         any Additional Amounts with respect to the Securities of the series
         shall be payable;

         or any Additional Amounts with respect to the Securities of the series
         are to be payable, at the election of the Company or a Holder thereof,
         in a currency or currencies (including composite currencies) other than

         Maturity thereof pursuant to Section 6.02;

                  (17)     any restrictions or other provisions with respect to
         the transfer or exchange of Securities of the series, which may amend,
         supplement, modify or supersede those contained in this Article II;

                  (18)     if the Securities of the series are to be convertible
         into or exchangeable for capital stock, other debt securities
         (including Securities), warrants, other equity securities or any other
         securities or property of the Company or any other Person, at the
         option of the Company or the Holder or upon the occurrence of any
         condition or event, the terms and conditions for such conversion or
         exchange;

                  (19)     if the Securities of the series are to be entitled to
         the benefit of Section 4.04(b) (and accordingly constitute Rule 144A
         Securities), that fact; and

                  (20)     any other terms of the series (which terms shall not
         be prohibited by the provisions of this Indenture).

                  All Securities of any one series shall be substantially
identical except as to denomination and except as may otherwise be provided in
or pursuant to the Board Resolution referred to above and (subject to Section
2.03) set forth, or determined in the manner provided, in the Officers'
Certificate or Company Order referred to above or in any such indenture
supplemental hereto.

                  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 set forth in an Officers'
Certificate or 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 or Company Order setting forth the terms of the series.

         SECTION 2.02 Denominations.

                  The Securities of each series shall be issuable in such
denominations as shall be specified as contemplated by Section 2.01. In the
absence of any such provisions with respect to the Securities of any series, the
Securities of such series denominated in Dollars shall be issuable in
denominations of $1,000 and any integral multiples thereof.

         SECTION 2.03 Forms Generally.

                  The Securities of each series shall be in fully registered
form and in substantially such form or forms (including temporary or permanent
global form) established by or pursuant to a Board Resolution or in one or more
indentures supplemental hereto. The Securities may have notations, legends or
endorsements required by law, securities exchange rule, the Company's
certificate of incorporation, bylaws or other similar governing documents,
agreements to which the Company is subject, if any, or usage (provided that any
such notation, legend or endorsement is in a form acceptable to the Company). A
copy of the Board Resolution establishing the form of Securities of any series
shall be delivered to the Trustee at or prior to the delivery of the Company
Order contemplated by Section 2.04 for the authentication and delivery of such
Securities.

                  The definitive Securities of each series 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.

                  The Trustee's certificate of authentication 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.

                                                 JPMORGAN CHASE BANK, as Trustee

                                                 By: ___________________________
                                                         Authorized Officer".

         SECTION 2.04 Execution, Authentication, Delivery and Dating.

                  Two Officers of the Company shall sign the Securities on
behalf of the Company by manual or facsimile signature. If an Officer of the
Company whose signature is on a Security no longer holds that office at the time
the Security is authenticated, the Security shall be valid nevertheless.

                  A Security shall not be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose until authenticated by the
manual signature of an authorized signatory of the Trustee, which signature
shall be conclusive evidence that the Security has been authenticated under this
Indenture. Notwithstanding the foregoing, if any Security has been authenticated
and delivered hereunder but never issued and sold by the Company, and the
Company delivers such Security to the Trustee for cancellation as provided in
Section 2.13 together with a written statement (which need not comply with
Section 10.05 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.

                  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, and the Trustee shall
authenticate and deliver such Securities for original issue upon a Company Order
for the authentication and delivery of such Securities or pursuant to such
procedures acceptable to the Trustee as may be specified from time to time by
Company Order. Such order shall specify the amount of the Securities to be
authenticated, the date on which the original issue of Securities is to be
authenticated, the name or names of the initial Holder or Holders and any other
terms of the Securities of such series not otherwise determined. If provided for
in such procedures, such Company Order may authorize (1) authentication and
delivery of Securities of such series for original issue from time to time, with
certain terms (including, without limitation, the Stated Maturity dates or
dates, original issue date or dates and interest rate or rates) that differ from
Security to Security and (2) may authorize authentication and delivery pursuant
to oral or electronic instructions from the Company or its duly authorized
agent, which instructions shall be promptly confirmed in writing.

                  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
Section 2.01, 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 Company Order referred
to above and the other documents required by Section 10.04), and (subject to
Section 7.01) shall be fully protected in relying upon,

                                      -11-

<PAGE>

                  (a)      an Officers 'Certificate setting forth the Board
         Resolution and, if applicable, an appropriate record of any action
         taken pursuant thereto, as contemplated by the last paragraph of
         Section 2.01; and

                  (b)      an Opinion of Counsel to the effect that:

                           (i)      if the form of such Securities has been
                  established by or pursuant to Board Resolution, as is
                  permitted by Section 2.01, that such form has been established
                  in conformity with the provisions of this Indenture;

                           (ii)     if the terms of such Securities have been
                  established by or pursuant to Board Resolution, as is
                  permitted by Section 2.01, that such terms have been
                  established in conformity with the provisions of this
                  Indenture; and

                           (iii)    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 valid and binding obligations of
                  the Company, enforceable against the Company in accordance
                  with their terms, except as the enforceability thereof may be
                  limited by applicable bankruptcy, insolvency, reorganization,
                  moratorium, fraudulent conveyance or other similar laws in
                  effect from time to time affecting the rights of creditors
                  generally, and the application of general principles of equity
                  (regardless of whether such enforceability is considered in a
                  proceeding in equity or at law).

                  If all the Securities of any series are not to be issued at
one time, it shall not be necessary to deliver an Officers' Certificate and
Opinion of Counsel at the time of issuance of each such Security, but such
Officers' Certificate and Opinion of Counsel shall be delivered at or before the
time of issuance of the first Security of the series to be issued.

                  The Trustee shall not be required to authenticate such
Securities if the issuance of such Securities pursuant to this Indenture would
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.

                  The Trustee may appoint an authenticating agent acceptable to
the Company to authenticate Securities. Unless limited by the terms of such
appointment, an authenticating agent may authenticate Securities whenever the
Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the
same rights as an Agent to deal with the Company or an Affiliate of the Company.

                  Each Security shall be dated the date of its authentication.

         SECTION 2.05 Registrar and Paying Agent.

                  The Company shall maintain an office or agency for each series
of Securities where Securities of such series may be presented for registration
of transfer or exchange ("Registrar") and an office or agency where Securities
of such series may be presented for payment ("Paying Agent"). The Registrar
shall keep a register of the Securities of such series

                                      -12-

<PAGE>

and of their transfer and exchange. The Company may appoint one or more
co-registrars and one or more additional paying agents. The term "Registrar"
includes any co-registrar and the term "Paying Agent" includes any additional
paying agent.

                  The Company shall enter into an appropriate agency agreement
with any Registrar or Paying Agent not a party to this Indenture. The agreement
shall implement the provisions of this Indenture that relate to such Agent. The
Company shall notify the Trustee of the name and address of any Agent not a
party to this Indenture. The Company may change any Paying Agent or Registrar
without notice to any Holder. If the Company fails to appoint or maintain
another entity as Registrar or Paying Agent, the Trustee shall act as such. The
Company or any Subsidiary may act as Paying Agent or Registrar.

                  The Company initially appoints the Trustee as Registrar and
Paying Agent.

         SECTION 2.06 Paying Agent to Hold Money in Trust.

                  The Company shall require each Paying Agent other than the
Trustee to agree in writing that the Paying Agent will hold in trust for the
benefit of Holders or the Trustee all money held by the Paying Agent for the
payment of principal of, premium, if any, or interest on or any Additional
Amounts with respect to Securities and will notify the Trustee of any default by
the Company in making any such payment. While any such default continues, the
Trustee may require a Paying Agent to pay all money held by it to the Trustee
and to account for any funds disbursed. The Company at any time may require a
Paying Agent to pay all money held by it to the Trustee and to account for any
funds disbursed. Upon payment over to the Trustee and upon accounting for any
funds disbursed, the Paying Agent (if other than the Company or a Subsidiary)
shall have no further liability for the money. If the Company or a Subsidiary
acts as Paying Agent, it shall segregate and hold in a separate trust fund for
the benefit of the Holders all money held by it as Paying Agent. Each Paying
Agent shall otherwise comply with TIA Section 317(b).

         SECTION 2.07 Holder Lists.

                  The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and
addresses of Holders and shall otherwise comply with TIA Section 312(a). If the
Trustee is not the Registrar with respect to a series of Securities, the Company
shall furnish to the Trustee at least five Business Days before each Interest
Payment Date with respect to such series of Securities, and at such other times
as the Trustee may request in writing, a list in such form and as of such date
as the Trustee may reasonably require of the names and addresses of Holders of
such series, and the Company shall otherwise comply with TIA Section 312(a).

         SECTION 2.08 Transfer and Exchange.

                  Except as set forth in Section 2.17 or as may be provided
pursuant to Section 2.01:

                  When Securities of any series are presented to the Registrar
with the request to register the transfer of such Securities or to exchange such
Securities for an equal principal

                                      -13-

<PAGE>

amount of Securities of the same series of like tenor and of other authorized
denominations, the Registrar shall register the transfer or make the exchange as
requested if its requirements and the requirements of this Indenture for such
transactions are met; provided, however, that the Securities presented or
surrendered for registration of transfer or exchange shall be duly endorsed or
accompanied by a written instruction of transfer in form reasonably satisfactory
to the Registrar duly executed by the Holder thereof or by his attorney, duly
authorized in writing, on which instruction the Registrar can rely.

                  To permit registrations of transfers and exchanges, the
Company shall execute and the Trustee shall authenticate Securities at the
Registrar's written request and submission of the Securities or Global
Securities. No service charge shall be made to a Holder for any registration of
transfer or exchange (except as otherwise expressly permitted herein), but the
Company may require payment of a sum sufficient to cover any transfer tax or
similar governmental charge payable in connection therewith (other than such
transfer tax or similar governmental charge payable upon exchanges pursuant to
Section 2.12, 3.07 or 9.05). The Trustee shall authenticate Securities in
accordance with the provisions of Section 2.04. Notwithstanding any other
provisions of this Indenture to the contrary, the Company shall not be required
to register the transfer or exchange of (a) any Security selected for redemption
in whole or in part pursuant to Article III, except the unredeemed portion of
any Security being redeemed in part or (b) any Security during the period
beginning 15 Business Days before the mailing of notice of any offer to
repurchase Securities of the series required pursuant to the terms thereof or of
redemption of Securities of a series to be redeemed and ending at the close of
business on the day of mailing.

         SECTION 2.09 Replacement Securities.

                  If any mutilated Security is surrendered to the Trustee, or if
the Holder of a Security claims that the Security has been destroyed, lost or
stolen and the Trustee receives evidence to their satisfaction of the
destruction, loss or theft of such Security, the Company shall issue and the
Trustee shall authenticate a replacement Security of the same series if the
Trustee's requirements are met. If 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. If
required by the Trustee or the Company, such Holder must furnish an indemnity
bond that is sufficient in the judgment of the Trustee and the Company to
protect the Company, the Trustee, any Agent or any authenticating agent from any
loss that any of them may suffer if a Security is replaced. The Company and the
Trustee may charge a Holder for their expenses in replacing a Security.

                  Every replacement Security is an additional obligation of the
Company.

         SECTION 2.10 Outstanding Securities.

                  The Securities outstanding at any time are all the Securities
authenticated by the Trustee except for those canceled by it, those delivered to
it for cancellation, those reductions in the interest in a Global Security
effected by the Trustee hereunder and those described in this Section 2.10 as
not outstanding.

                                      -14-

<PAGE>

                  If a Security is replaced pursuant to Section 2.09, it ceases
to be outstanding unless the Company and the Trustee receive proof satisfactory
to them that the replaced Security is held by a bona fide purchaser.

                  If the principal amount of any Security is considered paid
under Section 4.01, it ceases to be outstanding and interest on it ceases to
accrue.

                  A Security does not cease to be outstanding because the
Company or an Affiliate of the Company holds the Security.

         SECTION 2.11 Original Issue Discount, Foreign-Currency Denominated and
                      Treasury Securities.

                  In determining whether the Holders of the required principal
amount of Securities have concurred in any direction, amendment, supplement,
waiver or consent, (a) the principal amount of an Original Issue Discount
Security shall be the principal amount thereof that would be due and payable as
of the date of such determination upon acceleration of the Stated Maturity
thereof pursuant to Section 6.02, (b) the principal amount of a Security
denominated in a foreign currency shall be the Dollar 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, as such rate is certified for customs
purposes by the Federal Reserve Bank of New York (the "Exchange Rate") on the
date of original issuance of such Security, of the principal amount (or, in the
case of an Original Issue Discount Security, the Dollar equivalent, as
determined by the Company by reference to the Exchange Rate on the date of
original issuance of such Security, of the amount determined as provided in (a)
above), of such Security and (c) Securities owned by the Company or any other
obligor upon the Securities or any Affiliate of the Company or of such other
obligor shall be disregarded, except that, for the purpose of determining
whether the Trustee shall be protected in relying upon any such direction,
amendment, supplement, waiver or consent, only Securities that the Trustee
actually knows are so owned shall be so disregarded.

         SECTION 2.12 Temporary Securities.

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

         SECTION 2.13 Cancellation.

                  The Company at any time may deliver Securities to the Trustee
for cancellation. The Registrar and the Paying Agent shall forward to the
Trustee any Securities surrendered to them for registration of transfer,
exchange, payment or redemption or for credit against any sinking fund payment.
The Trustee shall cancel all Securities surrendered for registration of
transfer, exchange, payment, redemption, replacement or cancellation or for
credit against any sinking fund. Unless the Company shall direct in writing that
canceled Securities be returned to

                                      -15-

<PAGE>

it, after written notice to the Company all canceled Securities held by the
Trustee shall be disposed of in accordance with the usual disposal procedures of
the Trustee, and the Trustee shall maintain a record of their disposal. The
Company may not issue new Securities to replace Securities that have been paid
or that have been delivered to the Trustee for cancellation.

         SECTION 2.14 Payments; Defaulted Interest.

                  Unless otherwise provided as contemplated by Section 2.01,
interest (except defaulted interest) on any Security that is payable, and is
punctually paid or duly provided for, on any Interest Payment Date shall be paid
to the Person who is the registered Holder of that Security at the close of
business on the record date next preceding such Interest Payment Date, even if
such Security is canceled after such record date and on or before such Interest
Payment Date. The Holder must surrender a Security to a Paying Agent to collect
principal payments. Unless otherwise provided with respect to the Securities of
any series, the Company will pay the principal of, premium (if any) and interest
on and any Additional Amounts with respect to the Securities in Dollars. Such
amounts shall be payable at the offices of the Trustee or any Paying Agent,
provided that at the option of the Company, the Company may pay such amounts (1)
by wire transfer with respect to Global Securities or (2) by check payable in
such money mailed to a Holder's registered address with respect to any
Securities.

                  If the Company defaults in a payment of interest on the
Securities of any series, the Company shall pay the defaulted interest in any
lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities may be listed, and upon such notice as may be required
by such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this clause, such manner of payment shall be deemed
practicable by the Trustee, plus, to the extent lawful, interest on the
defaulted interest, in each case at the rate provided in the Securities of such
series and in Section 4.01. The Company may pay the defaulted interest to the
Persons who are Holders on a subsequent special record date. At least 15 days
before any special record date selected by the Company, the Company (or the
Trustee, in the name of and at the expense of the Company upon 20 days' prior
written notice from the Company setting forth such special record date and the
interest amount to be paid) shall mail to Holders a notice that states the
special record date, the related payment date and the amount of such interest to
be paid.

                  Subject to the foregoing provisions of this Section 2.14, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

         SECTION 2.15 Persons Deemed Owners.

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

         SECTION 2.16 Computation of Interest.

                  Except as otherwise specified as contemplated by Section 2.01
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 2.17 Global Securities; Book-Entry Provisions.

                  If Securities of a series are issuable in global form as a
Global Security, as contemplated by Section 2.01, then, notwithstanding clause
(10) of Section 2.01 and the provisions of Section 2.02, any such Global
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 or increased, as appropriate, to reflect exchanges, transfers or
redemptions. Any endorsement of a Global Security to reflect the amount, or any
increase or decrease in the amount, of outstanding Securities represented
thereby shall be made by the Trustee (i) 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 2.04 or (ii)
otherwise in accordance with written instructions or such other written form of
instructions as is customary for the Depositary for such Security, from such
Depositary or its nominee on behalf of any Person having a beneficial interest
in such Global Security. Subject to the provisions of Section 2.04 and, if
applicable, Section 2.12, 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. With
respect to the Securities of any series that are represented by a Global
Security, the Company authorizes the execution and delivery by the Trustee of a
letter of representations or other similar agreement or instrument in the form
customarily provided for by the Depositary appointed with respect to such Global
Security. Any Global Security may be deposited with the Depositary or its
nominee, or may remain in the custody of the Trustee or the Security Custodian.
If a Company Order 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
10.05 and need not be accompanied by an Opinion of Counsel.

                  Members of, or participants in, the Depositary ("Agent
Members") shall have no rights under this Indenture with respect to any Global
Security held on their behalf by the Depositary, or the Trustee or the Security
Custodian as its custodian, or under such Global Security, and the Depositary
may be treated by the Company, the Trustee or the Security Custodian and any
agent of the Company, the Trustee or the Security Custodian as the absolute
owner of such Global Security for all purposes whatsoever. Notwithstanding the
foregoing, (i) the registered holder of a Global Security of a series may grant
proxies and otherwise authorize any Person, including Agent Members and Persons
that may hold interests through Agent Members, to take any action that a Holder
of Securities of such series is entitled to take under this Indenture or the
Securities of such series and (ii) nothing herein shall prevent the Company, the
Trustee or the Security Custodian, or any agent of the Company, the Trustee or
the Security Custodian, from giving effect to any written certification, proxy
or other authorization furnished by the Depositary or shall impair, as between
the Depositary and its Agent Members, the

                                      -17-

<PAGE>

operation of customary practices governing the exercise of the rights of a
beneficial owner of any Security.

                  Notwithstanding Section 2.08, and except as otherwise provided
pursuant to Section 2.01, Transfers of a Global Security shall be limited to
transfers of such Global Security in whole, but not in part, to the Depositary,
its successors or their respective nominees. Interests of beneficial owners in a
Global Security may be transferred in accordance with the rules and procedures
of the Depositary. Securities shall be transferred to all beneficial owners in
exchange for their beneficial interests in a Global Security if, and only if,
either (1) the Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for the Global Security and a successor Depositary is not
appointed by the Company within 90 days of such notice, (2) an Event of Default
has occurred with respect to such series and is continuing and the Registrar has
received a request from the Depositary to issue Securities in lieu of all or a
portion of the Global Security (in which case the Company shall deliver
Securities within 30 days of such request) or (3) the Company determines not to
have the Securities represented by a Global Security.

                  In connection with any transfer of a portion of the beneficial
interests in a Global Security to beneficial owners pursuant to this Section
2.17, the Registrar shall reflect on its books and records the date and a
decrease in the principal amount of the Global Security in an amount equal to
the principal amount of the beneficial interests in the Global Security to be
transferred, and the Company shall execute, and the Trustee upon receipt of a
Company Order for the authentication and delivery of Securities shall
authenticate and deliver, one or more Securities of the same series of like
tenor and amount.

                  In connection with the transfer of all the beneficial
interests in a Global Security to beneficial owners pursuant to this Section
2.17, the Global Security shall be deemed to be surrendered to the Trustee for
cancellation, and the Company shall execute, and the Trustee shall authenticate
and deliver, to each beneficial owner identified by the Depositary in exchange
for its beneficial interests in the Global Security, an equal aggregate
principal amount of Securities of authorized denominations.

                  Neither the Company nor the Trustee will have any
responsibility or liability for any aspect of the records relating to, or
payments made on account of, Securities by the Depositary, or for maintaining,
supervising or reviewing any records of the Depositary relating to such
Securities. Neither the Company nor the Trustee shall be liable for any delay by
the related Global Security Holder or the Depositary in identifying the
beneficial owners, and each such Person may conclusively rely on, and shall be
protected in relying on, instructions from such Global Security Holder or the
Depositary for all purposes (including with respect to the registration and
delivery, and the respective principal amounts, of the Securities to be issued).

                  The provisions of the last sentence of the third paragraph of
Section 2.04 shall apply to any Global Security if such Global Security was
never issued and sold by the Company and the Company delivers to the Trustee the
Global Security together with written instructions (which need not comply with
Section 10.05 and need not be accompanied by an Opinion of Counsel) with regard
to the cancellation or reduction in the principal amount of Securities
represented thereby, together with the written statement contemplated by the
last sentence of the third paragraph of Section 2.04.

                  Notwithstanding the provisions of Sections 2.03 and 2.14,
unless otherwise specified as contemplated by Section 2.01, payment of principal
of, premium (if any) and interest on and any Additional Amounts with respect to
any Global Security shall be made to the Person or Persons specified therein.

                                  ARTICLE III
                                  REDEMPTION

         SECTION 3.01 Applicability of Article.

                  Securities of any series that are redeemable before their
Stated Maturity shall be redeemable in accordance with their terms and (except
as otherwise specified as contemplated by Section 2.01 for Securities of any
series) in accordance with this Article III.

         SECTION 3.02 Notice to the Trustee.

                  If the Company elects to redeem Securities of any series
pursuant to this Indenture, it shall notify the Trustee of the Redemption Date
and the principal amount of Securities of such series to be redeemed. The
Company shall so notify the Trustee at least 45 days before the Redemption Date
(unless a shorter notice shall be satisfactory to the Trustee) by delivering to
the Trustee an Officers' Certificate stating that such redemption will comply
with the provisions of this Indenture and of the Securities of such series. Any
such notice may be canceled at any time prior to the mailing of such notice of
such redemption to any Holder and shall thereupon be void and of no effect.

         SECTION 3.03 Selection of Securities To Be Redeemed.

                  If less than all the Securities of any series are to be
redeemed (unless all of the Securities of such series of a specified tenor are
to be redeemed), the particular Securities to be redeemed shall be selected not
more than 60 days prior to the Redemption Date by the Trustee from the
outstanding Securities of such series (and tenor) not previously called for
redemption, pro rata, by lot or by such other method as the Trustee shall deem
fair and appropriate and that may provide for the selection for redemption of
portions (equal to the minimum authorized denomination for Securities of that
series or any integral multiple thereof) of the principal amount of Securities
of such series of a denomination larger than the minimum authorized denomination
for Securities of that series or of the principal amount of Global Securities of
such series.

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

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

                                      -19-

<PAGE>

         SECTION 3.04 Notice of Redemption.

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

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

                  (1)      the Redemption Date;

                  (2)      the Redemption Price, and accrued interest, if any;

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

                  (4)      if any Security is to be redeemed in part, the
         portion of the principal amount thereof to be redeemed and that on and
         after the Redemption Date, upon surrender for cancellation of such
         Security to the Paying Agent, a new Security or Securities in the
         aggregate principal amount equal to the unredeemed portion thereof will
         be issued without charge to the Holder;

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

                  (6)      that the redemption is for a sinking or analogous
         fund, if such is the case; and

                  (7)      the CUSIP number, if any, relating to such
         Securities.

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

         SECTION 3.05 Effect of Notice of Redemption.

                  Once notice of redemption is mailed, Securities called for
redemption become due and payable on the Redemption Date and at the Redemption
Price. Upon surrender to the Paying Agent, such Securities called for redemption
shall be paid at the Redemption Price, but interest installments whose maturity
is on or prior to such Redemption Date will be payable on the relevant Interest
Payment Dates to the Holders of record at the close of business on the relevant
record dates specified pursuant to Section 2.01.

         SECTION 3.06 Deposit of Redemption Price.

                  On or prior to any Redemption Date, the Company shall deposit
with the Trustee or the Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 2.06) an amount
of money in same day funds sufficient to pay the Redemption Price of, and
(except if the Redemption Date shall be an Interest Payment Date) accrued
interest on and any Additional Amounts with respect to, the Securities or
portions thereof which are to be redeemed on that date, other than Securities or
portions thereof called for redemption on that date which have been delivered by
the Company to the Trustee for cancellation.

                  If the Company complies with the preceding paragraph, then,
unless the Company defaults in the payment of such Redemption Price, interest on
the Securities to be redeemed will cease to accrue on and after the applicable
Redemption Date, whether or not such Securities are presented for payment, and
the Holders of such Securities shall have no further rights with respect to such
Securities except for the right to receive the Redemption Price upon surrender
of such Securities. If any Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal, premium, if any, any
Additional Amounts, and, to the extent lawful, accrued interest thereon shall,
until paid, bear interest from the Redemption Date at the rate specified
pursuant to Section 2.01 or provided in the Securities or, in the case of
Original Issue Discount Securities, such Securities' yield to maturity.

         SECTION 3.07 Securities Redeemed or Purchased in Part.

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

         SECTION 3.08 Purchase of Securities.

                  Unless otherwise specified as contemplated by Section 2.01,
the Company and any Affiliate of the Company may at any time purchase or
otherwise acquire Securities in the open market or by private agreement. Any
such acquisition shall not operate as or be deemed for any purpose to be a
redemption of the indebtedness represented by such Securities. Any Securities
purchased or acquired by the Company may be delivered to the Trustee and, upon
such delivery, the indebtedness represented thereby shall be deemed to be
satisfied. Section 2.13 shall apply to all Securities so delivered.

         SECTION 3.09 Mandatory and Optional Sinking Funds.

                  The minimum amount of any sinking fund payment provided for by
the terms of Securities of any series is herein referred to as a "mandatory
sinking fund payment," and any payment in excess of such minimum amount provided
for by the terms of Securities of any series is herein referred to as an
"optional sinking fund payment." Unless otherwise provided by the terms of
Securities of any series, the cash amount of any sinking fund payment may be
subject to

                                      -21-

<PAGE>

reduction as provided in Section 3.10. Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series and by this Article III.

         SECTION 3.10 Satisfaction of Sinking Fund Payments with Securities.

                  The Company may deliver outstanding Securities of a series
(other than any previously called for redemption) and may apply as a credit
Securities of a series that have been redeemed either at the election of the
Company pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of such series required to be made
pursuant to the terms of such series of Securities; provided that such
Securities have not been previously so credited. Such Securities shall be
received and credited for such purpose by the Trustee at the Redemption Price
specified in such Securities for redemption through operation of the sinking
fund and the amount of such sinking fund payment shall be reduced accordingly.

         SECTION 3.11 Redemption of Securities for Sinking Fund.

                  Not less than 45 days prior (unless a shorter period shall be
satisfactory to the Trustee) to each sinking fund payment date for any series of
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivery of or by crediting Securities of that series pursuant to
Section 3.10 and will also deliver or cause to be delivered to the Trustee any
Securities to be so delivered. Failure of the Company to timely deliver or cause
to be delivered such Officers' Certificate and Securities specified in this
paragraph, if any, shall not constitute a default but shall constitute the
election of the Company (i) that the mandatory sinking fund payment for such
series due on the next succeeding sinking fund payment date shall be paid
entirely in cash without the option to deliver or credit Securities of such
series in respect thereof and (ii) that the Company will make no optional
sinking fund payment with respect to such series as provided in this Section.

                  If the sinking fund payment or payments (mandatory or optional
or both) to be made in cash on the next succeeding sinking fund payment date
plus any unused balance of any preceding sinking fund payments made in cash
shall exceed $100,000 (or the Dollar equivalent thereof based on the applicable
Exchange Rate on the date of original issue of the applicable Securities) or a
lesser sum if the Company shall so request with respect to the Securities of any
particular series, such cash shall be applied on the next succeeding sinking
fund payment date to the redemption of Securities of such series at the sinking
fund redemption price together with accrued interest to the date fixed for
redemption. If such amount shall be $100,000 (or the Dollar equivalent thereof
as aforesaid) or less and the Company makes no such request then it shall be
carried over until a sum in excess of $100,000 (or the Dollar equivalent thereof
as aforesaid) is available. Not less than 30 days before each such sinking fund
payment date, the Trustee shall select the Securities to be redeemed upon such
sinking fund payment date in the manner specified in Section 3.03 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Company in the manner provided in Section 3.04. Such notice

                                      -22-

<PAGE>

having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in Sections 3.05, 3.06 and 3.07.

                                   ARTICLE IV
                                   COVENANTS

         SECTION 4.01 Payment of Securities.

                  The Company shall pay the principal of, premium (if any) and
interest on and any Additional Amounts with respect to the Securities of each
series on the dates and in the manner provided in the Securities of such series
and in this Indenture. Principal, premium, interest and any Additional Amounts
shall be considered paid on the date due if the Paying Agent, other than the
Company or a Subsidiary, holds on that date money deposited by the Company
designated for and sufficient to pay all principal, premium, interest and any
Additional Amounts then due and the Paying Agent is not prohibited from paying
such money to the Holder on such date pursuant to the terms of this Indenture.

                  The Company shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue principal and
premium (if any), at a rate equal to the then applicable interest rate on the
Securities to the extent lawful; and it shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest and any Additional Amount (without regard to any
applicable grace period) at the same rate to the extent lawful.

         SECTION 4.02 Maintenance of Office or Agency.

                  The Company will maintain in each Place of Payment for any
series of Securities an office or agency (which may be an office of the Trustee,
the Registrar or the Paying Agent) where Securities of that series may be
presented for registration of transfer or exchange, where Securities of that
series may be presented for payment and where notices and demands to or upon the
Company in respect of the Securities of that series and this Indenture may be
served. Unless otherwise designated by the Company by written notice to the
Trustee, such office or agency shall be the office of the Trustee in Dallas,
Texas, which on the date hereof is located at 2001 Bryan Street, 9th Floor,
Dallas, Texas 75201. 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. The Company will give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such
other office or agency.

<PAGE>

                  Notwithstanding anything to the contrary contained in this
Indenture, the Company may, to the extent it is required to do so by law, deduct
or withhold income or other similar taxes imposed by the United State of America
from principal, premium (if any), or interest payments hereunder.

         SECTION 4.03 Money for Security Payments to Be Held in Trust.

                  If the Company shall at any time act as its own Paying Agent,
it will, on or before each due date of the principal of (or Additional Amounts,
if any) or interest on any of the Securities, segregate and hold in trust for
the benefit of the Persons entitled thereto a sum sufficient to pay the
principal of (or Additional Amounts, 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 in writing of its action or
failure to so act.

                  Whenever the Company shall have one or more Paying Agents for
the Securities, it will, on or before each due date of the principal of (or
Additional Amounts, if any) or interest on any Securities, deposit with any
Paying Agent a sum in same day funds (or New York Clearing House funds if such
deposit is made prior to the date on which such deposit is required to be made)
that shall be available to the Trustee by 10:00 a.m. New York City time on such
due date sufficient to pay the principal (or Additional Amounts, if any) or
interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal, Additional Amounts or interest, and (unless
such Paying Agent is the Trustee) the Company will promptly notify the Trustee
in writing of such action or any failure to so act.

                  The Company will cause each Paying Agent (other than the
Trustee) to execute and deliver to the Trustee an instrument in which such
Paying Agent shall agree with the Trustee, subject to the provisions of this
Section 4.03, that such Paying Agent will:

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

                  (b)      give the Trustee prompt written notice of any default
         by the Company (or any other obligor upon the Securities) in the making
         of any payment of principal (and Additional Amounts, if any) or
         interest; and

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

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

                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of (or
Additional Amounts, if any) or interest on any Security and remaining unclaimed
for two years after such principal, Additional Amounts or interest has become
due and payable shall be paid to the Company on Company order, 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 to the
Company, shall at the expense of the Company cause to be published once, in a
leading daily newspaper (if practicable, The Wall Street Journal (Eastern
Edition)) printed in the English language and of general circulation in New York
City, notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication
nor shall it be later than two years after such principal (or Additional
Amounts, if any) or interest shall have become due and payable, any unclaimed
balance of such money then remaining will be repaid to the Company.

         SECTION 4.04 SEC Reports; Financial Statements.

                  (a)      The Company shall file with the Trustee, within 15
days after it files the same with the SEC, copies of the annual reports and the
information, documents and other reports (or copies of such portions of any of
the foregoing as the SEC may by rules and regulations prescribe) that the
Company is required to file with the SEC pursuant to Section 13 or 15(d) of the
Exchange Act. If this Indenture is qualified under the TIA, but not otherwise,
the Company shall also comply with the provisions of TIA Section 314(a).

                  (b)      If the Company is not subject to the requirements of
Section 13 or 15(d) of the Exchange Act, the Company shall furnish to all
Holders of Rule 144A Securities and prospective purchasers of Rule 144A
Securities designated by the Holders of Rule 144A Securities, promptly upon
their request, the information required to be delivered pursuant to Rule
144A(d)(4) promulgated under the Securities Act of 1933, as amended.

                  (c)      The Company intends to file the reports referred to
in clauses (a) and (b) of this Section 4.04 with the SEC in electronic form
pursuant to Regulation S-T of the SEC using the SEC's Electronic Data Gathering,
Analysis and Retrieval ("EDGAR") system. The Company shall notify the Trustee in
the manner prescribed herein of each such filing. The Trustee is hereby
authorized and directed to access the EDGAR system for purposes of retrieving
the reports so filed. Compliance with the foregoing shall constitute delivery by
the Company of such reports to the Trustee in compliance with the provisions of
TIA Section 314(a). The Trustee shall have no duty to search for or obtain any
electronic or other filings that the Company makes with the SEC, regardless of
whether such filings are periodic, supplemental or otherwise. Delivery of the
reports, information and documents to the Trustee pursuant to this Section 4.04
shall be solely for the purposes of compliance with this Section 4.04 and with
TIA Section 314(a). The Trustee's receipt of such reports, information and
documents shall not constitute notice to it of the content thereof or of any
matter determinable from the content thereof, including the Company's compliance
with any of its covenants hereunder, as to which the Trustee is entitled to rely
upon Officers' Certificates.

         SECTION 4.05 Compliance Certificate.

                  (a)      The Company shall deliver to the Trustee, within 120
days after the end of each fiscal year of the Company, a statement signed by an
Officer of the Company, which need not constitute an Officers' Certificate,
complying with TIA Section 314(a)(4) and stating that in the course of
performance by the signing Officer of his duties as such Officer of the Company
he would normally obtain knowledge of the keeping, observing, performing and
fulfilling by the Company of its obligations under this Indenture, and further
stating that to the best of his knowledge the Company has kept, observed,
performed and fulfilled each and every covenant contained in this Indenture and
is not in default in the performance or observance of any of the terms,
provisions and conditions hereof (or, if a Default or Event of Default shall
have occurred, describing all such Defaults or Events of Default of which such
Officer may have knowledge and what action the Company is taking or proposes to
take with respect thereto).

                  (b)      The Company shall, so long as Securities of any
series are outstanding, deliver to the Trustee, forthwith upon any Officer of
the Company becoming aware of any Default or Event of Default under this
Indenture, an Officers' Certificate specifying such Default or Event of Default
and what action the Company is taking or proposes to take with respect thereto.

         SECTION 4.06 Corporate Existence.

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

         SECTION 4.07 Payment of Taxes and Other Claims.

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

         SECTION 4.08 Waiver of Stay, Extension or Usury Laws.

                  The Company covenants (to the extent that it may lawfully do
so) that it will not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay or extension law
or any usury law or other law that would prohibit or

                                      -26-

<PAGE>

forgive the Company from paying all or any portion of the principal of or
interest on the Securities as contemplated herein, wherever enacted, now or at
any time hereafter in force, or which may affect the covenants or the
performance of this Indenture; and (to the extent that it may lawfully do so)
the Company 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 4.09 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 4.09 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 4.09 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.

         SECTION 4.10 Restriction on Creation of Secured Debt.

                  So long as any of the Securities are outstanding, the Company
shall not at any time create, incur or assume, and shall not cause, suffer or
permit a Restricted Subsidiary to create, incur or assume, any Secured Debt
without making effective provision (and the Company covenants that in such case
it will make or cause to be made such effective provision) whereby the
Securities then outstanding and any other indebtedness of the Company or such
Restricted Subsidiary then entitled thereto, subject to applicable priorities of
payment, shall be secured by such mortgage, security interest, pledge, lien or
encumbrance equally and ratably with any and all other obligations and
indebtedness thereby secured, so long as any such other obligations and
indebtedness shall be so secured; provided, however, that the foregoing
covenants shall not be applicable to the following:

                           (a)      (i) Any mortgage, security interest, pledge,
         lien or encumbrance on any property hereafter acquired (including
         acquisition through merger or consolidation) or constructed by the
         Company or a Restricted Subsidiary and created contemporaneously with,
         or within twelve months after, such acquisition or the completion of
         construction to secure or provide for the payment of all or any part of
         the purchase price of such property or the cost of construction
         thereof, as the case may be; or (ii) any mortgage on property
         (including any unimproved portion of partially improved property) of
         the Company or a Restricted Subsidiary created within twelve months of
         completion of construction of a new plant or plants on such property to
         secure all or part of the cost of such construction if, in the opinion
         of the Board of Directors, such property or such portion thereof was
         prior to such construction substantially unimproved for the use
         intended by the Company; or (iii) the acquisition of property subject
         to any mortgage,

                                      -27-

<PAGE>

         security interest, pledge, lien or encumbrance upon such property
         existing at the time of acquisition thereof, whether or not assumed by
         the Company or such Restricted Subsidiary; or (iv) any mortgage,
         security interest, pledge, lien or encumbrance existing on the property
         or on the outstanding shares or indebtedness of a corporation at the
         time such corporation shall become a Restricted Subsidiary; or (v) any
         mortgage, security interest, pledge, lien or encumbrance on property of
         a corporation existing at the time such corporation is merged into or
         consolidated with the Company or a Restricted Subsidiary or at the time
         of a sale, lease or other disposition of the properties of a
         corporation or firm as an entirety or substantially as an entirety to
         the Company or a Restricted Subsidiary; or

                           (b)      Mortgages on property of the Company or a
         Restricted Subsidiary in favor of the United States of America or any
         State thereof or any foreign government, or any department, agency or
         instrumentality or political subdivision of any thereof, to secure
         partial, progress, advance or other payments pursuant to any contract
         or statute or to secure any indebtedness incurred for the purpose of
         financing all or any part of the purchase price or the cost of
         construction of the property subject to such mortgages; or

                           (c)      Any extension, renewal or replacement (or
         successive extensions, renewals or replacements) in whole or in part of
         any mortgage, security interest pledge, lien or encumbrance referred to
         in the foregoing subparagraphs (a) and (b); provided, however, that the
         principal amount of Secured Debt secured thereby shall not exceed the
         principal amount outstanding at the time of such extension, renewal or
         replacement, and that such extension, renewal or replacement shall be
         limited to the property which secured the mortgage, security interest,
         pledge, lien or encumbrance so extended, renewed or replaced and
         additions to such property.

                  Notwithstanding the foregoing provisions of this Section 4.10,
the Company and any one or more Restricted Subsidiaries may create, incur,
assume or guarantee Secured Debt which would otherwise be subject to the
foregoing restrictions in an aggregate amount which, together with all other
Secured Debt of the Company and its Restricted Subsidiaries which would
otherwise be subject to the foregoing restrictions (not including Secured Debt
permitted to be secured under subparagraphs (a) through (c) above) and the
aggregate value of the Sale and Leaseback Transactions (as defined in Section
4.11) in existence at such time (not including Sale and Leaseback Transactions
the proceeds of which have been or will be applied in accordance with clause (b)
of Section 4.11), does not at the time exceed five percent of Consolidated Net
Tangible Assets.

         SECTION 4.11 Limitation on Sale and Leaseback Transactions.

                  The Company will not, and will not permit any Restricted
Subsidiary to, sell or transfer (except to the Company or to one or more
Restricted Subsidiaries, or both) any Principal Property owned by it and which
has been in full operation for more than 120 days prior to such sale or transfer
with the intention (i) of taking back a lease on such property, except a lease
for a temporary period (not exceeding 36 months), and (ii) that the use by the
Company or such Restricted Subsidiary of such property will be discontinued on
or before the expiration of the term of such lease (any such transaction being
herein referred to as a "Sale and Leaseback

                                      -28-

<PAGE>

Transaction"), unless (a) the Company or such Restricted Subsidiary would be
entitled, pursuant to the provisions of Section 4.10, to incur Secured Debt
equal in amount to the amount realized or to be realized upon such sale or
transfer secured by a mortgage on the property to be leased without equally and
ratably securing the Securities, or (b) the Company or a Restricted Subsidiary
shall apply an amount equal to the value of the property so leased to the
retirement (other than any mandatory retirement), within 120 days of the
effective date of any such arrangement, of indebtedness for money borrowed by
the Company or any Restricted Subsidiary (other than such indebtedness owned by
the Company or any Restricted Subsidiary) which was recorded as funded debt as
of the date of its creation and which, in the case of such indebtedness of the
Company, is not subordinate and junior in right of payment to the prior payment
of the Securities; provided, however, that the amount to be so applied to the
retirement of such indebtedness shall be reduced by (i) the aggregate principal
amount of any Securities delivered within 120 days of the effective date of any
such arrangement to the Trustee for retirement and cancellation, and (ii) the
aggregate principal amount of such indebtedness (other than the Securities)
retired by the Company or a Restricted Subsidiary within 120 days of the
effective date of any such arrangement.

                  The term "value" shall mean, with respect to a Sale and
Leaseback Transaction, as of any particular time, the amount equal to the
greater of (i) the net proceeds of the sale of the property leased pursuant to
such Sale and Leaseback Transaction, or (ii) the fair value of such property at
the time of entering into such Sale and Leaseback Transaction, as determined by
the Board of Directors, in either case divided first by the number of full years
of the term of the lease and then multiplied by the number of full years of such
term remaining at the time of determination, without regard to any renewal or
extension options contained in the lease.

         SECTION 4.12 Further Instruments and Acts.

                  Upon request of the Trustee, the Company will execute and
deliver such further instruments and do such further acts as may be reasonably
necessary or proper to carry out more effectively the purpose of this Indenture.

                                   SUCCESSORS

         SECTION 5.01 Merger and Consolidation.

                  The Company shall not, in any transaction or series of
transactions, consolidate with or merge with or into any Person, or sell, lease,
convey, transfer or otherwise dispose of all or substantially all of its assets
to any Person, unless:

                  (1)      either (a) the Company shall be the continuing Person
         or (b) the Person (if other than the Company) formed by such
         consolidation or into which the Company is merged, or to which such
         sale, lease, conveyance, transfer or other disposition shall be made
         (collectively, the "Successor"), is organized and validly existing
         under the laws of the United States, any political subdivision thereof
         or any State thereof or the District of Columbia, and expressly assumes
         by supplemental indenture the due and punctual payment of the principal
         of, premium (if any) and interest on and any Additional

                                      -29-

<PAGE>

         Amounts with respect to all the Securities and the performance of the
         Company's covenants and obligations under this Indenture and the
         Securities;

                  (2)      immediately after giving effect to such transaction
         or series of transactions (and treating any Indebtedness that becomes
         an obligation of the Successor or any Restricted Subsidiary of the
         Successor as a result of such transaction as having been incurred by
         the Successor or such Restricted Subsidiary at the time of such
         transaction), no Default or Event of Default shall have occurred and be
         continuing or would result therefrom; and

                  (3)      the Company delivers to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that the
         transaction and such supplemental indenture comply with this Indenture.

                  For purposes of this Section 5.01, the sale, lease,
conveyance, assignment, transfer, or other disposition of all or substantially
all of the properties and assets of one or more Subsidiaries of the Company,
which properties and assets, if held by the Company instead of such
Subsidiaries, would constitute all or substantially all of the properties and
assets of the Company on a consolidated basis, shall be deemed to be the
transfer of all or substantially all of the properties and assets of the
Company.

         SECTION 5.02 Securities to be Secured in Certain Events.

                  If, upon any such consolidation or merger, or upon any such
sale, conveyance or lease, or upon any acquisition by the Company by purchase or
otherwise of all or any part of the properties of any other corporation, any
Principal Property owned by the Company or a Restricted Subsidiary immediately
prior thereto would thereupon become subject to any mortgage, security interest,
pledge, lien or encumbrance, not permitted by Section 4.10 hereof, the Company,
prior to such consolidation, merger, sale, conveyance, lease or acquisition,
will by indenture supplemental hereto secure the due and punctual payment of the
principal of and interest, if any, on the Securities then outstanding (equally
and ratably with any other indebtedness of or guaranteed by the Company then
entitled thereto) by a direct lien on such Principal Property, together with any
other properties and assets of the Company or of any such Restricted Subsidiary,
whichever shall be the owner of any such Principal Property, which would
thereupon become subject to any such mortgage, security interest, pledge, lien
or encumbrance, prior to all liens other than any theretofore existing thereon.

         SECTION 5.03 Successor Person Substituted.

                  Upon any consolidation or merger of the Company or any sale,
lease, conveyance, transfer or other disposition of all or substantially all of
the assets of the Company in accordance with Section 5.01, the Successor formed
by such consolidation or into or with which the Company is merged or to which
such sale, lease, conveyance, transfer or other disposition is made shall
succeed to, and be substituted for, and may exercise every right and power of
the Company under this Indenture and the Securities with the same effect as if
such Successor had been named as the Company herein and the predecessor Company,
in the case of a sale,

                                      -30-

conveyance, transfer or other disposition, shall be released from all
obligations under this Indenture and the Securities.

                              DEFAULTS AND REMEDIES

         SECTION 6.01 Events of Default.

                  Unless either inapplicable to a particular series or
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, an "Event of Default," wherever used herein with
respect to Securities of any series, occurs if:

                  (1)      the Company defaults in the payment of interest on or
         any Additional Amounts with respect to any Security of that series when
         the same becomes due and payable and such default continues for a
         period of 30 days;

                  (2)      the Company defaults in the payment of (A) the
         principal of any Security of that series at its Stated Maturity or (B)
         premium (if any) on any Security of that series when the same becomes
         due and payable;

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

                  (4)      the Company fails to comply with any of its other
         covenants or agreements in, or provisions of, the Securities of such
         series or this Indenture (other than an agreement, covenant or
         provision that has expressly been included in this Indenture solely for
         the benefit of one or more series of Securities other than that series)
         which shall not have been remedied within the specified period after
         written notice, as specified in the last paragraph of this Section
         6.01;

                  (5)      the Company defaults in a scheduled payment at
         maturity, upon redemption or otherwise, in the aggregate principal
         amount of $125 million or more, after the expiration of any applicable
         grace period, of any Indebtedness or the acceleration of any
         Indebtedness of the Company in such aggregate principal amount, so that
         it becomes due and payable prior to the date on which it would
         otherwise have become due and payable and such payment default is not
         cured or such acceleration is not rescinded within 30 days after notice
         to the Company in accordance with the terms of the Indebtedness;

                  (6)      the Company pursuant to or within the meaning of any
         Bankruptcy Law:

                           (A)      commences a voluntary case,

                           (B)      consents to the entry of an order for relief
                  against it in an involuntary case,

                                      -31-

<PAGE>

                           (C)      consents to the appointment of a Bankruptcy
                  Custodian of it or for all or substantially all of its
                  property, or

                           (D)      makes a general assignment for the benefit
                  of its creditors;

                  (7)      a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that remains unstayed and in effect for
         90 days and that:

                           (A)      is for relief against the Company as debtor
                  in an involuntary case,

                           (B)      appoints a Bankruptcy Custodian of the
                  Company or a Bankruptcy Custodian for all or substantially all
                  of the property of the Company, or

                           (C)      orders the liquidation of the Company; or

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

                  The term "Bankruptcy Custodian" means any receiver, trustee,
assignee, liquidator or similar official under any Bankruptcy Law.

                  The Trustee shall not be deemed to know or have notice of any
Default or Event of Default unless a Trust Officer at the Corporate Trust Office
of the Trustee receives written notice at the Corporate Trust Office of the
Trustee of such Default or Event of Default with specific reference to such
Default or Event of Default.

                  When a Default is cured, it ceases to be a Default.

                  Notwithstanding the foregoing provisions of this Section 6.01,
if the principal of, premium (if any) or interest on or any 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 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 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 6.01, 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 in the manner provided in Section
10.02 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 10.02 to the Holders, setting forth the applicable Exchange
Rate and describing the calculation of such payments.

                                      -32-

<PAGE>

                  A Default under clause (4) or (7) of this Section 6.01 is not
an Event of Default until the Trustee notifies the Company, or the Holders of at
least 25% in principal amount of the then outstanding Securities of the series
affected by such Default (or, in the case of a Default under clause (4) of this
Section 6.01, if outstanding Securities of other series are affected by such
Default, then at least 25% in principal amount of the then outstanding
Securities so affected) notify the Company and the Trustee, of the Default, and
the Company fails to cure the Default within 60 days after receipt of the
notice. The notice must specify the Default, demand that it be remedied and
state that the notice is a "Notice of Default."

         SECTION 6.02 Acceleration.

                  If an Event of Default with respect to any Securities of any
series at the time outstanding (other than an Event of Default specified in
clause (6) or (7) of Section 6.01) occurs and is continuing, either the Trustee
by notice to the Company, or the Holders of at least 25% in principal amount of
the then outstanding Securities of the series affected by such Event of Default
(or, in the case of an Event of Default described in clause (4) of Section 6.01,
if outstanding Securities of other series are affected by such Event of Default,
then at least 25% in principal amount of the then outstanding Securities so
affected) by notice to the Company and the Trustee, may declare the principal of
(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) and
accrued and unpaid interest on all then outstanding Securities of such series or
of all series, as the case may be, to be due and payable. Upon any such
declaration, the amounts due and payable on the Securities shall be due and
payable immediately. If an Event of Default specified in clause (6) or (7) of
Section 6.01 hereof occurs, such amounts shall ipso facto become and be
immediately due and payable without any declaration, notice or other act on the
part of the Trustee or any Holder. The Holders of a majority in principal amount
of the then outstanding Securities of the series affected by such Event of
Default or all series, as the case may be, by written notice to the Trustee may
rescind an acceleration and its consequences (other than nonpayment of principal
of or premium or interest on or any Additional Amounts with respect to the
Securities) if the rescission would not conflict with any judgment or decree and
if all existing Events of Default with respect to Securities of that series (or
of all series, as the case may be) have been cured or waived, except nonpayment
of principal, premium, interest or any Additional Amounts that has become due
solely because of the acceleration.

         SECTION 6.03 Other Remedies.

                  If an Event of Default occurs and is continuing, the Trustee
may pursue any available remedy to collect the payment of principal of, or
premium, if any, or interest on the Securities or to enforce the performance of
any provision of the Securities or this Indenture.

                  The Trustee may maintain a proceeding even if it does not
possess any of the Securities or does not produce any of them in the proceeding.
A delay or omission by the Trustee or any Holder in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

         SECTION 6.04 Waiver of Defaults.

                  Subject to Sections 6.07 and 9.02, the Holders of a majority
in principal amount of the then outstanding Securities of any series or of all
series (acting as one class) by notice to the Trustee may waive an existing or
past Default or Event of Default with respect to such series or all series, as
the case may be, and its consequences (including waivers obtained in connection
with a tender offer or exchange offer for Securities of such series or all
series or a solicitation of consents in respect of Securities of such series or
all series, provided that in each case such offer or solicitation is made to all
Holders of then outstanding Securities of such series or all series (but the
terms of such offer or solicitation may vary from series to series)), except (1)
a continuing Default or Event of Default 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) a continued Default in respect of a provision that under Section
9.02 cannot be amended or supplemented without the consent of each Holder
affected. Upon any such waiver, such Default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default or impair any right consequent thereon.

         SECTION 6.05 Control by Majority.

                  With respect to Securities of any series, the Holders of a
majority in principal amount of the then outstanding Securities of such series
may direct in writing the time, method and place of conducting any proceeding
for any remedy available to the Trustee or exercising any trust or power
conferred on it relating to or arising under an Event of Default described in
clause (1), (2), (3), (4), (7) or (8) of Section 6.01, and with respect to all
Securities, the Holders of a majority in principal amount of all the then
outstanding Securities affected may direct in writing the time, method and place
of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on it not relating to or arising under
such an Event of Default. However, the Trustee may refuse to follow any
direction that conflicts with applicable law or this Indenture, that the Trustee
determines may be unduly prejudicial to the rights of other Holders, or that may
involve the Trustee in personal liability; provided, however, that the Trustee
may take any other action deemed proper by the Trustee that is not inconsistent
with such direction. Prior to taking any action hereunder, the Trustee shall be
entitled to indemnification satisfactory to it in its absolute discretion from
Holders indemnifying the Trustee against all losses and expenses caused by
taking or not taking such action.

         SECTION 6.06 Limitations on Suits.

                  Subject to Section 6.07 hereof, a Holder of a Security of any
series may pursue a remedy with respect to this Indenture or the Securities of
such series only if:

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

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

                                      -34-

<PAGE>

                  (3)      such Holder or Holders provide to the Trustee
         indemnity reasonably satisfactory to the Trustee against any loss,
         liability or expense;

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

                  (5)      during such 60-day period the Holders of a majority
         in principal amount of the Securities of that series do not give the
         Trustee a direction inconsistent with the request.

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

         SECTION 6.07 Rights of Holders to Receive Payment.

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

         SECTION 6.08 Collection Suit by Trustee.

                  If an Event of Default specified in clause (1) or (2) of
Section 6.01 hereof occurs and is continuing, the Trustee is authorized to
recover judgment in its own name and as trustee of an express trust against the
Company for the amount of principal, premium (if any), interest and any
Additional Amounts remaining unpaid on the Securities of the series affected by
the Event of Default, and interest on overdue principal and premium, if any,
and, to the extent lawful, interest on overdue interest, and such further amount
as shall be sufficient to cover the costs and expenses of collection, including
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel.

         SECTION 6.09 Trustee May File Proofs of Claim.

                  The Trustee is authorized to file such proofs of claim and
other papers or documents and to take such actions, including participating as a
member, voting or otherwise, of any committee of creditors, as may be necessary
or advisable to have the claims of the Trustee (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel) and the Holders allowed in any judicial proceedings
relative to the Company or its creditors or properties and shall be entitled and
empowered to collect, receive and distribute any money or other property payable
or deliverable on any such claims and any Bankruptcy Custodian in any such
judicial proceeding is hereby authorized by each Holder to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07. To the extent that the payment of any such compensation, expenses,
disbursements and advances of the Trustee, its

                                      -35-

<PAGE>

agents and counsel, and any other amounts due the Trustee under Section 7.07 out
of the estate in any such proceeding, shall be denied for any reason, payment of
the same shall be secured by a lien on, and shall be paid out of, any and all
distributions, dividends, money, securities and other properties which the
Holders of the Securities may be entitled to receive in such proceeding whether
in liquidation or under any plan of reorganization or arrangement or otherwise.
Nothing herein contained shall be deemed to authorize the Trustee to authorize
or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

         SECTION 6.10 Priorities.

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

                           First: to the Trustee for amounts due under Section
                  7.07;

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

                           Third: to the Company or to such party as a court of
                  competent jurisdiction shall direct.

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

                  To the fullest extent allowed under applicable law, if for the
purpose of obtaining a judgment against the Company in any court it is necessary
to convert the sum due in respect of the principal of, premium (if any) or
interest on or any Additional Amounts with respect to 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
Business Day in the City of New York 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 6.10 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 6.11 Undertaking for Costs.

                  In any suit for the enforcement of any right or remedy under
this Indenture or in any suit against the Trustee for any action taken or
omitted by it as a trustee, a court in its discretion may require the filing by
any party litigant in the suit of an undertaking to pay the costs of the suit,
and the court in its discretion may assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a
Holder pursuant to Section 6.07, or a suit by a Holder or Holders of more than
10% in principal amount of the then outstanding Securities of any series.

                                   ARTICLE VII
                                     TRUSTEE

         SECTION 7.01 Duties of Trustee.

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

                  (b)      Except during the continuance of an Event of Default
with respect to the Securities of any series:

                  (1)      the Trustee need perform only those duties that are
         specifically set forth in this Indenture and no others, and no implied
         covenants or obligations shall be read into this Indenture against the
         Trustee; and

                  (2)      in the absence of bad faith on its part, the Trustee
         may conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture. However, the Trustee shall examine such certificates
         and opinions to determine whether, on their face, they appear to
         conform to the requirements of this Indenture.

                  (c)      The Trustee may not be relieved from liabilities for
its own negligent action, its own negligent failure to act or its own willful
misconduct, except that:

                  (1)      this paragraph does not limit the effect of Section
         7.01(b);

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

                  (3)      the Trustee shall not be liable with respect to any
         action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 6.05.

                                      -37-

<PAGE>

                  (d)      Whether or not therein expressly so provided, every
provision of this Indenture that in any way relates to the Trustee is subject to
the provisions of this Section 7.01.

                  (e)      No provision of this Indenture shall require the
Trustee to expend or risk its own funds or incur any liability. The Trustee may
refuse to perform any duty or exercise any right or power unless it receives
indemnity reasonably satisfactory to it against any loss, liability or expense.

                  (f)      The Trustee shall not be liable for interest on any
money received by it except as the Trustee may agree in writing with the
Company. Money held in trust by the Trustee need not be segregated from other
funds except to the extent required by law. All money received by the Trustee
shall, until applied as herein provided, be held in trust for the payment of the
principal of, premium (if any) and interest on and any Additional Amounts with
respect to the Securities.

         SECTION 7.02 Rights of Trustee.

                  (a)      The Trustee may rely on any document believed by it
to be genuine and to have been signed or presented by the proper Person. The
Trustee need not investigate any fact or matter stated in the document.

                  (b)      Before the Trustee acts or refrains from acting, it
may require instruction, an Officers' Certificate or an Opinion of Counsel or
both to be provided. The Trustee shall not be liable for any action it takes or
omits to take in good faith in reliance on such instruction, Officers'
Certificate or Opinion of Counsel. The Trustee may consult at the Company's
expense with counsel and the written advice of such counsel or any Opinion of
Counsel shall be full and complete authorization and protection in respect of
any action taken, suffered or omitted by it hereunder in good faith and in
reliance thereon.

                  (c)      The Trustee may act through agents and shall not be
responsible for the misconduct or negligence of any agent appointed with due
care.

                  (d)      The Trustee shall not be liable for any action it
takes or omits to take in good faith which it believes to be authorized or
within its rights or powers conferred upon it by this Indenture.

                  (e)      Unless otherwise specifically provided in this
Indenture, any demand, request, direction or notice from the Company shall be
sufficient if signed by an Officer of the Company.

                  (f)      the Trustee shall be under no obligation to exercise
any of the trusts or powers vested in it by this Indenture at the request, order
or direction of any of the Holders pursuant to the provisions of this Indenture,
unless such Holders shall have offered to the Trustee reasonable security and
indemnity against the costs, expenses and liabilities which might be incurred
therein or thereby.

<PAGE>

         SECTION 7.03 May Hold Securities.

                  The Trustee in its individual or any other capacity may become
the owner or pledgee of Securities and may otherwise deal with the Company or
any of its Affiliates with the same rights it would have if it were not Trustee.
Any Agent may do the same with like rights and duties. However, the Trustee is
subject to Sections 7.10 and 7.11.

         SECTION 7.04 Trustee's Disclaimer.

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

         SECTION 7.05 Notice of Defaults.

                  If a Default or Event of Default with respect to the
Securities of any series occurs and is continuing and it is known to the
Trustee, the Trustee shall mail to Holders of Securities of such series a notice
of the Default or Event of Default within 90 days after it occurs. Except in the
case of a Default or Event of Default in payment of principal of, premium (if
any) and interest on and any Additional Amounts or any sinking fund installment
with respect to the Securities of such series, the Trustee may withhold the
notice if and so long as a committee of its Trust Officers in good faith
determines that withholding the notice is in the interests of Holders of
Securities of such series.

         SECTION 7.06 Reports by Trustee to Holders.

                  Within 60 days after May 15 of each year after the execution
of this Indenture, the Trustee shall mail to Holders of a series and the Company
a brief report dated as of such reporting date that complies with TIA Section
313(a); provided, however, that if no event described in TIA Section 313(a) has
occurred within the twelve months preceding the reporting date with respect to a
series, no report need be transmitted to Holders of such series. The Trustee
also shall comply with TIA Section 313(b). The Trustee shall also transmit by
mail all reports if and as required by TIA Sections 313(c) and 313(d).

                  A copy of each report shall be filed by the Company with the
SEC and each securities exchange, if any, on which the Securities of such series
are listed. The Company shall notify the Trustee in writing if and when any
series of Securities is listed on any securities exchange and of the delisting
thereof.

         SECTION 7.07 Compensation and Indemnity.

                  The Company agrees to pay to the Person acting as Trustee
hereunder compensation for its acceptance of this Indenture and services
hereunder as agreed upon in a separate fee agreement. The Trustee's compensation
shall not be limited by any law on compensation of a trustee of an express
trust. The Company agrees to reimburse the Trustee

                                      -39-

<PAGE>

upon request for all reasonable disbursements, advances and expenses incurred by
it. Such expenses shall include the reasonable compensation, disbursements and
expenses of the Trustee's agents and counsel.

                  The Company hereby indemnifies the Trustee, and each of its
officers, directors, counsel and agents, against any loss, liability or expense
(including, but not limited to reasonable attorneys' fees and expenses) incurred
by it arising out of or in connection with the acceptance or administration of
its duties under this Indenture and of defending itself against any claims
(whether asserted by any Holder, the Company or otherwise), except as set forth
in the next paragraph. The Trustee shall notify the Company promptly of any
claim for which it may seek indemnity. The Company shall defend the claim and
the Trustee shall cooperate in the defense. The Trustee may have separate
counsel and the Company shall pay the fees and expenses of such counsel. The
Company need not pay for any settlement made without its consent.

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

                  To secure the payment obligations of the Company in this
Section 7.07, the Trustee shall have a lien prior to the Securities on all money
or property held or collected by the Trustee, except that held in trust to pay
principal of, premium (if any) and interest on and any Additional Amounts with
respect to Securities of any series. Such lien and the indemnity obligation
under this Section 7.07 shall survive the satisfaction and discharge of this
Indenture.

                  When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.01(6) or (7) occurs, the expenses and
the compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

         SECTION 7.08 Replacement of Trustee.

                  A resignation or removal of the Trustee and appointment of a
successor Trustee shall become effective only upon the successor Trustee's
acceptance of appointment as provided in this Section 7.08.

                  The Trustee may resign and be discharged at any time with
respect to the Securities of one or more series by so notifying the Company. The
Holders of a majority in principal amount of the then outstanding Securities of
any series may remove the Trustee with respect to the Securities of such series
by so notifying the Trustee and the Company. The Company may remove the Trustee
if:

                  (1)      the Trustee fails to comply with Section 7.10;

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

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

                  (4)      the Trustee otherwise becomes incapable of acting.

                                      -40-

<PAGE>

                  If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason, with respect to the Securities of one or
more series, the Company shall promptly appoint a successor Trustee or Trustees
with respect to the Securities of that or those series (it being understood that
any such successor Trustee may be appointed with respect to the Securities of
one or more or all of such series and that at any time there shall be only one
Trustee with respect to the Securities of any particular series). Within one
year after the successor Trustee with respect to the Securities of any series
takes office, the Holders of a majority in principal amount of the Securities of
such series then outstanding may appoint a successor Trustee to replace the
successor Trustee appointed by the Company.

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

                  If the Trustee with respect to the Securities of a series
fails to comply with Section 7.10, any Holder of Securities of such series may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee with respect to the Securities of such
series.

                  In case of the appointment of a successor Trustee with respect
to all Securities, each such successor Trustee shall deliver a written
acceptance of its appointment to the retiring Trustee and to the Company.
Thereupon the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee shall have all the rights, powers and
duties of the retiring Trustee under this Indenture. The successor Trustee shall
mail a notice of its succession to Holders. The retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee, subject to
the lien provided for in Section 7.07.

                  In case of the appointment of a successor Trustee with respect
to the Securities of one or more (but not all) series, the Company, the retiring
Trustee and each successor Trustee with respect to the Securities of one or more
(but not all) series shall execute and deliver an indenture supplemental hereto
in which each successor Trustee shall accept such appointment and that (1) shall
confer to each successor Trustee all the rights, powers and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (2) if the retiring Trustee
is not retiring with respect to all Securities, shall confirm that all the
rights, powers and duties of the retiring Trustee with respect to the Securities
of that or those series as to which the retiring Trustee is not retiring shall
continue to be vested in the retiring Trustee and (3) shall add to or change any
of the provisions of this Indenture as shall be necessary to provide for or
facilitate the administration of the trusts hereunder by more than one Trustee.
Nothing herein or in such supplemental indenture shall constitute such Trustees
as co-trustees of the same trust, and each such Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee. Upon the execution and delivery of such
supplemental indenture, the resignation or removal of the retiring Trustee shall
become effective to the extent provided therein and each such successor Trustee
shall have all the rights, powers and duties of the retiring Trustee with
respect to the Securities of that or those series to which the appointment of
such

                                      -41-

successor Trustee relates. On request of the Company or any successor Trustee,
such retiring Trustee shall transfer to such successor Trustee all property held
by such retiring Trustee as Trustee with respect to the Securities of that or
those series to which the appointment of such successor Trustee relates.

                  Notwithstanding replacement of the Trustee or Trustees
pursuant to this Section 7.08, the obligations of the Company under Section 7.07
shall continue for the benefit of the retiring Trustee or Trustees.

         SECTION 7.09 Successor Trustee by Merger, etc.

                  Subject to Section 7.10, if the Trustee consolidates, merges
or converts into, or transfers all or substantially all of its corporate trust
business to, another corporation, the successor corporation without any further
act shall be the successor Trustee; provided, however, that in the case of a
transfer of all or substantially all of its corporate trust business to another
corporation, the transferee corporation expressly assumes all of the Trustee's
liabilities hereunder.

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

         SECTION 7.10 Eligibility; Disqualification.

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

                  The Indenture shall always have a Trustee who satisfies the
requirements of TIA Sections 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee is
subject to and shall comply with the provisions of TIA Section 310(b) during the
period of time required by this Indenture. Nothing in this Indenture shall
prevent the Trustee from filing with the SEC the application referred to in the
penultimate paragraph of TIA Section 310(b).

         SECTION 7.11 Preferential Collection of Claims Against the Company.

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

                             DISCHARGE OF INDENTURE

         SECTION 8.01 Termination of the Company's Obligations.

                  (a)      This Indenture shall cease to be of further effect
with respect to the Securities of a series (except that the Company's
obligations under Section 7.07, the Trustee's and Paying Agent's obligations
under Section 8.03 and the rights, powers, protections and privileges accorded
the Trustee under Article VII shall survive), and the Trustee, on demand of the
Company, shall execute proper instruments acknowledging the satisfaction and
discharge of this Indenture with respect to the Securities of such series, when:

                  (1)      either

                           (A)      all outstanding Securities of such series
                  theretofore authenticated and issued (other than destroyed,
                  lost or stolen Securities that have been replaced or paid)
                  have been delivered to the Trustee for cancellation; or

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

                                    (i)      have become due and payable, or

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

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

                  and, in the case of clause (i), (ii) or (iii) above, the
                  Company has irrevocably deposited or caused to be deposited
                  with the Trustee as funds (immediately available to the
                  Holders in the case of clause (i)) in trust for such purpose
                  (x) cash in an amount, or (y) Government Obligations, maturing
                  as to principal and interest at such times and in such amounts
                  as will ensure the availability of cash in an amount or (z) a
                  combination thereof, which will be sufficient, in the opinion
                  (in the case of clauses (y) and (z)) of a nationally
                  recognized firm of independent public accountants expressed in
                  a written certification thereof delivered to the Trustee, to
                  pay and discharge the entire indebtedness on the Securities of
                  such series for principal and interest to the date of such
                  deposit (in the case of Securities which have become due and
                  payable) or for principal, premium, if any, and interest to
                  the Stated Maturity or Redemption Date, as the case may be; or

                           (C)      the Company has properly fulfilled such
                  other means of satisfaction and discharge as is specified, as
                  contemplated by Section 2.01, to be applicable to the
                  Securities of such series;

                                      -43-

<PAGE>

                  (2)      the Company has paid or caused to be paid all other
         sums payable by it hereunder with respect to the Securities of such
         series; and

                  (3)      the Company has delivered to the Trustee an Officers'
         Certificate stating that all conditions precedent to satisfaction and
         discharge of this Indenture with respect to the Securities of such
         series have been complied with, together with an Opinion of Counsel to
         the same effect.

                  (b)      Unless this Section 8.01(b) is specified as not being
applicable to Securities of a series as contemplated by Section 2.01, the
Company may, at its option, terminate certain of its obligations under this
Indenture ("covenant defeasance") with respect to the Securities of a series if:

                  (1)      the Company has irrevocably deposited or caused to be
         irrevocably deposited with the Trustee as trust funds in trust for the
         purpose of making the following payments, specifically pledged as
         security for and dedicated solely to the benefit of the Holders of
         Securities of such series, (i) money in the currency in which payment
         of the Securities of such series is to be made in an amount, or (ii)
         Government Obligations with respect to such series, maturing as to
         principal and interest at such times and in such amounts as will ensure
         the availability of money in the currency in which payment of the
         Securities of such series is to be made in an amount or (iii) a
         combination thereof, that is sufficient, in the opinion (in the case of
         clauses (ii) and (iii)) of a nationally recognized firm of independent
         public accountants expressed in a written certification thereof
         delivered to the Trustee, to pay the principal of and premium (if any)
         and interest on all Securities of such series on each date that such
         principal, premium (if any) or interest is due and payable and (at the
         Stated Maturity thereof or upon redemption as provided in Section
         8.01(e)) to pay all other sums payable by it hereunder; provided that
         the Trustee shall have been irrevocably instructed to apply such money
         and/or the proceeds of such Government Obligations to the payment of
         said principal, premium (if any) and interest with respect to the
         Securities of such series as the same shall become due;

                  (2)      the Company has delivered to the Trustee an Officers'
         Certificate stating that all conditions precedent to satisfaction and
         discharge of this Indenture with respect to the Securities of such
         series have been complied with, and an Opinion of Counsel to the same
         effect;

                  (3)      no Default or Event of Default with respect to the
         Securities of such series shall have occurred and be continuing on the
         date of such deposit;

                  (4)      the Company shall have delivered to the Trustee an
         Opinion of Counsel from a nationally recognized counsel acceptable to
         the Trustee or a tax ruling to the effect that the Holders will not
         recognize income, gain or loss for U.S. Federal income tax purposes as
         a result of the Company's exercise of its option under this Section
         8.01(b) and will be subject to U.S. Federal income tax on the same
         amount and in the same manner and at the same times as would have been
         the case if such option had not been exercised;

                                      -44-

<PAGE>

                  (5)      the Company has complied with any additional
         conditions specified pursuant to Section 2.01 to be applicable to the
         discharge of Securities of such series pursuant to this Section 8.01;
         and

                  (6)      such deposit and discharge shall not cause the
         Trustee to have a conflicting interest as defined in TIA Section
         310(b).

                  In such event, this Indenture shall cease to be of further
effect (except as set forth in this paragraph), and the Trustee, on demand of
the Company, shall execute proper instruments acknowledging satisfaction and
discharge under this Indenture. However, the Company's obligations in Sections
2.05, 2.06, 2.07, 2.08, 2.09, 4.01, 4.02, 7.07, 7.08 and 8.04, the Trustee's and
Paying Agent's obligations in Section 8.03 and the rights, powers, protections
and privileges accorded the Trustee under Article VII shall survive until all
Securities of such series are no longer outstanding. Thereafter, only the
Company's obligations in Section 7.07 and the Trustee's and Paying Agent's
obligations in Section 8.03 shall survive with respect to Securities of such
series.

                  After such irrevocable deposit made pursuant to this Section
8.01(b) and satisfaction of the other conditions set forth herein, the Trustee
upon request shall acknowledge in writing the discharge of the Company's
obligations under this Indenture with respect to the Securities of such series
except for those surviving obligations specified above.

                  In order to have money available on a payment date to pay
principal of or premium (if any) or interest on the Securities, the Government
Obligations shall be payable as to principal or interest on or before such
payment date in such amounts as will provide the necessary money. Government
Obligations shall not be callable at the issuer's option.

                  (c)      If the Company has previously complied or is
concurrently complying with Section 8.01(b) (other than any additional
conditions specified pursuant to Section 2.01 that are expressly applicable only
to covenant defeasance) with respect to Securities of a series, then, unless
this Section 8.01(c) is specified as not being applicable to Securities of such
series as contemplated by Section 2.01, the Company may elect to be discharged
("legal defeasance") from its obligations to make payments with respect to
Securities of such series, if:

                  (1)      no Default or Event of Default under clauses (6) and
         (7) of Section 6.01 hereof shall have occurred at any time during the
         period ending on the 91st day after the date of deposit contemplated by
         Section 8.01(b) (it being understood that this condition shall not be
         deemed satisfied until the expiration of such period);

                  (2)      unless otherwise specified with respect to Securities
         of such series as contemplated by Section 2.01, the Company has
         delivered to the Trustee an Opinion of Counsel from a nationally
         recognized counsel acceptable to the Trustee to the effect referred to
         in Section 8.01(b)(4) with respect to such legal defeasance, which
         opinion is based on (i) a private ruling of the Internal Revenue
         Service addressed to the Company, (ii) a published ruling of the
         Internal Revenue Service or (iii) a change in the applicable federal
         income tax law (including regulations) after the date of this
         Indenture;

                                      -45-

<PAGE>

                  (3)      the Company has complied with any other conditions
         specified pursuant to Section 2.01 to be applicable to the legal
         defeasance of Securities of such series pursuant to this Section
         8.01(c); and

                  (4)      the Company has delivered to the Trustee a Company
         Request requesting such legal defeasance of the Securities of such
         series and an Officers' Certificate stating that all conditions
         precedent with respect to such legal defeasance of the Securities of
         such series have been complied with, together with an Opinion of
         Counsel to the same effect.

                  In such event, the Company will be discharged from its
obligations under this Indenture and the Securities of such series to pay
principal of, premium (if any) and interest on and any Additional Amounts with
respect to Securities of such series, the Company's obligations under Sections
4.01 and 4.02 shall terminate with respect to such Securities, and the entire
indebtedness of the Company evidenced by such Securities shall be deemed paid
and discharged.

                  (d)      If and to the extent additional or alternative means
of satisfaction, discharge or defeasance of Securities of a series are specified
to be applicable to such series as contemplated by Section 2.01, the Company may
terminate any or all of its obligations under this Indenture with respect to
Securities of a series and any or all of its obligations under the Securities of
such series if it fulfills such other means of satisfaction and discharge as may
be so specified, as contemplated by Section 2.01, to be applicable to the
Securities of such series.

                  (e)      If Securities of any series subject to subsections
(a), (b), (c) or (d) of this Section 8.01 are to be redeemed prior to their
Stated Maturity, whether pursuant to any optional redemption provisions or in
accordance with any mandatory or optional sinking fund provisions, the terms of
the applicable trust arrangement shall provide for such redemption, and the
Company shall make such arrangements as are reasonably satisfactory to the
Trustee for the giving of notice of redemption by the Trustee in the name, and
at the expense, of the Company.

         SECTION 8.02 Application of Trust Money.

                  The Trustee or a trustee satisfactory to the Trustee and the
Company shall hold in trust money or Government Obligations deposited with it
pursuant to Section 8.01 hereof. It shall apply the deposited money and the
money from Government Obligations through the Paying Agent and in accordance
with this Indenture to the payment of principal of, premium (if any) and
interest on and any Additional Amounts with respect to the Securities of the
series with respect to which the deposit was made.

         SECTION 8.03 Repayment to Company.

                  The Trustee and the Paying Agent shall promptly pay to the
Company upon written request any excess money or Government Obligations (or
proceeds therefrom) held by them at any time upon the written request of the
Company.

                  Subject to the requirements of any applicable abandoned
property laws, the Trustee and the Paying Agent shall pay to the Company upon
written request any money held by them for the payment of principal, premium (if
any), interest or any Additional Amounts that

                                      -46-

<PAGE>

remains unclaimed for two years after the date upon which such payment shall
have become due. After payment to the Company, Holders entitled to the money
must look to the Company for payment as general creditors unless an applicable
abandoned property law designates another Person, and all liability of the
Trustee and the Paying Agent with respect to such money shall cease.

         SECTION 8.04 Reinstatement.

                  If the Trustee or the Paying Agent is unable to apply any
money or Government Obligations deposited with respect to Securities of any
series in accordance with Section 8.01 by reason of any legal proceeding or by
reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the
obligations of the Company under this Indenture with respect to the Securities
of such series and under the Securities of such series shall be revived and
reinstated as though no deposit had occurred pursuant to Section 8.01 until such
time as the Trustee or the Paying Agent is permitted to apply all such money or
Government Obligations in accordance with Section 8.01; provided, however, that
if the Company has made any payment of principal of, premium (if any) or
interest on or any Additional Amounts with respect to any Securities because of
the reinstatement of its obligations, the Company shall be subrogated to the
rights of the Holders of such Securities to receive such payment from the money
or Government Obligations held by the Trustee or the Paying Agent.

                     SUPPLEMENTAL INDENTURES AND AMENDMENTS

         SECTION 9.01 Without Consent of Holders.

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

                  (6)      to add to the covenants of the Company for the
         benefit of the Holders of all or any series of Securities (and if such
         covenants are to be for the benefit of less than all series of

                  (8)      to change or eliminate any of the provisions of this
         Indenture; provided that any such change or elimination shall become
         effective only when there is no outstanding Security of any series
         created prior to the execution of such amendment or supplemental
         indenture that is adversely affected in any material respect by such
         change in or elimination of such provision;

                  (9)      to establish the form or terms of Securities of any

         adversely affect the interest of the Holders of Securities of such
         series or any other series of Securities in any material respect;

                  (11)     to evidence and provide for the acceptance of

                  (12)     to make any other change that does not adversely

                  Upon the request of the Company, accompanied by a Board
Resolution, and upon receipt by the Trustee of the documents described in
Section 9.06, the Trustee shall join with the Company in the execution of any
supplemental indenture authorized or permitted by the terms of this Indenture
and make any further appropriate agreements and stipulations that may be therein
contained.

         SECTION 9.02 With Consent of Holders.

described in Section 9.06, the Trustee shall join with the Company in the
execution of such amendment or supplemental indenture.

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

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

                  However, without the consent of each Holder affected, an
amendment, supplement or waiver under this Section 9.02 may not:

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

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

                  (3)      reduce the principal of or any premium on or any
         mandatory sinking fund payment with respect to, or change the Stated
         Maturity of, any Security or reduce the amount of the principal of an
         Original Issue Discount Security that would be due and payable upon a
         declaration of acceleration of the Stated Maturity thereof pursuant to
         Section 6.02;

                  (4)      reduce the premium, if any, payable upon the
         redemption of any Security or change the time at which any Security may
         or shall be redeemed;

                  (5)      change any obligation of the Company to pay any
         Additional Amounts with respect to any Security;

                  (6)      change the coin or currency or currencies (including
         composite currencies) in which any Security or any premium, interest or
         any Additional Amounts with respect thereto are payable;

                  (7)      impair the right to institute suit for the
         enforcement of any payment of principal of, premium (if any) or
         interest on or any Additional Amounts with respect to any Security
         pursuant to Sections 6.07 and 6.08, except as limited by Section 6.06;

                                      -49-

<PAGE>

                  (8)      make any change in the percentage of principal amount
         of Securities necessary to waive compliance with certain provisions of
         this Indenture pursuant to Section 6.04 or 6.07 or make any change in
         this sentence of Section 9.02; or

                  (9)      waive a continuing Default or Event of Default in the
         payment of principal of, premium (if any) or interest on or any
         Additional Amounts with respect to the Securities.

                  A supplemental indenture that changes or eliminates any
covenant or other provision of this Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities, or which
modifies the rights of the Holders of Securities of such series with respect to
such covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series.

                  The right of any Holder to participate in any consent required
or sought pursuant to any provision of this Indenture (and the obligation of the
Company to obtain any such consent otherwise required from such Holder) may be
subject to the requirement that such Holder shall have been the Holder of record
of any Securities with respect to which such consent is required or sought as of
a date identified by the Company in a notice furnished to Holders in accordance
with the terms of this Indenture.

                  After an amendment, supplement or waiver under this Section
9.02 becomes effective, the Company shall mail to the Holders of each Security
affected thereby a notice briefly describing the amendment, supplement or
waiver. Any failure of the Company to mail such notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such
amendment, supplement or waiver.

         SECTION 9.03 Compliance with Trust Indenture Act.

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

         SECTION 9.04 Revocation and Effect of Consents.

                  Until an amendment, supplement or waiver becomes effective, a
consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Security or portion of a Security that evidences the same
debt as the consenting Holder's Security, even if notation of the consent is not
made on any Security. However, any such Holder or subsequent Holder may revoke
the consent as to his or her Security or portion of a Security if the Trustee
receives written notice of revocation before a date and time therefor identified
by the Company in a notice furnished to such Holder in accordance with the terms
of this Indenture or, if no such date and time shall be identified, the date the
amendment, supplement or waiver becomes effective. An amendment, supplement or
waiver becomes effective in accordance with its terms and thereafter binds every
Holder.

                  The Company may, but shall not be obligated to, fix a record
date (which need not comply with TIA Section 316(c)) for the purpose of
determining the Holders entitled to consent to any amendment, supplement or
waiver or to take any other action under this Indenture. If a

                                      -50-

<PAGE>

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

                  After an amendment, supplement or waiver becomes effective, it
shall bind every Holder, unless it is of the type described in any of clauses
(1) through (9) of Section 9.02 hereof. In such case, the amendment, supplement
or waiver shall bind each Holder who has consented to it and every subsequent
Holder that evidences the same debt as the consenting Holder's Security.

         SECTION 9.05 Notation on or Exchange of Securities.

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

                  Securities of any series authenticated and delivered after the
execution of any amendment or supplement may, and shall if required by the
Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such amendment or supplement.

         SECTION 9.06 Trustee to Sign Amendments, etc.

                  The Trustee shall sign any amendment or supplement authorized
pursuant to this Article if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. If it does,
the Trustee may, but need not, sign it. In signing or refusing to sign such
amendment or supplement, the Trustee shall be entitled to receive, and, subject
to Section 7.01 hereof, shall be fully protected in relying upon, an Officers'
Certificate and an Opinion of Counsel provided at the expense of the Company as
conclusive evidence that such amendment or supplement is authorized or permitted
by this Indenture, that it is not inconsistent herewith, and that it will be
valid and binding upon the Company in accordance with its terms.

         SECTION 10.01 Trust Indenture Act Controls.

conflicts with the duties imposed by operation of TIA Section 318(c), the
imposed duties shall control.

                  In case by reason of the suspension of regular mail service,
or by reason of any other cause, it shall be impossible to mail any notice
required by this Indenture, then such method of notification as shall be made

                                   ARTICLE I

                          Floating Rate Notes Due 2005

                  SECTION 1.01 Establishment and Terms

                  There is hereby established a new series of Securities to be
issued under the Indenture, to be designated as the Company's Senior Notes due

issued in definitive fully registered form without coupons.

Company shall set forth in an Officer's Certificate the following information:

                           Floating Rate Notes to be authenticated and delivered

                           interest shall accrue; and

                  (iii)    whether such Additional Floating Rate Notes shall be

                           within the meaning of Rule 144(a)(3) of the
                           Securities Act (a "Restricted Note") or a Note that
                           is not a Restricted Note (an "Unrestricted Note);
                           provided, however, that the Trustee shall be entitled
                           to request and conclusively rely on an opinion of
                           counsel with respect to whether any Note constitutes
                           a Restricted Note.

                  For purposes of the Indenture, Floating Rate Notes will not be
deemed to be Additional Floating Rate Notes unless the maturity date, Interest
Payment Dates, record date and interest rate are identical to the Initial
Floating Rate Notes. The Initial Floating Rate Notes and the Additional Floating
Rate Notes shall be considered collectively as a single class for all purposes
of this Indenture. Holders of the Initial Floating Rate Notes and the Additional
Floating Rate Notes will vote and consent together on all matters to which such
Holders are entitled to vote or consent as one class, and none of the Holders of
the Initial Floating Rate Notes or the Additional Floating Rate Notes shall have
the right to vote or consent as a separate class on any matter to which such
Holders are entitled to vote or consent.

                  The Floating Rate Notes shall be issued in the form of one or
more Global Securities in substantially the form set out in Exhibit A and as
further provided in Article III. The initial Depositary with respect to the
Floating Rate Notes shall be The Depository Trust Company ("DTC").

                  All payments of principal, premium (if any) and interest on
the Fixed Rate Notes shall be made in accordance with Section 4.01 of the
Original Indenture. No Additional Amounts will be payable on the Fixed Rate
Notes.

                  SECTION 1.02 Maturity, Payment of Principal and Interest. The
Floating Rate Notes will mature on October 17, 2005. The Floating Rate Notes
will bear interest for each Interest Period at a rate determined by the
Calculation Agent. The interest rate on the Floating Rate Notes for a particular
Interest Period will be a per annum rate equal to the Three-Month LIBOR Rate, as
determined on the Interest Determination Date, plus 1.50%, for each interest
period. The Interest Periods with respect to the Floating Rate Notes are:
January 18 though April 17; April 18 through July 17; July 18 through October
17; and October 18 through January 17, except that the first Interest Period
with respect to the Initial Floating Rate Notes will be from October 17, 2003
through January 17, 2004. The Interest Determination Date with respect to the

                                      -2-
<PAGE>

Floating Rate Notes will be the second London Business Day preceding the
commencement of an Interest Period, except that the Interest Determination Date
for the first Interest Period with respect to the Initial Floating Rate Notes
will be October 15, 2003. Interest will be calculated on the basis of the actual
number of days in an interest period and a 360-day year. Dollar amounts
resulting from such calculation will be rounded down to the nearest cent, with
one-half cent being rounded upward. The interest rate for the first Interest
Period with respect to the Initial Floating Rate Notes is 2.65625%.

                  The Interest Payment Dates with respect to the Floating Rate
Notes will be January 17, April 17, July 17 and October 17 of each year. The
first Interest Payment Date with respect to the Initial Floating Rate Notes will
be January 17, 2004. Interest shall be paid to the Person in whose name the
applicable Note is registered at the close of business on January 1, in the case
of a January 17 Interest Payment Date, April 1, in the case of a April 17
Interest Payment Date, July 1, in the case of a July 17 Interest Payment Date
and October 1, in the case of an October 17 Interest Payment Date. Interest on
the Initial Floating Rate Notes will accrue from October 17, 2003, or from the
most recent Interest Payment Date to which interest has been paid or duly
provided for.

                  The following definitions are used in the calculation of the
interest rate:

                  "Three-Month LIBOR Rate" means the rate for deposits in
amounts of at least $1,000,000 U.S. dollars for the 3-month period commencing on
the applicable Interest Determination Date which appears on Telerate Page 3750
at approximately 11:00 a.m., London time, on the second London banking day prior
to the applicable Interest Reset Date. If Telerate page 3750 is replaced by
another service or ceases to exist, the Calculation Agent (after consultation
with the Company) will use the replacing service or such other service that may
be nominated by the British Bankers' Association for the purpose of displaying
such rate for U.S. dollar deposits. If this rate does not appear on Telerate
Page 3750 at approximately 11:00 a.m London time, on the second London banking
day prior to the applicable Interest Reset Date, the Calculation Agent will
determine the rate on the basis of the rates at which deposits in U.S. dollars
are offered by four major banks in the London interbank market (selected by the
Calculation Agent) to prime banks in the London interbank market for a period of
three months commencing on that Interest Determination Date and in a principal
amount equal to an amount not less than $1,000,000 that is representative for a
single transaction in such market at such time. In such case, the Calculation
Agent will request the principal London office of each of the aforesaid major
banks to provide a quotation of such rate. If at least two such quotations are
provided, the rate for that Interest Determination Date will be the arithmetic
average of the quotations, and, if fewer than two quotations are provided as
requested, the Calculation Agent will select three major banks in The City of
New York to provide a quotation of the rate offered by them at approximately
11:00 a.m., New York City time, on the Interest Determination Date for loans in
U.S. dollars to leading European banks for a period of three months commencing
on that Interest Determination Date and in a principal amount equal to an amount
not less than $1,000,000 that is representative of a single transaction in such
market at such time. If three quotation are provided, the rate for that Interest
Determination Date will be the arithmetic average of the three rates quoted;
otherwise, the rate for that Interest Determination Date will be set equal to
the rate of LIBOR for the then-current interest period.

                  A London banking day is any day in which dealings in U.S.
dollars are transacted in the London interbank market.

                  "Telerate Page 3750" means the display page so designated on
the Telerate Service (or such other page as may replace such page on that
service for the purpose of displaying London interbank offered rates of major
banks). The interest rate on the Floating Rate Notes will in no event be higher
than the maximum rate permitted by New York law as the same may be modified by
United States law of general application.

                  SECTION 1.03 Denominations. The Floating Rate Notes shall be
issued in denominations of $1,000 or any integral multiple thereof.

                  SECTION 1.04 Redemption. The Floating Rate Notes are not
redeemable by the Company at any time. The Floating Rate Notes will not be
subject to a sinking fund.

                  SECTION 1.05 Transfer Restrictions. The Floating Rate Notes
shall be subject to the restrictions on transfer and exchange set forth in
Section 3.01, which restrictions on transfer and exchange shall amend,
supplement, modify or supersede those contained in Article II of the Original
Indenture to the extent applicable.

                  SECTION 1.06 Paying Agent and Calculation Agent. The Company
initially appoints the Trustee as Paying Agent and J.P. Morgan Securities Inc.
as Calculation Agent with respect to the Floating Rate Notes (the "Calculation
Agent").

                  SECTION 1.07 Calculation of Interest Rate by the Calculation
Agent. The Calculation Agent will calculate the interest rate applicable to the
Floating Rate Notes for each Interest Period in accordance with the provisions
of this Article I. Promptly upon determination, the Calculation Agent will
inform the Trustee and the Company of the interest rate for the next Interest
Period. Absent manifest error, the determination of the interest rate by the
Calculation Agent shall be binding and conclusive on all Holders of Floating
Rate Notes, the Trustee and the Company. Upon request by any Holder of Floating
Rate Notes, the Calculation Agent will provide notice of the interest rate in
effect on the Floating Rate Notes for the then-current Interest Period and, if
it has been determined, the interest rate to be in effect for the next
succeeding Interest Period.

                            Fixed Rate Notes due 2010

                  SECTION 2.01 Establishment and Terms.

                  There is hereby established a new series of Securities to be
issued under the Indenture, to be designated as the Company's 5 1/2% Senior
Notes due 2010 (the "Fixed Rate Notes" and, together with the Floating Rate
Notes, the "Notes"). The Fixed Rate Notes are being sold initially by the
Company pursuant to Rule 144A and Regulation S under the Act.

                  The aggregate principal amount of Fixed Rate Notes that may be
authenticated and delivered under this Indenture is unlimited. The Fixed Rate
Notes that are to be authenticated and delivered on the date hereof (the
"Initial Fixed Rate Notes" and, together with

                                      -4-
<PAGE>

the Initial Floating Rate Notes, the "Initial Notes") will be in an aggregate
principal amount of $750,000,000. The Fixed Rate Notes shall be issued in
definitive fully registered form.

                  With respect to any additional Fixed Rate Notes the Company
elects to issue under this Indenture (the "Additional Fixed Rate Notes" and,
together with the Additional Floating Rate Notes, the "Additional Notes"), the
Company shall set forth in an Officer's Certificate the following information:

                  (i)      the aggregate principal amount of such Additional
                           Fixed Rate Notes to be authenticated and delivered
                           pursuant to this Indenture;

                  (ii)     the issue price and the issue date of such Additional
                           Fixed Rate Notes, including the date from which
                           interest shall accrue; and

                  (iii)    whether such Additional Fixed Rate Notes shall be
                           Restricted Notes or Unrestricted Notes.

                  For purposes of the Indenture, Fixed Rate Notes will not be
deemed to be Additional Fixed Rate Notes unless the maturity date, Interest
Payment Dates, record date and maturity date are identical to the Initial Fixed
Rate Notes. The Initial Fixed Rate Notes and the Additional Fixed Rate Notes
shall be considered collectively as a single class for all purposes of this
Indenture. Holders of the Initial Fixed Rate Notes and the Additional Fixed Rate
Notes will vote and consent together on all matters to which such Holders are
entitled to vote or consent as one class, and none of the Holders of the Initial
Fixed Rate Notes or the Additional Fixed Rate Notes shall have the right to vote
or consent as a separate class on any matter to which such Holders are entitled
to vote or consent.

                  The Fixed Rate Notes shall be issued in the form of one or
more Global Securities in substantially the form set out in Exhibit B and as
further provided in Article III. The initial Depositary with respect to the
Notes shall be The Depository Trust Company ("DTC").

                  SECTION 2.02 Maturity, Payment of Principal and Interest.

                  The Fixed Rate Notes will mature on October 15, 2010.

respect to the Initial Fixed Rate Notes will be April 15, 2004. Interest shall
be paid to the Person in whose name the applicable Note is registered at the
close of business on October 1, in the case of a October 15 Interest Payment
Date, and April 1, in the case of an April 15 Interest Payment Date. Interest on
the Initial Fixed Rate Notes will accrue from October 17, 2003. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

                  All payments of principal, premium (if any) and interest on
the Fixed Rate Notes shall be made in accordance with Section 4.01 of the
Original Indenture. No Additional Amounts will be payable on the Fixed Rate
Notes.

                  SECTION 2.03 No Sinking Fund. The Fixed Rate Notes will not be
subject to a sinking fund.

                  SECTION 2.04 Optional Redemption. At any time and from time to
time the Fixed Rate Notes will be redeemable, in the Company's sole discretion,
in whole or in part, in principal amounts of $1,000 or any integral multiple of
$1,000 for an amount equal to the greater of:

                  (i)      100% of the principal amount of the Fixed Rate Notes;
                           and

                  (ii)     as determined by an Independent Investment Banker,
                           the sum of the present values of the Remaining
                           Scheduled Payments on the Fixed Rate Notes being
                           redeemed, discounted to the redemption date on a
                           semiannual basis (assuming a 360-day year consisting
                           of twelve 30-day months) at the Treasury Rate plus 25
                           basis points.

                  In the event of any such redemption, interest will accrue up
to and including the date of redemption. Unless there is a default in payment of
the Redemption Price on and after the Redemption Date, interest will cease to
accrue on the Fixed Rate Notes or portions thereof called for redemption.

                  The following defined terms used solely for purposes of this
Section 2.05 shall, unless the context otherwise requires, have the meanings
specified below for purposes of the Floating Rate Notes.

                  "Treasury Rate" means the rate per year, calculated on the
third day preceding the redemption date, equal to (i) the yield, under the
heading that represents the average for the immediately preceding week,
appearing in the most recently published statistical release designated
"H.15(519)" or any successor publication that is published weekly by the Board
of Governors of the Federal Reserve System and that establishes yields on
actively traded United States Treasury securities adjusted to constant maturity
under the caption "Treasury Constant Maturities," for the maturity corresponding
to the Comparable Treasury Issue; provided that if no maturity is within three
months before or after the maturity date for the Fixed Rate Notes, yields for
the two published maturities most closely corresponding to the Comparable
Treasury Issue will be determined and the Treasury Rate will be interpolated or
extrapolated from those yields on a straight line basis rounding to the nearest
month; or (ii) if that release, or any successor release, is not published
during the week preceding the calculation date or does not contain such yields,
the rate per year equal to the semiannual equivalent yield to maturity of the
Comparable Treasury Issue, calculated using a price for the Comparable Treasury
Issue (expressed as a percentage of its principal amount) equal to the
Comparable Treasury Price for that Redemption Date.

                  "Comparable Treasury Issue" means the United States Treasury
security selected by an Independent Investment Banker that would be used, at the
time of selection and in

                                      -6-
<PAGE>

accordance with customary financial practice, in pricing new issues of corporate
debt securities of comparable maturity to the remaining term of the Fixed Rate
Notes.

                  "Comparable Treasury Price" is (i) the average of the bid and
asked prices for the Comparable Treasury Issue (expressed as a percentage of its
principal amount) on the third Business Day preceding the Redemption Date, as
set forth in the daily statistical release (or any successor release) published
by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m.
Quotations for U.S. Government Securities"; or (ii) if such release (or any
successor release) is not published or does not contain such prices on such
Business Day (X) the average of the Reference Treasury Dealer Quotations for
that Redemption Date, after excluding the highest and lowest of the Reference
Treasury Dealer Quotations, or (Y) if the trustee obtains fewer than three
Reference Treasury Dealer Quotations, the average of all Reference Treasury
Dealer Quotations so received.

                  "Independent Investment Banker" means one of the Reference
Treasury Dealers that the Company appoints.

                  "Reference Treasury Dealer" means each of Citigroup Global
Markets Inc. (and its successors), Goldman, Sachs & Co. (and its successors),
J.P. Morgan Securities Inc. (and its successors) and one other nationally
recognized investment banking firm that is a primary U.S. Government securities
dealer specified from time to time by the Company. If, however, any of them
shall cease to be a primary U.S. Government securities dealer in New York City,
the Company will substitute another nationally recognized investment banking
firm that is such a dealer.

                  "Reference Treasury Dealer Quotations" means, with respect to
each Reference Treasury Dealer and any Redemption Date, the average, as
determined by the trustee, of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the trustee by such Reference Treasury Dealer as of 3:30
p.m., New York time, on the third Business Day preceding the Redemption Date.

                  "Remaining Scheduled Payments" means the remaining scheduled
payments of the principal of and interest on each Fixed Rate Note to be redeemed
that would be due after the related Redemption Date but for such redemption. If
the Redemption Date is not an Interest Payment Date with respect to the Fixed
Rate Note being redeemed, the amount of the next succeeding scheduled interest
payment on the Fixed Rate Note will be reduced by the amount of interest accrued
thereon to that Redemption Date.

pursuant to a Purchase Agreement, dated October 14, 2003, among the Company,
Citigroup Global Markets Inc., Goldman, Sachs & Co., J.P. Morgan Securities Inc.
and the other initial purchasers named therein. The Initial Notes and any
Additional Notes (if issued with transfer restrictions) (the "Restricted Notes")
will be resold initially only to (A) qualified institutional buyers (as defined
in Rule 144A under the Act ("Rule 144A")) in reliance on Rule 144A ("QIBs") and
(B) Persons other than U.S. Persons (as defined in Regulation S under the Act
("Regulation S")) in reliance on Regulation S. Such Restricted Notes may
thereafter be transferred to, among others, QIBs, purchasers in reliance on
Regulation S and institutional "accredited investors" (as defined in Rules
501(a)(1), (2), (3) and (7) under the Securities Act) who are not QIBs ("IAIs")
in accordance with Rule 501 of the Securities Act in accordance with the
procedure described herein.

                  Restricted Notes offered and sold to qualified institutional

and authenticated by the Trustee as hereinafter provided. The Rule 144A
Securities may be represented by more than one certificate, if so required by
DTC's rules regarding the maximum principal amount to be represented by a single
certificate. The aggregate principal amount of the Rule 144A Securities may from
time to time be increased or decreased by adjustments made on the records of the
Trustee, as custodian for DTC or its nominee, as hereinafter provided.

                  Initial Notes and Additional Notes offered and sold outside
the United States of America (the "Regulation S Notes") in reliance on

interest coupons, substantially in the form of Exhibit A, with respect to
Floating Rate Notes, or Exhibit B, with respect to Fixed Rate Notes (the
"Regulation S Global Securities"), deposited with the Trustee, as custodian for
DTC, duly executed by the Company and authenticated by the Trustee as

principal

                                      -8-
<PAGE>

amount of the Regulation S Global Securities may from time to time be increased
or decreased by adjustments made on the records of the Trustee, as custodian for
DTC or its nominee, as hereinafter provided.

                  Each Regulation S Global Note will be deposited with, or on
behalf of, a custodian for DTC for credit to the respective accounts of the
purchasers (or to such other accounts as they may direct) on behalf of the
Euroclear S.A. N.V., as operator of the Euroclear System ("Euroclear") or
Clearstream Banking, societe anonyme ("Clearstream"). Prior to the 40th day
after the later of the commencement of the offering of the Notes and October 17,
2003 (such period through and including such 40th day, the "Restricted Period"),
interests in the Regulation S Temporary Global Notes may only be held through
Euroclear or Cedel (as indirect participants in DTC) unless exchanged for
interests in the Rule 144A Securities.

                  Initial Notes and Additional Notes resold to IAIs (the
"Institutional Accredited Investor Notes") in the United States of America shall
be issued in the form of a permanent Global Security, without interest coupons,
substantially in the form of Exhibit A, with respect to Floating Rate Notes, or
Exhibit B, with respect to Fixed Rate Notes (the "Institutional Accredited

upon receipt by the Trustee or its agent of a certificate substantially in the
form set forth in Exhibit E from the proposed transferee and, if requested by
the Company or the Trustee, the delivery of an opinion of counsel, certification
and/or other information satisfactory to each of them. The Institutional
Accredited Investor Global Note may be represented by more than one certificate,
if so required by DTC's rules regarding the maximum principal amount to be
represented by a single certificate. The aggregate principal amount of the
Institutional Accredited Investor Global Note may from time to time be increased
or decreased by adjustments made on the records of the Trustee, as custodian for
DTC or its nominee, as hereinafter provided.

                  Securities issued in exchange for interests in the Rule 144A
Notes, the Regulation S Notes and the Institutional Accredited Investor Notes
will be issued in the form of a permanent Global Security, without interest
coupons, substantially in the form of Exhibit A or Exhibit B, as appropriate,
and deposited with the Trustee as hereinafter provided (the "Exchange Global
Securities"). The Exchange Global Securities may be represented by more than one
certificate, if so required by DTC's rules regarding the maximum principal
amount to be represented by a single certificate.

                  Upon any sale or transfer of a Restricted Note (x) pursuant to
Rule 144, (y) pursuant to an effective registration statement under the
Securities Act or (z) pursuant to any other available exemption (other than Rule
144A) from the registration requirements of the Securities Act and as a result
of which, in the case of a Security transferred pursuant to this clause (z),
such Security shall cease to be a "restricted security" within the meaning of
Rule 144, the Trustee shall permit the beneficial owner thereof to transfer such
beneficial interest to a transferee who shall take such interest in the form of
a beneficial interest in an unrestricted Global Security and shall rescind any
restriction on transfer of such beneficial interest; provided, however, that the
owner of such beneficial interest shall, in connection with such transfer,
comply with the other applicable provisions of this Article III.

do not have a Assignment Form attached thereto.

                  The Securities may have notations, legends or endorsements

owner of a beneficial interest in a Rule 144A Security to a transferee who takes
delivery of such interest through a Regulation S Global Note, whether before or
after the expiration of the Restricted Period, will be made only upon receipt by
the Trustee of a certification from the transferor substantially in the form of
Exhibit D.

                  Prior to the expiration of the Restricted Period, transfers by
an owner of a beneficial interest in a Regulation S Global Note to a transferee
who takes delivery of such interest through the applicable Rule 144A Security

                               HALLIBURTON COMPANY

                              SENIOR NOTES DUE 2005

                  This Security is one of a duly authorized issue of Senior
Notes Due 2005 (the "Securities") of Halliburton Company, a Delaware corporation
(the "Issuer"). The Issuer issued the Securities under an Indenture dated as of
October 17, 2003 between the Issuer and the Trustee, as supplemented by the
First Supplemental Indenture dated as of October 17, 2003 (the "Indenture").
Capitalized terms used herein for which no definition is provided herein shall
have the meanings set forth in the Indenture.

         1.       Interest. The Issuer promises to pay interest on the principal
amount of this Security from October 17, 2003 until maturity. The Securities
shall bear interest at the Three-Month LIBOR Rate, as determined by the
Calculation Agent on each Interest Determination Date, plus 1.50%, for each
Interest Period, until paid or duly provided for. The Issuer will pay interest
quarterly on January 17, April 17, July 17 and October 17 of each year, or, if
any such day is not a Business Day, on the next succeeding Business Day;
provided that if there is no existing Default in the payment of interest, and if
this Security is authenticated between a record date referred to on the face
hereof and the next succeeding Interest Payment Date, interest shall accrue from
such next succeeding Interest Payment Date; provided, further, that the first
Interest Payment Date shall be January 17, 2003. Interest on the Securities will
accrue from the most recent Interest Payment Date on which interest has been
paid or, if no interest has been paid, from October 17, 2003. The Three-Month
LIBOR Rate will be reset quarterly on each Interest Determination Date. Interest
payments for the Securities shall be computed and paid on the basis of a 360-day
year and the actual number of days in each interest period.

         2.       Method of Payment. The Issuer will pay interest on the
Securities (except defaulted interest) to the Persons who are registered Holders
of Securities at the close of business on the record date next preceding the
Interest Payment Date, even if such Securities are canceled after such record
date and on or before such Interest Payment Date. The Holder must surrender this
Security to a Paying Agent to collect principal payments. The Issuer will pay
the principal of and interest on the Securities in money of the United States of
America that at the time of payment is legal tender for payment of public and
private debts. Such amounts shall be payable at the offices of the Trustee or
any Paying Agent, provided that at the option of the Issuer, the Issuer may pay
such amounts (1) by wire transfer with respect to Securities represented by a
Global Note or (2) by check payable in such money mailed to a Holder's
registered address with respect to any Securities.

         3.       Paying Agent, Calculation Agent and Registrar. Initially,
JPMorgan Chase Bank (the "Trustee"), the Trustee under the Indenture, will act
as Paying Agent and Registrar and J.P. Morgan Securities Inc. will act as
Calculation Agent. The Issuer may change any Paying Agent, Calculation Agent,
Registrar, co-registrar, additional paying agent or calculation agent without
notice to any Holder. The Issuer or any of the Issuer's subsidiaries may act in
any such capacity.

         4.       Indenture. The terms of the Securities include those stated in
the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code ss.ss. 77aaa-77bbbb) (the
"TIA"), as in effect on the date of execution of the Indenture.

<PAGE>

The Securities are subject to all such terms, and Holders are referred to the
Indenture and the TIA for a statement of such terms. The Securities are
unsecured senior obligations of the Issuer and rank equally with all of the
Issuer's existing and future unsecured indebtedness. The Indenture provides for
the issuance of other series of debt securities thereunder.

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

         6.       Persons Deemed Owners. The registered Holder of a Security
shall be treated as its owner for all purposes.

         7.       Amendments and Waivers. Subject to certain exceptions and
limitations, the Indenture or the Securities may be amended or supplemented by
the Issuer and the Trustee with the written consent (including consents obtained
in connection with a tender offer or exchange offer for the Securities of any
one or more series or all series or a solicitation of consents in respect of the
Securities of any one or more series or all series, provided that in each case
such offer or solicitation is made to all Holders of then outstanding Securities
of each series (but the terms of such solicitation may vary from series to
series)) of the Holders of at least a majority in principal amount of the then
outstanding Securities of all series under the Indenture affected by such
amendment or supplement (acting as one class), and any existing or past Default

may be waived (other than any continuing Default or Event of Default in the
payment of the principal of, premium (if any) or interest on the Securities) by
the Holders of at least a majority in principal amount of the then outstanding
Securities of any series or of all series (acting as one class) in accordance
with the terms of the Indenture. The Issuer and the Trustee may amend or
supplement the Indenture or the Securities or waive any provision of either, to:

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

                  (2)      evidence the assumption by a Successor of the

         the Holders of the Securities, or to surrender any right or power

                  (7)      add any additional Events of Default with respect to
         the Securities;

                  (8)      change or eliminate any of the provisions of the
         Indenture, provided that any such change or elimination shall become
         effective only when there are no outstanding Securities of any series
         that are adversely affected in any material respect by such changes in
         or elimination of such provisions;

                  (9)      establish the form or terms of securities of any
         series as permitted by the Indenture;

         such extent as shall be necessary to permit or facilitate the
         defeasance and discharge of the Securities pursuant to the Indenture,
         provided that any such action shall not adversely affect the interest
         of the Holders of the Securities of any series in any material respect;

         Indenture as shall be necessary to provide for or facilitate the
         administration of the trusts thereunder by more than one Trustee,
         pursuant to the requirements of the Indenture; or

                  (12)     make any other change that does not adversely affect
         the rights of any Holder of any series of Securities under the
         Indenture.

                  The right of any Holder to participate in any consent required
or sought pursuant to any provision of the Indenture (and the obligation of the
Issuer to obtain any such consent otherwise required from such Holder) may be
subject to the requirement that such Holder shall have been the Holder of record
of any Securities with respect to which such consent is required or sought as of
a date fixed in accordance with the terms of the Indenture.

         Without the consent of each Holder affected, the Issuer may not:

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

                  (2)      reduce the rate of or change the time for payment of

         Indenture, except as limited by Section 6.06 of the Indenture;

                  (6)      make any change in the percentage of principal amount
         of Securities necessary to waive compliance with certain provisions of
         the Indenture pursuant to

         9.02(8) of the Indenture; or

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

                  A supplemental indenture that changes or eliminates any
covenant or other provision of the Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities under the
Indenture, or which modifies the rights of the Holders of Securities of such
series with respect to such covenant or other provision, shall be deemed not to
affect the rights under the Indenture of the Holders of the Securities.

         8.       Defaults and Remedies. Events of Default are defined in the
Indenture and with respect to the Securities generally include:

                  (1)      default by the Issuer in the payment of any interest
         on the Securities when the same becomes due and payable and such
         default continues for a period of 30 days;

                  (2)      default by the Issuer in any payment of principal of
         or premium (if any) on the Securities when the same becomes due and
         payable;

                  (3)      default by the Issuer in observing or performing any
         of its other covenants or agreements in, or provisions of, the
         Securities or the Indenture which shall not have been remedied within
         60 days after written notice to the Issuer by the Trustee or to the
         Issuer and Trustee by the holders of at least 25% in aggregate
         principal amount of the Securities then outstanding affected by such
         default;

                  (4)      default by the Issuer on a scheduled payment at
         maturity, in the aggregate principal amount of $125 million or more,
         after the expiration of any applicable grace period, of any
         Indebtedness or the acceleration of any Indebtedness of the Issuer in
         such aggregate principal amount, so that it becomes due and payable
         prior to the date on which it would otherwise have become due and
         payable and such payment default is not cured or such acceleration is
         not rescinded within 30 days after notice to the Issuer in accordance
         with the terms of the Indebtedness; or

                  (5)      certain events involving bankruptcy, insolvency or
         reorganization affecting the Issuer.

                  If an Event of Default occurs and is continuing, the Trustee
or the Holders of at least 25% in aggregate principal amount of the outstanding
Securities affected by such default (or, in the case of an Event of Default
described in clause (5) above, if outstanding Securities of other series are
affected by such Default, then at least 25% in principal amount of the then
outstanding Securities so affected), may declare the principal of and interest
on all the Securities to be immediately due and payable, except that in the case
of an Event of Default arising from certain events of bankruptcy, insolvency or
reorganization affecting the Issuer, all outstanding Securities become due and
payable immediately without further action or notice by the Trustee or any
Holder. The amount due and payable upon the acceleration of any Security is
equal to 100% of the principal amount thereof plus accrued interest to the date
of payment. Holders may not enforce the Indenture or the Securities except as
provided in the Indenture. The Trustee may

<PAGE>

require indemnity satisfactory to it before it enforces the Indenture or the
Securities. Subject to certain limitations, Holders of a majority in aggregate
principal amount of the then outstanding Securities may direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee,
or may direct the Trustee in its exercise of any trust or power conferred on the
Trustee. The Trustee may withhold from Holders notice of any continuing default
(except a default in payment of principal or interest) if it determines that
withholding notice is in their interests. The Issuer must furnish an annual
compliance certificate to the Trustee.

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

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

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

         12.      Authentication. The Securities shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

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

         14.      Indenture to Control; Governing Law. In the case of any
conflict between the provisions of this Security and the Indenture, the
provisions of the Indenture shall control. The Indenture and the Securities
shall be governed by and construed under the laws of the State of New York,
without giving effect to applicable principles of conflicts of law to the extent
the laws of another jurisdiction would be required to apply.

         15.      Successor Person. When a Successor assumes all the obligations
of its predecessor under the Securities and the Indenture in accordance with the
terms and conditions of the Indenture, the predecessor person will (except in
certain circumstances specified in the Indenture) be released from those
obligations.

         16.      Abbreviations and Definitions. Customary abbreviations may be
used in the name of a Holder or an assignee, such as: TEN COM (= tenants in
common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with
right of survivorship and not as tenants in common), CUST (= Custodian), and

                              [REVERSE OF SECURITY]

                               HALLIBURTON COMPANY

                          5 1/2 % Senior Notes due 2010

                  This Security is one of a duly authorized issue of 5 1/2%
Senior Notes Due 2010 (the "Securities") of Halliburton Company, a Delaware
corporation (the "Issuer"). The Issuer issued the Securities under an Indenture
dated as of October 17, 2003 between the Issuer and the Trustee, as supplemented
by the First Supplemental Indenture dated as of October 17, 2003 (the
"Indenture"). Capitalized terms used herein for which no definition is provided
herein shall have the meanings set forth in the Indenture.

         1.       Interest. The Issuer promises to pay interest on the principal
amount of this Security at 5 1/2% per annum from _______, 200_ until maturity.
The Issuer will pay interest semiannually on April 15 and October 15 of each
year, or if any such day is not a Business Day, on the next succeeding Business
Day. Interest on the Securities will accrue from the most recent Interest
Payment Date on which interest has been paid or, if no interest has been paid,
from _______, 200_; provided that if there is no existing Default in the payment
of interest, and if this Security is authenticated between a record date
referred to on the face hereof and the next succeeding Interest Payment Date,
interest shall accrue from such next succeeding Interest Payment Date; provided,
further, that the first Interest Payment Date shall be _______. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

         2.       Method of Payment. The Issuer will pay interest on the
Securities (except defaulted interest) to the Persons who are registered Holders
of Securities at the close of business on the record date next preceding the
Interest Payment Date, even if such Securities are canceled after such record
date and on or before such Interest Payment Date. The Holder must surrender this
Security to a Paying Agent to collect principal payments. The Issuer will pay
the principal of and interest on the Securities in money of the United States of
America that at the time of payment is legal tender for payment of public and
private debts. Such amounts shall be payable at the offices of the Trustee or
any Paying Agent, provided that at the option of the Issuer, the Issuer may pay
such amounts (1) by wire transfer with respect to Securities represented by a
Global Note or (2) by check payable in such money mailed to a Holder's
registered address with respect to any Security.

         3.       Paying Agent and Registrar. Initially, JPMorgan Chase Bank
(the "Trustee"), the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Issuer may change any Paying Agent, Registrar, co-registrar or
additional paying agent without notice to any Holder. The Issuer or any of the
Issuer's subsidiaries may act in any such capacity.

         4.       Indenture. The terms of the Securities include those stated in
the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code ss.ss. 77aaa-77bbbb) (the
"TIA"), as in effect on the date of execution of the Indenture. The Securities
are subject to all such terms, and Holders are referred to the Indenture and the
TIA for a statement of such terms. The Securities are unsecured senior
obligations of the Issuer and rank equally with all of the Issuer's existing and
future unsecured indebtedness. The Indenture provides for the issuance of other
series of debt securities thereunder.

<PAGE>

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

         6.       Redemption. No sinking fund is provided for the Securities. At
any time and from time to time the Securities will be redeemable, in the
Issuer's sole discretion, in whole or in part, in principal amounts of $1,000 or
any integral multiple of $1,000 for an amount equal to the greater of (i) 100%
of the principal amount of the Securities and (ii) as determined by an
Independent Investment Banker, the sum of the present values of the Remaining
Scheduled Payments on the Securities being redeemed, discounted to the
redemption date on a semiannual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Treasury Rate plus 25 basis points. In each case,
the Issuer will pay accrued interest to the date of redemption. In the event of
any such redemption, interest will accrue up to and including the date of
redemption. Unless there is a default in payment of the redemption amount, on
and after the Redemption Date, interest will cease to accrue on the Securities
or portions thereof called for redemption.

         7.       Persons Deemed Owners. The registered Holder of a Security
shall be treated as its owner for all purposes.

         8.       Amendments and Waivers. Subject to certain exceptions and
limitations, the Indenture or the Securities may be amended or supplemented by
the Issuer and the Trustee with the written consent (including consents obtained
in connection with a tender offer or exchange offer for the Securities of any
one or more series or all series or a solicitation of consents in respect of the
Securities of any one or more series or all series, provided that in each case
such offer or solicitation is made to all Holders of then outstanding Securities
of each series (but the terms of such solicitation may vary from series to
series)) of the Holders of at least a majority in principal amount of the then
outstanding Securities of all series under the Indenture affected by such
amendment or supplement (acting as one class), and any existing or past Default
or Event of Default under, or compliance with any provision of, the Indenture
may be waived (other than any continuing Default or Event of Default in the
payment of the principal of, premium (if any) or interest on the Securities) by
the Holders of at least a majority in principal amount of the then outstanding
Securities of any series or of all series (acting as one class) in accordance
with the terms of the Indenture. The Issuer and the Trustee may amend or
supplement the Indenture or the Securities or waive any provision of either, to:

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

                  (2)      evidence the assumption by a Successor of the

         guarantees of, or additional obligors on, the Securities;

                  (6)      add to the covenants of the Issuer for the benefit of
         the Holders of the Securities, or to surrender any right or power

                  (7)      add any additional Events of Default with respect to
         the Securities;

                  (8)      change or eliminate any of the provisions of the
         Indenture, provided that any such change or elimination shall become
         effective only when there are no outstanding Securities of any series
         that are adversely affected in any material respect by such changes in
         or elimination of such provisions;

                  (9)      establish the form or terms of securities of any
         series as permitted by the Indenture;

                  (10)     supplement any of the provisions of the Indenture to
         such extent as shall be necessary to permit or facilitate the
         defeasance and discharge of the Securities pursuant to the Indenture,
         provided that any such action shall not adversely affect the interest
         of the Holders of the Securities of any series in any material respect;

                  (11)     evidence and provide for the acceptance of
         appointment hereunder by a successor Trustee with respect to the
         Securities and to add to or change any of the provisions of this
         Indenture as shall be necessary to provide for or facilitate the
         administration of the trusts thereunder by more than one Trustee,
         pursuant to the requirements of the Indenture; or

                  (12)     make any other change that does not adversely affect
         the rights of any Holder of any series of Securities under the
         Indenture.

                  The right of any Holder to participate in any consent required
or sought pursuant to any provision of the Indenture (and the obligation of the
Issuer to obtain any such consent otherwise required from such Holder) may be
subject to the requirement that such Holder shall have been the Holder of record
of any Securities with respect to which such consent is required or sought as of
a date fixed in accordance with the terms of the Indenture.

                  Without the consent of each Holder affected, the Issuer may
not:

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

                  (2)      reduce the rate of or change the time for payment of

         enforcement of any payment of principal of, premium (if any) or
         interest on any Security pursuant to Sections 6.07 and 6.08 of the
         Indenture, except as limited by Section 6.06 of the Indenture;

                  (6)      make any change in the percentage of principal amount
         of Securities necessary to waive compliance with certain provisions of
         the Indenture pursuant to Section 6.04 or 6.07 of the Indenture or make
         any change in Section 9.02(8) of the Indenture; or

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

                  A supplemental indenture that changes or eliminates any
covenant or other provision of the Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities under the
Indenture, or which modifies the rights of the Holders of Securities of such
series with respect to such covenant or other provision, shall be deemed not to
affect the rights under the Indenture of the Holders of the Securities.

         9.       Defaults and Remedies. Events of Default are defined in the
Indenture and with respect to the Securities generally include:

                  (1)      default by the Issuer in the payment of any interest
         on the Securities when the same becomes due and payable and such
         default continues for a period of 30 days;

                  (2)      default by the Issuer in any payment of principal of
         or premium (if any) on the Securities when the same becomes due and
         payable;

                  (3)      default by the Issuer in observing or performing any
         of its other covenants or agreements in, or provisions of, the
         Securities or the Indenture which shall not have been remedied within
         60 days after written notice to the Issuer by the Trustee or to the
         Issuer and Trustee by the holders of at least 25% in aggregate
         principal amount of the Securities then outstanding affected by such
         default;

                  (4)      default by the Issuer on a scheduled payment at
         maturity, in the aggregate principal amount of $125 million or more,
         after the expiration of any applicable grace period, of any
         Indebtedness or the acceleration of any Indebtedness of the Issuer in
         such aggregate principal amount, so that it becomes due and payable
         prior to the date on which it would otherwise have become due and
         payable and such payment default is not cured or such acceleration is
         not rescinded within 30 days after notice to the Issuer in accordance
         with the terms of the Indebtedness; or

                  (5)      certain events involving bankruptcy, insolvency or
         reorganization affecting the Issuer.

                  If an Event of Default occurs and is continuing, the Trustee
or the Holders of at least 25% in aggregate principal amount of the outstanding
Securities affected by such default (or, in the case of an Event of Default
described in clause (5) above, if outstanding Securities of other series are
affected by such Default, then at least 25% in principal amount of the then
outstanding Securities so affected), may declare the principal of and interest
on all the Securities

<PAGE>

to be immediately due and payable, except that in the case of an Event of
Default arising from certain events of bankruptcy, insolvency or reorganization
affecting the Issuer, all outstanding Securities become due and payable
immediately without further action or notice by the Trustee or any Holder. The
amount due and payable upon the acceleration of any Security is equal to 100% of
the principal amount thereof plus accrued interest to the date of payment.
Holders may not enforce the Indenture or the Securities except as provided in
the Indenture. The Trustee may require indemnity satisfactory to it before it
enforces the Indenture or the Securities. Subject to certain limitations,
Holders of a majority in aggregate principal amount of the then outstanding
Securities may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or may direct the Trustee in its
exercise of any trust or power conferred on the Trustee. The Trustee may
withhold from Holders notice of any continuing default (except a default in
payment of principal or interest) if it determines that withholding notice is in
their interests. The Issuer must furnish an annual compliance certificate to the
Trustee.

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

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

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

         13.      Authentication. The Securities shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

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

         15.      Indenture to Control; Governing Law. In the case of any
conflict between the provisions of this Security and the Indenture, the
provisions of the Indenture shall control. The Indenture and the Securities
shall be governed by and construed under the laws of the State of New York,
without giving effect to applicable principles of conflicts of law to the extent
the laws of another jurisdiction would be required to apply.

         16.      Successor Person. When a Successor assumes all the obligations
of its predecessor under the Securities and the Indenture in accordance with the
terms and conditions of the Indenture, the predecessor person will (except in
certain circumstances specified in the Indenture) be released from those
obligations.

Dear Sir or Madam:

aggregate principal amount of the Notes, we confirm that such sale has been
effected pursuant to and in accordance with Regulation S under the United States
Securities Act of 1933, as amended (the "Securities Act"), and, accordingly, we
represent that:

the United States;

                  (b)      either (i) at the time the buy order was originated,
the transferee was outside the United States or we and any person acting on our
behalf reasonably believed that the transferee was outside the United States or

designated off-shore securities market and neither we nor any person acting on
our behalf knows that the transaction has been pre-arranged with a buyer in the
United States;

                  (c)      no directed selling efforts have been made in the
United States in contravention of the requirements of Rule 903(b) or Rule 904(b)
of Regulation S, as applicable;

                  (d)      the transaction is not part of a plan or scheme to
evade the registration requirements of the Securities Act; and

                  (e)      we are the beneficial owner of the principal amount
of Notes being transferred.

                  In addition, if the sale is made during a restricted period
and the provisions of Rule 903(c)(3) or Rule 904(c)(1) of Regulation S are
applicable thereto, we confirm that such sale has been made in accordance with
the applicable provisions of Rule 903(c)(3) or Rule 904(c)(1), as the case may
be.

Halliburton Company
c/o JPMorgan Chase Bank

Attention:  Institutional Trust Services

Ladies and Gentlemen:

                  This certificate is delivered to request a transfer of
$__________ principal amount of the [5 1/2% Senior Notes due October 15, 2010
(the "Notes")][Senior Notes due October 17, 2005] of Halliburton Company (the
"Company").

                  Upon transfer, the Notes would be registered in the name of
the new beneficial owner as follows:

                  Name: ____________________________________

                  Address: __________________________________

                  Taxpayer ID Number: ________________________

                  The undersigned represents and warrants to you that:

                  1.       We are an institutional accredited investor (as
defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as
amended (the "Securities Act")) purchasing for our own account or for the
account of such an institutional accredited investor at least $250,000 principal
amount of the Notes, and we are acquiring the Notes not with a view to, or for
offer or sale in connection with, any distribution in violation of the
Securities Act. We have such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risk of our investment in
the Notes and we invest in or purchase securities similar to the Notes in the
normal course of our business. We and any accounts for which we are acting are
each able to bear the economic risk of our or its investment.

                  2.       We understand that the Notes have not been registered
under the Securities Act and, unless so registered, may not be sold except as
permitted in the following sentence. We agree on our own behalf and on behalf of
any investor account for which we are purchasing Notes to offer, sell or
otherwise transfer such Notes prior to the date that is two years after the
later of the date of original issue and the last date on which the Company or
any affiliate of the Company was the owner of such Notes (or any predecessor
thereto) (the "Resale Restriction Termination Date") only (a) to the Company,
(b) pursuant to a registration statement

                                      E-1
<PAGE>

which has been declared effective under the Securities Act, (c) in a transaction
complying with the requirements of Rule 144A under the Securities Act ("Rule
144A"), to a person we reasonably believe is a qualified institutional buyer
under Rule 144A (a "QIB") that purchases for its own account or for the account
of a QIB and to whom notice is given that the transfer is being made in reliance
on Rule 144A, (d) pursuant to offers and sales that occur outside the United
States within the meaning of Regulation S under the Securities Act, (e) to an
institutional accredited investor within the meaning of Rule 501(a)(1), (2), (3)
or (7) under the Securities Act that is purchasing for its own account or for
the account of such an institutional accredited investor, in each case in a
minimum principal amount of Notes of $250,000 or (f) pursuant to any other
available exemption from the registration requirements of the Securities Act,
subject in each of the foregoing cases to any requirement of law that the
disposition of our property or the property of such investor account or accounts
be at all times within our or their control and in compliance with any
applicable state securities laws. The foregoing restrictions on resale will not
apply subsequent to the Resale Restriction Termination Date. If any resale or
other transfer of the Notes is proposed to be made pursuant to clause (e) above
prior to the Resale Restriction Termination Date, the transferor shall deliver a
letter from the transferee substantially in the form of this letter to the
Company and the Trustee, which shall provide, among other things, that the
transferee is an institutional accredited investor (within the meaning of Rule
501(a)(1), (2), (3) or (7) under the Securities Act) and that it is acquiring
such Notes for investment purposes and not for distribution in violation of the
Securities Act. Each purchaser acknowledges that the Company and the Trustee
reserve the right prior to any offer, sale or other transfer prior to the Resale
Termination Date of the Notes pursuant to clause (d), (e) or (f) above to
require the delivery of an opinion of counsel, certifications and/or other
information satisfactory to the Company and the Trustee.
