          SECTION 1.04.  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 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 6.01)  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

 
                                                                              17

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.  Such record date shall be the later
of 10 days prior to the first solicitation of such action or the date of the
most recent list of Holders furnished to the Trustee pursuant to Section 7.01.
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 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, and that no such authorization, agreement
or consent may be amended, withdrawn or revoked once given by a Holder, unless
the Company shall provide for such amendment, withdrawal or revocation in
conjunction with such solicitation of authorizations, agreements or consents or
unless and to the extent required by applicable law.

          (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 registration of 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

 
                                                                              18

such Security.

          SECTION 1.05.  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:

          (a) 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, Attention
     of Corporate Trust Department; or

          (b) the Company by the Trustee or by any  securityholder shall be
     sufficient for every purpose hereunder (except as provided in Section
     5.01(d) 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,
     Attention of Treasurer, or at any other address previously furnished in
     writing to the Trustee by the Company.

          SECTION 1.06.  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 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

 
                                                                              19

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 1.07.  Conflict with Trust Indenture Act.  If and to the
                         ----------------------------------               
extent that any provision hereof limits, qualifies or conflicts with the duties
imposed by, or with another provision (an "incorporated provision") included in
this Indenture by operation of, any of Sections 3.10 to 3.18, inclusive, of the
Trust Indenture Act, such imposed duties or incorporated provision shall
control.

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 1.11.  Benefits of Indenture.  Nothing in  this Indenture or
                         ----------------------

          SECTION 2.04.  Securities Issuable in the Form of a Global Security.
                         ----------------------------------------------------- 
(a)  If the Company shall establish pursuant to Sections 2.02 and 3.01 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 3.03 and the Company Order
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
Order, (ii) shall be registered in the name of the Depository for such Global
Security or Securities or its nominee, (iii) shall be delivered by the Trustee
or its agent to the Depository or pursuant to the Depository's instruction and
(iv) shall bear a legend substantially to the following effect:

     "Unless this certificate is presented by an authorized representative of
     the Depository to Issuer or its agent for registration of transfer,
     exchange, or payment, and any certificate issued is registered in the name
     of the nominee of the Depository or in such other name as is requested by
     an authorized representative of the Depository (and any payment is made to
     the nominee of the Depository or to such other entity as is requested

 
                                                                              23

     by an authorized representative of the Depository), ANY TRANSFER, PLEDGE,
     OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
     inasmuch as the registered owner hereof, the nominee of the Depository, has
     an interest herein."

          (b)  Notwithstanding any other provision of this Section 2.04 or of
Section 3.05, 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 Depository for such Global Security, or to the
Depository, or a successor Depository for such Global Security selected or
approved by the Company, or to a nominee of such successor Depository.

          (c)  (i)  If at any time the Depository for a Global Security notifies
the Company that it is unwilling or unable to continue as Depository for such
Global Security or if at any time the Depository for the Securities for such
series shall no longer be eligible or in good standing under the Securities
Exchange Act of 1934, as amended, or other applicable statute or regulation, the
Company shall appoint a successor Depository with respect to such Global
Security. If a successor Depository 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

 
                                                                              24

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.

          (iii)  If specified by the Company pursuant to  Sections 2.02 and 3.01
with respect to Securities issued or issuable in the form of a Global Security,
the Depository 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 Depository.  Thereupon the Company shall execute, and the
Trustee or its agent shall authenticate and deliver, without service charge, (A)
to each Person specified by such Depository 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 as specified by such Depository in the
Global Security; and (B) to such Depository 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 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
canceled 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 Depository 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 at its
Corporate Trust Office such Securities to the Persons in whose names such
Securities are so registered.

          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 for the method by which such terms or provisions shall be determined.

          SECTION 3.02.  Denominations.  The Securities of each series shall be

                                                                              29

          SECTION 3.03.  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 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 1.02, and
the Board Resolution and any certificate relating to the issuance of the series
of Securities required to be furnished pursuant to Section 2.02, an Opinion of
Counsel stating that:

          (a) 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;

          (b) the form and terms of such Securities have been established in
     conformity with the provisions of this Indenture;

          (c) 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

 
                                                                              30

     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;

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

          (e) 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

 
                                                                              31

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.  Notwithstanding the foregoing, if any
Security shall have been authenticated and delivered hereunder but never issued
and sold by the Company, and the Company shall deliver such Security to the
Trustee for cancellation as provided in Section 3.09, for all purposes of this
Indenture such Security shall be deemed never to have been authenticated and
delivered hereunder and shall never be entitled to the benefits of this
Indenture.

          SECTION 3.04.  Temporary Securities.  Pending the preparation of
                         ---------------------                            
definitive Securities of any series, the Company may execute, and, upon receipt
of the documents required by Section 3.03, 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 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 3.05.  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

 
                                                                              32

regulations as it may prescribe, the Company shall provide for the registration
of Securities, or of Securities of a particular series, and of 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
10.02.  There shall be only one Security Register per series of Securities.

          Subject to Section 2.04, upon surrender for  registration of transfer
of any Security of any series at  the office or agency of the Company maintained
for such purpose 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 2.04, at the option of the  Holder, Securities of
any series may be exchanged for other Securities of such series of any
authorized denominations, of a like aggregate principal amount and Stated
Maturity and like tenor and terms, upon surrender of the Securities to be
exchanged at such office or agency.  Whenever any Securities are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Securityholder making the exchange is entitled
to receive.

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

          Every Security presented or surrendered for  registration of 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 Trustee duly executed, by the Holder thereof
or his attorney duly authorized in writing.

 
                                                                              33

          Unless otherwise provided in the Security to be  registered for
transfer or exchanged, no service charge shall be made on any Securityholder for
any registration of 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 registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 3.04, 9.06 or 11.07 not involving any transfer.

          The Company shall not be required (a) to issue,  register the transfer
of 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
11.03 and ending at the close of business on the date of such mailing or (b) to
register the transfer of 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.

          SECTION 3.06.  Mutilated, Destroyed, Lost and Stolen Securities.  If
                         -------------------------------------------------    
(a) 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(b) 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 written 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

 
                                                                              34

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.

          SECTION 3.07.  Payment of Interest; Interest Rights Preserved.  Unless
                         -----------------------------------------------        
otherwise provided with respect to such security pursuant to Section 3.01,
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 (a) or
clause (b) below:

          (a) 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

 
                                                                              35

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
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 (b).

          (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.

 
                                                                              36

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

          SECTION 3.08.  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 as the owner of such Security for the purpose of
receiving payment of principal of (and premium, if any), and (subject to Section
3.07) interest on, such Security and for all other purposes whatsoever, whether
or not such Security be overdue, and neither the Company, the Trustee nor any
agent of the Company or the Trustee shall be affected by notice to the contrary.

          None of the Company, the Trustee, 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 in a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

          SECTION 3.09.  Cancellation.  All Securities surrendered for payment,
                         -------------                                         
redemption, conversion, registration of transfer, or exchange or credit against
a sinking fund shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee and, if not already cancelled, shall be promptly
cancelled by it.  The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and all Securities
so delivered shall be promptly cancelled by the Trustee.  No Security shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section, except as expressly permitted by this Indenture.  The Trustee
shall dispose of all cancelled Securities in accordance with its standard
procedures and deliver a certificate of such disposition to the Company.

          SECTION 3.10.  Computation of Interest.  Unless otherwise provided as
                         ------------------------                              
contemplated in Section 3.01, interest on the Securities shall be calculated on
the basis of a 360-day year of twelve 30-day months.

 
                                                                              37

          SECTION 3.11.  Delayed Issuance of 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 Order otherwise required pursuant to
Sections 1.02, 2.02, 3.01 and 3.03 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 or other certificates delivered pursuant to Sections 1.02 and 2.02
shall be true and correct as if made on such date.

          A Company Order, Officers', Certificate or Board Resolution or
supplemental indenture 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 in the aggregate principal
amount, if any, established for such series pursuant to such procedures
acceptable to the Trustee as may be specified from time to time by Company Order
upon the telephonic, electronic or written order of Persons designated in such
Company Order, Officers' Certificate, supplemental indenture or Board Resolution
(any such telephonic or electronic instructions to be promptly confirmed in
writing by such Persons) and that such Persons are authorized to determine,
consistent with such Company Order, Officers' Certificate, supplemental
indenture or Board Resolution, such terms and conditions of said Securities as
are specified in such Company Order, Officers' Certificate, supplemental
indenture or Board Resolution.

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

          payment money in the Required Currency has theretofore been deposited
          in trust or segregated and held in trust by the Company and thereafter

          cancellation; or

              (ii) all such Securities of that series not theretofore delivered
          to the Trustee canceled or for cancellation:

          arrangements satisfactory to the Trustee for the giving of notice of
          redemption by the Trustee in the name, and at the expense, of the
          Company,

          and the Company, in the case of (a), (B) or (C) above, has irrevocably

          by Article XIII) with the Trustee as trust funds in trust for the
          purpose an amount in the Required Currency sufficient to pay and
          discharge the entire indebtedness on such Securities not theretofore

          Stated Maturity or Redemption Date, as the case may be;

          (b) 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

          (c) 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 6.07 shall survive and the obligations of
the Company and the Trustee under Sections 3.05, 3.06, 4.02, 10.02 and 10.03
shall survive.

          SECTION 4.02.  Application of Trust Money.  Subject to the provisions
                         ---------------------------

after the applicable conditions set forth below have been satisfied or (b) the
Company shall cease to be under any obligation to comply with any term,
provision or condition set forth in Sections 10.05 and 10.07 and Article Eight
(and any other Sections or covenants applicable to such Securities that are
determined pursuant to Section 3.01 to be subject to this provision), and clause
(d) of Section 5.01 of this Indenture (and any other Events of Default
applicable to such Securities that are determined pursuant to Section 3.01 to be
subject to this provision) shall be deemed not to be an Event of Default, with
respect to any series of Securities at any time after the applicable conditions
set forth below have been satisfied:

     deposit is not prohibited by Article Thirteen) irrevocably with the Trustee
     as trust funds in trust, specifically pledged as security for, and
     dedicated solely to, the benefit of the Holders of the Securities of such
     series (A) money in an amount, (B) the equivalent in securities of the
     government which issued the currency in which the Securities are
     denominated or government agencies backed by the full faith and credit of
     such government which through the payment of interest and principal in
     respect thereof in accordance with their terms will provide, not later than
     one day before the due date of any payment, money in an amount or (C) a
     combination of (A) and (B), sufficient, in the opinion (with respect to (B)
     and (C)) of a nationally recognized firm of independent public accountants
     expressed in a written certification thereof delivered to the Trustee, to
     pay and discharge each installment of principal (including mandatory
     sinking fund payments) and any premium of, interest on and any repurchase
     or redemption obligations with respect to the outstanding Securities of
     such series on the dates such installments of interest or principal or
     repurchase or redemption obligations are due (before

     such a deposit, if the Securities of such series are then redeemable or may
     be redeemed in the future pursuant to the terms thereof, in either case at
     the option of the Company, the Company may give to the Trustee, in
     accordance with Section 11.02, a notice of its election to redeem all of
     the Securities of such series at a future date in accordance with Article
     Eleven);

          (ii) no Event of Default or event (including such deposit) which with
     notice or lapse of time would become an Event of Default with respect to
     the Securities of such series shall have occurred and be continuing on the
     date of such deposit;

          (iii) the Company shall have delivered to the Trustee (A) an Opinion
     of Counsel to the effect that Holders of the Securities of such series will
     not recognize income, gain or loss for Federal income tax purposes as a
     result of the Company's exercise of its option under this Section 4.03 and
     will be subject to Federal income tax on the same amount and in the same
     manner and at the same times as would have been the case if such option had
     not been exercised, and, in the case of Securities being Discharged,
     accompanied by a ruling to that effect from the Internal Revenue Service,
     unless, as set forth in such Opinion of Counsel, there has been a change in
     the applicable federal income tax law since the date of this Indenture such
     that a ruling from the Internal Revenue Service is no longer required and
     (B) an Opinion of Counsel, subject to such qualifications, exceptions,
     assumptions and limitations as are reasonably deemed necessary by such
     counsel and are reasonably satisfactory to counsel for the Trustee, to the
     effect that the trust resulting from the deposit referred to in paragraph
     (i) above does not violate the Investment Company Act of 1940; and

          (iv) the Company shall have delivered to the Trustee an Officers'
     Certificate stating that the deposit referred to in paragraph (i) above was
     not made by the Company with the intent of preferring the Holders over
     other creditors of the Company or with the intent of defeating, hindering,
     delaying or defrauding creditors of the Company or others.

 
                                                                              42

          "Discharged" means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by, and obligations under, the
Securities of such series and to have satisfied all the obligations under this
Indenture relating to the Securities of such series (and the Trustee, upon
receipt of a Company Request and at the expense of the Company, shall execute
proper instruments acknowledging the same), except (a) the rights of Holders of
Securities to receive, from the trust fund described in paragraph (i) above,
payment of the principal and any premium of and any interest on such Securities
when such payments are due; (B) the Company's obligations with respect to such
Securities under Sections 3.05, 3.06, 4.02, 6.07, 10.02 and 10.03; (c) the
Company's right of redemption, if any, with respect to any Securities of such
series pursuant to Article XI, in which case the Company may redeem the
Securities of such series in accordance with Article XI by complying with such
Article and depositing with the Trustee, in accordance with Section 11.05, an
amount of money sufficient, together with all amounts held in trust pursuant to
Section 4.02 with respect to Securities of such series, to pay the Redemption
Price of all the Securities of such series to be so redeemed; and (d) the
rights, powers, trusts, duties and immunities of the Trustee hereunder.

unable to apply any money or securities in accordance with Section 4.02 of this
Indenture by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to Section 4.01 or 4.03 of this Indenture, as the
case may be, until such time as the Trustee or Paying Agent is permitted to
apply all such money or securities in accordance with Section 4.02 of this
Indenture; provided that, if the Company has made any payment of principal of or
           --------

Company shall be subrogated to the rights of the Holders of such Securities to
receive such payment from the money or securities held by the Trustee or paying
Agent.

Indenture respecting subordination  of the Securities; provided, however, that

an Event of Default described in paragraph (a), (b), (c), (d) or (g) (if the
Event of Default under paragraph (d) or (g) is with respect to less than all
series of Securities then Outstanding) of Section 5.01 occurs and is continuing
with respect to any series, then and in each and every such case, unless the
principal of all the Securities of such series shall have already become due and
payable, either the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Securities of such series then Outstanding hereunder
(each such series acting as a separate class), by notice in writing to the
Company (and to the Trustee if given by Holders), may declare the principal
amount (or, if the Securities of such series are Original Issue Discount
Securities, such portion of the principal amount as may be specified in the
terms of that series) of all the Securities of such series 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,

contrary notwithstanding.  If an Event of Default described in paragraph (d) or
(g) (if the Event of Default under paragraph (d) or (g) is with respect to all
series of Securities then Outstanding), of Section 5.01 occurs and is
continuing, then and in each and every such case; unless the principal of all

and shall be immediately due and payable, anything in this Indenture or in the
Securities contained to the contrary notwithstanding.

 
                                                                             46

If an Event of Default of the type set forth in clause (e) or clause (f) of
Section 5.01 occurs and is continuing, the principal of and any interest on the
Securities then Outstanding shall become immediately due and payable.

          At any time after such a declaration of acceleration has been made
with respect to the Securities of any or all series, as the case may be, 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

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

               (i) all overdue installments of interest on the Securities of
          such series;

               (ii) 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;

               (iii) 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

               (iv) 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 6.07; and

          (b) 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 5.13.

 
                                                                              47

consequent thereon.

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

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

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

and any such default continues for any period of grace provided with respect to
the Securities of such series, the Company will, upon demand of the Trustee, pay
to it, for the benefit of the Holder of any such Security (or the Holders of any
such series in the case of Clause (c) 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 (c) 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 (c) 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 6.07.

          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

 
                                                                              48

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

          (a) to file and prove a claim for the whole amount of principal (or
     portion thereof determined pursuant to Section 3.01(16) to be provable in
     bankruptcy) (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 6.07) and of the
     Securityholders allowed in such judicial proceeding; and

          (b) 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 6.07.

          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 of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof, or to authorize the Trustee to
vote in respect of the claim of any Securityholder in any such proceeding.

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 and any other amounts due the Trustee under Section 6.07, be for the
ratable benefit of the Holders of the Securities of the series in respect of
which such judgment has been recovered.

          SECTION 5.06.  Application of Money Collected.  Any money collected by
                         -------------------------------

series and the notation thereon of the payment if only partially paid and upon

or for any other remedy hereunder, unless

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

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

          (c) such Holder or Holders have offered to the Trustee reasonable

          (e) 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

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.

                         -----------------------------------                   
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

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 give hereunder or now or hereafter existing at law

hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

          SECTION 5.11.  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.

 
                                                                              52

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:

          (a) 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

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

          SECTION 5.13.  Waiver of Past Defaults.  The Holders of not less than

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:

          (a) 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

          (b) in respect of a covenant or provision hereof which under Article
     IX 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.

 
                                                                              53

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 and Securityholder for the enforcement of the payment
of the principal of (or premium, if any) or interest on any Security on or after
the respective Stated Maturities expressed in such Security (or, in the case of
redemption or repayment, on or after the Redemption Date or Repayment Date, as
the case may be).

                         ---------------------------------             
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.

 
                                                                              54

          (i) 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

          (ii) 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 wilful misconduct, except that:

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

          (ii) 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;

 
                                                                              55

          (iii) 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

          (iv) 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 6.02.  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 5.01(4) with respect to Securities of such series no such notice to
Securityholders of such series shall be given until at least 90 days after the
occurrence thereof.  For the purpose of this Section, the term "default", with
respect to Securities

 
                                                                              56

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

     evidence be herein specifically prescribed) may, in the absence of bad
     faith on its part, rely upon an Officers' Certificate;

          (d) the Trustee may consult with counsel and the written advice of

     indemnity against the costs, expenses and liabilities which might be
     incurred by it in compliance with such request or direction;

          (f) the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,

     opinion, report, notice, request, direction, consent, order, bond,
     debenture or other paper or document, but the Trustee, in its discretion,
     may make such further inquiry or investigation into such facts or matters
     as it may see fit, and, if the Trustee shall determine to make such further
     inquiry or investigation, it shall be entitled to examine the books,

     the discretion or rights or powers conferred upon it by this Indenture.

          SECTION 6.04.  Not Responsible for Recitals or Issuance of Securities.
                         -------------------------------------------------------
The recitals contained herein and in the Securities, except the certificates of
authentication, shall be taken as the statements of the Company, and the Trustee
assumes no responsibility for their correctness.  The Trustee makes no

Securities.  The Trustee shall not be accountable for the use or application by
the Company of Securities or the proceeds thereof.

          SECTION 6.05.  May Hold Securities.  The Trustee, any Authenticating
                         --------------------                                 
Agent, any Paying Agent, the Security

 
                                                                              58

Registrar, any Conversion Agent or any other agent of the Company, in its
individual or any other capacity, may become the owner or pledgee of Securities
and, subject to Sections 6.08 and 6.13, may otherwise deal with the Company with
the same rights it would have if it were not Trustee, Authenticating Agent,
Paying Agent, Security Registrar, Conversion Agent or such other agent.

          SECTION 6.06.  Money Held in Trust.  Subject to the provisions of
                         --------------------                              
Section 10.03 hereof, all moneys in any currency or currency received by the
Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received, but need not be segregated from other

liability for interest on any money received by it hereunder except as otherwise
agreed in writing with the Company.

          SECTION 6.07.  Compensation and Reimbursement.  The Company agrees:
                         -------------------------------                     

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

          (b) 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

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

          As security for the performance of the obligations of the Company
under this Section the Trustee shall have a

 
                                                                              59

lien prior to the Securities upon all property and funds held or collected by
the Trustee as such, except funds held in trust for the payment of principal of
(and premium, if any) or interest on particular Securities.

          When the Trustee incur expenses or renders services in connection with
an Event of Default specified in Section 5.01(e) or (f), the expenses and the
compensation for the services are intended to constitute expenses of
administration under any bankruptcy law.

          The Company's obligations under this Section 6.07 and any lien arising
hereunder shall survive the resignation or removal of any Trustee, the discharge
of the Company's obligations pursuant to Article IV of this Indenture and/or the
termination of this Indenture.

          SECTION 6.08.  Disqualification; Conflicting Interests.  The Trustee
                         ----------------------------------------             
for the Securities of any series issued hereunder shall be subject to the
provisions of Section 3.10(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 3.10(b) of the Trust Indenture Act with respect
to the Securities of any series, there shall be excluded this Indenture with
respect to Securities of any particular series of Securities other than that
series.  Nothing herein shall prevent the Trustee from filing with the
Commission the application referred to in the second to last paragraph of
Section 3.10(b) of the Trust Indenture Act.

          SECTION 6.09.  Corporate Trustee Required; Eligibility.  There shall
                         ----------------------------------------             
at all times be a Trustee hereunder with respect to each series of Securities,
which shall be either:

          (a) 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 and subject to supervision or examination
     by Federal or State authority; or

          (b) a corporation or other Person organized and doing business under
     the laws of a foreign government that is permitted to act as Trustee
     pursuant to a rule, regulation or order of the Commission, authorized under
     such laws to exercise corporate trust powers, and subject to supervision or
     examination by authority of

 
                                                                              60

     such foreign government or a political subdivision thereof substantially
     equivalent to supervision or examination applicable to United States
     institutional trustees,

in either case having a combined capital and surplus of at least $50 million.
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.
Neither the Company nor any Person directly or indirectly controlling,
controlled by, or under common control with the Company shall serve as trustee
for the Securities of any series issued hereunder.  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 specified in Section 6.10.

          SECTION 6.10.  Resignation and Removal; Appointment of Successor.  (a)
                         --------------------------------------------------
No resignation or removal of the Trustee and no appointment of a successor
Trustee pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee under Section 6.11.

          (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.

 
                                                                              61

          (d)  If at any time:

          (i) the Trustee shall fail to comply with Section 3.10(b) of the Trust
     Indenture Act pursuant to Section 6.08 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 six months, unless the Trustee's duty to resign is stayed in
     accordance with the provisions of Section 3.10(b) of the Trust Indenture
     Act; or

          (ii) the Trustee shall cease to be eligible under Section 6.09 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

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

          (iv) 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, (A) the Company by a Board Resolution may remove the
Trustee, with respect to the series, or in the case of Clause (iv), with respect
to all series, or (B) subject to Section 5.14, any Securityholder who has been a
bona fide Holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee with respect to the series, or, in the case of Clause (iv),
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

 
                                                                              62

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, subject to Section
5.14, any Securityholder who has been a bona fide Holder of a Security of that
series for at least six 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 6.11.  Acceptance of Appointment by Successor.  Every
                         ---------------------------------------       
successor Trustee appointed hereunder shall execute, acknowledge and deliver to
the Company and to the predecessor Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the predecessor Trustee
shall become effective with respect to any series as to which it is resigning or
being removed as Trustee, and such successor Trustee, without any further act,
deed or conveyance, shall become vested with all the rights, powers, trusts and
duties of the predecessor Trustee with respect to any such series; but, on
request of the Company or the successor Trustee, such predecessor Trustee shall,
upon payment of its reasonable charges, if any, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and
trusts of the predecessor Trustee, and shall duly assign, transfer and deliver
to such successor Trustee all property and money held by such predecessor
Trustee hereunder with respect to all or any such series, subject nevertheless
to its lien, if any, provided for in Section 6.07.  Upon request of any such
successor Trustee, the Company shall execute any and all

 
                                                                              63

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

 
                                                                              64

          SECTION 6.13.  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 three 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):

          (i) an amount equal to any and all reduction in the amount due and
     owing upon any claim as such creditor in respect of principal or interest,
     effected after the beginning of such three-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 (ii) 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

          (ii) 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 three-month
     period, or an amount equal to the proceeds of any such property, if
     disposed of, subject, however, to the rights, if any, of the Company and
     its other creditors in such property or such proceeds.

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

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

 
                                                                              65

          (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 three-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
     three-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 three months; or

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

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

 
                                                                              66

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 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 three-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 three-month period, it
shall be subject to the provisions of

 
                                                                              67

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 three-month period; and

          (ii) such receipt of property or reduction of claim occurred within
     three 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

          (i) 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;

          (ii) 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;

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

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

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

 
                                                                              68

          (vi) 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:

          (i)  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.

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

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

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

          (v)  The term "Company" means any obligor upon the securities.

 
                                                                              69

          SECTION 6.14.  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 original issuance,
exchange, registration of transfer or partial redemption thereof or pursuant to
Section 3.06, 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 Million and, if other than the Company itself, subject to supervision or
examination by Federal or State authority.  If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section, the combined capital and surplus of such Authenticating Agent
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published.  If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section,
such Authenticating Agent shall resign immediately in the manner and with the
effect specified in this Section.

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

 
                                                                              70

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 6.07.

          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

 
                                                                              71

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.

Trustee:

          (a) semi-annually, not more than 15 days after December 15 and June 15
     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 each series as of
     such December 15 and June 15, as applicable, and

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

provided, however, that if and so long as the Trustee shall be the Security

Registrar for Securities of a series, no such list need be furnished with
respect to such series of Securities.

          SECTION 7.02.  Preservation of Information; Communications to
                         ----------------------------------------------
Securityholders.  (a)  The Trustee shall preserve, in as current a term 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 7.01 and the names and addresses of Holders of Securities received by
the Trustee in its capacity as Security Registrar, it so acting.  The Trustee
may destroy any list furnished to it as provided in Section 701 upon receipt of
a new list so furnished.

          (b)  If three or more Holders 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 six 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

 
                                                                              73

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

          (i) afford such applicants access to the information preserved at the
     time by the Trustee in accordance with Section 7.02(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 7.02(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
7.02(a), a copy of the form of proxy or other communication which is specified
in such request, with reasonable promptness after a tender to the Trustee of the
material to be mailed and of payment, or provision for the payment, of the
reasonable expenses of mailing, unless, within five days after such tender, the
Trustee shall mail to such applicants and file with the Commission, together
with a copy of the material to be mailed, a written statement to the effect
that, in the opinion of the Trustee, such mailing would be contrary to the best
interests of the Holders of 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

 
                                                                              74

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 7.02(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 7.02(b).

     unpaid aggregate not more than one-half of 1% of the principal amount of
     the Securities of such series Outstanding on the date of such report;

 
                                                                              75

     and which the Trustee has not previously reported; and

          (vii) any action taken by the Trustee in the performance of its duties
     hereunder which it has not previously reported and which in its opinion
     materially affects the Securities, except action in respect of a default,
     notice of which has been or is to be withheld by the Trustee in accordance
     with Section 6.02.

          (b)  The Trustee shall transmit by mail to all Securityholders, as
their names and addresses appear in the Security Register, a brief report with
respect to the character and amount of any advances (and if the Trustee elects
so to state, the circumstances surrounding the making thereof) made by the
Trustee (as such) since the date of the last report transmitted pursuant to
Subsection (a) of this Section (or if no such report has yet been so
transmitted, since the date of execution of this instrument) for the
reimbursement of which it claims or may claim a lien or charge, prior to that of
the Securities of any series, on property or funds held or collected by it as
Trustee, and which it has not previously reported pursuant to this Subsection,

advances if such advances remaining unpaid at any time aggregate 10% or less of

     to Section 6.11;

          (g) 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);

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

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

provided, however, that no such supplemental indenture shall, without the
- --------  -------

          (a) change the Maturity of the principal of, or the Stated Maturity of

     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 alter
     the provisions of this Indenture so as to affect adversely the terms, if
     any, of conversion of any Securities into Common Stock or other securities,
     or alter the provisions of Article XIII or the definition of Senior
     Indebtedness so as to affect adversely the rights of any Holder of
     Securities;

 
                                                                              80

     suit for the enforcement of any payment on, or with respect to, the
     Securities of any series on or after the Stated Maturity of such Securities
     (or in the case of redemption, on or after the Redemption Date).

          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 9.03.  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
6.01) 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 be obligated to, enter into any
such supplemental indenture which affects the Trustee's own

 
                                                                              81

          SECTION 9.04.  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 9.05.  Conformity with Trust Indenture Act.  Every
                         ------------------------------------       
supplemental indenture executed pursuant to this Article shall conform to the
requirements of TIA as then in effect.

          SECTION 9.06.  Reference in Securities to Supplemental Indentures.
                         --------------------------------------------------- 
Securities authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article may, and shall if required by the Trustee,
bear a notation in form approved by the Trustee as to any matter provided for in
such supplemental indenture.  If the Company shall so determine, new Securities
so modified as to conform, in the opinion of the Trustee and the Board of
Directors, to any such supplemental indenture may be prepared and executed by
the Company and authenticated and delivered by the Trustee in exchange for
Outstanding Securities.

          SECTION 9.07.  Subordination Unimpaired.  No supplemental indenture
                         -------------------------                           
entered into under this Article shall modify, directly or indirectly, the
provisions of Article XIII or the definition of Senior Indebtedness in Section
1.01 in any manner that adversely affects the rights of the holders of Senior
Indebtedness then outstanding under Article XIII unless written consents are
obtained from holders of such Senior Indebtedness; provided, however, that in
                                                   --------  -------         
any case where the instrument or agreement governing Senior Indebtedness
contains express provisions pertaining to the giving of consent in such
circumstances, such consents shall only be required to the extent they are
required under the terms of such instrument or agreement.

 
                                                                              82

                                   Covenants
                                   ---------

          SECTION 10.01.  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 10.02.  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
registration of transfer or exchange, where notices and demands to or upon the
Company in respect of the Securities and this Indenture may be served and where
any Securities with conversion privileges may be presented and surrendered for
conversion.  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 Corporate Trust Office of the
Trustee, and the Company hereby appoints the Trustee its agent to receive all
such presentations, surrenders, notices and demands.

          Unless otherwise set forth in, or pursuant to, a Board Resolution or
Indenture supplemental hereto with respect to a series of Securities, the
Company hereby initially designates as the Place of Payment for each series of
Securities, the Borough of Manhattan, the City and State of New York, and
initially appoints the Trustee at its Corporate Trust office as the Company's
office or agency for each such purpose in such city.

          SECTION 10.03.  Money for Security Payments To Be Held in Trust.  If
                          ------------------------------------------------    
the Companies 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

 
                                                                              83

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:

          (a) 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;

          (b) 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

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

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture with respect to any series of
Securities or for any other purpose, pay, or by Company Order direct any Paying
Agent to pay, to the Trustee all sums held in trust by the Company or such
Paying Agent in respect of each and every series of Securities as to which it
seeks to discharge this Indenture

 
                                                                              84

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.

          SECTION 10.04.  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:

          (a) 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

          (b) to the best of his knowledge, based on such review, the Company
     has fulfilled all its obligations under this Indenture and has complied
     with all conditions and covenants on its part contained in this

 
                                                                              85

     Indenture through such year, or, if there has been a default in the
     fulfillment of any such obligation, covenant or condition, specifying each
     such default known to him and the nature and status thereof.

          For the purpose of this Section 10.04, default and compliance shall be
determined without regard to any grace period or requirement of notice provided
pursuant to the terms of this Indenture.

          SECTION 10.05.  Legal Existence.  Subject to Article VIII the Company
                          ----------------                                     
will do or cause to be done all things necessary to preserve and keep in full
force and effect its legal existence.

          SECTION 10.06.  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 a Board Resolution or supplemental
indenture with respect to the Securities of such series, unless otherwise
specified in such Board Resolution or supplemental indenture, 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.  Nothing in this Section 10.06
shall permit the waiver of compliance with any covenant or condition set forth
in such Board Resolution or supplemental indenture which, if in the form of an
indenture supplemental hereto, would not be permitted by Section 9.02 without
the consent of the Holder of each outstanding Security affected thereby.


                                   ARTICLE XI

                            Redemption of Securities
                            ------------------------

          SECTION 11.01.  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

 
                                                                              86

fund or analogous obligation or otherwise, by provision therefor in the form of
Security for such series established and approved pursuant to Section 2.02 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 3.01.
Redemption of Securities of any series shall be made, subject to the provisions
of Section 13.03 hereof, 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.  Notwith-standing anything to the contrary in this
Indenture, except in the case of redemption pursuant to a sinking fund, the
Trustee shall not make any payment in connection with the redemption of
Securities until the close of business on the Redemption Date.

          SECTION 11.02.  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 pursuant to authority granted by, a Board
Resolution.  In case of any redemption at the election of the Company of less
than all of the 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 and the Tranche (as defined
in Section 11.03) to be redeemed.

          In the case of any redemption of Securities (a) prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture, or (b) 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 11.03.  Selection by Trustee of Securities To Be Redeemed.  If
                          --------------------------------------------------    
less than all the Securities of like tenor and terms of any series (a "Tranche")
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 Tranche 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 Tranche of a

 
                                                                              87

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 series are to be redeemed, the particular Tranche of
Securities to be redeemed shall be selected by the Company.

          If any convertible Security selected for partial redemption is
converted in part before the termination of the conversion right with respect to
the portion of the Security so selected, the converted portion of such Security
shall be deemed (so far as may be) to be the portion selected for redemption.

          Upon any redemption of fewer than all the Securities of a Series or
Tranche, the Company and the Trustee may treat as Outstanding any Securities

Regular Record Dates according to their terms and the provisions of Section
3.07.

          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal shall, until paid, bear interest

                          ----------------------------

          SECTION 11.08.  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 (a) deliver to
the Trustee for cancellation any Securities of such series theretofore acquired
by the Company or converted by the Holder thereof into Common Stock or other
securities, or (b) receive credit for any Securities of such series (not
previously so credited) acquired by the Company (including by way of optional
redemption (pursuant to the sinking fund or otherwise but not by way of
mandatory sinking fund redemption) or converted by the Holder thereof into
Common Stock or other securities and theretofore delivered to the Trustee for
cancellation, and if it does so (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 sinking fund payment to be satisfied by payment of cash and by
delivery or credit of Securities of such series acquired by the Company or
converted by the Holder thereof 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 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 canceled 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

 
                                                                              91

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 11.06.  The Trustee shall select, in the manner provided in
Section 11.03, 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 11.04 (and with the
effect provided in Section 11.06) 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 11.08.  Any and all sinking fund
moneys with respect to Securities of any series held by the Trustee at the
Maturity of Securities of such series, and not held for the payment or
redemption of particular Securities of such series, shall be applied by the
Trustee, together with other moneys, if necessary, to be deposited sufficient
for the purpose, to the payment of the principal of the Securities of such
series at Maturity.

          On or before each sinking fund Redemption Date provided with respect
to Securities of any series, the Company shall pay to the Trustee in cash a sum
equal to all accrued interest, if any, to the date fixed for redemption on
Securities to be redeemed on such sinking fund Redemption Date pursuant to this
Section 11.08.

          SECTION 11.09.  Rescission of Redemption.  In the event that this
                          -------------------------                        
Section 11.09 is specified to be applicable to a series of Securities pursuant
to Section 3.01 and a Redemption Rescission Event shall occur following any day
on which a notice of redemption shall have been given pursuant to Section 11.04
hereof but at or prior to the time and date fixed for redemption as set forth in
such notice of redemption, the Company may, at its sole option, at any time
prior to the earlier of (a) the close of business on that day which is two
Trading Days following such Redemption Rescission Event and (b) the time and
date fixed for redemption as set forth in such notice, rescind the redemption to
which such notice of redemption shall have

 
                                                                              92

related by making a public announcement of such rescission (the date on which
such public announcement shall have been made being hereinafter referred to as
the "Rescission Date").  The Company shall be deemed to have made such
announcement if it shall issue a release to the Dow Jones News Service, Reuters
Information Services or any successor news wire service.  From and after the
making of such announcement, the Company shall have no obligation to redeem
Securities called for redemption pursuant to such notice of redemption or to pay
the Redemption Price therefor and all rights of Holders of Securities shall be
restored as if such notice of redemption had not been given.  As promptly as
practicable following the making of such announcement, the company shall
telephonically notify the Trustee and the paying Agent of such rescission.  The
Company shall give notice of any such rescission by first-class mail, postage
prepaid, mailed as promptly as practicable but in no event later than the close
of business on that day which is five Trading Days following the Rescission Date
to each Holder of Securities at the close of business on the Rescission Date, to
any other Person that was a Holder of Securities and that shall have surrendered
Securities for conversion following the giving of notice of the subsequently
rescinded redemption and to the Trustee and the Paying Agent.  Each notice of
rescission shall (i) state that the redemption described in the notice of
redemption has been rescinded, (ii) state that any Converting Holder shall be
entitled to rescind the conversion of Securities surrendered for conversion
following the day on which notice of redemption was given but on or prior to the
date of the mailing of the Company's notice of rescission, (iii) be accompanied
by a form prescribed by the Company to be used by any Converting Holder
rescinding the conversion of Securities so surrendered for conversion (and
instructions for the completion and delivery of such form, including
instructions with respect to any payment that may be required to accompany such
delivery) and (iv) state that such form must be properly completed and received
by the Company no later than the close of business on a date that shall be 15
Trading Days following the date of the mailing of such notice of rescission.

 
                                                                              93

                                   ----------

          SECTION 12.01.  Conversion Privilege.  If so provided in a Board
                          ---------------------                           
Resolution with respect to the Securities of any series, the Holder of a
Security of such series shall have the right, at such Holder's option, to
convert, in accordance with the terms of such series of Securities and this
Article XII, all or any part (in a denomination of, unless otherwise specified
in a Board Resolution or supplemental indenture with respect to Securities of
such series, $1,000 in principal amount or any integral multiple thereof) of
such Security into shares of Common Stock or other Marketable Securities
specified in such Board Resolution at any time or, as to any Securities called
for redemption, at any time prior to the time and date fixed for such redemption
(unless the Company shall default in the payment of the Redemption Price, in
which case such right shall not terminate at such time and date).  The
provisions of this Article XII shall not be applicable to the Securities of a
series unless otherwise specified in a Board Resolution with respect to the
Securities of such series.

          SECTION 12.02.  Conversion Procedure; Rescission of Conversion;
                          -----------------------------------------------
Conversion Price; Fractional Shares.  (a)  Each Security to which this Article
- ------------------------------------                                          
is applicable shall be convertible at the office of the Conversion Agent, and at
such other place or places, if any, specified in a Board Resolution with respect
to the Securities of such series, into fully paid and nonassessable shares
(calculated to the nearest one-hundredth of a share) of Common Stock or other
Marketable Securities.  The Securities will be converted into shares of Common
Stock or such other Marketable Securities at the Conversion Price therefor.  No
payment or adjustment shall be made in respect of dividends on the Common Stock
or such other Marketable Securities or accrued interest on a converted Security
except as described in Section 12.09.  The Company may, but shall not be
required to, in connection with any conversion of Securities, issue a fraction
of a share of Common Stock or of such other Marketable Security, and, if the
Company shall determine not to issue any such fraction, the Company shall,
subject to Section 12.03(d), make a cash payment (calculated to the nearest
cent) equal to such fraction multiplied by the Closing Price of the Common Stock
or such other Marketable Security on the last Trading Day prior to the date of
conversion.

 
                                                                              94

          (b)  Before any Holder of a Security shall be entitled to convert the
same into Common Stock or other Marketable Securities, such Holder shall
surrender such Security duly endorsed to the Company or in blank, at the office
of the Conversion Agent or at such other place or places, if any, specified in a
Board Resolution with respect to the Securities of such series, and shall give
written notice to the Company at said office or place that he elects to convert
the same and shall state in writing therein the principal amount of Securities
to be converted and the name or names (with addresses) in which he wishes the
certificate or certificates for Common Stock or for such other marketable
Securities to be issued; provided, however, that no Security or portion thereof
                         --------  -------                                     
shall be accepted for conversion unless the principal amount of such Security or
such portion, when added to the principal amount of all other Securities or
portions thereof then being surrendered by the Holder thereof for conversion,
exceeds the then effective Conversion Price with respect thereto.  If more than
one Security shall be surrendered for conversion at one time by the same Holder,
the number of full shares of Common Stock or such other Marketable Securities
which shall be deliverable upon conversion shall be computed on the basis of the
aggregate principal amount of the Securities (or specified portions thereof to
the extent permitted thereby) so surrendered.  Subject to the next succeeding
sentence, the Company will, as soon as practicable thereafter, issue and deliver
at said office or place to such Holder of a Security, or to his nominee or
nominees, certificates for the number of full shares of Common Stock or other
Marketable Securities to which he shall be entitled as aforesaid, together,
subject to the last sentence of paragraph (a) above, with cash in lieu of any
fraction of a share to which he would otherwise be entitled.  The Company shall
not be required to deliver certificates for shares of Common Stock or other
Marketable Securities while the stock transfer books for such stock or the
transfer books for such Marketable Securities, as the case may be, or the
Security Register are duly closed for any purpose, but certificates for shares
of Common Stock or other Marketable Securities shall be issued and delivered as
soon as practicable after the opening of such books or Security Register.  A
Security shall be deemed to have been converted as of the close of business on
the date of the surrender of such Security for conversion as provided above, and
the person or persons entitled to receive the Common Stock or other Marketable
Securities issuable upon such conversion shall be treated for all purposes as
the record Holder or Holders of such

 
                                                                              95

Common Stock or other Marketable Securities as of the close of business on such
date.  In case any Security shall be surrendered for partial conversion, the
Company shall execute and the Trustee shall authenticate and deliver to or upon
the written order of the Holder of the Securities so surrendered, without charge
to such Holder (subject to the provisions of Section 12.08), a new Security or
Securities in authorized denominations in an aggregate principal amount equal to
the unconverted portion of the surrendered Security.

          (c)  Notwithstanding anything to the contrary contained herein, in the
event the Company shall have rescinded a redemption of Securities Pursuant to
Section 11.09 hereof, any Holder of Securities that shall have surrendered
Securities for conversion following the day on which notice of the subsequently
rescinded redemption shall have been given but prior to the later of (i) the
close of business on the Trading Day next succeeding the date on which public
announcement of the rescission of such redemption shall have been made and (ii)
the date of the mailing of the notice of rescission required by Section 11.09
hereof (a "Converting Holder") may rescind the conversion of such Securities
surrendered for conversion by (A) properly completing a form prescribed by the
Company and mailed to Holders of Securities (including Converting Holders) with
the Company's notice of rescission, which form shall provide for the
certification by any Converting Holder rescinding a conversion on behalf of any
beneficial owner (within the meaning of Rule 13d-3 under the Securities Exchange
Act of 1934) of Securities that the beneficial ownership (within the meaning of
such Rule) of such Securities shall not have changed from the date on which such
Securities were surrendered for conversion to the date of such certification,
and (B) delivering such form to the Company no later than the close of business
on the date which is 15 Trading Days following the date of the mailing of the
Company's notice of rescission.  The delivery of such form by a Converting
Holder shall be accompanied by (I) any certificates representing shares Of
Common Stock or other securities issued to such Converting Holder upon a
conversion of Securities that shall be rescinded by the proper delivery of such
form (the "Surrendered Securities"),(II) any securities, evidences of
indebtedness or assets (other than cash) distributed by the Company to such
Converting Holder by reason of such Converting Holder being a record holder of
Surrendered Securities and (III) payment in New York Clearing House funds or
other

 
                                                                              96

funds acceptable to the Company of an amount equal to the sum of (1) any cash
such Converting Holder may have received in lieu of the issuance of fractional
Surrendered Securities and (2) any cash paid or payable by the Company to such
Converting Holder by reason of such Converting Holder being a record holder of
Surrendered Securities.  Upon receipt by the Company of any such form properly
completed by a Converting Holder and any certificates, securities, evidences of
indebtedness, assets or cash payments required to be returned by such Converting
Holder to the Company as set forth above, the Company shall instruct the
transfer agent or agents for shares of Common Stock or other securities to
cancel any certificates representing Surrendered Securities (which Surrendered
Securities shall be deposited in the treasury of the Company) and shall instruct
the Registrar to reissue certificates representing Securities to such Converting
Holder (which Securities shall be deemed to have been Outstanding at all times
during the period following their surrender for conversion).  The Company shall,
as promptly as practicable, and in no event more than five Trading Days
following the receipt of any such properly completed form and any such
certificates, securities, evidences of indebtedness, assets or cash payments
required to be so returned, pay to the Holder of Securities surrendered to the
Company pursuant to a rescinded conversion or as otherwise directed by such
Holder any interest paid or other payment made to Holders of Securities during
the period from the time such Securities shall have been surrendered for
conversion to the rescission of such conversion.  All questions as to the
validity, form, eligibility (including time of receipt) and acceptance of any
form submitted to the Company to rescind the conversion of Securities, including
questions as to the proper completion or execution of any such form or any
certification contained therein, shall be resolved by the Company, whose
determination shall be final and binding.

          SECTION 12.03.  Adjustment of Conversion Price for Common Stock or
                          ---------------------------------- ---------------
Other Marketable Securities.  The Conversion Price with respect to any Security
- ----------------------------                                                   
which is convertible into Common Stock or other Marketable Securities shall be
adjusted from time to time as follows:

          (a)  In case the Company shall, at any time or from time to time while
     any of such Securities are outstanding, (i) pay a dividend in shares of its
     Common Stock or other Marketable Securities, (ii) combine its outstanding
     shares of Common Stock or other Marketable

 
                                                                              97

     Securities into a smaller number of shares or securities, (iii) subdivide
     its outstanding shares of Common Stock or other Marketable Securities or
     (iv) issue by reclassification of its shares of Common stock or other
     Marketable Securities any shares of stock or other Marketable Securities of
     the Company, the Conversion Price in effect immediately before such action
     shall be adjusted so that the Holders of such Securities, upon conversion
     thereof into Common Stock or other Marketable Securities immediately
     following such event, shall be entitled to receive the kind and amount of
     shares of capital stock of the Company or other Marketable Securities which
     they would have owned or been entitled to receive upon or by reason of such
     event if such Securities had been converted immediately before the record
     date (or, if no record date, the effective date) for such event.  An
     adjustment made pursuant to this Section 12.03(a) shall become effective
     retroactively immediately after the record date in the case of a dividend
     or distribution and shall become effective retroactively immediately after
     the effective date in the case of a subdivision, combination or
     reclassification.  For the purposes of this Section 12.03(a), each Holder
     of Securities shall be deemed to have failed to exercise any right to elect
     the kind or amount of securities receivable upon the payment of any such
     dividend, subdivision, combination or reclassification (provided that, if
     the kind or amount of securities receivable upon such dividend,
     subdivision, combination or reclassification is not the same for each
     nonelecting share, the kind and amount of securities or other property
     receivable upon such dividend, subdivision, combination or reclassification
     for each nonelecting share shall be deemed to be the kind and amount so
     receivable per share by a plurality of the nonelecting shares).

          (b)  In case the Company shall, at any time or from time to time while
     any of such Securities are outstanding, issue rights or warrants to all
     holders of shares of its Common Stock or other Marketable Securities
     entitling them (for a period expiring within 45 days after the record date
     for such issuance) to subscribe for or purchase shares of Common Stock or
     other Marketable Securities (or securities convertible into shares of
     Common Stock or other Marketable Securities) at a price per share less than
     the Current Market Price of the Common Stock or other Marketable

 
                                                                              98

     Securities at such record date (treating the price per share of the
     securities convertible into Common Stock or other Marketable Securities as
     equal to (i) the sum of (A) the price for a unit of the security
     convertible into Common Stock or other Marketable Securities plus (B) any
     additional consideration initially payable upon the conversion of such
     security into Common Stock or other Marketable Securities divided by (ii)
     the number of shares of Common Stock or other Marketable Securities
     initially underlying such convertible security), the Conversion Price with
     respect to such Securities shall be adjusted so that it shall equal the
     price determined by dividing the Conversion Price in effect immediately
     prior to the date of issuance of such rights or warrants by a fraction, the
     numerator of which shall be the number of shares of Common Stock or other
     Marketable Securities outstanding on the date of issuance of such rights or
     warrants plus the number of additional shares of Common Stock or other
     Marketable securities offered for subscription or purchase (or into which
     the convertible securities so offered are initially convertible) and the
     denominator of which shall be the number of shares of Common Stock or other
     Marketable Securities outstanding on the date of issuance of such rights or
     warrants plus the number of shares or securities which the aggregate
     offering price of the total number of shares or securities so offered for
     subscription or purchase (or the aggregate purchase price of the
     convertible securities so offered plus the aggregate amount of any
     additional consideration initially payable upon conversion of such
     Securities into Common Stock or other Marketable Securities) would purchase
     at such Current Market Price of the Common Stock or other Marketable
     Securities.  Such adjustment shall become effective retroactively
     immediately after the record date for the determination of stockholders
     entitled to receive such rights or warrants.

          (c)  In case the Company shall, at any time or from time to time while
     any of such Securities are outstanding, distribute to all holders of shares
     of its Common Stock or other Marketable Securities (including any such
     distribution made in connection with a consolidation or merger in which the
     Company is the continuing corporation and the Common Stock or other
     Marketable Securities are not changed or exchanged) cash, evidences of its
     indebtedness, securities or assets (excluding (i) regular periodic cash
     dividends

 
                                                                              99

     in amounts, if any, determined from time to time by the Board of Directors,
     (ii) dividends payable in shares of Common Stock or other Marketable
     Securities for which adjustment is made under Section 12.03(a) or (iii)
     rights or warrants to subscribe for or purchase securities of the Company
     (excluding those referred to in Section 12.03(b)), the Conversion Price
     with respect to such Securities shall be adjusted so that it shall equal
     the price determined by dividing the Conversion Price in effect immediately
     prior to the date of such distribution by a fraction, the numerator of
     which shall be the Current Market Price of the Common Stock or other
     Marketable securities on the record date referred to below and the
     denominator of which shall be such Current Market Price of the Common Stock
     or other Marketable Securities less the then fair market value (as
     determined by the Board of Directors of the Company, whose determination
     shall be conclusive) of the portion of the cash or assets or evidences of
     indebtedness or securities so distributed or of such subscription rights or
     warrants applicable to one share of Common Stock or one other Marketable
     Security (provided that such denominator shall never be less than one);
     provided, however, that no adjustment shall be made with respect to any
     --------  -------                                                      
     distribution of rights to purchase securities of the Company if a Holder of
     Securities would otherwise be entitled to receive such rights upon
     conversion at any time of such Securities into Common Stock or other
     Marketable Securities unless such rights are subsequently redeemed by the
     Company, in which case such redemption shall be treated for purposes of
     this Section as a dividend on the Common Stock or other Marketable
     Securities.  Such adjustment shall become effective retroactively
     immediately after the record date for the determination of stockholders or
     holders of Marketable Securities entitled to receive such distribution;
     and, in the event that such distribution is not so made, the Conversion
     Price shall again be adjusted to the Conversion Price which would then be
     in effect if such record date had not been fixed.

          (d)  The Company shall be entitled to make such additional adjustments
     in the Conversion Price, in addition to those required by Sections
     12.03(a), 12.03(b) and 12.03(c), as shall be necessary in order that any
     dividend or distribution of Common Stock or other Marketable Securities,
     any subdivision, reclassi-

 
                                                                             100

     fication or combination of shares of Common Stock or other Marketable
     Securities or any issuance of rights or warrants referred to above shall
     not be taxable to the holders of Common Stock or other Marketable
     Securities for United States Federal income tax purposes.

          (e)  In any case in which this Section 12.03 shall require that any
     adjustment be made effective as of or retroactively immediately following a
     record date, the Company may elect to defer (but only for five Trading Days
     following the filing of the statement referred to in Section 12.05) issuing
     to the Holder of any Securities converted after such record date the shares
     of Common Stock or other Marketable Securities and other capital stock of
     the Company issuable upon such conversion over and above the shares of
     Common Stock or other Marketable Securities and other capital stock of the
     Company issuable upon such conversion on the basis of the Conversion Price
     prior to adjustment; provided, however, that the Company shall deliver to
                          --------  -------                                   
     such Holder a due bill or other appropriate instrument evidencing such
     Holder's right to receive such additional shares upon the occurrence of the
     event requiring such adjustment.

          (f)  All calculations under this Section 12.03 shall be made to the
     nearest cent or one-hundredth of a share or security, with one-half cent
     and .005 of a share, respectively, being rounded upward.  Notwithstanding
     any other provision of this Section 12.03, the Company shall not be
     required to make any adjustment of the Conversion Price unless such
     adjustment would require an increase or decrease of at least 1% of such
     price.  Any lesser adjustment shall be carried forward and shall be made at
     the time of and together with the next subsequent adjustment which,
     together with any adjustment or adjustments so carried forward, shall
     amount to an increase or decrease of at least 1% in such price.  Any
     adjustments under this Section 12.03 shall be made successively whenever an
     event requiring such an adjustment occurs.

          (g)  In the event that at any time, as a result of an adjustment made
     pursuant to this Section 12.03, the Holder of any Security thereafter
     surrendered for conversion shall become entitled to receive any shares of
     stock of or other Marketable Securities of the Company other than shares of
     Common Stock or Marketable

 
                                                                             101

     Securities into which the Securities originally were convertible, the
     Conversion Price of such other shares or Marketable Securities so
     receivable upon conversion of any such Security shall be subject to
     adjustment from time to time in a manner and on terms as nearly equivalent
     as practicable to the provisions with respect to Common Stock and
     Marketable Securities contained in subparagraphs (a) through (f) of this
     Section 12.03, and the provisions of Sections 12.01, 12.02 and 12.04
     through 12.09 with respect to the Common Stock or other Marketable
     Securities shall apply on like or similar terms to any such other shares or
     Marketable Securities and the determination of the Board of Directors as to
     any such adjustment shall be conclusive.

          (h)  No adjustment shall be made pursuant to this Section (i) if the
     effect thereof would be to reduce the Conversion Price below the par value
     (if any) of the Common Stock or other Marketable Security, if any, or (ii)
     subject to Section 12.03(e) hereof, with respect to any Security that is
     converted prior to the time such adjustment otherwise would be made.

          SECTION 12.04.  Consolidation or Merger of the Company.  In case of
                          ---------------------------------------            
either (a) any consolidation or merger to which the Company is a party, other
than a merger or consolidation in which the Company is the surviving or
continuing corporation and which does not result in a reclassification of, or
change (other than a change in par value or from par value to no par value or
from no par value to par value, as a result of a subdivision or combination) in,
outstanding shares of Common Stock or other Marketable Securities or (b) any
sale or conveyance of all or substantially all the property and assets of the
Company to another Person, each Security then Outstanding shall be convertible
from and after such merger, consolidation, sale or conveyance of property and
assets into the kind and amount of shares of stock or other securities and
property (including cash) receivable upon such consolidation, merger, sale or
conveyance by a holder of the number of shares of Common Stock or other
Marketable Securities into which such Securities would have been converted
immediately prior to such consolidation, merger, sale or conveyance, subject to
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article XII (and assuming such holder of Common
Stock or other Marketable Securities failed to exercise his rights of

 
                                                                             102

election, if any, as to the kind or amount of securities, cash or other property
(including cash) receivable upon such consolidation, merger, sale or conveyance
(provided that, if the kind or amount of securities, cash or other property
(including cash) receivable upon such consolidation, merger, sale or conveyance
is not the same for each nonelecting share, the kind and amount of securities,
cash or other property (including cash) receivable upon such consolidation,
merger, sale or conveyance for each nonelecting share shall be deemed to be the
kind and amount so receivable per share by a plurality of the nonelecting shares
or securities)).  The Company shall not enter into any of the transactions
referred to in clause (a) or (b) of the preceding sentence unless effective
provision shall be made so as to give effect to the provisions set forth in this
Section 12.04.  The provisions of this Section 12.04 shall apply similarly to
successive consolidations, mergers, sales or conveyances.

          SECTION 12.05.  Notice of Adjustment.  Whenever an adjustment in the
                          ---------------------

     necessary to show the reason for and the manner of computing such
     adjustment, such certificate to be conclusive evidence that the adjustment
     is correct; and

          (b) a notice stating that the Conversion Price has been adjusted and
     setting forth the adjusted Conversion Price shall forthwith be mailed,
     first-class postage prepaid, by the Company to the Holders of record of
     such Outstanding Securities.

          SECTION 12.06.  Notice in Certain Events.  In case:

the Company shall cause to be filed with the Trustee and the Conversion Agent
for the applicable securities, and shall cause to be mailed, first-class postage
prepaid, to the Holders of record of applicable Securities, at least 15 days
prior to the applicable date hereinafter specified, a notice stating (i) the

Marketable Securities of record shall be entitled to exchange their Common Stock
or other Marketable Securities for securities or other property deliverable upon

          Failure to give such notice or any defect therein shall not affect the

          SECTION 12.07.  Company To Reserve Stock or Other Marketable
                          --------------------------------------------
Securities; Registration; Listing.  (a)  The Company shall at all times reserve
- ----------------------------------                                             
and keep available, free from preemptive rights, out of its authorized but
unissued shares of Common Stock or other Marketable Securities, for the purpose
of effecting the conversion of the Securities, such number of its duly
authorized shares of Common Stock or number or principal amount of other
Marketable Securities as shall from time to time be sufficient to effect the
conversion of all applicable outstanding Securities into such

 
                                                                             104

Common Stock or other Marketable Securities at any time (assuming that, at the
time of the computation of such number of shares or securities, all such
Securities would be held by a single Holder); provided, however, that nothing
                                              --------  -------              
contained herein shall preclude the Company from satisfying its obligations in
respect of the conversion of the Securities by delivery of purchased shares of
Common Stock or other Marketable Securities which are held in the treasury of
the Company.  The Company shall from time to time, in accordance with the laws
of the State of Delaware, use its best efforts to cause the authorized amount of
the Common Stock or other Marketable Securities to be increased if the aggregate
of the authorized amount of the Common Stock or other Marketable Securities
remaining unissued and the issued shares of such Common Stock or other
Marketable Securities in its treasury (other than any such shares reserved for
issuance in any other connection) shall not be sufficient to permit the
conversion of all Securities.

          (b)  If any shares of Common Stock or other Marketable Securities
which would be issuable upon conversion of Securities hereunder require
registration with or approval of any governmental authority before such shares
or securities may be issued upon such conversion, the Company will in good faith
and as expeditiously as possible endeavor to cause such shares or securities to
be duly registered or approved, as the case may be.  The Company will endeavor
to list the shares of Common Stock or other Marketable Securities required to be
delivered upon conversion of the Securities prior to such delivery upon the
principal national securities exchange upon which the outstanding Common Stock
or other Marketable Securities are listed at the time of such delivery.

          SECTION 12.08.  Taxes on Conversion.  The Company shall pay any and
                          --------------------                               
all documentary, stamp or similar issue or transfer taxes that may be payable in
respect of the issue or delivery of shares of Common Stock or other Marketable
Securities on conversion of Securities pursuant hereto.  The Company shall not,
however, be required to pay any such tax which may be payable in respect of any
transfer involved in the issue or delivery of shares of Common Stock or other
Marketable Securities or the portion, if any, of the Securities which is not so
converted in a name other than that in which the Securities so converted were
registered, and no such issue or delivery shall be made unless and until the
person requesting such issue has paid to the Company the

 
                                                                             105

amount of such tax or has established to the satisfaction of the Company that
such tax has been paid.

          SECTION 12.09.  Conversion After Record Date.  If any Securities are
                          -----------------------------                       
surrendered for conversion subsequent to the record date preceding an Interest
Payment Date but on or prior to such Interest Payment Date (except Securities
called for redemption on a Redemption Date between such record date and Interest
Payment Date), the Holder of such Securities at the close of business on such
record date shall be entitled to receive the interest payable on such Securities
on such Interest Payment Date notwithstanding the conversion thereof.
Securities surrendered for conversion during the period from the close of
business on any record date next preceding any Interest Payment Date to the
opening of business on such Interest Payment Date shall (except in the case of
Securities which have been called for redemption on a Redemption Date within
such period) be accompanied by payment in New York Clearing House funds or other
funds acceptable to the Company of an amount equal to the interest payable on
such Interest Payment Date on the Securities being surrendered for conversion.
Except as provided in this Section 12.09, no adjustments in respect of payments
of interest on Securities surrendered for conversion or any dividends or
distributions or interest on the Common Stock or other Marketable Securities
issued upon conversion shall be made upon the conversion of any Securities.

          SECTION 12.10.  Corporate Action Regarding Par Value of Common Stock.
                          ----------------------------------------------------- 
Before taking any action which would cause an adjustment reducing the applicable
Conversion Price below the then par value (if any) of the shares of Common Stock
or other Marketable Securities deliverable upon conversion of the Securities,
the Company will take any corporate action which may, in the opinion of its
counsel, be necessary in order that the Company may validly and legally issue
fully paid and nonassessable shares of Common Stock or other Marketable
Securities at such adjusted Conversion Price.

          SECTION 12.11.  Company Determination Final.  Any determination that
                          ----------------------------                        
the Company or the Board of Directors must make pursuant to this Article is
conclusive.

          SECTION 12.12.  Trustee's Disclaimer.  The Trustee has no duty to
                          ---------------------                            
determine when an adjustment under this Article should be made, how it should be
made or what it should be.  The Trustee makes no representation as to the

 
                                                                             106

validity or value of any securities or assets issued upon conversion of
Securities.  The Trustee shall not be responsible for the Company's failure to
comply with this Article.  Each Conversion Agent other than the Company shall
have the same protection under this Section as the Trustee.

                                 Subordination

          SECTION 13.01.  Agreement To Subordinate.  The Company agrees, and
                          -------------------------                         
each Securityholder by accepting a Security agrees, that the indebtedness
evidenced by the Securities and the payment of the principal of (and premium, if
any) and interest on each and all of the Securities is hereby expressly
subordinated in right of payment, to the extent and in the manner provided in

Senior Indebtedness and that such subordination is for the benefit of the
holders of Senior Indebtedness.

whether voluntary or involuntary, or upon any reorganization, readjustment,
arrangement or similar proceeding relating to the Company or its property,
whether or not the Company is a party thereto and whether in bankruptcy,
insolvency, receivership or similar proceedings, or upon any assignment by the
Company for the benefit of creditors or upon any other marshaling of the assets
and liabilities of the Company:

          (a) all Senior Indebtedness shall first be paid in full in cash or
     cash equivalents, or provisions made for such payment by deposit thereof in
     trust with a bank or banks (either theretofore acting as trustees under
     indentures pursuant to which Senior Indebtedness shall have been issued or
     duly appointed paying agents for the purpose), before any payment or
     distribution, whether in cash, property or securities (other than
     securities of the Company as reorganized or readjusted, or securities of
     the Company or any other corporation provided for by a plan of
     reorganization or readjustment, the payment of which is subordinate, at
     least to the extent provided in this Article with respect to the
     Securities, to the payment of all indebtedness of the

 
                                                                             107

     nature of Senior Indebtedness, so long as the rights of the holders of the
     Senior Indebtedness are not altered adversely by such reorganization or
     readjustment ("Equivalent Securities")), is made on account of the
     principal of or interest on the indebtedness evidenced by the Securities;

          (b) any payment or distribution of any kind or character in respect of
     the principal of or interest on the Securities, whether in cash, property
     or securities (other than Equivalent Securities), to which the Holders of
     the Securities would be entitled except for the provisions of this Article
     shall be paid or delivered by the Company or the liquidating trustee or
     agent or other person making such payment or distribution, whether a
     trustee in bankruptcy, a receiver or liquidating trustee or other trustee
     or agent, directly and ratably to the holders of Senior Indebtedness or
     their Representatives (subject to any subordination of any class of Senior
     Indebtedness, by the provisions thereof, to any other class or classes of

     extent necessary to make payment in full of all Senior Indebtedness
     remaining unpaid, after giving effect to any concurrent payment or
     distribution, or provision therefor, to the holders of such Senior

          (c) in the event that, notwithstanding the foregoing, any payment or
     distribution of any kind or character in respect of the principal of or
     interest on the Securities, whether in cash, property or securities (other
     than Equivalent Securities), shall be received by the Trustee or the
     holders of the Securities before all Senior Indebtedness is paid in full,
     or provision made as aforesaid for its payment, such payment or
     distribution shall be held in trust for the ratable benefit of and shall be
     ratably paid over or delivered to the holders of Senior Indebtedness
     remaining unpaid or unprovided for or their Representatives, as provided in
     the foregoing subparagraph (b), for application to the payment of all
     principal of, and premium, if any, and interest on, such Senior
     Indebtedness remaining unpaid until all such Senior Indebtedness shall have
     been paid in full, after giving effect to any concur-

provisions being made as aforesaid for its payment, the Holders of the
Securities shall be subrogated to the rights of the holders of Senior
Indebtedness to receive payments or distributions of cash, property or

provisions of Section 13.04 hereof, in the event and during the continuation of
any default in the payment of principal of, or premium, if any, or interest on,
or other monetary obligation with respect to, any Senior indebtedness beyond any
applicable period of grace, or in the event that any event of default with
respect to any Senior Indebtedness shall have occurred and be continuing, unless
and until such default or event of default shall have been cured or waived or
shall have ceased to exist, no payment of principal or interest shall be made by
the

 
                                                                             109

Company on the Securities.  Nothing contained in this Article or elsewhere in
this Indenture, or in any of the Securities, shall, however, (a) prevent the
Company from setting aside in trust as provided in Section 10.03 or depositing
with the Trustee, at any time, except during the pendency of any of the
proceedings or upon the happening of any of the events referred to in the first
paragraph of Section 13.02 or during the continuation of any such default or
event of default (not cured or waived), moneys for the payment of principal of
or interest on the Securities or (b) prevent the application by the Trustee of
any moneys deposited with it hereunder by the Company to the payment of or on
account of the principal of or interest on the Securities, if, at the time of
such deposit, the Trustee did not have written notice of any event prohibiting
the making of such deposit by the Company.

          The Company shall give prompt written notice to the Trustee of any
facts which would prohibit the making of any payment of moneys to or by the
Trustee, including any dissolution, winding up, liquidation or reorganization of
the Company within the meaning of this Article.  Anything in this Article or
elsewhere in this Indenture contained to the contrary notwithstanding, the
Trustee shall not be charged with knowledge of the existence of any Senior
Indebtedness or of any default or event of default with respect to any Senior
Indebtedness or of any other facts which would prohibit the making of any
payment of moneys to or by the Trustee, unless and until the Trustee shall have
received notice in writing to that effect signed by an officer of the Company or
by a holder of Senior Indebtedness who shall have been certified by the Company
or otherwise established to the reasonable satisfaction of the Trustee to be
such holder or by a Representative of Senior Indebtedness.

          SECTION 13.04.  Disputes with Holders of Certain Senior Indebtedness.
                          ----------------------------------------------------- 
Any failure by the Company to make any payment on or perform any other
obligation under Senior Indebtedness, other than any indebtedness incurred by
the Company or assumed or guaranteed, directly or indirectly, by the Company for
money borrowed (or any deferral, renewal, extension or refunding thereof) or any
indebtedness or obligation in which the provisions of this Section shall have
been waived by the Company in the instrument or instruments by which the Company
incurred, assumed, guaranteed or otherwise created such indebtedness or
obligation, shall not be deemed a default or event of default under Section
13.03 hereof for so long as (a) the

 
                                                                             110

Company shall be disputing its obligation to make such payment or perform such
obligation and (b) either (i) such dispute shall not have resulted in a judgment
against the Company or the applicable Subsidiary that shall have remained
undischarged or unbonded and have remained in force for more than the applicable
appeal period or (ii) in the event of such a judgment, the Company or the
applicable Subsidiary shall in good faith be prosecuting an appeal or other
proceeding for review and which a stay of execution shall have been obtained
pending such appeal or review.

          SECTION 13.05.  Acceleration of Notes.  If an Event of Default, other
                          ----------------------                               
than an Event of Default under paragraph (e) or (f) of Section 5.01, shall have
occurred and be continuing, the Trustee or the Holder of Securities electing to
accelerate the Securities pursuant to Section 5.02 shall give the
Representatives of the Senior Indebtedness five days' prior written notice
before accelerating the Securities, which notice shall state that it is a
"Notice of Intent to Accelerate"; provided, however, that the Trustee or such
                                  --------  -------                          
Holders may so accelerate the Securities immediately without such notice if at
such time payment of any Senior Indebtedness shall have been accelerated.  If
payment of the Securities is accelerated because of an Event of Default, the
Company shall promptly notify holders of Senior Indebtedness (or their
Representatives) of the acceleration.

          SECTION 13.06.  When Distribution Must Be Paid Over.  If a
                          ------------------------------------      
distribution is made to Securityholders that because of this Article should not
have  been made to them, the Securityholders who receive the distribution shall
hold it in trust for holders of Senior Indebtedness and pay it over to them as
their interests may appear.

          SECTION 13.07.  Relative Rights.  This Article defines the relative
                          ----------------                                   
rights of Securityholders and holders of Senior Indebtedness.  Nothing in this
Indenture shall:

          (a) impair, as between the Company and Securityholders, the obligation
     of the Company, which is absolute and unconditional, to pay principal of
     and interest on the Securities in accordance with their terms;

          (b) affect the relative rights of Securityholders and creditors of the
     Company other than holders of Senior Indebtedness; or

 
                                                                             111

     (c) prevent the Trustee or any Securityholder from exercising its available
     remedies upon an Event of Default, subject to the rights of holders of
     Senior Indebtedness to receive distributions otherwise payable to
     Securityholders.

          If the Company fails because of this Article to pay principal of or
interest on a Security on the due date, the failure is still an Event of
Default.

          SECTION 13.08.  Subordination May Not Be Impaired by Company.  No
                          ---------------------------------------------    
right of any holder of Senior Indebtedness to enforce the subordination of the
indebtedness evidenced by the Securities shall be impaired by any act or failure
to act by the Company or by its failure to comply with this Indenture.

          SECTION 13.09.  Distribution or Notice to Representative.  Whenever a
                          -----------------------------------------            
distribution is to be made or a notice given to holders of Senior Indebtedness,
the distribution may be made and the notice given to their Representative.

          SECTION 13.10.  Rights of Trustee and Paying Agent.  The Trustee or
                          -----------------------------------                
Paying Agent may continue to make payments on the Securities until it receives
notice satisfactory to it that payments may not be made under this Article.  The
Company, a Representative or a holder of Senior Indebtedness who shall have been
certified by the Company or otherwise established to the reasonable satisfaction
of the Trustee to be such holder may give the notice; provided, however, that if
                                                      --------  -------         
an issue of Senior Indebtedness has a Representative, only the Representative
may give the notice on behalf of the holders of Senior Indebtedness.

          The Trustee in its individual or any other capacity may hold Senior
Indebtedness with the same rights it would have if it were not Trustee.  The
Security Registrar, the Paying Agent and the Conversion Agent may do the same
with like rights.

          SECTION 13.11.  Notice to Trustee.  The Company shall give prompt
                          ------------------                               
written notice to a Trust Officer at the address of the Trustee determined
pursuant to Section 1.05 of any fact known to the Company which would prohibit
the making of any payment to or by the Trustee in respect of the Securities.

 
                                                                             112

          SECTION 13.12.  Trustee Not a Fiduciary.  The Trustee shall not be
                          ------------------------                          
deemed to owe any fiduciary duty to the holders of Senior Indebtedness, but
shall have only such obligations to such holders as are expressly set forth in
this Article XIII.

          SECTION 13.13.  Effectuation of Subordination by Trustee.  Each holder
                          -----------------------------------------             
of Securities, by his acceptance hereof, authorizes and directs the Trustee on
his behalf to take such action as may be necessary or appropriate to effectuate
the subordination provided in this Article and appoints the Trustee his
attorney-in-fact for any and all such purposes.

          SECTION 13.14.  Article Applicable to Paying Agents.  In case at any
                          ------------------------------------                
time any Paying Agent other than the Trustee and the Company shall have been
appointed by the Company and be then acting hereunder, the term "Trustee" as
used in this Article shall in such case (unless the context shall require
otherwise) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article in addition to or in place of the Trustee.

          SECTION 13.15.  Trustee; Compensation Not Prejudiced.  Nothing in this
                          -------------------------------------                 
Article shall apply to claims of, or payments to, the Trustee pursuant to
Section 6.07.


          IN WITNESS WHEREOF, the parties hereto have caused this Indenture to
be duly executed as of the day and year first above written.
