to be given or taken by Holders of the Outstanding Securities of all series

direction, notice, consent, waiver or other action provided by 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

supplemental indenture with respect to such series, 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 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 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.

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

         (c)  The ownership of Registered Securities shall be proved by the 
Security Register.

         (d)  The ownership of Bearer Securities 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, wherever 
situated, if such certificate shall be deemed by the Trustee to be 
satisfactory, showing that at the date therein mentioned such Person had on 
deposit with such depositary, or exhibit, 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 Trustee to be satisfactory.  The Trustee and the Company may 
assume 


                                                                            13

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 of Bearer Securities may also be proved in any 
other manner which the Trustee deems sufficient.

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

         In the absence of any such record date fixed by the Company, 
regardless as to whether a solicitation of the Holders is occurring on behalf 
of the Company or any Holder, the Trustee may, at its option, fix in advance 
a record date for the determination of such Holders entitled to give such 
request, demand, authorization, direction, notice, consent, waiver or other 
Act, but the Trustee shall have no obligation to do so. Any such record date 
shall be a date not more than 30 days prior to the first solicitation of 
Holders generally in connection therewith no later than the date of such 
solicitation.

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


                                                                            14

notice of any event to Holders of Registered Securities by the Company or the 
Trustee, such notice shall be sufficiently given (unless otherwise herein 
expressly provided) if in writing and mailed, first-class postage prepaid, to 
each such Holder affected by such event, at his address as it appears in the 
Security Register, not later than the latest date, and not earlier than the 
earliest date, prescribed for the giving of such notice.  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 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 mailed to 
a Holder in the manner herein prescribed shall be conclusively deemed to have 
been received by such Holder, whether or not such Holder actually receives 
such notice.

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

         Except as otherwise expressly provided herein or otherwise specified 
with respect to any Securities pursuant to Section 3.1, where this Indenture 
provides for notice to Holders of Bearer Securities of any event, such notice 
shall be sufficiently given if published in an Authorized Newspaper in New 
York City and in such other city or cities as may be specified in such 
Securities on a Business Day, such publication to be not later than the 
latest date, and not earlier than the earliest date, prescribed for the 
giving of such notice.  Any such notice shall be deemed to have been given on 
the date of such publication or, if published more than once, on the date of 
the first such publication.


                                                                            15

         If 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 Bearer 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 the failure to 
give notice by publication to any particular Holder of Bearer Securities as 
provided above, nor any defect in any notice so published, shall affect the 
sufficiency of such notice with respect to other Holders of Bearer Securities 
or the sufficiency of any notice to Holders of Registered Securities given as 
provided herein.

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

         Where this Indenture provides for notice in any manner, such notice 
may be waived in writing by the Person entitled to receive such notice, 
either before or after the event, and such waiver shall be the equivalent of 
such notice.  Waivers of notice by Holders shall be filed with the Trustee, 
but such filing shall not be a condition precedent to the validity of any 
action taken in reliance upon such waiver.
 
    Section 1.7  Effect of Headings and Table of Contents.  The Article and 
Section headings herein and the Table of Contents are for convenience only 
and shall not affect the construction hereof.

    Section 1.8 Successors and Assigns.  All covenants and agreements in this 
Indenture by the Company shall bind its successors and assigns, whether so 
expressed or not.

    Section 1.9 Separability Clause.  In case any provision in this Indenture 
or in any Security or 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 1.10 Benefits of Indenture.  Nothing in this Indenture or in the 
Securities or coupons, express or implied, shall give to any Person, other 
than the parties hereto, any Security Registrar, any Paying Agent, any 
Authenticating Agent and their successors hereunder and the Holders any 
benefit or any legal or equitable right, remedy or claim under this Indenture.

    Section   1.11 Governing Law.  This Indenture and the Securities and 
coupons shall be governed by and construed in accordance with the law of the 
State of New York.  This Indenture is subject to the provisions of the TIA 
that are required to 


                                                                            16

be part of this Indenture and shall, to the extent applicable, be governed by 
such provisions.

    Section   1.12 Legal Holidays.  In any case where any Interest Payment 
Date, Redemption Date, Repayment Date, sinking fund payment date, Stated 
Maturity or Maturity of any Security shall not be a Business Day at any Place 
of Payment, then (notwithstanding any other provision of this Indenture or 
any Security or coupon other than a provision in the Securities of any series 
which specifically states that such provision shall apply in lieu hereof), 
payment of interest or any Additional Amounts or principal (and premium, if 
any) need not be made at such Place of Payment on such date, but may be made 
on the next succeeding Business Day at such Place of Payment with the same 
force and effect as if made on the Interest Payment Date, Redemption Date, 
Repayment Date or sinking fund payment date, or at the Stated Maturity or 
Maturity, provided that no interest shall accrue on the amount so payable for 
the period from and after such Interest Payment Date, Redemption Date, 
Repayment Date, sinking fund payment date, Stated Maturity or Maturity, as 
the case may be.

    Section   1.13 Personal Immunity from Liability for Incorporators, 
Stockholders, Etc.  No recourse shall be had for the payment of the principal 
of or premium, if any, or interest, if any, on any Security, or for any claim 
based thereon, or otherwise in respect of any Security, or based on or in 
respect of this Indenture or any indenture supplemental hereto, against any 
incorporator, or against any past, present or future stockholder, director of 
officers, as such, of the Company or of any successor corporation, whether by 
virtue of any constitution, statute or rule of law, or by the enforcement of 
any assessment or penalty or otherwise, all such liability being expressly 
waived and released as a condition of, and as consideration for, the 
execution of this Indenture and the issue of Securities.

may deem appropriate and as are not inconsistent with the provisions of this 
Indenture, or as may be required to comply with any law or 


                                                                            17

Securities shall have interest coupons attached.

         The definitive Securities and 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

                   By
                        Authorized Signatory

    Section 2.3 Securities Issuable in Global Form.  If Securities of or 
within a series are issuable in global form, as specified as contemplated by 
Section 3.1, then, notwithstanding clause (8) of Section 3.1 and the 
provisions of Section 3.2, any such Security shall represent such of the 
Outstanding Securities of such series as shall be specified therein and may 
provide that it shall represent the aggregate amount of Outstanding 
Securities of such series from time to time endorsed thereon and that the 
aggregate amount of Outstanding Securities of such series represented thereby 
may from time to time be increased or decreased to reflect exchanges.  Any 
endorsement of a Security in global form to reflect the amount, or any 
increase or decrease in the amount, of Outstanding Securities represented 
thereby shall be made by the Trustee in such manner and upon instructions 
given by such Person or Persons as shall be specified therein or in the 
Company Order to be delivered to the Trustee pursuant to Section 3.3 or 3.4.

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 3.3 or 3.4 has been, or simultaneously is, delivered, any 
instructions by the Company with respect to endorsement or delivery 


                                                                            18

comply with Section 1.2 and need not be accompanied by an Opinion of Counsel.
 
         The provisions of the last sentence of Section 3.3 shall apply to 
any Security represented by a Security in global form if such Security was 
never issued and sold by the Company and the Company delivers to the Trustee 
the Security in global form together with written instructions (which need 
not comply with Section 1.2 and need not be accompanied by an Opinion of 
Counsel) with regard to the reduction in the principal amount of Securities 
represented thereby, together with the written statement contemplated by the 
last sentence of Section 3.3.

         Notwithstanding the provisions of Section 3.7, unless otherwise 
specified as contemplated by Section 3.1, payment of principal of and any 
premium and interest on any Security in permanent global form shall be made 
to the Person or Persons specified therein.

         Notwithstanding the provisions of Section 3.8 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 permanent global Security (i) in the 
case of a permanent global Security in registered form, the Holder of such 
permanent global Security in registered form, or (ii) in the case of a 
permanent global Security in bearer form, Euroclear or CEDEL.

    for Registered Securities of the series and vice versa (if permitted by
    applicable laws and regulations), whether any Securities of the series are
    to be issuable     initially in temporary global form and whether any
    Securities of the series are to be issuable in permanent global form with

    any such permanent global Security may exchange such interests for
    Securities of such series and of like tenor of any authorized form and

         (23) the obligation, if any, of the Company to permit the conversion
    of the Securities of such series into the Company's Common Stock or

    inconsistent with the provisions of this Indenture).

         All Securities of any one series and the coupons appertaining to any 
Bearer Securities of such series shall be substantially identical except, in 
the case of Registered Securities, as to denomination and except as may 
otherwise be provided in or pursuant to such Board Resolution (subject to 
Section 3.3) and set forth in such Officers' Certificate or in any such 
indenture supplemental hereto.  All Securities of any one series need not be 
issued at the same time and, unless otherwise provided, a series may be 
reopened, without the consent of the Holders, for issuances of additional 
Securities of such series.

         If any of the terms of the Securities of any series are established 
by action taken pursuant to one or more Board Resolutions, a copy of an 
appropriate record of such action(s) shall be certified by the Secretary or 
an Assistant Secretary of the Company and delivered to the Trustee at or 
prior to the delivery of the Officers' Certificate setting forth the terms of 
the Securities of such series.

    Section   3.2 Denominations.  The Securities of each series shall be 
issuable in such denominations as shall be specified as contemplated by 
Section 3.1.  With respect to Securities of any series denominated in 
Dollars, in the absence of any such provisions with respect to the Securities 
of any series, the Registered Securities of such series, other than 
Registered Securities issued in global form (which may be of any 
denomination), shall be issuable in denominations of $1,000 and any integral 
multiple thereof and the Bearer Securities of such series, other than Bearer 
Securities 


                                                                            23

issued in global form (which may be of any denomination), shall be issuable 
in a denomination of $5,000.

    Section   3.3 Execution, Authentication, Delivery and Dating.  The 
Securities and any coupons appertaining thereto shall be executed on behalf 
of the Company by a trustee and an executive officer of the Company and 
attested by its Secretary or one of its Assistant Secretaries.  The signature 
of any of these individuals on the Securities and coupons may be manual or 
facsimile signatures of the present or any future such authorized officer and 
trustee and may be imprinted or otherwise reproduced on the Securities.

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

         At any time and from time to time after the execution and delivery 
of this Indenture, the Company may deliver Securities of any series, together 
with any coupon appertaining thereto, executed by the Company to the Trustee 
for authentication, together with a Company Order for the authentication and 
delivery of such Securities, and the Trustee in accordance with the Company 
Order shall authenticate and deliver such Securities; provided, however, 
that, in connection with its original issuance, no Bearer Security shall be 
mailed or otherwise delivered to any location in the United States; and 
provided further that, unless otherwise specified with respect to any series 
of Securities pursuant to Section 3.1, a Bearer Security may be delivered in 
connection with its original issuance only if the Person entitled to receive 
such Bearer Security shall have furnished a certificate to Euroclear or 
CEDEL, as the case may be, in the form set forth in Exhibit A-1 to this 
Indenture or such other certificate as may be specified with respect to any 
series of Securities pursuant to Section 3.1, dated no earlier than 15 days 
prior to the earlier of the date on which such Bearer Security is delivered 
and the date on which any temporary Security first becomes exchangeable for 
such Bearer Security in accordance with the terms of such temporary Security 
and this Indenture.  If any Security shall be represented by a permanent 
global Bearer Security, then, for purposes of this Section and Section 3.4, 
the notation of a beneficial owner's interest therein upon original issuance 
of such Security or upon exchange of a portion of a temporary global Security 
shall be deemed to be delivery in connection with its original issuance of 
such beneficial owner's interest in such permanent global Security.  Except 
as permitted by Section 3.6, the Trustee shall not authenticate and deliver 
any Bearer Security unless all appurtenant coupons for interest then matured 
have been detached and canceled.

         If all the Securities of any series are not to be issued at one time 
and if the Board Resolution or supplemental indenture establishing such 
series shall so 


                                                                            24

permit, such Company Order may set forth procedures acceptable to the Trustee 
for the issuance of such Securities and determining the terms of particular 
Securities of such series, such as interest rate or formula, maturity date, 
date of issuance and date from which interest shall accrue.  In 
authenticating such Securities, and accepting the additional responsibilities 
under this Indenture in relation to such Securities, the Trustee shall be 
entitled to receive, and (subject to TIA Section 315(a) through 315(d)) shall 
be fully protected in relying upon,

         (i)  an Opinion of Counsel stating that 

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

              (b)  the terms of such Securities and any coupons have been
    established in conformity with the provisions of this Indenture; and

              (c)  such Securities, together with any coupons appertaining
    thereto, when completed by appropriate insertions and executed and
    delivered by the Company to the Trustee for authentication in accordance
    with this Indenture, authenticated and delivered by the Trustee in
    accordance with this Indenture and issued by the Company in the manner and
    subject to any conditions specified in such Opinion of Counsel, will
    constitute legal, valid and binding obligations of the Company, enforceable
    in accordance with their terms, subject to applicable bankruptcy,
    insolvency, reorganization and other similar laws of general applicability
    relating to or affecting the enforcement of creditors' rights generally and
    to general equitable principles; and

              (ii) an Officers' Certificate stating that all conditions
precedent provided for in this Indenture relating to the issuance of the
Securities have been complied with and that, to the best of the knowledge of the
signers of such certificate, no Event of Default with respect to any of the
Securities shall have occurred and be continuing. 

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

         Notwithstanding the provisions of Section 3.1 and of the preceding 
paragraph, if all the Securities of any series are not to be issued at one 
time, it shall not be necessary to deliver an Officers' Certificate otherwise 
required pursuant to Section 3.1 or a Company Order, or an Opinion of Counsel 
or an Officers' Certificate otherwise required pursuant to the preceding 
paragraph at the time of issuance of each Security of such series, but such 
order, opinion and certificates, with appropriate 


                                                                            25

modifications to cover such future issuances, shall be delivered at or before 
the time of issuance of the first Security of such series.

         Each Registered Security shall be dated the date of its 
authentication and each Bearer Security shall be dated as of the date 
specified as contemplated by Section 3.1.

         No Security or coupon shall be entitled to any benefit under this 
Indenture or be valid or obligatory for any purpose unless there appears on 
such Security or Security to which such coupon appertains a certificate of 
authentication substantially in the form provided for herein duly executed by 
the Trustee by manual signature of an authorized signatory, and such 
certificate upon any Security shall be conclusive evidence, and the only 
evidence, that such Security has been duly authenticated and delivered 
hereunder and is entitled to the benefits of this Indenture.  Notwithstanding 
the foregoing, if any Security shall have been authenticated and delivered 
hereunder but never issued and sold by the Company, and the Company shall 
deliver such Security to the Trustee for cancellation as provided in Section 
3.9 together with a written statement (which need not comply with Section 1.2 
and need not be accompanied by an Opinion of Counsel) stating that such 
Security has never been issued and sold by the Company, for all purposes of 
this Indenture such Security shall be deemed never to have been authenticated 
and delivered hereunder and shall never be entitled to the benefits of this 
Indenture.

    Section 3.4 Temporary Securities.  (a) Pending the preparation of 
definitive Securities of any series, the Company may execute, and upon 
Company Order the Trustee shall authenticate and deliver, temporary 
Securities which are printed, lithographed, typewritten, mimeographed or 
otherwise produced, in any authorized denomination, substantially of the 
tenor of the definitive Securities in lieu of which they are issued, in 
registered form, or, if authorized, in bearer form with one or more coupons 
or without coupons, and with such appropriate insertions, omissions, 
substitutions and other variations as the officers executing such Securities 
may determine, as conclusively evidenced by their execution of such 
Securities.  In the case of Securities of any series, 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 Section 3.4(b) or as otherwise provided 
in or pursuant to a Board Resolution) if temporary Securities of any series 
are issued, the Company will cause definitive Securities of that series to be 
prepared without unreasonable delay.  After the preparation of definitive 
Securities of such series, the temporary Securities of such series shall be 
exchangeable for definitive Securities of such series upon surrender of the 
temporary Securities of such series at the office or agency of the Company in 
a Place of Payment for that series, without charge to the Holder.  Upon 
surrender for cancellation of any one or more temporary Securities of any 
series (accompanied by any non-matured coupons appertaining thereto) the 
Company shall execute and the Trustee shall authenticate and deliver in 
exchange therefor a like principal amount of definitive Securities of the 
same series of authorized denominations; provided, however, that no 
definitive Bearer Security shall be delivered in exchange 


                                                                            26

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 Section 3.3. 
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.

         (b)  Unless otherwise provided in or pursuant to a Board Resolution, 
this Section 3.4(b) shall govern the exchange of temporary Securities issued 
in global form other than through the facilities of The Depository Trust 
Company. If any such temporary Security is issued in global form, then such 
temporary global Security shall, unless otherwise provided therein, be 
delivered to the London office of a depositary or common depositary (the 
"Common Depositary"), for the benefit of Euroclear and CEDEL, for credit to 
the respective accounts of the beneficial owners of such Securities (or to 
such other accounts as they may direct).

         Without unnecessary delay but in any event not later than the date 
specified in, or determined pursuant to the terms of, any such temporary 
global Security (the "Exchange Date"), the Company shall deliver to the 
Trustee definitive Securities, in aggregate principal amount equal to the 
principal amount of such temporary global Security, executed by the Company.  
On or after the Exchange Date, such temporary global Security shall be 
surrendered by the Common Depositary to the Trustee, as the Company's agent 
for such purpose, to be exchanged, in whole or from time to time in part, for 
definitive Securities without charge, and the Trustee shall authenticate and 
deliver, in exchange for each portion of such temporary global Security, an 
equal aggregate principal amount of definitive Securities of the same series 
of authorized denominations and of like tenor as the portion of such 
temporary global Security to be exchanged.  The definitive Securities to be 
delivered in exchange for any such temporary global Security shall be in 
bearer form, registered form, permanent global bearer form or permanent 
global registered form, or any combination thereof, as specified as 
contemplated by Section 3.1, and, if any combination thereof is so specified, 
as requested by the beneficial owner thereof; provided, however, that, unless 
otherwise specified in such temporary global Security, upon such presentation 
by the Common Depositary, such temporary global Security is accompanied by a 
certificate dated the Exchange Date or a subsequent date and signed by 
Euroclear as to the portion of such temporary global Security held for its 
account then to be exchanged and a certificate dated the Exchange Date or a 
subsequent date and signed by CEDEL as to the portion of such temporary 
global Security held for its account then to be exchanged, each in the form 
set forth in Exhibit A-2 to this Indenture or in such other form as may be 
established pursuant to Section 3.1; and provided further that definitive 
Bearer Securities shall be delivered in exchange for a portion of a temporary 
global Security only in compliance with the requirements of Section 3.3.


                                                                            27

         Unless otherwise specified in such temporary global Security, the 
interest of a beneficial owner of Securities of a series in a temporary 
global Security shall be exchanged for definitive Securities of the same 
series and of like tenor following the Exchange Date when the account holder 
instructs Euroclear or CEDEL, as the case may be, to request such exchange on 
his behalf and delivers to Euroclear or CEDEL, as the case may be, a 
certificate in the form set forth in Exhibit A-1 to this Indenture (or in 
such other form as may be established pursuant to Section 3.1), dated no 
earlier than 15 days prior to the Exchange Date, copies of which certificate 
shall be available from the offices of Euroclear and CEDEL, the Trustee, any 
Authenticating Agent appointed for such series of Securities and each Paying 
Agent. Unless otherwise specified in such temporary global Security, any such 
exchange shall be made free of charge to the beneficial owners of such 
temporary global Security, except that a Person receiving definitive 
Securities must bear the cost of insurance, postage, transportation and the 
like unless such Person takes delivery of such definitive Securities in 
person at the offices of Euroclear or CEDEL.  Definitive Securities in bearer 
form to be delivered in exchange for any portion of a temporary global 
Security shall be delivered only outside the United States.

         Until exchanged in full as hereinabove provided, the temporary 
Securities of any series shall in all respects be entitled to the same 
benefits under this Indenture as definitive Securities of the same series and 
of like tenor authenticated and delivered hereunder, except that, unless 
otherwise specified as contemplated by Section 3.1, interest payable on a 
temporary global Security on an Interest Payment Date for Securities of such 
series occurring prior to the applicable Exchange Date shall be payable to 
Euroclear and CEDEL on such Interest Payment Date upon delivery by Euroclear 
and CEDEL to the Trustee of a certificate or certificates in the form set 
forth in Exhibit A-2 to this Indenture (or in such other forms as may be 
established pursuant to Section 3.1), for credit without further interest on 
or after such Interest Payment Date to the respective accounts of Persons who 
are the beneficial owners of such temporary global Security on such Interest 
Payment Date and who have each delivered to Euroclear or CEDEL, as the case 
may be, a certificate dated no earlier than 15 days prior to the Interest 
Payment Date occurring prior to such Exchange Date in the form set forth as 
Exhibit A-1 to this Indenture (or in such other forms as may be established 
pursuant to Section 3.1).  Notwithstanding anything to the contrary herein 
contained, the certifications made pursuant to this paragraph shall satisfy 
the certification requirements of the preceding two paragraphs of this 
Section 3.4(b) and of the third paragraph of Section 3.3 of this Indenture 
and the interests of the Persons who are the beneficial owners of the 
temporary global Security with respect to which such certification was made 
will be exchanged for definitive Securities of the same series and of like 
tenor on the Exchange Date or the date of certification if such date occurs 
after the Exchange Date, without further act or deed by such beneficial 
owners.  Except as otherwise provided in this paragraph, no payments of 
principal or interest owing with respect to a beneficial interest in a 
temporary global Security will be made unless and until such interest in such 
temporary global Security shall have been exchanged for an interest in a 
definitive 


                                                                            28

Security.  Any interest so received by Euroclear and CEDEL and not paid as 
herein provided shall be returned to the Trustee prior to the expiration of 
two years after such Interest Payment Date in order to be repaid to the 
Company.

    Section   3.5 Registration, Registration of Transfer and Exchange.  The 
Company shall cause to be kept at the Corporate Trust Office of the Trustee 
or in any office or agency of the Company in a Place of Payment a register 
for each series of Securities (the registers maintained in such office or in 
any such office or agency of the Company in a Place of Payment being herein 
sometimes referred to collectively as the "Security Register") in which, 
subject to such reasonable regulations as it may prescribe, the Company shall 
provide for the registration of Registered Securities and of transfers of 
Registered Securities. The Security Register shall be in written form or any 
other form capable of being converted into written form within a reasonable 
time.  The Trustee, at its Corporate Trust Office, is hereby appointed 
"Security Registrar" for the purpose of registering Registered Securities and 
transfers of Registered Securities on such Security Register as herein 
provided.  In the event that the Trustee shall cease to be Security 
Registrar, it shall have the right to examine the Security Register at all 
reasonable times.

         Subject to the provisions of this Section 3.5, upon surrender for 
registration of transfer of any Registered Security of any series at any 
office or agency of the Company in a Place of Payment for that 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, of any authorized denominations and of a like 
aggregate principal amount, bearing a number not contemporaneously 
outstanding, and containing identical terms and provisions.

         Subject to the provisions of this Section 3.5, at the option of the 
Holder, Registered Securities of any series may be exchanged for other 
Registered Securities of the same series, of any authorized denomination or 
denominations and of a like aggregate principal amount, containing identical 
terms and provisions, upon surrender of the Registered Securities to be 
exchanged at any such office or agency.  Whenever any such 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.  Unless otherwise 
specified with respect to any series of Securities as contemplated by Section 
3.1, Bearer Securities may not be issued in exchange for Registered 
Securities.
 
         If (but only if) permitted by the applicable Board Resolution and 
(subject to Section 3.3) set forth in the applicable Officers' Certificate, 
or in any indenture supplemental hereto, delivered as contemplated by Section 
3.1, at the option of the Holder, Bearer Securities of any series may be 
exchanged for Registered Securities of the same series of any authorized 
denominations and of a like aggregate 


                                                                            29

principal amount and tenor, upon surrender of the Bearer Securities to be 
exchanged at any such office or agency, 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, any such permitted exchange may be effected if 
the Bearer Securities are accompanied by payment in funds acceptable to the 
Company 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 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 
10.2, interest represented by coupons shall be payable only upon presentation 
and surrender of those coupons at an office or agency located outside the 
United States. Notwithstanding the foregoing, in case a Bearer Security of 
any series is surrendered at any such office or agency in a permitted 
exchange for a Registered Security of the same 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 proposed date for payment 
of Defaulted Interest, such Bearer Security shall be surrendered without the 
coupon relating to such Interest Payment Date or proposed date for payment, 
as the case may be, and interest or Defaulted Interest, as the case may be, 
will 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 will be payable only to the Holder of 
such coupon when due in accordance with the provisions of this Indenture.  
Whenever any Securities are so surrendered for exchange, the Company shall 
execute, and the Trustee shall authenticate and deliver, the Securities which 
the Holder making the exchange is entitled to receive.

         Notwithstanding the foregoing, except as otherwise specified as 
contemplated by Section 3.1, any permanent global Security shall be 
exchangeable only as provided in this paragraph.  If the depositary for any 
permanent global Security is The Depository Trust Company ("DTC"), then, 
unless the terms of such global Security expressly permit such global 
Security to be exchanged in whole or in part for definitive Securities, a 
global Security may be transferred, in whole but not in part, only to a 
nominee of DTC, or by a nominee of DTC to DTC, or to a successor to DTC for 
such global Security selected or approved by the Company or to a nominee of 
such successor to DTC.  If at any time DTC notifies the Company that it is 
unwilling or unable to continue as depositary for the applicable global 
Security or Securities or if at any time DTC ceases to be a clearing agency 
registered under the Securities Exchange Act of 1934 if so required by 
applicable law or regulation, the Company shall appoint a successor 
depositary with respect to such global Security or Securities.  If (x) a 
successor depositary for such global Security or Securities is not 


                                                                            30

appointed by the Company within 90 days after the Company receives such 
notice or becomes aware of such unwillingness, inability or ineligibility, 
(y) an Event of Default has occurred and is continuing and the beneficial 
owners representing a majority in principal amount of the applicable series 
of Securities represented by such global Security or Securities advise DTC to 
cease acting as depositary for such global Security or Securities or (z) the 
Company, in its sole discretion, determines at any time that all Outstanding 
Securities (but not less than all) of any series issued or issuable in the 
form of one or more global Securities shall no longer be represented by such 
global Security or Securities, then the Company shall execute, and the 
Trustee shall authenticate and deliver definitive Securities of like series, 
rank, tenor and terms in definitive form in an aggregate principal amount 
equal to the principal amount of such global Security or Securities.  If any 
beneficial owner of an interest in a permanent global Security is otherwise 
entitled to exchange such interest for Securities of such series and of like 
tenor and principal amount of another authorized form and denomination, as 
specified as contemplated by Section 3.1 and provided that any applicable 
notice provided in the permanent global Security shall have been given, then 
without unnecessary delay but in any event not later than the earliest date 
on which such interest may be so exchanged, the Company shall execute, and 
the Trustee shall authenticate and deliver definitive Securities in aggregate 
principal amount equal to the principal amount of such beneficial owner's 
interest in such permanent global Security.  On or after the earliest date on 
which such interests may be so exchanged, such permanent global Security 
shall be surrendered for exchange by DTC or such other depositary as shall be 
specified in the Company Order with respect thereto to the Trustee, as the 
Company's agent for such purpose; provided, however, that no such exchanges 
may occur during a period beginning at the opening of business 15 days before 
any selection of Securities to be redeemed and ending on the relevant 
Redemption Date if the Security for which exchange is requested may be among 
those selected for redemption; and provided further that no Bearer Security 
delivered in exchange for a portion of a permanent global Security shall be 
mailed or otherwise delivered to any location in the United States.  If a 
Registered Security is issued in exchange for any portion of a permanent 
global Security after the close of business at the office or agency where 
such exchange occurs 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 the opening of business at such office or 
agency on the related proposed date for payment of Defaulted Interest, 
interest or Defaulted Interest, as the case may be, will 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 will 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 permanent global 
Security is payable in accordance with the provisions of this Indenture.

         All Securities issued upon any registration of transfer or exchange 
of Securities shall be the valid obligations of the Company, evidencing the 
same debt, 


                                                                            31

and entitled 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) be duly endorsed, or be accompanied by a 
written instrument of transfer in form satisfactory to the Company and the 
Security Registrar, duly executed by the Holder thereof or his attorney duly 
authorized in writing.

         No service charge shall be made for any registration of transfer or 
exchange of Securities, but the Company may require payment of a sum 
sufficient to cover any tax or other governmental charge that may be imposed 
in connection with any registration of transfer or exchange of Securities, 
other than exchanges pursuant to Section 3.4, 9.6, 11.7 or 13.5 not involving 
any transfer.

         The Company or the Trustee, as applicable, shall not be required (i) 
to issue, register the transfer of or exchange any Security if such Security 
may be among those selected for redemption during a period beginning at the 
opening of business 15 days before selection of the Securities to be redeemed 
under Section 11.3 and ending at the close of business on (A) if such 
Securities are issuable only as Registered Securities, the day of the mailing 
of the relevant notice of redemption and (B) if such Securities are issuable 
as Bearer Securities, the day of the first publication of the relevant notice 
of redemption or, if such Securities are also issuable as Registered 
Securities and there is no publication, the mailing of the relevant notice of 
redemption, 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 Registered 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 that such a Bearer Security may be exchanged for a 
Registered Security of that series and like tenor, provided that such 
Registered Security shall be simultaneously surrendered for redemption, or 
(iv) to issue, register the transfer of or exchange any Security which has 
been surrendered for repayment at the option of the Holder, except the 
portion, if any, of such Security not to be so repaid.

    Section 3.6 Mutilated, Destroyed, Lost and Stolen Securities.  If any 
mutilated Security or a Security with a mutilated coupon appertaining to it 
is surrendered to the Trustee or the Company, together with, in proper cases, 
such security or indemnity as may be required by the Company or the Trustee 
to save each of them or any agent of either of them harmless, the Company 
shall execute and the Trustee shall authenticate and deliver in exchange 
therefor a new Security of the same series and principal amount, containing 
identical terms and provisions and bearing a number not contemporaneously 
outstanding, with coupons corresponding to the coupons, if any, appertaining 
to the surrendered Security.

                                                                             32

         If there shall be delivered to the Company and to the Trustee
(i) evidence to their satisfaction of the destruction, loss or theft of any
Security 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 its
request the Trustee shall authenticate and deliver, in lieu of any such
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 and principal
amount, containing identical terms and provisions 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 provisions of the previous two paragraphs in case
any such 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, 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, pay such Security or
coupon; provided, however, that payment of principal of (and premium, if any),
any interest on and any Additional Amounts with respect to, Bearer Securities
shall, except as otherwise provided in Section 10.2, be payable only at an
office or agency located outside the United States and, unless otherwise
specified as contemplated by Section 3.1, any interest on Bearer Securities
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 of any series with its coupons, if any, 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 an original additional contractual obligation of
the Company, whether or not the destroyed, lost or stolen Security and its
coupons, if any, 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 that
series and their coupons, if any, duly issued hereunder. 

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


                                                                             33

           Section 3.7 Payment of Interest; Interest Rights Preserved.  
Except as otherwise specified with respect to a series of Securities in 
accordance with the provisions of Section 3.1, interest on any Registered 
Security that is payable, and is punctually paid or duly provided for, on any 
Interest Payment Date shall be paid to the Person in whose name that Security 
(or one or more Predecessor Securities) is registered at the close of 
business on the Regular Record Date for such interest at the office or agency 
of the Company maintained for such purpose pursuant to Section 10.2; 
provided, however, that each installment of interest on any Registered 
Security may at the Company's option be paid by (i) mailing a check for such 
interest, payable to or upon the written order of the Person entitled thereto 
pursuant to Section 3.8, to the address of such Person as it appears on the 
Security Register or (ii) transfer to an account maintained by the payee 
located inside the United States. 

         Unless otherwise provided as contemplated by Section 3.1 with respect
to the Securities of any series, payment of interest may be made, in the case of
a Bearer Security, by transfer to an account maintained by the payee with a bank
located outside the United States. 

         Unless otherwise provided as contemplated by Section 3.1, every
permanent global Security will provide that interest, if any, payable on any
Interest Payment Date will be paid to DTC, Euroclear and/or CEDEL, as the case
may be, with respect to that portion of such permanent global Security held for
its account by Cede & Co. or the Common Depositary, as the case may be, for the
purpose of permitting such party to credit the interest received by it in
respect of such permanent global Security to the accounts of the beneficial
owners thereof. 

         In case a Bearer Security of any series is surrendered in exchange for
a Registered Security of such series after the close of business (at an office
or agency in a Place of Payment for such series) on any Regular Record Date and
before the opening of business (at such office or agency) on the next succeeding
Interest Payment Date, such Bearer Security shall be surrendered without the
coupon relating to such Interest Payment Date and interest will not be payable
on such Interest Payment Date in respect of the Registered Security issued in
exchange for such Bearer Security, but will be payable only to the Holder of
such coupon when due in accordance with the provisions of this Indenture.

         Except as otherwise specified with respect to a series of Securities
in accordance with the provisions of Section 3.1, any interest on any Registered
Security of any series that is payable, but is not punctually paid or duly
provided for, on any Interest Payment Date (herein called "Defaulted Interest")
shall forthwith cease to be payable to the registered 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:


                                                                             34

         (1)  The Company may elect to make payment of any Defaulted Interest
    to the Persons in whose names the Registered Securities of such series (or
    their respective Predecessor Securities) are registered at the close of
    business on a Special Record Date for the payment of such Defaulted
    Interest, which shall be fixed in the following manner.  The Company shall
    notify the Trustee in writing of the amount of Defaulted Interest proposed
    to be paid on each Registered Security of such series and the date of the
    proposed payment (which shall not be less than 20 days after such notice is
    received by the Trustee), and at the same time the Company shall deposit
    with the Trustee an amount of money in the currency or currencies, currency
    unit or units or composite currency or currencies in which the Securities
    of such series are payable (except as otherwise specified pursuant to
    Section 3.1 for the Securities of such series) 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 deposited to be held
    in trust for the benefit of the Persons entitled to such Defaulted Interest
    as in this clause provided.  Thereupon the Trustee shall fix a Special
    Record Date for the payment of such Defaulted Interest which shall be not
    more that 15 days and not less than 10 days prior to the date of the
    proposed payment and not less than 10 days after the receipt by the Trustee
    of the notice of the proposed payment.  The Trustee shall promptly notify
    the Company of such Special Record Date and, in the name and at the expense
    of the Company, shall cause notice of the proposed payment of such
    Defaulted Interest and the Special Record Date therefor to be mailed,
    first-class postage prepaid, to each Holder of Registered Securities of
    such series 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 in each
    place of payment, but such publications shall not be a condition precedent
    to the establishment of such Special Record Date.  Notice of the proposed
    payment of such Defaulted Interest and the Special Record Date therefor
    having been mailed as aforesaid, such Defaulted Interest shall be paid to
    the Persons in whose names the Registered Securities of such series (or
    their respective Predecessor Securities) are registered at the close of
    business on such Special Record Date and shall no longer be payable
    pursuant to the following clause (2).  In case a Bearer Security of any
    series is surrendered at the office or agency in a Place of Payment for
    such series in exchange for a Registered Security of such series 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 proposed date of payment
    and Defaulted Interest will not be payable on such proposed date of payment
    in respect of the Registered Security issued in 


                                                                            35

    exchange for such Bearer Security, but will 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 on the
    Registered Securities of any series in any other lawful manner not
    inconsistent with the requirements of any securities exchange on which such
    Securities may be listed, and upon such notice as may be required by such
    exchange, if, after notice given by the Company to the Trustee of the
    proposed payment pursuant to this clause, such manner of payment shall be
    deemed practicable by the Trustee.

         Subject to the foregoing provisions of this Section and Section 3.5,
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 3.8 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 as the owner of such Security for 
the purpose of receiving payment or principal of (and premium, if any), and 
(subject to Sections 3.5 and 3.7) interest on, such Registered Security and 
for all other purposes whatsoever, whether or not such Registered Security be 
overdue, and neither the Company, the Trustee nor any agent of the Company or 
the Trustee shall be affected by notice to the contrary. 

         Title to any Bearer Security and any coupons appertaining thereto
shall pass by delivery.  The Company, the Trustee and any agent of the Company
or the Trustee may treat the Holder of any Bearer Security and the Holder of any
coupon as the absolute owner of such Security or coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Security or coupon be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary. 

         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 Security in global form or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests. 

         Notwithstanding the foregoing, with respect to any global Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by any depositary, as a Holder, with respect to
such global Security or impair, as between such depositary and owners of
beneficial interests in 


                                                                            36

such global Security, the operation of customary practices governing the 
exercise of the rights of such depositary (or its nominee) as Holder of such 
global Security. 

         Section 3.9 Cancellation.  All Securities and coupons surrendered 
for payment, redemption, repayment at the option of the Holder, registration 
of transfer or exchange or for credit against any sinking fund payment shall, 
if surrendered to any Person other than the Trustee, be delivered to the 
Trustee, and any such Securities and coupons and Securities and coupons 
surrendered directly to the Trustee for any such purpose shall be promptly 
canceled by it.  The Company may at any time deliver to the Trustee for 
cancellation any Securities previously authenticated and delivered hereunder 
which the Company may have acquired in any manner whatsoever, and may deliver 
to the Trustee (or to any other Person for delivery to the Trustee) for 
cancellation any Securities previously authenticated hereunder which the 
Company has not issued and sold, and all Securities so delivered shall be 
promptly canceled by the Trustee.  If the Company shall so acquire any of the 
Securities however, such acquisition shall not operate as a redemption or 
satisfaction of the indebtedness represented by such Securities unless and 
until the same are surrendered to the Trustee for cancellation.  No 
Securities shall be authenticated in lieu of or in exchange for any 
Securities canceled as provided in this Section, except as expressly 
permitted by this Indenture.  Canceled Securities and coupons held by the 
Trustee shall be destroyed by the Trustee and the Trustee shall deliver a 
certificate of such destruction to the Company, unless by a Company Order the 
Company directs their return to it.

         Section 3.10 Computation of Interest.  Except as otherwise specified 
as contemplated by Section 3.1 with respect to Securities of any series, 
interest on the Securities of each series shall be computed on the basis of a 
360-day year consisting of twelve 30-day months.

         Section 4.1 Satisfaction and Discharge of Indenture.  This Indenture 
shall upon Company Request cease to be of further effect with respect to any 
series of Securities specified in such Company Request (except as to any 
surviving rights of registration of transfer or exchange of Securities of 
such series herein expressly provided for and any right to receive Additional 
Amounts, and the Trustee, upon receipt of a Company Order, and at the expense 
of the Company, shall execute proper instruments acknowledging satisfaction 
and discharge of this Indenture as to such series when 


                                                                            37

         delivered and all coupons, if any, appertaining thereto (other than
         (i) coupons appertaining to Bearer Securities surrendered for exchange

         surrender is not required or has been waived as provided in
         Section 3.5, (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 3.6, (iii) coupons appertaining to Securities

         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 10.3) 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

              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
         irrevocably deposited or caused to be deposited with the Trustee as
         trust funds in trust for the purpose (A) an amount of money in the
         currency or currencies, currency unit or units or composite currency
         or currencies in which the Securities of such series are payable, (B)
         Government Obligations that through the scheduled payment of principal
         and interest in respect thereof in accordance with their terms will
         provide, not later than on day before the due date of any payment,
         money in an amount, or (C) a combination thereof, sufficient to pay
         and discharge the entire indebtedness on such Securities and such
         coupons not theretofore delivered to the Trustee for cancellation, for
         principal (and premium, if any) and interest, and any Additional
         Amounts with respect thereto, to the date of such deposit (in the case
         of Securities which have become due and payable) or to the Stated
         Maturity or Redemption Date, as the case may be; 


                                                                            38

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

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

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee and any predecessor Trustee under
Section 6.6, the obligations of the Company to any Authenticating Agent under
Section 6.11 and, if money shall have been deposited with and held by the
Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations
of the Trustee under Section 4.2 and the last paragraph of Section 10.3 shall
survive.

         Section 4.2 Application of Trust Funds.  Subject to the provisions 
of the last paragraph of Section 10.3, all money deposited with the Trustee 
pursuant to Section 4.1 shall be held in trust and applied by 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 (and premium, if 
any), and any interest and Additional Amounts for whose payment such money 
has been deposited with or received by the Trustee, but such money need not 
be segregated from other funds except to the extent required by law.

         Section 5.1 Events of Default.  "Event of Default," wherever used 
herein with respect to any particular series of Securities, means any one of 
the following events (whatever the reason for such Event of Default and 
whether or not it shall be voluntary or involuntary or be effected by 
operation of law or pursuant to any judgment, decree or order of any court or 
any order, rule or regulation of any administrative or governmental body): 

         (1)  default in the payment of any interest upon or any Additional
    Amounts payable in respect of any Security of that series or of any coupon
    appertaining thereto, when such interest, Additional Amounts or coupon
    becomes due and payable, and continuance of such default for a period of 30
    days; or


                                                                            39

         (2)  default in the payment of the principal of (or premium, if any,
    on) any Security of that series when it becomes due and payable at its
    Maturity; or

         (3)  default in the deposit of any sinking fund payment, when and as
    due by the terms of any Security of that series; or

         (4)  default in the performance, or breach, of any covenant or
    warranty of the Company in this Indenture with respect to any Security of
    that series (other than a covenant or warranty a default in whose
    performance or whose breach is elsewhere in this Section specifically dealt
    with), and continuance of such default or breach for a period of 90 days
    after there has been given, by registered or certified mail, to the Company
    by the trustee or to the Company and the Trustee by the Holders of at least
    25% in principal amount of the Outstanding Securities of that series a
    written notice specifying such default or breach and requiring it to be
    remedied and stating that such notice is a "Notice of Default" hereunder;
    or

         (5)  the Company or any Significant Subsidiary pursuant to or within
    the meaning of any Bankruptcy Law: 

              (A)  commences a voluntary case,

              (B)  consents to the entry of an order for relief against it in
         an involuntary case,

              (C)  consents to the appointment of a Custodian of it or for all
         or substantially all of its property, or

              (D)  makes a general assignment for the benefit of its creditors;
         or

         (6)  a court of competent jurisdiction enters an order or decree under
    any Bankruptcy Law that:

              (A)  is for relief against the Company or any Significant
         Subsidiary in an involuntary case,

              (B)  appoints a Custodian of the Company or any Significant
         Subsidiary or for all or substantially all of either of its property,
         or

              (C)  orders the liquidation of the Company or any Significant
         Subsidiary, and the order or decree remains unstayed and in effect
         for 90 days; or

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

or any similar Federal or State law for the relief of debtors and the term
"Custodian" means any receiver, trustee, assignee, liquidator or other similar
official under any Bankruptcy Law. 

         Section 5.2 Acceleration of Maturity; Rescission and Annulment.  If 
an Event of Default with respect to Securities of any series at the time 
Outstanding occurs and is continuing, then and in every such case the Trustee 
or the Holders of not less than 25% in principal amount of the Outstanding 
Securities of that series may declare the principal (or, if any Securities 
are Original Issue Discount Securities or Indexed Securities, such portion of 
the principal as may be specified in the terms thereof) of all the Securities 
of that series to be due and payable immediately, by a notice in writing to 
the Company (and to the Trustee if given by the Holders), and upon any such 
declaration such principal or specified portion thereof shall become 
immediately due and payable. 

         At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that 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
    sufficient to pay in the currency, currency unit or composite currency in
    which the Securities of such series  are payable (except as otherwise
    specified pursuant to Section 3.1 for the Securities of such series):

              (A)  all overdue installments of interest on and any Additional
         Amounts payable in respect of all Outstanding Securities of that
         series and any related coupons,

              (B)  the principal of (and premium, if any, on) any Outstanding
         Securities of that series which have become due otherwise than by such
         declaration of acceleration and interest thereon at the rate or rates
         borne by or provided for in such Securities,

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


                                                                            41

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

         (2)  all Events of Default with respect to Securities of that series,
    other than the nonpayment of the principal of (or premium, if any) or
    interest on Securities of that series which have become due solely by such
    declaration of acceleration, have been cured or waived as provided in
    Section 5.13.

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

         Section 5.3 Collection of Indebtedness and Suits for Enforcement by 
Trustee. The Company covenants that if:

              (1)  default is made in the payment of any installment of
         interest or Additional Amounts, if any, on any Security of any series
         and any related coupon when such interest or Additional Amount becomes
         due and payable and such default continues for a period of 30 days, or 

              (2)  default is made in the payment of the principal of (or
         premium, if any, on) any Security of any series at its Maturity, 

then the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities of such series and coupons, the whole
amount then due and payable on such Securities and coupons for principal (and
premium, if any) and interest and Additional Amount, with interest upon any
overdue principal (and premium, if any) and, to the extent that payment of such
interest shall be legally enforceable, upon any overdue installments of interest
or Additional Amounts, if any, at the rate or rates borne by or provided for in
such Securities, and, in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel. 

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


                                                                            42

rights and the rights of the Holders of Securities of such series and any 
related coupons by such appropriate judicial proceedings as the Trustee shall 
deem most effectual to protect and enforce any such rights, whether for the 
specific enforcement of any covenant or agreement in this Indenture or in aid 
of the exercise of any power granted herein, or to enforce any other proper 
remedy. 

         Section 5.4 Trustee May File Proofs of Claim.  In case of the 
pendency of any receivership, insolvency, liquidation, bankruptcy, 
reorganization, arrangement, adjustment, composition or other judicial 
proceeding relative to the Company or any other obligor upon the Securities 
or the property of the Company or of such other obligor or their creditors, 
the Trustee (irrespective of whether the principal of the Securities of any 
series shall then be due and payable as therein expressed or by declaration 
or otherwise and irrespective of whether the Trustee shall have made any 
demand on the Company for the payment of overdue principal, premium, if any, 
or interest) shall be entitled and empowered, by intervention in such 
proceeding or otherwise: 

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

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator (or
other similar official) in any such judicial proceeding is hereby authorized by
each Holder of Securities of such series and 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, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee and any predecessor Trustee, their agents and counsel, and any other
amounts due the Trustee or any predecessor Trustee under Section 6.6.

         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 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 coupon in any such proceeding.


                                                                            43

         Section 5.5 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 of judgment shall, after 
provision for the payment of the reasonable compensation, expenses, 
disbursements and advances of the Trustee, its agents and counsel, be for the 
ratable benefit of the Holders of the Securities and coupons in respect of 
which such judgment has been recovered. 

         Section 5.6 Application of Money Collected.  Any money collected by 
the Trustee pursuant to this Article shall be applied in the following order, 
at the date or dates fixed by the Trustee and, in case of the distribution of 
such money on account of principal (or premium, if any) or interest and any 
Additional Amounts, upon presentation of the Securities or coupons, or both, 
as the case may be, and the notation thereon of the payment if only partially 
paid and upon surrender thereof if fully paid:

         FIRST:  To the payment of all amounts due the Trustee and any
    predecessor Trustee under Section 6.6;

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

         THIRD:  To the payment of the remainder, if any, to the Company.

         Section 5.7 Limitation on Suits.  No Holder of any Security of any 
series or any related coupon 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 that
    series;

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


                                                                            44

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

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

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

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

         Section 5.8 Unconditional Right of Holders to Receive Principal, 
Premium, if any, Interest and Additional Amounts.  Notwithstanding any other 
provision in this Indenture, the Holder of any Security or coupon shall have 
the right which is absolute and unconditional to receive payment of the 
principal of (and premium, if any) and (subject to Sections 3.5 and 3.7) 
interest on, and any Additional Amounts in respect of, such Security or 
payment of such coupon on the respective due dates expressed in such Security 
or coupon (or, in the case of redemption, on the Redemption Date) and to 
institute suit for the enforcement of any such payment, and such rights shall 
not be impaired without the consent of such Holder. 

         Section 5.9 Restoration of Rights and Remedies.  If the Trustee or 
any Holder of a Security or 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 the Holders of Securities and coupons 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 the Holders shall continue as though no such proceeding had 
been instituted. 

         Section 5.10 Rights and Remedies Cumulative.  Except as otherwise 
provided with respect to the replacement or payment of mutilated, destroyed, 
lost or stolen Securities or coupons in the last paragraph of Section 3.6, no 
right or remedy herein conferred upon or reserved to the Trustee or to the 
Holders of Securities or coupons is intended to be exclusive of any other 
right or remedy, and every right and remedy shall, to the extent permitted by 
law, be cumulative and in addition to every other right and remedy given 
hereunder or now or hereafter existing at law or in 


                                                                            45

equity or otherwise.  The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy. 

         Section 5.11 Delay or Omission Not Waiver.  No delay or omission of 
the Trustee or of any Holder of any 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 the Holders may be exercised from time to time, and as often as 
may be deemed expedient, by the Trustee or by the Holders of Securities or 
coupons, as the case may be. 

         Section 5.12 Control by Holders of Securities.  The Holders of not 
less than a majority in principal amount of the Outstanding Securities of any 
series shall have the right to direct the time, method and place of 
conducting any proceeding for any remedy available to the Trustee or 
exercising any trust or power conferred on the Trustee with respect to the 
Securities of such series, provided that 

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

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

              (3)  the Trustee need not take any action which might involve it
         in personal liability or be unduly prejudicial to the Holders of
         Securities of such series not joining therein.

         Section 5.13 Waiver of Past Defaults.  The Holders of not less than 
a majority in principal amount of the Outstanding Securities of any series 
may on behalf of the Holders of all the Securities of such series and any 
related coupons waive any past default hereunder with respect to such series 
and its consequences, except a default 

              (1)  in the payment of the principal of (or premium, if any) or
         interest on or Additional Amounts payable in respect of any Security
         of such series or any related coupons, 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 


                                                                            46

this Indenture; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.

         Section 5.14 Waiver of Usury, Stay or Extension Laws.  The Company 
covenants (to the extent that it may lawfully do so) that it will not at any 
time insist upon, or plead, or in any manner whatsoever claim or take the 
benefit or advantage of, any usury, stay or extension law wherever enacted, 
now or at any time hereafter in force, which may affect the covenants or the 
performance of this Indenture; and the Company (to the extent that it may 
lawfully do so) hereby expressly waives all benefit or advantage of any such 
law, and covenants that it will not hinder, delay or impede the execution of 
any power herein granted to the Trustee, but will suffer and permit the 
execution of every such power as though no such law had been enacted. 

         Section 5.15 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 in 
such suit having due regard to the merits and good faith of the claims or 
defenses made by such party litigant; but the provisions of this Section 
shall not apply to any suit instituted by the Trustee, to any suit instituted 
by any Holder, or group of Holders, holding in the aggregate more than 10% in 
principal amount of the Outstanding Securities, or to any suit instituted by 
any Holder for the enforcement of the payment of the principal of (or 
premium, if any) or interest on any Security on or after the respective 
Stated Maturities expressed in such Security (or, in the case of redemption, 
on or after the Redemption Date). 

                                      ARTICLE 6

                                     THE TRUSTEE
                                           
         Section 6.1  Notice of Defaults.  Within 90 days after the 
occurrence of any default hereunder with respect to the Securities of any 
series, the Trustee shall transmit in the manner and to the extent provided 
in TIA Section 313(c), notice of such default hereunder known to the Trustee, 
unless such default shall have been cured or waived; provided, however, that, 
except in the case of a default in the payment of the principal of (or 
premium, if any) or interest on or any Additional Amounts with respect to any 
Security of such series, or in the payment of any sinking fund installment 
with respect to the Securities of such series, the Trustee shall be protected 
in withholding such notice if and so long as Responsible Officers of the 
Trustee in good faith determine that the withholding of such notice is in the 
interests 


                                                                            47

of the Holders of the Securities and coupons of such series; and provided 
further that in the case of any default or breach of the character specified 
in Section 5.1(4) with respect to the Securities and coupons of such series, 
no such notice to Holders shall be given until at least 90 days after the 
occurrence thereof.  For the purpose of this Section, the term "default" 
means any event which is, or after notice or lapse of time or both would 
become, an Event of Default with respect to the Securities of such series. 

         Section 6.2 Certain Rights of Trustee.  Subject to the provisions of 
TIA Section 315(a) through 315(d):

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

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

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

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

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

         (6)  the Trustee shall not be bound to make any investigation into the
    facts or matters stated in any resolution, certificate, statement,
    instrument, 


                                                                            48

    opinion, report, notice, request, direction, consent, order,
    bond, debenture, note, coupon or other paper or document, but the Trustee,
    in its discretion, may make such further inquiry or investigation into such
    facts or matters as it may see fit, and if the Trustee shall determine to
    make such further inquiry or investigation, it shall be entitled to examine
    the books, records and premises of the Company, personally or by agent or
    attorney following reasonable notice to the Company;

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

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

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

         Except during the continuance of an Event of Default, the Trustee
undertakes to perform only such duties as are specifically set forth in this
Indenture, and no implied covenants or obligations shall be read into this
Indenture against the Trustee.

         Section 6.3 Not Responsible for Recitals or Issuance of Securities.  
The recitals contained herein and in the Securities, except the Trustee's 
certificate of authentication, and in any coupons shall be taken as the 
statements of the Company, and neither the Trustee nor any Authenticating 
Agent assumes any responsibility for their correctness.  The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the 
Securities or coupons, except that the Trustee represents that it is duly 
authorized to execute and deliver this Indenture, authenticate the Securities 
and perform its obligations hereunder.  Neither the Trustee nor any 
Authenticating Agent shall be accountable for the use or application by the 
Company of Securities or the proceeds thereof. 

         Section 6.4 May Hold Securities.  The Trustee, any Paying Agent, 
Security Registrar, Authenticating Agent or any other agent of the Company, 
in its individual or any other capacity, may become the owner or pledgee of 
Securities and coupons and, subject to TIA Sections 310(b) and 311, may 
otherwise deal with the 


                                                                            49

Company with the same rights it would have if it were not Trustee, Paying
Agent, Security Registrar, Authenticating Agent or such other agent. 

         Section 6.5 Money Held in Trust.  Money held by the Trustee in trust 
hereunder need not be segregated from other funds except to the extent 
required by law. The Trustee shall be under no liability for interest on any 
money received by it hereunder except as otherwise agreed with the Company.

         Section 6.6 Compensation and Reimbursement.  The Company agrees:

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

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

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

         When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 5.1(5) or Section 5.1(6), the
expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law. 

         As security for the performance of the obligations of the Company
under this Section, the Trustee shall have a lien prior to the Securities upon
all property and funds held or collected by the Trustee as such, except funds
held in trust for the payment of principal of (or premium, if any) or interest
on particular Securities or any coupons. 

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


                                                                            50

         Section 6.7 Corporate Trustee Required; Eligibility; Conflicting 
Interests. There shall at all times be a Trustee hereunder which shall be 
eligible to act as Trustee under TIA Section 310(a)(1) and shall have a 
combined capital and surplus of at least $50,000,000.  If such corporation 
publishes reports of condition at least annually, pursuant to law or the 
requirements of Federal, State, Territorial or District of Columbia 
supervising or examining authority, then for the purposes of this Section, 
the combined capital and surplus of such corporation shall be deemed to be 
its combined capital and surplus as set forth in its most recent report of 
condition so published.  If at any time the Trustee shall cease to be 
eligible in accordance with the provisions of this Section, it shall resign 
immediately in the manner and with the effect hereinafter specified in this 
Article.  If the Trustee has or shall acquire a conflicting interest within 
the meaning of the TIA, the Trustee shall either eliminate such interest or 
resign to the extent and in the manner provided by and subject to the 
provisions of the TIA and this Indenture. 

         Section 6.8 Resignation and Removal; Appointment of Successor.

         (a)    No resignation or removal of the Trustee and no appointment 
of a successor Trustee pursuant to this Article shall become effective until 
the acceptance of appointment by the successor Trustee in accordance with the 
applicable requirements of Section 6.9.

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

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

         (d)    If at any time:

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

              (2)  the Trustee shall cease to be eligible under Section 6.7 and
    shall fail to resign after written request therefor by the Company or by
    any Holder of a Security who has been a bona fide Holder of a Security for
    at least six months, or


                                                                            51

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

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

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

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

         Section 6.9 Acceptance of Appointment by Successor.   In case of the 
appointment hereunder of a successor Trustee with respect to all Securities, 
every 


                                                                            52

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

         (b)    In case of the appointment hereunder of a successor Trustee 
with respect to the Securities of one or more (but not all) series, the 
Company, the retiring Trustee and each successor Trustee with respect to the 
Securities of one or more series shall execute and deliver an indenture 
supplemental hereto, pursuant to Article Nine hereof, wherein each successor 
Trustee shall accept such appointment and which (1) shall contain such 
provisions as shall be necessary or desirable to transfer and confirm to, and 
to vest in, each successor Trustee all the rights, powers, trusts and duties 
of the retiring Trustee with respect to the Securities of that or those 
series to which the appointment of such successor Trustee relates, (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 constitute such Trustees 
co-trustees of the same trust and that each such Trustee shall be trustee of 
a trust or trusts hereunder separate and apart from any trust or trusts 
hereunder administered by any other such Trustee; and upon the execution and 
delivery of such supplemental indenture the resignation or removal of the 
retiring Trustee shall become effective to the extent provided therein and 
each such successor Trustee, without any further act, deed or conveyance, 
shall become vested with all the rights, powers, trusts and duties of the 
retiring Trustee with respect to the Securities of that or those series to 
which the appointment of such successor Trustee relates; but, on request of 
the Company or any successor Trustee, such retiring Trustee shall duly 
assign, transfer and deliver to such successor Trustee all property and money 
held by such retiring Trustee hereunder with respect to the Securities of 
that or those series to which the appointment of such successor Trustee 
relates. 

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


                                                                            53

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

         Section 6.10 Merger, Conversion, Consolidation or Succession to 
Business.  Any corporation into which the Trustee may be merged or converted 
or with which it may be consolidated, or any corporation resulting from any 
merger, conversion or consolidation to which the Trustee shall be a party, or 
any corporation succeeding to all or substantially all of the corporate trust 
business of the Trustee, shall be the successor of the Trustee hereunder, 
provided such corporation shall be otherwise qualified and eligible under 
this Article, without the execution or filing of any paper or any further act 
on the part of any of the parties hereto.  In case any Securities or coupons 
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 or coupons so authenticated with the same effect as if such 
successor Trustee had itself authenticated such Securities or coupons.  In 
case any Securities or coupons shall not have been authenticated by such 
predecessor Trustee, any such successor Trustee may authenticate and deliver 
such Securities or coupons, in either its own name or that of its predecessor 
Trustee, with the full force and effect which this Indenture provides for the 
certificate of authentication of the Trustee. 

         Section 6.11. Appointment of Authenticating Agent.  At any time when 
any of the Securities remain Outstanding, the Trustee may appoint an 
Authenticating Agent or Agents with respect to one or more series of 
Securities which shall be authorized to act on behalf of the Trustee to 
authenticate Securities of such series issued upon exchange, registration of 
transfer or partial redemption or repayment thereof, 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.  Any such appointment shall be evidenced by an instrument in 
writing signed by a Responsible Officer of the Trustee, a copy of which 
instrument shall be promptly furnished to the Company. 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 shall at all 
times be a bank or trust company or corporation organized and doing business 
and in good standing under the laws of the United States of America or of any 
State or the District of Columbia, authorized under such laws to act as 
Authenticating Agent, having a combined capital and surplus of not less than 
$50,000,000 and subject to supervision or examination by Federal or State 
authorities.  If such Authenticating Agent publishes reports of condition at 
least annually, pursuant to law or the requirements of the aforesaid 
supervising or examining authority, then for the purposes of this Section, 
the combined capital and surplus of such Authenticating 


                                                                            54

Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published.  In case at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section. 

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

         An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Company.  The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment to all Holders of Securities of the series with
respect to which such Authenticating Agent will serve in the manner set forth in
Section 1.6.  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 herein.  No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section. 

         The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation including reimbursement of its reasonable expenses
for its services under this Section.

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

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


                                                                            55

                             By:                            ,
                                  as Authenticating Agent


                             By:                              ,

         Section 7.1 Disclosure of Names and Addresses of Holders.  Every 
Holder of Securities or coupons, by receiving and holding the same, agrees 
with the Company and the Trustee that neither the Company nor the Trustee nor 
any Authenticating Agent nor any Paying Agent nor any Security Registrar 
shall be held accountable by reason of the disclosure of any information as 
to the names and addresses of the Holders of Securities in accordance with 
TIA Section 312, regardless of the source from which such information was 
derived, and that the Trustee shall not be held accountable by reason of 
mailing any material pursuant to a request made under TIA Section 312(b). 

         Section 7.2 Reports by Trustee.  Within 60 days after May 15 of each 
year commencing with the first May 15 after the first issuance of Securities 
pursuant to this Indenture, the Trustee shall transmit by mail to all Holders 
of Securities as provided in TIA Section 313(c) a brief report dated as of 
such May 15 if required by TIA Section 3l3(a).  A copy of each such report 
shall at the time of such transmission to Holders be filed by the Trustee 
with each stock exchange upon which any Securities are listed, with the 
Commission and the Company.  The Company will notify the Trustee when any 
securities are listed on any stock exchange. 

         Section 7.3 Reports by Company.  The Company will:

         (1)  file with the Trustee, within 15 days after the Company is
    required to file the same with the Commission, copies of the annual reports
    and of the information, documents and other reports (or copies of such
    portions of any of the foregoing as the Commission may from time to time by
    rules and regulations prescribe) which the Company may be required to file
    with the Commission pursuant to Section 13 or Section 15(d) of the
    Securities Exchange Act of 1934; or, if the Company is not required to file
    information, documents or reports pursuant to either of such Sections, then
    it will file with the Trustee and the Commission, in accordance with rules
    and regulations prescribed from time to 
    

                                                                            56

    time by the Commission, such of the supplementary and periodic information,
    documents and reports which may be required pursuant to Section 13 of the 
    Securities Exchange Act of 1934 in respect of a security listed and 
    registered on a national securities exchange as may be prescribed from time
    to time in such rules and regulations;

         (2)  file with the Trustee and the Commission, in  accordance with
    rules and regulations prescribed from time  to time by the Commission, such
    additional information,  documents and reports with respect to compliance
    by the Company with the conditions and covenants of this Indenture as may
    be required from time to time by such rules and regulations; and

         (3)  transmit by mail to the Holders of Securities, within 30 days
    after the filing thereof with the Trustee, in the manner and to the extent
    provided in TIA Section 3l3(c), such summaries of any information,
    documents and reports required to be filed by the Company pursuant to
    paragraphs (1) and (2) of this Section as may be required by rules and
    regulations prescribed from time to time by the Commission.

         Section 7.4 Company to Furnish Trustee Names and Addresses of 
Holders.  The Company will furnish or cause to be furnished to the Trustee:

         (a)    semi-annually, not later than 15 days after the Regular 
Record Date for interest for each series of Securities, a list, in such form 
as the Trustee may reasonably require, of the names and addresses of the 
Holders of Registered Securities of such series as of such Regular Record 
Date, or if there is no Regular Record Date for interest for such series of 
Securities, semi-annually, upon such dates as are set forth in the Board 
Resolution or indenture supplemental hereto authorizing such series, and 

         (b)    at such other times as the Trustee may request in writing, 
within 30 days after the receipt by the Company of any such request a list of 
similar form and content as of a date not more than 15 days prior to the time 
such list is furnished; 

provided, however, that so long as the Trustee is the Security Registrar, no 
such list shall be required to be furnished. 



                                                                          57

                 CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE

    Section 8.1  CONSOLIDATIONS AND MERGERS OF COMPANY AND SALES, LEASES AND 
CONVEYANCES PERMITTED SUBJECT TO CERTAIN CONDITIONS.  The Company may 
consolidate with, or sell, lease or convey all or substantially all of its 
assets to, or merge with or into any other corporation, provided that in any 
such case, (i) either the Company shall be the continuing corporation, or the 
successor corporation shall be a corporation organized and existing under the 
laws of the United States or a State thereof and such successor corporation 
shall expressly assume the due and punctual payment of the principal of (and 
premium, if any) and any interest (including all Additional Amounts, if any, 
payable pursuant to this Indenture) on all of the Securities, according to 
their tenor, and the due and punctual performance and observance of all of 
the covenants and conditions of this Indenture to be performed by the Company 
by supplemental indenture, complying with Article Nine hereof, satisfactory 
to the Trustee, executed and delivered to the Trustee by such corporation and 
(ii) immediately after giving effect to such transaction and treating any 
indebtedness which becomes an obligation of the Company or any Subsidiary as 
a result thereof as having been incurred by the Company or such Subsidiary at 
the time of such transaction, no Event of Default, and no event which, after 
notice or the lapse of time, or both, would become an Event of Default, shall 
have occurred and be continuing. 

    Section 8.2  RIGHTS AND DUTIES OF SUCCESSOR CORPORATION.  In case of any 
such consolidation, merger, sale, lease or conveyance and upon any such 
assumption by the successor corporation, such successor corporation shall 
succeed to and be substituted for the Company, with the same effect as if it 
had been named herein as the party of the first part, and the predecessor 
corporation, except in the event of a lease, shall be relieved of any further 
obligation under this Indenture and the Securities.  Such successor 
corporation thereupon may cause to be signed, and may issue either in its own 
name or in the name of the Company, any or all of the Securities issuable 
hereunder which theretofore shall not have been signed by the Company and 
delivered to the Trustee; and, upon the order of such successor corporation, 
instead of the Company, and subject to all the terms, conditions and 
limitations in this Indenture prescribed, the Trustee shall authenticate and 
shall deliver any Securities which previously shall have been signed and 
delivered by the officers of the Company to the Trustee for authentication, 
and any Securities which such successor corporation thereafter shall cause to 
be signed and delivered to the Trustee for that purpose.  All the Securities 
so issued shall in all respects have the same legal rank and benefit under 
this Indenture as the Securities theretofore or thereafter issued in 
accordance with the terms of this Indenture as though all of such securities 
had been issued at the date of the execution hereof. 


                                                                      58

    In case of any such consolidation, merger, sale, lease or conveyance,
such changes in phraseology and form (but not in substance) may be made in the
Securities thereafter to be issued as may be appropriate. 

    Section 8.3  OFFICERS' CERTIFICATE AND OPINION OF COUNSEL.  Any 
consolidation, merger, sale, lease or conveyance permitted under Section 8.1 
is also subject to the condition that the Trustee receive an Officers' 
Certificate and an Opinion of Counsel to the effect that any such 
consolidation, merger, sale, lease or conveyance, and the assumption by any 
successor corporation, complies with the provisions of this Article and that 
all conditions precedent herein provided for relating to such transaction 
have been complied with.

                               SUPPLEMENTAL INDENTURES
                                           
    Section 9.1  SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF HOLDERS.  Without 
the consent of any Holders of Securities or coupons, the Company, when 
authorized by or pursuant to a Board Resolution, and the Trustee, at any time 
and from time to time, may enter into one or more indentures supplemental 
hereto, in form satisfactory to the Trustee, for any of the following 
purposes: 

         (1)  to evidence the succession of another Person to the Company and
    the assumption by any such successor of the covenants of the Company herein
    and in the Securities contained; or

         (2)  to add to the covenants of the Company for the benefit of the
    Holders of all or any series of Securities (and if such covenants are to be
    for the benefit of less than all series of Securities, stating that such
    covenants are expressly being included solely for the benefit of such
    series) or to surrender any right or power herein conferred upon the
    Company; or

         (3)  to add any additional Events of Default for the benefit of the
    Holders of all or any series of Securities (and if such Events of Default
    are to be for the benefit of less than all series of Securities stating
    that such Events of Default are expressly being included solely for the
    benefit of such series); provided, however, that in respect of any such
    additional Events of Default such supplemental Indenture may provide for a
    particular period of grace after default (which period may be shorter or
    longer than that allowed in the case of other defaults) or may provide for
    an immediate enforcement upon such default or may limit the remedies
    available to the Trustee upon such default or may limit the right of the
    Holders of a majority in aggregate principal amount of that or those series
    of Securities to which such additional Events of Default apply or waive
    such default; or


                                                                          59

         (4)  to add to or change any of the provisions of this Indenture to
    provide that Bearer Securities may be registrable as to principal, to
    change or eliminate any restrictions on the payment of principal or any
    premium or interest on Bearer Securities, to permit Bearer Securities to be
    issued in exchange for Registered Securities, to permit Bearer Securities
    to be issued in exchange for Bearer Securities of other authorized
    denominations or to permit or facilitate the issuance of Securities in
    uncertificated form, provided that any such action shall not adversely
    affect the interests of the Holders of Securities of any series or any
    related coupons in any material respect; or

         (5)  to change or eliminate any of the provisions of this Indenture,
    provided that any such change or elimination shall become effective only
    when there is no Security Outstanding of any series created prior to the
    execution of such supplemental indenture which is entitled to the benefit
    of such provision; or

         (6)  to secure the Securities; or

         (7)  to establish the form or terms of Securities of any series and
    any related coupons as permitted by Sections 2.1 and 3.1, including the
    provisions and procedures relating to Securities convertible into Common
    Stock or Preferred Stock, as the case may be; or

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

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

         (10) to supplement any of the provisions of this Indenture to such
    extent as shall be necessary to permit or facilitate the defeasance and
    discharge of any series of Securities pursuant to Sections 4.1, 14.2 and
    14.3; provided that any such action shall not adversely affect the
    interests of the Holders of Securities of such series and any related
    coupons or any other series of Securities in any material respect.


                                                                          60

    Section 9.2  SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.  With the 
consent of the Holders of not less than a majority in principal amount of all 
Outstanding Securities affected by such supplemental indenture, by Act of 
said Holders delivered to the Company and the Trustee, the Company, when 
authorized by or pursuant to a Board Resolution, and the Trustee may enter 
into an indenture or indentures supplemental hereto for the purpose of adding 
any provisions to or changing in any manner or eliminating any of the 
provisions of this Indenture or of modifying in any manner the rights of the 
Holders of Securities and any related coupons under this Indenture; provided, 
however, that no such supplemental indenture shall, without the consent of 
the Holder of each Outstanding Security affected thereby: 

         (1)  change the Stated Maturity of the principal of (or premium, if
    any, on) or any installment of principal of or interest on, any Security;
    or reduce the principal amount thereof or the rate or amount of interest
    thereon or any Additional Amounts payable in respect thereof, or any
    premium payable upon the redemption thereof, or change any obligation of
    the Company to pay Additional Amounts pursuant to Section 10.8 (except as
    contemplated by Section 8.1(1) and permitted by Section 9.1(1)), or reduce
    the amount of the principal of an Original Issue Discount Security) that
    would be due and payable upon a declaration of acceleration of the Maturity
    thereof pursuant to Section 5.2 or the amount thereof provable in
    bankruptcy pursuant to Section 5.4, or adversely affect any right of
    repayment at the option of the Holder of any Security, or change any Place
    of Payment where, or the currency or currencies, currency unit or units or
    composite currency or currencies in which, any Security or any premium or
    the interest thereon is payable, or impair the right to institute suit for
    the enforcement of any such payment on or after the Stated Maturity thereof
    (or, in the case of redemption or repayment at the option of the Holder, on
    or after the Redemption Date or the Repayment Date, as the case may be), or

         (2)  reduce the percentage in principal amount of the Outstanding
    Securities of any series, the consent of whose Holders is required for any
    such supplemental indenture, or the consent of whose Holders is required
    for any waiver with respect to such series (or compliance with certain
    provisions of this Indenture or certain defaults hereunder and their
    consequences) provided for in this Indenture, or reduce the requirements of
    Section 15.4 for quorum or voting, or

         (3)  modify any of the provisions of this Section, Section 5.13 or
    Section 10.8, except to increase the required percentage to effect such
    action 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.


                                                                          61

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

    A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which has expressly been included 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.

    Section 9.3  EXECUTION OF SUPPLEMENTAL INDENTURES.  In executing, or 
accepting the additional trusts created by, any supplemental indenture 
permitted by this Article or the modification thereby of the trusts created 
by this Indenture, the Trustee shall be entitled to receive, and 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 9.4  EFFECT OF SUPPLEMENTAL INDENTURES.  Upon the execution of any
supplemental indenture under this Article, this Indenture shall be modified in

Indenture for all purposes; and every Holder of Securities theretofore or
thereafter authenticated and delivered hereunder and of any coupon appertaining
thereto shall be bound thereby. 

    Section 9.5  CONFORMITY WITH TRUST INDENTURE ACT.  Every supplemental 
indenture executed pursuant to this Article shall conform to the requirements 
of the Trust Indenture Act as then in effect. 

    Section 9.6  REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.  
Securities 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 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 10.1  PAYMENT OF PRINCIPAL, PREMIUM, IF ANY, INTEREST AND 
ADDITIONAL AMOUNTS.  The Company covenants and agrees for the benefit of the 
Holders of each series of Securities that it will duly and punctually pay the 
principal of (and premium, if any) and interest on and any Additional Amounts 
payable in respect of the Securities of that series in accordance with the 
terms of such series of Securities, any coupons appertaining thereto and this 
Indenture. Unless otherwise specified as contemplated by Section 3.1 with 
respect to any series of Securities, any interest due on and any Additional 
Amounts payable in respect of Bearer Securities on or before Maturity, other

respect of principal of (or premium, if any, on) such a Security, shall be 
payable only upon presentation and surrender of the several coupons for such 
interest installments as are evidenced thereby as they severally mature.  
Unless otherwise specified with respect to Securities of any series pursuant 
to Section 3.1, at the option of the Company, all payments of principal may 
be paid by check to the registered Holder of the Registered Security or other 
person entitled thereto against surrender of such Security. 

    Section 10.2  MAINTENANCE OF OFFICE OR AGENCY.  If Securities of a series 
are issuable only as Registered Securities, the Company shall maintain in 
each Place of Payment for any series of Securities an office or agency where 
Securities of that series may be presented or surrendered for payment or 
conversion, where Securities of that series may be surrendered for 
registration of transfer or exchange and where notices and demands to or upon 
the Company in respect of the Securities of that series and this Indenture 
may be served.  If Securities of a series are issuable as Bearer Securities, 
the Company will maintain:  (A) in the Borough of Manhattan, The City of New 
York, an office or agency where any Registered Securities of that series may 
be presented or surrendered for payment or conversion, where any Registered 
Securities of that series may be surrendered for registration of transfer, 
where Securities of that series may be surrendered for exchange, where 
notices and demands to or upon the Company in respect of the Securities of 
that series and this Indenture may be served and where Bearer Securities of 
that series and related coupons may be presented or surrendered for payment 
or conversion in the circumstances described in the following paragraph (and 
not otherwise); (B) subject to any laws or regulations applicable thereto, in 
a Place of Payment for that series which is located outside the United 
States, an office or agency where Securities of that series and related 
coupons may be presented and surrendered for payment (including payment of 
any Additional Amounts payable on Securities of that series pursuant to 
Section 10.8) or conversion; provided, however, that if the Securities of 
that series are listed on the Luxembourg Stock Exchange or any other stock 
exchange located outside the United States and such stock exchange 



                                                                          63

shall so require, the Company will maintain a Paying Agent for the Securities 
of that series in Luxembourg or any other required city located outside the 
United States, as the case may be, so long as the Securities of that series 
are listed on such exchange; and (C) subject to any laws or regulations 
applicable thereto, in a Place of Payment for that series located outside the 
United States an office or agency where any Registered Securities of that 
series may be surrendered for registration of transfer, where Securities of 
that series may be surrendered for exchange and where notices and demand to 
or upon the Company in respect of the Securities of that series and this 
Indenture may be served.  The Company will give prompt written notice to the 
Trustee of the location, and any change in the location, of each such office 
or agency. If at any time the Company shall fail to maintain any such 
required office or agency or shall fail to furnish the Trustee with the 
address thereof, such presentations, surrenders, notices and demands may be 
made or served at the Corporate Trust Office of the Trustee, except that 
Bearer Securities of that series and the related coupons may be presented and 
surrendered for payment (including payment of any Additional Amounts payable 
on Bearer Securities of that series pursuant to Section 10.8) or conversion 
at the offices specified in the Security, in London, England, and the Company 
hereby appoints the same as its agent to receive such presentations, 
surrenders, notices and demands, and the Company hereby appoints the Trustee 
its agent to receive all such presentations, surrenders, notices and demands.

    Unless otherwise specified with respect to any Securities pursuant to 
Section 3.1, no payment of principal, premium or interest on or Additional 
Amounts in respect of Bearer Securities shall be made at any office or agency 
of the Company 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, that, if the Securities of a series are 
payable in Dollars, payment of principal of and any premium and interest on 
any Bearer Security (including any Additional Amounts payable on Securities 
of such series pursuant to Section 10.8) shall be made at the office of the 
Company's Paying Agent in the Borough of Manhattan, The City of New York, if 
(but only if) payment in Dollars of the full amount of such principal, 
premium, interest or Additional Amounts, as the case may be, at all offices 
or agencies outside the United States maintained for the purpose by the 
Company in accordance with this Indenture, is illegal or effectively 
precluded by exchange controls or other similar restrictions. 

    The Company may from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all of such purposes, and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in accordance with the requirements set forth above for Securities of
any series for such purposes.  The Company will give prompt written notice to
the Trustee of any such designation or rescission and of any change in the
location of any such other office or agency.  Unless otherwise specified with
respect to any Securities pursuant to 



                                                                          64

Section 3.1 with respect to a series of Securities, the Company hereby 
designates as a Place of Payment for each series of Securities the office or 
agency of the Company in the Borough of Manhattan, The City of New York, and 
initially appoints the Trustee at its Corporate Trust Office as Paying Agent 
in such city and as its agent to receive all such presentations, surrenders, 
notice and demands. 

    Unless otherwise specified with respect to any Securities pursuant to
Section 3.1, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of the Indenture, then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one exchange rate agent. 

    Section 10.3  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 any Securities and any related coupons, it will, on or before each 
due date of the principal of (and premium, if any), or interest on or 
Additional Amounts in respect of, any of the Securities of that series, 
segregate and hold in trust for the benefit of the Persons entitled thereto a 
sum in the currency or currencies, currency unit or units or composite 
currency or currencies in which the Securities of such series are payable 
(except as otherwise specified pursuant to Section 3.1 for the Securities of 
such series) sufficient to pay the principal (and premium, if any) or 
interest or Additional Amounts so becoming due until such sums shall be paid 
to such Persons or otherwise disposed of as herein provided, and will 
promptly notify the Trustee of its action or failure so to act. 

    Whenever the Company shall have one or more Paying Agents for any
series of Securities and any related coupons, it will, on or before each due
date of the principal of (and premium, if any), or interest on or Additional
Amounts in respect of, any Securities of that series, deposit with a Paying
Agent a sum (in the currency or currencies, currency unit or units or composite
currency or currencies described in the preceding paragraph) sufficient to pay
the principal (and premium, if any) or interest or Additional Amounts, so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest or Additional Amounts 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 will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will 

         (1)  hold all sums held by it for the payment of principal of (and
    premium, if any) or interest on Securities or Additional Amounts in trust
    for 



                                                                          65

    the benefit of the Persons entitled thereto until such sums shall be
    paid to such Persons or otherwise disposed of as herein provided;

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

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

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

    Except as otherwise provided in the Securities of any series, any
money deposited with the Trustee or any Paying Agent, or then held by the
Company, in trust for the payment of the principal of (and premium, if any) or
interest on, or any Additional Amounts in respect of, any Security of any series
and remaining unclaimed for two years after such principal (and premium, if
any), interest or Additional Amounts has become due and payable shall be paid to
the Company upon Company Request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Security shall thereafter, as
an unsecured general creditor, look only to the Company for payment of such
principal of (and premium, if any) or interest on, or any Additional Amounts in
respect of, any Security, without interest thereon, 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, notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of
such publication, any unclaimed balance of such money then remaining will be
repaid to the Company. 

    Section 10.4  EXISTENCE.  Subject to Article Eight, the Company will do 
or cause to be done all things necessary to preserve and keep in full force 
and effect its corporate existence, rights (charter and statutory) and 
franchises, except to the extent the failure to do so would not have a 
material adverse effect on the business, assets, financial condition or 
results of operations of the Company (a "Material Adverse Effect"); provided, 
however, that the Company shall not be required to preserve any right or 
franchise if the Board of Directors shall determine that the 


                                                                          66

preservation thereof is no longer desirable in the conduct of the business of 
the Company. 

    Section 10.5  MAINTENANCE OF PROPERTIES.  The Company will cause all of 
it properties used or useful in the conduct of its business or the business 
of any Subsidiary to be maintained and kept in good condition, repair and 
working order and supplied with all necessary equipment and will cause to be 
made all necessary repairs, renewals, replacements, betterments and 
improvements thereof, all as in the judgment of the Company may be necessary 
so that the business carried on in connection therewith may be properly and 
advantageously conducted at all times, except to the extent the failure to do 
so would not have a Material Adverse Effect on the Company; provided, 
however, that the Company shall not be required to continue the operation or 
maintenance of any such property or be prevented from disposing of such 
property if the Board of Directors shall determine that such discontinuance 
or disposal is desirable in the conduct of the business of the Company.

    Section 10.6  PAYMENT OF TAXES AND OTHER CLAIMS.  The Company will pay or 
discharge or cause to be paid or discharged, before the same shall become 
delinquent, (1) all taxes, assessments and governmental charges levied or 
imposed upon it or any Subsidiary or upon the income, profits or property of 
the Company or any Subsidiary, and (2) all lawful claims for labor, materials 
and supplies which, if unpaid, might by law become a lien upon the property 
of the Company or any Subsidiary and have a Material Adverse Effect; 
provided, however, that the Company shall not be required to pay or discharge 
or cause to be paid or discharged any such tax, assessment, charge or claim 
whose amount, applicability or validity is being contested in good faith by 
appropriate proceedings. 

    Section 10.7  STATEMENT AS TO COMPLIANCE.  The Company will deliver to 
the Trustee, within 120 days after the end of each fiscal year, a brief 
certificate from the principal executive officer, principal financial officer 
or principal accounting officer as to his or her knowledge of the Company's 
compliance with all conditions and covenants under this Indenture and, in the 
event of any noncompliance, specifying such noncompliance and the nature and 
status thereof. For purposes of this Section 10.7, such compliance shall be 
determined without regard to any period of grace or requirement of notice 
under this Indenture. 

    Section 10.8  ADDITIONAL AMOUNTS.  If any Securities of a series provide 
for the payment of Additional Amounts, the Company will pay to the Holder of 
any Security of such series or any coupon appertaining thereto Additional 
Amounts as may be specified as contemplated by Section 3.1.  Whenever in this 
Indenture there is mentioned, in any context except in the case of Section 
5.2(1), the payment of the principal of or any premium or interest on, or in 
respect of, any Security of any series or payment of any related coupon or 
the net proceeds received on the sale or exchange of any Security of any 
series, such mention shall be deemed to include 


                                                                          67

mention of the payment of Additional Amounts provided by the terms of such 
series established pursuant to Section 3.1 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 provisions hereof shall not be construed as 
excluding Additional Amounts in those provisions hereof where such express 
mention is not made. 

    Except as otherwise specified as contemplated by Section 3.1, 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 that 
series of Securities or if the Securities of that series will not bear 
interest prior to Maturity, the first day on which a payment of principal and 
any premium is made, and at least 10 days prior to each date of payment of 
principal and any premium or interest if there has been any change with 
respect to the matters set forth in the below-mentioned Officers' 
Certificate, the Company will furnish the Trustee and the Company's principal 
Paying Agent or Paying Agents, if other than the Trustee, with an Officers' 
Certificate instructing the Trustee and such Paying Agent or Paying Agents 
whether such payment of principal of and any premium or interest on the 
Securities of that series shall be made to Holders of Securities of that 
series or any related coupons who are not United States persons without 
withholding for or on account of any tax, assessment or other governmental 
charge described in the Securities of the 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 of that series or related coupons and the Company will pay to 
the Trustee or such Paying Agent the Additional Amounts required by the terms 
of such Securities.  In the event that the Trustee or any Paying Agent, as 
the case may be, shall not so receive the above-mentioned certificate, then 
the Trustee or such Paying Agent shall be entitled (i) to assume that no such 
withholding or deduction is required with respect to any payment of principal 
or interest with respect to any Securities of a series or related coupons 
until it shall have received a certificate advising otherwise and (ii) to 
make all payments of principal and interest with respect to the Securities of 
a series or related coupons without withholding or deductions until otherwise 
advised.  The Company covenants to indemnify the Trustee and any Paying Agent 
for, and to hold them harmless against, any loss, liability or expense 
reasonably incurred without negligence or bad faith on their part arising out 
of or in connection with actions taken or omitted by any of them or in 
reliance on any Officers' Certificate furnished pursuant to this Section or 
in reliance on the Company's not furnishing such an Officers' Certificate. 

    Section 10.9  WAIVER OF CERTAIN COVENANTS.  The Company may omit in any 
particular instance to comply with any term, provision or condition set forth 
in Sections 10.4 to 10.6, inclusive, if before or after the time for such 
compliance the Holders of at least a majority in principal amount of all 
outstanding Securities of such series, by Act of such Holders, either waive 
such compliance in such instance or generally waive compliance with such 
covenant or condition, but no such waiver shall 


                                                                          68

extend to or affect such covenant or condition except to the extent so 
expressly waived, and, until such waiver shall become effective, the 
obligations of the Company and the duties of the Trustee in respect of any 
such term, provision or condition shall remain in full force and effect. 

                                     ARTICLE 11

                               REDEMPTION OF SECURITIES
                                           
    Section 11.1  APPLICABILITY OF ARTICLE.  Securities of any series which 
are redeemable before their Stated Maturity shall be redeemable in accordance 
with their terms and (except as otherwise specified as contemplated by 
Section 3.1 for Securities of any series) in accordance with this Article. 

    Section 11.2  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, at least 45 days 
prior to the giving of the notice of redemption in Section 11.4 (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.  In the case of any redemption of Securities prior to the 
expiration of any restriction on such redemption provided in the terms of 
such Securities or elsewhere in this Indenture, the Company shall furnish the 
Trustee with an Officers' Certificate evidencing compliance with such 
restriction. 

    Section 11.3  SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.  If less 
than all the Securities of any series issued on the same day with the same 
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 issued on such date with the 
same terms 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 (equal the minimum authorized 
denomination for Securities of that series or any integral multiple thereof) 
of the principal amount of Securities of such series of a denomination larger 
than the minimum authorized denomination for Securities of that series. 

    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 


                                                                          69

of any Security redeemed or to be redeemed only in part, to the portion of 
the principal amount of such Security which has been or is to be redeemed. 

    Section 11.4  NOTICE OF REDEMPTION.  Notice of redemption shall be given 
in the manner provided in Section 1.6, not less than 30 days nor more than 60 
days prior to the Redemption Date, unless a shorter period is specified by 
the terms of such series established pursuant to Section 3.1, to each Holder 
of Securities to be redeemed, but failure to give such notice in the manner 
herein provided to the Holder of any Security 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 such 
Security or portion thereof. 

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

    All notices of redemption shall state

         (1)  the Redemption Date,

         (2)  the Redemption Price, accrued interest to the Redemption Date
payable as provided in Section 11.6, if any, and Additional Amounts, if any, 

         (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 will receive, without a
charge, a new Security or Securities of authorized denominations for the
principal amounts thereof remaining unredeemed, 

         (5)  that on the Redemption Date the Redemption Price and accrued
interest to the Redemption Date payable as provided in Section 11.6, if any,
will become due and payable upon each such Security, or the 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 of Payment 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 accrued interest, if any, or for conversion,

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


                                                                          70

         (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 for such series 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 this Redemption Date pursuant to Section 3.5 or otherwise, the Last date, as
determined by the Company, on which such exchanges may be made, 

         (10)  the CUSIP number of such Security, if any, and

         (11)  if applicable, that a Holder of Securities who desires to
convert Securities for redemption must satisfy the requirements for conversion
contained in such Securities, the then existing conversion price or rate, and
the date and time when the option to convert shall expire. 

         Notice of redemption of Securities to be redeemed 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 11.5  DEPOSIT OF REDEMPTION PRICE.  At least one Business Day 
prior to any Redemption Date, the Company shall deposit with the Trustee or 
with a Paying Agent (or, if the Company is acting as its own Paying Agent, 
which it may not do in the case of a sinking fund payment under Article 
Twelve, segregate and hold in trust as provided in Section 10.3) an amount of 
money in the currency or currencies, currency unit or units or composite 
currency or currencies in which the Securities of such series are payable 
(except as otherwise specified pursuant to Section 3.1 for the Securities of 
such series) sufficient to pay on the Redemption Date the Redemption Price 
of, and (except if the Redemption Date shall be an Interest Payment Date) 
accrued interest on, all the Securities or portions thereof which are to be 
redeemed on that date. 

    Section 11.6  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 in the currency or currencies, currency unit or units or 
composite currency or currencies in which the Securities of such series are 
payable (except as otherwise specified pursuant to Section 3.1 for the 
Securities of such series) (together with accrued interest, if any, to the 
Redemption Date), and from and after such date (unless the Company shall 
default in the payment of the Redemption Price and 


                                                                          71

accrued interest) such Securities shall, if the same were interest-bearing, 
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 accrued interest, if any, 
to the Redemption Date; provided, however, that installments of interest on 
Bearer Securities whose Stated Maturity is on or prior to the Redemption Date 
shall be payable only at an office or agency located outside the United 
States (except as otherwise provided in Section 10.2) and, unless otherwise 
specified as contemplated by Section 3.1, only upon presentation and 
surrender of coupons for such interest; and provided further that, except as 
otherwise provided with respect to Securities convertible into Common Stock 
or Preferred Stock, 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 relevant Record Dates according to 
their terms and the provisions of Section 3.7.

    If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Company and the Trustee if there be
furnish 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 interest represented by coupons shall be payable only at an office
or agency located outside the United States (except as otherwise provided in
Section 10.2) and unless otherwise specified as contemplated by Section 3.1,
only upon presentation and surrender of those coupons. 

    If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate borne by the
Security.

    Section 11.7  SECURITIES REDEEMED IN PART.  Any Registered Security which 
is to be redeemed only in part (pursuant to the provisions of this Article or 
of Article Twelve) shall be surrendered at a Place of Payment therefor (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 
duty 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 Security 
or Securities of the same series, of any authorized 


                                                                          72

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.

                                   SINKING FUNDS
                                           
    Section 12.1  APPLICABILITY OF ARTICLE.  The provisions of this Article 
shall be applicable to any sinking fund for the retirement of Securities of a 
series except as otherwise specified as contemplated by Section 3.1 for 
Securities of such series.

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

    Section 12.2  SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.  The 
Company may, in satisfaction of all or any part of any mandatory sinking fund 
payment with respect to the Securities of a series, (1) deliver Outstanding 
Securities of such series (other than any previously called for redemption) 
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 Securities or through the application of 
permitted optional sinking fund payments pursuant to the terms of such 
Securities, as provided for by the terms of such Securities, or which have 
otherwise been acquired by the Company; provided that such Securities so 
delivered or applied as a credit have not been previously so credited.  Such 
Securities shall be received and credited for such purpose by the Trustee at 
the applicable Redemption Price specified in such Securities for redemption 
through operation of the sinking fund and the amount of such mandatory 
sinking fund payment shall be reduced accordingly. 

    Section 12.3  REDEMPTION OF SECURITIES FOR SINKING FUND.  Not less than 
60 days prior to each sinking fund payment date for Securities of any series, 
the Company will 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 in the currency or currencies, currency 
unit or units or composite currency or 


                                                                          73

currencies in which the Securities of such series are payable (except as 
otherwise specified pursuant to Section 3.1 for the Securities of such 
series) and the portion thereof, if any, which is to be satisfied by 
delivering and crediting Securities of that series pursuant to Section 12.2, 
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 delivered and credited.  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 30 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 11.3 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 
11.4.  Such notice having been duly given, the redemption of such Securities 
shall be made upon the terms and in the manner stated in Sections 11.6 and 
11.7. 

                                     ARTICLE 13

                          REPAYMENT AT THE OPTION OF HOLDERS
                                           
    Section 13.1  APPLICABILITY OF ARTICLE.  Repayment of Securities of any 
series before their Stated Maturity at the option of Holders thereof shall be 
made in accordance with the terms of such Securities, if any, and (except as 
otherwise specified by the terms of such series established pursuant to 
Section 3.1) in accordance with this Article. 

    Section 13.2  REPAYMENT OF SECURITIES.  Securities of any series subject 
to repayment in whole or in part at the option of the Holders thereof will, 
unless otherwise provided in the terms of such Securities, be repaid at a 
price equal to the principal amount thereof, together with interest, if any, 
thereon accrued to the Repayment Date specified in or pursuant to the terms 
of such Securities. The Company covenants that at least one Business Day 
prior to the Repayment Date it will deposit 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 10.3) an amount of money in the currency 
or currencies, currency unit or units or composite currency or currencies in 
which the Securities of such series are payable (except as otherwise 
specified pursuant to Section 3.1 for the Securities of such series) 
sufficient to pay the principal (or, if so provided by the terms of the 
Securities of any series, a percentage of the principal) of, and (except if 
the Repayment Date shall be an Interest Payment Date) accrued interest on, 
all the Securities or portions thereof, as the case may be, to be repaid on 
such date. 

    Section 13.3  EXERCISE OF OPTION.  Securities of any series subject to 
repayment at the option of the Holders thereof will contain an "Option to 
Elect 


                                                                          74

Repayment" form on the reverse of such Securities.  In order for any 
Security to be repaid at the option of the Holder, the Trustee must receive 
at the Place of Payment therefor specified in the terms of such Security (or 
at such other place or places of which the Company shall from time to time 
notify the Holders of such Securities) not earlier than 60 days nor later 
than 30 days prior to the Repayment Date (1) the Security so providing for 
such repayment together with the "Option to Elect Repayment" form on the 
reverse thereof duly completed by the Holder (or by the Holder's attorney 
duly authorized in writing) or (2) a telegram, telex, facsimile transmission 
or a letter from a member of a national securities exchange, or the National 
Association of Securities Dealers, Inc. ("NASD"), or a commercial bank or 
trust company in the United States setting forth the name of the Holder of 
the Security, the principal amount of the Security, the principal amount of 
the Security to be repaid, the CUSIP number, if any, or a description of the 
tenor and terms of the Security, a statement that the option to elect 
repayment is being exercised thereby and a guarantee that the Security to be 
repaid, together with the duly completed form entitled "Option to Elect 
Repayment" on the reverse of the Security, will be received by the Trustee 
not later than the fifth Business Day after the date of such telegram, telex, 
facsimile transmission or letter; provided, however, that such telegram, 
telex, facsimile transmission or letter shall only be effective if such 
Security and form duly completed are received by the Trustee by such fifth 
Business Day.  If less than the entire principal amount of such Security is 
to be repaid in accordance with the terms of such Security, the principal 
amount of such Security to be repaid, in increments of the minimum 
denomination for Securities of such series, and the denomination or 
denominations of the Security or Securities to be issued to the Holder for 
the portion for the principal amount of such Security surrendered that is not 
to be repaid, must be specified. The principal amount of any Security 
providing for repayment at the option of the Holder thereof may not be repaid 
in part if, following such repayment, the unpaid principal amount of such 
Security would be less than the minimum authorized denomination of Securities 
of the series of which such Security to be repaid is a part.  Except as 
otherwise may be provided by the terms of any Security providing for 
repayment at the option of the Holder thereof, exercise of the repayment 
option by the Holder shall be irrevocable unless waived by the Company. 

    Section 13.4  WHEN SECURITIES PRESENTED FOR REPAYMENT BECOME DUE AND 
PAYABLE.  If Securities of any series providing for repayment at the option 
of the Holders thereof shall have been surrendered as provided in this 
Article and as provided by or pursuant to the terms of such Securities, such 
Securities or the portions thereof, as the case may be, to be repaid shall 
become due and payable and shall be paid by the Company on the Repayment Date 
therein specified, and on and after such Repayment Date (unless the Company 
shall default in the payment of such Securities on such Repayment Date) such 
Securities shall, if the same were interest-bearing, cease to bear interest 
and the coupons for such interest appertaining to any Bearer Securities so to 
be repaid, except to the extent provided below, shall be void.  Upon 
surrender of any such Security for repayment in accordance with such 
provisions, together with all coupons, if any, appertaining thereto maturing 
after the 


                                                                          75

Repayment Date, the principal amount of such Security so to be repaid shall 
be paid by the Company, together with accrued interest, if any, to the 
Repayment Date; provided, however, that coupons whose Stated Maturity is on 
or prior to the Repayment Date shall be payable only at an office or agency 
located outside the United States (except as otherwise provided in Section 
10.2) and, unless otherwise specified pursuant to Section 3.1, only upon 
presentation and surrender of such coupons; and provided further that, in the 
case of Registered Securities, installments of interest, if any, whose Stated 
Maturity is on or prior to the Repayment Date shall be payable (but without 
interest thereon, unless the Company shall default in the payment thereof) to 
the Holders of such Securities, or one or more Predecessor Securities, 
registered as such at the close of business on the relevant Record Dates 
according to their terms and the provisions of Section 3.7. 

    If any Bearer Security surrendered for repayment shall not be accompanied 
by all appurtenant coupons maturing after the Repayment Date, such Security 
may be paid after deducting from the amount payable therefor as provided in 
Section 13.2 an amount equal to the face amount of all such missing coupons, 
or the surrender of such missing coupon or coupons may be waived by the 
Company and the Trustee if there be furnished to them such security or 
indemnity as they may require to save each of them and any Paying Agent 
harmless.  If thereafter the Holder of such Security shall surrender to the 
Trustee or any Paying Agent any such missing coupon in respect of which a 
deduction shall have been made as provided in the preceding sentence, such 
Holder shall be entitled to receive the amount so deducted; provided, 
however, that interest represented by coupons shall be payable only at an 
office or agency located outside the United States (except as otherwise 
provided in Section 10.2) and, unless otherwise specified as contemplated by 
Section 3.1, only upon presentation and surrender of those coupons. 

    If the principal amount of any Security surrendered for repayment shall 
not be so repaid upon surrender thereof, such principal amount (together with 
interest, if any, thereon accrued to such Repayment Date) shall, until paid, 
bear interest from the Repayment Date at the rate of interest or Yield to 
Maturity (in the case of Original Issue Discount Securities) set forth in 
such Security. 

    Section 13.5  SECURITIES REPAID IN PART.  Upon surrender of any 
Registered Security which is to be repaid in part only, the Company shall 
execute and the Trustee shall authenticate and deliver to the Holder of such 
Security, without service charge and at the expense of the Company a new 
Registered Security or Securities of the same series, of any authorized 
denomination specified by the Holder, in an aggregate principal amount equal 
to and in exchange for the portion of the principal of such Security so 
surrendered which is not to be repaid. 

                                           

                                                                          76

                          DEFEASANCE AND COVENANT DEFEASANCE

    Section 14.1  APPLICABILITY OF ARTICLE; COMPANY'S OPTION TO EFFECT 
DEFEASANCE OR COVENANT DEFEASANCE.  If, pursuant to Section 3.1, provision is 
made for either or both of (a) defeasance of the Securities of or within a 
series under Section 14.2 or (b) covenant defeasance of the Securities of or 
within a series under Section 14.3, then the provisions of such Section or 
Sections, as the case may be, together with the other provisions of this 
Article (with such modifications thereto as may be specified pursuant to 
Section 3.1 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 14.2 (if applicable) 
or Section 14.3 (if applicable) be applied to such Outstanding Securities and 
any coupons appertaining thereto upon compliance with the conditions set 
forth below in this Article. 

    Section 14.2  DEFEASANCE AND DISCHARGE.  Upon the Company's exercise of 
the above option applicable to this Section 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 Section 14.4 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 Section 14.5 and the other Sections of this 
Indenture referred to in clauses (A) and (B) 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 the 
Company, shall execute proper instruments acknowledging the same), except for 
the following which shall survive until otherwise terminated or discharged 
hereunder: (A) the rights of Holders of such Outstanding Securities and any 
coupons appertaining thereto to receive, solely from the trust fund described 
in Section 14.4 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 
such Securities and any coupons appertaining thereto when such payments are 
due, (B) the Company's obligations with respect to such Securities under 
Sections 3.5, 3.6, 10.2 and 10.3 and with respect to the payment of 
Additional Amounts, if any, on such Securities as contemplated by Section 
10.8, (C) the rights, powers, trusts, duties and immunities of the Trustee 
hereunder and (D) this Article.  Subject to compliance with this Article 
Fourteen, the Company may exercise its option under this Section 
notwithstanding the prior exercise of its option under Section 14.3 with 
respect to such Securities and any coupons appertaining thereto. 



                                                                          77

    Section 14.3  COVENANT DEFEASANCE.  Upon the Company's exercise of the 
above option applicable to this Section with respect to any Securities of or 
within a series, the Company shall be released from its obligations under 
Sections 10.4 to 10.6, inclusive, and, if specified pursuant to Section 3.1, 
its obligations under any other covenant, with respect to such Outstanding 
Securities and any coupons appertaining thereto on and after the date the 
conditions set forth in Section 14.4 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 Sections 10.4 to 10.6, 
inclusive, or such other 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 5.1(4) or 5.1(8) or otherwise, as the case may be, but, except 
as specified above, the remainder of this Indenture and such Securities and 
any coupons appertaining thereto shall be unaffected thereby. 

    Section 14.4  CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.  The 
following shall be the conditions to application of Section 14.2 or Section 
14.3 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 6.7 who shall agree to comply with the provisions of this Article 
Fourteen applicable to it) as trust funds in trust for the purpose of making 
the following payments, specifically pledged as security for, and dedicated 
solely to, the benefit of the Holders of such Securities and any coupons 
appertaining  thereto, (1) an amount in such currency, currencies or currency 
unit 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, currencies or currency unit 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 


                                                                          78

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, (i) the principal of (and premium, if any) and interest, if 
any, on such Outstanding Securities and any coupons appertaining thereto on 
the Stated Maturity of such principal or installment of principal or interest 
and (ii) any mandatory sinking fund payments or analogous payments applicable 
to such Outstanding Securities and any coupons appertaining thereto on the 
day on which such payments are due and payable in accordance with the terms 
of  this Indenture and of such Securities and any coupons appertaining 
thereto. 

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

            (c)  No Event of Default or event which with notice or lapse of 
time or both would become an Event of Default with respect to such Securities 
and any coupons appertaining thereto shall have occurred and be continuing on 
the date of such deposit or, insofar as Sections 5.1(6) and 5.1(7) are 
concerned, at any time during the period ending on the 91st day after the 
date of such deposit (it being understood that this condition shall not be 
deemed satisfied until the expiration of such period). 

            (d)  In the case of an election under Section 14.2, the Company 
shall have delivered to the Trustee an Opinion of Counsel stating that (i) 
the Company has received from, or there has been published by, the Internal 
Revenue Service a ruling, or (ii) since the date of execution of this 
Indenture, there has been a change in the applicable Federal income tax law, 
in either case to the effect that, and based thereon such opinion shall 
confirm 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 and will be subject to 
Federal Income tax on the same amounts, in the same manner and at the same 
times as would have been the case if such defeasance had not occurred. 

            (e)  In the case of an election under Section 14.3, 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 covenant defeasance and will be subject to 
Federal income tax on the same amounts, in the same manner and at the same 
times as would have been the case if such covenant defeasance had not 
occurred. 

            (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 under 


                                                                          79

Section 14.2 or the covenant defeasance under Section 14.3 (as the case may 
be) have been complied with and an Opinion of Counsel to the effect that 
either (i) as a result of a deposit pursuant to subsection (a) above and the 
related exercise of the Company's option under Section 14.2 or Section 14.3 
(as the case may be), registration is not  required under the Investment 
Company Act of 1940, as  amended, by the Company, with respect to the trust 
funds representing such deposit or by the Trustee for such trust funds or 
(ii) all necessary registrations under said Act  have been effected. 

            (g)  Notwithstanding any other provisions of this Section, 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 3.1. 

    Section 14.5  DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD IN 
TRUST; OTHER MISCELLANEOUS PROVISIONS.  Subject to the provisions of the last 
paragraph of Section 10.3, all money and Government Obligations (or other 
property as may be provided pursuant to Section 3.1) (including the proceeds 
thereof) deposited with the Trustee (or other qualifying trustee, 
collectively for purposes of this Section 14.5, the "Trustee") pursuant to 
Section 14.4 in respect of 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 with respect to any Security pursuant to 
Section 3.1, if, after a deposit referred to in Section 14.4(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 3.1 or the terms of such 
Security to receive payment in a currency or currency unit other than that in 
which the deposit pursuant to Section 14.4(a) has been made in respect of 
such Security, or (b) a Conversion Event occurs in respect of the currency or 
currency unit in which the deposit pursuant to Section 14.4(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 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 or currency unit in which such Security 
becomes payable as a result of such election or Conversion Event based on the 
applicable market exchange rate for such currency or currency unit in effect 
on the second Business Day prior to each 


                                                                          80

payment date, except, with respect to a Conversion Event, for such currency 
or currency unit in effect (as nearly as feasible) at the time of the 
Conversion Event. 

    The Company shall pay and indemnify the Trustee against any tax, fee or 
other charge imposed on or assessed against the Government Obligations 
deposited pursuant to Section 14.4 or the principal and interest received in 
respect thereof other than any such tax, fee or other charge which by law is 
for the account of the Holders of such Outstanding Securities and any coupons 
appertaining thereto. 

    Anything in this Article to the contrary notwithstanding, subject to 
Section 6.6, 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 Section 14.4 
which, in the opinion of a nationally recognized firm of independent public 
accountants expressed in a written certification thereof delivered to the 
Trustee, 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 Article. 

                               *   *   *  *  *


                                                                          81

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

         IN WITNESS WHEREOF, the parties hereto have caused this Indenture to
be duly executed all as of the day and year first above written.
