appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective upon action by the requisite percentage of Holders
when such instrument or instruments are delivered to the Trustee and, where it
is hereby expressly required, to the Company. Such instrument or instruments

referred to as the "ACT" of the Holders signing such instrument or instruments.
Proof of execution of any such instrument or of a writing appointing any such
agent shall be sufficient for any purpose of this Indenture and (subject to

instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual

               (c) The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining the
Holders of Debentures entitled to give or take any request, demand,
authorization, direction, notice, consent, waiver or other action, or to vote on
any action, authorized or permitted to be given or taken by Holders of
Debentures. If not set by the Company prior to the first solicitation of a
Holder of Debentures made by any Person in respect of any such action, or, in
the case of any such vote, prior to such vote, the record date for any such
action or vote shall be the 30th day (or, if later, the date of the most recent
list of Holders required to be provided pursuant to Section 7.1) prior to such
first solicitation or vote, as the case may be. With regard to any record date
for action to be taken by the Holders of Debentures, only the Holders of
Debentures on such date (or their duly designated proxies) shall be entitled to
give or take, or vote on, the relevant action.

               (d) The ownership of Debentures shall be proved by the Debenture
Register.

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

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

               Section 1.5 NOTICES, ETC., TO TRUSTEE AND COMPANY.

               Except as otherwise expressly provided herein, any request,
demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

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

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

               Section 1.6  NOTICE TO HOLDERS; WAIVER.

               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 his address as it appears in the Debenture Register,
not later than the latest date (if any), and not earlier than the earliest date
(if any), prescribed for the giving of such notice. 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.

               If by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

               Section 1.7  CONFLICT WITH TRUST INDENTURE ACT.

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

               Section 1.8  EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

               Section 1.9  SUCCESSORS AND ASSIGNS.

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

               Section 1.10 SEPARABILITY CLAUSE.

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

TO THIS INDENTURE AND THE DEBENTURES, AND IRREVOCABLY ACCEPTS FOR ITSELF AND IN
RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, JURISDICTION OF THE
AFORESAID COURTS. EACH OBLIGOR IRREVOCABLY WAIVES, TO THE FULLEST EXTENT THEY
MAY EFFECTIVELY DO SO UNDER APPLICABLE LAW, ANY OBJECTION WHICH IT MAY NOW OR
HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING
BROUGHT IN ANY SUCH COURT AND ANY CLAIM THAT ANY SUCH SUIT, ACTION OR PROCEEDING
BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

               (c) The Company hereby irrevocably appoints _____________________

MAILING, AND SHALL BE LEGAL AND BINDING UPON THE COMPANY FOR ALL PURPOSES,
NOTWITHSTANDING ANY FAILURE OF THE PROCESS AGENT TO MAIL COPIES OF SUCH LEGAL
PROCESS TO THE COMPANY OR ANY FAILURE ON THE PART OF THE COMPANY TO RECEIVE THE
SAME. The Company confirms that it has instructed the Process Agent to mail to
it, upon service of process being made on the Process Agent pursuant to

the Process Agent in writing. The Company agrees that it will at all times
maintain a process agent to receive service of process in the County of New York
on its behalf with respect to this Indenture and the Debentures. If for any
reason the Process Agent or any successor thereto shall no longer serve as such

irrevocably shall appoint a substitute process agent acceptable to the Trustee

Debentures (other than a provision of the Debentures which specifically states

               This Debenture is one of a duly authorized issue of securities of
the Company (herein called the "DEBENTURES"), issued under an Indenture, dated
as of _________, 1998 (herein called the "INDENTURE"), between the Company and
_______________________, as Trustee (herein called the "TRUSTEE", which term
includes any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee and the Holders of the Debentures and of the terms upon
which the Debentures are, and are to be, authenticated and delivered. This
Debenture is one of the Debentures designated on the face hereof, limited in
aggregate principal amount to $__________.

               The Company may redeem, at its option, up to ___% of the original
aggregate principal amount of the Debentures at any time and from time to time
at a redemption price of ____% of the principal amount of the Debentures
redeemed, plus accrued and unpaid interest thereon. In the event of redemption
of this Debenture in part only, a new Debenture or Debentures of like tenor for
the unredeemed portion hereof will be issued in the name of the Holder hereof
upon the cancellation hereof.

manner and to the extent set forth in the Indenture, to the prior payment in
full of all Senior Indebtedness of the Company, whether outstanding on the date

Holder by his acceptance hereof agrees to be bound by such provisions and

as may be necessary or appropriate to effectuate the subordination provided for
in the Indenture and appoints the Trustee his attorney-in-fact for such
purposes.

restrictive covenants, in each case upon compliance by the Company with certain
conditions set forth therein, which provisions apply to this Debenture.

obligations of the Company and the rights of the Holders of the Debentures to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the Debentures at
the time Outstanding. The Indenture also contains provisions permitting the
Holders of specified percentages in principal amount of the Debentures at the
time Outstanding, on behalf of the Holders of all Debentures, to waive certain
past defaults under the Indenture and their consequences. Any such consent or
waiver by the Holder of this Debenture shall be conclusive and binding upon such
Holder and upon all future Holders of this Debenture and of any Debenture issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Debenture.

Debenture or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and any
premium and interest on this Debenture at the times, place and rate, and in the
coin or currency, herein prescribed.

therein set forth, the transfer of this Debenture is registrable in the
Debenture Register, upon surrender of this Debenture for registration of
transfer at the office or agency of the Company in any place where the principal
of and any premium and interest on this Debenture are payable, duly endorsed by,
or accompanied by a written instrument of transfer in form satisfactory to the
Company and the Debenture Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Debentures of
like tenor, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees.

               The Debentures are issuable only in registered form without
coupons in denominations of $20 and any integral multiple thereof. As provided
in the Indenture and subject to certain limitations therein set forth,
Debentures are exchangeable for a like aggregate principal amount of Debentures
of like tenor of a different authorized denomination, as requested by the Holder
surrendering the same.

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

executed by the Trustee by manual signature of an Responsible Officer, and such
certificate upon any Debenture shall be conclusive evidence, and the only
evidence, that such Debenture has been duly authenticated and delivered
hereunder. Notwithstanding the foregoing, if any Debenture shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Debenture to the Trustee for cancellation as
provided in Section 3.10, for all purposes of this Indenture such Debenture
shall be deemed never to have been authenticated and delivered hereunder and
shall never be entitled to the benefits of this Indenture.

          Section 3.5    TEMPORARY DEBENTURES.

          Pending the preparation of definitive Debentures, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Debentures which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Debentures in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Debentures may determine, as evidenced by their
execution of such Debentures.

          If temporary Debentures are issued, the Company will cause definitive
Debentures to be prepared without unreasonable delay. After the preparation of
definitive Debentures, the temporary Debentures shall be exchangeable for
definitive Debentures upon surrender of the temporary Debentures at the office
or agency of the Company in a Place of Payment, without charge to the Holder.
Upon surrender for cancellation of any one or more temporary Debentures 



                                       21


<PAGE>   27

the Company shall execute and the Trustee shall authenticate and deliver in
exchange therefor one or more definitive Debentures of any authorized
denominations and of a like aggregate principal amount and tenor. Until so
exchanged the temporary Debentures shall in all respects be entitled to the same
benefits under this Indenture as definitive Debentures of such tenor.

          Section 3.6    REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE.

          The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office being herein
sometimes collectively referred to as the "DEBENTURE REGISTER") in which,
subject to such reasonable regulations as it may prescribe, the Company shall
provide for the registration of Debentures and of transfers of Debentures. The
Trustee is hereby appointed "Debenture Registrar" for the purpose of registering
Debentures and transfers of Debentures as herein provided.

          Upon surrender for registration of transfer of any Debenture at the
office or agency in a Place of Payment, the Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Debentures of any authorized denominations and
of a like aggregate principal amount and tenor.

          At the option of the Holder, Debentures may be exchanged for other
Debentures of any authorized denominations and of a like aggregate principal
amount and tenor, upon surrender of the Debentures to be exchanged at such
office or agency. Whenever any Debentures are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Debentures which the Holder making the exchange is entitled to receive.

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

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

          No service charge shall be made for any registration of transfer or
exchange of Debentures, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Debentures, other than
exchanges pursuant to Section 3.5, 3.6, 3.7, 4.2 or 13.7 not involving any
transfer.

          The Company shall not be required (i) to issue, register the transfer
of or exchange Debentures during a period beginning at the opening of business
15 days before the day of the mailing of a notice of redemption of Debentures
selected for redemption under Section 13.3 and ending at the close of business
on the day of such mailing, or (ii) to register the transfer of or 




                                       22



<PAGE>   28

exchange any Debenture so selected for redemption in whole or in part, except
the unredeemed portion of any Debenture being redeemed in part.

          Section 3.7    MUTILATED, DESTROYED, LOST AND STOLEN DEBENTURES.

          If any mutilated Debenture is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Debenture of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

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

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

          Upon the issuance of any new Debenture under this Section 3.7, 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 Debenture issued pursuant to this Section 3.7 in lieu of any
destroyed, lost or stolen Debenture shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Debenture 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 Debentures duly issued hereunder.

          The provisions of this Section 3.7 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 Debentures.

          Section 3.8    PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

          Interest on any Debenture which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid in immediately
available funds to the Person in whose name that Debenture (or one or more
Predecessor Debentures) is registered at the close of business on the Regular
Record Date for such interest.

          Any interest on any Debenture which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called
"DEFAULTED INTEREST") shall forthwith cease to be payable to the Holder on the
relevant Regular Record Date by virtue of having been 


                                       23



<PAGE>   29

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 Debentures (or their respective Predecessor
     Debentures) 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 Debenture 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 Debentures at his address as it appears in the Debenture
     Register, not less than 10 days prior to such Special Record Date. Notice
     of the proposed payment of such Defaulted Interest and the Special Record
     Date therefor having been so mailed, such Defaulted Interest shall be paid
     to the Persons in whose names the Debentures (or their respective
     Predecessor Debentures) are registered at the close of business on such
     Special Record Date and shall no longer be payable pursuant to the
     following clause (2).

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

          Subject to the foregoing provisions of this Section 3.8, each
Debenture delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Debenture shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Debenture.

          Section 3.9    PERSONS DEEMED OWNERS.

          Prior to due presentment of a Debenture for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Debenture is registered as the owner of such
Debenture for the purpose of receiving payment of principal of and any premium
and (subject to Section 3.8) any interest on such 



                                       24


<PAGE>   30

Debenture and for all other purposes whatsoever, whether or not such Debenture
be overdue, and neither the Company, the Trustee nor any agent of the Company or
the Trustee shall be affected by notice to the contrary.

          So long as the Global Debenture Holder is the registered owner of any
Debentures, the Global Debenture Holder will be considered the sole Holder under
this Indenture of any Debentures evidenced by the Global Debenture for the
purposes of receiving payment on the Debentures, receiving notices, and for all
other purposes under this Indenture and the Debentures. Beneficial owners of
Debentures evidenced by the Global Debenture will not be considered the owners
or Holders thereof under this Indenture for any purpose, including with respect
to the giving of any directions, instructions or approvals to the Trustee
thereunder. Neither the Company nor the Trustee will have any responsibility or
liability for any aspect of the records of the Depositary or for maintaining,
supervising or reviewing any records of the Depositary relating to the
Debentures.

          Section 3.10   CANCELLATION.

          All Debentures surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it. The Company may at any time deliver to the
Trustee for cancellation any Debentures previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may
deliver to the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Debentures previously authenticated hereunder which the Company
has not issued and sold, and all Debentures so delivered shall be promptly
canceled by the Trustee. No Debentures shall be authenticated in lieu of or in
exchange for any Debentures canceled as provided in this Section 3.10, except as
expressly permitted by this Indenture. All canceled Debentures held by the
Trustee shall be disposed of as directed by a Company Order.

          Section 3.11   COMPUTATION OF INTEREST.

          Interest on the Debentures shall be computed on the basis of a 360-day
year of twelve 30-day months.

          Section 4.1    APPLICABILITY OF ARTICLE

          Each Global Debenture shall be subject to this Article Four.

          Section 4.2.   BOOK-ENTRY PROVISIONS FOR GLOBAL DEBENTURE

          (a) Members of, or participants in, the Depositary ("AGENT MEMBERS")
shall have no rights under this Indenture with respect to any Global Debenture
held on their behalf by the 



                                       25



<PAGE>   31

Depositary or under the Global Debenture, and the Depositary may be treated by
the Company, the Trustee and any agent of the Company or the Trustee as the
absolute owner of the Global Debenture for all purposes whatsoever. Any Holder
of the Global Debenture shall, by acceptance of such Global Debenture, agree
that the transfers of beneficial interests in such Global Debenture may be
effected only through a book-entry system maintained by the Holder of such
Global Debenture (or its agent), and that ownership of a beneficial interest in
the Global Debenture shall be required to be reflected in a book-entry system.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or an agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depositary
or impair, as between the Depositary and its Agent Members, the operation of
customary practices governing the exercise of the rights of a Holder of any
Debenture.

          (b) The Depositary must, at the time of its designation and at all
times while it serves as Depositary, be a clearing agency registered under the
Exchange Act and any other applicable statute or regulation.

          (c) Notwithstanding any other provision of this Section, unless and
until it is exchanged in whole or in part for individual Debentures represented
thereby, a Global Debenture representing all or a portion of the Debentures may
not be transferred except as a whole by the Depositary to a nominee of such
Depositary or by a nominee of such Depositary to such Depositary or another
nominee of such Depositary or by such Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary. Interests of
beneficial owners in the Global Debentures (each an "INTEREST") may be
transferred to one beneficial owner or to another Agent Member or exchanged for
definitive Debentures in accordance with the rules and procedures of the
Depositary and the provisions of this Indenture. In addition, definitive
Debentures shall be transferred to all beneficial owners in exchange for their
beneficial interests in Global Debentures if (i) the Depositary for the
Debentures notifies the Company that the Depositary is unwilling or unable to
continue as Depositary for the Global Debentures or is no longer eligible to
serve as Depositary pursuant to the terms of this Indenture and a successor
Depositary is not appointed by the Company within 90 days after delivery of such
notice; (ii) the Company, at its sole discretion, notifies the Trustee in
writing that it elects to cause the issuance of definitive Debentures under this
Indenture, then the Company shall execute; or (iii) there shall have occurred
and be continuing a Default with respect to any Debentures represented by the
Global Debentures; and the Trustee shall, upon receipt of a Company Order in
accordance with Section 3.4, authenticate and deliver, definitive Debentures in
an aggregate principal amount equal to the principal amount of the Global
Debentures in exchange for such Global Debentures. If specified by the Company
pursuant to Section 3.4, the Depositary may surrender a Global Debenture in
exchange in whole or in part for Debentures of like tenor and terms and in
definitive form on such terms as are acceptable to the Company, the Trustee and
the Depositary.

          (d) In connection with the transfer of any Interest from one
beneficial owner to another Agent Member not taking a definitive Debenture, but
an Interest, pursuant to paragraph (c) of this Section 4.2, the Depositary shall
reflect on its books and records the date, the name of the transferor and
transferee, and the amount of the Interest transferred.

          (e) In connection with the transfer of Global Debentures to beneficial
owners pursuant to the third sentence of paragraph (c) or (h) of this Section
4.2, the Global Debentures shall be deemed to be surrendered to the Trustee for
cancellation, and the Company shall execute and the Trustee upon receipt of a
Company Order for the authentication and delivery of definitive Debentures shall
authenticate and deliver, without service charge:

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

               (ii)    to such Depositary a new Global Debenture of like tenor
     and terms and in an authorized denomination equal to the difference, if
     any, between the principal amount of the surrendered Global Debenture and
     the aggregate principal amount of Debentures delivered to Holders thereof.

          Notwithstanding any other provision of this Indenture, any Debenture
authenticated and delivered upon registration of transfer of, or in exchange
for, or in lieu of, any Global Debenture shall also be a Global Debenture and
shall bear the legend specified in Section 2.4 hereof except for any Debenture
authenticated and delivered in exchange for, or upon registration of transfer
of, a Global Debenture pursuant to the preceding sentence.

          (f)  The Holder of any Global Debenture may grant proxies and
otherwise authorize any person, including Agent Members and persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Debentures.

          (g)  Upon the exchange of a Global Debenture in its entirety for
Debentures in definitive form, such Global Debenture shall be canceled by the
Trustee.

          (h)  Notwithstanding anything herein to the contrary, if at any time
the Depositary for the Debentures notifies the Company that it is unwilling or
unable to continue as a Depositary for the Debentures or if at any time the
Depositary for the Debentures shall no longer be registered or in good standing
under the Exchange Act, or other applicable statute or regulation, the Company
shall appoint a successor Depositary with respect to the Debentures. If a
successor Depositary for the Debentures is not appointed by the Company within
90 days after the Company receives such notice or becomes aware of such
condition, the Company will execute, and the Trustee, upon Company Request, will
authenticate and deliver Debentures in definitive form in an aggregate principal
amount equal to the principal amount of the Global Debenture or Global
Debentures representing Debentures in exchange for such Global Debenture or
Global Debentures.

                                    REMEDIES

          Section 5.1    EVENTS OF DEFAULT.

          An "EVENT OF DEFAULT" as used herein is any one of the following:

          (a) a default in the payment of interest on the Debentures when due,
     continued for 30 days;

          (b) a default in the payment of principal of and premium, if any, on
     any Debenture when due at its Stated Maturity, upon optional redemption,
     upon required repurchase, upon declaration of acceleration or otherwise;

          (c) [Intentionally omitted.]

          (d) the failure by the Company to comply with any of its obligations
     in Section 7.4 and 30 days or more shall have expired after a Senior
     Officer of the Company first becomes aware of such failure;

          (e) the failure by the Company to comply, for 30 days after the notice
     specified below, in any material respect in the performance of or to breach
     any covenant, representation or warranty contained in this Indenture; or

          (f) a decree, judgment or order by a court of competent jurisdiction
     shall have been entered adjudging the Company as bankrupt or insolvent, or
     approving as properly filed a petition seeking reorganization of the
     Company under any bankruptcy or similar law, and such decree or order shall
     have continued undischarged and unstayed for a period of 60 days; or a
     decree or order of a court of competent jurisdiction over the appointment
     of a receiver, liquidator, trustee or assignee in bankruptcy or insolvency
     of the Company, or of the property of any such person, or for the winding
     up for liquidation of the affairs of any such person, shall have been
     entered, and such decree, judgment or order shall have remained in force
     undischarged and unstayed for a period of 60 days; or the Company shall
     institute proceedings to be adjudicated a voluntary bankrupt, or shall
     consent to the filing of a bankruptcy proceeding against it, or shall file
     a petition or answer or consent seeking reorganization under any bankruptcy
     or similar law or similar statute, or shall consent to the filing of any
     such petition, or shall consent to the appointment of a custodian,
     receiver, liquidator, trustee or assignee in bankruptcy or insolvency of it
     or any of its assets or property, or shall make a general assignment for
     the benefit of creditors, or shall admit in writing its inability to pay
     its debts generally as they become due, or shall become insolvent or fail
     generally to pay its debts as they become due.

          A Default under subsection (e) is not an Event of Default until the
Trustee or the Holders of at least 25% in principal amount of the Outstanding
Debentures notify the Company of the Default and the Company does not cure the
Default within 30 days after receipt of the notice. 


                                       28


<PAGE>   34

The notice must specify the Default, demand that it be remedied and state that
the notice is a "NOTICE OF DEFAULT."

          Section 5.2   ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

          If an Event of Default (other than an Event of Default specified in
clause (f) of Section 5.1) with respect to Debentures at the time Outstanding
occurs and is continuing, then in every such case the Trustee or the Holders of
not less than 25% in principal amount of the Outstanding Debentures may declare
the principal amount of all of the Debentures to be due and payable immediately,
by a notice in writing to the Company (and to the Trustee if given by Holders),
and upon any such declaration such principal amount (or specified amount) shall
become immediately due and payable. If any Event of Default specified in clause
(g) of Section 5.1 occurs, such principal amount shall automatically become and
be immediately due and payable without any declaration or other act on the part
of the Trustee or any Holder.

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

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

               (A) all overdue interest on all Debentures,

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

               (C) to the extent that payment of such interest is lawful,
          interest upon overdue interest at the rate or rates prescribed
          therefor in such Debentures, and

               (D) all sums paid or advanced by the Trustee hereunder and the
          reasonable compensation, expenses, disbursements and advances of the
          Trustee, its agents and counsel;

     and

          (2)  all Events of Default with respect to Debentures, other than the
     non-payment of the principal of Debentures which have become due solely by
     such declaration of acceleration, have been cured or waived as provided in
     Section 5.13.

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

          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 interest on any Debenture
     when such interest becomes due and payable and such default continues for a
     period of 30 days, or

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Debentures, the whole amount then due and payable on such
Debentures for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Debentures, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

          If 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 (or, at the
direction of Holders of not less than 25% of the Outstanding Debentures shall),
in addition to any other remedies available to it, 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 Debentures 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 Debentures, wherever
situated. If an Event of Default with respect to Debentures occurs and is
continuing, the Trustee may in its discretion proceed to protect and enforce its
rights and the rights of the Holders of Debentures 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.

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

advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 6.7.

          No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Debentures 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, the Trustee may vote on behalf of the Holders for the election of a
trustee in bankruptcy or similar official and may be a member of a creditors' or
other similar committee.

          Section 5.5    TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF 
                         DEBENTURES.

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

          Section 5.6    APPLICATION OF MONEY COLLECTED.

          Subject to Article Twelve of this Indenture, any money collected by
the Trustee pursuant to this Article Five shall be applied in the following
order, at the date or dates fixed by the Trustee and, in case of the
distribution of such money on account of principal or any premium or interest,
upon presentation of the Debentures and the notation thereon of the payment if
only partially paid and upon surrender thereof if fully paid:

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

          SECOND: To the payment of the amounts then due and unpaid for

     and payable on such Debentures for principal and any premium and interest,
     respectively.

          Section 5.7    LIMITATION ON SUITS.

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

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



                                       31



<PAGE>   37

          (2) the Holders of not less than 25% in principal amount of the
     Outstanding Debentures 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
     security or 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 Debentures;

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

          Section 5.8    UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL,
                         PREMIUM AND INTEREST.

          Notwithstanding any other provision in this Indenture, the Holder of
any Debenture shall have the right, which is absolute and unconditional, to
receive payment of the principal of and any premium and (subject to Section 3.8)
any interest on such Debenture on the Stated Maturity or maturities expressed in
such Debenture (or, in the case of redemption or repurchase, on the Redemption
Date or Repurchase Date), and to institute suit for the enforcement of any such
payment, and such rights shall not be impaired without the consent of such
Holder.

          Section 5.9    RESTORATION OF RIGHTS AND REMEDIES.

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

          Section 5.10   RIGHTS AND REMEDIES CUMULATIVE.

          Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Debentures in the last paragraph
of Section 3.7, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be 



                                       32



<PAGE>   38

exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

          Section 5.11   DELAY OR OMISSION NOT WAIVER.

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

          Section 5.12   CONTROL BY HOLDERS.

          The Holders of a majority in principal amount of the Outstanding
Debentures 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 Debentures,
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 any such direction if the Trustee in good
     faith shall, by a Responsible Officer or Officers of the Trustee, determine
     that the proceeding so directed would be unduly prejudicial to the rights
     of any other Holder or would involve the Trustee in personal liability.

          Section 5.13   WAIVER OF PAST DEFAULTS.

          The Holders of not less than a majority in principal amount of the
Outstanding Debentures may on behalf of the Holders of all the Debentures waive
any past default hereunder and its consequences, except a default

          (1) in the payment of the principal of or any premium or interest on
     any Debenture, or

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


                                       33



<PAGE>   39

          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 Debentures
by his acceptance thereof shall be deemed to have agreed, that any court may in
its discretion require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section 5.14 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 Debentures, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium, if any) or
interest on any Debentures on or after the Stated Maturity or maturities
expressed in such Debentures (or, in the case of redemption or repurchase, on or
after the Redemption Date or Repurchase Date).

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


                                   ARTICLE SIX

                                   THE TRUSTEE

          Section 6.1    CERTAIN DUTIES AND RESPONSIBILITIES.

          The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act. Whether or not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section 6.1. If an Event of Default occurs (and is not cured), the Trustee,
in the exercise of its power, must use the degree of care of a prudent man in
the conduct of his own affairs. Subject to the requirement in the foregoing
sentence, the Trustee is under no 


                                       34



<PAGE>   40

obligation to exercise any of its rights or powers under this Indenture at the
request of any Holder, unless such Holder shall have offered to the Trustee
security and indemnity satisfactory to it against any loss, liability or expense
and then only to the extent required by the terms of this Indenture.

          Section 6.2    NOTICE OF DEFAULTS.

          If a Default occurs and is continuing and is known to the Trustee, the
Trustee shall mail to each Holder notice of the Default within 60 days after it
occurs. Except in the case of a Default in the payment of principal of, premium,
if any, or interest on any Debenture, the Trustee may withhold notice if and so
long as a committee of its trust officers determines that withholding notice is
not opposed to the interest of the Holders.

          Section 6.3    CERTAIN RIGHTS OF TRUSTEE.

          Subject to the provisions of Section 6.1:

          (a) the Trustee may rely and shall be protected in acting or
     refraining from acting upon any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,

     evidenced by a Company Request or Company Order and any resolution of the
     Board of Directors may be sufficiently evidenced by a Board Resolution;

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

          (d) 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 in good faith and in reliance thereon;

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

          (f) the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, Debenture, other evidence of indebtedness or other paper
     or document, but the Trustee, in its discretion, may make such further
     inquiry or investigation into such facts or matters as it may see fit, and,
     if the 




                                       35


<PAGE>   41

     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled to examine the books, records and premises of the
     Company, personally or by agent or attorney; and

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

          Section 6.4    NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF DEBENTURES.
 
          The recitals contained herein and in the Debentures, except the
Trustee's certificate of authentication, shall be taken as the statements of the
Company, and the Trustee or any Authenticating Agent assumes no responsibility
for their correctness. The Trustee makes no representations as to the validity
or sufficiency of this Indenture or of the Debentures. The Trustee or any
Authenticating Agent shall not be accountable for the use or application by the
Company of Debentures or the proceeds thereof.

          Section 6.5    MAY HOLD DEBENTURES.

          The Trustee, any Authenticating Agent, any Paying Agent, any Debenture
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Debentures and, subject to Sections
6.8 and 6.13, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Debenture
Registrar or such other agent.

          Section 6.6    MONEY HELD IN TRUST.

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

          Section 6.7    COMPENSATION AND REIMBURSEMENT.

          The Company agrees:

          (1) to pay to the Trustee from time to time reasonable compensation
     for all services rendered by it hereunder (which compensation shall not be
     limited by any provision of law in regard to the compensation of a trustee
     of an express trust);

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


                                       36



<PAGE>   42

          (3) to indemnify the Trustee for, and to hold it harmless against, any
     loss, liability or expense incurred without negligence or bad faith on its
     part, arising out of or in connection with the acceptance or administration
     of the trust or trusts hereunder, including the reasonable costs and
     expenses of defending itself against any claim or liability in connection
     with the exercise or performance of any of its powers or duties hereunder;
     and

          (4) when the Trustee incurs any expenses or renders any services after
     the occurrence of an Event of Default specified in Section 5.1(g), such
     expenses and the compensation for such services are intended to constitute
     expenses of administration under the Bankruptcy Code or any similar federal
     or state law for the relief of debtors.

          As security for the performance of the obligations of the Company
under this Section 6.7, the Trustee shall have a lien prior to the Debentures
upon all property and funds held or collected by the Trustee as such, except
funds (i) held in trust for the payment of principal of and interest on
Debentures or (ii) held in the Trustee's capacity as Paying Agent.

          The obligations of the Company under this Section 6.7 to compensate
and indemnify the Trustee and each predecessor Trustee and to pay or reimburse
the Trustee and each predecessor Trustee for expenses, disbursements and
advances shall constitute an additional obligation hereunder and shall survive
the satisfaction and discharge of this Indenture and the resignation or removal
of the Trustee and each predecessor Trustee.

          Section 6.8    DISQUALIFICATION; CONFLICTING INTERESTS.

          If the Trustee has or shall acquire a conflicting interest within the

Person that is eligible pursuant to the Trust Indenture Act to act as such and
has a combined capital and surplus of at least $10,000,000. If such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of any supervising or examining authority, then for the purposes of
this Section 6.9, the combined capital and surplus of such Person shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 6.9, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article Six.

          Section 6.10   RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

          (a) No resignation or removal of the Trustee and no appointment of a

acceptance of 


                                       37


<PAGE>   43

appointment by the successor Trustee in accordance with the applicable
requirements of Section 6.11.

          (b) The Trustee may resign at any time with respect to the Debentures
by giving written notice thereof to the Company. If the instrument of acceptance
by a successor Trustee required by Section 6.11 shall not have been delivered to
the Trustee within 30 days after the giving of such notice of resignation, the
resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Debentures.

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

          (d)  If at any time:

               (1) the Trustee shall fail to comply with Section 6.8 after
     written request therefor by the Company or by any Holder who has been a
     bona fide Holder of a Debenture for at least six months, or

               (2) the Trustee shall cease to be eligible under Section 6.9 and
     shall fail to resign after written request therefor by the Company or by
     any Holder who has been a bona fide holder of a Debenture for at least six
     months, or

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

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all securities, or (ii) subject to Section 5.14, any
Holder who has been a bona fide Holder of a Debenture for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Debentures and the appointment of a successor Trustee or Trustees.

          (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Debentures, the Company, by a Board Resolution, shall promptly
appoint a successor Trustee or Trustees with respect to the Debentures and shall
comply with the applicable requirements of Section 6.11. If, within one year
after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to the Debentures shall be appointed
by Act of the Holders of a majority in principal amount of the Outstanding
Debentures delivered to the Company and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 6.11, become the
successor Trustee with respect to the Debentures and to that extent supersede
the successor Trustee appointed by the Company. If no successor Trustee with
respect to the Debentures shall have been so appointed by the Company or the
Holders and accepted appointment in the manner 



                                       38

Debenture for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Debentures.

          (f) The Company shall give notice of each resignation and each removal
of the Trustee with respect to the Debentures and each appointment of a
successor Trustee with respect to the Debentures to all Holders of Debentures in
the manner provided in Section 1.6. Each notice shall include the name of the
successor Trustee with respect to the Debentures and the address of its
Corporate Trust Office.

          Section 6.11   ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

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

          (b) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) of this Section 6.11.

          (c) 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 Six.

          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 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 Six,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Debentures 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 Debentures so authenticated with the same effect
as if such successor Trustee had itself authenticated such Debentures.

          If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Debentures), the Trustee shall be subject to the

the Company (or any such other obligor).

          Section 6.14   APPOINTMENT OF AUTHENTICATING AGENT.

          The Trustee may appoint an Authenticating Agent or Agents (which may
be an affiliate of the Company) with respect to the Debentures which shall be
authorized to act on behalf of the Trustee to authenticate Debentures issued
upon original issue and upon exchange, registration of transfer or partial
redemption thereof or pursuant to Section 3.7, and Debentures 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 Debentures by the Trustee or the Trustee's certificate of authentication,
such reference shall be deemed to include authentication and delivery on behalf
of the Trustee by an Authenticating Agent and a certificate of authentication
executed on behalf of the Trustee by an Authenticating Agent. Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a corporation organized and doing business under the laws of the United
States of America, any state thereof or the District of Columbia, authorized
under such laws to act as Authenticating Agent, having a combined capital and
surplus of not less than $500,000,000 and subject to supervision or examination
by 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 6.14,
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 6.14, such
Authenticating Agent shall resign immediately in the manner and with the effect
specified in this Section 6.14.

          Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section 6.14, without the execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent.

          An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and 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 6.14, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall mail
written notice of such appointment by first-class mail, postage prepaid, to all
Holders of Debentures with respect to which such Authenticating Agent 


                                       40


<PAGE>   46

will serve, as their names and addresses appear in the Debenture Register. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section 6.14.

          Unless the Authenticating Agent has been appointed by the Trustee at
the request of the Company, the Trustee agrees to pay to each Authenticating
Agent from time to time reasonable compensation for its services under this
Section 6.14, and the Trustee shall be entitled to be reimbursed for such
payments, subject to the provisions of Section 6.7.

          If an appointment is made pursuant to this Section 6.14, the
Debentures 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 Debentures designated and referred to in the
     within-mentioned Indenture.

          Section   7.2 PRESERVATION OF INFORMATION; COMMUNICATIONS TO HOLDERS.

addresses of Holders received by the Trustee in its capacity as Debenture

          (b) The rights of the Holders to communicate with other Holders with
respect to their rights under this Indenture or under the Debentures, and the
corresponding rights and privileges of the Trustee, shall be as provided by the
Trust Indenture Act.

          (c) Every Holder of Debentures, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
nor any agent of either of them shall be held accountable by reason of any
disclosure of information as to names and addresses of Holders made pursuant to
the Trust Indenture Act.

          Section 7.3    REPORTS BY TRUSTEE.

          (a) The Trustee shall transmit to Holders such reports concerning the

Trust Indenture Act at the times and in the manner provided pursuant thereto. To
the extent that any such report is required by the Trust Indenture Act with

          Section 9.2    SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

          (a)  Except as otherwise provided in Section 9.2(b), with the written
     consent of the Holders of a majority in principal amount of the Outstanding
     Debentures, by Act of such 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 or waiving any of the provisions of this Indenture or of

          maturity of any installment of interest on, any Debenture, or reduce
          the principal amount thereof or the rate of interest thereon or any
          premium payable upon the redemption or repurchase thereof, or change
          the coin or currency or property in which the principal of any
          Debenture or any premium or the interest thereon is payable, or impair
          the right to institute suit for the enforcement of any such payment
          after the Stated Maturity or due date thereof (or, in the case of
          redemption, after the Redemption Date), or affect the ranking (in
          terms of right or time of payment) of the Debentures,

               (B) [Intentionally omitted],

          Defaults hereunder and their consequences) provided for in this
          Indenture,

               (D) modify any provision of Article Twelve with respect to the
          subordination of the Debentures;

               (E) modify any provision of Section 13.2 or the definitions used

          5.13, 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 Debenture affected
          thereby.

          (b)  It shall not be necessary for any Act of Holders under this
     Section 9.2 to approve the particular form of any proposed supplemental
     indenture, but it shall be sufficient if such Act and such notice 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 Nine or the modifications
thereby of the trusts created by this Indenture, the Trustee shall receive, and
(subject to Section 6.1) shall be fully protected in relying upon, an Opinion of
Counsel stating that this Indenture, as amended by such supplemental indenture,
constitutes the legal, valid and binding obligation of the Company, enforceable
against each of them in accordance with its terms.

          Section 9.4    EFFECT OF SUPPLEMENTAL INDENTURES.

          Upon the execution of any supplemental indenture under this Article
Nine, this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes; and
every Holder of Debentures theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby and entitled to the benefits thereof.

          Section 9.5    CONFORMITY WITH TRUST INDENTURE ACT.

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

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

          Section 9.7    NOTICE OF SUPPLEMENTAL INDENTURE.

          After an supplemental indenture hereunder becomes effective, the

indenture.

          Section 10.1   PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

          The Company covenants and agrees for the benefit of the Debentures
that it will duly and punctually pay the principal of (and premium, if any, on)
and interest on the Debentures in accordance with the terms of the Debentures
and this Indenture.

          All payments of principal, premium, if any, and interest will be made
by the Company in immediately available funds. The Debentures shall be included
in the Same-Day Funds Settlement System of The Depository Trust Company until
maturity.

          Section 10.2   MAINTENANCE OF OFFICE OR AGENCY.

          The Company will maintain in the Borough of Manhattan, City of New
York, State of New York, an office or agency where Debentures may be presented
or surrendered for payment (a "PLACE OF PAYMENT"), where Debentures may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Company in respect of the Debentures and this Indenture
may be served. Initially, the Company hereby designates the Corporate Trust
Office of the Trustee for all such purposes, and the Company hereby designates
the Trustee as the initial Paying Agent. The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Company shall fail to maintain any such
required office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

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

          Section 10.3   MONEY FOR DEBENTURES PAYMENTS TO BE HELD IN TRUST.

          If the Company shall at any time act as its own Paying Agent with
respect to the Debentures, it will, on or before each due date of the principal
of or any premium or interest on any of the Debentures, segregate and hold in
trust for the benefit of the Persons entitled thereto a sum sufficient to pay
the principal and any premium and 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 action or failure to act.



                                       46



<PAGE>   52

          Whenever the Company shall have one or more Paying Agents for the
Debentures, it will, prior to each due date of the principal of or any premium
or interest on any Debentures, deposit with a Paying Agent, in immediately
available funds, a sum sufficient to pay such amount, such sum to be held as
provided by the Trust Indenture Act, and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of its action or failure
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 10.3
that such Paying Agent will:

          (1) hold all sums held by it for the payment of principal of (and
     premium, if any) or interest on Debentures 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 Debentures) in the making of any such payment of
     principal (and premium, if any) or interest; and

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

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same 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 or any premium or
interest on any Debenture and remaining unclaimed for two years after such
principal, premium or interest has become due and payable shall be paid to the
Company on Company Request, or (if then held by the Company) shall be discharged
from such trust; and the Holder of such Debenture shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in The Wall Street Journal or The New York Times (national
edition), 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 BY OFFICERS AS TO DEFAULT.

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

          (b) When any Default has occurred and is continuing under this
Indenture, or if the trustee for or the holder of any other evidence of
Indebtedness of the Company gives notice or takes any other action with respect
to a claimed default, the Company shall deliver to the Trustee by registered or
certified mail, or by facsimile transmission, its status, and what action the
Company is taking or proposes to take in respect thereof within 30 days after a
Senior Officer of the Company becomes aware of the occurrence thereof, an
Officers' Certificate specifying such event, notice or other action.

          Section 10.5   PAYMENT OF TAXES AND OTHER CLAIMS.

          The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Company or upon the income,
profits or property of the Company, and (2) all lawful claims for labor,
materials and supplies which, if unpaid, might by law become a lien upon the
property of the Company; provided, however, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings and for which adequate
reserves (in the good faith judgment of the Board of Directors) have been made.

          Section 10.6   MAINTENANCE OF PROPERTIES.

          The Company will cause all properties owned by the Company or used or
held for use in the conduct of its business to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of the Company may
be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that
nothing in this Section 10.6 shall prevent the Company from discontinuing the
operation or maintenance of any of such properties if such discontinuance is, in
the judgment of the Board of Directors (or, in the case of real estate owned
properties, in the judgment of a Senior Officer), desirable in the conduct of
its business or the business of the Company and not disadvantageous in any
material respect to the Holders.

          The Company will do or cause to be done all things necessary to
preserve and keep in full force and effect the existence, rights (charter and
statutory) and franchises of the Company; provided, however, that any such right
or franchise of the Company may be terminated if the Board of Directors shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company and that the loss thereof is not, and is not
reasonably likely to be, disadvantageous in any material respect to the Holders.

          The Company shall keep proper books and records, in which full and
correct entries shall be made of all financial transactions and the assets,
liabilities and business of the Company, in accordance with GAAP.

          Section 12.1   DEBENTURES SUBORDINATE TO SENIOR INDEBTEDNESS.

          (a) The Company covenants and agrees, and each Holder of a Debenture,
by his acceptance thereof, likewise covenants and agrees, that, to the extent

<PAGE>   55

hereinafter set forth in this Article Twelve, the Indebtedness represented by
the Debentures and the payment of the principal of and premium (if any) and
interest on each and all of the Debentures, are hereby expressly made
subordinate and subject in right of payment to the prior payment in full of
existing and future Senior Indebtedness of the Company. If any Senior
Indebtedness is disallowed, avoided or subordinated pursuant to the provisions
of Section 548 of the Bankruptcy Code or any applicable state fraudulent
conveyance law, such Senior Indebtedness nevertheless will constitute Senior
Indebtedness for purposes of this Indenture. For purposes of this Article
Twelve, (i) a "PAYMENT" includes any payment with respect to principal of,
premium, if any, or interest on, the Debentures, including any deposit pursuant
to Article Fourteen and any repurchase, redemption, defeasance or other
retirement of any Debentures, and (ii) "PRINCIPAL", if used with respect to the
Debentures, shall include, without limitation, the principal portion of the
Redemption Price and Purchase Price of Debentures.

          (b) Notwithstanding anything in this Article Twelve to the contrary,
nothing herein shall apply to any payments made out of the assets of any trust
referred to in paragraph (a) of Section 14.4.

          Section 12.2   PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC.

          (a) Upon any payment or distribution of the assets of the Company to
creditors upon a total or partial liquidation or total or partial dissolution of
the Company or in a bankruptcy, reorganization, insolvency, receivership or
similar proceeding relating to the Company or its property (whether voluntary or
involuntary), (i) the holders of Senior Indebtedness of the Company shall be
entitled to receive payment in full before the holders of the Debentures are
entitled to receive any payment, and (ii) until the Senior Indebtedness of the
Company is paid in full, any payment to which the Holders of the Debentures
would be entitled but for this Section 12.2 will be made to holders of Senior
Indebtedness as their interests may appear, except that Holders may receive
shares of stock or Indebtedness of the Company that is subordinated to at least
the same extent as the Debentures.

          (b) [Intentionally omitted].

          (c) In the event that, notwithstanding the foregoing provisions of
this Section 12.2, the Trustee or the Holder of any Debenture shall have
received any payment or distribution of any kind or character, whether in cash,
securities or other property, before all Senior Indebtedness is paid in full,
then and in such event such payment or distribution shall be paid over or
delivered forthwith to the trustee in bankruptcy, receiver, liquidating trustee,
custodian, assignee, agent or other official for application to the payment of
all Senior Indebtedness remaining unpaid, to the extent necessary to pay all
Senior Indebtedness in full, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.

          Section 12.3   NO PAYMENT WHEN INDEBTEDNESS IN DEFAULT.

          (a) DEBENTURE PAYMENTS. The Company may not make any payment with
respect to the Debentures if (i) any Senior Indebtedness of the Company is not
paid when due or 



                                       50

<PAGE>   56

(ii) any other default on any such Senior Indebtedness occurs and the maturity
thereof has been accelerated in accordance with its terms, unless, in either
case, (x) the default has been cured or waived and any such acceleration has
been rescinded or (y) such Senior Indebtedness has been paid in full.

          (b) [Intentionally omitted.]

          (c) APPLICATION. The provisions of this Section 12.3 shall not apply
to any payment with respect to which Section 12.2 would be applicable.

          Section 12.4   PAYMENT PERMITTED IF NO DEFAULT.

          Nothing contained in this Article Twelve or elsewhere in this
Indenture or in any of the Debentures shall prevent (a) the Company, at any time
except during the pending of any liquidation, dissolution or proceeding referred
to in Section 12.2 or under the conditions described in Section 12.3, from
making payments at any time of principal of (or premium, if any) or interest on
the Debentures, or (b) the application by the Trustee of any money deposited
with it hereunder to the payment of or on account of the principal (and premium,
if any) or interest on the Debentures or the retention of such payment by the
Holders, if, at the time of such application by the Trustee, it did not have
knowledge that such payment would have been prohibited by the provisions of this
Article Twelve.

          Section 12.5   SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR 
                         INDEBTEDNESS.

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

          Section 12.6   PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

          The provisions of this Article Twelve are and are intended solely for
the purpose of defining the relative rights of the Holders of the Debentures and
the holders of Senior Indebtedness. Nothing contained in this Article Twelve or
elsewhere in this Indenture or in the Debentures is intended to or shall (a)
impair, as among the Company, its creditors other than holders of Indebtedness
and the Holders of the Debentures, the obligations of the Company, which are
absolute and unconditional, to pay to the Holders of the Debentures the
principal of (and premium, if any) and interest on the Debentures as and when
the same shall become due and 


                                       51



<PAGE>   57

payable in accordance with their terms; or (b) affect the relative rights
against the Company of the Holders of the Debentures and creditors of the
Company other than the holders of Senior Indebtedness; or (c) prevent the
Trustee or the Holder of any Debenture from exercising all remedies otherwise
permitted by applicable law upon an Event of Default, subject to the rights, if
any, under this Article Twelve of the holders of Senior Indebtedness to receive
cash, property and securities otherwise payable or deliverable to the Trustee or
such Holder.

          Section 12.7   TRUSTEE TO EFFECTUATE SUBORDINATION.

          Each Holder of a Debenture 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 Twelve and
appoints the Trustee his attorney-in-fact for any and all such purposes.

          Section 12.8   NO WAIVER OF SUBORDINATION PROVISIONS.

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

          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
Debentures, without incurring responsibility to the Holders of the Debentures
and any Beneficiaries and without impairing or releasing the subordination
provided in this Article Twelve or the obligations hereunder of the Holders of
the Debentures to the holders of Senior Indebtedness, do any one or more of the
following: (i) change the manner, place, amount 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 Indebtedness or any instrument evidencing the
same or any agreement under which Senior Indebtedness is outstanding; (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing Senior Indebtedness; (iii) release any Person liable in any
manner for the collection of Senior Indebtedness; and (iv) exercise or refrain
from exercising any rights against the Company and any other Person.

          Section 12.9   NOTICE TO TRUSTEE.

          The Company shall give prompt written notice to the Trustee of any
fact known to the Company which would prohibit the making of any payment to or
by the Trustee in respect of the Debentures pursuant to this Article Twelve.
Notwithstanding the provisions of this Article Twelve or any other provision of
this Indenture, the Trustee shall not be charged with knowledge of the existence
of any facts which would prohibit the making of any payment to or by the Trustee
in respect of the Debentures, unless and until the Trustee shall have received
written notice thereof from the Company or a holder of Indebtedness or from any
Representative thereof; and, 



                                       52



<PAGE>   58

prior to the receipt of any such written notice, the Trustee, subject to the
provisions of Article Six, shall be entitled in all respects to assume that no
such facts exist; provided, however, that if the Trustee shall not have received
the notice provided for in this Section 12.9 at least three Business Days prior
to the date upon which by the terms hereof any money may become payable for any
purpose (including, without limitation, the payment of the principal (and
premium, if any) or interest on any Debenture), then, anything herein contained
to the contrary notwithstanding, the Trustee shall have full power and authority
to receive such money and to apply the same to the purpose for which such money
was received and shall not be affected by any notice to the contrary which may
be received by it within three Business Days prior to such date.

          Subject to the provisions of Article Six, the Trustee shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a Representative of Senior Indebtedness to establish
that such notice has been given by a holder of Senior Indebtedness (or a trustee
therefor or other representative thereof). In the event that the Trustee
determines in good faith that further evidence is required with respect to the
right of any Person as a holder of Senior Indebtedness to participate in any
payment or distribution pursuant to this Article Twelve, 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 Twelve,
and if such evidence is not furnished, the Trustee may defer any payment to such
Person pending judicial determination as to the right of such Person to receive
such payment or distribution.

          Section 12.10  RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF 
                         LIQUIDATING AGENT.

          Upon any payment or distribution of assets of the Company referred to
in this Article Twelve, the Trustee, subject to the provisions of Article Six,
and the Holders of the Debentures shall be entitled to rely upon any order or
decree entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Debentures, for the purpose of
ascertaining the Person entitled to participate in such payment or distribution,
the holders of the Senior Indebtedness and other indebtedness of the Company,
the amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article Twelve.

          Section 12.11  TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR 
                         INDEBTEDNESS.

          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 Debentures
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
Twelve or otherwise.

          Section 12.12  RIGHTS OF TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS.

          The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article Twelve with respect to any Senior Indebtedness
that 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 Twelve shall apply to claims of, or payments
to, the Trustee pursuant to Section 6.7.

          Section 12.13  ARTICLE APPLICABLE TO PAYING AGENTS.

          In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "TRUSTEE"
as used in this Article Twelve 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 Twelve in addition to or in place of Trustee; provided,
however, that Section 12.12 shall not apply to the Company or any Affiliate of
the Company if it or such Affiliate acts as Paying Agent.

          Notice of redemption having been given as aforesaid, the Debentures so
to be redeemed shall, on the Redemption Date, become due and payable at the

Company shall default in the payment of the Redemption Price and accrued
interest) such Debentures shall cease to bear interest. Upon surrender of any
such Debenture for redemption in accordance with said notice, such Debenture
shall be paid by the Company at the Redemption Price, together with accrued but
unpaid interest to the Redemption Date; provided, however, that, installments of
interest whose stated maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Debentures, or one or more Predecessor
Debentures, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 3.8.

the Trustee shall authenticate and deliver to the Holder of such Debenture
without service charge, a new Debenture or Debentures of like tenor, of any
authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Debenture so surrendered.

acknowledging the same), except for the following provisions, which shall
survive until otherwise terminated or discharged hereunder: (a) the rights of
Holders of Outstanding Debentures to receive solely from the trust fund

     trust, for the benefit of the Holders, unencumbered cash in United States
     dollars, unencumbered U.S. Government Obligations, or a combination
     thereof, in such amounts as will be sufficient, in a written opinion of a
     nationally recognized firm of independent public accountants delivered to
     the Trustee, to pay the principal of, premium, if any, and interest on the
     outstanding Debentures on the stated date for payment thereof or on the
     applicable Redemption Date, as the case may be, and the Company must
     specify whether the Debentures are being defeased to maturity or to a
     particular Redemption Date, and (ii) irrevocably instruct the Trustee to

     reasonably acceptable to the Trustee confirming that (A) the Company has
     received from, or there has been published by, the Internal Revenue Service
     a ruling or (B) since the date of this Indenture, there has been a change
     in the applicable federal income tax law, in either case to the effect
     that, and based thereon such Opinion of Counsel shall confirm that, the
     Holders of the Outstanding Debentures will not recognize income, gain or
     loss for federal income tax purposes as a result of such Legal Defeasance
     and will be subject to federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if such Legal
     Defeasance had not occurred;

     continuing on (i) the date of such deposit (other than a Default or Event
     of Default resulting from the Incurrence of Indebtedness all or a portion
     of the proceeds of which will be used to defease the Debentures pursuant to
     this Article Fourteen concurrently with such Incurrence) and (ii) insofar
     as Section 5.1(g) hereof is concerned, at any time during the period ending
     on the 91st day after the date of deposit (such condition not being
     satisfied until such 91st day);

          (d) such Legal Defeasance shall not result in a breach or violation

     generally;

          (f) the Company shall have delivered to the Trustee an Officers'
     Certificate stating that the deposit was not made by the Company with the
     intent of preferring the Holders over any other creditors of the Company or
     with the intent of defeating, hindering, delaying or defrauding any other
     creditors of the Company; and

          (g) the Company shall have delivered to the Trustee Officers'
     Certificates and an Opinion of Counsel, each stating that all conditions
     precedent provided for or relating to the Legal Defeasance have been
     complied with.

          Section 14.5   DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE 
                         HELD IN TRUST; OTHER MISCELLANEOUS PROVISIONS.

          Subject to Section 14.6, all money and U.S. Government Obligations
(including the proceeds thereof) deposited with the Trustee (or other qualifying
trustee, collectively for purposes of this Section 14.5, the "TRUSTEE") pursuant
to Section 14.4 in respect of the Outstanding Debentures shall be held in trust
and applied by the Trustee, in accordance with the provisions of the Debentures
and this Indenture, to the payment, either directly or through any Paying Agent
(excluding the Company acting as Paying Agent) as the Trustee may determine, to
the Holders of such Debentures of all sums due and to become due thereon in
respect of principal, premium, if any, and interest, but such money need not be
segregated from other funds except to the extent required by law.

          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the cash or U.S. Government
Obligations deposited pursuant to Section 14.4 or the principal and interest
received in respect thereof.

          Anything in this Article Fourteen to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon the request
of the Company any money or U.S. Government Obligations held by it as provided
in Section 14.4 which, in the opinion of a

nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee (which may be the opinion
delivered under Section 14.4), are in excess of the amount thereof that would
then be required to be deposited to effect an equivalent Legal Defeasance or
Covenant Defeasance.

          Section 14.6   REPAYMENT TO COMPANY.

          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, premium, if any,
or interest on any Debenture and remaining unclaimed for two years after such
principal, and premium, if any, or interest has become due and payable shall be
paid to the Company on its request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Debenture shall thereafter,
as a creditor, look only to the Company for payment thereof, and all liability
of the Trustee or such Paying Agent with respect to such trust money, and all
liability of the Company as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make
any such repayment, may at the expense of the Company cause to be published
once, in The New York Times and The Wall Street Journal (national edition),
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 notification
or publication, any unclaimed balance of such money then remaining will be
repaid to the Company.

          Section 14.7   REINSTATEMENT.

          If the Trustee or Paying Agent is unable to apply any United States
Dollars or U.S. Government Obligations in accordance with Section 14.2 or 14.3,
as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture, the Debentures
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 14.2 or 14.3 until such time as the Trustee or Paying Agent is permitted
to apply all such money in accordance with Section 14.2 or 14.3, as the case may
be; provided, however, that, if the Company makes any payment of principal of,
premium, if any, or interest on any Debenture following the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of
such Debentures to receive such payment from the money held by the Trustee or
Paying Agent.

                                 ARTICLE FIFTEEN

                                  MISCELLANEOUS

          Section 15.1.  NO RECOURSE AGAINST OTHERS.

          The general partner of the Company, any officer, director, employee or
agent, as such, of the general partner or of Company, shall not have any
liability for any obligations of the Company under the Debentures or this
Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation. Each Holder by accepting a Debenture waives and
releases all such liability.
