NOBILIS HEALTH CORP. as the Corporation and CST TRUST COMPANY as the Warrant Agent

Subject to the applicable conditions for exercise set out in Article 3 having been satisfied, subject to adjustment in accordance with Section 4.1, and subject to acceleration of the Expiry Date in accordance with Section 2.2, each Warrant shall entitle each Warrantholder thereof, upon exercise at any time after the Issue Date and prior to the Expiry Time, to acquire one (1) Common Share upon payment of the Exercise Price.

No fractional Warrants shall be issued or otherwise provided for hereunder and Warrants may only be exercised in a sufficient number to acquire whole numbers of Common Shares.

Each Warrant shall entitle the holder thereof to such other rights and privileges as are set forth in this Indenture.

The number of Common Shares which may be purchased pursuant to the Warrants and the Exercise Price therefor shall be adjusted upon the events and in the manner specified in Section 4.1.

After the Restrictive Period, reregistration of beneficial interests in and transfers of Warrants held by the Depository may be made through the book entry registration system. Except as provided in this Section 2.7, 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 2.10 herein. Notwithstanding any terms set out herein, Warrants having any legend set forth in Section 2.9 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.

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:

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;

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;

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;

the Corporation determines that the Warrants shall no longer be held as Book Entry Only Warrants through the Depository;

such right is required by applicable law, as determined by the Corporation and the

Corporation’s Counsel;

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

such registration is effected in accordance with the internal procedures of the Depository and the Warrant Agent, following which, Warrants for those holders requesting the same shall be registered and issued to the beneficial owners of such Warrants or their nominees as directed by the holder. The Corporation shall provide an officer’s certificate giving notice to the Warrant Agent of the occurrence of any event outlined in this Section 2.7(2)(a) to (f).

Subject to the provisions of this Section 2.7, 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 2.12, 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 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.

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 2.7, 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.

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.

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.

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

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);

maintaining, supervising or reviewing any records of the Depository or any Book Entry Only Participant relating to any such interest; or

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.

The Corporation may terminate the application of this Section 2.7 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.

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 one duly authorized signatory 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 it had been signed manually. Any Warrant Certificate which has one signature as hereinbefore provided shall be valid notwithstanding that the person 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.

After the Restricted Period, the Warrant Agent shall Authenticate Uncertificated Warrants (whether upon 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.

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.

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.

No Certificated Warrant shall be considered issued and Authenticated or 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.

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.

Notwithstanding anything herein contained, Warrants and Common Shares will only be issued pursuant to the transfer or exercise of any Warrant in compliance with Applicable Legislation of any applicable jurisdiction and, without limiting the generality of the foregoing, in respect of any Warrants transferred or exercised for Common Shares the certificates representing the issued Warrants or Common Shares, as the case may be, will bear such legends as may, in the opinion of Counsel to the Corporation, be necessary in order to avoid a violation of Applicable Legislation of such jurisdiction or to comply with the requirements of any stock exchange on which the Common Shares are listed, provided that if, at any time, in the opinion of Counsel to the Corporation, such legends are no longer necessary in order to avoid a violation of any such laws, or the holder of any such legended certificate, at the holder’s expense, provides the Corporation with evidence satisfactory in form and substance to the Corporation (which may include an opinion of counsel satisfactory to the Corporation) to the effect that such holder is entitled to sell or otherwise transfer such Warrants or Common Shares, as the case may be, in a transaction in which such legends are not required, such legended certificate may thereafter be surrendered to the Special Warrant Agent in exchange for a certificate which does not bear such legend.

After the Restrictive Period, each CDS Global Warrant originally issued in Canada pursuant to the Offering and held by the Depository, and each such CDS Global Warrant, as the case may be, issued in exchange therefor or in substitution thereof shall bear the following legend or such variations thereof as the Corporation may prescribe from time to time:

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 2.9(1), 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.

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):

the name and address of the holder of the Warrants, the date of Authentication thereof and the number Warrants;

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

whether such Warrant has been cancelled; and

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

Once an Uncertificated Warrant has been Authenticated, the information set forth in the register with respect thereto at the time of Authentication may be altered, modified, amended, supplemented or otherwise changed only to reflect exercise or proper instructions to the Warrant Agent from the holder as provided herein, except that the Warrant Agent may act unilaterally to make purely administrative changes internal to the Warrant Agent and changes to correct errors. Each person who becomes a holder of an Uncertificated Warrant, by his, her or its acquisition thereof shall be deemed to have irrevocably consented to the foregoing authority of the Warrant Agent to make such error corrections.

If any Warrant Certificate becomes mutilated or is lost, destroyed or stolen, the Corporation, subject to applicable law, shall issue and thereupon the Warrant Agent shall certify and deliver, a new Warrant Certificate of like tenor, and bearing the same legend, if applicable, as the one mutilated, lost, destroyed or stolen in exchange for and in place of and upon cancellation of such mutilated Warrant Certificate, or in lieu of and in substitution for such lost, destroyed or stolen Warrant Certificate, and the substituted Warrant Certificate shall be in a form approved by the Warrant Agent and the Warrants evidenced thereby shall be entitled to the benefits hereof and shall rank equally in accordance with its terms with all other Warrants issued or to be issued hereunder.

The applicant for the issue of a new Warrant Certificate pursuant to this Section 2.11 shall bear the cost of the issue thereof and in case of loss, destruction or theft shall, as a condition precedent to the issuance thereof, furnish to the Corporation and to the Warrant Agent such evidence of ownership and of the loss, destruction or theft of the Warrant Certificate so lost, destroyed or stolen as shall be satisfactory to the Corporation and to the Warrant Agent, in their sole discretion, and such applicant shall also be required to furnish an indemnity and surety bond in amount and form satisfactory to the Corporation and the Warrant Agent, in their sole discretion, and shall pay the reasonable charges of the Corporation and the Warrant Agent in connection therewith.

Any one or more Warrant Certificates representing any number of Warrants may, upon compliance with the reasonable requirements of the Warrant Agent (including compliance with Applicable Legislation), be exchanged for one or more other Warrant Certificates representing the same aggregate number of Warrants, and bearing the same legend, if applicable, as represented by the Warrant Certificate or Warrant Certificates so exchanged.

Warrant Certificates may be exchanged only at the Warrant Agency or at any other place that is designated by the Corporation with the approval of the Warrant Agent. Any Warrant Certificate from the holder (or such other instructions, in form satisfactory to the Warrant Agent), tendered for exchange shall be surrendered to the Warrant Agency and cancelled by the Warrant Agent.

Warrant Certificates exchanged for Warrant Certificates that bear the legends set forth in Section 2.9(1) shall bear the same legends.

The Warrants may only be transferred on the register kept by the Warrant Agent at the Warrant Agency by the holder or its legal representatives or its attorney duly appointed by an instrument in writing in form and execution satisfactory to the Warrant Agent only upon (a) in the case of a Warrant Certificate, surrendering to the Warrant Agent at the Warrant Agency the Warrant Certificate representing the Warrants to be transferred together with a duly executed transfer form as set forth in Schedule A and (b) in the case of Book Entry Only Warrants, in accordance with procedures prescribed by the Depository under the book entry registration system, and (c) upon compliance with:

the conditions herein;

such reasonable requirements as the Warrant Agent may prescribe; and

all Applicable Legislation and requirements of regulatory authorities;

Subject to the provisions of this Indenture, Applicable Legislation and applicable law, the Warrantholder shall be entitled to the rights and privileges attaching to the Warrants, and the issue of Common Shares by the Corporation upon the exercise of Warrants in accordance with the terms and conditions herein contained shall discharge all responsibilities of the Corporation and the Warrant Agent with respect to such Warrants and neither the Corporation nor the Warrant Agent shall be bound to inquire into the title of any such holder.

Registered Warrantholders of Warrant Certificates who wish to exercise the Warrants held by them in order to acquire Common Shares must complete the exercise form (the “Exercise Notice”) attached to the Warrant Certificate(s), 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 Warrant Agent 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 Warrant Agency.

In addition to completing the Exercise Notice 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 a person in the United States, or person requesting delivery of the Common Shares issuable upon exercise of the Warrants in the United States must provide (a) a completed and executed U.S. Purchaser Certification or (b) an opinion of counsel of recognised standing in form and substance reasonably satisfactory to the Corporation and the Warrant Agent that the exercise is exempt from the registration requirements of applicable securities laws of any state of the United States and the U.S. Securities Act; 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 Treasury Units pursuant to the private placement under which the Warrants were issued, such Warrantholder will not be required to deliver a U.S. Purchaser Certification or an opinion of counsel in connection with the due exercise of the Warrants at a time when the representations, warranties and covenants made by the Warrantholder in the U.S. accredited investor certificate remain true and correct and the Warrantholder represents to the Corporation as such.

A beneficial holder of Uncertificated Warrants evidenced by a security entitlement in respect of Warrants in the book entry registration system who desires to exercise his or her Warrants must do so by causing a Book Entry Only Participant to deliver to the Depository on behalf of the entitlement holder, notice of the owner’s intention to exercise Warrants in a manner acceptable to the 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 (“Confirmation”) in a manner acceptable to the Warrant Agent, including by electronic means through the book entry registration system, and shall electronically confirm that the beneficial holder (a) at the time of exercise of the Warrants is not in the United States; (b) is not a U.S. Person and is not exercising the Warrants for the account or benefit of a U.S. Person or a person in the United States; and (c) did not execute or deliver the Confirmation in the United States.

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.

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.

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.

Any exercise form or Exercise Notice referred to in this Section 3.2 shall be signed by the Registered Warrantholder, or its executors or administrators or other legal representatives or an attorney of the Registered Warrantholder, duly appointed by an instrument in writing satisfactory to the Warrant Agent but such exercise form need not be executed by the Depository.

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, Certificated Warrant and original Exercise Notice executed by the Registered Warrantholder or the Confirmation from the Depository, as applicable, must be received by the Warrant Agent prior to the Expiry Time.

Warrants may only be exercised pursuant to this Section 3.2 by or on behalf of a Registered Warrantholder who makes the certifications set forth on the Exercise Notice set out in Schedule B or as provided herein.

If the form of Exercise Notice set forth in the Warrant Certificate shall have been amended, the Corporation shall cause the amended Exercise Notice to be forwarded to all Registered Warrantholders.

Exercise Notices and Confirmations and the payment of the aggregate Exercise Price 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 Notice, Confirmation or payment delivered to 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.

Subject to Section 3.3(2) and Section 3.3(3) below, (a) Warrants may not be exercised within the United States, by any U.S. Person, or for the account or benefit of any U.S. Person or any person in the United States; and (b) no Common Shares issued upon exercise of Warrants may be delivered to any address in the United States.

Notwithstanding Section 3.3(1), Warrants may be exercised in the United States, by a U.S. Person, or for the account or benefit of a U.S. Person or a person in the United States, and Common Shares issued upon exercise of any such Warrants may be delivered to an address in the United States, provided that (a) the Person exercising the Warrants (i) is an original U.S. Purchaser who purchased the Warrants directly from the Corporation, or (ii) is an "accredited investor" that satisfies one or more of the criteria set forth in Rule 501(a) of Regulation D and (b) delivers a completed and executed U.S. Purchaser Certification or provides in form and substance satisfactory to the Corporation and Warrant Agent a legal opinion which confirms that the issuance of the Common Shares is in compliance with the applicable state laws and the U.S. Securities Act; provided however that in the case of a Warrantholder that is the original purchaser of the Warrants and who delivered the U.S. accredited investor certificate attached to the subscription agreement of the Corporation in connection with its purchase of Treasury Units pursuant to the private placement under which the Warrants were issued, such Warrantholder will not be required to deliver a U.S. Purchaser Certification 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 remain true and correct and the Warrantholder represents to the Corporation as such.

Unless the Corporation has previously caused a registration statement on Form S-1 to be declared effective by the SEC, which registers the issuance of Common Shares upon exercise of Warrants, certificates representing Common Shares issued upon the exercise of Warrants (and Warrants issued in substitution or exchange therefor) shall bear the following legend:

Certificates representing Common Shares issued upon exercise of Warrants (and Warrants issued in substitution or exchange therefor) prior to the date that is four months and one day after the Issue Date shall, in addition to the legend set forth in Section 3.3(3), also bear the following legends:

Upon the exercise of Warrants pursuant to and in compliance with Section 3.2 and subject to Section 3.3 and Section 3.4, the Common Shares to be issued pursuant to the Warrants exercised shall be deemed to have been issued and the person or persons to whom such Common Shares are to be issued shall be deemed to have become the holder or holders of such Common Shares on the day of receipt by the Warrant Agent of a duly completed Exercise Notice and the aggregate Exercise Price, unless the register shall be closed on such date, in which case the Common Shares subscribed for shall be deemed to have been issued and such person or persons deemed to have become the holder or holders of record of such Common Shares, on the date on which such register is reopened.

Within five Business Days after the Exercise Date with respect to a Warrant, the Warrant Agent shall cause to be delivered or mailed to the person or persons in whose name or names the Warrant is registered or, if so specified in writing by the holder, cause to be delivered to such person or persons at the Warrant Agency where the Warrant Certificate was surrendered, a certificate or certificates for the appropriate number of Common Shares subscribed for, or any other appropriate evidence of the issuance of Common Shares to such person or persons in respect of Common Shares issued under the book entry registration system.

The holder of any Warrants may exercise his right to acquire a number of whole Common Shares that is less than the aggregate number which the holder is entitled to acquire. In the event of any exercise of a number of Warrants that is less than the number which the holder is entitled to exercise, the holder of Warrants upon such exercise shall, in addition, be entitled to receive, without charge therefor, a new Warrant Certificate(s), bearing the same legends, if applicable, or other appropriate evidence of Warrants, in respect of the balance of the Warrants held by such holder and which were not then exercised.

Notwithstanding anything herein contained, including any adjustment provided for in Article 4, the Corporation shall not be required, upon the exercise of any Warrants, to issue fractions of Common Shares. Warrants may only be exercised in a sufficient number to acquire whole numbers of Common Shares. Any subscription for fractional Common Shares will be deemed to be a subscription for the closest whole number of Common Shares rounding down, and no cash or other consideration will be paid in lieu of fractional shares.

The Warrant Agent shall promptly account to the Corporation with respect to Warrants exercised, and shall promptly forward to the Corporation (or into an account or accounts of the Corporation with the bank or trust company designated by the Corporation for that purpose), all monies received by the Warrant Agent on the subscription of Common Shares through the exercise of Warrants. All such monies and any securities or other instruments, from time to time received by the Warrant Agent, shall be received in trust for, and shall be segregated and kept apart by the Warrant Agent, the Warrantholders and the Corporation as their interests may appear

The Warrant Agent shall record the particulars of Warrants exercised, which particulars shall include the names and addresses of the persons who become holders of Common Shares on exercise and the Exercise Date, in respect thereof. The Warrant Agent shall provide such particulars in writing to the Corporation within five Business Days of any request by the Corporation therefor.

if, at any time during the Adjustment Period, the Corporation shall:

subdivide, re-divide or change its outstanding Common Shares into a greater number of Common Shares;

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

issue Common Shares or securities exchangeable for, or convertible into, Common Shares to all or substantially all of the holders of Common Shares by way of stock dividend or other distribution (other than a dividend paid in the ordinary course, or a distribution of Common Shares upon the exercise of Warrants or any outstanding options);

if and whenever at any time during the Adjustment Period, the Corporation shall fix a record date for the issuance of rights, options or warrants to all or substantially all the holders of its outstanding Common Shares entitling them, for a period expiring not more than 45 days after such record date, to subscribe for or purchase Common Shares (or securities convertible or exchangeable into Common Shares) at a price per Common Share (or having a conversion or exchange price per Common Share) less than 95% of the Current Market Price on such record date (a “Rights Offering”), the Exercise Price shall be adjusted immediately after such record date so that it shall equal the amount determined by multiplying the Exercise Price in effect on such record date by a fraction, of which the numerator shall be the total number of Common Shares outstanding on such record date plus a number of Common Shares equal to the number arrived at by dividing the aggregate price of the total number of additional Common Shares offered for subscription or purchase (or the aggregate conversion or exchange price of the convertible or exchangeable securities so offered) by the Current Market Price, and of which the denominator shall be the total number of Common Shares outstanding on such record date plus the total number of additional Common Shares offered for subscription or purchase or into which the convertible or exchangeable securities so offered are convertible or exchangeable; any Common Shares owned by or held for the account of the Corporation shall be deemed not to be outstanding for the purpose of any such computation; such adjustment shall be made successively whenever such a record date is fixed; to the extent that no such rights or warrants are exercised prior to the expiration thereof, the Exercise Price shall be readjusted to the Exercise Price which would then be in effect if such record date had not been fixed or, if any such rights or warrants are exercised, to the Exercise Price which would then be in effect based upon the number of Common Shares (or securities convertible or exchangeable into Common Shares) actually issued upon the exercise of such rights or warrants, as the case may be. Upon any adjustment of the Exercise Price pursuant to this Section 4.1(b), 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. Such adjustment will be made successively whenever such a record date is fixed, provided that if two or more such record dates referred to in this Section 4.1(b) are fixed within a period of 25 Trading Days, such adjustment will be made successively as if each of such record dates occurred on the earliest of such record dates;

if and whenever at any time during the Adjustment Period the Corporation shall fix a record date for the making of a distribution to all or substantially all the holders of its outstanding Common Shares of (i) securities of any class, whether of the Corporation or any other entity(other than Common Shares), (ii) rights, options or warrants to subscribe for or purchase Common Shares (or other securities convertible into or exchangeable for Common Shares), other than pursuant to a Rights Offering; (iii) evidences of its indebtedness or (iv) any property or other assets then, in each such case, the Exercise Price shall be adjusted immediately after such record date so that it shall equal the price determined by multiplying the Exercise Price in effect on such record date by a fraction, of which the numerator shall be the total number of Common Shares outstanding on such record date multiplied by the Current Market Price on such record date, less the excess, if any, of the fair market value on such record date, as determined by the Corporation (whose determination shall be conclusive), of such securities or other assets so issued or distributed over the fair market value of any consideration received therefor by the Corporation from the holders of the Common Shares, and of which the denominator shall be the total number of Common Shares outstanding on such record date multiplied by the Current Market Price; and Common Shares owned by or held for the account of the Corporation shall be deemed not to be outstanding for the purpose of any such computation; such adjustment shall be made successively whenever such a record date is fixed; to the extent that such distribution is not so made, the Exercise Price shall be readjusted to the Exercise Price which would then be in effect if such record date had not been fixed. 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;

if and whenever at any time during the Adjustment Period, there is a reclassification of the Common Shares or a capital reorganization of the Corporation other than as described in Section 4.1(a), or a consolidation, amalgamation, arrangement or merger of the Corporation with or into any other body corporate, trust, partnership or other entity, or a sale or conveyance of the property and assets of the Corporation as an entirety or substantially as an entirety to any other body corporate, trust, partnership or other entity, any Warrantholder who has not exercised its Warrants prior to the effective date of such reclassification, capital reorganization, consolidation, amalgamation, arrangement or merger, sale or conveyance, upon the exercise of such right thereafter, shall be entitled to receive upon payment of the Exercise Price and shall accept, in lieu of the number of Common Shares that prior to such effective date the Warrantholder would have been entitled to receive, the number of shares or other securities or property of the Corporation or of the body corporate, trust, partnership or other entity resulting from such merger, amalgamation or consolidation, or to which such sale or conveyance may be made, as the case may be, that such Warrantholder would have been entitled to receive on such reclassification, capital reorganization, consolidation, amalgamation, arrangement or merger, sale or conveyance, if, on the effective date thereof, as the case may be, the Warrantholder had been the registered holder of the number of Common Shares to which prior to such effective date it was entitled to acquire upon the exercise of the Warrants. If determined appropriate by the Warrant Agent, relying on advice of Counsel, to give effect to or to evidence the provisions of this Section 4.1(d), the Corporation, its successor, or such purchasing body corporate, partnership, trust or other entity, as the case may be, shall, prior to or contemporaneously with any such reclassification, capital reorganization, consolidation, amalgamation, arrangement, merger, sale or conveyance, enter into an indenture which shall provide, to the extent possible, for the application of the provisions set forth in this Indenture with respect to the rights and interests thereafter of the Warrantholders to the end that the provisions set forth in this Indenture shall thereafter correspondingly be made applicable, as nearly as may reasonably be, with respect to any shares, other securities or property to which a Warrantholder is entitled on the exercise of its acquisition rights thereafter. Any indenture entered into between the Corporation and the Warrant Agent pursuant to the provisions of this Section 4.1(d) shall be a supplemental indenture entered into pursuant to the provisions of Article 8 hereof. Any indenture entered into between the Corporation, any successor to the Corporation or such purchasing body corporate, partnership, trust or other entity and the Warrant Agent shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided in this Section 4.1 and which shall apply to successive reclassifications, capital reorganizations, amalgamations, consolidations, mergers, sales or conveyances;

in any case in which this Section 4.1 shall require that an adjustment shall become effective immediately after a record date for an event referred to herein, the Corporation may defer, until the occurrence of such event, issuing to the Warrantholder of any Warrant exercised after the record date and prior to completion of such event the additional Common Shares issuable by reason of the adjustment required by such event before giving effect to such adjustment; provided, however, that the Corporation shall deliver to such Warrantholder an appropriate instrument evidencing such Warrantholder’s right to receive such additional Common Shares upon the occurrence of the event requiring such adjustment and the right to receive any distributions made on such additional Common Shares declared in favour of holders of record of Common Shares on and after the relevant date of exercise or such later date as such Warrantholder would, but for the provisions of this Section 4.1(e), have become the holder of record of such additional Common Shares pursuant to Section 4.1;

in any case in which Section 4.1(a)(iii), Section 4.1(b) or Section 4.1(c) require that an adjustment be made to the Exercise Price, no such adjustment shall be made if the Warrantholders of the outstanding Warrants receive, subject to any required stock exchange or regulatory approval, the rights or warrants referred to in Section 4.1(a)(iii), Section 4.1(b) or the shares, rights, options, warrants, evidences of indebtedness or assets referred to in Section 4.1(c), as the case may be, in such kind and number as they would have received if they had been holders of Common Shares on the applicable record date or effective date, as the case may be, by virtue of their outstanding Warrant having then been exercised into Common Shares at the Exercise Price in effect on the applicable record date or effective date, as the case may be;

the adjustments provided for in this Section 4.1 are cumulative, and shall, in the case of adjustments to the Exercise Price be computed to the nearest whole cent and shall apply to successive subdivisions, re-divisions, reductions, combinations, consolidations, distributions, issues or other events resulting in any adjustment under the provisions of this Section 4.1, provided that, notwithstanding any other provision of this Section 4.1, no adjustment of the Exercise Price shall be required unless such adjustment would require an increase or decrease of at least 1% in the Exercise Price then in effect; provided, however, that any adjustments which by reason of this Section 4.1(g) are not required to be made shall be carried forward and taken into account in any subsequent adjustment; and

after any adjustment pursuant to this Section 4.1, the term “Common Shares” where used in this Indenture shall be interpreted to mean securities of any class or classes which, as a result of such adjustment and all prior adjustments pursuant to this Section 4.1, the Warrantholder is entitled to receive upon the exercise of his Warrant, and the number of Common Shares indicated by any exercise made pursuant to a Warrant shall be interpreted to mean the number of Common Shares or other property or securities a Warrantholder is entitled to receive, as a result of such adjustment and all prior adjustments pursuant to this Section 4.1, upon the full exercise of a Warrant.

The Warrant Agent shall not:

at any time be under any duty or responsibility to any Warrantholder to determine whether any facts exist which may require any adjustment contemplated by Section 4.1, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed in making the same;

be accountable with respect to the validity or value (or the kind or amount) of any Common Shares or of any other securities or property which may at any time be issued or delivered upon the exercise of the rights attaching to any Warrant;

be responsible for any failure of the Corporation to issue, transfer or deliver Common Shares or certificates for the same upon the surrender of any Warrants for the purpose of the exercise of such rights or to comply with any of the covenants contained in this Article 4; and

incur any liability or be in any way responsible for the consequences of any breach on the part of the Corporation of any of the representations, warranties or covenants herein contained or of any acts of the directors, officers, employees, agents or servants of the Corporation.

The Warrant Agent shall be entitled to act and rely on any adjustment calculation of the Corporation/Directors or the Corporation auditors.

The Corporation covenants with the Warrant Agent that so long as any Warrants remain outstanding:

it will reserve and keep available a sufficient number of Common Shares for the purpose of enabling it to satisfy its obligations to issue Common Shares upon the exercise of the Warrants;

it will cause the Common Shares from time to time acquired pursuant to the exercise of the Warrants to be duly issued and delivered in accordance with the Warrants and the terms hereof;

all Common Shares which shall be issued upon exercise of the right to acquire provided for herein shall be fully paid and non-assessable;

the Corporation will cause the Warrant Agent to keep open the registers of transfers referred to in Section 2.9 as required by such Section and will not take any action or omit to take any action which would have the effect of preventing the Warrantholders from exercising any of the Warrants or receiving any Common Shares underlying the Warrants upon such exercise;

it will use reasonable commercial efforts to maintain its existence and carry on its business in the ordinary course;

it will use reasonable commercial efforts to ensure that all Common Shares outstanding or issuable from time to time (including without limitation the Common Shares issuable on the exercise of the Warrants) continue to be or are listed and posted for trading on the TSX (or such other Canadian stock exchange acceptable to the Corporation) and the NYSE MKT, provided that this clause shall not be construed as limiting or restricting the Corporation to agree to a consolidation, amalgamation, arrangement, takeover bid or merger even if the consideration being offered are not securities that are so listed and posted for trading;

it will make all requisite filings under applicable Canadian and U.S. securities legislation in a timely manner, including those necessary in Canada to remain a reporting issuer not in default in each of the provinces and other Canadian jurisdictions where it is or becomes a reporting issuer;

generally, it will well and truly perform and carry out all of the acts or things to be done by it as provided in this Indenture; and

the Corporation will promptly notify the Warrant Agent and the Warrantholders in writing of any default under the terms of this Warrant Indenture which remains unrectified for more than five days following its occurrence.

Upon the happening of any default hereunder:

the Registered Warrantholders of not less than 51% of the Warrants then outstanding shall have power (in addition to the powers exercisable by Extraordinary Resolution) by requisition in writing to instruct the Warrant Agent to waive any default hereunder and the Warrant Agent shall thereupon waive the default upon such terms and conditions as shall be prescribed in such requisition; or

the Warrant Agent shall have power to waive any default hereunder upon such terms and conditions as the Warrant Agent may deem advisable, on the advice of Counsel, if, in the Warrant Agent’s opinion, based on the advice of Counsel, the same shall have been cured or adequate provision made therefor;

Section 7.6

On every Extraordinary Resolution, and on any other question submitted to a meeting and after a vote by show of hands when demanded by the chairman or by one or more of the Registered Warrantholders acting in person or by proxy and holding at least 5% of the aggregate number of Warrants then outstanding, 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 Registered Warrantholder or as proxy for one or more absent Registered Warrantholders, or both, shall have one vote. On a poll, each Registered 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 Warrant then held or represented by it. A proxy need not be a Registered 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.

The Warrant Agent, or the Corporation with the approval of the Warrant Agent, may from time to time make and from time to time vary such regulations as it shall think fit for the setting of the record date for a meeting for the purpose of determining Registered Warrantholders entitled to receive notice of and to vote at the meeting.

The Warrant Agent, or the Corporation with the approval of the Warrant Agent, may set these regulations:

Deposit of instruments appointing proxies at such place and time as the Warrant Agent, the Company or the holders convening the meeting, as the case may be, may direct in the notice of meeting; and

The form of instrument of proxy; and

The manner in which the form of proxy must be executed; and

Generally for the calling of meeting of warrant holders and the conduct of business thereat.

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 Registered Warrantholder, or be entitled to vote or be present at the meeting in respect thereof (subject to Section 7.9), shall be Registered Warrantholders or proxies of Registered Warrantholders.

In addition to all other powers conferred upon them by any other provisions of this Indenture or by law, the Registered Warrantholders at a meeting shall, subject to the provisions of Section 7.11 and any required approval of the TSX, have the power exercisable from time to time by Extraordinary Resolution:

to agree to any modification, abrogation, alteration, compromise or arrangement of the rights of Registered Warrantholders or the Warrant Agent in its capacity as warrant agent hereunder (subject to the Warrant Agent’s prior consent, acting reasonably) or on behalf of the Registered Warrantholders against the Corporation whether such rights arise under this Indenture or otherwise; provided that, for greater certainty, no rights or obligations of the Corporation under this Indenture or the Warrants will be adversely affected without the Corporation’s consent;

to amend, alter or repeal any Extraordinary Resolution previously passed or sanctioned by the Registered Warrantholders;

to direct or to authorize the Warrant Agent, subject to Section 9.2(2) hereof, to enforce any of the covenants on the part of the Corporation contained in this Indenture or to enforce any of the rights of the Registered Warrantholders in any manner specified in such Extraordinary Resolution or to refrain from enforcing any such covenant or right;

to waive, and to direct the Warrant Agent to waive, any default on the part of the Corporation in complying with any provisions of this Indenture either unconditionally or upon any conditions specified in such Extraordinary Resolution;

to restrain any Registered Warrantholder from taking or instituting any suit, action or proceeding against the Corporation for the enforcement of any of the covenants on the part of the Corporation in this Indenture or to enforce any of the rights of the Registered Warrantholders;

to direct any Registered Warrantholder who, as such, has brought any suit, action or proceeding to stay or to discontinue or otherwise to deal with the same upon payment of the costs, charges and expenses reasonably and properly incurred by such Registered Warrantholder in connection therewith;

to assent to any change in or omission from the provisions contained in this Indenture or any ancillary or supplemental instrument which may be agreed to by the Corporation, and to authorize the Warrant Agent to concur in and execute any ancillary or supplemental indenture embodying the change or omission;

with the consent of the Corporation, such consent not to be unreasonably withheld, to remove the Warrant Agent or its successor in office and to appoint a new warrant agent or warrant agents to take the place of the Warrant Agent so removed; and

to assent to any compromise or arrangement with any creditor or creditors or any class or classes of creditors, whether secured or otherwise, and with holders of any shares or other securities of the Corporation.

The expression “Extraordinary Resolution” when used in this Indenture means, subject as hereinafter provided in this Section 7.11 and in Section 7.14, a resolution proposed at a meeting of Registered 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 Registered Warrantholders holding at least 25% of the aggregate number of Warrants then outstanding and passed by the affirmative votes of Registered Warrantholders holding not less than 66 ^2/3 % of the aggregate number of Warrants then outstanding represented at the meeting and voted on the poll upon such resolution.

If, at the meeting at which an Extraordinary Resolution is to be considered, Registered Warrantholders holding at least 25% of the aggregate number of Warrants then outstanding are not present in person or by proxy within 30 minutes after the time appointed for the meeting, then the meeting, if convened by Registered 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 15 or more than 60 days later, and to such place and time as may be appointed by the chairman. Not less than 14 days’ prior notice shall be given of the time and place of such adjourned meeting in the manner provided for in Section 10.2. Such notice shall state that at the adjourned meeting the Registered Warrantholders present in person or 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 Registered Warrantholders present in person or 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 Section 7.11(1) shall be an Extraordinary Resolution within the meaning of this Indenture notwithstanding that Registered Warrantholders representing at least 25% of the aggregate number of Warrants then outstanding are not present in person or by proxy at such adjourned meeting.

Subject to Section 7.14, 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.

From time to time, the Corporation (when authorized by action of the directors) and the Warrant Agent may, subject to the provisions hereof and they shall, when so directed in accordance with the provisions hereof, 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:

setting forth any adjustments resulting from the application of the provisions of Article 4;

adding to the provisions hereof such additional covenants and enforcement provisions as, in the opinion of Counsel, are necessary or advisable in the premises, provided that the same are not in the opinion of the Warrant Agent, relying on the advice of Counsel, prejudicial to the interests of the Registered Warrantholders;

giving effect to any Extraordinary Resolution passed as provided in Section 7.11;

making such provisions not inconsistent with this Indenture as may be necessary or desirable with respect to matters or questions arising hereunder or for the purpose of obtaining a listing or quotation of the Warrants on any stock exchange, provided that such provisions are not, in the opinion of the Warrant Agent, relying on the advice of Counsel, prejudicial to the interests of the Registered Warrantholders;

adding to or altering the provisions hereof in respect of the transfer of Warrants, making provision for the exchange of Warrants, and making any modification in the form of the Warrant Certificates which does not affect the substance thereof;

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

providing for the issuance of additional Warrants hereunder, including Warrants in excess of the number set out in Section 2.1 and any consequential amendments hereto as may be required by the Warrant Agent relying on the advice of Counsel.

for any other purpose not inconsistent with the terms of this Indenture, including the correction or rectification of any ambiguities, defective or inconsistent provisions, errors, mistakes or omissions herein, provided that in the opinion of the Warrant Agent, relying on the advice of Counsel, the rights of the Warrant Agent and of the Registered Warrantholders are in no way prejudiced thereby.

For greater certainty, approval of the Registered Warrantholders is not required for the purpose of entering into a supplemental indenture pursuant to Section 8.1(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.

The Corporation 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 benefits of Applicable Legislation.

In the exercise of the rights and duties prescribed or conferred by the terms of this Indenture, the Warrant Agent shall exercise that 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 negligent action, wilful misconduct, bad faith or fraud under this Indenture.

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 Registered Warrantholders hereunder shall be conditional upon the Registered Warrantholders furnishing, when required by notice by the Warrant Agent, sufficient funds to commence or to continue such act, action or proceeding and an indemnity reasonably satisfactory to the Warrant Agent to protect and to hold harmless the Warrant Agent and its officers, directors, employees and agents, 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 to risk its own funds or otherwise to 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.

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

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.

In addition to the reports, certificates, opinions and other evidence required by this Indenture, the Corporation 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 Corporation.

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

Whenever it is provided in this Indenture or under Applicable Legislation that the Corporation 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 Corporation to have the Warrant Agent take the action to be based thereon.

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, telegram, cablegram 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 may employ or retain such Counsel, accountants, 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 or negligence on the part of any such experts or advisers who have been appointed with due care by the Warrant Agent.

Proof of execution of any document or instrument in writing; including a Warrantholders’ Request, by a holder may be made by the certificate of a notary public, or other officer 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 the Warrant Agent considers adequate.

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 adviser, whether retained or employed by the Corporation or by the Warrant Agent, in relation to any matter arising in the administration of the agency hereof.

The Warrant Agent may retain any cash balance held in connection with this Warrant Agreement and may, but need not, hold the same in the deposit department of a Canadian chartered bank and its Affiliates; but the Warrant Agent, its Affiliates and a Canadian chartered bank and its Affiliate shall not be liable to account for any profit to the Company or any other person or entity other than at a rate, if any, established from time to time by the Warrant Agent, its Affiliates or a Canadian chartered bank and its Affiliates

The Warrant Agent shall have no responsibility or liability for any diminution of any funds resulting from any investment made in accordance with this Indenture, including any losses on any investment liquidated prior to maturity in order to make a payment required hereunder.

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

the Warrant Agent shall not be liable for or by reason of any statements of fact or recitals in this Indenture or in the Warrant Certificates (except the representation contained in Section 9.9 or in the authentication of the Warrant Agent on the Warrant Certificates) or be required to verify the same, but all such statements or recitals are and shall be deemed to be made by the Corporation;

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;

the Warrant Agent shall not be bound to give notice to any person or persons of the execution hereof;

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 Corporation of any of its covenants herein contained or of any acts of any directors, officers, employees, agents or servants of the Corporation;

the Corporation will fully indemnify and hold the Warrant Agent and its officers, directors, employees and agents harmless from and against any and all actions and suits whether groundless or otherwise and from and against any and all losses, damages, costs, charges, counsel fees, payments, expenses and liabilities arising directly or indirectly out of the performance of its duties and obligations under this Indenture, except for any liability arising out of the Warrant Agent’s gross negligence, fraud or intentional misconduct. In the absence of gross negligence, fraud or intentional misconduct on its part, the Warrant Agent shall not be liable for any action taken, suffered, or omitted by it or for any error of judgement made by it in the performance of its duties under this Indenture. In no event will the Warrant Agent be liable for special, indirect, consequential or punitive loss or damages of any kind whatsoever (including but not limited to lost profits), even if the Warrant Agent has been advised of the possibility of such damages. Any liability of the Warrant Agent will be limited in the aggregate to an amount equal to twelve (12) times the monthly fee paid by the Corporation; and

in the event any question or dispute arises with respect to the Warrant Agent’s duties hereunder, the Warrant Agent shall not be required to act or be held liable or responsible for its failure or refusal to act until the question or dispute has been (i) judicially settled (and, if appropriate the Warrant Agent may file a suit in interpleader or for a declaratory judgement for such purpose) by final judgement by a court of competent jurisdiction that is binding on all parties in the matter and is no longer subject to review or appeal, or (ii) settled by written document in form and substance satisfactory to the Warrant Agent and executed by the Warrant Agent. In addition, the Warrant Agent may require for such purpose, but shall not be obligated to require, the execution of such written settlement by parties that may have an interest in the settlement. It is understood and agreed that this indemnification shall survive the termination or discharge of this Indenture or the resignation or removal of the Warrant Agent.

The Warrant Agent may resign its agency and be discharged from all further duties and liabilities hereunder, subject to this Section 9.8, by giving to the Corporation not less than60 days’ prior notice in writing or such shorter prior notice as the Corporation may accept as sufficient. The Registered Warrantholders by Extraordinary Resolution shall have 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 Corporation shall forthwith appoint a new Warrant Agent unless a new Warrant Agent has already been appointed by the Registered Warrantholders; failing such appointment by the Corporation, the retiring Warrant Agent or any Registered Warrantholder may apply to a judge of the Supreme Court of the Province of British Columbia 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 Corporation or by the Court shall be subject to removal as aforesaid by the Registered Warrantholders. Any new Warrant Agent appointed under any provision of this Section 9.8 shall be an entity authorized to carry on the business of a trust company in the Province of British Columbia and, if required by the Applicable Legislation for any other provinces, in such other provinces. 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 hereunder without further assurance, conveyance, act or deed; but there will be immediately executed, at the expense of the Corporation, all such conveyances or other instruments as may, in the opinion of counsel, be necessary or advisable for the purpose of assuring such powers, rights, duties and responsibilities of the new Warrant Agent, provided that, any resignation or removal of the Warrant Agent and appointment of a successor Warrant Agent shall have executed an appropriate instrument accepting such appointment and, at the request of the Corporation, 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.

Upon the appointment of a successor Warrant Agent, the Corporation shall promptly notify the Registered Warrantholders thereof in the manner provided for in Section 10.2.

Any Warrant Certificates Authenticated but not delivered by a predecessor Warrant Agent may be Authenticated by the successor Warrant Agent in the name of the predecessor or successor Warrant Agent.

Any corporation into which the Warrant Agent may be merged or consolidated or amalgamated, or any corporation resulting therefrom to which the Warrant Agent shall be a party, or any corporation succeeding to substantially the corporate trust business of the Warrant Agent shall be the successor to the Warrant Agent hereunder without any further act on its part or any of the parties hereto, provided that such corporation would be eligible for appointment as successor Warrant Agent under Section 9.8(1).

The Warrant Agent represents to the Corporation that at the time of execution and delivery hereof no material conflict of interest exists between its role as a Warrant Agent hereunder and its role in any other capacity and agrees that in the event of a material conflict of interest arising hereafter it will, within 30 days after ascertaining that it has such material conflict of interest, either eliminate the same or assign its agency hereunder to a successor Warrant Agent approved by the Corporation and meeting the requirements set forth in Section 9.8(1). Notwithstanding the foregoing provisions of this Section 9.9(1), if any such material conflict of interest exists or hereafter shall exist, the validity and enforceability of this Indenture and the Warrant Certificates shall not be affected in any manner whatsoever by reason thereof.

Subject to Section 9.9(1), the Warrant Agent, in its personal or any other capacity, may buy, lend upon and deal in securities of the Corporation and generally may contract and enter into financial transactions with the Corporation without being liable to account for any profit made thereby.

Unless herein otherwise expressly provided, any notice to be given hereunder to the Corporation or the Warrant Agent shall be deemed to be validly given if delivered, sent by registered letter, postage prepaid or if faxed:

and any such notice delivered in accordance with the foregoing shall be deemed to have been received and given on the date of delivery or, if mailed, on the fifth Business Day following the date of mailing such notice or, if faxed, on the next Business Day following the date of transmission.

The Corporation or the Warrant Agent, as the case may be, may from time to time notify the other in the manner provided in Section 10.1(1) of a change of address which, from the effective date of such notice and until changed by like notice, shall be the address of the Corporation or the Warrant Agent, as the case may be, for all purposes of this Indenture.

If, by reason of a strike, lockout or other work stoppage, actual or threatened, involving postal employees, any notice to be given to the Warrant Agent or to the Corporation hereunder could reasonably be considered unlikely to reach its destination, such notice shall be valid and effective only if it is delivered to the named officer of the party to which it is addressed, as provided in Section 10.1(1), or given by facsimile or other means of prepaid, transmitted and recorded communication.

Unless otherwise provided herein, notice to the Registered Warrantholders under the provisions of this Indenture shall be valid and effective if delivered or sent by ordinary prepaid post addressed to such holders at their post office addresses appearing on the register hereinbefore mentioned and shall be deemed to have been effectively received and given on the date following the date of delivery or, if mailed, on the fifth Business Day following the date of mailing such notice. Accidental error or omission in giving notice or accidental failure to mail notice to any holder will not invalidate any action or proceeding founded thereon. In the event that Warrants are held in the name of the Depository, a copy of such notice shall also be sent by electronic communication to the Depository and shall be deemed received and given on the day it is so sent.

If, by reason of a strike, lockout or other work stoppage, actual or threatened, involving postal employees, any notice to be given to the Registered Warrantholders hereunder could reasonably be considered unlikely to reach its destination, such notice shall be valid and effective only if it is delivered to such Registered Warrantholders to the address for such Registered Warrantholders contained in the register maintained by the Warrant
