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

Where any person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated, with proper identification of each matter covered therein, and form one instrument.

Section 1.05. Acts of Holders.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution (as provided below in subsection (b) of this Section 1.05) of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 6.01 hereof) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section.

(b) The fact and date of the execution by any person of any such instrument or writing may be proved in any reasonable manner which the Trustee deems sufficient.

thing done, suffered or omitted to be done by the Trustee, any Paying Agent or the Company in reliance thereon, whether or not notation of such action is made upon such Note.

Section 1.06. Notices, etc., to the Trustee and the Company.

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

(a) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed, in writing, to or with the Trustee at the Corporate Trust Office, addressed at The Bank of New York, Global Finance Unit, 000 Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, or at any other address previously furnished in writing to the Holders and the Company by the Trustee; or

Section 1.07. Notice to Holders; Waiver.

Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise expressly provided herein) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at the address of such Holder as it appears in the Note 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 mail notice of any event as required by any provision of this Indenture, then any method of giving such notice as shall be satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice.

If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or excluded, as the case may be.

Additionally, each of the parties hereby waives the right to trial by jury and to assert counterclaims in any such proceedings. Each of the parties hereto hereby agrees that final judgment in any such suit, action or proceeding brought in such court shall be conclusive and binding upon such party and may be enforced in any court of the jurisdiction to which the Company or such Guarantor, as the case may be, is subject by a suit upon such judgment; provided that service of process is effected upon such party in the manner provided by this Indenture.

(b) The Company agrees that service of all writs, process and summonses in any suit, action or proceeding brought in connection with this Indenture or the Notes against the Company in any court of the State of New York or any United States federal court sitting in the Borough of Xxxxxxxxx, Xxx Xxxx Xxxx, Xxx Xxxx, Xxxxxx Xxxxxx, may be made upon CT Corporation System at 000 Xxxxxx Xxxxxx, 00^xx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000, whom the Company irrevocably appoints as its authorized agent for service of process. The Company represents and warrants that CT Corporation System has agreed to act as the agent for service of process for the Company.

any United States federal court in the Borough of Xxxxxxxxx, Xxx Xxxx Xxxx, Xxx Xxxx, Xxxxxx Xxxxxx, service of process upon CT Corporation System, as the authorized agent of the Company for service of process, and written notice of such service to the Company shall be deemed, in every respect, effective service of process upon the Company.

Such waiver will not constitute a waiver of liabilities under the federal securities laws if it is the view of the SEC that such a waiver would be against public policy.

The final Stated Maturity of the Notes shall be June 30, 2010, and the Notes shall bear interest at the rate of % per annum from or from the most recent Interest Payment Date to which interest has been paid, as the case may be, payable semi-annually thereafter in arrears on June 30 and December 30, in each year, commencing on December 30, 2003, to the Holders of record at the close of business on June 15 and December 15, respectively, immediately preceding such Interest Payment Dates, until the principal thereof is paid or duly provided for.

If the Company defaults in a payment of principal on the Notes, the Company shall pay the defaulted principal (plus interest on such defaulted principal to the extent lawful) in any lawful manner. The Company may pay the defaulted principal to the persons who are Holders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trus-

tee and shall promptly mail or cause to be mailed to each Holder a notice that states the special record date, the payment date and the amount of defaulted principal to be paid.

The Company may make payment of any defaulted principal in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after written notice given by the Company to the Trustee of the proposed payment pursuant to this paragraph, such payment shall be deemed practicable by the Trustee.

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

Section 3.02. Registrar and Paying Agent.

The Company shall maintain an office or agency (which shall be located in the Borough of Manhattan in The City of New York, State of New York) where Notes may be presented for registration of transfer or for exchange (the “Registrar”), an office or agency (which shall be located in the Borough of Manhattan in The City of New York, State of New York) where Notes may be presented for payment (the “Paying Agent” or “Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange. The Company may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” or “Agent” includes any additional paying agent. The Company may act as its own Paying Agent, except for the purposes of payments on account of principal on the Notes pursuant to Sections 10.10 and 10.15 hereof.

The Company shall enter into an appropriate agency agreement with any Registrar, co-registrar or Agent not a party to this Indenture, which shall incorporate the provisions of the Trust Indenture Act. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee of the name and address of any such Agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation in accordance with Section 6.07 hereof.

The Company initially appoints the Trustee as the Registrar and Paying Agent and agent for service of notices and demands in connection with the Notes. The office of the Registrar and Paying Agent for purposes of this Section 3.02 shall be 000 Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000.

Section 3.03. Execution and Authentication.

Subject to Section 2.01, the Company shall approve the form of the Notes and any notation, legend or endorsement thereon. Each Note shall be dated the date of issuance and shall show the date of its authentication.

The terms and provisions contained in the Note annexed hereto as Exhibit A shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Company and the Trustee, by

their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby.

The aggregate principal amount of the Global Notes may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for the Depository, as hereinafter provided.

One Officer (who shall have been duly authorized by all requisite corporate actions) shall sign the Notes for the Company by manual or facsimile signature.

If an Officer whose signature is on a Note was an Officer at the time of such execution but no longer holds that office or position at the time the Trustee authenticates the Note, the Note shall nevertheless be valid.

A Note shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture.

The Trustee shall authenticate Notes upon a written order of the Company in the form of an Officers’ Certificate of the Company. Each such written order shall specify the amount of Notes to be authenticated, the date on which the Notes are to be authenticated and whether (subject to this Section 3.03) the Notes are issued as Physical Notes or Global Notes and such other information as the Trustee may reasonably request.

Notwithstanding the foregoing, all Notes issued under this Indenture shall vote and consent together on all matters (as to which any of such Notes may vote or consent) as one class and no series of Notes will have the right to vote or consent as a separate class on any matter.

The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate Notes. Any such appointment to be evidenced by an instrument signed by an authorized officer of the Trustee, a copy of which shall be furnished to the Company. Unless otherwise provided in the appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent, Registrar or agent for service of notices and demands.

The Notes shall be issuable in fully registered form only, without coupons, in denominations of $1,000 and any integral multiple thereof.

Section 3.04. Temporary Notes.

Until definitive Notes are prepared and ready for delivery, the Company may execute and upon a Company Order the Trustee shall authenticate and deliver temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes, in any authorized denominations, but may have variations that the Company reasonably considers appropriate for temporary Notes as conclusively evidenced by the Company’s execution of such temporary Notes.

If temporary Notes are issued, the Company will cause definitive Notes to be prepared without unreasonable delay. After the preparation of definitive Notes, the temporary Notes shall be exchangeable for definitive Notes upon surrender of the temporary Notes at the office or agency of the Company designated for such purpose pursuant to Section 10.02 hereof, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Notes of like tenor and of authorized denominations. Until so exchanged the temporary Notes shall in all respects be entitled to the same benefits under this Indenture as definitive Notes.

Section 3.05. Transfer and Exchange.

The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency designated pursuant to Section 10.02 hereof being sometimes referred to herein as the “Note Register”) in which, subject to such reasonable regulations as the Registrar may prescribe, the Company shall provide for the registration of Notes and of transfers and exchanges of Notes. The Trustee is hereby initially appointed Registrar for the purpose of registering Notes and transfers of Notes as herein provided.

When Notes are presented to the Registrar or a co-Registrar with a request from the Holder of such Notes to register the transfer or exchange for an equal principal amount of Notes of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested; provided, however, that every Note presented or surrendered for registration of transfer or exchange shall be duly endorsed or be accompanied by a written instrument of transfer or exchange in form satisfactory to the Company and the Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. Whenever any Notes are so presented for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes which the Holder making the exchange is entitled to receive. No service charge shall be made to the Noteholder for any registration of transfer or exchange. The Company may require from the Noteholder payment of a sum sufficient to cover all taxes, assessments or other governmental charges that may be imposed in relation to a transfer or exchange, but this provision shall not apply to any exchange pursuant to Section 10.10 or 10.15 or 9.06 hereof (in which events the Company will be responsible for the payment of all such taxes which arise solely as a result of the transfer or exchange and do not depend on the tax status of the Holder). The Trustee shall not be required to exchange or register the transfer of any Note for a period of 15 days before a selection of Notes to be redeemed except, in the case of any Note where public notice has been given that such Note is to be redeemed in part, the portion thereof not to be redeemed or 15 days before an Interest Payment Date.

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

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

Section 3.06. Mutilated, Destroyed, Lost and Stolen Notes.

If a mutilated Note is surrendered to the Registrar or if the Holder of a Note of any series claims that the Note has been lost, destroyed or wrongfully taken, the Company shall execute and upon a Company Order, the Trustee shall authenticate and deliver a replacement Note of like tenor and principal amount, bearing a number not contemporaneously outstanding if (i) the Holder of such Note furnishes to the Company and to the Trustee evidence reasonably acceptable to them of the ownership and the destruction, loss or theft of such Note within a reasonable time after he has notice of such loss, destruction or theft, (ii) an indemnity bond is posted by such Holder, sufficient in the judgment of the Company or the Trustee, as the case may be, to protect the Company, the Trustee or any Agent from any loss that any of them may suffer if such Note is replaced, (iii) makes such request to the Company and the Trustee prior to the Note being acquired by a bona fide purchaser and (iv) satisfies any other reasonable requirements of the Trustee including, if requested, an opinion of counsel for the Holder to the effect that the Holder has complied with the requirements of this Section 3.06. The Company may charge such Holder for the Company’s expenses in replacing such Note (including (i) expenses of the Trustee charged to the Company and (ii) any tax or other governmental charge that may be imposed) and the Trustee may charge the Company for the Trustee’s expenses in replacing such Note. In the event such mutilated, lost, destroyed or stolen Note has become or is about to become due and payable, the Company in its discretion may pay such Note instead of issuing a new Note in replace-

ment thereof.

Every replacement Note issued pursuant to this Section in lieu of any destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Company and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

The provisions of this Section 3.06 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes.

Section 3.07. Payment of Interest; Interest Rights Preserved.

Interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the person in whose name that Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest.

If the Company defaults in a payment of interest on the Notes, the Company shall pay the defaulted interest (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Company may pay the defaulted interest to the persons who are Holders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee and shall promptly mail or cause to be mailed to each Holder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

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

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

Section 3.08. Persons Deemed Owners.

Prior to and at the time of due presentment for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the person in whose name any Note is registered in the Note Register as the owner of such Note for the purpose of receiving payment of principal of, premium, if any, and (subject to Section 3.07 hereof) interest on such Note (and any Additional Amounts thereon) and for all other purposes whatsoever, whether or not such Note shall be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

Section 3.09. Cancellation.

All Notes surrendered for payment, redemption, registration of transfer or exchange shall be delivered to the Trustee and, if not already canceled, shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly canceled by the Trustee. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer or exchange, redemption or payment. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation (subject to the record retention requirements of the Exchange Act). No Notes shall be authenticated in lieu of or in exchange for any Notes canceled as provided in this Section 3.09 hereof, except as expressly permitted by this Indenture. All canceled Notes held by the Trustee shall be disposed of in accordance with the Trustee’s procedures for the disposition of cancelled securities in effect as of the date of such disposition and certification of their disposition delivered to the Company unless by a

Company Order the Company shall timely direct that the canceled Notes be returned to it. The Trustee shall provide the Company a list of all Notes that have been canceled from time to time as requested by the Company.

Section 3.10. Computation of Interest.

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

Section 3.11. Legal Holidays.

In any case where any Interest Payment Date, Redemption Date, date established for the payment of Defaulted Interest or Stated Maturity of any Note shall not be a Business Day, then (notwithstanding any other provision of this Indenture or of the Notes) payment of principal, premium, if any, or interest 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, Redemption Date, date established for the payment of Defaulted Interest or at the Stated Maturity, as the case may be. In such event, no interest shall accrue with respect to such payment for the period from and after such Interest Payment Date, Redemption Date, date established for the payment of Defaulted Interest or Stated Maturity, as the case may be, to the next succeeding Business Day and, with respect to any Interest Payment Date, interest for the period from and after such Interest Payment Date shall accrue with respect to the next succeeding Interest Payment Date.

Section 3.12. CUSIP and CINS Numbers.

The Company in issuing the Notes may use “CUSIP” and “CINS” numbers (if then generally in use), and if so, the Trustee shall use the CUSIP or CINS numbers, as the case may be, in notices of redemption or exchange as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP or CINS number, as the case may be, printed in the notice or on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes and any such redemption shall not be affected by a defect in or omission of such numbers. The Company shall promptly notify the Trustee in writing of any change in the CUSIP or CINS number of any type of Notes.

Section 3.13. Paying Agent To Hold Money in Trust.

Each Paying Agent shall hold in trust for the benefit of the Noteholders or the Trustee all money held by the Paying Agent for the payment of principal of, premium, if any, or interest on the Notes (and any Additional Amounts thereon), and to notify the Trustee of any default by the Company in making any such payment. Money held in trust by the Paying Agent need not be segregated except as required by law and in no event shall the Paying Agent be liable for any interest on any money received by it hereunder. The Company at any time may require the Paying Agent to pay all money held by it to the Trustee and account for any funds disbursed and the Trustee may at any time during the continuance of any Event of Default, upon a Company Order to the Paying Agent, require such Paying Agent to pay forthwith all money so held by it to the Trustee and to account for any funds disbursed. Upon making such payment, the Paying Agent shall have no further liability for the money delivered to the Trustee.

Any money deposited with any Paying Agent, or then held by the Company in trust for the payment of principal or interest on any Note and remaining unclaimed for two years after such principal and interest has become due and payable shall, subject to the requirements of applicable escheat laws, be paid to the Company at its request, or, if then held by the Company in trust, shall be discharged from such trust; and the Holders shall thereafter, as unsecured general creditors, look only to the Company for payment thereof, and all liability of the Paying Agent with respect to such money shall thereupon cease.

Section 3.14. Treasury Notes.

In determining whether the Holders of the required aggregate principal amount of Notes have con-

curred in any direction, waiver, consent or notice, Notes owned by the Company or an Affiliate of the Company shall be considered as though they are not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which a Responsible Officer of the Trustee actually knows are so owned shall be so considered. Upon request of the Trustee, the Company shall notify the Trustee, in writing, when it or any of its Affiliates repurchases or otherwise acquires Notes, of the aggregate principal amount of such Notes so repurchased or otherwise acquired.

Section 3.15. Deposits of Monies.

Prior to 1:00 p.m. New York City time on each Interest Payment Date, maturity date, Change of Control Payment Date and Asset Sale Offer Purchase Date, the Company shall have deposited with the Paying Agent in immediately available funds money sufficient to make cash payments, if any, due on such Interest Payment Date, maturity date, Change of Control Payment Date and Asset Sale Offer Purchase Date, as the case may be, in a timely manner which permits the Paying Agent to remit payment to the Holders on such Interest Payment Date, maturity date, Change of Control Payment Date and Asset Sale Offer Purchase Date, as the case may be.

Section 3.16. Book-Entry Provisions for Global Notes.

(a) The Global Notes initially shall (i) be registered in the name of the Depository or the nominee of such Depository, (ii) be delivered to the Trustee as custodian for such Depository and (iii) bear legends as set forth in Exhibit B.

Members of, or participants in, the Depository (“Agent Members”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depository, or the Trustee as its custodian, or under the Global Note, and the Depository may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Note.

(b) Transfers of Global Notes shall be limited to transfers in whole, but not in part, to the Depository, its successors or their respective nominees. Interests of beneficial owners in the Global Notes may only be transferred or exchanged for Physical Notes in accordance with the rules and procedures of the Depository and the provisions of Section 3.03 hereof. In addition, Physical Notes shall be transferred to all beneficial owners, in exchange for their beneficial interests in Global Notes if (i) the Depository notifies the Company that it is unwilling or unable to continue as Depository for any Global Note, or that it will cease to be a “Clearing Agency” under the Exchange Act, at a time when the Depository is required to be so registered in order to act as Depository, and in either case a successor Depository is not appointed by the Company within 90 days of such notice, (ii) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of Physical Notes or (iii) an Event of Default has occurred and is continuing and the Registrar has received a written request from the Depository to issue Physical Notes.

(c) In connection with any transfer or exchange of a portion of the beneficial interest in any Global Note to beneficial owners pursuant to paragraph (b) of this Section, the Registrar shall (if one or more Physical Notes are to be issued) reflect on its books and records the date and a decrease in the principal amount of the Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be transferred, and the Company shall execute, and the Trustee shall authenticate and deliver, one or more Physical Notes of like tenor and principal amount of authorized denominations.

(d) Any beneficial interest in one of the Global Notes that is transferred to a person who takes delivery in the form of an interest in the other corresponding Global Note will, upon transfer, cease to be an interest in such Note and become an interest in the other corresponding Note and, accordingly, will thereafter be subject to all

transfer restrictions, if any, and other procedures applicable to beneficial interest in such other corresponding Note for as long as it remains such an interest.

(e) In connection with the transfer of Global Notes as an entirety to beneficial owners pursuant to paragraph (b) of this Section, the Global Notes shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depository in exchange for its beneficial interest in the Global Notes, an equal aggregate principal amount at maturity of Physical Notes of authorized denominations.

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

ARTICLE FOUR

Section 4.01. Company’s Option To Effect Defeasance or Covenant Defeasance.

The Company may, at its option by Board Resolution, at any time, with respect to the Notes, elect to have either Section 4.02 or Section 4.03 hereof be applied to all of the Outstanding Notes (the “Defeased Notes”), upon compliance with the conditions set forth below in this Article Four.

Section 4.02. Defeasance and Discharge.

Upon the Company’s exercise under Section 4.01 hereof of the option applicable to this Section 4.02, the Company shall be deemed to have been discharged from its obligations with respect to the Defeased Notes on the date the conditions set forth below are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by the Defeased Notes, which shall thereafter be deemed to be “Outstanding” only for the purposes of Section 4.05 and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Notes and this Indenture insofar as such Notes are concerned (and the Trustee, at the expense of the Company, and, upon Company Request, shall execute proper instruments acknowledging the same), except for the following, which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of Defeased Notes to receive, solely from the trust fund described in Section 4.04 hereof and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and interest on such Notes (and any Additional Amounts thereon) when such payments are due, (b) the Company’s obligations with respect to such Defeased Notes under Sections 3.04, 3.05, 3.06, 10.02 and 10.03 hereof, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder, including, without limitation, the Trustee’s rights under Sections 4.05 and 6.07 hereof, and (d) this Article Four.

Section 4.03. Covenant Defeasance.

Upon the Company’s exercise under Section 4.01 hereof of the option applicable to this Section 4.03, the Company shall be released from its obligations under any covenant or provision contained in Sections 10.05 through 10.21 hereof and the provisions of clause (c) of Section 8.01 shall not apply, with respect to the Defeased Notes, on and after the date the conditions set forth below are satisfied (hereinafter, “covenant defeasance”), and the Defeased Notes shall thereafter be deemed not to be “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to the Defeased Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such Section or Article, whether directly or

indirectly, by reason of any reference elsewhere herein to any such Section or Article or by reason of any reference in any such Section or Article to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 5.01(iii) or (iv) hereof, but, except as specified above, the remainder of this Indenture and such Defeased Notes shall be unaffected thereby.

Section 4.04. Conditions to Defeasance or Covenant Defeasance.

discharge had not occurred;

Opinions required to be delivered under this Section may have such qualifications as are customary for opinions of the type required and reasonably acceptable to the Trustee.

Section 4.05. Deposited Money and U.S. Government Obligations To Be Held in Trust; Other Miscellaneous Provisions.

Subject to the proviso of the last paragraph of Section 10.03, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 4.05, the “Trustee”) pursuant to Section 4.04 in respect of the Defeased Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (other than the Company) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest (and any Additional Amounts), but such money need not be segregated from other funds except to the extent required by law.

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 the Trustee as administrative expenses associated with any such proceeding and, in the event that the Trustee shall consent to the making of such payments directly to Holders, any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the

Trustee under Section 6.07 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 that 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 Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 5.05. Trustee May Enforce Claims Without Possession of Notes.

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

Section 5.06. Application of Money Collected.

Any money collected by the Trustee pursuant to this Article, shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal, premium, if any, or interest (and any Additional Amounts), upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

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

Second: to Holders for interest accrued on the Notes (and any Additional Amounts thereon), ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for interest;

Third: to Holders for principal and premium, if any, amounts owing under the Notes (and any Additional Amounts thereon), ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal and premium, if any; and

Fourth: the balance, if any, to the Company.

The Trustee, upon prior written notice to the Company, may fix a record date and payment date for any payment to Noteholders pursuant to this Section 5.06. At least 15 days before such record date, the Trustee shall, at the Company’s expense, mail to each Holder and the Company a notice that states the record date, the payment date and amount to be paid.

Section 5.07. Limitation on Suits.

No Holder of any Notes shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless

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

(b) the Holders of not less than 25% in principal amount of the Outstanding Notes shall have

made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

(c) such Holder or Holders have offered to the Trustee indemnity or security satisfactory to it against any loss, the costs, expenses and liabilities to be incurred in compliance with such request;

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

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

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

Section 5.08. Unconditional Right of Holders To Receive Principal, Premium and Interest.

Notwithstanding any other provision in this Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to receive cash payment of the principal of, premium, if any, and (subject to Section 3.07 hereof) interest on such Note (and any Additional Amounts thereon) on the respective Stated Maturities expressed in such Note (or, in the case of redemption, on the respective Redemption Date, or, in the case of amortization, on the dates contained in the schedule set forth in Section 3.01) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

Section 5.09. Restoration of Rights and Remedies.

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

Section 5.10. Rights and Remedies Cumulative.

Except as provided in Section 3.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 5.11. Delay or Omission Not Waiver.

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

Section 5.12. Control by Majority.

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

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

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

Section 5.13. Waiver of Past Defaults.

The Holders of not less than a majority in aggregate principal amount of the Outstanding Notes may on behalf of the Holders of all the Notes waive any past Default hereunder and its consequences, except a Default

(a) in the payment of the principal of, or interest on any Outstanding Note or

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

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 Event of Default or impair any right consequent thereon.

Section 5.14. Undertaking for Costs.

All parties to this Indenture agree, and each Holder of any Note by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 5.14 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Notes, or to any suit instituted by any Holder for the enforcement of the payment of the principal of, premium, if any, or interest on any Note on or after the respective Stated Maturities expressed in such Note (or, in the case of redemption, on or after the respective Redemption Dates).

Section 5.15. Waiver of Stay, Extension or Usury Laws.

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

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, 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 provision 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 conform to the requirements of this Indenture.

(b) During the existence of an Event of Default, the Trustee is required to exercise such rights and powers vested in it under this Indenture and use the same degree of care and skill in its exercise thereof as a prudent person would exercise under the circumstances in the conduct of such person’s own affairs.

(c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own grossly negligent action, its own grossly negligent failure to act, or its own willful misconduct, except that no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(d) 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 6.01 and to the provisions of the TIA.

Section 6.02. Notice of Defaults.

Within 45 days after the occurrence of any Default, the Trustee shall transmit by mail to all Holders, as their names and addresses appear in the Note Register, notice of such Default hereunder actually known to a Responsible Officer of the Trustee, unless such Default shall have been cured or waived; provided, however, that, except in the case of a Default in the payment of the principal of, premium, if any, or interest on any Note (and any Additional Amounts thereon) or in the case of any Default arising from the occurrence of a Change of Control, the Trustee shall be protected in withholding such notice if and so long as a trust committee of Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interest of the Holders.

In addition, the Company shall deliver to the Trustee, within 120 days after the end of each fiscal year, a certificate indicating whether the signers thereof know of any Default that occurred during the previous year.

Section 6.03. Certain Rights of Trustee.

Subject to Section 6.01 hereof and the provisions of Section 315 of the Trust Indenture Act:

(a) the Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to

have been signed or presented by the proper party or parties;

(b) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order and any resolution of the Board may be sufficiently evidenced by a Board Resolution thereof;

(c) the Trustee may consult with counsel and any advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon in accordance with such advice or Opinion of Counsel;

(d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred by the Trustee in compliance with such request or direction;

(e) the Trustee shall not be liable for any action taken or omitted by it in good faith and believed by it to be authorized or within the discretion, rights or powers conferred upon it by this Indenture other than any liabilities arising out of its own willful misconduct or negligence;

(f) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, approval, appraisal, bond, debenture, note, coupon, security, other evidence of indebtedness or other paper or document unless requested in writing so to do by the Holders of not less than a majority in aggregate principal amount of the Notes then Outstanding; provided, however, that, if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require indemnity satisfactory to it against such expenses or liabilities as a condition to proceeding; the reasonable expenses of every such investigation shall be paid by the Company or, if paid by the Trustee or any predecessor Trustee, shall be repaid by the Company upon demand; provided, further, the Trustee in its discretion may make such further inquiry or investigation into such facts or matters as it may deem fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney;

(g) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, attorneys, custodians or nominees and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent appointed with due care by it hereunder;

(h) except with respect to Section 10.01, the Trustee shall have no duty to inquire as to the performance of the Company’s covenants in Article Ten. In addition, the Trustee shall not be deemed to have knowledge of any Default or Event of Default except (i) any Event of Default occurring pursuant to Sections 5.01(i) (but excluding defaults in payment of Additional Amounts), 5.01(ii) and 10.01 or (ii) any Default or Event of Default of which a Responsible Officer of the Trustee shall have received written notification or obtained actual knowledge; and

(i) if the Trustee is acting in the capacity of Registrar and/or Paying Agent, then the rights afforded to the Trustee under this Section 6.03 shall also be afforded to it as Registrar and/or Paying Agent.

Section 6.04. Trustee Not Responsible for Recitals, Dispositions of Notes or Application of Proceeds Thereof.

The recitals contained herein and in the Notes, except the Trustee’s certificate of authentication, shall be taken as the statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or the Notes except that the Trus-

tee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Notes and perform its obligations hereunder and that the statements made by it in a Statement of Eligibility and Qualification on Form T-1, if any, to be supplied to the Company are true and accurate subject to the qualifications set forth therein. The Trustee shall not be accountable for the use or application by the Company of Notes or the proceeds thereof.

Section 6.05. Trustee and Agents May Hold Notes; Collections; Etc.

The Trustee, any Paying Agent, Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Notes, with the same rights it would have if it were not the Trustee, Paying Agent, Registrar or such other agent and, subject to Section 6.08 hereof and Sections 310 and 311 of the Trust Indenture Act, may otherwise deal with the Company and receive, collect, hold and retain collections from the Company with the same rights it would have if it were not the Trustee, Paying Agent, Registrar or such other agent.

Section 6.06. Money Held in Trust.

All moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required herein or by law. The Trustee shall not be under any liability for interest on any moneys received by it hereunder.

Section 6.07. Compensation and Indemnification of Trustee and Its Prior Claim.

The Company agrees: (a) to pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation for all services rendered by it hereunder (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); (b) to reimburse the Trustee and each predecessor Trustee upon its request for all reasonable expenses, fees, disbursements and advances incurred or made by or on behalf of it in accordance with any of the provisions of this Indenture (including the reasonable compensation, fees, and the expenses and disbursements of its counsel, accountants and other professionals not regularly in its employ), except any such expense, disbursement or advance as may arise from its gross negligence or bad faith; and (c) to indemnify the Trustee and any of its officers, directors, employees and agents for and to hold it harmless against any loss, liability or expense (including attorneys’ fees and expenses incurred in defending themselves) incurred without gross negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of this Indenture or the trusts hereunder and its duties hereunder, including enforcement of this Section 6.07. The Trustee, Paying Agent and Registrar shall notify the Company of any claim for which they may seek indemnity promptly upon obtaining knowledge thereof; provided, however, that any failure to so notify the Company shall not relieve the Company of its indemnity obligations hereunder except to the extent the Company shall have been adversely affected thereby. The Company shall defend the claim and the indemnified party shall provide reasonable cooperation at the Company’s expense in the defense. Such indemnified parties may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel; provided, however, that the Company shall not be required to pay such fees and expenses if it assumes such indemnified parties’ defense and, in such indemnified parties’ reasonable judgment, there is no conflict of interest between the Company and such parties in connection with such defense. The Company need not pay for any settlement made without its written consent. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by an indemnified party through such party’s own willful misconduct, gross negligence or bad faith. The obligations of the Company under this Section to compensate and indemnify the Trustee and to pay or reimburse the Trustee for expenses, fees, disbursements and advances shall constitute an additional obligation hereunder and shall survive the satisfaction and discharge of this Indenture. To secure the Company’s payment obligations in this Section 6.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held to pay principal and interest on particular Notes (and any Additional Amounts thereon). Such Lien shall survive the satisfaction and discharge of this Indenture. The obligations of the Company under this Section to compensate and indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture or the rejection or termination of this

Indenture under bankruptcy law. Such additional indebtedness shall be a senior claim to that of the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Notes, and the Notes are hereby subordinated to such senior claim. If the Trustee renders services and incurs expenses following an Event of Default under Section 5.01(viii), Section 5.01(ix) or Section 5.01(x) hereof, the parties hereto and the Holders by their acceptance of the Notes hereby agree that such expenses are intended to constitute expenses of administration under any bankruptcy law.

Section 6.08. Conflicting Interests.

The Trustee shall be subject to and comply with the provisions of Section 310(b) of the Trust Indenture Act.

Section 6.09. Corporate Trustee Required; Eligibility.

There shall at all times be a Trustee hereunder which shall be eligible to act as Trustee under Trust Indenture Act Sections 310(a)(1) and (2) and which shall have a combined capital and surplus of at least $100,000,000. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of any Federal, state, territorial or District of Columbia 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. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, the Trustee shall resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 6.10. Resignation and Removal; Appointment of Successor Trustee.

(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, or any trustee or trustees hereinafter appointed, may at any time resign by giving written notice thereof to the Company at least 30 Business Days prior to the date of such proposed resignation. Upon receiving such notice of resignation, the Company shall, after all monies due and owing have been paid to the Trustee, promptly appoint a successor Trustee by written instrument executed by authority of the Board, a copy of which shall be delivered to the resigning Trustee and a copy to the successor Trustee. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 60 Business Days after the giving of such notice of resignation, the resigning trustee may, or any Holder who has been a bona fide Holder of a Note 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. Such court may thereupon, after such notice, if any, as it may deem proper, appoint a successor Trustee.

(c) The Trustee may be removed at any time by an Act of the Holders of a majority in principal amount of the Outstanding Notes, delivered to the Trustee and to the Company.

(d) If at any time:

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

(2) the Trustee shall cease to be eligible under Section 6.09 hereof and shall fail to resign after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Note for at least six months, or

(3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose or rehabilitation, conservation or liquidation,

then, in any case, (i) the Company by a Board Resolution may remove the Trustee, or (ii) subject to Section 5.14, the Holder of any Note who has been a bona fide Holder of a Note 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. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint 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, the Company, by a Board Resolution, shall promptly appoint a successor Trustee. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Notes 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 and supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders of the Notes and accepted appointment in the manner hereinafter provided, the Holder of any Note who has been a bona fide Holder for at least six months may, subject to Section 5.14, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee.

(f) The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee by mailing written notice of such event by first-class mail, postage prepaid, to the Holders of Notes as their names and addresses appear in the Note Register. Each notice shall include the name of the successor Trustee 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 as if originally named as Trustee hereunder; but, nevertheless, on the written request of the Company or the successor Trustee, upon payment of amounts due to it pursuant to Section 6.07, such retiring Trustee shall duly assign, transfer and deliver to the successor Trustee all moneys and property at the time held by it hereunder and shall execute and deliver an instrument transferring to such successor Trustee all the rights, powers, duties and obligations of the retiring Trustee. 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 and powers. Any Trustee ceasing to act shall, nevertheless, retain a prior claim upon all property or funds held or collected by such Trustee to secure any amounts then due it pursuant to the provisions of Section 6.07.

No successor Trustee with respect to the Notes shall accept appointment as provided in this Section 6.11 unless at the time of such acceptance such successor Trustee shall be eligible to act as Trustee under this Article.

Upon acceptance of appointment by any successor Trustee as provided in this Section 6.11, the successor shall give notice thereof to the Holders of the Notes, by mailing such notice to such Holders at their addresses as they shall appear on the Note Register. If the acceptance of appointment is substantially contemporaneous with the resignation, then the notice called for by the preceding sentence may be combined with the notice called for by Section 6.10. If the Company fails to give such notice within 10 days after acceptance of appointment by the successor Trustee, the successor Trustee shall cause such notice to be given at the expense of the Company.

Section 6.12. Merger, Conversion, Amalgamation, Consolidation or Succession to Business.

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

In case at the time such successor to the Trustee under this Section 6.12 shall succeed to the trusts created by this Indenture any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee and deliver such Notes so authenticated; and, in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee under this Section 6.12 may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor Trustee; and in all such cases such certificate shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have been authenticated.

However, any such Holder, or subsequent Holder, may revoke the consent as to his Note or portion of a Note if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective. An amendment or waiver shall become effective in accordance with its terms and thereafter bind every Holder.

The Company shall keep proper books of record and account, in which full and correct entries will be made of all financial transactions and the assets and business of the Company and each Restricted Subsidiary of the Company in material compliance with GAAP.

Any payments made under or with respect to the Notes will be made free and clear of, and without withholding or deduction for or on account of, any present or future tax, duty, levy, impost, assessment or other governmental charge imposed or levied by or on behalf of Mexico or of any subdivision thereof or the jurisdiction of incorporation of any successor to the Company (each, a “Successor Jurisdiction”) or by any authority or agency therein or thereof having power to tax (hereinafter “Taxes”), unless the Company is required to withhold or deduct Taxes by law or by the interpretation or administration thereof. If the Company is so required to withhold or deduct any amount for or on account of Taxes from any payment made under or with respect to the Notes, the Company will (i) pay such additional amounts, subject to the exceptions listed below, (“Additional Amounts”) as may be necessary, so that the net amount received by each Holder of Notes (including Additional Amounts) after such withholding or deduction will not be less than the amount such Holder would have received if such Taxes had not been withheld or deducted, (ii) deduct or withhold such Taxes and (iii) remit the full amount so deducted or withheld to the relevant taxing or other authority.

Notwithstanding the foregoing, no such Additional Amounts shall be payable with respect to:

(a) any Taxes which are imposed on, or deducted or withheld from, payments made to the Holder or beneficial owner of a Note by reason of the existence of any present or former connection between the Holder or beneficial owner of the Note (or between a fiduciary, settlor, beneficiary, member of, or possessor of a power over, such Holder or beneficial owner, if such Holder or beneficial owner is an estate, trust or partnership) and Mexico (or any political subdivision or territory or possession thereof or area subject to its jurisdiction) or any Successor Jurisdiction (including, without limitation, such Holder or beneficial owner (or such fiduciary, settlor, beneficiary, member, shareholder or possessor) (i) being or having been a citizen or resident thereof, (ii) maintaining or having maintained an office, permanent establishment, fixed base or branch therein, or (iii) being or having been present, or engaged in trade or business therein), except for a connection arising from the mere ownership of, or mere receipt of payment under, such Note or the mere exercise of rights under such Note or the Indenture (personally

or through the Trustee);

(b) any estate, inheritance, gift, sales, stamp, transfer, personal property or similar Tax, assessment or governmental charge;

(c) any Taxes that are imposed on, or withheld or deducted from, payments made to the Holder or beneficial owner of a Note to the extent such Taxes would not have been so imposed, deducted or withheld but for the failure by such Holder or beneficial owner of such Note to timely comply with any certification, identification, information, documentation, declaration or other reporting requirement if (i) such compliance is required or imposed by a statute, treaty, regulation, ruling or administrative practice as a precondition to exemption from, or reduction in the rate of, the imposition, withholding or deduction of any Taxes, and (ii) at least 60 days prior to (A) the first payment date with respect to which the Company shall apply this clause (c) and (B) in the event of a change in such certification, identification, documentation, declaration or other reporting requirement, the first payment date subsequent to such change, the Company shall have notified the Trustee in writing, that such Holders or beneficial owners of the Notes will be required to provide such information or documentation;

(d) any Taxes that are imposed or levied by reason of the failure by the Holder or beneficial owner of such Note to timely comply (subject to the conditions set forth below) with a written request by or on behalf of the Company to provide information or other evidence concerning the nationality or registration with the Secretaría de Hacienda y Crédito Público (Ministry of Finance and Public Credit) of the Holder of such Note that is necessary to determine the appropriate rate of deduction or withholding of Taxes applicable to such Holder; provided that at least 60 days prior to the first payment date with respect to which the Company shall apply this clause (d), the Company shall have notified the Trustee in writing that such Holders of Notes will be required to provide such information, documentation or other evidence.

(e) to or on behalf of a Holder or beneficial owner of a Note in respect of Taxes that would not have been imposed but for the presentation by such Holder or beneficial owner for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for and notice thereof given to Holders, whichever occurs later, except to the extent that the Holder or beneficial owner of such Note would have been entitled to Additional Amounts in respect of such Taxes on presenting such Note for payment on any date during such 30-day period;

(f) any Taxes that are payable other than by deduction or withholding from payments of principal of, (or premium, if any, on) or interest on, the Notes;

(g) any tax, duty, assessment or other governmental charge imposed on a Holder that is a partnership or a fiduciary or any person other than the sole beneficial owner of such payment, but only to the extent that any beneficial owner or member of the partnership or beneficiary or settlor with respect to the fiduciary would not have been entitled to the payment of Additional Amounts had the beneficial owner, member, beneficiary or settlor directly been the holder of such Note; or

(h) any combination of (a), (b), (c), (d), (e), (f) or (g) above (the Taxes described in clauses (a) through (g) for which no Additional Amounts are payable, are hereinafter referred to as “Excluded Taxes”).

Notwithstanding the foregoing, the limitations on the Company’s obligation to pay Additional Amounts set forth in clause (c) and (d) above shall not apply if (i) the provision of information, documentation or other evidence described in such clause (c) or (d) would be materially more onerous, in procedure or in the substance of information disclosed, to a Holder or beneficial owner of a Note (taking into account any relevant differences between US and Mexican law (or the law of any applicable Successor Jurisdiction), regulation or administrative practice) than comparable information or other reporting requirements imposed under US tax law (including the United States—Mexico Income Tax Treaty), regulation and administrative practice (such as IRS Forms 1001, W-8 and W-9) and such Holder or beneficial owner shall have so certified to the Company or (ii) Rule 3.25.15 issued by the Ministry of Finance and Public Credit on May 30, 2002 or a substantially similar successor of such rule is in effect, unless

(a) the provision of the information, documentation or other evidence described in clause (c) or (d) is expressly required by statute, regulation, ruling or administrative practice in order to apply Rule 3.25.15 (or a substantially similar successor of such rule), the Company cannot obtain such information, documentation or other evidence on its own through reasonable diligence and the Company otherwise would meet the requirements for application of Rule 3.25.15 (or such successor of such rule) or (b) in the case of a holder or beneficial owner of a Note that is a pension fund or other tax-exempt organization, payments to such holder or beneficial owner would be subject to Taxes at a rate less than that provided by Rule 3.25.15 if the information, documentation or other evidence required under clause (c) or (d) above were provided. In addition, clause (c) and (d) above shall not be construed to require that a non-Mexican pension or retirement fund or other holder or beneficial owner of a Note register with the Ministry of Finance and Public Credit of Mexico for the purpose of establishing eligibility for an exemption from or reduction of Taxes.

The Company will, upon written request, provide the Trustee and the Holders with a duly certified or authenticated copy of an original receipt of the payment of Taxes which the Company has withheld or deducted in respect of any payments made under or with respect to the Notes.

In the event that Additional Amounts actually paid with respect to any Notes are based on Taxes in excess of the appropriate Taxes applicable to the holder or beneficial owner of such Notes and, as a result thereof, such holder or beneficial owner is entitled to make a claim for a refund of such excess, or credit such excess against any tax imposed by Mexico or any applicable Successor Jurisdiction (or any tax of any political subdivision thereof), then, to the extent it is able to do so without jeopardizing its entitlement to such refund or credit, such holder or beneficial owner shall, by accepting Notes, be deemed to have assigned and transferred all right, title and interest to any claim for a refund or credit of such excess to the Company. By making such assignment or transfer, the holder or beneficial owner makes no representation or warranty that the Company will be entitled to receive such refund or credit and incurs no other obligation with respect thereto (including executing or delivering any documents and paying any costs or expenses of the Company relating to obtaining such refund or credit). Nothing contained in this paragraph shall interfere with the right of each holder or beneficial owner of Notes to arrange its tax affairs in whatever manner it deems appropriate nor oblige any holder or beneficial owner to claim any refund or credit or to disclose any information relating to its tax affairs or any computation in respect thereof or to do anything that would prejudice its ability to benefit from any other credits, reliefs, remissions or repayments to which it may be entitled.

At least 30 days prior to each date on which any payment under or with respect to the Notes is due and payable, if the Company will be obligated to pay Additional Amounts with respect to such payment (other than Additional Amounts payable on the basis of the facts and laws existing on the date of the Prospectus), the Company will deliver to the relevant Trustee a certificate signed by a duly authorized officer stating the fact that such Additional Amounts will be payable and the amounts so payable and will set forth such other information necessary to enable the relevant Trustee to pay such Additional Amounts to Holders on the payment date. Whenever in this Indenture there is mentioned, in any context, the payment of principal (and premium, if any), Redemption Price, interest or any other amount payable under or with respect to any Note, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

In addition, the Company will pay any stamp, issue, registration, documentary or other similar taxes and other duties (including interest and penalties) (i) payable in Mexico (or any political subdivision thereof) in respect of the creation, issue and offering of the Notes, and (ii) payable in Mexico or any Successor Jurisdiction (or any political subdivision thereof) in respect of the subsequent redemption or retirement of the Notes (other than, in the case of any subsequent redemption or retirement, Excluded Taxes).

Section 10.10. Change of Control.

Upon the occurrence of a Change of Control (the date of such occurrence being the “Change of Control Date”), each Holder shall have the right to require that the Company make an offer to purchase (the “Change of Control Offer”), on a business day (the “Change of Control Payment Date”) not later than 90 days following the

Change of Control Date, such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof on any Change of Control Payment Date, plus accrued and unpaid interest, if any, to any Change of Control Payment Date. Notice of a Change of Control Offer shall be given to Holders and the Trustee not less than 30 days nor more than 60 days before the Change of Control Payment Date. The Change of Control Offer is required to remain open for at least 20 business days and until the close of business on the Change of Control Payment Date.

Notice of a Change of Control Offer shall be mailed by the Company (or upon the Company’s request, at the Company’s expense, shall be mailed by the Trustee), not more than 30 Days after the Change of Control Date to the Holders of Notes at their last registered addresses with a copy to the Trustee and the Paying Agent. The Change of Control Offer shall remain open from the time of mailing for at least 20 Business Days and until 5:00 p.m., New York City time, on the Change of Control Payment Date. The notice, which shall govern the terms of the Change of Control Offer, shall include such disclosures as are required by law and shall state:

(a) that the Change of Control Offer is being made pursuant to this Section 10.10 and that all Notes tendered into the Change of Control Offer will be accepted for payment;

(b) the purchase price (including the amount of accrued interest, if any) for each Note, the Change of Control Payment Date and the date on which the Change of Control Offer expires;

(d) that, unless the Company shall default in the payment of the purchase price, any Note accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest after the Change of Control Payment Date;

(e) that Holders electing to have Notes purchased pursuant to a Change of Control Offer will be required to surrender their Notes to the Paying Agent at the address specified in the notice prior to 5:00 p.m., New York City time, on the Change of Control Payment Date and must complete any form letter of transmittal proposed by the Company and acceptable to the Trustee and the Paying Agent;

(f) that Holders of Notes will be entitled to withdraw their election if the Paying Agent receives, not later than 5:00 p.m., New York City time, on the Change of Control Payment Date, a facsimile transmission or letter setting forth the name of the Holders, the principal amount of Notes the Holders delivered for purchase, the Note certificate number (if any) and a statement that such Holder is withdrawing his election to have such Notes purchased;

(g) that Holders whose Notes are purchased only in part will be issued Notes of like tenor equal in principal amount to the unpurchased portion of the Notes surrendered;

(h) the instructions that Holders must follow in order to tender their Notes; and

(i) information concerning the business of the Company, the most recent annual and quarterly reports of the Company filed with the SEC pursuant to the Exchange Act (or, if the Company is not required to file any such reports with the SEC, the comparable reports prepared pursuant to Section 7.04(a)) and such other information concerning the circumstances and relevant facts regarding such Change of Control and Change of Control Offer as would, in the good faith judgment of the Company, be material to a Holder of Notes in connection with the decision of such Holder as to whether or not it should tender Notes pursuant to the Change of Control Offer.

On the Change of Control Payment Date, the Company will (i) accept for payment Notes or portions thereof tendered pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent money, in immediately available funds, sufficient to pay the purchase price of all Notes or portions thereof so tendered and accepted and (iii) deliver to the Trustee the Notes so accepted together with an Officers’ Certificate setting forth the Notes or

portions thereof tendered to and accepted for payment by the Company. The Paying Agent will promptly mail or deliver to the Holders of Notes so accepted payment in an amount equal to the purchase price, and the Trustee shall promptly authenticate and mail or deliver to such Holders a new Note of like tenor equal in principal amount to any unpurchased portion of the Note surrendered. Any Notes not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Change of Control Offer not later than the first Business Day following the Change of Control Payment Date.

Except as described above with respect to a Change of Control, this Indenture does not contain provisions that permit the Holders to require that the Company repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction which may be highly leveraged. If a Change of Control Offer is made, there can be no assurance that the Company will have available funds sufficient to pay for all of the Notes that might be delivered by holders of Notes seeking to accept the Change of Control Offer.

The Company shall not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

If the Company is required to make a Change of Control Offer, the Company will comply with all applicable tender offer laws and regulations, including, to the extent applicable, Section 14(e) and Rule 14e-1 under the Exchange Act, and any other applicable U.S. or Mexican securities laws and regulations. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 10.10, the Company will comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 10.10 by virtue thereof.

Section 10.11. Limitation on Indebtedness.

(a) The Company shall not, and shall not permit any Restricted Subsidiary to, Incur, directly or indirectly, any Indebtedness; provided, however, that the Company may Incur Indebtedness if, on the date of such Incurrence and after giving effect thereto, the Consolidated Leverage Ratio would be less than or equal to 4.0 to 1.0.

(b) Notwithstanding the foregoing paragraph (a), the Company or the Restricted Subsidiaries (to the extent specified and so long as each Restricted Subsidiary is in compliance with Section 10.18), may Incur any or all of the following Indebtedness:

(i) Indebtedness of the Company having an aggregate principal amount not to exceed $50 million at any time outstanding;

(ii) Indebtedness owed to and held by the Company or a Restricted Subsidiary; provided, however, that (i) any event which results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any subsequent transfer of such Indebtedness (other than to the Company or a Restricted Subsidiary) shall be deemed, in each case, to constitute the Incurrence of such Indebtedness by the obligor thereon and (ii) if the Company is the obligor on such Indebtedness, such Indebtedness is expressly subordinated to the prior payment in full in cash of all obligations with respect to the Notes;

(iii) the Notes and the Existing Notes;

(B) 50% of the aggregate Net Cash Proceeds received by the Company from the issuance or sale of its Capital Stock (other than Disqualified Stock) and the aggregate cash received by the Company as a capital contribution from its stockholders, in each case subsequent to May 17, 1999 (other than an (i) issuance or sale to a Subsidiary of the Company, and (ii) to the extent such Net Cash Proceeds or cash received are used to Incur new Indebtedness pursuant to clause (vi) of paragraph (b) of Section 10.11); plus

(C) the amount by which Indebtedness of the Company is reduced on the Company’s balance sheet upon the conversion or exchange (other than by a Subsidiary of the Company) subsequent to May 17, 1999 of any Indebtedness of the Company convertible or exchangeable for Capital Stock (other than Disqualified Stock) of the Company (less the amount of any cash, or the fair value of any other property, distributed by the Company upon such conversion or exchange); plus

(D) to the extent not included in Consolidated Net Income, an amount equal to the net reduction (received by the Company or any Restricted Subsidiary in cash or Temporary Cash Investments) in Investments (other than Permitted Investments) since May 17, 1999 (including reductions resulting from return of equity capital, repayments of the principal of loans or advances or the redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary or other disposition of Investments), not to exceed, in the case of any Investment, the amount of Investments (other than Permitted Investments) made by the Company and its Restricted Subsidiaries in such Person since May 17, 1999.

(b) The provisions of the foregoing paragraph (a) shall not prohibit:

(i) so long as no Default shall have occurred and be continuing, any Restricted Payment made out of the proceeds of the substantially concurrent sale of, or capital contribution in respect of, or made by exchange for, Capital Stock of the Company (other than Disqualified Stock and other than Capital Stock issued or sold to a Subsidiary of the Company or an employee stock ownership plan or to a trust established by the Company or any of its Subsidiaries for the benefit of their employees); provided, however, that (A) the proceeds of any such substantially concurrent sale of, or capital contribution in respect of, Capital Stock are not used to Incur new Indebtedness pursuant to clause (b)(vi) of Section 10.11, (B) such Restricted Payment shall be excluded in the calculation of the amount of Restricted Payments made since May 17, 1999 and (C) the Net Cash Proceeds from such sale shall be excluded from the calculation of amounts under clause (3) (B) of paragraph (a) above;

In no event shall a Restricted Payment made on the basis of consolidated financial statements prepared in good faith in accordance with GAAP be subject to rescission or constitute a Default by reason of any requisite subsequent restatement of such financial statements which would have made such Restricted Payment prohibited at the time that it was made.

Section 10.14. Limitation on Affiliate Transactions.

(a) The Company shall not, and shall not permit any Restricted Subsidiary to, enter into or permit to exist any transaction (including the purchase, sale, lease or exchange of any property, employee compensation arrangements or the rendering of any service) with any Affiliate of the Company (an “Affiliate Transaction”) unless the terms thereof, taken as a whole, (1) are no less favorable to the Company or such Restricted Subsidiary than those that could be obtained at the time of such transaction in arm’s-length dealings with a Person who is not such an Affiliate, (2) if such Affiliate Transaction involves an amount in excess of $1.0 million, are set forth in writing in an officers certificate delivered to the Trustee, (3) if such Affiliate Transaction involves an amount in excess of $5.0 million, have been approved by a majority of the members of the Board of Directors having no personal stake in such Affiliate Transaction and who are not employees or officers of, or appointed by, the Affiliate in question and (4) if such Affiliate Transaction involves an amount in excess of $25.0 million, have been determined by a U.S. investment banking firm nationally recognized in the United States or by a nationally recognized expert in the U.S. telecommunications industry with experience in evaluating similar transactions to be fair, from a financial standpoint, to the Company and its Restricted Subsidiaries.

Section 10.15. Limitation on Sales of Assets and Subsidiary Stock

(a) The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Disposition unless (i) the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Disposition at least equal to the Fair Market Value (including as to the value of all non-cash consideration), as determined in good faith by the Board of Directors, of the shares and assets subject to such Asset Disposition and (ii) at least 75% of the consideration thereof received by the Company or such Restricted Subsidiary, as the case may be, is in the form of cash or cash equivalents. In the event and to the extent that the Net Available Cash received by the Company and its Restricted Subsidiaries from one or more Asset Dispositions occurring on or after May 17, 1999 in any period of 12 consecutive months exceeds 10% of Adjusted Consolidated Net Tangible Assets (determined as of the date closest to the commencement of such 12-month period for which a consolidated balance sheet has been filed with the Commission or provided to the Trustee pursuant to Section 7.04(a)), then the Company shall or shall cause the relevant Restricted Subsidiary to:

(A) first, to the extent the Company elects (or is required by the terms of any Indebtedness), to prepay, repay, redeem or purchase Senior Indebtedness of the Company or Indebtedness (other than any Disqualified Stock) of a Restricted Subsidiary (in each case other than Indebtedness owed to the Company or an Affiliate of the Company) within 360 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash;

(B) second, to the extent of the balance of such Net Available Cash after application, if any, in accordance with clause (A), to the extent the Company elects, to acquire Additional Assets within 360 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; and

(C) third, to the extent of the balance of such Net Available Cash after application, if any, in accordance with clauses (A) and (B) (the “Offer Excess Proceeds”), and subject to paragraph (b) below, to make an offer to the holders of the Notes (and to holders of other Senior Indebtedness designated by the Company) to purchase Notes (and such other Senior Indebtedness) pursuant to and subject to the conditions set forth in paragraph (b) below;

provided, however, that in connection with any prepayment, repayment or purchase of Indebtedness pursuant to clause (A) or (C) above, the Company or such Restricted Subsidiary shall permanently retire such Indebtedness and shall cause the related loan commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid or purchased. Notwithstanding the foregoing provisions of this paragraph, the Company and the Restricted Subsidiaries shall be entitled, but shall not be required, to apply any Net Available Cash in accor-

dance with this paragraph except to the extent that the aggregate Net Available Cash from all Asset Dispositions which are not applied in accordance with this paragraph exceeds US$10 million. Pending application of Net Available Cash pursuant to this covenant, such Net Available Cash shall be invested in Permitted Investments.

For the purposes of this covenant, the following are deemed to be cash or cash equivalents: (x) the assumption of Indebtedness (other than Subordinated Obligations) of the Company or any Restricted Subsidiary and the release of the Company or such Restricted Subsidiary from all liability on such Indebtedness in connection with such Asset Disposition and (y) securities received by the Company or any Restricted Subsidiary from the transferee that are promptly converted by the Company or such Restricted Subsidiary into cash.

(b) In the event of an Asset Disposition that requires an offer to purchase the Notes (and other Senior Indebtedness) pursuant to clause (a)(C) above, the Company will be required to purchase (an “Asset Sale Offer”), from all Holders issued under this Indenture, that aggregate principal amount of Notes as can be purchased by application of such Offer Excess Proceeds at a price in cash equal to 100% of the principal amount thereof plus, in each case, accrued and unpaid interest, if any, to the purchase date. Each Asset Sale Offer shall remain open for a period of 20 business days or such longer period as may be required by law. To the extent that the aggregate purchase price for the applicable issue of Notes tendered pursuant to an Asset Sale Offer is less than the Offer Excess Proceeds, the Company or any Restricted Subsidiary may use such deficiency for general corporate purposes. If the aggregate purchase price for the Notes validly tendered and not withdrawn by holders thereof exceeds the amount of Notes which can be purchased with the Offer Excess Proceeds, Notes to be purchased will be selected on a pro rata basis. Upon completion of such Asset Sale Offer, the amount of Offer Excess Proceeds shall be reset to zero.

Notice of an Asset Sale Offer shall be mailed by the Company (or upon the Company’s request, at the Company’s expense, shall be mailed by the Trustee), not more than 20 Business Days after the obligation to make such Asset Sale Offer arises to the Holders of Notes at their last registered addresses with a copy to the Trustee and the Paying Agent. The Asset Sale Offer shall remain open from the time of mailing for at least 20 Business Days and until 5:00 p.m., New York City time, on the date fixed for Purchase of Notes validly tendered and not withdrawn, which date shall be not later than the 30th Business Day following the mailing of such Asset Sale Offer (the “Asset Sale Offer Purchase Date”). The notice, which shall govern the terms of the Asset Sale Offer, shall include such disclosures as are required by law and shall state:

(i) that the Asset Sale Offer is being made pursuant to this Section 10.15 and that the Asset Sale Offer shall remain open for a period of 20 Business Days or such longer period as may be required by law;

(ii) the purchase price (including the amount of accrued interest, if any) for each Note, the Asset Sale Offer Purchase Date and the date on which the Asset Sale Offer expires;

(iii) that any Note not tendered for payment will continue to accrue interest in accordance with the terms thereof;

(iv) that, unless the Company shall default in the payment of the purchase price, any Note accepted for payment pursuant to the Asset Sale Offer shall cease to accrue interest after the Asset Sale Offer Purchase Date;

(v) that Holders electing to have Notes purchased pursuant to an Asset Sale Offer will be required to surrender their Notes to the Paying Agent at the address specified in the notice prior to 5:00 p.m., New York City time, on the Asset Sale Offer Purchase Date and must complete any form letter of transmittal proposed by the Company and acceptable to the Trustee and the Paying Agent;

(vi) that Holders of Notes will be entitled to withdraw their election if the Paying Agent receives, not later than 5:00 p.m., New York City time, on the Asset Sale Offer Purchase Date, a facsimile transmission or letter setting forth the name of the Holders, the principal amount of Notes the Holders delivered for purchase, the Note certificate number (if any) and a statement that such Holder is withdrawing his election to have such Notes pur-

chased;

(vii) that Holders whose Notes are purchased only in part will be issued Notes of like tenor equal in principal amount to the unpurchased portion of the Notes surrendered;

(viii) the instructions that Holders must follow in order to tender their Notes; and

(ix) information concerning the business of the Company, the most recent annual and quarterly reports of the Company filed with the SEC pursuant to the Exchange Act (or, if the Company is not required to file any such reports with the SEC, the comparable reports prepared pursuant to Section 7.04(a)) and such other information concerning the circumstances and relevant facts regarding such Asset Sale and Asset Sale Offer as would, in the good faith judgment of the Company, be material to a Holder of Notes in connection with the decision of such Holder as to whether or not it should tender Notes pursuant to the Asset Sale Offer.

On the Asset Sale Offer Purchase Date, the Company will (i) accept for payment Notes or portions thereof tendered pursuant to the Asset Sale Offer, (ii) deposit with the Paying Agent money, in immediately available funds, sufficient to pay the purchase price of all Notes or portions thereof so tendered and accepted and (iii) deliver to the Trustee the Notes so accepted together with an Officers’ Certificate setting forth the Notes or portions thereof tendered to and accepted for payment by the Company. The Paying Agent will promptly mail or deliver to the Holders of Notes so accepted payment in an amount equal to the purchase price, and the Trustee shall promptly authenticate and mail or deliver to such Holders a new Note of like tenor equal in principal amount to any unpurchased portion of the Note surrendered. Any Notes not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Asset Sale Offer not later than the first Business Day following the Asset Sale Offer Purchase Date.

Section 10.16. Limitation on Liens.

The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, Incur or permit to exist any Lien of any nature whatsoever on any of its properties (including Capital Stock of a Restricted Subsidiary), whether owned at the Issue Date or thereafter acquired, other than Permitted Liens, without effectively providing that the Notes shall be secured equally and ratably with (in the case of Senior Indebtedness) or prior to (in the case of Subordinated Obligations) the obligations so secured for so long as such obligations are so secured.

Section 10.17. Limitation on Lines of Business.

such Restricted Subsidiary under its Subsidiary Guarantee; provided that this clause shall not be applicable to any Guarantee of any Restricted Subsidiary that existed at the time such Person became a Restricted Subsidiary and was not incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary.

Section 10.19. Limitation on the Sales or Issuance of Capital Stock of Restricted Subsidiaries.

The Company shall not sell or otherwise dispose of any Capital Stock of a Restricted Subsidiary, and shall not permit any Restricted Subsidiary, directly or indirectly, to issue or sell or otherwise dispose of any of its Capital Stock except (i) to the Company or a Restricted Subsidiary, (ii) if, immediately after giving effect to such issuance, sale or other disposition, neither the Company nor any of its Subsidiaries owns any Capital Stock of such Restricted Subsidiary, (iii) if required, the issuance, transfer, conveyance, sale or other disposition of directors’ qualifying shares, (iv) in a transaction in which, or in connection with which, the Company or a Restricted Subsidiary acquires at the same time sufficient Capital Stock of such Restricted Subsidiary to at least maintain the same percentage ownership interest it had prior to such transaction, (v) Disqualified Stock of a Restricted Subsidiary Incurred to Refinance Disqualified Stock of such Restricted Subsidiary; provided, however, that the amounts of the redemption obligations of such Disqualified Stock shall not exceed the amounts of the redemption obligations of, and such Disqualified Stock shall have redemption obligations no earlier than those required by, the Disqualified Stock being Refinanced or (vi) if, immediately after giving effect to such issuance, sale or other disposition, such Restricted Subsidiary would no longer constitute a Restricted Subsidiary and any Investment in such Person remaining after giving effect thereto would have been permitted to be made under Section 10.13 if made on the date of such issuance, sale or other disposition.

Section 10.20. Limitation on Restrictions on Distributions from Restricted Subsidiaries.

The Company shall not, and shall not permit any Restricted Subsidiary to, create or otherwise cause or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to (a) pay dividends or make any other distributions on its Capital Stock to the Company or a Restricted Subsidiary or pay any Indebtedness owed to the Company, (b) make any loans or advances to the Company or (c) transfer any of its property or assets to the Company, except:

(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; provided, that such Opinion of Counsel may rely, as to matters of fact, upon an Officers’ Certificate.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Sections 4.05 and 6.07 and, if money shall have been deposited with the Trustee pursuant to subclause (1)(b) of this Section 11.01, the obligations of the Trustee under Section 11.02 and the last paragraph of Section 10.03 shall survive.

Section 11.02. Application of Trust Money.

Subject to the provisions of the last paragraph of Section 10.03, all money deposited with the Trustee pursuant to Section 11.01 shall be held in trust and applied by it, in accordance with the provisions of the Notes 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 of, premium, if any,

and interest on the Notes (and any Additional Amounts thereon) for whose payment such money has been deposited with the Trustee.

ARTICLE TWELVE

REDEMPTION

Section 12.01. Notices to the Trustee.

If the Company elects to redeem Notes pursuant to Section 12.07, it shall notify the Trustee of the Redemption Date and principal amount of Notes to be redeemed.

The Company shall notify the Trustee of any redemption at least 30 days before the Redemption Date by an Officers’ Certificate, stating that such redemption will comply with the provisions hereof and of the Notes.

Section 12.02. Selection of Notes To Be Redeemed.

In the event that less than all of the Notes are to be redeemed at any time, selection of such Notes for redemption will be made by the Trustee in compliance with any applicable requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not then listed on a national securities exchange (or if the Notes are so listed but the exchange does not impose requirements with respect to the selection of debt securities for redemption), on a pro rata basis, by lot or by such method as the Trustee in its sole discretion shall deem fair and appropriate; provided, however, that no Notes of a principal amount of $1,000 or less shall be redeemed in part.

The Trustee shall promptly notify the Company and the Registrar in writing of the Notes selected for redemption and, in the case of any Notes selected for partial redemption, the principal amount thereof to be redeemed.

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

Section 12.03. Notice of Redemption.

Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Notes to be redeemed, at the address of such Holder appearing in the Note register maintained by the Registrar.

All notices of redemption shall identify the Notes to be redeemed and shall state:

(a) the Redemption Date;

(b) the Redemption Price and the amount of accrued interest, if any, to be paid;

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

(d) if any Note is to be redeemed in part, the portion of the principal amount (equal to $1,000 or

any integral multiple thereof) of such Note to be redeemed and that on and after the Redemption Date, upon surrender for cancellation of such Note to the Paying Agent, a new Note or Notes in the aggregate principal amount equal to the unredeemed portion thereof will be issued without charge to the Noteholder;

(e) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price and the name and address of the Paying Agent; and

(f) the CUSIP or CINS number, if any, relating to such Notes.

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

Section 12.04. Effect of Notice of Redemption.

Once notice of redemption is mailed, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price. Upon surrender to the Paying Agent, such Notes called for redemption shall be paid at the Redemption Price plus accrued interest, if any, to the Redemption Date, but interest installments whose maturity is on or prior to such Redemption Date will be payable on the relevant Interest Payment Dates to the Holders of record at the close of business on the relevant record dates referred to in the Notes.

Section 12.05. Deposit of Redemption Price.

On or prior to any Redemption Date, the Company shall deposit with the Paying Agent an amount of money in same day funds sufficient to pay the Redemption Price of, and any accrued interest on (and any Additional Amounts), all the Notes or portions thereof which are to be redeemed on that date, other than Notes or portions thereof called for redemption on that date which have been delivered by the Company to the Trustee for cancellation.

If the Company complies with the preceding paragraph, then, unless the Company defaults in the payment of such Redemption Price, interest on the Notes to be redeemed will cease to accrue on and after the applicable Redemption Date, whether or not such Notes are presented for payment, and the Holders of such Notes shall have no further rights with respect to such Notes except for the right to receive the Redemption Price plus unpaid interest on the Notes through the Redemption Date, upon surrender of such Notes. If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the principal, premium, if any, and, to the extent lawful, accrued interest thereon shall, until paid, bear interest from the Redemption Date at the rate provided in the Notes.

Section 12.06. Notes Redeemed or Purchased in Part.

Upon surrender to the Paying Agent of a Note which is to be redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the unredeemed portion of the principal of the Note so surrendered that is not redeemed.

Section 12.07. Optional Redemption.

(a) The Notes are redeemable, at the Company’s option, in whole or in part, at any time or from time to time, upon not less than 30 nor more than 60 days’ prior notice mailed by first-class mail to each Holder’s registered address, at a redemption price equal to 101% of the principal Notes being redeemed plus accrued and unpaid intrest to the date of redemption.

(b) [Reserved].

under) of Mexico or any political subdivision or taxing authority thereof or therein affecting taxation or any amendment to or change in an official interpretation, administration or application of such laws, regulations or rulings (including a holding by a court of competent jurisdiction), which amendment or change of such laws, regulations or rulings becomes effective on or after the date on which the Notes are originally issued, the Company would be or would become obligated, after taking reasonable measures available to it to avoid such requirement, to pay Additional Amounts in respect of any Note pursuant to the terms and conditions thereof in excess of the Additional Amounts that the Company would be obligated to pay if payments made on the Notes were subject to withholding or deduction of Mexican Taxes at a rate of 4.9 percent (“Excessive Additional Amounts”), then, at the Company’s option, the Notes may be redeemed in whole, but not in part, at any time, on giving not less than 30 nor more than 60 days’ notice mailed to the Trustee at a cash price equal to the sum of (i) 100% of the principal amount thereof on the date of redemption, (ii) the accrued and unpaid interest, if any, thereon to the date of redemption, and (iii) any Additional Amounts which would otherwise be payable (the “Redemption Price”); provided, however, that (1) no such notice of redemption may be given earlier than 90 days prior to the earliest date on which, but for such redemption, the Company would be obligated to pay such Excessive Additional Amounts were a payment on the Notes then be due and (2) at the time such notice of redemption is given, such obligation to pay such Additional Amounts (including any Excessive Additional Amounts) remains in effect.

Prior to publication of any notice of redemption pursuant to this paragraph (c), the Company shall deliver to the Trustee (i) a certificate signed by a duly authorized officer of the Company stating that the Company is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent of the right of the Company to so redeem have occurred and (ii) an opinion of independent Mexican legal counsel or independent public accountants selected by the Company and reasonably acceptable to the Trustee to the effect that the Company has or will become obligated to pay such Excessive Additional Amounts as a result of such change or amendment.

IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed as of the day and year first above written.

This is one of the Senior Notes due 2010, referred to in the within-mentioned Indenture.

Dated:	THE BANK OF NEW YORK, as Trustee

A-1-3

1. Indenture. This Note is one of a duly authorized issue of Notes of the Company designated as its Senior Notes due 2010 (herein called the “Notes”). The Notes are issued under an indenture (herein called the “Indenture”) dated as of , 2003 by and between the Company and The Bank of New York, as trustee (herein called the “Trustee,” which term includes any successor Trustee under this Indenture) and as Paying Agent and Registrar (in each capacity, the “Paying Agent” and “Registrar”), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties, obligations and immunities thereunder of the Company, the Trustee, the Paying Agent, the Registrar and the Holders of the Notes, and of the terms upon which the Notes are, and are to be, authenticated and delivered.

The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) (the “TIA”), as in effect on the date of the Indenture. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders of Notes are referred to the Indenture and the TIA for a statement of such terms.

No reference herein to the Indenture and no provisions of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Note at the times, place, and rate, and in the coin or currency, herein prescribed.

(b) [Reserved]

(c) If, as a result of any amendment to, or change in, the laws (or any regulation or rulings thereunder) of Mexico or any political subdivision or taxing authority thereof or therein affecting taxation or any amendment to or change in an official interpretation, administration or application of such laws, regulations or rulings (including a holding by a court of competent jurisdiction), which amendment or change of such laws, regulations or rulings becomes effective on or after the date on which the Notes are originally issued, the Company would be or would become obligated, after taking reasonable measures available to it to avoid such requirement, to pay Additional Amounts in respect of any Note pursuant to the terms and conditions thereof in excess of the Additional Amounts that the Company would be obligated to pay if payments made on the Notes were subject to withholding or deduction of Mexican Taxes at a rate of 4.9 percent (“Excessive Additional Amounts”), then, at the Company’s option, the Notes may be redeemed in whole, but not in part, at any time, on giving not less than 30 nor more than 60 days’ notice mailed to the Trustee at a cash price equal to the sum of (i) 100% of the principal amount thereof on the date of redemption, (ii) the accrued and unpaid interest, if any, thereon to the date of redemption, and (iii) any Additional Amounts which would otherwise be payable (the “Redemption Price”); provided, however, that (1) no such notice of redemption may be given earlier than 90 days prior to the earliest date on which, but for such redemption, the Company would be obligated to pay such Excessive Additional Amounts were a payment on the Notes then be due and (2) at the time such notice of redemption is given, such obligation to pay such Additional Amounts (including any Excessive Additional Amounts) remains in effect.

A-1-4

(d) Unless the Company defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Notes or portions thereof called for redemption.

3. Offers to Purchase. Sections 10.10 and 10.15 of the Indenture provide that upon the occurrence of a Change of Control and following certain Asset Sales, and subject to certain conditions and limitations contained therein, the Company shall make an offer to purchase all or a portion of the Notes in accordance with the procedures set forth in the Indenture.

4. Defaults and Remedies. If an Event of Default occurs and is continuing, the principal of all of the Outstanding Notes, plus all accrued and unpaid interest, if any, to and including the date the Notes are paid, may be declared due and payable in the manner and with the effect provided in the Indenture.

5. Defeasance. The Indenture contains provisions (which provisions apply to this Note) for defeasance at any time of (a) the entire indebtedness of the Company on this Note and (b) certain restrictive covenants and related Defaults and Events of Default, in each case upon compliance by the Company with certain conditions set forth therein.

The Indenture permits, with certain exceptions as provided therein, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Notes at the time Outstanding, on behalf of the Holders of all the Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past Defaults under the Indenture and this Note and their consequences.

Each holder of Notes by accepting a Note waives and releases all such liability (such waiver will not constitute a waiver of liabilities under the Federal securities laws, however, if it is the view of the SEC that such a waiver would be against public policy).

As provided in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes of a different authorized denomination, as requested by the Holder surrendering the same.
