U.S. GEOTHERMAL INC.
INCORPORATED UNDER THE LAWS OF DELAWARE

On the terms hereof, this is to certify that FOR VALUE RECEIVED, [Agent], [Address], the registered holder hereof (the "Holder"), has the right to purchase at any time and from time to time, up to and including 5:00 p.m. (Toronto time) on August 17, 2011 (the "Expiry Time"), z fully paid and non-assessable common shares (the "Common Shares") without par value in the capital of U.S. Geothermal Inc.

The Company agrees that the Common Shares so purchased shall be and be deemed to be issued to the Holder as of the close of business on the date on which this Compensation Option Certificate shall have been surrendered and payment made for such shares as aforesaid.

Nothing contained herein shall confer any right upon the Holder to subscribe for or purchase any Common Shares of the Company at any time after the Expiry Time, and from and after the Expiry Time, this Compensation Option and all rights hereunder shall be void and of no value.

The above provisions are, however, subject to the following:

SECTION 1. - In the event the Holder desires to exercise the right conferred hereby to purchase Common Shares in the capital of the Company, the Holder shall at or before the Expiry Time: (a) duly complete, execute and deliver to the Company a Subscription Form for such Common Shares in the form annexed hereto, together with any additional documentation required thereby, (b) surrender this Compensation Option Certificate to the Company at the address of the Company indicated in Section 16 hereof, and (c) pay the aggregate Exercise Price in respect of the Common Shares in the capital of the Company subscribed for either in cash, by bank draft or by certified cheque drawn on a Canadian chartered bank and payable to the Company. Upon such delivery, surrender and payment as aforesaid and subject to the provisions hereof, the Holder shall be deemed for all purposes to be a shareholder of record of the number of Common Shares in the capital of the Company to be so issued and the Holder shall be entitled to delivery of a certificate or certificates evidencing such Common Shares (which certificates, as well as all certificates issued in exchange for or in substitution thereof, shall bear any applicable restrictive legends) and the Company shall cause such certificate or certificates to be delivered to the Holder at the address specified in said Subscription Form within ten days of said surrender and payment as aforesaid.

For purposes of complying with the United States Securities Act of 1933, as amended (the "U.S. Securities Act") and applicable U.S. state securities laws, the Holder understands and acknowledges that upon the issuance of the Common Shares issuable hereunder, all the certificates representing the Common Shares, as well as all certificates issued in exchange for or in substitution of the foregoing securities, shall bear the following additional legends:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "U.S. SECURITIES ACT") OR ANY STATE SECURITIES LAWS. THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT OF THE COMPANY THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY: (A) TO THE COMPANY, (B) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE U.S. SECURITIES ACT, (C) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT IF AVAILABLE, (D) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE U.S. SECURITIES ACT PROVIDED BY RULE 144, IF AVAILABLE, AND IN COMPLIANCE WITH ANY STATE SECURITIES LAWS, OR (E) WITH THE PRIOR WRITTEN CONSENT OF THE COMPANY, PURSUANT TO ANOTHER EXEMPTION FROM REGISTRATION UNDER THE U.S. SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS; PROVIDED THAT, IN CONNECTION WITH A TRANSFER PURSUANT TO (C), (D) OR (E) ABOVE, AN OPINION OF COUNSEL, OF RECOGNIZED STANDING REASONABLY SATISFACTORY TO THE CORPORATION HAS BEEN PROVIDED TO THE COMPANY TO SUCH EFFECT.

- - 2 -

and provided further, that, if any of the Common Shares issuable hereunder are being sold pursuant to Rule 144 of the U.S. Securities Act, the legend may be removed by delivering to the Company and to the Company's transfer agent an opinion of counsel of recognized standing in form and substance satisfactory to the Company to the effect that the legend is no longer required under applicable requirements of the U.S. Securities Act or state securities laws.

This Compensation Option may not be exercised unless an exemption from registration is available under the U.S. Securities Act and any applicable state securities laws and the Company has received an opinion of counsel of recognized standing in form and substance reasonably satisfactory to the Company or other evidence reasonably satisfactory to the Company to such effect; provided that an institutional "accredited investor" that satisfies the criteria set forth in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the U.S. Securities Act that is the original purchaser of this Compensation Option will not be required to deliver an opinion of counsel in connection with the exercise of these Compensation Options.

SECTION 2. - The right to purchase Common Shares in the capital of the Company conferred hereby may be exercised in whole or in part. In the event that prior to the Expiry Time the Holder subscribes for and purchases any number of Common Shares which is less than the number of shares referred to in this Compensation Option Certificate, the Holder shall present the original of this Compensation Option Certificate to the Company and the Holder will be entitled to receive a further Compensation Option Certificate in respect of the Common Shares referred to in this Compensation Option Certificate but not subscribed for.

SECTION 3. – The Compensation Options represented hereby are not transferable.

SECTION 4. - This Compensation Option Certificate may be exchanged for Compensation Option Certificates in any other denomination representing in the aggregate the same number of underlying Common Shares. The Holder may exercise this right by surrendering this Compensation Option Certificate, together with a written direction, to the Company at the address of the Company indicated in Section 16 below and the Company shall cause the new Compensation Option Certificates to be delivered to the Holder at the address specified in such direction within ten days of said surrender as aforesaid.

SECTION 5. - In case this Compensation Option Certificate shall become mutilated or be lost, destroyed or stolen, the Company shall, upon the Holder complying with this Section 5, issue and deliver a new Compensation Option Certificate of like date and tenor in exchange for and in place of the one mutilated, lost, destroyed or stolen and upon surrender and cancellation of such mutilated Compensation Option Certificate or in substitution for such lost, destroyed or stolen Compensation Option Certificate. The applicant for the issue of a new Compensation Option Certificate pursuant to this Section 5 shall bear the cost of the issue thereof and in case of loss, destruction or theft shall, as a condition precedent to the issue thereof, furnish to the Company such evidence of ownership and of the loss, destruction or theft of the Compensation Option Certificate so lost, destroyed or stolen as shall be reasonably satisfactory to the Company and such applicant may be required to furnish an indemnity in amount and form satisfactory to the Company.

SECTION 6. - The holding of the Compensation Options shall not constitute the Holder a shareholder of the Company nor entitle the Holder to any right or interest in respect thereof except as herein expressly provided.

- - 3 -

SECTION 7. - The Company represents and warrants that:

The Company covenants and agrees that it will cause the Common Shares subscribed for and purchased in the manner herein provided and the certificate or certificates evidencing such Common Shares to be duly issued and that, at all times prior to the Expiry Time, it shall reserve and there shall remain unissued out of its authorized capital a sufficient number of shares to satisfy the right of purchase herein provided for. All Common Shares which shall be issued upon the exercise of the right of purchase herein provided for, upon payment therefor of the aggregate Exercise Price for such Common Shares, shall be and be deemed to be fully paid and non-assessable and the Holder shall not be liable to the Company or its creditors in respect thereof.

SECTION 8. - In Section 8 and Section 9:

"Equity Shares" means the Common Shares and any shares of any class or series of the Company which may from time to time be authorized for issue if by their terms such shares confer on the holders thereof the right to participate in the distribution of assets upon the voluntary or involuntary liquidation, dissolution, or winding-up of the Company beyond a fixed sum or a fixed sum plus accrued dividends; and

"Current Market Price" of the Common Shares at any date means the weighted average price per share at which the Common Shares have traded on the NYSE-Amex, or such other exchange on which the Common Shares are listed and which has the highest trading volume of Common Shares on that date, during any 20 consecutive trading days ending not more than 5 days immediately preceding such date. In the event the Common Shares are not listed on any stock exchange, the Current Market Price of the Common Shares shall be determined by the directors acting reasonably and in good faith.

- - 4 -

If at any time from August 17, 2009 and prior to the Expiry Time and while this Compensation Option Certificate is outstanding there shall be a reclassification of the Common Shares outstanding at any time or a change of the Common Shares into other shares or securities, or any other capital reorganization except as described in Section 9, or a consolidation, amalgamation or merger of the Company with or into any other corporation (other than a consolidation, amalgamation or merger which does not result in any reclassification of the outstanding Common Shares or a change of the Common Shares into other shares or securities), or a transfer of the undertaking or assets of the Company as an entirety or substantially as an entirety to another corporation or other entity (any of such events being called a "Capital Reorganization"), should the Holder exercise thereafter its right to purchase Common Shares hereunder, the Holder shall be entitled to receive, and shall accept for the same aggregate consideration, in lieu of the number of Common Shares to which it was theretofore entitled upon the exercise of the right to purchase Common Shares hereunder, the kind and amount of shares or other securities or property which the Holder would have been entitled to receive as a result of such Capital Reorganization if, on the effective date thereof, it had been the registered holder of the number of Common Shares to which it was theretofore entitled upon such exercise.

If at any time from August 17, 2009 and prior to the Expiry Time and while this Compensation Option Certificate is outstanding any adjustment in the Exercise Price shall occur as a result of:

SECTION 9. - The Exercise Price in effect at any date shall be subject to adjustment from time to time as follows:

(a)

If and whenever at any time from August 17, 2009 and prior to the Expiry Time and while this Compensation Option Certificate is outstanding, the Company shall:

(any of such events being called a "Common Share Reorganization"), the Exercise Price shall be adjusted effective after the effective date or record date, as the case may be, on which the holders of Common Shares are determined for the purpose of the Common Share Reorganization by multiplying the Exercise Price in effect immediately prior to such effective date or record date by a fraction, the numerator of which shall be the number of Common Shares of the Company outstanding on such effective date or record date before giving effect to such Common Share Reorganization and the denominator of which shall be the number of Common Shares outstanding immediately after giving effect to such Common Share Reorganization including, in the case where securities exchangeable for or convertible into Common Shares are distributed, the number of Common Shares that would have been outstanding had all such securities been exchanged for or converted into Common Shares on such record date. For purposes of this Subsection 9(a), "dividend in the ordinary course" means dividends having a value which does not exceed, in the aggregate, the greater of (i) 50% of the retained earnings of the Company as at the end of its immediately preceding fiscal year; and (ii) 100% of the aggregate consolidated net income of the Company determined before computation of extraordinary or unusual items, for its immediately preceding fiscal year.

- - 5 -

(b)

If and whenever at any time from August 17, 2009 and prior to the Expiry Time and while this Compensation Option Certificate is outstanding, the Company shall fix a record date for the issue of rights, options or warrants to the holders of all or substantially all of its outstanding Common Shares under which such holders are entitled, during a period expiring not more than ninety days after the record date for such issue, to subscribe for or purchase Common Shares at a price per Common Share or having a conversion or exchange price per Common Share less than 95% of the Current Market Price per Common Share on such record date, the Exercise Price shall be adjusted immediately after such record date so that it shall equal the price determined by multiplying the Exercise Price in effect on such record date by a fraction, the numerator of which shall be the total number of Common Shares outstanding on such record date plus a number equal to the number arrived at by dividing the aggregate price of the total number of additional Common Shares offered for subscription or purchase, or the aggregate conversion or exchange price of the convertible securities so offered, by such Current Market Price per Common Share, and of which the denominator shall be the total number of Common Shares outstanding on such record date plus the total number of additional Common Shares offered for subscription or purchase (or into which the convertible securities so offered are convertible or exchangeable). Any Common Shares owned by or held for the account of the Company or any subsidiary of the Company shall be deemed not to be outstanding for the purpose of any such computation. To the extent that any adjustment in the Exercise Price occurs pursuant to this Subsection 9(b) as a result of the fixing by the Company of a record date for the distribution of rights, options or warrants referred to in this Subsection 9(b), the Exercise Price shall be readjusted immediately after the expiration of any relevant exchange, conversion or exercise right to the Exercise Price which would then be in effect based upon the number of Common Shares actually issued and remaining issuable after such expiration, and shall be further readjusted in such manner upon expiration of any further such right.

SECTION 10. - In any case in which it shall be required that an adjustment shall become effective immediately after a record date for an event referred to herein, the Company may defer, until the occurrence of such event,

- - 6 -

 The adjustments provided for herein are cumulative; shall, in the case of adjustments to the Exercise Price, be computed to the nearest one-tenth of one cent; and shall apply (without duplication) to successive subdivisions, consolidations, distributions, issuances or other events resulting in any adjustment under the provisions hereof provided that, notwithstanding any other provision hereof, no adjustment of the Exercise Price shall be required unless such adjustment would require an increase or decrease of at least 1% in the Exercise Price then in effect and no adjustment shall be made in the number of Common Shares purchasable on the exercise of the Compensation Options unless it would result in a change of at least one-hundredth of a share (provided, however, that any adjustments which by reason of this Section 10 are not required to be made shall be carried forward and taken into account in any subsequent adjustment).

In the event of any question arising with respect to the adjustments provided for herein such question shall be conclusively determined by a firm of chartered accountants (who may be the Company's auditors) appointed by the Company; such accountants shall have access to all necessary records of the Company and such determination shall, in the absence of manifest error, be binding upon the Company and the Holder.

In case the Company after the date of this Compensation Option Certificate shall take any action affecting the Common Shares, other than an action described herein, which in the opinion of the directors of the Company would materially affect the rights of the Holder, the Exercise Price and/or the number of Common Shares purchasable upon exercise of the Compensation Options shall be adjusted, subject to the prior written consent of the Toronto Stock Exchange, if required, in such manner, if any, and at such time, by action by the directors, in their discretion as they may determine to be equitable in the circumstances. Failure of the directors to make an adjustment in accordance with this Section 10 shall be conclusive evidence that the directors have determined that it is equitable to make no adjustment in the circumstances.

If the Company shall set a record date to determine the holders of the Common Shares for the purpose of entitling them to receive any issue or distribution or for the issue of any rights, options or warrants and shall thereafter and before such distribution or issue to such shareholders legally abandon its plan to make such distribution or issue, then no adjustment in the Exercise Price or the number of Common Shares purchasable upon exercise of the Compensation Options shall be required by reason of the setting of such record date.

In the absence of a resolution of the directors fixing a record date for any of the events referred to in Subsection 9(b), the Company shall be deemed to have fixed as the record date therefor the date on which any of such events is effected.

SECTION 11. - As a condition precedent to the taking of any action which would require an adjustment pursuant to Sections 8 or 9, the Company shall take any action which may, in the opinion of counsel, be necessary in order that the Company may validly and legally issue as fully paid and non-assessable all the Common Shares to which Holder is entitled to receive on the full exercise hereof in accordance with the provisions hereof.

SECTION 12. - At least ten days prior to the effective date or record date, as the case may be, of any event which, if implemented, will require an adjustment in any of the subscription rights pursuant to this Compensation Option Certificate, including the Exercise Price and the number of Common Shares which are purchasable upon the exercise hereof, the Company shall give notice to the Holder of the particulars of such event and, if determinable and applicable, the required or anticipated adjustment and the computation of such adjustment.

- - 7 -

In case any adjustment for which a notice in this Section 12 has been given is not then determinable, the Company shall promptly after such adjustment is determinable give notice to the Holder of the adjustment and the computation of such adjustment.

SECTION 13. - The Company covenants and agrees that at the expense of the Holder, it will do, acknowledge and deliver, or cause to be done, executed, acknowledged and delivered, all such other acts, deeds and assurances as the Holder shall reasonably require for the better accomplishing and completion of the intentions and provisions of this Compensation Option Certificate.

SECTION 14. - Time shall be of the essence hereof.

SECTION 15. – This Compensation Option Certificate, any amendment, addendum, exhibit, supplement or other document relating hereto, and any and all disputes arising herefrom or related hereto, shall be governed by and construed in accordance with the internal laws of the Province of British Columbia, and the federal laws of Canada applicable therein, governing disputes occurring, and contracts made and to be performed, wholly therein, and without reference to its principles governing the choice or conflict of laws. The parties hereto irrevocably attorn and submit to the exclusive jurisdiction of the courts of the Province of Ontario, sitting in the City of Toronto, with respect to any dispute related to or arising from this Agreement.

SECTION 16. - Any notice required or permitted to be given hereunder shall be in writing and may be given by delivery or by facsimile transmission of same addressed as follow:
