          Upon any application or request by the Company to the Trustee to
take any action under any provision of this Indenture, the Company shall
furnish to the Trustee such certificates and opinions as may be required under
the Trust Indenture Act.  Each such certificate or opinion shall be given in

with the requirements of the Trust Indenture Act and any other requirements
set forth in this Indenture.

          Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include

          (1)  a statement that each individual signing such certificate or
     opinion has read such covenant or condition and the definitions herein

Section 103.   FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

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

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

          Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

Section 104.   ACTS OF HOLDERS; RECORD DATES.

          Any request, demand, authorization, direction, notice, consent,
waiver or other action provided or permitted by this Indenture to be given or
taken by Holders may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Holders in person or by agent
duly appointed in writing.  If, but only if, Securities of a series are
issuable as Bearer Securities, any request, demand, authorization, direction,
notice, consent, waiver or other action provided 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 such series duly called
and held in accordance with the provisions of Article Fourteen, 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,

                                       10
20
where it is hereby expressly required, to the Company.  Such instrument or
instruments and any such record (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments or so voting at any such meeting.  Proof of
execution of any such instrument or of a writing appointing any such agent, or
of the holding by any Person of a Security, shall be sufficient for any
purpose of this Indenture and (subject to Section 601) conclusive in favor of
the Trustee and the Company and any agent of the Trustee or the Company, if
made in the manner provided in this Section.  The record of any meeting of
Holders of Securities shall be proved in the manner provided in Section 1406.

          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 manner which the Trustee deems sufficient.

          The ownership, principal amount and serial number of Registered
Securities shall be proved by the Security Register.

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

                                       11
        
21          
          Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future
Holder of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Company in reliance thereon, whether or not notation of such action is made
upon such Security.

          The Company may, in the circumstances permitted by the Trust
Indenture Act, set any day as the record date for the purpose of determining
the Holders of Outstanding Registered Securities of any series entitled to
give or take any request, demand, authorization, direction, notice, consent,
waiver or other action or permitted by this Indenture to be given or taken by
Holders of Securities of such series.  With regard to any record date set
pursuant to this paragraph, the Holders of Outstanding Registered Securities
of the relevant series on such record date (or their duly appointed agents),
and only such Persons, shall be entitled to give or take the relevant action,
whether or not such Holders remain Holders after such record date.  With
regard to any action that may be given or taken hereunder only by Holders of a
requisite principal amount of Outstanding Securities of any series (or their
duly appointed agents) and for which a record date is set pursuant to this
paragraph, the Company may, at its option, set an expiration date after which
no such action purported to be given or taken by any Holder shall be effective
hereunder unless given or taken on or prior to such expiration date by Holders
of the requisite principal amount of Outstanding Registered Securities of such
series on such record date (or their duly appointed agents).  On or prior to
any expiration date set pursuant to this paragraph, the Company may, on one or
more occasions at its option, extend such date to any later date.  Nothing in
this paragraph shall prevent any Holder (or any duly appointed agent thereof)
from giving or taking, after any expiration date, any action identical to, or,
at any time, contrary to or different from, any action given or taken, or
purported to have been given or taken, hereunder by a Holder on or prior to
such date, in which event the Company may set a record date in respect thereof
pursuant to this paragraph.  Notwithstanding the foregoing or the Trust
Indenture Act, the Company shall not set a record date for, and the provisions
of this paragraph shall not apply with respect to, any action to be given or
taken by Holders pursuant to Sections 501, 502 or 512.  

          Without limiting the foregoing, a Holder entitled hereunder to give
or take any action hereunder with regard to any particular Security may do so
with regard to all or any part of the principal amount of such Security or by

                                       12
22
one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any different part of such principal amount.

Section 105.   NOTICES, ETC., TO TRUSTEE AND COMPANY.

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

          (1)  the Trustee by any Holder or by the Company shall be sufficient
     for every purpose hereunder if made, given, furnished or filed in writing
     to or with the Trustee at its Corporate Trust Office or sent by
     telefacsimile to the Trustee at (312) 461-3525 or at any other number
     previously furnished in writing to the Company by the Trustee, or

          (2)  the Company by the Trustee or by any Holder shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided)
     if in writing and mailed, first-class postage prepaid, to the Company
     addressed to it to the attention of its Treasurer at the address of its
     principal office specified in the first paragraph of this instrument or
     at any other address previously furnished in writing to the Trustee by
     the Company or if sent to the Company by telefacsimile addressed to it to
     the attention of its Treasurer at (702) 876-7037.

Section 106. NOTICE TO HOLDERS; WAIVER.

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

          (1)  such notice shall be sufficiently given to Holders of
     Registered Securities if in writing and mailed, first-class postage
     prepaid, to each Holder of a Registered Security affected by such event,
     at his address as it appears in the Security Register, not later than the
     latest date, and not earlier than the earliest date, prescribed for the
     giving of such Notice; and

          (2)  such notice shall be sufficiently given to Holders of Bearer
     Securities, if any, if published in an Authorized Newspaper in The City
     of New York and, if such Securities are then listed on any stock exchange
     outside the United States, in an Authorized Newspaper in such city as the
     Company shall advise the Trustee that such stock exchange so requires, on
     a Business Day at least twice, the first such publication to be not
     earlier than the earliest date and not later than the latest date
     prescribed for the giving of such notice.
     
                                       13
        
23
          In any case where notice to Holders of Registered Securities is
given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder of a Registered Security shall
affect the sufficiency of such notice with respect to other Holders of
Registered Securities or the sufficiency of any notice to Holders of Bearer
Securities given as provided herein.  Any notice which is mailed in the manner
herein provided shall be conclusively presumed to have been duly given or
provided.  In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder.

          In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of 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 Holders of Bearer Securities as provided above, nor any defect
in any notice so published, shall affect the sufficiency of any notice mailed 
to Holders of Registered Securities as provided above.

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

Section 107.   CONFLICT WITH TRUST INDENTURE ACT.

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

Section 108.   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 109.   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 110.   SEPARABILITY CLAUSE.

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

Section 111.   BENEFITS OF INDENTURE.

          Nothing in this Indenture, the Securities or any Coupon, express or
implied, shall give to any Person (including any Paying Agent or
Authenticating Agent appointed pursuant to Section 614), other than the
parties hereto and holders of Senior Indebtedness and their successors
hereunder and the Holders of Securities or Coupons, any benefit or any legal
or equitable right, remedy or claim under this Indenture.

Section 112.   GOVERNING LAW.

          This Indenture, the Securities and any Coupons shall be governed by
and construed in accordance with the law of the State of New York, but without
regard to principles of conflicts of laws.

Section 113.   LEGAL HOLIDAYS.

          In any case where any Interest Payment Date, Redemption Date,
Repurchase Date or Stated Maturity of any Security shall not  be a Business
Day at any Place of Payment, then (notwithstanding any other provision of this
Indenture, any Security or any Coupon other than a provision of the Security
or Coupon which specifically states that such provision shall apply in lieu of
this Section) payment of interest 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, Repurchase
Date, or at the Stated Maturity, provided that no interest shall accrue for
the period from and after such Interest Payment Date, Redemption Date,
Repurchase Date or Stated Maturity, as the case may be.

established by or pursuant to a Board Resolution or in one or more indentures
supplemental hereto, shall have such appropriate insertions, omissions,

endorsements placed thereon as may, consistent herewith, be determined by the

appropriate record of such action shall be certified by the Secretary or an
Assistant Secretary of the Company and delivered to the Trustee at or prior to

authentication and delivery of such Securities.  If all of the Securities of
any series and Coupons established by action taken pursuant to a Board
Resolution are not to be issued at one time, it shall not be necessary to
deliver a record of such action at the time of issuance of each Security of
such series, but an appropriate record of such action shall be delivered at or
before the time of issuance of the first Security of such series.

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

     Securities and, in such case, the Depositary or Depositaries for such
     Global Security or Global Securities and any circumstances other than
     those set forth in Section 305 in which any such Global Security may be

29
          (17)  if such Securities are to be issuable other than solely as
     Registered Securities (whether as Bearer Securities or alternatively as
     Bearer Securities or Registered Securities), and if such Securities are
     to be issued as Bearer Securities, whether the Bearer Securities are to

     authentication);

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

          (19)  the identity of the Trustee for the Securities of the series,
     and the identity of each Paying Agent and Securities Registrar for the
     Securities of the series;

          (20)  the subordination terms of the Securities of the series;

          All Securities of any one series and all Coupons, if any,
appertaining to Bearer Securities of such series shall be substantially
identical except as to denomination and except as may otherwise be provided in
or pursuant to the Board Resolution referred to above and (subject to
Section 303) set forth, or determined in the manner provided, in the Officers'
Certificate referred to above or in any such indenture supplemental hereto.

          If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
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 series.

                                       20
30
Section 302.   DENOMINATIONS.

          In the absence of any specified denomination with respect to the
Securities of any series, the Securities of such series shall be issuable in
denominations of $1,000 and any integral multiple thereof.

Section 303.   EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

          The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Vice Chairman of the Board, its President or one of
its Vice Presidents, under its corporate seal reproduced thereon attested by
its Secretary or one of its Assistant Secretaries.  Coupons shall be executed
on behalf of the Company by its Treasurer or any Assistant Treasurer.  The
signature of any of these officers on the Securities or any Coupon may be
manual or facsimile.

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

          At any time and from time to time after the execution and delivery
of this Indenture, the Company may deliver Securities of any series, together
with Coupons 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.  The Trustee shall be
entitled to receive and (subject to Section 601) shall be fully protected in
relying upon an Opinion of Counsel stating that such Securities and Coupons,
if any, when authenticated and delivered by the Trustee and issued by
the Company in the manner and subject to any conditions specified in such
Opinion of Counsel, will constitute the legally valid and binding obligations
of the Company enforceable against the Company in accordance with their terms,
except as may be limited by bankruptcy, insolvency, reorganization, moratorium
or similar laws relating to or affecting creditors' rights generally
(including, without limitation, fraudulent conveyance laws) and by general
principles of equity, including, without limitation, concepts of materiality,
reasonableness, good faith and fair dealing and the possible unavailability of
specific performance or injunctive relief regardless of whether considered in
a proceeding in equity or at law.

                                       21
        
31
          If the form or terms of the Securities of the series and any Coupons
appertaining thereto have been established in or pursuant to one or more Board
Resolutions as permitted by Sections 201 and 301, in authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities and any Coupons appertaining thereto, the
Trustee shall be entitled to receive, and (subject to Section 601) shall be
fully protected in relying upon, an Opinion of Counsel stating,

          (1)  if the form of such Securities and Coupons, if any, have been
     established by or pursuant to Board Resolution as permitted by
     Section 201, that such form or forms have been established in conformity
     with the provisions of this Indenture; and

          (2)  if the terms of such Securities and Coupons, if any, have been
     established by or pursuant to Board Resolution as permitted by
     Section 301, that such terms have been established in conformity with the
     provisions of this Indenture.

          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 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 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at
one time, it shall not be necessary to deliver the Officers' Certificate
otherwise required pursuant to Section 301 or the Company Order and Opinion of
Counsel otherwise required pursuant to such preceding paragraph at or prior to
the time of authentication of each Security of such series if such documents
are delivered at or prior to the authentication upon original issuance of the
first Security of such series to be issued.

          Each Registered Security shall be dated the date of its
authentication.  Each Bearer Security shall be dated as of the date specified
pursuant to Section 301.

          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 a certificate of authentication substantially in the form
provided for herein executed by the Trustee by manual signature, and such 
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.  Except as permitted by Section 306 or 307, the Trustee shall not

                                       22
32
authenticate and deliver any Bearer Security unless all Coupons appertaining
thereto then matured have been detached and cancelled.  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 309, 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 304.   TEMPORARY SECURITIES.

          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 or pursuant to this
Indenture, in bearer form with one or more Coupons or without Coupons and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

          Every temporary Security shall be executed by the Company and
authenticated by the Trustee and registered by the Security Registrar, upon
the same conditions, and with like effect, as a definitive Security.

          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 unmatured
Coupons appertaining thereto), the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor one or more definitive
Securities of the same series, of any authorized denominations and of a like
aggregate principal amount and tenor; PROVIDED, HOWEVER, that no definitive
Bearer Security, except as provided in or pursuant to this Indenture, shall be
delivered in exchange for a temporary Registered Security; and PROVIDED
FURTHER that a definitive Bearer Security shall be delivered in exchange for a
temporary Bearer Security only in compliance with the conditions set forth in
or pursuant to this Indenture.  Until so exchanged the temporary Securities of
any series shall in all respects be entitled to the same benefits under this

                                       23
33
Indenture as definitive Securities of such series and tenor.

Section 305.   REGISTRATION, REGISTRATION OF
               TRANSFER AND EXCHANGE.       

          The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office and in any
other office or agency of the Company in a Place of Payment being herein
sometimes collectively referred to as the "Security Register") in which,
subject to such reasonable regulations as it may prescribe, the Company shall
provide for the registration of Securities and of transfers of Registered
Securities.  The Trustee is hereby appointed "Security Registrar" for the
purpose of registering Registered Securities and transfers of Registered
Securities as herein provided.

          Upon surrender for registration of transfer of any Registered
Security of any series at the office or agency 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 and tenor.

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

          If provided in or pursuant to this Indenture, with respect to
Securities of any series, at the option of the Holder, Bearer Securities of
such series may be exchanged for Registered Securities of such series
containing identical terms, denominated as authorized in or pursuant to this
Indenture and in the same aggregate principal amount, upon surrender of the
Bearer Securities to be exchanged at any office or agency in a Place
of Payment for such series, with all unmatured Coupons and all matured Coupons
in default thereto appertaining.  If the Holder of a Bearer Security is unable
to produce any such unmatured Coupon or Coupons or matured Coupon or Coupons
in default, such exchange may be effected if the Bearer Securities are
accompanied by payment in funds acceptable to the Company and the Trustee in
an amount equal to the face amount of such missing Coupon or Coupons, or the
surrender of such missing Coupon or Coupons may be waived by the Company and
the Trustee if there is furnished to them such security or indemnity as they
may require to save each of them and any Paying Agent harmless.  If

                                       24
34
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have
been made, such Holder shall be entitled to receive the amount of such
payment; PROVIDED, HOWEVER, that, except as otherwise provided in Section
1002, interest represented by Coupons shall be payable only upon presentation
and surrender of those Coupons at an office or agency in a Place of Payment
for such series located outside the United States.  Notwithstanding the
foregoing, in case a Bearer Security is surrendered at any such office or
agency in a Place of Payment for such series in exchange for a Registered
Security of such series and like tenor after the close of business at such
office or agency on (i) any Regular Record Date, or (ii) any Special Record
Date and before the opening of business at such office or agency on the
related date for payment of Defaulted Interest, such Bearer Security shall be
surrendered without the Coupon relating to such Interest Payment Date or
proposed date of payment, as the case may be (or, if such Coupon is so
surrendered with such Bearer Security, such Coupon shall be returned to the
Person so surrendering the Bearer Security), and interest or Defaulted
Interest, as the case may be, shall not be payable on such Interest Payment
Date or proposed date for payment, as the case may be, in respect of the
Registered Security issued in exchange for such Bearer Security, but shall be
payable only to the Holder of such Coupon when due in accordance with the
provisions of this Indenture.

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

          Whenever any Securities are surrendered for exchange as contemplated
by the immediately preceding two paragraphs, the Company shall execute, and
the Trustee shall authenticate and deliver, the Securities which the Holder
making the exchange is entitled to receive.

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

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

                                       25
        
35
          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 304, 906 or 1107 not involving any
transfer.

          The Company shall not be required (1) to issue, register the
transfer of or exchange Securities of any series during a period beginning at
the opening of business 15 days before the day of the mailing of a notice of
redemption of Securities of that series selected for redemption under
Section 1103 and ending at the close of business on the day of such mailing,
or (2) to register the transfer or exchange of any Registered Security so
selected for redemption in whole or in part, except the unredeemed portion of
any Security being redeemed in part or (3) to exchange any Bearer Security so
selected for redemption except, to the extent provided with respect to such
Bearer Security, that such Bearer Security may be exchanged for a Registered
Security of like tenor and the same series, provided that such Registered
Security shall be immediately surrendered for redemption with written
instructions for payment consistent with the provisions of this Indenture.

          Notwithstanding any other provision in this Indenture, no Global
Security may be transferred to, or registered or exchanged for Securities
registered in the name of, any Person other than the Depositary for such
Global Security or any nominee thereof, and no such transfer may be
registered, unless (1) such Depositary (A) notifies the Company that it is
unwilling or unable to continue as Depositary for such Global Security or (B)
ceases to be a clearing agency registered under the Exchange Act, (2) the
Company executes and delivers to the Trustee a Company Order that such Global
Security shall be so transferable, registrable and exchangeable, and such
transfers shall be registrable, (3) there shall have occurred and be
continuing an Event of Default with respect to the Securities evidenced by
such Global Security or (4) there shall exist such other circumstances, if
any, as have been specified for this purpose as contemplated by Section 301. 
Notwithstanding any other provision in this Indenture, a Global Security to
which the restriction set forth in the preceding sentence shall have ceased to
apply may be transferred only to, and may be registered and exchanged for
Securities registered only in the name or names of, such Person or Persons as
the Depositary for such Global Security shall have directed and no transfer
thereof other than such a transfer may be registered.

          Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Security to which the

                                       26
36
restriction set forth in the first sentence of the preceding paragraph shall
apply, whether pursuant to this Section, Section 304, 306, 906 or 1107 or
otherwise, shall be authenticated, registered and delivered in the form of,
and shall be, a Global Security.

Section 306.   MUTILATED, DESTROYED,
               LOST AND STOLEN SECURITIES.

          If any mutilated Security or a Security with a mutilated Coupon
appertaining to it is surrendered to the Trustee, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a new
Security of the same series and of like tenor and principal amount and bearing
a number not contemporaneously outstanding, with Coupons appertaining thereto
corresponding to the Coupons, if any, appertaining to the surrendered
Security.

          If there shall be delivered to the Company and 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 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 of like tenor and
principal amount and bearing a number not contemporaneously outstanding, with
Coupons corresponding to the Coupons, if any, appertaining to such destroyed,
lost or stolen Security or to the Security to which such destroyed, lost or
stolen Coupon appertains.

          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, pay such Security or
Coupon.

          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 any Coupons appertaining
thereto, issued pursuant to this Section in lieu of any mutilated, 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 mutilated,
destroyed, lost or stolen Security or Coupon shall be at any time enforceable

                                       27
37
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 any
Coupons 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.

Section 307.   PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

          Except as otherwise provided as contemplated by Section 301 with
respect to any series of Securities, interest on any Registered Security which
is payable, and is punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the Person in whose name that Registered Security
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest.  Except as otherwise provided as
contemplated by Section 301 with respect to any series of Securities, in case
a Bearer Security is surrendered in exchange for a Registered Security after
the close of business (at an office or agency at a Place of Payment for such
Security) on any Regular Record Date therefor and before the opening of
business (at such office or agency) on the next succeeding Interest Payment
Date therefor, such Bearer Security shall be surrendered without the Coupon
relating to such Interest Payment Date and interest shall not be payable on
such Interest Payment Date in respect of the Registered Security issued in
exchange for such Bearer Security, but shall be payable only to the Holder of
such Coupon when due in accordance with the provisions of this Indenture.

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

          (1)  The Company may elect to make payment of any Defaulted Interest
     to the Persons in whose names the 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, and at the same time the Company
     
                                       28
   
38
     shall deposit with the Trustee an amount of money equal to the aggregate
     amount proposed to be paid in respect of such Defaulted Interest or shall
     make arrangements satisfactory to the Trustee for such deposit prior to
     the date of the proposed payment, such money when deposited to be held in
     trust for the benefit of the Persons entitled to such Defaulted Interest
     as in this Clause provided.  Thereupon the Trustee shall fix a Special
     Record Date for the payment of such Defaulted Interest which shall be not
     more than 15 days and not less than 10 days prior to the date of the
     proposed payment and not less than 10 days after the receipt by the
     Trustee of the notice of the proposed payment.  The Trustee shall
     promptly notify the Company of such Special Record Date and, in the name
     and at the expense of the Company, shall cause notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor
     to be mailed, first-class postage prepaid, to each Holder of 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. 
     Notice of the proposed payment of such Defaulted Interest and the Special
     Record Date therefor having been so mailed, such Defaulted Interest shall
     be paid to the Persons in whose names the 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
     is surrendered at the office or agency at a Place of Payment for such
     Security in exchange for a Registered Security after the close of
     business at such office or agency on any Special Record Date and before
     the opening of business at such office or agency on the related proposed
     date for payment of Defaulted Interest, such Bearer Security shall be
     surrendered without the Coupon relating to such proposed date of payment
     and Defaulted Interest shall not be payable on such proposed date of
     payment in respect of the Registered Security issued in exchange for such
     Bearer Security, but shall be payable only to the Holder of such Coupon
     when due in accordance with the provisions of this Indenture.

          (2)  The Company may make payment of any Defaulted Interest on the
     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 is 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, each Security
delivered under this Indenture upon registration of transfer of or in

                                       29
39
     exchange for or in lieu of any other Security shall carry the rights to
     interest accrued and unpaid, and to accrue, which were carried by such
     other Security.

Section 308.   PERSONS DEEMED OWNERS.

          Prior to due presentment of a Registered Security for registration
of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name such Registered Security is
registered as the owner of such Security for the purpose of receiving payment
of principal of and any premium and (except as contemplated by Section 301(3)
and subject to Section 307) any interest on such Security and for all other
purposes whatsoever, whether or not such 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.

          The Company, the Trustee and any agent of the Company or the Trustee
may treat the bearer of any Bearer Security or the bearer of any Coupon as the
absolute owner of such Security or Coupon for the purpose of receiving payment
thereof or on account thereof and for all other purposes whatsoever, whether
or not any payment with respect to such Security or Coupon shall be overdue,
and neither the Company, nor the Trustee or 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 Global Security or for maintaining, supervising or reviewing
any records relating to such beneficial ownership interests.

          In the event the Securities are issued in book-entry form with the
Depositary, the Trustee may deal with the Depositary as the authorized
representative of the Holders and the Depositary may be treated by the Trustee
and its agents, employees, officers and directors as the Holder of the

                                       31
             
41
               (B)  all such Securities and, in the case of (i) and (ii)
          below, any Coupons appertaining thereto not theretofore delivered to
          the Trustee for cancellation

                    (i)  have become due and payable, or

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

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

          and the Company, in the case of (i), (ii) or (iii) above, has
          deposited or caused to be deposited with the Trustee as trust funds
          in trust for the purpose an amount sufficient to pay and discharge
          the entire indebtedness on such Securities and any Coupons
          appertaining thereto not theretofore delivered to the Trustee for
          cancellation, for principal and any premium and interest 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;

          (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 have been complied with.

          Notwithstanding the satisfaction and discharge of this Indenture,
the obligations of the Company to the Trustee under Section 607, the
obligations of the Trustee to any Authenticating Agent under Section 614 and,
if money shall have been deposited with the Trustee pursuant to subclause (B)

and the last paragraph of Section 1003 shall survive.

Section 402.   APPLICATION OF TRUST MONEY.

          Subject to provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in
trust and applied by it, in accordance with the provisions of the Securities
and this Indenture, to the payment, either directly or through any Paying
Agent (including the Company acting as its own Paying Agent) as the Trustee

                                       32

Section 501.   EVENTS OF DEFAULT.

          "Event of Default", wherever used herein with respect to Securities
of any series, means any one of the following events (whatever the reason for
such Event of Default and whether it shall be occasioned by the provisions of
Article Fourteen or 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 any Security of
     that series when it becomes due and payable, and continuance of such
     default for a period of 30 days; provided, however, that a valid
     extension of the interest payment provided by the Company for any
     Security in accordance with the terms of any indenture supplement hereto
     shall not constitute a default in the payment of interest and, provided
     further, that if Securities are issued to the Trust or a trustee of the
     Trust in connection with the issuance of Trust Securities by the Trust,
     such 30 day period will be replaced by a 10 day period; or

          (2)  default in the payment of the principal of (or premium, if any,
     on) any Security of that series at its Maturity; provided, however, that
     a valid extension of the maturity of such Securities in accordance with
     the terms of any indenture supplemental hereto shall not constitute a
     default in the payment of principal or premium, if any; or

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

          (4)  default in the performance, or breach, of any covenant or
     warranty of the Company in this Indenture (other than a covenant or
     warranty a default in whose performance or whose breach is elsewhere in
     this Section specifically dealt with or which has expressly been included
     in this Indenture solely for the benefit of series of Securities other
     than that series), and continuance of such default or breach for a period
     of 60 days after there has been given, by registered or certified mail,
     to the Company by the Trustee or to the Company and the
     
                                       33

     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)  a default under any bond, debenture, note or other evidence of
     indebtedness for money borrowed by the Company (including a default with
     respect to Securities of any series other than that series) in an
     individual principal amount outstanding of at least $15,000,000 or under
     any mortgage, indenture or instrument under which there may be issued or
     by which there may be secured or evidenced any indebtedness for money
     borrowed by the Company in an individual principal amount outstanding of
     at least $5,000,000, whether such indebtedness now exists or shall
     hereafter be created, which default shall have resulted in such
     indebtedness becoming or being declared due and payable prior to the date
     on which it would otherwise have become due and payable, without such
     acceleration having been rescinded or annulled, within a period of
     10 Business Days after there shall have 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 and requiring the Company to cause such acceleration to be
     rescinded or annulled and stating that such notice is a "Notice of
     Default" hereunder; PROVIDED, HOWEVER, that, subject to the provisions of
     Sections 601 and 602, the Trustee shall not be deemed to have knowledge
     of such default unless either (A) a Responsible Officer of the Trustee
     shall have actual knowledge of such default or (B) the Trustee shall have
     received written notice thereof from the Company, from any Holder, from
     the holder of any such indebtedness or from the trustee under any such
     mortgage, indenture or other instrument; or

         (6)  the entry by a court having jurisdiction in the premises of
     (A) a decree or order for relief in respect of the Company in an
     involuntary case or proceeding under any applicable Federal or State
     bankruptcy, insolvency, reorganization or other similar law or (B) a
     decree or order adjudging the Company a bankrupt or insolvent, or
     approving as properly filed a petition seeking reorganization,
     arrangement, adjustment or composition of or in respect of the Company
     under any applicable Federal or State law, or appointing a custodian,
     receiver, liquidator, assignee, trustee, sequestrator or other similar
     official of the Company or of any substantial part of its property, or
     ordering the winding up or liquidation of its affairs, and the continuance
     
                                       34
   
44
     of any such decree or order for relief or any such other decree or order 
     unstayed and in effect for a period of 60 consecutive days; or

         (7)  the commencement by the Company of a voluntary case or
     proceeding under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law or of any other case or proceeding to
     be adjudicated a bankrupt or insolvent, or the consent by it to the entry
     of a decree or order for relief in respect of the Company in an
     involuntary case or proceeding under any applicable Federal or State
     bankruptcy, insolvency, reorganization or other similar law or to the
     commencement of any bankruptcy or insolvency case or proceeding against
     it, or the filing by it of a petition or answer or consent seeking
     reorganization or relief under any applicable Federal or State law, or
     the consent by it to the filing of such petition or to the appointment of
     or taking possession by a custodian, receiver, liquidator, assignee,
     trustee, sequestrator or other similar official of the Company or of any
     substantial part of its property, or the making by it of an assignment
     for the benefit of creditors, or the admission by it in writing of its
     inability to pay its debts generally as they become due, or the taking of
     corporate action by the Company in furtherance of any such action;

          (8)  in the event Securities are issued and sold to a Trust or a
     trustee of the Trust in connection with the issuance of Trust Securities
     by the Trust, the Trust shall have voluntarily or involuntarily
     dissolved, wound up its business or otherwise terminated its existence
     except in connection with (i) the distribution of Securities to holders
     of Trust Securities in liquidation or redemption of their interests in
     the Trust, (ii) the redemption of all of the outstanding Trust Securities
     of the Trust, or (iii) certain mergers, consolidations or amalgamations,
     each as permitted by the Declaration of the Trust; or

          (9)  any other Event of Default provided with respect to Securities
     of that series; PROVIDED, HOWEVER, that a valid extension of the interest
     payment provided by the Company for the Subordinated Debt Securities
     shall not constitute a default in the payment of interest for this
     purpose.

          Upon receipt by the Trustee of any Notice of Default pursuant to
this Section 501 with respect to Securities of any series, a record date shall
automatically and without any other action by any Person be set for the
purpose of determining the Holders of Outstanding Securities of such series
entitled to join in such Notice of Default, which record date shall be the
close of business on the day the Trustee receives such Notice of Default.

                                       35
45
The Holders of Outstanding Securities of such series on such record date (or 
their duly appointed agents), and only such Persons, shall be entitled
to join in such Notice of Default, whether or not such Holders remain Holders
after such record date; provided that, unless such Notice of Default shall have
become effective by virtue of Holders of the requisite principal amount of
Outstanding Securities of such series on such record date (or their duly
appointed agents) having joined therein on or prior to the 90th day after such
record date, such Notice of Default shall automatically and without any action
by any Person be canceled and of no further effect.  Nothing in this paragraph
shall prevent a Holder (or a duly appointed agent thereof) from giving, before
or after the expiration of such 90-day period, a Notice of Default contrary to
or different from, or, after the expiration of such period, identical to, a
Notice of Default that has been canceled pursuant to the proviso to the
preceding sentence, in which event a new record date in respect thereof shall
be set pursuant to this paragraph.

Section 502.   ACCELERATION OF MATURITY;
               RESCISSION AND ANNULMENT.

          If an Event of Default with respect to Securities of any series at
the time Outstanding occurs and is continuing, then 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 amount (or, if
any of the Securities of that series are Original Issue Discount Securities,
such portion of the principal amount of such Securities as may be specified in
the terms thereof) of all of 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 Holders), and upon any such declaration such principal amount (or
specified amount) 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

               (A)  all overdue interest on all Securities of that series and
          any Coupons appertaining thereto,

               (B)  the principal of (and premium, if any, on) any Securities
          of that series which have become due otherwise than by such
          
                                       36
        
46
          declaration of acceleration and any interest thereon at the rate or
          rates prescribed therefor in such Securities,

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

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

     and

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

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

          Upon receipt by the Trustee of any declaration of acceleration, or
any rescission and annulment of any such declaration, pursuant to this Section
502 with respect to Securities of any series, a record date shall
automatically and without any other action by any Person be set for the
purpose of determining the Holders of Outstanding Securities of such series
entitled to join in such declaration, or rescission and annulment, as the case
may be, which record date shall be the close of business on the day the
Trustee receives such declaration, or rescission and annulment, as the case
may be.  The Holders of Outstanding Securities of such series on such record
date (or their duly appointed agents), and only such Persons, shall be
entitled to join in such declaration, or rescission and annulment, as the case
may be, whether or not such Holders remain Holders after such record date;
provided that, unless such declaration, or rescission and annulment, as the
case may be, shall have become effective by virtue of Holders of the requisite
principal amount of Outstanding Securities of such series on such record date
(or their duly appointed agents) having joined therein on or prior to the 90th
day after such record date, such declaration, or rescission and annulment, as
the case may be, shall automatically and without any action by any Person be
canceled and of no further effect.  Nothing in this paragraph shall prevent a
Holder (or a duly appointed agent thereof) from giving, before or after the
expiration of such 90-day period, a declaration of acceleration, or a
rescission and annulment of any such declaration, contrary to or different
from, or, after the expiration of such period,identical to, a declaration, or

                                       37
47
rescission and annulment, as the case may be, that has been canceled pursuant
to the proviso to the preceding sentence, in which event a new record date in
respect thereof shall be set pursuant to this paragraph.

Section 503.   COLLECTION OF INDEBTEDNESS AND
               SUITS FOR ENFORCEMENT BY TRUSTEE.

          The Company covenants that if

          (1)  default is made in the payment of any interest on any Security
     or any Coupon appertaining thereto when such interest becomes due and
     payable and such default continues for a period of 30 days or 10 days in
     the case of Securities issued to a Trust or a trustee of the Trust, or 

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of
the Holders of such Securities and any Coupons appertaining thereto, the whole
amount then due and payable on such Securities and any Coupons appertaining
thereto for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such 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 an Event of Default with respect to Securities of any series
occurs and is continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Securities of such
series and any Coupons appertaining thereto by such appropriate judicial
proceedings as the Trustee shall deem most effectual to protect and enforce
any such rights, whether for the specific enforcement of any covenant or
agreement in this Indenture or in aid of the exercise of any power granted
herein, or to enforce any other proper remedy.

Section 504.   TRUSTEE MAY FILE PROOFS OF CLAIM.

          In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities or any Coupons appertaining thereto), its
property or its creditors, the Trustee shall be entitled and empowered, by
intervention in such proceeding or otherwise, to take any and all actions
authorized under the Trust Indenture Act in order to have claims of the

                                       38
48
Holders and the Trustee allowed in any such proceeding.  In particular, the
Trustee shall be authorized to collect and receive any moneys or other
property payable or deliverable on any such claims and to distribute the same;
and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders,
to pay to the Trustee any amount due it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel,
and any other amounts due the Trustee under Section 607.

          No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting
the Securities or any Coupon or the rights of any Holder thereof or to
authorize the Trustee to vote in respect of the claim of any Holder in any
such proceeding; PROVIDED, HOWEVER, that the Trustee may, on behalf of the
Holders, vote for the election of a trustee in bankruptcy or similar official
and be a member of a creditors' or other similar committee.

Section 505.   TRUSTEE MAY ENFORCE CLAIMS 
               WITHOUT POSSESSION OF SECURITIES.

          All rights of action and claims under this Indenture or 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 or Coupons in respect of which such judgment has been recovered.

Section 506.   APPLICATION OF MONEY COLLECTED.

          Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or any
premium or interest, 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 under
     Section 607; and
     
                                       39
        
49
          SECOND:  To the payment of the amounts then due and unpaid for
     principal of and any premium and interest on the Securities and any
     Coupon in respect of which or for the benefit of which such money has
     been collected, ratably, without preference or priority of any kind,
     according to the amounts due and payable on such Securities and Coupons
     for principal and any premium and interest, respectively.

Section 507.      LIMITATION ON SUITS.

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

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

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

         (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 of such Holders.

Section 508.   UNCONDITIONAL RIGHT OF HOLDERS TO
               RECEIVE PRINCIPAL, PREMIUM AND INTEREST.

          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 any premium and
(except as contemplated by Section 301(3) and subject to Section 307) interest
on such Security or payment of such Coupon, as the case may be, on the
respective Stated Maturities 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 509.   RESTORATION OF RIGHTS AND REMEDIES.

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

Section 510.   RIGHTS AND REMEDIES CUMULATIVE.

          Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities or Coupons in the
last paragraph of Section 306, no right or remedy herein conferred upon or
reserved to the Trustee or to the Holders is intended to be exclusive of any
other right or remedy, and every right and remedy shall, to the extent
permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise.  The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any
other appropriate right or remedy.

Section 511.   DELAY OR OMISSION NOT WAIVER.

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

                                       41
 51                                       
Section 512.   CONTROL BY HOLDERS.

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

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

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

          Upon receipt by the Trustee of any such direction with respect to
Securities of any series, a record date shall automatically and without any
other action by any Person be set for determining the Holders of Outstanding
Securities of such series entitled to join in such direction, which record
date shall be the close of business on the day the Trustee receives such
direction.  The Holders of Outstanding Securities of such series on such
record date (or their duly appointed agents), and only such Persons, shall be
entitled to join in such direction, whether or not such Holders remain Holders
after such record date; provided that, unless such direction shall have become
effective by virtue of Holders of the requisite principal amount of
Outstanding Securities of such series on such record date (or their duly
appointed agents having joined therein on or prior to the 90th day after such
record date, such direction shall automatically and without any action by any
Person be canceled and of no further effect.  Nothing in this paragraph shall
prevent a Holder (or a duly appointed agent thereof) from giving, before or
after the expiration of such 90-day period, a direction contrary to or
different from, or, after the expiration of such period, identical to, a
direction that has been canceled pursuant to the proviso to the preceding
sentence, in which event a new record date in respect thereof shall be set
pursuant to this paragraph.

Section 513.   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 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 any premium or interest
     on any Security of such series or any Coupons appertaining thereto, or
          
                                       42
          
 52                                       
          (2)  in respect of a covenant or provision hereof which under
     Article Nine cannot be modified or amended without the consent of the
     Holder of each Outstanding Security of such series affected.

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

Section 514.   UNDERTAKING FOR COSTS.

          In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered
or omitted by it as Trustee, a court may require any party litigant in such
suit to file an undertaking to pay the costs of such suit, and may assess
costs against any such party litigant, in the manner and to the extent
provided in the Trust Indenture Act; provided that neither this Section nor
the Trust Indenture Act shall be deemed to authorize any court to require such
an undertaking or to make such an assessment in any suit instituted by the
Company.

Section 515.   WAIVER OF USURY, STAY OR EXTENSION LAWS.

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


                                 ARTICLE SIX

                                 THE TRUSTEE

Section 601.   CERTAIN DUTIES AND RESPONSIBILITIES.

          The duties, responsibilities, rights, immunities and protection of
the Trustee shall be as provided by the Trust Indenture Act.  Prior to any
Event of Default the Trustee shall not be liable except for the performance of
such duties as are specifically set out herein and in the Trust Indenture Act. 
Notwithstanding the foregoing, no provision of this Indenture shall require

                                       43
 53                                       
the Trustee 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.  Whether or not therein
expressly so provided, every provision of this Indenture relating to the
conduct or affecting the liability of or affording protection to the Trustee
shall be subject to the provisions of this Section.

Section 602.   NOTICE OF DEFAULTS.

          The Trustee shall give notice of any default known to a Responsible
Officer of the Trustee with respect to the Securities of any series when, as
and to the extent provided by the Trust Indenture Act and in the manner
provided by Section 106 hereof; PROVIDED, HOWEVER, that in the case of any
default of the character specified in Section 501(4) with respect to
Securities of such series, no such notice to Holders shall be given until at
least 30 days after the default is known to a Responsible Officer of the
Trustee.  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 Securities of such series.

Section 603.   CERTAIN RIGHTS OF TRUSTEE.

          Subject to the provisions of Section 601:

          (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, other evidence of indebtedness or other paper or
     document believed by it to be genuine and to have been signed or
     presented by the proper party or parties;

     resolution of the Board of Directors shall 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;
     
                                       44
          
 54                                       
          (4)  the Trustee may consult with counsel and the written 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 pursuant to this Indenture, unless such
     Holders shall have offered to the Trustee reasonable security or
     indemnity against the costs, expenses and liabilities (including legal
     fees and expenses) which might be incurred by it in compliance with such
     request or direction;

          (6)  the Trustee shall not be bound to make any investigation into
     the facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document, but the Trustee, in its discretion, may make such further
     inquiry or investigation into such facts or matters as it may see fit,
     and, if the Trustee shall determine to make such further inquiry or
     investigation, it shall be entitled to examine the books, records and
     premises of the Company, personally or by agent or attorney upon 10
     Business Days advance written notice and during regular business hours;
     and 

          (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.

Section 604.   NOT RESPONSIBLE FOR RECITALS
               OR ISSUANCE OF SECURITIES.  

          The recitals contained herein and in the Securities and Coupons,
except the Trustee's certificates of authentication, shall be taken as the
statements of the Company, and the Trustee or any Authenticating Agent assumes
no responsibility for their correctness.  The Trustee makes no representations
as to the validity or sufficiency of this Indenture or of the Securities
or Coupons.  The Trustee or any Authenticating Agent shall not be accountable
for the use or application by the Company of Securities or the proceeds
thereof.

                                       45
 55                                       
Section 605.   MAY HOLD SECURITIES OR COUPONS.

          The Trustee, any Authenticating Agent, any Paying Agent, any
Security Registrar or any other agent of the Company, in its individual or any
other capacity, may become the owner or pledgee of Securities or Coupons and,
subject to Sections 608 and 613, may otherwise deal with the Company with the
same rights it would have if it were not Trustee, Authenticating Agent, Paying
Agent, Security Registrar or such other agent. 

Section 606.   MONEY HELD IN TRUST.

          Money held by the Trustee, or by any Paying Agent (other than the
Company if the Company shall act as Paying Agent), 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 607.   COMPENSATION AND REIMBURSEMENT.

          The Company agrees

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

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

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

          As security for the performance of the obligations of the Company
under this Section, the Trustee shall have a claim prior to the Securities
upon all property and funds held or collected by the Trustee as such, except

                                       46
 56                                       
funds held in trust for the payment of principal of (and premium, if any) or
interest on particular Securities or any coupons.

          When the Trustee renders services or incurs expenses after the
occurrence of an Event of Default specified in Sections 501(6) or 501(7)
hereof, the compensation for services and expenses are intended to constitute
expenses of administration under any applicable bankruptcy or insolvency law
or law applicable to creditors' rights to the extent permitted by applicable
law.

Section 608.   DISQUALIFICATION; CONFLICTING INTERESTS.

          If the Trustee has or shall acquire a conflicting interest within
the meaning of the Trust Indenture Act, 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 Trust Indenture Act and this Indenture and
the Company shall take prompt action to have a successor Trustee appointed in
the manner provided herein.

Section 609.   CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

          There shall at all times be one or more Trustees hereunder with
respect to the Securities of each series, at least one of which shall be a
Person that (i) is eligible pursuant to the Trust Indenture Act to act as
such, and (ii) has a combined capital and surplus of at least $50,000,000;
PROVIDED, HOWEVER, that if the Trustee shall be a member of a bank holding
company group, such bank holding company group shall have combined capital and
surplus of at least $50,000,000 and the Trustee shall have a combined capital
and surplus of at least $10,000,000.  If such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Person shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published.  If at any time the Trustee shall cease to be eligible in accor-
dance with the provisions of this Section, it shall resign immediately in the
manner and with the effect hereinafter specified in this Article.

Section 610.   RESIGNATION AND REMOVAL;
               APPOINTMENT OF SUCCESSOR.

          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 611.

                                       47
          
 57                                       
          The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company.  If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

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

          If at any time:

          (1)  the Trustee shall fail to comply with Section 608 after written
     request therefor by the Company or by any Holder who has been a bona fide
     Holder of a Security for at least six months, or

          (2)  the Trustee shall cease to be eligible under Section 609 and
     shall fail to resign after written request therefor by the Company or by
     any such Holder, or

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

then, in any such case, (A) the Company by a Board Resolution may remove the
Trustee with respect to all securities, or (B) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee with respect to
all Securities and the appointment of a successor Trustee or Trustees.

          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 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) and shall
comply with the applicable requirements of Section 611.  If, within one year

                                       48
 58                                       
after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to the Securities of any series
shall be appointed by Act of the Holders of a majority in principal amount of
the Outstanding Securities of such series delivered to the Company and the
retiring Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment in accordance with the applicable requirements
of Section 611, 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 and accepted
appointment in the manner required by Section 611, any Holder who has been a
bona fide Holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

          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 to all Holders of Securities of such series in the manner provided in
Section 106.  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.

          No resignation or removal pursuant to this Section 610 shall be
effective unless and until any and all amounts due to such Trustee pursuant to
Section 607 shall have been paid.  The obligations of the Company provided for
in Section 607 hereof shall survive such resignation or removal.

Section 611.   ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

          In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or
removal of the retiring Trustee shall become effective and such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee, provided,
however, that no Trustee under this Indenture shall be liable for any act or
omission of any successor Trustee; but, on the request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all
the rights, powers and trusts of the retiring Trustee and shall duly assign,

                                       49
 59                                       
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder.

          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 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 pro-
vided 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.

          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) and (b) of this Section, as the case may be.

          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.

                                       50

Section 612.   MERGER, CONVERSION, CONSOLIDATION
               OR SUCCESSION TO BUSINESS.       

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on
the part of any of the parties hereto.  In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may
adopt such authentication and deliver the Securities so authenticated with the
same effect as if such successor Trustee had itself authenticated such
Securities.  In the event any Securities shall not have been authenticated by
such predecessor Trustee, any such successor Trustee may authenticate and
deliver such Securities, 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 613.   PREFERENTIAL COLLECTION  
               OF CLAIMS AGAINST COMPANY.   

          If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities or any Coupons), the Trustee shall
be subject to the provisions of the Trust Indenture Act regarding the
collection of claims against the Company (or any such other obligor).

Section 614.   APPOINTMENT OF AUTHENTICATING AGENT.

          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
original issue and upon exchange, registration of transfer or partial
redemption thereof or pursuant to Section 306, and Securities so authenticated
shall be entitled to the benefits of this Indenture and shall be valid and
obligatory for all purposes as if authenticated by the Trustee hereunder. 
Wherever reference is made in this Indenture to the authentication and
delivery of Securities by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating
Agent.  Each Authenticating Agent shall be acceptable to the Company and shall

                                       51
 61                                       
at all times be a corporation organized and doing business under the laws of
the United States of America, any State thereof or the District of Columbia,
authorized under such laws to act as Authenticating Agent, having a combined
capital and surplus of not less than $50,000,000 and subject to supervision or
examination by Federal or State authority.  If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section, the combined capital and surplus of such Authenticating Agent
shall be deemed to be its combined capital and surplus as set forth in its
most recent report of condition so published.  If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, 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 any
further act on the part of the Trustee or the Authenticating Agent.

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

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

          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 the Trustee's certificate of authentication, an
alternative certificate of authentication in the following form:

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

     provided any such action shall not adversely affect the interests of the
     Holders of Securities of any series or any Coupons appertaining thereto
     in any material respect; or

          (5)  to add to, change or eliminate any of the provisions of this

     Securities of any series (except a series consenting pursuant to Section
     902) in any material respect.

Section 902.   SUPPLEMENTAL INDENTURES
               WITH CONSENT OF HOLDERS.

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

     pursuant to Section 502, or change the coin or currency in which any
     Security or any premium or 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, on or
     after the Redemption Date), or modify the provisions of this Indenture
     with respect to the conversion or exchange of the Securities into
     Securities of another series or into any other debt or equity securities
     in a manner adverse to the Holders, 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

     Indenture or certain defaults hereunder and their consequences) provided
     for in this Indenture, or

          (3)  modify any of the provisions of this Indenture relating to the
     subordination of the Securities in a manner adverse to Holders of
     Securities, or

          (4)  modify any of the provisions of this Section or Section 513,
     except to increase any such percentage or to provide that certain other
     provisions of this Indenture cannot be modified or waived without the

     Trustee" and concomitant changes in this Section, or the deletion of this
     proviso, in accordance with the requirements of Sections 611 and 901(8).

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.

          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.

Section 903.   EXECUTION OF SUPPLEMENTAL INDENTURES.

          In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby

receive, and (subject to Section 601) shall be fully protected in relying
upon, an Opinion of Counsel stating that the execution of such supplemental
indenture is authorized or permitted by this Indenture.  The Trustee may, but
shall not be obligated to, enter into any such supplemental indenture which
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

Section 904.   EFFECT OF SUPPLEMENTAL INDENTURES.

          Upon the execution of any supplemental indenture under this Article,

          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.

                                 ARTICLE TEN

                                  COVENANTS

Section 1001.  PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

          The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any
premium and interest on the Securities of that series in accordance with the
terms of the Securities or any Coupons appertaining thereto and this
Indenture.  Any interest due on any Bearer Security or before the maturity
thereof shall be payable only upon presentation and surrender of the Coupons
appertaining thereto for such interest as they severally mature.

Section 1002.  MAINTENANCE OF OFFICE OR AGENCY.

          The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series (but not Bearer
Securities, except as otherwise provided below, unless such Place of Payment
is located outside the United States) may be presented or surrendered for
payment, where Securities of 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 shall
maintain, subject to any laws or regulations applicable thereto, an office or
agency in a Place of Payment for such series which is located outside the
United States where Securities of such series and any Coupons appertaining
thereto may be presented and surrendered for payment.  The Company will give
prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency.  If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee,

                                       60
 70                                       
except that Bearer Securities of such series and any Coupons appertaining
thereto may be presented and surrendered for payment at the place specified
for the purpose with respect to such Securities as provided in or pursuant to
this Indenture, and the Company hereby appoints the Trustee as its agent to
receive all such presentations, surrenders, notices and demands.

          Except as otherwise provided in or pursuant to this Indenture, no
payment of principal, premium or interest with respect to 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 by transfer to an account
maintained with a bank located in the United States; PROVIDED, HOWEVER, if
amounts owing with respect to any Bearer Securities shall be payable in United
States Dollars, payment of principal of and any premium or interest on any
such Security may be made at the Corporate Trust Office of the Trustee or any
office or agency designated by the Company in the United States, but only if
payment of the full amount of such principal, premium or interest at all
offices outside the United States maintained for such purpose by the Company
in accordance with the Indenture is illegal or effectively precluded by
exchange controls or other similar restrictions.

          The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be
presented or surrendered for any or all such purposes and may from time to
time rescind such designations; PROVIDED, HOWEVER, that no such designation or
rescission shall in any manner relieve the Company of its obligation to
maintain an office or agency in each Place of Payment for Securities of any
series for such purposes.  The Company will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the
location of any such other office or agency.

Section 1003.  MONEY FOR SECURITIES 
               PAYMENTS TO BE HELD IN TRUST.

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

          Whenever the Company shall have one or more Paying Agents for any
series of Securities and any Coupons appertaining thereto, it will, prior to

                                       61
 71                                       
each due date of the principal of or any premium or interest on any Securities
of that series, deposit with a Paying Agent a sum sufficient to pay such
amount, such sum to be held as provided by the Trust Indenture Act, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the
Trustee of its action or failure so to act.

          The Company will cause each Paying Agent for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will (1) comply with
the provisions of the Trust Indenture Act applicable to it as a Paying Agent
and (2) during the continuance of any default by the Company (or any other
obligor upon the Securities of that series) in the making of any payment in
respect of the Securities of that series, and upon the written request of the
Trustee, forthwith pay to the Trustee all sums held in trust by such Paying
Agent for payment in respect of the Securities of that series.

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

          Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal of or any
premium or interest on any Security of any series and remaining unclaimed for
two years after such principal, premium or interest has become due and payable
shall be paid to the Company on Company Request (including interest income
accrued on said funds to which the Company is otherwise entitled), or (if then
held by the Company) shall be discharged from such trust; and the Holder of
such Security or any Coupon appertaining thereto shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; PROVIDED, HOWEVER, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause
to be published once, in an Authorized Newspaper in each Place of Payment for
such series, 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

end of each fiscal year of the Company ending after the date hereof, an
Officers' Certificate, stating whether or not to the best knowledge of the

the Company shall be in default, specifying all such defaults and the nature
and status thereof of which they may have knowledge.

Section 1005.  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
existence, rights (charter and statutory) and franchises; PROVIDED, HOWEVER,
that the Company shall not be required to preserve any such right or franchise
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and that the

improvements thereof, all as in the judgment of the Company may be necessary
so that the business carried on in connection therewith may be properly and
advantageously conducted at all times; PROVIDED, HOWEVER, that nothing in this
Section shall prevent the Company from discontinuing the operation or main-
tenance of any of such properties if such discontinuance is, in the judgment
of the Company, desirable in the conduct of its business and not disadvan-
tageous in any material respect to the Holders.

Section 1007.  PAYMENT OF TAXES AND OTHER CLAIMS.

          The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Company or upon the income,

contested in good faith by appropriate proceedings.

Section 1008.  LIMITATION ON DIVIDENDS; TRANSACTIONS WITH
               AFFILIATES.

          (a)  If Securities are issued to the Trust or a trustee of the Trust
     in connection with the issuance of Trust Securities by the Trust and (i)
     there shall have occurred any event that would constitute an Event of
     Default or (ii) the Company shall be in default with respect to its
     payment of any other obligations under the Preferred Securities Guarantee
     or Common Securities Guarantee relating to the Trust, then (A) the
     Company shall not declare or pay any dividend on, make any distributions
     with respect to, or redeem, purchase or acquire or make a liquidation
     payment with respect to, any of its capital stock and (B) the Company
     shall not make any payment of interest, principal or premium, if any, on
     or repay, repurchase or redeem any debt securities issued by the Company
     which rank pari passu with or junior to such Securities, provided that
     the foregoing restriction in paragraph (A) does not apply to any stock
     dividends paid by the Company where the dividend stock is the same stock
     as that on which the dividend is being paid.

          (b)  If Securities are issued to the Trust or a trustee of the Trust
     in connection with the issuance of Trust Securities by the Trust and the
     Company shall have given notice of its election to defer payments of
     interest on such Securities by extending the interest payment period as
     provided in the Indenture and such period, or any extension thereof,
     shall be continuing, then (A) the Company shall not declare or pay any
     dividend on, make any distributions with respect to, or redeem, purchase
     or acquire or make a liquidation payment with respect to, any of its
     capital stock and (B) the Company shall not make any payment of interest,
     principal or premium, if any, on or repay, repurchase or redeem any debt
     securities issued by the Company which rank pari passu with or junior to
     such Securities, provided that the foregoing restriction in paragraph (A)
     does not apply to any stock dividends paid by the Company where the
     dividend stock is the same as that on which the dividend is being paid.

Section 1009.  COVENANTS AS TO THE TRUST.

          In the event Securities are issued and sold to the Trust or a
trustee of the Trust in connection with the issuance of Trust Securities by
the Trust, for so long as such Trust Securities remain outstanding, the
Company will (i) maintain 100% direct or indirect ownership of the Common
Securities of the Trust; provided, however, that any permitted successor of

                                       64
 74                                       
the Company under the Indenture may succeed to the Company's ownership of the
Common Securities, and (ii) use its reasonable efforts to cause the Trust (a)
to remain a statutory business trust, except in connection with a distribution
of Securities as provided in the Declaration of the Trust, the redemption of
all of the Trust Securities and in connection with certain mergers,
consolidations or amalgamations permitted by the Declaration of the Trust, and
(b) otherwise continue to be treated as a grantor trust for United States
federal income tax purposes.

                                ARTICLE ELEVEN

                           REDEMPTION OF SECURITIES

Section 1101.  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 301 for Securities of any
series) in accordance with this Article.

Section 1102.  ELECTION TO REDEEM; NOTICE TO TRUSTEE.

          The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution.  In case of any redemption at the election of
the Company of less than all the Securities of any series, the Company shall,
at least 45 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of
such Redemption Date, of the principal amount of Securities of such series to
be redeemed and, if applicable, of the tenor of the Securities 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 1103.  SELECTION BY TRUSTEE OF 
               SECURITIES TO BE REDEEMED.

          If less than all the Securities of any series are to be redeemed
(unless all of the Securities of such series and of a specified tenor are to
be redeemed), the particular Securities to be redeemed shall be selected not
more than 45 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities of such series 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 to the minimum
authorized denomination for Registered Securities of that series or any
integral multiple thereof) of the principal amount of Registered Securities of

                                       65
 75                                       
such series of a denomination larger than the minimum authorized denomination
for Registered Securities of that series.  If less than all of the Securities
of such series and of a specified tenor 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
and specified tenor not previously called for redemption in accordance with
the preceding sentence.

          The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

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

Section 1104.  NOTICE OF REDEMPTION.

          Notice of redemption shall be given in the manner provided in
Section 106, not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed.

          All notices of redemption shall state:

          (1)  the Redemption Date,

          (2)  the Redemption Price,

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

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

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

          (6)  that the redemption is for a sinking fund, if such is the case,
          
                                       66
          
                                       
          (7)  if applicable, the conversion price and the date on which the
     right to convert the Securities to be redeemed will terminate,

          (8)  that, unless otherwise specified in such notice, Bearer
     Securities of any series, if any, surrendered for redemption must be
     accompanied by all Coupons maturing subsequent to the date fixed for
     redemption or the amount of any such missing Coupon or Coupons will be
     deducted from the Redemption Price, unless security or indemnity
     satisfactory to the Company, the Trustee and any Paying Agent is
     furnished,

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

          (10) the CUSIP numbers of the Securities to be redeemed.

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

Section 1105.  DEPOSIT OF REDEMPTION PRICE.

          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, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date.  

Section 1106.  SECURITIES PAYABLE ON REDEMPTION DATE.

          Notice of redemption having been given as aforesaid, the Securities
so to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest and the Coupons for
such interest appertaining to any Bearer Securities to be redeemed, except as
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

                                       67
 77                                       
be paid by the Company at the Redemption Price, together with accrued interest
on Registered Securities to the Redemption Date; PROVIDED, HOWEVER, that,
unless otherwise specified as contemplated by Section 301, installments of
interest 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 307 and PROVIDED,
FURTHER, that installments of interest on Bearer Securities whose Stated
Maturity is on or prior to the Redemption Date shall be payable only upon
presentation and surrender of Coupons for such interest at an office or agency
located outside of the United States except as otherwise provided in Section
1002.

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

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

Section 1107.  SECURITIES REDEEMED IN PART.

          Any Registered Security which is to be redeemed only in part shall
be surrendered at 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 duly executed by, the
Holder thereof or his attorney duly authorized in writing), and the Company
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Registered Security without service charge, a new Registered Security or
Securities of the same series and of like tenor, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal
to and in exchange for the unredeemed portion of the principal of the Security
so surrendered.

                                       68

                                ARTICLE TWELVE

                                SINKING FUNDS

Section 1201.  APPLICABILITY OF ARTICLE.

          The provisions of this Article shall be applicable to any sinking
fund for the retirement of Securities of a series except as otherwise
specified as contemplated by Section 301 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 Securities of any series is herein referred to as
an "optional sinking fund payment".  If provided for by the terms of
Securities of any series, the cash amount of any sinking fund payment may be
subject to reduction as provided in Section 1202.  Each sinking fund payment
shall be applied to the redemption of Securities of any series as provided for
by the terms of Securities of such series.

Section 1202.  SATISFACTION OF SINKING 
               FUND PAYMENTS WITH SECURITIES.

          The Company (1) may deliver Outstanding Securities of a 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) may apply as a credit Securities of a 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, in each case in satis-
faction of all or any part of any sinking fund payment with respect to the
Securities of such series required to be made pursuant to the terms of such
Securities as provided for by the terms of such series; provided that such
Securities have not been previously so credited.  Such Securities shall be
received and credited for such purpose by the Trustee at the Redemption Price
specified in such Securities for redemption through operation of the sinking
fund and the amount of such sinking fund payment shall be reduced accordingly.

Section 1203.  REDEMPTION OF SECURITIES FOR SINKING FUND.

          Not less than 60 days prior to each sinking fund payment date for
any series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash and the portion thereof, if any,

                                       69
 79                                       
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 1202 and will also deliver to the Trustee any Securities
to be so delivered.  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 1103 and
cause notice of the redemption thereof to be given in the name of and at the
expense of the Company in the manner provided in Section 1104.  Such notice
having been duly given, the redemption of such Securities shall be made upon
the terms and in the manner stated in Sections 1106 and 1107.


                               ARTICLE THIRTEEN

                      DEFEASANCE AND COVENANT DEFEASANCE

Section 1301.  COMPANY'S OPTION TO EFFECT 
               DEFEASANCE OR COVENANT DEFEASANCE.

          The Company may elect, at its option by Board Resolution at any
time, to have either Section 1302 or Section 1303 applied to the Outstanding
Securities of any series and any Coupons appertaining thereto designated
pursuant to Section 301 as being defeasible pursuant to this Article Thirteen
(hereinafter called a "Defeasible Series"), upon compliance with the
conditions set forth below in this Article Thirteen; provided, that the
Company shall not effect any such defeasance under Section 1302 or Section
1303 in respect of any Securities of which the Trust or a trustee of the Trust
is a Holder.

Section 1302.  DEFEASANCE AND DISCHARGE.

          Upon the Company's exercise of the option provided in Section 1301
to have this Section 1302 applied to the Outstanding Securities and any
Coupons appertaining thereto of any Defeasible Series, the Company shall be
deemed to have been discharged from its obligations with respect to the
Outstanding Securities of such series and any Coupons appertaining thereto as
provided in this Section on and after the date the conditions set forth in
Section 1304 are satisfied (hereinafter called "Defeasance").  For this
purpose, such Defeasance means that the Company shall be deemed to have paid
and discharged the entire indebtedness represented by the Outstanding
Securities of such series and any Coupons appertaining thereto and to have
satisfied all its other obligations under the Securities of such series and
any Coupons appertaining thereto and this Indenture insofar as the Securities
of such series and any Coupons appertaining thereto are concerned (and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), subject to the following which shall survive until

                                       70
 80                                       
otherwise terminated or discharged hereunder:  (1) the rights of Holders of
Securities of such series and any Coupons appertaining thereto to receive,
solely from the trust fund described in Section 1304 and as more fully set
forth in such Section, payments in respect of the principal of and any premium
and interest on such Securities of such series and any Coupons appertaining
thereto when payments are due, (2) the Company's obligations with respect to
the Securities of such series and any Coupons appertaining thereto under
Sections 304, 305, 306, 1002 and 1003, (3) the rights, powers, trusts, duties
and immunities of the Trustee hereunder and (4) this Article Thirteen. 
Subject to compliance with this Article Thirteen, the Company may exercise its
option provided in Section 1301 to have this Section 1302 applied to the
Outstanding Securities and any Coupons appertaining thereto of any Defeasible
Series notwithstanding the prior exercise of its option provided in Section
1301 to have Section 1303 applied to the Outstanding Securities of such series
and any Coupons appertaining thereto.

Section 1303.  COVENANT DEFEASANCE.

          Upon the Company's exercise of the option provided in Section 1301
to have this Section 1303 applied to the Outstanding Securities and any
Coupons appertaining thereto of any Defeasible Series, (i) the Company shall
be released from its obligations under Sections 1005 through 1007, inclusive,
and any other covenants specified in or pursuant to this Indenture, and (2)
the occurrence of any event specified in Sections 501(4) (with respect to any
of Sections 1005 through 1007, inclusive, and any other covenants specified in
or pursuant to this Indenture), 501(5) and 501(9) shall be deemed not to be or
result in an Event of Default, in each case with respect to the Outstanding
Securities of such series and any Coupons appertaining thereto as provided in
this Section on and after the date the conditions set forth in Section 1304
are satisfied (hereinafter called "Covenant Defeasance").  For this purpose,
such Covenant Defeasance means that 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 specified Section (to the extent so specified in the case of
Section 501(4)), whether directly or indirectly by reason of any reference
elsewhere herein to any such Section or by reason of any reference in any such
Section to any other provision herein or in any other document, but the
remainder of this Indenture and the Securities of such series and any Coupons
appertaining thereto shall be unaffected thereby.

Section 1304.  CONDITIONS TO DEFEASANCE 
               OR COVENANT DEFEASANCE. 

          The following shall be the conditions to application of either
Section 1302 or Section 1303 to the Outstanding Securities and any Coupons
appertaining thereto of any Defeasible Series:

                                      71
               
 81                                       
          (1)  The Company shall irrevocably have deposited or caused to be
     deposited with the Trustee (or another trustee that satisfies the
     requirements contemplated by Section 609 and agrees to comply with the
     provisions of this Article Thirteen 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 Outstanding Securities of such series and any Coupons
     appertaining thereto, (A) money in an amount, or (B) U.S. Government
     Obligations that through the scheduled payment of principal and interest
     in respect thereof in accordance with their terms will provide, not later
     than one day before the due date of any payment, money in an amount, or
     (C) a combination thereof, in each case sufficient, in the opinion of a
     nationally recognized firm of independent public accountants expressed in
     a written certification thereof delivered to the Trustee, to pay and
     discharge, and which shall be applied by the Trustee (or any such other
     qualifying trustee) to pay and discharge, the principal of and any
     premium and interest on the Securities of such series and any Coupons
     appertaining thereto on the respective Stated Maturities, in accordance
     with the terms of this Indenture and the Securities of such series and
     any Coupons appertaining thereto.  As used herein, "U.S. Government
     Obligation" means (x) any security that is (i) a direct obligation of the
     United States of America for the payment of which the full faith and
     credit of the United States of America is pledged or (ii) an obligation
     of a Person controlled or supervised by and acting as an agency or
     instrumentality of the United States of America the payment of which is
     unconditionally guaranteed as a full faith and credit obligation by the
     United States of America, which, in either case (i) or (ii), is not
     callable or redeemable at the option of the issuer thereof, and (y) any
     depositary receipt issued by a bank (as defined in Section 3(a)(2) of the
     Securities Act of 1933, as amended) as custodian with respect to any U.S.
     Government Obligation specified in Clause (x) and held by such custodian
     for the account of the holder of such depositary receipt, or with respect
     to any specific payment of principal of or interest on any such U.S.
     Government Obligation, provided that (except as required by law) such
     custodian is not authorized to make any deduction from the amount payable
     to the holder of such depositary receipt from any amount received by the
     custodian in respect of the U.S. Government Obligation or the specific
     payment of principal or interest evidenced by such depositary receipt.

          (2)  In the case of an election under Section 1302, the Company
     shall have delivered to the Trustee an Opinion of Counsel stating that
     
                                       72
     
 82                                       
     (A) the Company has received from, or there has been published by, the
     Internal Revenue Service a ruling or (B) since the date first set forth
     hereinabove, there has been a change in the applicable Federal income tax
     law, in either case (A) or (B) to the effect that, and based thereon such
     opinion shall confirm that, the Holders of the Outstanding Securities of
     such series and any Coupons appertaining thereto will not recognize gain
     or loss for Federal income tax purposes as a result of the deposit,
     Defeasance and discharge to be effected with respect to the Securities of
     such series and any Coupons appertaining thereto and will be subject to
     Federal income tax on the same amount, in the same manner and at the same
     times as would be the case if such deposit, Defeasance and discharge were
     not to occur.

          (3)  In the case of an election under Section 1303, the Company
     shall have delivered to the Trustee an Opinion of Counsel to the effect
     that the Holders of the Outstanding Securities of such series and any
     Coupons appertaining thereto will not recognize gain or loss for Federal
     income tax purposes as a result of the deposit and Covenant Defeasance to
     be effected with respect to the Securities of such series and any Coupons
     appertaining thereto and will be subject to Federal income tax on the
     same amount, in the same manner and at the same times as would be the
     case if such deposit and Covenant Defeasance were not to occur.

          (4)  The Company shall have delivered to the Trustee an Officer's
     Certificate to the effect that the Securities of such series, if then
     listed on any securities exchange, will not be delisted as a result of
     such deposit.

          (5)  No Event of Default or event that (after notice or lapse of
     time or both) would become an Event of Default shall have occurred and be
     continuing at the time of such deposit or, with regard to any Event of
     Default or any such event specified in Sections 501(6), (7) and (8), at
     any time on or prior to the 90th day after the date of such deposit (it
     being understood that this condition shall not be deemed satisfied until
     after such 90th day).

          (6)  Such Defeasance or Covenant Defeasance shall not cause the
     Trustee to have a conflicting interest within the meaning of the Trust
     Indenture Act (assuming all Securities are in default within the meaning
     of the Trust Indenture Act).

          (7)  Such Defeasance or Covenant Defeasance shall not result in a
     breach or violation of, or constitute a default under, any other
     agreement or instrument to which the Company is a party or by which it is
     bound.

 83                                       
          (8)  The Company shall have delivered to the Trustee an Officer's
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent with respect to such Defeasance or Covenant Defeasance have
     been complied with.

          (9)  Such Defeasance or Covenant Defeasance shall not result in the
     trust arising from such deposit constituting an investment company within
     the meaning of the Investment Company Act of 1940, as amended, unless
     such trust shall be qualified under such Act or exempt from regulation
     thereunder.

Section 1305.  DEPOSITED MONEY AND U.S. GOVERNMENT
               OBLIGATIONS TO BE HELD IN TRUST;
               OTHER MISCELLANEOUS PROVISIONS.    

          Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee or other qualifying trustee (solely for purposes of
this Section and Section 1306, the Trustee and any such other trustee are
referred to collectively as the "Trustee") pursuant to Section 1304 in respect
of the Securities and any Coupons appertaining thereto of any Defeasible
Series shall be held in trust and applied by the Trustee, in accordance with
the provisions of the Securities of such series and any Coupons appertaining
thereto and this Indenture, to the payment, either directly or through any
such Paying Agent (including the Company acting as its own Paying Agent) as
the Trustee may determine, to the Holders of Securities of such series and any
Coupons appertaining thereto, of all sums due and to become due thereon in
respect of principal and any premium and interest, but money so held in trust
need not be segregated from other funds except to the extent required by law.

          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1304 or the principal and interest received in
respect thereof other than any such tax, fee or other charge that by law is
for the account of the Holders of Outstanding Securities and any Coupons
appertaining thereto.

          Anything in this Article Thirteen to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 1304 with respect to Securities and any Coupons appertaining thereto
of any Defeasible Series that, 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 that would then
be required to be deposited to effect an equivalent Defeasance or Covenant

                                       74
 84                                       
Defeasance with respect to the Securities of such series and any Coupons
appertaining thereto.

Section 1306.  REINSTATEMENT.

          If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article Thirteen with respect to the Securities of any
series and any Coupons appertaining thereto by reason of any order or judgment
of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, then the Company's obligations under this
Indenture and the Securities of such series and any Coupons appertaining
thereto shall be revived and reinstated as though no deposit had occurred
pursuant to this Article Thirteen with respect to Securities of such series or
any Coupons appertaining thereto until such time as the Trustee or Paying
Agent is permitted to apply all money held in trust pursuant to Section 1305
with respect to Securities of such series and any Coupons appertaining thereto
in accordance with this Article Thirteen; PROVIDED, HOWEVER, that if the
Company makes any payment of principal of or any premium or interest on any
Security of such series or any Coupons appertaining thereto following the
reinstatement of its obligations, the Company shall be subrogated to the
rights of the Holders of Securities of such series and any Coupons
appertaining thereto to receive such payment from the money so held in trust.

Section 1401.  PURPOSE FOR WHICH MEETINGS MAY BE CALLED.

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

forth in reasonable detail the action proposed to be taken at the meeting, and
the Trustee shall not have made the first publication of the notice of such
meeting within 21 days after receipt of such request or shall not thereafter
proceed to cause the meeting to be held as provided herein, then the Company

 86                                       
of such meeting.  In the absence of a quorum at any such adjourned meeting,
such adjourned meeting may be further adjourned for a period of not less than
10 days as determined by the chairman of the meeting prior to the adjournment
of such adjourned meeting.  Notice of the reconvening of any adjourned meeting
shall be given as provided in Section 1402(a), except that such notice need be

          Except as limited by the proviso to Section 902, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum
is present as aforesaid may be adopted only by the affirmative vote of the
Holders of a majority in principal amount of the Outstanding Securities of
that series, PROVIDED, HOWEVER, that, except as limited by the proviso to
Section 902, any resolution with respect to any request, demand,
authorization, direction, notice, consent, waiver or other action which this
Indenture expressly provides may be made, given or taken by the Holders of a
specified percentage, which is less than a majority, in principal amount of

appertaining thereto, whether or not present or represented at the meeting.

Section 1405.  DETERMINATION OF VOTING RIGHTS; 
               CONDUCT AND ADJOURNMENT OF MEETINGS.

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

                                       77
          
 87                                       
          (b)  The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called
by the Company or by Holders of Securities as provided in Section 1402(b), in
which case the Company or the Holders of Securities of the series calling the
meeting, as the case may be, shall in like manner appoint a temporary
chairman.  A permanent chairman and a permanent secretary of the meeting shall
be elected by vote of the Persons entitled to vote a majority in principal
amount of the Outstanding Securities of such series represented at the
meeting.

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

          (d)  Any meeting of Holders of Securities of any series duly called
pursuant to Section 1402 at which a quorum is present may be adjourned from
time to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

Section 1406.  COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

          The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them.  The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and
who shall make and file with the secretary of the meeting their verified
written reports in triplicate of all votes cast at the meeting.  A record, at
least in triplicate, of the proceedings of each meeting of Holders of
Securities of any series shall be prepared by the secretary of the meeting and
there shall be attached to said record the original reports of the inspectors
of votes on any vote by ballot taken thereat and affidavits by one or more
persons having knowledge of the facts setting forth a copy of the notice of
the meeting and showing that said notice was given as provided in Section 1402
and, if applicable, Section 1404.  Each copy shall be signed and verified by
the affidavits of the permanent chairman and secretary of the meeting and one
such copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots

                                       78
 88                                       
voted at the meeting.  Any record so signed and verified shall be conclusive
evidence of the matters therein stated.

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

                                       79

          IN WITNESS WHEREOF, the parties hereto have caused this Indenture to
be duly executed, and their respective corporate seals to be hereunto affixed
and attested, all as of the day and year first above written.
