or exhibited to it, the Bearer Securities therein described; or such facts may
be proved by the certificates 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, (2) such
Bearer Security is produced to the Trustee by some other Person, (3) such Bearer
Security is surrendered in exchange for a Registered Security or (4) such Bearer
Security is no longer Outstanding.

writing pursuant to clause (c) above, the authority of the Person executing the
same and the principal amount and serial numbers of Bearer Securities held by
the Person so executing such instrument or writing and the date of holding the
same may also be proved in any other manner which the Trustee deems sufficient;
and the Trustee may in any instance require further proof with respect to any of
the matters referred to in this clause.

               (e)    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.

               (f)    Any request, demand, authorization, direction, notice,
consent, waiver or other Act of a Holder shall bind every future Holder of the
same Security and/or Coupon and the Holder of every Security and/or Coupon
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 and/or Coupon.

option, by or pursuant to a Board Resolution, fix in advance a record date for
the determination of Holders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other Act, but the Company
shall have no obligation to do so. Where the Company does not fix a record date
prior to the first solicitation of a Holder made by any Person in respect of any
such Act, the record date for any such Act shall be the 30th day (or, if later,
the date of the most recent list of Holders required to be provided pursuant to
Section 7.1) prior to such first solicitation. With regard to any record date,
any request, demand, authorization, direction, notice, consent, waiver or other
Act may be given before or after such record date, but only the Holders of
record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Securities have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that purpose the Outstanding Securities shall be computed as of
such record date; provided that- no such authorization, agreement or consent: by
the Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than six months
after the record date.

        1.5    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,

given, furnished or filed in writing to or with the Trustee at its Corporate
Trust Office and unless otherwise herein expressly provided, any such document
shall be deemed to be sufficiently made, given, furnished or filed upon its
receipt by a Responsible Officer of the Trustee, or

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

        1.6    NOTICE TO HOLDERS; WAIVER. Where this Indenture provides for
notice to Holders of any event:

               (a)    if any of the Securities affected by such event are
Registered Securities, such notice shall be sufficiently given (unless otherwise
herein expressly provided) if in writing and mailed, first-class postage
prepaid, to each Holder affected by such event, at his address as it appears in
the Security Register, within the time prescribed for the giving of such notice,
and

               (b)    if any of the Securities affected by such event are Bearer
Securities, such notice shall be sufficiently given (unless otherwise herein
expressly provided or unless otherwise specified in such Securities) if
published once in an Authorized Newspaper in New York City



                                       9
<PAGE>   11

and London and mailed to such Persons whose names and addresses were previously
filed with the Trustee, within the time 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 by
mail, then such notification as the Company shall direct the Trustee in writing
to give shall constitute a sufficient notification for every purpose hereunder.
In any case where notice to Holders is given by mail, neither the failure to
mail such notice, nor any defect in any notice so mailed, to any particular
Holder shall affect the sufficiency of such notice with respect to other
Holders.

        In case by 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 the Company
shall direct the Trustee in writing to give 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 of Securities 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.

        1.7    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 a part of this Indenture. If any provision hereof limits,
qualifies or conflicts with a provision of the Trust Indenture Act that is
required under such Act to be a part of and govern this Indenture, the latter

as shall be specified therein and may provide that it shall represent the

in global form to reflect the amount, or any increase or decrease in the amount,
of Outstanding Securities represented thereby shall be made by the Trustee in
such manner and upon instructions given by such Person or Persons as shall be
specified therein or in the Company Order to be delivered to the Trustee

and, if applicable, Section 3.4, the Trustee shall deliver and redeliver any
Security in definitive global bearer form in the manner and upon written
instructions given by the Person or Persons specified therein or in the

accompanied by an Opinion of Counsel.

        The provisions of the last sentence of the eighth paragraph of Section
3.3 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 1.2 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 the eighth paragraph of Section 3.3.

the preceding paragraph, the Company, the Trustee and any agent of the Company
and the Trustee shall treat a Person as the Holder of such principal amount of
outstanding Securities represented by a definitive global security as shall be

<PAGE>   16

               (o)    whether and under what circumstances and with what
procedures and documentation the Company will pay additional amounts on any of

        If any of the terms of the Securities of any series are established by
action taken pursuant to a Board Resolution, a copy of an appropriate record of
such action together with such Board Resolution shall be certified by the

<PAGE>   17


otherwise distinguished in such manner or in accordance with such plan as the
officers of the Company executing the same may determine with the approval of
the Trustee.

facsimile signatures of its Chairman of the Board, it President or any of its

Secretaries. Any Coupons shall be executed on behalf of the Company by the
manual or facsimile signature of any such officer 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 with the Company
Order shall authenticate and deliver such Securities; provided, however, that,
in connection with the sale of a Bearer Security during the "restricted period"
as defined in United States Treasury regulation Section 1.163-5(c)(2)(i)(D)(7),
no Bearer Security shall be mailed or otherwise delivered to any location in the
United States; and provided, further, that a definitive Bearer Security sold
during the restricted period may be delivered only outside the United States and
only if the Person entitled to receive such definitive Bearer Security shall
have furnished a certificate in the form set forth in Exhibit A.1 to this
Indenture, dated no earlier than 15 days prior to the earlier of the date on
which such definitive Bearer Security is delivered and the date on which any
temporary bearer Global Security first becomes exchangeable for such definitive
Bearer Security in accordance with the terms of such temporary Security and this
- Indenture. Except as permitted by Section 3.6, the Trustee shall not
authenticate and deliver any Bearer Security unless all appurtenant Coupons for
interest then matured have been detached and canceled.

        If all the Securities of a series are not to be originally issued at one
time, and if the Board Resolution, Officers' Certificate or supplemental
indenture establishing such series shall so permit, such Company Order may set
forth procedures acceptable to the Trustee for the issuance of such Securities
and the determination of the terms of particular Securities of such series such
as interest rate or rates (or the method in which such rate or rates are to be
determined) , if any, Stated maturity, date of issuance and date from which
interest, if any, shall accrue.

        If the forms or terms of the Securities of the series and any related
Coupons have been established by or pursuant to one or more Board Resolutions as
permitted by Sections 2.1 and 3.1, 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 6.1) shall be fully protected in relying upon, an Opinion of Counsel
stating:



                                       16
<PAGE>   18

               (a)    if the forms of such Securities and any Coupons have been
established by or pursuant to a Board Resolution as permitted by Section 2.1,
that such forms have been established in conformity with the provisions of this
indenture; and

               (b)    if the terms of such Securities and any Coupons have been
established by or pursuant to a Board Resolution as permitted by Section 3.1,
that such terms have been established in conformity with the provisions of this
Indenture.

        Notwithstanding the provisions of Section 3.1 and of the preceding
paragraph, 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 3.1 or the Company Order and opinion of Counsel
otherwise required pursuant to such preceding paragraph 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 original issuance of the first
Security of such series to be issued.

        Each Registered Security shall be dated the date of its authentication;
and each Bearer Security and any Bearer Security in global form 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 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 duly 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 3.9
together with a written statement (which need not comply with Section 1.2 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.

        If the Company shall establish pursuant to Section 3.1 that the
Securities of a series are to be issued in whole or in part in the form of a
Global Security, then the Company shall execute and the Trustee shall in
accordance with this Section and the Company order with respect to such series
authenticate and deliver the Global Security that (i) shall represent and shall
be denominated in an aggregate amount equal to the aggregate principal amount of
Outstanding Securities of such series to be represented by the Global Security,
(ii) shall be registered, if in registered form, in the name of the Depositary
for such Global Security or the nominee of such Depositary, (iii) shall be
delivered by the Trustee to such Depositary or pursuant to such Depositary's
instruction, and (iv) shall bear a legend substantially to the following effect:
"Unless and until this Security is exchanged in whole or in part for Securities
in definitive form, this Security may not be transferred except 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



                                       17
<PAGE>   19


Depositary or by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary" or to such other effect as the
Depositary and the Trustee may agree.

        Each Depositary designated pursuant to Section 3.1 for a Global Security
in registered form must, at the time of its designation and at all times while
it serves as Depositary, be a clearing agency registered under the Securities
Exchange Act of 1934 and any other applicable statute or regulation. The Trustee
shall have no responsibility to determine if the Depositary is so registered.

        3.4    TEMPORARY SECURITIES. Pending the preparation of definitive
Securities of any series, the Company may execute, and upon Company Order the
Trustee shall authenticate and deliver, temporary Securities 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, (i) in registered form or (ii) 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 conclusively by their execution of such
Securities. Such temporary Securities may be (in the case of Registered
Securities) and shall be (in the case of Bearer Securities) in global form.

        Except in the case of temporary Global Securities in bearer form (which
are exchangeable for definitive Bearer Securities 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 of agency of the Company
maintained pursuant to Section 10.2 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 and authorized denominations; provided, however, that
no definitive Bearer Security shall be delivered in exchange for a temporary
Registered Security; and provided, further, that a definitive Bearer Security
(including a definitive Bearer Security in global form) shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth in Section 3.3.

        If temporary Global Securities in bearer form of any series are issued,
any such temporary global Securities in bearer form shall, unless otherwise
provided therein, be delivered to the London office of a 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 in bearer form (the



                                       18
<PAGE>   20

"Exchange Date"), the Company shall deliver to the Trustee definitive
Securities, in aggregate principal amount equal to the principal amount of such
temporary global Security in bearer form, executed by the Company. On or after
the Exchange Date, such temporary global Security in bearer form 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 without charge and the Trustee shall authenticate and
deliver, in exchange for each portion of such temporary global Security in
bearer form, an equal aggregate principal amount of definitive Securities of the
same series of authorized denominations and of like tenor as the portion of such
temporary global Security in bearer form to be exchanged. The definitive
Securities to be delivered in exchange for any such temporary global Security in
bearer form shall be in bearer form, registered form, definitive global form
(registered or bearer), or a combination thereof, as specified as contemplated
by Section 3.1, and, if a combination thereof is so specified, as requested by
the beneficial owner thereof; provided, however, that, unless otherwise
specified in such temporary global Security in bearer form, upon such
presentation by the Common Depositary, such temporary global Security in bearer
form shall be 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 in bearer form 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 in bearer form held for
its account then to be exchanged, each in the form set forth in Exhibit A.2 to
this Indenture; and provided, further, that definitive Bearer Securities shall
be delivered in exchange for a portion of a temporary global Security in bearer
form only in compliance with the requirements of Section 3.3.

        Unless otherwise specified in such temporary global Security in bearer
form, the interest of a beneficial owner of Securities of a series in a
temporary global Security in bearer form shall be exchanged for definitive
Securities of the same series and of like tenor following the Exchange Date when
the beneficial owner instructs Euro-clear or CEDEL, S.A., as the case may be, to
request such exchange on his behalf and delivers to Euro-clear or CEDEL, S.A.,
as the case may be, a certificate in the form set forth in Exhibit A.1 of this
Indenture, dated no earlier than 15 days prior to the Exchange Date, copies of
which certificate shall be available from the offices of Euro-clear, CEDEL,
S.A., the Trustee, any Authenticating Agent appointed for such series of
Securities and any Paying Agent appointed for such series of Securities. Unless
otherwise specified in such temporary global Security in bearer form, any such
exchange shall be made free of charge to the beneficial owners of such temporary
global Security in bearer form, 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. The definitive
Securities in bearer form to be delivered in exchange for any portion of a
temporary global Security in bearer form 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 3.1, interest payable on a temporary global

<PAGE>   21

Security in bearer form on an Interest Payment Date for Securities of such
series occurring prior to the applicable Exchange Date shall be 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 A.2 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 in
bearer form (or to such other accounts as they may direct) 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 Exhibit A.1 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 10.3.

        3.5    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 10.2 a register (being the combined register of the
Security Registrar and all transfer agents designated pursuant to Section 10.2
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 Registered Securities and the registration of transfers of
Registered Securities. The Trustee is hereby appointed "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 10.2 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 aggregate
principal amount and tenor.

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

        The Company may establish pursuant to Section 3.1 that, at the option of
the Holder (subject to Section 3.3), 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 unmatured Coupon
or Coupons or



                                       20
<PAGE>   22

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 if there is furnished to each of them such security or
indemnity as each 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 10.2,
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 3.1, any definitive global Bearer Security shall be
exchangeable only as provided in this paragraph. If the beneficial owners of
interests in a definitive global Bearer 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 3.1, then without unnecessary delay but in any event not later than the
earliest date on which such interests may be so exchanged, the Company shall
deliver to the Trustee definitive Securities in aggregate principal amount equal
to the principal amount of such definitive global Bearer Security, executed by
the Company. On or after the earliest date on which such interests may be so
exchanged, such definitive global Bearer Security shall be surrendered by the
Common Depositary or such or other depositary or Common 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 from time to time
in part, for definitive Securities without charge and the Trustee shall
authenticate and deliver, in exchange for each portion of such definitive global
Bearer Security, an equal aggregate principal amount of definitive Securities of
the same series of authorized denominations and of like tenor as the portion of
such definitive global Bearer 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 3.1, shall be in
the form of Bearer Securities or Registered Securities or any combination
thereof, as shall be



                                       21
<PAGE>   23

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 to be redeemed and ending on
the relevant Redemption Date; and provided, further, that no Bearer Security
delivered in exchange for a portion of a definitive global Security shall be
mailed or otherwise delivered to any location in the United States. If a
Registered Security is issued in exchange for any portion of a definitive global
Bearer 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 maybe, 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 definitive global Bearer Security is
payable in accordance with the provisions of this Indenture.

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

        Every Registered Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Company or the Trustee 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 3.4, 9.6 or 1107 not involving any transfer.

        The Company shall not be required (i) to issue, register the transfer of
or exchange Securities of any series during a period beginning at the opening of
business 15 days before any selection of Securities of that series to be
redeemed 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 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.



                                       22
<PAGE>   24

        If at any time the Depositary for the Securities .of a series notifies
the Company that it is unwilling or unable to continue as Depositary for the
Securities of such series or if at any time the Depositary for the Securities of
such series shall no longer be eligible under Section 3.3, the Company shall
appoint a successor Depositary with respect to the Securities of such series. If
a successor Depositary for the Securities of such series is not appointed by the
Company within 90 days after the Company receives such notice or becomes aware
of such ineligibility, the Company's election pursuant to Section 3.1 shall no
longer be effective with respect to the securities of such series and the
Company will execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of definitive Securities of such series, will
authenticate and deliver, Securities of such series in definitive form in an
aggregate principal amount equal to the principal amount of the Global Security
representing such series in exchange for such Global Security.

        If specified by the Company pursuant to Section 3.1 with respect to a
series of Securities, the Company may at any time and in its sole discretion
determine that the Securities of any series issued in the form of one or more
Global Securities shall no longer be represented by such Global Security or
Securities. In such event the Company will execute, and the Trustee, upon
receipt of a Company Order for the authentication and delivery of definitive
Securities of such series, will authenticate and deliver Securities of such
series in definitive form and in an aggregate principal amount equal to the
principal amount of the Global Security or Securities representing such series
in exchange for such Global Security or Securities.

        If specified by the Company pursuant to Section 3.1 with respect to a
series of Securities, the Depositary for such series of Securities may surrender
a Global Security for such series of Securities in exchange in whole or in part
for Securities of such series in definitive form on such terms as are acceptable
to the Company and such Depositary; provided, however, that no portion of a
Global Security in registered form may be surrendered in exchange for Securities
in bearer form. Thereupon, the Company shall execute; and the Trustee, upon
receipt of a Company Order for the authentication and delivery of definitive
Securities of such series, shall authenticate and deliver, without charge to the
Holders,

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

                      (ii)   to such Depositary a new Global Security in a
denomination equal to the difference, if any, between the principal amount of
the surrendered, Global Security and the aggregate principal amount of
Securities delivered to Holders thereof.

        In any exchange provided for in any of the preceding three paragraphs,
the Company will execute and the Trustee will authenticate and deliver
Securities (a) in definitive registered form in authorized denominations, if the
Securities of such series are issuable as Registered Securities, (b) in
definitive bearer form in authorized denominations, with coupons attached, if
the Securities of such series are issuable as Bearer Securities or (c) as either
Registered or Bearer



                                       23
<PAGE>   25

Securities, if the Securities of such series are issuable in either form;
provided, however, that a Bearer Security may not be delivered in exchange for a
Registered Security, and provided, further, that a definitive Bearer Security
shall be delivered in exchange for a temporary Global Security in bearer form
only in compliance with the conditions set forth in Section 3.3 and provided,
further, that delivery of a Bearer Security shall be made only outside the
United States.

        Upon the exchange of a Global Security for Securities in definitive
form, such Global Security shall be canceled by the Trustee, Registered
Securities issued in exchange for a Global Security pursuant to this Section
shall be registered in such names and in such authorized denominations as the
Depositary for such Global Security, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee in writing. The
Trustee shall deliver such Registered Securities to the persons in whose names
such Securities are so registered.

        Notwithstanding any other provisions of this Section to the contrary,
unless and until a Global Security is exchanged in whole for Securities in
definitive form, a Global Security representing all or a portion of the
Securities of a series may not be transferred except as a whole by the
Depositary for such series to a nominee of such Depositary or by a nominee of
such Depositary to such Depositary or another nominee of such Depositary or by
such Depositary or any such nominee to a successor Depositary for such series or
a nominee of such successor Depositary.

        3.6    MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES. If any
mutilated Security or Security with a mutilated Coupon appertaining to it 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 each of their satisfaction of the destruction, loss or theft of any Security
or Coupon and (ii) such security or indemnity as may be required by each of 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 (upon surrender to the Trustee of such Security 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, it
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 or Coupon, pay such Security or Coupon;
provided, however, that principal of (and



                                       24
<PAGE>   26

premium, if any) and any interest on Bearer Securities shall, except as
otherwise provided in Section 10.2, be payable only at an office or agency
located outside the United States and, unless otherwise specified as
contemplated by Section 3.1, any interest on Bearer Securities shall be payable
only upon presentation and surrender of the Coupons appertaining thereto.

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

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

        3.7    PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED. Unless otherwise
provided as contemplated by Section 3.1 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.

        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:

               (a)    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 Security of such series and the date of the proposed payment, and at the
same time the Company shall deposit with the Trustee an amount of money equal to
the aggregate amount proposed to be paid in respect of such Defaulted Interest
or shall make arrangements satisfactory to the Trustee for such deposit prior to
the date of the proposed payment, such money when deposited to be held in trust
for the benefit of the Persons entitled to such Defaulted Interest as in this
Clause provided. Thereupon the Trustee shall fix a Special Record Date for the
payment of such Defaulted Interest which shall not all be more than 10 days and
not less than 10 days prior to the date of the



                                       25
<PAGE>   27

proposed payment and not less than 10 days after the receipt by the Trustee of
the notice of the proposed payment. The Trustee shall promptly notify the
Company of such Special Record Date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor to be mailed, first-class postage prepaid,
to each Holder of Securities of such series at his address as it appears in the
Security Register, not less than 10 days prior to such Special Record Date.
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 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).

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

        Subject to the foregoing provisions of this Section and Section 3.5,
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, and, subject as aforesaid, each such Security shall be so dated, or
have attached thereto such Coupons, that neither gain nor loss in interest shall
result from such transfer, exchange or substitution.

        3.8    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 3.5 and 3.) 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 Holder of any Bearer Security and the Holder of any Coupon
as the absolute 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.

        Notwithstanding the foregoing, with respect to any Global 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 any Depositary, as a



                                       26
<PAGE>   28

Holder, with respect to such Global Security or impair, as between such
Depositary and owners of beneficial interests in such Global Security, the
operation of customary practices governing the exercise of the rights of such
Depositary (or its nominee) as Holder of such Global Security. Neither the
Company, the Trustee, nor any agent of the Company or, the Trustee, will have
any responsibility or liability for any aspects of the records relating to or
payments made on account of beneficial ownership interests in a Global Security
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

        3.9    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 such Securities and Coupons so delivered, and
all such Securities and Coupons so surrendered to the Trustee, shall be promptly
canceled by the Trustee. All Bearer Securities and unmatured Coupons held by the
Trustee pending such cancellation shall be deemed to be delivered for
cancellation 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
Securities shall be authenticated in lieu of or in exchange for any Securities
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 a manner selected by the Trustee and the Trustee shall deliver a
certificate evidencing such destruction to the Company.

        3.10   COMPUTATION OF INTEREST. Except as otherwise specified as
contemplated by Section 3.1 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.

        3.11   MANNER OF PAYMENTS IN RESPECT OF SECURITIES. The provisions of
this Section shall apply to the Securities of any series unless otherwise
provided as contemplated by Section 3.1.

               (a)    The following payment provisions shall apply to any
Registered Security of any series:

                             (i)    Except as provided in subparagraph (a)(2)
below, payment of principal of and premium, if any, on such Registered Security
will be made at the Place of Payment by delivery of a check on the payment date
or dates against surrender of such Registered Security, and any interest on any
Registered Security will be paid at the Place of Payment by mailing a check by
first class mail to the Person entitled thereto at the address of such Person
appearing on the Security Register.



                                       27
<PAGE>   29

                             (ii)   Payment of the principal of, premium, if
any, And interest, if any, on such Security may also, subject to applicable laws
and regulations, be made at such other place or places as may be designated by
the Company by any appropriate method.

               (b)    Payment of the principal of and premium, if any, and
interest, if any, on any Bearer Security will be made, except as provided in
Section 3.4 with respect to temporary global Securities, unless otherwise
specified pursuant to Section 3.1 and/or Section 901(8), at such place or places
outside the United States as may be designated by the Company pursuant to any
applicable laws or regulations by any appropriate method on the payment date
therefor against surrender of the Bearer Security, in the case of payment of

interest, if any, to a Paying Agent designated for such series pursuant to
Section 10.2.

               (c)    Not later than 10 Business Days (with respect to any Place
of Payment) prior to each payment date, the Trustee shall deliver to the Company
a copy of its record of the respective aggregate amounts of principal of,
premium, if any, and interest, if any, on the Securities to be made on such
payment date, specifying the amounts so payable in respect of Registered
Securities and Bearer Securities.

        3.12   COMPLIANCE WITH CERTAIN LAWS AND REGULATIONS. If any Bearer
Securities are to be issued in any series of Securities, the Company will use
reasonable efforts to provide for arrangements and Procedures designed pursuant
to then applicable laws and regulations, if any, to ensure that such Bearer
Securities are sold or resold, exchanged, transferred and paid only in
compliance with such laws and regulations and without adverse consequences to
the Company, the Holders and the Trustee.

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

                                   ARTICLE IV
                           SATISFACTION AND DISCHARGE

4.1     SATISFACTION AND DISCHARGE OF INDENTURE. This Indenture shall upon
Company Request cease to be of further effect (except as to any surviving rights
of (as applicable) registration of transfer or exchange of Securities and
Coupons, if any, of any series herein expressly provided for), and the Trustee,
at the expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture when

               either

               (a)    all Securities and Coupons theretofore authenticated and
delivered (other than (i) Securities and Coupons which have been destroyed, lost
or stolen and which have been replaced or paid as provided in Section 3.6 and
(ii) Securities and Coupons for whose payment money has theretofore been

               (b)    all such Securities and Coupons not theretofore delivered
to the Trustee for cancellation

                             (i)    have become due and payable, or

                             (ii)   will become due and payable at their Stated

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 (b) (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,
               principal (and premium, if any) and interest, if any, to the date
               of such deposit in the case of Securities and Coupons 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
               payable hereunder by the Company; and

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

        Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.7, the obligations of
the Company to any Authenticating Agent under Section 6.14 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section, the obligations of the Trustee under Section 4.2 and the last
paragraph of Section 10.3 shall survive.

        4.2    APPLICATION OF TRUST MONEY. Subject to the provisions of the last
paragraph of Section 10.3, all money deposited with the Trustee pursuant to
Sections 4.1 and 4.3 shall be held in trust and applied by it, in accordance
with the provisions of the Securities and Coupons, if any, 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 premium, if any) and any
interest for whose payment such money has been deposited with the Trustee; but
such money need not be segregated from other funds except to the extent required
by law.

        4.3    SATISFACTION, DISCHARGE AND DEFEASANCES OF SECURITIES OF ANY
SERIES. If this Section is specified, as contemplated by Section 3.1, to be
applicable to Securities and Coupons,



                                       29
<PAGE>   31

if any, of any series, the Company will be deemed to have been Discharged (as
defined below) from its obligations with respect to Securities and Coupons, if
any, of such series when

               (a)    either

                             (i)    with respect to all Outstanding Securities
and Coupons of such series, the Company has deposited or caused to be deposited
with the Trustee as a trust fund specifically pledged as security for, and
dedicated solely to, the benefit of the Holders of the Securities and Coupons,
if any, of such series,

                             (ii)   money in an amount as will, or

                                    (1)    U.S. Government Obligations (as
defined below) as will, together with the predetermined and certain income to
accrue thereon without consideration of any reinvestment thereof, or

                                    (2)    a combination of (i) and (ii) as will
(in a written opinion with respect to (1) or (2) of independent public
accountants delivered to the Trustee), be sufficient to pay and discharge the
entire indebtedness on all Outstanding Securities and Coupons of such series for
principal (and premium, if any) and interest, if any, to the Stated Maturity or
any Redemption Date as contemplated by the last paragraph of this Section 4.3,
as the case may be; or

                                    (3)    with respect to all Outstanding
Securities and Coupons of such series, the Company has properly fulfilled such
other means of satisfaction and discharge as is specified by Section 3.1 to be
applicable to the Securities and Coupons, if any, of such series; and

               (b)    the Company has paid or caused to be paid all other sums
payable with respect to the Outstanding Securities and Coupons, if any, of such
series;

               (c)    the Company has delivered to the Trustee an Officer's
Certificate and an opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of the
entire indebtedness on all Outstanding Securities and Coupons, if any, of any
such series have been complied with; and

               (d)    with respect to subsection 1(a) above, the Company shall
have delivered to the Trustee (A) a ruling directed to the Company and the
Trustee received from the United States Internal Revenue Service to the effect
that the Holders of the Securities of such series will not recognize income,
gain or loss for Federal income tax purposes as a result of the Company's
exercise of its option under this Section 4.3 and will be subject to Federal
income tax on the same amount and in the same manner and at the same times as
would have been the case if such deposit and discharge had not occurred, (B) an
Opinion of Counsel to the same effect as the ruling described in clause (A)
above and based upon a change in law.



                                       30
<PAGE>   32

        Any deposits with the Trustee referred to in Section 4.3(a) above shall
be irrevocable and shall be made under the terms of an escrow trust agreement in
form and substance satisfactory to the Trustee. If any Outstanding Securities
and Coupons, if any, of such series are to be redeemed prior to their Stated
Maturity, whether pursuant to any mandatory redemption provisions or in
accordance with any mandatory sinking fund requirement, the applicable escrow
trust agreement will provide therefor and the Company will make arrangements for
the giving of notice of redemption by the Trustee in the name, and at the
expense, of the Company.

        4.4    REINSTATEMENT. If the Trustee is unable to apply any money or
U.S. Government Obligations in accordance with Section 4.1 or 4.3 by reason of
any legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company's obligations under this Indenture and the Securities
and Coupons, if any, of such series shall be revived and reinstated as though no
deposit had occurred pursuant to Section 4.1 or 4.3 until such time as the
Trustee is permitted to apply all such money or U.S. Governmental Obligations in
accordance with Section 4.1 or 4.3; provided, however, that if the Company has
made any payment of interest on or principal of (and premium, if any, on) any
Securities and Coupons, if any, of such series because of the reinstatement of
its obligations, the Company shall be subrogated to the rights of the Holders of
such series of Securities and Coupons, if any, to receive such payment from the
money or U.S. Government Obligations held by the Trustee.

        4.5    DEFINITIONS. The following terms, as used in this Article IV,
shall have the following meanings:

        "Discharged" means that the Company will be deemed to have paid and
discharged the entire indebtedness represented by, and obligations under, the
Securities and Coupons, if any, of the series as to which Section 4.3 is
specified as applicable as aforesaid and to have satisfied all the obligations
under this Indenture relating to the Securities and Coupons, if any, of such
series (and the Trustee, at the expense of the Company, will execute proper
instruments acknowledging the same), except (A) the rights of Holders thereof to
receive, from the trust fund described in Section 4.3(i)(A) above, payment of
the principal of (and premium, if any) and the interest, if any, on such
Securities and Coupons, if any, when such payments are due, (B) the Company's
obligations with respect to such Securities and Coupons, if any, under Sections
3.5 and 3.6 (insofar as applicable to Securities of such series), 4.2, 10.2 and
10.3 (last paragraph only) and the Company's obligations to the Trustee under
Sections 6.7 and 6.10, and (C) the rights, powers, trusts, duties and immunities
of the Trustee hereunder, will survive such discharge.

        "U.S. Government Obligations" means securities that are (i) direct
obligations of the United States of America for the payment of which its full
faith and credit is pledged or (ii) 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 of the United States of America, which, in either
case under clauses (i) or (ii), are not callable or redeemable at the option of
the issuer thereof, and will also include a depository receipt issued by a bank
or trust company as custodian with respect to any such U.S. Government
Obligation or a specified payment of interest on or principal of any such



                                       31
<PAGE>   33

U.S. Government Obligation held by such custodian for the account of the holder
of a 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 interest on
or principal of the U.S. Government Obligation evidenced by such depository
receipt.

                                    ARTICLE V
                                    REMEDIES

5.1     EVENTS OF DEFAULT. "Event of Default", wherever used herein with respect
to Securities of any series, means any one of the following events, unless it is
either inapplicable to a particular series or it is specifically deleted or
modified in or pursuant to the supplemental indenture or Board Resolution
establishing such series of Securities or in the form of Security for such
series:

               (a)    the failure of the Company to pay any installment of
interest on any of the Securities of that series, when and as the same shall
become payable, which failure shall have continued unremedied for a period of
30 days (whether or not such payment is prohibited under the provisions of
Article XV);

               (b)    the failure of the Company to pay the principal of (and
premium, if any, on) any of the Securities of that series, when and as the same
shall become payable, whether at Stated Maturity as therein expressed, by call
for redemption, pursuant to any sinking fund, by declaration as authorized by
this Indenture or otherwise (whether or not such payment is prohibited under the
provisions of Article XV);

               (c)    the failure of the Company to observe and perform any
other of the covenants or agreements on the part of the Company contained in
this Indenture (other then a covenant or agreement included in this Indenture
solely for the benefit of a series of Securities other than that series), which
failure shall have continued unremedied for a period of 90 days after written
notice shall have been given, by registered or certified mail, to the Company by
the Trustee, or shall have been given to the Company and the Trustee by the
Holders of 25% or more in principal amount of the Securities of that series then
Outstanding, specifying such failure and requiring the Company to remedy the
same and stating that such notice is a "Notice of Default" hereunder;

               (d)    the entry of a decree or order for relief by a court
having jurisdiction in the premises in respect of the Company in an involuntary
case under the Federal bankruptcy laws, as now or hereafter constituted, or any
other applicable Federal or State bankruptcy, insolvency or other similar law,
or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator
(or other similar official) of the Company or for any substantial part of its
property, or ordering the winding up or liquidation of its affairs and the
continuance of any such decree or order unstayed and in effect for a period of
90 consecutive days;



                                       32
<PAGE>   34

               (e)    the commencement by the Company of a voluntary case under
the Federal bankruptcy laws, as now constituted or hereafter amended, or any
other applicable Federal or State bankruptcy, insolvency or other similar law,
or the consent by it to the appointment of or taking possession by a receiver,
liquidator, assignee, trustee, custodian, sequestrator (or other similar
official) of the Company or for any substantial part of its property, or the
making by it of any assignment for the benefit of its creditors, or the
admission by the Company in writing of its inability to pay its debts generally
as such debts become due;

               (f)    an event of default, as defined in any mortgage, indenture
(including this Indenture), trust agreement or other instrument securing,
evidencing or providing for any Debt of the Company as a result of which Debt of
the Company in excess of $25,000,000 aggregate principal amount shall be or
become due and payable prior to the date on which the same would otherwise
become due and payable (except that such amount shall be $20,000,000 in respect
of a default on Securities of another series) and such acceleration shall not
have been annulled or rescinded within 30 days of notice of such acceleration to
the Company; provided, however, that, if such event of default with respect to
such other series of Securities or under such indenture or instrument, as the
case may be, shall be remedied or cured by the Company or waived by the holders
of such other series of Securities or the holders of such indebtedness, as the
case may be, pursuant to this Indenture or such indenture or instrument, as the
case may be, then unless the maturity of the Securities of such series shall
have been accelerated as provided herein, the Event of Default hereunder by
reason thereof shall be deemed likewise to have been thereupon remedied, cured
or waived without further action upon the part of either the Trustee or the
holders of such series; or

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

        5.2    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 the Securities of that series
are Original Issue Discount Securities, such portion of the principal amount as
may be specified in the terms of that series) of all of the Securities of 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 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

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



                                       33
<PAGE>   35

                             (i)    all overdue interest on all Securities of
that series,

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

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

                             (iv)   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

               (b)    all Events of Default with respect to Securities of that
series, other than the nonpayment of the principal of Securities of that series
which have become due solely by such declaration of acceleration, have been
cured or waived as provided in Section 5.13.

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

        5.3    COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.
The Company covenants that if the Company shall fail for a period of 30 days to
pay any installment of interest on the Securities of any series or shall fail to
pay the principal of (and premium, if any, on) any of the Securities of any
series when and as the same shall become due and payable, whether at Stated
Maturity, or by call for redemption, pursuant to any sinking fund, by
declaration as authorized by this Indenture, or otherwise, the Company will,
upon demand of the Trustee, pay to it, for the benefit of the Holders of such
Securities and Coupons, if any, the whole amount then due and payable on such
Securities and Coupons, if any, for principal (and premium, if any) and interest
and, to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal (and premium, if any) and on any overdue
interest, at the rate or rates prescribed therefor in such Securities (or, in
the case of Original Issue Discount Securities, the Securities; Yield to
Maturity) and Coupons, if any, 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 and Coupons, if any,
of any series occurs and is continuing, the Trustee may in its discretion
proceed to protect and enforce its rights and the rights of the Holders of
Securities of such series by such appropriate judicial proceedings as the
Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this
Indenture or in aid of the exercise of any power granted herein, or to enforce
any other proper remedy.



                                       34
<PAGE>   36

        5.4    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 6.7.

        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.

        5.5    TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES. All
rights of action and claims under this Indenture or the Securities and Coupons,
if any, may be prosecuted and enforced by the Trustee without the possession of
any of the Securities 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 the 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, if any, in respect
of which such judgment has been recovered.

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

        FIRST:  to the payment of all amounts due the Trustee under Section 6.7;

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

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



                                       35
<PAGE>   37

        5.7    LIMITATION ON SUITS. No Holder of any Security of any series
shall have any right to institute any proceeding, judicial or otherwise, with
respect to this Indenture, or for the appointment of a receiver or trustee, or
for any other remedy hereunder, unless

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

               (b)    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;

               (c)    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;

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

               (e)    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 the right
in any manner whatever by virtue of, or by availing of, any provision of this
Indenture (including without limitation the provisions of Section 5.12) 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.

        5.8    UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND
interest. Notwithstanding any other provision in this Indenture, the Holder of
any Security or any Coupon shall have the right, which is absolute and
unconditional, to receive payment of the principal of (and premium, if any, on)
and (subject to Section 3.7) any interest on such Security or Coupon on the
Stated Maturity or Maturities expressed in such Security (or, in the case of
redemption, on the Redemption Date) and to institute suit for the enforcement of
any such payment, and such rights shall not be impaired without the consent of
such Holder.

        5.9    RESTORATION OF RIGHTS AND REMEDIES. If the Trustee or any Holder
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 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.

        5.10   RIGHTS AND REMEDIES CUMULATIVE. Except as provided with respect
to the replacement or payment of mutilated, destroyed, lost or stolen Securities
in the last paragraph of



                                       36
<PAGE>   38

Section 3.6, no right or remedy herein conferred upon or reserved to the Trustee
or to the Holders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

        5.11   DELAY OR OMISSION NOT WAIVER. No delay or omission of the Trustee
or of any Holder of any Securities to exercise any right or remedy accruing upon
any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or any acquiescence therein. Every right and
remedy given by this Article or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders, as the case may be.

        5.12   CONTROL BY HOLDERS. The Holders of not less than 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

               (a)    such direction shall not be in conflict with any rule of
law or with this Indenture,

               (b)    the Trustee shall not determine that the action so
directed would be unjustly prejudicial to the Holders not taking part in such
direction,

               (c)    the Holders have provided the Trustee reasonable indemnity
against costs, expenses and liabilities to be incurred, and

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

        5.13   WAIVER OF PAST DEFAULTS. The Holders of not less than a majority
in principal amount of the Outstanding Securities of any series may on behalf of
the Holders of all the Securities of such series waive any past default
hereunder with respect to such series and its consequences, except a default

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

               (b)    in respect of a covenant or provision hereof which under
Article IX 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 shall cease to exist with respect to
such series, and any Event of Default with respect to such series arising
therefrom shall be deemed to have been



                                       37
<PAGE>   39

cured, for every purpose of this Indenture; but no such waiver shall extend to
any subsequent or other default or impair any right consequent thereon.

        5.14   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 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.

                                   ARTICLE VI
                                   THE TRUSTEE

6.1     CERTAIN DUTIES AND RESPONSIBILITIES.

               (a)    Except during the continuance of an Event of Default.

                             (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

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

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

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

                             (i)    this Subsection shall not be construed to
limit the effect of Subsection (a) of this Section;

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



                                       38
<PAGE>   40

                             (iii)  the Trustee shall not be liable with respect
to any action taken or omitted to be taken by it in good faith in accordance
with the direction of the Holders of a majority in principal amount of the
Outstanding Securities of any series, determined as provided in Sections 1.1,
1.4 and 5.12, relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred upon the Trustee, under this Indenture with respect to the
Securities of such series; and

                             (iv)   no provision of this Indenture shall require
the Trustee to 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 or
liability is not reasonably assured to it.

               (d)    Whether or not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section.

        6.2    NOTICE OF DEFAULTS. If a default occurs hereunder with respect to
Securities of any series, the Trustee shall give the Holders of Securities of
such series notice of such default actually known to the Trustee as and to the
extent provided by the Trust Indenture Act; provided, however, that in the case
of any default of the character specified in Section 5.1(c) with respect to
Securities of such series, no such notice to Holders shall be given until at
least 30 days after the occurrence thereof and if such default is corrected
within such period, the Trustee may conclude, consistent with the Trust
Indenture Act, that notice of such a default need not be provided to such
Holders of Securities. For the purpose of this Section, the term "default" means
any event which is, or after notice or lapse of time or both would become, an
Event of Default with respect to Securities of such series.

        6.3    CERTAIN RIGHTS OF TRUSTEE. Subject to the provisions of
Section 6.1:

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

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

               (c)    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 upon an Officers' Certificate;



                                       39
<PAGE>   41

               (d)    before the Trustee acts or refrains from acting, the
Trustee may consult with counsel and the advice of such counsel shall be full
and complete authorization and protection in respect of any action taken,
suffered or omitted by it hereunder in good faith and in reliance thereon;

               (e)    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;

               (f)    prior to the occurrence of an Event of Default hereunder
and after the curing or waiving of all Events of Default, the Trustee shall not
be bound to make any investigation into the facts or matters stated in any
resolution, Officer's Certificate, other certificate, statement, instrument
opinion, report, notice, request, consent, order approval, appraisal, bond,
debenture, note, coupon, security, or other paper or document unless requested
in writing so to do by any Holder; provided that, if the payment within a
reasonable time to the Trustee of the costs, expenses or liabilities likely to
be incurred by it in the making of such investigation is, in the opinion of the
Trustee, not reasonably assured to the Trustee by the security afforded to it by
the terms of this Indenture, the Trustee may require reasonable indemnity
against such expenses or liabilities as a condition to proceeding; the
reasonable expenses of every such examination shall be paid by the Company or,
if advanced by the Trustee, shall be repaid by the Company upon demand;

               (g)    the Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through
agents or attorneys 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;

               (h)    the Trustee shall not be liable for any action taken or
omitted to be taken 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;

               (i)    the Trustee shall not be required to give any bond or
surety in respect of the performance of its power and duties hereunder;

               (j)    the Trustee shall not be bound to ascertain or inquire as
to the performance or observance of any covenants, conditions, or agreements on
the part of the Company, except as otherwise set forth herein, but the Trustee
may require of the Company full information and advice as to the performance of
the covenants, conditions and agreements contained herein and shall be entitled
in connection herewith to examine the books, records and premises of the
Company;



                                       40
<PAGE>   42

               (k)    the permissive rights of the Trustee to do things
enumerated in this Indenture shall not be construed as a duty and the Trustee
shall not be answerable for other than its negligence or willful default;

               (l)    the Trustee shall not be deemed to have actual knowledge
of an Event of Default except for (I) a default under Sections 5.1(a) or 5.1(b)
hereof, or (ii) any other event of which the Trustee has "actual knowledge" and
which event with the giving of notice or the passage of time or both, would
constitute an Event of Default under this Indenture or event unless specifically
notified in writing of such event by the Company or any Holder; the term "actual
knowledge" means the actual fact or statement of knowing, without any duty to
make any investigation with regard thereto;

               (m)    the rights, privileges, protections, immunities and
benefits given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each
of its capacities hereunder, and to each agent, custodian and other Person
employed to act hereunder; and

               (n)    the Trustee may request that the Company deliver an
Officers' Certificate setting forth the names of individuals and/or titles of
officers authorized at such time to take specified actions pursuant to this
Indenture, which Officers' Certificate may be signed by any person authorized
to sign and Officers' Certificate, including any person specified as so
authorized in any such certificate previously delivered and not superseded.

        6.4    NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES. The
recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and the Trustee assumes no responsibility for their correctness. The Trustee
makes no representations as to the validity or sufficiency of this Indenture or
of the Securities. Neither the Trustee nor any Authenticating Agent shall be
accountable for the use or application by the Company of Securities or the
proceeds thereof.

        6.5    MAY HOLD SECURITIES. The Trustee, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities or warrants to purchase
Securities and, subject to Sections 6.8 and 6.13, may otherwise deal with the
Company with the same rights it would have if it were not Trustee, Paying Agent,
Security Registrar or such other agent.

        6.6    MONEY HELD IN TRUST. Money held by the Trustee or any Paying
Agent in trust hereunder need not be segregated from other funds except to the
extent required by law. The Trustee or any Paying Agent shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company.

        6.7    COMPENSATION AND REIMBURSEMENT. The Company agrees

               (a)    to pay to the Trustee from time to time reasonable
compensation 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);

               (b)    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 its negligence or bad faith;
and

               (c)    to indemnify the Trustee for, and to hold it harmless
against, any loss, damage, claim, liability or expense incurred without
negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration of the trust or trusts hereunder,



                                       41
<PAGE>   43

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. The costs and expenses of enforcing this right to
indemnification shall also be paid by the Company.

        As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of, premium, if any, or interest, if any,
on particular Securities.

        When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 5.1(d) or Section 5.1(e), the expenses
(including the reasonable charges and expenses of its counsel) 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.

        The provisions of this Section shall survive the termination of this
Indenture.

        6.8    DISQUALIFICATION; CONFLICTING INTERESTS. If the Trustee has or
shall acquire any conflicting interest within the meaning of the Trust Indenture
Act, the Trustee shall comply with the relevant provisions thereof.

        6.9    CORPORATE TRUSTEE REQUIRED; ELIGIBILITY. There shall at all times
be a Trustee hereunder which shall be a Person that is eligible pursuant to the
Trust Indenture Act to act as such and has a combined capital and surplus of at
least $50,000,000. If such Person publishes reports of condition at least
annually, pursuant to law or to the requirements of its supervising or examining
authority, then for the purposes of this Section, 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 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.

        6.10   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 6.11.

               (b)    The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If the instrument of acceptance by a successor Trustee required by
Section 6.11 shall not have been delivered to the resigning 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 with respect to the Securities of such series.

               (c)    The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series, delivered to the Trustee and to
the Company.

               (d)    If at any time:



                                       42
<PAGE>   44

                             (i)    the Trustee shall fall to comply with
Section 6.8 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

                             (ii)   the Trustee for a series shall cease to be
eligible under Section 6.9 and shall fail to resign after written request
therefor by the Company or by any Holder of Securities of such series, or

                             (iii)  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 its property or affairs for the purpose of
rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (ii) subject to Section 5.14, 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.

               (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
each successor Trustee or Trustees shall comply with the applicable requirements
of Section 6.11. 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 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 6.11, 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 6.11, 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.

               (f)    The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
by giving notice of such event to all Holders of Securities of such series as
provided by Section 1.6. Each notice shall include the name of the



                                       43
<PAGE>   45

successor Trustee with respect to the Securities of such series and the address
of its Corporate Trust office.

        6.11   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 its charges, 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 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 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



                                       44
<PAGE>   46

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.

        6.12   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 into which the Trustee shall be a party, or any corporation
succeeding to all or substantially all the corporate 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.
In case any Securities shall have been authenticated, but not delivered, by the
Trustee then in office, any successor by merger, conversion or consolidation to
such authenticating Trustee may adopt such authentication and deliver the
Securities so authenticated with the same effect as if such successor Trustee
had itself authenticated such Securities.

        6.13   PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY. If and when
the Trustee shall be or become a creditor of the Company (or any other obligor
upon the Securities or the Coupons, if any), 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).

        6.14   APPOINTMENT OF AUTHENTICATING AGENT. The Trustee 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 or upon exchange,
registration of transfer or partial redemption thereof or pursuant to Section
3.6, and Securities so authenticated shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if authenticated
by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by, an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation having a combined capital and
surplus of not less than the equivalent of $50,000,000 and subject to
supervision or examination by Federal or State authority or the equivalent
foreign authority, in the case of an Authenticating Agent who is not organized
and doing business under the laws of the United States of America, any State
thereof or the District of Columbia. 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.



                                       45
<PAGE>   47

        Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of 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 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 mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders Registered
Securities, if any, of the series with respect to which such Authenticating
Agent will serve, as their names and addresses appear in the Security Register.
Any successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

        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 and issued under
the within-mentioned Indenture.

        If all of the Securities of a series may not be originally issued at one
time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment or other place
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 1.2 and need not be accompanied by an

               (c)    to add any additional Events of Default with respect to
all or any series of the Securities (and, if such Event of Default is applicable
to less than all series of Securities specifying the series to which such Event
of Default is applicable);

               (d)    to add to or change any of the provisions of this
Indenture to such extent as shall be necessary to facilitate the issuance of
Securities in bearer form, registrable or not registrable as to principal, and
with or without interest coupons; to change or eliminate any restrictions on the
payment of principal of or any premium or interest on Bearer Securities, to

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

               (f)    to establish the form or terms of Securities of any series
as permitted by Sections 2.1 and 3.1;

provision herein which may be defective or inconsistent with any other provision
herein, or to make any other provisions with respect to matters or questions
arising under this Indenture; provided such other provisions as may be made
shall not adversely affect the interests of the Holders of Securities of any
series in any material respect.

        9.2    SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS. With the consent
of the Holders of not less than a majority in principal amount of the
Outstanding Securities of all series affected by such supplemental indenture
(acting as one class), by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by or pursuant to a Board Resolution, and
the Trustee may enter into an indenture or indentures supplemental hereto for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the



                                       50
<PAGE>   52

provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities of such series under this Indenture; provided, however,
that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby,

               (a)    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 that would be due and payable upon a
declaration of acceleration of the Maturity thereof pursuant to Section 5.2, or
change any Place of Payment where, or the coin or currency in which, any
Security or any premium or the interest thereon is payable, or impair the right
to institute suit for the enforcement of any such payment on or after the Stated

Date).

               (b)    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.

               (c)    change any obligation of the Company, with respect to
Outstanding Securities of a series, to maintain an office or agency in the
places and for the purposes specified in Section 10.2 for such series, or

               (d)    modify any of the provisions of this Section or Section
5.13 except to increase any such percentage or to provide with respect to any

percentage of the aggregate principal amount of Outstanding Securities of such
series (which provision may be made pursuant to Section 3.1 without the consent
of any Holder) 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 with respect to changes in
the references to the Trustee and concomitant changes in this Section, or the
deletion of this proviso, in accordance with the requirements of Sections
6.11(b) and 9.1(7).

        For purposes of this Section 9.2, if the Securities of any series are
issuable upon the exercise of warrants, each holder of an unexercised and
unexpired warrant with respect to such series shall be deemed to be a Holder of
Outstanding Securities of such series in the amount issuable upon the exercise
of such warrant. For such purposes, the ownership of any such warrant shall be
determined by the Company in a manner consistent with customary commercial
practices. The Trustee for such series shall be entitled to rely on an Officer's
Certificate as to the principal amount of Securities of such series in respect
of which consents shall have been executed by holders of such warrants.

        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



                                       51
<PAGE>   53

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 supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

        9.3    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 6.1) 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,
immunities or liabilities under this Indenture or otherwise.

        9.4    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 shall be bound thereby.

        9.5    CONFORMITY WITH TRUST INDENTURE ACT. Every supplemental indenture
executed pursuant to this Article shall conform to the requirements of the Trust
Indenture Act.

        9.6    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.

                                    ARTICLE X
                                    COVENANTS

        10.1   PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST. The Company covenants
and agrees for the benefit of each series of Securities and Coupons, if any,
that it will duly and punctually pay the principal of (and premium, if any, on)
each of the Securities and Coupons, if any, of that series, and the interest, if
any, which shall have accrued thereon, in accordance with the terms of the
Securities and Coupons, if any, of such series and this Indenture.

        10.2   MAINTENANCE OF OFFICE OR AGENCY. If Securities of a series are
issuable only as Registered Securities, until all the Securities of each such
series shall have been paid or payment



                                       52
<PAGE>   54
 thereof provided for, 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 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,
until all the Securities of each such series shall have been paid or payment
thereof provided for, 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 this 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 10.4);
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 in Europe, 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 the Holders 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 10.4) at the London office of the Trustee (or an agent with a London
office appointed by the Trustee and acceptable to the Company), and the Company
hereby appoints the same as its agent to receive such respective presentations,
surrenders, notices and demands. Presentation of Coupons for payment or other
demands for payment of Bearer Securities must be made outside the United States,
and 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
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 10.4) shall be made at the office of the Company's Paying Agent in
The City of New York, if (but only if) (i) despite the




                                       53

<PAGE>   55

appointment of Paying Agents outside the United States, payment of the full
amount of such principal, premium, interest or additional amounts, as the case
may be, at the offices of all such Paying Agents maintained for the purpose by
the Company in accordance with this Indenture is illegal or effectively
precluded by exchange controls or other similar restrictions, (ii) such payment
is then permitted by applicable laws and (iii) in appointing a Paying Agent in
The City of New York, the Company would not suffer any fiscal or other sanction
under applicable laws as a result of such appointment or of any payment being
made through such Paying Agent.

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

        10.3   MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST. If the Company
shall at any time act as its own Paying Agent with respect to any series of
Securities, it will, on or before each due date of the principal of (and
premium, if any) or interest, if any, 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) or interest, if any,
so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of its
action or failure so to act.

        Whenever the Company shall have one or more Paying Agents "or any series
of Securities, it will, at or prior to the opening of business on each due date
of the principal of (and premium, if any) or interest, if any, on any Securities
of that series, deposit with a Paying Agent a sum sufficient to pay the
principal (and premium, if any) or interest, if any, so becoming due, 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 will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will (i) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (ii) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, and 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.

        Anything in this Section 10.3 to the contrary notwithstanding, 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



                                       54
<PAGE>   56

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
money.

        Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest, if any, on any Security of any series and remaining unclaimed
for two years after such principal (and premium, if any) or interest has become
due and payable shall be paid to the Company, or (if then held by the Company)
shall be discharged from such trust; and the Holder of such Security and
Coupons, if any, 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, shall at
the expense and at the written direction of the Company cause to be published
once, in a newspaper published in the English language, customarily published on
each Business Day and of general circulation in The City of New York, notice
that such money remains unclaimed and that, after a date specified herein, which
shall not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Company.

        10.4   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 and subject to the conditions set forth 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 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 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 (as defined in the Securities) 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



                                       55
<PAGE>   57

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 an Officer's Certificate furnished pursuant to this
Section.

        10.5   STATEMENT AS TO COMPLIANCE. On or before March 31 of each year
following the date hereof, the Company shall deliver to the Trustee a
certificate of the principal executive officer, principal financial officer or
principal accounting officer of the Company, stating whether or not to the best
knowledge of such officer 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 such officer may have knowledge.

        10.6   CALCULATION OF ORIGINAL ISSUE DISCOUNT.

               The Company shall file with the Trustee promptly at the end of
each calendar year (i) a written notice specifying the amount of original issue
discount (including daily rates and accrual periods) accrued on Outstanding
Securities as of the end of such year and (ii) such other specific information
relating to such original issue discount as may then be relevant under the
Internal Revenue Code of 1986, as amended from time to time.

                                   ARTICLE XI
                            REDEMPTION OF SECURITIES

        11.1   APPLICABILITY OF ARTICLE. Securities (including any Coupons) 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 3.1 for Securities (including any Coupons of any series)
in accordance with this Article.

        11.2   ELECTION TO REDEEM; NOTICE TO TRUSTEE. The election of the
Company to redeem any Securities (including any Coupons) shall be evidenced by a
Board Resolution or by an action taken pursuant to a Board Resolution. In case
of any redemption at the election of the Company of less than all the Securities
(including any Coupons) of any series, the Company shall, at least 60 days prior
to the Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date and of
the principal amount of Securities (including any Coupons) of such series to be
redeemed. In the case of any redemption of Securities (including any Coupons)
prior to the expiration of any restriction on such redemption provided in the
terms of such Securities (including any Coupons) or elsewhere in this Indenture,
the Company shall furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction.

        11.3   SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED. If less than
all the Securities (including any Coupons) of any series are to be redeemed, the
particular Securities (including any Coupons) to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities (including any Coupons) of such series not previously
called for redemption, by such method as the Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of portions
(equal to the minimum authorized denomination for Securities(including any
Coupons) of that series or any integral multiple thereof) of the principal
amount of Securities (including any Coupons) of such



                                       56
<PAGE>   58

series of a denomination larger than the minimum authorized denomination for
Securities (including any Coupons) of that series.

        In any case where Securities (including any Coupons) of such series are
registered in the same name, the Trustee in its discretion may treat the
aggregate principal amount so registered as if it were represented by one
Security of such series. If the Securities of any series (including any Coupons)
to be redeemed consist of Securities having different Stated Maturities or
different rates of interest (or methods of computing interest), then the Company
may, in the written notice delivered to the Trustee pursuant to Section 11.2,
direct that the Securities (including any Coupons) of such series to be redeemed
shall be selected from among groups of such Securities having specified Stated
Maturities or rates of interest (or methods of computing interest) and the
Trustee shall thereafter select the particular Securities (including any
Coupons) to be redeemed in the manner set forth above from among the groups of
such Securities so specified.

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

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

        11.4   NOTICE OF REDEMPTION. Notice of redemption shall be given not
less than 30 nor more than 60 days prior to the Redemption Date, to each Holder
of Securities to be redeemed, as provided in Section 1.6.

        Each such notice of redemption shall specify the Redemption Date, the
Redemption Price, the Place or Places of Payment, that the Securities of such
series are being redeemed at the option of the Company pursuant to provisions
contained in the terms of the Securities of such series or in a supplemental
indenture establishing such series, if such be the case, together with a brief
statement of the facts permitting such redemption, that on the Redemption Date
the Redemption Price will become due and payable upon each Security redeemed,
that payment will be made upon presentation and surrender of the applicable
Securities, that all Coupons, if any, maturing subsequent to the date fixed for
redemption shall be void, that any interest accrued to the Redemption Date will
be pa id as specified in said notice, and that on and after said Redemption Date
any interest thereon or on the portions thereof to be redeemed will cease to
accrue. If less than all the Securities of any series are to be redeemed the
notice of redemption shall specify the numbers of the Securities of such series
to be redeemed, and, if only Bearer Securities of any series are to be redeemed,
and if such Bearer Securities may be exchanged for Registered Securities, the
last date on which exchanges of Bearer Securities for Registered Securities not
subject to redemption may be made. In case any Security of any series is to be
redeemed in part only, the notice of redemption shall state the portion of the
principal amount thereof to be redeemed and shall state that on and after the
Redemption Date, upon surrender of



                                       57
<PAGE>   59

such Security and any Coupons appertaining thereto, a new Security or Securities
of such series in principal amount equal to the unredeemed portion thereof and
with appropriate Coupons will be issued, or, in the case of Registered
Securities providing appropriate space for such notation, at the option of the
Holders, the Trustee, in lieu of delivering a new Security or Securities as
aforesaid, may make a notation on such Security of the payment of the redeemed
portion thereof.

        Notice of redemption of Securities and Coupons, if any, 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.

        11.5   DEPOSIT OF REDEMPTION PRICE. On or before the opening of business
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 10.3) an amount of money 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 and Coupons, if
any, which are to be redeemed on that date.

        11.6   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, if any) 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, if any, 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 10.2) and, unless otherwise specified as
contemplated by Section 3.1, only upon presentation and surrender of Coupons for
such interest, and provided, further, that, unless otherwise specified as
contemplated by Section 3.1, 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 3.7.

        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



                                       58
<PAGE>   60

be payable only at an office or agency located outside the United States (except
as otherwise provided in Section 10.2) and, unless otherwise specified as
contemplated by Section 3.1, 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 (or, in the case of any Original Issue Discount Securities, the
Security's Yield to Maturity).

        11.7   SECURITY REDEEMED IN PART. Any Security (including any Coupons
appertaining thereto) 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 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 (including any
Coupons appertaining thereto) without service charge, a new Security (including
any Coupons appertaining thereto) or Securities (including any Coupons
appertaining thereto) of the same series and Stated Maturity and 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 (including any Coupons appertaining thereto) so surrendered.

                                   ARTICLE XII
                                  SINKING FUNDS

        12.1    APPLICABILITY OF ARTICLE. The provisions of this Article shall
be applicable to any sinking fund for the retirement of Securities (including
any Coupons) of a series except as otherwise specified as contemplated by
Section 3.1 for Securities (including any Coupons) of such series.

        The minimum amount of any sinking fund payment provided for by the terms
of Securities (including any Coupons) of any series is herein referred to as a
"mandatory sinking fund payment", and any payment in excess of such minimum
amount provided for by the terms of Securities (including any Coupons) of any
series is herein referred to as an "optional sinking fund payment". If provided
for by the terms of Securities (including any Coupons) of any series, the cash
amount of any sinking fund payment may be subject to reduction as provided in
Section 12.2. Each sinking fund payment shall be applied to the redemption of
Securities (including any Coupons) of any series as provided for by the terms of
Securities (including any Coupons) of such series.

        12.2   SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES. The
Company (1) may deliver Outstanding Securities (including any Coupons) of a
series (other than any previously called for redemption) and (2) may apply as a
credit Securities (including any Coupons) of a series which have been redeemed
(or called for redemption and for which the Redemption Price, together with
accrued interest, if any, has been deposited pursuant to Section 11.5), either
at the election of the Company pursuant to the terms of such Securities
(including any Coupons) or through the application of permitted optional sinking
fund payments



                                       59
<PAGE>   61

pursuant to the terms of such Securities (including any Coupons), in each case
in satisfaction of all or any part of any sinking fund payment with respect to
the Securities (including any Coupons) of such series required to be made
pursuant to the terms of such Securities (including any Coupons) as provided for
by the terms of such series; provided that such Securities (including any
Coupons) have not been previously so credited. Such Securities (including any
Coupons) shall be received and credited for such purpose by the Trustee at the
Redemption Price specified in such Securities (including any Coupons) for
redemption through operation of the sinking fund and the amount of such sinking
fund payment shall be reduced accordingly.

        12.3   REDEMPTION OF SECURITIES FOR SINKING FUND. Not less than 60 days
prior to each sinking fund payment date for any series of Securities (including
any Coupons), the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities (including any Coupons) of that
series pursuant to Section 12.2 and the optional amount, if any, to be added in
cash to the next ensuing mandatory sinking fund payment, and will also deliver
to the Trustee any Securities (including any Coupons) to be so delivered. If
such Officers' Certificate shall specify an optional amount to be added in cash
to the next ensuing mandatory sinking fund payment, the Company shall thereupon
be obligated to pay the amount therein specified. Not less than 30 days before
each such sinking fund payment date the Trustee shall select the Securities
(including any Coupons) to be redeemed upon such sinking fund payment date in
the manner specified in Section 11.3 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 11.4. Such notice having been duly given, the redemption of
such Securities (including any Coupons) shall be made upon the terms and in the
manner stated in Sections 11.6 and 11.7.

                                  ARTICLE XIII
                        MEETINGS OF HOLDERS OF SECURITIES

        13.1    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,

<PAGE>   62

               (b)    In case at any time the Company, by or pursuant to a Board
Resolution, or the Holders of at least 10% in principal amount of the
Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified in
Section 13.1, by written request setting forth in reasonable detail the 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, Chicago, Illinois or in
London, England for such meeting and may call such meeting for such purposes by
giving notice thereof as provided in subsection (a) of this Section.

        13.3   PERSONS ENTITLED TO VOTE AT MEETINGS. To been titled to vote at
any meeting of Holders of Securities of any series, a Person shall be (1) a
Holder of one or more Outstanding Securities of such series, or (2) a Person

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

        13.4   QUORUM; ACTION. The Persons entitled to vote a majority in
principal amount of the Outstanding Securities of a series shall constitute a

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

the adjournment of such adjourned meeting. Notice of the reconvening of any
adjourned meeting shall be given as provided in Section 13.2(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. Subject to the foregoing, at
the reconvening of any such further adjourned meeting, the Persons entitled to
vote 25% in aggregate principal amount of the Outstanding Securities of such
series shall constitute a quorum for the taking of any action set forth in the
notice of the original meeting. Notice of the reconvening of an adjourned
meeting which was adjourned for lack of a quorum shall state expressly the
percentage, as provided above, of the principal amount of the Outstanding
Securities of such series which shall constitute a quorum.

        Except as limited by the proviso to Section 9.2, and subject to the
provisions described in the next succeeding paragraph, 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 lesser of (i) the
Holders of a majority in principal amount of the Outstanding Securities of that
series and (ii) 66-2/3% in principal amount of Outstanding Securities of such

<PAGE>   63

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

of (i) the Holders of such specified percentage in principal amount of the
Outstanding Securities of that series and (ii) a majority in principal amount of
Outstanding Securities of such series represented and voting at such meeting or
adjourned meeting. 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.

        With respect to any consent, waiver or other action which this Indenture
expressly provides may be given by the Holders of a specified percentage of
Outstanding Securities of all series affected thereby (acting as one class),
only the principal amount of Outstanding Securities of any series represented at
a meeting or adjourned meeting duly reconvened at which a quorum was present,
held in accordance with this Section, and voting in favor of such action, shall
be counted for purposes of calculating the aggregate principal amount of
Outstanding Securities of all series affected thereby favoring such action.

        13.5   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 1.4
and the appointment of any proxy shall be proved in the manner specified in
Section 1.4 or by having the signature of the person executing the proxy
witnessed or guaranteed by any trust company, bank or banker authorized by
Section 1.4 to certify to the holder 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 1.4 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 13.2(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.



                                       62
<PAGE>   64

               (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 13.2 at which a quorum is present may be adjourned
from time to time by Persons entitled to vote a majority in principal amount of
the Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

        13.6   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 13.2
and, if applicable, Section 13.4. 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 XIV
         IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS

        14.1    IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS.
No recourse shall be had for the payment of the principal of (or premium, if
any, on) or interest, if any, on, any Security of any series (or any Coupon
appertaining thereto), or any part thereof, or for any claim based thereon or
otherwise in respect thereof, or of the indebtedness represented thereby, or
upon any obligation, covenant or agreement of this Indenture, against any
incorporator, direct or indirect stockholder, officer or director, as such,
past, present or future, of the Company, or of any successor corporation, either
directly or through the Company or any successor corporation, whether by virtue
of any constitutional provision, statute or rule of law, or by the enforcement
of any assessment or penalty or otherwise; it being expressly agreed and
understood that this Indenture and all the Securities of all series (and any
Coupons appertaining thereto) are solely corporate obligations, and that no
personal liability whatsoever shall attach to, or be incurred by,



                                       63
<PAGE>   65

any incorporator, direct or indirect stockholder, officer or director, as such,
past, present or future, of the Company or of any successor corporation, either
directly or through the Company or any successor corporation, because of the
incurring of the indebtedness hereby authorized or under or by reason of any of
the obligations, covenants, promises or agreements contained in this Indenture
or in any of the Securities of any series (or any Coupons appertaining thereto)
or to be implied here from or therefrom, and that all liability, if any, of that
character against every such incorporator, stockholder, officer and director is,
by the acceptance of the Securities of any series (or any Coupons appertaining
thereto), and as a condition of, and as part of the consideration for, the
execution of this Indenture and the issue of the Securities (and any Coupons
appertaining thereto), expressly waived and released.

                                   ARTICLE XV
                                  SUBORDINATION

        15.1    AGREEMENT TO SUBORDINATE. Anything to the contrary herein
notwithstanding, the Company covenants and agrees, and each Holder of Securities
of any series (or any Coupons appertaining thereto) by acceptance thereof
likewise covenants and agrees, that the indebtedness represented by the
Securities of such series (and any Coupons appertaining thereto) and the payment
of the principal of (and premium, if any, on) and interest, if any, on each and
all of the Securities of such series (and any Coupons appertaining thereto)
shall be subordinate and junior in right of payment, to the extent and in the
manner hereinafter set forth, to the prior payment in full of all Senior Debt
(as defined below), whether outstanding at the date hereof or incurred after the
date hereof, but shall in all respects rank pari passu with all other
Subordinated Debt (as defined below).

        15.2   NO PAYMENTS TO HOLDERS OF SECURITIES IN CERTAIN CIRCUMSTANCES.

               (a)    In the event of any sale under or in accordance with any
judgment or decree rendered in any proceeding by or on behalf of any Holder of
Securities (or any Coupons appertaining thereto) or in the event of any
distribution, division or application, partial or complete, voluntary or
involuntary, by operation of law or otherwise, of all or any part of the assets
of the Company, or the proceeds thereof, to creditors of the Company occurring
by reason of any liquidation, dissolution or winding up of the Company, or in
the event of any receivership, insolvency, bankruptcy, liquidation,
readjustment, reorganization or other similar proceeding relative to the Company
or its debts or properties, then in any such event the holders of any and all
Senior Debt shall be preferred in the payment of their claims over the Holders
of Securities (or any Coupons appertaining thereto), and such Senior Debt shall
be first paid and satisfied in full before any payment or distribution of any
kind or character, whether in cash, property or securities (other than
securities which are subordinate and junior in right of payment to the payment
of all Senior Debt which may at the time be outstanding), shall be made upon the
Securities (or any Coupons appertaining thereto); and in any such event any

<PAGE>   66

indebtedness evidenced by the Securities (or any Coupons appertaining thereto),
or any renewals or extensions thereof, shall be paid over to the holders of such
Senior Debt, pro rata, for application in payment thereof unless and until such
Senior Debt shall have been paid and satisfied in full; and

               (b)    In the event that pursuant to the provisions hereof any
Security is declared or becomes due and payable before its Stated Maturity
because of an occurrence of an Event of Default (under circumstances when
paragraph (a) of this Section 15.2 shall not be applicable), no amount shall be
paid by the Company in respect of the principal of or interest, if any, on the
Securities (or any Coupons appertaining thereto) in excess of current interest
payments as provided herein, except at the Stated Maturity thereof or in
accordance with any regular mandatory prepayments as contemplated by Section 3.1
for Securities of any series (or any Coupons appertaining thereto) (all subject
to paragraph (a) of this Section 15.2), unless and until all Senior Debt
outstanding at the time such Security so becomes due and payable because of any
such event shall have been paid in full or payment thereof shall have been
provided for in a manner satisfactory to the holders of such outstanding Senior
Debt; and

               (c)    without limiting the effect of any of the other provisions
of this Article XV, during the continuance of any default with respect to any
Senior Debt, no payment of principal, sinking fund, interest or premium shall be
made on or with respect to the indebtedness evidenced by the Securities (or any
Coupons appertaining thereto) or any renewals or extensions hereof, if either
(l) notice of such default in writing or by telegram has been given to the
Company by any holder or holders of any Senior Debt, provided that judicial
proceedings shall be commenced with respect to such default within 120 days
thereafter or (2) judicial proceedings shall be pending in respect of such
default.

        The Company covenants and agrees, for the benefit of each and every
present and future holder of Senior Debt, that in the event that pursuant to the
provisions hereof any Security is declared or becomes due and payable because of
an occurrence of an Event of Default, then each holder of any Senior Debt then
outstanding shall have the right to declare immediately due and payable on
demand all or any part of such Senior Debt owing and payable to such holder,
regardless of any other maturity or terms of said Senior Debt; and if and when
any such default has occurred, or any notice of default under the terms hereof
may be served upon the Company, then in each such event the Company shall and
hereby agrees that it will immediately notify the holders of the Senior Debt of
such default or notice thereof, as the case may be.

        15.3   PAYMENTS BY TRUSTEE OR HOLDERS OF SECURITIES TO HOLDERS OF SENIOR
DEBT. In the event that any payment by, or distribution of assets of, the
Company of any kind or character, whether in cash, property or securities, shall
be received by the Trustee or the Holders of Securities (or any Coupons
appertaining thereto) before all Senior Debt is paid in full, contrary to the
provisions of Section 15.2, such payment or distribution shall be paid over to
the holders of such Senior Debt or their representative or representatives or to
the trustee or trustees under any indenture under which any instruments
evidencing any of such Senior Debt may have been issued, ratably as aforesaid,
for application to the payment of all Senior Debt remaining unpaid



                                       65
<PAGE>   67

until all such Senior Debt shall have been paid in full, after giving effect to
any concurrent payment or distribution (or provision therefor) to the holders of
such Senior Debt.

        15.4   SUBROGATION. Subject to the payment in full of all Senior Debt,
the Holders of Securities land any Coupons appertaining thereto) shall be
subrogated to the rights of the holders of Senior Debt to receive payments or
distributions of cash, property or securities of the Company applicable to the
Senior Debt until all amounts owing on the Securities (and any Coupons
appertaining thereto) shall be paid in full, and, as between the Company, its
creditors other than holders of Senior Debt, and the Holders of Securities (and
any Coupons appertaining thereto), no such payment or distribution made to the
holders of Senior Debt by virtue of this Article XV which otherwise would have
been made to the Holders of Securities (and any Coupons appertaining thereto)
shall be deemed to be a payment by the Company on account of the Senior Debt, it
being understood that the provisions of this Article XV are and are intended
solely for the purpose of defining the relative rights of the Holders of
Securities (and any Coupons appertaining thereto), on the one hand, and the
holders of Senior Debt, on the other hand.

        15.5   OBLIGATION OF COMPANY UNCONDITIONAL. Nothing herein shall impair,
as between the Company and the Holders of Securities (and any Coupons
appertaining thereto), the right of the Holder of any Security or any Coupon,
which is absolute and unconditional, to receive payment of the principal (and
premium, if any) and interest, if any, thereon in accordance with their terms,
or shall prevent the Trustee or any Paying Agent from applying any moneys
deposited with it hereunder to the payment of principal of (or premium, if any)
or interest, if any, on any of the Securities (or any Coupons appertaining
thereto), in each case except as otherwise provided in this Article XV, nor
shall anything herein prevent any Holder of Securities (or any Coupons
appertaining thereto) from exercising all remedies otherwise permitted by
applicable law or hereunder upon default hereunder, subject to the rights, if
any, of holders of Senior Debt as herein provided. Each and every holder of
Securities (or any Coupons appertaining thereto) by acceptance thereof shall
undertake and agree for the benefit of each holder of Senior Debt to execute,
verify, deliver and file any proofs of claim, consents, assignments or other
instruments which any holder of Senior Debt may at any time require in order to
prove and realize upon any rights or claims pertaining to the Securities (or any
Coupons appertaining thereto) and to effectuate the full benefit of the
subordination contained in this Article XV.

        Upon any payment or distribution of assets of the Company referred to in
this Article XV, the Trustee and the Holders of Securities (or any Coupons
appertaining thereto) shall be entitled to rely upon any order or decree made by
any court of competent jurisdiction in which any such dissolution, winding up,
liquidation or reorganization proceeding affecting the affairs of the Company is
pending or upon a certificate of the liquidating trustee or agent or other
person making any payment or distribution to the Trustee or to the Holders of
Securities (or any Coupons appertaining thereto) for the purpose of ascertaining
the persons entitled to participate in such payment or distribution, the holders
of the Senior Debt and other indebtedness of the Company, the amount thereof or
payable thereon, the amount paid or distributed thereon and all other facts
pertinent thereto or to this Article XV. In the event that the Trustee
determines, in good faith, that further evidence is required with respect to the
right of any person as a holder of



                                       66
<PAGE>   68

Senior Debt to participate in any payment or distribution pursuant to this
Article XV, the Trustee may request such person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Debt held by
such person, as to the extent to which such person is entitled to participate in
such payment or distribution, and as to other facts pertinent to the rights of
such person under this Article XV, and if such evidence is not furnished, the
Trustee may defer any payment to such person pending judicial determination as
to the right of such person to receive such payment.

        15.6   PAYMENTS ON SECURITIES PERMITTED. Nothing contained in this
Article XV or elsewhere in this Indenture, or in any of the Securities (or any
Coupons appertaining thereto), shall (a) affect the obligation of the Company to
make, or prevent the Company from making, at any time except in the event of any
event specified in Section 15.2, payments at any time of principal of (or
premium, if any) or interest, if any, on the Securities of any series (or any
Coupons appertaining thereto) or of any sinking fund payments with respect to
the Securities of any series, or (b) prevent the application by the Trustee or
any Paying Agent of any moneys held by the Trustee or such Paying Agent in trust
for the benefit of the holders of Securities of any series (and any Coupons
appertaining thereto) as to which notice of redemption shall have been mailed or
published at least once prior to the happening of an event specified in
paragraph (b) or (c) of Section 15.2 to the payment of or on account of the
principal of (and premium, if any on) and interest, if any, on such Securities
(and any Coupons appertaining thereto), or (c) prevent the application by the
Trustee or any Paying Agent of any moneys deposited prior to the happening of
any event specified in paragraph (b) or (c) of Section 15.2 with the Trustee or
such Paying Agent in trust for the purpose of paying a specified installment or
installments of interest on the Securities of any series (or any Coupons
appertaining thereto), to the payment of such installments of interest on the
Securities of any series (or any Coupons appertaining thereto).

        15.7   EFFECTUATION OF SUBORDINATION BY TRUSTEE. Each holder of
Securities (or any Coupons appertaining thereto), by his acceptance thereof,
authorizes and directs the Trustee in his behalf to take such action as may be
necessary or appropriate to effectuate the subordination provided in this
Article XV and appoints the Trustee his attorney-in-fact for any and all such
purposes.

        The Trustee shall not be deemed to owe any fiduciary duty to the holders
of Senior Debt and, with respect to the holders of Senior Debt, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article XV, and no implied covenants or
obligations with respect to the holders of Senior Debt shall be read into this
Indenture against the Trustee. Subject to the provisions of Section 6.1, the
Trustee shall not be liable to any holder of Senior Debt if it shall mistakenly
pay over or deliver to holders of Securities (or any Coupons appertaining
thereto), the Company or any other person moneys or assets to which any holder
of Senior Debt shall be entitled by virtue of this Article XV or otherwise.

        15.8   KNOWLEDGE OF TRUSTEE. Notwithstanding the provisions of this
Article XV or any other provisions of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment of moneys to or by the



                                       67
<PAGE>   69

Trustee, or the taking of any other action by the Trustee, unless and until the
Trustee shall have received written notice thereof from the Company, any Holder,
any Paying Agent or the holder or representative of any class of Senior Debt.

        Prior to the receipt of any such written notice, the Trustee, subject to
the provisions of Section 6.1, shall be entitled in all respects to assume that
no such facts exist; provided, that if on a date not less than one day prior to
the date upon which by the terms hereof any such moneys may become payable for
any purpose (including, without limitation, the payment of the principal of or
interest, if any, on any Securities (or any Coupons appertaining thereto)), the
Trustee shall not have received with respect to such moneys the notice provided
for in this Section 15.8, then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive such
moneys and to apply the same to the purpose for which they were received, and
shall not be affected by any notice to the contrary which may be received by it
on or after such prior date.

        15.9   TRUSTEE MAY HOLD SENIOR DEBT. The Trustee shall be entitled to
all the rights set forth in this Article XV with respect to any Senior Debt at
the time held by it, to the same extent as any other holder of Senior Debt, and
nothing in Section 6.13 or elsewhere in this Indenture shall deprive the Trustee
of any of its rights as such holder.

        15.10  RIGHTS OF HOLDERS OF SENIOR DEBT NOT IMPAIRED. No right of any
present or future holder of any Senior Debt to enforce the subordination herein
shall at any time or in any way be prejudiced or impaired by any act or failure
to act on the part of the Company or by any non-compliance by the Company with
the terms, provisions and covenants of this Indenture, regardless of any
knowledge thereof any such holder may have or be otherwise charged with.

        15.11  RIGHTS AND OBLIGATIONS SUBJECT TO POWER OF COURT. The right of
the holders of Senior Debt and the obligations of the Trustee and the Holders of
Securities (and any Coupons appertaining thereto) set forth in this Article XV
are subject to the power of a court of competent jurisdiction to make other
equitable provision reflecting the rights conferred in this Indenture upon the
Senior Debt and the holders thereof with respect to the Securities (and any
Coupons appertaining thereto) and the holders thereof by a plan of
reorganization under applicable bankruptcy law.

        15.12  DEFINITIONS. The following terms shall have the following
meanings:

        Debt.
