(c) a Warrantholder shall have the option to exercise its Warrants in accordance with the terms of this Warrant Indenture within the 30-day period after the deemed receipt of the Acceleration Notice.

The signature of any such director or officer may be mechanically reproduced in facsimile or other electronic format and Warrant Certificates bearing such facsimile or other electronic format signatures shall be binding upon the Company as if they had been manually signed by such director or officer. Notwithstanding that the person whose manual or electronic signature appears on any Warrant Certificate as a director or officer may no longer hold office at the Issue Date of the Warrant Certificate or at the date of certification or delivery thereof, any Warrant Certificate signed as aforesaid shall, subject to section 2.4, be valid and binding upon the Company and the registered holder thereof will be entitled to the benefits of this Indenture.

2.4 Authentication or Certification by the Warrant Agent

(2) The applicant for the issue of a new Warrant Certificate pursuant to this section 2.6 shall bear the cost of the issue thereof and in the case of mutilation shall, as a condition precedent to the issue thereof, deliver to the Warrant Agent the mutilated Warrant Certificate, and in the case of loss, destruction or theft shall, as a condition precedent to the issue thereof, furnish to the Company and to the Warrant Agent such evidence of ownership and of the loss, destruction or theft of the Warrant Certificate so lost, destroyed or stolen as shall be satisfactory to the Company and to the Warrant Agent in their sole discretion and such applicant may be required to furnish an indemnity and surety bond in amount and form satisfactory to the Company and the Warrant Agent in their sole discretion and shall pay the reasonable charges of the Company and the Warrant Agent in connection therewith.

(b) a register of transfers in which all transfers of Warrants and the date and other particulars of each such transfer shall be entered.

(2) No transfer of any Warrant will be valid unless entered on the register of transfers referred to in subsection 2.8(1), upon surrender to the Warrant Agent of the Warrant Certificate evidencing such Warrant, and a duly completed and executed transfer form endorsed on the Warrant Certificate executed by the registered holder or his executors, administrators or other legal representatives or his attorney duly appointed by an instrument in writing in form and execution satisfactory to the Warrant Agent, if applicable, and, upon compliance with such requirements and such other reasonable requirements as the Warrant Agent may prescribe, such transfer will be recorded on the register of transfers by the Warrant Agent.

(3) The transferee of any Warrant will, after surrender to the Warrant Agent of the Warrant as required by subsection 2.8(2) and upon compliance with all other conditions in respect thereof required by this Indenture or by law, be entitled to be entered on the register of holders referred to in subsection 2.8(1) as the owner of such Warrant free from all equities or rights of set-off or counterclaim between the Company and the transferor or any previous holder of such Warrant, except in respect of equities of which the Company is required to take notice by statute or by order of a court of competent jurisdiction.

(4) The Company 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 2.8(1), if such transfer would constitute a violation of the Securities Laws of any applicable jurisdiction or the rules, regulations or policies of any regulatory authority having jurisdiction or the representations and warranties made by the Warrantholder in the United States pursuant to the Private Placement under which the Warrants were acquired. The Warrant Agent is entitled to assume compliance with all applicable Securities Laws unless otherwise notified in writing by the Company. No duty shall rest with the Warrant Agent to determine compliance of the transferee or transferor of any Warrant with applicable Securities Laws.

(5) Any Warrant issued to a transferee upon transfers contemplated by this section 2.8 shall bear the appropriate legend(s) as set forth in subsections 2.21(1), (2) and 2.22(2), if applicable.

(6) If a Warrant tendered for transfer bears the legend set forth in subsection 2.22(2), the Warrant Agent shall not register such transfer unless the transferor has provided the Warrant Agent with the Warrant Certificate and complies with the requirements of the said subsection 2.22(2).

(7) Warrants, in certificated form, bearing the legend set forth in subsection 2.22(2) shall not be offered, sold or otherwise transferred except (A) to the Company, (B) outside the United States in accordance with Rule 904 of Regulation S under the U.S. Securities Act and in compliance with applicable local laws and regulations, (C) within the United States in accordance with (i) Rule 144A under the U.S. Securities Act or (ii) Rule 144 under the U.S. Securities Act, if available, and in compliance with applicable state securities laws, or (D) in another transaction that does not require registration under the U.S. Securities Act or any applicable state securities laws, provided that in the case of transfers pursuant to (C)(ii) or (D) above, the Company has received an opinion of counsel satisfactory to it to such effect, and, in each case, in accordance with applicable state securities laws. Warrants, in uncertificated form, held by a Warrantholder in the United States or a U.S. Person may be offered, sold or otherwise transferred only in accordance with this section 2.8(7) (A) or (B).

2.9 Registers Open for Inspection

The registers referred to in subsection 2.8(1) shall be open at all reasonable times during business hours on a Business Day for inspection by the Company or any Warrantholder. The Warrant Agent shall, from time to time when requested to do so in writing by the Company, furnish the Company with a list of the names and addresses of holders of Warrants entered in the register of holders kept by the Warrant Agent and showing the number of Warrants held by each such holder.

2.10 Exchange of Warrants

(1) Warrants may, upon compliance with the reasonable requirements of the Warrant Agent, be exchanged for Warrants in any other authorized denomination representing in the aggregate an equal number of Warrants as the number of Warrants represented by the Warrants being exchanged. The Company shall sign and the Warrant Agent shall Authenticate or certify, in accordance with sections 2.3 and 2.4, all Warrants necessary to carry out the exchanges contemplated herein.

(2) Warrants may be exchanged only at the principal stock transfer offices of the Warrant Agent in the City of Toronto, Ontario or at any other place that is designated by the Company with the approval of the Warrant Agent. Any Warrants tendered for exchange shall be surrendered to the Warrant Agent and cancelled.

(3) Except as otherwise herein provided, the Warrant Agent may charge Warrantholders requesting an exchange a reasonable sum for each Warrant Certificate issued; and payment of such charges and reimbursement of the Warrant Agent or the Company 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.

2.11 Ownership of Warrants

The Company and the Warrant Agent and their respective agents may deem and treat the registered holder of any Warrant as the absolute owner of the Warrant represented thereby for all purposes and the Company and the Warrant Agent and their respective agents shall not be affected by any notice or knowledge to the contrary except as required by statute or order of a court of competent jurisdiction. The holder of any Warrant shall be entitled to the rights evidenced by that Warrant free from all equities or rights of set-off or counterclaim between the Company and the original or any intermediate holder thereof and all persons may act accordingly and the receipt by any holder of the Warrant Shares or monies obtainable pursuant to the exercise of the Warrant shall be a good discharge to the Company and the Warrant Agent for the same and neither the Company nor the Warrant Agent shall be bound to inquire into the title of any holder.

2.12 Uncertificated Warrants

(1) Registration and re-registration of beneficial interests in and transfers of Warrants held by CDS shall be made only through the Book-Entry Only System and no Warrant Certificates shall be issued in respect of such Warrants except where physical certificates evidencing ownership in such securities are required or as set out herein or as may be requested by CDS, as determined by the Company, from time to time. Except as provided in this section 2.12, owners of beneficial interests in any Uncertificated Warrants shall not be entitled to have Warrants registered in their names and shall not receive or be entitled to receive Warrants in definitive form or to have their names appear in the register referred to in section 2.8 herein. Notwithstanding any terms set out herein, Warrants subject to the restrictions and any legend set forth in section 2.21 or 2.22, as applicable, herein and held in the name of CDS may only be held in the form of Uncertificated Warrants with the prior consent of the Company and CDS.

(2) If any Warrant is issued in uncertificated form and any of the following events occurs:

(a) CDS or the Company has notified the Warrant Agent that (A) CDS is unwilling or unable to continue as depository or (B) CDS ceases to be a clearing agency in good standing under applicable laws and, in either case, the Company is unable to locate a qualified successor depository within 90 days of delivery of such notice;

(b) the Company has determined, in its sole discretion, with the consent of the Warrant Agent, to terminate the Book-Entry Only System in respect of such Uncertificated Warrants and has communicated such determination to the Warrant Agent in writing;

(d) the Book-Entry Only System administered by CDS ceases to exist,

then one or more definitive fully registered Warrant Certificates shall be executed by the Company and certified and delivered by the Warrant Agent to CDS in exchange for the Uncertificated Warrants form held by CDS.

Fully registered Warrant Certificates issued and exchanged pursuant to this subsection shall be registered in such names and in such denominations as CDS shall instruct the Warrant Agent, provided that the aggregate number of Warrants represented by such Warrant Certificates shall be equal to the aggregate number of Uncertificated Warrants so exchanged. Upon exchange of Uncertificated Warrants for one or more Warrant Certificates in definitive form, such Uncertificated Warrants shall be cancelled by the Warrant Agent.

(3) Subject to the provisions of this section 2.12, any exchange of Warrants for Warrants which are not Uncertificated Warrants may be made in whole or in part in accordance with the provisions of section 2.10, mutatis mutandis. All such Warrants issued in exchange for Uncertificated Warrants or any portion thereof shall be registered in such names as CDS for such Uncertificated Warrants shall direct and shall be entitled to the same benefits and subject to the same terms and conditions (except insofar as they relate specifically to Warrants) as the Warrants or portion thereof surrendered upon such exchange.

(4) Every Warrant Authenticated upon registration of transfer of Warrants, or in exchange for or in lieu of Uncertificated Warrants or any portion thereof, whether pursuant to this section 2.12, or otherwise, shall be Authenticated in the form of, and shall be, an Uncertificated Warrant, unless such Warrant is registered in the name of a person other than CDS for such Uncertificated Warrant or a nominee thereof.

(5) Notwithstanding anything to the contrary in this Indenture, subject to Applicable Legislation, the Uncertificated Warrants will be issued as an Uncertificated Warrant, unless otherwise requested in writing by CDS or the Company.

(6) The rights of beneficial owners of Warrants who hold securities entitlements in respect of the Warrants through the Book-Entry Only System shall be limited to those established by applicable law and agreements between CDS and the Participants and between such Participants and the beneficial owners of Warrants who hold securities entitlements in respect of the Warrants through the Book-Entry Only System, and such rights must be exercised through a Participant in accordance with the rules and procedures of CDS.

(7) Notwithstanding anything herein to the contrary, neither the Company nor the Warrant Agent nor any agent thereof shall have any responsibility or liability for:

(a) the electronic records maintained by CDS relating to any ownership interests or any other interests in the Warrants or the depository system maintained by CDS, or payments made on account of any ownership interest or any other interest of any person in any Warrant represented by an electronic position in the Book-Entry Only System (other than CDS or its nominee);

(b) maintaining, supervising or reviewing any records of CDS or any Participant relating to any such interest; or

(c) any advice or representation made or given by CDS or those contained herein that relate to the rules and regulations of CDS or any action to be taken by CDS on its own direction or at the direction of any Participant.

(8) The Company may terminate the application of this section 2.12 in its sole discretion in which case all Warrants shall be evidenced by Warrant Certificates registered in the name of a person other than CDS.

2.13 Adjustment of Exchange Basis

Subject to section 2.14, the Exchange Basis shall be subject to adjustment from time to time in the events and in the manner provided as follows:

(1) If and whenever, at any time after the date hereof and prior to the Time of Expiry, the Company shall:

(i) issue Common Shares or securities exchangeable for or convertible into Common Shares to all or substantially all the holders of the Common Shares as a stock dividend or other distribution (other than as a Dividend Paid in the Ordinary Course or a distribution of Warrant Shares upon exercise of the Warrants or pursuant to the exercise of incentive stock options granted under stock option plans of the Company), or

(ii) subdivide, redivide or change its then outstanding Common Shares into a greater number of Common Shares, or

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

(any of such events in these paragraphs (i), (ii) or (iii) being called a "Common Share Reorganization"), then the Exchange Basis in effect on the effective date of such subdivision or consolidation, or on the record date of such stock dividend or other distribution, as the case may be, shall be adjusted by multiplying the Exchange Basis in effect immediately prior to such effective or record date by a fraction:

(a) the numerator of which shall be the total number of Common Shares outstanding on such date immediately after giving effect to such Common Share Reorganization (including, in the case where securities exchangeable for or convertible into Common Shares are distributed, the number of Common Shares that would have been outstanding had such securities been exchanged for or converted into Common Shares on such record date, assuming in any case where such securities are not then convertible or exchangeable but subsequently become so, that they were convertible or exchangeable on the record date on the basis upon which they first become convertible or exchangeable), and

(b) the denominator of which shall be the total number of Common Shares outstanding on such date before giving effect to such Common Share Reorganization. The resulting product, adjusted to the nearest 1/100th, shall thereafter be the Exchange Basis until further adjusted as provided in this Article 2.

To the extent that any adjustment in the Exchange Basis occurs pursuant to this subsection 2.13(1) as a result of the fixing by the Company of a record date for the distribution of securities exchangeable for or convertible into Common Shares and the Common Share Reorganization does not occur or any conversion or exchange rights are not fully exercised, the Exchange Basis shall be readjusted immediately after the expiry of any relevant exchange or conversion right or the termination of the Common Share Reorganization, as the case may be, to the Exchange Basis that would then be in effect, based upon the number of Common Shares actually issued and remaining issuable after such expiry and shall be further readjusted in such manner upon the expiry of any further such right.

(2) If and whenever, at any time after the date hereof and prior to the Time of Expiry, the Company shall fix a record date for the distribution to all or substantially all of the holders of its outstanding Common Shares of rights, options or warrants entitling them, for a period expiring not more than 45 days after such record date, to subscribe for or purchase Common Shares, or securities exchangeable for or convertible into Common Shares, at a price per share to the holder (or at an exchange or conversion price per share) of less than 95% of the Current Market Price on such record date (any of such events being called a "Rights Offering"), then the Exchange Basis shall be adjusted effective immediately after such record date for the Rights Offering by multiplying the Exchange Basis in effect immediately prior to such record date by a fraction:

(a) the numerator of which shall be the number of Common Shares which would be outstanding after giving effect to the Rights Offering (assuming the exercise of all of the rights, options or warrants under the Rights Offering and assuming the exchange or conversion into Common Shares of all exchangeable or convertible securities issued upon exercise of such rights, options or warrants, if any), and

(b) the denominator of which shall be the aggregate of:

(i) the total number of Common Shares outstanding as of the record date for the Rights Offering, and

(ii) a number of Common Shares determined by dividing

(A) the amount equal to the aggregate consideration payable on the exercise of all of the rights, options and warrants under the Rights Offering plus the aggregate consideration, if any, payable on the exchange or conversion of the exchangeable or convertible securities issued upon exercise of such rights, options or warrants (assuming the exercise of all rights, options and warrants under the Rights Offering and assuming the exchange or conversion of all exchangeable or convertible securities issued upon exercise of such rights, options and warrants);

(B) the Current Market Price as of the record date for the Rights Offering.

The resulting product, adjusted to the nearest 1/100th, shall thereafter be the Exchange Basis until further adjusted as provided in this Article 2. Any Common Shares owned by or held for the account of the Company or any of its Subsidiaries or a partnership in which the Company is directly or indirectly a party to will be deemed not to be outstanding for the purpose of any computation. If, at the date of expiry of the rights, options or warrants subject to the Rights Offering, less than all the rights, options or warrants have been exercised, then the Exchange Basis shall be readjusted effective immediately after the date of expiry to the Exchange Basis which would have been in effect on the date of expiry if only the rights, options or warrants issued had been those exercised. If at the date of expiry of the rights of exchange or conversion of any securities issued pursuant to the Rights Offering less than all of such securities have been exchanged or converted into Common Shares, then the Exchange Basis shall be readjusted effective immediately after the date of expiry to the Exchange Basis which would have been in effect on the date of expiry if only the exchangeable or convertible securities issued had been those securities actually exchanged for or converted into Common Shares.

(3) If and whenever, at any time after the date hereof and prior to the Time of Expiry, the Company shall fix a record date for the issuance or distribution to all or substantially all the holders of its outstanding Common Shares of:

(i) shares of the Company of any class other than Common Shares; or

(ii) rights, options or warrants to acquire Common Shares or securities exchangeable for or convertible into Common Shares; or

(iii) evidences of indebtedness; or

(iv) cash, securities or any property or other assets,

and if such issuance or distribution does not constitute a Dividend Paid in the Ordinary Course, a Common Share Reorganization or a Rights Offering (any of such non-excluded events being herein called a "Special Distribution"), the Exchange Basis shall be adjusted effective immediately after the record date for the Special Distribution by multiplying the Exchange Basis in effect on such record date by a fraction:

(a) the numerator of which shall be the number of Common Shares outstanding on such record date multiplied by the Current Market Price on such record date, and

(b) the denominator of which shall be:

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

(B) the fair market value, as determined by action by the board of directors acting reasonably and in good faith (whose determination shall be conclusive), to the holders of the Common Shares of the shares, rights, options, warrants, evidences of indebtedness or property or other assets issued or distributed in the Special Distribution,

provided that no such adjustment shall be made if the result of such adjustment would be to decrease the Exchange Basis in effect immediately before such record date. The resulting product, adjusted to the nearest 1/100th, shall thereafter be the Exchange Basis until further adjusted as provided in this Article 2. Any shares owned by or held for the account of the Company or its Subsidiaries or a partnership of which the Company is directly or indirectly a party to shall be deemed not to be outstanding for the purpose of any such computation.

(4) If and whenever, at any time after the date hereof and prior to the Time of Expiry, there shall be a reclassification of the Common Shares at any time outstanding or change or exchange of the Common Shares into other shares or into other securities (other than a Common Share Reorganization), or a consolidation, amalgamation, plan of arrangement or merger of the Company with or into any other corporation or other entity (other than a consolidation, amalgamation, plan of arrangement or merger which does not result in any reclassification of the outstanding Common Shares or a change of the Common Shares into other shares), or a transfer (other than to a Subsidiary) of the undertaking or assets of the Company as an entirety or substantially as an entirety to another corporation or other entity (any of such events being herein called a "Capital Reorganization"), any Warrantholder who thereafter shall exercise his right to receive Warrant Shares pursuant to Warrant(s) shall be entitled to receive, and shall accept 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 resulting from the Capital Reorganization which such holder would have been entitled to receive as a result of such Capital Reorganization if, on the effective date or record date thereof, as the case may be, the Warrantholder had been the registered holder of the number of Warrant Shares to which such holder was theretofore entitled upon exercise. If appropriate, adjustments shall be made as a result of any such Capital Reorganization in the application of the provisions set forth in this Article 2 with respect to the rights and interests thereafter of Warrantholders to the end that the provisions set forth in this Article 2 shall thereafter correspondingly be made applicable as nearly as may reasonably be in relation to any shares, other securities or other property thereafter deliverable upon the exercise of any Warrant. Any such adjustment shall be made by and set forth in an indenture supplemental hereto approved by the directors and by the Warrant Agent and entered into pursuant to the provisions of this Indenture and shall for all purposes be conclusively deemed to be an appropriate adjustment.

(5) Any adjustment to the Exchange Basis as set forth herein shall also include a corresponding adjustment to the Exercise Price which shall be calculated by multiplying the Exercise Price by a fraction: (a) the numerator of which shall be the Exchange Basis prior to the adjustment, and (b) the denominator of which shall be the Exchange Basis after the adjustment.

2.14 Rules Regarding Calculation of Adjustment of Exchange Basis

For the purposes of section 2.13:

(1) The adjustments provided for in section 2.13 shall be cumulative and such adjustments shall be made successively whenever an event referred to in section 2.13 shall occur, subject to the following subsections of this section 2.14.

(2) No adjustment in the: (a) Exchange Basis shall be required unless such adjustment would result in a change of at least 0.01 of a Warrant Share based on the prevailing Exchange Basis; or (b) Exercise Price shall be required unless such adjustment would result in a change of at least 1%, provided that any adjustments which, except for the provisions of this subsection, would otherwise have been required to be made, shall be carried forward and taken into account in any subsequent adjustment.

(3) No adjustment in the Exchange Basis shall be made in respect of any event described in section 2.13, other than the events referred to in paragraphs (ii) and (iii) of subsection (1) thereof, if Warrantholders are entitled to participate in such event on the same terms, mutatis mutandis, as if Warrantholders had exercised their Warrants prior to or on the effective date or record date of such event, any such participation being subject to regulatory approval.

(4) No adjustment in the Exchange Basis shall be made pursuant to section 2.13 in respect of the issue from time to time of Warrant Shares purchasable on exercise of the Warrants or in respect of the issue from time to time of a Dividend Paid in the Ordinary Course to holders of Common Shares who exercise an option or election to receive substantially equivalent dividends in Common Shares in lieu of receiving a cash dividend, and any such issue shall be deemed not to be a Common Share Reorganization.

(5) If a dispute shall at any time arise with respect to adjustments provided for in section 2.13, such dispute shall, absent manifest error, 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 the directors and any further determination, absent manifest error, shall be binding upon the Company, the Warrant Agent and the Warrantholders.

(6) If the Company shall set a record date to determine the holders of the Common Shares for the purpose of entitling them to receive any dividend or distribution or any subscription or purchase rights 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 Exchange Basis shall be required by reason of the setting of such record date.

(7) In the absence of a resolution of the directors fixing a record date for a Rights Offering or Special Distribution, the Company shall be deemed to have fixed as the record date therefor the date on which the Rights Offering or Special Distribution is effected.

(8) If the purchase price provided for in any Rights Offering (the "Rights Offering Price") is decreased, the Exchange Basis shall forthwith be changed so as to increase the Exchange Basis to such Exchange Basis as would have been obtained had the adjustment to the Exchange Basis made pursuant to subsection 2.13(2) upon the issuance of such Rights Offering been made upon the basis of the Rights Offering Price as so decreased, provided that the provisions of this subsection shall not apply to any decrease in the Rights Offering Price resulting from provisions in any such Rights Offering designed to prevent dilution if the event giving rise to such decrease in the Rights Offering Price itself requires an adjustment to the Exchange Basis pursuant to the provisions of section 2.13.

(9) As a condition precedent to the taking of any action that would require any adjustment in any of the subscription rights pursuant to any of the Warrants, including the Exchange Basis, the Company shall take any corporate action which may, in the opinion of counsel, be necessary in order that the Company have unissued and reserved in its authorized capital and may validly and legally issue as fully paid and non-assessable all the shares or other securities that all the holders of such Warrants are entitled to receive on the exercise of all the subscription rights attaching thereto in accordance with the provisions thereof.

(10) In case the Company, after the date hereof, shall take any action affecting any Common Shares, other than action described in section 2.13, which in the opinion of the directors acting reasonably and in good faith would materially affect the rights of Warrantholders, the Exchange Basis shall be adjusted in such manner, if any, and at such time, as the directors, in their sole discretion acting in good faith, may determine to be equitable in the circumstances. Failure of the taking of action by the directors so as to provide for an adjustment in the Exchange Basis prior to the effective date of any action by the Company affecting the Common Shares shall be conclusive evidence that the directors have determined that it is equitable to make no adjustment in the circumstances.

(11) The Warrant Agent shall be entitled to act and rely on any adjustment calculations by the Company or the Company's Auditors.

2.15 Postponement of Subscription

In any case where the application of section 2.13 results in an increase in the number of Common Shares that are issuable upon exercise of the Warrants taking effect immediately after the record date for a specific event, if any Warrant is exercised after that record date and prior to completion of such specific event, the Company may postpone the issuance to the Warrantholder of the Warrant Shares to which he is entitled by reason of such adjustment, but such Warrant Shares shall be so issued and delivered to that holder upon completion of that event, with the number of such Warrant Shares calculated on the basis of the number of Warrant Shares on the date that the Warrant was exercised, adjusted for completion of that event and the Company shall deliver to the person or persons in whose name or names the Warrant Shares are to be issued an appropriate instrument evidencing the right of such person or persons to receive such Warrant Shares and the right to receive any dividends or other distributions which, but for the provisions of this section 2.15, such person or persons would have been entitled to receive in respect of such Warrant Shares from and after the date that the Warrant was exercised in respect thereof.

2.16 Notice of Adjustment

(1) At least 14 days prior to the effective date or record date, as the case may be, of any event which requires or might require adjustment pursuant to section 2.13, the Company shall:

(a) file with the Warrant Agent a certificate of the Company specifying the particulars of such event (including the record date or the effective date for such event) and, if determinable, the required adjustment and the computation of such adjustment; and

(b) give notice to the Warrantholders of the particulars of such event (including the record date or the effective date for such event) and, if determinable, the required adjustment.

(2) In case any adjustment for which a notice in subsection 2.16(1) has been given is not then determinable, the Company shall promptly after such adjustment is determinable:

(a) file with the Warrant Agent a computation of such adjustment; and

(b) give notice to the Warrantholders of the adjustment.

(3) The Warrant Agent may, absent manifest error, act and rely upon certificates and other documents filed by the Company pursuant to this section 2.16 for all purposes of the adjustment.

2.17 No Action after Notice

The Company covenants with the Warrant Agent that it will not take any other corporate action which might deprive a Warrantholder of the opportunity of exercising the rights of acquisition pursuant thereto during the period of 10 days after the giving of the notice set forth in paragraph (b) of subsections 2.16(1) and (2).

2.18 Purchase of Warrants for Cancellation

The Company may, at any time and from time to time, purchase Warrants by invitation for tender, by private contract or otherwise (which shall include a purchase through an investment dealer or firm holding membership on a Canadian stock exchange) on such terms as the Company may determine. All Warrants purchased pursuant to the provisions of this section 2.18 shall be forthwith delivered to, cancelled and destroyed by the Warrant Agent and shall not be reissued. If required by the Company, the Warrant Agent shall furnish the Company with a certificate as to such destruction.

2.19 Optional Purchases by the Company

Subject to applicable law and prior approval of the TSXV, if required, the Company may from time to time purchase on any stock exchange (if then listed), in the open market, by private agreement or otherwise any of the Warrants. Any such purchase shall be made at the lowest price or prices at which, in the opinion of the board of directors of the Company, such Warrants are then obtainable, plus reasonable costs of purchase, and may be made in such manner, from such persons, and on such other terms as the Company in its sole discretion may determine. The Warrant Certificates representing the Warrants purchased pursuant to this section 2.19 shall forthwith be delivered to, cancelled and destroyed by the Warrant Agent.

2.20 Protection of Warrant Agent

Subject to Article 8, the Warrant Agent shall not:

(a) at any time be under any duty or responsibility to any registered holder of Warrants to determine whether any facts exist that may require any adjustment contemplated by this Article 2, nor to verify the nature and extent of any such adjustment when made or the method employed in making the same;

(b) be accountable with respect to the validity or value or the kind or amount of any Warrant Shares that may at any time be issued or delivered upon the exercise of the Warrants;

(c) be responsible for any failure of the Company to make any cash payment upon the surrender of any Warrants for the purpose of the exercise of such rights or to comply with any of the covenants contained in this Article 2; or

(d) incur any liability or responsibility whatsoever or be in any way responsible for the consequence of any breach on the part of the Company of any of the representations, warranties or covenants of the Company or any acts or deeds of the agents or servants of the Company.

provided that, if any Warrants or Warrant Shares issuable upon exercise of the Warrants are being sold in accordance with Rule 904 of Regulation S, the legend may be removed by providing to the Warrant Agent or the Transfer Agent, as applicable, (i) a declaration in the form attached hereto as Schedule "B" (or as the Company may prescribe from time to time in order to address changes in applicable laws) and (ii) if required by the Warrant Agent or the Transfer Agent, as applicable, an opinion of counsel, of recognized standing reasonably satisfactory to the Company, or other evidence reasonably satisfactory to the Company, that the proposed transfer may be effected without registration under the U.S. Securities Act;

and provided, further, that, if any Warrants or Warrant Shares issuable upon exercise of the Warrants are being sold under Rule 144, the legend may be removed by delivering to the Warrant Agent or the Transfer Agent, as applicable, an opinion of counsel of recognized standing reasonably satisfactory to the Company, that the legend is no longer required under applicable requirements of the U.S. Securities Act or state securities laws;

(3) If a Warrant or Warrant Share issued with respect to an exercise of Warrants is tendered for transfer and bears the legend set forth in subsection 2.22(2) herein and the holder thereof has not obtained the prior written consent of the Company, the Warrant Agent or the Transfer Agent, as the case may be, shall not register such transfer unless the holder complies with the requirements of the said subsection 2.22(2) hereof.

ARTICLE 3 - EXERCISE OF WARRANTS

3.1 Method of Exercise of Warrants

(1) The registered Warrantholder may exercise the rights thereby conferred on them to acquire all or any part of the Warrant Shares to which such Warrant entitles the holder, by surrendering the Warrant Certificate representing such Warrants to the Warrant Agent at any time prior to the Time of Expiry at its principal stock transfer offices in the City of Toronto, Ontario (or at such additional place or places as may be decided by the Company from time to time with the approval of the Warrant Agent), with a duly completed and executed exercise form of the registered holder or his executors, administrators or other legal representative or his attorney duly appointed by an instrument in writing in the form and manner satisfactory to the Warrant Agent, substantially in the form endorsed on the Warrant Certificate specifying the number of Warrant Shares subscribed for together with a certified cheque, bank draft or money order in lawful money of Canada, payable to or to the order of the Company in an amount equal to the Exercise Price multiplied by the number of Warrant Shares subscribed for. A Warrant Certificate with the duly completed and executed exercise form and payment of the Exercise Price shall be deemed to be surrendered only upon personal delivery thereof to or, if sent by mail or other means of transmission, upon actual receipt thereof by the Warrant Agent.

(2) Any exercise form referred to in subsection 3.1(1) shall be signed by the Warrantholder, or his executors, or administrators or other legal representative or his attorney duly appointed by an instrument in writing in the form and manner satisfactory to the Warrant Agent, shall specify the person(s) in whose name such Warrant Shares are to be issued, the address(es) of such person(s) and the number of Warrant Shares to be issued to each person, if more than one is so specified. If any of the Warrant Shares subscribed for are to be issued to (a) person(s) other than the Warrantholder, the signatures set out in the exercise form referred to in subsection 3.1(1) shall be guaranteed by a Canadian Schedule 1 chartered bank or a medallion signature guarantee from a member of a recognized Signature Medallion Guarantee Program and the Warrantholder shall pay to the Company or the Warrant Agent all applicable transfer or similar taxes and the Company shall not be required to issue or deliver certificates evidencing Warrant Shares unless or until such Warrantholder shall have paid to the Company or the Warrant Agent on behalf of the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid or that no tax is due.

(3) If, at the time of exercise of the Warrants, in accordance with the provisions of subsection 3.1(1), there are any trading restrictions on the Warrant Shares pursuant to applicable securities legislation or stock exchange requirements, the Company shall, on the advice of counsel, endorse any certificates representing the Warrant Shares to such effect. The Warrant Agent is entitled to assume compliance with all applicable securities legislation unless otherwise notified in writing by the Company.

(4) A Beneficial Owner who desires to exercise his Uncertificated Warrants, must do so by causing a Participant to deliver to CDS (at its office in the City of Toronto), on behalf of the Beneficial Owner at any time prior to the Time of Expiry, a written notice of the Beneficial Owner's intention to exercise Warrants (the "Exercise Notice"). Forthwith upon receipt by CDS of such notice, as well as payment for the Exercise Price, CDS shall deliver to the Warrant Agent confirmation of its intention to exercise Warrants (the "Confirmation") in a manner acceptable to the Warrant Agent, including by electronic means through the Book-Entry Only System. CDS will initiate the exercise by way of the Confirmation and forward the aggregate Exercise Price electronically to the Warrant Agent and the Warrant Agent will execute the exercise by issuing to CDS through the Book-Entry Only System the Warrant Shares to which the exercising Beneficial Owner is entitled pursuant to the exercise. Any expense associated with the preparation and delivery of Exercise Notices will be for the account of the Beneficial Owner exercising the Warrants.

(5) An electronic exercise of the Uncertificated Warrants initiated by the Book-Entry Only Participant through the Book-Entry Only System shall constitute a representation to both the Company and the Warrant Agent that the beneficial holder at the time of exercise of such Uncertificated Warrants (a) is not in the United States; (b) is not a U.S. Person and is not exercising such Uncertificated Warrants on behalf of a U.S. Person or a person in the United States; and (c) did not execute or deliver the Exercise Notice of the owner's intention to exercise such Uncertificated Warrants in the United States. If the Book-Entry Only Participant is not able to make or deliver the foregoing representation by initiating the electronic exercise of the Uncertificated Warrants, then such Warrants shall be withdrawn from the Book-Entry Only System, by the Book-Entry Only Participant and an individually registered Warrant Certificate shall be issued by the Warrant Agent to such beneficial owner or Book-Entry Only Participant, which certificate shall be impressed with the appropriate legends, and the exercise procedures set forth in Section 3.7 shall be followed.

(6) By causing a Participant to deliver notice to CDS, a Beneficial Owner shall be deemed to have irrevocably surrendered his Warrants so exercised and appointed such Participant to act as his or her exclusive settlement agent with respect to the exercise and the receipt of Warrant Shares in connection with the obligations arising from such exercise.

(7) Any notice which CDS determines to be incomplete, not in proper form or not duly executed shall for all purposes be void and of no effect and the exercise to which it relates shall be considered for all purposes not to have been exercised thereby. A failure by a Participant to exercise or to give effect to the settlement thereof in accordance with the Beneficial Owner's instructions will not give rise to any obligations or liability on the part of the Company or Warrant Agent to the Participant or the Beneficial Owner.

3.2 No Fractional Shares

Under no circumstances shall the Company be obliged to issue any fractional Warrant Shares or any cash or other consideration in lieu thereof upon the exercise of one or more Warrants. To the extent that the holder of one or more Warrants would otherwise have been entitled to receive on the exercise or partial exercise thereof a fraction of a Warrant Share, that holder may exercise that right in respect of the fraction only in combination with another Warrant or Warrants that in the aggregate entitle the holder to purchase a whole number of Warrant Shares.

3.3 Effect of Exercise of Warrants

(1) Upon compliance by the Warrantholder with the provisions of section 3.1, the Warrant Shares subscribed for shall be deemed to have been issued and the person to whom such Warrant Shares are to be issued shall be deemed to have become the holder of record of such Warrant Shares on the Exercise Date unless the transfer registers of the Company for the Common Shares shall be closed on such date, in which case the Warrant Shares subscribed for shall be deemed to have been issued and such person shall be deemed to have become the holder of record of such Warrant Shares on the date on which such transfer registers are reopened.

(2) Within three Business Days following the due exercise of a Warrant pursuant to section 3.1 and forthwith after the Time of Expiry, the Warrant Agent shall deliver to the Company a notice setting forth the particulars of all Warrants exercised, if any, and the persons in whose names the Warrant Shares are to be issued (as applicable) and the addresses of such holders of the Warrant Shares.

(3) Within three Business Days of the due exercise of a Warrant pursuant to section 3.1, the Company shall cause the Transfer Agent to issue, within such three Business Day period, to CDS through the Book-Entry Only System the Warrant Shares (which shall include Warrant Shares issued to a Purchaser that is a Qualified Institutional Buyer pursuant to Section 3.7(2)(b)) to which the exercising Warrantholder is entitled pursuant to the exercise or mail to the person in whose name the Warrant Shares so subscribed for are to be issued, as specified in the exercise form completed on the Warrant Certificate, at the address specified in such exercise form, a certificate or certificates for the Warrant Shares to which the Warrantholder is entitled and, if applicable, shall cause the Warrant Agent to mail a Warrant Certificate representing any Warrants not then exercised.

3.4 Cancellation of Warrants

All Warrants surrendered to the Warrant Agent pursuant to sections 2.6, 2.8(2), 2.10 or 3.1 shall be cancelled by the Warrant Agent and the Warrant Agent shall record the cancellation of such Warrants on the register of holders maintained by the Warrant Agent pursuant to subsection 2.8(1). The Warrant Agent shall, if required by the Company, furnish the Company with a certificate identifying the Warrants so cancelled. All Warrants that have been duly cancelled shall be without further force or effect whatsoever.

3.5 Subscription for less than Entitlement

The holder of any Warrant may subscribe for and purchase a whole number of Warrant Shares that is less than the number that the holder is entitled to purchase pursuant to a surrendered Warrant. In such event, the holder thereof shall be entitled to receive a new Warrant in respect of the balance of Warrants that were not then exercised, such new Warrant to contain the same legend as provided for in subsections 2.21(1) and (2) and 2.22(2) if applicable.

3.6 Expiration of Warrant

After the Time of Expiry, all rights under any Warrant in respect of which the right of subscription and purchase herein and therein provided for shall not theretofore have been exercised shall wholly cease and terminate and such Warrant shall be void and of no effect.

3.7 Prohibition on Exercise by U.S. Persons; Exception

(1) Warrants may not be exercised within the United States or by or on behalf of, or for the account or benefit of, any U.S. Person or any person in the United States unless an exemption is available from the registration requirements of the U.S. Securities Act and applicable state securities laws and the holder of the Warrants has furnished an opinion of counsel of recognized standing in form and substance satisfactory to the Company to such effect; provided that a Qualified Institutional Buyer that purchased the Units in the Private Placement will not be required to deliver an opinion of counsel in connection with the exercise of Warrants forming part of the Units, provided it provides the certification required in paragraph 3.7(2)(b) below. The Warrant Agent shall be entitled to rely upon the registered address of the Warrantholder as set forth in such Warrantholder's register for the purchase of Units in determining whether the address is in the United States or the Warrantholder is a U.S. Person.

(2) Any holder which exercises any Warrants shall provide to the Company either:

(d) a written opinion of counsel of recognized standing in form and substance satisfactory to the Company to the effect that an exemption from the registration requirements of the U.S. Securities Act and applicable state securities laws is available for the issuance of the Warrant Shares issuable on exercise of the Warrants.

The notice convening any such meeting may be signed by an appropriate officer of the Warrant Agent or of the Company or the person designated by such Warrantholders, as the case may be.

6.7 Poll and Voting

On every extraordinary resolution, and when demanded by the chairman or by one or more of the Warrantholders acting in person or by proxy on any other question submitted to a meeting and after a vote by show of hands, a poll shall be taken in such manner as the chairman shall direct.

(d) generally for the calling of meetings of Warrantholders and the conduct of business thereat including setting a record date for Warrantholders entitled to receive notice of or to vote at such meeting.

Any regulations so made shall be binding and effective and the votes given in accordance therewith shall be valid and shall be counted. Save as such regulations may provide, the only persons who shall be recognized at any meeting as a Warrantholder, or be entitled to vote or be present at the meeting in respect thereof (subject to section 6.9), shall be Warrantholders or persons holding proxies of Warrantholders.

6.9 Company, Warrant Agent and Counsel may be Represented

The Company and the Warrant Agent, by their respective directors, officers and employees and the counsel for each of the Company, the Warrantholders and the Warrant Agent may attend any meeting of the Warrantholders and speak thereat but shall not be entitled to vote unless in their capacities as Warrantholders or proxies therefor.

6.10 Powers Exercisable by Extraordinary Resolution

In addition to all other powers conferred upon them by any other provisions of this Indenture or by law, the Warrantholders at a meeting shall have the power, exercisable from time to time by extraordinary resolution:

(a) to agree with the Company to any modification, alteration, compromise or arrangement of the rights of Warrantholders and/or the Warrant Agent in its capacity as Warrant Agent hereunder (subject to the Warrant Agent's approval) or on behalf of the Warrantholders against the Company, whether such rights arise under this Indenture or the Warrants or otherwise;

6.11 Meaning of "Extraordinary Resolution"

(1) The expression "extraordinary resolution" when used in this Indenture means, subject as hereinafter in this section 6.11 and in section 6.14 provided, a resolution proposed at a meeting of Warrantholders duly convened for that purpose and held in accordance with the provisions of this Article 6 at which there are present in person or by proxy Warrantholders representing at least 20% of the aggregate number of all the then outstanding Warrants and passed by the affirmative votes of Warrantholders representing not less than 662/3% of the aggregate number of all the then outstanding Warrants represented at the meeting and voted on the poll upon such resolution.

(2) If, at any meeting called for the purpose of passing an extraordinary resolution, Warrantholders representing at least 20% of the aggregate number of all the then outstanding Warrants are not present in person or by proxy within one-half hour after the time appointed for the meeting, then the meeting, if convened by Warrantholders or on a Warrantholders' Request, shall be dissolved; but in any other case it shall stand adjourned to such day, being not less than 10 Business Days later, and to such place and time as may be appointed by the chairman. Not less than three Business Days prior notice shall be given of the time and place of such adjourned meeting in the manner provided in sections 9.1 and 9.2. Such notice shall state that at the adjourned meeting the Warrantholders present in person or represented by proxy shall form a quorum but it shall not be necessary to set forth the purposes for which the meeting was originally called or any other particulars. At the adjourned meeting the Warrantholders present in person or represented by proxy shall form a quorum and may transact the business for which the meeting was originally convened and a resolution proposed at such adjourned meeting and passed by the requisite vote as provided in subsection 6.11(1) shall be an extraordinary resolution within the meaning of this Indenture notwithstanding that Warrantholders representing at least 20% of all the then outstanding Warrants are not present in person or represented by proxy at such adjourned meeting.

(3) Votes on an extraordinary resolution shall always be given on a poll and no demand for a poll on an extraordinary resolution shall be necessary.

6.12 Powers Cumulative

It is hereby declared and agreed that any one or more of the powers or any combination of the powers in this Indenture stated to be exercisable by the Warrantholders by extraordinary resolution or otherwise may be exercised from time to time and the exercise of any one or more of such powers or any combination of powers from time to time shall not be deemed to exhaust the right of the Warrantholders to exercise such powers or combination of powers then or thereafter from time to time.

6.13 Minutes

(3) The Warrant Agent shall not be bound to do or take any act, action or proceeding for the enforcement of any of the obligations of the Company under this Indenture unless and until it shall have received a Warrantholders' Request specifying the act, action or proceeding that the Warrant Agent is requested to take. The obligation of the Warrant Agent to commence or continue any act, action or proceeding for the purpose of enforcing any rights of the Warrant Agent or the Warrantholders hereunder shall be conditional upon the Warrantholders furnishing, when required by notice in writing by the Warrant Agent, sufficient funds to commence or continue such act, action or proceeding and an indemnity reasonably satisfactory to the Warrant Agent and its counsel to protect and hold harmless the Warrant Agent, its officers, directors, employees, agents, successors and assigns against the costs, charges and expenses and liabilities to be incurred thereby and any loss and damage it may suffer by reason thereof.

Any such notice shall in no way limit any discretion herein given to the Warrant Agent to determine whether or not the Warrant Agent shall take action with respect to any default.

(7) In this Indenture, whenever confirmations or instructions are required to be given to the Warrant Agent, in order to be valid, such confirmations and instructions shall be in writing.

(3) Whenever Applicable Legislation requires that evidence referred to in subsection 8.3(1) be in the form of a statutory declaration, the Warrant Agent may accept the statutory declaration in lieu of a certificate of the Company required by any provision hereof. Any such statutory declaration may be made by one or more of the directors or officers of the Company and may be relied upon by the Warrant Agent in good faith without further inquiry.

(4) Proof of the execution of an instrument in writing, including a Warrantholders' Request, by any Warrantholder may be made by a certificate of a notary public or other person with similar powers that the person signing such instrument acknowledged to him the execution thereof, or by an affidavit of a witness to such execution or in any other manner which the Warrant Agent may consider adequate and in respect of a corporate Warrantholder, shall include a certificate of incumbency of such Warrantholder together with a certified resolution authorizing the person who signs such instrument to sign such instrument.

8.7 Protection of Warrant Agent

By way of supplement to the provisions of any law for the time being relating to warrant agents, it is expressly declared and agreed as follows:

(1) The Warrant Agent shall not be liable for or by reason of any representations, statements of fact or recitals in this Indenture or in the Warrants (except the representation contained in section 8.9 or in the certificate of the Warrant Agent on the Warrants) or be required to verify the same and all such statements of fact or recitals are and shall be deemed to be made by the Company (except the representation contained in section 8.9 or in the certificate of the Warrant Agent on the Warrants).

(2) Nothing herein contained shall impose any obligation on the Warrant Agent to see to or to require evidence of the registration or filing (or renewal thereof) of this Indenture or any instrument ancillary or supplemental hereto.

(3) The Warrant Agent shall not be bound to give notice to any person or persons of the execution hereof.

(4) The Warrant Agent shall not incur any liability or responsibility whatsoever or be in any way responsible for the consequence of any breach on the part of the Company of any of the covenants or warranties herein contained or of any acts of any directors, officers, employees, agents or servants of the Company.

(5) Without limiting any protection or indemnity of the Warrant Agent under any other provision hereof, or otherwise at law, the Company hereby agrees to indemnify and hold harmless the Warrant Agent and its directors, officers, agents and employees from and against any and all liabilities, losses, damages, penalties, claims, actions, suits, costs, expenses and disbursements, including reasonable legal or advisor fees and disbursements, of whatever kind and nature which may at any time be imposed on, incurred by or asserted against the Warrant Agent in connection with the performance of its duties and obligations hereunder, other than such liabilities, losses, damages, penalties, claims, actions, suits, costs, expenses and disbursements arising by reason of the gross negligence, wilful misconduct, bad faith or fraud of the Warrant Agent. This provision shall survive the resignation or removal of the Warrant Agent, or the termination of this Indenture. The Warrant Agent shall not be under any obligation to prosecute or defend any action or suit in respect of this Indenture which, in the opinion of its counsel, may involve it in expense or liability, unless the Company shall, so often as required, furnish the Warrant Agent with satisfactory indemnity and funding against such expense or liability.

(6) If any of the funds provided to the Warrant Agent hereunder are received by it in the form of an uncertified cheque or bank draft, the Warrant Agent shall delay 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.

(7) The forwarding of a cheque or the sending of funds by wire transfer by the Warrant Agent will satisfy and discharge the liability of any amounts due to the extent of the sum represented thereby unless such cheque is not honoured on presentation, provided that in the event of the non-receipt of such cheque by the payee, or the loss or destruction thereof, the Warrant Agent, upon being furnished with reasonable evidence of such non-receipt, loss or destruction and indemnity reasonably satisfactory to it, will issue to such payee a replacement cheque for the amount of such cheque.

(8) 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 judgement, 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 judgement, determine at any time that its acting under this Warrant Indenture has resulted in its being in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline, then it shall have the right to resign on 10 days' written notice to the Company 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 10-day period, then such resignation shall not be effective.

Any new Warrant Agent appointed under any provision of this section 8.8 shall be a corporation authorized to carry on the business of a transfer agent or a trust company in the Province of Ontario and, if required by 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 Company, all such conveyances or other instruments as may, in the opinion of counsel, be necessary or advisable for the purpose of assuring the same to the new Warrant Agent, provided that any resignation or removal of the Warrant Agent and appointment of a successor Warrant Agent shall not become effective until the successor Warrant Agent shall have executed an appropriate instrument accepting such appointment and, at the request of the Company, the predecessor Warrant Agent, upon payment of its outstanding remuneration and expenses, shall execute and deliver to the successor Warrant Agent an appropriate instrument transferring to such successor Warrant Agent all rights and powers of the Warrant Agent hereunder and all securities, documents of title and other instruments and all monies and properties held by the Warrant Agent hereunder.

(2) Upon the appointment of a successor Warrant Agent, the Company shall promptly notify the Warrantholders thereof in the manner provided for in section 9.1.

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.

(2) Subject to subsection 8.9(1), the Warrant Agent, in its personal or any other capacity, may buy, lend upon and deal in securities of the Company and generally may contract and enter into financial transactions with the Company or any Subsidiary without being liable to account for any profit made thereby.

Any notice so given shall be deemed to have been given on the day on which it has been published in all of the cities in which publication was required.

The Company 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.

9.7 Provisions of Indenture and Warrants for the Sole Benefit of Parties and Warrantholders

Nothing in this Indenture or the Warrant Certificates, expressed or implied, shall give or be construed to give to any person other than the parties hereto and the holders from time to time of the Warrants any legal or equitable right, remedy or claim under this Indenture, or under any covenant or provision therein contained, all such covenants and provisions being for the sole benefit of the parties hereto and the Warrantholders.

The Warrants evidenced hereby are exercisable on or before the Expiry Time, after which time the Warrants evidenced hereby shall be deemed to be void and of no further force or effect.

This Warrant Certificate represents Warrants of the Company issued or issuable under the provisions of a warrant indenture (which indenture together with all other instruments supplemental or ancillary thereto is herein referred to as the "Warrant Indenture") dated as of •, between the Company and the Warrant Agent, as may be amended from time to time, which contains particulars of the rights of the holders of the Warrants and the Company and of the Warrant Agent in respect thereof and the terms and conditions upon which the Warrants are issued and held, all to the same effect as if the provisions of the Warrant Indenture were herein set forth, to all of which the holder of this Warrant Certificate by acceptance hereof assents. Unless otherwise defined herein, all capitalized terms shall have the meanings ascribed to them in the Warrant Indenture. A copy of the Warrant Indenture will be available for inspection at the principal office of the Warrant Agent in the City of Toronto, in the Province of Ontario. In the event of any conflict between the provisions contained in this Warrant Certificate and the provisions of the Warrant Indenture, the provisions of the Warrant Indenture shall prevail.

Upon acceptance hereof, the holder hereof hereby expressly waives the right to receive any fractional Common Shares upon the exercise hereof in full or in part and further waives the right to receive any cash or other consideration in lieu thereof. The Warrants represented by this Warrant Certificate shall be deemed to have been surrendered, and payment by certified cheque, bank draft or money order shall be deemed to have been made only upon personal delivery thereof or, if sent by post or other means of transmission, upon actual receipt thereof by the Warrant Agent at its office in the City of Toronto, Ontario.

Upon due exercise of the Warrants represented by this Warrant Certificate and payment of the Warrant Exercise Price, the Company shall cause to be issued to the person(s) in whose name(s) the Common Shares so subscribed for (provided that if the Common Shares are to be issued to a person other than the registered holder of this Warrant Certificate, the holder's signature on the Exercise Form herein shall be guaranteed by a Schedule I Canadian chartered bank, or by a medallion signature guarantee from a member of a recognized Signature Medallion Guarantee Program and the holder shall pay to the Company or the Warrant Agent all applicable transfer or similar taxes and the Company shall not be required to issue or deliver certificates evidencing the Common Shares unless or until the holder shall have paid the Company or the Warrant Agent the amount of such tax (or shall have satisfied the Company that such tax has been paid or that no tax is due) the number of Common Shares to be issued to such person(s) and such person(s) shall become a holder in respect of such Common Shares with effect from the date of such exercise, and upon due surrender of this Warrant Certificate, the Warrant Agent shall issue a certificate(s) representing such Common Shares to be issued within three Business Days after the exercise of the Warrants (or portion thereof) represented hereby.

Neither the Warrants represented by this Warrant Certificate nor the Common Shares issuable upon exercise hereof have been or will be registered under the U.S. Securities Act or any state securities laws. The Warrants represented by this Warrant Certificate may not be exercised within the United States or by, or for the account or benefit of, a U.S. Person (as defined by Regulation S under the U.S. Securities Act) or a person within the United States unless registered under the U.S. Securities Act and any applicable state securities laws or unless an exemption from such registration is available.

The holder acknowledges that the Warrants represented by this Warrant Certificate and the Common Shares issuable upon exercise hereof may be offered, sold or otherwise transferred only in compliance with all applicable securities laws.

No transfer of any Warrant will be valid unless entered on the register of transfers, upon surrender to the Warrant Agent of the Warrant Certificate evidencing such Warrant, duly endorsed by, or accompanied by a transfer form or other written instrument of transfer in form satisfactory to the Warrant Agent executed by the registered holder or his executors, administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and execution satisfactory to the Warrant Agent. Subject to the provisions of the Warrant Indenture and upon compliance with the reasonable requirements of the Warrant Agent, Warrant Certificates may be exchanged for Warrant Certificates representing in the aggregate an equal number of Warrants. The Company and the Warrant Agent may treat the registered holder of this Warrant Certificate for all purposes as the absolute owner hereof. The holding of the Warrants represented by this Warrant Certificate shall not constitute the holder hereof a holder of Common Shares nor entitle him to any right or interest in respect thereof except as herein and in the Warrant Indenture expressly provided.

The Warrant Indenture provides for adjustment in the number of Common Shares to be delivered upon exercise of the right of purchase hereby granted and to the Warrant Exercise Price in certain events therein set forth.

The Warrant Indenture contains provisions making binding upon 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 the Warrantholders entitled to acquire upon the exercise of the Warrants a specified percentage of the Common Shares.

The Warrants and the Warrant Indenture shall be governed by and performed, construed and enforced in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein and shall be treated in all respects as Ontario contracts. Time shall be of the essence hereof and of the Warrant Indenture.

The Company may from time to time at any time prior to the Expiry Time purchase any of the Warrants by private agreement or otherwise.

This Warrant Certificate shall 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.

All dollar amounts herein are expressed in the lawful money of Canada.
