     (a) A Global Security deposited with the Depositary or with the Trustee as custodian for the Depositary pursuant to Section 2.01 shall be transferred to the beneficial owners thereof in the form of certificated Securities in an aggregate principal amount equal to the principal amount of such Global Security, in exchange for such Global Security, only if such transfer complies with Section 2.06 and (i) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for such Global Security or if at any time such Depositary ceases to be a “clearing agency” registered under the Exchange Act and a successor depositary is not appointed by the Company within 90 days of such notice or cessation, or (ii) the Company, in its sole discretion and subject to the procedures of the Depositary, notifies the Trustee in writing that it elects to cause the issuance of certificated Securities under this Indenture.

     (b) Any Global Security that is transferred to the beneficial owners thereof pursuant to this Section shall be surrendered by the Depositary to the Trustee at its office located in the Borough of Manhattan, The City of New York, to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Global Security, an equal aggregate principal amount of certificated Securities of authorized denominations. Any portion of a Global Security transferred pursuant to this Section shall be executed, authenticated and delivered only in denominations of $1,000 and any integral multiple thereof and registered in such names as the Depositary shall direct. Any certificated Security delivered in exchange for an interest in the Global Security shall, except as otherwise provided by Section 2.06(b)(ii), bear the restricted securities legend set forth in Section 2.06(b).

     (c) Subject to the provisions of Section 2.06(b), the registered Holder of a Global Security may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities.

     (d) If any of the events specified in Section 2.07(a) occurs, the Company shall promptly make available to the Trustee a reasonable supply of certificated Securities in definitive, fully registered form without interest coupons.

     (e) If a certificated Security issued pursuant to this Section 2.07 is exchanged for another certificated Security, such Securities may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of (i) Section 2.06(a)(iii) (including the certification and other requirements set forth on the reverse of the Securities intended to ensure that such transfers comply with Rule 144A or Regulation S, as the case may be, or are otherwise in compliance with the requirements of the Securities Act) and such other procedures as may from time to time be adopted by the Company and (ii) Section 2.06(b).

     Section 2.08 Replacement Securities

     If any mutilated Security is surrendered to the Trustee, or the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, the Company shall issue and the Trustee shall authenticate a replacement Security, but only if the

14

Trustee’s requirements are met. If required by the Trustee or the Company, such Holder must furnish an indemnity bond that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent or any authenticating agent from any loss which any of them may suffer if a Security is replaced. The Company and the Trustee may charge for their expenses in replacing a Security. If, after the delivery of such replacement Security, a bona fide purchaser of the original Security in lieu of which such replacement Security was issued presents for payment or registration such original Security, the Trustee shall be entitled to recover such replacement Security from the Person to whom it was delivered or any Person taking therefrom, except a bona fide purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Trustee or the Company in connection therewith.

     Every replacement Security is an additional obligation of the Company.

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

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

     Section 2.09 Outstanding Securities

     The Securities outstanding at any time are all the Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Security effected by the Trustee hereunder and those described in this Section 2.09 as not outstanding; provided, however, that in determining whether the holders of the requisite principal amount of outstanding Securities are present at a meeting of holders of Securities for quorum purposes or have consented to or voted in favor of any request, demand, authorization, direction, notice, consent, waiver, amendment or modification hereunder, Securities held for the account of the Company, any of its Subsidiaries or any of their respective Affiliates shall be disregarded and deemed not to be outstanding, except that in determining whether the Trustee shall be protected in making such a determination or relying upon any such quorum, consent or vote, only Securities which a Responsible Officer of the Trustee actually knows to be so owned shall be so disregarded.

     If a Security is replaced pursuant to Section 2.08 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser.

     If the principal amount of any Security is considered paid under Section 3.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

     A Security does not cease to be outstanding because the Company or any of its Affiliates holds the Security.

15

     Section 2.10 Treasury Securities

     In determining whether the Holders of the required principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company or any of its Affiliates shall be disregarded, except that for the purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities which a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded.

     Section 2.11 Temporary Securities

     Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities, but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities in exchange for temporary Securities. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities.

     Section 2.12 Cancellation

     The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel all Securities surrendered for registration of transfer, exchange, payment, replacement or cancellation. All canceled Securities held by the Trustee shall be disposed of in accordance with the usual disposal procedures of the Trustee. The Company may not issue new Securities to replace Securities that have been paid or that have been delivered to the Trustee for cancellation.

     Section 2.13 Defaulted Interest

     If the Company defaults in a payment of interest on the Securities, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest on the defaulted interest, in each case at the rate provided in the Securities and in Section 3.01 hereof. The Company may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. At least 15 days before any special record date, the Company (or the Trustee, in the name of and at the expense of the Company) shall mail to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

     Section 2.14 Persons Deemed Owners

     The Company, the Trustee, any Agent and any authenticating agent may treat the Person in whose name any Security is registered as the owner of such Security for the purpose of receiving payments of principal of or premium, if any, or (subject to the record date provisions hereof) interest on such Security and for all other purposes. None of the Company, the Trustee, any Agent or any authenticating agent shall be affected by any notice to the contrary.

16

     Section 2.15 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 shall promptly notify the Trustee of any change in the “CUSIP” numbers.

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

17

Borough of Manhattan, The City of New York for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 2.03 hereof.

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of the covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

     (b) In addition, whether or not required by the rules and regulations of the SEC, the Company shall file a copy of all such information and reports with the SEC for public availability (unless the SEC will not accept such filing).

Upon any such declaration the amounts due and payable on the Securities, as determined in accordance with the next succeeding paragraph, shall be due and payable immediately. If an Event of Default specified in clause (4) or (5) of Section 5.01 hereof occurs, the principal of and premium, if any, and accrued and unpaid interest on all Securities then outstanding shall ipso facto become and be immediately due and payable without any declaration, notice or other act on the part of the Trustee or any Holder.

25

     At any time after such a declaration of acceleration with respect to the Securities has been made and before a judgment for payment of the money due has been obtained by the Trustee as hereinafter in this Article V provided, the Holders of a majority in principal amount of the outstanding Securities, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if:

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

     (A) all overdue interest on all Securities,

     (B) the principal of (and premium, if any, on) any Securities which have become due otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities or in this Indenture,

     (C) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in the Securities or in this Indenture, and

     (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel;

and

     (2) all Events of Default, other than the non-payment of the principal of Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.04.

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

     If the maturity of the Securities is accelerated pursuant to this Section 5.02, 100% of the principal amount thereof shall become due and payable plus premium, if any, and accrued interest to the date of payment.

     Section 5.03 Other Remedies

     If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, or premium, if any, 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. All remedies are cumulative to the extent permitted by law.

26

     Section 5.04 Waiver of Existing Defaults

     Subject to Sections 5.07 and 8.02 hereof, the Holders of a majority in principal amount of the outstanding Securities by notice to the Trustee may waive an existing Default or Event of Default and its consequences (including waivers obtained in connection with a tender offer or exchange offer for the Securities or a solicitation of consents in respect of the Securities, provided that in each case such offer or solicitation is made to all Holders of the Securities then outstanding on equal terms), except (1) a continuing Default or Event of Default in the payment of the principal of, or premium, if any, or interest on the Securities or (2) a continuing Default in respect of a provision that under Section 8.02 hereof cannot be amended without the consent of each Holder affected. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

     Section 5.05 Control by Majority

     The Holders of a majority in 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 hereunder. However, the Trustee may refuse to follow any direction that conflicts with applicable law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of other Holders, or that may involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

     Section 5.06 Limitations on Suits

     Subject to Section 5.07 hereof, a Holder may pursue a remedy with respect to this Indenture or the Securities only if:

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

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

     (3) such Holder or Holders offer to the Trustee indemnity satisfactory 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) during such 60-day period the Holders of a majority in principal amount of the Securities do not give the Trustee a direction inconsistent with the request.

27

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

     Section 5.07 Rights of Holders to Receive Payment

     Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of principal of, and premium, if any, and interest on the Security, on or after the respective due dates expressed or provided for in the Security, or to bring suit for the enforcement of any such payment on or after such respective dates, is absolute and unconditional and shall not be impaired or affected without the consent of such Holder.

     Section 5.08 Collection Suit by Trustee

     If an Event of Default specified in clause (1) or (2) of Section 5.01 hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the amount of principal and premium, if any, and interest remaining unpaid on the Securities, and interest on overdue principal, premium, if any, to the extent lawful, interest on overdue interest 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 5.09 Trustee May File Proofs of Claim

     The Trustee is authorized to file such proofs of claim and other papers or documents and to take such actions, including participating as a member, voting or otherwise, of any committee of creditors, 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 its creditors or properties and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any Custodian 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 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.07 hereof out of the estate in any such proceeding, 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 properties which the Holders may be entitled to receive in such proceeding 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 accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

28

     Section 5.10 Priorities

     If the Trustee collects any money pursuant to this Article, it shall pay out the money in the following order:

                First: to the Trustee for amounts due under Section 6.07 hereof;

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

                Third: to the Company.

     The Trustee, upon prior written notice to the Company, may fix a record date and payment date for any payment to Holders pursuant to this Article.

     Section 5.11 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 a 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 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 5.07 hereof, or a suit by a Holder or Holders of more than 10% in principal amount of the Securities then outstanding.

ARTICLE VI

TRUSTEE

     Section 6.01 Duties of Trustee

     (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in such exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

     (h) The permissive right of the Trustee to take the actions permitted by this Indenture shall not be construed as an obligation or duty to do so.

31

it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee is subject to Sections 6.10 and 6.11 hereof.

     Section 6.04 Trustee’s Disclaimer

     The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities or any money paid to the Company or upon the Company’s direction under any provision hereof, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee and it shall not be responsible for any statement or recital herein or any statement in the Securities other than its certificate of authentication.

     Section 6.05 Notice of Defaults

     If a Default or Event of Default occurs and is continuing and it is actually known to a Responsible Officer of the Trustee, the Trustee shall mail to Holders a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, or premium, if any, or interest on any Security, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of Holders.

     On or before July 15 of each year, beginning with July 15, 2005, the Trustee shall mail to Holders a brief report dated as of a date convenient to the Trustee no more than 60 nor less than 45 days prior thereto, that complies with TIA Section 313(a); provided, however, that if no event described in TIA Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted. The Trustee also shall comply with TIA Section 313(b). The Trustee shall also transmit by mail all reports as required by TIA Sections 313(c) and 313(d).

     A copy of each report at the time of its mailing to Holders shall be filed with the SEC and each securities exchange, if any, on which the Securities are listed. The Company shall notify the Trustee if and when the Securities are listed on any stock exchange or delisted therefrom.

     Section 6.07 Compensation and Indemnity

     The Company agrees to pay to the Trustee from time to time such compensation as agreed to by the Company and the Trustee, for its acceptance of this Indenture and its services hereunder. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company agrees to reimburse the Trustee upon request for all reasonable disbursements, advances and expenses incurred by it. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

     The Company agrees to fully indemnify the Trustee or any predecessor Trustee and their agents for and to hold them harmless against any and all loss, liability damage, claims, or expense (including taxes, other than taxes based upon, measured by or determined by the income of the Trustee) incurred by it arising out of or in connection with the acceptance or

32

administration of its duties under this Indenture, including the costs and expenses of defending itself against any claim (whether asserted by the Company, any Holder or any other Person), except as set forth in the next paragraph. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel, and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

     The Company shall not be obligated to reimburse any expense or indemnify against any loss or liability incurred by the Trustee through its own negligence or bad faith.

     To secure the payment obligations of the Company in this Section 6.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal of, and premium, if any, and interest and on particular Securities. Such lien shall survive the satisfaction and discharge of this Indenture.

     Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee incurs expenses or renders services after an Event of Default specified in Section 5.01(4) or (5) hereof occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law.

     The obligations of the Company under this Section shall survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee.

     Section 6.08 Replacement of Trustee

     A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 6.08.

     The Trustee may resign and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in principal amount of the then outstanding Securities may remove the Trustee by so notifying the Trustee and the Company. The Company may remove the Trustee if:

     (1) the Trustee fails to comply with Section 6.10 hereof;

     (2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

     (3) a Custodian or public officer takes charge of the Trustee or its property; or

     (4) the Trustee otherwise becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the Securities

33

then outstanding may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

     If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of at least 10% in principal amount of the Securities then outstanding may petition (at the expense of the Company) any court of competent jurisdiction at the expense of the Company for the appointment of a successor Trustee.

     If the Trustee fails to comply with Section 6.10 hereof, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

     A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 6.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 6.08 hereof, the obligations of the Company under Section 6.07 hereof shall continue for the benefit of the retiring Trustee.

     Section 6.09 Successor Trustee by Merger, etc

     Subject to Section 6.10 hereof, if the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee; provided, however, that in the case of a transfer of all or substantially all of its corporate trust business to another corporation, the transferee corporation expressly assumes all of the Trustee’s liabilities hereunder.

     In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have.

     Section 6.10 Eligibility; Disqualification

     There shall at all times be a Trustee hereunder which shall be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia and authorized under such laws to exercise corporate trust power, shall be subject to supervision or examination by federal or State (or the District of Columbia) authority and shall have, or be a Subsidiary of a bank or bank holding company having, a combined capital and surplus of at least $50 million as set forth in its most recent published annual report of condition.

34

     This Indenture shall always have a Trustee who satisfies the requirements of TIA Sections 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee is subject to and shall comply with the provisions of TIA Section 310(b) during the period of time required by this Indenture. Nothing in this Indenture shall prevent the Trustee from filing with the SEC the application referred to in the penultimate paragraph of TIA Section 310(b). For purposes of clause (i) of the proviso to TIA Section 310(b), the following indentures are specifically described: the Senior Indenture dated as of July 15, 1996 between the Company and JPMorgan Chase Bank, N.A., as successor trustee, the Senior Indenture dated as of January 16, 1998 between the Company and JPMorgan Chase Bank, N.A., as successor trustee, the Indenture dated as of August 17, 2001 between the Company and JPMorgan Chase Bank, N.A., as successor trustee, and the Indenture dated as of July 3, 2002 between the Company and JPMorgan Chase Bank, N.A., as successor trustee.

     Subject to the requirements of any applicable abandoned property laws, the Trustee and the Paying Agent shall pay to the Company upon written request any money held by them for the payment of principal, premium, if any, or interest that remains unclaimed for two years after the date upon which such payment shall have become due; provided, however, that the Company shall have either caused notice of such payment to be mailed to each Holder entitled thereto no less than 30 days prior to such repayment or within such period shall have published such notice in a financial newspaper of widespread circulation published in The City of New York. After payment to the Company, Holders entitled to the money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another Person, and all liability of the Trustee and the Paying Agent with respect to such money shall cease.

     Section 7.04 Reinstatement

     If the Trustee or the Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with Section 7.01 hereof 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, the obligations of the Company under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 7.01 hereof until such time as the Trustee or the Paying Agent is permitted to apply all such money or U. S. Government Obligations in accordance with Section 7.01 hereof; provided, however, that if the Company has made any payment of 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 such payment from the money or U.S. Government Obligations held by the Trustee or the Paying Agent.

ARTICLE VIII

AMENDMENTS

     Section 8.01 Without Consent of Holders

     The Company and the Trustee may amend or supplement this Indenture or any of the Securities or waive any provision hereof or thereof without the consent of any Holder:

     (1) to cure any ambiguity, omission, defect or inconsistency;

     (2) to comply with Sections 4.01 and 4.02 hereof;

     (3) to provide for uncertificated Securities in addition to or in place of certificated Securities;

     (4) to add any additional Events of Default;

38

     (5) to add to, change or eliminate any of the provisions of this Indenture to such extent as shall be necessary to permit or facilitate the issuance of Securities in bearer form, registrable or not registrable as to principal, and with or without interest coupons;

     (6) to provide for the acceptance of appointment hereunder of a successor trustee in compliance with the provisions hereof;

     (7) to secure the Securities pursuant to the requirements of Section 3.05 or otherwise;

     (8) to comply with any requirement in order to effect or maintain the qualification of this Indenture under the TIA;

     (9) to comply with any requirements of the SEC in connection with qualifying this Indenture under the TIA;

     (10) to add to the covenants of the Company for the benefit of the Holders or to surrender any right or power herein conferred upon the Company; or

     (11) to make any change that does not adversely affect the rights hereunder of any Holder in any material respect.

     Upon the request of the Company accompanied by a resolution of the Board of Directors of the Company authorizing the execution of any such supplemental indenture, and upon receipt by the Trustee of the documents described in Section 8.06 hereof, the Trustee shall join with the Company in the execution of any supplemental indenture authorized or permitted by the terms of this Section and make any further appropriate agreements and stipulations that may be therein contained. After an amendment, supplement or waiver under this Section 8.01 becomes effective, the Company shall mail to the Holders of each Security affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture.

     Section 8.02 With Consent of Holders

     Except as provided below in this Section 8.02, the Company and the Trustee may amend or supplement this Indenture or the Securities with the written consent (including consents obtained in connection with a tender offer or exchange offer for the Securities or a solicitation of consents in respect of the Securities, provided that in each case such offer or solicitation is made to all Holders of the Securities then outstanding on equal terms) of the Holders of at least a majority in principal amount of the Securities then outstanding.

     Upon the request of the Company accompanied by a resolution of the Board of Directors of the Company authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 8.06 hereof, the Trustee shall join with the Company in the execution of such supplemental indenture.

39

     It shall not be necessary for the consent of the Holders under this Section 8.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.

     The Holders of a majority in principal amount of the Securities then outstanding may waive compliance in a particular instance by the Company with any provision of this Indenture or the Securities (including waivers obtained in connection with a tender offer or exchange offer for the Securities or a solicitation of consents in respect of the Securities, provided that in each case such offer or solicitation is made to all Holders of the Securities then outstanding on equal terms).

     Without the consent of each Holder affected, an amendment, supplement or waiver under this Section may not:

     (1) reduce the percentage of principal amount of the Securities whose Holders must consent to an amendment, supplement or waiver;

     (2) reduce the rate of or change the time for payment of interest, including default interest, on any Security;

     (3) reduce the principal of or change the fixed maturity of any Security or alter the premium or other provisions with respect to redemption under Section 9.07 or specified in the Securities;

     (4) change the place of payment or make any Security payable in money other than that stated in the Security;

     (5) impair the right to institute suit for the enforcement of any payment of principal of, or premium, if any, or interest on any Security pursuant to Sections 5.07 and 5.08 hereof, except as limited by Section 5.06 hereof;

     (6) make any change in the percentage of principal amount of the Securities necessary to waive compliance with certain provisions of this Indenture pursuant to Section 5.04 or 5.07 hereof or this clause of this Section 8.02; or

     (7) waive a continuing Default or Event of Default in the payment of principal of, or premium, if any, or interest on the Securities.

     Section 8.03 Compliance with Trust Indenture Act

     Every amendment to this Indenture or the Securities shall comply in form and substance with the TIA as then in effect.

     Section 8.04 Revocation and Effect of Consents

     A consent to an amendment (which includes a supplement) or waiver by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the

40

consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to his or her Security or portion of a Security if the Trustee receives written notice of revocation at any time prior to (but not after) the date the Trustee receives an Officers’ Certificate certifying that the Holders of the requisite principal amount of Securities have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

     The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment or waiver or to take any other action under this Indenture. If a record date is fixed, then notwithstanding the provisions of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment, supplement or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No consent shall be valid or effective for more than 90 days after such record date unless consents from Holders of the principal amount of the Securities required hereunder for such amendment or waiver to be effective shall have also been given and not revoked within such 90-day period.

     After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it is of the type described in any of clauses (1) through (7) of Section 8.02 hereof. In such case, the amendment or waiver shall bind each Holder who has consented to it and every subsequent Holder that evidences the same debt as the consenting Holder’s Security.

     Section 8.05 Notation on or Exchange of Securities

     If an amendment changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment.

     Section 8.06 Trustee to Sign Amendments, etc.

     The Trustee shall sign any amendment, waiver or supplemental indenture authorized pursuant to this Article if the amendment, waiver or supplemental indenture does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign it. In signing or refusing to sign such amendment, waiver or supplemental indenture, the Trustee shall receive, and subject to Section 6.01 hereof, shall be fully protected in relying upon, an Opinion of Counsel and an Officers’ Certificate, as conclusive evidence that such amendment, waiver or supplemental indenture is authorized or permitted by this Indenture, that it is not inconsistent herewith, and that it will be valid and binding upon the Company in accordance with its terms.

ARTICLE IX

REDEMPTION

     Section 9.01 Notices to Trustee

     If the Company elects to redeem Securities pursuant to the redemption provisions of Section 9.07, it shall furnish to the Trustee, at least 45 days but not more than 60 days before a Redemption Date (unless the Trustee consents in writing to a shorter period of at least 30 days prior to the Redemption Date), an Officers’ Certificate setting forth the Redemption Date, the principal amount of such Securities to be redeemed and the Redemption Price.

     Section 9.02 Selection of Securities to be Redeemed

     If less than all of the Securities are to be redeemed, the Trustee shall select the Securities to be redeemed by such method as the Trustee in its sole discretion shall deem appropriate. The particular Securities to be redeemed shall be selected, unless otherwise provided herein, not less than 30 days nor more than 60 days prior to the Redemption Date by the Trustee from the outstanding Securities not previously called for redemption.

     The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Security selected for partial redemption, the principal amount thereof to be redeemed. Securities and portions of them selected shall be in amounts of $1,000 or whole multiples of $1,000. Except as provided in the preceding sentence, provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption.

     Section 9.03 Notices to Holders

     (a) At least 30 days but not more than 60 days before a Redemption Date, the Company shall mail in conformity with Section 10.02 a notice of redemption to each Holder whose Securities are to be redeemed.

     The Notice shall identify the Securities to be redeemed (including CUSIP numbers, if any) and shall state:

     (i) the Redemption Date;

     (ii) the Redemption Price, or if not yet known, the manner in which it will be calculated;

     (iii) if any Security is being redeemed in part, the portion of the principal amount of such Security to be redeemed and that, after the Redemption Date, upon surrender of such Security, a new Security or Securities in principal amount equal to the unredeemed portion will be issued;

     (iv) the name and address of the Paying Agent;

42

     (v) that Securities called for redemption must be surrendered to the Paying Agent at the address specified in such notice to collect the Redemption Price;

     (vi) that unless the Company defaults in making the redemption payment, interest on Securities called for redemption ceases to accrue on and after the Redemption Date and the only remaining right of the Holders is to receive payment of the Redemption Price upon surrender to the Paying Agent of the Securities; and

     (vii) the aggregate principal amount of Securities being redeemed.

     If any of the Securities to be redeemed is in the form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depositary applicable to redemptions.

     The Trustee shall not be responsible for the calculation of the Redemption Price. The Company shall notify the Trustee of the Redemption Price promptly after the calculation thereof.

     (b) At the Company’s request, the Trustee shall give the notice required in Section 9.03(a) in the Company’s name; provided, however, that the Company shall deliver to the Trustee, at least 45 days prior to the Redemption Date (unless the Trustee consents in writing to a shorter period at least 30 days prior to the Redemption Date), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 9.03(a).

     Section 9.04 Effect of Notices of Redemption

     Once notice of redemption is mailed pursuant to Section 9.03, Securities called for redemption become due and payable on the Redemption Date at the Redemption Price. Upon surrender to the Paying Agent, such Securities shall be paid out at the Redemption Price.

     Section 9.05 Deposit of Redemption Price

     At or prior to 11:00 am New York City time on the Redemption Date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the Redemption Price of all Securities to be redeemed on that date. The Trustee or the Paying Agent shall return to the Company any money not required for that purpose less the expenses of the Trustee as provided herein.

     If the Company complies with the preceding paragraph, interest on the Securities or portions thereof to be redeemed (whether or not such Securities are presented for payment) will cease to accrue on the applicable Redemption Date. If any Security called for redemption shall not be so paid upon surrender because of the failure of the Company to comply with the preceding paragraph, then interest will be paid on the unpaid principal and premium, if any, from the Redemption Date until such principal and premium are paid and, to the extent lawful, on any interest not paid on such unpaid principal, in each case at the rate provided in the Securities and in Section 3.01.

43

     Section 9.06 Securities Redeemed in Part

     Upon surrender of a Security that is redeemed in part, the Company shall issue and the Trustee shall authenticate for the Holder, at the expense of the Company, a new Security equal in principal amount to the unredeemed portion of the Security surrendered.

     Section 9.07 Optional Redemption

     The Securities may be redeemed at any time, at the option of the Company, in whole or from time to time in part, at the Redemption Price specified in such Securities.

     Any redemption pursuant to this Section 9.07 shall be made, to the extent applicable, pursuant to the provisions of Sections 9.01 through 9.06.

[REVERSE OF SECURITY]

TRANSCONTINENTAL GAS PIPE LINE CORPORATION

Floating Rate Senior Note due April 15, 2008

     This Security is one of a duly authorized issue of Floating Rate Senior Notes due April 15, 2008 (the “Securities”) of Transcontinental Gas Pipe Line Corporation, a Delaware corporation (the “Company”).

     1. Interest. Interest on this Security will accrue from the most recent Interest Payment Date (as set forth on the face of this Security, each an "Interest Payment Date”) to which interest has been paid or duly provided for or, if no interest has been paid or duly provided for, from the Initial Issue Date. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, subject to certain exceptions described herein, be paid to the person in whose name this Security (or one or more predecessor Securities) is registered at the close of business on the Record Date (as set forth on the face of this Security, each a “Record Date”) immediately prior to an Interest Payment Date (whether or not a Business Day); provided, however, that interest payable on the Stated Maturity Date (or any Redemption Date) will be payable to the person to whom the principal hereof shall be payable.

     If an Interest Payment Date (other than the Stated Maturity Date or a Redemption Date) would fall on a day that is not a Business Day, such Interest Payment Date shall be the following day that is a Business Day, except if such Business Day falls in the next calendar month, such Interest Payment Date shall be the immediately preceding day that is a Business Day. If the Stated Maturity Date or a Redemption Date falls on a day that is not a Business Day, payment of principal and interest due on that date shall be made on the following day that is a Business Day and no interest shall accrue for the period from and after the Stated Maturity Date or such Redemption Date, as the case may be, on the payment so deferred.

     This Security will bear interest at the rate determined in accordance with the applicable provisions below by reference to the Three-Month LIBOR Rate (as defined below) plus 1.28%. Commencing with the Initial Interest Reset Date specified on the face hereof, the rate at which interest on this Security is payable shall be reset as of each Interest Reset Date (as used herein, the term "Interest Reset Date” shall include the Initial Interest Reset Date). The Interest Reset Dates will be the Interest Reset Dates specified on the face hereof; provided, however, that (i) the interest rate in effect for the period from the Initial Issue Date to the Initial Interest Reset Date specified on the face hereof will be [                   ]% (the “Initial Interest Rate”) and (ii) the interest rate in effect hereon for the 15 days immediately prior to the Stated Maturity Date hereof (or, with respect to any principal amount to be redeemed or repaid, any Redemption Date) shall be that in effect on the 15th day preceding the Stated Maturity Date hereof or such date of redemption, as the case may be. If any Interest Reset Date would otherwise be a day that is not a Business Day, such Interest Reset Date shall be postponed to the next succeeding day that is a Business Day, except if such Business Day falls in the next calendar month, such Interest Reset Date shall be the immediately preceding day that is a Business Day.

A-4

     The “Three-Month LIBOR Rate” with respect to this Security shall be determined on the second London Banking Day (as defined below) preceding each Interest Reset Date (each date, an “Interest Determination Date”) as follows:

     (i) As of the Interest Determination Date, JPMorgan Chase Bank, N.A., in its capacity as calculation agent (the “Calculation Agent”), shall determine the arithmetic mean of the offered rates for deposits in U.S. dollars for the three-month period commencing on the applicable Interest Reset Date that appears on Telerate Page 3750 (defined below) at approximately 11:00 a.m., London time, on such Interest Determination Date.

     (ii) If this rate does not appear on Telerate Page 3750, the Calculation Agent will determine the rate on the basis of the rates at which deposits in U.S. dollars are offered by four major banks in the London interbank market (selected by the Calculation Agent) at approximately 11:00 a.m., London time, on such Interest Determination Date to prime banks in the London interbank market for a period of three months commencing on that Interest Reset Date and in a principal amount equal to an amount not less than U.S. $1,000,000 that is representative for a single transaction in such market at such time. In such case, the Calculation Agent will request the principal London office of each of the aforesaid major banks to provide a quotation of such rate. If at least two such quotations are provided, the rate for that Interest Reset Date will be the arithmetic mean of the quotations, and, if fewer than two quotations are provided as requested, the rate for that Interest Reset Date will be the arithmetic mean of the rates quoted by three major banks in New York City (selected by the Calculation Agent) at approximately 11:00 a.m., New York City time, on such Interest Determination Date for loans in U.S. dollars to leading European banks for a period of three months commencing on that Interest Reset Date and in a principal amount equal to an amount not less than U.S. $1,000,000 that is representative for a single transaction in such market at such time.

     (iii) if the banks so selected by the Calculation Agent are not quoting as set forth above, the Three-Month LIBOR Rate for that Interest Determination Date shall be the Three-Month LIBOR Rate already in effect on the day preceding the applicable Interest Reset Date, or in the case of the Initial Interest Reset Date, the Initial Interest Rate.

     A “London Banking Day” is any day in which dealings in U.S. dollars are transacted in the London interbank market.

     “Telerate Page 3750” means the display page so designated on the Moneyline Telerate, Inc. (or such other page as may replace such page on that service or any successor service for the purpose of displaying London interbank offered rates of major banks).

     The interest rate on this Security will in no event be higher than the maximum rate permitted by New York law, as the same may be modified by United States law of general application.

A-5

     At the request of the Holder hereof, the Calculation Agent will provide to the Holder hereof the interest rate hereon then in effect and, if determined, the interest rate that will become effective as of the next Interest Reset Date.

     Interest payments on this Security will include interest accrued to but excluding the Interest Payment Dates or the Stated Maturity Date (or any Redemption Date), as the case may be.

     Accrued interest hereon shall be an amount calculated by multiplying the face amount hereof by an accrued interest factor. Such accrued interest factor shall be computed by adding the interest factor calculated for each day in the period for which interest is being paid. The interest factor for each such date shall be computed by dividing the interest rate applicable to such day by 360. All percentages resulting from any calculation of the rate of interest on this Security will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point (0.0000001), with five one-millionths of a percentage point rounded upward, and all dollar amounts used in or resulting from such calculation on this Security will be rounded to the nearest cent (with one-half cent rounded upward). The interest rate in effect on any Interest Reset Date will be the applicable rate as reset on such date. The interest rate applicable to any other day is the interest rate from the immediately preceding Interest Reset Date (or, if none, the Initial Interest Rate).

     2. Method of Payment. The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered Holders of Securities at the close of business on the Record Date next preceding the Interest Payment Date (whether or not a Business Day), even if such Securities are canceled after such Record Date and on or before such Interest Payment Date. The Holder must surrender this Security to a Paying Agent to collect payments of principal and premium, if any. The Company will pay the principal of, and premium, if any, and interest on the Securities in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company will make all payments in respect of a certificated Security (including principal, premium, if any, and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

     3. Ranking. The Securities are senior unsecured obligations of the Company.

     4. Optional Redemption. The Securities may be redeemed at any time, at the option of the Company, in whole or from time to time in part, at a price equal to the greater of (i) 100% of the principal amount of the Securities then outstanding to be redeemed, or (ii) the sum of the present values of the remaining scheduled payments of the principal amount to be redeemed and interest thereon (assuming that the Three-Month LIBOR Rate through the Stated Maturity Date

A-6

of the Securities would remain constant as of the Redemption Date), exclusive of accrued but unpaid interest to the Redemption Date, discounted to the Redemption Date on a bond-equivalent yield basis (assuming a 360-day year consisting of twelve 30-day months) and at a rate per annum equal to the Three-Month LIBOR Rate as of the Redemption Date plus 25 basis points (0.25%), plus in each case, accrued and unpaid interest to the Redemption Date (the “Redemption Price”).

     Periodic interest installments with respect to which the Interest Payment Date is prior to any Redemption Date will be payable to Holders of record at the close of business on the relevant Record Dates referred to herein, all as provided in the Indenture.

     Notice of redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of Securities to be redeemed at his registered address. Securities in denominations larger than $1,000 may be redeemed in part but only in whole multiples of $1,000. On or after the Redemption Date interest will cease to accrue on Securities or on the portions thereof called for redemption, as the case may be.

     The Trustee shall not be responsible for the calculation of the Redemption Price. The Company shall notify the Trustee of the Redemption Price promptly after the calculation thereof.

     5. Paying Agent, Registrar and Calculation Agent. Initially, JPMorgan Chase Bank, N.A. (the “Trustee”), the Trustee under the Indenture, will act as Paying Agent, Registrar and Calculation Agent. The Company may change any Paying Agent, Registrar, Calculation Agent, co-registrar or additional paying agent without notice to any Holder. The Company or any of its subsidiaries may act in any such capacity.

     6. Indenture. The Company issued the Securities under an Indenture dated as of December 17, 2004 (as amended, supplemented or otherwise modified form time to time, the “Indenture”) between the Company and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb), as in effect on the date of execution of the Indenture (the “TIA”). The Securities are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. The Securities are unsecured general obligations of the Company. Capitalized terms used but not defined in this Security have the respective meanings given to such terms in the Indenture.

     7. Denominations, Transfer, Exchange. The Securities are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not exchange or register the transfer of any Securities during the period between a Record Date and the corresponding Interest Payment Date.

     8. Persons Deemed Owners. Except as set forth in the Indenture, the registered Holder of a Security shall be treated as its owner for all purposes.

A-7

     9. Amendments and Waivers. Subject to certain exceptions and limitations, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the then outstanding Securities, and compliance in a particular instance by the Company with any provision of the Indenture may be waived (other than certain provisions, including any continuing Default or Event of Default in the payment of the principal of, or premium, if any, or interest on the Securities) by the Holders of at least a majority in principal amount of the Securities then outstanding in accordance with the terms of the Indenture. Without the consent of any Holder, the Company and the Trustee may amend or supplement the Indenture or the Securities to cure any ambiguity, omission, defect or inconsistency; to comply with the Indenture in the case of the merger, consolidation or sale or other disposition of the assets of the Company substantially as an entirety; to provide for uncertificated Securities in addition to or in place of certificated Securities; to add any additional Events of Default; to provide for the acceptance under the Indenture of a successor trustee in compliance with the provisions thereof; to secure the Securities pursuant to the requirements under the Indenture; to comply with any requirements in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act of 1939, as amended; to comply with any requirements of the SEC in connection with qualifying the Indenture under the TIA; to add to the covenants of the Company for the benefit of the Holders or to surrender any power conferred upon the Company; or to make any change that does not adversely affect the rights of any Holder in any material respect.

     Without the consent of each Holder affected, the Company may not (i) reduce the percentage of principal amount of Securities whose Holders must consent to an amendment, supplement or waiver, (ii) reduce the rate of or change the time for payment of interest, including default interest, on any Security, (iii) reduce the principal of or change the fixed maturity of any Security or alter the premium or other provisions with respect to redemption, (iv) change the place of payment or make any Security payable in money other than that stated in the Security, (v) impair the right to institute suit for the enforcement of any payment of principal of, or premium, if any, or interest on any Security, (vi) make any change in the percentage of principal amount of Securities necessary to waive compliance with certain provisions of the Indenture or (vii) waive a continuing Default or Event of Default in the payment of principal of, or premium, if any, or interest on the Securities.

     10. Defaults and Remedies. Events of Default include: default in payment of interest on the Securities for 30 days; default in payment of principal of, or premium, if any, on the Securities; default in the performance, or breach, of any of its other covenants, warranties or agreements in the Indenture by the Company for 90 days after written notice by the Trustee or by the Holders of at least 25% of the aggregate principal amount of the Securities then outstanding; certain voluntary or involuntary events involving bankruptcy, insolvency or reorganization of the Company. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Securities may declare the principal of, and premium, if any, and interest on all the Securities to be immediately due and payable, except that in the case of an Event of Default arising from certain events of bankruptcy, insolvency or reorganization of the Company, all outstanding Securities become due and payable immediately without further action or notice. The amount due and payable upon the acceleration of any Security is equal to 100% of the principal amount thereof plus premium, if any, and accrued interest to the date of payment. Holders may not enforce the Indenture or the Securities except

A-8

as provided in the Indenture. The Trustee may require indemnity reasonably satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal or premium, if any, or interest) if it determines that withholding notice is in their interests. The Company must furnish an annual compliance certificate to the Trustee.

     11. Discharge Prior to Maturity. The Indenture shall be discharged and canceled upon the payment of all of the Securities and shall be discharged except for certain obligations upon the irrevocable deposit with the Trustee of funds or U.S. Government Obligations sufficient for such payment.

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

     13. No Recourse Against Others. A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities.

     14. Authentication. This Security shall not be valid until authenticated by the manual signature of an authorized officer of the Trustee or an authenticating agent.

     15. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the Securities and reliance may be placed only on the other identification numbers printed thereon.

     16. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

     17. Governing Law. The Indenture and the Securities shall be governed by and constructed in accordance with, the laws of the State of New York.

     The Company will furnish to any Holder upon written request and without charge a copy of the Indenture. Request may be made to:
