THE DEBENTURES

2.1 Form and Terms of Debentures

(a) The Debentures authorized for issue and which may be Authenticated and delivered under this Indenture are limited to an aggregate principal amount of up to $65,000,000, may only be issued upon and subject to the conditions and limitations set forth herein and shall be designated as "8.00% Secured Convertible Debentures due 2027".

 - 32 -

(b) The Debentures shall be issued in denominations of $1,000 and integral multiples of $1,000. Each 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 Debenture in accordance with Section 2.3, as conclusively evidenced by their execution of a Debenture. Each Debenture shall additionally bear such distinguishing letters and numbers as the Trustee shall approve. Notwithstanding the foregoing, a 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, including as Uncertificated Debentures in accordance with Section 2.2, or as specified in an Officer's Certificate.

The Debentures may be engraved, lithographed, printed, mimeographed or typewritten or partly in one form and partly in another.

The Debentures shall be issued in the form of definitive Debenture Certificates or as Uncertificated Debentures (unless a U.S. Legend applies), and shall bear the U.S. Legend, if applicable.

(c) The Debentures shall be dated as of the Issue Date and shall mature on the Maturity Date. Subject to the terms and conditions hereof, the outstanding principal amount of the Debentures shall be repaid by the Company to the Debentureholders on the Maturity Date, together with all accrued and unpaid interest on the outstanding principal (the "Maturity Date Payment").

(d) The Debentures shall bear interest from and including the Issue Date at the rate of 8.00% per annum (based on a year of 365 days), which shall be capitalized quarterly (on each Quarterly Date and commencing on March 31, 2023) and payable on the Maturity Date; provided that, in the event of an Event of Default, interest shall accrue at rate of 10.50%, capitalized quarterly. For the avoidance of doubt, no cash interest payments are payable until the Maturity Date. Any payment required to be made on any day that is not a Business Day will be made on the next succeeding Business Day.

(e) Upon and subject to the provisions and conditions of Article 11 and provided no Event of Default has occurred and is continuing, the Company may elect, subject to applicable regulatory approval and Applicable Securities Legislation, to satisfy all or part of the Interest Obligation on the Debentures on any Interest Payment Date (including, for greater certainty, following conversion or upon maturity or redemption) by delivering Common Shares to the Trustee.

 - 33 -

(f) In accordance with and subject to the provisions and conditions of Article 6 and Section 3.7, the holder of each Debenture shall have the right at such holder's option, at any time and from time to time following the Issue Date and prior to 5:00 p.m. (Eastern time) on the earlier of: (i) the Business Day immediately preceding the Maturity Date (the "Time of Expiry"); (ii) if subject to repurchase in accordance with the terms hereof, on the last Business Day immediately preceding the payment date applicable to such repurchase; and (iii) the date of repayment in full of the aggregate principal amount of Debentures and all accrued and unpaid interest thereon, subject to the satisfaction of certain conditions set forth herein, to convert all or any portion, being at a minimum $1,000 or an integral multiple thereof, of the principal amount Debentures into Conversion Shares at the Conversion Price in effect on the Date of Conversion.

The Conversion Price in effect on the date hereof for each Conversion Share to be issued upon the conversion of Debentures shall be the Original Conversion Price. No fractional Conversion Shares will be issued and such fractions will be rounded down to the nearest whole Conversion Share without the payment of any compensation to the holder. The Conversion Price is subject to adjustment pursuant to the provisions of Section 6.5.

Debentureholders converting their Debentures will receive, in addition to the applicable number of Conversion Shares, accrued and unpaid interest (less any taxes required to be deducted from such interest) in respect of the Debentures surrendered for conversion up to but excluding the Date of Conversion from, and including, the Issue Date.

The Conversion Price will not be adjusted for accrued interest.

A Debenture in respect of which a holder has accepted a Change of Control Offer pursuant to the provisions of subsection 2.1(h) may be surrendered for conversion only if such acceptance is withdrawn in accordance with this Indenture.

(g) Upon and subject to the provisions and conditions of Section 2.12, the Debentureholders shall have the option to elect to convert all or any portion of the accrued and unpaid interest, including, for greater certainty, any interest earned on interest previously accrued and added to the outstanding principal amount of Debentures, into Common Shares at the Holders Share Interest Conversion Price.

(h) If after 120 days after the Issue Date and prior to the Maturity Date, the VWAP of the Common Shares as measured in U.S. dollars on the NYSE American equals or exceeds 150% of the Conversion Price (as adjusted in accordance with Section 6.5) for 20 consecutive trading days, the Company shall have right to convert all but not less than all of the principal amount of the Debentures and subject to the approval of the TSX or any applicable Stock Exchange, all accrued and unpaid interest on the Debentures (including, for greater certainty, any interest earned on interest previously capitalized and added to the principal amount pursuant to Section 2.1(d); provided, however, that such conversion price of the accrued and unpaid interest must not be less than the VWAP of the Common Shares on the TSX during the five trading days immediately preceding the relevant date, less the TSX permitted discount), converted into Common Shares at the Conversion Price, upon providing a written notice to the Trustee in accordance with this Indenture (the "Forced Conversion Notice"). In the event that the Company exercises its right to force conversion, the effective date of the conversion of the Debentures (the "Forced Conversion Date") shall be the date stipulated in the Forced Conversion Notice (such date to be no later than three Business Days after the date of the Forced Conversion Notice), and upon such Forced Conversion Date: (i) all of the principal amount of the Debentures and all accrued and unpaid interest thereon (less any tax required by law to be deducted or withheld) shall be converted into Common Shares at the then-applicable Conversion Price; and (ii) the Debentureholders shall be entered in the books of the Company as at the Forced Conversion Date as the holders of the number of Common Shares, as applicable, into which the initial Debentures held by them are convertible. In connection with a Change of Control, and subject to the provisions and conditions of this subsection 2.1(h), the Company shall be obligated to offer to purchase all of the Debentures then outstanding. The terms and conditions of such obligation are set forth below:

 - 34 -

(i) Not less than 30 days following the occurrence of a Change of Control, the Company shall deliver to the Trustee, and the Trustee shall promptly deliver to the holders of the 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"), accompanied by an Officer's Certificate of the Company setting forth details of the VWAP calculation, together with a cash offer in writing (the "Change of Control Offer") to purchase on the Change of Control Purchase Date (as defined below), all (or any portion actually tendered to such offer) of the Debentures then outstanding from the holders thereof made in accordance with the requirements of Applicable Securities Legislation at a price equal to 104% of the principal amount of the Debenture (the "Offer Price") plus accrued and unpaid interest on such Debentures up to, and including, the Change of Control Purchase Date (collectively, the "Total Offer Price").

The "Change of Control Purchase Date" shall be the date that is 30 Business Days after the date that the Change of Control Notice and Change of Control Offer are delivered to holders of Debentures. Subject to Applicable Securities Legislation and Stock Exchange requirements, the Company shall have no obligation to file or prepare any registration statement, prospectus or similar document in order to permit any Debentureholder to exercise such right.

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

 - 35 -

(iii) Upon receipt of notice that the Company has exercised or is exercising the 90% Redemption Right and is acquiring the remaining Debentures, the Trustee shall promptly provide written notice, such form of notice to be provided to it by the Company, to each Debentureholder that did not previously accept the Change of Control Offer that:

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

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

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

(iv) The Company shall, on or before 11:00 a.m. (Toronto 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 by wire transfer, such sums of money as may be sufficient to pay the aggregate Total Offer Price of the Debentures to be purchased or redeemed by the Company on the Change of Control Purchase Date. The Company 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, in respect of the aggregate Total Offer Price, the Trustee shall pay or cause to be paid to the holders of such Debentures, the Total Offer Price to which they are entitled (less any tax required by law to be deducted in respect of accrued and unpaid interest).

 - 36 -

(v) In the event that one or more of such Debentures being purchased in accordance with this subsection 2.1(h) becomes subject to purchase in part only, upon surrender of such Debentures for payment of the Total Offer Price, the Company shall execute and the Trustee shall Authenticate and deliver without charge to the holder thereof or upon the holder's order, one or more new Debentures for the portion of the principal amount of the Debentures not purchased.

(vi) Debentures for which holders have accepted the Change of Control Offer and Debentures which the Company has elected to redeem in accordance with this subsection 2.1(h) shall become due and payable at the Total 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 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 the Debentures shall have been deposited as provided in this subsection 2.1(h) 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 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.

(vii) In case the holder of any Debenture to be purchased or redeemed in accordance with this subsection 2.1(h) shall fail on or before the Change of Control Purchase Date to so surrender such holder's Debenture or shall not within such time accept payment of the monies payable or give such receipt therefor, if any, as the Trustee may require, such monies may be set aside 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 so set aside and the Debentureholder shall have no other right except to receive payment of the monies so paid and deposited upon surrender and delivery of such holder's Debenture. In the event that any money required to be deposited hereunder with the Trustee or any depository or paying agent on account of the principal and/or the interest (if any) on Debentures issued hereunder shall remain so deposited for a period of four years from the Change of Control Purchase Date, then, subject to any applicable law regarding unclaimed property, such monies 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 Company upon the Company's request 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 four years after the Change of Control Purchase Date (the "Unclaimed Funds Return Date") to the Company upon receipt from the Company 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.

 - 37 -

(viii) Subject to the provisions above related to Debentures purchased in part, all Debentures redeemed and paid under this subsection 2.1(h) shall forthwith be delivered to the Trustee and cancelled and no Debentures shall be issued in substitution therefor.

For the purposes of any provision hereof requiring or permitting actions with the consent of or the direction of the 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 in CDS through Participants shall be established by law and agreements between such holders and CDS and the Participants upon instructions from the Participants. Each of the Trustee and the Company may deal with CDS for all purposes (including the making of payments for principal or interest) 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.

 - 38 -

(d) For so long as the 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 in accordance with Section 13.2.

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

(f) 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.

(g) Notwithstanding anything herein to the contrary, none of the Company nor the Trustee nor any agent thereof shall have any responsibility or liability for:

(i) 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 the Depository or its nominee);

(ii) for maintaining, supervising or reviewing any records of the Depository or any Participant relating to any such interest; or

(iii) 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.

 - 39 -

2.3 Execution of Debentures

All Debenture Certificates shall be signed (either manually or by facsimile or other electronic signature) by any one authorized director or officer of the Company 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 the foregoing, if any Person whose signature, either manual or in facsimile or electronic form, appears on a Debenture as a director or officer no longer holds 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 and enforceable against the Company and entitled to the benefits of this Indenture.

2.4 Authentication

(a) 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 Authenticated by or on behalf of the Trustee substantially in the form set out in this Indenture, in a relevant supplemental indenture, or in some other form approved by the Trustee. Such Authentication on any Debenture shall be conclusive evidence that such Debenture is duly issued, is a valid and binding obligation of the Company enforceable against the Company and the holder is entitled to the benefits hereof.

(b) The Authentication of the Trustee of the Debentures, or interim Debentures hereinafter mentioned, 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 Authentication of the Trustee on the Debentures or interim Debentures shall, however, be a representation and warranty by the Trustee that the Debentures or interim Debentures have been duly Authenticated by or on behalf of the Trustee pursuant to the provisions of this Indenture.

(c) The Trustee shall Authenticate Uncertificated Debentures (whether upon original issuance, exchange, registration of transfer or otherwise) by completing its Internal Procedures and the Company shall, and hereby acknowledges that it shall, thereupon be deemed to have duly and validly issued such Uncertificated Debentures 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 Company.

(d) The Trustee will Authenticate Debentures upon the Written Direction of the Company.

 - 40 -

2.5 Issuance and Delivery of Debentures

In Authenticating the Debentures, the Trustee shall be entitled to receive and shall be fully protected in relying and acting upon, unless and until such documents have been superseded or revoked:

(a) a Written Direction of the Company requesting certification and delivery of such Debentures and setting forth delivery instructions

(b) an opinion of Counsel to the Company addressed to the Trustee, in form and substance satisfactory to the Trustee, acting reasonably, to the effect that all legal requirements imposed by this Indenture or by law in connection with the proposed issue of Debentures have been complied with, subject to the delivery of certain documents or instruments specified in such opinion; and

(c) an Officer's Certificate certifying that the Company is not in default under this Indenture, that the terms and conditions for the certification and delivery of the Debentures, have been complied with subject to the delivery of any documents or instruments specified in such Officer's Certificate and that no Event of Default exists or will exist upon such certification and delivery.

2.6 Interim Debenture Certificates

Pending the delivery of definitive Debentures of any series to the Trustee, the Company may issue and the Trustee may Authenticate 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 Company may execute and the Trustee may Authenticate 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 Company 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 Authenticated, 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 Debenture Certificates, 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 Company shall have delivered the definitive Debenture Certificates to the Trustee, the Trustee shall cancel such temporary Debentures, if any, and shall call in for exchange all interim Debenture Certificates that shall have been issued and forthwith after such exchange shall cancel the same. No charge shall be made by the Company to the holders of such interim or temporary Debentures Certificates for the exchange thereof.

 - 41 -

2.7 Mutilation, Loss, Theft or Destruction

In case any of the Debentures issued hereunder shall become mutilated or be lost, stolen or destroyed, the Company, in its discretion, may issue, and thereupon the Trustee shall Authenticate 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 Company and to the Trustee such evidence of the loss, theft or destruction of the Debenture as shall be satisfactory to each of them in their discretion and shall also furnish an indemnity and surety bond satisfactory to each of them in their discretion. The applicant shall pay all reasonable expenses incidental to the issuance of any substituted Debenture.

2.8 Concerning Interest

(a) Except as may otherwise be provided in this Indenture or in a Written Direction of the Company and subject to Section 2.1(d) with respect to the calculation of interest in respect of the initial interest payment to be paid on the Debentures, all Debentures issued hereunder, whether originally or upon exchange or in substitution for previously issued Debentures which are interest bearing, shall bear interest from and including the Issue Date to and excluding the Interest Payment Date.

(b) Unless otherwise specifically provided in the terms of the Debentures, interest shall be computed on the basis of a year of 365 days. 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.

2.9 Rank of Debentures

The indebtedness, liabilities and obligations of the Company under this Indenture and under the Debentures, are its direct, senior unsecured obligations of the Company ranking pari passu with all other current and future senior unsecured debt and other liabilities of the Company. The indebtedness, liabilities and obligations of the Company under this Indenture and under the Debentures will be guaranteed by the Limited Recourse Guarantor with recourse limited to a pledge of all present and future shares issued by the Guarantor. The indebtedness, liabilities and obligations of the Company under this Indenture and under the Debentures will be guaranteed by the Guarantor on a full recourse basis, and such guarantee shall be secured by a first ranking security interest in and to all of the Guarantor's present and future real and personal property, including the Project.

 - 42 -

2.10 Payments of Amounts Due on Maturity

Payments of amounts due upon maturity of the Debentures will be made in the following manner. The Company 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. (Toronto time) on the Business Day immediately prior to each Maturity Date for Debentures outstanding from time to time under this Indenture, the Company will deliver to the Trustee a 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 Maturity Date Payment together with any accrued and unpaid interest thereon less any tax required by law to be deducted). The Trustee, on behalf of the Company, will pay to each holder entitled to receive payment of the principal and the interest (if any) on the Debenture, upon surrender of the Debenture at the Toronto office of the Trustee designated for such purpose from time to time by the Company 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 Company 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.

For greater certainty, it is acknowledged and agreed that under no circumstances will the Trustee be responsible for any tax withholding which may be required in connection with the Debentures. It is further acknowledged and agreed that any tax withholding in connection with the Uncertificated Debentures will be done by Participants of CDS, in accordance with their customary practices and procedures.

2.11 Payment of Interest

As interest becomes due on each Debenture (except, subject to certain exceptions set forth herein including conversion, when interest may at the option of the Company be paid upon surrender of such Debenture), the Company, either directly or through the Trustee or any agent of the Trustee, shall send or forward by prepaid ordinary mail, electronic 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 applicable Interest Record 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 Interest Payment Date. The Trustee shall only mail in advance of any Interest Payment Date if it is already in clear receipt of the funds which it is forwarding. 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 Company 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 Company 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 Company 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.

 - 43 -

In respect of Uncertificated Debentures, all payments of cash interest shall be made by wire funds transfers made payable: (i) to the Depository or its nominee, unless the Company and CDS otherwise agree; or (ii) if the Company wishes to have the Trustee act as interest paying agent, to the Trustee by no later than 11:00 a.m. on the Business Day prior to the Interest Payment Date for subsequent payment to the Depositary for payment to Beneficial Holders of the applicable Uncertificated Debenture via its participants. None of the Company, 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.

For greater certainty, it is acknowledged and agreed that under no circumstances will the Trustee be responsible for any tax withholding which may be required in connection with the Debentures. It is further acknowledged and agreed that any tax withholding in connection with the Uncertificated Debentures will be done by Participants of CDS, in accordance with their customary practices and procedures.

2.12 Right to Receive Interest under the Debentures in Common Shares

(a) A Debentureholder may, at its option, elect to receive Common Shares for all (and not less than all) of the interest (the "Holders Share Interest Payment Right") by delivering to the Corporation a Holders Share Interest Election Notice (as hereinafter defined) confirming its election to receive Common Shares for the interest. In the absence of a Holders Share Interest Election Notice from a Debentureholder, all interest will be paid in cash on the basis set forth herein.

(b) The Debentureholder shall exercise the Holders Share Interest Payment Right by so specifying in a notice (the "Holders Share Interest Election Notice") in substantially the form of Schedule "B", which shall be delivered to the Company not less than 15 days prior to the Interest Payment Date.

(c) If a Debentureholder delivers a Holders Share Interest Election Notice, the Debentureholders shall be deemed to have granted an extension of the payment of the interest for a period of 10 Business Days from the Interest Payment Date whether or not the Common Shares issuable pursuant to the Holders Share Interest Payment Right are issued. The Company shall, if required by the policies of the TSX, make application to the TSX (or such other exchange on which the Common Shares may be listed from time to time) for approval (which may be conditional) of the issue of the Common Shares to be issued under the Holders Share Interest Payment Right (the "Exchange Approval").

 - 44 -

(d) Upon written request by the Company, a Debentureholder shall provide such evidence as may be required by the Company that qualifies the Debentureholder pursuant to an exemption from the prospectus and registration requirements under Applicable Securities Legislation to purchase the Common Shares to be issued pursuant to the Holders Share Interest Payment Right.

(e) The issue of the Common Shares pursuant to the Holders Share Interest Payment Right shall be conditional upon the following conditions being met:

(i) receipt by the Company of the Exchange Approval;

(ii) the Common Shares to be issued pursuant to the Holders Share Interest Payment Right shall be exempt from the prospectus requirements of, or qualified for distribution under, Applicable Securities Legislation and payment in Common Shares shall not violate the registration requirements of Applicable Securities Legislation and the Debentureholder shall have provided at the Company's written request, such evidence as may be required by the Company that qualifies the Debentureholder pursuant to an exemption from the prospectus and registration requirements under Applicable Securities Legislation to purchase the Common Shares to be issued pursuant to the Holders Share Interest Payment Right;

(iii) the listing of such additional Common Shares on each stock exchange on which the Common Shares are then listed;

(iv) no Event of Default shall have occurred and be continuing; and

(v) the receipt by the Trustee of an Officer's Certificate stating that conditions (i), (ii), (iii) and (iv) above have been satisfied and setting forth (A) the number of Common Shares to be issued and delivered pursuant to the Holders Share Interest Payment Right, (B) the amount of interest payable on such Interest Payment Date, and (C) the Holders Share Interest Conversion Price used for calculating the number of Common Shares to be issued and delivered to Debentureholders pursuant to the Holders Share Interest Payment Right.

(f) In the event that the Debentureholder elects to convert the Debentures into Common Shares in accordance with Article 6, the Debentureholder may elect to receive accrued and unpaid interest on the principal amount of the Debentures payable in Common Shares rather than cash by providing the Holders Share Interest Election Notice to the Trustee at the same time as the Conversion Notice and other documents required to convert the Debentures into Conversion Shares pursuant to Article 6. All other terms of this Section 2.12 shall remain the same.

 - 45 -

(g) The Company will at all times use commercially reasonable best efforts to satisfy the foregoing conditions. If the foregoing conditions are not satisfied prior to the close of business on the Business Day immediately prior to the 10th Business Day from the Interest Payment Date, the Company shall pay the interest in accordance with Section 2.10 in cash.

(h) The Company will not issue fractional Common Shares pursuant to the Holders Share Interest Payment Right.

(i) A Debentureholder shall be treated as the holder of record of the Common Shares issued pursuant to the Holders Share Interest Payment Right effective immediately after the close of business on the Interest Payment Date and shall be entitled to all substitutions therefor, all income earned thereon or accretions thereto and all dividends or distributions (including dividends or distributions in kind) thereon and arising thereafter.

(j) Each certificate representing Common Shares issued in payment of accrued interest on Debentures shall bear the legend(s) as set forth in Section 2.13 and, if applicable, Section 2.14.

2.13 Canadian Legend

The certificates or other instruments representing the Debentures, and the certificates representing any Conversion Shares issued upon conversion of such Debentures (including any Common Shares issued for any interest payable on the Debentures), if issued prior to the expiration of the applicable hold period, will bear the following legend in accordance with Applicable Securities Legislation:

"UNLESS PERMITTED BY SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE JUNE 23, 2023."

and, in addition, certificates representing any Conversion Shares issued upon conversion of Debentures, if issued prior to the expiration of the applicable hold period, will bear the following legend in accordance with Applicable Securities Legislation:

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

 - 46 -

2.14 U.S. Legend

(a) The Debentures and the Conversion Shares issuable upon conversion thereof (including any Common Shares issued for any interest payable on the Debentures) have not been and will not be registered under the U.S. Securities Act or any state securities laws. To the extent that Debentures are issued to U.S. Purchasers, such Debentures and all Conversion Shares issuable on conversion thereof (together, the "Legended Securities") shall bear the following legend (the "U.S. Legend") until such time as the same is no longer required under applicable requirements of the U.S. Securities Act or state securities laws:

"THE SECURITIES REPRESENTED HEREBY [IN THE CASE OF DEBENTURES: AND THE SECURITIES ISSUABLE UPON CONVERSION HEREOF] HAVE NOT BEEN AND WILL NOT BE REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY LAWS OF ANY STATE OF THE UNITED STATES.

(THE "CORPORATION") THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (A) TO THE CORPORATION, (B) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE SECURITIES ACT AND IN COMPLIANCE WITH APPLICABLE LOCAL LAWS AND REGULATIONS, (C) IN COMPLIANCE WITH THE EXEMPTION FROM REGISTRATION UNDER THE U.S. SECURITIES ACT PROVIDED BY (1) RULE 144 THEREUNDER, IF AVAILABLE OR (2) RULE 144A THEREUNDER, IF AVAILABLE, AND IN BOTH CASES, IN COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS, OR (D) IN ANOTHER TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS, PROVIDED THAT IN THE CASE OF TRANSFERS PURSUANT TO (C)(1) OR (D) ABOVE, THE SELLER FURNISHES TO THE CORPORATION AN OPINION OF COUNSEL OF RECOGNIZED STANDING OR SUCH OTHER EVIDENCE IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE CORPORATION TO SUCH EFFECT. DELIVERY OF THIS CERTIFICATE MAY NOT CONSTITUTE "GOOD DELIVERY" IN SETTLEMENT OF TRANSACTIONS ON STOCK EXCHANGES IN CANADA."

provided, that if such Legended Securities are being transferred in compliance with the requirements of Rule 904 of Regulation S under the U.S. Securities Act and subject to the expiry of any hold or restricted period under Canadian securities laws, the above legend may be removed or such securities transferred to an unrestricted CUSIP by providing a declaration to the transfer agent for the applicable securities to the following effect (or as the Company may prescribe from time to time) (together with any other evidence required by the transfer agent for the applicable securities, which may, without limitation, include an opinion of counsel of recognized standing reasonably satisfactory to the Company, to the effect that such legend is no longer required under the applicable requirements of the U.S. Securities Act):

(the "Corporation") to which this declaration relates is being made in reliance on Rule 904 of Regulation S under the United States Securities Act of 1933, as amended (the "U.S. Securities Act"), and (b) certifies that (1) the undersigned is not an "affiliate" (as that term is defined in Rule 405 under the U.S. Securities Act) of the Corporation (other than an officer or director of the Corporation who is an affiliate solely by virtue of holding such position), (2) the offer of such securities was not made to a person in the United States and either (A) at the time the buy order was originated, the buyer was outside the United States, or the seller and any person acting on its behalf reasonably believed that the buyer was outside the United States, or (B) the transaction was executed in, on or through the facilities of a designated offshore securities market and neither the seller nor any person acting on its behalf knows that the transaction has been prearranged with a buyer in the United States, (3) neither the seller nor any affiliate of the seller nor any person acting on any of their behalf has engaged or will engage in any directed selling efforts in the United States in connection with the offer and sale of such securities, (4) the sale is bona fide and not for the purpose of "washing off" the resale restrictions imposed because the securities are "restricted securities" (as such term is defined in Rule 144(a)(3) under the U.S. Securities Act), (5) the seller does not intend to replace such securities with fungible unrestricted securities and (6) the contemplated sale is not a transaction, or part of a series of transactions which, although in technical compliance with Regulation S under the U.S. Securities Act, is part of a plan or scheme to evade the registration provisions of the U.S. Securities Act. Terms used herein have the meanings given to them by Regulation S under the U.S. Securities Act."

(b) The parties hereto hereby acknowledge and agree that the Legended Securities (which includes securities represented by a restricted CUSIP) may not be reoffered, or resold, pledged or otherwise transferred except: (i) to the Company; (ii) outside the United States in accordance with Rule 904 of Regulation S and in compliance with applicable local laws and regulations; (iii) in compliance with the exemption from registration under the U.S. Securities Act provided by (A) Rule 144 under the U.S. Securities Act, if available, or Rule 144A under the U.S. Securities Act, if available, and in each case in accordance with applicable state securities laws; or (iv) in another transaction that does not require registration under the U.S. Securities Act or any applicable state securities laws.

The transferee of a Debenture shall be entitled, after the appropriate form of transfer is lodged with the Trustee or other registrar and upon compliance with all other conditions in that behalf required by this Indenture or by law, to be entered on the register as the owner of such Debenture free from all equities or rights of set-off or counterclaim between the Company and the transferor or any previous holder of such Debenture, save in respect of equities of which the Company is required to take notice by statute or by order of a court of competent jurisdiction. Upon surrender for registration of transfer of Debentures, the Company shall issue and thereupon the Trustee shall Authenticate and deliver a new Debenture Certificate or confirm the electronic deposit of Uncertificated Debentures of like tenor in the name of the designated transferee and register such transfer in accordance with Section 3.1(b).

Notice of such transfer shall be given to the holders of such Debentures.

3.8 Charges for Registration, Transfer and Exchange

For each Debenture exchanged, registered, transferred or discharged from registration, the Trustee or other registrar, except as otherwise herein provided, may make a reasonable charge to the Company for its services and in addition may charge a reasonable sum for each new Debenture issued (such amounts to be agreed upon from time to time by the Trustee and the Company), and payment of such charges and reimbursement of the Trustee or other registrar for any stamp taxes or governmental or other charges required to be paid shall be made by the party requesting such exchange, registration, transfer or discharge from registration as a condition precedent thereto.

(b) The registered holder for the time being of any registered Debenture shall be entitled to the principal and/or the interest (if any) evidenced by such instruments, respectively, free from all equities or rights of setoff or counterclaim between the Company and the original or any intermediate holder thereof and all Persons may act accordingly and the receipt of any such registered holder for any such principal and/or the interest (if any) shall be a good discharge to the Trustee, any registrar and to the Company for the same and none shall be bound to inquire into the title of any such registered holder.

(c) Where Debentures are registered in more than one name, the principal and/or the interest (if any) from time to time payable in respect thereof may, upon the delivery of such reasonable requirements as the Trustee may prescribe, be paid to the order of any one of such holders, failing written instructions from them to the contrary, and the receipt of any one of such holders therefor shall be a valid discharge, to the Trustee, any registrar and to the Company.

Article 4
REDEMPTION AND PURCHASE OF DEBENTURES

4.1 Applicability of Article

In the event that the obligations in Section 5.2 have not been satisfied by the Company in full within 90 days following the Issue Date ("Redemption Trigger Date"), the Company shall be obligated to repurchase all outstanding Debentures in accordance with Section 4.4 (the "Automatic Redemption").

 - 52 -

4.2 Notice of Redemption

Notice of the Automatic Redemption shall be given to the holders of the Debentures with five Business Days following the Redemption Trigger Date, and such notice shall specify (i) the aggregate principal amount of Debentures subject to the Automatic Redemption, (ii) the date fixed for redemption which shall in any event not be later than the date that is 120 days following the Issue Date (the "Redemption Date"), and (iii) that the Debentures will be repurchased at a price equal to 100% of the principal amount of Debentures then outstanding plus accrued and unpaid interest thereon up to and including the Redemption Date (the "Redemption Price").

4.3 Deposit of Redemption Monies

The Automatic Redemption shall be provided for by the Company depositing with the Trustee or any paying agent to the order of the Trustee, on or before 11:00 a.m. (Toronto time) on the Business Day immediately prior to the Redemption Date specified in such notice, such sums of money as may be sufficient to pay the Redemption Price of the Debentures so called for redemption, plus accrued and unpaid interest thereon up to and including the Redemption Date, provided the Company may elect to satisfy this requirement by providing the Trustee with a certified cheque or wire transfer for such amounts required under this Section 4.3. The Company 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 the Automatic Redemption. Such deposit shall be irrevocable. From the sums so deposited, the Trustee shall pay or cause to be paid, to the holders of such Debentures so called for redemption, upon surrender of such Debentures, the principal and interest to which they are respectively entitled on the Automatic Redemption. Every such deposit shall be irrevocable.

4.4 Failure to Surrender Debentures

In case the holder of any Debenture so called for redemption shall fail on or before the Redemption Date to so surrender such holder's Debenture, or shall not within such time accept payment of the redemption monies payable, or give such receipt therefor, if any, as the Trustee may require, such redemption monies may be set aside in trust, 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 so set aside and, to that extent, the Debenture shall thereafter not be considered as outstanding hereunder and the Debentureholder shall have no other right except to receive payment out of the monies so paid and deposited, upon surrender and delivery of such holder's Debenture, plus any accrued but unpaid interest thereon to an including the Redemption Date. In the event that any money 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 Debentures issued hereunder shall remain so deposited for a period of four years from the Redemption Date, then such monies shall at the end of such period be paid over or delivered over by the Trustee or such depository or paying agent to the Company on its demand, and thereupon the Trustee shall not be responsible to Debentureholders for any amounts owing to them and, subject to applicable law, thereafter the holder of a Debenture in respect of which such money was so repaid to the Company shall have no rights in respect thereof except to obtain payment of the money due from the Company, subject to any limitation period provided by the laws of Ontario.

All Debentures so purchased will be delivered to the Trustee and shall be cancelled and no Debentures shall be issued in substitution therefor.

(b) If, upon an invitation for tenders, more Debentures are tendered at the same lowest price than the Company is prepared to accept, the Debentures to be purchased by the Company shall be selected by the Trustee on a pro rata basis from the Debentures tendered by each tendering Debentureholder who tendered at such lowest price. For this purpose the Trustee may make, and from time to time amend, regulations with respect to the manner in which Debentures may be so selected, and regulations so made shall be valid and binding upon all Debentureholders, notwithstanding the fact that as a result thereof one or more of such Debentures become subject to purchase in part only. The holder of a Debenture of which a part only is purchased, upon surrender of such Debenture for payment, shall be entitled to receive, without expense to such holder, one or more new Debentures for the unpurchased part so surrendered, and the Trustee shall Authenticate and deliver such new Debenture or Debentures upon receipt of the Debenture so surrendered or, with respect to an Uncertificated Debenture, the Depository shall electronically deposit the unpurchased part so surrendered.

The Company shall, at the Company's expense, ensure that the Security Documents and all documents, caveats, security notices, financing statements and financing change statements in respect thereof, are promptly filed and re-filed and registered as often as may be required by applicable law or as may be necessary or desirable to perfect and preserve the Security Interests created by the Security Documents and to ensure that such Security Interests are first ranking, subject only to Permitted Encumbrances, and will promptly provide the Collateral Agent and the Trustee with evidence (satisfactory to the Collateral Agent and the Trustee) of such filing, registration and deposit after the making thereof. The Company shall, if and when requested to do so by the Trustee or the Collateral Agent, furnish to the Trustee and the Collateral Agent an opinion of Counsel to establish compliance with the provisions of this Section 5.2.

5.4 Permitted Activities

Until an Event of Default has occurred, each of the Guarantor and the Limited Recourse Guarantor, without the consent of the Trustee, shall be entitled:

(a) to exercise all voting and/or consensual powers pertaining to the Secured Assets for all purposes not inconsistent with the terms of this Indenture, except that the Guarantor or Limited Recourse Guarantor, as applicable. shall not have any right to exercise any such power if the voting action or omission to act in favour of which the Company intends to exercise such power would impair the Security Interests or violate the provisions of this Indenture;

 - 55 -

(b) to exercise and receive the benefit of all other rights associated with the Security Interests, including the right receive and retain any and all cash dividends, distributions, payments and entitlements on the Secured Assets;

(e) to sell, assign, transfer, abandon, surrender or otherwise dispose of free of the Security Interest constituted by the Security Documents any fixtures, equipment, machinery, tools, implements, apparatus, facilities or appliances, which have become worn out, unserviceable, obsolete, unsuitable or unnecessary in the conduct of its business or in the operation of any of the Secured Assets provided that there shall have been or shall be substituted for the same other fixtures, equipment, machinery, tools, implements, apparatus, facilities or appliances not necessarily of the same character but at least of equal utility at the date of such substitution or replacement (which forthwith shall become subject to the Security Interest of the Security Documents) of and to the extent that such replacement or substitution is necessary or desirable for the proper and efficient conduct of the business of the Company (as applicable) or in the operation of the Secured Assets,

and the Collateral Agent will, at the expense of the Company, execute and deliver from time to time releases and discharges necessary or required as advised by Counsel with respect to the foregoing subsections. Except as specifically permitted above, the Company, the Guarantor and the Limited Recourse Guarantor, respectively, will not dispose of any of their respective property and assets comprising or forming part of the Secured Assets to any Person. Notwithstanding any of the foregoing, nothing herein shall be deemed to permit the sale, transfer, disposition or sale-leaseback of all or any portion of the Project.

5.5 Further Assurances

The Company hereby covenants and agrees that it will at all times do, execute, acknowledge and deliver or cause to be done, executed, acknowledged and delivered all such further acts, deeds, transfers, assignments and assurances as the Trustee or the Collateral Agent may reasonably require for the better accomplishing and effectuating the purpose of this Indenture, including the execution and delivery of indentures supplemental hereto more particularly describing the Secured Assets or to correct or amplify the description of the Secured Assets or to better assure, convey and confirm unto the Collateral Agent any of the Secured Assets. Upon the execution of any supplemental indenture under this Section, this Indenture shall be modified in accordance therewith, and each such supplemental indenture shall form part of this Indenture for all purposes.

Should the Collateral Agent, as advised by counsel, determine at any time and from time to time that the form and nature of any of the then existing Security Document is deficient in any way or does not fully provide the Collateral Agent (for itself and the Debentureholders) with the Security and priority to which it is entitled hereunder and provides written notice of such determination to the Company, the Company will within a reasonable period of time (not to exceed 60 days from receipt of such notice and amendments or new Security Documents, as applicable) execute and deliver or cause to be executed and delivered to the Collateral Agent, at the Company's expense, such amendments to the Security Documents or provide such new Security Documents as the Collateral Agent may reasonably request.

 - 56 -

5.7 Delivery of an Opinion to the Trustee and Collateral Agent

The Company will furnish to the Trustee, the Collateral Agent, the Agents and their counsel at the time of execution and delivery of this Indenture, an opinion of Counsel in form and substance customary for financings of this nature as determined by the Trustee, acting reasonably, relying on Counsel, including, without limitation, opinions substantially to the effect that subject to customary qualifications:

(a) each Security Document and Transaction Guarantee constitutes a valid and binding obligation of the Group Member party thereto, enforceable against such party in accordance with its terms;

(b) each Security Document creates a valid security interest in favour of the Collateral Agent, for the benefit of the Collateral Agent, the Trustee and the Debentureholders, in the personal property described therein in which the applicable Group Member, as the case may be, that is a party thereto now has rights, and is sufficient to create a valid security interest in favour of the Collateral Agent, for the benefit of the Collateral Agent and the Debentureholders, in any personal property described therein in which such Group Member is a party thereto hereafter acquires rights when those rights are acquired by such party, in each case to secure payment and performance of the obligations described therein as being secured thereby;

(c) registration has been made in all public offices provided for under the laws of Nevada or Delaware where such registration is necessary or desirable to preserve, protect or perfect the security interests created by each Security Document in favour of the Collateral Agent, for the benefit of the Collateral Agent, the Trustee and the Debentureholders. Except as otherwise expressly stated herein, no rerecordings, renewals, reregistrations or refilings are necessary to maintain the effect of such registrations; and

(d) no authorization, consent, permit or approval of, or other action by, or filing with or notice to, any governmental or regulatory authority or agency is required in connection with the execution, delivery and performance by a Group Member of any Security Document or Transaction Guarantee to which it is a party, other than such filings necessary to perfect the Security Interests.

 - 57 -

5.8 Discharge

Subject to the provisions of Article 9, upon the full and final payment and performance of the obligations under the Debentures and this Indenture and the rights hereby granted shall, at the request of the Company, be terminated and thereupon the Collateral Agent shall at the request and at the expense of the Company cancel and discharge the Security Interests and execute and deliver to the Company, the Guarantor or the Limited Recourse Guarantor, such deeds and other instruments as shall be requisite to cancel and discharge the Security Interests. Further, this Indenture shall continue to be effective or be reinstated, as the case may be, if for any reason at any time any payment or performance of the obligations under the Debentures and this Indenture, or any part thereof, is rescinded, reversed, nullified, rendered void or voidable or such payment must otherwise be restored, refunded, returned or reimbursed by the Collateral Agent or a Debentureholder.

Article 6
CONVERSION OF DEBENTURES

6.1 Applicability of Article

(a) Any Debentures issued hereunder will be convertible into Conversion Shares at the Conversion Price in accordance with such other provisions as shall have been determined at the time of issue of such Debentures and shall have been expressed in this Indenture (including subsection 2.1(f) and Section 3.7 hereof), in such Debentures, in an Officer's Certificate, or in a supplemental indenture authorizing or providing for the issue thereof.

(b) Such right of conversion shall extend only to the maximum number of whole Conversion Shares into which the aggregate principal amount of the Debenture or Debentures surrendered for conversion at any one time by the holder thereof may be converted. Fractional interests in Conversion Shares shall be adjusted for in the manner provided in Subsection 6.1(c).

(c) The Company shall not be required to issue fractional Conversion Shares upon the conversion of Debentures into Conversion Shares pursuant to this Article 6. Fractional Conversion Shares will be rounded down to the nearest whole Conversion Share without the payment of any compensation to the holder. If more than one Debenture shall be surrendered for conversion at one time by the same holder, the number of whole Conversion Shares issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of such Debentures to be converted.

(d) The Company 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 Conversion Shares as shall then be issuable upon the conversion of all outstanding Debentures. The Company covenants with the Trustee that all Conversion Shares which shall be so issuable shall be duly and validly issued as fully-paid and non-assessable.

 - 58 -

6.2 Notice of Expiry of Conversion Privilege

Notice of the expiry of the conversion privileges of the Debentures shall be given by or on behalf of the Company, not more than 60 days and not less than 30 days prior to the Maturity Date, in the manner provided in Section 13.2.

6.3 Revival of Right to Convert

If the payment of the purchase price of any Debenture which has been tendered in acceptance of an offer to purchase by the Company pursuant to Section 2.1(h) is not made on the date on which such purchase is required to be made, as the case may be, then, provided the Time of Expiry has not passed, the right to convert such Debentures shall revive and continue as if such Debenture had not been called for redemption or tendered in acceptance of the Company's offer, respectively.

6.4 Manner of Exercise of Right to Convert

(a) The holder of a Debenture desiring to convert such Debenture in whole or in part into Conversion Shares shall surrender such Debenture to the Trustee at its principal office in the City of Toronto, Ontario together with the conversion notice in the form of Schedule "C" or any other written notice in a form satisfactory to the Trustee, duly executed by the holder or his executors or administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Trustee, exercising his right to convert such Debenture in accordance with the provisions of this Article; provided that with respect to an Uncertificated Debenture, registration and surrender of interests in the Debentures will be made only through the Depository's non-certificated system. Thereupon such Debentureholder or, subject to payment of all applicable stamp or security transfer taxes or other governmental charges and compliance with all reasonable requirements of the Trustee, his nominee(s) or assignee(s) shall be entitled to be entered in the books of the Company as at the Date of Conversion (or such later date as is specified in subsection 6.4(g)) as the holder of the number of Conversion Shares into which such Debenture is convertible in accordance with the provisions of this Article and, as soon as practicable thereafter, the Company shall deliver to such Debentureholder or, subject as aforesaid, his nominee(s) or assignee(s), a certificate or certificates for such Conversion Shares or deposit such Conversion Shares through the Depository's non-certificated system and make or cause to be made any payment of interest to which such holder is entitled in accordance with subsection 6.4(j).

(b) A Beneficial Holder may exercise the right evidenced by a Debenture to receive Conversion Shares by causing a Participant to deliver to the Depository on behalf of the Beneficial Holder, a notice of such Beneficial Xxxxxx's intention to convert the Debentures in a manner acceptable to the Depository. Forthwith upon receipt by the Depository of such notice, the Depository shall deliver to the Trustee a Transaction Instruction confirming its intention to convert Debentures in a manner acceptable to the Trustee, including by electronic means through the non- certificated inventory system.

 - 59 -

(c) A notice in form acceptable to the Participant from such Beneficial Holder should be provided to the Participant sufficiently in advance so as to permit the Participant to deliver notice to the Depository and for the Depository in turn to deliver notice to the Trustee prior to the Time of Expiry. The Depository will initiate the exercise by way of the Transaction Instruction and the Trustee will execute the exercise by issuing to the Depository through the non-certificated inventory system the Conversion Shares to which the exercising Debentureholder is entitled pursuant to the conversion.

(d) By causing a Participant to deliver notice to the Depository, a Debentureholder shall be deemed to have irrevocably surrendered his or her Debentures so exercised and appointed such Participant to act as his or her exclusive settlement agent with respect to the conversion and the receipt of the Conversion Shares in connection with the obligations arising from such conversion.

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

(f) Any Transaction Instruction referred to in this Section 6.4 shall be signed by the registered Debentureholder, or its executors or administrators or other legal representatives or an attorney of the registered Debentureholder, duly appointed by an instrument in writing satisfactory to the Trustee but such exercise form need not be executed by the Depository.

(g) For the purposes of this Article, subject to Section 3.7, 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(a); 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 Conversion Shares shall become the holder or holders of record of such Conversion Shares as at the date on which such register is next reopened.

 - 60 -

(h) Any part, being $1,000 or an integral multiple thereof, of a Debenture in a denomination in excess of $1,000 or an integral multiple thereof 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.

(i) The holder of any Debenture of which only a part is converted shall, upon the exercise of his right of conversion surrender such Debenture to the Trustee in accordance with subsection 6.4(a), and the Trustee shall cancel the same and shall without charge to the Debentureholder forthwith Authenticate and deliver to the holder a new Debenture or Debentures in an aggregate principal amount equal to the unconverted part of the principal amount of the Debenture so surrendered or, with respect to an Uncertificated Debenture, registration and surrender of interests in the Debentures will be made only through the Depository's non-certificated system.

(j) The holder of a Debenture surrendered for conversion in accordance with this Section 6.4 shall be entitled to receive accrued and unpaid interest in respect thereof, in cash, up to but excluding the Date of Conversion, and the Conversion Shares issued upon such conversion shall rank only in respect of distributions or dividends declared in favour of shareholders of record on and after the Date of Conversion or such later date as such holder shall become the holder of record of such Conversion Shares pursuant to subsection 6.4(g), from which applicable date they will for all purposes be and be deemed to be issued and outstanding as fully paid and non-assessable Common Shares.

(k) Any portion of the Debentures that cannot be converted as a result of regulatory restrictions or as a result of the Company being unable to obtain any necessary shareholder approvals and that has not been prepaid shall be due and payable in cash on the Maturity Date.

6.5 Adjustment of Conversion Price

Subject to the requirements of the Stock Exchange, 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 during the Adjustment Period, the Company shall:

(i) fix a record date for the issue of, or issue, Common Shares to the holders of all or substantially all of the outstanding Common Shares by way of a stock dividend or otherwise;

(ii) fix a record date for the distribution to, or make a distribution to, the holders of all or substantially all of the outstanding Common Shares payable in Common Shares or securities exchangeable or exercisable for or convertible into Common Shares;

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

 - 61 -

(iv) reduce, combine or consolidate its then outstanding Common Shares into a lesser number of Common Shares,

(any of such events in Sections 6.5(a)(i), 6.5(a)(ii), 6.5(a)(iii) and 6.5(a)(iv) above being herein called a "Common Share Reorganization"), then the Conversion Price shall be adjusted on the earlier of the record date on which holders of Common Shares are determined for the purposes of the Common Share Reorganization and the effective date of the Common Share Reorganization to the amount determined by multiplying the Conversion Price in effect immediately prior to such record date or effective date, as the case may be, by a fraction:

(i) the numerator of which shall be the number of Common Shares outstanding on such record date or effective date, as the case may be, before giving effect to such Common Share Reorganization; and

(ii) the denominator of which shall be the number of Common Shares which will be outstanding immediately after giving effect to such Common Share Reorganization (including in the case of a distribution of securities exchangeable or exercisable for or convertible into Common Shares, the number of Common Shares that would have been outstanding had such securities been exchanged or exercised for or converted into Common Shares on such date).

To the extent that any adjustment in the Conversion Price occurs pursuant to this Section 6.5(a) as a result of the fixing by the Company of a record date for the distribution of securities exchangeable or exercisable for or convertible into Common Shares, the Conversion Price shall be readjusted immediately after the expiry of any relevant exchange, exercise or conversion right to the Conversion Price which would then be in effect based upon the number of Common Shares actually issued and remaining issuable after such expiry and shall be further readjusted in such manner upon the expiry of any further such right.

(b) If at any time during the Adjustment Period, the Company shall fix a record date for the issue or distribution to the holders of all or substantially all of the outstanding Common Shares of rights, options or warrants pursuant to which such holders are entitled, during a period expiring not more than 45 days after the record date for such issue (such period being the "Rights Period"), to subscribe for or purchase Common Shares or securities exchangeable or exercisable for or convertible into Common Shares at a price per share to the holder (or in the case of securities exchangeable or exercisable for or convertible into Common Shares, at an exchange, exercise or conversion price per share) at the date of issue of such securities of less than 95% of the Current Market Price of the Common Shares on such record date (any of such events being called a "Rights Offering"), the Conversion Price shall be adjusted effective immediately after the record date for such Rights Offering to the amount determined by multiplying the Conversion Price in effect on such record date by a fraction:

 - 62 -

(i) the numerator of which shall be the aggregate of

(1) the number of Common Shares outstanding on the record date for the Rights Offering, and

(2) the quotient determined by dividing

(A) either (a) the product of the number of Common Shares offered during the Rights Period pursuant to the Rights Offering and the price at which such Common Shares are offered, or, (b) the product of the exchange, exercise or conversion price of the securities so offered and the number of Common Shares for or into which the securities offered pursuant to the Rights Offering may be exchanged, exercised or converted, as the case may be, by

(B) the Current Market Price of the Common Shares as of the record date for the Rights Offering; and

(ii) the denominator of which shall be the aggregate of the number of Common Shares outstanding on such record date and the number of Common Shares offered pursuant to the Rights Offering (including in the case of the issue or distribution of securities exchangeable or exercisable for or convertible into Common Shares the number of Common Shares for or into which such securities may be exchanged, exercised or converted).

If by the terms of the rights, options, or warrants referred to in this Section 6.5(b), there is more than one purchase, exchange, exercise or conversion price per Common Share, the aggregate price of the total number of additional Common Shares offered for subscription or purchase, or the aggregate exchange, exercise or conversion price of the exchangeable, exercisable or convertible securities so offered, shall be calculated for purposes of the adjustment on the basis of the lowest purchase, exchange, exercise or conversion price per Common Share, as the case may be. Any Common Shares owned by or held for the account of the Company shall be deemed not to be outstanding for the purpose of any such calculation. To the extent that any adjustment in the Conversion Price occurs pursuant to this Section 6.5(b) as a result of the fixing by the Company of a record date for the issue or distribution of rights, options or warrants referred to in this Section 6.5(b), the Conversion Price shall be readjusted immediately after the expiry of any relevant exchange, exercise or conversion right to the Conversion Price which would then be in effect based upon the number of Common Shares actually issued and remaining issuable after such expiry and shall be further readjusted in such manner upon the expiry of any further such right. To the extent that such Rights Offering is not ultimately so made, the Conversion Price shall then be readjusted to the Conversion Price which would then be in effect if such record date had not been fixed.

 - 63 -

(c) If at any time during the Adjustment Period the Company shall fix a record date for the issue or distribution to the holders of all or substantially all of the outstanding Common Shares of:

(i) shares of the Company of any class other than Common Shares;

(ii) rights, options or warrants to acquire Common Shares or securities exchangeable or exercisable for or convertible into Common Shares (other than rights, options or warrants pursuant to which holders of Common Shares are entitled, during a period expiring not more than 45 days after the record date for such issue, to subscribe for or purchase Common Shares or securities exchangeable or exercisable for or convertible into Common Shares at a price per share (or in the case of securities exchangeable or exercisable for or convertible into Common Shares at an exchange, exercise or conversion price per share) on the record date for the issue of such securities to the holder of at least 95% of the Current Market Price of the Common Shares on such record date);

(iii) evidences of indebtedness of the Company; or

(iv) any property or other assets of the Company;

and if such issue or distribution does not constitute a Common Share Reorganization or a Rights Offering (any of such non-excluded events being herein called a "Special Distribution"), the Conversion Price shall be adjusted effective immediately after the record date for the Special Distribution to the amount determined by multiplying the Conversion Price by a fraction:

(1) the numerator of which shall be the difference between

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

(B) the fair value, as determined by the directors of the Company and subject to approval by the applicable Stock Exchanges, to the holders of Common Shares of the shares, rights, options, warrants, evidences of indebtedness or property or assets to be issued or distributed in the Special Distribution, and

(2) the denominator of which shall be the product obtained by multiplying the number of Common Shares outstanding on such record date by the Current Market Price of the Common Shares on such record date.

Any Common Shares owned by or held for the account of the Company shall be deemed not to be outstanding for the purpose of such calculation. To the extent that any adjustment in the Conversion Price occurs pursuant to this Section 6.5(c) as a result of the fixing by the Company of a record date for the issue or distribution of rights, options or warrants to acquire Common Shares or securities exchangeable or exercisable for or convertible into Common Shares referred to in this Section 6.5(c), the Conversion Price shall be readjusted immediately after the expiry of any relevant exchange, exercise or conversion right to the amount which would then be in effect based upon the number of Common Shares issued and remaining issuable after such expiry and shall be further readjusted in such manner upon the expiry of any further such right.

 - 64 -

(d) If at any time during the Adjustment Period there shall occur:

(i) a reclassification or redesignation of the Common Shares, a change of the Common Shares into other shares or securities or any other capital reorganization involving the Common Shares other than a Common Share Reorganization;

(ii) a consolidation, amalgamation, arrangement or merger of the Company with or into another body corporate which results in a reclassification or redesignation of the Common Shares or a change of the Common Shares into other shares or securities; or

(iii) the transfer of the undertaking or assets of the Company as an entirety or substantially as an entirety to another corporation or entity;

(any of such events being called a "Capital Reorganization"), after the effective date of the Capital Reorganization the Debentureholder shall be entitled to receive, and shall accept, for the same aggregate consideration, upon the conversion of the Debentures, in lieu of the number of Conversion Shares to which the Debentureholder was theretofore entitled upon the conversion of the Debentures, the kind and aggregate number of shares and other securities or property resulting from the Capital Reorganization which the Debentureholder would have been entitled to receive as a result of the Capital Reorganization if, on the effective date thereof, the Debentureholder had been the registered holder of the number of Conversion Shares which the Debentureholders was theretofore entitled to purchase or receive upon the conversion of the Debentures. If necessary, as a result of any such Capital Reorganization, appropriate adjustments shall be made in the application of the provisions of this Indenture with respect to the rights and interests thereafter of the Debentureholder to the end that the provisions shall thereafter correspondingly be made applicable as nearly as may reasonably be possible in relation to any shares or other securities or property thereafter deliverable upon the conversion of the Debentures.

(e) If at any time during the Adjustment Period the Company 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 (other than dividends paid in the ordinary course, once initiated under a dividend policy approved by the board of directors), 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:

 - 65 -

(i) the numerator of which shall be the difference between

(1) the Current Market Price on such record date, and

(2) the amount in cash per Common Share distributed to holders of Common Shares, and

(ii) the denominator of which shall be the Current Market Price on such record date.

Such adjustment shall be subject to the approval of the TSX and 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.

6.6 Rules Regarding Calculation of Adjustment

For the purposes of Article 6:

(a) Subject to this Section 6.6, any adjustment made pursuant to Section 6.5 hereof shall be made successively whenever an event referred to therein shall occur.

(b) If more than one subsection of Section 6.5 is applicable to a single event, the subsection shall be applied that produces the adjustment most favourable to Debentureholders and no single event shall cause an adjustment under more than one subsection of Section 6.5 so as to result in duplication;

(c) No adjustment in the Conversion Price shall be required unless such adjustment would result in a change of at least one per cent in the Conversion Price and no adjustment shall be made in the number of Conversion Shares obtainable upon the conversion of the Debentures unless it would result in a change of at least one one- hundredth of a Conversion Share; provided, however, that any adjustments which except for the provision of this Section 6.6(c) would otherwise have been required to be made shall be carried forward and taken into account in any subsequent adjustment. Notwithstanding any other provision of Section 6.6 hereof, no adjustment pursuant to Section 6.5 shall be made which would result in an increase in the Conversion Price or a decrease in the number of Conversion Shares issuable upon the conversion of the Debentures (except in respect of the Common Share Reorganization described in Section 6.5(a) hereof or a Capital Reorganization described in Section 6.5(d)(ii) hereof).

(d) Subject to the Company receiving approval from the TSX or other applicable Stock Exchange, no adjustment in the Conversion Price or in the number or kind of securities obtainable upon the conversion of the Debentures shall be made in respect of any event described in Section 6.5 hereof if the Debentureholder is entitled to participate in such event on the same terms mutatis mutandis as if the Debentureholder had converted the Debentures prior to or on the record date or effective date, as the case may be, of such event.

 - 66 -

(e) No adjustment in the Conversion Price or in the number of Conversion Shares obtainable upon the conversion of the Debentures shall be made pursuant to Section 6.5 hereof in respect of (i) the issue from time to time of Conversion Shares pursuant to this Indenture or (ii) the issue from time to time of Common Shares pursuant to any stock option, stock purchase or stock bonus plan in effect from time to time for directors, officers or employees of the Company and/or any Subsidiary of the Company, and any such event shall not be deemed to be a Common Share Reorganization, a Rights Offering nor any other event described in Section 6.5 hereof.

(f) Subject to the Company receiving approval from the TSX or other applicable Stock Exchange, if at any time during the Adjustment Period the Company shall take any action affecting the Common Shares, other than an action or event described in Section 6.5 hereof, which in the opinion of the directors of the Company would have a material adverse effect upon the rights of Debentureholders, either the Conversion Price or the number of Conversion Shares obtainable upon conversion of the Debentures shall be adjusted in such manner and at such time by action by the directors of the Company, in their sole discretion, as may be equitable in the circumstances. Failure of the taking of action by the directors of the Company so as to provide for an adjustment prior to the effective date of any action by the Company affecting the Common Shares shall be deemed to be conclusive evidence that the directors of the Company have determined that it is equitable to make no adjustment in the circumstances.

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

(h) In any case in which this Indenture shall require that an adjustment shall become effective immediately after a record date for an event referred to in Section 6.5 hereof, the Company may defer, until the occurrence of such event:

(i) issuing to the Debentureholder, to the extent that the Debentures are converted after such record date and before the occurrence of such event, the additional Conversion Shares or other securities issuable upon such conversion by reason of the adjustment required by such event; and

 - 67 -

(ii) delivering to the Debentureholder any distribution declared with respect to such additional Conversion Shares or other securities after such record date and before such event;

provided, however, that the Company shall deliver to the Debentureholder an appropriate instrument evidencing the right of the Debentureholder upon the occurrence of the event requiring the adjustment, to an adjustment in the Conversion Price.

(i) In the absence of a resolution of the directors of the Company fixing a record date for a Rights Offering, the Company shall be deemed to have fixed as the record date therefor the date of the issue of the rights, options or warrants issued pursuant to the Rights Offering.

(j) If a dispute shall at any time arise with respect to adjustments of the Conversion Price or the number of Conversion Shares obtainable upon the conversion of the Debentures, such disputes shall be conclusively determined by the Auditors of the Company or if they are unable or unwilling to act, by such other firm of independent chartered accountants as may be selected by the directors of the Company and any such determination shall be conclusive evidence of the correctness of any adjustment made pursuant to Section 6.5 hereof and shall be binding upon the Company, Trustee and the Debentureholders.

(k) As a condition precedent to the taking of any action which would require an adjustment pursuant to Section 6.5 hereof, including the Conversion Price and the number of Conversion Shares or other securities which are to be received upon the conversion of Debentures, the Company shall take any action which may, in the opinion of Counsel to the Company, be necessary in order that the Company may validly and legally issue as fully paid and non-assessable shares all of the Conversion Shares or other securities which the Debentureholder is entitled to receive in accordance with the provisions of this Indenture.

(l) If the Company shall take any action affecting the Common Shares and the holders thereof, and, in the opinion of the directors of the Company acting reasonably, the adjustment provisions of Section 6.5 are not strictly applicable or, if strictly applicable, would not fairly protect the rights of the holder or the Company in accordance with the intent and purpose of Section 6.5, the provisions of Section 6.5 shall be adjusted in such manner, if any, and at such time, by action by the directors of the Company which the directors of the Company, in their discretion, may reasonably determine to be equitable in the circumstances but subject in all cases to any necessary regulatory approval, including approval of the TSX (or such other stock exchange or quotation system on which the Common Shares are then listed and posted (or quoted) for trading, as applicable). Failure of the taking of action by the directors of the Company so as to provide for an adjustment on or prior to the effective date of any action by the Company affecting the Common Shares will be conclusive evidence that the board of directors of the Company has determined that it is equitable to make no adjustment in the circumstances.

 - 68 -

6.9 Protection of Trustee

The Trustee shall not:

(b) If the Company 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 Company shall deduct and withhold such Withholding Taxes from any payment to be made or with respect to the Debentures as and when required by applicable law, and, provided that the Company 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 Company's obligations under the Debentures.

(c) Notwithstanding anything to the contrary contained in this Indenture, if the Company is 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 to a holder, if such Withholding Taxes are an Indemnified Tax, the Company will pay to such holder as additional interest such additional amounts ("Additional Amounts") as may be necessary so that the net amount received by each such holder after such withholding or deduction (and after deducting any Withholding Taxes on such Additional Amounts) will not be less than the amount the holder would have received if such Withholding Taxes had not been withheld or deducted.

(d) 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 Company 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. The Company shall provide the Trustee with copies of receipts or other communications relating to the remittance of such withheld amount or the filing of any forms received from such Governmental Authority or agency promptly after receipt thereof.

 - 85 -

(e) The Company will indemnify and hold harmless each holder, and, within ten Business Days upon a written request in respect thereof, reimburse each such holder for the amount, excluding any payment of Additional Amounts by the Company, of (a) any Withholding Taxes so levied or imposed and paid by such holder as a result of payments made under or with respect to the Debentures; (b) any liability (including penalties, interest and expenses) arising therefrom or with respect thereto; and (c) any Withholding Taxes imposed with respect to any reimbursement under clause (a) or (b), provided such amounts referred to in (a) to (c) are not Connection Income Taxes, and such indemnity will survive the termination or discharge of this Indenture and the payment of all amounts under or with respect to the Debenture indefinitely.

(f) If the Company reasonably believes that such Taxes were not correctly or legally asserted, the Debentureholder will use reasonable efforts to cooperate with the Company to obtain a refund of such Taxes, so long as such efforts would not, in the sole determination of the Debentureholder, result in any additional out-of-pocket costs or expenses not reimbursed by the Company or be otherwise materially disadvantageous to the Debentureholder.

(g) Any Debentureholder that is entitled to an exemption from or reduction of withholding Tax with respect to payments made hereunder shall deliver to the Company, at the time or times reasonably requested by the Company, such properly completed and executed documentation reasonably requested by the Company as will permit such payments to be made without withholding or at a reduced rate of withholding.

(h) If a Debentureholder determines, in its sole discretion exercised in good faith, that it has received a refund of any Indemnified Taxes as to which it has been indemnified by the Company pursuant to this Section 8.14 (including by payment of Additional Amounts pursuant to this Section 8.14), it shall pay over to the Company an amount equal to such refund (but only to the extent of indemnity payments made, or Additional Amounts paid, by the Company under this Section 8.14 with respect to Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such Debentureholder and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). The Company, upon the request of a Debentureholder, shall repay to that Debentureholder the amount paid over to the Company pursuant to this Section 8.14(h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event such Debentureholder is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 8.14(h), in no event shall the Debentureholder be required to pay an amount to the Company pursuant to this Section 8.14(h) the payment of which would place the Debentureholder in a less favorable net after-Tax position than the Debentureholder would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This Section 8.14(h) shall not be construed to require any Debentureholder to make available its Tax Returns (or any other information relating to its taxes which it deems confidential) to the Company or any other person.

 - 86 -

(i) Wherever in this Indenture there is mentioned, in any context, the payment of principal (and premium, if any), interest or any other amount payable under or with respect to a Debenture, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

(ii) 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.

(b) No such act or omission either of the Trustee or of the Debentureholders shall extend to or be taken in any manner whatsoever to affect any subsequent Event of Default or the rights resulting therefrom.

9.4 Enforcement by the Trustee or Collateral Agent

(b) 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 Company 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, which may include acting and relying on Counsel, in order to have the respective claims of the Trustee and of the holders of the Debentures against the Company 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 9.3, 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.

 - 92 -

(c) 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.

(d) 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. 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.

 - 94 -

(iv) fourth, in payment of the surplus, if any, of such monies to the Company or its assigns;

provided, however, that no payment shall be made pursuant to clause (iii) above in respect of the principal and/or the interest on any Debenture held, directly or indirectly, by or for the benefit of the Company or any Subsidiary (other than any Debenture pledged for value and in good faith to a Person other than the Company or any Subsidiary but only to the extent of such Person's interest therein) except subject to the prior payment in full of the principal and interest on all Debentures which are not so held.

(b) 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 9.1(a)(i), 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 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 foregoing shall, however, not apply to a final payment in distribution hereunder.

 - 95 -

9.9 Remedies Cumulative

No remedy herein conferred upon or reserved to the Trustee, or upon or to the holders of Debentures is intended to be exclusive of any other remedy, but each and every such remedy shall be cumulative and shall be in addition to every other remedy given hereunder or now existing or hereafter to exist by law or by statute.

(b) The Company's right to exercise the Common Share Interest Payment Election shall be conditional upon the following conditions being met on or before 11:00 a.m. (Toronto time) on the day which is one Business Day prior to the Interest Payment Date, such conditions being in favour of the Debentureholders:

(i) the issuance of the Common Shares on the exercise of the Common Share Interest Payment Election shall be made in accordance with Applicable Securities Legislation;

If the foregoing conditions are not satisfied on or before 11:00 a.m. (Toronto time) on the Business Day prior to the Interest Payment Date, the Company shall pay the interest payable on the Debentures on such Interest Payment Date for which a Common Share Interest Payment Election was made in accordance with Section 2.10, unless the Debentureholders waive the conditions which are not satisfied by way of Extraordinary Resolution.

(c) In the event that the Company duly exercises its Common Share Interest Payment Election, the Company shall on or before 11:00 a.m. (Toronto time) on the Business Day immediately prior to the Interest Payment Date, deliver to the Trustee, for delivery to and on account of the registered holders of such Debentures appearing on the registers maintained by the Trustee at the close of business on the fifth Business Day prior to the applicable Interest Payment Date, the Common Shares to which such holders are entitled. The Company 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 the Common Share Interest Payment Election. Every such deposit shall be irrevocable.

(d) From the certificates so deposited, the Trustee shall deliver to such Debentureholders the certificates to which they are entitled.

(e) No fractional Common Shares shall be delivered upon the exercise of the Common Share Interest Payment Election but, in lieu thereof, the Company shall pay to the Trustee for the account of the entitled Debentureholders, at the time contemplated in Section 11.1(c), the cash equivalent thereof determined on the basis of the Conversion Price as of the Business Day prior to the Interest Payment Date (less applicable withholding tax, if any), provided, however, the Company shall not be required to make any payment of less than $10.00.

(f) A holder shall be treated as the shareholder of record of the Common Shares issued on due exercise by the Company of its Common Share Interest Payment Election effective immediately after the close of business on the Interest Payment Date, and shall be entitled to all substitutions therefore, all income earned thereon or accretions thereto and all dividends or distributions (including dividends and dividends or distributions in kind) thereon and arising thereafter, and in the event that the Trustee receives the same, it shall hold the same in trust for the benefit of such holder.

 - 101 -

(g) The Company shall at all times reserve and keep available out of its authorized Common Shares, solely for the purpose of issue and delivery upon the exercise of the Common Share Interest Payment Election as provided herein, and shall issue to Debentureholders to whom Common Shares will be issued pursuant to exercise of the Common Share Interest Payment Election, such number of Common Shares as shall be issuable in such event. All Common Shares which shall be so issuable shall be duly and validly issued as fully paid and non-assessable.

(h) The Company shall from time to time promptly pay, or make provision satisfactory to the Trustee for the payment of, all taxes and charges which may be imposed by the laws of Canada or any province thereof (except income tax, withholding tax or security transfer tax, if any) which shall be payable with respect to the issuance or delivery of Common Shares to holders upon exercise of the Common Share Interest Payment Election pursuant to the terms of the Debentures and of this Indenture.

(i) If the Company makes a Common Share Interest Payment Election in accordance with this Section 11.1 and if the payment represented by the Common Shares issuable in satisfaction of the Interest Obligation is subject to withholding taxes and the amount of the cash payment, if any, of the principal amount due on maturity, if such maturity is concurrent with the interest payment, is insufficient to satisfy such withholding taxes, the Trustee, on the written direction of the Company but for the account of the holder: (a) shall sell, or cause to be sold, through the investment banks, brokers or dealers selected by the Company, out of the Common Shares issued by the Company for this purpose, such number of Common Shares that, together with any cash component of the principal amount due on maturity, if such maturity is concurrent to the interest payment, is sufficient to yield net proceeds (after payment of all costs) to cover the amount such withholding taxes; and (b) shall remit such amount withheld on behalf of the Company to the proper tax authorities within the period of time prescribed for this purpose under applicable laws.

(iii) to reduce with respect to Debentureholders of any particular series any percentage stated in this Section 12.1 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.

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.

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.

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.

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.

 - 104 -

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 or she shall then be the holder. In the case of any Debenture denominated in a currency or currency unit other than United States dollars, the principal amount thereof for these purposes shall be computed in United States 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.

12.9 Proxies

A Debentureholder may be present and vote at any meeting of Debentureholders by an authorized representative. The Company (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 any or all of the following matters:

(a) 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;

(b) the deposit of instruments appointing proxies at such place as the Trustee, the Company or the Debentureholder convening the meeting, as the case may be, may, in the notice convening the meeting, direct and the time, if any, before the holding of the meeting or any adjournment thereof by which the same must be deposited; and

(c) the deposit of instruments appointing proxies at some approved place or places other than the place at which the meeting is to be held and enabling particulars of such instruments appointing proxies to be mailed, faxed, or sent by other electronic means before the meeting to the Company or to the Trustee at the place where the same is to be held and for the voting of proxies so deposited as though the instruments themselves were produced at the meeting.

 - 105 -

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.

12.10 Persons Entitled to Attend Meetings

The Company and the Trustee, by their respective officers, employees and directors, the Auditors of the Company and the legal advisors of the Company, the Trustee or any Debentureholder (and their legal advisors) 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. Every such committee may elect its chairman and may make regulations respecting its quorum, the calling of its meetings and the filling of vacancies occurring in its number and its procedure generally.

Article 14
CONCERNING THE TRUSTEE

14.1 No Conflict of Interest

The Trustee represents to the Company 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 90 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. The Trustee also serves as the transfer agent for the Common Shares.

14.2 Replacement of Trustee

(a) The Trustee may resign its trust and be discharged from all further duties and liabilities hereunder by giving to the Company 90 days' notice in writing or such shorter notice as the Company 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 90 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 Company shall forthwith appoint a new Trustee unless a new Trustee has already been appointed by the Debentureholders. Failing such appointment by the Company, 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 Company's expense, for the appointment of a new Trustee but any new Trustee so appointed by the Company 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 Company authorized to carry on the business of a trust company in all of the Provinces and Territories 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.

 - 111 -

(b) 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 Company, 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 Company 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 Company.

14.3 Duties of Trustee

The Trustee may nevertheless, in its discretion, require further proof in cases where it deems further proof desirable.

14.5 Evidence and Authority to Trustee, Opinions, etc.

(a) The Company 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 Company 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 Company, 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 Company written notice requiring it to furnish such evidence in relation to any particular action or obligation specified in such notice.

(e) The Company shall furnish or cause to be furnished to the Trustee at any time if the Trustee reasonably so requires, its certificate that the Company 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 Company 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 Company or as a result of any obligation imposed by this Indenture.

The Company shall pay or reimburse the Trustee for any reasonable fees, expenses and disbursements of such counsel or advisors.

14.8 Trustee May Deal in Debentures

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 Company or otherwise, without being liable to account for any profits made thereby.

i-80 GOLD CORP.

(A corporation existing under the laws of the Province of British Columbia)

8.00% SECURED CONVERTIBLE DEBENTURE

DUE February 22, 2027

i-80 GOLD CORP. (the "Corporation") for value received hereby acknowledges itself indebted and, subject to the provisions of the Convertible Debenture Indenture (the "Indenture") dated as of February 22, 2023 between the Corporation and TSX TRUST COMPANY (the "Trustee"), promises to pay to _______________, the registered holder hereof on February 22, 2027 or on such earlier date as the principal amount hereof may become due in accordance with the provisions of the Indenture (any such date, the "Maturity Date") the principal sum of • Dollars ($•) in lawful money of the United States on presentation and surrender of this Debenture at the office of the Trustee in Toronto, Ontario in accordance with and subject to the terms of the Indenture and, subject as hereinafter provided, to pay interest on the principal amount hereof from, and including, the date hereof, at the rate of 8.00% per annum (based on a year of 365 days), which shall be capitalized quarterly and payable on the Maturity Date; provided on the occurrence of an Event of Default, interest shall accrue at rate of 10.50%, compounded quarterly. For certainty, no cash interest payments are payable until the Maturity Date.

This initial debenture is one of the 8.00% Secured Convertible Debentures due 2027 (referred to herein as the "Debentures") of the Corporation issued or issuable in one or more series under the provisions of the Indenture. The Debentures authorized for issue immediately are limited to an aggregate principal amount of $65,000,000 in lawful money of the United States, in connection with the Offering. Reference is hereby expressly made to the Indenture for a description of the terms and conditions upon which the Debentures are or are to be issued and held and the rights and remedies of the holders of the 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 Debenture by acceptance hereof assents.

The 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.

Subject to the terms and conditions of the Indenture, the outstanding principal amount of the Debentures shall be repaid by the Company to the Debentureholders on the Maturity Date with a payment equal to 100% of the outstanding principal sum.

The Company shall satisfy its Interest Obligation on the Debentures on the Interest Payment Date (including, for greater certainty, following conversion or upon maturity) by delivering cash to the Trustee. Notwithstanding the foregoing, the Debentureholders shall have the option to elect to convert all or any portion of the accrued and unpaid interest, including, for greater certainty, any interest earned on interest previously accrued and added to the outstanding principal amount of Debentures, into Common Shares at a conversion price equal to the lesser of (i) the Conversion Price, or (ii) the Current Market Price for Interest at the time of the conversion of such amounts owing, subject in each case to the approval of the applicable Stock Exchange.

 A-3

Any part, being $1,000 or an integral multiple thereof, of the principal of this Debenture, provided that the principal amount of this Debenture is in a denomination in excess of $1,000, is convertible, at the option of the holder hereof, upon surrender of this Debenture at the principal office of the Trustee in Toronto, Ontario, at any time following the Issue Date and prior to the close of business on the Business Day preceding the Maturity Date or, if called for repurchase pursuant to a Change of Control on the last Business Day immediately prior to the payment date, into common shares of the Corporation ("Common Shares") (without adjustment, except as otherwise described in the Indenture) at a conversion price of $3.38 per Common Share (the "Original Conversion Price"), all subject to the terms and conditions and in the manner set forth in the Indenture. 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. If a Debenture is surrendered for conversion on the Interest Payment Date, 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 the 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 interest record date.

Upon the occurrence of a Change of Control, the holders of the Debentures shall, in their sole discretion, have the right to require the Corporation to purchase the Debentures (the "Change of Control Purchase Option") at a price equal to 104% of the principal amount thereof plus accrued and unpaid interest on such principal up to (but excluding) the date the Debentures are so repurchased. 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 surrendered for purchase pursuant to the Change of Control Purchase Option, the Corporation has the right to redeem all the remaining outstanding Debentures on the same date and at the same price.

The indebtedness, liabilities and obligations of the Company under this Indenture and under the Debentures, are direct, senior unsecured obligations of the Company ranking pari passu with all other current and future senior debt and other liabilities of the Company, and effectively subordinated to all current and future secured debt and other liabilities of the Company. The indebtedness, liabilities and obligations of the Company under this Indenture and under the Debentures will be guaranteed by the Limited Recourse Guarantor with recourse limited to a pledge of all present and future shares issued by the Guarantor. The indebtedness, liabilities and obligations of the Company under this Indenture and under the Debentures will be guaranteed by the Guarantor, and such guarantee shall be secured by a first ranking security interest in and to all of the Guarantor's present and future real and personal property, including the Project.

The Indenture contains provisions making binding upon all holders of Debentures outstanding thereunder (or in certain circumstances specific series of 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 Debentures outstanding (or specific series), which resolutions or instruments may have the effect of amending the terms of this Debenture or the Indenture.

 A-4

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 Debenture.

This 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 offices of the Trustee in the City of Toronto 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 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 Debenture for cancellation. Thereupon a new Debenture or Debentures in the same aggregate principal amount shall be issued to the transferee in exchange hereof.

These Debentures and the Common Shares underlying these Debentures have not been and will not be registered under the U.S. Securities Act or under the securities laws of any state of the United States. Such securities may not be offered, sold, pledged or otherwise transferred in the United States or to U.S. Persons except in limited circumstances contemplated in the Indenture. If the certificate representing these Debentures contains a U.S. restrictive legend, then the certificates representing the Common Shares underlying these Debentures shall bear the same U.S. restrictive legend on such certificates.

This 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 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 Debenture and the Indenture, the terms of the Indenture shall govern.
