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

         (6) The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided that the
Company may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date, provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
(as defined below) by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Company from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Company, at its own expense, shall cause notice
of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Trustee in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 1.6.

         The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 5.2, (iii) any request to institute
proceedings referred to in Section 5.7(2) or (iv) any direction referred to in
Section 5.12, in each case with respect to Securities of such series. If

                                       14
<PAGE>   21

any record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date, provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Trustee, at the Company's expense, shall cause
notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 1.6.

         With respect to any record date set pursuant to this Section, the party
hereto which sets such record dates may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day, provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 1.6, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph.

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

         SECTION 1.5. Notices, etc. to Trustee and Company.

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

         (1) the Trustee by any Holder, any holder of Preferred Securities or
the Company shall be sufficient for every purpose hereunder if made, given,
furnished or filed in writing to or with the Trustee at its Corporate Trust
Office, Attention: Corporate Trust and Agency Group--Capital Market Services, or

         (2) the Company by the Trustee, any Holder or any holder of Preferred
Securities shall be sufficient for every purpose (except as otherwise provided
in Section 5.1) hereunder if in writing and mailed, first class, postage
prepaid, to the Company addressed to it at 2929 Allen Parkway, Houston, TX
77019-2155, Attention: Treasurer or at any other address previously furnished in
writing to the Trustee by the Company.

         SECTION 1.6. Notice to Holders; Waiver.

         Except as otherwise expressly provided in or pursuant to the provisions
of this Indenture, where this Indenture provides for notice to Holders of any
event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first class postage prepaid, to
each Holder affected by such event, at the address of such Holder as it appears
in the Securities Register, not later than the latest date, and not earlier than
the earliest date, prescribed for the giving of such notice. 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.

         SECTION 1.7. Conflict with Trust Indenture Act.

         If any provision of this Indenture limits, qualifies or conflicts with
the duties imposed by any of Sections 310 to 317, inclusive, of the Trust
Indenture Act through operation of Section 318(c) thereof, such imposed duties
shall control.

invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

         No provision of this Indenture or of any Security shall require the
payment or permit the collection of interest (including any Additional Interest)
in excess of the maximum which is not prohibited by law. If any such excess
interest is provided for herein or in any Security, which shall be adjudicated
to be so provided for, then the Company shall not be obligated to pay such
interest in excess of the maximum not prohibited by law until such time, if any,
as it shall become legal to do so.

         SECTION 1.11. Benefits of Indenture.

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

have the right, as such a holder, to enforce any other provision of this
Indenture.

         SECTION 1.13. Non-Business Days.

Maturity of any Security shall not be a Business Day, then (notwithstanding any
other provision of this Indenture or the Securities other than a provision in
the Securities of any series which specifically states that such provision shall
apply in lieu of this Section) payment of interest (including any Additional

Day is in the next succeeding calendar year, such payment shall be made on the

         SECTION 3.2. Denominations.

         The Securities of each series shall be in registered form without
coupons and shall be issuable in denominations of $1,000 and any integral
multiple thereof, unless otherwise specified as contemplated by Section 3.1.

         SECTION 3.3. Execution, Authentication, Delivery and Dating.

Chairman, its Vice Chairman, its President or one of its Vice Presidents under
its corporate seal reproduced thereon by and attested by its Treasurer or
Secretary or one of its Assistant Treasurers or Assistant Secretaries. The
signature of any of these officers on the Securities may be manual or facsimile.

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

time after the execution and delivery of this Indenture, the Company may deliver
Securities of any series executed by the Company to the Trustee for

Order shall authenticate and deliver such Securities. If the form or terms of
the Securities of the series have been established by or pursuant to one or more
Board Resolutions as permitted by Sections 2.1 and 3.1, in authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities, the Trustee shall be entitled to receive, and
(subject to Section 6.1) shall be fully protected in relying upon, an Opinion of
Counsel stating that:

         (1) the form and terms of such Securities, or the manner of determining
such terms, have been established in conformity with the provisions of this
Indenture; and

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


                                       25
<PAGE>   32


         If such form or terms have been so established, the Trustee shall not
be required to authenticate such Securities if the issuance of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

         Notwithstanding the provisions of Section 3.1 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 3.1 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose, unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by the manual signature of one of its authorized
officers, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder. Notwithstanding the foregoing, if any Security shall have
been authenticated and delivered hereunder but never issued and sold by the
Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 3.9, for all purposes of this Indenture such
Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

         SECTION 3.4. Temporary Securities.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, in the manner provided in Section 3.3, temporary Securities which are
printed, lithographed, typewritten, mimeographed or otherwise produced, in any
denomination, substantially of the tenor of the definitive Securities of such
series in lieu of which they are issued and with such appropriate insertions,
omissions, substitutions and other variations as the officers executing such
Securities may determine, as evidenced by their execution of such Securities.
Such temporary securities may be in global form.

         If temporary Securities of any series are issued, the Company will
cause definitive Securities of such series to be prepared without unreasonable
delay. After the preparation of

                                       26
<PAGE>   33

definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities of such series, containing identical terms and provisions,
upon surrender of the temporary Securities at the office or agency of the
Company designated for that purpose without charge to the Holder. Upon surrender
for cancellation of any one or more temporary Securities, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
like aggregate principal amount of definitive Securities of the same series, of
any authorized denominations having the same Original Issue Date and Stated
Maturity and having the same terms as such temporary Securities. Until so
exchanged, the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

         SECTION 3.5. Registration, Transfer and Exchange.

         The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of Securities and of
transfers of Securities. Such register is herein sometimes referred to as the
"Securities Register." The Trustee is hereby appointed "Securities Registrar"
for the purpose of registering Securities and transfers of Securities as herein
provided.

         Upon surrender for registration of transfer of any Security at the
office or agency of the Company designated for that purpose, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of the same
series of any authorized denominations, of a like aggregate principal amount, of
the same Original Issue Date and Stated Maturity and having the same terms.

         At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series of any authorized denominations, of a
like aggregate principal amount, of the same Original Issue Date and Stated
Maturity and having the same terms, upon surrender of the Securities to be
exchanged at such office or agency. Whenever any securities are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.

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


                                       27
<PAGE>   34


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

         No service charge shall be made to a Holder for any transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Securities.

         The provisions of Clauses (1), (2), (3) and (4) below shall apply only
to Global Securities:

         (1) Each Global Security authenticated under this Indenture shall be
registered in the name of the Depository designated for such Global Security or
a nominee thereof and delivered to such Depository or a nominee thereof or
custodian therefor, and each such Global Security shall constitute a single
Security for all purposes of this Indenture.

         (2) Notwithstanding any other provision in this Indenture, no Global
Security may be exchanged in whole or in part for Securities registered, and no
transfer of a Global Security in whole or in part may be registered, in the name
of any Person other than the Depository for such Global Security or a nominee
thereof unless (A) such Depository (i) has notified the Company that it is
unwilling or unable to continue as Depository for such Global Security or (ii)
has ceased to be a clearing agency registered under the Exchange Act at a time
when the Depository is required to be so registered to act as depository, in
each case unless the Company has approved a successor Depository within 90 days,
(B) there shall have occurred and be continuing an Event of Default with respect
to such Global Security, (C) the Company in its sole discretion determines that
such Global Security will be so exchangeable or transferable or (D) there shall
exist such circumstances, if any, in addition to or in lieu of the foregoing as
have been specified for this purpose as contemplated by Section 3.1.

         (3) Subject to Clause (2) above, any exchange of a Global Security for
other Securities may be made in whole or in part, and all Securities issued in
exchange for a Global Security or any portion thereof shall be registered in
such names as the Depository for such Global Security shall direct.

         (4) Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Security or any portion
thereof, whether pursuant to this Section, Section 3.4, 3.6, 9.6 or 11.6 or
otherwise, shall be

                                       28
<PAGE>   35

authenticated and delivered in the form of, and shall be, a Global Security,
unless such Security is registered in the name of a Person other than the
Depository for such Global Security or a nominee thereof.

         Except as otherwise provided in or pursuant to this Indenture, the
Company shall not be required (i) to issue, register the transfer of or exchange
Securities of any series during a period beginning at the opening of business 15
days before the day of the selection for redemption of Securities of like tenor
and the same series under Section 11.3 or Article XII and ending at the close of
business on the day of the mailing of the relevant notice of redemption, (ii) to
register the transfer of or exchange any Security so selected for redemption in
whole or in part, except, in the case of any Security to be redeemed in part,
the portion thereof not to be redeemed or (iii) to issue, register the transfer
of or exchange any Security which, in accordance with its terms, has been
surrendered for repayment at the option of the Holder, except the portion, if
any, of such Security not to be so repaid.

         SECTION 3.6. Mutilated, Destroyed, Lost and Stolen Securities.

         If any mutilated Security is surrendered to the Trustee together with
such security or indemnity as may be required by the Company or the Trustee to
save each of them harmless, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a new Security of the same issue
and series of like tenor and principal amount, having the same Original Issue
Date and Stated Maturity, and bearing a number not contemporaneously
outstanding.

         If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
Security, and (ii) such security or indemnity as may be required by them to save
each of them harmless, then, in the absence of notice to the Company or the
Trustee that such Security has been acquired by a bona fide purchaser, the
Company shall execute and upon its request the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of the same issue and series of like tenor and principal amount, having the same
Original Issue Date and Stated Maturity as such destroyed, lost or stolen
Security, and bearing a number not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.


                                       29
<PAGE>   36


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

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

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

         SECTION 3.7.    Payment of Interest; Interest Rights Preserved.

         Except as otherwise specified with respect to a series of Securities in
accordance with the provisions of Section 3.1, interest (including any
Additional Interest) on any Security of any series which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date, shall be
paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest in respect of Securities of such series, except that, unless
otherwise provided in the Securities of such series, interest payable on the
Stated Maturity of the principal of a Security shall be paid to the Person to
whom principal is paid. The initial payment of interest on any Security of any
series which is issued between a Regular Record Date and the related Interest
Payment Date shall be payable as provided in such Security or in the Board
Resolution pursuant to Section 3.1 with respect to the related series of
Securities. If a series of Securities is convertible into shares of common
stock, then, unless otherwise specified with respect to such Securities in
accordance with the provisions of Section 3.1, interest on such Interest Payment
Date shall be payable to each Holder on the related Regular Record Date
notwithstanding the conversion of any such Security between such Regular Record
Date and such Interest Payment Date.

         Any interest on any Security which is payable, but is not timely paid
or duly provided for (other than by reason of an extension of an interest
payment period), on any Interest Payment Date for Securities of such series
(herein called "Defaulted Interest"), shall forthwith cease to be payable to the
registered Holder on the relevant Regular Record Date by virtue of having

                                       30
<PAGE>   37

been such Holder, and such Defaulted Interest may be paid by the Company, at its
election in each case, as provided in Clause (1) or (2) below:

         (1) The Company may elect to make payment of any Defaulted Interest to
the Persons in whose names the Securities of such series in respect of which
interest is in default (or their respective Predecessor Securities) are
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest, which shall be fixed in the following manner. The
Company shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each Security and the date of the proposed payment, and
at the same time the Company shall deposit with the Trustee an amount of money
equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements satisfactory to the Trustee for such deposit
prior to the date of the proposed payment, such money when deposited to be held
in trust for the benefit of the Persons entitled to such Defaulted Interest as
in this Clause provided. Thereupon the Trustee shall fix a Special Record Date
for the payment of such Defaulted Interest which shall be not more than 15 days
and not less than 10 days prior to the date of the proposed payment and not less
than 10 days after the receipt by the Trustee of the notice of the proposed
payment. The Trustee shall promptly notify the Company of such Special Record
Date and, in the name and at the expense of the Company, shall cause notice of
the proposed payment of such Defaulted Interest and the Special Record Date
therefor to be mailed, first class, postage prepaid, to each Holder of a
Security of such series at the address of such Holder as it appears in the
Securities Register not less than 10 days prior to such Special Record Date. The
Trustee may, in its discretion, in the name and at the expense of the Company,
cause a similar notice to be published at least once in a newspaper, customarily
published in the English language on each Business Day and of general
circulation in the Borough of Manhattan, The City of New York, but such
publication shall not be a condition precedent to the establishment of such
Special Record Date. Notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor having been mailed as aforesaid, such
Defaulted Interest shall be paid to the Persons in whose names the Securities of
such series (or their respective Predecessor Securities) are registered on such
Special Record Date and shall no longer be payable pursuant to the following
Clause (2).

         (2) The Company may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities of the series in respect of which interest is in default
may be listed and, upon such notice as may be required by such exchange (or by
the Trustee if the Securities are not listed), if, after notice given by the
Company to the Trustee of the proposed payment pursuant to

                                       31
<PAGE>   38

this Clause, such payment shall be deemed practicable by the Trustee.

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

         SECTION 3.8. Persons Deemed Owners.

         The Company, the Trustee, any Authenticating Agent and any agent of the
Company or the Trustee may treat the Person in whose name any Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Section 3.7) any interest on
such Security and for all other purposes whatsoever, whether or not such
Security be overdue, and none of the Company, the Trustee, any Authenticating
Agent or any agent of the Company or the Trustee shall be affected by notice to
the contrary.

         No owner of a beneficial interest in any Global Security held on its
behalf by a Depository shall have any rights under this Indenture with respect
to such Global Security, and such Depository may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the owner and Holder of
such Global Security for all purposes whatsoever. None of the Company, the
Trustee, any Paying Agent or the Security Registrar will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests of a Global Security or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.

         SECTION 3.9. Cancellation.

         All Securities surrendered for payment, redemption, transfer or
exchange shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee, and any such Securities and Securities surrendered
directly to the Trustee for any such purpose shall be promptly canceled by it.
The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and all Securities so delivered
shall be promptly canceled by the Trustee. No Securities shall be authenticated
in lieu of or in exchange for any Securities canceled as provided in this
Section, except as expressly permitted by this Indenture. All canceled
Securities held by the Trustee shall be disposed of in accordance with its
customary practices, subject to applicable law.


                                       32
<PAGE>   39


         SECTION 3.10. Computation of Interest.

         Except as otherwise specified as contemplated by Section 3.1 for
Securities of any series, interest on the Securities of each series for any
period shall be computed on the basis of a 360- day year of twelve 30-day months
and, for any period less than a full calendar month, the number of days elapsed
in such month.

         SECTION 3.11.   Deferrals of Interest Payment Dates.

         If specified as contemplated by Section 2.1 or Section 3.1 with respect
to the Securities of a particular series, so long as no Event of Default has
occurred and is continuing, the Company shall have the right, at any time during
the term of such Securities, from time to time to defer the payment of interest
on such Securities for such period or periods as may be specified as
contemplated by Section 3.1 (each, an "Extension Period") during which Extension
Periods no interest shall be due and payable. At the end of any such Extension
Period, the Company shall pay all interest then accrued and unpaid on the
Securities (together with Additional Interest thereon, if any, at the rate
specified for the Securities of such series to the extent permitted by
applicable law); provided, however, that no Extension Period shall extend beyond
the Stated Maturity of the principal of the Securities of such series; provided,
further, that during any such Extension Period, the Company shall not, and shall
not permit any Subsidiary of the Company to, (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire, or make a liquidation payment
with respect to, any of the Company's capital stock (which includes common and
preferred stock) or (ii) make any payment of principal, interest or premium, if
any, on or repay or repurchase or redeem any debt securities of the Company
(including any Other Debentures) that rank pari passu in all respects with or
junior in interest to the Securities or (iii) make any guarantee payments with
respect to any guarantee by the Company of the debt securities of any Subsidiary
of the Company if such guarantee ranks pari passu with or junior in interest to
the Securities (other than (a) dividends or distributions in shares of, or
options, warrants or rights to subscribe for or purchase shares of, common stock
of the Company, (b) any declaration of a dividend in connection with the
implementation or extension of a stockholders' rights plan, or the issuance of
stock under any such plan in the future, or the redemption or repurchase of any
such rights pursuant thereto, (c) payments under the Guarantee with respect to
the Preferred Securities relating to such Securities and (d) as a result of a
reclassification of the Company's capital stock or the conversion or exchange of
one class or series of the Company's capital stock for another class or series
of the Company's capital stock; (e) the purchase of fractional interests in
shares of the Company's capital stock pursuant to the conversion or exchange
provisions of such capital stock or the security being converted or

                                       33
<PAGE>   40

exchanged; and (f) acquisitions of common stock of the Company in connection
with the satisfaction by the Company or any of its Subsidiaries of its
obligations under any benefit plan for its directors, officers or employees).
Before the termination of any such Extension Period, the Company may further
defer payments of interest by further extending such period, provided that no
Extension Period shall exceed the period or periods specified in such Securities
or extend beyond the Stated Maturity of the principal of such Securities. Upon
termination of any Extension Period and upon the payment of all accrued and
unpaid interest and any Additional Interest and additional amounts then due on
any Interest Payment Date, the Company may elect to begin a new Extension
Period, subject to the above requirements. No interest shall be due and payable
during an Extension Period, except at the end thereof. If the Property Trustee
of a Trust is the only registered holder of such Securities at the time the
Company elects an Extension Period, the Company shall give written notice to the
Administrative Trustees of such Trust, the Property Trustee of such Trust and
the Trustee of its election of such Extension Period (or an extension thereof)
at least five Business Days before the earlier of (i) the date on which
distributions on the Trust Securities issued by such Trust would have been
payable except for the election to begin or extend such Extension Period, or
(ii) the date the Administrative Trustees are required to give notice of the
record date, or the date such Distributions are payable, to any national
securities exchange or to holders of the Preferred Securities issued by the
Trust, but in any event at least five Business Days before such record date. If
the Property Trustee is not the only Holder of the Securities at the time the
Company elects an Extension Period, the Company shall give the Holders of the
Securities and the Trustee written notice of its election of such Extension
Period at least 10 Business Days before the earlier of (i) the next succeeding
Interest Payment Date, or (ii) the date the Company is required to give notice
of the record or payment date of such interest payment to any national
securities exchange. There is no limitation on the number of times that the
Company may elect to begin an Extension Period.

         SECTION 3.12.   Right of Set-Off.

         With respect to the Securities of a series issued to a Trust,
notwithstanding anything to the contrary in the Indenture, the Company shall
have the right to set-off any payment it is otherwise required to make
thereunder in respect of any such Security to the extent the Company has
theretofore made, or is concurrently on the date of such payment making, a
payment under the Guarantee relating to such Security or under Section 5.8 of
this Indenture.


                                       34
<PAGE>   41


         SECTION 3.13. Agreed Tax Treatment.

         Each Security issued hereunder shall provide that the Company and, by
its acceptance of a Security or a beneficial interest therein, the Holder of,
and any Person that acquires a beneficial interest in, such Security agree that
for United States Federal, State and local tax purposes it is intended that such
Security constitute indebtedness.

         SECTION 3.14. Shortening or Extension of Stated Maturity.

         If specified as contemplated by Section 2.1 or Section 3.1 with respect
to the Securities of a particular series, the Company shall have the right to
(i) shorten the Stated Maturity of the principal of the Securities of such
series at any time to any date not earlier than the first date on which the
Company has the right to redeem the Securities of such series, and (ii) extend
the Stated Maturity of the principal of the Securities of such series at any
time at its election for one or more periods, but in no event to a date later
than such date as shall be so specified with respect to the Securities of such
series. If the Company elects to exercise its right to shorten or extend the
Stated Maturity of Securities of a series, the Company shall give the Trustee
notice of such election within the time period specified as contemplated by
Section 3.1. The Company shall also give notice of the Company's election to the
Holders of the Outstanding Securities of such series in the manner and within
the time period as may be specified as contemplated by Section 3.1. If requested
by the Company, the Trustee, at the expense of the Company, shall give such
notice to the Holders of the Outstanding Securities of such series.

         Securities of a series whose Stated Maturity has been shortened or
extended that are authenticated and delivered after the shortening or extension
of the Stated Maturity of such Securities may, and shall if required by the
Company, bear a notation in such form as shall be approved by the Company as to
the change of such Stated Maturity. If the Company shall so determine, new
Securities of any series whose Stated Maturity has been changed, modified so as
to conform in the opinion of the Company to such change, may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.

         SECTION 3.15. CUSIP Numbers.

         The Company in issuing the Securities may use "CUSIP", "ISIN" and
"Common Code" numbers (if then generally in use), and, if so, the Trustee shall
use such numbers in notices of redemption as a convenience to Holders; provided
that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Securities

                                       35
<PAGE>   42

or as contained in any notice of a redemption and that reliance may be placed
only on the other identification numbers printed on the Securities, and any such
redemption shall not be affected by any defect in or omission of such numbers.


                                   ARTICLE IV

                           SATISFACTION AND DISCHARGE

         SECTION 4.1. Satisfaction and Discharge of Indenture.

         This Indenture shall, upon Company Request, cease to be of further
effect with respect to any series of Securities specified in such Company
Request (except as (i) otherwise may be specified with respect to such series of
Securities as contemplated by Section 3.1, (ii) to any right to receive payments
of the principal of, premium, if any, and interest (including any Additional
Interest) on the Securities of such series from the funds described below, and
(iii) otherwise provided in this Section 4.1), and the Trustee, on demand of and
at the expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture with respect to such series, when

         (1) either

         (a) all Securities of such series theretofore authenticated and
delivered (other than (i) Securities which have been destroyed, lost or stolen
and which have been replaced or paid as provided in Section 3.6 and (ii)
Securities for whose payment money has theretofore been deposited in trust by
the Company or segregated and held in trust and thereafter repaid to the Company
or discharged from such trust, as provided in Section 10.3) have been delivered
to the Trustee for cancellation; or

         (b) all such Securities of such series not theretofore delivered to the
Trustee for cancellation

         (i) have become due and payable, or

         (ii) will become due and payable at their Maturity within one year of
the date of deposit, or

         (iii) a are to be called for redemption within one year under
arrangements satisfactory to the Trustee for the giving of notice of redemption
by the Trustee in the name, and at the expense, of the Company, and the Company
has irrevocably deposited or caused to be deposited with the Trustee as trust
funds in trust for such purpose an amount in the currency or currencies in which
the

                                       36
<PAGE>   43

Securities of such series are payable sufficient to pay and discharge the entire
indebtedness on such Securities not theretofore delivered to the Trustee for
cancellation, for principal (and premium, if any) and interest (including any
Additional Interest) to the date of such deposit (in the case of Securities
which have become due and payable) or to the Maturity or Redemption Date
thereof, as the case may be;

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

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

         Notwithstanding the satisfaction and discharge of this Indenture with
respect to a series of Securities, the obligations with respect to the right of
registration of transfer or exchange of Securities of such series provided for
herein, the obligations with respect to any conversion or exchange of Securities
of such series provided pursuant to Section 3.1, the obligations of the Company
to the Trustee under Section 6.7, the obligations of the Trustee to any
Authenticating Agent under Section 6.14 and, if money shall have been
irrevocably deposited with the Trustee pursuant to paragraph (b) of subsection

last paragraph of Section 10.3 shall survive.

         SECTION 4.2. Application of Trust Money.

         (1) Subject to the provisions of the last paragraph of Section 10.3,
all money deposited with the Trustee pursuant to Section 4.1 shall be held in
trust and applied by the Trustee, in accordance with the provisions of the
Securities and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal,
premium, if any, and interest (including any Additional Interest) for whose
payment such money has been deposited with or received by the Trustee.

                                    REMEDIES

         SECTION 5.1. Events of Default.

         "Event of Default," wherever used herein with respect to Securities of
any series (unless otherwise specified with respect to such series of Securities
in accordance with Section 3.1),

                                       37
<PAGE>   44

means any one of the following events that has occurred and is continuing
(whatever the reason for such Event of Default and whether it shall be voluntary
or involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

         (1) default in the payment of any interest upon any Security of that
series when it becomes due and payable, and continuance of such default for a
period of 30 days; provided, however, that a valid extension of an interest
payment period by the Company in accordance with the terms hereof shall not
constitute a default in the payment of interest for this purpose; or

         (2) default in the payment of all or any part of the principal of (or
premium, if any, on) any Security of that series as and when the same shall
become due and payable either at maturity, upon redemption, by declaration of
acceleration of maturity or otherwise, or in any payment required by any sinking
or analogous fund established with respect to that series; provided that a valid
exchange of a Security upon its Maturity for another Security pursuant to this
Indenture or the supplemental indenture, Board Resolution or other instrument
authorizing Securities of that series shall not constitute a default in the
payment of the principal of the Security being exchanged for this purpose; or

         (3) if applicable to the Securities of that series, failure by the
Company to issue the property or other securities upon an election by the Holder
or Holders of such Securities to convert such Securities into property or other
securities, as the case may be, pursuant to the supplemental indenture, Board
Resolution or other instrument authorizing such series of Securities; or

         (4) default in the performance, or breach, in any material respect, of
any covenant or warranty of the Company in this Indenture (other than a covenant
or warranty 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 Company by the Trustee or to the Company and the Trustee by the Holders
of at least 25% in aggregate principal amount of the Outstanding Securities of
that series a written notice specifying such default or breach and requiring it
to be remedied and stating that such notice is a "Notice of Default" hereunder;
or

         (5) a court having jurisdiction in the premises shall have entered a
decree or order for relief in respect of the Company in an involuntary
proceeding under any applicable United States bankruptcy, insolvency,
reorganization or other similar law now


                                       38
<PAGE>   45

or hereafter in effect, or appointing a receiver, liquidator, assignee,
custodian, trustee, sequestrator (or other similar official) of the Company or
of all or 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

         (6) the Company shall have commenced a voluntary proceeding under any
applicable United States bankruptcy, insolvency, reorganization or other similar
law now or hereafter in effect, or shall have consented to the entry of an order
for relief in an involuntary case under any such law, or shall have consented to
the appointment of or taking possession by a receiver, liquidator, assignee,
trustee, custodian, sequestrator (or other similar official) of the Company or
of all or any substantial part of its property, or shall have made an assignment
for the benefit of creditors, or shall have failed generally to pay its debts as
they become due; or

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

         SECTION 5.2. Acceleration of Maturity; Rescission and Annulment.

         Unless otherwise provided as contemplated by Section 3.1 with respect
to any series of Securities, if an Event of Default (other than an Event of
Default specified in Section 5.1(5) or 5.1(6)) with respect to Securities of any
series at the time Outstanding occurs and is continuing, then and in every such
case the Trustee or the Holders of not less than 25% in aggregate principal
amount of the Outstanding Securities of that series may declare the principal
amount (or, if the Securities of that series are Discount Securities, such
portion of the principal amount as may be specified in the terms of that series)
of all the Securities of that series to be due and payable immediately, by a
notice in writing to the Company (and to the Trustee if given by Holders), and
upon such declaration the same shall become immediately due and payable. Payment
of principal and interest (including any Additional Interest) on such Securities
shall remain subordinated to the extent provided in Article XIII notwithstanding
that such amount shall become immediately due and payable as herein provided. If
an Event of Default specified in Section 5.1(5) or 5.1(6) with respect to
Securities of any series at the time Outstanding occurs, the principal amount of
all the Securities of that series (or, if the Securities of that series are
Discount Securities, such portion of the principal amount of such Securities as
may be specified by the terms of that series) shall automatically, and without
any declaration or other action on the part of the Trustee or any Holder, become
immediately due and payable.

                                       39
<PAGE>   46

         The foregoing provisions, however, are subject to the condition that,
if at any time after the principal of the Securities of a series 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,
(i) the Company shall pay or shall deposit with the Trustee a sum sufficient to
pay (A) all matured installments of interest upon all the Securities of that
series and the principal of and premium, if any, on any and all Securities of
that series which shall have become due otherwise than by acceleration (with
interest upon such principal and premium, if any, and, to the extent that
payment of such interest is enforceable under applicable law, on overdue
installments of interest, at the same rate as the rate of interest specified in
the Securities of that series to the date of such payment or deposit) and (B)
such amount as shall be sufficient to cover reasonable compensation to the
Trustee and each predecessor Trustee, 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 (ii) any and all Events of Default with respect to Securities of
that series under the Indenture shall have been cured, waived or otherwise
remedied as provided herein, then, in every such case, the Holders of a majority
in aggregate principal amount of the Securities of that series then Outstanding,
by written notice to the Company and to the Trustee, may 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.

         In case the Trustee shall have proceeded to enforce any right under
this Indenture and such proceedings shall have been discontinued or abandoned
because of such rescission or annulment or for any other reason or shall have
been determined adversely to the Trustee, then and in every such case the
Company, the Trustee and the Holders of the Securities of the applicable series
shall be restored respectively to their several positions and rights hereunder,
and all rights, remedies and powers of the Company, the Trustee and the Holders
of the Securities of that series shall continue as though no such proceeding had
been taken.

         SECTION 5.3. Collection of Indebtedness and Suits for Enforcement by
                      Trustee.

         The Company covenants that if:

         (1) default is made in the payment of any installment of interest
(including any Additional Interest) on any Security when such interest becomes
due and payable and such default continues for a period of 30 days, or

                                       40
<PAGE>   47

         (2) default is made in the payment of the principal of (and premium, if
any, on) any Security at the Maturity thereof, the Company will, upon demand of
the Trustee, pay to the Trustee, for the benefit of the Holders of such
Securities, the whole amount then due and payable on such Securities for
principal, including any sinking fund payment or analogous obligations (and
premium, if any) and interest, and, in addition thereto, all amounts owing the
Trustee under Section 6.7.

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

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

         SECTION 5.4. Trustee May File Proofs of Claim.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors,

         (1) the Trustee (irrespective of whether the principal of the
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 on the Company for the payment of overdue principal (and
premium, if any) or interest) shall be entitled and empowered, by intervention
in such proceeding or otherwise,

         (a) to file and prove a claim for the whole amount of principal (and
premium, if any) and interest (including any Additional Interest) owing and
unpaid in respect to the Securities and to file such other papers or documents
as may be necessary or advisable and to take any and all actions as are
authorized under the Trust Indenture Act in order to have the

                                       41
<PAGE>   48

claims of the Holders and any predecessor to the Trustee under Section 6.7
allowed in any such judicial proceedings; and

         (b) in particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same in accordance with Section 5.6; and

         (2) any custodian, receiver, assignee, trustee, liquidator,
sequestrator (or other similar official) in any such judicial proceeding is
hereby authorized by each Holder to make such payments to the Trustee for
distribution in accordance with Section 5.6, and in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to it and any predecessor Trustee under Section 6.7.

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

         SECTION 5.5. Trustee May Enforce Claim Without Possession of
                      Securities.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of all the amounts owing the Trustee and any
predecessor Trustee under Section 6.7, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

         SECTION 5.6. Application of Money Collected.

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


                                       42
<PAGE>   49


         FIRST: To the payment of all amounts due the Trustee and any
predecessor Trustee under Section 6.7;

         SECOND: To the payment of all Senior Indebtedness of the Company if and
to the extent required by Article XIII;

         THIRD: In case the principal of the outstanding Securities in respect
of which moneys have been collected shall not have become due and be unpaid, to
the payment of the amounts then due and unpaid upon Securities for principal of
(and premium, if any) and interest (including any Additional Interest) on the
Securities, in respect of which or for the benefit of which money has been
collected, ratably, without preference or priority of any kind, according to the
amounts due on such Securities for principal (and premium, if any) and interest,
respectively; and

         FOURTH: To the Company.

         SECTION 5.7. Limitation on Suits.

         Subject to Section 5.8, no Holder of any Securities of any series shall
have any right to institute any proceeding, judicial or otherwise, with respect
to this Indenture or for the appointment of a receiver, assignee, trustee,
liquidator, sequestrator (or other similar official) or for any other remedy
hereunder, unless:

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

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

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

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

         (5) no direction inconsistent with such written request has been given
to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Outstanding Securities of that series; it being
understood and intended that no one or more of such Holders shall have any right
in any manner whatever by virtue of, or by availing itself of, any provision of
this Indenture to

                                       43
<PAGE>   50

affect, disturb or prejudice the rights of any other Holders of Securities, or
to obtain or to seek to obtain priority or preference over any other of such
Holders or to enforce any right under this Indenture, except in the manner
herein provided and for the equal and ratable benefit of all such Holders.

         SECTION 5.8. Unconditional Right of Holders to Receive Principal,
                      Premium and Interest; Direct Action by Holders of
                      Preferred Securities.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right which is absolute and unconditional to receive
payment of the principal of (and premium, if any) and (subject to Section 3.7)
interest on such Security on the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such right shall not
be impaired without the consent of such Holder. In the case of Securities of a
series issued to a Trust, any holder of the corresponding series of Preferred
Securities issued by such Trust shall have the right, upon the occurrence of an
Event of Default described in Section 5.1(1) or 5.1(2), to institute a suit
directly against the Company for enforcement of payment to such holder of
principal of (premium, if any) and (subject to Section 3.7) interest on the
Securities having a principal amount equal to the aggregate Liquidation Amount
(as defined in the Declaration of Trust under which such Trust is formed) of
such Preferred Securities of the corresponding series held by such holder.

         SECTION 5.9. Restoration of Rights and Remedies.

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

         SECTION 5.10. Rights and Remedies Cumulative.

         Except as otherwise provided in the last paragraph of Section 3.6, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to


                                       44
<PAGE>   51

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.

         SECTION 5.11. Delay or Omission Not Waiver.

         No delay or omission of the Trustee, any Holder of any Security or any
holder of any Preferred Security to exercise any right or remedy accruing upon
any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein.

         Every right and remedy given by this Article or by law to the Trustee
or to the Holders and the right and remedy given to the holders of Preferred
Securities by Section 5.8 may be exercised from time to time, and as often as
may be deemed expedient, by the Trustee, the Holders or the holders of Preferred
Securities, as the case may be.

         SECTION 5.12. Control by Holders.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee, with respect to the
Securities of such series, provided that:

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

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

         (3) subject to the provisions of Section 6.1, the Trustee shall have
the right to decline to follow such direction if a Responsible Officer or
Officers of the Trustee shall, in good faith, determine that the proceeding so
directed would be unjustly prejudicial to the Holders not joining in any such
direction or would involve the Trustee in personal liability.

         SECTION 5.13. Waiver of Past Defaults.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series may waive any past default hereunder and its
consequences with respect to such series except a default:

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


                                       45
<PAGE>   52

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

         Any such waiver shall be deemed to be on behalf of the Holders of all
the Securities of such series.

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

         SECTION 5.14. Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant (other
than the Company and the Trustee) in such suit of an undertaking to pay the
costs of such suit, and that such court may in its discretion assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses
made by such party litigant; but the provisions of this Section shall not apply
to any suit instituted by the Company, to any suit instituted by the Trustee, to
any suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of the Outstanding Securities of any series,
to any suit instituted by any Holder for the enforcement of the payment of the
principal of or any premium or interest (including any Additional Interest) on
any Security on or after the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on or after the Redemption Date), or to
any suit instituted by any Holder for the enforcement of any right to convert or
exchange such Security into or for property or other securities.

         SECTION 5.15. Waiver of Usury, Stay or Extension Laws.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any usury, stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted


                                       46
<PAGE>   53

to the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.


                                   ARTICLE VI

                                   THE TRUSTEE

         SECTION 6.1. Certain Duties and Responsibilities.

         (1) Except during the continuance of an Event of Default,

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

         (b) in the absence of bad faith on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture; but in the case of
any such certificates or opinions which by any provisions 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.

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

         (3) 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) this Subsection shall not be construed to limit the effect of
Subsection (1) of this Section;

         (b) the Trustee shall not be liable for any error of judgment made in
good faith by a Responsible Officer, unless it shall be proved that the Trustee
was negligent in ascertaining 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
Holders pursuant to Section 5.12 relating to the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising


                                       47
<PAGE>   54

any trust or power conferred upon the Trustee, under this Indenture with respect
to the Securities of such series.

         (4) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if there shall be reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

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

         SECTION 6.2. Notice of Defaults.

         Within 90 days after actual knowledge by a Responsible Officer of the
Trustee of the occurrence of any default hereunder with respect to the
Securities of any series, the Trustee shall transmit by mail to all Holders of
Securities of such series, as their names and addresses appear in the Securities
Register, notice of such default, unless such default shall have been cured or
waived; provided, however, that, except in the case of a default in the payment
of the principal of (or premium, if any) or interest on any Security 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 and/or Responsible Officers of the Trustee in good faith determines
that the withholding of such notice is in the interests of the Holders of
Securities of such series; and provided, further, that, in the case of any
default of the character specified in Section 5.1(3), no such notice to Holders
of Securities of such series shall be given until at least 30 days after the
occurrence thereof. For the purpose of this Section, the term "default" means
any event which is, or after notice or lapse of time or both would become, an
Event of Default with respect to Securities of such series.

         SECTION 6.3. Certain Rights of Trustee.

         Subject to the provisions of Section 6.1:

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


                                       48
<PAGE>   55

         (2) any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order (other than
delivery of any Security to the Trustee for authentication and delivery pursuant
to Section 3.3 which shall be sufficiently evidenced as provided therein) and
any resolution of the Board of Directors may be sufficiently evidenced by a
Board Resolution;

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

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

Company or any Holder.

         SECTION 6.4. Not Responsible for Recitals or Issuance of Securities.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and neither the Trustee nor any Authenticating Agent assumes any
responsibility for their correctness. Neither the Trustee nor any Authenticating
Agent makes any representation as to the validity or sufficiency of this
Indenture or of the Securities, except that the Trustee, and any Authenticating
Agent, represents that it is duly authorized to execute and deliver this
Indenture, authenticate the Securities and perform its obligations hereunder and
that any statements made by it in a Statement of Eligibility on Form T-1

         SECTION 6.7. Compensation and Reimbursement.

         The Company agrees

         (1) to pay to the Trustee such compensation as shall be agreed upon in

                                       50
<PAGE>   57

expenses, disbursements and advances incurred or made by the Trustee in
accordance with any provision of this Indenture (including the reasonable
compensation and the expenses and disbursements of its agents and counsel and
other persons not regularly in its employ), except any such expense,
disbursement or advance as may be attributable to its gross negligence or bad

         (3) to indemnify the Trustee and its officers, directors, employees and
agents for, and to hold each of them harmless against, any and all loss,
liability, damage or expense, including taxes (other than taxes based upon the

surplus of at least $50,000,000, subject to supervision or examination by United
States Federal or State authority. 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

resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

         (4) If at any time:

         (a) the Trustee shall fail to comply with Section 6.8 after written

Board Resolution, may remove the Trustee with respect to all Securities, or (ii)
subject to Section 5.14, any Holder who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal

Trustee or Trustees.

         (5) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee with respect to the
Securities of that or those series. If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee
with respect to the Securities of any series shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities of such
series delivered to the Company and the retiring Trustee, the successor Trustee
so appointed shall, forthwith upon its acceptance of such appointment, become
the successor Trustee with respect to the Securities of such series and
supersede the successor Trustee appointed by the Company. If no successor
Trustee with respect to the Securities of any series shall have been so
appointed by the Company or the Holders and accepted appointment in the manner
hereinafter provided, any Holder who has been a bona fide Holder of a Security
for at least six months may, subject to Section 5.14, on behalf of himself and

Securities of any series by mailing written notice of such event by first-class
mail, postage prepaid, to the Holders of Securities of such series as their

and the address of its Corporate Trust Office.

         SECTION 6.11. Acceptance of Appointment by Successor.

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

         (2) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (i) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (ii)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(iii) 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


                                       54
<PAGE>   61

indenture shall constitute such Trustees co-trustees of the same trust and that
each such Trustee shall be trustee of a trust or trusts hereunder separate and
apart from any trust or trusts hereunder administered by any other such Trustee;
and upon the execution and delivery of such supplemental indenture the
resignation or removal of the retiring Trustee shall become effective to the
extent provided therein and each such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers,
trusts, and duties of the retiring Trustee with respect to the Securities of
that or those series to which the appointment of such successor Trustee relates;
but, on request of the Company or any successor Trustee, such retiring Trustee
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder with respect to the Securities
of that or those series to which the appointment of such successor Trustee
relates.

         (3) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all rights, powers and trusts referred to
in paragraph (1) or (2) of this Section, as the case may be.

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

         SECTION 6.12.    Merger, Conversion, Consolidation or Succession to
                          Business.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated, and in case any
Securities shall not have been authenticated, any successor to the Trustee may
authenticate such Securities either in the name of any predecessor Trustee or in
the name of such successor Trustee, and in all cases the certificate of
authentication shall have the full force which it is provided anywhere in the
Securities or in this Indenture that the certificate of the Trustee shall have.

         SECTION 6.13. Preferential Collection of Claims Against Company.

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

         SECTION 6.14. Appointment of Authenticating Agent.

         The Trustee may appoint an Authenticating Agent or Agents with respect
to one or more series of Securities which shall be authorized to act on behalf
of the Trustee to authenticate Securities of such series issued upon original
issue and upon exchange, registration of transfer or partial redemption thereof
or pursuant to Section 3.6, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States, or of any State or Territory or the
District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject
to supervision or examination by United States Federal or State authority. If
such Authenticating Agent publishes reports of condition at least annually,
pursuant to law or to the requirements of said supervising or examining
authority, then for the purposes of this Section the combined capital and
surplus of such Authenticating Agent shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published. If
at any time an Authenticating Agent shall cease to be eligible in accordance
with the provisions of this Section, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of an Authenticating Agent shall be the successor
Authenticating Agent hereunder, provided such corporation shall be otherwise
eligible under this Section, without the execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent.

                                       56
<PAGE>   63


         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 1.6 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provision of this Section.

         The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 6.7.

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

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

Dated:

         (3) to convey, transfer, assign, mortgage or pledge any property to or
with the Trustee or to surrender any right or power herein conferred upon the
Company; or

         (4) to add to, change or eliminate the covenants of the Company for the
benefit of the Holders of all or any series of Securities (and if such covenants
are to be for the benefit of less than all series of Securities, stating that
such covenants are expressly being included solely for the benefit of such
series) or to change or eliminate any of the other provisions of this Indenture,
provided that any such addition, change or elimination not otherwise permitted
under this Section 9.1 shall (i) become effective only when there is no Security
Outstanding of any series created prior to the execution of such supplemental
indenture which is entitled to the benefit of such provision or (ii) not apply
to any Security then Outstanding, or to surrender any right or power herein
conferred upon the Company; or

         (5) to add any additional Events of Default for the benefit of the
Holders of all or any series of Securities (and if such additional Events of
Default are to be for the benefit of less

                                       61
<PAGE>   68

than all series of Securities, stating that such additional Events of Default

         (6) to cure any ambiguity, to correct or supplement any provision
herein which may be defective or inconsistent with any other provision herein,
or to make any other provisions with respect to matters or questions arising
under this Indenture, provided that such action pursuant to this clause (6)
shall not adversely affect the interest of the Holders of Securities of any
series in any material respect; or

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

         (8) to comply with the requirements of the Commission in order to
effect or maintain the qualification of this Indenture under the Trust Indenture
Act; or

         (9) to add to, delete from or revise the conditions, limitations and
restrictions on the authorized amount, terms or purposes of issue,
authentication and delivery of Securities, as herein set forth; or

         (10) to make provision with respect to the conversion or exchange
rights of the Holders of any series of Securities pursuant to the requirements
of the supplemental indenture, Board Resolution, or other instrument
establishing the terms of such series of Securities; or

         (11) subject to Section 9.2(4), to make any change in Article Thirteen
that would limit or terminate the benefits available to any holder of Senior
Indebtedness under such Article;

provided, however, that so long as any Preferred Securities to which a series of
Securities relates remain outstanding, no such modification may be made pursuant
to this Section 9.1 that adversely affects the holders of such Preferred
Securities in any material respect.

         No consent of the holders of any Preferred Securities shall be required
in connection with any supplemental indenture entered into pursuant to this
Section 9.1.

         With the consent of the Holders of a majority in principal amount of
the Outstanding Securities of each series affected by such supplemental
indenture, by Act of said Holders delivered to the Company and the Trustee, the
Company, when authorized by a Board Resolution, and the Trustee may enter into
an indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or of modifying in any manner the rights of the Holders of
Securities of such series under this Indenture; provided, however, that no such
supplemental indenture shall, without the consent of the Holder of each
Outstanding Security affected thereby:

         (1) except to the extent permitted by Section 3.11 or Section 3.14 or
as otherwise specified as contemplated by Section 2.1 or Section 3.1 with
respect to the deferral of the payment of interest on the Securities of any
series or the shortening or extension of the Stated Maturity thereof, change the
Stated Maturity of the principal of, or any installment of interest on, any
Security, or reduce the principal amount thereof or the rate of interest thereon
or extend the time of payment of interest thereon or reduce any premium payable
upon the redemption thereof, or reduce the amount of principal of a Discount
Security that would be due and payable upon a declaration of acceleration of the
Maturity thereof pursuant to Section 5.2, or change the place of payment where,
or the coin or currency in which, any Security or interest (including any
Additional Interest) thereon is payable, or impair the right to institute suit
for the enforcement of any such payment on or after the Stated Maturity thereof
(or, in the case of redemption, on or after the Redemption Date), or

         (2) reduce the percentage in principal amount of the Outstanding
Securities of any series, the consent of whose Holders is required for any such

         (3) modify any of the provisions of this Section, Section 5.13 or
Section 10.5, except to increase any such percentage or to provide that certain
other provisions of this Indenture cannot be modified or waived without the
consent of the Holder of each Security affected thereby; or

         (4) to make provision with respect to the conversion or exchange rights
of the Holders of any series of Securities pursuant to the requirements of the
supplemental indenture, Board Resolution, or other instrument establishing the
terms of such series of Securities; or

                                       63
<PAGE>   70


         (5) modify the provisions in Article XIII of this Indenture with
respect to the subordination of Outstanding Securities of any series in a manner
adverse to the Holders thereof;

provided, further, that, in the case of the Securities of a series issued to a
Trust, so long as any of the corresponding series of Preferred Securities issued
by such Trust remains outstanding, (i) no such amendment shall be made that
adversely affects the holders of such Preferred Securities in any material
respect, without the prior consent of the holders of a majority of the aggregate
liquidation preference of such Preferred Securities then outstanding unless and
until the principal (and premium, if any) of the Securities of such series and
all accrued and, subject to Section 3.7, unpaid interest thereon have been paid
in full and (ii) no amendment shall be made to Section 5.8 of this Indenture
that would impair the rights of the holders of Preferred Securities provided
therein without the prior consent of the holders of each Preferred Security then
outstanding unless and until the principal (and premium, if any) of the
Securities of such series and all accrued and (subject to Section 3.7) unpaid
interest thereon have been paid in full.

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

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

         SECTION 9.3. Execution of Supplemental Indentures.

         In executing or accepting the additional trusts created by any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 6.1) shall be fully protected in relying upon, an
Officers' Certificate and an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture, and
that all conditions precedent have been complied with. The Trustee may, but
shall not be obligated to, enter into any such supplemental indenture which
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

         SECTION 9.4. Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental

of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

         SECTION 9.5. Conformity with Trust Indenture Act.

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

         SECTION 9.6. Reference in Securities to Supplemental Indentures.

         Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall if required by
the Company, bear a notation in form approved by the Company as to any matter
provided for in such supplemental indenture. If the Company shall so determine,
new Securities of any series so modified as to conform, in the opinion of the
Company, to any such supplemental indenture may be prepared and executed by the
Company and authenticated and delivered by the Trustee in exchange for
Outstanding Securities of such series.

                                    COVENANTS

         SECTION 10.1. Payment of Principal, Premium and Interest.

         The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and premium,
if any) and interest, including any Additional Interest (subject to (i) the
right of the Company to extend an interest payment period or, if so provided
pursuant to Section 3.1, to exchange a Security upon the Maturity of such
Security for another Security or to shorten or extend a Stated Maturity, and
(ii) the provisions of Section 3.12) on the Securities of that series in
accordance with the terms of such Securities and this Indenture.

         SECTION 10.2. Maintenance of Office or Agency.

         The Company shall maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where

                                       65
<PAGE>   72

Securities of that series may be surrendered for conversion or exchange or for
registration of transfer or exchange and where notices and demands to or upon
the Company in respect of the Securities of that series and this Indenture may
be served, and the Company hereby initially appoints the Trustee at its
Corporate Trust Office as its agent to receive all such presentations,
surrenders, notices and demands. The Company will give prompt written notice to
the Trustee of the location, and any change in the location, of each such office
or agency. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office.

         The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all of such purposes, and may from time to time
rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain
an office or agency in accordance with the requirements set forth above for
Securities of any series for such purposes. The Company shall give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency. Unless otherwise set
forth in, or pursuant to, a Board Resolution or any indenture supplemental
hereto with respect to a series of Securities, the Company hereby designates as
the Place of Payment for each series of Securities the Borough of Manhattan, The
City of New York, and initially appoints the Trustee at its Corporate Trust
Office as Paying Agent and as its agent to receive all such presentations,
surrenders, notices and demands.

         SECTION 10.3. Money for Security Payments to be Held in Trust.

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

         Whenever the Company shall have one or more Paying Agents, it will,
prior to 10:00 a.m. New York City time on each due date of the principal of or
interest on any Securities, deposit with a Paying Agent a sum sufficient to pay
the principal (and premium, if any) or interest so becoming due, such sum to be
held in trust for the benefit of the Persons entitled to such principal and


                                       66
<PAGE>   73

premium (if any) or interest, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its failure so to act.

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

         (1) hold all sums held by it for the payment of the principal of (and
premium, if any) or interest on Securities in trust for the benefit of the
Persons entitled thereto until such sums shall be paid to such Persons or
otherwise disposed of as herein provided;

         (2) give the Trustee notice of any default by the Company (or any other
obligor upon the Securities) in the making of any payment of principal (and
premium, if any) or interest;

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

         (4) comply with the provisions of the Trust Indenture Act applicable to
it as a Paying Agent.

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

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest on any Security and remaining unclaimed for two years after
such principal (and premium, if any) or interest has become due and payable
shall (unless otherwise required by mandatory provision of applicable escheat or
abandoned or unclaimed property law) be paid on Company Request to the Company,
or (if then held by the Company) shall (unless otherwise required by mandatory
provision of applicable escheat or abandoned or unclaimed property law) be
discharged from such trust; and the Holder of such Security shall thereafter, as
an unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent,

                                       67
<PAGE>   74

before being required to make any such repayment, may at the expense of the
Company cause to be published once, in a newspaper published in the English
language, customarily published on each Business Day and of general circulation
in the Borough of Manhattan, The City of New York, notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such publication, any unclaimed balance of
such money then remaining will be repaid to the Company.

         SECTION 10.4. Statement as to Compliance.

         The Company shall deliver to the Trustee, within 120 days after the end
of each calendar year of the Company ending after the date hereof, an Officers'
Certificate covering the preceding calendar year, stating whether or not to the
best knowledge of the signers thereof the Company is in default in the
performance, observance or fulfillment of or compliance with any of the terms,
provisions, covenants and conditions of this Indenture, and if the Company shall
be in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge. For the purpose of this Section 10.4, compliance
shall be determined without regard to any grace period or requirement of notice
provided pursuant to the terms of this Indenture.

         SECTION 10.5. Waiver of Certain Covenants.

         The Company may omit in any particular instance to comply with any
covenant or condition provided pursuant to Section 3.1, 9.1(3) or 9.1(4) with
respect to the Securities of any series, if before or after the time for such
compliance the Holders of a majority in principal amount of the Outstanding
Securities of such series shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company in respect of any such covenant
or condition shall remain in full force and effect.

         SECTION 10.6.      Additional Covenants.

         The Company covenants and agrees with each Holder of Securities of each
series that it shall not, and shall not permit any Subsidiary of the Company to,
(i) declare or pay any dividends or distributions on, or redeem, purchase,
acquire, or make a liquidation payment with respect to, any of the Company's
capital stock (which includes common and preferred stock) or (ii) make any
payment of principal, interest or premium, if any, on or repay or repurchase or
redeem any debt securities of the Company (including any Other Debentures) that
rank pari passu in all respects with or junior in interest to the Securities or
(iii)

                                       68
<PAGE>   75

make any guarantee payments with respect to any guarantee by the Company
of the debt securities of any Subsidiary of the Company if such guarantee ranks
pari passu with or junior in interest to the Securities (other than (a)
dividends or distributions in shares of, or options, warrants or rights to
subscribe for or purchase shares of, common stock of the Company, (b) any
declaration of a dividend in connection with the implementation or extension of
a stockholders' rights plan, or the issuance of stock under any such plan in the
future, or the redemption or repurchase of any such rights pursuant thereto, (c)
payments under the Guarantee with respect to the Preferred Securities relating
to such series of Securities and (d) as a result of a reclassification of the
Company's capital stock or the exchange or the conversion of one class or series
of the Company's capital stock for another class or series of the Company's
capital stock; (e) the purchase of fractional interests in shares of the
Company's capital stock pursuant to the conversion or exchange provisions of
such capital stock or the security being converted or exchanged; and (f)
acquisitions of common stock of the Company in connection with the satisfaction
by the Company or any of its Subsidiaries of its obligations under any benefit
plan for its directors, officers or employees), if at such time (i) there shall
have occurred and be continuing any event of which the Company has actual
knowledge (A) that is, or with the giving of notice or the lapse of time, or
both, would constitute an Event of Default with respect to the Securities of
such series and (B) in respect of which the Company shall not have taken
reasonable steps to cure, (ii) if the Securities of such series are held by a
Trust, the Company shall be in default with respect to its payment of any
obligations under the Guarantee relating to the Preferred Securities issued by
such Trust or (iii) the Company shall have given notice of its election to begin
an Extension Period with respect to the Securities of such series as provided
herein and shall not have rescinded such notice, and such Extension Period, or
any extension thereof, shall be continuing.

         The Company also covenants with each Holder of Securities of a series
issued to a Trust (i) to maintain directly or indirectly 100% ownership of the
Common Securities of such Trust; provided, however, that any permitted successor
of the Company hereunder may succeed to the Company's ownership of such Common
Securities, (ii) to use its reasonable efforts to cause such Trust (a) to remain
a business trust, except as permitted by the related Declaration of Trust, and
(b) to otherwise continue to be classified as a grantor trust and not an
association taxable as a corporation or a partnership for United States Federal
income tax purposes and (iii) to use its reasonable efforts to cause each holder
of Trust Securities to be treated as owning an individual beneficial interest in
the Securities of such Series.

Preferred Securities) related to each Trust.


                                   ARTICLE XI

                            REDEMPTION OF SECURITIES

         SECTION 11.1.     Applicability of This Article.

         Redemption of Securities of any series (whether by operation of a
sinking fund or otherwise) as permitted or required by any form of Security
issued pursuant to this Indenture shall be made in accordance with such form of
Security and this Article; provided, however, that if any provision of any such
form of Security shall conflict with any provision of this Article, the
provision of such form of Security shall govern. Except as otherwise set forth
in the form of Security for such series, each Security of such series shall be
subject to partial redemption only in the amount specified as contemplated in
Section 3.1.

                                       70
<PAGE>   77


         SECTION 11.2. Election to Redeem; Notice to Trustee.

         In case of any redemption at the election of the Company of less than
all of the Securities of any particular series and having the same terms, the
Company shall, not less than 30 nor more than 60 days prior to the Redemption
Date (unless a shorter notice shall be satisfactory to the Trustee), notify the
Trustee of such date and of the principal amount of Securities of that series to
be redeemed. In the case of any redemption of Securities prior to the expiration
of any restriction on such redemption provided in the terms of such Securities,
the Company shall furnish the Trustee with an Officers' Certificate and an
Opinion of Counsel evidencing compliance with such restriction.

         SECTION 11.3. Selection of Securities to be Redeemed.

         If less than all the Securities of any series are to be redeemed
(unless all the Securities of such series and of a specified tenor are to be
redeemed or unless such redemption affects only a single Security), the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of a portion of the principal amount of any Security of such series,
provided that the unredeemed portion of the principal amount of any Security
shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security. If less than all the Securities of
such series and of a specified tenor are to be redeemed (unless such redemption
affects only a single Security), the particular Securities to be redeemed shall
be selected not more than 60 days prior to the Redemption Date by the Trustee,
from the Outstanding Securities of such series and specified tenor not
previously called for redemption in accordance with the preceding sentence.

         The Trustee shall promptly notify the Company in writing of the
Securities selected for partial redemption and the principal amount thereof to
be redeemed. For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any 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. If the Company shall so direct, Securities registered in the name of
the Company, any Affiliate or any Subsidiary thereof shall not be included in
the Securities selected for redemption.

<PAGE>   78


         SECTION 11.4. Notice of Redemption.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not later than the thirtieth day, and not earlier than the
sixtieth day, prior to the Redemption Date, to each Holder of Securities to be
redeemed, at the address of such Holder as it appears in the Securities
Register.

         With respect to Securities of each series to be redeemed, each notice
of redemption shall state:

         (1) the Redemption Date;

         (2) the Redemption Price;

         (3) if less than all Outstanding Securities of such particular series
and having the same terms are to be redeemed, the identification (and, in the
case of partial redemption, the respective principal amounts) of the particular
Securities to be redeemed;

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

         (5) the place or places where such Securities are to be surrendered for
payment of the Redemption Price;

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

         (7) the CUSIP number (or any other numbers used by a Depository to
identify such Securities), if any, of the Securities to be redeemed; and

         (8) if the Securities of such series are convertible into or
exchangeable for another security at the option of the Holder, that a Holder of
such Series who desires to convert or exchange the Securities called for
redemption must satisfy the requirements for conversion or exchange contained in
such Securities, the then existing conversion or exchange price or rate, and the
date and time when the option to convert or exchange shall expire.

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall not be
irrevocable. The notice if mailed in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the Holder
receives such notice. In any case, a failure to give such notice by mail or any


                                       72
<PAGE>   79

defect in the notice to the Holder of any Security designated for redemption as
a whole or in part shall not affect the validity of the proceedings for the
redemption of any other Security.

         SECTION 11.5.     Deposit of Redemption Price.

         Prior to 10:00 a.m. New York City time on the Redemption Date specified
in the notice of redemption given as provided in Section 11.4, the Company will
deposit with the Trustee or with one or more Paying Agents (or if the Company is
acting as its own Paying Agent, the Company will segregate and hold in trust as
provided in Section 10.3) an amount of money sufficient to pay the Redemption
Price of, and any accrued interest (including any Additional Interest) on, all
the Securities which are to be redeemed on that date.

         SECTION 11.6.     Payment of Securities Called for Redemption.

         If any notice of redemption has been given as provided in Section 11.4,
the Securities or portion of Securities with respect to which such notice has
been given shall become due and payable on the date and at the place or places
stated in such notice at the applicable Redemption Price. On presentation and
surrender of such Securities at a Place of Payment in said notice specified, the
said Securities or the specified portions thereof shall be redeemed by the
Company at the applicable Redemption Price, together with accrued interest to
the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 3.1, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 3.7.

         Upon presentation of any Security redeemed in part only, the Company
shall execute and the Trustee shall authenticate and deliver to the Holder
thereof, at the expense of the Company, a new Security or Securities of the same
series, of authorized denominations, in aggregate principal amount equal to the
unredeemed portion of the Security so presented and having the same Original
Issue Date, Stated Maturity and terms. If a Global Security is so surrendered,
such new Security will also be a new Global Security.

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

                                   ARTICLE XII

                                  SINKING FUNDS

         SECTION 12.1. Applicability of Article.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 3.1 for such Securities.

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

         SECTION 12.2. Satisfaction of Sinking Fund Payments with Securities.

         In lieu of making all or any part of a mandatory sinking fund payment
with respect to any Securities of a series in cash, the Company may at its
option, at any time no more than 16 months and no less than 30 days prior to the
date on which such sinking fund payment is due, deliver to the Trustee
Securities of such series theretofore purchased or otherwise acquired by the
Company, except Securities of such series that have been redeemed through the
application of mandatory or optional sinking fund payments pursuant to the terms
of the Securities of such series, accompanied by a Company Order instructing the
Trustee to credit such obligations and stating that the Securities of such
series were originally issued by the Company by way of bona fide sale or other
negotiation for value; provided that the Securities to be so credited have not
been previously so credited. The Securities to be so credited shall be received
and credited for such purpose by the Trustee at the redemption price for such
Securities, as specified in the Securities so to be redeemed, for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly.

         SECTION 12.3. Redemption of Securities for Sinking Fund.

         Not less than 30 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
such Securities pursuant to

                                       74
<PAGE>   81

the terms of such Securities, the portion thereof, if any, which is to be
satisfied by payment of cash in the currency in which the Securities of such
series are payable (except as provided pursuant to Section 3.1) and the portion
thereof, if any, which is to be satisfied by delivering and crediting Securities
pursuant to Section 12.2 and will also deliver to the Trustee any Securities to
be so delivered. Such Officers' Certificate shall be irrevocable and upon its
delivery the Company shall be obligated to make the cash payment or payments
therein referred to, if any, on or before the succeeding sinking fund payment
date. In the case of the failure of the Company to deliver such Officers'
Certificate (or, as required by this Indenture, the Securities and coupons, if
any, specified in such Officers' Certificate), the sinking fund payment due on
the succeeding sinking fund payment date for such series shall be paid entirely
in cash and shall be sufficient to redeem the principal amount of the Securities
of such series subject to a mandatory sinking fund payment without the right to
deliver or credit securities as provided in Section 12.2 and without the right
to make the optional sinking fund payment with respect to such series at such
time.

         Any sinking fund payment or payments (mandatory or optional) made in
cash plus any unused balance of any preceding sinking fund payments made with
respect to the Securities of any particular series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent) on
the sinking fund payment date on which such payment is made (or, if such payment
is made before a sinking fund payment date, on the sinking fund payment date
immediately following the date of such payment) to the redemption of Securities
of such series at the Redemption Price specified in such Securities with respect
to the sinking fund. Any sinking fund moneys not so applied or allocated by the
Trustee (or, if the Company is acting as its own Paying Agent, segregated and
held in trust by the Company as provided in Section 10.3) for such series and
together with such payment (or such amount so segregated) shall be applied in
accordance with the provisions of this Section 12.3. Any and all sinking fund
moneys with respect to the Securities of any particular series held by the
Trustee (or if the Company is acting as its own Paying Agent, segregated and
held in trust as provided in Section 10.3) on the last sinking fund payment date
with respect to Securities of such series and not held for the payment or
redemption of particular Securities of such series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent),
together with other moneys, if necessary, to be deposited (or segregated)
sufficient for the purpose, to the payment of the principal of the Securities of
such series at Maturity. The Trustee shall select the Securities to be redeemed
upon such sinking fund payment date in the manner specified in Section 11.3 and
cause notice of the redemption thereof to be given in the name of and at the
expense of the

                                       75
<PAGE>   82

Company in the manner provided in Section 11.4. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Section 11.6. On or before each sinking fund payment date, the
Company shall pay to the Trustee (or, if the Company is acting as its own Paying
Agent, the Company shall segregate and hold in trust as provided in Section
10.3) in cash a sum in the currency in which Securities of such series are
payable (except as provided pursuant to Section 3.1) equal to the principal and
any interest accrued to the Redemption Date for Securities or portions thereof
to be redeemed on such sinking fund payment date pursuant to this Section 12.3.

         Neither the Trustee nor the Company shall redeem any Securities of a
series with sinking fund moneys or mail any notice of redemption of Securities
of such series by operation of the sinking fund for such series during the
continuance of a default in payment of interest, if any, on any Securities of
such series or of any Event of Default (other than an Event of Default occurring
as a consequence of this paragraph) with respect to the Securities of such
series, except that if the notice of redemption shall have been provided in
accordance with the provisions hereof, the Trustee (or the Company, if the
Company is then acting as its own Paying Agent) shall redeem such Securities if
cash sufficient for that purpose shall be deposited with the Trustee (or
segregated by the Company) for that purpose in accordance with the terms of this
Article XII. 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 such sinking fund shall, during the continuance of such
default or Event of Default, be held as security for the payment of the
Securities and coupons, if any, of such series; provided, however, that in case
such default or Event of Default shall have been cured or waived herein, such
moneys shall thereafter be applied on the next sinking fund payment date for the
Securities of such series on which such moneys may be applied pursuant to the
provisions of this Section 12.3.

                                  ARTICLE XIII

                           SUBORDINATION OF SECURITIES

         SECTION 13.1. Securities Subordinate to Senior Indebtedness.

         The Company covenants and agrees, and each Holder of a Security, by its
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article, the payment of the principal
of, premium, if any, and interest (including any Additional Interest) on each

                                       76
<PAGE>   83

and all of the Securities is hereby expressly made subordinate and subject in
right of payment to the prior payment in full in cash of all Senior
Indebtedness.

         SECTION 13.2. Payment of Proceeds Upon Dissolution, Etc.

         Upon any payment or distribution of assets of the Company to creditors
upon any liquidation, dissolution, winding-up, reorganization, assignment for
the benefit of creditors, marshalling of assets or liabilities or any
bankruptcy, insolvency or similar proceedings of the Company (each such event,
if any, herein sometimes referred to as a "Proceeding"):

         (1) the holders of Senior Indebtedness shall be entitled to receive
payment in full in cash of all amounts due on or to become due on or in respect
of all Senior Indebtedness (including any interest accruing thereon after the
commencement of any such Proceeding, whether or not allowed as a claim against
the Company in such Proceeding) before the Holders of the Securities are
entitled to receive any payment or distribution (excluding any payment described
in the last paragraph of this Section 13.2 or any payment described in Section
13.9), on account of the principal of, premium, if any, or interest (including
any Additional Interest) on the Securities or on account of any purchase,
redemption or other acquisition of Securities by the Company or any Subsidiary
of the Company (all such payments, distributions, purchases, redemptions and
acquisitions, whether or not in connection with a Proceeding, herein referred
to, individually and collectively, as a "Securities Payment"); and

         (2) any payment or distribution of assets of the Company of any kind or
character, whether in cash, property or securities, by set-off or otherwise, to
which the Holders of the Securities or the Trustee would be entitled but for the
provisions of this Article shall be paid 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 or the Designated Senior Holders, ratably
according to the aggregate amounts remaining unpaid on account of the Senior
Indebtedness held or represented by each, to the extent necessary to make
payment in full in cash of all Senior Indebtedness remaining unpaid, after
giving effect to any concurrent payment or distribution to the holders of such
Senior Indebtedness.

         In the event that, notwithstanding the foregoing provisions of this
Section, the Trustee or the Holder of any Security shall have received in
connection with any Proceeding any Securities Payment before all Senior
Indebtedness is paid in full or payment thereof is provided for in cash, then
and in such event such Securities Payment shall be paid over or delivered
forthwith to the trustee in bankruptcy, receiver, liquidating trustee,

                                       77
<PAGE>   84

custodian, assignee, agent or other Person making payment or distribution of
assets of the Company for application to the payment of all Senior Indebtedness
remaining unpaid, to the extent necessary to pay all Senior Indebtedness in full
in cash after giving effect to any concurrent payment to or for the holders of
Senior Indebtedness.

         For purposes of this Article only, the words "payment or distribution"
or "any payment or distribution of any kind or character, whether in cash,
property or securities" shall not be deemed to include a payment or distribution
of stock or securities of the Company provided for by a plan of reorganization
or readjustment authorized by an order or decree of a court of competent
jurisdiction in a reorganization proceeding under any applicable bankruptcy law
or of any other corporation provided for by such plan of reorganization or
readjustment, which stock or securities are subordinated in right of payment to
all then outstanding Senior Indebtedness to substantially the same extent, or to
a greater extent than, the Securities are so subordinated as provided in this
Article. The consolidation of the Company with, or the merger of the Company
into, another Person or the liquidation or dissolution of the Company following
the conveyance, transfer or lease of all or substantially all of its properties
and assets to another Person upon the terms and conditions set forth in Article
VIII shall not be deemed a Proceeding for the purposes of this Section if the
Person formed by such consolidation or into which the Company is merged or the
Person which acquires by conveyance, transfer or lease such properties and
assets, as the case may be, shall, as a part of such consolidation, merger,
conveyance, transfer or lease, comply with the conditions set forth in Article
VIII.

         SECTION 13.3. No Payment When Senior Indebtedness in Default.

         In the event that any Senior Payment Default (as defined below) shall
have occurred and be continuing, then no Securities Payment shall be made,
unless and until such Senior Payment Default shall have been cured or waived in
writing or shall have ceased to exist or all amounts then due and payable in
respect of such Senior Indebtedness (including, without limitation, amounts that
have become and remain due by acceleration) shall have been paid in full in
cash. "Senior Payment Default" means any default in the payment of the principal
of, premium, if any, or interest on any Senior Indebtedness when due, whether at
the stated maturity of any such payment or by declaration of acceleration, call
for redemption, notice of the exercise of an option to require such repayment,
mandatory payment or prepayment or otherwise.

         In the event that any Senior Nonmonetary Default (as defined below)
shall have occurred and be continuing, then, upon the

                                       78
<PAGE>   85

receipt by the Company or the Trustee of written notice of such Senior
Nonmonetary Default from any holder or the Designated Senior Holder of the
Senior Indebtedness to which such Senior Nonmonetary Default relates, no
Securities Payment shall be made during the period (the "Payment Blockage
Period") commencing on the date of such receipt by the Company or the Trustee of
such written notice and ending on the earlier of (i) the date, if any, on which
the Senior Indebtedness to which such Senior Nonmonetary Default relates is
discharged or such Senior Nonmonetary Default shall have been cured or waived in
writing or shall have ceased to exist and any acceleration of Senior
Indebtedness to which such Senior Nonmonetary Default relates shall have been
rescinded or annulled and (ii) the 179th day after the date of such receipt of
such written notice. No more than one Payment Blockage Period may be commenced
with respect to the Securities during any period of 360 consecutive days and
there shall be a period of at least 181 consecutive days in each period of 360
consecutive days when no Payment Blockage Period is in effect. Following the
commencement of any Payment Blockage Period, the holders of Senior Indebtedness
shall be precluded from commencing a subsequent Payment Blockage Period until
the conditions set forth in the preceding sentence shall have been satisfied.
For all purposes of this paragraph, no Senior Nonmonetary Default that existed
or was continuing on the date of commencement of any Payment Blockage Period
with respect to the Senior Indebtedness initiating such Payment Blockage Period
shall be, or may be made, the basis for the commencement of a subsequent Payment
Blockage Period by any holder of Senior Indebtedness or a Designated Senior
Holder unless such Senior Nonmonetary Default shall have been cured for a period
of not less than 90 consecutive days. "Senior Nonmonetary Default" means any
default (other than a Senior Payment Default) or any event (other than a Senior
Payment Default) which, after notice or lapse of time (or both), would become an
event of default, under the terms of any instrument or agreement pursuant to
which any Senior Indebtedness is outstanding, permitting one or more holders of
such Senior Indebtedness or a Designated Senior Holder to declare such Senior
Indebtedness due and payable prior to the date on which it would otherwise
become due and payable.

         In the event that, notwithstanding the foregoing, the Company shall
make any Securities Payment to the Trustee or any Holder prohibited by the
foregoing provisions of this Section, then in such event such Securities Payment
shall be held in trust and paid over and delivered forthwith to the Designated
Senior Holders under the Senior Indebtedness or, if there is no Designated
Senior Holder with respect to such Senior Indebtedness, to the holders of such
Senior Indebtedness.

         The provisions of this Section shall not apply to any Securities
Payment with respect to which Section 13.2 hereof would be applicable.

                                       79
<PAGE>   86

         SECTION 13.4. Payment Permitted If No Default.

         Nothing contained in this Article or elsewhere in this Indenture or in
any of the Securities shall prevent the Company, at any time except during the
pendency of any Proceeding referred to in Section 13.2 hereof or under the
conditions described in Section 13.3 hereof, from making Securities Payments.
Nothing in this Article shall have any effect on the right of the Holders or the
Trustee to accelerate the maturity of the Securities upon the occurrence of an
Event of Default, but, in that event, no payment may be made in violation of the
provisions of this Article with respect to the Securities. If payment of the
Securities is accelerated because of an Event of Default, the Company shall
promptly notify the holders of the Senior Indebtedness (or their
representatives) of such acceleration.

         SECTION 13.5. Subrogation To Rights of Holders of Senior Indebtedness.

         Subject to the payment in full in cash of all Senior Indebtedness, the
Holders of the Securities shall be subrogated to the rights of the holders of
such Senior Indebtedness to receive payments and distributions of cash, property
and securities applicable to the Senior Indebtedness until the principal of,
premium, if any, and interest (including Additional Interest) on the Securities
shall be paid in full. For purposes of such subrogation, no payments or
distributions to the holders of the Senior Indebtedness of any cash, property or
securities to which the Holders of the Securities or the Trustee would be
entitled except for the provisions of this Article, and no payments pursuant to
the provisions of this Article to the holders of Senior Indebtedness by Holders
of the Securities or the Trustee, shall, as among the Company, its creditors
other than holders of Senior Indebtedness and the Holders of the Securities, be
deemed to be a payment or distribution by the Company to or on account of the
Senior Indebtedness.

         SECTION 13.6. Provisions Solely To Define Relative Rights.

         The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the Holders on the one hand and the
holders of Senior Indebtedness on the other hand. Nothing contained in this
Article or elsewhere in this Indenture or in the Securities is intended to or
shall (a) impair, as among the Company, its creditors other than holders of
Senior Indebtedness and the Holders of the Securities, the obligation of the
Company, which is absolute and unconditional (and which, subject to the rights
under this Article of the holders of Senior Indebtedness, is intended to rank
equally with all other general obligations of the Company), to pay to the
Holders of the Securities the principal of, premium, if any, and interest
(including Additional Interest) on the Securities as and


                                       80
<PAGE>   87

when the same shall become due and payable in accordance with their terms; or
(b) affect the relative rights against the Company of the Holders of the
Securities and creditors of the Company other than the holders of Senior
Indebtedness; or (c) prevent the Trustee or the Holder of any Security 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 to receive cash, property and securities otherwise
payable or deliverable to the Trustee or such Holder or, under the conditions
specified in Section 13.3, to prevent any payment prohibited by such Section or
enforce their rights pursuant to the penultimate paragraph in Section 13.3.

         SECTION 13.7. Trustee To Effectuate Subordination

         Each Holder of a Security by his acceptance thereof authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article and
appoints the Trustee his attorney-in-fact for any and all such purposes,
including, in the event of any dissolution, winding-up, liquidation or
reorganization of the Company, whether in bankruptcy, insolvency, receivership
proceedings, or otherwise, the timely filing of a claim for the unpaid balance
of the indebtedness of the Company owing to such Holder in the form required in
such proceedings and the causing of such claim to be approved. If the Trustee
does not file a proper claim at least 30 days before the expiration of the time
to file such claim, then the holders of the Senior Indebtedness and their
agents, trustees or other representatives are authorized to do so (but shall in
no event be liable for any failure to do so,) for and on behalf of the Holders
of the Securities.

         SECTION 13.8. No Waiver of Subordination Provisions.

         No right of any present or future holder of any Senior Indebtedness to
enforce the subordination provisions provided herein shall at any time in any
way be prejudiced or impaired by any act or failure to act on the part of the
Company or by any act or failure to act, in good faith, by any such holder, or
by any noncompliance by the Company with the terms, provisions and covenants of
this Indenture, regardless of any knowledge thereof any such holder may have or
be otherwise charged with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness may, at any time and from time to time,
without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article or
the obligations hereunder of the Holders of the Securities to

                                       81
<PAGE>   88

the holders of Senior Indebtedness, do any one or more of the following: (i)
change the manner, place or terms of payment or extend the time of payment of,
or renew or alter, Senior Indebtedness, or otherwise amend or supplement in any
manner Senior Indebtedness or any instrument evidencing the same or any
agreement under which Senior Indebtedness is outstanding; (ii) permit the
Company to borrow, repay and then reborrow any or all of the Senior
Indebtedness; (iii) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior Indebtedness; (iv) release any
Person liable in any manner for the collection of Senior Indebtedness; (v)
exercise or refrain from exercising any rights against the Company and any other
Person; and (vi) apply any sums received by them to Senior Indebtedness.

         SECTION 13.9. Trust Moneys Not Subordinated.

         Notwithstanding anything contained herein to the contrary, payments
from money held in trust by the Trustee under Article Four for the payment of
the principal of, premium, if any, and interest (including any Additional
Interest) on any series of Securities shall not be subordinated to the prior
payment of any Senior Indebtedness or subject to the restrictions set forth in
this Article, and no Holder of such Securities nor the Trustee shall be
obligated to pay over any such amount to the Company, any holder of Senior
Indebtedness, any Designated Senior Holder or any other creditor of the Company.

         SECTION 13.10. Notice to Trustee.

         The Company shall give prompt written notice to the Trustee of any fact
known to the Company that would prohibit the making of any payment to or by the
Trustee in respect of the Securities or that would end such prohibition.
Notwithstanding the provisions of this Article or any other provision of this
Indenture, the Trustee shall not be charged with knowledge of the existence of
any facts that would prohibit the making of any payment to or by the Trustee in
respect of the Securities or that would end such prohibition, unless and until
the Trustee shall have received written notice thereof from the Company, any
holder of Senior Indebtedness or any Designated Senior Holder; and, prior to the
receipt of any such written notice, the Trustee, subject to the provisions of
Section 6.1 hereof, shall be entitled in all respects to assume that no such
facts exist; provided, however, that, if prior to the close of business on the
second Business Day immediately preceding the date upon which by the terms
hereof any monies become payable hereunder (including, without limitation, the
payment of either the principal of, premium, if any, or interest on a Security),
the Trustee or any Paying Agent shall not have received with respect to such
monies the notice provided for in this Section 13.10, then, anything herein
contained to the contrary notwithstanding, the Trustee or

                                       82
<PAGE>   89

such Paying Agent shall have full power and authority to receive such monies and
apply the same to the purpose for which they were received on the date payment
is due and, unless such payment is not made on that date, shall not be affected
by any notice to the contrary which may be received by it on or after the date
upon which such monies become due and payable. Any notice required or permitted
to be given to the Trustee by the Company, a holder of Senior Indebtedness or
any Designated Senior Holder shall be in writing and shall be sufficient for
every purpose hereunder if in writing and either (i) sent via facsimile to the
Trustee to a facsimile number provided by the Trustee, the receipt of which
shall be confirmed via telephone, or (ii) mailed, first class postage prepaid,
or sent by overnight carrier, to the Trustee addressed to it attention of its
Corporate Trustee Administration Department, at the Corporate Trust Office or at
any other address furnished in writing to the Company, such holder of Senior
Indebtedness or such Designated Senior Holder.

         Subject to the provisions of Section 6.1 hereof, the Trustee shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Indebtedness or Designated Senior
Holder to establish that such notice has been given by such holder of Senior
Indebtedness or Designated Senior Holder. In the event that the Trustee
determines in good faith that further evidence is required with respect to the
right of any Person representing himself to be a holder of Senior Indebtedness
or Designated Senior Holder to participate in any payment or distribution
pursuant to this Article, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article, or 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 13.11. Reliance On Judicial Order or Certificate of Liquidating
                        Agent.

         Upon any payment or distribution of assets of the Company referred to
in this Article, the Trustee, subject to the provisions of Section 6.1 hereof,
and the Holders of the Securities shall be entitled to rely upon any order or
decree entered by any court of competent jurisdiction in which such Proceeding
is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee for the benefit of creditors, agent or other Person
making such payment or distribution, delivered to the Trustee or to the Holders
of Securities, for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution,

                                       83

the holders of the Senior Indebtedness, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article, provided that the foregoing shall apply only if such
court has been apprised of the provisions of this Article.

         SECTION 13.12. Trustee Not Fiduciary For Holders of Senior
                        Indebtedness.

         Subject to the provisions of Section 6.1, the Trustee shall not be
deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall
not be liable to any such holders if it shall in good faith mistakenly pay over
or distribute to Holders of Securities or to the Company or to any other Person
cash, property or securities to which any holders of Senior Indebtedness shall
be entitled by virtue of this Article or otherwise.

         SECTION 13.13. Rights of Trustee As Holder of Senior Indebtedness;
                        Preservation of Trustee's Rights.

         The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article with respect to any Senior Indebtedness which
may at any time be held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.

         Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.7 hereof.

         SECTION 13.14. Article Applicable To Paying Agents.

         In case at any time any Paying Agent other than the Trustee (or the
Company or an Affiliate of the Company) shall have been appointed by the Company
and be then acting hereunder, the term "Trustee" as used in this Article shall
in such case (unless the context otherwise requires) be construed as extending
to and including such Paying Agent within its meaning as fully for all intents
and purposes as if such Paying Agent were named in this Article in addition to
or in place of the Trustee.

         SECTION 13.15. Reliance by Holders of Senior Indebtedness on
                        Subordination Provisions.

         Each Holder by accepting a Security acknowledges and agrees that the
foregoing subordination provisions are, and are intended to be, an inducement
and a consideration to each holder of any Senior Indebtedness, whether such
Senior Indebtedness was created or acquired before or after the issuance of the
Securities, to acquire and continue to hold, or to continue to hold, such Senior
Indebtedness and such holder of Senior Indebtedness shall be

                                       84
<PAGE>   91

deemed conclusively to have relied on such subordination provisions in acquiring
and continuing to hold, or in continuing to hold, such Senior Indebtedness.

                                   ARTICLE XIV

                            MISCELLANEOUS PROVISIONS

         SECTION 14.1. No Recourse Against Others.

         An incorporator or any past, present or future director, officer,
employee or stockholder, as such, of the Company shall not have any liability
for any obligations of the Company under the Securities or this Indenture or for
any claim based on, in respect of or by reason of such obligations or their
creation. By accepting a Security, each Holder shall waive and release all such
liability. Such waiver and release shall be part of the consideration for the
issue of the Securities.

         SECTION 14.2. Additional Interest.

         Whenever there is mentioned in this Indenture, in any context, the
payment of the principal of, premium, if any, or interest on, or in respect of,
any Security of any series, such mention shall be deemed to include mention of
the payment of Additional Interest provided for by the terms of such series of
Securities to the extent that, in such context, Additional Interest is, were or
would be payable in respect thereof pursuant to such terms and express mention
of the payment of Additional Interest in any provisions hereof shall not be
construed as excluding Additional Interest in those provisions hereof where such
express mention is not made.

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