waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company.  Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments.  Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

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

          (c)  The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining the
Holders entitled to

                                      -21-


give or take any request, demand, authorization, direction, notice, consent,
waiver or other action, or to vote on any action, authorized or permitted to be
given or taken by Holders.  If not set by the Company prior to the first
solicitation of a Holder made by any Person in respect of any such action, or,
in the case of any such vote, prior to such vote, the record date for any such
action or vote shall be the 30th day (or, if later, the date of the most recent
list of Holders required to be provided pursuant to Section 701) prior to such
first solicitation or vote, as the case may be.  With regard to any record date,
only the Holders on such date (or their duly designated proxies) shall be
entitled to give or take, or vote on, the relevant action.

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

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


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, Attention:  
     Administration, or

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

                                      -22-

 
     previously furnished in writing to the Trustee by the Company.


SECTION 106.  Notice to Holders; Waiver.
              ------------------------- 

          Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice.  In any case where notice to Holders
is given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders.  Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice.  Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

          In case by reason of the suspension of 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.


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 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.

                                      -23-

 

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


SECTION 111.  Benefits of Indenture.
              --------------------- 

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


SECTION 112.  GOVERNING LAW.
              ------------- 

          THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.


SECTION 113.  Legal Holidays.
              -------------- 

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

Date or Stated Maturity, as the case may be.

any overdue installment of interest until paid.  The interest so payable, and
punctually paid or duly provided for, on any Interest Payment Date will, as
provided in such Indenture,

paid or duly provided for will forthwith cease to be payable to the Holder on
such Regular Record Date and may either be paid to the Person in whose name this
Security (or one or more Predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to
be fixed by the Trustee, notice whereof shall be given to Holders of Securities
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities may be listed, and upon such notice

address of the Person entitled thereto as such address shall appear in the

set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

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

to such Redemption Date will be payable to the Holders of such Securities, or
one or more Predecessor Securities, of record at the close of business on the
relevant Record Dates referred to on the face hereof, all as provided in the
Indenture.

        The Securities do not have the benefit of any sinking fund obligations.

          In the event of redemption or purchase pursuant to an Offer to
Purchase of this Security in part only, a new Security or Securities for the
unredeemed or unpurchased portion hereof will be issued in the name of the
Holder, or the Person designated by such Holder, hereof upon the cancellation

effect provided in the Indenture.

          The Indenture provides that if a Change of Control occurs the Company
shall be required to make an Offer to Purchase all of the Securities.

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

                                      -28-


hereof, whether or not notation of such consent or waiver is made upon this
Security.

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

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

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

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

          Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security be overdue, and neither

contrary.

          The Securities shall be executed on behalf of the Company by its
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.  The signature of any of these officers on the Securities

Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder.


SECTION 304.  Temporary Securities.
              -------------------- 

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

                                      -32-

 
officers executing such Securities may determine, as evidenced by their
execution of such Securities.

          If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay.  After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Company designated pursuant to Section 1002, without charge to
the Holder.  Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities
of authorized denominations.  Until so exchanged the temporary Securities shall
in all respects be entitled to the same benefits under this Indenture as
definitive Securities.


SECTION 305.  Registration, Registration of Transfer and
              ------------------------------------------
              Exchange.
              -------- 

          The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant to Section 1002 being herein sometimes
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 Securities.  The Trustee is
hereby appointed "Security Registrar" for the purpose of registering Securities
and transfers of Securities as herein provided.

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

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

                                      -33-


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

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

          No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1108 or in accordance with any Offer
to Purchase pursuant to Section 1015 not involving any transfer.

          The Company shall not be required (i) to issue, register the transfer
of or exchange any Security during a period beginning at the opening of business
15 days before the day of the mailing of a notice of redemption of Securities
selected for redemption under Section 1104 and ending at the close of business
on the day of such mailing, or (ii) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.


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

          If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

          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 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 has been acquired by a
bona fide purchaser, the

                                      -34-


Company shall execute and upon its request the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of like tenor and principal amount and bearing a number not contemporaneously
outstanding.

          If after the delivery of such new Security, a bona fide purchaser of
the original Security in lieu of which such new Security was issued presents for
payment such original Security, the Company and the Trustee shall be entitled to
recover such new Security from the person to whom it was delivered or any
transferee thereof, except a bona fide purchaser, and shall be entitled to
recover upon the security or indemnity provided therefor to the extent of any
loss, damage, cost or expense incurred by the Company or the Trustee in
connection therewith.

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

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

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

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


SECTION 307.  Payment of Interest; Interest
              -----------------------------
              Rights Preserved.
              ---------------- 

          Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Security (or one or more Predecessor Securities) is regis-

                                      -35-


tered at the close of business on the Regular Record Date for such interest.

          Any interest on any Security 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 Securities (or their respective
     Predecessor Securities) are registered at the close of business on a
     Special Record Date for the payment of such Defaulted Interest, which shall
     be fixed in the following manner.  The Company shall notify the Trustee in
     writing of the amount of Defaulted Interest proposed to be paid on each
     Security and the date of the proposed payment, and at the same time the
     Company shall deposit with the Trustee an amount of money equal to the
     aggregate amount proposed to be paid in respect of such Defaulted Interest
     or shall make arrangements satisfactory to the Trustee for such deposit
     prior to the date of the proposed payment, such money when deposited to be
     held in trust for the benefit of the Persons entitled to such Defaulted
     Interest as in this Clause provided.  Thereupon the Trustee shall fix a
     Special Record Date for the payment of such Defaulted Interest which shall
     be not more than 15 days and not less than 10 days prior to the date of the
     proposed payment and not less than 10 days after the receipt by the
     Trustee of the notice of the proposed payment.  The Trustee shall promptly
     notify the Company of such Special Record Date and, in the name and at the
     expense of the Company, shall cause notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor to be mailed,
     first-class postage prepaid, to each Holder 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 hav-

                                      -36-


     ing been so mailed, such Defaulted Interest shall be paid to the Persons in
     whose names the Securities (or their respective Predecessor Securities)
     are registered at the close of business on such Special Record Date and
     shall no longer be payable pursuant to the following Clause (2).

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

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


SECTION 308.  Persons Deemed Owners.
              --------------------- 

          Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of (and premium, if
any) and (subject to Section 307) 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.


SECTION 309.  Cancellation.
              ------------ 

          All Securities surrendered for payment, redemption, registration of
transfer or exchange or any Offer to Purchase pursuant to Section 1015 shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly cancelled by it.  The Company may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner whatso-

                                      -37-

 
ever, and all Securities so delivered shall be promptly cancelled by the
Trustee.  No Securities shall be authenticated in lieu of or in exchange for
any Securities cancelled as provided in this Section, except as expressly
permitted by this Indenture.  All cancelled Securities held by the Trustee shall
be disposed of in accordance with the Trustee's customary practices unless
otherwise directed by a Company Order.


SECTION 310.  Computation of Interest.
              ----------------------- 

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

                           Satisfaction and Discharge

SECTION 401.  Satisfaction and Discharge of Indenture.
              --------------------------------------- 

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

          (1)  either

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

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

               (i)  have become due and payable, or

                                      -38-


               (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 that purpose an amount sufficient to pay and discharge the
          entire indebtedness on such Securities not theretofore delivered to
          the Trustee for cancellation, for principal (and premium, if any) 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 pursuant to
this Article Four, the obligations of the Company to the Trustee under Section
607 and, if money shall have been deposited with the Trustee pursuant to sub-
clause (B) of Clause (1) of this Section, the obligations of the Trustee under
Section 402 and the last paragraph of Section 1003 shall survive.


SECTION 402.  Application of Trust Money.
              -------------------------- 

          Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
(without liability for the payment of interest thereon or the investment
thereof)

                                      -39-


and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may deter-
mine, to the Persons entitled thereto, of the principal (and premium, if any)
and interest for whose payment such money has been deposited with the Trustee.

SECTION 502.  Acceleration of Maturity; Rescission
              ------------------------------------
              and Annulment.
              ------------- 

          If an Event of Default (other than an Event of Default specified in
Section 501(8) or (9)) occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities may declare the principal of all the Securities 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 and
any accrued interest shall become immediately due and payable.  If an Event of
Default specified in Section 501(8) or (9) occurs, the principal of and any
accrued interest on the Securities then Outstanding shall ipso facto become
                                                          ---- -----       
immediately due and payable without any declaration or other Act on the part of
the Trustee or any Holder.

          At any time after such a declaration of acceleration 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, 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,

               (B)  the principal of (and premium, if any, on) any Securities
          which have become due otherwise than by such declaration of
          acceleration (including any Securities required to have been pur-
          chased on the Purchase Date pursuant to an Offer to Purchase made by
          the Company) and, to the extent that payment of such interest is
          lawful, interest thereon at the rate provided by the Securities,

                                      -43-


               (C)  to the extent that payment of such interest is lawful,
          interest upon overdue interest at the rate provided by the Securities,
          and

               (D)  all sums paid or advanced by the Trustee hereunder and all
          amounts owing under Section 607;

     and

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

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


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
     when such interest becomes due and payable and such default continues for
     a period of 30 days, or

          (2)  default is made in the payment of the principal of (or premium,
     if any, on) any Security at the Maturity thereof or, with respect to any
     Security required to have been purchased pursuant to an Offer to Purchase
     made by the Company, at the Purchase Date thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest, and, to the extent
that payment of such interest shall be legally enforceable, interest on any
overdue principal (and premium, if any) and on any overdue interest, at the rate
provided by the Securities, and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection and all
amounts owing the Trustee under Section 607.

                                      -44-


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

          If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and 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), 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 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 all amounts due it 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 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.

              Without Possession of Securities.
              -------------------------------- 

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


SECTION 506.  Application of Money Collected.
              ------------------------------ 

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

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

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


SECTION 507.  Limitation on Suits.
              ------------------- 

          No Holder of any Security 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;

                                      -46-


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

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

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

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

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the 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 shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to Sec-
tion 307) interest on such Security on the respective Stated Maturities
expressed in such Security (or, in the case of redemption, on the Redemption
Date or, in the case of an Offer to Purchase made by the Company and required to
be accepted as to such Security, on the Purchase 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.

                                      -47-


SECTION 509.  Restoration of Rights and Remedies.
              ---------------------------------- 

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


SECTION 510.  Rights and Remedies Cumulative.
              ------------------------------ 

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


SECTION 511.  Delay or Omission Not Waiver.
              ---------------------------- 

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


SECTION 512.  Control by Holders.
              ------------------ 

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

                                      -48-

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

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

          (3)  such direction shall not involve the Trustee in personal
     liability or be unjustly prejudicial to Holders not joining therein (it
     being understood that the Trustee shall have no responsibility to determine
     such prejudice).


SECTION 513.  Waiver of Past Defaults.
              ----------------------- 

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

          (1)  in the payment of the principal of (or premium, if any) or
     interest on any Security (including any Security which is required to have
     been purchased pursuant to an Offer to Purchase which has been made by the
     Company), or

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

          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

                                      -49-


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
Trustee or the Holders of at least 10% in aggregate principal amount of
Outstanding Securities.

SECTION 515.  Waiver of Stay or Extension Laws.
              -------------------------------- 

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


                                  ARTICLE SIX

                                  The Trustee

              ----------------------------------- 

          The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act.  Notwithstanding the foregoing, no provision of this
Indenture shall require 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 the Holders notice of any default hereunder as
and to the extent provided by the Trust

                                      -50-


Indenture Act; provided, however, that in the case of any default of the

character specified in Section 501(5), no such notice to Holders shall be given
until at least 30 days after the occurrence thereof.  For the purpose of this
Section, the term "default" means any event which is, or after notice or lapse
of time or both would become, an Event of Default.


SECTION 603.  Certain Rights of Trustee.
              ------------------------- 

          Subject to the provisions of Section 601:

     other evidence be herein specifically prescribed) may, in the absence of
     bad faith on its part, rely upon an Officers' Certificate;

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

          (e)  the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the

                                      -51-


     request or direction of any of the Holders pursuant to this Indenture,
     unless such Holders shall have offered to the Trustee reasonable security
     or indemnity against the costs, expenses and liabilities which might be
     incurred by it in compliance with such request or direction;

          (f)  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; and

          (g)  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
              ----------------------------

              ------------------------- 

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

                                      -52-


SECTION 605.  May Hold Securities.
              ------------------- 

          The Trustee, 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 and, subject to Sections 608 and 613, may other-
wise deal with the Company with the same rights it would have if it were not
Trustee, Paying Agent, Security Registrar or such other agent.


SECTION 606.  Money Held in Trust.
              ------------------- 

          Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law.  The Trustee shall be
under no liability for interest on or investment of any money received by it
hereunder except as otherwise agreed with the Company and any such interest or
investment shall be for the exclusive benefit of 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 to the extent any such
     expense, disbursement or advance may be attributable to its negligence or
     bad faith; and

          (3)  to indemnify the Trustee for, and to defend and hold it harmless
     against, any loss, liability or expense, arising out of or in connection
     with the acceptance or administration of this trust or the performance of
     its duties hereunder, including the costs and

                                      -53-


     expenses of defending itself against any claim or liability in connection
     with the exercise or performance of any of its powers or duties hereunder,
     except to the extent any such loss, liability or expense is attributable
     to its negligence or bad faith.

          To secure the Company's payment of obligations in this Section 607,
the Trustee shall have a lien prior to the Securities on all money or property
held or collected by the Trustee other than money or property held in trust to
pay principal of, premium, if any, and interest on the Securities.

          The Company's payment obligations pursuant to this Section 607 shall
survive the discharge of this Indenture.

          "Trustee" for purposes of this Section 607 includes the Trustee, every
predecessor Trustee, any Paying Agent, Security Registrar or other agent of the
Company appointed hereunder, but the negligence or bad faith of any such person
shall not affect the rights of any other such person under this Section 607.


SECTION 608.  Disqualification; Conflicting Interests.
              ---------------------------------------

Person that is eligible pursuant to the Trust Indenture Act to act as such and
has a combined capital and surplus of at least $50,000,000.  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 accordance with the provisions of this Section, it shall resign immediately
in the manner and with the effect hereinafter specified in this Article.

                                      -54-


 SECTION 610.  Resignation and Removal;
               ------------------------
              Appointment of Successor.
              ------------------------ 

          (a)  No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 611.

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

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

          (d)  If at any time:

          (1)  the Trustee shall fail to comply with 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, (i) the Company by a Board Resolution may remove the
Trustee, or (ii) 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 and the appointment of a successor Trustee.

                                      -55-


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

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


SECTION 611.  Acceptance of Appointment by Successor.
              -------------------------------------- 

          Every successor Trustee appointed hereunder shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee; but, on request of the Company or the suc-
cessor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder.  Upon request of any such successor Trustee,
the Company shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Trustee all such rights, powers and
trusts.

                                      -56-


          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.

          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.


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), the Trustee shall be subject to the

governmental charges levied or imposed upon the Company or any of its
Subsidiaries or upon the income, profits or property of the Company or any of
its Subsidiaries, and (2) all lawful claims for labor, materials and supplies

loss or damage with insurers believed by the Company to be responsible to the
extent that property of similar character is usually so insured by corporations
similarly situated and owning like properties in accordance with good business
practice.  The Company shall, and shall cause its Subsidiaries to, use the
proceeds from any such insurance policy to repair, replace or otherwise restore
the property to which such proceeds relate or, to the extent that any such

     defined in Section 3(a)(2) of the Securities Act of 1933, as amended) as
     custodian with respect to any such U.S. Government Obligation or a specific
     payment of principal of or interest on any such U.S. Government Obligation
     held by such custodian for the account of the holder of such depository
     receipt, provided that (except as required by law) such custodian is not
              --------                                                        
     authorized to make any deduction from the amount payable to the holder of
     such depository receipt from any amount received by the custodian in
     respect of the U.S. Government Obligation or the specific payment of
     principal of or interest on the U.S. Government Obligation evidenced by
     such depository receipt.

          (2)  In the case of an election under Section 1202, the Company shall
     have delivered to the Trustee an Opinion of Counsel stating that (x) the
     Company has received from, or there has been published by, the Internal
     Revenue Service a ruling, or

                                      -89-


     (y) since the date of this Indenture there has been a change in the
     applicable Federal income tax law, in either case to the effect that, and
     based thereon such opinion shall confirm that, the Holders of the
     Outstanding Securities will not recognize gain or loss for Federal income
     tax purposes as a result of such deposit, defeasance and discharge and will
     be subject to Federal income tax on the same amount, in the same manner and
     at the same times as would have been the case if such deposit, defeasance
     and discharge had not occurred.

          (3)  In the case of an election under Section 1203, the Company shall
     have delivered to the Trustee an Opinion of Counsel to the effect that the
     Holders of the Outstanding Securities will not recognize gain or loss for
     Federal income tax purposes as a result of such deposit and covenant
     defeasance and will be subject to Federal income tax on the same amount,
     in the same manner and at the same times as would have been the case if
     such deposit and covenant defeasance had not occurred.

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

          (5)  Such defeasance or covenant defeasance shall not cause the
     Trustee to have a conflicting interest as defined in Section 608 and for
     purposes of the Trust Indenture Act with respect to any securities of the
     Company.

          (6)  No Event of Default or event which with notice or lapse of time
     or both would become an Event of Default shall have occurred and be
     continuing on the date of such deposit or, insofar as subsections 501(8)
     and (9) are concerned, at any time during the period ending on the 121st
     day after the date of such deposit (it being understood that this condition
     shall not be deemed satisfied until the expiration of such period).

                                      -90-


          (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.

          (8)  The Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent provided for relating to either the defeasance under Section 1202
     or the covenant defeasance under Section 1203 (as the case may be) have
     been complied with.

          (9)  Such defeasance or covenant defeasance shall not result in the
     trust arising from such deposit constituting an investment company as
     defined in the Investment Company Act of 1940, as amended, or such trust
     shall be qualified under such act or exempt from regulation thereunder.


SECTION 1205.  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--collectively, for
purposes of this Section 1205, the "Trustee") pursuant to Section 1204 in
respect of the Securities shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Holders of
such Securities, of all sums due and to become due thereon in respect of
principal (and premium, if any) and any interest, but such money need not be
segregated from other funds except to the extent required by law.

          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1204 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the Outstanding Securities.

                                      -91-


          Anything in this Article Twelve 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 Sec-
tion 1204 which, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect an equivalent defeasance or covenant defeasance.


SECTION 1206.  Reinstatement.
               ------------- 

          If the Trustee or the Paying Agent is unable to apply any money in
accordance with Section 1202 or 1203 by  reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the Company's obligations under this Indenture and the
Securities shall be revived and reinstated as though no deposit had occurred
pursuant to this Article Twelve until such time as the Trustee or Paying Agent
is permitted to apply all such money in accordance with Section 1202 or 1203;
provided, however, that if the Company makes any payment of principal of (and
- --------  -------                                                            
premium, if any) or interest on any Security following the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of
such Securities to receive such payment from the money held by the Trustee or
the Paying Agent.
