The signature of any of these directors or officers may be mechanically reproduced in facsimile and Warrant Certificates bearing those facsimile signatures shall be binding upon the Company as if they had been manually signed by the director or officer.

No Warrant Certificate shall be issued, or if issued, shall be valid or entitle the holder to the benefit hereof until it has been certified by manual signature by or on behalf of the Trustee or by manual signature by the Co-transfer Agent, substantially in the form approved by the Company and the Trustee and the certification by the Trustee or by the Co-transfer Agent upon any Warrant Certificate shall be conclusive evidence as against the Company that the Warrant Certificate so certified has been duly issued hereunder and is a valid obligation of the Company, and that the holder is entitled to the attributes and characteristics of the Warrants provided for in this Indenture. (2) The certificate of the Trustee or of the Co-transfer Agent on any Warrant Certificate issued hereunder shall not be construed as a representation or warranty by the Trustee or by the Co-transfer Agent as to the validity of this Indenture or of the Warrant Certificates (except the due certification thereof) and the Trustee or the Co-transfer Agent shall in no respect be liable or answerable for the use made of the Warrants, Certificate or of the consideration therefor, except as otherwise specified herein. - 10 - 15 ARTICLE THREE Exchange and Ownership of Warrants 3.1 Exchange of Warrants (1) One or more Warrant Certificates may, upon compliance with the reasonable requirements of the Trustee, be exchanged for one or more Warrant Certificates of different denominations evidencing, in the aggregate, the same number of Warrants as the Warrant Certificate or Warrant Certificates being exchanged. (2) Warrants may be exchanged only at the principal transfer offices of the Trustee in either of the cities of Toronto or Vancouver or at the principal transfer office of the Co-transfer Agent designated by the Company or at any other place that is designated by the Company with the approval of the Trustee. Any Warrant Certificates tendered for exchange shall be surrendered to the Trustee or to its agent or the Co-transfer Agent and, upon issuance of new Warrant Certificates in exchange therefore, cancelled. The Company shall sign all Warrant Certificates necessary to carry out exchanges as aforesaid and those Warrant Certificates shall be certified by or on behalf of the Trustee and will bear the same legends as the Warrant Certificates being exchanged. 3.2 Charges for Exchange or Transfer For each Warrant transferred or Warrant Certificate exchanged, the Trustee, or the Co-transfer Agent except as otherwise herein provided, shall charge, if required by the Company, a reasonable sum in respect of each Warrant transferred or Warrant Certificate exchanged. The party requesting the transfer or exchange, as a condition precedent thereto, shall pay such charges and shall pay or reimburse the Trustee, the Co-transfer Agent or the Company for all exigible transfer taxes or governmental or similar transfer charges required to be paid in connection therewith. 3.3 Ownership of Warrants The Company and the Trustee and their respective agents may deem and treat the holder of any Warrant as the absolute owner of that Warrant for all purposes, and the Company and the Trustee and their respective agents shall 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. 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 from any holder for the Shares or monies obtainable pursuant thereto shall be a good discharge to the Company and the Trustee for the same and neither the Company nor the Trustee shall be bound to inquire into the title of any such registered holder. - 11 - 16 3.4 Registration and Transfer of Warrants (1) The Company hereby appoints the Trustee as Registrar of the Warrants. The Company may hereafter, with the consent of the Trustee, appoint one or more other additional Registrars of the Warrants, including the Co-transfer Agent. (2) The Company shall cause a register to be kept by the Trustee, and the Trustee agrees to maintain such a register at its principal transfer offices in the City of Vancouver, in which shall be entered alphabetically, the names and addresses of the holders of Warrants and other particulars of the Warrants held by them respectively and a register of all transfers of Warrants and the date and other particulars of each transfer. Such registration shall be noted on the Warrant Certificates by the Trustee or other Registrar duly appointed pursuant to subsection 3.4(1). The Company shall also cause transfer agencies (each a "Transfer Agency") to be maintained by the Trustee, and the Trustee shall maintain such Transfer Agencies at its principal transfer office in the cities of Toronto and Vancouver and in such other place or places and by such other agent as the Company, with the approval of the Trustee, may designate. (3) No transfer of a Warrant shall be valid unless made on any one of the registers upon surrender of the Warrant Certificate to the Trustee or other Registrar duly appointed pursuant to subsection 3.4(1) accompanied by a written instrument of transfer in form satisfactory to the Trustee or other Registrar duly appointed pursuant to subsection 3.4(1) executed by the registered holder or his executors, administrator or other legal representatives or his attorney duly appointed by an instrument in writing in form and execution satisfactory to the Trustee or other Registrar duly appointed pursuant to subsection 3.4(1) and upon compliance with such reasonable requirements as the Trustee or other Registrar duly appointed pursuant to subsection 3.4(1) may prescribe, nor shall a transfer of a Warrant be valid, except in the case where a new Warrant Certificate is issued upon a transfer, unless the transfer shall have been noted on the Warrant Certificate by the Trustee or other Registrar duly appointed pursuant to subsection 3.4(1). (4) The registers referred to in this section 3.4 shall at all reasonable times be open for inspection by the Company, by the Trustee and by any Warrantholder. (5) The registered holder of a Warrant may at any time and from time to time have the registration of the Warrant transferred from the register in which the registration thereof appears to another authorized register upon compliance with such reasonable requirements as the Trustee or other registrar duly appointed pursuant to subsection 3.4(1) may prescribe. (6) Subject to subsections 3.4(7), (8) and (9), the holder of a Warrant may at any time and from time to time have the Warrant transferred at any Transfer Agency in accordance with the - 12 - 17 conditions herein, such reasonable requirements as the registrar may prescribe and all applicable securities legislation and requirements of regulatory authorities, provided however that the transfer of Warrants shall be accompanied by a Transfer Form. (7) If a Warrant Certificate tendered for transfer bears the U.S. Legend, the Trustee or other Registrar shall authenticate, register and deliver in the name of the transferee a new Warrant Certificate, representing the number of Warrants so transferred, bearing the U.S. Legend; provided, that if the Warrants are being sold in accordance with Rule 904 of Regulation S and the transferor has delivered to the Trustee or other Registrar a declaration substantially in the form set forth in Schedule B hereto, the Trustee or other Registrar shall authenticate, register and deliver in the name of the transferee a new Warrant Certificate, representing the number of Warrants so transferred, without the U.S. Legend and, provided, further, that if the Warrants are being sold pursuant to Rule 144 under the U.S. Securities Act and the transferor has delivered to the Trustee or other Registrar an opinion of counsel, of recognized standing reasonably satisfactory to the Company, to the effect that the U.S. Legend is no longer required under applicable requirements of the U.S. Securities Act or state securities laws, then the Trustee or other Registrar shall authenticate, register and deliver in the name of the transferee a new Warrant Certificate, representing the number of Warrants so transferred, without the U.S. Legend. (8) Except as required by law, neither the Company nor the Trustee nor any Registrar duly appointed pursuant to subsection 3.4(1) shall 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 written direction of the person registered as the holder thereof, whether named as Trustee or otherwise, as though that person were the beneficial owner thereof. (9) The Trustee and every Registrar duly appointed pursuant to subsection 3.4(1) shall from time to time, when requested so to do by the Company, by the Trustee or by any Warrantholder, furnish the Company, the Trustee or, upon payment by the Warrantholder of a reasonable fee, the Warrantholder, as the case may be, with a list of names and addresses of holders of Warrants entered on the registers kept by such Trustee or Registrar and showing the number of Warrants held by each such holder.

(2) The Subscription Price for Shares subscribed for under Warrants shall be paid in cash, by certified cheque, bank draft or money order payable to or to the order of the Company or to the Trustee at par at the city where the Warrant Certificate is surrendered.

(4) Any exercise form referred to in subsection 4.1(1) shall be signed by the Warrantholder or the Warrantholder's executors or administrators or other legal representatives or an attorney of the Warrantholder duly appointed by an instrument in writing satisfactory to the Trustee or the Co-transfer Agent, as the case may be. The exercise form attached to the Warrant Certificate shall specify the number of Shares that the subscriber wishes to purchase (being not more than he is entitled to purchase under the Warrant Certificate), the person or persons in whose name or names the Shares which the subscriber desires to purchase are to be issued and his or their address or addresses and the number of Shares to be issued to each such person. If any Shares subscribed for are to be issued to a person or persons other than the Warrantholder, the Warrantholder shall pay to the Trustee or to its agent all exigible transfer taxes or governmental or other charges required to be paid in respect of the transfer of the Warrants or Shares and the Company will not be required to issue or deliver any certificate evidencing any Shares unless or until that amount has been so paid or the Warrantholder has established to the satisfaction of the Company that the taxes and charges have been paid or that no taxes or charges are owing. (5) Unless box B has been checked on the exercise form referred to in subsection 4.1(1), (i) Warrants may not be exercised - 14 - 19 within the United States or by or on behalf of any U.S. Person, (ii) no Shares shall be issued to any person who has an address in the United States on the exercise form and (iii) no Shares issued upon exercise of Warrants will be delivered to any address in the United States. (6) In the event that any Warrant Certificate or Warrant Certificates have been delivered to the Trustee pursuant to subsection 4.1(1) and box B has been checked on the accompanying exercise form, then the Trustee shall cause the certificates representing the Shares issued upon exercise of any such Warrants to be affixed with the U.S. Legend. (7) If, at the time of exercise of the Warrants, there remain restrictions on resale under applicable securities legislation in respect of the Shares issuable upon exercise of the Warrants, the Company may, on the advice of counsel, endorse the certificate representing the Shares with respect to those restrictions. 4.2 Effect of the Exercise of Warrants (1) Upon exercise of a Warrant in accordance with section 4.1 and subject to sections 4.4, 4.5 and 5.3, the Company shall cause the holder thereof to be entered forthwith on its register of shareholders as the holder of the Shares so subscribed for, and the number of Shares to be issued to such person or persons shall be issued to the person or persons in whose name or names the Shares so subscribed for are to be issued as specified in the exercise form. Such person or persons shall become the shareholder or shareholders of record of those Shares with effect from the date on which the Warrant is exercised unless the register of the Company shall be closed on that date, in which case the Shares so subscribed for shall be deemed to be issued and the person or persons shall be deemed to become the shareholder or shareholders of record of the Shares on the date on which the register is reopened and the Shares shall be issued on the later date. (2) Upon the due exercise of the Warrants as aforesaid the Company shall, without charge therefor except as provided in subsection 4.1(4), forthwith cause to be delivered to the Trustee, as agent for the person or persons in whose name or names the Shares so subscribed for are to be issued as specified in the exercise forms attached to the Warrant Certificates, certificates for the appropriate number of Shares that the Warrantholders are entitled to and have elected to acquire pursuant to the Warrants surrendered. Upon receipt by the Trustee of such certificates, the Trustee shall cause such certificates to be delivered forthwith in accordance with the written delivery instructions of the holder, or in the absence of such instructions, by registered mail without charge therefor, to the person in whose names the Shares have been issued at the addresses specified in the exercise forms. - 15 - 20 4.3 Partial Exercise of Warrants A Warrantholder may subscribe for and purchase any number of Shares up to the aggregate number of Warrants represented by the Warrant Certificates surrendered. In the event of any exercise of a number of Warrants less than the number which the holder is entitled to exercise, the holder of the Warrants upon such exercise shall, in addition, be entitled to receive, without charge therefor, a new Warrant Certificate in respect of the balance of the Warrants represented by the surrendered Warrant Certificate and which were not then exercised. The Trustee shall issue a new Warrant Certificate upon surrender of the Warrant Certificate, if satisfied that the new Warrant Certificate is properly issuable. 4.4 No Fractional Shares The Company will not, pursuant to section 5.1 or under any other circumstances, be obligated to issue any fraction of a Share on the exercise of a Warrant or Warrants. If any fractional interest in a Share would, except for the provisions of this section, be deliverable upon the exercise of any Warrant, the Company shall in lieu of delivering a fractional Share therefor, satisfy the right to receive the fractional Share by payment to the holder of the Warrant of an amount in cash (computed, in the case of a fraction of a cent, to the next lower cent) equal to the same fraction of the Current Market Price per Share on the date of exercise of the Warrant. 4.5 Expiration of Warrants (1) After the Warrant Expiry Time, all rights under this Indenture and under any Warrant that has not been exercised shall wholly cease and terminate and the Warrant Certificate therefor shall be wholly void and of no effect. (2) The Company shall give notice to the Warrantholders of the Warrant Expiry Time not more than 60 and not less than 30 days prior to the Warrant Expiry Time. 4.6 Cancellation of Warrants All Warrants exercised as provided in section 4.1, partially exercised as provided in section 4.3 or exchanged for other Warrants as provided in section 3.1 shall be cancelled and destroyed by the Trustee and, if required by the Company, the Trustee shall furnish the Company with a certificate identifying the Warrant Certificates so cancelled and the number of Shares which have been issued pursuant to each. - 16 - 21 ARTICLE FIVE Adjustment to Subscription Rights 5.1 Adjustment of the Subscription Price and Subscription Rights (1) In this section the terms "record date" and "effective date" where used herein shall mean 4:30 p.m. (Vancouver time) on the relevant date. (2) The number of Shares to be acquired by a Warrantholder on exercise of a Warrant will be adjusted from time to time in the events and in the manner provided and in accordance with the provisions of and rules set out in this Article Five. (3) If and whenever at any time from the date hereof to the Warrant Expiry Time, the Company: (a) issues to all or substantially all of the holders of Shares by way of stock dividend or otherwise Shares or Convertible Securities, other than (i) the issue from time to time of Shares or Convertible Securities by way of stock dividend to shareholders who elect to receive Shares or Convertible Securities in lieu of cash dividends in the ordinary course or pursuant to a dividend reinvestment plan or (ii) as dividends paid in the ordinary course, (b) subdivides or redivides the outstanding Shares into a greater number of shares, or (c) combines, consolidates or reduces the outstanding Shares into a lesser number of shares (any of those events being herein called a "Share Reorganization"), the Price Adjustment Factor will be adjusted, effective immediately after the record date at which the holders of Shares are determined for the purposes of the Share Reorganization or the effective date if no record date is fixed, to the number that is the product of (1) the Price Adjustment Factor in effect on that effective date or record date, and (2) the fraction: (i) the numerator of which shall be the total number of Shares outstanding on that effective date or record date before giving effect to the Share Reorganization; and (ii) the denominator of which shall be the total number of Shares that are or would be outstanding immediately after that effective date or record date after giving effect to the Share Reorganization and assuming all - 17 - 22 Convertible Securities issued as part of the Share Reorganization had then been converted into or exchanged for Shares or all rights to acquire Shares had then been exercised. For the purposes of determining the number of Shares outstanding at any particular time, there shall be included therein that number of Shares which would have resulted from the conversion or exchange at that time of all Convertible Securities of the Company (other than any Convertible Securities issued to holders of Shares by way of a stock dividend and otherwise included in computing the denominator in clause (ii) hereof). Shares (and Shares issuable upon conversion or exchange of Convertible Securities) issued or to be issued under a Share Reorganization shall be deemed to be outstanding on the record date or effective date for such Share Reorganization for the purpose of calculating the number of outstanding Shares under subsections (4) and (6). To the extent that any Convertible Securities issued to holders of Shares by way of a stock dividend are not so converted or exchanged into or for Shares prior to the expiration of the right to do so, the conversion price shall then be readjusted to the conversion price which would then be in effect based upon the number of Shares actually issued upon the conversion or exchange of the Convertible Securities. (4) If and whenever at any time from the date hereof to the Warrant Expiry Time, the Company shall issue rights, options or warrants to all or substantially all of the holders of the Shares pursuant to which those holders are entitled to subscribe for, purchase or otherwise acquire Shares or Convertible Securities, to subscribe for or purchase Shares or Convertible Securities within a period of 45 days from the record date, at a price per share or at a conversion price per share of less than 95% of the Current Market Price on the earlier of the record date and the date on which the Company announces its intention to make such issuance (any such issuance being herein called a "Rights Offering" and Shares that may be acquired and exercised the Rights Offering or upon conversion of the Convertible Securities offered by the Rights Offering, being herein called "Offered Shares"), the Price Adjustment Factor shall be adjusted effective immediately after the record date so that it shall equal the number which is the product of (1) the Price Adjustment Factor in effect immediately prior to the record date, and (2) the fraction: (i) the numerator of which shall be the total number of Shares outstanding immediately prior to the record date plus a number of Shares equal to the number arrived at by multiplying the total number of additional Shares offered for subscription or purchase or into or for which the total number of Convertible Securities so offered are convertible or exchangeable by the quotient obtained by dividing the purchase or subscription price for each Share offered for subscription or - 18 - 23 purchase or the conversion price for each Convertible Security so offered by such Current Market Price for the Shares; and (ii) the denominator of which shall be the total number of Shares outstanding immediately prior to such record date plus the total number of additional Shares offered for subscription or purchase or into or for which the total number of Convertible Securities so offered are convertible or exchangeable. The adjustment shall be made successively whenever a record date is fixed, provided that if two or more such record dates or dates of announcement, as applicable, or record dates or dates of announcement, as applicable, referred to in subsection (6) are fixed within a period of 35 trading days, the adjustment shall be made successively as if each of such record dates occurred on the earliest of such record dates. To the extent that any rights, options or warrants are not so issued or any of the rights, options or warrants so issued are not exercised prior to the expiration thereof, or any Convertible Securities are not so converted into or exchanged for Shares prior to the expiration of the right to do so, the Price Adjustment Factor will be readjusted to the Price Adjustment Factor in effect immediately prior to the record date, and the Price Adjustment Factor will be further adjusted based upon the number of additional Shares actually delivered upon the exercise of the rights, options or warrants, or issued upon the conversion or exchange of the Convertible Securities, as the case may be. (5) If and whenever at any time from the date hereof to the Warrant Expiry Time, the Company shall fix a record date for the issue of rights, options or warrants to all or substantially all the holders of the outstanding Shares entitling them, for a period expiring not more than 45 days after such record date, to subscribe for or purchase Shares or Convertible Securities at a price per share (or having a conversion price per share) not less than 95% of the Current Market Price on the earlier of the record date and the date on which the Company announces its intention to make such issuance, the Price Adjustment Factor will not be adjusted. (6) If and whenever at any time from the date hereof to the Warrant Expiry Time the Company shall fix a record date for the making of an issue or distribution to all or substantially all the holders of its outstanding Common Shares resident in Canada of (a) shares of any class, excluding Shares or Convertible Securities referred to in paragraph 3(a), whether of the Company or any other corporation, or (b) rights, options or warrants, excluding those referred to in subsections (4) or (5), or (c) evidences of its indebtedness, or (d) property, cash or other assets, excluding dividends in the ordinary course or property distributed in lieu thereof at the option of the shareholders (any of such events being herein called a "Special Distribution") then, in each such case, the Price Adjustment Factor shall be adjusted on the record date so - 19 - 24 that it shall equal the number that is the product of the Price Adjustment Factor in effect immediately prior to the record date, and the fraction: (i) the numerator of which shall be the total number of Shares outstanding immediately prior to the record date multiplied by the Current Market Price on the earlier of the day immediately prior to such record date and the date on which the Company announces its intention to make such issuance, less the aggregate fair market value (as determined by the directors with the approval of the Trustee, which determination shall be conclusive) of the shares or rights, options or warrants or evidences of indebtedness or property, cash or assets so distributed; and (ii) the denominator of which shall be the total number of Shares outstanding immediately prior to the record date multiplied by such Current Market Price. The adjustment shall be made successively whenever a record date is fixed, provided that if two or more such record dates or dates of announcement, as applicable, or record dates or dates of announcement, as applicable, referred to in subsection (4) are fixed within a period of 35 trading days, the adjustment shall be made successively as if each of such record dates occurred on the earliest of such record dates. To the extent that any distribution is not so made, the Price Adjustment Factor shall then be readjusted to the Price Adjustment Factor which would then be in effect if the record date had not been fixed or to the Price Adjustment Factor which would then be in effect based upon the shares or rights, options or warrants or evidences of indebtedness or property, cash or assets actually distributed, as the case may be. (7) On any adjustment of the Price Adjustment Factor pursuant to subsections (3), (4) or (6), including any readjustment, the number of Shares purchasable on exercise of a Warrant will be adjusted, effective at the same time as the adjustment of the Price Adjustment Factor, by multiplying the number of Shares so purchasable immediately before the adjustment by a fraction which is the reciprocal of the fraction used in the adjustment of the Price Adjustment Factor. (8) If and whenever at any time from the date hereof to the Warrant Expiry Time there is: (a) a reclassification of the Shares outstanding, a change of Shares into other shares or securities, or any other capital reorganization of the Company except as described in subsections (3), (4), (5) and (6), - 20 - 25 (b) a consolidation, merger or amalgamation of the Company with or into another body corporate resulting in a reclassification of outstanding Shares or a change of Shares into other shares or securities, or (c) a transaction whereby all or substantially all the Company's undertaking and assets become the property of another corporation, through sale, lease, exchange or otherwise, (any of those events being herein called a "Corporate Reorganization"), a holder who thereafter exercises Warrants will, subject to the prior written consent of The Toronto Stock Exchange, be entitled to receive and will accept, for the Subscription Price then in effect, in lieu of the Shares (and any other securities to which Warrantholders are then entitled on the exercise of Warrants) to which he would otherwise have been entitled on exercise immediately prior to the Corporate Reorganization, the kind and amount of shares or other securities or property (including cash) that he would have been entitled to receive as a result of the Corporate Reorganization if, on the effective date thereof, he had been the holder of the number of Shares (and any other securities to which Warrantholders are then entitled on the exercise of Warrants) to which he would have been entitled on the exercise of the Warrant or Warrants immediately prior to the Corporate Reorganization. (9) As a condition precedent to taking any action that would require an adjustment pursuant to subsection (8), the Company will take all action that, in the opinion of counsel, is necessary in order that the Company, any successor or any successor to its assets and undertaking, shall be obligated to and may validly and legally issue as fully paid and non-assessable all the Shares or other shares or securities or property to which Warrantholders will be entitled on the exercise of Warrants thereafter. (10) If necessary as a result of any Corporate Reorganization, appropriate adjustments will be made in the application of the provisions set forth in this Article Five with respect to the rights and interests of Warrantholders to the end that the provisions set forth in this Article Five will thereafter correspondingly be made applicable as nearly as may reasonably be possible to any shares or other securities or property thereafter deliverable on the exercise of a Warrant. Any such adjustment will be subject to the prior written consent of The Toronto Stock Exchange, will be made by and set forth in an amendment hereto approved by the Directors and by the Trustee and will for all purposes be conclusively deemed to be an appropriate adjustment. (11) If the purchase price provided for in any right, warrant or option issued in connection with a Rights Offering is decreased, or the conversion price for Convertible Securities issued in connection with a Share Reorganization is increased, the Price Adjustment Factor shall forthwith be changed to whatever Price Adjustment Factor would have been obtained had the adjustment made - 21 - 26 in connection with the issuance of all such rights, warrants, options or Convertible Securities been made upon the basis of the purchase price as so decreased or the conversion price as so increased, provided that the provisions of this subsection shall not apply to any increase or decrease resulting from provisions in any rights, warrants, options or securities designed to prevent dilution if the increase or decrease shall not have been proportionately greater than the change, if any, in the Price Adjustment Factor to be made at the same time pursuant to the provisions of this section 5.1. 5.2 Subscription Rights Adjustment Rules The following rules and procedures will be applicable to adjustments made pursuant to section 5.1: (a) the adjustments and readjustments provided for in section 5.1 shall be cumulative and, subject to paragraph (b), will apply (without duplication) to successive issues, subdivisions, combinations, consolidations, distributions and other events that require an adjustment; (b) no adjustment in the Price Adjustment Factor, or resulting adjustment in the number of Shares issuable on exercise of Warrants, will be made unless the adjustment would result in a change of at least 1% in the prevailing Price Adjustment Factor or the number of Shares purchasable upon the exercise of the Warrants would change by at least one one-hundredth of a share, provided that any adjustment that would have been required to be made except for the provisions of this paragraph, will be carried forward and taken into account in the next adjustment; (c) no adjustment will be made in respect of an event described in paragraph (3)(a) or subsection (4) or (6) of section 5.1 if the Warrantholders are entitled to participate in the event on the same terms, mutatis mutandis, as if they had exercised their Warrants immediately before the effective date of or record date for the event and Warrantholders shall not be entitled to so participate without the prior written consent of The Toronto Stock Exchange; (d) no adjustment in the Price Adjustments Factor shall be made pursuant to section 5.1 in respect of the issue of shares, rights, options or warrants pursuant: (i) to this Indenture, (ii) the issuance of Shares pursuant to the exercise of directors, officers and employees options or options granted for services in - 22 - 27 accordance with the requirements of The Toronto Stock Exchange, or (iii) the issuance of any special warrants to L.B. Mining Co. or any affiliate thereof in part consideration for the acquisition of the Guariche property in Venezuela, the issuance of any Shares pursuant to the exercise of such special warrants, the issuance of any common share purchase warrants pursuant to the exercise of such special warrants and the issuance of any Shares pursuant to the exercise of such common share purchase warrants (except that the number of Convertible Securities will increase if such common share purchase warrants are issued prior to the expiry of their exercise period), and any such issues shall be deemed not to be a Share Reorganization, a Rights Offering or a Special Distribution; (e) for the purposes of subsections (3), (4), (5) and (6) of section 5.1, there will be deemed not to be outstanding: (i) any Share owned by or held for the account of the Company; or (ii) any Share owned by or held for the account of any Subsidiary of the Company; (f) any dispute that arises at any time with respect to any adjustment pursuant to this Indenture will be conclusively determined (as between the Company, the Warrantholders, the Trustee and all transfer agents and shareholders of the Company) by the auditors of the Company or, if they are unable or unwilling to act, by such firm of independent chartered accountants as is selected by the directors and is acceptable to the Trustee, and any determination by them will be binding on the Company, the Warrantholders, the Trustee and all transfer agents and shareholders of the Company; and (g) in the absence of a resolution of the directors fixing the record date for an event referred to in section 5.1, the Company will be deemed to have fixed as the record date therefor the date on which the event is effected or such date as may be required by law. 5.3 Postponement of Issue of Shares, etc. In any case in which section 5.1 requires an adjustment to take effect immediately after the effective date of or record date for an event, and a Warrant is exercised after that date and before the consummation of the event (which in the case of rights, - 23 - 28 options and warrants will be the date the rights, options and warrants are issued), the Company may postpone, until such consummation, issuing to the Warrantholder such of the shares, securities or property to which he is entitled pursuant to the exercise as exceeds those to which he would have been entitled if the Warrant had been exercised immediately before that date, provided however, that the Company will deliver to the Warrantholder an appropriate instrument evidencing such holder's right to receive such additional 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 shares, securities or property declared in favour of the holders of record of Shares or of such securities or property on or after that date or such later date as such holder would, but for the provisions of this section, have become the holder of record of such additional shares or of such securities or property pursuant to section 4.2. 5.4 Notice of Certain Events (1) At least 21 days before the effective date of or record date for any event referred to in section 5.1, other than a subdivision or consolidation of the Shares, that requires or might require an adjustment in the subscription rights pursuant to a Warrant, including the Price Adjustment Factor and the number of Shares purchasable on exercise of a Warrant, the Company will: (a) file with the Trustee a certificate of the Company specifying the particulars of the event and, if determinable, the adjustment and a computation of the adjustment; and (b) give notice to the Warrantholders of the particulars of the event and, if determinable, the adjustment. The notice need only set forth particulars as have been determined at the date that notice is given. (2) If notice has been given under subsection (1) and the adjustment is not then determinable, the Company shall promptly after the adjustment is determinable: (a) file with the Trustee a certificate of the Company showing the computation of the adjustment; and (b) give notice to the Warrantholders of the adjustment. 5.5 Reclassifications, Reorganizations, etc. (1) In case of: (a) any reclassifications or change of the Shares (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or consolidation), - 24 - 29 (b) any amalgamation, consolidation or merger of the Company with, or amalgamation, consolidation or merger of the Company into, any other corporation (other than an amalgamation, consolidation or merger in which the Company is the continuing corporation and which does not result in any reclassification or change, other than as aforesaid, of the Shares), (c) any reorganization of the Company, or (d) any sale, transfer or other disposition of all or substantially all of the assets of the Company, the Company, the corporation formed by the amalgamation, the corporation into which the Company shall have been merged, the reorganized Company, or the corporation which shall have acquired such assets, as the case may be, shall execute and deliver to the Trustee a supplemental indenture providing that the holder of each Warrant then outstanding shall have the right thereafter (until the Warrant Expiry Time) to exercise Warrants only into the kind and amount of shares and other securities and property (including cash) receivable upon such reclassification, change, amalgamation, merger, reorganization, sale, transfer or other disposition by a holder of the number of Shares which were purchasable upon the exercise of the Warrants had the Warrants been exercised immediately prior to the reclassification, change, amalgamation, merger, reorganization, sale, transfer or other disposition. (2) The supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article Five. (3) The provisions of this section 5.5 shall apply to successive reclassifications, changes, amalgamation, mergers, reorganizations, sales, transfers or other dispositions. 5.6 Protection of Trustee Subject to sections 10.2 and 10.3, the Trustee 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 contemplated by section 5.1, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed in making the same. 5.7 Proceedings Prior to Any Action Requiring Adjustment As a condition precedent to the taking of any action which would require an adjustment in any of these subscription rights pursuant to any of the Warrants, including the number of Shares which are to be issued by the exercise of the Warrants, the Company shall take any corporate action which may, in the opinion of counsel, be necessary in order that the Company has unissued and preserved in its authorized capital and may validly and legally issue as fully paid and non-accessible, all the Shares which the - 25 - 30 holders of such Warrants are entitled to receive on the full exercise thereof in accordance with the provisions hereof. ARTICLE SIX Rights and Covenants 6.1 Purchase of Warrants (1) The Company, when not in default under this Indenture, may purchase in the market, by private contract, by tender or otherwise all or any portion of the Warrants in such manner, from such persons and on such terms as the Company and such persons may determine. All Warrants so purchased shall forthwith be delivered to the Trustee and cancelled by it and no Warrants shall be issued in substitution therefor. (2) If, upon an invitation for tenders, more Warrants are tendered at the same lowest price than the Company is prepared to accept at that price, the Warrants to be purchased by the Company shall be selected by the Trustee by lot, or in any other manner as the Trustee may deem equitable, from the Warrants tendered by each tendering Warrantholder who tendered at such lowest price. For this purpose the Trustee may make, and from time to time amend, regulations with respect to the manner in which Warrants may be so selected and regulations so made shall be valid and binding upon all Warrantholders notwithstanding the fact that, as a result thereof, the Warrants held by a holder or represented by a Warrant Certificate become subject to purchase in part only. 6.2 General Covenants The Company covenants with the Trustee that so long as any Warrants remain outstanding and may be exercised: (a) the Company will at all times maintain its existence, carry on and conduct its business in a prudent manner and in accordance with industry standards and good business practice, keep or cause to be kept proper books of account in accordance with applicable law and, if and whenever required in writing by the Trustee, file with the Trustee copies of all annual financial statements of the Company furnished to its shareholders during the term of this Indenture; (b) the Company shall maintain the listing of the Shares on The Toronto Stock Exchange, and will take all steps necessary to ensure that the Shares issuable upon exercise of the Warrants will be listed and posted for trading on The Toronto Stock Exchange upon their issue; (c) the Company will reserve and keep available a sufficient number of Shares for issuance upon the exercise of Warrants issued by the Company hereunder; - 26 - 31 (d) the Company will cause the Shares from time to time subscribed for and purchased pursuant to the exercise of the Warrants, issued by the Company hereunder, in the manner herein provided, to be duly issued in accordance with the Warrants and the terms hereof; (e) the Company will cause the certificates representing the Shares issuable upon exercise of the Warrants from time to time in the manner herein provided, to be duly issued and delivered in accordance with the Warrants and the terms hereof; (f) upon the exercise by the holder of any Warrant of the right of purchase provided for therein and herein and, upon payment of the Subscription Price applicable thereto for each Share in respect of which the right of purchase is so exercised, all Shares issuable upon the exercise of Warrants shall be issued by the Company as fully paid and non-assessable; (g) the Company will use its best efforts to maintain its status as a "reporting issuer" (or the equivalent thereof) not in default of the requirements of the Securities Act (British Columbia) and the Securities Act (Ontario); (h) the Company is duly authorized to create and issue the Warrants to be issued hereunder, and the Warrant Certificates when issued and certified as herein provided will be legal, valid and binding obligations of the Company; (i) if, in the opinion of counsel, any prospectus or registration statement is required to be filed with, or any permission is required to be obtained from, any governmental authority or any other step is required under any applicable securities laws before any Shares which a Warrantholder is entitled to purchase pursuant to his Warrant may properly and legally be issued upon the due exercise thereof, the Company will take such action so required; and (j) generally, the Company will well and truly perform and carry out all the acts or things to be done by it as provided in this Indenture. 6.3 Trustee's Remuneration and Expenses The Company covenants that it will pay to the Trustee from time to time such reasonable remuneration for its services hereunder as may be agreed upon between the Company and the Trustee and will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances properly incurred or made by the Trustee in the administration or execution of the trusts hereby created (including the reasonable compensation and - 27 - 32 the disbursements of counsel and all other advisors and assistants not regularly in its employ), both before any default hereunder and thereafter until all duties of the Trustee under the trusts hereof shall be finally and fully performed, except any expense, disbursement or advance as may arise from the negligence, wilful misconduct or bad faith of the Trustee or of persons for whom the Trustee is responsible. 6.4 Performance of Covenants by Trustee If the Company shall fail to perform any of its covenants and obligations contained in this Indenture, the Trustee may notify the Warrantholders of the failure on the part of the Company or may itself perform any of the said covenants capable of being performed by it, but shall be under no obligation to do so or to notify the Warrantholders. All sums expended or advanced by the Trustee in so doing shall be repayable as provided in Section 6.3. No performance, expenditure or advance by the Trustee shall be deemed to relieve the Company of any default or of its continuing obligations hereunder. 6.5 Notice to Warrantholders of Certain Events The Company covenants with the Trustee for the benefit of the Trustee and the Warrantholders that, so long as any of the Warrants are outstanding, it will not: (a) pay any dividend payable in shares of any class to the holders of its Shares or make any other distribution (other than a cash distribution made as a dividend out of retained earnings or contributed surplus legally available for the payment of dividends) to the holders of its Shares, (b) offer to the holders of its Shares rights to subscribe for or to purchase any Shares or shares of any class or any other securities, rights, warrants or options, (c) make any repayment of capital on, or distribution of evidences of indebtedness or any of its assets (excluding cash dividends) to the holders of, its Shares, (d) amalgamate, consolidate or merge with any other person or sell or lease the whole or substantially the whole of its assets or undertaking, (e) effect any subdivision, consolidation or reclassification of its Shares, or (f) liquidate, dissolve or wind-up, unless, in each such case, the Company shall have given notice, in the manner specified in section 11.2, to each Warrantholder, of the action proposed to be taken and the date on which (a) the books of the Company shall close or a record shall be taken for such - 28 - 33 dividend, repayment, distribution, subscription rights or other rights, warrants or securities, or (b) such subdivision, consolidation, reclassification, amalgamation, merger, sale or lease, dissolution, liquidation or winding-up shall take place, as the case may be, provided that the Company shall only be required to specify in the notice those particulars of the action as shall have been fixed and determined at the date on which the notice is given. The notice shall also specify the date as of which the holders of Shares of record shall participate in the dividend, repayment, distribution, subscription of rights or other rights, warrants or securities, or shall be entitled to exchange their Shares for securities or other property deliverable upon such reclassification, amalgamation, merger, sale or lease, other disposition, dissolution, liquidation or winding-up, as the case may be. The notice shall be given, with respect to the actions described in subsections (a), (b), (c), (d), (e) and (f) not less than 21 days prior to the record date or the date on which the Company's transfer books are to be closed with respect thereto. 6.6 Closure of Share Transfer Books The Company further covenants and agrees that it will not during the period of any notice given under section 6.5 close its share transfer books or take any other corporate action which might deprive the Warrantholders of the opportunity of exercising their Warrants, provided that nothing contained in this section 6.6 shall be deemed to affect the right of the Company to do or take part in any of the things referred to in section 6.5 or to pay cash dividends on the shares of any class or classes in its capital from time to time outstanding.

At the adjourned meeting the Warrantholders present in person or by proxy shall form a quorum and may transact the business for which the meeting was originally convened, notwithstanding the outstanding Warrants that such Warrantholders hold. 8.5 Power to Adjourn The chairman of any meeting at which a quorum of the Warrantholders is present may, with the consent of the meeting, adjourn the meeting and no notice of the adjournment need be given except such notice, if any, as the meeting may prescribe. 8.6 Show of Hands Every question submitted to a meeting shall be decided in the first place by a majority of the votes given on a show of hands - 31 - 36 except that votes on an Extraordinary Resolution shall be given in the manner hereinafter provided. At any meeting, unless a poll is duly demanded or required as herein provided, a declaration by the chairman that a resolution has been carried or carried unanimously or by a particular majority or lost or not carried by a particular majority shall be conclusive evidence of the fact. 8.7 Poll On every Extraordinary Resolution, and on any other question submitted to a meeting upon which a poll is directed by the chairman or requested by one or more of the Warrantholders acting in person or by proxy and holding Warrants sufficient to purchase not less than 5% of the aggregate number of Shares that could be purchased under Warrants then outstanding, a poll shall be taken in such manner as the chairman shall direct.

The giving of any notice shall in no way limit the discretion of the Trustee hereunder as to whether any action is required to be taken in respect of any default hereunder; (f) the Trustee shall not be accountable with respect to the validity or value (or the kind or amount) of any Shares or other securities or property which may at any time be issued or delivered upon the exercise of the rights attaching to any Warrant; and (g) the Trustee is not responsible for any failure of the Company to make any cash payment or to issue, transfer or deliver Shares or certificates for the same upon the surrender of any Warrant Certificates and payment of the Subscription Price applicable thereto for the purpose of the exercise of the Warrants represented by such Warrant Certificates or to comply with any of the covenants contained in Article Six. 10.8 Replacement of Trustee (1) The Trustee may resign its trust and be discharged from all further duties and liabilities hereunder, except as provided in this Article Ten, by giving to the Company and the Warrantholders not less than 90 days notice in writing or, if a new Trustee has been appointed, such shorter notice as the Company accepts as sufficient.

In the event of the Trustee resigning or being removed as aforesaid or being dissolved, becoming bankrupt, going into liquidation or otherwise becoming incapable of acting hereunder, the Company shall forthwith appoint a new Trustee unless a new Trustee has already been appointed by the Warrantholders. If for any reason the Company is unable to appoint a new Trustee, the retiring Trustee or any Warrantholder may apply to the Supreme Court of British Columbia, on such notice as the Court may direct, for the appointment of a new Trustee. Any new Trustee so appointed by the Company or by the Court shall be subject to removal as aforesaid by the Warrantholders and the Company. Any new Trustee appointed under any provision of this section 10.8 shall be a corporation authorized to carry on the business of a trust company in the Province of British Columbia and Ontario and, if required by the Applicable Legislation of any other Province, in that other - 42 - 47 Province. On any such appointment the new Trustee shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Trustee 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 such powers, rights, duties and responsibilities of the new Trustee. (2) Upon the appointment of a new Trustee, the Company shall promptly give notice thereof to the Warrantholders. (3) Any corporation into or with which the Trustee may be merged or consolidated or amalgamated, or any corporation succeeding to the trust business of the Trustee, shall be the successor to the Trustee hereunder without any further act on its part or any of the parties hereto provided that the corporation would be eligible for appointment as a new Trustee under subsection 10.8(1). (4) A Warrant Certificate certified but not delivered by a predecessor Trustee may be delivered by the new or successor Trustee in the name of the predecessor Trustee or successor Trustee. 10.9 Conflict of Interest (1) The Trustee represents to the Company that at the time of the execution and delivery hereof no material conflict of interest exists between the Trustee's role as a fiduciary hereunder and its role in any other capacity and that if a material conflict of interest arises hereafter it will, within 90 days after ascertaining that it has a material conflict of interest, either eliminate the conflict of interest or assign its trust hereunder to a successor Trustee approved by the Company and meeting the requirements set forth in subsection 10.8(1). Notwithstanding the foregoing provisions of this subsection 10.9(1), if any such material conflict of interest exists or hereafter shall exist, the validity and enforceability of this Indenture and the Warrant Certificate shall not be affected in any manner whatsoever by reason thereof. (2) Subject to subsection 10.9(1), the Trustee, in its personal or any other capacity, may buy, lend on and deal in securities of the Company, may act as registrar and transfer agent for the Shares and trustee for the Special Warrants under the Special Warrant Indenture and generally may contract and enter into financial transactions with the Company or any subsidiary of the Company without being liable to account for any profit made thereby. 10.10 Acceptance of Trust The Trustee hereby accepts the trusts in this Indenture declared and provided for and agrees to perform them on the terms - 43 - 48 and conditions herein set forth and agrees to hold all rights, interests and benefits contained herein for and on behalf of those persons who become holders of Warrants from time to time issued pursuant to this Indenture. 10.11 Trustee Not to be Appointed Receiver The Trustee and any person related to the Trustee shall not be appointed a receiver, a receiver manager or liquidator of all or any part of the assets or undertaking of the Company. 10.12 Indemnity Without limiting any protection or indemnity of the Trustee under any other provision hereof, or otherwise at law, the Company hereby agrees to indemnify and hold harmless the Trustee 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 Trustee 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 negligence, bad faith or wilful misconduct of the Trustee or of persons for whom the Trustee is responsible.
