(b)

Such new Warrant Certificate shall bear the same legends, as set forth in Schedule “A”, which the surrendered Warrant Certificate bears

2.7

Warrants to Rank Pari Passu

All Warrants will rank pari passu, whatever may be the actual date of issue of same.

2.8

Registration and Transfer of Warrants

(a)

The Company will cause to be kept by the Warrant Agent at its office in the city of Vancouver, British Columbia:

(i)

a register of holders in which will be entered in alphabetical order the names and addresses of the holders of the Warrants and particulars of the Warrants held by them; and

(ii)

a register of transfers of Warrants in which will be entered the date and other particulars of each transfer of Warrants.

(b)

No transfer of a Warrant will be valid unless made by:

(i)

the Warrantholder or his executors, administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and execution satisfactory to the Warrant Agent with signatures guaranteed by a Canadian chartered bank or eligible guarantor institution with membership in an approved signature guarantee medallion program; or

(ii)

the liquidator of, or a trustee in bankruptcy for, a Warrantholder,

and upon compliance with such reasonable requirements as the Warrant Agent and the Company may prescribe (including, without limitation, the requirement to provide evidence of satisfactory compliance with applicable securities laws) and unless recorded on the register of transfers maintained by the Warrant Agent pursuant to subsection 2.8(a), nor until all taxes or governmental or other charges arising by reason of such transfer have been paid.

(c)

The Warrant Agent will process all proffered transfers and exercises that comply with the requirements of this Indenture in good faith upon the presumption that such transfer or exercise is permissible pursuant to all applicable legislation and the terms of this Indenture. The transferor and transferee are solely responsible for ensuring compliance with any applicable securities laws, and the Warrant Agent will have no obligations to ensure compliance with any laws applicable to the issue, transfer or exercise of the Warrants.

(d)

The transferee of a Warrant will:

(i)

after the Warrant Certificate representing the Warrants being transferred is surrendered to the Warrant Agent;

(ii)

after a duly completed and signed Transfer Form in respect of the Warrants being transferred for each transferee is lodged with the Warrant Agent; and

(iii)

upon compliance with all other conditions in that regard required by this Indenture or by law,

be entitled to have his name entered on the register of Warrantholders 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, save in respect of equities of which the Company or the transferee is required to take notice by statute or by order of a court of competent jurisdiction.

(e)

If a Warrant Certificate tendered for transfer bears the legend set forth in subsection 2.2(c), the Warrant Agent shall not register such transfer unless, in addition to the other requirements set forth herein, (A) the transfer is made to the Company or (B) a declaration to the effect set forth in Schedule “D” to this Warrant Indenture, or in such other form as the Company may from time to time prescribe, is delivered by the holder to the Warrant Agent, or (C) an opinion of counsel or other evidence has been delivered to the Warrant Agent to the effect that such transfer is exempt from the registration requirements of the 1933 Act and applicable state securities laws, and the Company has confirmed to the Warrant Agent in writing that such opinion or other evidence is satisfactory to the Company. Upon a transfer made in accordance with subparagraph (B) above, unless the Company has previously informed the Warrant Agent that the Company has ceased to be a “foreign issuer” as defined in Regulation S under the 1933 Act, the Warrant Certificate issued to the transferee shall not bear the legend set forth in subsection 2.2(c).

2.9

Registers Open for Inspection

The registers referred to in subsection 2.8(a) will be open at all reasonable times during business hours on a Business Day for inspection by the Company, the Warrant Agent or any Warrantholder. The Warrant Agent will, from time to time when requested to do so 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 Subject Securities which might then be acquired upon the exercise of the Warrants held by each such holder.

2.10

Exchange of Warrant Certificates

(a)

Warrant Certificates may, upon compliance with the reasonable requirements of the Warrant Agent, be exchanged for Warrant Certificates in any other authorized denomination representing in the aggregate the same number of Warrants. The Company will sign and the Warrant Agent will certify, in accordance with sections 2.3 and 2.4, all Warrant Certificates necessary to carry out the exchanges contemplated herein. Warrant Certificates exchanged for Warrant Certificates that bear the legend set forth in subsection 2.2(c) shall bear the same legend.

(b)

Warrant Certificates may be exchanged only at the offices of the Warrant Agent in the city of Vancouver, British Columbia or at any other place that is designated by the Company with the approval of the Warrant Agent. Any Warrant Certificates tendered for exchange will be surrendered to the Warrant Agent and cancelled.

(c)

The Warrant Agent may charge a reasonable sum for each new Warrant Certificate issued upon exchange. The party requesting the exchange, as a condition precedent thereto, will pay such charges and will pay or reimburse the Warrant Agent or the Company for all eligible transfer taxes or governmental or other similar transfer charges required to be paid in connection therewith.

2.11

Ownership of Warrants

The Company and the Warrant Agent will be entitled to treat the Warrantholder of any Warrant Certificate as the absolute owner of the Warrant represented thereby for all purposes, and neither the Company nor the Warrant Agent will be charged with notice of or be bound to see to the execution of any trust whether express, implied or constructive, in respect of any Warrants except where the Company or the Warrant Agent is required to take notice by applicable law or by order of a court of competent jurisdiction.

2.12

Adjustment of Exchange Basis

The Warrant Exercise Price and the Exchange Basis will be subject to adjustment from time to time in the events and in the manner provided as follows:

(a)

If and whenever at any time after the date hereof and prior to the Time of Expiry the Company will:

(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 pursuant to the exercise of directors’, officers’, employees’ or service providers’ stock options granted under the Company’s stock option plan);

(ii)

subdivide, redivide or change its then outstanding Common Shares into a greater number of shares; or

(iii)

reduce, combine or consolidate its then outstanding Common Shares into a lesser number of shares,

(any of such events in these clauses (i), (ii) or (iii) being called a “Common Share Reorganization”), then the Exchange Basis will be adjusted effective immediately after the effective date of, or the record date at which the holders of Common Shares are determined for the purpose of, the Common Share Reorganization by multiplying the Exchange Basis in effect immediately prior to such effective date or record date by a fraction:

(A)

the numerator of which will be the number of Common Shares outstanding immediately after giving effect to such Common Share Reorganization (including, in the case where securities exchangeable for or convertible into Common Shares are distributed, the number of Common Shares that would have been outstanding had such securities been exchanged for or converted into Common Shares on such effective date or 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 effective date or record date on the basis upon which they first become convertible or exchangeable); and

(B)

the denominator of which will be the number of Common Shares outstanding on such effective date or record date before giving effect to such Common Share Reorganization,

The resulting product, adjusted to the nearest 1/10,000th, will thereafter be the Exchange Basis until further adjusted as provided in this Article 2,

(b)

If and whenever at any time after the date hereof and prior to the Time of Expiry, the Company will issue to all or substantially all the holders of Common Shares rights, options or warrants under which such holders are entitled, during a period expiring not more than 45 days after the record date for such issue (the “Rights Period”), 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 to the holder in the case of securities exchangeable for or convertible into Common shares) of less than 95% of the Current Market Price for the Common Shares on such record date (any of such events being called a “Rights Offering”), then the Exchange Basis will be adjusted effective immediately after the record date for the Rights Offering by multiplying the Exchange Basis in effect immediately prior to such record date by a fraction:

(i)

the numerator of which will 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, warrants or options 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, warrants or options, if any), and

(ii)

the denominator of which will be the aggregate of:

(A)

the number of Common Shares outstanding as of the record date for the Rights Offering; and

(B)

a number determined by dividing

(1)

the amount equal to the aggregate consideration payable by such holders upon the exercise of all of the rights, warrants and options 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, warrants or options (assuming the exercise of all rights, warrants and options 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, warrants and options);

(2)

the Current Market Price of the Common Shares as of the record date for the Rights Offering.

The resulting product, adjusted to the nearest 1/10,000th, will thereafter be the Exchange Basis until further adjusted in accordance with this Article 2, 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 will be readjusted effective immediately after such date of expiry to the Exchange Basis which would have been in effect on such date of expiry as if the only rights, options or warrants that had been issued in the Rights Offering were those that had been 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 will be readjusted effective immediately after such date of expiry to the Exchange Basis which would have been in effect on such date of expiry as if the only exchangeable or convertible securities that had been issued in the Rights Offering were those that were exchanged for or converted into Common Shares.

(c)

If and whenever at any time after the date hereof and prior to the Time of Expiry the Company will fix a record date for the issue or distribution to all or substantially all the holders of the Common Shares of:

(i)

shares of the Company of any class other than Common Shares;

(ii)

rights, options or warrants (other than rights, options or warrants issued pursuant to a Rights Offering) to acquire Common Shares or securities exchangeable for or convertible into Common Shares;

(iii)

evidences of indebtedness; or

(iv)

any cash, property or other assets;

and if such issuance or distribution does not constitute a Common Share Reorganization or a Rights Offering (any of such non-excluded events being herein called a “Special Distribution”), the Exchange Basis will 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:

(v)

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

(vi)

the denominator of which will be:

(A)

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

(B)

the fair market value, as determined by action by the directors of the Company, acting reasonably and in good faith (whose determination will be conclusive), subject to the prior written consent of each Principal Securities Exchange (to the extent required by the rules and regulations thereof), 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 will 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 1/10,000th, will thereafter be the Exchange Basis until further adjusted as provided in this Article 2.

(d)

If and whenever at any time after the date hereof and prior to the Time of Expiry there will be a reclassification of Common Shares at any time outstanding or change 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 wholly-owned subsidiary of the Company) 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 will exercise his right to receive Common Shares pursuant to Warrant(s) will be entitled to receive, and will accept in lieu of the number of Subject Securities to which such holder was theretofore entitled upon such exercise, the aggregate number of shares, other securities or other property (including cash) which such holder would have 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 Subject Securities to which such holder was theretofore entitled upon exercise. If determined appropriate by the Warrant Agent, appropriate adjustments will 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 will 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 will 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 will for all purposes be conclusively deemed to be an appropriate adjustment.

(e)

Any adjustment of the Exchange Basis pursuant to subsections 2.12(a), (b), (c) and (d) above, including any readjustment, will include a corresponding adjustment to the Warrant Exercise Price which will be calculated by multiplying the Warrant Exercise Price by a fraction: (i) the numerator of which will be the Exchange Basis prior to the adjustment, and (ii) the denominator of which will be the Exchange Basis after the adjustment.

(f)

Forthwith upon the occurrence of any of the events referred to in the preceding subsections 2.12(a), (b), (c) and (d) above, the Company will:

(i)

file with the Warrant Agent a certificate of the Company specifying the required adjustment; and

(ii)

give notice to the Warrantholders of the required adjustment in the manner provided in section 10.2.

2.13

Rules Regarding Calculation of Adjustment of Exchange Basis

For the purposes of section 2.12:

(a)

The adjustments provided for in section 2.12 will be cumulative and such adjustments will be made successively whenever an event referred to therein will occur, subject to the following subsections of this section 2.13.

(b)

If the purchase price provided for in any Rights Offering (the “Rights Offering Price”) is decreased, the Exchange Basis will 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 2.12(b) 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 2.12.

(c)

No adjustment in the Exchange Basis will be required unless such adjustment would result in a change to the then prevailing Warrant Exercise Price of at least 1% or of at least one-one hundredth of a Common Share based on the prevailing Exchange Basis provided, however, that any adjustments which, except for the provisions of this subsection would otherwise have been required to be made, will be carried forward and taken into account in any subsequent adjustment.

(d)

No adjustment in the Exchange Basis will be made in respect of any event described in section 2.12, other than the events referred to in clauses (ii) and (iii) of subsection (a) 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, such participation being subject to the prior written consent of each Principal Securities Exchange (to the extent required by the rules and regulations thereof).

(e)

No adjustment in the Exchange Basis will be made pursuant to section 2.12 in respect of the issue from time to time of Common Shares purchasable on exercise of the Warrants.

(f)

If a dispute at any time arises with respect to adjustments provided for in section 2.12, such dispute will 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, will be binding upon the Company, the Warrant Agent and the Warrantholders, subject to the prior written consent of each Principal Securities Exchange (to the extent required by the rules and regulations thereof).

(g)

If the Company will 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 will, 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 will be required by reason of the setting of such record date.

(h)

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

(i)

As a condition precedent to the taking of any action which would require any adjustment in any of the subscription rights pursuant to any of the Warrants, including the Exchange Basis, the Company will 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 which 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.

(j)

In case the Company, after the date hereof, will take any action affecting any Common Shares, other than action described in section 2.12, which in the opinion of the directors acting reasonably and in good faith would materially affect the rights of Warrantholders, the Exchange Basis will be adjusted in such manner, if any, and at such time, as the directors, in their sole discretion acting reasonably and in good faith, may determine to be equitable in the circumstances, subject to the prior written consent of each Principal Securities Exchange (to the extent required by the rules and regulations thereof). 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 will be conclusive evidence that the directors have determined that it is equitable to make no adjustment in the circumstances.

(k)

The Warrant Agent will be entitled to rely on any adjustment calculations prepared by the Company or its auditors.

2.14

Postponement of Subscription

In any case where the application of section 2.12 results in an increase in the number of Subject Securities which are issuable upon the 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 the event, the Company may postpone the issuance to the holder of the Warrant of the Subject Securities to which he is entitled by reason of such adjustment but such Subject Securities will be so issued and delivered to that holder upon completion of that event, with the number of such Subject Securities calculated on the basis of the number of Subject Securities on the date that the Warrant was exercised adjusted for completion of that event and the Company will deliver to the person or persons in whose name or names the Subject Securities are to be issued an appropriate instrument evidencing the right of such person or persons to receive such Subject Securities and the right to receive any dividends or other distributions which, but for the provisions of this section 2.14, such person or persons would have been entitled to receive in respect of such Subject Securities from and after the date that the Warrant was exercised in respect thereof.

2.15

Notice of Adjustment

(a)

At least 7 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 2.12, the Company will:

(i)

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

(ii)

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.

(b)

In case any adjustment for which a notice in subsection (a) of this section 2.15 has been given is not then determinable, the Company will promptly after such adjustment is determinable:

(i)

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

(ii)

give notice to the Warrantholders of the adjustment.

(c)

Subject to paragraph 2.13(f), the Warrant Agent will rely upon certificates and other documents filed by the Company pursuant to this section for all purposes of the adjustment.

2.16

No Action after Notice

The Company covenants with the Warrant Agent that it will not take any other corporate action which might deprive the holder of a Warrant of the opportunity of exercising the rights of acquisition pursuant thereto during the period of 7 days after the giving of the notice set forth in clause (ii) of subsection 2.15(a).

2.17

Optional Purchases by the Company

Subject to applicable law, the Company may, at any time and from time to time, purchase on any stock exchange, in the open market, by invitation for tender, by private contract or otherwise any of the Warrants, on such terms as the Company may determine. All Warrants purchased pursuant to the provisions of this section 2.17 will be forthwith delivered to, cancelled and destroyed by the Warrant Agent and will not be reissued. If required by the Company, the Warrant Agent will furnish the Company with a certificate as to such destruction.

2.18

Protection of Warrant Agent

Subject to Article 8, the Warrant Agent will not:

(a)

at any time be under any duty or responsibility to any registered holder of Warrants to determine whether any facts exist which 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 Subject Securities which may at any time be issued or delivered upon the exercise of the Warrants;

(c)

be responsible for any failure of the Company to issue, transfer or deliver the Subject Securities or certificates evidencing the same upon surrender of the Warrants for the purpose of exercising the rights or to comply with the provisions or 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.

ARTICLE 3
EXERCISE OF WARRANTS

3.1

Method of Exercise of Warrants

(a)

Subject to subsection 3.1(d) and section 3.5, a holder of Warrants may exercise the rights thereby conferred on him to acquire all or any part of the Subject Securities to which such Warrant entitles the holder, by surrendering the Warrant Certificate representing such Warrants to the Warrant Agent at any time on or before the Time of Expiry during regular business hours at its offices in the city of Vancouver, British Columbia (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: (i) a duly completed and executed Subscription Form; and (ii) 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 Warrant Exercise Price multiplied by the number of Subject Securities subscribed for. A Warrant Certificate with the duly completed and executed Subscription Form and payment of the Warrant Exercise Price will 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.

(b)

Any subscription referred to in subsection 3.1(a) will be signed by the Warrantholder, will specify the person(s) in whose name such Subject Securities are to be issued, the address(es) of such person(s) and the number of Subject Securities to be issued to each person, if more than one person is so specified. If any of the Subject Securities subscribed for are to be issued to a person(s) other than the Warrantholder, the signatures set out in the subscription referred to in subsection 3.1(a) will be guaranteed by a Canadian chartered bank or eligible guarantor institution with membership in an approved signature guarantee medallion program and the Warrantholder will pay to the Company or the Warrant Agent all applicable transfer or similar taxes and the Company will not be required to issue or deliver certificates evidencing Subject Securities unless or until such Warrantholder will have paid to the Company or the Warrant Agent on behalf of the Company the amount of such tax or will have established to the satisfaction of the Company that such tax has been paid or that no tax is due.

(c)

If at the time of exercise of the Warrants, in accordance with the provisions of subsection 3.1(a), there are any trading restrictions on the Subject Securities pursuant to applicable securities legislation or stock exchange requirements, the Company may upon the advice of counsel, endorse any certificates representing the Subject Securities to such effect.

(d)

Warrants may not be exercised and the Subject Securities to be delivered upon such exercise may not be issued or delivered unless:

(i)

the Warrants are exercised outside the United States and not by or on behalf of any U.S. Persons, the holder makes the representations set forth in box 1 of the Subscription Form, and the Subject Securities are not requested to be delivered and are not delivered to any address in the United States;

(ii)

the Warrants are exercised by the original holder of a Warrant Certificate impressed with the legend set forth in subsection 2.2(c) and the holder makes the representations set forth in box 3 of the Subscription Form; or

(iii)

the holder delivers an opinion of counsel to the effect that the exercise of the Warrants by the holder and the issuance of Subject Securities to be delivered upon exercise thereof are not subject to the registration requirements of the 1933 Act or the securities laws of any state of the United States, and the Company has provided written confirmation to the Warrant Agent to the effect that such opinion is in form and substance satisfactory to the Company.

(e)

Certificates representing Subject Securities issued upon the exercise of Warrants pursuant to subsections 3.1(d)(ii) or (iii) shall bear the following legends:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE LISTED ON THE TORONTO STOCK EXCHANGE; HOWEVER, THE SAID SECURITIES CANNOT BE TRADED THROUGH THE FACILITIES OF SUCH EXCHANGE SINCE THEY ARE NOT FREELY TRANSFERABLE, AND CONSEQUENTLY ANY CERTIFICATE REPRESENTING SUCH SECURITIES IS NOT GOOD DELIVERY IN SETTLEMENT OF TRANSACTIONS ON THE TORONTO STOCK EXCHANGE.

3.2

Disbursement of Monies

The Warrant Agent will disburse monies to the Company according to this Indenture only to the extent that monies have been deposited with it.

3.3

Effect of Exercise of Warrants

(a)

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

(b)

Within three Business Days following the due exercise of a Warrant pursuant to section 3.1, the Warrant Agent will deliver to the Company the funds received in full for the Warrants exercised.

(c)

Within three Business Days following the due exercise of a Warrant pursuant to section 3.1, the Warrant Agent will deliver to the Company a notice setting forth the particulars of all Warrants exercised, if any, and the persons in whose names the Subject Securities are to be issued and the addresses of such holders of the Subject Securities.

(d)

Within three Business Days following the due exercise of a Warrant pursuant to section 3.1, the Warrant Agent will mail to the person in whose name the Subject Securities so subscribed for are to be issued, as specified in the Subscription Form completed in respect of the Warrants exercised, at the address specified in such Subscription Form, a certificate or certificates for the Subject Securities to which the Warrantholder is entitled and, if applicable, a Warrant Certificate representing any Warrants not then exercised.

3.4

Cancellation of Warrant Certificates

All Warrant Certificates properly surrendered to the Warrant Agent pursuant to section 2.6, 2.10, 2.17 or 3.1 will be cancelled by the Warrant Agent and the Warrant Agent will record the cancellation of such Warrant Certificates on the register of holders maintained by the Warrant Agent pursuant to section 2.8. The Warrant Agent will, if required by the Company, furnish the Company with a certificate identifying the Warrant Certificates so cancelled. All Warrants represented by Warrant Certificates which have been duly cancelled will 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 Subject Securities which is less than the number which the holder is entitled to purchase pursuant to a surrendered Warrant Certificate. In such event, the holder thereof will be entitled to receive a new Warrant Certificate in respect of the balance of Subject Securities which such holder was entitled to purchase pursuant to the surrendered Warrant Certificate and which were not then purchased. Such new Warrant Certificate shall bear the same legends, as set forth in subsection 2.2, which the surrendered Warrant Certificate bears.

3.6

Expiration of Warrants

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 has not been exercised will wholly cease and terminate and such Warrant will be void and of no effect.

3.7

No Fractional Shares

Notwithstanding anything herein contained, including any adjustment provided for in Article 2, the Company will not be required, upon the exercise of any Warrants, to issue fractional Subject Securities or to distribute certificates which evidence fractional Subject Securities. The Company will not pay any amount in cash in lieu of issuing fractional Subject Securities.

ARTICLE 4

The obligations hereunder are not personally binding upon, nor will resort hereunder be had to, the directors or Shareholders of the Company or any of the past, present or future directors or Shareholders of the Company or any of the past, present or future officers, employees or agents of the Company, but only the property of the Company will be bound in respect hereof.

ARTICLE 6
MEETINGS OF WARRANTHOLDERS

6.1

Right to Convene Meetings

The Warrant Agent may, at any time and from time to time, and will on receipt of a written request of the Company or of a Warrantholders’ Request, convene a meeting of the Warrantholders provided that the Warrant Agent has been provided with sufficient funds and is indemnified to its reasonable satisfaction by the Company or by the Warrantholders signing such Warrantholders’ Request against the costs, charges, expenses and liabilities which may be incurred in connection with the calling and holding of such meeting. If, within 15 Business Days after the receipt of a written request of the Company or a Warrantholders’ Request and indemnity given as aforesaid, the Warrant Agent fails to give the requisite notice specified in section 6.2 to convene a meeting, the Company or such Warrantholders, as the case may be, may convene such meeting. Every such meeting will be held in the city of Vancouver or at such other place in Canada as may be approved or determined by the Warrant Agent.

6.2

Notice

At least 21 days prior notice of any meeting of Warrantholders will be given to the Warrantholders in the manner provided for in section 10.2 and a copy of such notice will be delivered to the Warrant Agent, unless the meeting has been called by the Warrant Agent, and to the Company, unless the meeting has been called by the Company. Such notice will state the time and place of the meeting, the general nature of the business to be transacted and will contain such information as is reasonably necessary to enable the Warrantholders to make a reasoned decision on the matter, but it will not be necessary for any such notice to set out the terms of any resolution to be proposed or any of the provisions of this Article 6. 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 the Warrantholders, as the case may be.

6.3

Chairman

The Warrant Agent may nominate in writing an individual to be Chairman of the meeting and if no individual is so nominated, or if the individual so nominated is not present within 15 minutes after the time fixed for the holding of the meeting, the Warrantholders present in person or by proxy will appoint an individual present to be Chairman of the meeting. The Chairman of the meeting need not be a Warrantholder.

6.4

Quorum

No business will be transacted at any meeting unless a quorum is present at the commencement of business. Subject to the provisions of section 6.11, at any meeting of the Warrantholders a quorum will consist of one Warrantholder present in person or represented by proxy and representing at least 10% of the aggregate number of Subject Securities which may be acquired upon the exercise of all the then outstanding Warrants. If a quorum of the Warrantholders is not present within one-half hour from the time fixed for holding any meeting, the meeting, if requested by the Warrantholders or on a Warrantholders’ Request, will be dissolved; but in any other case the meeting will be adjourned to the same day in the next week

(unless such day is not a Business Day in which case it will be adjourned to the next following Business Day) at the same time and place to the extent possible and, subject to the provisions of section 6.11, no notice of the adjournment need be given. Any business may be brought before or dealt with at an adjourned meeting which might have been dealt with at the original meeting in accordance with the notice calling the same. Subject to the provisions of section 6.11, At the adjourned meeting the Warrantholders present in person or represented by proxy will form a quorum and may transact the business for which the meeting was originally convened, notwithstanding that they may not represent at least 10% of the aggregate number of Subject Securities which may be acquired upon the exercise of all the then outstanding Warrants then unexercised and outstanding.

6.5

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 any such meeting, and no notice of such adjournment need be given except such notice, if any, as the meeting may prescribe.

6.6

Show of Hands

Every question submitted to a meeting will be decided in the first place by a majority of the votes given on a show of hands except that votes on an Extraordinary Resolution will be given in the manner hereinafter provided. At any such meeting, unless a poll is duly demanded 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 will be conclusive evidence of the fact.

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 will be taken in such manner as the Chairman will direct. Questions other than those required to be determined by Extraordinary Resolution will be decided by a majority of the votes cast on the poll. On a show of hands, every person who is present and entitled to vote, whether as a Warrantholder or as proxy for one or more absent Warrantholders, or both, will have one vote. On a poll, each Warrantholder present in person or represented by a proxy duly appointed by instrument in writing will be entitled to one vote in respect of each whole Subject Security which he (or the Warrantholder appointing him as proxy) is entitled to acquire upon the exercise of the Warrant then held by him. A proxy need not be a Warrantholder. The Chairman of any meeting will be entitled, both on a show of hands and on a poll, to vote in respect of the Warrants, if any, held or represented by him.

6.8

Regulations

Subject to the provisions of this Indenture, the Warrant Agent or the Company with the approval of the Warrant Agent may from time to time make and from time to time vary such regulations as it will consider necessary or appropriate:

(a)

6.11

Meaning of Extraordinary Resolution

(a)

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 Warrantholders present in person or represented by proxy representing at least 25% of the aggregate number of Subject Securities which may be acquired upon the exercise of all the then outstanding Warrants and passed by the affirmative votes of Warrantholders representing not less than 66 2/3% of the aggregate number of Subject Securities which may be acquired upon the exercise of all the then outstanding Warrants represented at the meeting and voted on the poll upon such resolution.

(b)

If, at any meeting called for the purpose of passing an Extraordinary Resolution, Warrantholders representing at least 25% of the aggregate number of Subject Securities which may be acquired upon the exercise 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, will be dissolved; but in any other case it will stand

adjourned to such day, being not less than six or more than ten Business Days later, and to such place and time in Canada as may be determined by the Chairman. Not less than three Business Days prior notice will be given to Warrantholders in the manner provided for in section 10.2 and a copy of such notice will be delivered to the Warrant Agent, unless the meeting was called by the Warrant Agent, and to the Company, unless the meeting was called by the Company. Such notice will state that at the adjourned meeting the Warrantholders present in person or represented by proxy will form a quorum but it will 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 will 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(a) will be an Extraordinary Resolution within the meaning of this Indenture notwithstanding that Warrantholders representing at least 25% of the aggregate number of Subject Securities which may be acquired upon the exercise of all the then outstanding Warrants are not present in person or represented by proxy at such adjourned meeting.

(c)

Votes on an Extraordinary Resolution will always be given on a poll and no demand for a poll on an Extraordinary Resolution will 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 will 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

Minutes of all resolutions and proceedings at every meeting of Warrantholders will be made and duly entered in books to be from time to time provided for that purpose by the Warrant Agent at the reasonable expense of the Company, and any such minutes as aforesaid, if signed by the Chairman of the meeting at which such resolutions were passed or proceedings held, or by the Chairman of the next succeeding meeting of the Warrantholders, will be prima facie evidence of the matters therein stated and, until the contrary is proved, every such meeting in respect of the proceedings of which minutes will have been made will be deemed to have been duly convened and held, and all resolutions passed thereat or proceedings taken will be deemed to have been duly passed and taken.

6.14

Instruments in Writing

All actions which may be taken and all powers that may be exercised by the Warrantholders at a meeting held as provided in this Article 6 also may be taken and exercised by Warrantholders representing, in the case of such actions and powers not requiring an Extraordinary Resolution, at least 51%, and, in the case of such actions and powers requiring an Extraordinary Resolution, at least 66 2/3% of the aggregate number of Subject Securities issuable upon the exercise of all the then outstanding Warrants by an instrument in writing signed in one or more counterparts by such Warrantholders in person or by attorney duly appointed in writing, and the expression “Extraordinary Resolution” when used in this Indenture will include an instrument so signed.

6.15

Binding Effect of Resolutions

Every resolution and every Extraordinary Resolution passed in accordance with the provisions of this Article 6 at a meeting of Warrantholders will be binding upon all the Warrantholders, whether present at or absent from such meeting, and every instrument in writing signed by Warrantholders in accordance with section 6.14 will be binding upon all the Warrantholders, whether signatories thereto or not, and each and every Warrantholder and the Warrant Agent (subject to the provisions for indemnity herein contained) will be bound to give effect accordingly to every such resolution and instrument in writing. In the case of an instrument in writing, the Warrant Agent will give notice in the manner contemplated in sections 10.1 and 10.2 of the effect of the instrument in writing to all Warrantholders and the Company as soon as is reasonably practicable.

6.16

Holdings by the Company or Subsidiaries of the Company Disregarded

In determining whether Warrantholders (or their proxies) are present at a meeting of Warrantholders for the purpose of determining a quorum or have concurred in any consent, waiver, Extraordinary Resolution, Warrantholders’ Request or other action under this Indenture, Warrants owned legally or beneficially by the Company or any associate or affiliate (as those terms are defined or used in the Company Act (British Columbia) (or any successor instrument) of the Company will be disregarded.

modifying any of the provisions of this Indenture or relieving the Company from any of the obligations, conditions or restrictions herein contained, provided that no such modification or relief shall be or become operative or effective if in the opinion of the Warrant Agent, relying on the opinion of counsel, the modification or relief impairs any of the rights of the Warrantholders provided hereunder, or of the Warrant Agent, and provided that the Warrant Agent may in its sole discretion decline to enter into any supplemental indenture which in its opinion may not afford adequate protection to the Warrant Agent when the same shall become operative;

In this Article, the term “Applicable Legislation” means the provisions of any statute of Canada or a province thereof and of regulations under any such named or other statute relating to warrant indentures and/or to the rights, duties and obligations of warrant agents and of corporations under warrant indentures, to the extent that such provisions are at the time in force and applicable to this Indenture.

(b)

If and to the extent that any provision of this Indenture limits, qualifies or conflicts with a mandatory requirement of Applicable Legislation, such mandatory requirement will prevail.

(c)

The Company and the Warrant Agent agree that each will at all times in relation to this Indenture and any action to be taken hereunder observe and comply with and be entitled to the benefit of Applicable Legislation.

8.2

Rights and Duties of Warrant Agent

(a)

In the exercise of the rights and duties prescribed or conferred by the terms of this Indenture, the Warrant Agent will act honestly and in good faith and will exercise the degree of care, diligence and skill that a reasonably prudent warrant agent would exercise in comparable circumstances. No provision of this Indenture will be construed to relieve the Warrant Agent from, or require any other person to indemnify the Warrant Agent against liability for its own negligence, wilful misconduct or fraud.

(b)

Subject only to subsection 8.2(a), the Warrant Agent will 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 has received a Warrantholders’ Request specifying the act, action or proceeding which 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 will 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 and its officers, directors, employees and agents against the costs, charges, expenses and liabilities to be incurred thereby and any loss and damage it may suffer by reason thereof. None of the provisions contained in this Indenture will require the Warrant Agent to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties or in the exercise of any of its rights or powers unless indemnified and funded as aforesaid.

(c)

The Warrant Agent may, before commencing or at any time during the continuance of any such act, action or proceeding, require the Warrantholders, at whose instance it is acting, to deposit with the Warrant Agent the Warrants held by them, for which Warrants the Warrant Agent will issue receipts.

(d)

Every provision of this Indenture that by its terms relieves the Warrant Agent of liability or entitles it to rely upon any evidence submitted to it is subject to the provisions of Applicable Legislation, of this section 8.2 and of section 8.3.

(e)

The Warrant Agent will retain the right not to act and will not be held liable for refusing to act unless it has received clear and reasonable documentation which complies with the terms of this Indenture. Such documentation must not require the exercise of any discretion or independent judgment.

(f)

In the event of any disagreement arising regarding the terms of this Indenture, the Warrant Agent will be entitled, at its option, to refuse to comply with any demands whatsoever until the dispute is settled either by written agreement amongst the various parties or by a court of competent jurisdiction.

(g)

The Warrant Agent will not be bound to give any notice or do or take any act, action or proceeding by virtue of the powers conferred on it hereunder unless and until it has been required to do so under the terms hereof; nor will the Warrant Agent be required to take notice of any default hereunder, unless and until notified in writing of such default, which notice will specifically set out the default desired to be brought to the attention of the Warrant Agent and in the absence of such notice the Warrant Agent may for all purposes of this Indenture conclusively assume that no default has occurred or been made in the performance or observance of the representations, warranties and covenants, agreements or conditions herein contained. Any such notice will in no way limit any discretion herein given to the Warrant Agent to determine whether or not the Warrant Agent will take action with respect to any default.

(h)

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 will be in writing.

8.3

Evidence, Experts and Advisers

(a)

In addition to the reports, certificates, opinions and other evidence required by this Indenture, the Company will furnish to the Warrant Agent such additional evidence of compliance with any provision hereof in such form as may be prescribed by Applicable Legislation, or as the Warrant Agent may reasonably require by written notice to the Company.

(b)

In the exercise of its rights and duties hereunder, the Warrant Agent may, if it is acting in good faith, rely as to the truth of the statements, the due execution and the accuracy of the opinions expressed therein, upon statutory declarations, opinions, reports, written requests, consents, or orders of the Company, certificates of the Company or other evidence furnished to the Warrant Agent, provided that such evidence complies with Applicable Legislation and the Warrant Agent examines the same and determines that such evidence complies with the applicable requirements of this Indenture.

(c)

Whenever Applicable Legislation requires that evidence referred to in subsection 8.3(a) be in the form of a statutory declaration, the Warrant Agent may accept such 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 Chairman, the Chief Executive Officer, the President, the Chief Operating Officer, the Chief Financial Officer, any Vice-president, the Corporate Secretary of the Company or any director.

(d)

The Warrant Agent may employ or retain such counsel, accountants or other experts or advisers as it may reasonably require for the purpose of discharging its duties hereunder, may act on and rely upon the advice or opinions so obtained and may pay reasonable remuneration for all services so performed by any of them, and will not be responsible for any misconduct on the part of any such experts or advisers who have been appointed with due care by the Warrant Agent. The costs of obtaining such advice will be payable by the Company as part of the fees of the Warrant Agent.

8.4

Documents, Monies, etc. Held by Warrant Agent

Any monies, securities, documents of title or other instruments that may at any time be held by the Warrant Agent subject to this Indenture may be placed in the deposit vaults of the Warrant Agent or of any Schedule I chartered bank or deposited for safekeeping with any such bank or the Warrant Agent.

The Warrant Agent will not be liable for or by reason of any statements of fact or recitals in this Indenture or in the Warrants (except the representation contained in sections 8.9 and 8.12 or in the certificate of the Warrant Agent on the Warrants) or be required to verify the same.

(b)

Nothing herein contained will 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.

(c)

The Warrant Agent will not be bound to give notice to any person of the execution hereof.

(d)

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 (the “Indemnified Parties”) 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 Indemnified Parties 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, fraud or wilful misconduct of the Indemnified Parties.

The Indemnified Parties will 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 Indemnified Parties with satisfactory indemnity and funding (satisfactory to the Indemnified Parties and their counsel) against such expense or liability.

(h)

Should the Warrant Agent have any inquiries with respect to legending procedures on the Warrant Certificates, the Warrant Agent shall be entitled to seek written direction from the Company or its legal counsel which determination shall be conclusive.

8.8

(b)

Upon the appointment of a successor Warrant Agent, the Company will promptly notify the Warrantholders thereof in the manner provided for in section 10.2.

Further, should the Warrant Agent reasonably determine at any time that its acting under this 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.

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 May 31, 2005 between the Company and the Warrant Agent 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.
