agent may consult with or retain such legal
  counsel and advisors as it may reasonably require for the purpose of discharging
  its duties or determining its rights under this Agreement and may rely and act
  upon the advice of such counsel or advisor. The Escrow Agent will give written
  notice to the Issuer as soon as practicable that it has retained legal counsel
  or other advisors. The Issuer will pay or reimburse the Escrow Agent for any
  reasonable fees, expenses and disbursements of such counsel or advisors. 

 (4) In the event of any disagreement arising under the terms
  of this Agreement, the Escrow Agent will be entitled, at its option, to refuse
  to comply with any and all demands whatsoever until the dispute is settled either
  by a written agreement among the Parties or by a court of competent jurisdiction.

 (5) The Escrow Agent will have no duties or responsibilities
  except as expressly provided in this Agreement and will have no duty or responsibility
  under the Policy or arising under any other agreement, including any agreement
  referred to in this Agreement, to which the Escrow Agent is not a party. 

 (6) The Escrow Agent will have the right not to act and will
  not be liable for refusing to act unless it has received clear and reasonable
  documentation that complies with the terms of this Agreement. Such documentation
  must not require the exercise of any discretion or independent judgment.

  delivered to it and hold such Securityholder’s escrow securities in electronic,
  or uncertificated form only, pending release of such securities from escrow.

 (8) The Escrow Agent will have no responsibility with respect
  to any escrow securities in respect of which no share certificate or other evidence
  or electronic or uncertificated form of 

	 
	FORM 5D	ESCROW AGREEMENT	Page 15

	(as at August 2002)	 	 

these securities has been delivered to it, or otherwise received by it.

 8.7          Limitation of
  Liability of Escrow Agent  

 The Escrow Agent will not be liable to any of the Parties
  hereunder for any action taken or omitted to be taken by it under or in connection
  with this Agreement, except for losses directly, principally and immediately
  caused by its bad faith, wilful misconduct or gross negligence. Under no circumstances
  will the Escrow Agent be liable for any special, indirect, incidental, consequential,
  exemplary, aggravated or punitive losses or damages hereunder, including any
  loss of profits, whether foreseeable or unforeseeable. Notwithstanding the foregoing
  or any other provision of this Agreement, in no event will the collective liability
  of the Escrow Agent under or in connection with this Agreement to any one or
  more Parties, except for losses directly caused by its bad faith or wilful misconduct,
  exceed the amount of its annual fees under this Agreement or the amount of three
  thousand dollars ($3,000.00), whichever amount shall be greater. 

 8.8           Remuneration
  of Escrow Agent 

 The Issuer will pay the Escrow Agent reasonable remuneration

  time to time on 30 days' written notice. The Issuer will reimburse the Escrow
  Agent for its expenses and disbursements. Any amount due under this section
  and unpaid 30 days after request for such payment, will bear interest from the
  expiration of such period at a rate per annum equal to the then current rate
  charged by the Escrow Agent, payable on demand.

  forth in Section 2.1 shall have been satisfied, the following additional restrictions
  shall apply to the escrow securities:

	      Total:	1,000,000	750,000	250,000

   

	 	 	The first tranche will be released at such time as
        the Issuer has: (i) obtained all material permits and licenses necessary
        to authorize the Issuer, or an affiliate of the Issuer, to begin construction
        of a 10 megawatt power plant, (ii) entered into a power purchase agreement
        to sell at standard commercial prices the power to be generated by such
        power plant, and (iii) entered into a power transmission agreement to
        transmit the power to be generated by such power plant, provided all of
        the foregoing shall have occurred by June 19, 2005. 

       The second tranche will be released at such time as
        the Issuer has: (i) obtained all material permits and licenses necessary
        to authorize the Issuer, or an affiliate of the Issuer, to begin construction
        of (or to expand its existing facility or authorization to) a 15 megawatt
        power plant, (ii) entered into a power purchase agreement to sell at standard
        commercial prices the power to be generated by such power plant, and (iii)

        to such criteria, as applicable, shall be returned to the Issuer and cancelled;

          

	 	(d) 	for the purposes of determining whether or not subsections
        8.9 (1) (a) and (b) above have or have not been satisfied, the Escrow
        Agent shall be entitled to rely on a statutory declaration of an independent
        director of the Issuer confirming that the release criteria set forth
        in subsection (a) or (b) have or have not been satisfied, as the case
        may be. The Escrow Agent shall promptly provide a copy of each statutory
        declaration that it receives pursuant to this subsection to the Issuer
        and to each holder of escrow securities under this Agreement. For the
        purposes hereof, a director is not independent if the director or a shareholder
        that has appointed the director will receive a release of escrowed securities
        as a consequence of the Escrow Agent relying on the statutory declaration
        sworn by such director; and 

          

	 	(e) 	the Escrow Agent shall wait five business days after
        receiving any statutory declaration pursuant to this section 8.9 before
        taking any action in respect thereof, other than sending copies of the
        statutory declaration to the Issuer and each holder of escrow securities
        under this Agreement.

              FIRST
  AMENDED AND RESTATED MERGER AGREEMENT, dated effective November 20, 2003 (the
  “First Amendment”), by and among U.S. Cobalt Inc., a Delaware
  corporation (the “Company”), EverGreen Power Inc., an Idaho
  corporation and a wholly-owned subsidiary of the Company (“Sub”),
  U.S. Geothermal Inc., an Idaho corporation (“Geo”), and the
  stockholders of Geo set forth on the signature pages hereto (collectively, the
  “Principal Geo Shareholders”). Geo and Sub are sometimes herein
  collectively referred to as the “Constituent Corporations.”

 RECITALS 

              A.
  Geo is engaged in the business of acquiring and developing one or more geothermal
  projects (the “Business”). 

              B.
  The Company, Sub and Geo desire to effect a merger (“Merger”)
  of Sub with Geo, pursuant to which (i) subject to Sections 2.1(f) and 2.5 hereof,
  (a) each share of Geo’s common stock, $.001 par value per share (“Geo
  Common Stock”) will be converted into shares of the voting Common Stock
  of the Company, $.001 par value per share (“Company Common Stock”),
  and (b) all outstanding common share purchase warrants of Geo will be converted
  into warrants to purchase Company Common Stock and (ii) the Company will become
  the sole stockholder of the Surviving Corporation (as defined below). 

              C.
  The Boards of Directors of the Company, Sub and Geo have each approved the Merger

  and in the best interests of their respective stockholders that the Merger be
  consummated. 

              D.
  For federal income tax purposes, it is intended that the Merger shall qualify
  as a reorganization within the meaning of Section 368(a)(2)(E) of the Internal
  Revenue Code of 1986, as amended (the “Code”). 

              E.
  Effective February 28, 2003, the parties entered into a Merger Agreement (the
  “Agreement”), to memorialize the terms of the Merger. Since
  that time, certain facts and circumstances have changed, and the parties wish
  to amend and restate the Agreement to reflect their agreement with and to such
  changes. 

              F.
  Capitalized terms used herein are defined or their definitions are referenced
  on Schedule E hereto.

  the Exchange and Escrow Agent (the “Escrow Agreement(s)”).

  Equitable Adjustments. Notwithstanding the foregoing, the number of shares
  of Company Common Stock and Exchange Warrants to be issued pursuant to Sections
  2.1(c) and 2.1(d) of this First Amendment (including the number of Escrow Securities)

  2.2. Dissenters’ Rights. It is a condition to the obligations of
  the Company and Sub to proceed to closing under this First Amendment that no
  Geo Shareholders exercise any dissenters’ rights under applicable law.
  If such condition is waived (but without creating or implying any obligation
  to do so), the Geo Shareholders as to which dissenters’ rights shall have
  been duly demanded under applicable law (“Dissenting Shares”),
  if any, shall be entitled to payment by the Surviving Corporation only of the
  fair value of such shares plus accrued interest to the extent permitted by and
  in accordance with the provisions of applicable law; provided, however,
  that (i) if any holder of Dissenting Shares shall, under the circumstances permitted
  by applicable law, subsequently deliver a written withdrawal of such holder’s
  demand or (ii) if any holder fails to establish such holder’s entitlement
  to demand or receive payment as provided under applicable law, such holder or
  holders (as the case may be) shall forfeit such right to payment for such Geo
  Securities and such securities shall thereupon be deemed to have been converted
  into Company Common Stock as of the Effective Time in accordance with Section
  2.1 hereof (including, without limitation, that such shares of Company Common
  Stock shall constitute additional Escrow Securities subject to the terms of
  the Escrow in accordance with Section 2.1(e)). 

              SECTION
  2.3. No Fractional Shares. No certificates representing fractional shares
  of Company Common Stock shall be issued upon the surrender for exchange of certificates
  formerly representing Geo Common Stock or deposited into the Escrow pursuant

  any, the rights of the holder as provided in Section 2.2 or (ii) in all other
  cases, the right to receive Merger Consideration pursuant to and in accordance
  with the terms hereof and any holder thereof shall cease to have any rights
  as a securityholder of Geo or the Surviving Geo. 

              (b)

  or authorized stock appreciation, phantom stock or similar rights with respect
  to Geo. Geo is not subject to any obligation (contingent or otherwise) to repurchase
  or otherwise acquire or retire any shares of its capital stock. Geo has delivered

  and changes in cash flows for the period from Geo’s inception until September
  30, 2002, and the notes and supplementary information thereto, accompanied by
  the report thereon of Geo’s independent public accountant (such financial

  The Financial Statements and each item therein, including the notes thereto
  (i) were prepared in accordance with generally accepted accounting principles
  in the United States of America applied on a consistent basis throughout the
  periods covered thereby (“GAAP”), (ii) present fairly the financial
  position, results of operations and changes in cash flows, as applicable, of
  Geo, (iii) are accurate, correct and complete and are, in all material respects,

- 7 -

 existing condition, situation or set of circumstances which
  is reasonably likely to result in such a Liability, commitment or obligation,
  other than (x) Liabilities, commitments and obligations to the extent and in
  the amounts set forth on the Most Recent Balance Sheet (none of which results
  from, arises out of, relates to, is in the nature of or was caused by any breach
  of contract, breach of warranty, tort, infringement or violation of law), (y)
  obligations to perform the executory portions of contracts to which Geo is a
  party, provided that such obligations are set forth in such contracts, such
  contracts are set forth on Schedule 3.14 hereto, and such contracts were entered
  into in the ordinary course of business and have been made available to the
  Company, and (z) additional accruals of Liabilities of the type that would be
  included on a balance sheet of Geo in accordance with GAAP incurred in the ordinary
  course of business consistent with past practices subsequent to the date of
  the Most Recent Balance Sheet and prior to the date hereof or the Closing Date
  (as applicable), provided that none of such additional accruals results from,
  arises out of, relates to, is in the nature of, or was caused by any breach
  of contract, breach of warranty, tort, infringement or violation of law or relates
  to indebtedness for borrowed money or inter-company debt or debt owed to Affiliates
  and such additional accruals are not, in the aggregate, material.

              SECTION
  3.11. Absence of Certain Changes. Except as set forth on Schedule 3.11
  hereto, since September 30, 2002, Geo has conducted its businesses only in the
  ordinary and usual course using its best efforts to maintain and enhance the
  Business and there has been no material adverse change in the assets, properties,
  business, operations, prospects, customer, licensor, licensee, supplier or employee
  relations, net income or condition (financial or otherwise) of Geo or in the
  ability of Geo or any of the Principal Geo Shareholders to perform this First
  Amendment, the Additional Agreements and the transactions contemplated hereby
  and thereby (a “Material Adverse Effect”). For purposes of
  this First Amendment, any change or effect exceeding an amount or value or having
  an impact of $5,000 or more individually, or $10,000 or more in the aggregate,
  or adversely affecting Geo’s rights under the Geothermal Agreements or
  the Vulcan Agreement, shall be deemed to be “material” and result
  in a Material Adverse Effect. There is no event, condition, circumstance or,
  to the Knowledge of Geo or any Principal Geo Shareholder, prospective development
  which has had or may have a Material Adverse Effect. Without limiting the generality
  of the foregoing, except as set forth on Schedule 3.11 hereto, Geo has not since

  as required by applicable law, or (ii) entered into any employment, severance
  or termination agreement with any such Person,

             
  (h)  made any loan, advance or capital contribution to any Person,

  other such actions, will not have a Material Adverse Effect,

  other than in the ordinary course of business consistent with past practices,
  or

  or any of its officers, directors, stockholders, employees or agents involving,
  affecting or relating to the business, assets, operations or securities of Geo,
  or the transactions contemplated by this First Amendment or the Additional Agreements,
  nor is there any basis for any such Claim. Neither Geo nor any of its businesses,
  assets or properties is subject to any order, writ, judgment, award, injunction
  or decree of any Governmental Authority or arbitrator. No present or former
  employee of Geo (or any predecessor of its business) has made or is entitled
  to assert any Claim against Geo.

              SECTION
  3.13. Assets; Liens and Encumbrances. Geo has never held and does not

  property assets. There are no Liens with respect to Geo, its assets, businesses
  or operations except for Liens (a) for taxes not yet delinquent or the validity
  of which are being contested in good faith by appropriate actions, and (b) on
  assets leased or licensed by Geo as described in any Schedule hereto, in which
  case Geo holds a leasehold or licensed interest free and clear of all other
  Liens except for the lessor’s or licensor’s interest therein. Neither
  Geo nor any of the Principal Geo Shareholders are aware of (i) any assets of
  Geo which require substantial repair or replacement, (ii) any manufacturer,
  supplier or servicer of any assets of Geo which has terminated its operations
  or suffered a significant adverse change in its condition (financial or otherwise)
  or (iii) any other facts or circumstances which would materially adversely affect
  the Surviving Corporation’s ability to obtain repair or replacement products,
  parts or services with respect to any assets of Geo after the Closing.

              SECTION

  of business (consistent with past practices). Each of the Contracts is valid
  and binding and in full force and effect and is enforceable against the parties
  thereto in accordance with its terms, and there are no existing defaults or

  or consent or approval of any party, will not constitute a default under or
  a breach of any provisions of any Contracts and the Company and the Surviving

ARTICLE VII

RESTRICTIVE COVENANTS.

              In
  consideration of the Merger Consideration, each of the Principal Geo Shareholders
  covenants with the Company as follows: 

              SECTION
  7.1. Restrictions. Each Principal Geo Shareholder acknowledges that the
  Company has paid valuable consideration for Geo and its assets, particularly
  know-how, goodwill and other proprietary business information and trade secrets
  of Geo. The use by any Principal Geo Shareholder of these relationships and
  such confidential information in a business or activity which competes with
  the Company or its Affiliates would provide the competing business with an unfair
  advantage over the Company or its Affiliates. Accordingly, the Company wishes
  to restrict each Principal Geo Shareholder’s use of such information and
  each Principal Geo Shareholder’s ability to compete with the Company and
  its Affiliates. Each Principal Geo Shareholder agrees, for the Merger Consideration,
  to comply with the terms of this Article, all of which are reasonable and necessary
  to protect the confidential business information and trade secrets being acquired
  by the Company and to prevent any 

- 23 -

unfair advantage from being conferred upon a competing business of the Company or its Affiliate, as set forth below.

              SECTION
  7.2. Non-competition. For a period of three years from the date hereof,
  no Principal Geo Shareholder shall, directly or indirectly, either alone or
  as a stockholder, partner, consultant, owner, agent, creditor, coventurer of
  any other Person, or in any other capacity, directly or indirectly, engage in
  the Business within the State of Idaho; provided that nothing herein shall prohibit
  any Stockholder from being an owner of not more than 1% of the outstanding stock
  of any class of a corporation which is publicly traded, so long as such Principal
  Geo Shareholder does not actively participate in the business of such corporation.

              SECTION
  7.3. Non Interference with Business Relations. For a period of three
  years after the Closing Date, no Principal Geo Shareholder shall, directly or
  indirectly, solicit, induce or attempt to solicit or induce any customer, supplier,
  licensee, government agency, utility or other business relation of the Company
  or its Affiliates to cease doing business with the Company or its Affiliates,
  or in any way interfere with any such business relation of the Company or its
  Affiliates. 

              SECTION
  7.4. Solicitation of Customers and Employees. For a period of three years
  after the Closing Date, no Principal Geo Shareholder shall, directly or indirectly,
  either alone or as a stockholder, partner, consultant, adviser, owner, agent,
  creditor, coventurer of any other Person, or in any other capacity, solicit,
  hire, attempt to solicit or hire, or participate in any attempt to solicit or
  hire any person who was an employee of Geo or any of its Affiliates as of the
  Closing Date or within the six-month period prior thereto. 

              SECTION
  7.5. Confidential Information. Each Principal Geo Shareholder recognizes
  that the Company’s business interests require the fullest practical protection
  and confidential treatment of all information not generally known within the
  relevant trade group or by the public, including all documents, writings, memoranda,
  business plans, illustrations, designs, plans, processes, programs, inventions,
  computer software, reports, sources of supply, customer lists, supplier lists,
  trade secrets and all other valuable or unique information and techniques acquired,
  developed or used by Geo relating to its businesses, operations, employees and
  consultants (hereinafter collectively termed “Protected Information”).
  Each Principal Geo Shareholder expressly acknowledges and agrees that Protected
  Information constitutes trade secrets and confidential and proprietary business
  information of the Company. Protected Information shall not include information
  which is or becomes part of the public domain through no breach of this First
  Amendment by any Principal Geo Shareholder. Each Principal Geo Shareholder acknowledges
  that Protected Information is essential to the success of the Business, and
  it is the policy of the Company to maintain as secret and confidential Protected
  Information which gives the Company a competitive advantage over those who do
  not know the Protected Information and is expressly and implicitly protected
  by the Company from unauthorized disclosure. Accordingly, each Principal Geo
  Shareholder agrees to hold such Protected Information in a fiduciary capacity,
  to keep secret and to treat confidentially and not to, and not to permit any
  other Person to, directly or indirectly, appropriate, divulge, disclose or otherwise
  disseminate to any other Person nor use in any manner for any Principal Geo
  Shareholder or any other Person’s purposes or benefit any Protected Information,
  and not to use or aid others in using any such Protected Information in competition
  with the Company or its Affiliates except to the extent that disclosure is required
  by law; provided, however, that each Principal Geo Shareholder shall provide
  the Company with notice as far in advance of any required disclosure as is practicable
  in order for the Company to obtain an order or other assurance that any information
  required to be disclosed will be treated as Protected Information and each Principal
  Geo Shareholder shall use all reasonable efforts to cooperate with the Company
  in connection therewith and in 

- 24 -

furtherance thereof. This obligation of non-disclosure of information
  shall continue to exist for so long as such information remains Protected Information.

              SECTION
  7.6. Scope. If, at the time of enforcement of this Article VII, a court
  shall hold that the duration, scope or area restrictions stated herein are unreasonable
  under circumstances then existing, the parties agree that the maximum duration,
  scope or area reasonable under such circumstances shall be substituted for the
  stated duration, scope or area.

              SECTION
  7.7. Remedies. Each Principal Geo Shareholder agrees that if he, she
  or it shall commit or threaten to commit a breach of any of the covenants contained
  in this Article VII, then the Company shall have the right to obtain all appropriate
  injunctive and other equitable remedies therefor, in addition to any other rights
  and remedies that may be available at law, it being acknowledged and agreed
  that any such breach would cause irreparable injury to the Company and that
  money damages would not provide an adequate remedy therefor.

              SECTION
  10.1. Termination. This First Amendment may be terminated and the Merger
  contemplated hereby may be abandoned at any time prior to the Effective Time:

             
  (a)   by mutual consent of Geo and the Company;

             
  (b)   by either Geo or the Company:

                          
  (i)   if there shall have been a material breach of any representation,
  warranty, covenant or agreement on the part of the Company and Sub on the one
  hand, or Geo or any of the Principal Geo Shareholders on the other, set forth
  in this First Amendment which breach shall not have been cured without material
  cost to the breaching party, in the case of a representation or warranty, prior
  to the date on which the conditions other than the accuracy of the representation
  and warranty in question would be satisfied for the Closing or, in the case
  of a covenant or agreement, within five business days following receipt by the
  breaching party of notice of such breach;

                          
  (ii)   if a Governmental Authority shall have issued an order,
  decree or ruling or taken any other action, in each case permanently restraining,
  enjoining or otherwise prohibiting the transactions contemplated by this First
  Amendment, and such order, decree, ruling or other action shall have become
  final and nonappealable; or

                          
  (iii)   if the Effective Time shall not have occurred on or before
  December 31, 2003;

 provided, however, that the right to terminate
  this First Amendment shall not be available to any party whose breach of this
  First Amendment has been the cause of, or resulted in, the failure of the Merger
  to occur on or before such date.

              SECTION
  10.2. Procedure and Effect of Termination. In the event of termination
  of this First Amendment pursuant to Section 10.1 hereof, written notice thereof
  shall forthwith be given to the other parties to this First Amendment and this
  First Amendment shall terminate and the Merger shall be abandoned, without further
  action by any of the parties hereto. If this First Amendment is terminated as
  provided herein, no party hereto shall have any liability or further obligation
  to any other party to this First Amendment resulting from such termination except
  (i) that the provisions of this Section 10.2, and the proviso of Section 10.1(b)(iii)
  shall remain in full force and effect, and (ii) no party waives any claim or
  right against a breaching party to the extent that such termination results
  from the breach by a party

- 28 -

 hereto of any of its representations, warranties, covenants
  or agreements set forth in this First Amendment. The parties hereby acknowledge
  and agree that if Geo and the Principal Geo Shareholders, on the one hand, or
  the Company and Sub, on the other, are unable to provide the certificates required
  by Section 8.2(a) or 8.3(a), as applicable, because the representations and
  warranties of such parties contained in this First Amendment are not true and
  correct as of the Effective Time due to circumstances beyond the control of
  such parties discovered after the date hereof and prior to the Effective Time
  (an “Intervening Event”), and such Intervening Event did not
  constitute a breach of such parties’ representations and warranties made
  in this First Amendment on the date hereof, then the other set of parties may
  either (i) refuse to close the transaction for failure to satisfy the closing
  condition set forth in Section 8.2(a) or 8.3(a), as applicable, or close the
  transaction notwithstanding such failure, in which event no breach of a representation
  or warranty shall be deemed to have occurred as a result of the Intervening
  Event. If Geo and the Principal Geo Shareholders, on the one hand, or the Company
  and Sub, on the other, are unable to provide the certificates required by Section
  8.2(a) or 8.3(a), as applicable, because the representations and warranties
  of such parties contained in this First Amendment are not true and correct as
  of the Effective Time due to an Intervening Event, and such Intervening Event
  constituted a breach of such parties’ representations and warranties made
  in this First Amendment on the date hereof, then the other set of parties may
  either (i) refuse to close the transaction for failure to satisfy the closing
  condition set forth in Section 8.2(a) or 8.3(a), as applicable, and seek recourse
  pursuant to Section 11 of this First Amendment, as applicable, or (ii) close
  the transaction notwithstanding such failure and seek recourse pursuant to Section
  11 of this First Amendment, as applicable. 

ARTICLE XI

SURVIVAL AND INDEMNIFICATION

              SECTION
  11.1. Survival and Remedies. All representations and warranties of each
  of the parties hereto contained in this First Amendment or the Additional Agreements,
  including all statements contained in any certificate, schedule, document or
  other writing delivered pursuant hereto or in connection with the transactions
  contemplated hereby, shall be deemed to be representations and warranties within
  the meaning of this Section 11.1, shall be deemed to be material and to have
  been relied upon by the Company or the Principal Geo Shareholders, as the case
  may be, and shall survive the Closing. All of the covenants and agreements of
  each of the parties hereto contained in this First Amendment or in any document
  delivered pursuant to this First Amendment shall survive the Closing, and claims
  for indemnification relating to a breach of any such covenant or agreement may
  be made at any time. In the event of a breach of any of such representations,
  warranties, covenants and agreements, the party to whom such representation,
  warranty, covenant or agreement has been made shall have all rights and remedies
  for such breach available to it under the provisions of this First Amendment,
  or otherwise, whether of law or in equity, regardless of any disclosure to,
  or investigation made by or on behalf of such party on or before the Closing
  Date. The rights and remedies of any party based upon, arising out of or otherwise
  in respect of any inaccuracy in or breach of any representation, warranty, covenant
  or agreement contained in this First Amendment or any Additional Agreement shall
  in no way be limited by the fact that the act, omission, occurrence or other
  state of facts upon which any claim of any such inaccuracy or breach is based
  may also be the subject matter of any other representation, warranty, covenant
  or agreement contained in this First Amendment or any Additional Agreement as
  to which there is no inaccuracy or breach. 

              SECTION
  11.2. Indemnification of the Company by Geo and the Principal Geo Shareholders.
  Geo and the Principal Geo Shareholders shall, to the extent not covered and
  promptly paid by applicable insurance, jointly and severally indemnify, defend
  and hold harmless, the Company and its past, present 

- 29 -

 and future directors, officers, employees, agents, subsidiaries
  and Affiliates (the “Company Indemnified Parties”) for any
  and all loss, damage, expense (including court costs, amounts paid in settlement,
  judgments, attorneys’ fees and other expenses for investigating and defending),
  claim, deficiency, Liability or obligation related to, resulting from, caused
  by or arising from (a) any inaccuracy in or breach of any representation or
  warranty made by Geo or any of the Principal Geo Shareholders in this First
  Amendment (excluding Article IV hereof) or made by Geo or the Principal Geo
  Shareholders in any other agreement, instrument or document or information delivered
  or provided by Geo pursuant hereto or provided by Geo or the Principal Geo Shareholders
  to the Company for use by the Company in connection with any disclosure document,
  including, without limitation, the Merger Materials, the Information Circular
  and materials distributed by the Company in connection with the Private Placement,
  (b) any and all claims made in good faith based upon facts alleged that, if
  true, would have constituted any such inaccuracy or breach under subsection
  (a) above, (c) any failure to perform or breach by Geo prior to the Effective
  Time of any covenant or agreement made by Geo herein or in any other agreement,
  instrument or document delivered by Geo or any of their respective Affiliates
  pursuant hereto, and (d) any and all claims made in good faith based upon facts
  alleged that, if true, would have constituted any such breach or failure under
  subsection (c) above (collectively, the “Damages”). The foregoing
  in no way shall limit any remedy provided for herein or at law or equity resulting
  from a breach of any obligation under Article VII hereunder. 

              SECTION
  11.3. Indemnification of the Company by the Principal Geo Shareholders.
  Each Principal Geo Shareholder shall, to the extent not covered and promptly
  paid by applicable insurance, severally but not jointly, indemnify, defend and
  hold harmless the Company Indemnified Parties for any and all loss damage, expense
  (including court costs, amounts paid in settlement, judgments, attorneys’
  fees and other expenses for investigating and defending), Claim, deficiency,
  Liability or obligation related to, resulting from, caused by or arising from
  (a) any inaccuracy in or breach of any representation or warranty made by such
  Principal Geo Shareholder in Article IV herein or in any other agreement, instrument
  or document delivered by such Principal Geo Shareholder pursuant to Article
  IV herein, and (b) any and all claims made in good faith based upon facts alleged
  that, if true, would have constituted any such inaccuracy or breach under subsection
  (a) above, (c) any failure to perform or breach by such Principal Geo Shareholder
  of any covenant or agreement made by such Principal Geo Shareholder herein or
  in any other agreement, instrument or document delivered by such Principal Geo
  Shareholder or any of his, her or its Affiliates pursuant hereto, and (d) any
  and all claims made in good faith based upon facts alleged, that if true, would
  have constituted any such breach or failure under subsection (c) above. 

              SECTION
  11.4. Indemnification Procedure for Third Party Claims. 

              (a)
  If subsequent to the Effective Time any Company Indemnified Party asserts a
  claim for indemnification or receives notice of the assertion of any claim or
  of the commencement of any action or proceeding by any entity which is not a
  party to this First Amendment (including any Governmental Authority) (a “Third
  Party Claim”) against such Company Indemnified Party, with respect
  to which the Company or the Principal Geo Shareholders (“Indemnifying
  Party”) are required to provide indemnification under this First Amendment,
  the Company Indemnified Party shall give written notice together with a statement
  of any available information regarding such claim (the “Notice of Claim”)
  to the Indemnifying Party promptly after learning of such claim; provided,
  however, that notice to the Principal Geo Shareholders in accordance
  with Section 12.6 hereof shall be deemed notice to all of the Principal Geo
  Shareholders. The Company Indemnified Party shall have the right to conduct
  such defense, at the Indemnifying Party’s expense, in good faith with counsel
  reasonably acceptable to the Indemnifying Party, but the Company Indemnified
  Party shall be prohibited from compromising or settling the claim without the
  prior written consent of the Indemnifying Party, which consent shall not be

- 30 -

 unreasonably withheld or delayed. The Indemnifying Party will,
  at its expense, make available to the Company Indemnified Party such assistance
  and materials as the Company Indemnified Party may reasonably request. 

              (c)
  The Indemnified Party will cooperate with and make available to the Company
  Indemnifying Party such assistance and materials as it may reasonably request,
  all at the expense of the Indemnifying Party. The Indemnifying Party shall have
  the right at its expense to participate in the defense assisted by counsel of
  its own choosing. If the Indemnifying Party does not cooperate with and make
  available to the Company Indemnified Party such assistance and materials as
  the Company Indemnified Party shall request, then (a) the Company Indemnified
  Party shall have the right, but not the obligation, to undertake at the expense
  of the Indemnifying Party the defense or settlement of such Third Party Claim
  for the account and at the risk of the Indemnifying Party without the prior
  written consent of the Indemnifying Party, and (b) the Indemnifying Party shall
  be bound by any defense or settlement that the Indemnified Party may make as
  to such Third Party Claim. 

              (d)
  Any judgment entered or settlement agreed upon in the manner provided herein
  shall be binding upon the Indemnifying Party, and shall be conclusively deemed
  to be an obligation with respect to which the Company Indemnified Party is entitled
  to prompt indemnification hereunder, subject to the Indemnifying Party’s
  right to appeal an appealable judgment or order. 

              SECTION
  11.4 Failure to Give Timely Notice. A failure by a Company Indemnified
  Party to give timely, complete or accurate notice as provided in this Article
  XI will not affect the rights or obligations of any party hereunder except and
  only to the extent that, as a result of such failure, any party entitled to
  receive such was actually damaged as a result of such failure to give timely
  notice. 

              SECTION
  11.5. Insurance. If an Indemnified Party both collects proceeds from
  any insurance company and receives a payment from the Indemnifying Party hereunder,
  and the sum of such proceeds and payment is in excess of the Damages or losses
  with respect to the matter that is the subject of the indemnity, then the Indemnified
  Party shall promptly refund to the Indemnifying Party the amount of such excess.

ARTICLE XII

  Power Inc., an Idaho corporation, and U. S. Geothermal, Inc., an Idaho corporation,
  are the constituent corporations of a merger; U. S. Geothermal, Inc., an Idaho

  Plan of Merger has been approved, adopted and executed by each of the constituent
  corporations in accordan ce with Idaho Code §30-1-1101.

 SCHEDULE 3.24  

 Agreements 

 1.           The
  Vulcan Property  

 On March 5, 2002, Geo entered into a letter agreement with
  Vulcan, pursuant to which Geo agreed to acquire from Vulcan all of the real
  property, personal property and permits that comprised Vulcan’s interest
  in the Raft River Project. On December 3, 2002, the letter agreement was replaced
  by the Vulcan Agreement which provides for the acquisition of 100% interest
  in the Vulcan Property by Geo on the following basis: 

	1.	To earn a 20% interest in the Vulcan
        Property, Geo must pay to or for the benefit of Vulcan US$250,000. As
        at December 31, 2002, this amount has been paid and Geo has acquired the
        20% interest.

	 	 
	2.	The issue to Vulcan of 1,895,000 Geo
        Shares and 1,612,000 Geo Warrants. These securities have been issued.

	 	 
	3.	Geo must cause a publicly traded company
        to acquire all of the Geo Shares and Geo Warrants, including those issued
        to Vulcan, in exchange for securities of the public company which will
        result in Vulcan owning 14% of the issued shares and, through the exercise
        of warrants, having the right to acquire, an additional 11% of the shares
        for a total of 25% of the fully diluted issued and outstanding shares
        of the public company as of the date of acquisition of the Geo Shares
        and Geo Warrants by the publicly traded company.

       The completion of the Acquisition and Consolidation
        will satisfy this requirement. Upon completion of the Proposed Transactions
        Vulcan will hold 1,755,156 Consolidated USC Shares (approximately 11%
        of the outstanding Consolidated USC Shares) and 2,420,217 Exchange Warrants,
        which if exercised, would result in Vulcan owing 25% of the common stock
        of the Resulting Issuer. The securities to be issued to Vulcan will be
        subject to escrow. See “The Resulting Issuer - Securities of the
        Resulting Issuer held in Escrow, in Pool or Subject to Hold Restrictions”.

	 	 
	4.	Geo must complete a US$200,000 work
        program on the Vulcan Property within 12 months of the Closing.

	 	 
	5.	Geo was to pay to Vulcan US$100,000 on
        the Closing. As at April 28, 2003, $50,000 has been paid and Geo will
        pay the balance of $50,000 on Closing.

       Once all of the foregoing have been satisfied, Geo will
        own a 49% interest in the Vulcan Property.

	 	 
	6.	In order to acquire the remaining 51%
        of the Vulcan Property, Geo must pay to Vulcan US$250,000 on or before
        receipt of project financing for completion of a power plant.

All of the issued and outstanding Geo Shares as at March 5,
  2002, other than those held by Vulcan, have been pledged to Vulcan as security
  for Geo’s obligations to Vulcan under the Vulcan Agreement. The pledge
  will be released on Closing.

 - 64 - 

 Prior to entering into the Vulcan Agreement Vulcan was at
  arm’s length to Geo. The consideration payable to Vulcan under the Vulcan
  Agreement was determined through arm’s length negotiations. 

 Under the Vulcan Agreement, Geo has agreed to acquire 100%
  of the 560 acres of fee land comprising the Vulcan Property. The Vulcan Property
  includes both surface and geothermal rights and consists of two units. The first
  unit has a total area of 240 acres and is comprised of the E half of the SE
  quarter of Section 22, plus the SW quarter of Section 23 (Township 15 South,
  Range 26 East). Three geothermal wells (RRGE-1, RRGP-4 and RRGP-5) are located
  on this parcel. The second unit has a total area of 320 acres, and is comprised
  of the S half of the NW quarter, the S half of the NE quarter, and the entire
  SE quarter of Section 25 (Township 15 South, Range 26 East). Three additional
  geothermal wells (RRGE-3, RRGI-6 and RRGI-7) are located on this parcel. 

 As the Vulcan Property is fee land that would be owned by
  the project developer, there is no royalty burden. A preliminary title report
  was prepared in March 2002 for the Vulcan Property by Land Title and Escrow,
  Inc. of Burley, Idaho, which includes a Commitment For Title Insurance from
  the Commonwealth Land Title Insurance Company. 

 2.           Crank
  Lease  

 The Crank Lease covers 160 acres of geothermal rights, with
  right of ingress and egress. The lease is comprised of the NE quarter of Section
  23 (Township 15 South, Range 26 East) and includes the use of an existing geothermal
  well RRGE-2. The lease has a primary term of 5 years and is extended indefinitely
  so long as production from the well or from the geothermal field is maintained.
  Geo does not control access to the surface lands related to the Crank Lease
  except for ingress and egress for removal of the geothermal resource. Advanced
  production royalties are payable as follows: 

	• 	On signing: US$5,000 (paid)
		 
	• 	Year 2: US$10,000
		 
	• 	Year 3: US$10,000
		 
	• 	Year 4: US$15,000
		 
	• 	Year 5: US$15,000

 The advanced production royalties can be credited toward production
  royalties owed. During commercial production, there is a minimum annual production
  royalty of US$18,000. 

 Janice Crank is at arm’s length to Geo. The consideration
  payable by Geo under the Crank Lease was determined through arm’s length
  negotiation. 

 - 65 - 

 3.           Jensen
  Lease  

 The Jensen Lease covers 2,954.75 acres of geothermal rights
  only. It is contiguous with the Vulcan Property and the Crank Lease with land
  parcels located in Sections 24, 25, 26, 27, 33, and 34 (Township 15 South, Range
  26 East), and in Sections 18, 19, 20, 29, and 30 (Township 15 South, Range 27
  East). Geo does not control surface access to all lands covered by the Jensen
  Lease. 

 The lease has a primary term of 10 years and is extended indefinitely
  so long as production from the geothermal field is maintained. Lease payments
  are as follows: 

	• 	Years 1-5: US$2.50 per acre (Year 1 paid on signing)
	 	 
	• 	Years 6-10: US$3.00 per acre

Sergene Jensen is at arm’s length to Geo. The consideration
  payable by Geo under the Jensen Lease was determined through arm’s length
  negotiation. 

 4.           Jensen
  Investments Lease  

 The Jensen Investments Lease covers 44.5 acres of surface
  and geothermal rights in Section 35, Township 15 South, Range 26 East, and is
  contiguous with the Jensen Lease. The lease has a primary term of 10 years and
  is extended indefinitely so long as production from the geothermal field is
  maintained. Lease payments are as follows: 

	• 	Years 1-5: US$2.50 per acre (Year 1 paid on signing)
	 	 
	• 	Years 6-10: US$3.00 per acre

The three leased parcels, (Crank Lease, Jensen Lease and Jensen
  Investments Lease) have production royalties payable under the following terms:

	(a)	Energy produced, saved and used for
        the generation of electric power, which is then sold by lessee, has a
        royalty of ten percent (10%) of the net proceeds.

	 	 
	(b)	Energy produced, saved and sold by lessee,
        then used by the purchaser for generation of electric power, has a royalty
        of ten percent (10%) of the market value.

	 	 
	(c)	Energy produced, which is used for any
        purpose other than the generation of electricity has a royalty of five
        percent (5%) of the gross proceeds.

 Jensen Investments Inc. is at arm’s length to Geo. The
  consideration payable by Geo under the Jensen Investment Lease was determined
  through arm’s length negotiation. 

 Geo has not determined whether any wetlands exist on these
  properties nor whether any of the properties are in a flood plain. All buildings,
  infrastructure, and geothermal wells located on the properties are offered in
  an “as is” condition and no warranty or representation is made as
  to their ultimate use. 

 Additional lease agreements are under negotiation with Reid
  Stewart.
