The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency designated pursuant to Section 1002 being herein sometimes referred to as the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. The Security Register shall be in written form or any other form capable of being converted into written form within a reasonable time. The Trustee is hereby initially appointed as security registrar (the "Security Registrar") for the purpose of registering Notes and transfers of Notes as herein provided.

Upon surrender for registration of transfer of any Note at the office or agency of the Company designated pursuant to Section 1002, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denomination or denominations of a like aggregate principal amount.

At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination 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.

Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 301, any permanent global Note shall be exchangeable only as provided in this paragraph. If any beneficial owner of an interest in a permanent global Note is entitled to and requests exchange of such interest for Notes in definitive form, provided that any applicable notice provided in the permanent global Note shall have been given, then without unnecessary delay but in any event not later than the earliest date on which such interest may be so exchanged, the Company shall deliver to the Trustee definitive Notes in aggregate principal amount equal to the principal amount of such beneficial owner's interest in such permanent global Note, executed by the Company. On or after the earliest date on which such interests may be so exchanged, such permanent global Note shall be surrendered by the Depository or such other depository as shall be specified in the Company Order with respect thereto to the Trustee, as the Company's agent for such purpose, to be exchanged, in whole or from time to time in part, for definitive Notes without charge, and the Trustee shall authenticate and deliver, in exchange for each portion of such permanent global Note, an equal aggregate principal amount of definitive Notes of the same series of authorized denomination and of like tenor as the portion of such permanent global Note to be exchanged which shall be in the form of Registered Notes; provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Notes to be redeemed and ending on the relevant Redemption Date if the Note for which exchange is requested may be among those selected for redemption. If a Registered Note is issued in exchange for any portion of a permanent global Note after the close of business at the office or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such registered Note, but will be payable on such Interest Payment Date or proposed date for payment, as

the case may be, only to the Person to whom interest in respect of such portion of such permanent global Note is payable in accordance with the provisions of this Indenture.

All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Company, and, pursuant to the Guarantee, the Guarantor, shall evidence the same debt, and be 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 Security Registrar) 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.

No service charge shall be made for any registration of transfer or exchange or redemption of Notes, 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 Notes, other than exchanges pursuant to this Section 304, 906 or 1108 not involving any transfer.

The Company shall not be required (i) to issue, register the transfer of or exchange any Note during a period beginning at the opening of business 15 days before the selection of Notes to be redeemed under Section 1104 and ending at the close of business on the day of such mailing 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.

SECTION 305 Mutilated, Destroyed, Lost and Stolen Notes.

If (i) any mutilated Note is surrendered to the Trustee, or (ii) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, and there is delivered to the Company and the Trustee such security or indemnity as may be required by them to save each 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 Company Order the Trustee shall authenticate and deliver, in exchange for any such mutilated Note or in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount, bearing a number not contemporaneously outstanding.

In case any such mutilated, 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, 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 in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Company, and, pursuant to the Guarantee, the Guarantor, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Notes 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 Notes.

SECTION 306 Payment of Interest; Interest Rights Preserved.

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 instalment of interest may, at the option of the Company, be paid by mailing a check for such interest payable to, or upon the written order of, the Person entitled thereto pursuant to Section 307 to the address of such Person as it appears in the Security Register.

Any interest on any Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to the Holder on the Regular Record Date by virtue of having been such Holder, and such defaulted interest and (to the extent lawful) interest on such defaulted interest at the rate borne by the Notes plus one per cent (such defaulted interest and interest thereon herein collectively called "Defaulted Interest") may be paid by the Company, at its election in each case, as provided in Clause (1) or (2) below:

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective Predecessor Notes) 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 Note and the date of the proposed payment, 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 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 date of the proposed payment 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 therefor to be given in the manner provided for in Section 106, 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 therefor having been so given, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2).

(2) 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 Notes 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, 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 307 Persons Deemed Owners.

Prior to the due presentment of a Note for registration of transfer, the Company, the Guarantor, the Trustee and any agent of the Company, the Guarantor or the Trustee may treat the Person in whose

name such Note is registered as the owner of such Note for the purpose of receiving payment of principal of, premium, if any, and (subject to Sections 304 and 306) interest on such Note and for all other purposes whatsoever, whether or not such Note be overdue, and none of the Company, the Guarantor, the Trustee or any agent of the Company, the Guarantor or the Trustee shall be affected by notice to the contrary.

None of the Company, the Trustee, any Paying Agent or the Security 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 Note in global form 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 308 Cancellation.

All Notes surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and 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 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. All cancelled Notes held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures and certification of their disposal delivered to the Company unless by Company Order the Company shall direct that cancelled Notes be returned to it.

SECTION 309 Computation of Interest.

Interest on the Notes shall be computed on the basis of a 360-day year consisting of twelve 30-day months. For the purposes of the Interest Act (Canada), the yearly rate of interest which is equivalent to the rate payable hereunder is the rate payable multiplied by the actual number of days in the year and divided by 360.

SECTION 401 Satisfaction and Discharge of Indenture.

This Indenture shall upon Company Request cease to be of further effect (except as to surviving rights of registration of transfer or exchange of Notes expressly provided for herein or pursuant hereto) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture when

(4) if the Guarantee shall, for any reason cease to be, or be asserted in writing by the Guarantor or any Subsidiary of the Guarantor, not to be, in full force and effect, enforceable in accordance with its terms, except pursuant to the release of such Guarantee in accordance with this Indenture; or

(5) one or more defaults by the Company or any Subsidiary of the Company under one or more evidences of Debt or instruments governing the same with a principal amount then outstanding, individually or in the aggregate, in excess of U.S.$25,000,000, which default or defaults shall constitute a failure to pay any portion of the principal of such Debt when due and payable after the expiration of any applicable grace period with respect thereto or shall have resulted in such Debt becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable; or

(6) a final judgment or final judgments for the payment of money are entered against the Company or any Subsidiary of the Company in an aggregate amount in excess of U.S.$25,000,000 by a court or courts of competent jurisdiction, which judgments remain undischarged or unbounded for a period (during which execution shall not be effectively stayed) of 60 days after the right to appeal all such judgments has expired; or

SECTION 502 Acceleration of Maturity: Rescission and Annulment.

If an Event of Default (other than an Event of Default specified in Section 501(7) or 501(8)) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in principal amount of the Notes Outstanding may declare the principal amount of all 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 shall become immediately due and payable. If an Event of Default specified in Section 501(7) or 501(8) occurs and is continuing, then the principal amount of all the Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

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

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

Notwithstanding the preceding Paragraph, in the event of a declaration of acceleration in respect of the Notes because of an Event of Default specified in Section 501(5) shall have occurred and be continuing, such declaration of acceleration shall be automatically annulled if the Debt that is the subject of such Event of Default has been discharged or the holders thereof have rescinded their declaration of

acceleration in respect of such Debt, and written notice of such discharge or rescission, as the case may be, shall have been given to the Trustee by the Company and countersigned by the holders of such Debt or a trustee, fiduciary or agent for such holders, within 90 days after such declaration of acceleration in respect of the Notes, and no other Event of Default has occurred during such 90-day period which has not been cured or waived during such period.

SECTION 503 Collection of Indebtedness and Suits for Enforcement by the Trustee.

The Company covenants that if

(a) 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

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

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 shall be legally enforceable, upon any overdue installment of interest, at the rate borne by the 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 and 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 the 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 the Notes, wherever situated.

If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders 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, the Guarantor or any other obligor upon the Notes or the property of the Company, the Guarantor 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 of, 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 and their respective 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 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 to the Holders, to pay 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.

SECTION 505 Trustee May Enforce Claims Without Possession of Notes.

SECTION 506 Application of Money Collected.

Any money 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 on account of principal (or premium, if any) 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 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 Notes for principal (and premium, if any) and interest, respectively; and

THIRD: The balance, if any, to the Person or Persons entitled thereto.

SECTION 507 Limitation on Suits.

No Holder of any Notes 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

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 Guarantor, 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 510 Rights and Remedies Cumulative.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of Section 305, 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 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 511 Delay or Omission Not Waiver.

No delay or omission of the Trustee or of any Holder of any Note 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 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 Holder, as the case may be.

SECTION 512 Control by Holders.

The Holders of not less than a majority in principal amount of the Outstanding Notes 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

(2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and

(3) the Trustee need not take any action which might involve it in personal liability or be unjustly prejudicial to the Holders not consenting.

(1) in respect of the payment of the principal of (or premium, if any) or interest on any Note, or

(2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Note 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; provided, however, that no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon.

SECTION 514 Waiver of Stay or Extension Laws.

Each of the Company and the Guarantor covenant (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 each of the Company and the Guarantor (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.

SECTION 601 Certain Duties and Responsibilities.

The Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee. The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture Act, if applicable. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section.

SECTION 602 Notice of Defaults.

The Trustee shall not be charged with knowledge of a Default or an Event of Default unless a Responsible Officer of the Trustee obtains actual knowledge or receives written notice of such event. Within 90 days after the occurrence of any Default hereunder, the Trustee shall transmit in the manner and to the extent provided in T1A Section 313(c), notice of such Default hereunder known to the Trustee, unless such Default shall have been cured or waived; provided, however, that, except in the case of a Default in the payment of the principal of (or premium, if any) or interest on any Note, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interest of the Holders; and provided further, that in the case of any Default of the character specified in Section 501(3), no such notice to Holders shall be given until at least 30 days after the occurrence thereof.

(6) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company and the Guarantor, personally or by agent or attorney;

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. 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.

SECTION 1002 Maintenance of Office or Agency.

The Company will maintain in the Borough of Manhattan, The City of New York, an office or agency where Notes may be presented or surrendered for payment and where notices and demands to or upon the Company in respect of the Notes, the Guarantee and this Indenture may be served.

SECTION 1003 Money for Note Payments to Be Held in Trust.

If the Company shall at any time act as its own Paying Agent, it will, on or before each due date of the principal of, premium, if any, or interest on any of the Notes, segregate and hold in trust for the benefit of the Persons entitled thereto a slim sufficient to pay the principal of, premium, if any, or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act.

Whenever the Company shall have one or more Paying Agents for the Notes, it will, on or before each due date of the principal of (and premium, if any, on), or interest on, any Notes, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal of, premium or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of such action or any failure so to act.

The Company will cause each Paying Agent (other than the Trustee) to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will:

(1) hold all sums held by it for the payment of the principal of (and premium, if any, on) or interest on Notes in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided;

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of (and premium, if any, on) or interest on any Note and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and an liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in the Borough of Manhattan, The City of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

SECTION 1004 Corporate Existence.

Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect the corporate existence, rights (charter and statutory) and franchises of the Company and its Subsidiaries; provided, however, that the Company shall not be required to preserve any such right or franchise if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries as a whole and that the loss thereof is not disadvantageous in any material respect to the Holders.

SECTION 1005 Maintenance of Properties.

The Company will cause all properties owned by the Company or any Subsidiary of the Company or used or held for use in the conduct of its business or the business of any Subsidiary of the Company to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business

carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent the Company from discontinuing the maintenance of any of such properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business or the business of any Subsidiary of the Company and not disadvantageous in any material respect to the Holders.

SECTION 1006 Insurance.

The Company will at all times keep all of its and its Subsidiaries properties which are of an insurable nature insured with insurers, believed by the Company to be responsible, against loss or damage to the extent that property of similar character is usually so insured by corporations similarly situated and owning like properties.

For purposes of this Section 1007(a), such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture.

(b) When any Default has occurred and is continuing under this Indenture, or if the trustee for or the holder of any other evidence of Debt of the Company or any Subsidiary gives any notice or takes any other action with respect to a claimed default (other than with respect to Debt in the principal amount of less than U.S.$25,000,000), the Company shall deliver to the Trustee an Officers' Certificate specifying such event, notice or other action within ten Business Days of its occurrence unless such Default shall have been cured or waived within such period.

SECTION 1008 Additional Amounts.

All payments made by the Company under or with respect to the Notes will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other governmental charge (including 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 (hereinafter "Taxes"), unless the Company is required to withhold or deduct Taxes by law or by the interpretation or administration thereof. If the Company is required to withhold or deduct any amount for or on account of Taxes from any payment made under or with respect to the Notes, the Company will pay such additional amounts ("Additional Amounts") as may be necessary so that the net amount received by each Holder or owner of a beneficial interest in a global Note (including Additional Amounts) after such withholding or deduction will not be less than the amount such Holder or owner of a beneficial interest in a global Note would have received if such Taxes had not been withheld or deducted; provided, however, that no Additional Amounts will be payable with respect to a payment made to a Holder or owner of a beneficial interest in a global Note (an "Excluded Holder") (i) with which the Company does not deal at arm's length (within the meaning of the Income Tax Act (Canada)) at the time of making such payment, or (ii) which is subject to such Taxes by reason of its being connected with Canada or any province or territory thereof otherwise than solely by reason of the Holder's activity in connection with purchasing the Notes, by the mere holding of Notes or by reason of the receipt of payments thereunder. The Company will also (a) make such withholding or deduction and (b) remit the full amount deducted or withheld to the relevant authority in accordance with applicable law. The Company will furnish the Holders of the Notes within 30 days

after the date the payment of any Taxes is due pursuant to applicable law, certified copies of tax receipts evidencing such payment by the Company. The Company will upon written request of each Holder (other than an Excluded Holder), reimburse each such Holder or owner of a beneficial interest in a global Note, for the amount of (x) any Taxes so levied or imposed and paid by such Holder or owner of a beneficial interest in a global Note as a result of payments made under or with respect to the Notes, and (y) any Taxes so levied or imposed with respect to any reimbursement under the foregoing Clause (x) but excluding any such Taxes on such Xxxxxx's net income so that the net amount received by such Holder (net of payments made under or with respect to the Notes) after such reimbursement will not be less than the net amount the Holder would have received if Taxes on such reimbursement had not been imposed.

At least 30 days prior to each date on which any payment under or with respect to the Notes is due and payable, if the Company will be obligated to pay Additional Amounts with respect to such payment, the Company will deliver to the Trustee an Officers' Certificate stating the fact that such Additional Amounts will be payable and the amounts so payable and will set forth such other information necessary to enable the Trustee to pay such Additional Amounts to Holders on the payment date. Whenever in this Indenture or any Note there is mentioned, in any context, the payment of principal of, premium, if any, Redemption Price, Purchase Price, interest or any other amount payable under or with respect to any Note, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

The obligations of the Company under this Section 1008 shall survive the termination of this Indenture and the payment of all amounts under or with respect to the Notes.

SECTION 1009 Payment of Taxes and Other Claims.

The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (a) all taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary of the Company or upon the income, profits or property of the Company or any Subsidiary of the Company and (b) all lawful claims for labor, materials and supplies, which, if unpaid, might by law become a lien upon the property of the Company or any Subsidiary of the Company; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings.

SECTION 1010 Purchase of Notes upon Change of Control Triggering Event.

(a) Either the Guarantor or the Company will be required to make an Offer to Purchase upon the occurrence of a Change of Control Triggering Event, at a Purchase Price in cash in an amount equal to 101% of the principal amount of the Notes, together with accrued and unpaid interest, if any, to the Purchase Date. For purposes of this Section 1010(a), an Offer to Purchase shall be deemed to have been made if (i) within 30 days following the occurrence of a Change of Control Triggering Event, either the Guarantor or the Company commences an Offer to Purchase Outstanding Notes and (ii) all Notes properly tendered pursuant to such Offer to Purchase are purchased.

(b) The Company or the Guarantor shall perform its obligations specified in the Offer to Purchase. Prior to the Purchase Date, the Company or the Guarantor shall (i) accept for payment Notes or portions thereof tendered pursuant to the Offer, (ii) deposit with the Paying Agent (or, if the Company or the Guarantor is acting as its own Paying Agent, segregate and hold in turn as provided in Section 1003) money sufficient to pay the purchase price of all Notes or portions thereof so accepted and (iii) deliver or cause to be delivered to the Trustee all Notes so accepted together with an Officers' Certificate stating the

Notes or portions thereof accepted for payment by the Company. The Paying Agent shall promptly mail or deliver to Holders of Notes so accepted payment in an amount equal to the Purchase Price, and the Trustee shall promptly authenticate and mail or deliver to such Holders a new Note or Notes equal in principal amount to any unpurchased portion of the Note surrendered as requested by the Holder. Any Note not accepted for payment shall be promptly mailed or delivered by the Company to the Holder thereof . The Company shall publicly announce the results of the Offer on or as soon as practicable after the Purchase Date.

(c) In the event that either the Company or the Guarantor makes an Offer to Purchase pursuant to this Section, the Company or the Guarantor, as the case may be, shall comply with any applicable securities laws and regulations, including any applicable requirements of Section 14(e) of, and Rule 14e-I under, the Securities Exchange Act of 1934, as amended.

(d) The failure of the Company or the Guarantor to make or consummate an Offer to Purchase pursuant to this Section or pay the Purchase Price on the Purchase Date will be deemed to be an Event of Default and will give the Trustee and the Holders the rights described in Article Five.

SECTION 1011 Limitation on Debt.

The Company will not Incur and will not permit any Subsidiary of the Company to Incur any Debt unless, immediately after giving effect to the Incurrence of such Debt and the receipt and application of the proceeds thereof, the Consolidated Cash Flow Ratio for the four full fiscal quarters for which quarterly or annual financial statements are available immediately preceding the Incurrence of such Debt, calculated on a pro forma basis as if such Debt had been Incurred, and proceeds thereof had been applied, at the beginning of such four full fiscal quarters, would be greater than 2.0 to 1 (the "Debt Incurrence Provision").

SECTION 1104 Selection by Trustee of Notes to Be Redeemed.

If less than all the Notes are to be redeemed, the particular Notes to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Notes not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions of the principal of Notes; provided, however, that the Notes will not be redeemed in amounts less than the minimum authorized denomination of U.S.$1,000 and that no such partial redemption shall reduce the portion of the principal amount of a Note not redeemed to less than U.S.$1,000.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to redemption of Notes shall relate, in the case of any Note redeemed or to be redeemed only in part, to the portion of the principal amount of such Note which has been or is to be redeemed.

(6) the place or places where such Notes are to be surrendered for payment of the Redemption Price and accrued interest, if any.

Notice of redemption of Notes to be redeemed at the election of the Company shall be given by the Company or, at the Company's request, by the Trustee in the name and at the expense of the Company.

SECTION 1106 Deposit of Redemption Price.

Prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and accrued interest on, all the Notes which are to be redeemed on that date.

SECTION 1107 Notes Payable on Redemption Date.

Notice of redemption having been given as aforesaid, the Notes so to be redeemed , or portions thereof, shall, on the Redemption Date, become due and payable at the Redemption Price therein specified (together with accrued and unpaid 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, or portions thereof, shall cease to bear interest.

SECTION 1202 Defeasance and Discharge.

Upon the Company's exercise under Section 1201 of the option applicable to this Section 1202, the Company shall be deemed to have been discharged from its obligations with respect to all Outstanding Notes on the date the conditions set forth in Section 1204 are satisfied (hereinafter, "defeasance"). For this purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by the Outstanding Notes, which shall thereafter be deemed to be "Outstanding" only for the purposes of Section 1205 and the other Sections of this Indenture referred to in (A) and (B) below, and to have satisfied all its other obligations under such Notes and this Indenture insofar as such Notes are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (A) the rights of Holders of Outstanding Notes to receive, solely from the trust fund described in Section 1204 and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and interest on such Notes when such payments are due, (B) the Company's rights of redemption and obligations with respect to such Notes under Sections 304, 305, 1002, 1003 and 1008, (C) the rights, powers, trusts, duties and immunities of the Trustees hereunder and (D) this Article Twelve. Subject to compliance with this Article Twelve, the Company may exercise its option under this Section 1202 notwithstanding the prior exercise of its option under Section 1203 with respect to the Notes.

SECTION 1203 Covenant Defeasance.

Upon the Company's exercise under Section 1201 of the option applicable to this Section 1203, the Company shall be released from its obligations under any covenant contained in Section 801 and Section 803 and in Sections 1010 through 1020 with respect to the Outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter, "covenant defeasance"), and the Notes shall thereafter be deemed not to be "Outstanding" for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed "Outstanding" for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to the Outstanding Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 501(4), but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby.

SECTION 1204 Conditions to Defeasance or Covenant Defeasance.

The following shall be the conditions to application of either Section 1202 or Section 1203 to the Outstanding Notes:

(1) The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 607 who shall agree to comply with the provisions of this Article Twelve applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Notes, (A) cash in U.S. dollars in an amount, or (B) U.S. Government Obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a combination thereof, sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, (i) the principal of, premium, if any, and interest on the Outstanding Notes on the Stated Maturity (or Redemption Date, if applicable) of such principal of, premium, if any, or installment of interest and (ii) any payments applicable to the Outstanding Notes on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Notes; provided that the Trustee shall have been irrevocably instructed to apply such money or the proceeds of such U.S. Government Obligations to said payments with respect to the Notes.

The Guarantor hereby irrevocably waives any claim or other rights that it may now or hereafter acquire against the Company that arise from the existence, payment, performance or enforcement of the Guarantor's obligations under this Indenture, or any other document or instrument relating thereto including, without limitation, any right of reimbursement, exoneration, contribution, indemnification, any right to participate in any claim or remedy of the Holders against the Company, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including, without limitation, the right to take or receive from the Company, directly or indirectly, in cash or other property or in any other manner, payment or security on account of such claim or other rights.

Upon the delivery by the Company to the Trustee of an Officers' Certificate and, if requested by the Trustee, an Opinion of Counsel to the effect that the transaction giving rise to the release of such obligations was made by the Company in accordance with the provisions of this Indenture and the Notes, the Trustee shall execute any documents reasonably required in order to evidence the release of the Guarantor from its obligations. If any of the Guaranteed Obligations are revived and reinstated after the termination of the Guarantee, then all of the obligations of the Guarantor under the Guarantee shall be revived and reinstated as if the Guarantee had not been terminated until such time as the Guaranteed Obligations are paid in full, and the Guarantor shall execute any documents reasonably satisfactory to the Trustee evidencing such revival and reinstatement.

(b) Upon the unconditional and full release in writing as provided herein of the Guarantor from all Indebtedness arising hereunder, the Guarantor shall be deemed released from all obligations under this Article; provided, however, that any such termination upon such sale or disposition shall occur if and only to the extent that all obligations of the Guarantor under all of its guarantees of, and under all of its pledges of assets or other security interests which secure, Debt of the Company or any Subsidiary, shall also terminate upon such sale or disposition. Upon the delivery by the Company to the Trustee of an Officers' Certificate and an Opinion of Counsel to the effect that the transaction giving rise to the release of such obligations was made in accordance with the provisions of this Indenture and the Notes, the Trustee shall execute any documents reasonably required in order to evidence the release of the Guarantor from its obligations.

This Indenture may be signed in any number of counterparts each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same Indenture.

SECTION 302. Exchange.

SECTION 303. Book-Entry Provisions for Global Additional Notes.

The Depositary or its nominee shall be the Holder of the Global Additional Notes, and owners of beneficial interests in the Additional Notes represented by the Global Additional Notes shall hold such interests pursuant to the Applicable Procedures. Any such owner's beneficial ownership of any such Additional Notes will be shown only on, and the transfer of such ownership interest shall be effected only through, records maintained by the Depositary or its nominee. Investors in the Regulation S Global Additional Note may hold their interests in the Regulation S Global Additional Note through Euroclear or Clearstream, if they are participants in such systems, or indirectly through organizations which are participants in such systems. After the expiration of the Restricted Period (but not earlier), investors in the Regulation S Global Additional Note may also hold such interests through organizations other than Euroclear or Clearstream that are participants in the Depositary's system. Euroclear and Clearstream will hold interests in the Regulation S Global Additional Note on behalf of their participants through customers' securities accounts in their respective names on the books of their respective depositaries, which, in turn, will hold such interests in the Regulation S Global Additional Note in customers' securities accounts in the depositories' names on the books of the Depositary. All interests in a Global Additional Note, including those held through Euroclear or Clearstream, should be subject to the Applicable Procedures.

(b) Transfers of any Global Additional Note shall be limited to transfers of such Global Additional Note in whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in any Global Additional Note may be transferred in accordance with the rules and procedures of the Depositary and the provisions of this Section 303. Unless (i) the Depositary notifies the Company that it is unwilling or unable to continue as depositary for a Global Additional Note or ceases to be a "Clearing Agency" registered under the Exchange Act or announces an intention permanently to cease business or

(c) Additional Notes issued in exchange for a Global Additional Note or any portion thereof pursuant to the last sentence of subsection (b) of this Section shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Additional Note or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear any legends required hereunder. Any Global Additional Note to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Additional Note to be exchanged in part, either such Global Additional Note shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Additional Note, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Additional Note issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof. In the event of the occurrence of any of the events specified in the last sentence of subsection (b) of this Section 303, the Company will promptly make available to the Trustee a reasonable supply of certificated Additional Notes in definitive form.

(d) Neither the Company nor the Trustee shall have at any time any responsibility or liability to any owner of any beneficial interest in any Additional Note or to any other Person for any error, omission, action or failure to act on the part of the Depositary, Euroclear or Clearstream with respect to payment, when due, to any such owner of the principal, premium, if any, and interest on the Additional Notes, proper recording of beneficial ownership of Additional Notes, proper transfers of such beneficial ownership or any notices to beneficial owners or any other matter of similar or different kind pertaining to the Additional Notes.

The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Security Registrar.

SECTION 401. Guarantee.

Subject to the provisions of this Article, the Guarantor hereby irrevocably and unconditionally guarantees, on a senior basis to each Holder and to the Trustee, for their benefit and the benefit of the Holders, (i) the due and punctual payment of the principal of, premium, if any, and interest on each Additional Note, and any Additional Amounts that may be payable with respect to the Additional Notes, when and as the same shall become due and payable, whether at Stated Maturity or Purchase upon a Change of Control Triggering Event, and whether by declaration of acceleration, a Change of Control Triggering Event, call for redemption or otherwise, the due and punctual payment of interest on the overdue principal of and interest, if any, on the Additional Notes, to the extent lawful, and the due and punctual performance of all other obligations of the Company to the Holders or the Trustee all in accordance with the terms of such Additional Note and this Indenture and (ii) in the case of any extension of time of payment or renewal of any Additional Notes or any of such other obligations, that the same will be promptly paid in full when due or performed in accordance with the terms of the extension or

Without limiting the generality of the foregoing, the Guarantor's liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by the Company to the Holders or the Trustee under the Additional Notes and the Indenture but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving the Company. The Guarantor hereby agrees that its obligations hereunder shall be absolute and unconditional, irrespective of, and shall be unaffected by, any invalidity, irregularity or unenforceability of any such Additional Note or this First Supplemental Indenture, any failure to enforce the provisions of any such Additional Note or this First Supplemental Indenture, any waiver, modification or indulgence granted to the Company with respect thereto, by any Holder or any other circumstances which may otherwise constitute a legal or equitable discharge or defense of the Company or a surety or guarantor.

The Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of merger or bankruptcy of the Company, any right to require a proceeding first against the Company, the benefit of discussion, Protest or notice with respect to any such Additional Note or the Indebtedness evidenced thereby and all demands whatsoever (except as specified above), and covenants that the Guaranteed Obligations will not be discharged as to any such Additional Note except by payment in full of such Guaranteed Obligations and as provided in Sections 401, 1202 and 1305 of the Original Indenture.

The Guarantor further agrees that, as between the Guarantor and the Holders, (i) the maturity of the Guaranteed Obligations may be accelerated as provided in Article Five of the Original Indenture, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Company or in respect of the Guaranteed Obligations, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article Five of the Original Indenture, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by the Company.

The Guarantor hereby irrevocably waives any claim or other rights that it may now or hereafter acquire against the Company that arise from the existence, payment, performance or enforcement of the Guarantor's obligations under this First Supplemental Indenture, or any other document or instrument relating thereto including, without limitation, any right of reimbursement, exoneration, contribution, indemnification, any right to participate in any claim or remedy of the Holders against the Company, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including, without limitation, the right to take or receive from the Company, directly or indirectly, in cash or other property or in any other manner, payment or security on account of such claim or other rights. The Guarantor shall be subrogated to all rights of the Holders of the Additional Notes pursuant to the Guarantee against the Company in respect of any amounts paid by the Guarantor on account of such Additional Note pursuant to the provisions of this Indenture; provided, however, that the Guarantor shall not be entitled to enforce or to receive any payment arising out of, or based upon such right of subrogation until the principal of (and premium, if any) and interest on all Additional Notes issued hereunder shall have been paid in full to the Holders entitled thereto. If

SECTION 402. Obligations of the Company Unconditional.

Nothing contained in this Article, elsewhere in this First Supplemental Indenture or in any Additional Note is intended to or shall impair, as between the Guarantor and the Holders, the obligation of the Guarantor which obligations are independent of the obligations of the Company under the Additional Notes and this First Supplemental Indenture and are absolute and unconditional, to pay to the Holders the Guaranteed Obligations as and when the same shall become due and payable in accordance with the provisions of this First Supplemental Indenture, or is intended to or shall affect the relative rights of the Holders and creditors of the Guarantor, nor shall anything herein or therein prevent the Trustee or any Holder from exercising all remedies otherwise permitted by applicable law upon Default under this First Supplemental Indenture. Each payment to be made by the Guarantor hereunder in respect of the Additional Notes shall be payable in U.S. dollars.

SECTION 403. Ranking of Guarantee.

The Guarantor covenants and agrees, and each Holder of an Additional Note by his acceptance thereof likewise covenants and agrees, that the Guarantee will be an unsecured senior obligation of the Guarantor ranking pari passu in right of payment with all other existing and future Senior Debt of the Company and senior in right of payment to any future Debt of the Guarantor that is expressly subordinated to Senior Debt of the Company. The Guarantee, however, will be effectively subordinated to secured Senior Debt of the Company with respect to any assets of the Guarantor securing such Debt.

SECTION 501. The Trustee.

The Trustee shall not be responsible in any manner whatsoever for, or in respect of, the validity or sufficiency of this First Supplemental Indenture or for, or in respect of, the recitals contained herein, all of which are made solely by the Company and the Guarantor.
