establishment) or established in one or more indentures supplemental hereto,

     conditions upon which, such election may be made;

          (13)  if the amount of payments of the principal of and interest on

     applicable to the offer, sale or delivery of Unregistered Securities or the

          (15)  if the Securities of such series are to be issuable in
     definitive form (whether upon original issue or upon exchange of a
     temporary Security of such series) only upon receipt of certain
     certificates or other documents or satisfaction of other conditions, the
     form and terms of such certificates, documents or conditions;

     covenants with respect to the Securities of such series;


                                   -12-




          (18)  with respect to Unregistered Securities, the countries, cities
     and/or newspaper or newspapers in such countries or cities in which notices
     required pursuant to Sections 5.11, 6.8, 6.10(a), 6.11, 8.2, 10.4, 11.4,
     12.2 and 12.5 are to be published (and unless otherwise specified in such
     Board Resolution or supplemental indenture or any Officers' Certificate
     delivered pursuant thereto, such newspaper will, if practicable, be (a) in
     the case of The City of New York, The Wall Street Journal (Eastern
     Edition), (b) in the case of the United Kingdom, The Financial Times
     (London Edition) and (c) in the case of Luxembourg, The Luxemburger Wort);
     and

          (19) any other terms of such series (which terms shall not adversely
     affect the interests of any Holders of Securities then Outstanding).

     All Securities of any one series and Coupons, if any, appertaining 
thereto shall be substantially identical, except in the case of Registered 
Securities as to denomination and except as may otherwise be provided by or 
pursuant to the Board Resolution or Officers' Certificate referred to above 
or as set forth in any indenture supplemental hereto referred to above.  All 
Securities of any one series need not be issued at the same time and may be 
issued from time to time, consistent with the terms of this Indenture, if so 
provided by or pursuant to such Board Resolution, such Officers' Certificate 
or in any such indenture supplemental hereto.

     SECTION 2.4 AUTHENTICATION AND DELIVERY OF SECURITIES.  The Issuer may 
from time to time deliver Securities of any series, having attached thereto 
appropriate Coupons, if any, executed by the Issuer to the Trustee for 
authentication, together with the applicable documents referred to below in 
this Section, and the Trustee shall thereupon authenticate and deliver such 
Securities to or upon the order of the Issuer (contained in the Issuer Order 
referred to below in this Section) or pursuant to such procedures acceptable 
to the Trustee and to such recipients as may be specified from time to time 
by an Issuer Order.  If so provided in or pursuant to the Board Resolution or 
supplemental indenture establishing the Securities of any series, the 
maturity date, original issue date, interest rate and any other terms of any 
or all of the Securities of such series and the Coupons, if any, appertaining 
thereto may be determined by or pursuant to such Issuer Order and procedures. 
 If provided for in such procedures, such Issuer Order may authorize 
authentication and delivery pursuant to oral or electronic instructions from 
the Issuer or its duly authorized agent, which instructions shall be promptly 
confirmed in writing.  In authenticating such Securities and accepting the 
additional responsibilities under this Indenture in relation to such 
Securities, the Trustee shall be entitled to receive (but, in the case of 
subparagraphs 2, 3 and 4 below, only 


                                   -13-



at or before the time of the first request of the Issuer to the Trustee to 
authenticate Securities of such series) and (subject to Section 6.1) shall be 
fully protected in relying upon, unless and until such documents have been 
superseded or revoked:

          (1)  an Issuer Order requesting such authentication and setting forth
     delivery instructions if the securities and the Coupons, if any, are not to
     be delivered to the Issuer, provided that, with respect to Securities of a
     series subject to a Periodic Offering, (a) such Issuer Order may be
     delivered by the Issuer to the Trustee at any time prior to the delivery to
     the Trustee of the Securities of such series for authentication and
     delivery, (b) the Trustee shall authenticate and deliver the Securities of
     such series for original issue from time to time, in an aggregate principal
     amount not exceeding the aggregate principal amount established for such
     series, pursuant to an Issuer Order or pursuant to such procedures
     acceptable to the Trustee as may be specified from time to time by an
     Issuer Order, (c) if so provided in or pursuant to the Board Resolution or
     supplemental indenture establishing the Securities of such series, the
     maturity date, original issue date, interest rate and any other terms of
     any or all of the Securities of such series may be determined by an Issuer
     Order or pursuant to such procedures and (d) if provided for in such
     procedures, such Issuer Order may authorize authentication and delivery
     pursuant to oral or electronic instructions from the Issuer or its duly
     authorized agent, which instructions shall be promptly confirmed in
     writing;

          (2)  any Board Resolution, Officers' Certificate and/or executed
     supplemental indenture referred to in Sections 2.1 and 2.3 by or pursuant
     to which the forms and terms of the Securities of such series and the
     Coupons, if any, were established;

          (3)  an Officers' Certificate setting forth the form or forms and
     terms of the Securities of such series and the Coupons, if any, stating
     that such form or forms and terms have been established pursuant to
     Sections 2.1 and 2.3 and comply with this Indenture, and covering such
     other matters as the Trustee may reasonably request; and

          (4)  at the option of the Issuer, either an Opinion of Counsel, or a
     letter addressed to the Trustee permitting it to rely on an Opinion of
     Counsel, substantially to the effect that:

               (a)  the forms of the Securities of such series and the Coupons,
          if any, have been duly authorized and established in conformity with
          the provisions of this Indenture;


                                   -14-



               (b)  in the case of an underwritten offering, the terms of the
          Securities of such series have been duly authorized and established in
          conformity with the provisions of this Indenture, and, in the case of
          an offering that is not underwritten, certain terms of the Securities
          of such series have been established pursuant to a Board Resolution,
          an Officers' Certificate or a supplemental indenture in accordance
          with the provisions of this Indenture and when such other terms as are
          to be established pursuant to an Issuer Order or procedures set forth
          in an Issuer Order shall have been established, all such terms will
          have been duly authorized by the Issuer and will have been established
          in conformity with the provisions of this Indenture;

               (c)  when the Securities of such series and the Coupons, if any,
          have been executed by the Issuer and authenticated by the Trustee in
          accordance with the provisions of this Indenture and delivered to and
          duly paid for by the purchasers thereof, they will have been duly
          issued under this Indenture and will be valid and legally binding
          obligations of the Issuer, enforceable in accordance with their
          respective terms, subject to bankruptcy, insolvency, reorganization
          and other laws of general applicability relating to or affecting the
          enforcement of creditors' rights and to general principles of equity,
          and will be entitled to the benefits of this Indenture;

               (d)  the execution and delivery by the Issuer of, and the
          performance by the Issuer of its obligations under, the Securities and
          Coupons, if any, will not contravene any provision of applicable law
          or the certificate of incorporation or by-laws of the Issuer or, to
          the best knowledge of such counsel, (i) any agreement or other
          instrument binding upon the Issuer or any of its subsidiaries that is
          material to the Issuer and its subsidiaries, considered as one
          enterprise, or (ii) any judgment, order or decree of any governmental
          body, agency or court having jurisdiction over the Issuer or any of
          its subsidiaries; and

               (e)  no consent, approval, authorization, order, registration or
          qualification of or with any governmental agency or body having
          jurisdiction over the Issuer is required for the execution and
          delivery of the Securities of such series by the Issuer, except such
          as have been obtained (except that no opinion need be expressed as to
          state securities or Blue Sky laws).


                                   -15-




          The Trustee shall have the right to decline to authenticate and 
deliver any Securities of any series under this Section (other than 
Securities the forms and terms of which shall have been established by 
supplemental indenture) if the Trustee, being advised by counsel, determines 
that such action may not lawfully be taken by the Issuer or if the Trustee in 
good faith by its board of directors or board of trustees, executive 
committee or a trust committee of directors, trustees or Responsible Officers 
shall determine that such action would expose the Trustee to personal 
liability to existing Holders or would affect the Trustee's rights, duties or 
immunities under the Securities of any such series, this Indenture or 
otherwise.

          If the Issuer shall establish pursuant to Section 2.3 that the 
Securities of a series are to be issued in the form of one or more Registered 
Global Securities, then the Issuer shall execute and the Trustee shall, in 
accordance with this Section and the Issuer Order with respect to such 
series, authenticate and deliver one or more Registered Global Securities 
that (i) shall be in an aggregate amount equal to the aggregate principal 
amount specified in such Issuer Order, (ii) shall be registered in the name 
of the Depositary therefor or its nominee, (iii) shall be delivered by the 
Trustee to such Depositary or pursuant to such Depositary's instructions and 
(iv) shall bear a legend substantially to the following effect: "Unless and 
until it is exchanged in whole or in part for Securities in definitive 
registered form, this Security may not be transferred except as a whole by 
the Depositary to the nominee of the Depositary or by a nominee of the 
Depositary to the Depositary or another nominee of the Depositary or by the 
Depositary or any such nominee to a successor Depositary or a nominee of such 
successor Depositary."

          Each Depositary designated pursuant to Section 2.3 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.

          SECTION 2.5  EXECUTION OF SECURITIES.  The Securities shall be 
signed on behalf of the Issuer by both (a) its Chairman of the Board of 
Directors or its President or any Vice President (whether or not designated 
by a number or numbers or a word or words added before or after the title 
"Vice President") and (b) by its Treasurer or any Assistant Treasurer or its 
Secretary or any Assistant Secretary, under its corporate seal (except in the 
case of Coupons) which may, but need not, be attested.  Such signatures may 
be the manual or facsimile signatures of the present or any future such 
officers.  The seal of the Issuer 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 


                                   -16-




authenticated and delivered by the Trustee.  The Coupons, if any, applicable 
to the Securities of any series shall bear the facsimile signature of the 
Treasurer or any Assistant Treasurer of the Issuer.

     In case any officer of the Issuer who shall have so signed any of the 
Securities or Coupons, if any, shall cease to be such officer before the 
Security or Coupon so signed (or the Security to which the Coupon so signed 
appertains) shall be authenticated and delivered by the Trustee or disposed 
of by the Issuer, such Security or Coupon nevertheless may be authenticated 
and delivered or disposed of as though the person who signed such Security or 
Coupon had not ceased to be such officer of the Issuer; and any Security or 
Coupon may be so signed on behalf of the Issuer by such persons as, at the 
actual date of the execution of such Security or Coupon, shall be the proper 
officers of the Issuer, although at the date of the execution and delivery of 
this Indenture any such person was not such an officer.

          SECTION 2.6  CERTIFICATE OF AUTHENTICATION.  Only such Securities 
as shall bear thereon a certificate of authentication substantially in the 
form hereinbefore recited, executed by the Trustee by the manual signature of 
one of its authorized officers, shall be entitled to the benefits of this 
Indenture or be valid or obligatory for any purpose.  No Coupon shall be 
entitled to the benefits of this Indenture or shall be valid and obligatory 
for any purpose until the certificate of authentication on the Security to 
which such Coupon appertains shall have been duly executed by the Trustee.  
The execution of such certificate by the Trustee upon any Security executed 
by the Issuer shall be conclusive evidence that the Security so authenticated 
has been duly authenticated and delivered hereunder and that the Holder is 
entitled to the benefits of this Indenture.

          SECTION 2.7  DENOMINATION AND DATE OF SECURITIES, PAYMENTS OF 
INTEREST.  The Securities of each series shall be issuable as Registered 
Securities or Unregistered Securities in denominations established as 
contemplated by Section 2.3 or, with respect to the Registered Securities of 
any series, if not so established, in denominations of $1,000 and any 
integral multiple thereof.  If denominations of Unregistered Securities of 
any series are not so established, such Securities shall be issuable in 
denominations of $1,000 and $5,000.  The Securities of each series shall be 
numbered, lettered or otherwise distinguished in such manner or in accordance 
with such plan as the officers of the Issuer executing the same may determine 
with the approval of the Trustee, as evidenced by the execution and 
authentication thereof.


                                   -17-




          Each Registered Security shall be dated the date of its 
authentication.  Each Unregistered Security shall be dated as established in 
or pursuant to the Board Resolution or supplemental indenture referred to in 
Section 2.3. The Securities of each series shall bear interest, if any, from 
the date, and such interest shall be payable on the dates, established as 
contemplated by Section 2.3.

          Except as may otherwise be established pursuant to Section 2.3, the 
Person in whose name any Registered Security of any series is registered at 
the close of business on any Record Date applicable to such series with 
respect to any interest payment date for such series shall be entitled to 
receive the interest, if any, payable on such interest payment date 
notwithstanding any transfer or exchange of such Registered Security 
subsequent to the Record Date and prior to such interest payment date, except 
if and to the extent the Issuer shall default in the payment of the interest 
due on such interest payment date, in which case such defaulted interest may, 
at the option of the Issuer, be paid to the Persons in whose names 
Outstanding Registered Securities of such series are registered at the close 
of business on a subsequent special Record Date (which shall be not less than 
five Business Days prior to the date of payment of such defaulted interest) 
established by notice given by mail by or on behalf of the Issuer to the 
Holders of Registered Securities of such series not less than 15 days 
preceding such subsequent special Record Date.  The term "Record Date", as 
used with respect to any interest payment date (except a special Record Date 
set for payment of defaulted interest) for the Securities of any series, 
shall mean the date specified as such in the terms of the Registered 
Securities of such series established as contemplated by Section 2.3.

          SECTION 2.8  REGISTRATION, TRANSFER AND EXCHANGE.  The Issuer will 
keep, or cause to be kept, at the Corporate Trust Office or at another office 
or agency to be maintained for the purpose as provided in Section 3.2, for 
each series of Securities a register (the "Security Register") in which, 
subject to such reasonable regulations as it may prescribe, it will provide 
for the registration of Registered Securities of such series and the 
registration of transfer of Registered Securities of such series.  The 
Security Register shall be in written form in the English language or in any 
other form capable of being converted into such form within a reasonable 
time.  At all reasonable times such register not maintained by the Trustee 
shall be open for inspection by the Trustee.  Unless and until otherwise 
determined by the Issuer pursuant to Section 2.3, the Security Register with 
respect to each series of Registered Securities shall be kept solely at the 
Corporate Trust Office and, for this purpose, the Trustee shall be designated 
the "Security Registrar".


                                   -18-




          Upon due presentation for registration of transfer of any 
Registered Security of any series at any office or agency to be maintained 
for the purpose as provided in Section 3.2 for such series, the Issuer shall 
execute and the Trustee shall authenticate and deliver in the name of the 
transferee or transferees a new Registered Security or Registered Securities 
of the same series, maturity date and interest rate in authorized 
denominations for a like aggregate principal amount.

          Unregistered Securities (except for any temporary global 
Unregistered Securities) and Coupons (except for Coupons attached to any 
temporary global Unregistered Securities) shall be transferable by delivery.

          At the option of the Holder thereof, Registered Securities of any 
series (other than a Registered Global Security, except as set forth below) 
may be exchanged for one or more Registered Securities of such series in 
authorized denominations for a like aggregate principal amount, upon 
surrender of such Registered Securities to be exchanged at the office or 
agency to be maintained for such purpose in accordance with Section 3.2 and 
upon payment, if the Issuer shall so require, of the charges hereinafter 
provided.  If the Securities of any series are issued in both registered and 
unregistered form, except as otherwise specified for a particular series 
pursuant to Section 2.3, at the option of the Holder thereof, Unregistered 
Securities of any series may be exchanged for Registered Securities of such 
series in authorized denominations for a like aggregate principal amount, 
upon surrender of such Unregistered Securities to be exchanged at the office 
or agency to be maintained for such purpose in accordance with Section 3.2, 
with, in the case of Unregistered Securities that have Coupons attached, all 
unmatured Coupons and all matured Coupons in default thereto appertaining, 
and upon payment, if the Issuer shall so require, of the charges hereinafter 
provided.  At the option of the Holder thereof, if Unregistered Securities of 
any series, maturity date, interest rate and original issue date are issued 
in more than one authorized denomination, except as otherwise specified for a 
particular series pursuant to Section 2.3, such Unregistered Securities may 
be exchanged for other Unregistered Securities of such series in authorized 
denominations for a like aggregate principal amount, upon surrender of such 
Unregistered Securities to be exchanged at the office or agency to be 
maintained for such purpose in accordance with Section 3.2 or as specified 
for a particular series pursuant to Section 2.3, with, in the case of 
Unregistered Securities that have Coupons attached, all unmatured Coupons and 
all matured Coupons in default thereto appertaining, and upon payment, if the 
Issuer shall so require, of the charges hereinafter provided.  Unless 
otherwise specified for a particular series pursuant to Section 2.3, 
Registered Securities of any series may not be exchanged for Unregistered 
Securities of such series.  Whenever 


                                   -19-





any securities are so surrendered for exchange, the Issuer shall execute, and 
the Trustee shall authenticate and deliver, the Securities which the Holder 
making the exchange is entitled to receive.  All Securities and Coupons 
surrendered upon any exchange or transfer provided for in this Indenture 
shall be promptly cancelled and disposed of (subject to the record retention 
requirements of the Exchange Act) by the Trustee and the Trustee will deliver 
a certificate of disposition thereof to the Issuer.

     All Registered Securities presented for registration of transfer, 
exchange, redemption or payment shall (if so required by the Issuer or the 
Trustee) be duly endorsed by, or be accompanied by a written instrument or 
instruments of transfer in form satisfactory to the Issuer and the Trustee 
duly executed by, the Holder or his attorney duly authorized in writing.

     The Issuer may require payment of a sum sufficient to cover any tax or 
other governmental charge that may be imposed in connection with any exchange 
or registration of transfer of Securities.  No service charge shall be made 
for any such transaction.

     The Issuer shall not be required to (a) issue, exchange or register a 
transfer of any Securities of any series for a period of 15 days next 
preceding the first mailing or publication of notice of redemption of 
Securities of such series to be redeemed, (b) exchange or register the 
transfer of any Securities selected, called or being called for redemption, 
in whole or in part, except, in the case of any Security to be redeemed in 
part, the portion thereof not so to be redeemed or (c) register the transfer 
of or exchange any Security if the Holder thereof has exercised his right, if 
any, to require the Issuer to repurchase such Security, in whole or in part, 
except the portion of such Security required to be repurchased.

     Notwithstanding any other provision of this Section, unless and until it 
is exchanged in whole or in part for Securities in definitive registered 
form, a Registered Global Security representing all or a portion of the 
Securities of a series may not be transferred except as a whole by the 
Depositary for such Registered Global Security to a nominee of such 
Depositary or by a nominee of such Depositary to such Depositary or another 
nominee of such Depositary or by such Depositary or any such nominee to a 
successor Depositary for such Registered Global Security or a nominee of such 
successor Depositary.

     If at any time a Depositary for any Registered Securities of a series 
represented by one or more Registered Global Securities notifies the Issuer 
that it is unwilling or unable to continue as Depositary for such Registered 
Securities or if at any time any such Depositary shall no longer be eligible 
under Section 2.4, 


                                   -20-




the Issuer shall appoint a successor Depositary with respect to the 
Registered Securities held by such Depositary.  If a successor Depositary is 
not appointed by the Issuer within 90 days after the Issuer receives such 
notice or becomes aware of such ineligibility, the Registered Securities of 
such series shall no longer be represented by one or more Registered Global 
Securities held by such Depositary, and the Issuer shall execute, and the 
Trustee, upon receipt of an Issuer Order for the authentication and delivery 
of definitive Securities of such series, shall authenticate and deliver 
Securities of such series in definitive registered form without Coupons, in 
any authorized denominations and in an aggregate principal amount equal to 
the principal amount of the Registered Global Security or Securities held by 
such Depositary in exchange for such Registered Global Security or Securities.

     Within seven days after the occurrence of an Event of Default specified 
in clause (a), (b) or (c) of Section 5.1 with respect to any series of 
Securities that is, in whole or in part, represented by a Registered Global 
Security, the Issuer shall execute, and the Trustee shall authenticate and 
deliver, Securities of such series in definitive registered form without 
coupons, in any authorized denominations and in an aggregate principal amount 
equal to the principal amount of the Registered Global Security or Securities 
representing Registered Securities of such series in exchange for such 
Registered Global Security or Securities.

     The Issuer may at any time and in its sole discretion determine that the 
Registered Securities of a particular series shall no longer be represented 
by a Registered Global Security or Securities.  In such event, the Issuer 
shall execute, and the Trustee, upon receipt of an Issuer Order for the 
authentication and delivery of definitive Securities of such series, shall 
authenticate and deliver, Securities of such series in definitive registered 
form without Coupons, in any authorized denominations and in an aggregate 
principal amount equal to the principal amount of the Registered Global 
Security or Securities representing Registered Securities of such series in 
exchange for such Registered Global Security or Securities.

     If so specified by the Issuer pursuant to Section 2.3 with respect to 
Securities of a particular series represented by a Registered Global 
Security, the Depositary for such Registered Global Security may surrender 
such Registered Global Security in exchange in whole or in part for 
Securities of such series in definitive registered form on such terms as are 
acceptable to the Issuer and such Depositary.  Thereupon, the Issuer shall 
execute, and the Trustee shall authenticate and deliver:

          (i)  to each Person specified by such Depositary a new Registered
     Security or securities of such series, in any 


                                   -21-



     authorized denominations requested by such Person, in an aggregate 
     principal amount equal to, and in exchange for, such Person's beneficial 
     interest in the Registered Global Security; and

          (ii)  to such Depositary a new Registered Global security in a
     denomination equal to the difference between the principal amount of the
     surrendered Registered Global Security and the aggregate principal amount
     of Registered Securities authenticated and delivered pursuant to clause (i)
     above.

          Upon the exchange of any Registered Global Security for Securities 
in definitive registered form without Coupons, in authorized denominations, 
such Registered Global Security shall be canceled by the Trustee or an agent 
of the Issuer or the Trustee.  Securities in definitive registered form 
without Coupons issued in exchange for a Registered Global Security pursuant 
to this Section shall be registered in such names and in such authorized 
denominations as the Depositary for such Registered Global Security, pursuant 
to instructions from its direct or indirect participants or otherwise, shall 
instruct the Trustee or an agent of the Issuer or the Trustee.  The Trustee 
or such agent shall deliver such Securities to or as directed by the Persons 
in whose names such Securities are so registered.

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

          Notwithstanding anything herein or in the terms of any series of 
Securities to the contrary, none of the Issuer, the Trustee or any agent of 
the Issuer or the Trustee (any of which, other than the Issuer, shall rely on 
an Officers' Certificate and an Opinion of Counsel) shall be required to 
exchange any Unregistered Security for a Registered Security if such exchange 
would result in adverse Federal income tax consequences to the Issuer (such 
as, for example, the inability of the Issuer to deduct from its income, as 
computed for Federal income tax purposes, the interest payable on the 
Unregistered Securities) under then applicable United States Federal income 
tax laws.

          SECTION 2.9  MUTILATED, DEFACED, DESTROYED, LOST AND STOLEN 
SECURITIES.  In case any temporary or definitive Security or any Coupon 
appertaining to any Security shall become mutilated, defaced or be destroyed, 
lost or stolen, the Issuer shall execute, and upon receipt of an Issuer 
Order, the Trustee shall authenticate and deliver a new Security of the same 
series, maturity date, interest rate and original issue date, bearing a 
number or other distinguishing symbol not contemporaneously


                                   -22-




outstanding, in exchange and substitution for the mutilated or defaced 
Security, or in lieu of and in substitution for the Security so destroyed, 
lost or stolen, with Coupons corresponding to the Coupons appertaining to the 
Securities so mutilated, defaced, destroyed, lost or stolen, or in exchange 
or substitution for the Security to which such mutilated, defaced, destroyed, 
lost or stolen Coupon appertained, with Coupons appertaining thereto 
corresponding to the Coupons so mutilated, defaced, destroyed, lost or 
stolen.  In every case the applicant for a substitute Security or Coupon 
shall furnish to the Issuer and to the Trustee and any agent of the Issuer or 
the Trustee such security or indemnity as may be required by them to 
indemnify and defend and to save each of them harmless and, in every case of 
destruction, loss or theft, evidence to their satisfaction of the 
destruction, loss or theft of such Security or Coupon and of the ownership 
thereof and, in the case of mutilation or defacement, shall surrender the 
Security and related Coupons to the Trustee or such agent.

          Upon the issuance of any substitute Security or Coupon, the Issuer 
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 or its agent) 
connected therewith.  In case any Security or Coupon which has matured or is 
about to mature or has been called for redemption in full shall become 
mutilated or defaced or be destroyed, lost or stolen, the Issuer may, instead 
of issuing a new or substitute Security, pay or authorize the payment of the 
same or the relevant Coupon (without surrender thereof except in the case of 
a mutilated or defaced Security or Coupon), if the applicant for such payment 
shall furnish to the Issuer and to the Trustee and any agent of the Issuer or 
the Trustee such security or indemnity as may be required by them to save 
each of them harmless, and, in every case of destruction, loss or theft, 
evidence to their satisfaction of the destruction, loss or theft of such 
Security or Coupon and of the ownership thereof and, in the case of 
mutilation or defacement, shall surrender the Security and related Coupons to 
the Trustee or such agent.

     Every substitute Security or Coupon of any series issued pursuant to the 
provisions of this Section by virtue of the fact that any such Security or 
Coupon is destroyed, lost or stolen shall constitute an additional 
contractual obligation of the Issuer, whether or not the destroyed, lost or 
stolen Security or Coupon shall be at any time enforceable by anyone and 
shall be entitled to all the benefits of (but shall be subject to all the 
limitations of rights set forth in) this Indenture equally and 
proportionately with any and all other Securities or Coupons of such series 
duly authenticated and delivered hereunder. All Securities and Coupons shall 
be held and owned upon the express condition that, to the extent permitted by 
law, the foregoing 


                                   -23-



provisions are exclusive with respect to the replacement or payment of 
mutilated, defaced, destroyed, lost or stolen Securities and Coupons and 
shall preclude any and all other rights or remedies notwithstanding any law 
or statute existing or hereafter enacted to the contrary with respect to the 
replacement or payment of negotiable instruments or other securities without 
their surrender.

     SECTION 2.10  CANCELLATION OF SECURITIES; DISPOSITION THEREOF.  All 
Securities and Coupons surrendered for payment, redemption, registration of 
transfer or exchange, or for credit against any payment in respect of a 
sinking or analogous fund, if surrendered to the Issuer or any agent of the 
Issuer or any agent of the Trustee, shall be delivered to the Trustee or its 
agent for cancellation or, if surrendered to the Trustee, shall be canceled 
by it; and no Securities or Coupons shall be issued in lieu thereof except as 
expressly permitted by any of the provisions of this Indenture.  The Trustee 
or its agent shall dispose of canceled Securities and Coupons held by it 
(subject to the record retention requirements of the Exchange Act) and 
deliver a certificate of disposition to the Issuer.  If the Issuer or its 
agent shall acquire any of the Securities or Coupons, such acquisition shall 
not operate as a redemption or satisfaction of the indebtedness represented 
by such Securities or Coupons unless and until the same are delivered to the 
Trustee or its agent for cancellation.

     SECTION 2.11  TEMPORARY SECURITIES.  Pending the preparation of 
definitive Securities for any series, the Issuer may execute and the Trustee 
shall authenticate and deliver temporary Securities for such series (printed, 
lithographed, typewritten or otherwise reproduced, in each case in form 
satisfactory to the Trustee).  Temporary Securities of any series shall be 
issuable as Registered Securities without coupons, or as Unregistered 
Securities with or without coupons attached thereto, of any authorized 
denomination, and substantially in the form of the definitive Securities of 
such series but with such omissions, insertions and variations as may be 
appropriate for temporary Securities, all as may be determined by the Issuer 
with the concurrence of the Trustee as evidenced by the execution and 
authentication thereof.  Temporary Securities may contain such references to 
any provisions of this Indenture as may be appropriate.  Every temporary 
Security shall be executed by the Issuer and be authenticated by the Trustee 
upon the same conditions and in substantially the same manner, and with like 
effect, as the definitive Securities.  Without unreasonable delay the Issuer 
shall execute and shall furnish definitive Securities of such series and 
thereupon temporary Registered Securities of such series may be surrendered 
in exchange for such definitive Securities in registered form without charge 
at each office or agency to be maintained for such purpose in accordance with 
Section 3.2 and, in the case of Unregistered Securities, at any 


                                   -24-




office or agency to be maintained for such purpose as specified pursuant to 
Section 2.3, and the Trustee shall authenticate and deliver in exchange for 
such temporary Securities of such series an equal aggregate principal amount 
of definitive Securities of the same series in authorized denominations and, 
in the case of Unregistered Securities, having attached thereto any 
appropriate Coupons.  Until so exchanged, the temporary Securities of any 
series shall be entitled to the same benefits under this Indenture as 
definitive Securities of such series, unless otherwise established pursuant 
to Section 2.3.  The provisions of this Section are subject to any 
restrictions or limitations on the issue and delivery of temporary 
Unregistered Securities of any series that may be established pursuant to 
Section 2.3 (including any provision that Unregistered Securities of such 
series initially be issued in the form of a single global Unregistered 
Security to be delivered to a depositary or agency located outside the United 
States and the procedures pursuant to which definitive Unregistered 
Securities of such series would be issued in exchange for such temporary 
global Unregistered Security).

                                    ARTICLE THREE

                               COVENANTS OF THE ISSUER

     SECTION 3.1  PAYMENT OF PRINCIPAL AND INTEREST.  The Issuer covenants 
and agrees for the benefit of each series of Securities that it will duly and 
punctually pay or cause to be paid the principal of, and interest on, each of 
the Securities of such series (together with any additional amounts payable 
pursuant to the terms of such Securities) at the place or places, at the 
respective times and in the manner provided in such Securities and in the 
Coupons, if any, appertaining thereto and in this Indenture.  The interest on 
Securities with Coupons attached (together with any additional amounts 
payable pursuant to the terms of such Securities) shall be payable only upon 
presentation and surrender of the several Coupons for such interest 
installments as are evidenced thereby as they severally mature.  If any 
temporary Unregistered Security provides that interest thereon may be paid 
while in temporary form, the interest on any such temporary Unregistered 
Security (together with any additional amounts payable pursuant to the terms 
of such Security) shall be paid, as to the installments of interest evidenced 
by Coupons attached thereto, if any, only upon presentation and surrender 
thereof, and, as to the other installments of interest, if any, only upon 
presentation of such temporary Unregistered Security for notation thereon of 
the payment of such interest, in each case subject to any restrictions that 
may be established pursuant to Section 2.3.  The interest on Registered 
Securities (together with any additional amounts payable pursuant to the 
terms of such Securities) shall 


                                   -25-




be payable only to or upon the written order of the Holders thereof and, at 
the option of the Issuer (unless otherwise specified in such Securities), may 
be paid by wire transfer or by mailing checks for such interest payable to or 
upon the written order of such Holders at their last addresses as they appear 
on the registry books of the Issuer.

     Principal and interest shall be considered paid on the date due if on 
such date the Trustee or the paying agent holds in accordance with this 
Indenture money sufficient to pay all principal and interest then due and the 
Trustee or the paying agent, as the case may be, is not prohibited pursuant 
to the terms of this Indenture from paying such money to the Securityholders 
on that date.

     SECTION 3.2  OFFICES FOR PAYMENTS, ETC.  So long as any Registered 
Securities are outstanding hereunder, the Issuer will maintain in the Borough 
of Manhattan, The City of New York, an office or agency where the Registered 
Securities of each series may be presented for payment, where the Securities 
of each series may be presented for exchange as in this Indenture provided 
and where the Registered Securities of each series may be presented for 
registration of transfer as in this Indenture provided.

     In the event that the Issuer shall issue any Unregistered Securities, it 
will maintain one or more offices or agencies in a city or cities located 
outside the United States (including any city in which such an office or 
agency is required to be maintained under the rules of any stock exchange on 
which the Securities of any series are listed) where the Unregistered 
Securities, if any, of each series and Coupons, if any, appertaining thereto 
may be presented for payment.  No payment on any Unregistered Security or 
Coupon will be made upon presentation of such Unregistered Security or Coupon 
at an office or agency of the Issuer within the United States, nor will any 
payment be made by transfer to an account in, or by mail to an address in, 
the United States unless pursuant to applicable United States laws and 
regulations then in effect such payment can be made without adverse tax 
consequences to the Issuer.  Notwithstanding the foregoing, payments in 
Dollars on Unregistered Securities of any series and Coupons appertaining 
thereto which are payable in Dollars may be made at an office or agency of 
the Issuer maintained in the Borough of Manhattan, The City of New York, if 
such payment in Dollars at each office or agency maintained by the Issuer 
outside the United States for payment on such Unregistered Securities is 
illegal or effectively precluded by exchange controls or other similar 
restrictions.

     The Issuer will maintain in the Borough of Manhattan, The City of New 
York, an office or agency where notices and demands to or upon the Issuer in 
respect of the Securities of any series, the Coupons appertaining thereto or 
this Indenture may be served.


                                   -26-




     The Issuer will give to the Trustee written notice of the location of 
each such office or agency and of any change of location thereof.  In case 
the Issuer shall fail to maintain any office or agency required by this 
Section to be located in the Borough of Manhattan, The City of New York, or 
shall fail to give such notice of the location or of any change in the 
location of any of the above offices or agencies, presentations and demands 
may be made and notices may be served at the Corporate Trust Office of the 
Trustee.

     The Issuer may from time to time designate one or more additional 
offices or agencies where the Securities of any series and any Coupons 
appertaining thereto may be presented for payment, where the Securities of 
such series may be presented for exchange as in this Indenture provided and 
where the Registered Securities of such series may be presented for 
registration of transfer as in this Indenture provided, and the Issuer may 
from time to time rescind any such designation; PROVIDED, HOWEVER, that no 
such designation or rescission shall in any manner relieve the Issuer of its 
obligation to maintain any office or agency required to be provided for in 
this Section.  The Issuer will give to the Trustee prompt written notice of 
any such designation or rescission thereof.

          SECTION 3.3  APPOINTMENT TO FILL A VACANCY IN OFFICE OF TRUSTEE.  
The Issuer, whenever necessary to avoid or fill a vacancy in the office of 
Trustee, will appoint, in the manner provided in Section 6.10, a Trustee, so 
that there shall at all times be a Trustee with respect to each series of 
Securities hereunder.

          SECTION 3.4  PAYING AGENTS.  Whenever the Issuer shall appoint a 
paying agent other than the Trustee with respect to the Securities of any 
series, it will cause such paying agent to execute and deliver to the Trustee 
an instrument in which such agent shall agree with the Trustee, subject to 
the provisions of this Section:

          (a)  that it will hold all sums received by it as such agent for the
     payment of the principal of or interest on the Securities of such series
     (whether such sums have been paid to it by the Issuer or by any other
     obligor on the Securities of such series) in trust for the benefit of the
     Holders of the Securities of such series and the Coupons appertaining
     thereto, if any, or of the Trustee, and

          (b)  that it will give the Trustee notice of any failure by the Issuer
     (or by any other obligor on the Securities of such series) to make any
     payment of the principal of or interest on the Securities of such series
     when the same shall be due and payable, and


                                   -27-




          (c)  that at any time during the continuance of any such failure
     referred to in the foregoing paragraph (b), it will upon written request of
     the Trustee forthwith pay to the Trustee all sums so held in trust by such
     agent.

          The Issuer will, on or prior to each due date of the principal of 
or interest on the Securities of any series, deposit with the paying agent a 
sum sufficient to pay such principal or interest so becoming due, and (unless 
such paying agent is the Trustee) the Issuer will promptly notify the Trustee 
of any failure to take such action.

          If the Issuer shall act as its own paying agent with respect to the 
Securities of any series, it will, on or before each due date of the 
principal of or interest on the Securities of such series, set aside, 
segregate and hold in trust for the benefit of the Holders of the Securities 
of such series or the Coupons, if any, appertaining thereto a sum sufficient 
to pay such principal or interest so becoming due.  The Issuer will promptly 
notify the Trustee of any failure to take such action.

          Anything in this section to the contrary notwithstanding, but 
subject to Section 10.1, the Issuer may at any time, for the purpose of 
obtaining a satisfaction and discharge with respect to one or more or all 
series of Securities hereunder, or for any other reason, pay or cause to be 
paid to the Trustee all sums held in trust for any such series by the Issuer 
or any paying agent hereunder, as required by this Section, such sums to be 
held by the Trustee upon the trusts herein contained.

          Anything in this Section to the contrary notwithstanding, the 
agreement to hold sums in trust as provided in this Section is subject to the 
provisions of Sections 10.3 and 10.4.

          SECTION 3.5  WRITTEN STATEMENT TO TRUSTEE.  The Issuer will deliver 
to the Trustee on or before April 30 in each year (beginning with April 30, 
1998) an Officers' Certificate (which need not comply with Section 11.5) 
stating that in the course of the performance by the signers of their duties 
as officers of the Issuer they would normally have knowledge of any default 
by the Issuer in the performance of any covenants contained in this 
Indenture, stating whether or not they have knowledge of any such default 
and, if so, specifying each such default of which the signers have knowledge 
and the nature thereof.

          SECTION 3.6  LIMITATION ON SECURED DEBT.  So long as any of the 
Securities remain Outstanding, the Issuer will not create or incur any 
Secured Debt without in any such case effectively providing concurrently with 
the creation or incurrence of any such Secured Debt that the Securities then 


                                   -28-




Outstanding (together with, if the Issuer shall so determine, any other Debt 
of or guaranteed by the Issuer ranking equally with the Securities and then 
existing or thereafter created) shall be secured equally and ratably with 
(or, at the option of the Issuer, prior to) such Secured Debt, unless 
immediately after the incurrence of such Secured Debt (and after giving 
effect to the application of the proceeds, if any, therefrom), the aggregate 
principal amount of all such Secured Debt, together with the aggregate amount 
of Capitalized Rent in respect of Sale and Leaseback Transactions (other than 
Sale and Leaseback Transactions described in clauses (a) to (e), inclusive, 
of Section 3.7), would not exceed 10% of Consolidated Capitalization; 
PROVIDED, HOWEVER, that the foregoing restrictions shall not apply to, and 
there shall be excluded in computing Secured Debt for the purpose of such 
restrictions, Secured Debt secured by:

          (a)  Liens on property existing at the time of acquisition of such
     property by the Issuer, or Liens to secure the payment of all or any part
     of the purchase price of property acquired or constructed by the Issuer
     (including any improvements to existing property) created at the time of or
     within 270 days following the acquisition of such property by the Issuer,
     or Liens to secure any Secured Debt incurred by the Issuer prior to, at the
     time of or within 270 days following the acquisition of such property,
     which Secured Debt is incurred for the purpose of financing all or any part
     of the purchase price thereof; PROVIDED, HOWEVER, that in the case of any
     such acquisition, the Lien shall not apply to any property theretofore
     owned by the Issuer (including property transferred by the Issuer to any
     subsidiary of the Issuer in contemplation of or in connection with the
     creation of such Lien) or to any property of the Issuer other than the
     property so acquired (other than, in the case of construction or
     improvement, any theretofore unimproved real property or portion thereof on
     which the property so constructed, or the improvement, is located);

          (b)  Liens on property of a Person (i) existing at the time such
     Person is merged into or consolidated with the Issuer or at the time of a
     sale, lease or other disposition of the properties of a Person as an
     entirety or substantially as an entirety to the Issuer, (ii) resulting from
     such merger, consolidation, sale, lease or disposition by virtue of any
     Lien on property granted by the Issuer prior to such merger, consolidation,
     sale, lease or disposition (and not in contemplation thereof or in
     connection therewith) which applies to after-acquired property of the
     Issuer or (iii) resulting from such merger, consolidation, sale, lease or
     disposition pursuant to a Lien or contractual provision granted or entered
     into by such Person prior to such merger, consolidation, sale, lease or
     disposition (and not at the request of the Issuer); PROVIDED, HOWEVER, that


                                   -29-




     any such Lien referred to in clause (i) shall not apply to any property of
     the Issuer other than the property subject thereto at the time such Person
     or properties were acquired and any such Lien referred to in clause (ii) or
     (iii) shall not apply to any property of the Issuer other than the property
     so acquired;

          (c)  Liens existing on the date of this Indenture;

          (d)  Liens in favor of a government or governmental entity to secure
     partial progress, advance or other payments, or other obligations, pursuant
     to any contract or statute or to secure any Debt incurred for the purpose
     of financing all or any part of the cost of acquiring, constructing or
     improving the property subject to such Liens (including, without
     limitation, Liens incurred in connection with pollution control, industrial
     revenue, private activity bond or similar financing);

          (e)  Liens arising by reason of deposits with, or the giving of any
     form of security to, any governmental agency or any body created or
     approved by law or governmental regulation, which Lien is required by law
     or governmental regulation as a condition to the transaction of any
     business or the exercise of any privilege, franchise, license or permit;

          (f)  Liens for taxes, assessments or governmental charges or levies
     not yet delinquent or governmental charges or levies already delinquent,
     the validity of which charge or levy is being contested in good faith and
     for which any reserves required in accordance with generally accepted
     accounting principles have been established;

          (g)  Liens (including judgment liens) arising in connection with legal
     proceedings so long as such proceedings are being contested in good faith
     and, in the case of judgment liens, execution thereon is stayed and for
     which any reserves required in accordance with generally accepted
     accounting principles have been established; and

          (h)  any extension, renewal or replacement (or successive extensions,
     renewals or replacements) in whole or in part of any Lien referred to in
     the foregoing clauses (a) to (g), inclusive; PROVIDED, HOWEVER, that the
     principal amount of Secured Debt secured thereby shall not exceed the
     principal amount of Secured Debt secured thereby at the time of such
     extension, renewal or replacement, and that such extension, renewal or
     replacement shall be limited to all or a part of the property which secured
     the Lien so extended, renewed or replaced (plus improvements to such
     property).


                                   -30-




          SECTION 3.7  LIMITATION ON SALE AND LEASEBACK.  So long as any of 
the Securities remain outstanding, the Issuer will not enter into any Sale 
and Leaseback Transaction unless immediately thereafter (and after giving 
effect to the application of the proceeds, if any, therefrom), the aggregate 
amount of Capitalized Rent in respect of Sale and Leaseback Transactions, 
together with the aggregate principal amount of all Secured Debt (other than 
Secured Debt described in clauses (a) to (h), inclusive, of Section 3.6), 
would not exceed 10% of Consolidated Capitalization; PROVIDED, HOWEVER, that 
the foregoing restrictions shall not apply to, and there shall be excluded in 
computing the aggregate amount of Capitalized Rent for the purpose of such 
restrictions, the following Sale and Leaseback Transactions:

          (a)  any Sale and Leaseback Transaction entered into to finance the
     payment of all or any part of the purchase price of property acquired or
     constructed by the Issuer (including any improvements to existing property)
     or entered into prior to, at the time of or within 270 days after the
     acquisition or construction of such property, which Sale and Leaseback
     Transaction is entered into for the purpose of financing all or part of the
     purchase or construction price thereof; PROVIDED, HOWEVER, that in the case
     of any such acquisition, such Sale and Leaseback Transaction shall not
     involve any property transferred by the Issuer to a subsidiary of the
     Issuer in contemplation of or in connection with such Sale and Leaseback
     Transaction or involve any property of the Issuer other than the property
     so acquired (other than, in the case of construction or improvement, any
     theretofore unimproved real property or portion thereof on which the
     property so constructed, or the improvement, is located);

          (b)  any Sale and Leaseback Transaction involving property of a Person
     existing at the time such Person is merged into or consolidated with the
     Issuer or at the time of a sale, lease or other disposition of the
     properties of a Person as an entirety or substantially as an entirety to
     the Issuer;

          (c)  any Sale and Leaseback Transaction in which the lessor is a
     government or governmental entity and which Sale and Leaseback Transaction
     is entered into to secure partial progress, advance or other payments, or
     other obligations, pursuant to any contract or statute or to secure any
     Debt incurred for the purpose of financing all or any part of the cost of
     constructing or improving the property subject to such Sale and Leaseback
     Transaction (including, without limitation, Sale and Leaseback Transactions
     incurred in connection with pollution control, industrial revenue, private
     activity bond or similar financing);


                                   -31-



          (d)  any Sale and Leaseback Transaction involving the extension,
     renewal or replacement (or successive extensions, renewals or replacements)
     in whole or in part of a lease pursuant to a Sale and Leaseback Transaction
     referred to in the foregoing clauses (a) to (c), inclusive; PROVIDED,
     HOWEVER, that such lease extension, renewal or replacement shall be limited
     to all or any part of the same property leased under the lease so extended,
     renewed or replaced (plus improvements to such property); and

          (e)  any Sale and Leaseback Transaction the net proceeds of which are
     at least equal to the fair value (as determined by the Board of Directors)
     of the property leased pursuant to such Sale and Leaseback Transaction, so
     long as within 270 days of the effective date of such Sale and Leaseback
     Transaction, the Issuer applies (or irrevocably commits to an escrow
     account for the purpose or purposes hereinafter mentioned) an amount equal
     to the net proceeds of such Sale and Leaseback Transaction to either (x)
     the purchase of other property having a fair value at least equal to the
     fair value of the property leased in such Sale and Leaseback Transaction
     and having a similar utility and function, or (y) the retirement or
     repayment (other than any mandatory retirement or repayment at maturity) of
     (i) Securities, (ii) other Funded Debt of the Issuer which ranks prior to
     or on a parity with the Securities or (iii) indebtedness of any subsidiary
     of the Issuer maturing by its terms more than one year from its date of
     issuance (notwithstanding that any portion of such indebtedness is included
     in current liabilities) or preferred stock of any subsidiary of the Issuer
     (other than any such indebtedness owed to or preferred stock owned by the
     Issuer or any subsidiary of the Issuer); PROVIDED, HOWEVER, that in lieu of
     applying an amount equivalent to all or any part of such net proceeds to
     such retirement or repayment (or committing such an amount to an escrow
     account for such purpose), the Issuer may deliver to the Trustee
     Outstanding Securities and thereby reduce the amount to be applied pursuant
     to (y) of this clause (e) by an amount equivalent to the aggregate
     principal amount of the Securities so delivered.

                       SECURITYHOLDERS LISTS AND REPORTS BY THE
                                ISSUER AND THE TRUSTEE    

          SECTION 4.1  ISSUER TO FURNISH TRUSTEE NAMES AND ADDRESSES OF 
SECURITYHOLDERS.  The Issuer and any other obligor on the Securities covenant 
and agree that they will furnish or cause to be furnished to the Trustee a 
list in such form as the 


                                   -32-




Trustee may reasonably require of the names and addresses of the Holders of 
the Registered Securities of each series:

          (a)  semi-annually and not more than 15 days after each Record Date
     for the payment of interest on such Registered Securities, as of such
     Record Date and on dates to be determined pursuant to Section 2.3 for 
     non-interest bearing Registered Securities, in each year, and

          (b)  at such other times as the Trustee may request in writing, within
     30 days after receipt by the Issuer of any such request, as of a date not
     more than 15 days prior to the time such information is furnished,

PROVIDED that if and so long as the Trustee shall be the Security Registrar 
for such series and all of the Securities of such series are Registered 
Securities, such list shall not be required to be furnished.

          SECTION 4.2 PRESERVATION AND DISCLOSURE OF SECURITYHOLDERS LISTS. 
(a) The Trustee shall preserve, in as current a form as is reasonably 
practicable, all information as to the names and addresses of the Holders of 
each series of Registered Securities (i) contained in the most recent list 
furnished to it as provided in Section 4.1, (ii) received by it in the 
capacity of Security Registrar for such series, if so acting, and (iii) filed 
with it within the two preceding years pursuant to Section 4.4(c)(ii). The 
Trustee may destroy any list furnished to it as provided in Section 4.1 upon 
receipt of a new list so furnished.

          (b)  In case three or more Holders of Securities (hereinafter 
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 of Securities of a particular series (in which case the 
applicants must all hold Securities of such series) or with Holders of all 
Securities with respect to their rights under this Indenture or under such 
Securities and such application 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 to such applicants access to the information preserved at
     the time by the Trustee in accordance with the provisions of subsection (a)
     of this Section, or


                                   -33-




          (ii)  inform such applicants as to the approximate number of Holders
     of Registered Securities of such series or of all Registered Securities, as
     the case may be, whose names and addresses appear in the information
     preserved at the time by the Trustee, in accordance with the provisions of
     such subsection (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.

          If the Trustee shall elect not to afford to such applicants access 
to such information, the Trustee shall, upon the written request of such 
applicants, mail to each Holder of such series or all Holders of Registered 
Securities, whose name and address appears in the information preserved at 
the time by the Trustee in accordance with the provisions of such subsection 
(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 of Registered Securities of such series or of 
all Registered Securities, as the case may be, 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 the 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)  Each and every Holder of Securities and Coupons, by receiving 
and holding the same, agrees with the Issuer and the Trustee that neither the 
Issuer nor the Trustee nor any agent of the Issuer or the Trustee shall be 
held accountable by reason of the disclosure of any such information as to 
the names and addresses of the Holders of Securities in accordance with the 
provisions of subsection (b) of this Section, 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 such subsection (b).


                                   -34-




          (d)  The Issuer shall upon written request to the Trustee (or, if 
applicable, the Security Registrar) be entitled to receive a list of the 
Holders of any and all series of Registered Securities.

          SECTION 4.3  REPORTS BY THE ISSUER.  The Issuer covenants:

          (a)  to file with the Trustee, within 15 days after the Issuer is
     required to file the same with the Commission, copies of the annual reports
     and of the information, documents and other reports (or copies of such
     portions of any of the foregoing as the Commission may from time to time by
     rules and regulations prescribe) which the Issuer may be required to file
     with the Commission pursuant to Section 13 or Section 15(d) of the Exchange
     Act; or if the Issuer is not required to file information, documents or
     reports pursuant to either of such Sections, then to 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 debt security listed and
     registered on a national securities exchange as may be prescribed from time
     to time in such rules and regulations;

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

          (c)  to transmit by mail to the Holders of Securities within 30 days
     after the filing thereof with the Trustee, in the manner and to the extent
     provided in Section 4.4(c), such summaries of any information, documents
     and reports required to be filed by the Issuer pursuant to subsections (a)
     and (b) of this Section as may be required to be transmitted to such
     Holders by rules and regulations prescribed from time to time by the
     Commission.

                                   -35-




          (i)  its eligibility under Section 6.9 and its qualification under
     Section 6.8, or in lieu thereof, if to the best of its knowledge it has
     continued to be eligible and qualified under such Sections, a written
     statement to such effect;

          (ii)  the character and amount of any advances (and if the Trustee
     elects so to state, the circumstances surrounding the making thereof) made
     by the Trustee (as such) which remain unpaid on the date of such report and
     for the reimbursement of which it claims or may claim a lien or charge,
     prior to that of the Securities of such series, on any property or funds
     held or collected by it as Trustee, except that the Trustee shall not be
     required (but may elect) to report such advances if such advances so
     remaining unpaid aggregate not more than 1/2 of 1% of the principal amount
     of the Securities of such series Outstanding on the date of such report;

          (iii)  the amount, interest rate and maturity date of all other
     indebtedness owing by the Issuer (or by any other obligor on the
     Securities) to the Trustee in its individual capacity on the date of such
     report, with a brief description of any property held as collateral
     security therefor, except any indebtedness based upon a creditor

     previously reported; and

          (vi)  any action taken by the Trustee in the performance of its duties
     under this Indenture which it has not previously reported and which in its
     opinion materially affects the Securities of such series, except action in
     respect of a default, notice of which has been or is to be withheld by it
     in accordance with the provisions of Section 5.11.

          (b)  The Trustee shall transmit to the Holders of each series, as 
provided in subsection (c) of this Section, a brief report with respect to

as such, since the date of the last report transmitted pursuant to the 
provisions of subsection (a) of this Section (or if no such report has yet 
been so transmitted, since the date of this 



                                   -36-




Indenture) for the reimbursement of which it claims or may claim a lien or 
charge, prior to that of the Securities of such series, on property or funds 
held or collected by it as Trustee and which it has not previously reported 
pursuant to this subsection (b), except that the Trustee shall not be 
required (but may elect) to report such advances if such advances remaining 
unpaid at any time aggregate 10% or less of the principal amount of the 
Securities of such series outstanding at such time, such report to be

     preceding such transmission, filed their names and addresses with the
     Trustee for that purpose; and

     each Holder of a Security whose name and address are preserved at the time
     by the Trustee as provided in Section 4.2(a).

          (d)  A copy of each such report shall, at the time of such
transmission to the Holders, be furnished to the Issuer and be filed by the

                     REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS
                                 ON EVENT OF DEFAULT            

          SECTION 5.1  EVENT OF DEFAULT DEFINED; ACCELERATION OF MATURITY; 
WAIVER OF DEFAULT.  "Event of Default" with respect to Securities of any 
series, wherever used herein, means each of the following events which shall 
have occurred and be continuing (whatever the reason for such Event of 
Default and whether it shall be voluntary or involuntary or be effected by 
operation of law or pursuant to any judgment, decree or order of any court or 
any order, rule or regulation of any administrative or governmental body):

          (a)  default in the payment of any installment of interest upon any of
     the Securities of such series as and when the same shall become due and
     payable, and continuance of such default for a period of 30 days; or

          (b)  default in the payment of all or any part of the principal of any
     of the Securities of such series as and when the same shall become due and
     payable, whether at maturity, upon any redemption, by declaration or
     otherwise; or

          (c)  default in the deposit of any sinking fund or analogous payment
     for the benefit of the Securities of such series as and when the same shall
     become due and payable;

          (d)  failure on the part of the Issuer duly to observe or perform any
     other of the covenants or agreements on the part of the Issuer in the
     Securities of such series or in this Indenture contained (other than a
     covenant or agreement expressly included herein solely for the benefit of
     Securities of other series) for a period of 90 days after the date on which
     written notice specifying such failure, stating that such notice is a
     "Notice of Default" hereunder and demanding that the Issuer remedy the
     same, shall have been given (i) (A) in person to the Chairman, the
     President, the Executive Vice President - Finance or the Treasurer of the
     Issuer promptly followed by notice by registered or certified mail, return
     receipt requested, by the Trustee, or (B) by registered or certified mail,
     return receipt requested, to the Issuer by the Trustee, or (ii) by
     registered or certified mail, return receipt requested, to the Issuer and
     the Trustee by the Holders of not less than 25% in aggregate principal
     amount of the Outstanding Securities of all series affected thereby; or


                                   -38-




          (e) (i)  a default occurs under any instrument (including this
     Indenture) under which there is at the time outstanding, or by which there
     may be secured or evidenced, any indebtedness of the Issuer for money
     borrowed by the Issuer (other than non-recourse indebtedness) which results
     in acceleration (whether by declaration or automatically) of, or the
     nonpayment at maturity (after giving effect to any applicable grace period)
     of, such indebtedness in an aggregate amount exceeding $30,000,000 or, if
     greater, 2% of Consolidated Capitalization, in which case the Issuer shall
     immediately give notice to the Trustee of such acceleration or non-payment
     and (ii) there shall have been a failure to cure such default or to
     discharge all such defaulted indebtedness within ten days after notice
     thereof to the Issuer by the Trustee or to the Issuer and the Trustee by
     the Holders of at least 25% in principal amount of the Securities then
     Outstanding (excluding, if such defaulted indebtedness includes any series
     of Securities, such series of Securities) and such acceleration shall not
     be rescinded or annulled; PROVIDED, HOWEVER, that it shall not constitute
     an Event of Default hereunder as long as the Issuer is contesting any such
     default or acceleration in good faith and by appropriate proceedings; or

          (f)  a court having jurisdiction in the premises shall enter a decree
     or order for relief in respect of the Issuer in an involuntary case under
     any applicable bankruptcy, insolvency or other similar law now or hereafter
     in effect, or appointing a receiver, liquidator, assignee, custodian,
     trustee or sequestrator (or similar official) of the Issuer or for any
     substantial part of the property of the Issuer, or ordering the winding up
     or liquidation of the affairs of the Issuer, and such decree or order shall
     remain unstayed and in effect for a period of 60 consecutive days; or

          (g)  the Issuer shall commence a voluntary case under any applicable
     bankruptcy, insolvency or other similar law now or hereafter in effect, or
     consent to the entry of an order for relief in an involuntary case under
     any such law, or consent to the appointment or taking possession by a
     receiver, liquidator, assignee, custodian, trustee or sequestrator (or
     similar official) of the Issuer or for any substantial part of the property
     of the Issuer, or make any general assignment for the benefit of creditors;
     or

          (h)  any other Event of Default provided in or pursuant to the
     supplemental indenture or Board Resolution establishing the terms of such
     series of 



                                   -39-




     Securities as provided in Section 2.3 or in the form of Security
     for such series.


If an Event of Default described in clause (a), (b) or (c) shall have 
occurred and be continuing with respect to the Securities of any series, 
then, and in each and every such case, unless the principal of all of the 
Securities of such series shall have already become due and payable, either 
the Trustee or the Holders of not less than 25% in aggregate principal amount 
of the Securities of such series then Outstanding, by notice in writing to 
the Issuer (and to the Trustee if given by such Holders), may declare the 
entire principal of all the Securities of such series then Outstanding and 
the interest accrued thereon to be due and payable immediately, and upon any 
such declaration the same shall become immediately due and payable.  If an 
Event of Default described in clause (d) or (h) (if the Event of Default 
under either clause is with respect to less than all series of the Securities 
then Outstanding) shall have occurred and be continuing with respect to the 
Securities of one or more series, then and in each and every such case, 
unless the principal of all of the Securities of such series shall have 
already become due and payable, either the Trustee or the Holders of not less 
than 25% in aggregate principal amount of the Securities of all series 
affected thereby then Outstanding (voting as one class), by notice in writing 
to the Issuer (and to the Trustee if given by such Holders), may declare the 
entire principal of all the Securities of all such affected series then 
Outstanding and the interest accrued thereon to be due and payable 
immediately, and upon any such declaration the same shall become immediately 
due and payable. If an Event of Default described in clause (d) or (h) (if 
the Event of Default under either clause is with respect to all series of 
Securities then Outstanding) or described in clause (e) shall have occurred 
and be continuing, then, and in each and every such case, unless the 
principal of all the Securities shall have already become due and payable, 
either the Trustee or the Holders of not less than 25% in aggregate principal 
amount of all the Securities then Outstanding (voting as one class), by 
notice in writing to the Issuer (and to the Trustee if given by such 
Holders), may declare the entire principal of all the Securities then 
Outstanding and interest accrued thereon, if any, to be due and payable 
immediately, and upon any such declaration the same shall become immediately 
due and payable.  If an Event of Default described in clause (f) or (g) shall 
have occurred and be continuing, the principal and interest on all the 
Securities then Outstanding shall thereby become and be immediately due and 
payable without any declaration or other act on the part of the Trustee or 
any Securityholders.

          The foregoing paragraph, however, is subject to the condition that 
if, at any time after the principal of the Securities of one or more series 
shall have been so declared due and payable, and before any judgment or 
decree for the payment of 


                                   -40-




the moneys due shall have been obtained or entered as hereinafter provided, 
the Issuer shall pay or shall deposit with the Trustee a sum sufficient to 
pay all matured installments of interest upon all the Securities of such 
series and the principal of all Securities of such series which shall have 
become due otherwise than by acceleration (with interest upon such principal 
and, to the extent that payment of such interest is enforceable under 
applicable law, on overdue installments of interest at the same rate as the 
rate of interest (or Yield to Maturity, in the case of Original Issue 
Discount Securities) specified in the Securities of such series, to the date 
of such payment or deposit) and such amount as shall be sufficient to cover 
reasonable compensation to the Trustee, its agents, attorneys and counsel, 
and all other expenses and liabilities incurred, and all advances made, by 
the Trustee except as a result of negligence or bad faith, and if any and all 
Events of Default under this Indenture with respect to such series, other 
than the non-payment of the principal of Securities of such series which 
shall have become due by acceleration, shall have been cured, waived or 
otherwise remedied as provided herein--then, and in every such case, the 
Holders of a majority in aggregate principal amount of all the Securities of 
such affected series then Outstanding (voting as one class, except in the 
case of Events of Default described in clauses (a), (b) and (c) of such 
paragraph, in which case each series of Securities as to which such an Event 
of Default shall have occurred shall vote as a separate class), by written 
notice to the Issuer and to the Trustee, may waive all defaults with respect 
to such series and rescind and annul such declaration and its consequences, 
but no such waiver or rescission and annulment shall extend to or shall 
affect any subsequent default or shall impair any right consequent thereon.

          For all purposes under this Indenture, if a portion of the 
principal of any Original Issue Discount Securities shall have been 
accelerated and declared due and payable pursuant to the provisions hereof, 
then, from and after such declaration, unless such declaration has been 
rescinded and annulled, the principal amount of such Original Issue Discount 
Securities shall be deemed, for all purposes hereunder, to be such portion of 
the principal thereof as shall be due and payable as a result of such 
acceleration, and payment of such portion of the principal thereof as shall 
be due and payable as a result of such acceleration, together with interest, 
if any, thereon and all other amounts owing thereunder, shall constitute 
payment in full of such Original Issue Discount Securities.

          SECTION 5.2  COLLECTION OF INDEBTEDNESS BY TRUSTEE; TRUSTEE MAY 
PROVE DEBT.  The Issuer covenants that (a) in case default shall be made in 
the payment of any installment of interest on any of the Securities of any 
series when such interest shall have become due and payable, and such default 
shall have continued for a period of 30 days, or (b) in case 


                                   -41-





default shall be made in the payment of all or any part of the principal of 
any of the Securities of any series when the same shall have become due and 
payable, whether at maturity, upon redemption, by declaration or otherwise -- 
then, upon demand of the Trustee, the Issuer will pay to the Trustee for the 
benefit of the Holders of the Securities of such series the whole amount that 
then shall have become due and payable on all Securities of such series, 
including all Coupons, for principal or interest, as the case may be (with 
interest to the date of such payment upon the overdue principal and, to the 
extent that payment of such interest is enforceable under applicable law, on 
overdue installments of interest at the same rate as the rate of interest (or 
Yield to Maturity, in the case of Original Issue Discount Securities) 
specified in the Securities of such series); and in addition thereto, such 
further amount as shall be sufficient to cover the costs and expenses of 
collection, including reasonable compensation to the Trustee, its agents, 
attorneys and counsel, and any expenses and liabilities incurred, and all 
advances made, by the Trustee except as a result of its negligence or bad 
faith.

          Until such demand is made by the Trustee, the Issuer may pay the 
principal of and interest on the Securities of such series to the Holders, 
whether or not the Securities of such series be overdue.

          In case the Issuer shall fail forthwith to pay such amounts upon 
such demand, the Trustee, in its own name and as trustee of an express trust, 
shall be entitled and empowered to institute any action or proceedings at law 
or in equity for the collection of the sums so due and unpaid, and may 
prosecute any such action or proceedings to judgment or final decree, and may 
enforce any such judgment or final decree against the Issuer or other obligor 
upon the Securities of such series and collect in the manner provided by law 
out of the property of the Issuer or other obligor upon the Securities of 
such series, wherever situated the moneys adjudged or decreed to be payable.

          In case there shall be pending proceedings relative to the Issuer 
or any other obligor upon the Securities of any series under Title 11 of the 
United States Code or any other applicable Federal or state bankruptcy, 
insolvency or other similar law, or in case a receiver, assignee or trustee 
in bankruptcy or reorganization, liquidator, sequestrator or similar official 
shall have been appointed for or taken possession of the Issuer or its 
property or such other obligor, or in case of any other comparable judicial 
proceedings relative to the Issuer or such other obligor, or to the creditors 
or property of the Issuer or such other obligor, the Trustee, irrespective of 
whether the principal of the Securities of any series shall then be due and 
payable as therein expressed or by declaration or otherwise and irrespective 
of whether the Trustee shall have made any demand 


                                   -42-





pursuant to the provisions of this Section, shall be entitled and empowered, 
by intervention in such proceedings or otherwise:

          (a)  to file and prove a claim or claims for the whole amount of the
     principal and interest (or, if the Securities of any series are Original
     Issue Discount Securities, such portion of the principal amount as may be
     specified in the terms of such series) owing and unpaid in respect of the
     Securities of each series, 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 reasonable compensation to the Trustee and its
     agents, attorneys and counsel, and for reimbursement of all expenses and
     liabilities incurred, and all advances made, by the Trustee, except as a
     result of negligence or bad faith) and of the Securityholders allowed in
     any judicial proceedings relative to the Issuer or such other obligor, or
     to the creditors or property of the Issuer or such other obligor,

          (b)  unless prohibited by applicable law and regulations, to vote on
     behalf of the Holders of the Securities of each series in any election of a
     trustee or a standby trustee in arrangement, reorganization, liquidation or
     other bankruptcy or insolvency proceedings or person performing similar
     functions in comparable proceedings, and

          (c)       to collect and receive any moneys or other property payable
     or deliverable on any such claims, and to distribute all amounts received
     with respect to the claims of the Securityholders and of the Trustee on
     their behalf; and any trustee, receiver, liquidator, custodian or other
     similar official is hereby authorized by each of the Securityholders to
     make payments to the Trustee, and, in the event that the Trustee shall
     consent to the making of payments directly to the Securityholders, to pay
     to the Trustee such amounts as shall be sufficient to cover reasonable
     compensation to the Trustee, and its agents, attorneys and counsel, and all
     other expenses and liabilities incurred, and all advances made, by the
     Trustee except as a result of negligence or bad faith.

          Nothing herein contained shall be deemed to authorize the Trustee 
to authorize or consent to or vote for or accept or adopt on behalf of any 
Holder any plan of reorganization, arrangement, adjustment or composition 
affecting the Securities of any series or the rights of any Holder thereof, 
or to authorize the Trustee to vote in respect of the claim of any 


                                   -43-




Holder in any such proceeding except, as aforesaid, to vote for the election 
of a trustee in bankruptcy or similar person.

          All rights of action and of asserting claims under this Indenture, 
or under any of the Securities of any series or Coupons appertaining thereto, 
may be enforced by the Trustee without the possession of any of the 
Securities of such series or coupons appertaining thereto or the production 
thereof on any trial or other proceedings relative thereto, and any such 
action or proceedings instituted by the Trustee shall be brought in its own 
name as trustee of an express trust, and any recovery of judgment, subject to 
the payment of the expenses, disbursements and compensation of the Trustee 
and its agents, attorneys and counsel, shall be for the ratable benefit of 
the Holders of the Securities or Coupons appertaining to such Securities in 
respect of which such action was taken.

          In any proceedings brought by the Trustee (and also any proceedings 
involving the interpretation of any provision of this Indenture to which the 
Trustee shall be a party) the Trustee shall be held to represent all the 
Holders of the Securities and Coupons appertaining thereto in respect to 
which action was taken, and it shall not be necessary to make any Holders of 
such Securities or Coupons parties to any such proceedings.

          SECTION 5.3  APPLICATION OF PROCEEDS.  Any moneys 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 moneys on account of 
principal or interest, upon presentation of the several Securities and 
Coupons appertaining thereto in respect of which moneys have been collected 
and stamping (or otherwise noting) thereon the payment, or issuing Securities 
of the same series in reduced principal amounts in exchange for the presented 
Securities if only partially paid, or upon surrender thereof if fully paid:

          FIRST:  To the payment of costs and expenses of collection applicable
     to such series, including reasonable compensation to the Trustee and its
     agents, attorneys and counsel and of all expenses and liabilities incurred,
     and all advances made, by the Trustee except as a result of negligence or
     bad faith;

          SECOND:  In case the principal of the Securities of such series in
     respect of which moneys have been collected shall not have become and be
     then due and payable, to the payment of interest on the Securities of such
     series in default in the order of the maturity of the installments of such
     interest, with interest (to the extent that such interest has been
     collected by the Trustee) upon the overdue installments of interest at 


                                   -44-




     the same rate as the rate of interest (or Yield to Maturity, in the case of
     Original Issue Discount Securities) specified in such Securities, such
     payments to be made ratably to the Persons entitled thereto, without
     discrimination or preference;

          THIRD:  In case the principal of the Securities of such series in
     respect of which moneys have been collected shall have become and be then
     due and payable, to the payment of the whole amount then owing and unpaid
     upon all the Securities of such series for principal and interest, with
     interest upon the overdue principal, and (to the extent that such interest
     has been collected by the Trustee) upon overdue installments of interest at
     the same rate as the rate of interest (or Yield to Maturity, in the case of
     Original Issue Discount Securities) specified in the Securities of such
     series; and in case such moneys shall be insufficient to pay in full the
     whole amount so due and unpaid upon the Securities of such series, then to
     the payment of such principal and interest, without preference or priority
     of principal over interest, or of interest over principal, or of any
     installment of interest over any other installment of interest, or of any
     Security of such series over any other Security of such series, ratably to
     the aggregate of such principal and accrued and unpaid interest; and

          FOURTH:  To the payment of the remainder, if any, to the Issuer or any
     other person lawfully entitled thereto.

          SECTION 5.4  SUITS FOR ENFORCEMENT.  In case an Event of Default 
has occurred, has not been waived and is continuing, the Trustee may in its 
discretion proceed to protect and enforce the rights vested in it by this 
Indenture by such appropriate judicial proceedings as the Trustee shall deem 
most effectual to protect and enforce any of such rights, either at law or in 
equity or in bankruptcy or otherwise, whether for the specific enforcement of 
any covenant or agreement contained in this Indenture or in aid of the 
exercise of any power granted in this Indenture or to enforce any other legal 
or equitable right vested in the Trustee by this Indenture or by law.

          SECTION 5.5  RESTORATION OF RIGHTS ON ABANDONMENT OF PROCEEDINGS.  
In case the Trustee shall have proceeded to enforce any right under this 
Indenture and such proceedings shall have been discontinued or abandoned for 
any reason, or shall have been determined adversely to the Trustee, then, and 
in every such case, the Issuer and the Trustee shall be restored respectively 
to their former positions and rights hereunder, and all rights, remedies and 
powers of the Issuer, the Trustee and the 


                                   -45-





Securityholders shall continue as though no such proceedings had been taken.

          SECTION 5.6  LIMITATIONS ON SUITS BY SECURITYHOLDERS.  No Holder of 
any Security of any series or of any Coupon appertaining thereto shall have 
any right by virtue or by availing of any provision of this Indenture to 
institute any action or proceeding at law or in equity or in bankruptcy or 
otherwise upon or under or with respect to this Indenture, or for the 
appointment of a trustee, receiver, liquidator, custodian or other similar 
official or for any other remedy hereunder, unless such Holder previously 
shall have given to the Trustee written notice of default and of the 
continuance thereof, as hereinbefore provided, and unless also the Holders of 
not less than 25% in aggregate principal amount of the Securities of each 
affected series then Outstanding (determined as provided in Section 5.1 and 
voting as one class) shall have made written request upon the Trustee to 
institute such action or proceedings in its own name as trustee hereunder and 
shall have offered to the Trustee such reasonable indemnity as it may require 
against the costs, expenses and liabilities to be incurred therein or thereby 
and the Trustee for 60 days after its receipt of such notice, request and 
offer of indemnity shall have failed to institute any such action or 
proceeding and no direction inconsistent with such written request shall have 
been given to the Trustee pursuant to Section 5.9; it being understood and 
intended, and being expressly covenanted by the taker and Holder of every 
Security or Coupon with every other taker and Holder and the Trustee, that no 
one or more Holders of Securities of any series or Coupons appertaining 
thereto shall have any right in any manner whatever by virtue or by availing 
of any provision of this Indenture to affect, disturb or prejudice the rights 
of any other Holder of Securities or Coupons appertaining thereto, or to 
obtain or seek to obtain priority over or preference to any other such Holder 
or to enforce any right under this Indenture, except in the manner herein 
provided and for the equal, ratable and common benefit of all Holders of 
Securities of the affected series and Coupons.  For the protection and 
enforcement of the provisions of this Section, each and every Securityholder 
and the Trustee shall be entitled to such relief as can be given either at 
law or in equity.

          SECTION 5.7  UNCONDITIONAL RIGHT OF SECURITYHOLDERS TO INSTITUTE 
CERTAIN SUITS.  Notwithstanding any other provision in this Indenture and any 
provision of any Security, the right of any Holder of any Security or Coupon 
to receive payment of the principal of and interest on such Security or 
Coupon on or after the respective due dates expressed in such Security or 
Coupon, or to institute suit for the enforcement of any such payment on or 
after such respective dates, shall not be impaired or affected without the 
consent of such Holder.


                                   -46-




          SECTION 5.8  POWERS AND REMEDIES CUMULATIVE; DELAY OR OMISSION NOT 
WAIVER OF DEFAULT.  Except as provided in the last sentence of Section 2.9 
and subject to Section 5.6, no right or remedy herein conferred upon or 
reserved to the Trustee or to the Holders of Securities or Coupons is 
intended to be exclusive of any other right or remedy, and every right and 
remedy shall, to the extent permitted by law, be cumulative and in addition 
to every other right and remedy given hereunder or now or hereafter existing 
at law or in 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.

          No delay or omission of the Trustee or of any Holder of Securities 
or Coupons to exercise any right or power accruing upon any Event of Default 
occurring and continuing as aforesaid shall impair any such right or power or 
shall be construed to be a waiver of any such Event of Default or an 
acquiescence therein; and, subject to Section 5.6, every power and remedy 
given by this Indenture or by law to the Trustee or to the Holders of 
Securities or Coupons may be exercised from time to time, and as often as 
shall be deemed expedient, by the Trustee or by the Holders of Securities or 
Coupons.

          SECTION 5.9  CONTROL BY HOLDERS OF SECURITIES.  The Holders of a 
majority in aggregate principal amount of the Securities of each series 
affected at the time Outstanding (determined as provided in Section 5.1 and 
voting as one class) 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 upon the Trustee with respect to 
the Securities of such affected series by this Indenture; PROVIDED that such 
direction shall not be otherwise than in accordance with law and the 
provisions of this Indenture and PROVIDED FURTHER that (subject to the 
provisions of Section 6.1) the Trustee shall have the right to decline to 
follow any such direction if the Trustee, being advised by counsel, shall 
determine that the action or proceeding so directed may not lawfully be taken 
or if the Trustee in good faith by its board of directors, its executive 
committee or a trust committee of directors or Responsible Officers of the 
Trustee shall determine that the action or proceedings so directed would 
involve the Trustee in personal liability or that the actions or forbearances 
specified in or pursuant to such direction would be unduly prejudicial to the 
interests of Holders of the Securities of all affected series not joining in 
the giving of said direction, it being understood that (subject to Section 
6.1) the Trustee shall have no duty to ascertain whether or not such actions 
or forbearances are unduly prejudicial to such Holders.


                                   -47-




          Nothing in this Indenture shall impair the right of the Trustee in 
its discretion to take any action deemed proper by the Trustee and which is 
not inconsistent with such direction or directions by Securityholders.

          SECTION 5.10  WAIVER OF PAST DEFAULTS.  Prior to the declaration of 
acceleration of the maturity of any Securities as provided in Section 5.1, 
the Holders of a majority in aggregate principal amount of the Securities of 
all series at the time Outstanding with respect to which a default or an 
Event of Default shall have occurred and be continuing (determined as 
provided in Section 5.1 and voting as one class) may on behalf of the Holders 
of all such affected Securities waive any past default or Event of Default 
with respect to such series described in Section 5.1 and its consequences, 
except a default or an Event of Default in respect of a covenant or provision 
hereof or of any Security which cannot be modified or amended without the 
consent of the Holder of each Security affected.  In the case of any such 
waiver, the Issuer, the Trustee and the Holders of all such affected 
Securities shall be restored to their former positions and rights hereunder, 
respectively; but no such waiver shall extend to any subsequent or other 
default or impair any right consequent thereon.

          Upon any such waiver, such default shall cease to exist and be 
deemed to have been cured and not to have occurred, and any Event of Default 
arising therefrom shall be deemed to have been cured, and not to have 
occurred for every purpose of this Indenture; but no such waiver shall extend 
to any subsequent or other default or Event of Default or impair any right 
consequent thereon.

          SECTION 5.11  TRUSTEE TO GIVE NOTICE OF DEFAULT, BUT MAY WITHHOLD 
IN CERTAIN CIRCUMSTANCES.  The Trustee shall, within 90 days after the 
occurrence of a default with respect to the Securities of any series, give 
notice of all defaults with respect to such series known to the Trustee (i) 
if any Unregistered Securities of such series are then Outstanding, to the 
Holders thereof by publication at least once in each Authorized Newspaper 
with respect to such series and (ii) to all Holders of Securities of such 
series in the manner and to the extent provided in Section 4.4(c), unless in 
each case such defaults shall have been cured before the mailing or 
publication of such notice (the term "default" for the purpose of this 
Article being hereby defined to mean any event or condition which is, or with 
notice or lapse of time or both would become, an Event of Default); provided 
that, except in the case of default in the payment of the principal of or the 
interest on any of the Securities of such series, or in the payment of any 
sinking fund installment or analogous payment on such series, the Trustee 
shall be protected in withholding such notice if and so long as the board of 
directors, the executive committee or a trust 


                                   -48-






committee of directors or trustees and/or Responsible Officers of the Trustee 
in good faith determines that the withholding of such notice is in the 
interests of the Securityholders of such series.

          SECTION 5.12  RIGHT OF COURT TO REQUIRE FILING OF UNDERTAKING TO 
PAY COSTS.  All parties to this Indenture agree, and each Holder of any 
Security or Coupon 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 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 Trustee, to any suit instituted 
by any Securityholder or group of Securityholders of any series holding in 
the aggregate more than 10% in aggregate principal amount of the Securities 
of such series, or, in the case of any suit relating to or arising under 
clause (d) or (g) of Section 5.1 (if the suit relates to the Securities of 
more than one but less than all series), 10% in aggregate principal amount of 
the Securities then outstanding and affected thereby, or, in the case of any 
suit relating to or arising under clause (d) or (g) (if the suit relates to 
all the Securities then Outstanding), or clause (e) or (f) of Section 5.1, 
10% in aggregate principal amount of all Securities then Outstanding, or to 
any suit instituted by any Securityholder for the enforcement of the payment 
of the principal of or the interest (including interest evidenced by any 
Coupon) on any Security on or after the due date expressed in such Security 
or Coupon or any date fixed for redemption.

                                     ARTICLE SIX

                                CONCERNING THE TRUSTEE

          SECTION 6.1  DUTIES AND RESPONSIBILITIES OF THE TRUSTEE; DURING
DEFAULT; PRIOR TO DEFAULT.  The Trustee, prior to the occurrence of an Event of
Default with respect to the Securities of a particular series and after the
curing or waiving of all Events of Default which may have occurred with respect
to such series, undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture.  In case an Event of Default with
respect to the Securities of a particular series has occurred (which has not
been cured or waived), the Trustee shall exercise with respect to such series
such of the rights and powers vested in it by this Indenture, and use the same
degree of care and skill in their exercise, as a 


                                   -49-





prudent man would exercise or use under the circumstances in the conduct of 
his own affairs.

          No provision of this Indenture shall be construed to relieve the 
Trustee from liability for its own negligent action, its own negligent 
failure to act or its own wilful misconduct, except that

          (a)  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 with
     respect to such series:

               (i)  the duties and obligations of the Trustee with respect to
          the Securities of such series shall be determined solely by the
          express provisions of this Indenture, and the Trustee shall not be
          liable except for the performance of such duties and obligations as
          are specifically set forth in this Indenture, and no implied covenants
          or obligations shall be read into this Indenture against the Trustee;
          and

               (ii)  in the absence of bad faith on the part of the Trustee, the
          Trustee may conclusively rely, as to the truth of the statements and
          the correctness of the opinions expressed therein, upon any
          statements, certificates or opinions furnished to the Trustee and
          conforming to the requirements of this Indenture; but in the case of
          any such statements, certificates or opinions which by any provision
          hereof are specifically required to be furnished to the Trustee, the
          Trustee shall be under a duty to examine the same to determine whether
          or not they conform to the requirements of this Indenture;

          (b)  the Trustee shall not be liable for any error of judgment made in
     good faith by a Responsible Officer or Responsible Officers of the Trustee,
     unless it shall be proved that the Trustee was negligent in ascertaining
     the pertinent facts; and

          (c)  the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with an
     appropriate direction of the Holders pursuant to Section 5.9 relating to
     the time, method and place of conducting any proceeding for any remedy
     available to the Trustee, or exercising any 


                                   -50-



     trust or power conferred upon the Trustee, under this Indenture.


          None of the provisions contained in this indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there shall be reasonable grounds for believing that
the repayment of such funds or adequate indemnity against such liability is not
reasonably assured to it.

          SECTION 6.2  CERTAIN RIGHTS OF THE TRUSTEE.  Subject to Section 6.1:

          (a)  the Trustee may rely and shall be protected in acting or
     refraining from acting upon any resolution, Officers' Certificate or other
     certificate, statement, instrument, opinion, report, notice, request,
     consent, order, bond, debenture, note, Coupon, security 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, direction, order or demand of the Issuer mentioned
     herein shall be sufficiently evidenced by an Officers' Certificate (unless
     other evidence in respect thereof be herein specifically prescribed); and
     any resolution of the Board of Directors may be evidenced to the Trustee by
     a copy thereof certified by the secretary or an assistant secretary of the
     Issuer;

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

          (d)  the Trustee shall be under no obligation to exercise any of the
     trusts or powers vested in it by this Indenture at the request, order or
     direction of any of the Holders pursuant to the provisions of this
     Indenture, unless such Holders shall have offered to the Trustee reasonable
     indemnity against the costs, expenses and liabilities which might be
     incurred therein or thereby;

          (e)  the Trustee shall not be liable for any action taken or omitted
     by it in good faith and believed by it to be authorized or within the


                                   -51-



     discretion, rights or powers conferred upon it by this Indenture;

          (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, 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, consent, order, approval,
     appraisal, bond, debenture, note, Coupon, security or other paper or
     document unless requested in writing so to do by the Holders of not less
     than a majority in aggregate principal amount of the Securities of all
     affected series then Outstanding; PROVIDED 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, in the opinion
     of the Trustee, not 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 proceeding; the reasonable expenses of every such
     investigation shall be paid by the Issuer or, if paid by the Trustee, shall
     be repaid by the Issuer upon demand; and

          (g)  the Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or by or through agents or
     attorneys not regularly in its employ, and the Trustee shall not be
     responsible for any misconduct or negligence on the part of any such agent
     or attorney appointed with due care by it hereunder.

          SECTION 6.3  TRUSTEE NOT RESPONSIBLE FOR RECITALS, DISPOSITION OF 
SECURITIES OR APPLICATION OF PROCEEDS THEREOF.  The recitals contained herein 
and in the Securities, except the Trustee's certificates of authentication, 
shall be taken as the statements of the Issuer, and the Trustee assumes no 
responsibility for the correctness of the same.  The Trustee makes no 
representation as to the validity or sufficiency of this Indenture or of the 
Securities or Coupons.  The Trustee shall not be accountable for the use or 
application by the Issuer of any of the Securities or of the proceeds thereof.

          SECTION 6.4  TRUSTEE AND AGENTS MAY HOLD SECURITIES OR COUPONS; 
COLLECTIONS, ETC. The Trustee or any agent of the Issuer or the Trustee, in 
its individual or any other capacity, may become the owner or pledgee of 
Securities or Coupons with the same rights it would have if it were not the 
Trustee or such 


                                   -52-



agent and, subject to Sections 6.8 and 6.13, may otherwise deal with the 
Issuer and receive, collect, hold and retain collections from the Issuer with 
the same rights it would have if it were not the Trustee or such agent.

          SECTION 6.5  MONEYS HELD BY TRUSTEE.  Subject to the provisions of 
Section 10.4, all moneys received by the Trustee shall, until used or applied 
as herein provided, be held in trust for the purposes for which they were 
received, but need not be segregated from other funds except to the extent 
required by mandatory provisions of law.  Neither the Trustee nor any agent 
of the Issuer or the Trustee shall be under any liability for interest on any 
moneys received by it hereunder.

          SECTION 6.6  COMPENSATION AND INDEMNIFICATION OF TRUSTEE AND ITS 
PRIOR CLAIM.  The Issuer covenants and agrees to pay to the Trustee from time 
to time, and the Trustee shall be entitled to, reasonable compensation (which 
shall not be limited by any provision of law in regard to the compensation of 
a trustee of an express trust), and the Issuer covenants and agrees to pay or 
reimburse the Trustee upon its request for all reasonable expenses, 
disbursements and advances incurred or made by or on behalf of it in 
accordance with any of the provisions of this Indenture (including the 
reasonable compensation and the expenses and disbursements of its counsel and 
of all agents and other persons not regularly in its employ) except any such 
expense, disbursement or advance as may arise from its negligence or bad 
faith.  The Issuer also covenants to indemnify the Trustee for, and to hold 
it harmless against, any loss, liability or expense incurred without 
negligence or bad faith on its part arising out of or in connection with the 
acceptance or administration of this Indenture or the trusts hereunder and 
its duties hereunder, including the costs and expenses of defending itself 
against or investigating any claim or liability in the premises.  The 
obligations of the Issuer under this Section to compensate and indemnify the 
Trustee and to pay or reimburse the Trustee for expenses, disbursements and 
advances shall constitute additional indebtedness hereunder and shall survive 
the satisfaction and discharge of this Indenture.  Such additional 
indebtedness shall be a senior claim to that of the Securities upon all 
property and funds held or collected by the Trustee as such, except funds 
held in trust for the benefit of the Holders of particular Securities or 
Coupons, and the Securities are hereby subordinated to such senior claim.

          SECTION 6.7  RIGHT OF TRUSTEE TO RELY ON OFFICERS' CERTIFICATE, 
ETC. Subject to Sections 6.1 and 6.2, whenever in the administration of the 
trusts of this Indenture the Trustee shall deem it necessary or desirable 
that a matter be proved or established prior to taking or suffering or 
omitting any action hereunder, such matter (unless other evidence in respect 
thereof be herein specifically prescribed) may, in the absence of 


                                   -53-



negligence or bad faith on the part of the Trustee, be deemed to be 
conclusively proved and established by an Officers' Certificate delivered to 
the Trustee, and such certificate, in the absence of negligence or bad faith 
on the part of the Trustee, shall be full warrant to the Trustee for any 
action taken, suffered or omitted by it under the provisions of this 
Indenture in reliance thereon.

          SECTION 6.8  QUALIFICATION OF TRUSTEE; 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 6.9  PERSONS ELIGIBLE FOR APPOINTMENT AS TRUSTEE.  There 
shall at all times be a Trustee hereunder for each series of Securities which 
shall be a corporation organized and doing business under the laws of the 
United States of America or of any State thereof or the District of Columbia 
having a combined capital and surplus of at least $50,000,000, and which is 
authorized under such laws to exercise corporate trust powers and is subject 
to supervision or examination by Federal, State or District of Columbia 
authority.  If such corporation publishes reports of condition at least 
annually, pursuant to law or to the requirements of the aforesaid 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.  In case at any time the Trustee shall cease to be eligible in 
accordance with the provisions of this Section, the Trustee shall resign 
immediately in the manner and with the effect specified in Section 6.10.

          SECTION 6.10  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR 
TRUSTEE. (a) The Trustee, or any trustee or trustees hereafter appointed, may 
at any time resign with respect to one or more or all series of Securities by 
giving written notice of resignation to the Issuer and (i) if any 
Unregistered Securities of a series affected are then Outstanding, by giving 
notice of such resignation to the Holders thereof by publication at least 
once in each Authorized Newspaper with respect to such series, (ii) if any 
Unregistered Securities of a series affected are then Outstanding, by mailing 
notice of such resignation to the Holders thereof who have filed their names 
and addresses with the Trustee pursuant to Section 4.4(c)(ii) at such 
addresses as were so furnished to the Trustee and (iii) by mailing notice of 
such resignation to the Holders of the then Outstanding Registered Securities 
of each series affected at their addresses as they shall appear on the 
Security Register.  Upon receiving such notice of resignation, the Issuer 
shall promptly appoint a 


                                   -54-




successor trustee or trustees with respect to the applicable series by 
written instrument, in duplicate, executed by authority of the Board of 
Directors, one copy of which instrument shall be delivered to the resigning 
Trustee and one copy to the successor trustee or trustees.  If no successor 
trustee shall have been so appointed with respect to any series and shall 
have accepted appointment within 30 days after the mailing of such notice of 
resignation, the resigning trustee may petition any court of competent 
jurisdiction for the appointment of a successor trustee, or any Holder who 
has been a bona fide Holder of a Security or Securities of such series for at 
least six months may, subject to the provisions of Section 5.12, on behalf of 
such Holder and all others similarly situated, petition any such court for 
the appointment of a successor trustee.  Such court may thereupon, after such 
notice, if any, as it may deem proper and prescribe, appoint a successor 
trustee.

           (b)  In case at any time any of the following shall
occur:

           (i) the Trustee shall fail to comply with the provisions of Section
     6.8 with respect to any series of Securities after written request therefor
     by the Issuer or by any Holder who has been a bona fide Holder of a
     Security or Securities of such series for at least six months; or

          (ii)  the Trustee shall cease to be eligible in accordance with the
     provisions of Section 6.9 and shall fail to resign after written request
     therefor by the Issuer or by any such Holder; or

          (iii) the Trustee shall become incapable of acting or shall be
     adjudged a bankrupt or insolvent, or a receiver or liquidator 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; or

           (iv)  the Issuer shall elect to remove the Trustee, provided that no
     Event of Default, or event which following notice or the passage of time or
     both would constitute an Event of Default, shall then exist with respect to
     the Securities or series thereof as to which the Trustee shall be removed
     and such removal does not adversely affect the interests of any Holder of
     such Securities or series;

then, in any such case, the Issuer may remove the Trustee with respect to the
Securities of any or all series, as appropriate, and appoint a successor trustee
for such series by written 


                                   -55-




instrument, in duplicate, executed by order of the Board of Directors, one 
copy of which instrument shall be delivered to the Trustee so removed and one 
copy to the successor trustee or trustees, or, subject to the provisions of 
Section 5.12, any Holder who has been a bona fide Holder of a Security or 
Securities of such series for at least six months may, on behalf of such 
Holder and all others similarly situated, petition any court of competent 
jurisdiction for the removal of the Trustee and the appointment of a 
successor trustee.  Such court may thereupon, after such notice, if any, as 
it may deem proper and prescribe, remove the Trustee and appoint a successor 
trustee.

          (c)  Any resignation or removal of the Trustee with respect to any 
series of Securities and any appointment of a successor trustee with respect 
to such series pursuant to any of the provisions of this Section shall become 
effective upon acceptance of appointment by the successor trustee as provided 
in Section 6.11.

          SECTION 6.11  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR TRUSTEE.  Any 
successor trustee appointed as provided in Section 6.10 shall execute, 
acknowledge and deliver to the Issuer and to its predecessor trustee an 
instrument accepting such appointment hereunder, and thereupon the 
resignation or removal of the predecessor trustee with respect to all 
applicable series of Securities shall become effective and such successor 
trustee, without any further act, deed or conveyance, shall become vested 
with all rights, powers, trusts and duties with respect to such applicable 
series of its predecessor hereunder, with like effect as if originally named 
as trustee for such series hereunder; but, nevertheless, on the written 
request of the Issuer or of the successor trustee, upon payment of its 
charges then unpaid, the trustee ceasing to act shall, subject to Section 
10.4, pay over to the successor trustee all moneys at the time held by it 
hereunder for the benefit of such applicable series and shall execute, 
acknowledge and deliver an instrument transferring to such successor trustee 
all such rights, powers, trusts and duties.  Upon request of any such 
successor trustee, the Issuer shall execute and acknowledge any and all 
instruments in writing for more fully and certainly vesting in and confirming 
to such successor trustee all such rights, powers and trusts.  Any trustee 
ceasing to act shall, nevertheless, retain a prior claim upon all property or 
funds held or collected by such trustee for the benefit of such applicable 
series to secure any amounts then due it pursuant to the provisions of 
Section 6.6.

          If a successor trustee is appointed with respect to the Securities 
of one or more (but less than all) series, the Issuer, the predecessor 
trustee and each successor trustee so appointed shall execute, acknowledge 
and deliver an indenture supplemental hereto which shall contain such 
provisions as shall be deemed necessary or desirable to confirm that all the 
rights, powers, 

                                   -56-



trusts and duties of such predecessor trustee with respect to the Securities 
of any series as to which such predecessor trustee is not retiring shall 
continue to be vested in such predecessor trustee, and to add to or change 
any of the provisions of this Indenture as shall be necessary to provide for 
or facilitate the administration of the trusts hereunder by more than one 
trustee, it being understood that nothing herein or in such supplemental 
indenture shall constitute such trustees as co-trustees of the same trust and 
that each such trustee shall be trustee of a separate trust or trusts under 
this indenture.  

          No successor trustee with respect to any series of Securities shall 
accept appointment as provided in this Section unless at the time of such 
acceptance such successor trustee shall be qualified under the provisions of 
Section 6.8 and eligible under the provisions of Section 6.9.  

          Upon acceptance of appointment by any successor trustee as provided 
in this Section, the Issuer shall give notice thereof (a) if any Unregistered 
Securities of a series affected are then Outstanding, to the Holders thereof 
by publication of such notice at least once in each Authorized Newspaper with 
respect to such series, (b) if any Unregistered Securities of a series 
affected are then Outstanding, to the Holders thereof who have filed their 
names and addresses with the Trustee pursuant to Section 4.4(c)(ii) by 
mailing such notice to such Holders at such addresses as were so furnished to 
the Trustee (and the Trustee shall make such information available to the 
Issuer for such purpose) and (c) to the Holders of Registered Securities of 
each series affected, by mailing such notice to such Holders at their 
addresses as they shall appear on the Security Register.  If the acceptance 
of appointment is substantially contemporaneous with the resignation, then 
the notice called for by the preceding sentence may be combined with the 
notice called for by Section 6.10. If the Issuer fails to give such notice 
within 10 days after acceptance of appointment by the successor trustee, the 
successor trustee shall cause such notice to be given at the expense of the 
Issuer.  

          SECTION 6.12  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO 
BUSINESS OF TRUSTEE.  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 the corporate trust business of the 
Trustee, shall be the successor of the Trustee hereunder, PROVIDED that such 
corporation shall be qualified under the provisions of Section 6.8 and 
eligible under the provisions of Section 6.9, without the execution or filing 
of any paper or any further act on the part of any of the parties hereto, 
anything herein to the contrary notwithstanding.  


                                   -57-




          In case at the time of such succession to the Trustee any of the 
Securities of any series shall have been authenticated but not delivered, any 
such successor trustee may adopt the certificate of authentication of any 
predecessor trustee and deliver the Securities so authenticated; and, in case 
at that time any of the Securities of any series shall not have been 
authenticated, any successor trustee may authenticate such Securities either 
in the name of any predecessor hereunder or in the name of such successor 
trustee; and in all such cases such certificate of authentication shall have 
the full force which it is anywhere in the Securities of such series or in 
this Indenture provided that the certificate of authentication of the Trustee 
shall have; PROVIDED that the right to adopt the certification of any 
predecessor trustee or to authenticate Securities of any series in the name 
of any predecessor trustee shall apply only to its successor or successors by 
merger, conversion or consolidation.  

          SECTION 6.13  PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE ISSUER. 
(a) Subject to the provisions of this Section, if the Trustee shall be or 
shall become a creditor, directly or indirectly, secured or unsecured, of the 
Issuer within four months prior to a default, as defined in subsection (c) of 
this Section, or subsequent to such a default, then, unless and until such 
default shall be cured, the Trustee shall set apart and hold in a special 
account for the benefit of the Trustee individually, the Holders of the 
Securities and Coupons and the holders of other indenture securities (as 
defined in such subsection (c)):

          (1)  an amount equal to any and all reductions in the amount due and
     owing upon any claim as such creditor in respect of principal or interest
     affected after the beginning of such four months' period and valid as
     against the Issuer and its other creditors, except any such reduction
     resulting from the receipt or disposition of any property described in
     clause (2) of this subsection, or from the exercise of any right of set-off
     which the Trustee could have exercised if a petition in bankruptcy had been
     filed by or against the Issuer upon the date of such default; and 

          (2)  all property received by the Trustee in respect of any claim as
     such creditor, either as security therefor, or in satisfaction or
     composition thereof, or otherwise, after the beginning of such four months'
     period, or an amount equal to the proceeds of any such property if disposed
     of, subject, however, to the rights, if any, of the Issuer and its other
     creditors in such property or such proceeds.  

          Nothing herein contained, however, shall affect the right of the
Trustee: 


                                   -58-




          (A)  to retain for its own account (i) payments made on account of any
     such claim by any person (other than the Issuer) who is liable thereon,
     (ii) the proceeds of the bona fide sale of any such claim by the Trustee to
     a third person, and (iii) distributions made in cash, securities or other
     property in respect of claims filed against the Issuer in bankruptcy or
     receivership or in proceedings for reorganization pursuant to Title 11 of
     the United States Code or applicable state law;

          (B)  to realize, for its own account, upon any property held by it as
     security for any such claim, if such property was so held prior to the
     beginning of such four months' period;

          (C)  to realize, for its own account, but only to the extent of the
     claim hereinafter mentioned, upon any property held by it as security for
     any such claim, if such claim was created after the beginning of such four
     months' period and such property was received as security therefor
     simultaneously with the creation thereof, and if the Trustee shall sustain
     the burden of proving that at the time such property was so received the
     Trustee had no reasonable cause to believe that a default as defined in
     subsection (c) of this Section would occur within four months; or

          (D)  to receive payment on any claim referred to in clause (B) or (C)
     of this subsection, against the release of any property held as security
     for such claim as provided in such clause (B) or (C), as the case may be,
     to the extent of the fair value of such property,

          For the purposes of clauses (B), (C) and (D), property substituted 
after the beginning of such four months period for property held as security 
at the time of such substitution shall, to the extent of the fair value of 
the property released, have the same status as the property released, and, to 
the extent that any claim referred to in any of such clauses is created in 
renewal of or in substitution for or for the purpose of repaying or refunding 
any pre-existing claim of the Trustee as such creditor, such claim shall have 
the same status as such pre-existing claim.  

          If the Trustee shall be required to account, the funds and property 
held in such special account and the proceeds thereof shall be apportioned 
among the Trustee, the Holders and the holders of other indenture securities 
in such manner that the Trustee, the Holders and the holders of other 
indenture securities realize, as a result of payments from such special 
account and payments of dividends on claims filed against the Issuer in 
bankruptcy or receivership or in proceedings for reorganization pursuant to 
Title 11 of the United States Code or 


                                   -59-



applicable State law, the same percentage of their respective claims, figured 
before crediting to the claim of the Trustee anything on account of the 
receipt by it from the Issuer of the funds and property in such special 
account and before crediting to the respective claims of the Trustee, the 
Holders and the holders of other indenture securities dividends on claims 
filed against the Issuer in bankruptcy or receivership or in proceedings for 
reorganization pursuant to Title 11 of the United States Code or applicable 
State law, but after crediting thereon receipts on account of the 
indebtedness represented by their respective claims from all sources other 
than from such dividends and from the funds and property so held in such 
special account.  As used in this paragraph with respect to any claim, the 
term "dividends" shall include any distribution with respect to such claim, 
in bankruptcy or receivership or in proceedings for reorganization pursuant 
to Title 11 of the United States Code or applicable State law, whether such 
distribution is made in cash, securities or other property, but shall not 
include any such distribution with respect to the secured portion, if any, of 
such claim.  The court in which such bankruptcy, receivership or proceeding 
for reorganization is pending shall have jurisdiction (i) to apportion among 
the Trustee, the Holders and the holders of other indenture securities, in 
accordance with the provisions of this paragraph, the funds and property held 
in such special account and the proceeds thereof, or (ii) in lieu of such 
apportionment, in whole or in part, to give to the provisions of this 
paragraph due consideration in determining the fairness of the distributions 
to be made to the Trustee, the Holders and the holders of other indenture 
securities with respect to their respective claims, in which event it shall 
not be necessary to liquidate or to appraise the value of any securities or 
other property held in such special account or as security for any such 
claim, or to make a specific allocation of such distributions as between the 
secured and unsecured portions of such claims, or otherwise to apply the 
provisions of this paragraph as a mathematical formula.  

          Any Trustee who has resigned or been removed after the beginning of 
such four-months' period shall be subject to the provisions of this 
subsection as though such resignation or removal had not occurred.  If any 
Trustee has resigned or been removed prior to the beginning of such 
four-months' period, it shall be subject to the provisions of this subsection 
if and only if the following conditions exist: 

          (i)  the receipt of property or reduction of claim which would have
     given rise to the obligation to account, if such Trustee had continued as
     trustee, occurred after the beginning of such four-months' period; and

                                   -60-




          (ii) such receipt of property or reduction of claim occurred within
     four months after such resignation or removal.  

          (b)  There shall be excluded from the operation of this Section a
     creditor relationship arising from:

               (1)  ownership or acquisition of securities issued under any
     indenture or any security or securities having a maturity of one year or
     more at the time of acquisition by the Trustee;

               (2)  advances authorized by a receivership or bankruptcy court of
     competent jurisdiction or by this indenture for the purpose of preserving
     any property which shall at anytime be subject to the lien of this
     Indenture or of discharging tax liens or other prior liens or encumbrances
     thereon, if notice of such advance and of the circumstances surrounding the
     making thereof is given to the Securityholders at the time and in the
     manner provided in this Indenture; 

               (3)  disbursements made in the ordinary course of business in the
     capacity of trustee under an indenture,  transfer agent, registrar,
     custodian, paying agent, fiscal agent or depositary, or other similar
     capacity; 

               (4)  an indebtedness created as a result of services rendered or
     premises rented or an indebtedness created as a result of goods or
     securities sold in a cash transaction as defined in subsection (c)(3) of
     this Section;

               (5)  the ownership of stock or of other securities of a
     corporation organized under the provisions of Section 25(a) of the Federal
     Reserve Act, as amended, which is directly or indirectly a creditor of the
     Issuer; or

               (6)  the acquisition, ownership, acceptance or negotiation of any
     drafts, bills of exchange, acceptances or obligations which fall within the
     classification of self-liquidating paper as defined in subsection (c)(4) of
     this Section.  

          (c)  As used in this Section: 

               (1)  the term "default" shall mean any failure to
     make payment in full of the principal of or interest upon any of the
     Securities or upon the other indenture securities when and as such
     principal or interest becomes due and payable; 

                                   -61-




               (2)  the term "other indenture securities" shall mean securities
     upon which the Issuer is an obligor (as defined in the Trust Indenture Act
     of 1939) outstanding under any other indenture (i) under which the Trustee
     is also trustee, (ii) which contains provisions substantially similar to
     the provisions of subsection (a) of this Section and (iii) under which a
     default exists at the time of the apportionment of the funds and property
     held in said special account;

               (3)  the term "cash transaction" shall mean any transaction in
     which full payment for goods or securities sold is made within seven days
     after delivery of the goods or securities in currency or in checks or other
     orders drawn upon banks or bankers and payable upon demand;

               (4)  the term "self-liquidating paper" shall mean any draft, bill
     of exchange, acceptance or obligation which is made, drawn, negotiated or
     incurred by the Issuer for the purpose of financing the purchase,
     processing, manufacture, shipment, storage or sale of goods, wares or
     merchandise and which is secured by documents evidencing title to,
     possession of, or a lien upon, the goods, wares or merchandise or the
     receivables or proceeds arising from the sale of the goods, wares or
     merchandise previously constituting the security, provided the security is
     received by the Trustee simultaneously with the creation of the creditor
     relationship with the Issuer arising from the making, drawing, negotiating
     or incurring of the draft, bill of exchange, acceptance or obligation; and 

               (5)  the term "Issuer" shall mean any obligor upon the
     Securities.

          SECTION 6.14  APPOINTMENT OF AUTHENTICATING AGENT.  As long as any 
Securities of a series remain Outstanding, the Trustee may, by an instrument 
in writing, appoint with the approval of the Issuer an authenticating agent 
(the "Authenticating Agent") which shall be authorized to act on behalf of, 
but subject to the direction of, the Trustee to authenticate Securities of 
such series, including Securities issued upon exchange, registration of 
transfer, partial redemption or pursuant to Section 2.9.   Securities of such 
series 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. Whenever reference is made in this Indenture to the authentication 
and delivery of Securities of any series by the Trustee or to 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 for such series and a certificate of authentication executed on behalf 
of the Trustee by such Authen-


                                   -62-



ticating Agent.  Such Authenticating Agent shall at all times be a 
corporation organized and doing business under the laws of the United States 
of America or of any State thereof or of the District of Columbia authorized 
under such laws to exercise corporate trust powers, having a combined capital 
and surplus of at least $5,000,000 (determined as provided in Section 6.9 
with respect to the Trustee) and subject to supervision or examination by 
Federal or State authority.  

          Any corporation into which any 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 any 
Authenticating Agent shall be a party, or any corporation succeeding to the 
corporate agency or corporate trust business of any Authenticating Agent, 
shall be the successor to such Authenticating Agent with respect to all 
series of Securities for which it served as Authenticating Agent without the 
execution or filing of any paper or any further act on the part of the 
Trustee or such Authenticating Agent.  

          Any Authenticating Agent may at any time, and if it shall cease to 
be eligible hereunder shall, resign by giving written notice of resignation 
to the Trustee and to the Issuer.  The Trustee may at any time terminate the 
agency of any Authenticating Agent by giving written notice thereof to such 
Authenticating Agent and the Issuer.  Upon receiving such a notice of 
resignation or upon such a termination, or in case at any time any 
Authenticating Agent shall cease to be eligible in accordance with the 
provisions of this Section, the Trustee shall upon receipt of an Issuer order 
appoint a successor Authenticating Agent and shall provide notice of such 
appointment to all Holders of Securities affected thereby in the manner and 
to the extent provided in Section 6.11 with respect to the appointment of a 
successor trustee.  Any successor Authenticating Agent upon acceptance of its 
appointment hereunder shall become vested with all rights, powers and duties 
of its predecessor hereunder, with like effect as if originally named as an 
Authenticating Agent.  

          Sections 6.2, 6.3, 6.4, 6.6 (except for the last sentence thereof) 
and 7.3 shall be applicable to any Authenticating Agent.  

                                    ARTICLE SEVEN

                            CONCERNING THE SECURITYHOLDERS
                                           
          SECTION 7.1  EVIDENCE OF ACTION TAKEN BY SECURITYHOLDERS.  Any
request, demand, authorization, direction, notice, consent, waiver or other
action provided by this Indenture to be given or taken by a specified percentage
in 


                                   -63-




aggregate principal amount of the Holders of one or more series may be 
evidenced by one or more instruments of substantially similar tenor signed by 
such specified percentage of Holders in person or by agent or proxy duly 
appointed in writing; and, except as herein otherwise expressly provided, 
such action shall become effective when such instrument or instruments are 
delivered to the Trustee.  

          SECTION 7.2  PROOF OF EXECUTION OF INSTRUMENTS AND OF HOLDING OF 
SECURITIES.  Subject to Sections 6.1 and 6.2, proof of the execution of any 
instrument by a Holder or his agent or proxy shall be sufficient if made in 
accordance with such reasonable rules and regulations as may be prescribed by 
the Trustee or in such manner as shall be satisfactory to the Trustee.  
Subject to Sections 6.1 and 6.2, proof of the holding by any Person of any of 
the Securities of any series shall be sufficient if made in the following 
manner: 

          (a)  The ownership of an Unregistered Security of any series, or of
     any Coupon attached thereto at its issuance, and the identifying number of
     such Security and the date of such ownership, may be proved by the
     production of such Security or Coupon or by a certificate executed by any
     trust company, bank, banker or recognized securities dealer, wherever
     situated, if such certificate shall be deemed by the Trustee to be
     satisfactory.  Each such certificate shall be dated and shall state that on
     the date thereof a Security of such series bearing a specified identifying
     number was deposited with or exhibited to such trust company, bank, banker
     or recognized securities dealer by the person named in such certificate. 
     Any such certificate may be issued in respect of one or more Unregistered
     Securities of one or more series specified therein.  The ownership by the
     Person named in any such certificate of any Unregistered Security specified
     therein shall be presumed to continue unless at the time of any
     determination of such ownership and holding (1) another certificate bearing
     a later date issued in respect of such Security shall be produced, (2) such
     security shall be produced by some other Person or (3) such Security shall
     have ceased to be Outstanding.  

     Subject to Sections 6.1 and 6.2, the fact and date of the execution of any
     such instrument and the ownership, amount and numbers of any Unregistered
     Securities may also be proven in accordance with such reasonable rules and
     regulations as may be prescribed by the Trustee for any series or in any
     other manner which the Trustee may deem sufficient.  

          (b)  In the case of Registered Securities, the ownership of such
     Securities shall be proved by the Security Register or by a certificate of
     the Security Registrar.  

                                   -64-




          SECTION 7.3  HOLDERS TO BE TREATED AS OWNERS.  The Issuer, the 
Trustee and any agent of the Issuer or the Trustee may deem and treat the 
Person in whose name any Security of any series shall be registered upon the 
Security Register for such series as the absolute owner of such Security 
(whether or not such Security shall be overdue and notwithstanding any 
notation of ownership or other writing thereon) for the purpose of receiving 
payment of or on account of the principal of and, subject to the provisions 
of this Indenture, interest on such security and for all other purposes; and 
none of the Issuer, the Trustee and any agent of the Issuer or the Trustee 
shall be affected by any notice to the contrary.  The Issuer, the Trustee and 
any agent of the Issuer or the Trustee may treat the Holder of any 
Unregistered Security and the Holder of any Coupon as the absolute owner of 
such Unregistered Security or Coupon (whether or not such Unregistered 
Security or Coupon shall be overdue) for the purpose of receiving payment 
thereof or on account thereof and for all other purposes; and none of the 
Issuer, the Trustee and any agent of the Issuer or the Trustee shall be 
affected by any notice to the contrary.  All such payments so made to any 
such Person, or upon his order, shall be valid, and, to the extent of the sum 
or sums so paid, effectual to satisfy and discharge the liability for moneys 
payable upon any such Security or Coupon.  

          SECTION 7.4  SECURITIES OWNED BY ISSUER DEEMED NOT OUTSTANDING.  In 
determining whether the Holders of the requisite aggregate principal amount 
of Outstanding Securities of one or more series have concurred in any 
direction, consent or waiver under this Indenture, Securities which are owned 
by the Issuer or any other obligor on the Securities with respect to which 
such determination is being made or by any Person directly or indirectly 
controlling or controlled by or under direct or indirect common control with 
the Issuer or any other obligor on the Securities with respect to which such 
determination is being made shall be disregarded and deemed not to be 
Outstanding for the purposes of any such determination, except that for the 
purpose of determining whether the Trustee shall be protected in relying on 
any such direction, consent or waiver, only Securities which the Trustee 
knows are so owned shall be so disregarded. Securities so owned which have 
been pledged in good faith may be regarded as outstanding if the pledgee 
establishes to the satisfaction of the Trustee the pledgee's right so to act 
with respect to such Securities and that the pledgee is not the Issuer or any 
other obligor upon such Securities or any Person directly or indirectly 
controlling or controlled by or under direct or indirect common control with 
the Issuer or any other obligor on such Securities.  In case of a dispute as 
to such right, the advice of counsel shall be full protection in respect of 
any decision made by the Trustee in accordance with such advice. Upon request 
of the Trustee, the Issuer shall furnish to the Trustee promptly an Officers' 
Certificate listing and identifying 


                                   -65-



all Securities, if any, known by the Issuer to be owned or held by or for the 
account of any of the above described Persons; and, subject to Sections 6.1 
and 6.2, the Trustee shall be entitled to accept such Officers' Certificate 
as conclusive evidence of the facts therein set forth and of the fact that 
all securities not listed therein are Outstanding for the purposes of any 
such determination.  

          SECTION 7.5  RIGHT OF REVOCATION OF ACTION TAKEN.  At any time 
prior to (but not after) the evidencing to the Trustee, as provided in 
Section 7.1, of the taking of any action by the Holders of the requisite 
percentage in aggregate principal amount of the Securities of one or more 
series, as the case may be, specified in this Indenture in connection with 
such action, any Holder of a Security the serial number of which is shown by 
the evidence to be included among the serial numbers of the Securities the 
Holders of which have consented to such action may, by filing written notice 
at the Corporate Trust Office and upon proof of ownership as provided in 
Section 7.2, revoke such action so far as concerns such Security.  Except as 
aforesaid, any such action taken by the Holder of any Security of any series 
shall be conclusive and binding upon such Holder and upon all future Holders 
and owners of such Security and of any Securities of such series issued in 
exchange or substitution therefor or on registration of transfer thereof, 
irrespective of whether or not any notation in regard thereto is made upon 
any such Security.  Any action taken by the Holders of the requisite 
percentage in aggregate principal amount of the Securities of one or more 
series, as the case may be, specified in this Indenture in connection with 
such action shall be conclusively binding upon the Issuer, the Trustee and 
the Holders of all the Securities of such series.  

          With respect to Registered Securities, the Issuer may, but shall 
not be obligated to, fix a record date for the purpose of determining the 
Securityholders entitled to give their consent or take any other action 
described above.  If a record date is fixed, then notwithstanding the 
immediately preceding paragraph those Persons who were Holders of such 
Registered Securities at such record date (or their duly designated proxies), 
and only those Persons, shall be entitled to give such consent or to revoke 
any consent previously given or to take any such action with respect to such 
Registered Securities, whether or not such Persons continue to be Holders 
after such record date.  No such consent shall be valid or effective for more 
than 120 days after such record date.

                               SUPPLEMENTAL INDENTURES
                                           
          SECTION 8.1  SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF
SECURITYHOLDERS.  The Issuer, when authorized by a resolution of the Board of
Directors (which resolution may provide general terms or parameters for such
action and may provide that the specific terms of such action may be determined
in accordance with or pursuant to an Issuer Order), and the Trustee may, from
time to time and at any time, enter into an indenture or indentures supplemental
hereto (which shall conform to the provisions of the Trust Indenture Act of 1939
as in force at the date of the execution thereof) for one or more of the
following purposes:

          (a)  subject to Section 3.6, to convey, transfer, assign, mortgage or
     pledge to the Trustee as security for the Securities of one or more series
     any property or assets; 

          (b)  to add guarantees with respect to the Securities of one or more
     series; 

          (c)  to evidence the succession of another corporation to the Issuer,
     or successive successions, and the assumption by the successor corporation
     of the covenants, agreements and obligations of the Issuer pursuant to
     Article Nine;

          (d)  to add to the covenants of the Issuer such further covenants,
     restrictions, conditions or provisions as the Issuer and the Trustee shall
     consider to be for the protection of the Holders of Securities of any
     series or Coupons appertaining thereto, and to make the occurrence, or the
     occurrence and continuance, of a default in complying with any such
     additional covenant, restriction, condition or provision an Event of
     Default permitting the enforcement of all or any of the several remedies
     provided in this Indenture as herein set forth; in respect of any such
     additional covenant, restriction, condition or provision, such supplemental
     indenture may provide for a particular period of grace after default (which
     period may be shorter or longer than that allowed in the case of other
     defaults) or may provide for an immediate enforcement upon such an Event of
     Default or may limit the remedies available to the Trustee upon such an
     Event of Default or may limit the right of the Holders of a majority in
     aggregate principal amount of the Securities of such series to waive such
     an Event of Default;

          (e)  to cure any ambiguity or to correct or supplement any provision
     contained herein or in any supplemental indenture which may be defective or
     inconsistent with any other provision contained herein or in any
     supplemental 


                                   -67-



     indenture, or to make such other provisions as the Issuer may
     deem necessary or desirable, PROVIDED that no such action shall adversely
     affect the interests of the Holders of the Securities of any series or the
     Coupons appertaining thereto;

          (f)  to establish the form and terms of the securities of any series
     or of the Coupons appertaining to such Securities, as permitted by 
     Sections 2.1 and 2.3;

          (g)  to evidence and provide for the acceptance of appointment
     hereunder by a successor trustee with respect to the Securities of one or
     more series and to add to or change any of the provisions of this Indenture
     as shall be necessary to provide for or facilitate the administration of
     the trusts hereunder by more than one trustee, all as provided in Section
     6.11; 

          (h)  to provide for uncertificated Securities in addition to or in
     place of certificated Securities; PROVIDED, HOWEVER, that the
     uncertificated Securities are issued in registered form for purposes of
     Section 163(f) of the  Internal Revenue Code of 1986, as amended, or in a
     manner such that the uncertificated Securities are described in Section
     163(f)(2)(B) of the Internal Revenue Code of 1986, as amended; and 

          (i)  to comply with any requirements of the Commission in connection
     with qualifying this Indenture under the Trust Indenture Act of 1939.  

          The Trustee is hereby authorized to join with the Issuer in the 
execution of any such supplemental indenture, to make any further appropriate 
agreements and stipulations which may be therein contained and to accept the 
conveyance, transfer, assignment, mortgage or pledge of any property or 
assets thereunder, but the Trustee 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.  

          Any supplemental indenture authorized by the provisions of this 
Section may be executed without the consent of the Holders of any of the 
Securities at the time Outstanding, notwithstanding any of the provisions of 
Section 8.2.  

          SECTION 8.2  SUPPLEMENTAL INDENTURES WITH CONSENT OF 
SECURITYHOLDERS. With the consent (evidenced as provided in Article Seven) of 
the Holders of not less than a majority in aggregate principal amount of the 
Securities of all series at the time Outstanding affected by such 
supplemental indenture (voting as one class), the Issuer, when authorized by 
a resolution of the Board of Directors (which resolution may provide general 
terms or 


                                   -68-




parameters for such action and may provide that the specific terms of such 
action may be determined in accordance with or pursuant to an Issuer order), 
and the Trustee may, from time to time and at any time, enter into an 
indenture or indentures supplemental hereto (which shall conform to the 
provisions of the Trust Indenture Act of 1939 as in force at the date of 
execution thereof) for the purpose of adding any provisions to or changing in 
any manner or eliminating any of the provisions of this Indenture or of any 
supplemental indenture or of modifying in any manner the rights of the 
Holders of the Securities of each such series or of the Coupons appertaining 
to such Securities; provided that no such supplemental indenture shall (a) 
extend the time of payment of the principal, or any installment of the 
principal, of any Security or reduce the principal amount thereof, or reduce 
the rate, alter the method of computation of the rate, or extend the time of 
payment of interest thereon, or reduce any amount payable on the redemption 
thereof, or make the principal thereof or the interest thereon payable in any 
coin or currency other than that provided in such Security and the Coupons, 
if any, appertaining thereto or in accordance with the terms thereof, or 
reduce the amount of the principal of an original Issue Discount Security 
that would be due and payable upon an acceleration of the maturity thereof 
pursuant to Section 5.1 or the amount thereof provable in bankruptcy, 
pursuant to Section 5.2, or alter the provisions of Section 11.11 or 11.12, 
or impair or affect the right to institute suit for the payment thereof when 
due or, if such Security shall so provide, any right of repayment at the 
option of the Holder, in each case without the consent of the Holder of each 
Security so affected, or (b) reduce the percentage in principal amount of the 
Outstanding Securities of the affected series, the consent of whose Holders 
is required for any such supplemental indenture or for any waiver provided 
for in this Indenture, without the consent of the Holders of each Security so 
affected.  

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

          Upon the request of the Issuer, accompanied by a Board Resolution 
complying with the first paragraph of this Section and evidence of the 
consent of the Holders of the Securities as aforesaid and such other 
documents, if any, as may be required by Section 7.1, the Trustee shall join 
with the Issuer in the execution of such supplemental indenture unless such 
supplemental indenture affects the Trustee's own rights, duties or immunities 


                                   -69-



under this Indenture or otherwise, in which case the Trustee may in its 
discretion, but shall not be obligated to, enter into such supplemental 
indenture.  

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

          Promptly after the execution by the Issuer and the Trustee of any 
supplemental indenture pursuant to the provisions of this Section, the 
Trustee shall give notice thereof (i) to the Holders of then Outstanding 
Registered Securities of each series affected thereby, by mailing a notice 
thereof by first-class mail to such Holders at their addresses as they shall 
appear on the Security Register, (ii) if any unregistered Securities of a 
series affected thereby are then Outstanding, to the Holders thereof who have 
filed their names and addresses with the Trustee pursuant to Section 
4.4(c)(ii), by mailing a notice thereof by first-class mail to such Holders 
at such addresses as were so furnished to the Trustee and (iii) if any 
Unregistered Securities of a series affected thereby are then Outstanding, to 
all Holders thereof, by publication of a notice thereof at least once in each 
Authorized Newspaper with respect to such series, and in each case such 
notice shall set forth in general terms the substance of such supplemental 
indenture.  Any failure of the Issuer to give such notice, or any defect 
therein, shall not, however, in any way impair or affect the validity of any 
such supplemental indenture.  

          SECTION 8.3  EFFECT OF SUPPLEMENTAL INDENTURE.  Upon the execution 
of any supplemental indenture pursuant to the provisions hereof, this 
Indenture shall be and be deemed to be modified and amended in accordance 
therewith and the respective rights, limitations of rights, obligations, 
duties and immunities under this Indenture of the Trustee, the Issuer and the 
Holders of Securities of each series affected thereby shall thereafter be 
determined, exercised and enforced hereunder subject in all respects to such 
modifications and amendments, and all the terms and conditions of any such 
supplemental indenture shall be and be deemed to be part of the terms and 
conditions of this Indenture for any and all purposes.  

          SECTION 8.4  DOCUMENTS TO BE GIVEN TO TRUSTEE.  The Trustee, 
subject to the provisions of Sections 6.1 and 6.2, may receive an Officers' 
Certificate and an Opinion of Counsel as conclusive evidence that any 
supplemental indenture executed pursuant to this Article complies with the 
applicable provisions of this Indenture.  

          SECTION 8.5  NOTATION ON SECURITIES IN RESPECT OF SUPPLEMENTAL 
INDENTURES.  Securities of any series authenticated 


                                   -70-




and delivered after the execution of any supplemental indenture pursuant to 
the provisions of this Article may bear a notation in form approved by the 
Trustee as to any matter provided for by such supplemental indenture.  If a 
supplemental indenture changes the terms of a Security, the Trustee may 
require the Holder of such Security to deliver it to the Trustee, and the 
Trustee may place an appropriate notation on the Security regarding the 
changed terms and return it to such Holder.  Alternatively, if the Issuer or 
the Trustee shall so determine, new Securities of any series so modified as 
to conform, in the opinion of the Trustee and the Issuer, to any modification 
of this Indenture contained in any such supplemental indenture may be 
prepared by the Issuer, authenticated by the Trustee and delivered in 
exchange for the Securities of such series then Outstanding.  Any failure to 
make any such notation or to issue a new Security shall not, however, in any 
way impair or affect the validity of any such supplemental indenture or any 
such Security the terms of which are changed.  

                                     ARTICLE NINE

                      CONSOLIDATION, MERGER, SALE OR CONVEYANCE

          SECTION 9.1  COVENANT OF ISSUER NOT TO MERGE, CONSOLIDATE, SELL OR 
CONVEY PROPERTY EXCEPT UNDER CERTAIN CONDITIONS.  Nothing contained in this 
Indenture or in any of the Securities shall prevent any consolidation of the 
Issuer with, or merger of the Issuer into, any other Person or Persons 
(whether or not affiliated with the Issuer), or successive consolidations or 
mergers to which the Issuer or its successor or successors shall be a party 
or parties, or shall prevent any sale, lease or conveyance of the property of 
the Issuer as an entirety or substantially as an entirety; PROVIDED, that, 
and the Issuer hereby covenants and agrees, upon any such consolidation, 
merger, sale, lease or conveyance, the due and punctual payment of the 
principal of and interest on all the Securities, according to their tenor, 
and the due and punctual performance and observance of all of the covenants, 
conditions and other obligations of this Indenture and the Securities to be 
performed or observed by the Issuer, shall be expressly assumed, by 
supplemental indenture satisfactory in form to the Trustee, executed and 
delivered to the Trustee by the Person formed by such consolidation, or into 
which the Issuer shall have been merged, or which shall have acquired such 
property; PROVIDED, FURTHER, that the Person formed by such consolidation or 
into which the Issuer is merged or the Person which acquired by conveyance or 
sale, or which leases, the properties and assets of the Issuer as an entirety 
or substantially as an entirety shall be either (i) a Person organized and 
existing under the laws Of the United States, any state thereof or the 
District of Columbia or (ii) a Person organized and existing under the laws 
of Canada, Japan, 


                                   -71-




Australia, New Zealand, any Specified European Nation or of any political 
subdivision of any thereof and such Person undertakes to pay to the Holders 
of Securities any additional amounts as may be necessary in order that every 
net payment of principal of and interest, if any, on the Securities, after 
withholding for or on account of any present or future tax, assessment or 
governmental charge imposed upon such Holder (except for a tax, assessment or 
charge imposed solely as a result of a connection between the recipient and 
the jurisdiction imposing such tax assessment or charge) by reason of or as a 
result of such payment being made by an entity which is not a Person existing 
under the laws of the United States or any state thereof or the District of 
Columbia, will not be less than the amount provided for in the Securities to 
be then due and payable; and PROVIDED, FURTHER, that immediately after giving 
effect to such transaction (and treating any Secured Debt or Sale and 
Leaseback Transaction which becomes an obligation of the resulting, surviving 
or transferee Person as a result of such transaction as having been incurred 
or entered into by such Person at the time of such transaction), no Event of 
Default, and no event which, after notice or lapse of time or both, would 
become an Event of Default, shall have happened and be continuing.  

          SECTION 9.2  SECURITIES TO BE SECURED IN CERTAIN EVENTS.  If, upon 
any such consolidation or merger of the Issuer or upon any such sale, lease 
or conveyance of the property of the Issuer as an entirety or substantially 
as an entirety to any other Person, any property owned by the Issuer 
immediately prior thereto would thereupon become subject to any Lien (unless 
the Secured Debt in respect of such Lien could have been incurred by the 
Issuer without its being required by the provisions of Section 3.6 to secure 
the Securities equally and ratably with (or prior to) such Secured Debt), the 
Issuer, prior to any such consolidation, merger, sale, lease or conveyance, 
will by indenture supplemental hereto secure the Securities (together with, 
if the Issuer shall so determine, any other Debt incurred, assumed or 
guaranteed by the Issuer ranking equally with, or prior to, the Securities, 
whether then existing or thereafter created) by a direct Lien on such 
property, prior to all Liens other than any theretofore existing thereon.  

          SECTION 9.3  SUCCESSOR PERSON SUBSTITUTED FOR ISSUER.  In case of 
any consolidation, merger, sale, lease or conveyance referred to in Section 
9.1, and following such an assumption by the successor Person, such successor 
Person shall succeed to and be substituted for the Issuer, with the same 
effect as if it had been named herein.  

          Such successor Person may cause to be signed, and may issue either 
in its own name or in the name of the Issuer prior to such succession, any or 
all of the Securities issuable hereunder which theretofore shall not have 
been signed by the 


                                   -72-



Issuer and delivered to the Trustee; and, upon the order of such successor 
Person, instead of the Issuer, and subject to all the terms, conditions and 
limitations in this Indenture prescribed, the Trustee shall authenticate and 
shall deliver any Securities which previously shall have been signed and 
delivered by the officers of the Issuer to the Trustee for authentication, 
and any Securities which such successor Person thereafter shall cause to be 
signed and delivered to the Trustee for that purpose.  All of the Securities 
so issued shall in all respects have the same legal rank and benefit under 
this Indenture as the Securities theretofore or thereafter issued in 
accordance with the terms of this Indenture as though all of such Securities 
had been issued at the date of the execution hereof.  

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

          In the event of any such sale or conveyance (other than a 
conveyance by way of lease), the Issuer or any successor Person which shall 
theretofore have become such in the manner described in this Article shall be 
discharged from all obligations and covenants under this Indenture and the 
Securities and may be liquidated and dissolved.  

          SECTION 9.4  OFFICERS' CERTIFICATE AND OPINION OF  COUNSEL 
DELIVERED TO TRUSTEE.  The Trustee, subject to the provisions of Sections 6.1 
and 6.2, may receive an Officers' Certificate and an Opinion of Counsel each 
stating that any such consolidation, merger, sale, lease or conveyance, that 
any such assumption, that any such supplemental indenture and that any such 
liquidation or dissolution, complies with the applicable provisions of this 
Indenture.  

                                     ARTICLE TEN
                                           
                       SATISFACTION AND DISCHARGE OF INDENTURE;
                                   UNCLAIMED MONEYS            
                                           
          SECTION 10.1  SATISFACTION AND DISCHARGE OF INDENTURE.  (A) If at 
any time (a) the Issuer shall have paid or caused to be paid the principal of 
and interest on all the securities of each series theretofore authenticated, 
including all Coupons appertaining thereto (other than Securities and Coupons 
appertaining thereto which have been destroyed, lost or stolen and which have 
been replaced or paid as provided in Section 2.9), in accordance with the 
terms of this Indenture and such Securities or (b) as to securities and

cancellation all Securities of each series theretofore authenticated and all 


                                   -73-




coupons appertaining thereto (other than any Securities and Coupons 
appertaining thereto which shall have been destroyed, lost or stolen and 
which shall have been replaced or paid as provided in Section 2.9) or (c) as 
to Securities and Coupons not so paid or delivered for cancellation, in the 
case of any series of Securities as to which the exact amount (including the 
currency of payment) of principal of and interest due can be determined at 
the time of making the deposit referred to in clause (ii) below, (i) all the 
Securities of such series and all Coupons appertaining thereto shall have 
become due and payable, and (ii) the Issuer shall have irrevocably deposited 
or caused to be deposited with the Trustee as trust funds the entire amount 
in cash (other than moneys repaid by the Trustee or any paying agent to the 
Issuer in accordance with Section 10.4) to pay the principal and interest on 
all Securities of such series and Coupons appertaining thereto at maturity; 
and if, in the case of (a), (b) or (c), the Issuer shall also pay or cause to 
be paid all other sums payable hereunder by the Issuer, then this Indenture 
shall, subject to Section 10.6, cease to be of further effect (except as to 
(i) rights of registration of transfer and exchange of Securities and of 
Coupons appertaining thereto and the Issuer's right of optional redemption, 
if any, (ii) substitution of mutilated, defaced, destroyed, lost or stolen 
Securities or Coupons, (iii) the rights of Holders of Securities and Coupons 
appertaining thereto to receive payments of principal thereof and interest

4.1 and 9.3 and the first and second provisos of Section 9.1 and (vii) this 
Article 10 pertinent to such continuing obligations); and the Trustee, on 
demand of the Issuer accompanied by an Officers' Certificate and an Opinion 
of Counsel, each stating that all conditions precedent herein provided for 
relating to the satisfaction and discharge of this Indenture have been 
complied with, and at the cost and expense of the Issuer, shall execute 
proper instruments acknowledging such satisfaction and discharge of this 
Indenture; provided that the rights of Holders of the Securities and Coupons 
to receive amounts in respect of principal of and interest on the Securities 
and Coupons held by them shall not be delayed longer than required by then 
applicable mandatory rules or policies of any national securities exchange 
upon which the Securities are listed.  The Issuer agrees to reimburse the 
Trustee for any costs or expenses thereafter reasonably and properly incurred 
and to compensate the Trustee for any services thereafter reasonably and 
properly rendered by the Trustee in connection with this Indenture or the 
securities.


                                   -74-



          (B)  The following provisions shall apply to the Securities of each 
series unless specifically otherwise provided in the Board Resolution, 
Officers' Certificate or supplemental indenture relating thereto provided 
pursuant to Section 2.3.  In addition to discharge of this Indenture pursuant 
to the next preceding paragraph (A), in the case of any series of Securities 
as to which the exact amount (including the currency of payment) of principal 
of and interest due can be determined at the time of making the deposit 
referred to in subparagraph (a) below, the Issuer shall be deemed to have 
paid and discharged the entire indebtedness on all the Securities of such 
series and the Coupons appertaining thereto on the 91st day after the date of 
such deposit, and the provisions of this Indenture with respect to the 
Securities of such series and Coupons appertaining thereto shall, subject to

Coupons appertaining thereto and the Issuer's right of optional redemption, 
if any, (ii) substitution of mutilated, defaced, destroyed, lost or stolen 
Securities or Coupons, (iii) the rights of Holders of Securities of such 
series and Coupons appertaining thereto to receive payments of principal 
thereof and interest thereon, upon the original stated due dates therefor 
(but not upon acceleration), and remaining rights of such Holders to receive 
mandatory sinking fund or analogous payments, if any, solely from the trust 
fund referred to in subparagraph (a) below, (iv) the rights, obligations, 
duties and immunities of the Trustee hereunder, (v) the rights of Holders of 
Securities of such series and Coupons appertaining thereto as beneficiaries 
hereof with respect to the property so deposited with the Trustee and payable 
to all or any of them, (vi) the obligations of the Issuer under Sections 3.2,

Trustee, at the cost and expense of the Issuer, shall, at the Issuer's 
request, execute proper instruments acknowledging the same, if:

          (a)  the Issuer shall have irrevocably deposited or caused to be
     irrevocably deposited with the Trustee as a trust fund specifically pledged
     as security for, and dedicated solely to, the benefit of the Holders of the
     Securities of such series and Coupons appertaining thereto (i) cash in an
     amount, or (ii) Government Obligations, maturing as to principal and
     interest at such times and in such amounts as will insure the availability
     of cash, or (iii) a combination thereof, sufficient in the opinion of a
     nationally recognized firm of independent public accountants expressed in a
     written certification thereof delivered to the Trustee, to pay (A) the
     principal and interest on all Securities of such series and Coupons
     appertaining thereto on each date that such principal or interest is due
     and payable and (B) any mandatory sinking fund or analogous 


                                   -75-



     payments on the dates on which such payments are due and payable in 
     accordance with the terms of this Indenture and the Securities of such 
     series;

          (b)  no Event of Default or event which, with notice or lapse of time
     or both, would become an Event of Default with respect to the Securities of
     such series shall have occurred and be continuing on the date of such
     deposit or, insofar as clauses (e) and (f) of Section 5.1 are concerned, at
     any time during the period ending on the 91st day after the date of such
     deposit (it being understood that this condition shall not be deemed
     satisfied until the expiration of such period);

          (c)  such deposit, defeasance and discharge shall not result in a
     breach or violation of, or constitute a default under, this Indenture or
     any other agreement or instrument to which the Issuer is a party or by
     which it is bound;

          (d)  such deposit, defeasance and discharge shall not cause any
     Securities of such series then listed on any national securities exchange
     registered under the Exchange Act to be delisted;

          (e)  the Issuer shall have delivered to the Trustee an Opinion of
     Counsel (which counsel shall be counsel selected by the Issuer with
     national recognition in matters of federal income tax law) to the effect
     that either (A) there has been a change in the applicable Federal income
     tax law or (B) the Issuer has received from, or there has been published
     by, the Internal Revenue Service a ruling to the effect that, and in any
     such case referred to in clause (A) or (B) such Opinion of Counsel shall
     confirm that based thereon, the Holders of the Securities of such series
     then Outstanding and Coupons appertaining thereto will not recognize
     income, gain or loss for Federal income tax purposes as a result of such
     deposit, defeasance and discharge and will be subject to Federal income tax
     on the same amounts, in the same manner and at the same times as would have
     been the case if such deposit, defeasance and discharge had not occurred;
     and

          (f)  the Issuer shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent herein provided for relating to the defeasance contemplated by
     this paragraph have been complied with.

          (C)  The Issuer shall be released from its obligations under 
Sections 3.5, 3.6 and 3.7 and Article Nine (other than the first and second 
provisos of Section 9.1 with respect to the Securities of a particular series 
and any Coupons appertaining 


                                   -76-



thereto Outstanding on and after the date the conditions set forth below are 
satisfied (hereinafter, "covenant defeasance")). Covenant defeasance means 
that, with respect to the Outstanding Securities of such series, the Issuer 
may omit to comply with and shall have no liability in respect of any term, 
condition or limitation set forth in Sections 3.5, 3.6 and 3.7 and Article 
Nine, whether directly or indirectly by reason of any reference elsewhere 
herein to any such Section or Article, by reason of any reference in such 
Section or Article to any other provision herein or by reason of any 
reference to any such Section or Article in any other document, and such 
omission to comply shall not constitute an Event of Default under Section 5.1 
with respect to the Outstanding Securities of such series, but the remainder 
of this Indenture and other Outstanding Securities and Coupons shall be 
unaffected thereby.  The following shall be the conditions to application of 
this paragraph (C):

          (a)  the Issuer shall have irrevocably deposited or caused to be
     irrevocably deposited with the Trustee as a trust fund specifically pledged
     as security for, and dedicated solely to, the benefit of the Holders of the
     Securities of such series and Coupons appertaining thereto, (i) cash in an
     amount, or (ii) Government Obligations, maturing as to principal and
     interest at such times and in such amounts as will insure the availability
     of cash, or (iii) a combination thereof, sufficient in the opinion of a
     nationally recognized firm of independent public accountants expressed in a
     written certification thereof delivered to the Trustee, to pay (A) the
     principal and interest on all Securities of such series and Coupons
     appertaining thereto on each date that such principal or interest is due
     and payable and (B) any mandatory sinking fund or analogous payments on the
     dates on which such payments are due and payable in accordance with the
     terms of this Indenture and the Securities of such series;

          (b)  no Event of Default or event which, with notice or lapse of time
     or both, would become an Event of Default with respect to the Securities of
     such series shall have occurred and be continuing on the date of such
     deposit or, insofar as clauses (e) and (f) of Section 5.1 are concerned, at
     any time during the period ending on the 91st day after the date of such
     deposit (it being understood that this condition shall not be deemed
     satisfied until the expiration of such period);

          (c)  such deposit and covenant defeasance shall not result in a breach
     or violation of, or constitute a default under, this Indenture or any other
     agreement or instrument to which the Issuer is a party or by which it is
     bound;


                                   -77-



          (d)  such deposit and 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;

          (e)  the Issuer shall have delivered to the Trustee an Opinion of
     Counsel (which counsel shall be counsel selected by the Issuer with
     national recognition in matters of federal income tax law) to the effect
     that the Holders of the Securities of such series then Outstanding and
     Coupons appertaining thereto will not recognize income, gain or loss for
     Federal income tax purposes as a result of such deposit and covenant
     defeasance and will be subject to Federal income tax on the same amounts,
     in the same manner and at the same times as would have been the case if
     such deposit and covenant defeasance had not occurred; and

          (f)  the Issuer shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent herein provided for relating to such covenant defeasance have
     been complied with.

          SECTION 10.2  APPLICATION BY TRUSTEE OF FUNDS DEPOSITED FOR PAYMENT 
OF SECURITIES.  Subject to Section 10.4, all moneys deposited with the 
Trustee pursuant to Section 10.1 in respect of the Outstanding Securities of 
a particular series and the Coupons appertaining thereto shall be held in 
trust and applied by it to the payment, either directly or through any paying 
agent (including the Issuer acting as its own paying agent), to the Holders 
of such Securities and Coupons of all sums due and to become due thereon for 
principal and interest; but such money need not be segregated from other 
funds except to the extent required by law.

          SECTION 10.3  REPAYMENT OF MONEYS HELD BY PAYING AGENT.  In 
connection with the satisfaction and discharge of this Indenture with respect 
to the Securities of any series, all moneys then held by any paying agent 
under the provisions of this Indenture with respect to such series of 
Securities shall, upon demand of the Issuer, be paid to the Trustee and 
thereupon such paying agent shall be released from all further liability with 
respect to such moneys.

          SECTION 10.4  RETURN OF MONEYS HELD BY TRUSTEE AND PAYING AGENT 
UNCLAIMED FOR TWO YEARS.  Any moneys deposited with or paid to the Trustee or 
any paying agent for the payment of the principal of or interest on any 
Security of any series or Coupons appertaining thereto and not applied but 
remaining unclaimed for two years after the date upon which such principal or 
interest shall have become due and payable, shall, upon the written request 
of the Issuer and unless otherwise required by mandatory provisions of 
applicable escheat or abandoned or unclaimed property law, be repaid to the 
Issuer by the Trustee or such paying agent, and the Holder of the Securities 
of such series and of any Coupons appertaining thereto shall, unless 
otherwise required by mandatory 


                                   -78-



provisions of applicable escheat or abandoned or unclaimed property laws, 
thereafter look only to the Issuer for any payment which such Holder may be 
entitled to collect, and all liability of the Trustee or any paying agent 
with respect to such moneys shall thereupon cease; provided, however, that 
the Trustee or such paying agent, before being required to make any such 
repayment with respect to moneys deposited with it for any payment (a) in 
respect of Registered Securities of any series, shall at the expense of the 
Issuer, mail by first-class mail to Holders of such Securities at their 
addresses as they shall appear on the Security Register for the Securities of 
such series, (b) in respect of Unregistered Securities of any series, shall 
at the expense of the Issuer, mail by first-class mail to Holders of such 
Securities who have filed their names and addresses with the Trustee pursuant 
to Section 4.4(c)(ii) at such addresses as were so furnished to the Trustee 
and (c) in respect of Unregistered Securities of any series, shall at the 
expense of the Issuer cause to be published once, in each Authorized 
Newspaper with respect to such series, notice that such moneys remain and 
that, after a date specified therein, which shall not be less than 30 days 
from the date of such mailing or publication, any unclaimed balance of such 
moneys then remaining will be repaid to the Issuer.

          SECTION 10.5  INDEMNITY FOR GOVERNMENT OBLIGATIONS.  The Issuer 
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 10.1 or the principal or interest received in respect of such 
Government Obligations, other than any such tax, fee or other charge which by 
law is for the account of the Holders of the Securities and Coupons for whose 
benefit such Government Obligations are held.

          SECTION 10.6.  REINSTATEMENT.  If the Trustee or paying agent is 
unable to apply any money or Government Obligation in accordance with this 
Article 10 by reason of any legal proceeding or by reason of any order or 
judgment of any court or governmental authority enjoining, restraining or 
otherwise prohibiting such application, the Issuer's obligations under this 
Indenture and the Securities shall be revived and reinstated as though no 
deposit had occurred pursuant to this Article 10 until such time as the 
Trustee or paying agent is permitted to apply all such money or Government 
Obligations in accordance with this Article 10; PROVIDED, HOWEVER, that, if 
the Issuer has made any payment of interest on or principal of any Securities 
because of the reinstatement of its obligations, the Issuer shall be 
entitled, at its election, (a) to receive from the Trustee or paying agent, 
as applicable, that portion of such money or 


                                   -79-



Government Obligations equal to the amount of such payment or (b) to be 
subrogated to the rights of the Holders of such Securities to receive such 
payment from the money or Government Obligations held by the Trustee or 
paying agent.

                                    ARTICLE ELEVEN

                               MISCELLANEOUS PROVISIONS

          SECTION 11.1  INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS 
OF ISSUER EXEMPT FROM INDIVIDUAL LIABILITY.  No recourse under or upon any 
obligation, covenant or agreement contained in this Indenture, or in any 
Security or Coupon, or because of any indebtedness evidenced thereby, shall 
be had against any incorporator, as such, or against any past, present or 
future stockholder, officer or director, as such, of the Issuer or of any 
successor, either directly or through the Issuer or any successor, under any 
rule of law, statute or constitutional provision or by the enforcement of any 
assessment or by any legal or equitable proceeding or otherwise, all such 
liability being expressly waived and released by the acceptance of the 
Securities and the Coupons appertaining thereto by the Holders thereof and as 
part of the consideration for the issue of the Securities and the Coupons 
appertaining thereto.

          SECTION 11.2  PROVISIONS OF INDENTURE FOR THE SOLE BENEFIT OF 
PARTIES AND HOLDERS OF SECURITIES AND COUPONS.  Nothing in this Indenture, in 
the Securities or Coupons appertaining thereto, expressed or implied, shall 
give or be construed to give to any person, firm or corporation, other than 
the parties hereto and their successors and the Holders of the Securities or 
Coupons, if any, any legal or equitable right, remedy or claim under this 
Indenture or under any covenant or provision herein contained, all such 
covenants and provisions being for the sole benefit of the parties hereto and 
their successors and of the Holders of the Securities or Coupons, if any.

          SECTION 11.3  SUCCESSORS AND ASSIGNS OF ISSUER BOUND BY INDENTURE. 
All the covenants, stipulations, promises and agreements in this Indenture 
contained by or on behalf of the Issuer shall bind its successors and 
assigns, whether so expressed or not.

          SECTION 11.4  NOTICES AND DEMANDS ON ISSUER, TRUSTEE AND HOLDERS OF 
SECURITIES AND COUPONS.  Any notice or demand which by any provision of this 
Indenture is required or permitted to be given or served by the Trustee or by 
any Holder of Securities of any series or Coupons appertaining thereto to or 
upon the Issuer may be given or served in person or by being deposited 
postage prepaid in the United States mail, first-class 


                                   -80-



mail (except as otherwise specifically provided herein), addressed (until 
another address of the Issuer is filed by the Issuer with the Trustee) to 
United States Cellular Corporation, 8410 West Bryn Mawr Avenue, Suite 700, 
Chicago, Illinois 60631-3486, Attention: Chief Financial Officer.  Any 
notice, direction, request or demand by the Issuer or any Holder of 
Securities of any series or Coupons appertaining thereto to or upon the 
Trustee may be given or served in person or by being deposited postage 
prepaid in the United States mail, first-class mail (except as otherwise 
specifically provided herein), addressed (until another address of the 
Trustee is filed by the Trustee with the Issuer) to the Corporate Trust 
Office.  Any notice required or permitted to be given or served by the Issuer 
or by the Trustee to or upon (i) any Holders of Registered Securities of any 
series or any Holders of Unregistered Securities who have filed their names 
and addresses with the Trustee pursuant to Section 4.4(c)(ii), may be given 
or served by being deposited in the United States mail, first-class mail 
(except as otherwise specifically provided herein), addressed at their 
addresses as they shall appear on the Security Register or at the addresses 
so filed, respectively, and (ii) any Holders of other Unregistered 
Securities, by publication at least once in each Authorized Newspaper with 
respect to such series.

          In any case where notice to the Holders of Securities is given by 
mail, neither the failure to mail such notice, nor any defect in any notice 
so mailed, to any particular Holder shall affect the sufficiency of such 
notice with respect to other Holders.  Where this Indenture provides for 
notice in any manner, such notice may be waived in writing by the person 
entitled to receive such notice, either before or after the event, and such 
waiver shall be the equivalent of such notice.  Waivers of notice by Holders 
shall be filed with the Trustee, but such filing shall not be a condition 
precedent to the validity of any action taken in reliance upon such waiver.

          In case, by reason of the suspension of or irregularities in 
regular mail service, it shall be impracticable to mail notice to the Issuer 
when such notice is required to be given pursuant to any provision of this 
Indenture, then any manner of giving such notice as shall be reasonably 
satisfactory to the Trustee shall be deemed to be a sufficient giving of such 
notice.

          SECTION 11.5  OFFICERS' CERTIFICATES AND OPINIONS OF COUNSEL; 
STATEMENTS TO BE CONTAINED THEREIN.  Upon any application or demand by the 
Issuer to the Trustee to take any action under any of the provisions of this 
Indenture, the Issuer shall furnish to the Trustee an Officers' Certificate 
stating that all conditions precedent provided for in this Indenture relating 
to the proposed action have been complied with and an Opinion of Counsel 
stating that in the opinion of such counsel 


                                   -81-



all such conditions precedent have been complied with, except that in the 
case of any such application or demand as to which the furnishing of such 
documents is specifically required by any provision of this Indenture 
relating to such particular application or demand, no additional certificate 
or opinion need be furnished.

          Each certificate or opinion provided for in this Indenture and 
delivered to the Trustee with respect to compliance with a condition or 
covenant provided for in this Indenture shall include (a) a statement that 
the person making such certificate or opinion has read such covenant or 
condition, (b) a brief statement as to the nature and scope of the 
examination or investigation upon which the statements or opinions contained 
in such certificate or opinion are based, (c) a statement that, in the 
opinion of such person, he has made such examination or investigation as is 
necessary to enable him to express an informed opinion as to whether or not 
such covenant or condition has been complied with and (d) a statement as to 
whether or not, in the opinion of such person, such condition or covenant has 
been complied with.

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

          Any certificate, statement or opinion of an officer of the Issuer 
or of counsel may be based, insofar as it relates to accounting matters, upon 
a certificate or opinion of or representations by an accountant or firm of 
accountants in the employ of the Issuer, unless such officer or counsel, as 
the case may be, knows that the certificate or opinion or representations 
with respect to the accounting matters upon which his certificate, statement 
or opinion may be based as aforesaid are erroneous, or in the exercise of 
reasonable care should know that the same are erroneous.


                                   -82-



          Any certificate or opinion of any independent firm of public 
accountants filed with and directed to the Trustee shall contain a statement 
that such firm is independent.

          SECTION 11.6  PAYMENTS DUE ON SATURDAYS, SUNDAYS AND HOLIDAYS.  If 
the date of maturity of interest on or principal of the Securities of any 
series or any coupons appertaining thereto or the date fixed for redemption 
or repayment of any such Security or Coupon shall not be a Business Day, then 
payment of interest or principal need not be made on such date, but may be 
made on the next succeeding Business Day with the same force and effect as if 
made on the date of maturity or the date fixed for redemption or repayment, 
and no interest shall accrue for the period after such date.

          SECTION 11.7  CONFLICT OF ANY PROVISION OF INDENTURE WITH TRUST 
INDENTURE ACT OF 1939.  If and to the extent that any provision of this 
Indenture limits, qualifies or conflicts with another provision which is 
required to be included herein by the Trust Indenture Act of 1939 (as it may 
be amended from time to time), such required provision shall control.

          SECTION 11.8  ILLINOIS LAW TO GOVERN.  This Indenture and each 
Security and Coupon shall be deemed to be a contract under the laws of the 
State of Illinois, and for all purposes shall be construed in accordance with 
the laws of such State, except as may otherwise be required by mandatory 
provisions of law.

          SECTION 11.9  COUNTERPARTS.  This Indenture may be executed in any 
number of counterparts, each of which shall be an original; but such 
counterparts shall together constitute but one and the same instrument.

          SECTION 11.10  EFFECT OF HEADINGS.  The Article and Section 
headings herein and the Table of Contents are for convenience only and shall 
not affect the construction hereof.

          SECTION 11.11  SECURITIES IN A FOREIGN CURRENCY OR IN ECU.  Unless 
otherwise specified in or pursuant to a Board Resolution, a supplemental 
indenture or an Officers' Certificate delivered pursuant to Section 2.3 with 
respect to a particular series of securities, whenever for purposes of this 
Indenture any action may be taken by the Holders of a specified percentage in 
aggregate principal amount of Securities of one or more series at the time 
Outstanding and, at such time, there are Outstanding Securities of any series 
which are denominated in a Foreign Currency (including ECUs), then the 
principal amount of Securities of such series which shall be deemed to be 
Outstanding for the purpose of taking such action shall be the amount of 
Dollars that could be obtained for such amount at the Market Exchange Rate.  
For purposes of this Section, Market Exchange 


                                   -83-



Rate shall mean the noon Dollar buying rate in New York City for cable 
transfers of such Foreign Currency as published by the Federal Reserve Bank 
of New York; PROVIDED, HOWEVER, that in the case of ECUs, Market Exchange 
Rate shall mean the rate of exchange determined by the commission of the 
European Communities (or any successor thereto) as published in the Official 
Journal of the European Communities (such publication or any successor 
publication, the "Journal").  If such Market Exchange Rate is not available 
for any reason with respect to such Foreign Currency or ECUs, the Trustee 
shall use, in its sole discretion and without liability on its part, such 
quotation of the Federal Reserve Bank of New York or, in the case of ECUs, 
the rate of exchange as published in the Journal, as of the most recent 
available date, or quotations or, in the case of ECUs, rates of exchange from 
one or more major banks in The City of New York or in the country of issue of 
the Foreign Currency in question, which for purposes of the ECU shall be 
Brussels, Belgium, or such other quotations or, in the case of ECU, rates of 
exchange as the Trustee shall deem appropriate.  The provisions of this 
paragraph shall also apply in connection with any other action taken by the 
Holders of Securities pursuant to the terms of this Indenture, including 
without limitation Section 5.1.

          All decisions and determinations of the Trustee regarding the 
Market Exchange Rate or any alternative determination provided for in the 
preceding paragraph shall be in its sole discretion and shall, in the absence 
of manifest error, be conclusive to the extent permitted by law for all 
purposes and irrevocably binding upon the Issuer and all Holders.

          SECTION 11.12  JUDGMENT CURRENCY.  The Issuer agrees, to the 
fullest extent that it may effectively do so under applicable law, that (a) 
if for the purpose of obtaining judgment in any court it is necessary to 
convert the sum due in respect of the principal of or interest on the 
Securities of any series (the "Required Currency") into a currency in which a 
judgment will be rendered (the "Judgment Currency"), the rate of exchange 
used shall be the rate at which, in accordance with normal banking 
procedures, the Trustee could purchase in The City of New York the Required 
Currency with the Judgment Currency on the day on which final unappealable 
judgment is entered, unless such day is not a New York Banking Day, in which 
case, to the extent permitted by applicable law, the rate of exchange used 
shall be the rate at which, in accordance with normal banking procedures, the 
Trustee could purchase in The City of New York the Required Currency with the 
Judgment Currency on the New York Banking Day next preceding the day on which 
final unappealable judgment is entered and (b) its obligations under this 
Indenture and the Securities of such series to make payments in the Required 
currency (i) shall not be discharged or satisfied by any tender, or any 
recovery pursuant to any judgment (whether or not entered in accordance with 
clause (a)), in any currency other than the 


                                   -84-



Required Currency, except to the extent that such tender or recovery shall 
result in the effective receipt by the payee of the full amount of the 
Required Currency expressed to be payable in respect of such payments, (ii) 
shall be enforceable as an alternative or additional cause of action for the 
purpose of recovering in the Required Currency the amount, if any, by which 
such effective receipt shall fall short of the full amount of the Required 
Currency so expressed to be payable and (iii) shall not be affected by 
judgment being obtained for any other sums due under this Indenture.  For 
purposes of the foregoing, "New York Banking Day" means any day except a 
Saturday, Sunday or a legal holiday in The City of New York or a day on which 
banking institutions in The City of New York are authorized or required by 
law or executive order to close.

                                    ARTICLE TWELVE

                      REDEMPTION OF SECURITIES AND SINKING FUNDS

          SECTION 12.1  APPLICABILITY OF ARTICLE.  The provisions of this 
Article shall be applicable to the Securities of any series which are 
redeemable before their maturity or to any sinking fund for the retirement of 
Securities of a series except as otherwise specified as contemplated by 
Section 2.3 for Securities of any series.

          SECTION 12.2  NOTICE OF REDEMPTION; PARTIAL REDEMPTIONS.  Notice of 
redemption to the Holders of Registered Securities of any series to be 
redeemed as a whole or in part shall be given by mailing notice of such 
redemption by first class mail, postage prepaid, at least 30 days and not 
more than 60 days prior to the date fixed for redemption, to such Holders at 
their last addresses as they shall appear upon the registry books for such 
Securities.  Notice of redemption to the Holders of Unregistered Securities 
of any series to be redeemed as a whole or in part, who have filed their 
names and addresses with the Trustee pursuant to Section 4.4(c)(ii), shall be 
given by mailing notice of such redemption by first class mail, postage 
prepaid, at least 30 days and not more than 60 days prior to the date fixed 
for redemption, to such Holders at such addresses as were so furnished to the 
Trustee (and, in the case of any such notice given by the Issuer, the Trustee 
shall make such information available to the Issuer for such purpose).  
Notice of redemption to all other Holders of Unregistered Securities of any 
series shall be published in each Authorized Newspaper with respect to such 
series once in each of three successive calendar weeks, the first publication 
to be not less than 30 days nor more than 60 days prior to the date fixed for 
redemption.  Any notice which is mailed in the manner herein provided shall 
be conclusively presumed to have been duly given, whether or not the Holder 
receives the notice.  Failure to give notice by mail, or 


                                   -85-



any defect in the notice to the Holder of any Security of any series 
designated for redemption as a whole or in part, shall not affect the 
validity of the proceedings for the redemption of any other Security of such 
series.

          The notice of redemption to each such Holder shall specify the 
principal amount of each Security of such series held by such Holder to be 
redeemed, the date fixed for redemption, the redemption price, the place or 
places of payment, that payment will be made upon presentation and surrender 
of such Securities and, in the case of Securities with Coupons attached 
thereto, of all Coupons appertaining thereto maturing after the date fixed 
for redemption, that such redemption is pursuant to the mandatory or optional 
sinking or other analogous fund, or both, if such be the case, that interest 
accrued to the date fixed for redemption will be paid as specified in such 
notice, that on and after said date interest thereon or on the portions 
thereof to be redeemed will cease to accrue (unless the Issuer defaults in 
making such redemption payment or the paying agent is prohibited from making 
such payment pursuant to the terms of this Indenture) and that no 
representation is made as to the correctness or accuracy of the CUSIP number, 
if any, listed in such notice or printed on the Securities.  In case any 
Security is to be redeemed in part only, the notice of redemption shall state 
the portion of the principal amount thereof to be redeemed and shall state 
that on and after the date fixed for redemption, upon surrender of such 
Security, a new Security or Securities of such series in authorized 
denominations for an aggregate principal amount equal to the unredeemed 
portion thereof will be issued.

          The notice of redemption of Securities of any series to be redeemed 
at the option of the Issuer shall be given by the Issuer or, at the Issuer's 
request, by the Trustee in the name and at the expense of the Issuer, in 
which case the Issuer will provide the Trustee with the information required 
to be included in such notice by the preceding paragraph.

          On or before the redemption date specified in the notice of 
redemption given as provided in this Section, the Issuer will deposit with 
the Trustee or with one or more paying agents (or, if the Issuer is acting as 
its own paying agent, set aside, segregate and hold in trust as provided in 
Section 3.4) an amount of money sufficient to redeem on the redemption date 
all the Securities of any series so called for redemption (other than 
Securities or portions of Securities called for redemption which have been 
delivered by the Issuer to the Trustee for cancellation as provided in 
Section 12.5) at the applicable redemption price, together with accrued 
interest to the date fixed for redemption.  The Issuer will deliver to the 
Trustee at least 70 days prior to the date fixed for redemption an Officers' 
Certificate stating the aggregate principal amount of Securities of each 
series and, if applicable, the Tranche (as hereinafter defined) to be 


                                   -86-




redeemed.  In case of a redemption at the option of the Issuer prior to the 
expiration of any restriction on such redemption, the Issuer shall deliver to 
the Trustee, prior to the giving of any notice of redemption to Holders 
pursuant to this Section, an Officers' Certificate stating that such 
restriction has been complied with.  If less than all the Securities of like 
tenor and terms of any series (a "Tranche") are to be redeemed, the Trustee 
shall select the particular Securities of such Tranche to be redeemed pro 
rata or by lot or by a method that complies with the applicable legal and 
securities exchange requirements, if any, and that the Trustee considers fair 
and appropriate and in accordance with the methods generally used at the time 
of selection by fiduciaries in similar circumstances.  Securities may be 
redeemed in part in multiples equal to the minimum authorized denomination 
for Securities of such series or any multiple thereof.  If less than all 
Securities of unlike tenor and terms of a series are to be redeemed, the 
particular Tranche of Securities to be redeemed shall be selected by the 
Issuer.  The Trustee shall promptly notify the issuer in writing of the 
Securities of such series selected for redemption and, in the case of any 
Securities selected for partial redemption, the principal amount thereof to 
be redeemed.  For all purposes of this Indenture, unless the context 
otherwise requires, all provisions relating to the redemption of Securities 
of any series shall relate, in the case of any Security redeemed or to be 
redeemed only in part, to the portion of the principal amount of such 
Security which has been or is to be redeemed.

          SECTION 12.3  PAYMENT OF SECURITIES CALLED FOR REDEMPTION.  If 
notice of redemption has been given as provided in Section 12.2, the 
Securities or portions of Securities specified in such notice shall become 
due and payable on the date and at the place stated in such notice at the 
applicable redemption price, together with interest accrued to the date fixed 
for redemption, and on and after said date (unless the Issuer shall default 
in the payment of such Securities at the applicable redemption price, 
together with interest accrued to said date) interest on the Securities or 
portions of Securities so called for redemption shall cease to accrue, the 
unmatured Coupons, if any, appertaining thereto shall be void and, except as 
provided in Sections 6.5 and 10.4, such Securities shall cease from and after 
the date fixed for redemption to be entitled to any benefit or security under 
this Indenture, and the Holders thereof shall have no right in respect of 
such Securities except the right to receive the applicable redemption price 
thereof and unpaid interest to the date fixed for redemption.  On 
presentation and surrender of such Securities at a place of payment specified 
in said notice, together with all Coupons, if any, appertaining thereto 
maturing after the date fixed for redemption, such Securities or the 
specified portions thereof shall be paid and redeemed by the Issuer at the 
applicable redemption price, together with interest accrued thereon to the 


                                   -87-



date fixed for redemption; provided that payment of interest becoming due on 
or prior to the date fixed for redemption shall be payable, in the case of 
Securities with Coupons attached thereto, to the Holders of the Coupons for 
such interest upon surrender thereof or, in the case of Registered 
Securities, to the Holders of such Registered Securities registered as such 
on the relevant Record Date, subject to the terms and provisions of Sections 
2.3 and 2.7.

          If any Security called for redemption shall not be so paid upon 
surrender thereof for redemption, the principal shall, until paid or duly 
provided for, bear interest from the date fixed for redemption at the rate of 
interest or Yield to Maturity (in the case of an Original Issue Discount 
Security) borne by such Security.

          If any Security with Coupons attached thereto is surrendered for 
redemption and is not accompanied by all appurtenant Coupons maturing after 
the date fixed for redemption, the surrender of such missing Coupon or 
Coupons may be waived by the Issuer and the Trustee, if there be furnished to 
each of them such security or indemnity as they may require to save each of 
them harmless.

          Upon presentation of any Security redeemed in part only, the Issuer 
shall execute and the Trustee shall authenticate and deliver to or on the 
order of the Holder thereof, at the expense of the Issuer, a new Security or 
Securities of such series, of authorized denominations, in principal amount 
equal to the unredeemed portion of the Security so presented.

          SECTION 12.4  EXCLUSION OF CERTAIN SECURITIES FROM ELIGIBILITY FOR 
SELECTION FOR REDEMPTION.  Securities shall be excluded from eligibility for 
selection for redemption if they are identified by registration and 
certificate number in an Officers' Certificate delivered to the Trustee at 
least 40 days prior to the last date on which notice of redemption may be 
given as being owned of record and beneficially by, and not pledged or 
hypothecated by, either (a) the Issuer or (b) an entity specifically 
identified in such Officers' Certificate as directly or indirectly 
controlling or controlled by or under direct or indirect common control with 
the Issuer.

          SECTION 12.5  MANDATORY AND OPTIONAL SINKING FUNDS.  The minimum 
amount of any sinking fund payment provided for by the terms of the 
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 the Securities of any series is herein referred to as an 
"optional sinking fund payment".  The date on which a sinking fund payment is 
to be made is herein referred to as the "sinking fund payment date".


                                   -88-



          In lieu of making all or any part of any mandatory sinking fund 
payment with respect to any series of Securities in cash, the Issuer may at 
its option (a) deliver to the Trustee Securities of such series theretofore 
purchased or otherwise acquired (except upon redemption pursuant to the 
mandatory sinking fund) by the Issuer or receive credit for Securities of 
such series (not previously so credited) theretofore purchased or otherwise 
acquired (except as aforesaid) by the Issuer and delivered to the Trustee for 
cancellation pursuant to Section 2.10, (b) receive credit for optional 
sinking fund payments (not previously so credited) made pursuant to this 
Section or (c) receive credit for Securities of such series (not previously 
so credited) redeemed by the Issuer through any optional redemption provision 
contained in the terms of such series.  Securities so delivered or credited 
shall be received or credited by the Trustee at the sinking fund redemption 
price specified in such Securities.

          On or before the 60th day next preceding each sinking fund payment 
date for any series, the Issuer will deliver to the Trustee an Officers' 
Certificate (which need not contain the statements required by Section 11.5) 
(a) specifying the portion of the mandatory sinking fund payment due on such 
date to be satisfied by payment of cash and the portion to be satisfied by 
credit of Securities of such series and the basis for such credit, (b) 
stating that none of the Securities of such series to be so credited has 
theretofore been so credited, (c) stating that no defaults in the payment of 
interest or Events of Default with respect to such series have occurred 
(which have not been waived or cured) and are continuing and (d) stating 
whether or not the Issuer intends to exercise its right to make an optional 
sinking fund payment on such date with respect to such series and, if so, 
specifying the amount of such optional sinking fund payment which the Issuer 
intends to pay on or before the next succeeding sinking fund payment date.  
Any Securities of such series to be so credited and required to be delivered 
to the Trustee in order for the Issuer to be entitled to credit therefor as 
aforesaid which have not theretofore been delivered to the Trustee shall be 
delivered for cancellation pursuant to Section 2.10 to the Trustee with such 
Officers' Certificate (or reasonably promptly thereafter if acceptable to the 
Trustee).  Such Officers' Certificate shall be irrevocable, and upon its 
receipt by the Trustee the Issuer shall become unconditionally obligated to 
make all the cash payments or other deliveries therein referred to, if any, 
on or before the next succeeding sinking fund payment date.  Failure of the 
Issuer, on or before any such 60th day, to deliver such Officers' Certificate 
and Securities (subject to the parenthetical in the immediately preceding 
sentence) specified in this paragraph, if any, shall not constitute a default 
but shall constitute, on and as of such 60th day, the irrevocable election of 
the Issuer that (i) the mandatory sinking fund payment for such series due on 
the next succeeding sinking fund payment date 


                                   -89-




shall be paid entirely in cash without the option to deliver or credit 
Securities of such series in respect thereof and (ii) the Issuer will make no 
optional sinking fund payment with respect to such series on such date as 
provided in this Section.

          If the sinking fund payment or payments (mandatory or optional or 
both) to be made in cash on the next succeeding sinking fund payment date 
plus any unused balance of any preceding sinking fund payments made in cash 
shall exceed $50,000 (or the equivalent thereof in any Foreign Currency or 
ECU), or any lesser sum in Dollars (or the equivalent thereof in any Foreign 
Currency or ECU), if the Issuer shall so request with respect to the 
Securities of any particular series, such cash shall be applied on the next 
succeeding sinking fund payment date to the redemption of Securities of such 
series at the applicable sinking fund redemption price, together with accrued 
interest to the date fixed for redemption.  If such amount shall be $50,000 
(or the equivalent thereof in any Foreign Currency or ECU) or less and the 
Issuer makes no such request, then such amount shall be carried over until a 
sum in excess of $50,000 (or the equivalent thereof in any Foreign currency 
or ECU) is available.  The Trustee shall select, in the manner provided in 
Section 12.2, for redemption on such sinking fund payment date a sufficient 
principal amount of Securities of such series to absorb said cash, as nearly 
as may be, and shall (if requested in writing by the Issuer) inform the 
Issuer of the serial numbers of the Securities of such series (or portions 
thereof) so selected.  Securities shall be excluded from eligibility for 
redemption under this Section if they are identified by registration and 
certificate number in an Officers' Certificate delivered to the Trustee at 
least 40 days prior to the sinking fund payment date as being owned of record 
and beneficially by, and not pledged or hypothecated by either (a) the Issuer 
or (b) an entity specifically identified in such Officers' Certificate as 
directly or indirectly controlling or controlled by or under direct or 
indirect common control with the Issuer.  The Trustee, in the name and at the 
expense of the Issuer (or the Issuer, if it shall so request the Trustee in 
writing), shall cause notice of redemption of the Securities of such series 
to be given in substantially the manner provided in Section 12.2 (and with 
the effect provided in Section 12.3) for the redemption of Securities of such 
series in part at the option of the Issuer.  The amount of any sinking fund 
payments not so applied or allocated to the redemption of Securities of such 
series shall be added to the next cash sinking fund payment for such series 
and, together with such payment, shall be applied in accordance with the 
provisions of this Section.  Any and all sinking fund moneys held on the 
stated maturity date of the Securities of a particular series (or earlier, if 
such maturity is accelerated), which are not held for the payment or 
redemption of particular Securities of such series, shall be applied, 
together with other moneys, if necessary, sufficient for the purpose, to the 
payment of the 


                                   -90-



principal of and interest on the Securities of such series at maturity.

          Unless otherwise provided for, on or before each sinking fund 
payment date, the Issuer shall pay to the Trustee in cash or shall otherwise 
provide for the payment of all interest accrued to the date fixed for 
redemption on Securities to be redeemed on such sinking fund payment date.
  
          The Trustee shall not redeem or cause to be redeemed Securities of 
any series with sinking fund moneys or give any notice of redemption of 
Securities of such series by operation of the sinking fund for such series 
during the continuance of a default in the payment of interest on the 
Securities of such series or of any Event of Default with respect to such 
series except that, if notice of redemption of any Securities of such series 
shall theretofore have been given, the Trustee shall redeem or cause to be 
redeemed such Securities, provided that the Trustee or one or more paying 
agents shall have received from the Issuer a sum sufficient for such 
redemption.  Except as aforesaid, any moneys in the sinking fund for such 
series at the time when any such default or Event of Default shall occur, and 
any moneys thereafter paid into the sinking fund, shall, during the 
continuance of such default or Event of Default, be deemed to have been 
collected under Article Five and held for the payment of all Securities of 
such series.  In case such Event of Default shall have been waived as 
provided in Section 5.10 or the default cured on or before the 60th day 
preceding any sinking fund payment date, such moneys shall thereafter be 
applied on such sinking fund payment date in accordance with this Section to 
the redemption of Securities of such series.
