                                                                               8

to such resolution of the Board of Directors or in any such indenture
supplemental hereto.

            SECTION 2.4 Authentication and Delivery of Securities. At any time
and from time to time after the execution and delivery of this Indenture, the
Issuer may deliver Securities of any series having attached thereto appropriate
Coupons, if any, executed by the Issuer to the Trustee for authentication.
Except as otherwise provided in this Section, the Trustee shall thereupon
authenticate and deliver such Securities with Coupons, if any, to or upon the
written order of the Issuer, signed by both (a) the chairman of its Board of
Directors, its president, or the chairman of its executive committee, any vice
chairman of its Board of Directors or any vice president and (b) by its
treasurer or any assistant treasurer, without any further action by the Issuer.
In authenticating such Securities and Coupons, if any, and accepting the
additional responsibilities under this Indenture in relation to such Securities
and Coupons, if any, the Trustee shall be entitled to receive, and (subject to
Section 6.1) shall be fully protected in relying upon:

            (1)   a certified copy of any resolution or resolutions of the Board
      of Directors authorizing the action taken pursuant to the resolution or
      resolutions delivered under clause (2) below;

            (2)   a copy of any resolution or resolutions of the Board of
      Directors relating to such series, in each case certified by the Secretary
      or an Assistant Secretary of the Issuer;

            (3)   an executed supplemental indenture, if any;

            (4)   an Officers' Certificate setting forth the form and terms of
      the Securities and Coupons, if any, as required pursuant to Sections 2.1
      and 2.3, respectively and prepared in accordance with Section 12.5;

            (5)   an Opinion of Counsel, prepared in accordance with Section
      12.5, which shall state

                  (a)   that the form or forms and terms of such Securities and
            Coupons, if any, have been established by or pursuant to a
            resolution of the Board of Directors or by a supplemental indenture
            as permitted by Sections 2.1 and 2.3 in conformity with the
            provisions of this Indenture;
<PAGE>   10
                                                                               9

                  (b)   that such Securities, and Coupons, if any, when
            authenticated and delivered by the Trustee and issued by the Issuer
            in the manner and subject to any conditions specified in such
            Opinion of Counsel, will constitute valid and binding obligations of
            the Issuer;

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

                  (d)   such other matters as the Trustee may reasonably
            request.

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

            SECTION 2.5 Execution of Securities. The Securities and, if
applicable, each Coupon appertaining thereto, shall be signed on behalf of the
Issuer by the chairman of its Board of Directors, its president, or the chairman
of its executive committee, any vice chairman of its Board of Directors or any
vice president under its corporate seal attested by its secretary or any
assistant secretary. Such signatures may be the manual or facsimile signatures
of the present or any future such officers. The seal of the Issuer may be in the
form of a facsimile thereof and may be impressed, affixed, imprinted or
otherwise reproduced on the Securities and, if applicable, each Coupon
appertaining thereto. Typographical and other minor errors or defects in any
such reproduction of the seal or any such signature shall not affect the
validity or enforceability of any Security that has been duly authenticated and
delivered by the Trustee.

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

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

                                                                              10

            SECTION 2.7 Denomination and Date of Securities; Payments of
Interest. The Securities shall be issuable as Registered Securities or
Unregistered Securities in such denominations as shall be specified as
contemplated by Section 2.3. In the absence of any such specifications with
respect to the Registered Securities of any series, Registered Securities shall
be issued in denomination of U.S. $1,000 and any integral multiple thereof. In
the absence of any such specification with respect to Unregistered Securities,
Unregistered Securities shall be issued in denomination of U.S. $1,000. The
Securities shall be numbered, lettered or otherwise distinguished in such manner
or in accordance with such plan as the officers of the Issuer executing the same
may determine as evidenced by the execution and authentication thereof.

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

            The person in whose name any Registered Security of any series is
registered at the close of business on any record date applicable to a
particular series with respect to any interest payment date for such series
shall be entitled to receive the interest, if any, payable on such interest
payment date notwithstanding any transfer or exchange of such Registered
Security subsequent to the record date and prior to such interest payment date,
except if and to the extent the Issuer shall default in the payment of the
interest due on such interest payment date for such series, in which case such
defaulted interest shall be paid to the persons in whose names outstanding
Registered Securities for such series are registered at the close of business on
a subsequent record date (which shall be not less than ten business days prior
to the date of payment of such defaulted interest) established by notice given
by mail by or on behalf of the Issuer to the holders of Registered Securities
not less than 15 days preceding such subsequent record date. The term "record
date" as used with respect to any interest payment date (except a date for
payment of defaulted interest) shall mean the date specified as such in the
terms of the Registered Securities of any particular series, or, if no such date
is so specified, if such interest payment date is the first day of a calendar
month, the fifteenth day of the next preceding calendar month or, if such
interest payment date is the fifteenth day of a calendar month, the first day of
such calendar month, whether or not such record date is a Business Day.

            Any defaulted interest payable in respect of any Unregistered
Security shall be payable pursuant to such procedures as may be satisfactory to
the Trustee in such manner that there is no discrimination as between the
holders of Registered Securities and Unregistered Securities of the same series
and notice of the payment date therefore shall be given by the Trustee in the
name and at the expense of the Issuer by publication at least once in an
Authorized Newspaper. In case an Unregistered Security is surrendered for
exchange for a Registered Security after the close of business on any record
date for the payment of defaulted interest and before the opening of business on
the proposed date of payment of such defaulted interest, the Coupon appertaining
to such surrendered Unregistered Security and due for payment on such proposed
date of payment will not be surrendered with such surrendered Unregistered
Security and interest payable on such proposed date of payment will be made only
to the holder of such Coupon on such proposed date.

                                                                              11

            SECTION 2.8 Registration, Transfer and Exchange. The Issuer will
keep or cause to be kept at an office or agency to be maintained for such
purpose as provided in Section 3.2 a register or registers for each series of
Securities issued hereunder (collectively, the "Security Register") in which,
subject to such reasonable regulations as it may prescribe, it will register,
and will register the transfer of or cause the registration of the transfer of,
Registered Securities as in this Article provided.

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

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

            At the option of the Holder thereof, any Registered Security or
Registered Securities of any series may be exchanged for a Registered Security
or Registered Securities of the same series in other authorized denominations,
in an equal aggregate principal amount. Registered Securities of any series to
be exchanged shall be surrendered at an office or agency to be maintained by the
Issuer for such purpose as provided in Section 3.2, and the Issuer shall execute
and the Trustee shall authenticate and deliver in exchange therefor the
Registered Security or Registered Securities of the same series which the
Securityholder making the exchange shall be entitled to receive, bearing numbers
not contemporaneously outstanding. If the Securities of any series are issued in
both registered and unregistered form, except as otherwise specified pursuant to
Section 2.3, at the option of the Holder thereof, Unregistered Securities of any
series may be exchanged for Registered Securities of such series, maturity date
and interest rate of any authorized denominations and of a like aggregate
principal amount, upon surrender of such Unregistered Securities to be exchanged
at the office or agency of the Issuer that shall be maintained for such purpose
in accordance with Section 3.2, with, in the case of Unregistered Securities
that have Coupons attached, all unmatured Coupons and all matured Coupons in
default thereto appertaining, and upon payment, if the Issuer shall so require,
of the charges hereinafter provided. At the option of the Holder thereof, if
Unregistered Securities of any series, maturity date, interest rate and original
issue date are issued in more than one authorized denomination, except as
otherwise specified pursuant to Section 2.3, such Unregistered Securities may be
exchanged for Unregistered Securities of such series, maturity date, interest
rate and original issue date of other authorized denominations and of a like
aggregate principal amount, upon surrender of such Unregistered Securities to be
exchanged at the office or agency of the Issuer that shall be maintained for
such purpose in accordance with Section 3.2 or as specified pursuant to Section
2.3, with, in the case of Unregistered Securities that have Coupons attached,
all unmatured Coupons and all matured Coupons in default thereto appertaining,
and upon payment, if the Issuer shall so require, of the charges hereinafter
provided. Unless otherwise specified pursuant to Section 2.3, Registered
Securities of any series may not be exchanged for Unregistered Securities of
such series. Whenever any Securities and the Coupons appertaining thereto, if
any, are so surrendered for exchange, the Issuer shall

                                                                              12

execute, and the Trustee shall authenticate and deliver, the Securities and the
Coupons appertaining thereto, if any, which the Holder making the exchange is
entitled to receive.

            Notwithstanding the foregoing, in case an Unregistered Security of
any series is surrendered at any such office or agency in exchange for a
Registered Security of the same series after the close of business at such
office or agency on any record date and before the opening of business at such
office or agency on the relevant interest payment date, such Unregistered
Security shall be surrendered without the Coupon relating to such interest
payment date or proposed date of payment, as the case may be.

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

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

            The Issuer shall not be required to exchange or register a transfer
of (a) any Securities of any series for a period of 15 days next preceding the
close of business on the date of selection of Securities of such series to be
redeemed, or (b) any Securities selected, called or being called for redemption
except, in the case of any Security where public notice has been given that such
Security is to be redeemed in part, the portion thereof not so to be redeemed
and except that an Unregistered Security may be exchanged for a Registered
Security of the same series if such Registered Security is immediately
surrendered for redemption.

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

            Notwithstanding anything herein or in the terms of any series of
Securities to the contrary, neither the Issuer nor the Trustee (which shall rely
on an Officers' Certificate and an Opinion of Counsel) shall be required to
exchange any Unregistered Security for a Registered Security if such exchange
would result in adverse Federal income tax consequences to the Issuer
(including, without limitation, the inability of the Issuer to deduct from its
income, as computed for Federal income tax purposes, the interest payable on the
Unregistered Securities) under then applicable United States Federal income tax
laws.

            SECTION 2.9 Mutilated, Defaced, Destroyed, Lost and Stolen
Securities. In case any temporary or definitive Security or any Coupon
appertaining to any Security shall become mutilated, defaced or be destroyed,
lost or stolen, the Issuer in its discretion may execute, and upon the written
request of any officer of the Issuer, the Trustee shall authenticate and
deliver, a new Registered Security of the same series, bearing a number not
contemporaneously outstanding, in exchange and substitution for the mutilated or
defaced Security, or in lieu of and substitution for the Security so destroyed,
lost or stolen with Coupons corresponding to the Coupons appertaining to the
Security so mutilated, defaced, destroyed, lost or stolen, or in exchange or
substitution for the Security to which such mutilated, defaced,
<PAGE>   14
                                                                              13

destroyed, lost or stolen Coupon appertained, with Coupons appertaining thereto
corresponding to the Coupons so mutilated, defaced, destroyed, lost or stolen.
In every case the applicant for a substitute Security or Coupon shall furnish to
the Issuer and to the Trustee and any agent of the Issuer or the Trustee such
security or indemnity as may be required by them to indemnify and defend and to
save each of them harmless and, in every case of destruction, loss or theft,
evidence to their satisfaction of the destruction, loss or theft of such
Security or Coupon and of the ownership thereof.

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

            Every substitute Security or Coupon of any series issued pursuant to
the provisions of this Section by virtue of the fact that any such Security or
Coupon is destroyed, lost or stolen shall constitute an additional contractual
obligation of the Issuer, whether or not the destroyed, lost or stolen Security
or Coupon shall be at any time enforceable by anyone and shall be entitled to
all the benefits of (but shall be subject to all the limitations of rights set
forth in) this Indenture equally and proportionately with any and all other
Securities or Coupons of such series duly authenticated and delivered hereunder.
All Securities or Coupons shall be held and owned upon the express condition
that, to the extent permitted by law, the foregoing provisions are exclusive
with respect to the replacement or payment of mutilated, defaced or destroyed,
lost or stolen Securities or Coupons and shall preclude any and all other rights
or remedies notwithstanding any law or statute existing or hereafter enacted to
the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.

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

                                                                              14

            SECTION 2.11 Temporary Securities. Pending the preparation of
definitive Securities for any series, the Issuer may execute and the Trustee
shall authenticate and deliver temporary Securities for such series (printed,
lithographed, typewritten or otherwise reproduced, in each case in form
satisfactory to the Trustee). Temporary Securities of any series shall be
issuable as Registered Securities without Coupons, or as Unregistered Securities
with or without Coupons attached thereto of any authorized denomination, and
substantially in the form of the definitive securities of such series but with
such omissions, insertions and variations as may be appropriate for temporary
Registered Securities, all as may be determined by the Issuer with the
concurrence of the Trustee. Temporary Securities may contain such reference to
any provisions of this Indenture as may be appropriate. Every temporary Security
shall be executed by the Issuer and be authenticated by the Trustee upon the
same conditions and in substantially the same manner, and with like effect, as
the definitive Securities. Without unreasonable delay the Issuer shall execute
and shall furnish definitive Securities of such series and thereupon temporary
Registered Securities of such series may be surrendered in exchange therefor
without charge at each office or agency to be maintained by the Issuer for that
purpose pursuant to Section 3.2 and in the case of Unregistered Securities,
together with any unmatured Coupons and any matured Coupons in default
appertaining thereto, at any agency maintained by the Issuer for such purpose as
specified pursuant to Section 2.3 and the Trustee shall authenticate and deliver
in exchange for such temporary Securities of such series a like aggregate
principal amount of definitive Securities of the same series of authorized
denominations and, in the case of Unregistered Securities having attached
thereto any appropriate Coupons. Until so exchanged, the temporary Securities of
any series and any unmatured Coupons appertaining thereto shall be entitled to
the same benefits under this Indenture as definitive Securities of such series
and any unmatured Coupons appertaining thereto. The provisions of this Section
are subject to any restrictions or limitations on the issue and delivery of
temporary Unregistered Securities of any series that may be established pursuant
to Section 2.3 (including any provision that Unregistered Securities of such
series initially be issued in the form of a single global Unregistered Security
to be delivered to a depositary or agency of the Issuer located outside the
United States and the procedures pursuant to which definitive Unregistered
Securities of such series would be issued in exchange for such temporary global
Unregistered Security).

            SECTION 2.12 Computation of Interest. Except as otherwise specified
as contemplated by Section 2.3 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.

                                   ARTICLE III

                             COVENANTS OF THE ISSUER

            SECTION 3.1 Payment of Principal and Interest. The Issuer covenants
and agrees for the benefit of each series of Securities that it will duly and
punctually pay or cause to be paid the principal of, and interest on, each of
the Securities of such series at the place or places, at the respective times
and in the manner provided in this Indenture and in such Securities. The
interest on Unregistered Securities with Coupons attached (together with any
additional amounts payable pursuant to the terms of such Unregistered
Securities) shall be payable only upon presentation and surrender of the several
Coupons for such interest installments as are evidenced thereby as they
severally mature. Except as specified as
<PAGE>   16
                                                                              15

contemplated in Section 2.3, the interest on any temporary Unregistered
Securities (together with any additional amounts payable pursuant to the terms
of such temporary Unregistered Securities) shall be paid, as to the installments
of interest evidenced by Coupons attached thereto, if any, only upon
presentation and surrender thereof, and, as to the other installments of
interest, if any, only upon presentation of such Securities for notation thereon
of the payment of such interest. Each installment of interest on the Registered
Securities of any series may be paid by mailing checks for such interest payable
to or upon the written order of the holders of such Securities entitled thereto
as they shall appear on the registry books of the Issuer. If so provided in the
resolutions or supplemental indenture referred to in Section 2.3, payment of
principal of or interest on the Securities may be made by wire transfer of funds
in the manner set forth in such resolutions or supplemental indenture.

            SECTION 3.2 Offices for Payments, etc. So long as any of the
Securities remain outstanding, the Issuer will maintain in the Borough of
Manhattan, The City of New York, the following for each series of Securities: an
office or agency (a) where the Registered Securities may be presented for
payment, (b) where the Registered Securities may be presented for registration
of transfer and for exchange as in this Indenture provided and (c) where notices
and demands to or upon the Issuer in respect of the Registered Securities or of
this Indenture may be served.

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

            The Issuer will give to the Trustee written notice of the location
of any such office or agency and of any change of location thereof. With respect
to each series of Securities and Coupons whose terms are established pursuant to
Section 2.3, the Issuer hereby designates its office or agency specified in
accordance with Section 2.3 as the initial office to be maintained by it for
each such purpose. In case the Issuer shall fail to maintain any such office or
agency or shall fail to give such notice of the location or of any change in the
location thereof, presentations and demands may be made and notices may be
served at the Corporate Trust Office.

            SECTION 3.3 Appointment to Fill a Vacancy in Office of Trustee. The
Issuer, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner
<PAGE>   17
                                                                              16

provided in Section 6.10, a Trustee, so that there shall at all times be a
Trustee with respect to each series of Securities hereunder.

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

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

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

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

            If the Issuer shall act as its owning paying agent with respect to
the Securities of any series, it will, on or before each due date of the
principal of or interest on the Securities of such series, set aside, segregate
and hold in trust for the benefit of the holders of the Securities of such
series or the Coupons appertaining thereto a sum sufficient to pay such
principal or interest so becoming due. The Issuer will promptly notify the
Trustee of any failure to take such action.

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

            Anything in this Section to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section is subject to the
provisions of Article Ten and Sections 11.3 and 11.4.

            SECTION 3.5 Written Statement to Trustee. The Issuer will deliver to
the Trustee on or before August 1 in each year (beginning with the August 1 next
succeeding execution of the Indenture) a written statement (which need not
comply with Section 12.5) signed by any two of the following officers, the
chairman of the Board of Directors, the president, the chairman of the executive
committee, any vice chairman of the Board of Directors, any vice president, any
treasurer, any assistant treasurer, the secretary or any assistant secretary of
the Issuer, stating that in the course of the performance of their duties as
officers of the Issuer they would normally have knowledge of any default by the
Issuer in the performance of any covenants contained in this Indenture, stating
whether or not they have knowledge of any such
<PAGE>   18
                                                                              17

default and, if so, specifying each such default of which the signers have
knowledge and the nature thereof.

            SECTION 3.6 Luxembourg Publications. In the event of the publication
of any notice pursuant to Section 5.11, 6.10(a), 6.11, 8.2, 11.4 or 13.2, the
party making such publication in the Borough of Manhattan, The City of New York
and London shall also, to the extent that notice is required to be given to
Holders of Securities of any series by applicable Luxembourg law or stock
exchange regulation, as evidenced by an Officers' Certificate delivered to such
party, make a similar publication in Luxembourg.

                                   ARTICLE IV

                           SECURITYHOLDERS' LISTS AND
                      REPORTS BY THE ISSUER AND THE TRUSTEE

            SECTION 4.1 Issuer to Furnish Trustee Information as to Names and
Addresses of Securityholders. The Issuer covenants and agrees that it will
furnish or cause to be furnished to the Trustee a list in such form as the
Trustee may reasonably require of the names and addresses of the holders of the
Securities of each series:

                  (a)   not more than 15 days after each record date for the
            payment of interest on such Securities, as hereinabove specified, as
            of such record date and on dates to be determined pursuant to
            Section 2.3 for non-interest bearing Securities in each year, and

                  (b)   at such other times as the Trustee may request in
            writing, within 30 days after receipt by the Issuer of any such
            request as of a date not more than 15 days prior to the time such
            information is furnished,

provided that if and so long as the Trustee shall be the Security registrar for
such series and all of the Securities of any series are Registered Securities,
such list shall not be required to be furnished.

            SECTION 4.2 Preservation and Disclosure of Securityholders' Lists.
(a) The Trustee shall preserve, in as current a form as is reasonably
practicable, all information as to the names and addresses of the holders of
each series of Securities (i) contained in the most recent list furnished to it
as provided in Section 4.1, (ii) received by it in the capacity of Security
registrar for such series, if so acting and (iii) filed with it within the two
preceding years pursuant to 4.4(c)(ii). The Trustee may destroy any list
furnished to it as provided in Section 4.1 upon receipt of a new list so
furnished.

            (b)   In case three or more holders of Securities (hereinafter
referred to a "applicants") apply in writing to the Trustee and furnish to the
Trustee reasonable proof that each such applicant has owned a Security for a
period of at least six months preceding the date of such application, and such
application states that the applicants desire to communicate with other holders
of Securities of a particular series (in which case the applicants must all hold
Securities of such series) or with Holders of all Securities with respect to
their rights under this Indenture or under such Securities and such application
is accompanied by a copy of the form of proxy or
<PAGE>   19
                                                                              18

other communication which such applicants propose to transmit, then the Trustee
shall, within five Business Days after the receipt of such application, as its
election, either

            (i)   afford to such applicants access to the information preserved
      at the time by the Trustee in accordance with the provisions of subsection
      (a) of this Section, or

            (ii)  inform such applicants as to the approximate number of holders
      of Securities of such series or all Securities, as the case may be, whose
      names and addresses appear in the information preserved at the time by the
      Trustee, in accordance with the provisions of subsection (a) of this
      Section, and as to the approximate cost of mailing to such Securityholders
      the form of proxy or other communication, if any, specified in such
      application.

            If the Trustee shall elect not to afford such applicants access to
such information, the Trustee shall, upon the written request of such
applicants, mail to each Securityholder of such series or all Securities, as the
case may be, whose name and address appears in the information preserved at the
time by the Trustee in accordance with the provisions of subsection (a) of this
Section a copy of the form of proxy or other communication which is specified in
such request, with reasonable promptness after a tender to the Trustee of the
material to be mailed and of payment, or provision for the payment, of the
reasonable expenses of mailing, unless within five days after such tender, the
Trustee shall mail to such applicants and file with the Commission together with
a copy of the material to be mailed, a written statement to the effect that, in
the opinion of the Trustee, such mailing would be contrary to the best interests
of the holders of Securities of such series or all Securities, as the case may
be, or would be in violation of applicable law. Such written statement shall
specify the basis of such opinion. If the Commission, after opportunity for a
hearing upon the objections specified in the written statement so filed, shall
enter an order refusing to sustain any of such objections or if, after the entry
of an order sustaining one or more of such objections, the Commission shall
find, after notice and opportunity for hearing, that all the objections so
sustained have been met, and shall enter an order so declaring, the Trustee
shall mail copies of such material to all such Securityholders with reasonable
promptness after the entity of such order and the renewal of such tender;
otherwise the Trustee shall be relieved of any obligation or duty to such
applicants respecting their application.

            (c)   Each and every holder of Securities and Coupons, by receiving
and holding the same, agrees with the Issuer and the Trustee that neither the
Issuer nor the Trustee nor any agent of the Issuer or the Trustee shall be held
accountable by reason of the disclosure of any such information as to the names
and addresses of the holders of Securities in accordance with the provisions of
subsection (b) of this Section, regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under such subsection
(b).

            SECTION 4.3 Reports by the Issuer. The Issuer covenants:

            (a)   to file with the Trustee, within 15 days after the Issuer is
      required to file the same with the Commission, copies of the annual
      reports and of the information, documents, and other reports (or copies of
      such portions of any of the foregoing as the Commission may from time to
      time by rules and regulations prescribe) which the Issuer
<PAGE>   20
                                                                              19

      may be required to file with the Commission pursuant to Section 13 or
      Section 15(d) of the Securities Exchange Act of 1934, or if the Issuer is
      not required to file information, documents, or reports pursuant to either
      of such Sections, then to file with the Trustee and the Commission, in
      accordance with rules and regulations prescribed from time to time by the
      Commission, such of the supplementary and periodic information, documents,
      and reports which may be required pursuant to Section 13 of the Securities
      Exchange Act of 1934, in respect of a security listed and registered on a
      national securities exchange as may be prescribed from time to time in
      such rules and regulations;

            (b)   to file with the Trustee and the Commission, in accordance
      with rules and regulations prescribed from time to time by the Commission,
      such additional information, documents, and reports with respect to
      compliance by the Issuer with the conditions and covenants provided for in
      this Indenture as may be required from time to time by such rules and
      regulations; and

            (c)   to transmit by mail to the holders of Securities, within 30
      days after the filing thereof with the Trustee, such summaries of any
      information, documents and reports required to be filed by the Issuer
      pursuant to subsections (a) and (b) of this Section as may be required to
      be transmitted to such Holders by rules and regulations prescribed from
      time to time by the Commission.

            SECTION 4.4 Reports by the Trustee. (a) On or before July 15 in each
year following the date hereof, so long as any Securities are outstanding
hereunder, the Trustee shall transmit by mail as provided below to the
Securityholders of each series, as hereinafter in this Section provided, a brief
report dated as of the preceding May 15 with respect to:

            (i)   its eligibility under Section 6.9 and its qualification under
      Section 6.8, or in lieu thereof, if to the best of its knowledge it has
      continued to be eligible and qualified under such Sections, a written
      statement to such effect;

            (ii)  the character and amount of any advances (and if the Trustee
      elects so to state, the circumstances surrounding the making thereof) made
      by the Trustee (as such) which remain unpaid on the date of such report
      and for the reimbursement of which it claims or may claim a lien or
      charge, prior to that of the Securities of any series, on any property or
      funds held or collected by it as Trustee, except that the Trustee shall
      not be required (but may elect) to report such advances if such advances
      so remaining unpaid aggregate not more than -1/2 of 1% of the principal
      amount of the Securities of any series Outstanding on the date of such
      report;

            (iii) the amount, interest rate, and maturity date of all other
      indebtedness owing by the Issuer (or by any other obligor on the
      Securities) to the Trustee in its individual capacity on the date of such
      report, with a brief description of any property held as collateral
      security therefor, except any indebtedness based upon a creditor
      relationship arising in any manner described in Section 6.13(b)(2), (3),
      (4) or (6);

            (iv)  the property and funds, if any, physically in the possession
      of the Trustee (as such) on the date of such report;

                                                                              20

            (v)   any additional issue of Securities which the Trustee has not
      previously reported; and

            (vi)  any action taken by the Trustee in the performance of its
      duties under this Indenture which it has not previously reported and which
      in its opinion in respect of a default, notice of which has been or is to
      be withheld by it in accordance with the provisions of Section 5.11.

            (b)   The Trustee shall transmit to the Securityholders of each
series, as provided in subsection (c) of this Section, a brief report with
respect to the character and amount of any advances (and if the Trustee elects
so to state, the circumstances surrounding the making thereof) made by the
Trustee as such since the date of the last report transmitted pursuant to the
provisions of subsection (a) of this Section (or if no such report has yet been
so transmitted, since the date of this Indenture) for the reimbursement of which
it claims or may claim a lien or charge prior to that of the Securities of such
series on property or funds held or collected by it as Trustee and which it has
not previously reported pursuant to this subsection (b), except that the Trustee
shall not be required (but may elect) to report such advances if such advances
remaining unpaid at any time aggregate 10% or less of the principal amount of
Securities of such series outstanding at such time, such report to be
transmitted within 90 days after such time.

            (c)   Reports pursuant to this Section shall be transmitted by mail:

      (i)   to all registered holders of Securities, as the names and addresses
of such holders appear upon the registry books of the Issuer;

      (ii)  to such other Holders of Securities as have, within two years
preceding such transmission, filed their names and addresses with the Trustee
for that purpose; and

      (iii) except in the case of reports pursuant to subsection (b), to each
Holder of a Security whose name and address are preserved at the time by the
Trustee as provided in Section 4.2(a).

            (d)   A copy of each such report shall, at the time of such
transmission to Securityholders, be furnished to the Issuer and be filed by the
Trustee with each stock exchange upon which the Securities of any applicable
series are listed and also with the Commission. The Issuer agrees to notify the
Trustee with respect to any series when and as the Securities of such series
become admitted to trading on any stock exchange.

            SECTION 5.1 Event of Default Defined; Acceleration of Maturity;
Waiver of Default. "Event of Default" with respect to Securities of any series
wherever used herein, means each one of the following events (whatever the
reason for such Event of Default and whether it shall be voluntary or
involuntary or be effected by operation of law or pursuant to any judgment,

                                                                              21

decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

            (a)   default in the payment of any installment of interest upon any
      of the Securities of such series as and when the same shall become due and
      payable, and continuance of such default for a period of 30 days; or

            (b)   default in the payment of all or any part of the principal on
      any of the Securities of such series as and when the same shall become due
      and payable either at maturity, upon redemption, by declaration or
      otherwise; or

            (c)   default in the payment of any sinking fund installment as and
      when the same shall become due and payable by the terms of a Security of
      such series; or

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

            (e)   a court having jurisdiction in the premises shall enter a
      decree or order for relief in respect of the Issuer in an involuntary case
      under any applicable bankruptcy, insolvency or other similar law now or
      hereafter in effect, or appointing a receiver, liquidator, assignee,
      custodian, trustee, sequestrator (or similar official) of the Issuer or
      for any substantial part of its property or ordering the winding up or
      liquidation of its affairs, and such decree or order shall remain unstayed
      and in effect for a period of 90 consecutive days; or

            (f)   the Issuer shall commence a voluntary case under any
      applicable bankruptcy, insolvency or other similar law now or hereafter in
      effect, or consent to the entry of an order for relief in an involuntary
      case under any such law, or consent to the appointment or taking
      possession by a receiver, liquidator, assignee, custodian, trustee,
      sequestrator (or similar official) of the Issuer or for any substantial
      part of its property, or make any general assignment for the benefit of
      creditors.

If an Event of Default described in clause (a), (b), (c) or (d) above (if the
Event of Default under clause (d) is with respect to less than all series of
Securities then Outstanding) occurs and is continuing, then, and in each and
every such case, unless the principal of all of the Securities of such series
shall have already become due and payable, either the Trustee or the holders of
not less than 25% in aggregate principal amount of the Securities of all series
affected thereby then Outstanding hereunder (each such series voting as a
separate class in the case of an Event of Default under clause (a), (b) or (c)
and all such series voting as one class in the case of an Event of Default under
clause (d)), by notice in writing to the Issuer (and to the Trustee if given by
Securityholders), may declare the entire principal (or, if the Securities of
such series are Original
<PAGE>   23
                                                                              22

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

            The foregoing provisions, however, are subject to the condition that
if, at any time after the principal (or, if the Securities are Original Issue
Discount Securities, such portion of the principal as may be specified in the
terms thereof) of the Securities of any series (or of all the Securities
affected, or of all the Securities, as the case may be) shall have been so
declared due and payable, and before any judgment or decree for the payment of
the moneys due shall have been obtained or entered as hereinafter provided, the
Issuer shall pay or shall deposit with the Trustee a sum sufficient to pay all
matured instalments of interest upon all the Securities of such series (or of
all the Securities affected, or of all the Securities, as the case may be) and
the principal of any and all Securities of such series (or of all the Securities
affected, or of all the Securities, as the case may be) which shall have become
due otherwise than by acceleration (with interest upon such principal and, to
the extent that payment of such interest is enforceable under applicable law, on
overdue instalments of interest, at the same rate as the rate of interest or
Yield to Maturity (in the case of Original Issue Discount Securities) specified
in the Securities of such series (or at the respective rates of interest or
Yields to Maturity of all the Securities affected or all the Securities, as the
case may be) to the date of such payment or deposit) and such amount as shall be
sufficient to cover reasonable compensation to the Trustee, its agents,
attorneys and counsel, and all other expenses and liabilities incurred, and all
advances made, by the Trustee except as a result of negligence or bad faith, and
if any and all Events of Default under the Indenture, other than the non-payment
of the principal of Securities which shall have become due by acceleration,
shall have been cured, waived or otherwise remedied as provided herein -- then
and in every such case the holders of a majority in aggregate principal amount
of the Securities of such series (or of all the Securities affected, or of all
the Securities, as the case may be) then outstanding, by written notice to the
Issuer and to the Trustee, may waive all defaults with respect to such series
(or of all the Securities affected, or with respect to all Securities, as the
case may be -- in such case, treated as a single class) and rescind and annul
such declaration and its consequences, but no such waiver or rescission and
annulment shall extend to or shall affect any subsequent default or shall impair
any right consequent thereon.

            For all purposes under this Indenture, if a portion of the principal
of any Original Issue Discount Securities shall have been accelerated and
declared due and payable pursuant to the provisions hereof, then, from and after
such declaration, unless such declaration has been rescinded and annulled, the
principal amount of such Original Issue Discount Securities shall be deemed, for
all purposes hereunder, to be such portion of the principal thereof as shall be
due
<PAGE>   24
                                                                              23

and payable as a result of such acceleration, and payment of such portion of the
principal thereof as shall be due and payable as a result of such acceleration,
together with interest, if any, thereon and all other amounts owing thereunder,
shall constitute payment in full of such Original issue Discount Securities.

            SECTION 5.2 Collection of Indebtedness by Trustee; Trustee May Prove
Debt. The Issuer covenants that (a) in case default shall be made in the payment
of any installment of interest on any of the Securities of any series or Coupons
appertaining thereto when such interest shall have become due and payable, and
such default shall have continued for a period of 30 days or (b) in case default
shall be made in the payment of all or any part of the principal of any of the
Securities of any series when the same shall have become due and payable,
whether upon maturity of the Securities of such series or upon any redemption or
by declaration or otherwise -- then upon any demand of the Trustee, the Issuer
will pay to the Trustee for the benefit of the Holders of the Securities of such
series the whole amount that then shall have become due and payable on all
Securities of such series and such Coupons, if any, for principal or interest,
as the case may be (with interest to the date of such payment upon the overdue
principal and, to the extent that payment of such interest is enforceable under
applicable law, on overdue instalments of interest at the same rate as the rate
of interest or Yield to Maturity (in the case of Original Issue Discount
Securities) specified in the Securities of such series); and in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including reasonable compensation to the Trustee and
each predecessor Trustee, their respective agents, attorneys and counsel, and
any expenses and liabilities incurred, and all advances made, by the Trustee and
each predecessor Trustee except as a result of its negligence or bad faith.

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

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

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

                                                                              24

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

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

            (c)   to collect and receive any moneys or other property payable or
      deliverable on any such claims, and to distribute all amounts received
      with respect to the claims of the Securityholders and of the Trustee on
      their behalf; and any trustee, receiver, or liquidator, custodian or other
      similar official is hereby authorized by each of the Securityholders to
      make payments to the Trustee, and, in the event that the Trustee shall
      consent to the making of payments directly to the Securityholders, to pay
      to the Trustee such amount as shall be sufficient to cover reasonable
      compensation to the Trustee, each predecessor Trustee and their respective
      agents, attorneys and counsel, and all other expenses and liabilities
      incurred, and all advances made, by the Trustee and each predecessor
      Trustee except as a result of negligence or bad faith, and all other
      amounts due the Trustee and each predecessor Trustee pursuant to Section
      6.6.

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

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

                                                                              25

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

            SECTION 5.3 Application of Proceeds. Any moneys collected by the
Trustee pursuant to this Article in respect of any series shall, subject to
Article Ten, be applied in the following order at the date or dates fixed by the
Trustee and, in case of the distribution of such moneys on account of principal
or interest, upon presentation of the several Securities or Coupons appertaining
to such Securities in respect of which moneys have been collected and stamping
(or otherwise noting) thereon the payment, or issuing Securities of such series
in reduced principal amounts in exchange for the presented Securities of such
series if only partially paid, or upon surrender thereof if fully paid:

            FIRST: To the payment of costs and expenses applicable to such
      series in respect of which moneys have been collected, including
      reasonable compensation to the Trustee and each predecessor Trustee and
      their respective agents and attorneys and of all expenses and liabilities
      incurred, and all advances made, by the Trustee and each predecessor
      Trustee except as a result of negligence or bad faith, and all other
      amounts due to the Trustee or any predecessor Trustee pursuant to Section
      6.6;

            SECOND: In case the principal of the Securities in respect of which
      moneys have been collected shall not have become and be then due and
      payable, to the payment of interest on the Securities of such series in
      default in the order of the maturity of the instalments of such interest,
      with interest (to the extent that such interest has been collected by the
      Trustee) upon the overdue instalments of interests at the same rate as the
      rate of interest or Yield to Maturity (in the case of Original Issue
      Discount Securities) specified in such Securities, such payments to be
      made ratably to the persons entitled thereto, without discrimination or
      preference;

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

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

                                                                              26

            SECTION 5.4 Suits for Enforcement. In case an Event of Default has
occurred, has not been waived and is continuing, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

            SECTION 5.5 Restoration of Rights on Abandonment of Proceedings. In
case the Trustee shall have proceeded to enforce any right under this Indenture
and such proceedings shall have been discontinued or abandoned for any reason,
or shall have been determined adversely to the Trustee, then and in every such
case the Issuer and the Trustee shall be restored respectively to their former
positions and rights hereunder, and all rights, remedies and powers of the
Issuer, the Trustee and the Securityholders shall continue as though no such
proceedings had been taken.

            SECTION 5.6 Limitations on Suits by Securityholders. No holder of
any Security of any series or of any Coupon appertaining thereto shall have any
right by virtue or by availing of any provision of this Indenture to institute
any action or proceeding at law or in equity or in bankruptcy or otherwise upon
or under or with respect to this Indenture, or for the appointment of a trustee,
receiver, liquidator, custodian or other similar official or for any other
remedy hereunder, unless such holder previously shall have given to the Trustee
written notice of default and of the continuance thereof, as hereinbefore
provided, and unless also the Holders of not less than 25% in aggregate
principal amount of the Securities of such series then Outstanding shall have
made written request upon the Trustee to institute such action or proceedings in
its own name as trustee hereunder and shall have offered to the Trustee such
reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby and the Trustee for 60 days after
its receipt of such notice, request and offer of indemnity shall have failed to
institute any such action or proceeding and no direction inconsistent with such
written request shall have been given to the Trustee pursuant to Section 5.9; it
being understood and intended, and being expressly covenanted by the taker and
Holder of every Security or Coupon with every other taker and Holder and the
Trustee, that no one or more Holders of Securities of any series or Coupons
appertaining to such Securities shall have any right in any manner whatever by
virtue or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of any other Holder of Securities or Coupons of that or any
other series or Coupons appertaining to such Securities, or to obtain or seek to
obtain priority over or preference to any other such Holder or to enforce any
right under this Indenture, except in the manner herein provided and for the
equal, ratable and common benefit of all Holders of Securities or Coupons of the
applicable series or Coupons appertaining to such Securities. For the protection
and enforcement of the provisions of this Section, each and every Securityholder
and the Trustee shall be entitled to such relief as can be given either at law
or in equity.

            SECTION 5.7 Unconditional Right of Securityholders to Institute
Certain Suits. Notwithstanding any other provision in this Indenture and any
provision of any Security or Coupon, but subject to Article Ten, the right of
any Holder of any Security or Coupon, but subject to Article Ten, the right of
any Holder of any Security or Coupon to receive payment of
<PAGE>   28
                                                                              27

the principal of and interest on such Security or Coupon on or after the
respective due dates expressed in such Security or Coupon, or to institute suit
for the enforcement of any such payment on or after such respective dates, shall
not be impaired or affected without the consent of such Holder.

            SECTION 5.8 Powers and Remedies Cumulative; Delay or Omission Not
Waiver of Default. Except as provided in Section 5.6, no right or remedy herein
conferred upon or reserved to the Trustee or to the holder of Securities or
Coupons is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

            No delay or omission of the Trustee or of any holder of Securities
or Coupons to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power or
shall be construed to be a waiver of any such Event of Default or an
acquiescence therein; and, subject to Section 5.6, every power and remedy given
by this Indenture or by law to the Trustee or to the holder of Securities or
Coupons may be exercised from time to time, and as often as shall be deemed
expedient, by the Trustee or by the holder of Securities or Coupons.

            SECTION 5.9 Control by Securityholders. The Holders of a majority in
aggregate principal amount of the Securities of each series affected (with each
series voting as a separate class) at the time Outstanding shall have the right
to direct the time, method, and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee with respect to the Securities of such series by this Indenture;
provided that such direction shall not be otherwise than in accordance with law
and the provisions of this Indenture and provided further that (subject to the
provisions of Section 6.1) the Trustee shall have the right to decline to follow
any such direction if the Trustee, being advised by counsel, shall determine
that the action or proceeding so directed may not lawfully be taken or if the
Trustee in good faith by its board of directors, the executive committee, or a
trust committee of directors or Responsible Officer or Officers of the Trustee
shall determined that the action or proceedings so directed would involve the
Trustee in personal liability or if the Trustee in good faith shall so determine
that the actions or forebearances specified in or pursuant to such direction
would be unduly prejudicial to the interests of Holders of Securities of all
series so affected not joining in the giving of said direction, it being
understood that (subject to Section 6.1) the Trustee shall have no duty to
ascertain whether or not such actions or forebearances are unduly prejudicial to
such Holders.

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

            SECTION 5.10 Waiver of Past Defaults. Prior to the declaration of
the acceleration of the maturity of the Securities of any series as provided in
Section 5.1, the Holders of a majority in aggregate principal amount of the
Securities of such series at the time Outstanding may on behalf of the Holders
of all the Securities of such series waive any past
<PAGE>   29
                                                                              28

default or Event of Default described in clause (d) of Section 5.1 (if such
default or Event of Default under clause (d) is with respect to less than all
the Securities then Outstanding) or, in the case of an event specified in clause
(d), (e) or (f) of Section 5.1 (if such default or Event of Default under clause
(d) is with respect to all the Securities then Outstanding), the Holders of
Securities of a majority in principal amount of all the Securities then
outstanding (voting as one class) may waive any such default or Event of
Default, and its consequences except a default in respect of a covenant or
provision hereof which cannot be modified or amended without the consent of the
Holder of each Security affected. In the case of any such waiver, the Issuer,
the Trustee and the holder of Securities of such series shall be restored to
their former positions and rights hereunder, respectively; but no such waiver
shall extend to any subsequent or other default or impair any right consequent
thereon.

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

            SECTION 5.11 Trustee to Give Notice of Default, But May Withhold in
Certain Circumstances. The Trustee shall, within 90 days after the occurrence of
a default with respect to the Securities of any series known to the Trustee,
provide notice to the Holders of Securities of such series and Coupons
appertaining thereto, if any, (i) if any Unregistered Securities of that series
are then Outstanding, to the Holders thereof, by publication at least once in an
Authorized Newspaper in the Borough of Manhattan, The City of New York and at
least once in an Authorized Newspaper in London (and, if required by Section
3.6, at least once in an Authorized Newspaper in Luxembourg), (ii) if any
Unregistered Securities of that series are then Outstanding, to all Holders
thereof who have filed their names and addresses with the Trustee pursuant to
Section 4.4 (c) (ii), by mailing such notice to such Holders at such addresses
and (iii) to all Holders of then Outstanding Registered Securities of that
series, by mailing such notice to such Holders at their addresses as they shall
appear in the registry books, unless such default have been cured before the
giving of such notice (the term "default" or "defaults" for the purposes of this
Section being hereby defined to mean any event or condition which is, or with
notice or lapse of time or both would become, an Event of Default); provided
that, except in the case of default in the payment of the principal of or
interest on any of the Securities of such series, the Trustee shall be protected
in withholding such notice if and so long as the board of directors, the
executive committee, or a trust committee of directors or Responsible Officer or
Officers of the Trustee in good faith determines that the withholding of such
notice is in the interests of the Securityholders of such series.

            SECTION 5.12 Right of Court to Require Filing of Undertaking to Pay
Costs. All parties to this Indenture agree, and each Holder of any Security or
Coupon by his acceptance thereof shall be deemed to have agreed, that any court
may in its discretion require, in any suit for the enforcement of any right or
remedy under this Indenture or in any suit against the Trustee for any action
taken, suffered or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party
<PAGE>   30
                                                                              29

litigant; but the provisions of this Section shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Securityholder or group
of Securityholders of any series holding in the aggregate more than 10% in
aggregate principal amount of the Securities of such series (or, in the case of
any suit relating to or arising under clause (d) (if the suit under clause (d)
related to all the Securities then Outstanding), (e) or (f) of Section 5.1, 10%
in aggregate principal amount of all Securities) Outstanding, or to any suit
instituted by any Securityholder for the enforcement of the payment of the
principal of or interest on any Security or Coupon on or after the due date
expressed in such Security or Coupon.

                                   ARTICLE VI

                             CONCERNING THE TRUSTEE

            SECTION 6.1 Duties and Responsibilities of the Trustee; During
Default; Prior to Default. With respect to the Holders of any series of
Securities issued hereunder, the Trustee, prior to the occurrence of an Event of
Default with respect to the Securities of a particular series and after the
curing or waiving of all Events of Default which may have occurred with respect
to such series, undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture. In case an Event of Default with
respect to the Securities of a series has occurred (which has not been cured or
waived) the Trustee shall exercise such of the rights and powers vested in it by
this Indenture, and use the same degree of care and skill in their exercise, as
a prudent man would exercise or use under the circumstances in the conduct of
his own affairs.

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

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

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

                  (ii)  in the absence of bad faith on the part of the Trustee,
            the Trustee may conclusively rely, as to the truth of the statements
            and the correctness of the opinions expressed therein, upon any
            statements, certificates or opinions furnished to the Trustee and
            conforming to the requirements of this Indenture; but in the case of
            any such statements, certificates or opinions which by any provision
            hereof are specifically required to be furnished to the Trustee, the
            Trustee shall be under a duty to examine the same to determine
            whether or not they conform to the requirements of this Indenture;
<PAGE>   31
                                                                              30

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

            (c)   the Trustee shall not be liable with respect to any action
      taken or omitted to be taken by it in good faith in accordance with the
      direction of the Holders pursuant to Section 5.9 relating to the time,
      method and place of conducting any proceeding for any remedy available to
      the Trustee, or exercising any trust or power conferred upon the Trustee,
      under this Indenture.

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

            SECTION 6.2 Certain Rights of the Trustee. Subject to Section 6.1:

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

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

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

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

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

            (f)   prior to the occurrence of an Event of Default hereunder and
      after the curing or waiving of all Events of Default, the Trustee shall
      not be bound to make any investigation into the facts or matters stated in
      any resolution, certificate, statement,
<PAGE>   32
                                                                              31

      instrument, opinion, report, notice, request, consent, order, approval,
      appraisal, bond, debenture, note, Coupon, security, or other paper or
      document unless requested in writing so to do by the holders of not less
      than a majority in aggregate principal amount of the Securities of all
      series affected then Outstanding; provided that, if the payment within a
      reasonable time to the Trustee of the costs, expenses or liabilities
      likely to be incurred by it in the making of such investigation is, in the
      opinion of the Trustee, not reasonably assured to the Trustee by the
      security afforded to it by the terms of this Indenture, the Trustee may
      require reasonable indemnity against such expenses or liabilities as a
      condition to proceeding; the reasonable expenses of every such
      investigation shall be paid by the Issuer or, if paid by the Trustee or
      any predecessor trustee, shall be repaid by the Issuer upon demand;

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

            (h)   the Trustee shall not be liable for any action taken or
      omitted to be taken by any transfer agent or paying agent unless such
      action taken or omitted was so taken or omitted at the direction of the
      Trustee.

            SECTION 6.3 Trustee Not Responsible for Recitals, Disposition of
Securities or Application of Proceeds Thereof. The recitals contained herein and
in the Securities or Coupons, except the Trustee's certificates of
authentication, shall be taken as the statements of the Issuer, and the Trustee
assumes no responsibility for the correctness of the same. The Trustee makes no
representation as to the validity or sufficiency of this Indenture or of the
Securities or Coupons. The Trustee shall not be accountable for the use or
application by the Issuer of any of the Securities or of the proceeds thereof.

            SECTION 6.4 Trustee and Agents May Hold Securities or Coupons;
Collections, etc. The Trustee or any agent of' the Issuer or the Trustee, in its
individual or any other capacity, may become the owner or pledgee of Securities
or Coupons with the same rights it would have if it were not the Trustee or such
agent and, subject to Sections 6.8 and 6.13, if operative, may otherwise deal
with the Issuer and receive, collect, hold and retain collections from the
Issuer with the same rights it would have if it were not the Trustee or such
agent.

            SECTION 6.5 Moneys Held by Trustee. Subject to the provisions of
Section 11.4 hereof, all moneys received by the Trustee shall, until used or
applied as herein provided, be held in trust for the purposes for which they
were received, but need not be segregated from other funds except to the extent
required by mandatory provisions of law. Neither the Trustee nor any agent of
the Issuer or the Trustee shall be under any liability for interest on any
moneys received by it hereunder except such as it may agree with the Issuer to
pay thereon.

            SECTION 6.6 Compensation and Indemnification of Trustee and Its
Prior Claim. The Issuer covenants and agrees to pay to the Trustee from time to
time, and the Trustee shall be entitled to, reasonable compensation (which shall
not be limited by any provision of law in regard to the compensation of a
trustee of an express trust) and the Issuer covenants and agrees to pay or
reimburse the Trustee and each predecessor Trustee upon its request for all
<PAGE>   33
                                                                              32

reasonable expenses, disbursements and advances incurred or made by or on behalf
of it in accordance with any of the provisions of this indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all agents and other persons not regularly in its employ) except any such
expense, disbursement or advance as may arise from its negligence or bad faith.
The Issuer also covenants to indemnify the Trustee and each predecessor Trustee
for, and to hold it harmless against, any loss, liability or expense incurred
without negligence or bad faith on its part, arising out of or in connection
with the acceptance or administration of this Indenture or the trusts hereunder
and its duties hereunder, including the costs and expenses of defending itself
against or investigating any claim of liability in the premises. The obligations
of the Issuer under this Section to compensate and indemnify the Trustee and
each predecessor Trustee and to pay or reimburse the Trustee and each
predecessor Trustee for expenses, disbursements and advances shall constitute
additional indebtedness hereunder and shall survive the satisfaction and
discharge of this Indenture. Such additional indebtedness shall have a claim
prior to that of the Securities or Coupons upon all property and funds held or
collected by the Trustee as such, except funds held in trust for the benefit of
the holders of particular Securities or Coupons. Payments to the Trustee
pursuant to this Section 6.6 shall not be subject to the provisions of Article
Ten.

            SECTION 6.7 Right of Trustee to Rely on Officers' Certificate, etc.
Subject to Sections 6.1 and 6.2, whenever in the administration of the trusts of
this Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or bad faith on the
part of the Trustee, be deemed to be conclusively proved and established by an
Officers' Certificate delivered to the Trustee, and such Certificate, in the
absence of negligence or bad faith on the part of the Trustee, shall be full
warrant to the Trustee for any action taken, suffered or omitted by it under the
provisions of this indenture upon the faith thereof.

            SECTION 6.8 Qualification of Trustee; Conflicting Interests. (a) If
the Trustee has or shall acquire any conflicting interest, as defined in this
Section, it shall, within 90 days after ascertaining that it has such
conflicting interest, either eliminate such conflicting interest or resign in
the manner and with the effect specified in this Indenture.

            (b)   In the event that the Trustee shall fail to comply with the
provisions of subsection (a) of this Section, the Trustee shall, within 10 days
after the expiration of such 90 day period, provide notice of such failure to
the Securityholders in the manner and to the extent required by Section 4.4(c).

            (c)   For the purposes of this Section, the Trustee shall be deemed
to have a conflicting interest with respect to Securities of any series if

            (i)   the Trustee is trustee under this Indenture with respect to
      the outstanding Securities of any other series or is a trustee under
      another indenture under which any other securities, or certificates of
      interest or participation in any other securities, of the Issuer are
      outstanding, unless such other indenture is a collateral trust indenture
      under which the only collateral consists of Securities issued under this
      Indenture, provided that there shall be excluded from the operation of
      this paragraph the indenture dated as of February 28, 1985 between the
      Issuer and the Trustee under which the Issuer's 11 1/4%
<PAGE>   34
                                                                              33

      Subordinated Notes Due 1992 are outstanding and the Indenture dated as of
      November 19, 1985 between the Issuer and the Trustee under which the
      Issuer's 10 3/8% Subordinated Notes Due 1992 are outstanding; and there
      shall also be so excluded any other indenture or indentures under which
      other securities, or certificates of interest or participation in other
      securities, of the Issuer are outstanding if (i) this Indenture, with
      respect to Securities of such series and, if applicable, this Indenture
      with respect to such other series issued pursuant to this Indenture and
      such other indenture or indentures are wholly unsecured, and such other
      indenture or indentures are hereafter qualified under the Trust Indenture
      Act of 1939, unless the Commission shall have found and declared by order
      pursuant to Section 305(b) or Section 307(c) of such Trust Indenture Act
      of 1939 that differences exist between the provisions of this Indenture
      with respect to Securities of such series and one or more other series, or
      the provisions of this indenture and the provisions of such other
      indenture or indentures which are so likely to involve a material conflict
      of interest as to make it necessary in the public interest or for the
      protection of investors to disqualify the Trustee from acting as such
      under this Indenture with respect to Securities of such series and such
      other series, or under this Indenture or such other indenture or
      indentures, or (ii) the Issuer shall have sustained the burden of proving,
      on application to the Commission and after opportunity for hearing
      thereon, that trusteeship under this Indenture with respect to Securities
      of such series and such other series, or under this Indenture and such
      other indenture or indentures is not so likely to involve a material
      conflict of interest as to make it necessary in the public interest or for
      the protection of investors to disqualify the Trustee from acting as such
      under this indenture with respect to Securities of such series and such
      other series, or under this indenture and such other indentures;

            (ii)  the Trustee or any of its directors or executive officers is
      an obligor upon the Securities of any series issued under this Indenture
      or an underwriter for the Issuer;

            (iii) the Trustee directly or indirectly controls or is directly or
      indirectly controlled by or is under direct or indirect common control
      with the Issuer or an underwriter for the Issuer;

            (iv)  the Trustee or any of its directors or executive officers is a
      director, officer, partner, employee, appointee, or representative of the
      Issuer, or of an underwriter (other than the Trustee itself) for the
      Issuer who is currently engaged in the business of underwriting, except
      that (x) one individual may be a director or an executive officer, or
      both, of the Trustee and a director or an executive officer or both of the
      Issuer, but may not be at the same time an executive officer of both the
      Trustee and the Issuer; (y) if and so long as the number of directors of
      the Trustee in office is more than nine, one additional individual may be
      a director or an executive officer, or both, of the Trustee and a director
      of the Issuer; and (z) the Trustee may be designated by the Issuer or by
      any underwriter for the Issuer to act in the capacity of transfer agent,
      registrar, custodian, paying agent, fiscal agent, escrow agent, or
      depositary, or in any other similar capacity, or, subject to the
      provisions of subsection (c)(i) of this Section to act as trustee, whether
      under an indenture or otherwise;

            (v)   10% or more of the voting securities of the Trustee is
      beneficially owned either by the issuer or by any director, partner or
      executive officer thereof, or 20% or
<PAGE>   35
                                                                              34

      more of such voting securities is beneficially owned, collectively, by any
      two or more of such persons; or 10% or more of the voting securities of
      the Trustee is beneficially owned either by an underwriter for the Issuer
      or by any director, partner, or executive officer thereof, or is
      beneficially owned, collectively, by any two or more such persons;

            (vi)  the Trustee is the beneficial owner of, or holds as collateral
      security for an obligation which is in default, (x) 5% or more of the
      voting securities or 10% or more of any other class of security of the
      Issuer, not including the Securities issued under this Indenture and
      securities issued under any other indenture under which the Trustee is
      also trustee, or (y) 10% or more of any class of security of an
      underwriter for the Issuer;

            (vii) the Trustee is the beneficial owner of, or holds as collateral
      security for an obligation which is in default, 5% or more of the voting
      securities of any person who, to the knowledge of the Trustee, owns 10% or
      more of the voting securities of, or controls directly or indirectly or is
      under direct or indirect common control with, the Issuer;

            (viii) the Trustee is the beneficial owner of, or holds as
      collateral security for an obligation which is in default, 10% or more of
      any class of security of any person who to the knowledge of the Trustee,
      owns 50% or more of the voting securities of the Issuer; or

            (ix)  the Trustee owns on May 15 in any calendar year, in the
      capacity of executor, administrator, testamentary or inter vivos trustee,
      guardian, committee or conservator, or in any other similar capacity, an
      aggregate of 25% or more of the voting securities, or of any class of
      security, of any person, the beneficial ownership of a specified
      percentage of which would have constituted a conflicting interest under
      Section 6.8(c)(vi), (vii) or (viii). As to any such securities of which
      the Trustee acquired ownership through becoming executor, administrator,
      or testamentary trustee of an estate which included them, the provisions
      of the preceding sentence shall not apply, for a period of two years from
      the date of such acquisition, to the extent that such securities included
      in such estate do not exceed 25% of such voting securities or 25% of any
      such class of security. Promptly after May 15 in each calendar year, the
      Trustee shall make a check of its holdings of such securities in any of
      the above-mentioned capacities as of such May 15. If the Issuer fails to
      make payment in full of principal of or interest on any of the Securities
      when and as the same becomes due and payable, and such failure continues
      for 30 days thereafter, the Trustee shall make a prompt check of its
      holdings of such securities in any of the above-mentioned capacities as of
      the date of the expiration of such 30-day period, and after such date,
      notwithstanding the foregoing provisions of this paragraph, all such
      securities so held by the Trustee, with sole or joint control over such
      securities vested in it, shall, but only so long as such failure shall
      continue, be considered as though beneficially owned by the Trustee for
      the purposes of subsections (c)(vi), (vii) and (viii) of this Section.

            The specification of percentages in subsections (c)(v) to (ix)
inclusive of this Section shall not be construed as indicating that the
ownership of such percentages of the securities of a person is or is not
necessary or sufficient to constitute direct or indirect control for the
purposes of subsections (c)(iii) or (vii) of this Section.

            For the purposes of subsections (c)(vi), (vii), (viii) and (ix)r
of this Section, only,

      of a person;

            (v)   the term "Issuer" shall mean any obligor upon the Securities;
      and

            (vi)  the term "executive officer" shall mean the president, every

      of whom is referred to as a "person" in this paragraph) means such amount
      of the outstanding voting securities of such person as entitles the holder

      of such person;

            (ii)  a specified percentage of a class of securities of a person

      outstanding;

            (iii) the term "amount", when used in regard to securities, means
      the principal amount if relating to evidences of indebtedness, the number
      of shares if relating to capital shares, and the number of units if
      relating to any other kind of security;

            (iv)  the term "outstanding" means issued and not held by or for the
      account of the issuer; the following securities shall not be deemed

                  (A)   securities of an issuer held in a sinking fund relating
            to securities of the issuer of the same class;

                  (B)   securities of an issuer held in a sinking fund relating
            to another class of securities of the issuer, if the obligation
            evidenced by such other class of securities is not in default as to
            principal or interest or otherwise;

                  (C)   securities pledged by the issuer thereof as security for
            an obligation of the issuer not in default as to principal or

<PAGE>   38
                                                                              37

            (v)   a security shall be deemed to be of the same class as another
      security if both securities confer upon the holder or holders thereof
      substantially the same rights and privileges; provided that, in the case
      of secured evidences of indebtedness, all of which are issued under a
      single indenture, differences in the interest rates or maturity dates of
      various series thereof shall not be deemed sufficient to constitute such
      series different classes and provided, further, that, in the case of
      unsecured evidences of indebtedness, differences in the interest rates or
      maturity dates thereof shall not be deemed sufficient to constitute them
      securities of different classes, whether or not they are issued under a
      single indenture.

            SECTION 6.9 Persons Eligible for Appointment as Trustee. The Trustee
for each series of Securities hereunder shall at all times be a corporation
organized and doing business under the laws of the United States of America or
of any State or the District of Columbia having a combined capital and surplus
of at least $5,000,000, and which is authorized under such laws to exercise
corporate trust powers and is subject to supervision or examination by Federal,
State or District of Columbia authority. Such corporation shall have its
corporate trust office in the Borough of Manhattan, The City of New York, if
there be such a corporation in such location willing to act upon reasonable and
customary terms and conditions. If such corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such corporation shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. In case at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, the Trustee shall
resign immediately in the manner and with the effect specified in Section 6.10.

            SECTION 6.10 Resignation and Removal; Appointment of Successor
Trustee. (a) The Trustee, or any trustee or trustees hereafter appointed, may at
any time resign with respect to one or more or all series of Securities by
giving written notice of resignation to the Issuer and (i) if any Unregistered
Securities of a series affected are then Outstanding, by giving notice of such
resignation to the Holders thereof, by publication at least once in an
Authorized Newspaper in the Borough of Manhattan, The City of New York, and at
least once in an Authorized Newspaper in London (and, if required by Section
3.6. at least once in an Authorized Newspaper in Luxembourg), (ii) if any
Unregistered Securities of a series affected are then Outstanding, by mailing
notice of such resignation to the Holders thereof who have filed their names and
addresses with the Trustee pursuant to Section 4.4(c)(ii) at such addresses as
were so furnished to the Trustee (iii) if any Registered Securities of a series
affected are then outstanding, by mailing notice thereof by first class mail to
holders of the applicable series of Securities at their last addresses as they
shall appear on the Security register. Upon receiving such notice of
resignation, the Issuer shall promptly appoint a successor trustee or trustees
with respect to the applicable series by written instrument in duplicate,
executed by authority of the Board of Directors, one copy of which instrument
shall be delivered to the resigning Trustee and one copy to the successor
trustee or trustees. If no successor trustee shall have been so appointed with
respect to any series and have accepted appointment within 60 days after the
mailing of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor trustee, or
any Securityholder who has been a bona fide holder of a Security or Securities
of the applicable series for at least six months may, subject to the provisions
of Section 5.12, on behalf of himself and all others similarly situated,
petition any
<PAGE>   39
                                                                              38

such court for the appointment of a successor trustee. Such court may thereupon,
after such notice, if any, as it may deem proper and prescribe, appoint a
successor trustee.

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

            (i)   the Trustee shall fail to comply with the provisions of
      Section 6.8 with respect to any series of Securities after written request
      therefor by the Issuer or by any Securityholder who has been a bona fide
      holder of a Security or Securities of such series for at least six months;
      or

            (ii)  the Trustee shall cease to be eligible in accordance with the
      provisions of Section 6.9 and shall fail to resign after written request
      therefor by the Issuer or by any Securityholder; or

            (iii) the Trustee shall become incapable of acting with respect to
      any series of Securities, or shall be adjudged a bankrupt or insolvent, or
      a receiver or liquidator of the Trustee or of its property shall be
      appointed, or any public officer shall take charge or control of the
      Trustee or of its property or affairs for the purpose of rehabilitation,
      conservation or liquidation;

then, in any such case, the Issuer may remove the Trustee with respect to the
applicable series of Securities and appoint a successor trustee for such series
by written instrument, in duplicate, executed by order of the Board of Directors
of the Issuer, one copy of which instrument shall be delivered to the Trustee so
removed and one copy to the successor trustee, or, subject to the provisions of
Section 5.12, any Securityholder who has been a bona fide holder of a Security
or Securities of such series for at least six months may on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction
for the removal of the Trustee and the appointment of a successor trustee with
respect to such series. Such court may thereupon, after such notice, if any, as
it may deem proper and prescribe, remove the Trustee and appoint a successor
trustee.

            (c)   The holders of a majority in aggregate principal amount of the
Securities of each series at the time Outstanding may at any time remove the
Trustee with respect to Securities of such series and appoint a successor
trustee with respect to the Securities of such series by delivering to the
Trustee so removed, to the successor trustee so appointed and to the Issuer the
evidence provided for in Section 7.1 of the action in that regard taken by the
Securityholders.

            (d)   Any resignation or removal of the Trustee with respect to any
series and any appointment of a successor trustee with respect to such series
pursuant to any of the provisions of this Section 6.10 shall become effective
upon acceptance of appointment by the successor trustee as provided in Section
6.11.

            SECTION 6.11 Acceptance of Appointment by Successor Trustee. Any
successor trustee appointed as provided in Section 6.10 shall execute and
deliver to the Issuer and to its predecessor trustee an instrument accepting
such appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee with respect to all or any applicable series shall become
effective and such successor trustee, without any further act, deed
<PAGE>   40
                                                                              39

or conveyance, shall become vested with all rights, powers, duties and
obligations with respect to such series of its predecessor hereunder, with like
effect as if originally named as trustee for such series hereunder; but,
nevertheless, on the written request of the Issuer or of the successor trustee,
upon payment of its charges then unpaid, the trustee ceasing to act shall,
subject to Section 11.4, pay over to the successor trustee all moneys at the
time held by it hereunder and shall execute and deliver an instrument
transferring to such successor trustee all such rights, powers, duties and
obligations. Upon request of any such successor trustee, the Issuer shall
execute any and all instruments in writing for more fully and certainly vesting
in and confirming to such successor trustee all such rights and powers. Any
trustee ceasing to act shall, nevertheless, retain a prior claim upon all
property or funds held or collected by such trustee to secure any amounts then
due it pursuant to the provisions of Section 6.6.

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

            No successor trustee with respect to any series of Securities shall
accept appointment as provided in this Section 6.11 unless at the time of such
acceptance such successor trustee shall be qualified under the provisions of
Section 6.8 and eligible under the provisions of Section 6.9.

            Upon acceptance of appointment by any successor trustee as provided
in this Section, the Issuer shall give notice thereof (a) if any Unregistered
Securities of a series affected are then Outstanding, to the Holders thereof, by
publication of such notice at least once in an Authorized Newspaper in the
Borough of Manhattan, The City of New York and at least once in an Authorized
Newspaper in London (and, if required by Section 3.6, at least once in an
Authorized Newspaper in Luxembourg), (b) if any Unregistered Securities of a
series affected are then Outstanding, to the Holders thereof who have filed
their names and addresses with the Trustee pursuant to Section 4.4(c)(ii), by
mailing such notice to such Holders at such addresses as were so furnished to
the Trustee (and the Trustee shall make such information available to the Issuer
for such purpose) and (c) if any Registered Securities of a series affected are
then Outstanding, to the Holders of Registered Securities of each series
affected, by first-class mail to such Holders of Securities of any series for
which such successor trustee is acting as trustee at their last addresses as
they shall appear in the Security Register. If the acceptance of appointment is
substantially contemporaneous with the resignation, then the notice called for
by the preceding sentence may be combined with the notice called for by Section
6.10. If the Issuer fails to mail such notice within ten days after acceptance
of appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Issuer.

                                                                              40

            SECTION 6.12 Merger, Conversion, Consolidation or Succession to
Business of Trustee. Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided that such
corporation shall be qualified under the provisions of Section 6.8 and eligible
under the provisions of Section 6.9, without the execution or filing of any
paper or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding.

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

            SECTION 6.13 Preferential Collection of Claims Against the Issuer.
(a) Subject to the provisions of this Section, if the Trustee shall be or shall
become a creditor, directly or indirectly, secured or unsecured, of the Issuer
within four months prior to a default, as defined in subsection (c) of this
Section, or subsequent to such a default, then, unless and until such default
shall be cured, the Trustee shall set apart and hold in a special account for
the benefit of the Trustee individually, the holders of the Securities and the
holders of other indenture securities (as defined in this Section):

            (1)   An amount equal to any and all reductions in the amount due
      and owing upon any claim as such creditor in respect of principal or
      interest, effected after the beginning of such four months' period and
      valid as against the Issuer and its other creditors, except any such
      reduction resulting from the receipt or disposition of any property
      described in subsection (a)(2) of this Section, or from the exercise of
      any right of set-off which the Trustee could have exercised if a petition
      in bankruptcy had been filed by or against the Issuer upon the date of
      such default; and

            (2)   All property received by the Trustee in respect of any claim
      as such creditor, either as security therefor, or in satisfaction or
      composition thereof, or otherwise, after the beginning of such four
      months' period, or an amount equal to the proceeds of any such property,
      if disposed of, subject, however, to the rights, if any, of the Issuer and
      its other creditors in such property or such proceeds.

            Nothing herein contained, however, shall affect the right of the
Trustee:

            (A)   To retain for its own account (i) payments made on account of
      any such claim by any person (other than the Issuer) who is liable
      thereon, (ii) the proceeds of the bona fide sale of any such claim by the
      Trustee to a third person, and (iii) distributions
<PAGE>   42
                                                                              41

      made in cash, securities or other property in respect of claims filed
      against the Issuer in bankruptcy or receivership or in proceedings for
      reorganization pursuant to Title 11 of the United States Code or
      applicable state law;

            (B)   To realize, for its own account, upon any property held by it
      as security for any such claim, if such property was so held prior to the
      beginning of such four months' period;

            (C)   To realize, for its own account, but only to the extent of the
      claim hereinafter mentioned, upon any property held by it as security for
      any such claim, if such claim was created after the beginning of such four
      months' period and such property was received as security therefor
      simultaneously with the creation thereof, and if the Trustee shall sustain
      the burden of proving that at the time such property was so received the
      Trustee had no reasonable cause to believe that a default as defined in
      subsection (c) of this Section would occur within four months; or

            (D)   To receive payment on any claim referred to in paragraph (B)
      or (C), against the release of any property held as security for such
      claim as provided in such paragraph (B) or (C), as the case may be, to the
      extent of the fair value of such property.

            For the purposes of paragraphs (B), (C) and (D), property
substituted after the beginning of such four months' period for property held as
security at the time of such substitution shall, to the extent of the fair value
of the property released, have the same status as the property released, and, to
the extent that any claim referred to in any of such paragraphs is created in
renewal of or in substitution for or for the purpose of repaying or refunding
any pre-existing claim of the Trustee as such creditor, such claim shall have
the same status as such pre-existing claim.

            If the Trustee shall be required to account, the funds and property
held in such special account and the proceeds thereof shall be apportioned
between the Trustee, the Securityholders and the holders of other indenture
securities in such manner that the Trustee, such Securityholders and the holders
of other indenture securities realize, as a result of payments from such special
account and payments of dividends on claims filed against the Issuer in
bankruptcy or receivership or in proceedings for reorganization pursuant to
Title 11 of the United States Code or applicable State law, the same percentage
of their respective claims, figured before crediting to the claim of the Trustee
anything on account of the receipt by it from the Issuer of the funds and
property in such special account and before crediting to the respective claims
of the Trustee, such Securityholders and the holders of other indenture
securities dividends on claims filed against the Issuer in bankruptcy or
receivership or in proceedings for reorganization pursuant to Title 11 of the
United States Code or applicable State law, but after crediting thereon receipts
on account of the indebtedness represented by their respective claims from all
sources other than from such dividends and from the funds and property so held
in such special account. As used in this paragraph, with respect to any claim,
the term "dividends" shall include any distribution with respect to such claim,
in bankruptcy or receivership or in proceedings for reorganization pursuant to
Title 11 of the United States Code or applicable State law, whether such
distribution is made in cash, securities or other property, but shall not
include any such distribution with respect to the secured portion, if any, of
such claim. The court in which such bankruptcy, receivership or proceeding for
reorganization is pending shall have
<PAGE>   43
                                                                              42

jurisdiction (i) to apportion between the Trustee, such Securityholders and the
holders of other indenture securities, in accordance with the provisions of this
paragraph, the funds and property held in such special account and the proceeds
thereof, or (ii) in lieu of such apportionment, in whole or in part, to give to
the provisions of this paragraph due consideration in determining the fairness
of the distributions to be made to the Trustee, such Securityholders and the
holders or other indenture securities with respect to their respective claims,
in which event it shall not be necessary to liquidate or to appraise the value
of any securities or other property held in such special account or as security
for any such claim, or to make a specific allocation of such distributions as
between the secured and unsecured portions of such claims, or otherwise to apply
the provisions of this paragraph as a mathematical formula.

            Any Trustee who has resigned or been removed after the beginning of
such four months' period shall be subject to the provisions of this subsection
(a) as though such resignation or removal had not occurred. If any Trustee has
resigned or been removed prior to the beginning of such four months' period, it
shall be subject to the provisions of this subsection (a) if and only if the
following conditions exist:

            (i)   the receipt of property or reduction of claim which would have
      given rise to the obligation to account, if such Trustee had continued as
      trustee, occurred after the beginning of such four months' period; and

            (ii)  such receipt of property or reduction of claim occurred within
      four months after such resignation or removal.

            (b)   There shall be excluded from the operation of this Section a
creditor relationship arising from

            (1)   the ownership or acquisition of securities issued under any
      indenture, or any security or securities having a maturity of one year or
      more at the time of acquisition by the Trustee;

            (2)   advances authorized by a receivership or bankruptcy court of
      competent jurisdiction or by this Indenture for the purpose of preserving
      any property which shall at any time be subject to the lien of this
      Indenture or of discharging tax liens or other prior liens or encumbrances
      thereon, if notice of such advance and of the circumstances surrounding
      the making thereof is given to the Securityholders at the time and in the
      manner provided in this Indenture;

            (3)   disbursements made in the ordinary course of business in the
      capacity of trustee under an indenture, transfer agent, registrar,

                                                                              43

            (5)   the ownership of stock or of other securities of a corporation

      (c)(4) of this Section.

            (c)   As used in this Section:

            (1)   the term "default" shall mean any failure to make payment in
      full of the principal of or interest upon any of the Securities or upon
      the other indenture securities when and as such principal or interest
      becomes due and payable;

            (2)   the term "other indenture securities" shall mean securities
      upon which the Issuer is an obligor (as defined in the Trust Indenture Act
      of 1939) outstanding under any other indenture (i) under which the Trustee

      possession of, or a lien upon the goods, wares or merchandise or the
      receivables or proceeds arising from the sale of the goods, wares or
      merchandise previously constituting the security, provided the security is
      received by the Trustee simultaneously with the creation of the creditor
      relationship with the Issuer arising from the making, drawing, negotiating

            (5)   the term "Issuer" shall mean any obligor upon the Securities.

                                  ARTICLE VII

                         CONCERNING THE SECURITYHOLDERS

            SECTION 7.1 Evidence of Action Taken by Securityholders. Any
request, demand, authorization, direction, notice, consent, waiver or other
action provided by this Indenture to be given or taken by a specified percentage
in principal amount of the Securityholders of any or all series may be embodied
in and evidenced by one or more instruments of substantially similar tenor
signed by such specified percentage of Securityholders in person or by agent
duly appointed in writing; and, except as herein otherwise expressly
<PAGE>   45
                                                                              44

provided, such action shall become effective when such instrument or instruments
are delivered to the Trustee. Proof of execution of any instruments are
delivered to the Trustee. Proof of execution of any instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Sections 6.1 and 6.2) conclusive in favor of the Trustee and the
Issuer, if made in the manner provided in this Article.

            SECTION 7.2 Proof of Execution of Instruments and of Holding of
Securities. Subject to Sections 6.1 and 6.2, the fact and date of the execution
of any instrument by a Securityholder or his agent or proxy and the amount and
numbers of Securities of any series held by the person so executing any
instrument by a Securityholder or his agent or proxy and the amount and numbers
of any Security or Securities for such series may also be proven in accordance
with such reasonable rules and regulations as may be prescribed by the Trustee
for such series or in any other manner which the Trustee for such series may
deem sufficient.

            SECTION 7.3 Holders to be Treated as Owners. The Issuer, the Trustee
and any agent of the Issuer or the Trustee may deem and treat the person in
whose name any Security shall be registered upon the Security Register for such
series as the absolute owner of such Security (whether or not such Security
shall be overdue and notwithstanding any notation of ownership or other writing
thereon) for the purpose of receiving payment of or on account of the principal
of and, subject to the provisions of this Indenture, interest on such Security
and for all other purposes; and neither the Issuer nor the Trustee nor any agent
of the Issuer or the Trustee shall be affected by any notice to the contrary.
The Issuer, the Trustee and any agent of the Issuer or the Trustee may treat the
Holder of any Unregistered Security and the Holder of any Coupon as the absolute
owner of such Unregistered Security or Coupon (whether or not such Unregistered
Security or Coupon shall be overdue) for the purpose of receiving payment
thereof or on account thereof and for all other purposes and neither the Issuer,
the Trustee, nor any agent of the Issuer or the Trustee shall be affected by any
notice to the contrary. All such payments so made to any such person, or upon
his order, shall be valid, and, to the extent of the sum or sums so paid,
effectual to satisfy and discharge the liability for moneys payable upon any
such Security or Coupon.

            SECTION 7.4 Securities Owned by Issuer Deemed Not Outstanding. In
determining whether the Holders of the requisite aggregate principal amount of
Outstanding Securities of any or all series have concurred in any direction,
consent or waiver under this Indenture, Securities which are owned by the Issuer
or any other obligor on the Securities with respect to which such determination
is being made or by any person directly or indirectly controlling or controlled
by or under direct or indirect common control with the Issuer or any other
obligor on the Securities with respect to which such determination is being made
shall be disregarded and deemed not to be Outstanding for the purpose of any
such determination, except that for the purpose of determining whether the
Trustee shall be protected in relying on any such direction, consent or waiver
only Securities which the Trustee knows are so owned shall be so disregarded.
Securities so owned which have been pledged in good faith may be regarded as
Outstanding if the pledgee establishes to the satisfaction of the Trustee the
pledgee's right so to act with respect to such Securities and that the pledgee
is not the Issuer or any other obligor upon the Securities or any person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Issuer or any other obligor on the Securities. In case
of a dispute as to such right, the advice of counsel shall be full protection in
respect of any decision
<PAGE>   46
                                                                              45

made by the Trustee in accordance with such advice. Upon request of the Trustee,
the Issuer shall furnish to the Trustee promptly an Officers' Certificate
listing and identifying all Securities, if any, known by the Issuer to be owned
or held by or for the account of any of the above-described persons; and,
subject to Sections 6.1 and 6.2, the Trustee shall be entitled to accept such
Officers' Certificate as conclusive evidence of the facts therein set forth and
of the fact that all Securities not listed therein are Outstanding for the
purpose of any such determination.

            SECTION 7.5 Right of Revocation of Action Taken. At any time prior
to (but not after) the evidencing to the Trustee, as provided in Section 7.1, of
the taking of any action by the Holders of the percentage in aggregate principal
amount of the Outstanding Securities of any or all series, as the case may be,
specified in this Indenture in connection with such action, any Holder of a
Security the serial number of which is shown by the evidence to be included
among the serial numbers of the Securities the Holders of which have consented
to such action may, by filing written notice at the Corporate Trust Office and
upon proof of holding as provided in this Article, revoke such action so far as
concerns such Security. Except as aforesaid any such action taken by the Holder
of any Security shall be conclusive and binding upon such Holder and upon all
future Holders and owners of such Security and of any Securities issued in
exchange or substitution therefor, irrespective of whether or not any notation
in regard thereto is made upon any such Security. Any action taken by the
Holders of the percentage in aggregate principal amount of the Securities of any
or all series, as the case may be, specified in this Indenture in connection
with such action shall be conclusively binding upon the Issuer, the Trustee and
the Holders of all the Securities affected by such action.

                                  ARTICLE VIII

                             SUPPLEMENTAL INDENTURES

            SECTION 8.1 Supplemental Indentures Without Consent of
Securityholders. The Issuer, when authorized by a resolution of its Board of
Directors, and the Trustee may from time to time and at any time enter into an
indenture or indentures supplemental hereto (which shall conform to the
provisions of the Trust Indenture Act of 1939 as in force at the date of the
execution thereof) for one or more of the following purposes:

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

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

            (c)   to add to the covenants of the Issuer such further covenants,
      restrictions, conditions or provisions as its Board of Directors and the
      Trustee shall consider to be for the protection of the Holders of
      Securities or Coupons, and to make the occurrence, or the occurrence and
      continuance, of a default in any such additional covenants, restrictions,
      conditions or provisions an Event of Default permitting the enforcement of
      all or any of the several remedies provided in this Indenture as herein
      set forth; provided, that in respect of any such additional covenant,
      restriction, condition or provision such supplemental indenture may
      provide for a particular period of grace after default (which
<PAGE>   47
                                                                              46

      period may be shorter or longer than that allowed in the case of other
      defaults) or may provide for an immediate enforcement upon such an Event
      of Default or may limit the remedies available to the Trustee upon such an
      Event of Default or may limit the right of the Holders of a majority in
      aggregate principal amount of the Securities of affected series to waive
      such an Event of Default;

            (d)   to cure any ambiguity or to correct or supplement any
      provision contained herein or in any supplemental indenture which may be
      defective or inconsistent with any other provision contained herein or in
      any supplemental indenture; or to make such other provisions in regard to
      matters or questions arising under this Indenture or under any
      supplemental indenture as the Board of Directors may deem necessary or
      desirable and which shall not adversely affect the interests of the
      Holders of the Securities;

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

            (f)   to evidence and provide for the acceptance of appointment
      hereunder by a successor trustee with respect to the Securities of one or
      more series and to add to or change any of the provisions of this
      Indenture shall be necessary to provide for or facilitate the
      administration of the trusts hereunder by more than one trustee, pursuant
      to the requirements of Section 6.11.

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

            Any supplemental indenture authorized by the provisions of this
Section may be executed without the consent of the Holders of any of the
Securities at the time outstanding, notwithstanding any of the provisions of
Section 8.2.

            SECTION 8.2 Supplemental Indentures With Consent of Securityholders.
With the consent (evidenced as provided in Article Seven) of the Holders of not
less than a majority in aggregate principal amount of the Securities at the time
Outstanding of all series affected by such supplemental indenture (voting as one
class), the Issuer, when authorized by a resolution of its Board of Directors,
and the Trustee may, from time to time and at any time, enter into an indenture
or indentures supplemental hereto (which shall conform to the provisions of the
Trust Indenture Act of 1939 as in force at the date of execution thereof) for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Indenture or of any supplemental indenture or of
modifying in any manner the rights of the Holders of the Securities of each such
series or the Coupons appertaining to such Securities; provided, that no such
supplemental indenture shall (a) extend the final maturity of any Security, or
reduce the principal amount thereof or the method in which amounts of payments
of principal or interest thereon are determined, or reduce the rate or extend
the time of payment of interest thereon, or change the coin or currency or units
based on or related to currencies (including ECU) of payment thereof, or the
method in which amounts of payments of principal or interest thereon are
<PAGE>   48
                                                                              47

determined, or reduce any amount payable on redemption thereof or reduce the
amount of the principal of an Original Issue Discount Security that would be due
and payable upon an acceleration of the maturity thereof pursuant to Section 5.1
or the amount thereof provable in bankruptcy pursuant to Section 5.2, or impair
or affect or affect the right of any Securityholder to institute suit for the
payment thereof or, if the Securities provide therefor, any right of repayment
at the option of the Securityholder without the consent of the Holder of each
Security so affected, or (b) reduce the aforesaid percentage of Securities of
any series, the consent of the Holders of which is required for any such
supplemental indenture, without the consent of the Holders of each Security so
affected. A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which has expressly been included solely for
the benefit of one or more particular series of Securities or which modifies the
rights of 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 any other series.

            Upon the request of the Issuer, accompanied by a copy of a
resolution of the Board of Directors certified by the secretary or an assistant
secretary of the Issuer authorizing the execution of any such supplemental
indenture, and upon the filing with the Trustee of evidence of the consent of
Securityholders as aforesaid and other documents, if any, required by Section
7.1, the Trustee shall join with the Issuer in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion, but shall not be obligated to, enter
into such supplemental indenture.

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

            Promptly after the execution by the Issuer and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the Issuer
shall mail a notice thereof (i) by first-class mail to the Holders of then
Outstanding Registered Securities of each series affected thereby at their
addresses as they shall appear on the registry books of the Issuer, (ii) if any
Unregistered Securities of a series affected thereby are then Outstanding, to
the Holders thereof who have filed their names and addresses with the Trustee
pursuant to Section 4.4(c)(ii), by mailing a notice thereof by first class mail
to such Holders at such addresses as were so furnished to the Trustee and (iii)
if any Unregistered Securities of a series affected thereby are then
Outstanding, to all Holders thereof, by publication of a notice thereof at least
once in an Authorized Newspaper in the Borough of Manhattan, The City of New
York and at least once in an Authorized Newspaper in London (and, if required by
Section 3.6, at least once in an Authorized Newspaper in Luxembourg), and in
each case such notice shall set forth in general terms the substance of such
supplemental indenture. Any failure of the Issuer to mail such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any such supplemental indenture.

            SECTION 8.3 Effect of Supplemental Indenture. Upon the execution of
any supplemental indenture pursuant to the provisions hereof, this Indenture
shall be and be deemed to be modified and amended in accordance therewith and
the respective rights, limitations of rights, obligations, duties and immunities
under this Indenture of the Trustee, the Issuer and the Holders of Securities of
each series affected thereby shall thereafter be determined, exercised and
<PAGE>   49
                                                                              48

enforced hereunder subject in all respects to such modifications and amendments,
and all the terms and conditions of any such supplemental indenture shall be and
be deemed to be part of the terms and conditions of this Indenture for any and
all purposes.

            SECTION 8.4 Documents to Be Given to Trustee. The Trustee, subject
to the provisions of Sections 6.1 and 6.2, may receive an Officers' Certificate
and an Opinion of Counsel as conclusive evidence that any supplemental indenture
executed pursuant to this Article 8 complies with the applicable provision of
this Indenture.

            SECTION 8.5 Notation on Securities in Respect of Supplemental
Indentures. Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to the provisions of this
Article may bear a notation in form approved by the Trustee for such series as
to any matter provided for by such supplemental indenture or as to any action
taken at any such meeting. If the Issuer or the Trustee shall so determine, new
Securities of any series so modified as to conform, in the opinion of the
Trustee and the Board of Directors to any modification of this Indenture
contained in any such supplemental indenture may be prepared by the Issuer,
authenticated by the Trustee and delivered in exchange for the Securities of
such series then outstanding.

            SECTION 8.6 Waiver of Compliance by Securityholders. Anything in
this Indenture to the contrary notwithstanding, any of the acts which the Issuer
is required to do or is prohibited from doing by any of the provisions of this
Indenture may, to the extent that such provisions might be changed or eliminated
by a supplemental indenture pursuant to Section 8.2 upon consent of holders of a
majority in aggregate principal amount of the Securities at the time
outstanding, be omitted or done by the Issuer, if there is obtained the prior
written consent thereto (evidenced as provided in Article Seven), or the prior
written waiver of compliance with any such provision or provisions, by the
holders of at least a majority of the aggregate principal amount of the
Securities at the time outstanding. The Issuer agrees promptly to file with the
Trustee a duplicate original of each such consent or waiver.

                                   ARTICLE IX

                    CONSOLIDATION, MERGER, SALE OR CONVEYANCE

            SECTION 9.1 Issuer May Consolidate, etc., on Certain Terms. The
Issuer covenants that it will not merge or consolidate with any other
corporation or sell or convey all or substantially all of its assets to any
Person, unless (i) either the Issuer shall be the continuing corporation, or the
successor corporation (if other than the Issuer) shall be a corporation
organized under the laws of the United States of America or any State thereof
and shall expressly assume the due and punctual payment of the principal of and
interest on all the Securities and Coupons, according to their tenor, and the
due and punctual performance and observance of all of the covenants and
conditions of this Indenture to be performed or observed by the Issuer, by
supplemental indenture satisfactory to the Trustee, executed and delivered to
the Trustee by such corporation, and (ii) the Issuer or such successor
corporation, as the case may be, shall not, immediately after such merger or
consolidation, or such sale or conveyance, be in default in the performance of
any such covenant or condition.
<PAGE>   50
                                                                              49

            SECTION 9.2 Successor Corporation to be Substituted. In case of any
such consolidation, merger, sale or conveyance, other than a conveyance by way
of lease, and upon any such assumption by the successor corporation, such
successor corporation shall succeed to and be substituted for the Issuer, with
the same effect as if it had been named herein as the Issuer, and the Issuer
shall thereupon be released from all obligations hereunder and under the
Securities together with any Coupons appertaining thereto and the Issuer as the
predecessor corporation may thereupon or at any time thereafter be dissolved
wound up or liquidated. Such successor corporation thereupon may cause to be
signed, and may issue either in its own name or in the name of J. P. Morgan &
Co. Incorporated any or all of the Securities issuable hereunder together with
any Coupons appertaining thereto which theretofore shall not have been signed by
the Issuer and delivered to the Trustee; and, upon the order of such successor
corporation instead of the Issuer and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee shall authenticate and
shall deliver any Securities together with any Coupons appertaining thereto
which previously shall have been signed and delivered by the officers of the
Issuer to the Trustee for authentication, and any Securities together with any
Coupons appertaining thereto which such successor corporation thereafter shall
cause to be signed and delivered to the Trustee for that purpose. All of the
Securities so issued together with any Coupons appertaining thereto shall in all
respects have the same legal rank and benefit under this Indenture as the
Securities and Coupons theretofore or thereafter issued in accordance with the
terms of this Indenture as though all of such Securities and Coupons had been
issued at the date of the execution hereof.

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

            SECTION 9.3 Opinion of Counsel and Officers' Certificate to Trustee.
The Trustee, subject to the provisions of Sections 6.1 and 6.2, may receive an
Opinion of Counsel and/or an Officers' Certificate, prepared in accordance with
Section 12.5, as conclusive evidence that any such consolidation, merger, sale
or conveyance, and any such assumption complies with the applicable provisions
of Article Nine.

                                   ARTICLE X

                         SUBORDINATION OF THE SECURITIES

            SECTION 10.1 Agreement that the Securities be Subordinated to the
Extent Provided. The Issuer, for itself, its successors and assigns, covenants
and agrees, and each holder of a Note and each holder of any Coupon appertaining
thereto likewise covenants and agrees by his acceptance thereof, that any
payment of principal of and interest on each and all of the Securities is hereby
expressly subordinated, to the extent and in the manner hereinafter set forth,
to the prior payment in full of all Senior Indebtedness of the Issuer.

            SECTION 10.2 Issuer Not to Make Payments with Respect to Securities
in Certain Circumstances. No payment of principal of or interest on the
Securities shall be made and no holder of the Securities or Coupons shall be
entitled to demand or receive any such payment (i) unless all amounts then due
for principal of an interest (including interest accruing subsequent to the
commencement of any proceeding for the bankruptcy or reorganization of the
<PAGE>   51
                                                                              50

Issuer under any applicable bankruptcy, insolvency or similar law now or
hereafter in effect) on all Senior Indebtedness of the Issuer have been paid in
full or duly provided for, or (ii) if, at the time of such payment or
immediately after giving effect thereto, there shall exist with respect to any
such Senior Indebtedness any event of default permitting the holders thereof to
accelerate the maturity thereof or any event which, with notice or lapse of time
or both, would become such an event of default.

            SECTION 10.3 Securities Subordinated to Prior Payment of All Senior
Indebtedness of the Issuer on Dissolution, Liquidation or Reorganization of the
Issuer. Upon any distribution of the assets of the Issuer in connection with
dissolution, winding up, liquidation or reorganization of the Issuer (whether in
bankruptcy, insolvency or receivership proceedings or upon an assignment for the
benefit of creditors or any other marshalling of the assets and liabilities of
the Issuer or otherwise), the holders of Senior Indebtedness of the Issuer shall
first be entitled to receive payment in full in accordance with the terms of
such Senior Indebtedness of the principal thereof and the interest due thereon
(including interest accruing subsequent to the commencement of any proceeding
for the bankruptcy or reorganization of the Issuer under any applicable
bankruptcy, insolvency or similar law now or hereafter in effect) before the
holders of the Securities and Coupons are entitled to receive any payment of the
principal of or interest thereon; and, upon any such dissolution, winding up,
liquidation or reorganization, any payment or distribution of assets of the
Issuer of any kind or character, whether in cash, property or securities, to
which the holders of the Securities or Coupons or the Trustee would be entitled
except for the provisions of this Article, including any such payment or
distribution which may be payable or deliverable by reason of the payment of any
other indebtedness of the Issuer being subordinated to the payment of the
Securities or Coupons, shall be made by the liquidating trustee or agent or
other person making such payment or distribution, whether a trustee in
bankruptcy, a receiver or liquidating trustee or otherwise, directly to the
holders of Senior Indebtedness of the Issuer or their representative or
representatives or to the trustee or trustees under any indenture under which
any instruments evidencing any of such Senior Indebtedness may have been issued,
ratably according to the aggregate amounts remaining unpaid on account of the
principal of and interest (including interest accruing subsequent to the
commencement of any proceeding for the bankruptcy or reorganization of the
Issuer under any applicable bankruptcy, insolvency, or similar law nor or
hereafter in effect) on the Senior Indebtedness of the Issuer held or
represented by each, to the extent necessary to pay in full all such Senior
Indebtedness remaining unpaid, after giving effect to nay concurrent payment or
distribution to the holders of such Senior Indebtedness.

            If the holders of the Securities or Coupons, or any of them, shall
fail to file a proper claim in the form required in any proceeding referred to
in the first paragraph of this Section prior to 30 days before the expiration of
the time to file such claim or claims, and if the Trustee shall likewise fail
prior to 15 days before the expiration of the time to file such claim or claims
pursuant to the authority granted to the Trustee pursuant to the provisions of
Section 5.2, then the holders of Senior Indebtedness of the Issuer are hereby
authorized to file an appropriate claim or claims for and on behalf of the
holders of the Securities and Coupons in the form required in any such
proceeding.

            In the event that, notwithstanding the foregoing, upon any such
dissolution, winding up, liquidation or reorganization, any payment or
distribution of assets of the Issuer of
<PAGE>   52
                                                                              51

any kind or character, whether in cash, property or securities, including any
such payment or distribution which may be payable or deliverable by reason of
the payment of any other indebtedness of the Issuer being subordinated to the
payment of the Securities and Coupons, shall be received by the Trustee or the
holders of the Securities or the Coupons before all Senior Indebtedness of the
Issuer is paid in full, such payment or distribution shall be held in trust for
the benefit of and shall be paid over to the holders of such Senior Indebtedness
or their representative or representatives or to the trustee or trustees under
any indenture under which any instruments evidencing any of such Senior
Indebtedness may have been issued, ratably as aforesaid for application to the
payment of all Senior Indebtedness of the Issuer remaining unpaid until all such
Senior Indebtedness shall have been paid in full, after giving effect to any
concurrent payment or distribution to the holders of such Senior Indebtedness.

            Subject to the payment in full of all Senior Indebtedness of the
Issuer, the holders of the Securities and Coupons shall be subrogated to the
rights of the holders of such Senior Indebtedness to receive payments or
distributions of assets of the Issuer applicable to such Senior Indebtedness
until the Securities and Coupons shall be paid in full and none of the payments
or distributions to the holders of such Senior Indebtedness to which the holders
of the Securities and Coupons or the Trustee would be entitled except for the
provisions of this Article or of payments over, pursuant to the provisions of
this Article, to the holders of such Senior Indebtedness by the holders of the
Securities and Coupons or the Trustee shall, as between the Issuer, its
creditors other than the holders of such Senior Indebtedness and the holders of
the Securities and Coupons, be deemed to be a payment by the Issuer to or on
account of such Senior Indebtedness; it being understood that the provisions of
this Article are and are intended solely for the purpose of defining the
relative rights of the holders of the Securities and Coupons, on the one hand,
and the holders of the Senior Indebtedness of the Issuer, on the other hand.

            The Issuer shall give prompt written notice to the Trustee of any
dissolution, winding up, liquidation or reorganization of the Issuer within the
meaning of this Article. The Trustee shall be entitled to assume that no such
event has occurred unless the Issuer or any one or more holders of Senior
Indebtedness of the Issuer or any trustee therefor has given written notice
thereof to the Trustee at its corporate trust office. Upon any distribution of
assets of the Issuer referred to in this Article, the Trustee and the holders of
the Securities and Coupons shall be entitled to rely upon any order or decree of
a court of competent jurisdiction in which such dissolution, winding up,
liquidation or reorganization proceedings are pending for the purpose of
ascertaining the persons entitled to participate in such distribution, the
holders of the Senior Indebtedness of the Issuer, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article, and the Trustee and the holders of the
Securities and Coupons shall be entitled to rely upon a certificate of the
liquidating trustee or agent or other person making any distribution to the
Trustee or to the holders of the Securities and Coupons for the purpose of
ascertaining the persons entitled to participate in such distribution, the
holders of the Senior Indebtedness of the Issuer, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article. 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 Senior Indebtedness of the Issuer, to participate in
any payment or distribution pursuant to this Section, the Trustee may request
such person to furnish evidence to the reasonable satisfaction of the Trustee as
to the amount of such Senior Indebtedness held by such person, as to the extent
to which such person is entitled to
<PAGE>   53
                                                                              52

participation in such payment or distribution, and as to other facts pertinent
to the rights of such person under this Section, 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.

            SECTION 10.4 Obligation of the Issuer Unconditional. Nothing
contained in this Article or elsewhere in this Indenture or in the Securities is
intended to or shall impair as between the Issuer and the holders of the
Securities and Coupons, the obligation of the Issuer, which is absolute and
unconditional, to pay to the holders of the Securities or Coupons the principal
of and interest (including interest accruing subsequent to the commencement of
any proceeding for the bankruptcy or reorganization of the Issuer under any
applicable bankruptcy, insolvency or similar law now or hereafter effect) on the
Securities as and when the same shall become due and payable in accordance with
the terms thereof, or is intended to or shall affect the relative rights of the
holders of he Securities and Coupons and creditors of the Issuer other than the
holders of the Senior Indebtedness of the Issuer, nor shall anything herein or
therein prevent the Trustee or the holder of any Security or Coupon from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, under this Article of the holders
of Senior Indebtedness of the Issuer in respect of cash, property or securities
of the Issuer received upon the exercise of any such remedy.

            SECTION 10.5 No Fiduciary Duty to Holders of Senior Indebtedness of
the Issuer. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness of the Issuer, except as provided in Section
10.3.

            SECTION 10.6 Notice to Trustee of Facts Prohibiting Payments.
Notwithstanding any of the provisions of this Article or any other provision of
this Indenture, the Trustee shall not at any time be charged with knowledge of
the existence of any facts which would prohibit the making of any payment of
moneys to or by the Trustee, unless and until the Trustee shall have received at
its corporate trust office written notice thereof from the Issuer or from one or
more holders of Senior Indebtedness of the Issuer or from any trustee therefor
who shall have been certified by the Issuer or otherwise established to the
reasonable satisfaction of the Trustee to be such a holder or trustee; and,
prior to the receipt of any such written notice, the Trustee shall be entitled
in all respects to assume that no such facts exist; provided, that, if prior to
the fifth business day preceding the date upon which by the terms hereof any
such moneys may become payable for any purpose, or in the event of the execution
of an instrument pursuant to Section 11.1 acknowledging satisfaction and
discharge of this Indenture, then if prior to the second business day preceding
the date of such execution the Trustee shall not have received with respect to
such moneys the notice provided for in this Section, then, anything herein
contained to the contrary notwithstanding, the Trustee may, in its discretion,
receive such moneys and 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 date; provided, however, no such application
shall affect the obligations under this Article of the persons receiving such
moneys from the Trustee. In any case, the Trustee shall have no responsibility
to holders of Senior Indebtedness for payments made to holders of Securities by
the Issuer, the Transfer Agent or any paying agent unless such payments are made
at the direction of the Trustee.

                                                                              53

            SECTION 10.7 Application by Trustee of Moneys Deposited with It.
Anything in this Indenture to the contrary notwithstanding, any deposit of
moneys by the Issuer with the Trustee, any transfer agent or any paying agent
(whether or not in trust) for the payment of the principal of or interest on any
Securities shall, except as provided in Section 10.6, be subject to the
provisions of Sections 10.1, 10.2 and 10.3.

            SECTION 10.8 Subordination Rights Not Impaired by Acts or Omissions
of the Issuer or Holders of Senior Indebtedness of the Issuer. No right of any
present or future holders of any Senior Indebtedness of the Issuer to enforce
subordination as herein provided shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Issuer or by any act or
failure to act, in good faith, by any such holder, or by any noncompliance by
the Issuer with the terms, provisions and covenants of this Indenture,
regardless of any knowledge thereof which any such holder may have or be
otherwise charged with. The holders of Senior Indebtedness of the Issuer may at
any time or from time to time and in their absolute discretion, change the
manner, place or terms of payment, change or extend the time of payment of, or
renew or alter, any such Senior Indebtedness, or amend or supplement any
instrument pursuant to which any such Senior Indebtedness is issued or by which
it may be secured, or release any security therefor, or exercise or refrain from
exercising any other of their rights under the Senior Indebtedness of the Issuer
including, without limitation, the waiver of default thereunder, all without
notice to or assent from the holders of the Securities or Coupons or the Trustee
and without affecting the obligations of the Issuer, the Trustee or the holders
of the Securities or Coupons under this Article.

the Securities. Each holder of a Security and each holder of any Coupon
appertaining thereto, by his acceptance thereof, authorizes and expressly
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article. If, in the
event of any dissolution, winding up, liquidation or reorganization of the
Issuer (whether in bankruptcy, insolvency or receivership proceedings or upon an
assignment for the benefit of creditors or otherwise) tending towards
liquidation of the business and assets of the Issuer, a proper claim or proof of
debt in the form required in such proceeding is not filed by or on behalf of the
holders of the Securities and Coupons prior to 30 days before the expiration of
the time to file such claim or claims, then the holder or holders of Senior
Indebtedness of the Issuer are hereby authorized to and have the right to file
and are hereby authorized to file an appropriate claim for an don behalf of the
holders of the Securities and Coupons.

            SECTION 10.10 Right of Trustee to Hold Senior Indebtedness of the
Issuer. The Trustee shall be entitled to all of the rights set forth in this
Article in respect of any Senior Indebtedness of the Issuer at any time held by
it to the same extent as any other holder of such Senior Indebtedness, and
nothing in this Indenture shall be construed to deprive the Trustee of any of
its rights as such holder.

            SECTION 10.11 Article Ten Not to Prevent Events of Default. The
failure to make a payment pursuant to the Securities by reason of any provision
in this Article shall not be construed as preventing the occurrence of an Event
of Default under Section 5.1.

(a) the Issuer shall have paid or caused to be paid the principal of and
interest on all the Securities theretofore authenticated hereunder and all
unmatured Coupons appertaining thereto (other than Securities and Coupons
appertaining thereto which have been destroyed, lost or stolen and which have
been replaced or paid as provided in Section 2.9 and other than Securities for
whose payment money has theretofore been deposited in trust or segregated and
held in trust by any paying agent and thereafter repaid to the Issuer or
discharged from such trust, as provided in Section 11.4), as and when the same
shall have become due and payable, or (b) the Issuer shall have delivered to the
Trustee of cancellation all Securities of any series theretofore authenticated
and all unmatured Coupons appertaining thereto (other than any Securities of
such series and all unmatured Coupons appertaining thereto which shall have been
destroyed, lost or stolen and which shall have been replaced or paid as provided
in Section 2.9) or (c) (i) all the Securities of any series and all unmatured
Coupons appertaining thereto not heretofore delivered to the Trustee for
cancellation shall have become due and payable, or are by their terms to become
due and payable within one year or are to be called for redemption within one
year under arrangements satisfactory to the Trustee for the giving of notice of
redemption, and (ii) the Issuer shall have irrevocably deposited or caused to be
deposited with the Trustee as trust funds the entire amount in cash (other than
moneys repaid by the Trustee or any paying agent to the Issuer in accordance

interest due or to become due to such date of maturity as the case may be, and
if, in any such case, the Issuer shall also pay or cause to be paid all other

and Coupons appertaining thereto, then this Indenture shall cease to be of
further effect with respect to Securities of such series (except as to (i)
rights of registration of transfer and exchange, and the Issuer's right of
optional redemption, (ii) substitution of mutilated, defaced, destroyed, lost or
stolen Securities or Coupons, (iii) rights of holders to receive payments of
principal thereof and interest thereon, and remaining rights of the Holders to
receive mandatory sinking fund payments, if any, (iv) the rights, obligations
and immunities of the Trustee hereunder and (v) the rights of the Holders of
Securities of such series and Coupons appertaining thereto, as beneficiaries
hereof with respect to the property so deposited with the Trustee payable to all
or any of them), and the Trustee, on demand of the Issuer accompanied by an
Officers' Certificate and an Opinion of Counsel and at the cost and expense of
the Issuer, shall execute proper instruments acknowledging such satisfaction of
and discharging this Indenture with respect to such series; provided, that the
rights of holders of the Securities and Coupons to receive amounts in respect of
principal of and interest on the Securities and Coupons held by them shall not
be delayed longer than required by then applicable mandatory rules or policies
of any securities exchange upon which the Securities and Coupons are listed. The
Issuer agrees to reimburse the Trustee for any costs or expenses thereafter
reasonably and properly incurred and to compensate the Trustee for any services
thereafter reasonably and properly rendered by the Trustee in connection with
this Indenture or the Securities and Coupons of such series.

acting as its own paying agent), to the Holders of the particular Securities of
such series and of Coupons appertaining thereto for the payment or redemption of
which such moneys have been deposited with the Trustee, of all sums due and to
become due thereon for principal and interest; but such money need not be
segregated from other funds except to the extent required by law.

            SECTION 11.3 Repayment of Moneys Held by Paying Agent. In connection
with the satisfaction and discharge of this Indenture with respect to Securities
of any series, all moneys then held by any paying agent under the provisions of
this Indenture with respect to such series of Securities shall, upon demand of
the Issuer, be repaid to it or paid to the Trustee and thereupon such paying
agent shall be released from all further liability with respect to such moneys.

            SECTION 11.4 Return of Moneys Held by Trustee and Paying Agent
Unclaimed for Three Years. Any moneys deposited with or paid to the Trustee or
any paying agent for the payment of the principal of or interest on any Security
of any series or Coupons attached thereto and not applied but remaining

shall have become due and payable, shall, upon the written request of the Issuer
and unless otherwise required by mandatory provisions of applicable escheat or
abandoned or unclaimed property law, be repaid to the Issuer by the Trustee for
such series and/or such paying agent, and the Holder of the Security of such
series and of any Coupons appertaining thereto, shall, unless otherwise required
by mandatory provisions of applicable escheat or abandoned or unclaimed property
laws, thereafter look only to the Issuer for any payment which such Holder may
be entitled to collect, and all liability of the Trustee or any paying agent
with respect to such moneys shall thereupon cease; provided, the Trustee or such
paying agent, before being required to make any such repayment, with respect to
moneys deposited with it for any payment (a) in respect of Registered Securities
of any series, shall at the expense of the Issuer, mail by first-class mail to
Holders of such Securities at their addresses as they shall appear on the

            SECTION 12.1 Incorporators, Stockholders, Officers and Directors of
Issuer Exempt from Individual Liability. No recourse under or upon any
obligation, covenant or agreement contained in this Indenture, or in any
Security, or because of any indebtedness evidenced thereby, shall be had against

officer or director, as such, of the Issuer or of any successor, either directly
or
<PAGE>   57
                                                                              56

through the Issuer or any successor, under any rule of law, statute or
constitutional provision or by the enforcement of any assessment or by any legal
or equitable proceeding or otherwise, all such liability being expressly waived
and released by the acceptance of the Securities and the Coupons appertaining
thereto by the holders thereof and as part of the consideration for the issue of
the Securities and the Coupons appertaining thereto.

            SECTION 12.2 Provisions of Indenture for the Sole Benefit of Parties
and Holders of Securities and Coupons. Nothing in this Indenture or in the
Securities or in the Coupons appertaining thereto, expressed or implied, shall
give or be construed to give to any person, firm or corporation, other than the
parties hereto and their successors and the holders of the Securities and the
Coupons appertaining thereto, and, to the extent provided in Article 10, to the
holders of Senior Indebtedness any legal or equitable right, remedy or claim
under this Indenture or under any covenant or provision herein contained, all
such covenants and provisions being for the sole benefit of the parties hereto
and their successors and of the holders of the Securities and the Coupons, and,
to the extent provided in Article 10, to the holders of Senior Indebtedness.

            SECTION 12.3 Successors and Assigns of Issuer Bound by Indenture.
All the covenants, stipulations, promises and agreements in this Indenture
contained by or in behalf of the Issuer shall bind its successors and assigns,
whether so expressed or not.

            SECTION 12.4 Notices and Demands on Issuer, Trustee and Holders of
Securities and Coupons. Any notice or demand which by any provision of this
Indenture is required or permitted to be given or served by the Trustee or by
the Holders of Securities or Coupons to or on the Issuer may be given or served
by being deposited postage prepaid, first class mail (except as otherwise
specifically provided herein) addressed (until another address of the Issuer is
filed by the Issuer with the Trustee) to J.P. Morgan & Co. Incorporated, 23 Wall

request or demand by the Issuer or any holder of Securities and Coupons to or

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

            In case, by reason of the suspension of or irregularities in regular
mail service, it shall be impracticable to mail notice to the Issuer and when
such notice is required to be given pursuant to any provision of this Indenture,
then any manner of giving such notice as shall be satisfactory to the Trustee
shall be deemed to be a sufficient giving of such notice.

the Issuer shall furnish to the Trustee an Officers' Certificate stating that
all conditions precedent provided for in this Indenture relating to the proposed
action have been complied with and an Opinion of Counsel stating that in the

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

control.

            SECTION 12.8 New York Law to Govern. This Indenture and each

purposes shall be construed in accordance with the laws of such State, except as
may otherwise be required by mandatory provisions of law.

            SECTION 12.9 Counterparts. This Indenture may be executed in any
number of counterparts, each of which shall be an original; but such
counterparts shall together constitute but one and the same instrument.

            SECTION 12.10 Effect of Headings. The Article and Section headings

the construction hereof.

            SECTION 12.11 Securities in a Foreign Currency or in ECU. Unless
otherwise specified in an Officer's Certificate delivered pursuant to Section
2.3 of this Indenture with respect to a particular series of Securities,
whenever for purposes of this Indenture any action may be taken by the holders
of a specified percentage in aggregate principal amount of Securities of all
series or all series affected by a particular action at the time Outstanding
and, at such time, there are Outstanding Securities of any series which are
denominated in a coin or currency other than Dollars (including ECUs), then the
principal amount of Securities of such series which shall be deemed to be
Outstanding for the purpose of taking such action shall be that amount of
Dollars that could be obtained for such amount at the Market Exchange Rate. For
purposes of this Section 11.11, Market Exchange Rate shall mean the noon Dollar
buying rate for that currency for cable transfers quoted in The City of New York
as certified for customs purposes by the Federal Reserve Bank of New York;
provided, however, in the case of ECUs, Market Exchange Rate shall mean the rate
of exchange determined by the Commission of the European Communities (or any
successor thereto) as published in the Official Journal of the European
Communities (such publication or any successor publication, the "Journal"). If
such Market Exchange Rate is not available for any reason with respect to such
currency, the Trustee shall use, in its sole discretion and without liability on
its part, such quotation of the Federal Reserve Bank of New York or, in the case
of ECUs, the rate of exchange as published in the Journal, as of the most recent
available date, or quotations or, in the case of ECUs, rates of exchange from
one or more major banks in The City of New York or in the country of issue of
the currency in question, which for purposes of the ECU shall be Brussels,
Belgium, or such other quotations or, in the case of ECU, rates of exchange as
the Trustee shall deem appropriate. The provisions of this paragraph shall apply
in determining the equivalent principal amount in respect of Securities of a
series denominated in a currency other than Dollars in connection with any
action taken by holders of Securities pursuant to the terms of this Indenture.

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

            SECTION 13.1 Applicability of Article. The provisions of this
Article shall be applicable to the Securities of any series which are redeemable
before their maturity or to any
<PAGE>   60
                                                                              59

sinking fund for the retirement of Securities of a series except as otherwise
specified as contemplated by Section 2.3 for Securities of such series.

            SECTION 13.2 Notice of Redemption; Partial Redemptions. Notice of
redemption to the holders of Registered Securities of any series to be redeemed
as a whole or in part at the option of the Issuer shall be given by mailing
notice of such redemption by first class mail, postage prepaid, at least 30 days
and not more than 60 days prior to the date fixed for redemption to such holders
of Securities of such series at their last addresses as they shall appear upon
the registry books. Notice of redemption to the Holders of Unregistered
Securities to be redeemed as a whole or in part, who have filed their names and
addresses with the Trustee pursuant to Section 4.4(c)(ii), shall be given by
mailing notice of such redemption, by first class mail, postage prepaid, at
least thirty days and not more than sixty prior to the date fixed for
redemption, to such Holders at such addresses as were so furnished to the
Trustee (and, in the case of any such notice given by the Issuer, the Trustee
shall make such information available to the Issuer for such purpose). Notice of
redemption to all other holders of Unregistered Securities shall be published in
an Authorized Newspaper in the Borough of Manhattan, The City of New York and in
an Authorized Newspaper in London (and, if required by Section 3.6, in an
Authorized Newspaper in Luxembourg), in each case, once in each of three
successive calendar weeks, the first publication to be not less than thirty nor
more than sixty days prior to the date fixed for redemption. Any notice which is
mailed in the manner herein provided shall be conclusively presumed to have been
duly given, whether or not the holder receives the notice. Failure to give
notice by mail, or any defect in the notice to the Holder of any Security of a
series designated for redemption as a whole or in part shall not affect the
validity of the proceedings for the redemption of any other Security of such
series.

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

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

            At least one Business Day prior to the redemption date specified in
the notice of redemption given as provided in this Section, the Issuer will
deposit with the Trustee or with one or more paying agents (or, if the Issuer is
acting as its own paying agent, set aside, segregate and
<PAGE>   61
                                                                              60

hold in trust as provided in Section 3.4) an amount of money sufficient to
redeem on the redemption date all the Securities of such series so called for
redemption at the appropriate redemption price, together with accrued interest
to the date fixed for redemption. If less than all the outstanding Securities of
a series are to be redeemed, the Issuer will deliver to the Trustee at least 60
days prior to the date fixed for redemption an Officers' Certificate stating the
aggregate principal amount of Securities to be redeemed.

            If less than all the Securities of a series are to be redeemed, the
Trustee shall select, in such manner as it shall deem appropriate and fair,
Securities of such series to be redeemed in whole or in part. Securities may be
redeemed in part in multiples equal to the minimum authorized denomination for
Securities of such series or any multiple thereof. The Trustee shall promptly
notify the Issuer in writing of the Securities of such series selected for
redemption and, in the case of any Securities of such series selected for
partial redemption, the principal amount thereof to be redeemed. For all
purposes of this Indenture, unless the context otherwise requires, all
provisions relating to the redemption of Securities of any series shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.

            SECTION 13.3 Payment of Securities Called for Redemption. If notice
of redemption has been given as above provided, the Securities or portions of
Securities specified in such notice shall become due and payable on the date and
at the place stated in such notice at the applicable redemption price, together
with interest accrued to the date fixed for redemption, and on and after said
date (unless the Issuer shall default in the payment of such Securities at the
redemption price, together with interest accrued to said date) interest on the
Securities or portions of Securities so called for redemption shall cease to
accrue and the unmatured Coupons, if any, appertaining thereto shall be void
and, except as provided in Sections 6.5 and 11.4, such Securities shall cease
from and after the date fixed for redemption to be entitled to any benefit or
security under this Indenture, and the holders thereof shall have no right in
respect of such Securities except the right to receive the redemption price
thereof and unpaid interest to the date fixed for redemption. On presentation
and surrender of such Securities at a place of payment specified in said notice,
together with all Coupons, if any, appertaining thereto maturing after the date
fixed for redemption, said Securities with, in the case of any Unregistered
Securities that have Coupons attached, all matured Coupons in default
appertaining thereto or the specified portions thereof shall be paid and
redeemed by the Issuer at the applicable redemption price, together with
interest accrued thereon to the date fixed for redemption; provided that any
payment of interest becoming due on the date fixed for redemption shall be
payable in the case of Securities with Coupons attached thereto, to the bearers
of the Coupons for such interest upon surrender thereof, and in the case of
Registered Securities to the Holders of such Securities registered as such on
the relevant record date subject to the terms and provisions of Section 2.4
hereof.

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

            If any Security with Coupons attached thereto is surrendered for
redemption and is not accompanied by all appurtenant Coupons maturing after the
date fixed for redemption, the
<PAGE>   62
                                                                              61

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

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

            SECTION 13.4 Exclusion of Certain Securities from Eligibility for
Selection for Redemption. Securities shall be excluded from eligibility for
selection for redemption if they are identified by registration and certificate
number in a written statement signed by an authorized officer of the Issuer and
delivered to the Trustee at least 30 days prior to the last date on which notice
of redemption may be given as being owned of record and/or beneficially by, and
not pledged or hypothecated by either (a) the Issuer or (b) an entity
specifically identified in such written statement directly or indirectly
controlling or controlled by or under direct or indirect common control with the
Issuer.

            SECTION 13.5 Mandatory and Optional Sinking Funds. The minimum
amount of any sinking fund payment provided for by the terms of Securities of
any series is herein referred to as a "mandatory sinking fund payment", and any
payment in excess of such minimum amount provided for by the terms of Securities
of any series is herein referred to as an "optional sinking fund payment". The
date on which a sinking fund payment is to be made is herein referred to as the
"sinking fund payment date".

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

            On or before the sixtieth day next preceding each sinking fund
payment date for any series, the Issuer will deliver to the Trustee a written
statement (which need not contain the statements required by Section 12.5)
signed by either the chairman of the Board of Directors, the president, the
chairman of the executive committee, any vice chairman of the Board of
Directors, any vice president, the treasurer, any assistant treasurer, the
secretary or any assistant secretary of the Issuer (a) specifying the portion of
the mandatory sinking fund payment to be satisfied by payment of cash and the
portion to be satisfied by credit of Securities of such series, (b) stating that
none of the Securities of such series has theretofore been so credited, (c)
stating that no defaults in the payment of interest or Events of Default with
respect to such series have occurred
<PAGE>   63
                                                                              62

(which have not been waived or cured) and are continuing and (d) stating whether
or not the Issuer intends to exercise its right to make an optional sinking fund
payment with respect to such series and, if so, specifying the amount of such
optional sinking fund payment which the Issuer intends to pay on or before the
next succeeding sinking fund payment date. Any Securities of such series to be
credited and required to be delivered to the Trustee in order for the Issuer to
be entitled to credit therefore as aforesaid which have not theretofore been
delivered to the Trustee shall be delivered for cancellation pursuant to Section
2.10 to the Trustee with such written statement. Such written statement shall be
irrevocable and upon its delivery the Issuer shall become unconditionally
obligated to make all the cash payments or payments therein referred to, if any,
on or before the next succeeding sinking fund payment date. Failure of the
Issuer, on or before any such sixtieth day, to deliver such written statement
and Securities specified in this paragraph, if any, shall not constitute a
default but shall constitute, on and as of such date, the irrevocable election
of the Issuer (i) that the mandatory sinking fund payment for such series due on
the next succeeding sinking fund payment date shall be paid entirely in cash
without the option to deliver or credit Securities of such series in respect
thereof and (ii) that the Issuer will make no optional sinking fund payment with
respect to such series as provided in this Section.

            If the sinking fund payment or payments (mandatory or optional or
both) to be made in cash on the next succeeding sinking fund payment date plus
any unused balance of any preceding sinking fund payments made in cash shall
exceed $50,000 (or a lesser sum if the Issuer shall so request) with respect to
the Securities of any particular series, such cash shall be applied on the next
succeeding sinking fund payment date to the redemption of Securities of such
series at the sinking fund redemption price together with accrued interest to
the date fixed for redemption. If such amount shall be $50,000 or less and the
Issuer makes no such request then it shall be carried over until a sum in excess
of $50,000 is available. The Trustee shall select, in the manner provided in
Section 13.2, for redemption on such sinking fund payment date a sufficient
principal amount of Securities of such series to absorb said cash, as nearly as
may be, and shall (if requested in writing by the Issuer) inform the Issuer of
the serial numbers of the Securities of such series (or portions thereof) so
selected. Securities of any series which are (a) owned by the Issuer or an
entity known by the Trustee to be directly or indirectly controlling or
controlled by or under direct or indirect common control with the Issuer, as
shown by the Security Register, and not known to the Trustee to have been
pledged or hypothecated by the Issuer or any such entity or (b) identified in an
Officers' Certificate at least 60 days prior to the sinking fund payment date as
being beneficially owned by, and not pledged or hypothecated by, the Issuer or
an entity directly or indirectly controlling or controlled by or under direct or
indirect common control with the Issuer shall be excluded from Securities of
such series eligible for selection for redemption. The Trustee, in the name and
at the expense of the Issuer (or the Issuer, if it shall so request the Trustee
in writing) shall cause notice of redemption of the Securities of such series to
be given in substantially the manner provided in Section 13.2 (and with the
effect provided in Section 13.3) for the redemption of Securities of such series
in part at the option of the Issuer. The amount of any sinking fund payments not
so applied or allocated to the redemption of Securities of such series shall be
added to the next cash sinking fund payment for such series and, together with
such payment, shall be applied in accordance with the provisions of this
Section. Any and all sinking fund moneys held on the stated maturity date of the
Securities of any particular series (or earlier, if such maturity is
accelerated), which are not held for the payment or redemption of particular
Securities of such series shall be applied,
<PAGE>   64
                                                                              63

together with other moneys, if necessary, sufficient for the purpose, to the
payment of the principal of, and interest on, the Securities of such series at
maturity.

            At least one Business Day before each sinking fund payment date, the
Issuer shall pay to the Trustee in cash or shall otherwise provide for the
payment of all interest accrued to the date fixed for redemption on Securities
to be redeemed on the next following sinking fund payment date.

            The Trustee shall not redeem or cause to be redeemed any Securities
of a series with sinking fund moneys or provide notice of redemption of
Securities for such series by operation of the sinking fund during the
continuance of a default in payment of interest on such Securities or of any
Event of Default except that, where the mailing or publication of notice of
redemption of any Securities shall theretofore have been made, the Trustee shall
redeem or cause to be redeemed such securities, provided that it shall have
received from the Issuer a sum sufficient for such redemption. Except as
aforesaid, any moneys in the sinking fund for such series at the time when any
such default or Event of Default shall occur, and any moneys thereafter paid
into the sinking fund, shall, during the continuance of such default or Event of
Default, be deemed to have been collected under Article Five and held for the
payment of all such Securities. In case such Event of Default shall have been
waived as provided in Section 5.10 or the default cured on or before the
sixtieth day preceding the sinking fund payment date in any year, such moneys
shall thereafter be applied on the next succeeding sinking fund payment date in
accordance with this Section to the redemption of such Securities.
