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 104.Acts of Holders. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders of the Outstanding Notes may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments or so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Note, shall be sufficient for any purpose of this Indenture and 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 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 deems sufficient.

(c)The principal amount and serial numbers of Notes held by any Person, and the date of holding the same, shall be proved by the Register.

(d)If the Company shall solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. Such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date

12

shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of Outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Notes shall be computed as of such record date; provided, however, that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than eleven months after the record date, and that no such authorization, agreement or consent may be amended, withdrawn or revoked once given by a Holder, unless the Company shall provide for such amendment, withdrawal or revocation in conjunction with such solicitation of authorizations, agreements or consents or unless and to the extent required by applicable law. If the Company elects not to fix in advance a record date, then the record date shall be 30 days prior to the first solicitation of any such consent.

(d)Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note 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 Note.

SECTION 105.Notices, Etc. to Trustee and Company. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other documents provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,

(1)the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if in writing and mailed (first class postage prepaid) or sent by facsimile to the Trustee at its Corporate Trust Office, Attention: NOVA Chemicals Administrator, or

(2)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) or sent by facsimile to the Company addressed to: c/o NOVA Chemicals Inc., 1000 7^th Avenue, S.W., Calgary, Alberta, T2P SL5, Attention: Vice President & Deputy General Counsel, or at any other address previously furnished in writing to the Trustee by the Company.

SECTION 106.Notice to Holders; Waiver. Where this Indenture provides for notice of any event to Holders by the Company or the Trustee, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, or, in the case of Notes issued in global form, delivered electronically, to each such Holder affected by such event, at his address as it appears in the Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders is given by mail or delivered electronically, neither the failure to mail or deliver electronically, as applicable, such notice, nor any defect in any notice so mailed or delivered electronically, as applicable, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Any notice mailed or delivered electronically, as applicable, to a Holder in the manner herein prescribed shall be conclusively

13

deemed to have been received by such Holder, whether or not such Holder actually receives such notice.

In case, by reason of the suspension of or irregularities in regular mail service or by reason of any other cause, it shall be impractical to mail or deliver electronically, as applicable, notice of any event to Holders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Trustee shall be deemed to be sufficient giving of such notice for every purpose hereunder.

Any request, demand, authorization, direction, notice, consent or waiver required or permitted under this Indenture shall be in the English language, except that any published notice may be in an official language of the country of publication.

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.

SECTION 107.Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

SECTION 108.Successors and Assigns. All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not.

SECTION 109.Separability Clause. In case any provision in this Indenture or in any Note shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 110.Benefits of Indenture. Nothing in this Indenture or in the Notes, express or implied, shall give to any Person, other than the parties hereto, any Agent and their successors hereunder and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture.

SECTION 111.Governing Law. This Indenture and the Notes shall be governed by and construed in accordance with the laws of the State of New York, without giving effect to applicable principles of conflicts of law to the extent that the application of the laws of another jurisdiction would be required thereby.

SECTION 112.Legal Holidays. In any case where any Interest Payment Date, Redemption Date, or Stated Maturity or Maturity of any Note shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Notes) payment of interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity or Maturity; provided, however, that no interest shall accrue for

14

the period from and after such Interest Payment Date, Redemption Date, Stated Maturity or Maturity, as the case may be.

SECTION 113.Conversion of Currency. The Company covenants and agrees that the following provisions shall apply to conversion of currency in the case of the Notes and this Indenture:

(i)(A) If for the purpose 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 in the payment currency (the “payment currency”), then the conversion shall be made at the rate of exchange prevailing on the Business Day before the day on which the judgment is given or the order of enforcement is made, as the case may be (unless a court shall otherwise determine).

(B) If there is a change in the rate of exchange prevailing between the Business Day before the day on which the judgment 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 will 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 payment currency originally due.

(ii)In the event of the winding-up of the Company at any time while any amount or damages owing under the Notes and this Indenture, or any judgment or order rendered in respect thereof, shall remain outstanding, the Company shall indemnify and hold the Holders 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 payment currency due or contingently due under the Notes and this Indenture (other than under this Subsection (ii)) 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 Subsection (ii), 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.

(iii)The obligations contained in Subsections (i)(B) and (ii) of this Section 113 shall constitute separate and independent obligations of the Company from its other obligations under the Notes 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 the Trustee or any of them 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 Subsection (ii) above) or under any such judgment or order and the discharge of this Indenture. Any such deficiency as aforesaid shall be

15

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 liquidator or otherwise or any of them. In the case of Subsection (ii) 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.

(iv)The term “rate(s) of exchange” shall mean the noon rate of exchange quoted by the Bank of Canada for purchases of the payment currency with the judgment currency other than the payment currency referred to in Subsections (i) and (ii) above and includes any premiums and costs of exchange payable.

SECTION 114.Appointment of Agent for Service. By the execution and delivery of this Indenture, the Company (i) acknowledges that it has, by separate written instrument, irrevocably designated and appointed CT Corporation System, 111 Eighth Avenue, New York, New York 10011, as its authorized agent upon which process may be served in any suit or proceeding arising out of or relating to the Notes or this Indenture that may be instituted in any Federal or State court in the State of New York, Borough of Manhattan, or brought under Federal or State securities laws or brought by the Trustee (whether in its individual capacity or in its capacity as Trustee hereunder), and acknowledges that CT Corporation System has accepted such designation, (ii) submits to the jurisdiction of any such court in any such suit or proceeding, and (iii) agrees that service of process upon CT Corporation System and written notice of said service to the Company (mailed or delivered to its Vice President and Deputy General Counsel at the address specified in Section 105(2)) shall be deemed in every respect effective service of process upon it in any such suit or proceeding. The Company further agrees to take any and all action, including the execution and filing of any and all such documents and instruments, as may be necessary to continue such designation and appointment of CT Corporation System in full force and effect so long as this Indenture shall be in full force and effect and so long as any of the Notes shall be outstanding.

To the extent that the Company has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service of notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, the Company hereby irrevocably waives such immunity in respect of its obligations under this Indenture and the Notes, to the extent permitted by law.

The Company hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Indenture or the Notes in any Federal or State court in the State of New York, Borough of Manhattan. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the

18

Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Note.

(b)Transfers of Global Notes shall be limited to transfer in whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in the Global Notes may be transferred or exchanged for Physical Notes in accordance with the rules and procedures of the Depositary and the provisions of Section 205. In addition, a Global Note shall be exchangeable for Physical Notes if (i) the Depositary (x) notifies the Company that it is unwilling or unable to continue as depository for such Global Note and the Company thereupon fails to appoint a successor depository or (y) has ceased to be a clearing agency registered under the Exchange Act, (ii) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of such Physical Notes or (iii) there shall have occurred and be continuing an Event of Default with respect to the Notes. In all cases, Physical Notes delivered in exchange for any Global Note or beneficial interests therein shall be registered in the names, and issued in any approved denominations, requested by or on behalf of the Depositary (in accordance with its customary procedures).

(c)In connection with any transfer or exchange of a portion of the beneficial interest in any Global Note to beneficial owners of Physical Notes pursuant to paragraph (b), the Registrar shall reflect on its books and records the date and a decrease in the principal amount of the Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be transferred or exchanged, and the Company shall execute, and the Trustee shall upon receipt of a written order from the Company authenticate and make available for delivery, one or more Physical Notes of like tenor and amount.

19

that the transferor reasonably believes is a Qualified Institutional Buyer in a transaction meeting the requirements of Rule 144A or (b) pursuant to another exemption from the registration requirements under the Securities Act which is accompanied by an Opinion of Counsel regarding the availability of such exemption and (ii) in accordance with all applicable securities laws of any state of the United States or any other jurisdiction.

(g)Beneficial interests in the Global Note may be transferred to a Person who takes delivery in the form of an interest in the Regulation S Note, whether before or after the expiration of the Restricted Period, only if the transferor first delivers to the Trustee a written certificate to the effect that such transfer is being made in accordance with Regulation S or Rule 144 (if available) and that, if such transfer occurs prior to the expiration of the Restricted Period, the interest transferred will be held immediately thereafter through Euroclear or Clearstream.

(h)Any beneficial interest in one of the Global Notes that is transferred to a Person who takes delivery in the form of an interest in another Global Note shall, upon transfer, cease to be an interest in such Global Note and become an interest in such other Global Note and, accordingly, shall thereafter be subject to all transfer restrictions and other procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest.

(i)The Holder of any Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes.

SECTION 205.Special Transfer Provisions. (%5) Transfers to QIBs. The following provisions shall apply with respect to the registration or any proposed registration of transfer of any Note constituting a Restricted Security to a QIB (excluding transfers to Non-U.S. Persons):

(ii)if the proposed transferee is an Agent Member, and the Notes to be transferred consist of Physical Notes which after transfer are to be evidenced by an interest in the Global Note, upon receipt by the Registrar of instructions given in accordance with the Depositary’s and the Registrar’s procedures, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Note in an amount equal to the principal amount of the Physical Notes to be transferred, and the Trustee shall cancel the Physical Notes so transferred.

Upon the registration of transfer, exchange or replacement of Notes not bearing the Private Placement Legend, the Registrar shall deliver Notes that do not bear the Private Placement Legend. Upon the registration of transfer, exchange or replacement of Notes bearing the Private Placement Legend, the Registrar shall deliver only Notes that bear the Private Placement Legend unless (i) there is delivered to the Registrar an Opinion of Counsel reasonably satisfactory to the Company and the Trustee to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act or (ii) such Note has been sold pursuant to an effective registration statement under the Securities Act and the Registrar has received an Officers’ Certificate from the Company to such effect.

SECTION 206.CUSIP Number. The Company in issuing the Notes may use a “CUSIP” number, and if so, such CUSIP number shall be included in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed in the notice or on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the Trustee in writing of any such CUSIP number used by the Company in connection with the issuance of the Notes and of any change in the CUSIP number.

In authenticating such Notes, and accepting the additional responsibilities under this Indenture in relation to such Notes, the Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel stating:

(a)that the form or forms of such Notes have been established in conformity with the provisions of this Indenture; and

(b)that such Notes when completed by appropriate insertions and executed and delivered by the Company to the Trustee for authentication in accordance with this Indenture, and authenticated and delivered by the Trustee in accordance with this Indenture and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute the valid and binding obligations of the Company, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization, fraudulent conveyance and other similar laws of general applicability relating to or affecting the enforcement of creditors’ rights, and to general equitable principles.

The Trustee shall not be required to authenticate and deliver any such Notes if the issue of such Notes pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Notes and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

Each Note shall be dated the date of its authentication.

No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication substantially in the form provided for herein, duly executed by the Trustee by manual signature of an authorized officer, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Note shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the

22

Company shall deliver such Note to the Trustee for cancellation as provided in Section 310 together with a written statement (which need not comply with Section 102 and need not be accompanied by an Opinion of Counsel) stating that such Note has never been issued and sold by the Company, for all purposes of this Indenture such Note shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

SECTION 304.Temporary Notes. Pending the preparation of definitive Notes, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Notes which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Notes may determine, as evidenced by their execution of such Notes. Such temporary Notes may be Global Notes.

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

SECTION 305.Registration, Registration of Transfer and Exchange. Upon surrender for registration of transfer of any Note at the office or agency of the Trustee in a Place of Payment, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee, one or more new Notes, of any authorized denominations and of a like aggregate principal amount and tenor.

At the option of the Holder, Notes may be exchanged for other Notes, of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes which the Holder making the exchange is entitled to receive.

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

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

No service charge shall be made for any registration of transfer or exchange of Notes, but the Company may require payment of a sum sufficient to cover any tax or other

23

governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, other than exchanges pursuant to Section 304, 906, 1107 or 1305 not involving any transfer.

The Company shall not be required (i) to issue, register the transfer of or exchange Notes during a period beginning at the opening of business 15 Business Days before the day of the selection for redemption of Notes under Section 1103 or 1203 and ending at the close of business on the day of the mailing or electronic delivery, as applicable, of the relevant notice of redemption or (ii) to register the transfer of or exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part, or (iii) to issue, register the transfer of or exchange any Note which has been surrendered for repayment at the option of the Holder, except the portion, if any, of such Note not to be so repaid.

SECTION 306.Mutilated, Destroyed, Lost and Stolen Notes. If any mutilated Note is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding or, in case any such mutilated Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note.

If there shall be delivered to the Company and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Note 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 Note has been acquired by a bona fide purchaser, the Company shall execute and upon receipt of a Company Order the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding, or, in case any such destroyed, lost or stolen Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note pay such Note.

Upon the issuance of any new Note under this Section 306, 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 Note issued pursuant to this Section 306 in lieu of any destroyed, lost or stolen Note shall constitute a valid contractual obligation of the Company evidencing the same debt as the Note in lieu of which it is issued, whether or not the destroyed, lost or stolen Note 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 Notes.

The provisions of this Section 306 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 Notes.

SECTION 307.Payment of Interest; Interest Rights Preserved. (a) Interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose pursuant to Section 1002; provided, however, that each installment of interest on any Note may at the Company’s option be paid by (i) mailing a check for such interest, payable to or upon the written order of the Person entitled thereto pursuant to Section 309, to the address of such Person as it appears on the Register or (ii) transferring such interest to an account maintained by the payee located inside the United States.

(b)[RESERVED]

(c)Subject to the foregoing provisions of this Section and Section 305, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

SECTION 309.Persons Deemed Owners. Prior to due presentment of a Note 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 Note is registered as the legal owner of such Note for the purpose of receiving payment of principal of (and premium, if any) and (subject to Sections 305 and 307) interest on such Note and for all other purposes whatsoever, whether or not such Note 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.

None of the Company, the Trustee, any Paying Agent, or any Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Notwithstanding the foregoing, with respect to any Global Note, nothing herein shall prevent the Company, the Trustee, or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by any depositary, as a Holder, with respect to such Global Note or impair, as between such depositary and owners of beneficial interests in such Global Note, the operation of customary practices governing the exercise of the rights of such depositary (or its nominee) as Holder of such Global Note.

SECTION 310.Cancellation. All Notes surrendered for payment, redemption, repayment at the option of the Holder, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Notes so delivered to the Trustee shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Notes previously

25

authenticated hereunder which the Company has not issued and sold, and all Notes so delivered, shall be promptly cancelled by the Trustee. If the Company shall so acquire any of the Notes, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in this Section, except as expressly permitted by this Indenture. Unless by Company Order the Company directs the return of any cancelled Notes to it, all cancelled Notes shall be destroyed by the Trustee and upon written request of the Company the Trustee shall deliver its certificate of such destruction to the Company.

SECTION 311.Computation of Interest. Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months.

SECTION 312.Currency of Notes. Payment of the principal of (and premium, if any) and interest, if any, on the Notes will be made in Dollars.

SECTION 313.[RESERVED]

SECTION 314.Registrar and Paying Agent. The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (the “Registrar”), and an office or agency where Notes may be presented for payment (the “Paying Agent”) and an office or agency where notices and demands to or upon the Company, if any, in respect of the Notes and this Indenture may be served. The Registrar shall keep a register of the Notes and of their transfer and exchange (the “Register”). The Company may have one or more additional Paying Agents. The term “Paying Agent” includes any additional Paying Agent. Neither the Company nor any Affiliate thereof may act as a Paying Agent.

The Company shall enter into an appropriate agency agreement with any Agent that is not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee of the name and address of any such Agent. If the Company fails to maintain a Registrar or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as such and shall be entitled to appropriate compensation in accordance with Section 607.

The Company initially appoints the Trustee as Registrar or Paying Agent and Agent for service of notices and demands in connection with the Notes and this Indenture.

SECTION 315.Paying Agent To Hold Money in Trust. Each Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal of or premium or interest on the Notes (whether such money has been paid to it by the Company or any other obligor on the Notes), and the Company and the Paying Agent shall notify the Trustee of any default by the Company (or any other obligor on the Notes) in making any such payment. Money held in trust by the Paying Agent need not be segregated except as required by law. The Company at any time may require the Paying Agent to pay all money held by it to the Trustee and account for any funds disbursed and the Trustee may at any time during the continuance of any Event of Default specified in Section 501(1) or (2), upon written request to the Paying Agent, require such Paying Agent to pay

26

forthwith all money so held by it to the Trustee and to account for any funds disbursed. Upon making such payment, the Paying Agent shall have no further liability for the money delivered to the Trustee. The Paying Agent shall invest money held by it only upon the written instructions of the Company. Upon any Event of Default specified in Section 501(5) or (6), the Trustee shall be the Paying Agent.

SECTION 316.Noteholder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of the Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least five Business Days before each Interest Payment Date, and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders.

SECTION 317.Transfer and Exchange. Subject to Sections 204 and 205, when Notes are presented to the Registrar with a request from the Holder of such Notes to register a transfer or to exchange them for an equal principal amount of Notes of other authorized denominations, the Registrar shall register the transfer as requested. Every Note presented or surrendered for registration of transfer or exchange shall be duly endorsed or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar, duly executed by the Holder thereof or his attorneys duly authorized in writing. To permit registrations of transfers and exchanges, the Company shall issue and execute and the Trustee shall authenticate new Notes evidencing such transfer or exchange at the Registrar’s request. No service charge shall be made to the Holder for any registration of transfer or exchange. The Company may require from the Holder payment of a sum sufficient to cover any transfer taxes or other governmental charge that may be imposed in relation to a transfer or exchange, but this provision shall not apply to any exchange pursuant to Section 304 or 1107, (in which events the Company shall be responsible for the payment of such taxes). The Registrar shall not be required to exchange or register a transfer of any Note for a period of 15 days immediately preceding the mailing or electronic delivery, as applicable, of notice of redemption of Notes to be redeemed or of any Note selected, called or being called for redemption except the unredeemed portion of any Note being redeemed in part.

Any Holder of the Global Note or a beneficial interest in the Global Note shall, by acceptance of such Global Note or beneficial interest, agree that transfers of the beneficial interests in such Global Note may be effected only through a book entry system maintained by the Holder of such Global Note (or its agent), and that ownership of a beneficial interest in the Global Note shall be required to be reflected in a book entry.

Except as expressly provided herein, neither the Trustee nor the Registrar shall have any duty to monitor the Company’s compliance with or have any responsibility with respect to the Company’s compliance with any Federal or state securities laws.

SECTION 318.Outstanding Notes. The Notes outstanding at any time are all Notes that have been authenticated by the Trustee except for (a) those canceled by it, (b) those delivered to it for cancellation, (c) to the extent set forth in Sections 1401, on or after the date on which the conditions set forth in Section 1401 have been satisfied, those Notes theretofore

27

authenticated and delivered by the Trustee hereunder and (d) those described in this Section 318 as not outstanding.

If a Note is replaced pursuant to Section 306, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser in whose hands such Note is a legal, valid and binding obligation of the Company.

If the Paying Agent holds, in its capacity as such, on the Maturity Date, money sufficient to pay all accrued interest and principal with respect to the Notes payable on that date and is not prohibited from paying such money to the Holders thereof pursuant to the terms of this Indenture, then on and after that date such Notes cease to be outstanding and interest on them ceases to accrue.

SECTION 502.Acceleration of Maturity; Rescission and Annulment. If an Event of Default described in clauses (1), (2), (3), (4), (5) (unless with respect to the Company), (6) (unless with respect to the Company) or (7) of Section 501 with respect to Notes at the time Outstanding shall occur and be continuing, then in every such case the Trustee by written notice to the Company or the Holders of not less than 25% in aggregate principal amount of the Outstanding Notes by written notice to the Company with a copy to the Trustee may declare the

30

principal amount and all other amounts owing thereunder of all of the Notes to be due and payable immediately by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified portion thereof) and all other amounts owing thereunder shall become immediately due and payable. If any Event of Default described in clause (5) (with respect to the Company) or (6) (with respect to the Company) of Section 501 occurs and is continuing, all principal amount and all other amounts owing under outstanding Notes will become immediately due and payable without any declaration or other act or notice on the part of the Trustee or the Holders.

At any time after such a declaration of acceleration with respect to the Notes 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 Five provided, the Holders of a majority in principal amount of the Outstanding Notes, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if

(2)all Events of Default with respect to Notes, other than the non-payment of amounts of principal of (or premium, if any) or interest on Notes which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513.

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

SECTION 503.Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if

(1)default is made in the payment of any installment of interest on any Note when such interest becomes due and payable and such default continues for a period of 30 days, or

31

(2)default is made in the payment of the principal of (or premium, if any, on) any Note at the Maturity thereof,

then the Company will, upon demand of the Trustee, pay to the Trustee for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes for principal (and premium, if any) and interest, and interest on any overdue principal (and premium, if any), and to the extent that payment of such interest is lawful, interest on any overdue interest, at the rate or rates prescribed therefor in such Notes, 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 as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Notes, wherever situated.

If an Event of Default with respect to Notes occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Notes by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 504.Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Notes or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal, premium, if any, or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(i)to file and prove a claim for the whole amount of principal (and premium, if any), and interest owing and unpaid in respect of the Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and

(ii)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 of such payments directly

32

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 607.

Nothing herein contained 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 Notes 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.

All rights of action and claims under this Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes in respect of which such judgment has been recovered.

SECTION 506.Application of Money Collected. Any money or property collected by the Trustee pursuant to this Article 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 or property on account of principal (or premium, if any, on) or interest, upon presentation of the Notes, 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 under Section 607;

Second: To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest on the Notes, ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes for principal (and premium, if any) and interest, respectively; and

Third: The balance, if any, to the Company or any other Person or Persons entitled thereto.

SECTION 507.Limitation on Suits. No Holder of any Note 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, unless

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

(2)the Holders of not less than 25% in aggregate principal amount of the Outstanding Notes in the case of any Event of Default described in Section 501 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;

33

(3)such Holder or Holders have offered to the Trustee indemnity or security satisfactory to the Trustee against any loss, liability or expense which might be incurred by the Trustee in connection with such request or direction;

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

(5)no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of not less than a majority in principal amount of the Outstanding Notes in the case of any Event of Default described in Section 501;

it being understood and intended that no one or more of such 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 of Notes, in the case of any Event of Default described in Section 501, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all Holders of Notes, in the case of any Event of Default described in Section 501.

SECTION 508.Unconditional Right of Holders to Receive Principal, Premium and Interest.

SECTION 509.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 514.Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Note by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, 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, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply

In case any Notes 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 Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes; and in case at that time any of the Notes shall not have been authenticated, any successor Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

SECTION 612.Appointment of Authenticating Agent. At any time when any of the Notes remain Outstanding, the Trustee may appoint an Authenticating Agent which shall be authorized to act on behalf of the Trustee to authenticate Notes and the Trustee shall give written notice of such appointment to all Holders of Notes, in the manner provided for in Section 106. Notes so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Any such appointment shall be evidenced by an instrument in writing signed by a Responsible Officer of the Trustee, and a copy of such instrument shall be promptly furnished to the Company.

If such corporation or national banking association publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation or national banking association shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect specified in this Section.

Any corporation or national banking association into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation or national banking association succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation or national banking association shall be otherwise eligible

42

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company.

Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give written notice of such appointment to all Holders of Notes, in the manner provided for in Section 106. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 607.

The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in accordance with the requirements set forth above for Notes for such purposes.

The Company hereby designates as a Place of Payment as the Borough of Manhattan, The City of New York, and initially appoints the Trustee at its New York office as Paying Agent in such Place of Payment and as its agent to receive all presentations, surrenders, notices and demands.

SECTION 1007.Limitation on Sale/Leaseback Transactions. The Company will not, and will not permit any Subsidiary to, enter into any Sale/Leaseback Transaction with respect to any property or assets, whether owned on the date of this Indenture or hereafter acquired, unless (i) the Company or such Subsidiary would be entitled to create Security Interests on such property securing such Attributable Debt without equally and ratably securing the Notes pursuant to the covenant described under Section 1006 or (ii) the net cash proceeds received by the Company or any Subsidiary in connection with such Sale/Leaseback Transaction are at least equal to the fair value (as determined by the Board of Directors of the Company or, as the case may be, such Subsidiary) of such property or assets, and the Company or such Subsidiary shall apply or cause to be applied, in the case of a sale or transfer for cash, an amount equal to the net proceeds thereof and, in the case of a sale or transfer otherwise than for cash, an amount equal to the fair market value of the property so leased, to the retirement, within 180 days after the effective date of such Sale/Leaseback Transaction, of the Notes subject to the provisions of Article Eleven or Debt of the Company ranking pari passu in right of payment with the Notes and owing to a Person other than the Company or any Affiliate of the Company or to the construction or improvement of real property or personal property used in the ordinary course of business.

by or on behalf of the Government of Canada or any other jurisdiction in which such payments are made on behalf of the Company or in which the Company is resident for tax purposes, including, in each case, any province or territory thereof or by any authority or agency therein or thereof (the “Relevant Tax Jurisdiction”) having power to tax (“Taxes”), unless the Company is required to withhold or deduct Taxes under the law of the Relevant Tax Jurisdiction or by the interpretation or administration thereof. If, after the date of this Indenture, the Company is so required to withhold or deduct any amount for or on account of Taxes (other than United States “backup” withholding) from any payment made under or in respect to the Notes, the Company will pay to each holder of Notes such additional amounts (“Tax Gross-Up Amounts”) as may be necessary so that the net amount received by such holder (including the Tax Gross-Up Amounts) after such withholding or deduction (including any deduction or withholding in respect of the Tax Gross-Up Amounts) will not be less than the amount such holder would have received if such Taxes had not been withheld or deducted; provided that no Tax Gross-Up Amounts will be payable with respect to a payment made to a holder or Beneficial Owner of Notes (to the extent that any of the following apply, such holder or Beneficial Owner shall be referred to as an “Excluded Holder”):

(d)which fails to comply with any certification, identification, information, documentation or other reporting requirement if compliance is required by applicable law, regulation or administrative practice as a condition to exemption from or a reduction in the rate of deduction or withholding of Taxes, but only to the extent the holder is legally entitled to comply with such requirements and only if such holder received a written request from the Company delivered reasonably in advance of the date the compliance is required ; or

(e)which is a fiduciary or partnership or person other than the sole Beneficial Owner of such payment to the extent that the Taxes would not have been imposed on such payment had such holder been the sole Beneficial Owner of such Notes.

The Company will also:

(a)make such withholding or deduction, and

(b)remit the full amount deducted or withheld to the Relevant Tax Jurisdiction in accordance with applicable law.

57

If the Company is required to withhold or deduct any such amounts on account of Taxes, the Company will furnish to holders of Notes outstanding on the date of such payment of Taxes copies of the Information Return NR4 and any other information returns applicable in Canada within 30 days of the date that each such return is required to be filed with the Canadian taxing authorities.

(b)any liability (including penalties, interest and expense) of such holder arising therefrom or with respect thereto, and

(c)any Taxes levied or imposed on such holder with respect to any reimbursement under clause (a) or (b) above.

Whenever in this Indenture or any Note there is mentioned, in any context:

(a)the payment of principal (and premium, if any),

(b)purchase prices in connection with a repurchase of Notes,

(c)interest, or

(d)any other amount payable on or with respect to any of the Notes,

(%5) Upon the occurrence of a Change of Control, the Company will make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to U.S.$2,000 or an integral multiple of U.S.$1,000 in excess thereof) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest on the Notes repurchased to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company will mail or, in the case of Notes issued in global form, deliver electronically, a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating:

58

(1)that the Change of Control Offer is being made pursuant to this Section 1010 and that all Notes tendered will be accepted for payment;

(2)the purchase price and the purchase date, which shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed or delivered electronically, as applicable (the “Change of Control Payment Date”);

(3)that any Note not tendered will continue to accrue interest;

(4)that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date;

(5)that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

(6)that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and

(7)that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to U.S.$2,000 in principal amount or an integral multiple of U.S.$1,000 in excess thereof.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with this Section 1010 hereof, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 1010 by virtue of such compliance.

(b)On the Change of Control Payment Date, the Company will, to the extent lawful:

The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(c)Notwithstanding anything to the contrary in this Section 1010, the Company will not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 1010 and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to Article 11 hereof, unless and until there is a default in payment of the applicable redemption price.

(d)Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.

(e)If Holders of not less than 90% in aggregate principal amount of the outstanding Notes properly tender and do not withdraw such Notes in a Change of Control Offer (or an offer made by a third party as described above) and the Company, or any third party making an offer in lieu of the Company, as described above, purchase all of the Notes properly tendered and not withdrawn by such Holders, the Company or the third party making such offer will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer or offer by such third party described above, to redeem all the Notes that remain outstanding following such purchase at a redemption price in cash equal to the applicable Change of Control Payment.

SECTION 1106.Notes Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Notes so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified in Dollars (together with accrued interest, if any, to the Redemption Date), and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Notes shall, if the same were interest bearing, cease to bear interest. Upon surrender of any such Note for redemption in accordance with said notice, such Note shall be paid by the Company at the Redemption Price, together with accrued interest, if any, to the Redemption Date; provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable (but without interest thereon, unless the Company shall default in the payment thereof) to the Holders of such Notes, or one or more Predecessor Notes, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307.

Such limitations are subject to a number of important qualifications and exceptions. Pursuant to Section 1004 of the Indenture, the Company must annually report to the Trustee on compliance with such limitations.

14.    Successor Corporation. When a successor corporation assumes all the obligations of its predecessor under the Notes and the Indenture and the transaction complies with the terms of Article Eight of the Indenture, the predecessor corporation will, except as provided in Article Eight, be released from those obligations.

Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require indemnity or security satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power.

16.    Trustee Dealings with Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee.

No director, officer, employee, incorporator, member of the Board of Directors or holder of Capital Stock of the Company, as such, will have any liability for any obligations of the Company under this Note or the Indenture or for any claim based on, in respect of, or by reason of, such obligations. Each Holder of this Note by accepting this Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of this Note.

18.    Discharge. The Company’s obligations pursuant to the Indenture will be discharged, except for obligations pursuant to certain sections thereof, subject to the terms of the Indenture, upon the payment of all the Notes or upon the irrevocable deposit with the Trustee of United States dollars or U.S. Government Obligations sufficient to pay when due principal of and interest on the Notes to maturity or redemption, as the case may be.
