Each Warrant originally issued to, or for the benefit or account of, a U.S. Warrantholder will be evidenced in certificated form only and bear the applicable legends as set forth in Schedule “A” hereto. All Warrants issued in certificated form shall be evidenced by a Warrant Certificate (including all replacements issued in accordance with this Indenture), substantially in the form set out in Schedule “A” hereto, which shall be dated as of the Issue Date, shall bear such distinguishing letters and numbers as the Corporation may, with the approval of the Warrant Agent, prescribe, and shall be issuable in any denomination excluding fractions. All Warrants issued to the Depository may be in either a certificated or uncertificated form, such uncertificated form being evidenced by a book position on the register of Warrantholders to be maintained by the Warrant Agent in accordance with Section 2.6. |
|-----------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

Except as provided in this Section 2.6, owners of beneficial interests in any CDS Global Warrants shall not be entitled to have Warrants registered in their names and shall not receive or be entitled to receive Warrants in definitive form or to have their names appear in the register referred to in Section 2.9 herein. Notwithstanding any terms set out herein, Warrants having any legend set forth in Section 2.8 herein and held in the name of the Depository may only be held in the form of Uncertificated Warrants with the prior consent of the Warrant Agent and in accordance with the internal procedures of the Warrant Agent. |
|-----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (2)   | Notwithstanding any other provision in this Indenture, no CDS Global Warrants may be exchanged in whole or in part for Warrants registered, and no transfer of any CDS Global Warrants in whole or in part may be registered, in the name of any person other than the Depository for such CDS Global Warrants or a nominee thereof unless: |
|-----------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (a)   | the Depository notifies the Corporation that it is unwilling or unable to continue to act as depository in connection with the Book Entry Only Warrants and the Corporation is unable to locate a qualified successor; |
|-----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (b)   | the Corporation determines that the Depository is no longer willing, able or qualified to discharge properly its responsibilities as holder of the CDS Global Warrants and the Corporation is unable to locate a qualified successor; |
|-----------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (c)   | the Depository ceases to be a clearing agency or otherwise ceases to be eligible to be a depository and the Corporation is unable to locate a qualified successor; |
|-----------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (d)   | the Corporation determines that the Warrants shall no longer be held as Book Entry Only Warrants through the Depository; |
|-----------------|--------------------------------------------------------------------------------------------------------------------------|

| (e)   | such right is required by Applicable Law, as determined by the Corporation and the Corporation’s Counsel; |
|-----------------|-----------------------------------------------------------------------------------------------------------------|

| (f)   | the Warrant is to be Authenticated to, or for the account or benefit of, a person in the United States or a U.S. Person; or |
|-----------------|-----------------------------------------------------------------------------------------------------------------------------|

| (g)   | such registration is effected in accordance with the internal procedures of the Depository and the Warrant Agent, |
|-----------------|-------------------------------------------------------------------------------------------------------------------|

Section 2.6(2)(a)
(f)

| (3)   | Subject to the provisions of this Section 2.6, any exchange of CDS Global Warrants for Warrants which are not CDS Global Warrants may be made in whole or in part in accordance with the provisions of Section 2.11,mutatis mutandis.  All such Warrants issued in exchange for a CDS Global Warrant or any portion thereof shall be registered in such names as the Depository for such CDS Global Warrants shall direct and shall be entitled to the same benefits and be subject to the same terms and conditions (except insofar as they relate specifically to CDS Global Warrants) as the CDS Global Warrants or portion thereof surrendered upon such exchange. |
|-----------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (4)   | Every Warrant that is Authenticated upon registration or transfer of a CDS Global Warrant, or in exchange for or in lieu of a CDS Global Warrant or any portion thereof, whether pursuant to this Section 2.6, or otherwise, shall be Authenticated in the form of, and shall be, a CDS Global Warrant, unless such Warrant is registered in the name of a person other than the Depository for such CDS Global Warrant or a nominee thereof. |
|-----------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (5)   | Notwithstanding anything to the contrary in this Indenture, subject to Applicable Law, the CDS Global Warrant will be issued as an Uncertificated Warrant, unless otherwise requested in writing by the Depository or the Corporation. |
|-----------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

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

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

| (a)   | the electronic records maintained by the Depository relating to any ownership interests or any other interests in the Warrants or the depository system maintained by the Depository, or payments made on account of any ownership interest or any other interest of any person in any Warrant represented by an electronic position in the book entry registration system (other than the Depository or its nominee); |
|-----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

----

| (b)   | maintaining, supervising or reviewing any records of the Depository or any Book Entry Only Participant relating to any such interest; or |
|-----------------|------------------------------------------------------------------------------------------------------------------------------------------|

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

| (8)   | The Corporation may terminate the application of this Section 2.6 in its sole discretion in which case all Warrants shall be evidenced by Warrant Certificates registered in the name of a Person other than the Depository. |
|-----------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (1)   | For Warrants issued in certificated form, the form of certificate representing Warrants shall be substantially as set out in Schedule “A” hereto or such other form as is authorized from time to time by the Warrant Agent. Each Warrant Certificate shall be Authenticated manually on behalf of the Warrant Agent. Each Warrant Certificate shall be signed by any two duly authorized signatories of the Corporation; whose signature shall appear on the Warrant Certificate and may be printed, lithographed or otherwise mechanically reproduced thereon and, in such event, certificates so signed are as valid and binding upon the Corporation as if they had been signed manually. Any Warrant Certificate which has two signatures as hereinbefore provided shall be valid notwithstanding that one or more of the persons whose signature is printed, lithographed or mechanically reproduced no longer holds office at the date of issuance of such certificate. The Warrant Certificates may be engraved, printed or lithographed, or partly in one form and partly in another, as the Warrant Agent may determine. |
|-----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (2)   | The Warrant Agent shall Authenticate Uncertificated Warrants (whether upon original issuance, exchange, registration of transfer, partial payment, or otherwise) by completing its Internal Procedures and the Corporation shall, and hereby acknowledges that it shall, thereupon be deemed to have duly and validly issued such Uncertificated Warrants under this Indenture.  Such Authentication shall be conclusive evidence that such Uncertificated Warrant has been duly issued hereunder and that the holder or holders are entitled to the benefits of this Indenture.  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 Corporation. |
|-----------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (3)   | Any Warrant Certificate validly issued in accordance with the terms of this Indenture in effect at the time of issue of such Warrant Certificate shall, subject to the terms of this Indenture and applicable law, validly entitle the holder to acquire Common Shares, notwithstanding that the form of such Warrant Certificate may not be in the form currently required by this Indenture.  |
|-----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

----

| (4)   | No Warrant shall be considered issued and shall be valid or obligatory or shall entitle the holder thereof to the benefits of this Indenture, until it has been Authenticated by the Warrant Agent. Authentication by the Warrant Agent, including by way of entry on the register,  shall not be construed as a representation or warranty by the Warrant Agent as to the validity of this Indenture or of such Warrant Certificates or Uncertificated Warrants (except the due Authentication thereof) or as to the performance by the Corporation of its obligations under this Indenture and the Warrant Agent shall in no respect be liable or answerable for the use made of the Warrants or any of them or of the consideration thereof. Authentication by the Warrant Agent shall be conclusive evidence as against the Corporation that the Warrants so Authenticated have been duly issued hereunder and that the holder thereof is entitled to the benefits of this Indenture. |
|-----------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (5)   | No Certificated Warrant shall be considered issued and Authenticated or, if Authenticated, shall be obligatory or shall entitle the holder thereof to the benefits of this Indenture, until it has been Authenticated by manual signature by or on behalf of the Warrant Agent substantially in the form of the Warrant set out in Schedule “A” hereto. Such Authentication on any such Certificated Warrant shall be conclusive evidence that such Certificated Warrant is duly Authenticated and is valid and a binding obligation of the Corporation and that the holder is entitled to the benefits of this Indenture. |
|-----------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (6)   | No Uncertificated Warrant shall be considered issued and shall be obligatory or shall entitle the holder thereof to the benefits of this Indenture, until it has been Authenticated by entry on the register of the particulars of the Uncertificated Warrant. Such entry on the register of the particulars of an Uncertificated Warrant shall be conclusive evidence that such Uncertificated Warrant is a valid and binding obligation of the Corporation and that the holder is entitled to the benefits of this Indenture. |
|-----------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (7)   | The Authentication by the Warrant Agent of any Warrants whether by way of entry on the register or otherwise shall not be construed as a representation or warranty by the Warrant Agent as to the validity of the Indenture or such Warrants (except the due Authentication thereof) or as to the performance by the Corporation of its obligations under this Indenture and the Warrant Agent shall in no respect be liable or answerable for the use made of the Warrants or any of them or the proceeds thereof. |
|-----------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (1)   | Neither the Warrants nor the Common Shares issuable upon exercise of the Warrants have been or will be registered under the U.S. Securities Act or under any  state securities laws of the United States.  Each Warrant Certificate originally issued to, or for the benefit or account of, a U.S. Warrantholder and each Warrant Certificate issued in exchange therefor or in substitution thereof shall bear or be deemed to bear the following legends or such variations thereof as the Corporation may prescribe from time to time: |
|-----------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (2)   | Each CDS Global Warrant originally issued in Canada and held by the Depository, and each CDS Global Warrant issued in exchange therefor or in substitution thereof shall bear or be deemed to bear the following legend or such variations thereof as the Corporation may prescribe from time to time: |
|-----------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (3)   | Each Certificated Warrant originally issued in Canada or to a Canadian holder and each CDS Global Warrant originally issued in Canada and held by the Depository on the date hereof (and each such Certificated Warrant or CDS Global Warrant, as the case may be, issued in exchange therefore or in substitution thereof prior to the date that is four months and a day after the date hereof) shall bear or be deemed to bear the following legend or such variations thereof  as the Corporation my prescribe from time to time: |
|-----------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

----

| (4)   | Notwithstanding any other provisions of this Indenture, in processing and registering transfers of Warrants, no duty or responsibility whatsoever shall rest upon the Warrant Agent to determine the compliance by any transferor or transferee with the terms of the legend contained in Section 2.8(1) or Section 2.8(2), or with the relevant securities laws or regulations, including, without limitation, Regulation S, and the Warrant Agent shall be entitled to assume that all transfers are legal and proper. |
|-----------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (1)   | The Warrant Agent shall maintain records and accounts concerning the Warrants, whether certificated or uncertificated, which shall contain the information called for below with respect to each Warrant, together with such other information as may be required by law or as the Warrant Agent may elect to record. All such information shall be kept in one set of accounts and records which the Warrant Agent shall designate (in such manner as shall permit it to be so identified as such by an unaffiliated party) as the register of the holders of Warrants.  The information to be entered for each account in the register of Warrants at any time shall include (without limitation): |
|-----------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (a)   | the name and address of the holder of the Warrants, the date of Authentication thereof and the number of Warrants; |
|-----------------|--------------------------------------------------------------------------------------------------------------------|

| (b)   | whether such Warrant is a Certificated Warrant or an Uncertificated Warrant and, if a Warrant Certificate, the unique number or code assigned to and imprinted thereupon and, if an Uncertificated Warrant, the unique number or code assigned thereto if any; |

|   | exercise form (the “Exercise Notice”) attached to the Warrant Certificate(s) which form is attached hereto as Schedule “B”, which may be amended by the Corporation with the consent of the Warrant Agent, if such amendment does not, in the reasonable opinion of the Corporation and the Warrant Agent, which may be based on the advice of Counsel, materially and adversely affect the rights, entitlements and interests of the Warrantholders, and deliver such certificate(s), the executed Exercise Notice and a certified cheque, bank draft or money order payable to or to the order of the Corporation for the aggregate Exercise Price to the Warrant Agent at the Warrant Agency. The Warrants represented by a Warrant Certificate shall be deemed to be surrendered upon personal delivery of such certificate, Exercise Notice and aggregate Exercise Price or, if such documents are sent by mail or other means of transmission, upon actual receipt thereof by the Warrant Agent at the office referred to above. |
|--------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (2)   | In addition to completing the Exercise Form attached to the Warrant Certificate(s), a Warrantholder who is a person in the United States, a U.S. Person, a person exercising for the account or benefit of a U.S. Person, or person requesting delivery of the Common Shares issuable upon exercise of the Warrants in the United States must (a) provide a completed and executed U.S. Purchaser Letter or (b) an opinion of counsel of recognised standing in form and substance reasonably satisfactory to the Corporation that the exercise is exempt from the registration requirements of the U.S. Securities Act and applicable securities laws of any state of the United States ; provided however that in the case of a Warrantholder that is the original purchaser of Warrants and who delivered the U.S. Accredited Investor Certificate attached to the subscription agreement of the Corporation in connection with its purchase of Units pursuant to the private placement under which the Warrants were issued, such Warrantholder will not be required to deliver a U.S. Purchaser Letter or an opinion of counsel in connection with the due exercise of the Warrant at a time when the representations, warranties and covenants made by the Warrantholder in the U.S. Accredited Investor Certificate and subscription agreement remain true and correct and the Warrantholder  represents to the Corporation as such. |

|   |  Depository. Forthwith upon receipt by the Depository of such notice, as well as payment for the aggregate Exercise Price, the Depository shall deliver to the Warrant Agent confirmation of its intention to exercise Warrants (a “Confirmation”) in a manner acceptable to the Warrant Agent, including by electronic means through a book based registration system, including CDSX. An electronic exercise of the Warrants initiated by the Book Entry Only Participant through a book based registration system, including CDSX, shall constitute a representation to both the Corporation and the Warrant Agent that the beneficial owner at the time of exercise of such Warrants (a) is not in the United States; (b) is not a U.S. Person and is not exercising such Warrants on behalf of a U.S. Person or a person in the United States; and (c) did not execute or deliver the notice of the owner’s intention to exercise such Warrants in the United States. If the CDS Participant is not able to make or deliver the foregoing representation by initiating the electronic exercise of the Warrants, then such Warrants shall be withdrawn from the book based registration system, including CDSX  by the CDS Participant and an individually registered Warrant Certificate shall be issued by the Warrant Agent to such Beneficial Owner or CDS Participant and the exercise procedures set forth in Section 3.2(1) shall be followed. |

| (5)   | Payment representing the aggregate Exercise Price must be provided to the appropriate office of the Book Entry Only Participant in a manner acceptable to it. A notice in form acceptable to the Book Entry Only Participant and payment from such beneficial holder should be provided to the Book Entry Only Participant sufficiently in advance so as to permit the Book Entry Only Participant to deliver notice and payment to the Depository and for the Depository in turn to deliver notice and payment to the Warrant Agent prior to Expiry Time. The Depository will initiate the exercise by way of the Confirmation and forward the aggregate Exercise Price electronically to the Warrant Agent and the Warrant Agent will execute the exercise by issuing to the Depository through the book entry registration system the Common 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 Book Entry Only Participant exercising the Warrants on its behalf. |

| (6)   | By causing a Book Entry Only Participant to deliver notice to the Depository, a Warrantholder shall be deemed to have irrevocably surrendered his or her Warrants so exercised and appointed such Book Entry Only Participant to act as his or her exclusive settlement agent with respect to the exercise and the receipt of Common Shares in connection with the obligations arising from such exercise. |
|-----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (7)   | Any notice which the Depository 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 Book Entry Only Participant to exercise or to give effect to the settlement thereof in accordance with the Warrantholder’s instructions will not give rise to any obligations or liability on the part of the Corporation or Warrant Agent to the Book Entry Only Participant or the Warrantholder. |

|-----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (9)   | Any exercise referred to in this Section 3.2 shall require that the entire Exercise Price for Common Shares subscribed must be paid at the time of subscription and such Exercise Price and original Exercise Notice executed by the Registered Warrantholder or the Confirmation from the Depository must be received by the Warrant Agent prior to the Expiry Time. |

| (13)   | Any Warrant with respect to which a Confirmation 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. |

Upon any adjustment of the Exercise Price pursuant to this Section 4.1(c), the Exchange Rate will be adjusted immediately after such record date so that it will equal the rate determined by multiplying the Exchange Rate in effect on such record date by a fraction, of which the numerator shall be the Exercise Price in effect immediately prior to such adjustment and the denominator shall be the Exercise Price resulting from such adjustment; |
