The Company has authorized the sale and issuance to certain
investors of up to an aggregate of 5,000,000 units of the Company (the
“Units”), subject to adjustment by the Company’s Board of Directors, or a
committee thereof, with each Unit consisting of (i) one share of common stock of
the Company, par value US$0.001 per share (the “Common Shares”), and (ii)
one-half of one common share purchase warrant (a “Warrant” and,
collectively, the “Warrants”). Each whole Warrant will entitle the holder
to purchase one (1) Common Share at an exercise price of US$1.075 per Common
Share (subject to adjustment) and is exercisable for a period of twelve (12)
months from the Closing Date (as defined in Annex 1). The certificate
representing the Warrants shall be in substantially the form of Exhibit B

5,000,000 Common Shares so proposed to be sold is hereinafter referred to as the
“Shares.” The Units will not be issued or certificated. The Shares and
the Warrants are immediately separable and will be issued separately. The Common
Shares issuable upon exercise of the Warrants are referred to herein as the
“Warrant Shares” and, together with the Units, the Shares and the
Warrants, are referred to herein as the “Securities”).

supplements thereto is referred to herein as the “Registration
Statement”) filed by the Company with the U.S. Securities and
Exchange Commission (the “Commission”), (2) if applicable, certain “free
writing prospectuses” (as that term is defined in Rule 405 under the U.S.
Securities Act of 1933, as amended (the “Securities Act”)), that have
been or will be filed with the Commission and delivered to the Investor on or
prior to the date hereof (each, an “Issuer Free Writing Prospectus”), and
(3) a Prospectus Supplement (the “Prospectus Supplement” and together
with the Base Prospectus, the “Prospectus”) containing certain
supplemental information regarding the Units and the terms of the Offering that
has been or will be filed with the Commission and delivered to the Investor (or
made available to the Investor by the filing by the Company of an electronic
version thereof with the Commission). 

4. 

The Company and the Investor agree that the Investor will
purchase from the Company and the Company will issue and sell to the Investor
the Units set forth below for the aggregate purchase price set forth below. The
Units shall be purchased pursuant to the Terms and Conditions for Purchase of
Units attached hereto as Annex I and incorporated herein by this

expenses in respect of the sale of the Units.

agrees with, the Company and the Placement Agent that: 

4.1 

The Investor (a)
is knowledgeable, sophisticated and experienced in making, and is qualified to
make decisions with respect to, investments in securities presenting an investment decision like that involved in the purchase of the
Units, including investments in securities issued by the Company and investments
in comparable companies, and has requested, received, reviewed and considered
all information it deemed relevant in making an informed decision to purchase
the Units, (b) the Investor has answered all questions on the Investor
Questionnaire for use in preparation of the Prospectus Supplement and the
answers thereto are true and correct as of the date hereof and will be true and
correct as of the Closing Date and (c) the Investor, in connection with its
decision to purchase the number of Units set forth on the Signature Page, is
relying only upon the Disclosure Package and the documents incorporated by

been or will be taken in any jurisdiction outside the United States by the

possession or distribution of offering materials in connection with the issue of
the Shares, in any jurisdiction outside the United States where action for that
purpose is required, (b) if the Investor is outside the United States, it will
comply with all applicable laws and regulations in each foreign jurisdiction in

contemplated hereby and has taken all necessary action to authorize the
execution, delivery and performance of this Agreement, and (b) this Agreement
constitutes a valid and binding obligation of the Investor enforceable against
the Investor in accordance with its terms, except as enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting creditors’ and contracting parties’ rights generally and
except as enforceability may be subject to general principles of equity
(regardless of whether such enforceability is considered in a proceeding in
equity or at law) and except as to the enforceability of any rights to
indemnification or contribution that may be violative of the public policy
underlying any law, rule or regulation (including any federal or state
securities law, rule or regulation). 

4.4 

The Investor
understands that nothing in this Agreement, the Prospectus, the Disclosure
Package or any other materials presented to the Investor in connection with the
purchase and sale of the Units constitutes legal, tax or investment advice. The
Investor has consulted such legal, tax and investment advisors and made such
investigation as it, in its sole discretion, has deemed necessary or appropriate
in connection with its purchase of Units. The Investor also understands that
there is no established public trading market for the Warrants being offered in
the Offering, and that the Company does not expect such a market to develop. In
addition, the Company does not intend to apply for listing of the Warrants on
any securities exchange. The Investor understands that without an active market,
the liquidity of the Warrants will be limited.

information acquired as a result of the transactions contemplated hereby prior

Section 14 of this Annex.

such Investor about the Offering, the Investor has not disclosed any information
regarding the Offering to any third parties (other than its legal, accounting
and other advisors in connection with the Offering) and has not engaged in any
purchases or sales of the securities of the Company (including, without
limitation, any Short Sales (as defined herein) involving the Company’s
securities). The Investor covenants that it will not engage in any purchases or
sales of the securities of the Company (including Short Sales) prior to the time
that the transactions contemplated by this Agreement are publicly disclosed. The
Investor agrees that it will not use any of the Securities acquired pursuant to
this Agreement to cover any short position in the Common Shares if doing so
would be in violation of applicable securities laws. For purposes hereof, “Short
Sales” include, without limitation, all “short sales” as defined in Rule 200
promulgated under Regulation SHO under the Exchange Act, whether or not against
the box, and all types of direct and indirect share pledges, forward sales
contracts, options, puts, calls, short sales, swaps, “put equivalent positions”
(as defined in Rule 16a-1(h) under the Exchange Act) and similar arrangements
(including on a total return basis), and sales and other transactions through
non-U.S. broker dealers or foreign regulated brokers.

purchasing the Units for the account or benefit of a Canadian resident; (ii) was
not offered the Units in Canada, and (iii) did not execute or deliver this
Agreement in Canada.

instituted in any such jurisdiction revoking, limiting or curtailing or seeking
to revoke, limit or curtail such power and authority or qualification. 

5.2 

The Company has the requisite corporate power and
authority to enter into and to consummate the transactions contemplated by this
Agreement and otherwise to carry out its obligations hereunder. The execution
and delivery of this Agreement by the Company and the consummation by it of the
transactions contemplated hereby have been duly authorized by all necessary action on the part of the Company and no further
action is required by the Company, the Company’s Board of Directors or the
Company’s shareholders in connection therewith. This Agreement has been (or upon
delivery will have been) duly executed by the Company and, when delivered in

obligation of the Company enforceable against the Company in accordance with its
terms.

conflict with or violate any provision of the Company’s or any subsidiary’s
certificate or articles of incorporation, bylaws or other organizational or
charter documents, or (ii) result in the creation of any lien upon any of the
properties or assets of the Company or any subsidiary, or give to others any
rights of termination, amendment, acceleration or cancellation (with or without
notice, lapse of time or both) of or conflict with, or constitute a default (or
an event that with notice or lapse of time or both would become a default)
under, any agreement, credit facility, debt or other instrument (evidencing a
Company or subsidiary debt or otherwise) or other understanding to which the
Company or any subsidiary is a party or by which any property or asset of the
Company or any subsidiary is bound or affected, or (iii) conflict with or result
in a violation of any law, rule, regulation, order, judgment, injunction, decree
or other restriction of any court or governmental authority to which the Company
or a subsidiary is subject (including federal and state securities laws and
regulations), or by which any property or asset of the Company or a subsidiary
is bound or affected. 

5.4 

The Company is not required to obtain any consent,
waiver, authorization or order of, give any notice to, or make any filing or
registration with, any court or other federal, state, local or other
governmental authority or any other person or entity (including, without
limitation, any shareholder of the Company), in connection with the execution,
delivery and performance by the Company of this Agreement and the consummation
of the transactions contemplated hereby, including the sale and issuance of the
Shares to the Investor, other than the approval of the Toronto Stock Exchange
and the NYSE Amex LLC and the filing with the Commission of the Prospectus
Supplement, or such other consents or various waivers which have already been
obtained. 

5.5 

The Shares are duly authorized and, when issued and
paid for in accordance with this Agreement, will be duly and validly issued,
fully paid and non-assessable, free and clear of all liens. The Company has
reserved from its duly authorized capital the maximum number of Common Shares
issuable pursuant to this Agreement. The Registration Statement conforms with
the requirements of the Securities Act of 1933, as amended (the “Securities
Act”), including the Base Prospectus, and such amendments and supplements
thereto as may have been required as of the date of this Agreement. The
Registration Statement is effective in respect of the Shares under the
Securities Act and no stop order preventing or suspending the effectiveness of
the Registration Statement or suspending or preventing the use of the Prospectus
has been issued by the Commission and no proceedings for that purpose have been
instituted or, to the knowledge of the Company, are threatened by the
Commission. The Company has filed or will file the Prospectus Supplement with
the Commission on the date hereof. At the time the Registration Statement and
any amendments thereto became effective and at the date of this Agreement, the
Registration Statement (including documents incorporated by reference therein)
and any amendments thereto filed as of the applicable time, conformed and will
conform in all material respects to the requirements of the Securities Act and did not and will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein
not misleading; and the Prospectus (including any documents incorporated by
reference therein) and any amendments or supplements thereto, at the time the
Prospectus or any amendment or supplement thereto was issued and at the Closing
Date, conformed and will conform in all material respects to the requirements of

not misleading.

years preceding the date hereof (the foregoing materials, including the exhibits
thereto and documents incorporated by reference therein, together with the
Prospectus and any Prospectus Supplement, being collectively referred to herein
as the “SEC Reports”). The financial statements of the Company included
in the SEC Reports comply in all material respects with applicable accounting
requirements and the rules and regulations of the Commission with respect
thereto as in effect at the time of filing. Such financial statements have been
prepared in accordance with United States generally accepted accounting
principles applied on a consistent basis during the periods involved
(“GAAP”), except as may be otherwise specified in such financial
statements or the notes thereto and except to the extent that unaudited
financial statements may not contain all footnotes required by GAAP, and such
statements fairly present in all material respects the financial position of the
Company on a consolidated basis as of and for the dates thereof and the results
of operations and cash flows for the periods then ended, subject, in the case of
unaudited statements, to normal, immaterial, year-end audit adjustments.

registration. The Common Shares are listed on the Toronto Stock Exchange under
the symbol “GTH” and NYSE Amex LLC under the symbol “HTM”.

5.8 

The Company and the Company’s Board of Directors
have taken all necessary action, if any, in order to render inapplicable any
control share acquisition, business combination, poison pill (including any
distribution under a rights agreement) or other similar anti-takeover provision
under the Company’s articles of association (or similar charter documents) or
the laws of its jurisdiction of incorporation that is or could become applicable
to the Investor as a result of the transactions contemplated hereby and the
Company fulfilling their obligations or exercising their rights under this
Agreement, including, without limitation, as a result of the Company’s issuance
of the Shares and the Investor’s ownership of the Shares.

Investor is acting solely in the capacity of an arm’s length purchaser with
respect to this Agreement and the transactions contemplated hereby. The Company
further acknowledges that the Investor is not acting as a financial advisor or
fiduciary of the Company (or in any similar capacity) with respect to this Agreement and the transactions contemplated thereby and any
advice given by the Investor or any of its representatives or agents in
connection with this Agreement and the transactions contemplated thereby is
merely incidental to the Investor’s purchase of the Shares. The Company further
represents to the Investor that the Company’s decision to enter into this
Agreement has been based solely on the independent evaluation of the
transactions contemplated hereby by the Company and its representatives. 

A1-6 

5.10 

The Company has not, and to its knowledge no one
acting on its behalf has, (i) taken, directly or indirectly, any action designed

agreements of the Investor in Section 4 hereof.

U.S. GEOTHERMAL INC. 

	NO. • 	• WARRANTS 

Date of Issuance: [  ], 2011 (the “Issuance Date”)

COMMON SHARE PURCHASE WARRANTS 

THIS IS TO CERTIFY THAT for value received •, the registered
holder hereof or its permitted assigns (the “Holder”), is entitled,
subject to the terms set forth below, for each whole warrant represented by this
certificate (this “Warrant Certificate”) to purchase, at any time or
times on or after the Issuance Date up to and including 5:00 p.m. (New York
time) on [ ], 2012 (the “Time of Expiry”), one fully paid and
non-assessable common share (“Common Share”) in the capital of U.S.
Geothermal Inc. (the “Company”) (such common share, a “Warrant
Share” and collectively, the “Warrant Shares”) at a price per share
of US$1.075 (the “Exercise Price”), subject to adjustment as
hereinafter referred to. The warrants represented by this Warrant Certificate
are the warrants to purchase Common Shares (the “Warrants”) issued
pursuant to (i) that certain Subscription Agreement, dated as of [ ], 2011, by
and between the Company and the Holder (the “Subscription Agreement”) and
(ii) the Company’s Registration Statement on Form S-3 (File number 333-170202)
including the exhibits thereto, as amended at the date of this Warrant
Certificate (the “Registration Statement”), the Prospectus contained
therein filed with the Securities and Exchange Commission (the
“Commission”), effective December 1, 2010, and a Prospectus Supplement
containing certain supplemental information regarding the securities that will
be filed with the Commission. 

	1. 	Exercise of Warrants. 
	 	 
	1.1 	Election to Purchase. 

The rights evidenced by this Warrant Certificate may be
exercised by the Holder on any day on or after the Issuance Date, in whole or in
part, up to and including the Time of Expiry in accordance with the provisions
hereof. The exercise may be effected by providing to the Company at 1505 Tyrell
Lane Boise, Idaho 83706, U.S.A. (or such other address as may be notified in
writing by the Company) (i) this Warrant Certificate and a duly completed and
executed Subscription Form in substantially the form attached as Exhibit “1”
hereto (“Subscription Form”) and (ii) (A) payment of the Exercise Price
by a certified cheque, bank draft or money order payable at par to the order of
the Company, or by wire or electronic funds transfer to an account designated by
the Company, in each case in the amount of the aggregate Exercise Price for the
number of Warrant Shares specified in the Subscription Form (the “Aggregate
Exercise Price”) or (B) provided the conditions for cashless exercise set
forth in Section 1.5 are satisfied, by notifying the Company that the Warrants
are being exercised pursuant to a Cashless Exercise (as defined in Section 1.5)
.. A duly completed and executed Subscription Form shall be deemed to be
delivered only upon personal delivery thereof to, or if sent by mail or other
means of transmission upon actual receipt thereof by, the Company. If the Holder
subscribes for a lesser number of Common Shares than may be subscribed for
pursuant to this Warrant Certificate, the Holder shall be entitled to receive,
without charge to the Holder, a new warrant certificate in respect of the balance of the
Warrants referred to in any surrendered warrant certificate but not exercised
pursuant to the Subscription Form. On or before the first (1st)
business day following the date on which the Company has received each of this
Warrant Certificate, the duly executed Subscription Form and the Aggregate
Exercise Price (or notice of a Cashless Exercise) (collectively, the
“Exercise Delivery Documents”), the Company shall transmit by facsimile
or electronic mail an acknowledgment of confirmation of receipt of the Exercise
Delivery Documents to the Holder and to the Company’s transfer agent (the
“Transfer Agent”). For purposes of this Warrant Certificate, “business
day” means any day which is not Saturday or Sunday or a legal holiday in the
City of New York, New York. 

- 2 - 

	1.2 	Exercise. 

The Company shall, as soon as possible following the date of
receipt of the Exercise Delivery Documents (the “Exercise Date”) and in
accordance with Section 1.3, issue as of the Exercise Date that number of
Warrant Shares specified in the Subscription Form as fully paid and
non-assessable Common Shares in the capital of the Company. The Company shall
pay any and all transfer taxes which may be payable with respect to the issuance
and delivery of Warrant Shares upon exercise of the Warrants. 

	1.3 	Share Delivery. 

As promptly as practicable after the Exercise Date and, in any
event, within three (3) business days of the Exercise Date (the “Share
Delivery Date”), the Company shall, (i) credit such aggregate number of
Warrant Shares to which the Holder is entitled pursuant to such exercise to the
Holder’s or its designee’s balance account with The Depository Trust Company
(“DTC”) through its Deposit/Withdrawal At Custodian system, or (ii) issue
and dispatch by overnight courier to the address as specified in the
Subscription Form, or, if not so specified in the Subscription Form, cause to be
held for collection by the Holder at the address of the Company as set out in
subsection 1.1 (or at such additional place as may be decided by the Company
from time to time and notified to the Holder), certificates, registered in the
Company’s share register in the name of the Holder or its designee, for the
number of Warrant Shares to which the Holder is entitled pursuant to such
exercise. Subject to applicable laws, upon delivery of the Exercise Delivery
Documents, the Holder shall be deemed for all corporate purposes to have become
the holder of record of the Warrant Shares with respect to which the Warrants
have been exercised, irrespective of the date such Warrant Shares are credited
to the Holder’s DTC account or the date of delivery of the certificates
evidencing such Warrant Shares, as the case may be. 

	1.4 	Company’s Failure to Timely Deliver Securities.

If, upon the Company’s exercise of the Warrants, the Company
shall fail for any reason or for no reason to issue to the Holder within three
(3) trading days of receipt of the Exercise Delivery Documents in compliance
with the terms of this Section 1, a certificate for the number of Warrant
Shares to which the Holder is entitled and register such Warrant Shares on the
Company’s share register, or to credit the Holder’s balance account with DTC for
such number of Warrant Shares to which the Holder is entitled, and if on or
after such third (3rd) trading day the Holder purchases (in an open
market transaction or otherwise) Common Shares to deliver in satisfaction of a sale by the Holder of Warrant Shares issuable
upon such exercise that the Holder anticipated receiving from the Company (a
“Buy-In”), then the Company shall, within three (3) business days after
the Holder’s written request and in the Holder’s discretion, either (i) pay cash
to the Holder in an amount equal to the Holder’s total purchase price (including
brokerage commissions, if any) for the Common Shares so purchased (the
“Buy-In Price”), at which point the Company’s obligation to deliver such
certificate (and to issue such Warrant Shares) shall terminate, or (ii) promptly
honor its obligation to deliver to the Holder a certificate or certificates
representing such Warrant Shares and pay cash to the Holder in an amount equal
to the excess (if any) of the Buy-In Price over the product of (A) such number
of Common Shares, times (B) the Closing Bid Price (as defined below) on the date
of exercise. 

- 3 - 

As used in this Warrant Certificate, “Closing Bid Price”
means, for any security as of any date, the last closing bid price for such
security on the Principal Market (as defined in Section 2.1), as reported by
Bloomberg, or, if the Principal Market begins to operate on an extended hours
basis and does not designate the closing bid price, then the last bid price of
such security prior to 4:00:00 p.m., New York Time, as reported by Bloomberg,
or, if the Principal Market is not the principal securities exchange or trading
market for such security, the last closing bid price or last trade price,
respectively, of such security on the principal securities exchange or trading
market where such security is listed or traded as reported by Bloomberg, or if
the foregoing do not apply, the average of the bid prices, or the ask prices,
respectively, of any market makers for such security as reported in the “pink
sheets” by OTC Pink (formerly the National Quotation Bureau, Inc.). If the
Closing Bid Price cannot be calculated for a security on a particular date on
any of the foregoing bases, the Closing Bid Price of such security on such date
shall be the fair market value as mutually determined by the Company and the
Holder. All such determinations to be appropriately adjusted for any share
dividend, share split, share combination or other similar transaction during the
applicable calculation period.

	1.5 	Cashless Exercise Under Certain Circumstances.

Notwithstanding anything contained herein to the contrary, if,
at any time following the Issuance Date, a registration statement under the
United States Securities Act of 1933, as amended (the “U.S. Securities
Act”), including any amendments or supplements thereto, registering the
Warrant Shares (a “U.S. Registration Statement”) is not effective
thereunder, prior to the Time of Expiry, and for so long as the U.S.
Registration Statement is not effective, any holder of any Warrant must exercise
the Warrants in whole or in part on a “cashless basis” and, in lieu of making
the cash payment otherwise contemplated to be made to the Company upon such
exercise in payment of the Aggregate Exercise Price, receive upon such exercise
the “Net Number” of Warrant Shares determined according to the following formula
(a “Cashless Exercise”): 

	 	Net Number = (A x B) - (A x C) 
	 	                                     
      B 
	 	  
	 	For purposes of the foregoing formula: 

A = the total number of Warrant Shares
with respect to which the Warrants are then being exercised. 

- 4 - 

B = the Weighted Average Price (as
defined below) of the Common Shares (as reported by Bloomberg) for the five
consecutive trading days ending on the date immediately preceding the date of
the Exercise Notice. 

C = the Exercise Price then in effect
for the applicable Warrant Shares at the time of such exercise. 

As used in this Warrant Certificate, “Weighted Average
Price” means, for any security as of any date, the dollar volume-weighted
average price for such security on the Principal Market during the period
beginning at 9:30:01 a.m., New York City time, and ending at 4:00:00 p.m., New
York City time, as reported by Bloomberg through its “Volume at Price” function
or, if the foregoing does not apply, the dollar volume-weighted average price of
such security in the over-the-counter market on the electronic bulletin board
for such security during the period beginning at 9:30:01 a.m., New York City
time, and ending at 4:00:00 p.m., New York City time, as reported by Bloomberg,
or, if no dollar volume-weighted average price is reported for such security by
Bloomberg for such hours, the average of the highest closing bid price and the
lowest closing ask price of any of the market makers for such security as
reported in the “pink sheets” by OTC Pink. If the Weighted Average Price cannot
be calculated for such security on such date on any of the foregoing bases, the
Weighted Average Price of such security on such date shall be the fair market
value as mutually determined by the Company and the Holder. All such
determinations shall be appropriately adjusted for any share dividend, share
split or other similar transaction during such period. 

For the avoidance of doubt, in the event that these Warrants
may not be exercised for cash pursuant to Section 1.1 hereof due to the lack of
a then effective and current registration statement registering the Warrant
Shares with the Commission and an exemption from registration or qualification
under applicable federal and state securities laws is not otherwise available
for such exercise, the sole method of exercise available to a Holder shall be a
“cashless exercise” pursuant to Section 1.5 hereof. Notwithstanding anything
contained herein to the contrary, in no event shall the Holder be entitled to
demand a “net cash settlement” of these Warrants.

	1.6 	Beneficial Ownership. 

The Company shall not effect the exercise of the Warrants, and
the Holder shall not have the right to exercise the Warrants, to the extent that
after giving effect to such exercise, such person (together with such person’s
affiliates (as such term is defined in the Securities Exchange Act of 1934, as
amended (the “Exchange Act”))) would beneficially own in excess of 4.99%
(the “Maximum Percentage”) of the Common Shares outstanding immediately
after giving effect to such exercise. For purposes of the foregoing sentence,
the aggregate number of Common Shares beneficially owned by such person and its
affiliates shall include the number of Warrant Shares issuable upon exercise of
the Warrants with respect to which the determination of such sentence is being
made, but shall exclude Warrant Shares which would be issuable upon (i) exercise
of the remaining, unexercised portion of the Warrants beneficially owned by such
person and its affiliates and (ii) exercise or conversion of the unexercised or
unconverted portion of any other securities of the Company beneficially owned by
such person and its affiliates (including, without limitation, any convertible
notes or convertible preferred shares or warrants) subject to a limitation on conversion or exercise analogous to
the limitation contained herein. Except as set forth in the preceding sentence,
for purposes of this paragraph, beneficial ownership shall be calculated in
accordance with Section 13(d) of the Exchange Act. For purposes of this Warrant
Certificate, in determining the number of outstanding Common Shares, the Holder
may rely on the number of outstanding Common Shares as reflected in the most
recent of (1) the Company’s most recent Annual Report on Form 10-K, as
applicable, Quarterly Report on Form 10-Q, or other public filing by the Company
with the Securities and Exchange Commission, as the case may be, (2) a more
recent public announcement by the Company, or (3) any other notice by the
Company or the Transfer Agent setting forth the number of Common Shares
outstanding. In any case, the number of outstanding Common Shares shall be
determined after giving effect to the conversion or exercise of securities of
the Company, including the Warrants, by the Holder and its affiliates since the
date as of which such number of outstanding Common Shares was reported. By
written notice to the Company, the Holder may from time to time increase or
decrease the Maximum Percentage to any other percentage not in excess of 9.99%
specified in such notice; provided that (i) any such increase will not be
effective until the sixty-first (61st) day after such notice is
delivered to the Company, and (ii) any such increase or decrease will apply only
to the Holder. The provisions of this paragraph shall be construed, corrected
and implemented in a manner so as to effectuate the intended beneficial
ownership limitation herein contained. 

- 5 - 

	1.7 	Fractional Warrant Share. 

Fractional Warrant Shares shall not be issued upon the exercise
of any Warrants. As to any fraction of a share which the Holder would otherwise
be entitled to purchase upon such exercise, the Company shall, at its election,
either pay a cash adjustment in respect of such final fraction in an amount
equal to such fraction multiplied by the Exercise Price or round up to the next
whole Warrant Share. 

	2. 	Anti-Dilution Protection.

      on the Common Shares in its immediately preceding fiscal year; (ii) the
      arithmetic mean of the aggregate value of dividends declared payable by
      the Company on the Common Shares in its three immediately preceding fiscal

The Exercise Price and the number of Warrant Shares shall,

manner provided as follows: 

	 	(a) 	
      If and whenever during the Adjustment Period, the Company
      shall: 

	 	(i) 	
      declare a dividend or make a distribution on its Common
      Shares payable in Common Shares (or securities exchangeable for or
      convertible into Common Shares), other than Dividends Paid in the Ordinary
      Course; or 

	 	 	
       

	 	(ii) 	
      subdivide or change its outstanding Common Shares into a
      greater number of Common Shares; or 

- 7 - 

	 	(iii) 	
      reduce, combine or consolidate its outstanding Common
      Shares into a lesser number or Common Shares, 

	 		
      (any of such events in paragraphs (i), (ii) or (iii)
      above being called a “Share Reorganization”), then effective
      immediately after the record date or effective date, as the case may be,
      at which the holders of Common Shares are determined for the purposes of
      the Share Reorganization, the Exercise Price shall be adjusted to a price
      determined by multiplying the applicable Exercise Price in effect on such
      effective date or record date by a fraction, the numerator of which shall
      be the number of Common Shares outstanding on such effective date or
      record date before giving effect to such Share Reorganization and the
      denominator of which shall be the number of Common Shares outstanding
      immediately after giving effect to such Share Reorganization (including,
      in the case where securities exchangeable for or convertible into Common
      Shares are distributed, the number of additional Common Shares that would
      have been outstanding had such securities been exchanged for or converted
      into Common Shares immediately after giving effect to such Share
      Reorganization). 

	 	 	
       

	 	(b) 	
      If and whenever during the Adjustment Period the Company
      shall fix a record date for the payment, issue or distribution to all or
      substantially all of the holders of the Common Shares of (i) a dividend,
      (ii) cash or assets (including evidences of the Company’s indebtedness),
      or (iii) rights or other securities (including without limitation,
      securities convertible into or exchangeable for Common Shares), and such
      payment, issue or distribution does not constitute a Dividend Paid in the
      Ordinary Course or a Share Reorganization (any of such non-excluded events
      being herein called a “Special Distribution”), the Exercise Price
      shall be adjusted as determined by action of the directors (whose
      determination shall be conclusive) effective immediately after such record
      date by an amount that is no greater than the difference between (x) the
      volume weighted average trading price of the Common Shares on the
      Principal Market for the five (5) most recent Trading Days ending
      immediately prior to the Trading Day the Common Shares begin trading on an
      “ex-distribution” basis, and (y) the volume weighted average trading price
      of the Common Shares on the Principal Market for the five (5) most recent
      Trading Days beginning immediately after the Trading Day the Common Shares
      commence trading on an “ex-distribution” basis. 

	 	 	
       

	 		
      Such adjustment shall be made successively whenever such
      a record date is fixed. To the extent that such payment, issuance or
      distribution is not so made or any rights, options or warrants so
      distributed are not exercised, the Exercise Price shall be readjusted
      effective immediately to the Exercise Price which would then be in effect
      based upon such payment, issuance or distribution actually made, or based
      on the Common Shares or securities exchangeable or convertible for Common
      Shares actually delivered upon the exercise of any rights, options or
      warrants as the case may be but subject to any other adjustment required
      hereunder by reason of any event arising after the record date.
  

- 8 - 

	 	(c) 	
      If and whenever at any time during the Adjustment Period
      there shall be a reorganization, reclassification or other change of
      Common Shares at any time outstanding or change of the Common Shares into
      other shares or into other securities (other than a Share Reorganization),
      or a consolidation, amalgamation, arrangement or merger of the Company
      with or into any other company or other entity, or a transfer of all or
      substantially all of the undertaking or assets of the Company to another
      company or entity, in each case in which the holders of Common Shares are
      entitled to receive shares, other securities or property, including cash,
      (any of such events being herein called a “Capital
      Reorganization”), any Holder who exercises his right to subscribe for
      and purchase Warrant Shares pursuant to the exercise of the Warrants after
      the effective date of such Capital Reorganization shall be entitled to
      receive, and shall accept for the same aggregate consideration in lieu of
      the number of Warrant Shares to which such Holder was theretofore entitled
      upon such exercise, the aggregate number of shares, other securities or
      other property, including cash, which such Holder would have received as a
      result of such Capital Reorganization had he exercised his right to
      acquire Warrant Shares immediately prior to the effective date or record
      date, as the case may be, of the Capital Reorganization and had he been
      the holder of such Warrant Shares on such effective date or record date,
      as the case may be, subject to adjustment thereafter in accordance with
      provisions the same, as nearly as may be possible, as those contained in
      subsection 2.2(b). If determined appropriate by the directors, acting
      reasonably, and subject to any required prior approval of the NYSE Amex,
      TSX and any other stock exchange or market on which the Common Shares may
      be listed or traded, appropriate adjustments shall be made as a result of
      any such Capital Reorganization in the application of the provisions set
      forth in this subsection 2.2, with respect to the rights and interests
      thereafter of a Holder to the end that the provisions set forth in this
      subsection 2.2 shall thereafter correspondingly be made applicable as
      nearly as may reasonably be in relation to any shares, other securities or
      other property, including cash, thereafter deliverable upon the exercise
      of any Warrant. Any such adjustments shall be made by and set forth in an
      agreement supplemental hereto approved by action by the directors, acting
      reasonably, and shall for all purposes be conclusively deemed to be
      appropriate adjustments. 

	 	 	
       

	 	(d) 	
      If and whenever at any time during the Adjustment Period
      there shall occur a Share Reorganization which results in an adjustment to
      the Exercise Price pursuant to subsection 2.2(a), the number of Warrants
      Shares purchaseable (at the adjusted Exercise Price) shall be adjusted
      contemporaneously with the adjustment of the Exercise Price by multiplying
      the number of Warrant Shares theretofore purchaseable on the exercise
      thereof by a fraction, the numerator of which shall be the applicable
      Exercise Price in effect immediately prior to such adjustment and the
      denominator of which shall be the applicable Exercise Price resulting from
      such adjustment. 

- 9 - 

	 	(e) 	
      In case the Company during the Adjustment Period shall
      take any action affecting the Common Shares, other than action described
      above in this subsection 2.2 which in the opinion of the directors, acting
      reasonably, would materially adversely affect the rights of the Holder,
      the Exercise Price or the number of Warrant Shares shall be adjusted in
      such manner, if any, and at such time, by action by the directors, acting
      reasonably, as they may determine to be equitable in the circumstances,
      but subject in all cases to any necessary regulatory approval.
  

	2.3 	Rules. 

For the purposes of subsection 2.2 hereof, any adjustment shall
be made successively whenever an event referred to therein shall occur, subject
to the following provisions: 

	 	(a) 	
      subject to subsection 2.3(b), as to any fraction of a
      Common Share which the Holder would otherwise be entitled upon the
      occurrence of the adjustment(s) described above, the Company shall, at its
      election, either pay a cash adjustment in respect of such final fraction
      in an amount equal to such fraction multiplied by the then applicable
      Exercise Price or round up to the next whole share; 

	 	 	
       

	 	(b) 	
      no adjustment to an Exercise Price shall be required
      unless such adjustment would result in a change of at least 1% in the
      prevailing Exercise Price and no adjustment in the number of Warrant
      Shares will be required to be made unless the cumulative effect of such
      adjustment or adjustments would change the number of Warrant Shares by at
      least one Warrant Share and, for greater clarity, any adjustment which,
      except for the qualification of this section, would otherwise have been
      required to be made shall be carried forward and taken into account in any
      subsequent adjustment; provided, however, that in no event shall the
      Company be obligated to issue fractional Warrant Shares or fractional
      interests in Warrant Shares upon exercise of a Warrant; 

	 	 	
       

	 	(c) 	
      if a dispute shall at any time arise with respect to
      adjustments to the Exercise Price or the number of Warrant Shares
      purchasable pursuant to the exercise rights represented by a Warrant, such
      disputes shall be conclusively determined by the Company’s auditors or, if
      they are unable or unwilling to act, by such other firm of independent
      chartered accountants as may be selected by action by the directors and
      any such determination, shall be conclusive evidence of the correctness of
      any adjustments made; 

	 	 	
       

	 	(d) 	
      if the Company shall set a record date to determine the
      holders of its Common Shares for the purpose of entitling them to receive
      any dividend or distribution or any subscription or purchase rights,
      options or warrants and shall thereafter and before the distribution to
      such shareholders of any such dividend, distribution or subscription or
      purchase rights legally abandon its plan to pay or deliver such dividend,
      distribution or subscription or purchase rights, then no adjustment in the
      Exercise Price or the number of Warrant Shares shall be required by reason
      of the setting of such record date; and 

- 10 - 

	 	(e) 	
      in any case in which this Warrant Certificate requires
      that an adjustment become effective immediately after a record date for an
      event referred to in subsection 2.2 hereof, the Company may defer, until
      the occurrence of such event: 

	 	(i) 	
      issuing to the Holder, to the extent that the Warrants
      are exercised after such record date and before the occurrence of such
      event, the additional Warrant Shares issuable upon such exercise by reason
      of the adjustment required by such event; and 

	 	 	
       

	 	(ii) 	
      delivering to the Holder any distribution declared with
      respect to such additional Warrant Shares after such record date and
      before such event; 

provided, however, that the Company
delivers to the Holder an appropriate instrument evidencing the right of the
Holder, upon the occurrence of the event requiring the adjustment, to an
adjustment in the Exercise Price and/or the number of Warrant Shares. 

	2.4 	Taking of Actions. 

As a condition precedent to the taking of any action which
would require an adjustment pursuant to Section 2.2 hereof, the Company shall
take any action that 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
of the Common Shares which the Holder is entitled to receive in accordance with
the provisions of this Warrant Certificate. 

	2.5 	Notice. 

At least seven days prior to the effective date or record date,
as the case may be, of any event that requires or that may require an adjustment
in any of the exercise rights of the Holder under this Warrant Certificate,
including the number of Warrant Shares, the Company shall deliver to the Holder
a certificate of the Company specifying the particulars of such event and, if
determinable, the required adjustment and the computation of such adjustment. In
case any adjustment for which a certificate has been given is not then
determinable, the Company shall promptly after such adjustment is determinable
deliver to the Holder hereof a certificate of the Company showing how such
adjustment was computed. The Company hereby covenants and agrees that the
register of transfers and share transfer books for the Common Shares shall be
open during normal business hours for inspection by the Holder, and that the
Company will not take any action which might deprive the Holder of the
opportunity of exercising the rights of subscription contained in this Warrant
Certificate, during such seven day period. 

	3. 	Shares to be Reserved. 

The Company will at all times take all action necessary to
reserve and keep available out of its authorized Common Shares, solely for the
purpose of issue upon the exercise of the Warrants, 100% of the number of
Warrant Shares as are then issuable upon the exercise of the Warrants (without
regard to any limitations on exercise). The Company covenants and agrees that
all Warrant Shares that are so issuable will, upon issuance in accordance with
the terms of this Warrant Certificate and applicable laws, be duly
authorized, fully paid and non-assessable. The Company will take such actions as
may be reasonably necessary and as are within its power to ensure that all such
Warrant Shares may be so issued without violation of any applicable laws or the
applicable requirements of any stock exchange upon which the Common Shares of
the Company may be listed. 

- 11 - 

	4. 	Noncircumvention. 

The Company hereby covenants and agrees that the Company will
not, by amendment of its Certificate of Incorporation or through any
reorganization, transfer of assets, consolidation, merger, scheme of
arrangement, dissolution, issue or sale of securities, or any other voluntary
action, avoid or seek to avoid the observance or performance of any of the terms
of this Warrant Certificate, and will at all times in good faith comply with all
the provisions of this Warrant Certificate and take all actions consistent with
effectuating the purposes of this Warrant Certificate. Without limiting the
generality of the foregoing, the Company shall take all such actions as may be
necessary or appropriate in order that the Company may validly and legally issue
fully paid and nonassessable Common Shares upon the exercise of the Warrants.

	5. 	Warrant Holder Not Deemed a Shareholder.
  

Except as otherwise specifically provided herein, the Holder,
solely in such person’s capacity as a holder of the Warrants, shall not be
entitled to vote or receive dividends or be deemed the holder of share capital
of the Company for any purpose, nor shall anything contained in this Warrant
Certificate be construed to confer upon the Holder, solely in such person’s
capacity as the Holder of the Warrants, any of the rights of a shareholder of
the Company or any right to vote, give or withhold consent to any corporate
action (whether any reorganization, issue of shares, reclassification of share
capital, consolidation, merger, conveyance or otherwise), receive notice of
meetings, receive dividends or subscription rights, or otherwise, prior to the
issuance to the Holder of the Warrant Shares which such person is then entitled
to receive upon the due exercise of a Warrant. In addition, nothing contained in
this Warrant Certificate shall be construed as imposing any liabilities on the
Holder to purchase any securities (upon exercise of a Warrant or otherwise) or
as a shareholder of the Company, whether such liabilities are asserted by the
Company or by creditors of the Company. 

	6. 	The Register. 
	 	 
		The Company shall keep: 

	 	(a) 	
      at the principal office of the Company, a register of
      holders of the Warrants represented by this Warrant Certificate or any
      portion thereof in which shall be entered in alphabetical order the names

      and 

	 	 	
       

	 	(b) 	
      at the principal office of the Company, a register of
      transfers in which all transfers of the Warrants represented by this
      Warrant Certificate or any portion thereof and the date and other
      particulars of each transfer shall be entered.

applicable laws, the Warrants evidenced hereby and/or any portion of the rights
to subscribe for and purchase Warrant Shares hereunder may be transferred by the
Holder. No transfer of the Warrants evidenced hereby or any portion of the
rights hereunder will be valid unless duly entered on the appropriate register
of transfers, upon the surrender to the Company of this Warrant Certificate
accompanied by a duly completed Transfer Form in substantially the form attached
as Exhibit “2” hereto executed by the registered Holder or its executors,

loss, theft, destruction or mutilation of this Warrant Certificate and, if
requested by the Company, upon delivery of an indemnity and/or surety bond in
amount and form satisfactory to the Company (or, in the case of mutilation, upon
surrender of this Warrant Certificate), the Company shall issue and deliver to
the Holder a replacement certificate containing the same legends, terms and
conditions as this Warrant Certificate. 

	9. 	Expiry Date.
