     SECTION 2.01.  FORM AND DATING.  The Securities of each series shall be 
in such form as shall be established by or pursuant to a Board Resolution or 
in one or more indentures supplemental hereto, with such appropriate 
insertions, omissions, substitutions and other variations as are required or

by law, stock exchange rules or usage.

     Each Security shall be in fully-registered form and shall be dated the

     rates of interest and the date or dates from which such interest shall 
     accrue; 

        (5)  the Interest Payment Dates on which such interest shall be payable
     and the Regular Record Dates for the interest payable on any Interest 
     Payment Date;

        (6)  the place or places where the Principal of and interest on the
     Securities of such series shall be payable;

     within which, the price or prices at which, and the terms and conditions 
     upon which Securities shall be redeemed or purchased, in whole or in part,

                                   -8- 



        (9)  if other than denominations of $1,000 and any integral multiple
     thereof, the denominations in which Securities shall be issuable;

        (10) if Securities of such series constitute Original Issue Discount
     Securities, the portion of the principal amount of Securities which shall
     be payable upon declaration of acceleration thereof pursuant to Section 
     6.02;

        (11) any Events of Default with respect to the Securities of such series
     in addition to those set forth in Section 6.01;

        (14) any other terms with respect to the Securities of such series 
     (which terms shall not be inconsistent with the provisions of this 
     Indenture).

     All Securities of any one series shall be substantially identical except 
as to denomination and except as may otherwise be provided by or pursuant to 
the Board Resolution and set forth in the Officers' Certificate delivered to 
the Trustee or as provided pursuant to an indenture supplemental hereto with 
respect to such series.  All Securities of any one series need not be issued 
at the same time, and unless otherwise provided, a series may be reopened for 
issuance of additional Securities of such series.

Securities for the Company by manual or facsimile signature and the Company's 
seal shall be reproduced on the Securities and attested by the manual or 
facsimile signature of an authorized Officer of the Company.

     If an Officer whose signature is on a Security no longer holds that 
office at the time the Security is authenticated, the Security shall be valid 
nevertheless.

     A Security shall not be valid until authenticated by the Trustee by 
manual signature. The Trustee's certificate of authentication of all 
Securities shall be in substantially the following form: 

                                   -9- 



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

                                       _________________________, as Trustee 

                                                By:_________________________ 
                                                     Authorized Signatory    


     The manual signature of the Trustee on a certificate of authentication 
in the form hereinabove provided for shall be conclusive evidence that the 
Security has been authenticated under this Indenture.

     The Trustee shall at any time and from time to time authenticate 
Securities for original issue, upon delivery to the Trustee of (i) the 
Securities executed by the Company and (ii) a Company Order requesting the 
authentication thereof.

     In authenticating Securities of a particular series, and accepting the 
additional responsibilities under this Indenture in relation to such series 
of Securities, the Trustee shall be entitled to receive and (subject to 
Section 7.01) shall be fully protected in relying upon:

        (1)  certified copies of the Certificate of Incorporation and bylaws of 
     the Company;

        (2)  each Board Resolution relating to the Securities of such series, 
     and if the form or forms of the Securities of such series and the terms 
     with respect thereto are established by a Board Resolution, an Officers' 
     Certificate (i) approving the form or forms of the Securities of such 
     series and the terms with respect thereto, to the extent such terms have
     been established (and, if the Securities of such series are Original Issue
     Discount Securities, setting forth such facts as are necessary to compute 
     amounts due upon acceleration, if such facts are not specified in the form
     of Security) and (ii) stating that all conditions precedent to the issuance
     and authentication of the Securities of such series have been complied 
     with;

        (3)  an executed supplemental indenture (if any) relating to such 
     Securities; 

        (4)  an Opinion of Counsel, which shall state

             (a)  that the terms with respect to the Securities of such series
        have been established by or pursuant to a Board Resolution or by a

                                   -10- 



        supplemental indenture as permitted by, and in conformity with, the
        provisions of this Indenture;

             (b)  that the Securities of such series, when authenticated and
        delivered by the Trustee and issued by the Company in the manner and
        subject to any further conditions specified in such Opinion of Counsel 
        that are reasonably acceptable to the Trustee, will constitute valid and
        binding obligations of the Company, enforceable against the Company in 
        accordance with their terms, except insofar as (i) such enforcement may
        be subject to bankruptcy, insolvency, reorganization, moratorium or 
        other similar laws now or hereafter in effect relating to creditors' 
        rights generally and (ii) the remedy of specific performance and 
        injunctive and other forms of equitable relief may be subject to 
        equitable defenses and to the discretion of the court before which any 
        proceeding therefor may be brought; and

             (c)  that all conditions precedent to the execution and delivery by
        the Company of the Securities have been complied with; and

        (5)  such other documents as the Trustee may reasonably require.

     If all Securities of a series are not to be originally issued at one 
time, it shall not be necessary to deliver the Officers' Certificate or the 
Opinion of Counsel otherwise required pursuant to Section 2.01 and this 
Section 2.02 at or prior to the time of authentication of each Security of 
such series if such documents have been delivered at or prior to the 
authentication upon original issuance of the first Security of such series.

     Each security shall be dated the date of its authentication.

     The Trustee shall not be required to authenticate any Securities if such 
action may not lawfully be taken or will affect the Trustee's own rights, 
duties or immunities under the Securities and this Indenture in a manner 
which is not reasonably acceptable to the Trustee.

     The aggregate principal amount of Securities of any series outstanding 
at any time may not exceed any limit upon the maximum principal amount for 
such series set forth in or pursuant to the Board Resolution or supplemental 
indenture relating to such series delivered pursuant to this Section 2.02, 
except as authorized pursuant to Section 2.07.

     The Trustee may appoint an authenticating agent acceptable to the 
Company to authenticate Securities.  An authenticating agent may authenticate 
Securities whenever the 

                                   -11- 



Trustee may do so, provided that only the Trustee may authenticate Securities 
pursuant to Section 2.07. Each reference in this Indenture to authentication 
by the Trustee includes authentication by an authenticating agent.  An 
authenticating agent has the same rights as an Agent to deal with the Company 
or an Affiliate.

     SECTION 2.03.  REGISTRAR AND PAYING AGENT.  The Company shall maintain an
office or agency where Securities may be presented to the registrar
("Registrar") for registration of transfer or for exchange and an office or
agency where Securities may be presented to the paying agent ("Paying Agent")
for payment; provided, however, that at the option of the Company payment of
interest may be made by check mailed to the address of the person entitled
thereto as such address shall appear in the register of the Securities
provided for in this Section.  The Registrar shall keep a register of the
Securities (the "Security Register") and of their transfer and exchange.  The
Company may appoint one or more co-registrars and one or more additional
paying agents with respect to any one or more series. The "Registrar" includes
any co-registrar and the term "Paying Agent" includes any additional paying
agent.  The Company shall notify the Trustee of the name and address of any
Registrar or Paying Agent not a party to this Indenture.  If the Company fails
to maintain a Registrar or Paying Agent for the Securities, the Trustee shall
act as such.  The Company initially appoints the Trustee as Paying Agent and
Registrar.

     SECTION 2.04.  PAYING AGENT TO HOLD MONEY IN TRUST.  The Company shall 
require each Paying Agent other than the Trustee to agree in writing that the 
Paying Agent will (i) hold in trust for the benefit of Securityholders of any 
series or the Trustee all money held by the Paying Agent for the payment of 
Principal of or interest on the Securities of such series, (ii) notify the 
Trustee of any default by the Company in making any such payment and (iii) 
pay to the Trustee all sums so held in trust by such Paying Agent, upon 
written request of the Trustee at any time during the continuance of an Event 
of Default.  If the Company acts as Paying Agent, it shall segregate the 
money and hold it as a separate trust fund.  The Company at any time may 
require a Paying Agent to pay all money held by it to the Trustee.  Upon 
doing so, the Paying Agent (if other than the Company) shall have no further 
liability for the money.

     SECTION 2.05.  SECURITYHOLDER LISTS.  The Trustee shall preserve in as 
current a form as is reasonably practicable the most recent list available to 
it of the names and addresses of Holders of Securities of each series.  If 
the Trustee is not the Registrar and Paying Agent with respect to Securities 
of any series, the Company shall furnish to the Trustee on or before each 
Interest Payment Date for such Securities (and on dates to be determined in 
the manner provided in Section 2.01 for any series of Original Issue Discount 
Securities which by their terms bear interest only after Maturity), but in no 
case less frequently than semiannually, and at such other times as the 
Trustee may request in writing, 

                                   -12- 



a list in such form and as of such date as the Trustee may reasonably require 
of the names and addresses of Holders of the Securities of such series.

     SECTION 2.06.  TRANSFER AND EXCHANGE.  Subject to the provisions of 
Section 2.10, where Securities are presented to the Registrar with a request 
to register transfer or to exchange them for an equal principal amount of 
Securities of the same series of other denominations, the Registrar shall 
register the transfer or make the exchange if its requirements for such 
transactions are met.  The Registrar shall not be required to register the 
transfer or exchange of (i) Securities of any series during a 15-day period 
beginning at the opening of business 15 days before the day of mailing of a 
redemption notice pursuant to Section 3.03 with respect to Securities of such 
series or (ii) any Security selected for redemption in whole or in part, 
except the unredeemed portion of a Security redeemed in part.  To permit 
registration of transfer and exchanges, the Company shall issue and the 
Trustee shall authenticate Securities at the Registrar's request.  No service 
charge shall be made to any Securityholder for any transfer, exchange or 
replacement of Securities, except that the Company may require payment of a 
sum sufficient to cover any tax or other governmental charge which may be 
imposed in relation to any such transfer, exchange or replacement, other than 
exchanges pursuant to Section 2.10, 3.06 or 9.05. Notwithstanding the 
foregoing, Securities of a series may be exchanged only for Securities of the 
same series having identical terms.


     Prior to due presentment of a Security for registration of transfer, the 
Company, the Trustee and any agent of the Company or the Trustee may treat 
the person in whose name such Security is registered as the owner of such 
Security for the purpose of receiving payment of Principal of and any 
interest on such Security and for all other purposes whatsoever, whether or 
not such Security be overdue, and neither the Company, the Trustee nor any 
agent of the Company or the Trustee shall be affected by notice to the 
contrary.


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

     SECTION 2.07.  REPLACEMENT SECURITIES.  If the Holder of a Security 
claims that the Security has been lost, mutilated, destroyed or wrongfully 
taken, the Company shall issue and the Trustee shall authenticate a 
replacement Security of the same series having identical terms if the 
Trustee's requirements are met.  If required by the Trustee or the Company, 
such Holder shall provide an indemnity bond sufficient in the judgment of the 
Trustee to protect the Company, the Trustee, any Agent or any authenticating 
agent from any loss which any of them may suffer if a Security is replaced.

                                   -13- 




     Every replacement Security is an additional obligation of the Company 
and shall be entitled to all benefits of the Indenture equally and 
proportionately with all other Securities duly issued hereunder.

     SECTION 2.08.  OUTSTANDING SECURITIES.  The Securities outstanding at 
any time are all the Securities authenticated by the Trustee, except for 
those cancelled by it, those delivered to it for cancellation, and those 
described in this Section as not outstanding.

     If a Security is replaced pursuant to Section 2.07, it ceases to be 
outstanding unless the Trustee receives proof satisfactory to it that the 
replaced Security is held by a bona fide purchaser.

     If Securities are considered paid under Section 4.01, they cease to be 
outstanding and interest on them ceases to accrue.

     A Security does not cease to be outstanding because the Company or an 
Affiliate holds the Security.

     SECTION 2.09.  REQUIRED PRINCIPAL AMOUNT.  In determining whether the 
Holders of the required principal amount of Securities have concurred in any 
direction, waiver or consent, (i) Securities owned by the Company or an 
Affiliate shall be disregarded, except that for the purpose of determining 
whether the Trustee shall be protected in relying on any such direction, 
waiver or consent, only Securities which the Trustee has been advised in 
writing by the Company or the Holder are so owned shall be so disregarded and 
(ii) the principal amount of an Original Issue Discount Security that shall 
be deemed to be outstanding for such purposes shall be the amount of the 
principal thereof that would be due and payable as of the date of such 
determination upon a declaration of acceleration of the Stated Maturity 
thereof determined in accordance with Section 6.02.


     SECTION 2.10.  TEMPORARY SECURITIES; GLOBAL SECURITIES. (a) Until 
definitive Securities are ready for delivery, the Company may prepare and 
execute and, upon receipt of a Company Order, the Trustee shall authenticate 
temporary Securities.  Temporary Securities of any series shall be 
substantially in the form of definitive Securities of such series but may 
have variations that the Company considers appropriate for temporary 
Securities.  Without unreasonable delay, the Company shall prepare and, upon 
surrender of such temporary Securities, the Company shall execute and the 
Trustee shall authenticate definitive Securities of such series in exchange 
for such temporary Securities.  Until so exchanged, the temporary Securities 
shall in all respects be entitled to the same benefits under this Indenture as 
definitive Securities of such series.



                                     -14-



     (b)  If the Company shall establish pursuant to Section 2.01 that the 
Securities of a series are to be issued in whole or in part in the form of 
one or more Global Securities, then the Company shall execute and the Trustee 
shall, in accordance with Section 2.02 and pursuant to a Company Order, 
authenticate and deliver one or more Global Securities in temporary or 
permanent form that (i) shall represent and shall be denominated in an amount 
equal to the aggregate principal amount of the outstanding Securities of such 
series to be represented by one or more Global Securities, (ii) shall be 
registered in the name of the Depositary for such Global Security or 
Securities or the nominee of such Depositary, (iii) shall be delivered by the 
Trustee to such Depositary or pursuant to such Depositary's instruction and 
(iv) shall bear any customary legend reasonably required by the Depositary 
and shall further bear a legend substantially to the following effect: "This 
Security is a Global Security within the meaning of the Indenture hereinafter 
referred to and is registered in the name of a Depositary or a nominee 
thereof.  This Security may not be transferred to, or registered or exchanged 
for Securities registered in the name of, any person other than the 
Depositary or a nominee thereof and no such transfer may be registered, 
except in the limited circumstances described in the Indenture.  Every 
Security authenticated and delivered upon registration of transfer of, or in 
exchange for or in lieu of, this Security shall be a Global Security subject 
to the foregoing, except in such limited circumstances."

     Notwithstanding any other provision of this Section 2.10 or Section 
2.06, unless and until it is exchanged in whole or in part for Securities in 
definitive form, a 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 series 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 
series or a nominee of such successor Depositary.

     None of the Company, the Trustee, any Paying Agent or the Registrar has 
any direct obligation or responsibility to participants of the Depositary or 
beneficial owners of interests in Securities.  Without limiting the 
generality of the foregoing, none of the Company, the Trustee, any Paying 
Agent or the Registrar will have any responsibility or liability for any 
aspect of the records relating to or payments made on account of beneficial 
ownership interests in a Global Security (including the maintenance, review 
and supervision of any such records), for the delivery of any notice to any 
owner of a beneficial interest, for the selection of the beneficial owners to 
receive payment in the event of any partial redemption of Securities, or for 
any consent given or other action taken by the Depositary as owner of the 
Securities.

     If at any time the Depositary for the Securities of a series notifies 
the Company that it is unwilling or unable to continue as Depositary for the 
Securities of such series or if at any time the Depositary for Securities of 
a series shall no longer be registered or in good 


                                      -15-



standing under the Exchange Act or other applicable statute or regulation, 
the Company shall appoint a successor Depositary with respect to the 
Securities of such series.  If a successor Depositary for the Securities of 
such series is not appointed by the Company within 90 days after the Company 
receives such notice or becomes aware of such condition, the Company will 
execute, and the Trustee, upon receipt of a Company Order instructing the 
Trustee to authenticate and deliver definitive Securities of such series, 
will authenticate and deliver Securities of such series in definitive form in 
an aggregate principal amount equal to the principal amount of the Global 
Security or Securities representing such series in exchange for such Global 
Security or Securities.

     The Company may at any time and in its sole discretion determine that 
the Securities of any series issued in the form of one or more Global 
Securities shall no longer be represented by such Global Security or 
Securities. Furthermore, if there shall have occurred and be continuing an 
Event of Default or an event which, with the giving of notice or lapse of 
time, or both, would constitute an Event of Default with respect to any 
series of Securities, the Trustee may determine that the Securities of such 
series shall no longer be represented by a Global Security or Securities. In 
any such event, the Company will execute, and the Trustee, upon receipt of a 
Company Order instructing the Trustee to authenticate and deliver definitive 
Securities of such series, will authenticate and deliver Securities of such 
series in definitive form in an aggregate principal amount equal to the 
principal amount of the Global Security or Securities representing such 
series in exchange for such Global Security or Securities.

     If specified by the Company pursuant to Section 2.01 with respect to 
Securities of a series, the Depositary for such series of Securities may 
surrender a Global Security for such series of Securities in exchange, in 
whole or in part, for Securities of such series in definitive form on such 
terms as are acceptable to the Company and such Depositary. Thereupon, the 
Company shall execute and, upon receipt of a Company Order, the Trustee shall 
authenticate and deliver, without charge:

          (i)  to each person specified by the Depositary, a new Security or 
     Securities of the same series of any authorized denomination as 
     requested by such person in an aggregate principal amount equal to and 
     in exchange for such person's beneficial interest in the Global 
     Security; and

         (ii) to the Depositary, a new Global Security in a denomination 
     equal to the difference, if any, between the principal amount of the 
     surrendered Global Security and the aggregate principal amount of 
     Securities delivered to Holders thereof.


                                      -16-



     Upon the exchange of a Global Security for Securities in definitive 
form, such Global Security shall be cancelled by the Trustee.  Securities 
issued in exchange for a Global Security pursuant to this Section shall be 
registered in such names and in such authorized denominations as the 
Depositary for such Global Security, pursuant to instructions from its direct 
or indirect participants or otherwise, shall instruct the Trustee.  The 
Trustee shall deliver such Securities to the persons in whose names such 
Securities are so registered.

     SECTION 2.11.  CANCELLATION.  The Company at any time may deliver 
Securities of any series to the Trustee for cancellation.  The Registrar and 
Paying Agent shall forward to the Trustee any Securities surrendered to them 
for registration of transfer, exchange or payment.  The Trustee shall cancel 
all Securities surrendered for registration of transfer, exchange, payment or 
cancellation and shall destroy or otherwise dispose of, or retain in 
accordance with its standard retention policy, at its discretion, canceled 
Securities and, where applicable, deliver a certificate of such destruction 
or retention to the Company.  The Company may not issue new Securities of any 
series to replace Securities of such series that it has paid or delivered to 
the Trustee for cancellation.

     SECTION 2.12.  DEFAULTED INTEREST.  If the Company defaults in a payment 
of interest on any of the Securities, it shall pay the defaulted interest 
plus, to the extent permitted by law, any interest payable on the defaulted 
interest, to the persons who are Holders of such Securities on a subsequent 
special record date.  The Company shall fix the record date and payment date 
after making arrangements satisfactory to the Trustee for the deposit of such 
amounts with the Trustee for payment and after consultation with the Trustee 
regarding the selection of such dates.  At least 15 days before the record 
date, the Company shall mail to the Holders of such Securities a notice that 
states the record date, payment date, and amount of interest to be paid.

                                  ARTICLE 3

                          REDEMPTION; SINKING FUND


     SECTION 3.01.  NOTICES TO TRUSTEE.  The Company may elect to redeem 
Securities of any series in accordance with the provisions of such 
Securities; provided, however, that if an Event of Default shall have 
occurred and be continuing, the Securities of any series may not be redeemed 
in whole or in part, unless (i) the Securities of all series are redeemed in 
whole or (ii) the Securities of all series are redeemed in part and the 
principal amount to be redeemed is prorated among all Holders so that all 
Holders of each series receive in redemption of their outstanding Securities 
the same principal amount per $1,000 of Securities (provided, however, that 
if the Securities of any such series are Original Issue 


                                      -17-



Discount Securities, for purposes of this clause (ii), such pro ration shall 
be based upon each $1,000 that would be due and payable on the redemption 
date in the event of a declaration of acceleration of the Stated Maturity 
thereof pursuant to Section 6.02).  The election of the Company to redeem 
Securities of any series in accordance with the provisions of such Securities 
shall be evidenced by or pursuant to a Board Resolution.  In case of any 
redemption at the election of the Company, the Company shall, at least 45 
days before the redemption date (unless a shorter notice shall be 
satisfactory to the Trustee), notify the Trustee of such redemption date and 
in the case of any redemption of less than all of the Securities of any 
series (or, where redemption provisions of any series of Securities are not 
identical as to each Security within the series, in case of any redemption at 
the election of the Company of less than all the Securities with identical 
redemption provisions) the principal amount of the Securities of such series 
to be redeemed and shall deliver to the Trustee such documentation and 
records as shall enable the Trustee to select the Securities to be redeemed 
pursuant to Section 3.02.

     SECTION 3.02.  SELECTION OF SECURITIES TO BE REDEEMED.  If less than all 
of the Securities of a series (or, where the redemption provisions of any 
series of Securities are not identical as to each Security within the series, 
if less than all the Securities with identical redemption provisions) are to 
be redeemed, the Trustee shall, subject to Section 3.01, select the 
Securities to be redeemed by such method as the Trustee shall deem fair and 
appropriate.  The Trustee shall make the selection not more than 45 days 
before the redemption date from outstanding Securities of such series (or, if 
the redemption provisions of all of the Securities of such series are not 
identical, from Securities of such series with identical redemption 
provisions) not previously called for redemption.  The Trustee may select for 
redemption portions of the principal of Securities of any series that have 
denominations larger than the minimum principal denomination for such series. 
Provisions of this Indenture that apply to Securities called for redemption 
also apply to portions of Securities called for redemption.

     SECTION 3.03.  NOTICE OF REDEMPTION.  At least 30 days but not more than 
60 days before a redemption date, the Trustee shall, in the name of the 
Company and at the Company's expense, mail by first-class mail a notice of 
redemption to each Holder at the address shown in the Security Register whose 
Securities are to be redeemed.

     The notice shall identify the Securities to be redeemed and shall state:

          (1)  the redemption date;

          (2)  the redemption price;

          (3)  the name and address of the Paying Agent;


                                      -18-



             (4)  if less than all the outstanding Securities of a series 
     (or, in the case of series of Securities in which the redemption 
     provisions are not identical as to each Security within the series, less 
     than all of the Securities of a series with identical redemption 
     provisions) are to be redeemed, the identification (and, in the case of 
     partial redemption, the principal amounts) of the particular Securities 
     to be redeemed;
     
             (5)  that Securities called for redemption must be surrendered 
     to the Paying Agent to collect the redemption price;
     
             (6)  that interest on Securities called for redemption ceases to 
     accrue on and after the redemption date; and
     
             (7)  that the redemption is pursuant to the terms of a sinking 
     fund, if such is the case.

     SECTION 3.04.  EFFECT OF NOTICE OF REDEMPTION.  Once notice of a 
redemption is mailed, Securities called for redemption become due and 
payable on the redemption date at the redemption price.  Upon surrender 
to the Paying Agent, such Securities shall be paid and redeemed at the 
redemption price, together with interest accrued thereon to the 
redemption date; provided, however, that installments of interest 
becoming due on or prior to the redemption date shall be payable to the 
Holders of such Securities, or one or more previous Securities 
evidencing all or a portion of the same debt as that evidenced by such 
particular Securities, registered as such at the close of business on 
the relevant record date according to their terms and the provisions of 
Section 2.12.

     SECTION 3.05.  DEPOSIT OF REDEMPTION PRICE.  On or before the 
redemption date, the Company shall deposit with the Paying Agent money 
in immediately available funds sufficient to pay the aggregate 
redemption price of and accrued interest on all Securities to be 
redeemed on that date.

     SECTION 3.06.  SECURITIES REDEEMED IN PART.  Upon surrender of a 
Security that is redeemed in part, the Company shall execute and the 
Trustee shall authenticate for the Holder a new Security of the same 
series, having terms identical to those of the Securities surrendered, 
equal in principal amount to the unredeemed portion of the Security 
surrendered.

     SECTION 3.07.  SINKING FUND.  Each sinking fund payment provided 
for by the terms of Securities of any series shall be applied to the 
redemption of such Securities as provided for by the terms of such 
Securities and this Section 3.07.


                                      -19-



     In satisfaction of any minimum or optional sinking fund payment 
required or permitted to be made pursuant to the terms of Securities of 
any particular series (or, where the sinking fund provisions of each 
Security within such series are not identical, then pursuant to the 
terms of the Securities with identical sinking fund provisions), the 
Company may (i) deliver to the Trustee Securities of that series (or, 
where the sinking fund provisions of the Securities of such series are 
not identical, Securities of that series having identical sinking fund 
provisions) which have not previously been called for redemption and 
which the Company has not previously delivered to the Trustee for 
cancellation or (ii) notify the Trustee of its election to credit 
against the required sinking fund payment the principal amount of any 
Securities of that series (or, if applicable, any Securities of that 
series with identical sinking fund provisions) which have been redeemed 
otherwise than pursuant to minimum sinking fund payment requirements 
with respect to the Securities of such series (or, if applicable, with 
respect to the Securities of such series with identical sinking fund 
provisions); provided, however, that such Securities have not been 
previously so credited. Such Securities shall be received and credited 
for such purpose by the Trustee at the redemption price specified in 
such Securities for redemption through operation of the sinking fund and 
the amount of such minimum or optional sinking fund payment shall be 
reduced accordingly.

     Not less than 45 days prior to each sinking fund payment date 
(unless a shorter notice shall be satisfactory to the Trustee) for any 
particular series of Securities (or, where the sinking fund provisions 
of the Securities within such series are not identical, for the 
Securities of such series having identical sinking fund provisions), the 
Company will give an Officer's Certificate to the Trustee specifying the 
amount of the next succeeding sinking fund payment (including any 
optional sinking fund payment which is permitted to be made by the terms 
of the Securities) for that series pursuant to the terms of that series 
(or, if applicable, for such Securities pursuant to the terms of such 
Securities), the portion thereof, if any, which is to be satisfied by 
payment of cash and the portion thereof, if any, which is to be 
satisfied by crediting Securities against the required sinking fund 
payment pursuant to the preceding paragraph of this Section and will 
also deliver to the Trustee any Securities to be so credited.  The 
Trustee shall select the Securities to be redeemed upon such sinking 
fund payment date in the manner specified in Section 3.02 and cause 
notice of the redemption thereof to be given in the name of and at the 
expense of the Company in the manner provided in Section 3.03. Such 
notice having been duly given, the redemption of such Securities shall 
be made upon the terms and in the manner stated in Sections 3.04 and 
3.06.

     SECTION 3.08.  TERMS OF SECURITIES TO GOVERN.  Notwithstanding any 
other provision of this Article 3, if any provision of any Security of 
any series shall conflict with any provision of this Article, the 
provision of such Security shall govern.


                                      -20-



                                  ARTICLE 4

                                  COVENANTS


     SECTION 4.01.  PAYMENT OF SECURITIES.  The Company shall pay the 
Principal of and any interest on the Securities on the dates and in the 
manner provided in the Securities. Principal and interest shall be considered 
paid on the date due if the Paying Agent holds on that date money deposited 
with it by or on behalf of the Company sufficient to pay all Principal and 
interest then due.


     The Company shall pay interest on overdue principal at the rate borne by 
such Securities or otherwise as provided in the Securities; it shall pay 
interest on overdue installments of interest at the same rate to the extent 
permitted by law.

     Each payment by the Company to the Trustee or the Paying Agent shall be 
accompanied by a written notice from the Company that specifies the series to 
which such payment relates.

     SECTION 4.02.  SEC REPORTS.  The Company shall furnish to the Trustee, 
within 15 days after it files them with the SEC, 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 SEC may by rules and regulations 
prescribe) that the Company is required to file with the SEC pursuant to 
Section 13 or 15(d) of the Exchange Act.  The Company also shall comply with 
the other provisions of TIA SECTION 314(a).

     SECTION 4.03.  RESTRICTION ON CREATION OF SECURED DEBT.  After the date 
hereof, the Company will not at any time create, incur, assume or guarantee, 
and will not cause or permit a Restricted Subsidiary to create, incur, assume 
or guarantee, any Secured Debt (including the creation of Secured Debt by the 
securing of existing indebtedness) without first making effective provision 
(and the Company covenants that in such case it will first make or cause to 
be made effective provision) whereby the Securities of all series then 
outstanding (together with any other indebtedness of the Company or such 
Restricted Subsidiary then entitled to be so secured) shall be secured 
equally and ratably with (or prior to) any and all other obligations and 
indebtedness thereby secured, for so long as any such other obligations and 
indebtedness shall be so secured; provided, however, that the foregoing 
covenants shall not be applicable to Secured Debt secured solely by one or 
more of the following Security Interests:

          (a)  Any Security Interest upon any property which consists solely of
     one or more parcels of real property, manufacturing plants, warehouses or
     office buildings and of fixtures and equipment located on or at such 
     parcels, plants, 


                                   -21-



     warehouses or buildings and which is acquired, constructed, developed or 
     improved by the Company or a Restricted Subsidiary after the date hereof,
     which Security Interest is created prior to or contemporaneously with, 
     or within 120 days after, (i) in the case of the acquisition of such 
     property, the completion of such acquisition and (ii) in the case of the
     construction, development or improvement of such property, the later to 
     occur of the completion of such construction, development or improvement
     or the commencement of operation, use or commercial production (exclusive
     of test and start-up periods) of the property, which Security Interest 
     secures or provides for the payment of all or any part of the acquisition
     cost of such property or the cost of construction, development or 
     improvement thereof, as the case may be;

          (b)  Any Security Interest on property existing at the time of the
     acquisition thereof by the Company or a Restricted Subsidiary, which 
     Security Interest secures obligations assumed by the Company or a 
     Restricted Subsidiary;

          (c)  Any Security Interest existing on the property of a corporation
     or firm at the time such corporation or firm is merged into or consolidated
     with the Company or a Restricted Subsidiary; 

          (d)  Any conditional sales agreement or other title retention 
     agreement with respect to any property acquired by the Company or a 
     Restricted Subsidiary;

          (e)  Any Security Interest to secure indebtedness of a Restricted
     Subsidiary to the Company or to another Restricted Subsidiary; or
   
          (f)  Any extension, renewal or refunding (or successive extensions,
     renewals or refundings) in whole or in part of any Secured Debt secured by 
     any Security Interest referred to in the foregoing subparagraphs (a) 
     through (e), inclusive; provided, however, that the principal amount of 
     the Secured Debt secured thereby shall not exceed the principal amount 
     outstanding immediately prior to such extension, renewal or refunding and 
     that the Security Interest securing such Secured Debt shall be limited to 
     the property which, immediately prior to such extension, renewal, or 
     refunding, secured such Secured Debt and additions to such property.

     Notwithstanding subparagraphs (b) and (c) above, the creation, 
incurrence, assumption or guarantee of any Secured Debt described therein 
shall not be permitted (i) if such Secured Debt was created, incurred, 
assumed or guaranteed in contemplation of the event or transaction referred 
to in said subparagraphs or (ii) if the Security Interest securing such 
Secured Debt attaches to or affects property owned by the Company or a 
Restricted Subsidiary prior to the event or transaction referred to in said 
subparagraphs.


                                   -22-




     Notwithstanding anything to the contrary in this Section 4.03, the 
Company and any one or more Restricted Subsidiaries may create, incur, assume 
or guarantee Secured Debt if immediately thereafter the sum of (i) the 
aggregate principal amount of all Secured Debt outstanding as of the date of 
determination (excluding Secured Debt permitted to be created, incurred, 
assumed or guaranteed pursuant to subparagraphs (a) through (f), inclusive, 
above) and (ii) all Attributable Debt in respect of Sale and Leaseback 
Transactions as of the date of determination would not exceed 10% of 
Consolidated Net Tangible Assets.

     SECTION 4.04.  RESTRICTION ON SALE AND LEASEBACK TRANSACTIONS. After the 
date hereof, the Company will not, and will not permit any Restricted 
Subsidiary to, enter into any Sale and Leaseback Transaction, unless (a) the 
Company or such Restricted Subsidiary would be entitled to incur Secured Debt 
pursuant to Section 4.03 (other than by reason of the provisions of 
subparagraphs (a) through (f), inclusive, of said Section) in an amount equal 
to the Attributable Debt in respect of such Sale and Leaseback Transaction 
without equally and ratably securing the Securities as provided in said 
Section or (b) each of the following conditions is satisfied: (i) the Company 
shall promptly give notice of such sale or transfer to the Trustee; (ii) the 
net proceeds of such sale or transfer are at least equal to the fair value 
(as determined in good faith by a Board Resolution, a copy of which has been 
delivered by the Company to the Trustee) of the property which is the subject 
of such sale or transfer; and (iii) the Company or a Restricted Subsidiary 
shall apply, within one year after the effective date of such sale or 
transfer, or shall have committed within one year after such effective date 
to apply, an amount at least equal to the net proceeds of the sale or 
transfer of the property which is the subject of such sale or transfer to the 
optional redemption of Securities in accordance with the provisions of 
Article 3 at the redemption price applicable at the time of such redemption, 
or to the repayment of other Funded Debt owing by the Company or any 
Restricted Subsidiary which is not subordinate and junior in right of payment 
to the Securities, or in part to such redemption and in part to such 
repayment; provided, however, that if pursuant to clause (b) above the 
Company commits to apply an amount at least equal to the net proceeds of a 
sale or transfer to the redemption of the Securities or to the repayment of 
other Funded Debt, such commitment shall be made in a written instrument 
delivered by the Company to the Trustee and shall require the Company to so 
apply said amount within 18 months after the effective date of such sale or 
transfer, and it shall constitute a breach of the provisions of this Section 
4.04 if the Company shall fail so to apply said amount in satisfaction of 
such commitment; and, provided, further, that in lieu of applying an amount 
equal to all or part of such net proceeds to such redemption or repayment, 
the Company may, within one year after such sale or transfer, deliver to the 
Trustee Securities (other than Securities made the basis of a reduction in 
any mandatory sinking fund payment under the terms of the Securities of any 
series) for cancellation and thereby reduce the amount to be applied to the 
redemption of Securities pursuant to clause (b) above by an amount equal to 
the aggregate principal amount of Securities so delivered.  Securities 
redeemed or delivered to the Trustee for cancellation



                                   -23-




pursuant to this Section 4.04 shall not be used as credits against mandatory 
sinking fund payments.

     SECTION 4.05.  CERTIFICATE TO TRUSTEE. The Company covenants and agrees 
to furnish to the Trustee, not less often than annually, an Officer's 
Certificate certifying as to the Company's compliance with all conditions and 
covenants under this Indenture; provided, for purposes of this paragraph, 
such compliance shall be determined without regard to any period of grace or 
requirement of notice provided under this Indenture.

     SECTION 4.06.  MAINTENANCE OF OFFICE OR AGENCY.  The Company will 
maintain in the Borough of Manhattan, The City of New York, an office or 
agency of the Trustee, Registrar and Paying Agent where Securities may be 
presented or surrendered for payment, where Securities may be surrendered for 
registration of transfer, exchange, purchase or redemption, and where notices 
and demands to or upon the Company in respect of the Securities and this 
Indenture may be served.  Unless otherwise provided pursuant to Section 2.01, 
the office or agency of the Trustee in the Borough of Manhattan, New York, 
New York, shall initially be such office or agency for all of the aforesaid 
purposes.  The Company shall give prompt written notice to the Trustee of the 
location, and of any change in the location, of any such office or agency 
(other than a change in the location of the office of the Trustee).  If at 
any time the Company shall fail to maintain any such required office or 
agency or shall fail to furnish the Trustee with the address thereof, such 
presentations, surrenders, notices and demands may be made or served at the 
address of the Trustee set forth in Section 10.11.

     SECTION 4.07.  FURTHER ASSURANCES.  From time to time whenever 
reasonably requested by the Trustee, the Company will make, execute and 
deliver, or cause to be made, executed or delivered, any and all such further 
and other instruments and assurances as may be reasonably necessary or proper 
to carry out the intention of or to facilitate the performance of the terms 
of this Indenture or to secure the rights and remedies of the Holders of 
Securities of any series provided for in this Indenture, including, but not 
limited to, furnishing all necessary information to the Trustee in connection 
with calculations and tax reporting relating to any Original Issue Discount 
Securities that may be issued by the Company hereunder.

     SECTION 5.01.  WHEN COMPANY MAY MERGE, ETC.  The Company shall not 
consolidate or merge into, or sell, assign, transfer or lease all or 
substantially all of its assets to, any person unless:

          (1)  the person is a corporation organized and existing under the

          (3)  immediately after the transaction no Default shall exist; and

          (4)  an Officers' Certificate and Opinion of Counsel have been 
     delivered to the Trustee to the effect that the conditions set forth in 
     the preceding clauses (1) through (3) above have been met.

     The corporation formed by or resulting from any such consolidation or 
merger, or which shall have received all or substantially all of such assets, 
shall succeed to and be substituted for the Company with the same effect as 
if it had been named herein as a party hereto, and thereafter, except in the 
case of a lease of all or substantially all of such assets, the predecessor 
corporation shall be relieved of all obligations and covenants under this 
Indenture and the Securities.

                                 ARTICLE 6

                          DEFAULTS AND REMEDIES

     SECTION 6.01.  EVENTS OF DEFAULT.  An "Event of Default" with respect to 
Securities of any series occurs if:

          (1)  the Company defaults in the payment of interest on any Security
     of such series when the same becomes due and payable, which Default 
     continues for a period of 30 days;


                                   -25-




          (2)  the Company defaults in the payment of the Principal of any 
     Security of such series when the same becomes due and payable at Maturity,
     upon redemption or otherwise;

          (3)  the Company fails to comply with any of its other agreements 
     with respect to Securities of such series or this Indenture (other than a
     covenant included in this Indenture solely for the benefit of any series 
     of Securities other than such series or a covenant which has not been 
     breached with respect to such series), which Default continues for a 
     period of 90 days after notice of such Default is given to the Company by 
     the Trustee or the Holders of at least 25% in principal amount of the
     Securities of such series;

          (4)  there occurs a default under any bond, indenture, note or other
     evidence of indebtedness for money borrowed by the Company or any 
     Restricted Subsidiary (including a default with respect to Securities of 
     any series other than such series) or under any mortgage, indenture or 
     instrument under which there may be issued or by which there may be 
     secured or evidenced any indebtedness for money borrowed by the Company or
     any Restricted Subsidiary (including this Indenture) with a principal 
     amount then outstanding in excess of $25,000,000, whether such indebtedness
     exists now or shall hereafter be created, which default shall constitute a
     failure to pay any portion of the principal of such indebtedness when due
     and payable after the expiration of any applicable grace period with
     respect thereto or results in such indebtedness becoming or being declared
     due and payable prior to the date on which it would otherwise have become 
     due and payable, without such indebtedness having been discharged, or such
     acceleration having been rescinded or annulled;

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

               (a)  commences a voluntary case;

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

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

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

                                   -26-



          (6)  a court of competent jurisdiction enters an order or decree under
     any Bankruptcy Law that:
   
               (a)  is for relief against the Company or any Material Subsidiary
          in an involuntary case;

               (b)  appoints a Custodian of the Company or any Material
          Subsidiary or for all or substantially all of the property of the 
          Company or such Material Subsidiary, or

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

          (7)  there occurs any other Event of Default with respect to the 
     Securities of such series specified in the terms of such series.

The term "Bankruptcy Law" means Title 11, U.S. Code or any similar federal or 
state law for the relief of debtors.  The term "Custodian" means any 
receiver, trustee, assignee, liquidator or similar official under any 
Bankruptcy Law.

     SECTION 6.02.  ACCELERATION.  If an Event of Default with respect to the 
Securities of any series occurs and is continuing, the Trustee by notice to 
the Company, or the Holders of at least 25% in principal amount of the 
Securities of that series by notice to the Company and the Trustee, may 
declare the principal (or, if the Securities of that series are Original 
Issue Discount Securities, such portion of the principal amount as may be 
specified in the terms of that series) of and accrued interest on all the 
Securities of that series to be due and payable immediately.  Upon such 
declaration, the principal (or specified amount) of and accrued interest on 
all the Securities of that series shall be due and payable immediately. The 
Holders of a majority in principal amount of the Securities of that series by 
notice to the Trustee and the Company may rescind an acceleration and its 
consequences if the rescission would not conflict with any judgment or decree 
and if all existing Events of Default with respect to the Securities of that 
series have been cured or waived except nonpayment of principal or interest 
that has become due solely because of the acceleration.

     SECTION 6.03.  OTHER REMEDIES.  If an Event of Default with respect to 
the Securities of any series occurs and is continuing, the Trustee may pursue 
any available remedy to collect the payment of principal of or interest on 
the Securities of that series or to enforce the performance of any provision 
of the Securities of that series or this Indenture.

                                   -27-



     The Trustee may maintain a proceeding even if it does not possess any of 
the Securities or does not produce any of them in the proceeding.  A delay or 
omission by the Trustee or any Securityholder in exercising any right or 
remedy upon an Event of Default shall not impair the right or remedy or 
constitute a waiver of or acquiescence in the Event of Default.  All remedies 
are cumulative to the extent permitted by law.

     SECTION 6.04.  WAIVER OF PAST DEFAULTS.  The Holders of a majority in 
outstanding principal amount of the Securities of any series by notice to the 
Trustee may waive an existing Default with respect to that series and its 
consequences, except a Default in the payment of the principal of or interest 
on any Security of that series.

     SECTION 6.05.  CONTROL BY MAJORITY.  The Holders of a majority in 
aggregate outstanding principal amount of the Securities of all series 
affected (voting as one class) may direct the time, method and place of 
conducting any proceeding for any remedy available to the Trustee or 
exercising any trust or power conferred on it with respect to the Securities 
of such series.  However, the Trustee may refuse to follow any direction that 
conflicts with law or this Indenture, is unduly prejudicial to the rights of 
another Securityholder of such series or any other series, or would involve 
the Trustee in personal liability.

     SECTION 6.06.  LIMITATION ON SUITS.  A Holder of Securities of any 
series may pursue a remedy with respect to this Indenture or the Securities 
only if:

          (1)  the Holder gives to the Trustee written notice of a continuing
     Event of Default with respect to Securities of that series;

          (2)  the Holders of a majority in principal amount of the Securities
     of that series make a written request to the Trustee to pursue the remedy;

          (3)  such Holder or Holders offer to the Trustee indemnity 
     satisfactory to the Trustee against any loss, liability or expense;

          (4)  the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer of indemnity; and

          (5)  during such period, the Holders of a majority in aggregate
     outstanding principal amount of the Securities of that series do not give
     the Trustee a direction inconsistent with the request;

                                   -28-




provided, however, that it is understood and intended, and is expressly 
covenanted by each Holder of every Security of a series with every other 
Holder and the Trustee, that no Holders of such series of Securities shall 
have any right in any manner whatsoever by virtue or by availing of any 
provision of this Indenture to affect, disturb or prejudice the rights of the 
Holders of any other series of Securities, 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.


     SECTION 6.07.  RIGHTS OF HOLDERS TO RECEIVE PAYMENT.  Notwithstanding 
any other provision of this Indenture, the right of any Holder of a Security 
to receive payment of Principal of and interest on the Security, on or after 
the respective due dates expressed in the Security, or to bring suit for the 
enforcement of any such payment on or after such respective dates, shall not 
be impaired or affected without the consent of the Holder.


     SECTION 6.08.  COLLECTION SUIT BY TRUSTEE.  If an Event of Default 
specified in Section 6.01(1) or (2) with respect to Securities occurs and is 
continuing, the Trustee may recover judgment in its own name and as trustee 
of an express trust against the Company for the whole amount of principal 
(or, if the Securities of that series are Original Issue Discount Securities, 
such portion of the principal amount as may be specified in the terms of that 
series) and interest remaining unpaid with respect to the Securities as to 
which an Event of Default has occurred.

     SECTION 6.09.  TRUSTEE MAY FILE PROOFS OF CLAIM.  The Trustee may file 
such proofs of claim and other papers or documents as may be necessary or 
advisable in order to have the claims of the Trustee and the Securityholders 
allowed in any judicial proceedings relative to the Company, its creditors or 
its property.

     SECTION 6.10.  PRIORITIES.  If the Trustee collects any money pursuant 
to this Article, it shall pay out the money in the following order:

          FIRST:  to the Trustee for amounts due under Section 7.07;


          SECOND:  to Holders of Securities in respect of which or for 
     the benefit of which such money has been collected, for amounts due and 
     unpaid on such Securities for Principal (or, if such Securities are 
     Original Issue Discount Securities, such portion of the principal 
     amount as may be specified in the terms of that series) and interest, 
     ratably, without preference or priority of any kind, according to the 
     amounts due and payable on such Securities for principal and interest, 
     respectively; and



                                     -29-



   
          THIRD:  to the Company.
   
     The Trustee may fix a record date and payment date for any payment to such
Securityholders.
   
     SECTION 6.11.  UNDERTAKING FOR COSTS.  In any suit for the enforcement 
of any right or remedy under this Indenture or in any suit against the 
Trustee for any action taken or omitted by it as Trustee, a court in its 
discretion may require the filing by any party litigant in the suit of an 
undertaking to pay the costs of the suit, and the court in its discretion may 
assess reasonable costs, including reasonable attorneys' fees, against any 
party litigant in the suit, having due regard to the merits and good faith of 
the claims or defenses made by the party litigant.  This Section does not 
apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, 
or a suit by Holders of more than 10% in principal amount of the Securities 
of any series.

                                   ARTICLE 7

                                    TRUSTEE

     SECTION 7.01.  DUTIES OF TRUSTEE.

     (a)  If an Event of Default has occurred and is continuing, the Trustee 
shall exercise 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 prudent man 
would exercise or use under the circumstances in the conduct of his own 
affairs.

     (b)  Except during the continuance of an Event of Default:

          (1)  the Trustee need perform only those duties that are specifically
     set forth in this Indenture and no others; and

          (2)  in the absence of bad faith on its part, the Trustee may 
     conclusively rely, as to the truth of the statements and the 
     correctness of the opinions expressed therein, upon certificates or 
     opinions furnished to the Trustee and conforming to the requirements of 
     this Indenture.  However, the Trustee shall examine the certificates 
     and opinions required by the terms of this Indenture to determine 
     whether or not they conform to the requirements of this Indenture but 
     need not confirm the correctness of all mathematical computations or 
     other facts or matters stated therein.


                                     -30-



     (c)  The Trustee may not be relieved from liability for its own negligent 
action, its own negligent failure to act, or its own willful misconduct, except
that:

          (1)  this paragraph does not limit the effect of paragraph (b) of this
     Section;
   
          (2)  the Trustee shall not be liable for any error of judgment made in
     good faith by a Trust Officer, unless it is proved that the Trustee was
     negligent in ascertaining the pertinent facts; and

          (3)  the Trustee shall not be liable with respect to any 
     action it takes or omits to take in good faith in accordance with a 
     direction received by it pursuant to Section 6.05 or any other 
     direction permitted by this Indenture.
   
     (d)  Every provision of this Indenture that in any way relates to the 
Trustee is subject to paragraphs (a), (b) and (c) of this Section.

     (e)  The Trustee may refuse to perform any duty or exercise any right or 
power, and no provision of this Indenture shall require the Trustee to expend 
or risk its own funds or otherwise incur financial liability, unless it 
receives indemnity satisfactory to it against any loss, liability or expense.

     (f)  The Trustee shall not be liable for interest on any money received 
by it except as the Trustee may agree with the Company.  Money held in trust 
by the Trustee need not be segregated from other funds except to the extent 
required by law.

     SECTION 7.02.  RIGHTS OF TRUSTEE.

     (a)  The Trustee may rely on any document believed by it to be genuine 
and to have been signed or presented by the proper person.  The Trustee need 
not investigate any fact or matter stated in the document.

     (b)  Before the Trustee acts or refrains from acting, it may require an 
Officers' Certificate or an Opinion of Counsel, or both.  The Trustee shall 
not be liable for any action it takes or omits to take in good faith in 
reliance on such Officers' Certificate or Opinion of Counsel.

     (c)  The Trustee may act through agents and shall not be responsible for 
the misconduct or negligence of any agent appointed with due care.

                                     -31-



     (d)  The Trustee shall not be liable for any action it takes or omits to 
take in good faith which it believes to be authorized or within its rights or 
powers.

     (e)  The Trustee may consult with counsel, and the advice or opinion of 
counsel with respect to legal matters relating to this Indenture and the 
Securities shall be full and complete authorization and protection from 
liability in respect to any action taken, omitted or suffered by it hereunder 
in good faith and in accordance with the advice or opinion of such counsel.

     (f)  The Trustee shall be under no obligation to exercise any of the 
rights or powers vested in it by this Indenture at the request or direction 
of any of the Holders pursuant to this Indenture, unless such Holders shall 
have offered to the Trustee reasonable security or indemnity against the 
costs, expenses and liabilities which might be incurred by it in compliance 
with such request or direction.

     (g)  For all purposes under this Indenture, the Trustee shall not be 
deemed to have notice or knowledge of any Event of Default (other than under 
Section 6.01(1) and (2)) unless a Trust Officer knows of such Event of 
Default or unless written notice of any Event of Default (other than under 
Section 6.01(1) or (2)) is received by the Trustee at its address specified 
in Section 10.11 hereof and such notice references the Securities generally, 
the Company or this Indenture.

     SECTION 7.03.  INDIVIDUAL RIGHTS OF TRUSTEE.  The Trustee in its 
individual or any other capacity may become the owner or pledgee of 
Securities of any series and may otherwise deal with the Company or an 
Affiliate with the same rights it would have if it were not Trustee.  Any 
Agent may do the same with like rights.  However, the Trustee is subject to 
Sections 7.10 and 7.11.

     SECTION 7.04.  TRUSTEE'S DISCLAIMER.  The Trustee makes no 
representation as to the validity or adequacy of this Indenture or the 
Securities, it shall not be accountable for the Company's use of the proceeds 
from the Securities, and it shall not be responsible for any statement in the 
Securities other than its authentication.

     SECTION 7.05.  NOTICE OF DEFAULTS.  If a Default in respect of the 
Securities of any series occurs and is continuing and if it is known to the 
Trustee, the Trustee shall mail to the Holders of the Securities of that 
series a notice of the Default within 90 days after it occurs. Except in the 
case of a Default in payment of the principal or interest on any Security, or 
in the payment of any sinking fund or purchase fund installment, the Trustee 
may withhold the notice if and so long as a committee of its Trust Officers 
in good faith determines that withholding the notice is in the interests of 
the Holders of the Securities of that series.


                                     -32-



     SECTION 7.06.  REPORTS BY TRUSTEE TO HOLDERS.  If required by TIA 
Section 313(a), within 60 days after the reporting date stated in this Section 
7.06, the Trustee shall mail to Securityholders of each series a brief report 
dated as of such reporting date that complies with TIA Section 313(a).  The 
Trustee shall also comply with TIA Section 313(b).  For purposes of this 
Section 7.06, the reporting date shall be May 15 of each year.  The first 
reporting date will be the first May 15 following the issuance of the first 
series of Securities hereunder.

     A copy of each report at the time of its mailing to Securityholders of 
each series shall be filed with the SEC and each stock exchange on which the 
Securities of each series are listed.  The Company will notify the Trustee of 
the listing of Securities of any series on a stock exchange.

     SECTION 7.07.  COMPENSATION AND INDEMNITY.  The Company shall pay to the 
Trustee from time to time reasonable compensation including compensation for 
extraordinary services related to default administration for its services.  
The Trustee's compensation shall not be limited by any law on compensation of 
a trustee of an express trust.  The Company shall reimburse the Trustee upon 
request for all reasonable expenses incurred by it.  Such expenses shall 
include the reasonable compensation and expenses of the Trustee's agents and 
counsel.

     The Company shall indemnify the Trustee against any loss or liability 
incurred by it arising out of or in connection with the acceptance or 
administration of this Indenture, including the costs and expenses of 
defending itself against any claims or liability in connection with the 
exercise or performance of any of its powers or duties hereunder.  The 
Trustee shall notify the Company promptly of any claim for which it may seek 
indemnity. The Company shall defend the claim and the Trustee shall cooperate 
in the defense.  The Trustee may have separate counsel and the Company shall 
pay the reasonable fees and expenses of such counsel.  The Company need not 
pay for any settlement made without its consent.

     The Company need not reimburse any expense or indemnify against any loss 
or liability incurred by the Trustee if the acts or omissions of the Trustee, 
if any, relating to such loss or liability, breached any standard of care 
applicable to or imposed on the Trustee for such acts or omissions.

     To secure the Company's payment obligations in this Section, the Trustee 
shall have a lien prior to the Securities on all money or property held or 
collected by the Trustee, except that held in trust to pay principal and 
interest on particular Securities.


                                     -33-



     When the Trustee incurs expenses or renders services after an Event of 
Default specified in Section 6.01(5) or (6) occurs, the expenses and the 
compensation for the services are intended to constitute expenses of 
administration under any Bankruptcy Law.

     SECTION 7.08.  REPLACEMENT OF TRUSTEE.  A resignation or removal of the 
Trustee and appointment of a successor Trustee shall become effective only 
upon the successor Trustee's acceptance of appointment as provided in this 
Section.

     The Trustee may resign at any time with respect to the Securities of one 
or more series by so notifying the Company.  The Holders of a majority in 
principal amount of the then-outstanding Securities of any series may remove 
the Trustee with respect to such series by so notifying the Trustee and the 
Company.  The Company may remove the Trustee with respect to the Securities 
of one or more series if:

          (1)  the Trustee fails to comply with Section 7.10;

          (2)  the Trustee is adjudged a bankrupt or an insolvent;

          (3)  a receiver or public officer takes charge of the Trustee or its
               property; or

          (4)  the Trustee becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the 
office of Trustee for any reason, with respect to the Securities of any one 
or more series, the Company shall promptly appoint a successor Trustee or 
Trustees with respect to the Securities of that or those series (it being 
understood that any such successor Trustee may be appointed with respect to 
the Securities of one or more or all of such series and that at any time 
there shall be only one Trustee with respect to the Securities of any 
particular series) and shall comply with the applicable requirements of 
Section 7.10. Within one year after the successor Trustee takes office, the 
Holders of a majority in principal amount of the then-outstanding Securities 
of each series may appoint a successor Trustee with respect to the Securities 
of their respective series to replace the successor Trustee for the 
Securities of such series appointed by the Company.

     If a successor Trustee with respect to the Securities of any series does 
not take office within 60 days after the retiring Trustee with respect to the 
Securities of that series resigns or is removed, the retiring Trustee, the 
Company or the Holders of at least 10% in principal amount of the 
then-outstanding Securities of that series may petition any court of 
competent jurisdiction for the appointment of a successor Trustee with 
respect to the Securities of that series.

                                     -34-



     If the Trustee fails to comply with Section 7.10, with respect to the 
Securities of one or more series, any Holder of Securities of such series may 
petition any court of competent jurisdiction for the removal of the Trustee 
with respect to the Securities of that series and the appointment of a 
successor Trustee with respect to the Securities of that series.

     In the case of the appointment of a successor Trustee with respect to 
all Securities, the successor Trustee shall deliver a written acceptance of 
its appointment to the retiring Trustee and to the Company.  Thereupon the 
resignation or removal of the retiring Trustee shall become effective, and 
the successor Trustee shall have all the rights, powers and duties of the 
Trustee under this Indenture.  The successor Trustee shall mail a notice of 
its succession to all Securityholders.  The retiring Trustee shall promptly 
transfer all property held by it as Trustee to the successor Trustee, subject 
to the lien provided for in Section 7.07.  Notwithstanding the replacement of 
the Trustee pursuant to this Section 7.08, the Company's obligations under 
Section 7.07 hereof shall continue for the benefit of the retiring Trustee 
with respect to expenses and liabilities incurred by it prior to such 
replacement.

     In case of the appointment of a successor Trustee with respect to the 
Securities of one or more (but not all) series, the Company, the retiring 
Trustee and each successor Trustee with respect to the Securities of one or 
more series shall execute and deliver an indenture supplemental hereto 
wherein each successor Trustee shall accept such appointment and which (i) 
shall contain such provisions as shall be necessary or desirable to transfer 
and confirm to, and to vest in, each successor Trustee all the rights, 
powers, trusts and duties of the retiring Trustee with respect to the 
Securities of that or those series to which the appointment of such successor 
Trustee relates, (ii) if the retiring Trustee is not retiring with respect to 
all series of Securities, shall contain such provisions as shall be deemed 
necessary or desirable to confirm that all the rights, powers, trusts and 
duties of the retiring Trustee, with respect to the Securities of that or 
those series as to which the retiring Trustee is not retiring, shall continue 
to be vested in the retiring Trustee and (iii) shall add to or change any of 
the provisions of this Indenture as shall be necessary to provide for or 
facilitate the administration of the trusts hereunder by more than one 
Trustee, it being understood that nothing herein or in such supplemental 
indenture shall constitute such Trustees co-trustees of the same trust and 
that each such Trustee shall be trustee of a trust or trusts hereunder 
separate and apart from any trust or trusts hereunder administered by any 
other such Trustee; and upon the execution and delivery of such supplemental 
indenture the resignation or removal of the retiring Trustee shall become 
effective to the extent provided therein and the successor Trustee shall have 
all the rights, powers and duties of the retiring Trustee with respect to the 
Securities of that or those series to which the appointment of such successor 
Trustee relates.  The successor Trustee shall mail a notice of its succession 
to the Holders of all Securities of that or those series to which the 
appointment of such successor Trustee relates.  The retiring Trustee shall 
promptly transfer all property held by it with respect to the Securities of 
that or those series to which the 


                                     -35-



appointment of such successor Trustee relates, subject to the lien provided 
for in Section 7.07. Notwithstanding the replacement of the Trustee pursuant 
to this Section 7.08, the Company's obligations under Section 7.07 hereof 
shall continue for the benefit of the retiring Trustee with respect to 
expenses and liabilities incurred by it prior to such replacement.  No 
successor Trustee with respect to Securities of any series shall accept 
appointment as provided in this Section 7.08 unless at the time of such 
acceptance such successor Trustee shall be qualified and eligible under the 
provisions of Section 7.10.

     SECTION 7.09.  SUCCESSOR TRUSTEE BY MERGER, ETC.  If the Trustee 
consolidates, merges or converts into, or transfers all or substantially all 
of its corporate trust business to, another corporation, the successor 
corporation without any further act shall be the successor Trustee.

     SECTION 7.10.  ELIGIBILITY, DISQUALIFICATION.  This Indenture shall 
always have a Trustee with respect to the Securities of each series 
which satisfies the requirements of TIA Section 310(a)(1) and (5).  The

HOWEVER, that there shall be excluded from the operation of TIA

                                  ARTICLE 8

                     DISCHARGE OF INDENTURE AND SECURITIES


     SECTION 8.01.  SATISFACTION AND DISCHARGE OF INDENTURE.  If at any 
time (a) the Company shall have paid or caused to be paid the Principal of 
and interest on all the Securities of any series outstanding hereunder, as 
and when the same shall have become due and payable, or (b) the Company shall 
have delivered to the Trustee for cancellation all Securities of any series 
theretofore authenticated (other than any Securities of such series which 
shall have been destroyed, lost or stolen and which shall have been replaced 
as provided in Section 2.07 or paid), and if, in any such case, the Company 
shall also pay or 

                                      -36-




cause to be paid all other sums payable hereunder by the Company with respect 
to Securities of such series, then this Indenture shall cease to be of 
further effect with respect to Securities of such series (except as to (i) 
rights of registration of transfer and exchange, and the Company's right of 
optional redemption, if any, (ii) substitution of apparently mutilated, 
defaced, destroyed, lost or stolen Securities, (iii) rights of the Holders to 
receive payments of Principal thereof and interest thereon from the trust 
fund established pursuant to Section 8.02, and remaining rights of the 
Holders to receive mandatory sinking fund payments, if any, from the trust 
fund established pursuant to Section 8.02, (iv) the rights, obligations and 
immunities of the Trustee hereunder, (v) the rights of the Securityholders of 
such series as beneficiaries hereof with respect to the property so deposited 
with the Trustee payable to all or any of them, (vi) all other obligations of 
the Company in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 7.07, 7.08 and 8.06 and 
(vii) the Company's rights pursuant to Sections 7.08, 8.05 and 8.06), and the 
Trustee, on demand of the Company accompanied by an Officers' Certificate and 
an Opinion of Counsel and at the cost and expense of the Company, shall 
execute proper instruments acknowledging such satisfaction of and discharging 
this Indenture with respect to Securities of such series.  The Company 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 of such series.

     SECTION 8.02.  DEFEASANCE.  For purposes of Section 8.01, the 
Company shall be deemed to have paid the Principal of and interest on 
Securities of any series outstanding hereunder as and when the same 
shall have become due and payable, if the Company shall have irrevocably 
deposited or caused to be deposited in trust with the Trustee funds in 
cash and/or U.S. Government Obligations sufficient without reinvestment 
thereof, in the opinion of a nationally recognized firm of independent 
public accountants expressed in a written certification thereof 
delivered to the Trustee, to provide for timely payment of Principal of 
and interest on the Securities of such series to Stated Maturity or 
redemption, as the case may be, not theretofore delivered to the Trustee 
for cancellation; provided, however, that (i) in order to have money 
available on a payment date to pay Principal or interest on the 
Securities of such series, the U.S. Government Obligations shall be 
payable as to principal and interest on or before such payment date in 
such amounts as will provide the necessary money; and (ii) the Company 
shall obtain an Opinion of Counsel (which may be based on a ruling from, 
or published by, the Internal Revenue Service) to the effect that 
Holders of the Securities of that series 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 and 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 provided, further, however, that notwithstanding the 
foregoing, with respect to any series of Securities which shall at the 
time be listed for trading on The New York Stock Exchange, there shall 
be no deposit of funds in cash and/or in U.S. Government Obligations 
with the 



                                      -37-




Trustee to pay the Principal amount, the redemption price or 
any installment of interest in order to discharge the Company's 
obligation in respect of any such payment if at such time the rules of 
The New York Stock Exchange prohibit such deposit with the Trustee.


     SECTION 8.03.  SATISFACTION AND DISCHARGE OF SECURITIES.  Securities of 
a series shall be deemed to have been paid in full as between the Company and 
the respective Holders (and future Holders) of Securities of such series upon 
the satisfaction and discharge of the Indenture with respect to Securities of 
such series pursuant to Section 8.01, except that in the case of such 
satisfaction and discharge as a result of compliance with Section 8.02, the 
Securities of such series shall be deemed to have been paid in full as 
between the Company and the respective Holders (and future Holders) of 
Securities of such series only if the deposit in trust with the Trustee by 
the Company of the funds in cash and/or U.S. Government Obligations as 
provided in Section 8.02 is not subsequently deemed a preference under the 
United States Bankruptcy Code as then in effect.

     SECTION 8.04.  APPLICATION BY TRUSTEE OF MONEY OR U.S. GOVERNMENT 
OBLIGATIONS. Subject to Section 8.06, all money or U.S. Government 
Obligations deposited with the Trustee pursuant to Section 8.02 shall be 
held in trust and applied by it to the payment, either directly or 
through the Paying Agent to the Holders of the particular Securities of 
such series for the payment or redemption of which such money or U.S. 
Government Obligations shall have been deposited with the Trustee, of 
all sums due and to become due thereon for principal and interest but 
money so held in trust need not be segregated from other funds except to 
the extent required by law.

     SECTION 8.05.  REPAYMENT OF MONEY OR U.S. GOVERNMENT OBLIGATIONS BY 
PAYING AGENT.  In connection with the satisfaction and discharge of this 
Indenture with respect to Securities of any series, all money or U.S. 
Government Obligations then held by the Paying Agent under the 
provisions of this Indenture with respect to such series of Securities 
shall, upon demand of the Company, be paid or delivered to the Trustee 
and thereupon the Paying Agent shall be released from all further 
liability with respect to such money or U.S. Government Obligations.

     SECTION 8.06.  RETURN OF MONEY, SECURITIES OR U.S. GOVERNMENT 
OBLIGATIONS. The Trustee and the Paying Agent shall promptly pay to the 
Company upon request any money, U.S. Government Obligations or 
Securities that, in the opinion of a nationally recognized firm of 
independent public accountants expressed in a written certification 
thereof delivered to the Trustee, are in excess of the amount required 
under Section 8.02. Any money or U.S. Government Obligations deposited 
with or paid to the Trustee or the Paying Agent for the payment of the 
Principal of, or interest on any Security of any series and not applied 
but remaining unclaimed for two years after the date upon which such 
Principal or interest shall become due and payable, shall, upon the 
request of the Company 


                                      -38-




and unless otherwise required by mandatory provisions of applicable 
escheat or abandoned or unclaimed property laws, be repaid or delivered 
to the Company by the Trustee for such series or by the Paying Agent, 
and the Holder of the Security of such series shall, unless otherwise 
required by mandatory provisions of applicable escheat or abandoned or 
unclaimed property laws, thereafter look only to the Company for any 
payment which such Holder may be entitled to collect, and all liability 
of the Trustee or the Paying Agent with respect to such money or U.S. 
Government Obligations shall thereupon cease.

     SECTION 8.07.  REINSTATEMENT.  If the Trustee is unable to apply 
any money or U.S. Government Obligations in accordance with Section 8.02 
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 Company's obligations under 
this Indenture and the Securities shall be revived and reinstated as 
though no deposit had occurred pursuant to Section 8.02 until such time 
as the Trustee is permitted to apply all such money or U.S. Government 
Obligations in accordance with Section 8.02.

                                  ARTICLE 9

                                  AMENDMENTS

     SECTION 9.01.  WITHOUT CONSENT OF HOLDERS.  The Company and the 
Trustee may amend this Indenture or the Securities without the consent 
of any Securityholder:

          (1)  to cure any ambiguity, defect or inconsistency or to make such 
     provisions with respect to matters or questions arising under this 
     Indenture as may be necessary or desirable and not inconsistent with 
     this Indenture or with any indenture supplemental hereto or any Board 
     Resolution establishing any series of Securities, provided that such 
     amendment does not adversely affect the rights of Securityholders;

          (2)  to comply with Section 5.01;

          (3)  to add additional covenants;

          (4)  to establish the form or forms or terms with respect to 
     Securities of any additional series as permitted by Section 2.01;

          (5)  to evidence and provide for the acceptance of appointment of 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 

                                      -39-



     or facilitate the administration of the trusts hereunder by more than 
     one Trustee, pursuant to the requirements of Section 7.08; or

          (6)  to provide for the issuance of Securities of any series with 
     interest coupons; and 

          (7)  to provide for the exchange of Global Securities for 
     Securities issued hereunder in definitive form and to make all 
     appropriate changes for such purpose.

     SECTION 9.02.  WITH CONSENT OF HOLDERS.  The Company and the 
Trustee may amend this Indenture in a manner affecting the Securities of 
any series, or may amend the Securities of such series, with the written 
consent of the Holders of at least 66-2/3% in principal amount of the 
then-outstanding Securities of such series.  However, without the 
consent of each Securityholder affected, an amendment under this Section 
may not:

          (1)  reduce the percentage in principal amount of Securities whose 
     Holders must consent to an amendment;
     
          (2)  reduce the rate of or change the time for payment of interest 
     on any Security;
     
          (3)  reduce the Principal of (or, in the case of Original Issue 
     Discount Securities, the amount of such Securities that would be due and 
     payable upon acceleration of the Maturity thereof pursuant to Section 
     6.02), change the Stated Maturity of or reduce the amount payable on 
     redemption of or otherwise alter the requirements with respect to the 
     mandatory redemption of any Security;
     
          (4)  make any Security payable in money other than that stated in 
     the Security; or
     
          (5)  make any change in Section 6.04 or 6.07 or this Section 9.02. 
     
     After an amendment under this Section becomes effective, the Company 
shall mail to Securityholders a notice briefly describing the amendment.

     SECTION 9.03.  COMPLIANCE WITH TRUST INDENTURE ACT.  Every amendment to 
this Indenture or the Securities shall be set forth in a supplemental 
indenture that complies with the TIA as then in effect.

     SECTION 9.04.  EFFECT OF CONSENTS.  A consent to an amendment or waiver 
by a Holder of a Security is effective upon delivery to the Trustee and is a 
continuing consent by 


                                      -40-



the Holder and every subsequent Holder of a Security or portion of a 
Security that evidences the same debt as the consenting Holder's 
Security, even if notation of the consent is not made on any Security; 
however, any such Holder or subsequent Holder may revoke the consent as 
to his Security or portion of a Security if the Trustee receives the 
notice of revocation before the date the amendment or waiver becomes 
effective.  An amendment or waiver becomes effective in accordance with 
its terms and thereafter binds every Securityholder, except to the 
extent each Securityholder affected must consent and such Securityholder 
did not do so.

     SECTION 9.05.  NOTATION ON OR EXCHANGE OF SECURITIES.  The Trustee 
may place an appropriate notation about an amendment or waiver on any 
Security thereafter authenticated.  The Company in exchange for all 
Securities may issue and the Trustee shall authenticate new Securities 
that reflect the amendment or waiver.

     SECTION 9.06.  TRUSTEE PROTECTED.  The Trustee need not sign any 
supplemental indenture that adversely affects its rights.  In signing such 
amendment the Trustee shall be entitled to receive indemnity reasonably 
satisfactory to it and to receive, and (subject to Section 7.01) shall be 
fully protected in relying upon, an Officers' Certificate and an Opinion of 
Counsel stating that such amendment is authorized or permitted by this 
Indenture and complies with the provisions hereof (including Section 9.03).

                                  ARTICLE 10

                                MISCELLANEOUS

     SECTION 10.01.  TRUST INDENTURE ACT CONTROLS.  If any provision of this 
Indenture limits, qualifies, or conflicts with another provision which is 
required to be included in this Indenture by the TIA, the required provision 
shall control.

     SECTION 10.02.  NOTICES.  Any notice or communication by the Company or 
the Trustee to the other shall be in writing and shall be delivered in person 
or mailed by first-class mail or overnight air courier guaranteeing next-day 
delivery to the other's address stated in Section 10.11; provided, however, 
that any such notice shall be deemed duly given when such notice is received 
by the Company or the Trustee, as the case may be. The Company or the Trustee 
by notice to the other may designate additional or different addresses for 
subsequent notices or communications.


                                      -41-



     Any notice or communication to a Securityholder shall be mailed by 
first-class mail or overnight air courier guaranteeing next-day delivery to 
his address shown on the Security Register.  Failure to mail a notice or 
communication to a Securityholder or any defect in a notice shall not affect 
the sufficiency thereof with respect to any other Securityholders.

     Except as provided above, if a notice or communication is mailed in the 
manner and within the time prescribed above, it shall be deemed duly given, 
whether or not the addressee receives it.

     If the Company mails a notice or communication to Securityholders, it 
shall mail a copy to the Trustee and each Agent at the same time.

     SECTION 10.03.  COMMUNICATIONS BY HOLDERS WITH OTHER HOLDERS. 
Securityholders may communicate pursuant to TIA Section 312(b) with 
other Securityholders with respect to their rights under this Indenture 
or the Securities.  The Company, the Trustee, the Registrar and anyone 
else affected shall be entitled to the protection of TIA Section 312(c).

     SECTION 10.04.  CERTIFICATE AND OPINION AS TO CONDITIONS PRECEDENT.  
Upon any request or application by the Company to the Trustee to take any 
action under this Indenture, the Company shall furnish to the Trustee:

          (1)  an Officers' Certificate stating that, in the opinion of the 
     signers, all conditions precedent, if any, provided for in this 
     Indenture relating to the proposed action have been complied with; and
     
          (2)  an Opinion of Counsel stating that, in the opinion of such 
     counsel, all such conditions precedent have been complied with.

     SECTION 10.05.  STATEMENTS REQUIRED IN CERTIFICATE OR OPINION.  Each 
certificate or opinion with respect to compliance with a condition or 
covenant provided for in this Indenture shall include:

          (1)  a statement that each person making such certificate or 
     opinion has read such covenant or condition;
     
          (2)  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;
     
          (3)  a statement that, in the opinion of each such person, he has 
     made such examination or investigation as is necessary to enable him to 
     express an 


                                      -42-



     informed opinion as to whether or not such covenant or condition 
     has been complied with; and
     
          (4)  a statement as to whether, in the opinion of each such person, 
     such condition or covenant has been complied with.

     Any Officers' Certificate may be based, insofar as it relates to 
legal matters, upon an Opinion of Counsel, unless such Officer knows 
that the opinion with respect to the matters upon which his certificate 
may be based as aforesaid are erroneous, or in the exercise of 
reasonable care should know that the same are erroneous.  Any Opinion of 
Counsel may be based, insofar as it relates to factual matters the 
information with respect to which is in the possession of the Company, 
upon the certificate, statement or opinion of or representations by an 
officer or officers of the Company, unless such counsel knows that the 
certificate, statement or opinion or representation 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 Officers' Certificate, statement or Opinion of Counsel may be based, 
insofar as it relates to accounting matters, upon a certificate or opinion of 
or representations by an accountant (who may be an employee of the Company), 
or firm of accountants, 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 the 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 or opinion of any 
independent firm of public accountants filed with the Trustee shall contain a 
statement that such firm is independent.

     SECTION 10.06.  RULES BY TRUSTEE AND AGENTS.  The Trustee may make 
reasonable rules for action by written consent or at a meeting of Holders of 
Securities of any series. The fact and date of the execution of a written 
consent or other writing by any such person shall be established in 
accordance with the procedures specified in such reasonable rules, and the 
ownership of Securities of any series shall be established by the Security 
Register for such series maintained by the Registrar.  The Registrar or 
Paying Agent may make reasonable rules and set reasonable requirements for 
its functions.

     SECTION 10.07.  LEGAL HOLIDAYS.  A "Legal Holiday" is a Saturday, a 
Sunday or a day on which banking institutions in any place of payment are not 
required to be open. If a payment date with respect to a particular series of 
Securities is a Legal Holiday at a place of payment, payment may be made at 
that place on the next succeeding day that is not a Legal Holiday, and no 
interest shall accrue for the intervening period.



                                      -43-



     SECTION 10.08.  NO RECOURSE AGAINST OTHERS.  No person shall have any 
recourse under or upon any obligation or agreement of the Company under this 
Indenture or the Securities of any series or because of any debt evidenced by 
the Securities of any series against any stockholder, officer, employee or 
director, as such, of the Company.  By accepting a Security of any series, 
each Holder waives and releases all such liability as a part of the 
consideration for the issuance thereof. 

     SECTION 10.09.  INTEREST LIMITATION.  If any usury law now or at 
any time hereafter in force shall be applicable to this Indenture or the 
Securities of any series or any other document or instrument related 
hereto or thereto, it is the intention of the Company and the Trustee to 
conform strictly to any such usury laws and any subsequent revisions or 
repeals thereof.  In furtherance thereof, the Company and the Trustee 
stipulate and agree that none of the terms and provisions contained in 
this Indenture or the Securities of any series or any other document or 
instrument related hereto or thereto shall ever be construed to give 
rise to a contract or obligation to pay interest in excess of the 
maximum amount permitted to be contracted for, taken, reserved, charged, 
collected or received under any applicable law. 

     SECTION 10.10.  DUPLICATE ORIGINALS.  The parties may sign any number of

continue to be Holders after such record date.

that would require the application of the laws of any other jurisdiction) and

ninety-six before me personally came B. D. St. John to me known who, being by 
me duly sworn, did depose and say that he is Vice Chairman of DRESSER

above instrument; that he knows the corporate seal of said corporation; that 
the seal affixed to said instrument is such corporate seal; that it was so
