signing such instrument or writing acknowledged to him the execution thereof.

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 ownership of Registered Securities shall be proved by the 
Security Register.

    (d)  Any request, demand, authorization, direction, notice, consent, 
waiver or other Act of the Holder of any Security shall bind every future

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.

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

    (a)  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 and received by the Trustee at its Corporate Trust Office, 
Attention: ______________________, or

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

    Where this Indenture or any Security provides for notice to Holders of 
any event, such notice shall be deemed sufficiently given (unless otherwise 
herein or in such Security 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, and not earlier than the earliest date, 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 or the validity of the proceedings to which such 
notice relates.  Where this Indenture or any Security 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.

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

    If any provision hereof limits, qualifies or conflicts with another 
provision hereof which is required to be included in this Indenture by any of 
the provisions of the Trust Indenture Act, such required 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 
shall be excluded, as the case may be.

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

thereby.

hereunder and the Holders, any benefit or any legal or equitable right, 
remedy or claim under this Indenture.

    This Indenture and the Securities shall be governed by and construed in 
accordance with the laws (other than the choice of law provisions) of the 
State of Minnesota.

SECTION 113.     Legal Holidays.

    In any case where any Interest Payment Date, Redemption 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 or of the 
Securities) 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, or on such other day as may be set  in an indenture 
supplemental hereto or in the Officer's Certificate delivered pursuant to 
Section 301, at such Place of Payment with the same force and effect as if 
made on the Interest Payment Date or Redemption Date, or at the Stated 
Maturity, provided that no interest shall accrue for the period from and 
after such Interest Payment Date, Redemption Date or Stated Maturity, as the 
case may be.

SECTION 114.     No Recourse Against Others.

    A director, officer, employee or stockholder, as such, of the Company 
shall not have any liability for any obligations of the Company under the 
Securities or this Indenture or for any claim based on, in respect of or by 
reason of such obligations or their creation.  Each Securityholder, by 
accepting a Security, waives and releases all such liability.  Such waivers 
and releases are part of the consideration for the issuance of the Securities.

Indenture also contains provisions permitting the Holders of a majority in 
principal amount of the Securities of each series at the time Outstanding, on 
behalf of the Holders of all Securities of such series, 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 bind such Holder and all future 
Holders of this Security and of any Security issued upon the registration of 
transfer hereof or in exchange hereof or in lieu 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

interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

                                       17



    As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Security Register,

agency of the Company in any place where the principal of (and premium, if any)
and interest on this Security are payable, 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 this series,
of authorized denominations and for the same Stated Maturity and aggregate
principal amount, will be issued to the designated transferee or transferees.

    The Securities of this series 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 of this series are exchangeable for a like aggregate principal amount
of Securities of this series 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.

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

covenants are applicable pursuant to the provisions of Section 301, insert
here].  All such covenants and limitations are subject to a number of important
qualifications and exceptions.  The Company must report periodically to the
Trustee on compliance with the covenants in the Indenture.

    A director, officer, employee or stockholder, as such, of the Company shall
not have any liability for any obligations of the Company under this Security or
the Indenture or for any claim based on, in respect of or by reason of, such
obligations or their creation.  Each Holder, by accepting a Security, waives and
releases all such liability.  The waiver and release are part of the
consideration for the issuance of this Security.

Committee on Uniform Security Identification Procedures ("CUSIP"), the Company
has caused CUSIP numbers to be printed on the Securities of this series as a
convenience to the Holders of the Securities of this series.  No representation

SECTION 205.    Securities in Global Form.

    If Securities of a series are issuable in global form, as contemplated by 
Section 301, then, notwithstanding the provisions of Section 302, any such 
Security shall represent such of the Outstanding Securities of such series as 
shall be specified therein and may provide that it shall represent the 
aggregate amount of Outstanding Securities from time to time endorsed thereon 
and that the aggregate amount of Outstanding Securities represented thereby 
may from time to time be reduced to reflect exchanges.  Any endorsement of a 
Security in global form to reflect the amount, or any increase or decrease in 
the amount, of Outstanding Securities represented thereby shall be made in 
such manner and upon instructions given by such Person or Persons as shall be 
specified therein or in the Company Order to be delivered to the Trustee 
pursuant to Section 303 or Section 304.  Subject to the provisions of Section 
303 and, if applicable, Section 304, the Trustee shall deliver and redeliver 
any Security in permanent global form in the manner and upon instructions 
given by the Person or Persons specified therein or in the applicable Company 
Order.  If a Company Order pursuant to Section 303 or 304 has been, or 
simultaneously is, delivered, any instructions by the Company with respect to 
endorsement or delivery or redelivery of a Security in global form shall be 
in writing but need not comply with Section 102 and need not be accompanied 
by an Opinion of Counsel.

    The provisions of Section 309 shall apply to any Security represented by 
a Security in global form if such Security was never issued and sold by the 
Company and the Company delivers to the Trustee the Security in global form 
together with written instructions (which need not comply with Section 102 
and need not be accompanied by an Opinion of Counsel) with regard to the 
reduction in the principal amount of Securities represented thereby.

    Notwithstanding the provisions of Sections 201 and 307, unless otherwise 
specified as contemplated by Section 301, payment of principal of, premium, 
if any, and interest on any Security in permanent global form shall be made 
to the Person or Persons specified therein.

                                       21



    Notwithstanding the provisions of Section 308 and except as provided in 
the preceding paragraph, the Company, the Trustee and any agent of the 
Company and the Trustee shall treat a Person as the Holder of such principal 
amount of Outstanding Securities represented by a permanent global Security as 
shall be specified in a written statement of the Holder of such permanent 
global Security.

SECTION 206.    CUSIP Number

    The Company in issuing Securities of any series may use a "CUSIP" number,
and, if so, the Trustee may use the CUSIP number in notices of redemption or
exchange as a convenience to Holders of such series; provided, that any such
notice may state that no representation is made as to the correctness or
accuracy of the CUSIP number printed on the notice or on the Securities of such
series, and that reliance may be placed only on the other identification numbers
printed on the Securities, and any such redemption shall not be affected by any
defect in or omission of such numbers.  The Company will promptly notify the
Trustee of any change in the CUSIP number of any series of Securities.

SECTION 207.    Form of Legend for the Securities in Global Form.  

    Any Security in global form authenticated and delivered hereunder shall 
bear a legend in substantially the following form:

    "This Security is in global form within the meaning of the Indenture 
hereinafter referred to and is registered in the name of a Common Depositary

case may be."

    and interest on, such Securities shall or may be payable; provided, 
    however, that prior to the issuance of any such Securities, the Company 
    shall have obtained the written consent of the Trustee, which consent may 
    be withheld in the sole discretion of the Trustee, to the currency, 
    currencies or currency units so established;
         
         (15) additional covenants with respect to Securities of the series, if
    any, other than those set forth herein;
         
         (16) if other than the Trustee, the identity of the Registrar and any
    Paying Agent; and
         
         (17) any other terms of the series (which terms shall not be
    inconsistent with the provisions of this Indenture).

    All Securities of any one series shall be substantially identical except as
to denomination and except as may otherwise be provided in or pursuant to such
Board Resolution and set forth in such Officer's Certificate 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 Officer's
Certificate setting forth, or providing the manner for determining, the terms of
the Securities of such series.

SECTION 302.    Denominations.

    The Securities of each series shall be issuable in registered form without
coupons in such denominations as shall be specified as contemplated by Section
301.  In the absence of any such provisions 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.

                                       24



SECTION 303.    Execution, Authentication, Delivery and Dating.

    The Securities shall be executed on behalf of the Company by 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 may be manual or facsimile.  The seal of
the Company may be in the form of a facsimile thereof and may be impressed,
affixed, imprinted or otherwise reproduced on the Securities.  Typographical and
other minor errors or defects in any such reproduction of the seal or any such
signature shall not affect the validity or enforceability of any Security that
has been duly authenticated and delivered by the Trustee.

    Securities 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 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 make such Securities available for
delivery.  If the form or terms of the Securities of the series 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,
the Trustee shall be entitled to receive, and (subject to Sections 315(a)
through (d) of the Trust Indenture Act) shall be fully protected in relying
upon, an Opinion of Counsel stating, 

    (a)  if the form of such Securities has been established by or pursuant to
Board Resolution as permitted by Section 201, that such form has been
established in conformity with the provisions of this Indenture;

    (b)  if the terms of such Securities 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;

    (c)  that such Securities, 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 valid and legally binding
obligations of the Company, enforceable in accordance with their terms, except
to the extent enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium and other similar laws affecting the
enforcement of creditors' rights generally and by the effect of general
principles of equity (regardless of whether enforceability is considered in a
proceeding in equity or at law); and

    (d)  that no consent, approval, authorization, order, registration or
qualification of or with any court or any governmental agency or body having
jurisdiction over the Company is 

                                       25



required for the execution and delivery of such Securities by the Company, 
except such as have been obtained (except that no opinion need be expressed 
as to state securities or Blue Sky laws).

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, or in the written opinion of
counsel to the Trustee (which counsel may be an employee of the Trustee) such
authentication may not lawfully be made or would involve the Trustee in personal
liability.

    Notwithstanding the provisions of Section 301 and of the immediately
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 Officer's
Certificate otherwise required pursuant to Section 301 or the Company Order and
Opinion of Counsel otherwise required pursuant to the immediately 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.

    If the Company shall establish pursuant to Section 301 that the Securities
of a series are to be issued in the form of one or more global Securities, then
the Company shall execute and the Trustee shall, in accordance with this Section
and the Company Order with respect to the authentication and delivery of such
series, authenticate and deliver one or more global Securities that (i) shall be
in an aggregate amount equal to the aggregate principal amount specified in such
Company Order, (ii) shall be registered in the name of the Common Depositary or
U.S. Depositary, as the case may be, therefor or its nominee, and (iii) shall be
made available for delivery by the Trustee to such depositary or pursuant to
such depositary's instruction.

    Each depositary designated pursuant to Section 301 must, at the time of its
designation and at all times while it serves as depositary, be a clearing agency
registered under the Exchange Act and any other applicable statute or
regulation.

    Unless otherwise provided for in the form of Security, each Security shall
be dated the date of its authentication.

    No Security 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 and is 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 make
available for delivery, temporary Securities which are printed, lithographed,
typewritten, mimeographed or otherwise 

                                       26



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

    In the case of Securities of any series, such temporary Securities may be 
in global form, representing all or a portion of the Outstanding Securities of 
such series.

    Except in the case of temporary Securities in global form (which shall be 
exchanged in accordance with the provisions of Section 305), if temporary 
Securities of any series are issued, the Company will cause definitive 
Securities of that series to be prepared with 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, the Company shall execute and the Trustee shall 
authenticate and make available for delivery in exchange therefor a like 
principal amount of definitive Securities of the same series of authorized 
denominations and of like tenor.  Until so exchanged, the temporary 
Securities of any series shall in all respects be entitled to the same 
benefits under this Indenture as definitive Securities of such series.

    If temporary Securities of any series are issued in global form, any such 
temporary global Security shall, unless otherwise provided therein, be 
delivered to the office of a depositary or common depositary (the "Common 
Depositary") for credit to the respective accounts of the beneficial owners 
of such Securities (or to such other accounts as they may direct).

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 registration 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 of any series
at the office or agency of the Company in Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and make available for
delivery, in the name of the designated transferee or transferees, one or more
new Securities of the same series, of any authorized denominations and of a like
aggregate principal amount and Stated Maturity.

    At the option of the Holder, Securities of any series may be exchanged for
other Securities of the same series, of any authorized denominations and of a
like aggregate principal amount and Stated Maturity, upon surrender of the
Securities to be exchanged at such office or 

                                       27



agency.  Whenever any Securities are so surrendered for exchange, the Company 
shall execute, and the Trustee shall authenticate and make available for 
delivery, the Securities which the Holder making the exchange is entitled to 
receive.

    Notwithstanding the foregoing, except as otherwise specified as 
contemplated by Section 301, any permanent global Security shall be 
exchangeable only as provided in this paragraph.  If the beneficial owners of 
interests in a permanent global Security are entitled to exchange such 
interests for Securities of such series and of like tenor and principal 
amount of another authorized form and denomination, as specified and as 
subject to the conditions contemplated by Section 301, then without unnecessary 
delay but in any event not later than the earliest date on which such 
interests may be so exchanged, the Company shall deliver to the Trustee 
definitive Securities of that series in aggregate principal amount equal to 
the principal amount of such permanent global Security, executed by the 
Company.  On or after the earliest date on which such interests may be so 
exchanged, such permanent global Securities shall be surrendered from time to 
time by the Common Depositary or the U.S. Depositary, as the case may be, and 
in accordance with instructions given to the Trustee and the Common 
Depositary or the U.S. Depositary, as the case may be (which instructions 
shall be in writing but need not comply with Section 102 or be accompanied by 
an opinion of Counsel), as shall be specified in the Company Order with 
respect thereto to the Trustee, as the Company's agent for such purpose, to 
be exchanged, in whole or in part, for definitive Securities of the same 
series without charge.  The Trustee shall authenticate and make available for 
delivery, in exchange for each portion of such surrendered permanent global 
Security, a like aggregate principal amount of definitive Securities of the 
same series of authorized denominations and of like tenor as the portion of 
such permanent global Security to be exchanged which shall be in the form of 
the Securities of such series; provided, however, that no such exchanges may 
occur 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.  Promptly following any such exchange in 
part, such permanent global Security shall be returned by the Trustee to the 
Common Depositary or the U.S. Depositary, as the case may be, or such other 
Common Depositary or U.S. Depositary referred to above in accordance with the 
written instructions of the Company referred to above.  If a Security in the 
form specified for such series is issued in exchange for any portion of a 
permanent global Security after the close of business at the office or agency 
where such exchange occurs on (i) any Regular Record Date and before the 
opening of business at such office or agency on the relevant Interest Payment 
Date, or (ii) any Special Record Date and before the opening of business at 
such office or agency on the related proposed date for payment of interest or 
Defaulted Interest, as the case may be, such interest or Defaulted Interest 
will not be payable on such Interest Payment Date or proposed date for 
payment, as the case may be, in respect of such Security in the form 
specified for such series, but will be payable on such Interest Payment Date 
or proposed date for payment, as the case may be, only to the Person to whom 
interest in respect of such portion of such permanent global Security is 
payable in accordance with the provisions of this Indenture.

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

                                       28



    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 
satisfactory to the Company and the Security Registrar duly executed, by the 
Holder thereof or his attorney duly authorized in writing.

    Unless otherwise provided in the Securities to be transferred or exchanged,
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 (i) 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 (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 the same series and 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 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 the same series and of like tenor and principal 
amount and bearing a number not contemporaneously outstanding.

    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 of any series issued pursuant to this Section in lieu 
of any destroyed, lost or stolen Security shall constitute an original 
additional contractual obligation of the 

                                       29



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 
of that series 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 registered at the
close of business on the Regular Record Date for such interest.

    Any interest on any 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 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 Security of such series 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 Section 307 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
    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 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).

                                       30




         (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 given by the Company to the Trustee of the proposed payment pursuant
    to this Section 307, 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.

    None of the Company, the Trustee or any agent of the Company or the 
Trustee shall have any responsibility or liability for any aspect of the 
records relating to or payments made on account of a beneficial ownership 
interest of a Security in global form, or for maintaining, supervising or 
reviewing any records relating to such beneficial ownership interest.  
Notwithstanding the foregoing, with respect to any Security in global form, 
nothing herein shall prevent the Company or the Trustee or any agent of the 
Company or the Trustee from giving effect to any written certification, proxy 
or other authorization furnished by any Common Depositary (or its nominee), 
as a Holder, with respect to such Security in global form or impair, as 
between such Common Depositary and owners of beneficial interests in such 
Security in global form, the operation of customary practices governing the 
exercise of the right of such Common Depositary (or its nominee) as holder of 
such Security in global form.

SECTION 309.    Cancellation.

    All Securities surrendered for payment, redemption, registration of 
transfer or exchange or for credit against any sinking fund payment shall, if 
surrendered to any Person other than the Trustee, be delivered to the Trustee 
and 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 
whatsoever, 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 shall be held by the 

                                       31



Trustee and may be destroyed (and, if so destroyed, certification of their 
destruction shall be delivered to the Company if requested in writing to do 
so, unless, by a Company Order, the Company shall direct that cancelled 
Securities be returned to it).

SECTION 310.     Computation of Interest. 

    Except as otherwise specified as contemplated by Section 301 for Securities
of any series, interest on the Securities of each series shall be computed on
the basis of a year of twelve 30-day months.
                                       
                                 ARTICLE FOUR

                           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 or in the form of Security for such series), when the
Trustee, upon Company Request 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 thereafter repaid to the Company or discharged from
such trust, as provided in Section 1009) 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
         
         (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 with the
Trustee as trust funds in trust for the 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 

                                       32



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 Officer's Certificate and
an Opinion of Counsel, each stating that all conditions precedent provided for
herein 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 Company to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1009 shall survive.

SECTION 402.    Application of Trust Money.

    Subject to the provisions of the last paragraph of Section 1009, 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 may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for whose payment such money has been deposited with or
received by the Trustee.
                                       
                                 ARTICLE FIVE

                                   REMEDIES

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 voluntary or involuntary or to 
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)  the Company defaults in the payment of interest on any Security of 
that series when such interest becomes due and payable and the default 
continues for a period of 30 days; provided, however that if the Company is 
permitted by the terms of the Securities of the applicable series to defer 
the payment in question, the date on which such payment is due and payable 
shall be the date on which the Company is required to make payment following 
such deferral, if such deferral has been elected pursuant to the terms of the 
Securities; or

                                       33



    (2)  the Company defaults in the payment of the principal of (or premium, 
if any, on) any Security of that series when the same becomes due and payable 
at Maturity, upon redemption (including redemptions under Article Eleven), or 
otherwise; provided, however, that if the Company is permitted by the terms 
of the Securities of the applicable series to defer the payment in question, 
the date on which such payment is due and payable shall be the date on which 
the Company is required to make payment following such deferral, if such 
deferral has been elected pursuant to the terms of the Securities; or

    (3)  the Company fails to observe or perform any of its other covenants, 
warranties or agreements in the Securities of that series or this Indenture 
(other than a covenant, agreement 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 one 
or more series of Securities other than that series), and the failure to 
observe or perform continues for the period and after the notice specified in 
the last paragraph of this Section; or

    (4)  the Company defaults in the payment of any Indebtedness at the 
maturity or acceleration thereof (after giving effect to any applicable grace 
period) or upon the acceleration thereof as a result of such Indebtedness 
becoming or being declared due and payable prior to the date on which it 
would otherwise become due and payable, and such default in payment is not 
cured or such acceleration shall not be rescinded or annulled within 10 days 
after written notice to the Company from the Trustee or to the Company and to 
the Trustee from the Holders of at least 10% in aggregate principal amount of 
the Securities of that series at the time outstanding; provided that it shall 
not be an Event of Default if the principal amount of Indebtedness (other 
than Indebtedness represented by Securities issued pursuant to this 
Indenture) which is not paid at maturity or the maturity of which is 
accelerated is less than the amount equal to 1% of the Company's consolidated 
total assets (determined as of its most recent fiscal year-end); provided 
further that if, prior to a declaration of acceleration of the maturity of 
the Securities of that series or the entry of judgment in favor of the 
Trustee in a suit pursuant to Section 503, such default shall be remedied or 
cured by the Company or waived by the holders of such Indebtedness, then the 
Event of Default hereunder by reason thereof shall be deemed likewise to have 
been thereupon remedied, cured or waived without further action upon the part of
either the Trustee or any of the Holders of the Securities of that series, 
and provided further, that, subject to Sections 601 and 602, the Trustee 
shall not be charged with knowledge of any such default unless written notice 
of such default shall have been given to the Trustee by the Company, by a 
holder or an agent of a holder of any such Indebtedness, by the trustee then 
acting under any indenture or other instrument under which such default shall 
have occurred, or by the Holders of at least five percent in aggregate 
principal amount of the Securities of that series at the time outstanding; or

    (5)  the Company pursuant to or within the meaning of any Bankruptcy Law 
(A) commences a voluntary case or proceeding under any Bankruptcy Law with 
respect to itself, (B) consents to the entry of a judgment, decree or order 
for relief against it in an involuntary case or proceeding under any 
Bankruptcy Law, (C) consents to or acquiesces in the institution of 
bankruptcy or insolvency proceedings against it, (D) applies for, consents to 
or acquiesces in the appointment of or taking possession by a Custodian of 
the Company or for any material part of 

                                       34



its property, (E) makes a general assignment for the benefit of its creditors 
or (F) takes any corporate action in furtherance of or to facilitate, 
conditionally or otherwise, any of the foregoing; or
    
    (6)  (i) a court of competent jurisdiction enters a judgment, decree or 
order for relief in respect of the Company in an involuntary case or 
proceeding under any Bankruptcy Law which shall (A) approve as properly filed 
a petition seeking reorganization, arrangement, adjustment or composition in 
respect of the Company, (B) appoint a Custodian of the Company or for any 
material part of its property or (C) order the winding-up or liquidation of 
its affairs, and such judgment, decree or order shall remain unstayed and in 
effect for a period of 60 consecutive days; or (ii) any bankruptcy or 
insolvency petition or application is filed, or any bankruptcy or insolvency 
proceeding is commenced against the Company and such petition, application or 
proceeding is not dismissed within 60 days; or (iii) a warrant of attachment 
is issued against any material portion of the property of the Company which 
is not released within 60 days of service; or 
    
    (7)  any other Event of Default provided with respect to Securities of that
series.

    A Default under clause (3) above is not an Event of Default until the
Trustee or the Holders of at least 25% in aggregate principal amount of the
Outstanding Securities of that series notify the Company of the Default and the
Company does not cure the Default within 60 days after receipt of the notice. 
The notice must specify the Default, demand that it be remedied and state that
the notice is a "Notice of Default." When a Default under clause (3) above is
cured within such 60-day period, it ceases.

SECTION 502.    Acceleration of Maturity; Rescission and Annulment.

    If an Event of Default with respect to Securities of any series (other 
than an Event of Default specified in clause (5) or (6) of Section 501) 
occurs and is continuing, the Trustee by notice in writing to the Company, or 
the Holders of at least 25% in aggregate principal amount of the Outstanding 
Securities of that series by notice in writing to the Company and the 
Trustee, may declare the unpaid principal of and accrued interest to the date 
of acceleration (or, if the Securities of that series are Original Issue 
Discount Securities, such portion of the principal amount as may be specified 
in the terms of that series) on all the Outstanding Securities of that series 
to be due and payable immediately and, upon any such declaration, the 
Outstanding Securities of that series (or specified principal amount) shall 
become and be immediately due and payable.

    If an Event of Default specified in clause (5) or (6) of Section 501 
occurs, all unpaid principal of and accrued interest on the Outstanding 
Securities of that series (or specified principal amount) shall ipso facto 
become and be immediately due and payable without any declaration or other act 
on the part of the Trustee or any Holder of any Security of that series.

                                       35



    Upon payment of all such principal and interest, all of the Company's
obligations under the Securities of that series and (upon payment of the
Securities of all series) this Indenture shall terminate, except obligations
under Section 607.

    The Holders of a majority in principal amount of the Outstanding Securities 
of that series by notice to the Trustee may rescind an acceleration and its 
consequences if (i) all existing Events of Default, other than the nonpayment 
of the principal and interest of the Securities of that series that has 
become due solely by such declaration of acceleration, have been cured or 
waived, (ii) to the extent the payment of such interest is lawful, interest 
on overdue installments of interest and overdue principal that has become due 
otherwise than by such declaration of acceleration have been paid, (iii) the 
rescission would not conflict with any judgment or decree of a court of 
competent jurisdiction and (iv) all payments due to the Trustee and any 
predecessor Trustee under Section 607 have been made.

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 of any 
series 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 of any series at the Maturity 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 or rates prescribed therefor in such Securities, and, in addition 
thereto, such further amount as shall be sufficient to cover the reasonable 
costs and expenses of collection, including the reasonable compensation, 
expenses, disbursements and advances of the Trustee, its agents and counsel.

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

    If an Event of Default with respect to Securities of any series occurs 
and is continuing, the Trustee may in its discretion proceed to protect and 
enforce its rights and the rights of the Holders of Securities of such series 
by such appropriate judicial proceedings as the Trustee shall deem most 
effectual to protect and enforce any such rights, whether for the specific 
enforcement 

                                       36



of any covenant or agreement in this Indenture or in aid of the exercise of 
any power granted herein, or to secure any other proper remedy.

SECTION 504.    Trustee May File Proofs of Claim.

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

         (i)  to file and prove a claim for the whole amount of principal (and
    premium, if any) and interest owing and unpaid in respect of the Securities
    and to file such other papers or documents as may be necessary or advisable
    in order to have the claims of the Trustee (including any claim for the
    reasonable compensation, expenses, disbursements and advances of the
    Trustee, its agent and counsel) and of the Holders allowed in such judicial
    proceedings, and
         
         (ii) to collect and receive any moneys or other property payable or
    deliverable on any such claims and to distribute the same; and any
    custodian, receiver, assignee, trustee, liquidator, sequestrator or other
    similar official in any such judicial proceeding is hereby authorized by
    each Holder 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.

    Nothing herein contained 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.

SECTION 505.    Trustee May Enforce Claims Without Possession of Securities.

    All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee with 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 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 in respect of which such judgment has been
recovered.

                                       37



SECTION 506.    Application of Money Collected.

    Any money collected by the Trustee pursuant to this Article in respect of
the Securities of any series 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 in respect of which moneys have been collected
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
applicable to such series;

    Second:  To the payment of the amounts then due and unpaid for principal of
(and premium, if any) and interest on the Securities of such series 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 of such series for principal (and premium, if any)
and interest, respectively; and

    Third:  To the Company.

    The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 506.  At least fifteen (15) days before such
record date, the Trustee shall mail to each Holder and the Company a notice that
states the record date, the payment date and the amount to be paid.

SECTION 507.    Limitation on Suits.

    No Holder of any Security of any series 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;

    (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

                                       38



    (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 Holders of Securities of
any series shall have any right in any manner whatever by virtue of, or by
availing himself 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 Holders of Securities of the affected series.

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 Section 307)
interest on such Security on the Stated Maturity or Maturities expressed in such
Security (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 with 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 has 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 Securities to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or 

                                       39



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 of any series shall have the right to direct the time, method and 
place of conducting any proceeding for any remedy available to the Trustee, 
or exercising any trust or power conferred on the Trustee, with respect to 
the Securities of such series, provided that:

    (1)  such direction shall not be in conflict with any rule of law or with
this Indenture;
    
    (2)  the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction; and
    
    (3)  subject to Section 601, the Trustee need not take any action which
might involve the Trustee in personal liability or be unduly prejudicial to the
Holders not joining therein.

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 by written notice to the Trustee on 
behalf of the Holders of all the Securities of such series waive any Default 
or Event of Default with respect to such series and its consequences, except 
a Default or Event of Default

    (1)  in respect of the payment of the principal of (or premium, if any) or
interest on any Security of such series, or
    
    (2)  in respect of a covenant or other provision hereof which under Article
Nine cannot be modified or amended with the consent of the Holder of each
Outstanding Security of such series affected.

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

SECTION 514.     Undertaking for Costs.

    All parties to this Indenture agree, and each Holder of any Security by 
his acceptance thereof shall be deemed to have agreed, that any court may in 
its discretion require, in any suit for the enforcement of any right or 
remedy under this Indenture, or in any suit against the Trustee for any 
action taken, suffered or omitted by it as Trustee, the filing by any party 
litigant in such 

                                       40



suit of an undertaking to pay the costs of such suit, and that such court may 
in its discretion assess reasonable costs, including reasonable attorneys' 
fees, against any party litigant in such suit, having due regard to the 
merits and good faith of the claims or defenses made by such party litigant; 
but the provisions of this Section shall not apply to any suit instituted by 
the Company, to any suit instituted by the Trustee, to any suit instituted by 
any Holder, or group of Holders, holding in the aggregate more than 10% in 
principal amount of the Outstanding Securities of any series, or to any suit 
instituted by any Holder for the enforcement of the payment of the principal 
of (or premium, if any) or interest on any Security on or after the Stated 
Maturity or Maturities expressed in such Security (or, in the case of 
redemption, on or after the Redemption Date).

                                  ARTICLE SIX
                                       
                                  THE TRUSTEE

SECTION 601.    Certain Duties and Responsibilities of the Trustee.

   (a)   Except during the continuance of an Event of Default, the Trustee's 
duties and responsibilities under this Indenture shall be governed by Section 
315(a) of the Trust Indenture Act.

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

   (c)   None of the provisions of Section 315(d) of the Trust Indenture Act
shall be excluded from this Indenture.

SECTION 602.    Notice of Defaults.

    Within 30 days after the occurrence of any Default or Event of Default 
with respect to the Securities of any series, the Trustee shall give to all 
Holders of Securities of such series, as their names and addresses appear in 
the Security Register, notice of such Default or Event of Default known to 
the Trustee, unless such Default or Event of Default shall have been cured or 
waived; provided, however, that, except in the case of a Default or Event of 
Default in the payment of the principal of (or premium, if any) or interest 
on any Security of such series or in the payment of any sinking fund 
installment with respect to Securities of such series, the Trustee shall be 
protected in withholding such notice if and so long as the board of 
directors, the executive committee or directors or Responsible Officers of 
the Trustee in good faith determine that the withholding of such notice is in 
the interest of the Holders of Securities of such series.

SECTION 603. Certain Rights of Trustee.

    Subject to the provisions of the Trust Indenture Act:

                                       41



    (a)  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;

    (b)  any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order and any resolution
of the Board of Directors may be sufficiently evidenced by a Board Resolution;

    (c)  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 Officer's Certificate;

    (d)  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;

    (e)  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 security or indemnity to its reasonable satisfaction against the
costs, expenses and liabilities which might be incurred by it in compliance with
such request or direction;

    (f)  prior to the occurrence of an Event of Default with respect to the
Securities of any series and after the curing or waiving of all such Events of
Default which may have occurred, 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, approval or other paper or document, or the books and records of the
Company, unless requested in writing to do so by the Holders of a majority in
principal amount of the Outstanding Securities of any series; provided, however,
that if the payment within a reasonable time to the Trustee of the costs,
expenses or liabilities likely to be incurred by it in the making of such
investigation is not, in the opinion of the Trustee, reasonably assured to the
Trustee by the security afforded to it by the terms of this Indenture, the
Trustee may require reasonable indemnity against such costs, expenses or
liabilities as a condition to so proceeding; the reasonable expense of every
such investigation shall be paid by the Company or, if paid by the Trustee,
shall be repaid by the Company upon demand;

    (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; and

    (h)  the Trustee shall not be required to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of 

                                       42



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.

SECTION 604.    Not Responsible for Recitals or Issuance of Securities.

    The recitals herein and in the Securities, 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.  Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.

SECTION 605.    May Hold Securities.

    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 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 in trust hereunder (including amounts held by the
Trustee as Paying Agent) 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 upon in writing
with the Company.

SECTION 607.    Compensation and Reimbursement.

    The Company agrees

         (1)  to pay to the Trustee from time to time reasonable compensation
    for all services rendered by 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 bad
    faith; and
         
         (3)  to indemnify the Trustee for, and to hold it harmless against,
    any loss, liability, damage, claim or expense, including taxes (other than
    taxes based upon or determined or measured by the income of the Trustee),
    incurred without gross negligence 

                                       43



    or bad faith on its part, arising  of or in connection with the acceptance 
    or administration of the trust or trusts hereunder, including the costs and
    expenses of defending itself against any claim or liability in connection 
    with the exercise or performance of any of its powers or duties hereunder.

    When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 501(5) or Section 501(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or
other similar law.

    The provisions of this Section 607 shall survive this Indenture.

SECTION 608.    Disqualification; Conflicting Interests.

    The Trustee shall be disqualified only where such disqualification is
required by Section 310(b) of the Trust Indenture Act.  Nothing shall prevent
the Trustee from filing with the Commission the application referred to in the
second to last paragraph of Section 310(b) of the Trust Indenture Act.

SECTION 609.    Corporate Trustee Required; Eligibility.

    There shall at all times be a Trustee hereunder which shall be eligible to
act as Trustee under Section 310(a)(1) of the Trust Indenture Act having a
combined capital and surplus of at least $50,000,000 subject to supervision or
examination by federal or State authority.  If such corporation 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 corporation shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published.  Neither the Company nor any Person directly or
indirectly controlling, controlled by, or under common control with the Company
may serve as Trustee.  If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

SECTION 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 in accordance with the
applicable requirements of Section 611.

    (b)  The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company.  If 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 

                                       44



of competent jurisdiction for the appointment of a successor Trustee with 
respect to the Securities of such series.

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

    (d)  If at any time:
         
         (1)  the Trustee shall fail to comply with Section 310(b) of the Trust
    Indenture Act 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 of a Security who has been a bona fide Holder of a Security
    for at least six months; 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 with respect to all Securities, or (ii) subject to Section 315(e) of the
Trust Indenture Act, 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.

    (e)  If the Trustee shall resign, be removed or become incapable of 
acting, or if a vacancy shall occur in the office of Trustee for any cause, 
with respect to the Securities of one or more series, the Company, by 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 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 with respect to such Securities.  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, 

                                       45



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.

    (f)  The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses appear in the
Security Register.  Each notice shall include the name of the successor Trustee
with respect to the Securities of such series and the address of its Corporate
Trust Office.

SECTION 611.     Acceptance of Appointment by Successor.

    (a)  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; 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, transfer and deliver to such 
successor Trustee all property and money held by such retiring Trustee 
hereunder.

    (b)  In case of the appointment hereunder of a successor Trustee with 
respect to the Securities of one or more (but not all) series, the Company, 
the retiring Trustee and each successor Trustee with respect to the 
Securities of one or more series shall execute and deliver an indenture 
supplemental hereto wherein each successor Trustee shall accept such 
appointment and which (1) shall contain such provisions as shall be necessary 
or desirable to transfer and confirm to, and to vest in, each successor 
Trustee all the rights, powers, trusts and duties of the retiring Trustee 
with respect to the Securities of that or those series to which the 
appointment of such successor Trustee relates, (2) if the retiring Trustee is 
not retiring with respect to all Securities, shall contain such provisions as 
shall be deemed necessary or desirable to confirm that all the rights, 
powers, trusts and duties of the retiring Trustee with respect to the 
Securities of that or those series as to which the retiring Trustee is not 
retiring shall continue to be vested in the retiring Trustee, and (3) shall 
add to or change any of the provisions of this Indenture as shall be 
necessary to provide for or facilitate the administration of the trusts 
hereunder by more than one Trustee, it being understood that nothing herein 
or in such supplemental indenture shall constitute such Trustees co-trustees 
of the same trust and that each such Trustee shall be trustee of a trust or 
trusts hereunder separate and apart from any trust or trusts hereunder 
administered by any other such Trustee; and upon the execution and delivery 
of such supplemental indenture the resignation or removal of the retiring 
Trustee shall become effective to the extent provided therein and each such 
successor Trustee, without any further act, deed or conveyance, shall become 
vested with all the rights, powers, trusts and duties of the retiring Trustee 
with respect to the Securities of that or those series to which the 
appointment of such successor Trustee relates; but, on request of the Company 
or any successor Trustee, such retiring Trustee shall duly assign, 

                                       46



transfer and deliver to such successor Trustee all property and money held by 
such retiring Trustee hereunder with respect to the Securities of that or 
those series to which the appointment of such successor Trustee relates.

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

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

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.

SECTION 613.     Preferential Collection of Claims Against Company.

    The Trustee shall comply with Section 311(a) of the Trust Indenture Act,
excluding any creditor relationship listed in Section 311(b) of the Trust
Indenture Act.  A Trustee who has resigned or been removed shall be subject to
Section 311(a) of the Trust Indenture Act to the extent indicated therein.

SECTION 614.     Appointment of Authenticating Agent.

    At any time when any of the Securities remain outstanding the Trustee may 
appoint an Authenticating Agent or Agents with respect to one or more series 
of Securities which shall be authorized to act on behalf of, and subject to 
the direction of, the Trustee to authenticate Securities of such series 
issued 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 

                                       47



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 mail 
written notice of such appointment by first-class mail, postage prepaid, to 
all Holders of Securities of the series with respect to which such 
Authenticating Agent will serve, as their names and addresses appear in the 
Security Register.  Any successor Authenticating Agent upon acceptance of its 
appointment hereunder shall become vested with all the rights, powers and 
duties of its predecessor hereunder, with like effect as if originally named 
as an Authenticating Agent. No successor Authenticating Agent shall be 
appointed unless eligible under the provisions of this Section.

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

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

         Form of Authenticating Agent's 
         Certificate of Authentication

                                       48

               HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

SECTION 701.    Company to Furnish Trustee Names and Addresses of Holders.

    The Company will furnish or cause to be furnished to the Trustee:

    (a)  semi-annually, not later than January 1 and July 1 in each year, a 
list, in such form as the Trustee may reasonably require, of the names and 
addresses of the Holders as of the preceding December 15 or June 15, as the 
case may be; and

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

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

SECTION 702.    Preservation of Information; Communications to Holders.

    (a)  The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 701 and the names and
addresses of Holders received by the Trustee in its capacity as Security
Registrar.  The Trustee may destroy any list furnished to it as provided in
Section 701 upon receipt of a new list so furnished.

    (b)  If three or more Holders (herein referred to as "applicants") apply in
writing to the Trustee, and furnish to the Trustee reasonable proof that each
such applicant has owned a Security for a period of at least six months
preceding the date of such application, and such application states that the
applicants desire to communicate with other Holders with respect to their rights
under this Indenture or under the Securities and is accompanied by a copy of the
form of proxy or other communication which such applicants propose to transmit,
then the Trustee shall, within five Business Days after the receipt of such
application, at its election, either

         (i)  afford such applicants access to the information preserved at the
    time by the Trustee in accordance with Section 702(a); or

         (ii) inform such applicants as to the approximate number of Holders
    whose names and addresses appear in the information preserved at the time
    by the Trustee in accordance with Section 702(a), and as to the approximate
    cost of mailing to such Holders the form of proxy or other communication,
    if any, specified in such application.

                                       50



    If the Trustee shall elect not to afford such applicants access to such 
information, the Trustee shall, upon the written request of such applicants, 
mail to each Holder whose name and address appears in the information 
preserved at the time by the Trustee in accordance with Section 702(a) a copy 
of the form of proxy or other communication which is specified in such 
request, with reasonable promptness after a tender to the Trustee of the 
material to be mailed and of payment, or provision for the payment, of the 
reasonable expenses of mailing, unless within five days after such tender the 
Trustee shall mail to such applicants and file with the Commission, together 
with a copy of the material to be mailed, a written statement to the effect 
that, in the opinion of the Trustee, such mailing would be contrary to the 
best interests of the Holders or would be in violation of applicable law.  
Such written statement shall specify the basis of such opinion.  If the 
Commission, after opportunity for a hearing upon the objections specified in 
the written statement so filed, shall enter an order refusing to sustain any 
of such objections or if, after the entry of an order sustaining one or more 
of such objections, the Commission shall find, after notice and opportunity 
for hearing, that all objections so sustained have been met and shall enter 
an order so declaring, the Trustee shall mail copies of such material to all 
such Holders with reasonable promptness after the entry of such order and the 
renewal of such tender; otherwise the Trustee shall be relieved of any 
obligation or duty to such applicants respecting their application.

    (c)  Every Holder of Securities, by receiving and holding the same, agrees
with the Company and the Trustee that neither the Company nor the Trustee nor
any agent of either of them shall be held accountable by reason of the
disclosure of any such information as to the names and addresses of the Holders
in accordance with Section 702(b), regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under Section 702(b).

SECTION 703.    Reports by Trustee.

    (a)  Within 60 days after May 15 of each year commencing with the year
1997, the Trustee shall transmit by mail to all Holders of Securities as
provided in Section 313(c) of the Trust Indenture Act, a brief report dated as
of May 15, if required by and in compliance with Section 313(a) of the Trust
Indenture Act.

    (b)  A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Trustee with each stock exchange upon which any
Securities are listed, with the Commission and with the Company.  The Company
will notify the Trustee when any Securities are listed on any stock exchange.

SECTION 704.    Reports by Company.

    The Company shall:

    (1)  file with the Trustee, within 30 days after the Company is required 
to file the same with the Commission, copies of the annual reports and of the 
information, documents and 

                                       51

Commission may from time to time by rules and regulations prescribe) which 
the Company may be required to file with the Commission pursuant to Section 
13 or Section 15(d) of the Exchange Act; or, if the Company is not required 
to file information, documents or reports pursuant to either of said 
Sections, then it shall file with the Trustee and the Commission, in 
accordance with rules and regulations prescribed from time to time by the 
Commission, such of the supplementary and periodic information, documents and 
reports which may be required pursuant to Section 13 of the Exchange Act in 
respect of a security listed and registered on a national securities exchange 
as may be prescribed from time to time in such rules and regulations;

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

    (3)  transmit by mail to all Holders, as their names and addresses appear 
in the Security Register, (a) concurrently with furnishing the same to its 
stockholders but only to the extent the Company is otherwise required to 
furnish an annual report to its stockholders, the Company's annual report to 
stockholders, containing certified financial statements, and any other 
financial reports which the Company generally furnishes to its stockholders, 
and (b) within 30 days after the filing thereof with the Trustee, such 
summaries of any other information, documents and reports required to be 
filed by the Company pursuant to paragraphs (1) and (2) of this Section as 
may be required by rules and regulations prescribed from time to time by the 
Commission; and

    (4)  furnish to the Trustee, on or before May 1 of each year, a brief 
certificate from the principal executive officer, principal financial officer 
or principal accounting officer as to his or her knowledge of the Company's 
compliance with all conditions and covenants under this Indenture.  For 
purposes of this paragraph, such compliance shall be determined without regard 
to any period of grace or requirement of notice provided under this 
Indenture.  Such certificate need not comply with Section 102.

unless:

                                       52



    (1)  either the Company shall be the continuing Person or the Person (if 
other than the Company) formed by such consolidation or with which or into 
which the Company is merged or the Person (or group of affiliated Persons) to 
which all or substantially all the properties and assets of the Company as an

supplemental hereto, executed and delivered to the Trustee, in form 
satisfactory to the Trustee, all the obligations of the Company under the 
Securities and this Indenture; and
    
    (2)  immediately before and after giving effect to such transaction or 
series of related transactions, no Event of Default, and no Default, shall

provided, however, that nothing construed in this Section 801 or elsewhere in 
this Indenture shall be deemed to restrict or prohibit the Company from 
consummating the transactions contemplated by the Merger Agreement dated 
April 28, 1995, as amended as of July 26, 1995 among the Company, Wisconsin 
Energy Corporation, Northern Power Wisconsin Corp. and WEC Sub Corp.

substantially all of the property and assets of the Company in accordance 
with Section 801, the successor corporation formed by such consolidation or 
into which the Company is merged or the successor corporation or affiliated 
group of corporations to which such lease, sale, assignment, or transfer is 
made shall succeed to, and be substituted for, and may exercise every right 
and power of, the Company under this Indenture with the same effect as if 
such successor corporation or corporations had been named as the Company 
herein, and thereafter, except in the case of a lease, the predecessor 
corporation or corporations shall be relieved of all obligations and 
covenants under this Indenture and the Securities and in the event of such 
conveyance or transfer, except in the case of a lease, any such predecessor 
corporation may be dissolved and liquidated.

SECTION 901.    Supplemental Indentures Without Consent of Holders.

    Without notice to or the consent of any Holders, the Company, when

satisfactory to the Trustee, for any of the following purposes:

    (1)  to evidence the succession of another corporation to the Company and
the assumption by any such successor of the covenants of the Company herein and
in the Securities; or
    
    (2)  to add to the covenants of the Company for the benefit of the Holders
of all or any series of Securities (and if such covenants are to be for the

    (3)  to add any additional Events of Default with respect to all or any
series of Securities; or

in bearer form, registrable or not registrable as to principal, and with or 
without interest coupons; or
    
    (5)  to change or eliminate any of the provisions of this Indenture,

such supplemental indenture which is entitled to the benefit of such provision;
or
    
    (6)  to secure the Securities; or
    
    (7)  to establish the form or terms of Securities of any series as

any of the provisions of this Indenture or of modifying in any manner the rights
of the Holders of Securities of such series under this Indenture; provided,
however, that no such supplemental indenture shall, with the consent of the
Holder of each Outstanding Security affected thereby,

         (1)  change the Stated Maturity of the principal of, or any
    installment of principal of or interest on, any Security, or reduce the
    principal amount thereof or the rate of interest thereon or any premium
    payable upon the redemption thereof or extend the time for payment thereof,
    or reduce the amount of the principal of an Original Issue Discount
    Security that would be due and payable upon a declaration of acceleration
    of the Maturity thereof pursuant to Section 502, or change any Place of
    Payment where, or the coin or currency in which, any Security or any
    premium or the interest thereon is payable, or impair the right to
    institute suit for the enforcement of any such payment on or after the
    Stated Maturity thereof (or, in the case of redemption, on or after the
    Redemption Date);
         
         (2)  reduce the percentage in principal amount of the Outstanding
    Securities of any series, the consent of whose Holders is required for any
    such supplemental indenture, or the consent of whose Holders is required
    for any waiver of compliance with certain provisions of this Indenture or
    Defaults or Events of Default hereunder and their consequences provided for
    in this Indenture; or
    
         (3)  change the redemption provisions (including Article Eleven)
    hereof in a manner adverse to such Holder; 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
    consent of the Holder of each Outstanding 

                                       55




    Security affected thereby; provided, however, that this clause shall not 
    be deemed to require the consent of any Holder with respect to changes in 
    the references to "the Trustee" and concomitant changes in this Section, 
    or the deletion of this proviso, in accordance with the requirements of 
    Sections 611(b) and 901(8).

A supplemental indenture which changes or eliminates any covenant or other 
provisions 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.

    The Trustee shall sign any supplemental indenture authorized pursuant to
this Article, subject to the last sentence of this Section 903.  In executing,
or accepting the additional trusts created by, any supplemental indenture
permitted by this Article or the modifications thereby of the trusts created by
this Indenture, the Trustee shall be entitled to receive, and (subject to
Section 601) shall be fully protected in relying upon, an Officer's Certificate
and an Opinion of Counsel stating that the execution of such supplemental
indenture is authorized or permitted by this indenture.  The Trustee may, but
shall not be obligated to, enter into any such supplemental indenture which
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

SECTION 904.    Effect of Supplemental Indentures.

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

SECTION 905.    Conformity with Trust Indenture Act.

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

SECTION 906.    Reference in Securities to Supplemental Indentures.

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

                                       56



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.   Payments of Securities.

    With respect to each series of Securities, the Company will duly and 
punctually pay the principal of (and premium, if any) and interest on such 
Securities in accordance with their terms and this Indenture, and will duly 
comply with all the other terms, agreements and conditions contained in, or 
made in the Indenture for the benefit of, the Securities of such series.

SECTION 1002.   Maintenance of Office or Agency.

    The Company will maintain an office or agency in each Place of Payment 
where Securities may be surrendered for registration of transfer or exchange 
or for presentation for payment, where notices and demands to or upon the 
Company in respect of the Securities and this Indenture may be served.  The 
Company will give prompt written notice to the Trustee of the location, and 
any change in 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 address of the Trustee as 
set forth in Section 105 hereof.

    The Company may also from time to time designate one or more other 
offices or agencies where the Securities may be presented or surrendered for 
any or all such purposes and may from time to time rescind such designations. 
The Company will give prompt written notice to the Trustee of any such 
designation or rescission and of any change in the location of any such other 
office or agency.

    Unless otherwise set forth in, or pursuant to, a Board Resolution or 
Indenture supplemental hereto with respect to a series of Securities, the 
Company hereby initially designates the office of Norwest Bank Minnesota, 
National Association, Sixth and Marquette, Minneapolis, Minnesota 54479-0069, 
as such office of the Company.

SECTION 1003.   Corporate Existence.

    Subject to Article 8 hereof, the Company will do or cause to be done all 
things necessary to preserve and keep in full force and effect its corporate 
existence and that of each of its Subsidiaries and the rights (charter and 
statutory) of the Company and its Subsidiaries; provided, however, that (a) 
the Company shall not be required to preserve any such right, license or 
franchise or the corporate existence of any of its Subsidiaries if the Board 
of Directors, or the board of directors of the Subsidiary concerned, as the 
case may be, shall determine that the 

                                       57



preservation thereof is no longer desirable in the conduct of the business of 
the Company or any of its Subsidiaries and that the loss thereof is not 
materially disadvantageous to the Holders, and (b) nothing herein contained 
shall prevent any Subsidiary of the Company from liquidating or dissolving, 
or merging into, or consolidating with the Company (provided that the Company 
shall be the continuing or surviving corporation) or with any one or more 
Subsidiaries if the Board of Directors or the board of directors of the 
Subsidiary concerned, as the case may be, shall so determine.  
Notwithstanding anything contained in this Section 1003 or elsewhere in this 
Indenture, the Company and its Subsidiaries shall be permitted to consummate 
the transactions contemplated by the Merger Agreement dated April 28, 1995, 
as amended as of July 26, 1995 among the Company, Wisconsin Energy 
Corporation, Northern Power Wisconsin Corp. and WEC Sub Corp.

SECTION 1004.   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 material taxes, assessments 
and governmental charges levied or imposed upon the Company or any Subsidiary 
or upon the income, profits or property of the Company or any Subsidiary, and 
(2) all lawful claims for labor, materials and supplies which, if unpaid, 
might by law become a material lien upon the property of the Company or any 
Subsidiary; provided, however, that the Company shall not be required to pay 
or discharge or cause to be paid or discharged any such tax, assessment, 
charge or claim whose amount, applicability or validity is being contested in 
good faith by appropriate proceedings and for which adequate provision has 
been made.

SECTION 1005.   Maintenance of Properties.

    The Company will cause all material properties used or useful in the 
conduct of its business or the business of any of its Subsidiaries to be 
maintained and kept in good condition, repair and working order (normal wear 
and tear excepted) and supplied with all necessary equipment and will cause 
to be made all necessary repairs, renewals, replacements, betterments and 
improvements thereof, all as in the judgment of the Company may be necessary, 
so that the business carried on in connection therewith may be properly and 
advantageously conducted at all times; provided, however, that nothing in 
this Section shall prevent the Company from discontinuing the operation or 
maintenance of any of such properties, or disposing of any of them, if such 
discontinuance or disposal is, in the judgment of the Board of Directors or 
of the board of directors of the Subsidiary concerned, as the case may be, 
desirable in the conduct of the business of the Company or any Subsidiary of 
the Company and not materially disadvantageous to the Holders.

SECTION 1006.   Compliance Certificates.

    (a)   The Company shall deliver to the Trustee within 90 days after the end
of each fiscal year of the Company (which fiscal year currently ends on December
31), an Officer's Certificate stating whether or not the signer knows of any
Default or Event of Default by the Company that occurred prior to the end of the
fiscal year and is then continuing.  If the signer 

                                       58



does know of such a Default or Event of Default, the certificate shall 
describe each such Default or Event of Default and its status and the 
specific section or sections of this Indenture in connection with which such 
Default or Event of Default has occurred.  The Company shall also promptly 
notify the Trustee in writing should the Company's fiscal year be changed so 
that the end thereof is on any date other than the date on which the 
Company's fiscal year currently ends.  The certificate need not comply with 
Section 102 hereof.

    (b)  The Company shall deliver to the Trustee, within 10 days after the 
occurrence thereof, notice of any acceleration which with the giving of 
notice and the lapse of time would be an Event of Default within the meaning 
of Section 501(4) hereof.

    (c)  The Company shall deliver to the Trustee forthwith upon becoming aware
of a Default or Event of Default (but in no event later than 10 days after the
occurrence of each Default or Event of Default that is continuing), an Officer's
Certificate setting forth the details of such Default or Event of Default and
the action that the Company proposes to take with respect thereto and the
specific section or sections of this Indenture in connection with which such
Default or Event of Default has occurred.

SECTION 1007.   Commission Reports.

    (a)  The Company shall file with the Trustee, within 30 days after it files
them with the Commission, copies of the quarterly and annual reports and of the
information, documents, and other reports (or copies of such portions of any of
the foregoing as the Commission may by rules and regulations prescribe) which
the Company is required to file with the Commission pursuant to Section 13 or
15(d) of the Exchange Act.  If the Company is not subject to the requirement of
such Section 13 or 15(d) of the Exchange Act, the Company shall file with the
Trustee, within 30 days after it would have been required to file such
information with the Commission, financial statements, including any notes
thereto and, with respect to annual reports, an auditors' report by an
accounting firm of established national reputation and a "Management's
Discussion and Analysis of Financial Condition and Results of Operations," both
comparable to that which the Company would have been required to include in such
annual reports, information, documents or other reports if the Company had been
subject to the requirements of such Sections 13 or 15(d) of the Exchange Act. 
The Company also shall comply with the other provisions of Section 314(a) of the
Trust Indenture Act.

    (b)  So long as the Securities remain outstanding, the Company shall cause 
its annual report to stockholders and any other financial reports furnished 
by it to stockholders generally, to be mailed to the Holders at their 
addresses appearing in the register of Securities maintained by the Security 
Registrar in each case at the time of such mailing or furnishing to 
stockholders.  If the Company is not required to furnish annual or quarterly 
reports to its stockholders pursuant to the Exchange Act, the Company shall 
cause its financial statements, including any notes thereto and, with respect 
to annual reports, an auditors' report by an accounting firm of established 
national reputation and a "Management's Discussion and Analysis of Financial 
Condition and Results of Operations," to be so filed with the Trustee and 
mailed to the Holders within 90 days 

                                       59



after the end of each of the Company's fiscal years and within 45 days after 
the end of each of the first three quarters of each fiscal year.

    (c)  The Company shall provide the Trustee with a sufficient number of
copies of all reports and other documents and information that the Company may
be required to deliver to the Holders under this Section 1007.

SECTION 1008.   Waiver of Stay, Extension or Usury 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, and will actively resist any and all efforts to be compelled to take 
the benefit or advantage of, any stay or extension law or any usury law or 
other law, which would prohibit or forgive the Company from paying all or any 
portion of the principal of and/or interest on the Securities as contemplated 
herein, wherever enacted, now or at any time hereafter in force, or which may 
affect the covenants or the performance of this Indenture; and (to the extent 
that it may lawfully do so) the Company hereby expressly waives all benefit 
or advantage of any such law, and covenants that it will not hinder, delay or 
impede the execution of any power herein granted to the Trustee, but will 
suffer and permit the execution of every such power as though no such law had 
been enacted.

SECTION 1009.   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 (and premium, if any) 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 premium, if any) 
or 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, it will, prior to each due date of the principal of (and 
premium, if any) or interest on any Securities of that series, deposit with a 
Paying Agent a sum sufficient to pay the principal (and premium, if any) or 
interest so becoming due, such sum to be held in trust for the benefit of the 
Persons entitled to such principal, premium or interest, and (unless such 
Paying Agent is the Trustee) the Company will promptly notify the Trustee of 
its action or failure to so 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)  hold all sums held by it for the payment of the principal of (and
    premium, if any) or interest on Securities of that series in trust for the
    benefit of the Persons entitled thereto until such sums shall be paid to
    such Persons or otherwise disposed of as herein provided;

                                       60


         
         (2)  give the Trustee notice of any default by the Company (or any
    other obligor upon the Securities of that series) in the making of any
    payment of principal (and premium, if any) or interest on the Securities of
    that series; and
         
         (3)  at any time during the continuance of any such default, upon the
    written request of the Trustee, forthwith pay to the Trustee all sums so
    held in trust by such Paying Agent.

    The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same 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 (and premium, if 
any) or interest on any Security of any series and remaining unclaimed for 
two years after such principal (and premium, if any) or interest has become 
due and payable shall be paid to the Company on Company Request, or (if then 
held by the Company) shall be discharged from such trust; and the Holder of 
such Security 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 of such Paying Agent, before being required to make any such 
repayment, may at the expense of the Company cause to be published once, in a 
newspaper published in the English language, customarily published on each 
Business Day and of general circulation in New York, New York, notice that 
such money remains unclaimed and that, after a date specified therein, which 
shall not be less than 30 days from the date of such publication, any 
unclaimed balance of such money then remaining will be repaid to the Company.

                                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.

                                       61



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 and of the principal amount of Securities of such series 
to be redeemed.  In the case of any redemption of Securities prior to the 
expiration of any restriction on such redemption provided in the terms of 
such Securities or elsewhere in this Indenture, the Company shall furnish the 
Trustee with an Officer's 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, the 
particular Securities to be redeemed shall be selected not more than 90 days 
prior to the Redemption Date by the Trustee, from the Outstanding Securities of 
such series not previously called for redemption, substantially pro rata, by 
lot or by any other method as the Trustee considers fair and appropriate and 
that complies with the requirements of the principal national securities 
exchange, if any, on which such Securities are listed, and which may provide 
for the selection for redemption of portions (equal to the minimum authorized 
denomination for Securities of that series or any integral multiple thereof) 
of the principal amount of Securities of such series of a denomination larger 
than the minimum authorized denomination for Securities of that series; 
provided that in case the Securities of such series have different terms and 
maturities, the Securities to be redeemed shall be selected by the Company 
and the Company shall give notice thereof to the Trustee.

    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 the 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 by first-class mail, postage prepaid,
mailed not less than 30 nor more than 45 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register.

    All notices of redemption shall state:

    (1)  the Redemption Date;

                                       62



    (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, 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 are to be surrendered for
payment of the Redemption Price;

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

    (7)  the CUSIP number, if any, of the Securities to be redeemed; and

    (8)  unless otherwise provided as to a particular series of Securities, if
at the time of publication or mailing of any notice of redemption the Company
shall not have deposited with the Trustee or Paying Agent and/or irrevocably
directed the Trustee or Paying Agent to apply, from money held by it available
to be used for the redemption of Securities, an amount in cash sufficient to
redeem all of the Securities called for redemption, including accrued interest
to the Redemption Date, such notice shall state that it is subject to the
receipt of the redemption moneys by the Trustee or Paying Agent before the
Redemption Date (unless such redemption is mandatory) and such notice shall be
of no effect unless such moneys are so received before such date.

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

SECTION 1105.   Deposit of Redemption Price.

    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 1009) 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 

                                       63



Redemption Price and accrued interest) such Securities shall cease to bear 
interest.  Upon surrender of any such Security for redemption in accordance 
with said notice, such Security shall be paid by the Company at the 
Redemption Price, together with accrued interest to the Redemption Date; 
provided, however, that 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 Regular or Special Record Dates according 
to their terms and the provisions of Section 307.

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

SECTION 1107.   Securities Redeemed in Part.

    Any Security which is to be redeemed only in part shall be surrendered at 
an office or agency of the Company 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 Security with service charge, a new 
Security or Securities of the same series and Stated Maturity, 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.

                                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.

                                       64



SECTION 1202.   Satisfaction of Sinking Fund Payments with Securities.

    The Company (1) may deliver Securities of a series (other than any 
Securities previously called for redemption) 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 satisfaction 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 45 days prior to each sinking fund payment date for any 
series of Securities, the Company will deliver to the Trustee an Officer's 
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, 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

                      DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1301.   Applicability of Article; Company's Option to Effect Defeasance
                or Covenant Defeasance.

    Unless pursuant to Section 301 provision is made for the inapplicability 
of either or both of (a) Defeasance of the Securities of a series under 
Section 1302 or (b) Covenant Defeasance of the Securities of a series under 
Section 1303, then the provisions of such Section or Sections, as the case 
may be, together with the other provisions of this Article, shall be 
applicable to the Securities of such series, and the Company may at its 
option by Board Resolution, at any time, with respect to the Securities of 
such series, elect to have either Section 1302 (unless inapplicable) or 
Section 1303 (unless inapplicable) be applied to the Outstanding Securities of 
such series upon compliance with the applicable conditions set forth below in 
this Article.

                                       65



SECTION 1302.   Defeasance and Discharge.

    Upon the Company's exercise of the option provided in Section 1301 to 
defease the Outstanding Securities of a particular series, the Company shall be 
discharged from its obligations with respect to the Outstanding Securities of 
such series on the date the applicable conditions set forth in Section 1304 
are satisfied (hereinafter, "Defeasance").  Defeasance shall mean that the 
Company shall be deemed to have paid and discharged the entire indebtedness 
represented by the Outstanding Securities of such series and to have satisfied 
all its other obligations under such Securities and this Indenture insofar as 
such Securities are concerned (and the Trustee, at the expense of the 
Company, shall execute proper instruments acknowledging the same); provided, 
however, that the following rights, obligations, powers, trusts, duties and 
immunities shall survive until otherwise terminated or discharged hereunder: 
(A) the rights of Holders of Outstanding Securities of such series to receive, 
solely from the trust fund provided for in Section 1304, payments in respect 
of the principal of (and premium, if any) and interest on such Securities 
when such payments are due, (B) the Company's obligations with respect to 
such Securities under Sections 304, 305, 306, 1002 and 1009, (C) the rights, 
powers, trusts, duties and immunities of the Trustee hereunder and (D) this 
Article.  Subject to compliance with this Article, the Company may exercise 
its option with respect to Defeasance under this Section 1302 notwithstanding 
the prior exercise of its option with respect to Covenant Defeasance under 
Section 1303 in regard to the Securities of such series.

SECTION 1303.   Covenant Defeasance.

    Upon the Company's exercise of the option provided in Section 1301 to 
obtain a Covenant Defeasance with respect to the Outstanding Securities of a 
particular series, the Company shall be released from its obligations under 
this Indenture (except its obligations under Sections 304, 305, 306, 506, 
509, 610, 1001, 1002, 1006, 1008 and 1009) with respect to the Outstanding 
Securities of such series on and after the date the applicable conditions set 
forth in Section 1304 are satisfied (hereinafter, "Covenant Defeasance").  
Covenant Defeasance shall mean that, with respect to the Outstanding Securities 
of such series, the Company may omit to comply with and shall have no 
liability in respect of any term, condition or limitation set forth in this 
Indenture (except its obligations under Sections 304, 305, 306, 506, 509, 
610, 1001, 1002, 1006, 1008 and 1009), whether directly or indirectly by 
reason of any reference elsewhere herein or by reason of any reference to any 
other provision herein or in any other document, and such omission to comply 
shall not constitute an Event of Default under Section 501(4) with respect to 
Outstanding Securities of such series, and the remainder of this Indenture and 
of the Securities of such series shall be unaffected thereby.

SECTION 1304.   Conditions to Defeasance or Covenant Defeasance.

609 who shall agree to comply with the

provisions of this Article applicable to it), under the terms of an 
irrevocable trust agreement in form and substance reasonably satisfactory to 
such Trustee, as trust funds in trust for the purpose of making the following 
payments, specifically pledged as security for, and dedicated solely to, the 
benefit of the Holders of such Securities, (A) Dollars in an amount, or (B) 
U.S. Government Obligations which through the scheduled payment of principal 
and interest in respect thereof in accordance with their terms will provide, 
not later than the due date of any payment, money in an amount, or (C) a 
combination thereof, in each case sufficient, after payment of all federal, 
state and local taxes or other charges or assessments in respect thereof 
payable by the Trustee, in the opinion of a nationally recognized firm of 
independent public accountants expressed in a written certification thereof 
delivered to the Trustee, to pay and discharge, and which shall be applied by 
the Trustee (or other qualifying trustee) to pay and discharge, (i) the 
principal of (and premium, if any, on) and each installment of principal of 
(and premium, if any) and interest on the Outstanding Securities of such 
series on the Stated Maturity of such principal or installment of principal 
or interest and (ii) any mandatory sinking fund payments or analogous 
payments applicable to the Outstanding Securities of such series on the day 
on which such payments are due and payable in accordance with the terms of 
this Indenture and of such Securities.
    
         (2)  No Default or Event of Default with respect to the Securities of
    such series shall have occurred and be continuing on the date of such

    continuing, at any time during the period ending on the 91st day after the
    date of such deposit (it being understood that this condition shall not be
    deemed satisfied until the expiration of such period).
    
         (3)  Such deposit, 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.
    
         (4)  Such Defeasance or Covenant Defeasance shall not cause any
    Securities of such series then listed on any national securities exchange
    registered under the Exchange Act to be delisted.
    
         (5)  In the case of an election with respect to Section 1302, the
    Company shall have delivered to the Trustee either (A) a ruling directed to
    the Trustee received from the Internal Revenue Service to the effect that
    the Holders of the Outstanding Securities of such series will not recognize
    income, gain or loss for federal income tax purposes as a result of such
    Defeasance and will be subject to federal income tax on the same amounts,
    in the same manner and at the same times as would have been the case if
    such Defeasance had not occurred or (B) an Opinion of Counsel, based on
    such ruling or on a change in the applicable federal income tax law since
    the date of this Indenture, in either case to the effect that, and based
    thereon such opinion shall confirm that, the Holders of the Outstanding
    Securities of such series will not recognize income, gain or loss for
    federal income tax purposes as a result of such Defeasance and will be
    subject to federal income tax on the same amounts, in the same manner and
    at the same times as would have been the case if such Defeasance had not
    occurred.

                                       67


    
         (6)  In the case of an election with respect to Section 1303, the
    Company shall have delivered to the Trustee an Opinion of Counsel or a
    ruling directed to the Trustee received from the Internal Revenue Service
    to the effect that the Holders of the Outstanding Securities of such series
    will not recognize income, gain or loss for federal income tax purposes as
    a result of such Covenant Defeasance and will be subject to federal income
    tax on the same amounts, in the same manner and at the same times as would
    have been the case if such Covenant Defeasance had not occurred.
    
         (7)  Such Defeasance or Covenant Defeasance shall be effected in
    compliance with any additional terms, conditions or limitations which may
    be imposed on the Company in connection therewith pursuant to Section 301.
         
         (8)  The Company shall have delivered to the Trustee an Officer's
    Certificate and an Opinion of Counsel, each stating that all conditions
    precedent provided for relating to either the Defeasance under Section 1302
    or the Covenant Defeasance under Section 1303 (as the case may be) have
    been complied with.

SECTION 1305.   Deposited Money and Government Obligations To Be Held In Trust.

    Subject to the provisions of the last paragraph of Section 1009, all 
money and Government Obligations (including the proceeds thereof) deposited 
with the Trustee (or other qualifying trustee--collectively for purposes of 
this Section 1305, the "Trustee") pursuant to Section 1304 in respect of the 
Outstanding Securities of a particular series 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 
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 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 which by law is 
for the account of the Holders of the Outstanding Securities of such series.

    Anything in this Article to the contrary notwithstanding, the Trustee 
shall deliver to and pay to the Company from time to time upon Company 
Request any money or Government Obligations held by it as provided in Section 
1304 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 for the purpose for which such money or Government 
Obligations were deposited.

                                SUBORDINATION

SECTION 1401.   Agreement of Securityholders that Securities Subordinated to
                Extent Provided.

    The Company, for itself, its successors and assigns, covenants and agrees
and each Holder of the Securities by his acceptance thereof likewise covenants
and agrees that the payment of the principal of, premium, if any, and interest
on each and all of the Securities is hereby expressly subordinated, to the
extent and in the manner hereinafter set forth, to the prior payment in full of
all Senior Indebtedness.  The provisions of this Article shall constitute a
continuing offer to all persons who, in reliance upon such provisions, become
holders of, or continue to hold, Senior Indebtedness, and such provisions are
made for the benefit of the holders of Senior Indebtedness, and such holders are
hereby made obligees hereunder the same as if their names were written herein as
such, and they and/or each of them may proceed to enforce such provisions.

SECTION 1402.   Company not to Make Payments with Respect to Securities in
                Certain Circumstances.

    (a)  Upon the maturity of any Senior Indebtedness by lapse of time, 
acceleration or otherwise, all principal thereof and premium, if any, and 
interest thereon shall first be paid in full, or such payment duly provided 
for in cash or in a manner satisfactory to the holder or holders of such 
Senior Indebtedness, before any payment is made on account of the principal 
of or premium, if any, or interest on the Securities or to acquire any of the 
Securities or on account of any sinking fund (except sinking fund payments 
made in Securities acquired by the Company before the maturity of such Senior 
Indebtedness).

    (b)  Upon the happening of (i) an event of default with respect to any 
Senior Indebtedness, as such event of default is defined therein or in the 
instrument under which it is outstanding, permitting the holders to accelerate 
the maturity thereof, or (ii) an event which, with the giving of notice, or 
lapse of time, or both, would constitute such an event of default, then, 
unless and until such event shall have been cured or waived or shall have 
ceased to exist, no payment shall be made by the Company with respect to the 
principal of or premium, if any, or interest on the Securities or to acquire 
any of the Securities or on account of any sinking fund for the Securities 
(except sinking fund payments made in Securities acquired by the Company 
before such default and notice thereof).

    (c)  In the event that notwithstanding the provisions of this Section 
1402 the Company shall make any payment to the Trustee on account of the 
principal of or premium, if any, or interest on the Securities, or on account 
of any sinking fund, or the Holders of the Securities shall receive any such 
payment, after the happening of a default in payment of the principal of or 
premium, if any, or interest on Senior Indebtedness, then, unless and until 
such default or event of default shall have been cured or waived or shall 
have ceased to exist, such payment (subject to 

                                       69



the provisions of Section 1406) shall be held by the Trustee or the Holders 
of the Securities, as the case may be, in trust for the benefit of, and shall 
be paid forthwith over and delivered to, the holders of Senior Indebtedness 
(pro rata as to each of such holders on the basis of the respective amounts 
of Senior Indebtedness held by them) or their representative or the trustee 
under the indenture or other agreement (if any) pursuant to which any 
instruments evidencing any Senior Indebtedness may have been issued, as their 
respective interests may appear, for application to the payment of all Senior 
Indebtedness remaining unpaid to the extent necessary to pay all Senior 
Indebtedness in full in accordance with the terms of such Senior 
Indebtedness, after giving effect to any concurrent payment or distribution 
to or for the holders of Senior Indebtedness.  The Company shall give prompt 
written notice to the Trustee of any default under any Senior Indebtedness or 
under any agreement pursuant to which Senior Indebtedness may have been 
issued.  

SECTION 1403.   Securities Subordinated to Prior Payment of all Senior
                Indebtedness on Dissolution, Liquidation or Reorganization of 
                Company.

    Upon any distribution of assets of the Company upon any dissolution,
winding up, liquidation or reorganization of the Company (whether in bankruptcy,
insolvency or receivership proceedings or upon an assignment for the benefit of
creditors or otherwise):

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

    (b)  any payment or distribution of assets of the Company of any kind or 
character, whether in cash, property or securities, to which the Holders of 
the Securities or the Trustees would be entitled except for the provisions of 
this Article Fourteen, shall be paid by the liquidating trustee or agent or 
other person making such payment or distribution, whether a trustee in 
bankruptcy, a receiver or liquidating trustee or other trustee or agent, 
directly to the holders of Senior Indebtedness or their representative or 
representatives, or to the trustee or trustees under any indenture under 
which any instruments evidencing any of such Senior Indebtedness may have 
been issued, to the extent necessary to make payment in full of all Senior 
Indebtedness remaining unpaid, after giving effect to any concurrent payment 
or distribution or provision therefor to the holders of such Senior 
Indebtedness;
    
    (c)  in the event that notwithstanding the foregoing provisions of this 
Section 1403, any payment or distribution of assets of the Company of any 
kind or character, whether in cash, property or securities, shall be received 
by the Trustee or the Holders of the Securities on account of principal, 
premium, if any, or interest on the Securities before all Senior Indebtedness 
is paid in full, or effective provision made for its payment, such payment or 
distribution (subject to the provisions of Section 1406 and 1407) shall be 
received and held in trust for and shall be paid over to the holders of the 
Senior Indebtedness remaining unpaid or unprovided for or their 
representative or representatives, or to the trustee or trustees under any 
indenture under which any instruments evidencing any of such Senior 
Indebtedness may have been issued, for 

                                       70



application to the payment of such Senior Indebtedness until all such Senior 
Indebtedness shall have been paid in full, after giving effect to any 
concurrent payment or distribution or provision therefor to the holders of 
such Senior Indebtedness.  

SECTION 1404.   Securityholders to be Subrogated to Right of Holders of Senior
                Indebtedness.

    Subject to the payment in full of all Senior Indebtedness, the Holders of 
the Securities shall be subrogated to the rights of the holders of Senior 
Indebtedness to receive payments or distributions of assets of the Company 
applicable to the Senior Indebtedness until all amounts owing on the 
Securities shall be paid in full, and for the purpose of such subrogation no 
payments or distributions to the holders of the Senior Indebtedness by or on 
behalf of the Company or by or on behalf of the Holders of the Securities by 
virtue of this Article which otherwise would have been made to the Holders of 
the Securities shall, as between the Company and the Holders of the 
Securities, be deemed to be payment by the Company to or on account of the 
Senior Indebtedness, it being understood that the provisions of this Article 
Fourteen are and are intended solely for the purpose of defining the relative 
rights of the Holders of the Securities, on the one hand, and the holders of 
the Senior Indebtedness, on the other hand.  

SECTION 1405.   Obligation of the Company Unconditional.

    Nothing contained in this Article Fourteen or elsewhere in this Indenture 
or in the Securities is intended to or shall impair as between the Company 
and the Holders of the Securities, the obligation of the Company, which is 
absolute and unconditional, to pay to the Holders of the Securities the 
principal of, premium, if any, and interest on the Securities as and when the 
same shall become due and payable in accordance with their terms, or is 
intended to or shall affect the relative rights of the Holders of the 
Securities and creditors of the Company other than the holders of the Senior 
Indebtedness, nor shall anything herein or therein prevent the Trustee or the 
Holder of any Security from exercising all remedies otherwise permitted by 
applicable law upon default under this Indenture, subject to the rights, if 
any, under this Article Fourteen of the holders of Senior Indebtedness in 
respect of cash, property, or securities of the Company received upon the 
exercise of any such remedy.  Upon any distribution of assets of the Company 
referred to in this Article Fourteen, the Trustee, subject to the provisions 
of Section 601, and the Holders of the Securities shall be entitled to rely 
upon any order or decree made by any court of competent jurisdiction in which 
such dissolution, winding up, liquidation or reorganization proceedings are 
pending, or a certificate of the liquidating trustee or agent or other person 
making any distribution to the Trustee or to the Holders of the Securities, 
for the purpose of ascertaining the persons entitled to participate in such 
distribution, the holders of the Senior Indebtedness and other indebtedness 
of the Company, the amount thereof or payable thereon, the amount or amounts 
paid or distributed thereon and all other facts pertinent thereto or to this 
Article Fourteen.  

SECTION 1406.   Trustee Entitled to Assume Payments Not Prohibited in Absence of
                Notice.

    The Trustee shall not at any time be charged with knowledge of the 
existence of any facts which would prohibit the making of any payment of 
monies to or by the Trustee, unless and until 

                                       71



a Responsible Officer of the Trustee shall have received written notice 
thereof from the Company or from one or more holders of Senior Indebtedness 
or from any trustee therefor; and, prior to the receipt of any such written 
notice, the Trustee, subject to the provisions of Section 601, shall be 
entitled to assume conclusively that no such facts exist. 

SECTION 1407.   Application by Trustee of Monies Deposited With It. 

    Anything in this Indenture to the contrary notwithstanding, any deposit 
of monies by the Company with the Trustee or any paying agent (whether or not 
in trust) for the payment of the principal of or premium, if any, or interest 
on any Securities shall be subject to the provisions of Sections 1401, 1402, 
1403 and 1404 except that, if prior to the date on which by the terms of this 
Indenture any such monies may become payable for any purpose (including, 
without limitation, the payment of either the principal of or the interest or 
premium, if any, on any Security) a Responsible Officer of the Trustee shall 
not have received with respect to such monies the notice provided for in 
Section 1406, then, anything herein contained to the contrary 
notwithstanding, the Trustee shall have full power and authority to receive 
such monies and to apply the same to the purpose for which they were 
received, and shall not be affected by any notice to the contrary which may 
be received by it on or after such date.  

SECTION 1408.   Subordination Rights not Impaired by Acts or Omissions of 
                Company or Holders of Senior Indebtedness.  

    No right of any present or future holders of any Senior Indebtedness to 
enforce subordination as herein provided shall at any time in any way be 
prejudiced or impaired by any act or failure to act on the part of the 
Company or by any act or failure to act, in good faith, by any such holder, 
or by any noncompliance by the Company with the terms, provisions and 
covenants of this Indenture, regardless of any knowledge thereof which any 
such holder may have or be otherwise charged with.  

SECTION 1409.   Securityholders Authorize Trustee to Effectuate Subordination 
                of Securities.

    Each Holder of the Securities by his acceptance thereof authorizes and 
expressly directs the Trustee on his behalf to take such action as may be 
necessary or appropriate to effectuate the subordination provided in this 
Article Fourteen and appoints the Trustee his attorney-in-fact for such 
purpose, including, in the event of any dissolution, winding up, liquidation 
or reorganization of the Company (whether in bankruptcy, insolvency or 
receivership proceedings or upon an assignment for the benefit of creditors 
or otherwise) tending towards liquidation of the business and assets of the 
Company, the immediate filing of a claim for the unpaid balance of its or his 
Securities in the form required in said proceedings and cause said claim to 
be approved.  If the Trustee does not file a proper claim or proof of debt in 
the form required in such proceeding prior to 30 days before the expiration 
of the time to file such claim or claims, then the holder or holders of 
Senior Indebtedness are hereby authorized to and have the right to file an 
appropriate claim for and on behalf of the holders of said Securities.  

                                       72



SECTION 1410.    Right of Trustee to Hold Senior Indebtedness.  

    The Trustee shall be entitled to all of the rights set forth in this 
Article Fourteen in respect of any Senior Indebtedness at any time held by it 
to the same extent as any other holder of Senior Indebtedness, and nothing in 
Section 613 or elsewhere in this Indenture shall be construed to deprive the 
Trustee of any of its rights as such holder.  

SECTION 1411.    Article Fourteen Not to Prevent Events of Default.  

    The failure to make a payment on account of principal, interest or 
sinking fund by reason of any provision in this Article Fourteen shall not be 
construed as preventing the occurrence of an Event of Default under Section 
501.  

                                ARTICLE FIFTEEN
                                       
                                 MISCELLANEOUS

SECTION 1501.   Miscellaneous.  

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

                                       73
