The first series of Debentures (the “Initial Debentures”) authorized for issue immediately is limited to an aggregate principal amount of $57,500,000 and shall be designated as “6% Convertible Unsecured Subordinated Debentures”.

The Initial Debentures shall be dated as of July 19, 2012, regardless of their actual date of issue, shall mature on June 30, 2017 and shall bear interest from July 19, 2012 at the rate of 6% per annum, payable in equal semiannual payments on June 30 and December 31 in each year, except the first payment, which shall be made on December 31, 2012, and which shall include accrued and unpaid interest for the period from and including July 19, 2012 to but excluding December 31, 2012 ($27.12 per $1,000 principal amount of Initial Debentures) and the last such payment shall fall due on June 30, 2017, 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 and calculated based on a 365day year. On or before 11:00 a.m. (Toronto time) on the Business Day prior to the date any payment is to be made, the Corporation shall provide the Trustee with a Written Direction of the Corporation specifying the payments to be made. The Trustee shall not be responsible for calculating the amount of interest owing, but shall be entitled to rely absolutely on the Written Direction of the Corporation specifying the payments to be made.

The Initial Debentures will be redeemable by the Corporation in accordance with the terms of Article 4, provided that the Initial Debentures will not be redeemable before June 30, 2014, except in the event of the satisfaction of certain conditions after a Change of Control has occurred as outlined herein. On and after June 30, 2014 and prior to June 30, 2017, the Initial Debentures may be redeemed in whole at any time 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 for the Initial Debentures equal to their principal amount provided that the Current Market Price immediately preceding the date on which such notice of redemption is given is not less than 130% of the Conversion Price and the Corporation shall have provided to the Trustee an Officer’s Certificate confirming such Current Market Price. The Redemption Notice for the Initial Debentures shall be in the form of Schedule B. Holders of the Initial Debentures being redeemed shall be entitled to receive, in addition to the Redemption Price, accrued and unpaid interest in respect thereof for the period up to but excluding the Redemption Date from and including the latest Interest Payment Date.

The Initial Debentures will be subordinated to the Senior Indebtedness of the Corporation in accordance with the provisions of Article 5; provided, however, that nothing contained in this Indenture shall in any way or manner restrict the Corporation from incurring, directly or indirectly, any additional indebtedness, including indebtedness that ranks senior to the Debentures, or from mortgaging, pledging or charging real or personal property or properties of the Corporation or its Subsidiaries, if any, to secure any indebtedness.

The Corporation will use reasonable commercial efforts to cause the Initial Debentures be listed and posted for trading on the TSX on November 20, 2012, such listing to be maintained so long as any such Initial Debentures remain outstanding and to maintain its status as a reporting issuer (or the equivalent thereof) in Alberta, British Columbia and Ontario not in default of Applicable Securities Legislation.

Upon and subject to the provisions and conditions of Article 6, the holder of each Initial Debenture shall have the right, at such holder’s option, at any time prior to 5:00 p.m. (Toronto time) on the earlier of the last Business Day immediately preceding the Maturity Date and the last Business Day immediately preceding the date specified by the Corporation for redemption of the Initial Debentures by notice to the holders of Initial Debentures in accordance with Section 2.4(c) and Section 4.3 (the earlier of which will be the “Time of Expiry” for the purposes of Article 6 in respect of the Initial Debentures), to convert the whole or, in the case of a Debenture of a denomination in excess of $1,000, any part which is $1,000 or an integral multiple thereof, of the principal amount of such Debenture into Freely Tradeable Shares at the Conversion Price for the Initial Debentures in effect on the Date of Conversion.

The Conversion Price for the Initial Debentures in effect on the date hereof for each Share to be issued upon the conversion of Initial Debentures shall be equal to $15.00 such that approximately 66.6667 Shares shall be issued for each $1,000 principal amount of Initial Debentures so converted. Holders converting their Initial Debentures shall be entitled to receive, in addition to the applicable number of Freely Tradeable Shares, accrued and unpaid interest in respect of such Debentures for the period from and including the last Interest Payment Date on which interest was paid in full in accordance with this Indenture to but excluding the Date of Conversion. The Conversion Price applicable to, and the Shares, securities or other property receivable on the conversion of the Initial Debentures, is subject to adjustment pursuant to the provisions of Section 6.4.

On redemption or on maturity of the Initial Debentures, the Corporation may, at its option and subject to the provisions of Section 4.6, Section 4.10, and Section 7.8, as applicable, and subject to regulatory approval, if required, elect to satisfy its obligation to pay the principal amount of the Initial Debentures, in whole or in part, by issuing and delivering Freely Tradeable Shares to the holders of Initial Debentures. If the Corporation elects to exercise such option, it shall deliver a Redemption Notice or a maturity notice (the “Maturity Notice”), as the case may be, to the holders of the Initial Debentures in the form of Schedule B or Schedule C, as applicable.

The Initial Debentures shall be issued as one or more Global Debentures 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. Each Initial Debenture issued as a Global Debenture and the certificate of the Trustee endorsed thereon shall be issued in substantially the form set out in Schedule A, with such insertions, omissions, substitutions or other variations as shall be required or permitted by this Indenture and may have imprinted or otherwise reproduced thereon such legend or legends or endorsements, not inconsistent with the provisions of this Indenture, as may be required to comply with any law or with any rules or regulations pursuant thereto or with any rules or regulations of any securities exchange or securities regulatory authority or to conform with general usage, all as may be determined by the representative of the Corporation executing such Global Debentures in accordance with Section 2.7, as conclusively evidenced by its execution of a Global Debenture. Each Initial Debenture shall additionally bear such distinguishing letters and numbers as the Trustee shall approve. Notwithstanding the foregoing, an Initial Debenture may be in such other form or forms as may, from time to time, be approved by a resolution of the directors or as specified in an Officer’s Certificate. The Initial Debentures may be engraved, lithographed, printed, mimeographed or typewritten or partly in one form and partly in another.

The Initial Debentures shall be represented by one or more Global Debentures. Beneficial interests in Global Debentures will be represented through book-entry accounts of participants in the Depository (“Participants”) on behalf of the applicable Beneficial Debentureholders in accordance with the rules and procedures of the Depository. Any circumstances other than or in addition to those set forth in Section 3.2 in which any Global Debentures may be exchanged for Debentures in registered form that are not Global Debentures, or transferred to and registered in the name of a person other than the Depository for such Global Debentures or a nominee thereof, shall be determined by the Corporation at the time of issue.

Neither the Corporation nor the Trustee shall have any liability for:

the records maintained by the Depository or any other Person relating to beneficial interests in Global Debentures or the book-entry accounts maintained by the Depository;

maintaining, supervising or reviewing any records relating to such beneficial ownership interests or payments made by any Person (other than the Corporation) in respect thereof;

any advice or representation made or given by the Depository or made or given herein with respect to the rules and regulations of the Depository; or,

any action to be taken by the Depository at the direction of its Participants. Except as provided herein Beneficial Debentureholders shall not be entitled to have Debentures registered in their names, shall not receive or be entitled to receive definitive certificates for the Debentures and shall not be considered owners or holders thereof under this Indenture.

Upon and subject to the provisions and conditions of Article 10, the Corporation may elect, from time to time, to issue and solicit bids to sell sufficient Freely Tradeable Shares in order to raise funds to satisfy its Interest Obligation, in whole or in part, on the Initial Debentures on any Interest Payment Date.

Upon the occurrence of a Change of Control, and subject to the provisions and conditions of this Section 2.4(j), holders of Initial Debentures have a right to (i) require the Corporation to purchase their Initial Debentures or (ii) convert their Initial Debentures. The terms and conditions of such rights are set forth below:

Upon the occurrence of a Change of Control, each holder of Initial Debentures shall have the right (i) to require the Corporation to purchase (the “Put Right”), on the date (the “Put Date”) which is 30 days following the date upon which the Trustee delivers a Change of Control Notice (as defined below) to the holders of Initial Debentures, all or any part of such holder’s Initial Debentures in accordance with the requirements of Applicable Securities Legislation at a price equal to 100% of the principal amount thereof plus accrued and unpaid interest on such Initial Debentures up to, but excluding, the Put Date (less any tax required to be withheld) (collectively, the “Total Put Price”), which will be payable in cash or (ii) to convert (the “Change of Control Conversion Right”) all or any part of such holder’s Initial Debentures at the Change of Control Conversion Price (as defined below).

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

The Corporation will, as soon as practicable after the occurrence of a Change of Control and in any event no later than five Business Days thereafter, give written notice to the Trustee of the Change of Control. Such written notice of the Corporation shall be in the form of Schedule D and shall state the Total Put Price and the Change of Control Conversion Price. The Trustee will, as soon as practicable thereafter, and in any event no later than two Business Days after receiving notice from the Corporation of the occurrence of a Change of Control, provide such written notice to the holders of Initial Debentures of the Change of Control (the “Change of Control Notice”).

To exercise the Put Right or the Change of Control Conversion Right, the holder of Initial Debentures must deliver to the Trustee, not less than five Business Days prior to the Put Date, written notice of the holder’s exercise of such right in the form attached as Schedule E together with (a) the Initial Debentures with respect to which the right is being exercised, duly endorsed for transfer, or (b) if the Initial Debentures have been issued as Global Debentures, a duly endorsed form of transfer.

If 90% or more in aggregate principal amount of Initial Debentures outstanding on the date the Corporation provides notice of a Change of Control to the Trustee have been tendered for purchase pursuant to the Put Right or converted pursuant to the Change of Control Conversion Right in accordance with Section 2.4(j)(iii), the Corporation has the right (but not the obligation) upon written notice provided to the Trustee prior to the Put Date, to redeem all the remaining outstanding Initial Debentures on the Put Date at the Total Put Price (the “90% Redemption Right”).

Upon receipt of written notice that the Corporation shall exercise the 90% Redemption Right and acquire the remaining Initial Debentures, the Trustee shall as soon as reasonably possible provide written notice to all holders of Initial Debentures that did not previously exercise the Put Right that:

The Corporation has exercised the 90% Redemption Right and will purchase all outstanding Initial Debentures on the Put Date at the Total Put Price, including a calculation of such holder’s Total Put Price;

Such holders must transfer their Initial Debentures to the Trustee on the same terms as those holders that exercised the Put Right and must send their respective Initial Debentures, duly endorsed for transfer, or their duly endorsed form of transfer, as applicable, to the Trustee within 10 days after sending of such notice; and

Subject to Section 2.4(j)(xvi), the rights of such holders under the terms of the Initial Debentures cease as of the Put Date provided the Corporation has paid the Total Put Price to, or to the order of, the Trustee, and thereafter the Initial Debentures shall not be considered to be outstanding and the holder shall not have any right except to receive the Total Put Price upon surrender and delivery of such holders’ Initial Debentures in accordance with the Indenture.

The Corporation shall, on or before 11:00 a.m., (Toronto time) on the Business Day immediately prior to the Put Date, deposit with the Trustee or any paying agent to the order of the Trustee by an electronic funds transfer such sums of money as may be sufficient to pay the Total Put Price of the Initial Debentures to be purchased or redeemed by the Corporation on the Put Date plus the amount payable in lieu of any fractional Shares issuable upon the conversion of the Initial Debentures converted on the Put Date and on or before the Put Date certificates or other evidence of the Shares issuable upon the conversion of the Initial Debentures converted on the Put Date. The Trustee shall disburse such payments and deliver such certificates or other evidence of the Shares only upon receiving the required funds and certificates or other evidence of the Shares. To the extent requested by the Trustee, the Corporation shall also deposit with the Trustee a sum of money sufficient to pay any charges or expenses which may be incurred by the Trustee in connection with such purchase and/or redemption and/or conversion, as the case may be. Every such deposit shall be irrevocable. From the sums so deposited, the Trustee shall pay or cause to be paid to the holders of such Initial Debentures, the Total Put Price, and interest, if any, to which they are entitled on the Corporation’s purchase or redemption, and/or the amount payable in lieu of any fractional Shares and certificates or other evidence of the Shares issuable upon the conversion, of the Initial Debentures. The Trustee shall not be responsible for calculating the amount of monies or Shares owing but shall be entitled to rely on the Written Direction of the Corporation specifying the payments to be made and/or Shares to be issued.

In the event that one or more of such Initial Debentures being purchased or converted in accordance with this Section 2.4(j) becomes subject to purchase or conversion in part only, upon surrender of such Initial Debentures for payment of the Total Put Price or delivery of the Shares issuable upon conversion of such Initial Debentures plus payment of an amount in cash in lieu of any fractional Shares, certificates or other evidence of one or more new Initial Debentures for the portion of the principal amount of the Initial Debentures not purchased shall be delivered to the holder thereof or upon the holder’s order without charge.

Initial Debentures for which holders have exercised the Put Right and Initial Debentures which the Corporation has elected to redeem in accordance with this Section 2.4(j) shall become due and payable on the Put 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 such Put Date, if the money necessary to purchase or redeem the Initial Debentures shall have been deposited as provided in this Section 2.4(j) 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 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.

Initial Debentures for which holders have exercised the Change of Control Conversion Right in accordance with this Section 2.4(j) shall be converted on the Put Date, and from and after such Put Date, if the Freely Tradeable Shares and payment in lieu of any fractional Shares, if applicable, issuable and payable upon such conversion of the Initial Debentures shall have been deposited as provided in this Section 2.4(j) 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 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.

In case the holder of any Initial Debenture to be converted, purchased or redeemed in accordance with this Section 2.4(j) shall fail on or before the Put Date to so surrender such holder’s Initial Debenture or duly endorsed form of transfer or shall not within such time accept payment of the moneys payable, or take delivery of certificates, if any, representing any Shares issuable in respect thereof, or give such receipt therefor, if any, as the Trustee may require, such moneys may be set aside in trust, or such certificates may be held in trust without interest, either in the deposit department of the Trustee or in a chartered bank, and such setting aside shall for all purposes be deemed a payment to the Debentureholder of the sum so set aside and, to that extent, the Initial Debenture shall thereafter not be considered as outstanding hereunder and the Debentureholder shall have no other right except to receive payment out of the moneys so paid and deposited, or to take delivery of the certificates so deposited, upon surrender and delivery up of such holder’s Initial Debenture, of the money set aside plus accrued and unpaid interest to the Put Date and subsequent distribution and accretions, on such Shares, if any, as the case may be. Subject to applicable law, in the event that any money, or certificates, 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 ten years from the Put Date, then such moneys, or certificates, together with any accumulated interest 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 and, subject to applicable law, thereafter the holder of an Initial Debenture in respect of which such money was so repaid to the Corporation shall have no rights except to obtain the payment of the money or certificates due from the Corporation, subject to any limitation period provided by the laws of Ontario. Notwithstanding the foregoing, the Trustee will pay any remaining funds deposited hereunder prior to the expiry of ten years after the Put 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 ten years after the Put Date, the Corporation shall reimburse the Trustee for any amounts required to be paid by the Trustee to a holder of an Initial Debenture in respect thereof after the date of such payment of the remaining funds to the Corporation but prior to ten years after the Put Date and such letter of credit shall be reduced to the extent of the amount of such disbursement. If the Corporation fails to so reimburse the Trustee, the Trustee may draw on the letter of credit.

Subject to the provisions above related to Initial Debentures converted, purchased or 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.

The Corporation will publicly announce the results of the purchases made pursuant to Section 2.4(j) as soon as practicable after the Put Date.

The Corporation will comply with all Applicable Securities Legislation in the event that the Corporation is required to repurchase Initial Debentures pursuant to Section 2.4(j).

No fractional Shares shall be issued upon conversion of Initial Debentures but in lieu thereof the Corporation shall satisfy fractional interests by a cash payment. In the event the Corporation is required to deliver Freely Tradeable Shares, the conditions of paragraph (c) of Section 4.10 shall apply, mutatis mutandis to such obligation. Holders of Debentures who elect to exercise the Change of Control Conversion Right shall be entitled to receive and shall accept, in lieu of the number of Shares such holders would have been entitled to receive, such number of Shares or other securities or assets that such holders would have been entitled to if such holders had been the registered holders of the applicable number of Shares on the Effective Date.

Upon conversion of the Initial Debentures, if the principal amount (or any portion thereof) to which a holder is entitled is subject to withholding taxes pursuant to Section 7.8, the Trustee, on the Written Direction of the Corporation but for the account of the holder, shall provide reasonable assistance to effect the sale, through the investment banks, brokers or dealers selected by the Corporation, out of the Freely Tradeable Shares issued by the Corporation for this purpose, such number of Freely Tradeable Shares that 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.

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

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

a Written Direction of the Corporation requesting certification, if applicable, and delivery of such Additional Debentures and setting forth delivery instructions;

an opinion of Counsel that the issue and sale of the Additional Debentures do not and will not result in a breach (whether after notice or lapse of time or both) of:

any of the terms, conditions or provisions of the Corporation’s articles or bylaws, or

any statute, rule or regulation of the Province of Ontario or the federal laws of Canada applicable therein and which are applicable to the Corporation,

an Officer’s Certificate 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 Officer’s Certificate and that no Event of Default exists or will exist upon such certification and delivery.

The Corporation may specify that the Debentures of a series are to be issued in whole or in part as one or more Global Debentures, subject to Section 3.4(f). Global Debentures shall be registered in the name of a Depository, or its nominee, designated by the Corporation in the Written Direction of the Corporation delivered to the Trustee at the time of issue of such Debenture. In the event Debentures are issued as Global Debentures, the Corporation shall execute and the Trustee shall certify and deliver one or more Global Debentures that shall:

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

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

bear a legend substantially to the following effect (or as otherwise requested by the Depository):

“This Debenture is a Global Debenture within the meaning of the Indenture hereinafter referred to and is registered in the name of a Depository or a nominee thereof. This Debenture may not be transferred to or exchanged for Debentures registered in the name of any person other than the Depository or a nominee thereof and no such transfer may be registered except in the limited circumstances described in the Indenture. Every Debenture authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, this Debenture shall be a Global Debenture subject to the foregoing, except in such limited circumstances described in the Indenture.”

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

Subject to Section 2.4(b) 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 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 the outstanding Debentures of that series, whichever shall be the later, to but excluding the next Interest Payment Date.

Unless otherwise specifically provided in the terms of the Debentures of any series, interest for any period of less than six months shall be computed on the basis of a year of 365 days. Subject to Section 2.4(b) in respect of the method for calculating the amount of interest to be paid on the Initial Debentures on the first Interest Payment Date in respect thereof, with respect to any series of Debentures, whenever interest is computed on a 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.

As interest becomes due on each Debenture (except at maturity 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 electronic transfer of funds (if agreed by the Debentureholder and authorized and directed by a Written Direction of the Corporation), by cheque dated the Interest Payment Date or by such other means as may be agreed to by the Trustee, payment of such interest (less any tax required to be withheld therefrom pursuant to Section 7.8) 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 15^th day of the month in which the applicable Interest Payment Date occurs (or, if such 15^th day is not a Business Day, on the first Business Day following such 15^th day) such dates being June 15 and December 15 in respect of the Initial Debentures (each a “Record Date”), unless such holder otherwise directs. If payment is made by cheque, such cheque shall be dated the Interest Payment Date and mailed on or before the 5^th Business Day preceding the applicable Interest Payment Date to the address of the holder appearing in the register maintained by the Trustee at the close of business on the Record Date. If payment is made by other means (such as electronic transfer of funds), such payment shall be made in a manner whereby the holder receives credit for such payment on the date such interest on such Debenture becomes due. The mailing of such cheque or the making of such payment by other means shall, to the extent of the sum represented thereby, plus the amount of any tax withheld as aforesaid, satisfy and discharge all liability for interest then due on such Debenture, unless in the case of payment by cheque, such cheque be 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 the same amount upon being furnished with such evidence of nonreceipt 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 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. If payment is made by the Trustee, by 11:00 a.m. (Toronto time) on the Business Day immediately prior to each Interest Payment Date or by the date of mailing the cheques for the interest due on an Interest Payment Date, whichever is earlier, the Corporation shall deliver sufficient funds to the Trustee by electronic transfer or certified cheque or make such other arrangements for the provisions of funds as may be agreeable between the Trustee and the Corporation in order to effect such interest payment hereunder.

Notwithstanding Section 2.14(a), if a series of Debentures is represented by a Global Debenture, then all payments of interest on the Global Debenture shall be made by electronic funds transfer by 11:00 a.m. (Toronto time) on such Interest Payment Date to the Depository or its nominee for subsequent payment to holders of interests in that Global Debenture, unless the Corporation and the Depository otherwise agree. None of the Corporation, the Trustee or any agent of the Trustee for any Debenture issued as a Global Debenture will be liable or responsible to any person for any aspect of the records related to or payments made on account of beneficial interests in any Global Debenture or for maintaining, reviewing, or supervising any records relating to such beneficial interests.

The Trustee shall disburse such interest payments only upon receiving the required funds from the Corporation.

Not less than 24 hours prior to the Interest Payment Date, the Corporation shall forward to the Trustee a Written Direction of the Corporation specifying payments to be made. The Trustee shall not be responsible for calculating the amount of interest owing and shall be entitled to rely absolutely on the Written Direction of the Corporation specifying the payments to be made.

Notwithstanding the foregoing, (i) all payments in excess of $25 million to a holder other than the Depository (or such other amount as determined from time to time by the Canadian Payments Association or any successor thereto) shall be made by the use of the LVTS; and (ii) in the event that payment must be made to the Depository, such payment shall be made by LVTS and the Corporation shall remit payment to the Trustee by LVTS. The Trustee shall have no obligation to disburse funds pursuant to this Section 2.14 unless it has received written confirmation satisfactory to it that the funds have been deposited with it in sufficient amount to pay in full all amounts due and payable with respect to such Interest Payment Date. The Trustee shall, if any funds are received by it in the form of uncertified cheques, be entitled to delay the time for release of such funds until such uncertified cheques shall be determined to have cleared the financial institution upon which the same are drawn.

With respect to each series of Debentures issuable as Fully Registered Debentures, the Trustee shall cause to be kept by and at the Designated Office, 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 unless a new Debenture shall be issued upon such transfer.

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 execution satisfactory to the Trustee 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 may prescribe, nor unless the name of the transferee shall have been noted on the Debenture by the Trustee.

With respect to each series of Debentures issuable in whole or in part as one or more Global Debentures, the Corporation shall cause to be kept by and at the Designated Office, a register in which shall be entered the name and address of the holder of each such Global Debenture (being the Depository, or its nominee, for such Global Debenture) as holder thereof and particulars of the Global Debenture held by it, and of all transfers thereof. If any Debentures of such series are at any time not Global Debentures, the provisions of Section 3.1 shall govern with respect to registrations and transfers of such Debentures.

Notwithstanding any other provision of this Indenture, a Global Debenture may not be transferred by the registered holder thereof except in the following circumstances or as otherwise specified in the resolution of the directors of the Corporation, Officer’s Certificate or supplemental indenture relating to a particular series of Additional Debentures:

the Global Debenture may be transferred by a Depository to a nominee of such Depository or by a nominee of a Depository to such Depository or to another nominee of such Depository or by a Depository or its nominee to a successor Depository or its nominee;

the Global Debenture may be transferred at any time after the Depository for such Global Debenture (i) has notified the Corporation that it is unwilling or unable to continue as Depository for such Global Debenture or (ii) ceases to be eligible to be a Depository under Section 2.6(b) provided that at the time of such transfer the Corporation and the Trustee have not appointed a successor Depository for such Global Debenture;

the Global Debenture may be transferred at any time after the Corporation has determined, in its sole discretion, to terminate the book-entry only registration system in respect of such Global Debenture and has communicated such determination to the Trustee in writing; and

the Global Debenture may be transferred at any time after the Trustee has determined that an Event of Default has occurred and is continuing with respect to the Debentures of the series issued as a Global Debenture, provided that at the time of such transfer the Trustee has not waived the Event of Default pursuant to Section 8.3.

Each Global Debenture shall bear the following legend (the “Depository Legend”):

“Unless this certificate is presented by an authorized representative of CDS Clearing and Depository Services Inc. (“CDS”) to ▇▇▇▇▇▇▇▇ Lake Gold Inc. or its agent for registration of transfer, exchange or payment, and any certificate issued in respect thereof is registered in the name of CDS & CO, or in such other name as is requested by an authorized representative of CDS (and any payment is made to CDS & CO or to such other entity as is requested by an authorized representative of CDS), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL since the registered holder hereof, CDS & CO, has a property interest in the securities represented by this certificate herein and it is a violation of its rights for another person to hold, transfer or deal with this certificate.”

Global Debentures shall be subject to the following:

the Trustee may deal with the Depository as the authorized representative of the applicable Beneficial Debentureholders;

the rights of the applicable Beneficial Debentureholders shall be exercised only through the Depository and the rights of such Beneficial Debentureholders shall be limited to those established by applicable law and agreements between the Depository and the Participants and between such Participants and such Beneficial Debentureholders, and must be exercised through a Participant in accordance with the rules and procedures of the Depository;

the Depository will make book-entry transfers among the direct Participants of the Depository and will receive and transmit distributions of principal, premium (if any), and interest on the Debentures to such direct Participants; and

the direct Participants of the Depository shall have no rights under this Indenture or under or with respect to any of the Debentures represented by a Global Debenture held on their behalf by the Depository, and the Depository may be treated by the Trustee and its agents, employees, officers and directors as the absolute owner of the Debentures represented by such Global Debentures for all purposes whatsoever.

Notwithstanding anything to the contrary set out herein, all physical Global Debentures issued to the Depository may be surrendered to the Trustee for an electronic position on the register of Debentureholders to be maintained by the Trustee. All Global Debentures maintained in such electronic position will be valid and binding obligations of the Corporation, entitling the registered holders thereof to the same benefits as those registered holders who hold Global Debentures in physical form. This Indenture and the provisions contained herein will apply mutatis mutandis to such Debentures held in such electronic position.

Notwithstanding anything herein contained to the contrary, any Debentures issued to U.S. Purchasers (the “Restricted Debentures”) shall be issued in accordance with the provisions of Section 3.4.

If, at any time, a holder of a Restricted Debenture bearing the U. S. Securities Act Legend wishes to transfer its interest therein to a Person required or permitted to take delivery thereof in the form of an interest in a Debenture that does not contain the U. S. Securities Act Legend, including the Global Debenture issued in accordance with the provisions of Section 3.2 (an “Unrestricted Debenture”), the Trustee will reduce the outstanding principal amount of such Restricted Debenture by such amount and increase the outstanding principal amount of the corresponding Unrestricted Debenture to which such holder’s interest is transferred by such transferred amount.

Any Debentures issued to U.S. Purchasers pursuant to Section 3.3(a) shall be issued as Fully Registered Debentures in authorized denominations, shall have the same benefits and be subject to the same terms and conditions as the Unrestricted Debentures, shall be registered in the names and denominations as the Corporation shall direct and shall be delivered as directed by the persons in whose names such Restricted Debentures are to be registered. The Restricted Debentures shall be in substantially the form of the Unrestricted Debentures mutatis mutandis, except as provided in Section 3.4(b) and except that they shall not include the Depository Legend.

Each Restricted Debenture, as well as all certificates or other global notes issued in exchange for or in substitution of the foregoing securities, will bear the U.S. Securities Act Legend; provided that, (i) if any interest in a Restricted Debenture is being sold outside the United States in accordance with Rule 904 of Regulation S at a time when the Corporation is a “foreign issuer” as defined in Rule 902(e) of Regulation S the legend may be removed by providing a duly completed and signed declaration to the Trustee, as registrar and transfer agent, to the effect set forth in Schedule G hereto (or in such other form as the Corporation may from time to time prescribe) and, if required by the Trustee, an opinion of counsel of recognized standing satisfactory to the Trustee, acting reasonably, that such legend is no longer required under the applicable requirements of the U. S. Securities Act or U.S. state securities laws, and provided further, that, (ii) if any interest in a Restricted Debenture is (a) being sold in the United States or (b) eligible for resale, in accordance with Rule 144 under the U. S. Securities Act, such legend may be removed by delivery to the Trustee of an opinion of U.S. counsel of recognized standing, satisfactory to the Corporation, acting reasonably, that such legend is no longer required under applicable requirements of the U.S. Securities Act or U.S. state securities laws.

If a Restricted Debenture or an interest therein tendered for transfer bears the U.S. Securities Act Legend and the transferee is a U.S. Purchaser in the United States, except as provided in Section 3.4(b), the Restricted Debenture or interest therein issued to such transferee shall also bear the U.S. Securities Act Legend.

Debentures may not be converted into Shares in the United States unless an exemption is available from registration requirements of the U. S. Securities Act, including Section 3(a)(9) of the U.S. Securities Act, and applicable state securities laws.

Any Shares into which the Restricted Debentures are convertible shall also bear the U.S. Securities Act Legend unless the provisions of Section 3.4(b), apply thereto mutatis mutandis.

The Corporation, in issuing Restricted Debentures in the form of one or more Global Debentures shall use a designated “CUSIP” number and promptly notify the Trustee of the “CUSIP” number and designation of the Restricted Debentures. The Trustee shall use the “CUSIP” number to identify such Restricted Debentures in notices as a convenience to Debentureholders and the Depository; provided that any such notice may state that no representation is made as to the correctness of such number either as printed on the Debentures or as contained in any notice and that reliance may be placed only on the other identification number(s) printed on the Debentures, and any such notice shall not be affected by any defect in or omission of such number. The Corporation will promptly notify the Trustee of any change in the “CUSIP” number. Notwithstanding the foregoing, no Restricted Debentures will be issued in the form of Global Debentures, except to Qualified Institutional Buyers.

The Trustee shall maintain a list of all registered holders of Restricted Debentures or interests therein or Shares into which they are converted bearing the U. S. Securities Act Legend.

Subject to Section 3.9, Debentures in any authorized form or denomination, other than Global Debentures, may be exchanged for Debentures in any other authorized form or denomination, of the same series and date of maturity, bearing the same interest rate and of the same aggregate principal amount as the Debentures so exchanged.

In respect of exchanges of Debentures permitted by Section 3.8(a), Debentures of any series may be exchanged only at the Designated Office. Any Debentures tendered for exchange shall be surrendered to the Trustee. The Corporation shall execute and the Trustee shall certify all Debentures necessary to carry out exchanges as aforesaid. All Debentures surrendered for exchange shall be cancelled.

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.

accept conversions of any Fully Registered Debentures during the period from the close of business on the Record Date preceding the Interest Payment Date to and including such Interest Payment Date;

make transfers or exchanges of any Debentures during the period from the date of any selection by the Trustee of any Debentures to be redeemed or during the preceding 15 days or thereafter until the close of business on the date upon which a Redemption Notice is given in respect of such Debentures; or

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

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;

for any exchange of any interim or temporary Debenture or interim certificate that has been issued under Section 2.9 for a definitive Debenture;

for any exchange of a Global Debenture as contemplated in Section 3.2; or

for any exchange of any Debenture resulting from a partial redemption under Section 4.2.

Unless otherwise required by law, the person in whose name any registered Debenture is registered shall for all the 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, in the case of a Fully Registered Debenture, interest thereon shall be made to such registered holder.

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 setoff 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 Corporation and/or the Trustee for the same and neither the Corporation nor the Trustee shall be bound to inquire into the title of any such registered holder.

Where Debentures are registered in more than one name, the principal, premium, if any, and interest (in the case of Fully Registered Debentures) 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 and to the Corporation.

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 to the Corporation.

The Trustee may assume for the purposes of this Indenture that any address of the holder appearing in the register maintained by the Trustee is the holder’s actual address.

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);

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

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

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.

Subject to the other provisions of this Section 4.6, the Corporation may, at its option, elect to satisfy its obligation to pay the Redemption Price in whole or in part by issuing and delivering to holders on the Redemption Date that number of Freely Tradeable Shares obtained by dividing the aggregate principal amount of Debentures being redeemed by 95% of the Current Market Price of the Shares on the Redemption Date (the “Share Redemption Right”).

The Corporation shall exercise the Share Redemption Right by so specifying in the Redemption Notice set forth in Schedule D, 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 Redemption Date. The Redemption Notice shall also specify the aggregate principal amount of Debentures in respect of which it is exercising the Share Redemption Right.

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

the Shares to be issued on exercise of the Share Redemption Right being Freely Tradeable;

the conditional listing of such additional Shares on each stock exchange on which the Shares are then listed subject only to customary conditions of listing;

the Corporation being a reporting issuer (or its equivalent) not in default under Applicable Securities Legislation where the distribution of such Shares occurs;

no Event of Default shall have occurred and be continuing;

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

the receipt by the Trustee of an opinion of Counsel dated the Redemption Date to the effect that such 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 nonassessable, that condition (i) above has been satisfied, relying exclusively on correspondence from the relevant stock exchange, that condition (ii) above has been satisfied, and, relying exclusively on reporting issuer lists published by the relevant securities authorities, that condition (iii) above is satisfied, except that the opinion in respect of condition (iii) need not be expressed with respect to those provinces and territories where reporting issuer lists are not published.

In the event that the Corporation duly exercises its Share Redemption Right, the Corporation shall on or before 11:00 a.m. (Toronto time) on the Redemption Date make the delivery to the Trustee for delivery to and on account of the holders, 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, of certificates or other evidence representing the Freely Tradeable Shares and a cheque representing accrued and unpaid interest to which such holders are entitled (less any tax required to be withheld pursuant to Section 7.8, if any). Such Freely Tradeable Shares shall initially be registered in the name of the Trustee until such time as the holder of such Debentures has surrendered its Debentures or duly endorsed form of transfer to the Trustee.

No fractional Freely Tradeable Shares shall be delivered upon the exercise of the 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 Shares on the Redemption Date (less any tax required to be deducted, if any). Upon request by the Trustee, the Corporation shall provide, in writing to the Trustee, the price to be paid in respect of such fractional Shares.

A holder shall be treated as the shareholder of record of the Freely Tradeable Shares issued on due exercise by the Corporation of its 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 dividends or distributions in kind) thereon and arising thereafter, and in the event that the Trustee receives the same, it shall hold the same in trust for the benefit of such holder.

The Corporation shall issue to Debentureholders to whom Freely Tradeable Shares will be issued pursuant to exercise of the Share Redemption Right, such number of Freely Tradeable Shares as shall be issuable in such event. All Freely Tradeable Shares which shall be so issuable shall be duly and validly issued as fully paid and nonassessable.

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 or territory 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 Shares to holders upon exercise of the Share Redemption Right pursuant to the terms of the Debentures and of this Indenture.

If the Corporation elects to satisfy its obligation to pay the Redemption Price by issuing Freely Tradeable 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 pursuant to Section 7.8, the Trustee, on the Written Direction of the Corporation but for the account of the holder, shall provide reasonable assistance to effect the sale, through the investment banks, brokers or dealers selected by the Corporation, out of the Freely Tradeable Shares issued by the Corporation for this purpose, such number of Freely Tradeable Shares that 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. In the event the Trustee sells such Freely Tradeable Shares pursuant to this Section 4.6(i), the procedures set forth in Article 10 of this Corporation Indenture shall apply mutatis mutandis to such sale. The Trustee shall not be responsible for the purchase price or the timing of the sale of such Shares.

In the event the Corporation exercises its Share Redemption Right, the Corporation shall reserve and keep available out of its authorized Shares such number of Shares as shall be issuable in such event (if the number thereof becomes limited) solely for the purpose of issue and delivery upon the exercise of the Share Redemption Right as provided herein, and shall issue such Shares to Debentureholders to whom the Shares will be issued pursuant to exercise of the Share Redemption Right.

Interest accrued and unpaid on the Debentures on the Redemption Date will be paid to Debentureholders in the manner contemplated in Section 2.14.

Unless otherwise specifically provided with respect to a particular series of Debentures, the Corporation may at any time and from time to time, purchase Debentures in the market (which shall include purchase 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, subject to compliance with Applicable Securities Legislation regarding issuer bids. If an Event of Default has occurred and is continuing, the Corporation may purchase all or any of the Debentures as aforesaid.

All Debentures so purchased 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, in such manner (which may include selection by lot, selection on a pro rata basis, random selection by computer or any other method) as 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 of which a part only is purchased, upon surrender of such Debenture for payment, shall be entitled to receive, without expense to such holder, one or more new Debentures for the unpurchased part so surrendered, and the Trustee shall certify and deliver such new Debenture or Debentures upon receipt of the Debenture so surrendered or, with respect to a Global Debenture, the Depository shall make notations on the Global Debenture of the principal amount thereof so purchased or.

Subject to the other provisions of this Section 4.10 and subject to any required regulatory approval, the Corporation may, at its option, elect to satisfy its obligation to repay the principal amount of the Debentures outstanding, in whole or in part, by issuing and delivering to holders on the maturity of such Debentures (the “Maturity Date”) that number of Freely Tradeable Shares obtained by dividing the aggregate principal amount of the Debentures by 95% of the Current Market Price of the Shares on the Maturity Date (the “Share Repayment Right”).

The Corporation shall exercise the Share Repayment Right by so specifying in the Maturity Notice set forth in Schedule C, 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. The Maturity Notice shall also specify the aggregate principal amount of Debentures in respect of which it is exercising the Share Repayment Right.

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

the Shares to be issued on exercise of the Share Repayment Right being Freely Tradeable;

the conditional listing of such additional Shares on each stock exchange on which the Shares are then listed subject only to customary conditions of listing;

the Corporation being a reporting issuer (or its equivalent) not in default under Applicable Securities Legislation where the distribution of such Shares occurs;

no Event of Default shall have occurred and be continuing;

the receipt by the Trustee of an Officer’s Certificate stating that conditions (i), (ii), (iii) and (iv) above have been satisfied and setting forth the number of Shares to be delivered for each $1,000 principal amount of Debentures and the Current Market Price of the Shares on the Maturity Date; and

the receipt by the Trustee of an opinion of Counsel dated the Maturity Date to the effect that such Shares have been duly authorized and, when issued and delivered pursuant to the terms of this Indenture in payment, in whole or in part, of the principal amount of the Debentures outstanding will be validly issued as fully paid and non assessable, that condition (i) above has been satisfied, relying exclusively on correspondence from the relevant stock exchange, that condition (ii) above has been satisfied, and, relying exclusively on reporting issuer lists published by the relevant securities authorities, that condition (iii) above is satisfied, except that the opinion in respect of condition (iii) need not be expressed with respect to those provinces and territories where lists are not published.

In the event that the Corporation duly exercises its Share Repayment Right, the Corporation shall on or before 11:00 a.m. (Toronto time) on the Maturity Date make the delivery to the Trustee for delivery to and on account of the holders, 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, of certificates or other evidence representing the Freely Tradeable Shares and a cheque representing accrued and unpaid interest to which such holders are entitled (less any tax required to be withheld, if any). Such Freely Tradeable Shares shall initially be registered in the name of the Trustee until such time as the holder of such Debentures has surrendered its Debentures or duly endorsed form of transfer to the Trustee.

(e)

No fractional Freely Tradeable Shares shall be delivered upon the exercise of the 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 Shares on the Maturity Date (less any tax required to be withheld pursuant to Section 7.8, if any). Upon request by the Trustee, the Corporation shall provide, in writing to the Trustee, the price to be paid in respect of such fractional Shares.

(f)

A holder shall be treated as the shareholder of record of the Freely Tradeable Shares issued on due exercise by the Corporation of its 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 dividends or distributions in kind) thereon and arising thereafter, and in the event that the Trustee receives the same, it shall hold the same in trust for the benefit of such holder.

(g)

The Corporation shall issue to Debentureholders to whom Freely Tradeable Shares will be issued pursuant to exercise of the Share Repayment Right, such number of Freely Tradeable Shares as shall be issuable in such event. All Freely Tradeable Shares which shall be so issuable shall be duly and validly issued as fully paid and nonassessable.

(h)

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 or territory 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 Shares to holders upon exercise of the Share Repayment Right pursuant to the terms of the Debentures and of this Indenture.

(i)

If the Corporation elects to satisfy its obligation, in whole or in part, to pay the principal amount on maturity by issuing Freely Tradeable Shares in accordance with this Section 4.10, and if the principal amount (or any portion thereof) to which a holder is entitled is subject to withholding taxes pursuant to Section 7.8, the Trustee, on the Written Direction of the Corporation but for the account of the holder, shall provide reasonable assistance to effect the sale, through the investment banks, brokers or dealers selected by the Corporation, out of the Freely Tradeable Shares issued by the Corporation for this purpose, such number of Freely Tradeable Shares that 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. In the event the Trustee sells such Freely Tradeable Shares pursuant to this Section 4.10(i), the procedures set forth in Article 10 of this Indenture shall apply mutatis mutandis to such sale. The Trustee shall not be responsible for the purchase price or the timing of the sale of such Shares.

In the event the Corporation exercises its Share Repayment Right, the Corporation shall reserve and keep available out of its authorized Shares such number of Shares as shall be issuable in such event (if the number thereof becomes limited) solely for the purpose of issue and delivery upon the exercise of the Share Repayment Right as provided herein, and shall issue such Shares to Debentureholders to whom the Shares will be issued pursuant to exercise of the Share Repayment Right.

Interest accrued and unpaid on the Debentures on the Maturity Date will be paid to Debentureholders in the manner contemplated in Section 2.14.

all Senior Indebtedness shall first be paid in full, or provision made for such payment, before any payment is made on account of the principal of or interest on the indebtedness evidenced by the Debentures; and

any payment or distribution of assets of the Corporation, whether in cash, property or securities, to which the holders of the Debentures or the Trustee on behalf of such holders would be entitled except for the provisions of this Article 5, shall be paid or delivered by the trustee in bankruptcy, receiver, assignee for the benefit of creditors, or other liquidating agent making such payment or distribution, directly to the holders of Senior Indebtedness or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any of such Senior Indebtedness may have been issued, to the extent necessary to pay all Senior Indebtedness in full after giving effect to any concurrent payment or distribution, or provision therefor, to the holders of such Senior Indebtedness.

Subject to the payment in full of all Senior Indebtedness, to the extent that any payment or distribution of assets of the Corporation otherwise payable to the Trustee on account of the Debentureholders is made on account of the Senior Indebtedness pursuant to the application of Section 5.2, the Debentureholders shall be subrogated to the rights of the holders of Senior Indebtedness to receive payments and distributions of assets of the Corporation made in respect of or on account of Senior Indebtedness, until the principal of, premium, if any, and interest on the Debentures shall be paid in full. No payment or distribution of assets of the Corporation to the Debentureholders which would be payable or distributable to the holders of Senior Indebtedness pursuant to this Article 5 shall, as between the Corporation, its creditors (other than the holders of Senior Indebtedness) and the Debentureholders, be deemed to be a payment of the Corporation to or on account of the Debentureholders, it being understood that the provisions of this Article 5 are, and are intended, solely for the purpose of defining the relative rights of the Debentureholders, on the one hand, and the holders of the Senior Indebtedness, on the other hand.

(b)

The Debentures shall be subordinated to claims of creditors of the Corporation’s Subsidiaries, if any, except to the extent the Corporation is a creditor of such Subsidiaries ranking at least pari passu with such other creditors.

The subordination provided for in this Article 5 shall remain in full force and effect until the entire amount of the Senior Indebtedness has been paid and satisfied in full without regard to, and such subordination shall not be released, discharged, limited or in any way affected or impaired by:

any lack of validity or enforceability of or any limitation of liability under any agreement, document or instalment now or hereafter given in connection with the Senior Indebtedness (including without limitation any security and guarantees, and such agreements, documents and instruments are hereinafter collectively referred to as the “Credit Documents”);

any irregularity, defect, informality, lack of power or due authorization relating to any Credit Document;

any amendment, modification, addition or supplement to any Credit Document;

any extension, renewal, indulgence, compromise, or any other action or inaction, relating to any Credit Document or any person or property;

any taking or abstention from taking of any security for, or any guarantee of, any of the obligations and liabilities of any person arising under any Credit Document whether or not such security or guarantee is given in connection with a Credit Document;

any release, loss, exchange, amendment, modification, addition or supplement to or of any Credit Document or any collateral thereunder (with or without consideration);

any default under, or any lack of due execution, validity or enforceability of, or any irregularity or other defect in, or any failure to perfect, register or file notice of, any Credit Document;

any waiver of or consent to a departure from any requirement or condition precedent contained in any Credit Document;

any exercise or non-exercise, negligent or otherwise, of any right, remedy, power or privilege in respect of any Credit Document;

any change in the parties to, or in the interest of any party in, any Credit Document including, without limitation, any change resulting from an assignment of the interest of a party under any Credit Document;

any method or sequence of application (or subsequent change thereof) at any time or from time to time used by any holder of Senior Indebtedness or the Trustee to apply any proceeds received from any source to the Senior Indebtedness;

any sale, lease, transfer or other disposition by the Corporation or the Trustee or any other Person of any property;

any amalgamation, consolidation or merger of the Corporation or the Trustee or any other Person with or into any Person;

any manner of dealing by any holder of Senior Indebtedness with the Corporation or the Trustee or any other Person;

any bankruptcy, insolvency, reorganization, arrangement or similar proceedings involving or affecting the Corporation or the Trustee or any other Person;

any other circumstances of any nature whatsoever which might otherwise constitute a legal or equitable discharge of or defence against the obligations of the Corporation or the Trustee hereunder (except satisfaction in full of the obligations of the Corporation and the Trustee hereunder); or

any other circumstances (except satisfaction in full of the obligations of the Corporation and the Trustee hereunder);

With respect to the subordination contemplated by this Article 5, the Trustee, and by acceptance of Debentures, each of the Debentureholders, absolutely and unconditionally waives:

notice of any of the matters referred to in Section 5.13(a);

all notices which may be required by statute, rule of law or otherwise to preserve any rights of any holder of Senior Indebtedness, other than notice of an Event of Default;

any right to require the exercise by any holder of Senior Indebtedness of any right, remedy, power or privilege in connection with any Credit Document (including, without limitation, any right to require any holder of Senior Indebtedness to take or exhaust any recourse against the Corporation or any other Person or under the Credit Documents); and

any requirement of diligence or care on the part of any holder of Senior Indebtedness, or the Trustee.

Any Debentures issued hereunder of any series which by their terms are convertible (subject, however, to any applicable restriction on the conversion of Debentures of such series) will be convertible into Freely Tradeable Shares or other securities, 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, in such Debentures, in an Officer’s 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 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 Shares shall be adjusted for in the manner provided in Section 6.5.

The holder of a Debenture desiring to convert such Debenture in whole or in part into Freely Tradeable Shares shall surrender such Debenture to the Trustee at the Designated Office together with the conversion notice on the back of such Debenture or any other written notice in a form satisfactory to the Trustee, in either case duly executed by the holder or its executors or administrators or other legal representatives or its or their attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Trustee, exercising its right to convert such Debenture in accordance with the provisions of this Article. 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, its 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 6.3(b)) as the holder of the number of 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, its nominee(s) or assignee(s), a certificate or other evidence of such Shares.

For the purposes of this Article, a Debenture shall be deemed to be surrendered for conversion on the date (herein called the “Date of Conversion”) on which it is so surrendered in accordance with the provisions of this Article 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 the Designated Office; provided that if a Debenture is surrendered for conversion on a day on which the register of Shares is closed, the person or persons entitled to receive Shares shall become the holder or holders of record of such Shares as at the date on which such registers are next reopened.

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.

The holder of any Debenture of which only a part is converted shall, upon the exercise of its right of conversion surrender the said Debenture to the Trustee, and the Trustee shall cancel the same and shall, if applicable, without charge forthwith certify and deliver to the holder a new Debenture or Debentures in an aggregate principal amount equal to the unconverted part of the principal amount of the Debenture so surrendered.

The holder of a Debenture surrendered for conversion in accordance with this Section 6.3 shall be entitled to receive accrued and unpaid interest in respect thereof up to but excluding the Date of Conversion of such Debenture (less any tax required to be withheld pursuant to Section 7.8, if any) and the 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 Shares pursuant to Section 6.3(b), from which applicable date they will for all purposes be and be deemed to be issued and outstanding as fully paid, non-assessable Shares.

If and whenever at any time prior to the Time of Expiry the Corporation shall (i) subdivide or redivide the outstanding Shares into a greater number of Shares, (ii) reduce, combine or consolidate the outstanding Shares into a smaller number of Shares, or (iii) issue Shares or securities convertible into or exchangeable for Shares to the holders of all or substantially all of the outstanding Shares by way of a dividend or distribution (other than pursuant to any distribution reinvestment or Share purchase plans or similar arrangements), 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 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 Shares resulting from such subdivision, redivision, dividend or distribution (including, in the case where securities convertible into or exchangeable for Shares are distributed, the number of Shares that would have been outstanding had all such securities been exchanged for or converted into Shares on such effective date or record date), or shall, in the case of any of the events referred to in (ii) above, be increased in proportion to the number of outstanding Shares resulting from such reduction, combination or consolidation. Such adjustment shall be made successively whenever any event referred to in this 6.4(a) shall occur. Any such issue of 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 Shares under Subsections (b) and (c) of this Section 6.4.

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 Shares entitling them, for a period expiring not more than 45 days after such record date, to subscribe for or purchase Shares (or securities convertible or exchangeable into 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, 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 Shares outstanding on such record date plus that number of Shares equal to the number arrived at by dividing the aggregate price of the total number of additional Shares offered for subscription or purchase (or the aggregate conversion or exchange price of the convertible or exchangeable securities so offered) by the Current Market Price per Share, and of which the denominator shall be the total number of Shares outstanding on such record date plus the total number of additional Shares offered for subscription or purchase (or into which the convertible or exchangeable 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 based upon the number of Shares (or securities convertible or exchangeable into Shares) actually issued upon the exercise of such options, rights or warrants, as the case may be.

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 Shares of (i) shares of any class other than Shares (other than pursuant to any distribution re-investment or share purchase plans or similar arrangements), (ii) rights, options or warrants (excluding rights, options or warrants entitling the holders thereof for a period of not more than 45 days to subscribe for or purchase Shares or securities convertible or exchangeable into Shares), (iii) evidences of its indebtedness, or (iv) other 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 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 an Investment Dealer chosen by the Corporation, 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 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.

If and whenever at any time prior to the Time of Expiry, there is a reclassification of the Shares or a capital reorganization of the Corporation other than as described in Section 6.4(a) or a consolidation, amalgamation, arrangement or merger of the Corporation with or into any other Person or other entity, or a sale or conveyance of the Property and assets of the Corporation as an entirety or substantially as an entirety to any other 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, consolidation, amalgamation, arrangement or merger, sale or conveyance or liquidation, dissolution or winding up, upon the exercise of such right thereafter, shall be entitled to receive and shall accept, in lieu of the number of 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 merger, amalgamation or consolidation, or to which such sale or conveyance may be made, as the case may be, that such holder of a Debenture would have been entitled to receive on such reclassification, capital reorganization, consolidation, amalgamation, arrangement or merger, sale or conveyance or liquidation, dissolution or winding up, if, on the record date or the effective date thereof, as the case may be, the holder had been the registered holder of the number of 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 6.4(d), the Corporation, its successor, or such purchasing Person or other entity, as the case may be, shall, prior to or contemporaneously with any such reclassification, capital reorganization, consolidation, amalgamation, arrangement, merger, sale or conveyance or liquidation, dissolution or winding up enter into an indenture which shall provide, to the extent possible, for the application of the provisions set forth in this Indenture with respect to the rights and interests thereafter of the holder of Debentures to the end that the provisions set forth in this Indenture shall thereafter correspondingly be made applicable, as nearly equivalent as may be practicable, with respect to any shares or other securities or property to which a holder of Debentures is entitled on the exercise of its acquisition rights thereafter. Any indenture entered into between the Corporation and the Trustee pursuant to the provisions of this Section 6.4(d) shall be a supplemental indenture entered into pursuant to the provisions of Article 16 hereof. 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 6.4(d) and which shall apply to successive reclassifications, capital reorganizations, amalgamations, consolidations, mergers, sales or conveyances or other similar transactions.

In any case in which this Section 6.4 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 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 Shares upon the occurrence of the event requiring such adjustment and the right to receive any dividends or distributions made on such additional Shares declared in favour of holders of record of Shares on and after the Date of Conversion or such later date as such holder would, but for the provisions of this Section 6.4(e), have become the holder of record of such additional Shares pursuant to Section 6.4(b).

The adjustments provided for in this Section 6.4 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 6.4(f) are not required to be made shall be carried forward and taken into account in any subsequent adjustment.

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

In the event of any question arising with respect to the adjustments provided in this Section 6.4, such question shall be conclusively determined by a firm of chartered accountants appointed by the Corporation (who may be the Auditor); 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 (subject to manifest error).

In case the Corporation shall take any action affecting the Shares other than action described in this Section 6.4, which in the opinion of the directors would materially adversely 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, 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 the directors have determined that it is equitable to make no adjustment in the circumstances.

Subject to the prior written consent of the TSX, no adjustment in the Conversion Price shall be made in respect of any event described in Section 6.4(a), Section 6.4(b) or Section 6.4(c) 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.

Except as stated above in this Section 6.4, no adjustment will be made in the Conversion Price for any Debentures as a result of the issuance of Shares at less than the Current Market Price for such Shares on the date of issuance.

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;

shall not be accountable with respect to the validity or value (or the kind or amount) of any 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;

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

shall be entitled to act and rely on, and shall not be required to verify, any adjustment calculation of the Corporation, the directors or the Auditor.

(a)

The Corporation will keep or cause to be kept proper books of record and account, in which full and correct entries shall be made of all financial transactions and the assets and business of the Corporation in accordance with IFRS.

(b)

The Corporation will take all reasonable steps and actions and do all such acts and things as may be required to: (i) maintain (as long as it meets the minimum listing requirements of such institution) the listing and posting for trading of the Initial Debentures, if listed, and the Shares on the TSX, and (ii) maintain its status as a reporting issuer (or the equivalent thereof) in Alberta, British Columbia and Ontario not in default of the requirements of Applicable Securities Legislation.

(c)

The Corporation shall maintain an office or agency at each place of payment for any Debentures where the Debentures may be presented or surrendered for payment, or for registration of transfer or exchange, and where notices and demands to or upon the Corporation in respect of such Debentures and this Indenture may be served. The Corporation will give prompt written notice to the Trustee of the location, and any change in the location, of any such office or agency. If at any time the Corporation shall fail to maintain such required office or agency or shall fail to furnish to the Trustee the address of any such office or agency, such presentations, surrenders, notices and demands may be made or served at the Designated Office and the Corporation hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

(d)

The Corporation shall deliver to the Trustee within 90 days after the end of each fiscal year of the Corporation (and at any other reasonable time upon demand by the Trustee) an Officer’s Certificate stating that the Corporation has complied with, in all material respects, all requirements of the Corporation contained in this Indenture that, if not complied with, in all material respects, would, with the giving of notice, lapse of time, or otherwise, constitute an Event of Default. If an Event of Default shall have occurred, the certificate shall describe the nature and particulars of the Event of Default and its current status and steps taken or proposed to be taken to eliminate such circumstances and remedy such Event of Default, as the case may be.

The Corporation will, at the relevant times and upon exercise of the relevant rights or elections, comply and take all reasonable measures necessary to comply at all times with Section 4.6(c) and Section 4.10(c) including, without limitation, make application for any order, ruling, registration or filing or give any notice required under Applicable Securities Legislation.

The Corporation shall not declare or pay any cash distribution on any Shares at any time after the occurrence of an Event of Default caused by the failure to pay interest on the Debentures when due and until such Event of Default has been cured or waived.

Notwithstanding anything herein contained to the contrary, (i) all payments in excess of $25 million in Canadian dollars (or such other amount as determined from time to time by the Canadian Payments Association) shall be made by the use of the LVTS; and (ii) in the event that payment must be made to CDS Clearing and Depository Services Inc., the Corporation shall remit payment to the Trustee by LVTS.

The Corporation shall file with the Trustee within 15 days after the filing thereof with the Ontario Securities Commission, copies of the Corporation’s annual information form and such information, documents and other reports that the Corporation is required to file with the Ontario Securities Commission and deliver to the Corporation’s shareholders. Notwithstanding that the Corporation may not be required to remain subject to the reporting requirements of the Ontario Securities Commission, the Corporation shall provide to the Trustee (a) within 90 days after the end of each fiscal year, the annual financial statements of the Corporation, and (b) within 45 days after the end of each of the first three fiscal quarters of each fiscal year, interim financial statement of the Corporation which shall, at a minimum, contain such information as is required to be provided in quarterly reports under Applicable Securities Laws to security holders of a company with securities listed on the TSX, whether or not the Corporation has any of its securities so listed. Each of such reports will be prepared in accordance with applicable Canadian disclosure requirements and IFRS. The Corporation will be deemed to have filed with, or provided to, the Trustee any such documentation which it has filed on SEDAR on the date of filing of such documentation. The Corporation will provide copies of such information, documents and reports to holders of Debentures upon request. Upon receipt of financial statements required to be delivered to the Trustee, the Trustee shall, while such statements are current, maintain custody of same and make same available for inspection by Debenture holders on their reasonable request. No obligation shall rest with the Trustee to analyze such statements, or evaluate the performance of the Corporation as indicated therein, in any manner whatsoever.

The Corporation confirms that as at the date of execution of this Indenture it does not have a class of securities registered pursuant to Section 12 of the US Securities Exchange Act or have a reporting obligation pursuant to Section 15(d) of the US Securities Exchange Act. The Corporation covenants that in the event that (i) any class of its securities shall become registered pursuant to Section 12 of the US Securities Exchange Act or the Corporation shall incur a reporting obligation pursuant to Section 15(d) of the US Securities Exchange Act, or (ii) any such registration or reporting obligation shall be terminated by the Corporation in accordance with the US Securities Exchange Act, the Corporation shall promptly deliver to the Trustee an officer’s certificate (in a form provided by the Trustee) notifying the Trustee of such registration or termination and such other information as the Trustee may require at the time. The Corporation acknowledges that the Trustee is relying upon the foregoing representation and covenants in order to meet certain SEC obligations with respect to those clients who are filing with the SEC.

The Corporation shall make all payments of principal, premium (if any) and interest (including interest on amounts in default) on the Debentures without withholding of or deduction for or on account of any present or future taxes imposed or levied by any taxing authority unless such taxes are required to be withheld or deducted by the Corporation by law or by the interpretation or administration thereof, or upon demand of the taxing authority. Whenever in this Indenture the Corporation is obligated to make a payment in respect of which it is so required by law or by the interpretation or administration thereof to withhold or deduct a sum in respect of taxes, the provision shall be read and construed so as to permit such deduction or withholding (whether or not explicitly stated in connection with the particular payment obligation). The Corporation shall make any withholdings or deductions in respect of taxes required by law or by the interpretation or administration thereof and shall remit the full amount withheld or deducted to the relevant taxing authority in accordance with applicable law and shall provide the Trustee with full particulars thereof.

Where Subsection (a) applies on a conversion or on a redemption or repayment of the Debentures with Shares or in any other circumstance where the Corporation is not making a cash payment to a Debentureholder sufficient to satisfy the withholding required under Subsection (a), the Trustee, on the Written Direction of the Corporation but for the account of such holder, shall provide reasonable assistance to effect the sale, through the investment banks, brokers or dealers selected by the Corporation, out of the Freely Tradeable Shares issued by the Corporation for this purpose, such number of Freely Tradeable Shares that 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. In the event the Trustee sells such Freely Tradeable Shares pursuant to this Section 7.8, the procedures set forth in Article 10 of this Indenture shall apply mutatis mutandis to such sale.

The Trustee shall have no obligation to verify any payments under the Tax Act or any provision of provincial, territorial, 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 inccurred, other than those attributable to the negligence or willful misconduct of the Trustee, 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.

failure for 15 days to pay interest on the Debentures when due;

failure to pay principal or premium, if any, on the Debentures when due whether at maturity, upon redemption or pursuant to the Put Right in connection with a Change of Control, by declaration of acceleration or otherwise;

default in the observance or performance of any material covenant or condition of this Indenture by the Corporation which remains unremedied for a period of 30 days after notice in writing has been given by the Trustee to the Corporation specifying such default and requiring the Corporation to remedy such default;

if a decree or order of a court having jurisdiction is entered adjudging the Corporation a bankrupt or insolvent under the Bankruptcy and Insolvency Act (Canada) or any other bankruptcy, insolvency or analogous laws of Canada or any province or territory thereof, or issuing sequestration or process of execution against, or against any substantial part of, the property of the Corporation, or appointing a receiver of, or of any substantial part of, the property of the Corporation 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 45 days or any substantial part of the property of the Corporation shall be sequestered or attached and shall not be returned to the possession of the Corporation or released from such attachment, as the case may be, whether by filing of a bond or stay or otherwise within 45 consecutive days thereafter;

if the Corporation 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 of Canada or any province or territory thereof, or consents to the filing of any such petition or to the appointment of a receiver, or liquidator or trustee or assignee in bankruptcy or insolvency for it, or of any substantial part of the property of the Corporation or makes a general assignment for the benefit of creditors, or is unable to or admits in writing its inability to pay its debts generally as they become due, or any corporate action shall be taken by the Corporation in furtherance of any of the aforesaid actions;

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; or

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

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 66^2/3% of the principal amount of Debentures then outstanding or by Extraordinary Resolution of Debentureholders at a meeting held in accordance with Article 13 hereof, to instruct the Trustee to waive any Event of Default except a default in the payment of the principal of, or premium, if any, or interest on any Debentures, or in respect of a covenant or provision hereof that under this Indenture cannot be modified or amended without the consent of the holder of each outstanding Debenture of such series of Debentures affected and the Trustee shall thereupon waive the Event of Default 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 nonobservance or nonperformance by the Corporation of any covenant applicable only to one or more series of Debentures, then the holders of not less than 66^2/3% of the principal amount of the outstanding Debentures of those 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

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 reasonable 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.

all overdue interest on all Debentures;

the principal of (and premium, if any, on) any of the Debentures which have become due otherwise than by such declaration of acceleration, and interest thereon at the rate or rates prescribed therefor in such Debentures; and

to the extent that payment of such interest is lawful and applicable, interest upon overdue instalments of interest at the rate or rates prescribed therefor in such Debentures; and

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 the said 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 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 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.

Except as herein otherwise expressly provided, any moneys 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 moneys in the hands of the Trustee available for such purpose, as follows:

first, in payment or in reimbursement to the Trustee of its compensation, costs, charges, expenses, borrowings, advances or other moneys 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;

second, but subject as hereinafter in this Section 8.7 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

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

The Trustee shall not be bound to apply or make any partial or interim payment of any moneys coming into its hands if the amount so received by it, after reserving therefrom such amount as the Trustee may think necessary to provide for the payments mentioned in Section 8.7(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 moneys 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 or distribution hereunder.

The holders of at least a majority in principal amount of the outstanding Debentures, may direct the time, method and place (in Ontario) of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it with respect to the Debentures; and take any other action authorized to be taken by or on behalf of the holders of any specified aggregate principal amount of Debentures under any provisions of this Indenture or under all applicable laws.

The Trustee may refuse to follow any direction that conflicts with law, this Indenture or any Extraordinary Resolution.

the Corporation shall be entitled to pay or deliver to the Trustee and direct the Trustee to set aside; or

in respect of moneys or Shares in the hands of the Trustee which may or should be applied to the payment of the Debentures, the Corporation shall be entitled to direct the Trustee to set aside; or

if the redemption was pursuant to notice given by the Trustee, the Trustee may itself set aside;

The Corporation shall be deemed to have fully paid, satisfied and discharged all of the outstanding Debentures of any series and the Trustee, at the expense of the Corporation, shall execute and deliver proper instruments acknowledging the full payment, satisfaction and discharge of such Debentures, when, with respect to all of the outstanding Debentures or all of the outstanding Debentures of any series, as applicable, either:

the Corporation has deposited or caused to be deposited with the Trustee as trust funds or property in trust for the purpose of making payment on such Debentures, an amount in money or Shares, if applicable, sufficient to pay, satisfy and discharge the entire amount of principal, premium, if any, and interest, if any, to maturity or any repayment date or Redemption Dates, as the case may be, of such Debentures; or

the Corporation has deposited or caused to be deposited with the Trustee as trust property in trust for the purpose of making payment on such Debentures:

if the Debentures are issued in Canadian dollars, such amount in Canadian dollars or direct obligations of, or obligations the principal and interest of which are guaranteed by, the Government of Canada or Shares, if applicable; or

if the Debentures are issued in a currency or currency unit other than Canadian dollars, such amount in such currency or currency unit or direct obligations of, or obligations the principal and interest of which are guaranteed by, the Government of Canada or the government that issued the currency or currency unit in which the Debentures are payable or Shares, if applicable; as will, together with the income to accrue thereon and reinvestment thereof, be sufficient to pay and discharge the entire amount of principal and accrued and unpaid interest to maturity or any repayment date, as the case may be, of all such Debentures;

the Corporation has paid, caused to be paid or made provisions to the satisfaction of the Trustee for the payment of all other sums payable with respect to all of such Debentures (together with all applicable expenses of the Trustee in connection with the payment of such Debentures); and

the Corporation has delivered to the Trustee an Officer’s Certificate stating that all conditions precedent herein provided relating to the payment, satisfaction and discharge of all such Debentures have been complied with.

Upon the satisfaction of the conditions set forth in this Section 9.5 with respect to all the outstanding Debentures, or all the outstanding Debentures of any series, as applicable, the terms and conditions of the Debentures, including the terms and conditions with respect thereto set forth in this Indenture (other than those contained in Article 2, Article 4, Article 6, Section 8.5 and Section 15.15 and the provisions of Article 1 pertaining to Article 2, Article 4, Article 6, Section 8.5 and Section 15.15) shall no longer be binding upon or applicable to the Corporation.

Any funds or obligations deposited with the Trustee pursuant to this Section 9.5 shall be denominated in the currency or denomination of the Debentures in respect of which such deposit is made.

If the Trustee is unable to apply any money or securities in accordance with this Section 9.5 by reason of any legal proceeding or any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Corporation’s obligations under this Indenture and the affected Debentures shall be revived and reinstated as though no money or securities had been deposited pursuant to this Section 9.5 until such time as the Trustee is permitted to apply all such money or securities in accordance with this Section 9.5, provided that if the Corporation has made any payment in respect of principal, premium or interest on Debentures or, as applicable, other amounts because of the reinstatement of its obligations, the Corporation shall be subrogated to the rights of the holders of such Debentures to receive such payment from the money or securities held by the Trustee.

(a)

Provided that no Event of Default has occurred and is continuing and that all necessary regulatory approvals have been obtained (including any required approval of any stock exchange on which the Debentures or Shares are then listed), the Corporation shall have the right, at any time and from time to time, to make a Share Interest Payment Election in respect of any Interest Obligation, in whole or in part, by delivering a Share Interest Payment Election Notice to the Trustee by 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 Shares are then listed, and (ii) the day which is 15 Business Days prior to the Interest Payment Date to which the Share Interest Payment Election relates.

(b)

Upon receipt of a Share Interest Payment Election Notice, the Trustee shall, provided that all necessary regulatory approvals have been obtained and in accordance with this Article 10 and such Share Interest Payment Election Notice, deliver Share Bid Requests, in a form to be provided by the Corporation and satisfactory to the Trustee and its counsel acting reasonably, to the investment banks, brokers or dealers identified by the Corporation in its absolute discretion or sell Shares in the open market on any stock exchange on which the Shares are then listed, as specified in the Share Interest Payment Election Notice. In connection with the Share Interest Payment Election, the Trustee shall have the power to: (i) accept delivery of the Shares from the Corporation and process the Shares in accordance with the Share Interest Payment Election Notice, (ii) accept bids with respect to, and consummate sales of, such Shares, each as the Corporation shall direct in its absolute discretion, through the investment banks, brokers or dealers identified by the Corporation in the Share Interest Payment Election Notice, (iii) sell Shares in the open market on any stock exchange on which the Shares are then listed, (iv) invest the proceeds of such sales in accordance with the provisions of Section 15.9 and/or use such proceeds to pay all or part of the Interest Obligation in respect of which the Share Interest Payment Election was made, and (v) perform any other action necessarily incidental thereto.

The Share Interest Payment Election Notice shall provide confirmation from the Corporation that all necessary regulatory approvals have been obtained and shall also provide for, and all bids, if any, 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 Shares on the Share Delivery Date, to withdraw the Share Interest Payment Election and each related Share Bid Request, whereupon the Corporation shall be obliged to pay in cash the amount payable pursuant to the Interest Obligation in respect of which the Share Interest Payment Election Notice has been delivered.

Any sale of 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 Share Interest Payment Election shall take place concurrently on the Share Delivery Date.

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

The Trustee shall inform the Corporation promptly following receipt of any bid or bids for Shares solicited pursuant to the 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. 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 Share Delivery Date, enter into Share Purchase Agreements in a form to be provided by the Corporation and satisfactory to the Trustee and its counsel acting reasonably, and shall comply with all Applicable Securities Laws, including the securities rules and regulations of any stock exchange on which the Shares are then listed. The Corporation shall pay all fees and expenses in connection with the Share Purchase Agreements including the fees and commissions charged by the investment banks, brokers and dealers and the standard fees of the Trustee generally charged for this service.

Provided that (i) all conditions specified in each Share Purchase Agreement to the closing of all sales thereunder have been satisfied, other than the delivery of the Shares to be sold thereunder against payment of the purchase price thereof, and (ii) the purchasers under each Share Purchase Agreement shall be ready, willing and able to perform thereunder, in each case on the Share Delivery Date, the Corporation shall, on the Share Delivery Date, issue and deliver to the Trustee the Shares to be sold on such date, an amount in cash equal to the difference between the applicable Interest Obligation and the anticipated net proceeds of the Shares to be sold and an Officer’s Certificate to the effect that all conditions precedent to such sales, including those set forth in this Indenture and in each Share Purchase Agreement, have been satisfied. Upon such deliveries, the Trustee shall consummate such sales on such Share Delivery Date by the delivery of the Shares to such purchasers against payment in immediately available funds of the purchase price therefor.

The Corporation agrees that any Shares issued pursuant to this Article 10 shall be issued for an amount equal to the sale price of such Shares realized by the Trustee, with the effect that the Trustee will neither realize a gain or loss with respect to the sale of such Shares.

The Trustee shall, on the Share Delivery Date, use the sale proceeds of the Shares (together with any cash received from the Corporation) to purchase, on the direction of the Corporation in writing, Authorized Investments which mature prior to the applicable Interest Payment Date and which the Trustee is required to hold until maturity (the “Share Proceeds Investment”) and shall, on such date, deposit the balance, if any, of such sale proceeds in the Property Account for such Debentures. At least one Business Day prior to the Interest Payment Date, the Trustee shall deposit amounts from the proceeds of the Share Proceeds Investment in the Property Account to bring the balance of the Property Account to the Share Interest Payment Election Amount to the extent that the Trustee has been provided sufficient funds to do so.

On the Interest Payment Date, the Trustee shall pay the funds held in the Property Account to the holders of record of the Debentures on the Record Date of such 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 Share Proceeds Investment or otherwise in excess of the Share Interest Payment Election Amount to the Corporation.

Neither the making of a Share Payment Election nor the consummation of sales of Shares on a 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 amount payable pursuant to the Interest Obligation on such date, or (ii) entitle such holders to receive any Shares in satisfaction of such Interest Obligation.

Subject to the provisions of Article 12, the Corporation shall not enter into any transaction or series of transactions whereby all or substantially all of its undertaking, property or assets would become the property of any other Person (herein called a “Successor”) whether by way of reorganization, consolidation, amalgamation, arrangement, merger, transfer, sale or otherwise, unless:

prior to or contemporaneously with the consummation of such transaction the Corporation and the Successor shall have executed such instruments and done such things as, in the opinion of Counsel, are necessary or advisable to establish that upon the consummation of such transaction:

the Successor will have assumed all the covenants and obligations of the Corporation under this Indenture in respect of the Debentures;

the Debentures will be valid and binding obligations of the Successor entitling the holders thereof, as against the Successor, to all the rights of Debentureholders under this Indenture, including the rights of conversion set out in Article 2 and Article 6; and

in the case of the entity organized otherwise than under the laws of the Province of Ontario, the Successor shall attorn to the jurisdiction of the courts of the Province of Ontario;

such transaction, in the opinion of Counsel, shall be on such terms as to substantially preserve and not materially and adversely impair any of the rights and powers of the Trustee or of the Debentureholders hereunder; and

no condition or event shall exist as to the Corporation (at the time of such transaction) or the Successor (immediately after such transaction) and after giving full effect thereto or immediately after the Successor shall become liable to pay the principal monies, premium, if any, interest and other monies due or which may become due hereunder, which constitutes or would constitute an Event of Default hereunder.

within the time provided in the Offer for its acceptance or within 45 days after the date the Offer is made, whichever period is the shorter, the Offer is accepted by Debentureholders representing at least 90% of the outstanding principal amount of the Debentures, other than the Offeror’s Debentures;

the Offeror is bound to take up and pay for, or has taken up and paid for the Debentures of the Debentureholders who accepted the Offer; and

the Offeror complies with Section 12.3 and Section 12.5;

Debentureholders holding at least 90% of the principal amount of all outstanding Debentures, other than Offeror’s Debentures, have accepted the Offer;

the Offeror is bound to take up and pay for, or has taken up and paid for, the Debentures of the Debentureholders who accepted the Offer;

Dissenting Debentureholders must transfer their respective Debentures to the Offeror on the terms on which the Offeror acquired the Debentures of the Debentureholders who accepted the Offer within 21 days after the date of the sending of the Offeror’s Notice; and

Dissenting Debentureholders must send their respective Debenture(s) to such Person as the Offeror may direct within 21 days after the date of the sending of the Offeror’s Notice.

do all acts and things and execute and cause to be executed all instruments as in such Person’s opinion, relying on the advice of Counsel, may be necessary or desirable to cause the transfer of the Debentures of the Dissenting Debentureholders to the Offeror;

send to each Dissenting Debentureholder who has complied with Section 12.4 the consideration to which such Dissenting Debentureholder is entitled under this Article 12; and

send to each Dissenting Debentureholder who has not complied with Section 12.4 a notice stating that:

its Debentures have been transferred to the Offeror;

the Person indicated in the Offeror’s Notice or some other Person designated in such notice are holding in trust the consideration for such Debentures; and

the Person indicated in the Offeror’s Notice, or such other Person, will send the consideration to such Dissenting Debentureholder as soon as possible after receiving such Dissenting Debentureholder’s Debenture(s) or such other documents as such Person or such other Person may require in lieu thereof;

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

If the business to be transacted at any meeting by Extraordinary Resolution or otherwise, or any action to be taken or power exercised by instrument in writing under Section 13.15, especially affects the rights of holders of Debentures of one or more series in a manner or to an extent differing in any material way from that in or to which the rights of holders of Debentures of any other series are affected (determined as provided in Section 13.2(c) and Section 13.2(d)), then:

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

the holders of Debentures of an especially affected series shall not be bound by any action taken at a Serial Meeting or by instrument in writing under Section 13.15 unless in addition to compliance with the other provisions of this Article 13:

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

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 especially affected series then outstanding.

Subject to Section 13.2(d), the determination as to whether any business to be transacted at a meeting of Debentureholders, or any action to be taken or power to be exercised by instrument in writing under Section 13.15, 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.

A proposal:

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;

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

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

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

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 votes cast thereat by 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 favourable votes of votes cast thereat by 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 and voted upon on a poll on such resolution, or, pursuant to Section 13.15, rendered by instruments in writing signed by the holders of not less than 66^2/3% of the Debentures then outstanding or Debentures of an applicable series in the case of an action which if taken at a meeting would be a Serial Meeting.

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 until 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 holders of the Debentures then outstanding 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.

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

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.

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.

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 Business Days following the day of mailing. 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 an English language daily newspaper of general circulation in Canada and in a French language daily newspaper of general circulation in the Province of Quebec.

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 the newspaper 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 such Debenture.

Subject to the terms hereof, the Trustee may resign its trust and be discharged from all further duties and liabilities hereunder by giving to the Corporation 60 days notice in writing or such shorter notice as the Corporation may accept as sufficient.
