(4) The register shall be final and conclusive evidence as to all matters relating to Uncertificated Warrants with respect to which this Indenture requires the Warrant Agent to maintain records or accounts. In case of differences between the register at any time and any other time, the register at the later time shall be controlling, absent manifest error and such Uncertificated Warrants are binding on the Company.

Nothing in this Indenture or the holding of a Warrant evidenced by a Warrant Certificate shall be construed as conferring upon a Warrantholder any right or interest whatsoever as a shareholder, including but not limited to the right to vote at, to receive notice of, or to attend meetings of shareholders or any other proceedings of the Company, nor entitle the holder to any right or interest in respect thereof except as herein and in the Warrants expressly provided.

The holder of any Warrant shall be entitled to the rights evidenced by that Warrant free from all equities or rights of set-off or counterclaim between the Company and the original or any intermediate holder thereof and all persons may act accordingly and the receipt by any holder of the Warrant Shares or monies obtainable pursuant to the exercise of the Warrant shall be a good discharge to the Company and the Warrant Agent for the same and neither the Company nor the Warrant Agent shall be bound to inquire into the title of any holder.

Subject to section 3.14, the Exchange Basis shall be subject to adjustment from time to time in the events and in the manner provided as follows:

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

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

- 14 -

The resulting product, adjusted to the nearest 1/100th, shall thereafter be the Exchange Basis until further adjusted as provided in this Article 3.

Any Common Shares owned by or held for the account of the Company or any of its Subsidiaries or a partnership in which the Company is directly or indirectly a party to will be deemed not to be outstanding for the purpose of any computation. To the extent that any adjustment in the Exchange Basis occurs pursuant to this subsection 3.13(1) as a result of the fixing by the Company of a record date for the distribution of securities exchangeable or exercisable for or convertible into Common Shares and the Common Share Reorganization does not occur or any conversion, exercise or exchange rights are not fully converted, exercised or exchanged, the Exchange Basis shall be readjusted immediately after the expiry of any relevant exchange or conversion right or the termination of the Common Share Reorganization, as the case may be, to the Exchange Basis that would then be in effect, based upon the number of Common Shares actually issued and remaining issuable after such expiry and shall be further readjusted in such manner upon the expiry of any further such right.

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

- 15 -

by

The resulting product, adjusted to the nearest 1/100th, shall thereafter be the Exchange Basis until further adjusted as provided in this Article 3. Any Common Shares owned by or held for the account of the Company or any of its Subsidiaries or a partnership in which the Company is directly or indirectly a party to will be deemed not to be outstanding for the purpose of any computation. If, at the date of expiry of the rights, options or warrants subject to the Rights Offering, less than all the rights, options or warrants have been exercised, then the Exchange Basis shall be readjusted effective immediately after the date of expiry to the Exchange Basis which would have been in effect on the date of expiry if only the rights, options or warrants issued had been those exercised. If at the date of expiry of the rights of exchange, exercise or conversion of any securities issued pursuant to the Rights Offering less than all of such securities have been exchanged or exercised for, or converted into, Common Shares, then the Exchange Basis shall be readjusted effective immediately after the date of such expiry to the Exchange Basis which would have been in effect on the date of expiry if only the exchangeable, exercisable or convertible securities issued had been those securities actually exchanged or exercised for or converted into Common Shares.

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

- 16 -

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 shall be adjusted effective immediately after the record date for the Special Distribution by multiplying the Exchange Basis in effect on such record date by a fraction:

less

provided that no such adjustment shall be made if the result of such adjustment would be to decrease the Exchange Basis in effect immediately before such record date. The resulting product, adjusted to the nearest 1/100th, shall thereafter be the Exchange Basis until further adjusted as provided in this Article 3. Any shares owned by or held for the account of the Company or its Subsidiaries or a partnership of which the Company is directly or indirectly a party to shall be deemed not to be outstanding for the purpose of any such computation.

(4) If and whenever, at any time after the date hereof and prior to the Time of Expiry, there shall be a reclassification of the Common Shares at any time outstanding or change or other event pursuant to which the Common Shares are changed or exchanged into or for other shares or into or for other securities and/or property (including cash) (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 or exchange of the Common Shares into or for other shares or into or for other securities and/or property (including cash)), or a transfer (other than to a Subsidiary) of the undertaking or assets of the Company as an entirety or substantially as an entirety to another corporation or other entity (any of such events being herein called a "Capital Reorganization"), any Warrantholder who thereafter shall exercise his right to receive Warrant Shares pursuant to Warrant(s) shall be entitled to receive, and shall accept in lieu of the number of Warrant Shares to which such holder was theretofore entitled upon such exercise, the kind and amount of shares, other securities and/or other property (including cash) resulting from the Capital Reorganization which such holder would have been entitled to receive as a result of such Capital Reorganization if, on the effective date or record date thereof, as the case may be, the Warrantholder had been the registered holder of the number of Warrant Shares to which such holder was theretofore entitled upon exercise. If appropriate, adjustments shall be made as a result of any such Capital Reorganization in the application of the provisions set forth in this Article 3 with respect to the rights and interests thereafter of Warrantholders to the end that the provisions set forth in this Article 3 shall thereafter correspondingly be made applicable as nearly as may reasonably be in relation to any shares, other securities and/or other property (including cash) thereafter deliverable upon the exercise of any Warrant. Any such adjustment shall be made by and set forth in an indenture supplemental hereto approved by the directors and by the Warrant Agent and entered into pursuant to the provisions of this Indenture and shall for all purposes be conclusively deemed to be an appropriate adjustment.

- 17 -

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

For the purposes of section 3.13:

(1) The adjustments provided for in section 3.13 shall be cumulative and such adjustments shall be made successively whenever an event referred to in section 3.13 shall occur, subject to the following subsections of this section 3.14.

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

(3) No adjustment in the Exchange Basis shall be made in respect of any event described in section 3.13, other than the events referred to in paragraphs (ii) and (iii) of subsection (1) thereof, if Warrantholders are entitled to participate in such event on the same terms, mutatis mutandis, as if Warrantholders had exercised their Warrants prior to or on the effective date or record date of such event, any such participation being subject to regulatory approval.

(4) No adjustment in the Exchange Basis shall be made pursuant to section 3.13 in respect of the issue from time to time of Warrant Shares purchasable on exercise of the Warrants or pursuant to the exercise, conversion or exchange of securities of the Company outstanding as of the date hereof.

(5) The Company shall from time to time immediately after the occurrence of any event which requires an adjustment or readjustment as provided in section 3.13, deliver a certificate of the Company to the Warrant Agent specifying the nature of the event requiring the same and the amount of the adjustment or readjustment necessitated thereby and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based, which certificate shall be supported by a certificate of the Company's Auditors verifying such calculation. The Warrant Agent shall rely, and shall be protected in so doing, upon the certificate of the Company or of the Company's Auditor and any other document filed by the Company pursuant to this section 3.13 for all purposes.

- 18 -

(6) If a dispute shall at any time arise with respect to adjustments provided for in section 3.13, such dispute shall, absent manifest error, be conclusively determined by the Company's Auditors, or if they are unable or unwilling to act, by such other firm of independent chartered accountants as may be selected by the directors and any further determination, absent manifest error, shall be binding upon the Company, the Warrant Agent and the Warrantholders.

(7) If the Company shall set a record date to determine the holders of the Common Shares for the purpose of entitling them to receive any dividend or distribution or any subscription or purchase rights and shall, thereafter and before the distribution to such shareholders of any such dividend, distribution, or subscription or purchase rights, legally abandon its plan to pay or deliver such dividend, distribution, or subscription or purchase rights, then no adjustment in the Exchange Basis shall be required by reason of the setting of such record date.

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

(9) If the purchase price provided for in any Rights Offering (the "Rights Offering Price") is decreased, the Exchange Basis shall forthwith be changed so as to increase the Exchange Basis to such Exchange Basis as would have been obtained had the adjustment to the Exchange Basis made pursuant to subsection 3.13(2) upon the issuance of such Rights Offering been made upon the basis of the Rights Offering Price as so decreased, provided that the provisions of this subsection shall not apply to any decrease in the Rights Offering Price resulting from provisions in any such Rights Offering designed to prevent dilution if the event giving rise to such decrease in the Rights Offering Price itself requires an adjustment to the Exchange Basis pursuant to the provisions of section 3.13.

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

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

- 19 -

In any case where the application of section 3.13 results in an increase in the number of Common Shares that are issuable upon exercise of the Warrants taking effect immediately after the record date for a specific event, if any Warrant is exercised after that record date and prior to completion of such specific event, the Company may postpone the issuance to the Warrantholder of the Warrant Shares to which he is entitled by reason of such adjustment, but such Warrant Shares shall be so issued and delivered to that holder upon completion of that event, with the number of such Warrant Shares calculated on the basis of the number of Warrant Shares on the date that the Warrant was exercised, adjusted for completion of that event and the Company shall deliver to the person or persons in whose name or names the Warrant Shares are to be issued an appropriate instrument evidencing the right of such person or persons to receive such Warrant Shares and the right to receive any dividends or other distributions which, but for the provisions of this section 3.15, such person or persons would have been entitled to receive in respect of such Warrant Shares from and after the date that the Warrant was exercised in respect thereof.

(1) At least 14 days prior to the effective date or record date, as the case may be, of any event which requires or might require adjustment pursuant to section 3.13, the Company shall:

(2) In case any adjustment for which a notice in subsection 3.16(1) has been given is not then determinable, the Company shall promptly after such adjustment is determinable:

(3) The Warrant Agent may, absent manifest error, act and rely upon certificates and other documents filed by the Company pursuant to this section 3.16 for all purposes of the adjustment.

The Company covenants with the Warrant Agent that it will not take any other corporate action which might deprive a Warrantholder of the opportunity of exercising the rights of acquisition pursuant thereto during the period of 10 days after the giving of the notice set forth in subsection 3.16(1) and paragraph (b) of subsection 3.16(2).

- 20 -

Subject to applicable law and prior approval of the TSX, if required, the Company may from time to time purchase on any stock exchange (if then listed), in the open market, by private agreement or otherwise any of the Warrants. Any such purchase shall be made at the lowest price or prices at which, in the opinion of the board of directors of the Company, such Warrants are then obtainable, plus reasonable costs of purchase, and may be made in such manner, from such persons, and on such other terms as the Company in its sole discretion may determine. The Warrant Certificates representing the Warrants purchased pursuant to this section 3.18 shall forthwith be delivered to and cancelled by the Warrant Agent.

The Warrant Agent shall not:

ARTICLE 4

EXERCISE OF WARRANTS

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

- 21 -

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

(3) If, at the time of exercise of the Warrants, in accordance with the provisions of subsections 4.1(1) or 4.1(4), there are any trading restrictions on the Warrant Shares pursuant to Securities Laws or stock exchange requirements, the Company shall, on the advice of counsel, endorse any certificates or book-entry positions representing the Warrant Shares to such effect. The Warrant Agent is entitled to assume compliance with all Securities Laws unless otherwise notified in writing by the Company.

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

- 22 -

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

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

If the Exercise Form set forth in the Warrant Certificate shall have been amended, the Company shall cause the amended Exercise Form to be forwarded to all registered Warrantholders.

Exercise Forms and Confirmations must be delivered to the Warrant Agent at any time during the Warrant Agent's actual business hours on any Business Day prior to the Expiry Time. Any Exercise Form or Confirmations received by the Warrant Agent after business hours on any Business Day other than the Expiry Date will be deemed to have been received by the Warrant Agent on the next following Business Day.

Any Warrant with respect to which a Confirmation or Exercise Form is not received by the Warrant Agent before the Expiry Time shall be deemed to have expired and become void and all rights with respect to such Warrants shall terminate and be cancelled.

If, at any time following the initial effectiveness of a Registration Statement and prior to the Time of Expiry, the Company determines that no Registration Statement filed with the SEC is effective, or the use of any such Registration Statement is suspended, no Warrantholder will be permitted to exercise Warrants unless an exemption from the registration requirements of the U.S. Securities Act and applicable state securities laws is available, and the Company shall promptly provide written notice of such determination to the Warrant Agent. Upon receipt of such notice, the Warrant Agent shall provide a copy thereof to each registered holder of Warrants, and confirm in writing that the then outstanding Warrants may, until the earlier of (x) a Registration Statement becoming effective or ceasing to be suspended and any prospectus supplement necessary in relation thereto having been filed, or (y) the Time of Expiry, if the Current Market Price exceeds the Exercise Price, also be exercised by means of a "cashless exercise" in which the Warrantholder shall be entitled to surrender a Warrant to the Company in exchange for the issuance (following the due exercise of Warrants pursuant to section 4.1) of the number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

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

- 23 -

(ii) B = the Exercise Price per Warrant Share of such Warrant, as adjusted; and

(iii) X = the number of Warrant Shares that would otherwise be issuable upon exercise of such Warrant in accordance with its terms by means of a cash exercise rather than a cashless exercise.

The issue price for each such Warrant Share to be issued pursuant to the cashless exercise of a Warrant will be equal to (B), as defined above, and the total issue price for the aggregate number of Warrant Shares issued pursuant to the cashless exercise of a Warrant will be paid and satisfied in full by the surrender to the Company of such Warrant.

In addition, if the Company determines at any time prior to the Time of Expiry that U.S. state securities laws are not preempted with respect to exercises of the Warrants, the Company may by written notice to the Warrant Agent elect to permit exercises of Warrants that are subject to the laws of one or more U.S. jurisdictions to be exercised on a "cashless exercise" basis, pursuant to the cashless exercise formula set forth above. Upon the receipt of such notice, the Warrant Agent shall provide a copy thereof to each registered holder of Warrants, and confirm the Company's determination in writing.

The Company shall deliver to the Warrant Agent, an officer's certificate setting out the particulars of the Warrants to be exercised and the name and address of the Warrantholder, the number of Warrant Shares to be issued, and setting out the basis of the calculations pursuant to this section 4.2.

Under no circumstances shall the Company be obliged to issue any fractional Warrant Shares or any cash or other consideration in lieu thereof upon the exercise of one or more Warrants. To the extent that the holder of one or more Warrants would otherwise have been entitled to receive on the exercise or partial exercise thereof a fraction of a Warrant Share, that holder may exercise that right in respect of the fraction only in combination with another Warrant or Warrants that in the aggregate entitle the holder to purchase a whole number of Warrant Shares; otherwise fractional Warrant Shares shall be rounded down to the nearest whole number of Warrant Shares without compensation therefor.

(1) Upon compliance by the Warrantholder with the provisions of section 4.1 or section 4.2, the Warrant Shares subscribed for shall be deemed to have been issued and the person to whom such Warrant Shares are to be issued shall be deemed to have become the holder of record of such Warrant Shares on the Exercise Date unless the transfer registers of the Company for the Common Shares shall be closed on such date, in which case the Warrant Shares subscribed for shall be deemed to have been issued and such person shall be deemed to have become the holder of record of such Warrant Shares on the date on which such transfer registers are reopened.

(2) Within three Business Days following the due exercise of a Warrant pursuant to section 4.1 and forthwith after the Time of Expiry, the Warrant Agent shall deliver to the Company a notice setting forth the particulars of all Warrants exercised, if any, and the persons in whose names the Warrant Shares are to be issued (as applicable) and the addresses of such holders of the Warrant Shares.

- 24 -

(3) Within five Business Days of the due exercise of a Warrant pursuant to section 4.1, the Company shall cause the Transfer Agent to issue, within such five Business Day period, to CDS through the Book-Based System the Warrant Shares to which the exercising Warrantholder is entitled pursuant to the exercise or mail to the person in whose name the Warrant Shares so subscribed for are to be issued, as specified in the Exercise Form completed on the Warrant Certificate, at the address specified in the Exercise Form, a certificate or certificates for the Warrant Shares to which the Warrantholder is entitled and, if applicable, shall cause the Warrant Agent to mail a Warrant Certificate representing any Warrants not then exercised.

All Warrants surrendered to the Warrant Agent pursuant to sections 3.6, 3.8(2), 3.10, 3.18 or 4.1 shall be cancelled by the Warrant Agent and the Warrant Agent shall record the cancellation of such Warrants on the register of holders maintained by the Warrant Agent pursuant to subsection 3.8(1). The Warrant Agent shall, if required by the Company, furnish the Company with a certificate identifying the Warrants so cancelled. All Warrants that have been duly cancelled shall be without further force or effect whatsoever.

The holder of any Warrant may subscribe for and purchase a whole number of Warrant Shares that is less than the number that the holder is entitled to purchase pursuant to a surrendered Warrant. In such event, the holder thereof shall be entitled to receive a new Warrant Certificate, if applicable, in respect of the balance of Warrants that were not then exercised.

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

(1) In connection with any exercise of Warrants, if it is required by law, the Company shall cause to be delivered to any person in whose name the Warrant Shares issuable upon exercise of the Warrants are to be issued a prospectus that complies with the U.S. Securities Act and that is a part of a Registration Statement. Prior to the date of this Indenture, the Company has filed with securities regulatory authorities in each of the provinces and territories of Canada, other than Québec, and the SEC a prospectus supplement to the prospectus included in its Registration Statement on Form F-10 (File no. 333-249680) covering the issuance of the Warrant Shares upon exercise of the Warrants for purposes of applicable U.S. securities laws (such additional prospectus supplement was not filed in respect of, and does not qualify, any distribution of the Warrant Shares upon exercise of the Warrants in any province or territory of Canada under applicable Canadian securities laws). The Company will use commercially reasonable best efforts to maintain a Registration Statement effective until the earlier of the Time of Expiry or such time as no Warrants remain outstanding (provided, however, that nothing shall prevent the Company's amalgamation, arrangement, merger or sale, including any take-over bid, and any associated delisting or deregistration or ceasing to be a reporting issuer, provided that, so long as the Warrants are still outstanding and represent a right to acquire securities of the acquiring company, the acquiring company shall assume the Company's obligations under this Indenture). All expenses incidental to the Company's performance of or compliance with the foregoing provisions will be borne by the Company, including, without limitation: (i) all registration and filing fees and expenses; (ii) all fees and expenses of compliance with federal securities and state Blue Sky securities laws; (iii) all fees and disbursements of counsel for the Company, independent certified public accountants of the Company and technical experts retained by the Company whose consent is required to be provided with respect to any Registration Statement.

- 25 -

(2) Notwithstanding any provision of this Indenture to the contrary, unless a Registration Statement shall be effective under the U.S. Securities Act, any prospectus supplement necessary thereto shall have been filed with the SEC and state securities laws are preempted, the Warrants may only be exercised by persons who establish to the reasonable satisfaction of the Company and the Warrant Agent (which may include providing an opinion of counsel of recognized standing satisfactory to the Company and the Warrant Agent) that the issuance of the Warrant Shares pursuant to the exercise of the Warrants can be completed pursuant to and in accordance with an exemption or exclusion from the registration requirements of the U.S. Securities Act and all applicable state securities laws.

(3) If any person shall fail to establish to the satisfaction of the Company or Warrant Agent the conditions described in section 4.8(2), the holder of the applicable Warrant shall be notified by the Warrant Agent within two Business Days that the evidence provided has been deemed insufficient to permit the exercise of such Warrant and providing a description of the nature of such deficiency. In the case where the Company is not satisfied with the provided evidence, it shall furnish to the Warrant Agent either (i) the form of proper notice to be delivered to establish the required evidence or (ii) a description of the deficiency. Until such time as the Company or Warrant Agent, as the case may be, acting reasonably, is satisfied with the evidence provided, the holder of the Warrant shall not be permitted to exercise the Warrant.

(4) The Company will notify the Warrant Agent when a Registration Statement becomes effective under the U.S. Securities Act and, except in the case of a Registration Statement becoming effective on or prior to the date of this Warrant Indenture, the Warrant Agent will notify the registered holder of Warrants as required. Thereafter, the Warrant Agent may assume that a Registration Statement remains effective until otherwise notified in writing by the Company that such Registration Statement is no longer effective. The Company shall at all times be obligated to provide prompt notice to the Warrant Agent regarding any change in the effectiveness of a Registration Statement.

(1) The Warrant Agent shall be entitled to assume that Warrant Shares will be issued pursuant to the exercise of any Warrant without violating the securities laws of any applicable jurisdiction and without legending any certificate representing the Warrant Shares unless the Warrant Agent has received notice in writing from the Company stating otherwise and setting forth the restrictions on the exercise of the Warrants and any legend the certificates representing the Warrant Shares should bear.

- 26 -

(2) Neither the Company nor the Warrant Agent shall effect any exercise of a Warrant, and a Warrantholder shall not have the right to exercise any portion of a Warrant, pursuant to Article 4 or otherwise, to the extent that, after giving effect to such issuance after exercise as set forth on the Exercise Form, the Warrantholder (together with the Warrantholder's affiliates, and any other Persons acting as a group together with the Warrantholder or any of the Warrantholder's affiliates (such persons, "Attribution Parties")), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of Common Shares beneficially owned by the Warrantholder and its affiliates and Attribution Parties shall include the number of Common Shares issuable upon exercise of a Warrant with respect to which such determination is being made, but shall exclude the number of Common Shares that would be issuable upon (i) exercise of the remaining, non-exercised portion of a Warrant beneficially owned by the Warrantholder or any of its affiliates or Attribution Parties, and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company (including, without limitation, any other Equity Share equivalents), subject to a limitation on conversion or exercise analogous to the limitation contained herein, beneficially owned by the Warrantholder or any of its affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 4.9(2), beneficial ownership shall be calculated in accordance with Section 13(d) of the U.S. Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Warrantholder that neither the Warrant Agent nor the Company is representing to the Warrantholder that such calculation is in compliance with Section 13(d) of the U.S. Exchange Act and the Warrantholder further acknowledges that it is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 4.9(2) applies, the determination of whether a Warrant is exercisable (in relation to other securities owned by the Warrantholder together with any affiliates and Attribution Parties) and of which portion of a Warrant is exercisable shall be in the sole discretion and at the sole responsibility of the Warrantholder, and the submission of an Exercise Form shall be deemed to be the Warrantholder's determination of whether a Warrant is exercisable (in relation to other securities owned by the Warrantholder together with any affiliates and Attribution Parties) and of which portion of a Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and neither the Warrant Agent nor the Company shall have any obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the U. S. Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 4.9(2) in determining the number of outstanding Common Shares, a Warrantholder may rely on the number of outstanding Common Shares as reflected in (A) the Company's most recent periodic or annual report filed with the SEC or on SEDAR, as the case may be, (B) a more recent public announcement by the Company, or (C) a more recent written notice by the Company or the Company's transfer agent setting forth the number of Common Shares outstanding. Upon the written or oral request of a Warrantholder, the Company shall, within two trading days, confirm orally and in writing to the Warrantholder the number of Common Shares then outstanding. In any case, the number of outstanding Common Shares shall be determined after giving effect to the conversion or exercise of securities of the Company, including the Warrant being exercised, by the Warrantholder or its affiliates or Attribution Parties since the date as of which such number of outstanding Common Shares was reported. The "Beneficial Ownership Limitation" shall be 4.99% of the number of Common Shares outstanding immediately after giving effect to the issuance of Warrant Shares issuable upon exercise of the Warrant in question. The Warrantholder, upon written notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 4.9(2), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of Common Shares outstanding immediately after giving effect to the issuance of Warrant Shares upon exercise of the Warrant in question held by the Warrantholder and the provisions of this Section 4.9(2) shall continue to apply. Any increase in the Beneficial Ownership Limitation will not be effective until the sixty-first (61st) day after such notice is delivered to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 4.9(2) to correct this paragraph (or any portion hereof) that may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this Section 4.9(2) shall apply to a successor holder of a Warrant. For greater certainty, the Warrant Agent will have no responsibility for monitoring the beneficial ownership level of the Common Shares held by Warrantholders or their Attribution Parties and will have no liability in regards to the determinations made of whether or not a Warrantholder or their Attribution Parties would become a beneficial holder in excess of the Beneficial Ownership Limitation of the issued and outstanding Common Shares upon exercise of their Warrants.

(3) The Company acknowledges and agrees that notwithstanding any other provision of this Indenture, any default of any provision of this Article or any disruption of the market for financial services provided to cannabis businesses will result in the right of the Warrant Agent, at its sole discretion, to resign as Warrant Agent effective immediately, and the Company hereby acknowledges such right of the Warrant Agent to immediately resign. For greater certainty, no cure period or advance notice is required to be given by the Warrant Agent before the Warrant Agent may exercise such discretion.

(4) The Company acknowledges and agrees, in addition to any other provision herein relating to the resignation or replacement of the Warrant Agent, that the Warrant Agent may resign as Warrant Agent and be discharged from all further duties and liabilities hereunder, without notice, if the Warrant Agent reasonably determines that (i) the Company has become unable to continue to lawfully operate any part of its cannabis or cannabis-related business or to own or maintain, directly or indirectly, its cannabis or cannabis-related investments or operations; or (ii) the Warrant Agent would be prejudiced by continuing to act as Warrant Agent hereunder.

(5) The Company shall cause all of its subsidiaries to comply with the provisions of this Article as if such subsidiaries were expressly referred to in such provisions in replacement of references to the Company, mutatis mutandis.

If, in the opinion of counsel, any instrument is required to be filed with, or any permission, order or ruling is required to be obtained from, any securities regulatory authority or any other step is required under any federal or provincial law of Canada before the Warrant Shares may be issued or delivered to a Warrantholder, the Company covenants that it will use its commercially reasonable efforts to file such instrument, obtain such permission, order or ruling or take all such other actions, at its expense, as is required or appropriate in the circumstances.

The Company covenants that it will pay to the Warrant Agent from time to time reasonable remuneration for its services hereunder and will pay or reimburse the Warrant Agent upon its request for all reasonable expenses and disbursements of the Warrant Agent in the administration or execution of the duties and obligations hereby created (including the reasonable compensation and the disbursements of its counsel and all other advisers, experts, accountants and assistants not regularly in its employ) both before any default hereunder and thereafter until all duties of the Warrant Agent hereunder shall be finally and fully performed. Any amount owing hereunder and remaining unpaid after 30 days from the invoice date will bear interest at the then current rate charged by the Warrant Agent against unpaid invoices and shall be payable upon demand. This section shall survive the resignation or removal of the Warrant Agent and/or the termination of this Indenture.

Subject to section 9.7, if the Company shall fail to perform any of its covenants contained in this Indenture and the Company has not rectified such failure within 10 Business Days after receiving written notice from the Warrant Agent of such failure, the Warrant Agent may notify the Warrantholders of such 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 perform said covenants. All reasonable sums expended or disbursed by the Warrant Agent in so doing shall be repayable as provided in section 5.4. No such performance, expenditure or advance by the Warrant Agent shall be deemed to relieve the Company of any default hereunder or of its continuing obligations under the covenants herein contained.

ARTICLE 6

ENFORCEMENT

Subject to section 7.10, all or any of the rights conferred upon a Warrantholder by the terms of the Warrants held by him and/or this Indenture may be enforced by such Warrantholder by appropriate legal proceedings but without prejudice to the right that is hereby conferred upon the Warrant Agent to proceed in its own name to enforce each and all of the provisions herein contained for the benefit of the holders of the Warrants from time to time outstanding. The Warrant Agent shall also have the power at any time and from time to time to institute and to maintain such suits and proceedings as it may reasonably be advised shall be necessary or advisable to preserve and protect its interests and the interests of the Warrantholders.

- 32 -

The obligations hereunder (including without limitation under subsection 9.7(5)) are not personally binding upon, nor shall resort hereunder be had to, the private property of 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, and only the property of the Company (or any successor person) shall be bound in respect hereof.

ARTICLE 7

MEETINGS OF WARRANTHOLDERS

The Warrant Agent may at any time and from time to time, and shall 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 that 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 receipt of funding and indemnity given as aforesaid, the Warrant Agent fails to give the requisite notice specified in section 7.2 to convene a meeting, the Company or such Warrantholders, as the case may be, may convene such meeting. Every such meeting shall be held in the City of Vancouver, British Columbia or at such other place as may be approved or determined by the Warrant Agent.

At least 21 days' prior notice of any meeting of Warrantholders shall be given to the Warrantholders at the expense of the Company in the manner provided for in section 10.2 and a copy of such notice shall be delivered to the Warrant Agent unless the meeting has been called by it, and to the Company unless the meeting has been called by it. Such notice shall state the date, time and place of the meeting, the general nature of the business to be transacted and shall contain such information as is reasonably necessary to enable the Warrantholders to make a reasoned decision on the matter, but it shall 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 7. The notice convening any such meeting may be signed by an appropriate officer of the Warrant Agent or of the Company or the person designated by such Warrantholders, as the case may be.

The Warrant Agent may nominate in writing an individual (who need not be a Warrantholder) 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 shall appoint an individual present to be chairman of the meeting. The chairman of the meeting need not be a Warrantholder.

- 33 -

Subject to the provisions of section 7.11, at any meeting of the Warrantholders a quorum shall consist of two Warrantholders present in person or represented by proxy and representing at least 20% of the aggregate number of Warrants then outstanding. If a quorum of the Warrantholders shall not be present within one-half hour from the time fixed for holding any meeting, the meeting, if summoned by the Warrantholders or on a Warrantholders' Request, shall be dissolved; but in any other case the meeting shall be adjourned to the same day in the next week (unless such day is not a Business Day in which case it shall 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 7.11, no notice of the adjournment need be given. Any business may be brought before or dealt with at an adjourned meeting that might have been dealt with at the original meeting in accordance with the notice calling the same. At the adjourned meeting the Warrantholders present in person or represented by proxy shall form a quorum and may transact the business for which the meeting was originally convened, notwithstanding that they may not represent at least 20% of the aggregate number of Warrants then unexercised and outstanding. No business shall be transacted at any meeting, except an adjourned meeting as described above, unless a quorum is present at the commencement of business.

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.

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 except that votes on an extraordinary resolution shall 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 shall be conclusive evidence of the fact.

On every extraordinary resolution, and when demanded by the chairman or by one or more of the Warrantholders acting in person or by proxy on any other question submitted to a meeting and after a vote by show of hands, a poll shall be taken in such manner as the chairman shall direct. Questions other than those required to be determined by extraordinary resolution shall 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, shall have one vote. On a poll, each Warrantholder present in person or represented by a proxy duly appointed by instrument in writing shall be entitled to one vote in respect of each whole Warrant then held by him. A proxy need not be a Warrantholder. The chairman of any meeting shall 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.

- 34 -

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 shall consider necessary or appropriate:

Any regulations so made shall be binding and effective and the votes given in accordance therewith shall be valid and shall be counted. Save as such regulations may provide, the only persons who shall be recognized at any meeting as a Warrantholder, or be entitled to vote or be present at the meeting in respect thereof (subject to section 7.9), shall be Warrantholders or persons holding proxies of Warrantholders.

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

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

- 35 -

(1) The expression "extraordinary resolution" when used in this Indenture means, subject as hereinafter in this section 7.11 and in section 7.14 provided, a resolution proposed at a meeting of Warrantholders duly convened for that purpose and held in accordance with the provisions of this Article 7 at which there are present in person or by proxy at least two Warrantholders representing at least 20% of the aggregate number of all the then outstanding Warrants and passed by the affirmative votes of Warrantholders representing not less than 66²⁄₃% of the aggregate number of all the then outstanding Warrants represented at the meeting and voted on the poll for such resolution.

- 36 -

(2) If, at any meeting called for the purpose of passing an extraordinary resolution, Warrantholders representing at least 20% of the aggregate number of all the then outstanding Warrants are not present in person or by proxy within one-half hour after the time appointed for the meeting, then the meeting, if convened by Warrantholders or on a Warrantholders' Request, shall be dissolved; but in any other case it shall stand adjourned to such day, being not less than 10 Business Days later, and to such place and time as may be appointed by the chairman. Not less than three Business Days prior notice shall be given of the time and place of such adjourned meeting provided by press release of the Company. Such notice shall state that at the adjourned meeting the Warrantholders present in person or represented by proxy shall form a quorum but it shall not be necessary to set forth the purposes for which the meeting was originally called or any other particulars. At the adjourned meeting the Warrantholders present in person or represented by proxy shall form a quorum and may transact the business for which the meeting was originally convened and a resolution proposed at such adjourned meeting and passed by the requisite vote as provided in subsection 7.11(1) shall be an extraordinary resolution within the meaning of this Indenture notwithstanding that Warrantholders representing at least 20% of all the then outstanding Warrants are not present in person or represented by proxy at such adjourned meeting.

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

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

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

All actions that may be taken and all powers that may be exercised by the Warrantholders at a meeting held as provided in this Article 7 also may be taken and exercised by Warrantholders representing a majority, or in the case of an extraordinary resolution at least 66²⁄₃%, of the aggregate number 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 shall include an instrument so signed.

- 37 -

Every resolution and every extraordinary resolution passed in accordance with the provisions of this Article 7 at a meeting of Warrantholders shall be binding upon all Warrantholders, whether present at or absent from such meeting, and every instrument in writing signed by Warrantholders in accordance with section 7.14 shall 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) shall be bound to give effect accordingly to every such resolution and instrument in writing.

In determining whether Warrantholders 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 its Subsidiaries or in partnership of which the Company is directly or indirectly a party to shall be disregarded. The Company shall provide, upon the written request of the Warrant Agent, a certificate as to the registration particulars of any Warrants held by the Company or its Subsidiaries or in partnership of which the Company is directly or indirectly a party.

ARTICLE 8

SUPPLEMENTAL INDENTURES AND SUCCESSOR COMPANIES

From time to time the Company and the Warrant Agent may, subject to the provisions hereof and the TSX's approval, and they shall, when so required hereby, execute and deliver by their proper officers, indentures or instruments supplemental hereto, which thereafter shall form part hereof, for any one or more or all of the following purposes:

- 38 -

In the case of the amalgamation, consolidation, arrangement, merger or transfer of the undertaking or assets of the Company as an entirety or substantially as an entirety to another person (a "successor company"), the successor company resulting from the amalgamation, consolidation, arrangement, merger or transfer (if not the Company) shall be bound by the provisions hereof and all obligations for the due and punctual performance and observance of each and every covenant and obligation contained in this Indenture to be performed by the Company and the successor company shall by supplemental indenture satisfactory in form and substance to the Warrant Agent and executed and delivered by the successor company to the Warrant Agent, expressly assume those obligations.

ARTICLE 9

CONCERNING THE WARRANT AGENT

(1) 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 shall prevail.

- 39 -

(2) 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.

(1) The Warrant Agent accepts the duties and responsibilities under this Indenture, solely as custodian, bailee and agent. No trust is intended to be, or is or will be, created hereby and the Warrant Agent shall owe no duties hereunder as a trustee.

(2) In the exercise of the rights and duties prescribed or conferred by the terms of this Indenture, the Warrant Agent shall act honestly and in good faith and shall exercise the degree of care, diligence and skill that a reasonably prudent warrant agent would exercise in comparable circumstances. No provision of this Indenture shall be construed to relieve the Warrant Agent from liability for its own gross negligence, wilful misconduct, bad faith or fraud.

(3) The Warrant Agent shall not be bound to do or take any act, action or proceeding for the enforcement of any of the obligations of the Company under this Indenture unless and until it shall have received a Warrantholders' Request specifying the act, action or proceeding that the Warrant Agent is requested to take. The obligation of the Warrant Agent to commence or continue any act, action or proceeding for the purpose of enforcing any rights of the Warrant Agent or the Warrantholders hereunder shall be conditional upon the Warrantholders furnishing, when required by notice in writing by the Warrant Agent, sufficient funds to commence or continue such act, action or proceeding and an indemnity reasonably satisfactory to the Warrant Agent and its counsel to protect and hold harmless the Warrant Agent, its officers, directors, employees, agents, successors and assigns against the costs, charges and expenses and liabilities to be incurred thereby and any loss and damage it may suffer by reason thereof. None of the provisions contained in this Indenture shall 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.

(4) The Warrant Agent may, before commencing any act, action or proceeding, or at any time during the continuance thereof 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 shall issue receipts.

(5) 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.

(6) The Warrant Agent shall 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 shall have been required to do so under the terms hereof; nor shall the Warrant Agent be required to take notice of any default hereunder, unless and until notified in writing of such default, which notice shall 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 shall in no way limit any discretion herein given to the Warrant Agent to determine whether or not the Warrant Agent shall take action with respect to any default.

- 40 -

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

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

(2) In the exercise of its rights and duties hereunder, the Warrant Agent may, if it is acting in good faith, act and rely absolutely as to the truth of the statements 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 pursuant to any provision hereof or of Applicable Legislation or pursuant to a request of the Warrant Agent. The Warrant Agent shall be under no responsibility in respect of the validity of this Indenture or the execution and delivery hereof by or on behalf of the Company or in respect of the validity or the execution of any Warrant Certificate by the Company and issued hereunder, nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Indenture or in any such Warrant Certificate; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any securities to be issued upon the right to acquire provided for in this Indenture and/or in any Warrant or as to whether any securities will when issued be duly authorized or be validly issued and fully paid and non-assessable.

(3) Whenever it is provided in this Indenture or under Applicable Legislation that the Company shall deposit with the Warrant Agent resolutions, certificates, reports, opinions, requests, orders or other documents, it is intended that the truth, accuracy and good faith on the effective date thereof and the facts and opinions stated in all such documents so deposited shall, in each and every such case, be conditions precedent to the right of the Company to have the Warrant Agent take the action to be based thereon.

(4) Whenever Applicable Legislation requires that evidence referred to in subsection 9.3(1) be in the form of a statutory declaration, the Warrant Agent may accept the statutory declaration in lieu of a certificate of the Company required by any provision hereof. Any such statutory declaration may be made by one or more of the directors or officers of the Company and may be relied upon by the Warrant Agent in good faith without further inquiry.

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

- 41 -

(6) The Warrant Agent may act and rely and shall be protected in acting and relying upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, letter, or other paper document believed by it to be genuine and to have been signed, sent or presented by or on behalf of the proper party or parties. The Warrant Agent has sole discretion and shall be protected in acting and relying upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, letter or other paper document received in facsimile or e-mail form.

(7) The Warrant Agent may employ or retain such counsel, accountants, engineers, appraisers or other experts or advisers as it may reasonably require for the purpose of determining and discharging its duties hereunder and may pay reasonable remuneration for all services so performed by any of them, without taxation of costs of any counsel and shall not be responsible for any misconduct on the part of any of them who has been selected with due care by the Warrant Agent. Any reasonable remuneration paid by the Warrant Agent shall be paid by the Company in accordance with section 5.4.

(8) The Warrant Agent may act and rely and shall be protected in acting and relying in good faith on the opinion or advice of or information obtained from any counsel, accountant, appraiser, engineer or other expert or advisor, whether retained or employed by the Company or the Warrant Agent, in relation to any matter arising in fulfilling its duties and obligations hereof.

(9) The Warrant Agent may, as a condition precedent to any action to be taken by it under this Indenture, require such opinions, statutory declarations, reports, certificates or other evidence as it, acting reasonably, considers necessary or advisable in the circumstances.

(10) The Warrant Agent is not required to expend or place its own funds at risk in executing its duties and obligations.

Any securities, documents of title, monies or other instruments that may at any time be held by the Warrant Agent subject to the duties and obligations hereof, for the benefit of the Company, may be placed in the deposit vaults of the Warrant Agent or of any Schedule I Canadian chartered bank for safekeeping with any such bank (an "Approved Bank"). All interest or other income received from the Warrant Agent in respect of such deposits and investments shall, subject to section 5.4, belong to the Company and shall be paid to the Company upon discharge of this Indenture. All amounts held by the Warrant Agent pursuant to this Agreement shall be held by the Warrant Agent for the Company and the delivery of the funds to the Warrant Agent shall not give rise to a debtor-creditor or other similar relationship. The amounts held by the Warrant Agent are at the sole risk of the Company and, without limiting the generality of the foregoing, but subject to section 9.2(2), the Warrant Agent shall have no responsibility or liability for any diminution of the funds which may result from any deposit made with an Approved Bank pursuant to this section, including any losses resulting from a default by the Approved Bank or other credit losses (whether or not resulting from such a default). The parties hereto acknowledge and agree that the Warrant Agent will have acted prudently in depositing the funds at any Approved Bank, and that the Warrant Agent is not required to make further inquiries in respect of any such bank. The Warrant Agent may hold cash balances constituting part or all such monies and need not invest same. The Warrant Agent shall not be liable to account for any profit to any parties to this Indenture or to any other person or entity.

- 42 -

Subject to the provisions of this Indenture and Applicable Legislation, the Warrant Agent shall have the power to institute and to maintain such actions and proceedings as it may consider necessary or expedient to preserve, protect or enforce its interests and the interests of the Warrantholders.

The Warrant Agent shall not be required to give any bond or security in respect of the execution of the duties and obligations of this Indenture or otherwise.

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

(1) The Warrant Agent shall not be liable for or by reason of any representations, statements of fact or recitals in this Indenture or in the Warrants (except the representation contained in section 9.9 or in the certificate of the Warrant Agent on the Warrants) or be required to verify the same and all such statements of fact or recitals are and shall be deemed to be made by the Company.

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

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

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

(5) Without limiting any protection or indemnity of the Warrant Agent under any other provision hereof, or otherwise at law, the Company hereby agrees to indemnify and hold harmless the Warrant Agent, its affiliates and their directors, officers, agents, employees, successors and assigns (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, or any of them, whether at law or in equity, in any way caused by or arising, directly or indirectly, in respect of any act, deed, matter or thing whatsoever made, done acquiesced in or omitted in or about or in relation to the execution of the Indemnified Parties' duties, or any other services that Warrant Agent may provide in connection with or in any way relating to this Indenture. The Company agrees that its liability hereunder shall be absolute and unconditional regardless of the correctness of any representations of any third parties and regardless of any liability of third parties to the Indemnified Parties, and shall accrue and become enforceable without prior demand or any other precedent action or proceeding; provided that the Company shall not be required to indemnify the Indemnified Parties in the event of the gross negligence, wilful misconduct, bad faith or fraud of the Warrant Agent. This provision shall survive the resignation or removal of the Warrant Agent, or the termination of this Indenture. The Warrant Agent shall not be under any obligation to prosecute or defend any action or suit in respect of this Indenture which, in the opinion of its counsel, may involve it in expense or liability, unless the Company shall, so often as required, furnish the Warrant Agent with satisfactory indemnity and funding against such expense or liability.

- 43 -

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

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

(8) The Warrant Agent shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Warrant Agent, in its sole judgement, determines that such act might cause it to be in non-compliance with any applicable anti-money laundering, anti-terrorist or economic sanctions legislation, regulation or guideline. Further, should the Warrant Agent, in its sole judgement, determine at any time that its acting under this Warrant Indenture has resulted in its being in non-compliance with any applicable anti-money laundering, anti-terrorist or economic sanctions 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.

(9) The Warrant Agent shall not be liable for any error in judgment or for any act done or step taken or omitted by it in good faith or for any mistake, in fact or law, or for anything which it may do or refrain from doing in connection herewith except arising out of its own gross negligence, bad faith, willful misconduct or fraud.

- 44 -

(10) Notwithstanding the foregoing, or any other provision of this Indenture, any liability of the Warrant Agent shall be limited, in the aggregate, to the amount of annual retainer fees paid by the Company to the Warrant Agent under this Indenture in the 24 months immediately prior to the Warrant Agent receiving the first notice of the claim. Notwithstanding any other provision of this Indenture, and whether such losses or damages are foreseeable or unforeseeable, the Warrant Agent shall not be liable under any circumstances whatsoever for any (a) breach by any other party of Securities Laws or other rule of any securities regulatory authority, (b) lost profits or (c) special, indirect, incidental, consequential, exemplary, aggravated or punitive losses or damages.

(1) The Warrant Agent may resign its appointment and be discharged from all further duties and liabilities hereunder by giving to the Company not less than 60 days prior notice in writing or such shorter prior notice as the Company may accept as sufficient. The Warrantholders by extraordinary resolution shall have the power at any time to remove the existing Warrant Agent and to appoint a new Warrant Agent. In the event of the Warrant Agent 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 Warrant Agent unless a new Warrant Agent has already been appointed by the Warrantholders; failing such appointment by the Company, the retiring Warrant Agent or any Warrantholder may apply to a judge of the Province of Ontario at the Company's expense, on such notice as such judge may direct, for the appointment of a new Warrant Agent; but any new Warrant Agent so appointed by the Company or by the Court shall be subject to removal as aforesaid by the Warrantholders. Any new Warrant Agent appointed under any provision of this section 9.8 shall be a corporation authorized to carry on the business of a transfer agent or a trust company in the Province of Ontario and, if required by Applicable Legislation of any other province, in such other province. On any such appointment the new Warrant Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Warrant Agent without any further assurance, conveyance, act or deed; but there shall be immediately executed, at the expense of the Company, all such conveyances or other instruments as may, in the opinion of counsel, be necessary or advisable for the purpose of assuring the same to the new Warrant Agent, provided that any resignation or removal of the Warrant Agent and appointment of a successor Warrant Agent shall not become effective until the successor Warrant Agent shall have executed an appropriate instrument accepting such appointment and, at the request of the Company, the predecessor Warrant Agent, upon payment of its outstanding remuneration and expenses, shall execute and deliver to the successor Warrant Agent an appropriate instrument transferring to such successor Warrant Agent all rights and powers of the Warrant Agent hereunder and all securities, documents of title and other instruments and all monies and properties held by the Warrant Agent hereunder.

(2) Upon the appointment of a successor Warrant Agent, the Company shall promptly notify the Warrantholders thereof in the manner provided for in section 10.1.

(3) Any corporation into or with which the Warrant Agent may be merged or consolidated or amalgamated, or to which all or substantially all of the corporate trust business is sold or any corporation succeeding to the stock transfer business of the Warrant Agent, shall be the successor to the Warrant Agent hereunder without any further act on its part or of any of the parties hereto, provided that such corporation would be eligible for appointment as a new Warrant Agent under subsection 9.8(1).

The Warrant Agent may transfer personal information to other companies in or outside of Canada that provide data processing and storage or other support in order to facilitate the services it provides.

- 48 -

Further, the Company agrees that it shall not provide or cause to be provided to the Warrant Agent any personal information relating to an individual who is not a party to this Indenture unless that party has assured itself that such individual understands and has consented to the aforementioned uses and disclosures.

The Company represents to the Warrant Agent that any account to be opened by, or interest to be held by the Warrant Agent in connection with this Indenture, for or to the credit of such party, either (i) is not intended to be used by or on behalf of any third party; or (ii) is intended to be used by or on behalf of a third party, in which case such party hereto agrees to complete and execute forthwith a declaration in the Warrant Agent prescribed form as to the particulars of such third party.

Any matter provided herein to be determined by the directors in their sole discretion and determination so made will be conclusive.

Upon the earlier of the Time of Expiry or the date by which there shall have been delivered to the Warrant Agent for exercise or cancellation in accordance with the provisions hereof all Warrants theretofore Authenticated or certified hereunder, this Indenture, except to the extent that Warrant Shares and any certificates therefor have not been issued and delivered hereunder or the Company has not performed any of its obligations hereunder, shall cease to be of further effect in respect of the Company, and the Warrant Agent, on written demand of and at the cost and expense of the Company, and upon delivery to the Warrant Agent of a certificate of the Company stating that all conditions precedent to the satisfaction and discharge of this Indenture have been complied with and upon payment to the Warrant Agent of the expenses, fees and other remuneration payable to the Warrant Agent, shall execute proper instruments acknowledging satisfaction of and discharging this Indenture.

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

- 49 -

The Company and the Warrant Agent may deem and treat the Warrantholders as the absolute owner thereof for all purposes, and the Company and the Warrant Agent shall not be affected by any notice or knowledge to the contrary except where the Company or the Warrant Agent is required to take notice by statute or by order of a court of competent jurisdiction. The receipt of any such Warrantholder of the Warrant Shares which may be acquired pursuant thereto shall be a good discharge to the Company and the Warrant Agent for the same and neither the Company nor the Warrant Agent shall be bound to inquire into the title of any such holder except where the Company or the Warrant Agent is required to take notice by statute or by order of a court of competent jurisdiction.

To the extent of any discrepancy or inconsistency between the terms and conditions of this Indenture and the Warrant Certificate, the terms of this Indenture will prevail.

Except as provided in subsection 9.8(3), this Indenture nor any benefits or burdens under this Indenture shall be assignable by the Company or the Warrant Agent without the prior written consent of the other party, such consent not to be unreasonably withheld. Subject to the foregoing, this Indenture shall enure to the benefit of and be binding upon the Company and the Warrant Agent and their respective successors (including any successor by reason of amalgamation) and permitted assigns.

This Indenture may be simultaneously executed in several counterparts and by electronic means, each of which when so executed shall be deemed to be an original and such counterparts together shall constitute one and the same instrument and notwithstanding their date of execution shall be deemed to bear the date set out at the top of the first page of this Indenture.

No party shall be liable to the other, or held in breach of this Indenture, if prevented, hindered, or delayed in the performance or observance of any provision contained herein by reason of act of God, riots, terrorism, acts of war, epidemics, pandemics, governmental action or judicial order, earthquakes, or any other similar causes (including, but not limited to, mechanical, electronic or communication interruptions, disruptions or failures). Performance times under this Indenture shall be extended for a period of time equivalent to the time lost because of any delay that is excusable under this section.

If, in any jurisdiction, any provision of this Indenture or its application to any party or circumstance is restricted, prohibited or unenforceable, such provision will, as to such jurisdiction, be ineffective only to the extent of such restriction, prohibition or unenforceability without invalidating the remaining provisions of this Indenture and without affecting the validity or enforceability of such provision in any other jurisdiction or without affecting its application to other parties or circumstances.

- 50 -

Should a Warrantholder exercise any legal, statutory, contractual or other right of withdrawal or rescission that may be available to it, and the Warrantholder's funds which were paid on exercise have already been released to the Company by the Warrant Agent, the Warrant Agent shall not be responsible for ensuring the exercise is cancelled and a refund is paid back to the Warrantholder. In such cases, the Warrantholder shall seek a refund directly from the Company and subsequently, the Company, upon surrender to the Company or the Warrant Agent of any underlying Warrant Shares or other securities that may have been issued, or such other procedure as agreed to by the parties hereto, shall instruct the Warrant Agent in writing, to cancel the exercise transaction and any such underlying Warrant Shares or other securities on the register, which may have already been issued upon the Warrant exercise. In the event that any payment is received from the Company by virtue of the holder being a shareholder for such Warrants that were subsequently rescinded, such payment must be returned to the Company by such Warrantholder. The Warrant Agent shall not be under any duty or obligation to take any steps to ensure or enforce the return of the funds pursuant to this section, nor shall the Warrant Agent be in any other way responsible in the event that any payment is not delivered or received pursuant to this section. Notwithstanding the foregoing, in the event that the Company provides the refund to the Warrant Agent for distribution to the Warrantholder, the Warrant Agent shall return such funds to the Warrantholder as soon as reasonably practicable, and in so doing, the Warrant Agent shall incur no liability with respect to the delivery or non-delivery of any such funds.

[Warrant Indenture between Aurora Cannabis Inc. and Computershare Trust Company of Canada]

SCHEDULE A

FORM OF WARRANT CERTIFICATE

WARRANTS TO PURCHASE COMMON SHARES

OF AURORA CANNABIS INC.

(a corporation incorporated under the laws of British Columbia)

CUSIP No. 05156X165

ISIN No. CA05156X1657

THIS CERTIFIES that, for value received, the registered holder hereof, ___________________________ (the "holder") is entitled, at any time at or before 5:00 p.m. (Toronto time) on March 16, 2024 (the "Time of Expiry"), to acquire, subject to adjustment in certain events, the number of common shares ("Common Shares") of Aurora Cannabis Inc. (the "Company") specified above, as presently constituted, by surrendering to Computershare Trust Company of Canada (the "Warrant Agent") at its principal office in Vancouver, British Columbia, this Warrant Certificate with the duly completed and executed Exercise Form endorsed on the back of this Warrant Certificate, and accompanied by payment of $9.00 per Common Share (subject to adjustment in certain events) (the "Exercise Price") by certified cheque, bank draft or money order in lawful money of the United States payable to, or to the order of, the Company at par at the above-mentioned office of the Warrant Agent.

The holder of this Warrant Certificate may purchase less than the number of Common Shares which he is entitled to purchase on the exercise of the Warrants represented by this Warrant Certificate, in which event a new Warrant Certificate representing the Warrants not then exercised will be issued to the holder.

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

This Warrant Certificate represents Warrants of the Company issued or issuable under the provisions of a warrant indenture (which indenture together with all other instruments supplemental or ancillary thereto is herein referred to as the "Warrant Indenture") dated as of November 16, 2020, between the Company and the Warrant Agent, as may be amended from time to time, which contains particulars of the rights of the holders of the Warrants and the Company and of the Warrant Agent in respect thereof and the terms and conditions upon which the Warrants are issued and held, all to the same effect as if the provisions of the Warrant Indenture were herein set forth, to all of which the holder of this Warrant Certificate by acceptance hereof assents. Unless otherwise defined herein, all capitalized terms shall have the meanings ascribed to them in the Warrant Indenture. A copy of the Warrant Indenture will be available for inspection at the principal office of the Company in the City of Vancouver, British Columbia. In the event of any conflict between the provisions contained in this Warrant Certificate and the provisions of the Warrant Indenture, the provisions of the Warrant Indenture shall prevail.

A-1

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

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

Pursuant to section 4.2 of the Warrant Indenture, if at any time following the initial effectiveness of a shelf registration statement filed with the United States Securities and Exchange Commission under the U.S. Securities Act of 1933, as amended, registering the Common Shares issuable upon exercise of the Warrants (a "Registration Statement") and prior to the Time of Expiry, the Company determines that no Registration Statement filed with the United States Securities and Exchange Commission is effective, or the use of any such Registration Statement is suspended, no Warrantholder will be permitted to exercise Warrants unless an exemption from the registration requirements of the U.S. Securities Act and applicable state securities laws is available, and the Company shall promptly provide written notice of such determination to the Warrant Agent. Upon receipt of such notice, the Warrant Agent shall provide a copy thereof to each holder of Warrants, and confirm in writing that the then outstanding Warrants may, until the earlier of (x) a Registration Statement becoming effective or ceasing to be suspended and any prospectus supplement necessary in relation thereto having been filed, or (y) the Time of Expiry, if the Current Market Price exceeds the Exercise Price, also be exercised by means of a "cashless exercise" in which the holder of Warrants shall be entitled to surrender a Warrant to the Company in exchange for the issuance of the number of Common Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where: (a) (A) equals the Current Market Price on the trading day immediately preceding the date of the receipt by the Warrant Agent of the notice of exercise; (b) (B) equals the Exercise Price per Common Share of such Warrant, as adjusted; and (c) (X) equals the number of Common Shares that would otherwise be issuable upon exercise of such Warrant in accordance with its terms by means of a cash exercise rather than a cashless exercise.

A-2

The issue price for each such Common Share to be issued pursuant to the cashless exercise of a Warrant will be equal to (B), as defined above, and the total issue price for the aggregate number of Common Shares issued pursuant to the cashless exercise of a Warrant will be paid and satisfied in full by the surrender to the Company of such Warrant.

In addition, if the Company determines at any time prior to the Expiry Date that U.S. state securities laws are not preempted with respect to exercises of the Warrants, the Company may by written notice to the Warrant Agent elect to permit exercises of Warrants that are subject to the laws of one or more U.S. jurisdictions to be exercised on a "cashless exercise" basis, pursuant to the cashless exercise formula set forth above.

Upon the receipt of such notice, the Warrant Agent shall provide a copy thereof to each registered holder of Warrants, and confirm the Company's determination in writing.

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

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

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

The Warrant Indenture contains provisions making binding upon all holders of Warrants outstanding thereunder resolutions passed at meetings of such holders held in accordance with such provisions and instruments in writing signed by the Warrantholders holding a specified percentage of the then outstanding Warrants.

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

A-3

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

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

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

IN WITNESS WHEREOF the Company has caused this Warrant Certificate to be signed by its duly authorized officer as of this ____ day of ____________________, 20___.
