- 15 -

Section 2.5 Form and Terms of Initial Debentures

(1) The first series of Debentures (the “Initial Debentures”) authorized for issue immediately is limited to an aggregate principal amount of up to $115,000,000 and shall be designated as “6.0% Unsecured Convertible Debentures”.

(2) The Initial Debentures shall be dated as of the Deemed Exercise Date and shall mature on November 28, 2022 (the “Maturity Date” for the Initial Debentures).

(3) The Initial Debentures shall bear interest from the date of closing of the Offering at the rate of 6.0% per annum (based on a year of 360 days comprised of twelve 30-day months), payable in equal (with the exception of the first interest payment, which will include interest from and including the date of closing of the Offering as set forth below, and, if the Initial Debentures are issued at any time following December 31, 2017, the second interest payment, which will include interest from the date following issuance of the Initial Debentures to the next interest payment date) semi-annual payments in arrears on June 30 and December 31 in each year, the first such payment to fall due on December 31, 2017 and the last such payment (representing interest payable from the last Interest Payment Date to, but excluding, the Maturity Date of the Initial Debentures) to fall due on November 28, 2022, payable after as well as before maturity and after as well as before default, with interest on amounts in default at the same rate, compounded semi-annually. For certainty, in the event that the Initial Debentures are issued (i) on or before December 31, 2017, the first interest payment will include interest accrued from November 28, 2017 to December 31, 2017, which will be equal to $5.50 for each $1,000 principal amount of Initial Debentures; or (ii) at any time following December 31, 2017, the first interest payment will include interest accrued from November 28, 2017 to the date that the Initial Debentures are so issued and, notwithstanding anything to the contrary contained herein, shall be payable on the Business Day immediately following the date of issuance. Any payment required to be made on any day that is not a Business Day will be made on the next succeeding Business Day. The record date for the payment of interest on the Initial Debentures will be that date which is five Business Days prior to each Interest Payment Date.

(4) The Initial Debentures will be subordinated to all existing and future Secured Indebtedness of the Corporation in accordance with the provisions of Article 5. The Initial Debentures will rank pari passu with each other series of Debentures issued under this Indenture or under indentures supplemental to this Indenture (regardless of their actual date or terms of issue) and, except as prescribed by law, with all other existing and future unsecured indebtedness of the Corporation, other than Secured Indebtedness.

- 16 -

(5) Upon and subject to the provisions and conditions of Article 6 and Section 3.7, the holder of each Initial Debenture shall have the right at such holder’s option, at any time prior to the close of business on the earliest of (i) the Business Day immediately preceding the Maturity Date of the Initial Debentures; or (ii) if subject to repurchase pursuant to a Change of Control, on the Business Day immediately preceding the payment date, subject to the satisfaction of certain conditions, by notice to the holders of Initial Debentures in accordance with Section 2.5(7) (the earlier of which will be the “Time of Expiry” for the purposes of Article 6 in respect of the Initial Debentures), to convert any part, being $1,000 or an integral multiple thereof, of the principal amount of a Debenture into Common Shares at the Conversion Price in effect on the Date of Conversion. Notwithstanding the foregoing, no Initial Debentures may be converted on an Interest Payment Date or during the five Business Days preceding each Interest Payment Date.

The Conversion Price in effect on the date hereof for each Common Share to be issued upon the conversion of Initial Debentures shall be equal to $6.50 such that approximately 153.8462 Common Shares shall be issued for each $1,000 principal amount of Initial Debentures so converted. Except as provided below, no adjustment in the number of Common Shares to be issued upon conversion will be made for dividends or distributions on Common Shares issuable upon conversion, the record date for the payment of which precedes the date upon which the holder becomes a holder of Common Shares in accordance with Article 6, or for interest accrued on Initial Debentures surrendered. No fractional Common Shares will be issued, and holders will receive a cash payment in satisfaction of any fractional interest based on the Current Market Price as of the Date of Conversion, provided, however, the Corporation shall not be required to make any payment of less than $1.00. The Conversion Price applicable to, and the Common Shares, securities or other property receivable on the conversion of, the Initial Debentures is subject to adjustment pursuant to the provisions of Section 6.5. Holders converting their Initial Debentures will receive, in addition to the applicable number of Common Shares, accrued and unpaid interest (less any taxes required to be deducted) in respect of the Initial Debentures surrendered for conversion up to but excluding the Date of Conversion from, and including, the most recent Interest Payment Date. For clarity, payment of such interest may, at the option of the Corporation, be paid on the next regularly scheduled Interest Payment Date following the Date of Conversion.

The Conversion Price will not be adjusted for accrued interest.

Notwithstanding any other provisions of this Indenture, if a Debenture is surrendered for conversion on an Interest Payment Date or during the five preceding Business Days, the Person or Persons entitled to receive Common Shares in respect of the Debenture so surrendered for conversion shall not become the holder or holders of record of such Common Shares until the Business Day following such Interest Payment Date and, for clarity, any interest payable on such Debentures will be for the account of the holder of record of such Debentures at the close of business on the relevant record date.

- 17 -

A Debenture in respect of which a holder has accepted a notice in respect of a Change of Control Offer pursuant to the provisions of subsection 2.5(7) may be surrendered for conversion only if such notice is withdrawn in accordance with this Indenture.

(6) The Initial Debentures shall be issued in denominations of $1,000 and integral multiples of $1,000. Each Initial Debenture and the certificate of the Trustee endorsed thereon shall be issued in substantially the form set out in Schedule A, with such insertions, omissions, substitutions or other variations as shall be required or permitted by this Indenture, and may have imprinted or otherwise reproduced thereon such legend or legends or endorsements, not inconsistent with the provisions of this Indenture, as may be required to comply with any law or with any rules or regulations pursuant thereto or with any rules or regulations of any securities exchange or securities regulatory authority or to conform with general usage, all as may be determined by the Board of Directors executing such Initial Debenture in accordance with Section 2.8 hereof, as conclusively evidenced by their execution of an Initial Debenture. Each Initial Debenture shall additionally bear such distinguishing letters and numbers as the Trustee shall approve. Notwithstanding the foregoing, an Initial Debenture may be in such other form or forms as may, from time to time, be, approved by a resolution of the Board of Directors, or as specified in an Officer’s Certificate. The Initial Debentures may be engraved, lithographed, printed, mimeographed or typewritten or partly in one form and partly in another.

The Initial Debentures shall be issued in the form of one or more Debenture Certificates, shall bear the U.S. Legend, if applicable, and as Uncertificated Debentures.

(7) Within 30 days following a Change of Control, and subject to the provisions and conditions of this subsection 2.5(7), the Corporation shall, at the discretion of the Debentureholders, be obligated to offer to purchase or convert all of the Initial Debentures then outstanding. The terms and conditions of such obligation are set forth below:

	(a)	Not less than 30 days following the occurrence of a Change of Control, the Corporation shall deliver to the Trustee, and the Trustee shall promptly deliver to the holders of the Initial Debentures, a notice stating that there has been a Change of Control and specifying the date on which such Change of Control occurred and the circumstances or events giving rise to such Change of Control (a “Change of Control Notice”). Prior to the Change of Control Purchase Date (as defined below), the Debentureholders shall, in their sole discretion, have the right to require the Corporation to, either: (i) purchase the Debentures at 104% of the principal amount thereof plus unpaid interest to the Maturity Date (the “Offer Price”); or (ii) convert the Debentures at the Conversion Price (the “Change of Control Offer”). The “Change of Control Purchase Date” shall be the date that is 30 Business Days after the date of the Change of Control Notice is delivered to holders of Initial Debentures.

	(b)	If 90% or more in aggregate principal amount of Initial Debentures outstanding on the date the Corporation provides the Change of Control Notice to holders of the Initial Debentures have been surrendered for purchase pursuant to the Change of Control Offer on the expiration thereof, the Corporation has the right upon written notice provided to the Trustee within 10 days following the expiration of the Change of Control Offer, to redeem all the Initial Debentures remaining outstanding on the expiration of the Change of Control Offer at the Offer Price as at the Change of Control Purchase Date (the “90% Redemption Right”).

- 18 -

(c)

Upon receipt of notice that the Corporation has exercised or is exercising the 90% Redemption Right and is acquiring the remaining Initial Debentures, the Trustee shall promptly provide written notice to each Debentureholder that did not previously accept the Change of Control Offer that:

	(i)	the Corporation has exercised the 90% Redemption Right and is purchasing all outstanding Initial Debentures effective on the expiry of the Change of Control Offer at the Offer Price, and shall include a calculation of the amount payable to such holder as payment of the Offer Price as at the Change of Control Purchase Date;

	(ii)	each such holder must transfer their Initial Debentures to the Trustee on the same terms as those holders that accepted the Change of Control Offer and must send their respective Initial Debentures, duly endorsed for transfer, to the Trustee within 10 days after the sending of such notice; and

	(iii)	the rights of such holder under the terms of the Initial Debentures and this Indenture cease effective as of the date of expiry of the Change of Control Offer provided the Corporation has, on or before the time of notifying the Trustee of the exercise of the 90% Redemption Right, paid the Offer Price to, or to the order of, the Trustee and thereafter the Initial Debentures shall not be considered to be outstanding and the holder shall not have any right except to receive such holder’s Offer Price upon surrender and delivery of such holder’s Initial Debentures in accordance with the Indenture.

(d)

The Corporation shall, on or before 11:00 a.m. (Vancouver time) on the Business Day immediately prior to the Change of Control Purchase Date, deposit with the Trustee or any paying agent to the order of the Trustee, such sums of money as may be sufficient to pay the Offer Price of the Initial Debentures to be purchased or redeemed by the Corporation on the Change of Control Purchase Date (less any tax required by law to be deducted in respect of accrued and unpaid interest), provided the Corporation may elect to satisfy this requirement by providing the Trustee with a certified cheque or wire transfer for such amounts required under this clause 2.5(7)(d) post-dated to the date of expiry of the Change of Control Offer. The Corporation shall also deposit with the Trustee a sum of money sufficient to pay any charges or expenses which may be incurred by the Trustee in connection with such purchase. Every such deposit shall be irrevocable. From the sums so deposited, the Trustee shall pay or cause to be paid to the holders of such Initial Debentures, the Offer Price to which they are entitled (less any tax required by law to be deducted in respect of accrued and unpaid interest) on the Corporation’s purchase.

- 19 -

	(e)	In the event that one or more of such Initial Debentures being purchased in accordance with this subsection 2.5(7) becomes subject to purchase in part only, upon surrender of such Initial Debentures for payment of the Offer Price, the Corporation shall execute and the Trustee shall certify and deliver without charge to the holder thereof or upon the holder’s order, one or more new Initial Debentures for the portion of the principal amount of the Initial Debentures not purchased.

	(f)	Initial Debentures for which holders have accepted the Change of Control Offer and Initial Debentures which the Corporation has elected to redeem in accordance with this subsection 2.5(7) shall become due and payable at the Offer Price on the Change of Control Purchase Date, in the same manner and with the same effect as if it were the date of maturity specified in such Initial Debentures, anything therein or herein to the contrary notwithstanding, and from and after the Change of Control Purchase Date, if the money necessary to purchase or redeem, or the Common Shares necessary to purchase or redeem, the Initial Debentures shall have been deposited as provided in this subsection 2.5(7) and affidavits or other proofs satisfactory to the Trustee as to the publication and/or mailing of such notices shall have been lodged with it, interest on the Initial Debentures shall cease. If any question shall arise as to whether any notice has been given as above provided and such deposit made, such question shall be decided by the Trustee whose decision shall be final and binding upon all parties in interest.

	(g)	In case the holder of any Initial Debenture to be purchased or redeemed in accordance with this subsection 2.5(7) shall fail on or before the Change of Control Purchase Date to so surrender such holder’s Initial Debenture or shall not within such time accept payment of the monies payable, to take delivery of certificates representing such Common Shares issuable in respect thereof, or give such receipt therefor, if any, as the Trustee may require, such monies may be set aside in trust, or such certificates may be held in trust, without interest, either in the deposit department of the Trustee or in a chartered bank, and such setting aside shall for all purposes be deemed a payment to the Debentureholder of the sum or the Common Shares so set aside and the Debentureholder shall have no other right except to receive payment of the monies so paid and deposited, or take delivery of the certificates so deposited, or both, upon surrender and delivery of such holder’s Initial Debenture. In the event that any money or certificates representing Common Shares required to be deposited hereunder with the Trustee or any depository or paying agent on account of principal, premium, if any, or interest, if any, on Initial Debentures issued hereunder shall remain so deposited for a period of six years from the Change of Control Purchase Date, then such monies, or certificates representing Common Shares, together with any accumulated interest thereon, or any distributions paid thereon, shall at the end of such period be paid over or delivered over by the Trustee or such depository or paying agent to the Corporation and the Trustee shall not be responsible to Debentureholders for any amounts owing to them. Notwithstanding the foregoing, the Trustee will pay any remaining funds deposited hereunder on that date which is six years after the Change of Control Purchase Date (the “Unclaimed Funds Return Date”) to the Corporation upon receipt from the Corporation of an unconditional letter of credit from a Canadian chartered bank in an amount equal to or in excess of the amount of the remaining funds. If the remaining funds are paid to the Corporation prior to the Unclaimed Funds Return Date, the Corporation shall reimburse the Trustee for any amounts required to be paid by the Trustee to a holder of a Debenture pursuant to the Change of Control Offer after the date of such payment of the remaining funds to the Corporation but prior to the Unclaimed Funds Return Date.

- 20 -

(h)

Subject to the provisions above related to Initial Debentures purchased in part, all Initial Debentures redeemed and paid under this subsection 2.5(7) shall forthwith be delivered to the Trustee and cancelled and no Initial Debentures shall be issued in substitution therefor.

	(ii)	the Trustee shall certify and deliver Additional Debentures of such series for original issue from time to time, in an aggregate principal amount not exceeding the aggregate principal amount, if any, established for such series, pursuant to a Written Direction of the Corporation or pursuant to procedures acceptable to the Trustee as may be specified from time to time by a Written Direction of the Corporation;

(1) Subject to the provisions hereof, at the Corporation’s option, Debentures may be issued and registered in the name of CDS or its nominee and:

(2) If the Corporation issues Debentures in a non-certificated format, Beneficial Holders of such Debentures registered and deposited with CDS shall not receive Debenture Certificates in definitive form and shall not be considered owners or holders thereof under this Indenture or any supplemental indenture. Beneficial interests in Debentures registered and deposited with CDS will be represented only through the non-certificated inventory system administered by CDS.

Transfers of Debentures registered and deposited with CDS between Participants shall occur in accordance with the rules and procedures of CDS. Neither the Corporation nor the Trustee shall have any responsibility or liability for any aspects of the records relating to or payments made by CDS or its nominee, on account of the beneficial interests in Debentures registered and deposited with CDS. Nothing herein shall prevent the Beneficial Holders of Debentures registered and deposited with CDS from voting such Debentures using duly executed proxies or voting instruction forms.

(3) All references herein to actions by, notices given or payments made to Debentures shall, where Debentures are held through CDS, refer to actions taken by, or notices given or payments made to, CDS upon instruction from the Participants in accordance with its rules and procedures. For the purposes of any provision hereof requiring or permitting actions with the consent of or the direction of Debentureholders evidencing a specified percentage of the aggregate Debentures outstanding, such direction or consent may be given by Beneficial Holders acting through CDS and the Participants owning Debentures evidencing the requisite percentage of the Debentures. The rights of a Beneficial Holder whose Debentures are held established by law and agreements between such holders and CDS and the Participants upon instructions from the Participants. Each Trustee and the Corporation may deal with CDS for all purposes (including the making of payments) as the authorized representative of the respective Debentures and such dealing with CDS shall constitute satisfaction or performance, as applicable, of their respective obligations hereunder.

(4) For so long as Debentures are held through CDS, if any notice or other communication is required to be given to Debentureholders, the Trustee will give such notices and communications to CDS.

(5) If CDS resigns or is removed from its responsibility as Depository and the Trustee is unable or does not wish to locate a qualified successor, CDS shall provide the Trustee with instructions for registration of Debentures in the names and in the amounts specified by CDS and the Corporation shall issue and the Trustee shall certify and deliver the aggregate number of Debentures then outstanding in the form of definitive Debentures Certificates representing such Debentures.

(6) The rights of Beneficial Holders who hold securities entitlements in respect of the Debentures through non-certificated inventory system administered by CDS shall be limited to those established by applicable law and agreements between the Depository and the Participants and between such Participants and the Beneficial Holders who hold securities entitlements in respect of the Debentures through the non-certificated inventory system administered by CDS, and such rights must be exercised through a Participant in accordance with the rules and procedures of the Depository.

(7) Notwithstanding anything herein to the contrary, none of the Corporation nor the Trustee 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 other interests in the Debentures 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 Debenture represented by an electronic position in the non-certificated inventory system administered by CDS (other than Depository or its nominee);

- 23 -

	(b)	for maintaining, supervising or reviewing any records of the Depository or any 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 Participant.

(8) The Corporation may terminate the application of this Section 2.7 in its sole discretion in which case all Debentures shall be evidenced by Debenture Certificates registered in the name of a Person other than the Depository.

Section 2.8 Execution of Debentures

All Debentures shall be signed (either manually or by facsimile or other electronic signature) by any one authorized director or officer of the Corporation holding office at the time of signing. A facsimile or electronic signature upon a Debenture shall for all purposes of this Indenture be deemed to be the signature of the Person whose signature it purports to be. Notwithstanding that any Person whose signature, either manual or in facsimile or electronic form, appears on a Debenture as a director or officer may no longer hold such office at the date of the Debenture or at the date of the certification and delivery thereof, such Debenture shall be valid and binding upon the Corporation and entitled to the benefits of this Indenture.

Section 2.9 Certification

(1) No Debenture shall be issued or, if issued, shall be obligatory or shall entitle the holder to the benefits of this Indenture, until it has been certified by or on behalf of the Trustee substantially in the form set out in this Indenture, in the relevant supplemental indenture, or in some other form approved by the Trustee. Such certification or authentication of any Debenture shall be conclusive evidence that such Debenture is duly issued, is a valid obligation of the Corporation and the holder is entitled to the benefits hereof. Debentures will be authenticated on a Written Direction of the Corporation.

(2) The certificate of the Trustee signed on the Debentures, or interim Debentures hereinafter mentioned, and the authentication of Uncertificated Debentures, shall not be construed as a representation or warranty by the Trustee as to the validity of this Indenture or of the Debentures or interim Debentures or as to the issuance of the Debentures or interim Debentures and the Trustee shall in no respect be liable or answerable for the use made of the Debentures or interim Debentures or any of them or the proceeds thereof. The certificate of the Trustee on the Debentures or interim Debentures, and the authentication of Uncertificated Debentures, shall, however, be a representation and warranty by the Trustee that the Debentures or interim Debentures have been duly certified by or on behalf of the Trustee pursuant to the provisions of this Indenture.

- 24 -

(3) The Trustee shall certify Uncertificated Debentures (whether upon original issuance, exchange, registration of transfer 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 Debentures have 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 Debentures with respect to which this Indenture requires the Trustee 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 Debentures are binding on the Corporation.

Section 2.10 Interim Debentures or Certificates

Pending the delivery of definitive Debentures of any series to the Trustee, the Corporation may issue and the Trustee certify in lieu thereof interim Debentures in such forms and in such denominations and signed in such manner as provided herein, entitling the holders thereof to definitive Debentures of the series when the same are ready for delivery; or the Corporation may execute and the Trustee certify a temporary Debenture for the whole principal amount of Debentures of the series then authorized to be issued hereunder and deliver the same to the Trustee and thereupon the Trustee may issue its own interim certificates in such form and in such amounts, not exceeding in the aggregate the principal amount of the temporary Debenture so delivered to it, as the Corporation and the Trustee may approve entitling the holders thereof to definitive Debentures of the series when the same are ready for delivery; and, when so issued and certified, such interim or temporary Debentures or interim certificates shall, for all purposes but without duplication, rank in respect of this Indenture equally with Debentures duly issued hereunder and, pending the exchange thereof for definitive Debentures, the holders of the interim or temporary Debentures or interim certificates shall be deemed without duplication to be Debentureholders and entitled to the benefit of this Indenture to the same extent and in the same manner as though the said exchange had actually been made. Forthwith after the Corporation shall have delivered the definitive Debentures to the Trustee, the Trustee shall cancel such temporary Debentures, if any, and shall call in for exchange all interim Debentures or certificates that shall have been issued and forthwith after such exchange shall cancel the same. No charge shall be made by the Corporation or the Trustee to the holders of such interim or temporary Debentures or interim certificates for the exchange thereof. All interest paid upon interim or temporary Debentures or interim certificates shall be noted thereon as a condition precedent to such payment unless paid by cheque to the registered holders thereof.

Section 2.11 Mutilation, Loss, Theft or Destruction

In case any of the Debentures issued hereunder shall become mutilated or be lost, stolen or destroyed, the Corporation, in its discretion, may issue, and thereupon the Trustee shall certify and deliver, a new Debenture upon surrender and cancellation of the mutilated Debenture, or in the case of a lost, stolen or destroyed Debenture, in lieu of and in substitution for the same, and the substituted Debenture shall be in a form approved by the Trustee and shall be entitled to the benefits of this Indenture and rank equally in accordance with its terms with all other Debentures issued or to be issued hereunder. In case of loss, theft or destruction the applicant for a substituted Debenture shall furnish to the Corporation and to the Trustee such evidence of the loss, theft or destruction of the Debenture as shall be satisfactory to them in their discretion and shall also furnish an indemnity and surety bond satisfactory to them in their discretion. The applicant shall pay all reasonable expenses incidental to the issuance of any substituted Debenture.

- 25 -

Section 2.12 Concerning Interest

(1) All Debentures issued hereunder, whether originally or upon exchange or in substitution for previously issued Debentures which are interest bearing, shall bear interest (i) from and including their issue date, or (ii) from and including the last Interest Payment Date to which interest shall have been paid or made available for payment on the outstanding Debentures of that series, whichever shall be the later, or, in respect of Debentures subject to a Periodic Offering, from and including their issue date or from and including the last Interest Payment Date to which interest shall have been paid or made available for payment on such Debentures, in all cases, to and excluding the next Interest Payment Date.

(2) Unless otherwise specifically provided in the terms of the Debentures of any series, interest shall be computed on the basis of a year of 360 days comprised of twelve 30-day months. With respect to any series of Debentures, whenever interest is computed on the basis of a year (the “deemed year”) which contains fewer days than the actual number of days in the calendar year of calculation, such rate of interest shall be expressed as a yearly rate for purposes of the Interest Act (Canada) by multiplying such rate of interest by the actual number of days in the calendar year of calculation and dividing it by the number of days in the deemed year.

Section 2.13 Debentures to Rank Pari Passu

The Debentures will be direct unsecured obligations of the Corporation. Each Debenture of the same series of Debentures will rank pari passu with each other Debenture of the same series (regardless of their actual date or terms of issue) and, subject to statutory preferred exceptions, with all other present and future unsecured indebtedness of the Corporation.

Section 2.14 Payments of Amounts Due on Maturity

Except as may otherwise be provided herein or in any supplemental indenture in respect of any series of Debentures, payments of amounts due upon maturity of the Debentures will be made in the following manner. The Corporation will establish and maintain with the Trustee a Maturity Account for each series of Debentures. Each such Maturity Account shall be maintained by and be subject to the control of the Trustee for the purposes of this Indenture. On or before 11:00 a.m. (Vancouver time) on the Business Day immediately prior to each Maturity Date for Debentures outstanding from time to time under this Indenture, the Corporation will deliver to the Trustee a certified cheque or wire transfer for deposit in the applicable Maturity Account in an amount sufficient to pay the cash amount payable in respect of such Debentures (including the principal amount together with any accrued and unpaid interest thereon less any tax required by law to be deducted), provided the Corporation may elect to satisfy this requirement by providing the Trustee with a cheque for such amounts required under this Section 2.14 post-dated to the applicable Maturity Date. The Trustee, on behalf of the Corporation, will pay to each holder entitled to receive payment the principal amount of and premium (if any) and accrued and unpaid interest on the Debenture, upon surrender of the Debenture at any branch of the Trustee designated for such purpose from time to time by the Corporation and the Trustee. The delivery of such funds to the Trustee for deposit to the applicable Maturity Account will satisfy and discharge the liability of the Corporation for the Debentures to which the delivery of funds relates to the extent of the amount delivered (plus the amount of any tax deducted as aforesaid) and such Debentures will thereafter to that extent not be considered as outstanding under this Indenture and such holder will have no other right in regard thereto other than to receive out of the money so delivered or made available the amount to which it is entitled.

- 26 -

Section 2.15 U.S. Legend

(1) The Debentures and Common Shares issuable upon conversion thereof have not been and will not be registered under the 1933 Act or any state securities laws. To the extent that Initial Debentures are offered and sold in the United States to Qualified Institutional Buyers in reliance on an exemption from registration under Rule 144A under the 1933 Act, such Initial Debentures and all Common Shares issuable on conversion thereof (collectively, the “Securities”), shall be “restricted securities” within the meaning assigned to that term in Rule 144(a)(3) under the 1933 Act. Subject to subsection 2.15(3), such Securities, as well as all securities issued in exchange for or in substitution of the Securities, shall be issued in certificated form bearing the legend below or under a separate, restricted CUSIP number and, until such time as the same is no longer required under applicable requirements of the 1933 Act or state securities laws, shall bear the following legend (the “US Legend”):

(a)

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN AND WILL NOT BE REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “U.S. SECURITIES ACT”) OR THE LAWS OF ANY STATE OF THE UNITED STATES. THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT OF AURORA CANNABIS INC. (THE “CORPORATION”), THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED, DIRECTLY OR INDIRECTLY, ONLY (A) TO THE CORPORATION, (B) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT AND (C) IN COMPLIANCE WITH APPLICABLE LOCAL LAWS AND REGULATIONS, IN COMPLIANCE WITH THE EXEMPTION FROM REGISTRATION UNDER THE U.S. SECURITIES ACT PROVIDED BY (i) RULE 144 THEREUNDER, IF AVAILABLE, OR (ii) RULE 144A THEREUNDER, IF AVAILABLE, AND, IN BOTH CASES, IN ACCORDANCE WITH APPLICABLE U.S. STATE SECURITIES LAWS, OR (D) IN A TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT OR ANY APPLICABLE U.S. STATE SECURITIES LAWS, AND, IN THE CASE OF (C)(i) OR (D) ABOVE, AFTER THE SELLER FURNISHES TO THE CORPORATION AN OPINION OF COUNSEL OF RECOGNIZED STANDING IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE CORPORATION AND THE [TRANSFER AGENT][TRUSTEE] TO SUCH EFFECT. DELIVERY OF THIS CERTIFICATE MAY NOT CONSTITUTE “GOOD DELIVERY” IN SETTLEMENT OF TRANSACTIONS ON STOCK EXCHANGES IN CANADA.”

- 27 -

provided that if the Debentures or Common Shares are being sold in compliance with the requirements of Rule 904 of Regulation S and in compliance with Canadian local laws and regulations, and provided that the Corporation is a “foreign issuer” within the meaning of Regulation S at the time of issuance of the Debentures or Common Shares, as applicable, such Securities may be transferred to an unrestricted CUSIP or the U.S. Legend may be removed by providing a declaration to the Trustee substantially as set forth in Schedule D (or as the Corporation or the Trustee may prescribe from time to time), together with any other evidence reasonably requested by the Corporation or Trustee, which evidence may include an opinion of counsel of recognized standing, in form and substance reasonably satisfactory to the Corporation and the Trustee, to the effect that the transfer is being made in compliance with Rule 904 of Regulation S; and provided further that, if any Debentures or Common Shares are being sold in accordance with Rule 144 under the 1933 Act, if available, the Debentures or Common Shares, as applicable, may be transferred into an unrestricted CUSIP or the U.S. Legend may be removed by delivery to the Trustee of an opinion of counsel of recognized standing, in form and substance reasonably satisfactory to the Trustee and the Corporation, that the Debentures or Common Shares no longer required a restricted CUSIP or the U.S. Legend is no longer required under applicable requirements of the 1933 Act or applicable state securities laws. Provided that the Trustee obtains confirmation from the Corporation that such counsel is satisfactory to it, it shall be entitled to rely on such opinion of counsel without further inquiry.

(2) The parties hereto hereby acknowledge and agree that the Securities may not be reoffered, or resold, pledged or otherwise transferred except: (i) to the Corporation; (ii) outside the United States in accordance with Regulation S and in compliance with applicable local laws and regulations; (iii) in compliance with the exemption from registration under the 1933 Act provided by (A) Rule 144 under the 1933 Act, or (B) Rule 144A under the 1933 Act, if applicable, and, in each case, in accordance with applicable state securities laws; or (iv) in a transaction that does not require registration under the 1933 Act or any applicable state securities laws.

- 28 -

(3) Notwithstanding subsection 2.15(1), to the extent that a Qualified Institutional Buyer acquiring the Initial Debentures pursuant to the Offering has duly executed and delivered a U.S. Purchaser Letter substantially as set forth in Schedule F, such Initial Debentures shall be included in the Unrestricted Debentures, and any Common Shares issued to such Qualified Institutional Buyer upon conversion of such Initial Debentures shall neither be required to be issued under a restricted CUSIP nor bear a U.S. Legend.

(4) Prior to the issuance of the Debentures, the Corporation shall notify the Trustee, in writing, concerning which Debentures are to be included in the Restricted Debentures which shall bear the U.S. Legend. All Securities issued pursuant to Rule 144A under the 1933 Act shall bear the U.S. Legend. The Trustee will thereafter maintain a list of all registered holders from time to time of such legended Debentures.

Section 2.16 Payment of Interest

The following provisions shall apply to Debentures, except as otherwise provided in subsection 2.5(3) or specified in a resolution of the Board of Directors, an Officer’s Certificate or a supplemental indenture relating to a particular series of Additional Debentures:

(a)

As interest becomes due on each Debenture (except, subject to certain exceptions set forth herein including in subsection 2.5(3), on conversion or on redemption, when interest may at the option of the Corporation be paid upon surrender of such Debenture), the Corporation, either directly or through the Trustee or any agent of the Trustee, shall send or forward by prepaid ordinary mail, wire transfer of funds or such other means as may be agreed to by the Trustee, payment of such interest (less any tax required to be withheld therefrom) to the order of the registered holder of such Debenture appearing on the registers maintained by the Trustee at the close of business on the record date prior to the applicable Interest Payment Date and addressed to the holder at the holder’s last address appearing on the register, unless such holder otherwise directs. If payment is made by cheque, such cheque shall be forwarded at least three days prior to each date on which interest becomes due and if payment is made by other means (such as electronic transfer of funds, provided the Trustee must receive confirmation of receipt of funds prior to being able to wire funds to holders), such payment shall be made in a manner whereby the holder receives credit for such payment on the date such interest on such Debenture becomes due. The mailing of such cheque or the making of such payment by other means shall, to the extent of the sum represented thereby, plus the amount of any tax withheld as aforesaid, satisfy and discharge all liability for interest on such Debenture, unless in the case of payment by cheque, such cheque is not paid at par on presentation. In the event of non-receipt of any cheque for or other payment of interest by the Person to whom it is so sent as aforesaid, the Corporation will issue to such Person a replacement cheque or other payment for a like amount upon being furnished with such evidence of non-receipt as it shall reasonably require and upon being indemnified to its satisfaction. Notwithstanding the foregoing, if the Corporation is prevented by circumstances beyond its control (including, without limitation, any interruption in mail service) from making payment of any interest due on each Debenture in the manner provided above, the Corporation may make payment of such interest or make such interest available for payment in any other manner acceptable to the Trustee with the same effect as though payment had been made in the manner provided above.

- 29 -

(b)

All payments of interest on the Uncertificated Debenture shall be made by wire funds transfer or certified cheque made payable (i) to the Depository or its nominee on the day interest is payable for subsequent payment to Beneficial Holders of the applicable Uncertificated Debenture, unless the Corporation and the Depository otherwise agree or (ii) if the Corporation wishes to have the Trustee act as interest paying agent, to the Trustee by no later than the Business Day prior to the day interest is payable for subsequent payment to Beneficial Holders of the applicable Uncertificated Debenture. None of the Corporation, the Trustee or any agent of the Trustee for any Debenture issued as an Uncertificated Debenture will be liable or responsible to any Person for any aspect of the records related to or payments made on account of beneficial interests in any Uncertificated Debenture or for maintaining, reviewing, or supervising any records relating to such beneficial interests.

ARTICLE 3– REGISTRATION, TRANSFER, EXCHANGE AND OWNERSHIP

Section 3.1 Global Debentures or Book Based Only Debentures

(1) With respect to each series of Debentures issuable in whole or in part as one or more Global Debentures and/or as Book Based Only Debentures, the Corporation shall cause to be kept by and at the principal offices of the Trustee in Vancouver, British Columbia and by the Trustee or such other registrar as the Corporation, with the approval of the Trustee, may appoint at such other place or places, if any, as the Corporation may designate with the approval of the Trustee, a register in which shall be entered the name and address of the holder of each such Global Debenture and/or Book Based Only Debenture as holder thereof and particulars of the Global Debenture and/or Book Based Only Debenture held by it, and of all transfers thereof. If any Debentures of such series are at any time not Global Debentures or Book Based Only Debentures, the provisions of Section Error! Reference source not found. shall govern with respect to registrations and transfers of such Debentures.

(2) Notwithstanding any other provision of this Indenture, a Global Debenture or Book Based Only Debenture may not be transferred by the registered holder thereof and accordingly, no definitive certificates shall be issued to Beneficial Holders except in the following circumstances or as otherwise specified in a resolution of the Directors, an Officer’s Certificate or a supplemental indenture relating to a particular series of Additional Debentures:

(a)

Global Debentures or Book Based Only Debentures may be transferred by a Depository to a nominee of such Depository or by a nominee of a Depository to such Depository or to another nominee of such Depository or by a Depository or its nominee to a successor Depository or its nominee;

- 30 -

	(b)	Global Debentures or Book Based Only Debentures may be transferred at any time after (i) the Depository for such Global Debentures or Book Based Only Debentures, as the case may be, or the Corporation has notified the Trustee that the Depository is unwilling or unable to continue as Depository for such Global Debentures or Book Based Only Debentures, or (ii) the Depository ceases to be a clearing agency or otherwise ceases to be eligible to be a Depository under Section Section 2.1(2), provided in each case that at the time of such transfer the Trustee and the Corporation are unable to locate a qualified successor Depository for such Global Debentures or Book Based Only Debentures;

	(c)	Global Debentures or Book Based Only Debentures may be transferred at any time after the Corporation has determined, in its sole discretion, with the consent of the Trustee to terminate the book-entry only registration system or book based entry, as the case may be, in respect of such Global Debentures or Book Based Only Debentures and has communicated such determination to the Trustee in writing;

	(d)	Global Debentures or Book Based Only Debentures may be transferred at any time after the Trustee has determined that an Event of Default has occurred and is continuing with respect to the Debentures of the series issued as a Global Debenture or Book Based Only Debentures, as the case may be, provided that Beneficial Holders of the Debentures representing, in the aggregate, more than 25% of the aggregate principal amount of the Debentures of such series advise the Depository in writing, through the Depository Participants, that the continuation of the book-entry only registration system or book based entry, as applicable, for such series of Debentures is no longer in their best interest and also provided that at the time of such transfer the Trustee has not waived the Event of Default pursuant to Section Error! Reference source not found.;

	(e)	Global Debentures or Book Based Only Debentures may be transferred if required by applicable law; or

	(f)	Global Debentures or Book Based Only Debentures may be transferred if the book-entry only registration system or book based entry, as applicable, ceases to exist.

(3) With respect to the Global Debentures, unless and until definitive certificates have been issued to Beneficial Holders of the Debentures pursuant to subsection Section 3.1(2):

(a)

the Corporation and the Trustee may deal with the Depository for all purposes (including paying interest on the Debentures) as the sole holder of such series of Debentures and the authorized representative of the Beneficial Holders;

- 31 -

	(b)	the rights of the Beneficial Holders of the Debentures shall be exercised only through the Depository and shall be limited to those established by law and agreements between such Beneficial Holders and the Depository or the Depository Participants;

	(c)	the Depository will make book-entry or book based, as applicable, transfers among the Depository Participants; and

	(d)	whenever this Indenture requires or permits actions to be taken based upon instructions or directions of Debentureholders evidencing a specified percentage of the outstanding Debentures, the Depository shall be deemed to be counted in that percentage only to the extent that it has received instructions to such effect from the Beneficial Holders of the Debentures or the Depository Participants, and has delivered such instructions to the Trustee.

(4) Whenever a notice or other communication is required to be provided to Debentureholders, unless and until definitive certificate(s) have been issued to Beneficial Holders of the Debentures pursuant to this Section Section 3.1, the Trustee shall provide all such notices and communications to the Depository for forwarding by the Depository to such Beneficial Holders in accordance with Applicable Securities Legislation. Upon the termination of the book-entry only registration system or book based entry, as applicable, on the occurrence of one of the conditions specified in Section Section 3.1(2) with respect to a series of Debentures issued hereunder, the Trustee shall notify all applicable Depository Participants and Beneficial Holders, through the Depository, of the availability of definitive Debenture certificates. Upon surrender by the Depository of the certificate(s) representing the Global Debentures and receipt of new registration instructions from the Depository, the Trustee shall deliver the definitive Debenture certificates for such Debentures to the holders thereof in accordance with the new registration instructions and thereafter, the registration and transfer of such Debentures will be governed by Section Error! Reference source not found. and the remaining Sections of this Error! Reference source not found., as applicable.

(5) Notwithstanding any other provisions of this Indenture or the Debentures, transfers and exchanges of Debentures and beneficial interests in Global Debentures shall be made in accordance the applicable rules and guidelines of the Securities Transfer Association of Canada.

(6) Notwithstanding any provisions made in this Indenture for the issuance, certification and authentication of Debentures in physical form as Additional Debentures, Debentures or Global Debentures, the Debentures issued under the terms of this Indenture may also be issued to the Depository in book based only form, non-certificated and appearing on the register of the Trustee as a book based entry. In the absence of any physical securities being created for certification by the Corporation and authentication by the Trustee both at the initial issuance of the Debentures and at the time of any subsequent additional issuance of Debentures pursuant to the terms of a supplemental indenture, confirmation of the due issuance and validity of any Debentures shall be based upon the comparison of the Debentures in quantity and description appearing under the relevant broker’s instant deposit request identification number to the quantity and description of Debentures as detailed in the delivery order of the Corporation addressed to the Trustee and to the broker upon whose posting of the Book Based Only Debentures to the book entry records of the Depository on a non-certificated basis on which both the Corporation and the Trustee shall depend. It is the responsibility of the Corporation to make the necessary arrangements with its broker or brokers to obtain, in a timely manner, the necessary instant deposit request identification number to facilitate the issuance of non-certificated Book Based Only Debentures.

- 32 -

(7) In the establishment and maintenance of a non-certificated Book Based Only Debenture issue, the Trustee shall maintain such a record on its register for Debentures in book based form only. Transfers of Debentures appearing on the register of the Depository shall otherwise occur as provided for in this Indenture. The parties hereto further recognize that, notwithstanding the issuance of Book Based Only Debentures, conversions of Debentures shall occur as contemplated by the terms of this Indenture but the Trustee is permitted to employ whatever reasonable means it may from time to time require in order to guarantee the unhindered (but subject to the terms and conditions hereof) conversion of such Debentures appearing on the register for Debentures in book based only form by making whatever arrangements are deemed necessary by it with the Depository.

(8) At the time of the execution of this Indenture, the parties hereto understand that no declarations or other paper certificates or documentation will be required in order to effect conversions of Debentures held by Persons in the United States. If at any time subsequent to the initial issuance of Debentures it is determined by the Depository, the Trustee, the Corporation or legal counsel that physical declarations or other paper documentation are required for conversions or otherwise, the parties hereto and the Debentureholders acknowledge that the Trustee may be obliged to require the Debentures held by such Persons converting their Debentures to be certificated rather than held in book based form.

Section 3.2 Fully Registered Debentures

(1) With respect to each series of Debentures issuable as Fully Registered Debentures, the Corporation shall cause to be kept by and at the principal office of the Trustee in Vancouver, British Columbia and by the Trustee or such other registrar as the Corporation, with the approval of the Trustee, may appoint at such other place or places, if any, as may be specified in the Debentures of such series or as the Corporation may designate with the approval of the Trustee, a register in which shall be entered the names and addresses of the holders of Fully Registered Debentures and particulars of the Debentures held by them respectively and of all transfers of Fully Registered Debentures. Such registration shall be noted on the Debentures by the Trustee or other registrar unless a new Debenture shall be issued upon such transfer.

(2) No transfer of a Fully Registered Debenture shall be valid unless made on such register referred to in subsection 3.2(1) by the registered holder or such holder’s executors, administrators or other legal representatives or an attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Trustee or other registrar upon surrender of the Debentures together with a duly executed form of transfer acceptable to the Trustee upon compliance with such other reasonable requirements as the Trustee or other registrar may prescribe, or unless the name of the transferee shall have been noted on the Debenture by the Trustee or other registrar.

- 33 -

(3) Notwithstanding any other provisions in this Indenture or the Debentures, transfers and exchanges of Restricted Debentures shall be made in accordance with this Section 3.2(3):

(a)

Transfer and Exchange of Interests in a Restricted Uncertificated Debenture for Interests in an Unrestricted Uncertificated Debenture. An interest in a Restricted Uncertificated Debenture may be exchanged by any holder thereof for an interest in an Unrestricted Uncertificated Debenture or transferred to a Person who takes delivery thereof in the form of a beneficial interest in an Unrestricted Uncertificated Debenture if the Trustee receives the following:

	(i)	if the holder of such interest in a Restricted Uncertificated Debenture proposes to exchange such beneficial interest for a beneficial interest in an Unrestricted Uncertificated Debenture, a certificate from such holder in the form of Schedule E, including the certifications in item (1)(a) thereof; or

	(ii)	if the holder of such beneficial interest in a Restricted Uncertificated Debenture proposes to transfer such beneficial interest to a Person who shall take delivery thereof in the form of a beneficial interest in an Unrestricted Uncertificated Debenture, a certificate from such holder in the form of Schedule D, including the certifications in items (2) or (3) thereof;

and, in each such case set forth in this subsection 3.2(3)(a), an opinion of counsel in form reasonably acceptable to the Corporation and the Trustee to the effect that such transfer or exchange is in compliance with the 1933 Act and all applicable state securities laws.

	(b)	Transfer of Restricted Physical Debenture for Restricted Physical Debenture. A Restricted Physical Debenture may be transferred to a Person who takes delivery thereof in the form of a Restricted Physical Debenture if the Trustee receives a certificate to the effect set forth in Schedule D, including the certifications in item (1) thereof.

	(c)	Transfer and Exchange of Restricted Physical Debentures for Unrestricted Physical Debentures. A Restricted Physical Debenture may be exchanged by the holder thereof for an Unrestricted Physical Debenture or transferred to a Person who takes delivery thereof in the form of an Unrestricted Physical Debenture if the Trustee receives the following:

(i)

if the holder of such Restricted Physical Debenture proposes to exchange such Debenture for an Unrestricted Physical Debenture, a certificate from such holder in the form of Schedule E, including the certifications in item (1)(b) thereof; or

- 34 -

(ii)

if the holder of such Restricted Physical Debenture proposes to transfer such Debenture to a Person who shall take delivery thereof in the form of an Unrestricted Physical Debenture, a certificate from such holder in the form of Schedule D, including the certifications in item (2) or (3) thereof;

and, in each such case set forth in this subsection 3.2(3)(c), an opinion of counsel in form reasonably acceptable to the Corporation and the Trustee to the effect that such transfer or exchange is in compliance with the 1933 Act and all applicable state securities laws.

Except for Secured Indebtedness, any additional indebtedness for borrowed money or other obligations or liabilities or other debts will be subordinated to the Debentures.

Section 5.13 Right of Debentureholder to Convert Not Impaired

The subordination of the Debentures to the Secured Indebtedness and the provisions of this Article 5 do not impair in any way the right of a Debentureholder to convert its Debentures pursuant to Article 6 provided that there is no continuing default or event under Secured Indebtedness or acceleration of Secured Indebtedness that has not been rescinded and provided that such conversion does not result in a payment that could reasonably be expected to cause a default or event of default under any Secured Indebtedness.

Section 5.14 Invalidated Payments

In the event that any of the Secured Indebtedness shall be paid in full and subsequently, for whatever reason, such formerly paid or satisfied Secured Indebtedness becomes unpaid or unsatisfied, the terms and conditions of this Article 5 shall be reinstated and the provisions of this Article shall again be operative until all Secured Indebtedness is repaid in full, provided that such reinstatement shall not give the Secured Creditors any rights or recourses against the Trustee or the Debentureholders for amounts paid to the Debentureholders subsequent to such payment or satisfaction in full and prior to such reinstatement.

- 43 -

Section 5.15 Contesting Security

The Trustee, for itself and on behalf of the Debentureholders, agrees that it shall not contest or bring into question the validity, perfection or enforceability of any of the Secured Indebtedness, the Senior Security or the relative priority of the Senior Security.

(2) For the purposes of this Article, a Debenture shall be deemed to be surrendered for conversion on the date (herein called the “Date of Conversion”) on which it is so surrendered when the register of the Trustee is open and in accordance with the provisions of this Article or, in the case of an Uncertificated Debenture which the Trustee received notice of and all necessary documentation in respect of the exercise of the conversion rights and, in the case of a Debenture so surrendered by mail or other means of transmission, on the date on which it is received by the Trustee at one of its offices specified in subsection 6.4(1); provided that if a Debenture is surrendered for conversion on a day on which the register of Common Shares is closed, the Person or Persons entitled to receive Common Shares shall become the holder or holders of record of such Common Shares as at the date on which such registers are next reopened.

(3) Any part, being $1,000 or an integral multiple thereof, of a Debenture in a denomination in excess of $1,000 may be converted as provided in this Article and all references in this Indenture to conversion of Debentures shall be deemed to include conversion of such parts.

Section 6.5 Adjustment of Conversion Price

The Conversion Price in effect at any date shall be subject to adjustment from time to time as set forth below.

(a)

If and whenever at any time prior to the Time of Expiry the Corporation shall

	(i)	subdivide or redivide the outstanding Common Shares into a greater number of shares,

	(ii)	reduce, combine or consolidate the outstanding Common Shares into a smaller number of shares, or

	(iii)	issue Common Shares to the holders of all or substantially all of the outstanding Common Shares by way of a dividend or distribution (other than the issue of Common Shares to holders of Common Shares who have elected to receive dividends or distributions in the form of Common Shares in lieu of cash dividends or cash distributions paid in the ordinary course on the Common Shares),

the Conversion Price in effect on the effective date of such subdivision, redivision, reduction, combination or consolidation or on the record date for such issue of Common Shares by way of a dividend or distribution, as the case may be, shall in the case of any of the events referred to in (i) and (iii) above be decreased in proportion to the number of outstanding Common Shares resulting from such subdivision, redivision or dividend, or shall, in the case of any of the events referred to in (ii) above, be increased in proportion to the number of outstanding Common Shares resulting from such reduction, combination or consolidation. Such adjustment shall be made successively whenever any event referred to in this subsection 6.5(a) shall occur. Any such issue of Common Shares by way of a dividend or distribution shall be deemed to have been made on the record date for the dividend or distribution for the purpose of calculating the number of outstanding Common Shares under subsections (c) and (d) of this Section 6.5.

- 46 -

	(b)	If and whenever at any time prior to the Time of Expiry the Corporation shall fix a record date for the payment of a cash dividend or distribution to the holders of all or substantially all of the outstanding Common Shares, the Conversion Price shall be adjusted immediately after such record date so that it shall be equal to the price determined by multiplying the Conversion Price in effect on such record date by a fraction, of which the denominator shall be the Current Market Price on such record date and of which the numerator shall be the Current Market Price on such record date minus the amount in cash per Common Share distributed to holders of Common Shares. Such adjustment shall be made successively whenever such a record date is fixed. To the extent that any such cash dividend or distribution is not paid, the Conversion Price shall be re-adjusted to the Conversion Price which would then be in effect if such record date had not been fixed.

	(c)	If and whenever at any time prior to the Time of Expiry the Corporation shall fix a record date for the issuance of options, rights 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 into Common Shares) at a price per share (or having a conversion or exchange price per share) less than 95% of the Current Market Price on such record date, the Conversion Price shall be adjusted immediately after such record date so that it shall equal the price determined by multiplying the Conversion 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 securities so offered) by such 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 securities so offered are convertible). Such adjustment shall be made successively whenever such a record date is fixed. To the extent that any such options, rights or warrants are not so issued or any such options, rights or warrants are not exercised prior to the expiration thereof, the Conversion Price shall be re-adjusted to the Conversion Price which would then be in effect if such record date had not been fixed or to the Conversion Price which would then be in effect based upon the number of Common Shares (or securities convertible into Common Shares) actually issued upon the exercise of such options, rights or warrants were included in such fraction, as the case may be.

(d)

If and whenever at any time prior to the Time of Expiry, there is a reclassification of the Common Shares or a capital reorganization of the Corporation other than as described in subsection 6.5(a) or a consolidation, amalgamation, arrangement, binding share exchange, merger of the Corporation with or into any other Person or other entity or acquisition of the Corporation or other combination pursuant to which the Common Shares are converted into or acquired for cash, securities or other property; or a sale or conveyance of the property and assets of the Corporation as an entirety or substantially as an entirety to any other Person (other than a direct or indirect wholly-owned subsidiary of the Corporation) or other entity or a liquidation, dissolution or winding-up of the Corporation (any such event, a “Merger Event”), any holder of a Debenture who has not exercised its right of conversion prior to the effective date of such reclassification, capital reorganization, consolidation, amalgamation, arrangement, merger, share exchange, acquisition, combination, sale or conveyance or liquidation, dissolution or winding-up, upon the exercise of such right thereafter, shall be entitled to receive and shall accept, in lieu of the number of Common Shares then sought to be acquired by it, such amount of cash or the number of shares or other securities or property of the Corporation or of the Person or other entity resulting from such merger, amalgamation, arrangement, acquisition, combination or consolidation, or to which such sale or conveyance may be made or which holders of Common Shares receive pursuant to such liquidation, dissolution or winding-up, as the case may be, that such holder of a Debenture would have been entitled to receive on such reclassification, capital reorganization, consolidation, amalgamation, arrangement, merger, share exchange, acquisition, combination, sale or conveyance or liquidation, dissolution or winding-up, if, on the record date or the effective date thereof, as the case may be, the holder had been the registered holder of the number of Common Shares sought to be acquired by it and to which it was entitled to acquire upon the exercise of the conversion right, subject to subsection 6.5(m) . If determined appropriate by the Board of Directors, to give effect to or to evidence the provisions of this subsection 6.5(d), the Corporation, its successor, or such purchasing Person or other entity, as the case may be, shall, prior to or contemporaneously with any such reclassification, capital reorganization, consolidation, amalgamation, arrangement, merger, share exchange, acquisition, combination, sale or conveyance or liquidation, dissolution or winding-up, 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 holder of Debentures 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 cash, shares or other securities or property to which a holder of Debentures is entitled on the exercise of its acquisition rights thereafter. Any indenture entered into between the Corporation and the Trustee pursuant to the provisions of this subsection 6.5(d) shall be a supplemental indenture entered into pursuant to the provisions of Article 16. Any indenture entered into between the Corporation, any successor to the Corporation or such purchasing Person or other entity and the Trustee shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided in this subsection 6.5(d) and which shall apply to successive reclassifications, capital reorganizations, amalgamations, consolidations, mergers, share exchanges, acquisitions, combinations, sales or conveyances. For greater certainty, nothing in this subsection 6.5(d) shall affect or reduce the requirement for any Person to make a Change of Control Offer, and notice of any transaction to which this subsection 6.5(d) applies shall be given in accordance with Section 6.10.

- 48 -

The Corporation shall not become a party to any Merger Event unless its terms are consistent with this subsection 6.5(d) .

	(e)	If the Corporation shall make a distribution to all or substantially all of the holders of Common Shares of shares in the capital of the Corporation, other than Common Shares, or evidences of indebtedness or other assets of the Corporation, including securities (but excluding (i) any issuance of rights or warrants for which an adjustment was made pursuant to subsection 6.5(c), and (ii) any dividend or distribution paid exclusively in cash for which an adjustment was made pursuant to subsection 6.5(b)) (the “Distributed Securities”), then in each such case (unless the Corporation at its option chooses to distribute such Distributed Securities to the holders of Debentures on such dividend or distribution date (as if each holder had converted such Debenture into Common Shares immediately preceding the record date with respect to such distribution)) the Conversion Price in effect immediately preceding the ex-distribution date fixed for the dividend or distribution shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately preceding such ex-distribution date by a fraction of which the denominator shall be the five-day VWAP immediately prior to the ex-distribution date and of which the numerator shall be the five-day VWAP for the first five trading days that occur immediately post the ex- distribution date. Such adjustment shall be made successively whenever any such distribution is made and shall become effective five Business Days immediately after the ex-distribution date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price that would then be in effect if such dividend or distribution had not been declared.

		Notwithstanding the foregoing, if the securities distributed by the Corporation to all holders of its Common Shares consist of capital stock of, or similar equity interests in, a Subsidiary or other business of the Corporation (the “Spinoff Securities”), the Conversion Price shall be adjusted, unless the Corporation makes an equivalent distribution to the holders of Debentures, so that the same shall be equal to the rate determined by multiplying the Conversion Price in effect on the record date fixed for the determination of shareholders entitled to receive such distribution by a fraction, the denominator of which shall be the sum of (A) the weighted average trading price of one Common Share over the 20 consecutive trading day period (the “Spinoff Valuation Period”) commencing on and including the fifth trading day after the date on which ex- dividend trading commences for such distribution on the TSX (or such other exchange on which the Common Shares are then listed) and (B) the product of (i) the weighted average trading price (calculated in substantially the same way as the Current Market Price is calculated for the Common Shares) over the Spinoff Valuation Period of the Spinoff Securities or, if no such prices are available, the fair market value of the Spinoff Securities as reasonably determined by the Board of Directors (which determination shall be conclusive and shall be evidenced by an Officer’s Certificate delivered to the Trustee) multiplied by (ii) the number of Spinoff Securities distributed in respect of one Common Share and the numerator of which shall be the weighted average trading price of one Common Share over the Spinoff Valuation Period, such adjustment to become effective immediately preceding the opening of business on the 25th trading day after the date on which ex-dividend trading commences; provided, however, that the Corporation may in lieu of the foregoing adjustment elect to make adequate provision so that each holder of Debentures shall have the right to receive upon conversion thereof the amount of such Spinoff Securities that such holder of Debentures would have received if such Debentures had been converted on the record date with respect to such distribution.

- 49 -

(f)

If any issuer bid made by the Corporation or any of its Subsidiaries for all or any portion of Common Shares shall expire, then, if the issuer bid shall require the payment to shareholders of consideration per Common Share having a fair market value (determined as provided below) that exceeds the Current Market Price on the last date (the “Expiration Date”) tenders could have been made pursuant to such issuer bid (as it may be amended) (the last time at which such tenders could have been made on the Expiration Date is hereinafter sometimes called the “Expiration Time”), the Conversion Price shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Price in effect immediately preceding the close of business on the Expiration Date by a fraction of which (i) the denominator shall be the sum of (A) the fair market value of the aggregate consideration (the fair market value as determined by the Board of Directors, whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officer’s Certificate delivered to the Trustee) payable to shareholders based on the acceptance (up to any maximum specified in the terms of the issuer bid) of all Common Shares validly tendered and not withdrawn as of the Expiration Time (the Common Shares deemed so accepted, up to any such maximum, being referred to as the “Purchased Common Shares”) and (B) the product of the number of Common Shares outstanding (less any Purchased Common Shares and excluding any Common Shares held in the treasury of the Corporation) at the Expiration Time and the Current Market Price on the Expiration Date and (ii) the numerator of which shall be the product of the number of Common Shares outstanding (including Purchased Common Shares but excluding any Common Shares held in the treasury of the Corporation) at the Expiration Time multiplied by the Current Market Price on the Expiration Date, such increase to become effective immediately preceding the opening of business on the day following the Expiration Date. In the event that the Corporation is obligated to purchase Common Shares pursuant to any such issuer bid, but the Corporation is permanently prevented by applicable law from effecting any or all such purchases or any or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would have been in effect based upon the number of Common Shares actually purchased, if any. If the application of this subsection 6 . 5 ( f ) to any issuer bid would result in a decrease in the Conversion Price, no adjustment shall be made for such issuer bid under this subsection 6.5(f) .

- 50 -

For purposes of this subsection 6.5(f), the term “issuer bid” shall mean an issuer bid under Applicable Securities Legislation or a take-over bid under Applicable Securities Legislation by a Subsidiary of the Corporation for the Common Shares and all references to “purchases” of Common Shares in issuer bids (and all similar references) shall mean and include the purchase of Common Shares in issuer bids and all references to “tendered Common Shares” (and all similar references) shall mean and include Common Shares tendered in issuer bids.

	(g)	In any case in which this Section 6.5 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 holder of any Debenture converted after such record date and before the occurrence of such event the additional Common Shares issuable upon such conversion by reason of the adjustment required by such event before giving effect to such adjustment; provided, however, that the Corporation shall deliver to such holder an appropriate instrument evidencing such holder’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 Date of Conversion or such later date as such holder would, but for the provisions of this subsection 6.5(g), have become the holder of record of such additional Common Shares pursuant to subsection 6.4(2).

	(h)	The adjustments provided for in this Section 6.5 are cumulative and shall apply to successive subdivisions, redivisions, reductions, combinations, consolidations, distributions, issues or other events resulting in any adjustment under the provisions of this Section, provided that, notwithstanding any other provision of this Section, no adjustment of the Conversion Price shall be required unless such adjustment would require an increase or decrease of at least 1% in the Conversion Price then in effect; provided however, that any adjustments which by reason of this subsection 6.5(h) are not required to be made shall be carried forward and taken into account in any subsequent adjustment.

- 51 -

	(i)	For the purpose of calculating the number of Common Shares outstanding, Common Shares owned by or for the benefit of the Corporation shall not be counted.

	(j)	In the event of any question arising with respect to the adjustments provided in this Section 6.5, such question shall be conclusively determined by a firm of nationally recognized chartered accountants appointed by the Corporation and acceptable to the Trustee (who may be the Auditors of the Corporation); such accountants shall have access to all necessary records of the Corporation and such determination shall be binding upon the Corporation, the Trustee, and the Debentureholders.

	(k)	In case the Corporation shall take any action affecting the Common Shares other than action described in this Section 6.5, which in the opinion of the Board of Directors, would materially affect the rights of Debentureholders, the Conversion Price shall be adjusted in such manner and at such time, by action of the Board of Directors, as the Board of Directors, in their sole discretion may determine to be equitable in the circumstances. Failure of the directors to make such an adjustment shall be conclusive evidence that they have determined that it is equitable to make no adjustment in the circumstances.

	(l)	No adjustment in the Conversion Price shall be made in respect of any event described in subsections 6.5(a), 6.5(b), 6.5(c), 6.5(e) or 6.5(f) other than the events described in clauses 6.5(a)(i) or 6.5(a)(ii) if the holders of the Debentures are entitled to participate in such event on the same terms mutatis mutandis as if they had converted their Debentures prior to the effective date or record date, as the case may be, of such event.

	(m)	Except as stated above in this Section 6.5, no adjustment will be made in the Conversion Price for any Debentures as a result of the issuance of Common Shares at less than the Current Market Price on the date of issuance or the then applicable Conversion Price.

	(n)	Notwithstanding any of the foregoing in this Section 6.5, if a holder of a Debenture would otherwise be entitled to receive, upon conversion of the Debenture, any property (including cash) or securities that would not constitute “prescribed securities” for the purposes of clause 212(1)(b)(vii)(E) of the Tax Act as it applied on December 31, 2007 (“Ineligible Consideration”), such holder of a Debenture shall not be entitled to receive such Ineligible Consideration and the Corporation or the successor or acquirer, as the case may be, shall have the right (at the sole option of the Corporation or the successor or acquirer, as the case may be) to deliver to such holder “prescribed securities” for the purposes of clause 212(1)(b)(vii)(E) of the Tax Act as it applied on December 31, 2007 with a market value (as conclusively determined by the Board of Directors) equal to the market value of such Ineligible Consideration.

- 52 -

Section 6.6 No Requirement to Issue Fractional Common Shares

The Corporation shall not be required to issue fractional Common Shares upon the conversion of Debentures pursuant to this Article. If more than one Debenture shall be surrendered for conversion at one time by the same holder, the number of whole Common Shares issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of such Debentures to be converted. If any fractional interest in a Common Share would, except for the provisions of this Section, be deliverable upon the conversion of any principal amount of Debentures, the Corporation shall, in lieu of delivering any certificate representing such fractional interest, make a cash payment to the holder of such Debenture of an amount equal to the fractional interest which would have been issuable multiplied by the Current Market Price, provided, however, the Corporation shall not be required to make any payment of less than $1.00.

Section 6.7 Forced Conversion

If, beginning on that date that is four months and one day following the closing of the Offering and prior to the Maturity Date, the VWAP of the Common Shares on the TSX (or such other Canadian stock exchange on which the Common Shares are listed for trading) for 10 consecutive trading days equals or exceeds $9.00, as adjusted in accordance with Section 6.5, the Corporation may force conversion of all but not less than all of the principal amount (less any tax required by law to be deducted or withheld) of the Debenture at the Conversion Price, upon giving the Debentureholders 30 days advance written notice by way to the Trustee in accordance with Section 13.3 (the “Forced Conversion Notice”) and concurrently issuing a news release. The Corporation shall pay all accrued and unpaid interest (less any tax required by law to be deducted or withheld) in cash. The holder of a Debenture may convert such Debenture in whole or in part into Common Share until 4:30 p.m. (Vancouver time) on the Business Day prior to the date the Debenture is forced to convert in the manner provided in Section 6.4.

In the event that the Corporation exercises its right to force conversion of all of the the principal amount of the Debentures pursuant to this Section 6.7, the effective date for the forced conversion (the “Forced Conversion Date”) shall be: (a) the date stipulated in the Forced Conversion Notice; or (b) if no date is so stipulated in the Forced Conversion Notice, the date that is 30 days following the date of such Forced Conversion Notice, and upon such Forced Conversion Date: (i) all of the principal amount (less any tax required by law to be deducted or withheld) of the Debentures shall be deemed to be converted into Common Shares at the then applicable Conversion Price; and (ii) the Debentureholders shall be entered in the books of the Corporation as at the Forced Conversion Date as the holder of the number of Common Shares, as applicable, into which the Debentures held by them are convertible. Upon the surrender of Debenture Certificates to the Trustee at its principal office in the City of Vancouver, at ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇^▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇ ▇▇▇, by the Debentureholders, or in the case of Uncertificated Debentures, the surrender of interests in the Debentures through the Depository’s non-certificated system, the Corporation shall deliver to the Debentureholders certificates for the Common Shares or deposit Common Shares through the Depository’s non-certificated system, as applicable, for the Common Shares into which the Debentures held by them have been converted.

- 53 -

Section 6.8 Corporation to Reserve Common Shares

The Corporation covenants with the Trustee that it will at all times reserve and keep available out of its authorized Common Shares (if the number thereof is or becomes limited), solely for the purpose of issue upon conversion of Debentures as in this Article provided, and conditionally allot to Debentureholders who may exercise their conversion rights hereunder, such number of Common Shares as shall then be issuable upon the conversion of all outstanding Debentures. The Corporation covenants with the Trustee that all Common Shares which shall be so issuable shall be duly and validly issued as fully-paid and non-assessable.

Section 6.9 Cancellation of Converted Debentures

Subject to the provisions of Section 6.4 as to Debentures converted in part, all Debentures converted in whole or in part under the provisions of this Article shall be forthwith delivered to and cancelled by the Trustee and no Debenture shall be issued in substitution for those converted.

Section 6.10 Certificate as to Adjustment

The Corporation shall from time to time immediately after the occurrence of any event which requires an adjustment or readjustment as provided in Section 6.5, deliver an Officer’s Certificate to the Trustee specifying the nature of the event requiring the same and the amount of the adjustment necessitated thereby and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based, which certificate and the amount of the adjustment specified therein shall be verified by an opinion of a firm of nationally recognized chartered accountants appointed by the Corporation and acceptable to the Trustee (who may be the Auditors of the Corporation) and shall be conclusive and binding on all parties in interest. When so approved, the Corporation shall, except in respect of any subdivision, redivision, reduction, combination or consolidation of the Common Shares, forthwith give notice to the Debentureholders in the manner provided in Section 13.2 specifying the event requiring such adjustment or readjustment and the results thereof, including the resulting Conversion Price; provided that, if the Corporation has given notice under this Section 6.10 covering all the relevant facts in respect of such event and if the Trustee approves, no such notice need be given under this Section 6.10.

Section 6.11 Notice of Special Matters

(1) The Corporation covenants with the Trustee that so long as any Debenture remains outstanding, it will give notice to the Trustee, and to the Debentureholders in the manner provided in Section 13.2, of its intention to fix a record date for any event referred to in subsections 6.5(a), 6.5(b), 6.5(c), 6.5(d) or 6.5(e) (other than the subdivision, redivision, reduction, combination or consolidation of its Common Shares) which may give rise to an adjustment in the Conversion Price, and, in each case, such notice shall specify the particulars of such event and the record date and the effective date for such event; provided that the Corporation shall only be required to specify in such notice such particulars of such event as shall have been fixed and determined on the date on which such notice is given. Such notice shall be given not less than 14 days in each case prior to such applicable record date.

- 54 -

(2) In addition, the Corporation covenants with the Trustee that so long as any Debenture remains outstanding, it will give notice to the Trustee, and to the Debentureholders in the manner provided in Section 13.2, at least 30 days prior to the (i) effective date of any transaction referred to in Section 6.5(d) stating the consideration into which the Debentures will be convertible after the effective date of such transaction, and (ii) Expiration Date of any transaction referred to in subsection 6.5(f) stating the consideration paid per Common Share in such transaction.

Section 6.12 Protection of Trustee

The Trustee:

	(a)	shall not at any time be under any duty or responsibility to any Debentureholder to determine whether any facts exist which may require any adjustment in the Conversion Price, 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;

	(b)	shall not be accountable with respect to the validity or value (or the kind or amount) of any Common Shares or of any shares or other securities or property which may at any time be issued or delivered upon the conversion of any Debenture; and

	(c)	shall not be responsible for any failure of the Corporation to make any cash payment or to issue, transfer or deliver Common Shares or share certificates upon the surrender of any Debenture for the purpose of conversion, or to comply with any of the covenants contained in this Article.

Section 6.13 Restricted CUSIP or U.S. Legend on Certain Common Shares

Each Common Share issued upon conversion of Debentures represented by the Restricted Debentures shall be represented by a certificate with a restricted CUSIP for Common Shares and each certificate representing Common Shares issued upon conversion of Debentures bearing the U.S. Legend shall have imprinted or otherwise reproduced thereon such legend or legends in substantially the form of Schedule C attached hereto; provided that if such Common Shares are being sold in compliance with the requirements of Rule 904 of Regulation S and in compliance with local laws and regulations, and provided that the Corporation is a “foreign issuer” within the meaning of Regulation S at the time of issuance of such Common Shares, the U.S. Legend may be removed or the Common Shares may be transferred from the restricted CUSIP by providing a declaration to the Trustee, as registrar and transfer agent for the Common Shares, substantially as set forth in Schedule D (or as the Corporation or the Trustee may prescribe from time to time), together with any other evidence reasonably requested by the Corporation or Trustee, which evidence may include an opinion of counsel of recognized standing, in form and substance reasonably satisfactory to the Corporation and the Trustee, to the effect that the transfer is being made in compliance with Rule 904 of Regulation S; and provided further that, if any such Common Shares are being sold in accordance with Rule 144 under the 1933 Act, Common Shares may be transferred from the restricted CUSIP or the U.S. Legend may be removed by delivery to the Trustee, as registrar and transfer agent for the Common Shares, of an opinion of counsel of recognized standing, in form and substance reasonably satisfactory to the Trustee and the Corporation, that the transfer out of the restricted CUSIP is permissible or that the U.S. Legend is no longer required under applicable requirements of the 1933 Act or applicable state securities laws. Provided that the Trustee obtains confirmation from the Corporation that such counsel is satisfactory to it, it shall be entitled to rely on such opinion of counsel without further inquiry.

If the Corporation is so required to withhold or deduct any amount for, or on account of, Withholding Taxes from any payment made under or with respect to the Debentures, the Corporation shall deduct and withhold such Withholding Taxes from any payment to be made or with respect to the Debentures and, provided that the Corporation forthwith remits such amount to the relevant governmental authority or agency, the amount of any such deduction or withholding will be considered an amount paid in satisfaction of the Corporation’s obligations under the Debentures. There is no obligation on the Corporation to gross-up or pay additional amounts to a holder of Debentures in respect of such deductions or withholdings. For greater certainty, if any amount is required to be deducted or withheld in respect of Withholding Taxes upon a conversion of a Debenture, the Corporation shall be entitled to liquidate such number of Common Shares (or other securities) issuable as a result of such conversion as shall be necessary in order to satisfy such requirement.

then: (i) in each and every such event listed above, the Trustee may, in its discretion, but subject to the provisions of this Section, and shall, upon receipt of a request in writing signed by the holders of not less than 25% in principal amount of the Debentures then outstanding (or if the Event of Default shall exist only in respect of one or more series of the Debentures then outstanding, then upon receipt of a request in writing signed by the holders of not less than 25% in principal amount of the Debentures of such series then outstanding), subject to the provisions of Section 8.3, by notice in writing to the Corporation declare the principal of and interest and premium, if any, on all Debentures then outstanding and all other monies outstanding hereunder to be due and payable and the same shall thereupon forthwith become immediately due and payable (or, if the Event of Default shall exist only in respect of one or more series of the Debentures then outstanding, then the Trustee may declare due and payable the principal and interest and premium, if any, only with respect to such Debentures in respect of which there is an Event of Default) to the Trustee, and (ii) on the occurrence of an Event of Default under clauses 8.1(1)(e), 8.1(1)(f), 8.1(1)(g) or 8.1(1)(i), the principal of and interest and premium, if any, on all Debentures then outstanding hereunder and all other monies outstanding hereunder, shall automatically without any declaration or other act on the part of the Trustee or any Debentureholder become immediately due and payable to the Trustee and, in either case, upon such amounts becoming due and payable in either (i) or (ii) above, the Corporation shall forthwith pay to the Trustee for the benefit of the Debentureholders such principal, accrued and unpaid interest and premium, if any, and interest on amounts in default on such Debenture and all other monies outstanding hereunder, together with subsequent interest at the rate borne by the Debentures on such principal, interest, premium and such other monies from the date of such declaration or event until payment is received by the Trustee, such subsequent interest to be payable at the times and places and in the manner mentioned in and according to the tenor of the Debentures.

- 60 -

(2) For greater certainty, for the purposes of this Section 8.1, a series of Debentures shall be in default in respect of an Event of Default if such Event of Default relates to a default in the payment of principal, premium, if any, or interest on the Debentures of such series in which case references to Debentures in this Section 8.1 refer to Debentures of that particular series.

(3) For purposes of this Article 8, where the Event of Default refers to an Event of Default with respect to a particular series of Debentures as described in this Section 8.1, then this Article 8 shall apply mutatis mutandis to the Debentures of such series and references in this Article 8 to the Debentures shall mean Debentures of the particular series and references to the Debentureholders shall refer to the Debentureholders of the particular series, as applicable.

- 61 -

When notice of the occurrence of an Event of Default has been given and the Event of Default is thereafter cured, notice that the Event of Default is no longer continuing shall be given by the Trustee to the Debentureholders within 15 days after the Trustee becomes aware the Event of Default has been cured.

Section 8.3 Waiver of Default

(1) Upon the happening of any Event of Default hereunder:

	(a)	the holders of the Debentures shall have the power (in addition to the powers exercisable by Extraordinary Resolution as hereinafter provided) by requisition in writing by the holders of more than 50% of the principal amount of Debentures then outstanding, to instruct the Trustee to waive any Event of Default and to cancel any declaration made by the Trustee pursuant to Section 8.1 and the Trustee shall thereupon waive the Event of Default and cancel such declaration, or either, upon such terms and conditions as shall be prescribed in such requisition; provided that notwithstanding the foregoing if the Event of Default has occurred by reason of the non-observance or non-performance by the Corporation of any covenant applicable only to one or more series of Debentures, then the holders of more than 50% of the principal amount of the outstanding Debentures of that series shall be entitled to exercise the foregoing power and the Trustee shall so act and it shall not be necessary to obtain a waiver from the holders of any other series of Debentures; and

	(b)	the Trustee, so long as it has not become bound to declare the principal and interest on the Debentures then outstanding to be due and payable, or to obtain or enforce payment of the same, shall have power to waive any Event of Default if, in the Trustee’s opinion, the same shall have been cured or adequate satisfaction made therefor, and in such event to cancel any such declaration theretofore made by the Trustee in the exercise of its discretion, upon such terms and conditions as the Trustee may deem advisable.

- 62 -

(2) The Trustee shall be entitled and empowered, either in its own name or as Trustee of an express trust, or as attorney-in-fact for the holders of the Debentures, or in any one or more of such capacities, to file such proof of debt, amendment of proof of debt, claim, petition or other document as may be necessary or advisable in order to have the claims of the Trustee and of the holders of the Debentures allowed in any insolvency, bankruptcy, liquidation or other judicial proceedings relative to the Corporation or its creditors or relative to or affecting its property. The Trustee is hereby irrevocably appointed (and the successive respective holders of the Debentures by taking and holding the same shall be conclusively deemed to have so appointed the Trustee) the true and lawful attorney-in-fact of the respective holders of the Debentures with authority to make and file in the respective names of the holders of the Debentures or on behalf of the holders of the Debentures as a class, subject to deduction from any such claims of the amounts of any claims filed by any of the holders of the Debentures themselves, any proof of debt, amendment of proof of debt, claim, petition or other document in any such proceedings and to receive payment of any sums becoming distributable on account thereof, and to execute any such other papers and documents and to do and perform any and all such acts and things for and on behalf of such holders of the Debentures, as may be necessary or advisable in the opinion of the Trustee, in order to have the respective claims of the Trustee and of the holders of the Debentures against the Corporation or its property allowed in any such proceeding, and to receive payment of or on account of such claims; provided, however, that subject to Section 8.3, nothing contained in this Indenture shall be deemed to give to the Trustee, unless so authorized by Extraordinary Resolution, any right to accept or consent to any plan of reorganization or otherwise by action of any character in such proceeding to waive or change in any way any right of any Debentureholder.

(3) The Trustee shall also have the power at any time and from time to time to institute and to maintain such suits and proceedings as it may be advised shall be necessary or advisable to preserve and protect its interests and the interests of the Debentureholders.

(4) All rights of action hereunder may be enforced by the Trustee without the possession of any of the Debentures or the production thereof on the trial or other proceedings relating thereto.

(5) Any such suit or proceeding instituted by the Trustee shall be brought in the name of the Trustee as trustee of an express trust, and any recovery of judgment shall be for the rateable benefit of the holders of the Debentures subject to the provisions of this Indenture. In any proceeding brought by the Trustee (and also any proceeding in which a declaratory judgment of a court may be sought as to the interpretation or construction of any provision of this Indenture, to which the Trustee shall be a party) the Trustee shall be held to represent all the holders of the Debentures, and it shall not be necessary to make any holders of the Debentures parties to any such proceeding.

(2) The Trustee shall not be bound to apply or make any partial or interim payment of any monies coming into its hands if the amount so received by it, after reserving thereout such amount as the Trustee may think necessary to provide for the payments mentioned in subsection 8.6(1), is insufficient to make a distribution of at least 2% of the aggregate principal amount of the outstanding Debentures, but it may retain the money so received by it and invest or deposit the same as provided in Section 14.9 until the money or the investments representing the same, with the income derived therefrom, together with any other monies for the time being under its control shall be sufficient for the said purpose or until it shall consider it advisable to apply the same in the manner hereinbefore set forth.

The Trustee or the Corporation may at any time and from time to time, and the Trustee shall, on receipt of a Written Direction of the Corporation or a written request signed by the holders of not less than 25% of the principal amount of the Debentures then outstanding and upon receiving funding and being indemnified to its reasonable satisfaction by the Corporation or by the Debentureholders signing such request against the costs which may be incurred in connection with the calling and holding of such meeting, convene a meeting of the Debentureholders. In the event of the Trustee failing, within 30 days after receipt of any such request and such funding of indemnity, to give notice convening a meeting, the Corporation or such Debentureholders, as the case may be, may convene such meeting. Every such meeting shall be held in the City of Vancouver or at such other place as may be approved or determined by the Trustee.

Section 12.2 Notice of Meetings

(1) At least 21 days’ notice of any meeting shall be given to the Debentureholders in the manner provided in Section 13.2 and a copy of such notice shall be sent by post to the Trustee, unless the meeting has been called by it. Such notice shall state the time when and the place where the meeting is to be held and shall state briefly the general nature of the business to be transacted thereat and it shall not be necessary for any such notice to set out the terms of any resolution to be proposed or any of the provisions of this Article. The accidental omission to give notice of a meeting to any holder of Debentures shall not invalidate any resolution passed at any such meeting. A holder may waive notice of a meeting either before or after the meeting.

- 74 -

(2) If the business to be transacted at any meeting by Extraordinary Resolution or otherwise, or any action to be taken or power exercised by instrument in writing under Section 12.15, especially affects the rights of holders of Debentures of one or more series in a manner or to an extent differing in any material way from that in or to which the rights of holders of Debentures of any other series are affected (determined as provided in subsections 12.2(3) and (4)), then:

	(a)	a reference to such fact, indicating each series of Debentures in the opinion of the Trustee so especially affected (hereinafter referred to as the “especially affected series”) shall be made in the notice of such meeting, and in any such case the meeting shall be and be deemed to be and is herein referred to as a “Serial Meeting”; and

	(b)	the holders of Debentures of an especially affected series shall not be bound by

	(c)	any action taken at a Serial Meeting or by instrument in writing under Section 12.15 unless in addition to compliance with the other provisions of this Article 12:

	(i)	at such Serial Meeting: (I) there are Debentureholders present in person or by proxy and representing at least 25% in principal amount of the Debentures then outstanding of such series, subject to the provisions of this Article 12 as to quorum at adjourned meetings; and (II) the resolution is passed by the affirmative vote of the holders of more than 50% (or in the case of an Extraordinary Resolution not less than 66 %) of the principal amount of the Debentures of such series then outstanding voted on the resolution; or

	(a)	to extend the maturity of Debentures of any particular series or to reduce the principal amount thereof, the rate of interest or redemption premium thereon or to impair any conversion right thereof;

	(b)	to modify or terminate any covenant or agreement which by its terms is effective only so long as Debentures of a particular series are outstanding; or

	(c)	to reduce with respect to Debentureholders of any particular series any percentage stated in this Section 12.2 or Sections 12.4, 12.12 and 12.15;

shall be deemed to especially affect the rights of the Debentureholders of such series in a manner differing in a material way from that in which it affects the rights of holders of Debentures of any other series, whether or not a similar extension, reduction, modification or termination is proposed with respect to Debentures of any or all other series.

Section 12.3 Chairman

Some person, who need not be a Debentureholder, nominated in writing by the Trustee shall be chairman of the meeting and if no Person is so nominated, or if the Person so nominated is not present within 15 minutes from the time fixed for the holding of the meeting, a majority of the Debentureholders present in person or by proxy shall choose some Person present to be chairman.

Section 12.4 Quorum

Subject to the provisions of Section 12.12, at any meeting of the Debentureholders a quorum shall consist of Debentureholders present in person or by proxy and representing at least 25% in principal amount of the outstanding Debentures and, if the meeting is a Serial Meeting, at least 25% of the Debentures then outstanding of each especially affected series. If a quorum of the Debentureholders shall not be present within 30 minutes from the time fixed for holding any meeting, the meeting, if summoned by the Debentureholders or pursuant to a request of the Debentureholders, shall be dissolved, but in any other case the meeting shall be adjourned to the same day in the next week (unless such day is not a Business Day in which case it shall be adjourned to the next following Business Day thereafter) at the same time and place to the extent possible and no notice shall be required to be given in respect of such adjourned meeting. At the adjourned meeting, the Debentureholders present in person or by proxy shall, subject to the provisions of Section 12.12, constitute a quorum and may transact the business for which the meeting was originally convened notwithstanding that they may not represent 25% of the principal amount of the outstanding Debentures or of the Debentures then outstanding of each especially affected series. Any business may be brought before or dealt with at an adjourned meeting which might have been brought before or dealt with at the original meeting in accordance with the notice calling the same. No business shall be transacted at any meeting unless the required quorum is present at the commencement of business.

- 76 -

Section 12.5 Power to Adjourn

The chairman of any meeting at which a quorum of the Debentureholders is present may, with the consent of the holders of a majority in principal amount of the Debentures represented thereat, adjourn any such meeting and no notice of such adjournment need be given except such notice, if any, as the meeting may prescribe.

Section 12.6 Show of Hands

Every question submitted to a meeting shall, subject to Section 12.7, be decided in the first place by a majority of the votes given on a show of hands except that votes on Extraordinary Resolutions shall be given in the manner hereinafter provided. At any such meeting, unless a poll is duly demanded as herein provided, a declaration by the chairman that a resolution has been carried or carried unanimously or by a particular majority or lost or not carried by a particular majority shall be conclusive evidence of the fact. The chairman of any meeting shall be entitled, both on a show of hands and on a poll, to vote in respect of the Debentures, if any, held by him.

Section 12.7 Poll

On every Extraordinary Resolution, and on any other question submitted to a meeting when demanded by the chairman or by one or more Debentureholders or proxies for Debentureholders, a poll shall be taken in such manner and either at once or after an adjournment as the chairman shall direct. Questions other than Extraordinary Resolutions shall, if a poll be taken, be decided by the votes of the holders of a majority in principal amount of the Debentures and of each especially affected series, if applicable, represented at the meeting and voted on the poll.

Section 12.8 Voting

On a show of hands every Person who is present and entitled to vote, whether as a Debentureholder or as proxy for one or more Debentureholders or both, shall have one vote. On a poll each Debentureholder present in person or represented by a proxy duly appointed by an instrument in writing shall be entitled to one vote in respect of each $1,000 principal amount of Debentures of which he shall then be the holder. In the case of any Debenture denominated in a currency or currency unit other than Canadian dollars, the principal amount thereof for these purposes shall be computed in Canadian dollars on the basis of the conversion of the principal amount thereof at the applicable spot buying rate of exchange for such other currency or currency unit as reported by the Bank of Canada at the close of business on the Business Day next preceding the meeting. Any fractional amounts resulting from such conversion shall be rounded to the nearest $100. A proxy need not be a Debentureholder. In the case of joint holders of a Debenture, any one of them present in person or by proxy at the meeting may vote in the absence of the other or others but in case more than one of them be present in person or by proxy, they shall vote together in respect of the Debentures of which they are joint holders.

- 77 -

Section 12.9 Proxies

A Debentureholder may be present and vote at any meeting of Debentureholders by an authorized representative. The Corporation (in case it convenes the meeting) or the Trustee (in any other case) for the purpose of enabling the Debentureholders to be present and vote at any meeting without producing their Debentures, and of enabling them to be present and vote at any such meeting by proxy and of lodging instruments appointing such proxies at some place other than the place where the meeting is to be held, may from time to time make and vary such regulations as it shall think fit providing for and governing the form of the instrument appointing a proxy, which shall be in writing, and the manner in which the same shall be executed and the production of the authority of any Person signing on behalf of a Debentureholder.

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 the holders of any Debentures, or as entitled to vote or be present at the meeting in respect thereof, shall be Debentureholders and persons whom Debentureholders have by instrument in writing duly appointed as their proxies.

Section 12.10 Persons Entitled to Attend Meetings

The Corporation and the Trustee, by their respective officers and directors, the Auditors of the Corporation and the legal advisors of the Corporation, the Trustee or any Debentureholder may attend any meeting of the Debentureholders, but shall have no vote as such.

The resolution making such appointment may provide for payment of the expenses and disbursements of and compensation to such committee. Such committee shall consist of such number of persons as shall be prescribed in the resolution appointing it and the members need not be themselves Debentureholders.

Section 12.18 Concerning Serial Meetings

ARTICLE 14– CONCERNING THE TRUSTEE

Section 14.1 No Conflict of Interest

The Trustee represents to the Corporation that to the best of its knowledge at the date of execution and delivery by it of this Indenture there exists no material conflict of interest in the role of the Trustee as a fiduciary hereunder but if, notwithstanding the provisions of this Section 14.1, such a material conflict of interest exists, or hereafter arises, the validity and enforceability of this Indenture, and the Debentures issued hereunder, shall not be affected in any manner whatsoever by reason only that such material conflict of interest exists or arises but the Trustee shall, within 30 days after ascertaining that it has a material conflict of interest, either eliminate such material conflict of interest or resign in the manner and with the effect specified in Section 14.2.

Section 14.2 Replacement of Trustee

(1) The Trustee may resign its trust and be discharged from all further duties and liabilities hereunder by giving to the Corporation 90 days’ notice in writing or such shorter notice as the Corporation may accept as sufficient. If at any time a material conflict of interest exists in the Trustee’s role as a fiduciary hereunder the Trustee shall, within 30 days after ascertaining that such a material conflict of interest exists, either eliminate such material conflict of interest or resign in the manner and with the effect specified in this Section 14.2. The validity and enforceability of this Indenture and of the Debentures issued hereunder shall not be affected in any manner whatsoever by reason only that such a material conflict of interest exists. In the event of the Trustee resigning or being removed or being dissolved, becoming bankrupt, going into liquidation or otherwise becoming incapable of acting hereunder, the Corporation shall forthwith appoint a new Trustee unless a new Trustee has already been appointed by the Debentureholders. Failing such appointment by the Corporation, the retiring Trustee or any Debentureholder may apply to a Judge of the Ontario Superior Court of Justice, on such notice as such Judge may direct at the Corporation’s expense, for the appointment of a new Trustee but any new Trustee so appointed by the Corporation or by the Court shall be subject to removal as aforesaid by the Debentureholders and the appointment of such new Trustee shall be effective only upon such new Trustee becoming bound by this Indenture. Any new Trustee appointed under any provision of this Section 14.2 shall be a corporation authorized to carry on the business of a trust company in all of the Provinces of Canada. On any new appointment the new Trustee shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Trustee.

(2) Any company into which the Trustee may be merged or, with or to which it may be consolidated, amalgamated or sold, or any company resulting from any merger, consolidation, sale or amalgamation to which the Trustee shall be a party, or any company which shall purchase all or substantially all of the corporate trust book of business of the Trustee, shall be the successor trustee under this Indenture without the execution of any instrument or any further act. Nevertheless, upon the written request of the successor Trustee or of the Corporation, the Trustee ceasing to act shall execute and deliver an instrument assigning and transferring to such successor Trustee, upon the trusts herein expressed, all the rights, powers and trusts of the Trustee so ceasing to act, and, upon receipt by the Trustee of payment in full for any outstanding charges due to it, shall duly assign, transfer and deliver all property and money held by such Trustee to the successor Trustee so appointed in its place. Should any deed, conveyance or instrument in writing from the Corporation be required by any new Trustee for more fully and certainly vesting in and confirming to it such estates, properties, rights, powers and trusts, then any and all such deeds, conveyances and instruments in writing shall on request of said new Trustee, be made, executed, acknowledged and delivered by the Corporation.

- 84 -

Section 14.3 Duties of Trustee

In the exercise of the rights, duties and obligations prescribed or conferred by the terms of this Indenture, the Trustee shall act honestly and in good faith and exercise that degree of care, diligence and skill that a reasonably prudent trustee would exercise in comparable circumstances.

The Trustee may nevertheless, in its discretion, require further proof in cases where it deems further proof desirable. Without restricting the foregoing, the Trustee may rely on an opinion of Counsel satisfactory to the Trustee notwithstanding that it is delivered by a solicitor or firm which acts as solicitors for the Corporation.

Section 14.5 Evidence and Authority to Trustee, Opinions, etc.

(1) The Corporation shall furnish to the Trustee evidence of compliance with the conditions precedent provided for in this Indenture relating to any action or step required or permitted to be taken by the Corporation or the Trustee under this Indenture or as a result of any obligation imposed under this Indenture, including without limitation, the certification and delivery of Debentures hereunder, the satisfaction and discharge of this Indenture and the taking of any other action to be taken by the Trustee at the request of or on the application of the Corporation, forthwith if and when (a) such evidence is required by any other Section of this Indenture to be furnished to the Trustee in accordance with the terms of this Section 14.5, or (b) the Trustee, in the exercise of its rights and duties under this Indenture, gives the Corporation written notice requiring it to furnish such evidence in relation to any particular action or obligation specified in such notice.

(2) Such evidence shall consist of

- 85 -

	(a)	a certificate made by any two officers or directors of the Corporation, stating that any such condition precedent has been complied with in accordance with the terms of this Indenture;

	(b)	in the case of a condition precedent compliance with which is, by the terms of this Indenture, made subject to review or examination by a solicitor, an opinion of Counsel that such condition precedent has been complied with in accordance with the terms of this Indenture; and

	(c)	in the case of any such condition precedent compliance with which is subject to review or examination by auditors or accountants, an opinion or report of the Auditors of the Corporation whom the Trustee for such purposes hereby approves, that such condition precedent has been complied with in accordance with the terms of this Indenture.

Such evidence shall be, so far as appropriate, in accordance with the immediately preceding paragraph of this Section.

(4) Each statutory declaration, certificate, opinion or report with respect to compliance with a condition precedent provided for in the Indenture shall include (a) a statement by the Person giving the evidence that he has read and is familiar with those provisions of this Indenture relating to the condition precedent in question, (b) a brief statement of the nature and scope of the examination or investigation upon which the statements or opinions contained in such evidence are based, (c) a statement that, in the belief of the Person giving such evidence, he has made such examination or investigation as is necessary to enable him to make the statements or give the opinions contained or expressed therein, and (d) a statement whether in the opinion of such Person the conditions precedent in question have been complied with or satisfied.

(5) The Corporation shall furnish or cause to be furnished to the Trustee at any time if the Trustee reasonably so requires, its certificate that the Corporation has complied with all covenants, conditions or other requirements contained in this Indenture, the non-compliance with which would, with the giving of notice or the lapse of time, or both, or otherwise, constitute an Event of Default, or if such is not the case, specifying the covenant, condition or other requirement which has not been complied with and giving particulars of such non-compliance. The Corporation shall, whenever the Trustee so requires, furnish the Trustee with evidence by way of statutory declaration, opinion, report or certificate as specified by the Trustee as to any action or step required or permitted to be taken by the Corporation or as a result of any obligation imposed by this Indenture.

Subject to Sections 14.1 and 14.3, the Trustee may, in its personal or other capacity, buy, sell, lend upon and deal in the Debentures and generally contract and enter into financial transactions with the Corporation or otherwise, without being liable to account for any profits made thereby.

For certainty, in the event that this Initial Debenture is issued; (i) on or before December 31, 2017, the first interest payment will include interest accrued from November 28, 2017 to December 31, 2017, which will be equal to $5.50 for each $1,000 principal amount of the Initial Debentures; or (ii) at any time following December 31, 2017, the first interest payment will include interest accrued from November 28, 2017 to the date that this Initial Debenture is so issued and, notwithstanding anything to the contrary contained herein, shall be payable on the Business Day (as defined in the Indenture) immediately following the date of issuance.

This Initial Debenture is one of the 6.0% Unsecured Convertible Debentures (referred to herein as the “Initial Debentures”) of the Corporation issued or issuable in one or more series under the provisions of the Indenture. The Initial Debentures authorized for issue immediately are limited to an aggregate principal amount of $115,000,000 in lawful money of Canada. Reference is hereby expressly made to the Indenture for a description of the terms and conditions upon which the Initial Debentures are or are to be issued and held and the rights and remedies of the holders of the Initial Debentures and of the Corporation and of the Trustee, all to the same effect as if the provisions of the Indenture were herein set forth to all of which provisions the holder of this Initial Debenture by acceptance hereof assents.

The Initial Debentures are issuable only in denominations of $1,000 and integral multiples thereof. Upon compliance with the provisions of the Indenture, Debentures of any denomination may be exchanged for an equal aggregate principal amount of Debentures in any other authorized denomination or denominations.

Any part, being $1,000 or an integral multiple thereof, of the principal of this Initial Debenture, provided that the principal amount of this Initial Debenture is in a denomination in excess of $1,000, is convertible, at the option of the holder hereof, upon surrender of this Initial Debenture at the principal office of the Trustee in Vancouver, British Columbia, at any time prior to the close of business on the Maturity Date or, if this Initial Debenture is called for redemption on or prior to such date, then, to the extent so called for redemption, up to but not after the close of business on the last Business Day immediately preceding the date specified for redemption of this Initial Debenture or, if called for repurchase pursuant to a Change of Control (as defined in the Indenture) on the Business Day immediately prior to the payment date, into common shares of the Corporation (the “Common Shares”) (without adjustment for interest accrued hereon or for dividends or distributions on Common Shares issuable upon conversion) at a conversion price of $6.50 (the “Conversion Price”) per Common Share, being a rate of approximately 153.8462 Common Shares for each $1,000 principal amount of Initial Debentures, all subject to the terms and conditions and in the manner set forth in the Indenture. No Initial Debentures may be converted during the five Business Days preceding each of June 30 and December 31 in each year, commencing December 31, 2017, as the registers of the Trustee will be closed during such periods. The Indenture makes provision for the adjustment of the Conversion Price in the events therein specified. No fractional Common Shares will be issued on any conversion but in lieu thereof, the Corporation will satisfy such fractional interest by a cash payment equal to the market price of such fractional interest determined in accordance with the Indenture. Holders converting their Debentures will receive accrued and unpaid interest thereon. If a Debenture is surrendered for conversion on an Interest Payment Date or during the five preceding Business Days, the person or persons entitled to receive Common Shares in respect of the Debentures so surrendered for conversion shall not become the holder or holders of record of such Common Shares until the Business Day following such Interest Payment Date and, for clarity, any interest payable on such Debentures will be for the account of the holder of record of such Debentures at the close of business on the relevant record date.

Subject to the provisions in the Indenture and without further action on the part of the Registered Holder, if prior to the Maturity Date, the volume weighted average price of the Common Shares on the Toronto Stock Exchange (or such other Canadian stock exchange on which the Common Shares are listed for trading) for 10 consecutive trading days equals or exceeds $9.00, as adjusted in accordance with the Indenture, the Corporation may deliver a written notice (the “Forced Conversion Notice”) to the Trustee in accordance with the Indenture and to the Registered Holder by way of news release to cause the Registered Holder to convert all but not less than the principal amount of the Debentures (less any tax required by law to be deducted or withheld) into that number of Common Shares of the Corporation equal to the principal amount of the Debentures (less any tax required by law to be deducted or withheld) to the date of such forced conversion. The Corporation shall pay all accrued and unpaid interest in cash. The effective date for the forced conversion (the “Forced Conversion Date”) shall be: (a) the date stipulated in the Forced Conversion Notice; or (b) if no date is so stipulated in the Forced Conversion Notice, the date that is 30 days following the date of such Forced Conversion Notice, and upon such Forced Conversion Date: (i) all of the principal amount of the Debentures (less any tax required by law to be deducted or withheld) shall be deemed to be converted into Common Shares at the then applicable Conversion Price; and (ii) the registered holder shall be entered in the books of the Corporation as at the Forced Conversion Date as the holder of the number of Common Shares, as applicable, into which the Debentures are convertible. In the event that the Corporation delivers a Forced Conversion Notice, upon surrender of this Initial Debenture to the Trustee, the Corporation shall deliver certificates for the Common Shares into which the Debentures have been converted.

A - 3

Not less than 30 days prior to the consummation of: (i) any event as a result of or following which any person, or persons acting jointly or in concert directly or indirectly within the meaning of applicable securities legislation, beneficially owns or exercises control or direction over an aggregate of more than 50% of the outstanding Common Shares; or (ii) the sale or other transfer of all or substantially all of the consolidated assets of the Corporation, unless the holders of voting securities of the Corporation immediately prior to such sale, merger, reorganization or other similar transaction hold securities representing 50% or more of the voting control or direction in the Corporation or the successor entity upon completion of such merged, reorganized or other continuing entity (collectively, a “Change of Control”), the Corporation shall notify the holders of the Initial Debentures of the Change of Control, and the holders of the Initial Debentures shall, in their sole discretion, have the right to require the Corporation to, either: (i) purchase the Debentures at 104% of the principal amount thereof plus unpaid interest to the Maturity Date; or (ii) convert the Debentures at the Conversion Price (the “Change of Control Offer”). If 90% or more of the principal amount of all Debentures outstanding on the date the Corporation provides notice of a Change of Control to the Trustee have been tendered for purchase pursuant to the Change of Control Offer, the Corporation has the right to redeem all the remaining outstanding Initial Debentures on the same date and at the same price.

If an offer is made for the Initial Debentures which is a take-over bid for the Initial Debentures within the meaning of applicable Canadian securities laws and 90% or more of the principal amount of all the Initial Debentures (other than Initial Debentures held at the date of the offer by or on behalf of the Offeror, associates or affiliates of the Offeror or anyone acting jointly or in concert with the Offeror) are taken up and paid for by the Offeror, the Offeror will be entitled to acquire the Initial Debentures of those holders who did not accept the offer on the same terms as the Offeror acquired the first 90% of the principal amount of the Initial Debentures.

The indebtedness evidenced by this Initial Debenture, and by all other Initial Debentures now or hereafter certified and delivered under the Indenture, is a direct unsecured obligation of the Corporation, and is subordinated in right of payment, to the extent and in the manner provided in the Indenture, to the prior payment in full of all Secured Indebtedness, whether outstanding at the date of the Indenture or thereafter created, incurred, assumed or guaranteed.

A - 4

The Indenture contains provisions binding upon all holders of Initial Debentures outstanding thereunder (or in certain circumstances specific series of Initial Debentures) resolutions passed at meetings of such holders held in accordance with such provisions and instruments signed by the holders of a specified majority of Initial Debentures outstanding (or specific series), which resolutions or instruments may have the effect of amending the terms of this Initial Debenture or the Indenture.

The Indenture contains provisions disclaiming any personal liability on the part of holders of Common Shares and officers, directors and employees of the Corporation in respect of any obligation or claim arising out of the Indenture or this Initial Debenture.

This Initial Debenture may only be transferred, upon compliance with the conditions prescribed in the Indenture, in one of the registers to be kept at the principal office of the Trustee in the City of Vancouver and in such other place or places and/or by such other registrars (if any) as the Corporation with the approval of the Trustee may designate. No transfer of this Initial Debenture shall be valid unless made on the register by the registered holder hereof or his executors or administrators or other legal representatives, or his or their attorney duly appointed by an instrument in form and substance satisfactory to the Trustee or other registrar, and upon compliance with such reasonable requirements as the Trustee and/or other registrar may prescribe and upon surrender of this Initial Debenture for cancellation. Thereupon a new Initial Debenture or Initial Debentures in the same aggregate principal amount shall be issued to the transferee in exchange hereof.

This Initial Debenture shall not become obligatory for any purpose until it shall have been certified by the Trustee under the Indenture.

Capitalized words or expressions used in this Initial Debenture shall, unless otherwise defined herein, have the meaning ascribed thereto in the Indenture. In the event of any inconsistency between the terms of this Initial Debenture and the Indenture, the terms of the Indenture shall govern.

Ladies and Gentlemen:

In connection with its agreement to purchase debentures (the “Debentures”) of Aurora Cannabis Inc. (the “Corporation”), the undersigned purchaser acknowledges, represents to, warrants, covenants and agrees with the Corporation, as follows:

	1.	It is authorized to consummate the purchase of the Debentures.

	2.	It is a Qualified Institutional Buyer, purchasing the Debentures for its own account or for the account or benefit of one or more Qualified Institutional Buyers with respect to which it exercises sole investment discretion for investment purposes only and not with a view to any resale, distribution or other disposition of the Debentures or the Common Shares in violation of United States federal or U.S. state securities laws.

	3.	It understands and acknowledges that none of the Debentures or the Common Shares have been nor will be registered under the U.S. Securities Act or the securities laws of any state of the United States, and will, therefore, be “restricted securities” within the meaning of Rule 144 under the U.S. Securities Act that will not be represented by certificates that bear a U.S. restricted legend or identified by a restricted CUSIP number, and that the offer and sale of the Debentures to it will be made in reliance upon an exemption from registration available for offers and sales to Qualified Institutional Buyers.

	4.	It, alone or with the assistance of its professional advisors, has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of its investment in the Debentures or the Common Shares and is able, without impairing its financial condition, to hold the Debentures or the Common Shares for an indefinite period of time and to bear the economic risks, and withstand a complete loss, of such investment.

	5.	It acknowledges that it has not purchased the Debentures as a result of any “general solicitation” or “general advertising” (as those terms are used in Regulation D under the U.S. Securities Act), including, but not limited to, any advertisements, articles, notices or other communications published in any newspaper, magazine or similar media or on the Internet or broadcast over radio, television or the Internet, or any seminar or meeting whose attendees have been invited by general solicitation or general advertising.

	6.	In consideration for the receipt of unlegended “restricted securities”, it agrees that if it decides to offer, sell, pledge or otherwise transfer any of the Debentures or Common Shares, it will not offer, sell, pledge or otherwise transfer such securities, directly or indirectly, unless the transfer is: (i) to the Corporation, (ii) outside the United States in accordance with the requirements of Rule 904 of Regulation S and in compliance with applicable local laws and regulations, (iii) in compliance with an exemption from registration under the U.S. Securities Act provided by (A) Rule 144 thereunder, if available, or (B) Rule 144A, if available, and, in both cases, in accordance with applicable U.S. state securities laws, or (iv) in another transaction that does not require registration under the U.S. Securities Act or any applicable U.S. state securities laws, and, in the case of (iii)(A) and (iv) above, after it has furnished to the Corporation an opinion of counsel of recognized standing in form and substance reasonably satisfactory to the Corporation to such effect.

F - 1

	7.	It acknowledges it has implemented, or shall immediately implement, adequate internal procedures to be able to ensure compliance with the transfer restrictions and, in particular, to ensure that the Debentures and Common Shares shall be properly identified in its records as “restricted securities” that are subject to such transfer restrictions notwithstanding the absence of a U.S. restrictive legend.

	8.	It understands and acknowledges that the Corporation is not obligated to file and has no present intention of filing with the SEC or with any U.S. state securities commission any registration statement in respect of resales of any of the Debentures or Common Shares in the United States.

	9.	It understands and acknowledges that the Corporation (i) is not obligated to remain a “foreign issuer” within the meaning of Regulation S, (ii) may not, at the time of conversion of the Debentures into Common Shares, or at any other time, be a foreign issuer, and (iii) may engage in one or more transactions which could cause the Corporation not to be a foreign issuer.

	10.	It is aware that (i) purchasing, holding and disposing of the Debentures or the Common Shares may have tax consequences under the laws of Canada and the United States, and (ii) it is solely responsible for determining the tax consequences applicable to its particular circumstances and should consult its own tax advisors concerning investment in the Debentures or the Common Shares.

	11.	No agency, governmental authority, regulatory body, stock exchange or other entity (including, without limitation, the SEC or any U.S. state securities commission) has made any finding or determination as to the merit of investment in, nor have any such agencies or governmental authorities made any recommendation or endorsement with respect to, the Debentures or the Common Shares.

	12.	If required by applicable securities legislation, regulatory policy or order or by any securities commission, stock exchange or other regulatory authority, it will execute, deliver and file and otherwise assist the Corporation in filing reports, questionnaires, undertakings and other documents with respect to the issuance of the Debentures or the Common Shares.

	13.	It understands and acknowledges that it is making the representations, warranties and agreements contained herein with the intent that they may be relied upon by the Corporation in determining its eligibility to purchase the Debentures and the Common Shares.

	14.	(i) If it is acquiring any Debentures as a fiduciary or agent for one or more investor accounts, it represents that it has full power to make the representations, warranties and agreements contained herein on behalf of each such account and that the representations, warranties and agreements contained herein are true and correct and will be binding upon each such account; or (ii) the undersigned is an officer of the purchaser duly authorized to execute and deliver this letter on behalf of the purchaser.

	15.	It acknowledges and consents to the fact that the Corporation may be required by applicable securities laws to provide the securities regulators or other authorities pursuant to the Proceeds of Crime (Money Laundering) and Terrorist Financing Act (Canada) with its personal information; and, notwithstanding that it may be purchasing securities as agent on behalf of an undisclosed principal, it agrees to provide, on request, particulars as to the identity of such undisclosed principal as may be required by the Corporation in order to comply with the foregoing.

	16.	It represents and warrants that (i) the funds representing the purchase price which will be advanced by it will not represent proceeds of crime for the purposes of the United States Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act (the “PATRIOT Act”), and it acknowledges that the Corporation may in the future be required by law to disclose its name and other information, on a confidential basis, pursuant to the PATRIOT Act, and (b) no portion of the purchase price to be provided by it (i) has been or will be derived from or related to any activity that is deemed criminal under the laws of the United States of America or any other jurisdiction, or (ii) is being tendered on behalf of a person or entity that has not been identified to or by it; and it shall promptly notify the Corporation if it discovers that any of such representations ceases to be true and provide the Corporation with appropriate information in connection therewith.

F - 2

17.

It agrees that by accepting the Debentures it shall be representing and warranting that the foregoing representations and warranties are true and correct as at the closing date of the offering of the Debentures and that they shall survive the purchase by it of the Debentures and shall continue in full force and effect notwithstanding any subsequent disposition by it of the Debentures. It irrevocably authorizes the Corporation to produce this U.S. Purchaser Letter or a copy hereof to any interested party in any administrative or legal proceedings or official enquiry with respect to the matters set forth herein.

The Corporation shall be entitled to rely on delivery of an electronic mail or facsimile copy of this U.S. Purchaser Letter, and acceptance by the Corporation of an electronic mail or facsimile copy of this U.S. Purchaser Letter shall create a legal, valid and binding agreement between the Corporation and the undersigned.
