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

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

                  Section 104. Acts of Securityholders. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Securityholders or Securityholders of any
series may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Securityholders in person or by an
agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
are delivered to the Trustee, and, where it is hereby expressly required, to the
Company. If any Securities are denominated in coin or currency other than that
of the United States, then for the purposes of determining whether the Holders
of the requisite principal amount of Securities have taken any action as herein
described, the principal amount of such Securities shall be

   19
                                                                              12



deemed to be that amount of United States dollars that could be obtained for
such principal amount on the basis of the spot rate of exchange into United
States dollars for the currency in which such Securities are denominated (as
evidenced to the Trustee by an Officers' Certificate) as of the date the taking
of such action by the Holders of such requisite principal amount is evidenced to
the Trustee as provided in the immediately preceding sentence. Such instrument
or instruments (and the action embodied therein and evidenced thereby) are
herein sometimes referred to as the "Act" of the Securityholders signing such
instrument or instruments. Proof of execution of any such instrument or of a
writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved by the affidavit of a witness to such
execution or by the certificate of any notary public or other officer authorized
by law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by an officer of a corporation or a member of a partnership, on
behalf of such corporation or partnership, such certificate or affidavit shall
also constitute sufficient proof of his authority. The fact and date of the
execution of any such instrument or writing, or the authority of the person
executing the same, may also be proved in any other manner which the Trustee
deems sufficient.

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

                  (d) If the Company shall solicit from the Holders any request,
demand, authorization, direction, notice, consent, waiver or other action, the
Company may, at its option, by Board Resolution, fix in advance a record date
for the determination of Holders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other action, but the
Company shall have no obligation to do so. If such a record date is fixed, such
request, demand, authorization, direction, notice, consent, waiver or other
action may be given before or after the record date, but only the Holders of
record at the close of business on the record date shall be deemed to be Holders
for the purposes of determining whether Holders of the

   20
                                                                              13



requisite proportion of Securities Outstanding have authorized or agreed or
consented to such request, demand, authorization, direction, notice, consent,
waiver or other action, and for that purpose the Securities Outstanding shall be
computed as of the record date; provided that no such authorization, agreement
or consent by the Holders on the record date shall be deemed effective unless it
shall become effective pursuant to the provisions of this Indenture not later
than six months after the record date.

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

                  Section 105. Notices, etc., to Trustee and Company. Any
request, demand, authorization, direction, notice, consent, waiver or Act of
Securityholders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,

                  (1) the Trustee by any Securityholder or by the Company shall
         be sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with the Trustee at its Corporate Trust Office,
         or

                  (2) the Company by the Trustee or by any Securityholder shall
         be sufficient for every purpose hereunder (except as provided in
         Section 501(4) or, in the case of a request for repayment, as specified
         in the Security carrying the right to repayment) if in writing and
         mailed, first-class postage prepaid, to the Company addressed to it at
         the address of its principal office specified in the first paragraph of
         this instrument or at any other address previously furnished in writing
         to the Trustee by the Company.

                  Section 106. Notices to Securityholders; Waiver. Where this
Indenture or any Security provides for notice to Securityholders of any event,
such notice shall be sufficiently given (unless otherwise herein or in such
Security expressly provided) if in writing and mailed, first-class postage
prepaid, to each Securityholder affected by such event, at his address as it
appears in the Security

   21
                                                                              14



Register, not later than the latest date, and not earlier than the earliest
date, prescribed for the giving of such notice. In any case where notice to
Securityholders is given by mail, neither the failure to mail such notice, nor
any defect in any notice so mailed, to any particular Securityholder shall
affect the sufficiency of such notice with respect to other Securityholders.
Where this Indenture or any Security provides for notice in any manner, such
notice may be waived in writing by the Person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of
such notice. Waivers of notice by Securityholders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

                  In case, by reason of the suspension of regular mail service
as a result of a strike, work stoppage or otherwise, it shall be impractical to
mail notice of any event to any Securityholder when such notice is required to
be given pursuant to any provision of this Indenture, then any method of
notification as shall be satisfactory to the Trustee and the Company shall be
deemed to be a sufficient giving of such notice.

                  Section 107. Conflict with Trust Indenture Act. If any
provision hereof limits, qualifies or conflicts with the duties imposed by any
of Sections 310 to 317, inclusive, of the Trust Indenture Act through the
operation of Section 318(c) thereof, such imposed duties shall control.

                  Section 108. Effect of Headings and Table of Contents. The
Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

                  Section 109. Successors and Assigns. All covenants and
agreements in this Indenture by the Company shall bind its successors and
assigns, whether so expressed or not.

                  Section 110. Separability Clause. In case any provision in
this Indenture or in the Securities shall be invalid, illegal or unenforceable,
the validity, legality and enforceability of the remaining provisions shall not
in any way be affected or impaired thereby.
   22
                                                                              15



                  Section 111. Benefits of Indenture. Nothing in this Indenture
or in any Securities, express or implied, shall give to any Person, other than
the parties hereto and their successors hereunder, any Authenticating Agent or
Paying Agent, the Security Registrar and the Holders of Securities (or such of
them as may be affected thereby), any benefit or any legal or equitable right,
remedy or claim under this Indenture.

                  Section 112.  Governing Law.  This Indenture shall
be construed in accordance with and governed by the laws of
the State of New York.

                  Section 113.  Counterparts.  This instrument may
be executed in any number of counterparts, each of which so
executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same
instrument.

                  Section 114. Judgment Currency. The Company agrees, to the
fullest extent that it may effectively do so under applicable law, that (a) if
for the purpose of obtaining judgment in any court it is necessary to convert
the sum due in respect of the principal of, or premium or interest, if any, on
the Securities of any series (the "Required Currency") into a currency in which
a judgment will be rendered (the "Judgment Currency"), the rate of exchange used
shall be the rate at which in accordance with normal banking procedures the
Trustee could purchase in the City of New York the Required Currency with the
Judgment Currency on the New York Banking Day (as defined below) preceding that
on which final unappealable judgment is given and (b) its obligations under this
Indenture to make payments in the Required Currency (i) shall not be discharged
or satisfied by any tender, or any recovery pursuant to any judgment (whether or
not entered in accordance with subsection (a)), in any currency other than the
Required Currency, except to the extent that such tender or recovery shall
result in the actual receipt, by the payee, of the full amount of the Required
Currency expressed to be payable in respect of such payments, (ii) shall be
enforceable as an alternative or additional cause of action for the purpose of
recovering in the Required Currency the amount, if any, by which such actual
receipt shall fall short of the full amount of the Required Currency so
expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture. For purposes of the
foregoing, "New York Banking

                                                                              16



Day" means any day except a Saturday, Sunday or a legal holiday in the City of
New York or a day on which banking institutions in the City of New York are
authorized or required by law or executive order to close.

                                 Security Forms

                  Section 201. Forms Generally. The Securities shall have such
appropriate insertions, omissions, substitutions and other variations as are
required or permitted by this Indenture and may have such letters, numbers or
other marks of identification and such legends or endorsements placed thereon,
as may be required to comply with applicable laws or regulations or with the
rules of any securities exchange, or as may, consistently herewith, be
determined by the officers executing such Securities, as evidenced by their
execution of the Securities. Any portion of the text of any Security may be set
forth on the reverse thereof, with an appropriate reference thereto on the face
of the Security.

                  The definitive Securities shall be printed, lithographed or
engraved or produced by any combination of these methods on steel engraved
borders or may be produced in any other manner, all as determined by the
officers executing such Securities, as evidenced by their execution of such
Securities, subject, with respect to the Securities of any series, to the rules
of any securities exchange on which such Securities are listed.

                  Section 202. Forms of Securities. Each Security shall be in
one of the forms approved from time to time by or pursuant to a Board
Resolution, or established in one or more indentures supplemental hereto. Prior
to the delivery of a Security to the Trustee for authentication in any form
approved by or pursuant to a Board Resolution, the Company shall deliver to the
Trustee the Board Resolution by or pursuant to which such form of Security has
been approved, which Board Resolution shall have attached thereto a true and
correct copy of the form of Security which has been approved thereby or, if a
Board Resolution authorizes a specific officer or officers to approve a form of
Security, a certificate of such officer or officers approving the form of
Security attached thereto. Any form of Security approved by or pursuant to a
Board Resolution must be acceptable as
   24
                                                                              17



to form to the Trustee, such acceptance to be evidenced by the Trustee's
authentication of Securities in that form or a certificate signed by a
Responsible Officer of the Trustee and delivered to the Company.

                  Section 203. Form of Trustee's Certificate of Authentication.
The form of Trustee's Certificate of Authentication for any Security issued
pursuant to this Indenture shall be substantially as follows:

                     TRUSTEE'S CERTIFICATE OF AUTHENTICATION

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


                                       CITIBANK, N.A.,
                                         as Trustee,


                                         By:________________________
                                              Authorized Signatory

                  Section 204. Securities Issuable in the Form of a Global
Security. (a) If the Company shall establish pursuant to Sections 202 and 301
that the Securities of a particular 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 or its agent shall, in accordance with Section 303 and the Company
Request delivered to the Trustee or its agent thereunder, authenticate and
deliver, such Global Security or Securities, which (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 such Global
Security or Securities, or such portion thereof as the Company shall specify in
a Company Request, (ii) shall be registered in the name of the Depositary for
such Global Security or Securities or its nominee, (iii) shall be delivered by
the Trustee or its agent to the Depositary or pursuant to the Depositary's
instruction and (iv) shall bear a legend substantially to the following effect:
"Unless and until it is exchanged in whole or in part for the individual
Securities represented hereby, this Global Security may not be transferred
except as a whole by the Depositary to a nominee of the Depositary or by a
nominee of the Depositary to the Depositary or
   25
                                                                              18



another nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary."

                  (b) Notwithstanding any other provisions of this Section 204
or of Section 305, and subject to the provisions of paragraph (c) below, unless
the terms of a Global Security expressly permit such Global Security to be
exchanged in whole or in part for individual Securities, a Global Security may
be transferred, in whole but not in part and in the manner provided in Section
305, only to a nominee of the Depositary for such Global Security, or to the
Depositary, or a successor Depositary for such Global Security selected or
approved by the Company, or to a nominee of such successor Depositary.

                  (c) (i) If at any time the Depositary for a Global Security
notifies the Company that it is unwilling or unable to continue as Depositary
for such Global Security or if at any time the Depositary for the Securities for
such series ceases to be a clearing agency registered under the Securities
Exchange Act of 1934, as amended, or other applicable statute or regulation, the
Company shall appoint a successor Depositary with respect to such Global
Security. If a successor Depositary for such Global Security is not appointed by
the Company within 90 days after the Company receives such notice or becomes
aware of such ineligibility, the Company will execute, and the Trustee or its
agent, upon receipt of a Company Request for the authentication and delivery of
individual Securities of such series in exchange for such Global Security, will
authenticate and deliver, individual Securities of such series of like tenor and
terms in an aggregate principal amount equal to the principal amount of the
Global Security in exchange for such Global Security.

                (ii) The Company may at any time and in its sole discretion
determine that the Securities of any series or portion thereof issued or
issuable in the form of one or more Global Securities shall no longer be
represented by such Global Security or Securities. In such event the Company
will execute, and the Trustee, upon receipt of a Company Request for the
authentication and delivery of individual Securities of such series in exchange
in whole or in part for such Global Security, will authenticate and deliver
individual Securities of such series of like tenor and terms in definitive form
in an aggregate principal amount equal to the principal amount of such Global
Security
   26
                                                                              19



or Securities representing such series or portion thereof in exchange for such
Global Security or Securities.

              (iii) If specified by the Company pursuant to Sections 202 and 301
with respect to Securities issued or issuable in the form of a Global Security,
the Depositary for such Global Security may surrender such Global Security in
exchange in whole or in part for individual Securities of such series of like
tenor and terms in definitive form on such terms as are acceptable to the
Company and such Depositary. Thereupon the Company shall execute, and the
Trustee or its agent shall authenticate and deliver, without service charge, (1)
to each Person specified by such Depositary a new Security or Securities of the
same series of like tenor and terms and of any authorized denomination as
requested by such Person in aggregate principal amount equal to and in exchange
for such Person's beneficial interest in the Global Security; and (2) to such
Depositary a new Global Security of like tenor and terms and in an authorized
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 the Holders thereof.

                (iv) In any exchange provided for in any of the preceding three
paragraphs, the Company will execute and the Trustee or its agent will
authenticate and deliver individual Securities in definitive registered form in
authorized denominations. Upon the exchange of the entire principal amount of a
Global Security for individual Securities, such Global Security shall be
cancelled by the Trustee or its agent. Except as provided in the preceding
paragraph, 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 or the
Security Registrar. The Trustee or the Security Registrar shall deliver such
Securities to the Persons in whose names such Securities are so registered.
   27
                                                                              20

Series; Terms of Particular Series. The aggregate principal amount of Securities
which may be authenticated and delivered and Outstanding under this Indenture is
not limited.

                  The Securities may be issued in one or more series up to an
aggregate principal amount of Securities as from time to time may be authorized
by the Board of Directors. All Securities of each series under this Indenture
shall in all respects be equally and ratably entitled to the benefits hereof
with respect to such series without preference, priority or distinction on
account of the actual time of the authentication and delivery or Stated Maturity
of the Securities of such series.

                  Each series of Securities shall be created either by or
pursuant to a Board Resolution or by or pursuant to an indenture supplemental
hereto. The Securities of each such series may bear such date or dates, be
payable at such place or places, have such Stated Maturity or Maturities, be
issuable at such premium over or discount from their face value, bear interest
at such rate or rates (which may be fixed or floating), from such date or dates,
payable in such installments and on such dates and at such place or places to
the Holders of Securities registered as such on such Regular Record Dates, or
may bear no interest, and may be redeemable or repayable at such Redemption
Price or Prices or Repayment Price or Prices, as the case may be, whether at the
option of the Holder or otherwise, and upon such terms, all as shall be provided
for in or pursuant to the Board Resolution or in or pursuant to the supplemental
indenture creating that series. There may also be established in or pursuant to
a Board Resolution or in or pursuant to a supplemental indenture prior to the
issuance of Securities of each such series, provision for:

                  (1) the exchange or conversion of the Securities of that
         series, at the option of the Holders thereof, for or into new
         Securities of a different series or other securities or other property,
         including shares of capital stock of the Company or any subsidiary of
         the Company or securities directly or indirectly convertible into or
         exchangeable for any such shares;

         such Securities shall or may be payable;

                  (4) if the principal of (and premium, if any) or interest, if

         European Currency Units) other than that in which the Securities are
         stated to be payable, the period or periods within which, and the terms
         and conditions upon which, such election may be made;

                  (5) if the amount of payments of principal of (and premium, if
         any) or interest, if any, on the Securities of such series may be
         determined with reference to an index based on (i) a currency or
         currencies or units based on or related to currencies (including
         European Currency Units) other than that in which the Securities are
         stated to be payable, (ii) changes in the price of one or more other
         securities or groups or indexes of securities or (iii) changes in the
         prices of one or more commodities or groups or indexes of commodities,
         or any combination of the foregoing, the manner in which such amounts
         shall be determined;

         Securities of that series is to be limited, such
         limitations;

                  (7) the exchange of Securities of that series, at the option
         of the Holders thereof, for other Securities of the same series of the

         be payable upon declaration of acceleration of the Maturity thereof
         pursuant to Section 502 or provable in bankruptcy pursuant to Section
         504;

         making any Event of Default set forth herein inapplicable to the
         Securities of that series);

         that shall be applicable to the Securities of such series (including a
         provision making any Section of such Article inapplicable to the
         Securities of such series);

                (12)  the applicability of Section 403 of this
         Indenture to the Securities of such series;

                (13) if the Securities of the series shall be issued in whole or
         in part in the form of a Global Security or Global Securities, the
         terms and conditions, if any, upon which such Global Security or Global
         Securities may be exchanged in whole or in part for other individual
         Securities; and the Depositary for such Global Security or Global
         Securities (if other than the Depositary specified in Section 101
         hereof);

                (14) the subordination of the Securities of such series to any
         other indebtedness of the Company, including without limitation, the
         Securities of any other series; and

                (15)  any other terms of the series, which shall
         not be inconsistent with the provisions of this
         Indenture,

   30
                                                                              23



all upon such terms as may be determined in or pursuant to a Board Resolution or
in or pursuant to a supplemental indenture with respect to such series. All
Securities of the same series shall be substantially identical in tenor and
effect, except as to denomination.

                  The form of the Securities of each series shall be established
pursuant to the provisions of this Indenture in or pursuant to the Board
Resolution or in or pursuant to the supplemental indenture creating such series.
The Securities of each series shall be distinguished from the Securities of each
other series in such manner, reasonably satisfactory to the Trustee, as the
Board of Directors may determine.

                  Unless otherwise provided with respect to Securities of a
particular series, the Securities of any series may only be issuable in
registered form, without coupons.

                  Any terms or provisions in respect of the Securities of any
series issued under this Indenture may be determined pursuant to this Section by
providing in a Board Resolution or supplemental indenture for the method by
which such terms or provisions shall be determined.

                  Section 302. Denominations. The Securities of each series
shall be issuable in such denominations and currency as shall be provided in the
provisions of this Indenture or in or pursuant to the Board Resolution or the
supplemental indenture creating such series. In the absence of any such
provisions with respect to the Securities of any series, the Securities of that
series shall be issuable only in fully registered form in denominations of
$1,000 and any integral multiple thereof.

                  Section 303. Execution, Authentication and Delivery and
Dating. The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its President, one of its Vice Presidents or its
Treasurer under its corporate seal reproduced thereon and attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities may be manual or facsimile.

                  Securities bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery
   31
                                                                              24




of such Securities or did not hold such offices at the date of such Securities.

                  At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Securities executed by the
Company to the Trustee for authentication; and the Trustee shall, upon Company
Order, authenticate and deliver such Securities as in this Indenture provided
and not otherwise.

                  Prior to any such authentication and delivery, the Trustee
shall be entitled to receive, in addition to any Officers' Certificate and
Opinion of Counsel required to be furnished to the Trustee pursuant to Section
102, and the Board Resolution and any certificate relating to the issuance of
the series of Securities required to be furnished pursuant to Section 202, an
Opinion of Counsel stating that:

                  (1) all instruments furnished to the Trustee conform to the
         requirements of the Indenture and constitute sufficient authority
         hereunder for the Trustee to authenticate and deliver such Securities;

                  (2) the form and terms (or in connection with the issuance of
         medium-term Securities under Section 311, the manner of determining the
         terms) of such Securities have been established in conformity with the
         provisions of this Indenture;

                  (3) all laws and requirements with respect to the execution
         and delivery by the Company of such Securities have been complied with,
         the Company has the corporate power to issue such Securities and such
         Securities have been duly authorized and delivered by the Company and,
         assuming due authentication and delivery by the Trustee, constitute
         legal, valid and binding obligations of the Company enforceable in
         accordance with their terms (subject, as to enforcement of remedies, to
         applicable bankruptcy, reorganization, insolvency, moratorium or other
         laws and legal principles affecting creditors' rights generally from
         time to time in effect and to general equitable principles, whether
         applied in an action at law or in equity) and entitled to the benefits
         of this Indenture, equally and ratably with all other Securities, if
         any, of such series Outstanding; and

   32
                                                                              25



                  (4) such other matters as the Trustee may reasonably request;


and, if the authentication and delivery relates to a new series of Securities
created by an indenture supplemental hereto, also stating that all laws and
requirements with respect to the form and execution by the Company of the
supplemental indenture with respect to that series of Securities have been
complied with, the Company has corporate power to execute and deliver any such
supplemental indenture and has taken all necessary corporate action for those
purposes and any such supplemental indenture has been executed and delivered and
constitutes the legal, valid and binding obligation of the Company enforceable
in accordance with its terms (subject, as to enforcement of remedies, to
applicable bankruptcy, reorganization, insolvency, moratorium or other laws and
legal principles affecting creditors' rights generally from time to time in
effect and to general equitable principles, whether applied in an action at law
or in equity).

                  The Trustee shall not be required to authenticate such
Securities if the issue thereof will adversely affect the Trustee's own rights,
duties or immunities under the Securities and this Indenture.

                  Unless otherwise provided in the form of Security for any
series, all Securities shall be dated the date of their authentication.

                  No Security shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for
herein executed by the Trustee by manual signature of an authorized signatory,
and such certificate upon any Security shall be conclusive evidence, and the
only evidence, that such Security has been duly authenticated and delivered
hereunder.

                  Section 304. Temporary Securities. Pending the preparation of
definitive Securities of any series, the Company may execute, and, upon receipt
of the documents required by Section 303, together with a Company Order, the
Trustee shall authenticate and deliver, temporary Securities which are printed,
lithographed, typewritten, mimeographed

   33
                                                                              26



or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

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

                  Section 305. Registration, Transfer and Exchange. The Company
shall keep or cause to be kept a register (herein sometimes referred to as the
"Security Register") in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of Securities, or of
Securities of a particular series, and for transfers of Securities or of
Securities of such series. Any such register shall be in written form or in any
other form capable of being converted into written form within a reasonable
time. At all reasonable times the information contained in such register or
registers shall be available for inspection by the Trustee at the office or
agency to be maintained by the Company as provided in Section 1002.

                  Subject to Section 204, upon surrender for transfer of any
Security of any series at the office or agency of the Company in a Place of
Payment, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of such series of any authorized denominations, of a like
aggregate principal amount and Stated Maturity and of like tenor and terms.
   34
                                                                              27



                  Subject to Section 204, at the option of the Holder,
Securities of any series may be exchanged for other Securities of such series of
any authorized denominations, of a like aggregate principal amount and Stated
Maturity and of like tenor and terms, upon surrender of the Securities to be
exchanged at such office or agency. Whenever any Securities are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Securityholder making the exchange is entitled
to receive.

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

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

                  Unless otherwise provided in the Security to be transferred or
exchanged, no service charge shall be made on any Securityholder for any
transfer or exchange of Securities, but the Company may (unless otherwise
provided in such Security) require payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in connection with any transfer
or exchange of Securities, other than exchanges pursuant to Section 304 or 906
not involving any transfer.

                  The Company shall not be required (i) to issue, transfer or
exchange any Security of any series during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities of such series selected for redemption under Section 1103 and ending
at the close of business on the date of such mailing, or (ii) to transfer or
exchange any Security so selected for redemption in whole or in part, except for
the portion of such Security not so selected for redemption.

                  None of the Company, the Trustee, any agent of the Trustee,
any Paying Agent or the Security Registrar will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of

   35
                                                                              28



beneficial ownership interests of a Global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

                  The Company initially appoints the Trustee to act as Security
Registrar for the Securities on its behalf. The Company may at any time and from
time to time authorize any Person to act as Security Registrar in place of the
Trustee with respect to any series of Securities issued under this Indenture.

                  Section 306. Mutilated, Destroyed, Lost and Stolen Securities.
If (i) any mutilated Security is surrendered to the Trustee, or the Company and
the Trustee receive evidence to their satisfaction of the destruction, loss or
theft of any Security, and (ii) there is delivered to the Company and the
Trustee such security or indemnity as may be required by them to save each of
them harmless, then, in the absence of notice to the Company or the Trustee that
such Security has been acquired by a bona fide purchaser, the Company shall
execute and upon its request the Trustee shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Security, a new Security of like tenor, series, Stated Maturity and principal
amount, bearing a number not contemporaneously Outstanding.

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

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

                  Every new Security issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of the same series duly issued hereunder.
   36
                                                                              29



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

                  Section 307. Payment of Interest; Interest Rights Preserved.
Unless otherwise provided with respect to such Security pursuant to Section 301,
interest on any Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest.

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

                  (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names any such Securities (or their
         respective Predecessor Securities) are registered at the close of
         business on a Special Record Date for the payment of such Defaulted
         Interest, which shall be fixed in the following manner. The Company
         shall notify the Trustee in writing of the amount of Defaulted Interest
         proposed to be paid on each such Security and the date of the proposed
         payment, and at the same time the Company shall deposit with the
         Trustee an amount of money equal to the aggregate amount proposed to be
         paid in respect of such Defaulted Interest or shall make arrangements
         satisfactory to the Trustee for such deposit prior to the date of the
         proposed payment, such money when deposited to be held in trust for the
         benefit of the Persons entitled to such Defaulted Interest as in this
         Clause provided. Thereupon the Trustee shall fix a Special Record Date
         for the payment of such Defaulted Interest which shall be not more than
         15 nor less than 10 days prior to the date of the proposed payment and
         not less than 10 days after the receipt by the Trustee of the notice of
         the proposed payment. The Trustee shall promptly notify the Company of
         such Special Record Date and, in the name and at the expense of the

   37
                                                                              30




         Company, shall cause notice of the proposed payment of such Defaulted
         Interest and the Special Record Date therefor to be mailed, first-class
         postage prepaid, to the Holder of each such Security at his address as
         it appears in the Security Register, not less than 10 days prior to
         such Special Record Date. Notice of the proposed payment of such
         Defaulted Interest and the Special Record Date therefor having been
         mailed as aforesaid, such Defaulted Interest shall be paid to the
         Persons in whose names such Securities (or their respective Predecessor
         Securities) are registered on such Special Record Date and shall no
         longer be payable pursuant to the following Clause (2).

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

                  If any installment of interest the Stated Maturity of which is
on or prior to the Redemption Date for any Security called for redemption
pursuant to Article Eleven is not paid or duly provided for on or prior to the
Redemption Date in accordance with the foregoing provisions of this Section,
such interest shall be payable as part of the Redemption Price of such
Securities.

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

                  Section 308. Persons Deemed Owners. The Company, the Trustee
and any agent of the Company or the Trustee may treat the Person in whose name
any Security is registered in the Security Register as the owner of such
Security for the purpose of receiving payment of principal of (and premium, if
any), and (subject to Section 307) interest on, such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.
   38
                                                                              31



                  Section 309. Cancellation. All Securities surrendered for
payment, redemption, transfer, conversion or exchange or credit against a
sinking fund shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee and, if not already cancelled, shall be promptly
cancelled by it. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and all Securities
so delivered shall be promptly cancelled by the Trustee. No Security shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section, except as expressly permitted by this Indenture. The Trustee
shall dispose of all cancelled Securities in accordance with its customary
procedures and shall deliver a certificate of such disposition to the Company.

                  Section 310. Computation of Interest. Unless otherwise
provided as contemplated in Section 301, interest on the Securities shall be
calculated on the basis of a 360-day year of twelve 30-day months.

                  Section 311. Medium-term Securities. Notwithstanding any
contrary provision herein, if all Securities of a series are not to be
originally issued at one time, it shall not be necessary for the Company to
deliver to the Trustee an Officers' Certificate, Board Resolution, supplemental
indenture, Opinion of Counsel or Company Request otherwise required pursuant to
Sections 202, 301 and 303 at or prior to the time of authentication of each
Security of such series if such documents are delivered to the Trustee or its
agent at or prior to the authentication upon original issuance of the first
Security of such series to be issued; provided that any subsequent request by
the Company to the Trustee to authenticate Securities of such series upon
original issuance shall constitute a representation and warranty by the Company
that as of the date of such request, the statements made in the Officers'
Certificate delivered pursuant to Section 102 shall be true and correct as if
made on such date.

                  An Officers' Certificate, supplemental indenture or Board
Resolution delivered by the Company to the Trustee in the circumstances set
forth in the preceding paragraph may provide that Securities which are the
subject thereof will be authenticated and delivered by the Trustee or its agent
on original issue from time to time upon the telephonic or written order of
persons designated in such Officers' Certificate, Board Resolution or
supplemental
   39
                                                                              32



indenture (any such telephonic instructions to be confirmed promptly in writing
by such persons) and that such persons are authorized to determine, consistent
with such Officers' Certificate, supplemental indenture or Board Resolution,
such terms and conditions of said Securities as are specified in such Officers'
Certificate, supplemental indenture or Board Resolution.

                           Satisfaction and Discharge

                  Section 401. Satisfaction and Discharge of Indenture. This
Indenture shall cease to be of further effect with respect to any series of
Securities (except as to any surviving rights of conversion, transfer or
exchange of Securities of such series expressly provided for herein or in the
form of Security for such series), and the Trustee, on demand of and at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture as to such series, when

                  (1) either

                           (A) all Securities of that series theretofore

                  series which have been destroyed, lost or stolen and which
                  have been replaced or paid as provided in Section 306, and
                  (ii) Securities of such series for whose payment money has

                           (B) all such Securities of that series not
                  theretofore delivered to the Trustee cancelled or
                  for cancellation

                                    (i) have become due and payable, or

                      Stated Maturity within one year, or

                      redemption by the Trustee in the name, and at the expense,
                      of the Company,

and the Company, in the case of (i), (ii) or (iii) above, has deposited or
caused to be deposited with the Trustee as trust funds in trust for the purpose
an amount sufficient to pay and discharge the entire indebtedness on such
Securities not theretofore delivered to the Trustee cancelled or for
cancellation, for principal (and premium, if any) and interest to the date of
such deposit (in the case of Securities which have become due and payable), or
to the Stated Maturity or Redemption Date, as the case may be;

                  (2) the Company has paid or caused to be paid all other sums
         payable hereunder by the Company with respect to the Securities of such
         series; and

                  (3) the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel each stating that all conditions
         precedent herein provided for relating to the satisfaction and
         discharge of this Indenture with respect to the Securities of such
         series have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture with respect to
any series of Securities, the obligations of the Company to the Trustee with
respect to that series under Section 607 shall survive and the obligations of
the Trustee under Sections 402 and 1003 shall survive.

                  Section 402. Application of Trust Money. All money and
obligations deposited with the Trustee pursuant to Section 401 or Section 403
and all money received by the Trustee in respect of such obligations shall be
held in trust and applied by it, in accordance with the provisions of the series
of Securities in respect of which it was deposited and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal (and premium, if any) and interest for whose
payment such money and obligations have been deposited with or received by the
Trustee; but such money and obligations need not be segregated from other funds
except to the extent required by law.

                                                                              34



                  Section 403. Satisfaction, Discharge and Defeasance of
Securities of any Series. If this Section 403 is specified, as contemplated by
Section 301, to be applicable to Securities of any series, the Company shall be
deemed to have paid and discharged the entire indebtedness on all the Securities
of any such series at the time outstanding, and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging satisfaction,
discharge and defeasance of such indebtedness, when

                  (1) either

                           (A) with respect to all Securities of such
                  series at the time outstanding,

                                    (i) the Company has deposited or caused to
                           be deposited with the Trustee as trust funds in trust
                           for such purpose an amount sufficient, together with
                           any obligations deposited pursuant to clause (ii)
                           below, to pay and discharge the entire indebtedness
                           on all such Securities for principal (and premium, if
                           any) and interest, on the days on which such
                           principal (and premium, if any) or interest, as the
                           case may be, is due and payable in accordance with
                           the terms of this Indenture and such Securities, to
                           the date of maturity or date of redemption thereof as
                           contemplated by the penultimate paragraph of this
                           Section 403, as the case may be; or

                                  (ii) the Company has deposited or caused to be
                           deposited with the Trustee as obligations in trust
                           for such purpose such amount of direct obligations
                           of, or obligations the principal of and interest on
                           which are fully guaranteed by, the government which
                           issued the currency in which such Securities are
                           denominated (other than such obligations as are
                           redeemable at the option of the issuer thereof) as
                           will, together with the income to accrue thereon
                           without consideration of any reinvestment thereof, be
                           sufficient, in the written opinion of a firm of
                           nationally recognized independent public accountants
                           (which may be the Company's auditors) delivered to
                           the Trustee, together with any funds deposited
                           pursuant to clause (i) above, to pay and discharge
                           the
   42
                                                                              35



                           entire indebtedness on all such Securities for
                           principal (and premium, if any) and interest, on the
                           days on which such principal (and premium, if any) or
                           interest, as the case may be, is due and payable in
                           accordance with the terms of this Indenture and such
                           Securities, to the date of maturity or date of
                           redemption thereof as contemplated by the penultimate
                           paragraph of this Section 403, as the case may be; or

                           (B) the Company has properly fulfilled such other
                  means of satisfaction and discharge as is specified, as
                  contemplated by Section 301, to be applicable to the
                  Securities of such series;

                  (2) the Company has paid or caused to be paid all other sums
         payable with respect to the Securities of such series at the time
         Outstanding;

                  (3) such deposit will not result in a breach or violation of,
         or constitute a default under, this Indenture or any other agreement or
         instrument to which the Company is a party or by which it is bound;

                  (4) no Event of Default or event which, after notice or lapse
         of time or both, would become an Event of Default shall have occurred
         and be continuing on the date of such deposit; and

                  (5) the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent herein provided for relating to the satisfaction, discharge
         and defeasance of the entire indebtedness on all Securities of any such
         series at the time Outstanding have been complied with.

                  Any deposits with the Trustee referred to in Section 403(1)(A)
above shall be irrevocable. If any Securities of such series at the time
outstanding are to be redeemed prior to their Stated Maturity, whether pursuant
to any optional redemption provisions or in accordance with any mandatory
sinking fund requirement, the Company shall make such arrangements as are
satisfactory to the Trustee for the giving of notice of redemption by the
Trustee in the name, and at the expense, of the Company.
   43
                                                                              36



                  Upon the satisfaction of the conditions set forth in this
Section 403 with respect to all the Securities of any series at the time
Outstanding, the terms and conditions of such series, including the terms and
conditions with respect thereto set forth in this Indenture (except as to any
surviving rights of conversion, transfer or exchange of Securities of such
series expressly provided for herein or in the form of Security for such
series), shall no longer be binding upon, or applicable to, the Company,
provided that the Company shall not be discharged from any payment obligations
in respect of Securities of such series which are deemed not to be Outstanding
under clause (iii) of the definition thereof if such obligations continue to be
valid obligations of the Company under applicable law.

                  Notwithstanding the satisfaction of the conditions set forth
in this Section 403 with respect to all Securities of any series at the time
Outstanding, the obligations of the Company to the Trustee with respect to that
series under Section 607 and the obligations of the Trustee with respect to that
series under Section 402 and 1003 shall survive.


                                  ARTICLE FIVE

                                    Remedies

                  Section 501. Events of Default. "Event of Default", wherever
used herein, means with respect to any series of Securities any one of the
following events (whatever the reason for such Event of Default and whether it
shall be voluntary or involuntary or be effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation
of any administrative or governmental body), unless such event is either
inapplicable to a particular series or it is specifically deleted or modified in
the supplemental indenture creating such series of Securities or in the form of
Security for such series:

                  (1) default in the payment of any interest upon any Security
         of that series when it becomes due and payable, and continuance of such
         default for a period of 30 days; or

                  (2) default in the payment of the principal of (or
         premium, if any, on) any Security of that series at its
         Maturity; or

   44
                                                                              37



                  (3) default in the payment of any sinking or purchase fund or
         analogous obligation when the same becomes due by the terms of the

         warranty of the Company in this Indenture in respect of the Securities
         of such series (other than a covenant or warranty in respect of the
         Securities of such series a default in the performance of which or the
         breach of which is elsewhere in this Section specifically dealt with),
         all of such covenants and warranties in the Indenture which are not
         expressly stated to be for the benefit of a particular series of
         Securities being deemed in respect of the Securities of all series for
         this purpose, and continuance of such default or breach for a period of
         90 days after there has been given, by registered or certified mail, to
         the Company by the Trustee or to the Company and the Trustee by the
         Holders of at least 25% in principal amount of the Outstanding
         Securities of such series, a written notice specifying such default or
         breach and requiring it to be remedied and stating that such notice is
         a "Notice of Default" hereunder; or

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

                  (6) the consent by the Company to the institution of
         bankruptcy or insolvency proceedings against it, or the filing by it of
         a petition or answer or consent seeking reorganization or relief under
         the Federal Bankruptcy Code or any other applicable Federal or State
         law, or the consent by it to the filing of any

   45
                                                                              38



         such petition or to the appointment of a receiver, liquidator,
         assignee, trustee, sequestrator (or other similar official) of the
         Company or of any substantial part of its property, or the making by it
         of an assignment for the benefit of creditors, or the admission by it
         in writing of its inability to pay its debts generally as they become
         due, or the taking of corporate action by the Company in furtherance of
         any such action; or

                  (7) any other Event of Default provided in the supplemental
         indenture under which such series of Securities is issued or in the
         form of Security for such series.

                  Section 502. Acceleration of Maturity; Rescission and
Annulment. If an Event of Default described in paragraph (1), (2), (3), (4) or
(7) (if the Event of Default under paragraph (4) or (7) is with respect to less
than all series of Securities then Outstanding) of Section 501 occurs and is
continuing with respect to any series, then and in each and every such case,
unless the principal of all the Securities of such series shall have already
become due and payable, either the Trustee or the Holders of not less than 25%
in aggregate principal amount of the Securities of such series then Outstanding
hereunder (each such series acting as a separate class), by notice in writing to
the Company (and to the Trustee if given by Holders), may declare the principal
amount (or, if the Securities of such series are Original Issue Discount
Securities, such portion of the principal amount as may be specified in the
terms of that series) of all the Securities of such series then Outstanding and
all accrued interest thereon to be due and payable immediately, and upon any
such declaration the same shall become and shall be immediately due and payable,
anything in this Indenture or in the Securities of such series contained to the
contrary notwithstanding. If an Event of Default described in paragraph (4) or
(7) (if the Event of Default under paragraph (4) or (7) is with respect to all
series of Securities then Outstanding), (5) or (6) of Section 501 occurs and is
continuing, then and in each and every such case, unless the principal of all
the Securities shall have already become due and payable, either the Trustee or
the Holders of not less than 25% in aggregate principal amount of all the
Securities then Outstanding hereunder (treated as one class), by notice in
writing to the Company (and to the Trustee if given by Holders), may declare the
principal amount (or, if any Securities are Original Issue Discount Securities,
such portion of the

   46
                                                                              39



principal amount as may be specified in the terms thereof) of all the Securities
then Outstanding and all accrued interest thereon to be due and payable
immediately, and upon any such declaration the same shall become and shall be
immediately due and payable, anything in this Indenture or in the Securities
contained to the contrary notwithstanding.

                  At any time after such a declaration of acceleration has been
made with respect to the Securities of any series and before a judgment or
decree for payment of the money due has been obtained by the Trustee as
hereinafter in this Article provided, the Holders of a majority in principal
amount of the Outstanding Securities of such series, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its
consequences if

                  (1) the Company has paid or deposited with the
         Trustee a sum sufficient to pay

                           (A) all overdue installments of interest on
                  the Securities of such series,

                           (B) the principal of (and premium, if any, on) any
                  Securities of such series which have become due otherwise than
                  by such declaration of acceleration, and interest thereon at
                  the rate or rates prescribed therefor by the terms of the
                  Securities of such series, to the extent that payment of such
                  interest is lawful,

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

                           (D) all sums paid or advanced by the Trustee
                  hereunder and the reasonable compensation, expenses,
                  disbursements and advances of the Trustee, its agents and
                  counsel and all other amounts due the Trustee under Section
                  607;

and

                  (2) all Events of Default with respect to such series of
         Securities, other than the nonpayment of the principal of the
         Securities of such series which have

   47
                                                                              40




         become due solely by such acceleration, have been cured or waived as
         provided in Section 513.

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

                  Section 503.  Collection of Indebtedness and Suits
for Enforcement by Trustee.  The Company covenants that if

                  (1) default is made in the payment of any installment of
         interest on any Security of any series when such interest becomes due
         and payable, or

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

                  (3) default is made in the payment of any sinking or purchase
         fund or analogous obligation when the same becomes due by the terms of
         the Securities of any series,

and any such default continues for any period of grace provided with respect to
the Securities of such series, the Company will, upon demand of the Trustee, pay
to it, for the benefit of the Holder of any such Security (or the Holders of any
such series in the case of Clause (3) above), the whole amount then due and
payable on any such Security (or on the Securities of any such series in the
case of Clause (3) above) for principal (and premium, if any) and interest, with
interest, to the extent that payment of such interest shall be legally
enforceable, upon the overdue principal (and premium, if any) and upon overdue
installments of interest, at such rate or rates as may be prescribed therefor by
the terms of any such Security (or of Securities of any such series in the case
of Clause (3) above); and, in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel and all other amounts due the Trustee under Section 607.

                  If the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, and may prosecute such proceeding to judgment or final decree, and may
enforce the same against the Company or any

   48
                                                                              41



other obligor upon the Securities of such series and collect the money adjudged
or decreed to be payable in the manner provided by law out of the property of
the Company or any other obligor upon such Securities, wherever situated.

                  If an Event of Default with respect to any series of
Securities occurs and is continuing, the Trustee may in its discretion proceed
to protect and enforce its rights and the rights of the Holders of Securities of
such series by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

                  Section 504. Trustee May File Proofs of Claim. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company or any other obligor upon the Securities or
the property of the Company or of such other obligor or their creditors, the
Trustee (irrespective of whether the principal of the Securities shall then be
due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand on the Company
for the payment of overdue principal or interest) shall be entitled and
empowered, by intervention in such proceedings or otherwise,

                  (i) to file and prove a claim for the whole amount of
         principal (and premium, if any) and interest owing and unpaid in
         respect of the Securities and to file such other papers or documents as
         may be necessary and advisable in order to have the claims of the
         Trustee (including any claim for the reasonable compensation, expenses,
         disbursements and advances of the Trustee, its agents and counsel and
         all other amounts due the Trustee under Section 607) and of the
         Securityholders allowed in such judicial proceeding, and

                  (ii) to collect and receive any moneys or other property
         payable or deliverable on any such claims and to distribute the same;

and any receiver, assignee, trustee, liquidator, sequestrator (or other similar
official) in any such judicial proceeding is hereby authorized by each
Securityholder to make such payment to the Trustee and in the event that the
Trustee shall consent to the making of

   49
                                                                              42



such payments directly to the Securityholders, to pay to the Trustee any amount
due to it for the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel, and any other amounts due the Trustee
under Section 607.

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

                  Section 505. Trustee May Enforce Claims Without Possession of
Securities. All rights of action and claims under this Indenture or the
Securities of any series may be prosecuted and enforced by the Trustee without
the possession of any of the Securities of such series or the production thereof
in any proceeding relating thereto, and any such proceeding instituted by the
Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agent and
counsel, be for the ratable benefit of the Holders of the Securities of the
series in respect of which such judgment has been recovered.

                  Section 506. Application of Money Collected. Any money
collected by the Trustee with respect to a series of Securities pursuant to this
Article shall be applied in the following order, at the date or dates fixed by
the Trustee and, in case of the distribution of such money on account of
principal (or premium, if any) or interest, upon presentation of the Securities
of such series and the notation thereon of the payment if only partially paid
and upon surrender thereof if fully paid:

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

                  SECOND: To the payment of the amounts then due and unpaid upon
the Securities of that series for principal (and premium, if any) and interest,
in respect of which or for the benefit of which such money has been collected,
ratably, without preference or priority of any kind, according to the amounts
due and payable on such Securities
   50
                                                                              43



for principal (and premium, if any) and interest, respectively.

                  Section 507. Limitation on Suits. No Holder of any Security of
any series shall have any right to institute any proceeding, judicial or
otherwise, with respect to this Indenture, or for the appointment of a receiver
or trustee, or for any other remedy hereunder, unless

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

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

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

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

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

it being understood and intended that no one or more Holders of Securities of
such series shall have any right in any manner whatever by virtue of, or by
availing of, any provision of this Indenture to affect, disturb or prejudice the
rights of any other Holders of Securities of such series, or to obtain or to
seek to obtain priority or preference over any other such Holders or to enforce
any right under this Indenture, except in the manner herein provided and for the
equal and proportionate benefit of all the Holders of all Securities of such
series.

                  Section 508. Unconditional Right of Securityholders to
Receive Principal, Premium and Interest. Notwithstanding any other provisions
in this Indenture, the Holder of any Security shall have the right, which is
absolute and unconditional, to receive payment of the
   51
                                                                              44



principal of (and premium, if any) and (subject to Section 307) interest on such
Security on the respective Stated Maturities expressed in such Security (or, in
the case of redemption or repayment, on the Redemption Date or Repayment Date,
as the case may be) and to institute suit for the enforcement of any such
payment, and such right shall not be impaired without the consent of such
Holder.

                  Section 509. Restoration of Rights and Remedies. If the
Trustee or any Securityholder has instituted any proceeding to enforce any right
or remedy under this Indenture and such proceeding has been discontinued or
abandoned for any reason, then and in every such case the Company, the Trustee
and the Securityholders shall, subject to any determination in such proceeding,
be restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies of the Trustee and the Securityholders shall
continue as though no such proceeding had been instituted.

                  Section 510. Rights and Remedies Cumulative. No right or
remedy herein conferred upon or reserved to the Trustee or to the
Securityholders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

                  Section 511. Delay or Omission Not Waiver. No delay or
omission of the Trustee or of any Holder of any Security to exercise any right
or remedy accruing upon any Event of Default shall impair any such right or
remedy or constitute a waiver of any such Event of Default or an acquiescence
therein. Every right and remedy given by this Article or by law to the Trustee
or to the Securityholders may be exercised from time to time, and as often as
may be deemed expedient, by the Trustee or by the Securityholders, as the case
may be.

                  Section 512. Control by Securityholders. The Holders of a
majority in principal amount of the Outstanding Securities of any series shall
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or exercising any trust or

   52
                                                                              45



power conferred on the Trustee with respect to the Securities of such series,
provided that

                  (1) the Trustee shall have the right to decline to follow any
         such direction if the Trustee, being advised by counsel, determines
         that the action so directed may not lawfully be taken or would conflict
         with this Indenture or if the Trustee in good faith shall, by a
         Responsible Officer, determine that the proceedings so directed would
         involve it in personal liability or be unjustly prejudicial to the
         Holders not taking part in such direction, and

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

                  Section 513. Waiver of Past Defaults. The Holders of not less
than a majority in principal amount of the Outstanding Securities of any series
may on behalf of the Holders of all the Securities of such series waive any past
default hereunder with respect to such series and its consequences, except a
default not theretofore cured

                  (1) in the payment of the principal of (or premium, if any) or
         interest on any Security of such series, or in the payment of any
         sinking or purchase fund or analogous obligation with respect to the
         Securities of such series, or

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

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

                  Section 514. Undertaking for Costs. All parties to this
Indenture agree, and each Holder of any Security by his acceptance thereof shall
be deemed to have agreed, that any court may in its discretion require, in any
suit for the enforcement of any right or remedy under this Indenture, or in any
suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of
such
   53
                                                                              46



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

                  Section 515. Waiver of Stay or Extension Laws. The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law wherever enacted, now or at
any time hereafter in force, which may affect the covenants or the performance
of this Indenture; and the Company (to the extent that it may lawfully do so)
hereby expressly waives all benefit or advantage of any such law, and covenants
that it will not hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.


                                   ARTICLE SIX

                                   The Trustee

                  Section 601. Certain Duties and Responsibilities. (a) Except
during the continuance of an Event of Default with respect to any series of
Securities,

                  (1) the Trustee undertakes to perform such duties and only
         such duties as are specifically set forth in this Indenture with
         respect to the Securities of such series, and no implied covenants or
         obligations shall be read into this Indenture against the Trustee; and

                  (2) in the absence of bad faith on its part, the Trustee may,
         with respect to Securities of such series, conclusively rely, as to the
         truth of the statements

   54
                                                                              47



         and the correctness of the opinions expressed therein, upon
         certificates or opinions furnished to the Trustee and conforming to the
         requirements of this Indenture; but in the case of any such
         certificates or opinions which by any provision hereof are specifically
         required to be furnished to the Trustee, the Trustee shall be under a
         duty to examine the same to determine whether or not they conform to
         the requirements of this Indenture.

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

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

                  (1) this Subsection shall not be construed to limit the effect
         of Subsection (a) of this Section;

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

                  (3) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         direction of the Holders of a majority in principal amount of the
         Outstanding Securities of any series relating to the time, method and
         place of conducting any proceeding for any remedy available to the
         Trustee, or exercising any trust or power conferred upon the Trustee,
         under this Indenture with respect to the Securities of such series; and

                  (4) no provision of this Indenture shall require the Trustee
         to expend or risk its own funds or otherwise incur any financial
         liability in the performance of any of its duties hereunder, or in the
         exercise of any of its rights or powers, if it shall have reasonable
         grounds for believing that repayment of

   55
                                                                              48



         such funds or adequate indemnity against such risk or liability is not
         reasonably assured to it.

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

                  Section 602. Notice of Defaults. Within 90 days after the
occurrence of any default hereunder with respect to Securities of any series,
the Trustee shall transmit by mail to all Securityholders of such series, as
their names and addresses appear in the Security Register, notice of such
default hereunder known to the Trustee, unless such default shall have been
cured or waived; provided, however, that, except in the case of a default in the
payment of the principal of (or premium, if any) or interest on any Security of
such series or in the payment of any sinking or purchase fund installment or
analogous obligation with respect to Securities of such series, the Trustee
shall be protected in withholding such notice if and so long as the board of
directors, the executive committee or a trust committee of directors and/or
Responsible Officers of the Trustee in good faith determine that the withholding
of such notice is in the interests of the Securityholders of such series; and
provided, further, that in the case of any default of the character specified in
Section 501(4) with respect to Securities of such series no such notice to
Securityholders of such series shall be given until at least 90 days after the
occurrence thereof. For the purpose of this Section, the term "default", with
respect to Securities of any series, means any event which is, or after notice
or lapse of time or both would become, an Event of Default with respect to
Securities of such series.

                  Section 603.  Certain Rights of Trustee.  Except
as otherwise provided in Section 601:

                  (a) the Trustee may rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture or
other paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties;

                  (b) any request or direction of the Company mentioned herein
shall be sufficiently evidenced by a Company Request or Company Order and any
resolution of the
   56
                                                                              49



Board of Directors may be sufficiently evidenced by a Board Resolution;

                  (c) whenever in the administration of this Indenture the
Trustee shall deem it desirable that a matter be proved or established prior to
taking, suffering or omitting any action hereunder, the Trustee (unless other
evidence be herein specifically prescribed) may, in the absence of bad faith on
its part, rely upon an Officers' Certificate;

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

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

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

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

                  Section 604. Not Responsible for Recitals or Issuance of
Securities. The recitals contained herein and in the Securities, except the
certificates of authentication, shall be taken as the statements of the
Company,


   57
                                                                              50



and the Trustee assumes no responsibility for their correctness. The Trustee
makes no representations as to the validity or sufficiency of this Indenture or
of the Securities. The Trustee shall not be accountable for the use or
application by the Company of Securities or the proceeds thereof.

                  Section 605. May Hold Securities. The Trustee, any Paying
Agent, the Security Registrar or any other agent of the Company, in its
individual or any other capacity, may become the owner or pledgee of Securities
and, subject to Sections 608 and 613, may otherwise deal with the Company with
the same rights it would have if it were not Trustee, Paying Agent, Security
Registrar or such other agent.

                  Section 606. Money Held in Trust. Money held by the Trustee in
trust hereunder need not be segregated from other funds except to the extent
required by law. The Trustee shall be under no liability for interest on any
money received by it hereunder except as otherwise agreed with the Company.

                  Section 607.  Compensation and Reimbursement.  The
Company agrees

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

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

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

   58
                                                                              51



                  As security for the performance of the obligations of the
Company under this Section the Trustee shall have a lien prior to the Securities
upon all property and funds held or collected by the Trustee as such, except
funds held in trust for the payment of principal of (and premium, if any) or
interest on particular Securities.

                  Section 608. Disqualification; Conflicting Interests. The
Trustee for the Securities of any series issued hereunder shall be subject to
the provisions of Section 310(b) of the Trust Indenture Act during the period of
time provided for therein. In determining whether the Trustee has a conflicting
interest as defined in Section 310(b) of the Trust Indenture Act with respect to
the Securities of any series, there shall be excluded for purposes of the
conflicting interest provisions of such Section 310(b) the Securities of every
other series issued under this Indenture (i) every series of securities issued
under the Indenture dated as of May 14, 1996, between Union Pacific Corporation

the Commission the application referred to in the second to last paragraph of
Section 310(b) of the Trust Indenture Act.

                  Section 609. Corporate Trustee Required; Eligibility. There
shall at all times be a Trustee hereunder with respect to each series of
Securities, which shall be a corporation organized and doing business under the
laws of the United States of America or of any State, authorized under such laws
to exercise corporate trust powers, having a combined capital and surplus of at
least $50,000,000, and subject to supervision or examination by Federal or State
authority. If such corporation publishes reports of condition at least annually,
pursuant to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee with respect to any series of Securities shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

                  Section 610. Resignation and Removal; Appointment of
Successor. (a) No resignation or removal of the Trustee and no appointment of a

acceptance of appointment by the successor Trustee under Section 611.

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

                  (c) The Trustee may be removed with respect to any series of
Securities at any time by Act of the Holders of a majority in principal amount
of the Outstanding Securities of that series, delivered to the Trustee and to
the Company.
   60
                                                                              53



                  (d)  If at any time:

                  (1) the Trustee shall fail to comply with Section 310(b) of
         the Trust Indenture Act pursuant to Section 608(a) with respect to any
         series of Securities after written request therefor by the Company or
         by any Securityholder who has been a bona fide Holder of a Security of
         that series for at least 6 months, or

                  (2) the Trustee shall cease to be eligible under Section 609
         with respect to any series of Securities and shall fail to resign after
         written request therefor by the Company or by any such Securityholder,
         or

                  (3) the Trustee shall become incapable of acting with respect
         to any series of Securities, or

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

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee, with respect to the series, or in the case of Clause (4), with respect
to all series, or (ii) subject to Section 514, any Securityholder who has been a
bona fide Holder of a Security of such series for at least 6 months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee with respect to the series, or, in the case of Clause (4),
with respect to all series.

                  (e) If the Trustee shall resign, be removed or become
incapable of acting with respect to any series of Securities, or if a vacancy
shall occur in the office of the Trustee with respect to any series of
Securities for any cause, the Company, by a Board Resolution, shall promptly
appoint a successor Trustee for that series of Securities. If, within one year
after such resignation, removal or incapacity, or the occurrence of such
vacancy, a successor Trustee with respect to such series of Securities shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment, become the successor Trustee

   61
                                                                              54



with respect to such series and supersede the successor Trustee appointed by the
Company with respect to such series. If no successor Trustee with respect to
such series shall have been so appointed by the Company or the Securityholders
of such series and accepted appointment in the manner hereinafter provided, any
Securityholder who has been a bona fide Holder of a Security of that series for
at least 6 months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the appointment of a successor
Trustee with respect to such series.

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

                  Section 611. Acceptance of Appointment by Successor. Every
successor Trustee appointed hereunder shall execute, acknowledge and deliver to
the Company and to the predecessor Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the predecessor Trustee
shall become effective with respect to any series as to which it is resigning or
being removed as Trustee, and such successor Trustee, without any further act,
deed or conveyance, shall become vested with all the rights, powers, trusts and
duties of the predecessor Trustee with respect to any such series; but, on
request of the Company or the successor Trustee, such predecessor Trustee shall,
upon payment of its reasonable charges, if any, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and
trusts of the predecessor Trustee, and shall duly assign, transfer and deliver
to such successor Trustee all property and money held by such predecessor
Trustee hereunder with respect to all or any such series, subject nevertheless
to its lien, if any, provided for in Section 607. Upon request of any such
successor Trustee, the Company shall execute any and all instruments for more
fully and certainly vesting in and confirming to such successor Trustee all such
rights, powers and trusts.

                  In case of the appointment hereunder of a successor Trustee
with respect to the Securities of one or
   62
                                                                              55



more (but not all) series, the Company, the predecessor Trustee and each
successor Trustee with respect to the Securities of any applicable series shall
execute and deliver an indenture supplemental hereto which shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the predecessor Trustee with respect to the
Securities of any series as to which the predecessor Trustee is not being
succeeded shall continue to be vested in the predecessor Trustee, and 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.

                  No successor Trustee with respect to any series of Securities
shall accept its appointment unless at the time of such acceptance such
successor Trustee shall be qualified and eligible with respect to that series
under this Article.

                  Section 612. Merger, Conversion, Consolidation or Succession
to Business. Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

                  Section 613. Preferential Collection of Claims Against
Company. (a) Subject to Subsection (b) of this Section, if the Trustee shall be
or shall become a creditor, directly or indirectly, secured or unsecured, of the
Company within 3 months prior to a default, as defined in Subsection (c) of this
Section, or subsequent to such a default, then, unless and until such default
shall be cured,
   63
                                                                              56



the Trustee shall set apart and hold in a special account for the benefit of the
Trustee individually, the Holders of the Securities and the holders of other
indenture securities (as defined in Subsection (c) of this Section):

                  (1) an amount equal to any and all reductions in the amount
         due and owing upon any claim as such creditor in respect of principal
         or interest, effected after the beginning of such 3-month period and
         valid as against the Company and its other creditors, except any such
         reduction resulting from the receipt or disposition of any property
         described in paragraph (2) of this Subsection, or from the exercise of
         any right of set-off which the Trustee could have exercised if a
         petition in bankruptcy had been filed by or against the Company upon
         the date of such default; and

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

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

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

                      (B) to realize, for its own account, upon any property 
                    held by it as security for any such claim, if such property
                    was so held prior to the beginning of such 3-month period;

                      (C) to realize, for its own account, but only to the
                  extent of the claim hereinafter mentioned, upon any property
                  held by it as security for any

   64
                                                                              57



                  such claim, if such claim was created after the beginning of
                  such 3-month period and such property was received as security
                  therefor simultaneously with the creation thereof, and if the
                  Trustee shall sustain the burden of proving that at the time
                  such property was so received the Trustee had no reasonable
                  cause to believe that a default as defined in Subsection (c)
                  of this Section would occur within 3 months; or

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

                  For the purposes of paragraphs (B), (C) and (D), property
substituted after the beginning of such 3-month period for property held as
security at the time of such substitution shall, to the extent of the fair value
of the property released, have the same status as the property released, and, to
the extent that any claim referred to in any of such paragraphs is created in
renewal of or in substitution for or for the purpose of repaying or refunding
any pre-existing claim of the Trustee as such creditor, such claim shall have
the same status as such pre-existing claim.

                  If the Trustee shall be required to account, the funds and
property held in such special account and the proceeds thereof shall be
apportioned between the Trustee, the Securityholders and the holders of other
indenture securities in such manner that the Trustee, the Securityholders and
the holders of other indenture securities realize, as a result of payments from
such special account and payments of dividends on claims filed against the
Company in bankruptcy or receivership or in proceedings for reorganization
pursuant to the Federal Bankruptcy Act or applicable State law, the same
percentage of their respective claims, figured before crediting to the claim of
the Trustee anything on account of the receipt by it from the Company of the
funds and property in such special account and before crediting to the
respective claims of the Trustee and the Securityholders and the holders of
other indenture securities dividends on claims filed against the Company in
bankruptcy or receivership or in proceedings for reorganization pursuant to the
Federal Bankruptcy Act or applicable State law, but after crediting thereon
receipts on account of the indebtedness represented by their
   65
                                                                              58



respective claims from all sources other than from such dividends and from the
funds and property so held in such special account. As used in this paragraph,
with respect to any claim, the term "dividends" shall include any distribution
with respect to such claim, in bankruptcy or receivership or proceedings for
reorganization pursuant to the Federal Bankruptcy Act or applicable State law,
whether such distribution is made in cash, securities, or other property, but
shall not include any such distribution with respect to the secured portion, if
any, of such claim. The court in which such bankruptcy, receivership or
proceedings for reorganization is pending shall have jurisdiction (i) to
apportion between the Trustee and the Securityholders and the holders of other
indenture securities in accordance with the provisions of this paragraph, the
funds and property held in such special account and proceeds thereof, or (ii) in
lieu of such apportionment, in whole or in part, to give to the provisions of
this paragraph due consideration in determining the fairness of the
distributions to be made to the Trustee and the Securityholders and the holders
of other indenture securities with respect to their respective claims, in which
event it shall not be necessary to liquidate or to appraise the value of any
securities or other property held in such special account or as security for any
such claim, or to make a specific allocation of such distributions as between
the secured and unsecured portions of such claims, or otherwise to apply the
provisions of this paragraph as a mathematical formula.

                  Any Trustee which has resigned or been removed after the
beginning of such 3-month period shall be subject to the provisions of this
Subsection as though such resignation or removal had not occurred. If any
Trustee has resigned or been removed prior to the beginning of such 3-month
period, it shall be subject to the provisions of this Subsection if and only if
the following conditions exist:

                           (i) the receipt of property or reduction of claim,
                  which would have given rise to the obligation to account, if
                  such Trustee had continued as Trustee, occurred after the
                  beginning of such 3-month period; and

                         (ii) such receipt of property or reduction of claim
                  occurred within 3 months after such resignation or removal.


   66
                                                                              59



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

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

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

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

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

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

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

                  (c)  For the purposes of this Section only:

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

   67
                                                                              60




                  (2) The term "other indenture securities" means securities
         upon which the Company is an obligor outstanding under any other
         indenture (i) under which the Trustee is also trustee, (ii) which
         contains provisions substantially similar to the provisions of this
         Section, and (iii) under which a default exists at the time of the
         apportionment of the funds and property held in such special account.

                  (3) The term "cash transaction" means any transaction in which
         full payment for goods or securities sold is made within 7 days after
         delivery of the goods or securities in currency or in checks or other
         orders drawn upon banks or bankers and payable upon demand.

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

                  (5)  The term "Company" means any obligor upon the
         Securities.

                  Section 614. Appointment of Authenticating Agent. At any time
when any of the Securities remain Outstanding the Trustee, with the approval of
the Company, may appoint an Authenticating Agent or Agents with respect to one
or more series of Securities which shall be authorized to act on behalf of the
Trustee to authenticate Securities of such series issued upon exchange,
registration of transfer or partial redemption thereof or pursuant to Section
306, and Securities so authenticated shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if authenticated
by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such
   68
                                                                              61



reference shall be deemed to include authentication and delivery on behalf of
the Trustee by an Authenticating Agent and a certificate of authentication
executed on behalf of the Trustee by an Authenticating Agent. Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a corporation organized and doing business under the laws of the United
States of America, any State thereof or the District of Columbia, authorized
under such laws to act as an Authenticating Agent, having a combined capital and
surplus of not less than $50,000,000 and, if other than the Company itself,
subject to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

                  Any corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating Agent.

                  An Authenticating Agent may resign at any time by giving
written notice thereof to the Trustee and, if other than the Company, to the
Company. The Trustee may at any time terminate the agency of an Authenticating
Agent by giving written notice thereof to such Authenticating Agent and, if
other than the Company, to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee, with the approval of the Company, may
appoint a successor Authenticating Agent which shall be acceptable to the
Company and shall mail written notice of such appointment by first-class mail,
   69
                                                                              62





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

                  The Trustee agrees to pay to each Authenticating Agent (other
than an Authenticating Agent appointed at the request of the Company from time
to time) reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 607.

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

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

         of such series as of such date, and

                  (b) at such other times as the Trustee may request in writing,

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

                  (b) If 3 or more Holders of Securities of any series
(hereinafter referred to as "applicants") apply in writing to the Trustee, and
furnish to the Trustee reasonable proof that each such applicant has owned a
Security of such series for a period of at least 6 months preceding the date of
such application, and such application states that the applicants desire to
communicate with other Holders of Securities of such series or with the Holders
of all Securities with respect to their rights under this Indenture or under
such Securities and is accompanied by a copy of the form of proxy or other
communication which such applicants propose to transmit, then the Trustee shall,
   71
                                                                              64



within 5 Business Days after the receipt of such application, at its election,
either

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

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

                  If the Trustee shall elect not to afford such applicants
access to such information, the Trustee shall, upon the written request of such
applicants, mail to each Holder of a Security of such series or to all Security-
holders, as the case may be, whose names and addresses appear in the information
preserved at the time by the Trustee in accordance with Section 702(a), a copy
of the form of proxy or other communication which is specified in such request,
with reasonable promptness after a tender to the Trustee of the material to be
mailed and of payment, or provision for the payment, of the reasonable expenses
of mailing, unless, within 5 days after such tender, the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interests of the Holders
of Securities of such series or all Securityholders, as the case may be, or
would be in violation of applicable law. Such written statement shall specify
the basis of such opinion. If the Commission, after opportunity for a hearing
upon the objections specified in the written statement so filed, shall enter an
order refusing to sustain any of such objections or if, after the entry of an
order sustaining one or more of such objections, the Commission shall find,
after notice and opportunity for hearing, that all the objections so sustained
have been met and shall enter an order so declaring, the Trustee shall mail
copies of such material to all Securityholders of such series or all
Securityholders, as the case may be, with reasonable promptness after the entry
of such order and the renewal of such tender; otherwise the Trustee shall be
relieved of any obligation or duty to such applicants respecting their
application.

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

                  Section 703. Reports by Trustee. (a) The term "reporting date"
as used in this Section means September 1. Within 60 days after the reporting

Securityholders, as their names and addresses appear in the Security Register, a
brief report dated as of such reporting date with respect to any of the
following events which may have occurred during the 12 months preceding the date
of such report (but if no such event has occurred within such period no report

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

                  (4) any change to the amount, interest rate and maturity date
         of all other indebtedness owing by the Company (or by any other obligor

         described in Section 613(b)(2), (3), (4) or (6);

                  (5) any change to the property and funds, if any, physically
         in the possession of the Trustee as such on the date of such report;

                  (6) any additional issue of Securities which the Trustee has
         not previously reported; and

                  (7) any action taken by the Trustee in the performance of its
         duties hereunder which it has not previously reported and which in its
         opinion materially affects the Securities, except action in respect of
         a default, notice of which has been or is to be withheld by the Trustee
         in accordance with Section 602.

                  (b) The Trustee shall transmit by mail to all Securityholders,
as their names and addresses appear in the Security Register, a brief report
with respect to the character and amount of any advances (and if the Trustee
elects so to state, the circumstances surrounding the making thereof) made by
the Trustee (as such) since the date of the last report transmitted pursuant to
Subsection (a) of this Section (or if no such report has yet been so
transmitted, since the date of execution of this instrument) for the
reimbursement of which it claims or may claim a lien or charge, prior to that of
the Securities of any series, on property or funds held or collected by it as
Trustee, and which it has not previously reported pursuant to this Subsection,
except that the Trustee shall not be required (but may elect) to report such
advances if such advances remaining unpaid at any time aggregate 10% or less of
the principal amount of the Securities Outstanding of such series at such time,
such report to be transmitted within 90 days after such time.

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

         reports and of the information, documents and other reports (or copies
         of such portions of any of the foregoing as the Commission may from
         time to time by rules and regulations prescribe) which the Company may
         be required to file with the Commission pursuant to Section 13 or
         Section 15(d) of the Securities Exchange Act of 1934; or, if the
         Company is not required to file information, documents or reports
         pursuant to either of said Sections, then it will file with the Trustee
         and the Commission, in accordance with rules and regulations prescribed
         from time to time by the Commission, such of the supplementary and
         periodic information, documents and reports which may be required

         respect to compliance by the Company with the conditions and covenants
         of this Indenture as may be required from time to time by such rules
         and regulations; and

                  (3) transmit by mail to all Securityholders, as their names
         and addresses appear in the Security Register, within 30 days after the
         filing thereof with the Trustee, such summaries of any information,
         documents and reports required to be filed by the Company pursuant to
         paragraphs (1) and (2) of this Section as may be required by rules and
         regulations prescribed from time to time by the Commission.

                  (1) the corporation formed by such consolidation or into which
         the Company is merged or the Person which acquires by conveyance or
         transfer the properties and assets of the Company substantially as an
         entirety shall be a corporation organized and existing under the laws

                  Section 901. Supplemental Indentures Without Consent of
Securityholders. Without the consent of the Holders of any Securities, the
Company, when authorized by a Board Resolution, and the Trustee, at any time and
from time to time, may enter into one or more indentures supplemental hereto, in
form satisfactory to the Trustee, for any of the following purposes:

                  (1) to evidence the succession of another corporation to the
         Company, and the assumption by any such successor of the covenants of
         the Company herein and in the Securities contained; or

                  (2) to add to the covenants of the Company, or to surrender
         any right or power herein conferred upon the Company, for the benefit
         of the Holders of the Securities of any or all series (and if such
         covenants or the surrender of such right or power are to be for the
         benefit of less than all series of Securities, stating that such
         covenants are expressly being included or such surrenders are expressly
         being made solely for the benefit of one or more specified series); or

                  (3) to cure any ambiguity, to correct or supplement any
         provision herein which may be inconsistent with any other provision
         herein, or to make any other provisions with respect to matters or
         questions arising under this Indenture; or

                  (4) to add to this Indenture such provisions as may be

         referred to in Section 316(a)(2) of the TIA as in effect at the date as
         of which this instrument was executed or any corresponding provision in
         any similar federal statute hereafter enacted; or

                  (5) to establish any form of Security, as provided in Article
         Two, and to provide for the issuance of any series of Securities as
         provided in Article Three and to set forth the terms thereof, and/or to
         add to the rights of the Holders of the Securities of any series; or

                  (6) to evidence and provide for the acceptance of appointment
         by another corporation as a successor Trustee hereunder with respect to
         one or more series of Securities and to add to or change any of the

         well as fully registered form.

                  No supplemental indenture for the purposes identified in
Clauses (2), (3), (5) or (7) above may be entered into if to do so would
adversely affect the interest of the Holders of Securities of any series.

                  Section 902. Supplemental Indentures with Consent of
Securityholders. With the consent of the Holders of not less than a majority in
principal amount of the Outstanding Securities of each series affected by such
supplemental indenture or indentures, by Act of said Holders delivered to the
Company and the Trustee, the Company, when authorized by a Board Resolution, and
the Trustee may enter into an indenture or indentures supplemental hereto for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Indenture or of modifying in any manner the rights
of the Holders of the Securities of each such series under this Indenture;
provided, however, that no such supplemental indenture shall, without the
consent of the Holder of each Outstanding Security affected thereby,

                  (1) change the Maturity of the principal of, or the Stated
         Maturity of any premium on, or any installment of interest on, any
         Security, or reduce the principal amount thereof or the interest or any
         premium thereon, or change the method of computing the amount of
         principal thereof or interest thereon on any date or change any Place
         of Payment where, or the coin or currency in which, any Security or any
         premium or

   78
                                                                              71



         interest thereon is payable, or impair the right to institute suit for
         the enforcement of any such payment on or after the Maturity or the
         Stated Maturity, as the case may be, thereof (or, in the case of
         redemption or repayment, on or after the Redemption Date or the
         Repayment Date, as the case may be); or

                  (2) reduce the percentage in principal amount of the
         Outstanding Securities of any series, the consent of whose Holders is
         required for any such supplemental indenture, or the consent of whose
         Holders is required for any waiver of compliance with certain
         provisions of this Indenture or certain defaults hereunder and their
         consequences, provided for in this Indenture; or

                  (3) modify any of the provisions of this Section, Section 513
         or Section 1007, except to increase any such percentage or to provide
         that certain other provisions of this Indenture cannot be modified or
         waived without the consent of the Holder of each Outstanding Security
         affected thereby.

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

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

                  Section 903. Execution of Supplemental Indentures. In
executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modifications thereby of the trusts
created by this Indenture, the Trustee shall be entitled to receive, and
(subject to Section 601) shall be fully protected in relying upon, an Opinion of
Counsel stating that the execution of such supplemental indenture is authorized
or permitted by this Indenture. The Trustee may, but shall not (except to the
extent required in the case of a supplemental indenture entered into under
Section 901(4) or 901(6)) be obligated to, enter into any such supplemental
   79
                                                                              72



indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

                  Section 904. Effect of Supplemental Indentures. Upon the
execution of any supplemental indenture under this Article, this Indenture shall
be modified in accordance therewith, and such supplemental indenture shall form
a part of this Indenture for all purposes; and every Holder of Securities
theretofore or thereafter authenticated and delivered hereunder shall be bound
thereby to the extent provided therein.

                  Section 905. Conformity with Trust Indenture Act. Every
supplemental indenture executed pursuant to this Article shall conform to the
requirements of the TIA as then in effect.

                  Section 906. Reference in Securities to Supplemental
Indentures. Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall if required by
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so determine,
new Securities so modified as to conform, in the opinion of the Trustee and the
Board of Directors, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities.

                  Section 1001. Payment of Principal, Premium and Interest. With
respect to each series of Securities, the Company will duly and punctually pay
the principal of (and premium, if any) and interest on such Securities in
accordance with their terms and this Indenture, and will duly comply with all
the other terms, agreements and conditions contained in, or made in the
Indenture for the benefit of, the Securities of such series.

                  Section 1002. Maintenance of Office or Agency. The Company
will maintain an office or agency in each Place of Payment where Securities may
be presented or surrendered for payment, where Securities may be surrendered for
transfer or exchange and where notices and demands to or
   80
                                                                              73










upon the Company in respect of the Securities and this Indenture may be served.
The Company will give prompt written notice to the Trustee of the location, and
of any change in the location, of such office or agency. If at any time the
Company shall fail to maintain such 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 principal Corporate Trust Office of the
Trustee, and the Company hereby appoints the Trustee its agent to receive all
such presentations, surrenders, notices and demands.

                  Section 1003. Money for Security Payments to be Held in Trust.
If the Company shall at any time act as its own Paying Agent for any series of
Securities, it will, on or before each due date of the principal of (and
premium, if any) or interest on, any of the Securities of such series, segregate
and hold in trust for the benefit of the Persons entitled thereto a sum
sufficient to pay the principal (and premium, if any) or interest so becoming
due until such sums shall be paid to such Persons or otherwise disposed of as
herein provided, and will promptly notify the Trustee of its action or failure
to act.

                  Whenever the Company shall have one or more Paying Agents for
any series of Securities, it will, on or prior to each due date of the principal
of (and premium, if any) or interest on, any Securities of such series, deposit
with a Paying Agent a sum sufficient to pay the principal (and premium, if any)
or interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal (and premium, if any) or interest, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the
Trustee of its action or failure so to act.

                  The Company will cause each Paying Agent other than the
Trustee for any series of Securities to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will

                  (1) hold all sums held by it for the payment of principal of
         (and premium, if any) or interest on Securities of such series in trust
         for the benefit of the Persons entitled thereto until such sums shall
         be paid to such Persons or otherwise disposed of as herein provided;

   81
                                                                              74




                  (2) give the Trustee notice of any default by the Company (or
         any other obligor upon the Securities of such series) in the making of
         any such payment of principal (and premium, if any) or interest on the
         Securities of such series; and

                  (3) at any time during the continuance of any such default,
         upon the written request of the Trustee, forthwith pay to the Trustee
         all sums so held in trust by such Paying Agent.

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

                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of (and
premium, if any) or interest on any Security of any series and remaining
unclaimed for two years after such principal (and premium, if any) or interest
has become due and payable shall be paid to the Company on Company Request, or
(if then held by the Company) shall be discharged from such trust; and the
Holder of such Security shall thereafter, as an unsecured general creditor, look
only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease. The Trustee or such Paying
Agent, before being required to make any such repayment, may at the expense of
the Company mail to the Holders of the Securities as to which the money to be
repaid was held in trust, as their names and addresses appear in the Security
Register, a notice that such moneys remain unclaimed and that, after a date
specified in the notice, which shall not be less than 30 days from the date on
which the notice was first mailed to the Holders of the Securities as to which
the money to be repaid was held in trust, any unclaimed
   82
                                                                              75



balance of such moneys then remaining will be paid to the Company free of the
trust formerly impressed upon it.

                  The Company initially authorizes the Trustee to act as Paying
Agent for the Securities on its behalf. The Company may at any time and from
time to time authorize one or more Persons to act as Paying Agent in addition to
or in place of the Trustee with respect to any series of Securities issued under
this Indenture.

                  Section 1004. Statement as to Compliance. The Company will
deliver to the Trustee, within 120 days after the end of each fiscal year, a
written statement signed by the principal executive officer, principal financial
officer or principal accounting officer of the Company, stating that

                  (1) a review of the activities of the Company during such year
         and of the Company's performance under this Indenture and under the
         terms of the Securities has been made under his supervision; and

                  (2) to the best of his knowledge, based on such review, the
         Company has complied with all conditions and covenants under this
         Indenture through such year, or, if there has been a default in the
         fulfillment of any such obligation, specifying each such default known
         to him and the nature and status thereof.

                  Section 1005. Corporate Existence. Subject to Article Eight 
the Company will do or cause to be done all things necessary to preserve and
keep in full force and effect its corporate existence.

                  Section 1006. Limitation on Liens. The Company will not, nor
will it permit any Subsidiary to, create, assume, incur or suffer to exist any
Mortgage upon any stock or indebtedness, whether owned on the date of this
Indenture or hereafter acquired, of any Domestic Subsidiary, to secure any Debt
of the Company or any other Person (other than the Securities), without in any
such case making effective provision whereby all of the Securities Outstanding
shall be directly secured equally and ratably with such Debt, excluding,
however, from the operation of the foregoing provisions of this Section 1006 any
Mortgage upon stock or indebtedness of any corporation existing at the time such
corporation becomes a Domestic Subsidiary, or existing upon stock or
indebtedness of a Domestic Subsidiary at the time of acquisition of such stock
or indebtedness, and any extension, renewal or replacement (or successive
extensions,
   83
                                                                              76



renewals or replacements) in whole or in part of any such Mortgage; provided,
however, that the principal amount of Debt secured thereby shall not exceed the
principal amount of Debt so secured at the time of such extension, renewal or
replacement; and provided further, that such Mortgage shall be limited to all or
such part of the stock or indebtedness which secured the Mortgage so extended,
renewed or replaced.

                  Section 1007. Waiver of Certain Covenants. The Company may
omit in respect of any series of Securities, in any particular instance, to
comply with any covenant or condition set forth in Section 1006, if before or
after the time for such compliance the Holders of at least a majority in
principal amount of the Securities at the time Outstanding of such series shall,
by Act of such Securityholders, either waive such compliance in such instance or
generally waive compliance with such covenant or condition, but no such waiver
shall extend to or affect such covenant or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the Company and the duties of the Trustee in respect of any such covenant or
condition shall remain in full force and effect.


                                 ARTICLE ELEVEN

                            Redemption of Securities

                  Section 1101. Applicability of Article. The Company may
reserve the right to redeem and pay before Stated Maturity all or any part of
the Securities of any series, either by optional redemption, sinking or purchase
fund or analogous obligation or otherwise, by provision therefor in the form of
Security for such series established and approved pursuant to Section 202 and on
such terms as are specified in such form or in the Board Resolution or indenture
supplemental hereto with respect to Securities of such series as provided in
Section 301. Redemption of Securities of any series shall be made in accordance
with the terms of such Securities and, to the extent that this Article does not
conflict with such terms, the succeeding Sections of this Article.

                  Section 1102. Election to Redeem; Notice to Trustee. The
election of the Company to redeem any Securities redeemable at the election of
the Company shall be evidenced by, or made pursuant to authority granted by, a
Board Resolution. In case of any redemption at the election
   84
                                                                              77






of the Company of any Securities of any series, the Company shall, at least 60
days prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date and of the principal amount of Securities of such series to be redeemed.

                  In the case of any redemption of Securities (i) prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture, or (ii) pursuant to an election of
the Company which is subject to a condition specified in the terms of such
Securities, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction or condition.

                  Section 1103. Selection by Trustee of Securities to Be
Redeemed. If less than all the Securities of like tenor and terms of any series
are to be redeemed, the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities of such series not previously called for redemption, by
such method as the Trustee shall deem fair and appropriate and which may include
provision for the selection for redemption of portions of the principal of
Securities of such series of a denomination larger than the minimum authorized
denomination for Securities of that series. Unless otherwise provided in the
terms of a particular series of Securities, the portions of the principal of
Securities so selected for partial redemption shall be equal to the minimum
authorized denomination of the Securities of such series, or an integral
multiple thereof, and the principal amount which remains outstanding shall not
be less than the minimum authorized denomination for Securities of such series.
If less than all the Securities of unlike tenor and terms of a series are to be
redeemed, the particular Securities to be redeemed shall be selected by the
Company.

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

                  For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to the redemption of Securities
shall relate, in the case of any Security redeemed or to be redeemed only in
part, to the
   85
                                                                              78



portion of the principal of such Security which has been or is to be redeemed.

                  Section 1104. Notice of Redemption. Notice of redemption shall
be given by first-class mail, postage prepaid, mailed not less than 30 nor more
than 60 days prior to the Redemption Date, to each holder of Securities to be
redeemed, at his address appearing in the Security Register.

                  All notices of redemption shall state:

                  (1) the Redemption Date;

                  (2) the Redemption Price;

                  (3) if less than all Outstanding Securities of any series are
         to be redeemed, the identification (and, in the case of partial
         redemption, the respective principal amounts) of the Securities to be
         redeemed, from the Holder to whom the notice is given;

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

                  (5) the place where such Securities are to be surrendered for
         payment of the Redemption Price, which shall be the office or agency of
         the Company in the Place of Payment; and

                  (6) that the redemption is on account of a sinking or purchase
         fund, or other analogous obligation, if that be the case.

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

                  Section 1105. Deposit of Redemption Price. On or prior to any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 1003) an amount of money sufficient to pay the
Redemption Price of all the Securities which are to be redeemed on that date.
   86
                                                                              79



                  Section 1106. Securities Payable on Redemption Date. Notice of
Redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified and from and after such date (unless the Company shall default
in the payment of the Redemption Price) such Securities shall cease to bear
interest. Upon surrender of such Securities for redemption in accordance with
the notice, such Securities shall be paid by the Company at the Redemption
Price. Installments of interest the Stated Maturity of which is on or prior to
the Redemption Date shall be payable to the Holders of such Securities
registered as such on the relevant Regular Record Dates according to their terms
and the provisions of Section 307.

                  If any Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal shall, until paid, bear
interest from the Redemption Date at the rate borne by the Security, or as
otherwise provided in such Security.

                  Section 1107. Securities Redeemed in Part. Any Security which
is to be redeemed only in part shall be surrendered at the office or agency of
the Company in the Place of Payment with respect to that series (with, if the
Company or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or his attorney duly authorized in writing) and the
Company shall execute and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge, a new Security or Securities of
the same series and Stated Maturity and of like tenor and terms, of any
authorized denomination as requested by such Holder in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.

                  Section 1108. Provisions with Respect to any Sinking Funds.
Unless the form or terms of any series of Securities shall provide otherwise, in
lieu of making all or any part of any mandatory sinking fund payment with
respect to such series of Securities in cash, the Company may at its option (1)
deliver to the Trustee for cancellation any Securities of such series
theretofore acquired by the Company, or (2) receive credit for any Securities of
such series (not previously so credited) acquired by the Company and theretofore
delivered to the Trustee for cancellation or redeemed by the Company other than
through the mandatory sinking fund, and if it does so then (i) Securities so

   87
                                                                              80



delivered or credited shall be credited at the applicable sinking fund
Redemption Price with respect to Securities of such series, and (ii) on or
before the 60th day next preceding each sinking fund Redemption Date with
respect to such series of Securities, the Company will deliver to the Trustee
(A) an Officers' Certificate specifying the portions of such sinking fund
payment to be satisfied by payment of cash and by delivery or credit of
Securities of such series acquired by the Company or so redeemed, and (B) such
Securities so acquired, to the extent not previously surrendered. Such Officers'
Certificate shall also state the basis for such credit and that the Securities
for which the Company elects to receive credit have not been previously so
credited and were not redeemed by the Company through operation of the mandatory
sinking fund, if any, provided with respect to such Securities and shall also
state that no Event of Default with respect to Securities of such series has
occurred and is continuing. All Securities so delivered to the Trustee shall be
cancelled by the Trustee and no Securities shall be authenticated in lieu
thereof.

                  If the sinking fund payment or payments (mandatory or
optional) with respect to any series of Securities made in cash plus any unused
balance of any preceding sinking fund payments with respect to Securities of
such series made in cash shall exceed $50,000 (or a lesser sum if the Company
shall so request), unless otherwise provided by the terms of such series of
Securities, that cash shall be applied by the Trustee on the sinking fund
Redemption Date with respect to Securities of such series next following the
date of such payment to the redemption of Securities of such series at the
applicable sinking fund Redemption Price with respect to Securities of such
series, together with accrued interest, if any, to the date fixed for
redemption, with the effect provided in Section 1106. The Trustee shall select,
in the manner provided in Section 1103, for redemption on such sinking fund
Redemption Date a sufficient principal amount of Securities of such series to
utilize that cash and shall thereupon cause notice of redemption of the
Securities of such series for the sinking fund to be given in the manner
provided in Section 1104 (and with the effect provided in Section 1106) for the
redemption of Securities in part at the option of the Company. Any sinking fund
moneys not so applied or allocated by the Trustee to the redemption of
Securities of such series shall be added to the next cash sinking fund payment
with respect to Securities of such series received by the Trustee and, together
with such payment, shall be applied in accordance with the provisions
   88
                                                                              81



of this Section 1108. Any and all sinking fund moneys with respect to Securities
of any series held by the Trustee at the Maturity of Securities of such series,
and not held for the payment or redemption of particular Securities of such
series, shall be applied by the Trustee, together with other moneys, if
necessary, to be deposited sufficient for the purpose, to the payment of the
principal of the Securities of such series at Maturity.

                  On or before each sinking fund Redemption Date provided with
respect to Securities of any series, the Company shall pay to the Trustee in
cash a sum equal to all accrued interest, if any, to the date fixed for
redemption on Securities to be redeemed on such sinking fund Redemption Date
pursuant to this Section 1108.
   89
                                                                              82
