         SECTION 201.  FORMS GENERALLY.

         The Registered Securities, if any, of each series and the Bearer
Securities, if any, of each series and related coupons shall be in substantially
the form (including temporary or permanent global form) as shall be established
by or pursuant to a Board Resolution or in one or more indentures supplemental
hereto, in each case with such appropriate insertions, omissions, substitutions
and other variations as are required or permitted by this Indenture, and may

endorsements placed thereon as may be required to comply with law, or with the
rules of any securities exchange or to conform to general usage, all as may,
consistently herewith, be determined by the officers executing such Securities
or coupons, as evidenced by their execution of the Securities or coupons. If
temporary Securities of any series are issued in global form as permitted by
Section 304, the form thereof shall be established as provided in the preceding
sentence. A copy of the Board Resolution establishing the forms of Securities or
coupons of any series (or any such temporary global Security) shall be certified
by the Secretary or an Assistant Secretary of the Company and delivered to the
Trustee at or prior to the delivery of the Company Order contemplated by Section
303 for the authentication and delivery of such Securities (or any such
temporary global Security) or coupons.

         Unless otherwise specified as contemplated by Section 301, Securities
in bearer form shall have interest coupons attached.

         The definitive Securities and coupons, if any, shall be typed, printed,
lithographed or engraved or may be produced in any other manner, all as
determined by the officers executing such Securities, as evidenced by their
execution of such Securities or coupons.

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

         The Trustee's certificates of authentication shall be in substantially

                                        as Trustee



                                        By:
                                            -----------------------------------

         SECTION 203.  SECURITIES IN GLOBAL FORM; CERTAIN BOOK-ENTRY PROVISIONS.

         If Securities of a series are issuable in global form, as specified as
contemplated by Section 301, then, notwithstanding clause (10) of Section 301
and the provisions of Section 302, any such Security shall represent such of the
Outstanding Securities of such series as shall be specified therein and may
provide that it shall represent the aggregate amount of Outstanding Securities
from time to time endorsed thereon and that the aggregate amount of Outstanding
Securities represented thereby may be reduced or increased, as appropriate, to
reflect exchanges or redemptions. Any endorsement of a Security in global form
to reflect the amount, or any increase or decrease in the amount, of Outstanding
Securities represented thereby shall be made by the Trustee (i) in such manner
and upon instructions given by such Person or Persons as shall be specified
therein or in the Company Order to be delivered to the Trustee pursuant to
Section 303 or Section 304 or (ii) otherwise in accordance with written
instructions as is customary for the Depositary for such Security, from such
Depositary or its nominee on behalf of any Person having a beneficial interest
in such global Security. Subject to the provisions of Section 303 and, if
applicable, Section 304, the Trustee shall deliver and redeliver any Security in
permanent global form in the manner and upon instructions given by the Person or
Persons specified therein or in the applicable Company Order. With respect to
the Securities of any series that are represented by a Book-Entry Security, the
Company authorizes the execution and delivery by the Trustee of a letter of
representations or other similar agreement or instrument in the form customarily
provided for by the Depositary appointed with respect to such Security. Any
Book-Entry Security may be deposited with the Depositary or its nominee, or
remain in the custody of the trustee or the Security Custodian therefor pursuant
to a FAST Balance Certificate Agreement or similar agreement between the Trustee
and the Depositary. If a Company Order pursuant to Section 303 or 304 has been,
or simultaneously is, delivered, any instructions by the Company with respect to
endorsement or delivery or redelivery of a Security in global form shall be in
writing but need not comply with Section 1501 and need not be accompanied by an
Opinion of Counsel.


                                       12
<PAGE>   20

         The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 1501 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 303.

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

         SECTION 204.  FORM OF LEGEND FOR BOOK-ENTRY SECURITIES.

         Any Book-Entry Security authenticated and delivered hereunder shall
bear a legend in substantially the following form:

         "This Security is a Book-Entry Security within the meaning of the
Indenture hereinafter referred to and is registered in the name of a Depositary
or a nominee of a Depositary. This Security is exchangeable for Securities
registered in the name of a Person other than the Depositary or its nominee only
in the limited circumstances described in the Indenture, and no transfer of this
Security (other than a transfer of this Security as a whole by the Depositary to
a nominee of the Depositary or by a nominee of the Depositary to the Depositary
or another nominee of the Depositary or by the Depositary or any nominee thereof
to a successor Depositary or any nominee of such successor Depositary) may be
registered except in such limited circumstances."

         The Securities may be issued from time to time in one or more series,
and each such series shall rank equally and pari passu with each other series.

Certificate, or established in one or more indentures supplemental hereto, prior

         under which any such exchanges may occur, if other than in the manner
         provided in Section 305;

         of the series shall be payable, if other than the Person in whose name

         the close of business on the Regular Record Date for such interest, the
         manner in which, or the Person to whom, any interest on any Bearer

         severally mature and the extent to which, or the manner in which, any
         interest payable on a temporary global Security on an Interest Payment
         Date will be paid if other than in the manner provided in Section 304;

                  (5) the date or dates on which the principal of and premium,
         if any, on the Securities of the series is payable or the method of
         determination thereof;

                  (6) the rate or rates at which the Securities of the series
         shall bear interest, if any, or the method by which such rate or rates
         shall be determined, the date or dates from which any such interest
         shall accrue, the Interest Payment Dates on which any such interest
         shall be payable, and the Regular Record Date for any interest payable

         and under what circumstances, additional amounts with respect to such
         Securities shall be payable as set forth in Section 1004;

                  (7) the place or places where, subject to the provisions of
         Section 1002, the principal of and any premium and interest on
         Securities of the series shall be payable, any Registered Securities of
         the series may be surrendered for registration of transfer,

         Securities of the series may be surrendered for exchange and notices
         and demands to or upon the Company in respect of the Securities of the

         the duration of such extensions;

                  (22) any other terms of the series (which terms shall not be

<PAGE>   24
         All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except, in the
case of Registered Securities, as to denomination and except as may otherwise be
provided in or pursuant to the Board Resolution referred to above and (subject
to Section 303) set forth, or determined in the manner provided, in the
Officers' Certificate referred to above or in any such indenture supplemental
hereto.

         All Securities of any one series need not be issued at the same time
and, unless otherwise provided, a series may be reopened, without the consent of
the Holders, for issuances of additional Securities of such series.

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

         SECTION 302. DENOMINATIONS.

         Unless otherwise provided as contemplated by Section 301 with respect
to any series of Securities, any Registered Securities of a series shall be
issuable in denominations of $1,000 and any integral multiple thereof and any
Bearer Securities of a series shall be issuable in the denomination of $5,000.

         SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

         The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its President, or a Vice President of the Company,
attested by its Secretary or one of its Assistant Secretaries. The signature of
any of these officers on the Securities may be manual or facsimile. Coupons
shall bear the facsimile signature of the Chief Financial Officer, the Treasurer
or any Assistant Treasurer of the Company.

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

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series, together with
any coupons appertaining thereto, executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance


                                       17
<PAGE>   25


with the Company Order shall authenticate and deliver such Securities; provided,
however, that, (i) in the case of Securities of a series that are not to be
originally issued at one time, the Trustee shall authenticate and deliver or
make available for delivery such Securities from time to time in accordance with
such other procedures (including, without limitation, the receipt by the Trustee
of oral or electronic instructions from the Company or its duly authorized
agents, promptly confirmed in writing) acceptable to the Trustee as may be
specified by or pursuant to a Company Order delivered to the Trustee prior to
the time of the first authentication of Securities of such series, and (ii)
unless otherwise provided with respect to such series, in connection with its
original issuance, no Bearer Security shall be mailed or otherwise delivered to
any location in the United States; and provided, further, that, unless otherwise
provided with respect to such series, a Bearer Security may be delivered in
connection with its original issuance only if the Person entitled to receive
such Bearer Security shall have furnished a certificate in the form set forth in
Exhibit A to this Indenture, dated no earlier than the Certification Date. If
any Security shall be represented by a permanent global Bearer Security, then,
for purposes of this Section and Section 304, the notation of a beneficial
owner's interest therein upon original issuance of such Security or upon
exchange of a portion of a temporary global Security shall be deemed to be
delivery in connection with its original issuance of such beneficial owner's
interest in such permanent global Security. Except as permitted by Section 306,
the Trustee shall not authenticate and deliver any Bearer Security unless all
appurtenant coupons for interest then matured have been detached and canceled.

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

               (1) that the forms of such Securities and coupons established by
         or pursuant to a Board Resolution as permitted by Section 201 have been
         established in conformity with the provisions of this Indenture;

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

               (3) that such Securities, together with any coupons appertaining
         thereto, when authenticated and delivered by the Trustee and issued by
         the Company in the manner and subject to any conditions specified in
         such Opinion of Counsel, will constitute valid and legally binding
         obligations of the Company enforceable in accordance with their terms,
         subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
         moratorium and similar laws of general applicability relating to or
         affecting creditors' rights and to general equity principles; provided,
         that such Opinion


                                       18
<PAGE>   26


         of Counsel need express no opinion as to whether a court in the United
         States would render a money judgment in currency other than that of the
         United States.

         The Trustee shall not be required to authenticate such Securities the
forms or terms of which have been established by or pursuant to a Board
Resolution 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.

         Notwithstanding the provisions of Section 301 and of the two preceding
paragraphs, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraphs at or prior to the time
of authentication of each Security of such series if such documents are
delivered at or prior to the authentication upon issuance of the first Security
of such series to be issued.

         After the original issuance of the first Security of such series to be
issued, any separate request by the Company that the Trustee authenticate
Securities of such series for original issuance will be deemed to be a
certification by the Company (which, subject to Section 601, the Trustee shall
be fully protected in relying on) that it is in compliance with all conditions
precedent provided for in this Indenture relating to the authentication and
delivery of such Securities.

         Each Registered Security shall be dated the date of its authentication;
and each Bearer Security shall be dated as of the date of original issuance of
the first Security of such series to be issued.

         No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security, or the Security to which such coupon appertains, a certificate of
authentication substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any Security shall be
conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered hereunder. Notwithstanding the foregoing, if any
Security shall have been authenticated and delivered hereunder but never issued
and sold by the Company, and the Company shall deliver such Security to the
Trustee for cancellation as provided in Section 309 together with a written
statement (which need not comply with Section 1501 and need not be accompanied
by an Opinion of Counsel) stating that such Security has never been issued and
sold by the Company, for all purposes of this Indenture such Security shall be
deemed never to have been authenticated and delivered hereunder and shall never
be entitled to the benefits of this Indenture.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form or, if authorized, in bearer form with one or
more coupons or without coupons, and with such appropriate insertions,
omissions, substitutions and other variations as the officers executing such
Securities may determine, as evidenced by their execution of such Securities. In
the case of any series issuable as Bearer Securities, such temporary Securities
may be in global form. A temporary Bearer Security shall be delivered only in
compliance with the conditions set forth in Section 303.

         Except in the case of temporary Securities in global form (which shall
be exchanged in accordance with the provisions of the following paragraphs), if
temporary Securities of any series are issued, the Company will cause definitive
Securities of that series to be prepared without unreasonable delay. After the
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of
the Company maintained pursuant to Section 1002 in a Place of Payment for such
series for the purpose of exchanges of Securities of such series without charge
to the Holder. Upon surrender for cancellation of any one or more temporary
Securities of any series (accompanied by any unmatured coupons appertaining
thereto) the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like aggregate principal amount of definitive
Securities of the same series and of like tenor of authorized denominations;
provided, however, that no definitive Bearer Security shall be issued in
exchange for a temporary Registered Security.

         If temporary Securities of any series are issued in global form, any
such temporary global Security shall, unless otherwise provided therein, be
delivered to the London office of a depositary or common depositary (the "Common
Depositary"), for the benefit of Euro- clear and CEDEL S.A., for credit to the
respective accounts of the beneficial owners of such Securities (or to such
other accounts as they may direct).

         Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Security of a series (the "Exchange Date"), the Company shall deliver to the
Trustee definitive Securities of that series in aggregate principal amount equal
to the principal amount of such temporary global Security, executed by the
Company. On or after the Exchange Date such temporary global Security shall be
surrendered by the Common Depositary to the Trustee, as the Company's agent for
such purpose, to be exchanged, in whole or from time to time in part, for
definitive Securities of that series without charge and the Trustee shall
authenticate and deliver, in exchange for each portion of such temporary global
Security, a like aggregate principal


                                       20
<PAGE>   28


amount of definitive Securities of the same series of authorized denominations
and of like tenor as the portion of such temporary global Security to be
exchanged; provided, however, that, unless otherwise specified in such temporary
global Security, upon such presentation by the Common Depositary, such temporary
global Security is accompanied by a certificate dated the Exchange Date or a
subsequent date and signed by Euro-clear as to the portion of such temporary
global Security held for its account then to be exchanged and a certificate
dated the Exchange Date or a subsequent date and signed by CEDEL S.A. as to the
portion of such temporary global Security held for its account then to be
exchanged, each in the form set forth in Exhibit B to this Indenture. The
definitive Securities to be delivered in exchange for any such temporary global
Security shall be in bearer form, registered form, permanent global bearer form
or permanent global registered form, or any combination thereof, as specified as
contemplated by Section 301, and if any combination thereof is so specified, as
requested by the beneficial owner thereof; provided, however, that no definitive
Bearer Security or permanent global Security shall be delivered in exchange for
a temporary Bearer Security except in compliance with the conditions set forth
in Section 303.

         Unless otherwise specified in the temporary global Security, the
interest of a beneficial owner of Securities of a series in a temporary global
Security shall be exchanged on the Exchange Date for definitive Securities (and
where the form of the definitive Securities is not specified by the Holder for
an interest in a permanent global Security) of the same series and of like tenor
unless, on or prior to the Exchange Date, such beneficial owner has not
delivered to Euro-clear or CEDEL S.A., as the case may be, a certificate in the
form set forth in Exhibit A to this Indenture dated no earlier than the
Certification Date, copies of which certificate shall be available from the
offices of Euro-clear and CEDEL S.A., the Trustee, any Authenticating Agent
appointed for such series of Securities and each Paying Agent and after the
Exchange Date, the interest of a beneficial owner of Securities of a series in a
temporary global Security shall be exchanged for definitive Securities (and
where the form of the definitive Securities is not specified by the Holder for
an interest in a permanent global Security) of the same series and of like tenor
following such beneficial owner's delivery to Euro-clear or CEDEL S.A., as the
case may be, of a certificate in the form set forth in Exhibit A to this
Indenture dated no earlier than the Certification Date. Unless otherwise
specified in such temporary global Security, any exchange shall be made free of
charge to the beneficial owners of such temporary global Security, except that a
Person receiving definitive Securities must bear the cost of insurance, postage,
transportation and the like in the event that such Person does not take delivery
of such definitive Securities in person at the offices of Euro-clear or CEDEL
S.A. Definitive Securities in bearer form to be delivered in exchange for any
portion of a temporary global Security shall be delivered only outside the
United States.

         Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 301, interest payable on a temporary global
Security on an Interest Payment Date for Securities of such series shall be


                                       21
<PAGE>   29


payable to Euro-clear and CEDEL S.A. on such Interest Payment Date upon delivery
by Euro-clear and CEDEL S.A. to the Trustee of a certificate or certificates in
the form set forth in Exhibit B to this Indenture, for credit without further
interest on or after such Interest Payment Date to the respective accounts of
the Persons who are the beneficial owners of such temporary global Security on
such Interest Payment Date and who have each delivered to Euro-clear or CEDEL
S.A., as the case may be, a certificate in the form set forth in Exhibit A to
this Indenture. Any interest so received by Euro-clear and CEDEL S.A. and not
paid as herein provided shall be returned to the Trustee immediately prior to
the expiration of two years after such Interest Payment Date in order to be
repaid to the Company in accordance with Section 1003.

         SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

         The Company shall cause to be kept at an office or agency to be
maintained by the Company in accordance with Section 1002 a register (being the
combined register of the Security Registrar and all transfer agents designated
pursuant to Section 1002 for the purpose of registration of transfer of
Securities and sometimes collectively referred to as the "Security Register") in
which, subject to such reasonable regulations as it may prescribe, the Company
shall provide for the registration of each series of Registered Securities and
the registration of transfers of such Registered Securities. The Trustee shall
serve initially as "Security Registrar" for the purpose of registering
Registered Securities and transfers of Registered Securities as herein provided.

         Upon surrender for registration of transfer of any Registered Security
of any series at the office or agency of the Company maintained pursuant to
Section 1002 for such purpose in a Place of Payment 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 of any authorized denominations and of a like tenor and
aggregate principal amount.

         At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series of any authorized
denominations and of a like tenor and aggregate principal amount, upon surrender
of the Securities to be exchanged at any such office or agency. Whenever any
Securities are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive. Unless otherwise provided with respect to
any series of Securities, Bearer Securities may not be issued in exchange for
Registered Securities.

         At the option of the Holder, Bearer Securities of any series may be
exchanged for Registered Securities of the same series of any authorized
denominations and of a like aggregate principal amount and tenor, upon surrender
of the Bearer Securities to be exchanged at any such office or agency, 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


                                       22
<PAGE>   30


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 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 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 located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such office or agency in exchange for a Registered
Security of the same 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 proposed date for payment of Defaulted Interest, such
Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and
interest or Defaulted Interest, as the case may be, will not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security
but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture.

         Whenever any Securities are so surrendered for exchange, 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 specified as
contemplated by Section 301, any permanent global Security shall be exchangeable
only as provided in this paragraph. If the beneficial owners of interests in a
permanent global Security are entitled to exchange such interests for Securities
of such series and of like tenor and principal amount of another authorized form
and denomination, as specified as contemplated by Section 301, then without
unnecessary delay but in any event not later than the earliest date on which
such interests may be so exchanged, the Company shall deliver to the Trustee
definitive Securities of that series in an aggregate principal amount equal to
the principal amount of such permanent global Security, executed by the Company.
On or after the earliest date on which such interests may be so exchanged, such
permanent global Security shall be surrendered from time to time in accordance
with instructions given to the Trustee and the Common Depositary (which
instructions shall be in writing but need not comply with Section 1501 or be
accompanied by an Opinion of Counsel) by the Common Depositary or such other
depositary as shall be specified in the Company Order with respect thereto to
the Trustee, as the Company's agent for such purpose, to be exchanged, in whole
or in part, for definitive Securities of the same series without charge, and the
Trustee shall authenticate and deliver,


                                       23
<PAGE>   31


in exchange for each portion of such permanent 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 permanent global Security
to be exchanged which, unless the Securities of the series are not issuable both
as Bearer Securities and as Registered Securities, as specified as contemplated
by Section 301, shall be in the form of Bearer Securities or Registered
Securities, or any combination thereof, as shall be specified by the beneficial
owner thereof; provided, however, that no such exchanges may occur during a
period beginning at the opening of business 15 days before any selection of
Securities of that series for redemption and ending on the relevant Redemption
Date; and provided, further, that no Bearer Security delivered in exchange for a
portion of a permanent global Security shall be mailed or otherwise delivered to
any location in the United States. Promptly following any such exchange in part,
such permanent global Security shall be returned by the Trustee to the Common
Depositary or such other depositary referred to above in accordance with the
instructions of the Company referred to above. If a Registered Security is
issued in exchange for any portion of such permanent global Security after the
close of business at the office or agency where such exchange occurs on (i) any
Regular Record Date and before the opening of business at such office or agency
on the relevant Interest Payment Date, or (ii) any Special Record Date and
before the opening of business at such office or agency on the related proposed
date for payment of Defaulted Interest, interest or Defaulted Interest, as the
case may be, will not be payable on such Interest Payment Date or proposed date
for payment, as the case may be, in respect of such Registered Security, but
will be payable on such Interest Payment Date or proposed date for payment, as
the case may be, only to the Person to whom interest in respect of such portion
of such permanent global Security is payable in accordance with provisions of
this Indenture.

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

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

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


                                       24
<PAGE>   32


         The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before any selection of Securities of that series for
redemption and ending at the close of business on (A) if Securities of the
series are issuable only as Registered Securities, the day of the mailing of the
relevant notice of redemption and (B) if Securities of the series are issuable
as Bearer Securities, the day of the first publication of the relevant notice of
redemption, or if Securities of the series are also issuable as Registered
Securities and there is no publication, the mailing of the relevant notice of
redemption, or (ii) to register the transfer of or exchange any Registered
Security so selected for redemption, in whole or in part, except the unredeemed
portion of any Registered Security being redeemed in part, or (iii) to exchange
any Bearer Security so selected for redemption except that such a Bearer
Security may be exchanged for a Registered Security of that series and like
tenor, provided that such Registered Security shall be simultaneously
surrendered for redemption.

         Notwithstanding the foregoing and except as otherwise specified as
contemplated by Section 301, any Book-Entry Security shall be exchangeable
pursuant to this Section 305 or Sections 304, 906 and 1107 for Securities
registered in the name of, and a transfer of a Book-Entry Security of any series
may be registered to, any Person other than the Depositary for such Security or
its nominee or a successor Depositary or its nominee only if (i) such Depositary
notifies the Company that it is unwilling or unable to continue as depositary
for such Book-Entry Security and a successor Depositary is not appointed by the
Company within ninety (90) days of such notice, or (ii) an Event of Default has
occurred with respect to such series and is continuing and the Security
Registrar has received a request from the applicable Depositary to issue
Securities in lieu of all or a portion of the Book-Entry Security (in which case
the Company shall deliver Securities within thirty (30) days of such request) or
(iii) the Company executes and delivers to the Trustee a Company Order that such
Book- Entry Security shall be so exchangeable and the transfer thereof so
registrable. Upon the occurrence in respect of any Book-Entry Security of any
series of any one or more of the conditions specified in clause (i) or (ii) of
the preceding sentence or such other conditions as may be specified, such
Book-Entry Security may be exchanged for Securities registered in the names of,
and the transfer of such Book-Entry Security may be registered to, such Persons
(including Persons other than the Depositary with respect to such series and its
nominees) as such Depositary shall direct. Notwithstanding any other provision
of this Indenture, any Security authenticated and delivered upon registration of
transfer of, or in exchange for, or in lieu of, any Book-Entry Security shall
also be a Book-Entry Security and shall bear the legend specified in Section 204
except for any Security authenticated and delivered in exchange for, or upon
registration of transfer of, a Book-Entry Security pursuant to the preceding
sentence.

         In connection with any transfer of a portion of the beneficial interest
in a Book-Entry Security to beneficial owners pursuant to this Section, the
Security Registrar shall reflect on its books and records the date and a
decrease in the principal amount of the Book-Entry Security in an amount equal
to the principal amount of the beneficial interest in the Book- Entry Security
to be transferred, and the Company shall execute, and the Trustee upon receipt


                                       25
<PAGE>   33


of a Company Order for the authentication and delivery of the Securities shall
authenticate and deliver, one or more Securities of the same series of like
tenor and amount.

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

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

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

         If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security 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 the Trustee
shall authenticate and deliver, in lieu of any such 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 and of like tenor and 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.

         In case any such 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 the principal of and any premium and interest on Bearer
Securities shall, except as otherwise provided in Section 1002, be payable only
at an office or agency located outside the United States.

         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 of any series with its coupons, if any, issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security or in
exchange for a Security to which


                                       26
<PAGE>   34


a destroyed, lost or stolen coupon appertains, shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security and its coupons, if any, or the destroyed, lost or
stolen coupon shall be at any time enforceable by anyone, and any such new
Security and coupons, if any, shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of that
series and their coupons, if any, duly issued hereunder.

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

         SECTION 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

         Unless otherwise provided as contemplated by Section 301 with respect
to any series of Securities, interest on any Registered Security which is
payable, and is punctually paid or duly provided for, on any Interest Payment
Date shall be paid to the Person in whose name that Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest. Unless otherwise so provided, at the option of
the Company, payment of interest on any Registered Security may be made (i) by
check mailed on or before the due date to the address of the Person entitled
thereto as such address shall appear in the Security Register or (ii) by wire
transfer to an account maintained by the Person entitled thereto as specified in
the Security Register; provided, that such Person shall have provided to the
Company or the Paying Agent wire transfer instructions at least five Business
Days prior to the applicable Interest Payment Date.

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

               (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Registered Securities of
         such series (or their respective Predecessor Securities) are registered
         at the close of business on a Special Record Date for the payment of
         such Defaulted Interest, which shall be fixed in the following manner.
         The Company shall notify the Trustee in writing of the amount of
         Defaulted Interest proposed to be paid on each Registered Security of
         such series, the date of the proposed payment and the Special Record
         Date, and at the same time the Company shall deposit with the Trustee
         an amount of money equal to the aggregate amount proposed to be paid in
         respect of such Defaulted Interest or shall make arrangements
         satisfactory to the Trustee for such deposit prior to the date of the
         proposed payment, such money when deposited to be held in trust for the
         benefit of the Persons entitled to such Defaulted Interest as in this
         Clause provided. The Special Record Date for the


                                       27
<PAGE>   35


         payment of such Defaulted Interest 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, in the name and at the expense of the
         Company, shall cause notice of the proposed payment of such Defaulted
         Interest and the Special Record Date therefor to be given to each
         Holder of Registered Securities of such series at the address of such
         Holder as it appears in the Security Register, not less than 10 days
         prior to such Special Record Date. Notice of the proposed payment of
         such Defaulted Interest and the Special Record Date therefor having
         been so mailed, such Defaulted Interest shall be paid to the Persons in
         whose names the Registered Securities of such series (or their
         respective Predecessor Securities) are registered at the close of
         business on such Special Record Date and shall no longer be payable
         pursuant to the following clause (2).

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

         Subject to the foregoing provisions of this Section 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 or the Trustee
may treat the Person in whose name such Registered Security is registered as the
owner of such Registered Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Sections 305 and 307) any
interest on such Security and for all other purposes whatsoever, whether or not
such Security be overdue, and neither the Company, the Trustee nor any agent of
the Company or the Trustee shall be affected by notice to the contrary.

         Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery. The Company, the Trustee and any agent of the Company or the
Trustee may treat the bearer of any Bearer Security and the bearer of any coupon
as the owner of such Security or coupon for the purpose of receiving payment
thereof or on account thereof and for all other purposes whatsoever, whether or
not such Security or coupon be overdue, and neither the Company, the Trustee nor
any agent of the Company or the Trustee shall be affected by notice to the
contrary.


                                       28
<PAGE>   36


         Notwithstanding the foregoing, with respect to any Book-Entry Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by a Depositary or impair, as between a
Depositary and holders of beneficial interests in any Book-Entry Security, the
operation of customary practices governing the exercise of the rights of the
Depositary (or its nominee) as Holder of such Book-Entry Security.

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

         SECTION 309. CANCELLATION.

         All Securities and coupons surrendered for payment, redemption,
registration of transfer or exchange or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee. All Registered Securities and matured coupons so delivered shall
be promptly canceled by the Trustee. All Bearer Securities and unmatured coupons
so delivered shall be held by the Trustee and, upon instruction by a Company
Order, shall be canceled or held for reissuance. Bearer Securities and unmatured
coupons held for reissuance may be reissued only in replacement of mutilated,
lost, stolen or destroyed Bearer Securities of the same series and like tenor or
the related coupons pursuant to Section 306. All Bearer Securities and unmatured
coupons held by the Trustee pending such cancellation or reissuance shall be
deemed to be delivered for all purposes of this Indenture and the Securities.
The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and may deliver to the Trustee (or
to any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall be promptly canceled by the Trustee. No

canceled as provided in this Section, except as expressly permitted by this
Indenture. All canceled Securities and coupons held by the Trustee shall be
disposed of in accordance with its customary practice.

         SECTION 310.  COMPUTATION OF INTEREST.

         Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

         SECTION 311.  CUSIP NUMBERS.

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

(except as to any surviving rights of registration of transfer or exchange of
Securities herein expressly provided for, and any right to receive additional
amounts, as provided in Section 1004), and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when (1) either

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

to the Trustee for cancellation; or

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

                                       30

                    (i) have become due and payable, or

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

                    (iii) are to be called for redemption within one year under
               arrangements satisfactory to the Trustee for the giving of notice
               of redemption by the Trustee in the name, and at the expense, of
               the Company; and 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 the purpose an amount sufficient to
               pay and discharge the entire indebtedness on such Securities and
               coupons not theretofore delivered to the Trustee for
               cancellation, for principal (and premium, if any) and any
               interest to the date of such deposit (in the case of Securities
               which have become due and payable) or to the Stated Maturity or
               Redemption Date, as the case may be;

                  (2) the Company has paid or caused to be paid all other sums
         then due and payable hereunder by the Company; and

                  (3) the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel, which, when taken together,
         state that all conditions precedent herein provided for relating to the
         satisfaction and discharge of this Indenture have been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 606, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to clause (1)(B) of this Section,
the obligations of the Trustee under Section 402 and the last paragraph of
Section 1003 shall survive.

         SECTION 402.  APPLICATION OF TRUST MONEY.

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 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 and any
premium and interest for whose payment such money has been deposited with the
Trustee.

         SECTION 501.  EVENTS OF DEFAULT.

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

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

                  (2) default in the payment of any interest upon any Security

         and as due by the terms of a Security of that series and continuance of
         such default for a period of 30 days; or

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

                  (5) the entry of a decree or order by a court having
         jurisdiction in the premises (A) for relief in respect of the Company
         in an involuntary case or proceeding under the Federal Bankruptcy Code
         or any other applicable federal or state bankruptcy, insolvency,
         reorganization or other similar law or (B) adjudging the Company
         bankrupt or insolvent, or approving a petition seeking reorganization,
         arrangement, adjustment or composition of the Company under the Federal
         Bankruptcy Code or any applicable federal or state law, or appointing
         under any such law a custodian, receiver, liquidator, assignee,
         trustee, sequestrator or other similar official of the Company or of a

         substantial part of its consolidated assets, or ordering the winding up
         or liquidation of its affairs, and the continuance of any such decree
         or order for relief or any such other decree or order unstayed and in
         effect for a period of 60 consecutive days; or

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

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


         SECTION 502.  ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the Trustee
or the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount (or, if any of the
Securities of that series are Original Issue Discount Securities or Indexed
Securities, such portion of the principal amount of such Securities as may be
specified in the terms thereof) of all of the Securities of that series to be
due and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by Holders), and upon any such declaration such principal
amount (or specified amount) shall become immediately due and payable.

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


                                       33
<PAGE>   41


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

                           (A) all overdue interest on all Outstanding
         Securities of that series,

                           (B) all unpaid principal of (and premium, if any, on)
         any Outstanding Securities of that series which have become due
         otherwise than by such declaration of acceleration and any interest
         thereon at the rate or rates prescribed therefor in such Securities,

                           (C) to the extent that payment of such interest is
         lawful and is required hereunder, interest upon overdue interest at the
         rate or rates prescribed therefor in such Securities (without
         duplication of any amount paid or deposited pursuant to clauses (A) and
         (B) above), 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

                  (2) all Events of Default with respect to Securities of that
         series, other than the non-payment of the principal of (or premium, if
         any, on) or interest on Securities of that series which have become due
         solely by such declaration of acceleration, 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) default is made in the payment of any interest on any
         Security when such interest becomes due and payable and such default
         continues for a period of 30 days, or

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

         the Company will, upon demand of the Trustee, pay to it, for the
benefit of the Holders of such Securities and coupons, the whole amount then due
and payable on such Securities and coupons for principal and any premium and
interest and, to the extent that payment of such interest shall be legally
enforceable, interest on any overdue principal and premium and on


                                       34
<PAGE>   42

any overdue interest, at the rate or rates prescribed therefor in such
Securities and, in addition thereto, such further amount as shall be sufficient
to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

         If 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 related coupons by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such rights, whether for
the specific enforcement of any covenant or agreement in this Indenture or in
aid of the exercise of any power granted herein, or to enforce any other proper
remedy.

         SECTION 504.  TRUSTEE MAY FILE PROOFS OF CLAIM.

         In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 606.

         No provision of this Indenture shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may, on behalf of Holders, vote for the election of a
trustee of bankruptcy or similar official and be a member of a creditors' or
other similar committee.


                                       35
<PAGE>   43

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

         All rights of action and claims under this Indenture or 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 trust, and any recovery of
judgment shall, after provision for the payment of reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the Holders of the Securities and coupons 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
or interest, 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 under
Section 606;

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

                  third:  Any remaining amounts shall be repaid to the Company.

         In any case in which Securities are Outstanding that are denominated in
more than one currency and the Trustee is directed to make ratable payments
under this Section to Holders of such Securities, unless otherwise provided with
respect to any series of Securities, the Trustee shall calculate the amount of
such payments as follows: (i) as of the day the Trustee collects an amount under
this Article, the Trustee shall, as to each Holder of a Security to whom an
amount is due and payable under this Section that is denominated in a foreign
currency, determine that amount in Dollars that would be obtained for the amount
owing such Holder, using the rate of exchange at which in accordance with normal
banking procedures the Trustee could purchase in The City of New York Dollars
with such amount owing; (ii) calculate the sum of all Dollar amounts determined
under (i) and add thereto any amounts due and payable in Dollars; and (iii)
using the individual amounts determined in (i) or any individual amounts due and
payable in Dollars, as the case may be, as a numerator, and the sum calculated
in (ii) as a denominator, calculate as to each Holder of a Security to whom an


                                       36
<PAGE>   44

amount is owed under this Section the fraction of the amount collected under
this Article payable to such Holder. Any expenses incurred by the Trustee in
actually converting amounts owing Holders of Securities denominated in a
currency other than that in which any amount is collected under this Article
shall be likewise (in accordance with this paragraph) borne ratably by all
Holders of Securities to whom amounts are payable under this Section. Any
calculations done by the Trustee shall be presumptively conclusive and binding
absent manifest error.

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

         SECTION 507.  LIMITATION ON SUITS.

         No Holder of any Security of any series or any related coupons 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 that series;

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

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

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


                                       37
<PAGE>   45

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

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

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

         Notwithstanding any other provision in this Indenture, the Holder of
any Security or coupon shall have the right, which is absolute and
unconditional, to receive payment of the principal of and any premium and
(subject to Sections 305 and 307) any interest on such Security or payment of
such coupon on the respective Stated Maturities expressed in such Security or
coupon (or, in the case of redemption, on the Redemption Date) and to institute
suit for the enforcement of any such payment, and such rights shall not be
impaired without the consent of such Holder.

         SECTION 509.  RESTORATION OF RIGHTS AND REMEDIES.

         If the Trustee or any Holder of a Security or 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, subject to any determination in such proceeding, the Company, the Trustee
and the Holders of Securities and coupons shall be restored severally and
respectively to their former positions hereunder and thereafter all rights and
remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

         SECTION 510.  RIGHTS AND REMEDIES CUMULATIVE.

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


                                       38
<PAGE>   46

         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 the Holders of Securities or coupons may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders of Securities or coupons, as the case may be.

         SECTION 512.  CONTROL BY HOLDERS.

         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, provided that

                  (1) such direction shall not be in conflict with any rule of
         law or with this Indenture or involve the Trustee in personal liability
         or be unjustly prejudicial to the Holders of Securities of such series
         not taking part in such direction,

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

                  (3) the Trustee need not take any action which might involve
         it in personal liability or be unduly prejudicial to the Holders not
         joining therein.

         SECTION 513.  WAIVER OF PAST DEFAULTS.

         The Holders of not less than a majority in aggregate principal amount
of the Outstanding Securities of any series may on behalf of the Holders of all
the Securities of such series waive any past or existing Default or Event of
Default hereunder with respect to the Securities of such series and its
consequences, except a Default or Event of Default,

                  (1) in respect of the payment of the principal of (or premium,
         if any, on) or interest on any Security of such series, 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.

Upon any such waiver, such Default or Event of Default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured, for
every purpose of this


                                       39
<PAGE>   47

Indenture; but no such waiver shall extend to any subsequent or other Default or
Event of Default or impair any right consequent thereon. Any such waiver may
(but need not) be given in connection with a tender offer or exchange offer for
the Securities of the series affected.

         SECTION 514.  UNDERTAKING FOR COSTS.

         In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided, however, that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Company.

         SECTION 515.  WAIVER OF STAY OR EXTENSION LAWS.

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

                                   ARTICLE SIX
                                   THE TRUSTEE

         SECTION 601.  DUTIES OF TRUSTEE.

                  (a) If an Event of Default has occurred and is continuing with
respect to Securities of any series, the Trustee shall exercise the rights and
powers vested in it by this Indenture and use the same degree of care and skill
in their exercise as a prudent person would exercise or use under the
circumstances in the conduct of his own affairs.

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


                           (i) the Trustee undertakes to perform such duties and
         only such duties as are specifically set forth in this Indenture and no
         implied covenants or obligations shall be read into this Indenture
         against the Trustee; and



                                       40
<PAGE>   48

                           (ii) in the absence of bad faith on its part, the
         Trustee may conclusively rely, and shall be fully protected in so
         relying, as to the truth of the statements and the correctness of the
         opinions expressed therein, upon certificates or opinions furnished to
         the Trustee and conforming to the requirements of this Indenture;
         provided, however, the Trustee shall examine the certificates and
         opinions to determine whether or not they conform to the requirements
         of this Indenture.

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

                           (i) this paragraph shall not limit the effect of
         Section 601(b);

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

                           (iii) the Trustee shall not be liable with respect to
         any action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 512.

SECTION 602.  CERTAIN RIGHTS OF TRUSTEE.

         Subject to the provisions of Section 601:

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

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

                  (3) whenever in the administration of this Indenture the
         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, rely conclusively upon an
         Officers' Certificate;

                  (4) the Trustee may consult with counsel reasonably selected
         by it and the written advice of such counsel or any Opinion of Counsel
         shall be full and complete


                                       41
<PAGE>   49

         authorization and protection in respect of any action taken, suffered
         or omitted by it hereunder in good faith and in reliance thereon;

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

                  (6) the Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, direction,
         consent, order, bond, debenture, note, other evidence of indebtedness
         or other paper or document, but the Trustee, in its discretion, may
         make such further inquiry or investigation into such facts or matters
         as it may reasonably see fit, and, if the Trustee shall determine to
         make such further inquiry or investigation, it shall be entitled to
         examine the books, records and premises of the Company, personally or
         by agent or attorney;

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

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

                  (9) the Trustee shall not be deemed to have notice or
         knowledge of any matter unless a Responsible Officer has actual
         knowledge thereof or unless written notice thereof is received by the
         Trustee at its Corporate Trust Office and such notice references the
         Securities generally, the Company or this Indenture.

         The Trustee shall not be required to advance, expend or risk its own
funds or otherwise incur any financial liability in the performance of any of
its duties hereunder, or in the exercise of any of its rights or powers if it
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it.

         SECTION 603. TRUSTEE NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF
SECURITIES.

         The recitals contained herein and in the Securities (except the
Trustee's certificates of authentication) and in any coupons shall be taken as
the statements of the Company, and


                                       42
<PAGE>   50

neither the Trustee nor any Authenticating Agent assumes any responsibility for
their correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities or coupons, except that the
Trustee represents that it is duly authorized to execute and deliver this
Indenture, authenticate the Securities and perform its obligations hereunder.
Neither the Trustee nor any Authenticating Agent shall be accountable for the
use or application by the Company of any Securities or the proceeds thereof.

         SECTION 604.  MAY HOLD SECURITIES.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company or of the Trustee, in its individual
or any other capacity, may become the owner or pledgee of Securities and coupons
and, subject to TIA Sections 310(b) and 311 in the case of the Trustee, may
otherwise deal with the Company with the same rights it would have if it were
not the Trustee, Authenticating Agent, Paying Agent, Security Registrar or such
other agent.

         SECTION 605.  MONEY HELD IN TRUST.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise agreed with the Company. So long as no Event of Default shall have
occurred and be continuing, all interest allowed on any such money shall be paid
from time to time upon receipt by the Trustee of a Company Order except as
otherwise provided in this Indenture.

         SECTION 606.  COMPENSATION AND REIMBURSEMENT.

         The Company agrees

                  (1) to pay to the Trustee from time to time, and the Trustee
         shall be entitled to, such compensation as shall be agreed to in
         writing by the Company and the Trustee for all services rendered by it
         hereunder (which compensation shall not be limited by any provision of
         law in regard to the compensation of a trustee of 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 willful misconduct, negligence
         or bad faith; and


                                       43
<PAGE>   51

                  (3) to indemnify the Trustee for, and to hold it harmless
         against, any and all loss, liability, or expense incurred without
         willful misconduct, negligence or bad faith on its part, (i) arising
         out of or in connection with the acceptance or administration of this
         trust, including the costs and expenses of defending itself against any
         claim or liability in connection with the exercise or performance of
         any of its powers or duties hereunder or (ii) in connection with
         enforcing this indemnification provision.

         The obligations of the Company under this Section to compensate the
Trustee, to pay or reimburse the Trustee for expenses, disbursements and
advances and to indemnify and hold harmless the Trustee shall constitute
additional indebtedness hereunder and shall survive the satisfaction and
discharge of this Indenture.

         When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 501(5) or Section 501(6), such expenses
and the compensation for the services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or
other similar law.

         SECTION 607.  CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

         There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series. Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such, has a combined
capital and surplus of at least $50,000,000, subject to supervision or
examination by Federal or State authority. If such corporation publishes reports
of condition at least annually, pursuant to law or to the requirements of
federal, state, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section and to the extent permitted by
the Trust Indenture Act, the combined capital and surplus of such Person shall
be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Trustee with respect to the
Securities of any series shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

         SECTION 608.  DISQUALIFICATION; CONFLICTING INTERESTS.

         If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by the Trust Indenture Act, the Trustee shall not be deemed to have a
conflicting interest by virtue of being a trustee under this (1) Indenture with
respect to Securities of more than one series and (2) any other indenture or
indentures under which other securities or certificates of interest or
participation in other securities of the Company are outstanding.

<PAGE>   52

         SECTION 609.  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 610.

         (b) The Trustee may resign at any time by giving written notice thereof
to the Company. If the instrument of acceptance by a successor Trustee required
by Section 610 hereof shall not have been delivered to the Trustee within 30
days after the giving of such notice of resignation, the resigning Trustee may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

         (c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of not less than a majority in
aggregate principal amount of the Outstanding Securities of such series
delivered to the Trustee and to the Company.

         (d)      If at any time:

                  (1) the Trustee shall fail to comply with the provisions of
         TIA Section 310(b) after written request therefor by the Company or by
         any Holder who has been a bona fide Holder of a Security for at least
         six months, or

                  (2) the Trustee shall cease to be eligible under Section 607
         and shall fail to resign after written request therefor by the Company
         or by any Holder who has been a bona fide Holder of a Security for at
         least six months, or

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

         then, in any such case,

                           (A) the Company by a Board Resolution may remove the
                  Trustee with respect to all Securities, or

                           (B) subject to TIA Section 315(e), any Holder who has
                  been a bona fide Holder of a Security for at least six months
                  may, on behalf of himself and all others similarly situated,
                  petition any court of competent jurisdiction for the removal
                  of the Trustee with respect to all Securities and the
                  appointment of a successor Trustee or Trustees.


                                      45
<PAGE>   53

         (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of the Trustee for any cause,
with respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series) and shall comply with the
applicable requirements of Section 610. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in aggregate principal amount of
the Outstanding Securities of such series delivered to the Company and the
retiring Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment in accordance with the applicable requirements of
Section 610, become the successor Trustee with respect to the Securities of such
series and to that extent supersede the successor Trustee appointed by the
Company. If no successor Trustee with respect to the Securities of any series
shall have been so appointed by the Company or the Holders and accepted
appointment in the manner required by Section 610, any Holder who has been a
bona fide Holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series. The evidence of such successorship may, but
need not be, evidenced by a supplemental indenture.

         (f) The Company shall give notice of each resignation and each removal
of the Trustee to the Holders of Securities of any series and each appointment
of a successor Trustee with respect to the Securities of any series in the
manner provided for in Section 1505. Each notice shall include the name of the
successor Trustee with respect to the Securities of such series and the address
of its Corporate Trust Office.

         SECTION 610.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee but on the request of
the Company or the successor Trustee, such retiring Trustee shall, upon payment
of all amounts due it under Section 606, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder.

         (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each


                                       46
<PAGE>   54

successor Trustee with respect to the Securities of one or more series shall
execute and deliver an indenture supplemental hereto wherein each successor
Trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each 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 and 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 upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with 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; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

         (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section, as the case may be.

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

         SECTION 611. 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,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. As soon as practicable, the successor Trustee
shall give notice to the Company of its succession. In case any Securities shall
have been authenticated, but not


                                       47
<PAGE>   55

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; and in case at that
time any of the Securities shall not have been authenticated, any successor
Trustee may authenticate such Securities either in the name of any predecessor
hereunder or in the name of the successor Trustee; and in all such cases such
certificates shall have the full force which it is anywhere in the Securities of
like tenor or in this Indenture provided; provided, however, that the right to
adopt the certificate of authentication of any predecessor Trustee or to
authenticate Securities in the name of any predecessor Trustee shall apply only
to its successor or successors by merger, conversion or consolidation.

         SECTION 612.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

         If and when the Trustee shall be or become a creditor of the Company
(or any other obligor under the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

         SECTION 613.  NOTICE OF DEFAULTS.

         Within 60 days after the occurrence of any Default with respect to any
series of Securities issued hereunder, the Trustee shall transmit in the manner
and to the extent provided in TIA Section 313(c), notice of such Default
hereunder known to the Trustee, unless such Default shall have been cured or
waived; provided, however, that, except in the case of a Default in the payment
of the principal of (or premium, if any, on) or interest on any series of
Securities, the Trustee shall be protected in withholding such notice if and so
long as the board of directors, the executive committee or a trust committee of
directors and/or Responsible Officers of the Trustee in good faith determines
that the withholding of such notice is in the interest of the Holders of such
series.

         SECTION 614.  APPOINTMENT OF AUTHENTICATING AGENT.

         The Trustee, with the prior written consent of the Company and after
giving notice of the appointment described in this Section 614 in the manner
provided in Section 1505 to all Holders or Registered Securities, if any,
affected by such appointment, may appoint an Authenticating Agent or Agents with
respect to one or more series of Securities which shall be authorized to act on
behalf of the Trustee to authenticate Securities of such series issued upon
original issue and upon exchange, registration of transfer or partial redemption
thereof 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


                                       48

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 shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia (or, if Bearer Securities, organized and doing
business under the laws of the country in which the Bearer Securities are
eligible), authorized under such laws to act as Authenticating Agent, having a
combined capital and surplus of not less than $50,000,000 and subject to
supervision or examination by Federal or State authority (or, if Bearer
Securities, an authority of the country in which the Bearer Securities are
eligible). If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent 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 such Authenticating Agent,
shall continue to be an Authenticating Agent, 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 such Authenticating
Agent.

         An Authenticating Agent may, and if it shall cease to be eligible
shall, resign at any time by giving written notice thereof to the Trustee and to
the Company. The Trustee may at any time terminate the agency of an
Authenticating Agent by giving written notice thereof to such Authenticating
Agent and to the Company. Upon receiving such a notice of resignation or upon
such a termination, or in case at any time such Authenticating Agent shall cease
to be eligible in accordance with the provisions of this Section, the Trustee
may appoint a successor Authenticating Agent which shall be acceptable to the
Company and shall give notice of such appointment in the manner provided in
Section 1505 to all Holders of Registered Securities, if any, of the series with
respect to which such Authenticating Agent will serve. 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 to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

         If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

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

                                              ---------------------------------
                                              As Authenticating Agent

                                         By:
                                              ---------------------------------
                                              Authorized Signatory"

         If all the Securities of a series may not be originally issued at one
time, and if the Company has an Affiliate eligible to be appointed as an
Authenticating Agent hereunder or the Trustee does not have an office capable of
authenticating Securities upon original issuance located in a Place of Payment
where the Company wishes to have Securities of such series authenticated upon
original issuance, the Trustee, if so requested by the Company in writing (which
writing need not comply with Section 1501 and need not be accompanied by an
Opinion of Counsel), shall appoint in accordance with this Section an
Authenticating Agent (which, if so requested by the Company, shall be such
Affiliate of the Company) having an office in a Place of Payment designated by
the Company with respect to such series of Securities.

same, agrees with the Company, the Security Registrar and the Trustee that none
of the Company, the Security Registrar or the Trustee, or any agent of any of
them, shall be held accountable by reason of the disclosure of any information
as to the names and addresses of the Holders in accordance with TIA Section 312,
regardless of the source from which such information was derived, that each of
such Persons shall have the protection of TIA Section 312(c) and that the
Trustee shall not be held accountable by reason of mailing any material pursuant
to a request made under TIA Section 312(b).

         The Company shall promptly notify the Trustee in writing if the
Securities become listed on any stock exchange or automatic quotation system.

         Commencing at the time this Indenture is qualified under the Trust
Indenture Act, a copy of each Trustee's report, at the time of its mailing to
Holders of Securities, shall be mailed to the Company and filed with the
Commission and each stock exchange, if any, on which the Securities are listed.

case, expressly assume by a supplemental indenture to this Indenture executed

case, this Indenture shall remain in full force and effect;

         (b) immediately after giving effect to such transaction or series of

         benefit of such series), to provide any additional rights or benefits
         to such Holders, or to surrender any right or power herein conferred
         upon the Company; or


                                       53
<PAGE>   61

                  (3) to add any additional Events of Default for the benefit of

         matters or questions arising under this Indenture; provided, however,
         that such action shall not adversely affect the interests of the
         Holders of Securities of any series or any related coupons in any
         material respect; or

                  (6) to secure the Securities pursuant to the requirements of
         this Indenture or otherwise; or

                  (7) to add to or change any of the provisions of this
         Indenture to provide that Bearer Securities may be registrable as to

         that any such addition, change or elimination (A) shall neither (i)
         apply to any Security of any series created prior to the execution of
         such supplemental indenture and entitled to the benefit of such
         provision nor (ii) modify the rights of the Holder of any such Security
         with respect to such provision or (B) shall become effective only when
         there is no such Security Outstanding; or

the Trustee of the documents described in Section 903 hereof, the Trustee shall
join with the Company in the execution of any supplemental indenture authorized
or permitted by the terms of this Indenture and to make any further appropriate
agreements and stipulations which may be therein contained.

         SECTION 902.  SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

         With the consent of the Holders of not less than a majority in
aggregate principal amount of the Outstanding Securities of each series affected
by such supplemental indenture (which consent may, but need not, be given in
connection with any tender offer or exchange offer for the Securities of each
series affected), by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by a Board Resolution, and the Trustee
upon Company request may enter into an indenture or indentures supplemental
hereto, amendments to this Indenture or waivers for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or of modifying in any manner the rights of the Holders of
Securities of such series and any related coupons under this Indenture;
provided, however, that no such supplemental indenture, amendment or waiver
shall, without the consent of the Holder of each Outstanding Security affected
thereby:

                  (1) change the Stated Maturity of the principal of, or any
         installment of principal of or interest on, any Security, or reduce the
         principal amount thereof or the rate of interest thereon or any premium
         payable upon the redemption thereof, or reduce the amount of the
         principal of an Original Issue Discount Security or any other Security
         which would be due and payable upon a declaration of acceleration of
         the Maturity thereof pursuant to Section 502, or adversely affect any
         right of repayment at the option of a Holder of any Security, or reduce
         the amount of, or postpone the date fixed for, the payment of any
         sinking fund or analogous obligation, or change any Place of Payment
         where, or the coin or currency in which, any Security or any premium or
         interest thereon is payable, or impair the right to institute suit for
         the enforcement of any such payment on or after the Stated Maturity
         thereof (or, in the case of redemption, on or after the Redemption
         Date), or


                                       55
<PAGE>   63

                  (2) reduce the percentage in principal amount of the
         Outstanding Securities of any series, the consent of whose Holders is
         required for any such supplemental indenture, or the consent of whose
         Holders is required for any waiver (of compliance with certain
         provisions of this Indenture or certain defaults hereunder and their
         consequences) provided for in this Indenture, or

                  (3) change any obligation of the Company to maintain an office
         or agency in the places and for the purposes specified in Section 1002,
         or

         or Section 1007 except to increase any such percentage or to provide
         that certain other provisions of this Indenture cannot be modified or
         waived without the consent of the Holder of each Outstanding Security
         affected thereby; provided, however, that this clause shall not be
         deemed to require the consent of any Holder of a Security or coupon
         with respect to changes in the references to "the Trustee" and
         concomitant changes in this Section and Section 1007 or the deletion of
         this proviso, in accordance with the requirements of Sections 610 and
         901(4).

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

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

         SECTION 903.  EXECUTION OF SUPPLEMENTAL INDENTURES.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive
and (subject to Section 601) shall be fully protected in relying upon an Opinion
of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

         SECTION 904.  EFFECT OF SUPPLEMENTAL INDENTURES.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
and of any coupons appertaining thereto shall be bound thereby.

         SECTION 905.  CONFORMITY WITH TRUST INDENTURE ACT.

         Every supplemental indenture or amendment executed pursuant to this
Article shall conform to the requirements of the Trust Indenture Act as then in

         SECTION 906.  REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

         Securities of any series authenticated and delivered after the
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
to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series and of like tenor.

                                   ARTICLE TEN
                                    COVENANTS

         SECTION 1001.  PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

         The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the Securities of that series in accordance with the terms of
the Securities, any coupons appertaining thereto and this Indenture. Unless
otherwise specified as contemplated by Section 301 with respect to any series of
Securities, any interest due on Bearer Securities on or before Maturity shall be
payable only upon presentation and surrender of the several coupons for such
interest installments as are evidenced thereby as they severally mature.

         SECTION 1002.  MAINTENANCE OF OFFICE OR AGENCY.

        If Securities of a series are issuable only as Registered Securities,
the Company will maintain in each Place of Payment for such series an office or
agency where Securities of that series may be presented or surrendered for
payment, where Securities of that series may be surrendered for registration of
transfer or exchange and where notices and demands to or upon


                                       57
<PAGE>   65

the Company in respect of the Securities of that series and this Indenture may
be served. If Securities of a series are issuable as Bearer Securities, the
Company will maintain (A) in The City of New York, an office or agency where any
Registered Securities of that series may be presented or surrendered for
payment, where any Registered Securities of that series may be surrendered for
registration of transfer, where Securities of that series may be surrendered for
exchange, where notices and demands to or upon the Company in respect of the
Securities of that series and this Indenture may be served and where Bearer
Securities of that series and related coupons may be presented or surrendered
for payment in the circumstances described in the following paragraph (and not
otherwise), (B) subject to any laws or regulations applicable thereto, in a
Place of Payment for that series which is located outside the United States, an
office or agency where Securities of that series and related coupons may be
presented and surrendered for payment (including payment of any additional
amounts payable on Securities of that series pursuant to Section 1004);
provided, however, that if the Securities of that series are listed on The
International Stock Exchange of the United Kingdom and the Republic of Ireland
Limited, the Luxembourg Stock Exchange or any other stock exchange located
outside the United States and such stock exchange shall so require, the Company
will maintain a Paying Agent for the Securities of that series in London,
Luxembourg or any other required city located outside the United States, as the
case may be, so long as the Securities of that series are listed on such
exchange, and (C) subject to any laws or regulations applicable thereto, in a
Place of Payment for that series located outside the United States an office or
agency where any Registered Securities of that series may be surrendered for
registration of transfer, where Securities of that series may be surrendered for
exchange and where notices and demands to or upon the Company in respect of the
Securities of that series and this Indenture may be served. The Company will
give prompt written notice to the Trustee and prompt notices to the Holders as
provided in Section 1505 of the location, and any change in the location, of any
such office or agency. If at any time the Company shall fail to maintain any
such required office or agency in respect of any series of Securities or shall
fail to furnish the Trustee with the address thereof, such presentations and
surrenders of Securities of that series may be made and notices and demands may
be made or served at the Corporate Trust Office of the Trustee, except that
Bearer Securities of that series and the related coupons may be presented and
surrendered for payment (including payment of any additional amounts payable on
Bearer Securities of that series pursuant to Section 1004) at any Paying Agent
for such series located outside the United States, and the Company hereby
appoints the same as its agents to receive such respective presentations,
surrenders, notices and demands.

         No payment of principal, premium or interest on Bearer Securities shall
be made at any office or agency of the Company 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, that, if
the Securities of a series are denominated and payable in Dollars payment of
principal of and any premium and interest on any Bearer Security (including any
additional amounts payable on Securities of such series pursuant to Section
1004) shall be made at the office of the Company's Paying Agent in The City of
New York, if (but only if) payment in Dollars of the full amount of such
principal, premium, interest or additional


                                       58
<PAGE>   66

amounts, as the case may be, at all offices or agencies outside the United
States maintained for the 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 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 so maintain an office or
agency in accordance with the requirements set forth above for Securities of any
series for such purposes. The Company will give prompt written notice to the
Trustee and the Holders of any such designation or rescission and of any other
change in the location of any such other office or agency.

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

     If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it shall, on or before 11:00 a.m., Eastern time, on
each due date of the principal of (or premium, if any, on) or interest on any of
the Securities of that series, segregate and hold in trust for the benefit of
the Persons entitled thereto a sum sufficient to pay the principal (and premium,
if any) and interest so becoming due until such sum shall be paid to such
Persons or otherwise disposed of as herein provided and will promptly notify the
Trustee of its action or failure so to act.

     Whenever the Company shall have one or more Paying Agents for any series of
Securities, it will, on or before 11:00 a.m., Eastern time, on each due date of
the principal of (or premium, if any, on) or interest on any Securities of that
series, deposit with a Paying Agent immediately available funds in a sum
sufficient to pay such amount, such sum to be held as provided by the Trust
Indenture Act, 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 or itself) to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will: (1) hold all sums
held by it for the payment of the principal of (and premium, if any, on) or
interest on Securities of that series in trust for the benefit of the Persons
entitled thereto until such sums shall be paid to such Persons or otherwise
disposed of as herein provided; (2) give the Trustee notice of any default by
the Company (or any other obligor upon the Securities of that series) in the
making of any payment of principal (and premium, if any) or interest; 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 held in trust by such Paying
Agent for payment in respect of the Securities of that series.


                                       59
<PAGE>   67

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

     The Trustee and each Paying Agent shall promptly pay to the Company upon
Company Request any money held by them at any time in excess of amounts required
to pay principal of, premium, if any, or interest on the Securities of any
series.

     Subject to applicable escheat and abandoned property laws, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of (and premium, if any, on) or interest
on any Security of any series and remaining unclaimed for one year after such
principal (and premium, if any) or interest has 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, 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, any unclaimed balance of such money then remaining
will be repaid to the Company.

     SECTION 1004. ADDITIONAL AMOUNTS.

     If the Securities of a series provide for the payment of additional
amounts, the Company will pay to the Holder of any Security of such series or
any coupon appertaining thereto additional amounts as provided therein. Whenever
in this Indenture there is mentioned, in any context, the payment of the
principal of or any premium or interest on, or in respect of, any Security of
any series or payment of any related 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 for in this
Section to the extent that, in such context, additional amounts are, were or
would be payable in respect thereof pursuant to the provisions of this Section
and express mention of the payment of additional amounts (if applicable) in any
provisions hereof shall not be construed as excluding additional amounts in
those provisions hereof where such express mention is not made. If the
Securities of a series provide for the payment of additional amounts, at least
10 days prior to the first Interest Payment Date with respect to that series of
Securities (or if the Securities of that series will



                                       60
<PAGE>   68

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

     SECTION 1005. PURCHASE OF SECURITIES BY COMPANY OR SUBSIDIARY.

     If and so long as the Securities of a series are listed on The
International Stock Exchange of the United Kingdom and the Republic of Ireland
Limited and such stock exchange shall so require, the Company will not, and will
not permit any of its Subsidiaries to, purchase any Securities of that series by
private treaty at a price (exclusive of expenses and accrued interest) which
exceeds 120% of the mean of the nominal quotations of the Securities of that
series as shown in The Stock Exchange Daily Official List for the last trading
day preceding the date of purchase.

     SECTION 1006. STATEMENT BY OFFICER AS TO DEFAULT.

     The Company shall deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers thereof
the Company is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and, if the Company shall be
in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge.

     SECTION 1007. WAIVER OF CERTAIN COVENANTS.

     Except as otherwise specified as contemplated by Section 301 for Securities
of such series or as otherwise required by law, the Company may, with respect to
the Securities of any series, omit in any particular instance to comply with any
term, provision or condition set




                                       61
<PAGE>   69

forth in any covenant provided pursuant to Section 301(19), 901(2) or 901(11)
for the benefit of the Holders of such series, if before the time for such
compliance the Holders of at least a majority in aggregate principal amount of
the Outstanding Securities of such series shall, by Act of such Holders and on
behalf of the Holders of all Securities of such series, either waive such
compliance in such instance or generally waive 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.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

                     SECTION 1101. APPLICABILITY OF ARTICLE.

     Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 301 for such Securities) in accordance with
this Article.

     SECTION 1102. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

     The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution, Officers' Certificate or in another manner specified as
contemplated by Section 301 for such Securities. In the case of any redemption
at the election of the Company of less than all the Securities of any series
(including any such redemption affecting only a single Security), the Company
shall, at least 45 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, of the principal amount of Securities of such
series to be redeemed and, if applicable, of the tenor of the Securities of such
series to be redeemed. In the case of any redemption of Securities (i) prior to
the expiration of any restriction on such redemption provided in the terms of
such Securities or elsewhere in this Indenture, or (ii) pursuant to an election
of the Company which is subject to a condition specified in the terms of such
Securities, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction or condition.

     SECTION 1103. SELECTION OF SECURITIES TO BE REDEEMED.

     If less than all the Securities of any series are to be redeemed
(unless all the Securities of such series and of a specified tenor are to be
redeemed or unless such redemption affects only a single Security) the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Company or the Trustee, from the Outstanding
Securities of such series not previously called for redemption, by such method
as the Company or the Trustee shall deem fair and appropriate and which may
provide for the




                                       62

<PAGE>   70

selection for redemption of portions (equal to the minimum authorized
denomination for Securities of that series or any integral multiple thereof) of
the principal amount of Registered Securities of such series of a denomination
larger than the minimum authorized denomination for Securities of that series or
of the principal amount of global Securities of such series. If less than all of
the Securities of such series and of a specified tenor are to be redeemed
(unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Company or the Trustee, from the Outstanding Securities
of such series and specified tenor not previously called for redemption in
accordance with the preceding sentence.

     The Company or the Trustee, as the case may be, shall promptly notify the
other in writing of the Securities selected for redemption as aforesaid and, in
the case of any Securities selected for partial redemption as aforesaid, the
principal amount thereof to be redeemed. For all purposes of this Indenture,
unless the context otherwise requires, all provisions relating to the redemption
of Securities shall relate, in the case of any Securities redeemed or to be
redeemed only in part, to the portion of the principal amount 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 1505
to the Holders of Securities to be redeemed not less than 30 nor more than 60
days prior to the Redemption Date.

     All notices of redemption shall state:

          (1) the Redemption Date,

          (2) the Redemption Price,

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

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





                                       63
<PAGE>   71


          (5) 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

          (6) that the redemption is for a sinking fund, if such is the case.

     A notice of redemption published as contemplated by Section 1505 need not
identify particular Registered Securities to be redeemed.

     If any of the Securities to be redeemed is in the form of a Book Entry
Security, then the Company shall modify the notice of redemption to the extent
necessary to accord with the procedures of the Depositary applicable to
redemptions.

     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. Failure to give such
notice by mailing to any Holder of Securities or any defect therein shall not
affect the validity of any proceedings for the redemption of other Securities.

     SECTION 1105. DEPOSIT OF REDEMPTION PRICE.

     On or before 11:00 a.m., Eastern time, on any Redemption Date, the Company
shall deposit 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) immediately available funds in an amount sufficient to pay the
Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date) accrued interest on, all the Securities which are to be redeemed
on that date. Upon Company Order, the Paying Agent shall promptly return to the
Company any money so deposited which is not required for such purpose.






                                       64
<PAGE>   72


     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 accrued interest to
the Redemption Date; provided, however, that installments of interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only at an office or agency located outside the United States (except as
otherwise provided in Section 1002) and, unless otherwise specified as
contemplated by Section 301, only upon presentation and surrender of coupons for
such interest, and provided, further, that, unless otherwise specified as
contemplated by Section 301, 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 relevant Record Dates
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 interest
represented by coupons shall be payable only at an office or agency located
outside the United States (except as otherwise provided in Section 1002) and,
unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of those coupons.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal and any premium shall, until paid, 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 a Place of Payment therefor (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




                                       65
<PAGE>   73

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 and of like tenor, 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.

     SECTION 1108. PURCHASE OF SECURITIES.

     The Company shall have the right at any time and from time to time to
purchase securities in the open market or otherwise at any price.

                                 ARTICLE TWELVE

                                  SINKING FUNDS

     SECTION 1201. APPLICABILITY OF ARTICLE.

     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

     The minimum amount of any sinking fund payment provided for by the terms of
any Securities is herein referred to as a "mandatory sinking fund payment", and
any payment in excess of such minimum amount provided for by the terms of such
Securities is herein referred to as an "optional sinking fund payment". If
provided for by the terms of Securities of any series, the cash amount of any
sinking fund payment may be subject to reduction as provided in Section 1202.
Each sinking fund payment shall be applied to the redemption of Securities as
provided for by the terms of such Securities.

     SECTION 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

     The Company (1) may deliver Outstanding Securities of a series (other than
any previously called for redemption), together in the case of any Bearer
Securities of such series with all unmatured coupons appertaining thereto, and
(2) may apply as a credit Securities of a series which have been redeemed either
at the election of the Company pursuant to the terms of such Securities or
through the application of permitted optional sinking fund payments pursuant to
the terms of such Securities, in each case in satisfaction of all or any part of
any sinking fund payment with respect to any Securities of such series required
to be made pursuant to the terms of such Securities as and to the extent
provided for by the terms of such Securities, provided that the Securities to be
so credited have not been previously so credited. The Securities to be so
credited shall be received and credited for such purpose by the Trustee at the
Redemption Price, as specified in the Securities so to be redeemed, for
redemption




                                       66
<PAGE>   74

through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly.

     SECTION 1203. REDEMPTION OF SECURITIES FOR SINKING FUND.

     Not less than 45 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee a Company Order
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 1202 and will also deliver to the Trustee any Securities to be so
credited. Not less than 30 days before each such sinking fund payment date the
Company or the Trustee shall select the Securities to be redeemed upon such
sinking fund payment date in the manner specified in Section 1103 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Company in the manner provided in Section 1104. Such notice having been
duly given, the redemption of such Securities shall be made upon the terms and
in the manner stated in Sections 1106 and 1107.

     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, on) and interest on
     the Outstanding Securities and any coupons pertaining thereto on the Stated
     Maturity




                                       68

     thereof in accordance with the terms of this Indenture and of the
     Securities of such series. For this purpose, "U.S. Government Obligations"
     means securities that are (x) direct obligations of the United States of
     America for the timely payment of which its full faith and credit is
     pledged or (y) obligations of a Person controlled or supervised by and
     acting as an agency or instrumentality of the United States of America the
     timely payment of which is unconditionally guaranteed as a full faith and
     credit obligation by the United States of America, which, in either case,
     are not callable or redeemable at the option of the issuer thereof, and
     shall also include a depository receipt issued by a bank (as defined in
     Section 3(a)(2) of the Securities Act), as custodian with respect to any
     such U.S. Government Obligation or a specific payment of principal of or
     interest on any such U.S. Government Obligation held by such custodian for
     the account of the holder of such depository receipt, provided that (except
     as required by law) such custodian is not authorized to make any deduction
     from the amount payable to the holder of such depository receipt from any
     amount received by the custodian in respect of the U.S. Government
     Obligation or the specific payment of principal of or interest on the U.S.
     Government Obligation evidenced by such depository receipt.

          (2) No Event of Default or Event of Default with respect to the
     Securities of such series shall have occurred and be continuing on the date
     of such deposit or, insofar as subsections 501(5) and (6) are concerned, at
     any time during the period ending on the 91st day after the date of such
     deposit.

          (3) Such legal defeasance or covenant defeasance shall not cause the
     Trustee to have a conflicting interest under this Indenture and the Trust
     Indenture Act with respect to any securities of the Company.

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

          (5) In the case of an election under Section 1302, the Company shall
     have delivered to the Trustee an Opinion of Counsel stating that (x) the
     Company has received from, or there has been published by, the Internal
     Revenue Service a ruling, or (y) since the date of this Indenture there has
     been a change in the applicable federal income tax laws, in either case to
     the effect that, and based thereon such opinion shall confirm that, the
     Holders of the Outstanding Securities of such series will not recognize
     income, gain or loss for federal income tax purposes as a result of such
     legal 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 legal defeasance had not occurred.








                                       69
<PAGE>   77

          (6) In the case of an election under Section 1303, the Company shall
     have delivered to the Trustee an Opinion of Counsel to the effect that the
     Holders of the Outstanding Securities of such series 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.

          (7) The Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, which, taken together, state that
     all conditions precedent provided for relating to either the legal
     defeasance under Section 1302 or the covenant defeasance under Section 1303
     (as the case may be) have been complied with.

          (8) Such defeasance or covenant defeasance shall not result in the
     trust arising from such deposit constituting an investment company as
     defined in the Investment Company Act unless such trust shall be qualified
     under such Act or exempt from regulation thereunder.

     SECTION 1305. DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
TRUST; MISCELLANEOUS PROVISIONS.

     Subject to the provisions of the last paragraph of Section 1003, all money
and U.S. Government Obligations (including the proceeds thereof) deposited with
the Trustee (or other qualifying trustee collectively, for purposes of this
Section 1305, the "Trustee") pursuant to Section 1304 in respect of the
Outstanding Securities of such series shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities of such series 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 the Securities of such series, of all sums due and
to become due thereon in respect of principal (and premium, if any) and
interest, but such money need not be segregated from other funds except to the
extent required by law.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1304 or the principal and 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 the Outstanding Securities.

     Anything in this Article Thirteen to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 1304 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



                                       70
<PAGE>   78

then be required to be deposited to effect an equivalent legal defeasance or
covenant defeasance, as applicable, in accordance with this Article.

     SECTION 1306. REINSTATEMENT.

     If the Trustee or the Paying Agent is unable to apply any money in
accordance with Section 1305 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the
Securities of such series shall be revived and reinstated as though no deposit
had occurred pursuant to Section 1302 or 1303, as the case may be, until such
time as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 1305; provided, however, that if the Company makes any
payment of principal of (or premium, if any, on) or interest on any Security
following the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of the Securities of such series to receive such
payment from the money held by the Trustee or the Paying Agent.

                                ARTICLE FOURTEEN

                                HOLDERS' MEETINGS

     SECTION 1401. PURPOSES FOR WHICH MEETINGS MAY BE CALLED.

     If Securities of a series are issuable as Bearer Securities, a meeting of
Holders of Securities of such 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 action 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.

     (a) 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 in
London 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 1505, not less than 21 nor more than
120 days prior to the date fixed for the meeting.

     (b) In case at any time the Company, 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




                                       71
<PAGE>   79

action proposed to be taken at the meeting, and the Trustee shall not have made
the first publication of the notice of such meeting within 21 days after receipt
of such request 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 in London for
such meeting and may call such meeting for such purposes by giving notice
thereof as provided in subsection (a) of this Section.

     SECTION 1403. PERSONS ENTITLED TO VOTE AT MEETINGS.

     To be entitled to vote at any meeting of Holders a Person shall (a) be a
Holder of one or more Securities or (b) be a Person appointed by an instrument
in writing as proxy by a Holder of one or more Securities. The only Persons who
shall be entitled to be present or to speak at any meeting of Holders shall be
the Persons entitled to vote at such meeting and their counsel and any
representatives of the Trustee and its counsel and any representatives of the
Company and its counsel.

     SECTION 1404. QUORUM; ACTION.

     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. In the absence of a quorum within 30
minutes of the time appointed for any such meeting, the meeting shall, if
convened at the request of Holders of Securities of such series, be dissolved.
In any other case the meeting may be adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such meeting. 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(a), 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 Section 512 or the proviso to the first paragraph of
Section 902, any resolution presented to a meeting (or adjourned meeting duly
reconvened at which a quorum is present as aforesaid) may be adopted by the
affirmative vote of the Holders of a majority in principal amount of the
Outstanding Securities of that series; provided, however, that, any resolution
with respect to any request, demand, authorization, direction, notice, consent,
waiver or other action 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




                                       72
<PAGE>   80

vote of the Holders of such specified percentage in principal amount of the
Outstanding Securities of that series.

     To the extent consistent with the terms of this Indenture, 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 related coupons, whether or not present or
represented at the meeting.

     SECTION 1405. DETERMINATION OF VOTING RIGHTS; CONDUCT AND ADJOURNMENT OF
MEETINGS.

     (a) 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 a 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 1503 and the
appointment of any proxy shall be proved in the manner specified in Section 1503
or by having the signature of the Person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 1503 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 1503 or other proof.

     (b) The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Securities as provided in Section 1402(b), 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.

     (c) 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 the Outstanding
Securities of such series held or represented by him; provided, however, that no
vote shall be cast or counted at any meeting in respect of any Security
challenged as not Outstanding and ruled by the chairman of the meeting to be not
Outstanding. The chairman of the meeting shall have no right to vote, except as
a Holder of a Security of such series or proxy.

     (d) 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




                                       73
<PAGE>   81

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 duplicate of all votes cast at the meeting. A record, at least in
duplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to 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.

                                 ARTICLE FIFTEEN

                            MISCELLANEOUS PROVISIONS

     SECTION 1501. COMPLIANCE CERTIFICATES AND OPINIONS.

     Upon any application or request by the Company to the Trustee to take any
action under any provision of this Indenture, the Company shall furnish to the
Trustee such certificates and opinions as may be required under the Trust
Indenture Act. Each such certificate or opinion shall be given in the form of an
Officers' Certificate, if to be given by an officer of the Company, or an
Opinion of Counsel, if to be given by counsel, and shall comply with the
requirements of the Trust Indenture Act and any other requirements set forth in
this Indenture.

     Every certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture (except for certificates provided for in
Section 1006) shall include:

          (1) a statement that each individual signing such certificate or
     opinion has read such covenant or condition and the definitions herein
     relating thereto;


                                       74
<PAGE>   82

          (2) a brief statement as to the nature and scope of the examination or
     investigation upon which the statements or opinions contained in such
     certificate or opinion are based;

          (3) a statement that, in the opinion of each such individual, he has
     made such examination or investigation as is necessary to enable him to
     express an informed opinion as to whether or not such covenant or condition
     has been complied with; and

          (4) a statement as to whether, in the opinion of each such individual,
     such condition or covenant has been complied with.

     The certificates and opinions provided pursuant to this Section 1501 and
the statements required by this Section 1501 shall comply in all respects with
TIA Sections 314(c) and (e).

     SECTION 1502. FORM OF DOCUMENTS DELIVERED TO TRUSTEE

     In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

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

     Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

     SECTION 1503. ACTS OF HOLDERS; RECORD DATES.

     (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Indenture to be given or made or
taken by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor




                                       75
<PAGE>   83

signed by such Holders in person or by an agent duly appointed in writing or
deemed signed pursuant to the policies and procedures of the Depositary holding
the affected Securities, or otherwise. If Securities of a series are issuable as
Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders of such series may, alternatively, be embodied in and evidenced by
the record of Holders of Securities of such series voting in favor thereof,
either in person or by proxies duly appointed in writing, at any meeting of
Holders of Securities of such series duly called and held in accordance with the
provisions of Article Fourteen, or a combination of such instruments and any
such record. Except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments or record or both are
received by the Trustee and, where it is hereby expressly required, by the
Company. Such instrument or instruments and any such record (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Holders signing or deemed to be signing such instrument or
instruments and so voting at any such meeting. Proof of execution of any such
instrument or of a writing appointing any such agent or proxy or of the holding
by any Person of a Security, shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section. The record of any
meeting of Holders of Securities shall be proved in the manner provided in
Section 1406.

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

     (c) The Company may, in the circumstances permitted by the Trust Indenture
Act, fix any day as the record date for the purpose of determining the Holders
of Registered Securities of any series entitled to give or take any request,
demand, authorization, direction, notice, consent, waiver or other action, or to
vote on any action, authorized or permitted to be given or taken by Holders of
Securities of such series. If not set by the Company prior to the first
solicitation of a Holder of Securities of such series made by any Person in
respect of any such action, or, in the case of any such vote, prior to such
vote, the record date for any such action or vote shall be the 30th day (or, if
later, the date of the most recent list of Holders required to be provided
pursuant to Section 701) prior to such first solicitation or vote, as the case
may be. With regard to any record date for action to be taken by the Holders of
one or more series of Securities, only the Holders of Securities of such series
on such date (or their duly designated proxies) shall be entitled to give or
take, or vote on, the relevant action.



                                       76
<PAGE>   84

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

     (e) The principal amount and serial numbers of Bearer Securities held by
any Person, and the date 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, wherever situated, if such
certificate shall be deemed by 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 principal amount and
serial numbers of Bearer Securities held by any Person, and the date of holding
the same, may also be proved in any other manner which the Trustee deems
sufficient.

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

     (g) Without limiting the foregoing, a Holder entitled hereunder to give or
take any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any different part of such principal amount.

     SECTION 1504. NOTICES, ETC., TO TRUSTEE AND COMPANY.

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

          (1) the Trustee by any Holder or by the Company shall be sufficient
     for every purpose hereunder if made, given, furnished or filed in writing
     to or with the Trustee at its Corporate Trust Office, Attention: Corporate
     Trust Department, or



                                       77
<PAGE>   85

          (2) the Company by the Trustee or by any Holder shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided) if
     in writing and delivered in person, by facsimile transmission (Secretary
     (713) 756 1744) or mailed, by registered mail, return receipt requested,
     first class postage prepaid, to the Company addressed to it at the address
     of its principal office specified in the first paragraph of this instrument
     to the attention of the Chief Financial Officer, with a copy to be sent to
     Nuevo Energy Company, 1021 Main Street, Suite 2100, Houston, Texas 77002,
     Facsimile No. (713) 756 1744, Attention: Controller, or at any other
     address or facsimile number previously furnished in writing to the Trustee
     by the Company.

     SECTION 1505. NOTICE TO HOLDERS; WAIVER

     Except as otherwise expressly provided herein, where this Indenture
provides for notice to Holders of Securities of any event,

          (1) such notice shall be sufficiently given to Holders of Registered
     Securities if in writing and mailed, first class postage prepaid, to each
     Holder of a Registered Security affected by such event, at the address of
     such Holder as it appears in the Security Register, not later than the
     latest date (if any), and not earlier than the earliest date (if any),
     prescribed for the giving of such notice; and

          (2) such notice shall be sufficiently given to Holders of Bearer
     Securities if published in an Authorized Newspaper in The City of New York
     and in such other city or cities as may be specified in such Securities on
     a Business Day at least twice, the first such publication to be not earlier
     than the earliest date (if any), and not later than the latest date (if
     any), prescribed for the giving of such notice.

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

     In case by the reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither the failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any

notice so published, shall affect the sufficiency of any notice to Holders of
Registered Securities given as provided herein.

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

     SECTION 1506. LANGUAGE OF NOTICES, ETC.

     Any request, demand, authorization, direction, notice, consent or waiver
required or permitted under this Indenture shall be in the English language,
except that any published notice may be in an official language of the country
of publication.

     SECTION 1507. CONFLICT WITH TRUST INDENTURE ACT.

     This Indenture is subject to and shall be governed by the provisions of the
Trust Indenture Act that are required to be part of this Indenture. If any
provision hereof limits, qualifies or conflicts with a provision of the Trust
Indenture Act which is required under the Trust Indenture Act to be a part of
and govern this Indenture, the latter provision shall control. If any provision
of this Indenture modifies or excludes any provision of the Trust Indenture Act
which may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.

     SECTION 1508. EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

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

     SECTION 1510. SEPARABILITY CLAUSE.

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

     SECTION 1511. BENEFITS OF INDENTURE.

     Nothing in this Indenture or the Securities or coupons, express or implied,

equitable right, remedy or claim under this Indenture.

CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     SECTION 1513. LEGAL HOLIDAYS.

     In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
or coupons (other than a provision in the Securities of any series which
specifically states that such provision shall apply in lieu of this Section))
payment of interest or principal (and premium, if any) need not be made at such
Place of Payment on such date, but may be made on the next succeeding Business
Day at such Place of Payment with the same force and effect as if made on the
Interest Payment Date or Redemption Date, or at the Stated Maturity, provided
that no interest shall accrue on the amount so payable for the period from and
after such Interest Payment Date, Redemption Date or Stated Maturity, as the
case may be.

     SECTION 1514. NO RECOURSE AGAINST OTHERS.

     A director, officer, employee, stockholder, incorporator or Affiliate, as
such, past, present or future, of the Company shall not have any personal

as a director, officer, employee, stockholder, incorporator or Affiliate or any
liability for any obligations of the Company under the Securities or this
Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation. Each Holder, by accepting any of the Securities,
waives and releases all such liability to the extent permitted by applicable
law.

     SECTION 1515. EXECUTION IN COUNTERPARTS.

     This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

debt agreement may not be used to interpret this Indenture.

                              [Title of Securities]

                               (the "Securities")


     This is to certify that as of the date hereof, and except as set forth
below, the above captioned Securities held by you for our account (i) are owned
by person(s) that are not citizens or residents of the United States, domestic
partnerships, domestic corporations or any estate or trust the income of which
is subject to United States Federal income taxation regardless of its source
("United States persons"), (ii) are owned by United States person(s) that are
(A) foreign branches of United States financial institutions (as defined in U.S.
Treasury Regulations Section 1.165 12(c)(1)(v)) ("financial institutions")
purchasing for their own account or for resale, or (B) United States person(s)
who acquired Securities through the foreign branches of the United States
financial institutions and who hold the Securities through such United States
financial institutions on the date hereof (and in either case (A) or (B), each
such United States financial institution hereby agrees, on its own behalf or
through its agent, to comply with the requirements of Section 165(j)(3)(A), (B)
or (C) of the Internal Revenue Code of 1986 as amended, and the regulations
thereunder), or (iii) are owned by United States or foreign financial
institution(s) for purposes of resale during the restricted period (as defined
in U.S. Treasury Regulations Section 1.163 5(c)(2)(i)(D)(7)), and in addition if
the owner of the Securities is a United States or foreign financial institution
described in clause (iii) above (whether or not also described in clause (i) or
(ii)), this is to further certify that such financial institution has not
acquired the Securities for purposes of resale directly or indirectly to a
United States person or to a person within the United States or its possessions.

     If the Securities are of the category contemplated in Section 230.903(c)(3)
of Regulation S under the Securities Act of 1933, as amended (the "Act"), then
this is also to certify that, except as set forth below (i) in the case of debt
securities, the Securities are beneficially owned by (a) non-U.S. person(s) or
(b) U.S. person(s) who purchased the Securities in transactions which did not
require registration under the Act; or (ii) in the case of equity securities,
the Securities are owned by (x) non-U.S. person(s) (and such person(s) are not
acquiring the Securities for the account or benefit of U.S. person(s)), or (y)
U.S. person(s) who purchased the Securities in a transaction which did not
require registration under the Act. If this certification is being delivered in
connection with the exercise of warrants pursuant to Section 230.902(m) of
Regulation S under the Act, then this is further to certify that, except as set
forth below, the Securities are being exercised by and on behalf





                                       A-1

of non-U.S. person(s). As used in this paragraph, the term "U.S. person" has the
meaning given to it by Regulation S under the Act. As used herein, "United
States" or "U.S." means the United States of America (including the States and
District of Columbia); and its "possessions" include Puerto Rico, the U.S.
Virgin Islands, Guam, American Samoa, Wake Island and the Northern Mariana
Islands.

     We undertake to advise you promptly by tested telex on or prior to the date
on which you intend to submit your certification relating to the Securities held
by you for our account in accordance with your Operating Procedures if any
applicable statement herein is not correct on such date, and in the absence of
any such notification it may be assumed that this certification applies as of
such date.

     This certification excepts and does not relate to $_________ of such
interest in the above Securities in respect of which we are not able to certify
and as to which we understand exchange and delivery of definitive Securities
(or, if relevant, exercise of any rights or collection of any interest) cannot
be made until we do so certify.

     We understand that this certification is required in connection with
certain tax laws and, if applicable, certain securities laws of the United
States. In connection therewith, if administrative or legal proceedings are
commenced or threatened in connection with which this certification is or would
be relevant, we irrevocably authorize you to produce this certification to any
interested party in such proceedings.

     We understand that this certification is required in connection with
certain tax laws and, if applicable, certain securities laws of the United
States. In connection therewith, if administrative or legal proceedings are
