The Trustee is hereby appointed “Security Registrar” for the purpose of the registration of Securities and of transfer of Securities in the Security Register as herein provided. The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register for each series of Securities issued hereunder (hereinafter collectively referred to as the “Security Register”) in which, subject to such reasonable regulations at it may prescribe, the Company shall provide for the registration of Securities and the transfer of Securities as in this Article Three provided. The Security Register shall be in written form or in any other form capable of being converted into written form within a reasonable time. Upon due presentment for registration of transfer of any Security of any series at such office or agency, the Company shall execute and the Trustee shall register,

authenticate and deliver in the name of the transferee or transferees a new Security or Securities of the same series for an equal aggregate principal amount.

All Securities presented for registration of transfer or for exchange, redemption or payment shall (if so required by the Company or the Security Registrar) be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the registered Holder or his attorney duly authorized in writing.

No service charge shall be made for any exchange or registration of transfer of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

The Company shall not be required to exchange or register the transfer of (a) any Securities of any series for a period of 15 days preceding the first mailing or publication of notice of redemption of Securities of such series to be redeemed, or (b) any Securities selected, called or being called for redemption except, in the case of any Security to be redeemed in part, the portion thereof not so to be redeemed.

SECTION 3.06. Mutilated, Destroyed, Lost or Stolen Securities. In case any temporary or definitive Security shall become mutilated or be destroyed, lost or stolen, the Company in the case of a mutilated Security shall, and in the case of a lost, stolen or destroyed Security may in its discretion, execute, and upon its request the Trustee shall authenticate and deliver, a new Security of the same series bearing a number, letter or other distinguishing symbol not contemporaneously outstanding, in exchange and substitution for the mutilated Security, or in lieu of and in substitution for the Security so destroyed, lost or stolen, or if any such Security shall have matured or shall be about to mature, instead of issuing a substituted Security, the Company may pay or authorize the payment of the same without surrender thereof (except in the case of a mutilated Security). In every case the applicant for a substituted Security shall furnish to the Company and to the Trustee such security or indemnity as may be required by them to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company and to the Trustee evidence to their satisfaction of the destruction, loss or theft of such Security and of the ownership thereof.

The Trustee may authenticate any such substituted Security and deliver the same upon the written request or authorization of any Officer of the Company. Upon the issuance of any substituted Security, 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 connected therewith and in addition a further sum not exceeding two dollars for each Security so issued in substitution.

Every substituted Security issued pursuant to the provisions of this Section 3.06 by virtue of the fact that any Security is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be found at any time, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder. All Securities shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities and shall preclude

(to the extent lawful) any and all other rights or remedies with respect to the replacement or payment of negotiable instruments or other securities without their surrender.

SECTION 3.07. Temporary Securities. Pending the preparation of definitive Securities of any series the Company may execute and the Trustee shall authenticate and deliver temporary Securities (printed or lithographed). Temporary Securities shall be issuable in any authorized denomination and substantially in the form of the definitive Securities but with such omissions, insertions and variations as may be appropriate for temporary Securities, all as may be determined by the Company. Every such temporary Security shall be executed by the Company and shall be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the definitive Securities. Without unreasonable delay the Company will execute and deliver to the Trustee definitive Securities of such series and thereupon any or all temporary Securities of such series may be surrendered in exchange therefore, at the Corporate Trust Office of the Trustee, and the Trustee shall authenticate and deliver in exchange for such temporary Securities an equal aggregate principal amount of definitive Securities. Such exchange shall be made by the Company at its own expense and without any charge therefor except that in case of any such exchange involving any registration of transfer the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities authenticated and delivered hereunder.

If the Company shall establish pursuant to Section 3.01 that the Securities of a series are to be issued in whole or in part in the form of one or more Global Securities, then the Company shall execute and the Trustee shall, in accordance with Section 3.03 and the Company Order with respect to such series, authenticate and deliver one or more Global Securities in temporary or permanent form that (i) shall represent and shall be denominated in an amount equal to the aggregate principal amount of the Outstanding Securities of such series to be represented by one or more Global Securities, (ii) shall be registered in the name of the Depositary for such Global Security or Securities or the nominee of such depositary, and (iii) shall bear a legend substantially to the following effect: “This Security may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary, unless and until this Security is exchanged in whole or in part for Securities in definitive form” and such other legend as may be required by the Depositary.

Notwithstanding any other provision of this Section or Section 3.05, unless and until it is exchanged in whole or in part for Securities in definitive form, a Global Security representing all or a portion of the Securities of a series may not be transferred except as a whole by the Depositary for such series to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor Depositary for such series or a nominee of such successor depositary.

If at any time the Depositary for the Securities of a series notifies the Company that it is unwilling or unable to continue as Depositary for the Securities of such series or if at any time the Depositary for Securities of a series shall no longer be a clearing agency registered and in good standing under the Securities Exchange Act of 1934, as amended, or other applicable

statute or regulation, the Company shall appoint a successor Depositary with respect to the Securities of such series. If a successor Depositary for the Securities of such series is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such condition, the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Securities of such series, will authenticate and deliver, Securities of such series in definitive form in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such series in exchange for such Global Security or Securities.

The Company may at any time and in its sole discretion determine that the Securities of any series issued in the form of one or more Global Securities shall no longer be represented by such Global Security or Securities. In such event, the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Securities of such series, will authenticate and deliver, Securities of such series in definitive form and in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such series in exchange for such Global Security or Securities.

If the Securities of any series shall have been issued in the form of one or more Global Securities and if an Event of Default with respect to the Securities of such series shall have occurred and be continuing, the Company will promptly execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Securities of such series, will authenticate and deliver Securities of such series in definitive form and in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such series in exchange for such Global Security or Securities.

If specified by the Company pursuant to Section 3.01 with respect to Securities of a series, the Depositary for such series of Securities may surrender a Global Security for such series of Securities in exchange in whole or in part for Securities of such series in definitive form on such terms as are acceptable to the Company and such depositary. Thereupon, the Company shall execute and the Trustee shall authenticate and deliver, without charge:

(1) to each Person specified by the Depositary a new Registered Security or Securities of the same series, of any authorized denomination as requested by such Person in an aggregate principal amount equal to and in exchange for such Person’s beneficial interest in the Global Security; and

(2) to the Depositary a new Global Security in a denomination equal to the difference, if any, between the principal amount of the surrendered Global Security and the aggregate principal amount of Securities delivered to Holders thereof.

Upon the exchange of a Global Security in whole for Securities in definitive form, such Global Security shall be cancelled by the Trustee. Securities so issued in exchange for a Global Security shall be registered in such names and in such authorized denominations as the Depositary for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Securities to the Persons in whose names such Securities are so registered.

SECTION 3.08. Payment of Interest; Interest Rights Preserved. Interest on any Security 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 that Security is registered at the close of business on the Regular Record Date for such interest.

Any interest on any Security which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date or within 30 days thereafter (herein called “Defaulted Interest”) shall forthwith cease to be payable to the registered Holder on the relevant Regular Record Date by virtue of having been such Holder; and such 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 Securities are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date 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 mailed, first-class postage prepaid, to each Holder at his address as it appears in the Security Register not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in a newspaper, customarily published in the English language on each Business Day and of general circulation in the Borough of Manhattan, The City of New York, but such publication shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names the Securities are registered 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 Securities may be listed, and upon such notice as may be required by such exchange, if after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall

carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

SECTION 3.09. Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee, the Authenticating Agent and any agent of the Company or the Trustee may treat the Person in whose name the Security is registered as the owner of such Security for the purpose of receiving payment of principal of, and (subject to Section 3.08) interest on, such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee, the Authenticating Agent nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

SECTION 3.10. Cancellation. All Securities 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 any such Securities and Securities surrendered directly to the Trustee for any such purpose shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of by the Trustee in its customary manner.

SECTION 3.11. Computation of Interest. Except as otherwise specified as contemplated by Section 3.01 for Securities of any Series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months.

SECTION 3.12. CUSIP Numbers. The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the “CUSIP” numbers.

ARTICLE FOUR

SATISFACTION AND DISCHARGE

SECTION 4.01. Satisfaction and Discharge of Indenture. This Indenture shall cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Securities herein expressly provided for), and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when:

(1) either:

(A) all Securities theretofore authenticated and delivered (other than (i) Securities which have been destroyed, lost or stolen and which have been

replaced or paid as provided in Section 3.06 and (ii) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 10.03) have been delivered to the Trustee for cancellation; or

(B) all such Securities not theretofore delivered to the Trustee for cancellation:

(i) have become due and payable, or

(ii) will become due and payable at their Stated Maturities within one year, or

(iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company,

and the Company in the case of (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal (and premium, if any) and interest to the date of such deposit (in the case of Securities that have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be;

(2) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 6.07 and the obligations of the Trustee to any Authenticating Agent under Section 6.14 shall survive such satisfaction and discharge.

SECTION 4.02. Application of Trust Money. All money deposited with the Trustee pursuant to Section 4.01 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

SECTION 4.03. Repayment to Company. The Trustee and each Paying Agent shall promptly pay to the Company upon request any excess money (1) deposited with them pursuant to Section 4.02 and (2) held by them at any time.

The Trustee and each Paying Agent shall pay to the Company upon request any money held by them for the payment of principal or interest that remains unclaimed for two years after a right to such money has matured; provided, however, that the Trustee or such Paying Agent, before being required to make any such payment, may at the expense of the Company cause to be mailed to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein, which shall be at least 30 days from the date of such mailing, any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Holders entitled to money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person.

SECTION 4.04. Reinstatement. If the Trustee or any Paying Agent is unable to apply any money in accordance with Section 4.02 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 4.01 until such time as the Trustee or such Paying Agent is permitted to apply all such money in accordance with Section 4.02; provided, however, that if the Company has made any payment of the principal of or interest on any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive any such payment from the money held by the Trustee or such Paying Agent.

ARTICLE FIVE

REMEDIES

SECTION 5.01. Events of Default.

“Events of Default”, wherever used herein with respect to Securities of any series, means any one of the following events and such other events as may be established with respect to the Securities of that series as contemplated by Section 3.01 hereof (whatever the reasons for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(a) the Company defaults in the payment of any interest on any Security when the same becomes due and payable and the default continues for a period of 30 days; or

(b) the Company defaults in the payment of any principal of (including, without limitation, any premium, if any, on) any Security when the same becomes due and payable (whether at maturity, upon redemption or otherwise); or

(c) the Company fails to comply with any of its other agreements contained in the Securities or this Indenture and the default continues for the period and after the notice specified below;

(d) the commencement by the Company or any Significant Subsidiary of the Company of a voluntary case or proceeding under any applicable U.S. federal or state bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by the Company or

any Significant Subsidiary to the entry of a decree or order for relief in respect of the Company or any Significant Subsidiary of the Company in an involuntary case or proceeding under any applicable U.S. federal or state bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against the Company or any Significant Subsidiary of the Company, or the filing by the Company or any Significant Subsidiary of the Company of a petition or answer or consent seeking reorganization or relief under any applicable U.S. federal or state law, or the consent by the Company or any Significant Subsidiary of the Company to the filing of such petition or to the appointment of or the taking possession by a custodian of the Company or any Significant Subsidiary of the Company or of any substantial part of their properties, or the making by the Company or any Significant Subsidiary of the Company of an assignment for the benefit of creditors, or the admission by the Company or any Significant Subsidiary of the Company in writing of their inability to pay its debts generally as they become due, or the taking of corporate action by the Company or any Significant Subsidiary of the Company expressly in furtherance of any such action.

A default under clause (c) above is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee in writing of the default, and the Company does not cure the default within 60 days after receipt of such notice. The notice given pursuant to this Section 5.01 must specify the default, demand that it be remedied and state that the notice is a “Notice of Default.” When any default under this Section 5.01 is cured, it ceases.

The Trustee shall not be charged with knowledge of any Event of Default unless written notice thereof shall have been given to a Trust Officer at the Corporate Trust Office of the Trustee by the Company, a Paying Agent, any Holder or any agent of any Holder.

SECTION 5.02. Acceleration.

If an Event of Default (other than an Event of Default specified in clause (d) of Section 5.01) occurs and is continuing, the Trustee may, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may, by notice to the Company and the Trustee, declare all unpaid principal to the date of acceleration on the Securities then outstanding (if not then due and payable) to be due and payable upon any such declaration, and the same shall become and be immediately due and payable. If an Event of Default specified in clause (d) of Section 5.01 occurs, all unpaid principal of the Securities then outstanding 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. The Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may rescind an acceleration and its consequences if (a) all existing Events of Default, other than the nonpayment of the principal of the Securities which has become due solely by such declaration of acceleration, have been cured or waived; (b) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; (c) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (d) all payments due to the Trustee and any predecessor Trustee under Section 6.07 have been made. No such rescission shall affect any subsequent default or impair any right consequent thereto.

SECTION 5.03. Other Remedies.

If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy by proceeding at law or in equity to collect the payment of the principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law.

SECTION 5.04. Waiver of Defaults and Events of Default. Subject to Section 9.02, the Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may waive an existing default or Event of Default and its consequence, except a default or Event of Default in the payment of the principal of, premium, if any, or interest on any Security or any default or Event of Default in respect of any provision of this Indenture or the Securities which, under Section 9.02, cannot be modified or amended without the consent of the Holder of each Security affected. When a default or Event of Default is waived, it is cured and ceases.

SECTION 5.05. Control by Majority. The Holders of a majority in aggregate principal amount of the Securities then outstanding may 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 it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Holder or the Trustee, or that may involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to it; provided, however, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

SECTION 5.06. Limitations on Suits. A Holder may not pursue any remedy with respect to this Indenture or the Securities (except actions for payment of overdue principal or interest) unless:

(1) the Holder gives to the Trustee written notice of a continuing Event of Default;

(2) the Holders of at least 25% in aggregate principal amount of the then outstanding Securities make a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer to the Trustee reasonable indemnity to the Trustee against any loss, liability or expense;

(4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and

(5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the Securities then outstanding.

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over such other Holder.

SECTION 5.07. Collection Suit by Trustee. If an Event of Default in the payment of principal or interest specified in clause (a) or (b) of Section 5.01 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or another obligor on the Securities for the whole amount of principal and accrued interest remaining unpaid, together with, to the extent that payment of such interest is lawful, interest on overdue principal and on overdue installments of interest, in each case at the rate per annum borne by the Securities and 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.

SECTION 5.08. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and 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 the Holders allowed in any judicial proceedings relative to the Company (or any other obligor on the Securities), its creditors or its property and shall be entitled and empowered to collect and receive any money or other property payable or deliverable on any such claims and to distribute the same, and any receiver, trustee, assignee, 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 to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.07, and to the extent that such payment of the reasonable compensation, expenses, disbursements and advances in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other property which the Holders may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to, or, on behalf of any Holder, to authorize, accept or adopt any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 5.09. Priorities. If the Trustee collects any money pursuant to this Article Five, it shall pay out the money in the following order:

First, to the Trustee for amounts due under Section 6.07;

Second, to Holders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and

Third, the balance, if any, to the Company.

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 5.09.

SECTION 5.10. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 5.10 does not apply to a suit made by the Trustee or a suit by Holders of more than 10% in aggregate principal amount of the Securities then outstanding.

ARTICLE SIX

THE TRUSTEE

SECTION 6.01. Certain Duties and Responsibilities.

(a) Except during the continuance of an Event of Default,

(1) the Trustee undertakes to perform such duties, and only such duties, as are specifically set forth in this Indenture or the Trust Indenture Act, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they substantially conform to the requirements of this Indenture (but needs not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

(b) In case an Event of Default actually known to a Responsible Officer of the Trustee with respect to the Securities of a series has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture with respect to such series, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

(c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(1) this Subsection shall not be construed to limit the effect of Subsection (a) of this Section;

(2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

(3) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders pursuant to Section 5.05 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; and

(4) 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.

(d) The Trustee shall not be obligated to pay interest on any money or other assets received by it unless otherwise agreed with the Company. Assets held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(e) 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 6.02. Notice of Defaults.

Within 90 days after the occurrence of any Default with respect to the Securities of any series, the Trustee shall transmit by mail to all Holders of Securities of that Series, as their names and addresses appear in the Security Register, notice of all Defaults with respect to that Series actually known to a Responsible Officer of the Trustee, unless such Defaults shall have been cured or waived before the giving of such notice; 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 of the Securities of such series, the Trustee shall be protected in withholding such notice if and so long as the Board of Directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders.

SECTION 6.06. Money Held in Trust.

If such corporation publishes reports of condition at least annually, pursuant to law or to requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. Neither the Company nor any Person directly or indirectly controlling, controlled by, or under the common control with the Company shall serve as Trustee for the Securities. If at any time the Trustee shall cease to be eligible in accordance

with the provisions of this Section, it shall resign immediately in the manner and with the effect hereunder specified in this Article.

SECTION 6.10. Resignation and Removal; Appointment of Successor.

(a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee under Section 6.11.

(b) The Trustee may resign at any time with respect to one or more or all series of Securities by giving written notice thereof to the Company. If an instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

(c) The Holders of a majority in aggregate principal amount of the Securities of one or more series (each series voting as a class) or all series at the time Outstanding may at any time remove the Trustee with respect to the applicable series or all series, as the case may be, and by written notice of such action to the Company, the Trustee and the successor Trustee, nominate with respect to the applicable series or all series, as the case may be, a successor Trustee, which shall be deemed appointed as successor Trustee with respect to the applicable series unless within ten days after such nomination the Company objects thereto, in which case the Trustee so removed or any Holder of Securities of the applicable series who has been a bona fide holder of a Security or the applicable series for at least six months may, subject to the provisions of Section 5.09 on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to such series.

(d) If at any time:

(1) the Trustee shall fail to comply with Section 310(b) of the Trust Indenture Act pursuant to Section 6.08 hereof after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, unless the Trustee’s duty to resign is stayed in accordance with the provisions of Section 310(b) of the Trust Indenture Act, or

(2) the Trustee shall cease to be eligible under Section 6.09 and shall fail to resign after written request therefor by the Company or by any such Holder, or

(3) the Trustee shall become incapable of acting, or a decree or order for relief by a court having jurisdiction in the premises shall have been entered in respect of the Trustee in an involuntary case under the Federal bankruptcy laws, as now or hereafter constituted, or any other applicable Federal or State, bankruptcy, insolvency or similar law; or a decree or order by a court having jurisdiction in the premises for the appointment of a receiver or custodian or liquidator or trustee or assignee in bankruptcy or insolvency of the Trustee or of its property, or for the winding up of its affairs shall have been entered, or

(4) the Trustee shall commence a voluntary case under the Federal bankruptcy laws, as now or hereafter constituted, or any other applicable Federal or State bankruptcy, insolvency or similar law, or shall consent to the appointment of a receiver or custodian or liquidator or trustee or assignee in bankruptcy or insolvency of it or of its property, or shall make an assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due, or corporate action shall be taken by the Trustee in furtherance of any such action,

then, in any such case, (i) the Company by a Board Resolution may remove the Trustee, or (ii) subject to Section 5.09, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee to the vacated office. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee with respect to the Securities of such series and supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders and accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.

SECTION 6.11. Acceptance of Appointment by Successor.

Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee, and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder, subject nevertheless to its lien, if any, provided for in Section 6.07. Upon request of any such successor Trustee, the Company shall

execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts.

In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the predecessor Trustee and each successor Trustee with respect to the Securities of any applicable series shall execute and deliver an indenture supplemental hereto which shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the predecessor Trustee with respect to the Securities of any series as to which the predecessor Trustee is not retiring shall continue to be vested in the predecessor Trustee, and shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such trustees, co-trustees of the same trust and that each trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such trustee.

No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

SECTION 6.12. Merger, Conversion, Consolidation or Succession to Business.

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 (including the administration of the trust created by this Indenture), 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 Security shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

SECTION 6.13. Preferential Collection of Claims Against Company.

The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein.

SECTION 6.14. Appointment of Authenticating Agent.

At any time when any of the Securities remain Outstanding the Trustee may appoint an Authenticating Agent or Agents which shall be authorized to act on behalf of the Trustee to authenticate Securities issued upon exchange, transfer or partial redemption thereof or pursuant to Section 3.06, and Securities 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. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to

include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a bank or trust company or corporation organized and doing business and in good standing under the laws of the United States of America, or of any State, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $1,500,000 and subject to supervision or examination by Federal or State authorities. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

Any corporation 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 succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may at any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice of termination to such Authenticating Agent 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 mail notice of such appointment to all Holders, as their names and addresses appear on the Security Register. 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 herein. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section.

If an appointment is made pursuant to this Section, the Securities shall have endorsed thereon, in addition to the Trustee’s Certificate, an alternate Trustee’s Certificate in the following form:

This is one of the Securities described in the within-mentioned Indenture.

(j) to add or modify any other provisions with respect to matters or questions arising under this Indenture which the Company and the Trustee may deem necessary or desirable; provided, however, that such action pursuant to this clause (j) does not, in the good faith opinion of the Board of Directors of the Company (as evidenced by a Board Resolution) and the Trustee, adversely affect the interests of any Holder of Securities in any material respect; or

(k) to modify the covenants or Events of Default solely in respect of, or add new covenants or Events of Default that apply solely to, Securities not Outstanding on the date of such supplemental indenture.

The Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any property thereunder, but the Trustee shall not be obligated to, but may in its discretion, enter

into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise.

Any supplemental indenture authorized by the provisions of this Section 9.01 may be executed by the Company and the Trustee without the consent of the Holders of any of the Securities at the time Outstanding, notwithstanding any of the provisions of Section 9.02.

SECTION 9.02. Supplemental Indentures and Waiver with Consent of Holders. With the consent (evidenced as provided in Section 1.02) of the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of each series affected by such supplemental indenture (each series voting separately as a class), the Company, when authorized by a Board Resolution, and the Trustee may from time to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Securities of each such series; and the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of each series affected by such waiver (each series voting separately as a class) may waive the Company’s compliance with any of the provisions of this Indenture or of any supplemental indenture; provided, however, that no such supplemental indenture or waiver shall, without the consent of the Holder of each affected Security, (i) change the Stated Maturity of any Security, or reduce the rate or change the time of payment of interest thereon, or reduce the principal amount thereof or any premium thereon, or make the principal thereof or interest or premium thereon payable in any coin or currency other than that provided in the Securities or impair the right to institute suit for enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or adversely affect the right of repayment, if any, at the option of the Holder or (ii) reduce the aforesaid percentage of Securities, the Holders of which are required to consent to any such supplemental indenture, or the Holders of which are required for any waiver (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture without the consent of the Holder of each Security. A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series.

Upon the request of the Company, accompanied by a Board Resolution authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture.

It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed supplemental indenture or waiver, but it shall be sufficient if such consent shall approve the substance thereof.

SECTION 9.03. Compliance with Trust Indenture Act; Effect of Supplemental Indentures. Any supplemental indenture executed pursuant to the provisions of this Article Nine shall comply with the Trust Indenture Act of 1939, as then in effect. Upon the execution of any supplemental indenture pursuant to the provisions of this Article Nine, this Indenture shall be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company, and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

SECTION 9.04. Notation on Securities. Securities authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article Nine may bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company or the Trustee shall so determine, new Securities of any series so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may be prepared and executed by the Company, authenticated by the Trustee and delivered in exchange for the Securities of such series then Outstanding.

SECTION 9.05. Evidence of Compliance of Supplemental Indenture to be Furnished Trustee.

The Trustee, subject to the provisions of Section 6.01, shall be provided with an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto complies with the requirements of this Article Nine.

ARTICLE TEN

COVENANTS

SECTION 10.01. Payment of Principal and Interest.

The Company will duly and punctually pay or cause to be paid the principal of, premium, if any, and interest, if any, on the Securities in accordance with the terms of the Securities and this Indenture.

SECTION 10.02. Maintenance of Office or Agency.

The Company shall maintain an office or agency where Securities may be presented or surrendered for payment and an office or agency where Securities may be surrendered for transfer or exchange and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Corporate Trust Office of the Trustee shall be such office of the Company, and the Trustee shall be the agent of the Company for all of the foregoing purposes, unless the Company shall designate and maintain some other office or agency for such purposes and give the Trustee written notice of the location thereof. The Company will give prompt written notice to the Trustee of any change in the location of any such office or agency. If at any time the Company shall fail to maintain any such required office

or agency, the Corporate Trust Office of the Trustee shall be conclusively deemed to be the agency of the Company for all such purposes.

SECTION 10.03. Money for Security 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 or premium, if any, or interest on, any of the Securities, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal or 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 it will, on each due date of the principal of or interest on, any Securities, deposit with a Paying Agent a sum sufficient to pay the principal or 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 or premium, if any, or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or 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 or premium, if any, or interest on Securities 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;

(2) give the Trustee notice of any default by the Company (or any other obligor upon the Securities) in the making of any payment of principal or premium, if any, or interest; and

(3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

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 money.

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 or premium, if any, or interest on any Security and remaining unclaimed for two years after such principal or 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 Security 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 all 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 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 10.04. Compliance Certificates.

The Company shall deliver to the Trustee, within 90 days after the end of each fiscal year of the Company (beginning with the fiscal year ending December 31, 20 ), an Officers’ Certificate as to the signer’s knowledge of the Company’s compliance with all conditions and covenants on its part contained in this Indenture and stating whether or not the signer knows of any Default or Event of Default. If such signer knows of such a Default or Event of Default, the Officers’ Certificate shall describe the Default or Event of Default and the efforts to remedy the same. For the purposes of this Section 10.04, compliance shall be determined without regard to any grace period or requirement of notice provided pursuant to the terms of this Indenture.

SECTION 10.05. 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 its corporate existence.

SECTION 10.06. Waiver of Certain Covenants.

The Company may omit in any particular instance to comply with any covenant or condition set forth in Section 10.05 or any covenant added for the benefit of any series of Securities as contemplated by Section 3.01, if before or after the time for such compliance the Holders of at least a majority in principal amount of the Securities of such series at the time Outstanding shall, by Act of such Holders, waive such compliance in such instance, but no such waiver shall extend to or affect such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such covenant or condition shall remain in full force and effect.

ARTICLE ELEVEN

REDEMPTION OF SECURITIES

SECTION 11.01. Applicability of Article. The provisions of this Article shall be applicable to the Securities of any series that are redeemable before their maturity except as otherwise specified as contemplated by Section 3.01 for Securities of such series.

SECTION 11.02. Notice of Redemption; Selection of Securities. In case the Company shall desire to exercise the right to redeem all, or, as the case may be, any part of the Securities of any series in accordance with their terms, it shall fix a date for redemption and shall mail or cause to be mailed a notice of such redemption at least 20 and not more than 60 days prior to the date fixed for redemption to the Holders of Securities of such series so to be redeemed as a whole or in part at their last addresses as the same appear on the Security Register. Such mailing shall be by first class mail. The notice if mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Security of a series designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Security of such series.

Each such notice of redemption shall include CUSIP numbers and specify the date fixed for redemption, the redemption price at which Securities of such series are to be redeemed, the place or places of payment, that payment will be made upon presentation and surrender of such Securities, that any interest accrued to the date fixed for redemption will be paid as specified in said notice, and that on and after said date any interest thereon or on the portions thereof to be redeemed will cease to accrue. If less than all the Securities of a series are to be redeemed the notice of redemption shall specify the numbers of the Securities of that series to be redeemed. In case any Security of a series is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that on and after the date fixed for redemption, upon surrender of such Security, a new Security or Securities of that series in principal amount equal to the unredeemed portion thereof will be issued.

On the redemption date specified in the notice of redemption given as provided in this Section 11.02, the Company will deposit with the Trustee or with one or more paying agents an amount of money sufficient to redeem on the redemption date all the Securities or portions thereof so called for redemption at the appropriate redemption price, together with accrued interest to the date fixed for redemption.

If all or less than all the Securities of a series are to be redeemed, the Company will give the Trustee notice not less than 60 days prior to the redemption date (unless a shorter period is acceptable to the Trustee) as to the aggregate principal amount of Securities to be redeemed and the Trustee shall select, in such manner as in its sole discretion it shall deem appropriate, the Securities of that series or portions thereof (in multiples of $1,000, except as otherwise set forth in the applicable form of Security) to be redeemed.

SECTION 11.03. Payment of Securities Called for Redemption. If notice of redemption has been given as provided in Section 11.02, the Securities or portions of Securities of the series with respect to which such notice has been given shall become due and payable on the date and at the place or places stated in such notice at the applicable redemption price, together with any interest accrued to the date fixed for redemption, and on and after said date (unless the Company shall default in the payment of such Securities at the applicable redemption price, together with any interest accrued to said date) any interest on the Securities or portions of Securities of any series so called for redemption shall cease to accrue. On presentation and surrender of such Securities at a place of payment in said notice specified, the said Securities or the specified portions thereof shall be paid and redeemed by the Company at the applicable redemption price, together with any interest accrued thereon to the date fixed for redemption.

Upon presentation of any Security redeemed in part only, the Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Company, a new Security or Securities of such series, of authorized denominations, in principal amount equal to the unredeemed portion of the Security so presented.

ARTICLE TWELVE

Miscellaneous

SECTION 12.01. Form of Documents Delivered to Trustee.

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

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

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

SECTION 12.02. Notices.

Any notice or communication by the Company or the Trustee to the others is duly given if in writing and delivered in Person or mailed by first class mail (registered or certified, return receipt requested), telex, telecopier or overnight air courier guaranteeing next day delivery, to the others’ address.

The Company or the Trustee, by notice to the others may designate additional or different addresses for subsequent notices or communications.

All notices and communications (other than those sent to Holders) shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when answered back, if telexed; when receipt acknowledged, if telecopied; and the next Business Day after timely delivery to the courier, if sent by overnight air courier guaranteeing next day delivery; provided, however, that any notice of communication to the Trustee shall not be deemed to be received by it until actually received by it at the Corporate Trust Office of the Trustee.

Any notice or communication to a Holder shall be mailed by first class mail, certified or registered, return receipt requested, or by overnight air courier guaranteeing next day delivery to its address shown on the register kept by the Security Registrar. Any notice or communication shall also be so mailed to any Person described in TIA § 313(c), to the extent required by the TIA. Failure to mail a notice or communication to a Holder or any defect in it shall not affect its sufficiency with respect to other Holders.

If a notice or communication addressed to a party other than the Trustee is mailed in the manner provided above within the time prescribed, it is duly given, whether or not the addressee receives it.

If the Company mails a notice or communication to Holders, it shall mail a copy to the Trustee and each Agent at the same time.

SECTION 12.03. Notice to Holders; Waiver.

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

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

SECTION 12.04. Trust Indenture Act Controls.

If any provision hereof limits, qualifies or conflicts with the duties imposed by any of Section 310 through 317, inclusive, of the Trust Indenture Act through the operation of Section 318(c) thereof, such imposed duties shall control.

SECTION 12.05. Certificate and Opinion as to Conditions Precedent.

Upon any application or request by the Company to the Trustee to take any action under any provision of this Indenture, the Company shall, upon the request of the Trustee, furnish to the Trustee:

(1) an Officers’ Certificate in form and substance reasonably satisfactory to the Trustee (which shall include the statements set forth in Section 12.06 hereof) stating that, in the opinion of the signers, all conditions precedent and covenants, if any, provided for in this Indenture relating to the proposed action have been satisfied; and

(2) an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee (which shall include the statements set forth in Section 12.06 hereof) stating that, in the opinion of such counsel, all such conditions precedent and covenants, if any, have been satisfied, except that in the case of any such application or request as to which the furnishing of such documents is specifically required by any provision of this Indenture

relating to such particular application or request, no additional certificate or opinion need be furnished.

SECTION 12.06. Statements Required in Certificate or Opinion.

Each certificate (other than certificates provided pursuant to Section 10.04) or opinion with respect to compliance with a condition or covenant provided for in this Indenture shall include:

(1) a statement that the Person making such certificate or opinion has read such covenant or condition;

(2) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

(3) a statement that, in the opinion of such Person, he or she has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not such covenant or condition has been satisfied; and

(4) a statement as to whether, in the opinion of such Person, such condition or covenant has been satisfied.

SECTION 12.07. Table of Contents, Headings, etc..

The Table of Contents, Cross-Reference Table and Headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and shall in no way modify or restrict any of the terms or provisions hereof.

SECTION 12.08. Successors and Assigns.

All covenants and agreements in this Indenture by the Company and the Securities shall bind its successors and assigns, whether so expressed or not. All covenants and agreements in this Indenture by the Trustee and the Securities shall bind its successors and assigns, whether so expressed or not

SECTION 12.09. Separability Clause.

In case any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable, then, to the extent permitted by applicable law, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 12.10. Benefits of Indenture.

Nothing in this Indenture or in the Securities, express or implied, shall give to any Person (other than the parties hereto, any Security Registrar, any Paying Agent, any Authenticating Agent, and their successors hereunder, and the Holders of Securities) any benefit or any legal or equitable right, remedy or claim under this Indenture.

SECTION 12.11. Rules by Trustee and Agents..

The Trustee may make reasonable rules for action by or at a meeting of Holders. The Security Registrar or Paying Agent may make reasonable rules and set reasonable requirements for its functions.

SECTION 12.12. No Personal Liability of Directors, Officers, Employees and Stockholders..

No past, present or future director, officer, employee, incorporator or stockholder of the Company or Person controlling such Persons, as such, shall have any liability for any obligations of the Company or of any Person controlling such Person under the Securities or this Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Securities by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Securities. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the Commission that such a waiver is against public policy.

SECTION 12.13. Governing Law.

This Indenture and the Securities shall be governed by, and construed in accordance with, the laws of the State of New York.

SECTION 12.14. Legal Holidays.

In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day, then (notwithstanding any other provision of this Indenture or the Security) payment of interest or principal need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity, and no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be.

SECTION 12.15. Indenture and Securities Solely Corporate Obligations.

No recourse for the payment of principal of or interest on any Security or for any claim based on any Security or this Indenture shall be had against any director or officer or stockholder, past, present or future, of the Company. Any such claim against any such Person is expressly waived as a condition of, and as consideration for, the execution and delivery of this Indenture and the issue of the Securities.

SECTION 12.16. No Security Interest Created.

Nothing in this Indenture or in the Securities, expressed or implied, shall be construed to constitute a security interest under the Uniform Commercial Code or similar legislation, as now or hereafter enacted and in effect, in any jurisdiction where property of the Company or its Subsidiaries is located.

SECTION 12.17. Counterpart Originals.

The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.

SECTION 12.18. No Adverse Interpretation of Other Agreements.

This Indenture may not be used to interpret any other Indenture, loan or debt agreement of the Company or its Subsidiaries or of any other Person. Any such Indenture, loan or debt agreement may not be used to interpret this Indenture.

* * * * * *

This instrument may be executed 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 instrument.

In Witness Whereof, the parties hereto have caused this Indenture to be duly executed, all as of the day and year first above written.
