The Trustee shall not be required to ensure compliance with any law or with rules or regulations thereto or with any rules or regulations of any securities exchange or securities regulatory authority or to conform to general usage in connection with the issue, transfer or exchange of the Debentures. The responsibility for compliance with the foregoing shall be that of the Issuer, or the Debentureholder, as applicable.

2.4 Form and Terms of Initial Debentures

(a) The first series of debentures (the “Initial Debentures” or “Series 3A Debentures”) authorized for issue immediately is limited to an aggregate amount of $63,250,000 and shall be designated as “7% Convertible Unsecured Subordinated Debentures due June 30, 2017”. However, subject to the provisions set out herein, additional Debentures may be issued pursuant to this Indenture after the date hereof.

(b) The Initial Debentures shall be dated as of December 2, 2009, shall mature on June 30, 2017 and shall bear interest from the date of issue at the rate of 7% per annum, payable in equal semi-annual payments in arrears on June 30 and December 31 in each year, except the first such payment to fall due on June 30, 2010 will include accrued and unpaid interest for the period from the issuance of the Initial Debentures to June 30, 2010.

(c) The Initial Debentures will be redeemable by the Issuer in accordance with the terms of Article 4, provided that the Initial Debentures will not be redeemable on or before December 31, 2012 (the “First Call Date”), except in the event of the satisfaction of certain conditions after a Change of Control has occurred as outlined herein. After December 31, 2012, and on or before December 31, 2014, the Initial Debentures may be redeemed in whole at any time or in part from time to time at the option of the Issuer on notice as provided for in Section 4.3 provided that the Current Market Price immediately preceding the date on which such notice of redemption is given is at least 125% of the Conversion Price and the Issuer shall have provided to the Trustee an Officer’s Certificate confirming such Current Market Price and in addition thereto, at the time of redemption, the Issuer shall pay to the Debentureholder accrued and unpaid interest. The Redemption Price for the Initial Debentures will be a price equal to their principal

- 13 -

amount excluding accrued and unpaid interest. After December 31, 2014 and prior to the Maturity Date, the Initial Debentures may be redeemed at the option of the Issuer in whole or in part from time to time on notice as provided for in Section 4.3 hereof at the Redemption Price, irrespective of the Current Market Price and, in addition thereto, at the time of redemption, the Issuer shall pay to the Debentureholder accrued and unpaid interest. The Redemption Notice for the Initial Debentures shall be in the form of Schedule “B”.

(d) The Initial Debentures will be subordinated to the Senior Indebtedness of the Issuer in accordance with the provisions of Article 5; provided however, that nothing contained in this Indenture shall in any way or manner restrict the Issuer from incurring, directly or indirectly, any additional indebtedness.

(e) Upon and subject to the provisions and conditions of Article 6, the Debentureholder of each Initial Debenture shall have the right at such Debentureholder’s option, at any time prior to 5 p.m. Toronto time on the earlier of the last Business Day immediately preceding June 30, 2017 and the last Business Day immediately preceding the date specified by the Issuer for redemption of the Initial Debentures by notice to the Debentureholders of the Initial Debentures in accordance with Sections 2.4(c) and 4.3 (the earlier of which will be the “Time of Expiry” for the purposes of Article 6 in respect of the Initial Debentures), to convert 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 Issuer Shares at the Conversion Price in effect on the Date of Conversion (as defined in Section 6.4(b)). No Initial Debentures may be converted on any Interest Payment Date and during the five Business Days preceding any Interest Payment Date or during the period beginning five Business Days before the day of mailing of a Redemption Notice and ending on the date of mailing of such Redemption Notice.

The Conversion Price in effect on the date hereof for each Issuer Share to be issued upon the conversion of Initial Debentures shall be equal to $4.20 such that approximately 238.1 Issuer Shares shall be issued for each $1,000 principal amount of Initial Debentures so converted. No adjustment will be made for distributions on Issuer Shares issuable upon conversion. Debentureholders converting their Initial Debentures following a Redemption Notice shall be entitled to receive, in addition to the applicable number of Issuer Shares, accrued and unpaid interest in respect thereof for the period up to but excluding the Date of Conversion from the latest Interest Payment Date. The Conversion Price applicable to and the Issuer Shares receivable on the conversion of the Initial Debentures is subject to adjustment pursuant to the provisions of Section 6.5.

(f) On redemption or on maturity of the Initial Debentures, the Issuer may, at its option and subject to the provisions of Section 4.6 and Section 4.10 as applicable, and subject to regulatory approval, elect to satisfy its obligation to pay all or a portion of the aggregate principal amount of the Initial Debentures by issuing and

- 14 -

delivering to the Debentureholders of Initial Debentures, Freely Tradeable Issuer Shares. If the Issuer elects to exercise such option, it shall deliver a Redemption Notice (as defined in Section 4.3) or a maturity notice (the “Maturity Notice”) to the Debentureholders of the Initial Debentures and the Trustee in the form of Schedule “B” or Schedule “C”, respectively.

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

The Initial Debentures shall be issued as Global Debentures and the Depository for the Initial Debentures shall be The Canadian Depository for Securities Limited. The Global Debentures shall be registered in the name of The Canadian Depository for Securities Limited (or any nominee of the Depository). No Beneficial Holder will receive definitive certificates representing their interest in Debentures except as provided in Section 3.2. A Global Debenture 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 as provided in Section 3.2.

(h) (i) If a Change of Control occurs, the Issuer will be required to make an offer in writing to purchase all or, at the option of the Debentureholder, any part (equal to $1,000 or an integral multiple thereof) of each Debentureholder’s Initial Debentures pursuant to the offer described in this Section 2.4(h) (the “Change of Control Offer”) on the terms set forth herein. Pursuant to the Change of Control Offer, the Issuer will be required to offer payment in cash equal to 101% of the aggregate principal amount of Initial Debentures purchased together with accrued and unpaid interest on such Initial Debentures up to, but excluding, the date of purchase (the “Offer Price”).

- 15 -

(ii) Within two Business Days following the occurrence of a Change of Control, the Issuer will give written notice (the “Change of Control Notice”) to the Trustee describing the transaction or transactions that constitute the Change of Control and offering to purchase the Initial Debentures on the date specified in the Change of Control Notice, which date will be, unless otherwise required by applicable securities legislation, no earlier than 35 days from and not later than the 60^th day following the date such Change of Control Notice is given (the “Change of Control Payment Date”). Such Change of Control Notice shall state whether the Offer Price will be payable in cash or satisfied, in whole or in part, by the issuance of Issuer Shares, as contemplated in Section 2.4(h)(xiii). The Trustee will, as soon as practicable thereafter, and in any event no later than two Business Days after receiving a Change of Control Notice from the Issuer, provide written notice to the holders of the Initial Debentures describing the transaction or transactions that constitute the Change of Control and such notice shall include details of the Change of Control Offer under the terms of this Indenture, including the right of Debentureholder to accept the Change of Control Offer in respect of all or a portion (in a minimum amount of $1,000 principal amount and multiples thereof) of their Initial Debentures, details regarding whether the Offer Price is to be paid in cash or, in whole or in part, in Issuer Shares and the right of the Corporation to redeem untendered Debentures under certain circumstances. The Issuer must comply with the requirements of applicable securities laws and regulations in connection with the purchase of the Initial Debentures as a result of a Change of Control.

(iii) A Debentureholder may exercise its rights specified in this Section 2.4(h) upon delivery of a written notice of the exercise of such rights, in the form attached hereto as Schedule F, to the Trustee not less than five Business Days prior to the date which is 30 days after the date the Trustee delivers notice of the Change of Control Offer to the Debentureholder 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.

(iv) If holders of 90% or more of the aggregate principal amount of the Initial Debentures outstanding on the date that the Issuer delivers the Change of Control Notice to the Trustee accept the Change of Control Offer, the Issuer shall have the right upon written notice provided to the Trustee within 10 days following the expiry of the Change of Control Offer to redeem all of the remaining Initial Debentures on such date for an amount equal to the Offer Price in respect of such Initial Debentures (the “90% Redemption Right”).

- 16 -

(v) Upon receipt of notice that the Issuer shall exercise the 90% Redemption Right and acquire the remaining Initial Debentures, the Trustee shall promptly provide written notice to all Debentureholders that did not previously accept the Change of Control Offer that:

(A) The Issuer has exercised the 90% Redemption Right and will purchase all outstanding Initial Debentures on the Change of Control Payment Date at the Offer Price, including a calculation of such Debentureholder’s Offer Price;

(B) They must transfer their Initial Debentures to the Trustee on the same terms as those Debentureholders that accepted the Change of Control Offer 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

(C) The rights of such Debentureholder under the terms of the Initial Debentures cease as of the Change of Control Payment Date provided the Issuer has paid the Offer Price to, or to the order of, the Trustee and thereafter the Initial Debentures shall not be considered to be outstanding and the Debentureholder shall not have any right except to receive the Offer Price upon surrender and delivery of such Debentureholder’s Initial Debentures in accordance with this Indenture.

(vi) Subject to Section 2.4(h)(xiii), the Issuer shall, on or before 11:00 a.m., Toronto time on the Business Day immediately prior to the Change of Control Payment Date, deposit with the Trustee or any paying agent to the order of the Trustee, such sums of money, as may be sufficient to pay the Offer Price of the Initial Debentures to be purchased or redeemed by the Issuer on the Change of Control Payment Date, provided the Issuer may elect to satisfy this requirement by providing the Trustee with a certified cheque for such amounts required under this Section 2.4(h)(vi) post-dated to the Change of Control Payment Date or the Issuer may satisfy this requirement by an electronic funds transfer of such sums of money on the Change of Control Payment Date. To the extent requested by the Trustee, the Issuer 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, 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 Debentureholders of such Initial Debentures the Offer Price to which they are entitled on the Issuer’s purchase or redemption.

- 17 -

(vii) In the event that one or more of such series of Initial Debentures being purchased in accordance with this Section 2.4(h) becomes subject to purchase in part only, upon surrender of such Initial Debentures for payment of the Total Offer Price, the Issuer shall execute and the Trustee shall certify and deliver without charge to the Debentureholder thereof or upon the Debentureholder’s order, one or more new Initial Debentures for the portion of the principal amount of the Initial Debentures not purchased.

(viii) Initial Debentures for which Debentureholders have accepted the Change of Control Offer and Initial Debentures which the Issuer has elected to redeem in accordance with this Section 2.4(h) shall become due and payable at the Offer Price on the Change of Control Payment 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 Change of Control Payment Date, if the money necessary to purchase or redeem the Initial Debentures shall have been deposited as provided in this Section 2.4(h) and affidavits or other proofs satisfactory to the Trustee as to the publication and/or mailing of such notices shall have been lodged with it, interest on the 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.

(ix) In case the Debentureholder of any Initial Debenture to be purchased or redeemed in accordance with this Section 2.4(h) shall fail on or before the Change of Control Payment Date to so surrender such Debentureholder’s Initial Debenture or duly endorsed form of transfer or shall not within such time accept payment of the moneys payable, or give such receipt therefor, if any, as the Trustee may require, such moneys may be set aside in trust without interest, either in the deposit department of the Trustee or in a chartered bank, and such setting aside shall for all purposes be deemed a payment to the Debentureholder of the sum so set aside and, 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 of the moneys so paid and deposited, upon surrender and delivery of such Debentureholder’s Initial Debenture of the Offer Price. In the event that any money required to be deposited hereunder with the Trustee or any depositary or paying agent on account of principal, premium, if any, or interest, if any, on the Initial Debentures issued hereunder shall remain so deposited for a period of ten years from the

- 18 -

Change of Control Payment Date, then such moneys, together with any accumulated interest thereon, shall at the end of such period be paid over or delivered over by the Trustee or such depositary or paying agent to the Issuer and the Trustee shall not be responsible to Debentureholders for any amounts owing to them.

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

(xi) The Issuer will publicly announce the results of the purchases made pursuant to this Section 2.4(h) as soon as practicable after the Change of Control Payment Date.

(xii) The Issuer will comply with all Applicable Securities Legislation in the event that the Issuer is required to purchase or redeem the Initial Debentures pursuant to this Section 2.4(h).

(xiii) Notwithstanding any other provision of this Indenture, the Issuer shall be entitled at its option, subject to regulatory approval, to deposit with the Trustee or any paying agent to the order of the Trustee, in lieu of all or any portion of the cash which would otherwise be required to be deposited with the Trustee hereunder in payment of the Offer Price, Freely Tradeable Issuer Shares for purposes of making payment of all or any portion of the Offer Price. If the Issuer elects to pay the Offer Price in Freely Tradeable Issuer Shares, the number of such Freely Tradeable Issuer Shares will be determined by dividing the Offer Price by 95% of the Current Market Price in effect on the Change of Control Payment Date, and then multiplying the quotient by the fraction of the Offer Price to be satisfied by Freely Tradeable Issuer Shares. No fractional Issuer Shares shall be issued as payment of the Offer Price but in lieu thereof the Issuer shall satisfy fractional interests by a cash payment equal to the relevant fraction of the fractional interest in a Issuer Share multiplied by the Current Market Price of the Issuer Shares in effect on the Change of Control Payment Date. In all other respects, in paying the Offer Price the Issuer shall be subject to the requirements of Section 2.4(h)(vi) and the Trustee shall, in making payment to holders of such Initial Debentures pursuant to Section 2.4(h)(vi) of the Offer Price, make payment using such Freely Tradeable Issuer Shares. Solely for purposes of this Section 2.4(h)(xiii), the term “Current Market Price” as set forth in Section 1.1 shall be modified to provide that in the event the Issuer Shares are not at the relevant time listed on any stock exchange or traded on the over-the-counter market, the Current Market Price shall be the fair market value of the Issuer Shares as determined by the Issuer, acting reasonably. In the event the Issuer exercises its right pursuant to this Section 2.4(h)(xiii) to deliver Freely Tradeable Issuer Shares, the provisions of paragraphs (c) to (l) inclusive of Section 4.10 shall apply, mutatis mutandis.

- 19 -

(xiv) Upon a Change of Control resulting from a transaction in respect of which 10% or more of the consideration for the Issuer Shares consists of (i) cash or (ii) equity securities or other property that is not traded or intended to be traded immediately following such transaction on a recognized stock exchange, if a holder of the Initial Debentures elects to convert such Initial Debentures prior to the completion of the Change of Control Offer, the Conversion Price will be adjusted as follows (the “Change of Control Conversion Price” or “COCCP”):

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

ECP = is the Conversion Price in effect at the time of the Change of Control;

CP = 25%;

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

t = the number of days from and including the Closing Date to but excluding the First Call Date.

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

2.5 Certification and Delivery of Additional Debentures

The Issuer may from time to time request the Trustee to certify and deliver Additional Debentures of any series by delivering to the Trustee the documents referred to below in this Section 2.5 whereupon the Trustee shall certify such Additional Debentures and cause the same to be delivered in accordance with the Written Direction of the Issuer referred to below or pursuant to such procedures acceptable to the Trustee as may be specified from time to time by a Written Direction of the Issuer. The maturity date, issue date, interest rate (if any) and any other terms of the Additional Debentures of such series shall be set forth in a supplemental indenture determined by or pursuant to such Written Direction of the Issuer. In certifying such Additional Debentures, the Trustee shall be entitled to receive and shall be fully protected acting upon or in relying upon, unless and until such documents have been superseded or revoked:

- 20 -

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

(i) such Written Direction of the Issuer may be delivered by the Issuer to the Trustee prior to the delivery to the Trustee of such Additional Debentures of such series for certification and delivery,

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

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

(iv) if provided for in such procedures, such Written Direction of the Issuer may authorize certification and delivery pursuant to oral or electronic instructions from the Issuer which oral or electronic instructions shall be promptly confirmed in writing (for greater certainty, the Trustee shall not be obliged to accept oral or electronic instructions unless it is satisfied, in its sole discretion, with the procedures therefor);

(c) an opinion of Counsel that all requirements imposed by this Indenture or by law in connection with the proposed issue of Additional Debentures have been complied with, subject to the delivery of certain documents or instruments specified in such opinion; and

2.6 Issue of Global Debentures

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

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

- 21 -

(ii) be delivered by the Trustee to such Depositary or pursuant to such Depositary’s instructions; and

This Debenture may not be transferred to or exchanged for Debentures registered in the name of any Person other than the Depositary or a nominee thereof and no such transfer may be registered except in the limited circumstances described in this 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 this Indenture.”

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

2.7 Execution of Debentures

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

2.8 Certification

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

- 22 -

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

2.9 Interim Debentures or Certificates

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

2.10 Mutilation, Loss, Theft or Destruction

In case any of the Debentures issued hereunder shall become mutilated or be lost, stolen or destroyed, the Issuer, in its discretion, may issue, and thereupon the Trustee shall certify and deliver, a new Debenture upon surrender and cancellation of the mutilated Debenture, or in the case of a lost, stolen or destroyed Debenture, in lieu of and in substitution for the same, and the substituted Debenture shall be in a form approved by the Trustee and shall be entitled to the benefits of this Indenture and rank equally in accordance with its terms with all other Debentures issued or to be issued hereunder. In case of loss, theft or destruction the applicant for a substituted Debenture shall furnish to the Issuer and to the Trustee such evidence of the loss,

- 23 -

theft or destruction of the Debenture as shall be satisfactory to each of them in their discretion and shall also furnish an indemnity satisfactory to each of them in their discretion. The applicant shall pay all reasonable expenses incidental to the issuance of any substituted Debenture.

2.11 Concerning Interest

(a) 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 their issue date or from the last Interest Payment Date to which interest shall have been paid or made available for payment on the outstanding Debentures of that series and date of maturity, whichever shall be the later, or, in respect of Debentures subject to a Periodic Offering, from their issue date or from the last Interest Payment Date to which interest shall have been paid or made available for payment on such Debentures; provided that, in respect of the first interest payment after the original issuance thereof, each Debenture of a series shall bear interest from the later of the issue date of such Debenture and the last Interest Payment Date preceding the issuance of such Debenture.

(b) 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.

2.12 Debentures to Rank Pari Passu

The Debentures will be direct unsecured obligations of the Issuer. Each Debenture of the same series of Debentures will rank pari passu with each other Debenture of the same series (regardless of their actual date or terms of issue) and will rank pari passu or in priority in right of payment to other indebtedness of the Issuer which by the terms of the instrument creating or evidencing such indebtedness is expressed to be pari passu with or subordinate in right of payment to the Debentures. The payment of the principal of, and interest on, the Debentures shall, as provided in Article 5, be subordinated and postponed in light of payment to all Senior Indebtedness (including all payments thereunder). The Debentures are expressed to be pari passu with the outstanding Series 1A debentures and Series 2A debentures of the Corporation issued pursuant to a trust indenture between the Corporation and the Trustee dated October 27, 2009.

- 24 -

2.13 Payments of Amounts Due on Maturity

Except as may otherwise be provided in any supplemental indenture in respect of any series of Debentures and except as otherwise provided in this Indenture, payments of amounts due upon maturity of the Debentures will be made in the following manner. The Trustee will establish and maintain for the residual benefit of the Issuer, a Debt Account for each series of Debentures. Each such Debt Account shall be maintained by and be subject to the control of the Trustee for the purposes of this Indenture. On or before 11:00 a.m., Toronto time on the Business Day immediately prior to each maturity date for Debentures outstanding from time to time under this Indenture, the Issuer will deposit in the applicable Debt Account an amount sufficient to pay the amount payable in respect of such Debentures, (including the principal amount together with any accrued and unpaid interest thereon less any tax required by law to be deducted) provided the Issuer may elect to satisfy this requirement by providing the Trustee with a certified cheque for such amounts required under this Section 2.13 post-dated to the applicable maturity date or the Issuer may satisfy this requirement by an electronic funds transfer of such sums of money on the applicable maturity date. The Trustee, on behalf of the Issuer will pay to each Debentureholder entitled to receive payment the principal amount of and premium (if any) and accrued and unpaid interest on the Debenture (less any tax required to be deducted on the maturity date), upon surrender of the Debenture at the Designated Office. The deposit or making available of such amounts to the applicable Debt Account will satisfy and discharge the liability of the Issuer for the Debentures to which the deposit or making available of funds relates to the extent of the amount deposited or made available (plus the amount of any tax deducted as aforesaid) and such Debentures will thereafter to that extent not be considered as outstanding under this Indenture and such Debentureholder will have no other right in regard thereto other than to receive out of the money so deposited or made available the amount to which it is entitled.

2.14 U.S. 1933 Act Legend on the Debentures

(a) The Debentures and the Issuer Shares issuable pursuant to the terms thereof have not been and will not be registered under the 0000 Xxx. All Debentures and the Issuer Shares issuable pursuant to the terms thereof issued and sold in the United States in reliance on Rule 144A under the 1933 Act, as well as all Debentures and the Issuer Shares issuable pursuant to the terms thereof issued in exchange for or in substitution of the foregoing securities, shall bear the following legend (the “U.S. 1933 Act Legend”):

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “1933 ACT”) OR STATE SECURITIES LAWS. THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT OF THE ISSUER THAT SUCH SECURITIES MAY BE OFFERED, SOLD OR OTHERWISE TRANSFERRED ONLY (A) TO THE ISSUER, (B) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE 1933 ACT, OR (C) INSIDE THE UNITED STATES IN ACCORDANCE WITH (1) RULE 000X XXXXX XXX

- 00 -

0000 XXX OR (2) RULE 144 UNDER THE 1933 ACT, IF AVAILABLE, AND IN EACH CASE IN ACCORDANCE WITH ANY APPLICABLE LOCAL LAWS AND REGULATIONS. THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE LISTED ON THE TORONTO STOCK EXCHANGE; HOWEVER, DELIVERY OF THIS CERTIFICATE MAY NOT CONSTITUTE “GOOD DELIVERY” IN SETTLEMENT OF TRANSACTIONS ON THE TORONTO STOCK EXCHANGE. A NEW CERTIFICATE NOT BEARING THIS LEGEND, DELIVERY OF WHICH WILL CONSTITUTE “GOOD DELIVERY”, MAY BE OBTAINED FROM CIBC MELLON TRUST COMPANY UPON DELIVERY OF THIS CERTIFICATE AND A DULY EXECUTED DECLARATION, IN A FORM SATISFACTORY TO CIBC MELLON TRUST COMPANY AND THE ISSUER, TO THE EFFECT THAT THE SALE OF THE SECURITIES REPRESENTED HEREBY IS BEING MADE IN COMPLIANCE WITH RULE 904 OF REGULATION S UNDER THE 1933 ACT.”

provided, that if the Debentures (or any such Issuer Shares) are being sold under clause (B) above, and provided that the Issuer is a “foreign issuer” within the meaning of Regulation S under the 1933 Act at the time of sale, the U.S. 1933 Act Legend may be removed by providing a declaration to the Trustee, in its capacity as the trustee hereunder and as the transfer agent for the Issuer Shares, as set forth in Schedule “E” hereto (or as the Trustee or the Issuer may prescribe from time to time); and provided, further, that, if any such securities are being sold under clause (C)(2) above, the U.S. 1933 Act Legend may be removed by delivery to the Trustee, in its capacity as the trustee hereunder and as the transfer agent for the Issuer Shares, of an opinion of counsel of recognized standing, reasonably satisfactory to the Issuer, to the effect that the U.S. 1933 Act Legend is no longer required under applicable requirements of the 1933 Act or any applicable local laws or regulations. Provided that the Trustee obtains confirmation from the Issuer that such counsel is satisfactory to it, the Trustee shall be entitled to rely on such opinion of counsel without further inquiry.

(b) Prior to the issuance of the Debentures, the Issuer shall notify the Trustee, in writing, concerning which Debentures are to bear the U.S. 1933 Act Legend. The Trustee will thereafter maintain a list of all registered Debentureholders from time to time of Legended Debentures.

2.15 Payment of Interest

The following provisions shall apply to Debentures, except as otherwise provided in Section 2.4(b) or elsewhere in this Indenture or specified in a resolution of the Board of Directors, on behalf of the Issuer, Officer’s Certificate or supplemental indenture relating to a particular series of Additional Debentures:

(a) As interest becomes due on each Debenture (except on conversion, at maturity or on redemption, when interest may at the option of the Issuer be paid upon

- 26 -

surrender of such Debenture), the Issuer, either directly or through the Trustee or any agent of the Trustee, shall send or forward by prepaid ordinary mail, electronic transfer of funds or such other means as may be agreed to by the Trustee, payment of such interest (less any tax required to be withheld therefrom) to the order of the registered Debentureholder appearing on the registers maintained by the Trustee at the close of business on the 5^th Business Day prior to the applicable Interest Payment Date and addressed to the Debentureholder at the Debentureholder’s last address appearing on the register, unless such Debentureholder otherwise directs. If payment is made by cheque such cheque shall be forwarded as soon as practicable following the date on which interest becomes due and if payment is made by other means (such as electronic transfer of funds), such payment shall be made in a manner whereby the Debentureholder receives credit for such payment on the date such interest on such Debenture becomes due. The mailing of such cheque or the making of such payment by other means shall, to the extent of the sum represented thereby, plus the amount of any tax withheld as aforesaid, satisfy and discharge all liability for interest on such Debenture, unless in the case of payment by cheque, such cheque 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 Issuer will issue to such Person a replacement cheque or other payment for a like amount upon being furnished with such evidence of non-receipt as it shall reasonably require and upon being indemnified to its satisfaction. Notwithstanding the foregoing, if the Issuer is prevented by circumstances beyond its control (including, without limitation, any interruption in mail service) from making payment of any interest due on each Debenture in the manner provided above, the Issuer may make payment of such interest or make such interest available for payment in any other manner acceptable to the Trustee with the same effect as though payment had been made in the manner provided above.

(b) Notwithstanding Section 2.15(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 on such Interest Payment Date to the Depositary or its nominee for subsequent payment to Beneficial Holders in that Global Debenture, unless the Issuer and the Depositary otherwise agree. The record date for the payment of interest will be that day which is the 5^th Business Day prior to the applicable Interest Payment Date. None of the Issuer, 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.

- 27 -

2.16 Deductions for Taxes

If the Issuer shall be required by applicable law to deduct or withhold any amount of taxes from or in respect of any amount payable under this Indenture, the Issuer shall make such deductions or withholdings, and the Issuer shall pay the amount so deducted or withheld to the relevant governmental authority in accordance with applicable law and all amounts so deducted or withheld shall be treated as having been paid to the relevant Debentureholder under this Indenture. The Issuer shall furnish to the Trustee evidence of remittance of such taxes made by it within 30 days after the date of any such remittance.

Upon surrender by the Depositary of the certificate(s) representing the Global Debentures and receipt of new registration instructions from the Depositary, the Trustee shall deliver the definitive Debenture certificates for such Debentures to the Debentureholders thereof in accordance with the new registration instructions and thereafter, the registration and transfer of such Debentures will be governed by Section 3.1 and the remaining Sections of this Article 3.

The transferee of a Debenture shall be entitled, after the appropriate form of transfer is lodged with the Trustee or other registrar and upon compliance with all other conditions in that behalf required by this Indenture or by law, to be entered on the register as the owner of such Debenture free from all equities or rights of set-off or counterclaim between the Issuer and the transferor or any previous Debentureholder of such Debenture, save in respect of equities of which the Issuer is required to take notice by statute or by order of a court of competent jurisdiction.

3.4 No Notice of Trusts

Any Debentures tendered for exchange shall be surrendered to the Trustee. The Issuer shall execute and the Trustee shall certify all Debentures necessary to carry out exchanges as aforesaid.

ARTICLE 4

REDEMPTION AND PURCHASE OF DEBENTURES

4.1 Applicability of Article

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

4.2 Partial Redemption

If less than all the Debentures of any series for the time being outstanding are at any time to be redeemed, or if a portion of the Debentures being redeemed are being redeemed for cash and a portion of such Debentures are being redeemed by the payment of Freely Tradeable Issuer Shares pursuant to Section 4.6, the Debentures to be so redeemed shall be selected by the Trustee on a pro rata basis to the nearest multiple of $1,000, or such other amount as determined by the Issuer, in accordance with the principal amount of the Debentures registered in the name of each Debentureholder or in such other manner as the Trustee deems

- 33 -

equitable, subject to the approval of the TSX, as may be required from time to time. Unless otherwise specifically provided in the terms of any series of Debentures, no Debenture shall be redeemed in part unless the principal amount redeemed is $1,000 or such other amount as determined by the Issuer, or a multiple thereof, as applicable. For this purpose, the Trustee may make, and from time to time vary, regulations with respect to the manner in which such Debentures may be drawn for redemption in part or for redemption in cash and regulations so made shall be valid and binding upon all such Debentureholders notwithstanding the fact that as a result thereof one or more of such Debentures may become subject to redemption in part only or for cash only. In the event that one or more of such Debentures becomes subject to redemption in part only, upon surrender of any such Debentures for payment of the Redemption Price, together with interest accrued to but excluding the Redemption Date, the Issuer shall execute and the Trustee shall certify and deliver without charge to the Debentureholder thereof or upon the Debentureholder’s order one or more new Debentures for the unredeemed part of the principal amount of the Debenture or Debentures so surrendered or, with respect to a Global Debenture, the Depositary shall make notations on the Global Debenture of the principal amount thereof so redeemed. Unless the context otherwise requires, the terms “Debenture” or “Debentures” as used in this Article 4 shall be deemed to mean or include any part of the principal amount of any Debenture which in accordance with the foregoing provisions has become subject to redemption.

4.3 Notice of Redemption

Notice of redemption (the “Redemption Notice”) of any series of Debentures shall be given to the Debentureholders so to be redeemed not more than 60 days nor, subject to section 4.6(b) less than 30 days prior to the date fixed for redemption (the “Redemption Date”) in the manner provided in Section 14.2. Every such notice shall specify the aggregate principal amount of Debentures called for redemption, the Redemption Date, the Redemption Price, the places of payment and shall state that interest upon the principal amount of Debentures called for redemption shall cease to be payable from and after the Redemption Date. In addition, unless all the outstanding Debentures are to be redeemed, the Redemption Notice shall specify:

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

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

(c) in the case of a Global Debenture, that the redemption will take place in such manner as may be agreed upon by the Depositary, the Trustee and the Issuer; and

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

- 34 -

4.7 Failure to Surrender Debentures Called for Redemption

In case the holder of any Debenture so called for redemption shall fail on or before the Redemption Date to so surrender such holder’s Debenture, or shall not within such time accept payment of the Redemption Price payable, or take delivery of certificates representing any Issuer Shares issuable in respect thereof, or give such receipt therefor, if any, as the Trustee may require, such redemption moneys may be set aside in trust (without interest), 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 Debenture shall thereafter

- 38 -

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 of such holder’s Debenture of the Redemption Price plus accrued interest and unpaid interest to the Redemption Date and subsequent distributions on such Issuer Shares, if any, as the case may be.

If an Event of Default has occurred and is continuing, the Issuer may purchase all or any part of the Debentures as aforesaid, except by private contract.

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

- 39 -

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 Depositary shall make notations on the Global Debenture of the principal amount thereof so purchased.

The fact that any such payment is prohibited or any action may not be taken under this Article 5 or under any instrument relating to Senior Indebtedness, shall not prevent the failure to make such payment from being an Event of Default hereunder. Nothing contained in this Article 5 or elsewhere in this Indenture, or in any of the Debentures, shall prevent the conversion of the Debentures or, subject to Sections 5.2 or 5.5 or the application by the Trustee of any moneys deposited with the Trustee hereunder for the purpose, to the payment of or on account of the principal of, or premium, if any, or interest, if any, on the Debentures.

5.8 Knowledge of Trustee

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

5.10 Rights of Holders of Senior Indebtedness Not Impaired

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

5.11 Altering the Senior Indebtedness

The holders of the Senior Indebtedness have the right to extend, renew, modify or amend the terms of the Senior Indebtedness in any manner whatsoever or any security therefor and to release, sell or exchange such security and otherwise to deal freely with the Issuer, all without notice to or consent of the Debentureholders or the Trustee and without affecting the liabilities and obligations of the parties to this Indenture, or the Debentureholders or the Trustee or affecting the rights of the holders of any Senior Indebtedness (or any representative of any such holder) or the Senior Creditors, under this Indenture.

5.12 Additional Indebtedness

This Indenture does not, and shall not, restrict the Issuer from incurring additional Senior Indebtedness at any time or from time to time or other indebtedness or otherwise or mortgaging, pledging or charging its real or personal property or properties to secure any indebtedness or other financing.

5.13 Right of Debentureholder to Convert Not Impaired

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

- 47 -

ARTICLE 6

CONVERSION OF DEBENTURES

6.1 Applicability of Article

Any Debentures issued hereunder of any series which by their terms are convertible (subject, however, to any applicable restriction of the conversion of Debentures of such series) will be convertible into Issuer 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 Issuer 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 Issuer Shares shall be adjusted for in the manner provided in Section 6.6.

6.2 Notice of Expiry of Conversion Privilege

Notice of the expiry of the conversion privileges of the Debentures in all cases other than on the Maturity Date shall be given by or on behalf of the Issuer, not more than 60 days and not less than 30 days prior to the date fixed for the Time of Expiry, in the manner provided in Section 14.2.

6.3 Revival of Right to Convert

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

6.4 Manner of Exercise of Right to Convert

(a) The holder of a Debenture desiring to convert such Debenture in whole or in part into Issuer Shares shall surrender such Debenture to the Trustee at the Designated Office together with the conversion form 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 his executors or administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Trustee, exercising his right to convert such Debenture in accordance with the provisions of this Article;

- 48 -

provided that with respect to a Global Debenture, the obligation to surrender a Debenture to the Trustee shall be satisfied if the Trustee makes notation on the Global Debenture of the principal amount thereof so converted and the Trustee is provided with all other documentation which it may request. Thereupon such Debentureholder or, subject to payment of all applicable stamp or security transfer taxes or other governmental charges and compliance with all reasonable requirements of the Trustee, his nominee(s) or assignee(s), shall be entitled to be entered in the books of the Issuer as at the Date of Conversion (or such later date as is specified in Section 6.4(b)) as the holder of the number of Issuer Shares into which such Debenture is convertible in accordance with the provisions of this Article and, as soon as practicable thereafter, the Issuer shall deliver to such Debentureholder or, subject as aforesaid, his nominee(s) or assignee(s), a certificate or certificates for such Issuer Shares and make or cause to be made any payment of interest to which such Debentureholders is entitled in accordance with Section 6.4(e) hereof.

(b) 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 one of its offices specified in Section 6.4(a); provided that if a Debenture is surrendered for conversion on a day on which the register of Issuer Shares is closed, the Person or Persons entitled to receive Issuer Shares shall become the holder or holders of record of such Issuer Shares as at the date on which such registers are next reopened.

(c) Any part, being $1,000 or such other amount as determined by the Issuer, or an integral multiple thereof as applicable, 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.

(d) Any Debentureholder of which only a part is converted shall, upon the exercise of his or her right of conversion surrender the said Debenture to the Trustee, and the Trustee shall cancel the same and shall without charge forthwith certify and deliver to the Debentureholder a new Debenture or Debentures in an aggregate principal amount equal to the unconverted part of the principal amount of the Debenture so surrendered or, with respect to a Global Debenture, the Trustee shall make notations on the Global Debenture of the principal amount thereof so converted.

(e) The Debentureholder of a Debenture surrendered for conversion in accordance with this Section 6.4 shall be entitled (subject to any applicable restriction or the right to receive interest on conversion of the Debentures of any series) to receive accrued and unpaid interest in respect thereof from and including the last Interest Payment Date, up to but excluding the Date of Conversion of such Debenture and

- 49 -

the Issuer 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 Issuer Shares pursuant to Section 6.4(b), from which applicable date they will for all purposes be and be deemed to be issued and outstanding as fully paid and non-assessable Issuer Shares.

6.5 Adjustment of Conversion Price

The Conversion Price in effect at any date shall be subject to adjustment from time to time as follows:

(a) If and whenever at any time prior to the Time of Expiry the Issuer shall (i) subdivide or redivide the outstanding Issuer Shares into a greater number of shares, (ii) reduce, combine or consolidate the outstanding Issuer Shares into a smaller number of shares, or (iii) issue Issuer Shares or securities convertible into or exchangeable for Issuer Shares to the holders of all or substantially all of the outstanding Issuer Shares by way of a dividend or distribution (other than the issue of Issuer Shares to holders of Issuer Shares who have elected to receive dividends or distributions in the form of Issuer Shares in lieu of cash dividends or cash distributions paid in the ordinary course), 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 Issuer 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 Issuer Shares resulting from such subdivision, redivision, dividend or distribution (including, in the case which securities convertible into or exchangeable for Issuer Shares are distributed, the number of Issuer Shares that would have been outstanding had all such securities been exchanged for or converted into Issuer 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 Issuer Shares resulting from such reduction, combination or consolidation. Such adjustment shall be made successively whenever any event referred to in this Section 6.5(a) shall occur. Any such issue of Issuer 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 Issuer Shares under subsections (b) and (c) of this Section 6.5.

(b) If and whenever at any time prior to the Time of Expiry the Issuer shall fix a record date for the issuance of options, rights or warrants to all or substantially all the holders of its outstanding Issuer Shares entitling them, for a period expiring not more than 45 days after such record date, to subscribe for or purchase Issuer Shares (or securities convertible or exchangeable into Issuer 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 Issuer Share on such record date, the Conversion Price

- 50 -

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 Issuer Shares outstanding on such record date plus a number of Issuer Shares equal to the number arrived at by dividing the aggregate price of the total number of additional Issuer Shares offered for subscription or purchase (or the aggregate conversion or exchange price of the convertible or exchangeable securities so offered) by such Current Market Price per Issuer Share, and of which the denominator shall be the total number of Issuer Shares outstanding on such record date plus the total number of additional Issuer Shares offered for subscription or purchase (or into which the convertible or exchangeable securities so offered are convertible or exchangeable). Such adjustment shall be made successively whenever such a record date is fixed. To the extent that any such options, rights or warrants are not so issued or any such options, rights or warrants are not exercised prior to the expiration thereof, the Conversion Price shall be re-adjusted to the Conversion Price which would then be in effect if such record date had not been fixed or to the Conversion Price which would then be in effect based upon the number of Issuer Shares (or securities convertible or exchangeable into Issuer Shares) actually issued upon the exercise of such options, rights or warrants, as the case may be.

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

- 51 -

Price shall be re-adjusted to the Conversion Price which would then be in effect if such record date had not been fixed or to the Conversion Price which would then be in effect based upon such shares or rights, options or warrants or evidences of indebtedness or assets actually distributed, as the case may be. In clause (iv) of this subsection (c), the term “dividends or distributions paid in the ordinary course” shall include the value of any security or other property or assets distributed in lieu of cash dividends or distributions paid in the ordinary course at the option of the shareholders.

(d) If and whenever at any time prior to the Time of Expiry, there is a reclassification of the Issuer Shares or a capital reorganization of the Issuer other than as described in Section 6.5(a) or a consolidation, amalgamation, arrangement or merger of the Issuer with or into any other Person or other entity; or a sale or conveyance of the property and assets of the Issuer as an entirety or substantially as an entirety to any other Person or other entity or a liquidation, dissolution or winding-up of the Issuer, any Debentureholder 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 Issuer Shares then sought to be acquired by it, the number of shares or other securities or property of the Issuer or of the Person or other entity resulting from such merger, amalgamation, arrangement or consolidation, or to which such sale or conveyance may be made or which holders of Issuer Shares receive pursuant to such liquidation, dissolution or winding-up, as the case may be, that such Debentureholder 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 Issuer Shares sought to be acquired by it and to which it was entitled to acquire upon the exercise of the conversion right. Notwithstanding any other provision of this Section 6.5, if prior to the date that is five years plus one day from the last date of issuance of Debentures pursuant to the short form prospectus of the Issuer dated November 23, 2009, Debentureholders would otherwise be entitled to receive, upon conversion of the Debentures, any property (including cash) or securities that would not constitute “prescribed securities” for the purposes of clause 212(1)(b)(vii)(E) of the Income Tax Act (Canada) as it applied immediately before January 1, 2008 (referred to herein as “Ineligible Consideration”), such Debentureholders shall not be entitled to receive such Ineligible Consideration, but the Issuer or the successor or acquirer, as the case may be, shall have the right (at the sole option of the Issuer or the successor or acquirer, as the case may be) to deliver either such Ineligible Consideration or “prescribed securities” for the purposes of Clause 212(1)(b)(vii)(E) of the Income Tax Act (Canada) as it applied immediately before January 1, 2008 with a market value (as conclusively determined by the Board of Directors) equal to the market

- 52 -

value of such Ineligible Consideration. If determined appropriate by the Board of Directors on behalf of the Issuer to give effect to or to evidence the provisions of this Section 6.5(d), the Issuer, 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 Debentureholder to the end that the provisions set forth in this Indenture shall thereafter correspondingly be made applicable, as nearly as may reasonably be practicable, with respect to any shares or other securities or property to which a Debentureholder is entitled on the exercise of its conversion rights thereafter. Any indenture entered into between the Issuer and the Trustee pursuant to the provisions of this Section 6.5(d) shall be a supplemental indenture entered into pursuant to the provisions of Article 16 hereof. Any indenture entered into between the Issuer, any successor to the Issuer or such purchasing Person or other entity and the Trustee shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided in this Section 6.5(d) and which shall apply to successive reclassifications, capital reorganizations, amalgamations, consolidations, mergers, sales or conveyances or to a liquidation, dissolution or winding-up.

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

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

- 53 -

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

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

(i) In case the Issuer shall take any action affecting the Issuer Shares other than action described in this Section 6.5, which in the opinion of the Board of Directors on behalf of the Issuer 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 Board of Directors on behalf of the Issuer in their sole discretion may determine to be equitable in the circumstances. Failure of the Board of Directors on behalf of the Issuer 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.

(j) 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 Sections 6.5(a), 6.5(b) or 6.5(c) other than the events described in Sections 6.5(a)(i) or 6.5(a)(ii) if the Debentureholders 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.

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

6.6 No Requirement to Issue Fractional Shares

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

- 54 -

6.7 Issuer to Reserve Shares

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

6.8 Cancellation of Converted Debentures

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

6.9 Certificate as to Adjustment

The Issuer shall from time to time immediately after the occurrence of any event which requires an adjustment or readjustment as provided in Section 6.5, deliver an Officer’s Certificate to the Trustee specifying the nature of the event requiring the same and the amount of the adjustment necessitated thereby and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based, which certificate and the amount of the adjustment specified therein shall be verified by an opinion of a firm of chartered accountants appointed by the Issuer and acceptable to the Trustee (who may be the Auditors of the Issuer) and shall be conclusive and binding on all parties in interest. When so approved, the Issuer shall, except in respect of any subdivision, redivision, reduction, combination or consolidation of the Issuer Shares, forthwith give notice to the Debentureholders in the manner provided in Section 14.2 specifying the event requiring such adjustment or readjustment and the results thereof, including the resulting Conversion Price; provided that, if the Issuer has given notice under this Section 6.9 covering all the relevant facts in respect of such event and if the Trustee approves, no such notice need be given under this Section 6.9.

6.10 Notice of Special Matters

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

- 55 -

6.11 Protection of Trustee

Subject to Section 15.3, the Trustee:

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

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

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

(d) shall be entitled to act and rely on the adjustment calculation of the Issuer, the Auditors of the Issuer or investment dealer selected by the Issuer.

6.12 U.S. 1933 Act Legend on Issuer Shares

Each certificate representing Issuer Shares issued upon conversion of Debentures pursuant to this Article 6 bearing the U.S. 1933 Act Legend set forth in Section 2.14, as well as all certificates issued in exchange for or in substitution of the foregoing securities, shall also bear the U.S. 1933 Act Legend set forth in Section 2.14; provided that if the Issuer Shares are being sold outside the United States in accordance with Rule 904 of Regulation S and provided that the Issuer is a “foreign issuer” within the meaning of Regulation S at the time of sale, the U.S. 1933 Act Legend may be removed by providing a declaration to the Trustee, in its capacity as the transfer agent for the Issuer Shares, as set forth in Schedule “E” hereto (or as the Issuer may prescribe from time to time); and provided further that, if any such securities are being sold within the United States in accordance with Rule 144 under the 1933 Act, the U.S. 1933 Act Legend may be removed by delivery to the Trustee in its capacity as the transfer agent for the Issuer Shares, of an opinion of counsel of recognized standing, reasonably satisfactory to the Issuer, to the effect that the U.S. 1933 Act Legend is no longer required under applicable requirements of the 1933 Act or any applicable local laws or regulations. Provided that the Trustee obtains confirmation from the Issuer that such counsel is satisfactory to it, it shall be entitled to rely on such opinion of counsel without further inquiry.

- 56 -

ARTICLE 7

COVENANTS OF THE ISSUER

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

7.1 To Pay Principal and Interest

The Issuer will duly and punctually pay or cause to be paid to every Debentureholder the principal of and interest accrued on the Debentures of which it is the Debentureholder on the dates, at the places and in the manner mentioned herein and in the Debentures subject to the provisions hereof.

7.2 To Pay Trustee’s Remuneration

The Issuer will pay the Trustee reasonable remuneration for its services as Trustee hereunder and will repay to the Trustee on demand all moneys which shall have been paid by the Trustee in connection with the execution of the trusts hereby created and such moneys including the Trustee’s remuneration, shall be payable out of any funds coming into the possession of the Trustee in priority to payment of any principal on any of the Debentures or interest thereon. The said remuneration shall continue to be payable until the trusts hereof be finally wound up and whether or not the trusts of this Indenture shall be in the course of administration by or under the direction of a court of competent jurisdiction.

7.3 To Give Notice of Default

The Issuer shall notify in writing the Trustee immediately upon obtaining knowledge of any Event of Default hereunder.

7.4 Preservation of Existence, etc.

Subject to the express provisions hereof, the Issuer will carry on and conduct its activities, and cause its Subsidiaries to carry on and conduct their businesses, in a proper, efficient and business-like manner and in accordance with good business practices; and, subject to the express provisions hereof, it will do or cause to be done all things necessary to preserve and keep in full force and effect its and its Subsidiaries respective existences and rights.

7.5 Additional Covenants

(a) The Issuer 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 Issuer in accordance with generally accepted accounting principles;

(b) The Issuer 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 Issuer Shares on the TSX, and (ii) maintain its status as a reporting issuer, or the equivalent thereof, not in default of the requirements of Applicable Securities Legislation;

- 57 -

(c) The Issuer shall maintain or cause the related registrar or the related paying agent, as the case may be, to 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 Issuer in respect of such Debentures and this Indenture may be served. The Issuer 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 Issuer 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 principal corporate trust office of the Trustee in Toronto, Ontario and the Issuer hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands;

(d) The Issuer shall deliver to the Trustee within 90 days after the end of each fiscal year of the Issuer and at any reasonable time upon demand by the Trustee, an Officer’s Certificate stating that the Issuer has complied with, in all material respects, all requirements of the Issuer 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; and

(e) The Issuer 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 subsections 4.6(c) and 4.10(c) including, without limitation, make application for any order, ruling, registration or filing or give any notice required under Applicable Securities Legislation.

Notwithstanding that the Issuer may not be required to remain subject to the reporting requirements of the applicable Canadian securities regulatory authority, the Issuer shall provide to the Trustee (a) within 90 days after the end of each fiscal year (or such later date as may be permitted for a reporting issuer by the Ontario Securities Commission), an annual financial statement of the Issuer, and (b) within 45 days after the end of each of the first three fiscal quarters of each fiscal year (or such

- 58 -

later date as may be permitted for a reporting issuer by the Ontario Securities Commission), interim financial statements of the Issuer which shall, at a minimum, contain such information as is required to be provided in quarterly reports under the laws of Canada or any province thereof to security holders of a company with securities listed on the TSX, whether or not the Issuer has any of its securities so listed. Each of such reports will be prepared in accordance with the Canadian disclosure requirements and generally accepted accounting principles.

If the Issuer shall fail to perform any of its covenants contained in this Indenture, and such failure has not been cured or rectified within the time permitted by this Indenture, the Trustee may notify the Debentureholders of such failure on the part of the Issuer or may itself perform any of the covenants capable of being performed by it, but shall be under no obligation to do so or to notify the Debentureholders. All sums so expended or advanced by the Trustee shall be repayable as provided in Section 7.2. No such performance, expenditure or advance by the Trustee shall be deemed to relieve the Issuer of any default hereunder.

If an Event of Default shall occur and be continuing, the Trustee shall, within 30 days after it receives written notice of the occurrence of such Event of Default, give notice of such Event of Default to the Debentureholders in the manner provided in Section 14.2, provided that notwithstanding the foregoing, unless the Trustee shall have been requested to do so by the Debentureholders of at least 25% of the principal amount of the Debentures then outstanding, the Trustee shall not be required to give such notice if the Trustee reasonably and in good faith shall have determined that the withholding of such notice is in the best interests of the Debentureholders and shall have so advised the Issuer in writing.

8.3 Waiver of Default

Upon the happening of any Event of Default hereunder:

(a) the Debentureholders shall have the power (in addition to the powers exercisable by Extraordinary Resolution as hereinafter provided) by requisition in writing by the Debentureholders of 66²/₃% 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 Debentureholder 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 non-observance or non-performance by the Issuer of any covenant applicable only to one or more series of Debentures, then the Debentureholders of not less than 66²/₃% 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 Debentureholders of any other series of Debentures; and

(b) the Trustee, so long as it has not become bound to declare the principal and interest on the Debentures then outstanding to be due and payable, or to obtain or enforce payment of the same, shall have power to waive any Event of Default if, in the Trustee’s 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.

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

- 61 -

8.4 Waiver of Declaration

At any time after a declaration of acceleration with respect to the Debentures has been made pursuant to Section 8.1 and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter provided, the Debentureholders of 66²/₃% of the principal amount of outstanding Debentures, by written notice to the Issuer and the Trustee, may thereupon rescind and annul such declaration and its consequences if the Issuer has paid or deposited with the Trustee a sum sufficient to pay:

(a) all overdue interest on all Debentures;

(b) the principal of (and premium, if any) 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

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

all Events of Default with respect to the Debentures, other than the non-payment of the principal of (and premium, if any), and interest on, such Debentures which have become due solely by such declaration of acceleration, have been cured or waived in accordance with the provisions of this Indenture.

8.5 Enforcement by the Trustee

Subject to the provisions of Sections 5.5, 5.6 and 8.3 and to the provisions of any Extraordinary Resolution that may be passed by the Debentureholders, if the Issuer 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 Debentureholders 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 Debentureholders, or in any one or more of such capacities, but subject in all cases to Section 5.5, 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 Debentureholders allowed in any insolvency, bankruptcy,

- 62 -

liquidation or other judicial proceedings relative to the Issuer or its creditors or relative to or affecting its property. The Trustee is hereby irrevocably appointed (and the successive respective Debentureholders 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 Debentureholders with authority to make and file in the respective names of the Debentureholders or on behalf of the Debentureholders as a class, subject to deduction from any such claims of the amounts of any claims filed by any of the Debentureholders 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 Debentureholders, 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 Debentureholders against the Issuer 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 also have the power at any time and from time to time to institute and to maintain such suits and proceedings as it may be advised shall be necessary or advisable to preserve and protect its interests and the interests of the Debentureholders.

All rights of action hereunder may be enforced by the Trustee without the possession of any of the Debentures or the production thereof on the trial or other proceedings relating thereto. Any such suit or proceeding instituted by the Trustee shall be brought in the name of the Trustee as trustee of an express trust, and any recovery of judgment shall be for the rateable benefit of the Debentureholders 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 Debentureholders, and it shall not be necessary to make any Debentureholders parties to any such proceeding.

8.6 No Suits by Debentureholders

No Debentureholder shall have any right to institute any action, suit or proceeding at law or in equity for the purpose of enforcing payment of the principal of or interest on the Debentures or for the execution of any trust or power hereunder or for the appointment of a liquidator or receiver or for a receiving order under the Bankruptcy and Insolvency Act (Canada) or to have the Issuer wound up or to file or prove a claim in any liquidation or bankruptcy proceeding or for any other remedy hereunder, unless (a) such Debentureholder shall previously have given to the Trustee written notice of the happening (or continuance) of an Event of Default hereunder; (b) the Debentureholders by Extraordinary Resolution or by written instrument signed by the Debentureholders of at least 25% in principal amount of the Debentures then outstanding shall have made a request to the Trustee and the Trustee shall have been afforded reasonable opportunity either itself to proceed to exercise the powers hereinbefore granted or to institute an

- 63 -

action, suit or proceeding in its name for such purpose; (c) the Debentureholders or any of them shall have furnished to the Trustee, when so requested by the Trustee, sufficient funds and security and indemnity satisfactory to it against the costs, expenses and liabilities to be incurred therein or thereby; (d) the Trustee shall have failed to act within 30 days after such notification, request and offer of indemnity and such notification, request and offer of indemnity are hereby declared in every such case, at the option of the Trustee, to be conditions precedent to any such proceeding or for any other remedy hereunder by or on behalf of the Debentureholder; (e) during such 30 day period, the Debentureholders of 66  ²/3% of the principal amount of Debentures do not give the Trustee a direction inconsistent with the request; and (f) such action is not otherwise contrary to Article 5.

8.7 Application of Moneys by Trustee

(a) Except as herein otherwise expressly provided, any moneys received by the Trustee from the Issuer 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 Issuer, shall be applied, together with any other moneys in the hands of the Trustee available for such purpose, as follows:

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

(ii) second, but subject as hereinafter in this Section 8.7 provided, in payment, rateably and proportionately to the Debentureholders, of the principal of and premium (if any) and accrued and unpaid interest and interest on amounts in default on the Debentures which shall then be outstanding in the priority of principal first and then premium and then accrued and unpaid interest and interest on amounts in default unless otherwise directed by Extraordinary Resolution and in that case in such order or priority as between principal, premium (if any) and interest as may be directed by such resolution; and

(iii) third, in payment of the surplus, if any, of such moneys to the Issuer or its assigns;

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

- 64 -

(b) 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 thereout 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 in distribution hereunder.

8.8 Notice of Payment by Trustee

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

8.9 Trustee May Demand Production of Debentures

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

8.10 Remedies Cumulative

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

8.11 Judgement Against the Issuer

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

- 65 -

8.12 Immunity of Directors and Others

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

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

8.15 Delay or Omission Not Waiver

No delay or omission of the Trustee or of any Debentureholder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.

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 Debentureholder shall not invalidate any resolution passed at any such meeting. A Debentureholder may waive notice of a meeting either before or after the meeting.

- 77 -

(b) If the business to be transacted at any meeting by Extraordinary Resolution or otherwise, or any action to be taken or power exercised by instrument in writing under Section 13.15, especially affects the rights of Debentureholders 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 Debentureholders of any other series are affected, determined as provided in Sections 13.2(c) and (d), then:

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

(ii) the Debentureholders 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:

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

(c) Subject to Section 13.2(d), the determination as to whether any business to be transacted at a meeting of Debentureholders, or any action to be taken or power to be exercised by instrument in writing under Section 13.15, especially affects the rights of the Debentureholders of one or more series in a manner or to an extent differing in any material way from that in or to which it affects the rights of Debentureholders of any other series (and is therefore an especially affected series) shall be determined by an opinion of Counsel, which shall be binding on all Debentureholders, the Trustee and the Issuer for all purposes hereof.

(d) A proposal:

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

- 78 -

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

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

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

13.3 Chair

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

At the adjourned meeting, the Debentureholders present in person or by proxy shall, subject to the provisions of Section 13.12, constitute a quorum and may transact the business for which the meeting was originally convened notwithstanding that they may not represent 25% of the principal amount of the outstanding Debentures or of the Debentures then outstanding of each especially affected series. Any business may be brought before or dealt with at an adjourned meeting which might have been brought before or dealt with at the original meeting in accordance with the notice calling the same.

13.6 Show of Hands

Every question submitted to a meeting shall, subject to Section 13.7, be decided in the first place by a majority of the votes given on a show of hands except that votes on Extraordinary Resolutions shall be given in the manner hereinafter provided. At any such meeting, unless a poll is duly demanded as herein provided, a declaration by the chair that a resolution has been carried or carried unanimously or by a particular majority or lost or not carried by a particular majority shall be conclusive evidence of the fact. The chair of any meeting shall be entitled, both on a show of hands and on a poll, to vote in respect of the Debentures, if any, held by him or her.

13.7 Poll

On every Extraordinary Resolution, and on any other question submitted to a meeting when demanded by the chair or by one or more Debentureholders or proxies for Debentureholders, a poll shall be taken in such manner and either at once or after an adjournment as the chair shall direct.

13.8 Voting

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

- 80 -

13.9 Proxies

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

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

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

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

Any regulations so made shall be binding and effective and the votes given in accordance therewith shall be valid and shall be counted. Save as such regulations may provide, the only persons who shall be recognized at any meeting as the holders of any Debentures, or as entitled to vote or be present at the meeting in respect thereof, shall be Debentureholders and persons whom Debentureholders have by instrument in writing duly appointed as their proxies.

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

13.18 Concerning Serial Meetings

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

ARTICLE 15

CONCERNING THE TRUSTEE

15.1 No Conflict of Interest

The Trustee represents to the Issuer that at the date of execution and delivery by it of this Indenture there exists no material conflict of interest in the role of the Trustee as a fiduciary hereunder but if, notwithstanding the provisions of this Section 15.1, such a material conflict of interest exists, or hereafter arises, the validity and enforceability of this Indenture, and the Debentures issued hereunder, shall not be affected in any manner whatsoever by reason only that such material conflict of interest exists or arises but the Trustee shall, within 90 days after ascertaining that it has a material conflict of interest, either eliminate such material conflict of interest or resign in the manner and with the effect specified in Section 15.2.

15.2 Replacement of Trustee

The Trustee may resign its trust and be discharged from all further duties and liabilities hereunder by giving to the Issuer two months notice in writing or such shorter notice as the Issuer may accept as sufficient. The Issuer shall have the power, at any time, on reasonable notice in writing to the Trustee and the Debentureholders shall have the power by Extraordinary Resolution, at any time, to remove the existing Trustee and appoint a new or successor Trustee. If at any time a material conflict of interest exists in the Trustee’s role as a fiduciary hereunder the Trustee shall, within 90 days after ascertaining that such a material conflict of interest exists, either eliminate such material conflict of interest or resign in the manner and with the effect specified in this Section 15.2. The validity and enforceability of this Indenture and of the Debentures issued hereunder shall not be affected in any manner whatsoever by reason only that such a material conflict of interest exists. In the event of the Trustee resigning or being removed or being dissolved, becoming bankrupt, going into liquidation or otherwise becoming incapable of acting hereunder, the Issuer shall forthwith appoint a new Trustee unless a new Trustee has already been appointed by the Debentureholders. Failing such appointment by the Issuer, the retiring Trustee or any Debentureholder may apply to a Judge of the Ontario Superior Court of Justice, on such notice as such Judge may direct at the Issuer’s expense, for the appointment of a new Trustee but any new Trustee so appointed by the Issuer or by such court shall be subject to removal as aforesaid by the Debentureholders and the appointment of such new Trustee shall be effective only upon such new Trustee becoming bound by this Indenture. Any new Trustee appointed under any provision of this Section 15.2 shall be a corporation authorized to carry on the business of a trust company in all of the Provinces of Canada. On any new appointment the new Trustee shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Trustee.

Any company into which the Trustee may be merged or with which it may be consolidated or amalgamated or any company resulting from any merger, consolidation or amalgamation to which the Trustee shall be a party, shall be the successor Trustee under this Indenture without the execution of any instrument or any further act. Nevertheless, upon the written request of the successor Trustee or of the Issuer, the Trustee ceasing to act shall execute and deliver an instrument assigning and transferring to such successor Trustee, upon the trusts

- 88 -

herein expressed, all the rights, powers and trusts of the Trustee so ceasing to act, and shall duly assign, transfer and deliver all property and money held by such Trustee to the successor Trustee so appointed in its place. Should any deed, conveyance or instrument in writing from the Issuer be required by any new Trustee or more fully and certainly vesting in and confirming to it such estates, properties, rights, powers and trusts, then any and all such deeds, conveyances and instruments in writing shall on request of said new Trustee, be made, executed, acknowledged and delivered by the Issuer.

15.3 Duties of Trustee

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

15.4 Reliance Upon Declarations, Opinions, etc.

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

15.5 Evidence and Authority to Trustee, Opinions, etc.

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

Such evidence shall consist of:

(a) a certificate made by any one officer or director of the Issuer stating that any such condition precedent has been complied with in accordance with the terms of this Indenture;

- 89 -

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

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

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

Each statutory declaration, certificate, opinion or report with respect to compliance with a condition precedent provided for in this Indenture shall include (a) a statement by the person giving the evidence that he has read and is familiar with those provisions of this Indenture relating to the condition precedent in question, (b) a brief statement of the nature and scope of the examination or investigation upon which the statements or opinions contained in such evidence are based, (c) a statement that, in the belief of the person giving such evidence, the person has made such examination or investigation as is necessary to enable him or her to make the statements or give the opinions contained or expressed therein, (d) a statement whether in the opinion of such person the conditions precedent in question have been complied with or satisfied, and (e) a statement that no default or Event of Default has occurred or will occur by reason of the action taken.

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

15.6 Officer’s Certificates Evidence

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

- 90 -

15.7 Experts, Advisers and Agents

The Trustee may:

(a) employ or retain and act and rely on the opinion or advice of or information obtained from any solicitor, auditor, valuer, engineer, surveyor, appraiser or other expert, whether obtained by the Trustee or by the Issuer, or otherwise, and shall not be liable for acting, or refusing to act, in good faith on any such opinion or advice and may pay proper and reasonable compensation for all such legal and other advice or assistance as aforesaid; and

(b) employ such agents and other assistants as it may reasonably require for the proper determination and discharge of its duties hereunder, and may pay reasonable remuneration for all services performed for it (and shall be entitled to receive reasonable remuneration for all services performed by it) in the discharge of the trusts hereof and compensation for all disbursements, costs and expenses made or incurred by it in the discharge of its duties hereunder and in the management of the trusts hereof any solicitors employed or consulted by the Trustee may, but need not be, solicitors for the Issuer.

15.8 Trustee May Deal in Debentures

Subject to Sections 15.1 and 15.3, the Trustee may, in its personal or other capacity, buy, sell, lend upon and deal in the Debentures and generally contract and enter into financial transactions with the Issuer or otherwise, without being liable to account for any profits made thereby.

15.9 Investment of Moneys Held by Trustee

Upon receipt of a written direction from the Issuer, the Trustee shall invest the funds in its name in accordance with such direction. Any direction from the Issuer to the Trustee shall be in writing and shall be provided to the Trustee no later than 9:00 a.m. on the day on which the investment is to be made. Any such direction received by the Trustee after 9:00 a.m. or received on a non-Business Day, shall be deemed to have been given prior to 9:00 a.m. the next Business Day. For the purpose hereof, “Authorized Investments” means short term interest bearing or discount debt obligations issued or guaranteed by the Government of Canada or a Province or a Canadian chartered bank (which may include an Affiliate or related party of the Trustee) provided that such obligation is rated at least R1 (middle) by DBRS, Inc. or an equivalent rating service.

In addition to any written direction to invest cash in an Authorized Investment, the Trustee may hold cash balances constituting part or all of the Issuer and may, but need not, invest same in its deposit department or the deposit department of one of its Affiliates; but the

- 91 -

Trustee and its Affiliates shall not be liable to account for any profit to any parties to this Agreement or to any other Person or entity other than at a rate, if any, established from time to time by the Trustee or one of its Affiliates. For the purpose of this Section “Affiliate” means affiliated companies within the meaning of the Business Corporations Act (Ontario) (“OBCA”); and includes Canadian Imperial Bank of Commerce, CIBC Mellon Global Securities Services Company and The Bank of New York Mellon and each of their affiliates within the meaning of the OBCA.

The Trustee shall not be held liable for any losses incurred in the investment of any funds in Authorized Investments.

Unless and until the Trustee shall have declared the principal of and interest on the Debentures to be due and payable, the Trustee shall pay over to the Issuer all interest received by the Trustee in respect of any Investments or deposits made pursuant to the provisions of this Section.

15.10 Trustee Not Ordinarily Bound

Except as provided in Section 8.2 and as otherwise specifically provided herein, the Trustee shall not, subject to Section 15.3, be bound to give notice to any Person of the execution hereof, nor to do, observe or perform or see to the observance or performance by the Issuer of any of the obligations herein imposed upon the Issuer or of the covenants on the part of the Issuer herein contained, nor in any way to supervise or interfere with the conduct of the Issuer’s business, unless the Trustee shall have been required to do so in writing by the Debentureholders of not less than 25% of the aggregate principal amount of the Debentures then outstanding or by any Extraordinary Resolution of the Debentureholders passed in accordance with the provisions contained in Article 13, and then only after it shall have been funded and indemnified to its satisfaction against all actions, proceedings, claims and demands to which it may render itself liable and all costs, charges, damages and expenses which it may incur by so doing.

15.11 Trustee Not Required to Give Security

The Trustee shall not be required to give any bond or security in respect of the execution of the trusts and powers of this Indenture or otherwise in respect of the premises.

15.12 Trustee Not Bound to Act on Issuer’s Request

Except as in this Indenture otherwise specifically provided, the Trustee shall not be bound to act in accordance with any direction or request of the Issuer or of the trustees until a duly authenticated copy of the instrument or resolution containing such direction or request shall have been delivered to the Trustee, and the Trustee shall be empowered to act upon any such copy purporting to be authenticated and believed by the Trustee to be genuine.

- 92 -

15.13 Conditions Precedent to Trustee’s Obligations to Act Hereunder

The obligation of the Trustee to commence or continue any act, action or proceeding for the purpose of enforcing the rights of the Trustee and of the Debentureholders hereunder shall be conditional upon the Debentureholders furnishing when required by notice in writing by the Trustee, sufficient funds to commence or continue such act, action or proceeding and indemnity reasonably satisfactory to the Trustee to protect and hold harmless the Trustee against the costs, charges and expenses and liabilities to be incurred thereby and any loss and damage it may suffer by reason thereof.

The Trustee shall not be bound to give any notice or do or take any act, action or proceeding by virtue of the powers conferred on it hereby unless and until it shall have been required so to do under the terms hereof; nor shall the Trustee be required to take notice of any default hereunder, unless and until notified in writing of such default, which notice shall distinctly specify the default desired to be brought to the attention of the Trustee and in the absence of any such notice the Trustee may for all purposes of this Indenture conclusively assume that no default has been made in the observance or performance of any of the representations, warranties, covenants, agreements or conditions contained herein. Any such notice shall in no way limit any discretion herein given the Trustee to determine whether or not the Trustee shall take action with respect to any default.

None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties or in the exercise of any of its rights or powers unless indemnified as aforesaid.

The Trustee may, before commencing or at any time during the continuance of any such act, action or proceeding require the Debentureholders at whose instance it is acting to deposit with the Trustee the Debentures held by them for which Debentures the Trustee shall issue receipts.

15.14 Authority to Carry on Business

The Trustee represents to the Issuer that at the date of execution and delivery by it of this Indenture it is authorized to carry on the business of a trust company in each of the Provinces of Canada but if, notwithstanding the provisions of this Section 15.14, it ceases to be so authorized to carry on business, the validity and enforceability of this Indenture and the securities issued hereunder shall not be affected in any manner whatsoever by reason only of such event but the Trustee shall, within 90 days after ceasing to be authorized to carry on the business of trust company in any of the Provinces of Canada either become so authorized or resign in the manner and with the effect specified in Section 15.2.

15.15 Compensation and Indemnity

(a) The Issuer shall pay to the Trustee from time to time compensation for its services hereunder as agreed separately by the Issuer and the Trustee, and shall pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements

- 93 -

and advances incurred or made by the Trustee in the administration or execution of its duties under this Indenture (including the reasonable and documented compensation and disbursements of its counsel and all other advisers and assistants not regularly in its employ), both before any default hereunder and thereafter until all duties of the Trustee under this Indenture shall be finally and fully performed. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust.

(b) The Issuer hereby indemnifies and saves harmless the Trustee and its directors, officers and employees from and against any and all losses, damages, charges, expenses, claims, demands, actions or liability whatsoever which may be brought against the Trustee or which it may suffer or incur as a result of or arising out of the performance of its duties and obligations hereunder save only in the event of the gross negligent failure to act, or the wilful misconduct or bad faith of the Trustee. This indemnity will survive the termination or discharge of this Indenture and the resignation or removal of the Trustee. The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. The Issuer shall defend the claim and the Trustee shall co-operate in the defence. The Trustee may have separate counsel and the Issuer shall pay the reasonable fees and expenses of such counsel. The Issuer need not pay for any settlement made without its consent, which consent must not be unreasonably withheld. This indemnity shall survive the resignation or removal of the Trustee or the discharge of this Indenture.

(c) The Issuer need not reimburse any expense or indemnify against any loss or liability incurred by the Trustee through gross negligence or bad faith or reckless disregard of the Trustee’s duties hereunder.

15.16 Acceptance of Issuer

The Trustee hereby accepts the trusts in this Indenture declared and provided for and agrees to perform the same upon the terms and conditions herein set forth and to hold all rights, privileges and benefits conferred hereby and by law in trust for the various Persons who shall from time to time be Debentureholders, subject to all the terms and conditions herein set forth.

The parties hereto acknowledge and agree, and any beneficiaries hereunder are hereby deemed to have acknowledged and agreed that the Trustee may, without the consent of any other party, assign all of its rights and duties under this Indenture, and under any ancillary agreements executed in connection herewith, to such federal trust company as may result from CIBC Mellon Trust Company being continued as a trust company pursuant to the terms of the Trust and Loan Companies Act (Canada). Any such assignment shall be effective without the need for any further notice or advice to, or approval of, the parties hereto and without any further act or formality whatsoever.

ALGONQUIN POWER & UTILITIES CORP. (the “Issuer”) for value received hereby acknowledges itself indebted and, subject to the provisions of the Trust Indenture (the “Indenture”) dated as of December 2, 2009 between the Issuer and CIBC Mellon Trust Company (the “Trustee”), promises to pay to the registered Debentureholder hereof on June 30, 2017 (the “Maturity Date”) or on such earlier date as the principal amount hereof may become due in accordance with the provisions of the indenture the principal sum of                                                                                                                                             DOLLARS in lawful money of Canada on presentation and surrender of this Series 3A Debenture at the main branch of the Trustee in Xxxxxxx, Xxxxxxx, in accordance with the terms of the Indenture and, subject as hereinafter provided, to pay interest on the principal amount hereof from the date hereof, or from the last Interest Payment Date to which interest shall have been paid or made available for payment hereon, whichever is later, at the rate of 7% per annum, in like money in arrears in equal semi-annual installments (less any tax required by law to be deducted) on June 30 and December 31 in each year, except the first such payment to fall due on June 30, 2010 shall be in the amount of $40.75 per $1,000 principal amount of Series 3A Debentures and, should the Issuer at any time make default in the payment of any principal or Interest, to pay interest on the amount in default at the same rate, in like money and on the same dates.

Interest hereon shall be payable by cheque or by electronic transfer of funds transferred to the registered Debentureholder hereof and, subject to the provisions of the Indenture, the mailing of such cheque or electronic transfer of funds, as the case may be, shall, to the extent of the sum represented thereby (plus the amount of any tax withheld), satisfy and discharge all liability for interest on this Series 3A Debenture.

This Debenture is one of the Debentures of the Issuer issued or issuable in one or more series under the provisions of the Indenture (individually a “Series 3A Debenture” and collectively the “Series 3A Debentures”). However, subject to the terms of the Indenture, additional debentures may be issued pursuant to the Indenture after the date hereof. The Series 3A Debentures are limited to an aggregate principal amount of $63,250,000 in lawful money of Canada. Reference is hereby expressly made to the Indenture for a description of the terms and conditions upon which the Series 3A Debentures are or are to be issued and held and the rights and remedies of the Debentureholders of the Series 3A Debentures and of the Issuer and of the Trustee, all to the same effect as if the provisions of the Indenture were herein set forth to all of which provisions the Debentureholder of this Series 3A Debenture by acceptance hereof assents.

The Series 3A Debentures are issuable only in denominations of $1,000 and integral multiples thereof. Upon compliance with the provisions of the Indenture, Series 3A Debentures of any denomination may be exchanged for an equal aggregate principal amount of Series 3A Debentures in any other authorized denomination or denominations.

The whole, or if this Series 3A Debenture is in a denomination in excess of $1,000 any part of which is $1,000 or an integral multiple thereof, of the principal of this Series 3A Debenture is convertible, at the option of the Debentureholder hereof, upon surrender of this Series 3A Debenture at the principal office of the Trustee in the City of Xxxxxxx, Xxxxxxx, at any time prior to the close of business on the Maturity Date or, if this Series 3A Debenture is called for redemption on or prior to such date, then at any time, but not after the close of business on the last Business Day immediately preceding the date specified for redemption of this Series 3A Debenture, into Issuer Shares (without adjustment for dividends or distributions on Issuer Shares issuable upon conversion) at a conversion price of $4.20 (the “Conversion Price”) per Issuer Share, being a rate of 238.1 Issuer Shares for each $1,000 principal amount of Series 3A Debentures, all subject to the terms and conditions and in the manner set forth in the Indenture. The Indenture makes provision for the adjustment of the Conversion Price in the events therein specified. No fractional Issuer Shares will be issued on any conversion but in lieu thereof, the Issuer will satisfy such fractional interest by a cash payment equal to the market price of such fractional interest as determined in accordance with the Indenture.

The Series 3A Debenture may be redeemed at the option of the Issuer on the terms and conditions set out in the Indenture at the redemption price therein set out. This Series 3A Debenture is not redeemable on or before December 31, 2012, except in the event of the satisfaction of certain conditions after a Change of Control has occurred. After December 31, 2012, and on or prior to December 31, 2014, this Series 3A Debenture is redeemable at the option of the Issuer in whole or in part at a price equal to the principal amount of the Series 3A Debentures (the “Redemption Price”) provided that the Issuer files with the Trustee on the date that notice of redemption of this Series 3A Debenture is first provided, an Officer’s Certificate of the Issuer certifying that the weighted average price of the Issuer Shares on the TSX (or elsewhere in accordance with the Indenture) for 20 consecutive trading days, ending on the fifth trading day preceding the date notice is given (the “Current Market Price”), is at least 125% of the Conversion Price then in effect and otherwise on the terms and conditions described in the Indenture.

be required to make an offer to purchase the whole or, at the option of the Debentureholder, any part of such Debentureholder’s Series 3A Debentures at a price equal to 101% of the principal amount of such Series 3A Debentures plus accrued and unpaid interest, if any, up to, but excluding, the date the Series 3A Debentures are so purchased. The Issuer, at its option, may elect to satisfy the principal portion of such purchase price either by payment in cash or by the issuance of Issuer Shares to the Debentureholder. If holders of 90% or more of the aggregate principal amount of all Series 3A Debentures outstanding on the date the Issuer delivers the Change of Control Notice to the Trustee accept the Change of Control Offer, the Issuer shall have the right to redeem all the remaining outstanding Series 3A Debentures on the same date and at the same price.

If a takeover bid for Series 3A Debentures, within the meaning of the Securities Act (Ontario) is made and 90% or more of the principal amount of all the Series 3A Debentures (other than Series 3A Debentures held at the date of the takeover bid by or on behalf of the Offeror, Associates or Affiliates of the Offeror or anyone acting jointly or in concert with the Offeror) are taken up and paid for by the Offeror, the Offeror will be entitled to acquire the Series 3A Debentures of those Debentureholders who did not accept the offer on the same terms as the Offeror acquired the first 90% of the principal amount of the Series 3A Debentures.

The Issuer may, on notice as provided in the Indenture, at its option and (subject to any applicable regulatory approval), elect to satisfy the obligation to repay all or any portion of the principal amount of this Series 3A Debenture on the Maturity Date or on redemption by the issue of that number of Freely Tradable Issuer Shares obtained by dividing that portion of the principal amount of this Series 3A Debenture that the Issuer elects to satisfy by the issue of Freely Tradable Issuer Shares by 95% of the Current Market Price on the Maturity Date or the date fixed for redemption, as the case may be.

The indebtedness evidenced by this Series 3A Debenture, and by all other Series 3A Debentures now or hereafter certified and delivered under the Indenture, is a direct unsecured obligation of the Issuer, and is subordinated in right of payment, to the extent and in the manner provided in the Indenture, to the prior payment of all Senior Indebtedness, including any indebtedness to trade creditors, whether outstanding at the date of the Indenture or thereafter created, incurred, assumed or guaranteed.

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

The Indenture contains provisions making binding upon all Debentureholders of Debentures outstanding thereunder (or in certain circumstances, specific series of Debentures) resolutions passed at meetings of such Debentureholders held in accordance with such provisions and instruments signed by the Debentureholders of a specified majority of Debentures outstanding (or specific series), which resolutions or instruments may have the effect of amending the terms of this Series 3A Debenture or the Indenture.

The Indenture contains provisions disclaiming any personal liability on the part of holders of Issuer Shares, the directors, officers or agents of the Issuer in respect of any obligation or claim arising out of the Indenture or this Series 3A Debenture and limiting recourse against the Issuer to the property of the Issuer.
