      Section 102. Compliance Certificates and Opinions.

      Except as otherwise expressly provided in this Indenture, upon any
application or request by the Company to the Trustee to take any action under
any provision of this Indenture, the Company shall furnish to the Trustee an
Officers' Certificate stating that all conditions precedent, if any, provided
for in this Indenture relating to the proposed action have been complied with
and an Opinion of Counsel stating that, in the opinion of such counsel, all such
conditions precedent, if any, have been complied with, except that in the case
of any such application or request as to which the furnishing of such documents
or any of them is specifically required by any provision of this Indenture
relating to such particular application or request, no additional certificate or

      Section 103. Form of Documents Delivered to Trustee.

      In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify

or in the exercise of reasonable care should know, that the Opinion of Counsel
with respect to the matters upon which his certificate or opinion is based is

factual matters, upon a certificate or opinion of, or representations by, an

exercise of reasonable care should know, that the certificate or opinion or
representations with respect to such matters are erroneous.

applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture or any Security, they may, but need not, be
consolidated and form one instrument.

      Section 104. Acts of Holders.

      (1)  Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by or pursuant to 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 an agent duly
appointed in writing. If, but only if, Securities of a series are issuable as
Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided in or pursuant to this Indenture to be
given or taken by Holders of Securities of such series may, alternatively, be
embodied in and evidenced by the record of Holders of Securities of such series
voting in favor thereof, either in person or by proxies duly appointed in
writing, at any meeting of Holders of Securities of such series duly called and
held in accordance with the provisions of Article Fifteen, or a combination of
such instruments and any such record. Except as herein otherwise expressly
provided, such action


                                      -11-
<PAGE>
shall become effective when such instrument or instruments or record or both, in
each case, which satisfy the required percentages in principal amount of
Outstanding Securities, are delivered to the Trustee and, where it is hereby
expressly required, to the Company. Such instrument or instruments and any such
record (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "Act" of the Holders signing such instrument or
instruments or so voting at any such meeting. Proof of execution of any such
instrument or of a writing appointing any such agent, or of the holding by any
Person of a Security, shall be sufficient for any purpose of this Indenture and
(subject to Section 315 of the Trust Indenture Act) conclusive in favor of the
Trustee and the Company and any agent of the Trustee or the Company, if made in
the manner provided in this Section. The record of any meeting of Holders of
Securities shall be proved in the manner provided in Section 1506.

      Without limiting the generality of this Section 104, unless otherwise
provided in or pursuant to this Indenture, a Holder, including a Depository that
is a Holder of a global Security, may make, give or take, by a proxy, or
proxies, duly appointed in writing, any request, demand, authorization,
direction, notice, consent, waiver or other Act provided in or pursuant to this
Indenture or the Securities to be made, given or taken by Holders, and a
Depository that is a Holder of a global Security may provide its proxy or
proxies to the beneficial owners of interests in any such global Security
through such Depository's standing instructions and customary practices.

      (2) The fact and date of the execution by any Person of any such
instrument or writing may be proved in any reasonable manner which the Trustee
deems sufficient and in accordance with such reasonable rules as the Trustee may
determine; and the Trustee may in any instance require further proof with
respect to any of the matters referred to in this Section.

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

      (4) The ownership, principal amount and serial numbers of Bearer
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, may be proved by the production of such
Bearer Securities or by a certificate executed, as depositary, by any trust
company, bank, banker or other depositary reasonably acceptable to the Company,
wherever situated, if such certificate shall be deemed by the Company and the
Trustee to be satisfactory, showing that at the date therein mentioned such
Person had on deposit with such depositary, or exhibited to it, the Bearer
Securities therein described; or such facts may be proved by the certificate or
affidavit of the Person holding such Bearer Securities, if such certificate or
affidavit is deemed by the Company and the Trustee to be satisfactory. The
Trustee and the Company may assume that such ownership of any Bearer Security
continues until (1) another certificate or affidavit bearing a later date issued
in respect of the same Bearer Security is produced, or (2) such Bearer Security
is produced to the Trustee by some other Person, or (3) such Bearer Security is
surrendered in exchange for a Registered Security, or (4) such Bearer Security
is no longer Outstanding. The ownership, principal amount and serial numbers of
Bearer Securities held by the Person so executing such instrument or writing and
the date of the commencement and the date of the termination of holding the same
may also be proved in any other manner which the Company and the Trustee deem
sufficient.

<PAGE>
      (5) If the Company shall solicit from the Holders of any Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may at its option (but is not obligated to), by
Board Resolution, fix in advance a record date for the determination of Holders
of Registered Securities entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other Act. 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
Registered Securities of record at the close of business on such record date
shall be deemed to be Holders for the purpose 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.

      (6) Any request, demand, authorization, direction, notice, consent, waiver
or other Act by 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 or suffered to be done by the Trustee, any Security Registrar, any
Paying Agent, Guarantor or the Company in reliance thereon, whether or not
notation of such Act is made upon such Security.

      Section 105. Notices, Etc. to Trustee, Company and Guarantor.

      Any request, demand, authorization, direction, notice, consent, waiver or
other 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, Guarantor or the Company shall be
      sufficient for every purpose hereunder if made, given, furnished or filed
      in writing to or with the Trustee at its Corporate Trust Office, or

            (2) the Company by the Trustee, Guarantor or 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 the attention of its Treasurer at the address of its
      principal office specified in the first paragraph of this instrument or at
      any other address previously furnished in writing to the Trustee by the
      Company, or

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

      Section 106. Notice to Holders of Securities; Waiver.

      Except as otherwise expressly provided in or pursuant to this Indenture,
where this Indenture provides for notice to Holders of Securities of any event,


                                      -13-
<PAGE>
            (1) such notice shall be sufficiently given to Holders of Registered
      Securities if in writing and mailed, first-class postage prepaid, to each
      Holder of a Registered Security 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; and

            (2) such notice shall be sufficiently given to Holders of Bearer
      Securities, if any, if published in an Authorized Newspaper in The City of
      New York and, if such Securities are then listed on any stock exchange
      outside the United States, in an Authorized Newspaper in such city as the
      Company shall advise the Trustee that such stock exchange so requires, on
      a Business Day at least twice, the first such publication to be not
      earlier than the earliest date and the second such publication not later
      than the latest date prescribed for the giving of such notice.

      In any case where notice to Holders of Registered Securities is given by
mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder of a Registered Security shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein. Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given or provided. In
the case by reason of the suspension of regular mail service or by reason of any
other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder.

      In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearers Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice mailed to
Holders of Registered Securities as provided above.

      Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders of Securities shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

      Section 107. Language of Notices.

      Any request, demand, authorization, direction, notice, consent, election
or waiver required or permitted under this Indenture shall be in the English
language, except that, if the Company so elects, any published notice may be in
an official language of the country of publication.

Section 318(c) thereof, such required provision shall control.

      Section 109. Effect of Headings and Table of Contents.

expressed or not.

of the remaining provisions shall not in any way be affected or impaired
thereby.

      Section 112. Benefits of Indenture.

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

      Section 113. Governing Law.

      This Indenture (including the Guarantee), the Securities and any Coupons
shall be governed by and construed in accordance with the laws of the State of
New York applicable to agreements made or instruments entered into and, in each
case, performed in said state.

      Section 114. Business Days.

      Unless otherwise specified in or pursuant to this Indenture or any
Securities, in any case where any Interest Payment Date, Stated Maturity or
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture, any Security or any
Coupon other than a provision in any Security or Coupon that specifically states
that such provision shall apply in lieu hereof) payment need not be made at such
Place of Payment on such date but such payment may be made on the next
succeeding day that is a Business Day at such Place of Payment with the same
force and effect as if made on the Interest Payment Date or at the Stated
Maturity or Maturity, and no interest shall accrue on the amount payable on such
date or at such time for the period from and after such Interest Payment Date,

      Section 116. Judgment Currency.

under applicable law, that (a) if for the purpose of obtaining judgment in any
court it is necessary to convert the sum due in respect of the principal of, or
premium or interest, if any, or Additional Amounts on the Securities of any
series (the "Required Currency") into a currency in which a judgment will be
rendered (the "Judgment Currency"), the rate of exchange used shall be the rate
at which in accordance with normal banking procedures the Trustee could purchase
in The City of New York the Required Currency with the Judgment Currency on the
New York Banking Day preceding the day on which a final unappealable judgment is
given and (b) its obligations under this Indenture to make payments in the
Required Currency (i) shall not be discharged or satisfied by any tender, or any
recovery pursuant to any judgment (whether or not entered in accordance with
clause (a)), in any currency other than the Required Currency, except to the
extent that such tender or recovery shall result in the actual receipt, by the
payee, of the full amount of the Required Currency expressed to be payable in
respect of such payments, (ii) shall be enforceable as an alternative or
additional cause of action for the purpose of recovering in the Required
Currency the amount, if any, by which such actual receipt shall fall short of
the full amount of the Required Currency so expressed to be payable and (iii)
shall not be affected by judgment being obtained for any other sum due under
this Indenture. For purposes of the foregoing, "New York Banking Day" means any
day except a Saturday, Sunday or a legal holiday in The City of New York or a
day on which banking institutions in The City of New York are authorized or
obligated by law, regulation or executive order to be closed.

the aggregate amount of all Outstanding Securities of such series (or such
lesser amount as is permitted by the terms thereof) from time to time endorsed
thereon and may also provide that the aggregate amount of Outstanding Securities
represented thereby may from time to time be increased or reduced to reflect

accompanied by or contained in an Officers' Certificate and need not be
accompanied by an Opinion of Counsel.

      Notwithstanding the provisions of Section 307, unless otherwise specified
in or pursuant to this Indenture or any Securities, payment of principal of, any
premium and interest on, and any Additional Amounts in respect of any Security
in temporary or permanent global form shall be made to the Person or Persons
specified therein.

      and delivered upon registration or transfer of, or in exchange for, or in
      lieu of, other Securities of such series pursuant to Section 304, 305,
      306, 905 or 1107, upon repayment in part of any Registered Security of
      such series pursuant to Article Thirteen, upon surrender in part of any
      Registered Security for conversion or exchange into Common Stock or other
      securities pursuant to its terms, or pursuant to the terms of such
      Securities);

            (3) if such Securities are to be issuable as Registered Securities,
      as Bearer Securities or alternatively as Bearer Securities and Registered
      Securities, and whether the Bearer Securities are to be issuable with
      Coupons, without Coupons or both, and any restrictions applicable to the
      offer, sale or delivery of the Bearer Securities and the terms, if any,
      upon which Bearer Securities may be exchanged for Registered Securities
      and vice versa;

            (4) if any of such Securities are to be issuable in global form,
      when any of such Securities are to be issuable in global form and (i)
      whether such Securities are to be issued in temporary or permanent global
      form or both, (ii) whether beneficial owners of interests in any such
      global Security may exchange such interests for Securities of the same
      series and of like tenor and of any authorized form and denomination, and
      the circumstances under which any such exchanges may occur, if other than
      in the manner specified in Section 305, and (iii) the name of the
      Depository, as the case may be, with respect to any global Security;

      Securities or in global form, the date as of which any such Bearer
      Security or global Security shall be dated (if other than the date of
      original issuance of the first of such Securities to be issued);


                                      -18-

      authenticated and delivered;

            (21) if any of such Securities are to be issuable in global form and
      are to be issuable in definitive form (whether upon original issue or upon

            (23) any other terms of such Securities and any deletions from or
      modifications or additions to this Indenture in respect of such

      All Securities of any one series and all Coupons, if any, appertaining to
Bearer Securities of such series shall be substantially identical except as to
Currency of payments due thereunder, denomination and the rate of interest, or
method of determining the rate of interest, if any, Maturity, and the date from
which interest, if any, shall accrue and except as may otherwise be provided by
the Company in or pursuant to the Board Resolution and set forth in the
Officers' Certificate or in any indenture or indentures supplemental hereto
pertaining to such series of Securities. The terms of the Securities of any
series may provide, without limitation, that the Securities shall be
authenticated and delivered by the Trustee on original issue from time to time
upon telephonic or written order of persons designated in the Officers'
Certificate or supplemental indenture (telephonic instructions to be promptly
confirmed in writing by such person) and that such persons are authorized to
determine, consistent with such Officers' Certificate or any applicable
supplemental indenture, such terms and conditions of the Securities of such
series as are specified in such Officers' Certificate or supplemental indenture.
All Securities of any one series need not be issued at the same time and, unless
otherwise so provided by the Company, a series may be reopened for issuances of
additional Securities of such series or to establish additional terms of such
series of Securities.

      If any of the terms of the Securities of any series shall be established
by action taken by or pursuant to a Board Resolution, the Board Resolution shall
be delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of such series.

      Section 302. Currency; Denominations.

      Unless otherwise provided in or pursuant to this Indenture, the principal
of, any premium and interest on and any Additional Amounts with respect to the
Securities shall be payable in Dollars. Unless otherwise provided in or pursuant
to this Indenture, Registered Securities denominated in Dollars shall be
issuable in registered form without Coupons in denominations of $1,000 and any
integral multiple thereof, and Bearer Securities denominated in Dollars shall be
issuable in the denomination of $5,000. Securities not denominated in Dollars
shall be issuable


                                      -21-
<PAGE>
in such denominations as are established with respect to such Securities in or
pursuant to this Indenture.

      Section 303. Execution, Authentication, Delivery and Dating.

      Securities shall be executed on behalf of the Company by any Officer.
Coupons shall be executed on behalf of the Company by any Officer or by one of
the Assistant Corporate Secretaries of the Company. The signature of any of
these officers on the Securities or any Coupons appertaining thereto may be
manual or facsimile.

      Securities and any Coupons appertaining thereto bearing the manual or
facsimile signatures of individuals who were at any time the proper Officers
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 or
Coupons.

      At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities, together with any Coupons
appertaining thereto, executed by the Company, to the Trustee for authentication
and, provided that the Board Resolution and Officers' Certificate or
supplemental indenture or indentures with respect to such Securities referred to
in Section 201 or 301 and a Company Order for the authentication and delivery of
such Securities have been delivered to the Trustee, the Trustee in accordance
with the Company Order and subject to the provisions hereof and of such
Securities shall authenticate and deliver such Securities. In authenticating
such Securities, and accepting the additional responsibilities under this
Indenture in relation to such Securities and any Coupons appertaining thereto,
the Trustee shall be entitled to receive, and (subject to Sections 315(a)
through 315(d) of the Trust Indenture Act) shall be fully protected in relying
upon,

      (1) an Opinion of Counsel to the effect that:

            (a) the form or forms and terms of such Securities and Coupons, if
      any, have been established in conformity with the provisions of this
      Indenture;

            (b) all conditions precedent to the authentication and delivery of
      such Securities and Coupons, if any, appertaining thereto have been
      complied with and that such Securities and Coupons, when completed by
      appropriate insertions, executed by a duly authorized Officer, delivered
      by a duly authorized Officer to the Trustee for authentication pursuant to
      this Indenture, and authenticated and delivered by the Trustee and issued
      by the Company in the manner and subject to any conditions specified in
      such Opinion of Counsel, will constitute valid and binding obligations of
      the Company, enforceable against the Company in accordance with their
      terms, except as enforcement thereof may be subject to or limited by
      bankruptcy, insolvency, reorganization, moratorium, arrangement,
      fraudulent conveyance, fraudulent transfer or other similar laws relating
      to or affecting creditors' rights generally, and subject to general
      principles of equity (regardless of whether enforcement is sought in a
      proceeding in equity or at law), and except further as enforcement thereof
      may be limited by (A) requirements that a claim with respect to any
      Securities denominated other than in United States dollars (or


                                      -22-
<PAGE>
      a Foreign Currency or Judgment Currency in respect of such claim) be
      converted into United States dollars at a rate of exchange prevailing on a
      date determined pursuant to applicable law or (B) governmental authority
      to limit, delay or prohibit the making of payments in Foreign Currency or
      payments outside the United States; and

            (c) this Indenture has been qualified under the Trust Indenture Act;

      and

      (2) an Officers' Certificate stating that, to the best knowledge of the
Persons executing such certificate, no event which is, or after notice or lapse
of time would become, an Event of Default with respect to any of the Securities
shall have occurred and be continuing.

      If all the Securities of any series are not to be issued at one time, it
shall not be necessary to deliver an Opinion of Counsel at the time of issuance
of each Security, but such opinion, with such modifications as counsel shall
deem appropriate, shall be delivered at or before the time of issuance of the
first Security of such series. After any such first delivery, any separate
request by the Company that the Trustee authenticate Securities of such series
for original issue will be deemed to be a certification by the Company that all
conditions precedent provided for in this Indenture relating to authentication
and delivery of such Securities continue to have been complied with.

      The Trustee shall not be required to authenticate or to cause an
Authenticating Agent to authenticate any Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee's own rights,
duties or immunities under the Securities and this Indenture or otherwise in a
manner which is not reasonably acceptable to the Trustee or if the Trustee,
being advised by counsel, determines that such action may not lawfully be taken.

      Each Registered Security shall be dated the date of its authentication.
Each Bearer Security and any Bearer Security in global form shall be dated as of
the date specified in or pursuant to this Indenture. No Security or Coupon
appertaining thereto 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 Section
202 or 612 executed by or on behalf of the Trustee or by the Authenticating
Agent by the manual signature of one of its authorized officers. Such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder. Except as permitted by Section 306 or 307, the Trustee shall not
authenticate and deliver any Bearer Security unless all Coupons appertaining
thereto then matured have been detached and cancelled.

      Section 304. Temporary Securities.

      Pending the preparation of definitive Securities, the Company may execute
and deliver to the Trustee and, upon Company Order, the Trustee shall
authenticate and deliver, in the manner provided in Section 303, temporary
Securities in lieu thereof 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, in registered form or, if authorized in or pursuant to this
Indenture, in bearer form with one or more Coupons or without


                                      -23-
<PAGE>
Coupons and with such appropriate insertions, omissions, substitutions and other
variations as the Officer executing such Securities may determine, as
conclusively evidenced by such Officer's execution of such Securities. Such
temporary Securities may be in global form.

      Except in the case of temporary Securities in global form, which shall be
exchanged in accordance with the provisions thereof, if temporary Securities are
issued, the Company shall cause definitive Securities to be prepared without
unreasonable delay. After the preparation of definitive Securities of the same
series and containing terms and provisions that are identical to those of any
temporary Securities, such temporary Securities shall be exchangeable for such
definitive Securities upon surrender of such temporary Securities at an Office
or Agency for such Securities, without charge to any Holder thereof. Upon
surrender for cancellation of any one or more temporary Securities (accompanied
by any unmatured Coupons appertaining thereto), the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of authorized denominations of the same series
and containing identical terms and provisions; provided, however, that no
definitive Bearer Security, except as provided in or pursuant to this Indenture,
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth in or pursuant to this Indenture. Unless otherwise provided in or
pursuant to this Indenture with respect to a temporary global Security, until so
exchanged the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

      Section 305. Registration, Transfer and Exchange.

      With respect to the Registered Securities of each series, if any, the
Company shall cause to be kept a register (each such register being herein
sometimes referred to as the "Security Register") at an Office or Agency for
such series in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such
series. Such Office or Agency shall be the "Security Registrar" for that series
of Securities. Unless otherwise specified in or pursuant to this Indenture or
the Securities, the Trustee shall be the initial Security Registrar for each
series of Securities. The Company shall have the right to remove and replace
from time to time the Security Registrar for any series of Securities; provided
that no such removal or replacement shall be effective until a successor
Security Registrar with respect to such series of Securities shall have been
appointed by the Company and shall have accepted such appointment. In the event
that the Trustee shall not be or shall cease to be Security Registrar with
respect to a series of Securities, it shall have the right to examine the
Security Register for such series at all reasonable times. There shall be only
one Security Register for each series of Securities.

      Upon surrender for registration of transfer of any Registered Security of
any series at any Office or Agency for such series, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Registered Securities of the same
series denominated as authorized in or pursuant to this Indenture, of a like
aggregate principal amount bearing a number not contemporaneously outstanding
and containing identical terms and provisions.


                                      -24-
<PAGE>
      At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series containing
identical terms and provisions, in any authorized denominations, and of a like
aggregate principal amount, upon surrender of the Securities to be exchanged at
any Office or Agency for such series. Whenever any Registered Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Registered Securities which the Holder making the
exchange is entitled to receive.

      If provided in or pursuant to this Indenture, with respect to Securities
of any series, at the option of the Holder, Bearer Securities of such series may
be exchanged for Registered Securities of such series containing identical
terms, denominated as authorized in or pursuant to this Indenture and in the
same aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any Office or Agency for such series, with all unmatured Coupons
and all matured Coupons in default thereto appertaining. If the Holder of a
Bearer Security is unable to produce any such unmatured Coupon or Coupons or
matured Coupon or Coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company
and the Trustee in an amount equal to the face amount of such missing Coupon or
Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that, except as otherwise provided in Section 1002, interest
represented by Coupons shall be payable only upon presentation and surrender of
those Coupons at an Office or Agency for such series located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such Office or Agency for such series in exchange for a
Registered Security of such series and like tenor after the close of business at
such Office or Agency on (i) any Regular Record Date and before the opening of
business at such Office or Agency on the relevant Interest Payment Date, or (ii)
any Special Record Date and before the opening of business at such Office or
Agency on the related date for payment of Defaulted Interest, such Bearer
Security shall be surrendered without the Coupon relating to such Interest
Payment Date or proposed date of payment, as the case may be (or, if such Coupon
is so surrendered with such Bearer Security, such Coupon shall be returned to
the Person so surrendering the Bearer Security), and interest or Defaulted
Interest, as the case may be, shall not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but shall be payable only
to the Holder of such Coupon when due in accordance with the provisions of this
Indenture.

      If provided in or pursuant to this Indenture with respect to Securities of
any series, at the option of the Holder, Registered Securities of such series
may be exchanged for Bearer Securities upon such terms and conditions as may be
provided in or pursuant to this Indenture with respect to such series.

      Whenever any Securities are surrendered for exchange as contemplated by
the immediately preceding two paragraphs, the Company shall execute, and the
Trustee shall


                                      -25-
<PAGE>
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

      Notwithstanding the foregoing, except as otherwise provided in or pursuant
to this Indenture, any global Security shall be exchangeable for definitive
Securities only if (i) the Depository is at any time unwilling, unable or
ineligible to continue as Depository and a successor depository is not appointed
by the Company within 90 days of the date the Company is so informed in writing,
(ii) the Company executes and delivers to the Trustee a Company Order to the
effect that such global Security shall be so exchangeable, or (iii) an Event of
Default has occurred and is continuing with respect to the Securities. If the
beneficial owners of interests in a global Security are entitled to exchange
such interests for definitive Securities as the result of an event described in
clause (i), (ii) or (iii) of the preceding sentence, then without unnecessary
delay but in any event not later than the earliest date on which such interests
may be so exchanged, the Company shall deliver to the Trustee definitive
Securities in such form and denominations as are required by or pursuant to this
Indenture, and of the same series, containing identical terms and in aggregate
principal amount equal to the principal amount of such global Security, executed
by the Company. On or after the earliest date on which such interests may be so
exchanged, such global Security shall be surrendered from time to time by the
Depository as shall be specified in the Company Order with respect thereto, and
in accordance with instructions given to the Trustee and the Depository (which
instructions shall be in writing but need not be contained in or accompanied by
an Officers' Certificate or be accompanied by an Opinion of Counsel), as shall
be specified in the Company Order with respect thereto to the Trustee, as the
Company's agent for such purpose, to be exchanged, in whole or in part, for
definitive Securities as described above without charge. The Trustee shall
authenticate and make available for delivery, in exchange for each portion of
such surrendered global Security, a like aggregate principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor as the portion of such global Security to be exchanged, which (unless such
Securities are not issuable both as Bearer Securities and as Registered
Securities, in which case the definitive Securities exchanged for the global
Security shall be issuable only in the form in which the Securities are
issuable, as provided in or pursuant to this Indenture) shall be in the form of
Bearer Securities or Registered Securities, or any combination thereof, as shall
be specified by the beneficial owner thereof, but subject to the satisfaction of
any certification or other requirements to the issuance of Bearer Securities;
provided, however, that no such exchanges may occur during a period beginning at
the opening of business 15 days before any selection of Securities of the same
series to be redeemed and ending on the relevant Redemption Date; and provided,
further, that (unless otherwise provided in or pursuant to this Indenture) no
Bearer Security delivered in exchange for a portion of a global Security shall
be mailed or otherwise delivered to any location in the United States. Promptly
following any such exchange in part, such global Security shall be returned by
the Trustee to such Depository or such other Depository referred to above in
accordance with the instructions of the Company referred to above. If a
Registered Security is issued in exchange for any portion of a global Security
after the close of business at the Office or Agency for such Security where such
exchange occurs on or after (i) any Regular Record Date for such Security and
before the opening of business at such Office or Agency on the next Interest
Payment Date, or (ii) any Special Record Date for such Security and before the
opening of business at such Office or Agency on the related proposed date for
payment of interest or Defaulted Interest, as the case may be, interest shall
not be payable on such Interest Payment Date or proposed date for payment, as
the case may be, in


                                      -26-
<PAGE>
respect of such Registered Security, but shall be payable on such Interest
Payment Date or proposed date for payment, as the case may be, only to the
Person to whom interest in respect of such portion of such global Security shall
be payable in accordance with the provisions of this Indenture.

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

      Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar for such Security) be duly endorsed, or be accompanied by
a written instrument of transfer in form satisfactory to the Company and the
Security Registrar for such Security 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, or redemption of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge and any other
expenses (including fees and expenses of the Trustee) that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 304, 905 or 1107, upon repayment in part of
any Registered Security pursuant to Article Thirteen, or upon surrender in part
of any Registered Security for conversion or exchange into Common Stock or other
securities pursuant to its terms, in each case not involving any transfer.

      Except as otherwise provided in or pursuant to this Indenture, the Company
shall not be required (i) to issue, register the transfer of or exchange any
Securities during a period beginning at the opening of business 15 days before
the day of the selection for redemption of Securities of like tenor and the same
series under Section 1103 and ending at the close of business on the day of such
selection, or (ii) to register the transfer of or exchange any Registered
Security so selected for redemption in whole or in part, except in the case of
any Security to be redeemed in part, the portion thereof not to be redeemed, or
(iii) to exchange any Bearer Security so selected for redemption except, to the
extent provided with respect to such Bearer Security, that such Bearer Security
may be exchanged for a Registered Security of like tenor and the same series,
provided that such Registered Security shall be immediately surrendered for
redemption with written instruction for payment consistent with the provisions
of this Indenture or (iv) to issue, register the transfer of or exchange any
Security which, in accordance with its terms, has been surrendered for repayment
at the option of the Holder, except the portion, if any, of such Security not to
be so repaid.

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

      If any mutilated Security or a Security with a mutilated Coupon
appertaining to it is surrendered to the Trustee, subject to the provisions of
this Section 306, the Company shall execute and the Trustee shall authenticate
and deliver in exchange therefor a new Security of the same series containing
identical terms and of like principal amount and bearing a number not


                                      -27-
<PAGE>
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

      If there be delivered to the Company and to the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security or Coupon,
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security or Coupon has been acquired by a
bona fide purchaser, the Company shall execute and, upon the Company's request
the Trustee shall authenticate and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Security or in exchange for the
Security to which a destroyed, lost or stolen Coupon appertains with all
appurtenant Coupons not destroyed, lost or stolen, a new Security of the same
series containing identical terms and of like principal amount and bearing a
number not contemporaneously outstanding, with Coupons corresponding to the
Coupons, if any, appertaining to such destroyed, lost or stolen Security or to
the Security to which such destroyed, lost or stolen Coupon appertains.

      Notwithstanding the foregoing provisions of this Section 306, in case any
mutilated, destroyed, lost or stolen Security or Coupon has become or is about
to become due and payable, the Company in its discretion may, instead of issuing
a new Security, pay such Security or Coupon; provided, however, that payment of
principal of, any premium or interest on or any Additional Amounts with respect
to any Bearer Securities shall, except as otherwise provided in Section 1002, be
payable only at an Office or Agency for such Securities located outside the
United States and, unless otherwise provided in or pursuant to this Indenture,
any interest on Bearer Securities and any Additional Amounts with respect to
such interest shall be payable only upon presentation and surrender of the
Coupons appertaining thereto.

      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, with any Coupons appertaining thereto issued pursuant
to this Section in lieu of any destroyed, lost or stolen Security, or in
exchange for a Security to which a destroyed, lost or stolen Coupon appertains
shall constitute a separate obligation of the Company, whether or not the
destroyed, lost or stolen Security and Coupons appertaining thereto or the
destroyed, lost or stolen Coupon shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of such series and any
Coupons, if any, duly issued hereunder.

      The provisions of this Section, as amended or supplemented pursuant to
this Indenture with respect to particular Securities or generally, shall be
exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities or Coupons.

      Section 307. Payment of Interest and Certain Additional Amounts; Rights to
Interest and Certain Additional Amounts Preserved.

      Unless otherwise provided in or pursuant to this Indenture, any interest
on and any Additional Amounts with respect to any Registered Security which
shall be payable, and are 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 as of the close of business on the
Regular Record Date for such interest. Unless otherwise provided in or pursuant
to this Indenture, in case a Bearer Security is surrendered in exchange for a
Registered Security after the close of business at an Office or Agency for such
Security on any Regular Record Date therefor and before the opening of business
at such Office or Agency on the next succeeding Interest Payment Date therefor,
such Bearer Security shall be surrendered without the Coupon relating to such
Interest Payment Date and interest shall not be payable on such Interest Payment
Date in respect of the Registered Security issued in exchange for such Bearer
Security, but shall be payable only to the Holder of such Coupon when due in
accordance with the provisions of this Indenture.

      Unless otherwise provided in or pursuant to this Indenture, any interest
on and any Additional Amounts with respect to any Registered Security which
shall be payable, but shall not be punctually paid or duly provided for, on any
Interest Payment Date for such Registered Security (herein called "Defaulted
Interest") shall forthwith cease to be payable to the Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder; and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in Clause (1) or (2) below:

            (1) The Company may elect to make payment of any Defaulted Interest
      to the Person in whose name such Registered Security (or a Predecessor
      Security thereof) shall be 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 such Registered 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 on or prior to the date of the proposed payment, such
      money when so deposited to be held in trust for the benefit of the Person
      entitled to such Defaulted Interest as in this Clause provided. Thereupon,
      the Trustee shall fix a Special Record Date for the payment of such
      Defaulted Interest which shall be not more than 15 days and not less than
      10 days prior to the date of the proposed payment and not less than 10
      days after the receipt by the Trustee of the notice of the proposed
      payment. The Trustee shall promptly notify the Company of such Special
      Record Date and, in the name and at the expense of the Company shall cause
      notice of the proposed payment of such Defaulted Interest and the Special
      Record Date therefor to be mailed, first-class postage prepaid, to the
      Holder of such Registered Security (or a Predecessor Security thereof) at
      his address as it appears in the Security Register not less than 10 days
      prior to such Special Record Date. The Trustee may, in its discretion, in
      the name and at the expense of the Company cause a similar notice to be
      published at least once in an Authorized Newspaper of general circulation
      in the Borough of Manhattan,


                                      -29-
<PAGE>
      The City of New York, but such publication shall not be a condition
      precedent to the establishment of such Special Record Date. Notice of the
      proposed payment of such Defaulted Interest and the Special Record Date
      therefor having been mailed as aforesaid, such Defaulted Interest shall be
      paid to the Person in whose name such Registered Security (or a
      Predecessor Security thereof) shall be registered at the close of business
      on such Special Record Date and shall no longer be payable pursuant to the
      following clause (2). In case a Bearer Security is surrendered at the
      Office or Agency for such Security in exchange for a Registered Security
      after the close of business at such Office or Agency on any Special Record
      Date and before the opening of business at such Office or Agency on the
      related proposed date for payment of Defaulted Interest, such Bearer
      Security shall be surrendered without the Coupon relating to such
      Defaulted Interest and Defaulted Interest shall not be payable on such
      proposed date of payment in respect of the Registered Security issued in
      exchange for such Bearer Security, but shall be payable only to the Holder
      of such Coupon when due in accordance with the provisions of this
      Indenture.

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

      Unless otherwise provided in or pursuant to this Indenture or the
Securities of any particular series, at the option of the Company, interest on
Registered Securities that bear interest may be paid by mailing a check to the
address of the Person entitled thereto as such address shall appear in the
Security Register or by transfer to an account maintained by the payee with a
bank located in the United States.

      Subject to the foregoing provisions of this Section and Section 305, 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 due presentment of a Registered Security for registration of
transfer, the Company, Guarantor, the Trustee and any agent of the Company,
Guarantor or the Trustee may treat the Person in whose name such Registered
Security is registered in the Security Register as the owner of such Registered
Security for the purpose of receiving payment of principal of, any premium and
(subject to Sections 305 and 307) interest on and any Additional Amounts with
respect to such Registered Security and for all other purposes whatsoever,
whether or not any payment with respect to such Registered Security shall be
overdue, and neither the Company, Guarantor, the Trustee or any agent of the
Company, Guarantor or the Trustee shall be affected by notice to the contrary.


                                      -30-
<PAGE>
      The Company, Guarantor, the Trustee and any agent of the Company,
Guarantor or the Trustee may treat the bearer of any Bearer Security or the
bearer of any Coupon as the absolute owner of such Security or Coupon for the
purpose of receiving payment thereof or on account thereof and for all other
purposes whatsoever, whether or not any payment with respect to such Security or
Coupon shall be overdue, and neither the Company, Guarantor, the Trustee or any
agent of the Company, Guarantor or the Trustee shall be affected by notice to
the contrary.

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

      Section 309. Cancellation.

      All Securities and Coupons surrendered for payment, redemption,
registration of transfer, exchange or conversion or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee, and any such Securities and Coupons, as well as
Securities and Coupons surrendered directly to the Trustee for any such purpose,
shall be cancelled promptly by the Trustee. The Company may at any time deliver
to the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Securities so delivered shall be cancelled promptly by the
Trustee. 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 or pursuant to this Indenture. All cancelled Securities and Coupons held by
the Trustee shall be voided and disposed of by the Trustee in accordance with
its then customary procedures and, upon the Company's request, certification of
their voidance and disposal shall be delivered to the Company, unless by a
Company Order the Company directs their return to it.

      Section 310. Computation of Interest.

      Except as otherwise provided in or pursuant to this Indenture or in the
Securities of any series, interest on the Securities shall be computed on the
basis of a 360-day year of twelve 30-day months.

                           SATISFACTION AND DISCHARGE

      Section 401. Satisfaction and Discharge.

      Upon the direction of the Company by a Company Order, this Indenture and
the Guarantee shall cease to be of further effect with respect to any series of
Securities specified in such Company Order and any Coupons appertaining thereto,
and the Trustee, on receipt of a Company Order, at the expense of the Company,
shall execute proper instruments acknowledging satisfaction and discharge of
this Indenture and the Guarantee as to such series, when

      (1)   either

            (a) all Securities of such series theretofore authenticated and
      delivered and all Coupons appertaining thereto (other than (i) Coupons
      appertaining to Bearer Securities of such series surrendered in exchange
      for Registered Securities of such series and maturing after such exchange
      whose surrender is not required or has been waived as provided in Section
      305, (ii) Securities and Coupons of such series which have been destroyed,
      lost or stolen and which have been replaced or paid as provided in Section
      306, (iii) Coupons appertaining to Securities of such series called for
      redemption and maturing after the relevant Redemption Date whose surrender
      has been waived as provided in Section 1106, and (iv) Securities and
      Coupons of such series for whose payment money has theretofore been
      deposited in trust 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 Securities of such series and, in the case of (i) or (ii)
      below, any Coupons appertaining thereto 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, or

                  (iii) if redeemable at the option of the Company, are to be
            called for redemption within one year under arrangements
            satisfactory to the Trustee for the giving of notice of redemption
            by the Trustee in the name, and at the expense, of the Company,

and the Company, in the case of (i), (ii) or (iii) above, has deposited or
caused to be deposited with the Trustee as trust funds in trust for such
purpose, money in the Currency in which such Securities are payable in an amount
sufficient to pay and discharge the entire indebtedness on such Securities and
any Coupons appertaining thereto not theretofore delivered to the Trustee for
cancellation, including the principal of, any premium and interest on, and, to
the extent that the Securities of such series provide for the payment of
Additional Amounts thereon and the amount of any such Additional Amounts is at
the time of deposit reasonably determinable by the Company (in the exercise by
the Company of its sole and absolute discretion), any Additional

                                      -32-
<PAGE>
Amounts with respect to, such Securities and any Coupons appertaining thereto,
to the date of such deposit (in the case of Securities which have become due and
payable) or to the Maturity thereof, as the case may be;

      (2) the Company has paid or caused to be paid all other sums payable
hereunder by the Company with respect to the Outstanding Securities of such
series and any Coupons appertaining thereto; and

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

      In the event there are Securities of two or more series hereunder, the
Trustee shall be required to execute an instrument acknowledging satisfaction
and discharge of this Indenture (including the Guarantee) only if requested to
do so with respect to Securities of such series as to which it is Trustee and if
the other conditions thereto are met.

      Notwithstanding the satisfaction and discharge of this Indenture
(including the Guarantee) with respect to any series of Securities, the
obligations of the Company to the Trustee under Section 607 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 Sections 305, 306, 403 and
the last paragraph of Section 1003 shall survive.

      Section 402. Defeasance and Covenant Defeasance.

      (1) Unless, pursuant to Section 301, either or both of (i) defeasance of
the Securities of or within a series under clause (2) of this Section 402 or
(ii) covenant defeasance of the Securities of or within a series under clause
(3) of this Section 402 shall not be applicable with respect to the Securities
of such series, then such provisions, together with the other provisions of this
Section 402 (with such modifications thereto as may be specified pursuant to
Section 301 with respect to any Securities), shall be applicable to such
Securities and any Coupons appertaining thereto, and the Company may at its
option by Board Resolution, at any time, with respect to such Securities and any
Coupons appertaining thereto, elect to have Section 402(2) or Section 402(3) be
applied to such Outstanding Securities and any Coupons appertaining thereto upon
compliance with the conditions set forth below in this Section 402.

      (2) Upon the Company's exercise of the above option applicable to this
Section 402(2) with respect to any Securities of or within a series, the Company
and Guarantor shall be deemed to have been discharged from their respective
obligations with respect to such Outstanding Securities and any Coupons
appertaining thereto on the date the conditions set forth in clause (4) of this
Section 402 are satisfied (hereinafter, "defeasance"). For this purpose, such
defeasance means that the Company shall be deemed to have paid and discharged
the entire indebtedness represented by such Outstanding Securities and any
Coupons appertaining thereto, which shall thereafter be deemed to be
"Outstanding" only for the purposes of clause (5) of this Section 402 and the
other Sections of this Indenture referred to in clauses (i) and (ii) below, and
to have satisfied all of its and Guarantor's other obligations under such
Securities and any Coupons appertaining thereto and this Indenture and the
Guarantee insofar as such Securities and

                                      -33-
<PAGE>
any Coupons appertaining thereto are concerned (and the Trustee, at the expense
of the Company, shall execute proper instruments acknowledging the same), except
for the following obligations of the Company which shall survive until otherwise
terminated or discharged hereunder: (i) the rights of Holders of such
Outstanding Securities and any Coupons appertaining thereto to receive, solely
from the trust fund described in clause (4) of this Section 402 and as more
fully set forth in such Section, payments in respect of the principal of (and
premium, if any) and interest, if any, on, and Additional Amounts, if any, with
respect to, such Securities and any Coupons appertaining thereto when such
payments are due, and any rights of such Holder to convert or exchange such
Securities into Common Stock or other securities, (ii) the obligations of the
Company and the Trustee with respect to such Securities under Sections 305, 306,
1002 and 1003, with respect to the payment of Additional Amounts, if any, on
such Securities as contemplated by Section 1004 (but only to the extent that the
Additional Amounts payable with respect to such Securities exceed the amount
deposited in respect of such Additional Amounts pursuant to Section 401(4)(a)
below), and with respect to any rights to convert or exchange such Securities
into Common Stock or other securities, (iii) the rights, powers, trusts, duties
and immunities of the Trustee hereunder and (iv) this Section 402. The Company
may exercise its option under this Section 402(2) notwithstanding the prior
exercise of its option under clause (3) of this Section 402 with respect to such
Securities and any Coupons appertaining thereto. Following a defeasance, payment
of the Securities of such series may not be accelerated because of an Event of
Default.

      (3) Upon the Company's exercise of the above option applicable to this
Section 402(3) with respect to any Securities of or within a series, the Company
and Guarantor shall be released from their respective obligations, if any, under
Sections 801, 1006 and any other covenants applicable to such Securities that
are determined pursuant to Section 301 to be subject to this provision with
respect to such Outstanding Securities and any Coupons appertaining thereto on
and after the date the conditions set forth in clause (4) of this Section 402
are satisfied (hereinafter, "covenant defeasance"), and such Securities and any
Coupons appertaining thereto 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 any such
covenant, but shall continue to be deemed "Outstanding" for all other purposes
hereunder. For this purpose, such covenant defeasance means that, with respect
to such Outstanding Securities and any Coupons appertaining thereto, 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 Section or such other covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such Section or such other covenant or by reason of reference in any such
Section or such other 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(4) or 501(8) or otherwise, as the case may be, but,
except as specified above, the remainder of this Indenture and such Securities
and Coupons appertaining thereto shall be unaffected thereby.

      (4) The following shall be the conditions to application of clause (2) or
(3) of this Section 402 to any Outstanding Securities of or within a series and
any Coupons appertaining thereto:

                                      -34-
<PAGE>
            (a) The Company shall irrevocably have deposited or caused to be
      deposited with the Trustee (or another trustee satisfying the requirements
      of Section 608 who shall agree to comply with the provisions of this
      Section 402 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 and any
      Coupons appertaining thereto, (1) money in an amount in Dollars or in such
      Foreign Currency in which such Securities and any Coupons appertaining
      thereto are then specified as payable at Stated Maturity, or (2)
      Government Obligations applicable to such Securities and Coupons
      appertaining thereto (determined on the basis of the Currency in which
      such Securities and Coupons appertaining thereto are then specified as
      payable at Stated Maturity) 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 of
      principal of (and premium, if any) and interest, if any, on such
      Securities and any Coupons appertaining thereto, money in an amount, or
      (3) a combination thereof in an amount, in each case, sufficient, without
      consideration of any reinvestment of such principal and interest, 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, (y) the principal of (and
      premium, if any) and interest, if any, on, and, to the extent that such
      Securities provide for the payment of Additional Amounts thereon and the
      amount of any such Additional Amounts is at the time of deposit reasonably
      determinable by the Company (in the exercise by the Company of its sole
      and absolute discretion), any Additional Amounts with respect to, such
      Outstanding Securities and any Coupons appertaining thereto on the Stated
      Maturity of such principal or installment of principal or interest and (z)
      any mandatory sinking fund payments or analogous payments applicable to
      such Outstanding Securities and any Coupons appertaining thereto on the
      day on which such payments are due and payable in accordance with the
      terms of this Indenture and of such Securities and any Coupons
      appertaining thereto.

            (b) 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.

            (c) No Event of Default or event which with notice or lapse of time
      or both would become an Event of Default with respect to such Securities
      and any Coupons appertaining thereto shall have occurred and be continuing
      (A) on the date of such deposit or (B) in so far as subsections 501(5) and
      (6) are concerned, at any time during the period ending on the 123rd day
      after the date of such deposit (it being understood that this condition
      shall not be deemed satisfied until the expiration of such period).

            (d) Such defeasance or covenant defeasance shall not (A) cause the
      Trustee for the Securities of such series to have a conflicting interest
      for purposes of the Trust Indenture Act with respect to any securities of
      the Company or (B) result in the trust arising from such deposit to
      constitute, unless it is qualified as, a regulated investment company
      under the Investment Company Act of 1940, as amended.


                                      -35-
<PAGE>
            (e) The Company shall have delivered to the Trustee an Opinion of
      Counsel to the effect that the Holders of such Outstanding Securities and
      any Coupons appertaining thereto will not recognize income, gain or loss
      for Federal income tax purposes as a result of such defeasance or covenant
      defeasance, as the case may be, 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 or covenant defeasance, as the case
      may be, had not occurred; provided that in the case of defeasance, the
      Opinion of Counsel to be delivered to the Trustee must state with respect
      to its opinion as described above that such opinion was based on either
      (A) the Company having received from, or there having been published by,
      the Internal Revenue Service a ruling, or (B) there having been a change
      in the applicable Federal income tax laws, since the date of this
      Indenture.

            (f) The Company shall have delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent to the defeasance or covenant defeasance under clause (2) or (3)
      of this Section 402 (as the case may be) have been complied with.

            (g) Notwithstanding any other provisions of this Section 402(4),
      such defeasance or covenant defeasance shall be effected in compliance
      with any additional or substitute terms, conditions or limitations which
      may be imposed on the Company in connection therewith pursuant to Section
      301.

      (5) Subject to the provisions of the last paragraph of Section 1003, all
money and Government Obligations (or other property as may be provided pursuant
to Section 301) (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 402(5) and
Section 403, the "Trustee") pursuant to clause (4) of Section 402 in respect of
any Outstanding Securities of any series and any Coupons appertaining thereto
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Securities and any Coupons appertaining thereto 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 and any Coupons appertaining
thereto of all sums due and to become due thereon in respect of principal (and
premium, if any) and interest and Additional Amounts, if any, but such money
need not be segregated from other funds except to the extent required by law.

      Unless otherwise specified in or pursuant to this Indenture or any
Securities, if, after a deposit referred to in Section 402(4)(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 402(4)(a) has been made in respect of such Security, or (b)
a Conversion Event occurs in respect of the Foreign Currency in which the
deposit pursuant to Section 402(4)(a) has been made, the indebtedness
represented by such Security and any Coupons appertaining thereto shall be
deemed to have been, and will be, fully discharged and satisfied through the
payment of the principal of (and premium, if any), and interest, if any, on, and
Additional Amounts, if any, with respect to, such Security as the same becomes
due out of the proceeds yielded by converting (from time to time as specified
below in the case of any such election) the amount or other

                                      -36-
<PAGE>
property deposited in respect of such Security into the Currency in which such
Security becomes payable as a result of such election or Conversion Event based
on (x) in the case of payments made pursuant to clause (a) above, the applicable
market exchange rate for such Currency in effect on the second Business Day
prior to each payment date, or (y) with respect to a Conversion Event, the
applicable market exchange rate for such Foreign Currency in effect (as nearly
as feasible) at the time of the Conversion Event.

      The Company shall pay and indemnify the Trustee against any tax, fee or
other charge, imposed on or assessed against the Government Obligations
deposited pursuant to this Section 402 or the principal or 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 such Outstanding Securities and any Coupons
appertaining thereto.

      Anything in this Section 402 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or Government Obligations (or other property and any proceeds therefrom)
held by it as provided in clause (4) of this Section 402 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 a
defeasance or covenant defeasance, as applicable, in accordance with this
Section 402.

      Section 403. Application of Trust Money.

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

      Section 502. Acceleration of Maturity; Rescission and Annulment.

      If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then the Trustee or the Holders of
not less than 25% in principal amount of the Outstanding Securities of such
series may declare the principal of all the Securities of such series, or such
lesser amount as may be provided for in the Securities of such series, to be due
and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by the Holders), and upon any such declaration such principal
or such lesser amount shall become immediately due and payable.

      At any time after Securities of any series have been accelerated and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter in this Article provided, the Holders of not less
than a majority in principal amount of the Outstanding Securities of such
series, by written notice to the Company and the Trustee, may rescind and annul
such declaration and its consequences if

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

            (a) all overdue installments of any interest on any Securities of
      such series and any Coupons appertaining thereto and any Additional
      Amounts with respect thereto,

            (b) the principal of and any premium on any Securities of such
      series which have become due otherwise than by such declaration of
      acceleration and any Additional Amounts with respect thereto and, to the
      extent the payment of such interest is lawful, interest thereon at the
      rate or rates borne by or provided for in such Securities,

            (c) to the extent that payment of such interest is lawful, interest
      upon overdue installments of any interest and any Additional Amounts with
      respect thereto at the rate or rates borne by or provided for in such
      Securities, and

                                      -39-
<PAGE>
            (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 all other amounts due the Trustee
      under Section 607; and

      (2) all Events of Default with respect to Securities of such series, other
than the non-payment of the principal of, any premium and interest on, and any
Additional Amounts with respect to Securities of such series which shall have
become due solely by such declaration of acceleration, shall have been cured or
waived as provided in Section 513.

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

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

      The Company covenants that if

      (1) default is made in the payment of any installment of interest on or
any Additional Amounts with respect to any Security or any Coupon appertaining
thereto when such interest or Additional Amounts shall have become due and
payable and such default continues for a period of 30 days, or

      (2) default is made in the payment of the principal of or any premium on
any Security at its Maturity, the Company shall, upon demand of the Trustee, pay
to the Trustee, for the benefit of the Holders of such Securities and any
Coupons appertaining thereto,

the whole amount of money then due and payable with respect to such Securities
and any Coupons appertaining thereto, with interest upon the overdue principal,
any premium and, to the extent that payment of such interest shall be legally
enforceable, upon any overdue installments of interest and Additional Amounts at
the rate or rates borne by or provided for in such Securities, and, in addition
thereto, such further amount of money 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 and all other
amounts due to the Trustee under Section 607.

      If the Company fails to pay the money it is required to pay the Trustee
pursuant to the preceding paragraph forthwith upon the demand of the Trustee,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the money so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company and collect the monies adjudged or decreed to be payable in
the manner provided by law out of the property of the Company, wherever
situated.

      If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series and any
Coupons appertaining thereto by such appropriate judicial proceedings as the
Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this
Indenture or such Securities or in aid of the exercise of any power granted
herein or therein, 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 the property of the Company or
its 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 any overdue principal, premium, interest or
Additional Amounts) shall be entitled and empowered, by intervention in such
proceeding or otherwise,

            (1) to file and prove a claim for the whole amount, or such lesser
      amount as may be provided for in the Securities of such series, of the
      principal and any premium, interest and Additional Amounts owing and
      unpaid in respect of the Securities and any Coupons appertaining thereto
      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 or counsel) and of the Holders of Securities or
      any Coupons allowed in such judicial proceeding, and

            (2) to collect and receive any monies or other property payable or
      deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder of Securities or any Coupons 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 of Securities or any Coupons, to pay to the Trustee any
amount due to 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 607.

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

      Section 505. Trustee may Enforce Claims Without Possession of Securities
or Coupons.

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

in case of the distribution of such money on account of principal, or any
premium, interest or Additional Amounts, upon presentation of the Securities or
Coupons, or both, as the case may be, and the notation thereon of the payment if

      kind, according to the aggregate amounts due and payable on such
      Securities and Coupons for principal and any premium, interest and
      Additional Amounts, respectively;

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

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

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

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

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

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture or any Security to affect, disturb or prejudice the rights of
any other such Holders or Holders of Securities of any other series, or to
obtain or to seek to obtain priority or preference over any other Holders or to

                                      -42-

enforce any right under this Indenture, except in the manner herein provided and
for the equal and ratable benefit of all such Holders.

      Section 508. Unconditional Right of Holders to Receive Principal and Any
Premium, Interest and Additional Amounts.

      Notwithstanding any other provision in this Indenture, the Holder of any
Security or Coupon shall have the right, which is absolute and unconditional, to
receive payment of the principal of, any premium and (subject to Sections 305
and 307) interest on, and any Additional Amounts with respect to such Security
or such Coupon, as the case may be, on the respective Stated Maturity or
Maturities therefor specified in such Security or Coupon (or, in the case of
redemption, on the Redemption Date or, in the case of repayment at the option of
such Holder if provided in or pursuant to this Indenture, on the date such
repayment is due) and to institute suit for the enforcement of any such payment,
and such right shall not be impaired without the consent of such Holder.

      Section 509. Restoration of Rights and Remedies.

      If the Trustee or any Holder of a Security or a Coupon 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 the Company, Guarantor, the Trustee and each such Holder shall, subject to
any determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee and each such Holder 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 or Coupons in the last paragraph
of Section 306, no right or remedy herein conferred upon or reserved to the
Trustee or to each and every Holder of a Security or a Coupon is intended to be
exclusive of any other right or remedy, and every right and remedy, to the
extent permitted by law, shall 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, to the extent permitted by law, 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 or
Coupon 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 any Holder of a Security or a Coupon may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by such Holder, as the case may be.

      Section 512. Control by Holders of Securities.

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

            (1) such direction shall not be in conflict with any rule of law or
      with this Indenture or with the Securities of any series and shall not
      subject the Trustee to any personal liability,

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

            (3) such direction is not unduly prejudicial to the rights of the
      other Holders of Securities of such series not joining in such action.

      Section 513. Waiver of Past Defaults.

      The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series on behalf of the Holders of all the
Securities of such series and any Coupons appertaining thereto may waive any
past default hereunder with respect to such series and its consequences, except
a default

            (1) in the payment of the principal of, any premium or interest on,
      or any Additional Amounts with respect to, any Security of such series or
      any Coupons appertaining thereto, 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 of such series affected.

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

      Section 514. Waiver of Stay or Extension Laws.

      The Company covenants that (to the extent that it may lawfully do so) 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 expressly waives (to the extent
that it may lawfully do so) 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.

discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of any
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; provided, that

Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of Outstanding Securities of any
series, or to any suit instituted by any Holder for the enforcement of the
payment of the principal of (or premium, if any) or interest, if any, on or
Additional Amounts, if any, with respect to any Security, on or after the
respective Stated Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date, and, in the case of repayment, on
or after the date for repayment) or for the enforcement of the right, if any, to
convert or exchange any Security into Common Stock or other securities in
accordance with its terms.

      Section 601. Certain Duties and Responsibilities.

      (a) With respect to the Securities of any series, except during the
continuance of an Event of Default with respect to the Securities of such
series,

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

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

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

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

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

            (2) the Trustee shall not be liable for any error of judgment made
      in good faith by a Responsible Officer, unless it shall be proved that the

risk its own funds or otherwise incur any financial liability in the performance

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.

protection to the Trustee shall be subject to the provisions of this Section.

      bond, debenture, coupon or other paper or document, but the Trustee, in

      (as defined in Section 603) or Event of Default with respect to the
      Securities of any series for which it is acting as Trustee unless either
      (1) a Responsible Officer of the Trustee shall have actual knowledge that
      such default or Event of Default, as the case may be, exists and
      constitutes a default or Event of Default, as the case may be, under this
      Indenture, or (2) written notice of such default or Event of Default shall

Responsible Officers of the Trustee in good faith determine that the withholding
of such notice is in the best interest of the Holders of Securities and Coupons
of such series; and provided, further, that in the case of any default of the

representations as to the validity or sufficiency of this Indenture or the
Guarantee or of the Securities or the Coupons, except that the Trustee

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

      Section 606. Money Held in Trust.

      Except as provided in Section 403 and Section 1003, money held by the

extent required by law and shall

                                      -48-

be held uninvested. The Trustee shall be under no liability for interest on any
money received by it hereunder except as otherwise agreed in writing with the
Company.

      Section 607. Compensation and Reimbursement.

      The Company agrees:

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

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

            (3) to indemnify the Trustee and its agents for, and to hold them
      harmless against, any loss, damages, claims, liability or expense incurred
      without negligence or bad faith on their part, arising out of or in
      connection with the acceptance or administration of the trust or trusts
      hereunder, including the costs and expenses of defending themselves
      against any claim (whether asserted by the Company, or any Holder or any
      other Person) or liability in connection with the exercise or performance
      of any of their powers or duties hereunder or in connection with enforcing
      the provisions of this Section.

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

      In addition and without prejudice to the rights provided to the Trustee
under any of the provisions of this Indenture, when the Trustee incurs expenses
or renders services in connection with an Event of Default specified in Section
501(5) or Section 501(6), the expenses (including the reasonable charges and
expenses of its counsel) and the compensation for the services are intended to
constitute expenses of administration under any applicable bankruptcy,
insolvency or other similar law.

      The Company's obligations under this Section 607 and the lien referred to
in this Section 607 shall survive the resignation or removal of the Trustee, the
discharge of the Company's obligations under Article Four of this Indenture
and/or the termination of this Indenture. "Trustee" for purposes of this Section
607 shall include any predecessor Trustee but the negligence or bad faith of any
Trustee shall not affect the rights of any other Trustee under this Section 607.

Trust Indenture Act and that has a combined capital and surplus (computed in
accordance with Section 310(a)(2) of the Trust Indenture Act) of at least
$50,000,000 subject to supervision or examination by Federal or state authority.
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 609. Resignation and Removal; Appointment of Successor.

      (1) 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 pursuant to Section 610.

      (2) The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 610 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee or the removed Trustee, as the case
may be, may petition any court of competent jurisdiction for the appointment of
a successor Trustee with respect to such series.

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

      (4) If at any time:

            (a) the Trustee shall fail to comply with the obligations imposed
      upon it under Section 310(b) of the Trust Indenture Act with respect to
      Securities of any series after written request therefor by the Company or

      shall fail to resign after written request therefor by the Company or any
      such Holder, or

            (c) 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 or pursuant to a Board Resolution,
may remove the Trustee with respect to all Securities or the Securities of such
series, or (ii) subject to Section 315(e) of the Trust Indenture Act, any Holder
of a Security who has been a bona fide Holder of a Security of such series for
at least six months may, on behalf of himself and all others similarly

                                      -50-

Trustee with respect to all Securities of such series and the appointment of a
successor Trustee or Trustees.

Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series) and shall comply with the
applicable requirements of Section 610. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements of Section
610, become the successor Trustee with respect to the Securities of such series
and to that extent supersede the successor Trustee appointed by the Company. If
no successor Trustee with respect to the Securities of any series shall have
been so appointed by the Company or the Holders of Securities and accepted
appointment in the manner required by Section 610, any Holder of a Security who
has been a bona fide Holder of a Security of such series for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

Authorized Newspaper in each Place of Payment located outside the United States.

to all Securities, such successor Trustee so appointed shall execute,
acknowledge and deliver to the Company and 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 hereunder of the retiring Trustee; but, on the request
of the Company or such successor Trustee, such retiring Trustee, upon payment of
its charges, shall execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and,
subject to Section 1003, shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee
hereunder, subject nevertheless to its lien, if any, provided for in Section

to the Securities of one or more (but not all) series, the Company, the retiring
Trustee and such successor Trustee shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment
and which (a) shall contain such provisions as shall be necessary or desirable
to transfer and confirm to, and to vest in, such successor Trustee all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates, (b) if the retiring Trustee is not retiring with respect to all
Securities, shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series as to
which the retiring Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (c) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees
co-trustees of the same trust, that each such Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee and that no Trustee shall be responsible
for any notice given to, or received by, or any act or failure to act on the
part of any other Trustee hereunder, and, upon the execution and delivery of
such supplemental indenture, the resignation or removal of the retiring Trustee
shall become effective to the extent provided therein, such retiring Trustee
shall have no further responsibility for the exercise of rights and powers or
for the performance of the duties and obligations vested in the Trustee under
this Indenture with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates other than as hereinafter
expressly set forth, 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 with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates; but, on
request of the Company or such successor Trustee, such retiring Trustee, upon
payment of its charges with respect to the Securities of that or those series to
which the appointment of such successor relates and subject to Section 1003
shall duly assign, transfer and deliver to such successor Trustee, to the extent
contemplated by such supplemental indenture, the property and money held by such
retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates, subject to
its claim, if any, provided for in Section 607.

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

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

      Section 611. Merger, Conversion, Consolidation or Succession to Business.

      Any Person into which the Trustee may be merged or converted or with which
it may be consolidated, or any Person resulting from any merger, conversion or
consolidation to which the

                                      -52-
<PAGE>
Trustee shall be a party, or any Person succeeding to all or substantially all
of the corporate trust business of the Trustee, shall be the successor of the
Trustee hereunder, provided such Person shall otherwise be eligible under
Section 608, without the execution or filing of any paper or any further act on
the part of any of the parties hereto. In case any Securities shall have been
authenticated but not delivered by the Trustee then in office, any successor by
merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

      Section 612. Appointment of Authenticating Agent.

      The Trustee may appoint one or more Authenticating Agents acceptable to
the Company with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of that or
those series issued upon original issue, exchange, registration of transfer,
partial redemption or partial repayment, or pursuant to Section 306, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent.

      Each Authenticating Agent shall be acceptable to the Company and, except
as provided in or pursuant to this Indenture, shall at all times be a
Corporation that would be permitted by the Trust Indenture Act to act as trustee
under an indenture qualified under the Trust Indenture Act (including pursuant
to Section 310(a)(1) thereof), is authorized under applicable law and by its
charter to act as an Authenticating Agent and has a combined capital and surplus
(computed in accordance with Section 310(a)(2) of the Trust Indenture Act) of at
least $50,000,000. If at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect specified in this Section.

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

      An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall (i) mail written notice
of such appointment by first-class mail, postage prepaid, to all Holders of
Registered Securities, if any, of the series with respect to

                                      -53-
<PAGE>
which such Authenticating Agent shall serve, as their names and addresses appear
in the Security Register, and (ii) if Securities of the series are issued as
Bearer Securities, publish notice of such appointment at least once in an
Authorized Newspaper in the place where such successor Authenticating Agent has
its principal office if such office is located outside the United States. Any
successor Authenticating Agent, upon acceptance of its appointment hereunder,
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

      The Company agrees to pay each Authenticating Agent from time to time
reasonable compensation for its services under this Section. If the Trustee
makes such payments, it shall be entitled to be reimbursed for such payments,
subject to the provisions of Section 607.

      The provisions of Sections 308, 604 and 605 shall be applicable to each
Authenticating Agent.

      If an Authenticating Agent is appointed with respect to one or more series
of Securities pursuant to this Section, the Securities of such series may have
endorsed thereon, in addition to or in lieu of the Trustee's certificate of
authentication, an alternate certificate of authentication in substantially the
following form:

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

      If all of the Securities of any series may not be originally issued at one
time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment where the
Company wishes to have Securities of such series authenticated upon original
issuance, the Trustee, if so requested in writing (which writing need not be
accompanied by or contained in an Officers' Certificate by the Company), shall
appoint in accordance with this Section an Authenticating Agent having an office
in a Place of Payment designated by the Company with respect to such series of
Securities.

            (1) in case the Company shall consolidate with or merge into another
      Person or convey, transfer or lease its properties and assets
      substantially as an entirety to any Person, the Person formed by such
      consolidation or into which the Company is merged or the Person which
      acquired by conveyance, transfer or lease the properties and assets of the
      Company substantially as an entirety shall be a legal entity organized and
      existing under the laws of any domestic or foreign jurisdiction, and shall
      expressly assume, by an indenture supplemental hereto, executed and
      delivered to the Trustee, in form satisfactory to the Trustee, the due and
      punctual payment of the principal of and any premium and interest and
      Additional Amounts, if any, on all the Securities and the performance of

Conrail Spin Off Transactions, Guarantor shall be deemed to have directly
assumed the obligation to make due and punctual payment of the principal of and
any premium and interest and Additional Amounts, if any, on all the Securities
and perform every covenant of this Indenture on the part of the Company to be
performed or observed. Upon such assumption, Guarantor shall succeed to, and be

herein, and the Company shall be released from all obligations and covenants
with respect to the Securities.

      Upon any consolidation or merger by the Company with or into any other
Person, or any conveyance, transfer or lease by the Company of its properties
and assets substantially as an entirety to any Person in accordance with Section

Section 801) shall be discharged from all obligations and covenants under this
Indenture, the Securities and the Coupons and may be dissolved and liquidated.
The successor Person may cause to be signed, and may issue either in its own
name or in the name of the Company any or all of the Securities issuable
hereunder which theretofore shall not have been signed by the Company and
delivered to the Trustee; and, upon the Company Order of such successor Person
instead of the Company and subject to all the terms, conditions and limitations
in this Indenture prescribed, the Trustee, pursuant to the terms hereof, shall
authenticate and shall deliver any Securities together with any Coupons
appertaining thereto which previously shall have been signed and delivered by
the Officers to the Trustee for authentication, and any Securities which such
successor Person thereafter shall cause to be signed and delivered to the
Trustee for that purpose. All of the Securities so issued together with any
Coupons appertaining thereto shall in all respects have the same legal rank and
benefit under this Indenture as the Securities theretofore or thereafter issued
in accordance with the terms of this Indenture as though all of such Securities
had been issued at the date of the execution hereof. In case of any such
consolidation, merger, conveyance, transfer or lease, such changes in phrasing
and form (but not in substance) may be made in the Securities and the Coupons
thereafter to be issued as may be appropriate.

of such supplemental indenture and entitled to the benefits of such provision.

      Section 902. Supplemental Indentures with Consent of Holders.

      With the consent of the Holders of not less than a majority in aggregate
principal amount of the Outstanding Securities of all series affected by such

to the Company and the Trustee, the Company (when authorized by or pursuant to a
Board Resolution, which resolution may provide general terms or parameters for
such action and may provide that the specific terms of such action may be

Amounts.

      The Company covenants and agrees for the benefit of the Holders of the
Securities of each series that it will duly and punctually pay the principal of,
any premium and interest on and any Additional Amounts with respect to the
Securities of such series in accordance with the terms thereof, any Coupons
appertaining thereto and this Indenture. Any interest due on any Bearer Security

      Section 1002. Maintenance of Office or Agency.

      The Company shall maintain in each Place of Payment for any series of
Securities an Office or Agency where Securities of such series (but not Bearer
Securities, except as otherwise provided below, unless such Place of Payment is
located outside the United States) may be presented or surrendered for payment,
where Securities of such series may be surrendered for registration of transfer
or exchange, where Securities of such series that are convertible or
exchangeable may be surrendered for conversion or exchange, and where notices
and demands to or upon the Company in respect of the Securities of such series
relating thereto and this Indenture may be served. If Securities of a series are
issuable as Bearer Securities, the Company shall maintain, subject to any laws
or regulations applicable thereto, an Office or Agency in a Place of Payment for
such series which is located outside the United States where Securities of such
series and any Coupons appertaining thereto may be presented and surrendered for
payment; provided, however, that if the Securities of such series are listed on
The International Stock Exchange of the United Kingdom and the Republic of
Ireland or the Luxembourg Stock Exchange or any other stock exchange located
outside the United States and such stock exchange shall so require, the Company
shall maintain a Paying Agent in London, Luxembourg or any other required city
located outside the United States, as the case may be, so long as the Securities
of such series are listed on such exchange. The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of such
Office or Agency. If at any time the Company shall fail to maintain any such
required Office or Agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, except that Bearer
Securities of such series and any Coupons appertaining thereto may be presented
and surrendered for payment at the place specified for the purpose with respect
to such Securities as provided in or pursuant to this Indenture, and the Company
hereby appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands.

      Except as otherwise provided in or pursuant to this Indenture, no payment
of principal, premium, interest or Additional Amounts with respect to Bearer
Securities shall be made at any Office or Agency in the United States or by
check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, if
amounts owing with respect to any Bearer Securities shall be payable in Dollars,
payment of principal of, any premium or interest on and any Additional Amounts
with respect to any such Security may be made at the Corporate Trust Office of
the Trustee or any Office or Agency designated by the Company in the Borough of
Manhattan, The City of New York, if (but only if) payment of the full amount of
such principal, premium, interest or Additional Amounts at all offices outside
the United States maintained for such purpose by the Company in accordance with
this Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

      The Company may also from time to time designate one or more other Offices
or Agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an Office or Agency
in each Place of Payment for Securities of any series for such purposes. The
Company shall give prompt written notice to the Trustee of any such designation

                                      -62-
<PAGE>
or rescission and of any change in the location of any such other Office or
Agency. Unless otherwise provided in or pursuant to this Indenture, the Company
hereby designates as the Place of Payment for each series of Securities the
Borough of Manhattan, The City of New York, and initially appoints the Corporate
Trust Office of the Trustee as the Company's Office or Agency in the Borough of
Manhattan, The City of New York for such purpose. The Company may subsequently
appoint a different Office or Agency in the Borough of Manhattan, The City of
New York for the Securities of any series.

      Section 1003. Money for Securities Payments to be Held in Trust.

      If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it shall, on or before each due date of the
principal of, any premium or interest on or Additional Amounts with respect to
any of the Securities of such series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum in the Currency or Currencies in
which the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series) sufficient to pay the
principal or any premium, interest or Additional Amounts so becoming due until
such sums shall be paid to such Persons or otherwise disposed of as herein
provided, and shall promptly notify the Trustee of its action or failure so to
act.

      Whenever the Company shall have one or more Paying Agents for any series
of Securities, it shall, on or prior to each due date of the principal of, any
premium or interest on or any Additional Amounts with respect to any Securities
of such series, deposit with any Paying Agent a sum (in the Currency or
Currencies described in the preceding paragraph) sufficient to pay the principal
or any premium, interest or Additional Amounts so becoming due, such sum to be
held in trust for the benefit of the Persons entitled thereto, and (unless such
Paying Agent is the Trustee) the Company will promptly notify the Trustee of its
action or failure so to act.

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

      (1) hold all sums held by it for the payment of the principal of, any
premium or interest on or any Additional Amounts with respect to Securities of
such series in trust for the benefit of the Persons entitled thereto until such
sums shall be paid to such Persons or otherwise disposed of as provided in or
pursuant to this Indenture;

      (2) give the Trustee notice of any default by the Company in the making of
any payment of principal, any premium or interest on or any Additional Amounts
with respect to the Securities of such series; 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 terms as those upon which such sums were

                                      -63-
<PAGE>
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.

      Except as otherwise provided herein or pursuant hereto, 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, any premium or interest on or any
Additional Amounts with respect to any Security of any series or any Coupon
appertaining thereto and remaining unclaimed for two years after such principal
or any such premium or interest or any such Additional Amounts shall have become
due and payable shall be paid to the Company on Company Request, or (if then
held by the Company) shall be discharged from such trust; and the Holder of such
Security or any Coupon appertaining thereto 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 an Authorized Newspaper in each Place of Payment for such
series or to be mailed to Holders of Registered Securities of such series, or
both, 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
or mailing nor shall it be later than two years after such principal and any
premium or interest or Additional Amounts shall have become due and payable, any
unclaimed balance of such money then remaining will be repaid to the Company.

      Section 1004. Additional Amounts.

      If any Securities of a series provide for the payment of Additional
Amounts, the Company agrees to pay to the Holder of any such Security or any
Coupon appertaining thereto Additional Amounts as provided in or pursuant to
this Indenture or such Securities. Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of or any premium or
interest on, or in respect of, any Security of any series or any Coupon or the
net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of Additional
Amounts provided by the terms of such series established hereby or pursuant
hereto to the extent that, in such context, Additional Amounts are, were or
would be payable in respect thereof pursuant to such terms, and express mention
of the payment of Additional Amounts (if applicable) in any provision hereof
shall not be construed as excluding Additional Amounts in those provisions
hereof where such express mention is not made.

      Except as otherwise provided in or pursuant to this Indenture or the
Securities of any series, if the Securities of a series provide for the payment
of Additional Amounts, at least 10 days prior to the first Interest Payment Date
with respect to such series of Securities (or if the Securities of such series
shall not bear interest prior to Maturity, the first day on which a payment of
principal is made), and at least 10 days prior to each date of payment of
principal or interest if there has been any change with respect to the matters
set forth in the below-mentioned Officers' Certificate, the Company shall
furnish to the Trustee and the principal Paying Agent or Paying Agents, if other
than the Trustee, an Officers' Certificate instructing the Trustee and such
Paying Agent or Paying Agents whether such payment of principal of and premium,
if any, or interest, if any, on the Securities of such series shall be made to
Holders of Securities of such

                                      -64-
<PAGE>
series or the Coupons appertaining thereto who are United States Aliens without
withholding for or on account of any tax, assessment or other governmental
charge described in the Securities of such series. If any such withholding shall
be required, then such Officers' Certificate shall specify by country the
amount, if any, required to be withheld on such payments to such Holders of
Securities or Coupons, and the Company agrees to pay to the Trustee or such
Paying Agent the Additional Amounts required by the terms of such Securities.
The Company covenants to indemnify the Trustee and any Paying Agent for, and to
hold them harmless against, any loss, liability or expense reasonably incurred
without negligence or bad faith on their part arising out of or in connection
with actions taken or omitted by any of them in reliance on any Officers'
Certificate furnished pursuant to this Section.

      Section 1005. Company Statement as to Compliance.

      The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year, an Officer's Certificate, stating as to each signer, that

            (1) a review of the activities of the Company during such year and
      of performance under this Indenture has been made under his or her
      supervision; and

            (2) to the best of his or her knowledge, based on such review, (a)
      the Company has fulfilled all its obligations under this Indenture
      throughout such year, or, if there has been a material default in the
      fulfillment of any such obligation, specifying each such default known to
      him or her and the nature and status thereof, and (b) no event has
      occurred and is continuing which is, or after notice or lapse of time or
      both would become, an Event of Default under Section 501, or, if such an
      event has occurred and is continuing, specifying each such event known to
      him or her and the nature and status thereof.

      Section 1006. Limitation on Liens on Stock of the Principal Subsidiaries.

      Other than in connection with the Conrail Spin Off Transactions, neither
the Company nor Guarantor will, nor will the Company or Guarantor permit any of
its Subsidiaries to, create, assume, incur or suffer to exist any Lien upon any
stock or indebtedness, whether owned on the date of this Indenture or hereafter
acquired, of any Principal Subsidiary, to secure any Obligation (other than the
Securities) of the Company or Guarantor, any of their respective Subsidiaries or
any other Person, without in any such case making effective provision whereby
all of the Outstanding Securities shall be directly secured equally and ratably
with such Obligation for so long as such Obligation (other than the Securities)
shall be so secured.

      Section 1007. Waiver of Certain Covenants.


      The Company or Guarantor may omit in any particular instance to comply
with any term, provision or condition set forth in Sections 1006 and 1008 with
respect to the Securities of any series if before the time for such compliance
the Holders of not less than a majority in principal amount of the Outstanding
Securities of such series shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such 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


                                      -65-
<PAGE>
the Company and Guarantor and the duties of the Trustee in respect of any such
term, provision or condition shall remain in full force and effect.


     Section 1008. Existence; Conduct of Business.



     The Company will do or cause to be done all things necessary to preserve,
renew and keep in full force and effect its legal corporate existence and the
rights, licenses, permits, privileges and franchises it reasonably deems
necessary to the conduct of its business; provided that the foregoing shall not
prohibit any merger, consolidation, conveyance, transfer or lease not
prohibited under Article Eight.


                                 ARTICLE ELEVEN
                            REDEMPTION OF SECURITIES

      Section 1101. Applicability of Article.

      Redemption of Securities of any series at the option of the Company as
permitted or required by the terms of such Securities shall be made in
accordance with the terms of such Securities and (except as otherwise provided
herein or pursuant hereto) this Article.

      Section 1102. Election to Redeem; Notice to Trustee.

      The election of the Company to redeem any Securities shall be evidenced by
or pursuant to a Board Resolution. In case of any redemption at the election of
the Company of less than all of the Securities of any series, the Company shall,
not less than 20 nor more than 60 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date and of the principal amount of Securities of
such series to be redeemed and, in the event that the Company shall determine
that the Securities of any series to be redeemed shall be selected from
Securities of such series having the same issue date, interest rate or interest
rate formula, Stated Maturity and other terms (the "Equivalent Terms"), the
Company shall notify the Trustee of such Equivalent Terms.

      Section 1103. Selection by Trustee of Securities to be Redeemed.

      If less than all of the Securities of any series are to be redeemed or if
less than all of the Securities of any series with Equivalent Terms are to be
redeemed, the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee from the Outstanding
Securities of such series or from the Outstanding Securities of such series with
Equivalent Terms, as the case may be, not previously called for redemption, by
such method as the Trustee shall deem fair and appropriate and which may provide
for the selection for redemption of portions of the principal amount of
Registered Securities of such series; provided, however, that no such partial
redemption shall reduce the portion of the principal amount of a Registered
Security of such series not redeemed to less than the minimum denomination for a
Security of such series established herein or pursuant hereto.

      The Trustee shall promptly notify the Company and the Security Registrar
(if other than itself) in writing of the Securities selected for redemption and,
in the case of any Securities selected for partial redemption, the principal
amount thereof to be redeemed.

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

      Unless otherwise specified in or pursuant to this Indenture or the
Securities of any series, if any Security selected for partial redemption is
converted or exchanged for Common Stock or

                                      -66-
<PAGE>
other securities in part before termination of the conversion or exchange right
with respect to the portion of the Security so selected, the converted or
exchanged portion of such Security shall be deemed (so far as may be) to be the
portion selected for redemption. Securities which have been converted or
exchanged during a selection of Securities to be redeemed shall be treated by
the Trustee as Outstanding for the purpose of such selection.

      Section 1104. Notice of Redemption.

      Notice of redemption shall be given in the manner provided in Section 106,
not less than 20 nor more than 60 days prior to the Redemption Date, unless a
shorter period is specified in the Securities to be redeemed, to the Holders of
Securities to be redeemed. Failure to give notice by mailing in the manner
herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such
Holder, shall not affect the validity of the proceedings for the redemption of
any other Securities or portion thereof.

      Any notice that is mailed to the Holder of any Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not such Holder receives the notice.

      All notices of redemption shall state:

      (1) the Redemption Date,

      (2) the Redemption Price,

      (3) if less than all Outstanding Securities of any series are to be
redeemed, the identification (and, in the case of partial redemption, the
principal amount) of the particular Security or Securities to be redeemed,

      (4) in case any Security is to be redeemed in part only, the notice which
relates to such Security shall state that on and after the Redemption Date, upon
surrender of such Security, the Holder of such Security will receive, without
charge, a new Security or Securities of authorized denominations for the
principal amount thereof remaining unredeemed,

      (5) that, on the Redemption Date, the Redemption Price shall become due
and payable upon each such Security or portion thereof to be redeemed, and, if
applicable, that interest thereon shall cease to accrue on and after said date,

      (6) the place or places where such Securities, together (in the case of
Bearer Securities) with all Coupons appertaining thereto, if any, maturing after
the Redemption Date, are to be surrendered for payment of the Redemption Price
and any accrued interest and Additional Amounts pertaining thereto,

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

      (8) that, unless otherwise specified in such notice, Bearer Securities of
any series, if any, surrendered for redemption must be accompanied by all
Coupons maturing subsequent to the date fixed for redemption or the amount of
any such missing Coupon or Coupons will be

                                      -67-
<PAGE>
deducted from the Redemption Price, unless security or indemnity satisfactory to
the Company, the Trustee and any Paying Agent is furnished,

      (9) if Bearer Securities of any series are to be redeemed and any
Registered Securities of such series are not to be redeemed, and if such Bearer
Securities may be exchanged for Registered Securities not subject to redemption
on the Redemption Date pursuant to Section 305 or otherwise, the last date, as
determined by the Company, on which such exchanges may be made,

      (10) in the case of Securities of any series that are convertible or
exchangeable into Common Stock or other securities, the conversion or exchange
price or rate, the date or dates on which the right to convert or exchange the
principal of the Securities of such series to be redeemed will commence or
terminate and the place or places where such Securities may be surrendered for
conversion or exchange, and

      (11) the CUSIP number or the Euroclear Operator or the Cedel S.A.
reference numbers of such Securities, if any (or any other numbers used by a
Depository to identify such Securities).

      A notice of redemption published as contemplated by Section 106 need not
identify particular Registered Securities to be redeemed.

      Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

      Section 1105. Deposit of Redemption Price.

      On or prior to any Redemption Date, the Company shall deposit, with
respect to the Securities of any series called for redemption pursuant to
Section 1104, with the Trustee or with a Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust as provided in
Section 1003) an amount of money in the applicable Currency sufficient to pay
the Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date, unless otherwise specified pursuant to Section 301 for or in the
Securities of such series) any accrued interest on and Additional Amounts with
respect thereto, all such Securities or portions thereof which are to be
redeemed on that date.

      Section 1106. Securities Payable on Redemption Date.

      Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest and the Coupons for such
interest appertaining to any Bearer Securities so to be redeemed, except to the
extent provided below, shall be void. Upon surrender of any such Security for
redemption in accordance with said notice, together with all Coupons, if any,
appertaining thereto maturing after the Redemption Date, such Security shall be
paid by the Company at the Redemption Price, together with any accrued interest
and Additional Amounts to the Redemption Date; provided, however, that, except
as otherwise provided in or pursuant to this Indenture or the Bearer


                                      -68-
<PAGE>
Securities of such series, installments of interest on Bearer Securities whose
Stated Maturity is on or prior to the Redemption Date shall be payable only upon
presentation and surrender of Coupons for such interest (at an Office or Agency
located outside the United States except as otherwise provided in Section 1002),
and provided, further, that, except as otherwise specified in or pursuant to
this Indenture or the Registered Securities of such series, installments of
interest on Registered Securities whose Stated Maturity is on or prior to the
Redemption Date shall be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
Regular Record Dates therefor according to their terms and the provisions of
Section 307.

      If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant Coupons maturing after the Redemption Date, such Security may
be paid after deducting from the Redemption Price an amount equal to the face
amount of all such missing Coupons, or the surrender of such missing Coupon or
Coupons may be waived by the Company and the Trustee if there be furnished to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender
to the Trustee or any Paying Agent any such missing Coupon in respect of which a
deduction shall have been made from the Redemption Price, such Holder shall be
entitled to receive the amount so deducted; provided, however, that any interest
or Additional Amounts represented by Coupons shall be payable only upon
presentation and surrender of those Coupons at an Office or Agency for such
Security located outside of the United States except as otherwise provided in
Section 1002.

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

      Section 1107. Securities Redeemed in Part.

      Any Registered Security which is to be redeemed only in part shall be
surrendered at any Office or Agency for such Security (with, if the Company or
the Trustee so requires, due endorsement by, or a written instrument of transfer
in form satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or his attorney duly authorized in writing) and the Company shall
execute and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Registered Security or Securities of the
same series, containing identical terms and provisions, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so
surrendered. If a Security in global form is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the Depository for
such Security in global form as shall be specified in the Company Order with
respect thereto to the Trustee, without service charge, a new Security in global
form in a denomination equal to and in exchange for the unredeemed portion of
the principal of the Security in global form so surrendered.

                                  SINKING FUNDS

      Section 1201. Applicability of Article.

      The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series, except as otherwise permitted or
required in or pursuant to this Indenture or any Security of such series issued
pursuant to this Indenture.

      The minimum amount of any sinking fund payment provided for by the terms
of Securities of any series is herein referred to as a "mandatory sinking fund
payment", and any payment in excess of such minimum amount provided for by the
terms of Securities of such series is herein referred to as an "optional sinking
fund payment". If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 1202. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of Securities of such
series and this Indenture.

      Section 1202. Satisfaction of Sinking Fund Payments with Securities.

      The Company may, in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of any series to be made pursuant to the
terms of such Securities (1) deliver Outstanding Securities of such series
(other than any of such Securities previously called for redemption or any of
such Securities in respect of which cash shall have been released to the Company
(as described below)), together in the case of any Bearer Securities of such
series with all unmatured Coupons appertaining thereto, and (2) apply as a
credit Securities of such series which have been redeemed either at the election
of the Company pursuant to the terms of such series of Securities or through the
application of permitted optional sinking fund payments pursuant to the terms of
such Securities, provided that such Securities have not been previously so
credited. Such Securities shall be received and credited for such purpose by the
Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly. If as a result of the delivery or credit
of Securities of any series in lieu of cash payments pursuant to this Section
1202, the principal amount of Securities of such series to be redeemed in order
to exhaust the aforesaid cash payment shall be less than $100,000, the Trustee
need not call Securities of such series for redemption, except upon Company
Request, and such cash payment shall be held by the Trustee or a Paying Agent
and applied to the next succeeding sinking fund payment, provided, however, that
the Trustee or such Paying Agent shall at the request of the Company from time
to time pay over and deliver to the Company any cash payment so being held by
the Trustee or such Paying Agent upon delivery by the Company to the Trustee of
Securities of that series purchased by the Company having an unpaid principal
amount equal to the cash payment requested to be released to the Company.

      Section 1203. Redemption of Securities for Sinking Fund.

      Not less than 75 days prior to each sinking fund payment date for any
series of Securities, the Company shall deliver to the Trustee an Officers'
Certificate specifying the amount of the

                                      -70-
<PAGE>
next ensuing mandatory sinking fund payment for that series pursuant to the
terms of that series, the portion thereof, if any, which is to be satisfied by
payment of cash and the portion thereof, if any, which is to be satisfied by
delivering and crediting of Securities of that series pursuant to Section 1202,
and the optional amount, if any, to be added in cash to the next ensuing
mandatory sinking fund payment, and will also deliver to the Trustee any
Securities to be so credited and not theretofore delivered. If such Officers'
Certificate shall specify an optional amount to be added in cash to the next
ensuing mandatory sinking fund payment, the Company shall thereupon be obligated
to pay the amount therein specified. Not less than 45 days before each such
sinking fund payment date the Trustee shall select the Securities to be redeemed
upon such sinking fund payment date in the manner specified in Section 1103 and
cause notice of the redemption thereof to be given in the name of and at the
expense of the Company in the manner provided in Section 1104. Such notice
having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in Sections 1106 and 1107.

                                ARTICLE THIRTEEN
                       REPAYMENT AT THE OPTION OF HOLDERS

      Section 1301. Applicability of Article.

      Securities of any series which are repayable at the option of the Holders
thereof before their Stated Maturity shall be repaid in accordance with the
terms of the Securities of such series. The repayment of any principal amount of
Securities pursuant to such option of the Holder to require repayment of
Securities before their Stated Maturity, for purposes of Section 309, shall not
operate as a payment, redemption or satisfaction of the indebtedness represented
by such Securities unless and until the Company, at its option, shall deliver or
surrender the same to the Trustee with a directive that such Securities be
cancelled. Notwithstanding anything to the contrary contained in this Section
1301, in connection with any repayment of Securities, the Company may arrange
for the purchase of any Securities by an agreement with one or more investment
bankers or other purchasers to purchase such Securities by paying to the Holders
of such Securities on or before the close of business on the repayment date an
amount not less than the repayment price payable by the Company on repayment of
such Securities, and the obligation of the Company to pay the repayment price of
such Securities shall be satisfied and discharged to the extent such payment is
so paid by such purchasers.

                                ARTICLE FOURTEEN
                        SECURITIES IN FOREIGN CURRENCIES

      Section 1401. Applicability of Article.

      Whenever this Indenture provides for any distribution to Holders of
Securities of any series in which not all of such Securities are denominated in
the same Currency, in the absence of any provision to the contrary in or
pursuant to this Indenture or the Securities of such series, any amount in
respect of any Security denominated in a Currency other than Dollars shall be
treated for any such distribution as that amount of Dollars that could be
obtained for such amount on such reasonable basis of exchange and as of the
record date with respect to Registered Securities of such series (if any) for
such distribution (or, if there shall be no applicable record date, such other
date reasonably proximate to the date of such distribution) as the Company may

                                      -71-
<PAGE>
specify in a written notice to the Trustee or, in the absence of such written
notice, as the Trustee may determine.

                                 ARTICLE FIFTEEN
                        MEETINGS OF HOLDERS OF SECURITIES

      Section 1501. Purposes for Which Meetings may be Called.

      A meeting of Holders of Securities of any one or more series may be called
at any time and from time to time pursuant to this Article to make, give or take
any request, demand, authorization, direction, notice, consent, waiver or other
Act provided by this Indenture to be made, given or taken by Holders of
Securities of the relevant series.

      Section 1502. Call, Notice and Place of Meetings.

      (1) The Trustee may at any time call a meeting of Holders of Securities of
any one or more series for any purpose specified in Section 1501, to be held at
such time and at such place in the Borough of Manhattan, The City of New York,
or, if Securities of such one or more series have been issued in whole or in
part as Bearer Securities, in London or in such place outside the United States
as the Trustee shall determine. Notice of every meeting of Holders of Securities
of any one or more series, setting forth the time and the place of such meeting
and in general terms the action proposed to be taken at such meeting, shall be
given to the Holders of Securities of the relevant series, in the manner
provided in Section 106, not less than 21 nor more than 180 days prior to the
date fixed for the meeting.

      (2) In case at any time the Company (by or pursuant to a Board Resolution)
or the Holders of at least 10% in principal amount of the Outstanding Securities
of any one or more series entitled to vote on a matter as a group shall have
requested the Trustee to call a meeting of the Holders of Securities of the
applicable series for any purpose specified in Section 1501, by written request
setting forth in reasonable detail the action proposed to be taken at the
meeting, and the Trustee shall not have mailed notice of or made the first
publication of the notice of such meeting within 21 days after receipt of such
request (whichever shall be required pursuant to Section 106) or shall not
thereafter proceed to cause the meeting to be held as provided herein, then the
Company or the Holders of Securities of such series in the amount above
specified, as the case may be, may determine the time and the place in the
Borough of Manhattan, The City of New York, or, if Securities of such applicable
series are to be issued as Bearer Securities, in London for such meeting and may

      Section 1504. Quorum; Action.

      The Persons entitled to vote a majority in principal amount of the

Holders of Securities of such series; provided, however, that with respect to a
consent or waiver as contemplated in Section 902, the Persons entitled to vote a
majority in aggregate principal amount of the Outstanding Securities of all
series affected by any such supplemental indenture shall constitute a quorum for
a meeting of Holders of Securities of all such series; provided, further,
however, if any action is to be taken at such meeting with respect to a consent
or waiver which this Indenture expressly provides may be given by the Holders of
not less than a specified percentage in principal amount of the Outstanding
Securities of one or more series, the Persons holding or representing such
specified percentage in principal amount of the Outstanding Securities of the
applicable series shall constitute a quorum. In the absence of a quorum within
30 minutes after the time appointed for any such meeting, the meeting shall, if
convened at the request of Holders of Securities of such applicable series, be
dissolved. In any other case the meeting may be adjourned for a period of not
less than 10 days as determined by the chairman of the meeting prior to the
adjournment of such meeting. In the absence of a quorum at any such adjourned
meeting, such adjourned meeting may be further adjourned for a period of not

provided, however, that, with respect to a consent or waiver contemplated in
Section 902, any resolution presented to a meeting or adjourned meeting duly
reconvened at which a quorum is present as aforesaid may be adopted only by the
affirmative vote of the Holders of a majority in aggregate principal amount of
the Outstanding Securities of all series affected by any such supplemental
indenture (voting as a single class); provided, however, that, except as limited
by the proviso to Section 902, any resolution with respect to any consent or
waiver which this Indenture expressly provides may be given by the Holders of
not less than a specified percentage in principal amount of the Outstanding

reconvened and at which a quorum is present as aforesaid by the affirmative vote
of the Holders of such specified percentage in principal amount of the
Outstanding Securities of the applicable series.

      Any resolution passed or decision taken at any meeting of Holders of
Securities of any one or more series duly held in accordance with this Section
shall be binding on all the Holders of Securities of such applicable series and
the Coupons appertaining thereto, whether or not such Holders were present or
represented at the meeting.

      Section 1505. Determination of Voting Rights; Conduct and Adjournment of
Meetings.

      (1) Notwithstanding any other provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of any applicable series in regard to proof of the holding
of Securities of such series and of the appointment of proxies and in regard to
the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem
appropriate. Except as otherwise permitted or required by any such regulations,
the holding of Securities shall be proved in the manner specified in Section 104
and the appointment of any proxy shall be proved in the manner specified in
Section 104 or by having the signature of the person executing the proxy
witnessed or guaranteed by any trust company, bank or banker authorized by
Section 104 to certify to the holding of Bearer Securities. Such regulations may
provide that written instruments appointing proxies, regular on their face, may
be presumed valid and genuine without the proof specified in Section 104 or
other proof.

      (2) The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Securities as provided in Section 1502(2), in which
case the Company or the Holders of Securities of the one or more series calling
the meeting, as the case may be, shall in like manner appoint a temporary
chairman. A permanent chairman and a permanent secretary of the meeting shall be
elected by vote of the Persons entitled to vote a majority in principal amount
of the Outstanding Securities of such applicable series represented at the
meeting.

      (3) Unless otherwise provided in or pursuant to a Security, at any
meeting, each Holder of a Security of such applicable series or proxy shall be
entitled to one vote for each $1,000 principal amount of Securities of such
applicable series held or represented by him; provided, however, that no vote
shall be cast or counted at any meeting in respect of any Security challenged as
not Outstanding and ruled by the chairman of the meeting to be not Outstanding.
The chairman of the meeting shall have no right to vote, except as a Holder of a
Security of such applicable series or proxy.

      (4) Any meeting of Holders of Securities of any one or more series duly
called pursuant to Section 1502 at which a quorum is present may be adjourned
from time to time by Persons entitled to vote a majority in principal amount of
the Outstanding Securities of such applicable series represented at the meeting;
and the meeting may be held as so adjourned without further notice.

      Section 1506. Counting Votes and Recording Action of Meetings.

      The vote upon any resolution submitted to any meeting of Holders of
Securities of any one or more series shall be by written ballots on which shall
be subscribed the signatures of the Holders of Securities of the applicable
series or of their representatives by proxy and the principal amounts and serial
numbers of the Outstanding Securities of the applicable series held or
represented by them. The permanent chairman of the meeting shall appoint two
inspectors of votes who shall count all votes cast at the meeting for or against
any resolution and who shall make and file with the secretary of the meeting
their verified written reports in triplicate of all votes cast at the meeting. A
record, at least in triplicate, of the proceedings of each meeting of Holders of
Securities of any one or more series shall be prepared by the secretary of the
meeting and there shall be attached to said record the original reports of the
inspectors of votes on any vote by ballot taken thereat and affidavits by one or
more persons having knowledge of the facts setting forth a copy of the notice of
the meeting and showing that said notice was given as provided in Section 1502
and, if applicable, Section 1504. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

                                 ARTICLE SIXTEEN
                                    GUARANTEE

      Section 1601. Guarantee.

      Subject to the provisions of this Article Sixteen, Guarantor hereby fully,
unconditionally and irrevocably guarantees on a senior unsecured basis to each
Holder of any series of Securities and to the Trustee on behalf of the Holders
of the Securities, the full and punctual payment (whether at maturity, upon
redemption, or otherwise) of the principal of, any premium and interest on and
any Additional Amounts with respect to each of the Securities in accordance with
the terms of such Securities, any Coupons appertaining thereto and this
Indenture. Upon failure by the Company to pay punctually any such amount with
respect to a series of Securities, Guarantor shall forthwith on demand pay the
amount not so paid with respect to such series of Securities at the place and in
the manner specified in this Indenture. Guarantor hereby waives diligence,
presentment, demand of payment, filing of claims with a court in the event of
bankruptcy of the Company, any right to require a proceeding first against the
Company, the benefit of discussion, protest or notice with respect to any such
Security or the debt evidenced thereby and all demands whatsoever, and covenants
that, except as set forth in Section 1604(1), its Guarantee will not be
discharged as to any such series of Securities except by payment in full of the
principal of, any premium and interest on and any Additional Amounts with
respect to such Securities in accordance with the terms of such Securities, any
Coupons appertaining thereto and this Indenture or by discharge and/or
defeasance pursuant to Section 401 or 402, as applicable. The maturity of the
obligations guaranteed hereby may be accelerated as provided in Article Five for
the purposes of this Article Sixteen. In the event of any declaration of
acceleration of such obligations as provided in Article Five which is not
thereafter rescinded or annulled or otherwise waived pursuant to this Indenture
or the relevant Securities, such obligations (whether or not due and payable)
shall forthwith become due and payable by

                                      -75-
<PAGE>
Guarantor for the purpose of this Article Sixteen, for so long as such
declaration of acceleration with respect to the applicable Securities has not
been rescinded or annulled or such default has not been waived.

      If the Trustee or the Holder of any Security is required by any court or
otherwise to return to the Company or Guarantor, or any custodian, receiver,
liquidator, trustee, sequestrator or other similar official acting in relation
to the Company or Guarantor, any amount paid to the Trustee or such Holder in
respect of a Security, this Guarantee, subject to Section 1604(1), to the extent
theretofore discharged, shall be reinstated in full force and effect with
respect to such series of Securities. Guarantor further agrees, to the fullest
extent that it may lawfully do so, that, as between it, on the one hand, and the
Holders of such series of Securities and the Trustee, on the other hand, the
maturity of the obligations guaranteed hereby may be accelerated as provided in
Article Five hereof for the purposes of its Guarantee, notwithstanding any stay,
injunction or other prohibition existing under any applicable bankruptcy law
preventing such acceleration in respect of the obligations guaranteed hereby.

      Guarantor hereby further agrees that its obligations under this Indenture
and the Securities shall be unconditional, regardless of the validity,
regularity or enforceability of this Indenture or the Securities, the absence of
any action to enforce this Indenture or the Securities, any waiver or consent by
any Holder of the Securities with respect to any provisions of this Indenture or
the Securities, any modification or amendment of, or supplement to, this
Indenture or the Securities, the recovery of any judgment against the Company or
any action to enforce any such judgment, or any other circumstance that might
otherwise constitute a legal or equitable discharge or defense of a Guarantor.

      Guarantor hereby irrevocably defers, until the principal of, any premium
and interest on and any Additional Amounts with respect to the relevant series
of Securities shall have been paid in full, any claim or other rights which it
may now have or hereafter acquire against the Company that arise from the
existence, payment, performance or enforcement of its obligations under its
Guarantee and this Indenture, including, without limitation, any right of
subrogation, reimbursement, exoneration, contribution, indemnification, any
right to participate in any claim or remedy of the Holders of such Securities
against the Company or any collateral which any such Holder of such Securities
or the Trustee on behalf of such Holder of such Securities hereafter acquires,
whether or not such claim, remedy or right arises in equity, or under contract,
statute or common law, including, without limitation, the right to take or
receive from the Company, directly or indirectly, in cash or other property or
by set-off or in any other manner, payment or security on account of such claim
or other rights. If any amount shall be paid to Guarantor in violation of the
preceding sentence and the principal of, any premium and interest on and any
Additional Amounts with respect to each of the relevant Securities shall not
have been paid in full, such amount shall be deemed to have been paid to
Guarantor for the benefit of, and held in trust for the benefit of, the Holders
of such Securities, and shall forthwith be paid to the Trustee for the benefit
of the Holders of such Securities to be credited and applied upon the principal
of, any premium and interest on and any Additional Amounts with respect to each
of such Securities. Guarantor acknowledges that it will receive direct and
indirect benefits from the issuance of the Securities pursuant to this Indenture
and that the waivers set forth in this Section 1601 are knowingly made in
contemplation of such benefits.

                                      -76-
<PAGE>
      The Guarantee set forth in this Section 1601 shall not be valid or become
obligatory for any purpose with respect to a Security until the certificate of
authentication on such Security shall have been signed by or on behalf of the
Trustee.

      Section 1602. Notice to Trustee.

      Guarantor shall give prompt written notice to the Trustee of any fact
known to Guarantor which would prohibit the making of any payment to or by the
Trustee in respect of its Guarantee pursuant to the provisions of this Article
Sixteen.

      Section 1603. Limitation on Amount of Guarantee.

      Notwithstanding anything to the contrary in this Article, Guarantor, and
by its acceptance of Securities, each Holder of Securities, hereby confirms that
it is the intention of all such parties that the Guarantee of Guarantor not
constitute a fraudulent conveyance under applicable fraudulent conveyance
provisions of the United States Bankruptcy Code or any comparable provision of
other U.S. and non-U.S. law. To effectuate that intention, the Trustee, the
Holders of Securities and Guarantor hereby irrevocably agree that the
obligations of Guarantor under the Guarantee are limited to the maximum amount
that would not render Guarantor's obligations subject to avoidance under
applicable fraudulent conveyance provisions of the United States Bankruptcy Code
or any comparable provision of other U.S. and non-U.S. law.

      Section 1604. Release of Guarantee.

      This Guarantee of Guarantor will terminate upon:

            (1) The merger of the Company with and into Guarantor; or

            (2) Defeasance or discharge of the Securities, as provided in
      Article Four.

      Upon delivery by the Company to the Trustee (a) in the case of clause (1),
if required, of the documents contemplated by Section 801, or (b) in the case of
clause (2), of the Officers' Certificate and Opinion of Counsel contemplated by
Section 401 or 402, the Trustee will in each case execute any documents
reasonably required in order to evidence the release of Guarantor from its
obligations under the Guarantee.

      Upon termination of the Guarantee pursuant to clause (1) above, Guarantor
will succeed to, and be substituted for, and may exercise every right and power
of, the Company under this Indenture and each of the Securities.

                                    * * * * *

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