any other terms of the Debentures of the series (which terms shall not be inconsistent with the provisions of this Indenture).

All Debentures of any one series shall be substantially identical, except as may otherwise be established herein or by or pursuant to a resolution of the Directors, Certificate of the Company or in an indenture supplemental hereto. All Debentures of any one series need not be issued at the same time and may be issued from time to time, including pursuant to a Periodic Offering, consistent with the terms of this Indenture, if so provided herein, by or pursuant to such resolution of the Directors, Certificate of the Company or in an indenture supplemental hereto.

2.3

Form of Debentures

Except in respect of the Initial Debentures, the form of which is provided for herein, the Debentures of each series shall be substantially in such form or forms (not inconsistent with this Indenture) as shall be established herein or by or pursuant to one or more resolutions of the Directors (as set forth in a resolution of the Directors or to the extent established pursuant to, rather than set forth in, a resolution of the Directors, in a Certificate of the Company detailing such establishment) or in one or more indentures supplemental hereto, in each case with such appropriate insertions, omissions, substitutions and other variations as are 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 to general usage, all as may be determined by the Director or officer executing such Debentures, as conclusively evidenced by his or her execution of such Debentures.

2.4

Form and Terms of Initial Debentures

(a)

The first series of Debentures (the “Initial Debentures”) authorized for issue immediately is unlimited in aggregate principal amount and shall be designated as “Unsecured Subordinated Floating Rate Debentures, Series 1”.

(b)

The Initial Debentures shall be dated as of the First Issue Date, shall mature on the Initial Debenture Maturity Date and shall bear interest from, and including, the First Issue Date to, but excluding, March 31, 2015 at the rate of 7.4% per annum. From and including March 31, 2015 to but excluding the Initial Debenture Maturity Date, the interest rate applicable to the Debentures will be reset on an annual basis on March 31 of each year, at a rate equal to the Cost of Living Adjustment (which amount may be positive or negative) plus 6.5% (“Floating Interest”). Notwithstanding the foregoing, the interest rate applicable to the Debentures will at no time be less than 0%. Interest will be payable quarterly in arrears in equal instalments on March 31, June 30, September 30 and December 31 in each year, commencing on December 31, 2014 and the last such payment (representing interest payable from the last Interest Payment Date to, but excluding, the Initial Debenture Maturity Date or the earlier date of redemption of the Initial Debentures), subject as hereinafter provided, to fall due on the Initial Debenture Maturity Date or the earlier date of redemption, payable after as well

as before maturity and after as well as before default, with interest on amounts in default at the same rate, compounded semi-annually. For certainty, the first interest payment will include interest accrued from and including the First Issue Date to, but excluding, December 31, 2014 in the amount of $1.8449 for each $100 principal amount of Debentures outstanding.

(c)

The Initial Debentures will be redeemable at the option of the Company in accordance with the terms of Article 4, provided that the Initial Debentures will not be redeemable prior to March 31, 2020, except in the event of the satisfaction of certain conditions after a Change of Control has occurred as outlined herein.

During the period beginning on March 16 and ending on March 31 of each year, the Company will have the right, at its option, to give notice to holders of Initial Debentures of its intention to redeem the Initial Debentures, in whole or in part, on March 31 in the year that is five years following the year in which notice is given, at a price equal to the principal amount thereof plus accrued and unpaid interest up to but excluding the Redemption Call Date.

In the event the Company exercises its right to redeem some or all of the outstanding Initial Debentures in a given year, the Company will send a reminder redemption notice to holders of Initial Debentures not less than 30 nor more than 60 days prior to each applicable Redemption Call Date. The Redemption Call Notice for the Initial Debentures shall be substantially in the form of Schedule B.

(d)

The Initial Debentures will be redeemable at the option of each Debentureholder in accordance with the terms of Article 5, provided that the Initial Debentures will not be redeemable prior to March 31, 2020, except in the event of the satisfaction of certain conditions after a Change of Control has occurred as outlined herein.

During the period beginning on March 1 and ending on March 15 of each year, holders of Initial Debentures will have the right, at their option, to give notice to the Company of their intention to require the Company to repurchase (or to “put”) the Initial Debentures, in whole or in part, on March 31 in the year that is five years following the year in which notice is given, at a price equal to the principal amount thereof plus accrued and unpaid interest up to but excluding the Redemption Put Date.

A holder of Debentures who has exercised its put right in respect of some or all of the Initial Debentures held by such holder will be required to deposit such Initial Debentures with the Trustee to be held in escrow by the Trustee until the applicable Redemption Put Date and will no longer be transferable over the facilities of the TSX or otherwise. The Redemption Put Notice for the Initial Debentures shall be substantially in the form of Schedule C.

(e)

The Initial Debentures, including the payment of the principal thereof and interest thereon, will be subordinated to the prior payment in full of all Senior Indebtedness in accordance with the provisions of Article 6.

(f)

The Initial Debentures shall be issued as Registered Debentures in denominations of $100 and integral multiples of $100. Each Initial Debenture and the certificate of the Debenture Trustee endorsed thereon shall be issued in substantially the form set out in Schedule A, with such insertions, omissions, substitutions or other variations as shall be required or permitted by this Indenture, and may have imprinted or otherwise reproduced thereon such legend or legends or endorsements, not inconsistent with the provisions of this Indenture, as may be required to comply with any law or with any rules or regulations pursuant thereto or with any rules or regulations of any securities exchange or securities regulatory authority or to conform with general usage, all as may be determined by the Director or officer 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 Debenture Trustee shall approve. Notwithstanding the foregoing, an Initial Debenture may be in such other form or forms as may, from time to time, be approved by a resolution of the Directors or as specified in a Certificate of the Company. 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 CDS. The Global Debentures will be registered in the name of the Depository (or any nominee of the Depository). No beneficial holder will receive definitive certificates representing their interest in Initial Debentures except as provided in Section 3.2. A Global Debenture may be exchanged for Initial 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.

(g)

Within 30 days following the occurrence of a Change of Control, the Company shall be obligated to offer to purchase all Initial Debentures then outstanding. The terms and conditions of such obligation are set forth below:

(i)

Within 30 days following the consummation of a Change of Control, the Company shall deliver to the Debenture Trustee a notice in writing stating that there has been a Change of Control and specifying the date on which such Change of Control occurred and the circumstances or events giving rise to such Change of Control together with a cash offer in writing (the “Offer to Purchase”) to purchase all of the Initial Debentures then outstanding from the holders thereof at a price per Initial Debenture equal to 100% of the principal amount thereof together with accrued and unpaid interest thereon up to but excluding the Change of Control Purchase Date (as defined below) (the “Offer Price”). The Debenture Trustee will promptly thereafter deliver, by prepaid courier or mail, the Offer to Purchase to the holders of all Initial Debentures then outstanding, at their addresses appearing in the registers of holders of Initial Debentures maintained by the Debenture Trustee.

(ii)

The Offer to Purchase shall specify the date (the “Expiry Date”) and time (the “Expiry Time”) on which the Offer to Purchase shall expire, which date and time shall not, unless otherwise required by Applicable Securities Legislation, be earlier than the close of business on the 35th day and not later than the close of business on the 60th day following the date on which such Offer to Purchase is delivered or mailed by or on behalf of the Debenture Trustee as provided above.

(iii)

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

(iv)

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

(v)

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

(vi)

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

(vii)

If holders of 90% or more of the aggregate principal amount of Initial Debentures outstanding on the date the Company delivers the Offer to Purchase to the Debenture Trustee (other than Initial Debentures held at the date of the takeover bid by or on behalf of the Offeror, Affiliates or Associates (as such terms are defined in Section 1.1 or Section 11.1 of this Indenture) of the Offeror or anyone acting jointly or in concert with the Offeror, within the meaning of Section 11.1) accept the Offer to Purchase, the Company shall have the right (the “90% Redemption Right”), upon written notice (the “90% Redemption Right Notice”) provided to the Debenture Trustee within 10 days following the Expiry Date, to elect to redeem all the Initial Debentures remaining outstanding at the Offer Price

and on the other terms and conditions provided herein. Upon receipt of such notice by the Debenture Trustee, the Debenture Trustee shall promptly provide written notice to each holder of outstanding Initial Debentures (other than those that have accepted the Offer to Purchase) that:

(A)

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

(B)

such holder must surrender its Initial Debentures to the Debenture Trustee within 10 days after the sending of such notice; provided that with respect to a Global Debenture, the obligation to surrender an Initial Debenture to the Debenture Trustee shall be satisfied if the Debenture Trustee makes a notation on the Global Debenture of the principal amount thereof so transferred; and

(C)

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

(viii)

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

(ix)

The Initial Debentures in respect of which the Company has made payment to the Debenture Trustee in accordance with the terms of this Section 2.4(g) (or the portion thereof tendered in acceptance of the Offer to Purchase) shall thereafter no longer be considered to be outstanding under this Indenture. The Company shall also deposit with the Debenture Trustee a sum of money sufficient to pay any charges or expenses which

may be incurred by the Debenture Trustee in connection with the Offer to Purchase and the exercise of the 90% Redemption Right if applicable. All Initial Debentures in respect of which payment of the Offer Price has been so made shall be cancelled by the Debenture Trustee.

(x)

In the event a portion of the principal amount only of an Initial Debenture is tendered by a holder thereof in acceptance of the Offer to Purchase, the Company shall execute and deliver to the Debenture Trustee and the Debenture Trustee shall certify and deliver to the holder, without charge to such holder, a certificate representing the principal amount of the Initial Debenture not so tendered in acceptance of the Offer to Purchase.

(xi)

In connection with an Offer to Purchase, the Company shall comply with all applicable U.S. securities laws, including, without limitation, Regulation 14E under the 1934 Act and all laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the Offer to Purchase. To the extent the provisions of any such laws or rules conflict with the provisions of this Indenture relating to the Offer to Purchase, the Company shall comply with the provisions of such laws or rules and be deemed not to have breached its obligations contained in this Indenture relating to such Offer to Purchase by virtue of such compliance.

(h)

Any unpaid interest in respect of the Initial Debentures that the Company fails to pay to the holders of Initial Debentures on an interest payment date will form part of the principal amount of such Initial Debentures (the “New Principal Amount”) and will be subject to interest in accordance with the terms of the Initial Debentures. The New Principal Amount will be due and payable on the occurrence of any event giving rise to the obligation of the Company to pay or cause the payment of the redemption price, as the case may be, as part of such price and not prior thereto.

(i)

If, on any interest payment date, the Company fails to pay the interest on the Initial Debentures in full, the Company will not (i) declare dividends of any kind on the Common Shares, nor (ii) participate in any share buyback or redemption involving the Common Shares, until the Company first pays such interest (or the unpaid portion thereof) to holders of Initial Debentures.

(j)

The Debenture 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 Company may from time to time request the Debenture Trustee to certify and deliver Additional Debentures of any series by delivering to the Debenture Trustee the documents referred to below in this Section 2.5 whereupon the Debenture Trustee shall certify such

Debentures and cause the same to be delivered in accordance with the Written Direction of the Company referred to below or pursuant to such procedures acceptable to the Debenture Trustee as may be specified from time to time by a Written Direction of the Company. 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 or determined by or pursuant to such Written Direction of the Company and procedures. In certifying such Additional Debentures, the Debenture Trustee shall be entitled to receive and shall be fully protected in relying upon, unless and until such documents have been superseded or revoked:

(a)

a Certificate of the Company and/or executed supplemental indenture by or pursuant to which the form and terms of such Additional Debentures were established;

(b)

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

(i)

such Written Direction of the Company may be delivered by the Company to the Debenture Trustee prior to the delivery to the Debenture Trustee of such Additional Debentures of such series for certification and delivery;

(ii)

the Debenture 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 Company or pursuant to procedures acceptable to the Debenture Trustee as may be specified from time to time by a Written Direction of the Company;

(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 Company or pursuant to such procedures; and

(iv)

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

(c)

an opinion of Counsel, in form and substance satisfactory to the Debenture Trustee, acting reasonably, to the effect 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

(d)

a Certificate of the Company certifying that the Company is not in default under this Indenture, that the terms and conditions for the certification and delivery of Additional Debentures (including those set forth in Section 13.5), have been complied with subject to the delivery of any documents or instruments specified

in such Certificate of the Company and that no Event of Default exists or will exist upon such certification and delivery.

2.6

Issue of Global Debentures

(a)

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

(ii)

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

(iii)

bear a legend substantially to the following effect if the Depository is CDS:

“UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF CDS CLEARING AND DEPOSITORY SERVICES INC. (“CDS”) TO CONSTELLATION SOFTWARE INC. (THE “ISSUER”) OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IN RESPECT THEREOF IS REGISTERED IN THE NAME OF CDS & CO., OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS (AND ANY PAYMENT IS MADE TO CDS & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED HOLDER HEREOF, CDS & CO., HAS A PROPERTY INTEREST IN THE SECURITIES REPRESENTED BY THIS CERTIFICATE HEREIN AND IT IS A VIOLATION OF ITS RIGHTS FOR ANOTHER PERSON TO HOLD, TRANSFER OR DEAL WITH THIS CERTIFICATE.”

(b)

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

2.7

Execution of Debentures

All Debentures shall be signed (either manually or by facsimile or other electronic signature howsoever delivered) by any one Director or officer of the Company. A facsimile or other electronic signature upon a Debenture shall for all purposes of this Indenture be deemed to be the signature of the person whose signature it purports to be. Notwithstanding that any person whose signature, either manual or in facsimile or by electronic mail, appears on a Debenture as Director or officer of the Company 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 Company 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 holder to the benefits of this Indenture, until it has been manually certified by or on behalf of the Debenture Trustee substantially in the form set out in this Indenture, in the relevant supplemental indenture, or in some other form approved by the Debenture Trustee. Such certification on any Debenture shall be conclusive evidence that such Debenture is duly issued, is a valid obligation of the Company and the holder is entitled to the benefits hereof.

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

2.9

Mutilation, Loss, Theft or Destruction

In case any of the Debentures issued hereunder shall become mutilated or be lost, stolen or destroyed and in the absence of notice that such Debenture has been acquired by a bona fide purchaser, the Company, in its discretion, may issue, and thereupon the Debenture 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 Debenture 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. The new or substituted Debenture may have endorsed upon it the fact that it is in replacement of a previous Debenture. In case of loss, theft or destruction the applicant for a substituted Debenture shall furnish to the Company and to the Debenture Trustee such evidence of the loss, theft or destruction of the Debenture and such other documents as shall be satisfactory to them in their discretion and shall also furnish an indemnity and surety bond satisfactory to them in their discretion. The applicant shall pay all reasonable expenses incidental to the issuance of any substituted Debenture.

2.10

Concerning Interest

(a)

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

(b)

Unless otherwise specifically provided in the terms of the Debentures of any series, interest for any period of less than three 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.

2.11

Debentures to Rank Pari Passu

The Debentures will be direct, subordinated unsecured obligations of the Company. Each Debenture will rank pari passu with each other Debenture (regardless of their actual date or terms of issue) and, subject to statutory preferred exceptions, with all other present and future subordinated and unsecured indebtedness of the Company (other than Senior Indebtedness) except for sinking fund provisions (if any) applicable to different series of Debentures or other similar types of obligations of the Company.

2.12

Payments of Amounts Due on Maturity

Except as may otherwise be provided in this Indenture and any supplemental indenture in respect of any series of Debentures, payments of amounts due upon maturity of the Debentures will be made in the following manner. On or before 11:00 a.m. (Toronto time) on the Business Day immediately prior to each maturity date for Debentures outstanding from time to time under this Indenture, the Company shall have transferred funds to the Debenture Trustee by electronic transfer of funds (provided the Debenture Trustee must have received confirmation of receipt of such funds on or before such time) in an amount sufficient to pay the cash amount payable in respect of such Debentures (including the principal amount and premium (if any), together with any accrued and unpaid interest thereon less any tax required by law to be deducted), provided the Company may elect to satisfy this requirement by providing the Debenture Trustee with a

certified cheque or a banker’s draft for such amounts required under this Section 2.12 post-dated to the applicable maturity date. The Debenture Trustee, on behalf of the Company, will pay to each holder entitled to receive payment the principal amount of and premium (if any) and accrued and unpaid interest on the Debenture (less applicable withholding taxes, if any), upon surrender of the Debenture at any branch of the Debenture Trustee designated for such purpose from time to time by the Company and the Debenture Trustee. The delivery of such funds to the Debenture Trustee will satisfy and discharge the liability of the Company for the Debentures to which the delivery of funds relates to the extent of the amount delivered (plus the amount of tax deducted of as aforesaid) and such Debentures will thereafter to that extent not be considered as outstanding under this Indenture and such holder will have no other right in regard thereto other than to receive out of the money so delivered or made available the amount to which such holder is entitled.

2.13

Payment of Interest

The following provisions shall apply to Debentures, except as otherwise provided in Section 2.4(b) or specified in a resolution of the Directors, a Certificate of the Company or a supplemental indenture relating to a particular series of Additional Debentures:

(a)

As interest becomes due on each Debenture (except on redemption, when interest may at the option of the Company be paid upon surrender of such Debenture) the Company, either directly or through the Debenture Trustee or any agent of the Debenture Trustee, shall send or forward by prepaid ordinary mail, electronic transfer of funds or such other means as may be agreed to by the Debenture Trustee, payment of such interest (less any tax required to be withheld therefrom) to the order of the registered holder of such Debenture appearing on the registers maintained by the Debenture Trustee at the close of business on the Business Day prior to the applicable Interest Payment Date and addressed to the holder at the holder’s last address appearing on the register, unless such holder otherwise directs. If payment is made by cheque or by other means such as electronic transfer of funds, provided the Debenture Trustee must receive confirmation of receipt of funds prior to being able to wire funds to holders, such payment shall be forwarded at least three Business Days prior to each date on which interest 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 is not paid at par on presentation. In the event of non-receipt of any cheque for or other payment of interest by the person to whom it is so sent as aforesaid, the Company or the Debenture Trustee will issue to such person a replacement cheque or other payment for a like amount upon being furnished with such evidence of non-receipt as it shall reasonably require and upon being indemnified to its satisfaction. Notwithstanding the foregoing, if the Company is prevented by circumstances beyond its control (including, without limitation, any interruption in mail service) from making payment of any interest due on each Debenture in the manner provided above, the Company may make payment of such interest or make such interest available for payment in any other manner acceptable to the

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

(b)

Notwithstanding Section 2.13(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 to the Debenture Trustee or any paying agent, or cheque made payable to the Depository or its nominee, for subsequent payment (less applicable withholding taxes, if any) to Beneficial Holders of interests in that Global Debenture prior to the day interest is payable, unless the Company and the Depository otherwise agree (upon prior written notice to the Debenture Trustee and any such paying agent). None of the Company, the Debenture Trustee or any agent of the Debenture 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.

2.14

Withholding Tax

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

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

ARTICLE 3

REGISTRATION, TRANSFER, EXCHANGE AND OWNERSHIP

3.1

Registered Debentures

(a)

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

(b)

No transfer of a Registered Debenture shall be valid unless made on such register referred to in Section 3.1(a) by the registered holder or such holder’s executors, administrators or other legal representatives or an attorney duly appointed by an instrument in writing in form and execution satisfactory to the Debenture Trustee or other registrar upon surrender of the Debentures together with a duly executed form of transfer acceptable to the Debenture Trustee and upon compliance with such other reasonable requirements as the Debenture Trustee or other registrar may prescribe, nor unless the name of the transferee shall have been noted on the Debenture by the Debenture Trustee or other registrar.

If any Debentures of such series are at any time not Global Debentures, the provisions of Section 3.1 shall govern with respect to registrations and transfers of such Debentures.

(b)

Notwithstanding any other provision of this Indenture, a Global Debenture may not be transferred by the registered holder thereof and accordingly, no definitive certificates shall be issued to Beneficial Holders of Debentures except in the following circumstances or as otherwise specified in a resolution of the Directors,

Certificate of the Company or supplemental indenture relating to a particular series of Debentures:

(i)

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

(ii)

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

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

(iv)

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

(v)

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

(vi)

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

the Company and the Debenture Trustee may deal with the Depository for all purposes (including paying interest on the Debentures) as the sole holder of such series of Debentures and the authorized representative of the Beneficial Holders;

(ii)

the rights of the Beneficial Holders shall be exercised only through the Depository and shall be limited to those established by law and

agreements between such Beneficial Holders and the Depository or the Depository Participants;

(iii)

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

(iv)

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

(d)

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

of the person registered as the holder thereof, whether named as trustee or otherwise, as though that person were the beneficial owner ▇▇▇▇▇▇▇.

3.5

Registers Open for Inspection

The registers referred to in Sections 3.1 and 3.2 shall at all reasonable times during the regular business hours of the Debenture Trustee be open for inspection by the Company, the Debenture Trustee or any Debentureholder.

3.6

Exchanges of Debentures

(a)

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

(b)

In respect of exchanges of Debentures permitted by Section 3.6(a), Debentures of any series may be exchanged only at the principal offices of the Debenture Trustee in Toronto or at such other place or places, if any, as may be specified in the Debentures of such series and at such other place or places as may from time to time be designated by the Company with the approval of the Debenture Trustee. Any Debentures tendered for exchange shall be surrendered to the Debenture Trustee. The Company shall execute and the Debenture Trustee shall certify all Debentures necessary to carry out exchanges as aforesaid. All Debentures surrendered for exchange shall be cancelled.

(c)

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

3.7

Closing of Registers

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

(iii)

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

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

3.8

Charges for Registration, Transfer and Exchange

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

(a)

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

(b)

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

(c)

for any exchange of any Debenture resulting from a partial redemption under Section 4.2 or Section 5.2; or

for any exchange of any Debenture resulting from a partial purchase under Section 2.4(g).

3.9

Ownership of Debentures

(a)

Unless otherwise required by law, the Person in whose name any registered Debenture is registered shall for all the purposes of this Indenture be and be deemed to be the owner thereof and payment of or on account of the principal of

and premium, if any, on such Debenture and interest thereon shall be made to such registered holder.

(b)

Neither the Company nor the Debenture Trustee shall have any liability for:

(i)

any aspect of the records relating to the beneficial ownership of the Debentures held by a Depository or of the payments relating thereto; or

(ii)

maintaining, supervising or reviewing any records relating to the Debentures [held by a Depository].

The rules governing Depositories provide that they act as the agent and depository for Depository Participants. As a result, such Depository Participants must look solely to the Depository and Beneficial Holders of Debentures must look solely to the Depository Participants for the payment of principal and interest on the Debentures paid by or on behalf of the Company to the Depository.

(c)

The registered holder for the time being of any registered Debenture shall be entitled to the principal, premium, if any, and/or interest evidenced by such instruments, respectively, free from all equities or rights of set-off or counterclaim between the Company and the original or any intermediate holder thereof and an Persons may act accordingly and the receipt of any such registered holder for any such principal, premium or interest shall be a good discharge to the Company and/or the Debenture Trustee for the same and neither the Company nor the Debenture Trustee shall be bound to inquire into the title of any such registered holder.

(d)

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

(e)

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

ARTICLE 4

REDEMPTION AND PURCHASE OF DEBENTURES AT THE OPTION OF THE COMPANY

4.1

Applicability of Article

The Company shall have the right, at its option, to redeem, either in whole or in part before maturity, 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 a Certificate of the Company, 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 Company 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, the Debentures to be so redeemed shall be selected by the Debenture Trustee on a pro rata basis to the nearest multiple of $100 in accordance with the principal amount of the Debentures registered in the name of each holder or in such other manner as the Debenture Trustee deems equitable, subject to the approval of the TSX. 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 $100 or a multiple thereof. For this purpose, the Debenture 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 holders of such Debentures 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 Call Date, the Company shall execute and the Debenture Trustee shall certify and deliver without charge to the holder thereof or upon the holder’s order one or more new Debentures for the unredeemed part of the principal amount of the Debenture or Debentures so surrendered or, with respect to a Global Debenture, the Depository 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 “Call Notice”) of any series of Debentures pursuant to this Article 4 shall be given to the holders of the Debentures so to be redeemed in the manner provided in the terms of such series of Debentures and the date fixed for redemption (the “Redemption Call Date”) will be set out in the applicable Call Notice. Every such notice shall specify the aggregate principal amount of Debentures called for redemption, the Redemption Call Date, the Redemption Price and the places of payment and shall state that interest upon the principal amount of Debentures called for redemption shall cease to accrue and be payable from and after the Redemption Call Date. In addition, unless all the outstanding Debentures are to be redeemed, the Call Notice shall specify:

(a)

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

(b)

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

(c)

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

(d)

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

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

4.4

Debentures Due on Redemption Call Dates

Notice having been given as aforesaid, all the Debentures so called for redemption shall thereupon be and become due and payable at the Redemption Price, together with accrued and unpaid interest to but excluding the Redemption Call Date (less any taxes required to be deducted or withheld), on the Redemption Call Date specified in such notice, in the same manner and with the same effect as if it were the date of maturity specified in such Debentures, anything therein or herein to the contrary notwithstanding, and from and after such Redemption Call Date, if the moneys necessary to redeem such Debentures shall have been deposited as provided in Section 4.5 and affidavits or other proof satisfactory to the Debenture Trustee as to the publication and/or mailing of such notices shall have been lodged with it, interest upon the Debentures shall cease. If any question shall arise as to whether any notice has been given as above provided and such deposit made, such question shall be decided by the Debenture Trustee, acting reasonably, whose decision shall be final and binding upon all parties in interest.

4.5

Deposit of Redemption Moneys

Redemption of Debentures shall be provided for by the Company depositing with the Debenture Trustee or any paying agent to the order of the Debenture Trustee, on or before 11:00 a.m. (Toronto time) on the Business Day immediately prior to the Redemption Call Date specified in such notice, such sums of money as may be sufficient to pay the Redemption Price of the Debentures so called for redemption, plus accrued and unpaid interest thereon to but excluding the Redemption Call Date, provided the Company may elect to satisfy this requirement by providing the Debenture Trustee with a certified cheque or a banker’s draft for such amounts required under this Section 4.5 or by providing the Debenture Trustee with such funds through electronic transfer of funds on the Business Day immediately prior to the Redemption Call Date. The Company shall also deposit with the Debenture Trustee a sum of money sufficient to pay any charges or expenses that may be incurred by the Debenture Trustee in connection with such redemption. Every such deposit shall be irrevocable. From the sums so deposited, the Debenture Trustee shall pay or cause to be paid, or issue or cause to be issued, to the holders of such Debentures so called for redemption, upon surrender of such Debentures, the principal, premium (if any) and interest (if any) to which they are respectively entitled on redemption, less applicable

withholding taxes, if any. If the money so transferred is insufficient to satisfy the Company’s obligations to the redeeming holders, or the fees and expenses of the Debenture Trustee relating to the redemption, the Debenture Trustee or the paying agent for the redemption shall notify the Company, and the Company shall deposit additional sums of money with the Debenture Trustee or any paying agent to the order of the Debenture Trustee. Any costs or losses resulting from a delay resulting from insufficient funds shall be borne by the Company.

4.6

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 Call Date to surrender such holder’s Debenture, or shall not within such time accept payment of the redemption moneys payable or give such receipt therefor, if any, as the Debenture Trustee may require, such redemption moneys may be set aside in trust without interest, either in the deposit department of the Debenture Trustee or in a Canadian chartered bank, and such setting aside shall for all purposes be deemed a payment to the Debentureholder of the sum so set aside and, to that extent, the Debenture shall thereafter not be considered as outstanding hereunder and the Debentureholder shall have no other right except to receive payment out of the moneys so paid and deposited upon surrender and delivery up of such holder’s Debenture of the Redemption Price, as the case may be, of such Debenture plus any accrued but unpaid interest thereon to but excluding the Redemption Call Date. In the event that any money required to be deposited hereunder with the Debenture Trustee or any depository or paying agent on account of Redemption Price, or interest, if any, on Debentures issued hereunder shall remain so deposited for a period of three years from the Redemption Call Date, then such monies, together with any accumulated interest thereon or any distribution paid thereon, shall at the end of such period be paid over or delivered over by the Debenture Trustee or such Depository or paying agent to the Company on its demand, and thereupon the Debenture Trustee shall not be responsible to Debentureholders for any amounts owing to them and subject to applicable law, thereafter the holder of a Debenture in respect of which such money was so repaid to the Company shall have no rights in respect thereof except to obtain payment of the money due from the Company, subject to any limitation period provided by the laws of Ontario. Notwithstanding the foregoing, the Debenture Trustee will pay any remaining funds prior to the expiry of three years after the Redemption Call Date to the Company upon receipt from the Company, of an unconditional letter of credit from a Canadian chartered bank in an amount equal to or in excess of the amount of the remaining funds. If the remaining funds are paid to the Company prior to the expiry of three years after the Redemption Call Date, the Company shall reimburse the Debenture Trustee for any amounts required to be paid by the Debenture Trustee to a holder of a Debenture pursuant to the redemption after the date of such payment of the remaining funds to the Company but prior to three years after the redemption.

4.7

Cancellation of Debentures Redeemed

Subject to the provisions of Sections 4.2 and 4.8 as to Debentures redeemed or purchased in part, all Debentures redeemed and paid under this Article 4 shall forthwith be delivered to the Debenture Trustee and cancelled and no Debentures shall be issued in substitution therefor.

4.8

Purchase of Debentures by the Company

Unless otherwise specifically provided with respect to a particular series of Debentures, the Company or any of its Affiliates may at any time and from time to time, purchase Debentures in the market (which shall include purchases from or through an investment dealer or a firm holding membership on a Recognized Stock Exchange) or by tender or by private contract, at any price; provided that if an Event of Default has occurred and is continuing, the Company will not have the right to purchase the Debentures by private contract. All Debentures so purchased may, at the option of the Company, be delivered to the Debenture Trustee and shall be cancelled and no Debentures shall be issued in substitution therefor.

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

ARTICLE 5

INVESTOR PUT RIGHT

5.1

Applicability of Article

Each Debentureholder shall have the right, at its option, to require the Company to redeem, either in whole or in part before maturity, any Debentures issued hereunder of any series which by their terms are permitted to be redeemed (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 a Certificate of the Company, 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 Company requesting the certification and delivery thereof.

5.2

Partial Redemption

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 $100 or a multiple thereof. For this purpose, the Debenture 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 holders of such Debentures 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 Put Date, the Company shall execute and the Debenture Trustee shall certify and deliver without charge to the holder thereof or upon the holder’s order one or more new Debentures for the unredeemed part of the principal amount of the Debenture or Debentures so surrendered or, with respect to a Global Debenture, the Depository 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 5 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.

5.3

Notice of Redemption

Notice of redemption (the “Put Notice”) of any series of Debentures pursuant to this Article 5 shall be given to the Company in the manner provided in the terms of such series of Debentures, and the date fixed for redemption (the “Redemption Put Date”) will be set out in the applicable Put Notice. Every such notice shall specify the aggregate principal amount of Debentures to be redeemed by the Company, the Redemption Put Date, the Redemption Price and the places of payment and shall state that interest upon the principal amount of Debentures called for redemption shall cease to accrue and be payable from and after the Redemption Put Date. In addition, the Put 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 Global Debenture, that the redemption will take place in such manner as may be agreed upon by the Depository, the Debenture Trustee and the Company; and

(c)

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.

5.4

Debentures Due on Redemption Put Dates

the same effect as if it were the date of maturity specified in such Debentures, anything therein or herein to the contrary notwithstanding, and from and after such Redemption Put Date, if the moneys necessary to redeem such Debentures shall have been deposited as provided in Section 5.5 and affidavits or other proof satisfactory to the Debenture Trustee as to the publication and/or mailing of such notices shall have been lodged with it, interest upon the Debentures shall cease. If any question shall arise as to whether any notice has been given as above provided and such deposit made, such question shall be decided by the Debenture Trustee, acting reasonably, whose decision shall be final and binding upon all parties in interest.

5.5

Deposit of Redemption Moneys

Redemption of Debentures shall be provided for by the Company depositing with the Debenture Trustee or any paying agent to the order of the Debenture Trustee, on or before 11:00 a.m. (Toronto time) on the Business Day immediately prior to the Redemption Put Date specified in such notice, such sums of money as may be sufficient to pay the Redemption Price of the Debentures so called for redemption, plus accrued and unpaid interest thereon to but excluding the Redemption Put Date, provided the Company may elect to satisfy this requirement by providing the Debenture Trustee with a certified cheque or a banker’s draft for such amounts required under this Section 5.5 or by providing the Debenture Trustee with such funds through electronic transfer of funds on the Business Day immediately prior to the Redemption Put Date. The Company shall also deposit with the Debenture Trustee a sum of money sufficient to pay any charges or expenses that may be incurred by the Debenture Trustee in connection with such redemption. Every such deposit shall be irrevocable. From the sums so deposited, the Debenture Trustee shall pay or cause to be paid, or issue or cause to be issued, to the holders of such Debentures so called for redemption, upon surrender of such Debentures, the principal, premium (if any) and interest (if any) to which they are respectively entitled on redemption, less applicable withholding taxes, if any. If the money so transferred is insufficient to satisfy the Company’s obligations to the redeeming holders, or the fees and expenses of the Debenture Trustee relating to the redemption, the Debenture Trustee or the paying agent for the redemption shall notify the Company, and the Company shall deposit additional sums of money with the Debenture Trustee or any paying agent to the order of the Debenture Trustee. Any costs or losses resulting from a delay resulting from insufficient funds shall be borne by the Company.

5.6

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 Put Date to surrender such holder’s Debenture, or shall not within such time accept payment of the redemption moneys payable or give such receipt therefor, if any, as the Debenture Trustee may require, such redemption moneys may be set aside in trust without interest, either in the deposit department of the Debenture Trustee or in a Canadian chartered bank, and such setting aside shall for all purposes be deemed a payment to the Debentureholder of the sum so set aside and, to that extent, the Debenture shall thereafter not be considered as outstanding hereunder and the Debentureholder shall have no other right except to receive payment out of the moneys so paid and deposited upon surrender and delivery up of such holder’s Debenture of the Redemption Price, as the case may be, of such Debenture plus any accrued but unpaid interest thereon to but excluding the Redemption Put Date. In the event that any money required to be deposited hereunder with the Debenture Trustee or any depository or

paying agent on account of Redemption Price, or interest, if any, on Debentures issued hereunder shall remain so deposited for a period of three years from the Redemption Put Date, then such monies, together with any accumulated interest thereon or any distribution paid thereon, shall at the end of such period be paid over or delivered over by the Debenture Trustee or such Depository or paying agent to the Company on its demand, and thereupon the Debenture Trustee shall not be responsible to Debentureholders for any amounts owing to them and subject to applicable law, thereafter the holder of a Debenture in respect of which such money was so repaid to the Company shall have no rights in respect thereof except to obtain payment of the money due from the Company, subject to any limitation period provided by the laws of Ontario. Notwithstanding the foregoing, the Debenture Trustee will pay any remaining funds prior to the expiry of three years after the Redemption Put Date to the Company upon receipt from the Company, of an unconditional letter of credit from a Canadian chartered bank in an amount equal to or in excess of the amount of the remaining funds. If the remaining funds are paid to the Company prior to the expiry of three years after the Redemption Put Date, the Company shall reimburse the Debenture Trustee for any amounts required to be paid by the Debenture Trustee to a holder of a Debenture pursuant to the redemption after the date of such payment of the remaining funds to the Company but prior to three years after the redemption.

ARTICLE 6

SUBORDINATION OF DEBENTURES

6.1

Subordination and Postponement

The indebtedness evidenced by the Debentures issued hereunder, whether on account of principal, interest or otherwise (collectively the “Debenture Liabilities”), shall, notwithstanding any other provision herein or in the Debentures, be subordinated and postponed and subject in right of payment, to the full and final payment in cash (or as otherwise agreed by the Senior Creditors in respect of the Senior Indebtedness) of all Senior Indebtedness until Payment in Full of the Senior Indebtedness and each holder of any such Debenture by his acceptance thereof agrees to and shall be bound by the provisions of this Article 6, provided that the Company may continue to make payments on account of interest on the Debentures as they come due unless and until a default or an event of default (as defined in, or under, any Senior Indebtedness or any instrument evidencing the same) has occurred and is continuing or unless otherwise prohibited by the terms of the Senior Indebtedness (or any instrument evidencing the same).

6.2

Order of Payment

In the event of any dissolution, winding-up, liquidation, bankruptcy, insolvency, receivership, creditor enforcement, reorganization or realization or other similar proceedings relating to the

Company or any of its property or assets or any other marshalling of the assets and liabilities of the Company:

(a)

all Senior Indebtedness shall first be paid in full in cash (or as otherwise agreed by the Senior Creditors in respect of the Senior Indebtedness) before any payment or distribution of any kind of character, whether in cash, property or securities, is made on account of Debenture Liabilities; and

(b)

any payment or distribution of assets of the Company, whether in cash, property or securities, to which the holders of the Debentures or the Debenture Trustee on behalf of such holders would be entitled except for the provisions of this Article 6, shall be paid or delivered by the trustee in bankruptcy, receiver, assignee for the benefit of creditors, or other liquidating agent making such payment or distribution, directly to the holders of Senior Indebtedness or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any of such Senior Indebtedness may have been issued, to the extent necessary to pay all Senior Indebtedness in full in cash (or as otherwise agreed by the Senior Creditors in respect of the Senior Indebtedness) after giving effect to any concurrent payment or distribution, or provision therefor, to the holders of such Senior Indebtedness.

Neither the Debenture Trustee nor the Debentureholders shall be entitled to demand or otherwise attempt to enforce in any manner, institute proceedings for the collection of, or institute any proceedings against the Company including, without limitation, by way of any bankruptcy, insolvency or similar proceedings or any proceeding for the appointment of a receiver, liquidator, trustee or other similar official (it being understood and agreed that the Debenture Trustee and/or the Debentureholders in any such proceeding and any steps necessary to prevent the extinguishment or other termination of a claim or potential claim as a result of the expiry of a limitation period), or receive any payment or benefit in any manner whatsoever on account of indebtedness represented by the Debentures at any time when an event of default has occurred and is continuing under any Senior Indebtedness and, in each case, notice of such event of default has been given by or on behalf of the Senior Creditors.

6.3

Subrogation to Rights of Holders of Senior Indebtedness

Until Payment in Full of the Senior Indebtedness, the holders of the Debentures shall be subrogated to the rights of the holders of Senior Indebtedness to receive payments or distributions of assets of the Company to the extent of the application thereto of such payments or other assets which would have been received by the holders of the Debentures but for the provisions hereof and no such payments or distributions to the holders of the Debentures of cash, property or securities, which otherwise would be payable or distributable to the holders of the Senior Indebtedness, shall, as between the Company, its creditors other than the holders of Senior Indebtedness, and the holders of Debentures, be deemed to be a payment by the Company to the holders of the Senior Indebtedness or on account of the Senior Indebtedness, it being understood that the provisions of this Article 6 are and are intended solely for the purpose of defining the relative rights of the holders of the Debentures, on the one hand, and the holders of Senior Indebtedness, on the other hand.

6.4

Obligation to Pay Not Impaired

Nothing contained in this Article 6 or elsewhere in this Indenture or in the Debentures is intended to or shall impair, as between the Company, its creditors other than the holders of Senior Indebtedness, and the holders of the Debentures, the obligation of the Company, which is absolute and unconditional, to pay to the holders of the Debentures the principal of and interest on the Debentures, as and when the same shall become due and payable in accordance with their terms, or affect the relative rights of the holders of the Debentures and creditors of the Company other than the holders of the Senior Indebtedness, nor shall anything herein or therein prevent the Debenture Trustee or the holder of any Debenture from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights under this Article 6 of the holders of Senior Indebtedness.

6.5

Payment on Debentures Permitted

Nothing contained in this Article 6 or elsewhere in this Indenture, or in any of the Debentures, shall affect the obligation of the Company to make, or prevent the Company from making, at any time except as prohibited by Section 6.1 or 6.2, any payment of principal of or interest on the Debentures. The fact that any such payment is prohibited by Section 6.1 or 6.2 shall not prevent the failure to make such payment from being an Event of Default hereunder. Nothing contained in this Article 6 or elsewhere in this Indenture, or in any of the Debentures, shall prevent the application by the Debenture Trustee of any moneys deposited with the Debenture Trustee hereunder for the purpose, to the payment of or on account of the Debenture Liabilities.

6.6

Confirmation of Subordination

Each holder of Debentures by his acceptance thereof authorizes and directs the Debenture Trustee on his behalf to take such action as may be necessary or appropriate to effect the subordination and postponement as provided in this Article 6 and appoints the Debenture Trustee his attorney for any and all such purposes. This power of attorney, being coupled with an interest and rights, shall be irrevocable. Upon request of the Company or a Senior Creditor or any representative of the Senior Creditors, and upon being furnished a Certificate of the Company or a certificate of a Senior Creditor or a representative of a Senior Creditor stating that one or more named persons are Senior Creditors and specifying the amount and nature of the Senior Indebtedness of such Senior Creditor, the Debenture Trustee shall enter into a written agreement or agreements with such Person and the person or persons named therein providing that such person or persons are entitled to all the rights and benefits of this Article 6 as a Senior Creditor. Such agreement shall be conclusive evidence that the indebtedness specified therein is Senior Indebtedness. However, nothing herein shall impair the rights of any Senior Creditor who has not entered into such an agreement.

6.7

Knowledge of Debenture Trustee

Notwithstanding the provisions of this Article 6 or any provision in this Indenture or in the Debentures contained, the Debenture Trustee will not be charged with knowledge of any Senior Indebtedness or of any default in the payment thereof or any other default or event of default, or of the existence of any other fact that would prohibit the making of any payment of moneys to or

by the Debenture Trustee, or the taking of any other action by the Debenture Trustee, unless and until the Debenture Trustee has received written notice thereof from the Company, any Debentureholder, any Senior Creditor or a representative or trustee on behalf of any one or more Senior Creditors, and such notice to the Debenture Trustee shall be deemed to be notice to holders of the Debentures.

6.8

Debenture Trustee May Hold Senior Indebtedness

The Debenture Trustee is entitled to all the rights set forth in this Article 6 with respect to any Senior Indebtedness at the time held by it, if any, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture deprives the Debenture Trustee of any of its rights as such holder.

6.9

Rights of Holders of Senior Indebtedness Not Impaired

No right of any present or future holder of any Senior Indebtedness 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 Company, or any guarantor or surety of the Senior Indebtedness, or by any non-compliance by the Company, or any such guarantor or surety, with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or be otherwise charged with.

6.10

Altering the Senior Indebtedness

The holders of the Senior Indebtedness have the right to increase, extend, renew, revise, restate, modify or amend the terms of the Senior Indebtedness or any security therefor and to release, sell or exchange such security and otherwise to deal freely with the Company, all without notice to or consent of the Debentureholders or the Debenture Trustee and without affecting the liabilities and obligations of the parties to this Indenture or the Debentureholders or the Debenture Trustee.

6.11

Additional Indebtedness

This Indenture does not restrict the Company from incurring additional indebtedness for borrowed money (including Senior Indebtedness) or otherwise or mortgaging, pledging or charging its properties to secure any indebtedness.

6.12

Invalidated Payments

In the event that any of the Senior Indebtedness shall be paid in full and subsequently, for whatever reason, such formerly paid or satisfied Senior Indebtedness becomes unpaid or unsatisfied, the terms and conditions of this Article 6 shall be reinstated and the provisions of this Article shall again be operative until all Senior Indebtedness is repaid in full, provided that such reinstatement shall not give the Senior Creditors any rights or recourses against the Debenture Trustee or the Debentureholders for amounts paid to the Debentureholders subsequent to such payment or satisfaction in full and prior to such reinstatement.

6.13

Obligations Created by Article 6

The Company and the Debenture Trustee, solely in its capacity as trustee hereunder and not in its personal capacity agree, and each holder by its acceptance of a Debenture likewise agrees, that:

(a)

the provisions of this Article 6 are an inducement and consideration to each holder of Senior Indebtedness to give or continue credit to the Company, its Subsidiaries or others or to acquire Senior Indebtedness;

(b)

each holder of Senior Indebtedness may accept the benefit of this Article 6 on the terms and conditions set forth in this Article 6 by giving or continuing credit to the Company, its Subsidiaries or others or by acquiring Senior Indebtedness, in each case without notice to the Debenture Trustee and without establishing actual reliance on this Article 6; and

(c)

each obligation created by this Article 6 is created for the benefit of the holders of Senior Indebtedness and is hereby declared to be created in trust for those holders by the Company, the Debenture Trustee and each holder of a Debenture and shall be binding on the Company, the Debenture Trustee and each holder of a Debenture whether or not the confirmation described in Section 6.6 is requested, executed or delivered.

6.14

No Set-Off

Each of the Company and the Debenture Trustee agrees, and each holder of a Debenture, by his acceptance thereof, likewise agrees, that it shall have no rights of set-off or counterclaim with respect to the principal of, premium, if any, and interest on the Debentures at any time when any payment of, or in respect of, such amounts to the Debenture Trustee or the holder of a Debenture is prohibited by this Article 6 or is otherwise required to be paid to the holders of Senior Indebtedness or their representative or to the trustee under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued, as their respective interests may appear.

ARTICLE 7

7.7

Performance of Covenants by Debenture Trustee

If the Company shall fail to perform any of its covenants contained in this Indenture, the Debenture Trustee may notify the Debentureholders of such failure on the part of the Company or may itself perform any of the covenants capable of being performed by it, but (subject to Sections 8.2 and 13.3) shall be under no obligation to do so or to notify the Debentureholders. All sums so expended or advanced by the Debenture Trustee shall be repayable as provided in

Section 7.2. No such performance, expenditure or advance by the Debenture Trustee shall be deemed to relieve the Company of any default hereunder or from its continuing indebtedness.

ARTICLE 8

DEFAULT

8.1

Events of Default

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

(a)

failure to pay principal or premium, if any, on the Debentures when due whether at maturity, upon redemption, by declaration or otherwise and the continuance of such default for 30 days;

(b)

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

(c)

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

(d)

if a resolution is passed for the winding-up or liquidation of the Company except in the course of carrying out or pursuant to a transaction in respect of which the conditions of Section 10.1 are duly observed and performed; or

(e)

if, after the date of this Indenture, any proceedings with respect to the Company are taken with respect to a compromise or arrangement, with respect to creditors of the Company generally, under the applicable legislation of any jurisdiction and such proceeding, if instituted against the Company is not contested diligently, in good faith and on a timely basis and vacated, dismissed, withdrawn or stayed within 60 days of its commencement or issuance;

in each and every such event the Debenture Trustee may, in its discretion, and shall, upon receipt of a request in writing signed by the holders of not less than 25% in principal amount of the Debentures then outstanding and upon being indemnified to its reasonable satisfaction against all costs, expenses and liabilities to be incurred, subject to the provisions of Section 8.3, by notice in writing to the Company declare the principal of,

premium, if any, and interest on all Debentures then outstanding and all other moneys outstanding hereunder to be due and payable and the same shall forthwith become immediately due and payable to the Debenture Trustee, and the Company shall forthwith pay to the Debenture Trustee for the benefit of the Debentureholders such principal, accrued and unpaid interest and interest on amounts in default on such Debenture (and, where such a declaration is based upon a voluntary winding-up or liquidation of the Company, the premium, if any, on the Debentures then outstanding which would have been payable upon the redemption thereof by the Company on the date of such declaration) and all other moneys outstanding hereunder, together with subsequent interest at the rate borne by the Debentures on such principal, interest and such other moneys from the date of such declaration until payment is received by the Debenture Trustee, such subsequent interest to be payable at the times and places and in the moneys mentioned in and according to the tenor of the Debentures. Such payment when made shall be deemed to have been made in discharge of the Company’s obligations hereunder and any moneys so received by the Debenture Trustee shall be applied in the manner provided in Section 8.6. For greater certainty, for the purposes of this Section 8.1, a series of Debentures shall be in default in respect of an Event of Default if such Event of Default relates to a default in the payment of principal, premium, if any, or interest on the Debentures of such series in which case references to Debentures in this Section 8.1 refer to Debentures of that particular series. For purposes of this Article 8, where the Event of Default refers to an Event of Default with respect to a particular series of Debentures as described in this Section 8.1, then this Article 8 shall apply mutatis mutandis to the Debentures of such series and references in this Article 8 to the Debentures shall mean Debentures of the particular series and references to the Debentureholders shall refer to the Debentureholders of the particular series, as applicable.

8.2

Notice of Events of Default

If an Event of Default shall occur and be continuing the Debenture 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 12.1, provided that notwithstanding the foregoing, unless the Debenture Trustee shall have been requested to do so by the holders of at least 25% of the principal amount of the Debentures then outstanding, the Debenture Trustee shall not be required to give such notice if the Debenture Trustee in good faith shall have determined that the withholding of such notice is in the best interests of the Debentureholders and shall have so advised the Company in writing.

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

8.3

Waiver of Default

Upon the happening of any Event of Default hereunder:

(a)

the holders of the Debentures shall have the power (in addition to the powers exercisable by Extraordinary Resolution as hereinafter provided) by requisition in writing by the holders of a 66 2/3% of the principal amount of Debentures then outstanding or by Extraordinary Resolution of Debentureholders at a meeting held in accordance with Article — hereof, to instruct the Debenture Trustee to waive any Event of Default and to cancel any declaration made by the Debenture Trustee pursuant to Section 8.1 and the Debenture Trustee shall thereupon waive the Event of Default and cancel such declaration 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 Company of any covenant applicable only to one or more series of Debentures, then the holders of at least 66 2/3 % of the principal amount of the outstanding Debentures of that series shall be entitled to exercise the foregoing power and the Debenture Trustee shall so act and it shall not be necessary to obtain a waiver from the holders of any other series of Debentures; and

(b)

the Debenture 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 Debenture Trustee’s opinion, based on the advice of counsel, the same shall have been cured or adequate satisfaction made therefor, and in such event to cancel any such declaration theretofore made by the Debenture Trustee in the exercise of its discretion, upon such terms and conditions as the Debenture Trustee may deem advisable.

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

8.4

Enforcement by the Debenture Trustee

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

The Debenture Trustee shall be entitled and empowered, either in its own name or as Debenture Trustee of an express trust, or as attorney-in-fact for the holders of the Debentures, or in any one or more of such capacities, to file such proof of debt, amendment of proof of debt, claim, petition or other document as may be necessary or advisable in order to have the claims of the Debenture Trustee and of the holders of the Debentures allowed in any insolvency, bankruptcy, liquidation or other judicial proceedings relative to the Company or its creditors or relative to or affecting its property. The Debenture Trustee is hereby irrevocably appointed (and the successive respective holders of the Debentures by taking and holding the same shall be conclusively deemed to have so appointed the Debenture Trustee) the true and lawful attorney-in-fact of the respective holders of the Debentures with authority to make and file in the respective names of the holders of the Debentures or on behalf of the holders of the Debentures as a class, subject to deduction from any such claims of the amounts of any claims filed by any of the holders of the Debentures themselves, any proof of debt, amendment of proof of debt, claim, petition or other document in any such proceedings and to receive payment of any sums becoming distributable on account thereof, and to execute any such other papers and documents and to do and perform any and all such acts and things for and on behalf of such holders of the Debentures, as may be necessary or advisable in the opinion of the Debenture Trustee, in order to have the respective claims of the Debenture Trustee and of the holders of the Debentures against the Company or its property allowed in any such proceeding, and to receive payment of or on account of such claims; provided, however, that subject to Section 8.3, nothing contained in this Indenture shall be deemed to give to the Debenture 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 Debenture 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 Debenture 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 Debenture Trustee shall be brought in the name of the Debenture Trustee as trustee of an express trust, and any recovery of judgment shall be for the rateable benefit of the holders of the Debentures subject to the provisions of this Indenture. In any proceeding brought by the Debenture 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 Debenture Trustee shall be a party) the Debenture Trustee shall be held to represent all the holders of the Debentures, and it shall not be necessary to make any holders of the Debentures parties to any such proceeding.

8.5

8.6

Application of Moneys by Debenture Trustee

(a)

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

(i)

first, in payment or in reimbursement to the Debenture Trustee of its compensation, costs, charges, expenses, borrowing, advances or other moneys furnished or provided by or at the instance of the Debenture Trustee in or about the execution of its trusts under, or otherwise in relation to, this Indenture, with interest thereon as herein provided;

(iii)

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

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 Company or any Subsidiary (other than any Debenture pledged for value and in good faith to a person other than the Company

or any Subsidiary but only to the extent of such person’s interest therein) except subject to the prior payment in full of the principal, premium (if any) and interest (if any) on all Debentures which are not so held.

(b)

The Debenture 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 Debenture Trustee may think necessary to provide for the payments mentioned in Section 8.6(a), is insufficient to make a distribution of at least 2% of the aggregate principal amount of the outstanding Debentures, but it may retain the money so received by it and invest or deposit the same as provided in Section 13.9 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.

8.7

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

8.9

Remedies Cumulative

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

8.10

9.2

Non-Presentation of Debentures

In case the holder of any Debenture shall fail to present the same for payment on the date on which the principal, premium (if any) or the interest thereon or represented thereby becomes payable either at maturity or otherwise or shall not accept payment on account thereof and give such receipt therefor, if any, as the Debenture Trustee may require:

(a)

the Company shall be entitled to pay or deliver to the Debenture Trustee and direct it to set aside; or

(b)

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

(c)

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

the principal, premium (if any) or the interest, as the case may be, in trust to be paid to the holder of such Debenture upon due presentation or surrender thereof in accordance with the provisions of this Indenture; and thereupon the principal, premium (if any) or the interest payable on or represented by each Debenture in respect whereof such moneys have been set aside shall be deemed to have been paid and the holder thereof shall thereafter have no right in respect thereof except that of receiving delivery and payment of the moneys (less applicable withholding taxes, if any), so set aside by the Debenture Trustee upon due presentation and surrender thereof.

9.3

Discharge

The Debenture Trustee shall at the written request of the Company release and discharge this Indenture and execute and deliver such instruments as it shall be advised by Counsel are requisite for that purpose and to release the Company from its covenants herein contained (other than the provisions relating to the indemnification of the Debenture Trustee), upon proof being given to the reasonable satisfaction of the Debenture Trustee that the principal and premium (if any) of and interest (including interest on amounts in default, if any), on all the Debentures and all other moneys payable hereunder have been paid or satisfied or that all the Debentures having matured or having been duly called for redemption, payment of the principal of and interest (including interest on amounts in default, if any) on such Debentures and of all other moneys payable hereunder has been duly and effectually provided for in accordance with the provisions hereof.

Subject to applicable law, any monies set aside under Section 9.2 and not claimed by and paid to holders of Debentures as provided in Section 9.2 within three years after the date of such setting aside shall be repaid and delivered to the Company by the Debenture Trustee and thereupon the Debenture Trustee shall be released from all further liability with respect to such monies and thereafter the holders of the Debentures in respect of which such monies were so repaid to the Company shall have no rights in respect thereof except to obtain payment and delivery of the monies from the Company subject to any limitation provided by the laws of the Province of Ontario. Notwithstanding the foregoing, the Debenture Trustee will pay any remaining funds prior to the expiry of three years after the setting aside described in Section 9.2 to the Company upon receipt from the Company, or one of its Subsidiaries (on behalf of the Company), of an uncontested letter of credit from a Canadian chartered bank in an amount equal to or in excess of the amount of the remaining funds. If the remaining funds are paid to the Company prior to the expiry of three years after such setting aside, the Company shall reimburse the Debenture Trustee for any amounts so set aside which are required to be paid by the Debenture Trustee to a holder of a Debenture after the date of such payment of the remaining funds to the Company but prior to three years after such setting aside.

9.5

Satisfaction

(a)

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

(i)

the Company has deposited or caused to be deposited with the Debenture Trustee as trust funds or property in trust for the purpose of making payment on such Debentures, an amount in money sufficient to pay, satisfy and discharge the entire amount of principal, premium, if any, and

interest, if any, to maturity or any repayment date, Redemption Call Dates or Redemption Put Dates, as the case may be, of such Debentures; or

if the Debentures are issued in a currency or currency unit other than Canadian dollars, cash in the currency or currency unit in which the Debentures are payable and/or such amount in such currency or currency unit of direct obligations of, or obligations the principal and interest of which are guaranteed by, the Government of Canada or the government that issued the currency or currency unit in which the Debentures are payable;

as will, together with the income to accrue thereon and reinvestment thereof, be sufficient to pay and discharge the entire amount of principal and accrued and unpaid interest to maturity or any repayment date, as the case may be, of all such Debentures; or

(iii)

all Debentures authenticated and delivered (other than (A) Debentures which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.9, and (B) Debentures for whose payment has been deposited in trust and thereafter repaid to the Company as provided in Section 9.4) have been delivered to the Debenture Trustee for cancellation;

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

(v)

in respect of (i) and (ii) above, the Company has delivered to the Debenture Trustee an opinion of Counsel reasonably acceptable to the Debenture Trustee and qualified to practice in Canada to the effect that holders of outstanding Debentures that are resident in Canada for purposes of the Tax Act will not recognize income, gain or loss for Canadian federal income tax purposes as a result of this Section 9.5(a)(v) and will only be subject to Canadian federal income taxes on the same amounts, in

the same manner and at the same times as would have been the case if this Section 9.5(a)(v) had not applied; and

(vi)

the Company has delivered to the Debenture Trustee a Certificate of the Company stating that all conditions precedent herein provided relating to the payment, satisfaction and discharge of all such Debentures have been complied with.

Any deposits with the Debenture Trustee referred to in this Section 9.5 shall be irrevocable, subject to Section 9.6, and shall be made under the terms of an escrow and/or trust agreement in form and substance satisfactory to the Debenture Trustee and which provides for the due and punctual payment of the principal of, and interest and premium, if any, on the Debentures being satisfied.

(b)

Upon the satisfaction of the conditions set forth in this Section 9.5 with respect to all the outstanding Debentures, or all the outstanding Debentures of any series, as applicable, the terms and conditions of the Debentures, including the terms and conditions with respect thereto set forth in this Indenture (other than those contained in Article 2, Article 4, Article 6, Section 8.4 and the provisions of Article 1 pertaining to the foregoing provisions) shall no longer be binding upon or applicable to the Company.

(c)

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

(d)

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

9.6

Continuance of Rights, Duties and Obligations

(a)

Where trust funds or trust property have been deposited pursuant to Section 9.5, the holders of Debentures and the Company shall continue to have and be subject to their respective rights, duties and obligations under Article 2, Article 4 and Article 6 and the provisions of Article 1 pertaining to the foregoing.

(b)

In the event that, after the deposit of trust funds or trust property pursuant to Section 9.5, the Company is required to make an Offer to Purchase any outstanding Debentures pursuant to Subsection 2.4(g) in relation to Initial Debentures or to make an offer to purchase Debentures pursuant to any other similar provisions relating to any other series of Debentures, the Company shall be entitled to use any trust money or trust property deposited with the Debenture Trustee pursuant to Section 9.5 for the purpose of paying to any holders of Defeased Debentures who have accepted any such offer of the Company the Offer Price payable to such holders in respect of such offer in respect of Initial Debentures (or the total offer price payable in respect of an offer relating to any other series of Debentures). Upon receipt of a Written Direction from the Company, the Debenture Trustee shall be entitled to pay to such holder from such trust money or trust property deposited with the Debenture Trustee pursuant to Section 9.5 in respect of the Defeased Debentures the amount which is applicable to the Defeased Debentures held by such holders who have accepted any such offer (which amount shall be based on the applicable principal amount of the Defeased Debentures held by accepting offerees in relation to the aggregate outstanding principal amount of all the Defeased Debentures).

(a)

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

(i)

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

(ii)

the Debentures will be valid and binding obligations of the Successor entitling the holders thereof, as against the Successor, to all the rights of Debentureholders under this Indenture; and

(iii)

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

10.2

Vesting of Powers in Successor

Whenever the conditions of Section 10.1 shall have been duly observed and performed, any Successor formed by or resulting from such transaction shall succeed to, and be substituted for, and may exercise every right and power of the Company under this Indenture with the same effect as though the Successor had been named as the Company herein and thereafter, except in the case of a lease or other similar disposition of property to the Successor, the Company shall be relieved of all obligations and covenants under this Indenture and the Debentures forthwith upon the Company delivering to the Debenture Trustee an opinion of Counsel to the effect that the transaction shall not result in any material adverse tax consequences to the Company or the Successor.

ARTICLE 11

MEETINGS OF DEBENTUREHOLDERS

11.1

Right to Convene Meeting

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

11.2

Notice of Meetings

(a)

At least 21 days’ notice of any meeting shall be given to the Debentureholders in the manner provided in Section 12.2 and a copy of such notice shall be sent by

post to the Debenture Trustee, unless the meeting has been called by it. Such notice shall state the time when and the place where the meeting is to be held and shall state briefly the general nature of the business to be transacted thereat and it shall not be necessary for any such notice to set out the terms of any resolution to be proposed or any of the provisions of this Article. The accidental omission to give notice of a meeting to any holder of Debentures shall not invalidate any resolution passed at any such meeting. A holder may waive notice of a meeting either before or after the meeting.

(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 11.5, especially affects the rights of holders of Debentures of one or more series in a manner or to an extent differing in any material way from that in or to which the rights of holders of Debentures of any other series are affected (determined as provided in Sections 11.2(c) and (d), then:

(i)

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

(ii)

the holders of Debentures of an especially affected series shall not be bound by any action taken at a Serial Meeting or by instrument in writing under Section 11.5 unless in addition to compliance with the other provisions of this Article 11:

(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 11 as to quorum at adjourned meetings; and (II) the resolution is passed by the affirmative vote of the holders of more than 50% (or in the case of an Extraordinary Resolution not less than 66²⁄₃%) of the principal amount of the Debentures of such series then outstanding voted on the resolution; or

(B)

in the case of action taken or power exercised by instrument in writing under Section 11.15, such instrument is signed in one or more counterparts by the holders of not less than 66²⁄₃% in principal amount of the Debentures of such series then outstanding.

(c)

Subject to Section 11.2(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 11.15, 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 Debenture Trustee and the Company 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;

(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 11.2 or Sections 11.4, 11.12 and 11.15;

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

11.3

Chairman

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

11.4

Quorum

Subject to the provisions of Section 11.12, at any meeting of the Debentureholders a quorum shall consist of Debentureholders present in person or by proxy and representing at least 25% in principal amount of the outstanding Debentures and, if the meeting is a Serial Meeting, at least 25% of the Debentures then outstanding of each especially affected series. If a quorum of the Debentureholders shall not be present within 30 minutes from the time fixed for holding any meeting, the meeting, if summoned by the Debentureholders or pursuant to a request of the Debentureholders, shall be dissolved, but in any other case the meeting shall be adjourned to the same day in the next week (unless such day is not a Business Day in which case it shall be adjourned to the next following Business Day thereafter) at the same time and place and no notice shall be required to be given in respect of such adjourned meeting. At the adjourned meeting, the Debentureholders present in person or by proxy shall, subject to the provisions of Section 11.12, constitute a quorum and may transact the business for which the meeting was originally convened notwithstanding that they may not represent 25% of the principal amount of the outstanding Debentures or of the Debentures then outstanding of each especially affected

series. Any business may be brought before or dealt with at an adjourned meeting which might have been brought before or dealt with at the original meeting in accordance with the notice calling the same. No business shall be transacted at any meeting unless the required quorum be present at the commencement of business.

11.5

Power to Adjourn

The chairman of any meeting at which a quorum of the Debentureholders is present may, with the consent of the holders of a majority in principal amount of the Debentures represented thereat, adjourn any such meeting and no notice of such adjournment need be given except such notice, if any, as the meeting may prescribe.

11.6

Show of Hands

Every question submitted to a meeting shall, subject to Section 11.7, be decided in the first place by a majority of the votes given on a show of hands except that votes on Extraordinary Resolutions shall be given in the manner hereinafter provided. At any such meeting, unless a poll is duly demanded as herein provided, a declaration by the chairman that a resolution has been carried or carried unanimously or by a particular majority or lost or not carried by a particular majority shall be conclusive evidence of the fact. The chairman of any meeting shall be entitled, both on a show of hands and on a poll, to vote in respect of the Debentures, if any, held by him.

11.7

Poll

On every Extraordinary Resolution, and on any other question submitted to a meeting when demanded by the chairman or by one or more Debentureholders or proxies for Debentureholders, a poll shall be taken in such manner and either at once or after an adjournment as the chairman shall direct. Questions other than Extraordinary Resolutions shall, if a poll be taken, be decided by the votes of the holders of a majority in principal amount of the Debentures and of each especially affected series, if applicable, represented at the meeting and voted on the poll.

11.8

Voting

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

11.9

Proxies

A Debentureholder may be present and vote at any meeting of Debentureholders by an authorized representative. The Company (in case it convenes the meeting) or the Debenture 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 Debenture Trustee, the Company or the Debentureholder convening the meeting, as the case may be, may, in the notice convening the meeting, direct and the time, if any, before the holding of the meeting or any adjournment thereof by which the same must be deposited; and

(c)

the deposit of instruments appointing proxies at some approved place or places other than the place at which the meeting is to be held and enabling particulars of such instruments appointing proxies to be mailed, faxed or sent by other electronic means before the meeting to the Company or to the Debenture 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.

11.10

Persons Entitled to Attend Meetings

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

11.11

Powers Exercisable by Extraordinary Resolution

In addition to the powers conferred upon them by any other provisions of this Indenture or by law, a meeting of the Debentureholders shall have the following powers exercisable from time to time by Extraordinary Resolution:

(b)

power to sanction any modification, abrogation, alteration, compromise or arrangement of the rights of the Debentureholders or the Debenture Trustee against the Company, or against its property, whether such rights arise under this Indenture or the Debentures or otherwise, subject to the written consent of the Debenture Trustee;

(c)

power to assent to any modification of or change in or addition to or omission from the provisions contained in this Indenture or any Debenture which shall be agreed to by the Company and to authorize the Debenture Trustee to concur in and execute any indenture supplemental hereto embodying any modification, change, addition or omission;

(d)

power to sanction any scheme for the reconstruction, reorganization or recapitalization of the Company or for the consolidation, amalgamation or merger of the Company with any other Person or for the sale, leasing, transfer or other disposition of all or substantially all of the undertaking, property and assets of the Company or any part thereof, provided that no such sanction shall be necessary in respect of any such transaction if the provisions of Section 10.1 shall have been complied with;

(e)

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

(f)

power to waive, and direct the Debenture Trustee to waive, any default hereunder and/or cancel any declaration made by the Debenture Trustee pursuant to Section 8.1 either unconditionally or upon any condition specified in such Extraordinary Resolution;

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

(k)

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

power to amend, alter or repeal any Extraordinary Resolution previously passed or sanctioned by the Debentureholders or by any committee appointed pursuant to Section 11.11(j).

11.12

Meaning of “Extraordinary Resolution”

If, at any such meeting, the holders of not less than 25% of the principal amount of the Debentures then outstanding and, if the meeting is a Serial Meeting, 25% of the principal amount of the Debentures then outstanding of each especially affected series, in each case are not present in person or by proxy within 30 minutes after the time appointed for the meeting, then the meeting, if convened by or on the requisition of Debentureholders, shall be dissolved but in any other case it shall stand adjourned to such date, being not less than 14 nor more than 60 days later, and to such place and time as may be appointed by the chairman. Not less than 10 days’ notice shall be given of the time and place of such adjourned meeting in the manner provided in Section 12.2.

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 11.15, does not adversely affect the rights of the holders of Debentures of one or more series, the provisions of this Article 11 shall apply as if the Debentures of such series were not outstanding and no notice of any such meeting need be given to the holders of Debentures of such series.

CONCERNING THE DEBENTURE TRUSTEE

13.1

No Conflict of Interest

The Debenture Trustee represents to the Company 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 Debenture Trustee as a fiduciary hereunder but if, notwithstanding the provisions of this Section 13.1, 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 Debenture 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 13.2.

13.2

Replacement of Debenture Trustee

The Debenture Trustee may resign its trust and be discharged from all further duties and liabilities hereunder by giving to the Company 60 days’ notice in writing or such shorter notice as the Company may accept as sufficient. In the event of the Debenture Trustee resigning or being removed or being dissolved, becoming bankrupt, going into liquidation or otherwise becoming incapable of acting hereunder, the Company shall forthwith appoint a new Debenture Trustee unless a new Debenture Trustee has already been appointed by the Debentureholders. Failing such appointment by the Company, the retiring Debenture Trustee or any Debentureholder may apply to a Judge of the Ontario Superior Court of Justice in the judicial district of Toronto, at the Company’s expense, on such notice as such Judge may direct, for the appointment of a new Debenture Trustee but any new Debenture Trustee so appointed by the Company or by the Court shall be subject to removal as aforesaid by the Debentureholders and the appointment of such new Debenture Trustee shall be effective only upon such new Debenture Trustee becoming bound by this Indenture. Any new Debenture Trustee appointed under any provision of this Section 13.2 shall be a corporation authorized to carry on the business of a trust company in all of the Provinces and Territories of Canada. On any new appointment the new Debenture Trustee shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Debenture Trustee.

Any company into which the Debenture Trustee may be merged or, with or to which it may be consolidated, amalgamated or sold, or any company resulting from any merger, consolidation, sale or amalgamation to which the Debenture Trustee shall be a party, or any company

succeeding to the corporate trust business of the Debenture Trustee shall be the successor trustee under this Indenture without the execution of any instrument or any further act. Nevertheless, upon the written request of the successor Debenture Trustee or of the Company, the Debenture Trustee ceasing to act shall execute and deliver an instrument assigning and transferring to such successor Debenture Trustee, upon the trusts herein expressed, all the rights, powers and trusts of the Debenture Trustee so ceasing to act, and shall duly assign, transfer and deliver all property and money held by such Debenture Trustee to the successor Debenture Trustee so appointed in its place. Should any deed, conveyance or instrument in writing from the Company be required by any new Debenture Trustee for more fully and certainly vesting in and confirming to it such estates, properties, rights, powers and trusts, then any and all such deeds, conveyances and instruments in writing shall on request of said new Debenture Trustee, be made, executed, acknowledged and delivered by the Company.

13.3

Duties of Debenture Trustee

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

13.4

Reliance Upon Declarations, Opinions, etc.

In the exercise of its rights, duties and obligations hereunder the Debenture 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 Debenture Trustee to be furnished to it in the exercise of its rights and duties hereunder, if the Debenture Trustee examines such statutory declarations, opinions, reports or certificates and determines that they comply with Section 13.5, if applicable, and with any other applicable requirements of this Indenture. The Debenture Trustee may nevertheless, in its discretion, require further proof in cases where it deems further proof desirable. Without restricting the foregoing, the Debenture Trustee may rely on an opinion of Counsel satisfactory to the Debenture Trustee notwithstanding that it is delivered by a solicitor or firm which acts as solicitors for the Company.

13.5

Evidence and Authority to Debenture Trustee, Opinions, etc.

The Company shall furnish to the Debenture Trustee evidence of compliance with the conditions precedent provided for in this Indenture relating to any action or step required or permitted to be taken by the Company or the Debenture 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 Debenture Trustee at the request of or on the application of the Company, forthwith if and when (a) such evidence is required by any other Section of this Indenture to be furnished to the Debenture Trustee in accordance with the terms of this Section 13.5, or (b) the Debenture Trustee, in the exercise of its rights and duties under this Indenture, gives the Company written notice requiring it to furnish such evidence in relation to any particular action or obligation specified in such notice.

Such evidence shall consist of:

(a)

a Certificate of the Company, stating that any such condition precedent has been complied with in accordance with the terms of this Indenture;

(b)

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

(c)

in the case of any such condition precedent compliance with which is subject to review or examination by auditors or accountants, an opinion or report of the Auditors of the Company whom the Debenture 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 certificates and delivery of Debentures and the satisfaction and discharge of this Indenture, and except as otherwise specifically provided herein, such evidence may consist of a report or opinion of any solicitor, auditor, accountant, engineer or appraiser or any other person whose qualifications give authority to a statement made by him, provided that if such report or opinion is furnished by a director, officer or employee of the Company it shall be in the form of a statutory declaration. Such evidence shall be, so far as appropriate, in accordance with the immediately preceding paragraph of this Section.

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

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

13.6

Debenture Trustee May Rely on Certificate of the Company

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

13.7

Experts, Advisers and Agents

The Debenture 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 Debenture Trustee or by the Company, 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, payable by the Company in accordance with Section 13.19(a); 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 determination and discharge of its duties hereunder and in the management of the trusts hereof and any solicitors employed or consulted by the Debenture Trustee may, but need not be, solicitors for the Company. The Debenture Trustee shall not be liable for the acts of any such agent or assistants provided that the Debenture Trustee has satisfied its standard of care in Section 13.3 hereof in selecting such agents or assistants.

13.8

Debenture Trustee May Deal in Debentures

Subject to Sections 13.1 and 13.3, the Debenture Trustee may, in its personal or other capacity, buy, sell, lend upon and deal in the Debentures and generally contract and enter into financial transactions with the Company or otherwise, without being liable to account for any profits made thereby.

13.9

Investment of Moneys Held by Debenture Trustee

Upon receipt of a written direction from the Company, the Debenture Trustee shall invest the funds in its name in accordance with such direction.

which banks are not open for business in Toronto, Ontario.

In the event that the Debenture Trustee does not receive a direction or only a partial direction, the Debenture Trustee may hold cash balances constituting part or all of the funds and may, but need not deposit such balances in an account at a Schedule I Canadian chartered bank or an Affiliate thereof. The Debenture Trustee shall not be liable to account for any profit to any parties to this Indenture or to any other person or entity other than at a rate, if any, established from time to time by the Debenture Trustee with the Company.

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

13.13

Debenture Trustee Not Required to Give Security

The Debenture 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.

13.14

Debenture Trustee Not Bound to Act on Company’s Request

13.15

Debenture Trustee Not Bound to Act

The Debenture Trustee shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Debenture Trustee, in its sole judgment, determines that such act might cause it to be in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline. Further, should the Debenture Trustee, in its sole judgment, determine at any time that its acting under this Indenture has resulted in its being in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline, then it shall have the right to resign on 10 days’ written notice to the Company, notwithstanding the provisions of Section 13.2 of this Indenture, provided that:

(a)

the Debenture Trustee’s written notice shall describe the circumstances of such non-compliance; and

The Debenture Trustee shall be protected in acting and relying upon any written notice, request, waiver, consent, certificate, receipt, statutory declaration, affidavit or other paper or document furnished to it, not only as to its due execution and the validity and the effectiveness of its provisions but also as to the truth and acceptability of any information therein contained which it in good faith believes to be genuine and what it purports to be.

13.17

Conditions Precedent to Debenture Trustee’s Obligations to Act Hereunder

The obligation of the Debenture Trustee to commence or continue any act, action or proceeding for the purpose of enforcing the rights of the Debenture Trustee and of the Debentureholders

hereunder shall be conditional upon the Debentureholders furnishing when required by notice in writing by the Debenture Trustee, sufficient funds to commence or continue such act, action or proceeding and indemnity reasonably satisfactory to the Debenture Trustee to protect and hold harmless the Debenture 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 Debenture 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 Debenture 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 Debenture Trustee and in the absence of any such notice the Debenture Trustee may for all purposes of the Indenture conclusively assume that not default has been made in the observance or performance of any of the representation, warranties, covenants, agreements or conditions contained herein. Any such notice shall in no way limit any discretion herein given the Debenture Trustee to determine whether or not the Debenture Trustee shall take action with respect to any default.

None of the provisions contained in this Indenture shall require the Debenture 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 and funded as aforesaid.

The Debenture 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 Debenture Trustee the Debentures held by them for which Debentures the Debenture Trustee shall issue receipts.

The Company shall pay to the Debenture Trustee from time to time compensation for its services hereunder as agreed separately by the Company and the Debenture Trustee, and shall pay or reimburse the Debenture Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Debenture 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 Debenture Trustee under this Indenture shall be finally and fully performed. The

Debenture Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust.

(b)

The Company hereby indemnifies and saves harmless the Debenture Trustee and its directors, officers, employees and agents (collectively, the “Indemnified Parties” and each an “Indemnified Party”) from and against any and all loss, damages, charges, expenses, claims, demands, actions or liability whatsoever which may be brought against an Indemnified Party 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 negligent failure to act, or the wilful misconduct or bad faith of an Indemnified Party. An Indemnified Party shall notify the Company promptly of any claim for which it may seek indemnity. The Company shall defend the claim and the Indemnified Party shall co-operate in the defence. An Indemnified Party may have separate Counsel and the Company shall pay the reasonable fees and expenses of such Counsel.

This indemnity shall survive the resignation or removal of the Debenture Trustee and the termination or discharge of this Indenture.

(c)

The Company need not reimburse any expense or indemnify against any loss or liability incurred by the Debenture Trustee through negligence, wilful misconduct or bad faith.

13.20

Acceptance of Trust

The Debenture 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.

13.21

Withholding Obligation

For greater certainty, the Debenture Trustee shall, as directed by the Company, withhold, from any payment made to a holder of a Debenture pursuant to the terms of this Indenture, the amount of any applicable withholding taxes required to be withheld in respect of such payment, and the Debenture Trustee shall remit such withheld amounts to the appropriate governmental authority, as and when required. For the purposes of determining the appropriate withholdings to be made from any payment to be made to a holder of a Debenture, the Company and the Debenture Trustee agree to co-operate and to provide each other with any relevant information they have with respect to the holders of the Debentures.

13.22

Protection of the Debenture Trustee

The Debenture Trustee shall not be bound to give any notice or to do or take any act, action or proceeding in virtue of the powers conferred on it hereby unless and until it shall be required so to do under the terms hereof; nor, subject to any default or Event of Default which may be known by the Debenture Trustee, shall the Debenture Trustee be required to take notice of any default or Event of Default hereunder, unless and until notified in writing of such default or

Event of Default, which notice shall distinctly specify the default or Event of Default desired to be brought to the attention of the Debenture Trustee, and in the absence of such notice, the Debenture Trustee may for all purposes of this Indenture conclusively assume that the Company is not in default hereunder and that no default has been made with respect to the payment of principal of, premium, if any, or interest on Debentures or in the observance or performance of any of the covenants, agreements or conditions contained herein. Any such notice shall in no way limit any discretion herein given to the Debenture Trustee to determine whether or not the Debenture Trustee shall take action with respect to any default or Event of Default.

The Company shall provide to the Debenture Trustee an incumbency certificate setting out the names and sample signatures of persons authorized to give instructions to the Debenture Trustee hereunder. The Debenture Trustee shall be entitled to rely on such certificate until a revised certificate is provided to it hereunder. The Debenture Trustee shall be entitled to refuse to act upon any instructions given by a party which are signed by any person other than a person described in the incumbency certificate provided to it pursuant to this Section 13.22.

The Debenture Trustee shall not be liable for any consequential, punitive or special damages.

The Debenture Trustee shall not incur any liability for not performing any act or fulfilling any duty, obligation or responsibility hereunder by reason of any occurrence beyond the control of the Debenture Trustee (including but not limited to any act or provision of any present or future law or regulation or governmental authority, any act of God or war).

The Debenture Trustee shall be entitled to treat a facsimile, pdf or e-mail communication or communication by other similar electronic means in a form satisfactory to the Debenture Trustee (“Electronic Methods”) from a person purporting to be (and whom such Debenture Trustee, acting reasonably, believes in good faith to be) the authorized representative of the Company, as sufficient instructions and authority of the Company for the Debenture Trustee to act and shall have no duty to verify or confirm that person is so authorized. The Debenture Trustee shall have no liability for any losses, liabilities, costs or expenses incurred by it as a result of such reliance upon or compliance with such instructions or directions. The Company agrees: (i) to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Debenture Trustee, including without limitation the risk of the Debenture Trustee acting on unauthorized instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting instructions to the Debenture Trustee and that there may be more secure methods of transmitting instructions than the method(s) selected by the Company; and (iii) that the security procedures (if any) to be followed in connection with its transmission of instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances.
