To the extent permitted by applicable law, the Corporation may, at any time and from time to time, purchase Warrants by invitation for tender, by private contract, on any stock exchange, in the open market or otherwise (which shall include a purchase through an investment dealer or firm holding membership on a United States national securities exchange registered pursuant to Section 6 of the U.S. Exchange Act, interdealer quotation system or Canadian stock exchange) on such terms as the Corporation may determine. All Warrants purchased pursuant to the provisions of this Section 2.8 shall be forthwith delivered to and cancelled by the Warrant Agent and shall not be reissued. If required by the Corporation, the Warrant Agent shall furnish the Corporation with a certificate as to such cancellation.

2.9 Cancellation of Surrendered Warrants

All Warrant Certificates surrendered to the Warrant Agent in accordance with the provisions of this Warrant Indenture will be cancelled by the Warrant Agent and, if requested in writing in advance by the Corporation, the Warrant Agent will furnish the Corporation with a cancellation certificate identifying each Warrant Certificate so cancelled.

2.10 Warrantholder not a Shareholder

Nothing in this Warrant Indenture or in the holding of a Warrant evidenced by a Warrant Certificate, or otherwise, will be construed as conferring on any Warrantholder, in such Warrantholder’s capacity as a Warrantholder, any right or interest whatsoever as a shareholder of the Corporation, including but not limited to any right to vote at, to receive notice of, or to attend any meeting of shareholders or any other proceeding of the Corporation or any right to receive any dividend or other distribution, including the rights to be issued pursuant to the Rights Offering.

2.11 Global Warrant Certificates

(a) Warrants may, upon original issuance, be issued in the form of one or more global Warrant Certificates, representing the Warrants to be delivered to the Clearing Agency by or on behalf of the Corporation in respect of such Warrants. The Warrants shall initially be registered on the Warrant register in the name of the Clearing Agency or its nominee and no Warrantholder will receive definitive Warrant Certificates representing such Warrantholder’s interest in the Warrants, except as provided in Subsection 2.11(c) or upon due request by such Warrantholder. Unless and until definitive Warrants have been issued to the applicable Warrantholders pursuant to Subsection 2.11(c):

(i) the provisions of this Section 2.11 shall be in full force and effect;

(ii) the Corporation and the Warrant Agent may deal with the Clearing Agency for all purposes (including the making of payments and the delivery of any notice, report or other communication) as the registered holder of the Warrants and as the authorized representative of the respective Warrantholders;

(iii) to the extent that the provisions of this Section 2.11 conflict with any other provisions of this Indenture, the provisions of this Section 2.11 shall prevail;

(iv) the rights of the respective Warrantholders shall be exercised only through the Clearing Agency (directly or by proxy in favour of the respective Participants) and shall be limited to those established herein and by law;

(v) all transfers and exchanges of Warrants evidenced by a global certificate must be made through the Clearing Agency and any person transferring a Warrant in such manner shall be deemed to have transferred to the transferee all of such person’s rights and obligations in respect thereof; all transferees of Warrants shall be deemed to have received and accepted such transfer and be deemed to have agreed to be bound by the provisions of this Indenture;

(vi) all transfers of beneficial ownership in any Warrant represented by a global Warrant Certificate will be effected only (i) with respect to the interest

of a Participant, through records maintained by the Clearing Agency or its nominee for such global Warrant Certificate, and (ii) with respect to the interest of any person other than a Participant, through records maintained by Participants. Beneficial owners of Warrants who are not Participants but who desire to sell or otherwise transfer ownership of or any other interest in Warrants represented by such global Warrant Certificate may do so only through a Participant; and

(vii) for purposes of any provision of this Indenture requiring or permitting actions with the consent of, or at the direction of, holders of Warrants evidencing a specified percentage of the aggregate unpaid principal amount of Warrants then outstanding, the Warrant Agent is entitled to act and rely upon the instructions of the Clearing Agency that it has received instructions, directly or indirectly through its respective Participants, to such effect from such Warrantholders owning or representing, respectively, the requisite percentage of Warrants.

(b) Each of the parties hereto acknowledges and agrees that such Warrantholders through their respective Participants are collectively entitled, under the terms hereof, to all of the rights accorded to registered holders of Warrants and are bound by all of the obligations of such Warrantholders.

(c) If Warrants have been issued in the manner described by Section 2.11(a) and (i) the Corporation advises the Warrant Agent that any Clearing Agency is no longer willing or able to discharge properly its responsibilities as the Clearing Agency with respect to such Warrants and the Clearing Agency is unable to locate a qualified successor; or (ii) the Corporation, at its option, advises the Warrant Agent that it elects to terminate the use of the global certificate procedure described in Section 2.11(a) with respect to the Warrants of any particular series; then the Warrant Agent shall notify the relevant holders of the Warrants, through the Clearing Agency, of the occurrence of any such event and of the availability of definitive Warrants to Warrantholders requesting the same. Upon surrender by the Clearing Agency of a global certificate or certificates representing the Warrants and accompanied by registration instructions from the Clearing Agency for re-registration, and provided that the Corporation shall have provided the Warrant Agent with sufficient blank forms of certificates representing definitive Warrants, the Warrant Agent shall certify and deliver such definitive Warrants. Neither the Corporation nor the Warrant Agent shall be liable for any delay in delivery of such instructions and may conclusively act and rely on, and shall be protected in acting and relying on, such instructions. The Warrant Agent shall not be liable for any delay in the delivery to it of certificates representing definitive Warrants for certification and delivery, or for any resulting delay in the delivery of such certificates to any holder. Upon the issuance of such definitive Warrants, the Corporation and the Warrant Agent shall recognize the registered holders of such definitive Warrants as Warrantholders hereunder.

(d) If definitive Warrants have been issued and thereafter the Warrant Agent advises the Corporation of the availability of the global certificate procedure

described in Section 2.11(a) in regard to such Warrants, the Warrant Agent and the Corporation may agree to allow for the re-registration of such definitive Warrants under such procedure and the Warrant Agent shall forthwith deliver notice thereof to each registered holder of such Warrants. Upon surrender by any such Warrantholder of its definitive Warrant accompanied by instructions for re-registration of the Warrant under such procedure, such Warrant shall thereafter be re-registered under such procedure and be subject to Subsections 2.11(a), (b) and (c), mutatis mutandis. The Corporation shall pay all expenses incurred by the Warrant Agent and the reasonable fees of the Warrant Agent associated with any termination of the use of such procedure and of any such re-registration of the definitive Warrants under such procedure.

(e) Notwithstanding anything herein or in the terms of the Warrant Certificates to the contrary, neither the Corporation nor the Warrant Agent nor any agent thereof shall have any responsibility or liability for (i) the records maintained by the Clearing Agency relating to any ownership interests or any other interests in the Warrants or the depository system maintained by the Clearing Agency, or payments made on account of any ownership interest or any other interest of any person in any Warrant represented by any global Warrant Certificate (other than the applicable Clearing Agency or its nominee), (ii) for maintaining, supervising or reviewing any records of the Clearing Agency or any Participant relating to any such interest, or (iii) any advice or representation made or given by the Clearing Agency or those contained herein that relate to the rules and regulations of the Clearing Agency or any action to be taken by the Clearing Agency on its own direction or at the direction of any Participant.

The transferee of any Warrant will, after surrender to the Warrant Agent of the Warrant Certificate evidencing such Warrant as required by Subsection 3.1(b) hereof and upon compliance with all other conditions in respect thereof required by this Warrant Indenture or by law, be entitled to be entered on the register of holders referred to in Subsection 3.1(a) hereof, or on any branch registers of holders maintained pursuant to Subsection 3.1(g) hereof, as the owner of such Warrant free from all equities or rights of set-off or counterclaim between the Corporation and the transferor or any previous holder of such Warrant, except in respect of equities of which the Corporation is required to take notice by statute or by order of a court of competent jurisdiction.

(d) Refusal of Registration. The Corporation will be entitled, and may direct the Warrant Agent, to refuse to recognize any transfer, or enter the name of any transferee, of any Warrant on the registers referred to in Subsection 3.1(a) hereof, or on any branch registers maintained pursuant to Subsection 3.1(g) hereof, if such transfer would constitute a violation of the securities laws of any jurisdiction or the rules, regulations or policies of any regulatory authority having jurisdiction. The Warrant Agent is entitled to assume compliance with all applicable securities legislation unless otherwise notified in writing by the Corporation. No duty will rest with the Warrant Agent to determine compliance of the transferee or transferor of any Warrant with applicable securities registration. The Warrant Agent may, when deemed necessary, acting reasonably, contact the Corporation or counsel to confirm the validity of any transfer of Warrants prior to completing same.

(e) No Notice of Trusts. Subject to applicable law, neither the Corporation nor the Warrant Agent will be bound to take notice of or see to the execution of any trust, whether express, implied or constructive, in respect of any Warrant, and may transfer any Warrant on the direction of the person registered as the holder thereof, whether named as trustee or otherwise, as though that person were the beneficial owner thereof.

(f) Inspection. The Warrant Agent will from time to time when requested to do so in writing by the Corporation or any Warrantholder (upon payment of the Warrant Agent’s reasonable charges), furnish the Corporation or such Warrantholder, as the case may be, with a list of the names and addresses of holders of Warrants entered on such registers and showing the number of Warrants held by each such holder.

(g) Location of Registers. The Corporation may at any time and from time to time change the place at which the registers referred to in Subsection 3.1(a) hereof are kept, cause branch registers of holders or transfers to be kept at other places and close such branch registers or change the place at which such branch registers are kept, in

each case subject to the approval of the Warrant Agent. Notice of all such changes or closures shall be given by the Corporation to the Warrant Agent and to holders of Warrants in accordance with Section 10.2 hereof.

3.2 Exchange of Warrant Certificates

(a) Exchange. One or more Warrant Certificates may, on compliance with the reasonable requirements of the Warrant Agent, be exchanged for one or more Warrant Certificates of different denominations evidencing in the aggregate an equal number of Warrants as the Warrant Certificate or Warrant Certificates being exchanged.

(b) Place of Exchange. Warrant Certificates may be exchanged only at the office in Toronto, Ontario of the Warrant Agent or at any other place designated by the Corporation with the approval of the Warrant Agent.

(c) Cancellation. Any Warrant Certificate tendered for exchange pursuant to this Section shall be surrendered to the Warrant Agent and cancelled.

(d) Execution. The Corporation will sign all Warrant Certificates necessary to carry out exchanges pursuant to this Section 3.2 and such Warrant Certificates will be certified by the Warrant Agent.

(e) Charges. The Warrant Agent may charge Warrantholders requesting an exchange of Warrant Certificates a reasonable sum for each Warrant Certificate issued; and payment of such charges and reimbursement of the Warrant Agent or the Corporation for any and all taxes or governmental or other charges required to be paid shall be made by the party requesting such exchange as a condition precedent to such exchange.

3.3 Ownership of Warrants

(a) Owner. The Corporation and the Warrant Agent may deem and treat the person in whose name any Warrant is registered as the absolute owner of such Warrant for all purposes, and such person will for all purposes of this Indenture be and be deemed to be the absolute owner thereof, and the Corporation and the Warrant Agent will not be affected by any notice or knowledge to the contrary except as required by statute or by order of a court of competent jurisdiction.

(b) Rights of Registered Holder. The registered holder of any Warrant will be entitled to the rights evidenced thereby free from all equities and rights of set-off or counterclaim between the Corporation and the original or any intermediate holder thereof and all persons may act accordingly, and the issue and delivery to any such registered holder of the Warrant Shares issuable pursuant thereto will be a good discharge to the Corporation and the Warrant Agent therefor and neither the Corporation nor the Warrant Agent will be bound to inquire into the title of any such registered holder.

ARTICLE 4 - EXERCISE OF WARRANTS

4.1 Exercise

(a) Exercise. Subject to the limitations set forth in Subsection 4.1(c), Section 4.7 and Section 4.9 hereof, the holder of any Warrant may at any time commencing on the Effective Date and terminating at the Expiry Time exercise the right thereby conferred, to be issued Warrant Shares by surrendering to the Warrant Agent at the office in Toronto, Ontario of the Warrant Agent, or to any other person or at any other place designated by the Corporation with the approval of the Warrant Agent, during normal business hours on a Business Day, the Warrant Certificate evidencing such Warrant, or a CDS “NCI letter of instruction” evidencing such Warrants, if applicable, and a duly completed and executed notice of exercise substantially in the form set out in such Warrant Certificate specifying the number of Warrant Shares subscribed for together with a certified cheque, bank draft or money order in lawful money of the United States, payable to or to the order of the Corporation in an amount equal to the Exercise Price multiplied by the number of Warrant Shares subscribed for. A beneficial owner of Warrants who desires to exercise Warrants should ensure that the Participant is provided with the required exercise form sufficiently in advance of the relevant notice date so as to permit the Participant to deliver notice to the Clearing Agency and so as to permit the Clearing Agency to deliver notice to the Corporation by the required time. Any expense associated with the preparation and delivery of such exercise form will be for the account of the beneficial owner exercising the Warrants.

(b) Cashless Exercise. If, at any time following the initial effectiveness of a Registration Statement and the filing of the Supplement under the U.S. Securities Act and prior to the Expiry Date, the Corporation determines that such Registration Statement filed with the SEC is not effective, the Corporation shall promptly provide written notice of such determination to the Warrant Agent. Upon receipt of such notice, the Warrant Agent shall provide a copy thereof to each Warrantholder, and confirm in writing that the then outstanding Warrants may, until the earlier of the Registration Statement becoming effective and the Supplement having been filed or the Expiry Date, also be exercised by means of a “cashless exercise” in which the Warrantholder shall be entitled to receive a certificate for the number of Common Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

(i) A = the VWAP on the trading day immediately preceding the date of the receipt by the Warrant Agent of the notice of exercise;

(ii) B = the Exercise Price of each Warrant, as adjusted; and

(iii) X = the number of Warrant Shares issuable upon exercise of the Warrants in accordance with their terms by means of a cash exercise rather than a cashless exercise.

(c) Restrictions. The exercise of the Warrants pursuant to Subsections 4.1(a) and (b) shall be subject to compliance with, and may be restricted by, applicable securities

legislation and the resale of the Warrant Shares may be restricted by such securities legislation.

(d) Surrender of Warrant Certificates. Any Warrant Certificate with a duly completed and executed notice of exercise, and if applicable an “NCI letter of instruction”, referred to in Subsection 4.1(a) hereof will be deemed to have been surrendered to the Warrant Agent only on personal delivery thereof to, or, if sent by mail or other means of transmission, on actual receipt thereof by, the Warrant Agent or one of the other persons at the office or one of the other places specified in Subsection 4.1(a) hereof.

(e) Notice of Exercise. Any notice of exercise referred to in Subsections 4.1(a) and (b) hereof must be signed by the Warrantholder, or his executors, administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Warrant Agent, acting reasonably, and, if any Warrant Shares thereby issuable are to be issued to a person or persons other than the Warrantholder, must specify the name or names and the address or addresses of each such person or persons and the number of Warrant Shares to be issued to each such person if more than one is so specified.

(f) Exercise of Less than All. The holder of any Warrant Certificate who wishes to exercise the Warrants evidenced by such Warrant Certificate may exercise less than all of such Warrants and in the case of any such partial exercise shall be entitled to receive a Warrant Certificate, in form, signed and certified in accordance with the provisions of Article 2 hereof, evidencing the number of Warrants held by the Warrantholder which remain unexercised.

4.2 Effect of Exercise

(a) Effect of Exercise. Upon the exercise of any Warrants in accordance with Section 4.1 hereof, the Warrant Shares thereby issuable shall be deemed to have been issued, and the person or persons to whom such Warrant Shares are to be issued shall be deemed to have become the holder or holders of record thereof, on the Exercise Date, unless the transfer registers for the Warrant Shares are closed on that date, in which case such Warrant Shares shall be deemed to have been issued and such person or persons shall be deemed to have become the holder or holders of record thereof on the date on which such transfer registers are reopened, but such Warrant Shares shall be issued on the basis of the number of Warrant Shares to which such person or persons were entitled on the Exercise Date.

(b) Mailing of Certificates. As soon as reasonably practicable, and in any event not later than three (3) Business Days after the surrender to the Warrant Agent of the Warrant Certificates in accordance with Subsection 4.1(d), the Corporation shall, subject to the provisions of Section 4.6, cause the Warrant Agent to mail by way of first class insured mail to the person or persons in whose name or names the Warrant Shares thereby issued have been issued, at his or their respective addresses, or, if so specified, cause to be delivered to such person or persons at the place where the

Warrant Certificates evidencing such Warrants were surrendered, certificates representing the Warrant Shares so issued.

(c) Issue to Other than Holder. If any Warrant Shares issuable pursuant to any Warrants are to be issued to a person or persons other than the Warrantholder, the Warrantholder must pay to the Corporation or to the Warrant Agent on its behalf an amount equal to all exigible transfer taxes or other government charges, and neither the Corporation nor the Warrant Agent will be required to issue or deliver any certificates representing any such Warrant Shares unless or until such amount has been so paid or the Warrantholder has established to the satisfaction of the Corporation that such taxes and charges have been paid or that no such taxes or charges are owing.

(d) Restrictions. If at the time of exercise of the Warrants there remain trading restrictions on the Warrant Shares pursuant to applicable securities legislation, the Corporation or the Warrant Agent shall, upon the advice of counsel, endorse any Warrant Share to such effect.

4.3 No Fractional Warrant Shares

The Corporation shall not be required to issue fractional Warrant Shares in satisfaction of its obligations hereunder and no cash or other consideration will be paid in lieu of fractional shares. Any subscription for fractional Warrant Shares will be deemed to be a subscription for the next largest whole number of Warrant Shares.

4.4 Warrants Void After Expiry Time

After the Expiry Time, no holder of a Warrant Certificate representing a Warrant which has not been validly exercised as set forth herein has any rights either under this Warrant Indenture or the Warrant Certificate, and the Warrants are void and of no value or effect. All provisions of this Warrant Indenture are subject to this Section.

4.5 Recording

The Warrant Agent shall record particulars of each Warrant exercised which particulars shall include the name and address of each person to whom Warrant Shares are thereby issued, the number of Warrant Shares so issued and the Exercise Date in respect thereof. Within three Business Days after each Exercise Date, the Warrant Agent shall provide such particulars in writing to the Corporation.

4.6 Postponement of Delivery of Certificates

The Corporation shall not be required to deliver certificates for Warrant Shares during the period when the transfer books of the Corporation are closed by law and, in the event that the Exercise Date occurs during such period, the delivery of certificates may be postponed for a period not exceeding five days after the date of the re-opening of the transfer books.

4.7 Securities Restrictions

Notwithstanding any provision to the contrary herein, no Warrant Shares will be issued pursuant to the exercise of any Warrant if the issuance of such Warrant Shares would constitute a violation of the securities laws of any applicable jurisdiction, and, without limiting the generality of the foregoing, the Corporation will legend the certificates representing the Warrant Shares if, in the opinion of counsel to the Corporation, such legend is necessary in order to avoid a violation of any securities laws of any applicable jurisdiction or to comply with the requirements of any stock exchange on which the Common Shares are listed; provided that if, at any time, in the opinion of outside counsel to the Corporation, acting reasonably, such legends are no longer necessary in order to avoid a violation of any such laws, or the holder of any such legended certificate, at his expense, provides the Corporation with evidence satisfactory in form and substance to the Corporation (which may include an opinion of counsel of recognized standing satisfactory to the Corporation) to the effect that such holder is entitled to sell or otherwise transfer such securities in a transaction in which such legends are not required, such legended certificates may thereafter be surrendered to the Corporation in exchange for a certificate that does not bear such legends.

4.8 Adjustments.

(a) Definitions. For the purposes of this Section 4.8 unless there is something in the subject matter or context inconsistent therewith, the words and terms defined below shall have the respective meanings specified therefor in this Section:

(i) “Current Market Price” of the Common Shares at any date means the price per share equal to the weighted average price at which the Common Shares have traded (i) on the AMEX, or (ii) if the Common Shares are not then listed on the AMEX, on such other U.S. national securities exchange registered pursuant to Section 6 of the U.S. Exchange Act or Canadian stock exchange as may be selected by the directors of the Corporation for such purpose, or (iii) if the Common Shares are not then listed on any U.S. or Canadian stock exchange, in the over-the-counter market, during the period of any twenty consecutive trading days ending not more than five Business Days before such date; provided that the weighted average price will be determined by dividing the aggregate sale price of all Common Shares sold on the said exchange or market, as the case may be, during the said twenty consecutive trading days by the total number of Common Shares so sold (provided that, in each case, if such average price is not in U.S. dollars, such price will be translated into U.S. dollars using the Exchange Rate in effect on the date of determination); and provided further that if the Common Shares are not then listed on any Canadian stock exchange or traded in the over-the counter market, then the Current Market Price will be determined by such firm of independent chartered accountants as may be selected by the directors; and

(ii) “trading day” with respect to a stock exchange or over-the-counter market means a day on which such stock exchange or market is open for business.

(b) Common Share Reorganization. If and whenever at any time after the date hereof and prior to the Expiry Time the Corporation shall (i) subdivide, redivide or change its then outstanding Common Shares into a greater number of Common Shares, (ii) reduce, combine or consolidate its then outstanding Common Shares into a lesser number of Common Shares or (iii) issue Common Shares (or securities exchangeable for or convertible into Common Shares) to the holders of all or substantially all of its then outstanding Common Shares by way of a stock dividend or other distribution (any of such events herein called a “Common Share Reorganization”), then the Exercise Price shall be adjusted effective immediately after the effective date of any such event in (i) or (ii) above or the record date at which the holders of Common Shares are determined for the purpose of any such dividend or distribution in (iii) above, as the case may be, by multiplying the then applicable Exercise Price in effect on such effective date or record date, as the case may be, by a fraction, the numerator of which shall be the number of Common Shares outstanding on such effective date or record date, as the case may be, 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 additional Common Shares that would be outstanding if such securities were exchanged for or converted into Common Shares after giving effect to such Common Share Reorganization. To the extent that any adjustment in the Exercise Price occurs pursuant to this Subsection 4.8(b) as a result of the fixing by the Corporation of a record date for the distribution of securities exchangeable for or convertible into Common Shares, the Exercise Price will be readjusted immediately after the expiry of any relevant exchange or conversion right to the Exercise Price that would then be in effect based upon the number of Common Shares actually issued and remaining issuable after such expiry and will be further readjusted in such manner upon the expiry of any further such rights.

(c) Rights Offering. If and whenever at any time after the date hereof and prior to the Expiry Time, the Corporation fixes a record date for the issue or distribution to the holders of all or substantially all of the outstanding Common Shares of rights, options or warrants pursuant to which such holders are entitled, during a period expiring not more than 45 days after the record date for such issue (such period being the “Rights Period”), to subscribe for or purchase Common Shares or securities exchangeable for or convertible into Common Shares at a price per Common Share (or in the case of securities exchangeable for or convertible into Common Shares at an exchange or conversion price per Common Share at the date of issue of such securities) which is less than 95% of the Current Market Price of the Common Shares on such record date for such issue (any of such events being herein called a “Rights Offering”), the Exercise Price will be adjusted effective immediately after the Rights Period for the Rights Offering to the amount determined by multiplying the applicable Exercise Price in effect at the end of the Rights Period by a fraction:

(i) the numerator of which will be the sum of:

(1) the number of Common Shares outstanding on the record date for the Rights Offering; and

(2) the number determined by dividing:

(A) either (a) the product of the number of Common Shares offered for issue during the Rights Period pursuant to the exercise of the rights, warrants or options under the Rights Offering and the price at which such Common Shares are offered; or, (b) the product of the exchange or conversion price of the securities so offered and the number of Common Shares for or into which the securities offered pursuant to the Rights Offering may be exchanged or converted; as the case may be, by

(B) the Current Market Price of the Common Shares as of the record date for the Rights Offering; and

(ii) the denominator of which will be the aggregate of the number of Common Shares outstanding on such record date and the number of Common Shares actually issued or subscribed for during the Rights Period upon exercise of the rights, warrants or options pursuant to the Rights Offering (including in the case of the issue or distribution of securities exchangeable for or convertible into Common Shares the number of Common Shares for or into which such securities may be exchanged or converted).

If by the terms of the rights, options, or warrants referred to in this Subsection 4.8(c), there is more than one purchase, conversion or exchange price per Common Share, 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 or exchangeable securities so offered, will be calculated for purposes of the adjustment on the basis of the lowest purchase, conversion or exchange price per Common Share, as the case may be. Any Common Shares owned by or held for the account of the Corporation will be deemed not to be outstanding for the purpose of any such calculation. To the extent that any adjustment in the Exercise Price occurs pursuant to this Subsection 4.8(c) as a result of the fixing by the Corporation of a record date for the issue or distribution of rights, options or warrants referred to in this Subsection 4.8(c), the Exercise Price will be readjusted immediately after the expiry of any relevant exchange, conversion or exercise right to the Exercise Price that would then be in effect based upon the number of Common Shares actually issued and remaining issuable after such expiry and will be further readjusted in such manner upon the expiry of any further such rights.

(d) Special Distribution. If and whenever at any time after the date hereof and prior to the Expiry Time, the Corporation fixes a record date for the payment, issue or distribution to the holders of all or substantially all of the Common Shares of:

(i) Common Shares or other securities of the Corporation;

(ii) rights, options or warrants to acquire Common Shares or securities exchangeable for or convertible into Common Shares (other than rights, options or warrants pursuant to which holders of Common Shares are entitled, during a period expiring not more than 45 days after the record date for such issue, to subscribe for or purchase Common Shares at a price per share (or in the case of securities exchangeable for or convertible into Common Shares at an exchange or conversion price per share at the date of issue of such securities) of at least 95% of the Current Market Price of the Common Shares on such record date);

(iii) evidences of indebtedness of the Corporation; or

(iv) any property or assets (including evidences of the Corporation’s indebtedness) of the Corporation;

and if such issue or distribution does not constitute a Common Share Reorganization or a Rights Offering (any of such non-excluded events being herein called a “Special Distribution”), the Exercise Price will be adjusted effective immediately after the record date for the Special Distribution to the amount determined by multiplying the Exercise Price in effect on the record date for the Special Distribution by a fraction:

(1) the numerator of which will be the difference between:

(A) the product of the number of Common Shares outstanding on such record date and the Current Market Price of the Common Shares on such record date, and

(B) the fair value, as determined in good faith by the directors of the Corporation, to the holders of the Common Shares, of such dividend, cash, securities, rights, options, warrants, evidences of indebtedness or property or assets to be issued or distributed in the Special Distribution, and

(2) the denominator of which will be the product obtained by multiplying the number of Common Shares outstanding on such record date by the Current Market Price of the Common Shares on such record date.

Any Common Shares owned by or held for the account of the Corporation will be deemed not to be outstanding for the purpose of such calculation. To the extent that any adjustment in the Exercise Price occurs pursuant to this Subsection 4.8(d) as a result of the fixing by the Corporation of a record date for the issue or distribution of rights, options or warrants to acquire Common Shares or securities exchangeable for or convertible into Common Shares referred to in this Subsection 4.8(d), the Exercise Price will be readjusted immediately after the expiry of any relevant exercise, exchange or conversion

right to the amount that would then be in effect if the fair market value had been determined on the basis of the number of Common Shares issued and remaining issuable immediately after such expiry, and will be further readjusted in such manner upon the expiry of any further such rights.

(e) Capital Reorganization. If and whenever at any time after the date hereof and prior to the Expiry Time there is a capital reorganization of the Corporation or a reclassification, redesignation or other change in the Common Shares or securities (other than a Common Share Reorganization) or a consolidation, arrangement or merger or amalgamation of the Corporation with or into any other corporation or other entity (other than a consolidation, arrangement, merger or amalgamation which does not result in any reclassification of the outstanding Common Shares or a change of the Common Shares into other securities), or a transfer, sale or conveyance of all or substantially all of the Corporation’s undertaking or assets to another corporation or other entity in which the holders of Common Shares are entitled to receive shares, other securities or other property (any of such events being called a “Capital Reorganization”), the Holder, where the Holder has not exercised the right of subscription and purchase under this Warrant certificate prior to the effective date of such Capital Reorganization, shall be entitled to receive and shall accept, upon the exercise of such right, on such date or any time thereafter, for the same aggregate consideration in lieu of the number of Common Shares to which the Holder was theretofore entitled to subscribe for and purchase upon the exercise of the Warrants, the kind and aggregate number of shares and/or other securities or property resulting from the Capital Reorganization which the Holder would have been entitled to receive as a result of such Capital Reorganization if, on the effective date thereof, the Holder had been the registered holder of the number of Common Shares to which the Holder was theretofore entitled to subscribe for and purchase. If necessary, as a result of any Capital Reorganization, appropriate adjustments will be made in the application of the provisions of this Warrant certificate with respect to the rights and interest thereafter of the Holder to the end that the provisions of this Warrant certificate will thereafter correspondingly be made applicable as nearly as may reasonably be possible in relation to any shares or other securities and/or property thereafter deliverable upon the exercise of the Warrants.

(f) Adjustment to Number of Warrant Shares. If and whenever at any time after the date hereof and prior to the Expiry Time, any of the events set out in Subsections 4.8(b), (c), (d) or (e) shall occur and the occurrence of such event results in an adjustment of the Exercise Price pursuant to the provisions of this Section 4.8, then the number of Warrant Shares purchasable pursuant to this Warrant upon exercise thereof shall be adjusted contemporaneously with the adjustment of the Exercise Price by multiplying the number of Warrant Shares then otherwise purchasable on the exercise thereof by a fraction, the numerator of which shall be the then applicable Exercise Price in effect immediately prior to the adjustment and the denominator of which shall be the Exercise Price resulting from such adjustment.

(g) Deferral of Adjustment. In any case in which this Section shall require that an adjustment shall become effective immediately after a record date for or an effective

date of an event referred to herein, the Corporation may defer, until the occurrence and consummation of such event, issuing to the holder of any Warrant exercised after such record date or effective date and before the occurrence and consummation of such event the additional Warrant Shares or other shares, securities or property issuable upon such exercise by reason of the adjustment required by such event, provided, however, that the Corporation will deliver to such holder an appropriate instrument evidencing such holder’s right to receive such additional Warrant Shares or other shares, securities or property upon the occurrence and consummation of such event and the right to receive any dividend or other distribution in respect of such additional Warrant Shares or other shares, securities or property declared in favour of the holders of record of Common Shares or of such other shares, securities or property on or after the Exercise Date or such later date as such holder would, but for the provisions of this Subsection, have become the holder of record of such additional Warrant Shares or of such other shares, securities or property pursuant hereto.

(h) Adjustments Cumulative. The adjustments provided for in this Section are cumulative and shall, in the case of any adjustment to the Exercise Price, be computed to the nearest one one-hundredth of a Warrant Share and will apply (without duplication) to successive subdivisions, consolidations, distributions, issuances or other events resulting in any adjustment under the provisions of this Section, provided that, notwithstanding any other provision of this Section, no adjustment of the Exercise Price or the number of Warrant Shares purchasable upon the exercise of the Warrants will be required (i) unless such adjustment would require an increase or decrease of at least 1% in the Exercise Price then in effect and a change in the number of Warrant Shares purchasable upon exercise by at least one one-hundredth of a Common Share, as the case may be (provided, however, that any adjustment which by reason of this Subsection is not required to be made will be carried forward and taken into account in any subsequent adjustment), (ii) if, in respect of any event described in this Section (other than the events referred to in subparagraph 4.8(b)(i), subparagraph 4.8(b)(ii) and Subsection 4.8(c)), the holders of Warrants are entitled to participate in such event, or are entitled to participate within 45 days in a comparable event, on the same terms, mutatis mutandis as if the Warrants had been exercised prior to or on the effective date of or record date for such event, (iii) in respect of any Common Shares issuable or issued pursuant to any stock option or stock purchase plan in force from time to time for directors, officers or employees of the Corporation or of a Subsidiary of the Corporation or pursuant to the Warrants, (iv) in respect of any Common Shares issued on the exercise of any other stock options issued by the Corporation and outstanding on the date hereof, or (v) in respect of the issuance of any Common Shares issued as consideration of the acquisition of mining rights, property or shares in the ordinary course of business;

(i) Resolution of Questions. In the event of any question arising with respect to the adjustments provided for in this Section, such questions shall be conclusively determined by the Corporation’s Auditors or, if they are unable or unwilling to act, by such firm of chartered accountants as is appointed by the Corporation and acceptable to the Warrant Agent. Such accountants shall have access to all necessary records of the Corporation and such determination shall be binding upon the Corporation, the

Warrant Agent and the Warrantholders. If any such determination is made, the Corporation shall forthwith deliver a certificate to the Warrant Agent describing such determination and give notice to the Warrantholders of such determination, subject to the prior consent of the AMEX or the TSX.

(j) Other Actions. If and whenever at any time after the date hereof and prior to the Expiry Time, the Corporation shall take any action affecting or relating to the Common Shares, other than any action described in this Section, which in the opinion of the directors or the Warrant Agent would prejudicially affect the rights of any holders of Warrants, the Exercise Price will be adjusted by the directors in such manner, if any, and at such time, as the directors may in their sole discretion determine to be equitable in the circumstances, subject to the prior consent of the AMEX and the TSX or any other exchange on which the Corporation’s securities are then listed to such holders.

(k) Record Date. In the absence of a resolution of the board of directors of the Corporation fixing a record date for a Rights Offering or a Special Distribution, the Corporation shall be deemed to have fixed as the record date therefor the date on which such dividend or distribution is effected. If the Corporation sets a record date to take any action and thereafter and before the taking of such action abandons its plan to take such action, then no adjustment to the Exercise Price will be required by reason of the setting of such record date.

(l) Additional Actions. Subject to the prior consent of the AMEX and the TSX, as a condition precedent to the taking of any action which would require an adjustment in any of the rights under the Warrants, the Corporation will take any action which may, in the opinion of counsel to the Corporation be necessary in order that the Corporation, or any successor to the Corporation or successor to the undertaking or assets of the Corporation, will be obligated to and may validly and legally issue all of the Warrant Shares or other shares, securities or property which the holders of Warrants would be entitled to receive thereafter on the exercise thereof in accordance with the provisions hereof.

(m) Notice to Warrant Agent. At least 10 Business Days before the earlier of the effective date of or record date for any event referred to in this Section that requires or might require an adjustment in any of the rights under the Warrants, the Corporation will:

(i) file with the Warrant Agent, a Certificate of the Corporation specifying the particulars of such event and, to the extent determinable, any adjustment required and the computation of such adjustment; and

(ii) deliver a certificate to the Warrantholders specifying the particulars of such event and, to the extent determinable, any adjustment required.

Such notice need only set forth such particulars as have been determined at the date such notice is given. If any adjustment for which such notice is given

is not then determinable, promptly after such adjustment is determinable the Corporation will:

(1) file with the Warrant Agent a Certificate of the Corporation showing the computation of such adjustment; and

(2) deliver a certificate to the Warrantholders of such adjustment.

The Warrant Agent may act and rely, for all purposes, upon the certificate and any other documents filed by the Corporation pursuant to this Section.

(n) Closing Transfer Books, etc. The Corporation will not close its transfer books or take any other corporate action which might deprive the holder of a Warrant of the opportunity of exercising its right of acquisition pursuant thereto during the period of ten Business Days after the giving of any notice required by Subsection 4.8(m).

(o) Protection of Warrant Agent. The Warrant Agent:

(i) shall not at any time be under any duty or responsibility to any Warrantholder to determine whether any facts exist which may require any adjustment in the Exercise Price, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed in making same;

(ii) shall not be accountable with respect to the validity or value (or the kind or amount) of any Warrant Shares or of any other shares, securities or property which may at any time be issued or delivered upon the exercise of any Warrant; and

(iii) shall not be responsible for any failure of the Corporation to make any cash payment or to issue, transfer or deliver Warrant Shares or share or warrant certificates upon the surrender of any Warrant for the purpose of exercise, or to comply with any of the covenants contained in this Section.

(p) Post-Adjustment. After any adjustment pursuant to this Section, the term “Warrant Shares” where used in this Indenture shall be interpreted to mean securities of any class or classes which, as a result of such adjustment and all prior adjustments pursuant to this Section, the Warrantholder is entitled to receive upon the exercise of its Warrants, and the number of Warrant Shares indicated in any exercise made pursuant to a Warrant shall be interpreted to mean the number of securities and other property and assets which, as a result of such adjustment and all prior adjustments pursuant to this Section 4.8, a Warrantholder is entitled to receive upon the exercise of a Warrant.

4.9 United States Securities Law Matters

(a) In connection with any exercise of Warrants, if it is required by law, the Corporation shall cause to be delivered to any U.S. Person or person in the United

States in whose name the Warrant Shares issuable upon exercise of the Warrants are to be issued a prospectus that complies with the U.S. Securities Act and that is a part of the Registration Statement that has been declared effective on or prior to the date hereof. For so long as any Warrants remain outstanding, the Corporation shall use its commercially reasonable efforts to (i) keep such Registration Statement continuously effective, and (ii) avoid the issuance of, or, if issued, obtain the withdrawal of any order enjoining or suspending the use or effectiveness of the Registration Statement or related prospectus or the lifting of any suspension of the qualification (or exemption from qualification) of any of the Warrants for sale in the United States, at the earliest practicable moment. All expenses incidental to the Corporation’s performance of or compliance with the foregoing provisions will be borne by the Corporation, including, without limitation: (i) all registration and filing fees and expenses; (ii) all fees and expenses of compliance with federal securities and state Blue Sky or securities laws; (iii) all fees and disbursements of counsel for the Corporation, independent certified public accountants of the Corporation and technical experts retained by the Corporation whose consent is required to be provided with respect to any Registration Statement.

(c) If any person shall fail to establish to the satisfaction of the Corporation or Warrant Agent the conditions described in Subsection 4.9(b), the holder of the applicable Warrant shall be notified by the Warrant Agent within three (3) Business Days that the evidence provided has been deemed insufficient to permit the exercise of such Warrant and providing a description of the nature of such deficiency. In the case where the Corporation is not satisfied with the provided evidence, it shall furnish to the Warrant Agent either (i) the form of proper notice to be delivered to establish the required evidence, or (ii) a description of the deficiency. Until such time as the Corporation or Warrant Agent, as the case may be, acting reasonably, is satisfied with the evidence provided, the holder of the Warrant shall not be permitted to exercise the Warrant.

(d) The Warrant Agent may assume that the Registration Statement remains effective until otherwise notified in writing by the Corporation that

such Registration Statement is no longer effective. The Corporation shall at all times be obligated to provide prompt notice to the Warrant Agent regarding any change in the effectiveness of any Registration Statement.

(c) In the event that any of the funds provided to the Warrant Agent hereunder are received by it in the form an uncertified cheque or bank draft, the Warrant Agent shall be entitled to delay the time for the release of such funds and the related Warrant Shares until such uncertified cheque has cleared the financial institution upon which the same is drawn.

9.9 Replacement of Warrant Agent

(a) Resignation. The Warrant Agent may resign its duties and obligations and be discharged from all further duties and liabilities hereunder, except as provided in this Section, by giving to the Corporation and the Warrantholders not less than 30 days’ notice in writing or, if a new Warrant Agent has been appointed, such shorter notice as the Corporation accepts as sufficient.

(b) Removal. The Warrantholders by Extraordinary Resolution may at any time remove the Warrant Agent and appoint a new warrant agent.

(c) Appointment of New Warrant Agent. If the Warrant Agent so resigns or is so removed or is dissolved, becomes bankrupt, goes into liquidation or otherwise becomes incapable of acting hereunder, the Corporation shall forthwith appoint a new warrant agent unless a new warrant agent has already been appointed by the Warrantholders.

(d) Failure to Appoint. Failing such appointment by the Corporation, the retiring Warrant Agent or any Warrantholder may apply at the expense of the Corporation to the Ontario Superior Court of Justice, on such notice as the Court directs, for the appointment of a new warrant agent.

(e) New Warrant Agent. Any new warrant agent appointed under this Section must be a corporation authorized to carry on the business of a transfer agent or trust company in Ontario and, if required by the Applicable Legislation of any other province, in such other province. On any such appointment the new warrant agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Warrant Agent without any further assurance, conveyance, act or deed, but there shall be immediately executed, at the expense of the Corporation, all such conveyances or other instruments as, in the opinion of counsel, are necessary or advisable for the purpose of assuring the transfer of such powers, rights, duties and responsibilities to the new warrant agent. Any new warrant agent so appointed by the Corporation or by the Court shall be subject to removal as aforesaid by the Warrantholders and by the Corporation.

(f) Notice of New Warrant Agent. On the appointment of a new warrant agent, the Corporation shall promptly give notice thereof to the Warrantholders in accordance with Subsection 10.2(a) hereof.

(g) Successor Warrant Agent. A corporation into or with which the Warrant Agent is merged or consolidated or amalgamated, or a corporation succeeding to the transfer agency or trust business of the Warrant Agent, shall be the successor to the Warrant Agent hereunder without any further act on its part or on the part of any party hereto if such corporation would be eligible for appointment as a new warrant agent under Subsection 9.9(e) hereof.

(h) Certificates. A Warrant Certificate certified but not delivered by a predecessor Warrant Agent may be delivered by the new or successor warrant agent in the name of the predecessor Warrant Agent or successor warrant agent.

(i) In case at any time the name of the Warrant Agent is changed and at such time any of the Warrant Certificates have been countersigned but not delivered, the Warrant Agent may adopt the countersignature under its prior name and deliver the Warrant Certificates so countersigned; and in case at that time any of the Warrant Certificates have not been countersigned, the Warrant Agent may countersign such Warrant Certificates either in its prior name or in its changed name; and in all such cases such Warrant Certificates will have the full force provided in the Warrant Certificates and in this Indenture.

9.10 Conflict of Interest

The Warrant Agent represents to the Corporation that at the time of the execution and delivery hereof no material conflict of interest exists between its role as an agent hereunder and its role in any other capacity and if a material conflict of interest arises hereafter it shall, within ten days after ascertaining that it has such material conflict of interest, either eliminate the conflict of interest or resign its duties hereunder. If any such material conflict of interest exists or hereafter shall exist, the validity and enforceability of this Indenture and the Warrants shall not be affected in any manner whatsoever by reason thereof.

9.11 Warrant Agent’s Authority to Carry on Business

The Warrant Agent represents to the Corporation that at the date hereof it is authorized to carry on business in the Province of Ontario. If, notwithstanding the provisions of this Section 9.11, the Warrant Agent ceases to be authorized to carry on such business, the validity and enforceability of this Indenture and the interest of the Warrantholders in the Warrants registered hereunder shall not be affected in any manner whatsoever by reason only of such event provided that the Warrant Agent, within 30 days after ceasing to be authorized to carry on business, either becomes so authorized or resigns in the manner and with the effects specified in Section 9.9.

9.12 Acceptance of Rights, Duties and Obligations

The Warrant Agent hereby accepts the rights, duties and obligations in this Warrant Indenture declared and provided for and agrees to perform them on the terms and conditions herein set forth.

9.13 Warrant Agent Not Bound to Act

The Warrant Agent shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Warrant Agent, in its sole judgment, determines that such act might cause it to be in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline. Further, should the Warrant Agent, in its sole judgment, determine at any time that its acting under this Indenture has resulted in it being in non-compliance with any applicable anti-money laundering or antiterrorist legislation, regulation or guideline, then it shall have the right to resign on ten (10) days’ written notice to the Corporation, or any shorter period of time as agreed to by the Corporation, notwithstanding the provisions of subsection 9.9(a) of this Indenture, provided (i) that the Warrant Agent’s written notice shall describe the circumstances of such non-compliance; and (ii) that if such circumstances are rectified to the Warrant Agent’s satisfaction within such ten (10) day period, then such resignation shall not be effective.

9.14 Privacy

The parties acknowledge that federal and/or provincial legislation that addresses the protection of individuals’ personal information (collectively, “Privacy Laws”) applies to obligations and activities under this Indenture. Despite any other provision of this Indenture, neither party shall take or direct any action that would contravene, or cause the other to contravene, applicable Privacy Laws. The Corporation shall, prior to transferring or causing to be transferred personal information to the Warrant Agent, obtain and retain required consents of the relevant individuals to the collection, use and disclosure of their personal information, or shall have determined that such consents either have previously been given upon which the parties can rely or are not required under the Privacy Laws. The Warrant Agent shall use commercially reasonable efforts to ensure that its services hereunder comply with Privacy Laws. Specifically, the Warrant Agent agrees:

(a) to have a designated chief privacy officer;

(b) to maintain policies and procedures to protect personal information and to receive and respond to any privacy complaint or inquiry;

(c) to use personal information solely for the purposes of providing its services under or ancillary to this Indenture and not to use it for any other purpose except with the consent of or direction from the Corporation or the individual involved;

(d) not to sell or otherwise improperly disclose personal information to any third party; and

(e) to employ administrative, physical and technological safeguards to reasonably secure and protect personal information against loss, theft, or unauthorized access, use or modification.

WARRANT CERTIFICATE

BANRO CORPORATION
(incorporated under the federal laws of Canada)

CERTIFICATE NUMBER		WARRANTS

	(each entitling the holder to acquire, subject to adjustment, one common share for each Warrant)

THIS IS TO CERTIFY that, for value received, [Insert name of holder here] (herein called the “Warrantholder” or “holder”) is the registered holder of the number of warrants (“Warrants”) specified above of Banro Corporation (the “Corporation”), each Warrant entitling the holder to subscribe for one fully paid and non-assessable common share (“Warrant Share”) of the Corporation upon payment of an exercise price of U.S.$2.20 per Warrant Share by way of certified cheque, electronic funds transfer, recognized bank draft or money order in lawful money of the United States payable to the order of the Corporation at any time on or before the Expiry Time (as hereinafter defined) on the basis, subject to adjustment, of one Warrant Share for each Warrant.

The Warrants represented by this certificate are issued under and pursuant to a certain warrant indenture (herein called the “Warrant Indenture”) dated September 17, 2008 between the Corporation and Equity Transfer & Trust Company, as warrant agent (“Warrant Agent”), to which Warrant Indenture and any instruments supplemental or ancillary thereto or in amendment thereof reference is hereby made for a full description of the rights of the holders of the Warrants and the terms and conditions upon which such Warrants are, or are to be, issued and held, all to the same effect as if the provisions of the Warrant Indenture and all instruments supplemental or ancillary thereto or in amendment thereof were herein set forth, to all of which provisions the holder of these Warrants by acceptance hereof assents.

Unless otherwise defined herein, all terms defined in the Warrant Indenture are used herein as so defined. In the event of any conflict or inconsistency between the provisions of the Warrant Indenture and the provisions of this Warrant Certificate, the provisions of the Warrant Indenture shall prevail. The Warrant Agent will furnish to the holder of this Warrant Certificate, upon request and upon payment of reasonable photocopying and delivery charges, a copy of the Warrant Indenture.

Exercise Period

The Warrants represented by this Warrant Certificate may be exercised by the holder (including, if applicable, any agent under any power of attorney granted by such holder) at any time during the period commencing on the date hereof and ending at 5:00 p.m. (Toronto time) on September 17, 2011 (the “Expiry Time”).

Effect of Exercise of Warrants

A Warrantholder may, at any time (and from time to time) at or prior to the Expiry Time, exercise all or any number of the then outstanding Warrants held by it, by surrendering this Warrant Certificate to the Warrant Agent at its office in Toronto, Ontario or to any other person or at any other place designated by the Corporation with the approval of the Warrant Agent, during normal business hours on a Business Day at such place, an “NCI letter of instruction” evidencing such Warrants, if applicable, and with a duly completed and executed notice of exercise in the form set forth herein.

Surrender of this Warrant Certificate will be deemed to have been effected only on personal delivery thereof to, or, if sent by mail or other means of transmission, on actual receipt thereof by, the Warrant Agent at its office in Toronto, Ontario or to such other person or at such other place as may be acceptable to the Warrant Agent.

Any notice of exercise in the form set forth herein must be signed by the Warrantholder, or his executors, administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Warrant Agent, acting reasonably, and, if any Warrant Shares thereby issuable are to be issued to a person or persons other than the Warrantholder, must specify the name or names and the address or addresses of each such person or persons and the number of Warrant Shares to be issued to each such person if more than one is so specified.

The holder may exercise less than all of the Warrants evidenced by this Warrant Certificate, in which event a new Warrant Certificate representing the Warrants not then exercised will be issued to the holder.

Upon the exercise of any Warrants, the Warrant Shares thereby issuable shall be deemed to have been issued, and the person or persons to whom such Warrant Shares are to be issued shall be deemed to have become the holder or holders of record thereof, on the day on which this Warrant Certificate is surrendered in accordance with the terms of the Warrant Indenture (the “Exercise Date”), unless the transfer registers for the Warrant Shares are closed on that date, in which case such Warrant Shares shall be deemed to have been issued and such person or persons shall be deemed to have become the holder or holders of record thereof on the date on which

A-ii

such transfer registers are reopened, but such Warrant Shares shall be issued on the basis of the number of Warrant Shares to which such person or persons were entitled on the Exercise Date.

Within three Business Days following the surrender to the Warrant Agent of the Warrant Certificates in accordance with the provisions of the Warrant Indenture, the Corporation shall, subject to certain exceptions, cause the Warrant Agent to mail to the person or persons in whose name or names the Warrant Shares thereby issued have been issued, at his or their respective addresses, or, if so specified, cause to be delivered to such person or persons at the place where the Warrant Certificates evidencing such Warrants were surrendered, certificates representing the Warrant Shares so issued.

If any Warrant Shares issuable pursuant to any Warrants are to be issued to a person or persons other than the Warrantholder, the Warrantholder must pay to the Corporation or to the Warrant Agent on its behalf an amount equal to all exigible transfer taxes or other government charges, and neither the Corporation nor the Warrant Agent will be required to issue or deliver any certificates representing any such Warrant Shares unless or until such amount has been so paid or the Warrantholder has established to the satisfaction of the Corporation that such taxes and charges have been paid or that no such taxes or charges are owing.

If at the time of exercise of the Warrants there remain trading restrictions on the Warrant Shares pursuant to applicable securities legislation, the Corporation or the Warrant Agent may, upon the advice of counsel, endorse any Warrant Share to such effect.

Pursuant to subsection 4.1(b) of the Indenture, if at any time following the initial effectiveness of a Registration Statement and the filing of the Supplement under the U.S. Securities Act and prior to the Expiry Date, the Corporation determines that such Registration Statement filed with the United States Securities and Exchange Commission is not effective, the Corporation shall promptly provide written notice of such determination to the Warrant Agent. Upon receipt of such notice, the Warrant Agent shall provide a copy thereof to each Warrantholder, and confirm in writing that the then outstanding Warrants may, until the earlier of the Registration Statement becoming effective and the Supplement having been filed or the Expiry Date, also be exercised by means of a “cashless exercise” in which the Warrantholder shall be entitled to receive a certificate for the number of Common Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

(a) A = the VWAP on the trading day immediately preceding the date of the receipt by the Warrant Agent of the notice of exercise;

(b) B = the Exercise Price of each Warrant, as adjusted; and

(c) X = the number of Warrant Shares issuable upon exercise of the Warrants in accordance with their terms by means of a cash exercise rather than a cashless exercise.

Warrants Void After Expiry Time

After the Expiry Time, no holder of a Warrant Certificate representing a Warrant which has not been validly exercised has any rights either under the Warrant Indenture or the Warrant Certificate, and the Warrants are void and of no value or effect. No holder of a Warrant

A-iii

Certificate will receive any notice from the Warrant Agent notifying the holder thereof of the expiry date of the Warrant.

Other Provisions

The Corporation shall not be required to issue any fractional Warrant Shares in satisfaction of its obligations pursuant to the Warrant Indenture and no cash or other consideration will be paid in lieu of fractional shares. Any subscription for fractional Warrant Shares will be deemed to be a subscription for the next largest whole number of Warrant Shares.

No Warrant Shares will be issued pursuant to any exercise of any Warrant if the issue of such security would constitute a violation of the securities laws of any applicable jurisdiction.

The Warrant Indenture provides for adjustments to the rights of the holders of Warrants, including the number of Warrant Shares issuable upon the exercise thereof, on the happening of certain stated events, including the subdivision or consolidation of the outstanding Common Shares of the Corporation, certain distributions of Common Shares of the Corporation, or of securities convertible into or exchangeable for Common Shares or of other securities or assets of the Corporation, certain offerings of rights, warrants or options and certain capital reorganizations.

The Warrant Indenture contains provisions making binding on all holders of Warrants outstanding thereunder resolutions passed at meetings of such holders held in accordance with such provisions and instruments in writing signed by holders of a specified majority of all outstanding Warrants.

On presentation at the office of the Warrant Agent in Toronto, Ontario, subject to the provisions of the Warrant Indenture and on compliance with the reasonable requirements of the Warrant Agent, one or more Warrant Certificates may be exchanged to the holder for one or more Warrant Certificates of different denominations, bearing the same legends, evidencing in the aggregate the same number of Warrants as the Warrant Certificate or Warrant Certificates being exchanged.

The Warrants evidenced by this Warrant Certificate may only be transferred upon compliance with the conditions prescribed in the Warrant Indenture, on the register of transfers to be kept at the office of the Warrant Agent in Toronto, Ontario, by the holder or his executors, administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Warrant Agent and, upon compliance with such requirements and such other reasonable requirements as the Warrant Agent and the Corporation may prescribe, such transfer will be recorded on such register of transfers by the Warrant Agent. Notwithstanding the foregoing, the Corporation will be entitled, and may direct the Warrant Agent, to refuse to record any transfer of any Warrant on such register if such transfer would constitute a violation of the securities laws of any jurisdiction.

The holding of this Warrant Certificate will not constitute the holder a shareholder of the Corporation or entitle such holder to any right or interest in respect thereof except as otherwise provided in the Warrant Indenture.

A-iv

This Warrant Certificate will not be valid for any purpose until it has been certified by or on behalf of the Warrant Agent for the time being under the Warrant Indenture.

Time is of the essence hereof.

This Warrant Certificate will be construed in accordance with the laws of the Province of Ontario and of Canada applicable therein and will be treated in all respects as an Ontario contract.

To exercise your rights hereunder, please complete and execute the notice of exercise set out on the back of this Warrant Certificate and deliver it and this Warrant Certificate to the Warrant Agent.

The Corporation shall be entitled, and may direct the Warrant Agent, to refuse to recognize any transfer, or enter the name of any transferee, of any Warrant, if such transfer would constitute a violation of the securities laws of any jurisdiction or the rules, regulations or policies of any regulatory authority having jurisdiction. Compliance with the securities law of any jurisdiction is the responsibility of the holder of Warrants or its transferee.

IN WITNESS WHEREOF THE CORPORATION has caused this Warrant Certificate to be signed by its officer or other individual authorized in that behalf as of September ·, 2008.
