pledged in good faith may be regarded as Outstanding if the pledgee establishes
to the satisfaction of the Trustee (A) the pledgee's right so to act with
respect to such Securities and (B) that the pledgee is not the Company or any
other obligor upon the Securities or any Coupons appertaining thereto or an

Depository that is a Holder of a global Security may provide its proxy or
proxies to the beneficial owners of interests in any such global Security

determining the Persons who are beneficial owners of interest in any permanent
global Security held by a U.S. Depository entitled under the procedures of such

their duly appointed proxy or proxies, and only such Persons, shall be entitled
to make, give or take such request, demand, authorization, direction, notice,
consent, waiver or other Act, whether or not such Holders remain Holders after
such record date. No such request, demand, authorization, direction, notice,
consent, waiver or other Act shall be valid or effective if made, given or taken
more than 90 days after such record date.

                  (2) The fact and date of the execution by any Person of any
such instrument or writing may be proved in any reasonable manner which the
Trustee deems sufficient and in accordance with such reasonable rules as the
Trustee may determine; and the Trustee may in any instance require further proof
with respect to any of the matters referred to in this Section.

Registered Securities held by any Person, and the date of the commencement and
the date of the termination of holding the same, shall be proved by the Security
Register.

                  (4) The ownership, principal amount and serial numbers of
Bearer Securities held by any Person, and the date of the commencement and the
date of the termination of holding the same, may be proved by the production of
such Bearer Securities or by a certificate executed, as depositary, by any trust
company, bank, banker or other depositary reasonably acceptable to the Company,
wherever situated, if such certificate shall be deemed by the Company and the
Trustee to be satisfactory, showing that at the date therein mentioned such
Person had on deposit with such depositary, or exhibited to it, the Bearer
Securities therein described; or such facts may be proved by the certificate or
affidavit of the Person holding such Bearer Securities, if such certificate or
affidavit is deemed by the Trustee to be satisfactory. The Trustee and the
Company may assume that such ownership of any Bearer Security continues until
(1) another certificate or affidavit bearing a later date issued in respect of
the same Bearer Security is produced, or (2) such Bearer Security is produced to
the Trustee by some other Person, or (3) such Bearer Security is surrendered in
exchange for a Registered Security, or (4) such Bearer Security is no longer
Outstanding. The ownership, principal amount and serial numbers of Bearer
Securities held by the Person so executing such instrument or writing and the
date of the commencement and the date of the termination of holding the same may
also be proved in any other manner which the Company and the Trustee deem
sufficient.

                  (5) If the Company shall solicit from the Holders of any
Registered Securities any request, demand, authorization, direction, notice,
consent, waiver or other Act, the Company may at its option (but is not
obligated to), by Board Resolution, fix in advance a record date for the
determination of Holders of Registered Securities entitled to give such request,
demand, authorization, direction, notice, consent, waiver or other Act. If such
a record date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other Act may be given before or after such record date, but
only the Holders of Registered Securities of record at the close of business on
such record date shall be deemed to be Holders for the purpose of determining
whether Holders of the requisite proportion of Outstanding Securities have
authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other Act, and for that purpose the
Outstanding Securities shall be computed as of such record date; provided that
no such authorization, agreement or consent by the Holders

                                       13
<PAGE>

of Registered Securities shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than six months
after the record date.

                  (6) Any request, demand, authorization, direction, notice,
consent, waiver or other Act by the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done or suffered to be done by the Trustee, any Security
Registrar, any Paying Agent or the Company in reliance thereon, whether or not
notation of such Act is made upon such Security.

         expressly provided) if in writing and mailed, first-class postage
         prepaid, to the Company addressed to the attention of its Treasurer at

                  Section 116. Judgment Currency.

                  The Company 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 premium or interest, if any, or Additional Amounts on the
Securities of any series (the "Required Currency") into a currency in which a
judgment will be rendered (the "Judgment Currency"), the rate of exchange used
shall be the rate at which in accordance with normal banking procedures the
Trustee could purchase in The City of New York the Required Currency with the
Judgment Currency on the New York Banking Day preceding that on which a final
unappealable judgment is given and (b) the Company's 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 clause (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 obligated by law, regulation or executive
order to be closed.

in writing but need not be accompanied by or contained in an Officers'
Certificate and need not be accompanied by an Opinion of Counsel.

otherwise specified in or pursuant to this Indenture or any Securities, payment
of principal of, any premium and interest on, and any Additional Amounts in
respect of, any Security in temporary or permanent global form shall be made to

Securities shall authenticate and deliver such Securities. In authenticating
such Securities, and accepting the additional responsibilities under this
Indenture in relation to such Securities and any Coupons appertaining thereto,
the Trustee shall be entitled to receive, and (subject to Sections 315(a)
through 315(d) of the Trust Indenture Act) shall be fully protected in relying
upon,

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

                  (a) the form or forms and terms of such Securities and
         Coupons, if any, have been established in conformity with the
         provisions of this Indenture;

                  (b) all conditions precedent to the authentication and
         delivery of such Securities and Coupons, if any, appertaining thereto,
         have been complied with and that such Securities, and Coupons, when
         completed by appropriate insertions, executed under the Company's
         corporate seal and attested by duly authorized officers of the Company,
         delivered by duly authorized officers of the Company to the Trustee for
         authentication pursuant to this Indenture, and authenticated and
         delivered by the Trustee and issued by the Company in the manner and
         subject to any conditions specified in such Opinion of Counsel, will
         constitute legally valid and binding obligations of the Company,
         enforceable against the Company in accordance with their terms, except
         as enforcement thereof may be subject to or limited by bankruptcy,
         insolvency, reorganization, moratorium, arrangement, fraudulent
         conveyance, fraudulent transfer or other similar laws relating to or
         affecting creditors' rights generally, and subject to general
         principles of equity (regardless of whether enforcement is sought in a
         proceeding in equity or at

                                       23

         law) and will entitle the Holders thereof to the benefits of this
         Indenture; such Opinion of Counsel need express no opinion as to the
         availability of equitable remedies;

                  (c) all laws and requirements in respect of the execution and
         delivery by the Company of such Securities and Coupons, if any, have
         been complied with; and

                  (d) this Indenture has been qualified under the Trust
         Indenture Act; and

                  (2) an Officers' Certificate stating that, to the best
knowledge of the Persons executing such certificate, no event which is, or after
notice or lapse of time would become, an Event of Default with respect to any of
the Securities shall have occurred and be continuing.

                  If all the Securities of any series are not to be issued at
one time, it shall not be necessary to deliver an Opinion of Counsel and an
Officers' Certificate at the time of issuance of each Security, but such opinion
and certificate, with appropriate modifications, shall be delivered at or before
the time of issuance of the first Security of such series. After any such first
delivery, any separate request by the Company that the Trustee authenticate
Securities of such series for original issue will be deemed to be a
certification by the Company that all conditions precedent provided for in this
Indenture relating to authentication and delivery of such Securities continue to
have been complied with.

                  The Trustee shall not be required to authenticate or to cause
an Authenticating Agent to authenticate any Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee's own rights,
duties or immunities under the Securities and this Indenture or otherwise in a
manner which is not reasonably acceptable to the Trustee or if the Trustee,
being advised by counsel, determines that such action may not lawfully be taken.

                  Each Registered Security shall be dated the date of its
authentication. Each Bearer Security and any Bearer Security in global form
shall be dated as of the date specified in or pursuant to this Indenture.

                  No Security or Coupon appertaining thereto shall be entitled
to any benefit under this Indenture or be valid or obligatory for any purpose,
unless there appears on such Security a certificate of authentication
substantially in the form provided for in Section 202 or 611 executed by or on
behalf of the Trustee or by the Authenticating Agent by the manual signature of
one of its authorized officers. Such certificate upon any Security shall be
conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered hereunder. Except as permitted by Section 306 or
307, the Trustee shall not authenticate and deliver any Bearer Security unless
all Coupons appertaining thereto then matured have been detached and cancelled.

                  Section 304. Temporary Securities.

                  Pending the preparation of definitive Securities, the Company
may execute and deliver to the Trustee and, upon Company Order, the Trustee
shall authenticate and deliver, in the manner provided in Section 303, temporary
Securities in lieu thereof which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized

                                       24
<PAGE>

denomination, substantially of the tenor of the definitive Securities in lieu of
which they are issued, in registered form or, if authorized in or pursuant to
this Indenture, in bearer form with one or more Coupons or without Coupons and
with such appropriate insertions, omissions, substitutions and other variations
as the officers of the Company executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. Such temporary
Securities may be in global form.

                  Except in the case of temporary Securities in global form,
which shall be exchanged in accordance with the provisions thereof, if temporary
Securities are issued, the Company shall cause definitive Securities to be
prepared without unreasonable delay. After the preparation of definitive
Securities of the same series and containing terms and provisions that are
identical to those of any temporary Securities, such temporary Securities shall
be exchangeable for such definitive Securities upon surrender of such temporary
Securities at an Office or Agency for such Securities, without charge to any
Holder thereof. Upon surrender for cancellation of any one or more temporary
Securities (accompanied by any unmatured Coupons appertaining thereto), the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Securities of authorized
denominations of the same series and containing identical terms and provisions;
provided, however, that no definitive Bearer Security, except as provided in or
pursuant to this Indenture, shall be delivered in exchange for a temporary
Registered Security; and provided, further, that a definitive Bearer Security
shall be delivered in exchange for a temporary Bearer Security only in
compliance with the conditions set forth in or pursuant to this Indenture.
Unless otherwise provided in or pursuant to this Indenture with respect to a
temporary global Security, until so exchanged the temporary Securities of any
series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of such series.

                  Section 305. Registration, Transfer and Exchange.

                  With respect to the Registered Securities of each series, if
any, the Company shall cause to be kept a register (each such register being
herein sometimes referred to as the "Security Register") at an Office or Agency
for such series in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such
series. Such Office or Agency shall be the "Security Registrar" for that series
of Securities. Unless otherwise specified in or pursuant to this Indenture or
the Securities, the Trustee shall be the initial Security Registrar for each
series of Securities. The Company shall have the right to remove and replace
from time to time the Security Registrar for any series of Securities; provided
that no such removal or replacement shall be effective until a successor
Security Registrar with respect to such series of Securities shall have been
appointed by the Company and shall have accepted such appointment by the
Company. In the event that the Trustee shall not be or shall cease to be
Security Registrar with respect to a series of Securities, it shall have the
right to examine the Security Register for such series at all reasonable times.
There shall be only one Security Register for each series of Securities.

                                       25
<PAGE>

                  Upon surrender for registration of transfer of any Registered
Security of any series at any Office or Agency for such series, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Registered Securities
of the same series denominated as authorized in or pursuant to this Indenture,
of a like aggregate principal amount bearing a number not contemporaneously
outstanding and containing identical terms and provisions.

                  At the option of the Holder, Registered Securities of any
series may be exchanged for other Registered Securities of the same series
containing identical terms and provisions, in any authorized denominations, and
of a like aggregate principal amount, upon surrender of the Securities to be
exchanged at any Office or Agency for such series. Whenever any Registered
Securities are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Registered Securities which the
Holder making the exchange is entitled to receive.

                  If provided in or pursuant to this Indenture, with respect to
Securities of any series, at the option of the Holder, Bearer Securities of such
series may be exchanged for Registered Securities of such series containing
identical terms, denominated as authorized in or pursuant to this Indenture and
in the same aggregate principal amount, upon surrender of the Bearer Securities
to be exchanged at any Office or Agency for such series, with all unmatured
Coupons and all matured Coupons in default thereto appertaining. If the Holder
of a Bearer Security is unable to produce any such unmatured Coupon or Coupons
or matured Coupon or Coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company
and the Trustee in an amount equal to the face amount of such missing Coupon or
Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that, except as otherwise provided in Section 1002, interest
represented by Coupons shall be payable only upon presentation and surrender of
those Coupons at an Office or Agency for such series located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such Office or Agency for such series in exchange for a
Registered Security of such series and like tenor after the close of business at
such Office or Agency on (i) any Regular Record Date and before the opening of
business at such Office or Agency on the relevant Interest Payment Date, or (ii)
any Special Record Date and before the opening of business at such Office or
Agency on the related date for payment of Defaulted Interest, such Bearer
Security shall be surrendered without the Coupon relating to such Interest
Payment Date or proposed date of payment, as the case may be (or, if such Coupon
is so surrendered with such Bearer Security, such Coupon shall be returned to
the Person so surrendering the Bearer Security), and interest or Defaulted
Interest, as the case may be, shall not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but shall be payable only
to the Holder of such Coupon when due in accordance with the provisions of this
Indenture.

                                       26
<PAGE>

                  If provided in or pursuant to this Indenture with respect to
Securities of any series, at the option of the Holder, Registered Securities of
such series may be exchanged for Bearer Securities upon such terms and
conditions as may be provided in or pursuant to this Indenture with respect to
such series.

                  Whenever any Securities are surrendered for exchange as
contemplated by the immediately preceding two paragraphs, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.

                  Notwithstanding the foregoing, except as otherwise provided in
or pursuant to this Indenture, any global Security shall be exchangeable for
definitive Securities only if (i) the Depository is at any time unwilling,
unable or ineligible to continue as Depository and a successor depository is not
appointed by the Company within 90 days of the date the Company is so informed
in writing, (ii) the Company executes and delivers to the Trustee a Company
Order to the effect that such global Security shall be so exchangeable, or (iii)
an Event of Default has occurred and is continuing with respect to the
Securities. If the beneficial owners of interests in a global Security are
entitled to exchange such interests for definitive Securities as the result of
an event described in clause (i), (ii) or (iii) of the preceding sentence, then
without unnecessary delay but in any event not later than the earliest date on
which such interests may be so exchanged, the Company shall deliver to the
Trustee definitive Securities in such form and denominations as are required by
or pursuant to this Indenture, and of the same series, containing identical
terms and in aggregate principal amount equal to the principal amount of such
global Security, executed by the Company. On or after the earliest date on which
such interests may be so exchanged, such global Security shall be surrendered
from time to time by the U.S. Depository or such other Depository as shall be
specified in the Company Order with respect thereto, and in accordance with
instructions given to the Trustee and the U.S. Depository or such other
Depository, as the case may be (which instructions shall be in writing but need
not be contained in or accompanied by an Officers' Certificate or be accompanied
by an Opinion of Counsel), as shall be specified in the Company Order with
respect thereto to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or in part, for definitive Securities as described above
without charge. The Trustee shall authenticate and make available for delivery,
in exchange for each portion of such surrendered global Security, a like
aggregate principal amount of definitive Securities of the same series of
authorized denominations and of like tenor as the portion of such global
Security to be exchanged, which (unless such Securities are not issuable both as
Bearer Securities and as Registered Securities, in which case the definitive
Securities exchanged for the global Security shall be issuable only in the form
in which the Securities are issuable, as provided in or pursuant to this
Indenture) shall be in the form of Bearer Securities or Registered Securities,
or any combination thereof, as shall be specified by the beneficial owner
thereof, but subject to the satisfaction of any certification or other
requirements to the issuance of Bearer Securities; provided, however, that no
such exchanges may occur during a period beginning at the opening of business 15
days before any selection of Securities of the same series to be redeemed and
ending on the relevant Redemption Date; and provided, further, that (unless
otherwise provided in or pursuant to this Indenture) no Bearer Security
delivered in exchange for a portion of a global Security shall be mailed or
otherwise delivered to any location in the United States. Promptly following any
such exchange

                                       27
<PAGE>

in part, such global Security shall be returned by the Trustee to such
Depository or the U.S. Depository, as the case may be, or such other Depository
or U.S. Depository referred to above in accordance with the instructions of the
Company referred to above. If a Registered Security is issued in exchange for
any portion of a global Security after the close of business at the Office or
Agency for such Security where such exchange occurs on or after (i) any Regular
Record Date for such Security and before the opening of business at such Office
or Agency on the next Interest Payment Date, or (ii) any Special Record Date for
such Security and before the opening of business at such Office or Agency on the
related proposed date for payment of interest or Defaulted Interest, as the case
may be, interest shall not be payable on such Interest Payment Date or proposed
date for payment, as the case may be, in respect of such Registered Security,
but shall be payable on such Interest Payment Date or proposed date for payment,
as the case may be, only to the Person to whom interest in respect of such
portion of such global Security shall be payable in accordance with the
provisions of this Indenture.

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

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

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

                  Except as otherwise provided in or pursuant to this Indenture,
the Company shall not be required (i) to issue, register the transfer of or
exchange any Securities during a period beginning at the opening of business 15
days before the day of the selection for redemption of Securities of like tenor
and the same series under Section 1103 and ending at the close of business on
the day of such selection, or (ii) to register the transfer of or exchange any
Registered Security so selected for redemption in whole or in part, except in
the case of any Security to be redeemed in part, the portion thereof not to be
redeemed, or (iii) to exchange any Bearer Security so selected for redemption
except, to the extent provided with respect to such Bearer Security, that such
Bearer Security may be exchanged for a Registered Security of like tenor and the
same series, provided that such Registered Security shall be immediately
surrendered for redemption with written instruction for payment consistent with
the provisions of this Indenture or (iv) to issue, register the transfer of or
exchange any Security which, in accordance with its terms, has been surrendered
for repayment at the option of the Holder, except the portion, if any, of such
Security not to be so repaid.

                  Section 306. Mutilated, Destroyed, Lost and Stolen Securities.

                  If any mutilated Security or a Security with a mutilated
Coupon appertaining to it is surrendered to the Trustee, subject to the
provisions of this Section 306, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a new Security of the same series
containing identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

                  If there be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or Coupon, and (ii) such security or indemnity as may be required by them to
save each of them and any agent of either of them harmless, then, in the absence
of notice to the Company or the Trustee that such Security or Coupon has been
acquired by a bona fide purchaser, the Company shall execute and, upon Company
Request the Trustee shall authenticate and deliver, in exchange for or in lieu
of any such mutilated, destroyed, lost or stolen Security or in exchange for the
Security to which a destroyed, lost or stolen Coupon appertains with all
appurtenant Coupons not destroyed, lost or stolen, a new Security of the same
series containing identical terms and of like principal amount and bearing a
number not contemporaneously outstanding, with Coupons corresponding to the
Coupons, if any, appertaining to such destroyed, lost or stolen Security or to
the Security to which such destroyed, lost or stolen Coupon appertains.

                  Notwithstanding the foregoing provisions of this Section 306,
in case any mutilated, destroyed, lost or stolen Security or Coupon has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security or Coupon; provided,
however, that principal of, any premium or interest on or any Additional Amounts
with respect to any Bearer Securities shall, except as otherwise provided in
Section 1002, be payable only at an Office or Agency for such Securities located
outside the United States and, unless otherwise provided in or pursuant to this
Indenture, any interest on Bearer Securities and any Additional Amounts with
respect to such interest shall be payable only upon presentation and surrender
of the Coupons appertaining thereto.

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

                  Every new Security, with any Coupons appertaining thereto
issued pursuant to this Section in lieu of any destroyed, lost or stolen
Security, or in exchange for a Security to which a destroyed, lost or stolen
Coupon appertains shall constitute a separate obligation of the Company, whether
or not the destroyed, lost or stolen Security and Coupons appertaining thereto
or the destroyed, lost or stolen Coupon shall be at any time enforceable by
anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of such series and the
Coupons, if any, duly issued hereunder.

<PAGE>

                  The provisions of this Section, as amended or supplemented
pursuant to this Indenture with respect to particular Securities or generally,
shall be exclusive and shall preclude (to the extent lawful) all other rights
and remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities or Coupons.

                  Section 307.  Payment of Interest and Certain Additional
                                Amounts; Rights to Interest and Certain
                                Additional Amounts Preserved.

                  Unless otherwise provided in or pursuant to this Indenture,
any interest on and any Additional Amounts with respect to any Registered
Security which shall be payable, and are punctually paid or duly provided for,
on any Interest Payment Date shall be paid to the Person in whose name such
Security (or one or more Predecessor Securities) is registered as of the close
of business on the Regular Record Date for such interest. Unless otherwise
provided in or pursuant to this Indenture, in case a Bearer Security is
surrendered in exchange for a Registered Security after the close of business at
an Office or Agency for such Security on any Regular Record Date therefor and
before the opening of business at such Office or Agency on the next succeeding
Interest Payment Date therefor, such Bearer Security shall be surrendered
without the Coupon relating to such Interest Payment Date and interest shall not
be payable on such Interest Payment Date in respect of the Registered Security
issued in exchange for such Bearer Security, but shall be payable only to the
Holder of such Coupon when due in accordance with the provisions of this
Indenture.

                  Unless otherwise provided in or pursuant to this Indenture,
any interest on and any Additional Amounts with respect to any Registered
Security which shall be payable, but shall not be punctually paid or duly
provided for, on any Interest Payment Date for such Registered Security (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
thereof on the relevant Regular Record Date by virtue of having been such
Holder; and such Defaulted Interest may be paid by the Company, at its election
in each case, as provided in Clause (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
         Interest to the Person in whose name such Registered Security (or a
         Predecessor Security thereof) shall be registered at the close of
         business on a Special Record Date for the payment of such Defaulted
         Interest, which shall be fixed in the following manner. The Company
         shall notify the Trustee in writing of the amount of Defaulted Interest
         proposed to be paid on such Registered Security and the date of the
         proposed payment, and at the same time the Company shall deposit with
         the Trustee an amount of money equal to the aggregate amount proposed
         to be paid in respect of such Defaulted Interest or shall make
         arrangements satisfactory to the Trustee for such deposit on or prior
         to the date of the proposed payment, such money when so deposited to be
         held in trust for the benefit of the Person entitled to such Defaulted
         Interest as in this Clause provided. Thereupon, the Trustee shall fix a
         Special Record Date for the payment of such Defaulted Interest which
         shall be not more than 15 days and not less than 10 days prior to the
         date of the proposed payment and not less than 10 days after the
         receipt by the Trustee of the notice of the proposed payment. The
         Trustee shall promptly notify the Company of such Special Record Date
         and, in the name and at the expense of the Company shall cause notice
         of the proposed payment of such Defaulted Interest and the Special

                                       30
<PAGE>

         Record Date therefor to be mailed, first-class postage prepaid, to the
         Holder of such Registered Security (or a Predecessor Security thereof)
         at his address as it appears in the Security Register not less than 10
         days prior to such Special Record Date. The Trustee may, in its
         discretion, in the name and at the expense of the Company cause a
         similar notice to be published at least once in an Authorized Newspaper
         of general circulation in the Borough of Manhattan, The City of New
         York, but such publication shall not be a condition precedent to the
         establishment of such Special Record Date. Notice of the proposed
         payment of such Defaulted Interest and the Special Record Date therefor
         having been mailed as aforesaid, such Defaulted Interest shall be paid
         to the Person in whose name such Registered Security (or a Predecessor
         Security thereof) shall be registered at the close of business on such
         Special Record Date and shall no longer be payable pursuant to the
         following clause (2). In case a Bearer Security is surrendered at the
         Office or Agency for such Security in exchange for a Registered
         Security after the close of business at such Office or Agency on any
         Special Record Date and before the opening of business at such Office
         or Agency on the related proposed date for payment of Defaulted
         Interest, such Bearer Security shall be surrendered without the Coupon
         relating to such Defaulted Interest and Defaulted Interest shall not be
         payable on such proposed date of payment in respect of the Registered
         Security issued in exchange for such Bearer Security, but shall be
         payable only to the Holder of such Coupon when due in accordance with
         the provisions of this Indenture.

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

                  Unless otherwise provided in or pursuant to this Indenture or
the Securities of any particular series, at the option of the Company, interest
on Registered Securities that bear interest may be paid by mailing a check to
the address of the Person entitled thereto as such address shall appear in the
Security Register or by transfer to an account maintained by the payee with a
bank located in the United States.

                  Subject to the foregoing provisions of this Section and
Section 305, each Security delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Security shall carry the
rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

                  Section 308. Persons Deemed Owners.

                  Prior to due presentment of a Registered Security for
registration of transfer, the Company, the Trustee and any agent of the Company

                     SATISFACTION AND DISCHARGE OF INDENTURE

                  Section 401. Satisfaction and Discharge.

                  Upon the direction of the Company by a Company Order, this
Indenture shall cease to be of further effect with respect to any series of
Securities specified in such Company Order and any Coupons appertaining thereto,
and the Trustee, on receipt of a Company Order, at the expense of the Company,
shall execute proper instruments acknowledging satisfaction and discharge of
this Indenture as to such series, when

                  (1) either

                           (a) all Securities of such series theretofore
         authenticated and delivered and all Coupons appertaining thereto (other
         than (i) Coupons appertaining to Bearer Securities of such series
         surrendered in exchange for Registered Securities of such series and
         maturing after such exchange whose surrender is not required or has
         been waived as provided in Section 305, (ii) Securities and Coupons of
         such series which have been destroyed, lost or stolen and which have
         been replaced or paid as provided in Section 306, (iii) Coupons

         such series for whose payment money in the applicable Currency has
         theretofore been deposited in trust or segregated and held in trust by

         such trust, as provided in Section 1003) have been delivered to the
         Trustee for cancellation; or

                           (b) all Securities of such series and, in the case of
         (i) or (ii) below, any Coupons appertaining thereto not theretofore
         delivered to the Trustee for cancellation

                                    (i) have become due and payable, or

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

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

         and the Company, in the case of (i), (ii) or (iii) above, has deposited
         or caused to be deposited with the Trustee as trust funds in trust for
         such purpose, money in the Currency in which such Securities are
         payable in an amount sufficient to pay and discharge the entire
         indebtedness on such Securities and any Coupons appertaining thereto
         not theretofore delivered to the Trustee for cancellation, including
         the principal of, any premium and interest on, and any Additional
         Amounts with respect to such Securities and

                                       33
<PAGE>

         any Coupons appertaining thereto, to the date of such deposit (in the
         case of Securities which have become due and payable) or to the
         Maturity thereof, as the case may be;

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

                  (3) the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent herein provided for relating to the satisfaction and
         discharge of this Indenture as to such series have been complied with.

                  In the event there are Securities of two or more series
hereunder, the Trustee shall be required to execute an instrument acknowledging
satisfaction and discharge of this Indenture only if requested to do so with
respect to Securities of such series as to which it is Trustee and if the other
conditions thereto are met.

                  Notwithstanding the satisfaction and discharge of this
Indenture with respect to any series of Securities, the obligations of the
Company to the Trustee under Section 606 and, if money shall have been deposited
with the Trustee pursuant to subclause (b) of clause (1) of this Section, the
obligations of the Company and the Trustee with respect to the Securities of
such series under Sections 305, 306, 403, 1002 and 1003, with respect to the
payment of Additional Amounts, if any, with respect to such Securities as
contemplated by Section 1004 (but only to the extent that the Additional Amounts
payable with respect to such Securities exceed the amount deposited in respect
of such Additional Amounts pursuant to Section 401(1)(b)), shall survive.

                  Section 402. Defeasance and Covenant Defeasance.

                  (1) Unless, pursuant to Section 301, either or both of (i)
defeasance of the Securities of or within a series under clause (2) of this
Section 402, or (ii) covenant defeasance of the Securities of or within a series
under clause (3) of this Section 402 shall not be applicable with respect to the
Securities of such series, then such provisions, together with the other
provisions of this Section 402 (with such modifications thereto as may be
specified pursuant to Section 301 with respect to any Securities), shall be
applicable to such Securities and any Coupons appertaining thereto, and the
Company may at its option by Board Resolution or Officers' Certificate, at any
time, with respect to such Securities and any Coupons appertaining thereto,
elect to have Section 402(2) or Section 402(3) be applied to such Outstanding
Securities and any Coupons appertaining thereto upon compliance with the
conditions set forth below in this Section 402.

                  (2) Upon the Company's exercise of the above option applicable
to this Section 402(2) with respect to any Securities of or within a series, the
Company shall be deemed to have been discharged from its obligations with
respect to such Outstanding Securities and any Coupons appertaining thereto on
the date the conditions set forth in clause (4) of this Section 402 are
satisfied (hereinafter, "defeasance"). For this purpose, such defeasance means
that the Company shall be deemed to have paid and discharged the entire
Indebtedness represented by

                                       34
<PAGE>

such Outstanding Securities and any Coupons appertaining thereto, which shall
thereafter be deemed to be "Outstanding" only for the purposes of clause (5) of
this Section 402 and the other Sections of this Indenture referred to in clauses
(i) and (ii) below, and to have satisfied all of its other obligations under
such Securities and any Coupons appertaining thereto and this Indenture insofar
as such Securities and any Coupons appertaining thereto are concerned (and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following which shall survive until
otherwise terminated or discharged hereunder: (i) the rights of Holders of such
Outstanding Securities and any Coupons appertaining thereto to receive, solely
from the trust fund described in clause (4) of this Section 402 and as more
fully set forth in such Section, payments in respect of the principal of (and
premium, if any) and interest, if any, on, and Additional Amounts, if any, with
respect to, such Securities and any Coupons appertaining thereto when such
payments are due, and any rights of such Holder to convert or exchange such
Securities into Common Stock or other securities, (ii) the obligations of the
Company and the Trustee with respect to such Securities under Sections 305, 306,
1002 and 1003, with respect to the payment of Additional Amounts, if any, on
such Securities as contemplated by Section 1004 (but only to the extent that the
Additional Amounts payable with respect to such Securities exceed the amount
deposited in respect of such Additional Amounts pursuant to Section 401(4)(a)
below), (iii) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (iv) this Section 402. The Company may exercise its option under
this Section 402(2) notwithstanding the prior exercise of its option under
clause (3) of this Section 402 with respect to such Securities and any Coupons
appertaining thereto.

                  (3) Upon the Company's exercise of the above option applicable
to this Section 402(3) with respect to any Securities of or within a series, the
Company shall be released from its obligations under Sections 1005 and 1006,
and, to the extent specified pursuant to Section 301, any other covenant
applicable to such Securities, with respect to such Outstanding Securities and
any Coupons appertaining thereto on and after the date the conditions set forth
in clause (4) of this Section 402 are satisfied (hereinafter, "covenant
defeasance"), and such Securities and any Coupons appertaining thereto shall
thereafter be deemed to be not "Outstanding" for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with any such covenant, but shall continue to be deemed
"Outstanding" for all other purposes hereunder. For this purpose, such covenant
defeasance means that, with respect to such Outstanding Securities and any
Coupons appertaining thereto, the Company may omit to comply with, and shall
have no liability in respect of, any term, condition or limitation set forth in
any such Section or such other covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any such Section or such other
covenant or by reason of reference in any such Section or such other covenant to
any other provision herein or in any other document and such omission to comply
shall not constitute a default or an Event of Default under Section 501(3) or
501(4) or otherwise, as the case may be, but, except as specified above, the
remainder of this Indenture and such Securities and Coupons appertaining thereto
shall be unaffected thereby.

                  (4) The following shall be the conditions to application of
clause (2) or (3) of this Section 402 to any Outstanding Securities of or within
a series and any Coupons appertaining thereto:

                                       35
<PAGE>

                  (a) The Company shall irrevocably have deposited or caused to
         be deposited with the Trustee (or another trustee satisfying the
         requirements of Section 607 who shall agree to comply with the
         provisions of this Section 402 applicable to it) 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 such Securities and any Coupons appertaining thereto,

                           (1) an amount in Dollars or in such Foreign Currency
                  in which such Securities and any Coupons appertaining thereto
                  are then specified as payable at Stated Maturity, or

                           (2) Government Obligations applicable to such
                  Securities and Coupons appertaining thereto (determined on the
                  basis of the Currency in which such Securities and Coupons
                  appertaining thereto are then specified as payable at Stated
                  Maturity) which through the scheduled payment of principal and
                  interest in respect thereof in accordance with their terms
                  will provide, not later than one day before the due date of
                  any payment of principal of (and premium, if any) and
                  interest, if any, on such Securities and any Coupons
                  appertaining thereto, money in an amount, or

                           (3) a combination thereof,

                  in any case, in an amount, sufficient, without consideration
                  of any reinvestment of such principal and interest, in the
                  opinion of a nationally recognized firm of independent public
                  accountants expressed in a written certification thereof
                  delivered to the Trustee, to pay and discharge, and which
                  shall be applied by the Trustee (or other qualifying trustee)
                  to pay and discharge, the principal of (and premium, if any)
                  and interest, if any, on such Outstanding Securities and any
                  Coupons appertaining thereto on the Stated Maturity of such
                  principal or installment of principal or interest on the day
                  on which such payments are due and payable in accordance with
                  the terms of this Indenture and of such Securities and any
                  Coupons appertaining thereto.

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

                  (c) No Event of Default or event which with notice or lapse of
         time or both would become an Event of Default with respect to such
         Securities and any Coupons appertaining thereto shall have occurred and
         be continuing on the date of such deposit and, with respect to
         defeasance only, 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).

                  (d) In the case of an election under clause (2) of this
         Section 402, the Company shall have delivered to the Trustee an Opinion
         of Counsel stating that (i) the

                                       36
<PAGE>

         Company has received from the Internal Revenue Service a letter ruling,
         or there has been published by the Internal Revenue Service a Revenue
         Ruling, or (ii) since the date of execution of this Indenture, there
         has been a change in the applicable Federal income tax law, in either
         case to the effect that, and based thereon such opinion shall confirm
         that, the Holders of such Outstanding Securities and any Coupons
         appertaining thereto will not recognize income, gain or loss for
         Federal income tax purposes as a result of such 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 defeasance
         had not occurred.

                  (e) In the case of an election under clause (3) of this
         Section 402, the Company shall have delivered to the Trustee an Opinion
         of Counsel to the effect that the Holders of such Outstanding
         Securities and any 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.

                  (f) The Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that all
         conditions precedent to the defeasance or covenant defeasance under
         clause (2) or (3) of this Section 402 (as the case may be) have been
         complied with.

                  (g) Notwithstanding any other provisions of this Section
         402(4), such defeasance or covenant defeasance shall be effected in
         compliance with any additional or substitute terms, conditions or
         limitations which may be imposed on the Company in connection therewith
         pursuant to Section 301.

                  (5) Subject to the provisions of the last paragraph of Section
1003, all money and Government Obligations (or other property as may be provided
pursuant to Section 301) (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee, collectively for purposes of this Section
402(5) and Section 403, the "Trustee") pursuant to clause (4) of Section 402 in
respect of any Outstanding Securities of any series and any Coupons appertaining
thereto shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and any Coupons appertaining thereto and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities and any Coupons appertaining
thereto of all sums due and to become due thereon in respect of principal (and
premium, if any) and interest and Additional Amounts, if any, but such money
need not be segregated from other funds except to the extent required by law.

                  Unless otherwise specified in or pursuant to this Indenture or
any Security, if, after a deposit referred to in Section 402(4)(a) has been
made, (a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 402(4)(a) has been made in respect of such Security, or (b)
a Conversion

                                       37
<PAGE>

Event occurs in respect of the Foreign Currency in which the deposit pursuant to
Section 402(4)(a) has been made, the indebtedness represented by such Security
and any Coupons appertaining thereto shall be deemed to have been, and will be,
fully discharged and satisfied through the payment of the principal of (and
premium, if any), and interest, if any, on, and Additional Amounts, if any, with
respect to, such Security as the same becomes due out of the proceeds yielded by
converting (from time to time as specified below in the case of any such
election) the amount or other property deposited in respect of such Security
into the Currency in which such Security becomes payable as a result of such
election or Conversion Event based on (x) in the case of payments made pursuant
to clause (a) above, the applicable market exchange rate for such Currency in
effect on the second Business Day prior to each payment date, or (y) with
respect to a Conversion Event, the applicable market exchange rate for such
Foreign Currency in effect (as nearly as feasible) at the time of the Conversion
Event.

                  The Company shall pay and indemnify the Trustee against any
tax, fee or other charge, imposed on or assessed against the Government
Obligations deposited pursuant to this Section 402 or the principal or interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of such Outstanding Securities and any
Coupons appertaining thereto.

                  Anything in this Section 402 to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or Government Obligations (or other property and any proceeds
therefrom) held by it as provided in clause (4) of this Section 402 which, in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect a defeasance or covenant defeasance, as applicable, in accordance with
this Section 402.

                  Section 403. Application of Trust Money.

                  Subject to the provisions of the last paragraph of Section
1003, all money and Government Obligations deposited with the Trustee pursuant
to Section 401 or 402 shall be held in trust and applied by it, in accordance
with the provisions of the Securities, the Coupons and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal, premium, interest and Additional Amounts for
whose payment such money has or Government Obligations have been deposited with
or received by the Trustee; but such money and Government Obligations need not
be segregated from other funds except to the extent required by law.

                  Section 404. Reinstatement.

                  If the Trustee or the Paying Agent is unable to apply any
money in accordance with this Article with respect to any Securities by reason
of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, then the obligations
under this Indenture and such Securities from which the Company has been

                                       38
<PAGE>

discharged or released pursuant to this Article shall be revived and reinstated
as though no deposit has occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to this Article with respect to such Securities
in accordance with this Article; provided, however, that if the Company makes
any payment of principal of or any premium or interest on any such Security
following reinstatement of its obligations, the Company shall be subrogated to
the rights (if any) of the Holders of such Securities to receive such payment
from the money so held in trust.

this Indenture with respect to Securities of such series.

                  Section 502. Acceleration of Maturity; Rescission and
Annulment.

                  If an Event of Default with respect to Securities of any
series at the time Outstanding (other than an Event of Default specified in
clause (6) or (7) of Section 501) occurs and is continuing, then the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding
Securities of such series may declare the principal of all the Securities of
such series, or such lesser amount as may be provided for in the Securities of
such series, to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by the Holders), and upon any such
declaration such principal or such lesser amount shall become immediately due
and payable.

                  If an Event of Default specified in clause (6) or (7) of
Section 501 occurs, all unpaid principal of and accrued interest on the
Outstanding Securities of that series (or such lesser amount as may be provided
for in the Securities of such series) shall ipso facto become and be immediately
due and payable without any declaration or other act on the part of the Trustee
or any Holder of any Security of that series.

                  At any time after Securities of any series have been
accelerated and before a judgment or decree for payment of the money due has
been obtained by the Trustee as hereinafter in this Article provided, the
Holders of not less than a majority in principal amount of the Outstanding
Securities of such series, by written notice to the Company and the Trustee, may
rescind and annul such declaration and its consequences if

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

                  (a) all overdue installments of any interest on and Additional
         Amounts with respect to all Securities of such series and any Coupon
         appertaining thereto,

                  (b) the principal of and any premium on any Securities of such
         series which have become due otherwise than by such declaration of
         acceleration and interest thereon and any Additional Amounts with
         respect thereto at the rate or rates borne by or provided for in such
         Securities,

                  (c) to the extent that payment of such interest or Additional
         Amounts is lawful, interest upon overdue installments of any interest
         and Additional Amounts at the rate or rates borne by or provided for in
         such Securities, and

                  (d) all sums paid or advanced by the Trustee hereunder and the
         reasonable compensation, expenses, disbursements and advances of the
         Trustee, its agents and counsel and all other amounts due the Trustee
         under Section 606; and

                  (2) all Events of Default with respect to Securities of such
series, other than the non-payment of the principal of, any premium and interest
on, and any Additional Amounts

                                       41
<PAGE>

with respect to Securities of such series which shall have become due solely by
such declaration of acceleration, shall have been cured or waived as provided in
Section 513.

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

                  Section 503. Collection of Indebtedness and Suits for
Enforcement by Trustee.

                  The Company covenants that if

                  (1) there is a failure to pay any installment of interest on
or any Additional Amounts with respect to any Security or any Coupon
appertaining thereto when such interest or Additional Amounts shall have become
due and payable and such default continues for a period of 30 days, or

                  (2) there is a failure to pay the principal of or any premium
on any Security at its Maturity,

the Company shall, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities and any Coupons appertaining thereto,
the whole amount of money then due and payable with respect to such Securities
and any Coupons appertaining thereto, with interest upon the overdue principal,
any premium and, to the extent that payment of such interest shall be legally
enforceable, upon any overdue installments of interest and Additional Amounts at
the rate or rates borne by or provided for in such Securities, and, in addition
thereto, such further amount of money as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel and all other
amounts due to the Trustee under Section 606.

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

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

                  Section 504. Trustee May File Proofs of Claim.

                  In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or such other obligor or their
creditors, 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 on
the Company for the payment of any overdue principal, premium, interest or
Additional Amounts) shall be entitled and empowered, by intervention in such
proceeding or otherwise,

                  (1) to file and prove a claim for the whole amount, or such
         lesser amount as may be provided for in the Securities of such series,
         of the principal and any premium, interest and Additional Amounts owing
         and unpaid in respect of the Securities and any Coupons appertaining
         thereto 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 the reasonable compensation, expenses, disbursements and
         advances of the Trustee, its agents or counsel) and of the Holders of
         Securities or any Coupons allowed in such judicial proceeding, and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder of Securities or any Coupons to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders of Securities or any Coupons, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel and any other amounts due the
Trustee under Section 606.

                  Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder of
a Security or any Coupon any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or Coupons or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any
Holder of a Security or any Coupon in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors'
committee or other similar committee.

                  Section 505. Trustee May Enforce Claims without Possession of
                               Securities or Coupons.

                  All rights of action and claims under this Indenture or any of
the Securities or Coupons may be prosecuted and enforced by the Trustee without
the possession of any of the Securities or Coupons or the production thereof in
any proceeding relating thereto, and any such proceeding instituted by the
Trustee shall be brought in its own name as trustee of an express

                                       43
<PAGE>

trust, and any recovery or judgment, after provision for the payment of the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, shall be for the ratable benefit of each and every
Holder of a Security or Coupon in respect of which such judgment has been
recovered.

                  Section 506. Application of Money Collected.

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

                  FIRST: To the payment of all amounts due the Trustee and any
         predecessor Trustee under Section 606;

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

                  THIRD: The balance, if any, to the Person or Persons entitled
         thereto.

                  Section 507. Limitations on Suits.

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

                  (1) such Holder has previously given written notice to the
                  Trustee of a continuing Event of Default with respect to the
                  Securities of such series;

                  (2) the Holders of not less than 25% in principal amount of
                  the Outstanding Securities of such series shall have made
                  written request to the Trustee to institute proceedings in
                  respect of such Event of Default in its own name as Trustee
                  hereunder;

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

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

                                       44
<PAGE>

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

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

                  Section 508. Unconditional Right of Holders to Receive
                               Principal and any Premium, Interest and
                               Additional Amounts.

                  Notwithstanding any other provision in this Indenture, the
Holder of any Security or Coupon shall have the right, which is absolute and
unconditional, to receive payment of the principal of, any premium and (subject
to Sections 305 and 307) interest on, and any Additional Amounts with respect to
such Security or payment of such Coupon, as the case may be, on the respective
Stated Maturity or Maturities therefor specified in such Security or Coupon (or,
in the case of redemption, on the Redemption Date or, in the case of repayment
at the option of such Holder if provided in or pursuant to this Indenture, on
the date such repayment is due, or in the case of a Change in Control, or as to
any Change in Control Purchase Notice given timely, on the Change in Control
Purchase Date) and to institute suit for the enforcement of any such payment,
and such right shall not be impaired without the consent of such Holder.

                  Section 509. Restoration of Rights and Remedies.

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

                  Section 510. Rights and Remedies Cumulative.

                  Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities or Coupons in the
last paragraph of Section 306, no right or remedy herein conferred upon or
reserved to the Trustee or to each and every Holder of a Security or a Coupon is
intended to be exclusive of any other right or remedy, and every right and
remedy, to the extent permitted by law, shall 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, to the

                                       45
<PAGE>

extent permitted by law, prevent the concurrent assertion or employment of any
other appropriate right or remedy.

                  Section 511. Delay or Omission Not Waiver.

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

                  Section 512. Control by Holders of Securities.

                  Subject to Section 601(5), the Holders of a majority in
principal amount of the Outstanding Securities of any series shall have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on
the Trustee with respect to the Securities of such series and any Coupons
appertaining thereto, provided that

                  (1) such direction shall not be in conflict with any rule of
                  law or with this Indenture or with the Securities of any
                  series,

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

                  (3) such direction is not unduly prejudicial to the rights of
                  the other Holders of Securities of such series not joining in
                  such action.

                  Section 513. Waiver of Past Defaults.

                  The Holders of not less than a majority in principal amount of
the Outstanding Securities of any series on behalf of the Holders of all the
Securities of such series and any Coupons appertaining thereto may waive any
past or prospective default hereunder with respect to such series and its
consequences, except a default

                  (1) in the payment of the principal of, any premium or
                  interest on, or any Additional Amounts with respect to, any
                  Security of such series or any Coupons appertaining thereto,
                  or

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

                                       46
<PAGE>

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

                  Section 514. Waiver of Stay or Extension Laws.

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

                  Section 515. Undertaking for Costs

                  All parties to this Indenture agree, and each Holder of any
Security by his acceptance thereof shall be deemed to have agreed, that any
court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Indenture, or in any suit against the Trustee for any
action taken or omitted by it as Trustee, the filing by any party litigant in
such suit of any 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 515 shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of Outstanding Securities of any
series, or to any suit instituted by any Holder for the enforcement of the
payment of the principal of (or premium, if any) or interest, if any, on or
Additional Amounts, if any, with respect to any Security on or after the
respective Stated Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date, in the case of repayment, on or
after the date for repayment and, in the case of Change of Control, on or after
the date for payment of the Change of Control Purchase Price).

the same rights it would have if it were not Trustee, Authenticating Agent,
Paying Agent, Security Registrar or such other Person.

                  Except as provided in Section 403 and Section 1003, money held

                  compensation for all services rendered by the Trustee

                  an express trust);

                  (2) except as otherwise expressly provided herein, to
                  reimburse the Trustee upon its request for all reasonable
                  expenses, disbursements and advances incurred or made by the
                  Trustee in accordance with any provision of this Indenture
                  (including the reasonable compensation and the expenses and
                  disbursements of its agents and counsel), except any such
                  expense, disbursement or advance as may be attributable to the
                  Trustee's negligence or bad faith; and

                  (3) to indemnify the Trustee and its agents for, and to hold
                  them harmless against, any loss, liability or expense incurred
                  without negligence or bad faith on their part, arising out of
                  or in connection with the acceptance or administration of the

                  powers or duties hereunder.

                  As security for the performance of the obligations of the

                  imposed upon it under Section 310(b) of the Trust Indenture
                  Act with respect to Securities of any series after written

of a Security who has been a bona fide Holder of a Security of such series for

with respect to all Securities, such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and the retiring Trustee an

desirable to transfer and confirm to, and to vest in, such successor Trustee all
the rights, powers, trusts and duties of the retiring Trustee with respect to
the Securities of that or those series to which the appointment of such
successor Trustee relates, (2) if the retiring Trustee is not retiring with
respect to all Securities, shall contain such provisions as shall be deemed
necessary or desirable to confirm that all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
as to which the retiring Trustee is not retiring shall continue to be vested in
the retiring Trustee, and (3) shall add to or change any of the provisions of
this Indenture as shall be necessary to provide for or facilitate the
administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust, that each such Trustee
shall be trustee of a trust or trusts hereunder separate and apart from any
trust or trusts hereunder administered by any other such Trustee and that no
Trustee shall be responsible for any notice given to, or received by, or any act
or failure to act on the part of any other Trustee hereunder, and, upon the
execution and delivery of such supplemental indenture, the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein, such retiring Trustee shall have no further responsibility for the

Trustee relates other than as hereinafter expressly set forth, and such

hereunder with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, subject to its claim, if any,
provided for in Section 606.

                  (3) Upon request of any Person appointed hereunder as a
successor Trustee, the Company shall execute any and all instruments for more

to in paragraph (1) or (2) of this Section, as the case may be.

                  (4) No Person shall accept its appointment hereunder as a
successor Trustee unless at the time of such acceptance such successor Person
shall be qualified and eligible under this Article.

                  Section 610. Merger, Conversion, Consolidation or Succession
                               to Business.

                  Any Corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any Corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any Corporation succeeding to all or substantially all of the
corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder, without the execution or filing of any paper or any further act on
the part of any of the parties hereto. In case any Securities shall have been
authenticated but not delivered by the Trustee then in office, any successor by
merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

                  Section 611. Appointment of Authenticating Agent.

                  The Trustee may appoint one or more Authenticating Agents
acceptable to the Company with respect to one or more series of Securities which
shall be authorized to act on behalf of the Trustee to authenticate Securities
of that or those series issued upon original issue, exchange, registration of
transfer, partial redemption or partial repayment or pursuant to Section 306,
and Securities so authenticated shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if authenticated
by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or 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
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent.

                  Each Authenticating Agent shall be acceptable to the Company
and, except as provided in or pursuant to this Indenture, shall at all times be
a corporation that would be permitted by the Trust Indenture Act to act as
trustee under an indenture qualified under the Trust Indenture Act, is
authorized under applicable law and by its charter to act as an Authenticating
Agent and has a combined capital and surplus (computed in accordance with
Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000. If at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect specified in this Section.

                  Any Corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any Corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any Corporation succeeding to all or
substantially all of the corporate agency or corporate trust business of an
Authenticating Agent, shall be the successor of such Authenticating Agent

                                       54
<PAGE>

hereunder, provided such Corporation shall be otherwise eligible under this
Section, without the execution or filing of any paper or any further act on the
part of the Trustee or the Authenticating Agent.

                  An Authenticating Agent may resign at any time by giving
written notice thereof to the Trustee and the Company. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall (i) mail written notice
of such appointment by first-class mail, postage prepaid, to all Holders of
Registered Securities, if any, of the series with respect to which such
Authenticating Agent shall serve, as their names and addresses appear in the
Security Register, and (ii) if Securities of the series are issued as Bearer
Securities, publish notice of such appointment at least once in an Authorized
Newspaper in the place where such successor Authenticating Agent has its
principal office if such office is located outside the United States. Any
successor Authenticating Agent, upon acceptance of its appointment hereunder,
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

                  The Company agrees to pay each Authenticating Agent from time
to time reasonable compensation for its services under this Section. If the
Trustee makes such payments, it shall be entitled to be reimbursed for such
payments, subject to the provisions of Section 606.

                  The provisions of Sections 308, 603 and 604 shall be
applicable to each Authenticating Agent.

                  If an Authenticating Agent is appointed with respect to one or
more series of Securities pursuant to this Section, the Securities of such
series may have endorsed thereon, in addition to or in lieu of the Trustee's
certificate of authentication, an alternate certificate of authentication in

execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as

                                Additional Amounts.

                  The Company covenants and agrees for the benefit of the
Holders of the Securities of each series that it will duly and punctually pay
the principal of, any premium and interest on and any Additional Amounts with
respect to the Securities of such series in accordance with the terms thereof,
any Coupons appertaining thereto and this Indenture. Any interest due on any
Bearer Security on or before the Maturity thereof, and any Additional Amounts
payable with respect to such interest, shall be payable only upon presentation
and surrender of the Coupons appertaining thereto for such interest as they
severally mature.

                  Section 1002. Maintenance of Office or Agency.

                  The Company shall maintain in each Place of Payment for any
series of Securities an Office or Agency where Securities of such series (but
not Bearer Securities, except as otherwise provided below, unless such Place of
Payment is located outside the United States) may be presented or surrendered
for payment, where Securities of such series may be surrendered for registration
of transfer or exchange, and where notices and demands to or upon the Company in
respect of the Securities of such series relating thereto and this Indenture may
be served. If Securities of a series are issuable as Bearer Securities, the
Company shall maintain, subject to any laws or regulations applicable thereto,
an Office or Agency in a Place of Payment for such series which is located
outside the United States where Securities of such series and any Coupons
appertaining thereto may be presented and surrendered for payment; provided,
however, that if the Securities of such series are listed on The Stock Exchange
of the United Kingdom and the Republic of Ireland or the Luxembourg Stock
Exchange or any other stock exchange located outside the United States and such
stock exchange shall so require, the Company shall maintain a Paying Agent in
London, Luxembourg or any other required city

                                       62
<PAGE>

located outside the United States, as the case may be, so long as the Securities
of such series are listed on such exchange. The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of such
Office or Agency. If at any time the Company shall fail to maintain any such
required Office or Agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, except that Bearer
Securities of such series and any Coupons appertaining thereto may be presented
and surrendered for payment at the place specified for the purpose with respect
to such Securities as provided in or pursuant to this Indenture, and the Company
hereby appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands.

                  Except as otherwise provided in or pursuant to this Indenture,
no payment of principal, premium, interest or Additional Amounts with respect to
Bearer Securities shall be made at any Office or Agency in the United States or
by check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, if
amounts owing with respect to any Bearer Securities shall be payable in Dollars,
payment of principal of, any premium or interest on and any Additional Amounts
with respect to any such Security may be made at the Corporate Trust Office of
the Trustee or any Office or Agency designated by the Company in the Borough of
Manhattan, The City of New York, if (but only if) payment of the full amount of
such principal, premium, interest or Additional Amounts at all offices outside
the United States maintained for such purpose by the Company in accordance with
this Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

                  The Company may also from time to time designate one or more
other Offices or Agencies where the Securities of one or more series may be
presented or surrendered for any or all such purposes and may from time to time
rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain
an Office or Agency in each Place of Payment for Securities of any series for
such purposes. The Company shall give prompt written notice to the Trustee of
any such designation or rescission and of any change in the location of any such
other Office or Agency. Unless otherwise provided in or pursuant to this
Indenture, the Company hereby designates as the Place of Payment for each series
of Securities the Borough of Manhattan, The City of New York, and initially
appoints the Corporate Trust Office of the Trustee as the Office or Agency of
the Company in the Borough of Manhattan, The City of New York for such purpose.
The Company may subsequently appoint a different Office or Agency in the Borough
of Manhattan, The City of New York for the Securities of any series.

                  Unless otherwise specified with respect to any Securities
pursuant to Section 301, if and so long as the Securities of any series (i) are
denominated in a Foreign Currency or (ii) may be payable in a Foreign Currency,
or so long as it is required under any other provision of this Indenture, then
the Company will maintain with respect to each such series of Securities, or as
so required, at least one exchange rate agent.

                  If the Company shall at any time act as its own Paying Agent
with respect to any series of Securities, it shall, on or before each due date
of the principal of, any premium or interest on or Additional Amounts with
respect to any of the Securities of such series, segregate and hold in trust for
the benefit of the Persons entitled thereto a sum in the Currency or Currencies
in which the Securities of such series are payable (except as otherwise
specified pursuant to Section 301 for the Securities of such series) sufficient
to pay the principal or any premium, interest or Additional Amounts so becoming
due until such sums shall be paid to such Persons or otherwise disposed of as
herein provided, and shall promptly notify the Trustee of its action or failure
so to act.

to any Securities of such series, deposit with any Paying Agent a sum (in the
Currency or Currencies described in the preceding paragraph) sufficient to pay
the principal or any premium, interest or Additional Amounts so becoming due,
such sum to be held in trust for the benefit of the Persons entitled thereto,
and (unless such Paying Agent is the Trustee) the Company will promptly notify
the Trustee of its action or failure so to act.

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

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

                  (2) give the Trustee notice of any default by the Company (or
any other obligor upon the Securities of such series) in the making of any
payment of principal, any premium or interest on or any Additional Amounts with
respect to the Securities of such series; and

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

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

                  Except as otherwise provided herein or pursuant hereto, any
money deposited with the Trustee or any Paying Agent, or then held by the
Company, in trust for the payment of the principal of, any premium or interest
on or any Additional Amounts with respect to any Security of any series or any
Coupon appertaining thereto and remaining unclaimed for two years after such
principal or any such premium or interest or any such Additional Amounts shall
have become due and payable shall be paid to the Company on Company Request, or
(if then held by the Company) shall be discharged from such trust; and the
Holder of such Security or any Coupon appertaining thereto shall thereafter, as
an unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in an Authorized Newspaper in each Place of Payment for such
series or to be mailed to Holders of Registered Securities of such series, or
both, notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication
or mailing nor shall it be later than two years after such principal and any
premium or interest or Additional Amounts shall have become due and payable, any
unclaimed balance of such money then remaining will be repaid to the Company.

                  Section 1004. Additional Amounts.

                  If any Securities of a series provide for the payment of
Additional Amounts, the Company agrees to pay to the Holder of any such Security
or any Coupon appertaining thereto Additional Amounts as provided in or pursuant
to this Indenture or such Securities. Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of or any premium or
interest on, or in respect of, any Security of any series or any Coupon or the
net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of Additional
Amounts provided by the terms of such series established hereby or pursuant
hereto to the extent that, in such context, Additional Amounts are, were or
would be payable in respect thereof pursuant to such terms, and express mention
of the payment of Additional Amounts (if applicable) in any provision hereof
shall not be construed as excluding Additional Amounts in those provisions
hereof where such express mention is not made.

                  Except as otherwise provided in or pursuant to this Indenture
or the Securities of the applicable series, if the Securities of a series
provide for the payment of Additional Amounts, at least 10 days prior to the
first Interest Payment Date with respect to such series of Securities (or if the
Securities of such series shall not bear interest prior to Maturity, the first
day on which a payment of principal is made), and at least 10 days prior to each
date of payment of principal or interest if there has been any change with
respect to the matters set forth in the below-mentioned Officers' Certificate,
the Company shall furnish to the Trustee and the principal Paying Agent or
Paying Agents, if other than the Trustee, an Officers' Certificate instructing
the Trustee and such Paying Agent or Paying Agents whether such payment of
principal of and premium, if any, or interest on the Securities of such series
shall be made to Holders of Securities of such series or the Coupons
appertaining thereto who are United States Aliens without withholding for or on

                                       65
<PAGE>

account of any tax, assessment or other governmental charge described in the
Securities of such series. If any such withholding shall be required, then such
Officers' Certificate shall specify by country the amount, if any, required to
be withheld on such payments to such Holders of Securities or Coupons, and the
Company agrees to pay to the Trustee or such Paying Agent the Additional Amounts
required by the terms of such Securities. The Company covenants to indemnify the
Trustee and any Paying Agent for, and to hold them harmless against, any loss,
liability or expense reasonably incurred without negligence or bad faith on
their part arising out of or in connection with actions taken or omitted by any
of them in reliance on any Officers' Certificate furnished pursuant to this
Section.

                  Section 1005. Limitation on Liens.

                  Nothing in this Indenture or in the Securities shall in any
way restrict or prevent the Company or any Subsidiary from issuing, assuming,
guaranteeing or otherwise incurring any indebtedness; provided, however, that
neither the Company nor any Subsidiary shall issue, assume or guaranty any
notes, bonds, debentures or other similar evidences of indebtedness for money
borrowed secured by any Lien on any asset now owned or hereafter acquired by it
without making effective provision whereby any and all Securities then or
thereafter outstanding shall be secured by a Lien equally and ratably with any
and all other obligations thereby secured, so long as any such obligations shall
be so secured. Notwithstanding the foregoing, the Company or any Subsidiary,
without so securing the Securities, may issue, assume or guaranty indebtedness
secured by the following Liens:

                  (a) Liens existing on the date of this Indenture or provided
                  for under the terms of agreements existing on the date hereof;

                  (b) Liens on property to secure (i) all or any portion of the
                  cost of exploration, production, gathering, processing,
                  marketing, drilling or development of such property, (ii) all
                  or any portion of the cost of acquiring, constructing,
                  altering, improving or repairing any property or assets, real
                  or personal, or improvements used in connection with such
                  property, and (iii) indebtedness incurred by the Company or
                  any Subsidiary to provide funds for the activities set forth
                  in clauses (i) and (ii) above;

                  (c) Liens which secure indebtedness owing by a Subsidiary to
                  the Company, or to one or more other Subsidiaries, or to the
                  Company and one or more other Subsidiaries;

                  (d) Liens on the property of any person existing at the time
                  such person becomes a Subsidiary;

                  (e) Liens on any property securing (i) indebtedness incurred
                  in connection with the construction, installation or financing
                  of pollution control or abatement facilities or other forms of
                  industrial revenue bond financing, (ii) indebtedness issued or
                  guaranteed by the United States, any state or any department,
                  agency or instrumentality of either or (iii) indebtedness
                  issued or guaranteed by (Y) a

                                       66
<PAGE>

                  foreign government, any state or any department, agency or
                  instrumentality of either or (Z) an international finance
                  agency or any division or department thereof, including the
                  World Bank, the International Finance Corp. and the
                  Multilateral Investment Guarantee Agency;

                  (f) any Lien extending, renewing or replacing (or successive
                  extensions, renewals or replacements of) any Lien of the type
                  set forth in paragraph (a) through (e) above, which Lien
                  exists on the date of this Indenture;

                  (g) any Ordinary Course Lien (as defined below) arising, and
                  only so long as continuing, in the ordinary course of the
                  Company's business; or

                  (h) Liens which secure Limited Recourse Indebtedness.

                  Notwithstanding the foregoing, the Company and any one or more
Subsidiaries may issue, assume or guaranty the following indebtedness secured by
Liens on assets without regard to the foregoing limitations: indebtedness in any
aggregate principal amount which, together with the aggregate outstanding
principal amount of all other indebtedness of the Company and its Subsidiaries
so secured (excluding indebtedness secured by the permitted Liens described
above), and the aggregate amount of Sale/Leaseback Transaction obligations which
would otherwise be subject to the provisions of Section 1006, does not at the
time such indebtedness is incurred exceed 10% of the Company's Consolidated Net
Worth as shown on the most recent audited consolidated balance sheet of the
Company and its Subsidiaries.

                  Notwithstanding the foregoing, nothing in this Section 1005
shall be deemed to prohibit or otherwise limit the following types of
transactions:

                  (1)(i) the sale, granting of Liens with respect to or other
                  transfer of crude oil, natural gas or other petroleum
                  hydrocarbons in place, for a period of time until, or in an
                  amount such that, the transferee will realize therefrom a
                  specified amount (however determined) of money or such crude
                  oil, natural gas or other petroleum hydrocarbons, or (ii) the
                  sale or other transfer of any other interest in property of
                  the character commonly referred to as a production payment,
                  overriding royalty, forward sales or similar interest; and

                  (2) the granting of Liens required by any contract or statute
                  in order to permit the Company or a Subsidiary to perform any
                  contract or subcontract made by it with or at the request of
                  the United States government or any foreign government or
                  international finance agency, any state or any department
                  thereof, or any agency or instrumentality thereof, or to
                  secure partial, progress, advance or other payments to the
                  Company or any Subsidiary by any such entity pursuant to the
                  provisions of any contract or statute.

                  "Lien" shall mean, with respect to any asset, any mortgage,
lien, pledge, security interest or encumbrances of any kind in respect of such
asset, whether or not filed, recorded or otherwise perfected under applicable
law. The Company or any Subsidiary shall be deemed to own subject to a Lien any
asset which it has acquired or holds subject to the interest of a vendor

                                       67
<PAGE>

or lessor under any conditional sale agreement, capital lease or other title
retention agreement relating to such asset. The right of set-off, whether by
operation of law or by contract, does not constitute a Lien unless there is a
related obligation to maintain a deposit of cash or other assets in respect of
which such right of set-off may be exercised.

                  "Ordinary Course Lien" shall mean:

                  (a) Liens for taxes, assessments or governmental changes or
                  levies on the property of the Company or any Subsidiary if the
                  same shall not at the time be delinquent or thereafter can be
                  paid without penalty, or are being contested in good faith and
                  by appropriate proceedings and for which adequate reserves in
                  accordance with generally accepted accounting principles shall
                  have been set aside on the books of the Company;

                  (b) Liens imposed by law, such as carriers', warehousemen's,
                  landlords' and mechanics' liens and other similar liens
                  arising in the ordinary course of business which secure
                  obligations not more than 60 days past due or which are being
                  contested in good faith by appropriate proceedings and for
                  which adequate reserves in accordance with generally accepted
                  accounting principles shall have been set aside on the books
                  of the Company;

                  (c) Liens arising out of pledges or deposits under worker's
                  compensation laws, unemployment insurance, old age pensions,
                  or other social security or retirement benefits, or similar
                  legislation;

                  (d) Utility easements, building restrictions and such other
                  encumbrances or charges against real property as are of a
                  nature generally existing with respect to properties of a
                  similar character and which do not in any material way affect
                  the marketability of the same or interfere with the use
                  thereof in the business of the Company or its Subsidiaries, as
                  the case may be;

                  (e) Liens arising under operating agreements or similar
                  agreements in respect of obligations which are not yet due or
                  which are being contested in good faith by appropriate
                  proceedings;

                  (f) Liens reserved in oil, gas and/or mineral leases for bonus
                  or rental payments and for compliance with the terms of such
                  leases;

                  (g) Liens pursuant to partnership agreements, oil, gas and/or
                  mineral leases, farm-out-agreements, division orders,
                  contracts for the sale, purchase, exchange, or processing of
                  oil, gas and/or other hydrocarbons, unitization and pooling
                  declarations and agreements, operating agreements, development
                  agreements, area of mutual interest agreements, forward sale
                  agreements, oil and gas delivery obligations, and other
                  agreements which are customary in the oil, gas and other
                  mineral exploration, development and production business and
                  in the business of processing of gas and gas condensate
                  production of the extraction of products therefrom;

                                       68
<PAGE>

                  (h) Liens on personal property (excluding the capital stock or
                  indebtedness of any Subsidiary) securing indebtedness maturing
                  not more than one year from the date of its creation; and

                  (i) Liens relating to a judgment or other court-ordered award
                  or settlement as to which the Company has not exhausted its
                  appellate rights.

                  "Consolidated Net Worth" means the consolidated stockholders'
equity of the Company, determined in accordance with generally accepted
accounting principles.

                  Section 1006. Limitation on Sale/Leaseback Transactions.

                  Neither the Company nor any Subsidiary will enter into any
Sale/Leaseback Transaction with any Person (other than the Company or a
Subsidiary) providing for a term of more than three years unless:

                  (a) the Company or such Subsidiary would be permitted,
                  pursuant to the terms of Section 1005, to incur indebtedness
                  in an aggregate principal amount equal to or exceeding the
                  value of the Sale/Leaseback Transaction secured by a Lien on
                  the property subject to such Sale/Leaseback Transaction;

                  (b) since the date of this Indenture and within a period
                  commencing six months prior to the Sale/Leaseback Transaction
                  and ending six months after the consummation thereof, the
                  Company or such Subsidiary expends for any property (including
                  amounts expended for the acquisition, exploration, drilling or
                  development thereof, or for additions, alterations,
                  improvements or repairs thereto) an amount up to the net
                  proceeds of such Sale/Leaseback Transaction, and the Company
                  elects to designate such amount as a credit against such
                  Sale/Leaseback Transaction (with any amount of such net
                  proceeds not being so designated to be applied as set forth in
                  paragraph (c) below); or

                  (c) the Company, during or immediately after the expiration of

                  retirement, redemption or defeasance of the Securities and its
                  other Senior Indebtedness an amount equal to the greater of
                  (i) the net proceeds of the Sale/Leaseback Transaction and
                  (ii) the fair value, in the opinion of the Board of Directors
                  of the Company, of the subject property of the Sale/Leaseback
                  Transaction at the time of such transaction (adjusted, in
                  either case, to reflect the remaining term of the lease and
                  any amount applied pursuant to paragraph (b) above), less an
                  amount equal to the principal amount of other Senior
                  Indebtedness voluntarily retired by the Company during such
                  12-month period.

         "Sale/Leaseback Transaction" means any arrangement providing for the
leasing to the Company or any Subsidiary by any Person (other than the Company
or a Subsidiary) of any property which has been, or is to be, sold or

instrumentality of either, (b) a foreign government, any state or any department
agency or instrumentality of either, or (c) an international finance agency or

                  Subject to Articles Eight and Fifteen, the Company shall do or
cause to be done all things necessary to preserve and keep in full force and
effect its corporate existence and that of each Subsidiary and their respective
rights (charter and statutory) and franchises; provided, however, that the
foregoing shall not obligate the Company or any Subsidiary to preserve any such
right or franchise if the Company or any Subsidiary shall determine that the
preservation thereof is no longer desirable in the conduct of its business or
the business of such Subsidiary.

                  Section 1008. Waiver of Certain Covenants.

                  The Company may omit in any particular instance to comply with
any term, provision or condition set forth in Sections 1005, 1006 or 1007 with
respect to the Securities of any series if before the time for such compliance
the Holders of at least a majority in principal amount of the Outstanding
Securities of such series, by Act of such Holders, either shall waive such
compliance in such instance or generally shall have waived compliance with such
term, provision or condition, but no such waiver shall extend to or affect such
term, provision or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of the Company and the
duties of the Trustee in respect of any such term, provision or condition shall
remain in full force and effect.

                  Section 1009. Company Statement as to Compliance; Notice of
                                Certain Defaults.

                  (1) The Company shall deliver to the Trustee, within 120

                  (a) a review of the activities of the Company during such year
                  and of its performance under this Indenture has been made
                  under his or her supervision, and

                  (b) to the best of his or her knowledge, based on such review,
                  (a) the Company has complied with all the conditions and
                  covenants imposed on it under this Indenture throughout such
                  year, or, if there has been a default in the fulfillment of
                  any such condition or covenant, specifying each such default
                  known to him or her and the nature and status thereof, and (b)
                  no event has occurred and

                                       70
<PAGE>

                  is continuing which is, or after notice or lapse of time or
                  both would become, an Event of Default, or, if such an event
                  has occurred and is continuing, specifying each such event
                  known to him and the nature and status thereof.

                  (2) The Company shall deliver to the Trustee, within five
days after the occurrence thereof, written notice of any Event of Default or any
event which after notice or lapse of time or both would become an Event of

                            REDEMPTION OF SECURITIES

                  Section 1101. Applicability of Article.

                  Redemption of Securities of any series at the option of the
Company as permitted or required by the terms of such Securities shall be made
in accordance with the terms of such Securities and (except as otherwise
provided herein or pursuant hereto) this Article.

                  Section 1102. Election to Redeem; Notice to Trustee.

                  The election of the Company to redeem any Securities shall be
evidenced by or pursuant to a Board Resolution or an Officer's Certificate. In
case of any redemption at the election of the Company of (a) less than all of
the Securities of any series or (b) all of the Securities of any series, with
the same issue date, interest rate or formula, Stated Maturity and other terms,
the Company shall, at least 60 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date and of the principal amount of Securities of
such series to be redeemed.

                  Section 1103. Selection by Trustee of Securities to be
                                Redeemed.

                  If less than all of the Securities of any series with the same
issue date, interest rate or formula, Stated Maturity and other terms are to be
redeemed, the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee from the Outstanding
Securities of such series not previously called for redemption, by such method
as the Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions of the principal amount of Registered
Securities of such series; provided, however, that no such partial redemption
shall reduce the portion of the principal amount of a Registered Security of
such series not redeemed to less than the minimum denomination for a Security of
such series established herein or pursuant hereto.

                  The Trustee shall promptly notify the Company and the Security
Registrar (if other than itself) in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption,
the principal amount thereof to be redeemed.

                                       71
<PAGE>

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

                  Section 1104. Notice of Redemption.

                  Notice of redemption shall be given in the manner provided in
Section 106, not less than 30 nor more than 60 days prior to the Redemption
Date, unless a shorter period is specified in the Securities to be redeemed, to
the Holders of Securities to be redeemed. Failure to give notice by mailing in
the manner herein provided to the Holder of any Registered Securities designated
for redemption as a whole or in part, or any defect in the notice to any such
Holder, shall not affect the validity of the proceedings for the redemption of
any other Securities or portion thereof.

                  Any notice that is mailed to the Holder of any Registered
Securities in the manner herein provided shall be conclusively presumed to have
been duly given, whether or not such Holder receives the notice.

                  All notices of redemption shall state:

                  (1) the Redemption Date,

                  (2) the Redemption Price,

                  (3) if less than all Outstanding Securities of any series are
to be redeemed, the identification (and, in the case of partial redemption, the
principal amount) of the particular Security or Securities to be redeemed,

                  (4) in case any Security is to be redeemed in part only, the
notice which relates to such Security shall state that on and after the
Redemption Date, upon surrender of such Security, the Holder of such Security
will receive, without charge, a new Security or Securities of authorized
denominations for the principal amount thereof remaining unredeemed,

                  (5) that, on the Redemption Date, the Redemption Price shall
become due and payable upon each such Security or portion thereof to be
redeemed, and, if applicable, that interest thereon shall cease to accrue on and
after said date,

                  (6) the place or places where such Securities, together (in
the case of Bearer Securities) with all Coupons appertaining thereto, if any,
maturing after the Redemption Date, are to be surrendered for payment of the
Redemption Price and any accrued interest and Additional Amounts pertaining
thereto,

                  (7) that, unless otherwise specified in such notice, Bearer
Securities of any series, if any, surrendered for redemption must be accompanied
by all Coupons maturing subsequent to the date fixed for redemption or the
amount of any such missing Coupon or

                                       72
<PAGE>

Coupons will be deducted from the Redemption Price, unless security or indemnity
satisfactory to the Company, the Trustee and any Paying Agent is furnished,

                  (8) if Bearer Securities of any series are to be redeemed and
any Registered Securities of such series are not to be redeemed, and if such
Bearer Securities may be exchanged for Registered Securities not subject to
redemption on the Redemption Date pursuant to Section 305 or otherwise, the last
date, as determined by the Company, on which such exchanges may be made,

                  (9) the CUSIP number or the Euroclear or the Cedel reference
numbers of such Securities, if any (or any other numbers used by a Depository to
identify such Securities).

                  A notice of redemption mailed as contemplated by Section 106
need not identify particular Registered Securities to be redeemed.

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

                  Section 1105. Deposit of Redemption Price.

                  On or prior to any Redemption Date, the Company shall deposit,
with respect to the Securities of any series called for redemption pursuant to
Section 1104, with the Trustee or with a Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust as provided in
Section 1003) an amount of money in the applicable Currency sufficient to pay
the Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date, unless otherwise specified pursuant to Section 301 or in the
Securities of such series) any accrued interest on and Additional Amounts with
respect thereto, all such Securities or portions thereof which are to be
redeemed on that date.

                  Section 1106. Securities Payable on Redemption Date.

                  Notice of redemption having been given as aforesaid, the
Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and from and after such date
(unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest and the Coupons
for such interest appertaining to any Bearer Securities so to be redeemed,
except to the extent provided below, shall be void. Upon surrender of any such
Security for redemption in accordance with said notice, together with all
Coupons, if any, appertaining thereto maturing after the Redemption Date, such
Security shall be paid by the Company at the Redemption Price, together with any
accrued interest and Additional Amounts to the Redemption Date; provided,
however, that, except as otherwise provided in or pursuant to this Indenture or
the Bearer Securities of such series, installments of interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only upon presentation and surrender of Coupons for such interest (at an
Office or Agency located outside the United States except as

                                       73
<PAGE>

otherwise provided in Section 1002), and provided, further, that, except as
otherwise specified in or pursuant to this Indenture or the Registered
Securities of such series, installments of interest on Registered Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the Regular Record Dates therefor
according to their terms and the provisions of Section 307.

                  If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant Coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing Coupons, or the surrender of such missing
Coupon or Coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to the Trustee or any Paying Agent any such missing Coupon in
respect of which a deduction shall have been made from the Redemption Price,
such Holder shall be entitled to receive the amount so deducted; provided,
however, that any interest or Additional Amounts represented by Coupons shall be
payable only upon presentation and surrender of those Coupons at an Office or
Agency for such Security located outside of the United States except as
otherwise provided in Section 1002.

                  If any Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal and any premium, until
paid, shall bear interest from the Redemption Date at the rate prescribed
therefor in the Security.

                  Section 1107. Securities Redeemed in Part.

                  Any Registered Security which is to be redeemed only in part
shall be surrendered at any Office or Agency for such Security (with, if the
Company or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or his attorney duly authorized in writing) and the
Company shall execute and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge, a new Registered Security or
Securities of the same series, containing identical terms and provisions, of any
authorized denomination as requested by such Holder in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered. If a Security in global form is so surrendered, the
Company shall execute, and the Trustee shall authenticate and deliver to the
U.S. Depository or other Depository for such Security in global form as shall be
specified in the Company Order with respect thereto to the Trustee, without
service charge, a new Security in global form in a denomination equal to and in
exchange for the unredeemed portion of the principal of the Security in global
form so surrendered.

                       REPAYMENT AT THE OPTION OF HOLDERS

                  Section 1201. Applicability of Article.

                  Securities of any series which are repayable at the option of
the Holders thereof before their Stated Maturity shall be repaid in accordance
with the terms of the Securities of such series. The repayment of any principal
amount of Securities pursuant to such option of the Holder to require repayment
of Securities before their Stated Maturity, for purposes of Section 309, shall
not operate as a payment, redemption or satisfaction of the Indebtedness
represented by such Securities unless and until the Company, at its option,
shall deliver or surrender the same to the Trustee with a directive that such
Securities be cancelled. Notwithstanding anything to the contrary contained in
this Section 1201, in connection with any repayment of Securities, the Company
may arrange for the purchase of any Securities by an agreement with one or more
investment bankers or other purchasers to purchase such Securities by paying to
the Holders of such Securities on or before the close of business on the
repayment date an amount not less than the repayment price payable by the
Company on repayment of such Securities, and the obligation of the Company to
pay the repayment price of such Securities shall be satisfied and discharged to
the extent such payment is so paid by such purchasers.

                  Section 1301. Applicability of Article.

                  Whenever this Indenture provides for (i) any action by, or the
determination of any of the rights of, Holders of Securities of any series in
which not all of such Securities are denominated in the same Currency, or (ii)
any distribution to Holders of Securities, in the absence of any provision to
the contrary in the form of Security of any particular series or pursuant to
this Indenture or the Securities, any amount in respect of any Security
denominated in a Currency other than Dollars shall be treated for any such
action or distribution as that amount of Dollars that could be obtained for such
amount on such reasonable basis of exchange and as of the record date with
respect to Registered Securities of such series (if any) for such action,
determination of rights or distribution (or, if there shall be no applicable
record date, such other date reasonably proximate to the date of such action,
determination of rights or distribution) as the Company may specify in a written
notice to the Trustee or, in the absence of such written notice, as the Trustee
may determine.

                        MEETINGS OF HOLDERS OF SECURITIES

                  Section 1401. Purposes for Which Meetings May Be Called.

                  A meeting of Holders of Securities of any series may be called
at any time and from time to time pursuant to this Article to make, give or take
any request, demand, authorization, direction, notice, consent, waiver or other
Act provided by this Indenture to be made, given or taken by Holders of
Securities of such series.

                  Section 1402. Call, Notice and Place of Meetings.

                  (1) The Trustee may at any time call a meeting of Holders of
Securities of any series for any purpose specified in Section 1401, to be held
at such time and at such place in the Borough of Manhattan, The City of New
York, or, if Securities of such series have been issued in whole or in part as
Bearer Securities, in London or in such place outside the United States as the
Trustee shall determine. Notice of every meeting of Holders of Securities of any
series, setting forth the time and the place of such meeting and in general
terms the action proposed to be taken at such meeting, shall be given, in the
manner provided in Section 106, not less than 21 nor more than 180 days prior to
the date fixed for the meeting.

                  (2) In case at any time the Company (by or pursuant to a Board
Resolution) or the Holders of at least 10% in principal amount of the
Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified in
Section 1401, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have mailed
notice of or made the first publication of the notice of such meeting within 21
days after receipt of such request (whichever shall be required pursuant to
Section 106) or shall not thereafter proceed to cause the meeting to be held as
provided herein, then the Company or the Holders of Securities of such series in
the amount above specified, as the case may be, may determine the time and the
place in the Borough of Manhattan, The City of New York, or, if Securities of
such series are to be issued as Bearer Securities, in London for such meeting
and may call such meeting for such purposes by giving notice thereof as provided
in clause (1) of this Section.

                  Section 1403. Persons Entitled to Vote at Meetings.

present or to speak at any meeting of Holders of Securities of any series shall
be the Persons entitled to vote at such meeting and their counsel, any
representatives of the Trustee and its counsel and any representatives of the
Company and its counsel.

                  The Persons entitled to vote a majority in principal amount of
the Outstanding Securities of a series shall constitute a quorum for a meeting
of Holders of Securities of such series; provided, however, that if any action
is to be taken at such meeting with respect to a consent or waiver which this
Indenture expressly provides may be given by the Holders of at least 66-2/3% in
principal amount of the Outstanding Securities of a series, the Persons entitled
to vote 66-2/3% in principal amount of the Outstanding Securities of such series
shall constitute a quorum. In the absence of a quorum within 30 minutes after
the time appointed for any such meeting, the meeting shall, if convened at the
request of Holders of Securities of such series, be dissolved. In any other case
the meeting may be adjourned for a period of not less than 10 days as determined
by the chairman of the meeting prior to the adjournment of such meeting. In the
absence of a quorum at any such adjourned meeting, such adjourned meeting may be
further adjourned for a period of not less than 10 days as determined by the
chairman of the meeting prior to the adjournment of such adjourned meeting.
Notice of the reconvening of any adjourned meeting shall be given as provided in
Section 1402(1), except that such notice need be given only once not less than
five days prior to the date on which the meeting is scheduled to be reconvened.
Notice of the reconvening of an adjourned meeting shall state expressly the
percentage, as provided above, of the principal amount of the Outstanding
Securities of such series which shall constitute a quorum.

                  Except as limited by the proviso to Section 902, any
resolution presented to a meeting or adjourned meeting duly reconvened at which
a quorum is present as aforesaid may be adopted only by the affirmative vote of
the Holders of a majority in principal amount of the Outstanding Securities of
that series; provided, however, that, except as limited by the proviso to
Section 902, any resolution with respect to any consent or waiver which this
Indenture expressly provides may be given by the Holders of at least 66-2/3% in
principal amount of the Outstanding Securities of a series may be adopted at a
meeting or an adjourned meeting duly convened and at which a quorum is present
as aforesaid only by the affirmative vote of the Holders of 66-2/3% in principal
amount of the Outstanding Securities of that series; and provided, further,
that, except as limited by the proviso to Section 902, any resolution with
respect to any request, demand, authorization, direction, notice, consent,
waiver or other Act which this Indenture expressly provides may be made, given
or taken by the Holders of a specified percentage, which is less than a
majority, in principal amount of the Outstanding Securities of a series may be
adopted at a meeting or an adjourned meeting duly reconvened and at which a
quorum is present as aforesaid by the affirmative vote of the Holders of such
specified percentage in principal amount of the Outstanding Securities of such
series.

                  Any resolution passed or decision taken at any meeting of
Holders of Securities of any series duly held in accordance with this Section
shall be binding on all the Holders of Securities of such series and the Coupons
appertaining thereto, whether or not such Holders were present or represented at
the meeting.

                                Adjournment of Meetings.

                  (1) Notwithstanding any other provisions of this Indenture,
the Trustee may make such reasonable regulations as it may deem advisable for
any meeting of Holders of Securities of such series in regard to proof of the
holding of Securities of such series and of the appointment of proxies and in
regard to the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem
appropriate. Except as otherwise permitted or required by any such regulations,
the holding of Securities shall be proved in the manner specified in Section 104
and the appointment of any proxy shall be proved in the manner specified in
Section 104 or by having the signature of the person executing the proxy
witnessed or guaranteed by any trust company, bank or banker authorized by
Section 104 to certify to the holding of Bearer Securities. Such regulations may
provide that written instruments appointing proxies, regular on their face, may
be presumed valid and genuine without the proof specified in Section 104 or
other proof.

                  (2) The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 1402(2), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

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

                  (4) Any meeting of Holders of Securities of any series duly
called pursuant to Section 1402 at which a quorum is present may be adjourned
from time to time by Persons entitled to vote a majority in principal amount of
the Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

                  Section 1406. Counting Votes and Recording Action of Meetings.

                  The vote upon any resolution submitted to any meeting of
Holders of Securities of any series shall be by written ballots on which shall
be subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in triplicate of all votes cast at the meeting.

                                       78

A record, at least in triplicate, of the proceedings of each meeting of Holders
of Securities of any series shall be prepared by the secretary of the meeting
and there shall be attached to said record the original reports of the
inspectors of votes on any vote by ballot taken thereat and affidavits by one or
more persons having knowledge of the facts setting forth a copy of the notice of
the meeting and showing that said notice was given as provided in Section 1402
and, if applicable, Section 1404. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

                  (a) Any person (for purposes of paragraph (a) of this Section
                  1501(1) only, the term "person" shall mean a "person" as

                  deemed the beneficial owner of (1) any securities tendered
                  pursuant to a tender offer or exchange offer made by or on
                  behalf of such person, or its Affiliates or Associates, until

                  the Office or Agency to collect payment;

                  (g) that the Change in Control Purchase Price for any Security
                  as to which a Change in Control Purchase Notice has been duly
                  given and not withdrawn will be paid promptly following the
                  later of the Change in Control Purchase Date or the time of
                  surrender of such Security as described in (f);

in the Securities.

         The delivery of the Security, by hand or by registered mail prior to,
on or after the Change in Control Purchase Date (together with all necessary
endorsements), to the Trustee or to the Office or Agency shall be a condition
precedent to the obligation of the Company to pay to the Holder the Change in
Control Purchase Price therefor; provided, however, that such Change in Control
Purchase Price shall be so paid pursuant to this Section 1501 only if the
Security so delivered to the Trustee or such Office or Agency shall conform in

                  Section 1502. Effect of Change in Control Purchase Notice.

                  Upon receipt by the Company of the Change in Control Purchase
Notice specified in Section 1501(3), the Holder of the Security in respect of
which such Change in Control Purchase Notice was given shall (unless such Change
in Control Purchase Notice is withdrawn as specified in the following paragraph)
thereafter be entitled to receive solely the Change in Control Purchase Price
with respect to such Security. Such Change in Control Purchase Price shall be
paid to such Holder promptly following the later of (x) the Change in Control
Purchase Date, as the case may be, with respect to such Security (provided the
conditions in Section 1501(3), as applicable, have been satisfied) and (y) the
time of delivery of such Security to the Trustee or to the Office or Agency by
the Holder thereof in the manner required by Section 1501(3), as applicable.

                  A Change in Control Purchase Notice may be withdrawn by means
of a written notice of withdrawal delivered to the office of the Trustee or to
the Office or Agency at any time prior to the close of business on the Change in
Control Purchase Date, specifying:

                  (1) the certificate number or numbers of the Security or
                  Securities in respect of which such notice of withdrawal is
                  being submitted;

                  (2) the principal amount of the Security or Securities with
                  respect to which such notice of withdrawal is being submitted;
                  and

                  (3) the principal amount, if any, of such Security or
                  Securities which remains subject to the original Change in
                  Control Purchase Notice, and which has been and will be
                  delivered for purchase by the Company.

                  There shall be no purchase of any Securities pursuant to
Section 1501 if there has occurred and in continuing an Event of Default (other
than a default in the payment of the Change in Control Purchase Price).

                  Section 1503. Deposit of Change in Control Purchase Price.

                  Prior to 12:00 Noon (local time in The City of New York) on
the Business Day following the Change in Control Purchase Date, the Company
shall deposit with the Trustee (or, if the Company or a Subsidiary or an
Affiliate of either of them is acting as Paying Agent, shall segregate and hold
in trust as provided in Section 1003) an amount of cash in immediately available
funds or securities, if expressly permitted hereunder, sufficient to pay the
aggregate Change in Control Purchase Price of all the Securities or portions
thereof which are to be purchased. If a deposit is made with the Trustee of the
aforesaid amount of cash or securities, the Securities or portions thereof with
respect to which a Change in Control Purchase Notice has been delivered and not
validly withdrawn shall become due and payable as of the Business Day following
the applicable Change in Control Purchase Date, and on and after such date
interest payable in respect of such Securities shall cease and all other rights
of the Holders thereof shall terminate, other than the right to receive the
Change in Control Purchase Price upon delivery of such Securities to the
Trustee.

                             AMENDMENT TO INDENTURE

         SECTION 2.1. Section 101 of the Indenture is supplemented and amended
to add the following term:

                  "Senior Indebtedness" means the principal of, premium, if any,
interest on, and any other payment due pursuant to any of the following, whether
outstanding as of the date of execution of the Indenture or thereafter incurred,
created or assumed:

                  (a) all indebtedness of the Company or any Subsidiary for
         money borrowed (including, without limitation, any indebtedness secured
         by a mortgage, conditional sales contract or other lien which is (i)
         given to secure all or part of the purchase price of property subject
         thereto, whether given to the vendor of such property or to another, or
         (ii) existing on property at the time of acquisition thereof);

                  (b) all indebtedness of the Company or any Subsidiary
         evidenced by notes, debentures, bonds, commercial paper or other
         securities sold by the Company or any Subsidiary for money;

                  (c) all lease obligations of the Company or any Subsidiary
         which are capitalized on the books of the Company in accordance with
         GAAP;

                  (d) all indebtedness of others of the kinds described in
         either of the preceding clauses (a) or (b) and all lease obligations of
         others of the kind described in the preceding clause (c) assumed by or
         guaranteed in any manner by the Company or any Subsidiary or in effect
         guaranteed by the Company or any Subsidiary through an agreement to
         purchase, contingent or otherwise;

                  (e) all obligations of the Company or any Subsidiary with
         respect to letters of credit issued in connection with indebtedness of
         others of the kind described in the preceding clauses (a) or (b) or
         lease obligations of the kind described in the preceding clause (c);

         described in the preceding clause (e);

which, in each case, is an obligation payable by its terms more than one year
from the date of incurrence thereof and should be shown on a balance sheet as a
liability under GAAP; unless, in the case of any particular indebtedness, lease,
obligation, renewal, extension or refunding, the instrument or lease creating or
evidencing the same or the assumption or guarantee of the same expressly
provides that such indebtedness, lease, obligation, renewal, extension or
refunding is subordinate in right of payment to or is not at least pari passu
with the Securities. Notwithstanding the foregoing, "Senior Indebtedness" does
not include indebtedness owing, directly or indirectly, to any Affiliate or
employee of the Company or arising under or in respect of any employee benefit
plan of the Company or any of its Affiliates.
