officer knows, or in the exercise of reasonable care should know, that the
opinion with respect to the matters upon which his certificate or opinion is
based are erroneous. Any such Opinion of Counsel may be based, insofar as it
relates to factual matters, upon a certificate or opinion of, or representations
by, an officer or officers of the Company stating that the information with
respect to such factual matters is in the possession of the Company unless such
counsel knows, or in the exercise of reasonable care should know, that the
certificate or opinion or representations with respect to such matters are
erroneous.

     Where any Person is required to make, give or execute two or more
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 shall become effective when such instrument or instruments
or record or both 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

                                       12
<PAGE>

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 U.S. 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 U.S.
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 U.S. 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.

                                       13
<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; provided that no such authorization, agreement
or consent by the Holders of Registered Securities shall be deemed effective
unless it shall become effective pursuant to the provisions of this Indenture
not later than six months after the 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 or the Company in reliance thereon, whether or not notation of such
Act is made upon such Security.

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

     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 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 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.

     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,

                                       14
<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 108.  Conflict with Trust Indenture Act.

                                       15
<PAGE>

     If any provision hereof limits, qualifies or conflicts with any duties
under any required provision of the Trust Indenture Act imposed hereon by
Section 318(c) thereof, such required provision shall control.

     Section 109.  Effect of Headings and Table of Contents.

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

     Section 110.  Successors and Assigns.

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

     Section 111.  Separability Clause.

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

     Section 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, the holders of Senior
Indebtedness 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, 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.  Legal Holidays.

     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 be a Legal Holiday 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

                                       16
<PAGE>

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, Stated Maturity or Maturity, as the case may be, to the next succeeding
Business Day.

     Section 115.  Counterparts.

     This Indenture may be executed in several counterparts, each of which shall
be an original and all of which shall constitute but one and the same
instrument.

     Section 116.  Judgment Currency.

     The Company agrees, to the fullest extent that it may effectively do so
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 that 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.

     Section 201.  Forms Generally.

     Each Registered Security, Bearer Security, Coupon and temporary or
permanent global Security issued pursuant to this Indenture shall be in the form
established by or pursuant to a Board Resolution or in one or more indentures
supplemental hereto, shall have such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by or pursuant
to this Indenture or any indenture supplemental hereto and may have such
letters, numbers or other marks of identification and such legends or
endorsements placed thereon as may, consistently herewith, be

                                       17
<PAGE>

determined by the officers executing such Security or Coupon as evidenced by
their execution of such Security or Coupon.

     Unless otherwise provided in or pursuant to this Indenture or any
Securities, the Securities shall be issuable in registered form without Coupons.

     Definitive Securities and definitive Coupons shall be printed, lithographed
or engraved or produced by any combination of these methods on a steel engraved
border or steel engraved borders or may be produced in any other manner, all as
determined by the officers of the Company executing such Securities or Coupons,
as evidenced by their execution of such Securities or Coupons.

     Section 202.  Form of Trustee's Certificate of Authentication.

     Subject to Section 611, the Trustee's certificate of authentication shall

     Section 203.  Securities in Global Form.

     Unless otherwise provided in or pursuant to this Indenture or any
Securities, the Securities shall not be issuable in global form. If Securities
of a series shall be issuable in temporary or permanent global form, any such
Security may provide that it or any number of such Securities shall represent
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
exchanges. Any endorsement of any Security in global form to reflect the amount,
or any increase or decrease in the amount, or changes in the rights of Holders,
of Outstanding Securities represented thereby shall be made in such manner and
by such Person or Persons as shall be specified therein or in the Company Order
to be delivered pursuant to Section 303 or 304 with respect thereto. Subject to
the provisions of Section 303 and, if applicable, Section 304, the Trustee shall
deliver and redeliver any Security in permanent global form in the manner and
upon instructions given by the Person or Persons specified therein or in the
applicable Company Order. If a Company Order pursuant to Section 303 or 304 has
been, or simultaneously is, delivered,

                                       18
<PAGE>

any instructions by the Company with respect to a Security in global form shall
be in writing but need not be 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.

     Notwithstanding the provisions of Section 308 and except as provided in the
preceding paragraph, the Company, the Trustee and any agent of the Company and
the Trustee shall treat as the Holder of such principal amount of Outstanding
Securities represented by a global Security (i) in the case of a global Security
in registered form, the Holder of such global Security in registered form, or
(ii) in the case of a global Security in bearer form, the Person or Persons
specified pursuant to Section 301.

     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

     be determined with reference to an index, formula or other method or
     methods (which index, formula or method or methods may be based, without
     limitation, on one or more Currencies, commodities, equity indices or other
     indices), and, if so, the terms and conditions upon which and the manner in
     which such amounts shall be determined and paid or payable;

          (18) any deletions from, modifications of or additions to the Events
     of Default or covenants of the Company with respect to any of such
     Securities, whether or not such Events of Default or covenants are
     consistent with the Events of Default or covenants set forth herein;

          (19) if either or both of Section 402(2) relating to defeasance or
     Section 402(3) relating to covenant defeasance shall not be applicable to
     the Securities of such series, or any covenants in addition to those
     specified in Section 402(3) relating to the Securities of such series which
     shall be subject to covenant defeasance, and any deletions from, or
     modifications or additions to, the provisions of Article Four in respect of
     the Securities of such series;

          (20) if any of such Securities are to be issuable upon the exercise of
     warrants, and the time, manner and place for such Securities to be
     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
     exchange of a temporary Security) only upon receipt of certain certificates
     or other documents or satisfaction of other conditions, then the form and
     terms of such certificates, documents or conditions;

          (22) if there is more than one Trustee, the identity of the Trustee
     and, if not the Trustee, the identity of each Security Registrar, Paying
     Agent or Authenticating Agent with respect to such Securities; and

                                       22
<PAGE>

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

     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 the Bearer Securities denominated in Dollars
shall be issuable in the denomination of $5,000. Securities not denominated in
Dollars shall be issuable 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 of
the Company shall bind the Company, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the

                                       23
<PAGE>

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 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 of the
     Company, delivered by a duly authorized officer of the Company 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

          (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 laps
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

                                       24
<PAGE>

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 611 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 Coupons and with
such appropriate insertions, omissions, substitutions and other variations as
the Officer of the Company 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

                                       25
<PAGE>

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.

     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

                                       26
<PAGE>

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 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

                                       27
<PAGE>

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 U.S. Depository or such
other Depository as shall be specified in the Company Order with respect
thereto, and in accordance with instructions given to the Trustee and the U.S.
Depository or such other Depository, as the case may be (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 the U.S. Depository, as the case may be, or such other
Depository or U.S. 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
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.

                                       28
<PAGE>

     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
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

                                       29
<PAGE>

     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.

                                       30
<PAGE>

     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,
     The City of New York, but such publication shall not be a condition

     proposed payment of such

                                       31
<PAGE>

     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, the Trustee and any agent of the Company 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,
the Trustee or any agent of the Company or the Trustee shall be affected by
notice to the contrary.

     The Company, the Trustee and any agent of the Company 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

                                       32
<PAGE>

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, the Trustee or any
agent of the Company 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 a Depository shall have any rights under this Indenture with respect
to such global Security, and such Depository may be treated by the Company, the
Trustee, and any agent of the Company or the Trustee as the owner of such global
Security for all purposes whatsoever. None of the Company, the Trustee, any
Paying Agent or the Security Registrar will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests of a global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

     Section 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 destroyed by the Trustee, 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 OF INDENTURE

     Section 401.  Satisfaction and Discharge.

     Upon the direction of the Company by a Company Order, this Indenture 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

                                       33
<PAGE>

Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture 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 1107, 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 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;

                                       34
<PAGE>

          (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 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 with
respect to any series of Securities, the obligations of the Company to the
Trustee under Section 605 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
shall be deemed to have been discharged from its 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 other
obligations under such Securities and any Coupons appertaining thereto and this
Indenture insofar as such Securities and any Coupons appertaining thereto are
concerned (and the Trustee, at the expense of

                                       35
<PAGE>

the Company, shall execute proper instruments acknowledging the same), except
for the following 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.

     (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
shall be released from its obligations under any 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(9) 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:

          (a)  The Company shall irrevocably have deposited or caused to be
     deposited with the Trustee (or another trustee satisfying the requirements
     of Section 607 who shall agree to comply with the provisions of this
     Section 402 applicable to it) as trust funds in trust for the purpose of
     making the following payments, specifically pledged as security for, and

                                       36
<PAGE>

     dedicated solely to, the benefit of the Holders of such Securities and any
     Coupons appertaining thereto, (1) 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 any case, in
     an amount, 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)  Solely in the case of an election under clause (2) of this
     Section 402, 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 on the date of such deposit or 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.

          (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.

                                       37
<PAGE>

          (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 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.

                                       38
<PAGE>

     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 404.  Effect on Subordination Provisions.

     Unless otherwise expressly provided pursuant to Section 301 with respect to
the Securities of any series, the provisions for subordination of the Securities
set forth in Article Sixteen hereof are hereby expressly made subject to the
provisions for satisfaction and discharge set forth in Section 401 hereof and
the provisions for defeasance and covenant defeasance set forth in Section 402
hereof and, anything herein to the contrary notwithstanding, upon the
effectiveness of such satisfaction and discharge pursuant to Section 401 or any
such defeasance or covenant defeasance pursuant to Section 402 with respect to
the Securities of any series, such Securities shall thereupon cease to be so
subordinated and shall no longer be subject to the provisions of Article Sixteen
hereof and, without limitation to the foregoing, all moneys, Government
Obligations and other securities or property deposited with the Trustee (or
other qualifying trustee) in trust in connection with such satisfaction and
discharge, defeasance or covenant defeasance, as the case may be, and all
proceeds therefrom may be applied to pay the principal of, premium, if any, and
interest, if any, on, and Additional Amounts, if any, with respect to the
Securities of such series as and when the same shall become due and payable
notwithstanding the provisions of Article Sixteen.

provision, when and as due by the terms of a Security of such series; or

the Company in this Indenture or any Security of such series (other than a
covenant or warranty for which the consequences of breach or nonperformance are
addressed elsewhere in this Section 501 or in the Securities or in a covenant or
warranty which has expressly been included in this Indenture or a Security of
that series, whether or not by means of a Supplemental Indenture, solely for the
benefit of Securities of a series other than such series), and continuance of
such default or breach for a period of 90 days after there has been given, by
registered or certified mail, to the Company by the Trustee or to the Company

Outstanding Securities of such series a written notice specifying such default
or breach and requiring it to be remedied and stating that such notice is a

          an involuntary case or proceeding or the commencement of any case
          against it;

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

                                       41
<PAGE>

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 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

     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

          (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 606; 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,

                                       42
<PAGE>

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 606.

     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 or any other obligor upon such Securities and any Coupons
appertaining thereto and collect the monies adjudged or decreed to be payable in
the manner provided by law out of the property of the Company or any other
obligor upon such Securities and any Coupons appertaining thereto, 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 any other obligor upon the
Securities or the property of the Company or such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of 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

                                       43
<PAGE>

          (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 606.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder 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.

Coupons, or both, as the case may be, and the notation thereon of the payment if

     amounts due and payable on such Securities and Coupons for principal and
     any premium, interest and Additional Amounts, respectively;

     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 reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;

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

          (5)  no direction inconsistent with such written request has been
     given to the Trustee during such 60-day period by the Holders of a majority
     in principal amount of the Outstanding Securities of 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
enforce any right under this Indenture, except in the manner herein provided and
for the equal and ratable benefit of all such Holders.

                   Premium, Interest and Additional Amounts.

     Notwithstanding any other provision in this Indenture, the Holder of any

and 307) interest on, and any Additional Amounts with respect

                                       45
<PAGE>

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, 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.

     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

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.

     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.

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,

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

     other Holders of Securities of such series not joining in such action.

     Section 513.  Waiver of Past Defaults.

          (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.

     Section 515.  Undertaking for Costs.

     All parties to this Indenture agree, and each Holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken 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; but the provisions
of this Section 515 shall not apply to any suit instituted by the Trustee, to
any suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of 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.

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,

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, (2) 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 (3) 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

                                       53
<PAGE>

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 606.

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

     Any Corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any Corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
Corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
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 611.  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

                                       54
<PAGE>

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, 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 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.

                                       55
<PAGE>

     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 606.

     The provisions of Sections 308, 603 and 604 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.

               __________________________________,
               As Trustee

               By:_______________________________________________________
                              As Authenticating Agent

               By:_______________________________________________________
                              Authorized Officer

     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.

     (3)  change any obligation of the Company to maintain an office or agency
in the places and for the purposes specified in Section 1002, or

     (4)  modify any of the provisions of Article Sixteen or the definition of
"Senior Indebtedness" in a manner adverse to the Holders of Securities, or

     (5)  modify any of the provisions of this Section or Section 513, except
to increase any such percentage or to provide that certain other provisions of
this Indenture cannot be modified or waived without the consent of the Holder of
each Outstanding Security affected thereby, or

     (6)  make any change that adversely affects the right to convert or
exchange any Security for Common Stock or other securities in accordance with
its terms.

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

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

     Section 903.  Execution of Supplemental Indentures.

     As a condition to executing, or accepting the additional trusts created by,
any supplemental indenture permitted by this Article or the modifications
thereby of the trust created by this Indenture, the Trustee shall be entitled to
receive, and (subject to Section 315 of the Trust Indenture Act) shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

     Section 904.  Effect of Supplemental Indentures.

     Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of a Security theretofore or thereafter authenticated and delivered hereunder
and of any Coupon appertaining thereto shall be bound thereby.

     Section 905.  Reference in Securities to Supplemental Indentures.

     Securities of any series authenticated and delivered after the execution of
any supplemental indenture pursuant to this Article may, and shall if required
by the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the

                                       62
<PAGE>

Company shall so determine, new Securities of any series so modified as to
conform, in the opinion of the Trustee and the Company, to any such supplemental
indenture may be prepared and executed by the Company and authenticated and
delivered by the Trustee in exchange for Outstanding Securities of such series.

     Section 906.   Effect on Senior Indebtedness.

     No supplement indenture shall directly or indirectly modify or eliminate
the provisions of Article Sixteen or the definition of "Senior Indebtedness" in
any manner which might terminate or impair the subordination of the Securities
to Senior Indebtedness without the prior written consent of the Holders of the
Senior Indebtedness.

     Section 907.   Conformity with Trust Indenture Act.

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

                                  ARTICLE TEN
                                   COVENANTS

     Section 1001.  Payment of Principal, Any Premium, Interest and Additional
                    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
on or before the Maturity thereof, and any Additional Amounts payable with
respect to such interest, shall be payable only upon presentation and surrender
of the Coupons appertaining thereto for such interest as they severally mature.

     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

                                       63
<PAGE>

Securities of such series are listed on The 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
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

                                       64
<PAGE>

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 (or any other
obligor upon the Securities of such series) 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 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

                                       65
<PAGE>

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 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

                                       66
<PAGE>

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.

                                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.

                                       67
<PAGE>

     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 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:

                                       68
<PAGE>

     (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 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 or the Cedel reference numbers of
such Securities, if any (or any other numbers used by a Depository to identify
such Securities).

                                       69
<PAGE>

     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 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

                                       70
<PAGE>

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 U.S. Depository
or other 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.

                                ARTICLE TWELVE
                                 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

                                       71
<PAGE>

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), 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 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

                                       72

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
specify in a written notice to the Trustee or, in the absence of such written
notice, as the Trustee may determine.

                       MEETINGS OF HOLDERS OF SECURITIES

     Section 1501.  Purposes for Which Meetings May be Called.

     A meeting of Holders of Securities of any series may be called at any time
and from time to time pursuant to this Article to make, give or take any

provided by this Indenture to be made, given or taken by Holders of Securities
of such 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 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 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 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, in the manner
provided in Section 106, not less than 21 nor more than 180 days prior to the

or the Holders of at least 10% in principal amount of the Outstanding Securities
of any series shall have requested the Trustee to call a meeting of the Holders
of Securities of such 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 series are
to be issued as Bearer Securities, in London for such meeting and may call such

     Section 1504.  Quorum; Action.

     The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for a meeting of
Holders of Securities of such series; provided, however, that 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 a
series, the Persons holding or representing such specified percentage in
principal amount of the Outstanding Securities of such 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 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 less than 10 days as determined by the chairman of the
meeting prior to the adjournment of such adjourned meeting. Notice of the
reconvening of any adjourned meeting shall be given as provided in Section
1502(1), except that such notice need be given only once not less than five days
prior to the date on which the meeting is scheduled to be reconvened. Notice of
the reconvening of an adjourned meeting shall state expressly the percentage, as
provided above, of the principal amount of the Outstanding Securities of such
series which shall constitute a quorum.

     Except as limited by the proviso to 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 principal amount of the Outstanding Securities of that series;
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 Securities of a series may be adopted at a
meeting or an adjourned meeting duly convened and at which a quorum is present
as aforesaid only by the affirmative vote of the Holders holding or representing
such specified percentage in principal amount of the Outstanding Securities of
that series; and provided, further, that, except as limited by the proviso to
Section 902, any resolution with respect to any request, demand, authorization,
direction, notice, consent, waiver or other Act which this Indenture expressly
provides may be made, given or taken by the Holders of a specified percentage,
which is less than a majority, in principal amount of the Outstanding Securities
of a series may be adopted at a meeting or an adjourned meeting duly 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 such series.

     Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities

                                       75
<PAGE>

of such 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 such 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 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 series represented at the meeting.

     (3)  At any meeting, each Holder of a Security of such series or proxy
shall be entitled to one vote for each $1,000 principal amount of Securities of
such 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 series or proxy.

     (4)  Any meeting of Holders of Securities of any 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 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 series shall be by written ballots on which shall be
subscribed the signatures of the Holders of

                                       76
<PAGE>

Securities of such series or of their representatives by proxy and the principal
amounts and serial numbers of the Outstanding Securities of such 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 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
                          SUBORDINATION OF SECURITIES

     Section 1601.  Agreement to Subordinate.

     The Company, for itself, its successors and assigns, covenants and agrees,
and each Holder of Securities by his acceptance thereof, likewise covenants and
agrees, that the payment of the principal of (and premium, if any) and interest,
if any, on, and Additional Amounts, if any, in respect of each and all of the
Securities is hereby expressly subordinated, to the extent and in the manner
hereinafter set forth, in right of payment to the prior payment in full of all
Senior Indebtedness.

     Section 1602.  Distribution on Dissolution, Liquidation and Reorganization;
                    Subrogation of Securities.

     Upon any distribution of assets of the Company upon any dissolution,
winding up, liquidation or reorganization of the Company, whether in bankruptcy,
insolvency, reorganization or receivership proceedings or upon an assignment for
the benefit of creditors or any other marshalling of the assets and liabilities
of the Company or otherwise (subject to the power of a court of competent
jurisdiction to make other equitable provision reflecting the rights conferred
in this Indenture upon the Senior Indebtedness and the holders thereof with
respect to the Securities and the holders thereof by a lawful plan of
reorganization under applicable bankruptcy law):

          (a)  the holders of all Senior Indebtedness shall be entitled to
receive payment in full of the principal thereof (and premium, if any) and
interest due thereon before the Holders of the Securities are entitled to
receive any payment upon the principal (or premium, if any) or

                                       77
<PAGE>

interest, if any, on, or Additional Amounts, if any, in respect of the
indebtedness evidenced by the Securities; and

          (b)  any payment or distribution of assets of the Company of any kind
or character, whether in cash, property or securities, to which the Holders of
the Securities or the Trustee would be entitled except for the provisions of
this Article Sixteen shall be paid by the liquidating trustee or agent or other
person making such payment or distribution, whether a trustee in bankruptcy, a
receiver or liquidating trustee or otherwise, directly to the holders of Senior
Indebtedness or their representative or representatives or to the trustee or
trustees under any indenture under which any instruments evidencing any of such
Senior Indebtedness may have been issued, ratably according to the aggregate
amounts remaining unpaid on account of the principal of (and premium, if any)
and interest on the Senior Indebtedness held or represented by each, to the
extent necessary to make payment in full of all Senior Indebtedness remaining
unpaid, after giving effect to any concurrent payment or distribution to the
holders of such Senior Indebtedness; and

          (c)  in the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, shall be received by the Trustee or the Holders of the
Securities before all Senior Indebtedness is paid in full, such payment or
distribution shall be paid over, upon written notice to the Trustee, to the
holders of such Senior Indebtedness or their representative or representatives
or to the trustee or trustees under any indenture under which any instrument
evidencing any of such Senior Indebtedness may have been issued, ratably as
aforesaid, for application to payment of all Senior Indebtedness remaining
unpaid until all such Senior Indebtedness shall have been paid in full, after
giving effect to any concurrent payment or distribution to the holders of such
Senior Indebtedness.

     Subject to the payment in full of all Senior Indebtedness, the Holders of
the Securities shall be subrogated to the rights of the holders of Senior
Indebtedness to receive payments or distributions of cash, property or
securities of the Company applicable to Senior Indebtedness until the principal
of (and premium, if any) and interest, if any, on, or Additional Amounts, if
any, in respect of the Securities shall be paid in full and no such payments or
distributions to the Holders of the Securities of cash, property or securities
otherwise distributable to the holders of Senior Indebtedness shall, as between
the Company, its creditors other than the holders of Senior Indebtedness, and
the Holders of the Securities be deemed to be a payment by the Company on
account of the Securities. It is understood that the provisions of this Article
Sixteen are and are intended solely for the purpose of defining the relative
rights of the Holders of the Securities, on the one hand, and the holders of the
Senior Indebtedness, on the other hand. Nothing contained in this Article
Sixteen or elsewhere in this Indenture or in the Securities is intended to or
shall impair, as between the Company, its creditors other than the holders of
Senior Indebtedness, and the Holders of the Securities, the obligation of the
Company, which is unconditional and absolute, to pay to the Holders of the
Securities the principal of (and premium, if any) and interest, if any, on, or
Additional Amounts, if any, in respect of the Securities as and when the

                                       78
<PAGE>

same shall become due and payable in accordance with their terms, or to affect
the relative rights of the Holders of the Securities and creditors of the
Company other than the holders of Senior Indebtedness, nor shall anything herein
or in the Securities prevent the Trustee or the Holder of any Security from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, under this Article Sixteen of the
holders of Senior Indebtedness in respect of cash, property or securities of the
Company received upon the exercise of any such remedy. Upon any payment or
distribution of assets of the Company referred to in this Article Sixteen, the
Trustee, subject to the provisions of Section 601, shall be entitled to rely
upon a certificate of the liquidating trustee or agent or other person making
any distribution to the Trustee for the purpose of ascertaining the Persons
entitled to participate in such distribution, the holders of Senior Indebtedness
and other indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article Sixteen.

     The Trustee, however, shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness. The Trustee shall not be liable to any such
holder if it shall pay over or distribute to or on behalf of Holders of
Securities or the Company moneys or assets to which any holder of Senior
Indebtedness shall be entitled by virtue of this Article Sixteen.

     If the Trustee or any Holder of Securities does not file a proper claim or
proof of debt in the form required in any proceeding referred to above prior to
30 days before the expiration of the time to file such claim in such proceeding,
then the holder of any Senior Indebtedness is hereby authorized, and has the
right, to file an appropriate claim or claims for or on behalf of such Holder of
Securities.

     Section 1603.  No Payment on Securities in Event of Default on Senior
                    Indebtedness.

     No payment by the Company on account of principal (or premium, if any),
sinking funds or interest, if any, on, or Additional Amounts, if any, in respect
of the Securities shall be made unless full payment of amounts then due for the
principal of (and premium, if any), sinking funds and interest, if any, on
Senior Indebtedness has been made or duly provided for in money or money's
worth.

     Section 1604.  Payments on Securities Permitted.

     Nothing contained in this Indenture or in any of the Securities shall (a)
affect the obligation of the Company to make, or prevent the Company from
making, at any time except as provided in Sections 1602 and 1603, payments of
principal of (or premium, if any) or interest, if any, on, or Additional Amounts
or sinking fund payments, if any, with respect to the Securities or (b) prevent
the application by the Trustee of any moneys deposited with it hereunder to the
payment of or on account of the principal of (or premium, if any) or interest,
if any, on, or Additional Amounts, if any, in respect of the Securities, unless
the Trustee shall have received at

                                       79
<PAGE>

its Corporate Trust Office written notice of any event prohibiting the making of
such payment more than two Business Days prior to the date fixed for such
payment.

     Section 1605.  Authorization of Holders to Trustee to Effect Subordination.

     Each Holder of Securities by his acceptance thereof authorizes and directs
the Trustee on his behalf to take such action as may be necessary or appropriate
to effectuate the subordination as provided in this Article Sixteen and appoints
the Trustee his attorney-in-fact for any and all such purposes.

     Section 1606.  Notices to Trustee.

     The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities pursuant to this Article Sixteen. Failure
to give such notice shall not affect the subordination of the Securities to
Senior Indebtedness. Notwithstanding the provisions of this Article Sixteen or
any other provisions of this Indenture, neither the Trustee nor any Paying Agent
(other than the Company) shall be charged with knowledge of the existence of any
Senior Indebtedness or of any event which would prohibit the making of any
payment of moneys to or by the Trustee or such Paying Agent, unless and until
the Trustee or such Paying Agent shall have received (in the case of the
Trustee, at its Corporate Trust Office) written notice thereof from the Company
or from the holder of any Senior Indebtedness or from the trustee for any such
holder, together with proof satisfactory to the Trustee of such holding of
Senior Indebtedness or of the authority of such trustee; provided, however, that
if at least two Business Days prior to the date upon which by the terms hereof
any such moneys may become payable for any purpose (including, without
limitation, the payment of either the principal of (or premium, if any) or
interest, if any, on, or Additional Amounts, if any, in respect of any Security)
the Trustee shall not have received with respect to such moneys the notice
provided for in this Section 1606, then, anything herein contained to the
contrary notwithstanding, the Trustee shall have full power and authority to
receive such moneys and to apply the same to the purpose for which they were
received, and shall not be affected by any notice to the contrary, which may be
received by it less than two Business Days prior to such date. The Trustee shall
be entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Indebtedness (or a trustee on
behalf of such holder) to establish that such a notice has been given by a
holder of Senior Indebtedness or a trustee on behalf of any such holder. In the
event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior
Indebtedness (or a trustee on behalf of such holder) to participate in any
payment or distribution pursuant to this Article Sixteen, the Trustee may
request such Person to furnish evidence to the reasonable satisfaction of the
Trustee as to the amount of Senior Indebtedness held by such Person (or the
amount of Senior Indebtedness as to which such Person is trustee), the extent to
which such Person is entitled to participate in such payment or distribution and
any other facts pertinent to the rights of such Person under this Article
Sixteen

                                       80
<PAGE>

and, if such evidence is not furnished, the Trustee may defer any payment to
such Person pending judicial determination as to the right of such Person to
receive such payment.

     Section 1607.  Trustee as Holder of Senior Indebtedness.

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

     Nothing in this Article Sixteen shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 606.

     Section 1608.  Modifications of Terms of Senior Indebtedness.

     Any renewal or extension of the time of payment of any Senior Indebtedness
or the exercise by the holders of Senior Indebtedness of any of their rights
under any instrument creating or evidencing Senior Indebtedness, including,
without limitation, the waiver of default thereunder, may be made or done all
without notice to or assent from the Holders of the Securities or the Trustee.

     No compromise, alteration, amendment, modification, extension, renewal or
other change of, or waiver, consent or other action in respect of, any liability
or obligation under or in respect of, or of any of the terms, covenants or
conditions of any indenture or other instrument under which any Senior
Indebtedness is outstanding or of such Senior Indebtedness, whether or not such
release is in accordance with the provisions of any applicable document, shall
in any way alter or affect any of the provisions of this Article Sixteen or of
the Securities relating to the subordination thereof.

     Section 1609.  Reliance on Judicial Order or Certificate of Liquidating
Agent.

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

___________, 20__," in the initial aggregate principal amount of $__________,
which amount shall be as set forth in any written orders of the Company for the
authentication and delivery of Subordinated Debentures pursuant to Section 302
of the Base Indenture and Section 7.1 hereof. Additional Subordinated Debentures
without limitation as to amount, and without the consent of the holders of the
then Outstanding Subordinated Debentures, may also be authenticated and
delivered in the manner provided in Section 302 of the Base Indenture. Any such
additional Subordinated Debentures will have the same Stated Maturity and other
terms as those initially issued.

     2.2  Stated Maturity. The Stated Maturity of the Subordinated Debentures is
___________, 20__, which may not be shortened or extended.

     2.3  Form and Payment; Minimum Transfer Restriction.

          (a) The Subordinated Debentures shall be issued to the [holders]

office of the Trustee; provided, however, that payment of interest may be made
at the option of the Company by check mailed to the registered holder at such
address as shall appear in the Register. [Notwithstanding the foregoing, so long
as the registered holder of any Subordinated Debentures is the Property Trustee,
the payment of the principal of and interest (including Additional Interest and
Additional Tax Sums, if any) on such Subordinated Debentures held by the
Property Trustee will be made at such place, or by wire transfer of immediately
available funds to such account, as may be designated by the Property Trustee.]
The Register for the Subordinated Debentures shall be kept at the principal
office of the Trustee and the Trustee is hereby appointed registrar for the
Subordinated Debentures.

          (b) The Subordinated Debentures may be transferred or exchanged only
in minimum denominations of $____ and integral multiples of $____ in excess
thereof, and any attempted transfer, sale or other disposition of Subordinated
Debentures in a denomination of less than $____ shall be deemed to be void and
of no legal effect whatsoever. Any such transferee shall be deemed not to be the
holder of such Subordinated Debentures for any purpose, including but not
limited to the receipt of payments in respect of such Subordinated Debentures

                                       6
<PAGE>

and such transferee shall be deemed to have no interest whatsoever in such
Subordinated Debentures.

     2.4  Exchange and Registration of Transfer of Subordinated Debentures;
Restrictions on Transfers; Depositary. [If distributed to holders of Trust
Preferred Securities pursuant to Section 8.2 of the Trust Agreement, the
Subordinated Debentures will be issued to such holders in the same form as the
Trust Preferred Securities that such Subordinated Debentures replace in
accordance with the following procedures:]

          (a) So long as Subordinated Debentures are eligible for book-entry
settlement with the Depositary, or unless required by law, all Subordinated
Debentures that are so eligible will be represented by one or more Subordinated
Debentures in global form (a "Global Debenture") registered in the name of the
Depositary or the nominee of the Depositary. Except as provided in Section
2.4(c) below, beneficial owners of a Global Debenture shall not be entitled to
have Definitive Debenture Certificates registered in their names, will not
receive or be entitled to receive physical delivery of Definitive Debenture
Certificates and will not be registered holders of such Global Debentures.

          (b) The transfer and exchange of beneficial interests in Global
Debentures shall be effected through the Depositary in accordance with the
Indenture and the procedures and standing instructions of the Depositary and the
Trustee shall make appropriate adjustments on its books and records to reflect
increases or decreases in principal amounts of such Global Debentures.

          (c) Notwithstanding any other provisions of the Indenture (other than
the provisions set forth in this Section 2.4(c)), a Global Debenture may not be
exchanged in whole or in part for Subordinated Debentures registered, and no
transfer of a Global Debenture may be registered, in the name of any person
other than the Depositary or a nominee thereof unless (i) such Depositary (A)
has notified the Company that it is unwilling or unable to continue as
Depositary for such Global Debenture or (B) has ceased to be a clearing agency
registered as such under the Exchange Act and no successor Depositary has been
appointed by the Company within 90 days after its receipt of such notice or its
becoming aware of such ineligibility, (ii) there shall have occurred and be
continuing an Event of Default, or any event which after notice or lapse of time
or both would be an Event of Default under the Indenture, with respect to such
Debenture, or (iii) the Company, in its sole discretion, instructs the Trustee
to exchange such Global Debenture for a Subordinated Debenture that is not a
Global Debenture (in which case such exchange shall be effected by the Trustee).

          The Depositary shall be a clearing agency registered under the
Exchange Act. The Company initially appoints The Depository Trust Company to act
as Depositary with respect to the Global Debentures. Initially, any Global
Debentures shall be registered in the name of Cede & Co., as the nominee of the
Depositary, and deposited with the Trustee as custodian for Cede & Co.

          Definitive Subordinated Debentures issued in exchange for all or a
part of a Global Debenture pursuant to this Section 2.4(c) shall be registered
in such names and in such authorized denominations as the Depositary, pursuant
to instructions from its direct or indirect

                                       7
<PAGE>

participants or otherwise, shall instruct the Trustee. Upon execution and
authentication, the Trustee shall deliver such definitive Subordinated
Debentures to the person in whose names such definitive Subordinated Debentures
are so registered.

          So long as Subordinated Debentures are represented by one or more
Global Debentures, (i) the registrar for the Subordinated Debentures and the
Trustee shall be entitled to deal with the clearing agency for all purposes of
the Indenture relating to such Global Debentures as the sole holder of the
Subordinated Debentures evidenced by such Global Debentures and shall have no
obligations to the holders of beneficial interests in such Global Debentures;
and (ii) the rights of the holders of beneficial interests in such Global
Debentures shall be exercised only through the clearing agency and shall be
limited to those established by law and agreements between such holders and the
clearing agency and/or the participants in the clearing agency.

          At such time as all interests in a Global Debenture have been paid,
redeemed, exchanged, repurchased or canceled, such Global Debenture shall be,
upon receipt thereof, canceled by the Trustee in accordance with standing
procedures and instructions of the Depositary. At any time prior to such
cancellation, if any interest in a Global Debenture is exchanged for definitive
Subordinated Debentures, redeemed by the Company pursuant to Article 3 or
canceled, or transferred for part of a Global Debenture, the principal amount of
such Global Debenture shall, in accordance with the standing procedures and
instructions of the Depositary be reduced or increased, as the case may be, and
an adjustment on the books and records of the Trustee shall be made with respect
to such Global Debenture by, or at the direction of, the Trustee to reflect such
reduction or increase.

     2.5  Interest.

          (a) Each Subordinated Debenture will bear interest at the rate of ___%
per annum (the "Coupon Rate") from ___________, 20__ until the principal thereof
becomes due and payable, and will bear interest on any overdue principal at the
Coupon Rate and (to the extent that payment of such interest is enforceable
under applicable law) on any overdue installment of interest at the Coupon Rate
("Additional Interest"), compounded semi-annually, payable (subject to the
provisions of Article 4) semi-annually in arrears on the 15th day of [January
and July] of each year (each, an "Interest Payment Date"), commencing on ______
15, 20__ to the Person in whose name such Subordinated Debenture is registered,
subject to certain exceptions, at the close of business on the Record Date next
preceding such Interest Payment Date. The "Regular Record Date" for payment of
interest will be the Business Day next preceding the Interest Payment Date,
unless such Subordinated Debenture is registered to a holder other than [the
Property Trustee or] a nominee of the Depositary, in which case the Record Date
for payment of interest will be the fifteenth calendar day preceding the
applicable Interest Payment Date, whether or not a Business Day. [Until
liquidation, if any, of the Trust, each Subordinated Debenture will be held in
the name of the Property Trustee in trust for the benefit of the holders of the
Trust Securities.]

          (b) The amount of interest payable for any period will be computed on
the basis of a [360-day year of twelve 30-day months]. In the event that any
date on which interest is payable on the Subordinated Debentures is not a
Business Day, then payment of interest

                                       8
<PAGE>

payable on such date will be made on the next succeeding day which is a Business
Day (and without any interest or other payment in respect of any such delay),
except that, if such Business Day is in the next succeeding calendar year, such
payment shall be made on the next preceding day which is a Business Day, in each
case with the same force and effect as if made on the date such payment was
originally payable.

          (c) [The Company will also pay any Additional Tax Sums as additional
distributions on the Subordinated Debentures if the Trust is required to pay any
additional taxes, duties or other governmental charges as a result of a Tax
Event.]

     2.6  [Direct Action. In addition to any right of Direct Action granted
under Section 3.8 of the Trust Agreement to the holders of Trust Preferred
Securities, if the Property Trustee fails to enforce its rights under the Trust
Agreement or the Indenture to the fullest extent permitted by law and subject to
the terms of the Trust Agreement and the Indenture, then a holder of Trust
Preferred Securities may directly institute a proceeding against the Company to
enforce the Property Trustee's rights under the Trust Agreement or the Indenture
without first instituting a legal proceeding against the Property Trustee or any
other person.]

                                   ARTICLE IV
                     [EXTENSION OF INTEREST PAYMENT PERIOD

     4.1  Extension of Interest Payment Period. So long as no Event of Default
under Section 501 of the Base Indenture has occurred and is continuing, the
Company shall have the right at any time during the term of the Subordinated
Debentures, from time to time to defer the payment of interest by extending the
interest payment period of such Subordinated Debentures for a period not
exceeding 10 consecutive semi-annual periods (an "Extension Period"), during
which Extension Period the Company shall [not] have the right to make partial
payments of interest. No Extension Period shall end on a date other than an
Interest Payment Date or extend beyond the Stated Maturity of the Subordinated
Debentures. To the extent permitted by applicable law, interest, the payment of
which has been deferred because of an Extension Period imposed pursuant to this
Section 4.1, will bear Additional Interest compounded semi-annually. At the end
of the Extension Period, the Company shall pay all interest then accrued and
unpaid on the Subordinated Debentures, including any Additional Interest and
Additional Tax Sums, if applicable, to the holders of the Subordinated
Debentures in whose names the Subordinated Debentures are registered in the
Register on the first Record Date preceding the end of the Extension Period.
Before the termination of any Extension Period, the Company may further extend
such Extension Period, provided that such period together with all such further
extensions thereof shall not exceed 10 consecutive semi-annual periods, or
extend beyond the Stated Maturity. At any time following the termination of any
Extension Period and upon the payment of any accrued and unpaid Additional
Interest and Additional Tax Sums, if applicable, then due, the Company may elect
to begin a new Extension Period, subject to the foregoing requirements. No
interest shall be due and payable during an Extension Period, except at the end
thereof.

          During any such Extension Period, the Company shall not (i) declare or
pay any dividends or distributions on, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of the Company's "Capital Stock" (which
shall include Common Stock and the Company's preferred stock) or (ii) make any
payment of principal of or interest on or repay, repurchase or redeem any debt
securities of the Company that rank on a parity with or junior to the
Subordinated Debentures or make any guarantee payments with respect to any [CSX
Guarantee or other] guarantee by the Company of the debt securities of any
Subsidiary of the Company that by its terms ranks on a parity with or junior to
the Subordinated Debentures (other than (a) dividends or distributions in Common
Stock, (b) any declaration of a dividend in connection with the implementation
of a Rights Plan, the issuance of any Capital Stock or any class or series of
preferred stock of the Company under any Rights Plan or the redemption or
repurchase of any rights distributed pursuant to a Rights Plan, [(c) payments
under any CSX

(d) purchases of Common Stock related to the issuance of Common Stock or rights
under any of the Company's benefit plans for its directors, officers, employees,
consultants or advisors).

     4.2  Notice of Extension.

          (a) If the Property Trustee is the only registered holder of the
Subordinated Debentures at the time the Company elects to begin or extend an
Extension Period, the Company shall give written notice to the Property Trustee,
the Administrative Trustees and the Trustee of its election to begin or extend
any Extension Period at least five Business Days prior to the earlier of (i) the
next succeeding date on which Distributions on the Trust Preferred Securities
issued by the Trust would have been payable but for the election to begin or
extend such Extension Period or (ii) subject to applicable principles of federal
securities law, the date the Administrative Trustees are required to give notice
to any securities exchange or other applicable self-regulatory organization or
to holders of such Trust Preferred Securities of the record date or the date
such Distributions are payable, but in any event not less than five Business
Days prior to such record date. An Administrative Trustee shall give notice of
the Company's election to begin or extend an Extension Period to the holders of
such Trust Preferred Securities.

          (b) If the Property Trustee is not the only holder of the Subordinated
Debentures at the time the Company elects to begin or extend an Extension
Period, the Company shall give the holders of the Subordinated Debentures, the
Administrative Trustees and the Trustee written notice of its election to begin
or extend such Extension Period at least 10 Business Days prior to the earlier
of (i) the next succeeding Interest Payment Date or (ii) subject to applicable
principles of federal securities law, the date the Company is required to give
notice of the record or payment date of such interest payment to any applicable
self-regulatory organization or to holders of the Subordinated Debentures.

          (c) The semi-annual period in which any notice is given pursuant to
paragraphs (a) or (b) of this Section 4.2 shall be counted as one of the 10
consecutive semi-annual periods permitted in the maximum Extension Period
permitted under Section 4.1.]

Agreement, the Company shall pay to the Trust (and any permitted successor or

such additional amounts as may be necessary in order that the amount of
Distributions then due and payable by the Trust on the Preferred Securities and
Common Securities that at any time remain outstanding in accordance with the
terms thereof shall not be reduced as a result of any additional taxes, duties
and other governmental charges to which the Trust has become subject as a result

Tax Sums provided for in this paragraph to the extent that, in such context,
Additional Tax Sums are, were or would be payable in respect thereof pursuant to
the provisions of this Section 8.1 and express reference to the payment of
Additional Tax Sums (if applicable) in any provisions hereof shall not be
construed as excluding Additional Tax Sums in those provisions hereof where such
express reference is not made; provided, however, that the deferral of the
payment of interest pursuant to this Section 8.1 or the Subordinated Debentures
shall not defer the payment of any Additional Tax Sums that may be then due and
payable.

guarantee payments with respect to any [CSX Guarantee or other ]guarantee by the
Company of debt securities of any Subsidiary that by its terms ranks on a parity
with or junior to the Subordinated Debentures (other than (a) dividends or
distributions in Common Stock; (b) any declaration of a dividend in connection
with the implementation of a Rights Plan, the issuance of any Capital Stock of
any class or series of preferred stock of the Company under any Rights Plan or
the redemption or repurchase of any rights distributed pursuant to a Rights
Plan; (c) [payments under the CSX Guarantee relating to the Preferred Securities
issued by the Trust; and (d)] purchases of Common Stock related to the issuance
of Common Stock or rights under any of the Company's benefit plans for its

the giving of notice or the lapse of time or both, would constitute an Event of
Default hereunder and (b) in respect of which the Company shall not have taken
reasonable steps to cure, (ii) the Company shall be in default with respect to
its payment of any obligations under the CSX Guarantee or (iii) the Company
shall have given notice of its election to begin an Extension Period as provided

such Common Securities, (ii) not to voluntarily terminate, wind up or liquidate
the Trust, except (a) in connection with a prepayment in full of the
Subordinated Debentures or a distribution of the Subordinated Debentures to the
holders of Preferred Securities in liquidation of the Trust or (b) in connection
with certain mergers, consolidations or amalgamations permitted by the relevant
Trust Agreement and (iii) to use its reasonable efforts, consistent with the
terms and provisions of such Trust Agreement, to cause the Trust to remain
classified as a grantor trust and not an association taxable as a corporation
for United States federal income tax purposes.]

     The interest so payable will, subject to certain exceptions provided in the
Indenture hereinafter referred to, be paid to the person in whose name this
Debenture is registered at the close of business on the Record Date next
preceding such Interest Payment Date. The Record Date shall be the Business Day
next preceding the Interest Payment Date, unless this Debenture is registered to
a holder other than [the Property Trustee or] a nominee of The Depository Trust
Company, in which case the Record Date will be the fifteenth calendar day
preceding such Interest Payment Date whether or not a Business Day. This
Debenture may be presented for payment of principal and interest at the
principal corporate trust office of The Chase Manhattan Bank, as paying agent
for the Company, maintained for that purpose in the Borough of Manhattan, The
City of New York; provided, however, that payment of interest may be made at the
option of the Company (i) by check mailed to such address of the person entitled
thereto as the address shall appear on the Register of the Debentures or (ii) by
transfer to an account maintained by the Person entitled thereto as specified in
the Register, provided that proper transfer instructions have been received by
the Record Date. Interest on the Debenture will be computed on the basis of a
[360-day year of twelve 30-day months].

     [So long as no Event of Default has occurred and is continuing, the Company
shall have the right, at any time during the term of this Debenture, from time
to time to defer the payment of interest by extending the interest payment
period of this Debenture for a period not exceeding 10 consecutive semi-annual
periods (an "Extension Period"), during which Extension Period the Company shall
[not] have the right to make partial payments of interest. No Extension Period
shall end on a date other than an Interest Payment Date or extend beyond the
Stated Maturity of this Debenture.  To the extent permitted by applicable law,
interest, the payment of which has been deferred because of an Extension Period,
will bear Additional Interest compounded semi-annually.  At the end of the
Extension Period, the Company shall pay all interest then accrued and unpaid on
this Debenture, including any Additional Interest and Additional Tax Sums, if
applicable, to the Person in whose name this Debenture is registered in the
Register on the first Record Date preceding the end of the Extension Period.
Before the termination of any Extension Period, the Company may further extend
such Extension Period, provided that such period together with all such further
extensions thereof shall not exceed 10 consecutive semi-annual periods, or
extend beyond the Stated Maturity. At any time following the termination of any
Extension Period and upon the payment of any accrued and unpaid Additional
Interest and Additional Tax Sums, if applicable, then due, the Company may elect
to begin a new Extension Period, subject to the foregoing requirements. No
interest shall be due and payable during an Extension Period, except at the end
thereof.]

     [During any such Extension Period, the Company shall not (i) declare or pay
any dividends or distributions on, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of the Company's Capital Stock or (ii)
make any payment of principal of or interest on or repay, repurchase or redeem
any debt securities of the Company that rank on a parity with or junior to this
Debenture or make any guarantee payments with respect to any [CSX Guarantee or
other] guarantee by the Company of the debt securities of any Subsidiary of the
Company that by its terms ranks on a parity with or junior to this Debenture
(other than (a) dividends or distributions in Common Stock, (b) any declaration
of a dividend in connection with the implementation of a Rights Plan, the
issuance of any Capital Stock or any class or series of preferred stock of the
Company under any Rights Plan or the redemption or repurchase of any rights
distributed pursuant to a Rights Plan, [(c) payments under the CSX Guarantee
relating to

                                      A-3

the Trust Preferred Securities issued by the Trust,] and (d) purchases of Common
Stock related to the issuance of Common Stock or rights under any of the
Company's benefit plans for its directors, officers, employees, consultants or
advisors).]

     [If the Property Trustee is the only registered holder of the Debentures of
this series at the time the Company elects to begin or extend an Extension
Period, the Company shall give written notice to the Property Trustee, the
Administrative Trustees and the Trustee of its election to begin or extend any
Extension Period at least five Business Days prior to the earlier of (i) the
next succeeding date on which Distributions on the Trust Preferred Securities
issued by the Trust would have been payable but for the election to begin or
extend such Extension Period or (ii) subject to applicable principles of federal
securities law, the date the Administrative Trustees are required to give notice
to any securities exchange or other applicable self-regulatory organization or
to holders of such Trust Preferred Securities of the record date or the date
such Distributions are payable, but in any event not less than five Business
Days prior to such record date.]  [An Administrative Trustee shall give notice
of the Company's election to begin or extend an Extension Period to the holders
of such Trust Preferred Securities.]

     [If the Property Trustee is not the only holder of the Debentures of this
series at the time the Company elects to begin or extend an Extension Period,]
the Company shall give the holders of the Debentures of this series, the
Administrative Trustees and the Trustee written notice of its election to begin
or extend such Extension Period at least 10 Business Days prior to the earlier
of (i) the next succeeding Interest Payment Date or (ii) subject to applicable
principles of federal securities law, the date the Company is required to give
notice of the record or payment date of such interest payment to any applicable
self-regulatory organization or to holders of the Debentures of this series.

     The semi-annual period in which any notice is given pursuant to the two
preceding paragraphs shall be counted as one of the 10 consecutive semi-annual
periods permitted in the maximum Extension Period.
