2.4

Form and Terms of Initial Debentures

(a)

The first series of Debentures (the "Initial Debentures") authorized for issue immediately is limited to an aggregate principal amount of up to $57,500,000 with $50,000,000 to be issued upon the execution hereof with a further principal amount of $7,500,000 issuable when, and if, the Over-Allotment Option is exercised. The Initial Debentures shall be designated as "6.75% Extendible Convertible Unsecured Subordinated Debentures".

(b)

The Initial Debentures shall be dated as at the date of the initial closing of the Initial Debenture Offering, regardless of the actual date of issue, and shall mature on the Initial Maturity Date; provided that if the Disposition Closing occurs prior to the Termination Time, the maturity date of the Initial Debentures will automatically be extended to the Final Maturity Date.

(c)

The Initial Debentures shall bear interest from the date of the Initial Debentures at the rate of 6.75% per annum, payable semi-annually in arrears on September 30 and March 31 in each year (computed on the basis of a 365-day year and payable in equal semi-annual amounts; except that interest in respect of any period that is longer or shorter than a full semi-annual interest period will be computed on the basis of a 365 day year and the actual number of days elapsed in the relevant period and will accrue from day to day), the first such payment to fall due on September 30, 2016 (unless the Initial Maturity Date occurs prior to such date in which case the first interest payment shall fall due on the Initial Maturity Date) and, assuming maturity of the Initial Debentures is extended to the Final Maturity Date, the last such payment (representing interest payable from the Interest Payment Date immediately prior to the Final Maturity Date to, but excluding, the Final Maturity Date of the Initial Debentures) to fall due on September 30, 2021, payable after as well as before maturity and after as well as before default, with interest on amounts in default at the same rate, compounded semi-annually. For certainty, the first interest payment will include interest accrued from and including the date of closing of the Initial Debenture Offering to, but excluding, September 30, 2016, which will be equal to $9.62 for each $1,000 principal amount of Initial Debentures; provided that if the Maturity Date of the Initial Debentures is not extended to the Final Maturity Date and the Initial Maturity Date occurs prior to September 30, 2016 the first interest payment will include interest accrued from the closing of the Initial Debenture Offering to, but excluding, the Initial Maturity Date. Any payment required to be made on any day that is not a Business Day will be made on the next succeeding Business Day. The record dates for the payment of interest on the Initial Debentures will be March 15 and September 15 in each year (or the first Business Day prior to such date if not a Business Day).

(d)

The Initial Debentures will be redeemable in accordance with the terms of Article 4, provided that the Initial Debentures will not be redeemable before September 30, 2019, except in the event of the satisfaction of certain conditions after a Change of Control has occurred as outlined herein. On and after September 30, 2019 and at any time prior to September 30, 2020, provided that the Current Market Price at the time of the Redemption Notice is at least 125% of the Conversion Price, the Initial Debentures may be redeemed at the option of the Corporation in whole or in part from time to time on notice as provided for in Section 4.3 at a Redemption Price equal to their principal amount plus accrued and unpaid interest thereon up to (but excluding) the Redemption Date. On or after September 30, 2020 and prior to the Final Maturity Date, the Initial Debentures may be redeemed by the Corporation, in whole or in part from time to time, at the option of the Corporation on notice as provided for in Section 4.3 at a Redemption Price equal to their principal amount plus accrued and unpaid interest thereon up to (but excluding) the Redemption Date. The Redemption Notice for the Initial Debentures shall be substantially in the form of Schedule "B". In connection with the redemption of the Initial Debentures, the Corporation may, at its option and subject to the provisions of Section 4.6 and subject to regulatory approval, elect to satisfy its obligation to pay all or a portion of the aggregate principal portion of the Redemption Price of the Initial Debentures to be redeemed by issuing and delivering to the holders of such Initial Debentures, such number of Freely Tradeable Common Shares as is obtained by dividing the aggregate principal portion of the Redemption Price by 95% of the Current Market Price in effect on the Redemption Date. If the Corporation elects to exercise such option, it shall so specify and provide details in the Redemption Notice. Any accrued and unpaid interest will be paid in cash.

(e)

The Initial Debentures will be direct, unsecured obligations of the Corporation and will be subordinated to all existing and future Senior Indebtedness of the Corporation in accordance with the provisions of Article 5. In accordance with Section 2.12, the Initial Debentures will rank pari passu with one another and with each other series of Debentures issued under this Indenture or under indentures supplemental to this Indenture (regardless of their actual date or terms of issue) and, except as prescribed by law, with all other existing and future subordinated unsecured indebtedness of the Corporation other than, for certainty, Senior Indebtedness, to the extent that such other existing and future subordinated unsecured indebtedness of the Corporation is subordinated on the same terms.

(f)

Upon and subject to the provisions and conditions of Article 6 and Section 3.6, the holder of each Initial Debenture shall have the right at such holder's option, at any time following the Disposition Closing and prior to 5:00 p.m. (Calgary time) on the earliest of (i) the Business Day immediately preceding the Final Maturity Date; (ii) if the Initial Debentures are called for redemption, on the Business Day immediately preceding the date specified by the Corporation for redemption of the Initial Debentures; (iii) if called for repurchase pursuant to the exercise by the Corporation of the 90% Redemption Right, on the Business Day immediately preceding the payment date; or (iv) if subject to compulsory acquisition as provided for in Article 12, on the Business Day immediately prior to the day on which such acquisition becomes effective, subject to the satisfaction of certain conditions, by notice to the holders of Initial Debentures in accordance with Sections 2.4(d), 4.3 and 12.3, as applicable (the earliest 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 $1.62 such that approximately 617.2840 Common Shares shall be issued for each $1,000 principal amount of Initial Debentures so converted, subject to the terms of Article 6. 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. 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 2.4(k) and Section 6.5.

Holders converting their Initial Debentures will receive, in addition to the applicable number of Common Shares, accrued and unpaid interest (less any taxes required to be deducted) in respect of the Initial Debentures surrendered for conversion up to but excluding the Date of Conversion from, and including, the most recent Interest Payment Date in accordance with Section 6.4(j). For clarity, payment of such interest, whether in cash or by delivery of Freely Tradeable Common Shares pursuant to the exercise of the Common Share Interest Payment Election, may, at the option of the Corporation, be paid on the next regularly scheduled Interest Payment Date following the Date of Conversion.

Holders of Initial Debentures surrendered for conversion during the period from the close of business on any regular record date for the payment of interest on the Initial Debentures to the opening of business on the next succeeding Interest Payment Date will receive the semi-annual interest payable on such Initial Debentures on the corresponding Interest Payment Date notwithstanding the conversion. In the event that a holder of Debentures exercises their conversion right following a Redemption Notice by the Corporation, such holder will be entitled to receive accrued and unpaid interest, in addition to the applicable number of Common Shares to be received on conversion, for the period from the last Interest Payment Date to (but excluding) the Date of Conversion.

The Conversion Price will not be adjusted for accrued interest.

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

A Debenture in respect of which a holder has accepted a notice in respect of a Debenture Offer pursuant to the provisions of Section 2.4(j) may be surrendered for conversion only if such notice is withdrawn in accordance with this Indenture.

(g)

Provided that the maturity of the Initial Debentures is extended to the Final Maturity Date, on redemption or maturity of the Initial Debentures, the Corporation may, at its option and subject to the provisions of Section 4.6 and Section 4.10, as applicable, and subject to regulatory 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 will be paid in cash.

(h)

The Initial Debentures shall be issued in denominations of $1,000 and integral multiples of $1,000 and the Trustee is hereby appointed as registrar and transfer agent for the Initial Debentures at its offices in Calgary, Alberta or Xxxxxxx, Xxxxxxx. Each Initial Debenture issued as a Debenture Certificate and the certificate of the Trustee endorsed thereon shall be issued in substantially the form set out in Schedule "A", with such insertions, omissions, substitutions or other variations as shall be required or permitted by this Indenture, and may have imprinted or otherwise reproduced thereon such legend or legends or endorsements, not inconsistent with the provisions of this Indenture, as may be required to comply with any law or with any rules or regulations pursuant thereto or with any rules or regulations of any securities exchange or securities regulatory authority or to conform with general usage, all as may be determined by the director or officer of the Corporation executing such Initial Debenture in accordance with Section 2.7 hereof, as conclusively evidenced by their execution of an Initial Debenture. Each Initial Debenture issued as a Debenture Certificate shall additionally bear such distinguishing letters and numbers as the Trustee shall approve. Notwithstanding the foregoing, an Initial Debenture may be in such other form or forms as may, from time to time, be approved by a resolution of the Board of Directors, or as specified in an Officers' Certificate. The Initial Debentures may be engraved, lithographed, printed, mimeographed or typewritten or partly in one form and partly in another, including non-certificated electronic form.

The Initial Debentures issued pursuant to the Initial Debenture Offering shall initially be issued as Uncertificated Debentures.

Upon and subject to the provisions of Article 10, the Corporation may elect, from time to time, to satisfy its Interest Obligation on the Initial Debentures on any Interest Payment Date occurring after the Disposition Closing (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 Trustee pursuant to the Common Share Interest Payment Election.

(j)

Within 30 days following the occurrence of a Change of Control, the Corporation shall be obligated to offer to purchase all Initial Debentures then outstanding. The terms and conditions of such obligation (in addition to complying with Applicable Securities Legislation) are set forth below:

(i)

Within 30 days following the occurrence of a Change of Control, the Corporation shall deliver to the Trustee a notice in writing 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 together with a cash offer in writing (the "Debenture Offer") to purchase all (or any portion actually tendered to such offer) of the Initial Debentures then outstanding from the holders thereof at a price per Initial Debenture equal to 100% of the principal amount thereof together with accrued and unpaid interest thereon up to but excluding the Change of Control Purchase Date (as defined below) (the "Offer Price"). The Trustee will promptly thereafter deliver, by prepaid courier or mail, the Debenture Offer to the holders of all Initial Debentures then outstanding, at their addresses appearing in the registers of holders of Initial Debentures maintained by the Trustee.

(ii)

The Debenture Offer shall specify the date (the "Expiry Date") and time (the "Expiry Time") on which the Debenture Offer shall expire which date and time shall not, unless otherwise required by Applicable Securities Legislation, be earlier than the close of business on the 35th day and not later than the close of business on the 60th day following the date on which such Debenture Offer is made.

(iii)

The Debenture Offer shall specify that the Debenture Offer may be accepted by the holders of Initial Debentures by tendering the Initial Debentures so held by them to the Trustee at its offices in Calgary, Alberta or Toronto, Ontario at or before the Expiry Time together with an acceptance notice (the "Acceptance Notice") in form and substance acceptable to the Trustee.

(iv)

The Debenture Offer shall state that holders of Initial Debentures may accept the Debenture Offer in respect of all or a portion (in a minimum amount of $1,000 principal amount and multiples thereof) of their Initial Debentures.

(v)

The Debenture Offer shall specify a date (the "Change of Control Purchase Date") no later than the third Business Day following the Expiry Date on which the Corporation shall take up and pay for all Initial Debentures duly tendered in acceptance of the Debenture Offer.

(vi)

The Corporation shall, on or before 11:00 a.m. (Calgary time), on the Business Day immediately prior to the Change of Control Purchase Date pay to the Trustee by wire transfer or such other means as may be acceptable to the Trustee, an amount of money sufficient to pay the aggregate Offer Price in respect of all Initial Debentures duly tendered to the Debenture Offer (less any tax required by law to be deducted). The Trustee, on behalf of the Corporation, will pay the Offer Price to the holders of Initial Debentures in the respective amounts to which they are entitled in accordance with the Debenture Offer as aforesaid.

(vii)

If holders of 90% or more of the aggregate principal amount of Initial Debentures outstanding on the date the Corporation delivers the Debenture Offer to the Trustee (other than Initial Debentures held at such date by or on behalf of the Corporation, associates or affiliates of the Corporation or anyone acting jointly or in concert with the Corporation) accept the Debenture Offer, the Corporation shall have the right (the "90% Redemption Right"), upon written notice (the "90% Redemption Right Notice") provided to the Trustee within ten Business Days following the Expiry Date, to redeem on the purchase date specified in the 90% Redemption Right Notice all the Initial Debentures remaining outstanding at the Offer Price and on the other terms and conditions provided herein. Upon receipt of such notice by the Trustee, the Trustee shall promptly provide written notice to each holder of outstanding Initial Debentures (other than those that have accepted the Debenture Offer) that:

(A)

the Corporation has exercised the 90% Redemption Right and is purchasing all outstanding Initial Debentures effective as at the Change of Control Purchase Date at the Offer Price;

(B)

such holder must surrender its Initial Debentures to the Trustee on the same terms as those holders that accepted the Debenture Offer within ten days after the sending of such notice; and

(C)

the rights of such holder under the terms of the Initial Debentures and this Indenture shall cease to be effective as of the Change of Control Purchase Date provided the Corporation has, on or before the date on which the Corporation delivers the 90% Redemption Right Notice to the Trustee, paid the aggregate Offer Price to, or to the order of, the Trustee and thereafter such holder's Initial Debentures shall not be considered to be outstanding and such holder shall not have any rights hereunder except to receive such Offer Price to which such holder is entitled upon surrender and delivery of such holder's Initial Debentures in accordance with the Indenture.

(viii)

The Corporation shall on or before 11:00 a.m. (Calgary time) on the Business Day immediately prior to the date on which the Corporation delivers the 90% Redemption Right Notice pay to the Trustee by wire transfer or such other means as may be acceptable to the Trustee an amount of money sufficient to pay the aggregate Offer Price in respect of all Initial Debentures to be redeemed pursuant to the 90% Redemption Right (less any tax required by law to be deducted). The Trustee, on behalf of the Corporation, will pay the Offer Price to the holders of Initial Debentures in the respective amounts to which they are entitled in accordance with the exercise of the 90% Redemption Right as aforesaid upon surrender and delivery of such holders' Initial Debentures.

(ix)

The Initial Debentures in respect of which the Corporation has made payment to the Trustee in accordance with the terms of this Section 2.4(j) (or the portion thereof tendered in acceptance of the Debenture Offer) shall thereafter no longer be considered to be outstanding under this Indenture. The Corporation shall also deposit with the Trustee a sum of money sufficient to pay any charges or expenses which may be incurred by the Trustee in connection with the Debenture Offer and the exercise of the 90% Redemption Right, if applicable. All Initial Debentures in respect of which payment of the Offer Price has been so made shall be cancelled by the Trustee.

(x)

In the event only a portion of the principal amount of an Initial Debenture is tendered by a holder thereof in acceptance of the Debenture Offer, the Corporation shall execute and deliver to the Trustee and the Trustee shall certify and deliver to the holder, without charge to such holder, a certificate (if applicable) or such other evidence of ownership representing the principal amount of the Initial Debenture not so tendered in acceptance of the Debenture Offer.

(xi)

Initial Debentures for which holders have accepted the Debenture Offer and Initial Debentures which the Corporation has elected to redeem in accordance with this Section 2.4(j) shall become due and payable at the Offer Price on the Change of Control Purchase Date, in the same manner and with the same effect as if it were the date of maturity specified in such Initial Debentures, anything therein or herein to the contrary notwithstanding, and from and after the Change of Control Purchase Date, if the money necessary to purchase or redeem, or the Common Shares necessary to purchase or redeem, the Initial Debentures shall have been deposited as provided in this Section 2.4(j) and affidavits or other proofs satisfactory to the Trustee as to the publication and/or mailing of such notices shall have been lodged with it, interest on the Initial Debentures shall cease. If any question shall arise as to whether any notice has been given as above provided and such deposit made, such question shall be decided by the Trustee whose decision shall be final and binding upon all parties in interest.

(xii)

In case the holder of any Initial Debenture to be purchased or redeemed in accordance with this Section 2.4(j) 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 such Common Shares issuable in respect thereof, or give such receipt therefor, if any, as the Trustee may require, such monies may be set aside in trust, or such Common Shares may be held in trust, without interest, either in the deposit department of the Trustee or in a chartered bank, and such setting aside shall for all purposes be deemed a payment to the Debentureholder of the sum or the Common Shares so set aside and the Debentureholder shall have no other right except to receive payment of the monies so paid and deposited, or take delivery of the Common Shares so deposited, or both, upon surrender and delivery of such holder's Initial Debenture. In the event that any money or Common Shares required to be deposited hereunder with the Trustee or any depository or paying agent on account of principal, premium, if any, or interest, if any, on Initial Debentures issued hereunder shall remain so deposited for a period of three years less a day from the Change of Control Purchase Date (the "Unclaimed Funds Return Date"), then such monies, or Common Shares, together with any accumulated interest thereon, or any distributions paid thereon, shall at the end of such period be paid over or delivered over by the Trustee or such depository or paying agent to the Corporation and the Trustee shall not be responsible to Debentureholders for any amounts owing to them.

(xiii)

Subject to the provisions above related to Initial Debentures purchased in part, all Initial Debentures redeemed and paid under this Section 2.4(j) shall forthwith be delivered to the Trustee and cancelled and no Initial Debentures shall be issued in substitution therefor.

(k)

In addition to the requirements of Section 2.4(j) in respect of a Change of Control and subject to regulatory approval, the following provisions shall apply in respect of the occurrence of a Cash Change of Control occurring on or before the Final Maturity Date:

(i)

During the period beginning ten trading days before the anticipated date on which the Cash Change of Control becomes effective and ending on the date that is 30 days after the Debenture Offer is delivered to holders of Initial Debentures in accordance with Section 2.4(j)(i) (the "Cash Change of Control Conversion Period"), holders of Initial Debentures will be entitled to convert their Initial Debentures, in whole or in part, and receive, in addition to the number of Common Shares (or cash or other property or securities in substitution therefor) they would otherwise be entitled to receive in accordance with the provisions and conditions of Section 2.4(f) and Article 6, an additional number of Common Shares (or cash or other property or securities in substitution therefor) per $1,000 principal amount of Initial Debentures as set forth in this Section 2.4(k) (the "Make Whole Premium").

(ii)

The number of additional Common Shares per $1,000 principal amount of Initial Debentures constituting the Make Whole Premium (the "Make Whole Premium Shares") will be determined by reference to the table following subsection 2.4(k)(iii) and is based on the date on which the Cash Change of Control becomes effective (the "Effective Date") and the price (the "Cash Offer Price") paid per Common Share in the transaction constituting the Change of Control. If holders of Common Shares receive (or are entitled and able in all circumstances to receive) only cash in the transaction constituting the Change of Control, the Cash Offer Price shall be the cash amount paid per Share. Otherwise, the Cash Offer Price shall be equal to the Current Market Price of the Common Shares on the day immediately preceding the Effective Date; provided that for the purposes of this Section 2.4(k)(ii) and the determination of the Current Market Price, the applicable period shall be calculated based on the 20 consecutive trading days ending five trading days preceding the applicable date. Notwithstanding the foregoing, in no circumstances can the effective Conversion Price (calculated by dividing $1,000 by the number of Common Shares issuable upon conversion, including the maximum number of Make Whole Premium Shares hereunder) be less than the maximum permitted discounted price permitted by the TSX (or such other recognized exchange on which the Debentures are then listed) at the time of announcement of the Initial Debenture Offering, prior to any adjustments that may be made to the Cash Offer Price to correspond to an adjustment to the Conversion Price under this Indenture.

(iii)

The following table shows the number of Make Whole Premium Shares for each hypothetical Cash Offer Price and Effective Date set forth below, expressed as additional Common Shares per $1,000 principal amount of Initial Debentures. For the avoidance of doubt, the Corporation shall not be obliged to pay the Make Whole Premium otherwise than by issuance of the applicable number of Common Shares in excess of the number of Common Shares to which holders would otherwise have been entitled at the Conversion Price (the "Base Shares") upon conversion of the Initial Debentures in accordance with the provisions and conditions of Section 2.4(f) and Article 6.

(iv)

The actual Cash Offer Price and Effective Date may not be set forth on the table above, in which case:

(A)

if the actual Cash Offer Price on the Effective Date is between two Cash Offer Prices on the table and/or the actual Effective Date is between two Effective Dates on the table, the number of Make Whole Premium Shares will be determined by a straight-line interpolation between the Make Whole Premium set forth for the two Cash Offer Prices and/or the two Effective Dates on the table based on a 365-day year, as applicable;

(B)

if the Cash Offer Price on the Effective Date exceeds $40.00 per Common Share, subject to adjustment as described below, the Make Whole Premium and the number of Make Whole Premium Shares to be issued will be zero; and

(C)

if the Cash Offer Price on the Effective Date is less than $1.20 per Common Share, subject to adjustment as described below, the Make Whole Premium and the number of Make Whole Premium Shares to be issued will be zero.

(v)

The Cash Offer Prices set forth in the table above will be adjusted as of any date on which the Conversion Price of the Initial Debentures is adjusted. The adjusted Cash Offer Prices will equal the Cash Offer Prices applicable immediately prior to such adjustment multiplied by a fraction, the numerator of which is the Conversion Price as so adjusted and the denominator of which is the Conversion Price immediately prior to the adjustment giving rise to the Cash Offer Price adjustment. The number of Make Whole Premium Shares set forth in the table above will be adjusted in the manner that is inversely proportional to the adjustment of the Conversion Price as set forth under Section 6.5, other than as a result of an adjustment to the Conversion Price by adding the Make Whole Premium as described above. The provisions of Section 6.11 shall be applicable in connection with determinations under this Section 2.4(k).

(vi)

Notwithstanding the foregoing, if the Date of Conversion of any Initial Debentures occurs during the period beginning on the tenth trading day prior to the Effective Date and ending at the close of business on the Effective Date, the holders of such Initial Debentures shall, on conversion of their Initial Debentures, only be entitled to receive that number of Make Whole Premium Shares as may be adjusted pursuant to Section 6.5 on the Business Day immediately following the Effective Date and, for greater certainty, only if the Change of Control occurs. The Base Shares shall be issued in accordance with the terms of this Indenture applicable to a conversion of Initial Debentures otherwise than during the Cash Change of Control Conversion Period, including at the then applicable Conversion Price.

(vii)

The Make Whole Premium Shares shall be deemed to have been issued upon conversion of Initial Debentures on the Business Day immediately following the Effective Date. Section 6.5 shall apply to such conversion and, for greater certainty, the former holders of Initial Debentures in respect of which the Make Whole Premium Shares are issuable shall be entitled to receive and shall accept, in lieu of the Make Whole Premium Shares, the number of shares or other securities or property of the Corporation or of the Person or other entity resulting from the transaction that constitutes the Cash Change of Control that such holders would have been entitled to receive if such holders had been the registered holders of the applicable number of Make Whole Premium Shares on the Effective Date.

(viii)

Except as otherwise provided in this Section 2.4(k), all other provisions of this Indenture applicable to a conversion of Initial Debentures shall apply to a conversion of Initial Debentures during the Cash Change of Control Conversion Period.

(l)

The Trustee hereby acknowledges receipt from NBF of a wire transfer of funds in the aggregate amount of $50,000,000 and confirms that such funds have been deposited in a segregated account in the name of the Corporation designated as the "Bellatrix Exploration Ltd. – Initial Debentures", or as otherwise directed by the Corporation and the Lead Underwriter. The Corporation hereby acknowledges that the amount received by the Trustee pursuant to this Subsection 2.4(l) represents payment in full by the Underwriters of the Proceeds for $50,000,000 principal amount of Initial Debentures. The Corporation hereby irrevocably directs the Trustee to, and the Trustee will, retain and pay and release the amounts received by the Trustee pursuant to this Subsection 2.4(l) (and any funds received in respect of any Over-Allotment Debentures issued on any exercise of the Over-Allotment Option) in accordance with the following provisions:

(i)

if the Escrow Release Condition is satisfied prior to the Termination Time the Corporation shall (A) deliver to NBF, on behalf of the Underwriters, an officer's certificate signed on behalf of the Corporation by the President and Chief Executive Officer and the Executive Vice-President, Finance and Chief Financial Officer of the Corporation or such other officers of the Corporation satisfactory to NBF, on behalf of the Underwriters, acting reasonably, certifying, on behalf of the Corporation and without personal liability, that the Disposition Time has occurred and that the Disposition Agreement has not been amended nor have any terms and conditions thereof been waived, other than as disclosed in writing to NBF, on behalf of the Underwriters; (B) shall cause a Closing Notice executed by the Corporation to be delivered to the Trustee and NBF, on behalf of the Underwriters; (C) shall concurrently deliver the Irrevocable Direction to the Trustee executed by the Corporation, to make the payments as provided for herein; and (D) after the Disposition Time, issue a press release setting out the Disposition Date and indicating that the Maturity Date of the Initial Debentures has been extended from the Initial Maturity Date to the Final Maturity Date.

(ii)

Upon receipt of the Closing Notice executed by the Corporation and NBF, on behalf of the Underwriters, and the Irrevocable Direction executed by the Corporation, the Corporation shall be entitled to receive from the Trustee the Escrowed Funds, less the amount payable to NBF on behalf of the Underwriters pursuant to Section 2.4(l)(iii) (the "Released Amount"). The Trustee shall deliver the Released Amount to the Corporation, or to such other party as the Corporation directs in writing, as soon as reasonably practicable after the delivery of the Closing Notice executed by the Corporation and NBF, on behalf of the Underwriters, and the Irrevocable Direction executed by the Corporation.

(iii)

The Trustee shall pay or cause to be paid out of the Escrowed Funds to NBF on behalf of the Underwriters, in accordance with the Underwriting Agreement, an amount equal to fifty percent (50%) of the Underwriters' Fee payable in respect of the Offered Debentures and in respect of any Over-Allotment Debentures issued prior to the delivery of the Closing Notice and the Irrevocable Direction, being an aggregate of $1,000,000 (plus an amount of $20.00 per Over-Allotment Debenture for any Over-Allotment Debenture issued) plus any Earned Interest thereon, forthwith upon receipt of the Closing Notice executed by the Corporation and NBF, on behalf of the Underwriters, and the Irrevocable Direction executed by the Corporation.

(iv)

If the Termination Time occurs, the Corporation shall forthwith notify the Trustee thereof in writing and shall issue a press release setting forth the Initial Maturity Date.

(v)

If the Termination Time occurs, at the Initial Maturity Date the holders of the Initial Debentures shall be entitled to receive the principal amount of the Debentures at par together with all accrued and unpaid interest thereon up to, but excluding, the Initial Maturity Date, which will be satisfied by:

(A)

the payment by the Trustee out of the Escrowed Funds of the aggregate amount of the Initial Debenture Subscription Price in respect of each such holder's Initial Debentures (to be satisfied by the Proceeds) plus such holder's pro rata share of the Earned Interest (without regard to the date of issue of such Initial Debentures) (to be satisfied by the Earned Interest); and

(B)

the payment by the Corporation, of any additional amounts owing in excess of the payment to be made by the Trustee pursuant to Subsection 2.4(l)(v)(A) to account for interest accrued and unpaid on the Debentures up to, but excluding the Initial Maturity Date.

(vi)

The obligation to make the payment of the amounts specified in Subsection 2.4(l)(v) shall be satisfied in accordance with Section 2.13 provided that the Corporation shall only be obligated to deliver to the Trustee a certified cheque or wire transfer for deposit in the applicable Maturity Account in an amount sufficient to the amount as set out in Section 2.4(l)(v)(B). The amount set out in Section 2.4(l)(v)(A) and held by the Trustee and the amount transferred to the Trustee in accordance with this Subsection 2.4(l)(v)(B) shall be deposited to the Maturity Account of the Initial Debentures. Immediately upon the occurrence of the Termination Time the Corporation will hold the amount as set out in Subsection 2.4(l)(v)(B) in trust for the holders of the Initial Debentures until such amount is paid to the Trustee in accordance with this Section 2.4(l)(vi) and Section 2.13. Upon the occurrence of the Termination Time, the Trustee will hold the amount set out in Subsection 2.4(l)(v)(A) and any amount received from the Corporation in respect of Subsection 2.4(l)(v)(B) in trust for the holders of the Initial Debentures.

(vii)

Pending disbursement of the Escrowed Funds, the Trustee shall hold, invest and reinvest such amount in Permitted Investments as directed in writing by the Corporation and the Lead Underwriter. "Permitted Investments" for the Escrowed Funds shall be: (A) Government Obligations having a maturity date of not later than the Deadline, (B) term deposits or bankers' acceptances of a Canadian chartered bank having a maturity date of not later than the Deadline; and (C) such other investments approved by the Corporation and the Lead Underwriter in writing. Such written direction to the Trustee shall be provided no later than 9:00 a.m. (Calgary time) on the day on which the investment is to be made. Any written direction received by the Trustee after 9:00 a.m. (Calgary time) or on a day which is not a Business Day, shall be deemed to have been given prior to 9:00 a.m. (Calgary time) on the next succeeding Business Day.

(viii)

If at any time the Escrowed Funds includes an amount that is not invested in Permitted Investments and the Corporation and the Lead Underwriter have not provided written directions to the Trustee to invest such amount, such uninvested amount will be held in an interest bearing account at a Canadian chartered bank until the Trustee has been directed in writing to so invest and the Trustee shall pay interest on such Escrowed Funds at an annual rate which is equal to 2.50 percent less than the prime rate of interest announced from time to time by The Bank of Nova Scotia on Canadian dollar loans made to its most credit worthy customers in Canada. Such payment obligation shall be calculated daily and paid to the account(s) within three (3) Business Days of each month-end. The Trustee may receive investment earnings in excess of, or less than, the interest payable pursuant to this Section 2.4(l)(viii), such earnings being for the Trustee's benefit or at its risk, as applicable.

(ix)

All earnings received from the investment of the Escrowed Funds shall be credited to, and shall become a part of, the Escrowed Funds. Any bank charges and similar fees as well as losses, if any, on such investments shall be deducted from the Earned Interest provided that if the aggregate amount of such bank charges and similar fees as well as losses are in excess of Earned Interest such excess amount shall be paid by the Corporation and deposited with the Trustee.

(x)

Up and until such time as the Corporation and NBF, as applicable, deliver the Closing Notice and Irrevocable Direction to the Trustee, all amounts held by the Trustee pursuant to Sections 2.4(l)(vii), 2.4(l)(viii), 2.4(l)(ix), 2.4(l)(x) and 2.4(l)(xi) shall be held in escrow by the Trustee for the holders of the Initial Debentures and the delivery of the Escrowed Funds to the Trustee shall not give rise to a debtor creditor or other similar relationship between the Trustee and the Receiptholders. Following delivery of the Closing Notice and Irrevocable Direction to the Trustee by the Corporation and NBF, on behalf of the Underwriters, as applicable, all amounts held by the Trustee pursuant to Sections 2.4(l)(vii), 2.4(l)(viii), 2.4(l)(ix), 2.4(l)(x) and 2.4(l)(xi) shall be held in escrow by the Trustee for the benefit of the Corporation and the Underwriters, as applicable, in accordance with their entitlements hereunder as set out in Subsections 2.4(l)(ii) and 2.4(l)(iii). Except in respect of the interest earned as contemplated in Section 2.4(l)(viii), the amounts held by the Trustee pursuant to Sections 2.4(l)(vii), 2.4(l)(viii), 2.4(l)(ix), 2.4(l)(x) and 2.4(l)(xi) are the sole risk of the Corporation and holders of the Initial Debentures. Except in respect of interest earned as contemplated in Section 2.4(l)(viii), the Trustee shall have no responsibility or liability for any diminution of the Escrowed Funds which may result from any Permitted Investments made pursuant to Section 2.4(l)(vii), including any losses on any investment required to be liquidated prior to maturity in order to make a payment required hereunder.

(xi)

The Escrowed Funds received by the Trustee and any securities or other instruments received by the Trustee upon the investment or reinvestment of such Escrowed Funds, shall be received as agent and in trust for, and shall be segregated and kept apart by the Trustee as agent for (A) up and until such time as the Corporation and NBF, on behalf of the Underwriters, as applicable, deliver the Closing Notice and Irrevocable Direction, the holders of the Initial Debentures, (B) following delivery of the Closing Notice and Irrevocable Direction to the Trustee by the Corporation and NBF, on behalf of the Underwriters, as applicable, the Underwriters and the Corporation, as applicable, in accordance with their entitlements hereunder as set out in Subsections 2.4(l)(ii) and 2.4(l)(iii).

(m)

The Trustee shall be provided with the documents and instruments referred to in Sections 2.5(b), 2.5(c) and 2.5(d) with respect to the Initial Debentures prior to the issuance of the Initial Debentures.

2.5

(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 Additional 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 Authentication and delivery.

2.6

Non-Certificated Deposit

(a)

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

(i)

the deposit of which may be confirmed electronically by the Trustee to a particular Participant through CDS; and

(ii)

shall be identified by a specific CUSIP/ISIN as requested by the Corporation from CDS to identify each specific series of Debentures and the Initial Debentures shall be identified by CUSIP - 00000XX0/ISIN - CA078314AE11.

(b)

If the Corporation issues Debentures in a non-certificated format, Beneficial Owners of such Debentures registered and deposited with CDS shall not receive Debenture Certificates in definitive form and shall not be considered owners or holders thereof under this Indenture or any supplemental indenture. Beneficial interests in Debentures registered and deposited with CDS will be represented only through the non-certificated inventory system administered by CDS. Transfers of Debentures registered and deposited with CDS between Participants shall occur in accordance with the rules and procedures of CDS. Neither the Corporation nor the Trustee shall have any responsibility or liability for any aspects of the records relating to or payments made by CDS or its nominee, on account of the beneficial interests in Debentures registered and deposited with CDS. Nothing herein shall prevent the Beneficial Owners of Debentures registered and deposited with CDS from voting such Debentures using duly executed proxies or voting instruction forms.

(c)

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

(d)

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

(e)

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

(f)

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

(g)

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

(i)

the electronic records maintained by the Depository relating to any ownership interests or any other interests in the Debentures or the depository system maintained by the Depository, or payments made on account of any ownership interest or any other interest of any Person in any Debenture represented by an electronic position in the non-certificated inventory system administered by CDS (other than the Depository or its nominee);

(ii)

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

(iii)

any advice or representation made or given by the Depository or those contained herein that relate to the rules and regulations of the Depository or any action to be taken by the Depository on its own direction or at the direction of any Participant.

(h)

The Corporation may terminate the application of this Section 2.6 in its sole discretion in which case all Debentures shall be evidenced by Debenture Certificates registered in the name of a Person other than the Depository.

2.7

Execution of Debenture Certificates

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

2.8

Authentication

(a)

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

(b)

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

(c)

The Trustee shall Authenticate Uncertificated Debentures (whether upon original issuance, exchange, registration of transfer or otherwise) by completing its Internal Procedures and the Corporation shall, and hereby acknowledges that it shall, thereupon be deemed to have duly and validly issued such Uncertificated Debentures under this Indenture. Such Authentication shall be conclusive evidence that such Uncertificated Debentures have been duly issued hereunder and that the holder or holders are entitled to the benefits of this Indenture. The register shall be final and conclusive evidence as to all matters relating to Uncertificated Debentures with respect to which this Indenture requires the Trustee to maintain records or accounts. In case of differences between the register at any time and any other time the register at the later time shall be controlling, absent manifest error and such Uncertificated Debentures are binding on the Corporation.

2.9

Interim Debentures or Certificates

Pending the delivery of definitive Debentures of any series to the Trustee, the Corporation may issue and the Trustee may Authenticate in lieu thereof interim Debentures in such forms and in such denominations and signed in such manner as provided herein, entitling the holders thereof to definitive Debentures of the series when the same are ready for delivery; or the Corporation may execute and the Trustee may Authenticate a temporary Debenture for the whole principal amount of Debentures of the series then authorized to be issued hereunder and deliver the same to the Trustee and thereupon the Trustee may issue its own interim certificates in such form and in such amounts, not exceeding in the aggregate the principal amount of the temporary Debenture so delivered to it, as the Corporation and the Trustee may approve entitling the holders thereof to definitive

Debentures of the series when the same are ready for delivery; and, when so issued and Authenticated, such interim or temporary Debentures or interim certificates shall, for all purposes but without duplication, rank in respect of this Indenture equally with Debentures duly issued hereunder and, pending the exchange thereof for definitive Debentures, the holders of the interim or temporary Debentures or interim certificates shall be deemed without duplication to be Debentureholders and entitled to the benefit of this Indenture to the same extent and in the same manner as though the said exchange had actually been made. Forthwith after the Corporation shall have delivered the definitive Debentures to the Trustee, the Trustee shall cancel such temporary Debentures, if any, and shall call in for exchange all interim Debentures or certificates that shall have been issued and forthwith after such exchange shall cancel the same. No charge shall be made by the Corporation or the Trustee to the holders of such interim or temporary Debentures or interim certificates for the exchange thereof. All interest paid upon interim or temporary Debentures or interim certificates shall be noted thereon as a condition precedent to such payment unless paid by cheque to the registered holders thereof.

2.10

Mutilation, Loss, Theft or Destruction

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

2.11

Concerning Interest

(a)

Except as may otherwise be provided in this Indenture or in any supplemental indenture or in a Written Direction of the Corporation in respect of a series of Debentures and subject to Section 2.4(c) with respect to the calculation of interest in respect of the initial interest payment to be paid on the Initial Debentures, 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 shall be computed on the basis of a year of 365 days and shall be based on the actual number of days in the applicable period. With respect to any series of Debentures, whenever interest is computed on the basis of a year (the "deemed year") which contains fewer days than the actual number of days in the calendar year of calculation, such rate of interest shall be expressed as a yearly rate for purposes of the Interest Act (Canada) by multiplying such rate of interest by the actual number of days in the calendar year of calculation and dividing it by the number of days in the deemed year.

2.12

Debentures to Rank Pari Passu

The Debentures will be direct unsecured subordinated 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, for certainty, Senior Indebtedness, to the extent that such other existing and future subordinated unsecured indebtedness of the Corporation is subordinated on the same terms.

2.13

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 Trustee a Maturity Account for each series of Debentures. Each such Maturity Account shall be maintained by and be subject to the control of the Trustee for the purposes of this Indenture. On or before 11:00 a.m. (Calgary time) on the Business Day immediately prior to each Maturity Date for Debentures outstanding from time to time under this Indenture, the Corporation will deliver to the Trustee a certified cheque or wire transfer for deposit in the applicable Maturity Account in an amount sufficient to pay the cash amount payable in respect of such Debentures (including the principal amount together with any accrued and unpaid interest thereon less any tax required by law to be deducted), provided the Corporation may elect to satisfy this requirement by providing the Trustee with a cheque or with funds by electronic transfer for such amounts required under this Section 2.13 post-dated to the applicable Maturity Date. The Trustee, on behalf of the Corporation, will pay to each holder entitled to receive payment the principal amount of and premium (if any) and accrued and unpaid interest on the Debenture, upon surrender of the Debenture at any branch of the Trustee designated for such purpose from time to time by the Corporation and the Trustee. The delivery of such funds to the Trustee for deposit to the applicable Maturity Account will satisfy and discharge the liability of the Corporation for the Debentures to which the delivery of funds relates to the extent of the amount delivered (plus the amount of any tax deducted as aforesaid and remitted to the appropriate governmental authority) 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.

2.14

Payment of Interest

The following provisions shall apply to Debentures, except as otherwise provided in Section 2.4(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 2.4(c), on conversion or on redemption, when interest may at the option of the Corporation be paid upon surrender of such Debenture), the Corporation, either directly or through the Trustee or any agent of the Trustee, shall send or forward by prepaid ordinary mail, electronic transfer of funds or such other means as may be agreed to by the Trustee, payment of such interest (less any tax required to be withheld therefrom) to the order of the registered holder of such Debenture appearing on the registers maintained by the Trustee at the close of business on the 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 Trustee must receive confirmation of receipt of funds one Business Day prior to being able to wire funds to holders), such payment shall be made in a manner whereby the holder receives credit for such payment on the date such interest on such Debenture becomes due. The mailing of such cheque or the making of such payment by other means shall, to the extent of the sum represented thereby, plus the amount of any tax withheld and remitted to the appropriate governmental authority as aforesaid, satisfy and discharge all liability for interest on such Debenture, unless in the case of payment by cheque, such cheque is not paid at par on presentation. In the event of non-receipt of any cheque for or other payment of interest by the person to whom it is so sent as aforesaid, the Corporation will issue to such person a replacement cheque or other payment for a like amount upon being furnished with such evidence of non-receipt as it shall reasonably require and upon being indemnified to its satisfaction. Notwithstanding the foregoing, if the Corporation is prevented by circumstances beyond its control (including, without limitation, any interruption in mail service) from making payment of any interest due on each Debenture in the manner provided above, the Corporation may make payment of such interest or make such interest available for payment in any other manner acceptable to the Trustee with the same effect as though payment had been made in the manner provided above.

(b)

All payments of interest on the Uncertificated 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 Owners of the applicable Uncertificated Debenture, unless the Corporation and the Depository otherwise agree. On or before 11:00 a.m. (Calgary time) on the Business Day immediately prior to each Interest Payment Date for Uncertificated Debentures outstanding from time to time under this Indenture, the Corporation will deliver to the Trustee a certified cheque or wire transfer in an amount sufficient to pay the cash amount payable in respect of interest on such Uncertificated Debentures on such Interest Payment Date, provided the Corporation may elect to satisfy this requirement by providing the Trustee with a cheque for such amounts required under this Section 2.14(b) post-dated to the applicable Interest Payment Date. None of the Corporation, the Trustee or any agent of the Trustee for any Debenture issued as an Uncertificated Debenture will be liable or responsible to any person for any aspect of the records related to or payments made on account of beneficial interests in any Uncertificated Debenture or for maintaining, reviewing, or supervising any records relating to such beneficial interests.

2.15

Withholding Tax

The Corporation will be entitled to deduct and withhold any applicable taxes or similar charges (including interest, penalties or similar amounts in respect thereof) imposed or levied by or on behalf of the Canadian government or of any Province or territory thereof or any authority or agency therein or thereof having power to tax, including pursuant to the Tax Act, from any payment to be made on or in connection with the Debentures and, provided that the Corporation forthwith remits such withheld amount to such government, authority or agency and files all required forms in respect thereof and, at the same time, provides copies of such remittance and filing to the Trustee and the relevant Debentureholder, the amount of any such deduction or withholding will be considered an amount paid in satisfaction of the Corporation's obligations under the Debentures and there is no obligation on the Corporation to gross-up amounts paid to a holder in respect of such deductions or withholdings. The Corporation shall provide the Trustee and the relevant Debentureholder with copies of receipts or other communications relating to the remittance of such withheld amount or the filing of such forms received from such government, authority or agency promptly after receipt thereof.

The Trustee shall have no obligation to verify any payments under the Tax Act or any provision of provincial, state, local or foreign tax law. The Trustee shall at all times be indemnified and held harmless by the Corporation from and against any personal liabilities of the Trustee incurred in connection with the failure of the Corporation or its agents, to report, remit or withhold taxes as required by the Tax Act or otherwise failing to comply with the Tax Act. This indemnification shall survive the resignation or removal of the Trustee and the termination of this Indenture solely to the extent that such liabilities have been incurred in connection with taxation years occurring during the term of this Indenture.

2.16

Right of Rescission

(a)

Upon the conversion of the principal amount of an Initial Debenture into Common Shares pursuant to Article 6 hereof, original purchasers of Initial Debentures under the Initial Debenture Offering (the "Original Purchasers") shall have a right of action against the Corporation for rescission to receive the purchase price of the Initial Debentures, exercisable on notice given to the Corporation not more than 180 days subsequent to the date hereof, if the Prospectus, together with any amendment thereto, contains a misrepresentation (as such term is defined in the Securities Act (Alberta)). The foregoing right of action for rescission is only available to an Original Purchaser while he or she is a holder of the Common Shares issued upon the conversion of Initial Debentures pursuant to Article 6 hereof.

(b)

In no event shall the Corporation be liable under this Section 2.16 if the Original Purchaser purchased the Initial Debentures with knowledge of the misrepresentation.

Article 3
REGISTRATION, TRANSFER, EXCHANGE AND OWNERSHIP

3.1

Fully Registered Debentures

(a)

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

(b)

No transfer of a Fully Registered Debenture shall be valid unless made on such register referred to in Section 3.1(a) by the registered holder or such holder's executors, administrators or other legal representatives or an attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Trustee or other registrar upon surrender of the Debentures together with a duly executed form of transfer acceptable to the Trustee and upon compliance with such other reasonable requirements as the Trustee or other registrar may prescribe, or unless the name of the transferee shall have been noted on the Debenture by the Trustee or other registrar.

(c)

Fully Registered Debentures and the Common Shares issuable upon conversion thereof have not been and will not be registered under the 1933 Act and may only be transferred pursuant to an exemption or exclusion from the registration requirements of the 1933 Act and applicable state securities laws.

3.2

Transferee Entitled to Registration

The transferee of a Debenture shall be entitled, after the appropriate form of transfer is lodged with the Trustee or other registrar and upon compliance with all other conditions in that behalf required by this Indenture or by law, to be entered on the register as the owner of such Debenture free from all equities or rights of set-off or counterclaim between the Corporation and the transferor or any previous holder of such Debenture, save in respect of equities of which the Corporation is required to take notice by statute or by order of a court of competent jurisdiction. Upon surrender for registration of transfer of Debentures, the Corporation shall issue and thereupon the Trustee shall Authenticate and deliver a new Debenture Certificate or confirm the electronic deposit of Uncertificated Debentures of like tenor in the name of the designated transferee and register such transfer in accordance with Section 3.1. If less than all the Debentures evidenced by the Debenture Certificate(s) or Uncertificated Debentures so surrendered are transferred, the transferor shall be entitled to receive, in the same manner, a new Debenture Certificate or electronically deposited Uncertificated Debentures registered in his name evidencing the Debentures not transferred.

3.3

No Notice of Trusts

Neither the Corporation nor the Trustee nor any registrar shall be bound to take notice of or see to the execution of any trust (other than that created by this Indenture) whether express, implied or constructive, in respect of any Debenture, and may transfer the same on the direction of the person registered as the holder thereof, whether named as trustee or otherwise, as though that person were the beneficial owner thereof.

3.4

Registers Open for Inspection

The registers referred to in Section 3.1 shall at all reasonable times be open for inspection by the Corporation, the Trustee or any Debentureholder. Every registrar, including the Trustee, shall from time to time when requested so to do by the Corporation or by the Trustee, in writing, furnish the Corporation or the Trustee, as the case may be, with a list of names and addresses of holders of registered Debentures entered on the register kept by them and showing the principal amount and serial numbers of the Debentures held by each such holder, provided the Trustee shall be entitled to charge a reasonable fee to provide such a list.

3.5

Exchanges of Debenture Certificates

(a)

Subject to Section 3.6, Debentures in any authorized form or denomination, other than Uncertificated 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.

(b)

In respect of exchanges of Debentures permitted by Section 3.5(a), Debentures of any series may be exchanged only at the principal offices of the Trustee in the cities of Calgary, Alberta and Toronto, Ontario or at such other place or places, if any, as may be specified in the Debentures of such series and at such other place or places as may from time to time be designated by the Corporation with the approval of the Trustee. Any Debentures tendered for exchange shall be surrendered to the Trustee. The Corporation shall execute and the Trustee shall Authenticate all Debentures necessary to carry out exchanges as aforesaid. All Debentures surrendered for exchange shall be cancelled.

(c)

Debentures issued in exchange for Debentures which at the time of such issue have been selected or called for redemption at a later date shall be deemed to have been selected or called for redemption in the same manner and shall have noted thereon a statement to that effect.

3.6

(i)

make transfers or exchanges or convert any of Fully Registered Debentures on any Interest Payment Date for such Debentures or during the five preceding Business Days;

(ii)

make transfers or exchanges of, or convert any Debentures on the day of any selection by the Trustee of Debentures to be redeemed or during the five preceding Business Days; or

(iii)

make exchanges of any Debentures which will have been selected or called for redemption unless upon due presentation thereof for redemption such Debentures shall not be redeemed.

(b)

Subject to any restriction herein provided, the Corporation with the approval of the Trustee may at any time close any register for any series of Debentures, other than those kept at the principal offices of the Trustee in Xxxxxxx, Xxxxxxx xxx Xxxxxxx, Xxxxxxx, and transfer the registration of any Debentures registered thereon to another register (which may be an existing register) and thereafter such Debentures shall be deemed to be registered on such other register. Notice of such transfer shall be given to the holders of such Debentures.

3.7

Charges for Registration, Transfer and Exchange

For each Debenture exchanged, registered, transferred or discharged from registration, the Trustee or other registrar, except as otherwise herein provided, may make a reasonable charge for its services and in addition may charge a reasonable sum for each new Debenture issued (such amounts to be agreed upon from time to time by the Trustee and the Corporation), and payment of such charges and reimbursement of the Trustee or other registrar for any stamp taxes or governmental or other charges required to be paid shall be made by the party requesting such exchange, registration, transfer or discharge from registration as a condition precedent thereto. Notwithstanding the foregoing provisions, no charge shall be made to a Debentureholder hereunder:

(a)

for any exchange, registration, transfer or discharge from registration of any Debenture applied for within a period of two months from the date of the first delivery of Debentures of that series or, with respect to Debentures subject to a Periodic Offering, within a period of two months from the date of delivery of any such Debenture;

Unless otherwise required by law, the person in whose name any registered Debenture is registered shall for all purposes of this Indenture be and be deemed to be the owner thereof and payment of or on account of the principal of and premium, if any, on such Debenture and interest thereon shall be made to such registered holder.

(b)

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

(c)

Where Debentures are registered in more than one name, the principal, premium, if any, and interest from time to time payable in respect thereof may be paid to the order of all such holders, failing written instructions from them to the contrary, and the receipt of any one of such holders therefor shall be a valid discharge, to the Trustee, any registrar and to the Corporation.

(d)

In the case of the death of one or more joint holders of any Debenture the principal, premium, if any, and interest from time to time payable thereon may be paid to the order of the survivor or survivors of such registered holders and the receipt of any such survivor or survivors therefor shall be a valid discharge to the Trustee and any registrar and to the Corporation.

Article 4
REDEMPTION AND PURCHASE OF DEBENTURES
AND CERTAIN PAYMENTS ON MATURITY

4.1

Applicability of Article

Subject to regulatory approval, Sections 2.4(d), 7.11, Article 5, and the provisions relating to any particular series of Debentures, 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 Authentication and delivery thereof.

Subject to regulatory approval and Article 5, the Corporation shall also have the right at its option to repay, either in whole or in part, on redemption or at maturity, either by payment of money in accordance with Section 2.13, by issuance of Freely Tradeable Common Shares as provided in Sections 4.6 and 4.10 or any combination thereof, the principal amount of 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 Authentication 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 Trustee 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 Trustee deems equitable, subject to the approval of the TSX (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 Trustee 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 Trustee shall Authenticate 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 an Uncertificated Debenture, registration and surrender of interests in the Debentures will be made only through the Depository's non-certificated system. 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, if applicable, the portion to be redeemed for cash and the portion to be redeemed by issuing Freely Tradeable Common Shares 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 pro rata or other similar system, such particulars as may be sufficient to identify the Debentures so selected;

(c)

in the case of an Uncertificated Debenture, that the redemption will take place in such manner as may be agreed upon by the Depository, the Trustee 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.

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 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 Trustee as to the publication and/or mailing of such notices shall have been lodged with it, 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 Trustee 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 Trustee or any paying agent to the order of the Trustee, on or before 11:00 a.m. (Calgary time) on the Business Day immediately prior to the Redemption Date specified in such notice, such sums of money, or 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, provided the Corporation may elect to satisfy this requirement by providing the Trustee with a certified cheque or wire transfer for such amounts required under this Section 4.5 post-dated to the Redemption Date or by providing the Trustee with such funds through electronic transfer of funds on the Business Day immediately prior to the Redemption Date. The Corporation shall also deposit with the Trustee a sum of money sufficient to pay any charges or expenses which may be incurred by the Trustee in connection with such redemption. Every such deposit shall be irrevocable. From the sums so deposited, or Common Shares so deposited, or both, the Trustee 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 Principal Portion of Redemption Price in Common Shares

(a)

Subject to the receipt of any required regulatory approvals, the provisions governing any series of Debentures and the other provisions of this Section 4.6, the Corporation may, at its option, in exchange for or in lieu of paying the principal portion of the Redemption Price in money, elect to satisfy its obligation to pay all or any portion of the principal 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 principal portion of Redemption Price (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 (which will be calculated based on the 20 consecutive trading days ending five days before the Redemption Date) (the "Common Share Redemption Right").

(b)

The Corporation shall exercise the Common Share Redemption Right by so specifying in the Redemption Notice 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; provided that if the Corporation elects to exercise the Common Share Redemption Right, the Redemption Notice shall be given to holders of the Debentures so to be redeemed not more than 60 days nor less than 40 days prior to the Redemption Date.

(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 Applicable Securities Legislation and such Common Shares shall be issued as Freely Tradeable Common Shares;

(ii)

the Common Shares shall be listed on the TSX or such other recognized stock exchange and such additional Freely Tradeable Common Shares shall be listed on each stock exchange on which the Common Shares are then listed;

(iii)

the Corporation shall be a reporting issuer in good standing under Applicable Securities Legislation where the distribution of such Freely Tradeable Common Shares occurs;

(iv)

the Corporation shall be in compliance with Section 7.11;

(v)

no Event of Default shall have occurred and be continuing;

(vi)

the Trustee shall have received an Officers' Certificate stating that conditions (i), (ii), (iii), (iv) and (v) 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

(vii)

the Trustee shall have received an opinion of Counsel to the effect that such Common Shares have been duly authorized and, when issued and delivered pursuant to the terms of this Indenture in payment of the Redemption Price, will be validly issued as fully paid and non-assessable, that conditions (i) and (ii) above have been satisfied and that, relying exclusively on lists of issuers in default maintained by the relevant securities authorities, condition (iii) above is satisfied, except that the opinion in respect of condition (iii) need not be expressed with respect to those provinces where such lists are not maintained.

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. The Corporation may not change the form of components or percentage of consideration to be paid for the Debentures except as described in the preceding sentence. When the Corporation determines the actual number of the Common Shares to be issued pursuant to the Corporation's exercise of its Common Share Redemption 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 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 place specified in the Redemption Notice, the Corporation shall on or before 11:00 a.m. (Calgary time) on the Business Day immediately prior to the Redemption Date make the delivery to the Trustee for delivery to and on account of the holders, of certificates representing the Freely Tradeable Common Shares to which such holders are entitled.

(e)

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 Trustee for the account of the holders, at the time contemplated in Section 4.6(d), the cash equivalent thereof determined on the basis of the Current Market Price of the Common Shares on the Redemption Date (less any tax required to be deducted, if any).

(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 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 Trustee receives the same, it shall hold the same in trust for the benefit of such holder.

(g)

If the Corporation exercises its Common Share Redemption Right, 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.

(h)

The Corporation shall comply with all Applicable Securities Legislation regulating the issue and delivery of Freely Tradeable Common Shares upon exercise of the Common Share Redemption Right and shall cause to be listed and posted for trading such Common Shares on each stock exchange on which the Common Shares are then listed.

(i)

The Corporation shall from time to time promptly pay, or make provision satisfactory to the Trustee for the payment of, all taxes and charges which may be imposed by the laws of Canada or any province thereof (except income tax, withholding tax or security transfer tax, if any) which shall be payable with respect to the issuance or delivery of 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.

(j)

If the Corporation elects to satisfy its obligation to pay all or any portion of the Redemption Price by issuing Freely Tradeable Common Shares in accordance with this Section 4.6 and if the Redemption Price (or any portion thereof) to which a holder is entitled is subject to withholding taxes and the amount of the cash payment of the Redemption Price, if any, is insufficient to satisfy such withholding taxes, the Trustee, on the Written Direction of the Corporation but for the account of the holder, shall sell, through the investment banks, brokers or dealers selected by the Corporation, out of the Freely Tradeable Common Shares issued by the Corporation for this purpose, such number of Freely Tradeable Common Shares that together with the cash payment of the Redemption Price, if any, is sufficient to yield net proceeds (after payment of all costs) to cover the amount of taxes required to be withheld, and shall remit same on behalf of the Corporation to the proper tax authorities within the period of time prescribed for this purpose under applicable laws. Any amount of net proceeds (after payment of all costs) in excess of the amount required to cover applicable tax required by applicable law to be withheld will be remitted to the Debentureholder.

(k)

Interest accrued and unpaid on the Debentures on the Redemption Date will be paid, less applicable withholding taxes, if any, to holders of Debentures, in cash, in the manner contemplated in Section 2.14 subject to the ability of the Corporation to issue Common Shares as provided for in Article 10.

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 Common Shares issuable in respect thereof, or give such receipt therefor, if any, as the Trustee may require, such redemption monies may be set aside in trust, or such Common Shares may be held in trust without interest, either in the deposit department of the Trustee or in a chartered bank, and such setting aside shall for all purposes be deemed a payment to the Debentureholder of the sum or 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 Common Shares 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. In the event that any money, or Common Shares, required to be deposited hereunder with the Trustee or any depository or paying agent on account of principal, premium, if any, or interest, if any, on Debentures issued hereunder shall remain so deposited for a period of three years less one day from the Redemption Date, then such monies or Common Shares, together with any accumulated interest thereon or any distribution paid thereon, shall at the end of such period be paid over or delivered over by the Trustee or such depository or paying agent to the Corporation on its demand, and thereupon the Trustee shall not be responsible to Debentureholders for any amounts owing to them and subject to applicable law, thereafter the holder of a Debenture in respect of which such money was so repaid to the Corporation shall have no rights in respect thereof except to obtain payment of the money or Common Shares due from the Corporation, subject to any limitation period provided by the laws of Alberta. Notwithstanding the foregoing, the Trustee will pay any remaining funds prior to the expiry of three years less one day after the Redemption 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 three years less one day after the Redemption Date, the Corporation shall reimburse the Trustee for any amounts required to be paid by the Trustee to a holder of a Debenture pursuant to the redemption after the date of such payment of the remaining funds to the Corporation but prior to three 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 Trustee and cancelled and no Debentures shall be issued in substitution therefore.

4.9

Purchase of Debentures by the Corporation

Subject to Applicable Securities Legislation and 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 private contract, at any price. All Debentures so purchased will be delivered to the Trustee and shall be cancelled and no Debentures shall be issued in substitution therefor.

If, upon an invitation for tenders, more Debentures are tendered at the same lowest price that the Corporation is prepared to accept, the Debentures to be purchased by the Corporation shall be selected by the Trustee on a pro rata basis or in such other manner as consented to by the TSX (or such other exchange on which the Debentures are then listed which the Trustee considers appropriate), from the Debentures tendered by each tendering Debentureholder who tendered at such lowest price. For this purpose the Trustee may make, and from time to time amend, regulations with respect to the manner in which Debentures may be so selected, and regulations so made shall be valid and binding upon all Debentureholders, notwithstanding the fact that as a result thereof one or more of such Debentures become subject to purchase in part only. The holder of a Debenture Certificate 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 Debenture Certificates for the unpurchased part so surrendered, and the Trustee shall Authenticate and deliver such new Debenture Certificate(s) upon receipt of the Debenture so surrendered or, with respect to Uncertificated Debentures, the Depository shall electronically deposit the unpurchased part so surrendered.

4.10 Right to Repay Principal Amount in Common Shares

(a)

Subject to the receipt of any required regulatory approvals, the provisions governing any series of Debentures and the other provisions of this Section 4.10, the Corporation may, at its option, in exchange for or in lieu of repaying the principal amount of the Debentures in money, elect to satisfy its obligation to repay 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 (which will be calculated based on the 20 consecutive trading days ending five trading days before the Maturity Date) (the "Common Share Repayment Right").

(b)

The Corporation shall exercise the Common Share Repayment Right by so specifying in the Maturity Notice, which shall be delivered to the Trustee 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.

(c)

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

(i)

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

(ii)

(iii)

the Corporation shall be a reporting issuer in good standing under Applicable Securities Legislation where the distribution of such Freely Tradeable Common Shares occurs;

(iv)

no Event of Default shall have occurred and be continuing;

the Corporation shall be in compliance with Section 7.11;

(vi)

(vii)

the Trustee shall have received an opinion of Counsel to the effect that such Common Shares have been duly authorized and, when issued and delivered pursuant to the terms of this Indenture in payment of the principal amount of the Debentures outstanding will be validly issued as fully paid and non-assessable, that conditions (i) and (ii) above have been satisfied and that, relying exclusively on lists of issuers in default maintained by the relevant securities authorities, condition (iii) above is satisfied, except that the opinion in respect of condition (iii) need not be expressed with respect to those provinces where such lists are not maintained.

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 2.13, 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. (Calgary time) on the Business Day immediately prior to the Maturity Date make the delivery to the Trustee for delivery to and on account of the holders, of the Freely Tradeable Common Shares to which such holders are entitled. The Corporation shall also deposit with the Trustee a sum of money sufficient to pay all accrued and unpaid interest on the Debentures and any charges or expenses which may be incurred by the Trustee in connection with the Common Share Repayment Right. Every such deposit shall be irrevocable. From the Common Shares so deposited in addition to amounts payable by the Trustee pursuant to Section 2.13, the Trustee shall pay or cause to be paid, to the holders of such Debentures, upon surrender of such Debentures, the principal amount of and premium (if any) on the Debentures to which they are respectively entitled on maturity and deliver to such holders the Common Shares to which such holders are entitled. The delivery of such shares to the Trustee will satisfy and discharge the liability of the Corporation for the Debentures to which the delivery of shares relates to the extent of the amount delivered (plus the amount of any shares sold to pay applicable taxes in accordance with this Section 4.10) 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 shares so delivered, the share(s) to which it is entitled.

(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 Trustee 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 (less any tax required to be deducted, if any).

(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 Trustee receives the same, it shall hold the same in trust for the benefit of such holder.

(g)

If the Corporation exercises the Common Share Repayment Right, 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 Repayment 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 Repayment 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.

(h)

The Corporation shall comply with all Applicable Securities Legislation regulating the issue and delivery of Freely Tradeable Common Shares upon exercise of the Common Share Repayment Right and shall cause to be listed and posted for trading such Freely Tradeable Common Shares on each stock exchange on which the Common Shares are then listed.

(i)

The Corporation shall from time to time promptly pay, or make provision satisfactory to the Trustee for the payment of, all taxes and charges which may be imposed by the laws of Canada or any province thereof (except income tax, withholding tax or security transfer tax, if any) which shall be payable with respect to the issuance or delivery of 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.

(j)

If the Corporation elects to satisfy its obligation to pay all or any portion of the principal amount of Debentures due on maturity by issuing Freely Tradeable Common Shares in accordance with this Section 4.10 and if the amount (or any portion thereof) to which a holder is entitled is subject to withholding taxes and the amount of the cash payment of the amount due on maturity, if any, is insufficient to satisfy such withholding taxes, the Trustee, on the Written Direction of the Corporation but for the account of the holder, shall sell, through the investment banks, brokers or dealers selected by the Corporation, out of the Freely Tradeable Common Shares issued by the Corporation for this purpose, such number of Freely Tradeable Common Shares that together with the cash component of the amount due on maturity is sufficient to yield net proceeds (after payment of all costs) to cover the amount of taxes required to be withheld, and shall remit same on behalf of the Corporation to the proper tax authorities within the period of time prescribed for this purpose under applicable laws.

(k)

Interest accrued and unpaid on the Debentures on the applicable Maturity Date will be paid, less applicable withholding taxes, if any, to holders of Debentures, in cash, in the manner contemplated in Section 2.14 subject to the ability of the Corporation to issue Common Shares as provided in Article 10.

5.5

No Payment if Senior Indebtedness in Default

Upon the maturity of any Senior Indebtedness by lapse of time, acceleration or otherwise, or any other enforcement of any Senior Indebtedness, then all such Senior Indebtedness shall first be paid in full, or shall first have been duly provided for, before any payment is made on account of the Debenture Liabilities.

In case of a circumstance constituting a default or event of default with respect to any Senior Indebtedness permitting (whether at that time or upon notice, lapse of time, or satisfaction of any other condition precedent) a Senior Creditor to demand payment or accelerate the maturity thereof where the notice of such default or event of default has been given by or on behalf of the Senior Creditors to the Corporation or the Corporation otherwise has knowledge thereof, unless and until such default or event of default shall have been cured or waived or shall have ceased to exist, no payment (by purchase of Debentures or otherwise) shall be made by the Corporation with respect to the Debenture Liabilities and neither the Trustee nor the holders of Debentures shall be entitled to demand, accelerate, institute proceedings for the collection of (which shall, for certainty include, without limitation, proceedings related to an adjudication or declaration as to the insolvency or bankruptcy of the Corporation and other similar creditor proceedings), or receive any payment or benefit (including without limitation by set-off, combination of accounts or otherwise in any manner whatsoever) on account of the Debentures after the happening of such a default or event of default (except as provided in Section 5.8), and unless and until such default or event of default shall have been cured or waived or shall have ceased to exist, such payments shall be held in trust for the benefit of, and, if and when such Senior Indebtedness shall have become due and payable, shall be paid over to the Senior Creditors until all such Senior Indebtedness shall have been paid in full, after giving effect to any concurrent payment or distribution to the Senior Creditors; provided, however, that, subject to the priorities and rights of the Senior Creditors under this Article 5, the foregoing shall in no way prohibit, restrict or prevent the Trustee from taking such actions as may be necessary to preserve claims of the Trustee and/or the holders of the Debentures under this Indenture in any bankruptcy, reorganization or insolvency proceeding (including, without limitation, the filing of proofs of claim in any such bankruptcy, reorganization or insolvency proceedings by or against the Corporation or its Subsidiaries and exercising its rights to vote as an unsecured creditor under any such bankruptcy, reorganization or insolvency proceedings commenced by or against the Corporation or its Subsidiaries).

The fact that any payment hereunder is prohibited by this Section 5.5 shall not prevent the failure to make such payment from being an Event of Default hereunder.

5.6

Payment on Debentures Permitted

Nothing contained in this Article 5 or elsewhere in this Indenture, or in any of the Debentures, shall affect the obligation of the Corporation to make, or prevent the Corporation from making, at any time except as prohibited by Section 5.2 or 5.5, any payment of principal of or, premium, if any, or interest on the Debentures as the same may become due. The fact that any such payment is prohibited by Section 5.2 or 5.5 shall not prevent the failure to make such payment from being an Event of Default hereunder. Nothing contained in this Article 5 or elsewhere in this Indenture, or in any of the Debentures, shall prevent the conversion of the Debentures or, except as prohibited by Sections 5.2 and 5.5, the application by the Trustee of any monies deposited with the Trustee hereunder for such purpose, to the payment of or on account of the Debenture Liabilities.

5.7

Confirmation of Subordination

Each holder of Debentures by his acceptance thereof authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effect the subordination as provided in this Article 5 and appoints the Trustee his attorney-in-fact for any and all such purposes. Upon request of the Corporation, and upon being furnished an Officers' Certificate stating that one or more named Persons are Senior Creditors and specifying the amount and nature of the Senior Indebtedness of such Senior Creditor, the Trustee shall enter into a written agreement or agreements with the Corporation and the Person or Persons named in such Officers' Certificate providing that such Person or Persons are entitled to all the rights and benefits of this Article 5 as a Senior Creditor and for such other matters, as the Senior Creditor may reasonably request, including, without limitation, those items set out in Section 5.17. Such agreement shall be conclusive evidence that the indebtedness specified therein is Senior Indebtedness, however, nothing herein shall impair the rights of any Senior Creditor who has not entered into such an agreement.

5.8

Knowledge of Trustee

Notwithstanding the provisions of this Article 5 or any provision in this Indenture or in the Debentures contained, the Trustee will not be charged with knowledge of any default in the payment of any Senior Indebtedness, 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 Trustee, or the taking of any other action by the Trustee, unless and until the Trustee has received written notice thereof from the Corporation, any Debentureholder or any Senior Creditor. The Trustee will notify holders of Debentures of such notice as soon as reasonably practicable after receipt thereof.

5.9

Trustee May Hold Senior Indebtedness

The Trustee is entitled to all the rights set forth in this Article 5 with respect to any Senior Indebtedness at the time held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture deprives the Trustee of any of its rights as such holder.

5.10

Rights of Senior Creditors Not Impaired

No right of any present or future Senior Creditor to enforce the subordination herein will at any time or in any way be prejudiced or impaired by any act or failure to act on the part of the Corporation or by any non-compliance by the Corporation with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof which any such Senior Creditor may have or be otherwise charged with.

5.11

Altering the Senior Indebtedness

The Senior Creditors have the right to extend, renew, revise, restate, modify or amend the terms of the Senior Indebtedness (including, without limitation, increasing the principal amount of the Senior Indebtedness) or any Senior Security and to release, sell or exchange such security and otherwise to deal freely with the Corporation and its Subsidiaries, all without notice to or consent of the Debentureholders or the Trustee and without affecting the liabilities and obligations of the parties to this Indenture or the Debentureholders.

5.12

Additional Indebtedness

This Indenture does not restrict the Corporation or any Subsidiary of the Corporation from incurring additional indebtedness for borrowed money or other obligations or liabilities (including, without limitation, Senior Indebtedness) or mortgaging, pledging or charging its properties to secure any indebtedness or obligations or liabilities.

5.13

Right of Debentureholder to Convert Not Impaired

The subordination of the Debenture Liabilities to the Senior Indebtedness and the provisions of this Article 5 do not impair in any way the right of a Debentureholder to convert its Debentures pursuant to Article 6.

5.14

Invalidated Payments

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

5.15

Contesting Security

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

5.16

Obligations Created by Article 5

The Corporation and the Trustee, in its capacity as trustee hereunder and not in its corporate or personal capacity, agree, and each holder by its acceptance of a Debenture, whether directly or on the holder's behalf, likewise agrees, that:

(a)

the provisions of this Article 5 are an inducement and consideration to each Senior Creditor to give or continue credit to the Corporation, the Corporation's Subsidiaries or others or to acquire Senior Indebtedness; and

(b)

each Senior Creditor may accept the benefit of this Article 5 on the terms and conditions set forth in this Article 5 by giving or continuing credit to the Corporation, the Corporation's Subsidiaries or others or by having outstanding or acquiring Senior Indebtedness, in each case without notice to the Trustee and without establishing actual reliance on this Article 5.

5.17

Amendment to Indenture

Each of the Corporation and the Trustee (relying on the opinion of Counsel) agrees, and each holder of a Debenture, by his acceptance thereof, whether directly or on the holder's behalf, likewise agrees, not to make any changes to this Indenture or the Debentures which prejudice the rights of the Senior Creditors under this Article 5, and without limiting the generality of the foregoing, not amend, terminate or otherwise alter: (i) any of the provisions of this Article 5 nor any of the defined terms used therein; (ii) provisions to reduce the maturity date of the Debentures; (iii) provisions to increase the interest rate or change the interest payment dates of the Debentures; or (iv) the provisions that would result in an earlier date for any scheduled or mandatory payment, redemption or repurchase of principal under the Initial Debentures or create any new scheduled or mandatory payment, redemption or repurchase of principal under the Initial Debentures.

5.18

Payment on Initial Maturity Date

Notwithstanding anything to the contrary in this Article 5 or in any other provision of this Debenture including Section 2.4(e), until the Escrow Release Condition has been satisfied, this Article 5 shall not apply to the Escrowed Funds or otherwise restrict payment to the holders of the Initial Debentures on the Initial Maturity Date in accordance with Sections 2.4(l)(v) and 2.4(l)(vi) of the principal amount of the Debentures at par together with all accrued and unpaid interest thereon up to, but excluding, the Initial Maturity Date.

Article 6
CONVERSION OF DEBENTURES

6.1

Applicability of Article

Any Debentures issued hereunder of any series which by their terms are convertible (subject, however, to any applicable restriction of the conversion of Debentures of such series) will be convertible into Common Shares or other securities of the Corporation, at such conversion rate or rates, 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 shall have been expressed in this Indenture (including Sections 2.4(f), 2.4(k) and 3.6 hereof), in such Debentures, in an Officers' Certificate, or in a supplemental indenture authorizing or providing for the issue thereof.

Such right of conversion shall extend only to the maximum number of whole Common Shares into which the aggregate principal amount of the Debenture or Debentures surrendered for conversion at any one time by the holder thereof may be converted. Fractional interests in Common Shares shall be adjusted for in the manner provided in Section 6.6.

6.2

Notice of Expiry of Conversion Privilege

Notice of the expiry of the conversion privileges of the Debentures shall be given by or on behalf of the Corporation, not more than 60 days and not less than 40 days prior to the date fixed for the Time of Expiry, in the manner provided in Section 14.2.

6.3

Revival of Right to Convert

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

6.4

Manner of Exercise of Right to Convert

(a)

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

(b)

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

(c)

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

(d)

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

(e)

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

(f)

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

(g)

For the purposes of this Article, a Debenture shall be deemed to be surrendered for conversion on the date on which it is so surrendered when the register of the Trustee is open and in accordance with the provisions of this Article or, in the case of Uncertificated Debentures which the Trustee received notice of and all necessary documentation in respect of the exercise of the conversion rights and, in the case of a Debenture so surrendered by post or other means of transmission, on the date on which it is received by the Trustee at one of its 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 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 (in each case, called the "Date of Conversion").

(h)

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

(i)

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

(j)

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

6.5

Adjustment of Conversion Price

Subject to the requirements of the TSX (or such other recognized exchange on which the Debentures are then listed), the Conversion Price in effect at any date shall be subject to adjustment from time to time as set forth below.

(a)

If and whenever at any time prior to the Time of Expiry the Corporation shall: (i) subdivide or redivide the outstanding Common Shares into a greater number of shares; (ii) reduce, combine or consolidate the outstanding Common Shares into a smaller number of shares; or (iii) issue Common Shares to the holders of all or substantially all of the outstanding Common Shares by way of a dividend or distribution (other than the issue of Common Shares to holders of Common Shares who have elected to receive dividends or distributions in the form of Common Shares in lieu of cash dividends or cash distributions paid in the ordinary course on the Common Shares), the Conversion Price in effect on the effective date of such subdivision, redivision, reduction, combination or consolidation or on the record date for such issue of Common Shares by way of a dividend or distribution, as the case may be, shall in the case of any of the events referred to in (i) and (iii) above be decreased in proportion to the number of outstanding Common Shares resulting from such subdivision, redivision, dividend or distribution, 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 (b) and (c) 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 issuance of options, rights or warrants to all or substantially all the holders of its outstanding Common Shares (other than for 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) 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 Share on such record date (other than pursuant to a distribution reinvestment plan of the Corporation), 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 quotient obtained 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 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 readjusted 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 if only 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.

(c)

If and whenever at any time prior to the Time of Expiry the Corporation shall fix a record date for the making of a distribution to all or substantially all the holders of its outstanding Common Shares of: (i) shares of any class other than Common Shares and other than shares distributed to holders of Common Shares who have elected to receive dividends or distributions in the form of such shares in lieu of dividends or distributions paid in the ordinary course; (ii) rights, options or warrants (excluding rights, options or warrants for which any adjustment was made pursuant to Section 6.5(b) and rights, options or warrants entitling the holders thereof for a period of not more than 45 days to subscribe for or purchase Common Shares or securities convertible into Common Shares); (iii) evidences of its indebtedness; or (iv) assets (excluding dividends or distributions paid in the ordinary course) then, in each such case, 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 multiplied by the Current Market Price per Share on such record date, less the fair market value (as determined by the Directors, subject to TSX approval and with the approval of the Trustee, which determination shall be conclusive) of such shares or rights, options or warrants or evidences of indebtedness or assets so distributed, and of which the denominator shall be the total

number of Common Shares outstanding on such record date multiplied by such Current Market Price per Share. Such adjustment shall be made successively whenever such a record date is fixed. To the extent that such distribution is not so made, 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 such shares or rights, options or warrants or evidences of indebtedness or assets actually distributed, as the case may be. In clause (iv) of this subsection (c) the term "dividends or distributions paid in the ordinary course" shall include the value of any securities or other property or assets distributed in lieu of cash dividends or distributions paid in the ordinary course at the option of shareholders. 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 Ex-Dividend Date 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 one Spinoff Security or, if no such prices are available, the fair market value of one Spinoff Security as reasonably determined by the Board of Directors, subject to TSX approval (which determination shall be conclusive and shall be evidenced by an Officers' Certificate delivered to the Trustee) multiplied by (ii) the number of Spinoff Securities distributed in respect of one Common Share and the numerator of which shall be the weighted average trading price of one Common Share over the Spinoff Valuation Period, such adjustment to become effective immediately preceding the opening of business on the 25th trading day after the date on which ex-dividend trading commences; provided, however, that the Corporation may in lieu of the foregoing adjustment elect to make adequate provision so that each holder of Debentures shall have the right to receive upon conversion thereof the amount of such Spinoff Securities that such holder of Debentures would have received if such Debentures had been converted on the record date with respect to such distribution. In respect of any conversion during the Spinoff Valuation Period, references to consecutive trading days shall be deemed to be replaced with such lesser number of trading days as have elapsed between the Commencement of the Spinoff Valuation Period and the relevant conversion date.

(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 or change of the Common Shares other than as described in Section 6.5(a) or a consolidation, amalgamation, arrangement or merger of the Corporation with or into any other person or other entity; or a sale, transfer or other disposition of the property and assets of the Corporation as an entirety or substantially as an entirety to any other person 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, change, consolidation, amalgamation, arrangement or merger, sale, transfer, disposition 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, the number of shares or other securities or property of the Corporation or of the person or other entity resulting from such reclassification, capital reorganization, change, consolidation, amalgamation, arrangement or merger, or to which such sale, transfer, disposition may be made or which holders of Common Shares receive pursuant to such liquidation, dissolution or winding-up, as the case may be, that such holder of a Debenture would have been entitled to receive on such reclassification, capital reorganization, change, consolidation, amalgamation, arrangement or merger, sale, transfer, dispositions 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 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, change, consolidation, amalgamation, arrangement, merger, sale, transfer, dispositions or liquidation, dissolution or winding-up or other similar transaction, 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 shares or other securities or property to which a holder of Debentures is entitled on the exercise of its conversion rights thereafter. Any indenture entered into between the Corporation and the Trustee 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 Trustee 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, changes, consolidations, amalgamations, mergers, sales, transfers, dispositions and to any successive liquidation, dissolution or winding up or other similar transaction. For greater certainty, nothing in this Section 6.5(d) shall affect or reduce the requirement for any person to make a Debenture Offer or to pay the Make Whole Premium in accordance with Section 2.4, and notice of any transaction to which this Section 6.5(d) applies shall be given in accordance with Section 6.10.

(e)

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 it shall be equal to the price determined by multiplying the Conversion Price in effect on such record date by a fraction, of which the denominator shall be the Current Market Price per Share on such record date and of which the numerator shall be the Current Market Price per Share on such record date minus the amount in cash per Share distributed to holders of Common Shares. Such adjustment shall be made successively whenever such a record date is fixed. To the extent that any such cash dividend or distribution is not paid, the Conversion Price shall be re-adjusted to the Conversion Price which would then be in effect if such record date had not been fixed. For the avoidance of doubt, if and to the extent any adjustment pursuant to Sections 6.5(a), 6.5(b) and 6.5(c) is made, no adjustment to the Conversion Price pursuant to this Section 6.5(e) shall also be made. In this subsection (e) the term "dividends" or "distributions" shall include the value of any securities or other property or assets distributed in lieu of cash dividends or distributions paid in the ordinary course at the option of shareholders.

(f)

If any issuer bid (other than a normal course issuer bid made through the facilities of the TSX or such other exchange the Common Shares are listed and posted for trading on) made by the Corporation or any of its Subsidiaries for all or any portion of the Common Shares shall expire, then, if the issuer bid shall require the payment to shareholders who accept such bid 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 in respect of the Debentures shall be adjusted so that the same shall equal the price 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 numerator of which shall be the product of the number of Common Shares outstanding (including Purchased Common Shares (as defined below) 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; and (ii) the denominator shall be the sum of (A) the fair market value of the aggregate consideration (the fair market value being as determined by the directors of the Corporation, subject to TSX approval, if applicable, which determination shall be conclusive) 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 to the issuer bid 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, such adjustment to be 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 Section 6.5(f) to any issuer bid would result in an increase in the Conversion Price, no adjustment shall be made for such issuer bid pursuant hereto.

For purposes of this Section 6.5(f), the term "issuer bid" shall mean an issuer bid (other than an issuer bid which is exempt from the requirements of Part 2 of NI 62-104) under Applicable Securities Legislation or a take-over bid (other than a take-over bid which is exempt from the requirements of Part 2 of NI 62-104) under Applicable Securities Legislation by a Subsidiary of the Corporation for the Common Shares and all references to "purchases" of Common Shares in issuer bids (and all similar references) shall mean and include the purchase of Common Shares in issuer bids and all references to "tendered Common Shares" (and all similar references) shall mean and include Common Shares tendered in issuer bids.

(g)

In any case in which this Section 6.5 shall require that an adjustment shall become effective immediately after a record date for an event referred to herein, the Corporation may defer, until the occurrence of such event, issuing to the holder of any Debenture converted after such record date and before the occurrence of such event the additional Common Shares issuable upon such conversion by reason of the adjustment required by such event before giving effect to such adjustment; provided, however, that the Corporation shall deliver to such holder an appropriate instrument evidencing such holder's right to receive such additional Common Shares upon the occurrence of the event requiring such adjustment and the right to receive any distributions made on such additional Common Shares declared in favour of holders of record of Common Shares on and after the Date of Conversion or such later date as such holder would, but for the provisions of this Section 6.5(g), have become the holder of record of such additional Common Shares pursuant to Section 6.4(h).

(h)

The adjustments provided for in this Section 6.5 are cumulative and shall apply to successive subdivisions, redivisions, reductions, combinations, consolidations, distributions, issues or other events resulting in any adjustment under the provisions of this Section, provided that, notwithstanding any other provision of this Section, no adjustment of the Conversion Price shall be required unless such adjustment would require an increase or decrease of at least 1% in the Conversion Price then in effect; provided however, that any adjustments which by reason of this Section 6.5(h) 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 professional accountants appointed by the Corporation and acceptable to the Trustee (who may be the auditors of the Corporation); such accountants shall have access to all necessary records of the Corporation and such determination shall be binding upon the Corporation, the Trustee, and the Debentureholders.

(k)

In case the Corporation shall take any action affecting the Common Shares other than action described in this Section 6.5, which in the opinion of the 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 Directors, subject to the prior written consent of the TSX (or, if the Debentures are not listed thereon, on such other exchange on which the Debentures are then listed), as the 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 TSX 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) or 6.5(c) other than the events described in Sections 6.5(a)(i) or 6.5(a)(ii) if the holders of the Debentures are entitled to participate in such event on the same terms mutatis mutandis as if they had converted their Debentures prior to the effective date or record date, as the case may be, of such event.

(m)

Except as stated above in this Section 6.5, no adjustment will be made in the Conversion Price for any Debentures as a result of the issuance of Common Shares at less than the Current Market Price 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 or electronic deposit 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.

6.7

Corporation to Reserve Common Shares

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

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 shall be forthwith delivered to and cancelled by the Trustee 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 Trustee specifying the nature of the event requiring the same and the amount of the adjustment necessitated thereby and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based, which certificate and the amount of the adjustment specified therein shall be verified by an opinion of a firm of nationally recognized chartered accountants appointed by the Corporation and acceptable to the Trustee (who may be the Auditors of the Corporation) and shall be conclusive and binding on all parties in interest. When so approved, the Corporation shall, except in respect of any subdivision, redivision, reduction, combination or consolidation of the Common Shares, forthwith give notice to the Debentureholders in the manner provided in Section 14.2 specifying the event requiring such adjustment or readjustment and the results thereof, including the resulting Conversion Price.

6.10

Notice of Special Matters

The Corporation covenants with the Trustee that so long as any Debenture remains outstanding, it will give notice to the Trustee, and to the Debentureholders in the manner provided in Section 14.2, of its intention to fix a record date for any event referred to in Section 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 Trustee that so long as any Debenture remains outstanding, it will give notice to the Trustee, and to the Debentureholders in the manner provided in Section 14.2, at least 30 days prior to the (i) effective date of any transaction referred to in Section 6.5(d) stating the consideration into which the Debentures will be convertible after the effective date of such transaction, and (ii) the Expiration Date of any transaction referred to in Section 6.5(f) stating the consideration paid per Common Share in such transaction.

6.11

Protection of Trustee

Subject to Section 15.3, the Trustee:

(a)

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

(b)

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

(c)

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

6.12

Payment of Cash in Lieu of Common Shares

Upon conversion, the Corporation may offer and the converting holder may agree to the delivery of cash for all or a portion of the Debentures surrendered in lieu of Common Shares, the cash equivalent thereto to be determined on the basis of the Current Market Price of the Common Shares to be received upon conversion on the Date of Conversion (less applicable withholding taxes, if any).

Article 7
COVENANTS OF THE CORPORATION

The Corporation hereby covenants and agrees with the Trustee for the benefit of the Trustee and the Debentureholders, that so long as any Debentures remain outstanding:

7.1

To Pay Principal, Premium (if any) and Interest

7.7

Performance of Covenants by Trustee

If the Corporation shall fail to perform any of its covenants contained in this Indenture, the Trustee 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 Trustee shall be repayable as provided in Section 7.2. No such performance, expenditure or advance by the Trustee shall be deemed to relieve the Corporation of any default hereunder.

7.8

7.11

Restriction on Common Share Redemption Right and Common Share Repayment Right

The Corporation shall not, directly or indirectly (through a Subsidiary or otherwise) undertake or announce any rights offering, issuance of securities, subdivision of the Common Shares, dividend or other distribution on the Common Shares or any other securities, capital reorganization, reclassification or any similar type of transaction in which:

the number of securities to be issued;

Article 8

Each of the following events constitutes, and is herein referred to as, an "Event of Default":

(a)

failure for 30 days to pay interest on the Debentures when due;

(b)

failure to pay principal or premium (whether by way of payment of cash or delivery of Common Shares), if any, when due on the Debentures whether at maturity, upon redemption or a Change of Control, by declaration or otherwise;

(c)

(d)

default in the observance or performance of any covenant or condition of the Indenture by the Corporation and the failure to cure (or obtain a waiver for) such default for a period of 30 days after notice in writing has been given by the Trustee or from holders of not less than 25% in aggregate principal amount of the Debentures to the Corporation specifying such default and requiring the Corporation to rectify such default or obtain a waiver for same;

(e)

if a decree or order of a Court having jurisdiction is entered adjudging the Corporation or any Material Subsidiary a bankrupt or insolvent under the Bankruptcy and Insolvency Act (Canada) or any other bankruptcy, insolvency or analogous laws, or issuing sequestration or process of execution against, or against any substantial part of, the property of the Corporation or any Material Subsidiary, or appointing a receiver of, or of any substantial part of, the property of the Corporation or any Material Subsidiary or ordering the winding-up or liquidation of its affairs, and any such decree or order continues unstayed and in effect for a period of 60 days;

(f)

if the Corporation or any Material Subsidiary institutes proceedings to be adjudicated a bankrupt or insolvent, or consents to the institution of bankruptcy or insolvency proceedings against it under the Bankruptcy and Insolvency Act (Canada) or any other bankruptcy, insolvency or analogous laws, or consents to the filing of any such petition or to the appointment of a receiver of, or of any substantial part of, the property of the Corporation or any Material Subsidiary or makes a general assignment for the benefit of creditors, or admits in writing its inability to pay its debts generally as they become due;

(g)

if a resolution is passed for the winding-up or liquidation of the Corporation except in the course of carrying out or pursuant to a transaction in respect of which the conditions of Section 11.1 are duly observed and performed;

(h)

if, after the date of this Indenture, any proceedings with respect to the Corporation or any Material Subsidiary are taken with respect to a compromise or arrangement, with respect to creditors of the Corporation or any Material Subsidiary generally, under the applicable legislation of any jurisdiction; or

(i)

if an event of default occurs or exists under any indenture, agreement or other instrument evidencing or governing indebtedness for borrowed money (other than Non-Recourse Debt) of the Corporation or any Material Subsidiary and as a result of such event of default (i) indebtedness for borrowed money thereunder in excess of $10,000,000 (or the equivalent amount in any other currency) has become due and payable before the date it would otherwise have been due and payable and (ii) the holders of such indebtedness are entitled to commence, and have commenced, the enforcement of security they hold for such indebtedness (if any) or the exercise of any other creditors' remedies to collect such indebtedness;

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

8.2

Notice of Events of Default

If an Event of Default shall occur and be continuing the Trustee 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 Trustee shall have been requested to do so by the holders of at least 25% of the principal amount of the Debentures then outstanding, the Trustee shall not be required to give such notice if the Trustee 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.

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

8.3

Waiver of Default

Upon the happening of any Event of Default hereunder:

(a)

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

(b)

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

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

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 Trustee, 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 Trustee may in its 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 its name as trustee 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 Trustee in such request shall have been directed to take, or if such request contains no such direction, or if the Trustee shall act without such request, then by such proceedings authorized by this Indenture or by suit at law or in equity as the Trustee shall deem expedient.

The Trustee shall be entitled and empowered, either in its own name or as Trustee of an express trust, or as attorney-in-fact for the holders of the Debentures, or in any one or more of such capacities, to file such proof of debt, amendment of proof of debt, claim, petition or other document as may be necessary or advisable in order to have the claims of the Trustee and of the holders of the Debentures allowed in any insolvency, bankruptcy, liquidation or other judicial proceedings relative to the Corporation or its creditors or relative to or affecting its property. The Trustee is hereby irrevocably appointed (and the successive respective holders of the Debentures by taking and holding the same shall be conclusively deemed to have so appointed the Trustee) the true and lawful attorney-in-fact of the respective holders of the Debentures with authority to make and file in the respective names of the holders of the Debentures or on behalf of the holders of the Debentures as a class, subject to deduction from any such claims of the amounts of any claims filed by any of the holders of the Debentures themselves, any proof of debt, amendment of proof of debt, claim, petition or other document in any such proceedings and to receive payment of any sums becoming distributable on account thereof, and to execute any such other papers and

documents and to do and perform any and all such acts and things for and on behalf of such holders of the Debentures, as may be necessary or advisable in the opinion of the Trustee, in order to have the respective claims of the Trustee and of the holders of the Debentures against the Corporation or its property allowed in any such proceeding, and to receive payment of or on account of such claims; provided, however, that subject to Section 8.3, nothing contained in this Indenture shall be deemed to give to the Trustee, unless so authorized by Extraordinary Resolution, any right to accept or consent to any plan of reorganization or otherwise by action of any character in such proceeding to waive or change in any way any right of any Debentureholder.

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

All rights of action hereunder may be enforced by the Trustee without the possession of any of the Debentures or the production thereof on the trial or other proceedings relating thereto. Any such suit or proceeding instituted by the Trustee shall be brought in the name of the Trustee as trustee of an express trust, and any recovery of judgment shall be for the rateable benefit of the holders of the Debentures subject to the provisions of this Indenture. In any proceeding brought by the Trustee (and also any proceeding in which a declaratory judgment of a court may be sought as to the interpretation or construction of any provision of this Indenture, to which the Trustee shall be a party) the Trustee shall be held to represent all the holders of the Debentures, and it shall not be necessary to make any holders of the Debentures parties to any such proceeding.

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, premium (if any) 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 Trustee 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 Trustee and the Trustee shall have been afforded reasonable opportunity either itself 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 Trustee, when so requested by the Trustee, sufficient funds and security and indemnity satisfactory to it against the costs, expenses and liabilities to be incurred therein or thereby; and (d) the Trustee shall have failed to act within a reasonable time after such notification, request and offer of indemnity and such notification, request and offer of indemnity are hereby declared in every such case, at the option of the Trustee, to be conditions precedent to any such proceeding or for any other remedy hereunder by or on behalf of the holder of any Debentures.

8.6

Application of Monies by Trustee

(a)

Except as herein otherwise expressly provided, any monies received by the Trustee from the Corporation pursuant to the foregoing provisions of 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 Trustee available for such purpose, as follows:

(i)

first, in payment or in reimbursement to the Trustee of its compensation, costs, charges, expenses, borrowings, advances or other monies furnished or provided by or at the instance of the Trustee in or about the execution of its trusts under, or otherwise in relation to, this Indenture, 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 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.

(b)

The Trustee shall not be bound to apply or make any partial or interim payment of any monies coming into its hands if the amount so received by it, after reserving thereout such amount as the Trustee may think necessary to provide for the payments mentioned in 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 15.9 until the money or the investments representing the same, with the income derived therefrom, together with any other monies for the time being under its control shall be sufficient for the said purpose or until it shall consider it advisable to apply the same in the manner hereinbefore set forth. The foregoing shall, however, not apply to a final payment in distribution hereunder.

8.7

Notice of Payment by Trustee

Not less than 15 days' notice shall be given in the manner provided in Section 14.2 by the Trustee 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.

8.8

Trustee May Demand Production of Debentures

The Trustee 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 Trustee may, in its discretion, dispense with such production and endorsement, upon such indemnity being given to it and to the Corporation as the Trustee shall deem sufficient.

8.9

Remedies Cumulative

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

8.10

Judgment Against the Corporation

The Corporation covenants and agrees with the Trustee 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 Trustee, as trustee 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.

8.11

Immunity of Directors, Officers and Others

Article 10
COMMON SHARE INTEREST PAYMENT ELECTION

10.1

Common Share Interest Payment Election

(a)

Subject to the provisions of any series of Debentures, and provided that no Event of Default has occurred and is continuing and that all applicable regulatory approvals have been obtained (including any required approval of any stock exchange on which the Debentures or Common Shares are then listed), the Corporation shall have the right, from time to time (including following conversion, at the time of redemption or at the time of maturity), to make a Common Share Interest Payment Election in respect of any Interest Obligation by delivering a Common Share Interest Payment Election Notice to the Trustee no later than the earlier of (i) the date required by applicable law or the rules of any stock exchange on which the Debentures or Common Shares are then listed, and (ii) the day which is 15 Business Days prior to the Interest Payment Date to which the Common Share Interest Payment Election relates. Such Common Share Interest Payment Election Notice shall provide that all or a portion of the Interest Obligation may be paid by the Corporation in Common Shares by the delivery of Common Shares to the Trustee and the subsequent sale of such Common Shares by the Trustee in accordance with this Section 10.1, and if only a portion of the Interest Obligation is to be paid in Common Shares, the Common Share Interest Payment Election shall state such portion to be paid in Common Shares and such portion to be paid in cash.

(b)

Upon receipt of a Common Share Interest Payment Election Notice, the Trustee shall, in accordance with this Article 10 and such Common Share Interest Payment Election Notice, deliver Common Share Bid Requests to the investment banks, brokers or dealers identified by the Corporation, in its absolute discretion, in the Common Share Interest Payment Election Notice. In connection with the Common Share Interest Payment Election, the Trustee shall have the power to: (i) accept delivery of the Common Shares from the Corporation and process the Common Shares in accordance with the Common Share Interest Payment Election Notice; (ii) accept bids with respect to, and consummate sales of, such Common Shares, each as the Corporation shall direct in its absolute discretion through the investment banks, brokers or dealers identified by the Corporation in the Common Share Interest Payment Election Notice; (iii) invest the proceeds of such sales on the direction of the Corporation in Government Obligations which mature prior to an applicable Interest Payment Date and use such proceeds to pay the Interest Obligation in respect of which the Common Share Interest Payment Election was made; (iv) deliver proceeds to holders of Debentures that together with the additional cash payments of the Corporation, if any, will satisfy all of the Corporation's Interest Obligations, as directed by the Corporation in the Common Share Interest Payment Election Notice, and (v) perform any other action necessarily incidental thereto as directed by the Corporation in its absolute discretion. The Common Share Interest Payment Election Notice shall direct the Trustee to solicit and accept only, and each Common Share Bid Request shall provide that the acceptance of any bid is conditional on the acceptance of, sufficient bids to result in aggregate proceeds from such issue and sale of Common Shares which, together with the cash payments by the Corporation in lieu of fractional Common Shares, if any, equal the Interest Obligation on the Common Share Delivery Date.

(c)

The Common Share Interest Payment Election Notice shall provide for, and all bids shall be subject to, the right of the Corporation, by delivering written notice to the Trustee at any time prior to the consummation of such delivery and sale of the Common Shares on the Common Share Delivery Date, to withdraw (in whole or in part) the Common Share Interest Payment Election (which shall have the effect of withdrawing each related Common Share Bid Request), whereupon the Corporation shall be obliged to pay in cash the Interest Obligation in respect of which the Common Share Interest Payment Election Notice has been delivered and subsequently withdrawn.

(d)

Any sale of Common Shares pursuant to this Article 10 may be made to one or more Persons whose bids are solicited, but all such sales with respect to a particular Common Share Interest Payment Election shall take place concurrently on the Common Share Delivery Date.

(e)

The amount received by a holder of a Debenture in respect of the Interest Obligation or the entitlement thereto will not be affected by whether or not the Corporation elects to satisfy the Interest Obligation pursuant to a Common Share Interest Payment Election.

(f)

The Trustee shall inform the Corporation promptly following receipt of any bid or bids for Common Shares solicited pursuant to the Common Share Bid Requests. The Trustee 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 and other cash payments by the Corporation, 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 Trustee (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, 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 Trustee.

(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 Common Share Delivery Date, deliver to the Trustee 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 Trustee shall consummate such sales on such Common Share Delivery Date by the delivery of the Common Shares to such purchasers against payment to the Trustee 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 Trustee out of the proceeds of such sales of Common Shares plus any amount received by the Trustee 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 Trustee 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 Trustee is 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 Trustee) (the "Interest Account") for such Debentures. The Trustee 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 Trustee 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 Trustee shall pay the funds held in the Interest Account, together with additional cash payments of the Corporation, if any, to the holders of record of the Debentures on the Interest Payment Date (less any tax required to be deducted, if any) 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 equal to the market price of such fractional interest (less any tax required to be deducted, if any).

in the case of action taken or power exercised by instrument in writing under Section 13.15, 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.

(c)

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 13.15, 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 Trustee and the Corporation for all purposes hereof.

(d)

A proposal:

(i)

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;

(ii)

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

(iii)

to reduce with respect to Debentureholders of any particular series any percentage stated in this Section 13.2 or Sections 13.4, 13.12 and 13.15;

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

13.3

Chairman

Some person, who need not be a Debentureholder, nominated in writing by the Corporation (in case it convenes the meeting) or by the Trustee (in any other case) 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 is 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.

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 Corporation (in case it convenes the meeting) or the Trustee (in any other case) for the purpose of enabling the Debentureholders to be present and vote at any meeting without producing their Debentures, and of enabling them to be present and vote at any such meeting by proxy and of lodging instruments appointing such proxies at some place other than the place where the meeting is to be held, may from time to time make and vary such regulations as it shall think fit providing for and governing any or all of the following matters:

(a)

the form of the instrument appointing a proxy, which shall be in writing, and the manner in which the same shall be executed and the production of the authority of any person signing on behalf of a Debentureholder;

(b)

the deposit of instruments appointing proxies at such place as the Trustee, the 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; and

(c)

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

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.

13.10

Persons Entitled to Attend Meetings

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

13.11

Powers Exercisable by Extraordinary Resolution

In addition to the powers conferred upon them by any other provisions of this Indenture or by law, a meeting of the Debentureholders shall have the following powers exercisable from time to time by Extraordinary Resolution, subject in the case of the matters in paragraphs (a), (b), (c), (d) and (l) to receipt of the prior approval of the TSX (or such other exchange on which the Debentures are then listed):

(b)

(c)

(e)

power to direct or authorize the Trustee to exercise any power, right, remedy or authority given to it by this Indenture in any manner specified in any such Extraordinary Resolution or to refrain from exercising any such power, right, remedy or authority;

The resolution making such appointment may provide for payment of the expenses and disbursements of and compensation to such committee. Such committee shall consist of such number of persons as shall be prescribed in the resolution appointing it and the members need not be themselves Debentureholders. Every such committee may elect its chairman and may make regulations respecting its quorum, the calling of its meetings and the filling of vacancies occurring in its number and its procedure generally. 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. All acts of any such committee within the authority delegated to it shall be binding upon all Debentureholders. Neither the committee nor any member thereof shall be liable for any loss arising from or in connection with any action taken or omitted to be taken by them in good faith;

(k)

power to remove the Trustee from office and to appoint a new Trustee or Trustees provided that no such removal shall be effective unless and until a new Trustee or Trustees shall have become bound by this Indenture;

Notwithstanding the foregoing provisions of this Section 13.11 none of such provisions shall in any manner allow or permit any amendment, modification, abrogation or addition to the provisions of Article 5 which could reasonably be expected to detrimentally affect the rights, remedies or recourse of the priority of the Senior Creditors.

13.12

Meaning of "Extraordinary Resolution"

(a)

The expression "Extraordinary Resolution" when used in this Indenture means, subject as hereinafter in this Article provided, a resolution proposed to be passed as an Extraordinary Resolution at a meeting of Debentureholders (including an adjourned meeting) duly convened for the purpose and held in accordance with the provisions of this Article at which the holders of not less than 25% of the principal amount of the

Debentures then outstanding, and if the meeting is a Serial Meeting, at which holders of not less than 25% of the principal amount of the Debentures then outstanding of each especially affected series, are present in person or by proxy and passed by the favourable votes of the holders of not less than 66 2/3% of the principal amount of the Debentures, and if the meeting is a Serial Meeting by the affirmative vote of the holders of not less than 66 2/3% of each especially affected series, in each case present or represented by proxy at the meeting and voted upon on a poll on such resolution.

(b)

If, at any such meeting, the holders of not less than 25% of the principal amount of the Debentures then outstanding and, if the meeting is a Serial Meeting, 25% of the principal amount of the Debentures then outstanding of each especially affected series, in each case are not present in person or by proxy within 30 minutes after the time appointed for the meeting, then the meeting, if convened by or on the requisition of Debentureholders, shall be dissolved but in any other case it shall stand adjourned to such date, being not less than 14 nor more than 60 days later, and to such place and time as may be appointed by the chairman. Not less than 10 days' notice shall be given of the time and place of such adjourned meeting in the manner provided in Section 14.2. Such notice shall state that at the adjourned meeting the Debentureholders present in person or by proxy shall form a quorum. At the adjourned meeting the Debentureholders present in person or by proxy shall form a quorum and may transact the business for which the meeting was originally convened and a resolution proposed at such adjourned meeting and passed thereat by the affirmative vote of holders of not less than 66 2/3% of the principal amount of the Debentures and, if the meeting is a Serial Meeting, by the affirmative vote of the holders of not less than 66 2/3% of the principal amount of the Debentures of each especially affected series, in each case present or represented by proxy at the meeting voted upon on a poll shall be an Extraordinary Resolution within the meaning of this Indenture, notwithstanding that the holders of not less than 25% in principal amount of the Debentures then outstanding, and if the meeting is a Serial Meeting, holders of not less than 25% of the principal amount of the Debentures then outstanding of each especially affected series, are not present in person or by proxy at such adjourned meeting.

(c)

Votes on an Extraordinary Resolution shall always be given on a poll and no demand for a poll on an Extraordinary Resolution shall be necessary.

13.13

Powers Cumulative

Any one or more of the powers in this Indenture stated to be exercisable by the Debentureholders by Extraordinary Resolution or otherwise may be exercised from time to time and the exercise of any one or more of such powers from time to time shall not be deemed to exhaust the rights of the Debentureholders to exercise the same or any other such power or powers thereafter from time to time.

13.14

Minutes

Minutes of all resolutions and proceedings at every meeting as aforesaid shall be made and duly entered in books to be from time to time provided for that purpose by the Trustee at the expense of the Corporation, and any such minutes as aforesaid, if signed by the chairman of the meeting at which such resolutions were passed or proceedings had, or by the chairman of the next succeeding meeting of the Debentureholders, shall be prima facie evidence of the matters therein stated and, until the contrary is proved, every such meeting, in respect of the proceedings of which minutes shall have been made, shall be deemed to have been duly held and convened, and all resolutions passed thereat or proceedings taken thereat to have been duly passed and taken.

13.15

Instruments in Writing

All actions which may be taken and all powers that may be exercised by the Debentureholders at a meeting held as hereinbefore in this Article provided may also be taken and exercised by the holders of 66 2/3% of the principal amount of all the outstanding Debentures and, if the meeting at which such actions might be taken would be a Serial Meeting, by the holders of 66 2/3% of the principal amount of the Debentures then outstanding of each especially affected series, by an instrument in writing signed in one or more counterparts and the expression "Extraordinary Resolution" when used in this Indenture shall include an instrument so signed.

13.16

Binding Effect of Resolutions

Every resolution and every Extraordinary Resolution passed in accordance with the provisions of this Article at a meeting of Debentureholders shall be binding upon all the Debentureholders, whether present at or absent from such meeting, and every instrument in writing signed by Debentureholders in accordance with Section 13.15 shall be binding upon all the Debentureholders, whether signatories thereto or not, and each and every Debentureholder and the Trustee (subject to the provisions for its indemnity herein contained) shall be bound to give effect accordingly to every such resolution, Extraordinary Resolution and instrument in writing.

13.17

Evidence of Rights Of Debentureholders

(a)

Any request, direction, notice, consent or other instrument which this Indenture may require or permit to be signed or executed by the Debentureholders may be in any number of concurrent instruments of similar tenor signed or executed by such Debentureholders.

(b)

The Trustee may, in its discretion, require proof of execution in cases where it deems proof desirable and may accept such proof as it shall consider proper.

13.18

Concerning Serial Meetings

If in the opinion of Counsel any business to be transacted at any meeting, or any action to be taken or power to be exercised by instrument in writing under Section 13.15, does not adversely affect the rights of the holders of Debentures of one or more series, the provisions of this Article 13 shall apply as if the Debentures of such series were not outstanding and no notice of any such meeting need be given to the holders of Debentures of such series. Without limiting the generality of the foregoing, a proposal to modify or terminate any covenant or agreement which is effective only so long as Debentures of a particular series are outstanding shall be deemed not to adversely affect the rights of the holders of Debentures of any other series.

Article 14

14.2

Notice to Debentureholders

Subject to Section 2.6, all notices to be given hereunder with respect to the Debentures shall be deemed to be validly given to the holders thereof if sent by first class mail, postage prepaid, by letter or circular addressed to such holders at their post office addresses appearing in any of the registers hereinbefore mentioned and shall be deemed to have been effectively given three days following the day of mailing; provided that any for any Debentures held through CDS or other Depository, if any notice or other communication is required to be given to Debentureholders, the Trustee or the Corporation may give such notices and communications to CDS or such other Depository by e-mail or facsimile (at such e-mail or facsimile number as is given by CDS or the Depository, as applicable, for such purpose from time to time) or in such other manner as is acceptable to CDS or the Depository, as applicable, and notice will deemed to have been effective/given on the date of delivery. Accidental error or omission in giving notice or accidental failure to mail notice to any Debentureholder or the inability of the Corporation to give or mail any notice due to anything beyond the reasonable control of the Corporation shall not invalidate any action or proceeding founded thereon. Accidental error or omission in giving notice or accidental failure to mail notice to any Debentureholder or the inability of the Corporation to give or mail any notice due to anything beyond the reasonable control of the Corporation shall not invalidate any action or proceeding founded thereon.

If any notice given in accordance with the foregoing paragraph would be unlikely to reach the Debentureholders to whom it is addressed in the ordinary course of post by reason of an interruption in mail service, whether at the place of dispatch or receipt or both, the Corporation shall give such notice by publication at least once in the cities of Calgary and Toronto (or in such of those cities as, in the opinion of the Trustee, is sufficient in the particular circumstances), each such publication to be made in a daily newspaper of general circulation in the designated city.

Any notice given to Debentureholders by publication shall be deemed to have been given on the day on which publication shall have been effected at least once in each of the newspapers in which publication was required.

All notices with respect to any Debenture may be given to whichever one of the holders thereof (if more than one) is named first in the registers hereinbefore mentioned, and any notice so given shall be sufficient notice to all holders of any persons interested in such Debenture.

Article 15
CONCERNING THE TRUSTEE

15.1

No Conflict of Interest

The Trustee represents to the Corporation that at the date of execution and delivery by it of this Indenture there exists no material conflict of interest in the role of the Trustee as a fiduciary hereunder but if, notwithstanding the provisions of this Section 15.1, such a material conflict of interest exists, or hereafter arises, the validity and enforceability of this Indenture, and the Debentures issued hereunder, shall not be affected in any manner whatsoever by reason only that such material conflict of interest exists or arises but the Trustee shall, within 30 days after ascertaining that it has a material conflict of interest, either eliminate such material conflict of interest or resign in the manner and with the effect specified in Section 15.2.

15.2

Replacement of Trustee

The Trustee may resign its trust and be discharged from all further duties and liabilities hereunder by giving to the Corporation 90 days' notice in writing or such shorter notice as the Corporation may accept as sufficient. If at any time a material conflict of interest exists in the Trustee's role as a fiduciary hereunder the Trustee shall, within 30 days after ascertaining that such a material conflict of interest exists, either eliminate such material conflict of interest or resign in the manner and with the effect specified in this Section 15.2. The validity and enforceability of this Indenture and of the Debentures issued hereunder shall not be affected in any manner whatsoever by reason only that such a material conflict of interest exists. In the event of the Trustee resigning or being removed or being dissolved, becoming bankrupt, going into liquidation or otherwise becoming incapable of acting hereunder, the Corporation shall forthwith appoint a new Trustee unless a new Trustee has already been appointed by the Debentureholders. Failing such appointment by the Corporation, the retiring Trustee or any

Debentureholder may apply to a Judge of the Court of Queen's Bench of Alberta, on such notice as such Judge may direct at the Corporation's expense, for the appointment of a new Trustee but any new Trustee so appointed by the Corporation or by the Court shall be subject to removal as aforesaid by the Debentureholders and the appointment of such new Trustee shall be effective only upon such new Trustee becoming bound by this Indenture. Any new Trustee appointed under any provision of this Section 15.2 shall be a corporation authorized to carry on the business of a trust company in all of the Provinces of Canada. On any new appointment the new Trustee shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Trustee.

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

15.3

Duties of Trustee

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

15.4

Reliance Upon Declarations, Opinions, etc.

In the exercise of its rights, duties and obligations hereunder the Trustee may, if acting in good faith, rely, as to the truth of the statements and accuracy of the opinions expressed therein, upon statutory declarations, opinions, reports or certificates furnished pursuant to any covenant, condition or requirement of this Indenture or required by the Trustee to be furnished to it in the exercise of its rights and duties hereunder, if the Trustee examines such statutory declarations, opinions, reports or certificates and determines that they comply with Section 15.5, if applicable, and with any other applicable requirements of this Indenture. The Trustee may nevertheless, in its discretion, require further proof in cases where it deems further proof desirable. Without restricting the foregoing, the Trustee may rely on an opinion of Counsel satisfactory to the Trustee notwithstanding that it is delivered by a solicitor or firm which acts as solicitors for the Corporation.

15.5

Evidence and Authority to Trustee, Opinions, etc.

The Corporation shall furnish to the Trustee evidence of compliance with the conditions precedent provided for in this Indenture relating to any action or step required or permitted to be taken by the Corporation or the Trustee under this Indenture or as a result of any obligation imposed under this Indenture, including without limitation, the Authentication and delivery of Debentures hereunder, the satisfaction and discharge of this Indenture and the taking of any other action to be taken by the Trustee at the request of or on the application of the Corporation, forthwith if and when (a) such evidence is required by any other Section of this Indenture to be furnished to the Trustee in accordance with the terms of this Section 15.5, or (b) the Trustee, in the exercise of its rights and duties under this Indenture, gives the Corporation written notice requiring it to furnish such evidence in relation to any particular action or obligation specified in such notice.

Such evidence shall consist of:

(a)

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

(b)

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

(c)

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

Whenever such evidence relates to a matter other than the Authentication and delivery of Debentures and the satisfaction and discharge of this Indenture, and except as otherwise specifically provided herein, such evidence may consist of a report or opinion of any solicitor, auditor, accountant, engineer or appraiser or any other person whose qualifications give authority to a statement made by him, provided that if such report or opinion is furnished by a director, officer or employee of the Corporation it shall be in the form of a statutory declaration. Such evidence shall be, so far as appropriate, in accordance with the immediately preceding paragraph of this Section.

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

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

15.6

Officers' Certificates Evidence

Except as otherwise specifically provided or prescribed by this Indenture, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, the Trustee, if acting in good faith, may rely upon an Officers' Certificate.

15.7

Experts, Advisers and Agents

The Trustee may:

(a)

Anti-Money Laundering

The Trustee shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Trustee, in its sole judgment, acting reasonably, determines that such act might cause it to be in noncompliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline.

BELLATRIX EXPLORATION LTD.

(A corporation incorporated under the laws of Alberta)

6.75% Extendible CONVERTIBLE UNSECURED SUBORDINATED DEBENTURE

Bellatrix Exploration Ltd. (the "Corporation" or the "Issuer") for value received hereby acknowledges itself indebted and, subject to the provisions of the debenture indenture (the "Indenture") dated as of August 9, 2016 between the Corporation and Computershare Trust Company of Canada (the "Trustee"), promises to pay to the registered holder hereof on the Initial Maturity Date or the Final Maturity Date, as applicable, or on such earlier date as the principal amount hereof may become due in accordance with the provisions of the Indenture the principal sum of · Dollars ($ · ) in lawful money of Canada on presentation and surrender of this Initial Debenture at the main branch of the Trustee in Calgary, Alberta or in Toronto, Ontario 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 rate of 6.75% per annum (based on a year of 365 days), in like money, in arrears in (with the exception of the first interest payment which will include interest from August 9, 2016 as set forth below) semi-annual installments (less any tax required by law to be deducted) on March 31 and September 30 in each year commencing on September 30, 2016 (unless the Initial Maturity Date occurs prior to such date in which case the first interest payment shall fall due on the Initial Maturity Date) and, assuming maturity of the Initial Debentures is extended to the Final Maturity Date, the last payment (representing interest payable from the Interest Payment Date immediately prior to the Final Maturity Date to, but excluding, the Final Maturity Date) to fall due on the Final 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 and including the date of closing of the Initial Debenture Offering to, but excluding, September 30, 2016, which will be equal to $ · for each $1,000 principal amount of Initial Debentures; provided that if the Maturity Date of the Initial Debentures is not extended to the Final Maturity Date and the Initial Maturity Date occurs prior to September 30, 2016 the first interest payment will include interest accrued from the closing of the Initial Debenture Offering to, but excluding, the Initial Maturity Date. Any payment required to be made on any day that is not a Business Day will be made on the next succeeding Business Day.

The Corporation may elect, from time to time, to satisfy interest hereon by delivering: (i) cash; (ii) freely tradeable Common Shares; or (iii) a combination of (i) and (ii), to the Trustee pursuant to the Common Share Interest Payment Election and delivery of such cash or freely tradeable Common Shares, or any combination thereof less the amount of any tax required to be withheld, shall satisfy and discharge all liability for interest on this Initial Debenture to the extent of the sum represented thereby plus any tax withheld as aforesaid.

A-2

This Initial Debenture is one of the 6.75% Extendible 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 $57,500,000 in lawful money of Canada. Reference is hereby expressly made to the Indenture for a description of the terms and conditions upon which the Initial Debentures are or are to be issued and held and the rights and remedies of the holders of the Initial Debentures and of the Corporation and of the Trustee, all to the same effect as if the provisions of the Indenture were herein set forth to all of which provisions the holder of this Initial Debenture by acceptance hereof assents.

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

Any part, being $1,000 or an integral multiple thereof, of the principal of this Initial Debenture, provided that the principal amount of this Initial Debenture is in a denomination in excess of $1,000, is convertible, at the option of the holder hereof, upon surrender of this Initial Debenture at the principal office of the Trustee in Calgary, Alberta or in Xxxxxxx, Xxxxxxx, at any time following the Disposition Closing and prior to the close of business on the last 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 last Business Day immediately preceding the date specified for redemption of this Initial Debenture or, if called for repurchase pursuant to the 90% Redemption Right on the Business Day immediately prior to the payment date, or, if subject to compulsory acquisition as provided for in the Indenture, on the Business Day immediately prior to the day on which such acquisition becomes effective, 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 $1.62 (the "Conversion Price") per Common Share, being a rate of approximately 617.2840 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 March 31 and September 30 in each year, commencing September 30, 2016, as the registers of the Trustee will be closed during such periods. The Indenture makes provision for the adjustment of the Conversion Price in the events therein specified. No fractional Common Shares will be issued on any conversion but in lieu thereof, the Corporation will satisfy such fractional interest by a cash payment equal to the market price of such fractional interest determined in accordance with the Indenture. Holders converting their Debentures will receive accrued and unpaid interest thereon. If a Debenture is surrendered for conversion on an Interest Payment Date or during the five preceding Business Days, the person or persons entitled to receive Common Shares in respect of the Debentures so surrendered for conversion shall not become the holder or holders of record of such Common Shares until the Business Day following such Interest Payment Date.

This Initial Debenture may be redeemed at the option of the Corporation on the terms and conditions set out in the Indenture at the Redemption Price therein and herein set out provided that this Initial Debenture is not redeemable before September 30, 2019, except in the event of the satisfaction of certain conditions after a Change of Control has occurred. On and after September 30, 2019 and prior to September 30, 2020, and provided that the Current Market Price of the Common Shares is at least 125% of the Conversion Price of the Initial Debentures, the Initial Debentures are redeemable at the option of the Corporation at a price equal to $1,000 per Initial Debenture (the "Redemption Price") plus accrued and unpaid interest and otherwise on the terms and conditions described in the Indenture. On or after September 30, 2020 and prior to the Maturity Date, the Debentures may be redeemed by the Corporation, in whole or in part, from time to time at the Redemption Price plus accrued and unpaid interest and otherwise on the terms and conditions described in the Indenture. 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 principal portion of the Redemption Price by the issue of that number of Common Shares obtained by dividing the applicable principal portion of the Redemption Price by 95% of the volume weighted average trading price of the Common Shares on the TSX (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.

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 "Debenture Offer"). If 90% or more of the principal amount of all Debentures outstanding on the date the Corporation provides notice of the Change of Control to the Trustee have been tendered for purchase pursuant to the Debenture Offer, the Corporation has the right to redeem all the remaining outstanding Initial Debentures on the same date and at the same price.

A-3

In addition to the requirement for the Corporation to make a Debenture Offer in the event of a Change of Control, if 10% or more of the consideration for the Common Shares in the transaction or transactions constituting the Change of Control consists of:

(i)

cash, other than cash payments for fractional Common Shares and cash payments made in respect of dissenter's appraisal rights;

(ii)

equity securities that are not traded or intended to be traded immediately following such transactions on a recognized stock exchange; or

(iii)

other property that is not traded or intended to be traded immediately following such transactions on a recognized stock exchange,

then subject to regulatory approvals, during the period beginning 10 trading days before the anticipated date on which the Change of Control becomes effective and ending 30 days after the Debenture Offer is delivered, holders of Debentures will be entitled to convert their Debentures, subject to certain limitations, and receive, in addition to the number of Common Shares they would otherwise be entitled to receive, an additional number of Common Shares per $1,000 principal amount of Debentures calculated in accordance with the terms of the Indenture.

If an Offer for all of the outstanding Initial Debentures (other than the Offeror's Debentures) is made 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.

Subject to the receipt of any required regulatory approvals and to the restrictions on the Common Share Redemption Right and the Common Share Repayment Right, the Corporation may, on notice as provided in the Indenture, at its option and subject to any applicable regulatory approval, elect to satisfy the obligation to repay all or any portion of the principal amount of this Initial Debenture due on the Final Maturity 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 such other exchange on which the Debentures are then listed) for the 20 consecutive trading days ending five trading days before the Final Maturity Date. The Corporation will not be entitled to issue Common Shares to satisfy our payment obligations on the Initial Maturity Date.

(a) the number of securities to be issued;

(b) the price at which securities are to be issued, converted or exchanged; or

A-4

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.

The Indenture contains provisions making binding upon all holders of Debentures outstanding thereunder (or in certain circumstances specific series of Debentures) resolutions passed at meetings of such holders held in accordance with such provisions and instruments signed by the holders of a specified majority of Debentures outstanding (or specific series), which resolutions or instruments may have the effect of amending the terms of this 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 Trustee in the City of Calgary or the City of Toronto and in such other place or places and/or by such other registrars (if any) as the Corporation with the approval of the Trustee may designate. No transfer of this Initial Debenture shall be valid unless made on the register by the registered holder hereof or his executors or administrators or other legal representatives, or his or their attorney duly appointed by an instrument in form and substance satisfactory to the Trustee or other registrar, and upon compliance with such reasonable requirements as the Trustee and/or other registrar may prescribe and upon surrender of this Initial Debenture for cancellation. Thereupon a new Initial Debenture or Initial Debentures in the same aggregate principal amount shall be issued to the transferee in exchange hereof.

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

If any of the provisions of this Initial Debenture are inconsistent with the provisions of the Indenture, the provisions of the Indenture shall take precedence and shall govern. Capitalized words or expressions used in this Initial Debenture shall, unless otherwise defined herein, have the meaning ascribed thereto in the Indenture.

The Indenture and this Debenture shall be governed by, and construed in accordance with, the laws of the Province of Alberta and the federal laws of Canada applicable therein.

IN WITNESS WHEREOF BELLATRIX EXPLORATION LTD. has caused this Debenture to be signed by its authorized representatives as of the 9^th day of August, 2016.
