Upon and subject to the provisions and conditions of Article 6 and Section 3.9, the holder of each Initial Debenture shall have the right at such holder’s option, at any time prior to the close of business on the earlier of (i) the Business Day immediately preceding the Maturity Date of the Initial Debentures; or (ii) the fifth Business Day immediately preceding the Redemption Date if the Initial Debentures are called for redemption by notice to the holders of Initial Debentures in accordance with Sections 2.5(d) and 4.3 (the earlier of which will be the “Time of Expiry” for the purposes of Article 6 in respect of the Initial Debentures), to convert any part, being $1,000 or an integral multiple thereof, of the principal amount of a Debenture into Common Shares at the Conversion Price in effect on the Date of Conversion. To the extent a redemption is a redemption in part only of the Initial Debentures, such right to convert, if not exercised prior to the applicable Time of Expiry, shall survive as to any Initial Debentures not redeemed or converted and be applicable to the next succeeding Time of Expiry.

The Conversion Price in effect on the date hereof for each Common Share to be issued upon the conversion of Initial Debentures shall be equal to $4.15 such that approximately 240.96 Common Shares shall be issued for each $1,000 principal amount of Initial Debentures so converted. Except as provided below, no adjustment in the number of Common Shares to be issued upon conversion will be made for dividends or distributions on Common Shares issuable upon conversion, the record date for the payment of which precedes the date upon which the holder becomes a holder of Common Shares in accordance with Article 6, or for interest accrued on Initial Debentures surrendered. No fractional Common Shares will be issued, and holders will receive a cash payment in satisfaction of any fractional interest based on the Current Market Price as of the Date of Conversion, provided, however, that the Corporation shall not be required to make any payment of less

- 20 -

than $5.00. The Conversion Price applicable to, and the Common Shares, securities or other property receivable on the conversion of, the Initial Debentures is subject to adjustment pursuant to the provisions of Section 6.5. The Conversion Price will not be adjusted for accrued interest on the Debentures.

Holders converting Debentures shall receive accrued and unpaid interest thereon from the period of the last Interest Payment Date prior to the Date of Conversion to the date that is one Business Day prior to the Date of Conversion.

Notwithstanding any other provisions of this Indenture, if a Debenture is surrendered for conversion on an Interest Payment Date or during the five preceding Business Days, the Person or Persons entitled to receive Common Shares in respect of the Debenture so surrendered for conversion shall not become the holder or holders of record of such Common Shares until the Business Day following such Interest Payment Date.

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

(h)

On redemption or maturity of the Initial Debentures, the Corporation may, at its option and subject to the provisions of Section 2.5, Section 4.6 and Section 4.10, as applicable, and subject to regulatory or stock exchange approval, elect to satisfy its obligation to pay all or a portion of the aggregate principal amount of the Initial Debentures due on redemption or maturity, by issuing and delivering to such holders of Initial Debentures Freely Tradeable Common Shares pursuant to the provisions of Sections 4.6 and 4.10, as applicable. If the Corporation elects to exercise such option, it shall provide details in the Redemption Notice or deliver a maturity notice (the “Maturity Notice”) to the holders of the Initial Debentures in substantially the form of Schedule “C” and provide the necessary details. Any accrued and unpaid interest on such Initial Debentures to be redeemed or repaid will be paid in cash.

(i)

The Initial Debentures shall be issued in denominations of $1,000 and integral multiples of $1,000. Each Initial Debenture and the certificate of the Trustees endorsed thereon shall be issued in substantially the form set out in Schedule “A” (provided that Initial Debentures issued in the form of Definitive Debentures shall be issued without the Global Debenture Legend and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto), with such insertions, omissions, substitutions or other variations as shall be required or permitted by this Indenture, and may have imprinted or otherwise reproduced thereon such legend or legends or endorsements, not inconsistent with the provisions of this Indenture, as may be required to comply with any law or with any rules or regulations pursuant thereto or with any rules or regulations of any securities exchange or securities regulatory authority or to conform with general usage, all as may be determined by the Board of Directors executing such Initial Debenture in accordance with Section 2.8, as conclusively evidenced by their execution of an Initial Debenture. Each Initial Debenture shall additionally bear such

- 21 -

distinguishing letters and numbers as the Trustees shall approve. Notwithstanding the foregoing, an Initial Debenture may be in such other form or forms as may, from time to time, be, approved by a resolution of the Board of Directors, or as specified in an Officers’ Certificate.

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

The Initial Debentures shall be issued in the form of one or more Global Debentures and/or one or more Definitive Debentures at the option of the Corporation.

The Global Debentures will be registered in the name of the Depository which, as of the date hereof, shall be CDS Clearing and Depository Services Inc. (or any nominee of the Depository). No Beneficial Holder will receive definitive certificates representing their interest in Debentures except as provided in this Section 2.5(i) and Section 3.2. A Global Debenture may be exchanged for Definitive Debentures, or transferred to and registered in the name of a Person other than the Depository for such Global Debentures or a nominee thereof, as provided in Section 3.2.

The Definitive Debentures will be registered in the names of each holder thereof as provided in Section 3.1. A Definitive Debenture may be exchanged, or transferred to and registered in the name of a Person other than the registered holder thereof, as provided in Section 3.2.

(j)

Upon and subject to the provisions of Article 10, the Corporation may elect, from time to time, subject to any required regulatory or stock exchange approval, to satisfy all or part of its Interest Obligation on the Initial Debentures on any Interest Payment Date (including, for greater certainty, following conversion or upon maturity or redemption) by delivering: (i) cash, (ii) Freely Tradeable Common Shares; or (iii) a combination of (i) and (ii) to the Trustees pursuant to the Common Share Interest Payment Election.

(k)

Within 30 days following the occurrence of a Change of Control, and subject to the provisions and conditions of this Section 2.5(k), the Corporation shall be obligated to make the Change of Control Purchase Offer in writing to holders of the Initial Debentures then outstanding. The terms and conditions of such obligation are set forth below:

(i)

Within 30 days following the occurrence of a Change of Control, the Corporation shall deliver to the Trustees, and the Trustees shall promptly deliver to the holders of the Initial Debentures, a notice stating that there has been a Change of Control and specifying the date on which such Change of Control occurred and the circumstances or events giving rise to such Change of Control (a “Change of Control Notice”) together with an offer in writing (the “Change of Control Purchase Offer”) to, at the option of the holder of the Initial Debentures, either: (i) purchase, on the Change of Control Purchase Date (as defined below), all (or any portion

- 22 -

actually tendered to such offer) of the Initial Debentures then outstanding from the holders thereof made in accordance with the requirements of Applicable Securities Legislation and U.S. Securities Laws at a price per Initial Debenture equal to 100% of the principal amount thereof (the “Offer Price”) plus accrued and unpaid interest on such Initial Debentures up to, but excluding, the Change of Control Purchase Date (collectively, the “Total Offer Price”); or (ii) convert the Initial Debentures into Common Shares at the Change of Control Conversion Price. If such Change of Control Purchase Date is after a record date for the payment of interest on the Initial Debentures but on or prior to an Interest Payment Date, then the interest payable on such date will be paid to the holder of record of the Debentures on the relevant record date in cash. 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 Purchase Offer are delivered to holders of Initial Debentures.

(ii)

The Change of Control Conversion Price will be calculated as follows:


COCCP	=	ECP/(1+(CP x (c/t))) where:

COCCP	=	is the Change of Control Conversion Price;

ECP	=	is the Conversion Price in effect on the date of the Change of Control;

CP	=	30.0%;

c	=	the number of days from and including the date of the Change of Control to but excluding the Maturity Date; and

t	=	the number of days from and including the issuance date to but excluding the Maturity Date.

(iii)

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

(iv)

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

(A)

the Corporation has exercised the 90% Redemption Right and is purchasing all outstanding Initial Debentures effective on the expiry of the Change of Control Purchase Offer at the Total Offer

- 23 -

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 transfer their Initial Debentures to the Corporation on the same terms as those holders that accepted the Change of Control Purchase Offer and must send their respective Initial Debentures, duly endorsed for transfer, to the Trustees within 10 days after the sending of such notice; and

(C)

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

(v)

The Corporation 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 Trustees or any other paying agent to the order of the Trustees, such sums of money as are sufficient to pay the Total Offer Price of the Initial Debentures to be purchased or redeemed by the Corporation on the Change of Control Purchase Date, provided the Corporation may elect to satisfy this requirement by providing the Trustees with a certified cheque or wire transfer for such amounts required under this Section 2.5(k)(v) post-dated to the date of expiry of the Change of Control Purchase Offer. The Corporation shall also deposit with the Trustees a sum of money sufficient to pay any charges or expenses which may be incurred by the Trustees in connection with such purchase. Every such deposit shall be irrevocable. From the sums so deposited, the Trustees shall pay or cause to be paid to the holders of such Initial Debentures, the Total Offer Price to which they are entitled on the Corporation’s purchase.

(vi)

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

(vii)

Initial Debentures for which holders have accepted the Change of Control Purchase Offer and Initial Debentures which the Corporation has elected to redeem in accordance with this Section 2.5(k) shall become due and payable at the Total Offer Price on the Change of Control Purchase Date,

- 24 -

in the same manner and with the same effect as if it were the date of maturity specified in such Initial Debentures, anything therein or herein to the contrary notwithstanding, and from and after the Change of Control Purchase Date, if the money necessary to purchase or redeem, or the Common Shares necessary to purchase or redeem, the Initial Debentures shall have been deposited as provided in this Section 2.5(k) and affidavits or other proofs as to the publication and/or mailing of such notices shall have been lodged with it, interest on the Initial Debentures shall cease. If any question shall arise as to whether any notice has been given as above provided and such deposit made, such question shall be decided by the Trustees whose decision shall be final and binding upon all parties.

(viii)

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

- 25 -

(ix)

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

(l)

Holders of the Initial Debentures shall have a right to require the Corporation to purchase up to 20% of the Initial Debentures on the following terms and conditions:

(i)

Each holder of Initial Debentures shall have the right (the “Put Right”) to require the Corporation to purchase up to 20% of the Initial Debentures held by such holder on the Put Date at a price equal to 100% of the principal amount thereof (the “Put Price”) plus accrued and unpaid interest (less any tax required by law to be deducted) on such Initial Debentures up to, but excluding, the Put Date (collectively, the “Total Put Price”).

(ii)

To exercise the Put Right, a holder of Initial Debentures must deliver to the Trustees, not less than 10 Business Days prior to the Put Date, written notice of the holder’s exercise of the Put Right in the form attached as Schedule “E” hereto together with (A) the Initial Debentures with respect to which the right is being exercised, duly endorsed for transfer, or (B) if the Initial Debentures have been issued as Global Debentures, a duly endorsed form of transfer.

(iii)

The Corporation shall, on or before 11:00 a.m., Toronto time on the Business Day immediately prior to the Put Date, deposit with the Trustees or any paying agent to the order of the Trustees, such sums of money as are sufficient to pay the Total Put Price of the Initial Debentures to be purchased by the Corporation on the Put Date, provided the Corporation may elect to satisfy this requirement by providing the Trustees with a certified cheque for such amounts post-dated to the Put Date or the Corporation may satisfy this requirement by an electronic funds transfer of such sums of money on the Business Day prior to the Put Date.

(iv)

Upon surrender of any Initial Debentures for payment of the Total Put Price, the portion of the Initial Debentures that are purchased pursuant to the Put Right shall forthwith be cancelled and the Corporation shall execute and the Trustees shall certify and deliver without charge to the holder thereof or upon the holder’s order, one or more new Initial Debentures for the portion of the principal amount of the Initial Debentures not purchased.

(v)

If the holder of any Initial Debenture to be purchased pursuant to a Put Right shall fail on or before the Put Date to surrender such holder’s Initial Debenture or duly endorsed form of transfer or shall not within such time accept payment of the moneys payable, or give such receipt therefor, if any, as the Trustees may require, such moneys may be set aside in trust without interest, either in deposit with the Trustees or in a chartered bank

- 26 -

for the benefit of the Trustees, and such setting aside shall for all purposes be deemed a payment to the holder of the Initial Debentures of the sum so set aside and the Initial Debentures that were so purchased shall thereafter not be considered as outstanding hereunder and the holder of such Initial Debentures shall have no other right in respect of such purchased Initial Debentures except to receive payment of the moneys so paid and deposited, upon surrender and delivery of such holder’s Initial Debenture, of the Total Put Price. If any money required to be deposited hereunder with the Trustees or any depositary or paying agent on account of principal or interest, if any, on Initial Debentures issued hereunder shall remain so deposited for a period of ten years from the Put Date, then to the extent permitted by law, such moneys, together with any accumulated interest thereon, shall at the end of such period be paid over or delivered over by the Trustees or such depositary or paying agent to the Corporation and the Trustees shall not be responsible to holder of the Initial Debentures for any amounts owing to them.

2.6

Certification and Delivery of Debentures

The Corporation may from time to time request the Trustees to certify and deliver Initial Debentures or Additional Debentures of any series by delivering to the Trustees the documents referred to below in this Section 2.6 whereupon the Trustees shall certify such Debentures and cause the same to be delivered in accordance with the Written Direction of the Corporation referred to below or pursuant to such procedures acceptable to the Trustees as may be specified from time to time by a Written Direction of the Corporation. The maturity date, issue date, interest rate (if any) and any other terms of the Debentures of such series, other than with respect to the Initial Debentures, shall be set forth in or determined by or pursuant to such Written Direction of the Corporation and procedures. In certifying such Debentures, the Trustees shall be entitled to receive and shall be fully protected in relying upon, unless and until such documents have been superseded or revoked:

(a)

an Officers’ Certificate and/or executed supplemental indenture by or pursuant to which the form and terms of the Additional Debentures were established;

(b)

a Written Direction of the Corporation requesting certification and delivery of Debentures and setting forth delivery instructions, provided that, with respect to Additional Debentures of a series subject to a Periodic Offering:

(i)

such Written Direction of the Corporation may be delivered by the Corporation to the Trustees prior to the delivery to the Trustees of such Additional Debentures of such series for certification and delivery;

(ii)

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

- 27 -

(iii)

the maturity date or dates, issue date or dates, interest rate or rates (if any) and any other terms of Additional Debentures of such series shall be determined by an executed supplemental indenture or by Written Direction of the Corporation or pursuant to such procedures; and

(iv)

if provided for in such procedures, such Written Direction of the Corporation may authorize certification and delivery pursuant to oral or electronic instructions from the Corporation which oral or electronic instructions shall be promptly confirmed in writing;

(c)

an opinion of Counsel, in form and substance satisfactory to the Trustees, acting reasonably, to the effect that all requirements imposed by this Indenture and by law in connection with the proposed issue of the Debentures have been complied with, subject to the delivery of certain documents or instruments specified in such opinion, and that upon the execution and authentication of the Debentures, the Debentures will be valid and binding obligations of the Corporation, enforceable in accordance with their terms; and

(d)

an Officers’ Certificate (which Officers’ Certificate shall be in such form that satisfies all applicable laws) certifying that the Corporation is not in default under this Indenture, that the terms and conditions for the certification and delivery of the Debentures (including those set forth in Section 15.5), have been complied with subject to the delivery of any documents or instruments specified in such Officers’ Certificate and that no Event of Default exists or will exist upon such certification and delivery.

2.7

Issue of Global Debentures

(a)

The Corporation may specify that the Debentures of a series are to be issued in whole or in part as one or more Global Debentures registered in the name of a Depository, or its nominee, designated by the Corporation in the Written Direction of the Corporation delivered to the Trustees at the time of issue of such Debentures, and in such event the Corporation shall execute and the Trustees shall certify and deliver one or more Global Debentures that shall:

(i)

represent an aggregate amount equal to the principal amount of the outstanding Debentures of such series to be represented by one or more Global Debentures;

(ii)

be delivered by the Trustees to such Depository or pursuant to such Depository’s instructions; and

(iii)

bear a legend substantially to the following effect:

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF CDS CLEARING AND DEPOSITORY SERVICES INC. (“CDS”) TO ENERGY FUELS INC. (THE “ISSUER”) OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IN RESPECT THEREOF IS REGISTERED IN

- 28 -

THE NAME OF CDS & CO., OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS (AND ANY PAYMENT IS MADE TO CDS & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED HOLDER HEREOF, CDS & CO., HAS A PROPERTY INTEREST IN THE SECURITIES REPRESENTED BY THIS CERTIFICATE HEREIN AND IT IS A VIOLATION OF ITS RIGHTS FOR ANOTHER PERSON TO HOLD, TRANSFER OR DEAL WITH THIS CERTIFICATE.

TRANSFERS OF THIS DEBENTURE SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF CDS & CO. OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR’S NOMINEE.”

(b)

Each Depository designated for a Global Debenture must, at the time of its designation and at all times while it serves as such Depository, be a clearing agency registered or designated under the securities legislation of the jurisdiction where the Depository has its principal offices.

(c)

Global Debentures issued to the Depository may be surrendered to the Trustees for an electronic position on the register of Debentureholders to be maintained by the Trustees in accordance with Section 3.2(a). All Debentures maintained in such electronic position will be valid and binding obligations of the Corporation, entitling the registered holders thereof to the same benefits as those registered holders who hold Debentures in physical form. This Indenture and the provisions contained herein will apply, mutatis mutandis, to such Debentures held in such electronic position.

The Debentures and the Common Shares issuable upon conversion thereof have not been and will not be registered under the 1933 Act or under any state securities laws.

2.8

Execution of Debentures

All Debentures shall be signed (either manually or by electronic signature) by any one authorized director or officer of the Corporation holding office at the time of signing. An electronic signature upon a Debenture shall for all purposes of this Indenture be deemed to be the signature of the Person whose signature it purports to be.

Notwithstanding that any Person whose signature, either manual or electronic, appears on a Debenture as a director or officer may no longer hold such office at the date of the Debenture or at the date of the certification and delivery thereof, such Debenture shall be valid and binding upon the Corporation and entitled to the benefits of this Indenture.

2.9

Certification

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 manually certified by or on behalf of the Trustees

- 29 -

substantially in the form set out in this Indenture, in the relevant supplemental indenture, or in some other form approved by the applicable Trustee. Such certification on any Debenture shall be conclusive evidence that such Debenture is duly issued, is a valid obligation of the Corporation and the holder is entitled to the benefits hereof.

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

2.10

Interim Debentures or Certificates

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

2.11

Mutilation, Loss, Theft or Destruction

In case any of the Debentures issued hereunder shall become mutilated or be lost, stolen or destroyed, the Corporation, in its discretion, may issue, and thereupon the applicable Trustee shall certify and deliver, a new Debenture upon surrender and cancellation of the mutilated Debenture, or in the case of a lost, stolen or destroyed Debenture, in lieu of and in substitution for the same, and the substituted Debenture shall be in a form approved by the Trustees and shall be

- 30 -

entitled to the benefits of this Indenture and rank equally in accordance with its terms with all other Debentures issued or to be issued hereunder. In case of loss, theft or destruction the applicant for a substituted Debenture shall furnish to the Corporation and to the Trustees such evidence of the loss, theft or destruction of the Debenture as shall be satisfactory to them in their discretion and shall also furnish an indemnity and surety bond satisfactory to them in their discretion. The applicant shall pay all reasonable expenses incidental to the issuance of any substituted Debenture.

2.12

Concerning Interest

(a)

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

(b)

Unless otherwise specifically provided in the terms of the Debentures of any series, interest for any period shall be computed on the basis of a year of 365 days and the actual number of days elapsed in such period. With respect to any series of Debentures, for the purposes disclosure under the Interest Act (Canada), 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 such calendar year of calculation and dividing it by the number of days in the deemed year.

2.13

Debentures to Rank Pari Passu

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

2.14

Payments of Amounts Due on Maturity

Except as may otherwise be provided herein or in any supplemental indenture in respect of any series of Debentures and subject to Section 4.10, payments of amounts due upon maturity of the Debentures will be made in the following manner. The Corporation will establish and maintain with the Trustees a Maturity Account for each series of Debentures. Each such Maturity Account shall be maintained by and be subject to the control of the Trustees 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 Corporation will deliver to the Trustees a certified cheque or wire transfer for deposit in the applicable

- 31 -

Maturity Account in an amount sufficient to pay the cash amount payable in respect of such Debentures (including the principal amount together with any accrued and unpaid interest thereon). The Trustees, on behalf of the Corporation, will pay to each holder entitled to receive payment the principal amount of and premium (if any) and accrued and unpaid interest on the Debenture, upon surrender of the Debenture at any branch of the Trustees designated for such purpose by the Corporation and the Trustees. The delivery of such funds to the Trustees for deposit to the applicable Maturity Account will satisfy and discharge the liability of the Corporation for the Debentures to which the delivery of funds relates to the extent of the amount delivered 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.

2.15

Payment of Interest

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

(a)

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

- 32 -

with the same effect as though payment had been made in the manner provided above.

(b)

All payments of interest on the Global Debenture shall be made by electronic funds transfer or certified cheque made payable to the Depository or its nominee on the day interest is payable for subsequent payment to Beneficial Holders of the applicable Global Debenture, unless the Corporation, the Trustees and the Depository otherwise agree. None of the Corporation, the Trustees or any agent of the Trustees for any Debenture issued as a Global 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 Global Debenture or for maintaining, reviewing, or supervising any records relating to such beneficial interests.

2.16

Tax Gross Up

(a)

Unless otherwise expressly provided in the terms of the Debentures, all payments made by the Corporation, Depository, a Depository Participant or a financial intermediary having an account with any Depository Participant making such payment (the “Payor”) under or with respect to the Debentures (including for greater certainty and without limitation, the delivery of Common Shares or other property in connection with the exercise of a conversion of Debentures), to a holder will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other governmental charge including penalties, interest and other liabilities related thereto imposed or levied by or on behalf of the Government of Canada or of any province or territory thereof or by any authority or agency therein or thereof having power to tax (hereinafter “Canadian Taxes”), unless there is an obligation on the Payor to withhold or deduct Canadian Taxes by law or by the interpretation or administration thereof. Notwithstanding anything to the contrary contained herein or in any Debenture, if the Payor is so required to withhold or deduct any amount for or on account of Canadian Taxes from any payment made under or with respect to the Debentures, the Corporation will pay on behalf of each holder as additional interest such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by each holder after such withholding or deduction (and after deducting any Canadian Taxes on such Additional Amounts) will not be less than the amount the holder would have received if such Canadian Taxes had not been withheld or deducted. However, no Additional Amounts will be payable with respect to a payment made to a holder (such holder, an “Excluded Holder”) in respect of the beneficial owner thereof which is subject to such Canadian Taxes by reason of such holder being a resident, domicile or national of, or engaged in business or maintaining a permanent establishment or other presence in, or otherwise having some present or former connection with Canada or any province or territory thereof otherwise than by the mere holding of Debentures or the receipt of payments thereunder.

(b)

The Corporation will make payment of all Additional Amounts to each Payor and each Payor will:

- 33 -

(i)

make such withholding or deduction;

(ii)

remit the full amount deducted or withheld to the relevant authority in accordance with applicable law; and

(iii)

provide to the holders of Debentures copies of tax receipts and other documents evidencing such payment by the Corporation in a timely fashion.

(c)

The Corporation will indemnify and hold harmless each holder (other than an Excluded Holder), and, within 10 Business Days upon a written request in respect thereof, reimburse each such holder for the amount, excluding any payment of Additional Amounts by the Corporation, of:

(i)

any Canadian Taxes so levied or imposed and paid by such holder as a result of payments made under or with respect to the Debentures;

(ii)

any liability (including penalties, interest and expenses) arising therefrom or with respect thereto; and

(iii)

any Canadian Taxes imposed with respect to any reimbursement under clause (i) or (ii) in this paragraph, but excluding any such Canadian Taxes on such holder’s net income 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.

(d)

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.

(e)

If Canadian Taxes are or were required to be withheld or deducted in respect of amounts payable or paid by any Payor from any payment to be made or made hereunder pursuant to applicable law or by the interpretation or administration thereof, such Payor shall provide the Corporation with notice in writing that such withholding or deduction is or was required and certifying all of the facts and circumstances supporting the conclusion that such withholding or deduction is or was required. Such certificate shall constitute prima facie evidence of the Corporation’s obligation to pay the Additional Amounts required under Section 2.16(b).

(f)

If Canadian Taxes are required to be withheld or deducted from any payment made hereunder pursuant to applicable law or by the interpretation or administration thereof and the Corporation is required to pay Additional Amounts to a holder pursuant to this Section 2.16, or indemnify a holder under Section 2.16(c), the holder shall use its commercially reasonable efforts to cooperate with the Corporation in taking any action to dispute, object to or appeal the liability of the holder for Canadian Taxes or in claiming a refund of amounts remitted as

- 34 -

Canadian Taxes (or any objection or appeal in connection therewith) (collectively, “Tax Proceedings”).

Without limiting the generality of the foregoing:

(i)

The holder agrees that the Corporation shall, at its own expense, have the right to initiate and conduct and have carriage and control of the Tax Proceedings and where necessary for the purposes of the Tax Act in the name of, and on behalf of, the holder.

(ii)

The holder shall use its commercially reasonable efforts to do all acts and sign all documents that may be necessary or desirable in order to initiate or conduct the Tax Proceedings where such Tax Proceedings need to be initiated or conducted in the name of, or on behalf of, the holder.

(iii)

If the holder receives a refund of any amount with respect to Canadian Taxes (including interest, on such refund, if any) for which the Corporation grossed up the holder, the holder shall forthwith pay the amount of any such refund (including interest, on such refund, if any less any applicable withholding tax), to such extent, to the Corporation and hereby assigns the right to any such refund, to such extent, to the Corporation.

For certainty, the holder shall provide any information regarding itself and/or its beneficial owners to the Corporation as may be desirable or necessary to permit the Corporation to comply with its withholding obligations and advance any Tax Proceedings. To the extent the holder incurs any reasonable expense or liability in connection with its activities pursuant to this Section 2.16(e), the Corporation shall reimburse and indemnify the holder within two Business Days of request by the holder. The Corporation shall not disclose any information provided herein without the express written consent of the holder, and shall not use any information provided under this Section 2.16 for any purpose other than in connection with the Tax Proceedings.

(g)

In order to assist the Corporation in complying with this Section 2.16, the Trustees will request from the Depository and provide to the Corporation within two Business Days of each record date, a list of Depository participants who hold Debentures as of the record date.

2.17

FATCA

The Corporation agrees (i) to provide the Trustees with such reasonable information as it has in its possession to enable the Trustees to determine whether any payments pursuant to the Indenture are subject to the withholding requirements described in Section 1471(b) of the U.S. Internal Revenue Code of 1986 (the “Code”) or otherwise imposed pursuant to Sections 1471 through 1474 of the Code and any regulations, or agreements thereunder or official interpretations thereof (“Applicable Law”), and (ii) that the Trustees shall be entitled to make any withholding or deduction from payments under the Indenture to the extent necessary to comply with Applicable Law, for which the Trustees shall not have any liability.

(b)

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

(i)

- 36 -

another nominee of such Depository or by a Depository or its nominee to a successor Depository or its nominee;

(ii)

Global Debentures may be transferred at any time after the Depository for such Global Debentures (i) has notified the Trustees, or the Corporation has notified the Trustees, that it is unwilling or unable to continue as Depository for such Global Debentures, or (ii) ceases to be eligible to be a Depository under Section 2.7(b), provided that at the time of such transfer the Corporation has not appointed a successor Depository for such Global Debentures;

(iv)

Global Debentures may be transferred at any time after an Event of Default has occurred and is continuing with respect to the Debentures of the series issued as a Global Debenture, provided that Beneficial Holders representing, in the aggregate, not less than 25% of the aggregate principal amount of the Debentures of such series advise the Depository in writing, through the Depository Participants, that the continuation of the book-entry only registration system for such series of Debentures is no longer in their best interest and also provided that at the time of such transfer the Event of Default has not been waived pursuant to Section 8.3;

(vi)

Global Debentures may be transferred if required by applicable law; or

(vii)

Global Debentures may be transferred if the book-entry only registration system ceases to exist.

the Depository will make book-entry transfers among the Depository Participants; and

(iv)

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

(d)

Whenever a notice or other communication is required to be provided to Debentureholders, unless and until definitive certificate(s) have been issued to Beneficial Holders pursuant to this Section 3.2, the Trustees shall provide all such notices and communications to the Depository and the Depository shall deliver such notices and communications to such Beneficial Holders in accordance with U.S. Securities Laws and Applicable Securities Legislation. Upon the termination of the book-entry only registration system on the occurrence of one of the conditions specified in Section 3.2(b) with respect to a series of Debentures issued hereunder, the Trustees shall notify all applicable Depository Participants and Beneficial Holders, through the Depository, of the availability of Definitive Debenture certificates. Upon surrender by the Depository of the certificate(s) representing the Global Debentures and receipt of new registration instructions from the Depository, the Trustees shall deliver the Definitive Debenture certificates for such Debentures to the holders thereof in accordance with the new registration instructions and thereafter, the registration and transfer of such Debentures will be governed by Section 3.1 and the remaining Sections of this Article 3.

3.4

No Notice of Trusts

3.5

The registers referred to in Sections 3.1 and 3.2 shall at all reasonable times be open for inspection by the Corporation, the Trustees or any Debentureholder. Every registrar, including

Subject to Sections 3.1, 3.2 and 3.7, Debentures in any authorized form or denomination, other than Global Debentures, may be exchanged for Debentures in any other authorized form or denomination, of the same series and date of maturity, bearing the same interest rate and of the same aggregate principal amount as the Debentures so exchanged.

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

ARTICLE 4

REDEMPTION AND PURCHASE OF DEBENTURES

4.1

Applicability of Article

Subject to regulatory and stock exchange approval, Sections 2.5(d) and 2.5(e) and Article 5, the Corporation shall have the right at its option to redeem, either in whole at any time or in part from time to time before maturity, either by payment of money, by issuance of Freely Tradeable Common Shares as provided in Section 4.6 or any combination thereof, any Debentures issued hereunder of any series which by their terms are made so redeemable (subject, however, to any applicable restriction on the redemption of Debentures of such series) at such rate or rates of premium, if any, and on such date or dates and in accordance with such other provisions as shall have been determined at the time of issue of such Debentures and as shall have been expressed in this Indenture, in the Debentures, in an Officers’ Certificate, or in a supplemental indenture authorizing or providing for the issue thereof, or in the case of Additional Debentures issued pursuant to a Periodic Offering, in the Written Direction of the Corporation requesting the certification and delivery thereof.

Subject to regulatory and stock exchange approval and Article 5, the Corporation shall also have the right at its option to repay, either in whole or in part, on maturity, either by payment of money in accordance with Section 2.14, by issuance of Freely Tradeable Common Shares as provided in Section 4.10 or any combination thereof, any Debentures issued hereunder of any series which by their terms are made so repayable on maturity (subject however, to any applicable restriction on the repayment of the principal amount of the Debentures of such series) at such rate or rates of premium, if any, and on such date or dates and in accordance with such other provisions as shall have been determined at the time of issue of such Debenture and shall have been expressed in this Indenture, in the Debentures, in an Officers’ Certificate, or in a supplemental indenture authorizing or providing for the issue thereof, or in the case of Additional Debentures issued pursuant to a Periodic Offering, in the Written Direction of the Corporation requesting the certification and delivery thereof.

4.2

Partial Redemption

If less than all the Debentures of any series for the time being outstanding are at any time to be redeemed, or if a portion of the Debentures being redeemed are being redeemed for cash and a portion of such Debentures are being redeemed by the payment of Freely Tradeable Common Shares pursuant to Section 4.6, the Debentures to be so redeemed shall be selected by the

- 41 -

Trustees on a pro rata basis to the nearest multiple of $1,000 in accordance with the principal amount of the Debentures registered in the name of each holder or in such other manner as the Trustees deems equitable, subject to the approval of the Toronto Stock Exchange or such other exchange on which the Debentures are then listed, as may be required from time to time. Unless otherwise specifically provided in the terms of any series of Debentures, no Debenture shall be redeemed in part unless the principal amount redeemed is $1,000 or a multiple thereof. For this purpose, the Trustees may make, and from time to time vary, regulations with respect to the manner in which such Debentures may be drawn for redemption and regulations so made shall be valid and binding upon all holders of such Debentures notwithstanding that as a result thereof one or more of such Debentures may become subject to redemption in part only or for cash only. In the event that one or more of such Debentures becomes subject to redemption in part only, upon surrender of any such Debentures for payment of the Redemption Price, together with interest accrued to but excluding the Redemption Date, the Corporation shall execute and the Trustees shall certify and deliver without charge to the holder thereof or upon the holder’s order one or more new Debentures for the unredeemed part of the principal amount of the Debenture or Debentures so surrendered or, with respect to a Global Debenture, the Trustees shall make notations on the Global Debenture of the principal amount thereof so redeemed. Unless the context otherwise requires, the terms “Debenture” or “Debentures” as used in this Article 4 shall be deemed to mean or include any part of the principal amount of any Debenture which in accordance with the foregoing provisions has become subject to redemption.

4.3

Notice of Redemption

Notice of redemption (the “Redemption Notice”) of any series of Debentures shall be given to the holders of the Debentures so to be redeemed not more than 60 days nor less than 30 days prior to the date fixed for redemption (the “Redemption Date”) in the manner provided in Section 14.2. Every such notice shall specify the aggregate principal amount of Debentures called for redemption, the Redemption Date, the Redemption Price and the places of payment and shall state that interest upon the principal amount of Debentures called for redemption shall cease to be payable from and after the Redemption Date. In addition, unless all the outstanding Debentures are to be redeemed, the Redemption Notice shall specify:

(a)

the distinguishing letters and numbers of the registered Debentures which are to be redeemed (or of such thereof as are registered in the name of such Debentureholder);

(b)

in the case of a published notice, the distinguishing letters and numbers of the Debentures which are to be redeemed or, if such Debentures are selected by terminal digit or other similar system, such particulars as may be sufficient to identify the Debentures so selected;

(c)

in the case of a Global Debenture, that the redemption will take place in such manner as may be agreed upon by the Depository, the Trustees and the Corporation; and

(d)

in all cases, the principal amounts of such Debentures or, if any such Debenture is to be redeemed in part only, the principal amount of such part.

- 42 -

In the event that all Debentures to be redeemed are registered Debentures, publication shall not be required.

4.4

Debentures Due on Redemption Dates

Notice having been given as aforesaid, all the Debentures so called for redemption shall thereupon be and become due and payable at the Redemption Price, together with accrued interest to but excluding the Redemption Date, on the Redemption Date specified in such notice, 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 such Redemption Date, if the monies necessary to redeem, or the Common Shares to be issued to redeem, such Debentures shall have been deposited as provided in Section 4.5 and affidavits or other proof satisfactory to the Trustees as to the publication and/or mailing of such notices shall have been lodged with them, interest upon 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 Trustees whose decision shall be final and binding upon all parties in interest.

4.5

Deposit of Redemption Monies or Common Shares

Redemption of Debentures shall be provided for by the Corporation depositing with the Trustees or any paying agent to the order of the Trustees, 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, or certificates representing such Common Shares, or both as the case may be, as may be sufficient to pay the Redemption Price of the Debentures so called for redemption, plus accrued and unpaid interest thereon up to but excluding the Redemption Date, provided the Corporation may elect to satisfy this requirement by providing the Trustees with a certified cheque or wire transfer for such amounts required under this Section 4.5 post-dated to the Redemption Date. The Corporation shall also deposit with the Trustees a sum of money sufficient to pay any charges or expenses which may be incurred by the Trustees in connection with such redemption. Every such deposit shall be irrevocable. From the sums so deposited, or certificates so deposited, or both, the Trustees shall pay or cause to be paid, or issue or cause to be issued, to the holders of such Debentures so called for redemption, upon surrender of such Debentures, the principal, premium (if any) and interest (if any) to which they are respectively entitled on redemption.

4.6

Right to Repay Redemption Price in Common Shares

(a)

Subject to the receipt of any required regulatory and stock exchange approvals, Section 2.5(e) and the other provisions of this Section 4.6, the Corporation may, at its option, in exchange for or in lieu of paying the Redemption Price in money, elect to satisfy its obligation to pay all or any portion of the Redemption Price by issuing and delivering to holders on the Redemption Date that number of Freely Tradeable Common Shares obtained by dividing the aggregate principal amount of the outstanding Debentures (or applicable portion thereof to be satisfied by the issuance and delivery of Freely Tradeable Common Shares) by 95% of the then Current Market Price of the Common Shares on the Redemption Date (the “Common Share Redemption Right”); provided that, subject to the ability of the Corporation to exercise the Common Share Interest Payment Election in

- 43 -

accordance with Article 10, all accrued and unpaid interest thereon shall be payable to the holder in cash.

(b)

The Corporation shall exercise the Common Share Redemption Right by so specifying in the Redemption Notice, which shall be delivered to the Trustees and the holders of Debentures not more than 60 days and not less than 40 days prior to the Redemption Date, and shall also specify the aggregate principal amount of Debentures in respect of which it is exercising the Common Share Redemption Right in such notice.

(c)

The Corporation’s right to exercise the Common Share Redemption Right shall be conditional upon the following conditions being met on the Business Day preceding the Redemption Date:

(i)

the issuance of the Common Shares on the exercise of the Common Share Redemption Right shall be made in accordance with U.S. Securities Laws and Applicable Securities Legislation and such Common Shares shall be issued as Freely Tradeable Common Shares;

(ii)

such additional Freely Tradeable Common Shares shall be listed or conditionally approved for listing on each stock exchange on which the Common Shares are then listed, the Toronto Stock Exchange or national securities exchange or quoted in an inter-dealer quotation system of any registered national securities association;

(iii)

the Corporation shall be a reporting issuer in good standing under Applicable Securities Legislation;

(iv)

no Event of Default shall have occurred and be continuing;

(v)

the Trustees shall have received an Officers’ Certificate stating that conditions (i), (ii), (iii) and (iv) above have been satisfied and setting forth the number of Common Shares to be delivered for each $1,000 principal amount of Debentures and the Current Market Price of the Common Shares on the Redemption Date; and

If the foregoing conditions are not satisfied prior to the close of business on the Business Day preceding the Redemption Date, the Corporation shall pay the Redemption Price entirely in cash in accordance with Section 4.5 unless the Debentureholder waives the conditions which are not satisfied. In the event that the Corporation duly exercises its Common Share Redemption Right, upon presentation and surrender of the Debentures for payment on the Redemption Date, at any place where a register is maintained pursuant to Article 3 or any other

- 44 -

place specified in the Redemption Notice, the Corporation shall on or before 11:00 a.m. (Toronto time) on the Business Day immediately prior to the Redemption Date make the delivery to the Trustees for delivery to and on account of the holders, of certificates representing the Freely Tradeable Common Shares to which such holders are entitled.

(d)

No fractional Freely Tradeable Common Shares shall be delivered upon the exercise of the Common Share Redemption Right but, in lieu thereof, the Corporation shall pay to the Trustees for the account of the holders, at the time contemplated in this Section 4.6, the cash equivalent thereof determined on the basis of the Current Market Price of the Common Shares on the Redemption Date, provided, however, that the Corporation shall not be required to make any payment of less than $5.00.

(e)

A holder shall be treated as the shareholder of record of the Freely Tradeable Common Shares issued on due exercise by the Corporation of its Common Share Redemption Right effective immediately after the close of business on the Redemption Date, and shall be entitled to all substitutions therefor, all income earned thereon or accretions thereto and all dividends or distributions (including distributions and dividends in kind) thereon and arising thereafter, and in the event that the Trustees receives the same, they shall hold the same in trust for the benefit of such holder.

(f)

The Corporation shall 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 and delivery upon the exercise of the Corporation’s Common Share Redemption Right as provided herein, and shall issue to Debentureholders to whom Freely Tradeable Common Shares will be issued pursuant to exercise of the Common Share Redemption Right, such number of Freely Tradeable Common Shares as shall be issuable in such event. All Freely Tradeable Common Shares which shall be so issuable shall be duly and validly issued as fully paid and non-assessable.

The Corporation shall from time to time promptly pay, or make provision satisfactory to the Trustees for the payment of, all taxes and charges which may be imposed by the laws of Canada or any province thereof (except income tax, if any) which shall be payable with respect to the issuance or delivery of Freely Tradeable Common Shares to holders upon exercise of the Common Share Redemption Right pursuant to the terms of the Debentures and of this Indenture.

4.7

Failure to Surrender Debentures Called for Redemption

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 take delivery of certificates representing such Common Shares issuable in respect thereof, or give such receipt therefor, if any, as the Trustees may require, such redemption monies may be set aside in trust, or such certificates may be held in trust without interest, either in the deposit department of the Trustees or in a chartered bank, and such setting aside shall for all purposes be deemed a payment to the Debentureholder of the sum or Common Shares 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, or take delivery of the certificates so deposited, or both, upon surrender and delivery of such holder’s Debenture of the Redemption Price, as the case may be, of such Debenture, plus any accrued but unpaid interest thereon to but excluding the Redemption Date. In the event that any money, or certificates representing Common Shares, required to be deposited hereunder with the Trustees 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 five years less one day from the Redemption Date, then such monies or certificates representing Common Shares, together with any distribution paid thereon, shall at the end of such period be paid over or delivered over by the Trustees or such depository or paying agent to the Corporation on its demand, and thereupon the Trustees 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 Corporation shall have no rights in respect thereof except to obtain payment of the money or certificates due from the Corporation, subject to any limitation period provided by the laws of Ontario. Notwithstanding the foregoing, the Trustees will pay any remaining funds prior to the expiry of five years less one day after the Redemption Date to the Corporation upon receipt from the Corporation, of an unconditional letter of credit denominated and payable in the currency or currency unit in which the Debentures are payable and in an amount equal to or in excess of the amount of the remaining funds. If the remaining funds are paid to the Corporation prior to the expiry of five years less one day after the Redemption Date, the Corporation shall reimburse the Trustees for any amounts required to be paid by the Trustees to a holder of a Debenture pursuant to the redemption after the date of such payment of the remaining funds to the Corporation but prior to five years less one day after the redemption.

4.8

Cancellation of Debentures Redeemed

Subject to the provisions of Sections 4.2 and 4.9 as to Debentures redeemed or purchased in part, all Debentures redeemed and paid under this Article 4 shall forthwith be delivered to the Trustees and cancelled and no Debentures shall be issued in substitution for those redeemed.

4.9

Purchase of Debentures by the Corporation

Unless otherwise specifically provided with respect to a particular series of Debentures, the Corporation may, if it is not at the time in default hereunder, at any time and from time to time, purchase Debentures in the market (which shall include purchases from or through an investment dealer or a firm holding membership on a recognized stock exchange) or by tender or by contract or otherwise, at any price. All Debentures so purchased will be delivered to the Trustees and shall be cancelled and no Debentures shall be issued in substitution therefor.

- 46 -

If, upon an invitation for tenders, more Debentures are tendered at the same lowest price than the Corporation is prepared to accept, the Debentures to be purchased by the Corporation shall be selected by the Trustees on a pro rata basis or in such other manner as consented to by the Toronto Stock Exchange or such other exchange on which the Debentures are then listed which the Trustees consider appropriate, or in accordance with requirements, policies or procedures of the Depository, if applicable, from the Debentures tendered by each tendering Debentureholder who tendered at such lowest price. For this purpose the Trustees 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 Trustees shall certify and deliver such new Debenture or Debentures upon receipt of the Debenture so surrendered or, with respect to a Global Debenture, the Trustees shall make notations on the Global Debenture of the principal amount thereof so purchased.

4.10

Right to Repay Principal Amount in Common Shares

(a)

Subject to the receipt of any required regulatory and stock exchange approvals and the other provisions of this Section 4.10, the Corporation may, at its option, in exchange for or in lieu of repaying the Debentures in money, elect to satisfy its obligation to repay the principal amount of all or any portion of the principal amount of the Debentures outstanding, by issuing and delivering to holders on the Maturity Date of such Debentures that number of Freely Tradeable Common Shares obtained by dividing the principal amount of the Debentures (or applicable portion thereof to be satisfied by the issuance and delivery of Freely Tradeable Common Shares) by 95% of the then Current Market Price of the Common Shares on the Maturity Date (the “Common Share Repayment Right”); provided that all accrued and unpaid interest thereon shall be payable to the holder in cash.

(b)

The Corporation shall exercise the Common Share Repayment Right by so specifying in the Maturity Notice, which shall be delivered to the Trustees and the holders of Debentures not more than 60 days and not less than 40 days prior to the Maturity Date, and which shall also specify the aggregate principal amount of Debentures in respect of which it is exercising the Common Share Repayment Right on the Maturity Date.

If the foregoing conditions are not satisfied prior to the close of business on the Business Day preceding the Maturity Date, the Corporation shall pay the principal amount of the Debentures outstanding entirely in cash in accordance with Section 2.14, unless the Debentureholder waives the conditions which are not satisfied. The Corporation may not change the form of components or percentages of consideration to be paid for the Debentures once it has given the notice required to be given to Debentureholders hereunder, except as described in the preceding sentence. When the Corporation determines the actual number of Common Shares to be issued pursuant to the exercise of its Common Share Repayment Right, it will issue a press release on a national newswire disclosing the Current Market Price and such actual number of Common Shares.

(d)

In the event that the Corporation duly exercises its Common Share Repayment Right, upon presentation and surrender of the Debentures for payment on the Maturity Date, at any place where a register is maintained pursuant to Article 3 or any other place specified in the Maturity Notice, the Corporation shall on or before 11:00 a.m. (Toronto time) on the Business Day immediately prior to the Maturity Date make the delivery to the Trustees for delivery to and on account of the holders, of certificates representing the Freely Tradeable Common Shares to which such holders are entitled.

The delivery of such certificates to

- 48 -

(e)

No fractional Freely Tradeable Common Shares shall be delivered upon the exercise of the Common Share Repayment Right but, in lieu thereof, the Corporation shall pay to the Trustees for the account of the holders, at the time contemplated in Section 4.10(d), the cash equivalent thereof determined on the basis of the Current Market Price of the Common Shares on the Maturity Date, provided, however, that the Corporation shall not be required to make any payment of less than $5.00.

(f)

A holder shall be treated as the shareholder of record of the Freely Tradeable Common Shares issued on due exercise by the Corporation of its Common Share Repayment Right effective immediately after the close of business on the Maturity Date, and shall be entitled to all substitutions therefor, all income earned thereon or accretions thereto and all dividends or distributions (including distributions and dividends in kind) thereon and arising thereafter, and in the event that the Trustees receives the same, they shall hold the same in trust for the benefit of such holder.

(i)

The Corporation shall from time to time promptly pay, or make provision satisfactory to the Trustees for the payment of, all taxes and charges which may be imposed by the laws of Canada or any province thereof (except income tax, if any) which shall be payable with respect to the issuance or delivery of Freely Tradeable Common Shares to holders upon exercise of the Common Share Repayment Right pursuant to the terms of the Debentures and of this Indenture.

5.8

Knowledge of Trustees

Notwithstanding the provisions of this Article 5 or any provision in this Indenture or in the Debentures contained, the Trustees will not be charged with knowledge of any Senior Indebtedness or of any default in the payment thereof, or of the existence of any Event of Default or any other fact that would prohibit the making of any payment of monies to or by the Trustees, or the taking of any other action by the Trustees, unless and until the a responsible officer of a Trustee has received written notice thereof from the Corporation, any Debentureholder or any Senior Creditor.

For the purposes of this Article, a Debenture shall be deemed to be surrendered for conversion on the date (herein called the “Date of Conversion”) on which it is so surrendered when the register of the Trustees are open and in accordance with the provisions of this Article 6 or, in the case of a Global Debenture which the Trustees 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 post or other means of transmission, on the date on which it is received by the Trustees at one of their principal offices specified in Section 6.4(a); provided that if a Debenture is surrendered for conversion on a day on which the register of Common Shares or Debentures is closed, the Person or Persons entitled to receive Common Shares shall become the holder or holders of record of such Common Shares as at the date on which such registers are next reopened.

(c)

Any part, being $1,000 or an integral multiple thereof, of a Debenture in a denomination in excess of $1,000 may be converted as provided in this Article 6 and all references in this Indenture to conversion of Debentures shall be deemed to include conversion of such parts.

(d)

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 Canadian Trustee in accordance with Section 6.4(a), and the Canadian Trustee shall cancel the same and shall without charge forthwith certify 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 a Global Debenture, the Canadian Trustee shall make notations on the Global Debentures of the principal amount thereof so converted.

(e)

- 56 -

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 Common Shares pursuant to Section 6.4(b), 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.

6.5

Adjustment of Conversion Price

(a)

If and whenever at any time prior to the Time of Expiry the Corporation shall (i) subdivide or redivide the outstanding Common Shares into a greater number of shares, (ii) reduce, combine or consolidate the outstanding Common Shares into a smaller number of shares, or (iii) issue Common Shares to the holders of all or substantially all of the outstanding Common Shares by way of a dividend or distribution (other than the issue of Common Shares to holders of Common Shares who have elected to receive dividends or distributions in the form of Common Shares in lieu of cash dividends or cash distributions paid in the ordinary course on the Common Shares), the Conversion Price in effect on the effective date of such subdivision, redivision, reduction, combination or consolidation or on the record date for such issue of Common Shares by way of a dividend or distribution, as the case may be, shall in the case of any of the events referred to in (i) and (iii) above be decreased in proportion to the number of outstanding Common Shares resulting from such subdivision, redivision or dividend, or shall, in the case of any of the events referred to in (ii) above, be increased in proportion to the number of outstanding Common Shares resulting from such reduction, combination or consolidation. Such adjustment shall be made successively whenever any event referred to in this Section 6.5(a) shall occur. Any such issue of Common Shares by way of a dividend or distribution shall be deemed to have been made on the record date for the dividend or distribution for the purpose of calculating the number of outstanding Common Shares under subsections (c) and (d) of this Section 6.5.

(b)

If and whenever at any time prior to the Time of Expiry the Corporation shall fix a record date for the payment of a cash dividend or distribution to the holders of all or substantially all of the outstanding Common Shares in respect of any Applicable Period, the Conversion Price shall be adjusted immediately after such record date so that they shall be equal to the price determined by multiplying the Conversion Price in effect on such record date by a fraction, of which the denominator shall be the Current Market Price per Common Share on such record date and of which the numerator shall be the Current Market Price per Common Share on such record date minus the amount in cash per Common Share distributed to holders of Common Shares, provided that the Conversion Price so adjusted is not less than $2.60, which represents the closing trading price of the Common Shares on the Toronto Stock Exchange on July 4, 2016, less the maximum permitted discount pursuant to the policies of the Toronto Stock Exchange. Such adjustment shall be made successively whenever such a record date is fixed. To the extent that any such cash dividend or distribution is not paid, the Conversion Price shall be re-adjusted to the Conversion Price which would then be in effect if such record date had not been fixed.

- 57 -

(c)

If and whenever at any time prior to the Time of Expiry the Corporation shall fix a record date for the issuance of options, rights or warrants to all or substantially all the holders of its outstanding Common Shares entitling them, for a period expiring not more than 45 days after such record date, to subscribe for or purchase Common Shares (or securities convertible into Common Shares) at a price per share (or having a conversion or exchange price per share) less than 95% of the Current Market Price of a Common Share on such record date, the Conversion Price shall be adjusted immediately after such record date so that it shall equal the price determined by multiplying the Conversion Price in effect on such record date by a fraction, of which the numerator shall be the total number of Common Shares outstanding on such record date plus a number of Common Shares equal to the number arrived at by dividing the aggregate price of the total number of additional Common Shares offered for subscription or purchase (or the aggregate conversion or exchange price of the convertible securities so offered) by such Current Market Price per Common Share, and of which the denominator shall be the total number of Common Shares outstanding on such record date plus the total number of additional Common Shares offered for subscription or purchase (or into which the convertible securities so offered are convertible). Such adjustment shall be made successively whenever such a record date is fixed. To the extent that any such options, rights or warrants are not so issued or any such options, rights or warrants are not exercised prior to the expiration thereof, the Conversion Price shall be re-adjusted to the Conversion Price which would then be in effect if such record date had not been fixed or to the Conversion Price which would then be in effect based upon the number of Common Shares (or securities convertible into Common Shares) actually issued upon the exercise of such options, rights or warrants were included in such fraction, as the case may be.

(d)

If and whenever at any time prior to the Time of Expiry, there is a reclassification of the Common Shares or a capital reorganization of the Corporation other than as described in Section 6.5(a) or a consolidation, amalgamation, arrangement, binding share exchange, merger of the Corporation with or into any other Person or other entity or acquisition of the Corporation or other combination pursuant to which the Common Shares are converted into or acquired for cash, securities or other property; or a sale or conveyance of the property and assets of the Corporation as an entirety or substantially as an entirety to any other Person (other than a direct or indirect wholly-owned subsidiary of the Corporation) or other entity or a liquidation, dissolution or winding-up of the Corporation, any holder of a Debenture who has not exercised its right of conversion prior to the effective date of such reclassification, capital reorganization, consolidation, amalgamation, arrangement, merger, share exchange, acquisition, combination, sale or conveyance or liquidation, dissolution or winding-up, upon the exercise of such right thereafter, shall be entitled to receive and shall accept, in lieu of the number of Common Shares then sought to be acquired by it, such amount of cash or the number of shares or other securities or property of the Corporation or of the Person or other entity resulting from such merger, amalgamation, arrangement, acquisition, combination or consolidation, or to which such sale or conveyance may be made or which holders of Common Shares receive pursuant to such liquidation, dissolution or winding-up, as the case may be, that such holder of a

- 58 -

Debenture would have been entitled to receive on such reclassification, capital reorganization, consolidation, amalgamation, arrangement, merger, share exchange, acquisition, combination, sale or conveyance or liquidation, dissolution or winding-up, if, on the record date or the effective date thereof, as the case may be, the holder had been the registered holder of the number of Common Shares sought to be acquired by it and to which it was entitled to acquire upon the exercise of the conversion right. If determined appropriate by the Board of Directors, to give effect to or to evidence the provisions of this Section 6.5(d), the Corporation, its successor, or such purchasing Person or other entity, as the case may be, shall, prior to or contemporaneously with any such reclassification, capital reorganization, consolidation, amalgamation, arrangement, merger, share exchange, acquisition, combination, sale or conveyance or liquidation, dissolution or winding-up, enter into an indenture which shall provide, to the extent possible, for the application of the provisions set forth in this Indenture with respect to the rights and interests thereafter of the holder of Debentures to the end that the provisions set forth in this Indenture shall thereafter correspondingly be made applicable, as nearly as may reasonably be, with respect to any cash, shares or other securities or property to which a holder of Debentures is entitled on the exercise of its acquisition rights thereafter. Any indenture entered into between the Corporation and the Trustees pursuant to the provisions of this Section 6.5(d) shall be a supplemental indenture entered into pursuant to the provisions of Article 16. Any indenture entered into between the Corporation, any successor to the Corporation or such purchasing Person or other entity and the Trustees shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided in this Section 6.5(d) and which shall apply to successive reclassifications, capital reorganizations, amalgamations, consolidations, mergers, share exchanges, acquisitions, combinations, sales or conveyances. For greater certainty, nothing in this Section 6.5(d) shall affect or reduce the requirement for any Person to make a Change of Control Purchase Offer or any payment in connection therewith in accordance with Section 2.5, and notice of any transaction to which this Section 6.5(d) applies shall be given in accordance with Section 6.10.

(e)

If the Corporation shall make a distribution to all or substantially all of the holders of Common Shares of shares in the capital of the Corporation, other than Common Shares, or evidences of indebtedness or other assets of the Corporation, including securities (but excluding (x) any issuance of rights or warrants for which an adjustment was made pursuant to Section 6.5(c), and (y) any dividend or distribution paid exclusively in cash for which an adjustment was made pursuant to Section 6.5(b)) (the “Distributed Securities”), then in each such case (unless the Corporation distributes such Distributed Securities to the holders of Debentures on such dividend or distribution date (as if each holder had converted such Debenture into Common Shares immediately preceding the record date with respect to such distribution)) the Conversion Price in effect immediately preceding the record date fixed for the dividend or distribution shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately preceding such record date by a fraction of which the denominator shall be the five day VWAP for the Common Shares immediately

- 59 -

prior to the record date and of which the numerator shall be the five day VWAP for the Common Shares for the first five trading days that occur immediately following such record date. Such adjustment shall be made successively whenever any such distribution is made and shall become effective five Business Days immediately after the record date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price that would then be in effect if such dividend or distribution had not been declared.

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

(f)

If any issuer bid made by the Corporation or any of its Subsidiaries for all or any portion of Common Shares shall expire, then, if the issuer bid shall require the payment to shareholders of consideration per Common Share having a fair market value (determined as provided below) that exceeds the Current Market Price per Common Share on the last date (the “Expiration Date”) tenders could have been made pursuant to such issuer bid (as it may be amended) (the last time at which such tenders could have been made on the Expiration Date is hereinafter sometimes called the “Expiration Time”), the Conversion Price shall be adjusted

- 60 -

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

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

(g)

In any case in which this Section 6.5 shall require that an adjustment shall become effective immediately after a record date for an event referred to herein, the Corporation may defer, until the occurrence of such event, issuing to the holder of any Debenture converted after such record date and before the occurrence of such event the additional Common Shares issuable upon such conversion by reason of the adjustment required by such event before giving effect to such adjustment; provided, however, that the Corporation shall deliver to such holder an appropriate instrument evidencing such holder’s right to receive such additional Common Shares upon the occurrence of the event requiring such adjustment and the right to receive any distributions made on such additional Common Shares declared in favour of holders of record of Common Shares on and after the Date of

- 61 -

Conversion or such later date as such holder would, but for the provisions of this Section 6.5(f), have become the holder of record of such additional Common Shares pursuant to Section 6.4(b).

(h)

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

(i)

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

(j)

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

(k)

In case the Corporation shall take any action affecting the Common Shares other than action described in this Section 6.5, which in the opinion of the Board of Directors, would materially affect the rights of Debentureholders, the Conversion Price shall be adjusted in such manner and at such time, by action of the Board of Directors, subject to the prior written consent of the Toronto Stock Exchange or such other exchange on which the Debentures are then listed, as the Board of Directors, in their sole discretion may determine to be equitable in the circumstances. Failure of the directors to make such an adjustment shall be conclusive evidence that they have determined that it is equitable to make no adjustment in the circumstances.

(l)

Subject to the prior written consent of the Toronto Stock Exchange or such other exchange on which the Debentures are then listed, no adjustment in the Conversion Price shall be made in respect of any event described in Sections 6.5(a), 6.5(b), 6.5(c), 6.5(e) or 6.5(f) other than the events described in Section 6.5(a)(i) or (a)(ii) if the holders of the Debentures are entitled to participate in such event on the same terms mutatis mutandis as if they had converted their Debentures prior to the effective date or record date, as the case may be, of such event.

(m)

Except as stated above in this Section 6.5, no adjustment will be made in the Conversion Price for any Debentures as a result of the issuance of Common

- 62 -

Shares at less than the Current Market Price for such Common Shares on the date of issuance or the then applicable Conversion Price.

6.6

No Requirement to Issue Fractional Common Shares

The Corporation shall not be required to issue fractional Common Shares upon the conversion of Debentures pursuant to this Article. If more than one Debenture shall be surrendered for conversion at one time by the same holder, the number of whole Common Shares issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of such Debentures to be converted. If any fractional interest in a Common Share would, except for the provisions of this Section, be deliverable upon the conversion of any principal amount of Debentures, the Corporation shall, in lieu of delivering any certificate representing such fractional interest, make a cash payment to the holder of such Debenture of an amount equal to the fractional interest which would have been issuable multiplied by the Current Market Price, provided, however, that the Corporation shall not be required to make any payment of less than $5.00.

6.7

Corporation to Reserve Common Shares

The Corporation covenants with the Trustees 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 6 provided, and conditionally allot to Debentureholders who may exercise their conversion rights hereunder, such number of Common Shares as shall then be issuable upon the conversion of all outstanding Debentures. The Corporation covenants with the Trustees that all Common Shares which shall be so issuable shall be duly and validly issued as fully-paid and non-assessable.

6.8

Cancellation of Converted Debentures

Subject to the provisions of Section 6.4 as to Debentures converted in part, all Debentures converted in whole or in part under the provisions of this Article 6 shall be forthwith delivered to and cancelled by the Trustees and no Debenture shall be issued in substitution for those converted.

6.9

Certificate as to Adjustment

The Corporation shall from time to time immediately after the occurrence of any event which requires an adjustment or readjustment as provided in Section 6.5, deliver an Officers’ Certificate to the Trustees specifying the nature of the event requiring the same and the amount of the adjustment necessitated thereby and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based, which certificate and the amount of the adjustment specified therein shall be verified by an opinion of a firm of nationally recognized chartered accountants appointed by the Corporation and acceptable to the Trustees (who may be the Auditors of the Corporation) and shall be conclusive and binding on all parties in interest. When so approved, the Corporation shall, except in respect of any subdivision, redivision, reduction, combination or consolidation of the Common Shares, forthwith give notice to the Debentureholders in the manner provided in Section 14.2 specifying the event requiring such adjustment or readjustment and the results thereof, including the resulting Conversion Price; provided that, if the Corporation has given notice under this Section 6.9 covering all the relevant

- 63 -

facts in respect of such event and if the Trustees approve, no such notice need be given under this Section 6.9.

6.10

Notice of Special Matters

The Corporation covenants with the Trustees that so long as any Debenture remains outstanding, it will give notice to the Trustees, and to the Debentureholders in the manner provided in Section 14.2, of its intention to fix a record date for any event referred to in Sections 6.5(a), 6.5(b), 6.5(c) or 6.5(e) (other than the subdivision, redivision, reduction, combination or consolidation of its Common Shares) which may give rise to an adjustment in the Conversion Price, and, in each case, such notice shall specify the particulars of such event and the record date and the effective date for such event; provided that the Corporation shall only be required to specify in such notice such particulars of such event as shall have been fixed and determined on the date on which such notice is given. Such notice shall be given not less than 14 days in each case prior to such applicable record date.

In addition, the Corporation covenants with the Trustees that so long as any Debenture remains outstanding, it will give notice to the Trustees, and to the Debentureholders in the manner provided in Section 14.2, at least 30 days prior to the effective date of any transaction referred to in Section 6.5(d) stating the consideration into which the Debentures will be convertible after the effective date of such transaction.

6.11

Protection of Trustees

Subject to Section 15.1(d), the Trustees:

(a)

shall not at any time be under any duty or responsibility to any Debentureholder to determine whether any facts exist which may require any adjustment in the Conversion Price, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed in making the same;

(b)

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

(c)

shall not be responsible for any failure of the Corporation to make any cash payment or to issue, transfer or deliver Common Shares or share certificates upon the surrender of any Debenture for the purpose of conversion, or to comply with any of the covenants contained in this Article 6.

6.12

U.S. Securities Laws

Any conversion of Debentures into Common Shares or other securities of the Corporation shall be effected in accordance with U.S. Securities Laws.

- 64 -

7.3

To Give Notice of Default

The Corporation shall notify the Trustees immediately upon obtaining knowledge of any default or Event of Default hereunder, and in any event within 30 days after the Corporation becomes aware or should reasonably become aware of the occurrence of a default or Event of Default hereunder, an Officers’ Certificate setting forth the details of the default, and the action which the Corporation proposes to take with respect thereto.

If the Corporation shall fail to perform any of its covenants contained in this Indenture, the Trustees may notify the Debentureholders of such failure on the part of the Corporation or may itself perform any of the covenants capable of being performed by it, but shall be under no obligation to do so or to notify the Debentureholders. All sums so expended or advanced by the Trustees shall be repayable as provided in Section 7.2. No such performance, expenditure or advance by the Trustees shall be deemed to relieve the Corporation of any default hereunder.

then: (x) in each and every such event listed above, the Trustees may, in their discretion, and shall, upon receipt of a request in writing signed by the holders of not less than 25% in principal amount of the Debentures then outstanding, subject to the provisions of Section 8.3, by notice in writing to the Corporation declare the principal of and interest and premium, if any, on all Debentures then outstanding and all other monies outstanding hereunder to be due and payable and the same shall thereupon forthwith become immediately due and payable to the Trustees, and on the occurrence of an Event of Default under Sections 8.1(e), 8.1(f), 8.1(g) or 8.1(h), the principal of and interest and premium, if any, on all Debentures then outstanding hereunder and all other monies outstanding hereunder, shall automatically without any declaration or other act on the part of the Trustees or any Debentureholder become immediately due and payable to the Trustees and, in either case, upon such amounts becoming due and payable in either (x) or (y) above, the Corporation shall forthwith pay to the Trustees for the benefit of the Debentureholders such principal, accrued and unpaid interest and premium, if any, and interest on amounts in default on such Debenture and all other monies outstanding hereunder, together with subsequent interest at the rate borne by the Debentures on such principal, interest, premium and such other monies from the date of such declaration or event until payment is received by the Trustees, such subsequent interest to be payable at the times and places and in the manner mentioned in and according to the tenor of the Debentures. Such payment when made shall be deemed to have been made in discharge of the Corporation’s obligations hereunder and any monies so received by the Trustees shall be applied in the manner provided in Section 8.6.

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

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

Notice of Events of Default

If an Event of Default shall occur and be continuing the Trustees shall, within 30 days after it receives written notice of the occurrence of such Event of Default, give notice of such Event of Default to the Debentureholders in the manner provided in Section 14.2, provided that notwithstanding the foregoing, unless the Trustees shall have been requested to do so by the holders of at least 25% of the principal amount of the Debentures then outstanding, the Trustees shall not be required to give such notice if the Trustees in good faith shall have determined that the withholding of such notice is in the best interests of the Debentureholders and shall have so advised the Corporation in writing. Notice to holders under this Section 8.2 will be given in the manner and to the extent provided in Section 313(c) of the Trust Indenture Act.

8.4

Enforcement by the Trustee

Subject to the provisions of Section 8.3 and to the provisions of any Extraordinary Resolution that may be passed by the Debentureholders, if the Corporation shall fail to pay to the Trustees, forthwith after the same shall have been declared to be due and payable under Section 8.1, the principal of and premium (if any) and interest on all Debentures then outstanding, together with any other amounts due hereunder, the Trustees may in their discretion and shall upon receipt of a request in writing signed by the holders of not less than 25% in principal amount of the Debentures then outstanding and upon being funded and indemnified to its reasonable satisfaction against all costs, expenses and liabilities to be incurred, proceed in their names as Trustees hereunder to obtain or enforce payment of such principal of and premium (if any) and interest on all the Debentures then outstanding together with any other amounts due hereunder by such proceedings authorized by this Indenture or by law or equity as the Trustees in such request shall have been directed to take, or if such request contains no such direction, or if the Trustees shall act without such request, then by such proceedings authorized by this Indenture or by suit at law or in equity as the Trustees shall deem expedient.

The Trustees shall be entitled and empowered, either in their own names or as trustees 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 Trustees (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustees, their agents and counsel, and any other amounts due the Trustees under Section 15.9) and of the holders of the Debentures allowed in any insolvency, bankruptcy, liquidation or other judicial proceedings relative to the Corporation or its creditors or relative to or affecting its property. The Trustees are 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 Trustees) the true and lawful attorneys-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

- 69 -

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 Trustees, in order to have the respective claims of the Trustees and of the holders of the Debentures against the Corporation or its property allowed in any such proceeding, and to receive payment of or on account of such claims; provided, however, that subject to Section 8.3, nothing contained in this Indenture shall be deemed to give to the Trustees, 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.

The Trustees 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.

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

8.5

No Suits by Debentureholders

No holder of any Debenture shall have any right to institute any action, suit or proceeding at law or in equity for the purpose of enforcing payment of the principal of or interest on the Debentures or for the execution of any trust or power hereunder or for the appointment of a liquidator or receiver or for a receiving order under the Bankruptcy and Insolvency Act (Canada) or to have the Corporation wound up or to file or prove a claim in any liquidation or bankruptcy proceeding or for any other remedy hereunder, unless: (a) such holder shall previously have given to the Trustees written notice of the happening of an Event of Default hereunder; and (b) the Debentureholders by Extraordinary Resolution or by written instrument signed by the holders of at least 25% in principal amount of the Debentures then outstanding shall have made a request to the Trustees and the Trustees shall have been afforded reasonable opportunity to proceed to exercise the powers hereinbefore granted or to institute an action, suit or proceeding in its name for such purpose; and (c) the Debentureholders or any of them shall have furnished to the Trustees, when so requested by the Trustees, sufficient funds and security and indemnity satisfactory to it against the costs, expenses and liabilities to be incurred therein or thereby; and (d) the Trustees shall have failed to act within a 60 days after such notification, request, receipt of sufficient funds, security and offer of indemnity and such notification, request, receipt of sufficient funds, security and offer of indemnity are hereby declared in every such case, at the option of the Trustees, to be conditions precedent to any such proceeding or for any other remedy hereunder by or on behalf of the holder of any Debentures and (e) the holders of more than 50% in aggregate principal amount of the Outstanding Debentures do not give the Trustees a direction that, in the opinion of the Trustees, is inconsistent with the request within such 60-day period.

- 70 -

For purposes of Section 8.4 of this Indenture and this Section 8.6, the Trustees shall comply with Section 316(a) of the Trust Indenture Act in making any determination of whether the holders of the required aggregate principal amount of Outstanding Debentures of a particular series have concurred in any request or direction of the Trustees to pursue any remedy available to the Trustees or the holders with respect to this Indenture or the Debentures of that series or otherwise under the law.

A holder may not use this Indenture to prejudice the rights of another holder of Debentures of the same series or to obtain a preference or priority over such other holder (it being understood that the Trustees do not have any affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such holders).

8.6

Application of Monies by Trustees

(a)

Except as herein otherwise expressly provided, any monies received by the Trustees from the Corporation pursuant to this Article 8, or as a result of legal or other proceedings or from any trustee in bankruptcy or liquidator of the Corporation, shall be applied, together with any other monies in the hands of the Trustees available for such purpose, as follows:

(i)

first, in payment or in reimbursement to the Trustees of their compensation, costs, charges, expenses, borrowings, advances or other monies furnished or provided by or at the instance of the Trustees in or about the execution of their trusts under, or otherwise in relation to, this Indenture (including but not limited to Section 15.9), with interest thereon as herein provided;

(ii)

second, but subject as hereinafter in this Section 8.6 provided, in payment, rateably and proportionately to the holders of Debentures, of the principal of and premium (if any) and accrued and unpaid interest and interest on amounts in default on the Debentures which shall then be outstanding in the priority of principal first and then premium and then accrued and unpaid interest and interest on amounts in default unless otherwise directed by Extraordinary Resolution and in that case in such order or priority as between principal, premium (if any) and interest as may be directed by such resolution; and

(iii)

third, in payment of the surplus, if any, of such monies to the Corporation or its assigns;

provided, however, that no payment shall be made pursuant to clause (ii) above in respect of the principal, premium, if any, or interest on any Debenture held, directly or indirectly, by or for the benefit of the Corporation or any Subsidiary (other than any Debenture pledged for value and in good faith to a Person other than the Corporation 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, premium (if any) and interest (if any) on all Debentures which are not so held.

- 71 -

(b)

The Trustees shall not be bound to apply or make any partial or interim payment of any monies coming into their hands if the amount so received by them, after reserving thereout such amount as the Trustees may think necessary to provide for the payments mentioned in Section 8.6(a), is insufficient to make a distribution of at least 2% of the aggregate principal amount of the outstanding Debentures, but it may retain the money so received by it and invest or deposit the same as provided in Section 15.10 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.

8.7

Control by Majority

The holders of a majority in aggregate principal amount of the outstanding Debentures may direct the time, method and place of conducting any proceeding for any remedy available to the Trustees or exercising any trust or power conferred on the Trustees. However, the Trustees may refuse to follow any direction that conflicts with law or the Indenture, that may involve the Trustees in personal liability, or that the Trustees determine in good faith may be unduly prejudicial to the rights of holders of Debentures not joining in the giving of such direction, and may take any other action it deems proper that is not inconsistent with any such direction received from holders of Debentures.

8.8

Notice of Payment by Trustees

Not less than 15 days’ notice shall be given in the manner provided in Section 14.2 by the Trustees to the Debentureholders of any payment to be made under this Article 8. Such notice shall state the time when and place where such payment is to be made and also the liability under this Indenture to which it is to be applied. After the day so fixed, unless payment shall have been duly demanded and have been refused, the Debentureholders will be entitled to interest only on the balance (if any) of the principal monies, premium (if any) and interest due (if any) to them, respectively, on the Debentures, after deduction of the respective amounts payable in respect thereof on the day so fixed.

8.9

Trustees May Demand Production of Debentures

The Trustees shall have the right to demand production of the Debentures in respect of which any payment of principal, interest or premium required by this Article 8 is made and may cause to be endorsed on the same a memorandum of the amount so paid and the date of payment, but the Trustees may, in their discretion, dispense with such production and endorsement, upon such indemnity being given to it and to the Corporation as the Trustees shall deem sufficient.

8.10

Remedies Cumulative

No remedy herein conferred upon or reserved to the Trustees, 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.

The Corporation covenants and agrees with the Trustees that, in case of any judicial or other proceedings to enforce the rights of the Debentureholders, judgment may be rendered against it in favour of the Debentureholders or in favour of the Trustees as trustees for the Debentureholders for any amount which may remain due in respect of the Debentures and premium (if any) and the interest thereon and any other monies owing hereunder.

8.12

Immunity of Directors, Officers and Others

The Debentureholders and the Trustees hereby waive and release any right, cause of action or remedy now or hereafter existing in any jurisdiction against any past, present or future officer, director or employee of the Corporation or holder of Common Shares of the Corporation or of any successor for the payment of the principal of or premium or interest on any of the Debentures or on any covenant, agreement, representation or warranty by the Corporation contained herein or in the Debentures.

The Trustees shall inform the Corporation promptly following receipt of any bid or bids for Common Shares solicited pursuant to the Common Share Bid Requests. The Trustees shall accept such bid or bids as the Corporation, in its absolute discretion, shall direct by Written Direction of the Corporation, provided that the aggregate proceeds of all sales of Common Shares resulting from the acceptance of such bids, together with the amount of any cash payment by the Corporation in lieu of any fractional Common Shares, on the Common Share Delivery Date, must be equal to the related Common Share Interest Payment Election Amount in connection with any bids so accepted, the Corporation, the Trustees (if required by the Corporation in its absolute discretion) and the applicable bidders shall, not later than the Common Share Delivery Date, enter into Common Share Purchase Agreements and shall comply with all Applicable Securities Legislation and U.S. Securities Laws, including the securities rules and regulations of any stock exchange on which the Debentures or Common Shares are then listed. The Corporation shall pay all fees and expenses in connection with the Common Share Purchase Agreements including the fees and commissions charged by the investment banks, brokers and dealers and the fees of the Trustees.

(g)

Provided that: (i) all conditions specified in each Common Share Purchase Agreement to the closing of all sales thereunder have been satisfied, other than the delivery of the Common Shares to be sold thereunder against payment of the purchase price thereof; and (ii) the purchasers under each Common Share Purchase Agreement shall be ready, willing and able to perform thereunder, in each case on the Common Share Delivery Date, the Corporation shall, on the

- 79 -

Common Share Delivery Date, deliver to the Trustees the Common Shares to be sold on such date, an amount in cash equal to the value of any fractional Common Shares and an Officers’ Certificate to the effect that all conditions precedent to such sales, including those set forth in this Indenture and in each Common Share Purchase Agreement, have been satisfied. Upon such deliveries, the Trustees shall consummate such sales on such Common Share Delivery Date by the delivery of the Common Shares to such purchasers against payment to the Trustees in immediately available funds of the purchase price therefor in an aggregate amount equal to the Common Share Interest Payment Election Amount (less any amount attributable to any fractional Common Shares), whereupon the sole right of a holder of Debentures to receive such holder’s portion of the Common Share Interest Payment Election Amount will be to receive same from the Trustees out of the proceeds of such sales of Common Shares plus any amount received by the Trustees from the Corporation attributable to any fractional Common Shares in full satisfaction of the Interest Obligation and the holder will have no further recourse to the Corporation in respect of the Interest Obligation.

(h)

The Trustees shall, on the Common Share Delivery Date, use the sale proceeds of the Common Shares (together with any cash received from the Corporation in lieu of any fractional Common Shares) to purchase, on the direction of the Corporation in writing, Government Obligations which mature prior to the applicable Interest Payment Date and which the Trustees are required to hold until maturity (the “Common Share Proceeds Investment”) and shall, on such date, deposit the balance, if any, of such sale proceeds in an account established by the Corporation (and which shall be maintained by and subject to the control of the Trustees) (the “Interest Account”) for such Debentures. The Trustees shall hold such Common Share Proceeds Investment (but not income earned thereon) under its exclusive control in an irrevocable trust for the benefit of the holders of the Debentures. At least one Business Day prior to the Interest Payment Date, the Trustees shall deposit amounts from the proceeds of the Common Share Proceeds Investment in the Interest Account to bring the balance of the Interest Account to the Common Share Interest Payment Election Amount. On the Interest Payment Date, the Trustees shall pay the funds held in the Interest Account to the holders of record of the Debentures on the Interest Payment Date and, provided that there is no Event of Default, shall remit amounts, if any, in respect of income earned on the Common Share Proceeds Investment or otherwise in excess of the Common Share Interest Payment Election Amount to the Corporation.

(i)

Neither the making of a Common Share Payment Election nor the consummation of sales of Common Shares on a Common Share Delivery Date shall (i) result in the holders of the Debentures not being entitled to receive on the applicable Interest Payment Date cash in an aggregate amount equal to the Interest Obligation payable on such date or (ii) entitle such holders to receive any Common Shares in satisfaction of such Interest Obligation.

(j)

No fractional Common Shares will be issued in satisfaction of interest but in lieu thereof the Corporation will satisfy such fractional interest by a cash payment

- 80 -

equal to the market price of such fractional interest provided, however, that the Corporation shall not be required to make any payment of less than $5.00.

The Trustees may at any time and from time to time, and the Trustees shall, on receipt of a Written Direction of the Corporation or a written request signed by the holders of not less than 25% of the principal amount of the Debentures then outstanding and upon receiving funding and being indemnified to their reasonable satisfaction by the Corporation or by the Debentureholders signing such request against the costs which may be incurred in connection with the calling and holding of such meeting, convene a meeting of the Debentureholders. In the event of the Trustees failing, within 30 days after receipt of any such request and such funding of indemnity, to give notice convening a meeting, the Corporation or such Debentureholders, as the case may be, may convene such meeting. Every such meeting shall be held in Toronto, Ontario or Denver, Colorado or at such other place as may be approved or determined by the Trustees, the Corporation or such Debentureholders as convened in accordance with this Section 13.1.

At least 21 days’ notice of any meeting shall be given to the Debentureholders in the manner provided in Section 14.2 and a copy of such notice shall be sent by post to the Trustees (unless the meeting has been called by them) and the Issuer (unless the meeting has been called by it). Such notice shall state the time when and the place where the meeting is to be held and shall state briefly the general nature of the business to be transacted thereat and it shall not be necessary for any such notice to set out the terms of any resolution to be proposed or any of the provisions of this Article. The accidental omission to give notice of a meeting to any holder of Debentures shall not invalidate any resolution passed at any such meeting. A holder may waive notice of a meeting either before or after the meeting.

(b)

If the business to be transacted at any meeting by Extraordinary Resolution or otherwise, or any action to be taken or power exercised by instrument in writing under Section 13.16, especially affects the rights of holders of Debentures of one or more series in a manner or to an extent differing in any material way from that

- 85 -

in or to which the rights of holders of Debentures of any other series are affected (determined as provided in Sections 13.2(c) and (d)), then:

(i)

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

(ii)

the holders of Debentures of an especially affected series shall not be bound by any action taken at a Serial Meeting or by instrument in writing under Section 13.16 unless in addition to compliance with the other provisions of this Article 13:

(A)

at such Serial Meeting: (I) there are Debentureholders present in Person or by proxy and representing at least 25% in principal amount of the Debentures then outstanding of such series, subject to the provisions of this Article 13 as to quorum at adjourned meetings; and (II) the resolution is passed by the affirmative vote of the holders of more than 50% (or in the case of an Extraordinary Resolution not less than 66-2/3%) of the principal amount of the Debentures of such series then outstanding voted on the resolution; or

(B)

in the case of action taken or power exercised by instrument in writing under Section 13.16, such instrument is signed in one or more counterparts by the holders of not less than 66-2/3% in principal amount of the Debentures of such series then outstanding.

Subject to Section 13.2(d), the determination as to whether any business to be transacted at a meeting of Debentureholders, or any action to be taken or power to be exercised by instrument in writing under Section 13.16, especially affects the rights of the Debentureholders of one or more series in a manner or to an extent differing in any material way from that in or to which it affects the rights of Debentureholders of any other series (and is therefore an especially affected series) shall be determined by an opinion of Counsel, which shall be binding on all Debentureholders, the Trustees and the Corporation for all purposes hereof.

(d)

A proposal:

(i)

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

(ii)

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

(iii)

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

- 86 -

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.

13.3

Chairman

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

13.4

Quorum

Subject to the provisions of Section 13.12, at any meeting of the Debentureholders a quorum shall consist of Debentureholders present in Person or by proxy and representing at least 25% in principal amount of the outstanding Debentures and, if the meeting is a Serial Meeting, at least 25% of the Debentures then outstanding of each especially affected series. If a quorum of the Debentureholders shall not be present within 30 minutes from the time fixed for holding any meeting, the meeting, if summoned by the Debentureholders or pursuant to a request of the Debentureholders, shall be dissolved, but in any other case the meeting shall be adjourned to the same day in the next week (unless such day is not a Business Day in which case it shall be adjourned to the next following Business Day thereafter) at the same time and place and no notice shall be required to be given in respect of such adjourned meeting. At the adjourned meeting, the Debentureholders present in Person or by proxy shall, subject to the provisions of Section 13.12, constitute a quorum and may transact the business for which the meeting was originally convened notwithstanding that they may not represent 25% of the principal amount of the outstanding Debentures or of the Debentures then outstanding of each especially affected series. Any business may be brought before or dealt with at an adjourned meeting which might have been brought before or dealt with at the original meeting in accordance with the notice calling the same. No business shall be transacted at any meeting unless the required quorum be present at the commencement of business.

13.5

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.

13.6

Show of Hands

Every question submitted to a meeting shall, subject to Section 13.7, 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.

- 87 -

13.7

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.

13.8

Voting

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

13.9

Proxies

A Debentureholder may be present and vote at any meeting of Debentureholders by an authorized representative. The Trustees, or the Corporation with the approval of the Trustees, 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 Trustees, the Corporation 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;

(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, cabled, telegraphed or

- 88 -

sent by other electronic means before the meeting to the Corporation or to the Trustees 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; and

(d)

generally for the calling of a meeting of Holders and the conduct of business thereat.

Any regulations so made shall be binding and effective and the votes given in accordance therewith shall be valid and shall be counted. Save as such regulations may provide, the only Persons who shall be recognized at any meeting as 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.

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, the filling of vacancies occurring in its number and its procedure generally. Such regulations may provide that the committee may act at a meeting at which a quorum is present or may act by minutes signed by the number of members thereof necessary to constitute a quorum.

FLOATING RATE CONVERTIBLE UNSECURED SUBORDINATED DEBENTURES

ENERGY FUELS INC. (the “Corporation” or the “Issuer”) for value received hereby acknowledges itself indebted and, subject to the provisions of the Amended and Restated Convertible Debenture Indenture (the “Indenture”) dated as of among the Corporation, BNY Trust Company of Canada (the “Canadian Trustee”) and The Bank of New York Mellon (the “U.S. Trustee”), promises to pay to the registered holder hereof on December 31, 2020 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 Canada on presentation and surrender of this Initial Debenture at the principal office of the Trustees in accordance with the terms of the Indenture and, subject as hereinafter provided, to pay interest on the principal amount hereof from the date hereof, or from the last Interest Payment Date to which interest shall have been paid or made available for payment hereon, whichever is later, at the Applicable Rate (based on a 365 day year and the actual number of days elapsed in that period), in like money, in arrears in semi-annual installments on June 30 and December 31 in each year commencing on December 31, 2012 and the last payment (representing interest payable from the last Interest Payment Date to, but excluding, the Maturity Date) to fall due on the Maturity Date and, should the Corporation at any time make default in the payment of any principal, premium, if any, or interest, to pay interest on the amount in default at the same rate, in like money and on the same dates. For certainty, the first interest payment will include interest accrued from to, but excluding December 31, 2016. For the purposes of disclosure under the Interest Act (Canada), whenever interest is

A-1

computed under this Initial Debenture 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 by multiplying such rate of interest by the actual number of days in such calendar year of calculation and dividing it by the number of days in the deemed year.

This Initial Debenture is one of the Floating-Rate Convertible Unsecured Subordinated Debentures (referred to herein as the “Initial Debentures”) of the Corporation issued or issuable in one or more series under the provisions of the Indenture. The Initial Debentures authorized for issue immediately are limited to an aggregate principal amount of $22,000,000 in lawful money of Canada. Reference is hereby expressly made to the Indenture for a description of the terms and conditions upon which the Initial Debentures are or are to be issued and held and the rights and remedies of the holders of the Initial Debentures and of the Corporation and of the Trustees, all to the same effect as if the provisions of the Indenture were herein set forth to all of which provisions the holder of this Initial Debenture by acceptance hereof assents.

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

Any part, being $1,000 or an integral multiple thereof, of the principal of this Initial Debenture, provided that the principal amount of this Initial Debenture is in a denomination in excess of $1,000, is convertible, at the option of the holder hereof, upon surrender of this Initial Debenture at the principal office of the Trustees, at any time prior to the close of business on the Business Day immediately preceding the Maturity Date or, if this Initial Debenture is called for redemption on or prior to such date, then, to the extent so called for redemption, up to but not after the close of business on the fifth Business Day immediately preceding the date specified for redemption of this Initial Debenture, into Common Shares (without adjustment for interest accrued hereon or for dividends or distributions on Common Shares issuable upon conversion) at a conversion price of $4.15 (the “Conversion Price”) per Common Share, being a rate of approximately 240.96 Common Shares for each $1,000 principal amount of Initial Debentures, all subject to the terms and conditions and in the manner set forth in the Indenture. No Initial Debentures may be converted during the five Business Days preceding and including June 30 and December 31 in each year, commencing December 31, 2016, as the registers of the Canadian Trustee will be closed during such periods. The Indenture makes provision for the adjustment of the Conversion Price in the events therein specified. No fractional Common Shares will be issued on any conversion but in lieu thereof, the Corporation will satisfy such fractional interest by a cash payment equal to the Current Market Price of such fractional interest determined in accordance with the Indenture. Holders converting Debentures shall receive accrued and unpaid interest thereon from the period of the last Interest Payment Date prior to the Date of Conversion to the date that is one Business Day prior to the Date of Conversion. If a Debenture is surrendered for conversion on an Interest Payment Date or during the five preceding Business Days, the Person or Persons entitled to receive Common Shares in respect of the Debentures so surrendered for conversion shall not become the holder or holders of record of such Common Shares until the Business Day following such Interest Payment Date.

At any time prior to the Maturity Date of the Initial Debentures, provided that the Current Market Price of the Common Shares of the Corporation is at least 125% of the Conversion Price of the Initial Debentures, the Initial Debentures are redeemable at the option of the Corporation in whole or in part from time to time at a Redemption Price equal to 100% (expressed as a percentage of their principal amount) plus accrued and unpaid interest and otherwise on the terms and conditions described in the Indenture. In connection with the redemption of the Initial Debentures pursuant to this paragraph, the Corporation may, on notice as provided in the Indenture, at its option and subject to any applicable regulatory approval, elect to satisfy its obligation to pay all or any portion of the applicable Redemption Price by the issue of that number of Common Shares obtained by dividing the applicable Redemption Price by 95% of the volume

A-2

weighted average trading price of the Common Shares on the Toronto Stock Exchange or such other stock exchange on which the Initial Debentures may be listed for the 20 consecutive trading days ending five trading days before the Redemption Date.

In addition, at any time after June 30, 2019 and prior to the Maturity Date of the Initial Debentures, the Initial Debentures are redeemable at the option of the Corporation in whole or in part from time to time at a Redemption Price equal to 101% (expressed as a percentage of their principal amount) plus accrued and unpaid interest thereon up to (but excluding) the Redemption Date. Notwithstanding anything in this Debenture or in the Indenture to the contrary (including any provision of Section 4.6 of the Indenture), in connection with the redemption of the Initial Debentures pursuant to this paragraph, the Redemption Price shall be paid in cash.

Upon the occurrence of a Change of Control of the Corporation, the Corporation is required to make an offer to purchase all of the Initial Debentures at a price equal to 100% of the principal amount of such Initial Debentures plus accrued and unpaid interest (if any) up to, but excluding, the date the Initial Debentures are so repurchased (the “Change of Control Purchase Offer”). If 90% or more of the principal amount of all Debentures outstanding on the date the Corporation provides notice of a Change of Control to the Trustees have been tendered for purchase pursuant to the Change of Control Purchase Offer, the Corporation has the right to redeem all the remaining outstanding Initial Debentures on the same date and at the same price.

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

The Corporation may, on notice as provided in the Indenture, at its option and subject to any applicable regulatory or stock exchange approval, elect to satisfy the obligation to repay all or any portion of the principal amount of this Initial Debenture due on the Maturity Date by the issue of that number of Freely Tradeable Common Shares obtained by dividing the principal amount of this Initial Debenture (or that portion to be paid for in Common Shares pursuant to the exercise by the Corporation of the Common Share Repayment Right), by 95% of the volume weighted average trading price of the Common Shares on the Toronto Stock Exchange or other stock exchange on which the Debentures may be listed for the 20 consecutive trading days ending five trading days before the Maturity Date, provided that all accrued and unpaid interest thereon shall be payable to the holder in cash.

Each holder of Initial Debentures shall have a right (the “Put Right”) to require the Corporation to purchase up to 20% of the Initial Debentures held by such holder on June 30, 2017 at a price equal to 100% of the principal amount thereof plus accrued and unpaid interest (less any tax required by law to be deducted) on such Initial Debentures up to, but excluding, the Put Date and subject to the terms and conditions of the Indenture.

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

The principal hereof may become or be declared due and payable before the stated maturity in the events, in the manner, with the effect and at the times provided in the Indenture.

A-3

Any payments made by or on behalf of the Corporation under or with respect to the Debentures (including for greater certainty and without limitation, the delivery of Common Shares or other property in connection with the conversion or redemption of Debentures) will be made free and clear of and without withholding or deduction for or on account of any Canadian Taxes, unless the Corporation or any other Payor is required to withhold or deduct Canadian Taxes by applicable law or by the interpretation or administration thereof by the relevant governmental authority. If the Corporation is so required to withhold or deduct any amount for or on account of Canadian Taxes from any payment made under or with respect to the Debentures, the Corporation will cause the Payor to make such withholding or deduction and will remit the full amount withheld or deducted to the relevant governmental authority as and when required by applicable law and the Corporation will pay such Additional Amounts as may be necessary so that the net amount received by each Debentureholder that is a non-resident of Canada (“Non-Resident Holder”) after such withholding or deduction will not be less than the amount such Non-Resident Holder would have received if such Canadian Taxes had not been withheld or deducted, provided, however, that no Additional Amounts will be payable with respect to any payment to an Excluded Holder.

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 percentage of Debentures outstanding (or specific series), which resolutions or instruments may have the effect of amending the terms of this Initial Debenture or the Indenture.

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

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

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

To the extent that the terms and conditions stated in this Debenture conflict with the terms and conditions of the Indenture, the latter shall prevail.

Capitalized words or expressions used in this Initial Debenture shall, unless otherwise defined herein, have the meaning ascribed thereto in the Indenture.
