SECTION 103. COMPLIANCE CERTIFICATES AND OPINIONS.

Except as otherwise expressly provided by this Indenture, upon any application or request by the Company to the Trustee to take any action under any provision of this Indenture, the Company shall furnish to the Trustee an Officers' Certificate stating that all conditions precedent, if any (including any covenants the compliance with which constitutes a condition precedent), provided for in this Indenture relating to the proposed action have been complied with and an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent, if any (including any covenants the compliance with which constitutes a condition precedent), have been complied with, except that in the case of any such application or request as to which the furnishing of such documents is specifically required by any provision of this Indenture relating to such particular application or request, no additional certificate or opinion need be furnished.

SECTION 104. FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one

document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

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

SECTION 105. ACTS OF HOLDERS; RECORD DATES.

(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. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments and so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or the holding of any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner provided in Section 1306.

The Company may set in advance a record date for purposes of determining the identity of Holders of Registered Securities entitled to vote or consent to any action by vote or consent authorized or permitted under this Indenture, which record date shall be the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee prior to such solicitation. If a record date is fixed, those persons who were Holders of Outstanding Registered Securities at such record date (or their duly designated proxies), and only those persons, shall be entitled with respect to such Securities to take such action by vote or consent or to revoke any vote or consent previously given, whether or not such persons continue to be Holders after such record date. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice thereof to be given to the Trustee in writing in the manner provided in
Section 106 and to the relevant Holders as set forth in Section 107.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

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

(d) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security. Any Holder or subsequent Holder may revoke the request, demand, authorization, direction, notice, consent or other Act as to his Security or portion of his Security; PROVIDED, HOWEVER, that such revocation shall be effective only if the Trustee receives the notice of revocation before the date the Act becomes effective.

SECTION 106. NOTICES, ETC., TO TRUSTEE AND 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,

(1) 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 and received by the Trustee at its Corporate Trust Office, Attention: Corporate Trust Administration, or

(2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it at the address of its principal office specified in the first paragraph of this Indenture or at any other address previously furnished in writing to the Trustee by the Company, Attention: Corporate Secretary.

SECTION 107. NOTICE TO HOLDERS; WAIVER.

Where this Indenture provides for notice to Holders of Securities of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at the address of such Holder as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice.

In case by reason of the suspension of regular mail service, or by reason of any other cause it shall be impracticable to give such notice to Holders of Registered Securities by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. In any case in which notice to Holders of Registered Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Registered Security, shall affect the sufficiency of such notice with respect to other Holders of Registered Securities.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

SECTION 108. CONFLICT WITH TRUST INDENTURE ACT.

If any provision hereof limits, qualifies or conflicts with any provision of the Trust Indenture Act or another provision hereof required to be included in this Indenture by any of the provisions of the Trust Indenture Act, such provision of the Trust Indenture Act shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the former provision shall be deemed to apply to this Indenture as so modified or to be excluded.

SECTION 109. EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

SECTION 110. SUCCESSORS AND ASSIGNS.

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

SECTION 111. SEPARABILITY CLAUSE.

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

SECTION 112. BENEFITS OF INDENTURE.

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

SECTION 113. GOVERNING LAW.

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

SECTION 114. LEGAL HOLIDAYS.

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

SECTION 115. CORPORATE OBLIGATION.

No recourse may be taken, directly or indirectly, against any incorporator, subscriber to the capital stock, stockholder, officer, director or employee of the Company or the Trustee or of any predecessor or successor of the Company or the Trustee with respect to the Company's obligations on the Securities or the obligations of the Company or the Trustee under this Indenture or any certificate or other writing delivered in connection herewith.

ARTICLE TWO

SECURITY FORMS

SECTION 201. FORMS GENERALLY.

The Securities of each series shall be Registered Securities and shall be in substan tially such form or forms (including temporary or permanent global form) as shall be established by or pursuant to a Board Resolution or in one or more indentures supplemental hereto, in each case with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Indenture and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with the rules of any securities exchange or as may, consistently herewith, be determined by the officers executing such Securities, as evidenced by their execution of the Securities. If temporary Securities of any series are issued in global form as permitted by Section 304, the form thereof shall be established as provided in the preceding sentence. A copy of the Board Resolution establishing the form or forms of Securities of any series (or any such temporary global Security) shall be delivered to the Trustee at or prior to the delivery of the Company Order contemplated by Section 303 for the authentication and delivery of such Securities (or any such temporary global Security).

The definitive Securities shall be printed, lithographed or engraved on steel engraved borders or may be produced in any other manner, all as determined by the officers executing such Securities, as evidenced by their execution thereof.

SECTION 202. FORM OF TRUSTEE'S CERTIFICATE OF AUTHENTIFICATION.

The Trustee's certificate of authentification shall be in substantially the following form:

"This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

TEXAS COMMERCE BANK NATIONAL
ASSOCIATION, AS TRUSTEE

By_____________________________________
AUTHORIZED OFFICER".

SECTION 203. SECURITIES IN GLOBAL FORM.

If Securities of a series are issuable in global form, as contemplated by Section 301, then, notwithstanding clause (10) of Section 301 and the provisions of Section 302, any such Security shall represent such of the Outstanding Securities of such series as shall be specified therein and may provide that it shall represent the aggregate amount of Outstanding Securities from time to time endorsed thereon and that the aggregate amount of Outstanding Securities represented thereby may from time to time be reduced to reflect exchanges. Any endorsement of a Security in global form to reflect the amount, or any increase or decrease in the amount, of Outstanding Securities represented thereby shall be made by the Trustee in such manner and upon instructions given by such Person or Persons as shall be specified in such Security or in a Company Order to be delivered to the Trustee pursuant to Section 303 or Section 304. Subject to the provisions of Section 303 and, if applicable, Section 304, the Trustee shall deliver and redeliver any Security in permanent global form in the manner and upon instructions given by the Person or Persons specified in such Security or in the applicable Company Order. If a Company Order pursuant to
Section 303 or 304 has been, or simultaneously is, delivered, any instructions by the Company with respect to endorsement or delivery or redelivery of a Security in global form shall be in writing but need not comply with Section 103 and need not be accompanied by an Opinion of Counsel.

The provisions of the last sentence of Section 303 shall apply to any Security in global form if such Security was never issued and sold by the Company and the Company delivers to the Trustee the Security in global form together with written instructions (which need not comply with Section 103 and need not be accompanied by an Opinion of Counsel) with regard to the reduction in the principal amount of Securities represented thereby, together with the written statement contemplated by the last sentence of Section 303.

Notwithstanding the provisions of Sections 201 and 307, unless otherwise specified as contemplated by Section 301, payment of principal of (and premium, if any) and interest on any Security in permanent global form shall be made to the Person or Persons specified therein.

Notwithstanding the provisions of Section 308 and except as provided in the preceding paragraph, the Company, the Trustee and any agent of the Company or of the Trustee shall treat a Person as the Holder of such principal amount of Outstanding Securities represented by a global Security as shall be specified in a written statement, if any, of the Holder of such global Security, which is produced to the Security Registrar by such Holder.

Global Securities may be issued in either temporary or permanent form. Permanent global Securities will be issued in definitive form.

SECTION 204. BOOK-ENTRY SECURITIES.

Notwithstanding any provision of this Indenture to the contrary:

(a) At the discretion of the Company, any Registered Security may be issued from time to time, in whole or in part, in permanent global form registered in the name of a Depositary, or its nominee. Each such Registered Security in permanent global form is hereafter referred to as a "Book-Entry Security." Subject to Section 303, upon such election, the Company shall execute, and the Trustee or an Authenticating Agent shall authenticate and deliver, one or more Book-Entry Securities that (i) are denominated in an amount equal to the aggregate principal amount of the Outstanding Securities of such series if elected in whole or such lesser amount if elected in part, (ii) are registered in the name of the Depositary or its nominee, (iii) are delivered by the Trustee or an Authenticating Agent to the Depositary or pursuant to the Depositary's instructions and (iv) bear a legend in substantially the following form (or such other form as the Depositary and the Company may agree upon):

UNLESS THIS SECURITY IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF
[THE DEPOSITARY], TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF

TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF [NOMINEE OF THE DEPOSITARY] OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF [THE DEPOSITARY] (AND ANY PAYMENT IS MADE TO [NOMINEE OF THE DEPOSITARY] OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF [THE DEPOSITARY]), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, [NOMINEE OF THE DEPOSITARY], HAS AN INTEREST HEREIN.

(b) Any Book-Entry Security shall be initially executed and delivered as provided in Section 303. Notwithstanding any other provision of this Indenture, unless and until it is exchanged in whole or in part for Registered Securities not issued in global form, a Book-Entry Security may not be transferred except as a whole by the Depositary to a nominee of such Depositary, by a nominee of such Depositary to such Depositary or another nominee of such Depositary, or by such Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.

(c) If at any time the Depositary notifies the Company or the Trustee that it is unwilling or unable to continue as Depositary for any Book-Entry Securities, the Company shall appoint a successor Depositary, whereupon the retiring Depositary shall surrender or cause the surrender of its Book-Entry Security or Securities to the Trustee. The Trustee shall promptly notify the Company upon receipt of such notice. If a successor Depositary has not been so appointed by the effective date of the resignation of the Depositary, the Book-Entry Securities will be issued as Registered Securities not issued in global form, in an aggregate principal amount equal to the principal amount of the Book-Entry Security or Securities theretofore held by the Depositary.

The Company may at any time and in its sole discretion determine that the Securities shall no longer be Book-Entry Securities represented by a global certificate or certificates, and will so notify the Depositary. Upon receipt of such notice, the Depositary shall promptly surrender or cause the surrender of its Book-Entry Security or Securities to the Trustee. Concurrently therewith, Registered Securities not issued in global form will be issued in an aggregate principal amount equal to the principal amount of the Book-Entry Security or Securities theretofore held by the Depositary.

Upon any exchange of Book-Entry Securities for Registered Securities not issued in global form as set forth in this Section 204(c), such Book-Entry Securities shall be cancelled by the Trustee, and Securities issued in exchange for such Book-Entry Securities pursuant to this Section shall be registered in such names and in such authorized denominations as the Depositary for such Book-Entry Securities, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee or any Authenticating Agent shall deliver such Securities to the persons in whose names such Securities are so registered.

(d) The Company and the Trustee shall be entitled to treat the Person in whose name any Book-Entry Security is registered as the Holder thereof for all purposes of the Indenture and any applicable laws, notwithstanding any notice to the contrary received by the Trustee or the Company; and the Trustee and the Company shall have no responsibility for transmitting payments to, communication with, notifying, or otherwise dealing with any beneficial owners of any Book-Entry Security. Neither the Company nor the Trustee shall have any responsibility or obligations, legal or otherwise, to the beneficial owners or to any other party including the Depositary, except for the Holder of any Book-Entry Security; PROVIDED HOWEVER, notwithstanding anything herein to the contrary, (i) for the purposes of determining whether the requisite principal amount of Outstanding Securities have given, made or taken any request, demand, authorization, direction, notice, consent, waiver, instruction or other action hereunder as of any date, the Trustee shall treat any Person specified in a written statement of the Depositary with respect to any Book-Entry Securities as the Holder of the principal amount of such Securities set forth therein and (ii) nothing herein shall

prevent the Company, the Trustee, or any agent of the Company or Trustee, from giving effect to any written certification, proxy or other authorization furnished by a Depositary with respect to any Book-Entry Securities, or impair, as between a Depositary and holders of beneficial interests in such Securities, the operation of customary practices governing the exercise of the rights of the Depositary as Holder of such Securities.

(e) So long as any Book-Entry Security is registered in the name of a Depositary or its nominee, all payments of the principal of (and premium, if any) and interest on such Book-Entry Security and redemption thereof and all notices with respect to such Book Entry Security shall be made and given, respectively, in the manner provided in the arrangements of the Company with such Depositary.

If any of the terms of the series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action together with such Board Resolution shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers' Certificate setting forth the terms of the series.

SECTION 302. DENOMINATIONS.

The Securities of each series shall be issuable in such denominations as shall be specified as contemplated by Section 301. In the absence of any such provisions with respect to the Securities of any series, the Registered Securities of such series denominated in Dollars shall be issuable in denominations of $1,000 and any integral multiple thereof. Unless otherwise provided as contemplated by Section 301 with respect to any series of Securities, any Securities of a series denominated in a currency other than Dollars shall be issuable in denominations that are the equivalent, as determined by the Company by reference to the noon buying rate in The City of New York for cable transfers for such currency ("Exchange Rate"), as such rate is reported or otherwise made available by the Federal Reserve Bank of New York, on the applicable issue date for such Securities, of $1,000 and any integral multiple thereof.

SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

The Securities shall be executed on behalf of the Company by its Chairman of the Board, its President, its Treasurer or one of its Vice Presidents, under its corporate seal reproduced thereon or affixed thereto attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile. Coupons shall bear the facsimile signature of the Chairman of the Board, President, Treasurer or any Vice President of the Company.

Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver such Securities as in this Indenture provided and not otherwise.

If the form or terms of the Securities of the series have been established in or pursuant to one or more Board Resolutions as permitted by Sections 201 and 301, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive (in addition to the other documents required by Section 103 hereof), and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating,

(a) if the form of such Securities has been established by or pursuant to Board Resolution as permitted by Section 201, that such form has been established in conformity with the provisions of this Indenture;

(b) if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 301, that such terms have been established in conformity with the provisions of this Indenture; and

(c) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute legal, valid and binding obligations of the Company, enforceable in accordance with their terms, except as such enforcement is subject to the effect of bankruptcy, insolvency, fraudulent conveyance, reorganization or other laws relating to or affecting creditors' rights, and general principles of equity (regardless of whether such enforcement is considered in a proceeding in equity or at law).

If such form or terms have been so established, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee's own

rights, duties or immunities under the Securities and this Indenture or otherwise in a manner not reasonably acceptable to the Trustee.

Each Registered Security shall be dated the date of its authentication.

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 309 together with a written statement (which need not comply with Section 103 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

SECTION 304. TEMPORARY SECURITIES.

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

Except in the case of temporary Securities in global form (which shall be exchanged in accordance with the provisions of the following paragraphs), if temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of the same series of authorized denominations. Until so exchanged the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series.
All Outstanding temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder.

SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

The Company shall cause to be kept for each series of Securities at one of the offices or agencies maintained pursuant to Section 1002 a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Registered Securities and of transfers of Registered Securities of such series. The Trustee is hereby initially appointed "Security Registrar" for the purpose of registering Securities and transfers of Securities as herein provided.

Upon surrender for registration of transfer of any Registered Security of any series at the office or agency in a Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Registered Securities of the same series and of like tenor, of any authorized denominations and of a like aggregate principal amount.

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

Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 301, any permanent global Security shall be exchangeable only as provided in this paragraph. If the beneficial owners of interests in a permanent global Security are entitled to exchange such interest for Securities of such series and of like tenor and principal amount of another authorized form and denomination, as specified as contemplated by Section 301, then without unnecessary delay but in any event not later than the earliest date on which such interests may be so exchanged, the Company shall deliver to the Trustee definitive Securities of that series in an aggregate principal amount equal to the principal amount of such permanent global Security, executed by the Company. On or after the earliest date on which such interests may be so exchanged, such permanent global Security shall be surrendered from time to time in accordance with instructions given to the Trustee and the Depositary (which instructions shall be in writing but need not comply with Section 103 or be accompanied by an Opinion of Counsel) or such other depositary as shall be specified in the Company Order with respect thereto to the Trustee, as the Company's agent for such purpose, to be exchanged, in whole or in part, for definitive Securities of the same series without charge and the Trustee shall authenticate and deliver, in exchange for each portion of such permanent global Security, a like aggregate principal amount of other definitive Securities of the same series of authorized denominations and of like tenor as the portion of such permanent global Security to be exchanged; PROVIDED, HOWEVER, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities of that series is to be redeemed and ending on the relevant Redemption Date. Promptly following any such exchange in part, such permanent global Security marked to evidence the partial exchange shall be returned by the Trustee to the Depositary or such other depositary referred to above in accordance

with the instructions of the Company referred to above. If a Registered Security is issued in exchange for any portion of a permanent global Security after the close of business at the office or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but will be payable on such Interest Payment Date or proposed for payment, as the case may be, only to the Person to whom interest in respect of such portion of such permanent global Security is payable in accordance with the provisions of this Indenture.

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

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

No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchange pursuant to Section 304, 906 or 1107 not involving any transfer.

The Company shall not be required (i) to issue, register the transfer of or exchange Securities of any series during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Securities of such series selected for redemption and ending at the close of business on the day of the mailing of the relevant notice of redemption or (ii) to register the transfer of or exchange any Registered Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.

SECTION 306. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon its request the Trustee shall authenticate and deliver,

in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

If, after the delivery of such replacement Security, a bona fide purchaser of the original Security in lieu of which such replacement Security was issued presents for payment or registration such original Security, the Trustee shall be entitled to recover such replacement Security from the person to whom it was delivered or any person taking therefrom, except a bona fide purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Trustee or the Company in connection therewith.

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

Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fee and expenses of the Trustee) connected therewith.

Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

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

SECTION 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

Interest on any Registered Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. Unless otherwise provided with respect to the Securities of any series, payment of interest may be made at the option of the Company by check mailed or delivered to the address of any Person entitled thereto as such address shall appear in the Security Register.

Any interest on any Registered Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Registered Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Registered Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Registered Securities of such series at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in an Authorized Newspaper, but such publication shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Registered Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

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

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

SECTION 308. PERSONS DEEMED OWNERS.

Prior to due presentment of a Registered Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Registered Security is registered as the owner of such Registered Security for the purpose

of receiving payment of principal of (and premium, if any) and (subject to Sections 305 and 307) interest on such Registered Security and for all other purposes whatsoever, whether or not such Security 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 309. CANCELLATION.

All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Registered Securities so delivered shall be promptly cancelled by the Trustee. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of as directed by a Company Order; PROVIDED that the Trustee shall not be required to destroy such Securities.

SECTION 310. COMPUTATION OF INTEREST.

Except as otherwise specified as contemplated by Section 301 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a year comprising twelve 30-day months.

SECTION 311. CUSIP NUMBERS.

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

(6) no Default or Event of Default with respect to the Securities of such issue shall have occurred and be continuing on the date of such deposit or, in so far as clause (5) or (6) of Section 501 is concerned, at any time in the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

For the purposes of this Indenture, "U.S. Government Obligations" means direct noncallable obligations of, or noncallable obligations the payment of principal of and interest on which is guaranteed by, the United States of America, or to the payment of which obligations or guarantees the full faith and credit of the United States of America is pledged, or beneficial interests in a trust the corpus of which consists exclusively of money or such obligations or a combination thereof.

If any Outstanding Securities of such series are to be redeemed prior to their Stated Maturity, whether pursuant to any optional redemption provisions or in accordance with any mandatory sinking fund requirement, the trust agreement referred to in subclause (B) of clause (1) of this Section 401 shall provide therefor and the Company shall make such arrangements as are satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company.

Notwithstanding the satisfaction and discharge of this Indenture with respect to the Outstanding Securities of such series pursuant to this
Section 401, the obligations of the Company to the Trustee under Section 607, the obligations of the Trustee to any Authenticating Agent under Section 614 and, except for a discharge pursuant to subclause (A) of clause (1) of this

REMEDIES

SECTION 501. EVENTS OF DEFAULT.

"Event of Default," wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), unless it is either inapplicable to a particular series or it is specifically deleted or modified in or pursuant to the supplemental indenture or Board Resolution establishing such series of Securities or in the form of Security for such series:

(1) default in the payment of any interest or any Additional Amounts upon any Security of that series when such interest or Additional Amounts become due and payable, and continuance of such default for a period of 30 days;

(2) default in the payment of the principal of (or premium, if any, on) any Security of that series at its Maturity;

(3) default in the deposit of any sinking fund payment, when and as due by the terms of a Security of that series and continuance of such default for a period of 30 days;

(4) default in the performance or breach of any covenant of the Company in this Indenture (other than a covenant a default in whose performance or whose breach is elsewhere in this Section 501 specifically dealt with or which has expressly been included in this Indenture solely for the benefit of one or more series of Securities other than that series), and continuance of such default or breach for a period of 90 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of all Outstanding Securities a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice of Default" hereunder; or

(5) the entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable federal or state bankruptcy, insolvency, reorganization or other similar law or (B) a decree or order adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any applicable federal or state law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 90 consecutive days; or

(6) the commencement by the Company of a voluntary case or proceeding under any applicable federal or state bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable federal or state bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it, of a petition or answer or consent seeking reorganization or relief under any applicable federal or state law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or similar official of the Company or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company in furtherance of any such action; or

(7) any other Event of Default provided with respect to Securities of that series.

Notwithstanding the foregoing provisions of this Section 501, if the principal of (and premium, if any) or any interest on or Additional Amounts with respect to any Security is payable in a currency or currencies (including a composite currency) other than Dollars and such currency (or currencies) is (or are) not available to the Company for making payment thereof due to the imposition of exchange controls or other circumstances beyond the control of the Company (a "Conversion Event"), the Company will be entitled to satisfy its obligations to Holders of the Securities by making such payment in Dollars in an amount equal to the Dollar equivalent of the amount payable in such other currency, as determined by the Company by reference to the Exchange Rate, as such Exchange Rate is certified for customs purposes by the Federal Reserve Bank of New York on the date of such payment, or, if such rate is not then available, on the basis of the most recently available Exchange Rate. Notwithstanding the foregoing provisions of this Section 501, any payment made under such circumstances in Dollars where the required payment is in a currency other than Dollars will not constitute an Event of Default under this Indenture.

Promptly after the occurrence of a Conversion Event, the Company shall give written notice thereof to the Trustee; and the Trustee, promptly after receipt of such notice, shall give notice thereof in the manner provided in Section 107 to the Holders. Promptly after the making of any payment in Dollars as a result of a Conversion Event, the Company shall give notice in the manner provided in Section 107 to the Holders, setting forth the applicable Exchange Rate and describing the calculation of such payments.

SECTION 502. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

If an Event of Default with respect to any Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of (i) the series affected by such default (in the case of an Event of Default described in clause (1), (2), (3) or (7) of Section 501) or (ii) all series of Securities (subject to the immediately following sentence, in the case of an Event of Default

described in clause (4) of Section 501) may declare the principal amount (or, if any such Securities are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of that series) of all of the Securities of the series affected by such default or all series, as the case may be, to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable. If an Event of Default described in clause (5) or (6) of Section 501 shall occur, the principal amount of the Outstanding Securities of all series IPSO FACTO shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

At any time after such a declaration of acceleration with respect to Securities of any series (or of all series, as the case may be) has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series (or of all series, as the case may be), by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if

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

(A) all overdue interest on, and any Additional Amounts with respect to, all Securities of that series (or of all series, as the case may be),

(B) the principal of (and premium, if any, on) any Securities of that series (or of all series, as the case may be) which have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in such Securities (in the case of Original Issue Discount Securities, the Securities' Yield to Maturity),

(C) to the extent that payment of such interest is lawful, interest upon overdue interest and any Additional Amounts at the rate or rates prescribed therefor in such Securities (in the case of Original Issue Discount Securities, the Securities' Yield to Maturity), and

(D) all sums paid or advanced by the Trustee hereunder, the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and all other amounts due the Trustee under Section 607 hereof;

and

(2) all Events of Default with respect to Securities of that series (or of all series, as the case may be), other than the nonpayment of the principal of Securities of that series (or of all series, as the case may be) which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 512.

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

SECTION 503. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

The Company covenants that if

(1) default is made in the payment of any installment of interest on, or any Additional Amounts with respect to, any Security of any series when such interest or Additional Amounts shall have become due and payable and such default continues for a period of 30 days, or

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal (and premium, if any) and interest and Additional Amounts and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal (and premium, if any) and on any overdue interest and Additional Amounts, at the rate or rates prescribed therefor in such Securities (or in the case of Original Issue Discount Securities, the Securities' Yield to Maturity), and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated.

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

SECTION 504. TRUSTEE MAY FILE PROOFS OF CLAIM.

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal (or lesser amount in the case of Original Issue Discount Securities) of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal (premium, if any), interest or

Additional Amounts) shall be entitled and empowered, by intervention in such proceeding or otherwise,

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

(ii) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceedings; PROVIDED, HOWEVER, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official.

SECTION 505. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES OR COUPONS.

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

SECTION 506. APPLICATION OF MONEY COLLECTED.

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

FIRST: To the payment of all amounts due the Trustee under Section 607;

SECOND: To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest and any Additional Amounts on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium, if any), interest and Additional Amounts, respectively; and

THIRD: The balance, if any, to the Company.

To the fullest extent allowed under applicable law, if for the purpose of obtaining judgment against the Company in any court it is necessary to convert the sum due in respect of the principal of (or premium, if any) or interest on the Securities of any series (the "Required Currency") into a currency in which a judgment will be rendered (the "Judgment Currency"), the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on the New York Business Day next preceding that on which final judgment is given. Neither the Company nor the Trustee shall be liable for any shortfall nor shall it benefit from any windfall in payments to Holders of Securities under this Section caused by a change in exchange rates between the time the amount of a judgment against it is calculated as above and the time the Trustee converts the Judgment Currency into the Required Currency to make payments under this Section to Holders of Securities, but payment of such judgment shall discharge all amounts owed by the Company on the claim or claims underlying such judgment.

SECTION 507. LIMITATION ON SUITS.

Subject to Section 508, no Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless

(1) an Event of Default with respect to Securities of such series shall have occurred and be continuing and such Holder has previously given written notice to the Trustee of such continuing Event of Default;

(2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series 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;

(3) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request;

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

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

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

SECTION 508. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND INTEREST.

Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of (and premium, if any) and (subject to
Section 307) interest on and any Additional Amounts with respect to such Security on the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment on or after such respective dates, and such rights shall not be impaired or affected without the consent of such Holder.

SECTION 509. RESTORATION OF RIGHTS AND REMEDIES.

If the Trustee or any Holder of any Security has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, 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 510. RIGHTS AND REMEDIES CUMULATIVE.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 511. DELAY OR OMISSION NOT WAIVER.

No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy

given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 512. CONTROL BY HOLDERS.

With respect to Securities of any series, the Holders of a majority in principal amount of the Outstanding Securities of such series 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, relating to or arising under an Event of Default described in clause (1), (2), (3) or (7) of Section 501, and with respect to all Securities the Holders of a majority in principal amount of all Outstanding Securities shall have the right to direct the time, method and place of conducting any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, not relating to or arising under such an Event of Default, PROVIDED that in each such case:

(1) the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, determines that the action so directed may not lawfully be taken or would conflict with this Indenture or if the Trustee in good faith shall, by a Responsible Officer, determine that the proceedings so directed would involve it in personal liability or be unjustly prejudicial to the Holders not taking part in such direction, and

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

SECTION 513. WAIVER OF PAST DEFAULTS.

Subject to Sections 508 and 902, the Holders of a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect to such series and its consequences, and the Holders of a majority in principal amount of all Outstanding Securities may on behalf of the Holders of all Securities waive any other past default hereunder and its consequences, except in each case a default

(1) in the payment of the principal of (or premium, if any) or interest on or any Additional Amounts with respect to any Security, or

(2) in respect of a covenant or provision hereof that under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security affected.

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

SECTION 514. UNDERTAKING FOR COSTS.

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

SECTION 515. WAIVER OF STAY OR EXTENSION 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 wherever enacted, now or at any time hereafter in force, 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.

SECTION 612. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

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

SECTION 614. APPOINTMENT OF AUTHENTICATING AGENT.

The Trustee may appoint an Authenticating Agent or Agents that shall be authorized to act on behalf of the Trustee to authenticate Securities issued upon original issue and upon exchange, registration of transfer or partial redemption or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder.

If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section 614, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in

accordance with the provisions of this Section 614, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this
Section 614.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, PROVIDED such corporation shall be otherwise eligible under this Section 614, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section 614, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall mail written notice of such appointment by first-class mail, postage prepaid, to all Holders as their names and addresses appear in the Security Register. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section 614.

The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section 614, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 607.

If Securities of a series are issuable only as Registered Securities, the Company will maintain in each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

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

SECTION 1003. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

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

Whenever the Company shall have one or more Paying Agents for any series of Securities, the Company will, on or before each due date of the principal of (and premium, if any) or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the

benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

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

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

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

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of (and premium, if any) or interest on any Security of any series and remaining unclaimed for three years after such principal (and premium, if any) or interest has become due and payable shall, unless otherwise required by mandatory provisions of applicable escheat, or abandoned or unclaimed property law, be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; PROVIDED, HOWEVER, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in an Authorized Newspaper in The Borough of Manhattan, The City of New York and in such other Authorized Newspapers as the Trustee shall deem appropriate, notice that such money remains unclaimed and that, after a date specified herein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will, unless otherwise required by mandatory provisions of applicable escheat, or abandoned or unclaimed property law, be repaid to the Company.

Section 314(a)(4) of the Trust Indenture Act and stating that a review of the activities of the Company during such year and of performance under this Indenture has been made under the supervision of the signers thereof and whether or not to the best of their knowledge, based upon such review, the Company is in default in the performance, observance or fulfillment of any of its covenants and other obligations under this Indenture, and if the Company shall be in default, specifying each such default known to them and the nature and status thereof. One of the officers signing the Officers' Certificate delivered pursuant to this Section 1005 shall be the principal executive, financial or accounting officer of the Company.

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

The Company may omit in any particular instance to comply with any covenant or condition set forth in Section 1005, or any covenant added for the benefit of any series of Securities as contemplated by Section 301 (unless otherwise specified pursuant to Section 301) if before or after the time for such compliance the Holders of a majority in principal amount of the Outstanding Securities of all series affected by such omission (acting as one class) shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such covenant or condition, but no such waiver shall extend to or affect such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such covenant or condition shall remain in full force and effect.

SECTION 1007. ADDITIONAL AMOUNTS.

If the Securities of a series expressly provide for the payment of Additional Amounts, the Company will pay to the Holder of any Security of such series Additional Amounts as expressly provided therein. Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any premium or interest on, or in respect of, any Security of any series or the net proceeds received from the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this Section 1007 to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to the provisions of this Section 1007 and express mention of the payment of

Additional Amounts (if applicable) in any provisions hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made.

If the Securities of a series provide for the payment of Additional Amounts, at least 10 days prior to the first Interest Payment Date with respect to that series of Securities (or if the Securities of that series will not bear interest prior to Maturity, the first day on which a payment of principal and any premium is made), and at least 10 days prior to each date of payment of principal and any premium or interest if there has been any change with respect to the matters set forth in the below-mentioned Officers' Certificate, the Company shall furnish the Trustee and the Company's principal Paying Agent or Paying Agents, if other than the Trustee, with an Officers' Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of and any premium or interest on the Securities of that series shall be made to Holders of Securities of that series who are United States Aliens without withholding for or on account of any tax, assessment or other governmental charge described in the Securities of that series. If any such withholding shall be required, then such Officers' Certificate shall specify by country the amount, if any, required to be withheld on such payments to such Holders of Securities and the Company will pay to such Paying Agent the Additional Amounts required by this Section. The Company covenants to indemnify the Trustee and any Paying Agent for, and to hold them harmless against any loss, liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers' Certificate furnished pursuant to this
Section 1007.

SECTION 1304. QUORUM; ACTION.

The Persons entitled to vote a majority in aggregate principal amount of the Outstanding Securities of a series shall constitute a quorum for a meeting of Holders of Securities of such series. In the absence of a quorum within 30 minutes of the time appointed for any such meeting, the meeting shall, if convened at the request of Holders of Securities of such series, be dissolved. In any other case, the meeting may be adjourned for a period of not less than 10 days as determined by the chairman of the meeting prior to the adjournment of such meeting.

Except as limited by the proviso to Section 902, any resolution passed or decision taken at any meeting of Holders of Securities of any series duly held in accordance with this Section shall be binding on all the Holders of Securities of such series, whether or not present or represented at the meeting.

(a) The holding of Securities shall be proved in the manner specified in Section 105 and the appointment of any proxy shall be proved in the manner specified in Section 105. Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof specified in Section 105 or other proof.

(b) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Holders of Securities as provided in Section 1302(b), in which case the Company or the Holders of Securities of the series calling the meeting, as the case may be, shall appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in aggregate principal amount of the Outstanding Securities of such series represented at the meeting.

(c) At any meeting each Holder of a Security of such series and each proxy shall be entitled to one vote for each $1,000 principal amount of the Outstanding Securities of such series held or represented by him; PROVIDED, HOWEVER, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote, except as a Holder of a Security of such series or as a proxy.

(d) Any meeting of Holders of Securities of any series duly called pursuant to Section 1302 at which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority in aggregate principal amount of the Outstanding Securities of such series represented at the meeting; and the meeting may be held as so adjourned without further notice.

The vote upon any resolution submitted to any meeting of Holders of Securities of any series shall be by written ballots on which shall be subscribed the signatures of the Holders of Securities of such series or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities of such series held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the meeting. A record, at least in duplicate, of the proceedings of each meeting of Holders of Securities of any series shall be prepared by the secretary of the meeting and there shall be attached to such record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that such notice was given as provided in Section 1302 and, if applicable, Section 1304. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the Company, and another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated.

TO

INDENTURE

DATED AS OF

FIRST SUPPLEMENTAL INDENTURE, dated as of April 15, 1997, between TRANSOCEAN OFFSHORE INC., a corporation duly organized and existing under the laws of the State of Delaware (herein called the "Company"), having its principal office at 4 Greenway Plaza, Houston, Texas 77046, and TEXAS COMMERCE BANK NATIONAL ASSOCIATION, as Trustee (herein called the "Trustee"), the office of the Trustee at which at the date hereof its corporate trust business is principally administered being 600 Travis Street, Suite 1150, Houston, Texas 77002.

RECITALS OF THE COMPANY

The Company has executed and delivered to the Trustee an Indenture, dated as of April 15, 1997 (the "Original Indenture" and as supplemented by this First Supplemental Indenture, the "Indenture"), providing for the issuance from time to time of the Company's unsecured debentures, notes or other evidences of indebtedness (herein called the "Securities"), issuable in one or more series as in the Indenture provided. All capitalized terms used herein which are defined in the Original Indenture shall have the meanings assigned thereto in the Original Indenture unless otherwise defined herein.

Section 901(2) of the Original Indenture permits the execution of supplemental indentures without the consent of any Holders to add to the covenants of the Company for the benefit of the Holders of all or any series of Securities.

Pursuant to the foregoing authority, the Company proposes in and by this First Supplemental Indenture to supplement and amend the Original Indenture.

All things necessary to make this First Supplemental Indenture a valid agreement of the Company, in accordance with its terms, have been done.

NOW, THEREFORE, THIS FIRST SUPPLEMENTAL INDENTURE

WITNESSETH:

For and in consideration of the premises and the purchase of the Securities by the Holders thereof, it is mutually covenanted and agreed, for the equal and proportionate benefit of all Holders of the Securities or of series thereof, as follows:

ARTICLE ONE

DEFINITIONS AND OTHER PROVISIONS
OF GENERAL APPLICATION

The following definitions are hereby added to Section 101 of the Indenture:

"Consolidated Net Tangible Assets" means the total amount of assets (less applicable reserves and other properly deductible items) after deducting
(1) all current liabilities (excluding the

amount of those which are by their terms extendable or renewable at the option of the obligor to a date more than 12 months after the date as of which the amount is being determined) and (2) all goodwill, tradenames, trademarks, patents, unamortized debt discount and expense and other like intangible assets, all as set forth on the most recent balance sheet of the Company and its consolidated subsidiaries and determined in accordance with generally accepted accounting principles.

"Funded Debt" means indebtedness of the Company or a Subsidiary owning Restricted Property maturing by its terms more than one year after its creation and indebtedness classified as long-term debt under generally accepted accounting principles, and in each case ranking at least pari passu with the Securities.

"Lien" means any mortgage, pledge, lien, encumbrance, charge or security interest.

"Restricted Property" means (1) any drilling rig or drillship, or portion thereof, owned or leased by the Company or any Subsidiary and used for drilling offshore oil and gas wells, which, in the opinion of the Board of Directors, is of material importance to the business of the Company and its Subsidiaries taken as a whole, but no such drilling rig or drillship, or portion thereof, shall be deemed of material importance if its gross book value (before deducting accumulated depreciation) is less than 2% of Consolidated Net Tangible Assets, or (2) any shares of capital stock or indebtedness of any Subsidiary owning any such drilling rig or drillship.

"Sale and Leaseback Transaction" means any arrangement with any Person pursuant to which the Company or any Subsidiary leases any Restricted Property that has been or is to be sold or transferred by the Company or the Subsidiary to such Person, other than (1) temporary leases for a term, including renewals at the option of the lessee, of not more than three years, (2) leases between the Company and a Subsidiary or between Subsidiaries, (3) leases of a Restricted Property executed by the time of, or within 12 months after the latest of, the acquisition, the completion of construction or improvement, or the commencement of commercial operation of the Restricted Property, and (4) arrangements pursuant to any provision of law with an effect similar to the former Section 168(f)(8) of the Internal Revenue Code of 1954.

"Value" means, with respect to a Sale and Leaseback Transaction, an amount equal to the present value of the lease payments with respect to the term of the lease remaining on the date as of which the amount is being determined, without regard to any renewal or extension options contained in the lease, (including the effective interest rate on any original issue discount Securities) which are outstanding on the effective date of such Sale and Leaseback Transaction and which have the benefit of Section 1009.

ARTICLE TWO

COVENANTS

New Sections 1008 and 1009 are hereby added to Article Ten of the Indenture, to apply with respect to each series of Securities unless the Securities of any series expressly provide that such series shall not be entitled to the benefit of such Sections 1008 and 1009.

SECTION 1008. LIMITATION ON LIENS.

The Company shall not create, assume or suffer to exist any Lien on any Restricted Property to secure any debt of the Company, any Subsidiary or any other Person, or permit any Subsidiary so to do, without making effective provision whereby the Securities then outstanding and having the benefit of this
Section shall be secured by a Lien equally and ratably with such debt for so long as such debt shall be so secured, except that the foregoing shall not prevent the Company or any Subsidiary from creating, assuming or suffering to exist Liens of the following character:

(1) with respect to any series of Securities, any Lien existing on the date of issuance of the series;

(2) any Lien existing on Restricted Property owned or leased by a corporation at the time it becomes a Subsidiary;

(3) any Lien existing on Restricted Property at the time of the acquisition thereof by the Company or a Subsidiary;

(4) any Lien to secure any debt incurred prior to, at the time of, or within 12 months after the acquisition of Restricted Property for the purpose of financing all or any part of the purchase price thereof and any Lien to the extent that it secures debt which is in excess of such purchase price and for the payment of which recourse may be had only against such Restricted Property;

(5) any Lien to secure any debt incurred prior to, at the time of, or within 12 months after the completion of the construction and commencement of commercial operation, alteration, repair or improvement of Restricted Property for the purpose of financing all or any part of the cost thereof and any Lien to the extent that it secures debt which is in excess of such cost and for the payment of which recourse may be had only against such Restricted Property;

(6) any Lien securing debt of a Subsidiary owing to the Company or to another Subsidiary;

(7) any Lien in favor of the United States of America or any State thereof or any other country, or any agency, instrumentality of political subdivision of any of the foregoing, to secure partial, progress, advance or other payments or performance pursuant to the provisions of any contract or statute, or any Liens securing industrial development, pollution control, or similar revenue bonds;

(8) Liens imposed by law, such as mechanics', workmen's, repairmen's, materialmen's, carriers', warehousemen's, vendors' or other similar Liens arising in the ordinary course of business, or governmental (federal, state or municipal) Liens arising out of contracts for the sale of products or services by the Company or any Subsidiary, or deposits or pledges to obtain the release of any of the foregoing;

(9) pledges or deposits under workmen's compensation laws or similar legislation and Liens of judgments thereunder which are not currently dischargeable, or good faith deposits in connection with bids, tenders, contracts (other than for the payment of money) or leases to which the Company or any Subsidiary is a party, or deposits to secure public or statutory obligations of the Company or any Subsidiary, or deposits in connection with obtaining or maintaining self-insurance or to obtain the benefits of any law, regulation or arrangement pertaining to unemployment insurance, old age pensions, social security or similar matters, or deposits of cash or obligations of the United States of America to secure surety, appeal or customs bonds to which the Company or any Subsidiary is a party, or deposits in litigation or other proceedings such as, but not limited to, interpleader proceedings;

(10) Liens created by or resulting from any litigation or other proceeding which is being contested in good faith by appropriate proceedings, including Liens arising out of judgments or awards against the Company or any Subsidiary with respect to which the Company or such Subsidiary is in good faith prosecuting an appeal or proceedings for review; or Liens incurred by the Company or any Subsidiary for the purpose of obtaining a stay or discharge in the course of any litigation or other proceeding to which the Company or such Subsidiary is a party;

(11) Liens for taxes or assessments or governmental charges or levies not yet due or delinquent, or which can thereafter be paid without penalty, or which are being contested in good faith by appropriate proceedings;

(12) any extension, renewal or replacement (or successive extensions, renewals or replacements) in whole or in part of any Lien referred to in clauses (1) through (11) above, so long as the principal amount of the debt secured thereby does not exceed the principal amount of debt so secured at the time of the extension, renewal or replacement (except that, where an additional principal amount of debt is incurred to provide funds for the completion of a specific project, the additional principal amount, and any related financing costs, may

be secured by the Lien as well) and the Lien is limited to the same property subject to the Lien so extended, renewed or replaced (plus improvements on the property); and

(13) any Lien not permitted by clauses (1) through (12) above securing debt that, together with the aggregate outstanding principal amount of all other debt of the Company and its Subsidiaries secured by Liens which would otherwise be prohibited by the foregoing restrictions and the aggregate Value of existing Sale and Leaseback Transactions which would be subject to the restrictions of Section 1009 but for this clause
(13), does not at any time exceed 10% of Consolidated Net Tangible Assets.

SECTION 1009. LIMITATION ON SALE AND LEASEBACKS.

The Company shall not enter into any Sale and Leaseback Transaction covering any Restricted Property, nor permit any Subsidiary so to do, unless either:

(1) the Company or such Subsidiary would be entitled to incur debt, in a principal amount at least equal to the Value of such Sale and Leaseback Transaction, which is secured by Liens on the property to be leased (without equally and ratably securing the outstanding Securities) because such Liens would be of such character that no violation of the provisions of Section 1008 would result, or

(2) the Company during the six months immediately following the effective date of such Sale and Leaseback Transaction causes to be applied to (A) the acquisition of Restricted Property or (B) the voluntary retirement of Funded Debt (whether by redemption, defeasance, repurchase, or otherwise) an amount equal to the Value of such Sale and Leaseback Transaction.

TRANSOCEAN OFFSHORE INC.
7.45% NOTES DUE APRIL 15, 2027

This Security is one of a duly authorized issue of securities of the Company (herein called the "Securities"), issued and to be issued in one or more series under an Indenture, dated as of April 15, 1997 (herein called the "Indenture"), between the Company and Texas Commerce Bank National Association., as Trustee (herein called the "Trustee," which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, limited in aggregate principal amount to $100,000,000.

The Securities of this series may be redeemed at any time after April 15, 2007, at the option of the Company, in whole or from time to time in part, at a price equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, to the Redemption Date plus the Make-Whole Premium, if any (the "Redemption Price"). The amount of the Make-Whole Premium with respect to any Security of this series (or portion thereof) to be redeemed will be equal to the excess, if any, of: (i) the sum of the present values, calculated as of the Redemption Date, of: (A) each interest payment that, but for such redemption, would have been payable on the Security (or portion thereof) being redeemed on each Interest Payment Date occurring after the Redemption Date (excluding any accrued interest for the period prior to the Redemption Date); and (B) the principal amount that, but for such redemption, would have been payable at the final maturity of the Security (or portion thereof) being redeemed; over (ii) the principal amount of the Security (or portion thereof) being redeemed. The present values of interest and principal payments referred to in clause (i) above will be determined in accordance with generally accepted principles of financial analysis. Such present values will be calculated by discounting the amount of each payment of interest or principal from the date that each such payment would have been payable, but for the redemption, to the Redemption Date at a discount rate equal to the Treasury Yield (as defined below) plus 20 basis points.

The Make-Whole Premium shall be calculated by an independent investment banking institution of national standing appointed by the Company; provided, that if the Company fails to make such appointment at least 45 Business Days prior to the Redemption Date, or if the institution so appointed is unwilling or unable to make such calculation, such calculation shall be made by Goldman, Sachs & Co. or, if such firm is unwilling or unable to make such calculation, by an independent investment banking institution of national standing appointed by the Trustee (in any such case, an "Independent Investment Banker").

For purposes of determining the Make-Whole Premium, "Treasury Yield" means a rate of interest per annum equal to the weekly average yield to maturity of United States Treasury Notes that have a constant maturity that corresponds to the remaining term to maturity of the Securities of this series, calculated to the nearest 1/12th of a year (the "Remaining Term"). The Treasury Yield shall be determined as of the third Business Day immediately preceding the applicable Redemption Date. The weekly average yields of United States Treasury Notes shall be determined by reference to the most recent statistical release published by the Federal Reserve Bank of New York and designated "H.15 (519) Selected Interest Rates" or any successor release (the "H.15 Statistical Release"). If the H.15 Statistical Release sets forth a weekly average yield for United States Treasury Notes having a constant maturity that is the same as the Remaining Term, then the Treasury Yield shall be equal to such weekly average yield. In all other cases, the Treasury Yield shall be calculated by interpolation, on a straight-line basis, between the weekly average yields on the United States Treasury Notes that have a constant maturity closest to and greater than the Remaining Term and the United States Treasury Notes that have a constant maturity closest to and less than the Remaining Term (in each case as set forth in the H.15 Statistical Release). Any weekly average yields so calculated by interpolation shall be rounded to the nearest 1/100th of 1%, with any figure of 1/200% or above being rounded upward. If weekly average yields for United States Treasury Notes are not available in the H.15 Statistical Release or otherwise, then the Treasury Yield shall be calculated by interpolation of comparable rates selected by the Independent Investment Banker.

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

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

The Securities of this series may be repaid, at the option of the registered Holders thereof, on April 15, 2007, together with the accrued and unpaid interest, if any, to the date of such repayment. In order for the Holders to exercise this option, the Company must receive at its office or agency in New York, New York, during the period beginning on February 15, 2007 and ending at 5:00 p.m. (New York City time) on March 15, 2007 (or if such date is not a Business Day, the next succeeding Business Day), the Securities to be repaid with the form entitled "Option to Elect Repayment on April 15, 2007" below duly completed. Any such notice received by the Company during the period beginning on February 15, 2007 and ending at 5:00 p.m. (New York City time) on March 15, 2007 shall be irrevocable. The repayment option may be exercised by a Holder of the Securities of this series for less than the entire principal amount of such Securities held by such Holder so long as the principal amount to be repaid is equal to an integral multiple of $1,000.

Failure by the Company to repay the Securities of this series when required as described in the preceding paragraph shall result in an Event of Default.

So long as the Securities of this series are represented by a global Security, notice of exercise of the right of repayment must be given in accordance with the policies and procedures of the Depository Trust Company in effect at the time of exercise.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of this series at the time Outstanding, on behalf of the Holders of all Securities of this series, and specified percentages in principal amount of all Securities at the time Outstanding, on behalf of the holders of all Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

The Indenture contains provisions for the legal defeasance at any time of the entire indebtedness of the Company on this Security upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Security. Upon compliance with such provisions, the Company shall be deemed to have paid and discharged the entire indebtedness on this Security and the Company's obligation to pay the principal of (and premium, if any) and interest on this Security shall cease, terminate and be completely discharged.

The Indenture provides that no Holder of any Securities of any series may enforce any remedy under the Indenture except in the case of refusal or neglect of the Trustee to act after notice of default and request by the Holders of 25% in principal amount of Outstanding Securities in the series for which a remedy is sought to be enforced and the offer to the Trustee of reasonable indemnity.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall, without the consent of the Holder, alter or impair the right of the Holder, which is absolute and unconditional, to receive payment of principal of (and premium, if any) and interest on this Security at the times, place and rate, and in the coin or currency herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.

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

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue; and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

TRANSOCEAN OFFSHORE INC.
8.00% DEBENTURES DUE APRIL 15, 2027

This Security is one of a duly authorized issue of securities of the Company (herein called the "Securities"), issued and to be issued in one or more series under an Indenture, dated as of April 15, 1997 (herein called the "Indenture"), between the Company and Texas Commerce Bank National Association., as Trustee (herein called the "Trustee," which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, limited in aggregate principal amount to $200,000,000.

The Securities of this series may be redeemed at any time, at the option of the Company, in whole or from time to time in part, at a price equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, to the Redemption Date plus the Make-Whole Premium, if any (the "Redemption Price"). The amount of the Make-Whole Premium with respect to any Security of this series
(or portion thereof) to be redeemed will be equal to the excess, if any, of: (i)
the sum of the present values, calculated as of the Redemption Date, of: (A) each interest payment that, but for such redemption, would have been payable on the Security (or portion thereof) being redeemed on each Interest Payment Date occurring after the Redemption Date (excluding any accrued interest for the period prior to the Redemption Date); and (B) the principal amount that, but for such redemption, would have been payable at the final maturity of the Security (or portion thereof) being redeemed; over (ii) the principal amount of the Security (or portion thereof) being redeemed. The present values of interest and principal payments referred to in clause (i) above will be determined in accordance with generally accepted principles of financial analysis. Such present values will be calculated by discounting the amount of each payment of interest or principal from the date that each such payment would have been payable, but for the redemption, to the Redemption Date at a discount rate equal to the Treasury Yield (as defined below) plus 20 basis points.

The Make-Whole Premium shall be calculated by an independent investment banking institution of national standing appointed by the Company; provided, that if the Company fails to make such appointment at least 45 Business Days prior to the Redemption Date, or if the institution so appointed is unwilling or unable to make such calculation, such calculation shall be made by Goldman, Sachs & Co. or, if such firm is unwilling or unable to make such calculation, by an independent investment banking institution of national standing appointed by the Trustee (in any such case, an "Independent Investment Banker").

For purposes of determining the Make-Whole Premium, "Treasury Yield" means a rate of interest per annum equal to the weekly average yield to maturity of United States Treasury Notes that have a constant maturity that corresponds to the remaining term to maturity of the Securities of this series, calculated to the nearest 1/12th of a year (the "Remaining Term"). The Treasury Yield shall be determined as of the third Business Day immediately preceding the applicable Redemption Date. The weekly average yields of United States Treasury Notes shall be determined by reference to the most recent statistical release published by the Federal Reserve Bank of New York and designated "H.15 (519) Selected Interest Rates" or any successor release (the "H.15 Statistical Release"). If the H.15 Statistical Release sets forth a weekly average yield for United States Treasury Notes having a constant maturity that is the same as the Remaining Term, then the Treasury Yield shall be equal to such weekly average yield. In all other cases, the Treasury Yield shall be calculated by interpolation, on a straight-line basis, between the weekly average yields on the United States Treasury Notes that have a constant maturity closest to and greater than the Remaining Term and the United States Treasury Notes that have a constant maturity closest to and less than the Remaining Term (in each case as set forth in the H.15 Statistical Release). Any weekly average yields so calculated by interpolation shall be rounded to the nearest 1/100th of 1%, with any figure of 1/200% or above being rounded upward. If weekly average yields for United States Treasury Notes are not available in the H.15 Statistical Release or otherwise, then the Treasury Yield shall be calculated by interpolation of comparable rates selected by the Independent Investment Banker.

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

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

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of this series at the time Outstanding, on behalf of the Holders of all Securities of this series, and specified percentages in principal amounts of all Securities at the time Outstanding, on behalf of the holders of all Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

The Indenture contains provisions for the legal defeasance at any time of the entire indebtedness of the Company on this Security upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Security. Upon compliance with such provisions, the Company shall be deemed to have paid and discharged the entire indebtedness on this Security and the Company's obligation to pay the principal of (and premium, if any) and interest on this Security shall cease, terminate and be completely discharged.

The Indenture provides that no Holder of any Securities of any series may enforce any remedy under the Indenture except in the case of refusal or neglect of the Trustee to act after notice of default and request by the Holders of 25% in principal amount of Outstanding Securities in the series for which a remedy is sought to be enforced and the offer to the Trustee of reasonable indemnity.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall, without the consent of the Holder, alter or impair the right of the Holder, which is absolute and unconditional, to receive payment of principal of (and premium, if any) and interest on this Security at the times, place and rate, and in the coin or currency herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
