and the Coupons, if any, to be attached thereto shall be substantially in such
form (not inconsistent with this Indenture) as shall be established by or
pursuant to one or more Board Resolutions (as set forth in a Board Resolution
or, to the extent





                                       8

established pursuant to rather than set forth in a Board Resolution, an
Officers' Certificate detailing such establishment) or in one or more
indentures supplemental hereto, in each case with such appropriate insertions,
omissions, substitutions and other variations as are required or permitted by
this Indenture and may have imprinted or otherwise reproduced thereon such
legend or legends or endorsements, not inconsistent with the provisions of this
Indenture, as may be required to comply with any law or with any rules or
regulations pursuant thereto, or with any rules of any securities exchange or
to conform to general usage, all as may be determined by the officers executing
such Securities and Coupons, if any, as evidenced by their execution of such
Securities and Coupons.

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 and Coupons, if any, as evidenced by their execution of such
Securities and Coupons, if any.

aggregate principal amount of Securities which may be authenticated and
delivered under this Indenture is unlimited.

                 The Securities may be issued in one or more series, and each
such series shall rank equally and pari passu with all other unsecured and
unsubordinated debt of the Issuer.  There shall be established in or pursuant
to one or more Board Resolutions (and, to the extent established pursuant to
rather than set forth in a Board Resolution, in an Officers' Certificate
detailing such establishment) or established in one or more indentures

         registration of transfer of, or in exchange for, or in lieu of, other
         Securities of the series pursuant to Section 2.8, 2.9, 2.11, 7.5 or
         11.3);

                 (3)  if other than Dollars, the coin or currency in which the

         shall bear interest, if any, the date or dates from which such
         interest shall accrue, on which such interest shall be payable and (in
         the case of Registered Securities) on which a record shall be taken
         for the determination of Holders to whom interest is payable and/or
         the method by which such rate or rates or date or dates shall be
         determined;

                 (6)  the place or places where the principal of and any
         interest on Securities of the series shall be payable (if

   17
         other than as provided in Section 3.2);

                 (7)  the right, if any, of the Issuer to redeem Securities, in
         whole or in part, at its option and the period or periods within
         which, the price or prices at which and any terms and conditions upon
         which Securities of the series may be so redeemed, pursuant to any
         sinking fund or otherwise;

                 (8)  the obligation, if any, of the Issuer to redeem,
         repurchase or repay Securities of the series pursuant to any mandatory
         redemption, sinking fund or analogous provisions or at the option of a
         Holder thereof and the price or prices at which and the period or
         periods within which and any terms and conditions upon which
         Securities of the series shall be redeemed, repurchased or repaid, in
         whole or in part, pursuant to such obligation;

                 (9)  if other than denominations of $1,000 and any integral
         multiple thereof in the case of Registered Securities, or $1,000 and
         $5,000 in the case of Unregistered Securities, the denominations in
         which Securities of the series shall be issuable;

                 (10)  if other than the principal amount thereof, the portion
         of the principal amount of Securities of the series which shall be
         payable upon declaration of acceleration of the maturity thereof;

                 (11)  if other than the coin or currency in which the
         Securities of that series are denominated, the coin or currency in
         which payment of the principal of or interest on the Securities of
         such series shall be payable;

                 (12)  if the principal of or interest on the Securities of
         such series are to be payable, at the election of the Issuer or a
         Holder thereof, in a coin or currency other than that in which the
         Securities are denominated, the period or periods within which, and
         the terms and conditions upon which, such election may be made;

                 (13)  if the amount of payments of principal of and interest
         on the Securities of the series may be determined with reference to an
         index based on a coin or currency other than that in which the
         Securities of the series are denominated, the manner in which such
         amounts shall be determined;

                 (14)  whether the Securities of the series will be issuable as
         Registered Securities (and if so, whether such Securities will be
         issuable as Registered Global Securities)





                                       11
   18
         or Unregistered Securities (with or without Coupons), or any
         combination of the foregoing, any restrictions applicable to the
         offer, sale or delivery of Unregistered Securities or the payment of
         interest thereon and, if other than as provided in Section 2.8, the
         terms upon which Unregistered Securities of any series may be
         exchanged for Registered Securities of such series and vice versa;

                 (15)  whether and under what circumstances the Issuer will pay
         additional amounts on the Securities of the series held by a Person
         who is not a U.S. Person in respect of any tax, assessment or
         governmental charge withheld or deducted and, if so, whether the
         Issuer will have the option to redeem such Securities rather than pay
         such additional amounts;

                 (16)  if the Securities of such series are to be issuable in
         definitive form (whether upon original issue or upon exchange of a
         temporary Security of such series) only upon receipt of certain
         certificates or other documents or satisfaction of other conditions,
         the form and terms of such certificates, documents or conditions;

                 (17)  any trustees, depositaries, authenticating or paying
         agents, transfer agents or registrars or any other agents with respect
         to the Securities of such series;

                 (18)  any other Events of Default or covenants with respect to
         the Securities of such series; and

                 (19)  any other terms of the series (which terms shall not be
         inconsistent with the provisions of this Indenture).

                 All Securities of any one series and Coupons, if any,
appertaining thereto, shall be substantially identical, except in the case of
Registered Securities as to denomination and except as may otherwise be
provided by or pursuant to the Board Resolution or Officers' Certificate
referred to above or as set forth in any such indenture supplemental hereto.
All Securities of any one series need not be issued at the same time and may be
issued from time to time, consistent with the terms of this Indenture, if so
provided by or pursuant to such Board Resolution, such Officers' Certificate or
in any such indenture supplemental hereto.

                 SECTION 2.4  Authentication and Delivery of Securities.  The
Issuer may deliver Securities of any series having attached thereto appropriate
Coupons, if any, executed by the Issuer to the Trustee for authentication
together with the applicable documents referred to below in this Section, and
the Trustee shall thereupon authenticate and deliver such Securities to or upon
the order of the Issuer (contained in the Issuer Order referred to below in
this





                                       12
   19
Section) or pursuant to such procedures acceptable to the Trustee and to such
recipients as may be specified from time to time by an Issuer Order.  The
maturity date, original issue date, interest rate and any other terms of the
Securities of such series and Coupons, if any, appertaining thereto shall be
specified in or pursuant to such Issuer Order and procedures.  If provided for
in such procedures, such Issuer Order may authorize authentication and delivery
pursuant to oral instructions from the Issuer or its duly authorized agent,
which instructions shall be promptly confirmed in writing.  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 the case of subparagraphs 2, 3 and 4 below only at or before the
time of the first request of the Issuer to the Trustee to authenticate
Securities of such series) and (subject to Section 5.1) shall be fully
protected in relying upon, unless and until such documents have been superceded
or revoked:

                 (1)  an Issuer Order requesting such authentication and
         setting forth delivery instructions if the Securities and Coupons, if
         any, are not to be delivered to the Issuer, provided that, with
         respect to Securities of a series subject to a Periodic Offering, (a)
         such Issuer Order may be delivered by the Issuer to the Trustee prior
         to the delivery to the Trustee of such Securities for authentication
         and delivery, (b) the Trustee shall authenticate and deliver
         Securities of such series for original issue from time to time, in an
         aggregate principal amount not exceeding the aggregate principal
         amount established for such series, pursuant to an Issuer Order or
         pursuant to procedures acceptable to the Trustee as may be specified
         from time to time by an Issuer Order, (c) the maturity date or dates,
         original issue date or dates, interest rate or rates and any other
         terms of Securities of such series shall be determined by an Issuer
         Order or pursuant to such procedures and (d) if provided for in such
         procedures, such Issuer Order may authorize authentication and
         delivery pursuant to oral or electronic instructions from the Issuer
         or its duly authorized agent or agents, which oral instructions shall
         be promptly confirmed in writing;

                 (2)  any Board Resolution, Officers' Certificate and/or
         executed supplemental indenture referred to in Sections 2.1 and 2.3 by
         or pursuant to which the forms and terms of the Securities and
         Coupons, if any, were established;

                 (3)  an Officers' Certificate setting forth the form or forms
         and terms of the Securities and Coupons, if any, stating that the form
         or forms and terms of the Securities and Coupons, if any, have been
         established pursuant to Sections





                                       13
   20
         2.1 and 2.3 and comply with this Indenture, and covering such other
         matters as the Trustee may reasonably request; and

                 (4)  at the option of the Issuer, either an Opinion of
         Counsel, or a letter addressed to the Trustee permitting to it to rely
         on an Opinion of Counsel, substantially to the effect that:

                          (a)  the forms of the Securities and Coupons, if any,
                 have been duly authorized and established in conformity with
                 the provisions of this Indenture;

                          (b)  in the case of an underwritten offering, the
                 terms of the Securities have been duly authorized and
                 established in conformity with the provisions of this
                 Indenture, and, in the case of an offering that is not
                 underwritten, certain terms of the Securities have been
                 established pursuant to a Board Resolution, an Officers'
                 Certificate or a supplemental indenture in accordance with
                 this Indenture, and when such other terms as are to be
                 established pursuant to procedures set forth in an Issuer
                 Order shall have been established, all such terms will have
                 been duly authorized by the Issuer and will have been
                 established in conformity with the provisions of this
                 Indenture;

                          (c)  when the Securities and Coupons, if any, have
                 been executed by the Issuer and authenticated by the Trustee
                 in accordance with the provisions of this Indenture and
                 delivered to and duly paid for by the purchasers thereof, they
                 will have been duly issued under this Indenture and will be
                 valid and legally binding obligations of the Issuer,
                 enforceable in accordance with their respective terms, and
                 will be entitled to the benefits of this Indenture; and

                          (d)  the execution and delivery by the Issuer of, and
                 the performance by the Issuer of its obligations under, the
                 Securities and Coupons, if any, will not contravene any
                 provision of applicable law or the certificate of
                 incorporation or by-laws of the Issuer or any agreement or
                 other instrument binding upon the Issuer or any of its
                 Subsidiaries that is material to the Issuer and its
                 Subsidiaries, considered as one enterprise, or, to the best of
                 such counsel's knowledge, any judgment, order or decree of any
                 governmental body, agency or court having jurisdiction over
                 the Issuer or any Subsidiary, and no consent, approval or
                 authorization of any governmental body or agency is required
                 for the performance by the Issuer of its obligations under the





                                       14
   21
                 Securities and Coupons, if any, except such as are specified
                 and have been obtained and such as may be required by the
                 securities or blue sky laws of the various states in
                 connection with the offer and sale of the Securities.

                 In rendering such opinions, such counsel may qualify any
opinions as to enforceability by stating that such enforceability may be
limited by bankruptcy, insolvency, reorganization, liquidation, moratorium and
other similar laws affecting the rights and remedies of creditors and is
subject to general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).  Such
counsel may rely, as to all matters governed by the laws of jurisdictions other
than the State of New York and the federal law of the United States, upon
opinions of other counsel (copies of which shall be delivered to the Trustee),
in which case the opinion shall state that such counsel believes he and the
Trustee are entitled so to rely.  Such counsel may also state that, insofar as
such opinion involves factual matters, he has relied, to the extent he deems
proper, upon certificates of officers of the Issuer and its subsidiaries and
certificates of public officials.

                 The Trustee shall have the right to decline to authenticate
and deliver any Securities under this Section if the Trustee, being advised by
counsel, determines that such action may not lawfully be taken by the Issuer or
if the Trustee in good faith by its board of directors or board of trustees,
executive committee, or a trust committee of directors or trustees or
Responsible Officers shall determine that such action would expose the Trustee
to personal liability to existing Holders or would affect the Trustee's own
rights, duties or immunities under the Securities, this Indenture or otherwise.

                 If the Issuer shall establish pursuant to Section 2.3 that the
Securities of a series are to be issued in the form of one or more Registered
Global Securities, then the Issuer shall execute and the Trustee shall, in
accordance with this Section and the Issuer Order with respect to such series,
authenticate and deliver one or more Registered Global Securities that (i)
shall represent and shall be denominated in an amount equal to all or part of
the aggregate principal amount of the Securities of such series issued and not
yet cancelled, (ii) shall be registered in the name of the Depositary for such
Registered Global Security or Securities or the nominee of such Depositary,
(iii) shall be delivered by the Trustee to such Depositary or pursuant to such
Depositary's instructions and (iv) shall bear a legend substantially to the
following effect:  "Unless and until it is exchanged in whole or in part for
Securities in definitive registered form, this Security may not be transferred
except as a whole by the Depositary to the nominee of





                                       15
   22
the Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary."

                 Each Depositary must, at the time of its designation and at
all times while it serves as Depositary, be a clearing agency registered under
the Securities Exchange Act of 1934 and any other applicable statute or
regulation.

                 SECTION 2.5  Execution of Securities.  The Securities and, if
applicable, each Coupon appertaining thereto shall be signed on behalf of the
Issuer by its Chairman of the Board, its President or one of its Vice
Presidents, under its corporate seal (except in the case of Coupons) which may,
but need not, be attested.  Such signatures may be the manual or facsimile
signatures of the present or any future such officers.  The seal of the Issuer
may be in the form of a facsimile thereof and may be impressed, affixed,
imprinted or otherwise reproduced on the Securities.  Typographical and other
minor errors or defects in any such reproduction of the seal or any such
signature shall not affect the validity or enforceability of any Security that
has been duly authenticated and delivered by the Trustee.

                 In case any officer of the Issuer who shall have signed any of
the Securities or Coupons, if any, shall cease to be such officer before the
Security or Coupon so signed (or the Security to which the Coupon so signed
appertains) shall be authenticated and delivered by the Trustee or disposed of
by the Issuer, such Security or Coupon nevertheless may be authenticated and
delivered or disposed of as though the person who signed such Security or
Coupon had not ceased to be such officer of the Issuer; and any Security or
Coupon may be signed on behalf of the Issuer by such persons as, at the actual
date of the execution of such Security or Coupon, shall be the proper officers
of the Issuer, although at the date of the execution and delivery of this
Indenture any such person was not such an officer.

                 SECTION 2.6  Certificate of Authentication.  Only such
Securities as shall bear thereon a certificate of authentication substantially
in the form hereinbefore recited, executed by the Trustee by the manual
signature of one of its authorized officers, shall be entitled to the benefits
of this Indenture or be valid or obligatory for any purpose.  No Coupon shall
be entitled to the benefits of this Indenture or shall be valid and obligatory
for any purpose until the certificate of authentication on the Security to
which such Coupon appertains shall have been duly executed by the Trustee.  The
execution of such certificate by the Trustee upon any Security executed by the
Issuer shall be conclusive evidence that the Security so authenticated has been
duly authenticated and





                                       16
   23
delivered hereunder and that the Holder is entitled to the benefits of this
Indenture.

                 SECTION 2.7  Denomination and Date of Securities; Payments of
Interest.  The Securities of each series shall be issuable as Registered
Securities or Unregistered Securities in denominations established as
contemplated by Section 2.3 or, with respect to the Registered Securities of
any series, if not so established, in denominations of $1,000 and any integral
multiple thereof.  If denominations of Unregistered Securities of any series
are not so established, such Securities shall be issuable in denominations of
$1,000 and $5,000.  The Securities of each series shall be numbered, lettered
or otherwise distinguished in such manner or in accordance with such plan as
the officers of the Issuer executing the same may determine with the approval
of the Trustee, as evidenced by the execution and authentication thereof.

                 Each Registered Security shall be dated the date of its
authentication.  Each Unregistered Security shall be dated as provided in or
pursuant to the resolution or resolutions of the Board of Directors of the
Issuer referred to in Section 2.3.  The Securities of each series shall bear
interest, if any, from the date, and such interest shall be payable on the
dates, established as contemplated by Section 2.3.

                 Unless specifically otherwise provided in a Board Resolution,
Officers' Certificate or indenture supplemental hereto provided pursuant to
Section 2.3, the Person in whose name any Registered Security of any series is
registered at the close of business on any record date applicable to a
particular series with respect to any interest payment date for such series
shall be entitled to receive the interest, if any, payable on such interest
payment date notwithstanding any transfer or exchange of such Registered
Security subsequent to the record date and prior to such interest payment date,
except if and to the extent the Issuer shall default in the payment of the
interest due on such interest payment date for such series, in which case such
defaulted interest shall be paid to the Persons in whose names Outstanding
Registered Securities for such series are registered at the close of business
on a subsequent record date (which shall be not less than five Business Days
prior to the date of payment of such defaulted interest) established by notice
given by mail by or on behalf of the Issuer to the Holders of Registered
Securities not less than 15 days preceding such subsequent record date.  The
term "record date" as used with respect to any interest payment date (except a
date for payment of defaulted interest) for the Securities of any series shall
mean the date specified as such in the terms of the Registered Securities of
such series established as contemplated by Section 2.3, or, if no such date is
so established, if such interest payment date is the first day of a calendar
month, the





                                       17
   24
fifteenth day of the next preceding calendar month or, if such interest payment
date is the fifteenth day of a calendar month, the first day of such calendar
month, whether or not such record date is a Business Day.

                 SECTION 2.8  Registration, Transfer and Exchange.  The Issuer
will keep or cause to be kept at each office or agency to be maintained for the
purpose as provided in Section 3.2 for each series of Securities a register in
which, subject to such reasonable regulations as it may prescribe, it will
provide for the registration of Registered Securities of such series and the
registration of transfer of Registered Securities of such series.  Such
register shall be in written form in the English language or in any other form
capable of being converted into such form within a reasonable time.  At all
reasonable times such register or registers shall be open for inspection by the
Trustee.

                 Upon due presentation for registration of transfer of any
Registered Security of any series at any such office or agency to be maintained
for the purpose as provided in Section 3.2, the Issuer shall execute and the
Trustee shall authenticate and deliver in the name of the transferee or
transferees a new Registered Security or Registered Securities of the same
series, maturity date, interest rate and original issue date in authorized
denominations for a like aggregate principal amount.

                 Unregistered Securities (except for any temporary global
Unregistered Securities) and Coupons (except for Coupons attached to any
temporary global Unregistered Securities) shall be transferable by delivery.

                 At the option of the Holder thereof, Registered Securities of
any series (other than a Registered Global Security, except as set forth below)
may be exchanged for a Registered Security or Registered Securities of such
series having authorized denominations and an equal aggregate principal amount,
upon surrender of such Registered Securities to be exchanged at the agency of
the Issuer that shall be maintained for such purpose in accordance with Section
3.2 and upon payment, if the Issuer shall so require, of the charges
hereinafter provided.  If the Securities of any series are issued in both
registered and unregistered form, except as otherwise specified pursuant to
Section 2.3, at the option of the Holder thereof, Unregistered Securities of
any series may be exchanged for Registered Securities of such series having
authorized denominations and an equal aggregate principal amount, upon
surrender of such Unregistered Securities to be exchanged at the agency of the
Issuer that shall be maintained for such purpose in accordance with Section
3.2, with, in the case of Unregistered Securities that have Coupons attached,
all unmatured Coupons and all matured Coupons in default thereto appertaining,
and upon





                                       18
   25
payment, if the Issuer shall so require, of the charges hereinafter provided.
At the option of the Holder thereof, if Unregistered Securities of any series,
maturity date, interest rate and original issue date are issued in more than
one authorized denomination, except as otherwise specified pursuant to Section
2.3, such Unregistered Securities may be exchanged for Unregistered Securities
of such series, maturity date, interest rate and original issue date having
authorized denominations and an equal aggregate principal amount, upon
surrender of such Unregistered Securities to be exchanged at the agency of the
Issuer that shall be maintained for such purpose in accordance with Section 3.2
or as specified pursuant to Section 2.3, with, in the case of Unregistered
Securities that have Coupons attached, all unmatured Coupons and all matured
Coupons in default thereto appertaining, and upon payment, if the Issuer shall
so require, of the charges hereinafter provided.  Unless otherwise specified
pursuant to Section 2.3, Registered Securities of any series may not be
exchanged for Unregistered Securities of such series.  Whenever any Securities
are so surrendered for exchange, the Issuer shall execute, and the Trustee
shall authenticate and deliver, the Securities which the Holder making the
exchange is entitled to receive.  All Securities and Coupons surrendered upon
any exchange or transfer provided for in this Indenture shall be promptly
cancelled and disposed of by the Trustee and the Trustee will deliver a
certificate of disposition thereof to the Issuer.

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

                 The Issuer may require payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection with any
exchange or registration of transfer of Securities.  No service charge shall be
made for any such transaction.

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

                 Notwithstanding any other provision of this Section 2.8,
unless and until it is exchanged in whole or in part for Securities in
definitive registered form, a Registered Global Security





                                       19
   26
representing all or a portion of the Securities of a series may not be
transferred except as a whole by the Depositary for such series to a nominee of
such Depositary or by a nominee of such Depositary to such Depositary or
another nominee of such Depositary or by such Depositary or any such nominee to
a successor Depositary for such series or a nominee of such successor
Depositary.

                 If at any time the Depositary for any Registered Securities of
a series represented by one or more Registered Global Securities notifies the
Issuer that it is unwilling or unable to continue as Depositary for such
Registered Securities or if at any time the Depositary for such Registered
Securities shall no longer be eligible under Section 2.4, the Issuer shall
appoint a successor Depositary with respect to such Registered Securities.  If
a successor Depositary for such Registered Securities is not appointed by the
Issuer within 90 days after the Issuer receives such notice or becomes aware of
such ineligibility, the Issuer's election pursuant to Section 2.3 that such
Registered Securities be represented by one or more Registered Global
Securities shall no longer be effective and the Issuer will execute, and the
Trustee, upon receipt of an Officers' Certificate for the authentication and
delivery of definitive Securities of such series, will authenticate and
deliver, Securities of such series in definitive registered form without
Coupons, in any authorized denominations, in an aggregate principal amount
equal to the principal amount of the Registered Global Security or Securities
representing such Registered Securities in exchange for such Registered Global
Security or Securities.

                 The Issuer may at any time and in its sole discretion
determine that the Registered Securities of any series issued in the form of
one or more Registered Global Securities shall no longer be represented by a
Registered Global Security or Securities.  In such event the Issuer will
execute, and the Trustee, upon receipt of an Officers' Certificate for the
authentication and delivery of definitive Securities of such series, will
authenticate and deliver, Securities of such series in definitive registered
form without Coupons, in any authorized denominations, in an aggregate
principal amount equal to the principal amount of the Registered Global
Security or Securities representing such Registered Securities, in exchange for
such Registered Global Security or Securities.

                 If specified by the Issuer pursuant to Section 2.3 with
respect to Securities represented by a Registered Global Security, the
Depositary for such Registered Global Security may surrender such Registered
Global Security in exchange in whole or in part for Securities of the same
series in definitive registered form on such terms as are acceptable to the
Issuer and such Depositary.  Thereupon, the Issuer shall execute, and the
Trustee shall





                                       20
   27
authenticate and deliver, without service charge,

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

                 (ii)  to such Depositary a new Registered Global Security in a
         denomination equal to the difference, if any, between the principal
         amount of the surrendered Registered Global Security and the aggregate
         principal amount of Registered Securities authenticated and delivered
         pursuant to clause (i) above.

                 Upon the exchange of a Registered Global Security for
Securities in definitive registered form without Coupons, in authorized
denominations, such Registered Global Security shall be cancelled by the
Trustee or its agent.  Securities in definitive registered form without Coupons
issued in exchange for a Registered Global Security pursuant to this Section
2.8 shall be registered in such names and in such authorized denominations as
the Depositary for such Registered Global Security, pursuant to instructions
from its direct or indirect participants or otherwise, shall instruct the
Trustee or an agent of the Issuer or the Trustee.  The Trustee or such agent
shall deliver such Securities to or as directed by the Persons in whose names
such Securities are so registered.

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

                 Notwithstanding anything herein or in the terms of any series
of Securities to the contrary, none of the Issuer, the Trustee or any agent of
the Issuer or the Trustee (any of which, other than the Issuer, shall rely on
an Officers' Certificate and an Opinion of Counsel) shall be required to
exchange any Unregistered Security for a Registered Security if such exchange
would result in adverse Federal income tax consequences to the Issuer (such as,
for example, the inability of the Issuer to deduct from its income, as computed
for Federal income tax purposes, the interest payable on the Unregistered
Securities) under then applicable United States Federal income tax laws.

                 SECTION 2.9  Mutilated, Defaced, Destroyed, Lost and Stolen
Securities.  In case any temporary or definitive Security or any Coupon
appertaining to any Security shall become mutilated, defaced or be destroyed,
lost or stolen, the Issuer in its discretion may execute, and upon the written
request of any officer





                                       21
   28
of the Issuer, the Trustee shall authenticate and deliver a new Security of the
same series, maturity date, interest rate and original issue date, bearing a
number or other distinguishing symbol not contemporaneously outstanding, in
exchange and substitution for the mutilated or defaced Security, or in lieu of
and in substitution for the Security so destroyed, lost or stolen with Coupons
corresponding to the Coupons appertaining to the Securities so mutilated,
defaced, destroyed, lost or stolen, or in exchange or substitution for the
Security to which such mutilated, defaced, destroyed, lost or stolen Coupon
appertained, with Coupons appertaining thereto corresponding to the Coupons so
mutilated, defaced, destroyed, lost or stolen.  In every case the applicant for
a substitute Security or Coupon shall furnish to the Issuer and to the Trustee
and any agent of the Issuer or the Trustee such security or indemnity as may be
required by them to indemnify and defend and to save each of them harmless and,
in every case of destruction, loss or theft, evidence to their satisfaction of
the destruction, loss or theft of such Security or Coupon and of the ownership
thereof and in the case of mutilation or defacement shall surrender the
Security and related Coupons to the Trustee or such agent.

                 Upon the issuance of any substitute Security or Coupon, the
Issuer may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee or its agent)
connected therewith.  In case any Security or Coupon which has matured or is
about to mature or has been called for redemption in full shall become
mutilated or defaced or be destroyed, lost or stolen, the Issuer may instead of
issuing a substitute Security, pay or authorize the payment of the same or the
relevant Coupon (without surrender thereof except in the case of a mutilated or
defaced Security or Coupon), if the applicant for such payment shall furnish to
the Issuer and to the Trustee and any agent of the Issuer or the Trustee such
security or indemnity as any of them may require to save each of them harmless,
and, in every case of destruction, loss or theft, the applicant shall also
furnish to the Issuer and the Trustee and any agent of the Issuer or the
Trustee evidence to their satisfaction of the destruction, loss or theft of
such Security or Coupon and of the ownership thereof.

                 Every substitute Security or Coupon of any series issued
pursuant to the provisions of this Section by virtue of the fact that any such
Security or Coupon is destroyed, lost or stolen shall constitute an additional
contractual obligation of the Issuer, whether or not the destroyed, lost or
stolen Security or Coupon shall be at any time enforceable by anyone and shall
be entitled to all the benefits of (but shall be subject to all the limitations
of rights set forth in) this Indenture equally and proportionately





                                       22
   29
with any and all other Securities or Coupons of such series duly authenticated
and delivered hereunder.  All Securities and Coupons shall be held and owned
upon the express condition that, to the extent permitted by law, the foregoing
provisions are exclusive with respect to the replacement or payment of
mutilated, defaced or destroyed, lost or stolen Securities and Coupons and
shall preclude any and all other rights or remedies notwithstanding any law or
statute existing or hereafter enacted to the contrary with respect to the
replacement or payment of negotiable instruments or other securities without
their surrender.

                 SECTION 2.10  Cancellation of Securities; Disposition Thereof.
All Securities and Coupons surrendered for payment, redemption, registration of
transfer or exchange, or for credit against any payment in respect of a sinking
or analogous fund, if surrendered to the Issuer or any agent of the Issuer or
the Trustee or any agent of the Trustee, shall be delivered to the Trustee or
its agent for cancellation or, if surrendered to the Trustee, shall be
cancelled by it; and no Securities or Coupons shall be issued in lieu thereof
except as expressly permitted by any of the provisions of this Indenture.  The
Trustee or its agent shall dispose of cancelled Securities and Coupons held by
it and deliver a certificate of disposition to the Issuer.  If the Issuer or
its agent shall acquire any of the Securities or Coupons, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness
represented by such Securities or Coupons unless and until the same are
delivered to the Trustee or its agent for cancellation.

                 SECTION 2.11  Temporary Securities.  Pending the preparation
of definitive Securities for any series, the Issuer may execute and the Trustee
shall authenticate and deliver temporary Securities for such series (printed,
lithographed, typewritten or otherwise reproduced, in each case in form
satisfactory to the Trustee).  Temporary Securities of any series shall be
issuable as Registered Securities without Coupons, or as Unregistered
Securities with or without Coupons attached thereto, of any authorized
denomination, and substantially in the form of the definitive Securities of
such series but with such omissions, insertions and variations as may be
appropriate for temporary Securities, all as may be determined by the Issuer
with the concurrence of the Trustee as evidenced by the execution and
authentication thereof.  Temporary Securities may contain such references to
any provisions of this Indenture as may be appropriate.  Every temporary
Security shall be executed by the Issuer and be authenticated by the Trustee
upon the same conditions and in substantially the same manner, and with like
effect, as the definitive Securities.  Without unreasonable delay the Issuer
shall execute and shall furnish definitive Securities of such series and
thereupon temporary Registered Securities of such series may be





                                       23
   30
surrendered in exchange therefor without charge at each office or agency to be
maintained by the Issuer for that purpose pursuant to Section 3.2 and, in the
case of Unregistered Securities, at any agency maintained by the Issuer for
such purpose as specified pursuant to Section 2.3, and the Trustee shall
authenticate and deliver in exchange for such temporary Securities of such
series an equal aggregate principal amount of definitive Securities of the same
series having authorized denominations and, in the case of Unregistered
Securities, having attached thereto any appropriate Coupons.  Until so
exchanged, the temporary Securities of any series shall be entitled to the same
benefits under this Indenture as definitive Securities of such series, unless
otherwise established pursuant to Section 2.3.  The provisions of this Section
are subject to any restrictions or limitations on the issue and delivery of
temporary Unregistered Securities of any series that may be established
pursuant to Section 2.3 (including any provision that Unregistered Securities
of such series initially be issued in the form of a single global Unregistered
Security to be delivered to a depositary or agency located outside the United
States and the procedures pursuant to which definitive or global Unregistered
Securities of such series would be issued in exchange for such temporary global
Unregistered Security).

   31
                                 ARTICLE THREE

                            COVENANTS OF THE ISSUER




                 SECTION 3.1  Payment of Principal and Interest.  The Issuer
covenants and agrees for the benefit of each series of Securities that it will
duly and punctually pay or cause to be paid the principal of, and interest on,
each of the Securities of such series (together with any additional amounts
payable pursuant to the terms of such Securities) at the place or places, at
the respective times and in the manner provided in such Securities and in the
Coupons, if any, appertaining thereto and in this Indenture.  The interest on
Securities with Coupons attached (together with any additional amounts payable
pursuant to the terms of such Securities) shall be payable only upon
presentation and surrender of the several Coupons for such interest
installments as are evidenced thereby as they severally mature.  If any
temporary Unregistered Security provides that interest thereon may be paid
while such Security is in temporary form, the interest on any such temporary
Unregistered Security (together with any additional amounts payable pursuant to
the terms of such Security) shall be paid, as to the installments of interest
evidenced by Coupons attached thereto, if any, only upon presentation and
surrender thereof, and, as to the other installments of interest, if any, only
upon presentation of such Securities for notation thereon of the payment of
such interest, in each case subject to any restrictions that may be established
pursuant to Section 2.3.  The interest on Registered Securities (together with
any additional amounts payable pursuant to the terms of such Securities) shall
be payable only to or upon the written order of the Holders thereof entitled
thereto and, at the option of the Issuer, may be paid by wire transfer or by
mailing checks for such interest payable to or upon the written order of such
Holders at their last addresses as they appear on the registry books of the
Issuer.

                 SECTION 3.2  Offices for Payments, etc. So long as any
Registered Securities are authorized for issuance pursuant to this Indenture or
are outstanding hereunder, the Issuer will maintain in the Borough of
Manhattan, The City of New York, an office or agency where the Registered
Securities of each series may be presented for payment, where the Securities of
each series may be presented for exchange as is provided in this Indenture and,
if applicable, pursuant to Section 2.3 and where the Registered Securities of
each series may be presented for registration of transfer as in this Indenture
provided.





                                       25
   32
                 The Issuer will maintain one or more offices or agencies in a
city or cities located outside the United States (including any city in which
such an agency is required to be maintained under the rules of any stock
exchange on which the Securities of such series are listed) where the
Unregistered Securities, if any, of each series and Coupons, if any,
appertaining thereto may be presented for payment.  No payment on any
Unregistered Security or Coupon will be made upon presentation of such
Unregistered Security or Coupon at an agency of the Issuer within the United
States nor will any payment be made by transfer to an account in, or by mail to
an address in, the United States unless pursuant to applicable United States
laws and regulations then in effect such payment can be made without adverse
tax consequences to the Issuer.  Notwithstanding the foregoing, payments in
Dollars of Unregistered Securities of any series and Coupons appertaining
thereto which are payable in Dollars may be made at an agency of the Issuer
maintained in the Borough of Manhattan, The City of New York if such payment in
Dollars at each agency maintained by the Issuer outside the United States for
payment on such Unregistered Securities is illegal or effectively precluded by
exchange controls or other similar restrictions.

                 The Issuer will maintain in the Borough of Manhattan, The City
of New York, an office or agency where notices and demands to or upon the
Issuer in respect of the Securities of any series, the Coupons appertaining
thereto or this Indenture may be served.

                 The Issuer will give to the Trustee written notice of the
location of each such office or agency and of any change of location thereof.
In case the Issuer shall fail to maintain any agency required by this Section
to be located in the Borough of Manhattan, The City of New York, or shall fail
to give such notice of the location or of any change in the location of any of
the above agencies, presentations and demands may be made and notices may be
served at the Corporate Trust Office of the Trustee.

                 The Issuer may from time to time designate one or more
additional offices or agencies where the Securities of a series and any Coupons
appertaining thereto may be presented for payment, where the Securities of that
series may be presented for exchange as provided in this Indenture and pursuant
to Section 2.3 and where the Registered Securities of that series may be
presented for registration of transfer as in this Indenture provided, and the
Issuer may from time to time rescind any such designation, as the Issuer may
deem desirable or expedient; provided, however, that no such designation or
rescission shall





                                       26
   33
in any manner relieve the Issuer of its obligation to maintain the agencies
provided for in this Section.  The Issuer will give to the Trustee prompt
written notice of any such designation or rescission thereof.

                 SECTION 3.3  Appointment to Fill a Vacancy in Office of
Trustee.  The Issuer, whenever necessary to avoid or fill a vacancy in the
office of Trustee, will appoint, in the manner provided in Section 5.9, a
Trustee, so that there shall at all times be a Trustee with respect to each
series of Securities hereunder.

                 SECTION 3.4  Paying Agents.  Whenever the Issuer shall appoint
a paying agent other than the Trustee with respect to the Securities of any
series, it will cause such paying agent to execute and deliver to the Trustee
an instrument in which such agent shall agree with the Trustee, subject to the
provisions of this Section,

                 (a)  that it will hold all sums received by it as such agent
         for the payment of the principal of or interest on the Securities of
         such series (whether such sums have been paid to it by the Issuer or
         by any other obligor on the Securities of such series) in trust for
         the benefit of the Holders of the Securities of such series, or
         Coupons appertaining thereto, if any, or of the Trustee,

                 (b)  that it will give the Trustee notice of any failure by
         the Issuer (or by any other obligor on the Securities of such series)
         to make any payment of the principal of or interest on the Securities
         of such series when the same shall be due and payable, and

                 (c)  that it will at any time during the continuance of any
         such failure, upon the written request of the Trustee, forthwith pay
         to the Trustee all sums so held in trust by such paying agent.

                 The Issuer will, on or prior to each due date of the principal
of or interest on the Securities of such series, deposit with the paying agent
a sum sufficient to pay such principal or interest so becoming due, and (unless
such paying agent is the Trustee) the Issuer will promptly notify the Trustee
of any failure to take such action.

                 If the Issuer shall act as its own paying agent with respect
to the Securities of any series, it will, on or before each due date of the
principal of or interest on the Securities of such series, set aside, segregate
and hold in trust for the benefit of the Holders of the Securities of such
series or the





                                       27
   34
Coupons appertaining thereto a sum sufficient to pay such principal or interest
so becoming due.  The Issuer will promptly notify the Trustee of any failure to
take such action.

                 Anything in this Section to the contrary notwithstanding, but
subject to Section 9.1, the Issuer may at any time, for the purpose of
obtaining a satisfaction and discharge with respect to one or more or all
series of Securities hereunder, or for any other reason, pay or cause to be
paid to the Trustee all sums held in trust for any such series by the Issuer or
any paying agent hereunder, as required by this Section, such sums to be held
by the Trustee upon the trusts herein contained.

                 Anything in this Section to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section is subject to the
provisions of Sections 9.3 and 9.4.

                 SECTION 3.5  Written Statement to Trustee.  The Issuer will
furnish to the Trustee on or before May 31 in each year (beginning with May 31,
1996) a brief certificate (which need not comply with Section 10.5) from the
principal executive, financial or accounting officer of the Issuer as to his or
her knowledge of the Issuer's compliance with all conditions and covenants
under the Indenture (such compliance to be determined without regard to any
period of grace or requirement of notice provided under the Indenture).

                 SECTION 3.6  Limitations upon Liens.  After the date hereof
and so long as any Securities are Outstanding, the Issuer will not, and will
not permit any Subsidiary to, issue, assume or guarantee any Indebtedness
secured by a mortgage, pledge, lien, security interest or encumbrance (any
mortgage, pledge, lien, security interest or encumbrance being hereinafter in
this Article referred to as a "mortgage" or "mortgages" or as a "lien" or
"liens") of, or upon any property of the Issuer or of any Subsidiary, without

hereby authorized to enter into an indenture supplemental hereto and to take
such action, if any, as it may deem advisable to enable it to enforce
effectively the rights of the Holders of the Securities so secured, equally and
ratably with such other obligation or Indebtedness.

                                       32
   39
secure the Securities equally and ratably comply with the provisions of this

arrangement with any Person providing for the leasing by the Issuer or a
Subsidiary of any Principal Property, acquired or placed into service more than
180 days prior to such arrangement (except for leases of three years or less),
whereby such property has been or is to be sold or transferred by the Issuer or
any Subsidiary to such Person (herein referred to as a "Sale and Lease-Back
Transaction"), unless:

                 (a)  the Issuer or any Subsidiary would, at the time of
         entering into a Sale and Lease-Back Transaction, be entitled to incur
         Indebtedness secured by a mortgage on the property to be leased in an
         amount at least equal to the Attributable Debt in respect of such
         transaction without equally and ratably securing the Securities
         pursuant to Section 3.6; or

                 (b)  the Issuer shall covenant that it will apply an amount
         equal to the net proceeds from the sale of the Principal Property so
         leased to the retirement (other than any mandatory retirement) of its
         Funded Indebtedness within 90 days of the effective date of any such
         Sale and Lease-Back Transaction, provided that the amount to be
         applied to the retirement of Funded Indebtedness of the Issuer shall
         be reduced by (i) the principal amount of any Securities delivered by
         the Issuer to the Trustee within 90 days after such Sale and
         Lease-Back Transaction for retirement and cancellation, and (ii) the
         principal amount of Funded Indebtedness, other than Securities,
         voluntarily retired by the Issuer within 90 days following such Sale
         and Lease-Back Transaction, provided, further, the covenant contained
         in this Section 3.7 shall not apply to, and there shall be excluded
         from Attributable Debt in any computation under Section 3.6 or this
         Section 3.7, Attributable Debt with respect to any Sale and Lease-Back
         Transaction if:

                 (1)  such Sale and Lease-Back Transaction is entered into in
         connection with transactions which are part of an industrial
         development or pollution control financing or,

                 (2)  the only parties involved in such Sale and Lease-Back
         Transaction are the Issuer and any Subsidiary or any Subsidiaries.

                 For purposes of Section 3.6 and this Section 3.7,





                                       33
   40
"Attributable Debt" means, with respect to any Sale and Lease-Back Transaction
as of any particular time, the present value discounted at the rate of interest
implicit in the terms of the lease of the obligations of the lessee under such
lease for net rental payments during the remaining term of the lease (including
any period for which such lease has been extended or may, at the option of the
Issuer, be extended).

                 For purposes of this Section 3.7, "Principal Property" means

located in the United States, except any such property that in the opinion of
the Board of Directors is not of material importance to the total business
conducted by the Issuer and its consolidated Subsidiaries.  "Principal
Property" shall not include (i) any oil and natural gas property or the
production or proceeds from production from an oil or natural gas producing
property or the production or proceeds from production of gas processing plants
or oil or natural gas or petroleum products in any pipeline or storage field
and (ii) any property acquired or constructed by any Subsidiary of the Issuer
after June 30, 1992.

publication of any notice pursuant to Section 4.11, 5.9(a), 5.10, 7.2, 9.4,
11.2 or 11.5, the party making such publication in the Borough of Manhattan,
The City of New York and London shall also, to the extent that notice is
required to be given to Holders of Securities of any series by applicable
Luxembourg law or stock exchange regulation, as evidenced by an Officers'
Certificate delivered to such party, make a similar publication in Luxembourg.

                 SECTION 3.9  Securityholders Lists.  If and so long as the
Trustee shall not be the Security registrar for the Securities of any series,
the Issuer will furnish or cause to be furnished to the Trustee a list in such
form as the Trustee may reasonably require of the names and addresses of the

as the Trustee may request in writing, within thirty days after receipt by the

Maturity; Waiver of Default.  "Event of Default" with respect to Securities of
any series wherever used herein, means each one of the following events which

                 (a)  default in the payment of any instalment of interest upon

                 (c)  default in the performance, or breach, of any covenant or
         warranty of the Issuer in the Securities of such series (other than a
         covenant or warranty in respect of the Securities of such series a
         default in whose performance or whose breach is elsewhere in this
         Section specifically dealt with) and continuance of such default or
         breach for a period of 90 days after there has been given, by

                                       35
   42
         Issuer and the Trustee by the Holders of at least 25% in aggregate
         principal amount of the Outstanding Securities of all series affected
         thereby, a written notice specifying such default or breach and

         of Default" hereunder; or

                 (d)  the entry of a decree or order by a court having
         jurisdiction in the premises adjudging the Issuer a bankrupt or
         insolvent, or approving as properly filed a petition seeking
         reorganization arrangement, adjustment or composition of or in respect
         of the Issuer under the Federal bankruptcy law or any other applicable
         Federal or state law, or appointing a receiver, liquidator, assignee,
         trustee, sequestrator (or other similar official) of the Issuer or of
         any substantial part of its property, or ordering the winding up or

         adjudicated a bankrupt or insolvent or the consent by it to the
         institution of bankruptcy or insolvency proceedings against it, or the
         filing by it of a petition or answer or consent seeking reorganization
         or relief under the Federal bankruptcy law or any other applicable
         Federal or state law, or the consent by it to the filing of any such

         assignment for the benefit of creditors;

                 (f)  any other Event of Default provided in the supplemental
         indenture under which such series of Securities is issued or in the
         form of Security for such series;

provided, however, that the occurrence of any of the events described in the
foregoing clause (c) or (f) shall not constitute an Event of Default if such
occurrence is the result of changes in generally accepted accounting principles
as recognized by the American Institute of Certified Public Accountants at the
date as of which this Indenture is executed and a certificate to such effect is
delivered to the Trustee by the Issuer's independent public accountants.

                 If an Event of Default described in clauses (a), (b), (c) or
(f) (if the Event of Default under clause (c) or (f), as the case may be, is
with respect to less than all series of Securities then Outstanding) occurs and
is continuing, then, and





                                       36
   43
in each and every such case, except for any series of Securities the principal
of which shall have already become due and payable, either the Trustee or the
Holders of not less than 25% in aggregate principal amount of the Securities of
each such affected series then Outstanding hereunder (voting as a single class)
by notice in writing to the Issuer (and to the Trustee if given by
Securityholders), may declare the entire principal (or, if the Securities of
any such affected series are Original Issue Discount Securities, such portion
of the principal amount as may be specified in the terms of such series) of all
Securities of all such affected series, and the interest accrued thereon, if
any, to be due and payable immediately, and upon any such declaration, the same
shall become immediately due and payable.  If an Event of Default described in
clause (c) or (f) (if the Event of Default under clause (c) or (f), as the case
may be, is with respect to all series of Securities then Outstanding), (d) or
(e) occurs and is continuing, then and in each and every such case, unless the
principal of all the Securities shall have already become due and payable,
either the Trustee or the Holders of not less than 25% in aggregate principal
amount of all the Securities then Outstanding hereunder (treated as one class),
by notice in writing to the Issuer (and to the Trustee if given by
Securityholders), may declare the entire principal (or, if any Securities are
Original Issue Discount Securities, such portion of the principal as may be
specified in the terms thereof) of all the Securities then Outstanding, and
interest accrued thereon, if any, to be due and payable immediately, and upon
any such declaration the same shall become immediately due and payable.

                 The foregoing provisions, however, are subject to the
condition that if, at any time after the principal (or, if the Securities are
Original Issue Discount Securities, such portion of the principal as may be
specified in the terms thereof) of the Securities of any series (or of all the
Securities, as the case may be) shall have been so declared due and payable,
and before any judgment or decree for the payment of the moneys due shall have
been obtained or entered as hereinafter provided, the Issuer shall pay or shall
deposit with the Trustee a sum sufficient to pay all matured installments of
interest upon all the Securities of such series (or of all the Securities, as
the case may be) and the principal of any and all Securities of each such
series (or of all the Securities, as the case may be) which shall have become
due otherwise than by acceleration (with interest upon such principal and, to
the extent that payment of such interest is enforceable under applicable law,
on overdue installments of interest, at the same rate as the rate of interest
or Yield to Maturity (in the case of Original Issue Discount Securities)
specified in the Securities of each such series (or at the respective rates of
interest or Yields to Maturity of all the Securities, as the case may be) to
the date of such payment or





                                       37

deposit) and such amount as shall be sufficient to cover reasonable
compensation to the Trustee and each predecessor Trustee, its agents, attorneys
and counsel, and all other expenses and liabilities incurred, and all advances
made, by the Trustee and each predecessor Trustee except as a result of
negligence or bad faith, and if any and all Events of Default under the
Indenture, other than the non-payment of the principal of Securities which
shall have become due by acceleration, shall have been cured, waived or
otherwise remedied as provided herein--then and in every such case the Holders
of a majority in aggregate principal amount of all the Securities of each such
series, or of all the Securities, in each case voting as a single class, then
Outstanding, by written notice to the Issuer and to the Trustee, may waive all
defaults with respect to each such series (or with respect to all the
Securities, as the case may be) and rescind and annul such declaration and its
consequences, but no such waiver or rescission and annulment shall extend to or
shall affect any subsequent default or shall impair any right consequent
thereon.

For all purposes under this Indenture, if a portion of the principal of any
Original Issue Discount Securities shall have been accelerated and declared due
and payable pursuant to the provisions hereof, then, from and after such
declaration, unless such declaration has been rescinded and annulled, the
principal amount of such Original Issue Discount Securities shall be deemed,
for all purposes hereunder, to be such portion of the principal thereof as
shall be due and payable as a result of such acceleration, and payment of such
portion of the principal thereof as shall be due and payable as a result of
such acceleration, together with interest, if any, thereon and all other
amounts owing thereunder, shall constitute payment in full of such Original
Issue Discount Securities.

                 SECTION 4.2  Collection of Indebtedness by Trustee; Trustee
May Prove Debt.  The Issuer covenants that (a) in case default shall be made in
the payment of any instalment of interest on any of the Securities of any
series when such interest shall have become due and payable, and such default
shall have continued for a period of 30 days or (b) in case default shall be
made in the payment of all or any part of the principal of any of the
Securities of any series when the same shall have become due and payable,
whether upon maturity of the Securities of such series or upon any redemption
or by declaration or otherwise -- then upon demand of the Trustee, the Issuer
will pay to the Trustee for the benefit of the Holders of the Securities of
such series the whole amount that then shall have become due and payable on all
Securities of such series, and such Coupons, for principal or interest, as the
case may be (with interest to the date of such payment upon the overdue
principal





                                       38
   45
and, to the extent that payment of such interest is enforceable under
applicable law, on overdue installments of interest at the same rate as the
rate of interest or Yield to Maturity (in the case of Original Issue Discount
Securities) specified in the Securities of such series); and in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including reasonable compensation to the Trustee and
each predecessor Trustee, their respective agents, attorneys and counsel, and
any expenses and liabilities incurred, and all advances made, by the Trustee
and each predecessor Trustee except as a result of its negligence or bad faith.

                 Until such demand is made by the Trustee, the Issuer may pay
the principal of and interest on the Securities of any series to the registered
Holders, whether or not the Securities of such series be overdue.

                 In case the Issuer shall fail forthwith to pay such amounts
upon such demand, the Trustee, in its own name and as trustee of an express
trust, shall be entitled and empowered to institute any action or proceedings
at law or in equity for the collection of the sums so due and unpaid, and may
prosecute any such action or proceedings to judgment or final decree, and may
enforce any such judgment or final decree against the Issuer or other obligor
upon the Securities and collect in the manner provided by law out of the
property of the Issuer or other obligor upon the Securities, wherever situated
the moneys adjudged or decreed to be payable.

                 In case there shall be pending proceedings relative to the
Issuer or any other obligor upon the Securities under Title 11 of the United
States Code or any other applicable Federal or state bankruptcy, insolvency or
other similar law, or in case a receiver, assignee or trustee in bankruptcy or
reorganization, liquidator, sequestrator or similar official shall have been
appointed for or taken possession of the Issuer or its property or such other
obligor, or in case of any other comparable judicial proceedings relative to
the Issuer or other obligor upon the Securities, or to the creditors or
property of the Issuer or such other obligor, the Trustee, irrespective of
whether the principal of the Securities shall then be due and payable as
therein expressed or by declaration or otherwise and irrespective of whether
the Trustee shall have made any demand pursuant to the provisions of this
Section, shall be entitled and empowered, by intervention in such proceedings
or otherwise:

                 (a)  to file and prove a claim or claims for the whole amount
         of principal and interest  (or, if the Securities of any series are
         Original Issue Discount Securities, such portion of the principal
         amount as may be specified in the





                                       39
   46
         terms of such series) owing and unpaid in respect of the Securities of
         any series, and to file such other papers or documents as may be
         necessary or advisable in order to have the claims of the Trustee
         (including any claim for reasonable compensation to the Trustee and
         each predecessor Trustee, and their respective agents, attorneys and
         counsel, and for reimbursement of all expenses and liabilities
         incurred, and all advances made, by the Trustee and each predecessor
         Trustee, except as a result of negligence or bad faith) and of the
         Securityholders allowed in any judicial proceedings relative to the
         Issuer or other obligor upon the Securities, or to the creditors or
         property of the Issuer or such other obligor,

                 (b)  unless prohibited by applicable law and regulations, to
         vote on behalf of the Holders of the Securities of any series in any
         election of a trustee or a standby trustee in arrangement,
         reorganization, liquidation or other bankruptcy or insolvency
         proceedings or Person performing similar functions in comparable
         proceedings, and

                 (c)  to collect and receive any moneys or other property
         payable or deliverable on any such claims, and to distribute all
         amounts received with respect to the claims of the Securityholders and
         of the Trustee on their behalf; and any trustee, receiver, or
         liquidator, custodian or other similar official is hereby authorized
         by each of the Securityholders to make payments to the Trustee, and,
         in the event that the Trustee shall consent to the making of payments
         directly to the Securityholders, to pay to the Trustee such amounts as
         shall be sufficient to cover reasonable compensation to the Trustee,
         each predecessor Trustee and their respective agents, attorneys and
         counsel, and all other expenses and liabilities incurred, and all
         advances made, by the Trustee and each predecessor Trustee except as a
         result of negligence or bad faith.

                 Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or vote for or accept or adopt on behalf of
any Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities of any series or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any
Securityholder in any such proceeding except, as aforesaid, to vote for the
election of a trustee in bankruptcy or similar Person.


                 All rights of action and of asserting claims under this
Indenture, or under any of the Securities of any series or





                                       40
   47
Coupons appertaining to such Securities, may be enforced by the Trustee without
the possession of any of the Securities of such series or Coupons appertaining
to such Securities or the production thereof on any trial or other proceedings
relative thereto, and any such action or proceedings instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment, subject to the payment of the expenses, disbursements and
compensation of the Trustee, each predecessor Trustee and their respective
agents and attorneys, shall be for the ratable benefit of the Holders of the
Securities or Coupons appertaining to such Securities in respect of which such
action was taken.

                 In any proceedings brought by the Trustee (and also any
proceedings involving the interpretation of any provision of this Indenture to
which the Trustee shall be a party) the Trustee shall be held to represent all
the Holders of the Securities or Coupons appertaining to such Securities in
respect to which such action was taken, and it shall not be necessary to make
any Holders of such Securities or Coupons appertaining to such Securities
parties to any such proceedings.

                 SECTION 4.3  Application of Proceeds.  Any moneys collected by
the Trustee pursuant to this Article in respect of any series shall be applied
in the following order at the date or dates fixed by the Trustee and, in case
of the distribution of such moneys on account of principal or interest, upon
presentation of the several Securities and Coupons appertaining to such
Securities in respect of which monies have been collected and stamping (or
otherwise noting) thereon the payment, or issuing Securities of such series in
reduced principal amounts in exchange for the presented Securities of like
series if only partially paid, or upon surrender thereof if fully paid:

                 FIRST:  To the payment of costs and expenses applicable to
such series in respect of which monies have been collected, including
reasonable compensation to the Trustee and each predecessor Trustee and their
respective agents and attorneys and of all expenses and liabilities incurred,
and all advances made, by the Trustee and each predecessor Trustee except as a
result of negligence or bad faith;

                 SECOND:  In case the principal of the Securities of such
series in respect of which moneys have been collected shall not have become and
be then due and payable, to the payment of interest on the Securities of such
series in default in the order of the maturity of the installments of such
interest, with interest (to the extent that such interest has been collected by
the Trustee) upon the overdue installments of interest at the same rate as the
rate of interest or Yield to Maturity (in the





                                       41
   48
case of Original Issue Discount Securities) specified in such Securities, such
payments to be made ratably to the Persons entitled thereto, without
discrimination or preference;

                 THIRD:  In case the principal of the Securities of such series
in respect of which moneys have been collected shall have become and shall be
then due and payable, to the payment of the whole amount then owing and unpaid
upon all the Securities of such series for principal and interest, with
interest upon the overdue principal, and (to the extent that such interest has
been collected by the Trustee) upon overdue installments of interest at the
same rate as the rate of interest or Yield to Maturity (in the case of Original
Issue Discount Securities) specified in the Securities of such series; and in
case such moneys shall be insufficient to pay in full the whole amount so due
and unpaid upon the Securities of such series, then to the payment of such
principal and interest or Yield to Maturity, without preference or priority of
principal over interest or Yield to Maturity, or of interest or Yield to
Maturity over principal, or of any instalment of interest over any other
instalment of interest, or of any Security of such series over any other
Security of such series, ratably to the aggregate of such principal and accrued
and unpaid interest or Yield to Maturity; and

                 FOURTH:  To the payment of the remainder, if any, to the
Issuer or any other Person lawfully entitled thereto.

                 SECTION 4.4  Suits for Enforcement.  In case an Event of
Default has occurred, has not been waived and is continuing, the Trustee may in
its discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

                 SECTION 4.5  Restoration of Rights on Abandonment of
Proceedings.  In case the Trustee shall have proceeded to enforce any right
under this Indenture and such proceedings shall have been discontinued or
abandoned for any reason, or shall have been determined adversely to the
Trustee, then and in every such case the Issuer and the Trustee shall be
restored respectively to their former positions and rights hereunder, and all
rights, remedies and powers of the Issuer, the Trustee and the Securityholders
shall continue as though no such proceedings had been taken.

   49
                 SECTION 4.6  Limitations on Suits by Securityholders.  No
Holder of any Security of any series or of any Coupon appertaining thereto
shall have any right by virtue or by availing of any provision of this
Indenture to institute any action or proceeding at law or in equity or in
bankruptcy or otherwise upon or under or with respect to this Indenture, or for
the appointment of a trustee, receiver, liquidator, custodian or other similar
official or for any other remedy hereunder, unless such Holder previously shall
have given to the Trustee written notice of default and of the continuance
thereof, as hereinbefore provided, and unless also the Holders of not less than
25% in aggregate principal amount of the Securities of each affected series
then Outstanding (treated as a single class) shall have made written request
upon the Trustee to institute such action or proceedings in its own name as
Trustee hereunder and shall have offered to the Trustee such reasonable
indemnity as it may require against the costs, expenses and liabilities to be
incurred therein or thereby and the Trustee for 60 days after its receipt of
such notice, request and offer of indemnity shall have failed to institute any
such action or proceeding and no direction inconsistent with such written
request shall have been given to the Trustee pursuant to Section 4.9; it being
understood and intended, and being expressly covenanted by the taker and Holder
of every Security or Coupon with every other taker and Holder and the Trustee,
that no one or more Holders of Securities of any series or Coupons appertaining
to such Securities shall have any right in any manner whatever by virtue or by
availing of any provision of this Indenture to affect, disturb or prejudice the
rights of any other such Holder of Securities or Coupons appertaining to such
Securities, or to obtain or seek to obtain priority over or preference to any
other such Holder or to enforce any right under this Indenture, except in the
manner herein provided and for the equal, ratable and common benefit of all
Holders of Securities of the applicable series and Coupons appertaining to such
Securities.  For the protection and enforcement of the provisions of this
Section, each and every Securityholder and the Trustee shall be entitled to
such relief as can be given either at law or in equity.

                 SECTION 4.7  Unconditional Right of Securityholders to
Institute Certain Suits.  Notwithstanding any other provision in this Indenture
and any provision of any Security, the right of any Holder of any Security or
Coupon to receive payment of the principal of and interest on such Security or
Coupon on or after the respective due dates expressed or provided for in such
Security or Coupon, or to institute suit for the enforcement of any such
payment on or after such respective dates, shall not be impaired or affected
without the consent of such Holder.

                 SECTION 4.8  Powers and Remedies Cumulative; Delay or





                                       43
   50
Omission Not Waiver of Default.  Except as provided in Section 4.6 and the last
paragraph of Section 2.9, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders of Securities or Coupons is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to
the extent permitted by law, be cumulative and in addition to every other right
and remedy given hereunder or now or hereafter existing at law or in equity or
otherwise.  The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any
other appropriate right or remedy.

                 No delay or omission of the Trustee or of any Holder of
Securities or Coupons to exercise any right or power accruing upon any Event of
Default occurring and continuing as aforesaid shall impair any such right or
power or shall be construed to be a waiver of any such Event of Default or an
acquiescence therein; and, subject to Section 4.6, every power and remedy given
by this Indenture or by law to the Trustee or to the Holders of Securities or
Coupons may be exercised from time to time, and as often as shall be deemed
expedient, by the Trustee or by the Holders of Securities or Coupons.

                 SECTION 4.9  Control by Holders of Securities.  The Holders of
a majority in aggregate principal amount of the Securities of each series
affected (with all such series voting as a single class) at the time
Outstanding shall have the right to direct the time, method, and place of
conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee with respect to the
Securities of such series by this Indenture; provided that such direction shall
not be otherwise than in accordance with law and the provisions of this
Indenture and provided further that (subject to the provisions of Section 5.1)
the Trustee shall have the right to decline to follow any such direction if the
Trustee, being advised by counsel, shall determine that the action or
proceeding so directed may not lawfully be taken or if the Trustee in good
faith by its board of directors, the executive committee, or a trust committee
of directors or Responsible Officers of the Trustee shall determine that the
action or proceedings so directed would involve the Trustee in personal
liability or if the Trustee in good faith shall so determine that the actions
or forebearances specified in or pursuant to such direction would be unduly
prejudicial to the interests of Holders of the Securities of all series so
affected not joining in the giving of said direction, it being understood that
(subject to Section 5.1) the Trustee shall have no duty to ascertain whether or
not such actions or forebearances are unduly prejudicial to such Holders.





                                       44
   51
                 Nothing in this Indenture shall impair the right of the
Trustee in its discretion to take any action deemed proper by the Trustee and
which is not inconsistent with such direction or directions by Securityholders.

                 SECTION 4.10  Waiver of Past Defaults.  Prior to the
acceleration of the maturity of any Securities as provided in Section 4.1, the
Holders of a majority in aggregate principal amount of the Securities of all
series at the time Outstanding with respect to which an Event of Default shall
have occurred and be continuing (voting as a single class) may on behalf of the
Holders of all such Securities waive any past default or Event of Default
described in Section 4.1 and its consequences, except a default in respect of a
covenant or provision hereof which cannot be modified or amended without the
consent of the Holder of each Security affected.  In the case of any such
waiver, the Issuer, the Trustee and the Holders of all such Securities shall be
restored to their former positions and rights hereunder, respectively; but no
such waiver shall extend to any subsequent or other default or impair any right
consequent thereon.


                 Upon any such waiver, such default shall cease to exist and be
deemed to have been cured and not to have occurred, and any Event of Default
arising therefrom shall be deemed to have been cured, and not to have occurred
for every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other default or Event of Default or impair any right consequent
thereon.

                 SECTION 4.11  Trustee to Give Notice of Default, But May
Withhold in Certain Circumstances.  The Trustee shall, within 90 days after the
occurrence of a default with respect to the Securities of any series, give
notice of all defaults with respect to that series known to the Trustee (i) if
any Unregistered Securities of that series are then Outstanding, to the Holders
thereof, by publication at least once in an Authorized Newspaper in the Borough
of Manhattan, The City of New York and at least once in an Authorized Newspaper
in London (and, if required by Section 3.8, at least once in an Authorized
Newspaper in Luxembourg) and (ii) to all Holders of Securities of such series
in the manner and to the extent provided in Section 313(c) of the Trust
Indenture Act of 1939, unless in each case such defaults shall have been cured
before the mailing or publication of such notice (the term "defaults" for the
purpose of this Section being hereby defined to mean any event or condition
which is, or with notice or lapse of time or both would become, an Event of
Default); provided that, except in the case of default in the payment of the
principal of or interest on any of the Securities of such series, or in the
payment of any sinking fund instalment on such series, the Trustee shall be





                                       45
   52
protected in withholding such notice if and so long as the board of directors,
the executive committee, or a trust committee of directors or trustees and/or
Responsible Officers of the Trustee in good faith determines that the
withholding of such notice is in the interests of the Securityholders of such
series.

                 SECTION 4.12  Right of Court to Require Filing of Undertaking
to Pay Costs.  All parties to this Indenture agree, and each Holder of any
Security or Coupon by his acceptance thereof shall be deemed to have agreed,
that any court may in its discretion require, in any suit for the enforcement
of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken, suffered or omitted by it as Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit,
and that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in such suit, having due
regard to the merits and good faith of the claims or defenses made by such
party litigant; but the provisions of this Section shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Securityholder or
group of Securityholders of any series holding in the aggregate more than 10%
in aggregate principal amount of the Securities of such series, or, in the case
of any suit relating to or arising under clause (c) or (f) of Section 4.1 (if
the suit relates to Securities of more than one but less than all series), l0%
in aggregate principal amount of Securities then Outstanding and affected
thereby, or in the case of any suit relating to or arising under clause (c) or
(f) (if the suit under clause (c) or (f) relates to all the Securities then
Outstanding), (d) or (e) of Section 4.1, 10% in aggregate principal amount of
all Securities then Outstanding, or to any suit instituted by any
Securityholder for the enforcement of the payment of the principal of or
interest on any Security on or after the due date expressed in such Security or
any date fixed for redemption.


                                  ARTICLE FIVE


                             CONCERNING THE TRUSTEE

                 SECTION 5.1  Duties and Responsibilities of the Trustee;
During Default; Prior to Default.  With respect to the Holders of any series of
Securities issued hereunder, the Trustee, prior to the occurrence of an Event
of Default with respect to the Securities of a particular series and after the
curing or waiving of all Events of Default which may have occurred with respect
to such series, undertakes to perform such duties and only such duties as are
specifically set forth in this





                                       46
   53
Indenture.  In case an Event of Default with respect to the Securities of a
series has occurred (which has not been cured or waived) the Trustee shall
exercise with respect to such series of Securities such of the rights and
powers vested in it by this Indenture, and use the same degree of care and
skill in their exercise, as a prudent man would exercise or use under the
circumstances in the conduct of his own affairs.

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

                 (a)  prior to the occurrence of an Event of Default with
         respect to the Securities of any series and after the curing or
         waiving of all such Events of Default with respect to such series
         which may have occurred:

                 (i)  the duties and obligations of the Trustee with respect to
         the Securities of any series shall be determined solely by the express
         provisions of this Indenture, and the Trustee shall not be liable
         except for the performance of such duties and obligations as are
         specifically set forth in this Indenture, and no implied covenants or
         obligations shall be read into this Indenture against the Trustee; and

                 (ii)  in the absence of bad faith on the part of the Trustee,
         the Trustee may conclusively rely, as to the truth of the statements
         and the correctness of the opinions expressed therein, upon any
         statements, certificates or opinions furnished to the Trustee and
         conforming to the requirements of this Indenture; but in the case of
         any such statements, certificates or opinions which by any provision
         hereof are specifically required to be furnished to the Trustee, the
         Trustee shall be under a duty to examine the same to determine whether
         or not they conform to the requirements of this Indenture;

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

                 (c)  the Trustee shall not be liable with respect to any
         action taken or omitted to be taken by it in good faith in accordance
         with the direction of the Holders pursuant to Section 4.9 relating to
         the time, method and place of conducting any proceeding for any remedy
         available to the Trustee, or exercising any trust or power conferred
         upon the





                                       47
   54
         Trustee, under this Indenture.

                 None of the provisions contained in this Indenture shall
require the Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise
of any of its rights or powers, if there shall be reasonable ground for
believing that the repayment of such funds or adequate indemnity against such
liability is not reasonably assured to it.

                 The provisions of this Section 5.1 are in furtherance of and
subject to Sections 315 and 316 of the Trust Indenture Act of 1939.

                 SECTION 5.2  Certain Rights of the Trustee.  In furtherance of
and subject to the Trust Indenture Act of 1939, subject to Section 5.1:

                 (a)  the Trustee may rely and shall be protected in acting or
         refraining from acting upon any resolution, Officers' Certificate or
         any other certificate, statement, instrument, opinion, report, notice,
         request, consent, order, bond, debenture, note, Coupon, Security or
         other paper or document believed by it to be genuine and to have been
         signed or presented by the proper party or parties;

                 (b)  any request, direction, order or demand of the Issuer
         mentioned herein shall be sufficiently evidenced by an Officers'
         Certificate (unless other evidence in respect thereof be herein
         specifically prescribed); and any resolution of the Board of Directors
         may be evidenced to the Trustee by a copy thereof certified by the
         secretary or an assistant secretary of the Issuer;

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

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





                                       48
   55
                 (e)  the Trustee shall not be liable for any action taken or
         omitted by it in good faith and believed by it to be authorized or
         within the discretion, rights or powers conferred upon it by this
         Indenture;

                 (f)  prior to the occurrence of an Event of Default hereunder
         and after the curing or waiving of all Events of Default, the Trustee
         shall not be bound to make any investigation into the facts or matters
         stated in any resolution, certificate, statement, instrument, opinion,
         report, notice, request, consent, order, approval, appraisal, bond,
         debenture, note, Coupon, Security, or other paper or document unless
         requested in writing so to do by the Holders of not less than a
         majority in aggregate principal amount of the Securities of all series
         affected then Outstanding; provided that, if the payment within a
         reasonable time to the Trustee of the costs, expenses or liabilities
         likely to be incurred by it in the making of such investigation is, in
         the opinion of the Trustee, not reasonably assured to the Trustee by
         the security afforded to it by the terms of this Indenture, the
         Trustee may require reasonable indemnity against such expenses or
         liabilities as a condition to proceeding; the reasonable expenses of
         every such investigation shall be paid by the Issuer or, if paid by
         the Trustee or any predecessor Trustee, shall be repaid by the Issuer
         upon demand; and

                 (g)  the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents or attorneys not regularly in its employ and the
         Trustee shall not be responsible for any misconduct or negligence on
         the part of any such agent or attorney appointed with due care by it
         hereunder.

                 SECTION 5.3  Trustee Not Responsible for Recitals, Disposition
of Securities or Application of Proceeds Thereof.  The recitals contained
herein and in the Securities, except the Trustee's certificates of
authentication, shall be taken as the statements of the Issuer, and the Trustee
assumes no responsibility for the correctness of the same.  The Trustee makes
no representation as to the validity or sufficiency of this Indenture or of the
Securities or Coupons.  The Trustee shall not be accountable for the use or
application by the Issuer of any of the Securities or of the proceeds thereof.

                 SECTION 5.4  Trustee and Agents May Hold Securities or
Coupons; Collections, etc.  The Trustee or any agent of the Issuer or the
Trustee, in its individual or any other capacity, may become the owner or
pledgee of Securities or Coupons with the same rights it would have if it were
not the Trustee or such





                                       49
   56
agent and may otherwise deal with the Issuer and receive, collect, hold and
retain collections from the Issuer with the same rights it would have if it
were not the Trustee or such agent.

                 SECTION 5.5  Moneys Held by Trustee.  Subject to the
provisions of Section 9.4 hereof, all moneys received by the Trustee shall,
until used or applied as herein provided, be held in trust for the purposes for
which they were received, but need not be segregated from other funds except to
the extent required by mandatory provisions of law.  Neither the Trustee nor
any agent of the Issuer or the Trustee shall be under any liability for
interest on any moneys received by it hereunder.

                 SECTION 5.6  Compensation and Indemnification of Trustee and
Its Prior Claim.  The Issuer covenants and agrees to pay to the Trustee from
time to time, and the Trustee shall be entitled to, reasonable compensation
(which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust) and the Issuer covenants and
agrees to pay or reimburse the Trustee and each predecessor Trustee upon its
request for all reasonable expenses, disbursements and advances incurred or
made by or on behalf of it in accordance with any of the provisions of this
Indenture (including the reasonable compensation and the expenses and
disbursements of its counsel and of all agents and other persons not regularly
in its employ) except any such expense, disbursement or advance as may arise
from its negligence or bad faith.  The Issuer also covenants to indemnify the
Trustee and each predecessor Trustee for, and to hold it harmless against, any
loss, liability or expense incurred without negligence or bad faith on its
part, arising out of or in connection with the acceptance or administration of
this Indenture or the trusts hereunder and its duties hereunder, including the
costs and expenses of defending itself against or investigating any claim of
liability in the premises.  The obligations of the Issuer under this Section to
compensate and indemnify the Trustee and each predecessor Trustee and to pay or
reimburse the Trustee and each predecessor Trustee for expenses, disbursements
and advances shall constitute additional indebtedness hereunder and shall
survive the satisfaction and discharge of this Indenture.  Such additional
indebtedness shall be a senior claim to that of the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the benefit of the Holders of particular Securities or Coupons,
and the Securities are hereby subordinated to such senior claim.

                 SECTION 5.7  Right of Trustee to Rely on Officers'
Certificate, etc. Subject to Sections 5.1 and 5.2, whenever in the
administration of the trusts of this Indenture the Trustee





                                       50
   57
shall deem it necessary or desirable that a matter be proved or established
prior to taking or suffering or omitting any action hereunder, such matter
(unless other evidence in respect thereof be herein specifically prescribed)
may, in the absence of negligence or bad faith on the part of the Trustee, be
deemed to be conclusively proved and established by an Officers' Certificate
delivered to the Trustee, and such certificate, in the absence of negligence or
bad faith on the part of the Trustee, shall be full warrant to the Trustee for
any action taken, suffered or omitted by it under the provisions of this
Indenture upon the faith thereof.

                 SECTION 5.8  Persons Eligible for Appointment as Trustee.  The
Trustee for each series of Securities hereunder shall at all times be a
corporation organized and doing business under the laws of the United States of
America or of any State or the District of Columbia having a combined capital
and surplus of at least $5,000,000, and which is eligible in accordance with
the provisions of Section 310(a) of the Trust Indenture Act of 1939.  If such
corporation publishes reports of condition at least annually, pursuant to law
or to the requirements of a Federal, State or District of Columbia supervising
or examining authority, then for the purposes of this Section, the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published.

                 SECTION 5.9  Resignation and Removal; Appointment of Successor
Trustee.  (a)  The Trustee, or any trustee or trustees hereafter appointed, may
at any time resign with respect to one or more or all series of Securities by
giving written notice of resignation to the Issuer and (i) if any Unregistered
Securities of a series affected are then Outstanding, by giving notice of such
resignation to the Holders thereof, by publication at least once in an
Authorized Newspaper in the Borough of Manhattan, The City of New York, and at
least once in an Authorized Newspaper in London (and, if required by Section
3.8, at least once in an Authorized Newspaper in Luxembourg), (ii) if any
Unregistered Securities of a series affected are then Outstanding, by mailing
notice of such resignation to the Holders thereof who have filed their names
and addresses with the Trustee pursuant to Section 313(c)(2) of the Trust
Indenture Act of 1939 at such addresses as were so furnished to the Trustee and
(iii) by mailing notice of such resignation to the Holders of then Outstanding
Registered Securities of each series affected at their addresses as they shall
appear on the registry books.  Upon receiving such notice of resignation, the
Issuer shall promptly appoint a successor trustee or trustees with respect to
the applicable series by written instrument in duplicate, executed by authority
of the Board of Directors, one copy of which instrument shall be





                                       51
   58
delivered to the resigning Trustee and one copy to the successor trustee or
trustees.  If no successor trustee shall have been so appointed with respect to
any series and have accepted appointment within 30 days after the mailing of
such notice of resignation, the resigning trustee may petition any court of
competent jurisdiction for the appointment of a successor trustee, or any
Securityholder who has been a bona fide Holder of a Security or Securities of
the applicable series for at least six months may, subject to the provisions of
Section 4.12, on behalf of himself and all others similarly situated, petition
any such court for the appointment of a successor trustee.  Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe,
appoint a successor trustee.

                 (b)  In case at any time any of the following shall occur:


                 (i)  the Trustee shall fail to comply with the provisions of
         Section 310(b) of the Trust Indenture Act of 1939 with respect to any
         series of Securities after written request therefor by the Issuer or
         by any Securityholder who has been a bona fide Holder of a Security or
         Securities of such series for at least six months; or

                 (ii)  the Trustee shall cease to be eligible in accordance
         with the provisions of Section 310(a) of the Trust Indenture Act of
         1939 and shall fail to resign after written request therefor by the
         Issuer or by any Securityholder; or

                 (iii)  the Trustee shall become incapable of acting with
         respect to any series of Securities, or shall be adjudged a bankrupt
         or insolvent, or a receiver or liquidator of the Trustee or of its
         property shall be appointed, or any public officer shall take charge
         or control of the Trustee or of its property or affairs for the
         purpose of rehabilitation, conservation or liquidation;then, in any
         such case, the Issuer may remove the Trustee with respect to the
         applicable series of Securities and appoint a successor trustee for
         such series by written instrument, in duplicate, executed by order of
         the Board of Directors, one copy of which instrument shall be
         delivered to the Trustee so removed and one copy to the successor
         trustee, or, subject to Section 315(e) of the Trust Indenture Act of
         1939, any Securityholder who has been a bona fide Holder of a Security
         or Securities of such series for at least six months may on behalf of
         himself and all others similarly situated, petition any court of
         competent jurisdiction for the removal of the Trustee and the
         appointment of a





                                       52
   59
         successor trustee with respect to such series.  Such court may
         thereupon, after such notice, if any, as it may deem proper and
         prescribe, remove the Trustee and appoint a successor trustee.

                 (c)  The Holders of a majority in aggregate principal amount
         of the Securities of each series at the time Outstanding may at any
         time remove the Trustee with respect to Securities of such series and
         appoint a successor trustee with respect to the Securities of such
         series by delivering to the Trustee so removed, to the successor
         trustee so appointed and to the Issuer the evidence provided for in
         Section 6.1 of the action in that regard taken by the Securityholders.

                 (d)  Any resignation or removal of the Trustee with respect to
         any series and any appointment of a successor trustee with respect to
         such series pursuant to any of the provisions of this Section 5.9
         shall become effective upon acceptance of appointment by the successor
         trustee as provided in Section 5.10.

                 SECTION 5.10  Acceptance of Appointment by Successor Trustee.
Any successor trustee appointed as provided in Section 5.9 shall execute and
deliver to the Issuer and to its predecessor trustee an instrument accepting
such appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee with respect to all or any applicable series shall become
effective and such successor trustee, without any further act, deed or
conveyance, shall become vested with all rights, powers, duties and obligations
with respect to such series of its predecessor hereunder, with like effect as
if originally named as trustee for such series hereunder; but, nevertheless, on
the written request of the Issuer or of the successor trustee, upon payment of
its charges then unpaid, the trustee ceasing to act shall, subject to Section
9.4, pay over to the successor trustee all moneys at the time held by it
hereunder and shall execute and deliver an instrument transferring to such
successor trustee all such rights, powers, duties and obligations.  Upon
request of any such successor trustee, the Issuer shall execute any and all
instruments in writing for more fully and certainly vesting in and confirming
to such successor trustee all such rights and powers.  Any trustee ceasing to
act shall, nevertheless, retain a prior claim upon all property or funds held
or collected by such trustee to secure any amounts then due it pursuant to the
provisions of Section 5.6.

                 If a successor trustee is appointed with respect to the
Securities of one or more (but not all) series, the Issuer, the predecessor
trustee and each successor trustee with respect to





                                       53
   60
the Securities of any applicable series shall execute and deliver an indenture
supplemental hereto which shall contain such provisions as shall be deemed
necessary or desirable to confirm that all the rights, powers, trusts and
duties of the predecessor trustee with respect to the Securities of any series
as to which the predecessor trustee is not retiring shall continue to be vested
in the predecessor trustee, and shall add to or change any of the provisions of
this Indenture as shall be necessary to provide for or facilitate the
administration of the trusts hereunder by more than one trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such trustees co-trustees of the same trust and that each such
trustee shall be trustee of a trust or trusts under separate indentures.

                 Upon acceptance of appointment by any successor trustee as
provided in this Section 5.10, the Issuer shall give notice thereof (a) if any
Unregistered Securities of a series affected are then Outstanding, to the
Holders thereof, by publication of such notice at least once in an Authorized
Newspaper in the Borough of Manhattan, The City of New York and at least once
in an Authorized Newspaper in London (and, if required by Section 3.8, at least
once in an Authorized Newspaper in Luxembourg), (b) if any Unregistered
Securities of a series affected are then Outstanding, to the Holders thereof
who have filed their names and addresses with the Trustee pursuant to Section
313(c)(2) of the Trust Indenture Act of 1939, by mailing such notice to such
Holders at such addresses as were so furnished to the Trustee (and the Trustee
shall make such information available to the Issuer for such purpose) and (c)
to the Holders of Registered Securities of each series affected, by mailing
such notice to such Holders at their addresses as they shall appear on the
registry books.  If the acceptance of appointment is substantially
contemporaneous with the resignation, then the notice called for by the
preceding sentence may be combined with the notice called for by Section 5.9.
If the Issuer fails to give such notice within ten days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such
notice to be given at the expense of the Issuer.

                 SECTION 5.11  Merger, Conversion, Consolidation or Succession
to Business of Trustee.  Any corporation into which the Trustee may be merged
or converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all the corporate
trust business of the Trustee, shall be the successor of the Trustee hereunder,
provided that such corporation shall be eligible under the provisions of
Section 5.8, without the execution or filing of any paper or any further





                                       54
   61
act on the part of any of the parties hereto, anything herein to the contrary
notwithstanding.

                 In case at the time such successor to the Trustee shall
succeed to the trusts created by this Indenture any of the Securities of any
series shall have been authenticated but not delivered, any such successor to
the Trustee may adopt the certificate of authentication of any predecessor
trustee and deliver such Securities so authenticated; and, in case at that time
any of the Securities of any series 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 Trustee; and in all
such cases such certificate shall have the full force which it is anywhere in
the Securities of such series or in this Indenture provided that the
certificate of the Trustee shall have; provided, that the right to adopt the
certificate of authentication of any predecessor trustee or to authenticate
Securities of any series in the name of any predecessor trustee shall apply
only to its successor or successors by merger, conversion or consolidation.

                 SECTION 5.12  Appointment of Authenticating Agent.  As long as
any Securities of a series remain Outstanding, the Trustee may, by an
instrument in writing, appoint with the approval of the Issuer an
authenticating agent (the "Authenticating Agent") which shall be authorized to
act on behalf of the Trustee to authenticate Securities, including Securities
issued upon exchange, registration of transfer, partial redemption or pursuant
to Section 2.9.  Securities of each such series authenticated by such
Authenticating Agent shall be entitled to the benefits of this Indenture and
shall be valid and obligatory for all purposes as if authenticated by the
Trustee.  Whenever reference is made in this Indenture to the authentication
and delivery of Securities of any series by the Trustee or to the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
for such series and a certificate of authentication executed on behalf of the
Trustee by such Authenticating Agent.  Such Authenticating Agent shall at all
times be a corporation organized and doing business under the laws of the
United States of America or of any State, authorized under such laws to
exercise corporate trust powers, having a combined capital and surplus of at
least $5,000,000 (determined as provided in Section 5.8 with respect to the
Trustee) and subject to supervision or examination by Federal or State
authority.

                 Any corporation into which any Authenticating Agent may be
merged or converted, or with which it may be consolidated, or any corporation
resulting from any merger, conversion or





                                       55
   62
consolidation to which any Authenticating Agent shall be a party, or any
corporation succeeding to the corporate agency business of any Authenticating
Agent, shall continue to be the Authenticating Agent with respect to all series
of Securities for which it served as Authenticating Agent without the execution
or filing of any paper or any further act on the part of the Trustee or such
Authenticating Agent.

                 Any Authenticating Agent may at any time, and if it shall
cease to be eligible shall, resign by giving written notice of resignation to
the Trustee and to the Issuer.  The Trustee may at any time terminate the
Agency of any Authenticating Agent by giving written notice of termination to
such Authenticating Agent and to the Issuer.  Upon receiving such a notice of
resignation or upon such a termination, or in case at any time any
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 5.12 with respect to one or more series of
Securities, the Trustee may upon receipt of an Issuer Order appoint a successor
Authenticating Agent and the Issuer shall provide notice of such appointment to
all Holders of Securities of such series in the manner and to the extent
provided in Section 5.10.  Any successor Authenticating Agent upon acceptance
of its appointment hereunder shall become vested with all rights, powers,
duties and responsibilities of its predecessor hereunder, with like effect as
if originally named as Authenticating Agent.  The Issuer agrees to pay to the
Authenticating Agent for such series from time to time reasonable compensation.
The Authenticating Agent for the Securities of any series shall have no
responsibility or liability for any action taken by it as such at the direction
of the Trustee.

                 Sections 5.2, 5.3, 5.4, 5.6, 5.8 and 6.3 shall be applicable
to any Authenticating Agent.


                                  ARTICLE SIX


                         CONCERNING THE SECURITYHOLDERS

                 SECTION 6.1  Evidence of Action Taken by Securityholders.  Any
request, demand, authorization, direction, notice, consent, waiver or other
action provided by this Indenture to be given or taken by a specified
percentage in principal amount of the Securityholders of any or all series may
be embodied in and evidenced by one or more instruments of substantially
similar tenor signed by such specified percentage of Securityholders in person
or by agent duly appointed in writing; and, except as herein otherwise
expressly provided, such action shall become effective when such instrument or
instruments





                                       56
   63
are delivered to the Trustee.  Proof of execution of any instrument or of a
writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Sections 5.1 and 5.2) conclusive in favor of the
Trustee and the Issuer, if made in the manner provided in this Article.

                 SECTION 6.2  Proof of Execution of Instruments and of Holding
of Securities.  Subject to Sections 5.1 and 5.2, the execution of any
instrument by a Securityholder or his agent or proxy may be proved in the
following manner:

                 (a)  The fact and date of the execution by any Holder of any
         instrument may be proved by the certificate of any notary public or
         other officer of any jurisdiction authorized to take acknowledgments
         of deeds or administer oaths that the Person executing such
         instruments acknowledged to him the execution thereof, or by an
         affidavit of a witness to such execution sworn to before any such
         notary or other such officer.  Where such execution is by or on behalf
         of any legal entity other than an individual, such certificate or
         affidavit shall also constitute sufficient proof of the authority of
         the Person executing the same.  The fact of the holding by any Holder
         of an Unregistered Security of any series, and the identifying number
         of such Security and the date of his holding the same, may be proved
         by the production of such Security or by a certificate executed by any
         trust company, bank, banker or recognized securities dealer wherever
         situated satisfactory to the Trustee, if such certificate shall be
         deemed by the Trustee to be satisfactory.  Each such certificate shall
         be dated and shall state that on the date thereof a Security of such
         series bearing a specified identifying number was deposited with or
         exhibited to such trust company, bank, banker or recognized securities
         dealer by the Person named in such certificate.  Any such certificate
         may be issued in respect of one or more Unregistered Securities of one
         or more series specified therein.  The holding by the Person named in
         any such certificate of any Unregistered Securities of any series
         specified therein shall be presumed to continue for a period of one
         year from the date of such certificate unless at the time of any
         determination of such holding (1) another certificate bearing a later
         date issued in respect of the same Securities shall be produced, or
         (2) the Security of such series specified in such certificate shall be
         produced by some other Person, or (3) the Security of such series
         specified in such certificate shall have ceased to be Outstanding.
         The fact and date of the execution of any such instrument and the
         amount and numbers of Securities of any series held by the Person so
         executing such instrument and





                                       57
   64
         the amount and numbers of any Security or Securities for such series
         may also be proven in accordance with such reasonable rules and
         regulations as may be prescribed by the Trustee for such series or in
         any other manner which the Trustee for such series may deem
         sufficient.

                 (b)  In the case of Registered Securities, the ownership of
         such Securities shall be proved by the Security register or by a
         certificate of the Security registrar.

                 SECTION 6.3  Holders to be Treated as Owners.  The Issuer, the
Trustee and any agent of the Issuer or the Trustee may deem and treat the
Person in whose name any Security shall be registered upon the Security
register for such series as the absolute owner of such Security (whether or not
such Security shall be overdue and notwithstanding any notation of ownership or
other writing thereon) for the purpose of receiving payment of or on account of
the principal of and, subject to the provisions of this Indenture, interest on
such Security and for all other purposes; and neither the Issuer nor the
Trustee nor any agent of the Issuer or the Trustee shall be affected by any
notice to the contrary.  The Issuer, the Trustee and any agent of the Issuer or
the Trustee may treat the Holder of any Unregistered Security and the Holder of
any Coupon as the absolute owner of such Unregistered Security or Coupon
(whether or not such Unregistered Security or Coupon shall be overdue) for the
purpose of receiving payment thereof or on account thereof and for all other
purposes and neither the Issuer, the Trustee, nor any agent of the Issuer or
the Trustee shall be affected by any notice to the contrary.  All such payments
so made to any such Person, or upon his order, shall be valid, and, to the
extent of the sum or sums so paid, effectual to satisfy and discharge the
liability for moneys payable upon any such Unregistered Security or Coupon.

                 SECTION 6.4  Securities Owned by Issuer Deemed Not
Outstanding.  In determining whether the Holders of the requisite aggregate
principal amount of Outstanding Securities of any or all series have concurred
in any direction, consent or waiver under this Indenture, Securities which are
owned by the Issuer or any other obligor on the Securities with respect to
which such determination is being made or by any Person directly or indirectly
controlling or controlled by or under direct or indirect common control with
the Issuer or any other obligor on the Securities with respect to which such
determination is being made shall be disregarded and deemed not to be
Outstanding for the purpose of any such determination, except that for the
purpose of determining whether the Trustee shall be protected in relying on any
such direction, consent or waiver only Securities which the Trustee knows are
so owned shall be so disregarded.  Securities so owned which have been pledged
in good faith may be





                                       58
   65
regarded as Outstanding if the pledgee establishes to the satisfaction of the
Trustee the pledgee's right so to act with respect to such Securities and that
the pledgee is not the Issuer or any other obligor upon the Securities or any
Person directly or indirectly controlling or controlled by or under direct or
indirect common control with the Issuer or any other obligor on the Securities.
In case of a dispute as to such right, the advice of counsel shall be full
protection in respect of any decision made by the Trustee in accordance with
such advice.  Upon request of the Trustee, the Issuer shall furnish to the
Trustee promptly an Officers' Certificate listing and identifying all
Securities, if any, known by the Issuer to be owned or held by or for the
account of any of the above-described Persons; and, subject to Sections 5.1 and
5.2, the Trustee shall be entitled to accept such Officers' Certificate as
conclusive evidence of the facts therein set forth and of the fact that all
Securities not listed therein are Outstanding for the purpose of any such
determination.

                 SECTION 6.5  Right of Revocation of Action Taken.  At any time
prior to (but not after) the evidencing to the Trustee, as provided in Section
6.1, of the taking of any action by the Holders of the percentage in aggregate
principal amount of the Securities of any or all series, as the case may be,
specified in this Indenture in connection with such action, any Holder of a
Security the serial number of which is shown by the evidence to be included
among the serial numbers of the Securities the Holders of which have consented
to such action may, by filing written notice at the Corporate Trust Office and
upon proof of holding as provided in this Article, revoke such action so far as
concerns such Security.  Except as aforesaid any such action taken by the
Holder of any Security shall be conclusive and binding upon such Holder and
upon all future Holders and owners of such Security and of any Securities
issued in exchange or substitution therefor or on registration of transfer
thereof, irrespective of whether or not any notation in regard thereto is made
upon any such Security.  Any action taken by the Holders of the percentage in
aggregate principal amount of the Securities of any or all series, as the case
may be, specified in this Indenture in connection with such action shall be
conclusively binding upon the Issuer, the Trustee and the Holders of all the
Securities affected by such action.

                            SUPPLEMENTAL INDENTURES


                 SECTION 7.1  Supplemental Indentures Without Consent of
Securityholders.  The Issuer, when authorized by a resolution of its Board of
Directors (which resolution may provide general terms or parameters for such
action and may provide that the specific terms of such action may be determined
in accordance with or pursuant to an Officers' Certificate), and the Trustee
may from time to time and at any time enter into an indenture or indentures
supplemental hereto for one or more of the following purposes:

                 (a)  to convey, transfer, assign, mortgage or pledge to the
         Trustee as security for the Securities of one or more series any
         property or assets;

                 (b)  to evidence the succession of another corporation to the
         Issuer, or successive successions, and the assumption by the successor
         corporation of the covenants, agreements and obligations of the Issuer
         pursuant to Article Eight;

                 (c)  to add to the covenants of the Issuer such further
         covenants, restrictions, conditions or provisions as the Issuer and
         the Trustee shall consider to be for the protection of the Holders of
         Securities or Coupons, and to make the occurrence, or the occurrence
         and continuance, of a default in any such additional covenants,
         restrictions, conditions or provisions an Event of Default permitting
         the enforcement of all or any of the several remedies provided in this
         Indenture as herein set forth; provided, that in respect of any such
         additional covenant, restriction, condition or provision such
         supplemental indenture may provide for a particular period of grace
         after default (which period may be shorter or longer than that allowed
         in the case of other defaults) or may provide for an immediate
         enforcement upon such an Event of Default or may limit the remedies
         available to the Trustee upon such an Event of Default or may limit
         the right of the Holders of a majority in aggregate principal amount
         of the Securities of such series to waive such an Event of Default;

                 (d)  to cure any ambiguity or to correct or supplement any
         provision contained herein or in any supplemental indenture which may
         be defective or inconsistent with any other provision contained herein
         or in any supplemental





                                       60
   67
         indenture, or to make any other provisions as the Issuer may deem
         necessary or desirable, provided that no such action shall materially
         adversely affect the interests of the Holders of the Securities or
         Coupons;

                 (e)  to establish the form or terms of Securities of any
         series or of the Coupons appertaining to such Securities as permitted
         by Sections 2.1 and 2.3; and

                 (f)  to evidence and provide for the acceptance of appointment
         hereunder by a successor trustee with respect to the Securities of one
         or more series 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 hereunder by more than one trustee,
         pursuant to the requirements of Section 5.10.

                 The Trustee is hereby authorized to join with the Issuer in
the execution of any such supplemental indenture, to make any further
appropriate agreements and stipulations which may be therein contained and to
accept the conveyance, transfer, assignment, mortgage or pledge of any property
thereunder, but the Trustee shall not be obligated to enter into any such
supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

                 Any supplemental indenture authorized by the provisions of
this Section may be executed without the consent of the Holders of any of the
Securities at the time Outstanding, notwithstanding any of the provisions of
Section 7.2.

                 SECTION 7.2  Supplemental Indentures With Consent of
Securityholders.  With the consent (evidenced as provided in Article Six) of
the Holders of not less than a majority in aggregate principal amount of the
Securities at the time Outstanding of all series affected by such supplemental
indenture (voting as one class), the Issuer, when authorized by a resolution of
its Board of Directors (which resolution may provide general terms or
parameters for such action and may provide that the specific terms of such
action may be determined in accordance with or pursuant to an Issuer Order),
and the Trustee may, from time to time and at any time, enter into an indenture
or indentures supplemental hereto for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of this
Indenture or of any supplemental indenture or of modifying in any manner the
rights of the Holders of the Securities of each such series or of the Coupons
appertaining to such Securities; provided, that no such supplemental indenture
shall (a) extend the final maturity of any Security, or reduce the principal
amount thereof, or reduce the





                                       61
   68
rate or extend the time of payment of interest thereon, or reduce any amount
payable on redemption thereof, or make the principal thereof (including any
amount in respect of original issue discount) or interest thereon payable in
any coin or currency other than that provided in the Securities and Coupons or
in accordance with the terms thereof, or reduce the amount of the principal of
an Original Issue Discount Security that would be due and payable upon an
acceleration of the maturity thereof pursuant to Section 4.1 or the amount
thereof provable in bankruptcy pursuant to Section 4.2, or alter the provisions
of Section 10.11 or 10.12 or impair or affect the right of any Securityholder
to institute suit for the payment thereof or, if the Securities provide
therefor, any right of repayment at the option of the Securityholder, in each
case without the consent of the Holder of each Security so affected, or (b)
reduce the aforesaid percentage of Securities of any series, the consent of the
Holders of which is required for any such supplemental indenture, without the
consent of the Holders of each Security so affected.

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

                 Upon the request of the Issuer, accompanied by a copy of a
resolution of the Board of Directors (which resolution may provide general
terms or parameters for such action and may provide that the specific terms of
such action may be determined in accordance with or pursuant to an Issuer
Order) certified by the secretary or an assistant secretary of the Issuer
authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of the Holders of the
Securities as aforesaid and other documents, if any, required by Section 6.1,
the Trustee shall join with the Issuer in the execution of such supplemental
indenture unless such supplemental indenture affects the Trustee's own rights,
duties or immunities under this Indenture or otherwise, in which case the
Trustee may in its discretion, but shall not be obligated to, enter into such
supplemental indenture.

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





                                       62
   69
                 Promptly after the execution by the Issuer and the Trustee of
any supplemental indenture pursuant to the provisions of this Section, the
Trustee shall give notice thereof (i) to the Holders of then Outstanding
Registered Securities of each series affected thereby, by mailing a notice
thereof by first-class mail to such Holders at their addresses as they shall
appear on the Security register, (ii) if any Unregistered Securities of a
series affected thereby are then Outstanding, to the Holders thereof who have
filed their names and addresses with the Trustee pursuant to Section 313(c)(2)
of the Trust Indenture Act of 1939, by mailing a notice thereof by first-class
mail to such Holders at such addresses as were so furnished to the Trustee and
(iii) if any Unregistered Securities of a series affected thereby are then
Outstanding, to all Holders thereof, by publication of a notice thereof at
least once in an Authorized Newspaper in the Borough of Manhattan, The City of
New York and at least once in an Authorized Newspaper in London (and, if
required by Section 3.8, at least once in an Authorized Newspaper in
Luxembourg), and in each case such notice shall set forth in general terms the
substance of such supplemental indenture.  Any failure of the Issuer to give
such notice, or any defect therein, shall not, however, in any way impair or
affect the validity of any such supplemental indenture.

                 SECTION 7.3  Effect of Supplemental Indenture.  Upon the
execution of any supplemental indenture pursuant to the provisions hereof, this
Indenture shall be and be deemed to be modified and amended in accordance
therewith and the respective rights, limitations of rights, obligations, duties
and immunities under this Indenture of the Trustee, the Issuer and the Holders
of Securities of each series affected thereby shall thereafter be determined,
exercised and enforced hereunder subject in all respects to such modifications
and amendments, and all the terms and conditions of any such supplemental
indenture shall be and be deemed to be part of the terms and conditions of this
Indenture for any and all purposes.

                 SECTION 7.4  Documents to Be Given to Trustee.  The Trustee,
subject to the provisions of Sections 5.1 and 5.2, may receive an Officers'
Certificate and an Opinion of Counsel as conclusive evidence that any
supplemental indenture executed pursuant to this Article Seven complies with
the applicable provisions of this Indenture.

                 SECTION 7.5  Notation on Securities in Respect of Supplemental
Indentures.  Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to the provisions of this
Article may bear a notation in form approved by the Trustee for such series as
to any matter provided for by such supplemental indenture or as to any action





                                       63
   70
taken by Securityholders.  If the Issuer or the Trustee shall so determine, new
Securities of any series so modified as to conform, in the opinion of the
Trustee and the Board of Directors, to any modification of this Indenture
contained in any such supplemental indenture may be prepared by the Issuer,
authenticated by the Trustee and delivered in exchange for the Securities of
such series then Outstanding.


                                 ARTICLE EIGHT


                   CONSOLIDATION, MERGER, SALE OR CONVEYANCE

                 SECTION 8.1  Issuer May Consolidate, etc., Only on Certain
Terms.  The Issuer shall not consolidate with or merge into any other
corporation or convey, transfer or lease its properties and assets
substantially as an entirety to any Person, unless:

                 (a)  the corporation formed by such consolidation or into
         which the Issuer is merged or the Person which acquires by conveyance,
         transfer or lease the properties and assets of the Issuer
         substantially as an entirety shall expressly assume, by a supplemental
         indenture hereto, executed and delivered to the Trustee, in form
         satisfactory to the Trustee, the due and punctual payment of the
         principal of and interest on all the Securities and Coupons, if any,
         according to their tenor, and the performance of every covenant of
         this Indenture on the part of the Issuer to be performed or observed;

                 (b)  immediately after giving effect to such transaction, no
         Event of Default, and no event which, after notice or lapse of time,
         or both, would become an Event of Default, shall have happened and be
         continuing;

                 (c)  the Issuer has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel each stating that such
         consolidation, merger, conveyance, transfer or lease and such
         supplemental indenture comply with this Article and that all
         conditions precedent herein provided for relating to such transaction
         have been complied with; and

                 (d)  the Issuer has delivered to the Trustee such other
         documents as the Trustee may, in its discretion, reasonably require.

                 SECTION 8.2  Successor Corporation Substituted.  In case of
any such consolidation, merger, sale, lease or conveyance, and following such
an assumption by the successor Person, such successor Person shall succeed to
and be substituted for the Issuer, with the same effect as if it had been named
herein.  Such successor Person may cause to be signed, and may issue either in
its own name or in the name of the Issuer prior to such succession any or all
of the Securities issuable hereunder which together with any Coupons
appertaining thereto theretofore shall not have been signed by the Issuer and
delivered to the Trustee; and, upon the order of such successor Person, instead
of the Issuer, and subject to all the terms, conditions and limitations in this
Indenture prescribed, the Trustee shall authenticate and shall deliver any
Securities together with any Coupons appertaining thereto which previously
shall have been signed and delivered by the officers of the Issuer to the
Trustee for authentication, and any Securities which such successor Person
thereafter shall cause to be signed and delivered to the Trustee for that
purpose.  All of the Securities so issued together with any Coupons
appertaining thereto shall in all respects have the same legal rank and benefit
under this Indenture as the Securities theretofore or thereafter issued in
accordance with the terms of this Indenture as though all of such Securities
had been issued at the date of the execution hereof.

                 In case of any such consolidation, merger, sale, lease or
conveyance such changes in phrasing and form (but not in substance) may be made
in the Securities and Coupons thereafter to be issued as may be appropriate.

                 In the event of any such sale or conveyance (other than a
conveyance by way of lease) the Issuer or any successor Person which shall
theretofore have become such in the manner described in this Article shall be
discharged from all obligations and covenants under this Indenture and the
Securities and may be liquidated and dissolved.

                 SECTION 9.1  Satisfaction and Discharge of Indenture.  (A)  If
at any time (a) the Issuer shall have paid or caused to be paid the principal
of and interest on all the Securities of any series Outstanding hereunder and
all unmatured Coupons





                                       65
   72
appertaining thereto (other than Securities of such series and Coupons
appertaining thereto which have been destroyed, lost or stolen and which have
been replaced or paid as provided in Section 2.9) as and when the same shall
have become due and payable, or (b) the Issuer shall have delivered to the
Trustee for cancellation all Securities of any series theretofore authenticated
and all unmatured Coupons appertaining thereto (other than any Securities of
such series and Coupons appertaining thereto which shall have been destroyed,
lost or stolen and which shall have been replaced or paid as provided in
Section 2.9) or (c) in the case of any series of Securities where the exact or
maximum amount (including the currency of payment) of principal of and interest
due on which can be determined at the time of making the deposit referred to in
clause (ii) below, (i) all the Securities of such series and all unmatured
Coupons appertaining thereto not theretofore delivered to the Trustee for
cancellation shall have become due and payable, or are by their terms to become
due and payable within one year or are to be called for redemption within one
year under arrangements satisfactory to the Trustee for the giving of notice of
redemption, and (ii) the Issuer shall have irrevocably deposited or caused to
be deposited with the Trustee as trust funds the entire amount in cash (other
than moneys repaid by the Trustee or any paying agent to the Issuer in
accordance with Section 9.4) or, in the case of any series of Securities the
payments on which may only be made in Dollars, direct obligations of the United
States of America, backed by its full faith and credit ("U.S. Government
Obligations"), maturing as to principal and interest at such times and in such
amounts as will insure the availability of cash, or a combination thereof,
sufficient in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the
Trustee, to pay (A) the principal and interest on all Securities of such series
and Coupons appertaining thereto on each date that such principal or interest
is due and payable and (B) any mandatory sinking fund payments on the dates on
which such payments are due and payable in accordance with the terms of the
Indenture and the Securities of such series; and if, in any such case, the
Issuer shall also pay or cause to be paid all other sums payable hereunder by
the Issuer with respect to the Securities of such series, then this Indenture
with respect to the Securities of such series shall cease to be of further
effect (except as to (i) rights of registration of transfer and exchange of
Securities of such series and of Coupons appertaining thereto and the Issuer's
right of optional redemption, if any, (ii) substitution of mutilated, defaced,
destroyed, lost or stolen Securities or Coupons, (iii) rights of Holders of
Securities and Coupons appertaining thereto to receive payments of principal
thereof and interest thereon, upon the original stated due dates therefor (but
not upon acceleration), and remaining rights of the





                                       66
   73
Holders to receive mandatory sinking fund payments, if any, (iv) the rights,
obligations, duties and immunities of the Trustee hereunder, (v) the rights of
the Holders of Securities of such series and Coupons appertaining thereto as
beneficiaries hereof with respect to the property so deposited with the Trustee
payable to all or any of them, and (vi) the obligations of the Issuer under
Section 3.2) and the Trustee, on demand of the Issuer accompanied by an
Officers' Certificate and an Opinion of Counsel and at the cost and expense of
the Issuer, shall execute proper instruments acknowledging such satisfaction of
and discharging this Indenture with respect to the Securities of such series;
provided, that the rights of Holders of the Securities and Coupons to receive
amounts in respect of principal of and interest on the Securities and Coupons
held by them shall not be delayed longer than required by then-applicable
mandatory rules or policies of any securities exchange upon which the
Securities are listed.  The Issuer agrees to reimburse the Trustee for any
costs or expenses thereafter reasonably and properly incurred and to compensate
the Trustee for any services thereafter reasonably and properly rendered by the
Trustee in connection with this Indenture or the Securities of such series.

                 (B)  The following provisions shall apply to the Securities of
each series unless specifically otherwise provided in a Board Resolution,
Officers' Certificate or indenture supplemental hereto provided pursuant to
Section 2.3.  In addition to discharge of the Indenture pursuant to the next
preceding paragraph, in the case of any series of Securities the exact or
maximum amounts (including the currency of payment) of principal of and
interest due on which can be determined at the time of making the deposit
referred to in clause (a) below, the Issuer shall be deemed to have paid and
discharged the entire indebtedness on all the Securities of such a series and
the Coupons appertaining thereto on the 91st day after the date of the deposit
referred to in subparagraph (a) below, and the provisions of this Indenture
with respect to the Securities of such series and Coupons appertaining thereto
shall no longer be in effect (except as to (i) rights of registration of
transfer and exchange of Securities of such series and of Coupons appertaining
thereto and the Issuer's right of optional redemption, if any, (ii)
substitution of mutilated, defaced, destroyed, lost or stolen Securities or
Coupons, (iii) rights of Holders of Securities and Coupons appertaining thereto
to receive payments of principal thereof and interest thereon, upon the
original stated due dates therefor (but not upon acceleration), and remaining
rights of the Holders to receive mandatory sinking fund payments, if any, (iv)
the rights, obligations, duties and immunities of the Trustee hereunder, (v)
the rights of the Holders of Securities of such series and Coupons appertaining
thereto as beneficiaries hereof with respect to the property so





                                       67
   74
deposited with the Trustee payable to all or any of them and (vi) the
obligations of the Issuer under Section 3.2) and the Trustee, at the expense of
the Issuer, shall at the Issuer's request, execute proper instruments
acknowledging the same, if

                 (a)  with reference to this provision the Issuer has
         irrevocably deposited or caused to be irrevocably deposited with the
         Trustee as trust funds in trust, specifically pledged as security for,
         and dedicated solely to, the benefit of the Holders of the Securities
         of such series and Coupons appertaining thereto (i) cash in an amount,
         or (ii) in the case of any series of Securities the payments on which
         may only be made in Dollars, U.S.  Government Obligations, maturing as
         to principal and interest at such times and in such amounts as will
         insure the availability of cash or (iii) a combination thereof,
         sufficient, in the opinion of a nationally recognized firm of
         independent public accountants expressed in a written certification
         thereof delivered to the Trustee, to pay (A) the principal and
         interest on all Securities of such series and Coupons appertaining
         thereto on each date that such principal or interest is due and
         payable and (B) any mandatory sinking fund payments on the dates on
         which such payments are due and payable in accordance with the terms
         of the Indenture and the Securities of such series;

                 (b)  such deposit will not result in a breach or violation of,
         or constitute a default under, any agreement or instrument to which
         the Issuer is a party or by which it is bound;

                 (c)  the Issuer has delivered to the Trustee an Opinion of
         Counsel based on the fact that (x) the Issuer has received from, or
         there has been published by, the Internal Revenue Service a ruling or
         (y) since the date hereof, there has been a change in the applicable
         Federal income tax law, in either case to the effect that, and such
         opinion shall confirm that, the Holders of the Securities of such
         series and Coupons appertaining thereto will not recognize income,
         gain or loss for Federal income tax purposes as a result of such
         deposit, defeasance and discharge and will be subject to Federal
         income tax on the same amounts, in the same manner and at the same
         times, as would have been the case if such deposit, defeasance and
         discharge had not occurred;

                 (d)  the Issuer has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all
         conditions precedent provided for relating to the defeasance
         contemplated by this provision have been complied with.

   75
                 (e)  no Event of Default or event which with notice or lapse
         of time or both would become an Event of Default with respect to the
         Securities shall have occurred and be continuing on the date of such
         deposit or, insofar as subsections 4.1(d) and (e) are concerned, at
         any time during the period ending on the 91st day after the date of
         such deposit (it being understood that this condition shall not be
         deemed satisfied until the expiration of such period); and

                 (f)  Such covenant defeasance contemplated by this provision
         shall not cause any Securities then listed on any registered national
         securities exchange under the Securities Exchange Act of 1934, as
         amended, to be delisted.

                 (C)  The following provisions shall apply to the Securities of
each series unless specifically otherwise provided in a Board Resolution,
Officers' Certificate or indenture supplemental hereto provided pursuant to
Section 2.3.  In the case of any series of Securities the exact or maximum
amounts (including the currency of payment) of principal of and interest due on
which can be determined at the time of making the deposit referred to in clause
(a) below, the Issuer shall be released from its obligations under Sections
3.6, 3.7 and 8.1 with respect to the Securities of any such series, and any
Coupons appertaining thereto, Outstanding on and after the date the conditions
set forth below are satisfied (hereinafter, "covenant defeasance").  For this
purpose, such covenant defeasance means that, with respect to the Outstanding
Securities of any series, the Issuer may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in such
Sections, whether directly or indirectly by reason of any reference elsewhere
herein to such Sections or by reason of any reference in such Sections to any
other provision herein or in any other document and such omission to comply
shall not constitute an Event of Default under Section 4.1, but the remainder
of this Indenture and such Securities and Coupons shall be unaffected thereby.
The following shall be the conditions to application of this subsection C of
this Section 9.1:

                 (a)  The Issuer has irrevocably deposited or caused to be
         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 the Securities
         of such series and Coupons appertaining thereto, (i) cash in an
         amount, or (ii) in the case of any series of Securities the payments
         on which may only be made in Dollars, U.S. Government Obligations
         maturing as to principal and interest at such times and in such
         amounts as will insure the availability of





                                       69
   76
         cash or (iii) a combination thereof, sufficient, in the opinion of a
         nationally recognized firm of independent public accountants expressed
         in a written certification thereof delivered to the Trustee, to pay
         (A) the principal and interest on all Securities of such series and
         Coupons appertaining thereto on each date that such principal and
         interest is due and payable and (B) any mandatory sinking fund
         payments on the day on which such payments are due and payable in
         accordance with the terms of the Indenture and the Securities of such
         series.

                 (b)  No Event of Default or event which with notice or lapse
         of time or both would become an Event of Default with respect to the
         Securities shall have occurred and be continuing on the date of such
         deposit or, insofar as subsections 4.1(d) and (e) are concerned, at
         any time during the period ending on the 91st day after the date of
         such deposit (it being understood that this condition shall not be
         deemed satisfied until the expiration of such period).

                 (c)  Such covenant defeasance shall not cause the Trustee to
         have a conflicting interest as described in Section 310 of the Trust
         Indenture Act of 1939 with respect to any securities of the Issuer.

                 (d)  Such covenant defeasance shall not result in a breach or
         violation of, or constitute a default under, this Indenture or any
         other agreement or instrument to which the Issuer is a party or by
         which it is bound.

                 (e)  Such covenant defeasance shall not cause any Securities
         then listed on any registered national securities exchange under the
         Securities Exchange Act of 1934, as amended, to be delisted.

                 (f)  The Issuer shall have delivered to the Trustee an
         Officers' Certificate and Opinion of Counsel to the effect that the
         Holders of the Securities of such series and Coupons appertaining
         thereto will not recognize income, gain or loss for Federal income tax
         purposes as a result of such covenant defeasance and will be subject
         to Federal income tax on the same amounts, in the same manner and at
         the same times as would have been the case if such covenant defeasance
         had not occurred.

                 (g)  The Issuer shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that all
         conditions precedent provided for relating to the covenant defeasance
         contemplated by this provision have been complied with.

                 SECTION 9.2  Application by Trustee of Funds Deposited for
Payment of Securities.  Subject to Section 9.4, all moneys deposited with the
Trustee (or other trustee) pursuant to Section 9.1 shall be held in trust and
applied by it to the payment, either directly or through any paying agent
(including the Issuer acting as its own paying agent), to the Holders of the
particular Securities of such series and of Coupons appertaining thereto for
the payment or redemption of which such moneys have been deposited with the
Trustee, of all sums due and to become due thereon for principal and interest;
but such money need not be segregated from other funds except to the extent
required by law.

                 SECTION 9.3  Repayment of Moneys Held by Paying Agent.  In
connection with the satisfaction and discharge of this Indenture with respect
to Securities of any series, all moneys then held by any paying agent under the
provisions of this Indenture with respect to such series of Securities shall,
upon demand of the Issuer, be repaid to it or paid to the Trustee and thereupon
such paying agent shall be released from all further liability with respect to
such moneys.

                 SECTION 9.4  Return of Moneys Held by Trustee and Paying Agent
Unclaimed for Two Years.  Any moneys deposited with or paid to the Trustee or
any paying agent for the payment of the principal of or interest on any
Security of any series or Coupons attached thereto and not applied but
remaining unclaimed for two years after the date upon which such principal or
interest shall have become due and payable, shall, upon the written request of
the Issuer and unless otherwise required by mandatory provisions of applicable
escheat or abandoned or unclaimed property law, be repaid to the Issuer by the
Trustee for such series or such paying agent, and the Holder of the Securities
of such series and of any Coupons appertaining thereto shall, unless otherwise
required by mandatory provisions of applicable escheat or abandoned or
unclaimed property laws, thereafter look only to the Issuer for any payment
which such Holder may be entitled to collect, and all liability of the Trustee
or any paying agent with respect to such moneys shall thereupon cease;
provided, however, that the Trustee or such paying agent, before being required
to make any such repayment with respect to moneys deposited with it for any
payment (a) in respect of Registered Securities of any series, shall at the
expense of the Issuer, mail by first-class mail to Holders of such Securities
at their addresses as they shall appear on the Security register, and (b) in
respect of Unregistered Securities of any series, shall at the expense of the
Issuer cause to be published once, in an Authorized Newspaper in the Borough of
Manhattan, The City of New York and once in an Authorized Newspaper in London
(and if required by Section 3.8, once in an Authorized Newspaper in





                                       71
   78
Luxembourg), notice, that such moneys remain and that, after a date specified
therein, which shall not be less than 30 days from the date of such mailing or
publication, any unclaimed balance of such money then remaining  will be repaid
to the Issuer.

                 SECTION 9.5  Indemnity for U.S. Government Obligations.  The
Issuer shall pay and indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against the U.S. Government Obligations deposited
pursuant to Section 9.1 or the principal or interest received in respect of
such obligations.

                 SECTION 9.6  Excess Funds.  The Trustee shall deliver to the
Issuer from time to time upon Issuer Order any U.S. Government Obligations or
money held by it as provided in Section 9.1 which, as expressed in the opinion
of a nationally recognized firm of independent public accountants expressed in
a written certification thereof delivered to the Trustee (which may include the
applicable such opinion delivered to the Trustee pursuant to Section 9.1), are
then in excess of the amount thereof which then would have been required to be
deposited for the purpose for which such obligations or money were deposited or
received.

                            MISCELLANEOUS PROVISIONS


                 SECTION 10.1  Incorporators, Stockholders, Officers and
Directors of Issuer Exempt from Individual Liability.  No recourse under or
upon any obligation, covenant or agreement contained in this Indenture, or in
any Security, or because of any indebtedness evidenced thereby, shall be had
against any incorporator, as such or against any past, present or future
stockholder, officer or director, as such, of the Issuer or of any successor,
either directly or through the Issuer or any successor, under any rule of law,
statute or constitutional provision or by the enforcement of any assessment or
by any legal or equitable proceeding or otherwise, all such liability being
expressly waived and released by the acceptance of the Securities and the
Coupons appertaining thereto by the Holders thereof and as part of the
consideration for the issue of the Securities and the Coupons appertaining
thereto.

                 SECTION 10.2  Provisions of Indenture for the Sole Benefit of
Parties and Holders of Securities and Coupons.  Nothing in this Indenture, in
the Securities or in the Coupons appertaining thereto, expressed or implied,
shall give or be construed to give to any Person, other than the parties hereto





                                       72
   79
and their successors and the Holders of the Securities or Coupons, if any, any
legal or equitable right, remedy or claim under this Indenture or under any
covenant or provision herein contained, all such covenants and provisions being
for the sole benefit of the parties hereto and their successors and of the
Holders of the Securities or Coupons, if any.

                 SECTION 10.3  Successors and Assigns of Issuer Bound by
Indenture.  All the covenants, stipulations, promises and agreements in this
Indenture contained by or in behalf of the Issuer shall bind its successors and
assigns, whether so expressed or not.

                 SECTION 10.4  Notices and Demands on Issuer, Trustee and
Holders of Securities and Coupons.  Any notice or demand which by any provision
of this Indenture is required or permitted to be given or served by the Trustee
or by the Holders of Securities or Coupons to or on the Issuer may be given or
served by being deposited postage prepaid, first-class mail (except as
otherwise specifically provided herein) addressed (until another address of the
Issuer is filed by the Issuer with the Trustee) to Northwest Pipeline
Corporation, 295 Chipera Way, Salt Lake City, Utah 84158-0900, Attention:
Treasurer.  Any notice, direction, request or demand by the Issuer or any
Holder of Securities or Coupons to or upon the Trustee shall be deemed to have
been sufficiently given or served by being deposited postage prepaid,
first-class mail (except as otherwise specifically provided herein) addressed
(until another address of the Trustee is filed by the Trustee with the Issuer)
to Chemical Bank, 450 West 33rd Street, New York, New York 10001, Attention:
Corporate Trustee Administration Department.

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

                 In case, by reason of the suspension of or





                                       73
   80
irregularities in regular mail service, it shall be impracticable to mail
notice to the Issuer when such notice is required to be given pursuant to any
provision of this Indenture, then any manner of giving such notice as shall be
reasonably satisfactory to the Trustee shall be deemed to be a sufficient
giving of such notice.

                 SECTION 10.5  Officers' Certificates and Opinions of Counsel;
Statements to Be Contained Therein.  Upon any application or demand by the
Issuer to the Trustee to take any action under any of the provisions of this
Indenture, the Issuer shall furnish to the Trustee an Officers' Certificate
stating that all conditions precedent provided for in this Indenture relating
to the proposed action have been complied with and an Opinion of Counsel
stating that in the opinion of such counsel all such conditions precedent have
been complied with, except that in the case of any such application or demand
as to which the furnishing of such documents is specifically required by any
provision of this Indenture relating to such particular application or demand,
no additional certificate or opinion need be furnished.

                 Each certificate or opinion provided for in this Indenture and
delivered to the Trustee with respect to compliance with a condition or
covenant provided for in this Indenture shall include (a) a statement that the
person making such certificate or opinion has read such covenant or condition,
(b) a brief statement as to the nature and scope of the examination or
investigation upon which the statements or opinions contained in such
certificate or opinion are based, (c) a statement that, in the opinion of such
person, he has made such examination or investigation as is necessary to enable
him to express an opinion as to whether or not such covenant or condition has
been complied with and (d) a statement as to whether or not, in the opinion of
such person, such condition or covenant has been complied with.

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





                                       74
   81
certificate, statement or opinion may be based as aforesaid are erroneous, or
in the exercise of reasonable care should know that the same are erroneous.

                 Any certificate, statement or opinion of an officer of the
Issuer or of counsel may be based, insofar as it relates to accounting matters,
upon a certificate or opinion of or representations by an accountant or firm of
accountants in the employ of the Issuer, unless such officer or counsel, as the
case may be, knows that the certificate or opinion or representations with
respect to the accounting matters upon which his certificate, statement or
opinion may be based as aforesaid are erroneous, or in the exercise of
reasonable care should know that the same are erroneous.

                 Any certificate or opinion of any independent firm of public
accountants filed with and directed to the Trustee shall contain a statement
that such firm is independent.

                 SECTION 10.6  Payments Due on Saturdays, Sundays and Holidays.
If the date of maturity of interest on or principal of the Securities of any
series or any Coupons appertaining thereto or the date fixed for redemption or
repayment of any such Security or Coupon shall not be a Business Day, then
payment of interest or principal need not be made on such date, but may be made
on the next succeeding Business Day with the same force and effect as if made
on the date of maturity or the date fixed for redemption or repayment, and no
interest shall accrue for the period after such date.

                 SECTION 10.7  Conflict of Any Provision of Indenture with
Trust Indenture Act of 1939.  If and to the extent that any provision of this
Indenture limits, qualifies or conflicts with another provision included in
this Indenture by operation of Sections 310 to 317, inclusive, of the Trust
Indenture Act of 1939 (an "incorporated provision"), such incorporated
provision shall control.

                 SECTION 10.8  New York Law to Govern.  This Indenture and each
Security and Coupon shall be deemed to be a contract under the laws of the
State of New York, and for all purposes shall be construed in accordance with
the laws of such State, except as may otherwise be required by mandatory
provisions of law.

                 SECTION 10.9  Counterparts.  This Indenture may be executed in
any number of counterparts, each of which shall be an original; but such
counterparts shall together constitute but one and the same instrument.

                 SECTION 10.10  Effect of Headings.  The Article and Section
headings herein and the Table of Contents are for convenience only and shall
not affect the construction hereof.

                 SECTION 10.11  Securities in a Foreign Currency or in ECU.
Unless otherwise specified in an Officers' Certificate delivered pursuant to
Section 2.3 of this Indenture with respect to a particular series of
Securities, whenever for purposes of this Indenture any action may be taken by
the Holders of a specified percentage in aggregate principal amount of
Securities of all series or all series affected by a particular action at the
time Outstanding and, at such time, there are Outstanding Securities of any
series which are denominated in a coin or currency other than Dollars
(including ECUs), then the principal amount of Securities of such series which
shall be deemed to be Outstanding for the purpose of taking such action shall
be that amount of Dollars that could be obtained for such amount at the Market
Exchange Rate.  For purposes of this Section 10.11, Market Exchange Rate shall
mean the noon Dollar buying rate in New York City for cable transfers of that
currency as published by the Federal Reserve Bank of New York; provided,
however, in the case of ECUs, Market Exchange Rate shall mean the rate of
exchange determined by the Commission of the European Communities (or any
successor thereto) as published in the Official Journal of the European
Communities (such publication or any successor publication, the "Journal").  If
such Market Exchange Rate is not available for any reason with respect to such
currency, the Trustee shall use, in its sole discretion and without liability
on its part, such quotation of the Federal Reserve Bank of New York or, in the
case of ECUs, the rate of exchange as published in the Journal, as of the most
recent available date, or quotations or, in the case of ECUs, rates of exchange
from one or more major banks in The City of New York or in the country of issue
of the currency in question, which for purposes of the ECU shall be Brussels,
Belgium, or such other quotations or, in the case of ECU, rates of exchange as
the Trustee shall deem appropriate.  The provisions of this paragraph shall
apply in determining the equivalent principal amount in respect of Securities
of a series denominated in a currency other than Dollars in connection with any
action taken by Holders of Securities pursuant to the terms of this Indenture.

                 All decisions and determinations of the Trustee regarding the
Market Exchange Rate or any alternative determination provided for in the
preceding paragraph shall be in its sole discretion and shall, in the absence
of manifest error, be conclusive to the extent permitted by law for all
purposes and irrevocably binding upon the Issuer and all Holders.

   83
                 SECTION 10.12  Judgment Currency.  The Issuer agrees, to the
fullest extent that it may effectively do so under applicable law, that (a) if
for the purpose of obtaining judgment in any court it is necessary to convert
the sum due in respect of the principal of or interest on the Securities of any
series (the "Required Currency") into a currency in which a judgment will be
rendered (the "Judgment Currency"), the rate of exchange used shall be the rate
at which in accordance with normal banking procedures the Trustee could
purchase in The City of New York the Required Currency with the Judgment
Currency on the day on which a final unappealable judgment is entered, unless
such day is not a New York Banking Day, then, to the extent permitted by
applicable law, the rate of exchange used shall be the rate at which in
accordance with normal banking procedures the Trustee could purchase in The
City of New York the Required Currency with the Judgment Currency on the New
York Banking Day preceding the day on which a final unappealable judgment is
entered, and (b) its obligations under this Indenture to make payments in the
Required Currency (i) shall not be discharged or satisfied by any tender, or
any recovery pursuant to any judgment (whether or not entered in accordance
with subsection (a)), in any currency other than the Required Currency, except
to the extent that such tender or recovery shall result in the actual receipt,
by the payee, of the full amount of the Required Currency expressed to be
payable in respect of such payments, (ii) shall be enforceable as an
alternative or additional cause of action for the purpose of recovering in the
Required Currency the amount, if any, by which such actual receipt shall fall
short of the full amount of the Required Currency so expressed to be payable
and (iii) shall not be affected by judgment being obtained for any other sum
due under this Indenture.  For purposes of the foregoing, "New York Banking
Day" means any day except a Saturday, Sunday or a legal holiday in The City of
New York or a day on which banking institutions in The City of New York are
authorized or required by law or executive order to close.

                                 ARTICLE ELEVEN


                   REDEMPTION OF SECURITIES AND SINKING FUNDS


                 SECTION 11.1  Applicability of Article.  The provisions of
this Article shall be applicable to the Securities of any series which are
redeemable before their maturity or to any sinking fund for the retirement of
Securities of a series except as otherwise specified as contemplated by Section
2.3 for Securities of such series.

                 SECTION 11.2  Notice of Redemption; Partial Redemptions.
Notice of redemption to the Holders of Registered Securities of any series to
be redeemed as a whole or in part at the option of the Issuer shall be given by
mailing notice of such redemption by first class mail, postage prepaid, at
least 30 days and not more than 60 days prior to the date fixed for redemption
to such Holders of Securities of such series at their last addresses as they
shall appear upon the registry books.  Notice of redemption to the Holders of
Unregistered Securities to be redeemed as a whole or in part, who have filed
their names and addresses with the Trustee pursuant to Section 313(c)(2) of the
Trust Indenture Act of 1939, shall be given by mailing notice of such
redemption, by first class mail, postage prepaid, at least 30 days and not more
than 60 prior to the date fixed for redemption, to such Holders at such
addresses as were so furnished to the Trustee (and, in the case of any such
notice given by the Issuer, the Trustee shall make such information available
to the Issuer for such purpose).  Notice of redemption to all other Holders of
Unregistered Securities shall be published in an Authorized Newspaper in the
Borough of Manhattan, The City of New York and in an Authorized Newspaper in
London (and, if required by Section 3.8, in an Authorized Newspaper in
Luxembourg), in each case, once in each of three successive calendar weeks, the
first publication to be not less than 30 nor more than 60 days prior to the
date fixed for redemption.  Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not
the Holder receives the notice.  Failure to give notice by mail, or any defect
in the notice to the Holder of any Security of a series designated for
redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other Security of such series.

                 The notice of redemption to each such Holder shall specify the
principal amount of each Security of such series held by such Holder to be
redeemed, the date fixed for redemption, the





                                       78
   85
redemption price, the numbers of the certificate for such Security being
redeemed, the place or places of payment, that payment will be made upon
presentation and surrender of such Securities and, in the case of Securities
with Coupons attached thereto, of all Coupons appertaining thereto maturing
after the date fixed for redemption, that such redemption is pursuant to the
mandatory or optional sinking fund, or both, if such be the case, that interest
accrued to the date fixed for redemption will be paid as specified in such
notice and that on and after said date interest thereon or on the portions
thereof to be redeemed will cease to accrue.  In case any Security of a series
is to be redeemed in part only the notice of redemption shall state the portion
of the principal amount thereof to be redeemed and shall state that on and
after the date fixed for redemption, upon surrender of such Security, a new
Security or Securities of such series in principal amount equal to the
unredeemed portion thereof will be issued.

                 The notice of redemption of Securities of any series to be
redeemed at the option of the Issuer shall be given by the Issuer or, at the
Issuer's request, by the Trustee in the name and at the expense of the Issuer.

                 On or before the redemption date specified in the notice of
redemption given as provided in this Section, the Issuer will deposit with the
Trustee or with one or more paying agents (or, if the Issuer is acting as its
own paying agent, set aside, segregate and hold in trust as provided in Section
3.4) an amount of money sufficient to redeem on the redemption date all the
Securities of such series so called for redemption at the appropriate
redemption price, together with accrued interest to the date fixed for
redemption.  The Issuer will deliver to the Trustee at least 70 days prior to
the date fixed for redemption an Officers' Certificate stating the aggregate
principal amount of Securities to be redeemed.  In case of a redemption at the
election of the Issuer prior to the expiration of any restriction on such
redemption or subject to compliance with a condition precedent, the Issuer
shall deliver to the Trustee, prior to the giving of any notice of redemption
to Holders pursuant to this Section, an Officers' Certificate stating that such
restriction or condition precedent has been complied with.

                 If less than all the Securities of a series are to be
redeemed, the Trustee shall select, in such manner as it shall deem appropriate
and fair, Securities of such series to be redeemed in whole or in part.
Securities may be redeemed in part in multiples equal to the minimum authorized
denomination for Securities of such series or any multiple thereof.  The
Trustee shall promptly notify the Issuer in writing of the Securities of such
series selected for redemption and, in the case of any





                                       79
   86
Securities of such series selected for partial redemption, the principal amount
thereof to be redeemed.  For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to the redemption of Securities of
any series shall relate, in the case of any Security redeemed or to be redeemed
only in part, to the portion of the principal amount of such Security which has
been or is to be redeemed.

                 SECTION 11.3  Payment of Securities Called for Redemption.  If
notice of redemption has been given as above provided, the Securities or
portions of Securities specified in such notice shall become due and payable on
the date and at the place stated in such notice at the applicable redemption
price, together with interest accrued to the date fixed for redemption, and on
and after said date (unless the Issuer shall default in the payment of such
Securities at the redemption price, together with interest accrued to said
date) interest on the Securities or portions of Securities so called for
redemption shall cease to accrue, and the unmatured Coupons, if any,
appertaining thereto shall be void, and, except as provided in Sections 5.5 and
9.4, such Securities shall cease from and after the date fixed for redemption
to be entitled to any benefit or security under this Indenture, and the Holders
thereof shall have no right in respect of such Securities except the right to
receive the redemption price thereof and unpaid interest to the date fixed for
redemption.  On presentation and surrender of such Securities at a place of
payment specified in said notice, together with all Coupons, if any,
appertaining thereto maturing after the date fixed for redemption, said
Securities or the specified portions thereof shall be paid and redeemed by the
Issuer at the applicable redemption price, together with interest accrued
thereon to the date fixed for redemption; provided that payment of interest
becoming due on or prior to the date fixed for redemption shall be payable in
the case of Securities with Coupons attached thereto, to the Holders of the
Coupons for such interest upon surrender thereof, and in the case of Registered
Securities, to the Holders of such Registered Securities registered as such on
the relevant record date subject to the terms and provisions of Sections 2.3
and 2.7 hereof.

                 If any Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal shall, until paid or duly
provided for, bear interest from the date fixed for redemption at the rate of
interest or Yield to Maturity (in the case of an Original Issue Discount
Security) borne by such Security.

                 If any Security with Coupons attached thereto is surrendered
for redemption and is not accompanied by all appurtenant Coupons maturing after
the date fixed for redemption,





                                       80
   87
the surrender of such missing Coupon or Coupons may be waived by the Issuer and
the Trustee, if there be furnished to each of them such security or indemnity
as they may require to save each of them harmless.

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

                 SECTION 11.4  Exclusion of Certain Securities from Eligibility
for Selection for Redemption.  Securities shall be excluded from eligibility
for selection for redemption if they are identified by registration and
certificate number in an Officers' Certificate delivered to the Trustee at
least 40 days prior to the last date on which notice of redemption may be given
as being owned of record and beneficially by, and not pledged or hypothecated
by either (a) the Issuer or (b) an entity specifically identified in such
written statement as directly or indirectly controlling or controlled by or
under direct or indirect common control with the Issuer.

                 SECTION 11.5  Mandatory and Optional Sinking Funds.  The
minimum amount of any sinking fund payment provided for by the terms of the
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 the Securities of any series is herein referred to as an "optional
sinking fund payment".  The date on which a sinking fund payment is to be made
is herein referred to as the "sinking fund payment date".

                 In lieu of making all or any part of any mandatory sinking
fund payment with respect to any series of Securities in cash, the Issuer may
at its option (a) deliver to the Trustee Securities of such series theretofore
purchased or otherwise acquired (except upon redemption pursuant to the
mandatory sinking fund) by the Issuer or receive credit for Securities of such
series (not previously so credited) theretofore purchased or otherwise acquired
(except as aforesaid) by the Issuer and delivered to the Trustee for
cancellation pursuant to Section 2.10, (b) receive credit for optional sinking
fund payments (not previously so credited) made pursuant to this Section, or
(c) receive credit for Securities of such series (not previously so credited)
redeemed by the Issuer through any optional redemption provision contained in
the terms of such series.  Securities so delivered or credited shall be
received or credited by the Trustee at the sinking fund redemption price
specified in such





                                       81
   88
Securities.

                 On or before the 60th day next preceding each sinking fund
payment date for any series, the Issuer will deliver to the Trustee an
Officers' Certificate (which need not contain the statements required by
Section 10.5) (a) specifying the portion of the mandatory sinking fund payment
to be satisfied by payment of cash and the portion to be satisfied by credit of
Securities of such series and the basis for such credit, (b) stating that none
of the Securities of such series has theretofore been so credited, (c) stating
that no defaults in the payment of interest or Events of Default with respect
to such series have occurred (which have not been waived or cured) and are
continuing and (d) stating whether or not the Issuer intends to exercise its
right to make an optional sinking fund payment with respect to such series and,
if so, specifying the amount of such optional sinking fund payment which the
Issuer intends to pay on or before the next succeeding sinking fund payment
date.  Any Securities of such series to be credited and required to be
delivered to the Trustee in order for the Issuer to be entitled to credit
therefor as aforesaid which have not theretofore been delivered to the Trustee
shall be delivered for cancellation pursuant to Section 2.10 to the Trustee
with such Officers' Certificate (or reasonably promptly thereafter if
acceptable to the Trustee).  Such Officers' Certificate shall be irrevocable
and upon its receipt by the Trustee the Issuer shall become unconditionally
obligated to make all the cash payments or payments therein referred to, if
any, on or before the next succeeding sinking fund payment date.  Failure of
the Issuer, on or before any such 60th day, to deliver such Officers'
Certificate and Securities specified in this paragraph, if any, shall not
constitute a default but shall constitute, on and as of such date, the
irrevocable election of the Issuer (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 Issuer 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 $50,000 (or the equivalent thereof in any Foreign Currency or ECU)
or a lesser sum in Dollars (or the equivalent thereof in any Foreign Currency
or ECU) if the Issuer 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





                                       82
   89
redemption price together with accrued interest to the date fixed for
redemption.  If such amount shall be $50,000 (or the equivalent thereof in any
Foreign Currency or ECU) or less and the Issuer makes no such request then it
shall be carried over until a sum in excess of $50,000 (or the equivalent
thereof in any Foreign Currency or ECU) is available.  The Trustee shall
select, in the manner provided in Section 11.2, for redemption on such sinking
fund payment date a sufficient principal amount of Securities of such series to
absorb said cash, as nearly as may be, and shall (if requested in writing by
the Issuer) inform the Issuer of the serial numbers of the Securities of such
series (or portions thereof) so selected.  Securities shall be excluded from
eligibility for redemption under this Section if they are identified by
registration and certificate number in an Officers' Certificate delivered to
the Trustee at least 60 days prior to the sinking fund payment date as being
owned of record and beneficially by, and not pledged or hypothecated by either
(a) the Issuer or (b) an entity specifically identified in such Officers'
Certificate as directly or indirectly controlling or controlled by or under
direct or indirect common control with the Issuer.  The Trustee, in the name
and at the expense of the Issuer (or the Issuer, if it shall so request the
Trustee in writing) shall cause notice of redemption of the Securities of such
series to be given in substantially the manner provided in Section 11.2 (and
with the effect provided in Section 11.3) for the redemption of Securities of
such series in part at the option of the Issuer.  The amount of any sinking
fund payments not so applied or allocated to the redemption of Securities of
such series shall be added to the next cash sinking fund payment for such
series and, together with such payment, shall be applied in accordance with the
provisions of this Section.  Any and all sinking fund moneys held on the stated
maturity date of the Securities of any particular series (or earlier, if such
maturity is accelerated), which are not held for the payment or redemption of
particular Securities of such series shall be applied, together with other
moneys, if necessary, sufficient for the purpose, to the payment of the
principal of, and interest on, the Securities of such series at maturity.

                 On or before each sinking fund payment date, the Issuer shall
pay to the Trustee in cash or shall otherwise provide for the payment of all
interest accrued to the date fixed for redemption on Securities to be redeemed
on such sinking fund payment date.

                 The Trustee shall not redeem or cause to be redeemed any
Securities of a series with sinking fund moneys or give any notice of
redemption of Securities for such series by operation of the sinking fund
during the continuance of a default in payment of interest on such Securities
or of any Event of Default





                                       83
   90
except that, where the giving of notice of redemption of any Securities shall
theretofore have been made, the Trustee shall redeem or cause to be redeemed
such Securities, provided that it shall have received from the Issuer a sum
sufficient for such redemption.  Except as aforesaid, any moneys in the sinking
fund for such series at the time when any such default or Event of Default
shall occur, and any moneys thereafter paid into the sinking fund, shall,
during the continuance of such default or Event of Default, be deemed to have
been collected under Article Four and held for the payment of all such
Securities.  In case such Event of Default shall have been waived as provided
in Section 4.10 or the default cured on or before the sixtieth day preceding
the sinking fund payment date in any year, such moneys shall thereafter be
applied on the next succeeding sinking fund payment date in accordance with
this Section to the redemption of such Securities.
