to the Trustee an Officers' Certificate stating that all conditions precedent,
if any, provided for in this Indenture (including any covenant compliance with

      certificate or opinion are based;

            (3) a statement that, in the opinion of each such individual, he has

reasonable care should know, that the certificate or opinion or representations

it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the

form one instrument.

waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agents duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes 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 conclusive in favor of the Trustee and the Company, if made in the
manner provided in this Section.

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

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

            (d) If the Company shall solicit from the Holders any request,
demand, authorization, direction, notice, consent, waiver or other Act, the
Company may, at its option, by or pursuant to a Board Resolution, fix in advance
a record date for the determination of Holders entitled to give such request,
demand, authorization, direction, notice, consent, waiver or other Act, but the
Company shall have no obligation to do so. Notwithstanding TIA Section 316(c),
such record date shall be the record date specified in or pursuant to such Board
Resolution, which shall be a date not earlier than the date 30 days prior to the
first solicitation of Holders generally in connection therewith and not later
than the date such solicitation is completed. If such a record date is fixed,
such request, demand, authorization, direction, notice, consent, waiver or other
Act may be given before or after such record date, but only the Holders of
record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Securities have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that purpose the Outstanding Securities shall be computed as of
such record date; provided that no such authorization, agreement or consent by
the Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than eleven
months after the record date.

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

                                       11


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

            (1) the Trustee by any Holder or by the Company shall be sufficient
      for every purpose hereunder if made, given, furnished or filed in writing
      to or with the Trustee at its Corporate Trust Office, Attention:
      [Corporate Trust Administration Division], 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 its principal office specified in the
      first paragraph of this Indenture, or at any other address previously
      furnished in writing to the Trustee by the Company.

            SECTION 106.  Notice to Holders; Waiver.

            Where this Indenture provides for notice of any event to Holders by
the Company or the Trustee, such notice shall be sufficiently given (unless
otherwise herein expressly provided) if in writing and mailed, first-class
postage prepaid, to each Holder affected by such event, at his address as it
appears in the Security Register, not later than the latest date, and not
earlier than the earliest date, prescribed for the giving of such notice. 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. Any notice mailed to a
Holder in the manner herein prescribed shall be conclusively deemed to have been
received by such Holder, whether or not such Holder actually receives such
notice. Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

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

            SECTION 107.  Effect of Headings and Table of Contents.

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

            SECTION 108.  Successors and Assigns.

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

            SECTION 109.  Separability Clause.

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

            SECTION 110.  Benefits of Indenture.

            Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person, other than the parties hereto, any Paying Agent, any
Securities Registrar and their successors hereunder and the Holders, any benefit
or any legal or equitable right, remedy or claim under this Indenture.

            SECTION 111.  Governing Law.

            This Indenture and the Securities shall be governed by and construed
in accordance with the law of the State of New York. This Indenture is subject
to the provisions of the Trust Indenture Act that are required to be part of
this Indenture and shall, to the extent applicable, be governed by such
provisions.

            SECTION 112.  Legal Holidays.

            In any case where any Interest Payment Date or Stated Maturity or
Maturity of any Security shall not be a Business Day, then (notwithstanding any
other provision of this Indenture or of the Securities) payment of principal or
interest need not be made on such date, but may be made on the next succeeding
Business Day with the same force and effect as if made on the Interest Payment
Date, or at the Stated Maturity or Maturity; provided that no interest shall
accrue for the period from and after such Interest Payment Date or Stated
Maturity or Maturity, as the case may be.

            Borg-Warner Automotive, Inc., a Delaware corporation (herein called
the "Company", which term includes any successor Person under the Indenture
hereinafter referred to), for value received, hereby promises to pay to
_______________ or registered assigns, the principal sum of

Company referred to below, and to pay interest thereon on __________, 1997 and
semi-annually thereafter, on [date] and [date] in each year, from __________,
1997, or from the most recent Interest Payment Date to which interest has been
paid or duly provided for, at the rate of ___% per annum, until the principal
hereof is paid or duly provided for, and (to the extent lawful) to pay on demand
interest on any overdue interest at the rate borne by the Securities from the
date on which such overdue interest becomes payable to the date payment of such
interest has been made or duly provided for. The interest so payable, and
punctually paid or duly provided for, on any Interest Payment Date will, as
provided in such Indenture, be paid to the Person in whose name this Security
(or one or more Predecessor Securities) is registered at the close of business

prior to such Special Record Date, or may be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities may be listed, and upon such notice as may be required
by such exchange, all as more fully provided in said Indenture. Payment of the
principal of and interest on this Security will be made at the office or agency
of the Company maintained for that purpose in The City of New York, or at such
other office or agency of the Company as may be maintained for such purpose, in
such coin or currency of the United States of America as at the time of payment
is legal tender for payment of public and private debts; provided, however, that
payment of interest may be made at the option of the Company (i) by check mailed
to the address of the Person entitled thereto as such address shall appear on
the Security Register or (ii) by transfer to an account maintained by the payee
located in the United States.

            Reference is hereby made to the further provisions of this Security
set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

            SECTION 203.  Form of Reverse of Security.

            This Security is one of a duly authorized issue of securities of the
Company designated as its ___% Senior Notes due 2006 (herein called the
"Securities"), limited (except as otherwise provided in the Indenture referred
to below) in aggregate principal amount to $150,000,000, which may be issued
under an indenture (herein called the
<PAGE>   22
                                       15


"Indenture") dated as of ____________, 1996 between the Company and The First
National Bank of Chicago, 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, obligations and immunities
thereunder of the Company, the Trustee and the Holders of the Securities, and of
the terms upon which the Securities are, and are to be, authenticated and
delivered.

            If an Event of Default shall occur and be continuing, the principal
of all the Securities may be declared due and payable in the manner and with the
effect provided in the Indenture.

            The Indenture contains provisions for defeasance at any time of (a)
the entire indebtedness of the Company on this Security and (b) certain
restrictive covenants and the related Defaults and Events of Default, upon
compliance by the Company with certain conditions set forth therein, which
provisions apply to this Security.

            The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of a majority in
aggregate principal amount of the Securities at the time Outstanding. The
Indenture also contains provisions permitting the Holders of specified
percentages in aggregate principal amount of the Securities at the time
Outstanding, on behalf of the Holders of all the Securities, to waive compliance
by the Company with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences. Any such consent or waiver
by or on behalf of the Holder of this Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Security and of any
Security 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 Security.

            No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and
interest on this Security at the times, place, and rate, and in the coin or
currency, herein prescribed.

            As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registerable on the Security
Register of the Company, upon surrender of this Security for registration of
transfer at the office or agency of the Company maintained for such purpose in
The City of New York, duly endorsed by, or accompanied by a written instrument
of transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
<PAGE>   23
                                       16


thereupon one or more new Securities, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.

            The Securities are issuable only in registered form without coupons
in denominations of $1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, the Securities
are exchangeable for a like aggregate principal amount of Securities of a
different authorized denomination, as requested by the Holder surrendering the
same.

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

            Prior to the time of due presentment of this Security for
registration of transfer, the Company, the Trustee and any agent of the Company
or the Trustee may treat the Person in whose name this Security is registered as
the owner hereof for all purposes, whether or not this Security be overdue, and
neither the Company, the Trustee nor any agent shall be affected by notice to
the contrary.

            All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

            SECTION 204.  Form of Trustee's Certificate of Authentication.

            The Trustee's certificate of authentication shall be in
substantially the following form:

<PAGE>   24
                                       17


            (a) If so specified in the Company Order referred to in Section 303,
the Securities may be issued in the form of one or more permanent global
Securities, registered in the name of a securities depository (the "Depository")
or its nominee, representing all the Outstanding Securities. Such global
Securities shall be substantially in the form set forth in Section 201 with such
modifications as may be necessary or desirable to reflect the issuance thereof
in global form.

            (b) Subject to the provisions of Section 303 and, if applicable,
Section 304, the Trustee shall deliver and redeliver any Security in permanent
global form in the manner and upon instructions given by the Person or Persons
specified therein or in the applicable Company Order. If a Company Order
pursuant to Section 303 or Section 304 has been, or simultaneously is,
delivered, any instructions by the Company with respect to endorsement or
delivery or redelivery of a Security in global form shall be in writing but need
not comply with Section 102 and need not be accompanied by an Opinion of
Counsel.

            (c) Notwithstanding the provisions of Section 307, payment of
principal of and interest on any Security in permanent global form shall be made
to the Person or Persons specified therein. Notwithstanding the provisions of
Section 309 and except as provided in the preceding sentence, the Company, the
Trustee and any agent of the Company and the Trustee shall treat the Holder of
any permanent global Security as the owner of such Security for the purpose of
receiving payment of principal of and (subject to Sections 305 and 307) interest
on such Security and for all other purposes whatsoever, whether or not such
Security be overdue, and none of the Company, the Trustee or any agent of the
Company or the Trustee shall be affected by notice to the contrary.

      (d) If at any time, (i) the Depository notifies the Company that it is
unwilling or unable to continue as Depository or if at any time the Depository
shall no longer be registered or in good standing under the Exchange Act, or
other applicable statute or regulation and a successor Depository is not
appointed by the Company within 90 days after the Company receives such notice
or becomes aware of such condition, as the case may be, or (ii) the Company
determines that the Securities shall no longer be represented by a global
Security or Securities and that the provisions of this Section 205 shall no
longer apply to the Securities, then in such event this Section 205 shall no
longer be applicable to the Securities and the Company will execute and the
Trustee, upon Company Request, will authenticate and deliver Securities in
definitive registered form, in authorized denominations, and in an aggregate
principal amount equal to the principal amount of the global Security or
Securities in exchange for such global Security whereupon the global Security or
Securities shall be cancelled by the Trustee. Such Securities in definitive
registered form issued in exchange for the global Security or Securities
pursuant to this Section 205(d) shall be registered in such names and issued in
such authorized denominations as the Depository, pursuant to instructions from
its direct or indirect participants or otherwise, shall instruct the Trustee.
<PAGE>   25
                                       18


The Trustee shall deliver such Securities to the Persons in whose names such
Securities are so registered.


                                  ARTICLE THREE

                                 THE SECURITIES

            SECTION 301.  Title and Terms.

            The aggregate principal amount of Securities which may be
authenticated and delivered under this Indenture is limited to $150,000,000,
except for Securities authenticated and delivered upon registration of transfer
of, or in exchange for, or in lieu of, other Securities pursuant to Section 205,
304, 305, 306 or 906.

            The Securities shall not be redeemable prior to Maturity and shall
be known and designated as the "___% Senior Notes due 2006" of the Company.
Their Stated Maturity shall be __________, 2006, and they shall bear interest at
the rate of ___% per annum from __________, 1997, or from the most recent
Interest Payment Date to which interest has been paid or duly provided for,
payable on __________, 1997 and semi-annually thereafter on [date] and [date] in
each year and at said Stated Maturity, until the principal thereof is paid or
duly provided for.

            The principal of and interest on the Securities shall be payable at
the office or agency of the Company maintained for such purpose in The City of
New York, or at such other office or agency of the Company as may be maintained
for such purpose; provided, however, that, at the option of the Company,
interest may be paid by check mailed to addresses of the Persons entitled
thereto as such addresses shall appear on the Security Register.

            SECTION 302.  Denominations.

            The Securities shall be issuable only in fully registered form
without interest coupons and only in denominations of $1,000 and any integral
multiple thereof.

            SECTION 303.  Execution, Authentication, Delivery and Dating.

            The Securities shall be executed on behalf of the Company by its
Chairman, its President or a Vice President, under its corporate seal reproduced
thereon and attested by its Secretary or an Assistant Secretary. The signature
of any of these officers on the Securities may be manual or facsimile signatures
of the present or any future such authorized officer and may be imprinted or
otherwise reproduced on the Securities. The seal of the
<PAGE>   26
                                       19


Company may be in the form of a facsimile thereof and may be impressed, affixed,
imprinted or otherwise reproduced on the Securities.

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

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

            Each Security shall be dated the date of its authentication.

            No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for in Exhibit
A, duly executed by the Trustee by manual signature of an authorized officer,
and such certificate upon any Security shall be conclusive evidence, and the
only evidence, that such Security has been duly authenticated and delivered
hereunder and is entitled to the benefits of this Indenture.

            SECTION 304.  Temporary Securities.

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

            If temporary Securities are issued, the Company will cause
definitive Securities to be prepared without unreasonable delay. After the
preparation of definitive Securities, the temporary Securities shall be
exchangeable for definitive Securities upon surrender of the temporary
Securities at the office or agency of the Company designated for such purpose
pursuant to Section 1002, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Securities, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a like
principal amount of definitive Securities of authorized denominations. Until so
exchanged, the temporary
<PAGE>   27
                                       20


Securities shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities.

            SECTION 305.  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 and in any other
office or agency designated pursuant to Section 1002 being herein sometimes
referred to as the "Security Register") in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration
of Securities and of transfers of Securities. The Security Register shall be in
written form or any other form capable of being converted into written form
within a reasonable time. At all reasonable times, the Security Register shall
be open to inspection by the Trustee. The Trustee is hereby initially appointed
as security registrar (the "Security Registrar") for the purpose of registering
Securities and transfers of Securities as herein provided.

            Upon surrender for registration of transfer of any Security at the
office or agency of the Company designated pursuant to Section 1002, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee, one or more new Securities of any authorized
denomination or denominations of a like aggregate principal amount.

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

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

            Every Security presented or surrendered for registration of transfer
or for exchange shall (if so required by the Company or the Security Registrar)
be duly endorsed, or be accompanied by a written instrument of transfer, in form
satisfactory to the Company and the Security 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 Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of
<PAGE>   28
                                       21


transfer or exchange of Securities, other than exchanges pursuant to Section 304
or 906 not involving any transfer.

            SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.

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

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

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

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

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

            SECTION 307.  Payment of Interest; Interest Rights Preserved.

            Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name such Security (or one or more Predecessor Securities) is registered
at the close of business on the Regular Record Date for such interest at the
office or agency of the Company maintained for such purpose pursuant to Section 
1002; provided, however, that each installment of interest may at the Company's
option be paid by (i) mailing a check for such interest, payable to or
<PAGE>   29
                                       22


upon the written order of the Person entitled thereto pursuant to Section 308,
to the address of such Person as it appears in the Security Register or (ii)
transfer to an account located in the United States maintained by the payee.

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

            (1) The Company may elect to make payment of any Defaulted Interest
      to the Persons in whose names the Securities (or their respective
      Predecessor Securities) are registered at the close of business on a
      Special Record Date for the payment of such Defaulted Interest, which
      shall be fixed in the following manner. The Company shall notify the
      Trustee in writing of the amount of Defaulted Interest proposed to be paid
      on each Security and the date of the proposed payment, and at the same
      time the Company shall deposit with the Trustee an amount of money equal
      to the aggregate amount proposed to be paid in respect of such Defaulted
      Interest or shall make arrangements satisfactory to the Trustee for such
      deposit prior to the date of the proposed payment, such money when
      deposited to be held in trust for the benefit of the Persons entitled to
      such Defaulted Interest as in this clause provided. Thereupon the Trustee
      shall fix a Special Record Date for the payment of such Defaulted Interest
      which shall be not more than 15 days and not less than 10 days prior to
      the date of the proposed payment and not less than 10 days after the
      receipt by the Trustee of the notice of the proposed payment. The Trustee
      shall promptly notify the Company of such Special Record Date, and in the
      name and at the expense of the Company, shall cause notice of the proposed
      payment of such Defaulted Interest and the Special Record Date therefor to
      be given in the manner provided for in Section 106, 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
      given, such Defaulted Interest shall be paid to the Persons in whose names
      the Securities (or their respective Predecessor Securities) are registered
      at the close of business on such Special Record Date and shall no longer
      be payable pursuant to the following clause (2).

            (2) The Company may make payment of any Defaulted Interest in any
      other lawful manner not inconsistent with the requirements of any
      securities exchange on which the Securities may be listed, and upon such
      notice as may be required by such exchange, if, after notice given by the
      Company to the Trustee of the proposed
<PAGE>   30
                                       23


      payment pursuant to this clause, such manner of payment shall be deemed
      practicable by the Trustee.

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

            SECTION 308.  Persons Deemed Owners.

            Prior to the due presentment of a Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Security is registered as the owner of
such Security for the purpose of receiving payment of principal of and (subject
to Sections 305 and 307) interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue, and none of the Company,
the Trustee or any agent of the Company or the Trustee shall be affected by
notice to the contrary.

            SECTION 309.  Cancellation.

            All Securities surrendered for payment, registration of transfer or
exchange shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee and shall be promptly cancelled by it. The Company may
at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and may deliver to the Trustee (or to any other Person for
delivery to the Trustee) for cancellation of any Securities previously
authenticated hereunder which the Company has not issued and sold, and all
Securities so delivered shall be promptly cancelled by the Trustee. If the
Company shall so acquire any of the Securities, however, such acquisition shall
not operate as a redemption or satisfaction of the indebtedness represented by
such Securities unless and until the same are surrendered to the Trustee for
cancellation. No Securities shall be authenticated in lieu of or in exchange for
any Securities cancelled as provided in this Section, except as expressly
permitted by this Indenture. All cancelled Securities held by the Trustee shall
be disposed of by the Trustee in accordance with its customary procedures and
certification of their disposal shall be delivered to the Company unless by
Company Order the Company shall direct that cancelled Securities be returned to
it.

            SECTION 310.  Computation of Interest.

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

            SECTION 401.  Satisfaction and Discharge of Indenture.

            This Indenture shall upon Company Request cease to be of further
effect (except as to surviving rights of registration of transfer or exchange of
the Securities expressly provided for herein or pursuant hereto) and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture when

            (1)   either

                  (A) all Securities theretofore authenticated and delivered
            (other than (i) Securities which have been destroyed, lost or stolen
            and which have been replaced or paid as provided in Section 306 and
            (ii) Securities for which payment has theretofore been deposited in
            trust with the Trustee or any Paying Agent or segregated and held in
            trust by the Company and thereafter repaid to the Company or
            discharged from such trust, as provided in Section 1003) have been
            delivered to the Trustee for cancellation; or

                  (B) all such Securities not theretofore delivered to the
            Trustee for cancellation

                        (i) have become due and payable, or

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

            and the Company, in the case of (i) or (ii) above, has irrevocably
            deposited or caused to be deposited with the Trustee as trust funds
            in trust for such purpose an amount sufficient to pay and discharge
            the entire indebtedness on such Securities not theretofore delivered
            to the Trustee for cancellation, for principal of and interest on
            the Securities to the date of such deposit (in the case of
            Securities which have become due and payable) or to the Stated
            Maturity, together with irrevocable instructions from the Company
            directing the Trustee to apply such funds to the payment thereof at
            Maturity.

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


<PAGE>   32
                                       25


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

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

            SECTION 402.  Application of Trust Money.

            Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and interest for
whose payment such money has been deposited with the Trustee; but such money
need not be segregated from other funds except to the extent required by law.

                                    REMEDIES

            SECTION 501.  Events of Default.

            "Event of Default", wherever used herein, means any one of the

                                       26


      default or breach and requiring it to be remedied and stating that such
      notice is a "Notice of Default" hereunder;

            (4) (A) there shall have occurred one or more defaults by the
      Company or any Subsidiary in the payment of the principal of Debt (other

      stated maturity thereof, and such default or defaults shall have 
      continued after any applicable grace period and shall not have been
      cured or waived or (B) Debt (other than the Securities or Non-Recourse

      repurchased (other than by regularly scheduled required prepayment), 
      prior to the stated maturity thereof and such acceleration shall not 
      have been rescinded or annulled, or such indebtedness shall not have been
      discharged, within 15 days after written notice to the Company by the 
      Trustee or to the Company and the Trustee by the Holders of not less than
      25% in aggregate principal amount of the Outstanding Securities;

            (5) the entry of a decree or order by a court having jurisdiction in
      the premises adjudging the Company or any Significant Subsidiary a
      bankrupt or insolvent, or approving as properly filed a petition seeking
      reorganization, arrangement, adjustment or composition of or in respect of
      the Company or any Significant Subsidiary under the Federal Bankruptcy
      Code or any other applicable federal or state law, or appointing a

            SECTION 502.  Acceleration of Maturity; Rescission and Annulment.
<PAGE>   34
                                       27


            If an Event of Default (other than an Event of Default specified in
Section 501(5) or 501(6)) occurs and is continuing, then and in every such case
the Trustee or the Holders of not less than 25% in aggregate principal amount of
the Outstanding Securities may declare the principal amount of all the
Securities, and all accrued and unpaid interest thereon, 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, and all
accrued and unpaid interest thereon, shall become immediately due and payable.
If an Event of Default specified in Section 501(5) or 501(6) occurs and is
continuing, then the principal amount, and all accrued and unpaid interest
thereon, of all the Securities shall ipso facto 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 a declaration of acceleration has been made with
respect to the Securities and before a judgment or decree for payment of the
money due has been obtained by the Trustee as hereinafter provided in this
Article, the Holders of a majority in principal amount of the Outstanding
Securities, by written notice to the Company and the Trustee, may on behalf of
the Holders of all of the Securities 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 Outstanding Securities,

                  (B) all unpaid principal of any Outstanding Securities which
            has become due otherwise than by such declaration of acceleration,
            and interest on such unpaid principal at the rate borne by the
            Securities,

                  (C) to the extent that payment of such interest is lawful,
            interest on overdue interest at the rate borne by the Securities,
            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, other than the non-payment of amounts of
      principal of or interest on Securities which have become due solely by
      such declaration of acceleration, have been cured or waived as provided in
      Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.
<PAGE>   35
                                       28


            Notwithstanding the preceding paragraph, in the event of a
declaration of acceleration in respect of the Securities because of an Event of
Default specified in Section 501(4) shall have occurred and be continuing, such
declaration of acceleration shall be automatically annulled if the Debt that is
the subject of such Event of Default has been discharged or the holders thereof
have rescinded their declaration of acceleration in respect of such Debt, and
written notice of such discharge or rescission, as the case may be, shall have
been given to the Trustee by the Company and countersigned by the holders of
such Debt or a trustee, fiduciary or agent for such holders, within 30 days
after such declaration of acceleration in respect of the Securities, and no
other Event of Default has occurred during such 30-day period which has not been
cured or waived during such period.

            SECTION 503. Collection of Indebtedness and Suits for Enforcement by
Trustee.

            The Company covenants that if

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

            (b) default is made in the payment of the principal of any Security
      at the Maturity thereof,

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

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

            If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and
<PAGE>   36
                                       29


enforce any such rights, whether for the specific enforcement of any covenant or
agreement in this Indenture or in aid of the exercise of any power granted
herein, or to enforce any other proper remedy.

            SECTION 504.  Trustee May File Proofs of Claim.

            In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise,

            (i) to file and prove a claim for the whole amount of principal and
      interest owing and unpaid in respect of the Securities and to file such
      other papers or documents as may be necessary or advisable in order to
      have the claims of the Trustee (including any claim for the reasonable
      compensation, expenses, disbursements and advances of the Trustee, its
      agents and counsel) and of the Holders allowed in such judicial
      proceeding, and

            (ii)  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
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 the
Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 606.

            Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

            SECTION 505.  Trustee May Enforce Claims Without Possession of
Securities.
<PAGE>   37
                                       30


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

            SECTION 506.  Application of Money Collected.

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

            FIRST: To the payment of all amounts due the Trustee under Section 
      606;

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

            THIRD: The balance, if any, to the Person or Persons entitled
      thereto, including the Company.

            SECTION 507.  Limitation on Suits.

            No Holder of Securities 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;

            (2) the Holders of not less than 25% in principal amount of the
      Outstanding Securities 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;
<PAGE>   38
                                       31


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

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

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

it being understood and intended that no one or more 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 Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and proportionate benefit of all the Holders.

            SECTION 508. Unconditional Right of Holders to Receive Principal and
Interest.

            Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment, as provided herein (including, if applicable, Article Eleven)
and in such Security, of the principal of and (subject to Section 307) interest
on, such Security on the Stated Maturity expressed therein and to institute suit
for the enforcement of any such payment, and such rights shall not be impaired
without the consent of such Holder.

            SECTION 509. Restoration of Rights and Remedies.

            If the Trustee or any Holder 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 510. Rights and Remedies Cumulative.

            Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last paragraph
of Section 306, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to
<PAGE>   39
                                       32


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

            SECTION 511.  Delay or Omission Not Waiver.

            No delay or omission of the Trustee or of any Holder of any Security
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein. Every right and remedy given by this Article or by law
to the Trustee or to the Holders 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 512.  Control by Holders.

            The Holders of not less than a majority in principal amount of the
Outstanding Securities 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, 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) the Trustee need not take any action which might involve it in
      personal liability or be unjustly prejudicial to the Holders not
      consenting.

            SECTION 513.  Waiver of Past Defaults.

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

            (1) in respect of the payment of principal of or interest on any
      Security, or

            (2) in respect of a covenant or provision hereof which under Article
      Nine cannot be modified or amended without the consent of the Holder of
      each Outstanding Security affected.
<PAGE>   40
                                       33


            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 Event of Default or impair any right consequent thereon.

            SECTION 514.  Waiver of Stay or Extension Laws.

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


                                   ARTICLE SIX

            Within 90 days after the occurrence of any Default hereunder, the
Trustee shall transmit, in the manner and to the extent provided in TIA Section 
313(c), notice of such Default hereunder known to the Trustee, unless such
Default shall have been cured or waived; provided, however, that, except in the
case of a Default in the payment of the principal of or interest on any
Security, the Trustee shall be protected in withholding such notice if and so
long as the board of directors, the executive committee or a trust committee of
directors and/or Responsible Officers of the Trustee in good faith determines
that the withholding of such notice is in the interest of the Holders; and
provided further that, in the case of any Default of the character specified in
Section 501(3), no such notice to Holders shall be given until at least 60 days
after the occurrence thereof.

            SECTION 602.  Certain Rights of Trustee.

            Subject to the provisions of TIA Sections 315(a) through 315(d):

      bond, debenture, note, other evidence of
<PAGE>   41
                                       34


      indebtedness or other paper or document believed by it to be genuine and

      taking, suffering or omitting any action hereunder, the Trustee (unless
      other evidence be herein specifically prescribed) may, in the absence of
      bad faith on its part, rely upon an Officers' Certificate;

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

      omitted by it hereunder in good faith and in reliance thereon;

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

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

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

            (8) the Trustee shall not be liable for any action taken, suffered
      or omitted by it in good faith and believed by it to be authorized or
      within the discretion or rights or powers conferred upon it by this
      Indenture.
<PAGE>   42
                                       35


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

            SECTION 603.  Trustee Not Responsible for Recitals or Issuance of
Securities.

            The recitals contained herein and in the Securities, except for the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and the Trustee assumes no responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities, except that the Trustee represents that it is
duly authorized to execute and deliver this Indenture, authenticate the
Securities and perform its obligations hereunder and that the statements made by
it in a Statement of Eligibility on Form T-1 supplied to the Company are true
and accurate, subject to the qualifications set forth therein. The Trustee shall
not be accountable for the use or application by the Company of Securities or
the proceeds thereof.

            SECTION 604.  May Hold Securities.

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

            SECTION 605.  Money Held in Trust.

            All moneys received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were received,

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 606.  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);
<PAGE>   43
                                       36


            (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; and

            (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 this trust, including the costs and expenses of
      defending itself against any claim or liability in connection with the
      exercise or performance of any of its powers or duties hereunder.

            The obligations of the Company under this Section to compensate the
Trustee, to pay or reimburse the Trustee for expenses, disbursements and
advances and to indemnify and hold harmless the Trustee shall constitute
additional indebtedness hereunder and shall survive the satisfaction and
discharge of this Indenture. As security for the performance of such obligations
of the Company, the Trustee shall have a claim prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of or interest on particular Securities.

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

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

            SECTION 607.  Corporate Trustee Required; Eligibility.

eligible to act as Trustee under TIA Section 310(a)(1) and shall have a combined
capital and surplus of at least $50,000,000. If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of Federal, State, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section , the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section , it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

            SECTION 608.  Resignation and Removal; Appointment of Successor.
<PAGE>   44
                                       37


            (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 609.

            (b) The Trustee may resign at any time by giving written notice
thereof to the Company. If the instrument of acceptance by a successor Trustee
required by Section 609 shall not have been delivered to the Trustee within 30
days after the giving of such notice of resignation, the resigning Trustee may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

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

            (d) If at any time:

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

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

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

then, in any such case, (i) the Company, by a Board Resolution, may remove the
Trustee, or (ii) subject to TIA Section 315(e), any Holder who has been a bona
fide Holder of a Security for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor Trustee.

            (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, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee. If,
within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities
delivered to the Company and the retiring Trustee, the successor Trustee so
<PAGE>   45
                                       38


appointed shall, forthwith upon its acceptance of such appointment, become the
successor Trustee and supersede the successor Trustee appointed by the Company.
If no successor Trustee shall have been so appointed by the Company or the
Holders and accepted appointment in the manner hereinafter provided, any Holder
who has been a bona fide Holder of a Security for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee.

            (f) The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee to the
Holders of Securities in the manner provided for in Section 106. Each notice
shall include the name of the successor Trustee and the address of its Corporate
Trust Office.

            SECTION 609.  Acceptance of Appointment by Successor.

            Every successor Trustee appointed hereunder 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 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. 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.

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

            SECTION 610.  Merger, Conversion, Consolidation or Succession to
Business.

            Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such
<PAGE>   46
                                       39


authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities. In case any of the Securities shall not have been
authenticated by such predecessor Trustee, any successor Trustee may
authenticate such Securities either in the name of any predecessor hereunder or
in the name of the successor Trustee. In all such cases such certificates shall
have the full force and effect that this Indenture provides for the certificate
of authentication of the Trustee; provided, however, that the right to adopt the
certificate of authentication of any predecessor Trustee or to authenticate
Securities in the name of any predecessor Trustee shall apply only to its
successor or successors by merger, conversion or consolidation.

into any other corporation or any conveyance, transfer or lease of all or
substantially all of the properties and assets of the Company, on a consolidated
basis, to any Person in accordance with Section 801, the successor Person formed
by such consolidation or into which the Company is merged or to which such
conveyance, transfer or lease is made shall succeed to, and be substituted for,
and may exercise every right and power of, the Company under this Indenture with
the same effect as if such successor Person had been named as the Company
herein, and in the event of any such conveyance or transfer, the Company (which
term shall for this purpose mean the Person named as the "Company" in the first
paragraph of this Indenture or any successor Person which shall theretofore
become such in the manner described in Section 801), except in the case of a
lease, shall be discharged of all obligations and covenants under this Indenture
and the Securities and may be dissolved and liquidated.

            SECTION 803.  Securities to Be Secured in Certain Events.

            If, upon any such consolidation of the Company with or merger of the
Company into any other corporation, or upon any conveyance, lease or transfer of
all or substantially all of the properties or assets of the Company, on a
consolidated basis, to any other Person, or any Principal Property of the
Company or of any Significant Subsidiary, would thereupon become subject to any
Lien, then unless such Lien could be created pursuant to Section 1008 without
equally and ratably securing the Securities, the Company or any Significant
Subsidiary, prior to or simultaneously with such consolidation, merger,
conveyance, lease or transfer, will, as to such Principal Property, secure the
Outstanding Securities hereunder (together with, if the Company shall so
determine, any other Debt of the

                                       42


Company now existing or hereafter created which is not subordinate to the
Securities) equally and ratably with (or prior to) the Debt which upon such
consolidation, merger, conveyance, lease or transfer is to become secured as to
such Principal Property by such Lien, or will cause such Securities to be so
secured.

            It shall not be necessary for any Act of Holders under this Section

            SECTION 903. Authorization and Execution of Supplemental Indentures.

            In executing, or accepting the additional trusts created by, any

<PAGE>   51
                                       44


indentures, except that it shall not be obligated to enter into any such
supplemental indenture which adversely affects the Trustee's own rights, duties
or immunities under this Indenture or otherwise.

            SECTION 904.  Effect of Supplemental Indentures.

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

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

            SECTION 905.  Conformity with Trust Indenture Act.

            Every supplemental indenture executed pursuant to this Article shall

            SECTION 906.  Reference in Securities to Supplemental Indentures.

            Securities authenticated and delivered after the execution of any

Outstanding Securities.

            SECTION 907.  Notice of Supplemental Indentures.

            Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of Section 902, the Company

substance of such supplemental indenture.


                                   ARTICLE TEN

                                    COVENANTS

            SECTION 1001.  Payment of Principal and Interest.
<PAGE>   52
                                       45


            The Company covenants and agrees for the benefit of the Holders that
it will duly and punctually pay the principal of and interest on the Securities
in accordance with the terms of the Securities and this Indenture.

            SECTION 1002.  Maintenance of Office or Agency.

            The Company will maintain in The City of New York, an office or
agency where Securities may be presented or surrendered for payment, where
Securities may be surrendered for registration of transfer or exchange and where
notices and demands to or upon the Company in respect of the Securities and this
Indenture may be served. The Corporate Trust Office of the Trustee shall be such
office or agency of the Company, unless the Company shall designate and maintain
some other office or agency for one or more of such purposes. The Company will
give prompt written notice to the Trustee of any change in the location of any
such office or agency. If at any time the Company shall fail to maintain any
such required office or agency 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 (in or outside of The City of New York) where the Securities
may be presented or surrendered for any or all such purposes and may from time
to time rescind any such designation; 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 The City of New York for such
purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and any change in the location of any such other
office or agency.

            SECTION 1003.  Money for Security Payments to Be Held in Trust.

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

            Whenever the Company shall have one or more Paying Agents for the
Securities, it will, on or before each due date of the principal of, or interest
on, any Securities, deposit with a Paying Agent a sum sufficient to pay the
principal or interest so becoming due, such sum to be held in trust for the
benefit of the Persons entitled to such principal or interest, and (unless such
Paying Agent is the Trustee) the Company will promptly notify the Trustee of
such action or any failure so to act.
<PAGE>   53
                                       46


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

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

            (2) give the Trustee notice of any default by the Company (or any
      other obligor upon the Securities) in the making of any payment of
      principal of or interest on the Securities; 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 sums.

            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 interest on
any Security and remaining unclaimed for two years after such principal or
interest has become due and payable shall be repaid to the Company on Company
Request, or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Security 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 a
newspaper published in the English language, customarily published on each
Business Day and of general circulation in the Borough of Manhattan, The City of
New York, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

            SECTION 1004.  Statement as to Compliance.
<PAGE>   54
                                       47


            The Company will deliver to the Trustee, within 120 days after the
end of each fiscal year, a brief certificate from the principal executive
officer, principal financial officer or principal accounting officer as to his
or her knowledge of the Company's compliance with all conditions and covenants
under this Indenture. For purposes of this Section 1004, such compliance shall
be determined without regard to any period of grace or requirement of notice
under this Indenture.

            SECTION 1005.  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 material taxes, assessments and
governmental charges levied or imposed upon the Company or any Significant
Subsidiary or upon the income, profits or property of the Company or any
Significant Subsidiary and (2) all material lawful claims for labor, materials
and supplies which, if unpaid, might by law become a Lien upon any Principal
Property of the Company or any Significant Subsidiary; 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.

            SECTION 1006.  Maintenance of Principal Properties.

            The Company will cause all Principal Properties 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 shall prevent or restrict the sale,
abandonment or other disposition of any of such Principal Properties if such
action is, in the judgment of the Company, desirable in the conduct of the
business of the Company and its Subsidiaries as a whole and not disadvantageous
in any material respect to the Holders.

            SECTION 1007.  Corporate Existence.

            Subject to Article Eight, the Company will do or cause to be done
all things necessary to preserve and keep in full force and effect its corporate
existence and the rights (charter and statutory) and franchises of the Company
and any Significant Subsidiary; provided, however, that the Company shall not be
required to preserve any such right or franchise if the Company shall determine
that the preservation thereof is no longer desirable in the conduct of the
business of the Company and its Subsidiaries as a whole.

                                       48


            SECTION 1008.  Limitation on Liens.

            The Company will not, and will not permit any Subsidiary of the
Company to, issue, assume or guarantee any Debt if such Debt is secured by a
mortgage, pledge, security interest or lien (a "mortgage" or "mortgages") upon
any real or personal property of the Company or any Subsidiary of the Company or
upon any shares of stock or other stock or other equity interest or indebtedness
of any Subsidiary of the Company (whether such property, shares of stock or
other equity interest or indebtedness is now owned or hereafter acquired),
without in any such case effectively providing that the Securities shall be
secured equally and ratably with (or prior to) such Debt; provided, however,
that the foregoing restrictions shall not apply to:

            (a) Mortgages existing on the date the Securities are originally
      issued or mortgages provided for under the terms of agreements existing on
      such date;

            (b) Mortgages on Current Assets securing Current Liabilities;

            (c) Mortgages on any property acquired, constructed, altered or
      improved by the Company or any Subsidiary of the Company after the date of
      the Indenture that are created or assumed contemporaneously with or within
      one year after such acquisition (or in the case of property constructed,
      altered or improved, after the completion and commencement of commercial
      operation of such property, whichever is later) to secure or provide for
      the payment of the purchase price or cost thereof, provided that in the
      case of any such construction, alteration or improvement the mortgages
      shall not apply to any property theretofore owned by the Company or any
      Subsidiary of the Company other than (i) the property so altered or
      improved and (ii) any theretofore unimproved real property on which the
      property so constructed or altered, or the improvement, is located;

            (d) Existing mortgages on property acquired (including mortgages on
      any property acquired from a Person that is consolidated with or merged
      with or into the Company or a Subsidiary of the Company) or mortgages
      outstanding at the time any Person becomes a Subsidiary of the Company
      that are not incurred in connection with such entity becoming a Subsidiary
      of the Company;

            (e) mortgages in favor of the Company or any Subsidiary of the
      Company;

            (f) mortgages on any property (i) in favor of domestic or foreign
      governmental bodies to secure partial, progress, advance or other payments
      pursuant to any contract or statute, (ii) securing indebtedness incurred
      to finance all or any part of the purchase price or cost of constructing,
      installing or improving the property subject to such mortgages including
      mortgages to secure Debt of the pollution control
<PAGE>   56
                                       49


      or industrial revenue bond type, or (iii) securing indebtedness issued or
      guaranteed by the United States, any State, any foreign country or any
      department, agency, instrumentality or political subdivision of any such
      jurisdiction; and

            (g) any extension, renewal or replacement (or successive extensions,
      renewals or replacements), in whole or in part, of any mortgage referred
      to in the foregoing clause (a), (b), (c), (d), (e) or (f); provided,
      however, that the principal amount of Debt secured thereby shall not
      exceed the principal amount of Debt so secured at the time of such
      extension, renewal or replacement, together with the reasonable costs
      related to such extension, renewal or replacement, and that such
      extension, renewal or replacement shall be limited to all or a part of the
      property that secured the mortgage so extended, renewed or replaced (plus
      improvements on such property).

            Notwithstanding the foregoing, the Company and any Subsidiary of the
Company may, without securing the Securities, issue, assume or guarantee secured
Debt (that would otherwise be subject to the foregoing restrictions) in an
aggregate amount that, together with all other such secured Debt and the
aggregate amount of Attributable Indebtedness of the Company and its
Subsidiaries deemed to be outstanding in respect of all Sale/Leaseback
Transactions entered into pursuant to Section 1009 (excluding any such
Sale/Leaseback Transactions the proceeds of which have been applied in
accordance with clauses (2) or (3) of Section 1009), does not exceed 10% of the
Consolidated Net Worth, as shown on a consolidated balance sheet as of a date
not more than 90 days prior to the proposed transaction prepared by the Company
in accordance with generally accepted accounting principles.

            SECTION 1009.  Limitation on Sale/Leaseback Transactions.

            The Company will not, and will not permit any of its Subsidiaries
to, enter into any Sale/Leaseback Transaction with any Person (other than the
Company or a Subsidiary of the Company) unless:

            (1) At the time of entering into such Sale/Leaseback Transaction,
      the Company or such Subsidiary would be entitled to incur Debt, in a
      principal amount equal to the Attributable Indebtedness with respect to
      such Sale/Leaseback Transaction, secured by a mortgage on the property
      subject to such Sale/Leaseback Transaction, pursuant to Section 1008
      without equally and ratably securing the Securities pursuant to such
      provisions;

            (2) After the date on which Securities are first issued and within a
      period commencing six months prior to the consummation of such
      Sale/Leaseback Transaction and ending six months after the consummation
      thereof, the Company or
<PAGE>   57
                                       50


      such Subsidiary shall have expended for property used or to be used in the
      ordinary course of business of the Company or such Subsidiary (including
      amounts expended for additions, expansions, alterations, repairs and
      improvements thereto) an amount equal to all or a portion of the net
      proceeds of such Sale/Leaseback Transaction, and the Company shall have
      elected to designate such amount as a credit against such Sale/Leaseback
      Transaction (with any such amount not being so designated to be applied as
      set forth in clause (3) below); or

            (3) During the 12-month period after the effective date of such
      Sale/Leaseback Transaction, the Company shall have applied to the
      voluntary defeasance or retirement of Securities or any pari passu
      indebtedness of the Company an amount equal to the net proceeds of the
      sale or transfer of the property leased in such Sale/Leaseback
      Transaction, which amount shall not be less than the fair value of such
      property at the time of entering into such Sale/Leaseback Transaction
      (adjusted to reflect any amount expended by the Company as set forth in
      clause (2) above), less an amount equal to the principal amount of such
      Securities and pari passu indebtedness voluntarily defeased or retired by
      the Company within such 12-month period and not designated as a credit
      against any other Sale/Leaseback Transaction entered into by the Company
      or any Subsidiary of the Company during such period.

            SECTION 1010.  Waiver of Certain Covenants.

            The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Section 803 or Sections 1005 to 1009,
inclusive, if before the time for such compliance the Holders of not less than a
majority in principal amount of the Outstanding Securities, by Act of such
Holders, waive such compliance in such instance with such term, provision or
condition, but no such waiver shall extend to or affect such term, provision or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such term, provision or condition shall remain in full force
and effect.

applicable to this Section 1102, the Company shall be deemed to have paid and
discharged its obligations with respect to all Outstanding Securities on the

deemed to have paid and discharged the entire indebtedness represented by the
Outstanding Securities, which shall thereafter be deemed to be "Outstanding"
only for the purposes of Section 1105 and the other Sections of this Indenture
referred to in (A) and (B) below, and to have satisfied all its other
obligations under such Securities and this Indenture insofar as such Securities
are concerned (and the Trustee at the expense of the Company, shall execute
proper instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of Outstanding Securities to receive, solely from the trust fund
described in Section 1104 and as more fully set forth in such Section, payments
in respect of the principal of and interest on such Securities when such
payments are due, (B) the Company's obligations with respect to such Securities
under Sections 304, 305, 306, 1002 and 1003, (C) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (D) this Article Eleven.
Subject to compliance with this Article Eleven, the Company may exercise its

under Section 1103 with respect to the Securities.

            SECTION 1103.  Covenant Defeasance.

            Upon the Company's exercise under Section 1101 of the option
applicable to this Section 1103, the Company shall be released from its
obligations under Section 803 and Sections 1005 through 1007 with respect to the
Outstanding Securities on and after the date the conditions set forth below are
satisfied (hereinafter, "covenant defeasance"), and the Securities shall
thereafter be deemed to be not "Outstanding" for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
"Outstanding" for all other purposes hereunder. For this purpose, such covenant
defeasance means that, with respect to the Outstanding Securities, the Company
may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such covenant or
by reason of any reference in any such covenant to any other provision herein or
in any other document and such omission to comply shall not constitute a Default
or an Event of Default under Section 501(3), but, except as specified above, the
remainder of this Indenture and such Securities shall be unaffected thereby.

            SECTION 1104.  Conditions to Defeasance or Covenant Defeasance.

            The following shall be the conditions to application of either
Section 1102 or Section 1103 to the Outstanding Securities:

            (1) The Company shall irrevocably have deposited or caused to be
      deposited with the Trustee (or another trustee satisfying the requirements
      of Section 607 who shall agree to comply with the provisions of this
      Article Eleven applicable to it) as trust funds in trust for the purpose
      of making the following payments, specifically pledged as security for,
      and dedicated solely to, the benefit of the Holders of such Securities,
      (A) cash in United States dollars in an amount, or (B) U.S. Government
      Obligations (as defined below) which, through the scheduled payment of
      principal and interest in respect thereof in accordance with their terms,
      will provide, not later than one day before the due date of any payment,
      money in an amount, or (C) a combination thereof, sufficient, in the
      opinion of a nationally recognized firm of independent public accountants
      expressed in a written certification thereof delivered to the Trustee, to
      pay and discharge, and which shall be applied by the Trustee (or other
      qualifying trustee) to pay and discharge, the principal of and interest on
      the Outstanding Securities on the Stated Maturity of such principal or
      installment of interest applicable to the Outstanding Securities on the
      day on which such payments are due and payable in accordance with the
      terms of this Indenture and of such Securities; provided that the Trustee
      shall have been irrevocably instructed to apply such money or the proceeds
      of such U.S. Government Obligations to said payments with respect to the
      Securities. For this purpose, "U.S. Government Obligations" means
      securities that are (x) direct obligations of the United States of America
      for the timely payment of which its full faith and credit is pledged or
      (y) obligations of a Person controlled or supervised by and acting as an
      agency or instrumentality of the United States of America the timely
      payment of which is unconditionally guaranteed as a full faith and credit
      obligation by the United States of America, which, in either case, are not
      callable or redeemable at the option of the issuer thereof, and shall also
      include a depository receipt issued by a bank (as defined in Section 
      3(a)(2) of the Securities Act), as custodian with respect to any such U.S.
      Government Obligation or a specific payment of principal of or interest on
      any such U.S. Government Obligation held by such custodian for the account
      of the holder of such depository receipt, provided that (except as
      required by law) such custodian is not authorized to make any deduction
      from the amount payable to the holder of such depository receipt from any
      amount received by the custodian in respect of the U.S. Government
      Obligation or the specific payment of principal of or interest on the U.S.
      Government Obligation evidenced by such depository receipt.

            (2) In the case of an election under Section 1102, the Company shall
      have delivered to the Trustee an Opinion of Counsel stating that (x) the
      Company has
<PAGE>   60
                                       53


      received from, or there has been published by, the Internal Revenue
      Service a ruling or (y) since ___________, 1996, there has been a change
      in the applicable federal income tax law, in either case to the effect
      that, and based thereon such opinion shall confirm that, the Holders of
      the Outstanding Securities will not recognize income, gain or loss for
      federal income tax purposes as a result of such 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 defeasance had not
      occurred.

            (3) In the case of an election under Section 1103, the Company shall
      have delivered to the Trustee an Opinion of Counsel to the effect that (i)
      the Holders of the Outstanding Securities will not recognize income, gain
      or loss for federal income tax purposes as a result of such covenant
      defeasance and will be subject to federal income tax on the same amounts,
      in the same manner and at the same times as would have been the case if
      such covenant defeasance had not occurred and (ii) the defeasance trust
      will be exempt from registration under the Investment Company Act of 1940.

            (4) No Default or Event of Default with respect to the Securities
      shall have occurred and be continuing on the date of such deposit or,
      insofar as paragraphs (5) and (6) of Section 501 hereof are concerned, at
      any time during the period ending on the 91st day after the date of such
      deposit (it being understood that this condition shall not be deemed
      satisfied until the expiration of such period).

            (5) Such defeasance under Section 1102 or covenant defeasance under
      Section 1103 shall not cause the Trustee to have a conflicting interest as
      defined by the TIA with respect to any securities of the Company.

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

            (7) The Company shall have delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent provided for relating to either the defeasance under Section 
      1102 or the covenant defeasance under Section 1103 (as the case may be)
      have been complied with and that no violations under the agreements
      governing any other outstanding Debt would result.

            SECTION 1105.  Deposited Money and U.S. Government Obligations to Be
Held in Trust; Other Miscellaneous Provisions.

            Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations (including any proceeds therefrom)
deposited with the Trustee
<PAGE>   61
                                       54


(or other qualifying trustee, collectively for purposes of this Section 1105,
the "Trustee") pursuant to Section 1104 in respect of the Outstanding Securities
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Securities and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Holders of such Securities of
all sums due and to become due thereon in respect of principal and interest, but
such money need not be segregated from other funds except to the extent required
by law.

            The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1104 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the Outstanding Securities.

            Anything in this Article Eleven to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations (including any proceeds
therefrom) held by it as provided in Section 1104 which, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the
amount thereof which would then be required to be deposited to effect an
equivalent defeasance or covenant defeasance, as applicable, in accordance with
this Article.

            SECTION 1106.  Reinstatement.

            If the Trustee or any Paying Agent is unable to apply any money or
U.S. Government Obligations in accordance with Section 1105 by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the Company's obligations under
this Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to Section 1102 or 1103, as the case may be, until
such time as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 1105; provided, however, that if the Company makes any
payment of principal of or interest on any Security following the reinstatement
of its obligations, the Company shall be subrogated to the rights of the Holders
of such Securities to receive such payment from the money held by the Trustee or
Paying Agent.

No. __________                                              $_______________

            Borg-Warner Automotive, Inc., a Delaware corporation (herein called
the "Company", which term includes any successor Person under the Indenture
hereinafter referred to), for value received, hereby promises to pay to
_______________ or registered assigns, the principal sum of
_______________Dollars on __________, 2006, at the office or agency of the
Company referred to below, and to pay interest thereon on __________, 1997 and
semi-annually thereafter, on [date] and [date] in each year, from __________,
1997, or from the most recent Interest Payment Date to which interest has been
paid or duly provided for, at the rate of ___% per annum, until the principal
hereof is paid or duly provided for, and (to the extent lawful) to pay on demand
interest on any overdue interest at the rate borne by the Securities from the
date on which such overdue interest becomes payable to the date payment of such
interest has been made or duly provided for. The interest so payable, and
punctually paid or duly provided for, on any Interest Payment Date will, as
provided in such Indenture, be paid to the Person in whose name this Security
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest, which shall be the [date] or
[date] (whether or not a Business Day), as the case may be, next preceding such
Interest Payment Date. Any such interest not so punctually paid or duly provided
for shall forthwith cease to be payable to the Holder on such Regular Record
Date, and such defaulted interest, and (to the extent lawful) interest on such
defaulted interest at the rate borne by the Securities, may be paid to the
Person in whose name this Security (or one
<PAGE>   64
                                       A-2


or more Predecessor Securities) is registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Securities not less
than 10 days prior to such Special Record Date, or may be paid at any time in
any other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in said Indenture. Payment
of the principal of and interest on this Security will be made at the office or
agency of the Company maintained for that purpose in The City of New York, or at
such other office or agency of the Company as may be maintained for such
purpose, in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts; provided,
however, that payment of interest may be made at the option of the Company (i)
by check mailed to the address of the Person entitled thereto as such address
shall appear on the Security Register or (ii) by transfer to an account
maintained by the payee located in the United States.

            This Security is one of a duly authorized issue of securities of the
Company designated as its ___% Senior Notes due 2006 (herein called the
"Securities"), limited (except as otherwise provided in the Indenture referred
to below) in aggregate principal amount to $150,000,000, which may be issued
under an indenture (herein called the "Indenture") dated as of ___________, 1996
between the Company and The First National Bank of Chicago, 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, obligations and immunities thereunder of the Company, the Trustee and
the Holders of the Securities, and of the terms upon which the Securities are,
and are to be, authenticated and delivered.

            If an Event of Default shall occur and be continuing, the principal
of all the Securities may be declared due and payable in the manner and with the
effect provided in the Indenture.

            The Indenture contains provisions for defeasance at any time of (a)
the entire indebtedness of the Company on this Security and (b) certain
restrictive covenants and the related Defaults and Events of Default, upon
compliance by the Company with certain conditions set forth therein, which
provisions apply to this Security.

            The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of a majority in
aggregate principal amount of the Securities at the time Outstanding. The
Indenture also contains provisions permitting the Holders of specified
percentages in aggregate principal amount of the Securities at the time
Outstanding, on behalf
<PAGE>   65
                                       A-3


of the Holders of all the Securities, to waive compliance by the Company with
certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by or on behalf of
the Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security 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 Security.

            No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and
interest on this Security at the times, place, and rate, and in the coin or
currency, herein prescribed.

            As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registerable on the Security
Register of the Company, upon surrender of this Security for registration of
transfer at the office or agency of the Company maintained for such purpose in
The City of New York, duly endorsed by, or accompanied by a written instrument
of transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Securities, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.

            The Securities are issuable only in registered form without coupons
in denominations of $1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, the Securities
are exchangeable for a like aggregate principal amount of Securities of a
different authorized denomination, as requested by the Holder surrendering the
same.

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

            Prior to the time of due presentment of this Security for
registration of transfer, the Company, the Trustee and any agent of the Company
or the Trustee may treat the Person in whose name this Security is registered as
the owner hereof for all purposes, whether or not this Security be overdue, and
neither the Company, the Trustee nor any agent shall be affected by notice to
the contrary.

            If at any time, (i) the Depository notifies the Company that it is
unwilling or unable to continue as Depository or if at any time the Depository
shall no longer be registered or in good standing under the Securities Exchange
Act of 1934, as amended, or other applicable statute or regulation and a
successor Depository is not appointed by the
<PAGE>   66
                                       A-4


Company within 90 days after the Company receives such notice or becomes aware
of such condition, as the case may be, or (ii) the Company determines that the
Securities shall no longer be represented by a global Security or Securities,
then in such event the Company will execute and the Trustee will authenticate
and deliver Securities in definitive registered form, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of this Security in exchange for this Security. Such Securities in
definitive registered form shall be registered in such names and issued in such
authorized denominations as the Depository, pursuant to instructions from its
direct or indirect participants or otherwise, shall instruct the Trustee. The
Trustee shall deliver such Securities to the Persons in whose names such
Securities are so registered.

            All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

            Unless the certificate of authentication hereon has been duly
executed by the Trustee referred to on the reverse hereof by manual signature,
this Security shall not be entitled to any benefit under the Indenture, or be
valid or obligatory for any purpose.
