In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

Any certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous.  Any such certificate or Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Company stating that the information with respect to such factual matters is in the possession of the Company, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

Section 1.4     Acts Of Holders; Record Dates

(a)   Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company.  Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing

11

such instrument or instruments.  Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 6.1) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section.

(b)   The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof.  Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority.  The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee reasonably deems sufficient.

(c)   The Company may, in the circumstances permitted by the Trust Indenture Act, fix any day as the record date for the purpose of determining the Holders entitled to give or take any request, demand, authorization, direction, notice, consent, waiver or other action, or to vote on any action, authorized or permitted to be given or taken by Holders.  If not set by the Company prior to the first solicitation of a Holder made by any Person in respect of any such action, or, in the case of any such vote, prior to such vote, the record date for any such action or vote shall be the 30th day (or, if later, the date of the most recent list of Holders required to be provided pursuant to Section 10.8) prior to such first solicitation or vote, as the case may be.  With regard to any record date, only the Holders on such date (or their duly designated proxies) shall be entitled to give or take, or vote on, the relevant action.

(d)   The ownership of Securities shall be proved by the Security Register.

(e)   Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

Section 1.5     Notices, Etc., To Trustee And Company

Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with:

12

(a)   the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing (which may be via facsimile) to or with the Trustee at its Corporate Trust Office; or

(b)   the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it at the address of its principal office specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company, Attention:  General Counsel.

The Trustee shall have the right, but shall not be required, to rely upon and comply with instructions and directions sent by e-mail, facsimile and other similar unsecured electronic methods by persons believed by the Trustee to be authorized to give instructions and directions on behalf of the Company.  The Trustee shall have no duty or obligation to verify or confirm that the person who sent such instructions or directions is, in fact, a person authorized to give instructions or directions on behalf of the Company; and the Trustee shall have no liability for any losses, liabilities, costs or expenses incurred or sustained by the Company as a result of such reliance upon or compliance with such instructions or directions.  The Company agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized instructions, and the risk of interception and misuse by third parties.

Section 1.6     Notice To Holders; Waiver

Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at such Holder's address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice.  In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders.  Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice.  Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

Section 1.7     Conflict With Trust Indenture Act

If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be a part of and govern this Indenture, the latter provision shall control.  If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

The Company irrevocably submits to the nonexclusive jurisdiction of any New York State or Federal court sitting in the Borough of Manhattan, The City of New York over any suit, action or proceeding arising out of or relating to this Indenture or any Security.  The Company irrevocably waives, to the fullest extent permitted by law, any objection which it may have to the laying of the venue of any such suit, action or proceeding brought in such a court and any claim that any such suit, action or proceeding brought in such a court has been brought in any inconvenient forum.  The Company agrees that final judgment in any such suit, action or proceeding brought in such a court shall be conclusive and binding upon the Company and may be enforced in the courts of Canada (or any other courts to the jurisdiction of which the Company is subject) by a suit upon such judgment, provided that service of process is effected upon the Company in the manner specified in the following paragraph or as otherwise permitted by law; provided, however, that the Company does not waive, and the foregoing provisions of this sentence shall not constitute or be deemed to constitute a waiver of, (i) any right to appeal any such judgment, to seek any stay or otherwise to seek reconsideration or review of any such judgment or (ii) any stay of execution or levy pending an appeal from, or a suit, action or proceeding for reconsideration or review of, any such judgment.

As long as any of the Securities remain outstanding, the Company will at all times have an authorized agent in the Borough of Manhattan, The City of New York upon whom process may be served in any legal action or proceeding arising out of or relating to the Indenture or any Security.  Service of process upon such agent and written notice of such service mailed or delivered to the Company shall to the extent permitted by law be deemed in every respect effective service of process upon the Company in any such legal action or proceeding.  The Company hereby appoints CT Corporation as its agent for such purpose, and covenants and agrees that service of process in any such legal action or proceeding may be made upon it at the office of such agent at 1133 Avenue of the Xxxxxxxx, 00xx Xxxxx, Xxx Xxxx, XX, 00000 (or at such other address in the Borough of Manhattan, The City of New York, as the Company may designate by written notice to the Trustee).

Section 1.19    Conversion of Currency

(a)   The Company covenants and agrees that the following provisions shall apply to conversion of currency in the case of the Securities and this Indenture:

(i)              If for the purposes of obtaining judgment in, or enforcing the judgment of, any court in any country, it becomes necessary to convert into any other currency (the "Judgment Currency") an amount due or contingently due under the Securities and this Indenture (the "Required Currency"), then the conversion shall be made at the rate of exchange prevailing on the Business Day before the day on which a final judgment which is not appealable or is not appealed is given or the order of enforcement is made, as the case may be (unless a court shall otherwise determine).

16

(ii)              If there is a change in the rate of exchange prevailing between the Business Day before the day on which the judgment referred to in (i) above is given or an order of enforcement is made, as the case may be (or such other date as a court shall determine), and the date of receipt of the amount due, the Company shall pay such additional (or, as the case may be, such lesser) amount, if any, as may be necessary so that the amount paid in the Judgment Currency when converted at the rate of exchange prevailing on the date of receipt will produce the amount in the Required Currency originally due.

(b)   In the event of the winding-up of the Company at any time while any amount or damages owing under the Securities and this Indenture, or any judgment or order rendered in respect thereof, shall remain outstanding, the Company shall indemnify and hold the Holders of Securities and the Trustee harmless against any deficiency arising or resulting from any variation in rates of exchange between (1) the date as of which the equivalent of the amount in the Required Currency (other than under this Section 1.19(b), is calculated for the purposes of such winding-up and (2) the final date for the filing of proofs of claim in such winding-up.  For the purpose of this Section 1.19(b) the final date for the filing of proofs of claim in the winding-up of the Company shall be the date fixed by the liquidator or otherwise in accordance with the relevant provisions of applicable law as being the latest practicable date as at which liabilities of the Company may be ascertained for such winding-up prior to payment by the liquidator or otherwise in respect thereto.

(c)   The obligations contained in Section 1.19(a)(ii) and (b) of this Section shall constitute separate and independent obligations of the Company from its other obligations under the Securities and this Indenture, shall give rise to separate and independent causes of action against the Company, shall apply irrespective of any waiver or extension granted by any Holder or Trustee from time to time and shall continue in full force and effect notwithstanding any judgment or order or the filing of any proof of claim in the winding-up of the Company for a liquidated sum in respect of amounts due hereunder (other than under Section 1.19(b) above) or under any such judgment or order.  Any such deficiency as aforesaid shall be deemed to constitute a loss suffered by the Holders or the Trustee, as the case may be, and no proof or evidence of any actual loss shall be required by the Company or the applicable liquidator.  In the case of Subsection (b) above, the amount of such deficiency shall not be deemed to be reduced by any variation in rates of exchange occurring between the said final date and the date of any liquidating distribution.

(d)   The term "Rate(s) of Exchange" shall mean the Bank of Canada noon rate for purchases on the relevant date of the Required Currency with the Judgment Currency, as reported by Telerate on screen 3194 (or such other means of reporting the Bank of Canada noon rate as may be agreed upon by each of the parties to this Indenture) and includes any premiums and costs of exchange payable.

Authorized Signatory

Section 2.3     Form Of Reverse Of Security

This Security is one of a duly authorized issue of Securities of the Company, designated as its 4.50% Convertible Senior Notes due 2015 (herein called the "Securities"), all issued or to be issued under and pursuant to an Indenture dated as of November 3, 2010 (herein called the "Indenture"), between the Company and The Bank of New York Mellon (herein called the "Trustee"), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities.  Terms used herein which are defined in the Indenture have the meanings assigned to them in the Indenture.

The indebtedness evidenced by the Securities is unsecured and unsubordinated indebtedness of the Company and ranks equally with the Company's other unsecured and unsubordinated indebtedness.

Interest. The Company, promises to pay interest on the principal amount of this Security at the rate of 4.50% per annum.  The Company will pay interest semiannually on June 15 and December 15 of each year commencing on June 15, 2011.

Interest will be paid to the person in whose name a Security is registered at the close of business on or, as the case may be, immediately preceding the relevant interest payment date. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

The Holder of this Security after 5:00 p.m., New York City time, on a Regular Record Date shall be entitled to receive interest on this Security on the corresponding interest payment date. The Holder of this Security after 5:00 p.m., New York City time, on a Regular Record Date will receive payment of interest payable on the corresponding interest payment date notwithstanding the conversion of this Security at any time after the close of business on such Regular Record Date. If this Security is surrendered for conversion during the period after 5:00 p.m., New York City time, on any Regular Record Date to 9:00 a.m., New York City time, on the corresponding interest payment date, it must be accompanied by payment of an amount equal to the interest that the Holder is to receive on the Securities. Notwithstanding the foregoing, no such payment of interest need be made by any converting Holder (i) if the Company has specified a Redemption Date that is after a

20

Regular Record Date and on or prior to the corresponding interest payment date, (ii) if the Company has specified a Fundamental Change Purchase Date during such period, or (iii) to the extent of any overdue interest existing at the time of conversion of such Security. Except where this Security is surrendered for conversion and must be accompanied by payment as described above, no interest thereon will be payable by the Company on any interest payment date subsequent to the date of conversion, and delivery of the cash and Common Shares, if applicable, pursuant to Article 13 of the Indenture, together with any cash payment for any fractional share, upon conversion will be deemed to satisfy the Company's obligation to pay the principal amount of the Securities and accrued and unpaid interest, if any, to, but not including, the related Conversion Date.

Method of Payment.  By no later than 10:00 a.m. (New York City time) on the date on which any principal of or interest on any Security is due and payable, the Company shall deposit with the Paying Agent money sufficient to pay such amount.  The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts.  Payments in respect of Securities represented by a Global Security (including principal and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company.  The Company will pay principal of Definitive Securities at the office or agency designated by the Company in the Borough of Manhattan, The City of New York.  Interest on Definitive Securities will be payable (i) to Holders having an aggregate principal amount of $5,000,000 or less, by check mailed to the Holders of these Securities and (ii) to Holders having an aggregate principal amount of more than $5,000,000, either by check mailed to each Holder or, upon application by a Holder to the Registrar not later than the relevant Record Date, by wire transfer in immediately available funds to that Holder's account within the United States, which application shall remain in effect until the Holder notifies, in writing, the Registrar to the contrary.

Additional Amounts.  The Company shall pay to the Holders such Additional Amounts as may become payable under Section 10.10 of the Indenture.

Redemption For Tax Reasons.  The Company may, at its option, redeem the Securities, in whole but not in part, for an amount equal to 100% of the Principal Amount of the Securities, plus accrued and unpaid interest (including Additional Amounts, if any), to, but excluding, the Redemption Date (the "Redemption Price"), if the Company has become or would become obligated to pay to the Holders Additional Amounts (which are more than a de minimis amount) as a result of any amendment or change occurring after November 3, 2010 in the laws or any regulations of Canada or any Canadian political subdivision or taxing authority, or any change occurring after November 3, 2010 in the interpretation or application of any such laws or regulations by any legislative body, court, governmental agency, taxing authority or regulatory authority (including the enactment of any legislation and the publication of any judicial decision or regulatory or administrative determination); provided the Company cannot avoid these obligations by taking reasonable measures available to it and that it delivers to the Trustee an opinion of Canadian legal counsel specializing in taxation and an Officers' Certificate attesting to such change and obligation to pay Additional Amounts.  The Company will not and will not cause any Paying Agent or

21

the Trustee to deduct from such Redemption Price any amounts on account of, or in respect of, any Canadian Taxes other than Excluded Taxes (except in respect of certain Excluded Holders).  In such event, the Company will give the Trustee and the Holders of the Securities not less than 30 days' nor more than 60 days' notice of this redemption, except that (i) the Company will not give notice of redemption earlier than 60 days prior to the earliest date on or from which it would be obligated to pay any such Additional Amounts, and (ii) at the time the Company gives the notice, the circumstances creating its obligation to pay such Additional Amounts remain in effect.

Upon receiving such notice of redemption, each Holder who does not wish to have the Company redeem its Securities pursuant to Article 11 of the Indenture can elect to (i) convert its Securities pursuant to Article 13 of the Indenture or (ii) not have its Securities redeemed, provided that no Additional Amounts will be payable on any payment of interest or principal with respect to the Securities after such Redemption Date.  All future payments will be subject to the deduction or withholding of any Canadian Taxes required to be deducted or withheld.

Where no such election is made, the Holder will have its Securities redeemed without any further action.  If a Holder does not elect to convert its Securities pursuant to Article 13 of the Indenture but wishes to elect to not have its Securities redeemed, such Holder must deliver to the Company (if the Company is acting as its own Paying Agent), or to a Paying Agent designated by the Company for such purpose in the notice of redemption, a written Notice of Election (the "Notice of Election") on the back of this Security, or any other form of written notice substantially similar to the Notice of Election, in each case, duly completed and signed, so as to be received by the Paying Agent no later than the close of business on a Business Day at least five Business Days prior to the Redemption Date.

A Holder may withdraw any Notice of Election by delivering to the Company (if the Company is acting as its own Paying Agent), or to a Paying Agent designated by the Company in the notice of redemption, a written notice of withdrawal prior to the close of business on the Business Day prior to the Redemption Date.

If cash sufficient to pay the Redemption Price of all Securities (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent prior to 10:00 a.m., New York City time, on the Redemption Date, then on such Redemption Date, interest, including Additional Amounts, if any, cease to accrue on such Securities or portions thereof.

Offer to Purchase By the Company upon a Fundamental Change.  In the event of a Fundamental Change with respect to the Company at any time prior to December 15, 2015, the Company will be required to make an offer to purchase for cash (the "Fundamental Change Purchase Offer") all outstanding Securities at a purchase price equal to the Principal Amount plus accrued but unpaid interest, including Additional Amounts, if any (the "Fundamental Change Purchase Price"), up to, but excluding, the purchase date (the "Fundamental Change Purchase Date").

22

Within 30 Business Days after the occurrence of a Fundamental Change with respect to the Company, the Company shall mail to the Trustee and all Holders of the Securities at their addresses shown in the Security Register, and to beneficial owners of the Securities as may be required by applicable law, a notice (the "Fundamental Change Notice") of the occurrence of such Fundamental Change and the Fundamental Change Purchase Offer arising as a result thereof.  The Company shall be required to purchase Securities in respect of which such offer is accepted by a Holder no later than 30 Business Days after a Fundamental Change Notice has been mailed.

To accept the Fundamental Change Purchase Offer, a Holder of Securities must deliver to the Company (if it is acting as its own Paying Agent), or to a Paying Agent designated by the Company for such purpose in the Fundamental Change Purchase Notice and the Trustee, on or before the close of business on the third Business Day immediately preceding the Fundamental Change Purchase Date, (i) written notice of acceptance of the Fundamental Change Purchase Offer in the form set forth in the Fundamental Change Purchase Offer Acceptance Notice on the back of this Security ("Fundamental Change Purchase Notice"), or any other form of written notice substantially similar to the Fundamental Change Purchase Notice, in each case, duly completed and signed, with appropriate signature guarantee, and (ii) such Securities that the Holder wishes to tender for purchase by the Company pursuant to the Fundamental Change Offer, duly endorsed for transfer to the Company.

Holders have the right to withdraw any Fundamental Change Purchase Notice by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture.

Conversion.  Subject to and in compliance with the provisions of the Indenture (including without limitation the conditions of conversion of this Security set forth in Section 13.1 thereof), the Holder hereof has the right, at its option, to convert the Principal Amount hereof or any portion of such principal which is $1,000 or an integral multiple thereof, into, subject to Section 13.2 of the Indenture, Common Shares at the initial conversion rate of 83.5422 Common Shares per $1,000 Principal Amount of Securities (the "Conversion Rate") (equivalent to a Conversion Price of $11.97), subject to adjustment in certain events described in the Indenture.   Upon conversion of a Security, the Company will have the option to deliver Common Shares, cash or a combination of Common Shares and cash for the Securities surrendered, as set forth in the Indenture.  No fractional shares will be issued upon any conversion, but an adjustment and payment in cash will be made, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Securities for conversion.  The Trustee will initially act as Conversion Agent.  A Holder may convert fewer than all of such Holder's Securities so long as the Securities converted are an integral multiple of US$1,000 principal amount.

[INCLUDE IF SECURITY IS A GLOBAL SECURITY – In the event of a deposit or withdrawal of an interest in this Security, including an exchange, transfer, repurchase or conversion of this Security in part only, the Trustee, as custodian of the Depositary, shall make an adjustment on its records to reflect such deposit or withdrawal in accordance with the rules and procedures of the Depositary.]

Authorized Signatory

Section 2.5     Legend On Securities

All Securities shall bear the applicable legends set forth on the face of the form of Security in Section 2.2; provided that the Canadian legend set forth in Section 2.2 (the "Canadian Legend") shall not be required on any Security that is issued after March 4, 2011.

ARTICLE 3
THE SECURITIES

Section 3.1     Title; Amount And Issue Of Securities; Principal And Interest.

The Securities shall be known and designated as the "4.50% Convertible Senior Notes due 2015" of the Company.  The aggregate Principal Amount of Securities that may be authenticated and delivered under this Indenture is initially limited to $41,750,000, except for Securities authenticated and delivered upon registration of, transfer of, or in exchange for, or in lieu of other Securities pursuant to Sections 2.5, 3.3, 3.4, 3.6, 3.7, 3.8, 9.6, 11.5, 12.4 and 13.1, provided that Additional Securities with the same terms and with the same CUSIP numbers as the Securities issued on the date of this Indenture may be issued in an unlimited aggregate principal amount from time to time thereafter pursuant to Section 3.3; provided that such Additional Securities must be part of the same issue as the Securities issued on the date of this Indenture for U.S. federal income tax purposes.  The Principal Amount shall be payable on December 15, 2015, unless earlier converted, redeemed or purchased.

The Securities shall bear interest at a rate of 4.50% per year.  Interest on the Securities shall accrue from the Issue Date.  Interest shall be payable semiannually in arrears on June 15 and December 15, beginning June 15, 2011.  Interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.  Each rate of interest which is calculated with reference to a period (the "Deemed Interest Period") that is less than the actual number of days in the calendar year of calculation is, for the purposes of the Interest Act (Canada), equivalent to a rate based on a calendar year calculated by multiplying such number of days in the Deemed Interest Period.  The amount of interest payable for any period shorter than a full quarterly period for which interest is computed, will be computed on the basis of the actual number of days elapsed in the period.

30

The Principal Amount of Physical Securities shall be payable at the office or agency designated by the Company in the Borough of Manhattan, The City of New York initially the Corporate Trust Office at 000 Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000.  Interest (including Additional Amounts, if any) on Physical Securities shall be payable (i) to Holders having an aggregate Principal Amount of $5,000,000 or less, by check mailed to the Holders of these Securities and (ii) to Holders having an aggregate Principal Amount of more than $5,000,000, either by check mailed to each Holder or, upon application by a Holder to the Security Registrar not later than two days prior to the relevant record date, by wire transfer in immediately available funds to that Holder's account within the United States, which application shall remain in effect until the Holder notifies, in writing, the Security Registrar to the contrary.

A Holder of any Security at 5:00 p.m., New York City time, on a Regular Record Date shall be entitled to receive interest (including Additional Amounts, if any), on such Security on the corresponding Interest Payment Date.  Holders of Securities after 5:00 p.m., New York City time, on a Regular Record Date will receive payment of interest (including Additional Amounts, if any) payable on the corresponding interest payment date notwithstanding the conversion of such Securities at any time after the close of business on such Regular Record Date.  Securities surrendered for conversion during the period after 5:00 p.m., New York City time, on any Regular Record Date to 9:00 a.m., New York City time, on the corresponding interest payment date must be accompanied by payment of an amount equal to the interest (including Additional Amounts, if any) that the Holder is to receive on the Securities. Notwithstanding the foregoing, no such payment of interest (including Additional Amounts, if any) need be made by any converting Holder (i) if the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the corresponding interest payment date, (ii) if the Company has specified a Fundamental Change Purchase Date during such period, or (iii) to the extent of any overdue interest (including Additional Amounts, if any) existing at the time of conversion of such Security.  Except where Securities surrendered for conversion must be accompanied by payment as described above, no interest or Additional Amounts on converted Securities will be payable by the Company on any interest payment date subsequent to the date of conversion and delivery of the cash and Common Shares, if applicable, pursuant to Article 13 hereunder, together with any cash payment for any fractional share, upon conversion will be deemed to satisfy the Company's obligation to pay the principal amount of the Securities and accrued and unpaid interest or Additional Amounts, if any, to, but not including, the related Conversion Date.

Principal of and interest (including Additional Amounts, if any) on Global Securities shall be payable in immediately available funds to the Depository.

The Securities shall not be superior in right of payment to, and shall rank pari passu with, all other unsecured and unsubordinated indebtedness of the Company.

Section 3.2     Denominations

The Securities shall be issuable only in registered form without coupons and in denominations of $1,000 and any integral multiple of $1,000 above that amount.

31

Section 3.3     Execution, Authentication, Delivery And Dating

The Securities shall be executed on behalf of the Company by its Chairman of the Board, its Chief Executive Officer, its Chief Operating Officer, its Chief Financial Officer, one of its Vice Presidents, its Secretary or one of its Assistant Secretaries.  The signature of any of these officers on the Securities may be manual or facsimile.

Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities.  The Company Order shall specify the amount of Securities to be authenticated, and shall further specify the amount of such Securities to be issued as a Global Security or as Physical Securities.  The Trustee in accordance with such Company Order shall authenticate and deliver such Securities as in this Indenture provided and not otherwise.

Each Security shall be dated the date of its authentication.

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder.

Section 3.4     Temporary Securities

Pending the preparation of definitive Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities.

If temporary Securities are issued, the Company will cause definitive Securities to be prepared without unreasonable delay.  After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at any office or agency of the Company designated pursuant to Section 10.2, without charge to the Holder.  Upon surrender for cancellation of any one or more temporary Securities the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like Principal Amount of definitive Securities of authorized denominations.  Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities.

32

Section 3.5     Paying Agent; Registrar

The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the "Security Registrar") and an office or agency where Securities may be presented to the Paying Agent for payment.  The Company shall cause each of the Registrar and the Paying Agent to maintain an office or agency in the Borough of Manhattan, The City of New York.  The Security Registrar shall keep a register of the Securities and of their transfer and exchange (the "Securities Register").  The Company may have one or more co-registrars and one or more additional paying agents.  The term "Paying Agent" includes any additional paying agent and the term "Securities Registrar" includes any co-registrar.

The Company initially appoints the Trustee as the Paying Agent and the Security Registrar.  The Company may, however, change the Paying Agent or Security Registrar without prior notice to the Holders, and the Company may act as the Paying Agent and Security Registrar.

Section 3.6     Registration Of Transfer And Exchange; Restrictions On Transfer

(a)   Upon surrender for registration of transfer of any Security at an office or agency of the Company designated pursuant to Section 10.2 for such purpose, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of any authorized denominations and of a like aggregate Principal Amount and tenor, each such Security bearing such restrictive legends as may be required by this Indenture (including Section 2.2 and Section 2.5).

At the option of the Holder and subject to the other provisions of this Section 3.6, Securities may be exchanged for other Securities of any authorized denominations and of a like aggregate Principal Amount and tenor, upon surrender of the Securities to be exchanged at such office or agency.  Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing.

All Securities originally issued hereunder and all Securities issued upon registration of transfer or exchange or replacement thereof shall bear the Canadian Legend required by Section 2.2 and Section 2.5 until March 4, 2011.  Securities which are issued upon registration of transfer of, or in exchange for, Securities after March 4, 2011 shall not bear the Canadian Legend.

33

No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.4 and Section 9.6 not involving any transfer.

The Company shall not be required to exchange or register a transfer of any Security (i) that has been surrendered for conversion or (ii) as to which a Fundamental Change Purchase Notice has been delivered and not withdrawn, except, where such Fundamental Change Purchase Notice provides that such Security is to be purchased only in part, the Company shall be required to exchange or register a transfer of the portion thereof not to be purchased.

Section 3.7     Mutilated, Destroyed, Lost And Stolen Securities

If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of like tenor and Principal Amount and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and Principal Amount and bearing a number not contemporaneously outstanding.

34

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security.

Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Security issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 3.8     Persons Deemed Owners

Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

35

(d)   In connection with the transfer of the entire Global Security to beneficial owners pursuant to paragraph (b), the Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in the Global Security, an equal aggregate Principal Amount of Physical Securities of authorized denominations and the same tenor.

37

the Securities, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are delivered to the Trustee for cancellation.  The Company may not issue new Securities to replace Securities it has paid in full or delivered to the Trustee for cancellation.

(a)   The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner.  The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date (not less than 30 days after such notice) of the proposed payment (the "Special Interest Payment Date"), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided.  Thereupon the Trustee shall fix a record date (the "Special Record Date") for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the Special Interest Payment Date and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment.  The Trustee shall promptly notify the Company of such Special Record Date, and in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor to be given in the manner provided for in Section 12.2, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having been so given, such Defaulted Interest shall be paid on the Special Interest Payment Date to the Persons in whose names the Securities (or their respective predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b).

38

(b)   The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section 3.12, each Security delivered under this Indenture upon registration of, transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

Section 3.13    CUSIP Numbers

The Company in issuing the Securities may use "CUSIP", "ISIN" or other similar numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP", "ISIN" or other similar numbers in notices as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice and that reliance may be placed only on the other identification numbers printed on the Securities, and any such notice shall not be affected by any defect in or omission of such numbers.  The Company will promptly notify the Trustee of any change in the "CUSIP", "ISIN" or other similar numbers.

Section 5.2     Acceleration Of Maturity; Rescission And Annulment

(a)   If an Event of Default (other than those specified in Section 5.1(i) and Section 5.1(j) with respect to the Company) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate Principal Amount of the Outstanding Securities may declare the Principal Amount plus accrued and unpaid interest, including Additional Amounts, if any, on all the Outstanding Securities to be immediately due and payable, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such Principal Amount plus accrued but unpaid interest, including Additional Amounts, if any, shall become immediately due and payable.

42

Notwithstanding the foregoing, in the case of an Event of Default specified in Section 5.1(i) and Section 5.1(j) with respect to the Company, the Principal Amount plus accrued but unpaid interest, including Additional Amounts, if any, on all Outstanding Securities will ipso facto become due and payable without any declaration or other Act on the part of any Holder or the Trustee.

(b)   At any time after such a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article 5 provided, the Holders of a majority in aggregate Principal Amount of the Outstanding Securities, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if:

(i)              the Company has paid or deposited with the Trustee a sum sufficient to pay

(A)            the Principal Amount plus accrued but unpaid interest, including Additional Amounts, if any, Redemption Price or Fundamental Change Purchase Price, as applicable, on any Securities which have become due otherwise than by such declaration of acceleration, and interest on any such amounts that are overdue at the rate of 1.00% per annum from the required payment date, and

No such rescission shall affect any subsequent default or impair any right consequent thereon.

Section 5.3     Other Remedies

If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy to collect the payment of the Principal Amount plus accrued but unpaid interest, including Additional Amounts, if any, on the Securities or to enforce the performance of any provision of the Securities or this Indenture.  The Trustee may maintain a proceeding even if the Trustee does not

43

possess any of the Securities or does not produce any of the Securities in the proceeding.  A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of, or acquiescence in, the Event of Default.  No remedy is exclusive of any other remedy.  All available remedies are cumulative.

Section 5.4     Collection Of Indebtedness And Suits For Enforcement By Trustee

The Company covenants that if:

(a)   default is made in the payment of any interest on any Security when such amounts become due and payable, and such default continues for a period of 30 days, or

(b)   default is made in the payment of the Principal Amount plus accrued but unpaid interest, including Additional Amounts, if any, at the Stated Maturity thereof or in the payment of the Redemption Price or Fundamental Change Purchase Price in respect of any Security,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, and may prosecute such proceedings to judgment or final decree, and may enforce the same against the Company or any obligor upon the Debentures and collect the monies adjudged of decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Debentures, wherever situated.

Section 5.5     Trustee May File Proofs Of Claim

In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding.  In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making

44

of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section 6.7.

No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 5.6     Application Of Money Collected

Any money collected by the Trustee pursuant to this Article 5 or, after an Event of Default, any money or other property distributable in respect of the Company’s obligations under this Indenture shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money to Holders, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST:  To the payment of all amounts due the Trustee (including any predecessor trustee) under Section 6.7; and

SECOND:  To the payment of the amounts then due and unpaid on the Securities for the Principal Amount, Redemption Price, Fundamental Change Purchase Price or interest, including Additional Amounts, if any, as the case may be, in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities.

THIRD:  To the Company.

Section 5.7     Limitation On Suits

No Holder of any Security shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder (other than in the case of an Event of Default specified in Section 5.1(a) or Section 5.1(b)), unless:

(a)   such Holder has previously given written notice to the Trustee of a continuing Event of Default;

(b)   the Holders of not less than 25% in aggregate Principal Amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

(d)   the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(e)   no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate Principal Amount of the Outstanding Securities;

it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders.

Section 5.9     Restoration Of Rights And Remedies

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Section 5.10    Rights And Remedies Cumulative

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.7, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent

46

permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise.  The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 5.11    Delay Or Omission Not Waiver

No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.  Every right and remedy given by this Article 5 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 5.12    Control By Holders

The Holders of a majority in Principal Amount of the Outstanding Securities shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, provided that:

(a)   such direction shall not be in conflict with any rule of law or with this Indenture or may involve the Trustee in personal liability; and

(b)   the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

Prior to taking any action under this Indenture, the Trustee will be entitled to security or indemnification reasonably satisfactory to it against all losses and expenses caused by taking or not taking such action.

Section 5.13    Waiver Of Past Defaults

The Holders of not less than a majority in Principal Amount of the Outstanding Securities may on behalf of the Holders of all the Securities waive any past Default hereunder and its consequences, except a Default:

(a)   described in Section 5.1(a) or Section 5.1(b); or

(b)   in respect of a covenant or provision hereof which under Article 9 cannot be modified or amended without the consent of the Holder of each Outstanding Security affected.

Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

47

Section 5.14    Undertaking For Costs

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, in either case in respect of the Securities, a court may require any party litigant in such suit to file an undertaking to pay the costs of the suit, and the court may assess reasonable costs, including reasonable attorney's fees and expenses, against any party litigant in the suit having due regard to the merits and good faith of the claims or defenses made by the party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in Principal Amount of the Outstanding Securities, or to any suit instituted by any Holder for the enforcement of the payment of the Principal Amount or accrued but unpaid interest, including Additional Amounts, if any, on any Security on or after the Stated Maturity of such Security or the Redemption Price or Fundamental Change Purchase Price.

Section 5.15    Waiver Of Stay Or Extension Laws

The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay, or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

55

or filing of any paper or any further act on the part of any of the parties hereto.  In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

Section 10.10    Payment of Additional Amounts

All payments made by or on behalf of the Company under or with respect to the Securities will be made free and clear of and without withholding or deduction for, or on account of, any present or future duty, levy, impost, assessment or other governmental charge (including, without limitation, penalties, interest and other liabilities related thereto) imposed or levied by or on behalf of the Government of Canada or of any province or territory thereof or by any authority or agency therein or thereof having power to tax, including without limitation any taxes imposed under Part XIII of the Tax Act ("Canadian Taxes"), unless the Company is required by law or the interpretation or administration thereof, to withhold or deduct any amounts for, or on account of, Canadian Taxes.  If the Company is so required to withhold or deduct any amount for or on account of Canadian Taxes from any payment made under or with respect to the Securities, the Company will make such withholding or deduction and pay as additional interest such additional amounts ("Additional Amounts") as may be necessary so that the net amount received by each Holder after such withholding or deduction (including any withholding or deduction required to be made in respect of Additional Amounts) will not be less than the amount the Holder would have received if such Canadian Taxes had not been withheld or deducted and similar payment (the term "Additional Amounts" shall also include any such similar payments) will also be made by the Company to Holders (other than Excluded Holders) of Securities that are exempt from withholding but are required to pay tax directly on amounts otherwise subject to withholding; provided, however, that no Additional Amounts will be payable with respect to:

(a)   a payment made to a Holder or former Holder of Securities (an "Excluded Holder") in respect of the beneficial owner thereof:

(i)   with which the Company does not deal at arm's length (within the meaning of the Tax Act) at the time of making such payment;

65

(ii)   that is subject to such Canadian Taxes by reason of its failure to comply with any certification, identification, information, documentation or other reporting requirement if compliance is required by law, regulation, administrative practice or an applicable treaty as a precondition to exemption from, or a reduction in the rate of deduction or withholding of, such Canadian Taxes (provided that in the case of any imposition or change in any such certification, identification, information, documentation or other reporting requirement which applies generally to Holders of Securities who are not residents of Canada, at least sixty (60) days prior to the effective date of any such imposition or change, the Company shall give written notice, in the manner provided in this Indenture, to the Trustee and the Holders of the Securities then outstanding of such imposition or change, as the case may be, and provide the Trustee and such Holders with such forms or documentation, if any, as may be required to comply with such certification, identification, information, documentation, or other reporting requirement); or

(iii)   that is subject to such Canadian Taxes by reason of its carrying on business in or otherwise being connected with Canada or any province or territory thereof otherwise than by the mere holding of such Securities or the receipt of payments or exercise of any enforcement rights, thereunder; or

(b)   any estate, inheritance, gift, sales, excise, transfer, personal property or similar tax, assessment or governmental charge ("Excluded Taxes").

The Company will (1) make such withholding or deduction and (2) remit the full amount deducted or withheld to the relevant authority in accordance with applicable law.

The Company will furnish to the Trustee, within thirty (30) days after the date the payment of any Canadian Taxes is due pursuant to applicable law in respect of such Securities, certified copies of tax receipts evidencing such payment by the Company.

The Company will indemnify and hold harmless each Holder of any Securities (other than an Excluded Holder or with respect to Excluded Taxes) and upon written request reimburse each such Holder for the amount of:

(i)   any Canadian Taxes so levied or imposed and paid by such Holder as a result of payments made under or with respect to the Securities;

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

(iii)   any Canadian Taxes levied or imposed and paid by the Holder with respect to any reimbursement under clause (i) or (ii) above, but excluding any Excluded Taxes.

66

Additional Amounts will be paid in cash semi-annually on the applicable June 15 or December 15, at Maturity, on any Redemption Date, on a Conversion Date or on any Fundamental Change Purchase Date.

Whenever in this Indenture there is mentioned, in any context, the payment of principal and interest or any other amount payable under or with respect to any Security, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this Section to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

Anything in this Indenture to the contrary notwithstanding, the covenants and provisions of this Section 10.10 shall survive any termination or discharge of this Indenture, and the repayment of all or any of the Securities, and shall remain in full force and effect.

Section 10.11    Information For IRS Filings

The Company shall provide to the Trustee on a timely basis such information and documentation as the Trustee or the Holders may require with respect to the Internal Revenue Service and the Holders.

The Company may, at its option, redeem the Securities, in whole but not in part, at a redemption price equal to 100% of the Principal Amount of the Securities, plus accrued and unpaid interest (including Additional Amounts, if any), to, but excluding, the Redemption Date (the "Redemption Price"), if the Company has become or would become obligated to pay to the Holders Additional Amounts (which are more than a de minimis amount) as a result of any amendment or change occurring from November 3, 2010 onwards in the laws or any regulations of Canada or any Canadian political subdivision or taxing authority, or any change occurring from November 3, 2010 onwards in an interpretation or application of such laws or regulations by any legislative body, court, governmental agency, taxing authority or regulatory authority (including the enactment of any legislation and the publication of any judicial decision or regulatory or administrative determination); provided the Company cannot avoid these obligations by taking reasonable measures available to it and that it delivers to the Trustee an opinion of Canadian legal counsel specializing in taxation and an Officers' Certificate attesting to such change and obligation to pay Additional Amounts.  The Company will not and will not cause any Paying Agent or the Trustee to deduct from such Redemption Price any amounts on account of, or in respect

67

 of, any Canadian Taxes other than Excluded Taxes (except in respect of certain Excluded Holders).  In such event, the Company will give the Holders of the Securities not less than 30 days' nor more than 60 days' notice, and will give the Trustee not less than 45 days’ nor more than 60 days’ notice, of this redemption pursuant to Section 11.2, except that (i) the Company will not give notice of redemption earlier than 60 days prior to the earliest date on or from which it would be obligated to pay any such Additional Amounts, and (ii) at the time the Company gives the notice, the circumstances creating its obligation to pay such Additional Amounts remain in effect.

Upon receiving such notice of redemption, each Holder who does not wish to have the Company redeem its Securities pursuant to this Section 11.1 can elect to (i) convert its Securities pursuant to Article 13 or (ii) not have its Securities redeemed, provided that no Additional Amounts will be payable by the Company on any payment of interest or principal with respect to the Securities after such Redemption Date.  Securities and portions of Securities that are to be redeemed are convertible by the Holder until 5:00 p.m., New York City time, on the Business Day immediately preceding the Redemption Date.  All future payments will be subject to the deduction or withholding of any Canadian Taxes required to be deducted or withheld.

Where no such election is made, the Holder will have its Securities redeemed without any further action.  If a Holder does not elect to convert its Securities pursuant to Article 13 but wishes to elect to not have its Securities redeemed pursuant to clause (ii) of the preceding paragraph, such Holder must deliver to the Company (if the Company is acting as its own Paying Agent), or to a Paying Agent designated by the Company for such purpose in the notice of redemption, a written Notice of Election upon Tax Redemption (the "Notice of Election") on the back of the Securities, or any other form of written notice substantially similar to the Notice of Election, in each case, duly completed and signed, so as to be received by the Paying Agent no later than the Close of Business on a Business Day at least five Business Days prior to the Redemption Date.

A Holder may withdraw any Notice of Election by delivering to the Company (if the Company is acting as its own Paying Agent), or to a Paying Agent designated by the Company in the notice of redemption, a written notice of withdrawal prior to the Close of Business on the Business Day prior to the Redemption Date.

Section 11.2     Notice Of Redemption

The notice of redemption shall identify the Securities to be redeemed and shall state:

(a)   the Redemption Date;

(b)   the Redemption Price;

(c)   the then current Conversion Rate for conversion of Securities;

(d)   the name and address of the Paying Agent and Conversion Agent;

68

(e)   that Securities called for redemption may be converted at any time prior to 5:00 p.m., New York City time, on the Business Day preceding the Redemption Date;

(f)   that Holders who want to convert their Securities must satisfy the requirements set forth in Article 13;

(g)   that Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price;

(h)   that, unless the Company defaults in making payment of such Redemption Price, any interest (including Additional Amounts, if any) on Securities called for redemption will cease to accrue on and after the Redemption Date;

(i)   the CUSIP number(s) of the Securities; and

(j)   any other information the Company wants to present.

At the Company's request, the Trustee shall give the notice of redemption in the Company's name and at the Company's expense; provided, however, that the Company makes such request at least five Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to the date by which such notice of redemption must be given to Holders in accordance with this Section 11.2; provided, further, that the text of the notice of redemption shall be prepared by the Company.

Section 11.3     Effect Of Notice Of Redemption

Once notice of redemption is given, Securities called for redemption become due and payable on the Redemption Date and at the Redemption Price, except for Securities which are converted in accordance with the terms of this Indenture.  Upon surrender to the Paying Agent, such redeemed Securities shall be paid at the Redemption Price.

Section 11.4     Deposit Of Redemption Price

Prior to 10:00 a.m., New York City time, on the applicable Redemption Date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of any of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 10.3) an amount of cash (in immediately available funds if deposited on the Redemption Date) sufficient to pay the aggregate Redemption Price of all Securities or portions thereof which are to be redeemed as of such Redemption Date other than Securities or portions of Securities called for redemption which on or prior thereto have been delivered by the Company to the Trustee for cancellation or have been converted.

If the Paying Agent holds, in accordance with the terms hereof, at 10:00 a.m., New York City time, on the applicable Redemption Date, cash sufficient to pay the Redemption Price of any Securities for which notice of redemption has been given, then, on such Redemption Date, such Securities will cease to be outstanding and interest (including Additional Amounts, if

69

any), on such Securities will cease to accrue, whether or not such Securities are delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate (other than the right to receive the Redemption Price upon delivery of such Securities).

Section 11.5     Securities Redeemed In Part

Any Physical Security which is to be redeemed only in part shall be surrendered at the office of the Paying Agent and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without charge, a new Security or Securities, of any authorized denomination as requested by such Holder in aggregate Principal Amount equal to the unredeemed portion of the Security surrendered.

Section 11.6     Repayment To The Company

To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 11.4 exceeds the aggregate Redemption Price of the Securities or portions thereof which the Company is redeeming as of the Redemption Date, then, promptly after the Redemption Date, the Paying Agent shall return any such excess to the Company.

Section 11.7     Other Repurchases

The Company may, from time to time, at its option (and nothing contained in this Indenture shall limit the Company's right to), repurchase the Securities in open market purchases or negotiated transactions, without any prior notice to any Holders, provided that in exercising its right under this Section 11.7, the Company complies with all applicable federal and state securities laws.

ARTICLE 12                                

OFFER TO PURCHASE UPON A FUNDAMENTAL CHANGE

Section 12.1     Offer to Purchase Upon A Fundamental Change

(i)   General.  In the event of a Fundamental Change with respect to the Company at any time prior to December 15, 2015, the Company will be required to make an offer to purchase for cash (a "Fundamental Change Purchase Offer") on the date (the "Fundamental Change Purchase Date") that is 30 business days after the Fundamental Change Purchase Offer, all outstanding Securities in integral multiples of $1,000 principal amount at a price equal to the Principal Amount of the Securities to be purchased plus accrued but unpaid interest, including Additional Amounts, if any (the "Fundamental Change Purchase Price"), up to but excluding the Fundamental Change Purchase Date, subject to satisfaction by or on behalf of any Holder of the requirements set forth in Section 12.1(c).

70

If such purchase date is after a Record Date but on or prior to an Interest Payment Date, however, then the interest payable on such date will be paid to the Holder of record of the Securities on the relevant Record Date.

Within 30 Business Days after the occurrence of a Fundamental Change with respect to the Company, the Company shall mail to the Trustee and all Holders of the Securities at their addresses shown in the Security Register, and to beneficial owners of the Securities as may be required by applicable law, a notice (the "Fundamental Change Notice") of the occurrence of such Fundamental Change and the Fundamental Change Purchase Offer arising as a result thereof in accordance with Section 12.1(b).

A "Fundamental Change" shall be deemed to have occurred at the time after the Securities are originally issued that any of the following occurs:

(i)   a "person" or "group" within the meaning of Section 13(d) of the Exchange Act, other than the Company, any Subsidiary of the Company or any employee benefit plan of the Company or any such Subsidiary, files a Schedule TO or any schedule, form or report under the Exchange Act disclosing that such person or group has become the direct or indirect ultimate "Beneficial Owner," as defined in Rule 13d-3 under the Exchange Act, of Common Equity of the Company representing more than 50% of the voting power of the Company's Common Equity;

(ii)   consummation of any share exchange, consolidation, amalgamation, merger, statutory arrangement or other combination pursuant to which the Common Shares will be converted into cash, securities or other property or any sale, lease or other transfer in one transaction or a series of transactions of all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole, to any Person other than one of the Company's wholly-owned Subsidiaries; provided, however, that a transaction where the holders of more than 50% of all classes of the Company's Common Equity immediately prior to such transaction own, directly or indirectly, more than 50% of all classes of Common Equity of the continuing or surviving corporation or transferee immediately after such event shall not be a Fundamental Change;

(iii)   Continuing Directors cease to constitute at least a majority of the Company's Board of Directors; or

(iv)   the shareholders of the Company approve any plan or proposal for the liquidation or dissolution of the Company.

A Fundamental Change will not be deemed to have occurred, however, if at least 90% of the consideration, excluding cash payments for fractional shares, in the transaction or transactions constituting the Fundamental Change consists of common shares or American Depositary Shares that are traded or listed on, or immediately after the transaction or event will be traded or listed on a U.S. national securities exchange or the Toronto Stock Exchange.

71

(b)   Notice of Fundamental Change.  Within 30 days after the occurrence of a Fundamental Change, the Company shall mail the Fundamental Change Notice by first-class mail to the Trustee and to each Holder (and to beneficial owners as required by applicable law).  The notice shall include a form of Fundamental Change purchase notice (the "Fundamental Change Purchase Notice") to be completed by the Holder and shall state:

(i)   the events causing a Fundamental Change and the date of such Fundamental Change;

(ii)   that a Fundamental Change Purchase Offer is being made pursuant to Article 12 and that all Securities validly tendered and not withdrawn will be purchased pursuant to the terms of such Article 12;

(iii)   the date by which the Fundamental Change Purchase Notice pursuant to this Section 12.1 must be delivered to the Paying Agent in order for a Holder to accept the Fundamental Change Purchase Offer;

(iv)   the Fundamental Change Purchase Date;

(v)   the Fundamental Change Purchase Price;

(vi)   the name and address of the Paying Agent and the Conversion Agent;

(vii)   the conversion rights, if any, of the Securities;

(viii)   the Conversion Rate applicable on the Fundamental Change Purchase Date;

(ix)   that Securities as to which a Fundamental Change Purchase Notice has been given may be converted pursuant to Article 13 hereof only if the Fundamental Change Purchase Notice has been withdrawn in accordance with the terms of this Indenture;

(x)   that Securities must be surrendered to the Paying Agent for cancellation to collect payment;

(xi)   that the Fundamental Change Purchase Price for any Security as to which a Fundamental Change Purchase Notice has been duly given and not withdrawn will be paid promptly following the later of the Fundamental Change Purchase Date and the time of surrender of such Security as described in (ix);    

72

(xii)   the procedures the Holder must follow to exercise rights under this Section 12.1;

(xiii)   the procedures for withdrawing a Fundamental Change Purchase Notice; and

(xiv)   the CUSIP number of the Securities.

At the Company's request, the Trustee shall give such Fundamental Change Company Notice in the Company's name and at the Company's expense; provided, however, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company.

(c)   Fundamental Change Purchase Notice.  To accept the Fundamental Change Purchase Offer, a Holder of Securities must deliver to the Company (if the Company is acting as its own Paying Agent), or to a Paying Agent designated by the Company for such purpose in the Fundamental Change Notice and the Trustee, on or before the close of business on the third Business Day immediately preceding the Fundamental Change Purchase Date, (i) written notice of acceptance of the Fundamental Change Purchase Offer in the form set forth in the Fundamental Change Purchase Notice, or any other form of written notice substantially similar to the Fundamental Change Purchase Notice, in each case, duly completed and signed, with appropriate signature guarantee, and (ii) such Securities that the Holder wishes to tender for purchase by the Company pursuant to the Fundamental Change Purchase Offer, duly endorsed for transfer to the Company on the back of the Securities.

Such notice shall state, among other things (a) that if certificated Securities have been issued, the certificate numbers (or, if the Securities are not certificated, the notice must comply with the Depositary’s procedures); (b) the portion of the principal amount of Securities to be purchased, which must be in US$1,000 multiples; and (c) that the Securities are to be purchased by the Company pursuant to the applicable provisions of the Securities and the Indenture.

The delivery of such Security to the Paying Agent with, or at any time after delivery of, the Fundamental Change Purchase Notice (together with all necessary endorsements) at the offices of the Paying Agent shall be a condition to the receipt by the Holder of the Fundamental Change Purchase Price therefor; provided, however, that such purchase price shall be so paid pursuant to this Section 12.1 only if the Security so delivered to the Paying Agent shall conform in all respects to the description thereof set forth in the related Fundamental Change Purchase Notice.

The Company shall purchase from the Holder thereof, pursuant to this Section 12.1, a portion of a Security, so long as the Principal Amount of such portion is US$1,000 or an integral multiple thereof.  Provisions of this Indenture that apply to the repurchase of all of a Security also apply to the repurchase of such portion of such Security.

73

Any purchase by the Company contemplated pursuant to the provisions of this Section 12.1 shall be consummated by the delivery of the Fundamental Change Purchase Price to be received by the Holder promptly following the later of the Purchase Date and the time of delivery of the Security; provided, however, that if the Fundamental Change Purchase Notice is delivered after a date which is two (2) Business Days prior to the Purchase Date, such payment may be made as promptly after such Purchase Date as is practicable.

Notwithstanding anything contained herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Purchase Notice contemplated by this Section 12.1(c) shall have the right to withdraw such Fundamental Change Purchase Notice at any time prior to the close of business on the Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 12.2.

The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase Notice or written notice of withdrawal thereof.

Section 12.2     Effect Of Fundamental Change Purchase Notice

Upon receipt by the Paying Agent of the Fundamental Change Purchase Notice specified in Section 12.1(c), the Holder of the Security in respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn as specified in the following two paragraphs) thereafter be entitled to receive solely the Fundamental Change Purchase Price with respect to such Security.  Such purchase price shall be paid to such Holder, subject to receipt of funds and/or securities by the Paying Agent, promptly following the later of (x) the Purchase Date with respect to such Security (provided the conditions in Section 12.1(c) have been satisfied) and (y) the time of delivery of such Security to the Paying Agent by the Holder thereof in the manner required by Section 12.1(c).  Securities in respect of which a Fundamental Change Purchase Notice has been given by the Holder thereof may not be converted pursuant to Article 13 hereof on or after the date of the delivery of such Fundamental Change Purchase Notice unless such Fundamental Change Purchase Notice has first been validly withdrawn as specified in the following two paragraphs.

A Fundamental Change Purchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent in accordance with the procedures set forth in the Fundamental Change Company Notice at any time prior to the close of business on the Purchase Date specifying:

(i)   the Principal Amount of the Security with respect to which such notice of withdrawal is being submitted;

(ii)   the certificate number, if any, or the appropriate Depositary procedures, if applicable, of the Security in respect of which such notice of withdrawal is being submitted; and

74

(iii)   the Principal Amount, if any, of such Security which remains subject to the original Fundamental Change Purchase Notice and which has been or will be delivered for repurchase by the Company.

There shall be no purchase of any Securities pursuant to Section 12.1 if there has occurred (prior to, on or after, as the case may be, the giving, by the Holders of such Securities, of the required Fundamental Change Purchase Notice) and is continuing an Event of Default (other than an Event of Default that is cured by the payment of the Fundamental Change Purchase Price with respect to such Securities).  The Paying Agent will promptly return to the respective Holders any Securities (x) with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with this Indenture, or (y) held by it during the continuance of an Event of Default if a Responsible Officer of the Paying Agent has knowledge of an Event of Default in respect of which the Paying Agent has received written notice (other than a default in the payment of the Fundamental Change Purchase Price with respect to such Securities) in which case, upon such return, the Fundamental Change Purchase Notice with respect thereto shall be deemed to have been withdrawn.

Section 12.3     Deposit Of Fundamental Change Purchase Price

Prior to 10:00 a.m. (New York City time) on the Business Day following the Fundamental Change Purchase Date, the Company shall deposit with the Trustee or with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of any of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of cash (in immediately available funds if deposited on such Business Day) sufficient to pay the aggregate Fundamental Change Purchase Price of all the Securities or portions thereof which are to be purchased on such Fundamental Change Purchase Date.

If the Paying Agent holds, in accordance with the terms hereof, at 10:00 a.m. (New York City time) on the Business Day immediately following the applicable Fundamental Change Purchase Date, cash sufficient to pay the Fundamental Change Purchase Price of any Securities for which a Fundamental Change Purchase Notice has been tendered and not withdrawn pursuant to Section 12.2, then, immediately after such Fundamental Change Purchase Date, such Securities will cease to be outstanding, and the rights of the Holders in respect thereof shall terminate (other than the right to receive the Fundamental Change Purchase Price upon delivery of such Securities).

Section 12.4     Securities Purchased In Part

Any Security which is to be purchased only in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder's attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder in aggregate Principal Amount equal to, and in exchange for, the portion of the Principal Amount of the Security so surrendered which is not purchased.

75

Section 12.5   Covenant To Comply With Securities Laws Upon Repurchase Of Securities

In connection with any offer to repurchase Securities under Section 12.1 hereof (provided that such offer or repurchase constitutes an "issuer tender offer" for purposes of Rule 13e-4 (which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or purchase), and subject to any exemptions under applicable law, the Company shall (i) comply with Rule 13e-4 and Rule 14e-1 (or any successor provision) under the Exchange Act, (ii) file the related Schedule TO (or any successor schedule, form or report) under the Exchange Act, (iii) otherwise comply with all Federal and state securities laws so as to permit the rights and obligations under Section 12.2 to be exercised in the time and in the manner specified in Section 12.2 and (iv) comply with any Canadian laws which may then be applicable in the event of a fundamental change.

To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Article 12, the Company's compliance with such laws and regulations including the extension of the payment or notice periods contemplated by this Article, shall not in and of itself cause a breach of their obligations under this Article 13.

Section 12.6     Repayment To The Company

The Trustee and the Paying Agent shall return to the Company any cash that remain unclaimed, together with interest, if any, thereon, held by them for the payment of the Fundamental Change Purchase Price; provided, however, that to the extent that the aggregate amount of cash deposited by the Company pursuant to Section 12.3 exceeds the aggregate Fundamental Change Purchase Price of the Securities or portions thereof which the Company is obligated to purchase as of the Fundamental Change Purchase Date then the Trustee or the Paying Agent, as the case may be, shall return any such excess to the Company.

ARTICLE 13

CONVERSION

Section 13.1     Right To Convert

(a)   Subject to and upon compliance with the provisions of this Indenture, each Holder shall have the right, at such Holder's option, at any time following the Issue Date of the Securities hereunder through prior to the close of business on the business day immediately preceding the Stated Maturity to convert the Principal Amount of any such Securities, or any portion of such Principal Amount which is $1,000 or an integral multiple thereof at the Conversion Price then in effect.

(b)   Conversion Upon Specified Corporate Transactions

(i)   If the Company becomes a party to a consolidation, amalgamation, merger, binding share exchange, statutory arrangement, sale of all or substantially all of the Company's assets or other combination, in each case pursuant to which the Common Shares are converted into cash, securities, or other property, then at the effective time of the transaction, a Holder of Securities' right to convert the Securities into Common Shares will be changed into a right to convert such Securities into the kind and amount of cash, securities and other property which Holders of the Securities would have received if those Holders had converted such Securities immediately prior to the transaction (the "Reference Property").  If the transaction causes the Common Shares to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of shareholder election), the Reference Property into which the Securities shall be convertible shall be deemed to be the weighted average of the types and amounts of consideration received by the Holders of the Common Shares that affirmatively make such an election.  The Company shall not become a party to any such transaction unless its terms are consistent with the foregoing.

76

(ii)   If Holders of Securities would otherwise be entitled to receive, upon conversion of the Securities, any property (including cash) or securities that would not constitute ''Prescribed Securities'' for the purposes of clause 212(1)(b)(vii)(E) of the Income Tax Act (Canada), as it applied to the 2007 taxation year (referred to herein as ''Ineligible Consideration''), such Holders shall not be entitled to receive such Ineligible Consideration but the Company or the successor or acquirer, as the case may be, shall have the right (at the sole option of the Company or the successor or acquirer, as the case may be) to deliver either such Ineligible Consideration or Prescribed Securities for the purposes of clause 212(1)(b)(vii)(E) of the Income Tax Act (Canada), as it applied to the 2007 taxation year, with a market value equal to the market value of such Ineligible Consideration. In general, Prescribed Securities would include Common Shares and other shares which are not redeemable by the Holder within five years of the date of issuance of the Securities.  The Company shall give notice to the Holders of Securities at least 30 days prior to the effective date of such transaction in writing and by release to a business newswire stating the consideration into which the Securities will be convertible after the effective date of such transaction.  After such notice, the Company or the successor or acquirer, as the case may be, may not change the consideration to be delivered upon conversion of the Security except in accordance with any other provision of this Indenture.

(iii)   If the transaction also constitutes a Fundamental Change, the Company will be required, subject to certain conditions, to offer to purchase for cash all or a portion of a Holder's Securities in accordance with Article 12.

77

(c)   Notwithstanding the foregoing, a Security in respect of which a Holder has delivered a Fundamental Change Purchase Notice may be converted only if such Fundamental Change Repurchase Notice is withdrawn in accordance with Article 12 prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date.

(d)   Each stock certificate representing Common Shares issued upon conversion of the Securities on or before March 4, 2011 shall bear the legend in substantially the form of Exhibit B hereto.

Section 13.2     Conversion Procedure

(a)   Each Security shall be convertible at the office of the Conversion Agent.

(b)   In order to exercise the conversion privilege with respect to any Securities in certificated form, the Holder of any such Securities to be converted, in whole or in part, shall:

(i)   complete and manually sign the conversion notice provided on the back of the Security (the "Conversion Notice") or facsimile of the conversion notice and deliver such notice to a Conversion Agent;

(ii)   surrender the Security to the Conversion Agent;

(iii)   furnish appropriate endorsements and transfer documents, if required; and

(iv)   pay any transfer or similar tax, if required.

The date on which the Holder satisfies all of the requirements set forth in (i) through (iv) above is the "Conversion Date."  Such notice shall also state the name or names (with address or addresses) in which any certificate or certificates for Common Shares which shall be issuable on such conversion shall be issued.  All such Securities surrendered for conversion shall, unless the shares issuable on conversion are to be issued in the same name as the registration of such Securities, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or his duly authorized attorney.

In order to exercise the conversion privilege with respect to any interest in Securities in global form, the Holder must complete the appropriate instruction form for conversion pursuant to the Depositary's book-entry conversion program, furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or Conversion Agent, and pay the funds, if any, required by this Section 13.2 and any transfer taxes if required pursuant to Section 13.7.

78

(c)   As promptly as practicable after the later of (i) the Conversion Date (but in no event later than 5 Business Days after the Conversion Date) or (ii) the date all the calculations necessary to make such payment and delivery have been made (but in no event later than as specified in Section 13.3), subject to compliance with any restrictions on transfer if shares issuable on conversion are to be issued in a name other than that of the Holder (as if such transfer were a transfer of the Securities (or portion thereof) so converted), the Company shall issue and shall deliver to such Holder at the office of the Conversion Agent, a check or cash and a certificate or certificates for the number of full Common Shares issuable in accordance with the provisions of this Article 13, if applicable.  In case any Securities of a denomination greater than $1,000 shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the Securities so surrendered, without charge to him, new Securities in authorized denominations in an aggregate Principal Amount equal to the unconverted portion of the surrendered Securities.

Each conversion shall be deemed to have been effected as to any such Securities (or portion thereof) on the date on which the requirements set forth above in this Section 13.2 have been satisfied as to such Securities (or portion thereof), and the person in whose name any certificate or certificates for Common Shares shall be issuable upon such conversion shall be deemed to have become on said date the Holder of record of the shares represented thereby; provided, however, that in case of any such surrender on any date when the stock transfer books of the Company shall be closed, the person or persons in whose name the certificate or certificates for such shares are to be issued shall be deemed to have become the record Holder thereof for all purposes on the next day on which such stock transfer books are open, but such conversion shall be at the Conversion Price in effect on the date upon which such Securities shall be surrendered.

(d)   Upon the conversion of an interest in Global Securities, the Trustee (or other Conversion Agent appointed by the Company) shall make a notation on such Global Securities as to the reduction in the Principal Amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Securities effected through any Conversion Agent other than the Trustee.

Section 13.3     Company to deliver Common Shares, cash or combination of thereof

(a)   Upon conversion of a Security, the Company will have the option to deliver Common Shares, cash or a combination of cash and Common Shares for the Securities surrendered as set forth below.  The Trustee will initially act as Conversion Agent.  A Holder may convert fewer than all of such Holder's Securities so long as the Securities converted are an integral multiple of US$1,000 principal amount.

The Company will have the option to deliver cash in lieu of some or all of the Common Shares to be delivered upon conversion of the Securities.  The Company will give notice of its election to deliver part or all of the conversion consideration in cash to the Holder

79

converting the Securities within two Business Days of the Company's receipt of the Holder's notice of conversion.  The amount of cash to be delivered per Security will be equal to the number of Common Shares in respect of which the cash payment is being made multiplied by the average of the Daily VWAP prices of the Common Shares for the 10 trading days commencing one day after (a) the date of the Company's notice of election to deliver all or part of the conversion consideration in cash if it has not given a Redemption Notice or (b) the conversion date, in the case of conversion following notice of redemption specifying the Company's intention to deliver cash upon conversion.

If the Company elects to deliver cash in lieu of some or all of the Common Shares issuable upon conversion, it will make the payment, including delivery of the Common Shares, through the Conversion Agent, to Holders surrendering Securities no later than the fourteenth Business Day following the Conversion Date.  Otherwise, the Company will deliver the Common Shares, together with any cash payment for fractional shares, as described below, through the Conversion Agent no later than the fifth business day following the Conversion Date.

The Company may not deliver cash in lieu of any Common Shares issuable upon a Conversion Date (other than in lieu of fractional shares) if there has occurred and is continuing an Event of Default under the Indenture, other than an Event of Default that is cured by the payment of the conversion consideration.

If the Company calls Securities for redemption, a Holder of Securities may convert the Securities only until the close of business on the business day immediately preceding the Redemption Date unless the Company fails to pay the Redemption Price.  If a Holder of Securities has submitted the Securities for purchase upon a Fundamental Change, a Holder of Securities may convert the Securities only if that Holder withdraws the purchase election made by that Holder.

Upon conversion, a Holder will not receive any separate cash payment for accrued and unpaid interest and Additional Amounts, if any, unless such conversion occurs between a regular record date and the Interest Payment Date to which it relates.  The Company will not issue fractional Common Shares upon conversion of Securities.  Instead, the Company will pay cash in lieu of fractional shares based on the last reported sale price of the Common Shares on the trading day prior to the Conversion Date.

The Company's delivery to the Holder of Common Shares, cash, or a combination of cash and Common Shares, as applicable, together with any cash payment for any fractional share, into which a Security is convertible, will be deemed to satisfy the Company's obligation to pay

(i)   the principal amount of the Security; and

(ii)   accrued and unpaid interest and Additional Amounts, if any, to, but not including, the Conversion Date.

80

As a result, accrued and unpaid interest and Additional Amounts, if any, to, but not including, the Conversion Date will be deemed to be paid in full rather than cancelled, extinguished or forfeited.

(b)   Notwithstanding the preceding paragraph, if Securities are converted after 5:00 p.m., New York City time, on a regular Record Date for the payment of interest, Holders of such Securities at 5:00 p.m., New York City time, on such Record Date will receive the interest and Additional Amounts, if any, payable on such Securities on the corresponding Interest Payment Date notwithstanding the conversion.  Securities, upon surrender for conversion during the period from 5:00 p.m., New York City time, on any regular record date to 9:00 a.m.  New York City time, on the immediately following Interest Payment Date, must be accompanied by funds equal to the amount of interest and Additional Amounts, if any, payable on the Securities so converted; provided that no such payment need be made

·   if the Company has specified a Redemption Date that is after a Record Date and on or prior to the corresponding Interest Payment Date;

·   if the Company has specified a Fundamental Change Purchase Date that is after a Record Date and on or prior to the corresponding Interest Payment Date; or

·   to the extent of any overdue interest, if any overdue interest exists at the time of Conversion with respect to such Security.

If a Holder converts Securities, the Company will pay any documentary, stamp or similar issue or transfer tax due on the issue of any of its Common Shares upon the conversion, unless the tax is due because the Holder requests any shares to be issued in a name other than the Holder's name, in which case the Holder will pay that tax.

(c)   Upon conversion, Holders will not receive any separate cash payment for accrued and unpaid interest and Additional Amounts, if any, unless such conversion occurs between a Regular Record Date and the Interest Payment Date to which it relates.

(d)   The Company will not issue fractional Common Shares upon conversion of Securities.  If multiple Securities shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion shall be computed on the basis of the aggregate Principal Amount of the Securities (or specified portions thereof to the extent permitted hereby) so surrendered.  If any fractional share of stock would be issuable upon the conversion of any Securities, the Company shall make payment therefor in cash equal to the fraction of a common share otherwise issuable multiplied by the Current Market Price to the Holder of such Securities.

Section 13.4     Conversion Rate Adjustments

The Conversion Rate shall be adjusted from time to time by the Company as follows, except that the Company shall not make any adjustment if holders of Securities may participate, as a result of holding the Securities, in the transaction described without having to convert their Securities.

(a)   If the Company, at any time or from time to time while any of the Securities are outstanding, pays a dividend or make a distribution in Common Shares to all holders of its outstanding Common Shares, or if the Company subdivides or combines its Common Shares then the Conversion Rate will be adjusted based on the following formula:

where,

CR0 =       the Conversion Rate in effect immediately prior to such event

CR' =        the Conversion Rate in effect immediately after such event

OS0 =       the number of Common Shares outstanding immediately prior to such event

OS' =        the number of Common Shares outstanding immediately after such event

Such adjustment shall become effective immediately after the opening of business on the day following the Record Date for such dividend or distribution, or the date fixed for determination for such share split or share combination.  If any dividend or distribution of the type described in this Section 13.4(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate which would then be in effect if such dividend or distribution had not been declared.

(b)   If the Company, at any time or from time to time while any of the Securities are outstanding, issues to all or substantially all holders of its outstanding Common Shares certain rights or warrants to purchase Common Shares (or securities convertible into or exchangeable or exercisable for Common Shares) at a price per share (or having a conversion, exchange or exercise price per share) less than the Closing Sale Price of Common Shares on the Record Date for shareholders entitled to receive such rights and warrants, which rights or warrants are exercisable for not more than 60 days, the Conversion Rate shall be adjusted based on the following formula (provided that the Conversion Rate shall be readjusted to the extent that such rights or warrants are not exercised prior to their expiration):

82

where,

CR0 =       the Conversion Rate in effect immediately prior to such event

CR' =        the Conversion Rate in effect immediately after such event

OS0 = the number of Common Shares outstanding on the close of business on the next Business Day following such Record Date

X = the total number of Common Shares issuable pursuant to such rights

Y = the number of Common Shares equal to the aggregate offering price that the total number of shares so offered would purchase at such Closing Sale Price of Common Shares on the Record Date of such issuance determined by multiplying such total number of shares so offered by the exercise price of such rights or warrants and dividing the product so obtained by such Closing Sale Price.

Such adjustment shall become effective immediately after the opening of business on the day following the date of announcement of such issuance.

To the extent that Common Shares (or securities convertible into or exchangeable or exercisable for Common Shares) are not delivered pursuant to such rights or warrants, upon the expiration or termination of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of Common Shares (or securities convertible into or exchangeable or exercisable for Common Shares) actually delivered.  In the event that such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if the date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed.  In determining whether any rights or warrants entitle the holders to subscribe for or purchase Common Shares at less than such Closing Sale Price, and in determining the aggregate offering price of such Common Shares, there shall be taken into account any consideration received for such rights or warrants and the value of such consideration, if other than cash, to be determined in good faith by the Board of Directors of the Company.

For the purposes of this Section 13.4(b), rights or warrants distributed by the Company to all holders of its Common Shares entitling them to subscribe for or purchase shares of the Company's capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events ("Trigger Event"): (1) are deemed to be transferred with such Common Shares; (2) are not exercisable; and (3) are also issued in respect of future issuances of Common Shares, shall be deemed not to have been distributed for purposes of this Section 13.4(b) (and no adjustment to the Conversion Price under this Section 13.4(b) will be required) until the occurrence of the earliest Trigger Event,

83

whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 13.4(b). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 13.4(b) was made, (1) in the case of any such rights or warrants which shall all have been redeemed or purchased without exercise by any Holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder of Common Shares with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all applicable holders of Common Shares as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants which shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued.

(c)   If the Company, at any time or from time to time while the Securities are outstanding, distributes to all or substantially all holders of its Common Shares, Common Shares of the Company, evidences of its indebtedness or assets, including securities, but excluding:

(i)   dividends or distributions referred to in Section 13.4(a);

(ii)   rights or warrants referred to in Section 13.4(b); and

(iii)   dividends or distributions referred to in Section 13.4(d);

then the Conversion Rate shall be adjusted based on the following formula:

where,

CR0 = the Conversion Rate in effect immediately prior to such distribution

CR' = the Conversion Rate in effect immediately after such distribution

SP0 = the Current Market Price of Common Shares on the Record Date for such distribution

84

FMV = the fair market value (as determined by the Board of Directors of the Company) of the Common Shares, evidences of indebtedness, assets or property distributed with respect to each outstanding Common Share on the Record Date for such distribution

Such adjustment shall become effective immediately prior to the opening of business on the day following the Record Date for such distribution.  If the Board of Directors of the Company determines the fair market value of any distribution for purposes of this Section 13.4(c) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price of the Common Shares.

To the extent that the Company has a rights plan in effect upon conversion of the Securities into Common Shares, a Holder shall receive, in addition to the Common Shares, the rights under the rights plan unless the rights have separated from the Common Shares at the time of conversion, in which case the Conversion Rate will be adjusted as if the Company distributed to all holders of Common Shares, Common Shares, evidences of indebtedness or assets, subject to readjustment in the event of the expiration, termination or redemption of such rights.

With respect to an adjustment pursuant to this Section 13.4(c) where there has been a payment of a dividend or other distribution on the Common Shares or common shares of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit (a "Spin-Off"), the Conversion Rate in effect immediately before 5:00 p.m., New York City time, on the effective date fixed for determination of shareholders entitled to receive the distribution shall be increased based on the following formula:

where,

CR0 =          the Conversion Rate in effect immediately prior to such distribution

CR' =           the Conversion Rate in effect immediately after such distribution

FMV0 = the average of the Closing Sale Prices of the Common Shares or similar equity interest distributed to holders of Common Shares applicable to one common share over the ten consecutive Trading-Day period commencing on and including the fifth Trading Day after the date on which Ex-Dividend Trading commences for such distribution on the NYSE Amex Equities or such other national or regional exchange or market on which the Securities are then listed or quoted

MP0 = the average of the Closing Sale Prices of Common Shares over the ten consecutive Trading-Day period commencing on and including the fifth Trading Day after the date on which Ex-Dividend Trading commences for such distribution on the NYSE Amex Equities or such other national or regional exchange or market on which the Securities are then listed or quoted

85

The adjustment to the Conversion Rate under the preceding paragraph will occur on the fourteenth Trading Day after the date on which "Ex-Dividend Trading" commences for such distribution on the NYSE Amex Equities or such other national or regional exchange or market on which the Securities are then listed or quoted.

(d)   If any cash dividend or other distribution is made to all or substantially all holders of Common Shares, the Conversion Rate shall be adjusted based on the following formula:

where,

CR0 =     the Conversion Rate in effect on the Record Date for such distribution

CR' =      the Conversion Rate in effect immediately after the Record Date for such distribution

SP0 = the Current Market Price of one of the Common Shares on the Record Date for such distribution

C =          the amount in cash per share the Company distributes to holders of Common Shares.

Such adjustment shall become effective immediately after 5:00 p.m., New York City time, on the Record Date for such dividend or distribution; provided that if such dividend or distribution is not paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(e)   If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for Common Shares to the extent that the cash and value of any other consideration included in the payment per Common Share exceeds the Current Market Price per Common Share on the Trading Day immediately preceding the date such tender offer or exchange offer is announced, the Conversion Rate shall be increased based on the following formula:

where,

CR0 = the Conversion Rate in effect on the date such tender or exchange offer expires

CR' = the Conversion Rate in effect on the day next succeeding the date such tender or exchange offer expires

86

AC = the fair market value (as determined by the Board of Directors) of the aggregate consideration paid or payable for shares purchased in such tender or exchange offer

OS0 = the number of Common Shares outstanding on the Trading Day immediately preceding the date such tender or exchange offer is announced

OS' = the number of Common Shares outstanding less any shares purchased in the tender or exchange offer at the time such tender or exchange offer expires

SP' = the Current Market Price of Common Shares on the Trading Day immediately preceding the date such tender or exchange offer is announced.

If the Company is obligated to repurchase shares pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange had not been made.

(f)   For purposes of this Section 13.4, the following terms shall have the meaning indicated:

(i)   "Current Market Price" on any date means the average of the Closing Sale Prices per Common Share for the 10 consecutive Trading Days immediately preceding the day before the Record Date (or, if earlier, the Ex-Dividend Date) with respect to any distribution, issuance or other event requiring such computation.

(ii)   "fair market value" shall mean the amount which a willing buyer would pay a willing seller in an arm's length transaction.

(iii)   "Record Date" shall mean, with respect to any dividend, distribution or other transaction or event in which the Holders of Common Shares have the right to receive any cash, securities or other property or in which the Common Shares (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise).

(g)   Subject to subsection (i) below, the Company may make such increases in the Conversion Rate, in addition to any adjustments required by Section 13.4(a), Section 13.4(b), Section 13.4(c), Section 13.4(d), Section 13.4(e) or Section 13.4(f), as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Shares or rights to purchase Common Shares resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes.

7

87

(h)   To the extent permitted by applicable law and subject to subsection (i) below, the Company from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least 20 days, the increase is irrevocable during the period and the Board of Directors shall have made a determination that such increase would be in the best interests of the Company, which determination shall be conclusive.  Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to Holders of record of the Securities a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(i)   Any increase in the Conversion Rate pursuant to subsections (g) and (h) above shall not, without the approval of the shareholders of the Company, as required by Rule 713 of the NYSE Amex Equities Stock Exchange Company Guide, result in the sale or issuance of 20% or more of the Common Shares, or 20% of more of the voting power, outstanding as of the date of this Indenture; unless such shareholder approval is not required pursuant to Section 110 of the NYSE Amex Stock Exchange Company Guide.

(j)   No adjustment in the Conversion Rate shall be required unless such adjustment would require an increase or decrease of at least 1% in such rate; provided, however, that any adjustments which by reason of this Section 13.4(i) are not required to be made shall be carried forward and taken into account in any subsequent adjustment.  All calculations under this Article 13 shall be made by the Company and shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be.  No adjustment need be made for rights to purchase Common Shares pursuant to a Company plan for reinvestment of dividends or interest.  To the extent the Securities become convertible into cash, assets, property or securities (other than Common Shares of the Company), no adjustment need be made thereafter as to the cash, assets, property or such securities. Interest will not accrue on the cash.

(k)   Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any Conversion Agent an Officers' Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment.  Unless and until a Responsible Officer of the Trustee shall have received such Officers' Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect.  Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate to each Holder of Securities at such Holder's last address appearing on the list of Security holders provided for in Section 3.6, within 20 days after execution thereof.  Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

88

(l)   In any case in which this Section 13.4 provides that an adjustment shall become effective immediately after a Record Date for an event, the Company may defer until the occurrence of such event (i) issuing to the Holder of any Securities converted after such Record Date and before the occurrence of such event the additional Common Shares issuable upon such conversion by reason of the adjustment required by such event over and above the Common Shares issuable upon such conversion before giving effect to such adjustment and (ii) paying to such Holder any amount in cash in lieu of any fraction pursuant to Section 13.3.

(m)   For purposes of this Section 13.4, the number of Common Shares at any time outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on Common Shares held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of Common Shares.

(n)   No adjustment to the Conversion Rate shall be made pursuant to this Section 13.4 if the Holders of the Securities may participate in the transaction that would otherwise give rise to an adjustment pursuant to this Section 13.4.

(o)   Whenever any provision of this Indenture requires a calculation of an average of Closing Sale Prices or Daily VWAP over a span of multiple days, the Company shall make appropriate adjustments (determined in good faith by the Board of Directors) to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date of the event occurs at any time during the period from which the average is to be calculated.

Section 13.5     Adjustments Upon Certain Fundamental Changes

(a)   If a Holder elects to convert Securities pursuant to Section 13.1 above in connection with a transaction described therein and the transaction also constitutes a Fundamental Change, the Conversion Rate for such Securities shall be increased by an additional number of Common Shares (the "Additional Shares") as described below. Any conversion occurring at a time when the Securities would be convertible in light of the expected or actual occurrence of a Fundamental Change will be deemed to have occurred in connection with such Fundamental Change notwithstanding the fact that a Security may then be convertible because another condition to conversion has been satisfied.

89

(b)   The number of Additional Shares will be determined by reference to the table attached as Schedule A hereto, based on the date on which the Fundamental Change occurs or becomes effective (the "Effective Date") and the price (the "Share Price") paid per Common Share in the Fundamental Change.  If the Fundamental Change is a transaction described in clause (ii) of the definition of Fundamental Change, and holders of Common Shares receive only cash in that Fundamental Change, the Share Price shall be the cash amount paid per share.  Otherwise, the Share Price shall be the average of the Closing Sale Prices of Common Shares over the five Trading-Day period ending on the Trading Day preceding the Effective Date of the Fundamental Change.

(c)   The Share Prices set forth in the first row of the table in Schedule A hereto shall be adjusted as of any date on which the Conversion Rate of the Securities is otherwise adjusted.  The adjusted Share Prices shall equal the Share Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the share price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares will be adjusted in the same manner as the Conversion Rate as set forth in Section 13.4.

(d)   The table in Schedule A hereto sets forth the hypothetical Share Price and the number of additional shares to be received per $1,000 Principal Amount of Securities.

The exact Share Prices and Effective Dates may not be set forth in the table in Schedule A, in which case:

(i)   If the Share Price is between two Share Price amounts in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares will be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Share Price amounts and the two dates, as applicable, based on a 365-day year.

(ii)   If the Share Price is greater than $34.00 per share (subject to adjustment), no Additional Shares will be issued upon conversion.

(iii)   If the Share Price is less than $8.77 per share (subject to adjustment), no Additional Shares will be issued upon conversion.

Notwithstanding the foregoing, in no event will the total number of Common Shares issuable upon conversion exceed 125.0000 Common Shares per $1,000 Principal Amount of Securities, subject to adjustments in the same manner as the Conversion Rate as set forth in Section 13.4.

90

Section 13.6     Effect Of Reclassification, Consolidation, Merger Or Sale

If any of the following events occur, namely:

(i)   any reclassification or change of Common Shares issuable upon conversion of the Securities (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination, or any other change for which an adjustment is provided in Section 13.4(c));

(ii)   any consolidation, merger or combination to which the Company is a party other than a merger in which the Company is the continuing corporation and which does not result in any reclassification of, or change (other than in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination) in outstanding Common Shares; or

(iii)   any sale or conveyance of all or substantially all of the properties and assets of the Company to any other person as a result of which holders of Common Shares shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Shares,

then the Company or the successor or purchasing person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture) providing that such Securities shall be convertible into the kind and amount of Common Shares, securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance by a holder of a number of Common Shares issuable upon conversion of such Securities (assuming, for such purposes, a sufficient number of authorized Common Shares available to convert all such Securities) immediately prior to such reclassification, change, consolidation, merger, combination, sale or conveyance.  Assuming such holder of Common Shares did not exercise his rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance (provided that, if the kind or amount of stock, securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance is not the same for each share of Common Shares in respect of which such rights of election shall not have been exercised ("non-electing share"), then for the purposes of this Section 13.6, the kind and amount of stock, securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance for each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares).  Such supplemental indenture shall provide that if Holders of Securities would otherwise be entitled to receive, upon conversion of the Securities, any Ineligible Consideration, such Holders shall not be entitled to receive such Ineligible Consideration but the Company or the successor or acquirer, as the case may be, shall have the right (at the sole option of the Company or the successor or acquirer, as the case may be) to deliver either such Ineligible Consideration or Prescribed Securities for the purposes of clause 212(1)(b)(vii)(E) of the Income Tax Act (Canada), as it applied to the 2007 taxation year, with a market value equal to the market value of such Ineligible Consideration.  Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 13.  If, in the case of any such reclassification, change, consolidation, merger, combination, sale or conveyance, the stock, securities or other property or assets (including cash) receivable thereupon by a holder of Common Shares includes shares of stock, securities or other property or assets (including cash) of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, consolidation, merger, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing.

91

The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the register of the Securities maintained by the Registrar, within 20 days after execution thereof.  Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.  The above provisions of this Section shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances.  If this Section 13.6 applies to any event or occurrence, Section 13.4 shall not apply.

Section 13.7     Taxes On Shares Issued

Any issue of stock certificates on conversions of Securities shall be made without charge to the converting Holder for any documentary, transfer, stamp or any similar tax in respect of the issue thereof, and the Company shall pay any and all documentary, stamp or similar issue or transfer taxes that may be payable in respect of the issue or delivery of Common Shares on conversion of Securities pursuant hereto.  The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the Holder of any Securities converted, and the Company shall not be required to issue or deliver any such stock certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

Section 13.8   Reservation Of Shares; Shares To Be Fully Paid; Compliance With Governmental Requirements; Listing Of Common Shares.

The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient Common Shares to provide for the conversion of the Securities from time to time as such Securities are presented for conversion (assuming that, at the time of the computation of such number of shares or securities, all such Securities would be held by a single Holder).

92

Before taking any action that would cause an adjustment increasing the Conversion Rate to an amount that would cause the Conversion Price to be reduced below the then par value, if any, of the Common Shares issuable upon conversion of the Securities, the Company will take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue Common Shares at such adjusted Conversion Price.

The Company covenants that all Common Shares that may be issued upon conversion of Securities shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free from any lien or adverse claim.

The Company shall use its reasonable efforts to list or cause to have quoted any Common Shares to be issued upon conversion of Securities on each national securities exchange or over-the-counter or other domestic market on which the Common Shares are then listed or quoted.

Section 13.9     Responsibility Of Trustee

The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to the Company or any Holder of Securities to determine the Conversion Rate or whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same.  The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any Common Shares, or of any securities or property, which may at any time be issued or delivered upon the conversion of any Securities; and the Trustee and any other Conversion Agent make no representations with respect thereto.  Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any Common Shares or stock certificates or other securities or property or cash upon the surrender of any Securities for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 13.  Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 13.6 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Securities after any event referred to in such Section 13.6 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 6.1, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers' Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto.

93

Section 13.10    Notice To Holders Prior To Certain Actions

In case,

(a)   the Company shall declare a dividend (or any other distribution) on its Common Shares that would require an adjustment in the Conversion Rate pursuant to Section 13.4; or

(b)   the Company shall authorize the granting to the holders of all or substantially all of its Common Shares of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants; or

(c)   of any reclassification or reorganization of the Common Shares of the Company (other than a subdivision or combination of its outstanding Common Shares, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company or any of its significant subsidiaries; or

(d)   of the voluntary or involuntary dissolution, liquidation or winding up of the Company or any of its significant subsidiaries;

then, in each case, the Company shall cause to be filed with the Trustee and the Conversion Agent and to be mailed to each Holder of Securities at such Holder's address appearing on the list of Security holders provided for in Section 3.6 of this Indenture, as promptly as practicable but in any event at least 15 days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Shares of record to be entitled to such dividend, distribution or rights are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up is expected to become effective or occur, and the date as of which it is expected that holders of Common Shares of record shall be entitled to exchange their Common Shares for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

Section 13.11    Company Determination Final

Any determination that the Company or its Board of Directors must make pursuant to this Article 13 shall be conclusive if made in good faith and in accordance with the provisions of this Article 13, absent manifest error, and set forth in a Board Resolution.
