of any such application or request as to which the furnishing of such documents

certify or give an opinion as to such matters in one or several documents.

                 Any certificate or opinion of an officer of the Company may be

exercise of reasonable care should know, that the certificate or opinion or
representations with respect to the matters upon which his certificate or
opinion is based are erroneous.  Any such certificate or Opinion of Counsel may
be based, insofar as 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 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

   20
                                                                              13

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 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

   21
                                                                              14

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 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

   22
                                                                              15

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.

                 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

   23
                                                                              16

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 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.

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

                 The definitive Securities shall be printed, lithographed or

officers executing such Securities, as evidenced by their execution of such
Securities, subject, with respect to the Securities of any series, to the rules

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

   26
                                                                              19

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

   27
                                                                              20

                 (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.

                                                                              21

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

supplemental indenture prior to the issuance of Securities of each such series,

         stated to be payable, the period or periods within which, and the
         terms and conditions upon which, such election may be made;

         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

         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;

                 (6) if the aggregate principal amount of the 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
         same aggregate principal amount of a different authorized kind or
         different authorized denomination or denominations, or both;

                 (8) the appointment by the Trustee of an Authenticating Agent
         in one or more places other than the location of the office of the

         making any Event of Default set forth herein inapplicable to the

         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); and

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

all upon such terms as may be determined in or pursuant to a Board Resolution
or in or pursuant to a supplemental

   31
                                                                              24

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

   32
                                                                              25

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 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;

               (4) the Indenture is qualified under the Trust Indenture Act; and

   33
                                                                              26


                 (5) 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, 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 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

   34
                                                                              27

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 or registers (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.

                 Subject to Section 204, at the option of the Holder,
Securities of any series may be exchanged for other

   35
                                                                              28

Securities of such series of any authorized denominations, of a like aggregate
principal amount and Stated Maturity, 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.

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

                                                                              29

                 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.

                 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.

                                                                              30


                 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 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

   38
                                                                              31

         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.

                 Section 309.  Cancellation.  All Securities surrendered for
payment, redemption, transfer, conversion or exchange or credit against a
sinking fund shall, if surren-

   39
                                                                              32

dered 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 destroy all cancelled
Securities and deliver a certificate of such destruction 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 or supplemental 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,

   40
                                                                              33

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 or, 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
                 authenticated and delivered (other than (i) Securities of such
                 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
                 theretofore been deposited in trust or segregated and held in
                 trust by the Company and thereafter repaid to the Company or
                 discharged from such trust, as provided in Section 1003) have
                 been delivered to the Trustee cancelled or for cancellation;
                 or

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

                          one year under arrangements satisfactory to the
                          Trustee for the giving of

   41
                                                                              34

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

and the Company, in the case of (i), (ii) or (iii) above, has deposited or
caused to be deposited with the Trustee as trust funds in trust for 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 deposited
with the Trustee pursuant to Section 401 or Section 403 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

acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal (and premium, if any) and interest for whose
payment such money has been deposited with the Trustee; but such money need not
be segregated from other funds except to the extent required by law.

                 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

Securities of any such series at the time outstanding, and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging

                          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

                          issued the currency in which such Securities are
                          denominated as will, together with the income to
                          accrue thereon without consideration of any
                          reinvestment thereof, be sufficient 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

                                                                              36

                          (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.

                 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, 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.

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

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

         this purpose, and continuance of such default or breach for a period
         of 90 days after there has been given, by registered or certified

                 (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

   46
                                                                              39

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 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

   47
                                                                              40


                          (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 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

   48
                                                                              41

         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 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,

   49
                                                                              42

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 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

   50
                                                                              43

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 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

   51
                                                                              44

         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 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

   52
                                                                              45

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
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

   53
                                                                              46

                 (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 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

   54
                                                                              47

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.

                 Section 516.  Record Dates for Action by Holders.  If the
Company shall solicit from the Holders of Securities of any series any action
(including the making of any demand or request, the giving of any direction,
notice, consent or waiver or the taking of any other action), the Company may,
at its option, by Board Resolution, fix in advance a record date for the
determination of Holders of Securities entitled to take such action, but the
Company shall have no obligation to do so.  Any such record date shall be fixed
at the Company's discretion.  If such a record date is fixed, such action may
be sought or given before or after the record date, but only the Holders of
Securities of record at the close of business on such record date shall be
deemed to be Holders of Securities for the purpose of determining whether
Holders of the requisite proportion of Securities of such series Outstanding
have authorized or agreed or consented to such action, and for that purpose the
Securities of such series Outstanding shall be computed as of such record date.

   55
                                                                              48

                                  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 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;

   56
                                                                              49

                 (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 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

both would become, an Event of Default with respect to Securities of such
series.

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,

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

   59
                                                                              52


                 (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

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

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

   61
                                                                              54

                 (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.

                 (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

   62
                                                                              55

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 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

   63
                                                                              56

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 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

   64
                                                                              57

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, 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.

   65
                                                                              58

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 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

   66
                                                                              59

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 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

                                                                              60

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.

                 (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,

                                                                              61

                 (4) an indebtedness created as a result of services rendered
         or premises rented; or an indebtedness created as a result of goods or

         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.

                 (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

         or merchandise and which is secured by documents

   69
                                                                              62

         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 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

   70
                                                                              63

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,
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 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.

   71
                                                                              64

                 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 Securityholders.  The Company will furnish or cause to be furnished to the
Trustee

                 (a) semi-annually, not more than 15 days after each Regular
         Record Date, in each year in such form as the Trustee may reasonably
         require, a list of the names and addresses of the Holders of
         Securities of such series as of such date, and

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

excluding from any such list names and addresses received by the Trustee in its
capacity as Security Registrar.

                                                                              65

                 Section 702.  Preservation of Information; Communications to
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, 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
Securityholders, 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

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).

         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;

         a

         of the United States of America or any State or the District of
         Columbia, and shall expressly assume, by an indenture supplemental
         hereto, executed and delivered to the Trustee, in form satisfactory to
         the Trustee, the due and punctual payment of the principal of (and
         premium, if any) and interest on all the Securities and the
         performance of every covenant of this Indenture on the part of the
         Company to be performed or observed;

                                                                              70


                 (2) immediately after giving effect to such transaction, no
         Event of Default, and no event which, after notice or lapse of time,
         or both, would become an Event of Default, shall have happened and be
         continuing; and

                 (3) the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel each stating that such
         consolidation, merger, conveyance or transfer and such supplemental
         indenture comply with this Article and that all conditions precedent
         herein provided for relating to such transaction have been complied
         with.

                 Section 802.  Successor Corporation Substituted.  Upon any
consolidation or merger, or any conveyance or transfer of the properties and
assets of the Company substantially as an entirety in accordance with Section
801, the successor corporation formed by such consolidation or into which the
Company is merged or to which such conveyance or transfer is made shall succeed
to, and be substituted for, and may exercise every right and power of, the
Company under this Indenture with the same effect as if such successor
corporation had been named as the Company herein.  In the event of any such
conveyance or transfer, the Company as the predecessor corporation may be
dissolved, wound up or liquidated at any time thereafter.

                            Supplemental Indentures

                 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

   78
                                                                              71

         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
         expressly permitted by the TIA, excluding, however, the provisions
         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
         provisions of this Indenture as shall be necessary to provide for or
         facilitate the administration of the trusts hereunder by more than one
         Trustee, pursuant to Section 611; or

                 (7) to add any additional Events of Default in respect of the
         Securities of any or all series (and if such additional Events of
         Default are to be in respect of less than all series of Securities,
         stating that such Events of Default are expressly being included
         solely for the benefit of one or more specified series); or

   79
                                                                              72

                 (8) to provide for the issuance of Securities in coupon as 
         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 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

   80
                                                                              73

                 (3) modify any of the provisions of this Section, Section 513
         or Section 1008, 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 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

   81
                                                                              74

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.


                                  ARTICLE TEN

                                   Covenants

                 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 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.

   82
                                                                              75

                 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;

                 (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.

   83
                                                                              76

                 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 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.

   84
                                                                              77

                 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 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.  (a)  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
Subsection (a) 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, 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.

   85
                                                                              78

                 (b)  The Company will not, nor will it permit any Restricted
Subsidiary to, create, assume, incur or suffer to exist any Mortgage upon any
Principal Property, whether owned or leased on the date of this Indenture or
hereafter acquired, 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 Subsection (b):

                 (i) any Mortgage upon property owned or leased by any
         corporation existing at the time such corporation becomes a Restricted
         Subsidiary;

                 (ii) any Mortgage upon property existing at the time of
         acquisition thereof or to secure the payment of all or any part of the
         purchase price thereof or to secure any Debt incurred prior to, at the
         time of or within 180 days after the acquisition of such property for
         the purpose of financing all or any part of the purchase price
         thereof;

                 (iii) any Mortgage upon property to secure all or any part of
         the cost of exploration, drilling, development, construction,
         alteration, repair or improvement of all or any part of such property,
         or Debt incurred prior to, at the time of or within 180 days after the
         completion of such exploration, drilling, development, construction,
         alteration, repair or improvement for the purpose of financing all or
         any part of such cost;

                 (iv) any Mortgage securing Debt of a Restricted Subsidiary
         owing to the Company or to another Restricted Subsidiary;

                 (v) any Mortgage existing at the date of this Indenture; and

                 (vi) any extension, renewal or replacement (or successive
         extensions, renewals or replacements) in whole or in part of any
         Mortgage referred to in the foregoing clauses (i) to (v), inclusive;
         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

   86
                                                                              79

         shall be limited to all or such part of the property which secured the
         Mortgage so extended, renewed or replaced (plus improvements on such
         property).

Notwithstanding the foregoing provisions of this Subsection (b), the Company
may, and may permit any Restricted Subsidiary to, create, assume, incur or
suffer to exist any Mortgage upon any Principal Property which is not excepted
by clauses (i) through (vi) above without equally and ratably securing the
Securities, provided that the aggregate amount of all Debt then outstanding
secured by such Mortgage and all similar Mortgages does not exceed 10% of the
total consolidated stockholders' equity of the Company as shown on the audited
consolidated balance sheet contained in the latest annual report to
stockholders of the Company.  For the purpose of this Subsection (b), the
following types of transactions shall not be deemed to create a Mortgage to
secure any Debt:

                 (i) the sale or other transfer of (A) any oil or gas or
         minerals in place for a period of time until, or in an amount such
         that, the purchaser will realize therefrom a specified amount of money
         (however determined) or a specified amount of such oil or gas or
         minerals, or (B) any other interest in property of the character
         commonly referred to as a "production payment"; and

                 (ii) any Mortgage in favor of the United States of America or
         any State thereof, or any other country, or any political subdivision
         of any of the foregoing, to secure partial, progress, advance or other
         payments pursuant to the provisions of any contract or statute, or any
         Mortgage upon property of the Company or a Restricted Subsidiary
         intended to be used primarily for the purpose of or in connection with
         air or water pollution control, provided that no such Mortgage shall
         extend to any other property of the Company or any Restricted
         Subsidiary.

                 Section 1007.  Limitation on Transfers of Principal Properties
to Unrestricted Subsidiaries.  The Company will not, nor will it permit any
Restricted Subsidiary to, sell, transfer or otherwise dispose of any Principal
Property to any Unrestricted Subsidiary other than for cash or other
consideration which, in the opinion of the Board of Directors, constitutes fair
value for such Principal Property.

   87
                                                                              80


                 Section 1008.  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 Sections 1006 and 1007, 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 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 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.

   88
                                                                              81

                 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 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

   89
                                                                              82

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.

                 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

   90
                                                                              83

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, 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, and if it does so then
(i) Securities so 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

   91
                                                                              84

sinking fund payment to be satisfied by payment of cash and by delivery or
credit of Securities of such series acquired by the Company, and (B) such
Securities, 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 acquired by the Company through operation of the
mandatory sinking fund, if any, provided with respect to such Securities and
are not required to be delivered to the Trustee pursuant to Section 309 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 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

   92
                                                                              85

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.
